Chronic illness requiring attention and management during a long period of time puts great burden onto patients, their family and society. For patients with chronic illnesses, providing social support is the most important, and the fundamental support comes from their spouses. Amount and quality of support from spouses seems to differentiated according to the sex of patients. Female patients tend to believe that their spouses are not very supportive. Therefore, the researchers assessed the burden of husbands of female arthritis patients to discover the factors that result in greater burden. Also, they developed a theoretical model of husbands′ care for their wives through a qualitative research into husbands′ experience. Method 1: The study material was 650 female arthritis patients registered in an arthritis clinic. The questionnaire about the disease experience of female arthritis patients and the burden of husbands were sent. Returned questionnaires numbered 210(32.3%) and 27 were excluded because of inadequate answers. The remaining 183 questionnaires were analyzed. The mean age of the patients was 51 years and the mean age of spouses was 55 years. The mean marital period was 28 years. The average duration since diagnosis was 9.1 years. Education level was varied from primary school to graduate school, and average income/month was 1,517,300 won. Method 2: Initial questionnaire studies on the burden of husbands were performed. Among 183 responding husbands, 23 consented to participate for a qualitative research. Data was obtained by direct and telephone interviews. The mean age of participants was 58 years, and the educational level and socioeconomic status also varied. Result: 1. Husbands′ burden: The average burden was 57.68 with a range of 6-96. 2. Burden and general characteristics: The husband′s burden correlated with the age of the patients, numbers in the family, therapy methods, patient′s level of discomfort, patient′s disease severity, patient′s level of dependence and the husband′s understanding of the level of severity. 3. Linear correlation analysis on burden: The husbands′ burden is explained in 22.5% by husband′s recognition of level of severity and husbands′ age. 4. There were four patterns of the burden on husbands: both objectve burden and subjective burden were high(pattern I), both of objectve burden and subjective burden were low(pattern II), objective burden was high but subjective burden was low(pattern III), objective burden was low but subjective burden was high(pattern IV). The pattern was correlated with the family income, educational level of the patients and their husbands, therapy methods, patient′s level of discomfort, patient′s disease severity, patient′s level of dependence and husband′s understanding of level of severity. 5. The core category of the caring experience of the husbands with arthritis patients was "companionship". The causal factor was the patients′ experience due to symptoms : physical disfigurement, pain, immobility, limitation of house chores, and limitation of social activities. Contextural factors are husbands′ identification of housework and husbands′ concern about the disease. The mediating factors are economic problems, fear of aging, feeling of limitation and family support. The strategy for interaction is mind control and how to solve emotional stress. The "companionship" resulted from caring activities, participation of household activities, helping patients′ to coping with emotional experience. 6. Companionship is established through the process of entering intervention, and caring state of mind. Entering intervention is the phase of participation of therapy and involvement of houseworks. The caring phase consists of decision on therapy, providing therapy, providing direct care, and taking over the household role of wife. Through caring phase, the changing phase set a stage in which husbands consolidate the relationship with their wives, and are reminded of the meaning of marriage. As a result, in changing phase, husbands′ companionship is enhanced. In conclusion, nursing care of chronic illnesses should include a family member especially the spouse. All information on disease shoud be provided to patients and whole family member. Strong support should also be provided to overcome difficulties in taking over role of other sex. Then the quality of life of patients and families will be much improved.

This paper focuses on the interpretation of radiation fluxes from active galactic nuclei. The advantage of positron annihilation spectroscopy over other methods of spectral diagnostics of active galactic nuclei (therefore AGN) is demonstrated. A relationship between regular and random components in both bolometric and spectral composition of fluxes of quanta and particles generated in AGN is found. We consider their diffuse component separately and also detect radiative feedback after the passage of high-velocity cosmic rays and hard quanta through gas-and-dust aggregates surrounding massive black holes in AGN. The motion of relativistic positrons and electrons in such complex systems produces secondary radiation throughout the whole investigated region of active galactic nuclei in form of cylinder with radius R= 400-1000 pc and height H=200-400 pc, thus causing their visible luminescence across all spectral bands. We obtain radiation and electron energy distribution functions depending on the spatial distribution of the investigated bulk of matter in AGN. Radiation luminescence of the non-central part of AGN is a response to the effects of particles and quanta falling from its center created by atoms, molecules and dust of its diffuse component. The cross-sections for the single-photon annihilation of positrons of different energies with atoms in these active galactic nuclei are determined. For the first time we use the data on the change in chemical composition due to spallation reactions induced by high-energy particles. We establish or define more accurately how the energies of the incident positron, emitted ${\gamma}-quantum$ and recoiling nucleus correlate with the atomic number and weight of the target nucleus. For light elements, we provide detailed tables of all indicated parameters. A new criterion is proposed, based on the use of the ratio of the fluxes of ${\gamma}-quanta$ formed in one- and two-photon annihilation of positrons in a diffuse medium. It is concluded that, as is the case in young supernova remnants, the two-photon annihilation tends to occur in solid-state grains as a result of active loss of kinetic energy of positrons due to ionisation down to thermal energy of free electrons. The single-photon annihilation of positrons manifests itself in the gas component of active galactic nuclei. Such annihilation occurs as interaction between positrons and K-shell electrons; hence, it is suitable for identification of the chemical state of substances comprising the gas component of the investigated media. Specific physical media producing high fluxes of positrons are discussed; it allowed a significant reduction in the number of reaction channels generating positrons. We estimate the brightness distribution in the ${\gamma}-ray$ spectra of the gas-and-dust media through which positron fluxes travel with the energy range similar to that recorded by the Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA) research module. Based on the results of our calculations, we analyse the reasons for such a high power of positrons to penetrate through gas-and-dust aggregates. The energy loss of positrons by ionisation is compared to the production of secondary positrons by high-energy cosmic rays in order to determine the depth of their penetration into gas-and-dust aggregations clustered in active galactic nuclei. The relationship between the energy of ${\gamma}-quanta$ emitted upon the single-photon annihilation and the energy of incident electrons is established. The obtained cross sections for positron interactions with bound electrons of the diffuse component of the non-central, peripheral AGN regions allowed us to obtain new spectroscopic characteristics of the atoms involved in single-photon annihilation.

Human health is an integral part of experience in the process of Human Becoming. Through continual interaction with the environment human beings freely choose experience and develop as responsible beings. The process of the health experience of patient with terminal cancer is a unique. he objective of this study is to understand the lived experience of patients with terminal cancer in order to provide basic information for nursing care in the clinical setting and to develop a theoretical background for clinical practice. This study is to de-scribe and define the lived experience of patients with terminal cancer in order to provide a foundation for nursing research and education. Data collection has been done between December 1993 and November 1994. The subjects included five persons -four females and one male : one who was in her sixties, one in his fifties, two in their forties, and one who was in her thirties. The researcher has met with these patients 35 times, but at eight times the patient was in a stuporous condition and not able to participate, so these were not included in the data analysis. Parse's "Human Becoming Methodology", an existential phenomenological research methodology is used for this study. Data has been collected using he dialogical engagement process of "I and You", the participant researcher and the participant subject. Dialogical engagement was discontinued when the data was theoretically saturated. Data was analyzed using the extraction - synthesis and heuristic interpretation. The criteria of Guba and Lincoln(1985). and Sandelo wski(1986) : credibility, auditability, fitness and objectivity were used to test the validity and reliability of the data. The following is a description of the structure of the lived experience of patients with terminal cancer as defined by this study : 1. Structure : 1) Suffering through the reminiscence of past experience 2) The appearance of complex emotions related to life and connectedness 3) The increasing importance of significant people and of the Absolute Being 4) The increasing realization of the importance of health and belief 5) Desire for a return to health and a peaceful life or for acceptance of dying and a comfortable death In summary the structure of the lived experience of these patients can be said to be : suffering comes through reminiscence of past experience, and there are complex emotions related to life and connectedness. Significant people and the Absolute Being become increasingly important along with a realization of the importance of health and faith. And finally there is a desire for either a return to health and a peaceful life or for the acceptance of dying and a comfortable death. 2. Heuristic Interpretation : Using Parse's Human Becoming Methodology, the structure of the lived experience of patients with terminal cancer identified in this research is interpreted as. The lived experience of patients with terminal cancer involves the solving of past conflicts, and the experience of the healing and valuing of sorrow and pain. Through the relation of life and health, and the complex emotions that arise, the lived experience of revealing - concealing is of paradoxical emotions. The increasing importance of significant others and of the Absolute Being shows Connecting and Separating an on- going process of nearness and farness. Revision of thoughts about health and faith is interpreted as transforming and desire for restoration to health and a peaceful life or acceptance of dying and a cowfortable death, as powering. In summary, it is possible to see, in the lived experience of patients with terminal cancer, the relationship of the five concepts of Parse's theory : valuing, revealing -concealing, connecting-separating, transforming, and powering. From Parse's theory, the results of this study show that meaning is related to valuing, rhythmicity to revealing-concealing and connect-ing-separating, and cotranscendence to transforming and powering.

Background: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. Methods: We conducted a multicenter, prospective, non-interventional study. Patients with $CHADS_2{\geq}1$ and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. Results: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had $CHADS_2{\geq}2$ and 83.6% had $CHA_2DS_2-VASc{\geq}2$. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. Conclusion: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

The caregiving experiences of 100 family menbers of outpatients with schizophrenia and schizoaffective disorders were investigated for the presence of positive(positive family-patient relationship. patient' contribution to the family) and negative caregiving experience(objective and subjective burden) and their predictors. This study attempts to make the analysis of caregiving experience more useful by expanding the focus to incoporate these positive aspects of the experience of family caregiver. Objective burden consists of two elements: 'disruption of family life', 'care'(amount of caregiving related to activity of daily living). Subjective burden is defined as emotional reactions to the care giving and it comprised of 6 emotional subdimensions such as 'stigma', 'grief'. 'worry', 'pity', 'fear', 'despair'. Also we investigate the severity of patients' disturbing behaviors into two categories, positive and negative disturbing behaviors and patient' contribution to the family as a predictors of positive and negative caregiving experiences. This study use Pearson's correlation coefficient, Hierardhical regressions in the SAS Program. The results are as follows: 1. Respondents reported moderate level of objective burden 'disruption of family life' (mean = 2.48, range = 1-4), and 'care' (mean=2.54, range = 1-4), and slightly high level of total subjective burden(mean = 2.19, range = 1-4). Mean scores for the measure of the severity of behavioral disturbance indicated that the caregiver experienced negative disturbing behaviors around almost 'somtimes'(mean=2.28, range = 1-4), and positive disturbing behaviors 'almost not frequent'(mean=2.78. range=1-4). So they reported that they perceived patient's negative disturbing behaviors more than positive disturbing behaviors. Mean scores for the measure of the patient' contributions (mean = 1.99. range = 1-4) indicated that caregivers experienced these contributions a little. It means that there should be a positive aspect of possibilities of patient' family roles that can be developed in the daily life. Mean scores for the measure of the positive family-patient relationship indicated that caregivers experienced moderate level of positive family-patient relationship(mean=2.52, range = 1-4). 2. Hierardhical regression analysis 1) Hierardhical regression of 'disruption of family life' showed that the interaction between positive disturbing behaviors and patient' contributions (B = .20. p = .022) and caregiver's educational level(B=.06. p=.000) were 'significant and Hierardhical regression of 'care' showed that 'negative disturbing behaviors'(B= .35. p= .007). 'patient' contributions'(B= .28, p= .019). 'family income'(B=-.l1. p=.096) were significant. 2) Hierardhical regression of 'total subjective burden', 'stigma', 'grief', 'worry', 'pity'. 'fear', 'dispair' showed that 'positive disturbing behaviors'(B=.51. p=.000). 'negative disturbing behaviors' (B = .17, p = .026), 'caregiver's educational level'(B = .03. p=.036), 'family income'(B=.08. p=.041) were significant predictors of 'total subjective burden': 'positive disturbing behaviors'(B=.32. p=.066). 'negative disturbing behaviors'(B=.24, p=.096) 'durations of illness'(B= .03. p= .079) were significant predictors of 'stigma' 'negative disturbing behaviors'(B=.28. p=.005). 'patient sex'(B=-.32. p=.022). 'positive disturbing behaviors'(B=.28. p=.020), 'patient age'(B=.02. p=.010), 'caregiver age'(B=-01, p= .002) were significant predictors of 'grief' 'negative disturbing behaviors'(B= .28, p= .005). 'patient sex'(B= -.32. p=.039), 'caregiver age'(B=-.02, p= .023). 'caregiver's educational level'(B= .04, p = .044) were significant predictors of 'worry' 'patient sex'(B=-.46. p=.005). 'negative disturbing behaviors'(B= .28. p=.018), 'caregiver age'(B=-.01, p=.037) were significant predictors of 'pity' 'positive disturbing behaviors'(B=.83. p=.000). 'patient' contributions' (B = .22, p =.017). 'family income'(B=.09. p=.65) were significant predictors of 'fear' 'positive disturbing behaviors'(B=.49, p=.001). 'negative disturbing behaviors'(B= .24. p=.057) 'patient sex'(B=-.4l, p=.017), 'family income'(B=.14, p=.047) were significant predictors of 'dispair'. 3) Hierardhical regression of 'positive relationship' showed that 'patient contributions'(B=.32, p=.000). 'negative disturbing behaviors'(B= .24, p= .005), 'patient sex'(B=-.23, p=.036).

포유류의 난자가 수란관내로 배란될 때는 난포액 성분도 같이 수란관내로 들어간다. 본 연구에서는 처음으로 난포액의 일부 성분이 수란관액에 의해서 변화하는 것을 관찰하였다. 사람의 난포액을 gelatin zymogram으로 분석한 결과 621kDa gelatinase 이외에 110kDa gelatinase (GA110) 등의 여러 gelatinase 활성이 나타났다. 이 활성들은 EDTA나 phenanthroline에 의해 억제된 반면 PMSF 처리에 의해서는 아무런 변화가 없었다. 소의 수란관액에서는 62kDa gelatinase의 활성만이 주로 관찰되었다. 소의 수란관 액과 사람의 난포액을 1:1로 섞고 이를 37$^{\circ}$C에서 3시간 동안 둔 결과 사람의 난포액의 GA110 활성은 사라졌다. 사람의 난포액에 APMA를 첨가한 결과 GA110의 활성은 대부분 감소하고 대신 62kDa gelatinase의 활성은 오히려 증가하였다. 반면에 사람의 난포액에 EDTA를 3시간 동안 처리한 결과 GA110의 활성은 오히려 현저히 증가하였고 이 때 다른 gelatinases의 활성은 영향을 받지 않았다. PMSF나SBTI는 난포액내의 gelatinases활성에 아무런 변화를 일으키지 않았다. EDTA, PMTA 혹은 SBTI 등의 proteinase inhibitor를 미리 처리한 사람의 난포액에 소의 수란관 내액을 섞은 경우에도GA110의 활성은 여전히 감소하였다. 사람의 혈청에서도 EDTA에 의해 활성이 현저히 증가하는 GA110이 발견되었다. 사람의 난포액과 유사하게 혈청내의 GA110도 소의 수란관액에 의하여 활성이 사라졌다. 그러나 사람의 난포과립세포의 추출물에서는 단지 92kDa gelatinase만 관찰이 되었다. 마지막으로 anti-human gelatinase A 항체를 사용하여 사람의 난포액과 혈청 그리고 난포과립세포의 추출액을 western blotting한 결과 621kDa과 GA110 만이 항원-항체 반응을 나타내었다. 이 같은 결과로 미루어 사람의 난포액과 혈청에는 gelatinase A의 독특한 isoform인 GA110이 있으며 특히 난포액내의 GA110은 수란관액성분에 의해 선택적으로 분해되는 것으로 여겨진다.

Numerous research reports have substantiated the role of stressful life events in relation to the onset of health changes. The relationship tends to hold across different age groups. Theoretically, adolescence has been considered a developmental crisis period of great stress, impoverished coping skills and high vulnerability to biological, social and psychological demands. The research problem addressed by this study was to examine the relationships between stressful life events and health symptom patterns, and the effect of two variables, coping and social, support, theoretically considered to mediate the relationship between stress and health symptoms in adolescents. The following five hypotheses were tested in this research : 1. Health symptoms are positively related to stressful life events in adolescents, 2. Health symptoms are negatively related to coping in adolescents, 3. Health symptoms are negatively related to social support in adolescents, 4. When coping is controlled, the relationship between health symptoms and stressful life events will decrease, and 5. When social support is controlled, the relationship between health symptoms and stressful life events will increase. The study subjects consisted of 1090 high school students of the metropolitan city of Seoul. The following sampling procedure was used : 1. Of the 169 high schools in nine school administrative districts in the city, a proportional sample of ten schools was selected. 2. One class from each of the freshman and sophomore was randomly selected and all the students who were in the sampled class were used as the study sample. The study was limited to freshman and sophomore adolescents, aged 15 to 18(mean＝16.6). Of the 1090 subjects 688(63%) were boys and 402(37%) were girls. An Adolescent Inventory of Stressful Life Events, a Health Symptom Questionnaire and an Adolescent Coping Inventory were adapted for this study. The Norbeck Social Support questionnaire was utilized to collect the data on perceived social support. Five high school teachers in the areas of school health and counselling reviewed the items of each questionnaire for content validity. A pilot study was undertaken to ascertain reliability. Fifty three high school students responded to the questionnaires and gave their opinions on the items. For stressful life events, health symptoms, coping, and social support, the Cronbach's alpha's on the study were .70, .94, .77, and .76, respectively. Research assistants attended all the sampled classes with the school proctor to explain the purpose and procedures of the study to the students. The questionnaires along with a ballpoint pen were distributed to the students who were asked to complete each item. The research assistants left the ballpoint pen with the students as a gift for their cooperation. An average of 50 minutes was required to complete the questionnaires. Using an SPSS, the first, three hypotheses were tested using Gamma, a measure of association for ordinal variables. Partial gamma was used to test the fourth and fifth hypotheses. Patterns of elaboration described by Babbie were selected to interpret the relationship of the three variable analyses. The significance of gamma was determined by Chisquare at a .05 level of significance. There was a positive relationship between health symptoms and stressful life events(Gamma＝.35, p＝.000). Thus the first hypothesis was supported. Unexpectedly, coping was positively related with health symptoms(Gamma＝.13, p＝.000). That is, the higher the coping levels, the greater number of health problems. The third hypothesis, the higher the level of social support, the fewer the health symptoms, was not accepted in this adolescent study group. When coping was controlled, under the condition of low coping the association between health symptoms and stressful life events increased significantly to a partial gamma of .39, and under the condition of high coping it was .30. According to the elaboration model, when one partial relationship is the same or greater than the original and the other is smaller, the control variable should be considered to be specifying the conditions. When social support was controlled the relationship between stressful life events and health symptoms increased under the condition of low social support, but with high social support, the relationship decreased. Both partial gamma were statistically significant at .05 level(.43 and .26 relatively). It can be interpreted that stressful life events are strongly and positively related to health symptoms under the condition of low social support, however this relationship can not be expected with high social support. Thus, the last two hypotheses were conditionally sustained. In this study, the relationships between stressful life events and health symptoms, and the specified me diating roles of coping and social support were found to have statistical interaction. This finding supports the theoretical position of this study. It suggests that stressful life events would create high susceptability to biological social and psychological health symptoms and coping and social support buffering the relationship between stressful life events and health symptom. The findings of this study have implications for nursing practice. When adolescents are confronted with non-developmental life events that are perceived as stressful, nurses should recognize the evidence of the stress-buffering effect of coping and social support on health symptoms and utilize the diverse sources of social support that are readily available to adolescents.

In our society today, a variety of medical caring system, along with a scientific development in the area of oriental medical science plus national demand, has increased the augmentation and the opening of oriental wards and hospitals (Han Bang), which has come to create an additional requirement of nursing activity at oriental medicine wards should be different from that of the general wards or the same as the other. In view of this, various studies need to be made in this connection. The purpose of this study is to comprehend the number of nurses who want to work at oriental medicine wards and measure job satisfaction in nursing as compared with those working at general wards so as to provide basic materials for future assignment and supplementary training for the nurses. An attempt was made to contribute toward nursing administration on the one hand improving nursing training course on the other hand. A total of 72 nurses currently working at two oriental medicine hospitals available in Seoul and 82 general nurses were selected for this study using the questionaire from December 1993 to January 1994. An instrument for the study was based on the measurement of work satisfaction developed by Paula L. Stamps including 37 questions complemented by Kim for revision (1993) and 14 questions regarding general characteristics and oriental medicine wards. The instrument to test dependability showed Cronbach's=0.7711. The collected data have been processed by computer package SPSS. General characteristics of the two groups and the matters involved in oriental medicine wards were calculated into real figure and percentage an similarities between the two groups were analyzed by t-test and F-test according to the characteristics of variables. The comparative test on work satisfaction among the two groups including general characteristics and work factors were conducted by t-test and F-test. The major findings as a result of the study are as follows : 1. As general characteristics, age group of $26{\sim}30$ years are more than any segment of age. As to marital status, the number of those in single status is slightly higher than the married. Approximately 80% of them are graduates of nursing schools and nursing colleges. They are mostly in service for one to three years. There is no significant difference between the two groups. 2. The number of those who want to work at oriental medicine wards represents 40.3% against 58.4%, being in favor of general wards. 3. The reason for service at oriental medicine wards is that "there is room for potential research" which happened to rank first, followed by "easy job," "good working atmosphere" and "growing interest in oriental medicine." 4. Work satisfactions among nurses who work at oriental medicine wards prove greater than that of nurses who work at general wards. 5. Work satisfaction between the two groups by work factors is reflected with significant difference statistically on task requirement, interaction and doctor-nurse relationships. 6. The general charcateristics and the work satisfaction by work factors prove that there are significant difference in age, marital status, education and the period of work. They tend to be more satisfied with the work as they grow in age. Significant differneces are found in the work factors such as autonomy, adiministration and professional job in the relationship with doctor-nurse. As to marital status, the married are more satisfied than the unmarried. There are significant differneces in the factors respecting administration and doctor-nurse college graduates are highly satisfied with task requirement. However, satisfaction with the professional level has proven the highest degree for those having master degree. The period of work and satisfaction : There are significant differneces in task requirement, administration, interactions, professional level and doctor-nurse relationships. As a general rule, the degree of satisfactions is in proportion to the lengrh of service. The following conclusions are drawn based on the fndings mentioned above. Even though the work satisfaction of the nurse who work at oriental medicine ward is relatively high, it is desired that personal consultation be given as to disposition of nurses when they are assigned to oriental medicine wards. It is also recommended that lectures on oriental medicine be conducted through supplementary training and/or basic nursing course in order that they may be motivated for ingenious activities with an increasing sense of self-esteem which will eventually enhance positive changes for the patients who are in need of oriental medicine nursing and for the medical teams. In addition, joint reseaches involvingclinical care and education should be in constant process for unique and scientific development for those who are subject to oriental medicine nursing care.

Experiments were conducted to determine the effects of soybean meal (SBM) as a source of protein and sago meal (SM) as a source of carbohydrate on in situ and in vivo digestibility of dietary components in four male goats (Kambing Katjang) and four male sheep (Malin) weighing 25-35 kg. Rumen volume, as well as rumen fluid dilution rate were also determined. The animals were housed in single pens with individual feeding and drinking troughs and each animal was fitted with a rumen fistula. They were fed two diets : chopped rice straw+200 g soybean meal (SBM), and chopped rice straw+190 g soybean meal+300 g sago meal (SBM+SM). Rice straw was offered ad libitum. The supplements were isonitrogenous (80 g crude protein/animal/d), but the proportions of dry matter (DM), organic matter (OM), crude fibre (CF), neutral detergent fibre (NDF) and acid detergent fibre (ADF) were lower in the SBM supplement (191, 165, 11, 40, 15 g/animal/d for DM, OM, CF, NDF and ADF, respectively) than in the SBM+SM supplement (445, 423, 25, 102, 38 g/animal/d for DM, OM, CF, NDF and ADF, respectively). Two animals from each species were fed either supplement in a cross-over design in two periods. Each period lasted for four weeks. In situ and in vivo digestibility studies were carried out, followed by the determination of rumen volume and rumen fluid dilution rate. The results showed that straw DM and total DM intakes of goats (average of $48.7g/kg\;W^{0.75}$, $72.7g/kg\;W^{0.75}$, respectively) were significantly (p<0.01) higher than sheep (average of $3.56g/kg\;W^{0.75}$, $61.6g/kg\;W^{0.75}$, respectively), but OM, N and GE intakes were not significantly different between the two animal species. When the effect of supplements was compared, animals fed SBM+SM supplement had significantly (p<0.001) higher DM, OM and GE intakes than animals fed SBM supplement. Potential degradabilities of rice straw DM were significantly (p<0.01) higher in goats (average of 48.8%) than in sheep (average of 46.1 %). The supplements had no significant effect on the potential degradabilities of DM, OM and NDF, but they had a significant (p<0.05) effect on the degradation rates of DM and NDF. The addition of sago meal in the diet reduced the degradation rates of DM and NDF of rice straw in the rumen. Potential degradability of DM of soybean meal was not significantly different between animal species as well as between supplements. Sago meal was highly degradable. At 24 h of incubation in the rumen, 90-95% of DM loss was observed. There was a significant interaction between animal species and supplements in the in vivo digestibility of ADF and GE. In animals fed SBM supplement, the in vivo digestibility of ADF was significantly (p<0.05) higher in goats ($50.6{\pm}4.22%$) than in sheep ($44.4{\pm}3.21%$), but digestibility of GE was significantly (p<0.05) higher in sheep ($70.2{\pm}1.93%$) than in goats ($63.0{\pm}3.07%$). The digestibility values of CP and OM were significantly (p<0.05) higher in sheep when compared to goats. Animals fed SBM+SM supplement showed significantly (p<0.05) higher DM and OM digestibility values than animals fed SBM supplement, but digestibility values of CP were significantly (p<0.05) higher in animals fed SBM supplement. Differences in in vivo digestibility values of CF and NDF were not significantly different between animal species or supplements. Water intake, rumen volume ($1/kg\;W^{0.75}$), rumen fluid dilution rate and mean retention time were similar between the two animal species. However, rumen fluid dilution rate and mean retention time was significantly (p<0.01) affected by supplements. Animals fed SBM+SM had faster rumen fluid dilution rate and consequently shorter mean retention time.

Every year the number of the elderly increases in Korea thanks to the improvemen of social and economical levels and the development of medicine. However, many problems such as insufficent care and the isolation of the elderly have been commonplace. This trend exists not only because of increased lifespan but also the changing social structure of the nuclear family. Accordingly, inspite of the development of medicine, geriatric diseases including circulatory diseases are increasing in proportion of elderly population, as well as the severity. Therefore, it is important to emphasize that health care programs provide the best possible health care and functional capacities in terms of healthy elderly lifestyles. Especially, the phenomena of aging and geriatric diseases taking place with the elderly naturally are affected by lifestyle and the drastic changes in exercise patterns. This study aims to improve geriatric health by introducing a rhythmic movement program for the elderly to estabilish a health-promoting self-care system and by developing quality of life, perceived health status, their physical and physiological functions and emotional state. The theoretical framework used in this dissertation is derived from the Health-Promoting Self-Care System Model (Simmons, 1990), which integrates the Self-Care Deficit Nursing Theory (Orem, 1985), the interaction model of Client Health Behavior (Cox, 1982) and the Health Promotion Model (Pender, 1987). As a quasi-experimental design, the nonequivalent control group pretest-posttest design is utilized for this study. The subjects of this study consist of 64 people, over 65 years old who live in 2 nursing homes for the aged located in S city , Kyong-gi province and volunteered for this study from July, 12, 1999 to September, 17, 1999. They are divided into two groups：33 in the experimental group and 31 in the control group. The experimental group particpated in the Rhythmic Movement Program at the nursing home, which was comprised of 45 minutes a session, 5 sessions a week during 9 weeks. In order to measure the results of the Rhythmic Movement Program, aspects of perceived health status, balance, flexibility, grip strength, leg strength, heart rate, blood pressure, depression, anxiety and the quality of life were measured before and after participating in the Rhythimic Movement Program for the experimental group after 9 weeks, as well as the control group. The collected data were processed by SPSS PC+ and analyzed by the X2 test, t-test, ANCOVA and the Pearson Correlation Coefficient. The results of this study are as follows: 1. The perceived health status conditions in the experimental group show statistically significant improvement when compared to the control group (F=17.51, p=.000). 2. The physical and physiological functions, that is, balance (F=17.51, p=.000), flexibility (F=8.01, p=.006), grip strength (F=3.21, p=.018) and leg strength (F=25.78, p=.000) in the experimental group are higher than the control group. The vital signs, that is, the number of heart rate (F=.022, p=.884), systolic pressure (F=1.73 p=.193), and diastolic pressure (F=2.74, p=.103) in the experimental group compared to the control group decreased, but doesn't show statistically significant differences. Immune responses (F=5.13, p=.003) showed statistically significant increases in the experimental group when compared to the control group. 3. The emotional state are improved, that is, degree of depression (F=11.56, p=.001) and degree of anxiety (F=9.14, p=.004) in the experimental group showed statistically significant decreases. 4. The quality of life in the experimental group (F=3.03, p=.037) showed statistically significant differences compared to the control group. 5. The observations of the relationships among the perceived health status, emotional state , the quality of life, the relationships between the perceived health status, the degree of depression (r=-.653, p=.000) and the degree of anxiety (r=-.786, p=.000) were in contrary propotions, while the relationships between the perceived health status and the quality of life (r=.234, p=.008) were in direct propotion. In conclusion, the Rhythmic Movement Program used in this study for geriatric nursing care is simple and safe for application to the elderly and shows significant effects by implementing 5 sessions a week for 9 weeks. The Rhythmic Movement Program improves the quality of life, maintains as well as improves the physical and physiological fuctions and emotional state, therefore this program is strongly recommended for positive applications for independant geriatric nursing health care.
