  • The purpose of this study is to determine whether the NCASA (Nursing Child Assessment Sleep/Activity Record) would be suitable to evaluate and to provide the basic resources for a Korean model of sleep/activity patterns during the first 6 months Korean infants' lives and to provide a basis for nursing intervention for mothers of early infants. The subjects of this study were 94 normal infants from birth to 6 months of age who visited the postpartum care center and two general hospitals located in Pusan from February 1 to April 28, 2000. The method of data collection was through convenient sampling. The instrument of this study was the NCASA translated by the Korean parent Child Health Academic Association. The collected data were analysed by mean, standard deviation, frequency percentage and ANOVA, Post Hoc test by use of SPSS/PC. The conclusions obtained from this study are summarized as follows: 1. The mean amount of daytime sleep was 8.06 hours. The mean amount of nighttime sleep was 6.31 hours. The mean amount of total daily sleep was 14.37 hours. The mean of the longest sleep period was 5.20 hours. The mean regularity of daytime sleep was 25.84%. The mean regularity of nighttime sleep was 77.69%. The mean regularity of total daily sleep was 42.60%. The mean frequency of nighttime wakenings was 2.33 times. 2. The mean amount of daytime activity was 8.25 hours. The mean amount of nighttime activity was 1.39 hours. The mean amount of daily total activity was 9.64 hours. The mean of the longest activity period was 3.80 hours The mean frequency of daytime feeding was 5.69 times. The mean frequency of nighttime feeding was 2.08 times. The mean frequency of total daily feeding was 7.74 times. The mean frequency regularity of feeding was 54.62%. The mean frequency of wakenings was 5.14 times. The mean frequency of crying was 1.90 times. 3. According to an analysis of sleep patterns based on an infant's age, there were some significant differences in the following factors: amount of daytime sleep(p<.001), amount of night time sleep(p<.05), amount of total daily sleep (p<.001), longest sleep period(p<.001), regularity of daytime sleep(p<.001), regularity of nighttime sleep(p<.01), regularity of total daily sleep(p<.001), frequency of nighttime wakenings(p<.001). 4. According to an analysis of activity patterns based on an infant's age, there were some significant differences in the following factors: amount of daytime activity(p<.001), amount of nighttime activity(p<.01), amount of total daily activity(p<.001), longest activity period(p<.05), frequency of nighttime feeding(p<.01), frequency of wakenings(p<.001). 5. The mean amount of a mother's day time was 16.30 hours. The mean amount of a mother's night time was 7.70 hours. In conclusion, the initial irregular sleeping and activity patterns of the early infant became regurized as the infant grew older and estabilished firmer patterns of sleeping and of activity.

  • 조석에 의한 지하수위변동이 발생하는 해안가 암반대수층에서 고조(high tide)과 저조(low tide) 조건에서의 차이를 규명하기 위한 양수시험이 수행되었다. 본 연구에서 양수시험이 수행된 시험대 수층은 암반층으로서 시험공들은 해안가에서 약 180 m 이격되어 있으며, 양수정(MW1공)과 관측정(MW2공)의 이격거리는 8.05 m 이다. 양수정과 관측정 모두 공 내경은 0.205 m 이며, 케이싱심도는 지표면하 19 m 정도이다. 그리고, 양수정과 관측정의 지하수위는 지표면하 5 m 정도에 형성 되어 있으며, 시험대수층의 두께는 약 40 m 정도이다. 양수시험은 총 3회 수행되었으며, 모든 시험에서 수중모터 설치심도는 지표면하 30 m 이고 양수율은 $75\;m^3/day$로서 동일하였다. 그러나, 양수시작 시간의 차이를 두어 고조 후 1회(1차 시험), 저조 후 2회(2차 및 3차 시험) 수행되었다. 양수정과 관측정에서 자동수위측정기(Model 3001, Solinst)를 설치하여 관측된 지하수위변동 자료에 의하면, 조석현상 발생 후 시험공 내 지하수위변동 경과시간은 고조(high tide) 후 2시간, 저조 (low tide) 후 1시간 정도인 것으로 나타났다. 따라서, 양수시험 시 1차 시험은 고조 후 2시간 경과한 시점에서, 2차 및 3차 시험은 저조 후 1시간 경과한 시점에서 양수가 시작되었다. 양수시험에 의한 경과시간에 따른 수위강하량 그래프에서는 고조조건이 저조조건에 비해 수위강하량이 더 적은 것으로 나타났다. 이러한 원인은 저조에 비해 고조 조건에서는 해수에 의한 지하수위가 상승하여, 동일한 양수조건에서 수위강하량이 적게 나타난 것이다. 양수시험 자료가 AQTESOLV 3.5 프로그램을 이용하여 해석되었다. Theis method에 의해 산정된 수리전도도는 고조 조건의 양수시험에서는 $4.159{\times}10^{-6}\;m/sec$, 저조 후에서는 각각 $3.818{\times}10^{-6}\;m/sec$$3.926{\times}10^{-6}\;m/sec$ 이었다. 저조 후에 비해 고조 후의 수리전도도가 5% 이상 높은 것으로 산정되었다. 이상의 연구 결과들에 의해, 해안가 암반대수층에서는 양수시험 시 조석효과에 의한 수리적인 변동을 고려한 설계와 해석이 수행되어야함을 확인할 수 있었다.

  • To improve the effectiveness and efficiency of public health personnel training, we evaluated not only how appropriate the students felt the objectives, contents, methods and multimedia used in the train ing courses, but also how much the students accomplished the objectives and applied skill and knowledge to their own works. We selected 5 courses for the study : Tuberculosis control, Radiological technique, Public health information, Immunization, Mental health management courses used by Kirkpatrick's evaluation model. Reaction evaluation was carried out in final day by questionnaire. The results showed that all of them were very satisfied with educational input and curricula, learn Ing environment. Secondly, we measured the degree of learning achievement on pre and post training by questionaire of specific behavioral objectives. The degree of learning achievement was statistically higher just after training than pre training (paired t-test, p<0.01). Thirdly, evaluation of behavioral change to job was conducted to find out how much students applied skill and knowledge to their own job in 3 months after training by questionnaire. The results of behavioral change evaluation showed that 43.5% of the students who were performing job related with the training courses in 3 months after training applied the learned skill and knowledge to their own job quite well and 37.8% of them applied relatively well, therefore total 81.4% of them applied to their own job. And effectiveness of training for the above mentioned students showed that 41.9 % of them had improved or enforced their jobs after training, 35.5% of them had had no remarkable changes, and 15.7% had newly applied the learned skill and knowledge to their jobs. For evaluating the degree of usefulness of material predistribution in two weeks before training, we compared experimental groups with control groups. The results showed that general reactions are helpful but the degree of learning achievement is no discrepancy.

  • Objective: To explore the incidence, clinical characteristics, diagnosis and treatment strategies, prognosis of patients with malignancy-associated hypercalcemia (MAH). Methods: The data of 115 patients with MAH who were treated at the Medical Oncology Department of Chinese PLA General Hospital from Jan., 2001 to Dec., 2010 was retrospectively reviewed. Survival analysis was performed using the Kaplan-Meier method and the Cox proportional hazard model with statistic software SPSS 18.0. Results: The patients had blood calcium levels ranging from 2.77 to 4.87 mmol/L. Except for 9 cases who died or were discharged within 5 days after admission, all other patients recovered to normal blood calcium level after treatment with bisphosphonates or intravenous hydration and diuretics; their survival after occurrence of MAH was from 1 day to 4,051 days, and the median survival time was only 50 days. In the log-rank test, the male, renal metastasis, central nervous system symptoms and hypercalcemia occurring over 140 days after cancer diagnosis were predictors of poor survival (P=0.002, P=0.046, P=0.000, P=0.009). In the COX analysis, being male, central nervous system symptoms and hypercalcemia lasting over 140 days after cancer diagnosis were independent prognostic factors for survival time (RR=2.131, P=0.027; RR=3.054, P=0.002; RR=2.403, P=0.001). According to these factors, a score system was established to predict the patient prognosis and adjust the treatment. Conclusion: Cancer patients with MAH have an extremely poor median survival. Some independent factors indicate poor prognosis, including male gender, central nervous system symptoms and hypercalcemia lasting over 140 days after cancer diagnosis. The prognostic score can serve as a reference for MAH prognosis and treatment, worthy of further investigation.

  • This study was conducted to estimate the genetic parameters for common ketosis indicators (${\beta}$-hydroxybutyrate acid, BHBA; milk acetone), feed intake efficiency indicator (energy-corrected milk, ECM), and milk yield (MY) in Korean Holstein. A total of 75,072 monthly test-day records from 14,397 first parity cows were collected, between 2012 and 2016, from Korea animal improvement association enrolled farms. Variance components were estimated using a multiple trait random regression model. The heritability of BHBA and acetone levels ranged from 0.06 to 0.15 at different DIMs. The phenotypic and genetic correlations between BHBA and acetone were between 0.73 and 0.90, and between 0.93 and 0.98, respectively. The phenotypic correlation between BHBA and MY, between acetone and MY, between BHBA and ECM, and between acetone and ECM ranged from -0.18 to -0.05, -0.23 to -0.05, 0 to 0.10, and -0.09 to 0.01, respectively. Genetic correlation estimates between BHBA and MY, between acetone and MY, between BHBA and ECM, and between acetone and ECM also ranged from -0.55 to 0.05, -0.62 to -0.04, -0.10 to 0.11, and -0.20 to 0.00, respectively. We hope that these results would greatly assist in the improvement of ketosis disease in the local Holsteins.

  • A study was conducted to compare the endogenous basal losses of phosphorus (EBLP) in pigs fed diets containing gelatin (GEL) or spray-dried porcine plasma (SDPP) as protein sources and to determine the standardized total tract digestibility (STTD) of phosphorus (P) in SDPP. The trial was carried out at the Federal University of Santa Maria, Brazil. Twelve castrated pigs with an initial body weight of 55 kg were individually allotted in metabolic crates during two 12-day periods, each with 7 days of adaptation and 5 days of total fecal collection. The beginning and the end of the collecting periods were determined according to the marker-to-marker approach, using ferric oxide as an indigestible marker. Pigs were submitted to four semi-purified diets, one being a P-free diet with 30% of GEL as the protein source and three were diets with 10%, 20%, and 30% inclusion of SDPP respectively. Data were subjected to analysis of variance and the model included the effects of period, animal and treatments; the results of the three diets with increased levels of SDPP were subjected to linear regression analysis. The intercept of the relation of between ingested P and absorbed P represented the EBLP, while the slope indicated the STTD of P in SDPP. The EBLP means obtained by P-free diet and regression method were compared with the Student t test. The EBLP were 128.95 mg/kg dry matter intake (DMI) and 153.63 mg/kg DMI (standard error = 77.0; p<0.06) using the P-free diet with GEL as the protein source and the regression method, obtained with diets containing increased levels of SDPP, respectively. The apparent digestibility of P was 87.9%, 94.2%, and 92.9% for the treatments containing 10%, 20%, and 30% inclusion of SDPP, respectively. The estimated STTD of P obtained with the linear regression was 97.4%. When the EBLP estimated by the P-free diet was used to corrected the apparent digestibility of P in diets containing SDPP, the STTD of P in SDPP was 96.9%, 98.8%, and 95.9% for 10%, 20%, and 30% SDPP, respectively. Therefore, it can be concluded that SDPP can replace GEL to estimate the endogenous losses of P. In addition, the STTD of P in SDPP estimated with the P-free diet was 97.2% and it was 97.4% by the regression method, utilizing SDPP.

  • Decision effectiveness depends on type of knowledge within team members generated by decision making process. Thus, organization in accordance with teams' experience and capability ultimately achieve their desired outcome. However, previous research has not addressed a mediating role between different knowledge type in decision making and product competitive advantages(pioneering advantage and product quality superiority). Based on the knowledge-based view, we model how different knowledge characteristics in decision making affect to acquire each of knowledge in decision making effectively and then to apply acquired knowledge in decision making. Anchored in a source-position-performance (SPP) framework (Day and Wensley's, 1988), we shed light on the effects of three knowledge characteristics dimensions in decision making process on knowledge management competences in decision making for a new product project. We also examine the relationship between two dimensions of NPD knowledge management competences, and product competitive advantages which consist of market pioneering advantage and product quality superiority. To test the relationships, the empirical analyses are conducted using a sample of team managers who participated in NPD projects. This study suggest that managers should increase their acquirability and applicability of knowledge by integrating complexity of diverse and new knowledge, developing codifiability of well-documented knowledge, and creating the sharing common knowledge among NPD team members. Thus, they are able to outrun major competitors in terms of pioneering advantage and product quality superiority perspective.

  • l. Backgrounds of Studies Cerebrovascular accident. one of the three major causes of death among audults with cardiopathy and malignancy, has been on the increase in korea while it is on the decrease in European countries and Japan. Types of stroke undergo changes caused by prolongment of life expectancy. and social and economic variety. More patients of ischemic stroke show a tendency to increase now than those of hemorrhagic stroke in the past. Many clinical studies on medical cerebrovascular and oriental stroke of paralysis have been published. but few clinical studies on therapeutics of integrated oriental and western medicine are to be found. So I have made an attempt to study clinical observations and therapeutic responses of ischemic stroke under integrated oriental and western medicine. 2.Methods. Among the patients admitted into the clinic of Joong-Poong, Woo-Suk University Hospital from May 1. 1993 until April 30. 1994 those 56 patients who were diagnosed as ischemic stroke on Computed Tomography(CT) and showed no dubious symptom after examination of coagulation and bleeding time were classified into the following six steps and treated: l)diagnosis 2)emergency treatment 3)basic treatment 4)treatment of risk and provoking factors. and preceeding disease 5)complications and conservative therapy 6)rehabilitation. For a period of basic treatment both herb medication and urokinase therapy were applied at the same time. Intravenous injection has been given at a unit of 300.000 dosage a day as urokinase therapy during basic treatment. If they showed any dubious symptom in glucose tolerance test. fructose 500ml and urokinase 300.000 dosage were mixed and injected. In case of no symptom 5% DW 500ml was mixed with urokinase 300.000 unit. and injected at a speed of 15gtt per minute. 3. Results and Conclusions 1) The level of ambulation has been improved from 42.9% when admitted to 73.2% when discharged in the degree of recovery. The level of severe function disorder has been remarkably decreased from 55.4% when admitted to 19.6% when discharged. 2) The treatment effect on the basis of therapeutic response of clinical and subjective symptom shows as follows: 7.1% Excellent. 35.7% Good. 37.5% Effective. 10.7% Stationary. and 8.9% Aggravated. The total recovery above effective shows 80.3%. Judging from the above results I think it proper to develop the model of better preventing and treating ischemic stroke through effective therapeutic and clinical studies of integrated oriental and western medicine.

  • Ecological momentary assessment (EMA) is a method that captures the current experience and behavior of subjects in real time in a natural environment. The data collected by EMA reveals alterations according to the time and context of experience and action. The Trier Inventory for Chronic Stress (TICS) is a tool that measures momentary stress, and is capable of measuring stress experienced in real life. This study was undertaken to verify the validity and reliability after translating the short form TICS into a Korean version. Totally, 89 police officers working at the police station in the capital participated in this study. The mobile application developed for this study was installed on their smartphones, and data were collected four times a day for seven consecutive days. Confirmatory factor analysis and content validity index (CVI) was applied to test the validity, and concurrent validity was evaluated by correlating with the occupational stress score. The model was validated by confirmatory factor analysis, and we obtained good reliabilities (I-CVI=0.83-1, RMSEA=0.104, SRMR=0.104, CFI=0.948, TLI=0.919, Cronbach's alpha=0.839). Our findings indicate the reliability, and validate use of the Korean tool for measuring momentary stress.

  • Objective: Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) is one of the representative prescriptions for invigoration of vitality and nourishing of the blood. This study was carried out to investigate the effects of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) on hair regrowth and cytokine changes in a shaving model of C57BL6 mice. Method: Five-week-old mice were acclimated for 1 week at a temperature between $21-23^{\circ}C{\acute{E}}$, 40-60% relative humidity, and 12h of a light/dark cycle before beginning of the experiment. There were two groups including normal saline (control) and a positive control of oral intake of Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) extract (sample) in 18 female mice. The test compounds were topically treated once a day over 14 days. The hair regrowth was photographically and histologically determined during the experimental period of 14 days. Revelation of TGF-${\beta}1$ and EGF were also determined using immunohistochemistry. In addition to that, IFN-$\gamma$, IL-4 and IL-10 were determined in serum. Results: Hair regrowth in the sample group was promoted earlier and faster than the control group, as shown by concentrations of hairs and thick-hair ratio in the sample group. TGF-${\beta}1$ was not revealed in either control or sample group. EGF was strongly positive in out root sheath of some thick hair of the sample group. Serum IFN-$\gamma$ was significantly decreased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-4 was significantly increased in the sample group compared with the control group at 7 experimental days. However, it was not significantly decreased at 14 experimental days. Serum IL-10 was decreased in the sample group compared with the control group, but with no real statistical significance. Conclusion: These results suggest that Yikgeebohyul-tang (Yiqib$\check{u}$xu$\grave{e}$-t$\bar{a}$ng) has hair growth promoting activity and it can be used for treatment of alopecia. Also, these effects relate to EGF revelation of hair roots, a decrease in serum IFN-$\gamma$, and an increase of serum IL-4.
