This is the descriptive investigation study intended to provide basic informations to develop concrete method of nurse arbitration which can improve the quality of nursing care on family by investigating and analyzing the perception and practice on family nursing of clinical nurse. 332 nurses working in 4 university hospitals in Seoul have been the object and the collection of data have been conducted by visiting cooperated by the department of nursing in university hospital from April 4th through April 17th 1998. The measuring instrument of the perception and the practice on family nursing which was written by the researcher was used based on the family nursing arbitration by recently amending Calgary Family Arbitration of the Model of Wright & Leahey. Cronbach's a value of this instrument was .9288 in the perception and .9168 in the practice the collected data have been analyzed by frequency percentage, averaged value. t-test, F-test(ANOVA), Duncan's Multiple Range, Pearson's Correlation Coefficient, and the results are as the follows: 1. The perception on patient's family nursing of clinical nurse showed comparatively high by 3.22 in average(maximum 3.52, minimum 2.82) on the basis of 4 point but the practice showed low by average 2.47(maximum 3.02, minimum 2.11), By providing the patients and their family with "The information about the health problem of the which is the role of giving explanation and information about the disease. the nurse presents the method of their helping patient and in case that the family lack of knowledge about the health problem and crisis of the patient which is the role of education about the method of solving the crisis and change. the nurse educates about the necessity and method of taking care of the crisis and the changes. The third question that the relation of recognizing the difficuly of family and cooperating with them in supporting the patient for mutual function is to be formed showed high in the degree of perception and practice of the necessity. 2. General characteristics of perception about patient's family nursing of the object showed no significant difference except the concerns about the family usually(F=5.472. p<.001) and general characteristics which showed significant difference in the degree of practice were educational background (F=3.177, p<.05), clinical experience (F=2.462, p<.05) and position(F=7.029. p<.001), and attention about patient's family(F=10.603, p<.001), 3. The relation between perception and practice about the nursing on patient's family showed pure correlation but the degree was very low(r=.188, p<.05). The above results showed that the clinical nurses has been high understanding about the necessity of patient's family nursing but the degree of practice has been very low due to the lack of education about the family nursing, having no ways of nurse arbitration for practical duty and lack of political administrative support. Therefore concrete and systematic family situation and arbitration method to be applied clinically are required to be developed and also the education about patient's family nursing and the development of the course for clinical practice are required and political and administrative support for clinical practice about patient's family nursing is required as well.

The storage of rice polishing (RP) with and without addition of antioxidant for sixteen weeks and its effect on rancidity and metabolizable energy values during the summer season was determined. Fifteen Single Comb White Leghorn cockerels of approximately uniform age and weight were procured and kept in metabolic cages under standard feeding and management practices. Five force feeding trials were conducted. In the first trial, fresh RP with 0 weeks of storage (diet 1 and 2) was used followed by four feeding trials with 4 (diet 3, 4), 8 (diet 5, 6), 12 (diet 7, 8), and 16 (diet 9, 10) weeks of storage of RP. The same birds were used in all trails. The birds were fasted for a period of 21 h, followed by force feeding of 20 g of RP with and without antioxidant for all storage periods. The control/fasting group was also maintained to measure endogenous fecal losses. Excreta were collected after 48 h for the determination of AME and TME values of RP. Along with the biological trials, laboratory assay of the RP stored with and without antioxidant was conducted to measure the extent of rancidity in terms of Thiobarbituric acid value (TBA). The TBA values were affected (p<0.05) by storage period and the values increased when the storage period increased from 4 to 16 weeks. However, the TBA values were significantly reduced (p<0.05) when RP was stored after addition of antioxidant when compared with the values obtained from RP stored without antioxidant (diet 3 vs. 4, 5 vs. 6, 7 vs. 8, and 9 vs. 10). The AME MJ/kg and TME MJ/kg values of RP were neither affected by increase in storage period nor addition of antioxidant. The findings of this study revealed that there was no effect of rancidity and storage time on the nutritive value, AME or TME of RP in poultry. However, TBA values were increased with the increase in storage period.

Mitochondrial genomes have been extensively studied for phylogenetic purposes and to investigate intra- and interspecific genetic variations. In recent years, numerous groups have undertaken sequencing of platyhelminth mitochondrial genomes. Haplorchis taichui (family Heterophyidae) is a trematode that infects humans and animals mainly in Asia, including the Mekong River basin. We sequenced and determined the organization of the complete mitochondrial genome of H. taichui. The mitochondrial genome is 15,130 bp long, containing 12 protein-coding genes, 2 ribosomal RNAs (rRNAs, a small and a large subunit), and 22 transfer RNAs (tRNAs). Like other trematodes, it does not encode the atp8 gene. All genes are transcribed from the same strand. The ATG initiation codon is used for 9 protein-coding genes, and GTG for the remaining 3 (nad1, nad4, and nad5). The mitochondrial genome of H. taichui has a single long non-coding region between trnE and trnG. H. taichui has evolved as being more closely related to Opisthorchiidae than other trematode groups with maximal support in the phylogenetic analysis. Our results could provide a resource for the comparative mitochondrial genome analysis of trematodes, and may yield genetic markers for molecular epidemiological investigations into intestinal flukes.

Purpose: This study was conducted to explore the relationship among health belief. health locus of control and patients sick-role behavior compliance of diabetic mellitus patients visiting public health center. Method: The subjects of this study were 193 of the diabetic patients who were visiting 4 Public Health Center in B city. The instrument used for measuring health belief was Park's(1985). for health locus of control was Wallston. et al's(1978) and for sick-role behavior compliance was Park's(1984). The data were collected with structured questionnaires; total 58 items contained about health belief. health locus of control and sick-role behavior compliance from 1st to 31st July. 2001. The data was analyzed by the SPSS/PC programs using t-test. Pearson's correlation coefficient. ANOVA and Scheffe-test. Result: The average score of the health belief was $57.99\pm9.45$ health locus of control was $66.83\pm9.48$ and sick-role behavior compliance was $42.81\pm7.00$. Statistically significant factors influencing the health belief among social demographic characteristics were family number(F=3.818. p=0.024), monthly income(F=5.153, p=0.002), time of diagnosis(F=3.937. p=0.002) and difficult to control disease(F=5.803. p=0.000). The significant factors influencing the health locus of control were marital status(F=4.669. p=0.010). Also significant factors influencing the sick-role behavior compliance were monthly incomes(F=5.245, p=0.000). the time of diagnosis(F=4.424. p=0.001) and admission to hospital with diabetes(F=9.031. p=0.000). There was negative mild correlation comparatively between health belief and sickrole behavior compliance(r=-0.142, p<0.05) but no correlation in sensitiveness/severity, barrier, benefit(p<0.05). There was no correlation between internal. external. chance health locus of control and sick-role behavior compliance (P>0.05). Conclusion: There was a negative weak relationship between health locus of control and patient's sick role behavior compliance. Therefore further study to investigate the relating factor of the sick role behavior compliance among above of middle aged diabetes mellitus patients is necessary.

Due to the common dietary practice of preparing foods in various ways using the same food item, in addition to rather a large number of food items that average Koreans consume, it is difficult to accurately assess the nutritional adequacy. In an effort to identify a reliable means of assessing the nutritional adequacy of Korean adults, we analyzed the association between the scores of dietary diversity (DDS) and dietary variety (DVS), and the quality of nutrient intake as assessed by Nutrient Adequacy Ratio (NAR) and Mean Adequacy Ratio (MAR). A three day-dietary record was obtained from each of 324 inhabitants, aged 40 to 69 years (mean :t SD,52.4 $\pm$ 8.7), of a rural area (Ansung) and a mid-sized city (Ansan) of Korea. These individuals were randomly selected among the participants of the Korean Health and Genome Study. The number of consumed foods and food groups were assesses by DDS (scored 1 to 5) and DVS (ranked 30 $\leq$,31 - 40, 41 - 50, 51 - 60, and 60 <) over three-day period, respectively. As DDS/DVS increased, mean daily food intakes tended to increase, and NARIMAR was improved. Thus, DDS and DVS were significantly correlated with the quality of nutrient intake. Over 95% of the subjects scored less than 2 in DDS for the first one-day period, whilst over 62% recorded 4 during the full three-day period (p < .0001). The mean number of consumed food items increased from 24.9 to 44.4 as a function of days of the record period (p < .0001). We also analyzed the association of DDS and DVS with MAR, using regression analysis, controlling age and sex as covariates. For DDS, the adjusted coefficient determination (adj $R^2$) values were 8.7%,15.8%,23.3% of MAR, also increasing as a function of the record duration, whereas they were 27.3%, 33.3%, 37.6% for DVS, respectively, demonstrating that NAR/MAR has a better correlation with DVS than DDS. Our data show that DDS, and DVS in particular, are useful parameters for evaluating nutrient intake in the Korean population. Our data also support that one day-dietary records are by no means adequate for accurately describing a wide variety of food choices offered for average Koreans, and that dietary assessment at least for 3 days or longer should be obtained for a reliable evaluation of dietary quality using DDS or DVS.

To investigate the relationship between leaf growth of several woody plants and ait tempera ture in early growing season (from April to June) in deciduous forests, I surveyed the changes of leaf area (LA), leaf weight (LW) and specific leaf area (SLA) of 19 specles, in two areas Namhansansung (NA) and Taegwallyong (TA) area in which that the latitudes are similer ($37^{\circ}28'N$ at NA and $37^{\circ}27'N$ an TA), but annual mean-temperatures were different ($11.8^{\circ}C\;in\;NA, \;6.3^{\circ}C$ in TA) for two years, 1991 and 1992. In the same species, the plants of NA began to grow 10-25 days earlier than those of TA, but the latter grew faster than the former. On 10 June the values of LA and LW per leaf were similar in the two areas but the maximum values of SLA were higher in NA. In the same plant, the values of LA and LW were constant year by year, except for PYIOLUS leveilleana, Quercus mongolica, Symplocos chznensis for. pilosa and S t y a r ubussiu. In N A , the leaves be gan to grow during the first ten days of April, and eariler in 1992 than in 1991, and daily mean temperature (DMT) of the former from 27 March to 6 April were higher than those of thc latter. But the LA increased faster in 1991 than in 1992. and DMT from 10 April to 16 April were higher in 1991 than in 1992.

The purpose of this investigation was to evaluate on the biodegradability, biocompatibility and tissue regenerative capacity of synthetic bioabsorbable membranes in beagle dogs. For animal study, 9 adult beagle dogs were used to examination, on the surgical implantation of membranes and histological analysis. In each animal, the 3rd and 4th premolars of the both sides of the mandible were selected as test teeth. Two types of bioresorbable membranes including "Guidor membrane", "S-membranes" were used to examining for biological activity, and also Gore-tex membranes was used for positive control. Surgically created defects were made in 2 premolars of both sides of the mandible at $3{\times}4mm^2$ in size and tested membranes were implanted in the defected area. A plaque control regimen was instituted with daily tooth brushing with a 0.1% chlorhexidine digluconate during experimental periods. All the experimental animals were sacrificed after 2, 4, and 8 weeks from surgery and undecalcified slides were prepared using the "sawing and grinding" technique described by Donath and Breuner". In biodegradability, all the membranes were started their biodegradation from two weeks after implantation and gradually demolished of their frame morphology from eight weeks. However, demolition of membranes in 8 weeks after implantation was highest in Guidor membranes and followed by S-membranes. Biocompatibilityof two kinds of biodegradable membranes including Guidor and S-mambrane were shown to be well tolerated to the surrounding tissue, and were minimal accumulation of inflammatory cell infiltration around the implanted membranes to compare with Gore-tex membrane. Regeneration of defected alveolar bone was initiated from two weeks of membrane implantation and new bone formation was gradually increased from that time. However, pattern of new bone formation on the defected areas of two kinds of biodegrable membranes was almost similar and quite competitive comparing with Gore-tex membrane. These results implicate that bioresorbable membranes should be highly useful tool for guided tissue regeneration of periodontal defects.

Methanol extracts of aquatic plants were analyzed for allelopathic activities against Escherichia coli JM109 and $Microcystis$ $aeruginosa$ UTEX2385 which were compared to its 2,2-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities. The radical scavenging activities were detected from the extracts of $Persicaria$ $thunbergii$, $Persicaria$ $amphibia$, $Trapa$ $japonica$, $Myriophyllum$ $spicatum$, and $Brasenia$ $schreberi$. Also, the inhibitory activities against cyanobacteria were analyzed according to the order of $B.$ $schreberi$, $T.$ $japonica$, $P.$ $amphibia$, and $M.$ $spicatum$. Most of the extracts from aquatic plants did not show any inhibition against $E.$ $coli$ except $B.$ $schreberi$. We found a positive correlation between the antioxidental activities of methanol extract of aquatic plants and the growth inhibitory activities for cyanobacteria in terms of the DPPH radical scavenging activities ($R^2$=0.381, $P$ <0.0001). The inhibitory activities of methanol extract against $E.$ $coli$ growth was not correlated with the other activities of aquatic plants ($P$ >0.04). We suggest from this study that the allelopathic effects of aquatic plants against cyanobacteria could be screened by using the bioassay based on DPPH.

The purpose of the study are to examine the perception of the importance and performance of patient education of the clinical nurse and find out the interfering factors in practicing patient education. The data were collected from convenient sample of 256 clinical nurses working in the nursing units of adult patients except the psychiatric unit, obstetric unit, dental surgical unit and intensive care unit of one University Hospital in Seoul from September 29 to October 2, 1998. Three measurement tools of self-report- questionnaires developed by researcher used. For the content validity of the questionnaires, two sessions of panel discussion and a pilot test were done and finally factor analysis was done with Varimax method. Analysis of data was done with SAS program using frequency, percentage, means, standard deviation, Pearson's Correlation Coefficients, t-test and ANOVA. The obtained results were as follows : 1. The surveyed nurses perceived the importance of patient education at higher level with mean score of 4.08 among 5 point than their perception of practice( mean score : 3.42). 2. There was positive significant correlation(r=.29, p=0.0001)between nurses' perception of the importance of patient education and it's practice 3. Among the teaching contents for patients, 'information of diagnostic procedure and operation' and 'orientation of hospitalization' were perceived most important. And 'preparation for discharge' and 'understanding of disease and health promotion' were perceived least important 4. Among the teaching contents for patients, 'orientation of hospitalization' and 'information of diagnostic procedure and operation' were perceived highly performable. And 'understanding of disease and health promotion' and 'preparation for discharge' were perceived least performable. 5. Three types of interfering factors were identified as patient-factor, situational factor, nurse-factor. The mean degree of impediment with the interfering factors was at average level(3.09 among 5). The patient and situational factors of impediments were more interfering than nurse- factor for teaching patients. 6. In older age(p<.05), married state (p<.05), higher educational status (p<.01), higher clinical experience (p<.01) and higher position(p<.01), the score of perceived importance of patients education was more high. 7. In older age(p<.01), higher clinical experience(p<.001) and surgical unit (p<.01), the score of perceived performance of patients education was more high. In conclusion, in order to activate patient education practice in the clinical setting, the continuing education for patients education should be more emphasized and the effective teaching methods and materials should be developed to help patient teaching. And an organizational support such as budgeting for patient education and reimbursement system should be administrated.
