Purpose: The purpose of this study is to explore college women's views of women for forming an upright sex role identity and sex values. Method: The data were collected through in-depth interviews of 10 college women on Jeju Island from February 2002 to March 2002. The interviews were conducted by the writer of this thesis. Each interview lasted for about 45 minutes. The data were analyzed by the Giorgi method. Result: Five main meanings were identified: 1) unfairness 2) majesty 3) mothering 4) womenishness 5) backward in capacity. In other words, women's roles are to look after their family and to take care of household affairs. Women should be beautiful and have womenish traits. Women are less intelligent than men. Women are dependent on men though they suffer from unfairness. This study presents an evidence that the traditional sex-role attitudes still prevail. Conclusion: In order to form an upright sex role identity and sex values, institutional programs in the society and individual efforts are needed.

A cultural model can change as times go by within one ethnic group. For example, a strong familism has existed for a long time throughout a history of Korea, but it is, just like most social values, now in the midst of a rapid change. Accordingly, Koreans' belief about family values and responsibility for supporting their old parents are changing, too. Especially, supporting parents was one of the highly-estimated traditional values, but it seems to no longer exist. However, one's own rearing experience might be a moderator of association of his or her familism with the ebbing value. Therefore, we aim to address the following research question: What is the relations among college student's familism, their own rearing experiences, and their beliefs about supporting old parents. A total of 155 college students participated in this study. Data were analyzed by SPSS. T-test and ANOVA were used for data analysis. The findings are that college students' beliefs in supporting parents are significantly influenced by their familism and rearing experiences: Those with a strong familism and warm rearing experience have solid beliefs in supporting parents.

We researched the modern meanings of traditional dining table courtesy education and its correlation with the main values of contemporary personality education based on dining table courtesy education stated in the social norms texts of the Joseon dynasty. Among the social norms of the Joseon dynasty, we chose Sohak, Naehun, Dongmongsuji, Seonghakjibyo, Gyeongmongyogyeol, Jeungbosallimgyeongje, Sasojeol, and Koamgahoon for research. As a result of our research on these documents and books, the modern meanings of the courtesy education at the dining table can be summarized as follow. First, the courtesy education has table manners appropriate for the development level of early children. Second, it teaches right-handed dining manners that match the features of Korean food culture. Third, it has the self-discipline and the values of community life, sharing, solicitude, and communication. Fourth, parents and grandparents are involved in the education. Fifth, it has the core values of modern personality education: manners, filial piety, respect, solicitude, communication, cooperation, and responsibility. Future courtesy education at the dining table should include practical education programs that can consolidate the bond of sympathy between the home, school, and society, and can improve its practice; in addition, to expand the opportunities for education, proactive social support is demanded.

The ionization of tyrosine residue is known to be involved in the stabilization of transition-state in catalysis of astacin based upon the astacin-transition state analog structure. Two tyrosine residues, Tyr-216 and Tyr-219, are conserved in all MMPs related with astacin family, We replaced Tyr-216 and Tyr-219 into phenylalanine, respectively and the zinc binding properties, kinetic parameters, and pH dependence of each mutant are determined in order to examine the role of tyrosine residue in matrilysin catalysis. Both mutants contain two zinc atoms per mol of enzyme, indicating that either tyrosime does not affect the zinc binding property of the enzyme. Y216F and Y219F mutants are highly active and the kcat/Km values are only decreased 1.1-1.5-fold compared to the wild-type enzyme. The decrease in the activity of the mutants is essentially due to the increase in Km value. The pH dependencies of the kcat/Km values for both mutants are similar to the corresponding dependencies obtained with the wild type enzyme. The pKa values at the alkaline side of both mutants are not changed. These kinetic and pH dependence results indicate that the ionization of active site tyrosine residue of matrilysin is not reflected in the kinetics of peptide hydrolysin as catalyzed by astacin.

In order to examine the changes in the appearance properties and the post-adhesion appearance properties of Hanji yarn blended fabrics : 100% Hanji yarn fabric, two kinds of cotton / Hanji yarn blended fabrics and 100% cotton fabric, were selected and fused with three kinds of interlinings. After fusing, changes of standardized KES values were examined. 1. W/T, B/W of Hanji yarn blended fabrics was higher than that cotton fabric. WC/W, 2HB/W, 2HB/B, and 2HG/G values of Hanji yarn blended fabrics are lower than cotton fabric. This means that the Hanji yarn was mixed, shape retention, wrinkle recovery was improved, and the drape property was lowered. 2. After fusing, W/T, shape retention, wrinkle recovery of Hanji yarn blended fabrics increased, and WC/W values of Hanji yarn blended fabrics decreased. The wrinkle recovery property of Hanji yarn blended fabrics were improved; however, the 2HG/G value of Hanji yarn fabric increased due to fusing, and the wrinkle recovery property of Hanji yarn fabric decreased. 3. In the selection of adhesive core, I1 adhesive core is excellent in terms of shape stability and wrinkle recovery; however, an I3 adhesive core is recommended for drape and silhouette formation. When the fabric of the adhesive core was PET, it was found to penetrate better between the fabrics during adhesion than the case of cotton fabrics.

The objective of this study was to investigate the physicochemical and microbiological characteristics of round of Hanwoo by vacuum packaging film materials, polyvinylidene chloride (PVDC) and ethylene vinyl alcohol (EVOH). The packaged beef samples were stored in refrigerated conditions (2±1℃) for 12 weeks. Physicochemical analysis with pH, surface color, thiobarbituric acid reactive substances (TBARS) values, and volatile basic nitrogen (VBN) values and microbiological analysis with aerobic plate count (APC) and metagenomic analysis of packaged beef samples were performed. The pH and surface color did not change substantially during the 12 weeks and EVOH-packaged beef tended to be lower than those of PVDC-packaged beef. PVDC- and EVOH-packaged samples showed low TBARS and VBN values below standard limits. APC did not exceed 7 Log CFU/g for both samples during storage. In metagenomic analysis, Firmicutes and Lactobacillaceae were dominant phylum and family of the PVDC- and EVOH-packaged beef. In both packaged samples, Dellaglioa algida was the dominant species during storage, with the notable difference being the presence of Lactococcus piscium. Therefore, this study provided the information on the quality of vacuum-packaged beef according to different vacuum films for long-term refrigerated storage.

Every patient, who enters the hospital has a potential for becoming anxious. The control of hospitalization anxiety experienced by hospital patients is considered to be an important factor in the process of recovery from illness. This study was conducted to investigate the relationship between informativeness and hospitalization anxiety in order to give basic data for psycho-social aspect of nursing care for hospitalized patients. One hundred patients admitted to Kyungpook National University Hospital during the period of Jan. to June 1975 were sampled and divided into two groups; fifty of experimental and fifty of control group. The set of informations prepared by the investigator were given additionally to experimental group while the control group only received routine informations. Both groups were rated according to the Hospitalization Informativeness Scale which consisted of 24 questionaries and 4 categories and Hospitalization Anxiety Scale one or two days prior to discharge from the hospital. The results of the study were as follows; 1 . Mean values of Hospitalization Informativeness Scale revealed significant differences at 0.01 level with experimental group showing higher mean value. Age, sex ana educational states aid not influence the mean values of Hospitalization Informativeness Scale in both groups. 2 . The length of hospitalization did not influence significantly on the mean value of Hospitalization Informativeness Scale in both groups. 3. Rank difference correlation coefficiently between mean value of Hospitalization Informativeness Scale and the importance of information the patient's perceived were revealed significant at 0.01 level in all 4 categories such as admission discharge, treatment and nursing activities, diagnostic test, diagnosis and prognosis, health teaching for the patient and family in experimental group. While, only two categories such as treatment and nursing activities and health teaching for the patient and family in control group were revealed significant correlation. 4. Mean value of Hospitalization Anxiety Scale revealed significant difference at 0.05 level with the experimental group showing lower Hospitalization Anxiety Scale. 5. Correlation coefficiently between Hospitalization Informativeness Scale and Hospitalization Anxiety Scale were revealed significant at 0.01 level in experimental group but there was no significant correlation in control group.

Resveratrol is known to have potent cancer chemopreventive activity against tumorigenesis caused by 7,12-dimetylbenz［$\alpha$］anthracene(DMBA) which is known to be oxidized to reactive products by cytochrome P450 1B1 (CYP1B1). The effects of resveratrol on the activity of recombinant human P450 1 family enzymes, expressed in Escherichia coli membranes with human NADPH-P450 reductase, were determined by measuring alkoxyresorufin O-dealkylation activity, e.g., ethoxyresorufin O-deethylation (EROD) CYP1A1, methoxyresorufin O-demethylation (MROD), CYP1A2, benzyloxyresorufin-O-debenzylation (BROD), CTP1B1. Resveratrol inhibited CYP1B1 and CYP1A1 activities in a dose-dependent manner with $IC_{50}$/ values of 59 and 10$\mu$M for EROD activity and 1.8 and 30$\mu$M for BROD activity, respectively. Resveratrol had only weak inhibitory effect on CYP1A2 activity ($IC_{50}$/ values of 0.44 mM for EROD and ＞2 mM for MROD). Furthermore, resveratrol did not affect NADPH-P450 reductase activity significantly. Resveratrol inhibited the CYP1B1-dependent EROD activity with a $K_{i}$ of 28 $\mu$M in a non-competitive type manner. these results suggest that resveratrol-derived inhibited of CYP1B1 and CYP1A1 activities may contribute to the suppression of DMBA inducible tumorigenesis observed in extrahepatic tissues.s.
