The purpose of this study was to identify the effect of resistance training intensity levels on muscle damaged index and aging-related hormones in obese middle-aged women. Thirty middle-aged women having over 30% of body fat participated in this study. The subjects were assigned into 3 groups on the basis of workout intensity, 50% intensity, 60% intensity, and 70% intensity. After performing three different types of exercise for 12 weeks, the levels of creatine kinase (CK), lactate dehydrogenase (LDH), melatonin, dehydroepiandrosterone-sulphate (DHEA-S), and growth hormone (GH) in all subjects were assessed before and after the program. Muscle damaged index was effectively changed in low exercise intensity group. However, aging-related hormones were effectively changed in high exercise intensity group. DHEA-S and GH were significantly increased in the 70% intensity group than the other groups.

The purpose of this study was to investigate the implications of dietary intake and the level of serum micronutrients (Se, Mn, Cu, Zn), lipid peroxidation, and antioxidant capacity in Korean women with cervical intraepithelial neoplasia (CIN) . From October 2002 to March 2003, 50 patients diagnosed with CIN (confirmed with colposcopy directed biopsy) and 50 patients without any cervical disease as the control group were enrolled in the study at the Department of Gynecology Cancer Center at Samsung Cheil Hospital. Animal fat intake in CIN group was significantly higher than that of the control group, but plant protein intake in the CIN group was significantly lower than that of the Control group. Energy and zink intakes were similar in the two groups. The serum concentration of antioxidant minerals in the CIN group were not significantly different from the control group. The total radical trapping antioxidant potential concentration of plasma was significantly lower in the CIN group (1.12mM) than in the control group (1.25mM) (p<0.05). But MDA (malondialde-hyde) of serum was significantly higher in the CIN group (7.60mM) than in the control group (4.99mM) (p<0.005). The serum selenium concentration of the control group showed significant positive correlation with the MDA level (r=0.311). These findings are suggestive of protective roles for healthy dietary habit including increasing antioxidant nut-rients and decreasing intake of fat.

Purpose: The purpose of this study was to identify the characteristics of anger expression in middle-aged Korean women by categorizing their patterns of expression while considering the complexity and multidimensionality of anger, and by investigating the characteristics relative to the patterns. Methods: The research design was a descriptive design using Q methodology, which is a method of measuring subjectivity. A convenience sample of 42 participants aged 40-60 years and living in the community in Korea was recruited. The PC-QUANL software program (a factor analysis program for the Q technique) was used to analyze the Q-sort data. Results: Four factors were extracted that described different expressions of anger among middle-aged Korean women; these factors explained 50.1% of the total variance. The frames of reference of the four factors were a) direct diversion, b) silent masking with remaining anger, c) self digestion, and d) controlling anger with objectification. Conclusion: In this study has identified patterns and characteristics of anger expression among middle-aged Korean women were identified, which will aid the development of effective anger-management programs for controlling anger in this population. In future studies, it would be helpful to investigate how the patterns of anger expression established herein are associated with specific health problems such as cardiovascular disorder and cancer.

Aloe products are one of the top selling health-functional foods in Korea, however the adequate level of intake to achieve desirable effects are not well understood. The objective of this study was to determine the intestinal uptake and metabolism of physiologically active aloe components using in vitro intestinal absorption model. The Caco-2 cell monolayer and the everted gut sac were incubated with $5-50{\mu}M$ of aloin, aloe-emodin, and aloesin. The basolateral appearance of test compounds and their glucuronosyl or sulfated forms were quantified using HPLC. The % absorption of aloin, aloe-emodin, and aloesin was ranged from 5.51% to 6.60%, 6.60% to 11.32%, and 7.61% to 13.64%, respectively. Up to 18.15%, 18.18%, and 38.86% of aloin, aloe-emodin, and aloesin, respectively, was absorbed as glucuronidated or sulfated form. These results suggest that a significant amount is transformed during absorption. The absorption rate of test compounds except aloesin was similar in two models; more aloesin was absorbed in the everted gut sac than in the Caco-2 monolayer. These results provide information to establish adequate intake level of aloe supplements to maintain effective plasma level.

This experiment was to find out the complacency of wearing dentures and the linkage to the quality of life style of oldsters 60 years old and over. 122 numbers of oldsters who came to aid to the health center were put to survey. This was taken place within the areas of Deajun, Koonsan, Mooju and Jinahn, thus procured the following result. 1. The length of edentulous period of 1-6years of oldsters aged around 60s showed 26.0%. The oldsters with edentulous period of over 7years aged in the 70s showed 26.1 % and 56.0% on oldsters aged in the 80s. This shows that as the age increases the edentulous period lengthens. (P<0.05) The length of time of using the denture shows. llyears or over on women 41.9%, less than 6years on men 71.4% as the highest rate. 11 years or over on towns/subcounty show 57.5%, small and medium cities more than 1 year 63.6%, less than six years also 63.6% and Kwangyuk city 47.6%. 2. The complacency on medical treatment of dentures was highest in Kwangyuk city of 61.3%, compared to towns/subcounty of 50.8% and small and medium cities of 33.3%. (P<0.05) 3. The complacency on mastication and pronunciation appears, 2.74% in Kwangyuk city, 3.10% in towns/ subcounty which is higher than the small and medium cities showing 1.09% on average. Satisfaction rate tends to be higher as the length of time of using the denture is longer. 4. Inconvenience on eating habits caused by dentures were felt by women. Wanting to get a new denture was 25.6% by women showing much higher rate than that of men which is 2.8% by men. (P<0.05) 5. The complacency of change in their life style after wearing the dentures were higher in Kwangyuk city of 64.5% whereas it showed 27.0% in towns! subcounty and 16.7%in small and medium cities.

The changes of texture, composition of cell wall polysaccharides, polygalacturonase (PG) activity and soaking effect during preserving of persimmon at various tempoeratures were estimated for the purpose of investigating the softening characteristics of persimmon fruit. The softening of persimmon was most promoted at $25^{\circ}C$, where in the higher temperature, at $45^{\circ}C$ it was inhibited. During softening adhesiveness increased, cohesiveness and gumminess decreased. This phenomenon was obvious at $25^{\circ}C$. By soaking in water at $50^{\circ}C,\;70^{\circ}C$ for 30 minutes PG activity and softening was inhibited. Ionically associated pectin (IAP) and covalently bounded pectin (CBP) fractionated from crude cell wall of fresh persimmon were respectively degraded about 60% by PG curde enzyme of softened persimmon. And the degraded ratio of polysaccharides composed of pentose and hexose was very similar to that of polyuronide.

Purpose: This study investigated knowledge of and attitudes toward advance directives (ADs) among middle-aged women in South Korea, their willingness to write ADs in the future, and the factors related to knowledge of and attitudes toward ADs. Methods: Data were collected using a self-administrated questionnaire completed by 154 middle-aged women aged 50 to 64 from February to March 2020. The questionnaire asked about participants' knowledge of and attitude toward ADs, willingness to write ADs in the future, experiences with life-sustaining treatment within their families, experience making decisions about life-sustaining treatment, and demographic characteristics. Results: Scores for both knowledge of and attitude toward ADs were relatively high. About 60% of participants gave wrong answers when asked if attorneys were required for writing ADs. A higher knowledge score was significantly associated with a higher attitude score (r=0.227, P<0.01). The women were more likely to be willing to write ADs in the future when they reported a middle income level rather than a lower income level (odds ratio [OR]=5.952, P<0.01), considered themselves unhealthy (OR=5.873, P<0.01), and graduated college or higher (OR=4.096, P<0.05). Furthermore, women who thought that ADs would have an impact on treatment (OR=1.869, P<0.05) and on their families (OR=1.447, P<0.05) were more likely to be willing to write an AD. Conclusion: This study shows that wrong information about ADs persists among middle-aged women, and significant factors associated with knowledge of and attitude toward ADs were identified. Targeted education programs about ADs need to be developed for middle-aged women.

Purpose: This study aims to determine the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities, and the characteristics that comprise the types thereof. Methods: Q methodology, which analyzes the subjectivity of each type, was used. The 37 selected Q statements from 32 participants were classified into the shape of a normal distribution using a 9-point scale. The collected data were analyzed using the PC-QUANL program. Results: The survey revealed that the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities can be divided into three types: a rational dignity emphasis, an autonomous right to life belief, and conflict avoidance. All three attitudes regard human beings as possessing dignity, and life and death as elements to be experienced as aspects of human life. Bioethical values are critical to treatment and care; however, it is sometimes also held that humans have the right to commit suicide. Conclusion: This study enhanced our awareness of nursing students' bioethics. The findings can be used as a basis for the design of differentiated bioethics education according to each type of bioethical subjectivity. This calls for diverse research on bioethics and the implementation of effective bioethics education.
