This study explored the effects of Tai Chi on cardiovascular disease(CVD) risk factors among the Korean elderly. 68 elderly were selected and divided into two groups: an experiment group(34 patients) and a control group(34 patients). The experimental group practiced Tai Chi for 60 minutes a day, five times per week for 6 weeks total. The control group continued their routine levels of activity. CVD risk factors evaluated in both groups including body mass index, fasting blood sugar, triglyceride, high density lipoprotein cholesterol(HDL-C), and low density lipoprotein cholesterol(LDL-C). Each factor was measured before and after the 6-week intervention. Results showed that the experimental group had a significant decrease in measurements of body mass index, fasting blood sugar, triglyceride, and LDL-C levels. The experimental group also had an increase HDL-C level. Based on such findings, we believe that Tai Chi exercise program would function as an effective intervention strategy for preventing CVD in the elderly. Therefore, it is recommended that health and medical service personnel should seek to apply Tai Chi intervention as a daily component of elderly care.

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (${\chi}^2$= 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (${\chi}^2$= 8.892, p = 0.030), fish (${\chi}^2$= 32.241, p = 0.000), beans (${\chi}^2$= 14.770, p = 0.005), vegetables (${\chi}^2$= 12.706, p = 0.013), fruits (${\chi}^2$= 14.438, p = 0.006) and milk & dairy products (${\chi}^2$= 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

This thesis is studing Kim Chi-in's Life and Confucianism-Buddhism-Taoism-Unity of Namhak lind on Jinan in Junbuk. He combined thought of Confucianism-Buddhism-Taoism and drawed up religious doctrine, after spotting internal and external troubles of nation. Kim Chi-in was influenced by Lee Un-gyu's thought of Confucianism-Buddhism-Taoism-Unity. He spoke with emphasis of Tao in doctrine through religious experience. The root of Tao originates in heaven. Although Tao was divided according to Confucianism, Buddhism and Taoism for the human's aspect of thought, it is ultimately the one. In time on explaining the one, he invoked 'eum(陰)', 'yang(陽)', 'che(體)'와 'yong(用)' as concepts of Neo-Confucianism. This ididn't incline to one side of Confucianism, Buddhism and Taoism. While he spoke with emphasis on Confucianism's ethics of 'yang' and 'yong' with Buddhism and Taoism's divine of 'eum' and 'che' as the center, he want to find pivot of thought. He especially seeked Younggamu(詠歌舞) of sing and dancing on training mind and body. This was that he let the people and scholars in retirement demand realization of Tao and aim at real virtue. The study of Kim Chi-in's thought and religion of Confucianism-Buddhism-Taoism-Unity will be an opportunity look around his identity for the traditional native thought and universality.

Exercise has been shown to positively influence quality of life for elderly men with a wide variety of medical illnesses. Tai chi exercise, a slow and graceful form of exercise and meditation, has especially been offered as the ideal exercise for elderly men with diverse conditions, such as people suffering from chronic heart failure or breast cancer survivors. In one recent study, Tai Chi was found to improve exercise capacity, sleep stability, and quality of life in heart failure patients including elderly men. The purpose of the study was to examine the effects of 16 weeks of Tai Chi exercise (3 times/week, 60 min/trial, 40-50% HRR) on physical and physiological changes. Sixty four healthy volunteers without any particular disease between the ages of 65 and 79 years participated in the study. The results were as follows; Significant changes of cardiac endurance, strength, muscle endurance, flexibility and balance were observed following 16 weeks of Tai Chi exercise (p<0.05). In addition, significant changes of diastolic blood pressure, body fat and fat-free mass were observed following 16 weeks of Tai Chi exercise (p<0.05). These findings suggest that a brief period of Tai Chi exercise is beneficial, particularly to elderly men. It is especially beneficial for body composition, and physical fitness factors such as cardiopulmonary endurance, muscle endurance, flexibility, and balance. Further study is needed in this area for specific disease patients.

In this study the disassembly process of chlorophyII (ChI)protein complexes of a stay-green mutant (ore10 of Arabidopsis thaliana) was investigated during the dark incubation of detached leaves. During this dark-induced senescence (DIS), the Chi loss was delayed in the mutant, while the photochemical efficiency of photosystem II (PSII) or Fv/Fm was accelerated when compared with the wild type (WT) leaves. This indicates that the decrease in Fv/Fm is a separate process and not causally-linked to the degradation of Chi during DIS of Arabidopsis leaves. In the native green gel electrophoresis of the Chi-protein complexes, which was combined with an additional twodimensional SDS-PAGE analysis, the delayed senescence of this mutant was characterized by the appearance of an aggregate at 1 d or 2 d, as well as very stable light harvesting complex II (LHCII) trimers until 5 d after the start of DIS. The polypeptide composition of the aggregates varied during the whole DIS at 5 d. Dl protein appeared to be missing in the aggregates. This result supports the idea of a faster depletion of functional PSH in the mutants compared with WT, as suggested by the earlier reduction of Fv/Fm and the stable Chl a/b ratio in the mutants. At 5 d, the WT leaves also often showed aggregates, but the polypeptide composition was different from those of ore10. The results presented suggest that the formation of aggregates, or stable LHCII trimers in the stay-green mutants, is a way to structurally protect Chi-protein complexes from serious proteolytic degradation. Detailed disassembly processes of Chi-protein complexes in WT and ore10 mutants are discussed.

Our study measures the Digital Life Index (DLI) of baby boomers by considering the utilization of digital devices in their everyday life. The study was conducted by implementing the following three-step approach: (1) development of survey questions and data collection; (2) build Digital Life Index (DLI) model and lastly; (3) empirical analysis using the Digital Life Index (DLI). In the first stage in order to develop the survey questions to measure the digital index, two surveys were conducted. For the first preliminary survey, it was done based on the existing literatures which enabled this investigation through FGI analysis involving real professionals. The second survey was conducted by commissioning a specialized external firm. In this survey, a total of 400 data was collected to verify the validity and objectivity of the data sample. The data gathered through the survey questions was used to develop the digital index. Firstly, the appropriate factors were extracted by conducting factor analysis. This factor analysis validates and verifies the factors which are appropriate in measuring Digital Life Index (DLI). The derived factors are broadly divided into five main factors. The first factor describes the possession, purchase and use of digital device (x1). Meanwhile, the second factor describes the digital device's software (x2) and the third factor describes the participation in utilizing digital device (x3). The fourth factor describes the utilization of digital device in human personal relationship (x4) and lastly, the fifth factor describes the effect of digital device in everyday life and work environment (x5). Secondly, the digital index model was developed. The variables to represent the Digital Life Index (DLI) are ${\chi}1t,{\chi}2t,{\chi}3t,{\chi}4t$ and ${\chi}5t$. Furthermore, as experience in using the digital index grows overtime, the growth can be represented by the "S" shape. Based on the results, Digital Life Index(DLI) is distributed with the highest point at 90.3 and the lowest point at 25.9.
