Chronic diseases such as hypertension require a differentiated approach according to age and life cycle. Chronic diseases such as hypertension require differentiated management according to the life cycle. It is also known that the cause of hypertension is a combination of various factors. This study uses machine learning prediction techniques to analyze various factors affecting hypertension by life cycle. To this end, a total of 35 variables were used through preprocessing and variable selection processes for the National Health and Nutrition Survey data of the Korea Centers for Disease Control and Prevention. As a result of the study, among the tree-based machine learning models, XGBoost was found to have high predictive performance in both middle and old age. Looking at the risk factors for hypertension by life cycle, individual characteristic factors, genetic factors, and nutritional intake factors were found to be risk factors for hypertension in the middle age, and nutritional intake factors, dietary factors, and lifestyle factors were derived as risk factors for hypertension. The results of this study are expected to be used as basic data useful for hypertension management by life cycle.

This study illuminates the mechanism of life course on labor status of old age complementing the limits of labor status hypothesis of old age and model of statues attainment and combining them. The main results from this analysis are summarized in four points. Firstly, older men mostly engaged in agriculture, forestry and fishing industry or low-class occupations. A very small portion held high level or professional occupations. Regular full-time employees or employers were only 4.4% while, about 70% of older employees were temporal employees or self-employed. This shows that the elderly affluence hypothesis which alleges that most older men maintain high level occupations, applies to only a few. The second finding is that wealth differentials are sizable: about 20% of older workers own less than 50 million won, while 9.3% possess more than 600 million won. Therefore, it is not safe to claim that most people have accumulated enough wealth for old age according to the elderly affluence hypothesis. This gap being mainly reflected by education level, suggests that the model of status attainment is appropriate as wealth accumulation hypothesis. Thirdly, educational level determined not only lifetime careers, but also labor status of old age. Fourthly, using path analysis, the last finding is that education had effect on labor status of old age through lifetime career and wealth. That is, old men who have low education level had unstable lifetime career and own less wealth. They work in low income job, low social occupations and unstable occupation type in old age. This shows that life inequality continues until old age. Therefore, the inequality of education opportunity, spread of part-time work and small scale self employees should be discouraged. Furthermore, related policy should be provided in order to prevent being caught in unstable work.

The purpose of this study is to explore the life history of a highly experienced elementary school teacher, Mr. Park and to understand how his science teaching practices have changed throughout his educational career. Using life history interviews with Mr. Park and his life history materials as data sources, a life story of the participant teacher was constructed. The ways teaching changed in the inter-relationship between external and personal factors were then analyzed according to three temporal periods of teaching changes. It was revealed that in the first period of teaching change, Mr. Park changed his science teaching practices by actively accepting influences from external factors, which in turn enabled him to start developing his expertise in student-centered science instruction. By contrast, in the second period of teaching change, Mr. Park strengthened his own ways of teaching while responding critically to the trends of educational change by external factors. In the third and final period of teaching change, Mr. Park made changes in teaching practices by taking advantage of his personal factors to convert influences of external factors into positive ones. Based on these findings, it was suggested that educational policies for teaching changes should be provided in consideration of teachers' life cycles and their expertise and that teachers should make efforts to reflect on the factors for educational change and transform them into positive ones.

This study, based on the research on the history of life, aimed to recompose and analyze into what life progressive structure the life experience by the mentally ill, after the onslaught of the disease, developed in a bid to understand the risk progress in the mentally ill's life, and to determine what contributed to the current stabilized recovery and adjustment. Five mentally ill persons participated in the study, and Sch$\ddot{u}$tze's narrative interview was used to gather data. The gathered data were analyzed according to Sch$\ddot{u}$tze's process structure of life. The interviewees' life experiences were chronologically organized as understood, and significant stories were recomposed that not only brought about changes but also helped overcome their disabilities in the process of treatment and rehabilitation after the onslaught of the disease. As a result, their experiences were recomposed into the stage of onslaught of the mental illness and confusion, and into the stage of intensive treatment and rehabilitation. The former was categorized into suppression by the disease, repetition and endurance of the painful life, and separation from their family and frustration. The latter was categorized into the rediscovery of self through social role change, others who helped realize the life potential, the expansion of mental health services in the community, obstacle to the integration of communities, re-integration of family relationships, re-analysis of experience of the disease through the examination of the life prior to onslaught of the disease, and expectation for the future. Also, these themes were comparatively examined so as to examine the crisis progress in the mentally ill's life after the onslaught of the disease, as well as the life transfer process through positive rehabilitation. Lastly, on the basis of these results, important areas of mental health services for the mentally ill were discussed.

Cost, schedule, quality are the essential parts of success of every construction project. It is especially true in high-rise building construction. Among the construction components in high-rise building construction, curtain walls are very important elements for the project success because they take large portion of cost and schedule. However, curtain wall construction process are very complicated, where many entities including designers, suppliers, contractors and even maintenance contractors are involved. Therefore, control and management of their relationships and production process are critical. It is suggested that this can be solved by the concept of Supply Chain Management which is supported by the automated information technology with Radio Frequency Identification. Such concept is defined as 'Automated Life-Cycle Management System Based On SCM' and this study suggests rode map to establish the system.

This study has two objectives. First, this study examines subjective well-being among elders that operationalize life satisfaction and aging anxiety, guided by life-course perspective. Second, it examines the relationship between subjective well-being and age-friendly environment factor structure among age-cohort groups. This study employs the stratified sampling method from 4,000 Seoul citizens. Main findings from the multivariate regression analyses include: (1) as age increases, aging anxiety levels appeared to be higher, while decreasing the life satisfaction. (2) a substantially larger variance of life satisfaction and aging anxiety was accounted for by demographic variables and age-friendly environments across age-cohort groups. (3) the influence of age-friendly environment factors such as neighborhood problems, accessibility to social activities, social services and parks on subjective well-being was different across age-cohort groups. This study discusses the policy and practical implications of the results.

This study looked into the process by which Haseo(河西) Kim In-hoo(金麟厚:1510~1560), a neo-confucian scholar of mid Joseon Dynasty, was recognized and adored as an inheritor of traditional academic genealogy of neo-confucianism of Joseon Dynasty. I intended to examine the process of personal embodiment affected or excluded in certain manners by various materials covering the lifetime of bygone persons based on the process of such embodiment. The part related to childhood of Haseo was arranged newly to highlight solid relationship between Kim In-hoo and King Injong(仁宗). That was because Kim In-hoo raised the issue of loyalty and fidelity, one of the most important and most contentious issues at that time, in connection with reinstatement of GimyoSarim(己卯士林, progressive political faction with young officials), and King Injong was the king who reinstated Gimyo Sarim. That played a decisive role in establishing the image of Haseo, a classical scholar with unwavering integrity and loyalty. During the Late Joseon Dynasty, canonization of Haseo was made under the leadership of King Jeongjo(正祖) and Seoin(西人) in royal court. In the 17th century, Seoin scholars revised the materials related to lifetime of Kim In-hoo in various way and proofread and published the collection of literary works by Kim In-hoo. That aimed to establish scholastic system associated with Seoin and legitimacy of study as pursued by Seoin. This made progress with adoration towards scholars affiliated with Seoin, including Yulgok(栗谷) Lee Yi(李珥). Finally, King Jeongjo showed strong intention to take the lead as sovereign in the process while Haseo was canonized into national academy in the 18th century. That came from the desire to solidify his status as a teacher who took pride in taking responsibility for the dynasty's authentic study, as well as the king heading the dynasty politically.
