Korean population is now aging at an unprecedented rate. Fertility decline together with rapid improvements in life expectancy is the dominant demographic trend. As human life and housing environment are inseparably related to each other, the importance of conditions of housing environment for active aging among seniors has been received considerable attention as vital ones to expand the independency period of seniors. The purpose of this case study is to identify relationships between environmental affordance and perceived holistic health of the active elderly living in a retirement community located in Seoul. With spending time personally in the community to observe their lives, the researcher could be in close rapport with the residents. After the period of getting familiar with each other, in-depth individual interview and focus group interview were conducted and then, qualitative analysis was completed. As a result, general evidences showed that perceived seniors' health on the whole was improved physically, socially, and mentally by moving into the community providing appropriate environment affordance with the older adults. The study presents that retirement relocation into an improper environment may be a negative challenge, however, it may positively influence on the health and well-being of those who live there if the environment properly supports seniors‘ needs physically and socially

Purpose: This research was conducted to examine the successful aging and identify factors influencing successful aging in the Korean elderly. Methods: The subjects were 4,507 elders and data were collected from the 4th Korean Longitudinal Study of Ageing in 2012. The data were analyzed using frequencies, weighted percentage, ${\chi}^2$ test, and logistic regression. Results: The results of this study showed that 19.6% of the participants were categorized to successful aging. The domains of the absence of disease and disability and maintaining physical and mental functioning showed a high rate of achievement, while the domain of active engagement with life showed a low rate of achievement compared to others. Successful aging was influenced by gender, age, subjective economic status, subjective health status, and family support, particularly spouse's support. Conclusion: Intervention programs to increase the prevalence of successful aging are required. Especially programs for strengthening spouse's support and enhancing subjective health status are required.

Marine algae contain a variety of substances, such as mycosporine-like amino acids, which can defend against UV irradiation. Among them, Porphyra-334 derived from Porphyra yezoensis is attracting attention as a novel active ingredient for anti-aging cosmetics because of its excellent anti-oxidative, anti-inflammatory, and wound-healing properties through promoting skin cell migration. In this study, a process using direct current (DC) for increasing the yield of large-scale purification of Porphyra-334 was developed. When DC was applied to obtain Porphyra-334 efficiently, the purification time was shortened by approximately 1/4 compared with the process wherein DC was not applied; moreover, the yield of purification was improved.

최근 디스플레이 기술 발전과 함께 AMOLED(Active Matrix OLED) 패널(Panel)의 생산과 수요가 급증하고 있다. AMOLED 패널은 기본적으로 LCD와는 다르게 백라이트(Backlight)를 필요로 하지 않아 적은 소비전력으로 선명도 있는 영상의 출력이 가능하다. 따라서 세계적으로 AMOLED 시장이 커지고 있다. 이에 따라 생산에 필요한 검사 장치의 수요도 확산되고 있다. AMOLED 패널 에이징(Aging) 시스템의 검사 장치는 MES(Manufacturing Execution System), MIS(Management Information System)와 연동하여 운영되며, 네트워크 환경을 구축하는 것이 효율적이다. 패널 에이징에 사용되는 검사 장치는 다중 신호를 출력하는 기능을 가진 신호 생성기(Pattern Generator)이다. 다수개의 신호 생성기를 운영하기 위해서는 효율적인 설계가 필요하다. 이를 해결하기 위해 본 논문에서는 신호 생성기를 원격으로 통합 제어하기 위한 방법과 AMOLED 패널을 구동시키기 위한 방법을 제안하고 이를 구현하였으며, 이에 따른 타이밍과 전원 설정 결과를 제시하였다.

Objectives : According to Rowe and Kahn (1998), successful aging is the combination of a low probability of disease, high functioning, and active engagement with life. The purpose of this study was to assess the relationship between active engagement with life and functioning among the community-dwelling elderly. Methods : Data were collected from Wave 2 of the Suwon Longitudinal Aging Study (SLAS), consisting of a sample of 645 persons aged 65 and older living in the community. A social activity checklist and social support inventory were used as measures of engagement with life, along with the Physical Functioning (PF) scale as a measure of functioning. The effects of social support and social activity on physical functioning, taking into account the covariates, were analyzed by hierarchical linear regression analysis. Results : Maintenance of social activity and social support were significantly associated with higher physical function, after adjusting for sociodemographic and health-related covariates. Social support appeared to be more prominent than social activity in predicting physical functioning. Conclusions : Social support and social activity are potentially modifiable factors associated with physical function in older persons. Studies examining the role social engagement may play in preventing disability are warranted.

본 연구는 주요 목적 달성을 위해 라인댄스와 리듬체조 중심의 신체활동에 참여하고 있는 65세 이상 노인 202명을 대상으로 성숙한 노화태도, 우울 그리고 성공적 노화 설문지를 이용하여 연구를 진행하였다. 연구결과를 제시하면, 첫째, 신체활동 참여 노인들의 성숙한 노화태도가 높을수록 우울은 감소하였다. 둘째, 신체활동 참여 노인들이 성숙한 노화태도를 높게 인식할수록 성공적 노화도 높았다. 셋째, 신체활동 참여 노인들이 우울을 높게 지각할수록 성공적 노화는 낮아지는 것으로 나타났다. 이상의 결과에 근거하면, 노인들이 신체활동에 규칙적으로 참여할 수 있도록 독려하고, 우울에 대한 적극적인 중재를 통해 신체활동 참여노인들이 성공적 노화를 이룰 수 있도록 해야 할 것이다.

The aging diagnosis method using partial discharge measurement detects discharge signals that critical cause of failure in insulation material operated a long time and can diagnose aging state of insulation materials with an aging analysis algorithm. The HFPD measurement method is a technique to analyze aging state of high voltage insulation materials and detect higher frequency signals than conventional PD measurement method therefore it takes less noise effect and could execute active line measurement. It is possible to analyze main discharge phenomena and obtain access to aging progress occurred in insulation materials through accumulation of HFPD signals during determined interval and expression of fractal dimension using statistical process of accumulated signals. The HFPD signals that occurred in each applied voltages are measured during 180 cycles and accumulated to the same phase of one cycle. These patterns that made by previous method are normalized with logarithm function and than inputted to neural networks. The aging diagnosis of insulation material was possible and the recognition ratio of neural network appeared very high.
