  • This study aims to consider the criteria and signification of 'aging' constructed in media in Korean society that has entered aging society. For the purpose, this study analyzed KBS the representative TV health programs. According to the result, designs the measurable indexes of aging to rank the casts. And it emphasizes to the casts that cannot reach a certain level the support from medical experts or advanced medical technology. With such characteristics of individual text, this paper found the ideological codes of the health programs. They contrast the elderly who have achieved successful aging from those that have not. They define the aged who have not practiced self-management or medical control to prevent aging properly as failure and also make fun of them. They draw aging that was not regarded as some kind of disease in the past into the area of medicine. Besides, the medicalization of aging regarded as an object for treatment may come to strengthen the control of medical experts and also individualize social issues.

  • Role of plant hormones on the leaf senescence of Phaseolus vulgaris were investigated by measuring the disassembly of chlorophyll-protein complexes in detached leaves treated with NAA, GA$_{3}$ , or BA. The loss of chlorophyll that was characteristic of leaf senescence induced disassembly of chlorophyll-protein complexed. During dark-induced senescence, PSI complex was rapidly degraded after the early stage, whereas RC-Core3 was slightly increased until the middle stage and slowly decreased thereafter. And gradual degradation of trimeric LCHII progressed after the late stage of senescence. Exogenous application of NAA and GA$_{3}$ had little or no effect in protecting disassembly of chlorophyll-protein complexes during leaf senescence compared to control. However exogenous BA application strongly leaves. In the simultaneous treatment of plant hormones and light, BA application under illumination of light was most effective in the stability of chlorophyll-protein complexes, particularly PSI, LHCII, RC-Core2, RC-Core3 and SC-1. these results suggest, therefore, that simultaneous application of BA and light induced synergistic effect on the stability off chlorophyll-protein complexes during leaf senescence.

  • 노화는 질병이 아니라 모든 생물이 본래 갖고 있는 하나의 과정이라고 산다. 노화연구는 우리를 자멸의 길로 끌어가는 「내부시게」론과 유전적인 실수와 공격으로 마침내 몸을 수리할 수 없을 정도가지 파괴한다는 주장 등 두개의 그룹으로 나눈다. 노화는 유전자 ,호르몬 ,분자 ,면역 조직반응 ,환경의 공격 그리고 일상적인 잘못을 포함하여 수십가지의 얼키고 설킨 과정이다. 이러한 노화를 막고 사람의 수명을 연장할 수는 없는가 실제로 인류는 지난 한세기동안 깨끗한 물과 백신과 같은 개량된 공중보건 덕택에 평균수명이 47세에서 79세로 2배나 늘어났다.

  • Dementia is defined as a syndrome which is characterized by various impairments in cognitive functions, especially memory function. Most of the diagnostic criteria for dementia include memory impairment as on essential feature. Memory decline can be present as a consequence of the aging process. But it does not cause significant distress or impairment in social and occupational functionings while dementiadoes. Depression may also be associated with memory impairment. However, unlike dementia, depression dose not cause decrease in delayed verbal learning and recognition memory. In dementia, different features of memory impairment may be present depending on the involved area. Memory impairment in cortical dementia is affected by the disturbance of encoding of information and memory consolidation, while memory imparnene in subcortical denentiy is affected by the disturbance of retrieval in subcortical dementia.

  • 노년이 되면 후두암이나 신경장애와 같은 질환의 빈도가 증가하는 것이 사실이지만 가장 흔한 음성변화의 원인은 후두의 노화현상에 따른 것이다. 연령과 무관하게 발생하는 성대결절과 같은 질환도 노화의 영향에 따라 그 심각성이 달라지게 된다. 따라서 노인의 음성문제를 다루려면 노화과정에 대한 올바른 이해가 필수적이다. (중략)

  • XLPE 절연 전력케이블의 제조과정에서 발생하는 가교부산물을 제거할 목적으로 14주기노화를 실시한다. 이 과정에서 가교부산물이 제거되는 효과도 있지만 열에 의한 구조적 결함도 생기게 되며, 이들 모두가 뇌충격파괴전압에 영향을 준다. 22.9kV 트리억제형(TR CNCV-W) 케이블에 대하여 14주기노화 전과 후의 파괴전압을 분석하였으며, 전반적으로 노화과정이 파괴전압을 감소시키는 결과를 보였으나 60 $mm^2$ 케이블은 상승효과와 감소효과가 비슷하게 작용하는 것으로 나타났다.

  • 모든 생명체는 나이를 먹으면서 노화해간다. 이러한 노화를 방지해 보려는 인간의 꿈은 노화의 본질이 무엇인지와 노화는 왜 일어나는지에 대한 의문 등을 끊임없이 제기하고 있다. 이런 노력들은 단순히 수명을 연장하기 위해서라기 보다는 살아있는 동안만이라도 젊음을 유지하고자 하는 욕망에서 비롯한 것일 것이다. 노화의 과장은 우리몸의 눈, 뇌, 심장등 구성기관 모두에서 나이를 먹으면서 일어나고 있다. 피부도 마찬가지여서 나이에 따라 어쩔 수 없이 노화해 간다. 즉 각질형성세포, 멜라닌세포, 땀샘들의 기능이 점차 떨어져 간다. 어린이들의 터질듯한 팽창력과 유연성을 가진 피부가 어느덧 청소년기의 매끄럽고 윤기가 흐르던 시절을 지나 성년기에 이르면 거칠고 메마른 상태가 되며, 그 후 주름이 지고 탄력성이 소실되는 노화 피부상태에 도달하게 된다. 피부, 눈, 신경 등 생체 노화과정의 생리적 규명이 현재 의학의 한 첨단분야로 등장하고 있으며, 피부노화에 대해서도 많은 연구가 진행중이다.

  • 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.
