In this study, the insulation selected in degra-dated-power cable has been observed and aging process about the insulation has been investigated. Most Insulation aging process initiates in the interface of semiconducting layer and the type of the process is the fractal form that was observed between the the semiconducting layer and insulation layer. It is possible to estimate degree of the degration of cable with breakdown test and obtained data have been used to get parameters in order to use Weibull distribution. With this method it is considered to be possible to estimate situation of degration and life prediction.

In modem society, the development of science and industrialization has brought economic growth, and better living environment, improved food life, advanced medicine, and increased span of life have leaded us into the aging society. In the current situation to move toward the aging society, it's needed to prepare housing planning for retirement community in consideration of the physical and psychological and behavioral features of the elderly to raise their quality of life. The purpose of this study was to map out proper housing planning for retirement community in consideration of the physical, psychological and behavioral characteristics of senior citizens, instead of just focusing on comfortable and convenient one.

Kitchen space is one of the most dangerous places for the elderly. Modification of kitchen space for improving safety and independence for older residents is very important factor for aging -in-place. The purpose of this study wes to identify the current situation and modification of kitchen space by elderly-headed household. The sample included 108 respondents over the age 65 who consisted of elderly-couple or single person household with homeownership in Seoul. The data were analyzed by descriptive statistics. Based on the findings of the study, the present incidence and recognition of future need in kitchen modification were identified. Changes in kitchen space made tended to be nonstructural or relatively inexpensive items. In conclusion, this study suggests several ideas for improving current physical problems of kitchen space to support daily living of older residents.

Statement of problem. Soft lining materials, also referred to as tissue conditioning materials, tissue heating materials, relining materials, soft liners or tissue conditioners, were first introduced to dentistry by a plastic manufacturer in 1959. Since the introduction of the materials to the dental field, their material properties have been continually improved through the effort of many researchers. Soft lining materials have become widely accepted, particularly by prosthodontists, because of their numerous clinical advantages and ease of manipulation. Unfortunately, few reports have been issued upon the topic of increasing the bond strength between the base metal alloy used in cast denture bases and PMMA soft liner modified with 4-META, nor upon the pattern of debonding and material change in wet environment like a intra oral situation. Purpose. The purposes of this study were comparing the bond strength between base metal alloy used for the cast denture bases and PMMA soft liner modified with 4-META, and describing the pattern of debonding and material property change in wet environment like the intraoral situation. Material and Methods. This study consisted of four experiments: 1. The in vitro measurement of shear bond strength of the adhesive soft liner. 2. The in vitro measurement of shear bond strength of the adhesive soft liner after 2 weeks of aging. 3. A comparison of debonding patterns. 4. An evaluation the Relation time of modified soft liner. The soft liner used in this study was commercially available as Coe-soft (GC America.IL.,USA), which is provided in forms of powder and liquid. This is a PMMA soft liner commonly used in dental clinics. The metal primer used in this study was 4-META containing primer packed in Meta fast denture base resin (Sun Medical Co., Osaka, Japan). The specimens were formed in a single lap joint desist which is useful for evaluating the apparent shear bond strength of adhesively bonded metal plate by tensile loading. Using the $20{\times}20mm$ transparent grid, percent area of adhesive soft liner remaining on the shear area was calculated to classify the debonding patterns. To evaluate the change of the initial flow of the modified adhesive soft liner, the gelation time was measured with an oscillating rheometer (Haake RS150W/ TC50, Haake Co., Germany). It was a stress control and parallel plate type with the diameter of 35mm. Conclusion. Within the conditions and limitations of this study, the following conclusions were drawn as follows. 1. There was significant increase of bond strength in the 5% 4-META, 10% 4-META containing groups and in the primer coated groups versus the control group(P<0.05). 2. After 2 weeks of aging, no significant increase in bond strength was found except for the group containing 10% 4-META (P<0.05). 3. The gelation times of the modified soft liner were 9.3 minutes for the 5% 4-META containing liner and 11.5 minutes for the 10% 4-META liner. 4. The debonding patterns of the 4-META containing group after 2 weeks of aging were similar to those of immediaely after preparation, but the debonding pattern of the primer group showed more adhesive failure after 2 weeks of aging.

본 연구에서는 EPDM 고분자애자의 염무량 변화(salt:l0g, 25g, 50g, deionized water: 1000g)에 따른 표면방전과 환경적인 변화(salt fog 및 clean fog 그리고 raim)에 대한 누설전류 파형의 결과를 알아보았다. 기본파 및 3고조파 그리고 5고조파의 변화양상을 과전초기로부터 섬락시에 이르기까지 나타내었다. 표면열화의 진단기법을 개발하기위해서 누설전류파형의 주파수 스펙트럼을 이용하였고, 고분자애자의 표면열화에대한 환경적인 영향(clean fog, salt fog, rain)을 연구 하였다. 염분량의 변화시 기본파에 대한 저주파 고조파인 3고조파 및 5고조파에 대한 백분율(왜곡도)의 변화를 이용하여 표면 열화상태 및 정도를 정량화(a standard capacity)하여 나타내었다. 기본파에 대한 고조파 백분율인 왜곡율은 고분자 애자의 표면조건을 평가하는데 필요한 지시자라는 사실을 알 수 있었다.

Elderly population has increased rapidly and adjusting the environment is in demand to support their health. To improve the living environment of elderly, an appropriate plan for customized home modification is needed upon the personal contexts. The purpose of this study is to explain the sequence and to build an insight on customized home modification for vulnerable single elderly. It is a case study based on single target that includes 6 months of execution period deeply seeking the appropriate plan for implementation. The target is a male elderly aged 74 living in a single story detached house. The various research methods are applied in this study including exploratory, participatory, action and trade-off preference researches. The result shows that plan for home modification is complex outcome of interlocking uniqueness between residence environment and resident situation. If customized modification is targeted for residentially vulnerable social group, more sensitive approach aiming for the highest result is required due to financial constraint. To conclude, comprehensive understanding of overall circumstances of a dwelling, a resident and various stakeholder is essential throughout the process. Since the aging-in-place of elderly cannot be achieved without self-sustaining living environment, customized home modification should be a tool to meet housing suitability. It is important to strengthen the experts and future workforce with networks of local residents to share opinions and appropriate plans.

대한민국은 사회적 고령화 문제와 더불어 재난현장 대응활동의 주역인 소방공무원 조직의 연령 구성비의 고연령화 문제 또한 심각한 상황에 이를 것으로 전망된다. 대표적인 재난대응조직인 서울소방의 경우 향후 10년~15년 사이에 50대 이상의 비율이 31%에서 40%에 이를 것으로 예상되는데, 이는 재난 현장에서 강인한 체력과 건강한 신체를 필수 요소로 하는 소방공무원에 있어서는 일반직 공무원과는 달리 심각한 문제가 되지 않을 수 없다. 본 연구는 서울 소방공무원의 연령현황과 추이를 분석하고 국내 최초로 현장활동 소방공무원의 현장활동 한계의 기준 연령을 정의하고 3가지 분석기준을 통해 개괄적이나마 현장활동 한계기준을 도출하고, 이 기준을 통해 추이분석을 하였다.

우리나라도 대부분의 국가와 마찬가지로 직접적인 소득보장정책의 일환으로 사회보험방식에 의한 국민연금제도를 시행하고 있다. 그럼에도 불구하고 제도의 미비 또는 공적연금의 본질적 한계로 인하여, 고령자에게 실질적인 "인간의 존엄성을 유지하기 위한 최저생활의 보장"에는 미흡한 실정이고, 노인의 빈곤율은 OECD 국가들 중 1위이고, 공적연금의 사각지대도 매우 크다. 향후 저출산과 고령화가 더욱 진전될 경우 고령 저소득층의 문제는 심각한 사회문제로 폭발할 우려가 있다. 이 연구에서는 우리나라 노인의 노후소득보장에 관한 실태와 현황 분석과 현행 노인소득보장 법체계를 검토하고, 그 문제점을 도출해 개선방안을 마련하고자 한다.
