The concepy of positive aging describles the adverse effects of age on the lifetime of units. Various aspects of this concepts are described in terms of conditional probability distribution of residual life times, failure rates, equilibrium distributions, etc. In this paper we will consider some partial ordering relations of life distribution under residual life functions and equilibrium distributions.

본 연구는 고용보험 DB를 이용하여 구축한 사업체패널 자료(2000~2009년)를 이용하여 고연령층의 고용변화가 청년층 고용에 미치는 효과를 분석한다. 구체적으로 본 연구는 사업체 수준에서 (1) 고령근로자의 비중 증가가 청년층 고용에 미치는 영향과 (2) 고연령층 고용과 청년층 고용 간의 일자리 경합 여부를 실증분석한다. 사업체패널 전체를 이용하여 추정한 결과에서 고연령층의 고용 증가와 노동력 고령화가 청년층 고용 감소를 동반한다는 증거는 발견되지 않는다. 그러나 이와 같은 분석 결과가 하부 표본별 추정에서는 일관되게 관찰되지 않는다.

Living cells are continuously subject to all sorts of stress such as ultraviolet rays on skin cells. Tests made in various laboratories show that when young fibroblasts (Le. at the beginning of their proliferate life) were repeatedly put under stress at subletal doses, they acquired a phenotype similar to Senescence Induced Prematurely by Stress (SIPS). The work presented hereafter was made on a new model of senescence induced prematurely by stress from ultraviolet Brays (UVB). The human fibroblast model was put under repeated UVB stress, causing SIPS. Several ageing biomarkers were used in order to characterise the cells that underwent stress:. an increase in the proportion of positive cells with senescence associated $\beta$-galactosidase activity (SA $\beta$-gal) measured by a specific coloration,. the proportion in the different morphological stages that fibroblasts undergo during culture visualised by microscopic observation,. the expression of genes known for overexpressing during senescence, particularly fibronectin and apolipoprotein J, measured by Real Time-PCR,. the common deletion of 4,977 bp in mitochondrial DNA, evaluated by nested PCR. Studying the variation of these 4 biomarkers, we have evaluated the protective effect of a Laminaria digitata extract (LDE) that can be used as a natural active ingredient for anti-ageing cosmetics.

In this paper, testing exponentiality against new better than used in convex average and denote by (NBUCA), or its dual (NWUCA) is investigated through the U-test. The percentiles of these tests are tabulated for samples sizes n = 5(1)40. The power estimates of the test are simulated for some commonly used distributions in reliability. Pitman's asymptotic efficiency of the test is calculated and compared. Data of 40 patients suffering from blood cancer disease (Leukemia) is considered as a practical application of the proposed test in the medical sciences.

An increase in the proportion of Korean population in older age is much faster than the rest of the world. Along with rise of nuclear family due to rapid industrialization, informatization and materialization, ageing, on current situation in Korea that a reality of being diminished consciousness involving the sense of filial piety, and of respect or honor for the elders, does mean that such topics in ageing have become sociocultural issues that a nation should get more deeply involved in caring later life of the elderly population in an official and obligatory manner. Under this circumstance, an exhibition space in the hall intended for experiencing the later life of the elderly will surely play the role of locomotive in the respect of education to understand aging adults, and to promote development of health and welfare industry, especially for older population, also in creating and developing a positive and desirable culture and environment. To implement design project concerned with the space for the elderly population in a more careful and effective manner, the features of the Old Age Experience Hall that will satisfy the requirements thereof and the space compositions as well as characteristics of three exhibition halls having already been operated were analyzed examining closely the current facing issues in this aging society and also investigating the aging process related to physical functions of older adults. Based on those analyses, this study was aimed to prepare an efficient and systematic theoretical foundation for planning space composition of the Old Age Experience Hall further having extracted basic directions for design from, which should be meticulously considered and reflected so as to make the Old Age Experience Hall function properly.

본 연구의 목적은 주관적 건강상태 및 정신건강(우울), 그리고 건강정보이해력 및 정신건강정보이해력이 노인의 심리사회적 노화인식에 미치는 영향을 확인하고, 향후 이들의 노후에 주는 시사점을 찾는데 있다. 이를 위해서 한국연구재단의 인문사회역량강화 지원사업의 '연령주의 및 연령통합에 대한 조사' 자료를 활용하여 65세 이상 노인 400명을 추출하여 분석에 사용하였다. 연구결과 노인들의 심리사회적 노화인식은 부정적인 것으로 나타났으며, 정신건강변수인 우울이 높고, 건강정보이해력과 정신건강정보이해력이 다소 낮은 수준인 것으로 나타났다. 회귀분석결과 우울과 주관적 건강상태, 정신건강정보이해력이 심리사회적 노화인식에 영향을 미치는 요인으로 확인되었다. 그러나 건강정보이해력은 노인의 심리사회적 노화인식에 유의미한 영향을 미치지 못하는 것으로 나타났다. 이러한 연구의 결과를 바탕으로 노인의 긍정적인 심리사회적 노화인식을 증진시키기 위한 정책적 실천적 방안을 모색해 보았다.

Aging phenomenon is an important issue in Korea national policy. This aging phenomenon depends on the social and environmental characteristics of regions. Also aging phenomenon and regional characteristics have spatial dependency. The purpose of this study is to discover the spatial changes in aging population rate and to find local factors of regional aging phenomenon considering spatial autocorrelation. For spatial analysis of ageing phenomenon, local Moran's I and Geographically Weighted Regression (GWR) were applied. As the results, the most significant changes of aging phenomenon appeared between 2000 and 2005, and most of hot-spot regions (aged regions) were distributed in Jullanam-do and Jullabuk-do. The results of GWR (R-square: 0.681) shows that total fertility rate, the number of doctor per 1,000 people and forest area rate have positive relation with aging population rate, but the number of private academy per 1,000 people has negative relation.

The purpose of this study is to investigate productive activities effect on psychological well-being in the elderly. As people grow older, the level of physical function and psychological well-being is decreased. But We verified maintaining productive activities could make buffering effect on psychological well-being. And We investigate what kind of productive activities could effect on psychological well-being by gender. As a result, there were differences in self efficacy belief, life satisfaction and depression by age, education, absence of spouse, subjective economic status and physical function. Group activity and domestic labor had on affirmative effect on self efficacy belief in male and female elder. Learning activity had on positive effect on life satisfaction in female. Depression was negative influenced by voluntary activity and domestic labor in female and pay work, group activity and domestic labor in male.

The concept of positive ageing describes the adverse effects of age on the lifetime of units. Various aspects of this concept are described in terms of conditional probability distribution of residual life times, failure rates, equilibrium distributions, etc. In this paper, we will consider some partial ordering relations of life distributions under residual life functions and equilibrium distributions. Under residual life distributions, we study the relationships of IFR, NBU and NBUFR classes and that of DMRL and NBUE classes, By using WLR ordering comparison between F and its equilibrium $H_F$, we can decide if F belongs to NBUFR class.

Near Infrared spectroscopy (NIR) used on human skin measurement was explored in the past decade. Many publications in different journals and magazines discussed the feasibility of the NIR technique for cosmetic product property studies. Based upon the results of pioneers, we have pursued some work of the NIR instrument coupled with a probe module for skin measurement in vivo and vitro. In part I of this paper, the specific Near Infrared spectroscopy instrument stability, human subject conditions and other parameters, which could affect the measurements reproducibility are discussed. Second derivative NIR spectra and Principle Components Analysis (PCA) are utilised for data interpretation. In part II of this paper, the relationship of human skin moisture and ageing, the gender information and finally, the discovery of penetration depth of NIR incident light on skin are reported. A theoretical penetration depth calculation equation is proposed. In part III, the study results of a couple of commercial skin care products effect will be described. The skin lotions were applied on human skin (in vivo) in order to exam the NIR feasibility to monitor the changes of moisture level. The results are consistently positive. From our primary study, it can conclude that the NIR is potentially a very powerful instrument for skin condition diagnostics, either for cosmetic and/or for medication purposes.
