The trend change in aging properties, such as failure rate and mean residual life, of a life distribution is important to engineers and reliability analysts. In this paper we develop a test statistic for testing whether or not the failure rate changes its trend using censored data. The asymptotic normality of the test statistics is established. We discuss the efficiency values of loss due to censoring.

Land cover and land use change data are important in many studies including climate change and hydrological studies. Although the various theories and models have been developed, it is difficult to identify the driving factors of the land use change because land use change is related to policy options and natural and socio-economic conditions. This study is to attempt to simulate the land cover change using the CLUE model based on a statistical analysis of land-use change. CLUE model has dynamic modeling tools from the competition among land use change in between driving force and land use, so that this model depends on statistical relations between land use change and driving factors. In this study, Yongin, Icheon and Anseong were selected for the study areas, and binary logistic regression and factor analysis were performed verifying with ROC curve. Land cover probability map was also prepared to compare with the land cover data and higher probability areas are well matched with the present land cover demonstrating CLUE model applicability.

'생애과정 관점' 은 생애과정을 제도와 역사에 내재된 단계화된 연령구조로 인식하고, 맥락적 관점에서 개인과 집단의 생애를 이해하려는 이론적 방향이다. 독일과 미국을 중심으로 사회·역사적 변화의 맥락 속에서 생애과정을 분석하고, 생애과정에 미친 제도와 국가의 역할을 다루는 연구가 이루어졌고, 노동궤적에서 나타나는 경로와 노동성과의 차이, 생애과정에서 나타나는 불평등에 관한 연구 등에서 생애과정 관점이 적용되어 왔다. 국내에서도 다양한 분야에서 생애과정에 관한 연구가 시도되고, 결과가 축적되고 있으나 이론적 방향이나 체계로서 확립되지는 못하였다. 생애과정 관점을 적용하여 개인의 생애과정과 역사적, 사회적 변화를 접목시키는 시도로 1930~1979년 사이에 출생한 코호트의 역사적 위치를 확인하고 성인으로의 이행과정에서 나타난 변화를 추적하였다. 그 결과, 교육기간의 연장으로 인해 후속 이행의 시기와 구조에 변화가 발생하였고, 1960년대 출생코호트까지 젊은 코호트로 올수록 교육종료와 노동시장 진입, 결혼과 첫 출산이 이루어지는 시점이 지연됨과 동시에 대부분의 구성원이 압축된 연령 구간에서 이행을 완료하는 생애과정의 표준화가 이루어졌음이 확인되었다. 1970년대 출생 코호트는 이전 코호트와는 다른 이행패턴을 보이고 있으나 이행시기의 지연으로 구성원의 이행이 완료되지 않은 우측 절단이 발생하여 그 정확한 변화를 확인하지는 못하였다.

The purpose of this study is to find out the features of the Korean family change since 2,000 and to interpret the meaning of the change on the basis of the critical review of both the positive perspective and the negative perspective of the family change in Korea. Through the method of the literature review and the analysis of the various statistics by KOSTAT, it is drawn that explaining the change only by "diversity of family compositions" is not enough to figure out the meaning of the family change in Korea today and that it is needed to go further to approach the change as disintegration of the 'nuclear' composed of the married couple and their children. It is also drawn that the disintegration has led to weakening of the long term functions by the family, i. e., the function of life and of the virtues, which shakes the way of human life and the order of our society. Therefore, the present family change in Korea is to be understood as crisis, not as progress. And it is recommended that the family politics in Korea is to be focused on the ways for the healthy functioning and rebuilding the nuclear of the family.

The purpose of this study was to provide the fundamental data for the effective housing remodeling plan. Through the questionnaire survey, the actual conditions of remodeling in apartment housing were investigated. And as the result of statistic analysis, the relationships between characteristics of remodeling and building life-cycle, and family life-stage, were found out. The major findings of this study are as follows; 1) Most of apartment residents have remodeled the family living space and private living space. In detail, they performed remodeling frequently the change of finishing materials, facilities and equipments, and the change of the location of curtain wall ＆ storage fixtures. 2) It might be predicted that the building life-cycle was influential variable to predict apartment residents' remodeling. Therefore, in planning the support service for the remodeling, the building life-cycle should be taken into consideration.

From the field survey of the main ethnic minority areas in the south China, it is found that political, economic, cultural and natural environmental changes are the main reasons leading to the change of customary law. The power mechanism of the customary law change include the three aspects, such as the promotion of country elite, the dominance of grassroots government, and the daily demands of the villagers, which promote the change of customary law alone or together. Through the application of customary law, the country elites can adjust and refine the rules of customary law in order to make out the new customary law and promote its development. In the current pattern of rural governance, grassroots self-government is actually the "official supervision of people's autonomy". The executive power of the grassroots government often intervene the practice of customary law and other informal rules. This is another mechanism of customary law change. Customary law arises from the practice of the daily life of the villagers. If the villagers think that the norms of customary law cannot meet the actual needs of daily life practice, the customary law will be promoted in the form of collective consultation. This is the most important dynamic practice mechanism of customary law change. Transformation and abandonment are the two ways to change customary law. No matter what kind of change does not lead to the demise of the customary law system, the demise of the customary law is only an outdated result, which is made by the universality, nature and objectivity of customary law. The procedure of customary law change is the process of continuation and rebirth about customary law. The result of the change is to produce the new customary law of keeping pace with the times, and the customary law will be presented with new content and form after the change. The continuation of customary law means the inheritance of traditional customary law, but it is based on the transformation of traditional customary law. The rebirth of customary law means that the traditional customary law is completely discarded. But it will produce new customary law rules and be based on the needs of social life practice. Customary law occupies a pivotal position in the normative system and the national law cannot be replaced. The purpose of customary law change will let the customary rules better adapt to the development of modern society, adjust the social relations more reasonably and better meet people's needs of production and life, which is decided by the character of customary law.
