The processes and rates of groundwater recharge were studied by long-term monitoring of groundwater level and isotopic compositions of precipitation, surface water and groundwater in the Yeosu area. The isotopic compositions of surface water and groundwater were directly related to the precipitation event. It is also shown that the minimum amount of precipitation for infiltration to groundwater is about 20mm. The isotopic variations of groundwater shows that the Isotopic composition of groundwater changed by each precipitation event between June and Sep. 2000 is gradually changed without input of precipitation again. It indicates that the groundwater recharged from the upper part is mixed with the groundwater in reservoir. The infiltration rate of first precipitation event after a dry season is estimated to be 16.5% using isotopic mixing equations. It is expected that the groundwater recharge rate could be estimated more quantitavely, if the isotopic method is combined with the conservative methods.

1. 문제점(Setting of Problems) 산업의 급진적인 진보는 고도의 기술사회(high-tech societies)를 창출해 내었고, 이로 인해 생산양식뿐만 아니라, 가치체계 및 생활양식이 급진적으로 변화하였다. 동시에, 산업화 및 생활수준의 향상은 인구통계학적 변천(demographic transition)을 가져와, 인구의 노령화가 이루어졌다. 산업화에 의해 발생된 이러한 현상들, 즉 가치체계의 변화와 인구의 노령화가 바로 문제의 핵심인 것이다. 산업화는 효율(efficiency)에 높은 가치를 부여함으로써, 정신적인 인간관계측면의 중요성을 무시하고, 노령화란 다차원적(multi-dimensional) 문제를 일으켰다. 이러한 문제들의 해결책으로서 서구적인 가치개념은 노인들의 생활의 질(quality of life)를 향상시키지 못한 것으로 생각된다. 따라서, 물질적인 면 이외에 정신적인 면의 접근법을 필요로 하게 되는 것이다. 2. 연구의 목적(Objective of the Study) 이 연구의 목적은 한국에 있어서의 인구의 노령화의 원인과 결과에 대한 연구를 하는데 있다. 이러한 연구에 의해 노령화라는 다차원적 문제에 대한 지식을 얻으므로써, 사회, 공동체 및 가족 수준에서의 노령화 문제를 다루는데 있어 비서구적 접근법 및 정책적 전략에 관한 방안을 제시하게 되기를 희망한다. 3. 방법론(Methodology) 1) 자료 수집(Data Collection) 자료는 다음 세가지 원천으로 부터 얻어졌다. 첫째, 출판된 자료 및 회의서류 둘째, 한국보건사회연구원과의 협조로 행해진 설문지 조사 셋째, 자체 연구팀에 의해 행해진 면담 2) 자료분석(Data Analysis) 인과분석(cause-effect types of analysis)은 probit, logit, path analyses에 의해 행해졌다. 이 연구논문에는 trend analysis의 결과는 제시되지 않았는데, 이는 다양한 정부기관에 의해 출간된 분석들과 유사하기 때문이다. 4. 연구분석의 결과 첫째, 경제적 요인은 노인들의 생활상태를 결정하는데 가장 중요한 요인이라는 것을 알 수 있다. 둘째, 노인의 사회적인 통합이 강할수록 보다 행복한 생활을 영위하는 것으로 나타났다. 셋째, 성(sex), 교육정도, 주거지역 등이 노인의 고용상태 및 소득수준과 큰 관계가 있다. 넷째, 교육정도, 사회적 결합(social integration) 등이 건강상태와 밀접한 관계가 있다. 다섯째, 사회적 통합, 건강상태, 독립심 등이 노인의 정서적 상태에 큰 영향을 미친다.

고도의 산업화성장에 따라 도시의 기능이 지역간의 완전분리가 아닌 경제적 사회적 상호 연관성이 점점 증가하고 그 내용도 복잡하고 다양해짐에 따라 이에 대한 체계적인 분석이 필요하게 되었으며, 그에 대한 연구 또한 활발히 진행되고 있다. 그러나 기존에 연구에서 제시하고 있는 각 지역단위별로 취업자수에 대한 고용자수 비율 또는 출근통행의 유출량에 대한 유입량 비율 등의 단순지표를 이용한 지역간의 경제적 의존성을 설명하는 데는 한계가 있다고 할 수 있다. 따라서 본 연구는 지역간의 경제적 연관관계 즉 경제적 의존성을 복합적이고 표준화 할 수 있는 계량치로 추정하기 위해 두 변수 집합간의 연관성을 추정하는데 매우 유용한 분석기법인 정준상관분석 기법을 이용하여 추정하고자 하였다. 이에 수도권 72개존의 출근통행자료을 이용하여 지역간의 경제적 의존성을 측정하였으며, 각 존들로 구성된 지역간의 정준상관계수 및 각 존들의 정준가 중계수를 통해 통계적으로 정산되어진 표준화된 계수를 산출하였다. 그 결과 대존의 경우 경기도와 인천시는 각각 0.9753. 0.2968 정도의 서울에 대한 경제적 의존정도를 보이는 것으로 나타나 서울에 대한 경기도의 경제적 의존성이 높은 것으로 나타났으며, 산출된 정준가중계수를 살펴보면 분당구와 서울시의 중구는 서울에 대한 경기도의 경제적 의존성에 가장 높은 영향을 미친 것으로 나타났으며, 또한 중존에 해당되는 인천의 3개 권역, 경기의 16개 권역의 서울 5개 권역에 대한 경제적 의존성도 분석되었다.

In 2Y-TZP powders calcined at temperature range of 80$0^{\circ}C$0 to 150$0^{\circ}C$, the effect of stabilization and the transformability of tetragonal phase on the tetragonal to monoclinic transformation have been investigated. The transformability of tetragonal phase in calcined powders shows maximum at the calcination temperature of 130$0^{\circ}C$. This result is explained by a combined effect of the increase of particle size and of constrained force among the particles with increasing the calcination temperature. The amount of transformed monoclinic phase with calcination temperature after quenching in liquid nitrogen, stress induction and isothermal aging at 25$0^{\circ}C$is also explained by the transformability of tetragonal phase determined by the sum of particle size effect and constraint effect.

In this study, the Department of Library & Information Science's Students are including their cognitive for the employment prospects of library information, it wants to know satisfaction with current curriculum, job preparation, and requirements for job - related programs. The result, first of all, the students of the field of employment hope was that the library was the field of employment and the public library was the highest one of them. Second, areas of employment were that the Seoul Gyeonggi-do Province showed the highest regardless of the location of the university. Third, the satisfaction of the university curriculum is high, It appeared to be desirable that was field - based employment program. Fourth, The difficulty in preparing for employment was the lack of employment information. Fifth, The factors influencing job choice were working conditions, retirement benefits, welfare benefits, and remuneration. Therefore, to increase the employment rate of students, it was required by the establishment of job information system, reinforcement of field - based training courses, and improvement of local employment conditions and the environment.

This study aims to outline the characteristics of part-time work among older women and examine what determines whether an older woman is employed part-time. Furthermore, the purpose of this study is to investigate difference between the levels of later life preparation of full-time and part-time workers among older women and to suggest thereby the implications for policy makers to develop program for increasing the quality of part-time employment of older women. The results show that former job significantly influences part-time employment of older women. The findings also indicate that later life preparation of part-time workers, including household income, wage income, and public pension, is significantly lower than those of full-time workers among older women.

The initial purpose of Affirmative Action(AA) in the U. S. was to increase access to, and ensure the equitable distribution of, opportunities for racial minority groups in order to redress past discrimination. Over the last several decades, support for AA has grown and waned as structural, political and social currents have shifted. Most recently, AA in university admissions policy was once again tested as The University of Texas at Austin successfully defended its use of AA in admissions and now faces Supreme Court review concerning the lawsuit. Fisher v. University of Texas at Austin. The purpose of this study is to illustrate the evolution of AA in university admissions reflected on major legal cases for and against it. AA is analyzed from the integrative approach based on the historical institutionalism. l.e., influenced by structure, political dynamics, institutions and critical actors.
