On entering the industrial society, our society faced with the aging society due to the nuclear family and the extention of the average life expectancy. The objectives of the study were to review the problems and to suggest the strategies for the aged employment. The main findings from the study were as follows: 1) It has been inevitable to utlize the aged laborer since 1970s due to increasing life expectancy and changing attitude toward supporting of the aged. 2) Though life expectancy has been increased, the retiring age of laborer is more or less the same with that of 1960s. However, the majority of the aged is poor and the rate of the aged employment is very low. 3) The aged have reasons that they want to be employed, the reasons are, ①for making living expenses ② for enjoying working ③ for the health ④ for overcoming loneliness. 4) The kinds of job for the aged is varied. The aged can work all kinds of job except hard working by the young. 5) The enterprise shrink the aged employment due to the high wages, the lack of adaptability to new technoligy, and the weak of mental and physical function. 6) Compared with the young, the aged is lower in productivity, nevertheless, there is no evidence of differences in sincerity and responsibility. 7) Self-reliance effort by the aged for the aged employment is very weak and studies and polices by the government for the aged employment is very low. 8) The structure of population is changing. So, studies and policies by the government for the aged employment and self-reliance effort by the aged should be implemented. Based in the findings of the study, the followings should be carried out to enhance the aged employment. 1) Reducing the enterprise burden by improving seniority wage system for the extension of the retiring age. 2) Recommendating the aged re-employment by considering the will to work, the health and the work results of the aged. And giving the chance to work by the part time work and the contract work. 3) Growing technology ability by giving the chance of occupational tranning to the aged having the will to work. 4) Establishment of relevant policy institutions for the aged employment, and carring out the promotion law of the aged employment. 5) Supporting to enterprises employing the aged by taxing system. 6) Supporting to the the aged welfare factory and the aged industries for managing themselves. 7) Making the benefit system to households of supporting his the aged. 8) Widening the aged pansion.
Surface oxidation in a van der Waals ferromagnet Fe3-xGeTe2

We investigate the surface oxidation in a van der Waals ferromagnet Fe3-xGeTe2, a material widely utilized for spintronic applications. While known for its relative air-insensitivity, exposure to air during the handling process (e.g. device or heterostructure fabrication) can lead to reduction or disappearance of its magnetic signal. Comparison of x-ray absorption and x-ray magnetic circular dichroism spectra between pristine and air-exposed Fe3-xGeTe2 confirm a naturally oxidized surface layer on the material. The surface oxide layer has predominantly Fe3+ content. X-ray absorption spectroscopy done on micron-sized exfoliated Fe3-xGeTe2 flakes reveal that the change in the surface chemical properties can be quite significant for thin flakes. The surface modulation of Fe3- xGeTe2 can lead to inaccuracies in characterizing its interfacial magnetic and spin transport properties, and complicate device and heterostructure fabrication processes.
사람들의 사회학으로서의 Ethnomethodology에 대한 탐구

In this essay, I come to regard the following as a starting point of my research, an issue raised by a researcher, a student of Ethnomethodology, suggesting that the term Ethnomethodology be translated as 'the sociology of Men', rather than 'Minsokbangbeopron', the term used by the researchers in Korea. In this work, firstly, I attempted to understand how Harold Garfinkel, who coined the term Ethnomethodology, defined 'ethno', and 'methodology', and what the implications of his perspective are to us, and to understand what's the difference between the existing sociology and Ethnomethodology on the basis of the literature and my own experience. Secondly, by examining an empirical study by Garfinkel, I attempted to grasp what implications an empirical study based on EM may give to qualitative research. In this work, firstly I came to identify that EM is a new sociology that rejects the revisionism in which the existing sociology argues that everyday language or concept should be translated into scientific language or concept because it is ambiguous. Secondly, I came to realize what kind of things a researchers should focus on in the field with Ethnomethodology's perspective. Thirdly, I came to identify some attempts of the researcher who suggested the necessity of translating liberally the term Etho into Men and the term Ethomethodology into the sociology of men and research inquiring into the sociology of men. 이 글에서 나는 Ethnomethodology가 한국의 학계에서 유통되고 있는 번역어인 민속방법론이라는 직역 대신 ‘사람들의 사회학’이라고 의역이 필요하다는 어느 연구자의 문제제기를 진지하게 받아들이고 검토하는 것을 연구의 출발점으로 삼았다. 이 연구를 수행하기 위해, 나는 먼저 EM의 창시자인 Garfinkel(H. Garfnikel)이 EM이라는 개념을 어떻게 만들었고, 그 개념을 통해 무엇을 밝히려고 하였는지 나아가 EM이 규범주의 사회학과 어떻게 차별화 되는지를 문헌 연구와 나의 경험을 통하여 추적하였다. 둘째, Garfinkel이 수행한 실제 연구를 검토함으로써 EM의 발상에 기초한 연구가 질적 연구에 주는 시사점을 엿보고자 하였다. 연구 결과, 첫째, EM이 일상언어 혹은 개념을 애매하다는 이유로 과학언어 혹은 개념으로 번역해야 한다는 규범주의 사회학에서 나온 수정주의를 지양하는 새로운 사회학임을 확인할 수 있었다. 둘째, EM의 입장에 섰을 때 질적 연구자는 필드에서 무엇을 연구대상으로 삼아야 하는지를 밝혔다. 셋째, Ethno를 사람이라고 의역하고 EM을 사람들의 사회학 그리고 그 사람들의 사회학을 연구하는 학문으로 의역할 필요성을 제기한 그 연구자의 시도가 일리가 있다는 것을 확인할 수 있었다.
