Migration-enhanced epitaxy 성장한 InAs/GaAs 양자점(quantum dots)의 광학적 특성을 PL (photoluminescence)과 Time-resolved PL 이용하여 분석하였다. InAs 양자점은 In을 9.3초 공급하고 5초 차단한 후 As을 3초, 4초, 6초, 또는 9초 공급하고 5초 차단하는 과정을 3회 반복하여 성장하였다. As을 3초 공급한 시료의 PL 피크는 1,140 nm에서 나타나고, PL 세기는 다른 세 시료에 비해 매우 약하게 나타났다. As 공급시간을 3초에서 증가하였을 때 모든 PL 피크는 1,118 nm로 청색이동하여 나타났으며, PL 세기는 증가하였다. As을 6초 공급한 시료의 PL 세기가 가장 강하게 나타나고, 반치폭(full width at half maximum)도 가장 좁게 나타났다. 이러한 결과는 양자점의 밀도와 균일도(크기변화)로 설명된다. 또한 발광파장에 따른 PL 소멸시간은 PL 피크 근처에서 가장 길게 나타났다. The luminescence properties of InAs/GaAs quantum dots (QDs) grown by a migration enhanced epitaxy method have been investigated by using photoluminescence (PL) and time-resolved PL measurements. The MEE method supplies materials in a series of alternate depositions with migration enhancing time between each deposition. After In source was supplied for 9.3 s, the growth was interrupted for 5 s. Subsequently, As source was open for 3 (AT3), 4(AT4), 6 (AT6), or 9 s (AT9), and the growth was interrupted for 5 s again. This growth sequence was repeated 3 times for the growth of InAs QDs. The PL peak of the AT3 was 1,140 nm and the PL intensity was very weak compared with that of the other three samples. The PL peak of all samples except the AT3 sample was 1,118 nm, which is blueshifted from 1,140 nm, and the PL intensity was increased compared to that of the AT3. These results can be explained by the increased QD density and the improved QD uniformity. The AT6 sample showed the strongest PL intensity and the narrowest full width at half maximum. The PL decay time of AT6 increased with increasing emission wavelength from 940 to 1,126 nm, reaching a maximum decay time of 1.09 ns at 1,126 nm, and then decreased as the emission wavelength was increased further.

The purpose of the present research was to provide basic materials for groping for the methods that promote adolescents' self-identity through the utilization of the internet. After scrutinizing the actual conditions of adolescents' use of the internet, this study examined the effect of adolescents' family environment, friendships, and use of the internet on their self-identity. Specifically, the present research sought to explore the utilization of the internet by sociodemographic and family environment variables, the effect of background variables on the psychological variable, as well as the relative effects of background variables and the internet-related variables on the psychological variable. The major findings of the study were as follows: The effect of the various variables on adolescents' self-identity showed that the higher the levels of school record, communication with fathers, communication with mothers, intimacy of friendships, and the use of the internet, and the lower the degree of the internet addiction, the higher the level of self-identity. The findings of this research indicate that the level of internet utilization and its addiction among family environment-related variables exerted significant influence on self-identity. This implies that the proper use and guidance of the internet is crucial to adolescents' self- identity, and the use of the internet needs to be guided by families, schools, and communities.

We report a case of left salpingeal serosa tumor with features of Wolffian adnexal tumor. A 36-year-old woman underwent Caesarean section for full term delivery. During operation, a 1cm-sized round mass is found on serosa of left salpinx incidentally. On microscopic examination, the tumor showed mixed pattern of tightly packed tubular structures and difffuse spindle cell proliferation. Immunohistochemical study demonstrated positivity for cytokeratin, vimentin and calretinin, and negativity for inhibin, epithelial membrane antigen, estrogen receptor, progesterone receptor, cytokeratin 20 and inhibin.

The purpose of this study was to investigate clothing socialization in Korean fairy tales by the socialization theory. Clothing socialization analyzed of seven categories-norm, role, self-identity, morality, instituition, social class and social change. From the costume in the korean fairy tales, clothing socialization can be visualized.

Previous studies have consistently shown that adolescents' drinking in Korea has been increasing and that alcohol has been the most widely used substance by them. The purpose of this study was to develop a school-based alcohol prevention program and to evaluate its effectiveness. The program, school-based alcohol prevention program developed based upon the social influence model, is composed of six sessions. The program focused on teaching students various social skills and self-management skills to resist alcohol-related social influences as well as on correcting misconceptions about alcohol. A total of 38 students were participated in this study. The program was conducted in a boys'middle schools which were located in Cheongju. To evaluate the effectiveness of the program, this study compared the scores of pre-post test on the dependent measures including alcohol expectancies and drinking behaviors. Followings are the major findings of this study. First, the findings on alcohol expectancies were consistently lowered, Second, the frequencies of drinking and per month were decreased over time in the experimental group. Third, overall social skills were increased over time. It was concluded that the program was effective in changing adolescents' social skills, alcohol expectancies and their drinking behaviors. Finally this study recommends that school-based alcohol prevention programs like this one should be implemented in order to reduce and prevent adolescents' drinking in Korea.

생산적 복지와 노인고용정책

김미혜 이화여자대학교 사회과학연구소 2001 사회과학연구논총 Vol.7 No.-

본 연구는 이론적 ·개념적 측면에서 노인의 생산적활동과 근로의 의미를 살펴보고 선행연구들을 통해 노인의 인구사회학적 특성과 경제적 특성에 따라 근로의 의미가 구체적으로 어떻게 특징 지워지는가를 밝혀내고자 한다. 또한, 이러한 선행작업을 토대로 노인에게 필요한 고용정책을 유형화하여 노인고용정책의 치용과 현황 및 문제점을 분석한 후 고령자 고용정책의 대안을 제시하고자 한다. 노인의 생산적 활동은 일반적으로 근로를 강조하는 생산적 복지의 이념과는 달리 노인에게 일방적으로 노동을 강제하는 의미로 해석해서는 안되며, 경제적 · 비경제적 활동을 포함하는 의미로 해석되어야 한다. 그리고 이러한 관점에서 노인의 고용정책은 경제적 고용과 사회적 고용을 포괄하는 정책으로 확대되어야 하면,정책 대상자인 노인의 근로능력과 근로욕구 및 연령과 생활수준 등이 고려된 종합적인 정책체계와 세분화된 정책내용으로 이루어져야 한다. 노인 계층은 근로능력, 근로욕구, 연령, 생활수준엔 따라 총 9개 그룹으로 구별될 수 있으며 각각의 그룹의 특징에 따라 경제적 고용정책, 사회적 고용정책, 기초생활보장정책이 제공될 수 있다. 그러나 우리나라의 현 노인고용정책은 근로능력과 근로욕구가 있는 노인을 전제로 한 경제적 고용정책에만 치중되어 있으며, 사회적 고용정책에 대한 부분은 거의 이루어지고 있지 않아 향후의 고령사회에 대비할 수 있는 적절한 노인고용정책이 제시되고 있지 않다. 이상의 분석결과에 따라 우리나라의 노인 고용정책의 개선방향을 제시하면 다음과 같다. 첫째, 경제적 고용정책에 있어서는 근로능력이 있는 노인들의 근로욕구와 경제적 활동 필요성에 대한 판단, 연령, 생활수준등이 고려된 세분화된 정책내용과 서비스들이 제공되어야 한다. 둘째,사회적 고용정책에 있어서는 무엇보다도 노인의 사회참여를 사회적 고용정책으로 수용할 수 있는 사회적 합의와 정책적 제도화가 요구된다. 셋째,경제적 고용정책과 사회적 고용정책의 효과적인 개선 및 운영을 위해 경제적 고용정책과 사회적 고용정책은 통합 운영되어야 한다. The purposes of this study were to review meaning of productive activities and work of the elderly, to search the implication of meaning of work in terms of demographic and economic status among the elderly. Also , based on meaning and implication of work, this study developed the framework grouping the elderly which were applied to analyze current situations and to suggest policy alternatives for elder employment. The concept of productive welfare, so called, workforce should not be applied directly to productive activity for the elderly. In this respect, employment policy of the elderly should include economic employment and social employment. In addition, it should be composed of complex policy system and detailed contents considering working ability, needs for work, age and living standard of the elderly. The level of elderly could be divided into nine groups according to working ability, needs for working, ages, living standards and according to the characteristics of each group, policies can be provided as economic employment, social employment, basic livelihood assistance. But, current employment policies focused on the economic employment rather than social employment. The followings are suggested for the improvement of the Korean elderly's employment policy First, consideration of working ability, needs for work, age, living standards are needed for economic employment policies. Second, Social consensus and systemization for social employment are required. Third, economic employment policies and social employment policies must be carried out together.
