유태균,박두재,장문규 한국물리학회 2018 새물리 Vol.68 No.4

In this study, a temperature sensor was fabricated on a silicon-on-insulator (SOI) substrate by using a semiconductor and microelectromechanical systems (MEMS) process to improve the performance of the temperature sensor. For the fabrication of the silicon membrane substrate, a wet etching method using a KOH solution was utilized. The sensitivity and the response time of the temperature sensor fabricated on a silicon membrane were significantly improved compared to those for a temperature sensor manufactured on a slide glass. The thermal response characteristics were analyzed by using Fick's second law modeling. The reaction speed of the sensor on a silicon membrane was improved by about a factor of five and its sensitivity by a factor of four compared with the values for the sensor on a slide glass substrate. 본 연구에서는 온도 센서의 성능 개선을 위하여 반도체 및 미세전자기계시스템(microelectromechanical systems, MEMS) 공정을 이용하여 실리콘 온 인슐레이터(silicon on insulator, SOI) 기판상에 온도 센서를 제작하였다. 실리콘 멤브레인 기판의 제작은 KOH 수용액을 이용한 습식 식각 방법을 사용하였다. 슬라이드 글라스에 제작된 경우와 비교하여 실리콘 멤브레인에 제작된 경우에서 온도 센서의 감도와 반응 속도가 크게 향상되었다. 열 반응 특성은 열 확산 법칙인 Fick's second law 모델링을 통하여 해석하였으며 슬라이드 글라스와 비교하여 반응 속도는 약 5배, 민감도는 약 4배 개선됨을 확인하였다.

지역사회복지관의 욕구조사실태에 관한 연구 : 서울시 소재 84 개 지역사회복지관을 대상으로 한 탐색적 고찰 An Exploratory Investigation on 84 Community Social Welfare Centers in Seoul Area

유태균 한국사회보장학회 2000 사회보장연구 Vol.16 No.1

In recent years, the importance of need assessment as an essential tool for improving the performance and accountability of social welfare agencies has been increasingly recogruzed. Yet, little has been known regarding the capability of social welfare agencies including the community social welfare center to assess community and client needs for services. In this study, a total of 84 community social welfare centers in Seoul area are examined in order to empirically investigate the capability of the community social welfare center to conduct reliable need assessment. In doing so, emphases are on whether community social welfare centers conduct need assessments at all and, if they do, on a regular basis as well as on the quality of need assessment and on the degree and mode of utilization of need assessment result. The study results show; 1) although nearly all community social welfare centers examined conduct need assessment in one way of another, only few conduct it on a regular basis or frequently; 2) most of the community social welfare centers examined are not capable of conducting reliable need assessment; and, as a result, 3) the degree that need assessment results are utilized for the operation of community social welfare centers is in general very low. Based on the study findings, a few policy implications are drawn. One of them is that prior to -or at least along with- the institutionalization of the evaluation of the performance of community social welfare centers, it is imperative to make serious policy efforts to create conducive environment for community social welfare centers to increase the capability of assessing community and client needs for services in a more reliable manner and, thus, to improve their accountability.

유태균,김재은 한국체육철학회 2009 움직임의철학 : 한국체육철학회지 Vol.17 No.2

The purpose of this research is in exploiting the internal emotions experienced by a professional dancer upon employment in a dancing group, reasons for retirement through a dance career, the state of mind at that time and the feelings towards life after retirement. In order to achieve this objective, the following conclusion has been obtained through one of the qualitative research methods, or precedence research method, on those retirees, who had danced for more than 5 years in professional groups. First of all, dancers do feel some level of pride in their profession, but also feel that they are living like a robot, who dance regardless of their will due to the schedule. Secondly, the reasons for deciding to retire were shown to be injuries, which prevent them from continuing their dance career, economic hardship and insecurity for their future. Thirdly, upon deciding to retire, dancers were afraid of the fact they have to look for another job, while feeling relieved from quitting the austere life in dance groups. Fourthly, dancers face their retirement without a real preparation after their careers in dance groups. Finally, dancers pursue jobs that are relevant to dancing after retirement, however, due to insecurity from and unfamiliarity with their current jobs, they fall victims to nostalgia for their previous careers, resulting in identity crisis. 본 연구의 목적은 직업 무용수가 직업 무용단 재직 당시 생활을 통해 느끼는 내면적 감정과 직업 무용단을 은퇴를 하게 된 요인 및 은퇴 당시 심경을 알아보고 은퇴 후 삶에 대해 느끼는 감정을 탐색하는데 있다 . 이러한 연구의 목적을 달성하기 위해 직업 무용단 재직 경력 5년 이상 되는 은퇴 무용수 5명을 대상으로 질적 연구방법 중 사례 연구방법을 통하여 다음과 같은 결론을 얻었다. 첫째, 무용수들은 직업 무용단에 재직하며 무용인으로서 자긍심을 느끼지만 직업 무용단의 짜여진 스케쥴로 인하여 자신의 의지와는 상관없이 춤추는 로봇과 같은 생활을 한다고 느끼고 있었다. 둘째, 무용수들이 은퇴를 결정하는 요인은 직업 무용단 생활을 하며 부상을 입게 되어 무용수로써의 생활을 지속해 나갈 수 없는 것과 경제적 어려움 및 미래에 대한 불안감으로 은퇴를 결정하는 것으로 나타났다. 세 번째로 무용수들은 은퇴 결정 당시 직업 무용단의 고된 생활을 그만두는 것에 대해 후련함을 느끼면서도 새로운 직업을 찾아야 한다는 것에 두려움을 느끼고 있었다. 네 번째로 무용수들은 직업 무용단 생활을 하며 은퇴에 대한 준비를 미처 하지 못한 채 은퇴를 맞이하게 된다. 마지막으로 무용수들은 은퇴 후 무용과 연관된 직업에 종사하고 있지만 전환한 직업에 대해 불안감과 낯설음으로 예전의 직업 무용수 시절을 그리워하며 정체성의 혼란을 겪고 있었다.

유태균,최윤정,노경일 한국체육철학회 2010 움직임의철학 : 한국체육철학회지 Vol.18 No.1

This study aims to look into male dancers’ feminine images in Korean and Japanese traditional dances. To attain the goal of the study, the researchers made a comparative study on talchum and kabuki, respectively Korean and Japanese traditional dances. In the first place, the researchers analyzed Korean and Japanese patterns of directing with a view to looking into their separate feminine images in their respective traditional dances. In the second place, the researchers analyzed their directing methods on the basis of the analyzed patterns of directing. And the researchers in turn analyzed directing methods by dividing them into stage, makeup and costume, and music. As a result, the findings of the research were as follows: First, Korean and Japanese male dancers’ feminine patterns of directing were categorized into court dance, ritual dance, artistic dance and folk dance in both of them. Second, as a consequence of Korean and Japanese male dancers’ feminine patterns of directing being divided into stage, makeup and costume, and music, the Korean male dancers were free and informal in their characterization with no stereotyped stages, with comical makeups, and with no special costumes creating feminine images, while on the contrary the Japanese male dancers were expressing their feminine images better with stereotyped stages, with diverse facial expressions and makeups, with costumes creating feminineness nicely, and with formal and regular patterns of music and dances. 이 연구는 한국과 일본의 전통무용 속에서 볼 수 있는 남성무용수에 대한 여성이미지를 알아보는데 목적이 있다. 이러한 연구의 목적을 달성하기 위해 한국과 일본의 전통무용인 탈춤과 가부키(歌舞伎)를 중심으로 비교 연구하였다. 우선, 한국과 일본의 전통무용에서 나타나는 여성이미지를 알아보기 위해 연출 유형을 분석하였고 다음으로, 분석된 연출 유형을 토대로 연출 방법을 분석하였다. 연출 방법은 무대, 분장 및 의상, 음악으로 나누어 분석하여 다음과 같은 결론에 도달하였다. 첫째, 한․일 남성무용수에 의한 여성적 연출 유형은 한․일 모두 궁중무용, 종교의식무용, 예능무용, 민속무용으로 나타났다. 둘째, 한․일 남성무용수에 의한 여성적 연출 방법은 무대, 분장 및 의상, 음악 및 무용형태로 나누어 본 결과 한국은 정형화된 무대가 없고 우스꽝스러운 분장과 여성적 이미지를 연출하기 위한 특별한 의상 없이 자유롭고 비형식적인 특징을 지닌 것으로 나타났다. 반면 일본은 정형화된 무대와 다양한 표정의 분장, 여성스러움을 잘 표현할 수 있는 의상이 있으며 형식적이고 고정적인 음악과 무용형태를 지니고 있는 것으로 나타나 남성무용수에 의해 여성이미지를 표현하고 있다.

Networking is of great concern for community social welfare agencies (social welfare agencies, henceforth) facing an uneasy task of addressing the complex welfare needs of community with limited resources. Notwithstanding its importance, networking among social welfare agencies has never been empirically studied up to date, and, as a result, the lack of knowledge on this subject is apparent. In realizing this lack of knowledge, this study attempts to empirically examine the networking among social welfare agencies in Seoul Area. In addition, the determinants of the centrality of individual social welfare agencies in the network are also investigated. Data analyses show 1) that networking among social welfare agencies is relatively active in those cases where the objects being exchanged through the network require low exchange cost, that is relatively less efforts for negotiation or bargaining between social welfare agencies; 2) that the degree of networking among agencies varies in terms of the objects being exchanged; and 3) that the centrality of individual agencies in the network depends only on the years in operation and the degree of financial independency of the agency. Based on these and other findings, one of the conclusions that can be drawn is that at present, social welfare agencies are engaging in networking yet in a very timid manner. Some suggestions are made for the promotion of networking among social welfare agencies as a means to increase the efficiency in the utilization of limited resources.

전이 금속 이칼코겐화합물 전계효과 트랜지스터와 2차원 단층 실리콘 전계효과 트랜지스터의 소자 특성 비교 연구

유태균,황신애,장문규 한국물리학회 2017 새물리 Vol.67 No.10

We performed simulations to analyze the characteristics of a transition-metal dichalcogenide field-effect transistor (TMD FET) and an ultra-thin-body field-effect transistor (UTB FET) using a MoS$_2$ mono layer and a silicon mono layer as channel materials. The gate voltage, the characteristics of the drain current, and the subthreshold swing were analyzed by varying the channel thickness and the oxide thickness, and the channel thickness and the oxide thickness became smaller with decreasing short-channel effect. Based on the simulation result that the thicknesses of the channel and the oxide layers should be about 1 nm, we compared the optimal characteristics of the transistor using a thin channel with each other for the TMD FET and the UTB FET. The subthreshold swing value of the TMD FET is better than that of the UTB FET. 단층 MoS$_2$와 단층 실리콘을 채널 물질로 사용한 2차원 트랜지스터(transition metal dichalcogenide field-effect transistor, TMD FET)와 극박막 트랜지스터(ultra-thin body field effect transistor, UTB FET)의 소자 특성 분석 시뮬레이션을 진행하였다. 2차원 트랜지스터와 극박막 트랜지스터의 채널과 산화막 (oxide) 두께를 변화시켜가며 각 각의 게이트 전압과 드레인 전류의 특성과 서브 스레숄드 스윙(subthreshold swing) 등을 분석하였으며, 채널과 산화막 두께가 얇을수록 단채널 효과가 줄어든다는 것을 알 수 있었다. 얇은 채널을 사용하는 트랜지스터의 최적 구동 조건은 채널과 산화막 층의 두께가 1 nm 정도 되어야 한다는 시뮬레이션 결과를 바탕으로 2차원 트랜지스터와 극박막 트랜지스터의 소자 특성을 상호 비교해 보았으며 2차원 트랜지스터의 서브 스레숄드 스윙 특성이 더 좋다는 것을 확인할 수 있었다.
