The power capacitors used as vehicle inverters must have a small size, high capacitance, high voltage, fast response and wide operating temperature. Our thin film capacitor was fabricated by alumina layers as a dielectric material and a metal electrode instead of a liquid electrolyte in an aluminum electrolytic capacitor. We analyzed the micro structures and the electrical properties of the thin film capacitors fabricated by nano-channel alumina and metal electrodes. The metal electrode was filled into the alumina nano-channel by electroless nickel plating with polyethylene glycol and a palladium catalyst. The spherical metals were formed inside the alumina nano pores. The breakdown voltage and leakage current increased by the chemical reaction of the alumina layer and $PdCl_2$ solution. The thickness of the electroless plated nickel layer was 300 nm. We observed the nano pores in the interface between the alumina layer and the metal electrode. The alumina capacitors with nickel electrodes had a capacitance density of 100 $nF/cm^2$, dielectric loss of 0.01, breakdown voltage of 0.7MV/cm and leakage current of $10^4{\mu}A$.

High interest in well-being due to increased income and more ego-centric attitudes have brought about new life style. But the other side, an increase in undergrounded anxieties about weather disasters, crime, terrorist attacks has compromised the public`s sense of security. Ubiquitous IT(u-IT) is characterized by terms ``real``, ``connected``, ``invisible`` and ``calm``. u-IT enabled all objects to have computing power and allows their use anytime and anywhere through networking. Therefore, u-IT is able to provide more convenient and safe living conditions by delivering autonomous services based on advanced intelligent system. The goal of this paper is to study on cases, various contributions and strategies of u-IT for safe society.

The purpose of this study was to examine the effects of sex role identity and the interest in the opposite sex of high school male students on the appearance management attitude. For this purpose, questionnaire was administered to 600 high school male students selected from four high schools located in Gwangju from November 18 to 21, 2005. Data from 574 participants were analyzed using SPSS 12.0. Factor analysis, ANOVA, Duncan-test, t-test, x2-test and the descriptive analysis were used to analyze the data. The results were as follows. 1. The differences of the appearance management attitude according to the sex role identity show that androgynous group has a positive attitude to clothing, body, face and hair care, whereas undifferentiated inclination group has the less positive attitude. 2. The boys’ highschool students who have less interests in the opposite sex are the most positive to the appearance management attitude and particularly to the clothing care and there is a clear distinction between the students with much interests and little. 3. The interaction between the sex role identity and the interests in the opposite sex has a similar effect on clothing, face and hair care, and among the students who have androgynous and great interests in the opposite sex show more positive attitudes. 4. It appears that academic high school students are more positive to the appearance making attitude, especially to the clothing care than vocational high school students. The students, moreover, who are seeing someone(or have once before) take up more positive attitudes to the appearance than others.
보문 : 외모에 대한 사회문화적 영향과 신체이미지가 외모향상추구행동에 미치는 영향

This study investigates the effects of sociocultural influences and body image on appearance enhancement behaviors (facial management, clothing selection, and weight/figure management). For data collection, a questionnaire was administrated to 562 female college students in Gwangju City, Chonnam area and Chonbuk area, Korea, from May 23 to June 10, 2011. To analyze the data, a SPSS 18.0 statistics package was used, and descriptive statistical analysis, frequency analysis, factor analysis, reliability analysis, and regression analysis were conducted. The results were as follows. First, sociocultural influences were divided into three factors: parental influence, media influence, and peer influence. Overall sociocultural influences had positive effects on appearance enhancement behavior. Second, body image was divided into two factors: weight-concern and appearance-concern. Sociocultural influences had significant effects on overall body image. Third, body image appeared to have positive effects on overall appearance enhancement behavior.

This study investigates the effects of socicultural influences of appearaned(parental influence, media influence, peer influence) on body dissatisfaction and appearance enhancement behaviors(clothing selection, skin care, male-up, hair care, weight management). For data collection, a questionnaire was administrated to 562 female college students in Gwangju, Chonnam area and Chonbuk area, Korea, from May 23 to June 10, 2011. To analysis the data, descriptive statistical analysis, factor analysis, regression analysis, and path analysis were conducted. The results were as follows. Firs, the overall effects of sociocultural influences of appearance on body enhancement behavior turned out to have positive effects. Second, overall sociocultural influences of appearance had positive effects on body dissatisfaction. Third, the overall effects of body dissatisfaction on appearance enhancement behavior did not appear to be statistically significant. Forth, the effects that sociocultural influences of appearance on appearance enhancement behavior mediated body dissatisfaction appeared to be insignificant.
공공부문 소셜미디어 실효성 제고를 위한 4대 활용 전략 및 부작용 대응 방안 연구
박선주(Park Seon Ju),정명선(Jeong Myung Sun) 한국통신학회 2012 한국통신학회 학술대회논문집 Vol.2012 No.6
IT의 발달과 스마트 기기의 대중화로 실시간성이 강화되면서 소셜미디어는 대표적인 뉴미디어로 각광받고 있다. 하지만 공공부문의 무분별한 도입과 실효성 낮은 활용, 그리고 소셜미디어 부작용에 대한 우려가 커지고 있다. 이에 본고에서는 주요국의 정책과 사례분석을 통한 성공적인 활용전략과 로드맵, 체계적인 부작용 유형분석을 통한 정책적 대응방안을 제시하고자 한다.
