The youth-pursing syndrome is especially amplified through a variety of media due to medical technology development, increases in social activities, and influence. This study discusses the relationship of youth-pursuing, media appearance information interest, and media contact responses focused middle-aged women. Data were collected from 245 females aged 40-65 in Seoul, Daejeon and Chungbuk area residents. The SPSS WIN 21.0 program analyzed the data by descriptive statistics, factor analysis, and regression analysis. Youth-pursuing derived social, psychological, and outward factors. Only an outward factor of these three dimensions influenced a significant media appearance information interest, and media contact response. The regression analysis results for chronological age and cognitive age, cognitive age influenced all variables significantly (three factors of youth-pursuing, media appearance information interest, and media contact response). But chronological age influenced significantly only the media appearance information interest. This study verified the relationship of youth-pursuing and media variables (media appearance information interest and media contact response).

This study examined difference of purchase behavior of appearance orientation, appearance evaluation, and fashion product purchase behavior on media contact responses. Data were collected from 315 female Chinese university students in Daejeon and Chungnam from May to June 2013. Data were analyzed by descriptive statistics, t-test, correlation, crosstabs analysis with the SPSS-WIN 20.0 program. The results of this study were as follows. First, media contact responses correlated appearance orientation and appearance evaluation. The active group of media contact responses indicated a more active appearance orientation and appearance evaluation. Second, the active group of media contact responses were fashion product purchase behavior. This study verified the relationship of media contact responses and appearance variables-appearance orientation, appearance evaluation, and fashion product purchase behavior.

The purpose of this study was to investigate the appearance orientation and clothing and cosmetics purchasing behaviors according to media contact responses. The subjects were 445 female university students in Daejeon and Chungnam province. The measuring instruments was a questionnaire with media contact responses, appearance orientation, clothing and cosmetics purchasing behavior, and subjects' demographic characteristics. The data were analyzed by Cronbach's ${\alpha}$, frequency analysis, ${\chi}^2$ test, ANOVA, Duncan's multiple range test, and regression analysis using SPSS program. The results were as follows. First, female university students had very positive response and attitude on entertainers' appearance, style and products showed by media. Second, media contact response had a significant effect on appearance orientation. The group with a high level of media contact response showed higher appearance orientation than the groups with mediate and low level of media contact response. Third, media contact response had meaningful effects on clothing and cosmetics purchasing behaviors. The group with a high level of media contact response showed higher shopping frequency, purchasing frequency, and more spending on clothing and cosmetics than other groups.

본 연구에서는 적외선 카메라 기반의 비접촉식 측정 방법을 이용하여 동공 반응 데이터를 수집하여 공감의 사회감성을 객관적이고 정량적으로 추정하는데 그 목적이 있다. 실험에는 10명(남 6명, 여 4명, M ± SD = 24.17 ± 2.16세)의 피험자가 참여하였다. 30초의 참조 데이터 측정 후, 공감 유무에 따라 과제는 얼굴 표정 모방 과제와 얼굴 표정 자발적 표현 과제로 구분되어 두 사람은 표정으로 상호작용하였고, 2번씩 반복 진행하며 적외선 카메라를 통해 동공을 촬영하였다. 이진화 및 원형 윤곽선 검출법의 영상처리를 활용하여 동공 데이터를 수집하였고, 이동 평균 기법을 활용해 눈깜빡임 노이즈를 제거하고 동공 크기 개인차로 데이터 표준화를 진행하였다. 공감 유무에 따른 동공 크기 데이터는 정규성 검증 및 독립표본 t검정을 통해 통계적 유의성을 확인하였다. 분석결과, 공감하는 경우(M ± SD = 0.508 ± 1.278)와 공감하지 않은 경우(M ± SD = 1.681 ± 0.968) 동공 크기가 통계적으로 유의미한 차이를 보였다(t(18) = -2.313, p = 0.033). 판별분석을 통해 동공 크기에 따른 공감의 유무를 추정하는 규칙을 정의하였다. 본 연구에서 제안한 동공 크기 데이터를 이용한 공감의 사회감성 추정 기술은 비접촉식 카메라 기반의 기술로 스마트 글래스와 접목되어 다양한 분야에 활용도가 높을 것으로 기대된다.

폴리우레탄, 폴리에스테르, 바이페놀, PVC 외 각종 농약 등을 생산하는 울산의 모 화학공장에서, 다양한 종류의 휘발성유기화합물질들(VOCs)이 배출되고 있다. 평균적인 휘발성유기화합물질의 배출 농도는 7283 ppm으로, 톨루엔, 페놀을 포함하여 Trimethyl-pentene, trimethyl-hexene, dimethyl-cyclohexane 등이 검출되었다. Trimethyl-pentene, trimethyl-hexene, dimethyl-cyclohexane등은 인화성이 강하며 화재를 일으킬 위험성이 매우 큰 것으로 알려져 있고, 특히 톨루엔과 페놀의 경우는 호흡이나 피부접촉 등을 통한 인체로의 유입이 있을 경우 유독성을 나타내게 된다. 이러한 VOCs제거를 위하여 겨울철 기간에 파이로트-규모의 바이오필터 적용 실험이 진행되어 졌다. 본 연구의 목적은 바이오필터 운영이 진행되는 가운데 온도, 함수비, 하중, 압력손실 등의 제한요소들이 미디어 내부에서 변화하는 상황에 대한 관찰 및 평가에 있다. 이러한 제한요소들은 바이오필터의 디자인과 오염물질 제거에 심대한 영향을 미치게 된다. 바이오필터는 옥외에 설치되어 총 44일간 운영되어 졌는데, 외부 영하온도의 영향을 최소화하기 위하여, 7cm두께의 파이버-글래스 소재 단열설비가 반응기 외부에 설치되었고 또한 $150^{\circ}C$의 스팀이 바이오필터 반응기와 단열설비 사이에 제공되어 졌다. 바이오필터 반응기 내부에는 23개의 온도 측정 센서와 함수비 센서, 공기샘플포트, 습도계 등이 각기 다른 장소에 설치되어 온도, 함수비 등의 제한요소 영향연구가 진행되었다. 미디어 내부 같은 높이의 서로 반대되는 위치에서 온도차가 13.7도에서 -8.3도까지 차이가 나는 것으로 관찰되었으며, 미디어 높이 위치의 변화에 따라서도 21도에서 2도가지 차이를 나타냈다. 바이오필터 함수비는 실험기간 동안 지속적으로 변화가 발생하였는데, 스팀이 제공되는 동안에는 미디어 함수비가 훨씬 빠른 속도로 증가됨이 관찰되어 졌다.

This study aims to objectively and quantitatively determine the social emotion of empathy by collecting pupillary response. 52 subjects (26 men and 26 women) voluntarily participated in the experiment. After the measurement of the reference of 30 seconds, the experiment was divided into the task of imitation and spontaneously self-expression. The two subjects were interacted through facial expressions, and the pupil images were recorded. The pupil data was processed through binarization and circular edge detection algorithm, and outlier detection and removal technique was used to reject eye-blinking. The pupil size according to the empathy was confirmed for statistical significance with test of normality and independent sample t-test. Statistical analysis results, the pupil size was significantly different between empathy (M ± SD = 0.050 ± 1.817)) and non-empathy (M ± SD = 1.659 ± 1.514) condition (t(92) = -4.629, p = 0.000). The rule of empathy according to the pupil size was defined through discriminant analysis, and the rule was verified (Estimation accuracy: 75%) new 12 subjects (6 men and 6 women, mean age ± SD = 22.84 ± 1.57 years). The method proposed in this study is non-contact camera technology and is expected to be utilized in various virtual reality with smart glasses.
