As aging occurs, ow skin gets more wrinkles, becomes drier and loses its elasticity. Validating the evaluation of skin elasticity is especially important, because it is not as visible as other signs of aging such as wrinkles. Here, we identified the correlation between age and the Parameters given by Cutometer, and (we present) the parameters of that reflect the decreases in skin elasticity along with ages (Ur/Uf, Ua/Uf, Ur/Ue, Ua, $r=0.687{\sim}0.725$). Also we developed an evaluation method to quantify the difference of skin by viewing or touching. A five-grade standard of Moire topographic photo scale on face was prepared using sensory evaluation of 20 to 61 year - old women. Based on this photo standard, scoring was performed using (a) 5-grade system by three specialists to obtain the consensus score. Significant negative correlations between age and results of Cutometer $(r=-0.687{\sim}-0.725)$, Moire topography scores (r=-938) were found. Finally we have shown the significance of the correlation between the result of Cutometer and the score of Moire topography (r=0.711). Our studies using Moire topography on face have confirmed that instrumental measurements reflect the decrease in shin elasticity, which is perceived visually.

The aim of this study is to examine the mediating effects of the social support and ego-resilience of adolescent counselors on the relationship between their job stress and burnout. The subjects of this research exercise comprised 250 adolescent counselors. Data were analyzed by means of Pearson's correlation and by structural equation modeling. The results were as follows. First, there was a positive correlation between job stress and burnout, and job stress had a negative correlation with social support and ego-resilience of the adolescent counselors. Moreover, social support and ego-resilience had a negative correlation with burnout. Second, social support did not have any direct impact on relieving burnout yet affected it in an indirect way through ego-resilience. Ego-resilience exerted both direct and indirect influence on reducing burnout. Therefore, it was found that the ego-resilience of the adolescent counselors was bound up with their job stress and there by exercised a significant influence on burnout. The findings of the study illustrated that as for the relationships among the job stress, social support, ego-resilience and burnout of the adolescent counselors, ego-resilience was a crucial variable in preventing burnout. This study is of significance in that it provided theoretical data which can be used when developing programs designed to prevent burnout in adolescent counselors.

The purpose of this study was to investigate the relationship between university life satisfaction and resilience to happiness and university life satisfaction. The subjects of this study were 249 pre-service early childhood teachers in Seoul and Gyeonggi province. The statistical analysis of this study was analyzed using the SPSS V. 22.0 program. The results of the study are summarized as follows. First, pre-service early childhood teachers' perceived resilience, happiness, and University life satisfaction were generally considered to be 'normal'. Second, the relationship between the resilience and happiness of pre-service early childhood teachers showed that the higher the resilience, the higher the level of happiness. Also, resilience showed statistically significant effect on happiness and 69% of happiness. Third, the relationship between resilience of pre-service early childhood teachers and university life satisfaction showed that the higher the resilience of resilience, the higher the satisfaction of University life. Also, resilience showed a significant effect on university life satisfaction and 68% of happiness. This study is meaningful in that the resilience of pre-service early childhood teachers proves to be an important factor in the happiness and the University life satisfaction, which are related to quality of life of pre-service early childhood teachers.

The presnt study reviewed two contrasting models, fixed-resolution slot versus flexible-resource hypotheses, for the representational characteristics of visual working memory (VWM), and emphasized the necessary efforts for resolving their conflicting arguments. To accomplish this goal, the review explored the background hypotheses of the object-based versus parallel independent storage models, and introduced theoretical bases for their contrasting claims. The review then evaluated validity of empirical evidence provided in the studies to support each model, and attempted an understanding of their neurophysiological background. The study further emphasized the necessity of theoretical and methodological reconsiderations to resolve their conflict as well as the necessity of obtaining converging pieces of evidence to accomplish the resolution.

우리 국민의 교통수요행태를 분석하기 위하여 준이상수요체계(almost ideal demand system) 함수형태의 집계교통수요모형을 설정하였다. 대중교통수단으로서 시내버스, 시외버스, 택시, 기차, 전철이 그리고 개인교통수단으로서 연료비가 포함되었으며, 기타재화 및 서비스에 대한 소비지출이 함께 추정되었다. 추정에 이용된 자료는 통계청의 "도시가계연보"에 수록된 '전국 도시가구 소비지출'과 "물가통계"에 수록된 '전국 도시소비자 물가'이다. 추정결과 모형의 설명력을 나타내는 수정결정계수(adjusted-$R^2$)는 대부분 0.9 내외에서 높게 나타났다. 추정계수는 총 51개중에서 25개가 5% 수준에서 유의한 것으로 나타났다. 추정된 계수값을 이용하여 가격탄력성과 소득탄력성을 구하였다. 자기가격탄력성과 소득탄력성 추정치는 조금 높기는 하나 부호와 상대적 크기가 모두 예상과 일치하고 다른 연구결과들과 유사한 범위에 있다. 연료비에 대한 소득탄력성은 1.72로 가장 높게 나타났고, 대중교통수단은 0.03~0.49 사이에서 나타나므로 교통수단이 정상재임을 의미한다. 보상수요의 교차가격탄력성은 총 15개의 교차관계에서 12개의 관계가 상식과 일치한다. 다음 연구에서는 더 많은 시계열자료를 발굴하여, 장기간의 교통수요 변화에 대한 분석을 시도할 필요가 있다. 또한 초월대수함수나 동태함수 등 다양한 형태의 수요함수를 시도할 필요가 있다. 여러가지 형태의 교통수요함수추정을 통해서 우리 현실에 적합한 교통수요모형을 발견할 수 있을 것이다. 대도시와 중소도시 등 지역별 지출자료를 발굴하여 지역특성을 반영하는 교통수요함수의 추정도 필요하다.

A survey was conducted to 699 middle school students who live in Seoul area. The results showed significant correlations among social support, Self-concept and Ego-resilience. Most importantly, the variable of Self-concept was stronger predictor for Ego-resilence than Social support.

The hypothesis that the common market equilibria for housing attributes are attained within distinctive submarkets was tested. Markets for housing attributes with greater supply flexibility, i.e., structural variables, were found to be closer to their common equilibria than markets with less supply flexibility, i.e., neighborhood and distance variables. In addition, submarkets with greater mobility were found to achieve common market equilibria for more housing attributes with greater supply flexibility, but not for housing attributes with lower degree of supply flexibility. Results suggest supply flexibility and occupier mobility are both necessary conditions for achieving common market equilibria for housing attributes.

An 81-year-old woman was admitted to our hospital with bilateral chest wall mass in the infrascapular region. Considering the possible diagnosis of a malignant chest wall tumor at such location, we performed excision and biopsy. Both masses were histologically diagnosed as elastofibroma. We experienced this rare disease, bilateral elastofibroma, so we report this case with a bibliography.

본 연구의 목적은 균형에 이상이 있는 20대 정상 성인에게 혈류제한성 탄력밴드 훈련 적용 시 균형능력 회복에 미치는 효과를 알아보고자 하였다. 12명의 남성을 대상으로 대조군(n=6), 실험군(n=6)으로 무작위할당하였다. 두 군은 고강도 축구경기를 통한 균형능력 손상 유발 후 실험군은 1주일 3회 1시간씩 4주 동안 혈류제한성 탄력밴드 훈련을 실시하였고, 대조군은 아무런 훈련을 실시하지 않았다. 모든 대상자는 경기 전, 경기 후, 경기 4주 후에 정적 및 동적 균형을 측정하였다. 연구 결과, 정적균형에서 대조군은 경기 전으로 유의한 회복을 나타내지 않았으나, 실험군은 유의한 회복을 나타냈다. 동적균형에서는 대조군과 실험군 모두에서 유의한 회복을 나타냈다. 혈류제한성 탄력밴드 운동은 단기간에 효율적으로 근력을 향상시킴으로써 균형능력 회복에 긍정적 영향을 줄 수 있다고 판단된다.
