자폐증의 임상증상 완화에 대한 Carbamazepine의 효과를 평가하기 위하여 위약으로 대조한 이중맹(placebo controlled double blind) 연구를 실시하였다. 연구대상 아동은 1989년 10월부터 1991년 11월까지 서울대학병원 어린이병원 소아정신과 외래를 방문한, DSM-III-R의 전반적 발달장애의 진단기준을 만족시키면서, 부모가 연구에 동의한 23명의 남아로 하였다. 또한 다른 내과적 혹은 정신과적 질환력을 갖지 않으며, 연구 시작전 적어도 2개월이상의 약물복용이 없는 기간을 갖도록 하였다. 연구 대상군의 Cabamazepine치료군과 위약군으로 할당을 무작위적 할당표에 의해 할당하였는데, 각각 12명, 11명이 해당되었다. 연구 대상 아동의 상태를 모르는(blind) 2명의 평가자에 의하여, 기초관찰 기간과 12주의 약물치료 기간후에 측정한 검사도구의 측정값의 변화와 약물에 대한 부작용을 보았다. 두 검사자간의 신뢰도는 .4875-.6613이었다. 기초 관찰기간시 두군사이의 사회 인구학적 변인 및 검사도구의 값은 유의한 차이가 없었다. 약물 치료 기간 종결시 측정한 검사도구의 값과 기초 관찰기간의 값을 비교한 결과, Autism Behavior Checklist상 전체 점수의 유의한 차이(P<.05), 즉 Carbamazepine치료군이 위약군보다 자폐증 증상의 완화정도가 큰 소견을 보였다. Vineland Social Maturation Scale에서는 두군 모두에서 약물 치료 기간동안 사회성숙도상의 발달이 유의한 정도(P<.005)로 있었다.

Currently there are many groups of Indonesian faculty members on social media. This research aims to find out the information behavior of Indonesian faculty members on social media, especially on Facebook, Telegram, and WhatsApp. The focus of this research is in-depth understanding of the needs, search, organization, and use of information by Indonesian faculty members on social media. This research is qualitative research using a virtual ethnographic approach. The research data was obtained through participatory observation, in-depth interviews, and a literature review. The selection of informants was done by purposive sampling, while triangulation was done by data sources and theories triangulation. The results showed that the information behavior of Indonesian faculty members on social media began with the need for information, choosing social media, choosing and entering into one or several groups, sharing information, and discussing in a group. Some faculty members keep the information, and some choose to ask when they need the information, even though the information has been discussed. The information obtained is used when they need it, and they usually share their experiences with other group members.

Purpose: The purpose of this study was to investigate factors influencing lifetime smoking and current smoking among adolescents in South Korea. Methods: Hierarchical logistic regression was conducted based on complex sample analysis using statistics from the 10th (2014) Korea Youth Risk Behavior Web-Based Survey. The study sample comprised 72,060 adolescents aged 12 to 18. Results: The significant factors influencing adolescent lifetime smoking were female gender, older age, higher stress, higher weekly allowance, lower economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. The significant factors influencing adolescent current smoking were female gender, older age, higher stress, higher weekly allowance, both higher and lower economic status compared to middle economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. Conclusion: Factors identified in this study need to be considered in programs directed at prevention of adolescent smoking and smoking cessation programs, as well as policies.

The objective of this study is to quantitatively incorporate user observation into usability evaluation of mobile interfaces using monitoring techniques in first- and third-person points of view. In this study, an experiment was conducted to monitor and record users' behavior using Ergoneers Dikablis, a gaze tracking device. The experiment was done with 2 mobile phones each with a button keypad interface and a touchscreen interface for comparative analysis. The subjects included 20 people who have similar experiences and proficiency in using mobile devices. Data from video recordings were coded with Noldus Observer XT to find usage patterns and to gather quantitative data for analysis in terms of effectiveness, efficiency and satisfaction. Results showed that the button keypad interface was generally better than the touchcreen interface. The movements of the fingers and gaze were much simpler when performing given tasks on the button keypad interface. While previous studies have mostly evaluated usability with performance measures by only looking at task results, this study can be expected to contribute by suggesting a method in which the behavioral patterns of interaction is evaluated.

We report the experimental finding that there exists a transition of magnetization reversal process with varying the applied field in Co/Pd multilayer. We have measured the wall-motion speed V and the nucleation rate R during magnetization reversal via time-resolved direct domain observation, where the magnetization reversal process of Co/Pd multilayer is found to take a transition from thermal activation process to viscous process at the critical field of about 1.87 H$\_$C/ (coercivity). In the thermal activation regime, we find that the field dependences of two activation volumes for the wall-motion process and the nucleation process are different with each other, which reveals that the wall-motion and nucleation experience completely different interactions. In the viscous regime, we find that the wall-mobility is much smaller than a typical value for the sandwiched Co films, which implies that the Co/Pd interfaces in multilayer substantially contribute to the dynamic dissipation.

The purpose of this study was to identify fashion leadership and information seeking as a part of adolescents'clothing purchase behavior study. The questionnaire was administered to 291 junior high school students. The data were analyzed using factor analysis, t-test and ANOVA utilizing SPSS/PC/sup +/. The results of this study were as follows: 1. The adolescents usually used store information seeking and consultation with friends as continuous information seeking. The adolescents usually read fashion articles in the fashion magazine more than fashion advertisements. As information seeking before purchasing, they watched store displayed or window displayed clothes the most, and then consulted with friends or family members. The degree of information seeking before purchasing was significantly different according to the number of purchasing clothes. 2. Three factors (mass communication informations, observation & personal information, and family members information) of information sources derived by factor analysis. 3. Three groups were classified as fashion leaders, fashion flowers, and fashion laggards according to fashion leadership. Girls perceived themselves as fashion leaders much more than boys did. There was significant difference among three fashion leadership groups in the number of purchasing clothes and price partially. 4. Fashion leaders seeked the continuous information and mostly used mass communication information sources and observation & personal information as information sources before purchasing clothes.

최근까지 국내에서는 팽이기초에 관한 연구가 미흡하였고, 지반조건에 맞는 설계기준이 마련되어 있지 못하여 일본의 설계기준을 그대로 사용하고 있는 실정이다. 이로 인해 기존 팽이기초의 지지력식은 과소하게 예측되는 문제점이 있다. 따라서 본 연구에서는 실제크기의 1/5 스케일로 축소한 모형실험을 수행하였으며, 국내에서 이루어 진 100여개 현장의 재하실험 결과를 근거로 강도특성(N값), 지하수영향, 팽이기초의 파괴형상을 고려하여 보다 합리적으로 팽이기초의 지지력을 예측할 수 있는 식을 제안하였다.

Southern Great Plain 1999 실험을 통하여 획득된 L-band와 C-band 토양수분 측정치의 공간 변화 양상을 분석하였다. L-band 토양수분 측정치의 스펙트럼은 관측 스케일의 변화와 함께 토양수분의 공간 변화 양상이 변화됨을 보여주었고, 이러한 변화 양상은 모래함유비와 같은 토양 특성의 공간 변화 양상과 일치함을 보여주었다. 그리고 C-band 토양수분 측정치의 공간 변화 양상은 관측 스케일의 변화와 상관없이 일정한 변화도를 가지는 것으로 나타났다. 이는 식생피복의 공간 변화 양상과 동일함을 보여주는 것이다. 이러한 결과는 AMSR기기를 이용하여 현재 진행되고 있는 토양수분의 전 지구 관측치의 downscaling시 고려되어야 할 것이다.
