The objective of this study is to investigate the effect of building integrated PV application method on power generation. PV modules were integrated to a hypothetical apartment building facade in Seoul, Korea. Three different design options of PV panel mounted on exterior wall were developed for the analysis of cooling effects through ventilation. Numerical simulations using TRNSYS coupled with COMIS were executed to evaluate the design options. Their facade configurations are such as vertically installed PV panels with or without air gap between PV rear surface and exterior wall surface, and the tilted PV panels attached to the exterior wall at an angle of to the horizontal. Parametric results show that there is little difference regardless of the air gap width between PV rear surface and exterior wall surface. Special strategies which could effectively cool a PV panel to increase the electric power are required if we prefer to a vertical facade configuration in a building integrated PV installation. Consequently, it is expected that there is no reason for architect to install vertically PV panels with air gap unless active strategies are considered.

이 연구는 ADHD 시설아동의 자기통제와 자아존중감에 집단미술치료가 미치는 영향을 살펴보기 위한 목적으로 진행하였다. 연구대상은 초등학교 4~5학년에 재학 중인 시설아동으로 그들의 환경적 특성에 따라 우울감과 고립감 및 패배감 등에 의한 낮은 자아존중감과 ADHD로 인한 자기통제의 부적절함을 가지고 있다고 보고된 아동들이다. ADHD로 진단된 아동들 중 집단미술치료에 관심을 보인 아동 6명을 실험집단으로 구성하였으며 그렇지 않은 6명을 통제집단으로 구성하였다. 실험집단은 한 회기당 60분씩 주 1회로 총 20회기 동안 집단미술치료를 실시하였다. 연구의 결과는 첫째 집단미술치료는 ADHD 시설아동의 자기통제력에 긍정적인 효과가 있는 것으로 나타났다. 둘째 집단미술치료는 ADHD 시설아동의 자아존중감 향상에 효과가 있는 것으로 나타났다. 따라서 자기통제와 자아존중감 변화에 초점을 두고 구성된 집단미술치료는 내면적인 심리적 변화와 각성을 유도하여 스스로의 가치를 인식하고 자기를 조절하는 역할을 하는데 효과가 있다고 판단된다. The purpose of this study was to investigate the effect of group art therapy on self-control and self-esteem of institutionalized children with ADHD. For the study institutionalized children in 4th and 5th grade were selected who were reported to have low self-esteem by the sense of depression isolation and defeat according to their environmental characteristics and show inadequate self-control according to ADHD. Among children with ADHD 6 children who took interest in group art therapy for the experimental group were selected and 6 other children for the control group were selected. The results of the study were as follows: First group art therapy had a positive effect on self-control of institutionalized children with ADHD. Second it had an effect on improved self-esteem of the children. Accordingly it is judged that such group art therapy concentrating on changes in self-control and self-esteem works for self-value recognition and self-control by stimulated psychological changes and realization.

Objectives : Trauma patients have attentional bias which enforces traumatic memories and causes cognitive errors. Understanding of such selective attention may explain many aspects of the posttraumatic stress disorder(PTSD) symptoms. Methods : We used the rapid serial visual presentation(RSVP) method to verify attentional blink in burn patients with PTSD. International affective picture system(IAPS) was used as stimuli and distracters. In the 'neutral test', patients have been presented series of pictures with human face picture as target stimuli. Each picture had 100ms interval. However the distance between target facial pictures was randomized and recognition of second facial picture accuracy was measured. In the 'stress test', the first target was stress picture which arouses patient emotions instead of the facial picture. Neutral and Stress tests were done with seven PTSD patients and 20 controls. In '85ms test' the interval was reduced to 85ms. The accuracy of recognition of second target facial picture was rated in all three tests. Eighty-five ms study was done with eighteen PTSD patients. Results : Attentional blinks were observed in 100-400ms of RSVP. PTSD patients showed increased recognition rate in the 'stress test' compared with the 'neutral test'. When presentation interval was decreased to 85 ms, PTSD patient showed decrease of attentional blink effect when target facial picture interval was 170ms. Conclusion : We found attentional blink effect could be affected by stress stimulus in burn patients. And attentional blink may be affected by stimulus interval and the character of stimulus. There may be some other specific mechanism related with selective attention in attentional blink especially with facial picture processing.
