This study was examined the effective nonverbal behavior cues of detecting suspects' lies in the investigation scene. In order to search the suspects who drank the alcohol liquor without a permission, 18 soldiers were interviewed. 8 solders had drunken alcohol and had lied when was asked(lie group). The other 10 soldiers hadn't drunken alcohol and had told the truth(truth group). The mean frequencies of nonverbal behaviors were compared lie group with truth group. The following behaviors were measured by frequency: vocal characteristics (high pitch of voice, speech hesitations, speech error, frequency of pauses, period of pauses, latency period), facial characteristics (gaze, smile, touching face, blinking, facial micro-expression), body movement (illustrators, hand and finger movement, leg and foot movement, head movement, trunk movement, shifting position). As results, this study found that deception cues were periods and frequencies of pause, micro-expression, head movements. The lie group had less periods and frequencies of pause, and more micro-expression, head movements than truth group. But, this study didn't found Othello's error cues.

The perceived stress response inventory(PSRI) was developed to measure 4 types of current stress responses : emotional, somatic, cognitive, and behavioral responses. 242 patients with psychiatric disorders(71 patients with anxiety disorders, 73 patients with depressive disorders, 47 patients with somatoform disorders, 51 patients with psychosomatic disorders) and 215 healthy subjects completed the questionnaire including the PSRI. Global assessment of recent stress(GARS) scale, perceived stress questionnaire(PSQ) and symptom checklist-90-revised(SCL-90-R) were also administered at the same time. Factor analysis for each of 4 types of stress responses yielded 8 factors : negative emotional responses, general somatic symptoms, specific somatic symptoms, lowered cognitive function and general negative thinking, self-depreciative thinking, impulsive-aggressive thinking, passive-responsive and careless behavior, and impulsive-aggressive behavior. Both test-restest reliability(r= .83 -.93) and internal consistency(Cronbach's alpha : .79 -.96 for each of 8 subscales and .98 for total items of the scale) were all at statistically significant levels. Total scores of the PSRI significantly correlated with total scores of GARS scale, PSQ, and global indicies of SCL-90-R, respectively. The patient group had significantly higher scores than healthy subjects in each of all the subscales except impulsive-aggressive behavior subscale. These results suggest that the PSRI is a reliable and valid tool stable over time which may be effectively used for the research in stress-related field including psychosomatic medicine.

The purpose of this study was to investigate the effects of Adapted Physical Education Majors' perceived teacher competencies on the emotion reaction towards challenging behaviors of students with disabilities. In order to achieve the object of the study, the data collected from 413 sophomores, juniors, and seniors currently studying adapted physical education in schools located in Seoul, Gyeonggi, Gyeongnam, and Gyeongbuk, where they offer department of adapted physical education, was analyzed. As a measuring tool, Kwon (2008) and Han (2011) questionnaire for adapted physical education educators' perceived teacher competency and Oh, Seo & Kozub's (2010) questionnaire on the emotion reaction towards challenging behaviors of students with disabilities were revised, modified, and reconstructed. Data was processed using SPSS 21.0, and the exploratory factor analysis, reliability verification, difference verification, and multiple regression analysis were performed. The results are as follows. First, in terms of the analysis of emotion reaction based on demographic characteristics (sex, grade, disability in the family, friends with disabilities), sex, grade, and friends with disabilities displayed statistically significant difference on emotion reactions. Second, in terms of the effects of adapted physical education educators' perceived teacher competencies on the emotion reactions on towards challenging behaviors of students with disabilities, the parental education and the special activities of adapted physical education among the sub-factors of perceived teacher competencies affected significantly on emotion reactions, whereas the common knowledge on adapted physical education, curriculum lesson, and education knowledge by disability did not affect significantly on emotion reactions.

기존의 로봇은 주로 예측 가능한 환경 하에서 동작해왔다. 그러나 로봇의 적용분야가 확대되면서 예측하기 힘든 복잡한 자극에 대해 반응하도록 요구되고 있다. 복잡한 자극은 동일시간에 여러 가지 자극이 존재하는 공간적 복잡성과, 각기 다른 시간에 자극이 연속적으로 배열된 시간적 복잡성을 가진다. 기존의 로봇은 복잡한 자극에 대한 대처능력이 취약하다. 이러한 환경에서 적응할 수 있도록 여러 방면의 연구가 진행되어 왔으며, 그 중에서 동물이 환경의 변화에 대처하는 방법에 관한 많은 연구들이 진행되고 있다. 본 논문에서는 시간적 복잡성을 가진 자극에 반응하고 이를 학습하기 위해 HMM(Hidden Markov Model)을 이용한 시계열 학습구조를 제안한다. 또한 기본적인 행동선택 및 학습을 위해 동물의 행동선택을 모델링한 구조를 구현하였다.

In this paper, we investigated the effects of response technique which uses free tokens in the computer training for the mentally retarded person. We set wrong line entering. wrong space number entering, wrong line-type designation and wrong cell merger as the target behaviors in the research. The experiment period of the research was 36 sessions altogether, and the period was divided into four steps such as basic period I. treatment period I, basic period II, and treatment period II. We also conducted a follow up experiment to identify whether the experiment's effect is still maintained two weeks after the experiment finished. We know that the response cost technique which uses free tokens to the mentally retarded person is efficient in the computer training.

베이지안 네트워크는 변수들간의 원인-결과 관계를 확률적으로 모델링하기 위한 도구로서 소프트웨어 사용자의 목적을 추론하기 위해 널리 이용된다. 행동기반 로봇 설계는 반응적(reactive) 행동 모듈을 효과적으로 결합하여 복잡한 행동을 생성하기 위한 접근 방법이다. 행동의 결합은 로봇의 목표, 외부환경, 행동들 사이의 관계를 종합적으로 고려하여 동적으로 이루어진다. 그러나 현재의 결합 모델은 사전에 설계자에 의해 구조가 결정되는 고정적인 형태이기 때문에 환경의 변화에 맞게 목표를 변화시키지 못한다. 본 연구에서는 베이지안 네트워크를 이용하여 현재 상황에 가장 적합한 로봇의 목표를 설정하여 유연한 행동선택을 유도한다. Khepera 이동로봇 시뮬레이터를 이용하여 실험을 수행해 본 결과 베이지안 네트워크를 적용한 모델이 상황에 적합하게 목적을 선택하여 문제를 해결하는 것을 알 수 있었다.

The purpose of this study was to examine whether there was a difference in the recognition and teaching strategies for the young child's behavioral problems according to teachers' socio-demographic variables and ego-resiliency level by analyzing survey responses from 238 teachers of 3, 4, and 5-year-old children. This study found that the group of teachers with the education level of junior college graduation or higher showed higher degree of recognition of children's behavioral problems than the group of teachers with a lower level of education. And the group of teachers at kindergartens showed a higher degree of recognition of children's behavioral problems than the group of teachers at day care centers. Regarding the difference according to the level of ego-resiliency, the group of higher ego-resiliency showed higher degree of recognition of children's behavioral problems than the group of lower ego-resiliency. In terms of teachers' teaching strategies for the behavioral problems, differences were recognized at sub-categories. To explain, differences were recognized in accordance with the teachers' age and career as well as their education level and work place; the higher the teachers' age, career, and education the more often they used the positive prevention strategy I. And teachers at kindergartens resorted to the negative response strategies more often than those at day care centers. Finally, the teaching strategies for the behavioral problems according to the teachers' ego-resiliency, group differences were seen in all the sub categories. The result of this study suggested that the need to develop and apply such programs for pre-service teachers and for teacher reeducation reflect those variables.

In this paper, we investigate intellectual reaction differences among market participants to various corporate information announcements and the main information prompting investors to trade. Our research is based on IPO companies listed on the KOSDAQ exchange from January 2000 to September 2012 and concentrates on three information disclosures - bonus issue, seasoned equity offer, and new investment in facilities announcements. We find that intellectual market participants react positively to bonus issues and seasoned equity offers, but negatively to new investment announcements. Market trading volume increases before the positive events and all cgroups actively buy shares during these periods. For the negative events, only institution participants show active selling. Overall, institutions act as momentum traders, and individuals and foreigners as contrarian traders. We also discuss the implications of this study.
