Objectives : Illness behavior is defined as the persistence of an adaptive/maladaptive mode of perceiving, evaluating and responding to health status and symptoms according to the status. In a cognitive aspect, somatizing symptoms are regarded as being originated from distortions, including magnification and/or amplification, of perceiving, evaluating and responding to symptoms such as bodily sensations. That is somatization may be explained by maladaptive illness behavior. In this study, we tried to investigate differences of illness behavior in depressive patient according to the presence of somatization. Methods : We divided 45 patients who were diagnosed as depression with ICD-10 diagnostic criteria into two groups(somatizing and non-somatizing group) according to the somatization subscale of Korean Depression Scale and compared two groups in the differences of illness behavior using the Illness Behavior Questionnaire. Results : Somatizing group showed significantly higher scores than non-somatizing group on the disease affirmation subscale($6.79{\pm}2.08$ vs. 4.76, p=0.003) and the denial subscale($3.25{\pm}1.22$ vs. $2.10{\pm}1.41$, p=0.006). There were no significant differences between two groups on the general hypochondriasis subscale and the affective unstability subscale. In a logistic regression analysis, somatizing group also showed higher odds ratio (OR) scores on the disease affirmation subscale(OR=1.418, p=0.089) and the denial subscale(OR=1.880, p=0.083). Conclusion : The disease affirmation and denial may be a discriminative mechanism of somatization in depressive patients. These subscales of Illness Behavior Questionnare could be useful markers, and psychiatric illnesses with somatizing and depressive symptoms may be differentially diagnosed and be predicted through these subscales.

Human arousal represents one of human emotion dimension. Its effort on human performance has been generally accepted at a invert-cup trend. h optimal range of human arousal enhances human performance However, definition of arousal is not Vet clear. Human arousal has different types depending on the causes. This paper observes different reponses based on different arousals such as cognitive arousal and physical arousal. Twenty undergraduate students participated and experienced cognitive and physical arousals. Their physiological response were analyzed and differentiated between cognitive and physical arousal. Finally, significant difference between them are not shown in autonomic responses but in central nervous responses.

Pain is subjective and greatly influenced by prior experiences, but it is real. Pain associated with an organic(objective) pathology is more easily explained and treated. However, atypical or unexplainable pain is usually a source of greater confusion and frustration. Pain may be divided into four general diagnostic categories. 1) pain with anatomic features and objective findings 2) pain with anatomic features and without objective findings 3) pain with non-anatomic features associated with stress and somatization 4) pain with non-anatomic features associated with perceived physical injury. There is a well-established relationship between emotional, physical and/or sexual abuse history and development of chronic pain. It has been suggested that the link between somatization and abuse involves a paradoxical pattern of hiding feelings and reality, while seeking acknowledgment of suffering. History of abuse may physiologically and developmentally increase a person's susceptability to pain and organic changes can be associated with psychogenic disease. Patients with chronic pain should be treated with multidisciplinary approaches including exercise, meditation, cognitive therapy, medications, and biofeedback. Cognitive therapy alters patient's cognition and management of pain and alleviates pain, especially associated with stress. Antidepressants are the most commonly used medications and pain control effects have no relation with mood changes. Biofeedback with relaxation training, exercise and meditation may also be effective in pain control.

The purpose of this study was to investigate the relationships between cognitive function and self efficacy, health behavior of the elderly participation to physical activity. Data were collected from November 2015 to January 2016. The study subjects were 61, aged 65 years or older, to visit health town. The questionnaire was composed general characteristics and K-MoCA, self-efficacy scale, self-efficacy for exercise tools, Korea's elderly health behavior. The results of the study were as follows: As for cognitive function and exercise self-efficacy by general characteristics, there were differences in that regard according to gender, education, marital status, dependents form, duration of the program(p <.05), the general self-efficacy showed differences in gender, age, education, economic status, duration of the program(p <.05), and the health behavior showed differences in gender, education, marital status, dependents form, activity program, duration of the program(p <.05). There was a significant correlation between cognitive function and exercise self-efficacy, health behavior(p <.01). General self-efficacy was correlated with exercise self-efficacy, health behavior. And exercise self-efficacy was correlated with health behavior(p <.01). Exercise self-efficacy were the factor affecting the cognitive function(p <.01). Therefore, the activity program development for the practice and sustainable participation in physical activity in the elderly is believed to be made.

Korea has recently entered a rapidly aging society. The problem of the elderly due to the aging society appears in various fields. Problems caused by cognitive deterioration as well as problems caused by physical weakness also cause many problems. Cognitive deterioration causes difficulties in the daily life of the elderly, which negatively affects the quality of life of the elderly. The purpose of this study is to conduct a user analysis for the development of financial education systems which can facilitate daily life activities of cognitively deprived elderly. Through this study, we develop representative elderly cases in which cognitive decline can occur and lay the foundations for the development of financial education contents based on them.

최근 통신 기술의 발달로 온라인을 통한 대규모 콘텐츠의 유통이 가능해졌으나, 사용자들은 수많은 콘텐츠 사이에서 원하는 정보를 찾는 시간이 단축되는 것을 원했다. 이로 인해 다양한 분야에서 개인화된 콘텐츠를 추천해주는 추천 시스템(recommendation system)에 대한 요구가 점차 높아졌다. 그럼에도 불구하고 시니어를 위한 추천 시스템에 대한 연구는 매우 부족하다. 또한, 시니어 세대의 변화에 따라 시니어 관련 콘텐츠 연구도 다양하게 진행되고 있으나, 스마트 기기 및 서비스가 젊은 층에 친화적으로 개발됨으로써 시니어 층의 접근성을 감소시키고 있다. 이에 본 연구에서는 다양한 신체적 변화를 겪는 시니어 세대 위해 추천 시스템에서 인지반응 데이터를 이용하여 콘텐츠를 시청하기 적합한 환경을 제공함과 동시에 활동 이력을 중심으로 개인화 추천 시스템을 설계하여 시니어 사용자들의 개념 변화(concept drift) 문제로 사용자가 원하지 않는 콘텐츠를 추천받을 가능성을 줄일 수 있도록 한다.

When simulating large crowds, it is inevitable that the models and motions of many characters will be cloned. McDonnell et al. analyzed user's perception to find cloned characters. They established that clones of appearance are far easier to detect than motion clones. In this paper, we expand McDonnell's research[1], with the focus on multiple clones and the appearance variety in real-time game environment. Introducing the perceptual organization, we show the appearance variety of crowd clones by using game items and texture modulation. Other factors that influence the ability to detect clones were examined, such as the moving direction and distance between character clones. Our results provide novel insights and useful thresholds that will assist in creating more realistic crowds of game environments.

This study aims to present the effects that a bibliotherapy program based on picture books and paper craft art activities had on middle school students' stress recognition and the changes in their reactions. To this end, we adopted an experimental research design model with pre/post-test measurements of stress recognition and reactions using first grade middle school students with emotional difficulties. The results show that a bibliotherapy program based on picture books and paper craft art activities does have significant effects on the stress recognition and reactions of middle school students. The 5 of 5 sub-domains of the stress recognition had significant difference. The sub-domains are: family environment, friends, study, teacher/school. The 6 of 7 sub-domains of the stress reactions except fatigue had significant difference. The sub-domains are: tention, frustration, anger, depression, somatization, aggression.
