Objectives : It has been reported that caregivers of patients with chronic mental illness including schizophrenia are in higher risk for psychological and physical health problem. This study was performed to evaluate the depressive symptoms and associated factors in caregivers of patients with chronic mental illness. Methods : The subjects were 77 unaffected caregivers (30 parents, 30 siblings, 10 offspring, and 7 spouses) of patients with chronic mental illness (62 schizophrenia, 4 schizoaffective disorder, 11 bipolar disorder) and 100 healthy controls. Depressed mood was assessed by Beck Depression Inventory (BDI) in all subjects. For their sick family members, clinical factors including psychotic symptoms using the Positive and Negative Syndrome Scale (PANSS), duration of illness, number of admission were assessed. Results : The mean BDI score of the caregivers was significantly higher than that of control subjects (11.2±11.6 and 8.0±17.5). Given that 23.4% of family group and 23.0% of control group are attributed to mild to moderate depressed state and 22.0% of family group and 8.0% of control group to above moderate depressed state, significant depressive symptom is more frequently observed in family group. The mean BDI score of parent group was higher than that of sibling group controlling for sex and age. In the parent group, BDI scores are positively correlated with age while the offspring and spouse group had negative correlation between BDI scores and age. Higher age, lower socioeconomic state, more severe positive symptom scores of patients were potential predictors for BDI scores of caregivers. Conclusion : This study showed that caregivers of patients with chronic mental illness have significant depressive symptoms. It may be suggested that depressive symptoms of caregivers are associated with aging, low socioeconomic state, and severe positive symptom rather than chronicity of their sick family members.

( Park Seong Man ),( Cha Minyoung ) 한국현대영어영문학회 2016 현대영어영문학 Vol.60 No.4

This study focuses on comparisons among worship related services and focuses on Korean immigrant church members` perceptions toward diverse divine services and toward youth members` Korean language and cultural identity maintenance within the Korean immigrant church. The aim of this study is to suggest the possible ways for Korean immigrant youth to maintain Korean ethnic identity and ethnic language. This study was conducted in a Korean immigrant church located in Montreal, Canada by the use of interviews, a questionnaire, and participant observation over 7-week period. The participants (n=23) were Korean immigrant adult members (n=10) and Korean immigrant student members (n=13). The results of the study reveal that the Korean language provide multicultural awareness and ethnic unity among the Korean diaspora population, more specifically in the Korean immigrant church context, within the multicultural context. Overall, the results of the study show that most of the participants have positive attitudes toward the Korean language divine service, and they prefer the Korean language divine service to the simultaneous interpretation service and the English language divine service within the Korean immigrant church.

인스턴트 메신저 기반 통신에서 사용자의 감정을 자동으로 인식하고 이를 개인화된 3D 캐릭터 애니메이션으로 표현한다면 기기를 통한 통신에 더 많은 감성을 부여할 수 있고 궁극적으로 의사소통의 효과를 제고할 수 있다. 본 논문은 IPTV (Internet Protocol Television) 환경에서 자동화된 감정 인식 및 표현을 위해 개발된 감성 메신저 시스템에 대해 기술한다. 효율적인 사용자 감정 전달을 위해 텍스트 기반 감정 추측, 3D 렌더링 및 동영상 재생 방식을 동시 지원하는 캐릭터 애니메이션, 스마트폰을 통한 메시지 입력등을 제안한다. 개발된 감성 메신저의 효과와 성능은 시연 및 실험을 통해 검증하였다. In the environment of instant messengers, the recognition of human emotions and its automated representation with personalized 3D character animations facilitate the use of affectivity in the machine-based communication, which will contribute to enhanced communication. This paper describes an emotional messenger system developed for the automated recognition and expression of emotions for IPTVs (Internet Protocol televisions). Aiming for efficient delivery of users' emotions, we propose emotion estimation that assesses the affective contents of given textual messages, character animation that supports both 3D rendering and video playback, and smart phone-based input method. Demonstration and experiments validate the usefulness and performance of the proposed system.

박성만(Seong Man Park),차민영(Minyoung Cha) 한국영어어문교육학회 2016 영어어문교육 Vol.22 No.2

This paper explores the Korean ethnic church members’ attitudes toward the English translation service of the Sunday worship service for Korean immigrant youth in Montreal. This study also investigates the relationship between the adoption of the translation service and the Korean language and culture maintenance. The study involved qualitative interviews, a questionnaire, on-site document analysis, and participant observation. The participants (n=21 in total) were Korean immigrant students between the ages of 13 and 19, who attend a Korean ethnic church in Montreal (n=8), Korean immigrant adult church members (n=10), pastors of the church (n=2), and a translator of the service (n=1). This study confirms Korean ethnic church members’ positive attitudes towards the English translation service for keeping the Korean immigrant youth within the church. In addition, the study shows that the adoption of the translation service helps the Korean immigrant youth maintain the Korean language and cultural identity. Thus, this study suggests that the translation service should be a strategic choice for Korean ethnic churches to keep Korean immigrant youth without the sacrifice of the Korean language as their heritage language. Some implications for immigrant youth’s Korean language maintenance as a heritage language in Canada are briefly touched on.

The current study had the radiation workers working in nuclear medicine department wear individual exposure dosimeters in the front and in the back, considering the underestimated individual exposure to radiation from patients undergoing radiological medicine treatment. The utility of the device was assessed in the study. From January 2015 to February 2015, 85 radiation workers working in 11 Korean nuclear medicine department were analyzed by their workplace and their specialty; PET-CT and gamma cameras were used to analyze the radiation exposure in the front and the back of the radiation workers. This revealed that the exposure measurement and assessment using the dosimeter worn on the front were not underestimated. However, because this measurement did not take into account the adequate radiation weighting factor for the back side dosimeter, a radiation exposure assessment algorithm for the back side radiation exposure must be developed, which can be used as a basic data for introducing double dosimeter for radiation workers working in nuclear medicine department.

The purpose of this paper is to examine the learners` academic achievement and class satisfaction on doing flipped learning in English reading and writing class. Flipped learning is a kind of blended learning which reverses the traditional learning model. In this study, students are required to study online instruction in advance which is offered by their instructor before they study in the classroom. Online contents mostly consist of vocabulary and grammar, and offline classes were progressed with students` activities, tasks or discussions. The subjects were 57 college students in English reading and writing courses. The results are as follows. More than 70% of the students positively responded on the effectiveness, convenience, time ratio, interest and concentration level, and preference categories in the satisfaction survey. The self-directed learning ability was slightly improved but it wasn`t significantly different from the controlled class. The students` academic achievement was significantly improved in this study, but it didn`t show a significant difference from the controlled class. Based on these findings, pedagogical implications for the contents of the flipped class are suggested. (Dankook University)

With an increase in the commercialization of electricity, and the development of advanced and large electric devices and various wireless radio wave services, concerns over the effects of electromagnetic fields on human health have increased. Accordingly, the World Health Organization encouraged the development of international standards by establishing the 'International Electromagnetic Fields Project' in 1996 based on studies on the harmful effects of electromagnetic fields on the human body. Moreover, the National Institute of Environmental Health Sciences (NIEHS) classified electromagnetic fields as possible carcinogens under Group 2B category, even though they have been found to have a weak correlation with those effects on human health. Mid-to-large-sized electric facilities used at industrial sites mostly adopt a commercial frequency of 60 Hz, and workers handling these facilities are exposed to such extremely low frequency (ELF) fields for a long time. A previous study suggested that exposure to ELF electromagnetic fields with frequency ranges from 0 to 300 Hz, even for a short time, at densities higher than 100 μT may have harmful effects on human body as it affects the activation of nerve cells in the central nervous system by inducing an electric field and current and stimulating muscles and the nervous system in the body. Such studies, however, focused on home appliances used by ordinary people, and research on facilities utilizing high-capacity current and operated by workers at industrial sites is lacking. Therefore, in this study, a 3000 kilowatt generator, which is a high-capacity electric facility employed at industrial sites, was investigated, and the size of the magnetic fields generated during its no-load and high-load operations per distance to produce a map was measured to reveal spots deemed hazardous according to domestic and international exposure standards. The findings of this study is expected to alleviate workers' anxiety about the harmful effects of magnetic fields on their body and to minimize the level of exposure during operations.
