In this study, Exit light installed in offices, malls, hospitals, and factories were analyzed to analyze the luminance performance of CCFL and LED light sources. In addition, fire protection products with electrical characteristics such as Exit light may change their performance due to ambient temperature, humidity, and dust. So it was extracted by installation place and analyzed its characteristics. As a result of the experiment, Exit light for CCFL type showed the value of 'ratio of luminance 2' for large, medium and small. Considering that the reference value was 'lower than 9', the value was very good and it can be seen that there is almost no change in ratio of luminance due to aging. The Exit light for LED type showed a value of 'ratio of luminance 5', which means that the light on the display surface is not uniform. In addition, there was almost no change in ratio of luminance due to ageing, but the ratio of luminance was larger than Exit light for LED type. This is an unsatisfactory result from a visual point of view. To improve this, it is necessary to disperse the light of LED light source and strengthen the regulation on ratio of luminance.

사람의 흡충류감염(吸蟲類感染)은 대부분(大部分) 열대(熟帶) 및 동부아세아지역(東部亞細亞地域) 여러 국가(國家)에서 발생(發生)한다. 주혈흡충증(住血吸蟲症), 간흡충증(肝吸蟲症), 태국간흡충증(泰國肝吸蟲症), 간흡충증(肝吸蟲症), 요꼬가와흡충증(吸蟲症), 이형이형흡충증(異型異型吸蟲症) 및 폐대흡충증(肺大吸蟲症)등은 어떤 일부(一部) 아세아국가(亞細亞國家)에 있어서 공중보건상(公衆保健上) 중요(重要)한 문제(間題)가 되어 있다. 이와 같은 패류매개성기생충감염(貝類媒介性寄生蟲感染)은 풍토병(風土病)을 일으키고 있다. 사람들의 생활습관은 풍토병을 일으키게될 원인이 될 뿐만 아니라 때로는 그 질병(疾病)을 유행(流行) 전파(傳播)시키는 기본적 요소가 되기도 한다. 주혈흡충을 제외한 흡충류감염은 우리가 중간숙주(中間宿主)을 먹었을때 그곳에 있었던 피낭유충(被囊幼蟲)에 의하여 감염이 이루어 진다. 식물(植物)의 생식(生殖)(간질(肝蛭), 폐대흡충(肺大吸蟲)), 게 및 가재 생식(폐흡충), 민물고기 생식(간흡충, 요꼬가와흡충, 이형이형흡충), 또는 우렁이 생식(극구흡충(棘口吸蟲)), 기타(몇가지 우연적감염(偶然的感染))등은 사람의 흡충류감염의 주 원인이 되는 것이다. 한편 주혈흡충 감염은 요염수원(汚染水源)에 접촉한 피부을 뚫고 들어온 쎌카리아 유충(幼蟲)에 노출되기 때문에 일어난다. 흡충류감염에 대하여 예방과 방어에 관한 공중보건학적 조치는 많다. 이들의 조치중에는 화학요법에 의한 감염원을 감소시키는 것, 패류숙주의 박멸, 만족할만한 위생시설의 비치, 급수시설, 보건교육, 진단기술의 보급, 환경관리 및 개선 등이 포함된다. 그러나 감염자들에 대한 화학요법은 가장 빠르고 효과적인 억제방법인 것으로 나타나고 있다. 흡충류감염을 예방하는데 있어서 가장 중요한 변화는 프라지콴텔과 같은 신약의 개발이었다. 프라지콴텔은 모든 종류의 주혈흡충, 간흡충, 폐흡충 및 여러가지 장내기생 흡충류등 사람의 병원성흡충류에 대한 치료제로서 가장 좋은 특효약이다. 흡충류감염이 중요한 보건문제가 되어 있는 곳에서는 그 예방과 억제책에 있어서 장단기계획(長短期計劃)을 수립하는 것이 좋을 것 같다. 단기는 집단화학요법을 조기에 실시하여야 하고 자기는 "비특이성 기구"로써, 예를들면 위생시설 및 급수시설의 설치, 보건교육등으로 감염을 감소시켜 감염유지 수준이하로 보지(保持)시키는 것이다. 이와같은 억제조치를 착실히 수행하기 위하여 많은일이 있다. 예를 들면 집단참여, 역학적 조사, 약물의 공급, 환경관리, 보건교육, 지역사회관련, 일차보건 진료와의 협조 및 재정후원등에 대하여 검토하고 연구하여야 할 것이다.

Purpose: This study was to determine the effect of a smartphone video educational program on educational satisfaction of patients in rehabilitation units at a university hospital. Methods: The subjects of this study were 60 stroke patients recruited and divided into two groups; experimental group (n=30) and control group (n=30). Subjects in the experimental group and control group conducted conventional physical and occupational therapy. In addition, only the experimental group provided smartphone video information for a total of 15 sessions. The video consisted of five episodes (10 minutes each) viewed a total of 15 times (for each video three times). The outcome was assessed by educational satisfaction. Result: After inervention, both groups revealed significant increased awareness of prevention of infection educational satisfaction and prevention from falling educational satisfaction and exercise program educational satisfaction. However, the experimental group was more effective than the control group relative to heightened awareness of increasing prevention of infection prevention from falling and exercise program. Conclusion: We suggest that a smartphone video educational program may be effective in improving awareness of the prevention of infection, prevention from falling, and exercise program educational satisfaction. Therefore, video-based information is beneficial for such patients. Further studies are needed for better understanding of the effectiveness of a smartphone video educational program in rehabilitation units at a university hospital.

The study, was conducted to become conscious of the impact of emotional labour on dental hygienists' self-esteem with job stress. Participants were 205 dental hygienist's in the dental clinic. Data were gathered from Jan 3 to Jan 30, 2016, using structured questionnaires. The analysis shows that there was a negative correlation with self-esteem in emotional labour, however, positive correlation was presented in employment stress. It also appears to have no relationship between self-esteem and job stress. Therefore, emotional labour has a direct effect on increasing job stress and lowers self-esteem. The lowered self-esteem simultaneously has an indirect effect on increasing job stress. The measures to counter the problems of emotional labour of dental hygienist and education considering dental hygenist's self-esteem should be accomplished place to maintain the level of emotional labour and the clinic's determination to rectify the issues are essential.

The organizational effectiveness of hospital in various environmental fluctuations is a large and complex problem. Hospital CEO leadership characteristics may be a critical determinant of employees' job satisfaction and turnover intention. Several empirical studies on transformational leadership found that transformational leadership behaviors were positively related to workers' job satisfaction and turnover intention. Very little research related to this subject has been done in health care settings in Korea. The author explores the relationship between hospital CEO leadership style and its effect on job satisfaction and turnover intention among the all staffs of general hospital. The relationship of hospital CEO leadership style to employees' job satisfaction was investigated using the Bass's leadership paradigm of transformational and transactional leadership. The Multifactor Leadership Questionnaire(MLQ) and the index of job satisfaction and turnover intention were completed by 493 hospital employees(doctors, nurses, hospital administrators, technicians, and assistants). The findings show a similar trend to the previous studies. Hospital CEO leadership behaviors and employee outcomes were significantly correlated. Correlations showed a significant positive relationship between those hospital CEO exhibiting a transformational leadership style and the job satisfaction of their staffs. The results of multiple regression analysis indicate that the effect of charisma in transformational leadership behaviors is more higher than other variables. Transformational leadership style may be a more effective strategy and have a greater effect on staff outcomes, attitudes and behaviors. The findings of this study reveal implications for efficient hospital management and the importance of understanding relationship between hospital CEO's leadership style and subordinate behaviors in the context of CEO's desirable role and function for hospital strategy planning and future direction.

In June 2011, walnuts (Juglans regia) from orchards in Kimcheon and Muan, in southern Korea, were found to exhibit downy mildew-like symptoms of a foliar disease. Whitish polygonal efflorescence was produced on the abaxial surface of affected leaves and discolored light green blotches on the corresponding adaxial surfaces. In the later stage of disease development, diseased tissues collapsed and became necrotic. Based on morphological and cultural characteristics, the causal fungus was identified as Microstroma juglandis. The sequence of ITS rDNA of the present isolate showed 100% similarity with those of M. juglandis obtained from GenBank databases, thus confirming its identity. Pathogenicity tests were conducted on leaves of walnut seedlings, fulfilling Koch's postulates. The disease has been previously reported in North America, Europe, Oceania and some western Asia. This is the first report of downy leaf spot on walnuts in East Asia.

The purpose of this study was to investigate the effect of group music therapy for at-risk Korean soldiers on the levels of adjustment and stress. The study was conducted at a division of the Korean Army with 7 participants who were classified as "at-risk soldiers" based on the results of a psychiatric evaluation, MMPI-II and a personal interview with a counselor. The participants received 12 hours of group music therapy for three weeks and their scores on stress and adjustment inventories were compared before and after the treatment. The pre and post scores were analyzed with the Wilcoxon test for repeated measures. The results revealed that the overall stress level was significantly decreased while there was no significant improvement in the adjustment levels at p < .05. The research findings and personal remarks from the participants suggest that group music therapy may provide effective support for at-risk Korean soldiers in coping with stress and adjustment to military life.

Thoracic sympathectomy is the radical and definite treatment of palmar hyperhidrosis. From January 1992 to March 1997, 4 patients with recurrent hyperhidrosis underwent resympathectomy via VATS at the Department of General Thoracic and Cardiovacular Surgery, Young Dong Severance Hospital. There were 2 men and 2 women and mean age was 20.0 years. There were moderate to severe adhesions at previous resection site but no thoracotomies were performed. There was no sweating on palms in all cases and all patients were greatly 5,Btisfied with those results postoperatively. In conclusion, recurrent hyperhidrosis was successfully treated with resympathectomy via VATS. In order to prevent recurrence and minimize the postoperative complication, the proper localization of the 2nd sympathetic ganglion and the radical excision of anatomical variation including Kuntz fiber are needed.
