This study was conducted to understand the effects of job stress, empowerment, and organizational commitment of nursing care workers on burnout For this study, nursing care workers working at long-term care institutions in Gwangju and Jeonnam were conducted. As a result of the study, it was found that excessive role, role conflict, and role ambiguity perceived by nursing care workers had a positive effect on burnout. Individual competencies, job relationship competencies, and organizational environment competencies were found to negatively affect burnout. In addition, it was found that emotional and normative commitment negatively affected burnout, and continuous commitment had a positive effect. Overall, it was found that job stress, empowerment, and organizational commitment had an effect on burnout in order. Based on the results of these studies, it is necessary to establish a fair personnel management system, such as assigning roles appropriate to the nursing care worker's ability and aptitude, selecting, placing, and evaluating targets. It is necessary to create a systematic work environment such as training and provision of supervision. In addition, nursing care workers should relieve stress that occurs in the process of performing their duties, and provide an appropriate rest area for leisure to facilitate work.

The purpose of this study was to identify the relationship among beginning early childhood teachers' stress coping strategies, role performance, and self leadership. The subjects in this study were 491 beginning early childhood teachers working in kindergarten and child care centers across the country. Stress coping strategies questionnaire(Chang-Soon Park, 2005) and role performance questionnaire(Bog-Mae Park, 2011), and self-leadership questionnaire(Dong-Hyen Park,2014) were used for this study. For the research analysis, frequency, Cronbach's ${\alpha}$ coefficient, and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that passive stress coping strategies does not have statistically meaningful influences on role performance, but active stress coping strategies have statistically meaningful positive influences on role performance. Also, 491 beginning early childhood teachers' active stress coping strategies have statistically meaningful positive influences on role performance through the mediation of self leadership. That is, the results explain that the higher the self-leadership of beginning early childhood teachers is, the higher the role performance that they have experienced is. It shows that beginning early childhood teachers'self leadership mediates partially between active stress coping strategies and role performance. Through this study, it is possible to provide basic information to configure the subject content that enhance their self-leadership and develop active stress coping attitudes in a curriculum for beginning early childhood teachers.

This study examined the causal relationship between work environment and job satisfaction/turnover intention through statistical analyses using the statistics programs SPSS(18.0) and AMOS(18.0) of over 268 business owners operating small sized Chinese restaurants in the Busan and Gyeongnam area. Research results found that among the business owners of small sized Chinese restaurants, 130 were owner/chefs (48.5%), 63 engaged in hall serving (23.5%), and 75 were in delivery (28.0%). It was also found that while the physical environment had a positive effect on work pride and economic satisfaction, sale stress had no effect on work pride and economic satisfaction. In addition, the physical environment and mental labor environment showed a positive effect (+) on turnover intention, although job satisfaction (work pride, economic satisfaction) showed a negative effect (-) on turnover intention. Such result leads to the conclusion that for business owners of small sized Chinese restaurants, sale stress experienced during the course of business serves as a factor weakening job satisfaction while increasing turnover intention to a greater extent of the physical environment (kitchen facilities and hall facilities). Thus, it seems that practical business training, such as service training, is a greater necessity for business owners of small sized Chinese restaurants, as opposed to an improvement of restaurant facilities.

Purpose - The purpose of this study is to identify team commitment affecting employees' innovative activities and factors affecting team commitment including empowerment by leaders and job enrichment factors. In other words, so as to explain outcome variables of innovative activities, this study aims to emphasize employees' attachment roles towards their groups within nomological network, and identify the motives encouraging employees' innovative activities. The research purpose is significant due to the realistic situation of hotel industry. The reason why innovative activities are important can be found in recent changes of business environment. Also, unlike other various studies on precedence factors encouraging employees' innovative activities, this study classified those precedence factors into job and leader characteristics, and it emphasized the importance of team commitment as the process that job and leader characteristics are connected to innovative activities. Research design, data and methodology - The survey for this study was conducted during October 6^th ~ November 10^th in 2014 to the employees who are working in 5-star hotels in Korea. As for the selection of hotels and sampling method, convenience sampling method was used to the employees in 5-star hotels. Self-report method was used in the survey, judging that the employees' characteristics would be relatively homogeneous. 311 questionnaires were distributed in total, and 275 reponses were collected. After excluding the missing and unreliable responses, 245 questionnaires were used in the research. SPSS and AMOS programs were used for the analysis. Results - First, empowering leadership had positive effects on hotel employees' team commitment. It indicates that hotel employees are more committed to their team when their leaders set examples, provide information, and involve employees in decision-making process. Second, as a result of the relationship analysis in task diversity, task significance, task identity and team commitment, task diversity and task significance had significant effect on team commitment, while task identity had no significant effect on team commitment. It indicates that team commitment is enhanced when the employees can conduct diverse types of jobs and get more opportunities to talk with the guests. Also, the repetition for the same jobs in hotel rooms and the space for preparing food and beverage do not lead to team commitment, even though the employees fulfill their duties to the end. Third, hotel employees' team commitment has positive effect on their innovative activities. It indicates that employees voluntarily conduct innovative activities when they are attached to their team and identifies themselves with the team. Conclusions - There are theoretical and practical implications in this study. First, in terms of the theoretical perspective, this study proposes structural framework in team commitment, and it identifies the psychological mechanism in team commitment from the aspect of social exchange, which resulted in identification of precedence factors related to team commitment. In addition, this study presents new possibilities for relevant studies about team commitment by examining the effect on team commitment when the importance of innovative activities is emphasized in recent business environment.

Background : In April 6, 1990, a male researcher who has worked at a research unit at the Basic Research Building of Seoul National University(SNU) College of Medicine admitted to SNU Hospital due to persistent fever. He was diagnosed serologically as hemorrhagic fever with renal syndrome(HFRS). Another female researcher in the same unit was also diagnosed as HFRS at the same hospital several days later. Epidemic investigation of HFRS was conducted to determine the magnitude of the problems since these two cases were strongly suspected to have laboratory-acquired infections of HFRS. Methods : All researchers and employees working at the Basic Research Building(BRB) of SNU College of Medicine as of April 1, 1996 were recruited for the study, information on symptoms of HFRS and history of contact to experimental animals were collected by self-administered questionnaires and serological tests among study subjects were also conducted by indirect immunofluorescent antibody(IFA) to hantavirus. The experimental animals were also serologically tested for infection with hantavirus by IFA. Results : Among 218 surveyed, six researchers and an animal caretaker had hantavirus antibodies above 1:20 in IFA titer. Five of seven sero-positive subjects had antibodies above 1:640 in IFA titer and had shown clinical symptoms compatible to HFRS during Jan. 1 to Apr, 20, 1996. The sero-positive persons had handled animals more frequently than sero-negative persons (OR, 19,68; 95% Cl, 1.11-350.40) and handling animals at the animal quarter at School of Public Health(SPH) had shown consistently higher risk to get infected with hantavirus irrespective of types of animals handled (OR, 4.90-6.37). Sero-positivity of rats of the aniamal quarter at BRB was 30-60%, whereas 80% of rats at SPH tested were shown sero-positivity. Conclusion: There was a epidemic of HFRS in research units of a medical school during the period from Jan. through Apr, Further investigation is needed to determine the extent and the mode of transmission of the laboratory-acquired infection with hantavirus in other research facilities.

This paper addresses questions on the marginalized position of youths of 'Gangbuk' and elucidates how they construct their own identities in the individual trajectories of everyday life. Three years of research, including participatory observation and in-depth interviews, was conducted on nine students from Northeastern district of Seoul. The research also adopted reflexive photography interview method in order to encourage the informants to actively participate in the research. The result illustrates the diversity of the everyday life experiences. More 'marginalized' youths from middle to lower class background had to endure the burdens of their daily lives without programs. Still, they were elaborating their own cultural taste and positive self-narratives at the periphery of the mainstream culture, by practicing music, online community activities and bodily performances. They had to negotiate the crucial turn of life after their graduation, when they entered into the harsh social competition with limited resources. We observed how they gradually assimilate the identity of the 'working youth', some of them developing a positive valorization of their experiences labor. Findings underline the active role of the cultural practices in the making of class identity of the youth and the necessity of researches situating the making of class identity and the reproduction of the class for the youth in the larger geography of class culture in the contemporary Korean society. Lastly, it is argued that these youths should not be considered as determined subjects, who reproduce already established class identities, but as active agents of their lives who deserve more respects and attentions from the society.

This study aims at empirically clarifying the relationship between power and the interpersonal conflict, including nurses' understanding of their relative power, the causes of interpersonal conflicts with the nurses, and strategies to resolve conflicts, in order to understand how nurses' relative power affect their conflicts. For the empirical survey, the population was defined as all the nurses working at a medical organization in Seoul, Korea. 1083 nurses were selected as the sample for the questionnaire survey and statistical analyses. For the sampling, 32 medical organizations were selected by a stratified random method and sub-samples were arbitrarily drawn from each organization to obtain the final sample of 1083 nurses who responded to the questionnaire designed by the reseacher. According to the result of the study, most nurses experience conflict more than once a month, and 70.4% of the respondents answered that interpersonal conflicts were directly or indirectly caused by power relations. which indicates that they perceive power relations as the main cause of interpersonal conflicts. Nurses experienced the most conflicts with interns and residents(29.7%), then patients and their families(24.3%), higher-positioned nurses(12.3%), nurse colleagues(7.7%), lower-positioned nurses(6.5%), and staff doctors(5.1%). If we classify these into three groups. the frequency of the conflicts, from most frequent to least. is in the order of doctors. nurses, and patients. In terms of relative power, nurses perceive that they have greater power than patients and their families, lower-positioned nurses, and nurse colleagues. In contrast, nurses perceive that they have less power than interns and residents, higher-positioned nurses. and staff doctors. Among these groups. nurses perceive that they have the most power over patients and the least over staff doctors. These results indicate that nurses tend to experience more conflicts with members of groups that are stronger than themselves in terms of relative power, Nurses use positive strategies such as the compromise strategy(32.3%) or the collaboration strategy (20.3%) to manage conflicts, more than other strategies. However, they use avoidance or competition strategy more at the earlier stage, compromise strategy more in the mid stage, and collaboration strategy more at the later stage of the interpersonal conflict. In relation to power, nurses use the collaboration strategy or the compromise strategy more when their perceived power is greater than or equal to their counterpart's, and they use the avoidance strategy or the accommodation strategy if their power is less. In terms of source of power, nurses' perceived relative power is greater in the order of referent power. expert power, reward power, legitimate power. and coercive power. where referent power is perceived as having the greatest power and coercive power is least. Most nurses(69.3%) used their power to resolve a conflict. with positive outcomes. Expert power was used most frequently. Overall. this study strongly indicates that the enhancement of power of nurses to have equal power relations with doctors would heighten the success of conflict resolution, since power is the main cause of conflicts. Specifcally. nurses experience most conflicts with doctors against whom they perceive the greatest gap in power. and the choice of a conflict management strategy depend upon their power relations.

The working mechanism of bisphosphonate on bone cells is unclear despite its powerful inhibitory activity on bone resorption. The differentiation and activation of osteoclasts are essential for bone resorption and are controlled by the stimulatory RANKL and inhibitory OPG molecules. Teeth exhibit a range of movement patterns during their eruption to establish their form and function, which inevitably accompanies peripheral bone resorption. Hence, the mandible, which contains the teeth during their eruption processes, is a good model for revealing the inhibitory mechanism of bisphosphonate upon bone resorption. In the present study, RANKL and OPG expression were examined immunohistochemically in the mandible of rats with developing teeth after alendronate administration (2.5 mg/kg). The preeruptive mandibular first molars at postnatal days 3 to 10 showed the developing stages from bell to crown. No morphological changes in tooth formation were observed after alendronate administration. The number of osteoclasts in the alveolar bone around the developing teeth decreased markedly at postnatal days 3, 7 and 10 compared with the control group. RANKL induced strong positive immunohistochemical reactions in the dental follicles and stromal cells around the mandibular first molar. In particular, many osteoclasts with strongly positive reactions to RANKL appeared above the developing mandibular first molars at postnatal days 3 and 10. Immunohistochemical reactions with RANKL after alendronate administration were weaker than the control groups. However, the immunohistochemical reactivity to OPG was stronger after alendronate administration, at postnatal days 3 and 10. These results suggest that alendronate may decrease bone resorption by regulating the RANKL/OPG pathway in the process of osteoclast formation, resulting in a delay in tooth eruption.

Purpose: We conducted a descriptive correlational study to determine a relationship between nurses' awareness of good death and attitudes toward terminal care, which in turn could be used as basic data for improvement of the quality of terminal care at geriatric hospitals. Methods: From April 3, 2013 through April 22, 2013, data were collected from 230 nurses working at geriatric hospitals. Results: Nurses' attitudes toward terminal care showed no significant correlation with awareness of good death, but it was positively correlated with a sense of closeness, a subfactor of awareness of good death. There was negative correlation between emotions regarding a deathbed, a subfactor of attitudes of nurses in charge of terminal patients, and awareness of good death. We found positive correlation between terminal care performance and awareness of good death. Conclusion: This study warrants the need for nursing education catered to characteristics of geriatric hospitals and development of diverse intervention strategies to help them to attain a positive attitude toward death by familiarizing themselves with the concept of good death and enhancing job satisfaction.

The big issue of mathematics education in 2009 revised curriculum is to introduce story-telling in math textbook and to aim toward the math that students can learn easily and interestingly. Therefore, this study examine the perception of middle school teachers in working with story-telling, analyze actual utilization of story-telling in class and provide the basic materials for effective practical application. After making questionnaires to check the real conditions of the story-telling and asking math teachers in charge of the first and second graders, this research came to the conclusion as follows. First, the teachers who took part in this research showed positive perception in story-telling textbook the practical use of a variety of materials and the improvement of thinking faculty and creativity. Second, math teachers made use of a variety of storytelling data and especially reflection media in class, but this was limited in introductory part. Mathematic concept was delivered mainly through the activities of exchanging questions and answers between the teachers and students. Third, students showed positive reaction about story-telling class on the whole. For example, they understood the concept easily and they could apply it in real life. However, story-telling failed to bring the attention and interest of math itself. Therefore, teachers' ability is needed in the way that math knowledge and concept should be formed and expressed interestingly.
