Purpose: The purpose of this study is to investigate the role of social support in the experience of job stress among hospital nurses. Method: This study was carefully designed to overcome methodological shortcomings found in past research, and examined two organizational effectiveness variables(job satisfaction and organizational commitment) as outcome variables. The sample used in this study consisted of 602 nurses from 5 general hospitals. Data were collected with self-administered questionnaires and analyzed using hierarchical regression and LISREL technique. Result: It was found that: (a) three job stress variables(workload, role conflict and conflict with other medical staff) have negative effects on job satisfaction and organizational commitment; (b) social support have positive main effects on the two output variables; (c) the negative effects of job stress variables on job satisfaction and organizational commitment are not buffered by social support, and (d) social support mediates the effects of job stress on job satisfaction and organizational commitment, and the size of the mediating effects is small. Conclusion: Further research needs to be done to further refine this study.

This study investigate the influence of resilience on organizational commitment using social support as a mediating variable for kindergarten and childcare teathers. The subjects were 630 kindergarten and childcare teathers. The collected data were analyzed by Pearson's correlation as well as single and multiple regressions that used SPSS Win 19.0. The results were as follows: (1) The resilience was significantly associated with organizational commitment of kindergarten and childcare teachers. (2) The resilience was significantly associated with social support of kindergarten and childcare teachers. (3) The resilience was not significantly associated with organizational commitment of kindergarten and childcare teachers, controlled by social support. The results showed the social support was more important variable affecting organizational commitment of kindergarten and childcare teachers than the resilience. As a result, teachers have to be strengthened for support of social emotion that helps to control of their emotional condition and social evaluation that estimates their role positive under administration system.

Purpose: The study is to identify a correlation among hospital nurses' emotional labor, social support and organizational commitment and to analyze the effects on organizational commitment. Methods: The participants are 300 nurses working at two general hospitals located in Gyeonggi-do, who agreed to join the study. Data collection were done from July to September in 2014. The collected data are analyzed a descriptive statistic, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient, and multiple regression and SPSS/WIN 15.0 Program was used in the process. Results: Organizational commitment was negatively correlated with emotional works but it was positively correlated with social support. The factors affecting organizational commitment were informational support and evaluative support which were sub-domain of social support as well as level of emotional expression which was a sub-domain of emotional works, their positions and level of education. Conclusion: To increase the level of an organizational commitment, a method of coping in difficult situations and information relating to private assessments is recommended. Also, the organization should prepare a plan that members can properly manage their emotions face-to-face with clients.

치주질환은 치아 지지조직의 파괴로 튿정 지어지는 감염성 질환으로서 이것은 주로 조직의 교원질 성분을 분해시키는 MMP(matrix metalloproteinase)에 의해 이루어진다. 한편, 여러 연구에서 당뇨병과 치주질환의 심도와의 관계에 대한 논의가 있어왔으며 당뇨병이 치주염을 포함한 구강 감염에 대한 감수성을 증가시키며 역으로 만성 치주염의 염증성 매개물질에 의해 인슐린 작용이 방해받을 수 있음을 보고하였다. 본 연구의 목적은 만성 치주염 환자와 제 2형 당뇨병을 동반한 만성 치주염 환자의 치은조직에서 MMP-13과 elastase의 발현 양상을 비교하여 병리 기전의 차이점을 규명하고, 두 단백질간의 상호관계를 알아보기 위한 것이다. 경북대 병원 치주과에 내원한 환자의 비당뇨 환자의 정상 치은 부위, 비당뇨 환자의 만성 치주염 부위, 제 2형 당뇨병 환자의 만성 치주염 부위에서 각각 8개의 변연 치은을 채득하여 액화 질소에 급속 동결시켰다. 모든 조직 샘플에서 동량의 단백질을 western blotting을 통해 분석하여였고, densitometer를 이용하여 정량한 후 ANOVA 분석으로 통계처리 하였다. 결과분석에서 MMP-13은 제 2형 당뇨를 가진 환자의 염증성 조직에서 가장 높게 발현되었고 전신적으로 건강한 환자의 염증성 조직과 정상 조직에서는 유사한 양상을 보였으며 그 차이는 통계적으로 유의하였다. 또한 elastas는 그룹간에 유의한 차이 없이 유사한 양상으로 발현되었고, 염증성 조직에서도 당뇨병의 유무에 관계없이 유사하게 나타났다. 한편 조직내 MMP-13과 elastase의 발현 양상간에 유의한 상관관계는 보이지 않았다. 결론적으로 MMP-13은 당뇨병을 동반한 환자의 치은 염증초직에서 유의하게 증가되어 나타났으며, 전신적으로 건강한 환자의 염증조직과 당뇨를 동반한 환자의 염증조직에서 MMP-13과 elastase의 발현양상은 큰 상관관계가 발견되지 않았다.

Drawing on costly signaling theory and self-enhancement motive, this study examines the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. In addition to the individual characteristic, this study considers job characteristics as conditional factors, and especially proposes the moderated mediation model in which job complexity and variety moderate the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. To prove these hypotheses, empirical analyses are conducted with 166 dyad samples collected from various industries. As predicted, individuals with high proactive personality are more likely to become involved in knowledge sharing behavior, and this behavior increases organizational recognition rated by their supervisors. Moreover, job complexity and variety moderate the positive relationship between proactive personality and organizational recognition is mediated by knowledge sharing behavior. These results reveal the motive in knowledge sharing and the boundary condition that is necessary to increase such behavior. The study findings will ultimately contribute theoretical and empirical implications to the knowledge management literature.

인센티브는 조직 내 개인의 동기와 행동에 영향을 미쳐 조직의 목표를 달성하는 데에 중요한 역할을 한다. 기존 문헌에서는 이러한 관점에서 개인의 다양한 동기를 충족시킬 수 있는 경제적, 사회적 보상에 대하여 논의해왔다. 반면, 직업안정성이 개인에게 기업가적 동기를 가진 개인에게 어떠한 인센티브로 작용할 수 있는지에 대한 내용은 간과된 측면이 있다. 본 연구는 창업휴직제도가 직업안정성이라는 비금전적 인센티브로 작용하여, 기업가적 동기를 가진 직원들의 기업벤처링(Corporate Venturing) 활동 참여에 긍정적인 영향을 줄 수 있는지 여부를 조사한다. 본 연구는 전통적인 인적자원관리 문헌에서 비금전적 인센티브를 통해 개인의 일탈과 이직을 방지하려는 관점과는 달리, 개인이 일을 중단하는 것을 허가하는 '창업휴직제도' 자체가 비금전적 인센티브로서 개인이 혁신 성과를 증가시킬 수 있다는 점에 집중한다. 정부출연연구소 내부 기업벤처링 프로그램에 참여한 세 명과의 개인 인터뷰를 통해 이러한 가설을 지지할만한 단서를 발견하였으며, 이를 바탕으로 향후 실험 연구를 통해 실증 분석을 진행하고자 한다.

Recently, flexible denture is widely used with some advantages such as esthetics, flexibility and biocompatibility. However, there is an opposite opinion about stability because of the movement of denture by the material's flexibility. As the denture moves to tissue surface during mastication, it irritates the supporting tissue. It can lead to trauma and rapid resorption of residual ridges if this irritation lasts for a long time. In this case, the patient has used flexible denture with insufficient stability, retention and support for several years and thus continuous irritation of the supporting tissue resulted in palate bone exposure. The patient discomfort and palate bone exposure underwent improvements by the new denture with stability and retention. A careful case selection for flexible denture, regular checkup and proper treatment are necessary to prevent the side effects.

The purpose of this study is to provide basic data for human resource management and efficient hospital management of organization by checking the effect of psychological contract of nurses on voice behavior. It is a descriptive research study that survey nurses who consented responded to the research questions. As a result, nurse practitioners showed a low level of perceptions of organizational commitment, psychological contracts, transactional contract and relational contract. There was a positive correlation between transactional contract and constructive voice(p<.05), and there was a negative correlation between relational contract and destructive voice(p<.05). Therefore, it is necessary to establish a system in which internal and external compensation can be made according to changes in roles of nurses in order to carry out new polices and organizational changes. It is also necessary to improve the organizational culture so that nurses can actively participate in policy and organizational change.

Traumatic injury of tooth in children is commonly occurred problem. It is classified into tooth, periodontal tissue, supporting bone, soft tissue injury by it's area and extent. Among the periodontal tissue injuries, traumatically intruded teeth are common in anterior maxillary area, though the occurrence rate is rather low, the pulp and supporting tissue injury is possible by vertical impact. The treatment method of traumatically intruded teeth is various. Observation on the spontaneous reeruption for 3-4 weeks is recommended if the traumatized teeth are deciduous teeth or slightly intruded immature permanent anterior teeth. If this did not occur because the extent of intrusion is severe or the traumatized teeth are mature permanent anterior teeth, orthodontic traction is applied by fixed/removable appliances. At this time, light and continuous force is applied for the extrusive movement of the intruded teeth. When above procedures are impossible, surgical repositioning and fixation is recommended. In these cases, we performed conventional endodontic therapy for pulp necrosis and orthodontic traction with fixed appliance. We obtained satisfactory results and will report that.
