Large corporations have the work and roles of employees clearly defined in accordance with their established internal structure whereas small and mid-sized firms may lack an official job specification or a written job description, causing ambiguity in the role of employees. In IT service companies, especially, there is a relatively large number of tasks requiring one person to play multiple roles and they are often highly dependent on few key players. In this reality where about 80% of the job seekers end up in SMEs, it is therefore necessary to look into how the turnover factors such as job strain and occupational burnout caused by the role ambiguity from extra work affect the turnover intentions of small and medium sized IT service firm employees. The outcome of this study is as follows. First, the relationship between job strain and turnover intention has been examined to find that a weak inverted U shaped relationship exists between role overload, which is a subset of job strain, and turnover intention. Second, the hypothesis based on the competing values framework has been tested that the fitness with organizational leadership and culture would moderate the relationship between job strain and turnover intention and it has been confirmed that the degree of relationship between role conflict and role ambiguity, the subsets of job strain, and turnover intention has changed. In conclusion, in order to discourage turnover intention, it is necessary to increase the fitness with the organization and leadership or generate a sufficient level of strain in case of an organization with low fitness.

Purpose: This aim of this phenomenological study was to describe and understand the experience of spiritual conflict in hospice nurses by identifying the meanings and structures of the experience. Methods: Participants were 12 nurses working for one year or more at hospice units of general hospitals in a metropolitan city and experiencing of spiritual conflict as hospice nurses. Over six months data were collected using individual in-depth interviews and analyzed with the method suggested by Colaizzi. Results: The experience of spiritual conflict in participants was organized into three categories, six theme-clusters, and 13 themes. The participants felt existential anxiety on death and a fear of death which is out of human control and skepticism for real facts of human beings facing death. They also experienced agitation of fundamental beliefs about life with agitation of the philosophy of life guiding themselves and mental distress due to fundamental questions that are difficult to answer. Also they had distress about poor spiritual care with guilty feelings from neglecting patients' spiritual needs and difficulties in spiritual care due to lack of practical competencies. Conclusion: Findings indicate the experience of spiritual conflict in hospice nurses is mainly associated with frequent experience of death in hospice patients. The experience of spiritual conflict consisted of existential anxiety, agitation of fundamental beliefs and distress over poor spiritual care. So, programs to help relieve anxiety, agitation and distress are necessary to prevent spiritual conflict and then spiritual burnout in hospice nurses.

Purpose: This research was an empirical study designed to identify precursors and interaction effects related to nurses' patient identification behavior. A multilevel analysis methodology was used. Methods: A self-report survey was administered to registered nurses (RNs) of a university hospital in South Korea. Of the questionnaires, 1114 were analyzed. Results: The individual-level factors that had a significantly positive association with patient identification behavior were person-organization value congruence, organizational commitment, occupational commitment, tenure at the hospital, and tenure at the unit. Significantly negative group-level precursors of patient identification behavior were burnout climate and the number of RNs. Two interaction effects of the person-organization value congruence climate were identified. The first was a group-level moderating effect in which the negative relationship between the number of RNs and patient identification behavior was weaker when the nursing unit's value congruence climate was high. The second was a cross-level moderating effect in which the positive relationship between tenure at the unit and patient identification behavior was weaker when value congruence climate was high. Conclusion: This study simultaneously tested both individual-level and group-level factors that potentially influence patient identification behavior and identified the moderating role of person-organization value congruence climate. Implications of these results are discussed.

본 연구에서는 화재사례를 기반으로 원적외선 히터에서 출화된 화재의 원인 분석에 관하여 연구하였다. 전기히터의 화재는 열선에 용융 흔적으로 판단하여 과열 사고로 취급하는 오류를 범하기 쉽다. 이에 대해 히터의 화재 원인 규명에 있어서 객관적인 자료를 확보하기 위한 방법으로 정상 제품과 비교하여 다양한 재현 실험 및 분석기기를 이용하여 화재 원인을 분석하였다. 열선에 부착된 용융 흔적은 다른 금속 물질에 의한 층간 단락의 형태를 보이나 SEM/EDX로 성분분포를 분석한 결과 철-크롬-알루미늄이 혼합된 열선의 성분이외에 다른 금속 물질은 발견되지 않았다. 또한 층간단락 및 과전압에 의한 과열 실험을 수행한 결과 정상보다 높은 발열 상태를 보이나 화재 가능성은 없었다. 본 논문에서는 원적외선 히터에서 발생한 화재의 원인 분석을 토대로 하여 소손된 전열기의 화염 특성 및 물리 화학적 특성을 입체 분석하여 전기재해 원인 분석의 과학화에 기여하고자 한다.

Purpose: The purpose of the study was to explore how hospital nurses decide to quit working as professional nurses using the grounded theory method. Method: The data was collected by individual in-depth interviews with 12 hospital nurses who recently resigned from work and it was analyzed using 'constant comparative analysis.' Result: The core category that emerged was "in search of new balance with self, work, and family". Three stages were identified: 1) "unconditionally accepting the working situation of itself," 2) "weighing advantages and disadvantages of working as a hospital nurse", and 3) "redesigning a future". Each stage contains three major strategies. The major strategies of the first stage are "maintaining a learning attitude", "enduring physical burnout," and "enduring unfair interpersonal relationships". The second stage contains "identifying advantages of working", "identifying disadvantages of working", and "comparing the advantages with the disadvantages". Lastly, the third stage includes "reassessing the aim of life", "beginning to construct an alternative life", and "deciding to quit working at a certain point". Conclusion: The results of the study will help nursing administrators in designing and implementing an effective turnover prevention program for nurses by understanding more deeply the process of turnover phenomenon among hospital nurses.

The microstructure and corrosion behavior of commercially dental casting gold alloys were investigated to clarify the effect of burn-out temperature and cooling rate. In the case of water quenching after casting, only the αphase, which is typical dendritic microstructure of golda alloy, was detected. However, the precipitates along the grain boundary were detected only at the slow cooling rate and they increased inversely proportional to the burn-out temperature. This might be due to the time difference which solute atom could diffuse. EPMA and SEM results also demonstrated that the precipitate should be lamellar structure consisted of Ag rich phase(${\alpha}_1$) and Cu rich phase (${\alpha}_2$). In terms of corrosion, the galvanic coupling was formed due to the difference of composition between precipitates and matrix at the slow cooling rate. In the case of water quenching, the critical current density($i_p$) which indicate the degree of corrosion was lowest at $650^{\circ}C$ and below the burnout temperature, $i_p$ increased with it because of the effect of grain boundary segregation. But above the temperature, $i_p$ increased with it. This may be due to the strain field effect by residual thermal stress.

PURPOSE. The purpose of this study is to compare single and three-unit metal frameworks that are produced by micro-stereolithography. MATERIALS AND METHODS. Silicone impressions of a selected molar and a premolar were used to make master abutments that were scanned into a stereolithography file. The file was processed with computer aided design software to create single and three-unit designs from which resin frameworks were created using micro-stereolithography. These resin frameworks were subjected to investment, burnout, and casting to fabricate single and three-unit metal ones that were measured under a digital microscope by using the silicone replica technique. The measurements were verified by means of the Mann-Whitney U test (${\alpha}=.05$). RESULTS. The marginal gap was $101.9{\pm}53.4{\mu}m$ for SM group and $104.3{\pm}62.9{\mu}m$ for TUM group. The measurement of non-pontics in a single metal framework was $93.6{\pm}43.9{\mu}m$, and that of non-pontics in a three-unit metal framework was $64.9{\pm}46.5{\mu}m$. The dimension of pontics in a single metal framework was $110.2{\pm}61.4{\mu}m$, and that of pontics in a three-unit metal framework was $143.7{\pm}51.8{\mu}m$. CONCLUSION. The marginal gap was smaller for the single metal framework than for the three-unit one, which requires further improvement before it can be used for clinical purposes.
