To investigate an effect of sintering atmosphere on microstructure and properties of metallic particle dispersed ceramic based composites, the powder mixtures of $Al_2O_3$/Fe-Ni, synthesized by chemical solution process, were hot-pressed under different atmospheres such as hydrogen or argon gas and different sintering temperature. Hot-pressed composite in a hydrogen atmosphere exhibited less reaction phase of $FeAl_2O_4$ and enhanced mechanical properties than that in an argon atmosphere. Furthermore, decreasing hot-pressing temperature produced a refinement of ceramic matrix and metallic dispersion particles as well as improvement of mechanical properties. The change of mechanical properties in the composites with different sintering conditions was explained by microstructural characteristics relating to reaction phase formation.

The purpose of this study was to examine the relationship between leisure experience and job-attitude and organizational citizenship behavior. And this study indicates how positive emotion affects the relationship between leisure experience and job-attitude and organizational citizenship behavior. The results from this study are as follows: First, leisure experience influenced significantly the positive emotion, the positive emotion was giving positive affection to job satisfaction, organizational commitment, and organizational citizenship behavior. Second, positive emotion mediated between leisure experience and job-attitude and organizational citizenship behavior. This study was giving us implications that positive emotion from leisure experience is more important than leisure activities themselves when we plan 'fun management'.

Purpose: The purpose of this study was to examine the relationship between nurse's perception of organizational characteristics including safety climate and work environment and barrier to medication error reporting. Methods: We surveyed 334 nurses from 7 hospitals. An assessment survey was consisted of modified safety climate scale, practice environment scale and barrier to medication error reporting. The data were collected from September 2012. Descriptive statistics, Pearson correlation coefficient, canonical correlation were used. Results: Organizational characteristics were related to barrier to medication error reporting with three significant canonical variables. The first canonical correlation coefficient was .50(Wilks' ${\lambda}$=0.61, df=32, p<.001), that of the second was .35(Wilks' ${\lambda}$=0.81, df=21, p<.001) and that of the third was .22(Wilks' ${\lambda}$=0.93, df=12, p=.018). The first variate indicated higher perception of safety climate variables and work environment variables were related lower barrier to medication error reporting variables except fear for error reporting. The second variate showed higher perception of 'safety climate between healthcare provider' and higher 'nurse participation in hospital affairs' and 'staffing and resource adequacy' were related to lower 'fear' and 'administrative response' in barrier to medication error reporting variables. Conclusion: Strategies for barrier to medication error reporting and improvement of organizational characteristics including safety climate and work environment should be implemented.

나노크기 금속입자가 분산된 세라믹 나노복합재료는 향상된 기계적 특성과 함께 독특한 전기적, 자기적 특성을 보여주어 새로운 기능성 재료로의 응용가능성을 갖고 있다. 그러나 소결 중의 반응이나 입자성장 등으로 형성된 반응상 또는 조대한 입자상이 세라믹 기지의 입계 등에 존재한다면, 나노크기 금속상 분산에 의한 기계적 특성의 향상과 독특한 기능성 부여라는 장점들이 없어지게 된다. 따라서 요구되는 특성을 구현할 수 있는 금속분산 나노복합재료의 제조를 위해서는 미세조직 제어를 위한 최적의 제조공정 확립과 미세조직과 특성 등의 관계에 대한 연구가 요구된다. 본 연구에서는 기지상으로 A1$_2$O$_3$를, 분산상으로는 저융점 금속이며 일반적인 A1$_2$O$_3$의 가압소결시에 (약 140$0^{\circ}C$) 액상으로 존재하는 금속 Cu를 선택하여 조성이 5 vol% Cu가 되도록 복합재료를 제조하였다. $Al_2$O$_3$와 CuO 원료분말들은 습식 및 건식 볼 밀링을 통하여 균일한 분말혼합체로 제조되었다. 혼합분말은 열간가압소결기 내에 장입한 후 35$0^{\circ}C$에서 30분 동안 H$_2$가스를 흘려주며 CuO를 Cu로 환원 처리하였다. 계속해서 H$_2$분위기를 유지하며 승온한 후, 각각 1000-145$0^{\circ}C$에서 분위기를 Ar 으로 치환하였다. 소결은 145$0^{\circ}C$에서 30 ㎫의 압력으로 1시간동안 행하였다 소결한 시편들은 직사각형 형태로 가공하였으며 표면은 0.5$\mu\textrm{m}$의 다이아몬드 입자로 연마하였다. XRD, SEM 및 TEM을 이용하여 상분석 및 미세조직관찰을 행하였다. 파괴강도는 3중점 굽힘 법으로 (3-point bending test) 측정하였다. 이때 시편 하부의 지지 점간의 거리는 30mm, cross-head 속도는 0.5 mm/min으로 하였고 5개의 시편을 측정하여 평균값을 구하였다.

This research analyzed job satisfaction for improvement in job satisfaction of forest interpreters and effective management. Interpreters felt satisfied with their job with a mean satisfaction score 3.41 out of 5 but unsatisfied with pay and job benefits. Job satisfaction showed significant differences in interpreting field, agencies and working period. Results from factor analysis, job satisfaction classified into four factors; team atmosphere, level of compensation, job conflict and working environment. And interpreters more satisfied in team atmosphere and working condition than level of compensation and job conflict. Also this study showed related variables to job satisfaction. Team atmosphere was related with working period and agency, the level of compensation was also related with agency and the working environment is in relation to agency and interpreting field.

Man-made disasters are disastrous event, which can be reduced the damage through preventive measures and thorough inspections, unlike natural disasters. Thus, safety consciousness of citizens is not only important, but also safety consciousness of security guard who are involved with facility safety management. In other words, safety consciousness and fostering professionalism of security guards could reduce the damage, including human disaster and it enables the effective safety management. Therefore, this study selected the training and the organizational safety as variables with the influencing factors for improving the disaster safety consciousness of facility guard. After the analysis, the following results were confirmed. First, the training content and its environment would have a significant impact on the disaster safety consciousness. Second, organizational safety would have a significant impact on disaster safety consciousness. In other words, the improvement of training program and the formation of safety culture in organizational level will have a positive impact on the disaster safety awareness and enable effective safety management.

Purpose: The purpose of this study was to determine the effect of needs for professional development and organizational climate on organizational socialization of clinical nurses. A cross-sectional analysis were performed to assess the factors affecting organizational socialization. Methods: The data used in this study were obtained from clinical nurses who were employed in a hospital (N=606). Using multiple regression, we tested variables to assess their effects on organizational socialization in this sample. The data were analyzed using descriptive test, t-test, ANOVA, Pearson correlation coefficiency and stepwise multivariate regression. SPSS 17.0 program was utilized for data analysis. Results: The mean scores of organizational socialization, needs for professional development and organizational climate were statistically differed by career ladder, educational level and position. Organizational socialization had significant positive correlations with the needs for professional development (r=.332, p<.01) and organizational climate (r=.523, p<.01). Those variables including career ladder explained 33.4% of organizational socialization. Conclusion: Our findings indicate that organizational socialization of clinical nurses could be enhanced by meeting the needs for professional development and organizational climate. Developing innovative educations for encouraging clinical nurses' carrier development and creating a positive organizational climate are mandated for clinical nurses to have constructive organizational socialization.

본 연구에서는 SM20C를 모재로 하여 입경의 크기가 다른 3종의 복합조직강을 제작 동일한 분위기에서 저 및 고사이클 전영역에 걸쳐 피로특성을 검토하고져 한다. 제일보는 그 중 저사이클특성에 대한 보고이다. 일반적으로 저사이클 피로현상은 재 료가 탄소성 상태하에서 전위, 미소크랙, 보이드(void) 등의 인자가 복합적으로 작용 하여 발생함으로 변형률속도, 제어파형, 온도, 시험방법 및 분위기에 따라 많은 영향 을 받는다. 따라서 본 연구에서는 두가지 실험방법을 사용, 응력-변형율거동을 검토 복합조직강의 피로특성과 입경크기가 피로거동 및 강도에 미치는 영향을 비교 고찰하 였다.
