The global economic growth rate has been slowed due to changes in the economic and social environment related to the recent trends in the construction market and construction industry, prolonged inflation, intense tensions among countries, and increased interest rates. Since the workers in the construction industry, due to the nature of the industry, move to another site after the completion of an awarded project rather than staying for a long time while performing work at one workplace, various issues are brought out such as poor working environment resulting from unfairness in construction contracts, aging of workers, their anxiety, and job instability. The previous studies on the turnover intention of construction industry workers mainly dealt with external aspects such as leadership, job embeddedness, and organizational citizenship behavior, while the psychological impact was overlooked. The purpose of this study was to develop a measure to reduce or alleviate turnover intention of construction industry workers by verifying empirically the relationship among psychological capital, organizational commitment, and turnover intention among them. For the purpose, whether psychological capital influences organizational commitment and turnover intention, the impact of organizational commitment on turnover intention, and whether organizational commitment has a mediating effect in the relationship between psychological capital and turnover intention, among 310 construction industry workers in the metropolitan area. The results are as follows: First, hope and self-efficacy were found to have a negative (-) effect on turnover intention, while resilience and optimism from psychological capital did not have a significant effect. Second, hope, resilience, and optimism from psychological capital were found to have a positive (+) effect on organizational commitment, while self-efficacy from psychological capital had no significant effect. Third, organizational commitment was found to have a significant mediating effect on the relationship between hope from psychological capital and turnover intention. The results of this study showed that, in construction industry workers, psychological capital affects turnover intention through the mediating effect of organizational commitment. While previous studies mainly considered external influences on the turnover intention of construction industry workers, this study has academic implications in that it sought to strengthen organizational commitment and alleviate turnover intention by approaching psychological aspects. As a practical implication, it was found that higher self-efficacy and hope for work in the organization, from psychological capital, in the construction industry workers were found to lower turnover intention through job performance in a psychologically stable state. It is considered, therefore, that various systems, including job autonomy and flexible work, should be established to improve self-efficacy and hope.

The effects of dietary conjugated linoleic aicd on pork quality was investigated using sixty four pigs. CLA was synthesized by alkaline isomerization method with corn oil. Pigs were devided into 4 treatment groups(16 pigs/group) arid subjected to one of four treatment diets(0, 0.1, 0.2, and 0.3% CLA diets) for 2 weeks before slaughter. Pork loin and belly were collected from the animals(105∼110kg body weight) slaughtering at the commercial slaughter house. Pork loin and belly meat were aerobic packaged and then stored during 2. 5. 8. 11 and 13 days at 4$\^{C}$ refrigerator. Samples were analysed for meat color, texture and sensory characteristics. There were no diference in meat color(L*, a*, b*), texture and sensory property among control and CLA treatment (s), and no changes as the storage period passed. This results mean that feeding CLA to pork doesn't change the meat color and texture of the pork what consumers consider when they buy some meat. Especially, feeding CLA to pork didn't transform sensory property of the pork. We considered these result as no problem in the pig fed with CLA.

지식 정보화 사회에서 지식경영의 중요성이 부각되면서, 학계의 다양한 연구와 기업의 의욕적인 투자가 진행되어 왔다. 그러나 지식경영과 관련된 기존 연구들은 다음의 한계점을 드러내고 있다. 즉 기존의 연구는 조직 내 구성원의 관계와 같은 구조적인 부분에 한정되어 지식경영의 주체인 개인의 개성(personality)에 대한 고려가 부족하고, 또한 구성원들의 동기를 고취시키기 위해 경쟁을 유도하는 환경이 지식공유에 주는 부정적인 영향을 간과하고 있다. 따라서 본 논문은 첫째, '개인간의 관계를 바탕으로 한 지식 공유에 있어서 자존감(Self-esteem)과 성취지향성(Conscientiousness)이 어떠한 영향을 주는가?', 둘째, '경쟁을 장려하는 것이 지식공유에 도움이 되는가?' 라는 문제에 초점을 맞추고 있다. 본 연구에서 KAIST 테크노경영대학원의 특정 수업의 수강생 32명을 대상으로 쌍방관계 데이터(dyadic relational data)를 수집하여 다중회귀분석(multiple regression Analysis)을 수행한 결과, 자존감은 개인간의 지식공유에 음의 조절변수(negative moderator)로 작용할 것이라는 가설이 지지되었고, 성취지향성은 개인간의 지식공유에 있어서 양의 조절변수(positive moderator)로 작용할 것이라는 가설은 지지되지 않았다. 마지막으로 조직 내의 경쟁이 심화될수록 개인간의 지식공유는 감소할 것이라는 가설은 지지되었다. 본 연구는 기존의 연구들과는 달리, 자존감이 높은 인재에 대한 보다 새로운 시각이 필요하다는 점과 경쟁을 장려하는 지식 경영 방법론에 대한 재고가 필요하다는 것을 실증적으로 보여주고 있다.

This study aims to investigate the relationship among public service motivation, hospital organizational culture type, job-esteem, and turnover intention of public hospital nurses. A cross-sectional study was conducted on 124 nurses at four public hospitals in the Gyeonggi Province (Icheon, Anseong, Suwon, Paju). Data were analyzed using descriptive statistics, t-tests, ANOVA, and Pearson correlation coefficient. Mann-Whitney U test and the Kruskal-Wallis test were used with the Bonferroni test for post hoc comparison when the data were not normally distributed. The turnover intention of the subjects was public service motivation (r=-.30, p<.001), affiliative culture (r=-.28, p=.002), innovative culture (r=-.34, p< .001) and task culture (r=-.30, p=.001) were negatively correlated. Study findings suggest that public service motivation must be increased to reduce the turnover intention of nurses in public hospitals.

목적 Pheochromocytoma of the Adrenal gland Scaled Score (PASS) 시스템과 면역화학염색 등을 통한 갈색세포종 및 부교감신경절종의 악성화 예측인자가 제시되고 있으나 명확한 병리학적 또는 분자생물학적 예측인자는 밝혀진 바 없다. 본 연구에서는 임상적, 병리학적 분석을 통해 갈색세포종 및 복강내 부교감신경절종의 악성화 예측인자를 확인하고자 하였다. 대상 및 방법 1990년 1월부터 2010년 12월까지 서울대학교어린이병원에서 수술적 절제 후 병리학적으로 갈색세포종 및 복강내 부교감신경절종으로 확진된 20명의 18세 이하 소아 환자를 대상으로 임상적 특징을 분석하였고, PASS 시스템에 따른 병리 슬라이드 판독하였다. 세포활성도를 반영한다고 알려진 유전자에 대한 항체 중 Ki-67, p53, bcl-2, mdm-2, cycline D1, p21, p27을 이용해 면역 화학검사를 한 후 결과를 확인하였다. 결과 20명의 환자 중 갈색세포종은 14명, 복강내 부교감신경절종은 6명이었다. 악성화는 각각 4명, 3명에서 관찰되었다. 혈관 침범, 주변부 지방조직 침습, 세포분열 증가가 통계적으로 유의한 악성화 예측인자였으며(각각 p=.007, .031, .031), 갈색세포종만 분석하였을 때도 통계적으로 유의하였다(각각 p=.033, .003, .019). PASS 시스템은 악성화를 예측하는데 있어 통계적으로 유의하지 않았으며, 혈관 침범, 주변부 지방조직 침습, 세포분열 증가를 항목으로 하여 새롭게 만든 병리 스코어 시스템은 악성 환자군과 양성 환자군 사이에 통계적으로 유의한 차이를 보였다(p< .001). 악성과 양성 질환 사이의 면역화학염색 결과에서 유의한 차이는 없었다. 결론 소아에서 갈색세포종 및 복강내 부교감신경절종의 악성화 예측인자로 혈관 침범, 주변부 지방조직 침습, 세포분열 증가를 이용할 수 있다. 소아에서 PASS시스템으로 악성화를 예측할 수 없었으나, 새로운 병리스코어 시스템으로 악성 환자군을 예측할 수 있었다. 면역화학검사 결과 세포 활성도를 반영하는 인자들은 악성화를 예측할 수 없었다.
