During practices of traffic management, the performance achieved was determined by traffic practitioners' ability of decision and knowledge as well as traffic equipments assisting the practitioners. Therefore, sometimes self-evaluations done by the traffic practitioners in a specific traffic organization can be used to indirectly evaluate the traffic management organization. The present paper is to evaluate a specific highway agency using self-evaluations performed among different highway agencies including one Japanese highway agency. The result indicated that the agency is superior to other agencies in characteristics such as performance, activity, preparation for the future, and customer orientation. For more detailed-branch based study, the responders were divided into their belonged branches like headquarter, regional headquarter, maintenance office and research center. The results provided that various deficiencies of traffic management were found and could be improved in the future.

This paper examines the effects of compassion experienced through orchestral service activities on the psychological well-being and self efficacy of the members and empirically verifies the effects of psychological well-being and self efficacy on the dependent variables. This study also demonstrated the mediating effects of psychological well-being and self efficacy on the relationship between compassion and job performance experienced in the orchestra organization. In this study, we surveyed the orchestra members of Seoul and Gyeonggi provinces. The total number of research subjects was 300, and the survey group was composed of 8 groups, 5 groups in Seoul and 3 groups in Gyeonggi Province. The survey was conducted from September 1, 2017 to September 30, 2017 by researchers who visited each group, explored the research method and research contents to the commanders of each group, and surveyed them again. The hypothesis was verified by analyzing 292 copies of the 300 copies of the collected questionnaire, excluding 8 copies of the fraudulently responded questionnaire. The results of this study are as follows: First, it is demonstrated that the napping experience in the orchestra organization positively affects the psychological well-being and self efficacy. Second, psychological well-being and self efficacy have positive effects on job performance. Third, mediating effects of psychological well-being and self efficacy have a significant influence on the relationship between compassion and job performance.

This research examines the effect of perception of creating shared value (CSV) activity on the organizational commitment and job satisfaction of non-permanent (part-time) employees in order to understand the importance of CSV. In order to accomplish this study, 559 questionnaires were used for final analysis. SPSS 25.0 was used for statistical analysis. The analysis revealed that perception of corporate CSV activity had a positive effect on job satisfaction of non-permanent(part-time) employees. In particular, it had a positive effect on the relationships between the perception of CSV activity and organizational commitment, as well as organizational commitment and job satisfaction. The mediating effect of organizational commitment and the moderating effect of self-efficacy also had a positive effect. The implication of this study is that the perception of corporate CSV activity plays a crucial role in the current service landscape. Therefore, it is recommended that companies conduct a range of CSV activities and create an inclusive system and organizational culture that encourages active participation of non-permanent employees.

This study is about the impersonal behavior of the supervisor, which is the root cause of 'Workplace Harassment [bullying]', which becomes familiar to Korean workers. For the purpose of the study, characteristics of supervisors are classified into three situations such as personal situation (authoritarian propensity), organizational situation (job insecurity), and personal and organizational situation (self-defensive ambivalence). Then the effects of those propensities on the organizational commitment of their subordinating workers through abusive supervision were analyzed. To this end, separate surveys for team leader and team members were composed. The subjects were male and female workers in large enterprise in Korea. The major results of the study are as follows. First, the three predisposing factors related to the abusive supervision (authoritarianism, job insecurity, and self-defensive ambivalence) made positive (+) effects on the abusive supervision of the supervisor. Second, in the hypothesis 2 regarding the effects of the abusive supervision of the supervisor on the organizational commitment of the subordinates, it was found that the abusive supervision of the supervisor made negative (-) effects on the organizational commitment of the subordinates. Third, in the verification of the hypothesis 3 regarding the mediating effect of the abusive supervision, the three predisposing factors partially mediated the abusive supervision and made negative (-) effects on the organizational commitment of the subordinates.

허파에 대한 수소 자기공명영상은 현재까지 거의 불가능한 것으로 알려져 있다. 허파의 조직과 비어있는 공간 사이의 심한 자화율(susceptibility) 차이로 인해서 영상왜곡 현상이 유발되어 그릇된 영상정보를 만들기 때문이다. 본 강좌에서는 이러한 문제를 해결할 수 있는 레이저 광펌핑 방법으로 초편극화된 비활성기체를 이용한 자기공명연구를 소개한다. 일반적인 자기공명 신호와 쳐편극화된 비활성기체를 이용한 자기공명 연구를 소개한다. 일반적인 자기공명 신호와 초편극화 기체를 이용한 신호의 차이와 물리적인 원리를 고찰할 것이다 . 비활성기체가 초편극화 되었을 때, 일반적인 자기공명의 경우에 (자기장: 1 Tesla, 온도는 $30^{\circ}C$의 열평형상태) 비해서 약 $10^{5}$ 정도의 magnetizaion 향상을 기대할 수 있으며, 기체상태라는 점이 감안된다 해도 의미 있는 자기공명신호를 획득할 수 있다. 비활성기체를 초편exchange 방법을 통하여 간접적으로 가스를 편극화 시키는 두 가지 방법이 있다. 이들의 기본적인 원리와 두 방법의 장단점 등을 알아 볼 것이다. 더불어, 초편극화 정도가 외부자기장의 세기 차이에 의한 영향을 받지 않는 다는 특성을 이용하는 경우, 비용을 최소화 하면서 고해상도의 영상을 얻을 수 있으며, 이동성이 용이한 낮은 자기고명진단기가 가능한데 이에 대한 소개를 할 것이다. 그리고, 초편극화가스를 이용한 자기공명영상 연구의 현재 동향 및 미래에 대해서 논의한다.

방사선치료에서 결손조직의 보호를 위해 사용되는 기존의 결손조직 보상체는 체표윤곽을 얻기위해 컴퓨터단층촬영영상이나 자기공명촬영영상등의 의료영상을 이용해 왔다. 하지만 이러한 촬영을 위해서는 고가의 비용이 소요되고 방사선치료에 따른 체표윤곽의 변화에 적절히 대응하지 못하는 등의 단점이 지적되고 있다. 따라서 본 연구에서는 사용이 간편한 디지털 카메라로 환자를 촬영한 후 얻은 2차원 이미지를 이용하여 결손조직 보상체를 제작하고 이의 유용성 평가를 위해 기하학적, 선량학적 평가를 수행하였다. 그 결과, 조직결손을 보정하고 정상조직을 보호할 수 있어 임상적용의 가능성을 확인 할 수 있었다.
