This study examined the effects of a 4 week, 8 session LCSI programs on the self-efficacy, adjustment to college of undergraduates. The number of participants was 39 students at one region. For statistical analysis, descriptive statistics, paired t-test, and Pearson correlation were used with SPSS WIN 18.0. The results are summarized as follows. The self-efficacy and underlying factors of self-efficacy in self-confidence, sense of self-regulated, task difficulty increased significantly, and the underlying factors of adjustment to college life academically, socially, emotionally, physically, love of the university, and adjustment to college increased significantly. Therefore, the self-growth program using LCSI, self-efficacy and adjustment to college life appears to have significant effects, and the LCSI program is more useful to consider the characteristics of each person by applying a range of situations to plan and deliver, such as communication or subjects, and conflict management in a variety of situations.

A active magnetic sensor has been widely used in the underwater guided weapon system because it is able to detect a target accurately in close range, but the target doesn't have any good countermeasure to overcome the threat from the active magnetic sensor. Recently, in order to increase the damage area of target by shock wave with explosion of the underwater weapon system and to detect small target, the maximum target detection range of the active magnetic sensor needs to be increased. One method for improving maximum target detection range is to improve output power from transmitter through demagnetization factor minimization of a transmitting core. Thus, in this paper, we describe the study results on the transmitter core shape design to enhance output power of the active magnetic sensor.

The present study conducted in two parts toward employees in government office and state-owned companies, and financial companies. First, main impacts were demonstrated in the links between superior communication ability (SCA) and outcome variables (self-efficacy, and learning goal orientation). Second, mediating effects of self-efficacy and LGO were investigated in the relation SCA-Innovative behavior. The data which applied in analysis was collected from 318 employees who work at government office and state-owned companies, and financial companies in Jeju island. The results were as follows. First, SCA were positively associated with self-efficacy and LGO. Second, self-efficacy and LGO were fully mediated both relationships between SCA and innovative behavior. Findings were as follows. SCA is an important factor on self-efficacy and LGO. Such the results have meaningful implications in the research area of communication. The importance of self-efficacy and LGO were demonstrated when considering the both variable in the relations SCA-innovative behavior.

The purpose of this study is to find the relation between the detailed categories of the self-efficacy of workers in the field of railroad signaling and the detailed categories of their fatigue in the use of analysis of moment structure(AMOS) model. A self-administered questionnaire survey of workers in the field of railroad signaling had been conducted and a total of 341 copies were analyzed. This study had the assumption that their general self-efficacy and social self-efficacy would negatively influence their physical fatigue and mental fatigue. As a result, their general self-efficacy negatively influenced their physical fatigue and mental fatigue, whereas their social self-efficacy didn't influence their physical fatigue and mental fatigue. Therefore, it is possible to reduce the fatigue of the study subjects by enhancing corporate support to increase their general self-efficacy.

The purpose of this study is to investigate the relationships between self-leadership(rehearsal, self-goal setting, self-respect) and empowerment, self-efficacy and innovation. In order to verify the relationships, data obtained from 305 employees working in Seoul were analyzed by using SPSS 18.0 and AMOS 8.0. This study reports findings as follows: First, the relationship between the self-leadership(rehearsal, self-respect) and the empowerment is positively related. Second, there was also a positive correlation between the self -leadership(rehearsal, self-goal setting, self-respect) and the self-efficacy. Third, the empowerment is positively related with innovation, however self-efficacy has no correlation with innovation. Implications of these results for research and practice were discussed.

The purpose of this study was to examine the effect of decentering and self-silencing in a relationship between socially prescribed perfectionism and social anxiety. We predicted self-silencing would function as a mediator in this relationship, and that decentering would moderate this mediation effect. To investigate this aim, three hundred seven university students were surveyed. All variables showed statistically significant correlations, and there was no statistically significant difference in the moderating effect of decentering in the relationship between socially prescribed perfectionism and social anxiety. Conversely, this study showed that there was a significant difference in the moderating effect of decentering in the relationship between self-silencing and social anxiety. In addition, socially prescribed perfectionism affected social anxiety through self-silencing, and decentering moderated the mediating effect of self-silencing. Implications and potential follow-up studies are discussed.

The purpose of present study is to investigate what is the most important factor among personality, social relation perception, and cultural influence on North Korean Defectors' self-enhancement bias, and how their self-enhancement bias influences on their psychological adaptation in South Korea. To implement this, we compared the self-enhancement bias of South Korean undergraduates and North Korean Defector undergraduates, and social desirability, too. However, there was no significant result. Based on this outcome, we focused on 121 North Korean Defectors' self-enhancement bias mechanism. We found that personality and social relation perception factors influenced significantly on their self- enhancement bias and furthermore their self-enhancement bias affected on their psychological adaptation. In addition to this, we identified sex difference at this mechanism. That is, women showed the same pattern with the existing findings in the study of self-enhancement bias mechanism, but men showed somewhat different pattern.

This study is on the effects of lifelong education participative motivation, self-efficacy, and self-directed learning on subjective happiness of middle age adults. Middle age adults 40-64 years old are questionnaire survey target in Incheon and Gyeonggido and total 289 copies among 300 were analyzed through SPSS 21.0. The major findings of this study con be seen as follows: The variables more affected on educational satisfaction of middle age adults are goal-oriented motivation and activity-oriented motivation in lifelong education participative motivation, self-regulated efficacy in self-efficacy, and each personality, recognition and environment in self-directed learning. In conclusion, new paradigm is needed for middle age adults in lifelong learning society. This program should provide them with knowledge and information for adapting the future society, Furthermore, middle age adults can achieve their own self exploration, self-development and self-realization through the lifelong education program. Given a chance of lifelong education, middle age adults should be provided with the specific programs.

본 논문에서 생체실험용 대형 2축 자기장 발생장치를 설계하였다. 생체실험 대상이 유동적이지 않고 홀더(holder)내에 고정될 경우 이는 방향성(orientation)의 논란이 불가피하며 이 영향을 줄이기 위해 각 축에 4개씩 총 8개의 코일을 사용하여 2축 4중코일 구조로 장치를 설계하였다. 원하는 특정 자기장에 대한 권선수 및 전류치를 결정하기 위해 정육면체 구조의 자기장 발생장치를 원통형으로 근사화시켜 간소하게 수식을 유도하였으며 각 코일의 최적위치 및 최적 권선비는 별도의 최적화 시뮬레이션을 통하여 수치를 추출하였다. 이렇게 얻어진 수치들을 MATLAB으로 제작한 시뮬레이터에 적용하여 설계 조건과 동일하게 모델링한 발생장치 주변에서의 자기장 분포를 시뮬레이션 해보았으며, 각 축에서의 균일도를 평가하여 균인 자기장 분포영역 또는 사용가능영역을 도출하였다. 장치해석 결과, 임의의 기준 자기장에 대해 약 5%의 오차범위를 인정할 경우, 최소 60% 이상의 사용가능영역을 확보할 수 있었으며, 이 영역 내에서는 고도의 균일 자기장이 분포함을 확인할 수 있었다.
