As the level of people's demand for service quality provided by public institutions increases, interest in improving organizational effectiveness of internal members is increasing. In this context, this study aims to identify the predisposing factors affecting the job satisfaction and perceived job performance of public institution members. In this study, public service motivation, work autonomy, and person-system fit were presented as antecedents to verify the organizational effectiveness, and the results were tested by regression analysis. As a result, all three antecedents have significant effects on job satisfaction and perceived job performance. Public service motivation, work autonomy has a relatively higher impact on job satisfaction. On the other hand, person-system fit has a relatively higher influence on perceived job performance. In particular, the results of this study confirmed that PSM theory is consistent with the main trends and is significant in organizations created through artificial integration. This result suggests the need to maintain the effectiveness of the public organization in the future due to the change of integration of public organizations.

This study is to verify relative influence of individual, parent, peer, teacher-related variables as protective factors and risk factors of academic hatred. Surveys were conducted with 1,015 (women, 57.3%) high school third grade students across eight schools where are located in Seoul, Incheon, and Geyonggi province. Correlation analysis and hierarchical multiple regression analysis were performed. The findings are summarized as follows. Teacher's academic pressure did not have significant correlation with student's basic psychological needs, teacher's autonomy support, teacher's support, and peer support whereas other variables showed significant correlation each others. The hierarchical multiple regression analysis indicated that student's individual competence and autonomy, parent's academic support, and teacher's emotional support work as protective factors and that parent's academic pressure functions as a risk factor. The effects of peer support disappeared when teacher-related factors were included. In addition, the effects of teacher's autonomy support disappeared, while the effects of teacher's support strengthened when learner's basic psychological needs were input. This study is meaningful in that it clarified academic hatred which had not been studied in other research and that it provided theoretical foundation for subsequent studies on academic hatred by examining relative influence of related variables. Lastly, it presented its limitation, implications on intervening strategies in school counseling, and suggestions for later studies.

With the recent development of AI and ICT, autonomous vehicles are becoming a reality, and sales of the vehicles equipped with partial autonomous driving technology are also rapidly expanding. In this situation, technology research on autonomous vehicles has been actively conducted, but research on exploring the perception of autonomous vehicles from the user's perspective is relatively insufficient. Therefore, this study categorizes autonomous vehicle users into four types - , , , and . Then, it examines the characteristics of each type. For this purpose, we applied Q-methodology, a qualitative research method, to observe self-referent subjectivity of 32 P-samples using a Q-sample which consists of 34 statements. The results of our study have significance in that they provide domestic and global automakers with strategic directions for technological development and market expansion of autonomous vehicles, and academically provide hypotheses for subsequent quantitative research.

The purpose of this research is to provide implication for the preparation of the specific and practical strategy through an analysis of whether commitment to career choice (vocational exploration commitment and tendency to foreclose) acts as a mediating effect between self-determination (autonomy, competence, and relatedness) and career preparation behavior. Data was collected from 258 students at a vocational training school in Seoul, and was analyzed hierarchical regression analysis. The result shows that commitment to career choice has partial mediating effect on the relationship between self-determination and career preparation behavior. Secondly, self-determination effects on career preparation behavior and among them, the effect of relatedness is predominant. The result of this study suggest practical insights about how a vocational training school can motivate students to participate in self-determination and commitment to career choice for improved educational environment with related career preparation programs.

목적 : 양심안영(養心安營), 청신녕지(淸神寧志), 조리기혈(調理氣血)의 효능을 가진 심유혈(心兪穴)($BL_{15}$)이 자율신경의 안정에 기여할 수 있다는 것을 입증하기 위하여 객관적으로 자율신경의 활성과 심장의 많은 연관성이 있다고 알려진 HRV(Heart Rate Variability)를 이용하였다. 방법 : 안정을 취한 후 29명의 남자 대상자를 HRV가 먼저 측정하였다. HRV 측정 후 대상자의 량측(兩側) 심유혈(心兪穴)에 자침하고 전침으로 지속적인 자극을 주었으며, 15분간 이 상태로 류침(留鍼)하였다. 발침(拔鍼) 후 다시 HRV를 측정하여 이를 측정 전과 비교하였다. 측정 결과의 비교 항목은 MHRT, SDNN, RMSSD, TP, VLF, LF, HF, Norm LF, Norm HF, LF/HF ratio로 하였다. 결과 : MHRT는 유의성이 있었다. SDNN은 유의성이 없었다. RMSSD는 증가하였으나, 유의성이 없었다. TP는 감소하였으나, 유의성이 없었다. VLF는 감소하였으나, 유의성이 없었다. LF는 감소하였으나, 유의성이 없었다. HF는 증가하였으나, 유의성은 없었다. Norm LF는 감소하였으나, 유의성이 없었다. Norm HF는 증가하였으나, 유의성은 없었다. LF/HF ratio는 감소하였으나, 유의성이 없었다. 결론 : 심유혈(心兪穴) 자침 결과는 교감 신경의 흥분을 가라앉히고 부교감 신경의 안정성을 증대하여, 심장의 안정도에 기여하는 것으로 보이나, 이는 통계적으로 의미가 없었다. 본 연구의 대상 집단이 소규모이며 스트레스가 아주 심하지 않은 집단이라는 점에서 유의성이 상대적으로 부각되지 못했다. 향후 비교할 만한 대조군을 설정하여 더 심한 스트레스를 받은 큰 집단을 대상으로 한 연구가 필요할 것으로 사료된다.

The questionnaires about the safety of the urban gas have been carried out for the end users. about 8 of 10 persons said that the urban gas Is safe to use, whereas $35\%$ of them said there exists a hazard of an accident in thier residences. There cannot be found the clear evidences that the understandings on the safety of the urban gas have no relations to their ages, sex, and monthly incomes, while the safety is less confidential to the highly educated, the accident-experienced, or the mans who are poor at the safety inspections. Most of the questioned man know the inspection knacks for the gas utilities, but only $60\%$ of them carry out it. They said that they do not feel the necessity of the inspection because they are inspected routinely by the suppliers or the inspection companies. This says that the end user does not concern the safety inspections, and in order to improve the dependency of the user for the self-inspections, the inspection staff should educate the user for the necessity and the knack of inspections to encourage the self-inspection of the gas utilities.

Since there is a limit to the physically visible horizon that sensors for autonomous driving can perceive, complementary utilization of digital map data such as a Local Dynamic Map (LDM) along the probable route of an Autonomous Vehicle (AV) is proposed for safe and efficient driving. Although the amount of digital map data may be insignificant compared to the amount of information collected from the sensors of an AV, efficient management of map data is inevitable for the efficient information processing of AVs. The objective of this study is to analyze the efficiency of information use and information processing time of AV according to the expansion of the active section of LDM-based static road and traffic information. To carry out this objective, a microscopic simulator model, VISSIM and VISSIM COM, was employed, and an area of about 9 km × 13 km was selected in the Busan Metropolitan Area, which includes heterogeneous traffic flows (i.e., uninterrupted and interrupted flows) as well as various road geometries. In addition, the LDM information used in AVs refers to the real high-definition map (HDM) built on the basis of ISO 22726-1. As a result of the analysis, as the electronic horizon area increases, while short links are intensively recognized on interrupted urban roads and the sum of link lengths increases as well, the number of recognized links is relatively small on uninterrupted traffic road but the sum of link lengths is large due to a small number of long links. Therefore, this study showed that an efficient range of electronic horizon for HDM data collection, processing, and management are set as 600 m on interrupted urban roads considering the 12 links corresponding to three downstream intersections and 700 m on uninterrupted traffic road associated with the 10 km sum of link lengths, respectively.
