The purpose of this study was to verify the impact of cognitive factors and GSR on the task performance. For this study 64 students participated. Multiple regression and repeated measures were applied to analyze the data. The result for the survey indicated that previous knowledge, physical efforts, and task difficulty had significant impacts on task performance. Particularly, task difficulty has a negative impact. This can be interpreted as someone who has high prior knowledge inputs higher physical efforts with low task difficulty perception will show high performance. On the other hand, the low arousal level of GSR in the evaluation stage is a prediction variable of task performance. This result shows that high prior knowledge and low arousal level of GSR produces high performance. However, the analysis of difference in GSR between learning and evaluation stages does not show significant difference. It suggests that physiological measure such as GSR is reliable index of cognitive load; however, it partially represents cognitive load. Other crucial factors should be added for comprehensive measures.

Requirement traceability should be continuously maintained in software development and evolution. However, it is usually updated in practice in the quality assurance phase. The gap between "is" and "should" exists due to the fact that developers must invest considerable effort to update requirement traceability while being able to obtain only marginal benefit from the updated traceability. To close this gap, we propose a spreadsheet application that enables developers to flexibly change mappings in a requirement traceability matrix. In this way, developers can reduce their effort in updating the requirement traceability matrix, but still obtain the common form of a requirement traceability matrix on a spreadsheet. The proposed application maintains the mappings between two artifacts on each sheet so that, whenever an artifact item changes, developers can instantly insert the relevant mapping changes. Then, when developers desire the common form of a requirement traceability matrix, the proposed application calculates the mappings among several artifacts and creates the matrix. The application also checks traceability errors and calculates the metrics so that developers can understand the completeness of the matrix. To understand the applicability of the proposed approach, we conducted a case study, which shows that the proposed application can be applied to the real project and easily incorporate the mapping changes.

This study examines whether the variables used in the Unified Theory of Acceptance and Use of Technology(performance expectancy, effort expectancy, social influence, and facilitating conditions) is applicable to continuous usage of uTradeHub at a time of expansion in the use of uTradeHub. In addition, the role of user satisfaction(mediating effect) and CEO support(interaction effect) in the relationship is identified attempting to provide basic data to help uTradeHub management strategy establishment. A total of 101 valid responses collected through questionnaires were used for empirical analysis(using SPSS 24.0), and the results are as follows. First, for the effect of the integration technology acceptance factor on user satisfaction(H1), only performance expectancy, effort expectancy, and social influence were significant, but facilitating conditions was not significant. Second, for the effect of user satisfaction on the continued use of uTradeHub(H2), there was a significant result. Third, the mediation effect on verification of user satisfaction(H3) was full where performance expectancy, effort expectancy, and social influence prompted continuous usage through user satisfaction. Fourth, for interactive effect verification of CEO support(H4), an interaction effect was shown only in the influence relationship of performance expectancy and social influence on user satisfaction.

The purpose of this study is to identify the cognitive and psychological precedence factors of career preparation behaviors of university students and to clarify the structural relationships between the variables. First, the effects of reflective learning on university students' career preparation behaviors were examined and the mediating effect of grit between reflective learning and career preparation behavior was verified. The research analyzed 307 university students in the 3rd and 4th year. The results of the study have shown that the reflective learning had a significant positive relationship with all variables of grit and career preparation behavior, but non-reflective learning have an insignificance relationship with all the main variables. In addition, reflective learning has a direct positive effect on career preparation behavior, and grit has a mediating effect on the relationship between reflective learning and career preparation behavior. The results of this study indicate that the more original variables are further identified and extended to improve career preparation behaviors of university students. It is significant that they are provided with the basic data for the development of career and job preparation education programs that can be applied in the university education field. In addition, it has been confirmed that it is important for university students to improve their ability to critically reflect on themselves, their surroundings and circumstances in order to keep them engaged and to maintain their interests. Moreover, higher education institutions should provide fundamental and extensible method of practice and educational environment.

This study utilized an analysis of teachers' use of smart devices in the class, which highlighted the impact factors, and elucidated the relationship between in fluencing factors. The Unified theory of Acceptance and Use of Technology (UTAUT) model is based on the study of extension and modification of the model proposed. For the study, a survey of 1,016 elementary school teachers in the Gangwon and Metropolitan(Seoul, Gyeonggi, Incheon) area was conducted. Was applied using the AMOS structural equation modeling analysis. The analysis examines the utilization of smart devices in class as factors affecting performance expectancy, effort expectancy of the main variables showed, Instant connectivity and Openness that has a direct impact on the performance expectations and effort expectancy.

지속적인 어업자원 이용에 대한 수산보조금의 역할을 분석한 기존 연구들은 단순히 세계 전체적이거나 국가별 총어업수입과 총어업비용만을 고려하여 잠정적으로 비용 절감형 또는 수입조장형 보조금이 어획노력량 수준을 증가시켜 어업자원의 감소를 부추기거나 남획을 초래했다고 결론짓고 있다. 또한 어업의 특성상 어업에 있어서 각종 규제수단이 사용되고 있음에도 불구하고 이들 수단들의 효과와 보조금과의 관계를 분석하지 못함으로써 어업자원에 대한 보조금의 영향을 명확하게 설명하지 못하였다. 본 연구에서는 어업에 있어서의 각종 규제수단의 사용에 따른 보조금의 영향을 국제적으로 권고되고 있는 생물경제모델을 이용하여 분석함으로써 보조금이 어업자원에 미치는 영향을 살펴보았다 분석결과에 따르면, 기존 연구들의 잠정적인 결론은 관리수단조치가 전혀 이루어지지 않거나, 이루어지더라도 불완전하게 어획노력량 등이 통제될 경우에만 타당한 것으로 나타났다. 반대로, 관리수단 하에서 어획노력량 등에 대한 감시 및 통제가 완벽하게 이루어질 경우에는 기존 연구결과와 달리 수산보조금이 어업자원에 부정적인 영향을 미치지 않는 것으로 분석되었다 오히려 일반적으로 부정적인 것으로 취급되는 보조금의 경우도 어업상황에 따라서는 어업자원에 대한 부정적인 피해 없이 어업에 긍정적인 영향을 줄 수 있는 것으로 나타났다.
