Recently the importance of emotional labor has increased so this study aims to prove the effects of emotional labor(surface acting and deep acting) on counterproductive work behaviors(deviate from organization and individual deviation) using burnout(emotional exhaustion, personality disorder, decrease in sense of accomplishment) as a medium. 350 surveys were sent to employees such as workers from call centers, salesperson from department store, financial worker, hospital staff, flight attendant and workers from customer center who and worked with emotional labor and 300 surveys excluding insincere ones were used for analysis. The result is as follows. First, surface acting which is a type of emotional labor chosen by customer workers had a positive effect on burnout such as personality disorder and decrease in sense of accomplishment. Second, deep acting had a negative effect on personality disorder and decrease in sense of accomplishment but did not show any effect on emotional exhaustion. Third, personality disorder and decrease in sense of accomplishment among burnout had effect on counterproductive work behaviors(deviate from organization, individual deviation) but emotional exhaustion did not show any effect on work behaviors(deviate from organization, individual deviation). Based on the result of analysis, implication of this study and direction of future research were suggested.

It is expected that expanded use of smartphone and enhanced information technology will enable smartwork to change individuals and organizations. Smartwork is expected to allow people to perform their roles without barriers of time and space. However, people tend not to accept and actively utilize smartwork. The present study is to examine how important flexibility-willingness is for performance outcome in the context of smartwork. It was hypothesized that flexibility-willingness mediates between perceived smartwork usefulness and work-family conflict. It was also hypothesized based on technology acceptance model that task interdependence and process control moderates the relationship between flexibility-willingness and work-family conflict because the relationship is not consistent. The results show that the mediation effect of the flexibility-willingness is statistically significant. The moderator effects of task interdependence was marginal proved but process control wasn't. From these results, we discussed the theoretical implications of findings, limitations, suggestions for future research in discussion.

This study inquired following research questions by a narrative research method : What was the job of an engineer in mechanical design field? How did he fulfill his job-related learning in his workplace? What were the context and the characteristic of the job-related learning in the workplace? And some implications of the job-related learning on engineering education were discussed. We identified that the research participant's career as a mechanical engineer has developed through three stages. At first, he engaged on conceptual design of a semi-conductor test machine through self-initiated learning from basic to whole system of the machine. At second stage, he leaded a design group for the concrete design of a ball type semi-conductor test machine. In this stage he learned the meaning of cooperation and cooperative learning. At third stage, he initiated to found an entrepreneur company that was specified to design a semi-conductor test machine. He became CEO of the company. He learned the R & D policy making through contacts with global company, visiting exhibition in abroad. Eventually his main task as a mechanical engineer was the problem solving in the process of machine design. He had experienced and learned through his works : project management, independent fulfilling of tasks, functional analysis and reverse engineering, conceptualizing and test, cohesive cooperation, dialogue and discussion, mediation of conflict, human relationship, leadership. The implication of the narrative analysis on engineering education is, proposed, to give the students more chances to experience and to learn such activities.

This study aims to explore information seeking behavior of natural scientists when they are writing a research proposal for applying to funding. It focuses on understanding their information needs and information seeking behavior, and factors influencing the behavior. Based on the conceptual framework of task-based information seeking, qualitative research methods including in-depth interviews and diary study are used. The results reveal that a variety of communicative subtasks take place in the process of research proposal writing. Also, the scientists tend to need information related funding opportunities and to research design, and access sources including human resources, documents, online databases and websites to meet their information needs. Finally, the study shows that the scientists' information seeking behavior when writing a proposal is influenced by personal, task-related, and sociocultural factors. This study will be helpful to design effective information services and strategies to assist science scholars applying to research funding.

ReLU(Rectified Linear Unit) 함수는 제안된 이후로 대부분의 깊은 인공신경망 모델들에서 표준 활성함수로써 지배적으로 사용되었다. 이후에 ReLU 를 대체하기 위해 Leaky ReLU, Swish, Mish 활성함수가 제시되었는데, 이들은 영상 분류 과업에서 기존 ReLU 함수 보다 향상된 성능을 보였다. 따라서 초해상화(Super Resolution) 과업에서도 ReLU 를 다른 활성함수들로 대체하여 성능 향상을 얻을 수 있는지 실험해볼 필요성을 느꼈다. 본 연구에서는 초해상화 과업에서 안정적인 성능을 보이는 EDSR(Enhanced Deep Super-Resolution Network) 모델의 활성함수들을 변경하면서 성능을 비교하였다. 결과적으로 EDSR 의 활성함수를 변경하면서 진행한 실험에서 해상도를 2 배로 변환하는 경우, 기존 활성함수인 ReLU 가 실험에 사용된 다른 활성함수들 보다 비슷하거나 높은 성능을 보였다. 하지만 해상도를 4 배로 변환하는 경우에서는 Leaky ReLU 와 Swish 함수가 기존 ReLU 함수대비 다소 향상된 성능을 보임을 확인하였다. 구체적으로 Leaky ReLU 를 사용했을 때 기존 ReLU 보다 영상의 품질을 정량적으로 평가할 수 있는 PSNR 과 SSIM 평가지표가 평균 0.06%, 0.05%, Swish 를 사용했을 때는 평균 0.06%, 0.03%의 성능 향상을 확인할 수 있었다. 4 배의 해상도를 높이는 초해상화의 경우, Leaky ReLU 와 Swish 가 ReLU 대비 향상된 성능을 보였기 때문에 향후 연구에서는 다른 초해상화 모델에서도 성능 향상을 위해 활성함수를 Leaky ReLU 나 Swish 로 대체하는 비교실험을 수행하는 것도 필요하다고 판단된다.
