Facial expression recognition plays a significant role in understanding human emotional states. With the advancement of AI and computer vision technologies, extensive research has been conducted in various fields, including improving customer service, medical diagnosis, and assessing learners' understanding in education. In this study, we develop a model that can infer emotions in real-time from a webcam using transfer learning with TensorFlow.js and MobileNet. While existing studies focus on achieving high accuracy using deep learning models, these models often require substantial resources due to their complex structure and computational demands. Consequently, there is a growing interest in developing lightweight deep learning models and transfer learning methods for restricted environments such as web browsers and edge devices. By employing MobileNet as the base model and performing transfer learning, our study develops a deep learning transfer model utilizing JavaScript-based TensorFlow.js, which can predict emotions in real-time using facial input from a webcam. This transfer model provides a foundation for implementing facial expression recognition in resource-constrained environments such as web and mobile applications, enabling its application in various industries.

Recent demands from construction industry have emphasized the capability for graduates to have improved skills both technical and non-technical such as problem solving, interpersonal communication. To satisfy these demands, problem-based learning that is an instructional method characterized by the use of real world problem has been adopted and has proven its effectiveness various disciplines. However, in spite of the importance of field senses and dealing with real problem, construction engineering education has generally focused on traditional lecture-oriented course. In order to improve limitations of current construction education and to satisfy recent demands from construction industry, this paper proposes a new educational approach that is Failure-Based Learning for using combination of the procedural characteristics of the problem-based learning theory in construction technology education utilizing failure information that has the educational value in the construction area by reinterpreting characteristics of construction industry and construction failure information. The major results of this study are summarized as follows. 1) Educational effect of problem-based learning methodology and limitation of application in construction area 2) The educational value of the information on construction failure and limitation in application of the information in construction sector 3) Anticipated effect from application of the failure-based learning 4) Development and application of the failure-based learning model

This research aims to produce and implement web-based continuing nurse education programs in response to nurses' educational needs, and to verify them, thus preparing for the times that the program will be offered via web. This research designed, produced and implemented 'emergency nursing' and 'medical fee schedule management' subjects based on Jung, In-seong's(1997) web-based instructional system design, and then compared the learning achievements of web-based learning group of 38 people with those of face-to-face learning group of 39 people. The questionnaire have been developed by these researchers to measure pre-learning knowledge on 'emergency nursing' and 'medical fee schedule management.' Data collected for this research have been given statistical analysis, using SPSS 10.0 for Windows Program. As a result of giving Mann-Whitney test, with respect to pre-learning prior knowledge level, there was no significant difference between the web-based learning group and the face-to-face learning group(Z=-.092, p=.926), while after completing learning, there was a significant difference in the learning achievements between the web-based learning group and the face-to-face learning group(Z=-2.406, p=.008). That is, this research revealed this: the web-based learning group and the face-to face learning group with both having no significant difference in the pre-learning level, after receiving the continuing education each with different methods(face-to-face education and web-based education), showed that the web-based learning groups attained higher learning achievements than the face-to-face learning groups. This result proves the effect of the web-based education to be no worse or even better than that of the face-to-face education, provided that choices of appropriate themes and quality courses composition, as well as systematic design development effective implementation are guaranteed.

This study was planned to investigate the relationship between development levels of learning organization and organization effectiveness in Hospital. Data were collected from 285 respondents who have participated in 'Learning Organization Project'(response rate =$50.5\%$). Structured questionnaire were applied by self administrated survey for two weeks since 2003 May. Main results were as follows; In the result of factor analysis, four factor were created and almost questionnaire items were classified into as same categories as theoretical concepts. Cronbach's a coefficient also showed over 0.7 in all categories. This result means that measurement tool to evaluate the development level of learning organization is valid and reliable. In the comparison of the development level of learning organization by participants' specialties, managerial workers perceived the lowest construction level, while medical technicians evaluated it as the highest level. In regression analysis, the perception levels of work environment, task and human aspect showed positive relationship with job competency significantly. For job satisfaction, levels of task and human aspects had positive relationship significantly. In addition, for organizational commitement, levels of organization and human aspect were positive predictors. Finally, for the satisfaction about experience of learning organization project, levels of environment, task and hmm aspects were related positively. We concluded from these result that the positive relationship between construction levels of learning organization and organization effectiveness was extended to hospital, besides industrial fields. We recommend the introduction and facilitation of learning organization project in various settings to improve the competency of knowledge management in individual and organizational levels.

Purpose - this study analyzes the impact of restaurant startup education on transfer effects in learning and entrepreneurial intentions based on previous research. Also, problems and ways to provide effective business startup education for a restaurant founder will be proposed based on the result. Research design, data, methodolog - this study collected surveys by conducting direct investigation. From July 20th of 2016 to September 20th of 2016 (approximately 60 days), the survey was collected. Out of 540 surveys, 520 were collected. And excepting 9 surveys which were untrustworthily conducted, total 511 surveys were used for the analysis. Results - First, as a result of the impact of which factor of a restaurant founder's startup education has a positive impact on transfer effect in learning (the satisfaction of startup education and learning transfer), law education, entrepreneurship education and business district analysis education and practical education have turned out be positively related variables. Secondly, as a result of the impact of a restaurant founder's startup education satisfaction on transfer in learning, it has been identified that startup education has a positive impact. Lastly, by conducting an analysis to find out which factor from a restaurant founder's transfer effect in learning has an impact on entrepreneurial intention, all variables, including startup education satisfaction and transfer effect in learning, are positively influencing factors. Conclusions - as startup education satisfaction of a restaurant founder is increasing, there is a higher level of transfer effect in learning. Moreover, as transfer effect of startup business is getting higher, it has an impact on entrepreneurial intention.

본 연구는 기업에서 CEO의 내 외부 활동(정보, 지식경영, 학습조직)이 혁신활동(활용적, 탐색적)과 경영성과에 미치는 영향을 알아보기 위하여 국내 기업의 CEO 300명을 대상으로 설문조사를 토대로 통계분석을 하였다. 분석 결과 정보와 학습조직 활동은 활용적 혁신활동과 탐색적 혁신활동에 유의한 정(+)의 영향을 미치는 것으로 나타났으나, 지식경영 활동은 탐색적 혁신활동에서 통계적으로 유의미한 영향을 끼치지 못하였다. 또한, CEO 내 외부 활동에서 정보, 지식경영, 학습조직 활동의 영향을 받은 활용적, 탐색적 혁신활동은 기업의 경영성과에 유의한 정(+)의 영향을 미쳤으나 영향력의 세기는 차이를 보였다. 따라서 기업의 경영에서 CEO의 내 외부 활동 중에서 정보, 지식경영, 학습조직 활동에 의한 활용적 혁신과 탐색적 혁신활동 발현으로 경영성과를 극대화시키기 위한 모색은 선행 연구에서 지각된 활동을 기반으로 하여 기업의 경영 환경을 고려하여 유리한 활동을 추출하고 이를 경영 전략에 반영하는 것이 기업에서 최상의 경영성과 목표달성에 유리함을 본 연구결과에서 시사하고 있다.
