Universities have recently introduced problem-based learning (PBL) to various subjects to enhance problem-solving skills (including self-directed learning and small-group learning) required in industry. The PBL module was applied to the personal production process in a draping class. A study was based on a questionnaire after conducting two PBL modules with a group of students. Each PBL module included ‘design analysis’, ‘presentation of flat sketch and draping plan’, ‘discussion of the plan’, ‘evaluation of the draping result and correcting the problem’, and ‘final evaluation of the completed project’. Results showed that satisfaction with the PBL method and its activities was higher than satisfaction with existing teaching methods. In particular, among the various components, the ‘design analysis’ and ‘the presentation step of flat sketch and draping plan’ stages were more helpful to students compared to small-group discussion. Moreover, the effects of PBL were observed through student reflection essays, in which students suggested that PBL was very effective in enhancing problem-solving through self-directed and small-group learning. Despite the overall satisfaction with PBL, students expressed some minor difficulties associated with awkwardness with a novel learning method, lack of diverse perspectives among each group, and poor communication skills. Therefore, the study shows that PBL is highly likely to be useful to students when they are solving pattern drafting problems and making samples through self-directed learning and small-group learning.

Due to the COVID-19 pandemic situation, online education has emerged as an important research field to match its growing necessity. In this vein, this research explores one of the challenges facing online teaching of the Arabic language to Korean students at the university level based on the practical experience of online teaching in the academic year of 2020 while focusing on the role of students. The main goal of this research is to give some answers to its main question, which is: How is it possible to activate the role of students in the online classes of the Arabic language? The study suggests some online activities through which the role of students in online classes can be activated. An online survey questionnaire was provided to test the influence of some of those activities and to explore the students’ feedback. Additionally, interviews were conducted with some students to gain further understanding of their opinions about those activities. The results of the study showed positive feedback from the students towards those activities and provided some advantages of using those online activities for adding enjoyment to the students’ assignments. It is also recommended that teachers include more innovative online activities which match their students’ needs.

During the shift from gasoline vehicles to electric ones, auto parts manufacturing companies have realized the importance of improvement in the manufacturing process that does not require any layout changes nor extra investments, while maintaining their current production rate. Due to these reasons, for the auto part manufacturing company, I-company, this study has developed the simulation model of the PUSH system to conduct a process analysis in terms of production rate, WIP level, and logistics work’s utilization rate. In addition, this study compares the PUSH system with other three manufacturing systems -KANBAN, DBR, and CONWIP- to compare the performance of these production systems, while satisfying the company’s target production rate. With respect to lead-time, the simulation results show that the improvement of 77.90% for the KANBAN system, 40.39% for the CONWIP system, and 69.81% for the DBR system compared to the PUSH system. In addition, with respect to WIP level, the experimental results demonstrate that the improvement of 77.91% for the KANBAN system, 40.41% for the CONWIP system, and 69.82% for the DBR system compared to the PUSH system. Since the KANBAN system has the largest impacts on the reduction of the lead-time and WIP level compared to other production systems, this study recommends the KANBAN system as the proper manufacturing system of the target company. This study also shows that the proper size of moving units is four and the priority allocation of bottleneck process methods improves the target company’s WIP and lead-time. Based on the results of this study, the adoption of the KANBAN system will significantly improve the production process of the target company in terms of lead-time and WIP level.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization’s safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

Smart factories can be defined as intelligent factories that produce products through IoT-based data. In order to build and operate a smart factory, various new technologies such as CPS, IoT, Big Data, and AI are to be introduced and utilized, while the implementation of a MES system that accurately and quickly collects equipment data and production performance is as important as those new technologies. First of all, it is very essential to build a smart factory appropriate to the current status of the company. In this study, what are the essential prerequisite factors for successfully implementing a smart factory was investigated. A case study has been carried out to illustrate the effect of implementing ERP and MES, and to examine the extensibilities into a smart factory. ERP and MES as an integrated manufacturing information system do not imply a smart factory, however, it has been confirmed that ERP and MES are necessary conditions among many factors for developing into a smart factory. Therefore, the stepwise implementation of intelligent MES through the expansion of MES function was suggested. An intelligent MES that is capable of making various decisions has been investigated as a prototyping system by applying data mining techniques and big data analysis. In the end, in order for small and medium enterprises to implement a low-cost, high-efficiency smart factory, the level and goal of the smart factory must be clearly defined, and the transition to ERP and MES-based intelligent factories could be a potential alternative.

This paper presented a case of the ICT Innovation Centres in Primary Schools in Kenya for the effective operation and management of ICT integrated education based on the results of the centre users’satisfaction and improved competency in ICT in education. Global society pursed results-based management to materialize the principles of effective development cooperation. In line with the principle, the project team for establishing the Centres has supported the local operators to operate and manage the centres with the manual and surveyed to capture the results of the operation and management focusing on the users' satisfaction and competency. As result, these two centres encouraged the users to be exposed to use facilities and equipment for understanding ICT and applying it in their teaching and learning activities physically. In particular, these centres helped them to participate in community activities which were recognized as the foundation of sustainable operation and management of the centres. The teaching and learning environment significantly affected the users' satisfaction and improved competency. But, still, additional content would be required for enhancing the performance of the users. For the long-term results, this study proposed that the impact of using the centres should be monitored continuously to carry out tangible results of teaching and learning performance because the centres were operated less than a year and still required to stock relevant data.

With the rise of the 4th Industrial Revolution, a paradigm shift is being demanded across society, and this change is seen in the rapid increase of learners who want online classes that can be taken relatively freely compared to traditional classes that are constrained by time and space. Cyber university’s learning method using an online platform has the advantage of overcoming the limitations of teaching-learning methods and university education in a limited space, and providing educational opportunities to people who need education anytime, anywhere. However, in cyber universities, issues have also been raised about the stability of the educational system, the quality of educational contents, and the appropriateness of educational services. Thus, in order to maximize the learning effect in cyber universities, a system that supports and manages learning participation activities of learners is required so that not only high-quality contents but also various interactions in the teaching-learning process are activated. In this thesis, based on the author’s own experience in subject development and operation, I would like to examine the effects that the interaction between instructor-tutor-learners through the role of a subject-dedicated tutor and the teaching-learning method using an online platform.

본고는 2015 개정 교육과정에서 추구하는 창의융합형 인재 양성을 목표로 하여 진행된 연계⋅융합 수업의 한문과 수업 실천 사례이다. 평소 연계⋅융합 수업에서 배제되거나 도구적 역할에 머물렀던 한문과의 연계⋅융합 수업의 가능성을 확인하기 위하여 실험적으로 시도된 것이다. 자칫 특정 교과에 치우친 주제로 인식될 수 있는 민주시민교육이라는 영역에서 ‘민주주의와 참여’라는 주제로 한국사⋅통합사회 교과와 함께 연계⋅융합 수업을 진행하였다. 민주시민교육에서 추구하는 민주시민으로서의 자질과 역량을 한문과 인성역량과 연결하여 수업의 목표로 삼고, ‘한문과 인성’ 영역의 성취기준에 맞추어 과정형평가가 이루어질 수 있는 수업으로 설계하였다. 과정형평가의 수행과 분절된 교육활동을 하나로 연결하기 위해 ‘교육과정-수업-평가- 기록’을 일체화하여 수업을 진행하였다. 이는 수업의 중심을 교사에서 학생으로 이동시켜 학생들이 삶의 주체로 성장할 수 있게 돕기 위한 것이다.

코로나19는 선원교대를 지연시키면서 선박과 선원의 안전에 위협을 가하고 있다. 선원의 승선환경에 있어 해운기업과 정부가 놓치고 있는 사각지대는 존재하고 있다. 선원의 안전을 위협하는 비상체제 상황에서 인적사고를 유발할 가능성을 제거하기 위해 효과적인 교대방안을 구상해볼 필요가 있다. 본 연구에서는 전직 및 현직 선원을 대상으로 설문조사를 진행한 결과, 승선생활에서 가장 중요하게 생각하는 요인은 안전이었으며 비상체제 상황에서 가장 필요한 것은 임금 및 복지의 향상보다 선원의 원활한 교대방안이 우선적으로 확보되어야 한다고 응답하였다. 국적해운기업의 대륙별 주요 항로를 분석하여 기항 횟수가 많고 항공연계성지수가 높은 항만을 거점항만으로 선정하였다. 또한, 국제해운에 승선하는 국내 선원의 효과적인 교대를 위한 이동경로를 구상하였다. 그를 위해 비상 시 선원의 안전한 본국 귀환 및 이송을 위하여 선박과 항만, 항공을 연계한 이동경로 구축은 다른 나라와의 협의가 필수적이다. 또한, 국제해사기구의 협 력을 통해 선원교대의 어려움에 처해있는 선원들을 위해 함께 노력할 필요가 있다. 이를 시작으로 국적 선원이 승선하는 정기선과 부정 기선의 귀항로 및 불귀항로 정보와 선원 수에 대한 모니터링 체계를 갖추어 상시 확인할 수 있어야 한다. 그러한 체계가 갖추어진다면 비상체제 발생 시 우리나라의 정책 대응방향을 보다 빠르게 결정할 수 있을 것이다. 선원들의 처우를 개선하기 위한 해운기업의 노력과 더 불어 개정이 필요한 국내법을 검토하고 선원에 대한 인식을 개선하기 위한 국민적·사회적 관심이 필요할 것이다.
