  • Prime movers in engine rooms inherently are much affected by the adjustment of their governors for the steady state and transient properties, consequently requiring that marine engineers shall be well familiar with the way to manage governor dials for normal operation. The hydro-mechanical governors basically have different control characteristics and adjustment parameters of stability from digital governors. The former include compensation mechanism using dash pot while the control algorithm of the latter is usually based on the PID action. This study is for configuring a simulation module to let trainees practice how to adjust dials for stability on hydraulic governors in the view that the practice by real governors and engines is time consuming and high cost for operation. The governor module includes the adjusting points such as speed set, speed droop, needle valve and compensation pointer with engine module of $2^{nd}$ order coupled. The results of simulation showed satisfactory responses as a training tool for the adjustment of control parameters.

  • This study is qualitative research with an aim of assessing experience of prospective social work student enrolled in social welfare field practice during COVID-19 pandemic. The results are shown below. First, the major negative answers of responders were the work-study imbalance of the student, the institution's concern for spread of infection, limited experience due to low-quality-of supervision, the difficulty on choosing institution, and worries on stop of practice due to the COVID-19 pandemic. Second, the key positive answers of responders were awareness of true meaning of social welfare, a major of them, significance of field practice, importance of human rights in their field, and finally, dearness of rapport building between social workers and clients in social welfare practice settings.

  • It is known that the ability and habit to "flow" could be one of the important indices to evaluate one's life. And the flow experience of university students who are in the important time transferring from the adolescence to the initial adult period will give an important effect firstly to study one's major and map out one's career path, finally to spread out the high quality life. This study investigated the university students who are in School of Mechatronic Engineering to experience the flow in the learning of PLC (Programmable Logic Controller) practice. For this, the flow condition was arranged. And in order to experience the flow in the learning of PLC, lecture plan was established, studying environment was changed and level of difficulty was controlled. Then the implications of the flow were explored by a 5-point Likert scale survey performed to 90 students.

  • This study identified the differences and relationships between clinical practice stress, sleep quality, and daytime sleep disorder before and after clinical practice of college nursing students. The subjects were 130 students in the third year of nursing science. The results showed that the average clinical stress of the study subjects was 3.15 out of 5 points. Out of the external factors for clinical practice stress, the score for the task was 3.64. There was a significant difference in gender (t=-3.88, p<).001), subjective health status (F=5.78, p=.004), residence (F=3.20, p=.026). Nursing students showed lower sleep quality (80.0% before practice, 70.0% after practice), and those with daytime sleepiness (26.9% before practice, 42.3% after practice) were more than those of general college students. There was a difference between sleep quality (χ2=4.06, p=.004) and daytime sleepiness (χ2=6.08, p=.009) before and after clinical practice. There was also a negative correlation between daytime sleepiness and sleep quality (r=-.259, p<0.01). Therefore, strategies to reduce clinical practice stress and improve the quality of sleep are needed for the physical and mental health of nursing college students. The quality of nursing can be improved in the future by helping nursing students adapt to the clinical practice of changing nursing education field.

  • The purpose of this paper was to suggest effective management of clothing department in vocational high schools. Bibliographic research on ten vocational high schools' clothing departments was done. Also a survey was done to figure out what students and teachers think of clothing department education. The results were as follows. There are ten clothing departments in vocational high schools countrywide. 1493 students are enrolled in the department and they are taught by 51 teachers. Each school has two to seven laboratories. Professional subject time assignment of clothing department varies from 82 to 112 hours. Students chose clothing department in order to enter the university and their satisfaction on the department was "fair." Students' satisfaction level of professional education courses was "fair" and they felt difficulties both in theory and practice. Students answered that Embroidery/Knitting courses should be closed and Fashion Coordination be opened. Students were "fairly" satisfied with facilities for practice and felt job training was necessary. Most of them wanted to enter university after high school graduation. Teachers answered professional education curriculum was "fair." They found it necessary to improve the textbooks and felt both theory and practice difficult. They wanted Embroidery/Knitting courses to be closed and Fashion CAD course to be installed. From the teachers' view, students' prospect was better to enter university than to get a job. Teachers suffered from too much teaching-unrelated workload and wanted the number of teachers to be increased. Considering the above results, vocational high schools should concentrate their efforts on making students continue to study by extending the way to enter the same department of university as department of vocational high schools. In addition, they should develop various practice programs through field practice and educational-industrial relationship to help students get jobs. Both teachers and students think that the clothing department curriculum is difficult now. Therefore, the level of the curriculum should be adjusted. Finally, it was necessary to increase the number of teachers and to carry out teachers' training to raise quality in education.

  • 컴퓨터 교육은 실습 위주로, 컴퓨터를 도구적으로 활용하는 소프트웨어 활용 수업이 대부분을 차지하고 있으며, 단순한 컴퓨터 활용의 실습 수업은 학습자로 하여금 흥미를 잃게 하고 문제해결력과 창의성 개발을 저하 시킨다는 문제점들이 제기되어 왔다. 이에 개정된 7차 교육과정은 이러한 소프트웨어 활용 위주 교육의 문제점을 인식하고 컴퓨터 과학, 원리 위주의 교육으로 변화 하였다. 본 연구는 개정된 제7차 교육 과정이 컴퓨터 과학 교육으로 변화됨에 따라 컴퓨터 과학의 내용을 보다 흥미롭고 쉽게 이해시키기 위하여 언플러그드 학습 시스템을 개발 하였다. 컴퓨터 과학의 추상적이고 개념적인 내용은 중등학교의 교육과정으로는 다소 쉽지 않은 내용이며, 이론 위주의 교육과정은 학생들에게 흥미 없는 교과로 비추어 질 수 있지만, 정보 교과를 위한 언플러그드 학습 시스템을 통해 흥미 있는 교과로 인식이 변화될 것으로 기대된다.

  • In this study, a related literature study was conducted to diagnose the status of overseas field practice and overseas employment programs, and a questionnaire was constructed and analyzed according to the CIPP model, and policy suggestions to promote effective overseas advancement programs in the future are presented. As a major result, it was investigated that in order to increase the satisfaction level of participants, it is necessary to have strong willingness to participate and to clearly set the goal of the overseas field practice and overseas employment program. In addition, it was analyzed that a system that can guarantee continuous support, such as local business trips and maintenance of relationships with companies, should be established even after successful overseas field practice and overseas employment. This study presents implications that may be helpful in establishing overseas field practice and overseas employment program policies of the national government, university, and local governments by confirming the positive effects and problems of current overseas field practice and overseas employment programs.

  • PBL is expected to be very useful in the engineering project course that leads students to active learning in problem solving process. But it is not actively utilized because of various problems. In this study, modified PBL lectures were laid out for a course that practice UX design process. Modified PBL lectures provide theoretical class and two PBL practices. The variant is that the problem design is made by the students themselves on a weekly basis, rather than by the instructor, and that the two PBL processes consist of one project. The results of this study are meaningful as a basic data in PBL-based engineering college project class. Additional discussion of how to evaluate grades needs to be specified.
