The purpose of this study is to suggest an improvement plan for the National Technical Qualification Practical Evaluation focusing on National Competency Standards. First, in order to strengthen practical techniques such as field abilities and expertise, practical evaluation methods were applied to the National Competency Standards, referring to a learning module focused on field performance. Second, an expert advisory committee in the field of organic agriculture was utilized to compare, analyze, and match the competency unit and competency unit elements of the National Competency Standards with the national technical qualification examination standards in field of organic agriculture. In addition, in order to identify work in progress in the industrial field, share professional practice skills, and analyze facilities and equipment, we visited an organic agriculture industry site. Through this, a practical evaluation exam was developed. Subsequently, in order to confirm the adequacy of the developed exam, the pilot test assessment was conducted for those majoring in organic agriculture. Finally, as a feasibility study, a survey was conducted. Based on the results, greater technical job competency in the field of organic agriculture will contribute to strengthening knowledge in this field by suggesting an improvement plan for the national technical qualifications practical evaluation method in the field of organic agriculture.

This paper describes the PI controller design based on a practical transfer function model for centrifugal water chillers. The rotational speed of a compressor and the opening angle of an electronic expansion valve were simultaneously regulated as manipulated variables to maintain temperature reference and to ensure high efficiency of the chiller. The COP according to the change in each variable was investigated by performing some static experiments, and it was reflected in the PI controller design to accomplish the high efficiency control. Especially, the practical transfer function model of the chiller was built based on the dynamic experimental data considering the strong inherent non-linearity and complexity of the chiller system. The validity of the designed PI controller was proven by some experimental results using the test facility and the results were also compared to the conventional evaporating pressure control results.

According to "The regulations regarding the residential construction standards", residents' common spaces are restricted by the standards on building facilities. In a typical apartment complex, residents' communal facilities are represented by a children's playground, a elderly social station, and a management office. However, these residents' communal facilities do not reflect residents' composition characteristics. Multidisciplinary research and experimentation to enable the community of housing complex are being actively conducted. In these situation, we observed institutional improvement about installing standard of community space, and analysed the tendency. The purpose of this study is to propose practical institutions to review the institutional improvement. We conducted a case study where was renovated the community space according to the new standard. As a results, the installing standard of the community space has changed in the direction to increase the autonomy of resident. These results raise the practical performance of the community space, and it has the effect of increasing the satisfaction of the residential environment. The results of this study suggest an alternative to the institutional aspects and planning aspects for community activation in housing complex.

The purposes of this study are 1) to identify the position and the problems of Home Economics in Elementary School, and 2) to propose orientation for the future curriculum revision. Elementary Home Economics, historically, has been partially practiced as a part of Practical Arts Education. As a results, the nature of Home Economics Education has been distorted and lacked the disciplinary consistency with Middle School Home Economics Education： the curriculum of Home Economics Education ignored the importance of the understanding family life as well as underscored the technical skills. The identified status and problems has on implication for the subject’s further development. The propositions for Elementary Home Economics Education which has the original intention, are as follows：(1) the curriculum of Practical Arts Education must be built on theorectical base and criteria. (2) the name of subject, Practical Arts Education, must be changed to [Technology$.$Home Economics]. (3) the contents of the subject must be practical which to promote motivations and interest of students.

Purpose: The current education curriculum centering on the national examination can not train the human resources needed for the clinic. Therefore, we would like to develop a curriculum for practical education and cultivate talented people capable of working in clinical practice at the same time. Methods: This study investigates the importance and utilization of the subjects by using qualitative and quantitative mixed research methods through interviews with FGI and structured questionnaires for grades 2,3,4. Results: In order to carry out the related work, all the subjects need more practical training, and the curriculum that can learn the latest prostheses such as CAD / CAM, implant, 3D printer, Conclusion: In order to carry out the related tasks immediately after graduation, practical education through improvement of curriculum is needed.

In the study, for the practical approaches of job shop scheduling, we propose the new dispatching rules of job shop scheduling in order to complement the practical applications in the existing researches. The assumed situation for the practical approaches considers the following; relaxation of assumption for capacity constraint by machine flexibility, the addition of the common use of jig and fixture, unbalanced machine workloads and duedate tightness, and produces fast rescheduling that reflects unexpected situations. The performance of the new dispatching rules is compared and analyzed with the existing methods through the computer experiments in the assumed conditions. The results can be useful to improving a field application of the job shop scheduling.

Nursing majors are a combination of theoretical and practical education, and since the advisor cannot participate in all practices in clinical practice, the efficiency and effectiveness of practical education are limited in judging the results according to students' reactions. Therefore, the purpose of this study was to analyze the domestic literature on the efficiency of clinical practice of nursing college students.The analysis target was selected through PRISMA flow, and the results were derived through categorization and questioning based on content analysis. Looking at the results, research related to the adaptation of trainees was mainstream, and specifically, research related to the characteristics, conflicts, clinical practice environment, and interpersonal anguish of trainees was conducted. In addition, it was confirmed that active and systematic intervention of practical guidance professors was required, such as possible safety accidents, emotional labor problems, and dilemmas during the practice period. Through this study, it is suggested that a systematic framework for nursing and clinical practice should be prepared.

This paper presents a possible methodology to develop a facility layout using practical constraints. Those factors considered in the system are not only used for the evaluation of layout but also for the search to solution on the design process. Necessarily, this method develops practically feasible solutions with less iterations since the infeasible alternative layouts are rejected by the practical constraints before evolutions. The suggested method is implemented in FORTRAN for experimental purposes and the results are discussed in detail.
