This study aims to investigate and analyze the overall recognition of the photovoltaic system for the application of BIPV(Building Integrated Photovoltaic) in Korea. For this purpose, a survey was carried on through questionnaires answered by 6 groups of experts such as construction engineers, registered architects, mechanical engineers, electrical engineers, university or college professors, and others who are ranked high in their companies or universities or colleges and who mostly seem to be eager to participate in the development of the PV system and to make a business of the system. The results of the survey are as follows: 1. About 95% of those experts who answered the questionnaire have known about renewable energy, and 93% of them are interested in solar energy as alternative energy 2. Host experts have a lot of information on the solar energy system, but have scanty information on the PV system. 3. The experts in the educational and research field have researched for the reasonable period of the participation in the development of the PV system and the period of making a business of the system. They judge that companies in the mechanical and electrical field will participate in the development of the PV system and will make a business of the system in 5 years. 4. The experts have thought that the PV system is designed not for economy but for the environment of the earth and that PV system technology in Korea is much lower than that in the advanced countries. 5. The experts hesitate to participate in the development of the PV system and to make a business of the system because they have little confidence in the economy of the PV system now and because they have thought that they will bear a great financial burden of construction cost 6. The experts judge that it is most desirable to apply the PV system to the rooftops of buildings. And they are greatly interested in the BIPV.

Purpose: Laws and regulations of land use are enormous, and the appliance of regulations is overlapped redundantly. Therefore, there are many problems such as time consuming in the process, limiting individual property rights, and interrupting enterprises' economic activities. This study will discuss problems of redundant regulations of land use and its improvement by figuring out current regulations of land use in Gyeonggi-do, one of provinces which applies the most various regulations of land use. Method: This study reviews laws on national land-use planning system and characteristics of land-use regulation in Korea. The extent of the review is limited to "framework act on the regulation of land use" with categories of national land, urban planing, architecture, etc. Through case studies in Gyeonggi-do, the status and problems of redundant regulations of land use are defined. For example, it is overlapped in "Seoul Metropolitan Area Readjustment Planning Act", Development Restriction Zone, Paldang Special District, and so on. It is mainly referred to 2015 Gyeonggi-do land-use restriction map. Result: First, Gyeonggi-do confronts many problems related to the development restrictions and the financial increasement for environmental management by redundant regulations. The development restrictions include supplying additional land for industrial use, relocating colleges, and height limitation relating to military facilities. Second, in order to organize redundant regulations, it is required to combine similar regulations and adjust through communication system among other departments. Third, regulations should consider unique local condition of each district. Lastly, efficient application of regulations is necessary so as to maximize the function of land, protect individual property rights, and stimulate local development.

As the institute of education teaching radiologic technology in Korea, different from others, junior college is the only institute which has been managed for it as a two-year educational course for 27 years since 1963 when it was established for the first time in our country irrespective of the needs of the times. But according to the development of medical equipment, variety of medical skill, increase of medical demands now a days, the supply of radiologic technology in modern medicine not only makes it advance as an inevitable factor but also broadens the area of its business systematically. Therefore, we got the following results after we had considered the necessity to lengthen the term of education and searched for the most reasonable way. 1. The term of study of the radiologic technologists in junior college must be lengthened to 3 years from 2 or 3 years regulated in the law of education. 2. In three-year curriculum, the subjects like basic medical science, science and engineering and ultramodern science, etc., which are lated to the new radiologic science must be taught in the junior colleges, and hospital practice also must be a compulsory subject in curriculum. 3. As the school years becomes longer, a lot of programs to make the study effective must be searched, researched and propelled forward.

Recently, as the education population of Korea has been rapidly declining, many changes have been taking place in the university environment. Especially, community colleges linked to local communities have responded to these crises through various educational changes, such as three-year study transfers, work-parallelism, and employee commissioned education. However, such changes in the contents of education are causing a new type of classroom allocation problem, in which it is difficult to assign the limited number of classrooms to the major courses. In this paper, we classified the constraints involved in assigning classrooms into absolute constraints and relative constraints, mathematically modeled them, and allocated the classrooms optimally through optimization software. The results were satisfactory and enabled us to obtain superior results in terms of the various performance indices (classroom utilization rate, teacher satisfaction, etc.) than when assigning classrooms in the normal way.

This paper proposes a variable passive harmonic filter for reduction and improvement of harmonics and power factor of single-phase uninterruptible power supply(UPS) with full bridge rectifier. Recently, UPSs have excellent harmonic and power factor operation characteristics by applying 2-level or more levels of power conversion methods. On the other hand, the single-phase UPS of the full bridge rectifier seriously causes the third, fifth, and seventh harmonics, and the power factor reduction on the grid side. Therefore, we present a variable passive harmonic filter for eliminating (2n+1) order harmonics and improving the power factor generated by the full bridge rectifier operation. In order to evaluate the performance of the proposed variable harmonic filter, the its validity is verified by various simulations and experiments.

Convergence education, which is operated by many engineering colleges, is mainly led by government-led projects. Convergence majors are established in consideration of the research field of the university professors rather than systematically analyzing the needs of the industry. The purpose of this study is to present the directions of convergence technology education related to new industry fields by analyzing industry needs. Participants were 299 industrial workers in various fields. Instrument consisted of three parts: necessity for convergence education, demand for convergence new technology education from industry perspective, and opinions about undergraduate convergence education. As a result, it was found that the level of awareness of industry needs for fusion technology education was high, and it was confirmed that there is a high demand for IoT convergence, bio-health, advanced new material, and renewable energy fields among convergence technology fields. In addition, the results of the industry demand for convergence new technology education were presented. The suggestions for expectations, problems, and improvements in undergraduate education were presented and implications for convergence technology education were discussed based on the results of the study.

In line with the recent job insecurity, the preference for teaching jobs has been increasing for private and educational colleges. However, the T.O., announced by the Ministry of Education in tandem with the decreasing number of people, is decreasing every year, while the competition rate is rising steeply due to the increase in the number of students. As a result, the university is becoming a huge hagwon for teacher-nominee competitive tests as it tries to concentrate on the recruitment exam at the same time as entering the university. In this study, we will present a blueprint for school life to students enrolled in private universities by identifying the connection between the overall use of school life and study groups by students using deep learning.

Urban campus, one of the main urban facilities, is the representative place that is struggling with 'gridlock'. Due to privatization of space among different departments and space shortages, gridlock has been occurring as a result. The urban campus trying to solve this problem by changing the quality of space, especially the structure of the shared space, which is expected to be the solution to the grid lock problem. The main purpose of this study is to investigate the structural change in the university's shared space based on paradigm transition. The theoretical consideration is to analyze the spatial characteristics of university shared space that appear at different stages through a new perspective that compares the gridlock phenomenon and the shared paradigm. The framework of the analysis of the shared space, which has recently been restructured, is classified into the spatial characteristics of collaborative space, the creative space, and the common/complex space. In addition, these spatial characteristics are again analyzed through the division of legislative facility classification, management governance subject, area, building location and layout, exposure to the outside as well as the analysis of student and staff entry and exit, sharing structure of site and space, and the classification of program characteristics. The results are as follows: The restructured space is systemized so that the management governance of each space would be connected to each other to share information and space. Furthermore, the spatial boundary between colleges or between campus spaces are not only physically, but categorically clear. The restructured space has semi (or in-between)-spatial characteristics such as the intersection in inside and outside of the pedestrian's circulation and the mixture of programs. This study could serve as principal references in presenting the systematic analysis of directions of the shared spatial structure for the urban campus where new educational space is required due to the changes in the university system.

Recently, as interest in appearance has increased, various studies on treatment method for short stature are being conducted. In this study, the effect of growth plate stimulation on the height growth of children and adolescents was studied. As a result of pre- and post-analysis of the experimental group, it was confirmed that the difference in average height according to growth plate stimulation was relatively large. In addition, in the results of analyzing the effects of demographic factors on the height growth of the experimental group and the control group, weight showed the greatest influence on height growth among the demographic factors affecting the height growth of the experimental group. The effect on the height growth of the control group was found to have an effect in the order of age, weight, and father's height. The difference in height changed post-mortem between the experimental group and the control group was 1.10 cm for 3 months, and the difference was the result of growth plate stimulation. It was confirmed that growth plate stimulation had a significant effect on the height change of children and adolescents, except for weight, which is a common factor of height change in the experimental and control groups. Therefore, it is expected that it can be used as a treatment method for short stature.
