This study is carried out to understand spacial characteristics, actual condition and behavior of use about homebase managed in variation type. Observation about moving line of students and questionnaire were tried to satisfy this purpose. As a result, classroom used as variation type for long time stay and homebase outside the classroom for short time stay were paralled managed in most schools. Density of school furniture in homebase of observed schools was about 36-37%, occupying area of each student was about $0.3-0.6m^2$. It was relatively low with the results of 45-54% and $0.94-1.15m^2$ observed in Japan schools, respectively. By the analysis about behavior of use through cross section of observation, the difference of staying time and personnel exchange between the students was higher at the school having homebase composed with various corners more than the school used it only as a locker room.

정주성,Jeong, Joo-Seong 한국교육시설학회 2011 敎育施設 Vol.18 No.4

This study was carried out to obtain basic data for architectural plans about factors on the facilities relocation needed in management of variation type. For this, floor plans of thirteen middle schools located in Korea and Japan were compared. The results showed a successful conversion to block system according to each subject after remodeling in the schools of our country, however, a monotonous spacial composition excluded other spaces such as media space, teachers' station and preparation room was also shown. These mentioned spaces were important factors in the investigated schools of Japan. By the results of the spacial composition about each space required to the management of variation type, a space share of supplemental areas for learning activities and movement, had shown comparatively low share before remodeling, was improved to 6% and 11.6%, respectively. However, the spacial share of two areas were 16.8% and 12.9%, respectively, in the schools of Japan and it meant the distribution of area was more even than the cases of our country.

This study was carried out to observe movement behavior of students about a change of physical condition in moving space of variation type using simulation technique. The moving pattern of students was checked by SIMULEX program. The width of corridor was adjusted to 2.4m, 3.0m and 3.9m and a flow coefficient of simulation was estimated with the change of width. The wider the width of corridor was, the lower a flow coefficient was, and the difference was large when the width of corridor was narrow. It was also observed that the flow coefficient was relatively high in all types of corridor setup individual locker. Unit occupation area with the change of width was additionally measured, as shown in the results, the occupation density was low when the width of corridor was wide and a stationary time was short.

거주유형에 따른 흙주거 거주환경 선호 분석

정주성,김정규 대한건축학회 2007 대한건축학회논문집 Vol.23 No.1

The purpose of this study is to investigate residential characters and consciousness about housing environment concerned with earth housing, and to suggest basic data reflectible on the planning of earth housing. Residential characters and consciousness are investigated with one hundred fifty habitants and visitors in earth housing located in nationwide scale through interviews and questionnaire. The habitants totally show more affirmative responses about residential environment than the visitors, external image, functionality, amenity, usability, convenience, statical and dynamic ambiences are shown as important factors to residential consciousness of habitants and visitors. The difference is also shown in the viewpoint of residential environment about earth housing between visitors and habitants according to each characteristic. These results are considered to disprove earth housing do not properly reflect various demands of habitants. For this, actual data based on regional and sectional characteristics should be accumulated with consciousness that more systematic approach is needed in earth housing than until now.

This study was carried out to analyze moving awareness of students to physical conditions and attitudes on user's place to moving route. Moving awareness and route choice of students on variation type were grasped through questionnaire. As the results, the satisfaction degree, moving awareness and elapsed time for adaptation of students to physical facilities associated with moving class were antithetical to numbers of class and student. The more students, the more negative the moving itself. Especially, students showed a different tendency to route choice of high frequency moving and possession awareness of their belongings according to spatial nearness and composition of homebase. These basic data will be utilizable to suggest various model for composition and rearrangement of school space.

교과교실형 운영 중등학교 홈베이스 이용의식 분석

정주성,Jeong, Joo-Seong 한국교육시설학회 2013 敎育施設 Vol.20 No.3

This study was carried out to observe awareness of students using homebase on variation type, about a thousand students in four middle and high schools participated in questionnaire. By the analysis of questionnaire, degree of awareness regarded homebase as a base was relatively high in respondents of the schools having easy accessibility of the homebase, and thus, proportions of assigned space for homeroom, using frequency of homebase and time to stay were also high in the group showing high awareness about homebase. Especially, it is noticeable use of homebase was frequent in the schools having subdivided space in itself. This result suggested that the function of homebase as a base of the students can be very important factor to plan schools of variation type.

所得再分配에 關한 硏究 : 負의 所得稅를 中心으로 WITH EMPHASIS ON THE NEGATIVE INCOME TAX

鄭柱成 단국대학교 대학원 1989 學術論叢 Vol.13 No.-

The purpose of this paper is to consider a propriety of the negative income tax(NIT) as a positive redistribution policy in korea. NIT as a kind of welfare tax system that combines a social security with tax system is the plan that subsidizes a low income group below the tax exemption limit. And because that NIT can indude all the law income group below the exemption limit and secure a finance resources stably and raise the level of income guarantee and self-support by producing incentive of labor supply, we are able to say that NIT is superior to the existing transfer system. Also in considering that Korea economy have to improve a regressivity of tax burden and a distortion of income distribution, NIT is suitable as a positive redistribution policy. Therefore an introduction of NIT have to be considered positively as an income redistribution mechnism.

Calcium Sulfate와 생체활성유리 45S5 복합이식 및 Calcium Sulfate 차폐막의 골재생 효과

정주성,유선열 전남대학교 치의학연구소 2001 구강과학 Vol.13 No.4

The purpose of the present study was to investigate the effect of the composite grafts of calcium sulfate and bioactive glass 45S5 in combination with calcium sulfate barrier in the experimental bone defects. Twenty rabbits, weighing about 2.5kg, were used. Three artificial bone defects, 5×5×5㎣ in size, were made at the mandibular angle area. In the experimental group 1, the bone defect was filled with bioactive glass 45S5 and calcium sulfate; in the experimental group 2, the bone defect was filled with the composite graft of bioactive glass 45S5 and calcium sulfate and covered with calcium sulfate membrane barrier. In the control group, the bone defect was filled with blood and was spontaneously healed. The rabbits were sacrified at 1, 2, 4, 6 and 8 weeks after the operation. Microscopic examination was performed. The results obtained were as follows; In the experimental group 1, prominent new bone formation was observed in compared with the control group. In the experimental group 2, extensive osseous regeneration was demonstrated in compared with the experimental group 1. The bioactive glass 45S5 were minutely cracked at week 2, and connective tissues were migrated into inner portion of the glass particles through the crack at week 4. As a consequence, each glass particles may function as a nucleation-site for new bone formation. As the experimental time elapsed, the amount of new bone formation was increased in the two experimental groups in compared with the control group. These results suggest that the composite graft of bioactive glass 45S5 and calcium sulfate promote new bone formation, and the composite graft in combination with calcium sulfate barrier is considered as a potential method for osseous regeneration.
