정주성,이강석 한국구조물진단유지관리공학회 2018 한국구조물진단유지관리공학회 논문집 Vol.22 No.1

On September 12, 2016, the Gyeongju District was strongly shaken with M=5.8, which was the largest one since measured by the actual seismometer in Korea, and some buildings were damaged. The field survey of reinforced concrete school buildings in the affected area was carried out, and their residual seismic capacities(R) were estimated based on the Japanese Standard for post-earthquake damage evaluation. In this study, the M school, which was greatly damaged by the 2016 Gyeongju Earthquake, was selected, and its damage level was evaluated on the basis of the Japanese Standard. The seismic capacity of the M school was also evaluated using the nonlinear dynamic analysis, and relationships between its damage level and seismic capacity was also conducted to investigate causes of earthquake damage. The damage level of M school was classified into light with R=88.2%. The result of the dynamic analysis agreed reasonably well with the damage of M school sustained by the 2016 Gyeongju earthquake. This will provide fundamental data for earthquake preparedness measures, such as the seismic rehabilitation of low-rise reinforced concrete buildings in Korea. 2016년 경주지진 이후로 국내에서도 본격적으로 건축물의 지진대책 강구가 시급한 시점에서 국내에 널리 보급되어 있는 R/C 건축물의 효율적인 내진성능 평가 및 내진보강을 포함한 내진대책을 위한 기초적인 자료를 얻고자, 2016년 경주지진에서 지진피해를 받은 R/C 저층 학교건축물(M학교)을 대상으로 지진피해도구분판정법을 이용하여 잔존내진성능과 지진피해정도를 평가함과 동시에, 부재수준의 비선형동적해석을 수행하여 지진피해정도와의 상관관계를 검토하였다. 지진피해도구분판정에 의한 손상도-I로 분류된 기둥은 2개, 손상도-Ⅱ가 1개, 손상도-III으로 분류된 기둥이 3개로 각각 평가되어, 최종적으로 평가한 내진성능잔존율(R)은 88.2%로 피해분류는 소규모 피해로 판정되었으며, 또한 비선형동적해석 결과 1층 X방향의 최대응답을 나타낸 기둥의 휨변위는 0.7 mm, 전단변위는 6 mm로 전단균열은 발생하였지만, 전단파괴는 발생하지 않았다. 경주지진에서 지진피해를 입은 M학교의 지진피해가 1층의 X방향에 집중되어 있다는 사실, 휨균열보다는 전단균열이 발생하였다는 사실을 고려한다면 본 연구에서 수행한 비선형동적해석 결과는 2016년 경주지진에서 지진피해를 받은 M학교의 지진피해상황을 잘 반영하고 있다고 사료되며, 국내 기존 저층 R/C 건축물의 효율적인 내진성능 평가 및 내진보강을 포함한 내진대책을 위한 기초적인 자료로서 활용가능하다고 사료된다.

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.

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.

所得再分配에 관한 硏究 : 公共勤勞福祉 增大方案을 중심으로 WITH EMPHASIS ON THE WELFARE POLICY FOR WORKING FAMILIES

정주성 단국대학교 대학원 1992 學術論叢 Vol.16 No.-

The purpose of this paper is to consider a properiety of the welfare policy for the working families as a positive redistribution policy in Korea. A redistribution function in capitalistic economy is the major part of government function because of the capitalistic economy has not an ability to correct the inequality automatically. Recently an income redistribution policy is emphasized by the working families in Korea. The reason is that the wages of the working families was raised in the last several years but they feel that they are low their real income and econnomic status rather than before on account of a speculation in real estate. So they demand intensively not only a raise in wages but an increase of welfare benefits for the real income rise. From this viewpoint, we can estimate that an expanison policy of working families welfare like 'the working families housing policy' is effective. Now an improvement of income distribution is not a bottleneck of growth but a precondition for growth in korea economy. It is important that we realize that the stabilization of prices and the eradication of speculation in real estate is the efficient redistribution policy.

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.

정주성,Jeong, Joo-Seong 한국교육시설학회 2018 敎育施設 Vol.25 No.6

To compare the physical quantity of students circulation along the moving path during recess of a variation type operation middle school, five points were actually observed. The flow coefficient for these points was calculated, and the change in flow coefficient was verified and tracked over time. During the operation of the classroom, the characteristics of crowdedness and congestion time depending on the physical conditions of the frequently moved paths were shown. Even in the same corridor, the difference between the flow coefficient and the congestion time of the corridor facing the open space and the blocked space was noticeably different. As a result, detailed factors such as free walking speed, the degree of freedom of passing and the possibility of collision were also identified. This means that detailed countermeasures for the student's path should be considered first when planning the moving space of a variation type school, and identifying the characteristics of these factors could be used as useful basic materials for developing various models of classroom space.

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.

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.
