캐이블 구조물의 형태에 따른 비선형 해석

박강근,김한철,최영화 대구대학교 2006 대구대학교 학술논문집 Vol.1 No.2

캐이블 구조물은 여러 가지 형태를 가진 대공간 구조계에 적용되고 재료에 대해서도 효과적으로 적용된다. 캐이블 구조의 재료적인 특성은 축방향 강성이 크고 휨강성은 적다. 또한 케이블 구조는 초기에는 불안정 구조물이다. 이러한 유연 구조물은 기하학적으로 비선형을 고려하여야 하고 초기에 불안정 구조물이고 대변위 현상이 발생되기 때문에 구조해석을 수행하기 전의 평행된 형태를 연구하여야 한다. 비선형 정적해석은 Total Lagrangian 식과 수정된 Newton Raphson 법을 이용하였다. 본 연구에서는 케이블 돔의 변형형태를 해석하고 비선형 유한요소법으로 케이블 부재의 기하하적 비선형 해석을 하였다.

서울시 인구의 공간변화 경향에 관한 연구

金根永,강희진 강남대학교 산학기술연구소 2001 산학기술연구소논문집 Vol.- No.11

Population is an important socio-economic index that explains levels of urban development, current conditions of residential environments, locations of public and private facilities, and socio-economic activities of residents in a city or region. The Seoul city region with over ten million residential population(over 20% share of national population) within an area of 605.5km2(only 0.6% share of national area) has recently experienced the dynamic migration of city residents from central districts to suburb areas at the peak of 10.97 million population in the year of 1992. The objectives of this research are: (1) to investigate the dynamic patterns of Seoul residential population that is already declining with respect to five regional groups of central, northwest, northeast, southeast, and southwest regions provided by 『2011 Seoul City Regional Plan』, (2) to evaluate annual population changes of Seoul jurisdictional Dongs using statistical analyses, and (3) the spatial distributions of Seoul population using a geographic information system. To do this, this research collects annual, Dong-based population data from Seoul statistical yearbooks from the year of 1979 to 1999. This research also applied correlation analysis, hypothesis testing of two non-independent paired data, and spatial analysis using SAS v. 6.12 and Mapinfo v. 4.1. Results from general pattern investigation show that the population of Seoul region is declining since the year of 1992, though the population of the Seoul metropolitan region still increases. This declining population is not the spatial case in one area, but the widely observed, fundamental trend. Results from statistical analyses present that all of correlation analyses and most of hypothesis testing provided significant test outcomes within the 99% significance level. This means that the population number of Seoul city is dramatically changing during most of the study period. The spatial analyses using Mapinfo software clearly show the suburbanization pattern of Seoul population.

This study started with the measured experiment of climatic characteristic at the coastal reclamation area formed by the reclamation and development which is inevitable selection presently. As a result of the examination, the climate variation is predicted to be large in summer and the salt concentration is shown in the order of top layer, bottom layer and intermediate layer. Therefore, the greens space and wind path are occupied at the coastal reclamation.

This thesis is the study on the magnetic properties of strontium (Sr) ferrite. Specimens of SrO·nFe₂O₃,basic composition, with n=5.9 which is nonstoichiomatric composition region were prepared by sintering at 1275°C for 1hr, whthin air surroundings. In order to increase coercivity, additives of 0.4wt%SiO₂ and 0.7wt%CaCO₃ were added into basic composition, and 0.5wt%∼2.0wt%Cr₂O₃ was added as second additives. In case of second additives 1.5wt%Cr₂O₃, it was obtained uniformed grain size and magnetic properties was increased. The sintering temperature was 1150°C, 1180°C, 1210°C, 1240°C and 1270°C respectivily and cooling was performed in furnance. From the research and experiments on the magnetic properties of strontium (Sr) ferrite based on the complex additive technique, it was obtained good magnetic properties of (BH)mas=0.72MGOe, at the sintering temperature of 1210°C, in the case of (basic composition)+(basic additive)+(1.5wt%Cr₂O₃)

정신분열병의 유병기간과 인지적 결함간의 관계

이근창,이종학,강병조 대한생물치료정신의학회 1996 생물치료정신의학 Vol.2 No.1

정신분열병에 대한 현행의 개념이 손상된 인지기능이 이 질환의 정신병리중의 하나라고 받아들여지고 있다. 그러나 정신분열병의 경과가 점진적이고 지속적인 손상을 유발하는 진행적인 치매적 장애인지 급성 또는 아급성과정에서 인지기능의 감소가 오고 결국은 비교적 안정된 결함 상태가 되는 정적뇌병증인지에 대한 논란은 아직도 계속되고 있다. 본 연구에서는 58명의 정신분열병환자들을 유병기간에 따라 5년이하(Group 1), 5년초과에서 10년이하(Group 2), 10년초과에서 15년이하(Group 3), 15년초과에서 20년이하(Group 41)의 4군으로 분류하여 정신분열병환자들에서 유병기간이 증가함에 따른 인지기능의 차이가 나타나는 지에 대해서 WCST, VCPT, 재인기억검사, 공간기억검사, 수지럭검사, KWIS 어휘문제 및 BPRS를 시행하여 다음과 같은 결과를 얻었다. 1) 각 군간에서의 간이정신평가척도(F=0.22, d.f.=3,54, P=0.88)는 유의한 차이가 없었다. 2) Wisconsin카드분류검사(F=0.23, d.f.=3,54, p=0.87), 시각지속수행검사(F=0.27, d.f.=3,54, P=0.84), 공간기억검사(F=0.10, d.f.=3,54, P=0.96), 재인기억검사(F=0.15, d.f.=3,54, p=0.93) 수지력검사(F=1.20, d.f.=3,54, p=0.32), 어휘문제(F=0.67. d.f.=3,54, P=0.98) 등 실시한 모든 신경심리검사에서 4군간에 유의한 차이가 없었다. 이러한 결과로 볼 때 정신분열병은 유병기간과는 무관한 정적뇌병증일 것이라는 것을 시사한다. Most current thinking about schizophrenia acknowledges that impaired cognitive performance is one of the manifestations of the neuropathology of the illness. But, controversy surrounds the issue of whether a dementing disorder which produces a gradual and progressive loss of cognitive function or a static encephalopathy which is a relatively stable deficit state followed after cognitive function diminishing during an acute or subacute process. In this study, 58 schizophrenic patients were assigned to four duration of illness-derived groups: duration of illness≤5years(group 1), 5<duration of illness≤10years(group 2), 10<duration of illness≤15years(group 3), 15<duration of illness≤20years(group 4). To ascertain the significant differences of the cognitive function between 4 duration of illness-derived groups, WCST, VCPT, recognition test, spatial memory, finger tapping test, KWIS-vocabulary test, and BPRS were performed. The results are as follows ; 1) There was no significant differences between 4 groups on BPRS(F=0.22, d.f.=3,54, P=0.88). 2) There were no significant differences between 4 groups on WCST(F=0.23, d.f.=3,54, P=0.87), VCPT(F=0.27, d.f.=3,54, P=0.84), spatial memory(F=0.10, d.f.=3,54, P=0.96), recognition test(F=0.15, d.f.=3,54, P=0.93), finger tapping test(F=1.20, d.f.=3,54, P=0.32), KWIS-vocabulary test(F=0.67, d.f.=3,54, P=0.98). These results suggest that the course of schizophrenia is more consistent with a static encephalopathy than a dementing disorder, irrespective of duration of illness.

崇禮門 연구(1) : 修理史와 復元의 意義 About Restoration. and the History of Maintenance

李康根 한국불교미술사학회 ( 구 한국미술사연구소 ) 2002 강좌미술사 Vol.19 No.-

This study attempts to rewrite the maintenance history of Sungnye-moon(崇禮門) and re-illuminate the restoration in 1960's. Sungnye-moon was Great South Gate(南大門) of Seoul Walled Fortress(漢城) in Joseon Fortress Architecture. The wooden superstructure is a two storied pavilion, five kan (間) wide in the front and two kan on the sides, with a hipped roof. The base structure is made of granite blocks pierced by a single arch for the gateway. There were many functions in this gate as follows; the gateway to Joseon, the entrance and exit of Seoul City Wall, the symbolic direction of fire, a bell pavilion, the place for a farewell party, the place which King examine a rebel etc. But nowadays this gate turned into the monument of modern Seoul Metropolitan City. This gate was first constructed in 1398(the 7th of King Taejo) and reconstructed in 1448(the 30th year of King Sejong) and in 1479(the 10th year of King Seongjong) and has been repaired many times in Joseon Dynasty. In 1960's the wooden structure(門樓) and stone structure(陸築) was entirely pulled down and re-assembled, that is, restored. Under restoration, firstly the responsible person in charge of affair realized that this gate originally had a hip-and-gable roof but it was reworked into a hipped roof. Secondly the decorative members, such as a structurally useless bracket on the upper part of column, and the wall between bracket sets were regarded as newly added parts and therefore removed. But Nobody knows when the removed parts are added? So there are a lot of problems about restoration in 1960's Indeed what is the original form and style? Now we understand this gate is a rebuilt building in the reign of King Sejong. and so a representative of Early Jeseon Architecture. So about architecture in Early Joseon Period, there needs advanced studies. In next study, I will try comparative analysis between Sungnye-moon and other buildings in Early Joseon Period from the viewpoint of stylistic change.
