This study examines the process to demolish official buildings of Joseon Dynasty in Suwon Hwaseong during Japanese colonial period. King Jeongjo built the new Suwon city and constructed the city fortress. Hwaseong Hawnggung and other official buildings were also built in Suwon Hwaseong. However Those buildings were demolished gradually and lost their identity during Japanese colonial period. The official buildings of Hwaseong Haenggung were classified into nine parts. 1) Central area of Hwaseong Haenggung 2)Nangnamheon(落南軒) 3)Uhwaguan(于華館) 4)Namgunyeong(南軍營) 5)Bukgunyeong(北軍營) 6)Gangmudang(講武堂) 7)Yiah(貳衙) 8)Jungyeong(中營) 9) Hoeryungjun(會寧殿). Bukgunyeong was the first demolished building in Suwon Hwaseong. Nangnamheon and Hwaryungjun were not destroyed during Japanese Colonial Period. from 1910s to 1930s most official buildings were demolished and new buildings were rebuilt.

BIM could be used for integrating project information through life cycle of building facilities. Also it could improve the accuracy and work efficiency through data interoperability with other disciplines. However, these benefits from adopting BIM could not be attained easily in real project cases. In order to make the most use of BIM and get the maximum benefits from it, the environments such as standards, guidelines and the related technologies are also could be supported. Therefore many countries are developing or already developed the technology roadmap for BIM. In this study, we tried to analyze the BIM technology status and develop the strategy for improve usability of BIM in Korea.

In many parts of the world, low cost housing used to be built and maintained by the governments, based on designs and detail specifications prepared by the public sector with construction carried out by contractors. Results vary due to differences in design standards, workmanship and property management, depending also on the neighbourhood's care of the estates and their pattern of usage. In the UK, where Private Finance Initiative (PFI) has been used for infrastructure projects, there have been successful cases of city estate being transformed by PFI. These PFI housing schemes involve new-build, refurbishment as well as facility management. Unlike traditional construction, which is based on prescriptive specifications, PFI housing is based on output specifications. A study has been undertaken to compare the two specification approaches as they are applied to housing estate. Results are enlightening and serve as good reference to cities such as Hong Kong SAR and Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.

The purpose of this study is to explore the factors that influence the purchase of AI speakers in China. We integrate the Unified Theory of Acceptance and Use of Technology (UTAUT) and Task-technology fit (TTF) model into one model and put forward assumptions. According to the characteristics of AI speakers, we selected 6 independent variables, such as Performance Expectation, Effort Expectation, Social Influence, Facilitating Conditions, Task and Technology-characteristics. The final impact on purchase behavior is evaluated through Task-technology fit and purchase intention. After counting 478 samples, through SPSS22.0 and AMOS analysis, hypotheses have been proved by strong experimental data, except facilitating conditions. These results also imply that improving the technical level of AI speakers and enhancing consumers' purchasing intention are the central line of marketing. Based on this, we put forward several suggestions to marketers, including strengthening the research and development of AI speaker technology, and building a circle of friends of AI speakers.

The Purpose of this study is analyzed that (l) How the public Libraries under the Japanese Rule since the end of the Yi-Dynasty were recepted and generated by the people and (2) How they were organiged and managed. (3) Also it examined that how they affected the development of the libraries of today. 1. The following are the analyzed results: Three types of the public Libraries under the Japanese Rule for a period of 36 years engaged busily in colonization were Private's Public Libraries, Local Self-Government's Libraries and the Central Governmental Libraries, and were in order established. 2. They were eatablished by individuals, Confucian School Foundation, Young Men's Clubs, School Associations, Korean brethren residing abroad, or The Press Centering around the Local Self-Governments and the Japanese Government-General. 3. In 1932 of the period of the Japanese Rule, the number of Libraies gained the summit and reached 80 Libraries. The Public Libraries including the Central Governmental Libraries remained in existence until the end of the War had been kept up the functions of the Libraries, but the Private Libraries operated by the Koreans were very small and poor. As a result, most of them were closed up and some Libraries transferred their controls to the public. Until the end of the war, only a little over 10 Private Libraries were Kept up. From the aspects of it's organization system, the most of their libraries replaced their chief librarians with non-professional county-headmen or Local supporters. From the aspect of collections, they wate mainly consists of Japanese books for the proper quidance of the public thought based on the ideology of Japanese Rule to Korea and on the industrial promotion rather than books about Koreanology or Western books. At that time, the Library users were with the jobless men and students as the central figures. And the next ranking by the social position of readers was children, farmers, merchants, industrialists, public servants, miscellaneous and educators. Their reading tendencies laid stress on linguistics and literature, physical sciences and medicine, While the reading trend of military sciences and medicine, while the reading trend of military sciences and engineering were very inactive. This was because the Japanese Government-General had not kept the military collections on file. Besides, they were reluctant to make Korean's learn the professional knowledge and so the main reference materials of technology not provited. Most of the Libraries put practiced in circulation services were very important circulation in withinder of the reading room rather than in outside of the Library building. On the other hand, their circulation services has above came with many limitations. As stated above, the public Libraries' managements and activitives under the period of Japanese Rule were the way and means to achive the colonial and imperialistic purpose of the Japanese Empire.

상업지역 내에 위치한 공원은 이용행태가 일반적인 근린공원과 다를 수 있으며, 인근 상업시설의 영향을 배제할 수 없다. 본 논문은 중심상업지역에 위치한 근린공원을 대상으로 주변 현황과 여건 변화에 의해 나타나는 공원 이용행태의 특성을 규명하여 추후 공원 조성이나 재정비 시 필요한 개선점 및 보완사항을 제시하고자 연구를 수행하였다. 그 결과, 국채보상운동기념공원과 2.28기념 중앙공원은 인근 지역의 지가가 높고 노후화된 건축물이 적은 반면, 경상감영공원 주변 지역은 지가의 하락과 함께 상업시설이 전반적으로 쇠퇴한 것으로 조사되었으며, 이용자의 연령대는 젊은 층보다 노년층이 많이 분포하는 것으로 나타났다. 공원의 이용목적에 있어 세 공원 모두 공원 내 시설을 직접 이용하기보다는 주변 상업시설 이용과 관련된 간접적인 형태가 많았으며, 공원이용자의 계층적 특성이 주변 상업시설 이용자와 유사한 특성을 갖는 것으로 확인되었다. 공원 이용만족도를 결정하는 요인은 각 공원의 특성 및 이용계층의 차이에 따라 다르게 나타났으며, 이에 공원 조성 및 정비에 있어 공원 외부 환경의 변화에 따른 이용계층의 영향을 필히 고려한 계획이 이루어져야 할 것으로 판단된다.

미륵사는 백제 무왕(재위 600~641)이 창건한 사찰로 이와 관련한 창건 기록이 "삼국유사(三國遺事)" 기이(紀異) 제이(第二) 무왕조(武王條)에 언급되어 있다. 서원의 미륵사지서탑은 해체 전 6층까지의 일부가 남아있었으며 미륵사지 내의 유일한 현존 건축물로서 최근 사리장엄 발견으로 639년이라는 건립연대가 밝혀졌다. 또한 백제 사찰의 발굴조사 자료가 축적되고 동아시아의 학술적 교류가 활발해지면서 미륵사지서탑의 조영을 당시 불탑 건축의 발전 과정과 연관시켜 해석할 수 있는 가능성이 한층 높아졌다. 따라서 본 연구에서는 미륵사지서탑의 축조에 적용된 구조원리와 1층 평면의 형성을 중심으로 6~7세기 불탑 건축의 발전과정에 있어서 대형의 불탑건축이 어떻게 이루어졌는지에 관한 기초적 연구를 시도하였다. 연구 결과는 다음과 같다. 첫째, 미륵사지서탑은 내부와 외부가 독립적인 개념으로 축조되었는데 이는 당시의 고층 불탑건축에서 나타나는 구조원리의 표현으로 보여진다. 영녕사 목탑지에서 확인된 탑실심체와 같이 내부의 구조체를 형성하는 개념과 유사하게 내부 적심을 형성하고 외부 부재를 부가하는 방식으로 축조된 것이라 판단된다. 둘째, 미륵사지서탑에서는 상부의 적심부와 동시에 심주석이 동시에 존재하는 혼합 구조를 표현하고 있는데 이는 중국의 영녕사 목탑과 같은 실심체의 구조보다 발전된 것으로 조팽성 불사의 심초석과 항토 실심체의 구조와 유사한 것으로 판단된다. 이러한 혼합 구조는 황룡사 목탑이나 일본의 목탑과 같이 내외진을 전부 목구조로 형성하고 심주가 독립적으로 지지되는 구조 방식보다 선행되는 것으로 볼 수 있다. 셋째, 미륵사지서탑의 경우 1층에 십자형의 공간이 형성된 것은 심주석에 위치한 사리 봉안에 의한 것일 가능성이 높다. 이는 심주석을 중심으로 하는 4방향의 구심적 공간이며 사리의 본질적 의미에 기인하여 백제 6~7세기의 횡혈식 석실분과 유사한 방식으로 축조되었다. 횡혈식 석실분의 축조기법은 사리가 봉안되어 있는 상징적 공간을 효과적으로 표현하기 위한 방법인 동시에 석재를 사용하여 축조된 서탑에 있어서 재료적 동일성으로 인하여 수용이 더욱 용이하였던 것으로 추정된다.

There have been increasing reports of mycobacterioses in man and animals caused by "atypical" or "opportunist" mycobacteria. At the presnt, "opportunist mycobacterioses" are not generally responsive to antituberculosis drugs, and therefore, create considerable problems with regard to chemotherapy and control measures. In recent years studies have been made to isolate opportunist mycobacteria from soil, house-dusts and tap-water. It seemed quite interesting to define the extent of circumstantial presence of "opportunist" mycobacteria and nocardia in the soils of school-ground of primary schools and middle-high schools. This communication is the results of pilot study to isolate and identify "opportunist" mycobacteria and nocardia from 504 soil specimens of 72 schools in Seoul City. 1. Of a total of 59 isolates from 504 soil specimens tested, 32 strains were identified as opportunist mycobacteria and 27 strains as nocardia. 2. Isolation rates of opportunist mycobacteria by the areas(of specimen collection) were as follows: 36.4% in the southern area of Han-River, 33.3% in the central area, 22.7% in the outskirt area and 16.6% in the intermediate area. There observed no apparent difference in the isolation rates both-between the areas and between primary schools and middle-high schools. However, a significant difference was noted in the isolation rates between the places of soil sampling in a given school(P<0.05), i.e., the highest was the soil of refuge heaps(15.2%), and tap-water pole area(11.1%), the school-lavatory entrance(9.7%), the school gate entrance(5.5%), and iron-bar play ground(2.7%). The soil specimens from the center of school ground and from school building entrance yielded none of mycobacterial isolates. 3. Isolation rates of nocardia by the areas were as follows: 33.3% in the central area, 31.8% in the outskirt area, 27.3% in the southern ares of Han-River and 11.1% in the intermediate area. As in the case of mycobacteral isolates, there observed no apparent differences in the isolation rates both between the areas and between primary schools and middle-high schools, but a significant difference was noted between the places of soil sampling(P<0.05), i.e., the highest was the soil of school building entrance(15.2%), and of school gate entrance(6.9%), refuge heaps(5.5,%), iron-bar play ground(4.1%), the school-lavatory entrance(2.7%) and tap-water pole area(2.7%), respectively. The soil specimens from the center of, school ground yielded none of nocardia isolates. 4. Of the 32 strains of isolated mycobacteria. 15 strains were slow-growing mycobacteria and the remaining 17 strains belonged to the rapid growers. Of the 15 slow-growers. 4 strains were M. scrofulaceum-szulgai complex, 3 M. gordonae, 4 M. terrae-triviale complex, 2 M. avium-intracellulare-xenopi complex, and 2 unclassified schotochromogens. Of the 17 strains of rapid growers, 12 were M. diernhoferi, 2 M. fortuitum-peregrinum complex, 2 M. vaccae and one M. flavescens. 5. Of the 27 strains of nocardia isolated, 11 strains were N. transvalensis, 5 N. convoluta, 5 N. erythropolis, one N. vaccinii, one N. polychromogens-paraffinae complex and 4 untypable strains of orange-pigmented nocardia spp.
