This study is on the direction of betterment of density and suitability of residence in the highrise apartments. The conclusions are as follow ; 1) Depth per width in unit residence bring down about 1:1.5 in less than 25py., about 1:1.2 in less than 45py. And raise about 1:1 in more than 45py. 2) Building stories make high 12th to 15th Floor. 3) Pitch of building raise 1.0H to 1.25H. So that will be making more comfortable environment without bringing down density of houses in apartments.

In this paper, a simple recognition procedure of handprinted Korean characters is proposed. The procedure is based on the code table of 58 frequent character elements, and the code table was generated by the reduced classes of line segments i.e, "-", "1" and "0". With this procedure, 57.2 per cent of character elements are recognized by the numer of line segments and nodes and 85.7 per cent of remains are recognized by the line segmets which are conected to the maximum node. Four leften vowels are recognized by the existance of any line segment at the leftsied of the top-vertical line segment.

Low-viscosity composite resins may produce better sealed margins than stiffer compositions (KempScholte and Davidson, 1988; Crim, 1989). Flowable composites have been recommended for use in Class V cavities but it is also controversial because of its high rates of shrinkage. On the other hand, in the study comparing elastic moduli and leakage, the microfil had the least leakage (Rundle et al. 1997). Furthermore, in the 1996 survey of the Reality Editorial Team, microfills were the clear choice for abfraction lesions. The purpose of this study was to evaluate the microleakage of 6 composite resins (2 hybrids, 2 microfills, and 2 flowable composites) with and without load cycling. Notch-shaped Class V cavities were prepared on buccal surface of 180 extracted human upper premolars on cementum margin. The teeth were randomly divided into non-load cycling group (group 1) and load cycling group(group 2) of 90 teeth each. The experimental teeth of each group were randomly divided into 6 subgroups of 15 samples. All preparations were etched, and Single bond was applied. Preparations were restored with the following materials (n=15) : hybrid composite resin [Z250(3M Dental Products Inc. St.Paul, USA), Denfil(Vericom, Ahnyang, Korea)], microfil [Heliomolar RO(Vivadent, Schaan, Liechtenstein), Micronew(Bisco Inc. Schaumburg, IL, USA)], and flowable composite[AeliteFlo(Bisco Inc. Schaumburg, IL, USA), Revolution(Kerr Corp. Orange, CA, USA)]. Teeth of group 2 were subjected to occlusal load (100N for 50,000 cycles) using chewing simulator(MTS 858 Mini Bionix Ⅱ system, MTS Systems Corp., Minn, USA). All samples were coated with nail polish 1mm short of the restoration, placed in 2% methylene blue for 24 hours, and sectioned with a diamond wheel. Enamel and dentin/cementum margins were analyzed for microleakage on a sclale of 0 (no leakage) to 3 (3/3 of wall). Results were statistically analyzed by Kruskal-Wallis One way analysis, Mann-Whitney U-test, and Student-Newmann-Keuls method. (p=0.05) Results: 1. There was significantly less microleage in enamel margins than dentinal margins of all groups. (p<0.05) 2. There was no significant difference between six composite resin in enamel margin of group 1. 3. In dentin margin of group 1, flowable composite had more microleakage than others but not of significant differences. 4. There was no significant difference between six composite resin in enamel margin of group 2. 5. In dentin margin of group 2, the microleakage were R>A=H=M>D>Z. But there was no significant differences. 6. In enamel margins, load cycling did not affect the marginal microleakage in significant degree. 7. In dentin margins, load cycling did affect the marginal microleakage only in Revolution. (p<0.05)

본 연구의 목적은 선진적인 CSR의 모습을 보여주는 영국 CSR의 현황을 파악하고 한국에의 시사점을 제안하고자 하는데 있다. 연구방법은 문헌연구와 영국 현장을 방문하여 면접조사를 수행하였다. 연구결과, 영국 CSR은 세계적으로 선진적인 모델로 평가되고 있으며 특히 국가의 정책적인 지원과 노력이 활발히 진행되고 있다. 그 이유는 CSR을 세계화 시대에 국가 경쟁력을 높일 수 있는 전략적 국가 정책으로 보기 때문이다. 국가의 적극적인 CSR 정책, 시민사회의 전통적이고 네트워크된 CSR 활동, 선진적인 영국 기업들의 CSR 사례에서 영국 CSR의 동향을 파악할 수 있었다. 이런 결과를 토대로 한국 CSR에 주는 함의는 ‘인식의 확대와 공유’, ‘CSR의 국가 제도화’, ‘CSR 표준화 및 모델 개발 등의 과학화’, ‘국가, 기업, 시민사회와 비영리부문 각 영역에서의 실천화’, ‘CSR 네트워크 구성’ 등을 제안하였다. The purpose of this study is to examine the Status of Corporate Social Responsibility in the United Kingdom and Implications in Korea. Main findings are as follows. The case of United Kingdom is evaluated as the advanced model on CSR in the world. The model includes the support of social policy by state, the classical activities and wide network on CSR in NGO, the strategic CSR in company. Based on this results above, the author suggests the institutionalization, a scientific research and development, responsible practice and CSR network for the development of CSR in Korea.

본 연구는 미국의 거액전자자금이체에서의 지급지시의 효력을 검토하고 그 시사점을 제시한 것이다. 거액전자자금이체에서의 지급지시의 효력은 원지시인으로부터 구속력을 가진 지급지시의 발행, 수신은행의 지급지시에 따른 승낙, 그리고 수익자에 대한 체무이행으로 발생된다. 이와 같은 지급지시는 원지시인의 지급지시취소, 수신은행의 지급지시거절, 그리고 무권한적인 지급지시인 경우에 그 효력이 소멸된다. 즉, 원지시인으로서 입증된 전송자가 발행한 지급지시를 수신은행이 승낙하는 경우에만 지급지시가 정상적으로 이행되어 전자자금이체가 완료된다고 할 수 있다. 따라서 원지시인과 수신은행은 원지시인에 대한 입증과 지급지시의 진정성을 확보하여야 한다. 이러한 입증과 진정성 문제를 해결하기 위하여 관련 당사자들은 특히 보안절차의 확립에 관하여 약정하는 것이 중요하다.
