The purpose of this paper is to evaluate facade design factors of old dwellings using a Fuzzy Analytical Hierarchy Process (AHP) based on a pairwise comparison analysis using "Façade Design Factors" as evaluation criteria. Traditional old dwellings were presented and evaluated. A Fuzzy AHP based model was used for pairwise comparison of traditional old dwellings, whereby seven criteria and nine alternatives were described through a questionnaire and constructional data. The Fuzzy AHP was used to determine the impact of the facade design factors, because "Traditional" old dwellings are identified by the combination of their facade design factors. Furthermore, the fuzzy AHP is used to verify the feasibility and efficiency of this approach as well as for extent analysis to comprehend the priority of the traditional old dwellings using a sensibility measuring scale.

The purpose of this study was to delve into all sorts of literature concerned in a bid to suggest how the Public Law Enforcement and private Security sector could join forces in preventing crimes and guaranteeing the safety of people. Quite naturally, crime has increased greatly to become one of the major social problems. Crime has been conventionally recognized as 'something' to be prevented and controlled by public law enforcement. However, the rate of crime increase has been so rapid that public law enforcement alone could not effectively control the everincreasing and diversified crimes in our society. To serve as a qualified partner for the police, private security industry should strive to secure excellent manpower and provide education for workers to improve their qualifications. Specifically, they should put sustained efforts into diversifying the types of security business and creating a new market to extend their scope of business and become more competitive. Intensified collaboration between the Public Law Enforcement and private Security security sector is expected to create new synergy in addressing people's needs for safety and enhancing their quality of life.

How will South Korea design well-organized, open, and integrated counterterrorism system? Does this system work well in the emergent situation? These are very significant issues. It is likely that this system would give the solution. A legal basis needs to be established to have a well-organized, open, and integrated counterterrorism system. The core part of a well-organized, open, and integrated counterterrorism system is to minimize and eliminate damage caused by terror through preventiveness, preparation, action, and restoration. For having this system, they need to be divided into two section: an open one and an integration one. In this study, there will be a discussion on a new and appropriate counterterrorism system fit in South Korea a subordinate system: legal, organized, civil aspects need to be provided on the basis of an well-organized, open, and integrated counterterrorism system and an analysis on the current system of the States, England and the following implications.

사회생활을 하는 사람이라면 하루에 꼭 한번 정도는 하는 일이 있다. 출퇴근, 회의, 그리고 자판기 이용이 그것이다. 이른아침 출근을 위해 지하철 무인 패스 판매기를 이용하고 출근해서는 나른한 오후시간을 깨우기위해 으례 커피자판기를 이용하기 일수이고 여가시간을 이용해서는 친구들과 가벼운 스티커 사진촬영을 하는 등 우리의 자판기 이용 문화는 이미 현대인 너무나도 보편화되고 친숙해져버린 생활의 한 단면이 되어버렸다. 그렇다면 자판기는 언제쯤 인간의 일상사 속에 등장하기 시작했을까? 놀랍게도 자판기의 기원은 기원전 215년으로 거슬러 올라간다. 당시 이집트 사원에서 `성수(聖水)`를 판매하기 위해 만들어졌던 동전식 조작장치가 최초의 자판기라는게 정설로 받아들여온 사실로서 동전을 넣으면 투입된 동전이 받치고 있던 접시가 기울어져 그 기울기가 원래대로 돌아올 때까지 출구로 물이 나오는 원리를 이용한 것이다. 누가 만든것인지는 명확히 밝혀지지 않았으나 확실한 것은 자판기의 역사가 이미 기원전으로 거슬러 올라가고 인간생활에 뿌리내린 역사가 깊다는 것이다. 아무튼 이렇게 자판기가 나타난 이래로 17세기에 키산드리아 과학자 헤론이 쓴 책이 발견되기 이전까지 자판기는 잊혀진 발명품이었다. 그러나 그 책의 발견과 함께 사람들은 옛문헌 속의 발명품의 실용성에 관심을 기울이기 시작했고 차츰 영국의 선술집과 여관 담배 자판기가 등장하기 시작했으며 자판기는 식민지까지 보급될 정도로 선풍적인 인기를 끌었다. 19세기에 들어서는 담배 이외의 물건을 판매할 수 있는 자판기에 관심을 두기 시작했고, 자유주의 사상이 풍미하던 시절, 영국에서 나타난 금서(禁書)자판기에서부터 상업문화가 발달한 미국의 껌볼 자판기에 이르기까지 자판기는 점차로 그 영역을 넓혀갔고 또한 발전해 왔던 것이다. 그러나 자동판매기의 이러한 급속한 발전과 소비영역에서 역량의 강화는 비단 단순한 소비패턴의 변화에서 기인하는 것이라고는 보기 어렵다. 이는 노동집약적 산업구조에서 기술집약적 산업사회로의 전환에 따른 대량생산, 대량소비, 소비패턴 변화 등의 마케팅 환경의 변화에 따라 새로운 유통구조의 출현이 요망되었기 때문이었다. 따라서 슈퍼마켓, 쇼핑센터 등의 새로운 유통구조의 출현 외에도 인건비의 상승, 장소의 제한 및 구입의 편리성 등에 따라 무인 자동판매기의 등장은 필연적이었다고 볼수 있다. 이후 자판기의 판매상품의 범위는 더욱 넓어졌고 컵라면, 인형, 마음에 드는 음악만을 골라담는 CD,휴지,구두광택기,사진스티커,콘돔,장난감,담배,여행용품,스낵,아이스크림 등등 소액권과 손가락만 있으면 살 수 있는 물건의 가짓수는 헤아리기 어려울 정도가 되었으며, 그만큼 유통혁신의 기구로서 산업에 미치는 영향 역시 증대되고 있으며, 이러한 경향은 21세기 정보화,첨단화 경향에 발맞추어 더욱 진보된 형태로 발전해오고 있다.

Heat shock proteins serve as chaperone by preventing the aggregation of denatured proteins and promote survival of pathogens in harsh environments. In bacteria, ethanol shock induced the major chaperone GroEL and DnaK, but in Streptococcus pneumoniae, it induced neither GroEL nor DnaK but alcohol dehydrogenase (ADH). In this study, ADH gene encoding a 104-kDa (p104) protein was identified and characterized. The deduced amino acid sequence of pneumococcal ADH shows homology with other members of the ADH family, and particularly with Entamoeba histolytica ADH2 and E. coli ADH. S. pneumoniae adh is composed of 883 amino acids and its estimated isoelectric point is 6.09. Although ADH is conserved between S. pneumoniae and E. coli, immunoblot analysis employing antisera raised against pneumococcus ADH demonstrated no cross-reactivity with ADH analog in Eschericha coli, Staphylococcus aureus and human HeLa cells. Also secretion of ADH was demonstrated by subcellular fractionation and immunoblot analysis of proteins. These results suggest that S. pneumoniae ADH could be a highly feasible candidate for both diagnostic marker and vaccine.

Molecular analyses of natural microbial communities are often dependent upon the obtainments of pure nucleic acids. The four methods (elution after agarose gel electrophoresis, G-75 microspin columns, hydroxyapatite mi-crospin columns, and polyvinylpolypyrrolidone (PVPP) microspin columns) were compared for the removal of PCR-inhibitory humic substances from the crude DNA extracts of marine sediment samples. The PVPP microspin columns have shown superior removal of humic substances from the crude DNA extract of marine sediment samples, with yield of $4.8{\mu}g/g$ (dry weight of sediment). The purified DNA by this rapid method was pure enough to amplify 1.5 kb fragment corresponding almost full length of 16S rRNA genes.

The Genetic Algorithm is one of the population surface modelling tool in the field of urban and environmental research based on the gridded population data. Taking the East-Hwasung area as the case, this study first builds a gridded population data based on the GIS databases as well as municipal population survey data. The study then constructs the attribute values of the explanatory variables by way of GIS tools. The regression model constructed with the same variables is also run as a comparative purpose at the same time. It is shown that the GenAlg output predicted as much consistent and meaningful coefficient estimates for the explanatory variables as the regression model, indicating that it is a very useful interdisciplinary research tool to find optimal solutions in urban problems.

For the implementation of large scale GRID systems, the performance scalability in resource scheduling is clearly to be addressed. In this research, we analyzed existing scheduling frameworks from the viewpoint of the performance and propose a novel resource scheduling framework called resource parameter based scheduling. Proposed scheduling framework consists of three components. The first is the resource parameter graph that expresses resource information via inter-resource relation and the composition base on the hierarchical structure. The second component is the resource parameter tree to be used for the implementation of the memory-based index of resource information. The third component is the resource information repository which mostly consists of static data to be used for the general resource information services. This paper presents the details of the framework.

We prepared the cylindrical $\gamma-alumina$ pellets of 5 mm in diameter and 10 mm in average length using amorphous alumina and pore generating agent. The pellets were immersed in an aqueous solution of the mixture of $Fe(NO_{3})_{3}{\cdot}9H_{2}O$ and $CH_{3}COOH$. They were then hydrothermally treated at $200^{\circ}C$ for 3 h in autoclave, dried and calcined. For the application as an environmental catalyst, we investigated the decomposition characteristics of aniline and the initiation characteristics of $OH^{\cdot}$ conversion action in $O_{3}$ environment with or without the $Fe_{2}O_{3}$ supported y-alumina catalyst and $O_{3}$ molecule.
