  • This study focused on the anding of Inchon's identity The empirical method and ethnomethodological approaches were used to collect the data. Among members ofcitizen movement groups,government workers,and students who are living inInchon were selected as 613 samples using a purposive sampling method. MultipleClassification Analysis (MCA) and cross-tabulation methods were used in theanalysisThe study of identity in an area is important in terms of providing the solution ofthe problem in a region and social integration of the citizens. The scores of the indexabout Inchon's identity are quite low and more than half of the respondents to allthree groups showed the middle position of the scores from the identity index. By thecharacteristics of the respondents,female,unmarried single,30 years or more,lowerincome groups showed relatively higher identity index scores than other counter-parts . And professional,administrative,clerical workers'identity index scores werehigher than people who work at sales,service,and agricultural sectors. Respondentswith 2 years of college or more,with intentions to donate special monies for cultural, social welfare, environmental reform,persons who want to live in Inchon for along period of time equipped with a stronger identity index.For the character of Inchon's identity,there are no identity,making it fromnow on,capacity or broad-minded city,vanguard pioneer,displeased, Oiversity/multiplicity of the city,defense spirit from foreign invasion,entrancecity from the world in that order. Therefore,it is hard to say what exactly Inchon'simage is in a single word. However,Inchon can be characterized as a diverse citywith capacity to live together without any serious conflicts among citizens who come from Seoul,Kyunggi-Do,Chungchung-Do,Chunla-Do,Kyungsang-Do,and foreign countries including North Korea. These facts imply that Inchon should continue topursue this image as a diverse city with capacity as an identity pursuing towardsworld city and hub city of North East Asia.ty as an identity pursuing towardsworld city and hub city of North East Asia.

  • The characteristics of the flowfields around two circular cylinders in various arrangements were investigated by PIV. In tandem arrangement, the Strouhal numbers measured in the rear region of the cylinder of wake side were decreased with the space ratios, the flow between two cylinders was almost stagnated and the closer to upstream cylinder, the larger the width of the stagnated region was. The direction of vortex between two cylinders was opposed each other with the small difference(${\alpha}$=${\pm}1.0^{\circ}$) of the attack angle . In side by side arrangement, the flow velocity between two circular cylinders were increased with the space ratios.

  • In the fuel of the solid fuel ramjet there are metal particles in order to improve the Isp like as solid rocket propellants. Because of the short combustion residence time these metallized fuels have low combustion efficiencies. Therefore it is necessary to increase the combustion efficiency and the inlet air temperature does an important role to this. The main factors to affect the inlet air temperature is the free stream temperature and the flight Mach number. Also the flow velocity in the combustor does an important role, therefore entire range of the air flow; from the stagnation to the sonic velocity in the ramjet combustor is considered.

  • An experimental investigation of the flame appearance and heat transfer characteristics in both unexcited and excited impinging inverse diffusion flames with a loud speaker has been performed. The flame is found to become broader and shorter (in length) with acoustic excitation. The heat flux at the stagnation point is increased with the acoustic excitation. The acoustic excitation is more effective in lean conditions than in rich conditions. The reasons for these behaviors are that acoustic excitation improves the entrainment of surrounding air into the jet. From this study, it is found that the maximum increase of 57% in the total heat flux is obtained at the stagnation point of $\Phi$=0.8. Therefore, it is ascertained that the excitation combustion can be adopted with effective instruments as a method for improving heat transfer in impinging jet flames.

  • The number of allergic contact dermatitis patients is steadily increasing but a proper reliability treatment guide is not prepared in Oriental Medicine. Also, the number of clinical cases on allergic contact dermatitis is not sufficient in Oriental medicine. As such, the facial flushing of allergic contact dermatitis which has been improved by infra-red therapy is significant in its treatment purpose. We reported on 43-year old male patient with allergic contact dermatitis. We treated him with herbal concoction, acupuncture, infra-red therapy and cupping therapy. We have received a good result in this case by using the combination of infra-red therapy. We reached a conclusion that using infra-red therapy can improve the facial flushing of patient with allergic contact dermatitis. However, further research on the effect of infra-red therapy for these symptoms is desired.

  • This paper is to research the present conditions and characteristics of the machinery and metal industries in Busan region from industrial cluster and network point of view. The result of this study is as follows. First, a independent machinery and metal industrial cluster has been shaped in Busan region although it is not so large. Second, the technological level and the competitiveness of the machinery and metal industries in Busan region is still low. The companies in Busan area are interacted by local network with low-tech and low competitiveness. Third, we need to invite the technological leading companies to Busan region for this industrial cluster's technological competitiveness is raised.

  • 본 연구에서는 새벽과 오전에 비교적 흐렸음에도 불구하고 오존 주의보가 발령된 1999년 7월 18일을 대상으로 하여 고농도 오존의 발생에 대한 연구를 하였다. 부산 지역 3곳에서 동시에 1시간당 120ppb이상의 고농도는 11시 이후부터 15시에 걸쳐 구름이 엷어지면서 강하게 내리쬔 일사량에 의해 급격히 증가하여 생성된 것으로 나타났다. 특히 본 연구에서는 오전 9시나 10시경에 나타나는 혼합층 성장에 따른 상층의 고농도 오존의 연직혼합 현상은 없었던 것으로 보인다. 1999년 7월 18일의 고농도 오존은 공기가 정체한 상태에서 11시 이후의 강한 일사에 의한 광화학반응에 의해 1시간당 50ppb의 오존이 생성되는 고속생성에 의해 오존주의보가 발령된 것으로 판단된다. 따라서 향후 이러한 기상상태가 예상된다면 고농도 오존발생에 대한 경각심을 가지는 것이 현명하다고 본다.

  • 월드 와이드 웹(WWW)서비스는 상당한 지연이 발생할 것이라고 예상하는 수준까지 성장해 왔다. 이런 이유로 웹 지연시간을 줄이기 위한 기술들이 중요하게 되었다. 프록시 서버 캐시는 느린 응답시간과 네트워크 정체와 같은 문제들을 해결하기 위해서 제안되었는데 이런 프록시 서버들을 계층적으로 구성하는 방법에 대한 많은 연구가 있었다. 하지만 이런 일반적인 웹캐싱 계층 기법들은 프록시 서버들간의 통신 경로에 있어서 유연성을 제공하지 못하는 정적 구조의 기법이다. 이런 정적인 기법에서의 단점을 해결하기 위해서 캐싱 지역 프로토콜(Caching Neighborhood Protocol)이 제안되었고 이 CNP는 요청들을 협력적으로 처리하는 일련의 프록시 서버의 집합이 매 단일 요청에 대해서 바뀔 수 있고 이에 따라서 요청 처리 경로가 다양해 질 수 있기 때문에 정적 구조 기법과는 반대인 동적 구조 기법이다. 하지만 이러한 동적 웹 캐싱 계층 구조인 CNP에서는 각 웹서버를 대표하는 캐싱 대리인(Caching Representatives)에 대한 웹문서의 링크참조정보와 부하정보를 고려하지 않았기 때문에 사용자에게 빠른 응답시간을 제공하지 못하는 단점이 있다. 본 논문에서는 최근에 제안되었던 프록시 서버들을 동적 웹캐싱 계층으로 구성한 CNP와 새로 추가된 C-Rep의 상태정보를 이용해서 새로운 요청 라우팅 기법을 제안하였다. 제안한 기법은 이런 C-Rep의 상태정보를 이용하여 응답시간의 향상과 C-Rep의 부하를 분산시킬 수 있었다.
