This study was tried for revitalization of the traditional markets, at which were located the same business district of grand supermarket of an urban area in Seoul. The Myung-Il Market, one of traditional markets near the Gang-Dong Homeplus was selected for this research. In our research including the survey from the 63 purchasers' samples of Myung-Il traditional Market, the policy to strengthen the traditional market's ability was suggested to use the price and hygiene factors which affecting on the customers' satisfaction significantly. And the other complementary stategic factors, service and geographical area factors, were induced which were significantly relating to the 100 samples of purchasers at Gang-Dong Homeplus as the grand modern market. Therefore this research suggests the maintaining and enhancement strategy related to price and the hygiene factors should be impressed on the preferential basis for revitalization the traditional markets. And the other strategy which including service and geographical area factors as from the grand modern market's survey result will be considerated complementarily.

Due to the phenomenal growth in mobile internet users, mobile business as a type of applications of mobile internet has attracted the related industries' and academic researchers' attentions. However, most researchers focus on the issues of Mobile B2C collecting survey questions from consumers or internet users. This paper points out that Mobile B2B has distinct service sector and analyzes the current trend and demand of Mobile B2B in Korea by collecting survey questionnaire from specialists in mobile industries and people in universities and research institutes. Survey fields include business, market, contents/application, research and development and legal system. According to the survey results, Mobile B2B business will rise in distribution, finance, sales, and logistics industries from the beginning of 2005 using wireless PDA and the important preconditions will be security, certification, and standardization.

In these days, such services are popularized as E-commerce, E- government, multimedia services, and home networking applications. Most web traffics generated contemporarily basically use the Hyper Text Transfer Protocol(HTTP). Unfortunately, the HTTP is improper for these applications that comprise significant components of the web traffics. In this paper, we introduce a real-time contents compression architecture that maximizes the web service performance as well as reduces the response time. This architecture is built into the linux kernel-based web accelerating module. It guarantees not only the freshness of compressed contents but also the minimum time delay using an server-state adaptive algorithm, which can determine whether the server sends the compressed message considering the consumption of sewer resources when heavy requests reach the web server. Also, We minimize the CPU overhead of the web server by exclusively implementing the compression kernel-thread. The testing results validates that this architecture saves the bandwidth of the web server and that elapsed time improvement is dramatic.

Smart phones that have lost their existing physical home buttons are being released at the same time, and the flow of users is also changing. The flow is highly subjective and can vary depending on the individual's tendencies. Therefore, this study investigated the change of the flow of smart phone users by Q methodology which is a method of subjectivity research. As a result, the proficiency level of how to turn on the power to start the screen showed a tendency to decrease the flow, and the playability, which is a result of curiosity about the new thing, The results were very positive in the continuity of navigation due to the use of software buttons instead of buttons. Therefore, it can be seen that the change in the hardware smartphone has a positive effect on the flow.

This paper analyzed the circularly polarized conformal microstrip patch antennal using the unsplit anisotropic perfectly matched layer(UAPML) method. Also, this paper are treated effectively the edge and corner parts on the 3 dimensional UAPML. Especially, to analyze microstrip patch antennas with the coaxial feeder line, it was applied to mixed the UAPML with Mur's first order absorbing boundary condition. Therefore this paper suggest the new the method to mix the UAPML with Mur's first order absorbing boundary condition. The results show the time responses of electromagnetics $E_z$ and $H\chi'$, input impedances of coaxial cable and radiation patterns of strip parchs on the single and the array patchs with central frequencies 1.575 GHz, 1.778 GHz and 4.8 GHz in L-band and C-band for mobile communication. The results of this paper shows that its results was compared the Mur's first order abc and mixed the second order dispersion boundary condition(SDBC) with the Mur's first order absorbing boundary condition. In accordance with, the validity of the method is confirmed.

본 연구의 목적은 한국에서 장래에 이루어질 노인주거연구의 주제를 예측할 수 있도록 일본, 미국, 한국의 노인주거연구의 경향의 차이를 파악하고 비교하기 위한 것이다. 본 연구는 세나라에서 1940년대부터 1990년대 현대까지 발표된 노인주거연구에 대한 학술지와 논문을 분석함으로써 이루어졌다. 세 나라에서 전체 772편의 논문을 수집하여 이를 발표된 연도와 주제에 따라 분류하였다. 본 연구는 일본과 미국의 연구 경향의 특징을 별도로 발표한 후속 연구이다. 일본에서는 1950년대에 노인주거에 대한 연구가 시작되어 80년대 후반에 절정을 이루었으며, 그 이후로 서서히 관심이 줄어들고 있는 추세이다. 일본에서의 주요 주제는 노인홈과 노인시설내의 주 생활조사, 3대 동거 주택, 유료노인홈과 노인시설의 소비자 문제등이다. 미국의 경우, 노인주거의 연구는 일본보다 빠른 1940년대에 시작되어 70년대와 80년대에 걸쳐서 다른 때보다 더 많은 연구가 발표되었다. 주요주제는 1970년대부터 80년대에는 노인주거와 노인시설에 집중되어 있었으나 80년대 이후에 노인주거의 연구방법과 노인주택정책방향으로 관심이 바뀌고 있다. 한국에서의 노인주거에 대한 연구는 세나라 중에서 가장 늦은, 1970년대 후반부터 시작되어 80년대 후반 이래로 그 관심이 점점 증가하고 있다. 한국에서 가장 관심이 있는 연구대상의 하나는 일본과 마찬가지로 기혼자녀와 노부모와의 동거주택에 대한 주제이다. 이상 세나라의 연구주제에서의 차이점은, 한국과 일본에서는 모두 노인주거와 연구방법 분야에는 비교적 관심이 적은 반면, 미국에서는 3대동거주택에 대한 관심이 적은 것이다. 일본과 미국 두나라에 비하여 한국에서는 노인주거 연구에 있어서 아직까지 다양한 주제를 발견하기 어려운데 그 이유는 한국에서는 노인주거에 대한 구체적인 개발이 아직까지 이루어지지 않아서 노인주거에 대한 경험도 많지 않기 때문이라고 생각된다. 앞으로 한국에서도 노인주거가 개발된다면 그 후에는 보다 다양한 연구주제가 나타날 것이라고 기대된다. 예를 들면 노인거주시설의 질적인 비교, 특수한 형태의 노인주거에 대한 요구, 노인주거내의 주생활조사나 평가, 노인을 위한 설비의 디자인 등에 관한 연구들을 생각해 볼 수 있다.

정부는 최근 그린홈 100만호 사업을 중심으로 각종 신재생에너지 보급률 향상을 도모하는 많은 프로그램을 기획하여 현재 약 12개의 신재생 에너지 보급지원 프로그램과 R&D 프로그램을 운영하고 있다. 그러나 현재 국내 신재생에너지 정책 및 프로그램은 차후 개선 및 체계적인 운영을 위한 조직적인 프로그램 평가 체계를 갖추고 있지 않으며 평가 기관이나 평가 주기 등 평가에 필요한 기본적인 합의와 법제적 배경 역시 미비한 상황으로 신재생에너지 프로그램의 평가 제반 시스템에 대한 근본적 고민이 필요한 시점이라고 볼 수 있다. 이에 본 연구에서는 미국 DOE(Department of Energy)산하 EERE(Energy Efficiency & Renewable Energy)의 신재생에너지 보급사업평가체계를 분석하여 EERE 프로그램 평가 방법의 국내 적용 가능성을 검토해 보았다. EERE는 미국의 에너지 효율화 및 신재생에너지 전담 사무국으로 10개의 에너지효율화 및 신재생에너지 연방정부 프로그램을 운영하고 있으며 Strategic Management system을 통해 효율적인 프로그램 관리를 시도하고 있다. 특히 General program evaluation Guideline에서는 표준화된 세부 평가 방법론을 제시하여 정례적 혹은 일회적 평가를 시행하고 있는데 이 세부 평가 방법들은 프로그램의 특성에 따라 프로그램을 운영하고 프로그램의 존속 및 개선여부를 결정하는데 결정적인 도움을 주고 있어 차후 국내에서 시행되고 있는 신재생에너지 프로그램의 정성적/정량적인 평가를 시행하는 많은 시사점을 제공할 것으로 기대된다.
