In SCADA systems, an RTU is a device installed at a remote location that collects data, codes the data into a format that is transmittable and transmits the data back to a central station, or MTU. An RTU also collects information from the master device and implements processes that are directed by master device. RTUs are equipped with input channels for sensing or metering, output channels for control, indication or alarms and a communications port. In general, the data are transmitted via a wired communication infrastructure such as RS422 or RS485 between RTU and MTU. But, limited range of wired communication doesn't allow the system to cover remote areas over the limitation, and building a wired communication network is not easy in the circumstances. In this Paper, we design and implement a smart cost-effective Web-RTU that can communicate with MTU via Web. Web is of benefit to the Web-RTU, because it is not only free from the distance limitations, but also is built easily and cost-effectively wherever Internet resources are available. Additionally, Web can be easily applied to the SCADA system with the development of hardware and software for communications. The Web-RTU has a program memory, a data memory and a RAM inside, and uses Atmega128, low-cost 8 bit micro-processor with eight AI(Analog Input). It performs well enough to implement all existing roles of RTU.

The main purpose of this study is to find the factors affecting the consumer goods buyers' choice on e-commerce sites in Vietnam. By using the quantitative method, the paper examines the theoretical research model and tests four hypotheses. The sample was drawn from the population of e-commerce sites in Vietnam comprising about 1,000 respondents. This study used the questionnaire method to collect primary data to test the hypotheses. Data analysis of the questionnaire was done using SPSS. The results show that there is a correlation between personal preferences of consumers on colors and brands and their actual final choice on e-commerce sites in Vietnam. The most important factor affecting the consumer goods buyers' choice on e-commerce in Vietnam is the brand of E-commerce site, following by the color and position. Among all educational groups, respondents with a Master degree pay the biggest attention to the site's color attribute, and those with a Bachelor degree pay more attention to the brand attribute. Women pay much more attention to the location of the products on the screen than men, as do consumers with a PhD degree, over respondents with a Bachelor or Master degree, and foreigners over Vietnamese consumers.

The development of the Surrey Research Park by the University of Surrey is an addition to a number of existing strategies to collaborate with industry that it has developed over its 120 year history. The potential to undertake this development was based on owning a substantial land holding that the University acquired when the Borough Council for the town of Guildford invited the University to relocate from Battersea in London to its new location in 1966. Initial plans for the Park in 1979 were accelerated in 1981 in response to plans by the then government to reduce funding for Higher Education in the UK. Beyond a broad master plan for the site that was based on topography and access to the site the plans that were developed were based on a survey of 100 companies that were deemed to be in the target market for the site and a review of the other 7 science parks that were being developed in the UK in 1981. The findings from this proved to be important in developing the master plan for the site. Another important influence on the project was the objectives that were defined for the 3 stakeholders in the project of the University, the tenant companies and the planning authority relate to economic development, a competitive advantage of tenant companies, knowledge transfer, the profile for the University and the capacity to generate income proved to be a valuable framework on which to develop a master plan. These details were underpinned by five objectives which served the three stakeholders in the site. Those for the University included commercial potential, knowledge transfer and image and reputation; those for the town primarily related to economic development and the plan was to help tenants gain a competitive advantage by locating on the site. In addition a number of success indicators were defined for the project against which to measure performance and have remained as a useful set of parameters on which to base the assessment of the performance of the site. In combination with these indicators a further analysis deals with the success factors that are considered as important in influencing performance. The paper sets details the history of the park and covers the success indicators and factors and reviews these in the context of the original objectives for the site.

본 연구에서는 몽골에 성공적으로 진출한 우리나라 유통기업인 CU의 사례를 통해 몽골 소매유통시장의 특성을 살펴보고, 몽골에 진출하려는 한국 기업에게 유용한 시사점을 제시하였다. 지금까지 몽골은 한국과 지리적으로 인접해 있음에도 불구하고, 작은 내수시장과 내륙국가라는 지리적 위치, 비효율적인 물류 인프라 및 유통산업과 관련된 법과 제도의 미비로 인해 소매유통업이 발전하기 어려운 환경을 가지고 있다고 알려져 있었다. 그러나 CU는 몽골 현지 기업과 마스터 프랜차이즈 계약을 활용하고, 글로컬라이제이션 전략을 추진함으로써 몽골 시장에 성공적으로 정착하였다. 몽골 CU는 단순한 편의점이 아니라 몽골인들이 글로벌 문화를 향유하고, 자신들의 소비 욕구를 충족시킬 수 있는 새로운 공간으로 재구성되고 있다.

주파수 상황에 대해 정확히 인지하는 기법은 사용되고 있지 않은 주파수를 활용하는 인지 라디오 시스템에서 중요한 연구 과제 중 하나이다. 본 논문에서는 인지 라디오 ad hoc 네트워크에서 주파수 상황인지 능력을 향상시키기 위한 감지(sensing) 채널 선택 기법을 제안한다. 제안하는 기법은 각 인지 라디오 사용자가 감지한 정보를 활용함으로써 협동 감지를 실현할 수 있도록, 마스터(master)를 가지는 일종의 클러스터(Cluster)를 이루어 채널 상황 정보를 수집/분석한다. 특히, 라이센스를 가진 사용자의 전송 반경이 한정되어 있다는 점을 활용하여 인지 라디오 사용자들이 각기 다른 주파수 대역을 감지하게 함으로써 좀 더 빠르고 정확하게 주파수 대역의 상황을 인지한다. 제안하는 기법의 성능을 시뮬레이션을 통해 평가하고 마스터 없이 개별적으로 주파수 상황을 인지하는 기법과 클러스터를 이루되 공간적으로 채널이 비어있을 수 있다는 점을 활용하지 않는 기법과 성능을 비교하였다. 시뮬레이션 결과 제안하는 기법이 많은 빈 채널을 확보하면서도 빠른 시간 내에 라이센스 사용자를 발견함으로써 라이센스 사용자와 인지 라디오 사용자의 요구를 동시에 만족시킬 수 있음을 보였다.

최근 이동체의 위치 데이타를 활용한 위치 기반 서비스에 대한 관심이 높아지면서, 보다 효율적인 이동체 위치 데이타 관리 시스템으로 클러스터 기반 분산 컴퓨팅 구조인 GALIS(Gracefully Aging Location Information System)가 제시되었다. 그러나 GALIS의 서브 시스템인 SLDS(Short-term Location Data Subsystem)는 다수의 SDP(Short-term Data Processor) 노드들이 처리한 질의 결과를 SDP 마스터에서 취합하여 클라이언트로 보내는 구조이기 때문에 SDP 마스터에 장애가 발생할 경우 서비스가 중지되고, SDP 마스터에 부하가 집중될 경우 클라이언트로의 응답 시간이 길어지는 문제가 있다. 따라서, 본 논문에서는 기존 SLDS에 이중화를 지원하기 위해 SDP 마스터를 추가하여 기존 SLDS의 안정성을 높이고 이동체 위치 데이타의 질의 처리 성능을 향상시킨 확장 SLDS를 설계 및 구현하였다. 확장 SLDS에서는 두 대의 SDP 마스터를 가동함으로써 한 SDP 마스터에 장애가 발생하더라도 다른 SDP 마스터가 서비스를 계속 제공함으로써 시스템의 안정성을 보장한다. 또한, 확장 SLDS는 두 대의 SDP 마스터가 질의 처리를 분산하여 수행하기 때문에 클라이언트로의 응답 시간을 줄일 수 있다. 마지막으로 확장 SLDS의 장애 테스트와 질의 처리 성능을 실험하였으며, 이러한 실험을 통해 확장 SLDS의 고신뢰성 및 고가용성을 검증하였다.

Objectives : To understand the current status of the opening, closing and relocation of primary medical institutes in Korea and identify the underlying decision factors. Methods : Sources of analyzed data included the medical institutional master file at the National Health Insurance Corporation(1998, 2000) and Regional Statistic Annual Bulletins. To investigate changes including the opening, closing and relocation, a total of primary medicalinstitutions(16,757 in 1998, 19,267 in 2000) were analysed. Results : Between 1998 and 2000, there was a 15.0%(2,510) increase in the number of primary medical institutions and the rate of increase in the rural area was higher than the urban area, and higher for specialty clinics than primary practice. However, these findings did not suggestany improvement in the maldistribution of primary medical institutions. During the time period studied, newly opened and closed primary medical institutions numbered 4,085 and 1,573, respectively. Additionally, institutions thatrelocated numbered 2,729, or 16.3% of all primary medical institutions in operation in 1998. These openings and closings were more frequent among young doctors. As a result of our analysis on the underlying regional factors forrelocation, the factors that were statistically significant were local per capita tax burden and the number of schools per ten thousand persons. !n, the case of institutional factors, movements were significantly associated with gender and the location of primary medical institutions. Conclusions : In order to establish effective long-term intervention for primary medical institutions, further study and monitoring of primary medical institutions and the identification of factors influencing opening location and relocation is necessary.

This landscape design proposal was presented to a design competition for the master plan of Ttukseom Sup, which was held by the City of Seoul in March, 2003. The site is located at 1-685, Sungsu-dong, Sung-dong-gu and has an area of 1,156,498$m^2$. The judging criteria for landscape design set by the City of Seoul could be articulated as follows: first, the proposal should be nature-oriented with groves that can be accessed easily by citizens; second, the proposal should not be facilities-oriented but plants-oriented groves that utilize existing plants; third, the proposal should present its own identity reflecting its historical aspects and geographical location. This proposal has been approached first by redefining the meanings of the old Korean village groves and second, by proposing new cultural infrastructures with the groves corresponding to recent cultural trends.
