The use of network planning models and tools is essential for effective KII (Korea Information Infrastructure) planning and analysis in that it will significantly reduce the risk and uncertainty embeded in the development and the provision of future broadband services. The purpose of this study is to develop a theoretical framework and a computer tool for modeling the various aspects of the KII topology and architecture and evaluating the techno-economic feasibility of the KII implementation strategy.

An intelligent road transport management system focused on microscopic, real-time traffic signal control is proposed. Referring to the development of those systems in Japan, extensive use of image traffic detectors observing the movement of vehicles inside intersections, and direct data exchange between the signal controllers of neighboring intersections are newly assumed. On site investigation of five intersections in Japan or in Malaysia shows the possibility of effective information provision and simple algorithm for solving heavy congestion, as well as easy installation.

본 연구는 SNS채널속성에 따라 검색의도가 구매행동에 미치는 관계를 분석하고자 SNS채널을 최근 1년 이내에 상품을 구매한 사용자를 대상으로 하여 구매행동을 설문조사하였다. 이를 바탕으로 분석한 연구결과는 SNS채널속성에서 정보제공성과 정보상호작용성은 검색의도에 영향을 주는 것으로 분석되었다. 그러나 정보의 신뢰성은 검색의도에 유의적인 영향을 주지 않는 것으로 분석되었다. SNS채널의 이용자를 통해 구매행동을 높이기 위해서는 정보신뢰성과 정보제공성도 주요시되고 있으나 그 보다도 더 중요한 것은 SNS채널 검색의도라고 볼 수 있다. 검색의도는 정보신뢰성과 정보제공성을 높이는 조절효과를 함으로 단순히 SNS채널의 속성을 높이는데 이어 정보제공성과 정보상호작용을 높여 검색의도를 높이는 것도 중요하다고 볼 수 있다.

The aim of this paper was to determine the utilization of online information resources by undergraduate students in the University of Nigeria, Nsukka. It was undertaken specifically with the objectives of identifying the online information resources used; academic purposes for their use, extent, problems and strategies for improving the academic use of the resources by undergraduate students. Descriptive survey was used as the research design. The population of this study comprises of all 25,657 regular registered undergraduate students in University of Nigeria, Nsukka. The sample for this study comprises 2500 students which is 10% of the population. The results of the study shows that most of the online information resources are not used by the undergraduate students. Just a few of them are highly used. Some of the academic purposes for the use of the resources include to do course assignment and project works and to stay up-to-date on social events. The major problems responsible for the low utilisation of the resources include incessant power failure, limited available computers in the university library, and server's low bandwidth. Based on the findings, maintenance of uninterrupted power supply, provision of enough computers in the library; constant upgrade of server's bandwidth and many more were recommended as the strategies for improving the use of online information resources by undergraduate students in UNN. The implication of this study lies in the fact that solutions to the problems raised would be helpful to the university management, librarians and students in ensuring maximum and adequate provision and effective utilisation of online information a resources in the library.

Purpose: Pain perception is affected by a wide range of contributing factors, including biological, psychological, and social factors. Although the provision of visual information could have a modulatory effect on pain perception, it is unclear whether such a visual effect might vary depending on the anatomical site and stimulation type. This study aimed to analyze the modulatory effect of visual information on the perception of sharp and dull pain in the face and hand and to assess the influence of individual fear levels on modulatory visual information. Methods: A total of 68 healthy male and female volunteers were recruited for this study. Pressure and pricking pain with and without visual information were induced on the masseter and thenar muscles, and alterations in pain threshold were evaluated. The survey was conducted using the Geop-Pain Questionnaire (GPQ). Results: The pricking pain threshold of the hand was significantly elevated when viewing the stimulated hand. This result indicated that the provision of visual information could decrease sensitivity to sharp pain in the hand. However, when correlating the GPQ score with the alteration in thresholds induced by visual information, no significant correlation was observed between the GPQ score and the threshold difference induced by visual information. This finding showed that the visual effect was not significantly affected by the fear level. Conclusions: This study showed that the effect of visual information on the pain threshold could vary according to the anatomical site and stimulation type. A better understanding of such a modulatory effect on pain perception might be useful for clinicians during painful therapeutic procedures.

This study comprehensively draws a conclusion using factors of economic, social, and educational value and performed a survey on librarians and users to compare and analyze the difference in perception between the two groups. The result are as follows: First, Libraries had the social value not only on research and personal learning but also on establishment and vitalization of communities, provision of opportunities to share ideas between local residents and create something new, and provision of recreation to improve the residents' capability. Second, both groups evaluated the libraries' educational role and function relatively highly. In particular, the librarians scored very high for the items that the libraries' educational role was expanding, the libraries were a part of the educational system, and the libraries' value on reading and literacy was great, and the users thought that libraries had an value because they were a part of education and the educational system. Third, economic value part also obtained relatively lower scores than other values; the mean of the librarian group was 3.46 and the user group was 3.43. Among the economic values, the librarian group scored the highest for the area of economic value for local communities, and the greatest scores were given to manpower development by the users.
