This study intends to develop web-based information literacy program, analyze learning effects and to suggest a model case to those who wants to develop a web-based information literacy program in the future. For this purpose, we analyze undergraduate students' needs, design and develop a web-based information literacy program, and analyze the practical effects of the web-based information literacy program. As a result of research, we found out that both web-based and face-to-face information literacy program are similarly effective in learning and satisfactory to students.

In this research, several ways of creating effective STI(Scientific ＆ Technological Information) databases were suggested. We put emphasis on the selection of input data, while on the other was handled, such factors as standardization for data entry, data entry system, etc.. In order to decide priority of target data, the status of document delivery service was analyzed. The result shows that conference proceedings were given priority to academic journals. In case of journals, ranking in the number of documents requested at KORDIC (Korea R＆D Information Center) and 16 Specialized Information Centers was compared with the ranking in citation frequency and impact factor, appeared at SCI.

The purpose of this study is to propose new menu structure and terms to be used by Website design for utilization of academic library Website. The menu structure was analyzed, based on seven menu patterns of Website which is widely used, and terms were analyzed by the frequency appearing at the Website. According to the analyzed result, the menu structure used to more than two menu patterns and the terms appear variety. The profitable menu pattern appears 〈table〉 and 〈frame + table〉 menu structures and the terms needs to systematic re-classification and controlled presentation. It is expected that this study can help a designer to the development and implementation of efficient Website. It helps not only to solve the problem of menu structure and term selection for librarian, but get rid of confusion of library services for users.

This study analyzed 138 multicultural programs from 40 libraries during the last two years. The study compares multicultural programs running in Korean libraries with those from American and Canadian libraries which have a long history of multicultural societies. The results are listed below. There is a need for long-running multicultural programs that address the needs of its users even from the planning stages. Programs should include out-reach based running methods, daily life based subjects and contents, and differentiated approaches for different levels and ages of users.

Recently, the rankings of Korean container ports in terms of container handling cargo volume were plunged down due to the emerging Chinese ports. The efficient container ports strategies which increase container port competitiveness were requested. In this respect, it is urgently required to draw out constituent factors for Port Logistics, weigh these factors, and finally focus on improving the suggested factors. The aim of this paper is to evaluate weight and priority values for 'inner consisted factors' and 'outer requested factors' of port logistics by using the AHP(Analytic Hierarchy Process) method. As for the analysis regarding the inner consisted factors, the results were shown as follows: a storage and handling system (0.288) as the first rank; an information system of port logistics (0.210) as the second rank; an inland intermodal system (0.189) as the third rank; a ship's entering and departuring system (0.184) as the fourth rank, and a ship's berthing system (0.129) as the fifth rank. In terms of analysis regarding outer requested factors, the results came out as follows: a logistics cost (0.360) as the first rank; a port service (0.128) as the second rank; a connectivity (0.118) as the third rank; a hinterland condition (0.116) as the fourth rank; an convenience (0.106) as the fifth rank; a regional center (0.095) as the sixth rank, and an availability (0.077) as the seventh rank. For analyzing the priorities changes in constituent factors, the comparison of results between the year 2007 and the year 2011 was done. As the results, among inner consisted factors, 'information system of port logistics' was ranked first in the year 2007 while 'a storage and handling system' became the most important factor in the year 2011. Among the inner consisted factors, however, the logistics cost was the important factor in 2007 and 2011, respectively.

There is a recognition that traditional resource sharing methods such as interlibrary lending and document delivery are now inadequate to meet user needs in the increasingly networked environment. The current study identifies barriers to resource sharing and provides analysis of stakeholders engaged in resource sharing. Focused interviews with six professional librarians were also carried out to seek out deeper understanding of perceptions of barriers among librarians. Results show that the size of the library was not necessarily result in active resource sharing. There was a wide gap among librarians in terms of their attitudinal and organizational orientations towards resource sharing. Barriers specifically identified in the study include the narrowly defined notion among librarians of what constitutes research and the untested fear of swamping where there is an imbalance of collections. Overall, while resource sharing is recognized as an integral part of library services, it seriously lacks funding and staff. The study recommends earnest efforts to build librarians' community to invigorate resource sharing among libraries.

Android-based smartphones receive the global navigation satellite system (GNSS) signals to determine their location and provide the GNSS raw measurement to users. The available GNSS signals on the current Android devices are GPS, GLONASS, Galileo, BeiDou, QZSS. This research has analyzed the performance of multi-GNSS position accuracy based on the pseudorange of the smartphone for maritime users. Smartphones capable of receiving dual-frequency are installed on a ship, and multi-GNSS raw information in maritime environment was measured to present the results of comparing the GNSS pseudorange-based dual-frequency positioning performance for each smarphone. Furthermore, we analyzed whether the results of the positioning performance can meet the HEA requirement of IMO for maritime navigation users. As the results of maritime experiment, it was confirmed that in the case of the smartphones supporting the dual-frequency, the position accuracy within 6 meters (95%) could be obtained, and the HEA position accuracy performance within 10 meters (95%) required by IMO could be achieved.

This study was conducted with 50 elderly people each (5) participating in the cognitive rehabilitation treatment program at the Dementia Care Center in D City to derive the development direction and contents of a multidimensional therapeutic recreation program and a revitalization plan through analysis of the current status and actual conditions of the cognitive rehabilitation program at the Dementia Care Center. aperture) was selected, and 9 people were selected as the subject of expert group opinion collection. The collected data was SPSS ver. Using the 18.0 statistical program, descriptive statistics and the importance and priority of each component were analyzed by hierarchical structure analysis. First, unlike the needs of users, the cognitive rehabilitation support programs currently being provided are not sufficient and require considerable experience. It was found to be low, and the areas for improvement were the expansion of care and protection facilities and the development of various programs to meet the needs of users. Second, the importance and priority of each component of therapeutic recreation were categorized into 6 major categories: exercise therapy , middle category (16 items) behavior-centered approach to exercise therapy, small category (47 items) strength and brain gymnastics, and silver health gymnastics were the highest. This result shows that a multidimensional program plan that considers the priorities of each area must be made when developing a therapeutic recreation program.

일본 총무성은 2010년 6월 30일 SIM 잠금해제에 대한 가이드라인을 발표하여, SIM 잠금 정책을 구제화 하였다. 이를 통해 2011년 4월 이후 출시되는 단말부터 이동전화사업자는 이용자의 요구가 있는 경우 SIM 잠금을 해제해야 한다. 이것은 지금까지의 갈라파고스 신드롬으로 불리는 기술 국수주의를 극복하고, 이동통신소비자들의 선택권을 확대하는 동시에 통신사업자들의 시장경쟁을 활성화하기 위한 조치의 일환으로 볼 수 있다. 그러나 NIT 도코모와 KDDI는 총무성의 SIM 잠금해제 정책에 긍정적인 입장을 취하는 반면, 소프트뱅크 모바일은 자사의 아이폰 가입자를 도코모로 유인하려는 의도로 생각하여 반대의 입장을 표명하고 있어 총무성의 SIM 잠금 해제 정책이 일본의 이동통신시장에 미치는 효과가 어느 정도일지는 지속적으로 지켜볼 필요가 있다.
