This study was intended to find the use patterns of internet search engines of librarians and to measure the relationship between internet use frequency and the use behavior of internet search engines. The results showed that librarians use Web search engines for academic information retrieval and are satisfied with the search results. The major problems when librarians use search engines were that search engines retrieve many non-relevant documents. As a result of hypotheses test, the relationship between internet frequency and the preference of search engines was not significantly different. On the other hand, the hypotheses that internet frequency affects satisfaction of search results, recognition of importance of search engines, and the need of retraining of librarians for internet information retrieval were shown to be significant.

Size of building has a direct relationship with building cost, energy use and space maintenance cost. Therefore, minimizing building size during a project development is of paramount importance against such wastes. However, incautious reduction of building size may result in crowded space, and therefore harms the functionality despite the fact that building is supposed to satisfactorily support users' activity. A well-balanced design solution is, therefore, needed at an optimum level that minimizes building size in tandem with providing sufficient space to maintain functionality. For such design, architects and engineers need to be informed accurate and reliable space-use information. We present in this paper a conceptual framework of an agent-based space-use prediction simulation system that provides individual level space-use information over time in a building in consideration of project specific user information and activity schedules, space preference, ad beavioural rules. The information will accordingly assist architects and engineers to optimize space of the building as appropriate.

국토공간의 이용상황을 파악하고 효과적인 개발 및 보존계획을 세우는 일은 국가의 중요 업무다. 그러나 60여개에 달하는 법률에 의해 조사가 이루어지고 있으나 조사대상, 방법, 시기 등이 달라 예산의 중복과 정책의 혼선을 야기하고 있다. 또한 공적장부에 기재된 지목은 공식적으로 토지이용 상태를 나타내고 있으나 현황에 따른 변경이 쉽지 않고 용도를 임의로 변경하여 사용하는 경우에는 이용현황의 종합적인 통계에도 오류가 발생하므로 일관된 방식의 조사와 정보구축이 필요하다. 본 연구에서는 토지뿐 아니라 공유수면과 지하공간까지 포함하는 국토공간에 대해 현행 이용현황조사를 분석하고 조사방법, 시스템구축, 법제도 개선, 정보활용을 위한 방안을 제시하였다. 결과적으로 정확하고 일관성있는 국토관리를 위해 지상 및 지하, 강, 바다 등에 대한 입체적인 현황 조사 및 관리가 필요하며, 이를 위한 법률 제정과 전담조사기관을 지정이 필요함을 알 수 있었다.

이 연구의 목적은 주요한 정보의 원천은 무엇이며, 정보 자원 관리에서 부딪치는 문제점을 파악하여 가능한 해결방안을 제시하는 것이다. 즉, 구체적으로 문자정보, 의사소통 그리고 정보활용기술을 통해 정보를 얻고 관리하는 데 있어 직위가 다른 경우 (책임자, 일반직원, 노조 대의원) 이 다른 원천들의 중요성을 얼마나 잘 알고 또한 인식하고 있으며 이 원천들에 대한 그들의 태도는 어떠한 가를 조사해 보려는 것이다. 연구의 결과 내부 정보 자원이 가장 중요하고 가장 많이 이용되고 있다. 정보 활용기술의 시설에 대해서는 가격은 저렴해지고 있는 반면 그 기능은 매우 향상됨에 따라 그 중요성이 증대되고 있으나, 그 사용은 쉬운 것에 제한 되고있어 경영자는 효율적 사용을 극대화 하기 위해서는 좀더 많은 관심과 철저한 교육 훈련이 있어야 함을 제시하고 있다.

The purpose of this study were (1) to segment the female college students according to apparel shopping orientation and (2) to create a profile for each group with regard to impotance of store attributes, use of information sources, and self-image. The questionnaire were administered to the female college students living in Seoul and data were analyzed by frequency, percentage, factor analysis, cluster analysis, one-way ANOVA(analysis of variance), and MANOVA(multivariate analysis of variance). By cluster analysis of apparel shopping orientation factors, four groups are identified : (1) highly involved apparel shopper (44.34%), (2) brand-loyal shopper (24.43%), (3) planned / practical shopper, and (4) apathetic shopper (18.10%) Four groups were then compared through MANOVA on importance of store attributes, use of information, and self-image. Significant differences were found among four groups on three variables. In general. highly involved shopper tend not to be price conscious, enjoy shopping and use the information sources most actively and apathetic shoppers tend to be indifferent to apparel shopping and do not actively use the information sources.

It has been argued that Enterprise systems (ES) implementations are overshadowed by a high failure rate despite their promised benefits. One of the commonly cited reasons for ES implementation failures in the context of mandatory use is end-user's unwillingness or sabotage to adopt or use systems. Considering that the appropriate management of expectations may play an important role in making positive behavior toward newly implemented systems, this study examines the effect of outcome expectations on the system use activity in the mandatory use context of information systems from the Social Cognitive Theory perspective. Structural equation model analysis using LISREL 8.7 provides significant support for the proposed relationships. The empirical results suggest that outcome expectations and user satisfaction have positive effects on system use activity conceptualized by immersion, reinvention, and learning. Theoretical and practical implications of the study shed some light on how to improve system use activity in the mandatory use context of information systems.

There has been an upward trend in smartphone sales in Korea as well as the rest of the world. Even though smartphones are now at the peak of their popularity, the fact that they are somewhat limited in terms of their usages for certain purposes is unexpected. Precisely, compared to PC, smartphones typically have smaller display screens with a lower resolution, which make them difficult to use in general. For instance, when customers search the information about products in mobile shopping malls, due to the smaller screen with a low resolution smartphone users may realize that it is not easy and convenient not only to search the information, but also to read the information they found in the shopping malls. This restriction could become one of reasons that lowers the perceived quality of information in the shopping malls, which in turn leads to the reluctance to use the shopping malls. A comprehensive information systems (IS) literature review found that there has been little empirical evidence on perceived information quality that affects smartphone users' intention to use mobile shopping malls. The purposes of this study is to examine 1) the effects of perceived information quality on smartphone users' intention to use mobile shopping malls and 2) the relationships among behavioral beliefs in the middle of independent and dependent variables, such as information satisfaction, perceived usefulness, and customers' attitude toward mobile shopping. A survey was conducted in March 2012. College students and practitioners took participated in the survey. Structural Equation Modeling(SEM) was used for all data analysis. The results found that there is a strong relationship between perceived information quality and smartphone users' intention to use mobile shopping malls. In addition, this study also showed that there are strong relationships among behavioral beliefs. Further research is expected to validate the findings of this study and apply them in specific contexts.

Planning Support System (PSS), an alternative framework of computer-aided planning system combining geographic information system (GIS), urban models, and visualization tools, has been actively researched and applied in many developed countries. This paper introduces a PSS-based land use change model, What if\ulcorner PSS, by applying it to Chongju City, Korea. This model application study used the spatial database, Restricted Development Zone (RDZ), and other hypothetical land supply- and demand-related policies of Chongju City. The collaborative PSS model supported land use planning process by helping users to speedily and easily create and test policy-oriented scenarios. The study found that the fully operational PSS model was readily applicable and useful to Korean local land use planning. The paper discusses the conceptual model framework, data requirement, application process, model output, and practical usage. This study would be considered as a prototypical approach of PSS-based land use plan making for Korean cities.
