대학도서관의 정보기술 환경과 이용자의 정보기술 이용능력이 도서관 이용행태에 어떠한 영향을 미치는가를 규명하고자 한다. 본 연구는 독립변인으로 선정된 도서관 집단간의 비교와 이용자 집단간의 비교를 통한 비교실험을 실시하였다. 연구결과, 대학도서관의 정보기술 환경에 따른 도서관 정보기술 이용행태는 대체적으로 차이가 없으며 개인의 정보기술 이용능력에 따른 도서관 정보기술 이용행태는 차이가 있는 것으로 나타났다.

This study aimed to quantitatively analyze the trends in environmental research that utilize environmental geospatial information through text mining, one of the big data analysis technologies. The analysis was conducted on a total of 869 papers published in the Republic of Korea, which were collected from the National Digital Science Library (NDSL). On the basis of the classification scheme, the keywords extracted from the papers were recategorized into 10 environmental fields including "general environment", "climate", "air quality", and 20 environmental geospatial information fields including "satellite image", "numerical map", and "disaster". With the recategorized keywords, their frequency levels and time series changes in the collected papers were analyzed, as well as the association rules between keywords. First, the results of frequency analysis showed that "general environment"(40.85%) and "satellite image"(24.87%) had the highest frequency levels among environmental fields and environmental geospatial information fields, respectively. Second, the results of the time series analysis on environmental fields showed that the share of "climate" between 1996 and 2000 was high, but since 2001, that of "general environment" has increased. In terms of environmental geospatial information fields, the demand for "satellite image" was highest throughout the period analyzed, and its utilization share has also gradually increased. Third, a total of 80 correlation rules were generated for environmental fields and environmental geospatial information fields. Among environmental fields, "general environment" generated the highest number of correlation rules (17) with environmental geospatial information fields such as "satellite image" and "digital map".

Environmental impact assessment is a regulation that is implemented to reduce harmful environmental impacts of development projects. However, The environmental value is difficult to quantify and the uncertainty, There is a problem of objectivity and reliability of the system is consistently pointed out. Therefore, the necessity of the data-based environmental impact assessment system is gradually increasing. Especially, environmental impact assessment is highly applicable to environmental spatial information because it contains about the development of a particular area. Also with the introduction of EIA Follow-up management system, there is a demand for a system for providing and utilizing environmental information in a time series. This study derives the necessity of information provision system and analyz existing environmental information utilization system based on the institutional characteristics of environmental impact assessment. And suggest ways to provide environmental spatial information to find policy implications for improving the limit of environmental impact assessment system.

클래스에 관한 재사용 관련 정보는 기능.환경면에서 정보와 품질 메트릭 정보로 구분할 수 있다. 기능.환경면에서 정보는 재사용 부품의 기능과 구현 환경에 관한 정보이며, 품질메트릭 정보는 재상용 부품들의 재사용성을 가시적으로 측정할 수 있는 정보이다. 클래스의 재사용성을 측정하기 위해서는 클래스의 절차적이고 객체지향적인 특성들을 모두 고려하여야 한다. 그러므로 본 논문에서는 클래스에 관한 재사용성 관련 정보를 소개하고 품질 메트릭 정보를 정량화시키는 정의식들을 제안하고, 클래스 코드로부터 기능.환경면으로 정보와 품질 메트릭 정보를 추출 및 측정하였다

In conventional game systems, virtual environments usually have just the role of a background without the direct relationships for game characters. nev do not consider the semantics about virtual environments. In this paper, we develop a game navigation system that provides semantic information about virtual environments including geographical, historical or my other location-dependent information. Then, the game character obtains the geographical location and its related information when it navigates through a virtual environment. It can be an implementation method for a semantic virtual environment because it can have the environment maintain its semantics depending on the specific location. In addition, we describe a method that can control a character's motion in the semantic virtual environment interactively, and that can input specific information according to the location of the character.

The purpose of this study is to analyze user needs of university libraries for design of user-centered information retrieval system. To do this, 6 kinds of basic system design factors necessary for user-centered information retrieval system design of the university libraries are used. The user needs which should be considered for system design are examined and analyzed through the questionnaires made by user-centered approach according to the design factors.
