This study aims to investigate the relationship between university library usage and educational achievement of academic library users. To proceed with this study, academic library usage data were collected from S university undergraduate students. Academic achievement was measured using the students' grade point average(GPA). T-test and analysis of variance were used to compare differences of means between library usage and academic achievement with the background variables. Hierarchical regression analyses were conducted to determine the association between library usage and academic achievement. As a result, a positive correlation was found between academic achievement and the use of library resources and services according to gender, year and academic subject. In addition, academic library usage had a positive significant influence on academic achievement. Students who used more library resources and facilities ultimately get better grades.

벤처 기업의 평가와 관련되어 벤처 캐피탈리스트들의 의사결정에 대한 지금까지의 선행 연구들의 주 초점은 벤처 캐피탈의 의사 결정 과정과 이에 관련된 의사 결정 기준이지만, 연구의 또 다른 상호 보완적인 흐름은 의사 결정에 상대적인 가중치와 중요성에 영향을 주는 요인에 관한 것이다. 즉, 벤처 캐피탈리스트의 의사결정에 있어서 인적 자본 요소인 벤처 기업의 창업자 또는 창업팀의 특징이 더 중요하다는 주장과 불확실성을 특징으로 하는 제품/서비스의 특징, 시장/산업의 특징, 재정적 특징이 창업자/창업팀의 특징 보다 더 중요하다는 두 가지 관점이 선행 연구에 존재한다. 그러나 벤처 캐피탈리스트의 의사 결정에 영향을 주는 것으로 알려진 두 가지 주장은 각각 독립적으로 연구되어 왔기 때문에 창업자의 특징과 불확실성의 요소가 결합된 상호 영향이나 상대적인 중요도가 벤처개피탈의 의사결정에 어떤 영향을 주는지에 관한 연구는 거의 없다. 이러한 배경에서 본 논문의 목적은 인적 자본 이론을 도입하여 벤처 캐피탈리스트의 의사 결정에 중요한 의사 결정 기준인 창업자의 특징 중 창업자의 경험(산업 경험, 창업 경험, 경영 경험)과 불확실성으로 발생되는 요인의 상대적인 중요도에 대한 이해를 증진시키는 것이다. 본 연구에서는 창업자의 특성과 불확실성의 특성을 벤처 캐피탈리스트의 의사 결정 과정에 실험적으로 적용할 수 있는 가상의 시나리오를 기반으로 하는 컨조인트 분석법을 적용하여 창업자의 특성과 불확실성을 포함하고 있는 8가지 요인(속성)의 중요도를 연구한다.

When measuring the value of environmental attributes of housing, the conventional Hedonic Pricing Method assumes market equilibrium. Thus each attribute is believed to be implicitly valued based on the market price. The revealed preference is the basic logic in this approach. However, if the participants in the housing market are not perfectly informed or feel vagueness regarding the attributes of the housing, the conventional Hedonic Pricing Approach could not provide relevant value of the attribute in question. A Fuzzy Regression Method is suggested to handle with the lack of information or preference uncertainty problem m the Hedonic Pricing Approach. In this paper, our main concern IS given to the fuzziness effect on the airport noise in the metropolitan areas of South Korea.

The purpose of this study is to Investigate the factors haying an Influence on activating the Interlibrary loan between national university libraries. Data were collected by and questionnaires. To analyze the factors activating the Interlibrary loan, 1-test and regression analysis method Is adopted depending on the type of data collected. The findings of the study shows that the interlibrary loan can be more actively performed in the group of libraries to focus the subject background on library and Information science than the other group the number of lending cases is highly affected by collection size. the number of periodical titles, annually increased number of collections and periodical titles. Otherwise the number of borrowing cases is much less affected than the number of lending cases by the above factors : the interlibrary loan can be more actively conducted in the group of libraries using facsimile or PC than the other group.

In this study, we reviewed and analyzed the influencing factors of technology transfer performance in the previous studies (52 domestic journals and theses) and classified the various influencing factors into 6 top factors and 13 sub-factors based on the theoretical background. The study results of previous articles were analyzed by meta-analysis method so as to calculate the overall average effect size of influencing factors of technology transfer performance. As the result, the overall effect size (ESr) calculated through meta-analysis applying random effect model is .269, which corresponds to the medium effect size. By comparing effect sizes of influencing factors, the four(4) key influencing factors were also identified, which are 'number of researchers', 'dedicated organization', 'possess technology', and 'external cooperation'. The technology transfer performance are divided into three types: the number of technology transfers, technology transfer income, and other technology transfer performances. The major influencing factors of each type are derived through meta-analysis at the sub-category level. As moderator variables, the paper type and the data type were analyzed but no significant results were obtained. Since this research is limited to the technology transfer, it is necessary to carry out the study related to the influencing factors on the technology commercialization as following study.

The study aims to extract the framework of sub-factors of spatial sense, to develop test instruments based on the framework to investigate the actual spatial sense ability of fourth to sixth graders in elementary school and to analyze the results. According to the framework of sub-factors of spatial sense of the study, spatial sense has two factors of spatial visualization and spatial orientation. Spatial visualization is divided into mental rotation, mental transformation and figure-ground perception while spatial orientation is categorized into direction sense, distance sense, and location sense. Based on the framework, the test instrument for spatial sense ability was developed and the test was conducted to 430 fourth to sixth students in five elementary schools in capital areas. The following conclusions were drawn from the results obtained in the study. Firstly, the higher school year gets, the more spatial sense grows. However, spatial visualization is developed much more than spatial orientation and their order is reversed with higher graders. Secondly, the most insufficient abilities among fourth to sixth elementary school students' spatial sense were mental transformation of spatial visualization and location sense of spatial orientation. Thirdly, the reasons of differences in sub-factors of spatial sense and graders seem to be from effects of students' learning experiences of spatial sense of mathematics curriculum and the complexities of test items.
