The purpose of this study is to construct a model for measuring and assessing service quality in public libraries based on the theory of service quality in marketing area. Firstly the degree of importance of service factors is measured and ranked according to the value of each factor. This importance ranking indicates the order of service improvement. Secondly the correlation model between service factors and customer's satisfaction and behaviour is established and verified in statistical method. The result shows that the order of service quality factors which have influence on the customer's satisfaction and behaviour is the order of service quality factors required preferential improvement.

오늘날 우리사회는 컴퓨터기술과 통신기술의 발달로 인하여 정보사회로의 이행이 급속히 진전되고 있으며, 기업들은 치열한 경쟁에서 살아남기 위하여 정보기술을 이용한 경영혁신에 많은 노력을 기울이고 있다. 정보기술의 급속한 발달에 따라 정보시스템의 기능이 조직의 내부에서 점차적으로 조직외부의 고객과 공급자 그리고 경쟁자 등으로 그 초점이 이동되어가고 있는 실정이다. 기업조지간에 통신망기술로 연결하여 정보를 교환하는 조직간정보시스템(Interorganizational System : IOS) 은 산업의 구조를 변화시킬 뿐만 아니라 , 기업에 잠재적 경쟁우위를 제공하는데 중요한 역할을 수행한다. 조직간정보 시스템이 특수한 형태인 전자자료교환(Electronic Data Interchange : EDI) 시스템은 표준양식에 의한 기업간의 거래문서를 전자적으로 컴퓨터와 컴퓨터간 통신 네트워크에 의해 교환하는 것으로서, 기업간 정보거개의 혁신적인 개선과 업무절차의 간소화에 의한 생산성의 향상 및 업무의 효율성 증대 등 획기적인 성과를 가져온다. 본 연구의 목적은 EDI 시스템의 성공적 구현에 영향을 미치는 주요요인에 대한 중요도 순위를 설문을 통하여 조사하고자 하는 것이다. 우선 EDI 시스템의 개념을 살펴본후, EDI 시스템구현의 성공요인에 대한 선행연구들을 고찰하고, 선행연구에서 도출된 주요요인들을 연구자별로 분류하여, 본 연구에서 조사하고자 하는 요인들을 설정한다. 다음으로 EDI를 이용하고 있는 국내기업의 70여개 기업체를 대상으로 설문조사를 실시하여 자료를 수집하고 본 연구에서 조사하고자 하는 19가지 주요요인에 대한 중요도를 실증적으로 분석하고자 한다.

Korean adults' internet addiction diagnosis measure, K-scale developed by Korea National Information Society Agency (NIA), has composed of 4 categories including 20 items. This scale can diagnose user's internet addiction with individual's questionnaire items. Most of previous research works were tried to know reasons of internet addiction and to judge whether adolescents are addicted or not with their samples. In this research, it is the goal to find the key component to judge individual's internet addiction by using a decision tree in the data mining field and a principal component analysis in statistics. From the experimental results, we would discover that tolerance and preoccupation factor is the most important one to affect adult's internet addiction.

Recently, as the problem of the traditional on-site labor-intensive construction production method has been raised due to changes in construction work labor and site conditions, the OSC method is gradually spreading as an alternative to this. Even in apartment houses, the application of the PC method is expanding centered on the underground parking lot, but the high cost structure is a problem compared to the conventional formwork method. In this study, factors affecting the calculation of construction cost in the economic evaluation, which are the core of determining the construction method for apartment buildings, are derived through domestic and foreign literature review and expert advice, the importance was analyzed through an opinion survey targeting industry experts. The measures to reduce construction cost were mainly derived from the improvement of the design and manufacturing process. It is expected that the factors affecting the construction cost and improvement measures of the PC method derived from this study will serve as a direction for technology development to spread the application of the PC method for apartment houses in the future.

This research studied the effect of visual improvement of "72 Hour Project" that has regenerated small scale derelict spaces in Seoul through citizen participation. 29 projects built form 2016 to 2019 were analyzed. The research analyzed landscape image preference of before and after status of projects using 12 pairs of landscape adjectives. Basic statistical analysis, correlation analysis, factor analysis, cluster analysis, and ANOVA were performed based on the survey results. Since the satisfaction level of the projects compared with the before-condition was 3.63 higher than 3.00, it could be concluded that there was an meaningful effect of visual improvement after completion of the projects. As the result of the factor analysis, landscape adjective pairs were categorized into two factors: harmony and aesthetics. Through the cluster analysis, four clusters were formed and characteristics of each cluster were identified. As the result of rhe cluster analysis, the cluster with the high harmony level and the aesthetics level showed the highest overall satisfaction level. Comparing each cluster, it could be concluded that the factor of harmony was more important than the factor of aesthetics in evaluating the satisfaction level of projects. Analyzing qualitative aspects of project groups, spatially well-balanced design with generous vegetation areas was more effective in landscape improvement than artistic design with visually strong installations. Further researches based on behavior studies of actual users are required to compensate the limits of this research. This research can contribute to establish the improved direction of policies to regenerate various types of small scale derelict spaces.

This study aims to generate baseline data for vitalizing the sales of functional cosmetics through an Importance-Performance Analysis (IPA) of the selection attributes of functional cosmetics. From the analysis of consumers' selection criteria, the study will assist functional cosmetics companies in reflecting consumer demands and therefore securing competitiveness. For this, general consumers aged over 20 years were surveyed for 5 weeks from Feb 23 through Mar 30, 2015, and 447 empirical data (response rate 88.9%) were processed through SPSS WIN 21.0 program for analysis. To conduct gender difference analysis on the IPA of the selection attributes of functional cosmetics, 17 selection attributes were categorized into 4 factors: functionality, labeling, popularity, and product. Cronbach's alpha for all factors was 0.5, proving the internal consistency and reliability of the survey. The survey results showed that while the entire average came out significantly higher for females (5.89/7points) than for males (5.66/7points) (p<0.001), the selection attributes 'anti-wrinkling', 'whitening function', 'functionality', 'expiration date', 'full ingredient labeling system' and 'various promotional events' showed significant gender differences. IPA results pertaining to gender showed 'price', 'functionality', 'spreadability' and 'full ingredient labeling system' as 2nd quadrant attributes, whereas female consumers selected 'price', 'whitening function', 'anti-wrinkling', 'functionality' and 'full ingredient labeling system' as attributes. Results show that businesses in the field of cosmetics and related areas need to prioritize improving the following factors that received low satisfaction from all consumers: 'price', 'functionality', and 'total labeling.' In particular, the 'price' aspects are considered to require reasonable and affordable pricing.
