국립과천과학관은 상설전시관 외에 천체관측소, 천체투영관, 스페이스월드 등의 천문우주시설을 갖추고 있으며 이들 시설을 활용한 천문대중화 프로그램을 지속적으로 운영하고 있다. 그러나 학령인구 감소와 관람객의 요구수준 증대 및 계층의 다변화에 따라 더 이상 과학관 간의 경쟁이 아닌 문화센터, 놀이공원, 박물관 등 여러 유형의 놀이, 문화 시설과 경쟁해야 하는 현실에 직면하고 있다. 이로 인해 과학관을 방문하는 관람객수는 정체하거나 점차 줄어드는 추세를 보이고 있다. 따라서 일정한 수준의 관람객을 지속적으로 확보하기 위해서는 새로운 수요를 창출하는 것 못지않게 과학관 관람객층을 다변화하고 이들의 재방문율을 높이는 것이 중요하다. 2016년 1월부터 2017년 7월까지 국립과천과학관 천문우주시설의 비 상설 프로그램인 "공개관측회"와 "저자특강"에 참석한 관람객을 대상으로 재방문율 조사를 하였고 이를 이용해 관람객의 프로그램 참석 빈도, 특성, 고객충성도 등을 분석하였다. 충분한 표본 확보와 자료의 객관적인 분석을 위해 소수의 적극적인 관람객만 참여하는 설문조사 방식을 사용하지 않고 온라인에 등록된 모든 참석자의 목록을 추출하여 사용하였다. 조사기간 프로그램에 참여한 총 인원은 6,700명이었으며 2회 이상 방문을 한 관람객의 재방문율은 38.8%를 나타냈다. 총 4,755명이 참석했던 "공개관측회" 만을 대상으로 한 재방문율은 29.8%, 총 1,925명이 참석했던 "저자특강"만을 대상으로 한 재방문율 41.7%의 결과를 얻었다. 또한 두 프로그램을 모두 참석한 관람객은 전체 19.6%의 결과를 보였고 재방문자만을 대상으로 한 교차 프로그램 참석자의 비율은 50.4%를 나타냈다.

Application service provider(ASP) model is emerging as a new form of application outsourcing. ASP model may be attractive for small companies and even some medium-sized companies because these companies lack appropriate resources and technical expertise to develop and operate their information system. However, studies of ASP model have so far been neglected. Service quality is argued to be a crucial success factor for ASP, but yet there is not an empirically validated instrument for measuring ASP service quality. Therefore, this paper aims to develop and test a model for measuring ASP service quality. In order to accomplish these, SERVQUAL that has developed in marketing area were adapted to the context of this study. The research sample was designed by randomly selecting 300 different companies from the database that listed up the small companies participating in "ASP based e-business project for small enterprises". 240 usable responses were received by interview. The results are that reliability and tangibility impact user performances and satisfaction more than any of the service quality dimensions.

Recently, brisk up the construction of the spatial information, many people highly concern to tile information circulation of GIS. Each system like GIS has a structure of the information circulation to itself. In this paper, we study on the performance evaluation method of tile structure which to circulate tile spatial information based on the internet. To do this, we hypothesize values of content and scale of the geo-spatial information on each internet network and volumes of the information to circulate between internet networks. Then we suggest a method to evaluate the performance of the structure to aid the circulation of spatial information based on queueing model. Henceforth, with the volumes of data stored and circulated information of each GIS, this method can help to design the structure to circulate the GIS information more efficiently.

All roundabouts are designed based on "Roundabout Design Guideline, Ministry of Land and Transportation, 2014" in Korea. The guideline also provides the traffic volume criteria to convert from signalized intersections to roundabouts. While the criteria are based on capacity of roundabouts, left-turn ratio and the number of lane on approaches are not considered to calculate the capacity of roundabouts. Therefore it is difficult to apply the traffic volume criteria in the real world. In this study, we studied the impact of left-turn ratio and the number of lane on approaches into capacity of roundabouts using micro-simulation. It was found that the capacity of roundabouts is changed according to left-turn ratio and the number of lane on approaches.

Educators have recognized the usefulness of the e-BBS(electronic-Bulletin Board System) as an asynchronous communication medium for collaborative learning. However, theoretical outcomes to understand the structural analysis of thc e-BBS are not adequate enough. As a consequence, we are left with inadequate supportive tools to understand complex communication phenomena and to assist teachers to guide students to educational purposes. This can cause teachers to have a laissez-faire approach using BBS as a communication medium for education due to the lack of understanding the structural and overall situation. To address this issue, this paper presents a theoretical foundation to help understand the structure of discussion activities via the e-BBS and then presents a computational model, based on the structural analysis, for the behavioral analysis of participants. The formal representation of bi-directional discussion activities is realized by devising two graphs - the reply graph and the connection graph. Various measurements and statistics for the analysis are presented in the paper. To clarify the analysis, we classify the results produced through the analysis of discussion activities and participants' behaviors.

The purpose of the study is to investigate the status of assistive technology delivery system and to analyze issues on legislating assistive technology act in Korea. Many laws in different departments include regulations of providing assistive technology devices, and their range and types in various delivery entities tend to expand. However, a nationwide assistive technology delivery system for all individuals with disabilities that considers balanced expenditure among departments is not established yet. Two laws proposed to solve the situation were introduced and discussed as the following. First of all, the terminology of assistive technology and various products supported by different laws and departments should be aggregated and connected. Secondly, a nationwide assistive technology delivery system for all individuals with disabilities are to be established, regardless of departments or laws for certain purposes. Thirdly, a quality control system of all assistive technology products including user monitoring system should be regulated.

This study presents the strategic directions for Korean multi-brand fashion stores by running in-depth industry research and market analysis. Over 20 professionals were selected from Korean multi-brand fashion stores for this study and in-depth interviews were conducted to evaluate related subjects. The results of the study were as follows. First, Korean multi-brand fashion stores could be classified into three criteria: operating ownership, merchandise mix, and store identity. Second, operating ownership criterion was chosen for further investigations of strategies and directions of the multi-brand fashion stores. The operating ownership criterion consists of three types; department store types, specialty store types, and boutique types. Each type deploys different buying practice, organizational strategies, and distribution channels. Lastly, the suggested strategic directions for each type are summarized as follows. The 'department store type' should utilize its strong direct buying capabilities and acquisition of merchandising can be more effectively managed. The store should utilize its strong buying power as a tool to develop new private brands (PBs). For 'specialty store type', two key factors have been derived: market share expansion and positioning themselves to become a new distribution channel. To respond to these factors, the store needs to be perceived as a brand then diversify its business. Strengthening its brand will allow it to expand into a new distribution channel and also enable a strategic partnership with its competitor brands. The factors influencing 'boutique type' is personalization and uniqueness. With an emphasis on the uniqueness of products and merchandising it will be able to implement the role as a personal shopper and stylist to provide a very personalized service to its customers.
