서창교 한국정보시스템학회 1992 情報시스템硏究 Vol.1 No.-

A number of success story about various application areas including manufacturing, accounting, finance, education, and engineering are reported. MIS professionals predicted that expert systems would improve the productivity enormously. However, the expert system revolution has not happened yet. Although not reported in the open society widely, there are failure stories of expert systems. Most of problems concerning expert system failure stem from the non-technical issues such as cognitive and psychological problems rather than the technical issues. We hypothesize that human factor principle enables designers to handle most of these non-technical problems elegantly and to improve the performance and acceptance of the expert systems. Major reasons for expert system failure and needs of human factors are discussed. Human factor guidelines to expert system make the prospects of the expert systems with human factors clear and understandable.

국내 SCM 연구의 메타분석

서창교,김태우 한국산업경영학회 2013 한국산업경영학회 발표논문집 Vol.2013 No.-

메타분석은 일련의 연구결과들을 통합하는데에 있어 체계적이며 특정 주제에 관련된 여러 연구들의 결과를 정보자료로 사용하는 연구방법론이다. 본 연구는 공급사슬관리(SCM)분야의 2001년부터 2011년까지 10년간의 국내 SCM 연구논문 369편에 대한 메타분석을 실시하였다. 연구주제, 연구방법, 저자 등에 대한 빈도분석과 연구주제와 연구방법에 대한 교차분석, 해외연구와의 비교분석 등을 통해 국내 SCM 연구주제의 다양성과 향후 연구방향에 대해 제시하고자 한다.

전국 장애인복지관 웹 접근성 평가

서창교,황채영 한국장애인복지학회 2013 한국장애인복지학 Vol.- No.21

This research study tries to provide an overview of the web accessibility of the welfare centers for the disabled in Korea. From June 11 to June 22 one hundred and seventy websites were examined to find out how accessible they are with reference to the Internet Web Contents Accessibility Guidelines(KICS.OT-10.0003). Using the web accessibility tool, K-WAH 3.0, and Markup Validation Service from the World Wide Web Consortium (W3C), the study finds a disappointingly low level of website accessibility: 1) only 41.5% of websites provide on-line form label, 2) 85.3% of websites provide higher than 90% of compliance with repeative navigation link, 3) 32.0% of websites provide higher than 90% of compliance with on-line form labe and 4) more seriously, only 8.8% of websites pass the W3C markup validation. Therefore, many disabled Koreans may have substantial problems in accessing the centers for the disabled. 본 연구는 장애인 복지시설의 웹 접근성 준수 실태를 조사분석하기 위하여, 자동화된 웹 접근성 평가도구 K-WAH 3.0과 W3C의 마크업 유효성(Markup Validation) 검사를 이용하여, 한국장애인복지관협회의 170개 협회회원장애인 복지관의 웹 사이트에 대하여 웹 콘텐츠 접근성 지침의 준수실태를 분석하였다. K-WAH 3.0을 이용한 웹 접근성의 평가결과는 ‘온라인 서식 레이블 제공’이 준수율 41.5%로 가장 위반이 많았으며, ‘온라인 서식 레이블 제공’은 평가대상의 52개(30.6%) 기관만 90% 이상의 준수율을 보여, 장애인복지관의 웹 접근성 준수율은 매우 저조한 편이다. W3C의 마크업 유효성 검사에 있어서도 합격으로 판정을 받은 장애인복지관은 15개(8.8%)로 심각한 문제점을 가지고 있다. 웹 접근성의 개선을 위해서는 정보통신 접근성 인식제고를 위한 다양한 사업전개의 활성화가 시급히 필요하다.

토픽모델링과 소셜 네트워크 분석을 이용한 공급사슬관리 연구 탐색

서창교 한국SCM학회 2020 한국SCM학회지 Vol.20 No.1

We explored research dynamics in supply chain management(SCM) based on topic modeling and social network analysis. We used latent Dirichlet allocation for topic models and author co-citation analysis for social network analysis. We queried Web of Science database with ‘supply chain management’ and collected 10,538 research articles between 2002 and 2019. We used R program packages for topic modeling and CiteSpace for social network analysis. First, we explored how SCM research have developed in this period including publication trends, Web of Science categories, top 15 journals and research institutes. Second, we found 14 topics in supply chain management and identified three hot topics(Green SCM, Healthcare SCM, and Sustainable SCM) and three cold topics(Bullwhip Effect, Information Sharing, and Supply Chain Integration). Third, we examined the major researchers in SCM such as Sarkis J, Zhu QH, Gunasekaran A, and Seuring S and visualized the relationship among them with the author network. Fourth, we identified major keywords in SCM to represent the keyword network with the relationship among them. Performance is the most popular keyword. Inventory management and supplier-related words such as supplier development and supply evaluation stand next. Finally, conclusions and potential direction for further research were provided.

공급체인관리시스템 도입에 영향을 주는 요인

서창교,박종채,정은희 한국정보시스템학회 2003 情報시스템硏究 Vol.12 No.2

This study examined the factors that make Korean companies adopt supply chain management systems. By adding a group of inter-organizational factors, we extended an innovation-theory-based research model to study the information technology adoption. Sixty three questionnaires from 700 leading companies in Korea were collected and analyzed. Independent variables of the research included environmental, organizational, innovation, and relational characteristics. We found that supply chain management systems in Korean companies are at the initial stage of the adoption, in general. This research also found that company's environmental characteristics have insignificant relationship with the adoption of supply chain management systems. In addition, organizational characteristics (the support of top management, the size of organization, and the information technology infrastructure), innovation characteristics of the supply chain, and the power exercised over the supply chain played important roles in adopting supply chain management systems.

Patent Analysis in Assessing Supply Chain Management Innovation

서창교,황채영,김미애 한국인터넷전자상거래학회 2014 인터넷전자상거래연구 Vol.14 No.2

Patent documents record the nature of the invention and the direction of the technological development. Patent analysis refers to statistical techniques used to examine the information contained in a patent document. In this study, we assessed patents on supply chain management(SCM) to examine the research and development for SCM. The search time starts from January 1st, 1999 to December 31st, 2012. One hundred and twenty patents on SCM were collected from KIPRIS(Korea Intellectual Property Rights Information Service) database. The research analyzed patent counts, inventor analysis, assignees analysis, and International Patent Classification(IPC) analysis. The result of this study indicated that the number of patents is increasing continuously and most patents are invented by multiple inventors with corporation assignees.
