This research compares the use of accounting data versus market data in the prediction of bankruptcy. Comparison is made through neural networks so that prediction accuracy is model-independent. Results of this study indicate that both market and accounting data provide useful information on corporate bankruptcies. Interestingly, using market and accounting information together can achieve substantial gain in prediction accuracy.

Public institutions or libraries urgently prepare comprehensive measures to improve web accessibility of their websites as booting web dependability and web utilization of disabled people. The purpose of this study is to propose the design guidelines for improving web accessibility of disabled people. The study, first, analyzed various web accessibility requirements based on web standards, web accessibility guidelines, and the related researches and proposed a web accessibility checklist with 42 requirement. Next, the study evaluated 15 websites of public institutions such as government departments, association of disabled people, and public libraries using the checklist. Finally, the study revealed non-adherence requirements and suggested website design guidelines in terms of contents configuration, sound, colour, keyboard handling, mouse handling, access, image processing, text processing, and code processing.

It is in the vortex of the Fourth Industrial Revolution in all areas of our society. Education is no exception. We all know that software is at the center of the education in the 4th industry revolution. It is very important for students to survey the ICT background in order to be good at software education. The OECD PISA has surveyed ICT background of students in a three-year cycle from 2003. This study analyzes PISA ICT statistical data based on the data released in April 2017. We compare and analyze the availability and usability items among the 81 items of the ICT background of the students. The results of linear regression analysis showed that Korea was the lowest among OECD countries. ICT availability is ranked 28 out of 30 countries and ICT usability is ranked 31 out of 31 countries. This reflects the fact that ICT education is not implemented in the country since 2008. For the students who will be the leaders of the future society, ICT education that had implemented in 2000 should be carried out quickly.

본 연구의 목적은 지방 환자의 거주지 입원과 서울 입원의 퇴원시 사망률을 비교하여 치료결과를 파악함으로써 향후의 효과성 분석을 위한 기초 자료를 제시하는데 있다. 2005년, 2008년도 환자조사 자료 중 지방거주 환자 자료 333,280건과 419,873건을 연구대상으로 하였으며, 자료분석은 기술통계, 카이제곱 검정, 로지스틱 회귀분석을 실시하였다. 퇴원시 사망에 영향을 미치는 요인에 대해 연도, 성, 보험유형, 의료기관유형, 입원경로, 내원경위, 주진단, 거주지의 효과를 통제한 후 살펴본 결과 거주지 입원환자의 퇴원시 사망률이 서울 입원환자에 비해 2.2배 높은 것으로 나타났다. 암환자의 경우도 효과를 통제한 후 퇴원시 사망률을 살펴본 결과 거주지 입원환자의 사망률이 서울 입원환자에 비해 3.4 배 높게 나타났다. 정부는 지역주민의 의료의 접근성을 높이기 위해 의료공급량의 확충과 분배보다는 지역의료의 질적수준을 향상시키는 방향으로 정책을 펼쳐야 한다.

The purpose of this study is to suggest positioning strategy according to franchising family restaurant brands. Discriminant Analysis was utilized to suggest methodological framework that seeks to find their relative positions in the family restaurant brands. As a result, the results show that five factors (employee service, physical environment, marketing, accessibility, and food quality) were extracted from Exploratory Factor Analysis that contains twenty three questions related to service quality of family restaurant. Second, Discriminant Analysis revealed that three factors out of five including employee service, physical environment, and accessibility showed the highest discriminant power. Based on the three factors, positioning maps were made and the location of four brands were identified. Third, service quality, satisfaction, and willingness had a significant influence on revisit intention.

Public library accessibility directly affects library usage, and the disproportionate distribution of accessibility is a decisive factor limiting the equitable provision of library services. In this regard, this study analyzed the spatial accessibility of public libraries in Busan and identified the factors affecting accessibility of public libraries using spatial regression analysis. As a results of the analysis, the accessibility of public libraries in the Busan showed large deviations by region. Also, spatial distribution of public libraries had no correlation with the settled population and use of public transportation, and location of public libraries was inefficient, in terms of social equity. The results of this study will assist to understand the spatial accessibility of public libraries in Busan, to identify factors that affect the accessibility. Moreover, this study is expected to be utilized as fundamental data for releasing disparities of the spatial accessibility and selecting new location of public library in Busan.

본 연구의 목적은 환자가 거주지가 아닌 타 지역에서 입원의료를 이용하는 요인을 규명하여 주민들의 의료이용에 대한 지역적 접근성을 향상시킬 수 있는 방안을 제시하는데 있다. 2005년 환자조사 입원자료 523,782건을 연구대상으로 하였으며, 2004년 의료기관평가 자료, 2005년 인구센서스, 2006년 보건의료자원실태조사를 이용하였다. 자료분석은 기술통계, 카이제곱 검정, 로지스틱 회귀분석을 실시하였다. 타 지역 입원의료 이용의 가장 큰 요인은 의료기관 소재지의 의료서비스 수준으로, 인구 10만명당 의료기관평가 점수가 9.5점 이상인 지역이 9.5점 미만인 지역에 비해 타지역 입원의료 이용확률이 8.3배가 높았다. 반면 인구 10만명당 병상수가 910병상 이상인 지역이 910병상 미만인 지역에 비해 타 지역 입원의료 이용확률이 2.0배 높았다. 정부는 지역주민의 의료의 접근성을 높이기 위해 의료공급량의 확충과 분배보다는 지역의료의 질적 수준을 향상시키는 방향으로 정책을 펼쳐야 한다.

This paper starts from one question: what are the key factors of the web accessibility policy, which is significant for realizing equity in the web and enhancing human dignity in the information society. To find significant factors for complying with web accessibility, this paper analyzes panel data of 16 Korean local governments (for five years: 2004-2009) according to the research design which is based on the demand and supply balance model and consists of four variables : 'legal and institutional environment (including legal infrastructure)', 'financial foundation (fiscal self-reliance ratio)', 'policy inputs (amount of imformatization budget, employee of information experts)'and 'policy demand (internet usage rate, the number of disabled people and elderly people)'. From the results of this study, this paper can explain the mechanism and impact factors on the web accessibility policy of Korean local governments. Some factors are critical to improve web accessibility: (1) the importance of policy demand, (2) the importance of policy inputs, (3) the importance of legal and institutional environment. Finally, this paper concludes with some suggestions to enhance the web accessibility capacity for Korean local governments: (1) improve awareness on web accessibility, (2) develop a standard and invest R&D on web accessibility, (3) foster experts in web accessibility.

Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.
