최근 기업의 회계정보시스템(AIS) 활용은 종전방식의 회계처리보다 효율적이고 합리적인 의사결정 지원이 가능하기 때문에 급속도로 확산되었다. 단순한 패키지 시스템부터 인사, 회계, 생산, 영업 등과 통합된 정보시스템까지 다양하게 도입되고 있다. 특히 대기업의 경우 통합시스템인 ERP시스템을 도입하고 있으며 ERP시스템의 도입과 함께 가장 두드러지게 중요성이 인식된 모듈이 회계정보시스템 모듈이다. 회계정보시스템의 특성은 한번 구축하면 추후 다른 정보시스템으로 변경하기 쉽지 않은 특징을 가지고 있다. 따라서 최초 도입 시 기업에 적합한 시스템을 도입해야 하며, 이때 성공적으로 도입할 수 있는 요인 찾아내야 한다. 그러나 기업이 회계정보시스템을 성공적으로 도입하기 위한 적정한 기준이 부족한 것이 현실이다. 본 연구는 이러한 문제점을 해소하기 위하여 사례 연구를 통한 회계정보시스템을 사용하고 있는 기업을 대상으로 선행 연구 결과를 기준으로 도입 시 중요하게 고려해야 하는 요인들을 분석하였다. 본 연구의 자료는 이미 AIS를 사용하고 있는 42개 기업의 설문 응답 자료를 토대로 분석되었으며, 평균 분석(Mean Analysis), 요인 분석(Factor Analysis) 등을 통하여 요인의 상관성을 분석하였다. 분석 결과로 기업이 AIS를 도입함에 있어 기업의 환경 조건보다 AIS를 도입 시 고려하여야 할 기준 또는 특성이 더욱 중요하다는 결론을 도출하였다. 따라서 본 연구의 성과는 기존 연구에서 도출된 AIS의 성공적 도입을 위한 요인에 대한 관계, 중요성 관계 등을 실증적 분석을 통해 규명하였다.

We develop the testing procedures about the homogeneity of the shape parameters of several inverse Gaussian distributions in our paper. We propose default Bayesian testing procedures for the shape parameters under the reference priors. The Bayes factor based on the proper priors gives the successful results for Bayesian hypothesis testing. For the case of the lack of information, the noninformative priors such as Jereys' prior or the reference prior can be used. Jereys' prior or the reference prior involves the undefined constants in the computation of the Bayes factors. Therefore under the reference priors, we develop the Bayesian testing procedures with the intrinsic Bayes factors and the fractional Bayes factor. Simulation study for the performance of the developed testing procedures is given, and an example for illustration is given.

Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.

This study is to classify the typology of e-business model based on the practical strategic model for successful e-business implementation. For that purpose, we review the conceptual framework of e-business and collected the data from 127 companies implementing e-business. The study is conducted in three phases as follows. First, six factors consisted of 22 items are derived through factor analysis. Second, Cluster analysis is employed to group the firms into different strategic patterns. A five-cluster solution is found to maximize the distances between cluster means across the six factor patterns. The models are named as 'ascendancy and convergence', 'expansion and moderate price', 'expansion and improvement of quality', 'ascendancy and process', and 'improvement of quality' respectively. Third, ANOVA is used to examine the impact on the performance differences attributable to the models. The results of the study are; (1) the 'ascendancy and process', 'expansion and improvement of quality' and 'expansion and moderate price' models were associated with significantly higher performance levels than the 'improvement of quality' model, and (2) the hybrid strategies are needed to implement e-business successfully based on the 'ascendancy and process' model.

The maintenance of educational facilities is divided into inspection and management of facility managers residing in the school and Educational Environment Improvement Projects(EEIP) to carry out maintenance work. Educational support organizations collect maintenance requests through facility inspections by school-specific facility managers, and carry out numerous maintenance projects during the year. The EEIP has the characteristic of Program Management with interrelationships between projects, not multiple projects management. The purpose of the EEIP is to eliminate the inconvenience of school facility users and increase their satisfaction, and achieving the goal is judged to be successful. Despite the importance of management and performance measurement utilizing Critical Success Factor(CSF) for the operation of successful educational facility maintenance management programs, the system for achieving the goals is insufficient. This study derives CSFs for each stage of the EEIP for the success of the EEIP. The CSFs for each stage of the EEIP is expected to serve as a basis for evaluation of educational facility maintenance management programs and can be used as an evaluation index in the future.

This study is to estimate the factor weights for a successful sea-ranching project using the Analytical Hierarchy Process. Furthermore, it investigates the policy implications revealed by the differences in group opinions throughout fishermen, government officials, researchers and the scholars when the weights are assessed. The hierarchy is constructed for the 3 levels of factors which must be evaluated for a successful sea-ranching project. The top level of factors is divided by the ecological factors and the socioeconomic factors. As the middle level of factors, there are 3 factors such as the choice of fish, the habitat environment and the production technology under the ecological factors and another 3 factors such as the stability of fishery society, economic factors, and the law & system under the socio-economic factors. And then, at the bottom level of the hierarchy, the economic factors have two different sub-factors such as the fishing revenue and cost. The law & system has also 3 sub-factors such as the accessibility to sea-ranching area, fishing method, and surveillance. The fishermen and government officials show us quite opposite tendencies in assessments of the weights while both the researchers and scholars reveal almost the same opinions positioned at somewhere between first two groups. The study also reports the evaluations of efficiency measures for resource recovery methods among the sea-ranching project, artificial reef, release of fish seeds, and marine protection area. Both the sea-ranching project and marine protection area have the same efficiency in terms of resource recovery while the artificial reef and release of fish seeds are revealed as somewhat less efficient methods comparing to the former two methods.
