기업내부에 존재하는 비즈니스 룰은 정형화되고 집중화된 하나의 시스템으로 구축되어 있는 것이 아니라 여러 서브시스템이나 실무자의 경험속에 산재되어 존재한다. 산재되어 존재하는 비즈니스 룰을 정형화된 형태로 집중관리가 가능하도록 구축한 도구가 BRE(Business Rule Engine)이다. BRE는 비즈니스 룰 관리를 빠르고 용이하게 하여, 기업의 경쟁력 향상에 매우 효과적인 기여를 한다. 하지만 BRE도입시 고려해야 할 품질특성을 판단할 뚜렷한 기준을 가지고 있지 못 하기 때문에 고가의 솔루션인 BRE도입에 많은 어려움을 겪고 있다. 본 연구에서는 국제 표준 ISO/IEC 9126를 기반으로 BRE가 갖추어야 할 품질특성을 정의하고 BRE 도입시 고려해야 할 품질특성을 판단할 수 있는 판별분석기법을 통해 BRE를 명확히 이해할 수 있는 품질평가모델을 제시함으로서 이러한 문제를 해결하고자 한다. 또한 본 연구의 결과는 실제 구축된 BRE 사례들에 대해 판별분석기법을 통해 검증하며, 검증된 품질평가모델의 활용방안을 제시한다.

소프트웨어 개발과정에서 사용자 요구사항을 정확히 만족하기 위해서는 사용자 관점에서 요구사항 검증을 위한 방법이 필요하다. 이것은 사용자의 요구사항이 시스템 개발자에게 적절히 반영되어 개발시스템이 보다 더 효과적으로 설계 및 구현이 가능하여 사용자가 요구하는 품질의 소프트웨어 시스템을 구현할 수 있기 때문이다. 본 논문에서는 시스템 구현 전 단계에서 사용자 요구사항을 효율적으로 검증할 수 있는 RV-UI 모델을 제안한다. RV-UI 모델 시스템은 상용화된 사용자 인터페이스를 프로세스별 기능 모델로 표준화하였고, 카노(Kano)의 이원적 품질이론을 적용한 인터페이스를 통해 명확한 사용자 요구사항의 검증과 체계적인 요구사항의 형상관리를 하도록 설계하였다.

This study aims to verify whether field-dependence and field-independence cognitive style have regulatory effect or not on information quality and system quality of digital textbooks in learning satisfaction. In order to accomplish the purpose, the research was carried out with 325 students of digital textbook research school who are fifth and sixth grade at a primary school living in Seoul metropolitan city. Results from the verification of hypotheses are as follows: when learning satisfaction of digital textbooks is affected by information quality and system quality influence satisfaction, it is given a positive moderating effect by the variables of field-dependence and field-independence cognitive style.

The purpose of this study is to develop and prove service quality measurement model and indicators which are able to measure objectively service quality of digital libraries in Korea. Literature review and Delphi survey are used to investigate service quality dimensions. User perceived service quality performance was measured to validate DL-SQI model with three digital libraries. Finally DL-SQI(Digital Library-Service Quality Index) model was developed which is composed of four primary dimensions. The survey results reveal that reliability coefficient is 0.8 which means high reliability of survey and it suggests that DL-SQI model based on the above dimensions is proved through confirmatory factor analysis.

This research was intended to investigate the influence of relationship quality by servicescape of Korean restaurants on loyalty targeting Busan city area. For this, a research model was designed and hypotheses were drawn through literature investigation. 300 copies of the questionnaire for a survey were distributed from 6th to 24th of May, 2013, and then 288 copies were adopted for the empirical analysis. As for data processing, the data were analyzed by using SPSS win version 18.0 statistics package program and were verified through frequency analysis, reliability analysis, factor analysis, and regression analysis. The result of this empirical study was summarized as follows. First, as a result of verifying the influence of servicescape factors on relationship quality, cleanliness, comfortableness, and accessibility among the servicescape factors had significant effects on commitment among the quality factors. Second, the result from verifying how the servicescape factors affected trust showed that attractiveness, comfortableness, and accessibility had significant effects on trust. Third, commitment and trust among the relationship quality factors were found to have significant effects on loyalty.

The purpose of this study is to explore latent variables that affect users' satisfaction of mobile internet and to estimate a composite relationships among parameters. In order to examine causative significance between dependent variables and each of the independent variables, we redefined the variables, the quality of information, system and service derived from the DeLone and McLean's model. And we found out the new independent variables: security and service charge. Prior research adopted mainly TAM(Technology Acceptance Model) to investigate the user acceptance of information services or system. Therefore, it is significant that we developed our research model to appropriate on mobile internet's inherent nature and that focused on the important variables like service charge and security. In empirical approach, we surveyed 435 samples and conducted structural equation modeling and multi-regression analysis to estimate the regression parameters. The results of the study illustrated that our hypotheses covering the quality of information, system and service, security and service charge were supported.

This study is conducted to investigate the relationships among service quality, satisfaction, and revisit intention of franchise snack bars customers located in Busan. The quality of franchise Korean snack bars' service was estimated by examining three sub-dimensions: service environment factors, interaction factors, and outcome quality factors, which are classified from Brady & Cronin's third-dimensional model. The survey was performed from March 9th to March 13th in 2015. Total 300 questionnaires were distributed and 272 questionnaires were employed for final analysis. SPSS 21.0 program was used to derive the following: factor analysis, reliability analysis, correlation, simple regression and multiple regression analysis. In results, the approachableness such as convenience for access was the most important reason when people choose a franchise Korean snack bar company followed by food taste and reasonable price. In addition, the results indicate that service environment quality, interaction quality, and outcome quality have all positive impact on the customers' satisfaction as well as revisit intention. Specifically, outcome quality have the greatest influence on the satisfaction and revisit intention among three service quality factors. This outcome proves that Korean snack bar franchise companies need to investigate more to improve their outcome quality such as food quality and serving time to satisfy customers. In conclusion, current study confirmed the relationships among service quality, satisfaction, and revisit intention in context of franchise snack bar stores. These results will suggest the snack bar foodservice segmentation as valuable marketing strategic, and that it can be utilized as a fundamental data to establish an efficient business plan in the industry.

In general, user requirements in web-based learning systems are divided into functional and non-functional requirements. Developers are responsible for the verification of quality related requirements, which is known to be difficult to perform. This paper suggests a verification method that can be applied in the area where the conformance of implementation for non-functional requirements is required. The paper performs tests for non-functional requirements by using the information extracted from quality related features that have imposed constraints on design activities.
