이돈희 ( Don Hee Lee ),최강화 ( Kang Hwa Choi ) 한국품질경영학회 2010 품질경영학회지 Vol.38 No.4

This paper presents a research model, which identifies a relationship between medical error reduction, efficiency of organizational systems, and employee satisfaction with organizational support. The proposed model was tested through hypotheses, based on data collected from 210 respondents from the medical staff of large-sized (i.e., more than 500 beds) residential hospitals in cities of South Korea. The results of the study showed that medical error reduction is associated with corrective system and employee satisfaction with organizational support. Therefore, it is very important that organizations improve their employees` satisfaction by providing sufficient support (e.g., information support and sharing, work guide book, etc.) for their work. In addition, in organizational systems, the corrective system has positive relationship with medical error reduction. In terms of corrective procedures, leaders or managers can make improvements by providing and supporting a friendly work environment where errors may be reported without blame and discussed in order to be corrected.

This study examined the effects of internal and external factors on actual use, experience satisfaction, and continuous use intention of healthcare wearable devices/apps between general public and healthcare workers. The proposed research model with its associated nine hypotheses was tested using structural equation modeling. The findings of the study indicated that internal(knowledge and belief) and external factors (social influence, price value, performance expectancy, and effort expectancy) have positive effects on actual use, experience satisfaction, and continuous use intention of healthcare wearable devices/apps in both groups. However, for hypothesis 2, the standardized path coefficient between attitude and actual use was not significant in both groups. The results of the study provided operational strategies of healthcare wearable devices/apps to hospitals, companies, institutions, and policymakers to be developed new valuable items and effectively used them for well-being.

SI 개발 프로젝트 생산성 향상을 위한 프로젝트 관리 방법론 구축에 관한 연구

이돈희(Lee, Don-hee),김종은(Kim, Jong-eun) 한국IT서비스학회 2009 한국IT서비스학회 학술대회 논문집 Vol.2009 No.1

정보화가 기업 경쟁력의 핵심 요소로 부각되고 있으며 기업 및 정부기관은 앞 다투어 정보화에 투자하고 있는 상황이다. 정보시스템 개발 프로젝트도 이제는 대형 프로젝트 수가 급증하고 있다. 최근 소프트웨어 CMMi 수준에 관한 인증 여부는 기업 경쟁력의 핵심적인 요인으로 그 중요성이 날로 강조되고 있다. 또한 PMI의 PMBOK는 프로젝트 관리의 바이블 격으로 업종·업태를 불문하고 광범위하게 적용되고 있는 상황이다. 프로젝트 관리자의 관점에서 볼 경우 CMMi 모델과 PMBOK 모델간의 중첩되는 부분, CMMi 프로세스를 실적용 시 관리영역에 대한 혼선 부분, 또한 PMBOK 상위지침의 구체성 미흡 부분에 대한 통합 및 조정이 필요하게 되었다. 현재 상용되는 개발방법론에는 관리적인 요소가 매우 미약하고, 국내에 아직까지 체계적으로 정립된 관리방법론이 없는 상황이다. 따라서, 본 논문에서는 프로젝트 관리자가 숙지해야 하는 프로젝트 관리영역, 프로젝트 관리단계, 제반 절차, 유관 정보시스템과의 연동(Interface)등을 정보화 개발 프로젝트 생명주기(Life Cycle)에 맞춰 재구성 및 통합하여 프로젝트 관리자(Project Manager)에게 일관된 관점(Single Point of View)을 제시하여 프로젝트 생산성을 제고 하고자 한다.

The purpose of this study is to empirically test the effects of employees` perceived organizational support (POS) on service quality, customer satisfaction, and customer loyalty in health care organizations. The proposed research model was tested using structural equation modeling based on data collected from 193 pairs of employee-customer respondents in private and public hospitals with more than 500 beds. The results indicate that hospitals can improve the efficiency of their operations through POS for customer satisfaction and customer loyalty. One of the key findings of this study is that POS in health care organizations influence the service quality. Also, employee satisfaction is "an important determinant of operational performance", it leads to higher service quality and that it directly effects customer satisfaction because high-contact service industries have close interactions activities in employees and customers.
