This paper proposes a new framework for variability analysis in QFD. The proposed framework considers the uncertainty of the information contained in the house of quality chart and analyzes the variability resulting in the outcome. A new framework provides a dominance index and a difference index for each pairwise ECs. The indices are helpful to evaluate priorities of each pairwise EC.

ㆍ These are not accidents ㆍ They are “unplanned incidents” that had multiple, obvious causes(both minor and egregious) ㆍ Prevention would have involved no more than good safety and good management practices ㆍ The outcome was predicable, and included loss of life, loss of prduction capacity, civil lawsuits, and OSHA citations.

본 연구는 공공도서관에서 어린이를 대상으로 진행하는 독서프로그램의 성과를 측정하기 위한 프레임워크 개발을 목적으로 한다. 프레임워크 개발을 위한 이론적 토대로 성과 평가에 기반 한 로직모델을 적용하였다. 로직모델의 요소로 제안된 6개 요소 중에서 가정과 외부적 요인을 제외한 투입, 활동, 산출, 성과 요인을 중심으로 프로그램 평가 프레임워크를 개발하였다. 연구결과로, 서울 시내 한 공공도서관에서 연구기간 동안 진행된 4개의 프로그램에 대한 평가 프레임워크와 성과측정을 위한 지표를 제안하였다. 프로그램별로 다양한 성과지표의 개발이 가능하지만 본 연구에서는 도서관 데이터를 기반으로 측정 가능한 지표를 중심으로 제안하였다. 본 연구 결과가 사례 연구로 진행되었지만 대상 프로그램이 공공도서관에서 일반적으로 진행하는 프로그램이라는 점에서 타 도서관의 어린이 대상 프로그램의 평가 프레임워크로 활용될 수 있을 것으로 기대된다.

본 연구는 공공도서관에서 운영하는 프로그램의 성과를 로직모델을 기반으로 개발된 평가 프레임워크를 적용하여 측정하고자 하였다. 성과 측정을 위해 서울 소재 한 공공도서관에서 운영하는 여러 프로그램 중 어린이 독서 프로그램을 선정하였다. 성과 측정 과정은 어린이 독서 프로그램의 계획, 진행, 평가 등의 업무과정 일체를 분석하여 로직 모델을 구현하였으며 이에 의거하여 예상되는 성과를 측정하였다. 데이터는 KOLAS를 통해 회원정보, 서지정보, 대출정보 등을 수집하였고, 프로그램 운영 현황에 대한 데이터는 프로그램 진행 후 작성된 보고서에서 추출하였다. 측정 결과 어린이 독서 프로그램에 참여한 회원들의 대출빈도가 상승하였고, 프로그램의 주제에 따라 대출 장서의 주제가 변화하는 것을 볼 수 있었다. 본 연구를 통해 독서 프로그램이 갖는 효과와 의미를 확인할 수 있었으며, 성과평가가 도서관에서 운영하는 타 프로그램 및 도서관 업무 등의 효과성을 측정하는데 유용한 도구가 될 수 있음을 보여주었다.

Objective : The aim of this study is to analyze on the external ventricular drainage [EVD] related ventriculitis, especially on their risk factors, management, and prevention. Methods : From January 2003 to December 2005, a total of 174 EVD catheters were placed in 112 patients at our institution. Of these patients, EVD-related ventriculitis were developed in 15 cases. Clinical variables such as age, sex, prior clinical diagnosis, placement of EVD insertion, duration of EVD, total numbers of EVD per person, and outcome were analyzed in theses cases to verify the risk factors, causative agents and outcomes. Results : Fifteen cases of EVD related ventriculitis were noted presenting infection incidence of 13.39 % per patient and 8.62% per procedure. Of these, five patients died from sepsis, seven patients were recovered from infection but neurological complications remained and three patients were recovered without any complications. Microbes were obtained from cerebrospinal fluid only in six patients. Acinetobactoer baumanii was the most common pathogen in our study [4 cases]. Among the various risk factors, only the prior clinical diagnosis showed the statistical significance. Patients who underwent decompressive craniectomy after severe brain trauma showed unfavorable outcome because of possible contaminative environment compared with other cases. Conclusion : EVD is considered as a safe procedure with good control of intracranial pressure if meticulous care is provided for EVD procedure and maintenance. With regards to risk factors and prevention, the higher incidence and unfavorable outcome was seen especially in patients with severe head trauma. Thus, special attention is required in these clinical settings.

Background In the management of mallet deformities, oblique retinacular ligament (ORL) reconstruction provides a mechanism for automatic distal interphalangeal (DIP) joint extension upon active proximal interphalangeal joint extension. The two variants of ORL reconstruction utilize either the lateral band or a free tendon graft. This study aims to compare these two surgical techniques and to assess any differences in functional outcome. As a secondary measure, the Mitek bone anchor and pull-in suture methods are compared. Methods A single-institutional retrospective review of ORL reconstruction was performed. The standard patient demographics, injury mechanism, type of ORL reconstruction, and pre/postoperative degree of extension lag were collected for the 27 cases identified. The cases were divided into lateral band (group A, n=15) and free tendon graft groups (group B, n=12). Group B was subdivided into the pull-in suture technique (B-I) and the Mitek bone anchor method (B-II). Results Overall, ORL reconstructions had improved the mean DIP extension lag by $10^{\circ}$ (P=0.027). Neither the reconstructive technique choice nor bone fixation method identified any statistically meaningful difference in functional outcome (P=0.51 and P=0.83, respectively). Soft-tissue injury was associated with $30.8^{\circ}$ of improvement in the extension lag. The most common complications were tendon adhesion and rupture. Conclusions The choice of the ORL reconstructive technique or the bone anchor method did not influence the primary functional outcome of extension lag in this study. Both lateral band and free tendon graft ORL reconstructions are valid treatment methods in the management of chronic mallet deformity.

In this study, the impact of organizational culture on the quality of social work services in hospitals were empirically analysed. A mailed questionnaire survey was conducted between February 19 and April 10, 2001. A sample of total 70 hospitals, including general hospitals with one social worker at least and single-department hospital with two social workers or more, were identified nationwide through the registry of Korean Association of Medical Social Workers and Korean Association of Hospitals. According to coping strategy and reacting pattern with the environmental changes, four types of organizational culture in each hospital, classified as group culture, developmental culture, hierarchial culture, and rational culture, were adopted for the independent variables. Three dimensional aspects of quality of social work service - structure, process, and outcome were selected as dependent variables in this study. Also the quality of social work service was distributed into provider-perceiving quality and consumer-perceiving quality The major findings were as following in summary; First, most social workers reported that the characteristic of culture in their hospitals are group culture the first, hierarchial culture the second, developmental culture the third, and rational culture finally in order of comparing the level of quality perceived between social worker's recognition. Second, service provider and consumer, The provider-perceiving quality showed less score than that of consumer, especially the lowest was the score of quality of outcome perceived by provider. Third, according to the types of organizational culture, there were significantly different levels of quality in total social work services, structure dimension and process dimension. The quality of outcome dimension did not show significant differences among the type of organizational culture. Finally, the most influential variables to the quality of social work service ice proved departmental form of social work unit, leader of social work unit, and developmental culture of hospital To assure quality services, accordingly, social work unit in hospital is required to be organized as a single unit, that means to be an independent department of which qualified social worker is supposed to control the unit. It is strongly recommended to develop leadership for the leaders of social work unit.
