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.

This study aims to analyze the causal relationship among teaching, cognitive, social presence and the learning outcome. It also provides the base data on the development of cyber education and its management strategies. During the first semester of 2009, 802 students at W cyber university completed surveys about their learning experience in teaching presence, cognitive presence, social presence, and learning outcome. The results indicated that there was a meaningful effect of teaching presence and cognitive presence on satisfaction, and that of cognitive presence on academic achievement. Based on these results, this study suggests instructional design methods and management strategies to improve the quality of learning in cyber universities.

The purpose of this study is to develop frameworks for evaluating reading programs for children provided by a public library. Logic Model based on outcome evaluations was applied for the framework development. While the logic model is generally composed of six factors, the frameworks developed in this study has four factors including input, activity, output, and outcome. Additionally, this study suggests outcome indicators which were driven from library data. Even though the evaluation frameworks were developed from specific programs operated by a public library, those might be able to be used to evaluate other libraries' programs for children since the target programs are commonly provided by public libraries.

The purpose of this study is to measure the outcomes of a program provided by a public library using the evaluation framework based on Logic Model. A reading program for children which was operated by a public library in Seoul was selected. The outcome evaluation was started with the analysis of the reading program process including planning, operation, and evaluation. Based on the analysis, a logic model framework for outcome evaluation was developed. For evaluation, user, bibliography, and circulation data were collected from the library KOLAS system. Additionally, the participant information were extracted from the final report drafted after the program. The research results show that the number of circulation of program participants was increased after the program. In addition, the range of reading topic was expanded. These findings indicate that the reading program is an effective program for promoting children's reading habit and that outcome evaluation might be a valid tool to measure the effectiveness of public library programs.

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.
