One of the most visible developments in Decision Support Systems (DSS) was the emergence of rule-based expert systems. Hence, despite their success in many sectors, developers of Medical Rule-Based Systems have met several critical problems. Firstly, the rules are related to a clearly stated subject. Secondly, a rule-based system can only learn by updating of its rule-base, since it requires explicit knowledge of the used domain. Solutions to these problems have been sought through improved techniques and tools, improved development paradigms, knowledge modeling languages and ontology, as well as advanced reasoning techniques such as case-based reasoning (CBR) which is well suited to provide decision support in the healthcare setting. However, using CBR reveals some drawbacks, mainly in its interrelated tasks: the retrieval and the adaptation. For the retrieval task, a major drawback raises when several similar cases are found and consequently several solutions. Hence, a choice for the best solution must be done. To overcome these limitations, numerous useful works related to the retrieval task were conducted with simple and convenient procedures or by combining CBR with other techniques. Through this paper, we provide a combining approach using the multi-criteria analysis (MCA) to help, the traditional retrieval task of CBR, in choosing the best solution. Afterwards, we integrate this approach in a decision model to support medical decision. We present, also, some preliminary results and suggestions to extend our approach.

The purpose of this research was to understand the structure of the experiences of turnover among hospital nurses. The research question was 'What is the structure of the experiences of turnover among hospital nurses?' The sample consisted of 16 hospital nurses who experienced one or more turnover. The unstructured interview were carried out from July 15. through August 31., 1997. Intervewed by audio-recording and analyzed by Van Kaam's method. There were 361 descriptive expressions and priority classifications. The result summerized as 107 common elements, 38 syntheses of hypothetical definitions and 6 identifications of the structural definition. The structural definitions and hypothetical definitiones were as follows ; 1. There were different views on the turnover intention. Hard task, dissatisfaction of initial expectancy, uncomfortable relationship with doctors, inappriate reward, uncomfortable relationship with workers of other parts, uncomfortable relationship with patients, unreasonable promotion, uncomfortable relationship with co-worker, helplessness, poor environment of working conditions. 2. Motivating factor of turnover can be varied : self development, problem of social support, boring task, problem of relation-ship with the senior, unfair promotion, night duty. 3. Social supportive factors were co-worker support, senior support, self control, family support, time support. 4. There were different views on the job satisfaction. Task, relationship with patient, recognition, professionalism, promotion, working environment, relationship with co-worker, reward.

The purpose of this study is to confirm whether the task and system development process makes a significant influence on the system performance. The task is defined as a interdependency and system development process is defined as analysis, user participation and executive support. Field research was employed to empirically investigate the relationship among the variables. The finding of the study can be summarized as follows. The strict analysis under the task of high interdependency has a significant effect on the system performance. And high executive support is needed for the system performance under any level of interdependency.

Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems as TAM insists. Adaptive Structuration. Theory (AST) joins with TAM in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We found that collected data from 303 individual IT staffs in a national bank. Our results demonstrate that traditional theories on TAM (Technology Acceptance Model) need to be refined, when considering the TTF(task-technology fit). TTF render high influences on PU(perceived usefulness). PEU(perceived ease of use) and FOA(faithfulness on appropriation). And FOA influences highly on our dependent variable. Implications and directions for future research are discussed.

Previous studies have reported that decreased cognitive ability has been consistently associated with significant declines in performance of one or both tasks under a dual-task walking condition. This study examined the relationship between specific cognitive abilities and the dual-task costs (DTCs) of spatio-temporal gait parameters in stroke patients. The spatio-temporal gait parameters were measured among 30 stroke patients while walking with and without a cognitive task (Stroop Word-Color Task) at the study participant's preferred walking speed. Cognitive abilities were measured using Computerized Neuropsychological Testing. Pearson's correlation coefficients (r) were calculated to quantify the associations between the neuropsychological measures and the DTCs in the spatio-temporal gait parameters. Moderate to strong correlations were found between the Auditory Continuous Performance test (ACPT) and the DTCs of the Single Support Time of Non-paretic (r=.37), the Trail Making A (TMA) test and the DTCs of Velocity (r=.71), TMA test and the DTCs of the Step Length of Paretic (r=.37), TMA test and the DTCs of the Step Length Non-paretic (r=.36), the Trail Making B (TMB) test and the DTCs of Velocity (r=.70), the Stroop Word-Color test and the DTCs of Velocity (r=-.40), Visual-span Backward (V-span B) test and the DTCs of Velocity (r=-.41), V-span B test and the DTCs of the Double Support Time of Non-paretic (r=.38), Digit-span Forward test and the DTCs of the Step Time of Non-paretic (r=-.39), and Digit-span Backward test and the DTCs of the Single Support Time of Paretic (r=.36). Especially TMA test and TMB test were found to be more strongly correlated to the DTCs of gait velocity than the other correlations. Understanding these cognitive features will provide guidance for identifying dual- task walking ability.

A portion of several previous studies has been that when a product is to be presented as a gift it entaials a greater expenditure of time and money than when the same product is to be used by the buyer. While this might suggest that gift-giving is an especially involving purchasing sitution, the research to date has not been consistent in its evidence to support this view. One reason for this inconsistency in findings may be suggested that different gift-giving situations show considerably different levels of givers' task involvement. The present study designs to gain some descreptive understanding of the clothing gift-giving, and to test the relationship between varibles related to clothing gift-giving and task involvement of clothing gift-giving through different gift-giving senarios. Data (N=463) were collected via a questionnaire from housewives living in Pusan, and were analyzed by factor analysis, t-test, and cannonical analysis. Results support that differences in task involvement of clothing gift -giving cause different consumer behaviors in relation to clothing gift-giving.

This study tried to examine the relationship between superior leadership and emotional support from co-workers on task performance through performance evaluation fairness and self-efficacy in order to find factors that affect the task performance of a company in an uncertain market environment. For this purpose, 500 copies of questionnaire data were collected from corporate employees, and the research hypothesis was verified using Smart PLS 3.0. As a result of the study, superior leadership and emotional support from co-workers showed a positive (+) effect individually on the fairness of employee performance evaluation, Performance evaluation fairness showed a positive (+) effect on self-efficacy. Through this study, it was found that the fairness and self-efficacy of the performance evaluation accepted by employees affects work performance, providing a theoretical foundation for subsequent researchers. Practical implications are suggested to inspire employees to take on a challenge by managing them properly. In future research, based on the results of this study, various studies are needed on the factors that an organization must have for task performance.

Objective: This study investigated how social support and self-efficacy affect the quality of life of elderly people with chronic diseases. Design: The study consisted of descriptive survey research. Methods: A questionnaire covering social support, self-efficacy, and quality of life was distributed to 320 elderly people with chronic diseases. Pearson's correlation analysis was performed to examine the correlation between the respondents' social support (family support, friend support, medical support), self-efficacy (confidence, self-regulation efficacy, preference for task difficulty), and quality of life. Multiple regression analysis was also performed to identify the factors affecting the respondents'quality of life. Results: "Friend support" and "quality of life" (r=-636, p<0.001), had a negative correlation, "confidence" and "quality of life" (r=0.827, p<0.001), "self-regulating efficacy" and "quality of life" (r=0.736, p<0.001), and "preference for task difficulty" and "quality of life" (r=0.295, p<0.001)-had positive correlations. Friend support (𝛽=-0.164, p<0.001), confidence (𝛽=0.592, p<0.001), and self-regulation efficacy (𝛽=0.160, p<0.001) were found to affect quality of life. The independent variables showed the following degrees of influence, in order: confidence, friend support, and self-regulation efficacy. Their explanatory power was 73.3% (F=146.844, p<0.001). Conclusions: The quality of life of elderly people with chronic diseases can be improved by formulating health-promotion programs that foster a sense of community.
