A desirability function approach to a multiresponse problem is proposed considering process parameter fluctuation as well as distance-to-target of response and response variance. The variation of process parameters amplifies the variance of responses. It is called POE (propagation of error), which is defined as the standard deviation of the transmitted variability in the response as a function of process parameters. In order to obtain more robust process parameters, this variability should be considered in the optimization problem. The proposed method is illustrated using a rubber product case.

Researches for NN(nearest neighbor) query which is often used in LBS system, have been worked. However. Conventional NN query processing techniques are usually meaningless in moving object management system for LBS since their results may be invalidated as soon as the query and data objects move. To solve these problems, in this paper we propose a new nearest neighbor query processing technique, called CTNN, which is possible to meet continuous trajectory nearest neighbor query processing. The proposed technique consists of Approximate CTNN technique which has quick response time, and Exact CTNN technique which makes it possible to search accurately nearest neighbor objects. Experimental results using GSTD datasets shows that the Exact CTNN technique has high accuracy, but has a little low performance for response time. They also shows that the Approximate CTNN technique has low accuracy comparing with the Exact CTNN, but has high response time.

The purpose of this article is to depict the organizational effectiveness of "A" Subway Corporation based on the cognitive response of employees(subway drivers). To attain this purpose, several aspects of current personnel aid organization management system and organizational culture are surveyed through questionaire and analyzed by SPSS. The questionaire includes two parts of items. First, it includes items on personnel-related factors such as evaluation system job, wage, role, leadership and job satisfaction. Second, it includes items on organizational culture model suggested by Rousseau. The major findings are : 1) In general the cognitive response of driven concerning personnel-related aspects is to a certain degree negative. 2) The cognitive response of drivers concerning culture-related aspects is awfully negative. 3) Job satisfaction of drivers is highly related to role and leadership factors in terms of personnel-related aspects, on the one hard, and to achievement factor in terms of culture, on the other hand.

This study tried to examine the antecedents of antecedents of trust and customer response at the healthcare service. A total of 230 patient' data were used with a structural equation analysis. They were verified by covariance modeling, using SPSS 18.0 and AMOS 5.0program. Trust is significantly affected by the three factors. Doctors' professionalism and effort of relationship continuity have a positive impact on trust simultaneously. Also, brand reputation have a positive impact on trust simultaneously. But, Trust is not significantly affected by tangibles. And, Trust has a not positive impact on the word of mouth(WOM). Satisfaction has a positive impact on the repurchase and WOM. Repurchase has a positive impact on the WOM.

A reducing variation of quality characteristics is a typical example of quality improvement. In such a case, we treat the quality characteristic, as a response variable and need to find active factors affecting the response from many candidate factors since reducing the variation of the response will be achieved by reducing variation of the active factors. In this paper, we first derive a method of selecting an active factor by linear regression. It is well known that correlation between factors deteriorates the precision of estimators. We, therefore, examine robustness of the selecting method against the correlation in the data set and derive an evaluation method of the deterioration brought by the correlation. Furthermore, some examples of selecting and evaluation methods are shown to demonstrate practical usage of the methods.

This paper is aimed to analyze how to evaluate the choice of optimal management measures and level of control in fisheries management under the costly and imperfect management system by comparing with costless and perfect management system that is commonly assumed in the analysis of fisheries regulations. Fishermen would set the level of fishing efforts at the point where the marginal fishing profit for fishing effort is equal to the marginal level of fine under costly and imperfect management system. Therefore, under the case where the marginal fishing profit is higher than the marginal level of fine, the level of fishing efforts would be made at the point which is higher than the level of fishing efforts made under costless and perfect management system and is not a point where the economic profit is maximized in regulated fisheries. From this conclusion, the fishermens avoidance activities against regulations as well as the level of control in fisheries management substantially have an influence on the choice of fisheries management instruments. According to the analysis of optimal fisheries management policy, the economic profits in regulated fisheries are determined by the level of fisheries enforcement costs and total fishing profits, in which as enforcement costs increase the economic profits decrease. In addition, the economic profits vary in response to the level of control in avoidance activities. That is, as avoidance costs decrease, the economic profits increase. The determination of optimal level of control in fisheries management should be made at the point where the marginal regulation costs are equal to the marginal profits from regulated fisheries, in which marginal regulation costs are different according to the type of management measures. And the level of profits changes in response to different levels of avoidance activities. The management measure that can maximize the difference between the marginal regulation costs and marginal profits from regulated fisheries should be chosen as an optimal fisheries management instrument.

Due to the fact that nurses may deal with diverse populations in the work place, it is very important for then to maintain appropriate interpersonal relationships with clients. Nurses should maintain diverse types of relationships appropriately with patients with special needs and their families during crisis, other nursing colleagues and staff on the same team, clients in the school or work place as well as the community. In particular, a hospital is a society with a system and hierarchy, and the importance of interpersonal relationships is much more emphasized. In interpersonal relationships, it is very important for a person to communicate with others in an accurate manner, and when the communication is not achieved appropriately, the person may have troubles and experience distress and conflicts because of the inaccurate communication of thoughts. According to the findings of previous studies, nurses actually experience much distress in the work place because of the miscommunication that they have with others. The purpose of this study was to observe a correlation between Myers-Briggs Type Indicator and assertiveness behavior, and to exam the effects of assertiveness training on the assertiveness behavior and conflict management mode. The subjects of this study included 20 persons in the experimental group and 20 persons the in control group. Myers-Briggs Type Indicator was applied before the study. The assertiveness training group received six, 120 minutes sessions over a 3 week period. Pre-test on assertiveness behavior, Communication Conflict Inventory-General, Role Conflict Inventory- General, Conflict Management Mode was achieved for all the subjects prior to the training. Post-test was administered to all the subjects one week following the last session. The data were analyzed using SPSS PC program to obtain findings on mean. standard distribution, t-test, and Pearson correlation. The results are as follows: (1) Myers-Briggs Type Indicator Introvert/Extrovert was correlated to assertive behavior and avoid- response type conflict management mode. (2) The assertiveness training was correlated to assertiveness behavior, communication conflict degree, and avoid- response type conflict management mode. (3) The post-test scores between the training group and the control group were significantly different in assertiveness behavior and avoid-response type conflict management mode. It is suggested that more studies need to be done to differentiate the effects of Myers-Briggs Type Indicator and assertiveness training on assertiveness behavior and avoid-response type conflict management mode.
