  • In this paper, we develope a composite control law for linear systems with norm-bounded time-varying parameter uncertainties, which consists of a basic linear robust control do-signed so as to generate a desired transient time-response for the worst-case parameter variation and a nonlinear modification term designed so as to reduce cautiousness of the linear robust control in an adaptive manner. The proposed controller is established such that the reduction of cautiousness of the linear robust control is well incorporated into the achievement of a good transient behavior.

  • The purpose of this study was to examine the influence of consumer's ethical consumption consciousness and lifestyle on sustainable fashion. The data was analyzed by reliability analysis, factor analysis, cluster analysis, one-way ANOVA, Duncan's multiple range test, and multiple regression. The major results of this study were as follows. First, three factors of sustainable fashion were identified: eco-friendliness, recycling, and safety. Second, three factors of ethical consumption consciousness were identified: social ethics, environmental ethics, and public ethics. Based on these factors, the subjects were categorized into three clusters (high, middle, and low ethical consumption consciousness group). Third, four factors of life style were identified: pursuit of brand, appearance, cautiousness, and information. Based on these four factors, the subjects were categorized into three clusters (brand/appearance, cautiousness/information, and unconcerned group). Fourth, three factors of ethical consumption consciousness significantly influenced eco-friendliness factor of sustainable fashion. Also, the recycling factor of sustainable fashion was influenced by social ethics, environmental ethics, pursuit of brand, and pursuit of information. The safety factor of sustainable fashion was influenced by environmental ethics, public ethics, and pursuit of information. The results of this study suggest that practical and various environmental education need to be provided to consumers, because high environmental ethical consciousness consumers evaluated sustainable fashion positively. Additionally, accurate information on eco-friendliness, recycling, and safety of clothing products would need to be provided by fashion businesses through various routes, because those with information-pursuing lifestyle were found to have deep interests in sustainable fashion.

  • The purpose of this study is to find out the orientations and characteristic in clothes buying of each age group of elderly women, based on the actual self-image and the ideal self-image of clothing. Grasping the diversity of their clothes' buying orientations will be helpful in making a better merchandise production planning for apparel, and in launching new brands into the market. The study will also provide useful data in developing sales strategies which enable to supply goods that meet consumers' needs and tastes in the quality market, and consequently will help to classify the market. Samples were 488 women of 55 and over, dwelling in Pusan Metropolitan City. The data was analysed by using MANOVA, ANOVA, and the Cronbach's $\alpha$ reliability was also applied. The conclusions based on the theoretical background and the result of questionnaire surveys were as follows: 1. The order of priority of buying orientations based on clothes's actual self-image was 'practicality', 'cautiousness' and 'economical effectiveness' without regard to age. The items that showed the significant differences in 50's were 'cautiousness', 'experimentation', 'fashion-consciousness' and ostentatiouness, and in 70's were 'economical effectiveness', 'experimentation', 'impulsiveness' and 'environmental friendliness', and none in 60's. 2. The order of priority based on clothes' ideal self-image was the same as that of actual one, and there was no significant difference between age groups.

  • Purpose: The purpose of this study was to develop a tool for measuring the intra-operative caring as perceived by regional anesthesia patients. Methods: A preliminary instrument with 54 questions, based on a literature review and semi-structured interviews with 11 regional anesthesia patients, was developed. A group of experts revised individual questions, and 34 questions were finally selected. This tool was tested with 137 regional anesthesia patients admitted to D university hospital in B city from August to October 2008. Results: The validity and reliability of the tool were tested using factor analysis. After item analysis, one question with a correlation coefficient under .30 was discarded After performing factor analysis on the final 33 questions, 7 factors were identified; holistic needs fulfillment, consideration, protective environment, cautiousness, concern, information, physical comfort. The total variance shown in the test was 73.5%. A Cronbach alpha of 0.96 showed the reliability of the instrument. Conclusion: Results of this study indicate that the tool is statistically reliable and valid to measure the intra-operative caring perceived by regional anesthesia patients. This tool can be utilized usefully in assessing the effects of nursing interventions for regional anesthesia patients.
