This study shows the process design and forming analysis of permalloy shielding can that support the automobile multi-display parts to indicate the accurate information of car. This study is particularly important, since the accuracy of permalloy shielding can is known to affect the magnetic properties such as coercivity and permeability quite sensitively. The objective functions are defects such as hemming wind, hemming length, hemming wrap and tightness in prehemming process. The pre-hemming angle is considered as design parameter. The commercial finite element program PAM-STAMP™ was used to simulate the pre-hemming and hemming process. The ANN (Artificial Neural Network) has been implemented for minimizing of objective function and for investigating effect of punch angle relevant to the pre-hemming process. The results of analysis to validate the proposed design method are presented.

Some groups do ethical activities (such as ethical slogan t-shirt campaigns) only to complete the requirements for ethical duty; consequently, some people question the effectiveness of those products. The attributes of ethical slogan t-shirts should be considered seriously to reduce skepticism when planning a campaign. Researchers can also suggest a new purpose for ethical t-shirts using an ethical message. In study 1, we conduct a conjoint analysis that suggests realistic multi-attribute choice decisions. The suggested multi-attributes wear design aesthetic (high/low), price (high/low), where we donate (close/far), and the size of firm (big/small). In addition, participations were divided into two groups according to eco-friendly attitudes to confirm differences in choices between two groups. Study 1 showed that price is the most important attribute, but design aesthetic also remains important. In addition, a group that has a high eco-friendly attitude thought "where we donate" was more important than other groups. In study 2, a pre-post approach investigated wearers' attitude changes. We also divided participants into two groups and one group wear high level design aesthetic t-shirts (and vice-versa) to measure the attitude change difference. As a result of study 2, the wearers partially changed their eco-friendly attitudes. The group that wore high design aesthetic t-shirts showed a greater difference than other groups. Through this study, we conclude that customers seriously considered the design aesthetic. Finally, wearing ethical slogan t-shirts can change the attitudes of wearers.

The purposes of this study were to segment male and female college students on the basis of sneakers' benefits and purchasing behaviors of each market segment. The research method was conducting a survey of 408 male and female college students in Seoul, Gyeonggi-do, Gwangju and Jeollanam-do province. The data were analyzed by Cronbach's α, factor analysis, cluster analysis, χ² test, ANOVA, and Duncan test. The results were as follows. First, they were segmented into 4 consumer types(positive benefits, economy/ personality, fashion/famous brand pursuit, and an unconcerned group) by the benefit of sneakers. Second, the evaluation criteria of the products were significantly different depending on each sub-group in terms of the type and quality of material, weight, colors, design, brand, elegance, fashion trend, and coordination. In the case of purchasing information, the sources of sneakers showed significant differences according to the sub-group in all factors except for the past shopping experience. All types of stores and styles were significantly different depending on the sub-group. Therefore, the results of this study supported that benefit segmentation in sneakers can be useful as an effective variable for evaluating market segmentation.

The purpose of this study was to examine the effects of laughter therapy on mood, state anxiety, and serum cortisol based on a Stress-Coping Model for preoperative breast cancer patients. Methods: The study used a nonequivalent control group pretest-posttest design. The participants were 40 breast cancer patients who were admitted to one general hospital for surgery in 2009 (experimental group 23, control group 17). The experimental group received one hour laughter therapy consisting of dance, lots of laughter techniques, and meditation. Results: The mean ages were 47 years (experimental group) and 49 years (control group). There were no significant differences in demographic and disease-related characteristics between the two groups. After the intervention, the scores of mood and state-anxiety of experimental group were significantly improved than those of control group. However, no difference was found in serum cortisol. Conclusion: The laughter therapy was partially effective in improving stress response in patients with breast cancer. Further research is needed to develop and evaluate the longer periods of interventions to testify the effects on serum cortisol, and other biochemical variables.

This study is to innovate policy service development by utilizing beneficiary - centered service design to public information and public data and services that citizens can experience. The Gov 3.0 Design Group operated by the Dongbuk Regional Bureau of Statistics in Daegu in 2015, proposed a 'start-up decision support service' for pre-founders, using data mining on the GIS spatial information held by the Statistical Office and real-time settlement information of credit card companies. For this, service design process and methodology were adopted and participation of various stakeholders. This study suggests that national design activity based on service design is effective in transforming public service based on government information disclosure. It is also worthwhile as an approach that can be considered when the government wants to release or open information or public data in useful form to the public.

Purpose: This study was conducted to investigate the effect of music therapy as auditory stimulus on the heart rate and behavioral state of premature infants. Method: The study design was a non-equivalent control group pretest-posttest design. Forty premature infants who were admitted at NICU were selected and assigned to two groups, experimental and control. Data were collected from April 20 to July 31, 2003 and analysed using Wilcoxon rank sum test and ANCOVA. Infants in experimental group were given music therapy for 20 minutes daily in 7 days at the average level of 56dB. Results: The first hypothesis that 'Infants in the experimental group will be lower in heart rate than those in the control group' was rejected(F= .05, ρ= .816). The 2nd hypothesis that 'Infants in the experimental group will be lower in behavioral state score than those in the control group, was supported(F=7.40, ρ= .010). Conclusion: The music therapy in this study was an effective nursing intervention in decreasing the heart rate and behavioral state score of premature infants.
