Purpose: The purpose of this study was to investigate differences in smoking related characteristics and psychological features of coronary artery patients by the stages of change in smoking cessation behaviors. Method: Subjects for this survey were 97 patients who were smoking when doctors diagnosed them to have coronary artery diseases. Result: Subjects were distributed 21.6% in precontemplation stage, 24.7% in contemplation stage, 17.5% in preparation stage, 19.6% in action stage, and 16.5% in maintenance stage respectively. The numbers of previous attempts to quit smoking of subjects in precontemplation stage(mean=3.00, SD=3.71) and contemplation stage(mean=2.63, SD=2.32) were significantly lower than that of subjects in preparation stage(mean=5.82, SD=6.20). Benefit scores of subjects in maintenance stage were significantly greater than those of subjects in precontemplation stage. Self-efficacy, barriers, seriousness, and nicotine dependency were not significantly different by the stages of change. Number of signs and symptoms related to smoking which subjects were experiencing were not significant by the stages of change too. Conclusion: Future intervention programs for smoking cessation should be focused on the strategies to enhance the realization of health benefits that patients might acquire from smoking cessation.

Purpose: This study examined the validity and reliability of the Korean version of the Self-Care in Chronic Obstructive Pulmonary Disease Inventory (SC-COPDI) and the Chronic Obstructive Pulmonary Disease Self-Care Self-Efficacy Scale (SCES-COPD). The SC-COPDI consists of the Self-Care Maintenance Scale (SCMES), Self-Care Monitoring Scale (SCMOS), and Self-Care Management Scale (SCMAS). Methods: The original tool was translated using a back-translation process. Participants were 241 patients with COPD at the Chonnam National University Hospital in Korea. The construct validity was verified through confirmatory factor analysis, and reliability was verified using Cronbach's α. Results: The SCMES consisted of 10 items of three factors-one of four factors was deleted from the original tool. In the SCMOS, there were six items of two factors after two items were deleted from the original tool. The SCMAS consisted of the original 10 items of three factors. The SCES-COPD consisted of six items of two factors, with one item removed from the original tool. The model fit indices of all tools were good, and the construct validity was confirmed. Cronbach's α of SCMES was .72, SCMOS was .90, SCMAS was .81, and SCES-COPD was .85. Conclusion: The Korean version of SC-COPDI and SCES-COPD are valid and reliable instruments for measuring self-care in people with COPD. These instruments can be used in self-care studies of COPD patients in Korea.

The study aims to determine the significance and characteristics of self-similarity inherent in natural objects or phenomena, the existence of self-similarity in design created by fashion designers, and the traits and internal significance implied in self-similarity and their effects on fashion. The subject of the study is Viktor & Rolf, and the scope of the study is the collections created from 2001 to 2014, which include designs implemented in their early years and those unveiled in the media. Self-similarity means attributes of a fractal structure appearing without change in the original form, even after modification of scale or direction in terms of shape or phenomena. As self-similarity is applied to the arts and design sectors, it leads people to pay attention to fundamental characteristics and intrinsic forms as a factor of expressing a unique creative world. Analysis of Viktor & Rolf collections generated ribbons, overlapping/juxtaposition, side decorations and exaggerated design elements as basic units of self-similarity. These factors had self-similarity rates as high as 84%. Self-similarity was established as design elements formed in the incipient stage were repeated in a certain form, and continued for a long period of time. It served as an element that recognizes design and a fashion designer at the same time. Characteristics of self-similarity appearing in Viktor & Rolf collections can be summarized as homeostasis based on an equivalent relationship, balance based on self-organization, reducibility into essential elements, and uniqueness based on odd shapes. These characteristics influenced the pursuit of consistent brand image, the maintenance of a fashion designer's creative world, the formation of styles and the expression of a fashion designer's identity.

In recent years, numerous mega-sized and complex civil infrastructures are being constructed all over the world. Therefore, more precise construction and maintenance technologies are required for these complicated construction projects. Especially, exact strength measurement and curing process monitoring of the concrete structures are very crucial to confirm the safety and effectiveness of these complicated structures. In this paper, a new Quick Response (QR) code-based concrete strength labeling technique using embedded self-sensing monitoring system is introduced. It is important to note that the QR code-based concrete labeling technique enables easy access of the databases related to the concrete strength at anytime, anywhere, and any smart PC devices. Finally, by integrating the proposed QR code-based concrete labeling with the concrete strength databases already prepared at a designated web-server, a feasibility of the current system is investigated for a next generation concrete life-cycle quality maintenance.

Objectives: The purpose of this study was to identify the stages of change distributions for nine major health behaviors among poor children in underserved area, and to provide basic information for developing specific objectives and strategies for health education program. Methods: The health behavior data were obtained with a self-administered questionnaire and analysed for 3,081 poor children in 106 local children's centers nationwide. Stages of change classification were based on self-reported responses to five statements. The health behaviors included were balanced diet, safety behavior (helmet and protective device use while riding), regular exercise, smoking, alcohol use, drug use, sleep pattern, weight management and stress management. Results: Poor children were more likely in precontemplation and less frequently in action and maintenance stages for a safety behavior. 33.1% of respondents were precontemplators, 29.9% contemplators, and 6.5% in preparation stage. Only 4.3% and 9.6% were in action and maintenance stages, respectively. Gender differences were apparent. Boys were more likely to be precontemplators for nine health behaviors. Children from the lowest socioeconomic status and disrupted family were more likely to be in precontemplation for weight management and exercise behaviors. Children living with both parents were more likely to be in the action and maintenance stages for nine health behaviors. Stages of change for balanced diet and smoking were significantly related with those for other eight health behaviors. And the stage of exercise adoption was found to be significantly related with those for other seven health behaviors. Conclusion: Safety education must receive high priority in health education program for low income children. Balanced diet smoking cessation and regular exercise could be a possible gateway behavior toward healthier lifestyle practices.
