This work reports the phase-change behavior and thermal stability of doped GeSbTe/GeSbTe bilayers. We prepared the bilayers using RF sputtering, and annealed them at annealing temperature ranging from $100^{\circ}C$ to $400^{\circ}C$. The sheet resistance of the bilayer decreased and saturated with increasing annealing temperature, and the saturated value was close to that of pure GeSbTe film. The surface of the bilayer roughened at $400^{\circ}C$, which corresponds to the surface roughening of doped GeSbTe film. Mixed phases of face-centered cubic and hexagonal close-packed crystalline structures were identified in the bilayers annealed at elevated temperature. These results indicate that the phase-change behavior of the bilayer depends on the concurrent phase-transitions of the two GeSbTe-based films. The dopants in the doped GeSbTe film were diffused out at annealing temperatures of $300^{\circ}C$ or higher, which implies that the thermal stability of the bilayer should be considered for its application in phase-change electronic devices.

In order to evaluate the behavior patterns of the ring beam by excavation at the vertical wall with circular section, the measured field datum were analyzed and evaluated in this study. Additionally, stress patterns of the ring beam with the change of excavation depth were estimated by using FE analysis. As the results, it was shown that the tendency of the measured values for the behavior patterns of the ring beam is similar to the analyzed values in FE analysis. From the tendency, it was confirmed that the behaviors of the ring beam due to change of excavation depth can predict by FE analysis using the suggested method in this study.

Purpose: This study examined the dietary behavior and the effects of nutrition education according to the stages of behavioral changes in sodium reduction of healthy male adults (20~69 years) in Gwangju Chonnam Regions. Methods: The research subjects were 200 male adults. Results: A significantly higher mean age was observed in the stage of Action Maintenance (A M) than in the stage of Precontemplation (PC) and stage of Contemplation Preparation (C P). Significant differences in the frequency of exercise, eating out, and preference for salty food, intake frequency of Udon, Ramen and Sundae according to the stages of behavior change in sodium reduction were observed. The dietary behavior scores and intake frequency-related dietary behavior scores of A M were significantly higher than PC and C P. Nutrition education for sodium reduction improved the dietary behavior score significantly in PC and C P, as well as the rate of correct answers of sodium-related nutrition knowledge in all stages. After the nutrition education, PC decreased greatly, and A M increased. Conclusion: Subjects in PC and C P had an undesirable propensity in dietary behavior, and nutrition knowledge compared to A M, but the nutrition education for sodium reduction greatly improved their dietary behavior and nutrition knowledge.

Since it was found out that the degree of medical contribution to health was timid. the direction of health policy studies has been focused on the personal health behavior. Participation in health has been closely related to the behavior. Those who have insisted on the new direction believe that the health policy laying stress on low cost and personal responsibility can avoid the pathology of medical policy and medical crisis. Participation in health has been very important method of changing health behaviors. It is certainly important to change bad health behaviors. But there is no deliberation of social structure here. Most health behaviors are the adaptation to social structure. The attempt to change the established adaptation behaviors without considering social structure is difficult to succeed. It is little meaningful to say the importance of the health behavior to those who have no choice but to be ill due to the poor environment and health risks. What can guarantee the real direction of community participation at least is the consciousness and behaviors of people's right.

The purpose of this study was to examine factors affecting compulsive buying behavior purchasing behavior. Four hundred female college students who have purchased fashion products via Internet shopping or TV home shopping were surveyed. For data analysis, descriptive statistics, factor analysis, t-test, and multiple regression analysis were used. As the results, 16.3% of respondents were revealed as compulsive buyers. For materialism instrument, four factors of materialism were found and labeled as 'material'. 'consumption', 'happiness', and 'economic value' factors. Also, two factors of entertainment pursuit were also identified as 'change' and 'adventure' pursuit. There were statistically significant differences between compulsive buyers and non-compulsive buyers in terms of materialism, success, and change pursuit, self-esteem, compensation, impulsive purchasing, and binge eating. Compulsive consumption scores were correlated to higher materialism, compensatory, impulsive purchasing, binge eating, shifting, entertainment pursuit, and lower self-esteem. Also, results of multiple regression revealed that compensatory, binge eating, and happiness pursuit were significantly to related to compulsive buying.

This study focuses on clothing as one of the most seasonal products and investigates consumer behavior related to climate change adaptation. This study addressed four objectives: (1) to identify the clothing behavior of consumers for the adaptation to climate change; (2) to identify the effects of fashion involvement and climate sensitivity on clothing attitude for the adaptation to climate change; (3) to identify the effect of clothing purchase time on climate sensitivity and clothing attitude for the adaptation to climate change; and (4) to identify the effect of consumer demographics on climate sensitivity and clothing attitude for the adaptation to climate change. A survey questionnaire was developed and implemented to collect data for measuring clothing involvement, fashion involvement, and climate sensitivity. In addition, clothing involvement, clothing assortment needs, and clothing worn for the adaptation to climate change were measured. A total of 349 responses were analyzed by t-test, ANOVA and path analysis with SPSS18.0. The results of the analysis are as follows. Changes in temperature were considered more important than changes in weather for the functional needs of clothing, purchase needs, and assortment items needs. The assortment items wearing for the adaptation to climate change varied depending on the temperature and weather. Fashion involvement directly influenced clothing assortment needs and indirectly influenced the clothing worn for the adaptation to climate change. In terms of clothing purchase time, those purchasing clothing before the season begins, tended to have a high fashion involvement and clothing attitude for the adaptation to climate change. Those in their twenties and single, tended to be more sensitive to climate change. This study also discusses the implications for merchandising strategies.
