In this paper, characteristics of infrasound and low-frequency noise emission from large modern wind turbines are experimentally investigated. The sound measurement procedures of IEC 61400-11 and ISO 7196 are utilized to field test and evaluation of noise emission from each of 1.5 MW and 660 kW wind turbines using the stall regulation and the pitch control for the power regulation, respectively. It was found that the G-weighted SPLs of low-frequency noise including infrasound shows positive correlation with the wind speeds, irrespective of methods of power regulation. This highlights the potential complaint of local community against the infrasound and low-frequency noise of wind turbines. The comparison of measured data with the existing hearing thresholds and criteria curves shows that it is highly probable that the low-frequency noise from the 1.5 MW and 660 kW wind turbines in the frequency range over 30 Hz leads to the psychological complaint of ordinary adults, and that the infrasound in the frequency range from 5 Hz to 8 Hz causes the complaint by rattling the house fitting such as doors and windows.

The questionnaire which was based on the characteristics of psychological and physiological symptoms of Hwabyung patients was distributed to Hwabyung patients and normal control group. The following results were obtained. 1. It was observed in this study that the rate of occurrence of Hwabyung was higher in female and the people with lower economical and educational background. And this result was in accordance with the previous studies. 2. The personality, defense mechanism and coping strategy of Hwabyung patients was found to be inclined to yin(陰) disposition in this study. 3. Family life of Hwabyung patients was found to be worse than that of normal control group in every respect. 4. In terms of evaluation of their lives, the emotion of Hwabyung patients was characterized as Hahn(恨). And it is postulated that this emotional complex falsifies the reaction of Ki(氣) to the seven emotions(七情).

Purpose: After abortion, many women could have psychologic problems and physical symptoms. But in Korea, the symptoms and psychologic problems and after abortion had rarely been researched. Methods: The subjects were 29 women who visited Kangnam Korean hospital for postabortion management from May 2007 to December 2007. From questionnaire, we researched the variable symptoms after abortion and depression as Edinburgh Postnatal Depression Scale. Results: The 79% of patients took a rest only less than 1 week after abortion. As the rest time was shorter, the number of symptoms was higher. The frequent symptoms were related to the dysfunction of autonomic nerve system and the circulating system. The patients after abortion had high Edinburgh Postnatal Depression Scale scores, the mean score was $13.33{\pm}7.11$. The high EPDS scores and the number of symptoms was related with methods of abortion and age. Conclusions: Postabortal symptoms are related with physical symptoms and depression. So psychological evaluation would be needed. And for prevention of postabortal symptoms, the adequate rest time would be demanded after abortion.

In order to analyze travel mode choice behavior, behavioral models including logit model, based on revealed preference theory, have been using easily measurable variables such as individual socioeconomic characteristics and physical attributes of travel modes. But some recent attitudinal models of travel choice behavior have implied that the negligence of individual psychological variables and individual choice constraints in travel mode choice might preclude better prediction of individual travel mode choice behavior. In this context, this study was attempted to reconstruct an attitudinal model(AM), especially focused on the decision rules in travel mode choice decision making process, consistent with the conceptual framework relating individual attitude and choice constraints to choice behavior. And to evaluate the strengths of the AM to other comparative models(logit, linear-additive, conjunctive, lexicographic model) in predicting travel mode choice bebavior, an empirical study of the mode choice in work-trip to CBD in Seoul was performed. According to the results the percent of correct prediction(PCP) derived from the AM was higher than those derived from comparative models by at least 7 to 20% in predicting travel mode choice. But each model produced a different prediction accuracy depending on market segmentation by travel modal users, individual socioeconomic characteristics, transportation system characteristics, and satisfaction levels. The finding that different groups divided by a certain criterion employ different decision rules supports the necessity of developing a choice model such as the AM combining compensatory and noncompensatory decision rules, and suggests that a proposed transportation system management plan or policy may have different effects on each group.

Price is a product attribute, which is determined by the function of the producing cost and profit. It is also identified as one of the most important components of the marketing mix. For consumers, price is an always-existing cue, definite evaluation criteria, and easily accessible information in the purchasing process. Considering the concept of the clothing-price in a comprehensive perspective encompassing economic, psychological and marketing perspectives, a theoretical model was developed. The model includes souses and dimensions of price perception and related behaviors. Souses of price perception were: the actual retail price at selling point, the internal reference price and external reference price. The dimensions of price perception included sacrifice perception, economic value perception, inference, savings perception and price as information perception. Clothing price related behaviors that flowed these dimensions were: low price consciousness, value for money consciousness, price-quality inference, price-prestige inference, sale proneness and price mavenism. An empirical study was conducted to validate the theoretical model. A questionnaire was developed and data were collected from 680 adult women living in Seoul, Korea. Confirmatory factor analysis as well as exploratory factor analysis results showed that theorized price related behaviors were successful classifications.

This paper explored the impact of dynamic geometry software such as CabriII, GSP on student's understanding deductive justification, on the assumption that proof in school mathematics should be used in the broader, psychological sense of justification rather than in the narrow sense of deductive, formal proof. The following results have been drawn: Dynamic geometry provided positive impact on interacting between empirical justification and deductive justification, especially on understanding the necessity of deductive justification. And teacher in the computer environment played crucial role in reducing on difficulties in connecting empirical justification to deductive justification. At the beginning of the research, however, it was not the case. However, once students got intocul-de-sac in empirical justification and understood the need of deductive justification, they tried to justify deductively. Compared with current paper-and-pencil environment that many students fail to learn the basic knowledge on proof, dynamic geometry software will give more positive ffect for learning. Dynamic geometry software may promote interaction between empirical justification and edeductive justification and give a feedback to students about results of their own actions. At present, there is some very helpful computer software. However the presence of good dynamic geometry software can not be the solution in itself. Since learning on proof is a function of various factors such as curriculum organization, evaluation method, the role of teacher and student. Most of all, the meaning of proof need to be reconceptualized in the future research.

This study investigates consumer's traits of market segmentation based on the apparel benefits. The subjects were 302 college students living in Yunnam, China. The mean, ANOVA, factor analysis, Duncan test, and K-means cluster analysis were used for statisticals analysis. The results of this study are as follows. The college students were classified, into six subdivisions, according to the apparel benefits by cluster analysis: indifference group, utility pursuit group, hedonic/brand pursuit group, individuality pursuit group, social recognition/fashion pursuit group, and pursuit benefits-minded group. In the factors of happiness-pursuing and life-centered of materialism, significant differences were found according to the groups of apparel benefits, and all factors of symbolic consumption and brand loyalty were found to have significant differences according to the groups of apparel benefits. The evaluation criteria of clothing were significantly different, depending on apparel benefits subdivision in criteria of aesthetic, socio-psychological, and utility. The use of information was shown to have significant differences, according to the groups of apparel benefits. The study results are highly expected to be utilized as useful sources in marketing plans for the midwest of China.

This study aims to recognize that creative thinking methodologies can be adopted in the spatial design. The concept of 'Convergent' and 'Divergent' used in structure of intellect model by Guilford is chosen to understand the character of creative thinking methodologies. Technical and physical contradictions is analyzed for '40 inventive principles' of TRIZ and spatial design works. Through this study, we recognize that the creative thinking methodologies consist of analysis, idea generation and evaluation phase. The psychological inertia that limits the creative thinking should be move away from solving problem, and convergent and divergent thinking have peculiarities to be adopted in condition and to be harmonized, and to set the direction of solving technical problems through to reach the target point integrated way of thinking is needed. '40 inventive principles' by Altshuller are based on engineering and useful in many areas of fields. However some principles are not accepted in design process because these are not considered in design field and paradigm is changed from machine to nature. Nowadays, nature is a prime issue for sustainable human life, because it has sustainable recycle structure and saving energy ways. Thus, creative thinking, including TRIZ is useful in design education and progress, and should be an essential element to get a new design paradigm.
