  • Bates and Watts (1981) have discussed the problems of reparameterizing nonlinear models in obtaining accurate linear approximation confidence regions for the parameters. A similar problem exists with computing confidence curves for fitted values or predictions. The statistical behavior of fitted values does not depend on the parameterization. Thus, as long as the intrinsic curvature is small, standard Wald intervals for fitted values are likely to be sufficient. Accuracy of linear approximation for fitted values is investigated using confidence curves.

  • In estimating designed architectural buildings, many factors in various design domains such as function, structure, form, environment may be considered and then a building design might be selected or modified as final design from many possible design results. This paper proposed a method to obtain complexity values from two dimensional drawings which are floor plans or elevations. The Complexity values could be turned into esthetic values. The method has been developed based on information theory, shape pattern representation and cognitive theory. Results of measuring complexity value can make the computer evaluate and select final results produced from automatic design processes by the computer That is to say, aesthetic values based on order and chaos can be measured using complexity values and then some results having superior values can be selected as final result. Also some cognitive processes as perception of two dimensional drawings are discussed using shape representations. Aesthetic values could be varied in terms of shape properties such as size, individualities and knowledge as well as order and chaos.

  • This study aimed to investigate the associations between clothing consumption values and the ambivalent clothing consuming behavior of young female adults. To explain the ambivalent consuming behavior prevailing in the contemporary fashion market, five dimensional consumption values proposed by Sheth(1991) were adopted as explanatory factors, and fashion leadership and spending were included as moderating factors. Data collecting using written survey instrument yielded one hundred and seventy two complete responses from female consumers aged between 20 and 39. Factor analysis on clothing consumption values resulted in five dimensional structures of consumption values for the sample: expressive, epistemic, functional, social, and fashionable values. Among these, expressive, functional, and social values significantly affected ambivalent consuming behavior. The effect of expressive value was strong regardless of fashion innovativeness, opinion-leadership, and monthly income of consumers, however, the effects of epistemic, functional, and social values were changed depending on the moderating factors.

  • This paper explored undergraduates' LoHAS purchasing behavior and factors influencing the behavior, including' self-construal, and LoHAS values, attitudes and behavior. First, this study investigated how self-construal affected LoHAS values, and then analyzed how LoHAS values influenced LoHAS attitude and behavior. We administerd a survey with undergraduates attending a university located in the metropolitan area. The analysis results indicate that ecological self-construal affects LoHAS values. According to the analysis, both environmentalism and sustain ability of LoHAS values also affect LoHAS attitude, and then the attitude influences LoHAS behavior. This study shows the casual relationship between variables including self-construal, LoHAS values, attitude and behavior. In particular, this finding confirms that self-construal as one of psychological factors affects LoHAS consumers' values and behavior.

  • In order to optimize designing process of corrugated fiberboard boxes for agricultural products, first of all, compression strength of each liner were experimentally evaluated on the various conditions of relative humidity and analyzed by liner regression analysis. At the 66 percents of relative humidity, IK(imported kraft liner) liner board lost little of its compression strength compared to others. At the relative humidity 93 percents, KA liner board lost its compression strength only 40 percents while SK liner board lost up to 56 percents. From the result of prediction modeling of ring crush strength in various humidity conditions, R square values were ranged from 0.59 to 0.97. At 56 percents of RH or below, R square values were relatively low, but at 66 percents of RH or higher, the values were 0.85 or higher. The significance values were lower than 0.001 at every RH condition. Level of significance of experimented values was about 80 percents of predicted values and R square values were between 0.89 to 0.95.

  • The purpose of this study was to explore factors influencing on work values of female college students focusing on parental effect to enhance their participation in labor market. The respondents were asked to answer a questionnaire, and the collected 400 data were analyzed using SPSS 23.0. The results showed that the students and their parents had more leisure-oriented and extrinsic work values than labor-oriented and intrinsic work values. The labor-oriented and intrinsic work values appeared to be high in the group with experience of part time jobs, with high educated father or with middle household income. The influencing factors on college students' work values were parental work values, gender consciousness, self-efficacy and major. The results from this study suggest that parents of college students should be educated to change their work values.

  • The purpose of this study is to understand consumer values derived from products by the contemporary consumers, as the meaning of a product is extended from the functional utilities to the mediums of fulfilling consumer values. Consumer values have been researched from the marketers' perspectives and, thus, the scales to measure consumer values tend to be too abstract and not always reflective of the consumers' perspectives. Holbrook's typology of consumer values is utilized and the products are classified into four groups according to the product characteristic of the utilitarian versus hedonic, and the consumption spaces of the indoor and outdoor. The findings are as follows. First, the values of efficiency, excellence, ethics, and spirituality are more likely derived from utilitarian products, while the value of play is more likely derived from the hedonic products. Second, the values of efficiency, excellence, and ethics are more likely derived from the indoor products, and values of playfulness, esthetics, status, and respect are more likely derived from the outdoor products. Third, the most frequently mentioned values are the efficiency, playfulness, and status. Fourth, the list of products answered as being representative for four types of products are short to include obvious products such as TV, mobile phone, computer, car, refrigerator, and MP3 player. Both the utilitarian and hedonic values are derived from TV, computer, and mobile phone, while the utilitarian value from refrigerator and car, and the hedonic value from MP3 player, digital camera, and game consoles. The results imply that consumer values should be carefully understood and reflected in developing new products in order to successfully fulfill consumers' underlying needs and requirements.

  • Individual values exert strong influence on attitudes, behaviors and lifestyles of a person. Furthermore, Individual values predict personal world views and can predict behavior and behavioral predispositions in the organization. So, individual values influence the organization strongly. And, organizational culture in police is affected by the values of police officers. The aim of this study is to make use of the theory of human values developed by Rokeach as a theoretical framework to evaluate value preferences among police officers in Korea and have a thorough grasp of the point of sameness and difference with two studies. In this study, I analyze data and make a comparative study of values with preceding studies I find that police officers regard personal values as more important than social values. A noticeable finding of this study is the middle ranking of the value of equality among police officers. It's different result with other studies. And, the value of national security is the low ranking among police officers. It's the same result with preceding studies.

  • While research projects and reports on values in mathematics education increased in the international community over the years, little has been known about the topic and research findings in South Korea. The purpose of this study was to analyze the trends of value research in mathematics education focused on the "mathematical values" and "mathematics educational values" as defined by Bishop (1996) through a systematic review of the literature. A total of 66 research papers related to value research were analyzed in terms of the following four areas: research period, projects, target research population, and research method. The results of this study showed that the value research that was carried out was project-driven. There was an increase in both the number of papers published and countries that were studied, which encouraged the continuous expansion of the field. Furthermore, the topic of mathematics educational values was studied more than mathematical values. It was also observed that the survey method, among others, was frequently used to explore mathematics educational values of middle school teachers. Finally, research methods related to the measurement of value were gradually refined over time. Based on these results, this paper describes implications to conduct and advance value research in South Korea in various aspects, including in the field of mathematics education.
