The evaluation of the Fuzzy Expected Value (FEV) as a typical value requires complete knowledge about the domain of the evaluation, and the distribution of the population in that domain [1]. Since in many situations it is not possible to gather complete knowledge regarding the domain, it is necessary to relax some of the restrictions involving the evaluation of FEV. In this paper we discuss solutions to this problem by using the concept of the Fuzzy Expected Interval (FEI).

This study is intended to identify the difference in social skills among adolescent students, by grade gender, rights practice, and self-awareness. It will raise awareness of the importance of the rights of adolescents and provide basic data of guaranteed rights for adolescents and social skills. Using questionnaires, a 569 adolescents, in four middle and high schools in Seoul and the Capital Area, were analyzed. The study results were as follows: first, females showed higher empathy skills than males did in social skills. In the case of male adolescents, self-control skills among social skills, was higher than those of females. Second, practice for rights and self-concept had positive influences on social skills. The higher the practice for rights, the higher cooperation, assertiveness, empathy, and self-control the adolescents had. The more positive self-concept of physical appearance, gymnastic ability, friends, and honesty, trust and value, indicated a higher assertiveness. The result implied that the adolescents' practice for their rights, self-concept, and social skills were highly correlated with one another, and adequate practice for their rights and positive self-concept had influences on their social skills. Based on the results, in order for adolescents with a low level of social skills to have a satisfactory social life, they should be encouraged to practice their own rights in the right direction and to acquire positive self-concept in the future.

This study proposes a mathematical model to estimate the economic value of weather forecast service, among which the precipitation forecast service is focused. The value is calculated in terms of users' satisfaction or dissatisfaction resulted from the users' decisions made by using the precipitation probabilistic forecasts and thresholds. The satisfaction values can be quantified by the traditional value score model, which shows the scaled utility values relative to the perfect forecast information. This paper extends the value score concept to a collective value score model which is defined as a weighted sum of users' satisfaction based on threshold distribution in a group of the users. The proposed collective value score model is applied to the picnic scenario by using four hypothetical sets of probabilistic forecasts, i.e., under-confident, over-confident, under-forecast and over-forecast. The application results show that under-confident type of forecasts outperforms the others as a measure of the maximum collective value regardless of users' dissatisfaction patterns caused by two types of forecast errors, e.g., miss and false alarm.

In this study, a process is proposed to calculate analytical correction values for the vertical shortening of all columns on all floors in a high-rise building that minimizes the error between the structural analysis predictions and values measured during construction. The weight ratio and the most probable value were accordingly considered based on the properties of the shortening value analyzed at several points in each construction stage and the distance between these measured points and unmeasured points at which the shortening was predicted. The effective range and shortening value normalization were considered using the column grouping concept. These tools were applied to calculate the error ratio between the predicted and measured values on a floor where a measured point exists, and then determine the estimated error ratio and estimated error value for the unmeasured point using this error ratio. At points on a floor where no measured point exists, the estimated error ratio and the estimated error value were calculated by applying the most probable value considering the weight ratio for the nearest floor where measured points exist. In this manner, the error values and estimated error values can be determined at all points in a structure. Then, the analytical correction value, defined as this error or estimated error value, was applied by adding it to the predicted value. Finally, the adequacy of the proposed correction method was verified against measurements by applying the analytical corrections to all unmeasured points based on the points where the measurement exists.

In the latest furniture design field, we can find mass production with concept of heterogeneity that is made by harmonizing existing object with other object, which has new value. In order to follow the trend in the reality, various design process method that applied concept of Hybrid is attempted by flexibly combining or changing heterogeneous materials, formations or functions such as combination of new material and wood or IT. However, not like other design fields, its research range in furniture design is limited. This study is conducted in order to overcome and supplement problems that are made when these different materials are combined, such as faults or cracks made due to difference of expansion and contraction coefficient, lack of intensity and change of formation due to external temperature and humidity. Panels that are combined for this study were verified materials that have passed environmental adaptation test throughout the period of 1 year and 2 months, which will be made into a table. By doing this, this study will be an empirical study that establish concept of furniture made with acrylic and provides manufacturing method of combining wood and acrylic. Finally it proposed a new furniture design method that follows the trend by researching new materials with the new concept.

This study investigated adolescents' shopping orientation and price perception according to socio statistics and their experience of internet shopping mall. We distributed the questionnaire to 411 high school students in near Seoul. In the order of high shopping orientation, they showed 'compare products', 'enjoy as leisure', 'shop loyalty', 'discount shopping', and 'brand shopping' orientation. In the order of high price perception, they showed 'economic', 'value', 'brand-quality', and 'price knowledge'. The higher in 'shop loyalty', 'enjoy as leisure' in the shopping orientation, the higher in the price concept of 'price knowledge'. Adolescents who have experience to shopping through internet shopping mall, have the higher enjoy as leisure, shop loyalty, compare products' in shopping orientation, and the higher 'economic, price knowledge' in price perception than those who have not. Socio-statistics parameters are found to affect adolescents' shopping orientation and price perception. Adolescents had average scores in 'shop loyalty', while they had high scores in 'compare products'. Thus, in order to have superior position in adolescent's market, detailed product specification and information are necessary to enhance their shop loyalty. Adolescents thought the price was economical, and they had less concept in 'price knowledge' due to their position. Unlike adults, adolescent's gender does not have effects on their 'economic concept. Male students also had high scores in 'economic concept' as much as female students did.

A leisure culture in the modern society is the measure of a value in one's life and has a symbolic meaning which reflects the aspect of a society where an individual belongs to. Therefore, the leisure is not a simple pleasure but has an critical meaning of expressing the culture of a country. In particular, the theme park leads the public amusement in the modern society using the cutting-edge equipments on a large scale in the postmodernism society being lead by the public. Nonetheless, Korea imports the theme parks of the same type as the Disney land of the Western Europe so that Korea depends on the foreign country in the leisure field. Therefore, in this study, the basic property of the theme park is investigated and the issues of Korean theme park will be revealed through the comparison of Korean theme park to foreign theme parks. In order to solve these issues, it points out that the concept of Korean traditional leisure space has inclusive and upgraded characteristics with many meanings, compared with the concept of the leisure space of foreign countries. . Based on this, the new concept of Korean theme park's space will be proposed. Specially, it is empathized that Korean own originality and credit should be preserved and Korean traditions should be succeeded.
