Recently, following the commercialization and market entry of smart clothes with diverse functions, smart clothes have been changing from technology-centered products to user-centered products. However, the analysis of consumer demand centered on actual commercialized products is lacking. Therefore, this study classified commercialized smart clothes by function and analyzed the demand and requirements of smart clothes according to sports/outdoor clothes consumption behaviors. As a result, consumers were classified according to their sports/outdoor clothes consumption behaviors into an outdoor leading group with high consumption propensity, an outdoor pursuit group with medium consumption propensity, and an outdoor following group with low consumption propensity. Among the commercialized smart clothes, those with a heartbeat measuring function, those with a heating function, and those with a light-emitting function were presented and demand analysis was conducted. According to the results, the outdoor leading group and the outdoor pursuit group had higher levels of awareness, preference, and purchase intentions than the outdoor following group. In addition, the outdoor leading group showed the highest level of purchase price acceptance while the outdoor following group showed the lowest level of purchase price acceptance. However, this study has a limitation that the acceptance for smart clothes were analyzed with consumers who had experience in sports outdoor clothes consumption. Therefore, in future, studies will be conducted with a wide range of consumers.

The purpose of this study is to investigate the effect of STEAM program on students' academic achievement, creative problem-solving ability, scientific inquiry ability and scientific interests of elementary school students. For this, we developed a STEAM program to utilize animation production about 'structure and function of the our body' unit in 5th grade. The STEAM program was developed for a total of 9 sessions and was applied to the experimental group. The theoretical lesson of the 2009 revised curriculum was consisted of 11 sessions and was applied to the comparative group. The results of study showed significant differences of the students' academic achievement, creative problem-solving ability to the experimental group participating in the STEAM program and also showed significant effects in the domains of subject contents and teacher preference, which are the areas of scientific interests compared to the comparative group. This means that the STEAM program to utilize animation production about 'structure and function of the our body' developed in consideration of the characteristics of elementary students positively influenced the academic achievement, creative problem-solving ability and scientific interests of elementary school students. In the future we need to develop STEAM programs more variously that utilize animation production and that it needs to be applied to elementary schools.

A wireless Internet proxy server cluster has to Distillation and Caching functions in order that a user on wireless internet can use existing wired internet service. Distillation function works to distill HTML documents and included images according to the defined preference by a user. When a user requests repeatedly, Caching function decreases response time by reusing original and distilled images or HTML documents. In this paper, we proposed enhanced distillation and caching functions. We performed experiments using 16 PCs and experimental results show the effectiveness of the proposed system compared to the existing system.

Maximum intensity projection (MIP) is a common visualization technique in medical imaging system. A typical method to improve the performance of MIP is empty space leaping, which skips unnecessary area. This research proposes a new method to improve the existing empty space leaping. In order to skip more regions, we introduce a variety of acceleration strategies that use some tolerance given by the user to take part in image quality loss. Each proposed method shows various image quality and speed, and this study compares them to select the best one. Experimental results show that it is most efficient to add a constant tolerance function when the image quality required by the user is low. Conversely, when the user required image quality is high, a function with a low tolerance of volume center is most effective. Applying the proposed method to general MIP visualization can generate a relatively high quality image in a short time.

The purpose of this paper is to develop a space program of the new community center in multi-family housing. The community center defined in this study is a communal facility which integrate cultural and welfare facilities and activity programs into a complex. Through the analysis of the community programs and spaces for multi-family housing community, a new community center program is proposed. And basic area guidelines are proposed through the making of the space modelling of the important area of the center. According to the guidelines, more spaces compared to the present standards and conditions are needed for a new community center. However, the adjustment of area regulation is essential, considering the fast changing trend of resident's social needs. A new regulation system that controls the total area of function spaces of a community center, rather than controlling each function and area, is required. This kind of system makes it possible to decide programs freely within the limit of total floor area regulation by neighborhood's characteristics and residents'preference.

The category for waterproofing is one of construction process most affected by falling-off in price competitiveness, construction quality, and material performance. Therefore, in order to select of waterproofing construction firms, it is necessary to consider Incorporating both price competitiveness and construction quality. In this article, I would like to analyze 10 Factors for Selecting using fuzzy-AHP model, including the survey of the waterproofing experts. This fuzzy-AHP model can be shown to calculate the fuzzy trigonometrical function to reflect weights for preference of 10 factors for the waterproofing construction firms. It was found from the result that waterproofing construction firms was searched order of priority for select by fuzzy-AHP model.

In Taguchi's quadratic expected loss function used as robustness metric of performance characteristics, the mean and variance contributions are confounded. The consolidation of the mean and variance in the expected loss function may not always be the ideal approach. This paper presents a procedure for multi-attributes design optimization, where the mean and variance of performance characteristics are considered as separate attributes having designer's relative preferences for them and Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) is introduced to attain robust optimal design. The effectiveness of proposed approach is shown with an example of a weld line minimization problem in the injection molding process.

The worldwide proliferation of regional trade agreements combined with rising interests of 37countries has led to the emergence of a possible GSTP between each country. Although there are many obstacles to GSTP, its effect, if a realized, will go beyond trade related issues. This study was to specify and estimate a model of Korea-GSTP Ground in Korea that can be used to evaluate and improve management decisions. The development of the model relied on several submodels. On the trade negotiation side, a import demand function was estimated in order to account for the increasing amount of import. In terms of margin of preference(MOP)s, they were used to estimate values after decreasing tax based on scenarios I, II, and III. The results showed that the highest effects for increasing value and amount of import are a freezing crab(HS code 0306143000) and freezing hairtail(HS code 0303793000). This paper will be provide to help policy makers understand the Korea-GSTP Ground in the Korea fishery.

The purpose of the present study was to examine the role of semantic and syntactic knowledge in the first language acquisition of Korean classifiers. The elicited classifiers production test(EPT) was conducted to 105 children aged from 2 to 7. EPT consisted of 16 classifiers and two items for each classifier. 32 items were divided into 2 major semantic features: animacy and inanimacy. The semantic features of inanimacy were subcategorized into 3 features such as neutral, shape and function. The results revealed that; 1) children produced the correct structure of classification from the very early age with correct word order of the noun phrase showing early fundamental syntactic knowledge; 2) The earliest response pattern was to respond to all nouns in the same way using a neutral classifier showing no apparent semantic basis for their choice; 3) Children didn't show any preference for animate, shape, or function classifiers.

Confronting with series of environmental problems. caused by urbanization and the constantly improving consciousness of the entire society towards environmental protection, it has become an inevitable trend to develop parks and green space planning that guided by the principle of 'respecting nature, preferring ecology' and integrate function, arts and culture of landscape design. Aiming at specific project, humanized design should be laid stress on. With fundamental functional construction serving as the base, the reflection of cultural content and regional landscape as the characters, using various landscape gardening elements reasonably to enrich space design as well as highlighting leisure and sport function and following the concept 'human-centered', parks and green space filled with natural vitality and cultural spirit can be constructed, people, city and the nature could develop together in harmony.
