The purpose of this study is to understand the characteristics of the mathematical modeling tasks and lesson designs developed by pre-service teachers based on the inherent awareness of mathematical modeling, considering the importance of creating a task to perform mathematical modeling activity and designing a lesson. As a result, the mathematical modeling tasks developed by pre-service teachers mainly presents an appropriate amount of information using real life contexts for the purpose of learning using concepts, and it showed a tendency to develop to the level of cognitive demand that required procedures with connections to understanding, meaning, or concepts. And most of the developed modeling task-based lessons showed a tendency to design warm-up activity, model-eliciting activity, and model-exploration activity. This result is due to the lack of experience of pre-service teachers in creating mathematical modeling tasks. Therefore, it is necessary to continuously provide opportunities for pre-service teachers to learn concepts or create mathematical modeling tasks intended for exploration according to various mathematical contents, thereby actively cultivating their ability to create modeling tasks in the course of training pre-service teachers. Furthermore, it is necessary to strengthen the expertise in mathematical modeling teaching and learning by providing opportunities to actually perform the mathematical modeling-based classes designed by pre-service teachers and to experience the process of reflecting on the lessons.

Section design of vehicle structure has been developed by two methods. One is the section property method which uses section property as a design variable. This method shows the tendency of an optimum section approximately. The other method is the section shape method which utilizes geometric parameter of section as a design variable. Practical solutions are obtained by this method. However, it is very expensive for large-scale problems due to the large number of geometric parameters. These two methods are compared through several sample problems. The finite element method is used for the structural and sensitivity analyses. The results are analyzed based on the number of function evaluations, the quality of cost function, the complexity of programing, and etc. The applications of both methods are also discussed.

With the rapid progress of the aging society in Korea, the silver generation is emerging as another class of users in the new population structure. This is a social issue to be dealt with, and the effect of such a change is being observed dearly in the design area. In addition, there are increasing demands for consideration of minor groups of users including the elderly, the disabled, the left-handed, children and pregnant women and nursing mothers, who have been treated as the weak. Such a human-centered idea may be the manifestation of the recovery of humanity and the self-realization of human beings through experiences and reflections of the industrial society of the past. The present study examined the tendency of design standardization centering on universal design, which has emerged in response to user-centered social needs, and suggested general considerations for the necessity of introducing such standards. These days the meanings of standardization are not limited to quality, performance, safety and economic aspect. Standardization is required to consider the diversity and the welfare of human beings. In addition, one of the important functions of standardization is to provide designers with important clues and guidelines for designing. In reality, however, standardization has been rejected by the circle of design for the reason that it deters free creation, so research on the introduction of standardization has been at standstill. As ISO/IEC Guide71 was published in November 2001, based on which, the Korea Standards Association established KS A ISO/IEC Guide71 without changing its contents. In companies' manufacturing activities, the progress of standardization in connection to universal design is growing more important. However, usefulness and interchangeability for the absolute majority resulting from standardization are incomparable. Lastly, the realization of universal design requires human-centered design mind, based on users' experiences and needs, the characteristics of the human bodies and inconvenient elements rather than standards for the sake of standardization.

The purpose of this study was to find the characteristics of the exhibition space planning methodology as 'Spatialization of Knowledge' through analyzation of the spatial structure in the contemporary museum architecture. The result of this study is expected to apply in designing an exhibition space and may become a target point. Further more this study can result a museum design to assist actual museum to fully function and play a role as a service facility for users by containing broad knowledge and fair understanding of user's needs in museum planning. Basic survey of museum architecture history will help visualizing conceptual structure of the museum exhibition and the 'Space Syntax' method has been used to make this conceptual data more objective. This study found that the contemporary museums most likely to include in its planning the various spatial organization in order to convey knowledge. The result reflects the needs of modern society which shows the design accepting individuality in society with variety of needs. And this also explains that museum space organization has to reflect various ways or methods of conveying knowledge. In addition, users have tendency to prefer more open space organization for easy access and approach in exhibition environment. It is clear to see the change in today's viewing pattern that the users prefer flexible exhibition space where they can be more proactive in receiving knowledge by following their own circulation over architecturally constrained circulation pattern within the exhibition area.

The purpose of this study was to investigate the differences in various fashion lifestyle segments' perceived benefits and design preferences for outdoor clothing to improve the development of outdoor clothing. Data were collected by questionnaire from 600 subjects aged 30 years and over with experience purchasing outdoor clothing in the past year. Frequency analysis, factor analysis, cluster analysis, reliability analysis, ANOVA, and chi-square analysis were used for the data analysis. The results of this study were as follows. Four segments were identified based on fashion lifestyle: manifoldly conscious, sensation conscious, practicality conscious, and brand conscious. Perceived outdoor clothing benefits generated three dimensions, including premium brand, practicality, and functionality, and preferred image produced two factors, tasteful/refined and comfortable/casual. Significant differences were found in the purpose of purchasing outdoor clothing, perceived benefit, and image and t-shirt pattern design preference among the segments. The manifoldly conscious group had a higher tendency to pursue various benefits and images of outdoor clothing and to prefer t-shirt textile designs with foulards and stripes. The sensation conscious group considered fashion and individuality in daily life but not in outdoor clothing. The practicality conscious group showed a preference for simple and casual styles with functionality and foulard patterns for t-shirts. The brand conscious group tended to prefer a striking design to functionality. This study is expected to be used as preliminary data for merchandising planning of outdoor clothing.

Contemporary fashion emphasizes artistic, decorative aspects beside functional, practical targets, and pursues various materials. Also, rising of the design-based tendency, using the various tonality, texture and unveiling the new processing method, decorating technology and a new-material have made the ornaments as one of the figure that expose aesthets and individuality of designers and owner. With its unique expression and artistic beauty the design of ornament pervaded their field to figurative arts. This study aimed at the weaving technique using a hooked needle which is a crochet, and the making manufactured skirts item, moreover the study focused on putting the skirts item into the ornaments of the crochet. The skirt, which was thought to belong to women only, made easy and economic goods. Consumer also wanted to feel free and comfortable as manufactured items did, and it added individuality and practical use. This research tried to develop the design of crochet items to supplement the higher value-added, after examining the theoretical background of crochet, and analyzing crochet trend from 2005-06 F/W to 2010 S/S. As the result, it could be seen that the crochet may offer contemporary ornament art expressing formativeness of handcraft and fineness to the era of replica and manufactured goods.

Purpose - This study empirically analyzed the effect of the customer orientation in Insurance Salespersons on the perceived referral risk and referral intention. In the empirical study, we try to provide suggestions for reducing the perceived referral risk of customer oriented selling activities and improving the referral intentions according to customers' tendencies. Research design, data, and methodology - Data collection was conducted through the convenience sampling method for customers who had insurance coverage for about two months from March to May 2015. A total of 700 copies were distributed and 670 copies (95.7% recovery) were collected. Finally, 661 copies were used for final analysis. With the IBM PASW 22.0 statistical program. The interaction effect for the hypothesis test was generated by multiplying the average centralized independent variable and the control variable, and the average centralization variable was used to minimize the multi-collinearity problem of the interaction effect between the independent variable and the control variables. Results - Hypothesis 1 was adopted because the effect of customer-oriented selling activities on perceived referral risk were significantly negative. The effect of customer orientation on perceived referral risk is affected by innovative tendency, risk-taking tendency, and interpersonal tendency Interaction effect was observed. Therefore, Hypothesis 2-2, Hypothesis 2-3, Hypothesis 2-4 were adopted. The effect of customer-oriented selling activities on referral intention was significantly positive, and Hypothesis 3 was adopted. The effect of customer orientation was influenced by the interaction effect of innovative tendency. Therefore, only Hypothesis 4-2 was adopted. Finally, the effect of perceived referral risk on referral intention was significantly negative and hypothesis 5 was adopted. Conclusions - This study suggests that it is important for the salespeople to grasp the customers' propensity in consideration of the perceived referral risk and referral intention according to the moderating effect of customer orientation. In this study, we showed that customer-oriented selling activities positively influence referral intention by inducing perceived referral risk in customers with stronger risk-taking tendencies. It is thought that it will be an important basic data in designing a customer's selling strategy or conducting selling activities.

This research is a study on the spatial organization of Korean houses designed by architects. It is focused on the characteristics and transformation of spatial organization of house designed since 1970. The variety and regularity of organization existed at the back of spatial structure of Korean houses were analyzed through typological and topographical theory. The general subject of this study is to find out the characteristics and tendency of transformation of spatial organization of houses designed by Korean architects. As a result of this study it was clarified that the spatial organization of architect's house turned its derection from the concept of 'unification and connection' to that of 'separation and segregation' It also was found that the degree of depth of room has been increased and the degree of concentration to a certain room has been decreased through the passing of time. It is because of the trend of spatial separation of rooms appeared in the architect's houses.

Nowadays minimalism has influence on Korean Architecture and Interior Architecture at the turning of new generatiov. Minimalism is a plural phenomenon that has developed from Modernism to Contemporary but there is the tendency to define minimalism within Architecture and Art. Also it is a fact that there are many disordered minimal aspects in Architecture. This study is started from accurate understanding the mistakes in the field of Interior Architecture, that are brought by the elapse of time, and analogizing the circumstances of Interior Architecture in the field of Architecture. Especially the purpose of this study is to grasp the relation between the minimal characteristics of Korean traditional Architecture and the stagnancy of Korean Architecture. Under the assumption that the characteristics of minimalism exist in Korean tradition, this study contents the characteristics of minimalism in western modernism to analyze the contemporary Korean Architecture and interior Architecture that the assumption is appled to.
