Systematic modeling methods. which can correctly represent user requirements, are absolutely required to extract components when developing components. But, components are designed and developed In general based on the concept of object modeling so that they lacks in supporting representing cooperation and interaction as well as reuse. It means extracting components is not easy to be applied to complicated and sophisticated large-scale systems. This paper utilizes a role modeling method based on the role of objects, not on objects themselves, to complement object modeling. The Role modeling can break down a complicated system into simple models through abstracting the pattern of objects based on roles of the objects. In this study, an UML-based method extracting components through role modeling is embodied. UML can represent models from various standpoints so that role models arc also viewed from several points of view.

This study aims to understand the concept of 'ruralism' in Korea by comparing with 'rurality' which were dealt with in various fields related to rural areas in Korea. This study conducted a systematic literature review as a methodology. The process is defining key questions, searching for documents, classifying documents, extracting data, and presenting results. The key questions were set to 'How has the term 'ruralism' been used in various studies?' and 'How can the concept of rurality in Korea be organized?' according to the purpose of the study. The study retrieved literature by searching on Korean academic database, RISS and DBpia, using the five keywords '농촌성', '농촌다움', '농촌다운', 'Rurality,' and 'Ruralism.' The search yielded 1,014 documents which were thereafter screened by systematic literature review process. After sifting, only 31 publications were found suitable for inclusion in the final analysis. This study organized them into four categories: rural concept, rural landscape, rural tourism, and rural development. The literature divided into four types. Type I is a study that deals only with economy·society among studies related to rurality, Type II is a study that deals with both the economic·social and physical environment, Type III is a study that deals with the physical environment of a rural area and presents the rural planning principle as maintenance and preservation. Finally, Type IV is a study that presents ruralism as a new rural planning principle for a future rural area. In the end, the study discussed some implications on defining ruralism in Korea.

This study aims to analyze the design concepts of Libeskind's Jewish museums through their comparisons for figuring out his design intentions and characteristics in the realization process. Libeskind's realized four Jewish museums are chosen for this study. For more concrete study, their extracting and application process are also reviewed. The comparison of his museum designs can be good examples in that they show different design approaches on the same architectural type, Jewish museum, to tell their something in common from differences. He could realize his architectural thoughts and configuration methods made by experimental drawings for the first time as real buildings through a series of Jewish museum projects. The commonness of Libeskind's Jewish museums lie on their sharing design concept of Jewish 'history and memory', especially Holocaust, and realized as in contrast to surroundings and 'labyrinth' of spatial configuration to maximize spectator's experiences. As Libeskind regards museum architecture as a carrier of 'time and place', he tried to reflect surrounding context including places, cities, persons and events about museum programs. As a result, unprecedented museums which are not related to traditional museum systems about circulation and spatial configuration are suggested for users to experience Jewish life and history through architecture.

The humanoid creatures like Na'Vi in 'Avatar' remind the audience of a few actors' faces in the movie, enhance realism in film through combining CG and Live action which are related to the story. The design of face-recognizable humanoid creature is expected to be used in many ways; not only in film, but also in newest media. This research proposes to apply the main concept of Caricature which is 'exaggeration' of distinctive face elements from their prototypes for 'likeness' with the subjects. Also, it provides the idea of extracting the distinctive features of a face and combining the exaggerated subject as those features with an imaginary creature-other species, alien, etc. Finally, it proves the effectiveness of the design process with some experiments.

This study is intended to make a tool which can identify how consumers consume by presenting a concept of "consumption style" and by developing the scale to measure it. In order to study the scope and meaning of consumption for modern consumers, "the meaning of consumption" was theoretically considered. Based on it, the concept and perspective of 'consumption style'was formed and then the scale for measuring it was developed. To develop the scale, the scale was formed by extracting questions through a literature survey, and verifying validity through experts' opinion. Then, the final scale was developed by conducting a questionnaire survey for consumers. A preliminary 150- item scale was developed through a literature review. 1000 consumers responded to an online survey using the preliminary scale. This research was made with the intention of not only supplying the academic data on the consumer's "consumption style" but also understanding the consumer's basic behavior patterns. Then A series of tests, such as test-retest, item-to-total correlation, Cronbach's reliability coefficient and factor analysis, were conducted using the survey data. The final scale with 68-items was constructed in the end. The "consumption style" Scale for Consumers consisted of 4 factors.

Material failure behavior is generally dependent on loading rate. Especially in brittle and quasi-brittle materials, rate dependent material behavior can be significant. Empirical formulations are often used to predict the rate dependency, but such methods depend on extensive experimental works and are limited by practical constraints of physical testing. Numerical simulation can be an effective means for extracting knowledge about rate dependent behavior and for complementing the results obtained by testing. In this paper, the failure behavior of a brittle material under different loading rates is simulated by molecular dynamics analysis. A notched specimen is modeled by sub-million particles with a normalization scheme. Lennard-Jones potential is used to describe the interparticle force. Numerical simulations are performed with six different loading rates in a direct tensile test, where the loading velocity is normalized to the ratio of the pseudo-sonic speed. As a consequence, dynamic features are achieved from the numerical experiments. Remarkable failure characteristics, such as crack surface interaction/crack arrest, branching, and void nucleation, vary in case of the six loading cases. These characteristics are interpreted by the energy concept approach. This study provides insight into the change in dynamic failure mechanism under different loading rates.

Due to the increasing use of very large databases, mining useful information and implicit knowledge from databases is evolving. However, most conventional data mining algorithms identify the relationship among features using binary values (TRUE/FALSE or 0/1) and find simple If-THEN rules at a single concept level. Therefore, implicit knowledge and causal relationships among features are commonly seen in real-world database and applications. In this paper, we thus introduce the mechanism of mining fuzzy association rules and constructing causal knowledge base form database. Acausal knowledge base construction algorithm based on Fuzzy Cognitive Map(FCM) and Srikant and Agrawal's association rule extraction method were proposed for extracting implicit causal knowledge from database. Fuzzy association rules are well suited for the thinking of human subjects and will help to increase the flexibility for supporting users in making decisions or designing the fuzzy systems. It integrates fuzzy set concept and causal knowledge-based data mining technologies to achieve this purpose. The proposed mechanism consists of three phases: First, adaptation of the fuzzy membership function to the database. Second, extraction of the fuzzy association rules using fuzzy input values. Third, building the causal knowledge base. A credit example is presented to illustrate a detailed process for finding the fuzzy association rules from a specified database, demonstration the effectiveness of the proposed algorithm.

The purpose of this study is to present the direction for effective public environment design by becoming aware of the social, cultural and historical values that are inherent to the specific regions once again. Concept of regions' sense of identity, regions' resources and regionality were identified as a means based on the basic cityscape plan and guideline for public design. Sample city was analyzed by extracting the regionality elements, and the results are as follows. First, appropriateness of the direction for the public environment design based on the regional identity was confirmed. The need to establish regional identity in the cityscape plan is specified when it comes to the basic goal, strategy and direction. Second, public environment design should be planned within the context of the cityscape. It is necessary to improve with integrated plan by setting up the consistent goal, direction and detailed guideline based on the basic concept of cityscape plan. Third, 'design city' requires the development of the unique design and planned techniques based on the harmony with the existing resources. It is necessary to uncover the powerful design elements that are exclusive to specific regions, and to search for differentiation and visualization to form consensus. Public environment based on regional identity will improve if the above mentioned research results are used as the basic data when it comes to the implementation of public environment design.
