  • The purpose of this study is to identify whether franchisee-perceived franchisor's proactiveness, innovativeness and risk-taking affect franchisee-perceived affective commitment with franchisor, and the affective commitment affects franchisee-perceived external representation and service delivery. Based on total 280 samples obtained from owners or managers of franchise fast-food restaurants in located in Yeongnam province, the research findings are as follows. Firstly, the innovativeness and risk-taking positively affect the affective commitment. Secondly, the affective commitment positively affects external representation and service delivery. But proactiveness does not affect the affective commitment significantly. These findings imply that firstly, franchisor should investigate consumer trends periodically and develop new successful menus and services more than competitors do, and implement new marketing techniques innovatively towards these menus and services. Secondly, franchisor had better adopt high return/risk strategies because of deepened competition and do bold decisions of price change etc. Also, in order to increase proactiveness, franchisor needs to launch new menus and services earlier than competitors and occupy market in advance, which strengthens affective commitment with franchisees. Thirdly, in order to increase affective commitment with franchisees, franchisor needs to match franchisor's value with franchisee's value and same value means same objective. Lastly, limitations and further research directions are also discussed.

  • The purpose of this study was to analyze the uses of the external representations in the $3{\sim}6th$ grade science textbooks developed under the 7th National Curriculum on the basis of the theories and the research results on learning with the multiple representations. The results showed that the frequencies of the macroscopic external representations were higher than those of the symbolic external representations. The external representations with drawing and/or writing, especially writing, were used more frequently than those without drawing and/or writing. However, the most of the external representations were rarely used according to the principles and/or the theories (e.g., personalization principle, dual coding theory, cognitive load theory, and social constructivism theory) for effective uses of the multiple external representations in the science textbooks. The present study provides the guideline to establish the effective uses of the external representations in the science textbooks that not only meet learners but also teachers.

  • Mekuro-Kazoen BLDG. is complex of office, hotel, hotel, and banquet hall, built in 1991, Tokyo, Japan. This building suggest us various issue about the representation of traditionality in current architecture. We can find the possibility of representation of traditionality in large complex, in past, rarely applicated. Even in Japan, such trial in official building as New Office Building of Tokyo in Sinzuku shows a application only in the elevation plan. In Mekuro-Kazoen BLDG. the application of traditionality are fond not only in external appearance, but also in interior design. And the modernity and traditionality in this building are represented simultaneously not deterioating each other. the issues of representation of traditionality in interior design should be succeed not only in now but also in future. The method of application need to be studied and improved. The fields of application also should be extended such as large complex buildings and future-oriented buildings.

  • The purpose of this study was to explore procedures and modalities on collaborative visualization processing of text information for developing e-Learning contents. In order to investigate, two research questions were explored: 1) what are procedures on collaborative visualization processing of text information, 2) what kinds of patterns and modalities can be found in each procedure of collaborative visualization of text information. This research method was employed a qualitative research approaches by means of grounded theory. As a result of this research, collaborative visualization processing of text information were emerged six steps: identifying text, analyzing text, exploring visual clues, creating visuals, discussing visuals, elaborating visuals, and creating visuals. Collaborative visualization processing of text information came out the characteristic of systemic and systematic system like spiral sequencing. Also, another result of this study, modalities in collaborative visualization processing of text information was divided two dimensions: individual processing by internal representation, social processing by external representation. This case study suggested that collaborative visualization strategy has full possibility of providing ideal methods for sharing cognitive system or thinking system as using human visual intelligence.

  • This study aimed to propose a fashion design development method using the external and internal characteristics of the flower and bird paintings in traditional Korean folk paintings. As a research method, external and internal characteristics of folk paintings were examined through previous studies and literature research, and folk painting patterns were developed into digital textile designs. Five 3D digital fashion designs were proposed using the CLO 3D program. The external characteristics of folk paintings were as follows: simplification and planarization of object representation, diversification of viewpoints, ignorance of perspective and symmetrical enumeration, strong colors and contrast effects, and the simultaneous representation of time. The internal characteristics of folk paintings were as follows: symbolic meaning, the beauty of free humor, modest aesthetics, complexity of reality and fantasy, and desire of shamanism. The results are as follows. Firstly, the flower and bird painting was a decorative painting style that emphasized decorative beauty and was suitable for developing fashion designs with Korean originality because of the symbolic and internal meanings. Simple layouts and bold free-spirited representations were effective ways to fill the screen with objects and gave the pattern a decorative effect. Secondly, developing a virtual clothing prototype based on digital design method using the external and internal characteristics of folk paintings and producing realistic fashion designs suggest the integrated use of science and technology, embodying modern fashion through the combination of digital fashion content and traditional cultural content. Thirdly, as a result of the development of 3D digital fashion designs, an eco-friendly and sustainable fashion design methods with virtual clothing can suggest a design development method that saves time and cost in the fashion design process while considering the environment.

  • This study investigated the influences of situational interest, attention, and cognitive effort on drawing as a method to assist students to connect and integrate multiple external representations provided in learning chemical concepts. Seventh graders (N=178) at two coed middle schools were taught about the "Boyle's Law" and the "Charles's Law" for two class hours through drawing. They observed macroscopic phenomena through demonstrations. After these observations, they drew their mental model from the external verbal representation, and then compared their drawings with external visual representation. The tests assessing situational interest, attention, cognitive effort, and conceptual understanding were administered as post-tests. Correlation and path analyses supported a causal model which situational interest had a positive direct effect on attention to the drawing. Attention led to conceptual understanding directly as well as through cognitive effort. These results suggest that situational interest may be induced by drawing first of all, and attention and cognitive effort may be direct causes of conceptual understanding in drawing. Educational implications are discussed.

  • In this paper, we propose a scenario representing method, a specification language, and a verification technique for OARTS(Object based Approach for Real-Time Systems). As well as the general modeling method(event trace diagram), this study includes a specification language and a verification technique because there was no study about methodological level technique for scenario development as yet. Centering around the synchronization problem of transition of external modules which are the communication interfaces based on the objects, we lay stress on the representation of sequence of external events and internal action transitions. From the results of practical experiences, it has been ascertained that the proposed method reflect well the requirements in the analysis step, and its validity of the representation has been identified by a conceptual verifier. We support that it can serve as an analyzing tool for representing a general real-time scenarios also.

  • The purpose of this study was to investigate whether a franchisor's influence strategies could affect a franchisee's relationship satisfaction, which in turn could affect their boundary spanning behaviors. The constructs of influence strategies included promise, recommendation, information exchange, request, threat, and legalistic plea. The boundary spanning behaviors were external representation, internal influence, and service delivery. The sample used for this research consisted of store owners or managers of franchisee restaurants in Korea. A total of 605 questionnaires were analyzed using SPSS/$PC^+$ and LISREL. Empirical research findings were that (1) promise, recommendation, and legalistic plea affected relationship satisfaction, and (2) relationship satisfaction influenced external representation, internal influence and service delivery. However, information exchange, request, and threat did not affect relationship satisfaction. Based on these findings, franchisors were recommended to provide motivations to franchisees if the former wants to receive help from the latter.

  • This paper addresses a new method for constructing surface representation of 3D structures from a sequence of tomographic cross-sectional images, Firstly, we propose cell-boundary representation by transforming the cuberille space into cell space. A cell-boundary representation consists of a set of boundary cells with their 1-voxel configurations, and can compactly describe binary volumetric data. Secondly, to produce external surface from the cell-boundary representation, we define 19 modeling primitives (MP) including volumetric, planar and linear groups. Surface polygons are created from those modeling primitives using a simple table look-up operation. Comparing with previous method such as Marching Cube or PVP algorithm, our method is robust and does not make any crack in resulting surface model. Hardware implementation is expected to be easy because our algorithm is simple(scan-line), efficient and guarantees data locality in computation time.
