Last year, a disastrous accident happened on the sea. Car ferry Se-wol which was on its way from In-cheon to Je-ju sank in the middle of the western sea. 304 passengers were drowned at the sea in the accident. There were no passengers who were waiting on board ship rescued in the accident. This study is to review the pattern of decision making in the middle of saving a life, right after Se-wol was about to sink. The starting point of this study is decision making on the rescue by rescue corps with no expert knowledge at the initial stage. When it comes to saving victims, there was no expert on rescue on the sea. Failure in rescue at Se-wol disaster lets us find a vicious circle of positive feedback loop. Experts with no experience act like well-qualified persons. Unqualified persons(leaders) have no expertise. Those who pretend to be expert occupy the important post in the hierarchy. It means we could not accumulate expertise of know-how in rescue division. That's why a vicious circle of positive feedback is formed in areas of disasters. It is necessary to train experts in Government Organizations to weaken the vicious circle of positive feedback.

This paper proposes how to build an expert profile database in KMS, which provides the information of expertise that each expert possesses in the organization. To manage tacit knowledge in a knowledge management system, recent researches in this field have shown that it is more applicable in many ways to provide expert search mechanisms in KMS to pinpoint experts in the organizations with searched expertise so that users can contact them for help. In this paper, we develop a framework to automate expert classification using a text categorization technique called Vector Space Model, through which an expert database composed of all the compiled profile information is built. This approach minimizes the maintenance cost of manual expert profiling while eliminating the possibility of incorrectness and obsolescence resulted from subjective manual processing. Also, we define the structure of expertise so that we can implement the expert classification framework to build an expert database in KMS. The developed prototype system, "Knowledge Portal for Researchers in Science and Technology," is introduced to show the applicability of the proposed framework.

This paper examines the interdisciplinary practice within design realms including urban planning, architecture, landscape architecture and interior design. It discusses the pedagogical approaches at design schools to foster designers capable of design challenge with interdisciplinary skills. As the complexity of contemporary multicultural society increasingly requires a higher level of expertise in professional service, no individual designer can be expert in all fragmented expertise across the whole design and associated engineering areas. A designer, therefore, should rely on the expertise of other practitioners in areas where he or she doesn't possess proficiency and educational background. From this sense the need of interdisciplinary approaches across diverse range of design and engineering through the collaboration is rising. Historically most of discussion made on interdisciplinary approaches is limited to collaboration between architecture and supporting engineering. This paper focuses on the collaboration with design realms. Three case studies done in an interdisciplinary firm are explored, focusing on design process that is non-linear and complementary. Finally the integrative pedagogical approaches to provide students with more exposure to allied disciplines are navigated with exemplary student work from interdisciplinary design studio.

Consumer innovativeness is a force that leads to innovative behavior of consumer and it is crucial for companies to understand the innovativeness in association with the new innovative product adoption. The purpose of this paper is to examines the influence of Consumer's inherent innovativeness, product involvement, and product expertise on consumers's vicarious and adoptive innovativeness. For this purpose, the model has been set and examined the influence of consumer innovativeness, product involvement and product expertise on vicarious and adoptive innovativeness. The results revealed that 1) consumer innovativeness would not influence vicarious and adoptive innovativeness, 2) vicarious innovativeness had affect on adoptive innovativeness 3) product involvement had a affect on both vicarious and adoptive innovativeness 4) product expertise had a affect on vicarious innovativeness and yet had no affect on adoptive innovativeness.

The purpose of this study was to examine the current states of role model and effects on the expertise development in engineers (i.e., undergraduate students and experts in the field of engineering). Based on the previous studies, role model was categorized into two domain, general role model and value sharing role model. A total of 257 participants (162 undergraduate students, 95 experts) answered survey questions about their role model (the number of their role model, the frequency of meeting with them, and the number of sharing value with them), major confidence, knowledge acquisition, and research performance. The results showed that engineers had 1 or 2 general role models and that the contents of role model were different between the two groups. The value-sharing role model significantly predicted major confidence and research performance in undergraduate students whereas the number of general role model was closely associated with major satisfaction in experts. These results suggest that it is important for engineering major students to have general role model and value-sharing role model in order to enhance expertise development. Establishing infrastructure for having and meeting with role models can facilitate the development of personal expertise in engineers.

The purpose of this study is to analyze The Effect of Teacher Participation-oriented Education Program (TPEP) centered on Multi-Faceted Analysis of Elementary Science Classes on the Class Expertise of novice teacher. First, in order to develop the TPEP, lectures and exploratory science classes were analyzed using imaging and eye-tracking techniques. In this study, the TPEP was developed in five stages: image analysis, eye analysis, teaching language analysis, gesture analysis, and class development. Participants directly analyzed the classes of experienced and novice teachers at each stage. The TPEP developed in this study is different from the existing teacher education program in that it reflected the human performance technology aspects. The participants analyzed actual elementary science classes in a multi-faceted way and developed better classes based on them. The results of this study are as follows. First, at the teacher training institutions and the school sites, pre-service teachers and novice teachers should be provided with various experiences in class analysis and multi-faceted analysis of their own classes. Second, through this study, we were able to identify the limitations of existing class observations and video analysis. Third, the TPEP should be developed to improve the novice teachers' class expertise. Finally, we hope that the results of this study are used as basic data in developing programs to improve teachers' class expertise in teacher training institutions and education policy institutions.

This study aimed to investigate the effects of the virtual reality simulation for malocclusion examination for dental education. A 4-step modeling procedure was applied to develop a tooth model with a realistic level in order to be held and observed in detail. Eighty-six participants used HMDs to examine the developed virtual dental simulation to identify their perception according to expertise levels. The independent variable, expertise group, included three levels: 29 juniors, 29 seniors, and 28 dentists, respectively. The dependent variables, that were task-load and usability, were measured through two cases. Results showed that the junior group perceived a higher level of mental demands and embarrassment than the dentist group. It indicated that the perceived task load varies according to the expertise levels in the simulation task. However, the senior group perceived a higher level of ease of use than the dentist group. This study presented the implications for the development of virtual reality simulation in detail.

The purpose of this study was to investigate whether customers' fashion involvement, brand familiarity, and expertise of negative information moderate the influence of the original brand attitudes on the attitude toward extended brand attitudes in the fashion market. For these purposes, four hypotheses were developed and data was collected from 480 students. Data was analyzed using SPSS methods such as factor analysis, frequency, 1-test, and moderated regression analysis. The results were as follows; first, it was found that the original brand attitudes positively influence the extended brand attitudes. Second, the influence of the original brand attitudes on the extended brand attitudes was stronger when fashion involvement was high rather than low. Third, in the case that perceived similarity between the original and the extended product classes was high, the influence of the original brand attitudes on the extended brand attitudes was stronger when brand familarity was high. Fourth, the influence of original brand attitudes on the extended brand attitudes was stronger when the perceived expertise of negative information source on the extended brand was high. Therefore, the results suggest that extending brands requires the systematic brand management considering customers' variables such as fashion involvement, brand familiarity, negative information etc. Also, it seems that the brand strategy should be based on the segmentation for targeted customers' characteristics.
