The research is centered towards analyzing the differentiation of the characteristics and organization of programming strategy and channel positioning by selecting Korean International Public Relations Broadcasting Stations Arirang TV and KBS World. According to the results, Arirang TV positions Korean culture content-implied educational programs as their strategy while KBS World places the main programs of KBS1, 2TV with many entertainment programs such as dramas and entertainment shows. Arirang TV's programming strategy is well-fulfilling the purpose of promoting Korea's culture contents by organizing their programming with documentaries, tourist information, and daily living information. On the other hand, KBS World works as the agent of the spread of the Korean Wave by filling their program with dramas and K-pop programs such as . Due to the difference in programming strategy of these two broadcasting stations, Arirang TV has positioned itself as a diplomatic channel to spread Korean culture and KBS World a channel representing the Korean Wave. However, there are problems of inefficiency due to recurrent investments because of the fact that both broadcasting stations' programming strategy is to promote Korean culture and spread the Korean Wave by aiming similar targets such as foreigners or overseas Koreans.

This study is to analyze the effect of product involvement on consumer purchase process. From review on previous involvement literatures, enduring product involvement can be defined as "a person's arousal and motivational state activated by product on the basis of his basic value, objective and ego-relevance." To evaluate the effect of involvement on product purchase process, 11 hyphotheses concerning behavioral aspects which is expected to comprise consumer purchase process and to be influenced by degree of involvement were constructed: prepurchase information search, alternative brand comparision, utilization of product attribute, brand differentiation, brand commitment, product knowledge, influence of reference group, dependence on price, price awareness, cognitive dissonance and purchase optimization. Hyphotheses are tested with data from 388 housewives through 20 item involvement scale developed with multi-dimensional perspective on involvement. The scale successfully provides rank order of 8 selected products expected to cover the spectrum of product involvement: formal clothes, coffee, washing machine, shampoo, perfume, detergent, soft drink, pain-reliever as the order of product involvement. Major findings of this study are as follow. First of all, incresed differences were found in hihg involvement product like formal clothes with respect to the degree of prepurchase information search, alternative brand comparision, utilization of product attribute, influence of reference group in any method of analysis. Secondly, invlovement should be interpreted as a consumer characteristic rather than a product one. This means that consumers involve themselves with products, instead products themselves do not have any involvement.

In EPCglobal Class-1 Gen-2 RFID system, a slot-count selection algorithm has been proposed to determine the slot-count size depending on the status of reply slot. In the slot-count selection algorithm of Gen-2, the slot-count value is increased or decreased by the weight C, which is identical and independent of the slot status. It has an advantage that the algorithm is simple, but it is difficult to maintain an optimal slot-count size. Therefore, in this paper, we propose an adaptive slot-count selection algorithm, which applies the parameter C differently based on the result of tag replies. Through simulations, it is demonstrated that the collision rate for the proposed scheme is about 42% and 65% lower than the schemes proposed by Wang and Gen-2. Therefore, the adaptive slot-count selection algorithm achieves faster tag identification time compared with the existing algorithms due to the low collision rate.

For the purpose of the basic educated-establishment on the diagnostic methods of "facial color and shape which reflect human's spiritual essence and personality", we study on the diagnostic value and application of the human face. The study's domain is divided the form and color of human face. And the form and color of human face is respectively observed the diagnostic value and contents. The form of human face reflect plenty the information of the mankind, and the observation of the face is applied to the "Physiognomie" refering to the external features of humans. Therefore the diagnosis on the form of human face is the primary factor in the grouping of five-element human, the discrimination of the Sasang constitution, and the classification of Hyunsang type. The color of human face reflect the physical information of internal organs and the pathological change of disease, therefore we examine the region, character and grade of disease by the inspection of complexion including the changes of color and luster of the facial skin. The inspection on the color is also the primary factor in the grouping of five-element human, the classification of Hyunsang and the differentiation of syndromes. The value of the inspection of complexion including the changes of color and form of the face is widely known. In the future, we think, we need to study more about the theory of the diagnostic value and application of the human face.

본 논문에서는 팀 단위 온라인 액션 게임과의 차별화를 위해 다운 시스템을 적용한 액션게임을 개발하였다. 다운 시스템은 캐릭터가 일정량 이상의 공격을 받을 경우 넘어지며 일시적인 무적 상태가 되는 시스템이다. 캐릭터의 공격과 스킬은 각각 다른 다운 포인트가 매겨져 있으며, 공격자 캐릭터가 수비자 캐릭터에게 공격이나 스킬을 적중할 시 다운 포인트가 쌓이게 된다. 다운 포인트가 한계치를 초과하면 수비자는 다운 상태가 된다. 다운 상태가 된 캐릭터는 넘어지며 일정 시간 무적 상태가 된다. 다운 포인트가 한계치를 초과하기 이전까지의 공격은 다 유효하기에 공격자는 다운 포인트가 초과되기까지의 범위 내에서 최대한 효율적으로 공격을 해야 하며, 수비자는 다수의 적에게 순간적으로 집중 공격을 받아도 일정량 이상의 피해에 노출되지 않기에 반격의 기회를 얻을 수 있다. 단순히 먼저 공격하기에 유리하거나 머릿수가 앞선다고 하여 유리한 것이 아니기 때문에, 다운 시스템을 얼마나 효율적으로 사용하느냐의 여부에 따라 플레이어의 숙련도가 결정된다. 계산적인 공격과 수비를 해야 하기 때문에 단순하게 이루어지는 기존의 팀 단위 온라인 액션 게임과의 차별화를 살펴보았다.

In this paper, a conceptual framework describing the dynamics of click and mortar businesses is provided. It directs our attention to the many potential sources of synergy that are available to firms that choose to integrate e-commerce with their existing traditional forms of business. It further emphasizes the many actions that firms can take to minimize channel conflicts and help achieve the benefits of synergy. Finally, it describes four categories of synergy-related benefits from the integration of e-commerce with traditional businesses, including potential cost saving, gains due to enhanced differentiation, improved trust, and potential extensions into new markets. The utility of the framework was demonstrated using the case of an electronics retailer that has chosen to tightly integrate its large chain of retail stores with its Web-based electronic store. The framework was also used to develop a series of propositions that can guide future empirical research. The discussion points to the need to develop new types of metrics to better judge the contributions of e-commerce channels, and provides some guidance for future empirical research that can test whether, and under what conditions, integrated click and mortar business models work well. Thus, the purpose of this study is to present the combining physical and virtual presence in e-commerce.

This study presents a contents model designed for business records that require long-term preservation. The contents model is based on the PREMIS(Preservation Metadata: Implementation Strategies) data model and the ISAD(G)(General International Standard Archival Description). The study selected the record collection of "the records of the overseas petroleum business and oil field development of A company located in B country." This collection requires permanent preservations by the nation and even beyond. It was attempted to establish the concepts of intellectual objects in the PREMIS data model to apply the PREMIS data model to the business records specifically. In other words, the study established the principles for differentiation of the classes in the record contents and the hierarchy structure, and the hierarchy model was developed for business records contents to derive the business records model based on those principles.

Software Product Line Engineering is a collection of techniques that analyze the commonalities and variabilities of the products within a product family and produce products using such information. In Software Product Line Engineering, construction of the correct core assets is very important. To accomplish this, the commonalities and variabilities must first be definitively identified, both to provide traceability between the core assets, and to guarantee the reliability of the products. This paper suggests software product line development and test processes based on CVL for the differentiation of commonalities and variabilities. The proposed approach enables correct building of the core assets through procedures to keep traceability and guarantee the reliability of the products.

The IETF Differentiated Services (Diffserv) WG focused on Providing service differentiation on the Internet. One problem of the Diffserv Assured Services (AS) architecture is that it cannot guarantee fairness and throughput assurance. In this paper, we propose two schemes for guaranteeing fairness among the various target rates in the AS architecture. One is a variant of RED with IN and OUT (RIO), called the improved RIO (IRIO). The other is a variant of Time Sliding Window (TSW), called the improved TSW (ITSW). To validate the Proposed schemes, their behaviors are then examined under various simulation environments. The simulation results showed that IRIO and ITSW improved fairness and the throughput assurance in the AS architecture.
