This study identifies the concept of a digital convergence paradigm, which deals with the relationship among convergence and consumer participation, digital contents services, and the culture of consumption (web 2.0). This research was conducted using a quantitative method involving focus group interviews (FGI) and literature reviews. This research examines the relationship between convergence and consumer participation and the adoption of a concept of "convergence culture", which is categorized as "collective intelligence" and "intellectual community participation". The role of the consumer has changed from one of a "consuming consumer" to that of a "collaborating consumer" and finally to the concept of a consumers as the originator of a new consumption culture. In the study, the consumption culture of web participants indicated the characteristics of funology, self-expression, life-catching, quick-tempered, immersion(arousal), sharing culture, multitasking, and cyber justice. The recognition level of networking on the "digital convergence" of the consumer was identified as that of the combination of IT(information technology); product and multi-services or alliance of industry groups(telecom, broadband, IPTV service); or the use of one source with multiple devices.

Although synthetic aperture focusing techniques can improve the spatial resolution of ultrasound imaging, they have not been employed in a commercial product because they require a real-time N-channel beamformer with a tremendously increased hardware complexity for simultaneous beamforming along M multiple lines. In this paper, a hardware-efficient beamformer architecture for synthetic aperture focusing is presented. In contrast to the straightforward design using NM delay calculators, the proposed method utilizes only M delay calculators by sharing the same values among the focusing delays which should be calculated at the same time between the N channels for all imaging points along the M scan lines. In general, synthetic aperture beamforming requires M 2-port memories. In the proposed beamformer, the input data for each channel is first upsampled with a 4-fold interpolator and each polyphase component of the interpolator output is stored into a 2-port memory separately, requiring 4M 2-port memories for each channel. By properly limiting the area formed with the synthetic aperture focusing, the input memory buffer can be implemented with only 4 2-port memories and one short multi-port memory.

Social media which support to share information and communicate between online users have recently won great popularity. Of the various social services blogs have played an active role as a community in sharing delivering and exchanging information among individual users who have share similar opinions hobbies and preferences. Based on this cultural phenomenon some companies often take advantage of blogs as a marketing tool to strengthen their public relations or deliver particular information to their costumer. This study is designed to classify fashion-related blogs and define the characteristics of each type expecting significant influences on future studies on this topic. We selected 50 fashion-related blogs as subjects including 25 Korean blogs and the same number of international blogs, defined their characteristics and classified them into four different types. As the result we found that there are apparent differences between the four types of blogs: "Individual taste" blogs which noticeably reflect bloggers' own preference "Trend leader" blogs in which the bloggers intend to be trend leaders beyond expressing their preference "Fashion media" blogs which plays a significant role as a magazine by providing various information concerning fashion for costumers and "Sales promotion" blogs which are used as promotional materials to attract customers by providing product reviews or advertisements.

Nowadays, one of the major technical issues in manufacturing is to create an environment to promote collaboration among diverse engineering activities. Collaborative engineering is an innovative approach integrating widely distributed engineering activities through promoting information sharing and actual collaboration. It requires close interactions among developers, suppliers and customers, and consideration of entire product life cycle from concept to disposal. A carefully-designed operating system is crucial for successful collaboration of many different activities in a Networked Virtual Manufacturing System(NVMS). High extensibility, flexibility and efficiency ale the key characteristics requested of an operating system to handle the complexity of the NVMSs. In this paper, we propose a model of the operating system for collaborative engineering using concurrent quasi-procedural method(QPM). QPM is a goal-driven data management technique for distributed and parallel computing environments. It is to be applied to the evaluation of activities to be executed, validities of input data, execution path of activities for a needed output, and expected to greatly improve the productivity of operations by preventing redundant evaluations. Collaboration among many different engineering activities in NVMSs is to be performed by the network of agents that encapsulate the capabilities of both users and their tools.

The efficient and well organized database is essential for the management of information in every industrial field. In this study, a practical and effective database which can handle 3-D information of steel bridges is built on the basis of a STEP-based data model. The data model of steel bridge information is classified into geometric and non-geometric part and the design information is represented by linking geometric information and life cycle supported non-geometric information. Especially, the shape information is represented by boundary representation method, which is one of the representative methods of solid model information. In this study, ISO/STEP(STandard for the Exchange of product model data) AP203(configuration controlled design) EXPRESS schema is used to represent the shape information of steel bridge. The syntax of EXPRESS schema of developed data model is verified by NIST Expresso - is a tool for parsing and compiling EXPRESS schema. Also, this study verifies the conformance of the data model by applying to the real data of Hannam bridge. Therefore, the constructed database using STEP-based data model of steel bridges can be used effectively in the concurrent engineering point of view with transferring and sharing steel bridge information.

TOEM strategy is widely used in Japan and Korea because of the diverse advantages such as cost sharing, technology transfer, equipment lease and base technology acquisition between parent company and OEM supplier. There are, however, some disadvantages that (1)OEM suppliers are likely to be reactive to environmental changes and (2) may have difficulty in building competitive position and long-term growth. When the parent company relocates its plant to foreign countries to achieve lower labor cost or to enhance value added this change will affect directly the OEM supplier's outcome. The parent company's divestiture from existing businesses will also affect the OEM supplier. For the OEM supplier to survive in face of these strategic changes it must enter the new countries with the parent company. Alternatively, the OEM supplier must actively diversify its technologies based on its core capabilities of existing product and process technologies and seek new business arenas. The strategy of aligning its businesses with the parent company's new business strategy allows the OEM supplier to share the new market while it requires the OEM supplier to develop core capabilities. In Korea many small and medium sized OEM suppliers are dependent on a few large companies. For the industry structure in Korea where industry concentration is extremely high OEM suppliers should move away from the past strategy, where they are dependent on the parent company's low profitability businesses. They should actively enter new businesses for which parent companies enter to achieve long-term growth.

부산항은 컨테이너터미널 운영사별로 마케팅 전략 수립 및 마케팅 활동이 개별적으로 이루어질 뿐 항만 관련 유관기관(부산시, 부산지방해양수산청, 한국컨테이너부두공단, 부산본부세관)의 조화된 항만 마케팅 전략 및 역할이 수립되지 않은 상태이다. 따라서 본 연구에서는 부산항 활성화를 위한 각 주체별 활동 현황을 조사하고, 항만 이용자인 선사 및 포워더를 대상으로 마케팅 믹스(Mix, 4P: Product, Place, Price, Promotion)에 대한 설문조사를 토대로 부산항 마케팅 분석을 실시한다 이를 바탕으로 부산항이 동북아 중심항만으로 성장하는데 필요로 하는 부산항 관련 각 주체별 마케팅 관계 그리고 역할을 제시한다. IPA(Importance-Performance Analysis) 분석 결과를 살펴보면 전체 고객을 대상으로 평가했을 때 가격 믹스와 촉진믹스는 가장 중요도가 높은 것으로 분석되었으며 특히, 촉진믹스는 중요도는 매우 높으나 만족도가 낮은 것으로 분석되었다. 그러므로 마케팅 전략 수립 시 촉진 부문에도 높은 비중을 두어 선사들에게 공격적인 마케팅 활동이 요구된다고 할 수 있다. 부산항 관련 각 주체별 마케팅 역할에서 부산광역시는 부산지방해양수산청과 함께 촉진믹스에 중점을 두어야하고, 부산지방해양수산청은 촉진믹스 외에 가격믹스에서 항만 요율의 적절성과 경로믹스인 철도 수송 망의 확보가 시급한 것으로 나타났다. 한국컨테이너부두공단은 촉진믹스 외에 가격믹스에서 항만시설 사용료의 체계적인 개편이 요구되고, 터미널 운영사는 제품믹스 서비스인 공컨테이너의 효율적인 재고관리 업무서비스와 가격믹스에서 하역요율의 탄력적인 제공이 필요하다.

Crucial aspects to successfully realizing the re-emergence of a contemporary and sustainable supercomputing community in South Korea will involve the devoted efforts and support from key government and R&D organizations. We suggest various supplementation plans regarding the roles of support for the statutory plan. This includes the committee and the plans which are often missing necessary support systems that help competent ministries to plan properly according to the missions of the research center. This dissertation suggests that adjustment in the HPC trends will depend upon exposing and correcting problems in the law as well as overall improvement of the law. Also, the total development of a super computing market is necessary. The results of these guidelines will create a spread of demand for supercomputing for national IT resource sharing, and will foster the development of supercomputer specialists worldwide. Other major end results include significant increases in research productivity and increased rates of product development.
