Patent application as achievements from R&D institutions in public sector have quantitatively increased by expanding R&D investment for enhancing competitiveness but there have been few tangible outputs from the investment. From this reason, TLO(Technology Transfer&Licensing Organization) and its operation becomes more important to implement technology transfer and commercialization and to bring success in the related business. To get work done more efficiently and to improve utilizing products of the R&D in the TLO, this research is to draw domains and activities of TLO and establish its task systems by prioritizing activities. From literature reviews and expert interviews, we generated 6 work domains and 21 task items. Applying AHP analysis, we discriminated the relative importance from task items and analyzed its priority. The finding of this research can provide implications for TLO to increase work efficiency and improve its performance.

As browsing and sharing multimedia contents through various social network services have become very common these days. there has been a rising demand for effectively provide appropriate multimedia contents to users depending on their interest and characteristics. Especially, considering the enormous volume of multimedia contents created daily, user satisfaction heavily depends on effective selection of appropriate multimedia contents. For instance, if the acquisition of contents is based on friends or related people, then it is usually considered to be more trustworthy. Facebook page is one of the social spaces where people can obtain various information of interest. Still, users have difficulty in finding proper information because Facebook generates tremendous amount of data daily. In this paper, we proposed a scheme to extract and select Facebook page contents effectively. In our proposed scheme, users are grouped based on mutual intimacy and Facebook pages of interest are selected based on the ranking of importance. We show the performance of our scheme through experiments.

The purpose of this study was to derive policy priorities for fostering the biopharmaceutical industry. In this study, the urgency and importance of the policy to foster the biopharmaceutical industry in Gyeonggi-do was investigated, and the priorities of the policy in the biopharmaceutical industry were analyzed through IPA analysis. As a result of the study, the top priority support tasks for the biopharmaceutical industry promotion policy were 'R&D support', 'Expert training', and 'commercialization support'. As a result of deriving policy priorities for each biopharmaceutical sector, 'R&D support' and 'Expert training' were found to be high in common, and differences in policy priorities for each industry such as cell therapy products and advanced bio-convergence products were confirmed. Also, as for the policy demand, R&D funding support, clinical trial support, and commercialization funding support were found to be high. Based on these results, the government's policy to foster the biopharmaceutical industry was supported with a focus on 'R&D support' and 'Expert training', and policy implications were drawn that customized support is needed in consideration of the characteristics of each industry field.

비디오 스트림과 오디오 스트림 그리고 제어신호등의 서로 다른 종류의 digital data 들을 저장 또는 전송하기 위해서는 하나의 스트림으ㅗ 통합하기 위해 다중화 과정을 거쳐야 한다. 이러한 다중화 과정에서 가장 중요한 문제점은 하나로 묶여진 일련의 스트림을 원래의 순차대로 복원해주는 동기화 문제이고, DVD-Video에서는 MPEG2 system를 이용한 동기방식을 사용한다. 본 논문은 DVD 규격에 맞추어 Microsoft의 Visual C++5.0을 이용하여 software로 VOB를 구현하였다. 입력 스트림은 MPEG2로 압축된 비디오스트림과 최대 8개의 5.1채널 AC3 오디오스트림이고 각 스트림은 frame단위로 구성이 된다. 이 frame들을 단위로 time stamp가 부여되며 time stamp의 비교에 의해 우선 순위를 부여하여 encoding을 하게된다. 그리고 같은 time stamp를 가졌을 경우 발생하는 encoding 순서의 문제는 스트림별로 미리 우선 순위를정함으로써 해결했다.

본 연구의 목적은 주부의 시간성향에 따라 시간관리행동에 차이가 있는지를 파악함으로써 시간성향의 중요성을 밝히고, 주부의 생활경영과정에서 시간사요의 효율성을 창조하는 능력으로서의 인적자원계발을 위한 하나의 자료가 되고자 하는데 있다. 본 연구의 결과는 다음과 같다. 첫째, 주부의 시간성향은 단선적 시간성향이기보다는 복합적 시간성향인 것으로 나타났다. 둘째, 주부의 사회인구학적 특성에 따라 시간성향의 차이를 보면 변인은 거주지와 취업여부였다. 세째, 주부의 시간성향에 따른 시간관리행동은 사회하를 제외한 모든관리행동 즉 계획/우선순위(p<.001), 표준설정/단순화(p<.05), 목표설정(p<.001), 심리적 긴장감해소(p<.001), 분담화(p<.05), 기계화(p<.05)에서 차이를 보이고 있다. 유의미한 차이를 보인 모든 관리행동에서 복합적 시간성향의 주부가 관리행동을 더 잘하였고 특히 계획/우선순위와 목 표설정 관리행동에서 월등히 잘하는 것으로 나타났다.

This paper presents new multimedia transmission and synchronization scheme for parallel server in wireless environment. The proposed scheme is developed for the parallel sewer that stores MPEG-4 data according to VOP (video object plane) types, i.e., I-, p-, and B-VOP. The goal of our research is to develop the enhanced multimedia transmission scheme that copes with load unbalancing, congestion, and jitter. Thus, we consider three issues; the data striping, the priority queuing, and the multimedia synchronization. First, we develop a parallel server architecture in which each server separately stores video data that is striped by the MPEG-4 VOP types.

The semantic web environment promise semantic search of heterogeneous data from distributed web page. Semantic search would resuit in an overwhelming number of results for users is increased, therefore elevating the need for appropriate personalized ranking schemes. Culture Finder helps semantic web agents obtain personalized culture information. It extracts meta data for each web page(culture news, culture performance, culture exhibition), perform semantic search and compute result ranking point to base user profile. In order to work efficient, Culture Finder uses five major technique: Machine learning technique for generating user profile from user search behavior and meta data repository, an efficient semantic search system for semantic web agent, query analysis for representing query and query result, personalized ranking method to provide suitable search result to user, upper ontology for generating meta data. In this paper, we also present the structure used in the Culture Finder to support personalized search service.

Due to the ossification of the Internet, it is difficult to accommodate variety services. One of the efficient solution to this problem is network virtualization. It allows multiple parallel virtual networks to run on the shared physical infrastructure. It needs new resource allocation mechanism to share efficient physical resources. In this paper, we present efficient bandwidth allocation algorithm for virtual network request with high service priority. Our proposed algorithm can withdraw allocated bandwidth from low-level priority virtual network and maintain low-level virtual network service. We evaluated the performance of our proposed algorithm using simulation and found the improvement of approximately 8% acceptance rate.

The procedure of present military facility remodeling has many problems at the stage of evaluating the priorities in various remodeling projects which have been caused from lots of corps. These problems have usually happened not only because of the shortage of the cooperation system in the related divisions but also because of the nonexistence of the effective process and method for evaluating the priorities. I've reviewed the study of remodeling and military facility business and applied the AHP(Analytic Hierarchy Process) method which is effective to evaluate the priorities in various groups' decision.

KModSim은 수자원배분에 관련된 물리적, 수문학적, 제도적, 그리고 행정적인 요구들을 동시에 만족하도록 디자인된 범용 우선순위 목적 선형최적화 모형으로써 자연유입량과 기득 수리권 혹은 기득 저류권 등과 같은 다양한 형태의 저수권 사이의 조화운영이 가능하다. KModSim 목적함수에 관련된 제약조건의 유연한 설정과 변경이 가능하며, 기존의 최적화 방법과 다르게 유역통합모의에 관련한 모형변수가 모형내에서 자동적으로 생성되도록 프로그램화 되어있다. 본 연구에서는 유역내 수자원의 효율적인 운영을 위하여 우선순위 목적 선형최적화 모형을 위한 Backrouting 방법을 개발하고 금강유역 일단위 KModSim 네트워크에 Backrouting 방법을 적용하여 적용성을 검토하였다. 금강유역에 KModSim을 적용하고 모의한 결과 Backrouting 방법을 사용한 모의결과가 Backrouting 방법을 사용하지 않은 경우에 비해 실측치를 보다 잘 재현하는 것으로 나타났다. 본 연구에서 개발된 Backrouting 방법은 다중목적 우선순위 선형최적화 모형을 이용하여 일단위 모의 시에 발생할 수 있는 과도한 손실을 방지하고자 할 때 적용할 수 있을 것으로 기대된다.
