국내 해양레저산업 중 세일요트산업은 현재 초기시장을 형성하고 있으나, 현재 정부의 해양레저 활성화 정책과 해양레저 인구 또한 관련 협회, 클럽 등의 중심으로 급속한 증가세를 이루고 있다. 이에 요트수요 증대에 따라 요트 관련 부품 소재의 경우에도 향후 그 수요가 대폭 증가할 것으로 예상되어지고 있으며, 그 중 요트용 돛(Sail)의 경우에는 전량 해외 수입에 의존하고 있어 제품개발을 통해 국산화함으로써 해외 제품의 수입대체가 요구되고 있다. 본 연구는 해외의 산업용 폴리에스터 원사로 제조된 요트세일 제품의 특성 및 성능 분석 결과와 국산 고강력 폴리에스터 소재로 제조된 요트 세일 개발 제품의 물성 및 성능을 비교 분석하고자 한다. 세일 제품 개발을 위해 해외 요트용 세일 제품을 분석한 결과, 소재는 고상중합형태의 폴리에스터 산업용 원사를 사용하여 직물자체의 고강도 및 저신도 특성발현을 위한 고밀도 제직을 실시한 것으로 분석 되었으며, 가공에서는 해양에서 사용하는 세일 직물의 특성 상 일광 및 자외선에 대한 내구성을 높이고, 황변을 방지할 수 있도록 하기 위해 직물표면에 멜라민계 수지를 이용한 함침방식의 특수코팅을 실시한 것으로 분석되었다. 이러한 해외 요트용 세일 제품의 분석결과를 바탕으로 국산 고강력 폴리에스터 고밀도 직물에 자외선 및 일광에 대한 내구성이 우수한 무황변 타입의 폴리에스터계 수지를 사용하여 단면 코팅으로 양면코팅 가공효과를 부여하는 나이프 방식의 특수코팅, 에이징 처리를 통해 세일을 제조하였다. 본 연구에서는 제조된 세일 직물 제품에 대해, 물리적 특성을 분석하기 위해 인장 강신도, 무게, 두께 및 주사전자현미경 관찰 등의 테스트를 실시하였으며, 세일 성능 분석을 위해 공기투과도, 일광견뢰도 자외선 조사 후 강도변화, 황변 Test 등의 테스트를 실시하여, 해외 선진 제품과 개발제품의 물성 및 성능에 대해 고찰하였다.

Korea, old buildings do not currently have earth-resistant facilities, and disaster prevention facilities have some limitation in responding properly to damage arising from natural disaster as they do not reflect recently occurring climatic changes. Accordingly, it is necessary to select vulnerable districts by taking into consideration the possibility of disaster occurrence and the current situation of infrastructures for disaster prevention in order to responding efficiently to future unexpected disasters. For this purpose, national government has recently formed the DB linkage council for disaster prevention under the participation of related agencies and constructed integrated database. But local governments have not properly provided it with basic data necessary to construct database, resulting in the delay of the project. Therefore, it is thought that national government needs to provide them with manpower and financial support.

본 연구는 현재 도입예정에 있는 차세대 통신 및 방송서비스의 확산가능성에 대하여 잠재적 사용자1,000명을 대상으로 조사한 최근 조사자료를 중심으로 실증분석하였다. 잠재적 사용자의 선택 및 반응함수추정방법은 분석의 객관성과 효율성을 유지하기 위하여 모수적 추정과 반모수적 추정방법을 동시에 사용하여 분석하였다. 본 분석결과를 요약하면 다음과 같다. 먼저, 차세대 통신 및 방송서비스사용자들의 해당 서비스선택반응함수를 분석한 결과 서비스확산은 상당히 느리게 이루어 질 수 있다는 결과를 보여 주었다. 이러한 분석결과는 기존 초고속 및 이동통신서비스 확산에서와 같이 형태의 빠른 확산속도를 보일 것이라는 낙관적 전망견해에 상당한 문제점이 있음을 보여 준다. 둘째, 본 연구의 차세대통신 및 방송서비스확산의 부정적인 분석결과에도 불구하고, 차세대 통신서비스의 성공적 확산에 중요한 요인으로는 서비스제공요금을 낮추고, 젊은 사용자층에게 새로운 서비스의 유용성을 인식시킴으로써 최종서비스선택까지 유도케 할 수 있는 유인 메커니즘 도입전략 개발이 사업성공의 필요조건이 될 수있음을 보여 주었다. 마지막으로 우리나라 통신 및 방송산업환경은 상용화를 준비하는 사업자들이 차세대 통신 및 방송서비스의 성공적 도입을 위하여 시장구조분석 및 시장욕구의 질적 방향분석뿐만 아니라, 그 영향 정도를 수치화하고 계량화하는 시장분석자료를 바탕으로 시장도입 및 전개전략을 개발하는 과정이 절대적으로 필요한 단계가 되었음을 보여 준다. 본 연구결과의 시사점으로 차세대 통신 및 방송서비스의 산업고도화에 대한 면밀한 사전계량시장분석으로 시장전략형성 전환적사고가 해당 서비스제공사업자뿐만 아니라 서비스정책을 수행하는 정부당국자에게도 필요과정요소가 되고 있음을 보여 준다.

The primary purposes of this study are to find a proper model for government's selections of Mainbiz and present what are the better weights of the current indexes. We prepared three sets of models：first one using original 10 variables; second one using 9principally composed variables; third one using 7 principally composed variables. Among 3 models, the last one had higher explanation power than the other two models. Therefore, if index weights are adjusted according to the third newly developed model, the credibility in evaluating and selecting Mainbiz will be improved. When transforming the index weights and running the analysis, 5 variables(organization process, marketing management, management process, production-facility states, the level of forecasting) have more direct influences than other 4 variables(innovation strategies, knowledge management, achieving level, operational level) on selecting Main-biz.

In order to promote software industry, it is essential to train and utilize specialized software human resources in the industry. It is required to establish an appropriate qualification system for the industry in order to train and utilize the qualified human resources. The current national qualification system in the IT area cannot cope with the development of software industry and does not provide various qualifications required to the software workers. We analyze the problems of the current national qualification system for the software industry and propose a framework for improving the qualification system. Based on the review of the software skill standard and a range of technology levels, we suggest a new integrated qualification system that provides a variety of qualifications for various software skills at various levels. Also we propose policy alternatives for institutionalizing the new qualification system.

The Korea built successfully e-Korea based on the best of internet infrastructure which was constructed in the world. Continually, Korea is constructing u-City for twenty-first century to enhance the quality of life and to grow up IT industrial. But there is no standard model for u-City because three main builders, central government, local autonomous entities, and communication carriers have respectively their objects, targets and domains. If u-City would be constructed by the common infrastructure for ubiquitous communication, it will be possible to provide any ubiquitous services and compatibility. And the communication infrastructure has to be reflected on the first stage of city planning to reduce high cost for u-City construction. This paper mentions firstly the ranges of communication infrastructure and shows how to construct it each range.

Damage caused by private information breach causes serious problems and huge social losses. In order to make a better policy that prevents society from suffering from the damage, we have to know about the actual size of damage. So it is needed to develop a quantitative model of private information breach that helps catching the more accurate size of damage. In our study, we suggest a method which calculate not only the costs of damage from firms' perspective but also those from individual and social perspectives. In this process, we refer to methods adopted by JNSA(Japan Network Security Association) and Ponemon Research Institue and modify it with considering our current situation. Also we try to make a new model by using new methods(web traffic analysis, survey, indirect comparison, etc.) and verify it with theories and methods from econometrics, cost accounting and theory of producer.
