시맨틱 데이터는 인간이 의도한 정보를 효과적으로 기계에게 전달하는 정보 양식이다. 그러나 시맨틱 정보를 웹 브라우저를 통해 CGI 코드로 처리하는 방식은 정보 시스템내의 정보구조와 이의 처리 코드가 고착되는 문제점을 안고 있었다. 이를 해결하기 위해 본 논문에서는 시맨틱 정보를 담는 RDF 술어를 기술하는 XML 스키마를 제안한다. 해당 스키마로 기술된 RDF 술어는 HTML 폼으로 자동으로 생성되며, 해당 폼에서 받아들인 데이터를 기반으로 대응되는 RDF 문서를 생성하는데 사용된다. 제안된 스키마를 이용함으로써, 정보 시스템 내에서 RDF 구조의 동적인 변경이 용이하며, 표준화된 방식의 RDF 데이터 입력이 가능해지는 효과를 얻게 된다.

근래에 들어 어류 양식 분야가 활기를 띠면서 어류 종묘생산에 대한 관심도가 높아지고 있다 그럼으로 인하여 먹이생물에 대한 중요성이 높아졌고 이에 대응하는 먹이생물의 연구가 많이 이루어지고 있다. 지금까지 먹이생물로 이용되어온 것은 Chlorella와 Rotifer, Artemia등이며 Chlorella와 Rotifer는 현재까지 배양하는데 별다른 문제가 없어 이용되고 있으나 Artemia는 전세계적으로 생산이 급감하는 추세이며 우리 나라의 경우는 전량수입에 의존하여 국가적 손실이 크므로 이에 대한 대체먹이생물의 개발이 시급한 실정이다(김 등, 1999).

This study examines how full-time housewives manage family resources, make decisions, handle pressures, and negotiate the constraints of everyday life in a society that places unrealistic expectations upon them. We approached housewives with an assumption that they are individuals who think, strategize, and solve problems. We also imagined that they are capable of speaking for themselves and making choices under situational and personal limits. Eleven full-time housewives were interviewed on how they experience their marriage, child (or children), family, and society. Their narratives were then analyzed to sort out the strategies the women employ to maintain their identities. The narratives demonstrate the women's will and agency as they work to resolve the contradictions from their daily life, and reveal individual differences in their midst, despite the fact that they had been often considered homogeneous.

선행 연구개발한 집단감시 디지털 시스템(Group Digital Surveillance System for Fishery Safety and Security, GDSS- F2S)은 대단위 양식장에 침입하는 도적을 방어하기 위하여 레이더 추적정보와 적아식별 정보를 제공하는 시스템이다. 그러나 GDSS-F2S에서 제공하는 두 가지 정보만으로는 도적행위를 입증할 수 있는 법적 증거자료로 미흡하다. 본 논문에서는 이러한 문제점 해결방안의 하나로 CCD 카메라를 이용한 영상획득 장치를 개발하여 GDSS-F2S에 부가한 연구내용을 기술한다. 영상획득 장치 개발에 앞서, 실험지역의 지리적인 특성을 고려한 도적침입 예상경로 분석과 도적행위 시나리오를 기반으로 유효한 대응수단을 검토한 결과, 영상획득 장치가 유효한 대응수단임을 확인하였다. 영상획득 장치는 저가이변서 성능이 우수한 0.0001 룩스의 초저조도 CCD 카메라와 부가장치를 이용하여 개발하였다. 6개월 이상의 장기 현장실험을 통하여 본 연구에서 개발한 시스템을 평가한 결과, 주간은 물론 1 미터 앞도 식별할 수 없는 야간에도 차량의 행동과 번호판 및 사람의 행동과 인상착의 등의 영상정보를 확보할 수 있었다.

This paper tries to explore the overall profile of Korean female labor force over the period of 1960-2000. A particular emphasis is put on portraying major over-time characteristics of female labor force, following five different political regimes--that of Park, J.H.(1960 and 1970s), of Chon D.H. (early and late 1980s), of Roh T.W. (late 1980-early 1990s), of Kim,Y.S. (early 1990-1ate 1990s), and of Kim. D. J. (late 1990-early 2000s), respectively. Discussions have centered around: 1) utilization of young single girls from rural areas during the early industrialization process of 1960-1985; 2) the beginning of married women's entry into labor market and issues of the socalled &M-curve& thesis in Korean experiences since 1990s; 3) the emergence and enlargement of non-regular workers; and 4) the launching of labor related legal measures such as the Equal Employment Act of 1988 and its successive revisions, the Maternity Leave Acts, the On-the-Job Chi1dcare Centers, and the prohibition of sexual harassments on the job setting, and so on. All in all, although it is undeniable that the Korean female labor force has experienced much progress over the period of time in terms of &equality and protection& issues, overall industrial reality we are facing with has not been so prosperous in the sense that most women workers have become the victims of industrial polarization, as time goes by.

The pile driving process may lead to ground heaving, causing additional positive skin friction to act on the piles, compromising their stability. This study proposes a new pile foundation type that can reduce positive skin friction. This was investigated by designing and constructing a pile with a hydraulic cylinder which actively responds to ground deformation. The newly proposed pile design was compared against traditional piles in multiple model tests where ground heaving was simulated. In the tests, base load and total shaft resistance were measured during ground heaving and with expansion of the hydraulic cylinder. As a result of the tests, a very small amount of expansion of the hydraulic cylinder member completely reduced the positive skin friction and increased the base load. Excessive expansion of the hydraulic cylinder, however, generates negative skin friction beyond the zero skin friction state. Therefore, it is necessary to estimate the appropriate level of hydraulic cylinder expansion, taking into account the amount of ground heaving and the allowable displacement of the pile.

For the reduction of flood damage, it is necessary to analyse shelter activities of local residents and to publish information of floodings, In this paper the control factors of individual refuge activities which are major activities to save peoples lives against floodings have been estimated. Decision making factors for mental refuge activity by the questionnaire survey were classified into two categories: internal and external ones. Furthermore, the behaviour patterns of residents for flood risk related to geographical and social factors were derived by the quantification method n. Since spatial layered information using GIS were corrected and estimated to serve citizen's consensus due to flood disaster, it would aid reduction and minimization of flood risk.d risk.

We need measures that can come up with alternative about fishery living zone and enhance local acceptance for responding to the increase in the proportion of renewable energy production and construction of 12GW Offshore wind power according to Korea's Renewable Energy 3020 initiative and Korean-version New Deal. In this study, We suggest that differentiation plans of co-location model in connection with offshore wind power generation suitable for the East Sea. The East Sea is an optimal site for building of a floating offshore wind power generation(FOWPG) field. It is expected that economic effects like energy production, aquatic resource development and tourism industrialization by farming bluefin tuna which is high valued fish and suitable for offshore aquaculture on public waters in FOWPG field. And we can confirm that budget reduction, smart management by sharing operation management technology and increase in fishermen income.

In order to resolve the problem of change in global climate which is worsening as days go by and to preemptively cope with strengthened restriction on carbon emission, the government enacted 'Framework Act on Low Carbon Green Growth' in 2010 and selected green technology and green industry as new national growth engines. For this reason, the necessity to use the un-utilized waste heat across the whole industrial system has become an issue, and studies on and applications of recycling in the agricultural and fishery fields such as cultivation of tropical crops and flatfishes by utilizing the waste heat and thermal effluent generated by large industrial complexes including power plants are being actively carried out. In this study, we looked into the domestic and overseas examples of having utilized waste heat abandoned in the form of power plant thermal effluent, and carried out economic efficiency evaluation of sturgeon aquaculture utilizing thermal effluent of Yeongwol LNG Combined Cycle Power Plant in Gangwon-do. In this analysis, we analyzed the economic efficiency of a model business plan divided into three steps, starting from a small scale in order to minimize the investment risk and financial burden, which is then gradually expanded. The business operation period was assumed to be 10 years (2012~2021), and the NVP (Net Present Value) and economic efficiency (B/C) for the operation period (10 years) were estimated for different loan size by dividing the size of external loan by stage into 80% and 40% based on the basic statistics secured through a site survey. Through the result of analysis, we can see that reducing the size of the external loan is an important factor in securing greater economic efficiency as, while the B/C is 1.79 in the case the external loan is 80% of the total investment, it is presumed to be improved to 1.81 when the loan is 40%. As the findings of this study showed that the economic efficiency of sturgeon aquaculture utilizing thermal effluent of power plant can be secured, it is presumed that regional development project items with high added value can be derived though this, and, in addition, this study will greatly contribute to reinforcement of the capability of local governments to cope with climate change.

With increased complexity of product and market, the phenomenon that a consumer get paradoxical attitude toward marketing object has been increased. And this phenomenon eventually affects the relationship between consumer and product. In this study we tried to find more paradoxical phenomenon and understand consumer behavior confronting these situations when they buy agro-product based on ground theory methodology. According to the results, consumer's expectation and purchase experience can promote quality paradox experience during confronting various marketing activities such as price, product, promotion, place. Also these experience can cause quality paradox related interaction and communication even though there could be differences in their experience according to demographic characteristics, personal preference, and risk perception. Consumer will develop multiple strategies against quality paradox to manage the uncomfortable paradox experiences.
