The emergence of ubiquitous autonomic computing and network environment will change the service architecture information system which will be a new application area in SCM/logistics systems. In this study we surveyed the technical trend map of ubiquitous and its application in SCM/logistics support system design. We described the evolutional model of ubiquitous computing community for SCM/logistics system. It is consisted of three view points; self-growing, autonomic, and context-aware, which will allow the decision makers to be benefited from web and mobile technology and are useful for proactive SCM/logistics support system. Finally, we suggested a cooperative research planning for the development ubiquitous system between the government research center, university, and industry research activities.

Radar is an indispensible equipment in all vessels under way. In Korea there are many fishing net buoys near the coast, which causes an enormous threat to safe navigation because it is very difficult to detect the buoys by radar due to their small radar cross section. In this study RTE(Radar Target Enhancer) was installed on the fishing net buoy and its echo was analysed carefully. The results showed the possibility of wide detection of targets, especially small targets such as fishing net buoys, navigation buoys and etc.

최근 RFID 기술의 급속한 확산은 기존 인식매체의 한계를 극복하고, 기업 및 산업 전반에 새로운 혁신을 가져올 것으로 예상된다, 특히 항만물류산업의 경우 RFID 기술이 적용될 경우 많은 파급효과를 가져올 것으로 예상된다. 우리나라에서는 정부의 각종 시범사업을 통해 RFID 기술을 항만물류산업에 도입하려 하고 있으나 현실적인 개선과제 및 표준화 등에 대한 연구 부족 등으로 많은 어려움을 겪고 있다. 본 연구에서는 기존 문헌 조사와 현업 조사 분석을 통해 단위 업무별 공통 사용 데이터를 도출하여 RFID 국제표준을 준용하는 항만물류산업의 RFID 데이터 표준안을 제시하고자 한다. 향후 본 연구는 현재 진행되고 있는 국가표준안 수립에 적극 활용되어 세계 RFID 시장에서 우리나라의 위상을 높이고 기타 응용분야 국제 표준 규격 제정 시 우리나라의 입지 개선에 큰 역할을 해줄 것으로 기대된다.

The intricacies of web development have orchestrated a paradigm shift in academic libraries. The study explored literature on the status of automation of academic libraries and web development in Nigeria. It was established that the functions of library management software are abysmally under-utilized in academic libraries in Nigeria, thus, progression of automation projects remain a swinging pendulum. The paper, therefore, recommends that librarians should acquire the relevant training and plan strategically for all automation projects aimed at incorporating the intricacies of the web and ICTs into library services to fully utilize the functions of the library management systems in line with web developmental stages, thus, be able to compete globally.

In the past, interest in air pollution was concentrated on greenhouse gases, but in recent years, interest in fine dust has been increasing. The media and environmental organizations continue to emphasize air pollution caused by fine dust. The awareness of fine dust is increasing, and air pollution generated at ports is analyzed to be serious as a domestic factor excluding foreign inflows. Recognizing this, in order to reduce air pollution generated at ports, special laws on improving air quality, such as port areas, have been enacted in Korea, and attempts are being made to curb air pollution caused by ports. In this law, it is a policy that regulates air pollutants generated not only by ships but also throughout ports such as vehicles and unloading machines, and representative are ECA, VSR, and AMP. This study attempted to analyze the effects of these eco-friendly policies at Incheon Port. First of all, a study was conducted to calculate emissions assuming that there was no policy, analyze each policy, and finally calculate and compare actual emissions reflecting all policies. The methodology presented by the European Environmental Administration and the U.S. Environmental Protection Agency was used, and pollutants to be analyzed were analyzed for sulfur oxides (SO_X), carbon monoxide (CO), nitrogen oxides (NO_X), total floating substances (TSP), fine dust and ultrafine dust (PM₁₀, PM_2.5) and ammonia (NH₃). As a result of the analysis, it was analyzed that the actual emission reflecting all policies was about 4,097 tons/year, which had an emission reduction effect of about 760 tons/year compared to about 4,857 tons/year when the policy was not reflected. When the effects of each policy were analyzed individually, it was found that ECA 4,111 tons/year, VSR 4,854 tons/year, and AMP 4,843 tons of air pollutant emissions occurred The results of this study can be used as basic data and evidence for policy establishment related to the atmospheric environment at Incheon Port.

Soil, ground water and sea bed are exposed to continuous accumulation of polluted materials causing serious environmental damage. It has been reported that such pollution causes a massive mortality of fish stock in rivers by the resuspension of toxic chemicals during strong wind conditions. Therefore, it becomes apparent that there is an immediate demand for the restoration treatment of polluted river bed (or sea bed) sediment layers. Pollution levels of major rivers and ports such as Pal-dang, Kyung-an rivers, Ma-san port are becoming public concern and are posing a serious environmental threat. In particular, the pollution of Shi-hwa river has become a nation wide issue for last few years. In spite of such public concern, the pollution level of such rivers or port are getting worse everyday. In this study, an environmentally sound engineering package is introduced which helps to restore the polluted river bed or sea bed sediments. This engineering package is consisted of a suction facility followed by a series of mechanical, chemical as well as biological treatment units. The suction facility is designed to minimize the secondary pollution due to the resuspension of toxic materials during suction. The sea bed cleaning engineering package is designed to be installed on the top of a floating barge. Such combination of environmental plant and shipbuilding technology provides a cost-effective solution, minimizing the cost involved in the transportation between suction and treatment facilities.

국내 항만공사는 항만공사법이 2003년 제정되고 부산항만공사가 2004년 설립된 이후 인천항만공사, 울산항만공사, 여수광양항만공사가 설립되어 운영되고 있다. 그러나 항만공사의 운영이 비효율적인 방향으로 흘러감에 따라 정부를 중심으로 공기업 통 폐합 등의 조직 개편 움직임의 목소리가 나오고 있다. 정부에서 구상하는 개편 방안 중 항만관리에 대해 통합적 운영이 적절한지, 분권적 운영이 바람직한지에 대해 보다 심층적인 논의가 필요하다. 본 연구는 항만공사 운영방식 개혁에 대한 논의에 대비하여 이러한 통합적인 접근방식과 분권적인 접근방식에 대한 비교분석을 하는 것을 그 목적으로 한다. 이를 위해 항만공사제도의 도입배경과 현황, 조직의 통합운영과 분산운영에 대한 이론적 배경, 국내 공기업 통합 사례 및 해외항만 운영 사례, 항만공사 운영 방식의 대안별 비교를 실시하였다. 이를 통해 다음과 같은 결론을 얻을 수 있었다. 첫째, 항만공사제도는 기존의 항만관리제도 개선을 위한 노력이라는 역사적 맥락을 기반으로 하여 기존 관리제도의 문제점을 개선하기 위한 대안으로 도입된 제도이며, 이러한 제도적 목적을 기반으로 항만공사 운영개선방안 논의가 되어야 한다는 것이다. 둘째, 공공기관 운영에 있어 내재되어 있는 문제점을 개선하기 위해 기관통합, 기능 조정, 부분통합 등 다양한 방식으로 개선이 가능하며 반드시 하나의 방법으로 이루어 질 수는 없다는 것이다. 셋째, 해외 주요 항만의 경우 개별 항만에 항만공사를 운영하는 개별적 운영방식을 택하고 있으며 대만이 유일하게 통합 운영하는 방식으로 개편하였으나 그 통합으로 인해 기대하는 효과가 실현되고 있지 않아 통합운영 방식의 근거가 되기는 어렵다. 넷째, 항만의 운영 자료를 분석한 결과 항만별로 처리하는 화물과 선대의 특성이 차이가 나고 운영방식과 대상이 되는 시장이 다름을 알 수 있었다. 이러한 항만별 운영과 고객의 차이를 감안하면 개별적 운영방식이 바람직하다고 판단된다. 결과적으로 통합 운영방식의 운영 효율성 개선 효과가 있을 수 있음에도 불구하고 항만공사제도의 목적과 취지를 감안할 때 현행 개별운영 방식을 유지하는 것이 바람직하다는 결론을 제시한다.
