  • Currently most of leak detection monitoring systems use digital maps with paying royalties, and this increases the cost of system construction and financial burdens on local self-governing bodies that manage such systems. Moreover, they have inefficiencies in repair and maintenance, functional expansion, and compatibility with other systems. Thus, this study developed a waterworks pipe network monitoring system that pursues low cost and high efficiency using general-purpose maps on the Internet such as google maps. As this system uses highly compatible free maps, it costs less in construction and its hardware requirements are lower than existing systems, and consequently, overall monitoring performance is enhanced and the cost of construction goes down sharply. This study also proposed a method for pipeline DB construction, which can be started together with the construction of the monitoring system, in order to improve the field applicability of the system.

  • In developing an optimum steelmaking process, the purity of the product, environmental impact, capability and cost of the process should be considered. Desulfurization of molten iron is conducted during preliminary treatment stage before converter operation. Although fluorite is added as a desulfurizing agent in CaO and $CaCO_3$ based agents, the concentration of fluorine in slag is strictly regulated. In order to develop desulfurizing agent without fluorine, CaO was mixed with Al dross and ladle slag containing alumina. The characteristics and desulfurizing capacity of the CaO based desulfurizing agent thus prepared were tested by varying temperature of Kanvara Reactor. Our results showed that the desulfurizing capacity of the samples prepared in this work was found to be similar to that of the traditional desulfurizing agents with fluorine.

  • In the system integration (SI) industry, improving relationships with outsourcing partners is one of the key challenges faced by SI companies that aim to increase productivity and reduce costs. In the SI industry, over 80% of project development work is performed by these outsourcing partners. Hence, large SI companies focus on fostering high-performing partners through improved cooperation and mutual relations. However, in the SI industry the existing process of managing outsourcing partners is unable to advance to the level of long-term partnerships due to inadequate information sharing and communication in the process of selecting and assessing a potential and existing partner. Based on the theory of partnership, this study identifies the success factors for new strategic partnerships. Further, this study presents a model for assessing partner companies to promote increased productivity and improve the relationship between an SI company and its partner. In addition, this model is used to assess partner relationships for a well-known SI company "A". This study explores the feasibility of a new framework model.

  • As building construction projects have been more higher and bigger in scale, the needs for cost reduction, productivity improvement, and reducing of work terms have rapidly increased in recent years. There has been, accordingly, a great emphasis on the necessity of logistics and progress management by well-organized system developed based on the appliance of different management theories. Although highly developed IT technology has contributed to the efficiency and effectiveness in information research and project management, RFID has been merely applied to a single progress or a few types of materials in current management studies, not to the overall process of the projects. This research proposes a consistent and systemized approach for decision making in adopting RFID technology in a construction project to support construction logistics and progress management. With a decision making model that consists of process model and template developed in this research, risks in cost, time, and error in building RFID-based construction logistics and progress management could be minimized.

  • A large number of industry and trade circulation enterprises integrate logistics resource. They give links of product transport to some professional logistics enterprises in order to reduce costs. We call these professional logistics enterprises as the Third-party Logistics. As the development of the computer and internet, the suppliers, buyers and the Third-party Enterprises connect each other with internet. And different company use different management software, so heterogeneous data become a big problem of the information system for Third-party Enterprises. We built the logistics ontology with prot$\'{e}$g$\'{e}$, and translate it in OWL. We also built the rules for Logistics Ontology to improve the limitations of the OWL. Then we design the intelligent system for 3PL Enterprises Distribution Center based on Logistics Ontology and Logistics Rules. At final, we give an example to show the workflow visually.

  • According to the recent report, solar street lamp connected to a non Maximum Power Point Tracking(MPPT) charger, can lead to a system-wide decline in power output with as much as 30%. This paper proposes the charge controller with direct duty ration control for 250W solar street lamp in order to improve the efficiency of photovoltaic from these output power reduction. This paper covers the Pulse Width Modulation(PWM) controller and power conversion topology and analyze the MPPT method for charge controller. The power conversion part consists of push pull converter based on PWM controller using 8bit MCU in order to have lower manufacturing cost. The PWM controller with direct duty ratio control algorithm is constantly tracking the maximum power point of photovoltaic module and increases energy output power. The test results shows 97.1~97.4% MPPT efficiency and the experimental hardware is implemented based on the solar simulator condition for 241W. Thus, the implemented charge controller shows its feasibility for the real application, especially under solar street lamp.

  • IMF위기 이후 여러 가지로 어려움에 처해 있는 경제를 회복하기 위한 돌파구로서 외국기업과 자본의 유치의 중요성이 더해지고 있다. 특히 대규모 기업의 구조조정과 기업들의 투자마인드 위축으로 어려움을 겪고 있는 지방경제를 활성화하기 위한 수단으로서의 투자유치는 먼저, 외국자본의 직접투자를 통하여 단기간에 산업기반을 강화할 수 있고, 제조업의 해외이전에 따른 산업공동화를 방지할 수 있다. 또한 당면한 과제인 고실업을 해소하기 위해서도 필요하다. 정부는 '98, 9. 17. 외국인투자유치촉진법을 제정, 공포하고, 시행령을 마련하여, 국세와 지방세의 감면혜택은 물론 분양가와 조성원가와 차액보조금, 고용보조금, 직업훈련비등의 인센티브를 보완한다. 경상남도의 외국인투자유치전략으로는 경남의 입지적 경쟁우위를 확보할 수 있는 업종을 선정하여 중점유치활동을 전개하고 있다. 이를 위한 구체적 방안으로는 첫째, 투자유치과를 신설하고 전문직공무원을 채용하였고, 민간전문가를 기업으로부터 파견받아 기존 공무원이 담당하기 힘든 부분을 담담토록 하고 있고, 둘째, 진사지방산업단지를 외국인투자지역으로 지정하고 하였다. 셋째, 외국인투자기업에 대한 여러 가지 인센티브를 위하여 경상남도 기업 및 투자 유치조례(안)을 입안중이다. 넷째, 투자유치 타켓기업을 선정하여 집중유치활동을 전개하고 있으며, 다섯째, 경남도내에 이미 투자한 기업에 대한 사후관리를 철저히 하여 경영상의 애로사항 해결에 만전을 다 할 것이다. 지방자치제의 실시로 지방자치단체간의 경쟁이 가열되고 있으나 투자유치활동에 있어서 동서의 협력방안을 모색해 보았으며, 공동투자프로젝트 개발, 공동투자유치설명회 개최, 투자 유치기법의 상호 벤치마킹 등이 필요하다. 결론적으로 외국인 투자촉진법 등 법령의 정비와 외국인 투자유치의 중요성에 대한 인식이 확산되어 외국인 투자유치의 환경이 획기적으로 개선될 것으로 기대된다. 지방자치단체에서도 투자를 기다리던 관행에 탈피하여 입체적인 투자유치노력을 전개해야 할 것이다.
