In the complexity and diversity of modern society, there is an urgent need for an information system which can systematically collect, manage and analyze data. Especially in the discipline of nursing, a nursing informarion system is necessary to maximize nursing resources and improve nursing care in the present system which is faced with increases in client needs and multiple changes in hospital environments. This research was done to provide a basis for the development of an integrative nursing information system for the future, by designing dababases items which were extracted from an analysis of the ward nursing information system on general wards excluding the OPD, ICU, OR and CSR with functions using a different system from the wards, and the design of output screen used the database items. The ward nursing information system was analysed through analysis of nursing practice related to recordings, such as the worksheet, kardex, and other nursing practice recordings, on 25 wards. The development of the database was the part of the construction of hospital information system and used the database development life cycle which is related to the system development life cycle. The database development steps included selection of database management system and design of a physical database following the principles of the order communication system which is been developing at Y University Hospital. Conceptual database and Logical database were designed using the base of 25 data items and fields derived from analysing the worksheet, the data items and fields derived from the kardex and other nursing practice recording, from these 19 data base tables were framed through transforming the relational database. Through this process, four types of output material for nursing practice recording which nurses can carry and use during their nursing practice were produced.

The foot and mouth disease and AI were highly contagious. The virus can be transmitted in a number of ways, including close-contact animal to animal spread, long-distance aerosol spread and fomites, or inanimate objects, typically fodder and motor vehicles. A lot of burial sites were constructed in a short time for preventing the rapid spread of the virus. The carcass burial sites have a risk potential because the sites were constructed without any appropriate and systematic management. It resulted from lacking of time, equipments and man power. The carcass burial sites more than 4,700 constructed in 2011. Approximately 7 million poultry and 3.5 million livestock including head of cattle and swine were buried in farm land. It is time to be concerned if the secondary pollutions occur from the burial sites. The environmental impacts should be analyzed for managing the burial sites effectively and minimizing damages and risks to the environment and human health. This study was to analyze environmental impacts of the process of carcass burial construction using a life cycle assessment methodology. All input data of raw materials and energy usage were collected and the inventory was constructed. The results showed that 1 ton of carcass burial of the environmental impacts were $0.51yr^{-1}$ for ADP, 0.09 kg of 1,4DCB-eq for FAETP, 31.17 kg of $CO_2-eq$ for GWP, 0.04 kg of $C_2H_4-eq$ for POCP, 0.06 kg of $SO_2-eq$ for AP.

Recently, global market competition of iron and steel products is ever increasing due to over-supply from increased number of industries in rapidly growing countries, such as China, Brazil, and Indonesia. To occupy the big market, major industries are trying to develop high quality, high performance steel products via developing a new iron and steel making process. In other words, development of a new and innovative steel plant is a key to cope with the tough situation. Design and development for the life cycle of iron and steel making plant is very much complex and multi-disciplinary. In this paper, Plant Systems Engineering (PSE), a tailored SE process for industrial plant based on ISO/IEC 15288 is used for the design of Continuous Casting Process (CCP) Plant system. The CCP is a crucial process in steel making plant, whose design technology is occupied by the advanced foreign companies. For the sake of increasing engineering capability for the design of CCP, we applied PSE Process for the renovation of the existing CCP Process. Through the study, we were convinced that the applied method can be used for other plant systems, and SE is really the way of thinking, design, and development of modern complex and multi-disciplinary systems where high risk factors are present throughout the whole life cycle.

The global warming related to GHG (greenhouse gases) emissions from industries is a major issue globally. Furthermore, GHG emissions from the fishery industries also represent an important issue, as indicated by "The Code of Conduct for Responsible Fisheries" at the Cancun, Mexico, meeting in 1992 and by the Kyoto protocol in 2005. Korea pronounced itself to be a voluntary exclusion management country at the 16th IPCC at Cancun, Mexico, in 2010. However, few analyses of GHG emissions from Korean fisheries have been performed. Therefore, a quantitative analysis of GHG emissions from the major Korean fisheries is needed before guidelines for reducing GHG emissions from the fishing industry can be established. The aim of this study was to assess the present GHG emissions from the Korean Purse seine fishery using the LCA (life cycle assessment) method. The system boundary and allocation method were defined for the LCA analysis. The fuel consumption factor of the purse seine fishery was also calculated. The GHG emissions for the edible fish were evaluated by determining the weights of whole fish and gutted fish. Finally, the GHG emissions required to produce 1kg of whole fish and 1kg of edible fish were deduced. The results will help determine the GHG emissions from the fishery. They will also be helpful to stakeholders and the government in understanding the circumstances involved in GHG emissions from the fishing industry.

This study examines the system and process of battery stored energy in vehicles and suggest the effective area for the use of V2G(vehicle-to-grid) from Jeju Smart Grid Demonstration Project. V2G means technology of electric power transmission from the battery of electric-drive vehicles to state grid. As for the increasing of effectiveness for demand-side control, V2G is a very good alternative. In the U.S., the utilization of electric vehicles is under 40% on average. In this case, we can use he battery of electric vehicle as role of frequency regulation or generator of demand-side resource. V2G, which is the element of Smart Transportation, consists of electric vehicle battery, BMS(battery management system), OBC(on-board charger), charging infrastructure, NOC(network operating center) and TOC(total operation center). V2G application has been tested for frequency regulation to secure the economical efficiency in the United States. In this case, the battery cycle life is not verified its disadvantage. On the other hand, Demand Response is required by low c-rate of battery in electric vehicle and It can be small impact on the battery cycle life. This paper concludes business area of demand response is more useful than frequency regulation in V2G application of electric vehicles in Korea. This provides the opportunity to create a new business for power grid administrator with VPP(virtual power plant).

Small-scale household digesters have been promoted across Asia as a sustainable way of handling manure. The major advantages are that they produce biogas and reduce odor. However their disadvantages include the low recycling of nutrients, because digestate is dilute and therefore difficult to transport, and the loss of biogas as a result of cracks and the intentional release of excess biogas. In this study, life cycle assessment (LCA) methodology was used to assess the environmental impacts associated with biogas digesters in Vietnam. Handling 1,000 kg of liquid manure and 100 kg of solid manure in a system with a biogas digester reduced the impact potential from 4.4 kg carbon dioxide ($CO_2$) equivalents to 3.2 kg $CO_2$ equivalents compared with traditional manure management. However, this advantage could easily be compromised if digester construction is considered in the LCA or in situations where there is an excess of biogas which is intentionally released. A sensitivity analysis showed that biogas digesters could be a means of reducing global warming if methane emissions can be kept low. In terms of eutrophication, farms with biogas digesters had 3 to 4 times greater impacts. In order to make biogas digesters sustainable, methods for recycling digestates are urgently required.

GIS는 속성자료와 관련하여 공간자료를 다루는데 강력한 수단이다. 그러나 GIS는 동적인 계획문제(dynamic planning problems)를 다루는데 있어서 분석기능과 인터페이스기능이 부족하다. 의사결정지원 체계(Decision Support Systems: DSS)는 그래픽사용자인터페이스(Graphic User Interface: GUI)기능, 모델링기능과 데이터베이스기능을 제공하여 GIS의 부족한 면을 보완한다. DSS의 새로운 분류인 공간의사 결정지원체계(Spatial Decision Support Systems: SDSS)는 공간차원의 문제를 취급할 시 표현기능, 기본적인 분석기능, 그리고 공간, 비공간자료 취급기능과 같은 GIS의 기능과 그래픽사용자인터페이스기능, 모델링기능, 그리고 데이터베이스기능과 같은 DSS의 기능을 통합한다. 계획지원체계(Planning Support Systems: PSS)는 SDSS의 기능에 더 진보된 공간분석기능과 시간기능을 추가한다. 이 연구에서는 GIS, 가치공학(value engineering: VE), 그리고 생애주기비용(life cycle costing: LCC)에 의한 토지이용계획에 따른 상수도관망의 용량확장을 위한 PSS의 구축에 초점을 맞추고자 한다. 이러한 PSS는 토지이용계획에 따른 상수도 필요량을 공급하고 도시성장 규제를 위한 일련의 용량확장대안을 작성하고 도시성장에 연관되는 상수도관망의 투자에 관한 문제를 다룬다.
