The information content is determined by establishing the system range for each of the FRs and by determing the overlap between system range and the design range (i.e the designer-specified range). However, conventional information content doesn't include designer's intention sufficiently. In this paper, the satisfaction function is presented to embody designer's intention by calculating information contents. The satisfaction function is created in order to deal with the uncertanties involved in determining the design range and the system range in terms of a given physical parameter. So, the satisfaction function help designer to choose the optimal design among many proposed design.

With the increasing attention of the international community on climate change and biodiversity promotion programmes, the Korean government and public agencies are trying to protect and restore the ecosystem of areas protected by law, such as waterfronts, by acquiring private land. However, the inadequate purchase system has caused various problems. In this study, an efficient and systematic land purchase system was developed through ecological evaluation, focusing on the ecological and landscape conservation areas of the Donggang basin. The ecological evaluation was developed by integrating parcel-level evaluation and regional-specific evaluation, and the overall level of ecological function was established and finalized through on-site verification. As a result of verifying the purchase land of 88 parcels, it showed a relatively high agreement of more than 85.2%, and the rest of parcels (non-agreement) were considered to have had an impact on vegetation, crop harvesting, etc. due to seasonal differences in ecological evaluation and field verification. The purchasing system was ranked according to the ecological evaluation grade based on the endangered species and the distance from the core ecosystem. As a result, the purchase priority was systematically drawn up to the 5th rank for a total of 68 parcels for the private lands of Geoeun-ri, Munsan-ri, Deokcheon-ri, Unchi-ri, Gumam-ri, and Suji-ri. This study is expected to contribute to the preservation, restoration and ecological management of purchased land in the protected area in the future by establishing and proposing a systematic land purchase system based on ecological evaluation.

This study was to design the optimal locations of the water level monitoring to quantify the agricultural water use in irrigation area supplied from an agricultural reservoir. In most of agricultural areas without TM/TC (Tele-Monitoring and Tele-Control) or monitoring network, irrigation water have been supplied on conventional experience and agricultural reservoir have been operated based on the operating simulation results by HOMWRS (Hydrological Operation Model for Water Resources System). Therefore, this study quantified the amount of agricultural water use in an irrigation area (Musu Reservoir, Jincheon-gun) by establishing water level monitoring network and analyzed the agricultural water saving effect. According to the evaluation of the economic values for water saving effect, the saving agricultural water of 1.7 million ton was analyzed to have economic values of 0.85 million won as water for living, and 1.78 million won as water for industrial use. It is identified to secure economic feasibility of the new water monitoring network by establishing one monitoring point in the entrance, irrigation area and endpoint through the economic analysis.

Fuel cell systems are a completely different form of electricity source that has been used so far and is an aggregation of multiple technologies with multidisciplinary features that can be operated safely only when gas and electrical safety are being considered. Since fuel cells generate through electrochemical reactions there are difficulties in ensuring electricity safety, power quality assessment, effective control and reliability standards for system faults using conventional inspection techniques and even though they are necessary as a primary means for reduction of CO2 owing to the Climate Convention, electrical safety assessment and measures are required for the prevention of faults in residential facilities. Although small-scaled distributed power supplies can be utilized as important means of peak control and energy management measures, research is required for observing the effects on the system and the development of inspection technology to ensure stable operation, and the electrical safety of residential fuel cell systems need to be assessed and the problems derived for establishing electrical safety standards. From the year 2002, Japan has established laws on technical safety standards and development and rules on the product specifications and standards for the industrialization of hydrogen fuel cells. Also, a lot of effort have been made for the commercialization of fuel cells by building one-stop certification services. Internationally, the IEC TC 105 has established international standards based on fuel cells. In order to protect the national interest, the country should be able to respond accordingly meet global standards. In fact, in Korea, to comply with the international trend, Korea Energy Management Corporation is establishing a certified agenda for fuel cells and Korean Agency for Technology and Standards is enacting technical standards for fuel cells. The current terms of fuel cells are that research has been focused more on the quality and performance of manufactured products rather than stable power operation and maintenance over time. In this paper, by considering the household fuel cell as a power device, the safety standards of the fuel cell system for a reliable operation with the existing power system is being proposed.

This study aims to examine the current procedure of the adequacy review system of public standards for records management developed and disseminated by the National Archives of Korea and to explore improvements to utilize them as basic data to solidify the operation of standards. The study identified the shortcomings of the system with examples of international standards and Korean industrial standards. It also analyzed the history of standardization promoted by the National Archives of Korea. The analysis showed that most of them are simple revisions, such as changes of terminology and standard names according to law amendment. The frequency of standardization by standard also showed a significant difference. In addition, it was found that the adequacy review process or results were not disclosed clearly. As such, the study proposes various improvements to solve these problems, namely, improving standardization for the records management system, establishing detailed procedures for deliberation, and establishing evaluation standards for adequacy reviews.

It is very difficult problem to estimate and evaluate the performance of e-government system which scope and size are large and its effectiveness can not be seen shortly but reveals after several years. It is because the previous offline processes can not be transformed to online ones fully and shortly. For such e-transformation cases, the performance evaluation model should be adjusted and modified gradually as time passes. This paper propose new EEM(E-transformation Evaluation Model) model and methodology to evaluate G2B system that is one of large e-government project. EEM model can derive monetary value of e-transformatized business process areas(online areas). It also estimate the expected effect of offline area that is not yet transformed to online. EEM model consists of standard model, verification model and estimation model with some variables such as evaluation year, evaluation area and data type. By using survey data and database data together it can validate the correctness of the model and derive the effect of the system introduction. This paper also propose EEM evaluation methodology consisting of 5 stages and 10 sub processes to evaluate online and offline effect efficiently. To show the usefulness of this study, we evaluate the performance of Korea G2B system named KONEPS which is famous as a successful e-government case in the world by using the proposed model and methodology. The proposed model and methodology can be applied to different similar areas including e-government projects and large scale information system introduction in private sectors. This study can be also used for establishing appropriate policies about e-government project and informatization issues.
