Due to the reinforcement of government's DSM(Demand Side Management) policy. Solid State Meter was introduced in Korea since 1993 and it is applied to the high voltage customer exceeding 100kW in order to equalize daily load curve. In recent days, KEPCO has a Plan to use the Solid State Meter which has a data recording and remote meter-reading function for low voltage customer to introduce the real-time pricing system and reduce peak power in the near future. So, this paper suggests the specification and function of Solid State Meter.

The purpose of this paper is to analyze the competitiveness between Busan New Port and Shanghai's New Yangshan Port, on an island 20 miles off the Chinese mainland coast. For this aim, the paper examines backgrounds of Yangshan Port construction and its related projects, namely, Donghai Bridge and Luchao Logistics Park including operation strategies of Yangshan New Deepwater Port. The main results of this paper are as follows: Busan New Port has competitive advantage over Yangshan Port in terms of ideal location, especially in Asia-North America route, and connection between terminal and hinterland logistics park. Because Busan New Port is operated by fully on-dock system. Nevertheless, Yangshan Port has more strength in its centrality, port tariff and port productivity, which are represented by crane productivity, quay productivity and area productivity. Therefore, Korean ports are recommended by transformation from cargo attraction-type to cargo generation-type port through early activation of port logistics center along with Free Economic Zone.

Demand response provides customer load reductions based on high market prices or system reliability conditions. One type of demand response, price-based program, induces customers to respond to changes in product rates. However, there are large-scale general and industrial customers that have difficulty changing their energy consumption patterns, even with rate changes, due to their electricity demands being commercial and industrial. This study proposes an in-house pricing model for large-scale general and industrial customers, particularly those with multiple business facilities, for self-regulating demand-side management and cost reduction. The in-house pricing model charges higher rates to customers with lower load factors by employing peak to off-peak ratios in order to reduce maximum demand at each facility. The proposed scheme has been applied to real world and its benefits are demonstrated through an example.

Trade remedy is the system that additional duty or import quantity restriction would be imposed on the import products, in case that unfair imports damage domestic industry or even proper import products damage significantly domestic industry. The system is secured by the act of unfair trade practice investigation & industrial damage remedy, tariff act, WTO agreement. Anti-dumping duty act is the system that duties are assessed with the equal or less amount of the difference between normal transaction price and dumping price, in case that the product imported under dumping price causes or may cause damages in domestic industry, or the development of domestic industry should be delayed practically. Recently, the problems related with anti-dumping duty imposed as the part of the trade remedy occur frequently. It is necessary to discuss whether the anti-dumping duty act is practically trade remedy which does comply with GATT regulations and WTO agreements as the criteria of international law and is in line with the intent of domestic act in the suffered country, or it does return to protective trade or reduce the protection of consumer. On the basis of this discussion, it would be difficult to impose the antidumping duty on industrial products in order to protect domestic industry, when considering the expected free trade agreements of Korea-US, Korea-China and Korea-Japan. In order to survive under the current severe competition of world trade market, companies should raise the competitiveness by themselves without relying on the current trade acts to provide with a certain protection. This thesis should bring those attentions.

This paper proposed a program of an energy storage system(ESS) for peak shaving of high-speed railway substations The peak shaving saves cost of equipment and demand cost of the substation. To reduce the peak load, it is very important to know when the peak load appears. The past data based load profile forecasting method is easy and applicable to customers which have relatively fixed load profiles. And an optimal scheduling method of the ESS is helpful in reducing the electricity tariff and shaving the peak load efficiently. Based on these techniques, MS. NET based peak shaving program is developed. In case study, a specific daily load profile of the local substation was applied and simulated to verify performance of the proposed program.

This study reviews the methodology for utilizing information technology by which even non-professionalists in FTAs and commodity classification area can perform the determination of commodity classification, with ease and by themselves, by means of easy utilization of the information on commodity classification and FTAs, of importing and exporting goods. This article examines the technological elements and logics, etc. which simulate the commodity classification for utilizing FTAs. To achieve this, the author has developed the technology to support the determination of commodity classification numbers by accumulating the database of examples for classification after analyzing the classification factors by each commodity item. Utilizing this Commodity Classification Determination Supporting System, users can enjoy effects of education as well as consulting. In this regards, the advantages of this system can be enumerated as followings : Firstly, self-checking on commodity classification can be performed. Secondly, time and cost for classification can be saved. Thirdly, comprehensive competitiveness will be enhanced by allowing traders to achieve the benefit of FTA preferential tariff, for they will be able to issue the Certificate of Origins on a more accurate and precise basis of commodity classification.

The main contents of WTO agricultural product agreement are composed of $\circled1$ market access $\circled2$ domestic subsidy and reduction of export subsidy $\circled3$ preferences for developing countries. But there still remains the possibility of laying a protection barrier within WTO regulations. That is to say, with the application of quota system, tariff rate quota system, or different quotas on different countries, and with the practices of government control trade and mark up. This paper is for studying the application of these protection barriers to minimize the impact of agricultural market opening.

The photovoltaic(PV) industry has been growing around the PV advanced countries such as Japan, Germany, Europe and USA. In recent years, China became a strong performer in the world PV market share, increasing solar cell production rapidly The global photovoltaic (PV) market grew by over 40% in 2007, with approximately 2.3GW of newly installed capacity. The global cumulative installed capacity has reached 9GW. The cumulative installed power of PV system in Korea tremendously increased to 74.7MW at the end of 2007. Up to Sep. 2008 The cumulative installed power of PV system in Korea is approximately 377MW. The value chain of photovoltaic in Korea is creating actively. Thus Korea is predicted to see 800MW of modules installed in 2010. Korea's renewable energy is also targeting to take 5% of the total energy consumption by 2011.

It is a right time to improve the Korea Foreign Trade Act(KFTA) as a fundamental law on Rules of Origin(RoO) in the global trade circumstances which are summarized FTA and WTO. The KFTA's RoO constitutes the labelling system of the Country of Origin, the criterion of it, the issuing of certificate of origin and the punishing offender mainly around the importing goods. This study has focused on the problems of KFTA's RoO at the macro and practical level, and proposed the programs to improve the KFTA's RoO about importing, exporting and domestic production goods. KFTA need to create a purpose clause to protect consumers and industries also, and has to be located a general and top position in the RoO of Korea. In the concrete, the labelling system of the Country of Origin has to set limited in the point of minimum necessity view. The criterion of the Country of Origin also has to improve the wholly obtained criterion, the changing in tariff classification criterion, value added criterion and processing operation criterion to harmonize WTO Rules of Origin and FTA Rules of Origin. The punishment ceiling against offender has to raise to guarantee the effectiveness of RoO.

In this study, air conditioning systems include ground source heat pump (GSHP), are evaluated for economic feasibility. The building is modeled an air conditioned for 280kW scale. This analysis is compared with the energy tariff programs of Korea and USA. The objectives of this paper are to evaluate the cost-effectiveness of the GSHP and combined system using Life-Cycle Cost (LCC) analysis, and to carry out the sensitivity analysis of key parameters. The paper considered the cases including the base case of air source heat pump and the other two alternates for comparisons. The combined system is not only a cost-effective way to the low energy consumption but also a way to avoid a high initial investment. The variations of initial investment and energy rates give a significant effect on the total LCC and payback period.
