In the construction industry, projects are becoming increasingly large and complex, involving multiple subcontractors. Traditional centralized coordination techniques used by the general contractors become less effective as subcontractors perform most work and provide their own resources. When subcontractors cannot provide enough resources, they hinder their own performance as well as that of other subcontractors and ultimately the entire project. Thus, construction projects need a new distributed coordination approach wherein all of the concerned subcontractors can reschedule a project dynamically. To enable the new distributed coordination of project schedule changes, I developed a novel agent-based compensatory negotiation methodology, which allows software agents to simulate negotiations on behalf of their human subcontractors. This research formalizes the necessary steps that would help construction project participants to increase the efficiency of their resource use, which in turn will enhance successful completions of whole projects.

The Ministerial Declaration of the 4th WTO Ministerial Meeting at Doha in November 2001 announced the launch of the New Round and a completion date of January 1st, 2005. It agreed to eventually negotiate trade and environment linkage issues, such as the relationship between the WTO rules and Multilateral Environment Agreements and the reduction or elimination of tariff and non-tariff barriers to environmental goods and services. The Committee on Trade and Environment was instructed to pursue work on all items on its agenda within the current terms of reference and to give particular attention to the effects of environmental measures on market access, relevant provisions of the TRTPS Agreement, and labelling requirements for environmental purposes. This means that far the first time, the members of the WTO will discuss and negotiate trade and environment linkage in the framework of multilateral trade negotiation. Korea, from the standpoint of a smaller open economy heavily dependent on international trade, is obliged to overcome the challenges imposed by the environment agenda in the Doha declaration. This study examined the linkage among environment, economic growth and international trade in order to review the possible trade and environment policy implications in Korea. Mutual supportiveness of trade and environment depends much on the effectiveness of trade and environment policy coordination. In this regard, we conclude that the Korean government should provide an appropriate institutional framework to promote closer cooperation among policy makers engaged in negotiations. Trade and environment policy review and environmental impact assessment of trade negotiation should be considered as a work programme of this institutional policy coordination framework.

This paper presents a study regarding a systemic structure that forms a link between heterogeneous terminals and the WebRTC (Web real-time communication) based video-conferencing systems. This system consists of a WebRTC-based terminal, a signal server for the relaying of the necessary signals for media negotiations, an MCU provides an interworking interface for the heterogeneous terminal, and the heterogeneous terminals that interwork with the MCU. This technology enables the interoperability between the WebRTC-based video-conferencing solutions and the legacy devices. In addition to reducing the replacement costs regarding new-technology-based solutions, the existing legacy equipment enables the use of multiparty-conference, thereby increasing the use ability of the conferencing systems.

On 25 December 2000, China and Vietnam signed the Agreement on the Delimitation of the Territorial Seas, EEZs and Continental Shelves in the Tonkin Gulf. Three and a half years after signature, in June 2004, China and Vietnam both ratified a maritime boundary agreement for the Tonkin Gulf (Beibu Gulf) and the agreement entered into force. A potentially complicating factor in the negotiation process was likely to have been the status of the Sino-French Agreement of 1887. In the end, the agreement reached indicated that even if the status of the Sino-French Agreement of 1887 was part of the negotiations, both sides eventually agreed that it would not have an impact on the delimitation of maritime zones in the Gulf of Tonkin. Another crucial issue was the impact of the islands, in particular, the Vietnamese controlled Bach Long Vi Island and Con Co Island. Especially, Bach Long Vi Island was entitled to a half suite of maritime zones (3n.m. EEZ) and would impact the tracing of a line of equidistance in the Gulf of Tonkin. Minor as the point might be, Con Co Island also would have an impact for it would play a fixing terminal point for the boundary. Article 7 of the agreement is about minerals and hydrocarbons of cross-boundary deposit, and if any single geophysical structure of oil and gas or other mineral deposits should straddle the demarcation line, an agreement is to be reached on the development of the structure or deposit and on the most effective manner to equally share the profits resulting from the development.

After more than 15 years of negotiations, China was finally able to achieve the WTO membership, opening up new trade opportunities for China as well as existing WTO members. China accepted a special safeguard mechanism as one of its WTO- plus commitments. And in response, Korea has since introduced China special safeguard rules, which in simple terms, allows an invocation of safeguard measures against Chinese product imports under more lapse conditions than would normally be allowed under the existing general safeguard rules. China also introduced new safeguard rules in November 2001 in an effort to increase transparency in its operation of safeguard measures. However, the current article contends that the new rules pose a serious threat to free trade in the form of the retaliation provision, which enables China to take unilateral retaliatory actions against safeguard measures on Chinese product imports, It indicates that the provision could be operated in an arbitrary manner as the US Super 301, and lead to infringements of WTO disciplines. This paper indicates that the foregoing elements could lead to mort trade disputes between Korea China regarding safeguard measures and subsequent retaliations on the hills of the so called the Garlic War. The current article goes on to offer policy recommendations toward deterring such disputes. First, it recommends a more active invocation of Korea's own retaliatory provision against China's unilateral actions at least to gain negotiating leverage. Second, it sites problems involving China's still conspicuous state-trading practices, and proposes to raise issues again China to induce more faithful implementation of WTO disciplines Final, it stresses the importance of preventing disputes before they arise, and suggests several specific preventive measures.

Environment protection is one of the important political goals along with trade liberalization. Some of the institutions associated with it, however, either hinder trade or exert distorted influence and can arouse trade conflicts eventually. Therefore, harmony between environment protection and trade policy is becoming a crucial issue nowadays. Among the policies for environment, those related to climatic change are regarded as major tasks to deal with in the world commonly. Saying that it is for environment protection, advanced countries impose fines for environment protection on developing countries through border tax adjustments about the items imported from them. However, there is no such agreement about it internationally, so disputes often arise regarding what extent is appropriate as countries cope with it differently in their own way. Disputes about measures for climatic change are highly influential economically, and due to the severe conflicts of interests between states, they often tend to become politicized. Accordingly, we can say that such disputes affect international trade based on the WTO system seriously. When it comes to negotiation for climatic change, we should establish international systems urgently which can work fairly and effectively for all the countries joining in it. Therefore, it is important to examine the treatment of trade restriction measures intended to solve climatic change in international negotiations and establish definite conditions about which measures are allowed and which are not. In conclusion, we should devise rules for environment protection internationally which all the countries in the world can accept and agree on and also make the definite criteria of interpretation as well. Also, through those trade regulations, we should be able to accomplish environment protection globally and at the same time produce synergy, that is, economic growth through trading.

PURPOSES : This study aimed to evaluate the performance of pavement management works and to develop a function for estimating the level of service (LOS) and cost of service (COS) for the systematic and quantitative management of pavement performance in the public sector. METHODS : The International Roughness Index (IRI) was used as the performance index for pavement management. Long-term pavement performance data for a period of 7 years (2007-2014) collected by the National Highway Pavement Management System and historical maintenance budget data published by the South Korean government were used to develop the LOS-COS function. Based on the function, a model for estimating the appropriate budget as well as the network conditions was suggested. RESULTS : There was high degree of correlation between pavement performance and the investment level (R = - 0.74). The developed LOS-COS function suggested that the unit cost to improve the network IRI to 1 m/km was 32.6 billion KRW. Further, the maintenance costs normalized with respect to the LOS levels were LOS-A = 88.2 billion KRW, LOS-B = 55.6 billion KRW, and LOS-C = 23.0 billion KRW. CONCLUSIONS : This study proposes a simple way of developing a LOS-COS function. It also shows how to develop a network budget demand and condition estimation model using the LOS-COS function. In addition, it is the first attempt to evaluate the road maintenance budget in South Korea. It is expected that these results will help in the negotiations between the road managers and budget makers.

This study will examine the social issues and consumer awareness of sharing parking through the method text mining. In this experiment, the topic by keyword was extracted and analyzed using TFIDF (Term frequency inverse document frequency) and LDA (Latent dirichlet allocation) technique. As a result of categorization by topic, citizens' complaints such as local government agreements, parking space negotiations, parking culture improvement, citizen participation, etc., played an important role in implementing shared parking services. The contribution of this study highly differentiated from previous studies that conducted exploratory studies using corporate and regional cases, and can be said to have a high academic contribution. In addition, based on the results obtained by utilizing the LDA analysis in this study, there is a practical contribution that it can be applied or utilized in establishing a sharing economy policy for revitalizing the local economy.

Although the anthracite power plant is an important source of greenhouse gas, research on this type of power plant has not been conducted much. The present study investigated the entire anthracite power plants in Korea and analyzed the emitted gas in connection with GC/FD and a methanizer in order to develop $CO_2$ emission factors. The study also sampled the anthracite to analyze the amount of carbon and hydrogen using an element analyzer, and to measure the calorie using an automatic calorie analyzer. The emission factors computed through the fuel analysis was 30.45 kg/GJ and that computed through the $CO_2$ gas analysis was 26.48 kg/GJ. The former is approximately about 15% higher than the latter. When compared the carbon content factors of anthracite with that of bituminous coal, the value of anthracite was 24% higher Compared with IPCC values, the emission factors by the fuel was 14% higher, and that by the emitted $CO_2$ gas was about 1.2% lower. More research is needed on our own emission factors of various energy-consuming facilities in order to stand on a higher position in international negotiations regarding the treaties on climate changes.

This study aims to know whether the Accreditation of Hospitals can help to improve productivity of hospital and affect the conversion factor. Based on the Malmquist productivity Index, the productivity of accredited hospital improves. There exists an tendency that as the scores of Accreditation rises, productivity increases. Also the higher the productivity, the lower the conversion factors in the rigid statistical evidence. This evidence is independent of hospital classification, geographical distribution, grouping. This evidence supports the productivity index can be included in the fee negotiations. It also means that rather than static efficiency, the multi-year change of productivity information can be usefully combined to set a conversion factor in Korean National Insurance Contract especially in the discussion of the structural change of payment system.
