Since the Fukushima nuclear power plant accident in March 2011, critical views on the increase in operation of nuclear power plants including the safety and the economic feasibility thereof have been expanding across the world. In these circumstances, we are to find out solutions to the controversial questions on whether nuclear power plants are economically more feasible than other energy sources, while the safety thereof is fully maintained. Thereby, nuclear power plants will play a key role as a sustainable energy source in the future as well as at present. To measure the social safety level that Korean people are actually feeling after the Fukushima accident, a method of cost-benefit analysis called the Contingent Valuation Method(CVM) was used, whereby we wanted to estimate the amount of expenses the general public would be willing to pay for the safety based on their acceptance rather than the social safety. As a result of calculating the trade-off value of the economic feasibility versus the safety in nuclear power plants through the survey thereon, it caused the nuclear power generation cost to be increased by 4.75 won/kWh. Reflecting this on the current power generation cost of 39.11 won/kWh would increase the cost to 43.86 won/kWh. It is thought that this potential cost is still more competitive than the coal-fired power generation cost of 67 won/kWh. This result will be available as a basic data for the 2nd Energy Basic Plan to be drawn up this year, presenting policy implications at the same time.

Ever since franchising emerged in the industry of distribution, it has been growing explosively in the U.S.A. and all other countries as well. It is a method of expanding a business by licensing independent businessman to sell the franchiser's products and/or services or to follow a format and trade style created by the franchiser using the franchiser's trade marks and trade names. Franchising is a form of business that touches upon many different areas of law including, but not limited to, general contract law, general principles of commercial law, law of intellectual property, competition law, fair trade practices law and other industry specific laws e.g., the Fair Practices in Franchising Act in Korea. Arbitration is a long established, legally recognized procedure for submitting disputes to an outside person(s), mutually selected by the parties, for a final and binding decision. Despite its merits as an alternative dispute resolution, it has been criticized, on the other hand, particularly by franchisees' attorneys on the ground that even though it is required to protect the franchisees against the enforcement of pre-dispute arbitration agreements because of the franchisees' paucity of bargaining power vis-a-vis the franchiser, arbitration cannot afford it. Until recently, however, little has been written about the legal issues pertaining to franchise agreement and arbitration clause contained therein in Korea. This treatise reviews the cases and arguments in relation to the subject especially of the U.S.A., which have been accumulated for decades. The issues addressed herein are the pre-emption by the FAA, the disputes to be arbitrated, the selection and qualification of arbitrators, the place of arbitration hearings and the evidentiary rules applicable, the expenses of arbitration, theory of fiduciary duty and the like, all of which are relevant to franchise agreement.

FTA is acting as a central axis to accomplish the worldwide trade liberalization as FTA has been globally spreading with competition. As the global economic depression and the trend of new protectionism are getting grave, and the trade liberalization of GATT and WTO is getting delayed, FTA is spread as an alternative. FTA is often called as RTA: Regional Trade Agreement(regional free trade agreement) which takes place mainly around the neighbor nations or regular districts, and these days, it is tending towards agreements between long distant nations, so, it's not limited to the regular districts. Among the FTA agreement items, in addition to the customs abolition, the opening and investment liberalization of service market like finance, communication etc., intellectual property rights are included in the government's target range. Korea also is actively proceeding FTA conclusion. Korean government has concluded the agreements with Singapore, european nations beginning from Chile concluded in 2003, and is proceeding more the negotiations with Japan, Canada, Mexico, India etc. Now in 2009, FTA of Korea-United States is actually waiting for just the passage of assembly ratification. But, if FTA becomes effective, because our domestic market should be entirely opened, it is expected that the blow against our domestic agricultural field which is weak, compared with that of the United States, a nation of worldwide agricultural products, is not an ordinary one. According to it, we need a whole plan to cope with, so, the purpose of this study is to suggest the strategy by comparing and analysing the Korean agricultural competitive power, and to find the other development stratagem.

Traditionally, tariffs have been used to protect domestic industries. In particular, a country with more bargaining power makes a punitive threat to maintain a certain level of market share in the market of other country. In this paper, we study the effect of punitive tariffs on an irrelevant industry. In particular, when a country tries to achieve a market share or quantity target in an industry, we examine the effect of threats to impose tariffs on the major export of another industries which are irrelevant to the targeted industry. Using a simple duopoly model, we show that there is a Cournot-Nash equilibrium which supports that a country has an incentive to resolve a trade dispute voluntarily to protect its major export industry under the credible treat of punitive tariffs. This result is mainly due to the fact that the trade policy of a country concerns the aggregate benefits from trade over all its export industries. To obtain this result, this paper employs the linkage between the targeted and irrelevant industries by using the lobby of the irrelevant industry to curb the targeted industry. A lot of recent bilateral trade agreements can be applied to our results.

In October 2005, the Russian government started an investigation if safeguard measures against the importation of Korean sodium cyanide products could be taken. With Russia being a non-WTO member country, the Korean side found themselves in different situation from previous negotiation cases with developed or WTO member countries. Although several elements of trade negotiation theories such as goal setting, bargaining power, and relationship could apply, new constraints of limited information access and uncertainty of administrative procedures should be overcome. Combination of the governmental negotiation, assistance of the Russian consumer group, and the application of related laws led the Russian authority to dismiss the case. I suggest that there be some built-in channels for gathering information of non-WTO member countries.

This paper presents a viewport resolution scaling technique to reduce power consumption in mobile graphic processing units (GPUs). This technique controls the rendering resolution of applications in proportion to the resolution factor. In the mobile environment, it is essential to find an effective resolution factor to achieve low power consumption because both the resolution and power consumption of a GPU are in mutual trade-off. This paper presents a resolution factor that can minimize image quality degradation and gain power reduction. For this purpose, software and hardware viewport resolution scaling techniques are applied in the Android environment. Then, the correlation between image quality and power consumption is analyzed according to the resolution factor by conducting a benchmark analysis in the real commercial environment. Experimental results show that the power consumption decreased by 36.96% on average by the hardware viewport resolution scaling technique.

This paper proposes a new full adder design based on pass-transistor logic that offers ultra-low power dissipation and superior variability together with low transistor count. The pass-transistor logic allows device count reduction through direct logic realization, and thus leads to reduction in the node capacitances as well as short-circuit currents due to the absence of supply rails. Optimum transistor sizing alleviates the adverse effects of process variations on performance metrics. The design is subjected to a comparative analysis against existing designs based on Monte Carlo simulations in a SPICE environment, using the 22-nm CMOS Predictive Technology Model (PTM). The proposed ULP adder offers 38% improvement in power in comparison to the best performing conventional designs. The trade-off in delay to achieve this power saving is estimated through the power-delay product (PDP), which is found to be competitive to conventional values. It also offers upto 79% improvement in variability in comparison to conventional designs, and provides suitable scalability in supply voltage to meet future demands of energy-efficiency in portable applications.

This paper introduces a full duplex single secondary user multiple-input multiple-output (FD-SSU-MIMO) cognitive radio network, where secondary user (SU) opportunistically accesses the authorized spectrum unoccupied by primary user (PU) and transmits data based on FD-MIMO mode. Then we study the network achievable average sum-rate maximization problem under sum transmit power budget constraint at SU communication nodes. In order to solve the trade-off problem between SU's sensing time and data transmission time based on opportunistic spectrum access (OSA) and the power allocation problem based on FD-MIMO transmit mode, we propose a simple trisection algorithm to obtain the optimal sensing time and apply an alternating optimization (AO) algorithm to tackle the FD-MIMO based network achievable sum-rate maximization problem. Simulation results show that our proposed sensing time optimization and AO-based optimal power allocation strategies obtain a higher achievable average sum-rate than sequential convex approximations for matrix-variable programming (SCAMP)-based power allocation for the FD transmission mode, as well as equal power allocation for the half duplex (HD) transmission mode.

Much work has already been done to control and regulate the worldwide problems caused by climate change, particularly the issues on greenhouse gas (GHG) emissions. Carbon dioxide ($CO_2$), having the highest form of concentration among GHGs composed around 1.0 billion tons of emission, and comprises about 98% of the total emissions from the shipping industry. Korean trade mainly rely on the sea transportation. Korean ship tonnages that was brought about by shipbuilders all over the country, continues to grow annually due to the prevailing demands on goods or material supplies and depicting only a small part of the global maritime activity. Nowadays, new build ships coming from the Korean Shipbuilders are being optimized by hull, structure and appendages design, The operational capability of the propulsion and auxiliary machineries in its maximum capacity to achieve the highest possible efficiencies for energy and onboard power use to mitigate $CO_2$ emissions are continually being done through the help of research and development. In this paper, the energy efficiency design index and anboard power capacity of Korean new build ships have been analyzed with response to data collected by ship types, and its respective fuel consumption in relation to $CO_2$ emission results. In response to climate change convention outcome proposals, the best way for the new build ships to become energy efficient is by lowering its operational speed thru adopting the state of the art diesel propulsion engines, patronizing the best sailing practice to lower the transportation cost on the different sea trade routes also helps in $CO_2$ mitigation.
