A parabolic model is presented for the effective calculation of refraction-diffraction of regular water while they are propagating on the water of slowly varying sea bed with currents. Parabolic wave equation has been used in the model, which is derived from a mild-slope equation using Pade' approximation. With the corrections of Kirby's (1986) model some numerical experiments were carried out to analyze the model accuracy.

WTO는 범세계적 글로벌 경쟁상황에서 국가간 무역거래를 제한하고 자원배분을 왜곡하여 결과적으로 세계 후생의 감소를 가져오는 개별 국가들의 관세 및 각종 비관세장벽, 그리고 자원의 효율적 배분을 왜곡하는 각국 정부의 보조금 정책 시정을 위해 창설되었다. 항공기산업에 있어서 보조금 논쟁의 특징은 주로 선-선진국간 분쟁에 국한된다는 점에서 기존의 WTO에서 많은 갈등을 빚고 있는 선-후진국간의 분쟁과는 큰 차이가 있다. 한국이 주도적으로 대규모 개발사업을 추진하면서 정부보조금을 지급할 경우에는 장기적으로 보조금 분쟁에 휘말릴 가능성이 있다. 그러나 미국/유럽간 쌍무협정 체결 내용에서 보듯이 개발보조금 지급 비중이 전체 개발비의 33%이상이 되지 않을 경우는 큰 문제가 없을 것으로 예상되며, 추가적 지원이 필요할 경우에는 직접적 개발비 보다는 관련 지 원인프라 지원을 통해 특정성 문제를 회피할 필요가 있다. 또한 한국은 아직 WTO 민간 항공기 협정 미가입 상태이기 때문에 WTO로부터 당장 규제대상은 아니다. 실제로 WTO 회원 가입 절차는 WTO로부터 요청 후 국내 검토를 거쳐 예비회원가입(2년 소요)-정회원의 절차를 거치게 된다. 또한 보조금 지급에 의한 경쟁자의 산업 피해가 직접적으로 드러날 때까지는 더 많은 시간이 소요되기 때문에 실제로 WTO 제재를 받기까지는 상당한 시간을 확보할 수 있다. 그럼에도 불구하고 WTO 회원이 되면 항공기산업의 육성에 많은 제약이 따르므로 사전적으로 충분한 정부 지원을 통해 조속히 국제경쟁력을 키우는 전략이 필요한 것으로 보인다.

Currently, the most common form of regional economic integration is FTA (Free Trade Area), which is formed by two countries or more as either a bilateral or multilateral agreement. A proposed FTA between Korea and China recently has been re-focused after China concluded its ECFA (Economic Cooperation Framework Agreement) with Taiwan in June 2010. By May 2010, China was the No.1 export partner to Korea (as a Chinese No.2 import partner). Also, Korea and Taiwan trade structure to China is similar and competitive at the same time. So, China-Taiwan ECFA has a significant effect on the trade between China and Korea. As a result, it will hurt Korean industrial production and trade with China. Therefore, the progress and expected issue of a FT A between Korea and China which is prompting will be analyzed. In this situation, the final purpose of this paper is to analyze the impact on a Korea-China FTA Negotiation from the China-Taiwan ECFA.

This paper studies the contribution of imports and inward foreign direct investment (FDI) as a vehicle of technology transfer onto the EU new member states at both macroeconomic and industry level. The paper takes the effectiveness of the recipient's utilization into account by constructing a new index, the so-called Effective Absorption (EA) Index, to measure ability to absorb and utilize the foreign technology in the recipient country. Using data from 12 donors and 10 recipients from 1998 to 2009, the study at macroeconomic level indicates that technical spillovers of foreign research and development (R&D) play more crucial role relatively to domestic R&D on total factor productivity (TFP) growth of the new member states. Imports are found as the major vehicle of technical spillovers rather than inward FDI. The study at industry level is conducted by using data from 17 manufacturing industries of 10 donors and 6 recipients during 1998 to 2009. The empirical results also support the findings at country level. The patterns of technology transfer are different across industries. Nonetheless, technical spillovers exhibit significantly high contribution on TFP growth in high-tech manufacturing industries.

Recently, with the development of interactive communication system, demands for video live streaming service has increased. Live streamers generate revenues from donations, but existing laws are inadequate to handle these donations. Problems arise when minors donate because they have the right of revocation. In the case of donations that request benefits in return, legal characteristics and results are different from unilateral donations. If minors exercise their right of revocation, live streamers must pay back without getting proper compensation for their services. In this paper, we detect the characteristics of bilateral contract in live streaming donation, indicate the harms that live streamers can get, examine precedents and donation processes focusing on cases when minors can not exercise the right of revocation due to deception, and propose revisions that can protect the streamers without invading minors' rights. Through academically identifying ambiguous legal situations and presenting dispute prevention procedures, this paper can bring positive impacts on the online industry.

Tasan Chong Yak-yong has criticized Zhu Xi's metaphysical viewpoints of human being. Therefore he revealed his viewpoint of human being and the theory of moral practice through his thoughts about the Lord of Heaven and human nature with spiritual inclination toward goodness. He has drawn the Lord of Heaven into Confucianism again. Heaven as the Lord endows human being with a nature that enjoys virtues and detests vices. It watches human being's good and evil. Here we can say Heaven is a outer efficient cause of moral behavior. According to Tasan, human being has its own 'self directed weight'自主之權 so that he can make a judgment and decision about what to do. Therefore we have to do manifest this moral inclination which is a inner efficient cause of moral behavior. That is to say, we must follow the order of daoxin道心 inside our mind. If we did go against it, our mind would be uncomfortable. Now through the method of so-called shu恕 we need to put filial piety孝 fraternal respect弟 compassion慈 into practice. These three moral practices represent the spirit of reciprocity in Confucianism. These lead us to make an achievement of ren仁, representative virtue in the theory of moral practice. Our moral practice means the fulfillment of humanity. This is the way to serve Heaven. Tasan insists that theses are the core thoughts of Confucius and Mencius.

Recent studies on the economic effects of trade liberalization and economic integration have emphasized the significant gains associated with product differentiation and scale economies. Securing access to markets in other countries will make it possible to increase product variety and capture scale economies, thus, expanding the gains from trade. Liberalization is also expected to introduce foreign competition into the previously closed market. Concurrently, the liberalization will improve the competitive market environment for firms selling in the domestic market. Firms will be pressed to either exit or reduce cost. The output per firm, then, will increase due to the exit of rival firms, and the average total cost will decline due to the economies of scale. 'Rationalization' of the production process will eventually follow. This paper addresses the economic effects of (counterfactual) bilateral tariff elimination between Korea and Japan. It computationally assesses the gains from liberalization as well as the resource allocations and welfare effects associated with the tariff reduction. The endogenous determination of the key parameters distinguishes this paper from others. The firm's perceived elasticity of demand and elasticity of substitution in the present model are calibrated to be consistent with the base year data. Korea, Japan, and the rest of the world are modeled explicitly. The sectoral coverage of the model includes twenty-three tradable product categories based on three-digit SITC industries and seven nontradable categories based on one-digit SITC industries. Product categories are also classified into perfectly competitive and imperfectly competitive ones. In the imperfectly competitive industries, product differentiation exists at the firm level, while the perfectly competitive industries are characterized by national product differentiation. The simulation results of bilateral tariff reduction are reported. Tariff elimination tends to increase intra-industry trade flows so that the total amount of exports and imports of both countries expand. Yet, Japan is expected to increase the bilateral trade surplus in the wake of the mutual tariff reduction. Terms-of-trade for Korea will not change, while for Japan it will deteriorate. Equivalent variations reflecting the change in consumer surplus (welfare) will favor Korean consumers. Total output, however, will not change substantially, recording 0.5 and 0.6% for Japan and Korea, respectively. An interesting finding in the analysis is that the gains from increased competition and scale efficiency are not as prevailing as expected in theory.

The voluntary agreement between industries and government on the recycling of wastes has been analysed. The agreement is one of the threatened voluntary agreements. Theoretically these agreements make it possible to fulfill recycling goals with minimized cost. It is the objective of this paper to evaluate the efficiency of the voluntary agreement on recycling wastes by examining of Nash Equilibrium. In the first place, the equilibrium of a bilateral agreement between the representative of industries (association of firms) and government will be analysed to confirm if cost minimization strategies by the association result in a sub-game perfect Nash Equilibrium. This is followed by an analysis of a multilateral agreement among the members of the association to see how the equilibrium and efficiency conditions change. We tried to find some implications that the result of the analysis casts on the environmental policy matters.

Encouraged by the investment in the rice paddy, the introduction of new varieties (Tong-Il), and the price support program, there has been great success in increasing rice production. Meanwhile, the demand for rice has decreased rapidly as per capita income continues to rise. Rice self-sufficiency has been attained, and a new over-supply problem is emerging. Moreover, the Uruguay Round Agricultural Negotiation would prohibit government price support for agricultural products. In October the Korean government decides the government purchase amount and support price, which works as the price guideline. All interested parties exert political efforts to influence the decision. The continued increase of the government purchase price of rice due to political pressure pushed the government purchase price above the market wholesale price in 1988. Also, the farmers preferred to sell to the government than to the wholesaler. This has discouraged the market mechanism, and the government is to take over the three functions of the market mechanism: stockpiling, seasonal price fluctuation adjustment, and circulation. Another big increase may cause the government purchase price to rise above the consumer price, which might lead to arbitrage opportunities for the farmers and suffocate the market mechanism. However, the current political situations limits the options for the Korean government. This paper argues that a supply control policy will reduce the social cost resulting from the high level of producer price support, and it proposes several second best policies: First, the production of new varieties should be reduced rapidly. Second, the old rice in the government warehouse should be auctioned or disposed of in order to reduce the government handling and management costs. Third, the acreage diversion program should be launched in order to control rice paddy acreage. Fourth, a social welfare program in rural areas should be introduced, since the share of population over 60 is increasing rapidly. Fifth, instead of the price support which is forbidden by the Uruguay Round, Korea should restructure the agricultural industry by developing new crops, by enhancing productivity and by improving the agricultural infrastructure.

Confucianism's concept of Ye is ruled by the absolute principle of the universe on one hand, and by "the rules of Ye(節文)" and "the rules of ceremony(儀則)", the principle of relative articulation on the other hand. The realizations of the absolute principle of Ye is depending on its usage in everyday life which is fundamentally conditioned by time and space. Thus, Ye's usage can be maximized when the fundamental principle and the condition of its usage make a mutual harmony. Of course, Ye and Ak(樂) are doing complementary roles for each other, since Ye is a principle of a division and Ak is a principle of combining features. However, the essence of Ye can be figured out as the characteristics of mutual reciprocity among things of hierarchy between the classes. Not only in Modern one But also in the medieval society, Ye was not a one-sided force. The essence of Ye does not retain the interests of an individual and the power of a group. If so, the formal aspects of Ye had been distorted. Confucianism demands a strict morality and ethics of a normal person as well as of the ruler. The characteristics of Ye is democratic and open to the condition of time and space. Yegyo should be rooted in everyday lives and realized as a usualness. Therefore, Shirak was an inevitable feature of Yegyo. During the 16th and the 17th century, Ye insinuated into everyday lives of the public in the Korean society. Yulgok Yiyi(李珥)'s Haejuhyangyak(海州鄕約) was estimated as the exemplary feature of Shirak.
