Seg fog removal is an important issue concerned by both computer vision and image processing. Sea fog or haze removal is widely used in lots of fields, such as automatic control system, CCTV, and image recognition. Color image dehazing techniques have been extensively studied, and expecially the dark channel prior(DCP) technique has been widely used. This paper propose a fast and efficient image prior - dark channel prior to remove seg-fog from a single digital image based on the GPU. We implement the basic parallel program and then optimize it to obtain performance acceleration with more than 250 times. While paralleling and the optimizing the algorithm, we improve some parts of the original serial program or basic parallel program according to the characteristics of several steps. The proposed GPU programming algorithm and implementation results may be used with advantages as pre-processing in many systems, such as safe navigation for ship, topographical survey, intelligent vehicles, etc.

In 2008, North Korea revised its Foreign Economic Arbitration Act. To some extent, the new Act reflected such international standard of arbitration as UNCITRAL Arbitration Rules. In this paper, the said Act will be evaluated, and then cooperation ways of South-North Korea on Inter-Korean Commercial Arbitration will be suggested. In 2007, the Ministry of Unification has designated the Korean Commercial Arbitration Board as Inter-Korean Arbitration Committee and has made efforts to prepare follow-up measures on the two Agreements of Inter-Korean Commercial Arbitration. In 2008 however, the follow-up measures has in fact been suspended. In order to revitalize the Inter-Korean commercial arbitration, some prerequisites must be satisfied. First, Inter-Korean Arbitration Committee for Inter-Korean commercial arbitration should re-open as soon as possible. Second, as North Korea recently shows interest in joining the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards(now so called New York Convention), Governmental Authority of Rep. of Korea should also actively assist and support their joining in New York Convention. Third, both Korean governments should carry out joint study on raising the efficiency of the arbitration system which they will use. Fourth, comparative study on arbitration systems used in both countries should be conducted. Also, it may is very timely to discuss the issue in international arbitration community such as "North-East Asia International Arbitration Conference" or other similar events. In conclusion, continuous study on prevention of commercial disputes between South-North Korea and ways to resolve disputes when they arise should be conducted.

It is difficult to use a recognition algorithm of an image in a foggy environment because the color and edge information is removed. One of the famous defogging algorithm is haze removal by using 'Dark Channel Prior(DCP)' which is used to predict for transmission rate using color information of an image and eliminates fog from the image. However, in case that the image has factors such as sunset or yellow dust, there is overemphasized problem on the color of certain channel after haze removal. Furthermore, in case that the image includes an object containing high RGB channel, the transmission related to this area causes a misestimated issue. In this paper, we purpose an enhanced fog elimination algorithm by using improved color normalization and haze rate revision which correct mis-estimation haze area on the basis of color information and edge information of an image. By eliminating the color distortion, we can obtain more natural clean image from the haze image.

Recently, the interests in the 3D image, generated from the range data and CAD, have exceedingly increased, accordingly a various 3D image database is being constructed. The efficient and fast scheme to access the desired image data is the important issue in the application area of the Internet and digital library. However, it is difficult to manage the 3D image database because of its huge size. Therefore, a proper descriptor is necessary to manage the data efficiently, including the content-based search. In this paper, the proposed shape descriptor is based on the voxelization of the 3D image. The medial axis transform, stemming from the mathematical morphology, is performed on the voxelized 3D image and the graph, which is composed of node and edge, is generated from skeletons. The generated graph is adequate to the novel shape descriptor due to no loss of geometric information and the similarity of the insight of the human. Therefore the proposed shape descriptor would be useful for the recognition of 3D object, compression, and content-based search.

If the existence and effect of the arbitration agreement becomes an issue in international business transactions, it is the key point how we shall determine the applicable law by national rules for the conflict of laws, or by other methods. The argument in determination of the applicable law to the existence and effect of the arbitration agreement is related to regal nature of the arbitration agreement. As there are foreign factors in international arbitration, therefore we must consider such an aspect. Besides, we have to examine whether the general theory of contract is universally applicable to the arbitration agreement. Currently, it is the general trend that the party's autonomy principle is applicable in determining the applicable law for the arbitration agreement. However, it is a difficult problem to recognize the applicable law chosen by the parties, whether it is based on any regal standard(for example New York Convention or the private international law or the essential quality of the arbitration agreement). In the light of the actual transactions, when the parties don't make a choice of the applicable law expressly, it will finally come down to presuming the party's implied intent. Nevertheless, finding the implied intent is a difficult problem. Some argue that we shall presume the choice of applicable law by an objective standard such as a place of arbitration, to prevent too much expansion of the scope of the recognition. But we need to review that this interpretation harmonizes with the principle of party autonomy. Especially, if we desire to detect the vital point where it is most closely linked to the arbitration agreement, we have to inquire how we will decide such a relation by means of any standard. However, as the existing Arbitration Act doesn't offer the solution to these issues, therefore we have to settle these problems through the development of adjudications and theories.
