In this paper we introduce the definition for fuzzy random set by Puri and Ralescu(1985) and show strong laws of large numbers for fuzzy random sets on Banach spaces.

In this paper we obtain strong laws of large numbers for 2-dimensional arrays of random variables which are either pairwise positive quadrant dependent or associated. Our results imply extensions of Etemadi`s strong laws of large numbers for nonnegative random variables to the 2-dimensional case.

A pointed-group is an ordered pair (G,c) where G is a group and c is a specific element of G. Thus a pointed-group is a group together with a distinguish element. The aim of this paper is to generalize the result proved by R.C. Lyndon in [4], that every nilpotent group variety is finitely based for its laws.

By designing and applying the lesson helping to discover the power laws, we tried to investigate the characteristics on the class. To do this, we designed a discovery lesson on the power laws and applied to 54 8th grade students. As results, we could observe the overproduction of monotonous laws, tendency to vary the type of development and increase error to students without prior learning experience, and various errors. All participants failed to express the generalization of $a^m{\div}a^n$ and some participants expressed an incomplete generalization using variables partially for the base or power. We could also observe an error of limited generality or a representation error which did not use the equal sign or variables. In the survey of students, there were two contradictory positions to appeal to the enjoyment of the creation and to talk about the difficulty of creation. Based on such results, we discussed the pedagogical implications relating to the discovery of power laws.

This paper proposes fault tolerant control laws using sliding mode control and adaptation laws for a satellite with reaction wheel faults. Considering system parameter errors and faults uncertainties in the dynamics of satellite, the control laws were designed. It was assumed that only reaction wheel failures occurred as faults. The reaction wheel faults were reflected in the multiply form. Because the proposed control laws satisfy the Lyapunov stability theorem, the stability is guaranteed. Through computer simulation, it was assured that the proposed adaptive sliding mode controller has a better performance than the existing sliding mode controller under unstable angular rates.

The enforcement of international arbitration raises a variety of procedural and related issues in national and international arbitral laws. In addition to the problems it is not easy to understand the rights and enforcement of interim measures by arbitral tribunal. Many countries and international rules allow the arbitral tribunal to submit the interim measures applied by a dispute party. However, interim measures are not recognised and enforced by itself in international commercial arbitration. It has not been completed in the rules of arbitration nationally and internationally. This is the reason why the confirmation of international and national laws is important to effect interim measures practically. In the case of Korean arbitral laws do not include articles of enforcement of interim measures even permit rights of decision of interim measures by arbitral tribunal in the national arbitral laws improperly and unreliably. This paper discuses the deficits of enforcement of interim measures which is submitted the type of award by the arbitral tribunal. The paper also points out and refers the revised model law of arbitration by UNCITRAL in 2006 which was changed to allow the interim award and should be imposed its enforcement of any types of interim measures by the arbitral tribunal in international commercial arbitration.

Product liability is becoming a real issue to exporters, manufacturers world wide. The purpose of this study is to examine the product liability of Korean exporters, manufacturers, etc. under Product Liability Laws and Regulations of China. For this purpose, firstly we deal with the Product Liability Laws and Regulations of China. Secondly we analyze the case study concerning the Product Liability in China. From the analysis of case study, Korean exporters, manufacturers, etc. are required to pay close attention to the following : the correspondence of English with Chinese in the warning phrases, the possibility of application of strict global standard in case of existence of product liability, the proper treatment of evidence in the process of litigation, the application of strict liability and the shift of responsibility for evidence on to a defendant, the observance of procedures prescribed by the country in design and manufacture of the product, the manufacture of product to come up to country standard in quality, the consideration of diverse expression in the preparation of warning sign, the importance of quality control and inspection system in case of local procurement of parts and raw materials, Finally, this paper contributes to help the Korean Exporters, Manufacturers, etc. to build up the proper countermeasures regarding product liability under the product liability regulations of China.

The 21st century is witnessing the explosive increase in the usage of internet and international electronic transactions. Due to the unique characteristics of the electronic information, substantial part of such transaction can and do take the form of cross-border transactions. However, there have not been settled appropriate set of rules applicable to the international electronic transactions. Currently, in respect to e-L/C transactions in international trade, there are laws such as Electronic Transaction Basic Act in our country, E-Trade Promotion Act, E-Signature Law, Act on Promotion of Information and Communication Network Utilization and Information Protection and Marine Charter 5 in the Commercial Law. Nevertheless, a complete legislation, that is a uniform rule for e L/C which could support e L/C transactions fully hasn't been established yet. Accordingly, those laws concerned need to improve to regulate e-L/C transactions. The purpose of this paper is to look into the national status for law readjustment to prepare for a new electronic environment and to use appropriately the e-L/C issued by electronic means, and to conduct a comparative analysis on the related regulations to introduce a pertinent laws and propose related regulations to contribute to the making of effective laws to regulate e-L/C.

Although accidents in the domestic construction industry have been decreased gradually, deaths in the construction sites have been occupied 49.9 percent of the total industry and deaths from fall accident have been accounted for 59.7 percent of the construction industry. In order to prevent fall accident, Occupation Safety and Health Act(OSHA) was enacted for setting management standards and detailed regulations was designed by the Ministry of Employment and Labor. Although government has been pushed for companies and workers to comply the regulations, currently, many domestic construction sites have been violated. On the other hand, in safety-advanced countries such as the United States, Japan, and the EU, industrial accidents have been decreased due to continual application of adapted safety policies according to characteristic in each country. Therefore, it is necessary to analyze laws and polices of advanced countries and apply them to domestic construction sites in order to reduce fall accidents. Therefore, the objective of this study is to compare domestic laws related fall accident with advanced countries laws. In the future, the results of this study will be utilized as a reference to reinforce Occupation Safety and Health Act(OSHA).
