Many conventional management methods have emphasized the minimization of required resources along the supply chain. Accordingly, this paper presents a proposed method called the Virtual Design and Construction (VDC)-aided system. It is based on object-oriented resource control, in order to accomplish a feed-forward control monitoring supply chain logistics. The system is supported by two main parts: (1) IT-based Technologies; and (2) VDC Models. They enable the system to convey proactive information from the detection technology to its linked visualization. The paper includes a field study as the system's pre-test: the Scaffolding Works in a LNG Mega Project. The study demonstrates a system of real-time productivity monitoring by use of the RFIDbased Mobile Information Hub. The on-line 'productivity dashboard' provides an opportunity to display the continuing processes for each work-package. This research project offers the observed opportunities created by the developed system. Future work will entail research experiments aimed towards system validation.

The purpose of this study is to identify key obstacles to the adoption of electronic bill of lading and to suggest an effective way to promote the utilization of electronic bill of lading in international trade field. This study finds that all the respondants have not used 'true' electronic bill of lading that is issued and distributed electronically, and most of them agreed the needs of e-B/L adoption, but their intentions to adopt e-B/L remain very low in the present situation. Five obstacles to the adoption of e-B/L were derived from an explanatory factor analysis: 'integration' factor, 'law institution' factor, 'usability' factor, 'economic efficiency' factor, and 'security' factor. Solutions to promote the utilization of e-B/L in international trade field are as follows; Firstly, to endow e-B/L with the legal force through amending relevant laws including the commercial law. Secondly, to conclude the relevant international agreement, and to carry out joint projects between nations are needed. Thirdly, to conduct publicity campaigns is required to increase the understanding of the concepts and benefits of e-B/L to all concerned parties. Fourthly, stable and reliable system must be constructed with high level security. Fifthly, to readjust the service fee of e-B/L system to a realistic level is to be needed in order for user companies to use e-B/L service.

This article introduces and briefly examines the Uniform Rules for Forfaiting (URF)(ICC Publication No. 800), which were prepared by a joint project of the Banking Commission of the International Chamber of Commerce (ICC) and the International Forfaiting Association (IFA), and became effective on January 1, 2013. Forfaiting is a kind of trade financing technic performed by way of a sale and purchase of payment claim between its seller and its buyer, the forfaiter, on a without recourse basis. URF is designed to facilitate global trade finance and embraces all the international payment instruments which are currently used and will be newly developed in the future. URF is expected to be a set of standardized terms and conditions for both the primary and secondary forfaiting markets. In this context, this article first looks into the concept of the forfaiting and certain features and structure of forfaiting transactions. Then this article moves to discussing URF itself. For this it examines (i) the nature and scope of URF and some important definitions provided in URF, (ii) some provisions of URF that apply to the delivery of documents to the forfaiter, the examination, and the acceptance or refusal, of such documents by the forfaiter, and (iii) the payment of purchase price by the forfaiter to its seller, including the matter of "payment under reserve" and repurchase by the seller from the forfaiter. Finally, this article examines liabilities of the parties concerned, before conclusion.

Exploitation of transboundary oil and gas on continental shelves may cause conflicts between or among States concerned due to the physical character of these resources. As oil and gas are fluid, exploitation of such a transboundary oil field by one side may affect other parties in other jurisdictions. However, there is no universal international legal regime on the issue. This article tries to find the international legal regime governing such resources through analysing UN Assembly's resolutions, UNCLOS, international judicial opinions, bilateral agreements and ILC activities relating to transboundary natural resources. As a result of this study, it seems that each coastal State has an inherent sovereign right on its part of the transboundary oil and gas deposit, but this right is not unlimited. Each state involved with the deposit has a duty to cooperate with other states-through information exchange, consultation, and negotiation. Furthermore, the state has an obligation to refrain from unilateral action when there is a possibility of causing irrevocable damage to the interests of the other states.

Abstract. Camilo Dagum proposed several variants of a new model for the size distribution of personal income in a series of papers in the 1970s. He traced the genesis of the Dagum distributions in applied economics and points out parallel developments in several branches of the applied statistics literature. The main aim of this paper is to define a bivariate Dagum distribution so that the marginals have Dagum distributions. It is observed that the joint probability density function and the joint cumulative distribution function can be expressed in closed forms. Several properties of this distribution such as marginals, conditional distributions and product moments have been discussed. The maximum likelihood estimates for the unknown parameters of this distribution and their approximate variance-covariance matrix have been obtained. Some simulations have been performed to see the performances of the MLEs. One data analysis has been performed for illustrative purpose.

Recently, many solution have been suggested to development of plastic products. Among many manufacturing technologies for plastic parts, the injection molding process is very attractive because of its low production cost and short cycle time. In this paper, the plastic ball seat of a ball joint, one of the essential components for automotive suspension or steering system, was studied to enhance its mechanical performance and durability by using PA66 that is reinforced polymeric plastic resin. But ball seat has some trouble in manufacture process. And strength of molded part is not enough to use. For the quality stabilization and reliability of injection molded parts, we designed the mold cavities through analytical simulation software and tested the mechanical performance for the injection molded ball-seat parts. After modification, tensile strength increases by about $13.5\%$. Strength and quality stabilization is improved.

This study analyzes factors that affect the corporate value of Korean companies operating in Latin American countries. Primary factors are associated with characteristics of the host country, the parent company, and subsidiaries. Empirical results show that asset specificity is the main factor influencing firm value. This region is geographically far from Korea and culturally different. Therefore, the source of competitive advantage such as asset specificity should be large enough to offset liability of foreignness for successful entry into the region. This paper also found that joint ventures are more advantageous than direct investments. Joint ventures in Latin American can minimize risk, complement technology and information, and reduce trade barriers.

The practical difficulties of construction will impose many restrictions on the structural design, and the construction method can also provide unexpected ideas for solving design problems. Through the discussion of three issues closely related to construction in the structural design of Wuhan Center, this paper illustrates the importance of in-depth consideration of the construction situations in the structural design stage. The topics of "Connection between Embedded Steel Plates in Steel Plate Composite Shear Wall" and "Connection Joint between Outrigger Truss and Core Wall" are about how to facilitate on-site construction by simplifying and optimizing detail design. The topic of "Adjusting Internal Force Distribution by Optimizing Construction Sequence" is about how to make the construction process a tool for structural design.

The Friction Stir Welding (FSW) is a new joining method that was developed at The Welding Institute (TWI) in England in 1991. It applied heating by the rotational friction and material plastic flow. It was developed as a new joining method to solve the problems of epochally in the welding of Al alloys. In the study, 6000series of Alloy composed of Al-Mg-Si, one of the Al alloys that are utilized for shipbuilding and construction, is selected as a specimen and the numerical is executed against the welded zone of FSW. The material used in this study had the unique properties of strength and anti-corrosion, but since the welded joint of this material is easily softened by the welding heat, FSW is executed and the numerical analysis is carried out around the joint. To examine the mechanical behaviors and properties, F.E.M analysis is executed and the developed thermal-elastic-plastic finite analysis are used.

In many international financing transactions Korean companies are required to issue a guarantee. Thus far, however, legal issues on international guarantees have not been fully discussed in Korea. This is partly because most of the international guarantees are governed by a foreign law such as English law or the laws of the State of New York. In this articles the author examines major concepts or terms and conditions of a typical international guarantee, e.g., language on consideration, primary obligor, joint and several guarantee, unconditional and irrevocable guarantee, continuing guarantee, right of subrogation, representations and warranties, covenant or undertaking, currency indemnity, assignment, participation, governing law and jurisdiction clause, etc. For reference, standard forms of a guarantee and a standby letter of credit are attached to the article. In examining the terms and conditions, the author compares them with similar or equivalent concepts under Korean law. The author further discusses some Korean law issues that may arise under international guarantees governed by a foreign law. These issues include the application of the ultra vires doctrine under Article 34 of the Civil Code of Korea, the validity of an international guarantee which a Korean company has issued in violation of the guarantee ceiling set under Article 10 of the Law on Monopoly Regulation and Fair Trade of Korea and the validity of an international guarantee which a Korean party has issued in violation of the Foreign Exchange Transaction Law. In addition, the author discusses some issues under a so-called independent guarantee and a standby letter of credit. In this regard, reference is made to the Uniform Rules for Demand Guarantee (URDG), International Standby Practices (ISP98) and the Convention on Independent Guarantees and Stand-by Letters of Credit adopted by the United Nations in 1995. Finally, the author examines major terms and conditions of typical comfort letters and discusses some legal issues, such as the binding force of the comfort letter. In dealing with the issues the author underscores that to the extent the issues are not properly dealt with by an international norm such as Uniform Customs and Practice for Documentary Credits or ISP 98, the issues must be analyzed by reference to the governing law of the relevant instrument.
