Since imposing Performance Requirements (PRs) on investors have been conducted as a means to protect a host state's domestic industry in the short run, with its effect on improving the international balance of payments, it has been implemented mostly in developing countries. From the viewpoint of investors, however, PRs hinder free competition and investment activities and have the effect of distorting international trade activities; therefore, they are expected to bring detrimental effects on the host state's economic development in the long run. PRs provided by International Investment Agreements (IIAs) and WTO-TRIMs, too, included many abstract regulations which are grounded on the host state's economic efficiency in the past; however, those PRs are gradually being more concretely specified, shifting to a form of prohibition with the goals of increasing the protection on investors and realizing investment liberalization. Accordingly, when Korea freshly concludes IIAs or revises them afterwards, one should focus more on following the points regarding PRs. First, to protect Korean companies' investment activities, it is advantageous to list the contents of prohibited PRs extensively and concretely and create a stipulation. Second, it is necessary to list the contents of the PRs prohibited and add the phrases for prohibiting "any other similar requirements" explicitly, as well so as to cover the PRs that can appear newly. Third, as in the cases associated with PRs, issuable matters are mostly either the range of applying PRs or the conditions of applying them (relevance or detrimental effects); therefore, it is necessary to classify the cases accumulated by issues and analyze them thoroughly. In conclusion, as this study has analyzed the theoretical characteristics of PRs provided in IIAs and related cases and suggests exquisite theory regarding PRs, it not only lays fundamental grounds for follow-up research but also gives useful and practical guidelines for the parties concerned and the arbitrators according to the ISDS procedure.

With the gradual growth of the electronic commerce various forms of shopping malls are constructed, and their searching methods and function are studied many ways. However, the recent outcome is still inadequate to search for goods for the tastes and demands of customers. To construct the shopping mall on the electronic commerce and help customers with purchasing goods, the efficient interface for the customers to contact the shopping malls should be founded and the customers should be able to search the goods they want. Therefore, in this paper, we designed the Intelligent Integration Agent System (IIAS) using the multi-agent formed by the integration agent which integrates the case based reasoning(CBR) and the rule based reasoning(RBR) and the user agent which manages users' profiles. IIAS performs the rule based reasoning on the subject issue first, then provides the unsatisfying search results from the rule-base reasoning to the customers through the user agent, which enables the search of the goods most similar to the ones that meet the tastes and demands of the customers. That is, the accuracy and the speed has been improved by reasoning with the similarity adjustable integration agent which can pick out the goods of customers wants by modifying the weights of properties according to those of the customers.

Traditional theories of the tensile failure of paper have assumed that uniform strain progresses throughout the sheet until an imperfection within the structure causes a catastrophic break. The resistance to tensile elongation is assumed to be elastic , at first, throughout the structure, followed by an overall plastic yield. However, linear image strain analysis (LISA) has demonstrated that the yield in tensile loading of paper is quite non-uniform throughout the structure, Traditional theories have failed to define the flaws that trigger catastrophic failure. It was assumed that a shive or perhaps a low basis weight area filled that role. Studies of the fracture mechanics of paper have typically utilized a well-defined flaw around which yield and failure could be examined . The flaw was a simple razor cut normal to the direction of tensile loading. Such testing is labeled mode I analysis. The included fla in the paper was always normal to the tensile loading direction, never at another orientation . However, shives or low basis weight zones are likely to be at random angular orientations in the sheet. The effects of angular flaws within the tensile test were examined. The strain energy density theory and experimental work demonstrate the change in crack propagation from mode I to mode IIas the initial flaw angle of crack propagation as a function of the initial flaw angle is predicted and experimentally demonstrated.
