Employing non-associated flow rule and Power-Law failure criterion, the failure mechanisms of tunnel roof in homogeneous and layered soils are studied in present analysis. From the viewpoint of energy, limit analysis upper bound theorem and variation principle are introduced to study the influence of dilatancy on the collapse mechanism of rectangular tunnel considering effects of supporting force and seepage force. Through calculation, the collapsing curve expressions of rectangular tunnel which are excavated in homogeneous soil and layered soils respectively are derived. The accuracy of this work is verified by comparing with the existing research results. The collapsing surface shapes with different dilatancy coefficients are draw out and the influence of dilatancy coefficient on possible collapsing range is analyzed. The results show that, in homogeneous soil, the potential collapsing range decreases with the decrease of the dilatancy coefficient. In layered soils, the total height and the width on the layered position of possible collapsing block increase and the width of the falling block on tunnel roof decrease when only the upper soil's dilatancy coefficient decrease. When only the lower soil's dilatancy coefficient decrease or both layers' dilatancy coefficients decrease, the range of the potential collapsing block reduces.

Trade finance services have been played an important role in the Korea trade development history since 1960's. These days the trade environment is confronted by the 4th Industrial revolution and new trade protectionism. So we need to improve the Korea Trade Finance Services in order to improve Korea trade volume. Bank of Korea(BOK) also revised the Rule of Korea Trade Finance in 2014 and enlarged the trade fund for commercial banks where they handle the trade finance to small and medium enterprises(SME) in 2016. This article handle the current state and problems of Korea trade finance services and suggest the improvement measures as follows; First, the commercial banks, which handle trade finance fund, should improve the customs and practice of judge loan for SMEs. Second, the export volume counting rule for trade loan should harmonize between BOK's Rule and Foreign Trade Management Regulation under the Foreign Trade Act. Third, the processing trade and intermediate trade also can use the trade finance like other trade. Fourth, Trade finance should be in balance between export and import finance to defend the new protectionism. It means that the trade finance should expand to import in the certain conditions. Lastly, the related trade promotion agencies and their employees should improve their skills and abilities for handling trade finance.

International commercial arbitration is a specially formed mechanism for the final and binding settlement of disputes arisen between contracting parties regarding procedures, structures or other contractual relationship agreed by them. It is a resolution system which is processed autonomously by arbitrators who are appointed by contracting parties without involving the national court. If the contracting parties want to settle their disputes by arbitration, there must be a valid agreement. With a valid agreement, the most important concern is which law(called as the substantive law) should be applied in order to determine the rights and obligations of both contracting parties in relation to the dispute. At this point, the substantive law is really important because it is applied to the dispute itself directly during proceedings as well as it plays an crucial role in scrutiny and enforcement of arbitral awards. This article discusses about the substantive law under international commercial arbitration, specially focusing on the regulations of the ICC rules of arbitration, which is the most widely used all over the world and UNCITRAL Model law, which most countries' rule and laws are based on. By discussing how these rules and regulations should be interpreted and applied, it is expected to provide practical help to practitioners when they agree on an arbitration agreement.

The fatigue life is predicted on tensile-shear spot weldment made from Al-Mg alloy sheet with thickness of 0.8mm using Mitchell's method and uniform material law by $B{\ddot{a}}umel$ and Seeger based on local strain approach. The fatigue properties of critical HAZ region are estimated from the tensile property using simple hardness method. To predict the fatigue life of spot weldment, the local stresses and strains at the potential critical region are estimated by Neuber's rule. The predicted fatigue life based on uniform material law using HAZ's material properties provides good results within a factor of 3, conservatively.

Recently, the export claims related to the compliance of the commercial invoice are increasing. This paper aims to review the basic requirements of the invoice, and two theories on the document compliance, i.e., the strict compliance and the substantial compliance, and to analyse the substantial compliance of the invoice through some recent cases under the UCP 500, ICC's opinions and the International Standard Banking Practice (ISBP). As regards the compliance of the invoice, a majority of the cases has held that it must comply strictly with the credit terms ("strict compliance rule"). However, a minority of courts and credit industry standards such as the UCP and ISBP published by ICC take a different approach, infusing the credit law notions such as equity, "substantial compliance rule", etc. The extent of the substantial compliance of the invoice is particularly explained in the above-mentioned invoice paragraphs of the ISBP and supported by a large number of ICC's official opinions. Especially, the parties and descriptions in the invoice must correspond with those in the credit, being not inconsistent with the other documents. Other issues related to invoices such as a tolerance of the quantity, the amount, and the number of originals or copies, etc. must comply with the credit terms substantially.

On 12 July 2016, China's maritime claim to most of the South China Sea (SCS) based on the so-called nine-dash line was rejected by the Arbitral Tribunal, constituted under Annex VII to the UN Convention on the Law of the Sea (UNCLOS) concerning issues in the South China Sea including the legality of the so-called "nine-dashed line", the status of certain maritime features and their corresponding maritime entitlements, together with the lawfulness of certain actions by China which the Philppines, in a case brought in 2013, alleged were violations. As having the Tribunal determined that China's claim had no legal grounds in UNCLOS, thus undermining China's claims, and establishing that China has no exclusive legal rights to control the area roughly the size of India. There are some major implications from the Tribunal's ruling in the Arbitration award. These include implications on: how to delimit the maritime boundary in disputed waters, how to promote maritime confidence-building measures, how to safeguard maritime safety and security, and how to promote the rule of law in the SCS. Since its application of UNCLOS in East Asia, it has been obvious that the only way to resolve maritime disputes in the region is to build strong maritime cooperative partnerships under the auspices of the rule of law.

Contracts of carriage evidenced by bill of lading which are made between carrier and unidentified number of the shipper are to a large extent regulated by statute law such as Hague-Visby Rules and Hamburg Rules. These rules qualifies the contractual liberty of parties and especially restrains the carrier from introducing exemption from his liability beyond those admitted by the Rules. However, these Rules are applied only to goods in respect of which a bill of lading or similar document of title has been issued. In this reason, it is possible that liability of carrier in respect of goods shipped could become an issue where electronic bill of lading is used instead of paper bill of lading because electronic bill of lading is not generally recognised document of title in existing rule. Thus, this article discuss the relation between the carrier who create electronic bill of lading and the Rules regulating liability of carrier. Also, new Rules which has been examining in UNCITRAL will be introduced.

Form requirements particularly for arbitration clauses are widely perceived as an obstacle for efficiently resolving disputes on an international level. The paper discusses the recent suggestion that the freedom of form principle under Art. 11 CISG extended to arbitration, forum selection, or choice of law clauses in international sales contracts and thus superseded any and all formal requirements in this regard. After analysing national and international form requirements with regard to said clauses, the authors elaborate that while dispute clauses are indeed encompassed by the CISG's scope of application, freedom of form under the CISG was neither intended to nor should it apply to dispute clauses. This result is further confirmed by the interplay of the CISG with other international conventions, first and foremost the 1958 New York Convention, as well as a careful analysis of the so called most-favourable-law-approach.

Tourism is a word meaning enjoyable based on tourism order. No matter how free is the journey guaranteed, there is a limit to the orders travellers follow. In other words, constitutionalism suitable for a region or country can be found in any tourist resort at home and abroad. Foreign or local tourism travelling in Korea have tourism-related rules to keep, and people working for tourism and organization of it have also rules. Therefore, a study for the rule of law is needed in aspect of how to improve tourism. Unfortunately, none of those rules of law to be followed by tourist and people working for tourism have not been researched. For instance, any principle of law has not been studied to help improve people-to-people diplomacy and national economy those of which are emphasized by tourism basic law. Finally, a research is needed for law reforms that guide tourism in future.
