A counter-guarantee is an independent undertaking and it functions in the same way as an ordinary independent guarantee. However, the typical notion of independence which applies to the relationship between the guarantee and the underlying contract cannot be exactly transposed to the relationship between the counter-guarantee and the primary guarantee, because the primary guarantor bears its duties that derive from the mandate. In this respect, this study reviews, with some critics, a Korean appellate court's decision and argues that, in spite of the principle of independence between the counter-guarantee and the primary guarantee, the primary guarantor may not be entitled to reimbursement from the counter-guarantor, if it is objectively evident that the primary guarantor has failed to perform its duty of verifying compliance under the primary guarantor or if it is objectively evident that the primary guarantor knows that it is objectively evident that there was fraudulent calling by the beneficiary under the primary guarantee.

본 연구의 목적은 우리나라에서 주가지수선물이 처음 거래된 1996년 5월 이래 선물의 거래활동과 현물주식시장 변동성의 관계를 분석하는 것이다. 이를 위하여 본 연구는 선물시장 활동 정도를 보여주는 거래량 및 미결제약정수량과 현물 주식시장의 변동성 사이의 동시적 관계 및 인과관계를 규명하고, 추가적으로 주가지수선물의 만기에 따른 현물의 변동성 변화를 살펴보았다. 선물의 거래량과 미결제약정수량은 과거의 자료로부터 예측가능한 부분과 예측불가능한 부분으로 나누어 측정하였고, 현물의 변동성은 GJR-GARCH 모형으로 추정하였다. 선물거래활동과 현물의 변동성의 동시대적 관계 검증 결과, 예측가능 거래량은 예측불가능 거래활동의 일중 변동성과 매우 강한 양의 관계를 가지고 있음을 볼 수 있었다. 반면 선물 거래활동은 대체적으로 현물 변동성과 약한 음의 관계에 있거나 유의하지 않았다. 인과관계 검증 결과, 선물의 거래량이 일중 현물의 변동성을 강하게 선도하고 있는 반면, 선물의 거래량은 밤중 현물의 변동성에 의하여 강하게 선도되고 있음을 알 수 있다. 이는 하루 중 거래가 진행되고 있는 동안에는 선물의 거래량 충격에 의하여 현물의 변동성이 선도되고 밤중에는 현물 변동성에 의하여 선물의 거래량 충격이 선도됨을 의미하는 것이다. 이들 사이의 충격반응 검증결과 어느 한 변수에 대한 다른 변수의 반응은 모두 양의 관계를 가지고 있다. 이를 종합해 보면 거래가 이루어지고 있는 동안에는 선물의 거래가 현물의 변동성을 증가시키고 있었고, 거래가 이루어지지 않는 밤중 사이의 현물의 변동성은 선물의 거래를 증가시키는 관계에 있음을 알 수 있었다. 그러나 선물의 만기 부근에 현물의 변동성이 높아진다는 증거를 찾기는 어려웠다.

The advance of digital contents industry shifts the focus of consumptions; from analogue to digital ones. It gives significant impact on individual life as well as overall society and culture, and it leads to the increased consumption of digital contents. Nevertheless, current digital contents industry fails to secure the sufficient consumer protection systems including relevant rules and laws which regulate the distribution, use, and other transaction activities of digital contents and the efforts, on the part of contents providers, to provide information to consumers and to protect them. Digital contents, by its nature, is different from the existing products so that its nature is likely to cause unique consumer problems totally different from the offline transactions and the electrical transactions of existing products. This study, therefore, aims to identify the possible problems which may be incurred by consumers in their use of digital contents, specify the types of consumer damages, and provide the underlying materials to improve the systems related to digital contents and take legally complementary measures for consumer protection. To identify the types of consumer damages, this study analyzed the results from consumer counselling cases, experts opinion survey, and FGI. For consumer damage cases, this study analyzed the consumer complaints received by open consumer counselling sites of the Korea Consumer Agency and Seoul Electronic Commerce Center. For experts opinion survey, it conducted questionnaire survey of the group of experts from digital contents manufacturers or providers, and those who treated consumer damages directly. For FGI analysis, it organized a panel of students and employees who had used digital contents to understand the types of consumer damages. The results of this study can be summed up as follows. Based on the results from consumer counselling cases, experts opinion survey, and FGI analysis, the consumer damages related to digital contents can be classified, in their nature, into economic or financial damages (25 cases), emotional or psychological ones (15 cases), time-related ones (7 cases), physical ones (4 cases), and privacy-related ones (i.e. leakage of personal data)(3 cases). More specifying the types of damages, damages can be subdivided into contract-, charge-, maintenance-, use-, individual-related ones and other ones. Among them, both contract- and charge-related damages appeared only in the economic or financial damages, whereas user-specific individual damages appeared only in physical and emotional or psychological ones. On the other hand, maintenance- and use-related damages and other ones were observed in both categories of economical or financial damages and time-related ones. Use- and privacy-related damages, in particular, caused emotional or psychological damages.

해외건설업이 국가경제에 기여하는 중추 산업임에도 불구하고, 기존의 해외건설 실적에 관한 연구는 단편적인 동향이나 특정 시점의 시장 점유율을 분석하는데 집중해왔다. 해외건설업은 프로젝트 기반산업으로 분절적이고(fragmented), 여러 다른 업체로 구성되며(heterogeneous), 업황에 따라 시장 구조가 역동적으로 변화하는(dynamic) 특성을 가지고 있어 특정 시점에 대한 정태적 분석과 함께 동태적 시장 변화의 고려가 필수적이다. 본 연구에서는 2000년부터 2017년까지 국내 건설기업이 계약을 체결한 9,173건의 프로젝트 정보를 활용하여 우리나라 해외건설 계약실적 구조를 분석하였다. 산업 차원의 실적정보를 정태적(시장 집중도), 동태적(시장 이동성 및 불안정성)으로 구분하여 분석하였으며, 구체적인 방법론을 기술하였다. 분석 결과, 정태적 측면에서는 국내 건설기업의 해외건설 경쟁구도가 최근 더욱 치열해지고 있으며, 동태적 측면에서는 주요 지역 및 공종을 제외한 대부분의 경우 시장 지위가 미약하고 불안정한 것으로 밝혀졌다. 본 연구는 정태적 동태적 분석의 조합을 통해 건설 관련 주체들의 시장 이해도를 제고하고, 향후 경쟁전략 수립을 위한 기초자료를 제공하였다는 점에서 의의가 있다.

It is a matter for debate that which types of dispute may be resolved by arbitration. This problem is concerning the arbitrability of the subject-matter of a dispute. National laws establish the domain of arbitration. Each state decides which matters may or may not be resolved by arbitration in accordance with its own political, social and economic policy. In response to complexity and diversity of a social phenomenon, the dispute also is various, therefore can not be settled efficiently by means of court adjudication to which applies a law strictly. To overcome such problems we are going to seek to make use of arbitration. According to Korean Arbitration Act Art. 3 (1), any dispute in private laws would be the object of arbitral proceedings. For the promotion of fair and free competition, it is increasingly wide-ranging antitrust legislation across the world. It is matter for debate what can an arbitral tribunal do when confronted with an allegation that the contract under which the arbitration is brought is itself an illegal restraint of trade or in some other way a breach of antitrust law. The underlying question is how to accommodate the conflicting congressional policies favoring resolution of private controversies by arbitration and encouraging private suits to protect the public interests served by the antitrust laws. It is necessary to inquire into the arbitrability of antitrust issues on case-by-case basis, because the types of them are quite diverse. If antitrust issues are the dispute in private laws and the contracting parties agreed to submit to arbitration disputes which have arisen or which may arise between them in the antitrust issues, the antitrust disputes are arbitrable. Not only international antitrust disputes but also domestic antitrust disputes are capable of being resolved by arbitration. When the public interests in the enforcement of antitrust legislation are asserted, it is possible to justify the annulment or the refusal of the recognition or the enforcement of an arbitral award that ignores public policy as a matter of it.

손해보험의 신뢰도이론에서 순보험료로 사용되는 베이즈보험료는 꼬리위험을 반영하지 못한다는 한계점이 있다. 본 논문에서는 꼬리위험측도를 이용하여 할증보험료를 결정하는데 있어 중요하다고 여겨지는 두 가지 주제를 다루었다. 첫째, 위험측도로부터 유도되는 안전할증은 내재된 담보의 위험을 보다 정확히 반영할 수 있으며, 동시에 베이즈보험료만을 사용할 경우 초래될 수 있는 잘못된 의사결정을 피할 수 있음을 보였다. 둘째, 동일한 사전분포가 주어지더라도 서로 다른 조건부손실분포의 꼬리위험 순위와 그에 상응하는 예측분포의 꼬리위험순위는 일반적으로 다를 수 있음을 모수적 모형에 기반하여 보였다. 따라서 안전할증은 조건부손실분포의 위험측도가 아니라 예측분포의 위험측도를 사용해야 함을 알 수 있다.

Under Article 2 of the Uniform Customs and Practice for Documentary Credits (1993 Revision. UCP), letter of credit means an arrangement whereby an issuing bank is to make a payment to a beneficiary, or is to accept and pay bills of exchange drawn by the beneficiary, or authorises another bank to effect such payment, or to accept and pay such bills of exchange, or to negotiate, against stipulated document(s), provided that the terms and conditions of the letter of credit are complied with. In letter of credit operations, all parties concerned deal with documents, and not with goods, services and/or other performances to which the documents may relate (UCP, Article 4). It is important to note that under UCP, if a letter of credit contains conditions without stating the document(s) to be presented in compliance therewith, banks will deem such conditions as not stated and will disregard them (Article 13 c). Section 5-108(g) of the Uniform Commercial Code also contains a similar provision. However on several occasions the Korean Supreme Court held that non-documentary conditions in letter of credit governed by UCP could be regarded as valid, although they were not desirable in the context of letter of credit transactions. The rationale underlying the decisions was that parties to the letter of credit transactions are free to determine the terms and conditions of the relevant letter of credit. After reviewing the relevant provisions of UCP, UCC, the International Standby Practices (ISP98) and the Supreme Court decisions of Korea, the author suggests that we classify conditions that do not require any documents (so called apparent non-documentary conditions) into two categories and treat them differently. There are apparent non-documentary conditions that are consistent with the nature of letter of credit and those which are inconsistent with the nature of letter of credit. In the first category there are two sub-categories, (i) those which are valid and (ii) those which are invalid and thus should be disregarded. In the second category there are two sub-categories, (i) those which are invalid and thus should be disregarded and (ii) those which are valid but deprive the instrument of the nature as letter of credit.

Many presentations of documents are rejected because credits have been incorrectly issued. One reason of rejecting the documents is related with error in application stage of L/C. Errors may take the form of mismatches between the terms of the sales contract and the provisions stipulated in the credit. Thus, Article 5 encourages applicants to make their contribution to the smooth running of the letter of credit process by being unambiguous and brief. Another reason that the banks reject the documents relates to the ambiguity of the term "International Standard Banking Practice" That is to say, UCP500 Art.13 introduced the term "International Standard Banking Practice"(ISBP) without the definition so that one wonder what ISBP is or how ISBP apply in daily work of bankers, examination of documents. From hence, International Chamber of Commerce(ICC) started the work to document ISBP at May 2000, finally approved the result last year and published the publication titled "International Standard Banking Practice for the examination of documents under documentary credits." By applying ISBP in document examination stage, I expect that the freqency of rejecting the documents grow less and bankers' work of examination become easy. On the other hand, ISBP is supplement to UCP500 so that the interpretation of ISBP is made on the basis of understanding of UCP and its underlying principles. So, I reviewed each paragraphs of ISBP on this basis and tried to indicate contradiction between ISBP and UCP500. But because of reading not enough, I failed to search the connotative sense many paragraphs have.

The purpose of this paper is to examine the basic principles for the examination of documents in terms of the basic duty to examine the documents, the time allowed to the banks to examine the documents, linkage among the documents, the originality of documents and their issuers, and the rejection formula of documents. Further this author would look at the changes of particular transport document including bill of lading, charter-party bill of lading and so on. From the seller's perspective, the changes of the principles and individual documents under UCP600 are the most important in the sense that they affect the criteria against which the payment is made. The major changes include the omission of the phrase "with reasonable care", in terms of the basic examination principles, substitute the phrase "five banking days following the day of presentation" for the phrase "reasonable time, not to exceed seven banking days following the days of receipt of documents", introduce the new wording about the linkage between the documents tendered, and make clear the meaning of the originality of documents as well as the rejection formula. For transport documents, even though dealing with bill of lading, charter-party bill of lading, transport document covering at least two different modes of transport, freight-forwarder bill of lading and freight collect transport documents, this paper focuses on the "transhipment" of bill of lading and the definition of charter-party bill of lading. Thus, UCP has been changed several times to reflect the new banking customs and practice. It, however, would not answer every questions which users and banks will raise. These questions may be best answered in the particular underlying contract. The UCP are necessary but not a sufficient instrument for the smooth operation of an international trade transaction. The rules are now out: it remains to be seen what the players do with it.
