  • We propose a VSC(Variable Structure Controller) with a PI-type reaching law. In General, conventional VSCs with a reaching law including a discontinuous term have the chattering problem, and thus the system may be unstable due to the disregarded high frequency dynamics in the modeling process. To resolve this problem, the PI-type reaching law is proposed in this paper. The proposed reaching law makes it easy to determine the reaching dynamics as well as the reaching time by utilizing the 2nd-order system analysis. Furthermore, since the discontinous term is not involved in the reaching law, the chattering is considerably reduced. To show the effectiveness of the proposed scheme, the stability of the proposed system is proved by Lyapunov method and the computer simulations are performed for the Ball Balance System.

  • The in-law relationship traditionally plays a major role in Korean marriages and families because parents-in-law prefer to stay with their son under the same roof. The recent spike in the number of intercultural matches in South Korea may be provoking changes in the traditional family experience. The object of this qualitative study was to explore the contextual factors causing conflicts between mothers-in-law and their daughters-in-law in multicultural families. Six mother and daughter in-law dyads from rural areas of South Korea were recruited and interviewed. We found that the mothers-in-law and daughters-in-law had had different motives for the marriage at first. Five major themes emerged from the analysis of the dyadic interviews: the conflicts of the participants were embedded in the alternative family formation, in financial strains and the power structure, barriers in communication, cultural insensitivity and conflicts between value systems, as well as in role conflicts due to differing role expectations and hegemony. In conclusion, the authors of this study suggest that increasing cultural sensitivity and communication skills in immigrant daughter-in-law an Korean mother-in-law relationships will be crucial for a healthy in-law relationship. The need for the availability of Multicultural Family Centers' services in the community was highlighted. In order for mothers-in-law and daughters-in-law to form positive relationships, it is important to facilitate a variety of easily accessible educational programs in the community focusing on fostering the mother-in-law's understanding of the daughter-in-law's perspective.

From Law/Superego to Love: Law, Violence, and the Possibility of Love in Herman Melville's Billy Budd, Sailor (법/초자아에서 사랑으로 -허먼 멜빌의 『빌리 버드』에 나타나는 법, 폭력, 그리고 사랑의 가능성)

  • This essay aims to explore Herman Melville's recognition and resolution of the vicious link between law and violence in his posthumous Billy Budd, Sailor (1924). In order to investigate the issues, this essay refers to Freud, Benjamin, Derrida, Lacan, and Žižek, all perceptive to the uncanny affinity of law and violence. Especially, Žižek's arguments of "superego" as an embodiment of cruel and destructive violence supplementing the official law and of "love" as an ethical possibility beyond the limit of the problematic law are introduced in this study to make Melville's reflection of the inseparableness between law and violence much clearer. John Claggart and Captain Vere embody the legal (superegoic) violence. Claggart even procurs secret enjoyment, in the name of maintaining positive law. Billy Budd discloses another violence defending his justness according to natural law. However, Melville suggests the possibility of suspending the problematic tie of law/violence through "love," as portrayed at the last part of the story. The two final words from Billy and Vere, as a sort of delayed dialogue between them after the event of their secret interview before Billy's hanging, suggest that they finally distance from the obscene nightly law of superego-respectively from outward punitiveness toward Vere and from inward punishment for Vere's excessive enforcement of Billy's hanging-and identify each other's lack as their own. Their love implicated in the last words is for the real other-in Lacan's sense-who discloses the constitutive lack or incompleteness of beings and aporia of the law. This essay's examination of Melville's representations about the superegoic violence as the (im-)possible condition of law and the possibility of withdrawing from it would help us recognize Billy Budd, Sailor as the author's own last word for the possible vision of love cutting the vicious knot of law/violence.

A Study on the Problems of the Doctrine of Utmost Good Faith in English Marine Insurance Law (영국(英國) 해상보험법(海上保險法)에서 최대선의원칙(最大善意原則)의 문제점(問題點)에 관한 고찰(考察))

  • English contract law has traditionally taken the view that it is not the duty of the parties to a contract to give information voluntarily to each other. In English law, one of the principal distinctions between insurance contract law and general contract law is the existence of the doctrine of utmost good faith in insurance law. The doctrine gives rise to a variety of duties, some of which apply before formation of the contract while others apply post-formation. This article is, therefore, designed to analyse the overall structure and problems of the doctrine of utmost good faith in English marine insurance law. The results of analysis are as following : First, the requirement of utmost good faith in marine insurance law arises from the fact that many of the relevant circumstances are within the exclusive knowledge of the assured and it is impossible for the insurer to obtain the facts to make a appropriate calculation of the risk that he is asked to assume without this information. Secondly, the duty of utmost good faith provided in MIA 1906, s. 17 has the nature as a bilateral or reciprocal, overriding and absolute duty. Thirdly, the Court of Appeal in Skandia held that breach of the pre-formation duty of utmost good faith did not sound in damages since the duty did not arise out of an implied contractual term and the breach did not constitute a tort. Instead, the Court of Appeal held that the duty was an extra-contractual duty imposed by law in the form of a contingent condition precedent to the enforceability of the contract. Fourthly, the scope of the duty of utmost good faith is closely related to the test of materiality and the assured is required to disclose only material circumstances subject to MIA 1906, s. 18(1) and 20(1). The test of materiality, which had caused a great deal of debate in English courts over 30 years, was finally settled by the House of Lords in Pan Atlantic and the House of Lords rejected the 'decisive influence' test and the 'increased risk' test, and the decision of the House of Lords is thought to accept the 'mere influence' test in subsequent case by the Court of Appeal. Fifthly, the insurer is, in order to avoid contract, required to provide proof that he is induced to enter into the contract by reason of the non-disclosure or misrepresentation of the assured. Sixthly, the duty of utmost good faith is, in principle, terminated before contract is concluded, but it is undoubtful that the provision under MIA 1906, s. 17 is wide enough to include the post-formation duty. The post-formation duty is, however, based upon the terms of marine insurance contract, and the duty lies entirely outside s. 17. Finally, MIA 1906, s. 17 provides expressly for the remedy of avoidance of the contract for breach of the duty. This means rescission or retrospective avoidance of the entire contract, and the remedy is based upon a fairly crude 'all-or-nothing' approach. What is needed in English marine insurance law is to introduce a more sophiscated or proportionate remedy.

  • The bioethics as a comprehensive and normative control method of life sciences including the technology of advanced medical care, on the one hand, it has modified the conditions for allowing the progress of life sciences. On the other hand, it has put the brakes on attempts of life sciences violating the dignity and value of human beings, natural order. Positively, bioethics presents ethical bases, suggests organization of the legal and institutional conditions, and enables elimination of the legal and institutional obstacles, for the progress of life sciences. Negatively, it has presented justifiable prospects and road maps of life sciences, not to take indiscreet and intemperate turn of violating the dignity and value of human beings, natural order, and its such roles must be carried on.

  • The Rotterdam Rules, which was adopted in December 2008 by UNCITRAL, has underlying intention that it will provide uniform law for the international carriage of goods by sea and modernize transport law reflecting modern transport custom. However, it is also true that there are various conflicting views on the Rotterdam Rules. This article tried to analyze main controversial issues such as scope of application, basis of liability of the shipper and the carrier, exception th the volume contract, legal position of the freight forwarder, delivery of the goods from the both sides of view. The Rotterdam Rules exposes some problems in applying and interpreting the Rules as many people indicated. These problems, I think, mainly due to the extended scope of application and broader range of issues. However, I do not think that the Rotterdam Rules will serious affect to the international transport industry. Furthermore, it is unreasonable to expect perfect Rules satisfying every interests.

  • Egypt has gone through a major metamorphosis following the Egyptian Revolution that began on 25 January 2011. The aim of this article is to analyze the influence of the aforementioned metamorphoses on the Egyptian Arbitration Law and Practice and to shed light on the recent developments of the latter. Whilst positive legislative amendments have been recently achieved with regards to enforcement of arbitral awards, it is crystal clear that the January 2011 Revolution has negatively impacted the jurisprudence of the Administrative Court of the Conseil d'Etat which has annulled several arbitration clauses enshrined in contracts related to privatization. However, save for disputes arising from administrative contracts, Egypt has been and shall remain a friendly seat of Arbitration as it possesses an arbitration-friendly legislation, its Ordinary Judicial Courts are familiarized with international arbitration practice and it has a prominent and famous arbitration Centre.

  • The U.K. Bills of Lading Act 1855 had sought to circumvent the problems arising from the doctrine of privity of contracts. Among the principal factors in the introduction of the Act was the exceptional decision of the court in the case of Grant Norway. The Act 1855 was intended to reverse Grant Norway, but has no effect whatever. As it was not properly drafted, there had been a lot of situations where the Act 1855 was not applicable. In those cases, the courts have implied a contract between cosignee and carrier. This is the effect of the common law Brandt v. Liverpool doctrine. With the enactment of the Carriage of Goods by Sea Act 1992, all of the problems shall be resolved. It repeals the Act 1855 and replaces it with provisions covering not only B/L but also sea waybills and ship's delivery orders. According to the new law, title to sue is now vested in the lawful holder of a bill of lading, the consignee identified in a sea waybill or the person entitled to delivery under a ship's delivery order, irrespective of whether or not they are owners of the goods covered by the document.

  • This writing is for the purpose of investigating the specific character and problem point of China arbitration system which has near 90 years history and overviewing the drift of system improvement which happens recently. The arbitration system of China which traditionally does not acknowledge ad hoc arbitration, unlike most of the other nations that employ The UNCITRAL model law and make it their own legislation, is restrictive to the parties concerned principle of private autonomy considerably. Also the independence of arbitration is delicate, because of a civil characteristic weakness of the arbitral institutions and the intervention of the courts on the arbitration procedure and award. The dual system of domestic and international arbitration which maintains after enforcement of 1994 arbitration law is often to be a primary factor interrupting the development of Chinese arbitration system and making it vulnerable to challenges. The system improvement demand of the recent time reflects this point and makes the arbitration system of China to a international standard rather than now, so it is a desirable direction for China to be as the member of the world economy to be globalization.
