무선 메쉬 네트워크에서 비용 인지 다중 경로 DSDV 라우팅 프로토콜

이성웅,정윤원,Lee, Seong-Woong,Chung, Yun-Won 한국정보처리학회 2008 정보처리학회논문지 C : 정보통신,정보보안 Vol.15 No.4

최근, 무선 메쉬 네트워크에서 라우팅 프로토콜에 대한 연구가 활발히 진행되고 있으며 대표적인 proactive 라우팅 프로토콜인 DSDV (Destination-Sequenced Distance-Vector) 라우팅 프로토콜에서는 홉 수가 주요 라우팅 메트릭으로 사용된다. HMP (Hop-by-Hop) DSDV 및 EHMP (Enhanced HMP) DSDV 라우팅 프로토콜에서는 홉 수 및 한 홉 거리 내에 위치한 노드들의 잉여 대역폭을 고려하여 라우팅을 수행하고 있으나, 단대단 라우팅 관점에서 최적이 아닌 경로로 라우팅을 수행하는 단점이 있다. 본 논문에서는 이러한 단점을 극복하기 위해 홉 수 및 단대단 최소 잉여 대역폭을 고려한 CAMP (Cost-Aware Multi-Path) DSDV 라우팅 프로토콜을 제안한다. NS-2를 이용한 성능 분석을 통해 제안하는 라우팅 프로토콜은 홉 수 및 단대단 최소 잉여 대역폭 정보를 적절히 사용함으로써 처리율 및 패킷 전달율의 측면에서 DSDV, HMP DSDV 및 EHMP DSDV 프로토콜에 비해 더 우수한 성능을 가지며 HMP DSDV 및 EHMP DSDV 프로토콜과 같은 수의 관리 메시지를 가지게 됨을 보인다. In wireless mesh network, studies on routing protocols have been actively carried out recently, and hop count is used as a major routing metric in destination-sequenced distance-vector (DSDV) routing protocol, which is a representative proactive routing protocol. Although hop-by-hop multi-path (HMP) DSDV and enhanced HMP (EHMP) DSDV routing protocols perform routing by considering both hop count and residual bandwidth within one hop distance nodes, it has a shortcoming that routing is carried out via non-optimal path from the aspect of end-to-end routing. In order to overcome the shortcoming, a cost-aware multi-path (CAMP) DSDV routing protocol is proposed in this paper, which considers hop count and end-to-end minimum residual bandwidth. Simulation results based on NS-2 show that the proposed routing protocol performs better than DSDV, HMP DSDV, and EHMP DSDV protocols from the aspect of throughput and packet delivery ratio, by appropriately using hop count and end-to-end minimum residual bandwidth information and has the same number of management messages with HMP DSDV and EHMP DSDV protocols.

The board of director system of the modern company has the important position in corporate governance. The board of director passes over his position as the management agency to a corporate management and is evolving into the supervisory agency. The progressive path of the board of director as the management supervisory agency can be approached to two ways based on the relation of the management execution agency: how to structure and how to compose. In the structure problem of the board of director. United States, Germany and France has the different system and development as method of each one. Relating with the reform of the corporate governance, the one board system of the United States is preferred internationally and our country is not the exception. It can be trust that the one board system warrants the management effectiveness which is necessary to the modem enterprise, because the management execution and the management supervisory are combined in organically. In the composition problem of board of director, there are also two approaches of shareholder representative and stakeholder representative related with the essence of the company and to the goal of the board of director. Currently the shareholder capitalism of the United States is exercising influence strongly and the system of the outsider director of a shareholder representative is expanded with the international to include our country. However the board of director system of the United States which considers management effectiveness and shareholder value is embodying the crisis. There are not the experiential cases which the American system of the board of director has increased the profitability of the enterprise, and it apprears from international market that enormous enterprises of the United States is being weakened.

프랑스 무권화증권의 유통성

이성웅(Lee, Seong Woong) 한국증권법학회 2010 증권법연구 Vol.11 No.1

프랑스에서는 무권화증권의 성질과 관련하여 계좌기록의 법적 의미를 권리형식으로 보는가 권리실체로 보는가로 나누어져 있고, 이에 의하여 선의취득 및 항변제한과 같은 유통성법리의 적용 여부도 결정되는 것으로 보인다. 프랑스법 역사상 무권화증권제도는 유가증권의 발전궤도상에 있는 유가증권제도와 연속성을 가지는 법제도로 볼 수 있고 그 유통성을 위한 법리도 후퇴되어야 할 이유도 없다. 유통성의 전제가 되는 ‘증권에의 화체’라는 것도 가만히 보면 유통성의 핵심이 되는 유통의 의사를 표시하는 방식으로서 유통을 가능하게 하는 하나의 형식일 뿐이며 종이 서면에 의한 방식을 절대적으로 고수해야 하는 것은 아니다. 이런 점에서 무권화증권에 대해 유가증권법리를 계승해 나가려는 프랑스의 계좌기록에 대한 화체이론은 관심의 대상이 되기에 충분하다. 특히 계좌기록에 의한 증권을 유체동산으로 보는 마르땡과 무체동산으로 보는 루카스나 라살라스의 법리 전개는 각각 다른 방식으로 무권화증권에 대한 유통성을 인정하려는 노력을 엿볼 수 있다. Relates with the nature of the uncertificated securities, opinions of France devide into tow parts; the formality of the right or the substance of the right as legal meaning of account record. Theirs views connect with applying legal principle of negotiability, the rules of Good Faith Acquisition and Restriction against Personal Defences, in the uncertificated securities. The uncertificated securities system in the legal history of France is the upgraded system for development of the securities and the rule of negotiability shall be maintained in circulation market of uncertificated securities. The incarnation system as the prerequisite of the securities circulation is one of the possible methods for delivering the right on securities, paper as the instrument of incarnation is not absolute way. From this point, the incarnation theory of the account record is a methodology for successful succession of securities rule to the securities which is dematerialized, therefore, worth while to be interesting by us. Specially, Martin, Lucas, Lassalas regard securities of account record as corporeal movables or incorporeal movables and then they try to develop the negotiability of uncertificated securities through each different method.

연구(硏究)논문(論文) : 선하증권상 부지문언과 유통법리

이성웅 ( Seong Woong Lee ) 한국해법학회 2015 韓國海法學會誌 Vol.37 No.2

부지문언이 기재된 선하증권의 유통성에 관한 문제에 대해서는 다음과 같은 접근이 필요하다고 본다. 첫째, 부지문언의 유효성을 따져야 한다. 국제적인 입법과 함께 우리법의 태도도 컨테이너 입고와 같은 운송인이 운송물의 상태와 수량을 쉽게 확인할 수 없는 경우에는 부지문언의 기재가 유효하다는 것을 인정하고 있다고 보아야 한다. 둘째, 부지문언이 기재된 선하증권에도 유통법리가 적용되어 선의취득을 인정할 수 있는가에 대해서는 부지문언이 선하증권의 유가증권성과 양도성 자체를 제한하는 것은 아니므로 여전히 유통증권성을 인정할 수 있고 따라서 선하증권 및 그 목적물에 대한 선의취득이 가능하다고 해야 하고, 단지 운송물의 상태에 대한 항변에 있어서는 부지문언의 문구가 상법상 규정된 문언적 효력을 정지하여 그 상대방이 오히려 운송물의 존재 및 상태에 대하여 입증책임을 부담해야 한다. 부지문언은 증권 상에 기재되므로 물적항변성을 가진다고 해석할 수 있고 따라서 선하증권을 선의로 양도받은 제3의 증권소지인에게도 동일하게 적용되어 증권소지인이 그 입증책임을 부담하게 될 것이다. In Basic, A Bills of Lading has a negotiability and a adoption of the good faith purchase and the cutting off of personal defense as the document of title. But a number of bills of lading have the unknown wording such as “shipper’s load and count” or “said to contain” which mean not to search or confirm of cargo by a shipper. These unknown wording undertakes the role as the exception clause to a carrier and a barricade against a enforcement of right by the holder of bills of lading. Therefore it weaken the negotiability of the bill of lading as a document of title and affect a carrier about the defense for delivering goods. So, this paper analyses each points on the effectiveness of the unknown wording and the acceptances of the principle of negotiability. To deal the problem of effectiveness of the unknown wording, it needs to search the points of international conventions and laws of several foreign nations. The problem on the good faith purchase contains the takings the ownership of the paper of bill of lading and goods which would be a target of a claim represented by the bill. The matter of bills defense involves the problems such as whether the unknown wording gives the carrier a defense against delivering goods written down on bills or not and the feature of the defense is real or not.

회사의 이익 -전환사채발행에 대한 이사의무와 관련하여-

이성웅 ( Seong Woong Lee ) 경상대학교 법학연구소 2010 法學硏究 Vol.18 No.3

What does a corporate interests means? This question is related with a corporate nature. There are law-economic approaches to grasp the modern corporate reality as a contract relation or a team production relation. In compliance with the contract corporation view which regards the corporation as a contractual relationship, the corporation is the nexus of contracts composed of contracts of multiple stakeholders. And the director must specially devote for a shareholder profit among several corporate participants as the agency of the shareholder who has the residual claim on a operating profit. In compliance with the organized corporation view which understands the corporation as the corporate organization, the corporation is the assets of coalition of stakeholders who have the firm-specific investment for team production. And the director as a mediating hierarchy of the interests of stakeholders has the duty to exercise his discretion for the whole corporation interests which means the coalition interests of stakeholders. When we consider the social-economic position which the public corporation roles in modern society, the team production theory and the mediating hierarchy model as the theory specially targeted a large public corporation would be accord with the practice of modern corporation. Therefore the approach based the team production theory and the mediating hierarchy model would be a proper way to analyse the duty of directors on the convertible bond issue by the corporation in SS group as a modern public corporation of large scale, and it would be a best way to find out the reasonable conclusion.
