2003년 발생한 1.25인터넷 대란을 거쳐 2009년에 발생한 7.7.디도스 공격 등 최근 발생하는 사이버재난의 규모와 피해는 더욱 커지고 있다. 이러한 사이버 재난은 앞으로 스마트폰을 이용한 공격, 클라우드 컴퓨팅의 공격, 스마트그리드에 대한 공격 등으로 새롭게 발전하리라 예상되어지고 있다. 최근 개정된 '재해경감을 위한 기업의 자율활동 지원에 관한 법률'은 자연재난뿐 아니라 사이버재난에 대해서도 재난관리표준 [7] 과 기업재해경감활동계획 수립지침 [8] 의 표준화된 절차와 원칙을 준용할 수 있도록 하고 있다. 따라서 본 논문은 사이버재난과 관련해서 어떻게 기업 재해경감활동 계획을 수립하는가를 보여주고자 한다. 향후 기업 내 사이버재난분야에 대해 동법 제 19조~제 23조와 제26조에 따른 우수기업 인증제도 도입이 현실화 되면 기업 재난관리 업무에 큰 변곡점이 될 수 있을 것으로 전망한다.

The International Standard Banking Practice for the Examination of Documents under Documentary Letters of Credit (ISBP) is the product by the ICC Banking Commission, October 2002. The ISBP is a practical complement to UCP 500, ICC's universally used rules on documentary credits. It explains, in explicit detail, how the rules are to be applied on a day-to-day basis. It fills a needed gap between the general principles announced in the rules and the daily work of the documentary credit practitioner. By using the ISBP, document checkers can bring their practices in line with those followed by their colleagues worldwide. The result should be a significant reduction in the number of documents refused for discrepancies on first presentation. We are convinced that the benefits of the ISBP will not only be of high importance for users of UCP 500, but also that the practices in the ISBP will survive a UCP revision, or will even be included in the next version of the rule (so call "UCP 600"). Though the above-mentioned benefits of the ISBP, there are several troublesome topics that will probably have to wait for a new UCP revision. It will be a challenge for the drafters of a future UCP to find solutions that will further clarify these points.

In the transaction of credits, banks must examine the presentation to determine, on the basis of the documents alone, whether or not the documents appear on their face to constitute a complying presentation. And bank shall each have a maximum of five banking days following the day of presentation to determine if a presentation is complying. This period does not depend on any upcoming expiry date or last day for presentation. Data in a document, when read in context with the credit, the document itself and international standard banking practice, need not be identical to, but must not conflict with, data in i) that document; ii) any other stipulated document; or iii) the credit. When a bank determines that a presentation is complying, it must honour or negotiate. But, when a bank determine that a presentation does not comply, it may refuse to honour or negotiate. When a bank decides to refuse to honour or negotiate, it must give a single notice to that effect to the presenter. That notice must be given by telecommunication or, if that is not possible, by other expeditious means no later than the close of the fifth banking day following the day of presentation.

This study analyzes some important spin-off effects of the provision, UCP600 Article 14(6), through the methodology of the expected utility maximization theory based on the state-contingent commodities model. Some technical implications of this study are as follows. First, the risk-averse beneficiary will choose to present his documents more than 5 days before expiry date by paying a higher risk premium (so-called cure period) for full assurance to cure documentary discrepancies, if expressed economically, he pursues loss reducing activities to the point where the expected marginal product of his activities is less than its marginal cost. Secondly, where the effectiveness of securing cure period is uncertain, the risk-averse beneficiary will choose to present documents just on the expiry date without securing any cure period by paying no risk premium. This study finally suggests the safe harbor standard should be optimal solution only if it is supplemented by the hidden reasonableness standard for balancing the conflicts of interest between beneficiaries and banks.

This investigation presents reviews of many research results on lightning damage to wind turbines and lightning protection strategies from IEC Standard, Europe, USA, Japan and Korea. There have been few studies on lightning protection of wind turbines in Korea, while various investigations have been performed in the other countries. It is necessary to apply some good lightning protection strategies of IEC Standard and the other countries to Korea. Those are as follows: The guideline for lightning protection of wind turbines should be established based on IEC Standards. It needs to be carried out both development of software and experimental studies for understanding the types of lightning damage to wind turbines and compiling the database. In order to minimize the lightning damage to wind turbines, it is a key factor for wind farm owners and researchers to provide the information about the damage cases and wind farm operation technique.

This paper discusses a new algorithm, the PAPANET (Pivot And Probe Algorithm for NETwork optimization), for solving linear, capacitated linear network flow problem (NPs), PAPANET is a variation and specialization of the Pivot And Probe Algorithm (PAPA) developed by Sethi and Thompson, published in 1983-1984. PAPANET first solves an initial relaxed NP (RNP) with all the nodes from the original problem and a limited set of arcs (possibly all the artificial and slack arcs). From the arcs not considered in the current relaxation, we PROBE to identify candidate arcs that violate the current solution's dual constraints maximally. Candidate arcs are added to the RNP, and this new RNP is solved to optimality. This candidate pricing procedure and pivoting continue until all the candidate arcs price unfavorably and all of the dual constraints corresponding to the other, so-called noncandidate arcs, are satisfied. The implementation of PAPANET requires significantly fewer arcs and less solution CPU time than is required by the standard network simplex method implementation upon which it is based. Computational tests on randomly generated NPs indicate that our PAPANET implementation requires up to 40-50% fewer pivots and 30-40% less solution CPU time than is required by the comparable standard network simplex implementation from which it is derived.

As more and more renewable energy resources are connected into the existing power system and their generation capacities are increasing, the need for regulations to minimize their impacts on the power grid is increasingly growing. And minimizing the irregular impacts made by grid-connected wind generators is important, since the output power generated by renewable energy resources can be changed easily by the weather condition and surrounding environment. In South Korea, an operational technical standard for distributed generation is used as a regulation, in which renewable energy sources including wind power are considered as a kind of distributed generation. In this paper, an international standard, IEC 61400-21, for the grid-connected wind turbine generating system(WTGS) will be introduced and a comprehensive and detailed review on the measuring methods of power quality characteristic parameters for WTGS based on the related IEC standards will be presented. Additionally, some prerequisites for applying the international standards to KEPCO system will be proposed.

Recently Korea has stepped into a stage of sluggish development, and the unemployment of young people has become a major issue. Especially in 1998 IMF economic shock was influential in formulating government policy and social economic structure on employment. Restructuring now becomes everyday words and further restructuring is already under way. Owing to the growing economic crisis and resultant unemployment and initial appointment shall be considered conditional. Young job seekers are grappling with mastering their native language and unnecessary experiences. These unnecessary experiences are needless waste of time and money. Educational system in university may be affected by environmental changes in population of students and business crisis. Sometimes the departments made a very low rate of employment may be abolished or merged in university. The government will demand us in the work of reform by doing NCS. The government is now ask to teach, train and employ students on the basis of NCS especially in high-school, job training center, and college and university. NCS has advantages and disadvantages. NCS may reduce waste of time and money to make unnecessary experiences, provide standard course to prepare educational system. It will be a big help to adapt properly and make better employment system. The most negative element of the program is application to humanities and social sciences by the same standard with technology and engineering department in the university. Standardization of each educational course will not react quickly to rapidly changing situations in the future.

In English Law it seems that it is essential to apply the principle of equilibrium in the contract, however, it does not seemed to apply as the general rule of the principle of contract. Especially it seems that English Court didn't pay attention to the principle of equilibrium in 18th century. If one of the party do not appeal the equilibrium of the contract, it does not make any difference even today. However the Court may cancel or withdraw the construction of contract between the parties where the principle of equilibrium is damaged by fundamental problems like just-price. In French Law it seems that they have more wide definition of the principle of equilibrium. The French Court may consider that the application of good faith is the performance of condition of the contract between the parties and has no power to relieve of one party of his expressed obligations or warranty. In German Law, it seems that the principle of good faith is fundamental to take into account interest of the parties. They may agree to supply information or not to interfere with a commercial agent regarding performance and maintenance of the contract.
