  • Free-standing structures that are especially high are more likely to receive brain attacks caused by lightning. Since special structures are generally part of national industrial structures, lightning strikes mostly cause socio-economic damage. Lightning protection facilities are installed to prevent such lightning damage, but in 2015, support cables on West Sea bridges were hit by lightning, causing a lot of economic damage. Accordingly, the design of a lightning protection system shall establish protective measures after analyzing the risk of debris falling onto the structure. In this thesis, lightning strikes are analyzed directly in relation to the modeling system that operates the actual information collection system for lightning strikes, depending on the location of the tall, free-standing structures, and practical lightning hazard information is provided by a meteorological station. In addition, we propose monitoring and applying a probability correction rate to the calculation of the lightning risk based on the number of lightning strikes directly reaching the ground in order to obtain an effective lightning risk assessment.

  • Nomenclatural code for fungi was dramatically modified in the 18th International Botanical Congress (IBC) held in Melbourne, Australia in July 2011. Its name was changed into International Code of Nomenclature for Algae, Fungi and Plants (ICN), which was formerly called as International Code of Botanical Nomenclature (ICBN) of the Vienna Code of 2005. The most important change for fungi is abandoning dual nomenclature and introducing one fungus/one name system (2013. 1). Since more than 10,000 species of fungal names should be renamed based on this new classification system (one fungus/one name system), it is challenging to both mycologists and taxonomic users such as plant pathologists and food scientists. Here, we introduced background, progress and future plan for its transition into one fungus/one name system. The new code is allowing electronic-only publication of names of new taxa (2102. 1) and the requirement for a Latin validating diagnosis was changed to allow either English or Latin for the publication of a new name (2011. 1). Furthermore, pre-publication deposit of key nomenclatural information in a recognized repository is mandatory in ICN (2013. 1). The aims of this manuscript are to introduce new code of fungal nomenclature and recent trends in one fungus/one name system to Korean mycological society.

  • In recent years, the development of new technologies using static magnetic fields has increased the possibility of human exposure to these fields and raised some concern as to their possible health effects. In several countries, governmental or other competent authorities have issued exposure limits that are mainly intended for specific uses, i.e., magnetic resonance imaging (MRI) and particle accelerators for high-energy Physics. Since applications of magnetic fields in industry and medicine are likely to grow in the future, thus increasing the possibility of occupational and general public exposure, and since the number of people with ferromagnetic implants and implanted electronic devices that can be affected by the fields is growing, there is a need for international guidelines. In the present papers, guidelines on limits of exposure to static magnetic fields are selected and discussed in order to review the guidelines of the International Non-ionizing Radiation Committee of the International Radiation Protection Association (IRPA/INIRC) for non-ionizing radiation(NIR)

  • In Republic of Korea, there are considerable vulnerability in electrical stimulating swallowing-assist equipments even though they are professional medical equipments and have high penetration rate with heavy frequency of use. Therefore, in this article, we developed Device Management and Safety Diagnosis Manual for Electrical Stimulating Swallowing-Assist Equipments system. For achieving this, we collected and analysed international standard data from international organizations like International Electrotechnical Commission(IEC). After literature reviews, we build maintenance worksheet and equipment procedure manual for electrical stimulating swallowing-assist equipments according to evidences we collected. These manual and protocol would be used as standard process and contribute to sustain accuracy, effectiveness of the devices, also decrease failure rate and assist to save medical documents.

  • This article focused on the meaning of the 1979 Moon Treaty and its future. Although the Moon Treaty is one of the major 5 space related treaties, it was accepted by only 11 member states which are non-space powers, thus having the least enfluences on the field of space law. And this article analysed the relationship between the 1979 Moon Treay and 1967 Space Treaty which was the first principle treaty, and searched the meaning of the "Common Heritage of Mankind(hereinafter CHM)" stipulated in the Moon treaty in terms of international law. This article also dealt with the present and future problems arising from the Moon Treaty. As far as the 1967 Space Treaty is concerned the main standpoint is that outer space including the moon and the other celestial bodies is res extra commercium, areas not subject to national appropriation like high seas. It proclaims the principle non-appropriation concerning the celestial bodies in outer space. But the concept of CHM stipulated in the Moon Treaty created an entirely new category of territory in international law. This concept basically conveys the idea that the management, exploitation and distribution of natural resources of the area in question are matters to be decided by the international community and are not to be left to the initiative and discretion of individual states or their nationals. Similar provision is found in the 1982 Law of the Sea Convention that operates the International Sea-bed Authority created by the concept of CHM. According to the Moon Treaty international regime will be established as the exploitation of the natural resources of the celestial bodies other than the Earth is about to become feasible. Before the establishment of an international regime we could imagine moratorium upon the expoitation of the natural resources on the celestial bodies. But the drafting history of the Moon Treaty indicates that no moratorium on the exploitation of natural resources was intended prior to the setting up of the international regime. So each State Party could exploit the natural resources bearing in mind that those resouces are CHM. In this respect it would be better for Korea, now not a party to the Moon Treaty, to be a member state in the near future. According to the Moon Treaty the efforts of those countries which have contributed either directly or indirectly the exploitation of the moon shall be given special consideration. The Moon Treaty, which although is criticised by some space law experts represents a solid basis upon which further space exploration can continue, shows the expression of the common collective wisdom of all member States of the United Nations and responds the needs and possibilities of those that have already their technologies into outer space.

  • I focused on LVTS compare with Fedwire to advance a research effects in this paper. The Fedwire Funds Service is generally used to make large-value, time-critical payments. The Federal Reserve Banks provide the Fedwire Funds Service, a real-time gross settlement system that enables participants to initiate funds transfer that are immediate, final, and irrevocable once processed. The Fedwire Funds Service is a credit transfer service. While, The LVTS(Large Value Transfer System) is the high value electronic wire system that facilitates the transfer of irrevocable payments in canadian dollars across the country. Through LVTS, funds can be transferred between participating financial institutions virtually instantaneously in a fully collateralized environment. Thus in this article, first of all, I considered features of payment system between LVTS and Fedwire. Second, I analyzed the governing structure and legal background. Third, I focused on the operational policy and risk aversion policy. Lastly, I suggested that the payment and banking system have to assume, with good reason, more efficiently accurately and securely operation together with conclusion.
