  • The slamming impact pressures at the bottom area of the Open60' are evaluated by the rules and regulations of various organizations - ISO and classification societies. The enhanced performance of the modern racing yacht in terms of speed which achieves well over 20 knots needs special consideration. The calculated design impact pressures are compared a experimental results. Severe difference can be found in these calculation results but the final conclusion shall be obtained after the scantling calculation under the evaluated design impact pressure so far.

  • Objectives : To establish a well organized and systematic oriental medicine classification of headache, the western and oriental medicine diagnosis and treatment systems of headache were reviewed. Methods : The history and development process of western medicine classification of headache were studied. A literature review of oriental medicine classification of headache was done. The characters of each classification systems were assessed. Results : In western medicine, many international societies concerning headache have been established. Through these societies, a classification of headache which can be used by both researchers and practitioners has been suggested. And the suggested classification system is highly recommended to be used in studies in order to increase utilization. As data is accumulated, new versions of the classification system were updated. But in the case of oriental medicine, various classification systems of headache are presented in numerous literatures. But the effort to unify and systemize the oriental medicine headache classification has been in lack. Conclusions : Establishment and utilization of a standardized oriental medicine headache classification system, based on various classifications and detailed descriptions is needed.

  • 2000년대에 들어와서 강력하게 추진되고 있는 국내 학회와 학술지에 대한 평가는 학회와 학술지의 장래를 결정하게 되는데 여기에 대한 한국지구과학회의 대응과 그 결과를 제시하고 앞으로 지구과학이 어떤 방향으로 연구하고 교육해야 하는지를 토의해 보고자 한다. 2002년에 실시된 학술진흥재단 평가에서 한국지구과학회지가 우수하게 평가되어 학술진흥재단의 등재지로 선정되었으며, 한국지구과학회의 정체성을 결정하는 지구과학 학문 분류 (2002년도)가 학술진흥재단에 그대로 반영되었다. 그리고 2003년도부터 국가 학문 분류를 확정하기 위하여 KISTEP(한국과학기술기획평가원)에서 실시한 공청회와 의견 수렴에 적극적으로 참여하여 우리의 학문 분류 안을 관철시켰다. 그리고 2003년도 학술진흥재단학문분류를 위하여 지구과학분야의 학문 분류 안을 제출하였다. 앞으로도 학술지 평가와 학문 분류 조정이 계속적으로 이루어지기 때문에 지구과학의 정체성과 함께 지구과학의 학문 분류에 대하여 지속적으로 연구해야 할 것이다.

  • This paper introduces the mechanical vibration-measurements of vibration on ships(ISO 20283). Regulations and guidelines for vibration of hull structures, propulsion machinery and onboard equipments on ship were established mainly by classification societies or International Association of Classification Societies(IACS). The initial draft of ISO 20283 was proposed by USA and based on US military standards. Though these are not suitable to passenger and merchant ships, many experts have felt the need of the ISO regulation for the vibration measurement on ship. Hence, these standards are re-drafted and reviewed by particulate ISO members. In this paper, authors introduce the important agendas and the controversial items during setup of ISO 20283.

  • The International Association of Classification Societies(IACS) can trace its original back to the International Conference on Load Lines of 1930 and was established in 1968. Long before the formal foundation of IACS, a number of working parties existed to carry out studies of specific topics concerning technical rules of classification. The general terms of reference of the working groups of IACS are to draft unified rules and regulations between Societies, to study safety standards at the request of the International Maritime Organization(IMO) and to prepare unified interpretations of technical regulations of international conventions. As an associate member since 1975, the Korean Resister of Shipping has been actively attending the meeting of IACS working parties. In this paper, summaries of major agenda of the working parties including history of unified requirements and relevant technical tendencies are explained for the purpose of providing better understanding of the rule development.

  • STEP AP218 has a standard schema to represent the structural model of a midship section. While it helps to exchange ship structural models among heterogeneous automation systems, most shipyards and classification societies still exchange information using 2D paper drawings. We propose a feature parameter input method to generate a 3D STEP model of a ship structure from 2D drawings. We have analyzed the ship structure information contained in 2D drawings and have defined a data model to express the contents of the drawing. We also developed a QUI for the feature parameter input. To translate 2D information extracted from the drawing into a STEP AP2l8 model, we have developed a shape generation library, and generated the 3D ship model through this library. The generated 3D STEP model of a ship structure can be used to exchange information between design departments in a shipyard as well as between classification societies and shipyards.

  • Port State Control (PSC) is the inspection of foreign ships in national ports for the purpose of verifying that the condition of the ships and its equipments comply with the requirement of international conventions and the ship is manned and operated in compliance with applicable international laws. On the other hand, check items in PSC are nearly similar to periodical survey of Classification Societies, because they have the same background regarding safety and maritime pollution prevention. The purpose of this study is to develope computer-aided information system for ship inspection item which is useful for effective implementation of Port State Control. For this work, the status of PSC is reviewed, and the related scheme of ship survey system in Classification Societies is investigated. On these bases, a computer software integrated database system and object-oriented technique is developed. The developed system is expected helpful to establish and maintain an effective system of Port State Control.

  • The 5th revision of Korean Classification of Diseases(KCD) became effective on January 1, 2008. It has reflected the changes made to the tenth revision of International Classification of Diseases (ICD-10) between 1998 and 2005 and the suggestions of academic and related societies in Korea. Two important alterations seem to have a major implication in the insurance industry. One would be the official introduction of a Korean version of International Classification of Diseases for Oncology, third edition(ICD-O-3). The borderline ovarian tumor is classified as a borderline neoplasm, which was classified as a malignant neoplasm in the previous edition of International Classification of Diseases for Oncology. The other would be the appearance of non-C-code malignant neoplasm for the diseases, such as polycythemia vera, newly classified as a malignant neoplasm by the current edition of International Classification of Diseases for Oncology. The National Office of Statistics(NSO) adopted the way of implementation used in the Australian Modification of International Classification of Diseases(ICD-10-AM), instead of assigning them into corresponding C code. Overall, the changes made in this revision doesn't seem to have a serious impact on the insurance industry since it has only reflected updates made to ICD-10.

  • Since the screw propellers were adopted as ship propulsion devices, the replacement of propeller shaft due to damage was mostly of fatigue failure due to the alternative stresses [1],[2]. To prevent such a failure, hence, it is suggested that careful attention should be paid to account of the alternative stresses on the design stage of the propeller shafts. In connection with this fact the Ship Classification Societies' Rules are regarded simply as guidance for preliminary determination of the shaft diameter. In this paper, limiting the topic to the small and medium-sized motor ships, an evaluation of the Rules formulae to a theoretical based on Soderberg's correlation [5] between the factor of safety and the resultant stresses obtained by application of the maximum shear theory is done. For this purpose eleven (11) ships built recently in Korea were taken as a species(refer to table 2. in text). In the end the following conclusions are made: (1) In general the Rules formulae give considerably larger size of the propeller shaft diameter than that derived from theoretical calculation, that is, about 7% more in AB and BV Rules, and about 20% more in LR and KR-NK Rules. (2) LR Rule gives the largest size of all, and AB Rule is mostly closed value to the theoretical. (3) The formular of the AB Rule is considered to be of the simplest in utilization and of the reasonable.
