  • This paper presents a method that registers a lymphoscintigraphy to the real image captured by a CMOS camera, which helps surgeons to easily and precisely detect sentinel lymph nodes for sentinel lymph node biopsy in breast cancer patients. The proposed method consists of two steps: pre-matching and image registration. In the first step, we localize fiducial markers in a lymphoscintigraphy and a real image of a four quadrant bar phantom by using image processing techniques, and then determines perspective transformation parameters by matching with the corresponding marker points. In the second step, we register a lymphoscintigraphy to a real images of patients by using the perspective transformation of pre-matching. To examine the accuracy of the proposed method, we conducted an experiment with a chest mock-up with radioactive markers. As a result, the euclidean distance between corresponding markers was less than 3mm. In conclusion, the present method can be used to accurately align lymphoscintigraphy and real images of patients without attached markers to patients, and then provide useful anatomical information on sentinel lymph node biopsy.

  • A recent trend of global shipping industry adopting Port State Control (PSC) system is recognized as a proficient mechanism in preventing costal traffic accident and protecting marine environment. Disadvantages of Korean shipping companies in PSC inspection are unavoidable as Tokyo MOU imposed priority listed flag to Korea. Having stated above, appropriate research and prompt preparation in compliance with current PSC requirements for the Korean shipping companies have become an immediate need. The objectives of this study are : First, to review in understanding of PSC in overall and foundation of enforcement. Second. to study interaction of international treaties regarding PSC. Third, to compare practical compliance among the countries and to open up a case study on Korean shipping companies in adopting PSC. Last, to suggest direction to the Korean shipping companies the most proficient way in compliance with the current Tokyo MOU requirement. Korean flagged vessels have become prioritized target in PSC inspection as Tokyo MOU imposed priority listed flag to Korea due to high detention rate of its fleet. Disadvantage of a priority listed flag is a burden in its proficient fleet operation. This study suggests solutions to the disadvantages as below. : 1) Change shore management system, and provide continuous & quality education to crew members 2) Form a network in sharing PSC information among the Korean shipping companies 3) Form a centralized function in which government, Korean Shipping register and shipowners can treat problems in a prompt manner.

  • This research investigated the relationship between the corrosion damage characteristics of offshore wind steel substructure and the time of current density application by electrochemical accelerated short-term corrosion test. The galvanostatic corrosion was conducted on the steel specimens in natural seawater with a constant current density ranging from $1mA/cm^2$ to $200mA/cm^2$ for 1 ~ 180 min. Macro and micro observation was carried out on the surface of the corrosion damaged area using SEM and 3-dimensional analysis microscope. The weight loss of the specimens before and after was calculated as the difference between the initial weight prior to corrosion and weight after removal of the corrosion product. It was shown that during galvanostaic corrosion process, the corrosion behavior could be characterized by the onset of pitting corrosion in the early stage and the uniform corrosion in the late stage, showing damage development in the depth direction with the time of current application. The result of the 3D analysis revealed that both damage depth and surface roughness increased with increasing time of current application. The weight loss curves with time showed that a coefficient of determination ($R^2$) was relatively high for the relationship between the time of current application and weight loss. As a result, the degree of corrosion can be controlled by simply varying the time of current application.

  • The review of known decision-making support systems and technologies regarding the possibility of donation and transplantation showed that currently there are no systems and technologies of decision-making support regarding the possibility of donation and transplantation considering civil law. The paper models the decision-making support process regarding the possibility of donation and transplantation, which is a theoretical basis for the development of rules, methods and technology of decision-making support regarding the possibility of donation and transplantation considering civil law. The paper also developed the technology of decision-making support regarding the possibility of donation and transplantation considering civil law as a component of the Unified State Information System for Organ and Tissue Transplantation, which automatically and free of charge determines the possibility/impossibility of donation and transplantation. In the case of the possibility of donation, the admissible type of donation is also determined - over-life or after-life donation - and data about potential donor is entered in the relevant Donor Register. In the case of the possibility of transplantation, if the recipient needs a transplant of one of the paired organs or a part of the organ/tissue, then data about potential recipient are entered in the Transplantation List from both over-life and after-life donor, otherwise, if the recipient needs a transplant of a non-paired organ or both paired organs, then data about potential recipient are entered only in the Transplantation List from after-life donor.

  • 본 논문은 비문과 반려견의 랜드마크를 설정하여 개체를 식별하는 방법에 대해 제안한다. 최근 반려견을 유기하는 현상이 점차 늘어나고 있는 추세이며 유기된 개체 수도 급증하고 있다. 이 유기된 반려견은 야생화가 되어 사람들의 일상생활에 많은 피해를 주고 있어 심각한 문제를 발생시키고 있다. 이에 대한 해결 방법으로 동물등록제가 시행되고 있으나 일부 반려견 주인들은 칩을 삽입하는 등록 방법에 대해 기피하는 현상이 있어 완전한 등록제가 정착되지 않고 있다. 반려견을 등록할 때에 반려견주들의 혐오감이나 기피 현상을 제거하는 것이 반려동물등록제를 정착시킬 수 있을 것이다. 본 논문에서는 이러한 기피 현상을 없애고 반려견주들이 친근하게 반려견을 등록할 수 있도록 비문과 반려견의 랜드마크를 설정하여 개체를 식별하는 방법을 제안하였다.

  • 신한승의 택견은 오늘날 학계에서 '창작된(만들어진) 전통무예'라는 사실이 새롭게 대두되고 있다. 그 이유는 송덕기의 택견 11수의 낱기술을 문화재로 등재하기 위하여 체계화된 무예들의 장점들을 명문화를 통하여 새로운 형태의 전통택견을 창조했기 때문이다. 본 연구에서는 신한승이 택견을 국가 무형문화재로 지정하기 위하여 어떻게 체계화하고 구성하였는지를 살펴보는데 초점을 맞추었고, 다음과 같은 결론과 의의를 찾을 수 있었다. 첫째, 근대 택견의 전수자로 유일한 송덕기 택견의 기술 구성은 일정한 체계가 없는 낱기술 중심의 놀이 형태로 전래 되었으나, 신한승에 의하여 체계적인 구성을 가진 무예로 발전하게 되고, 급기야 무형문화재로 인정받게 되는 쾌거를 이루었다. 둘째, 신한승은 낱기술로 전래되어 오던 택견을 체계화 하면서 유도, 검도, 합기도, 태권도, 가라테의 수련체계와 기술을 일부 차용하여 근대화 시켰다. 이 과정에서 송덕기 택견이 원형대로 전수되지 않고 변형되었다는 비판이 제기되고 있는 실정이다. 셋째, 신한승은 정통 택견에는 없던 급수 구분제도와 실기심사, 태권도의 품새에 해당하는 본대뵈기 12마당 등을 만들고, 스포츠화를 추구하여 현대적인 학습체계와 대중화에 기여하였다. 본 연구를 통해 택견의 원래 형태와 기술변천 및 구성에 대한 시대적 환경적 윤곽을 재조명 할 수 있었으며, 전통화 과정에서 혼재되고 있는 각종 택견 단체들의 논쟁을 이해하는 중요한 참고 자료를 제공할 수 있었다.

  • Korea was highly successful in maintaining a strong tradition of record preservation. However, Japanese imperialism and the Korean war over this century has seen a huge quantity of these once plentiful records either destroyed or relocated overseas. Many of Korea records remain in the custody of foreign archival institutions. Additionally, many records of foreign states concerned with korean affairs, for example, records of the Department of state, in the U.S.A., are of great relevance to Korean modern history. These records which exist in foreign countries are a necessary and invaluable resource in the advancement of Korea studies. After the 1980s, as research interest in Korean modern history increased gradually, much historical material related to Korea was extensively introduced, removed, collected from the U.S.A., Japan, Russia and China etc. by the efforts of pioneering scholars and institutions. Several attempts at collating and publishing this material have been made. Despite this encouraging result, individual scholars and institutions's efforts face problems in relation to removal of records. Firstly, it is repeated nonproductively to remove and collect the same records, for we didn't establish a comprehensive information system, through which the condition of foreign record removal and management is able to be administrated. Secondly, there is no system for arrangement, preservation, use of removed records. For example, finding aids, such as inventory, register, description, isn't prepared for user. A user may usually not understand an accurate context of their creation, preservation removal. Thirdly, almost institution has arranged the removed records among other materials and books. Each institution has a different classification criteria, too. These conditions seem to make a difficulty in national management. This study investigated how the materials for Korea history which has been removed from foreign countries should be managed for effective preservation and use. For these purpose, we investigated the present conditions of removal and management of these materials. Also, we investigated examples of the foreign state, U.S.A. and Japan to have a idea for removal and management policy. Then, This study propose a establishment of information network system as management policy. To administrate removing and managing records effectively, an idea that records belong to the public should be accepted commonly. The policy for management of the record is followings. Firstly, unification of classification is necessary. The records which were removed from foreign countries had better to be classified according to their origins of states and institutions. Secondly, Finding aids should be prepared for user. There are many accession aids such as catalog, register, inventory for user in archives. This will be a efficient method for management. When a record is removed, a card for description of contents must be composed. Thirdly, a digital input and network system establishment is necessary. It will help to manage a condition of removed records. A digital input and management system establishment is not just a project of digitalizing records. At present, various finding aids need to be introduced to make a database for records and archives. An search using only 'search engine' may make a difficulty in finding materials because such method is apt to have too much or little result. So, classification, arrangement, description, response-service should be integrated in these system. The recent technical advancement give a opportunity to realize this idea. Above all, these procedure should be archival process.
