In pharmaceutical clinical trials as human material research, the collection, use, storage and provision of human materials must be in accordance with the criteria stipulated in 「Bioethics and Safety Act」, except in the case that some criteria about it is in the law related to clinical trials such as 「Pharmaceutical Affairs Act」 and 「Enforcement Rule on Safety of Drugs, etc.」 so these take precedence over. Under 「Bioethics and Safety Act」, the core aspect of the legal standard for obtaining informed consent is the use of statutory form . The use of statutory form ensure that both those who obtain informed consent and those who give it can know the contents contained this form as well as recognize its importance. Thus, the person who has the right to informed consent can sign the statutory form after correct understanding of the contents. In reality, however, some researchers and IRB members determine that only the main informed consent form is to be used because most of contents on statutory from are included in the main informed consent form. Some other researchers and IRB members judge that the use of statutory form is not needed if human materials may only be used for laboratory testing and the rest will not be stored and provided for future use. Most of these determination and judgement is based on the interpretation of the Korea National Institute for Bioethics Policy(hereafter, KoNIBP) on IRB Information Portal Site. But, it is questionable whether the KoNIBP's interpretation is legally valid and the KoNIBP is the legal entity having authority to interpret existing statute. In some cased not only using the main informed consent form including enough information about the collection, use, storage and provision of human materials but also collecting necessary minimum human materials, and discarding the rest, unusing the statutory form may not cause the problem to respect and protect the research participant's rights. Therefore, the provision stipulating the criteria about the use of statutory form as the legal standard of obtaining informed consent that applies all human material research without exception should review to revise. At least, straighten out the confusion surrounding whether or not the statutory form is to be used, before the revision of related provision, considering the logical opinions of some researchers and IRB Members, the Ministry of Health and Welfare as the legal entity having authority to interpret existing statute should represent its opinion about permission of the acceptable exceptions.

가상 세계의 공유 개념은, 특히 사용자들이 인터넷 같이 대규모 네트웍을 통해 지역적으로 분산된 경우는 복제가 수용할 수 있는 상호작용 성능을 제공하기 때문에 각 사용자의 사이트에 정보를 복제함으로써 확장된다. 그러나, 다수의 동시 갱신은 replicas간의 일관되지 않은 뷰를 일으키게 될 것이다. 따라서, 동시성 제어가 복제자들간에 일관된 상태를 유지하도록 하기 위한 중요한 요소가 된다. 우리는 단지 대상 객체의 주변에 있는 사용자들만이 소유권 요청을 다중 전송하게 하는 확장성 있는 예측기반 동시성 제어 스킴을 제안했었다. 이 작업에서, 우리는 모든 사용자들이 동일한 속도론 가지고 가상 세계를 이동한다고 가정했다. 이것은, 그러나, 좀더 사실성을 더하기 위해 사용자가 가상 세계와 상호작용을 할 매 그들의 이동속도를 변경하도록 하는 네트웍 게임같은 네트웍 가상 환경에서는 너무 common 하다. 본 논문은 다양한 속도를 가진 사자를 지원하기 위한 확장을 제안한다. 확장된 스킴은 다른 속도의 수만큼의 다중 Entity Radii를 가지며 각 속도를 가진 사용자에게 분리된 큐를 할당한다. 각 큐는 다음 소유자 후보를 예측하기 위해 동시에 예측을 수행하고 선택된 후보들간에서 최소의 Predicted Collision Time을 가지는 최종 후보자가 선택된다. 이는 사용자의 속도에 기반을 둔 적절한 Entity Radius를 사용함으로써 소유권의 timely advanced transfer과, 다른 이돔 속도와 latency를 가지는 사용자들 간의 간섭을 줄임으로써 공정(공평)한 소유권 양도, 그리고 불필요한 소유권 전송을 줄임으로써 놓은 예측 정확도를 제공한다.성을 지닌 AMMQL 학습법은 로봇축구와 같이 끊임없이 실시간적으로 변화가 일어나는 다중 에이전트 환경에서 특히 높은 효과를 볼 수 있다. 본 논문에서는 AMMQL 학습방법의 개념을 소개하고, 로봇축구 에이전트의 동적 위치 결정을 위한 학습에 어떻게 이 학습방법을 적용할 수 있는지 세부 설계를 제시한다.다.으로서 hemicellulose구조가 polyuronic acid의 형태인 것으로 사료된다. 추출획분의 구성단당은 여러 곡물연구의 보고와 유사하게 glucose, arabinose, xylose 함량이 대체로 높게 나타났다. 점미가 수가용성분에서 goucose대비 용출함량이 고르게 나타나는 경향을 보였고 흑미는 알칼리가용분에서 glucose가 상당량(0.68%) 포함되고 있음을 보여주었고 arabinose(0.68%), xylose(0.05%)도 다른 종류에 비해서 다량 함유한 것으로 나타났다. 흑미는 총식이섬유 함량이 높고 pectic substances, hemicellulose, uronic acid 함량이 높아서 콜레스테롤 저하 등의 효과가 기대되며 고섬유식품으로서 조리 특성 연구가 필요한 것으로 사료된다.리하였다. 얻어진 소견(所見)은 다음과 같았다. 1. 모년령(母年齡), 임신회수(姙娠回數), 임신기간(姙娠其間), 출산시체중등(出産時體重等)의 제요인(諸要因)은 주산기사망(周産基死亡)에 대(對)하여 통계적(統計的)으로 유의(有意)한 영향을 미치고 있어 $25{\sim}29$세(歲)의 연령군에서, 2번째 임신과 2번째의 출산에서 그리고 만삭의 임신 기간에, 출산시체중(出産時體重) $3.50{\sim}3.99kg$사이의 아

In this paper, we propose AST-AET(Average valid Start Time-Average valid End Time) data migration strategy based on the storage structure where temporal data is divided into a past segment, a current segment, and a future segment. We define AST and AET which are used in AST-AET data migration strategy and also define entity versions to be stored in each segment. We describe methods to compute AST and AET, and processes to search entity versions for migration and move them. We compare average response times for user queries between AST-AET data migration strategy and the existing LST-GET(Least valid Start Time-Greatest valid End Time) data migration strategy. The experimental results show that, when there are no LLTs(Long Lived Tuples), there is little difference in performance between the two migration strategies because the size of a current segment is nearly equal. However, when there are LLTs, the average response time of AST-AET data migration strategy is smaller than that of LST-GET data migration strategy because the size of a current segment of LST-GET data migration strategy becomes larger. In addition, when we change average interarrival times of temporal queries, generally the average response time of AST-AET data migration strategy is smaller than that of LST-GET data migration strategy.

Since IFC (Industry Foundation Classes) 4 is based on the representation of 3D elements for an architecture project, and does not define standardized shapes for civil projects such as roads, bridges, and tunnels etc, it has limitations in securing interoperability for exchanging a shape information model for the civil projects. Besides, since road facilities have a linear reference, which is modeled along the center alignment, it is difficult the designers to create a standardized 3D road model. The aim of this study is to configure structure elements and their attribute for a road in the perspective of 3D design for developing a shape information model for the road. To solve these issues, this study analyzes the design documents, which consist of a road design handbook, guide, specifications and standards, and then extract shape elements and their attributes of road structures. Such shape elements are defined as an entity item and we review a hierarchical structure of a road shape defined by a virtual road model. The detailed elements and their attributes can be utilized as a 3D shape information model for constructing BIM (Building Information Modeling) environment for Infrastructures. Besides, it is expected that the suggested items will be utilized as a base data for extending to IFC for a road subdividing the detailed shapes, types and attributes for road projects.

Plant engineering companies create or refer to requirements documents for each related field, such as plant process/equipment/piping/instrumentation, in different engineering departments. The process-related requirements document includes not only a description of the process but also the requirements of the equipment or related facilities that will operate it. Since the authors and reviewers of the requirements documents are different, there is a possibility that inconsistencies may occur between equipment or parts design specifications described in different requirement documents. Ensuring consistency in these matters can increase the reliability of the overall plant design information. However, the amount of documents and the scattered nature of requirements for a same equipment and parts across different documents make it challenging for engineers to trace and manage requirements. This paper proposes a method to analyze requirement sentences and calculate the similarity of requirement sentences in order to identify semantically identical sentences. To calculate the similarity of requirement sentences, we propose a named entity recognition method to identify compound words for the parts and properties that are semantically central to the requirements. A method to calculate the similarity of the identified compound words for parts and properties is also proposed. The proposed method is explained using sentences in practical documents, and experimental results are described.

While networks of many countries around the world are actively connected with the establishment of ICT-based infrastructure, diplomatic activities are also evolving into various diplomatic forms that are different from traditional diplomacy before. In particular, in the process, public diplomacy activities that focus on subjects other than the government and new diplomatic areas are accelerating. This study identifies the current state of public diplomacy that has emerged as a representative type of new diplomatic style and derives policy implications for the revitalization of global governance. The analysis was attempted based on data generated mainly on the main contents of various diplomatic activities by each entity, and the future direction of public diplomacy was sought. In particular, the subject of diplomacy is becoming more diverse, and most of all, various activities are being carried out based on the world stage due to changes in diplomatic means. Most of all, they understood that all the people are playing the role of private diplomacy, and that the roles and capabilities of local governments are becoming stronger. Global governance needs to be built to revitalize public diplomacy, and support policies need to be continued by expanding the role of public diplomacy and various topics.

Most battleship warfare M&S systems run relatively slow and the simulation results are often unfair since the system should interact with human operators(controller and/or gamer). To deal with these problems, we have proposed the agent-based battleship warfare M&S system which interact with multiple agent systems instead of human operators. Agent-based M&S system may be able to efficiently support the analysis of effectiveness and/or the operational tactics development of given warfare by providing autonomous reasoning capabilities without the intervention of human controller. To do this, the paper propose the design concept and methodology using the advanced modeling and simulation framework as well as autonomous agent design principle. Several simulation tests performed on the battleship warfare case study on Korea Yellow sea will illustrate our techniques.

Natural Language Question Answering (NLQA) and Prescriptive Analytics (PA) have been identified as innovative, emerging technologies in 2015 by the Gartner group. These technologies require knowledge bases that consist of data that has been extracted from unstructured texts. Every business requires a knowledge base for business analytics as it can enhance companies' competitiveness in their industry. Most intelligent or analytic services depend a lot upon on knowledge bases. However, building a qualified knowledge base is very time consuming and requires a considerable amount of effort, especially if it is to be manually created. Another problem that occurs when creating a knowledge base is that it will be outdated by the time it is completed and will require constant updating even when it is ready in use. For these reason, it is more advisable to create a computerized knowledge base. This research focuses on building a computerized knowledge base for business using a supervised learning and rule-based method. The method proposed in this paper is based on information extraction, but it has been specialized and modified to extract information related only to a business. The business knowledge base created by our system can also be used for advanced functions such as presenting the hierarchy of technologies and products, and the relations between technologies and products. Using our method, these relations can be expanded and customized according to business requirements.

In mobile environment supporting mobility technologies, user requirements have been increased with respect to utilization of location information. In particular, moving object DBMS has consistently posed in order to efficiently maintain traffic information related to location of vehicle which tents to tremendously change over time. Despite the fact that these sorts of researches must be taken into consideration, empirical studies on moving object in terms of map database for lbs service, spatial attribute of which is continuously changed over time, have rarely performed. Therefore, aim of this paper is to suggest efficient spatial index scheme, which is capable of supporting query processing algorithm and location of moving object over time, by developing new empirical model. As a result, we can come to the conclusion that moving object model based on multi-fixed grid index makes it possible to cut down on the number of entity for retrieving. What's more, this model enables hierarchical data to be accessed through efficient spatial filtering on large-scale lbs data and constraints in accordance with level in order to display map.

The record continuum theory is now being studied in Australia, wherein the segregated record management of current, semi-current, and past records based on the temporal flow of the life cycle theory are being critcized. In addition, it emerged as a new paradigm for electronic record management without time and spatial constraints. Moreover, it is recognized as a logical and conceptual entity rather than as a fixed physical object. It also makes it possible to record multiple records in consideration of the complex, multidimensional environment of records. Based on this record continuation theory, the current information and communications technology (ICT) is applied to the four axes and dimension of the record continuation diagram of theoretical researcher Frank Upward. The researchers aim to realize a video recording management method suitable for the electronic record age.
