In this study, the properties of the object types required to describe the relationship among research data resources, which may be generated during the life cycle of the research, are derived. The properties of Fedora Commons and DSpace, which are open source software used for resource management, and schema properties published in DataCite were analyzed. Based on relation names of Fedora Commons, nine new relation names were derived. Thirty-eight object type properties consolidating the target properties of the analysis were derived. The result of this study can be used as basic material for crosswalk research studies of object type relation terms to ensure interoperability among the systems.

본 논문에서는 웹 상에서 멀티미디어를 기반으로 한 문제은행 시스템을 제안하였다. 제안된 문제 은행 시스템은 객체-관계(Object-Relation)형 모델로 데이터베이스를 설계하고, 웹 환경에서 다수 클라이언트에 대한 무결성을 위해 독립적 실행이 되도록 Java 언어로 응용프로그램을 구현하였다. 문제 엔티티들은 객체로 정의하고, 이들간의 관계를 사용자 정의유형과 타입으로 설계 구현하였으며, DBMS의 스키마 객체와 JAVA Class를 매핑하여 DBMS와 어플리케이션 서버간에 체계화된 동작으로 객체를 전달할 수 있도록 하였다.

This paper presents a new approach of recognizing a 3D object using a single camera, based on the extended convex hull of its silhouette. It aims at minimizing the DB size and simplifying the processes for matching and feature extraction. For this purpose, two concepts are introduced: extended convex hull and measurable region. Extended convex hull consists of convex curved edges as well as convex polygons. Measurable region is the cluster of the viewing vectors of a camera represented as the points on the orientation sphere from which a specific set of surfaces can be measured. A measurable region is represented by the extended convex hull of the silhouette which can be obtained by viewing the object from the center of the measurable region. Each silhouette is represented by a relation graph where a node describes an edge using its type, length, reality, and components. Experimental results are included to show that the proposed algorithm works efficiently even when the objects are overlapped and partially occluded. The time complexity for searching the object model in the database is O(N) where N is the number of silhouette models.

최근 전자 태그를 이용한 응용 서비스가 활성화됨에 따라 전자 태그의 데이터 처리에 대한 연구가 광범위하게 진행되고 있다. 따라서, 다양한 전자 태그로부터 수집된 객체 정보를 효율적으로 처리하기 위해 웹상에서 널리 사용되고 있는 XML 기반의 데이터 처리를 요구하고 있다. 이를 위해 EPCIS(EPC Information Service)는 EPC 관련 데이터를 공유하기 위한 표준인터페이스를 정의하였다. 현재 EPCIS 1.0 스펙의 Core Event Type은 EPC 네트워크에서 필요한 핵심타입들만을 정의하였고 적용 분야에 따른 비즈니스 context와 관련된 타입들은 정의하고 있지 않다. EPC 네트워크를 특정 비즈니스 영역에 적용할 때, Core Event Type 외에 추가적으로 정의해야 할 정보에 대한 타입 이 필요하다. 이에 본 논문에서는 이러한 비즈니스 영역에서 자주 사용되는 재사용 가능한 객체 타입을 정의하고 있다. 이렇게 정의한 객체타입과 EPCIS Spec에서 정의한 Core Event Type을 활용하여 해운 물류분야의 객체 정보 데이터 모델에 따른 스키마를 설계하였다.

관계 추출은 텍스트로부터 개체(named entity) 사이의 관계를 추출하는 과정이다. 전통적으로 관계 추출 방법은 주어와 목적어가 미리 정해진 상태에서 관계만 추출한다. 그러나 종단형 관계 추출에서는 개체 쌍마다 주어와 목적어의 위치를 고려하여 가능한 모든 관계를 추출해야 하므로 이 방법은 시간과 자원을 비효율적으로 사용한다. 본 논문에서는 이러한 문제를 완화하기 위해 문장에서 주어와 목적어의 위치에 따른 방향을 설정하고, 정해진 방향에 따라 관계를 추출하는 방법을 제안한다. 제안하는 방법은 기존의 관계 추출 데이터를 활용하여 문장에서 주어가 목적어를 가리키는 방향을 나타내는 방향 표지를 새롭게 생성하고, 개체 위치 토큰과 개체 유형 정보를 문장에 추가하는 작업을 통해 사전학습 언어모델 (KLUE-RoBERTa-base, RoBERTa-base)을 이용하여 방향을 예측한다. 그리고 확률적 교차 연산을 통해 주어와 목적어 개체의 표상을 생성한다. 이후 이러한 개체의 표상을 활용하여 관계를 추출한다. 실험 결과를 통해, 제안 모델이 하나로 통합된 라벨을 예측하는 것보다 3 ~ 4%p 정도 더 우수한 성능을 보여주었다. 또한, 제안 모델을 이용해 한국어 데이터와 영어 데이터를 학습할 때, 데이터 수와 언어적 차이로 인해 한국어보다 영어에서 1.7%p 정도 더 높은 성능을 보여주었고, 최상의 성능을 내는 매개변수의 값이 다르게 나타나는 부분도 관찰할 수 있었다. 제안 모델은 방향에 따른 경우의 수를 제외함으로써 종단형 관계 추출에서 자원의 낭비를 줄일 수 있다.

A Typically-Perceived-Situation(TPS) is a situation which might be useful for conceptual learning of science, rising spontaneously in an individual's mind when someone is thinking about, or in relation to, any object such as physical object, concept, situation, etc. But, for a discussion about the TPS' usefulness in depth, we need to analyze the specific features of the TPS in relation to conceptual learning of science. This study investigated four elementary school students' TPSs related to the topic of the action of force, especially (a) 'the situation where force is being acted on an object', and (b) 'the situation where force is not being acted on an object', with an interview as well as with a drawing-and-explanation type questionnaire. Their TPSs were then compared with their concepts, checked by a misconception questionnaire of choice-and-explanation type. The results showed that the students' TPSs illustrated not only their conceptions about the action of force, but also gave more fruitful details of their ideas, including (a) clues of their conceptions, (b) concrete situations, and (c) their past experiences with emotional components. On the whole, the TPS's appeared to be rather stable, affected by their past experiences, and needed to be analyzed into their sub-units for more subtle details. Finally, some practical ways of how to apply the ideas of the TPS to the conceptual learning of science are suggested.

Especially, the case which the facilities have been shielded in the building. In this case there must be suitable grounding system, and this case must be considered sufficiently to the one part of the design at the design. in addition there must be an electric leakage defense system and The case to be a criterion signal ground system. Rod type grounding electrodes is applied much and we studied the relation that rod type grounding method and shielding room as newly grounding object. in this paper, shield room is the object(target) to be established newly additionally, we try to describe about the flow of a grounding technology concept change and a ground facilities.

Narcissism is a pathological phenomenon and narcissistic subject always needs to put itself on the top and has interest in nothing but its own determination. The protagonist of Adversary by ?mmanuel Carr?re does pay careful attention to what others are thinking of him while he does not distinguish difference between object of love and himself. So he can be allegedly narcissistic subject. And it can be said that the behaviors of Mary in the movie Under the sand by Ozon are included in narcissism in that narcissistic subject has the characteristics that idealizes the object of libido. However, in this study, the heroine is examined based on such a point that the object of love and extreme idealization incline toward others. We call this case reverse-narcissism. In Part 2, it is investigated what relation narcissism as an unconscious psychological tool has with Oedipus complex, which plays an important role in forming human psyche. For instance, disappointment caused by prohibition at the oedipal stage is too severe, which creates superego and its idealization to protect in such a way that narcissistic regression can not be done. Cases of extremely big gap between ego and ideal type are perversion, impostor, mania, paranoia, etc, where narcissistic and oedipal elements are combined to affect.

A master-slave system is proposed as a teaching device for a dual arm robot. The slave robots are remotely controlled by two delta-type master arms. In order to help the operator to observe the target object from the desired position and desired direction, cameras are mounted on a specialized manipulator, Movements of two slave arms are coordinated with that of the cameras. Due to this coordinated movements, the operator needs not to care the geometrical relation between the cameras and the slave robots.

The multiple cooperating robot system plays an important role in the research of modern manufacturing system as the emphasis of production automation is more on the side of flexibility than before. While the kinematic and dynamic analysis of a single robot is performed as an open-loop chain, the dynamic formulation of robot in a multiple cooperating robot system differs from that of a single robot when the multiple cooperating robots form a closed kinematic chain holding an object simultaneously. The object may be any type from a rigid body to a multi-joint linkage. The mobility of the system depends on the kinematic configuration of the closed kinematic chain formed by robots and object, which also decides the number of independent input parameters. Since the mobility is not the same as the number of robot joints, proper constraint condition is sought. The constraints may be such that : the number of active robot joints is kept the same as mobility, all robot joints are active and have interrelations between each joint forces/torques, two robots have master-slave relation, or so on. The dynamic formulation of system is obtained. The formulation is based on recursive dual-number screw-calculus Newton-Eulerian approach which has been used for single robot analysis. This new scheme is recursive and compact symbolically and may facilitate the consideration of the object in real time.
