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.

In this paper, we proposed multimedia based ExamBank system in web environments. In the proposed system the database was designed based on the object-relation model and the application program was implemented with Java such that independent execution would be possible to guarantee no fault for multi-client in Web environments. We defined the Exam entities as objects, and implemented those inter-relationships as user definition and type. In addition, by mapping the schema object of DBMS and JAVA class, it becomes to possible transferring the object systematically between DHMS and JAVA application server.

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.

Relation extraction is to extract relationships between named entities from text. Traditionally, relation extraction methods only extract relations between predetermined subject and object entities. However, in end-to-end relation extraction, all possible relations must be extracted by considering the positions of the subject and object for each pair of entities, and so this method uses time and resources inefficiently. To alleviate this problem, this paper proposes a method that sets directions based on the positions of the subject and object, and extracts relations according to the directions. The proposed method utilizes existing relation extraction data to generate direction labels indicating the direction in which the subject points to the object in the sentence, adds entity position tokens and entity type to sentences to predict the directions using a pre-trained language model (KLUE-RoBERTa-base, RoBERTa-base), and generates representations of subject and object entities through probabilistic crossover operation. Then, we make use of these representations to extract relations. Experimental results show that the proposed model performs about 3 ~ 4%p better than a method for predicting integrated labels. In addition, when learning Korean and English data using the proposed model, the performance was 1.7%p higher in English than in Korean due to the number of data and language disorder and the values of the parameters that produce the best performance were different. By excluding the number of directional cases, the proposed model can reduce the waste of resources in end-to-end relation extraction.

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.
