In highly informative, perception-rich environments that we call Omniscient Spaces, robots interact with physical objects which in turn afford robots the information showing how the objects should be manipulated. Object manipulation is commonly believed one of the most basic tasks in robot applications. However, no approaches including visual servoing seem satisfactory in unstructured environments such as our everyday life. Thus, in Omniscient Spaces, the features of the environments embed themselves in every entity, allowing robots to easily identify and manipulate unknown objects. To achieve this end, we propose a new paradigm of the interaction through Radio Frequency Identification (RFID). The aim of this paper is to learn about RFID and investigate how it works in object manipulation. Specifically, as an innovative trial for autonomous, real-time manipulation, a likely mobile robot equipped with an RFID system is developed. Details on the experiments are described together with some preliminary results.

In this study, a translator for transferring structural analysis data among commercial structural analysis programs was developed. The translator adopted the neutral format type based on ISO standard STEP AP 209 not only for the international standardization and robustness but also for the efficient management of structural analysis data Additional load entity is developed and added to AP 209 for the prevention of loss of information in retrieving exact loading condition. A modulization which is needed for efficient management and extension of the translator was made for the encapsulation of file format of each commercial code. Pilot tests peformed with 3-D frame analysis data of Sung-su bridge show that the developed translator guarantees the integrated management of analysis information as well as the exact transferring and retrieving of analysis data and related information.

Every mechanical part is fabricated with the variations in its size and shape, and the allowable range of the variation is specified by the tolerance in the design stage. Geometric tolerances specify the size or the thickness of each shape entity itself or its relative position and orientation with respect to datums while considering their order of precedence. It would be desirable if the assemblability of parts could be verified in the computer when the tolerances on the parts are store together with the geometric model of the parts of an assembly and their assembled state. Therefore, a new method is proposed to represent geometric tolerances and to determine the assemblability. This method determines the assemblability by subdividing the ranges of relative motion between parts until there exists the subdivided regions that do not cause the interference.

With the advent of the Free Trade Agreement between Korea and the U.S. and an increase in trade volume between the two countries, the possibility of commercial disputes has escalated among international merchants. It has been well-known that arbitration as an alternative dispute resolution is an efficient way to resolve international commercial disputes. When arbitral awards are enforced in the judicial system, the court will inevitably have to be involved with the enforcement procedures. The court is a typical legal entity to confirm arbitral awards. Through a confirmation process, the winning party obtains the same legal status of final judgment rendered by the court. However, a winning party in arbitration will have to overcome a legal hurdle in the enforcement process of arbitral awards. This article aims to investigate how the courts control the arbitration practices and what the basic legal issues in the enforcement of arbitral awards are. The US Federal Arbitration Act is investigated, while relevant cases are reviewed and updated for legal analysis.

Malignant gastrointestinal neuroectodermal tumor (GNET) is a very rare disease entity, especially in the esophagus. The diagnosis of GNET is based on histologic, immunohistochemical, and genetic findings. The choice of treatment is complete resection, and further treatment options can be considered. H erein, we describe a case of successful surgical treatment of a 23-year-old man with recurrent malignant esophageal GNET.

World Trade Organization(WTO) has 164 members since it has established on 1995. It plays a significant role in solving the world trade disputes. The process of the dispute settlement mechanism includes five steps: Negotiation, Establishment of experts group, Deliberation of appellate body, Execution and Supervision of Verdict and the Sanctions for Default. It suggested that the higher rate of developed countries using mechanism to solving the disputes than developing countries solving disputes by mechanism through the analysis of dispute of WTO members. Meanwhile, the more powerful economic entity is, the more trade dispute will be. There are several problems of mechanism by analysis the recently famous cases of trade disputes: Overburden of experts panel, Low utilization rate of the mechanism of developing countries, Lack of economic competition policy and labor standard terms and Unfulfillment of retaliatory measures of developing countries towards developed countries. This paper propose proper solutions and advises to improve mechanism of WTO dispute settlement.

Recent scandals of milk additives in several developing countries provoked controversy about quality issue of dairy products, grapping academic attention to the dairy supply chain. In this paper, we first focus on moral hazard problem of self-interested entities about the quality across the dairy supply chain, due to unobservable and unverifiable quality management efforts of all entities - including dairy producers, stations, and a final producer - and high inspection cost for the quality. Based on the identified moral hazard problem, we understand why the adoption of IoT-based tracking systems about quality produced from each entity is a must, different from RFID-based tracking systems.

In the course of survey of marine algal flora in Korea, a red algal species was collected from Pohang located in the eastern coast of Korea. This shares features of Hypnea, and is characterized by more or less percurrent axis and numerous and short branchlets densely covering axis and branches with basal constrictions, and absence of lenticular thickenings in medullary cell walls. In a phylogenetic tree based on rbcL sequences, this species nests in the same clade as Hypnea esperi. Genetic distance between this Korean entity and H. esperi was in intraspecific range as 0.6%. This alga is identified as Hypnea esperi based on the morphological and molecular data. This is the first record of H. esperi in Korea.

개체명 인식은 입력 문장에서 인명, 지명, 기관명, 날짜, 시간 등과 같은 고유한 의미를 갖는 단어 열을 찾아 범주를 부착하는 기술이다. 기존의 연구에서는 단어 단위나 음절 단위를 입력으로 사용하였다. 하지만 단어 단위의 경우 미등록어 처리가 어려우며 음절 단위의 경우 단어 고유의 의미가 희석되는 문제가 발생한다. 이러한 문제들을 해결하기 위해 본 논문에서는 형태소 단위 개체명 인식기와 음절 단위 개체명 인식기를 앙상블하여 보정된 결과를 예측하는 개체명 인식기를 제안한다. 제안된 모델은 각각의 단일 입력 모델보다 향상된 F1-점수(0.8049)를 보였다.
