The KAERI Spent Fuel Remote Technology Development (SFRTD) Department is developing the remote maintenance and repair equipment, which is used in a hot cell in an intense radiation field, as part of a project to develop the Advanced spent fuel Conditioning Process (ACP). Although several mechanical master-slave manipulators (MSMs) is mounted on the hot cell wall, their reach will be limited and cannot access areas for all the ACP equipment maintenance. A Bridge Transported ServoManipulator (BTSM) has been designed to overcome the limitation of access areas that is a drawback of MSMs for the ACP equipment maintenance. The BTSM system consists of four components: a transporter with telescoping tubeset, a slave manipulator, a master manipulator, and a remote control system. The BTSM system has been designed by Solid Edge that is a 3D computer-aided design (CAD) software, except for the remote control system. The master manipulator and the slave manipulator are kinematically similar in design, except for the handle and the tong, respectively. The manipulators have 6 degrees of freedom (DOF) plus the jaws motion. The transporter has traveling, traverse, and hoisting motion to position the slave manipulator.

In metal casting process, it is very difficult to predict the form accuracy of cast part and reduce repeatability error. In this study, the variations of form accuracy were measured in the process of metal cast prototyping, where RP part is manufactured from CAD model in the first, and then, wax part is cast in the vacuum environment using the RP part as master model, and finally metal prototype is cast using ceramic mold and the wax part as pattern. To investigate the variations of form accuracy, the averages and standard deviations of error distribution of the parts measured by 3D scanner were compared. It was observed that the biggest shrinkage is generated during the extraction of wax part in the second step and the biggest deterioration of form accuracy is generated during the metal part casting in the last step.

GIS can be used on almost entire fields of the world, such as the national land management, environmental management, disaster management, enterprise activities, and general lives. GIS is called as an infrastructure of the knowledge information on the cultural society. For insuring the national power on the periods of the unlimited competition, it is very important to establish the national information infrastructure. Purpose of the NGIS project I is to development on living benefits of peoplethrough an efficiency of policy and rationalism of planning. In order to achievement of this purpose, the NGIS project I has been established using the national geographic information base planning. The NGIS project I consists of the master management part, the geographic information part, the technique development part, the standardization part, and the land Information part. These five GIS project parts are operated by four governmental ministers and related institutions, such as minister of transportation and construction, minister of science and technology, minister of information and communication, minister of administrative and home affaires. The NGIS I project is to establishment of the nation spatial information systems, such as various nationwide digital maps, GIS technique development, GIS education, GIS standardization, and GIS researches.

최근 기업의 시스템들은 데이터 공유와 협업을 위해 통합의 필요성을 제기하고 있다. 통합을 위한 방법론으로 서비스 통합을 위한 서비스 지향 아키텍처와 서비스에 사용되는 데이터의 통합을 위한 마스터 데이터가 등장했다. 본 논문은 BP(Business Process)를 효율적으로 운용하기 위한 방안을 제시한다. 우리는 BP를 지원하기 위한 지식 저장소로 XMDR(eXtended Meta Data Registry)과 이를 운용하기 위한 데이터 허브를 구성한다. XMDR은 데이터 통합을 위한 MDM(Master Data Management)을 관리하고, 데이터 간의 이질성을 해결하고, 업무 간의 연관관계를 효율적으로 제공한다. 이것은 MDR(Meta Data Registry), 온톨로지, BR(Business Relations)으로 구성된다. MDR은 구조적 이질성을 해결하기 위한 메타 데이터간의 관계성을 기술한다. 온톨로지는 의미적 이질성과 데이터 간의 관계성을 기술한다. BR은 업무 간의 관계성을 기술한다. XMDR 데이터 허브는 마스터 데이터의 관리를 지원하고, 프로세스 간의 상호작용을 효율적으로 지원할 수 있다.

There are several ways to implement charter parties in the operation of the vessel. Under the time charter party, the charterer borrows the vessel from the shipowner and uses the vessel to benefit his business. The time charter party's legal relationship can be divided into internal and external relationships. This article deals with an internal relationship. The legal matters between the shipowner and charterer are regulated by the agreement. The NYPE is the most widely circulated type of time charter party. According to the NYPE, navigational matters fall upon the shipowner while business matter falls upon the time charterer. There are vague parts in interpreting NYPE articles. NYPE Art. 8, called the employment clause, is one of them. The Master employed by the shipowner should follow the order of the charterer. Whether the charterer has the right to order the Master of the vessel to follow the navigating route recommended by him was addressed in the Hill Harmony case by the UK Supreme Court. The court was affirmative. Under the Ocean Victory case, whether the time charterer has an obligation to order the Master to go out to escape heavy weather from the berth at the port was at issue. The Japanese lower court decided negatively. There is a tendency that many countries insert default rule in the maritime law to apply it to the case at issue in a case where there is no agreement. It serves the enhancement of legal stability; China, Japan, and Germany are such countries. The author thinks that Korea should follow the above three countries' revision of their maritime law.

Abstract: In teleoperation field robotic system such as hydraulically actuated robotic excavator, the maneuverability and convenience is the most important part in the operation of robotic excavator. Particularly the force information is important in dealing with digging and leveling operation in the teleoperated excavator. Excavators are also subject to a wide variation of soil-tool interaction forces. This paper presents a new force reflecting joystick in a velocity-force type bilateral teleoperation system. The master system is electrical joystick and the slave system IS hydraulically actuated cylinder with linear position sensor. Particularly Pneumatic motor is used newly in the master joystick for force reflection and the information of the pressure of salve cylinder is measured and utilized as the force feedback signal. Also force-reflection gain greatly affects the excavation performance of a hydraulically actuated robotic system and it is very difficult to determine it appropriately since slave excavator contacts with various environments such as from soft soil to rock. To overcome this, this paper proposes a force-reflection gain selecting algorithm based on artificial neural network and fuzzy logic.

The development of information technology and the demands of society on an application in an operating system, as well as increasing the specifications and sophistication of smartphones, require banks to make changes to their mobile banking applications. The transformation of the mobile banking application into a digital banking application conducted by banks has made users re-evaluate based on their preferences. This study presents the behavior of users of digital banking applications in Yogyakarta, Indonesia. The hypothesis model is based on Technology Acceptance Model (TAM) with additional factors of the social image, perceived risk and perceived trust adopted from Muñoz-Leiva et al. (2017). The methodology in this study includes data collection through questionnaires distributed online and data analysis using the Structural Equation Model. The results of this study illustrate that the perceived trust and perceived risk have a more dominant part in influencing user attitude and user intention to use digital banking. Meanwhile, social image, perceived ease-of-use and perceived usefulness are not significant in influencing user attitude and user intention to use digital banking. The implication of this research helps to determine the right communication and strategy so that more users with more benefits can utilize this digital banking application.
