Beneficiary must present all documents stipulated in the Credit. If the documents conform in all respects with the terms and conditions of the Credit, beneficiary has a right to payment from an issuing or confirming bank. And banks must examine all documents presented by beneficiary for taking up the documents. If the documents appear on their face not to be in compliance with the terms and conditions of the Credit, banks may refuse to take up the documents. But standard for compliant documents with the terms and conditions of the Credit in the UCP or Section 5 of UCC is unclear. Because UCP Article 13(a) provides merely that banks must examine all documents stipulated in the Credit ${\cdots}$ to ascertain whether or not they appear, on their face, to be compliance with the terms and conditions of the Credit. ${\cdots}$ Documents which appear on their face to be inconsistent with one another will be considered as not appearing on their face to be in compliance with the terms and conditions of the Credit. Also UCC Section 5-108(a) provides merely that. ${\cdots}$ an issuer shall honor a presentation that, ${\cdots}$ appears on its face strictly to comply with the terms and conditions of the letter of credit. All problems are not resolve with easy by these regulations. Accordingly, I examined requirements for compliant documents with the terms and conditions of the Credit on the basis of the UCP and cases. To analyse this, I divided into three requirements ; (1) Completeness, (2) Regularity, (3) Linkage.

Unlike industrial manipulators, the manipulators mounted on the service robots are interacting with humans in various aspects. Therefore, safety has been the important design issue. Many compliant robot arm designs have been introduced for safety. It is known that passive compliance method has faster response and higher reliability than active ones. In this paper, a new safe mechanism based on passive compliance has been proposed. Passive mechanical elements, specifically transmission angle of the 4-bar linkage, springs and shock absorbing modules are incorporated into this safe mechanism. This mechanism works only when the robot arm exerts contact force much more than the human pain tolerance. Validity of the safe mechanism is verified by simulations and experiments. In this research, it is shown that the manipulator using this mechanism provides higher performance and safety than those using other passive compliance mechanisms.

Various jumping robot platforms have been developed to carry out missions such as rescues, explorations, or inspections of dangerous environments. We suggested a jumping robot platform using energy conversion of the elastic body like the bar of a pole vault, which is the main part in which elastic force occurs. The compliant link was optimized by an optimization method based on Taguchi methodology, and the robot's leaping ability was improved. Among the parameters, the length, width, and thickness of the link were selected as design variables first while the others were fixed. The level of the design variables was settled, and an orthogonal array about its combination was made. In the experiment, dynamic simulations were conducted using the DAFUL program, and response table and sensitivity analyses were performed. We found optimized values through a level average analysis and sensitivity analysis. As a result, the maximum leaping height of the optimized robot increased by more than 6.2% compared to the initial one, and these data will be used to design a new robot.

As the technology of Smart City and Digital Twin is developing, techniques to integrate BIM data of infrastructure facilities into GIS are becoming more critical. Hence, this study aims to manage BIM data representing bridge and tunnel structures through the Industry Foundation Classes (IFC) standard and to develop a method to link these IFC-compliant files to the GIS standard CityGML without loss of information. We analyze the criteria for creating BIM data for bridges and tunnels by reviewing the BIM guidelines set by each client. We use these criteria to suggest methods for data management based on InfraBIM as a specific IFC class standard. Furthermore, we perform model analysis to determine the necessary design and construction field-appropriate model process and Level of Detail (LOD). From the model analysis, we conclude that the classified BIM models can be used as base data to generate BIM models of bridges and tunnels for facility management.

This paper deals with a fabrication method of composite hinge mechanisms for flapping-wing micro air vehicles. The fabrication process includes curing process of Graphite/Epoxyprepregs, laser cutting for high fabrication repeatability, laminating of Graphite/Epoxy prepregs with Kapton film which is used for flexure, and so on. The fabricated hinge mechanism was attached with PUMPS actuators and the measured flapping angle was $173^{\circ}$ when driving voltage was 300V 170Hz.

Analyzing the aspects of pattern in MMORPG that has been leading our domestic game industry to the climax, our game industry might be thought to orient the space narrative storytelling method containing the leading life in the virtual sociality to the nature of society. It is essential to have the convergence and linkage between media in describing the lifestyle in the virtual society, which should be operated in a very flexible manner. It is, however, true that we are lacking of the quantification of designing process until now, although the designing process should have the vivid academic functions between media in advance. In addition, the designing crossing over the MMORPG genre along with the game patterns in the MMORPG genre has close correlations with the spectrum of crises emerging recently in our domestic online game industry. In other words, this essay aims at raising an issue that the selective method to the lifestyle in the virtual society being settled down as characteristics inherent to the methods of our domestic online games might deliver the improving effects through the establishment of game designing jobs and compliant plans.
