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.

본 연구는 압전 작동기 기반 초소형 날갯짓 비행체의 날갯짓 운동을 위해, 압전 작동기의 펌핑 운동을 효과적으로 날갯짓 운동으로 변환하는 힌지 메커니즘 제작 기법에 대해 다루었다. 경량화를 위해 탄소섬유/에폭시(Graphite/Epoxy) 프리프레그를 사용하고, 반복적인 제작이 용이하도록 레이저 절단기를 활용하였으며, 힌지부는 얇은 캡톤 필름을 이용해 컴플라이언트(compliant) 메커니즘으로 구성하였다. 제작된 힌지 메커니즘을 압전 유니모프 작동기 PUMPS에 연결하여 동작시켜 본결과, 300V 170Hz 인가 전압에서 $173^{\circ}$의 큰 날갯짓 각을 가짐을 확인하였다.

현재 국내 게임산업을 최고의 전성기로 이끌고 있는 다중접속역할수행게임(MMORPG)의 패턴 양상을 분석해보면 가상사회에서의 주도적 삶을 함의하고 있는 공간 내러티브의 스토리텔링 방식이 사회성을 지향하고 있다고 정의할 수 있다. 가상사회에서의 삶의 방식을 묘사하는 것은 미디어 간 융합과 연계가 필수적이며, 매우 유동적으로 작동해야 하는데, 이 과정을 구축하는 디자인 공정은 미디어 간 활발한 학문적 기능이 선행되어야 함에도 불구하고 현재까지 디자인 공정의 정량화가 미흡한 실정이다. 아울러 MMORPG 장르의 게임패턴과 MMORPG 장르를 가로지르는 디자인 요소는 최근 국내 온라인게임 산업에 대두되고 있는 위기 스펙트럼과도 밀접한 연관관계를 가지고 있다. 즉 국산 온라인게임 방식에서 고유 특징으로 고착되고 있는 가상사회에서의 삶의 방식에 대한 변별적 방식이 게임디자인 직무에 대한 정립과 적합화 방안을 통해 개선효과가 파급될 수 있음을 제기 하고자 한다.
