스쿠버 무감압한계 잠수환경에서의 반복 잠수 활동이 인체의 생리적 반응과 스트레스 호르몬에 미치는 영향을 알아보기 위하여 동일 장소와 수온 그리고 수심에서 잠수경력이 비슷한 다이버 8명을 대상으로 반복 잠수를 실시하였다. 잠수 전, 첫 잠수 후, 반복 잠수 후 개별 측정 및 채혈한 결과 생리적 반응은 심박수, 체온, 수축기 혈압이 잠수 전과 첫 잠수 후, 반복 잠수 후 간의 유의한 차이가 있었고 이완기 혈압은 잠수 전과 첫 잠수 후에는 증가하였으나 반복 잠수 후에는 다시 감소하여 유의한 차이가 없었다. 스트레스 호르몬 변화에서는 잠수 전, 첫 잠수 후, 반복 잠수 후의 유의한 차이가 없었다. 스포츠 스쿠버 잠수표 계획에 따른 무감압 한계 반복 잠수 활동은 심박수, 체온, 수축기혈압을 감소시키는 반면 스트레스 호르몬에는 영향을 미치지 않는 것으로 나타났다. 안전한 다이빙을 위해서는 보다 많은 생리학적 연구가 필요하다고 생각된다.

Eteching characteristics of the Indium Tin Oxide (ITO), which is transparent conductor, was investigated with CH4/H2 and Ar as etching gases for the Reactive Ion Etching (RIE). With CH4/H2 for the etching gas, the highly selective etching characteristics for the ITO on GaAs was obtained. It was examined that the dominant etching parameter for the selective etchning of ITO on GaAs structure was the chamber pressure. But, the etching selectivity for ITO on InP was poor eventhough we tried systematic etching. RIE etching conditins using CH4/H2 gas was limited due to the formation of polymer on the substrates. In the case of Ar gas for the reactive gas, the selectivity of ITO on BaTiO3 was above 10. The etch rete of ITO was more sensitive to the etching parameters than that of BaTiO3, which was almost constant with different etching parameters.

Objective: This paper aims to discuss the case study of Design Dive: Service Design Workshop that was held to improve public services by applying service design methods(February 2011~May 2011). In so doing, it suggests the ways in which public services can be innovated from a design-oriented perspective. Background: As citizens' social and cultural awareness of services is enhanced, there have been emerging needs for innovation of public services. Accordingly, the methods of service design which is to design holistically users' experiences have been considered as an important means to innovate public services. Method: In this regard, the present paper introduces and explores the example of the Design Dive Workshop as a platform whereby service design is achieved. In particular, it analyzes the results of the workshop. Results: The paper presents the results of the workshop and the 10 possible scenarios of public services that were explored in the workshop and suggests models for empowering the workshop participants. Conclusion: Service design is a very effective methodology for providing a new perspective on user-oriented design of public services. The workshop had educational effects on enhancing the participants' awareness of the role of public service design. Application: The Design Dive workshop contributed to improving public services and achieved positive educational results. The methods developed in the workshop can effectively be applied to various occasions on which public services should be improved.

본 논문에서는 XNA Framework 기반의 모바일 게임 Dragon Dive를 설계하고 구현한다. 이 모바일 게임은 종 스크롤 형식의 탄막 슈팅 게임의 방식을 채택하고 있으며 100초 동안 최대 점수를 획득하는 게임이다. 플레이어는 정해진 시간동안 화면 위에서 내려오는 3종류의 몬스터를 제거하고, 제거한 몬스터의 수에 따라 Dragon 캐릭터의 모양과 미사일의 연사 속도가 증가한다. 그리고 제거하지 못한 몬스터가 10마리이상 되면 게임이 종료된다.

In this paper a typical problem is examined that a light, general aviation airplane, such as Cessna or Navion, in gliding turn flight shows helical-dive phenomenon when pilots try to stop the descent by using elevator only. It is known from pilot's experience that in a certain flight trim it is impossible to recover from helical-dive by using elevator only. From this study it is shown that helical-dive phenomenon is involved with longitudinal/lateral dynamics coupling to airplane's aerodynamics. Also this phenomenon consists of three parts of flight dynamics; first of all, fast longitudinal motion occurs, then is followed by a little slow lateral motion, and finally logitudinal/lateral coupled motion is fully developed.

This paper deals with the development of an expert system modeling by constructing a knowledge-based system of the dive recovery for anticrash on the ground or sea during the task of fighter aircraft. In an IBM PC / XT computer, a prototype dive recovery expert system is constructed using mu LISP-86 programming language, and is interconnected to the SAM SUNG RM-501 robot arm to test and simulate this model. The knowledge base of this model is composed of the dive recovery charts and the V-N envelope charts of F-4 D Phantom fighter aircraft. It is shown that the prototype expert system woks well and the feasibility of practical realization is valid.
