A posteriori physicalists criticize non-physicalist arguments based on the framework of two-dimensional semantics. Most of them argue for physicalism based on the analogy between scientific identity statements and psychophysical identity statements. This paper argues for another version of aposteriori physicalism, so called physicalism employing 'phenomenal concept strategy' or 'exceptionalist strategy', which appeals to merely the nature of phenomenal concept without recourse to a semantic framework. Loar's phenomenal concept strategy employs the aspect of our recognitional ability of objects in criticizing non-physicalism, leading to the argument that phenomenal concepts are 'exceptional' in applying conceivability-possibility link. I critically examine Stoljar's, Chalmers', Raffman's criticisms against Loar's exceptionalists strategy. Loar's phenomenal concept strategy reflects well our psychological aspects surrounding the acquisition and the possession of 'phenomenal concept'. In several respects, Loar's exceptionalist version of a posteriori physicalism is the best explanation for accounting for both the explanatory gap and the a posteriority of psychophysical identity.

미디어 파사드의 개념 및 종류, 역할에 대해서 알아보았고, 미디어 파사드가 앞으로 나아갈 방향에 대해서 논의해보았다. 미디어 파사드는 디지털 기술의 발전과 융합되어 다양한 분야에서 활용되어지고 있고, 예술의 콘텐츠를 보여주던 미디어 아트의 성격을 토대로 다양한 목적에 맞춰 미디어 콘텐츠를 효과적으로 관람자에게 전달할 수 있다. 건축물에 영상을 상영함으로써 외향적으로는 도시의 미관 및 랜드마크 효과를 담당하며 내재적으로는 도시의 독자성(identity) 및 브랜드(brand)를 보여줄 수 있다. 미디어 파사드는 인터랙션이 가능한 방향으로 진화하여 시민과의 상호작용, 즉 소통(communication)을 강화한 시민 중심(citizen-centered)의 미디어 문화로 발전해야 한다.

임베디드 리눅스의 개발은 커널과 각 시스템 응용들을 자신이 원하는 플랫폼에 맞추어 일일이 수작업으로 설정, 컴파일, 타겟에의 인스톨 과정을 거쳐야 한다. 이것은 실제 타겟에 필요한 응용 개발에 앞서 많은 개발 시간을 소요하게 하며, 또한 그 과정 중 많은 시행착오의 반복을 야기하게 한다. Qplus 타겟 빌더는 임베디드 리눅스 개발 과정 중 설정 가능한 사항들을 옵션화하여 개발자가 통합된 환경에서 커널과 응용을 세세하게 설정할 수 있게 하며, 각 옵션들간의 의존성을 자동으로 검사함으로써 타겟에 적합한 설정을 할 수 있게 도와준다. 또한 타겟에 적재(deployment)될 수 있는 형태로 루트파일 시스템을 자동 생성하고 라이브러리 최적화를 통해 사이즈를 최적화시킨다. Qplus 타겟빌더는 인터렉티브한 타겟 시스템 설정과 자동화된 타겟에의 적재로 임베디드 리눅스의 개발 시간을 단축시켜 준다.

This study is to clarify the true meaning of christian ceremonial dress, based on the Biblical background, by examining the origin and the symbolic meaning of the Catholic ceremonial dress. The influence of the Liturgical movement on the ceremonial dress and the changes in the symbolic meaning of the Christian ceremonial dress are studied. This research also aims to closely examine the difference in Christians' consciousness on the Christian ceremonial dress such as gown, stole, and clergy shirt. It aims to provide basic resources for the education and further study on the Christian ceremonial dress through reconfirming the basic understanding and the symbolic meaning of the Christian ceremonial dress. As a result, according to the lesson of the Bible and the ideology of the Reformation, it is suggested that priests should wear regular suits or the traditional Hanbok rather than wearing gown or Roman collar. However, if most of Christians believe that it is critical to wear ceremonial dress to project holiness and seriousness during the service, it is suggested that priest should wear gown only and avoid Roman collar and stole because they only show the hierarchy of priests. Accordingly, there is a hope in this research that the knowledge of ceremonial dress could be re-defined based on the Evangelism in the Bible though the results of the study.

기존 안드로이드 응용프로그램에 대한 자원 접근 제어는 응용프로그램을 작성한 개발자가 XML 파일에 미리 선언한 권한을 검사하는 방식으로 이루어진다. 이 권한은 인스톨되는 시점에 사용자의 동의를 얻어 해당 응용프로그램에 수여되며 응용프로그램이 특정 권한을 의도적으로 사용자로부터 은닉하는 것을 방지할 수 있다. 하지만 사용자는 해당 응용프로그램에 허용하고자 하는 일부 권한만을 수여할 선택권이 없다. 선언된 모든 권한을 허락하거나 그렇지 않으면 아예 응용프로그램을 설치할 수 없게 된다. 또한, 응용프로그램에 부여한 권한을 변경할 수는 없고 박탈하는 방법은 응용프로그램을 삭제하는 방법밖에 없었다. 따라서 본 논문에서 제안하는 기법은 응용프로그램의 자원 접근을 사용자가 fine-grained 하게 제어할 수 있도록 하는 기법이다. 이를 위해 응용프로그램을 사용하는 시점에도 각 접근 권한을 '항상 허용', '항상 사용자가 확인' 그리고 '항상 거부'로 세부적으로 설정 및 변경이 가능하도록 하였다. 또한, MS Windows Vista 에서 적용하고 있는 '사용자계정컨트롤'(User Account Control)과 같이 응용프로그램이 요구하는 권한 중 '항상 사용자가 확인'으로 설정 된 권한은 요청 시점에 사용자에게 팝업을 띄워 접근 제어에 대한 가시성을 확보하여 사용자가 확인할 수 있도록 하였고 사용자가 이를 수락한 경우에만 해당 권한을 수여 받을 수 있도록 하였다.

Software streaming allows the execution of stream-enabled software on desktop or portable computing devices like PC, PDA, laptop, cellular phone, etc., even while the transmission/streaming from the server may still be in progress. In this paper, we present an efficient streaming system called Software On-Demand(SOD) streaming system to transmit stream-enabled applications in addition to automatic installation of program registry, environment variables, configuration files, and related components. In particular, we design and implement a SOD system in Linux to provide the user with the instant look-and-click software execution environment such that software download and installation are internally proceeded in a completely user-transparent way. Therefore, the SOD system relieves the user from the tricky, failure-prone installation business. In addition, the software developer now obtains a new, powerful means to advertise and propagate their software products since the user can use software packages via user-friendly UI window or web browser by look-and-click interactive operation. In the paper, we also make a couple of SOD streaming experiments using a spectrum of popular softwares. Based on the analysis of the experiment results, we also propose two performance improvement schemes.

There is a growing interest this paper for ocean sensing where autonomous vehicles can play an essential role in assisting engineers, researchers, and scientists with environmental monitoring and collecting oceanographic data. This study was conducted to develop a rigid sail for the autonomous sailing drone. Our study aims to numerically analyze the aerodynamic characteristics of curvy twin sail and compare it with wing sail. Because racing regulations limit the sail shape, only the two-dimensional geometry (2D) was open for an optimization. Therefore, the first objective was to identify the aerodynamic performance of such curvy twin sails. The secondary objective was to estimate the effect of the sail's spacing and shapes. A viscous Navier-Stokes flow solver was used for the numerical aerodynamic analysis. The 2D aerodynamic investigation is a preliminary evaluation. The results indicated that the curvy twin sail designs have improved lift, drag, and driving force coefficient compared to the wing sails. The spacing between the port and starboard sails of curvy twin sail was an important parameter. The spacing is 0.035 L, 0.07 L, and 0.14 L shows the lift coefficient reduction because of dramatically stall effect, while flow separation is improved with spacing is 0.21 L, 0.28 L, and 0.35 L. Significantly, the spacing 0.28 L shows the maximum high pressure at the lower area and the small low pressure area at leading edges. Therefore, the highest lift was generated.

The MOCT(Ministry of Construction & Transportation) gave a order named as "The guideline for computerization and application of geotechnical investigation result" to an affiliated organization in March 2007. Today, pilot project of construction of geotechnical information database is in process to be stable for its system after applying this guideline, and discipline how to input investigated data for related users. We have developed standard for geotechnical investigation result-format, metadata for distribution of geotechnical information and to coordinate based on world geodetic system. Also, We had a introduce to status with respect to use the input system, collect a statistics of input contents. At a result, improvement items of input system is proposed. It was analyzed that most users put to practical use easily as a result of education for making use of on the spot of the developed GIIS. But There were problems with the GIIS as well as complexity of metadata formation, such as error of moving part of information window, and a part of recognition error of install program in accordance with computer OS circumstances. Particularly, to improve some parts of GIIS is needed, because of use of or KNHC (Korea National Housing Corporation)-specific format and difference of input process followed by MOCT's guideline. In this study, it is planning to make up for occurred problems, and improvements when operating and managing the Geotechnical Information DB center in 2008.
