In order to utilize a municipal waste incinerated bottom ash and recycled coarse aggregate as the concrete fine aggregate and the coarse aggregate respectively, this study was intended to find out proper alternation ratio through comparing and considering the features of concrete specimens with different alternation ratio, and to evaluate applicability through producing the concrete prototype. The results are followed. 1) As the result of measuring a compressive strength, when the alteration ratio of incinerated bottom ash and recycled coarse aggregate was increased, the compressive strength was decreased. Such tendency was bigger in the incinerated bottom ash. 2) The concrete compressive strength with 0~50% alteration ratio of incinerated bottom ash and 0~75% alteration ratio of recycled coarse aggregate satisfied the design strength. 3) When the incinerated bottom ash and recycled coarse aggregate was alternated, the flexible strength was lower than non-alteration case. It was indicated that this satisfied the flexible strength standard required for a paving block. Hence, it could be applicable for the concrete product. 4) As the result of measuring a change of drying shrinkage length, when the alteration ratio of incinerated bottom ash and recycled coarse aggregate was increased, the drying shrinkage length was increased. But, when the alteration ratio of incinerated bottom ash and recycled coarse aggregate was 0~50% respectively, it satisfied the range of drying shrinkage length change of general concrete. 5) As the result of comparing and considering each specimen’s characteristics in this study, the proper alteration ratio of incinerated bottom ash and recycled coarse aggregate was determined as about 50% respectively. 6) The compressive strength of concrete prototype (PYeongYi Pile) produced by applying the proper alteration ratio of incinerated bottom ash and recycled coarse aggregate satisfied the standard strength.

위성 DMB 휴대단말기용 마이크로스트립 원형편파 안테나 설계 및 제작 오늘날 기술 발전에 의한 디지털화 추세는 방송과 통신으로 분리되어 있던 기존 사업 영역의 융합을 촉진하는 결과를 가져온다. 컴퓨터, 방송, 통신간의 상호 결합이 진행됨에 따라 서로 다른 분야로 고정되어 각각의 영역이 엄격하게 구분되어 있던 개별 미디어의 독자성과 독립성이 약화되는 동시에 서로 다른 미디어간의 결합과 융합이 가속화되고 있다. 이러한 디지털 컨버전스(Digital convergence)에 의해 방송과 통신의 융합 서비스 형태인 위성 DMB(Digital Multimedia Broadcasting)가 우리나라에서 2005년 상용화 되었다. 위성 DMB(Digital Multimedia Broadcasting)는 위성 방송을 통해 방송 콘텐츠를 송출하여 가입자들이 실내외 또는 이동 중에 개인 휴대용이나 차량용 수신기를 통해 비디오, 오디오 및 데이터 등 다양한 멀티미디어 방송을 다채널로 시청하거나 청취할 수 있는 방송 서비스를 말한다. 이 서비스는 종전의 아날로그 방송 형태를 디지털화 함으로써 고품질 CD 수준의 음질, 다양한 데이터 서비스, 우수한 이동수신 품질 등을 제공하게 되고 기존의 단방향성 방송 개념을 양방향성 방송으로 확장시켰으며, 데이터 방송을 통해 음악방송 외에도 뉴스, 교통정보, 기상정보, 지리위치정보, 스포츠, 영화 등 다양한 멀티미디어 정보를 전송할 수 있게 되었다. 휴대용 위성 DMB 시스템과 같은 이동무선통신 시스템의 소형화를 위해 안테나의 소형화 요구가 더욱 커지고 있지만 그 크기가 파장에 기인되는 특성으로 소형화에 대한 어려움이 있다. 이러한 점을 극복하이 위해 안테나에 사용되는 유전체의 비유전율을 높게 하여 소형화를 시키는데, 이러한 경우 유전손실로 인한 대역폭 감소 및 방사효율 저하 등 안테나의 성능이 저하되는 한계가 있기 때문에 패치 구조의 변형을 통한 소형화의 연구가 필요하다. 따라서 위성 DMB 수신 단말기용 안테나에 낮은 비유전율을 갖는 유전체를 사용하고 대역폭 확보 및 성능 향상을 위한 안테나 소형화가 요구되며, 특히 수신 단말기의 자세에 무관하게 전방향에서의 수신이 가능한 무지향성 방사패턴의 안테나의 제작이 요구된다. 본 논문에서는 위성 DMB 마이크로 스트립 안테나를 설계 및 제작하고 이 특성을 바탕으로 단말기에 응용한 안테나를 설계하고 제작한다. 우선 제2장에서 안테나의 원리를 설명하고 제3장에서는 마이크로 스트립 안테나의 기본 이론과 위성 DMB 대역의 마이크로 스트립 안테나를 설계하고 시뮬레이션 특성을 기술하였다. 그리고 제4장에서 마이크로 스트립 안테나를 이용하여 단말기에 이용될 수 있게 안테나를 설계하고 시뮬레이션 특성을 기술하였다. 제5장에서는 시뮬레이션을 바탕으로 실제 제작된 안테나의 성능을 측정하였다. 마지막으로 제6장 결론에서는 제작된 안테나의 고찰과 향후과제에 대해서 살펴보겠다. Design and Fabrication of Microstrip Circular Polarization Antenna for the Satellite DMB Mobile Application Satellite DMB in Korea mainly focuses on mobile TV service and its reception in harsh conditions such as in-building out of satellite line of sight(LOS), underground and in a region shaded by high buildings. This means that a repeater system(gap-filler) is required to receive signals in such an environment. An antenna for this repeater system must have enough isolation to reduce interference between systems, and high gain. In this paper, we propose a microstrip antenna with sufficient impedance bandwidths and gains for the 2.65GHz antenna which used the satellite digital multimedia broadcasting. The proposed antenna on a substrate, which is small enough to be installed in practical mobile phones. In addition, the proposed antenna decreases the construction complexity on the substrate. The proposed antenna is suitable for the S-DMB band. Details of the design and analysis of the proposed antenna are described and the experimental results of the constructed prototype are presented.

I. Introduction In the aspect of security, the 21st Century after the post-Cold War is forecasted as an age of uncertainty being affected by the centripetal force of compromise and cooperation but on the other hand by the centrifugal force of feud and dispute. Under this uncertainty, it is very important to grasp the point on the planning and system of security environment as well as that of the neighboring four countries in order to understand the problems on the Korean peninsula as it is. Especially, to grasp the planning and system on the relationship of military cooperation among six countries in the northeastern Asia ? such as, Korea, the U.S.A., Japan, Russia, China and North Korea ? is an indispensable factor in establishing the security policy of Korea. Therefore, this study aims at grasping the point of unsettled security environment in the northeastern Asia and groping for drawing up a plan enabling to contribute to the settlement of peace in the northeastern Asia ! and the Korean peninsula by analyzing the real state of military cooperation' s planning and system in all areas of the northeastern Asia from the viewpoint of compromise and cooperation. In order to analyze the military cooperation' s planning and system in the northeastern Asia, fist of all, I applied to the method of putting all bilateral military cooperation between individual countries, such as Korean- American relations, together. The bilateral military cooperation between individual countries is analyzed mainly at the point of cooperation background, recent cooperative actual condition and prospects. The results of this study are as follows: Firstly, the military cooperation relationship of the northeastern Asia around the Korean peninsula has a distinguishing feature of diversification and activation than that of the Cold War. The leading role of the powers of the world in the military cooperation relationship of the northeastern Asia remain the same as that of the Cold War but Korea seize an opportunity of playing a leading part in the military cooperation relationship among China and Russia and of changing the ROK-U.S. military alliance to the equal relationship being based on the relative superior economic power that that of the old the Communist bloc. Second, the estimated type of military cooperation in the northeastern Asia around the Korean peninsula may be the antagonistic relationship of changed the eternal triangle in the south and the north by "tentative discord structure between the U.S. and China" . That is to say, the military cooperation relationship in the northeastern Asia after the Cold War does not come out in the open as like the discord structure between the U.S. and the Soviet Union but involve a potential discord factor. The formation of cooling relationship between the U.S. and China is a good example. We must understand the foreign military strategy ? groping in the dark the increase of military influence in the northeastern Asia - of powerful countries around the Korea peninsula clearly. In this condition, the security strategy of Korea can be considered at the three ways. First, we have to consider what the most suitable direction for the security environment in Korea is? Second, how to approach to neighboring countries to establish the aforesaid security direction? Third, what should be done in the aspect of inner of Korea? First, the security policy of Korea should be changed from the North Korea-centered concept to the all-directional concept. In due consideration of geopolitical character of Korea, we should discontinue the exclusive alliance relationship, which obstructs the security profit of neighboring countries and instead of it, have to develop the diversification strategy in the military corporation since 1980' s. We should construct a cooperative relationship based on local joint benefits and we make the North Korea to participate in this cooperative atmosphere. Second, it is more realistic way that the military cooperation among the neighboring countries is made step by step. Namely, we should grope for a bilateral agreement or multilateral agreement through mutual trust and mutual interchange stage. Third, we should make a condition so that the military cooperation can be put into operation at home. In these days of the security environment, the military cooperation is not necessarily is confined to only soldier or military institute but it must be a national-wide and racial operations collecting all the National Assembly, Governmental Organization, Koreans abroad, etc. However, it should be kept in mind that the strengthening of mutual cooperation with the neighboring countries must not be interpreted as the aggravation of the relationship to the U.S. In this time that the North Korea acknowledged the nuclear development program, as long as we are threatened by conventional war, Korea has the necessity of adjusting the security cooperation with the US. by connecting the development of South and North Korea' s relationship. Of course, the aim of military cooperation must be linked to the national goal. According to the change of the drift of affairs in the world, the dynamics and military cooperation relationship in the northeastern Asia is now changing. The cooperation structure of the Korea-U.S.- Japan Security Treaty and North Korea-China-Russia is also changing. That is to say, after the terror of Sep. 11, 2002, the U.S.A. succeeded to obtain the military cooperation relationship with China and Russia. Therefore, the character and type of the military cooperation relationship in the northeastern Asia tends to the center of the U.S.A. The stage of tension being made newly from the new political environment of the North Korea after the summit conference between the South and the North of Korea and the proposal of "Criminal Group" by the U.S.A. after the terror of Sep. 11, 2002 may cause rapid change in the military cooperation relationship in the northeastern Asia. The military cooperation relationship in the neighboring countries around the Korea peninsular and the discord factor among nations being caused by the acknowledgement of the North Korea' s nuclear development program will be a new task to be settled.

이 연구는 디지털 미디어 테크놀러지인 미디어 파사드와 프로젝션 매핑 등의 기술을 이용하여, 대한민국에서의 개 식용 문화에 대한 생각을 바꾸려는 작은 시도이자 캠페인이다. 대한민국은 세계적으로 개를 먹는 몇 안되는 나라이며, 이것 때문에 해외에서 많은 비난을 받기도 했다. 개를 먹는 행위가 도덕적으로 말이 안된다고 말하려는 것은 아니다. 다만 한국에서 개를 먹는다는 것이 어떤 것인지 사람들에게 실상을 알리고 그에 따른 적절한 권한과 책임을 알리고 싶은 것이다. 연구의 앞부분에서는 해외의 미디어를 이용하여 공간을 꾸민 다양한 사례들을 살펴볼 것이다. 그리고, 그 중에서 고정된 공간이 아니라 임시로 세워지거나 이동이 가능한 형태에서 디지털 미디어가 어떻게 사람들과 커뮤니케이션 하는지 살펴보고자 한다. 특히 프로젝션 매핑 기술에 대한 이해와 최신 기법들을 간단히 소개하였다. 그 다음에는 국내에서 개 식용 현황과 중요한 쟁점들을 간단히 정리하였다. 마지막으로 쇼와 관련하여 레이어 소재의 특이성 및 실제 전시에 필요한 기술들, 개발 프로세스 등을 정리하였다. 실제 전시가 이루어졌을 때 사람들이 보인 반응들도 간단히 정리하였다. 이 연구를 통해 미디어 파사드와 프로젝션 매핑을 국내에 좀 더 널리 알리고, 아울러 개 식용 문화에 대한 보다 심도 깊은 대화가 이루어 지기를 바란다. Coming 21 century, there is a fad of experience. 4D movie has become a surprised skill in theaters and expo and 3D TV has booming at home. Digital media technology has deeply entered people’s live. Do we need to inactively follow the change? Or do we need to actively try by using it? People erect a stucture in the public space, appreciate and give meaning to the structure. All this Human behavior while meeting a variety of digital media has been constantly evolving. The result of evolution of visual technology, such as Media Facade, LED Signboard, attract people’s attention. The projector has the characteristic projecting the light on the screen bigger than the computer monitor, so it is used as the useful appliance not only in the movies and performing art, but also commercial performance. In this art field, projection mapping technique is developed, and is used to construct the space effcitvely. The purpose of the study is to analyse how projection mapping is used to construct the space in the art field with the pre-existed cases, advance the appliable new mapping technology, and show the forward possiblity of the mapping techniques. also, this study is meaningful that suggests an media art installation, “Project Droy”, as an effective methodology to interact with digital generation. For that, We researched Media Facade based media artworks Which lead to spectator’s active participation and analyzed their tendency towards multiple user participation.
