Mangroves are important coastal ecosystems and are located at the inter-tidal zones of tropical and sub-tropical belts. The global mangrove forests are declining dramatically because of the conversion of forests to shrimp farming, over-exploitation, pollution and freshwater diversion. The Bangladesh Forest Department initiated mangrove afforestation throughout the coastal belts of Bangladesh in 1966 to provide better protection for the coastal communities. Up to 1990, 120,000 ha of mangroves had been planted and it is one of the largest coastal afforestaton programs in the world. The objective of this study is to exploit the spatial extent of mangrove plantation and their dynamics of changes over the last two decades using multispectral Landsat imagery. The study area covers the coastal areas of Bangladesh that is extended over the eastern part of Sundarbans up to Teknaf, the southern tip of mainland Bangladesh. Mangrove plantations were interpreted visually on computer screen and interactive delineation of forest boundary was done. The mangrove plantation area has been estimated as 32,725, 47,636 and 43,166 ha for the year of 1989, 2000 and 2010, respectively. Mangrove deforestation by human activity has increased almost six times in the recent decade in comparison to the previous one. The mangrove forest loss due to coastal erosion has slightly declined in the 2000s. Mangroves have been lost primarily because of agricultural expansion. The result of this investigation will be helpful to understand the dynamics of mangrove plantation and the main drivers of changes in this coastal ecosystem.

삶의 질을 향상시키기 위한 유비쿼터스 테크놀로지 도입으로 인해 제품개발, 주거, 상업시설 등에서 시작하여 최근 유비쿼터스 환경 구축의 일환으로 u-City 구현에 중점을 두고 많은 연구 진행되고 있다. 그 중 가로환경 디자인은 공공 시설로서 유비쿼터스 환경 구축의 중요한 이슈가 되고 있다. 그러나, 오늘날 가로 공간은 그 수가 양적으로 팽창되었을 뿐 각각의 특색에 맞게 조성되고 있지는 못하며, 물리적 환경개선에 중점을 두어 단순한 가로정비 수준에 머물고 있다. 이로 인해 지역주민과 이용자 중심의 참여에는 부족한 면이 많았다. 이에 본 연구는 유비쿼터스 테크놀로지를 도입하여 보다 실용적이고 현실 참여적인 공간으로 디자인함으로써 새로운 u-Street 디자인을 제안하고자 한다. 또한, 이와 같은 공공장소에서의 서비스가 이용자들과 어떠한 인터렉티브 커뮤니케이션을 가질 수 있을지에 대해 살펴보고 이를 디자인에 반영하여 공간이 인간과의 상호작용을 원활히 하고 감성적인 공간 디자인이 될 수 있도록 u-Service 를 개발하는 데 중점을 두고자 한다. 본 연구는 부산 광복로를 사례로 진행되었으며, 그 결과 다음과 같은 측면에서 기대효과를 예측할 수 있다. 첫째, u-City 의 기반 시설로서의 u-Street는 수평적이고 친환경적인 가로 경험을 통해 사람이 직접 여러 서비스와 인터렉션할 수 있다. 둘째, 본 연구에 제안된 u-Service 는 이전 광복로의 침체되고 비활동적인 공간을 활동적이고 생동감있는 공간으로 재활성화시키는데 중요한 매개체로서의 역할을 하게 될 것이다. 셋째, 주민과 이용자들의 적극적인 참여를 유도하여 지속적인 공간을 만들어 내는 데 크게 기여할 것이다.

Language and letter are represented by a combination of its signifier and signified. All symblos are commonly calling direct attention to people who are living in the physical world. However, in cyberspace, the image takes control once inhabited by the language. Cyberspace with anonymity and deoent physical nature has something with physical laws. In this space the statue transcends the imaginary realm. Ideology gives a greater connotation by giving a series of regulation to images floating in cyberspace. Even if various media have the same image, the meaning of the image changes depending on which ideology is used. The impact of this on the public is great. In this study, I discuss the ideology in cyberspace where is supposedly wide open to who visits and spreads all the thoughts without suppression and the human body. The main ideas would be who owns the ideology and what does it want to control and how the people would react to the ideology. This paper would eventually head the prototype that visualizes above ideas. Though the interactive media it will also show the subject in the real world is accept the images floating in the cyberspace without any doubts.

Technological development of information and communication have brought sharp changes to every sector such as society, culture, economy and education because of knowledge and information-oriented society. The number of classes has decreased, and some schools are closed or incorporated due to decrease of the population. Such phenomenon has brought changes to learning using digital technology and space. A change called digital innovation is characterized by interactive communication centering on the internet network. Therefore, it is very important to predict educational environment to be changed according to digital environment and to note how real learning space is changed. The development of digital technology in society in general presents two concepts of digital and contents, digitalized information. Such technology is recognized as a new paradigm in education sector and a new space is created through participation of instructors and learners in learning space. This study analysed cases of learning space of elementary schools based on bibliographical examination and related bibliography including data from academic presentations and news release to present developed leaning space. To present healthy and creative learning environment which can lead knowledge and information-based society in the future, the preface described the background, purpose, methods and range of the study, and analysed transitional processes of society and culture, digital learning contents, and learning space in education of elementary schools. Finally the study identified trends and cases of research on learning space and suggested digital learning contents space.

Purpose: While medical standard is rapidly improved, welfare of users and employees in hospitals is not treated correspondingly. Intercommunication of hospital users is thought to be very important for their welfare, and provision of conversation spaces within hospital environment needs to be expanded by architectural design. Space organization methods for the design of conversation space is to be embellished. Methods: Literature and hospital designs are analysed in order to develop the basis of argumentation for the hospital conversation space. 15 hospitals are reviewed and designed spaces for the intercommunication of the users are examined, Space organization efforts and design experiments are identified, and 6 organizational methods are proposed such as: 1) reducing territoriality 2) flowing space 3) categorizing and separating spaces 4) height variation 5) contact with outside and 6) Sun-lighted space. Results: 6 organization methods are confirmed in precedent hospital cases, and these proposed methods are applied in a new hospital design project to verify their usefulness. Implications: A hospital design project is presented based on these proposed methods of organization for the conversation space. Outcomes of this study can be applied for the formulation of human intercommunication spaces in other facilities.

The change in radically changing era requires various interpretation of interior space and application according to it Minimalism shows simple and pure geometric structure and has been influencing to every aspect encompassing space till present. The features of minimalism in space is geometric structure and composition of simple and repetitive line, restrained simple space, pure and structural simplicity. When minimalism construction is discussed, the vocabulary of simplicity has been followed incidentally and has been discussed as concept of simplicity in new viewpoint through historical flow. The purpose of this study is analyzing basic features of John Pawson's ways of working and trying to define the semantics of the new simplicity concept in modern interior space. The new simplicity in John Pawson shows interactive relationship of eastern and western through basic consideration of fundamental elements such as space, light and materials. The relational simple in intermediation of the new simplicity expressed by amalgamation of eastern and western further from disparate interpretation for simplicity expressed in eastern and western is to review back the basic meaning of simplicity in minimalism. And I hope this study can offer various directions for new interior space accepting theory of the new simplicity and I think that new constructional alternative is required as physical space which can be matched with era of social, environmental chaos caused by this theory of the new simplicity.

We propose an active color model based method for tracking motions of multiple human using a networked multiple-camera system in IoT space as a human-robot coexistent system. An IoT space is a space where many intelligent devices, such as computers and sensors(color CCD cameras for example), are distributed. Human beings can be a part of IoT space as well. One of the main goals of IoT space is to assist humans and to do different services for them. In order to be capable of doing that, IoT space must be able to do different human related tasks. One of them is to identify and track multiple objects seamlessly. In the environment where many camera modules are distributed on network, it is important to identify object in order to track it, because different cameras may be needed as object moves throughout the space and IoT space should determine the appropriate one. This paper describes appearance based unknown object tracking with the distributed vision system in IoT space. First, we discuss how object color information is obtained and how the color appearance based model is constructed from this data. Then, we discuss the global color model based on the local color information. The process of learning within global model and the experimental results are also presented.

This paper discusses the interactive system for smart home environments. In order to realize this, the main emphasis of the paper lies on the description of the multiple signal processing on the basis of the technologies such as fingerprint recognition, video signal processing, speech recognition and synthesis. For essential modules of the interactive system, we adopted the motion detector based on the changes of brightness in pixels as well as the fingerprint identification for adapting home environments to the inhabitants. In addition, the real-time speech recognizer based on the HM-Net(Hidden Markov Network) and the speech synthesis were incorporated into the overall system for interaction between user and system. In experimental evaluation, the results showed that the proposed system was easy to use because the system was able to give special services for specific users in smart home environments, even though the performance of the speech recognizer was not better than the simulation results owing to the noisy environments.

테크놀로지의 발달로 전통적 공연예술 분야 에서도 디지털 미디어를 이용하여 표현영역을 확대하려는 시도가 증가하고 있다. 기존 공연은 영상을 단기 공연의 배경 정도로 활용하는 경우가 대부분이었으나, '미키쥐의 죽음' 에서는 이러한 기존공연의 표현 영역을 탈피하여, 미디어 테크놀러지를 이용한 영상, 퍼포머, 소리가 유기적으로 융합된 인터랙티브 퍼포먼스를 구현하였다. 이 결과, 미디어와 퍼포머 사이의 상호작용성 증가로 무대라는 연출된 공간에 더욱 큰 리얼리티를 부여하여 현장감이 강화되고, 표현 영역이 확장 되는 새로운 공연양식의 발전 가능성을 제시하였다.
