Information Centric Networking is changing the way how content is being transmitted. The shift from IP and host based networking towards content based networking scenario is growing day by day. Many researches have been done about different frameworks of ICN. Caching is an important part of ICN and many researchers have also proposed different ways for caching the data. With caching of data in intermediate devices like the network devices as well the user devices in some cases, the issue of content security as well as the role of the content producer becomes a major concern. A modified ICN architecture based on the current Content Centric Networking (CCN) model is presented in the paper. The architecture mainly focuses on involving the content producer in content delivery in the real time. The proposed architecture provides better security aspects for the CCN architecture. Apart from security the paper will also consider the issue of applicability of CCN architecture to replace the TCP/IP based architecture. The efficiency of the proposed architecture is compared with the previous CCN architecture based on the response time for a content delivery which shows very comparable level of efficiency. The paper than analyzes different beneficial aspects of the proposed architecture over the current architecture.

In recent years, many environmentally disastrous oil spill accidents from damaged vessels become worse especially when the early treatment is not prompt enough. To properly handle this type of accidents and prevent further disasters, international organizations establish and impose various rules and regulations. In assessing the damages and providing salvage operations, the propulsive performance of damaged vessels is of great importance, as well as for containing oil spill while the vessels are being towed or self-propelled. Until now, many naval hydrodynamics researches have focused on the propulsive performance in normal operating conditions and only a few studies for damaged vessels are found in literature. In this paper experimental method is used to study the Propulsive performance of a very large crude-oil carrier (VLCC) in .heeled and/or trimmed conditions.

This study intends to understand the visual experience of architectural space generated by users' movement based on the interpretation of visual properties. An analytic theory of Isovist is suggested for the objective and comparable measurement for such visual experience, and a computer program for the analysis has been proposed as well. By using the analytical theory and computer program, eight houses designed by Adolf Loos and Le Corbusler are analyzed for the purpose of understanding the visual characteristics of the Modern Architecture and the contemporaries. The result shows that, while the architectural space of Loos emphasizes personal privacy as for being livable spaces, the architectural space of Corbusier emphasizes users' movement as for including diverse visual arrays. These commensurable results exhibit that the analytical tool and research frame suggested in this study can be a competitive tool for such analysis.

In a modern society, as the architectural materials have become main subject of the interior design expression, their influence on architecture is becoming substantial. There are multiple ways of using architectural materials. The aesthetic value is greatly enhanced by the fact that the architectural materials can be used to create unrestricted and new expression. The modern time is uncertain and rapidly changing. In this era of chaos and diversity, the materialism is being superseded by idealism. Speedy exchange of information among the countries with development of new technology and materials increases the possibility of new expressions. Each new material that adds new value influences on the other art as well as the architecture. These characteristics of new expressions could be viewed as having close relationship with current idealism. Therefore, the study on the expressive trend of architectural materials will provide better understanding and translation on expression of interior design. At this point, this study has a purpose in not only understanding architectural materials but also researching for the characteristics of expression on interior design with consideration of paradigmatic variation in modern times.

The changes of prison facilities in the age of Enlightenment and Industrial Revolution, implies viewpoints architectural space as a representation of power. The aim of the study is to examine the structuralistic approach based on two authors of Michel Foucault and Robin Evans. Both texts are summarized and analyzed to make comparison. While Foucault concentrates upon the ideas relating to punishment which preceded and led to the prison being adopted, Evans regards the reality of punishment as it was executed in its architectural context. The study compares the fundamental difference between the two texts; the approach that each author takes with regard to the central issue of the history of penality. These two different interpretations dictate the framework of each discourse and has resulted a number of different notions of ideas. By comparing divergence and convergence of the texts, the study analyzes each author's methodology, theoretical position and notions of prison. Keywords are also extracted to articulate the study and each author's arguments as well.

Go-Sul-Sik(高設式) On-Dol(溫突) houses have a combination of high Ma-Ru and high On-Dol structure. This type of house had been developed in the process of combining Ma-Ru with On-Dol. Go-Sul-Sik On-Dol houses give a clue to unveil exchanging process of Korean On-Dol and Ma-Ru. Go-Sul-Sik On-Dol can be understood as an architectural type of introducing On-Dol into the upper classes' Ma-Ru afterwards. Apparently, Go-Sul-Sik On-Dol houses were not a two-story building. But they had a two-story structure because of On-Dol rooms, which implied a symbolic rank and On-Dol's practicality as well as its being high. Go-Sul-Sik On-Dol houses were peculiar architectural type which realized lives of the very individual authority and symbolic representation within the strict Confucian society. It seemed to be derived from an alternative of the upper classes' architectural culture integrating an ideal into reality.

Recently with the demand of well-being is increased, the demand for indoor thermal environment and air quality is increased. According to this circumstance, many people in Korea note the traditional architecture that is made by natural materials, such as a soil, stone and wood. However, few researches regarding the indoor thermal environmental characteristics of the Korean traditional houses is reported. In this study we analyzed the indoor thermal environment for Han-ok through field measurement. Moreover, based on the field measurement results. indoor thermal comfort in Han-ok is analyzed.

As we have come to realize the problems caused by the modern civilization as well as the importance of the preservation of nature. Ecological building and urban design come to attract more attention. Therefore, the object of this study is providing the design factors and improving the design methods for the developments of ecological housing complex, harmonious with environment. Followings are the results of this study: 1. We need to turn to new trend-Ecological architecture which enables the co-exitence of nature and human being to come over the presence and face new decades. 2. Ecological architecture is based on energy-saving system and give people a healty and comfortable atmosphere. 3. In the city area, the house development should be undertaken to minimize the environmental problem through extremely high ehhiciency and technonogy. 4. We need a new development to preserve natural environment in the suburvan and small or medium city. 5. We have to develope the approach method, which is to maintain the frame of present ecological environment, to be in sympathy with geomorphology, to use the natural material in the rural community.

There is something valuable in Korean traditional architecture that does not change even after more than a number of years. Each design element of traditional houses has its own role to embody natural, healthy, and environment-friendly architectural planning. With traditional already-built examples located in the northern area of Gyeongbuk province, this study attempts to untangle some of the daylighting control issues in opening design. By looking at more than just photometric materials, at some threshold level, the whole of daylighting control characteristics of their openings is being surveyed from the viewpoint of geometric relationship between their roof structures and windows. As a glazing material, in addition, Korean traditional window covering paper, Changhoji, is evaluated for its transmittal performance under artificial and real skies as well.

As the population of the elderly increases drastically year by year in Korea, this phenomenon is being a serious problem because of the increasing speed not having been showed ever all over the world. This thesis would propose the space organizing features for well-organized dementia hospital focused on the public living space. The way arranging each function is very important because values of the physical and functional accessibility have a wide range of value as each type of facility. Moreover, if the arranged function unit is the same as the territory of the space, it could be a good guideline on architectural planning.
