In this study, it is quantitatively analyzed for thermal Characteristics of isolation-heat paint which has been supplied to a domestic market through experiments and simulations. In the case of experiment using the container box, it shows 8% decrease on cooling energy consumption in a summer season, but shows increase on heating energy consumption. As a result, the analysis has found increase of energy consumption. As a result of holding simulations with meteorological data of domestic major cities, it shows an increase of energy consumption in domestic condition, and it is hard to expect an energy saving from the isolation-heat paint unless greater air-conditioning load.

Sprinklers are a necessary device for the early suppression of fires to prevent large fires. The installation has been obligatory for certain buildings recently through the digestion method. In an aging building, it is difficult to find sprinklers, because of their significant cost, long installation times, and they require installation by experts. That is why we are able to install all, was designed with enough independent integrated sprinklers with fire-extinguishing capabilities. The designed sprinklers are fitted with a conventional sprinkler head in a container of 20cm * 20cm * 10cm. Inside the container and potassium carbonate, which warms the rubber material and the plate line by pressing the potassium carbonate, the line weight is a 5kg pressing plate at the entrance at the pressure of 0.5Mpa when operating. The glass sprinkler valve blocking the entrance at about $68^{\circ}C$ is operated open. At this time, the potassium out of the digestive fire to combustible materials and heat off a chain reaction.

The Seoul Housing Corporation pronounced an alternative design competition and a bidding for Eunpyeong New Town in December of 2004. At first many construction companies were interested in the first New Town Project. But at last a few companies had proposed the alternative design and construction cost. This project needed a conjunction of design ideas and technology know-hows. And the client wanted the brand power of construction company. Ultimately the Corporation hoped that the first New Town Project will end up with high quality successfully. This competition had started with the original construction drawings. Then it needed some alternative ideas and the lowest cost. There were two drawings of non changeable part and changeable part. Non changeable parts are structure like housing unit plan, underground parking lots. Changeable parts are outdoor layout, interior design and building facade. So we tried all ideas of landscape technology and design principles within limited guidelines. The author applied new technology like tilted rooftop greening and sustained container greening on high-rise apartment house. This green technology will be the first trial in Seoul and in the world as well. Daewoo Corporation have accumulated greening technology through the researches by national funding since 2002. Through this New Town Project the green technology will go forward step by step.

In this paper, a tuned liquid1) mass damper(TLMD) was proposed and experimentally investigated on its control performance, which can control bi-axial responses of building structures by using only one device. The proposed TLMD controls the structural response in a specific one direction by using a liquid sloshing of TLCD. Also, the TLMD reduces the response of structures in the other orthogonal direction by behaving as a TMD that uses mass of the container itself and liquid within container of TLCD installed on linear motion guides. Force-vibration tests on a real-sized structure installed with the TLMD were performed to verify its independent behavior in two orthogonal directions. Test results showed that the responses of a structure were considerably reduced by using the proposed TLMD and its usefulness for structural control in two orthogonal directions.

Bong-amsa Temple is a special temple in the custody of Jogye sect, a branch of Buddhism in Korea. Due to limited public access to this temple, its Geungnakjeon(paradise shrine) has been little known to outside. But it is known that the Geungnakjeon has been not yet explored from academic standpoints in terms of its historical establishment as well as applications, and it would be two-storied wooden pagoda or the like. In order to examine its historical establishment, this study investigated historical records related to Bong-amsa Temple and its intrinsic architectural style. As a result, it was estimated that the building was established around the transitional period ranging from the late Koryo dynasty to the early Joseon dynasty. And it was found that the Geungnakjeon is not the two-storied wooden pagoda, but the unique building including an incidental component called Chayanggan(遮陽間; a sort of stepped penthouse) in Korea. In order to examine its possible applications, this study compared this building with other Buddhist funeral articles in forms similar thereto, such as Buddhist pagoda(僧塔), sarira container(舍利器) and Gamnodo(甘露圖) which depicts Byeoknyeon Daeban(碧蓮臺畔; a palanquin carrying malignant spirit). Then, this study estimated its possible applications on the basis of relevant historical literatures. As a result, it was found that this building was used as Wondang(願堂; a sort of Buddhist prayer house) to wish royal family's going to Nirvana after death, and it was not Confucian-style architecture popularized in the era of Joseon dynasty, but Buddhist-style architecture built widely from the era of Koryo dynasty to the early Joseon dynasty.

As national economies globalize, demand for intercontinental container shipping services is growing rapidly, providing a potential economic boon for the countries and communities that provide port services. On the promise of profits, many governments are investing heavily in port infrastructure, leading to a possible glut in port capacity, driving down prices for port services and eliminating profits as ports compete for business. Further, existing ports are making strategic investments to protect their market share, increasing the chance new ports will be overcapitalized and unprofitable. Governments and port researchers need a tool for understanding how local competition in their region will affect demand for port services at their location, and thus better assess the profitability of a prospective port. We propose to develop such a tool by extending our existing simulation model of global container traffic to incorporate demand-side shipper preferences and supply-side strategic responses by incumbent ports to changes in the global port network, including building new ports, scaling up existing ports, and unexpected port closures. We will estimate shipper preferences over routes, port attributes and port services based on US and international shipping data, and redesign the simulation model to maximize the shipper's revealed preference functions rather than simply minimize costs. As demand shifts, competing ports will adjust their pricing (short term) and infrastructure (long term) to remain competitive or defend market share, a reaction we will capture with a game theoretic model of local monopoly that will predict changes in port characteristics. The model's hypotheses will be tested in a controlled laboratory experiment tailored to local port competition in Asia, which will also serve to demonstrate the subtle game theoretic concepts of imperfect competition to a policy and industry audience. We will apply the simulation model to analyze changes in global container traffic in three scenarios: addition of a new large port in the US, extended closure of an existing large port in the US, and cooperative and competitive port infrastructure development among Korean partner countries in Asia.

The container throughput of China, after the joining in the WTO, has begun to increase notably. As a result, China is busy building new ports continuously. In accordance with China's situation Korea promote the development plans of ports and marketing strategy to attract the increasing cargo traffics with China, including transhipment cargoes. To build the competition strategy and the panning port for trading cargoes with China, an analysis on origin/destination is necessary. The cargo volume from/to the particular port(Korea/China) and origin/destination of traffic are important factors in the requirement for the port development. Therefore, in the era that trading with China is rapidly increasing, this study is performed to analyze the port's usage of transporting the cargos and the origin/destination of trading cargoes with china. Also this paper suggests to the competitive strategies of Pyungtaek Port to attract cargoes particularly from/to China.
