This study investigated the smoke blocking and control systems for the safety of residents evacuation and for the prevention of smoke spread through the central corridor in the event of central corridor type of intelligent building fire. We offered additional ways of utilizing smoke ventilators and intake ventilation equipment and utilized CFD-based fire simulation program(FDS Ver.5.5.3) in order to analyze the effect. As a result, many differences in the smoke block effect, depending on the application of smoke ventilator and location of installation, was found. In addition, the result was found that larger effect was showed not in the case of application of smoke ventilator in central corridor only but application in fire room. The reason is that the smoke leakage is blocked primarily as air is flowed in the fire room through open door by operation of intake smoke ventilator in the public corridor and secondarily, the smoke leakage to the public corridor could be blocked as fire and smoke were released to the opened smoke ventilator continuously. Especially, the effect was maximized through complex interactions by applying smoke ventilator and intake ventilation equipment in corridor together rather than applying smoke ventilator and intake ventilation equipment independently. The proposed measure through this study shall be considered from architectural plan as one of ways for blocking from smoke spread to the central corridor in the central corridor type of intelligent building. In addition, flaws on regulation shall be established and supplemented.

For one hundred years, the Chinese character is good or poor? Is it easy or Complexity? Should continue to go its own way, or take the 'world of common phoneticdirection'? Repeatedly set off a heated debate until the new century, the problems have not been fundamentally resolved. The authors think that these arguments completely resolved, depends on the proper distinction, aware of two eras: the era of type and the computer age. In other words: the correct understanding of the new features of today's computer age is the key to Chinese characters all kinds of disputes resolved. Summary explanation: a century of Chinese characters should distinguish between two eras: type times and computer age; computer era of Chinese character information processing efficiency has alreadyovertaken English;electronics and software technology has beensuccessfully cracked a large amount of Chinese characters, the complex structure of the various problems; simplified and traditional Chinese characters compared in two age has a radically different landscape; implified and traditional Chinese characters compatible coexistence of conversion, wonderful, bright and harmonious development prospects.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time(1905~1919), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

Recently, Earthquake occurrence in korea has become frequent, and the seismic safety of low-rise piloti buildings becomes more and more important. In this study, the differences in seismic performance between before and after reinforced by concrete filled steel tube (CFT) of low-rise central core type piloti building structures were compared.
