The purpose of this study is to investigate the change of wind environment for different building arrangement. In this study, we analyze outdoor wind environment on different building arrangement that take same floor area ratio using the CFD (Computational Fluid Dynamics) method. We do not consider the effect of temperature. Building arrangements of low density, different hight and a lot of green area will change the effect of wind environment. The eight different arrangements of buildings are studied in this paper. In these calculations, we know the different arrangement of buildings change outdoor wind environments. Especially, reducing the number of building and crossing the different height of buildings have a good kind of wind environment at the same floor ratio. We know that these arrangement of buildings to reduce the heat island phenomena on city plan.

The bureaucrat-scholars, ruling class of the Choseon Dynasty, used to build small private pavilions for rest and study for themselves. In the early period of the Dynasty, the pavilions had plain shapes with rectangular plan and simple wooden structure without any walls so as to enjoy the surrounding scenery. From the 16th century, the building form began to change into some diverse one by putting in an ondol room, an unique floor heating equipment. The pavilions also began to show regional differences by placing the ondol rooms in the floor. Myonang-jong, a pavilion occupied by a famous bureaucrat-scholar Song Soon, was built at Damyang of the southwest part of the Korean peninsula, so called Honam area, in 1533. At first, the building form followed the ordinary early pavilion shape using simple wooden structure and wooden floor. But when it was rebuilt in 1654 after burning down by war, there happened some changes. An ondol room was put in the center of the floor, of which regarded as a dominant regional characteristic of the Honam area. The change of the building form of Myonang-jong showed that it was the 17th century Honam area got the regional characteristic in the architecture of pavilion.

The purpose of this paper is to analysis on periodical changes of rural houses of Korean-Chinese people residing in Yanbian area, China focused on periodical changes of floor plans according to Chinese government's policies and regulations influencing on rural houses. Changes of floor plans are classified into four periods; immigrating settled period, 1960-1970s, 1980-1990s, and after 2000. Total number of 67 cases were analyzed that data was collected 48 cases of literature studies and 19 cases of field study in Yanbian, China. The results are as followings. In immigrating settled period, floor plans of the rural houses have tended to be continued the pattern of the Korean traditional rural houses. Nevertheless China was changed socialism system, rarely floor plans were influenced by the system during this period. From 1960s to 1970s, the livestock and rural mechanization are influenced by the "People's Commune" policy. The "Barn" and "Mill" were converted into "warehouse". The residential part consists of one Jeongji (space mixed dinning and kitchen) and one to three of Ondolbang (room). From 1980s to 1990s influenced by the policies of "Cultural Revolution", "Birth Control" and "Chinese Economic Reform", the Korean traditional customs like "elders first" and "distinction between the male and female have been gradually vanished. Meanwhile, spaces of the rural houses have consisted of Jeongji, big Utppang (room), and warehouse. Each space is opened and mutual. Since 2000, influenced by the policy of a "new Socialist Countryside Construction", the bathroom and kitchen are added in interior spaces, the life style in rural houses has been changed as for both the sedentary style and western style.

Floating floor is most commonly used at apartment houses in Korea for thermal insulation and reducing impact noise. But it in proven that the floating floor is not effective for reducing the floor impact noise in low frequency range. In most cases, impact sound pressure level under 63 Hz frequency band were actually increased by the resonance of resilient material, lightweight concrete and the finishing mortar installed on it. In this paper, an integrated floor system consist of 70 mm light weight concrete and 40 mm finishing mortar successively installed on the concrete slab was suggested to avoid the resonance. Integrated floor system increases total flexural stiffness and mass per unit area. The natural frequencies of first and second vibration mode were increased and acceleration response and floor impact sound level was decreased in all measurement range.

Actually, prediction formula of road traffic noise for EIA(Environmental Impact Assessment) has been used that proposed by National Institute of Environmental Research in 1999. The prediction formula, however, was calculated predicted noise level according to noise level producing on first floor, then needs to correct noise level at each floor in the case of apartment building. The investigation was carried out to calculate the correction coefficient for commonly using in EIA of large scaled apartment development areas. The noised level at each floor were measured from August 2001 to March 2002 at 31 investigation points of large scaled apartment development area in national wide. Measured data were divided and treated with 4 types as 3th floor, 5th floor, 7th floor and 10th floor and then the correction coefficients of each floor were calculated using by correlation formula according to each floor.

This study examines the classification and typical characteristics of 148 owner shop houses existing in the historical city center of Cheongju. First, they can be classified into single-story, middle-story, and divided types according to the distribution of residential and commercial functions. The single-story(36) has 'ㅡ', 'ㄱ', and 'narrow and deep'-shaped arrangement, with stores on the front and houses on the rear. The middle-story second floor(89) is divided into a first-story store and a second-story house, and the third floor(23) has different functions for each floor, but more than half of them have houses on the second and third floors. Among the total, there are also 16 cases in which the division type is taken with different construction times and structures. Second, in the position of the stairs connected to the upper floor among the middle-floor types(112), the outer stair type(52) to separate from the living space while making the most of the stores on the first floor accounts for 47%, but the biggest feature is that the inner staircase type(34) with privacy reaches 30%. The rear stair room type(26) entering through alleyways or private yards is also 23%. Third, the front pillar spacing varies from 1bay to 4bay in appearance, but the 2bay type on the 2nd floor and the 1bay type on the 3rd floor occupy the largest proportion. This exterior type is a characteristic of a owner shop house that can measure the range of personal ownership. Despite the conflicting functions of stores and houses, 35~40% of the cases are in which the opening positions of the upper and lower floors are unified.

The purpose of the study, approaching from the aspect of the construction technologies, is to determine the architectural techniques of traditional wood architects in existence, through which the systems and techniques that create the inherent characteristics of Korean Architecture are clarified. With understanding traditional construction system and focusing on the fact that built environment results from the consistent standards and technologies of architects, this study inquires into the systematic standard and its formation that present in the process of planning for the overall scale and shape of a building from the following (four) perspectives. The study determines the characteristics of '間(Kan)' (unit; fundamental unit that measures Korean traditional houses) and the methods of columns disposition of which the '間 (Kan)' is made up. Once the necessary spaces are decided according to the size of a building, then floor plans are drawn with the standard unit, '間(Kan)'. The '間(Kan)', as a modular unit, is not only composing the floor plans, but also functioning as an Area unit, Space unit and Structural unit. Composition of '間(Kan)' varies with disposition of columns, and therefore multiform of floor and spaces are created. In this study, the '間(Kan)', as a standard unit, is used in the form of specific size and area, and it is demonstrated how the floor plans are developed by organizing the columns in accordance with the spaces requested.
