The aim of this study is to identify the floor plan types of folk houses or traditional vernacular dwellings found in Nagan Folk Village located in Joellanamdo province. Examining the floor plans appeared among 36 vernacular folk houses presumably built in the 19th century in the village by means of the changes in the number of bays of Anche, the mail block of the house, the study was also able to construct a spatial compositional process of floor plan development. The floor plan examination revealed that the basic floor plan type in Nagan folk housing was '一' shape, a typical southern dwelling based on the existing classification. This basic type is consisted of three bays or rooms: Jeongji (kitchen), Anbang (large room), and Jageunbang (small room). New spaces or rooms are added to this three room house to expand the house as the residential functions become more complex, such as more living and storage spaces. The expansion appears to have two direction. On the one hand, it has been taken place by inserting Marea, an open wooden floor living space between Anbang and Jageunbang to meet the extended living demand. On the other, Jeongjibang, a second kitchen/storage has been attached to Jeongji outward for extra cooking and storage. This two-way expansion shows the trend of symmetric expansion between cooking, storing space and dwelling space. It can be implied that the arrangement of house rooms has been structurally formulated and shared by the farmer-builders in the 19th century in Nagan village who appeared to be influenced by fixed images for housing.

As a result of analyzing the floor plan shown in the three drafts, there were a great deal of differences in composing the space of the inner main hall. The inner room facing to the east with the arrangement crossing the inner floor at right angles in the 'Baekdangguje Draft' faces to the south in the east or west in front of the main house thereafter. This represents that it reflects the intent of the owner of the architecture emphasizing the size increase and ceremonies of the main house in the 'ㅁ shape', which has changed to the directions of easily accommodating the Confucian ceremonial activities in the floor plan of the inner house as the size of the main house was gradually increasing from 24 sections to 30 or 38 sections. The expansion in the size of main house further divided the functions of floor into one for daily life and the other for ceremonies as well. In other words, the 30 Sections in Yijeong Draft as being the first planned draft for reconstruction had a hall for memorial services in the main hall of the inner house, whereas the 'Draft with 38 Sections' as being the second planned draft for reconstruction was planning a room with a floor (two sections of Bangdang) for memorial purpose in the back of the inner main hall. The variations in the guest house (or space for men) shown in the drafts confirms the establishment of space for men as the size of the main house increases. We can see the change that a large guest house is placed over the south and in the south and east of the main house as the number of main house increases by 30 sections or 38 sections. Especially, a guest house with a wide space in a 'ㄴ shape' is arranged from the south of main house to the east wing in the Draft with 38 Sections. In addition, the backward sections are advanced in the front and back of guest house in the drafts with 30 and 38 sections, while a back floor or a back floor connecting to the back room or sleeping room or inner house is installed in the backward sections.

The purpose of this study is to analyze the unique characteristics of the vernacular house of Ulleung-Do(island), which shows a different residential culture from the main land. For this purpose, this study examined the characteristics of the location, spatial arrangement, and floor-plan of the house and also tried to understand how these basic elements were changed and why these changes were occurred. The result of this study is as follows: First, the house was located on the mountain area and was oriented toward the various bearings. Second, the house usually did not have annexes and most residential space was installed on a main building. Third, the floor-plan of the house was developed from a basic two-Kan (with single row) house type in a early settlement period to three-Kan, four-Kan, and five-Kan house types in later periods. While the development of house type proceeded. the main building was functioned as a complex space for both residential and storage purposes. Some houses were gradually developed into a middle and upper-class house shape by installing annexes. The change of the floor-plan and the house size was the result of self-sustained living culture influenced by the natural environment of the island and of changes of residential conditions as well.

This study is a basic investigation of the contents and services relevant to the domestic vacation house business. In which, the trade scale, types of housing, and environmental conditions of various property locations were analyzed. The characteristics of properties listed on the Japanese website that conducts the greatest volume of vacation house trade in Japan were examined, and the following results were obtained: Villa areas, villas, and resort condos (resort mansions) are the three basic types of properties handled in the vacation house trade. In this market, sales per unit in villa areas and per spaces in resort condos accounted for the highest volume of trade, followed by that of villas (individual houses). In terms of land area, floor area, and sales price per house type, the relatively cheaper small and medium-sized vacation houses are more frequently traded, than expensive large-scale villas. In particular, small multi-family type villas (such as in resort condos) are the most popular. Land and floor area, and sales prices all show considerable variation depending on the type of property considered. Therefore, a business initiative to provide a more detailed classification of properties is required. In terms of the environment of vacation properties, most are located on coasts, plateaus, or inland mountains, and are generally within three-hours' traveling distance of large cities.

The Restroom in house have a main role of bath, excretion, and washing hands. So there are usually bathtub, washbasin, and chamber pot. But the actions of bathing, excretion, and washing hands are not always occur at the same time. So the necessary of sectioning the restroom's space is introduced. In Japan they have some different methods in planning the restroom space. They separate the roles of bathroom and toilet, and develop several types of restroom. And they applicated the several types of restroom to appropriate spaces and floors. These sectioning the restroom's space make the moving line rational and take off the waste of spaces.

In this study, numerical analysis is performed to investigate the sound radiation characteristics of an apartment house according to the type of the slab system. In order to satisfy the boundary condition of the apartment house, the whole floor is modelled with FEM model for three different structural system: wall, RC, flat slab system. From the analytical results, it Is shown that heavy weight floor impact noise of wail type slab is larger than that of the other slab systems and the noise radiated from the wall have great effect on the sound pressure level. The results also show that the vibration energy of RC or flat slab system is widely distributed over the whole slab, which is main reason that the noise induced by the slab systems is reduced in comparison with wail slab system.

In the summer, the irradiated solar heat gain through the roof has an effect on the thermal environment of the top floor units of apartment houses. This paper investigated the differences of the indoor air temperature, globe temperature and thermal comfort index between the top floor unit and the middle floor unit by measuring them at the sample units on the condition that all the openings of the units are opened. The purpose of this paper is to provide quantitative data about the irradiated solar heat gain during the summertime through the roof of an apartment house and these data to be the source to reevaluate the appropriate roof insulation efficiency. From this study, we obtained three brief results as follows. Indoor air temperature difference between the two sample units shifts a day. Indoor air temperature at the top floor unit is $0{\sim}1.8^{\circ}C$ higher than that of the middle floor unit from 12:00 p.m. to 12:00 a.m. and $0{\sim}2.8^{\circ}C$ lower from 12:00 a.m. to 12:00 p.m. The evaluation of the indoor thermal comfort index and the globe temperature shows similar results as the indoor air temperature measuring. Results of this experiment verified the actual existence of indoor air temperature difference between the top floor unit and the middle one and this difference comes from the heat storage of the roof.

Background: Human exposure to phthalates in indoor environments occurs via dermal absorption, oral ingestion of indoor dust, and inhalation of indoor air. However, systematic studies to investigate the exposure rate to phthalates among the three exposure routes in indoor environments are currently limited. Objectives: A theoretical exposure ratio between inhalation and oral exposure was calculated based on the total amount of di(2-ethyl-hexyl) phthalate (DEHP) emitted into indoor air and deposited into floor dust in a test house. Methods: Flooring and wallpaper containing DEHP were installed in a test house and the concentration of DEHP in both indoor air and floor dust were monitored for five months. Based on the measured DEHP concentrations, the theoretical total amount ratio of DEHP that could be exposed through inhalation and oral ingestion was calculated. Results: Considering the period of operation in the test house, the theoretical total amount of DEHP through inhalation and oral ingestion exposures in the entire test house space was calculated to be 0.014 mg and 5.5 mg, respectively. The exposure ratio of the two routes between inhalation and oral exposure corresponding to the total DEHP amount in flooring and wallpaper was 6.0×10^-7% and 2.3×10^-4%, indicating that theoretical oral exposure to DEHP is approximately 380 times higher than inhalation. Conclusions: Monitoring results from a test house has shown that oral exposure is the main exposure route for DEHP in indoor environments. The experimental design employed in this study and theoretical exposure ratio obtained can be applied to investigate actual exposure to DEHP and to determine the exposure characteristics of various types of semi-volatile organic compounds.
