In late 20th century, smart home market evolved in China, and absorbed best manpower and technology to commercialize the smart home equipment. Many foreign companies want to take possession of Chinese market, but not arrive at abundance yet. There has many reasons, but most important thing is ignoring the interaction between technical elements and spacial elements. in other words, ignoring the correlation between each industry. Korean smart home market evolved same period with Chinese, but it has balanced development in technic and application, so the commercialize and market arrived at poverty. In this study, survey the present situation of smart home about Korea and China, and compare the technical elements. In addition to analysis the interaction between smart spacial contents and technology. This study focused on the smart apartment, and analysis the strength and weakness in each country, and make theoretical basement for Korea to make certain about Chinese smart home market.

During the period from December, 1990 to November, 1991, dustfall samples were collected by deposit jar at 28 sites in Seoul area and the amount of deposits of seven dissolved components$(SO_4^{2-}, NO_3^-, NH_4^+, Na^+, Ca^{2+}, Mg^{2+})$ were measured. The total amount of deposit was in order of Spring > Fall > Winter > Summer, and the amount of soluble components were high in the northeast region (Sanggae and Jangwe) and southwest region (Sangdo, Kuro, Siheung and Oryu). Total amount of major soluble components highly depended on regional air flow rather than emission source characteristic, and showed the regional trend-Residential > Iidustrial > Commercial > Rural, and the seasonal trend-Winter > Fall > Spring > Summer.

An electricity consumption is closely related to the economic growth structure. The change of economic growth structure affects the pattern of electricity consumption widely and severely. This paper gives that the primary changing factors of electricity growth are economic growth, change of industry structure(the change of electricity consumption ratio in case of residential sector), and the effect of electricity saying. It gives a model to analyze the influence of GDP to the change of electricity consumption patterns by sector through the period of pre and post 1998(IMF, financial crisis) to observe the contribution of each factor to the growth of electricity demand. It is anticipated that this study shows the feasible scheme of economic structure to become the developed country.

This study was designed to investigate population dynamics of cigarette beetle, Lasioderma serricorne F.(Coleoptera, Anobiidae), at differential house types in Korea. In hot season, July 24 to August 24, cigarette beetle adults were captured by sex-pheromon-trap at all house types which were located in Wonjoo, Shintanjin and Suwon area. Cigarette beetle adults were captured only at apartments where located at same area by sex-pheromon-trap during overwintering period in Korea. No relation was detected between a limit of the distribution of cigarette beetle, L. serricorne F. and the distance from tobacco storage warehouses to houses in Korea.

Groundwater monitoring wells (about 70 wells) were extensively installed in 28 sites surrounding Lake Texoma, located on the border of Oklahoma and Texas, to assess the impact of geochemical stressors to shallow groundwater quality. The monitoring wells were classified into three groups (residential area, agricultural area, and oil field area) depending on their land uses. During a two-year period from 1999 to 2001 the monitoring wells were sampled every three months on a seasonal basis. Water quality assay consisted of 25 parameters including field parameters, nutrients, major ions, and trace elements. Occurrence and level of inorganics in groundwater samples were related to the land-use and temporal change.

Diffusion of innovation theories have been used to explain the adaptation process of Chinese college students to Korean food. This study examined and compared Korean food adaptation among Chinese college students in Gyeonggido and Daejeon. A total of 141 Chinese college students were surveyed from August 01 to November supported by the Chinese Students Association in Gyeonggido. The results show that the adaptation process of Chinese college students to Korean food was different between Gyeonggido and Daejeon. Chinese college students did not have many opportunities to learn about Korean food and search information about Korean food. The adaptation process of Chinese college students to Korean food was different by residential type and period. The adaptation process of Chinese college students in Gyeonggido to Korean food was composed of three factors: interest-reinvention-adoption, awareness, and evaluation-trial-adoption. Three factors of the adaptation process of Chinese college students in Daejeon to Korean food were awareness-evaluationtrial, adoption-reinvention-trial, and interest.

From the first customer located right at the substation to the last customer at the end of the line, voltage must be held within close limits, so the voltage regulation is more important than the thermal limit. On a typical distribution system during the peak load period, the voltage drop may be serious enough to cause unsatisfactory operation of home appliances in the residential area, and present many problems to manufacturing industries, where the voltage must be maintained within close limits to insure smooth operation. Among all the factors contributing to voltage drop in the distribution system, the voltage drop in the distribution transformer may account for 30% of this figure. If we can eliminate this factor, the power companies can provide better quality electricity to more customers with the existing distribution facilities, thus saving on initial investment costs. Taking all these problems into consideration, the author undertook the design of a capacitive transformer which would give zero voltage drop at rated load and at 80% lagging power factor while incorporating overload features to withstand 400% overload for at least 100 seconds. The following are the results obtained through design, manufacture and test of an initial experimental transformer built with these specific purposes.

One of the problems associated with the current system of land development projects implemented by the public sector in Korea is that various service facilities are not ready in time for the occupation of residential dwelling. A major cause of the problem is the lack of financial arrangements which would smooth the cash-flow of the suppliers of the facilities during the project period. In this paper we present two schemes which will contribute to the optimal provision of service facilities by easing the financial constraint facing the land developers and suppliers of the facilities. The first scheme involves channeling a fraction of profits from a land development project and of the proceeds of mandatory sales of Type II National Housing Bonds as a loan to the suppliers of the service facilities. The second scheme considers the participation of the private sector in the project as a member of a consortium comprising the Korea Land development Corporation, the National Housing Fund, and private developers. It is proved that each scheme is superior to the current system. as well as entailing a very small cost.

Vernacular embodies a culture and economy that are unique to one particular region at a given period, expressed in the lifestyles of the ordinary people of the region. This study aims at interpreting Korean Vernacular Landscape by applying the analytical tool thus developed to the lifestyles of ordinary people found in their permanent dwellings (e. g., villages). By so doing, this study hopes to contribute to building a framework with which to understand the tradition of ordinary people by exploring the uniqueness and basic characteristics of Korean Vernacular Landscape. This study relies primarily on filed studies on, and publications relating to, the agrarian and residential landscapes. The Korean vernacular landscape has not only crude and simple generality, but also individuality derived from cultural circumstances and natural feature. Korean Vernacular Landscape may be characterized as the practical Vernacular Landscape, consisting of the raw materials that were only available in a particular region, shaped by the terrain, and maintained by the customs that varied from a region to a region.

Unconventional with respect for tradition: The Karel Doorman building stands in the heart of Rotterdam's shopping area and is a remarkable combination of restoration and new development. On top of the Ter Meulen shopping centre - a monument of the post-war reconstruction period - we have built an extremely light-weight construction in steel and wood (See Figure 1 & 2). This unconventional building method - at least in the Netherlands - enabled the construction of a 70 metres high 'glass' residential building with 114 apartments and 156 parking places. In this way a remarkable historic Rotterdam building was preserved for the future while at the same time new housing was created on a sheer impossible location, contributing to the quality of life and social safety in this part of the city.
