The Storm Water Management Model(SWMM) by EPA is a dynamic rainwater-runoff simulation model used for single event or long-term simulation of runoff quantity and quality from primarily urban areas. The SWMM simulation program is operated by the site area, the weather date, conduit plan etc. on reference region. The purpose of this study was to analyze flood area, the duration of flooded and surcharged on the reference region. Without rainwater stored tank, the area of flooded and surcharged on reference area is similar to the area of reference region. But, With rainwater stored tank, the area of flooded and surcharged on reference area is much reduced compared to without rainwater stored tank. According to SWMM simulation results, the rainwater stored tank is located closer to site is more effective for reduction of duration of flooded and surcharged and flow rate.

This paper proposes and evaluates a scheme which enhances real-time performance on the Ethernet-based residential network where cable length is very short and most of traffic passes through a specific device. The scheme aims at enhancing deadline meet ratio of the real-time traffic, for example, video stream by means of applying the functionalities such as queue discrimination and early packet discard as well as maintaining network load properly. The design includes the description on hardware interfaces along with the software modules such as scheduler, device driver and connection manager. The simulation results via SMPL suggest that the proposed network can be used as a cost-effective residential network. We also measure the permissible bandwidth for non-real-time traffic without degrading the performance of real-time traffic.

1960년 이후 급속한 경제성장과 산업화에 따라 도시의 인구 집중과 핵가족화 현상으로 주택에 대한 수요가 증가하자 공동주택을 짧은 기간에 대량으로 공급하지 않을 수 없게 되었다. 이 결과 1995년 국내 통계에 의하면 도시주택 유형 중 아파트가 48.1%를 차지할 만큼 대표적인 공동주거 형태로 자리잡게 되었으며 가용택지의 부족은 이후로도 단독주택보다 아파트와 같은 공동주택 건설의 중대를 야기할 것으로 예상된다.

The aim of this study is to discuss ways to improve Korea's housing survey by comparatively analyzing the housing surveys being carried out in six other countries. The subject countries are the United States, the United Kingdom, France, the Netherlands, Australia, and Japan-the countries that conducts large-scale surveys for more than 20,000 households on a national level and where data collection is easily available. The comparative analysis items include survey history, purpose, subject, project owner, survey item, data collection method, and the use of survey outcome. The comparative analysis results showed that each of the six countries are conducting national housing condition surveys on a regular basis considering each nation's characteristics of housing stock and policy goals, and the survey results are being used as the basis for setting policy guidelines including the selection of policy targets and the determination of appropriate rent standards, and the basis for housing assistance budget planning. Korea's housing survey has been conducted three times up until now since 2006. There should be efforts to systemize and standardize the survey components, establish standards for monitoring the changing trend of national housing stock, standards for determining policy targets, and measures to open data and provide feedback considering the preceding studies of overseas countries in order to better utilize the housing survey data for policy development.

The law on promoting rationalization of mansion management is the one that was enacted with the aim of enhancing stability of people's life and further of promoting sound development in national economy, by securing good residential environment of mansion in Japan. A rise in mansion, the distinct characteristics of a residential form that only mansion has, and the insufficiency of legal modification related to this are the issues that have been steadily proposed in academic circles and practical affairs in Japan. Also, in the managerial aspect, even problems about the operation of the management association, the maintenance & repair, the management contract on management agency in management association, and the correct transfer of design completion plan have been pointed out. To solve these problems, the law of rationalization was legislated. However, the law of rationalization can be ultimately evaluated to suggest its solution on a problem about forming agreement on mansion management. On the other hand, it is concerned about the management association and section owner in mansion, and about mansion that was progressed aging considerably. For example, it is proposing or suggesting duties in several forms caused by dwellers' diversity to local self-government. Thus, it is a fact that a number of difficulties exist in smoothly enforcing the law of rationalization.

The multifamily housing has various advantages in construction cost, land-use intensity. KRIHS(1997) recommended the proper scale of th multifamily housing as 800 households in constructability, 1,000 households in facility compactability, 500 households in social aspect. At the early planning stage of project, the size of the multiftmily housing has, until now, been maximizingly considered under the regulation on which has been emphasized at the building volume ratio, land area, etc., except for the expenditure during the maintenance stage. This paper aimed at providing the proper size of multifamily housing in aspect of area and household number with maintenance cost at the early stage of project. For these, it took 곧 average cost function which is made from the 3-rd quardratic form and analyzes the unit increasing rate of the average cost. It surveyed in nationwide focused on the central heating system using diesel and kerosene. The number of samples is 88 and items of management cost is 11. The results are as follows ; first, 3rd-order quadratic function is proper at explaining the cost variation, considering the multicollinearity and statistics. Second, the proper size of multifamily housing is recommended with 83,000 $m^2$ on management area, 820 or over the 2,630 household number in aspect of total management cost.

In the design guideline about the existing elderly housing, the equipment related to bathroom are the most important in the secure and functional aspect. On the other hand, the present elderly housing is being designed according to foreign design guideline or common housing form instead of reflecting living and physical qualities of the Korean elderly. Therefore, in this study based on the guideline of the existing literature, we made Mockup furnished with the equipments of bathroom and conducted an experiment in finding proper position and height for Korean elderly enough to use the bathroom conveniently and independently. The equipments of bathroom consist of different height wash bowls, toilet stools, grab bars, and a bathtub. As a result, suitable height of wash bowl is 760 mm $\pm{\alpha}$. We can realized that elderly feel comfortable to grab perpendicular bars of toilet stools more than horizontal ones. So it is necessary for elderly to grip perpendicular of grab bars added to prevention slipping and made shape easy to hold. Most of elderly told us that 500 mm of the bathtub setting is suitable. But many other people feel high. So height of the bathtub must be established lower than 500 mm for safety in the bathroom and for convenience.

Korean Classical Music, as the abbreviated wording for 'Korean Music', is being used as the indicating phraseology for our traditional music that distinguishing from Western Music, the foreign music or foreign-styled popular music. Since such Korean Classical Music has the different acoustic characteristics from Western Music, it needs its own performance space for the special exclusive-use of Korean Classical Music. Likewise, even though the demand for the performance space of special exclusive-use for Korean Classical Music where Korean Classical Music is rendering, is on increasing tendency due to the increase of national concern about traditional culture art, since it is being planned without any concrete standard or method that gratifies the supreme listening condition, it is the real situation that a securement of the satisfying acoustic condition is very difficult, after the completion of construction. On such viewpoint, in order to evaluate the acoustic characteristics of the performance space of special exclusive-use for Korean Classical Music, based on the subjective response which reflects human being's psychological attribute at first, this Study has attempted to extract the proper evaluation vocabulary for appraisement on Korean Classical Music. The abstracted vocabulary in such way would be used significantly for Subjective Response Evaluation in order for the evaluation on the Acoustic Characteristics of the performance space of special exclusive-use for Korean Classical Music.
