Residual performance of old architectural wood which has been damaged was measured using Nondestructive Evaluation (NDE). The wood Pole Tester was used to assess ultrasonic velocity inside wood and drill resistance was determined using an IML-resistograph. For ultrasonic measurements squared timber and circular timber's measurements were separately conducted with 1,300 m/s as the standard ultrasonic velocity. The standard wood samples divided into two parts; a non-sound area (below the standard), and a sound area (above the standard). Furthermore, schematization of wood was compared with results naked eye observation. The drilling resistance test was performed for both length and thickness direction in wood. The internal of the drilling was set at 30 cm (length direction), 5 cm (width direction) and 30cm (thickness direction). A non-sound area was defined as that 1) amplitude is below 20% and 2) carbonization and deterioration are related.

본 연구에서는 강우가 공간적으로 균질하며 아울러 그 공간상관구조도 지수함수를 따른다고 가정하여 남한강 유역의 강우관측망을 평가하였고 아울러 WMO의 기준과 비교하였다. 그 결과를 정리하면 다음과 같다. (1) 남한강유역은 WMO의 기준으로 볼 때 산지도 평지도 아닌 중간적 특성을 나타낸다. 그러나 남한강 상류부에서 관측된강우의 공간상관거리는 남한강 하류부에서 관측된 강우의 공간상관거리에 비해 짧게 나타나며 따라서 상류부와 하류부는 그 강우특성이 구별된다. (2) 남한강 유역의 강우관측망을 평가하는 기준은 대략 상위 50% 정도를 대표하는 상관거리 수준이 되어야 할 것으로 보이며 이 경우 적절한 우량계 사이의 거리는 상류부와 하류부 각각 18.2km와 21.1km로 추정된다. 단순히 강우계의 밀도를 평가할 때 남한강의 경우는 WMO의 산지기준을 초과하는 수준이다. (3) 남한강 유역의 우량계 분포를 검토한 결과, 특히 WMO의 온대지역 산지기준을 적용한 결과 우랑계의 공간분포가 적절하지 않음을 파악할 수 있었다. 그러나 본 연구에서 제안하는 상위 50% 정도를 대표하는 상관거리를 이용하는 경우에는 대략 5 - 6 지점 정도의 우량계 신설이 필요한 것으로 나타났다.

The road traffic noise has emerged major noise as the overcrowding of the urban population and the explosion of car storage capacity. There are limits for establishing the measures to meet noise standard because of the increase of high-rise building and insufficient distance between residential areas and road in urban center areas. Therefore, this study analyze the problem of the application of national road noise standard, and present the alternatives to achieve environmental standards in conjunction with the soundproofing measures. To reduce the population ratio exposed to road noise on seoul motorway, we suggest some action plane are as follows: i) Roadside noise standard of nighttime beside daytime is the first noise reduction goals ii) Noise standard of Noise and vibration control act is priority in case of existing area iii) Noise standard of basic environmental policy act is priority in case of new area.

This research is to determine the level of environmental pollution at a blasting construction area which is the origin of noise, vibration, and suspended particle, and to compare the results with other domestic and international standard data. This experiment is also to find out the effects resulting from blasting construction and to propose a plan that can decrease environmental pollution. The blasting construction area is a factory site which is about one and half million square meter and sewage disposal plant is about ninety thousand square meter. Both were selected as the areas for the tests to be conducted in determination test. The test to determine the level of noise, vibration, and total suspended particle was conducted thirty times around the blasting construction area by comparing measurement results and numerical analysis. However, as the test was not conducted in the laboratory but in the actual blasting construction area, it was not possible to do the test with the same exact conditions each true. Therefore, the test was not ideal as conditions could change from test to test. For the most part, the level of noise was below the standard level of 70dB. Every vibration test was under the standard limitation. For example, a house, 200m away was tested for noise and vibration and the level was found to be under the 0.2 cm/sec which is the standard for specialty designed cultural sites., i.e very low level. Also a buried oil pipeline that was 30m away also marked under 2.0cm/sec which is the norm for an industrial area. However, if there were an oil pipeline under the house, the amount of charging gunpowder per hole should be decreased compared to the amount used in the test. The test result for suspended particles under the standard limitation which is 24hour average 300$\mu\textrm{g}$/㎥ at a distance from blasting wavelength, but at detonator, total suspended particle from the blast origin exceeded the standard limitation. If explosion occurs when it detonates in the hole, most of the energy would be absorbed in the crushing of rocks, but some remaining energy would make noises and vibration inevitable. So the important thing is how to minimize the environmental pollution from the blasting. There should be regulations in order that the standard limitation is not exceeded, and to decrease the environmental pollution from the blasting.

The purpose of this study is to examinethe present illumination conditions in office environment and to suggest an efficient illumination plan in office planning process. Illumination conditions in work environment were surveyed in 6 offices to investigate whether the present illumination conditions were appropriate to the work type. The results of this study are as follows: Most of the general Illuminance level in the area of work were all at an adequate level, except one. The average Illuminance level in the all meeting rooms were met for the standard. Illuminance in the all reception area were extremely over the standard, The illuminations of this area were rather designed according to the image of the company than the standard. As for the illumination method in the area of general work, four offices used a general lighting by a direct lighting type, while two offices used a general lighting and a task lighting at the same time. This survey suggested that first, each company should consider illumination plan in the building planning process, second, illumination plan considering the type of places is needed, and third, illumination environment may be differentiated according to the work type. In conclusion, efficient illumination environment should be considered in office building planning process, especially In terms of illumination materials and methods.

SPM, which is an abbreviation of Single Point Mooring, also called as SBM(Single Buoy Mooring), is a special buoy besides the quays of the harbor for mooring ships, and is normally a 3m wide cone or cylinder shaped steel drum fixed underwater so it won't move, and is used for mooring cargo-work at outer port by laid-up ships and large crude oil carrier. The work of VLCC SPM mainly is accomplished on the open sea. On the open sea as a result of meteorological condition and the ocean wave influence, When the weather condition is get bed, peremptorily moving to the safety place, because of the gale and the billow, almost happened frequently, the pilot is unable to go on board and the tug is also unable to be used Now because of the bad weather the VLCC SPM moving to the other safety place frequently happened in the ulsan port. the construction of new harbor, it constructed many break water around SPM. So that it is necessary to propose the new standard about how to maneuvering area actually. The standard for handling ranges of the SPM operations was tested and verified by a simulation.. So that it is necessary to propose the new standard about how to maneuvering area actually.

This paper aims to suggest ways of institutionally improving standards that must be applied when installing Water Reclamation/Reuse (WRR) system based on efficiency analysis. Currently, the standard for WRR system establishment requires that the system should treat more than 10% of used water in the building of over $60,000m^2$ in total area of all floors, but our research has found that it would be more effective to change the standard to $150-m^3-per-day$ reclaimed water or the total area of all floors of $30,000m^2$ ($50,000m^2$ in the case of an office building). In other words, what this paper suggests is not a one-size-fits-all standard based on the total area of all floors, but a reasonable and flexible standard that takes into account efficiency and a unit water usage according to a building's purpose. Furthermore, this paper recommends a new WRR standard that can be applied to large-scale land development for housinglots, like the New Town. The recommendation is based on the economic analysis that the WRR system will ensure efficiency only if the amount of reclaimed water is over 4,000 tons per day, which corresponds to 4 millions square meters of housinglots. Regarding the size of the established facility, this paper suggests changing the standard, which is now set at over 10% of water usage, to what is relative to the total amount of use of reclaimed water in order to ensure efficiency and promote use of reclaimed water. In addition, this paper proposes that governmental support should be offered not only to facility owners, who are recipients at present, but also to facility builders. By doing so, those who donate a facility to the government, central or local, after building it, can be provided with substantial aid. Therefore, the application of the institutional improvement suggested in this paper is expected to create environment-friendly living conditions and boost the quality of life by encouraging people to secure water resources efficiently in buildings, and in a wider range, in cities.
