This study is to consider the introduction of the standard practice which test the asbestos stabilizer efficiency for the spray-applied ACBM, because asbestos stabilizer may be one of operation & management (O&M) program to prevent friable asbestos from spray-applied asbestos containing building materials( ACBM) and some countries like U.S and Japan have introduced the evaluation system or standard practice to test the efficiency of asbestos stabilizer which is used for spray-applied ACBM since 2002 and 2006, relatively. Efficiency test of 8 stabilizers which were manufactured from Japan, Australia and Korea was performed by the method of the Ministry of Land, Infrastructure, Transport and Tourism of Japan. The contents of test method were consisted adhesive strength, penetration depth, impact resistance and wind affection. The efficiency of impact resistance and wind affection was improved 4.1～37.4% and 75.2～95.7% after asbestos stabilizer applied on the spray-applied ACBM. Although the results of adhesive strength were less than that of non-applied materials but that was satisfied the ASTM standard (2.4kPa).

A greening phenomenon has been observed in some plant foods such as chestnut, sweet potato,burdock, and others during processing. The formation of the pigments was postulated as reactions of primary amino compounds with chlorogenic acid or caffeic acid ester, yielding acridine derivatives. Acridine derivatives have been regarded as mutagenetic agents. For the reason, the bacterial reverse mutation test was carried out to evaluate the genotoxicity of green pigment using Salmonella typhimurium TA98 and TA100. Alanine, arginine, aspartic acid, glycine,lysine, and phenylalanine were reacted repectively with chlorogenic acid to synthesize model compound. Green pigment was extracted from sweet potato. Maximum concentration of 2 and 50 mg/plate was tested for the synthetic green pigments and extracted green pigment respectively, taking bacterial survival, solubility, and color intensity into consideration. There was no signigicant increase in the reverse mutation either with or without S9 activation system by any test material. Though further studies with other genotoxicity test system are necessary, both synthetic and sweet potato green pigments seemed not to cause mutation despite the acridine moiety in their structures.

미치는 영향을 조사하기 위하여, 중금속이 오염된 토양에 토마토를 심고, 뿌리 혹선충의 알을 접종한 후 토마토의 생육상과 뿌리혹선충의 밀도를 조사하였다. 실 험에 사용된 토양은 Cd은 3.0~10.6(mg/kg), Pb은 128.6~339.0(mg/kg), Zn은 123.7~262.19(mg/kg)이 농축되어 있으며, 농경지의 중금속 기준 농축량 높았다. 중금속이 오염된 토마토 지상부의 평균 높이와 무게는 각각 19.5cm와 3.6g 이었으 며, 중금속이 오염되지 않은 토양에서 자란 토마토의 평균 키와 무게는 51.9cm와 12.5g이었다. 토마토의 키는 신뢰한계 99%에서 통계적으로 유의성을 보였으나, 무게는 편차가 커서 유의성을 보이지 않았다. 중금속이 오염된 토양에서 자란 토 마토 뿌리의 평균 길이와 무게는 각각 5.9cm와 4.3g이었으며, 오염되지 않은 토양 에서 자란 토마토 뿌리의 평균 길이와 무게는 각각 15.0cm와 8.1g이었다. 뿌리의 길이는 99% 신뢰수준에서 통계적으로 유의성을 보였으나, 무게는 유의성이 없었 다. 뿌리혹선충에 의한 토마토 뿌리의 gall index는 오염토양이 1.3이었으며, 오염 되지 않은 토양의 gall index는 4.3으로 오염되지 않은 토양에서 자란 토마토가 뿌 리혹선충의 혹이 더욱 많았으며, 통계적으로 차이를 보였다. 선충의 밀도는 유의 성이 없었다. 중금속이 토양내에서 농도가 높을 수록 토마토의 생육과는 음의 상 관관계를 보이며, 특히 Pb은 상관계수가 -0.62로 높았다. 또한 식물기생선충인 뿌 리혹선충(Meloidogyne incognita)에 의한 혹형성과 토양내 중금속의 농도에 대한 상관계수도 -0.62로 높았다. 중금속이 토양내 고농도로 축적되어 있으면, 토마토 의 생육에 영향을 주고, 생육중 시들음 증상이 증가하며, 식물기생선충인 뿌리혹 선충의 활동에도 영향을 주는 것으로 조사되었다.

The result showed that the ratio of EDI (estimated daily intake) to ADI (acceptable daily intake) was 0.000007~0.458% which means that the detected pesticide residues were in a safe range so that residual pesticides in the agricultural products in Korea.

구면조화함수 조명 기법은 실시간 환경에서 전역 조명을 나들고, 다시 비추거나, 화면에 나타내기 위해, 광원으로부터 3D 모델에서 빛을 계산하는 기술이다. 이 기술은 메모리에 미리 계산해 놓고 적분을 내적에 의해 단순하고 빠르게 수행함으로써 비용이 많이 드는 렌더링을 간단하게 해주기 때문에 PRT(Precomputed Radiance Transfer)라고 불려진다. 본 논문에서는 간단한 베이시스 함수인 르장드르 다항식과 체비체브 다항식을 이용함으로써 구면 조화의 한 종류를 표현하는 방법을 제안한다. 실험을 통해서 르장드르 다항식의 경우에는 베이시스 함수가 함수의 수가 적다면 부장드 르 다항식보다 더 나은 성능을 나따내며 전처리 렌더링 시간을 줄일 수 있다는 것을 확인했다.

본 연구는 광릉 지역의 활엽수 천연림과 도로 주변에서 서식지 구조와 조류군집의 특성을 파악하기 위해 2005년 10월부터 2006년 8월 사이의 기간 동안 수행되었다. 활엽수 천연림과 도로 지역의 서식지 환경은 매우 큰 차이가 있는 것으로 나타났다. 활엽수 천연림은 대경목의 비율이 높고 상층 임관이 잘 발달해 있는 반면, 도로에서는 소경목이 대부분을 차지하였으며, 상층임관의 발달이 적은 반면 하층식생의 피도가 높았다. 계절별 조사 결과 활엽수 천연림에서는 모두 37종의 조류가 관찰되었으며, 도로에서는 20종이 기록되었다. 4계절에 있어서도 활엽수 천연림 이 도로보다 관찰 종수, 개체수 및 종다양도에 있어서 모두 높은 것으로 나타났다. 또한 길드 구조에 있어서도 활엽수 천연림 지역에서는 수관층 및 수동(나무구멍)에서 먹이와 둥지를 얻는 조류들이 많이 관찰되었으며, 도로에서는 관목이나 지면을 이용하는 조류가 많이 기록되었다. 두 지 역은 인접해 있음에도 불구하고 조류 군집의 특성에 있어서 큰 차이를 보였다. 이러한 차이는 두 지 역 간 서식환경의 차이와 깊은 연관이 있는 것으로 판단된다.

The cable staying roof structure of Jeju worldcup stadium should be erected with correct prestressed force that is required by the structural engineer who designs this structure. This study evaluated and adapted the erection process of cable, the erection force and the measurement of cable force for Jeju worldcup stadium. The process of erection is required not only to calculate erection force but also to check structural stability, following process, construction period and using cranes. Considering the site conditions and technical problems, this study can attain successfully the erection of cable staying roof structure of Jeju worldcup stadium with allowable errors.

Construction of roof structure, cable suspended structure, for Pusan main stadium is adapted a lifting method that is VSL lifting system. 5 processes are practiced for erection of the roof structure including the first lifting process for erection of upper cables and the second lifting process for erection of lower cables. Since all cables of this roof structure with two open spelter sockets are determined their length, some cable were wrong length, he roof structure would be unstable. But, At complete of erection for the roof structure each cable is attained to theoretical tension force with average 4% errors.

This paper describes three modules for development of the Space Frame Integrated Design System(SFIDS). The Control Module is implemented to control the developed system. The Model Generation Module based on PATRAN user interface enables users to generate a complicated finite element model for space frame structures. The Optimum Design Module base on a branch of combinatorial optimization techniques which can realize the optimization of a structure having a large number of members designs optimum members of a space frame after evaluating analysis results. The Control Module and the Model Generation Module Is implemented by PATRAN Command Language(PCL) while C++ language is used in the Optimum Design Module. The core of the system is PATRAN database, in which the Model Generation Module creates information of a finite element model. Then, PATRAN creates Input files needed for the analysis program from the information of the finite element model in the database, and in turn, imports output results of analysis program to the database. Finally, the Optimum Design Module processes member grouping of a space frame based on the output results, and performs optimal member selection of a space frame. This process is repeated until the desired optimum structural members are obtained.
