  • Objective : To present a criteria for acupuncture standardization, which will improve quality of acupuncture and secure safety, through studies of the biocompatibility of acupuncture. Methods : The acupunctures distributed in Korea were studied. The chemical composition, elasticity, and the solidity of the acupuncture's metal material was analyzed. Results & Conclusions : 1) The acupunctures distributed in Korea were all produced with ST304. Because acupuncture is used on a living body, the corrosion resistance, allergy proof and magnetism of the metal material should be considered. In this point, STS316 stainless steel would be more suitable than ST304. 2) The elasticity and solidity of the acupuncture's metal material distributed in Korea meet the medical instrument standards of the Korea Food and Drug Administration. But since the standards are only roughly outlined, the criteria should be realized and standardized.

  • 2013년 국토교통부에서는 현 정부의 주요 국정과제인 행복주택 사업의 일부를 모듈러건축 시스템으로 시범공급하겠다라고 밝혔다. 이처럼 모듈러 건축에 대한 정부의 적극적인 의지와 함께 모듈러 건축시장의 규모도 점차 확대되고 있다. 현재 모듈러건축의 주요 문제점으로 설계-제작단계에 있어 자재 및 부품의 표준화 또는 규격화 미비가 거론된다. 이때, 모듈러건축은 기존의 타공법에 비해 재료비의 비중이 16~17% 높은, 전체공사비의 60%를 차지 할 정도로 자재관리가 중요하다고 판단된다. 하지만, 설계상의 표준화 또는 규격화의 미비로 제작단계의 자재 손실율이 높아지게 되고, 이에 따른 건설폐기물 뿐만 아니라, 재료비 증가에 따른 전체 공사비도 증가하게 된다. 본 연구에서는 벽체 마감자재 중 석고보드 자재에 대한 손실율을 최소화 할 수 있는 최적화 알고리즘을 개발하여 대상 사례의 주요 모듈에 대해 검증하고자 한다. 이를 통해, 자재의 낭비적인 요소를 최소화하여 친환경 건축에 기여할 뿐만 아니라, 현 모듈러건축의 단점으로 인지되고 있는 고비용의 경제성 문제를 해소하는데 기여할 수 있을 것으로 기대한다.

  • In this study, we processed two procedures of application test of filler for special-purpose utility that are new application methods of aerated concrete and properties test of aerated concrete according to mixing ratio because we investigated the better use of aerated concrete as filler for fireproof safety and we proposed basic data about standardization of mixing of aerated concrete. We measured flow and volume change of aerated concrete. And if its volume doesn't change, we added measuring unit weight and compressive strength. To test application of aerated concrete as filler for fireproof safety, we filled up aerated concrete to fireproof safety according to suitable mixing ratio. Then we measured maximum temperature of inner part of fireproof safety in accordance with the standard test of fireproof. According to the results, aerated concrete as filler for fireproof safety could be possibly used. So when we make aerated concrete, we should consider using an adding agent as well as a foaming agent.

  • A comparison of the analytical data obtained by three $k_0$-NAA software programs was carried out using both the airborne particulate matter collected from an urban site and the certified reference materials of the air filter and urban dust to evaluate the performance of the analysis. The individual $k_0$-NAA standardization methods of three countries, Korea, China and Vietnam which had been modified from the well established $k_0$-program were used for the comparative analysis. The measured concentrations of 30 elements from the two kinds of air samples based on this software were in agreement with each other within about 20% analytical error except for a few elements. By contrast, the results of China and Vietnam were moderately higher than that of Korea due to a systematic error associated with the detection efficiency, gamma peak analysis and geometric effect.

  • This Research was the standardization of nutrient sources by reviewing the possibility of cultivation and analysis of imported nutrient sources used in Pleurotus ostreatus culture. As a first result, the concentration of heavy metals was not detected or trace, and the total nitrogen content of cotton seed pomace was 6.22% in Australia, which was higher than that of Chinese or USA. As a second result of physical properties of nutrient sources, the water holding capacity of beet pulp from Egypt was higher with increasing pressure. The volume water content of US was highest at 400hpa and 500hpa in case of cottonseed meal. Third, the content of total nitrogen was the highest at pH 5.51 and the total nitrogen content was the highest at 2.45, and the C/N ratio was the highest at 28.18. Last result shows that first germination day, yield and biological effciency of all treatments were not significant differnet except T2. These results shows that australian cootton was inappropriate to Pleurotus ostreatus culture. Nevertheless, the safety and standardization of the Pleurotus ostreatus culture medium should be assured by reviewing the media low material importing season, mushroom yield and nutrient sources.

  • The use of non-bearing light weight wall has increased recently due to the increase of high-rise buildings and supply of long-life housing. Light weight wall has advantages such as reducing the self-weight of the building, convenience in installation, and shortening construction period, however, must have a sufficient strength to external force. This study standardized the impact resistance test method for light weight walls by using the actual impact load obtained through load analysis test in previous studies. The impact resistance test method was divided into the test method that uses soft body and the one that uses hard body. The size of specimen was set up as height 2.4m and width 3.0m. The size and shape of the body followed those used in BS 5234-2 and so on for the compatibility with the test method used overseas. The judgment criteria for impact resistance based on test results were not defined uniformly as the assessment of functional damage can vary depending on the type of material, structural method, purpose of wall, and so on even when the same impact load was applied.

  • The use of non-bearing lightweight wall has increased recently due to the increase of high-rise buildings and supply of long-life housing. Lightweight wall has advantages such as reducing the self-weight of the building, convenience in installation, and shortening construction period, however, must have a sufficient strength to external force. This study standardized the stiffness (static horizontal load resistance) test method for lightweight walls by using the actual impact load obtained through the load analysis test conducted in the previous studies. The size of specimen was set up as height 2.4m and width 3.0m. Test apparatus and test methods were referred to BS 5234-2:1992. However, the loading level applied to the specimen was divided into 3 steps (3000N, 1000N, 500N) that can be applied selectively depending on the purpose of the wall. The deformation characteristics according to the same loading level were vary depending on the specimen's type, and the evaluation criteria for functional damage may vary depending on the material, method of construction, and purpose of wall. Therefore, we did not suggest unified evaluation criteria of the stiffness to the test results.

  • Glass melting process is influenced by both control and observation factors, where control factors include quantity and mixing ratio of raw material, the amount of fuel and air in-take. Further observation factors include temperature and pressure at each step of process inside glass melting furnace. Ambient Control is an effective means to eliminate complications from excessive variation among raw materials, or external disturbance from wide fluctuation of environment around equipments. Ambient Control uses both control and observation factors mentioned above. This study suggests an effective Proactive Control System that can enable genuine 4M standardization in glass melting furnace by applying Ambient Control.
