This study was carried out to remove copper ion in case of activated carbon impregnated sulphur(ACS) dose and different pH using activated carbon impregnated sulphur that prepared from activated carbon at sulphur dioxide atmosphere. Removal copper ion concentration was increased as increasing the ACS dose when copper ion concentration was 10 mg/L. Optimum dose of ACS 13.3 g ACS/L and maximum removal efficiency was 93%. The results obtained from adsorption experiment in the condition of ACS optimum dose when the pH was 3, 4, 5 respectively was pH 5 was excellent.

본 연구는 현재 급속히 확산되고 있는 대형 할인점의 지하 매장에 대한 피난성능 개선방안을 제시하기 위한 것으로 주요 내용은 다음과 같다. ·할인매장의 건축적 공간 특성 및 피난 상 문제점 분석 ·지하매장의 거주밀도 분포 조사 ·피난용량 적정성 검토를 위한 피난 시물레이션 연구 결과, 매장의 실질적인 수용인원을 기준으로 적정피난용량을 결정해야 하며, 피난동선상에 있는 임시 판매대, 쇼핑 카트, 그리고 피난층의 계산대가 피난에 중요한 쟁애요소로서 이에 대한 개선과 제도적 정비가 필요함을 알 수 있었다. 피난시간을 기준 한 성능기준 피난설계 분석결과, 사례분석 대상 지하매장은 적정피난용량을 확보하지 못하고 있음을 보여주었다. This study aims to improve the Evacuation Performance of the Discount-store in underground that is rapidly growing new shopping store in Korea. In this paper, The architectural properties of the floor plan and section was reviewed with egress focus, occupant load density of the Discount-store was surveyed and the procedure and method of performance based egress design for this occupancy was analysed with SIMULEX model and calculation method. As a result of modeling, mire longer svsilable safe egress time (ASET) is expected than required safe egress time (RSET) in underground discount-store. In order of improve the Evacuation Performance for this based on occupant load density and review of shopping cart's structure and size and maximum escape capacity of the cash counter.

Spent pig bone was consist of hydroxyapatite. And then we thought that it have a possibility as a adsorbent. The preparation of bone char prepared from spent pig bone in this study. We study on the recycling possibility as a adsorbent is able to adsorb copper ion from their single aqueous solutions. The results are summarized as follows. Bone char that prepared from spent pig bone at 105, 400, 700℃. The adsorption removal efficiency of copper ion onto bone char as adsorbent was above 90% for 15 hours. Increase in the initial pH of the copper ion solution result in an increase in the copper ion uptake per unit weight of the adsorbent. Freundlich isotherm model was found to be applicable for the experiment data of copper ion. The results showed that spent pig bone can be used for the absorption of the copper ion.

본 연구는 팩시밀리의 주기판(main board)을 기능적으로 테스트하기 위해 구현한 FFTS(Functional Facsimile Test System)에 대한 기술이다. 본 연구의 목적은, 테스트시 수반되는 모든 작업을 자동화하고, 테스트 수행중 발생하는 여러가지 상태들을 자료화하는 것이다. 아울러 주기판에 대한 입출력 신호들의 종류와 그 특성들이 변경될 경우라도 소프트웨어의 수정만으로 그 것에 대처한 후 계속적으로 테스트를 수행할 수 있도록 한다. FFTS는 주기판에 접속되는 여러가지 장치들을 하드웨어적으로 에물레이션하며, 테스트용 전용언어, 그리고 그것에 대한 컴파일러를 포함한다. FFTS로 테스트를 수행하는 방법에는 대화식 모드(IAT)와 대화식 테스트에서 수행할 수 있는 모든 과정을 테스트용 언어로 저장한 후 그것을 반복하여 사용하는 배치 모드(Batch mode) 등이 있다. FFTS의 유용성을 실증하기 위해 여러 종류의 팩시밀리에 대하여 실험을 실시하였다. FFTS (Functional Facsimile Test System) is designed and implemented. It is possible to eliminate repeated test work and to analyze the data obtained through test. If the specification of the signals from/to main board of facsmile is changed, it is possible to cope with the change by modification of FFTS software. FFTS emulates the devices connected to the main board. FFTS is designed to test the main board either by using interactive(IAT) mode with graphic user interface or by using noninteractive(NIAT) mode with test command file which is coded manually or created from IAT mode. The operation of the FITS is verified for several types of main board of G3 class facsmiles.

This study was conducted to develope elite, high adaptable corn hybrids using alien germplasm. We investigated yields, plant characters, and yield components of new 6 hybrids and 4 check hybrids. Hybrid CIM.A-21 × NC 246 which was late for days to tasseling, high for plant and ear heights showed the highest grain, stover, and total dry matter yields. Hybrid KS 8 × SC 12 which was a little lower total dry matter yield showed relatively high grain yield, early flowering, and good characters for plant and ear height. Horizontal plant type hybrids with big leaf angle had small leaf area index, were early matured varieties and high in yields. In yield components, KS 8 × SC 12, Suwon 19, and KS 7 × SC 12 were higher than the other hybrids. KS 8 × SC 12 might be the most effective material to develope corn hybrid. Leaf angle showed negative correlation coefficients with all of the characteristics of corn hybrid, except for ear height, stem diameter, and weight of 100 kernel. Expecially, it had negative correlation coefficients with plant height and number of kernels per row in 5% levels, and with grain yield, total dry matter in 1% levels.

Carbosulfan의 피부자극성, 안점막 자극성 및 피부감작성등의 알러지성 효과에 관한 연구

Many studies have been published on the human health effects of carbosulfan toxicity. Carbosulfan used as an insecticide can produce an irritating and allergenic effect when acting on the skin. In this study, a sensitization test on albino guinea pigs and intradermal reactivity and occular irritation test on albino rabbits were carried out with carbosulfan. Signs of acute skin inflammation appeared along with the clinical symptom of chronic dermatosis caused by the solution irritating characteristics. Moreover, carbosulfan showed severe eye irritation with conjuctival redness and severe opacity on cornea. Preventive measures should involve workers' obligatory instructions on the noxious impact on human skin and strict observance of industrial safety rules.
