The interactions of various carcinogens, such as polyaromatic hydrocarbons, dimethylaminoazobenzene(DAB) and its derivatives and benzacridines with deoxyribonucleic acid(DNA) were investigated by means of second-order perturbation method. The most probable orientations of molecular complex between DNA-base pairs and carcinogen were defermined by the quantity of charge transfer from adenine-thymine pair (A=T pair) to carcinogen and from Guanine-Cytosine pair (G≡C) to carcinogen. It was found that the quantity of charge transfer from thymine part of A=T pair to carcinogen was considerably larger than that from guanine part of G≡C pair to carcinogen. A good parallelism was alos found between the quantity of charge transfer and experimenental carcinogenic activity.

The interactions of chemical carcinogens, such as polycyclic aromatic hydrocarbons, dimethylaminoazobenzene (DAB) and its derivatives and heterocyclic compounds with tissue components, especially with deoxyribonucleic acid (DNA), were examined by means of simple Huckel method. Assuming that the formations of a loose molecular complex between the carcinogens and the tissue components are the first step of chemical carcinogenesis, the most proble orientation between the chemical carcinogens and adenine-thymine (A=T) pair or guanine-cytosine $(G\equivC)$ pair is determined. It has been found that, in the case of the formation of molecular complex between chemical carcinogens and A=T pair, the two atoms of K-region of the carcinogens and the atom of L-region in the proximity of their K-region are combined correspondingly with C-l' carbon atom in the sugar that is attached to thymine, N-1 nitrogen atom and C-5 carbon atom in the thymine part of A=T pair, while, in the case of that between the carcinogens and $G\equivC$ pair, the above three atoms of the carcinogens are combined correspondingly with C-8 carbon atom, N-9 nitrogen atom and N-3 nitrogen atom in the guanine part of $G\equivC$ pair. 發癌物質과 DNA 鹽基雙間의 分子錯物形成에서 可能性있는 配置(orientation)를 決定하였다. 아데닌-티민 염기쌍에서는 티민쪽에서, 구아닌-시토신 염기쌍에서는 구아닌쪽에서 分子錯物을 形成한다.

In this paper, a robust control scheme of a nonlinear system with norm bounded uncertainty is studied. The proposed algorithm is based on variable structure systems (VSS) theory. the sliding mode which is robust to plant uncertainty and disturbances is obtained by regulating a sliding surface equation. This VSS control law can improve the robustness of control systems by adjusting the minimum reaching velocity in a reaching phase. A numerical example is given to verify the effectiveness of the control law.

Unusual kinetic behavior was observed in the substitutions of hemin with imidazole and cyanide ion under conditions of [L] S 2[hemin] (L=substituting ligand) in N,N--dimethylformamide. The rates of these reactions were much slower than those the formations of mono- and bis-coordinate complexes. Based on the kinetic results, these slow reactions were interpreted in terms of the dissociations of mono-coordinate complex to solvated hemin. The activation volume was determined to be 24.3 -- 0.4 cm3 mol'1 for the reaction with imidazole by the high pressure stopped flow method. The large positive value of the activation volume strongly supports a limiting dissociative mechanism.
2.75인치 로켓 발사관의 페어링 장착이 로켓 후출 비산물의 비산범위에 미치는 영향성 연구

2.75인치 로켓탄은 1940년대에 미해군 병기시험국(NOTS, Naval Ordnance Test Station)에 의해 개발되어 오늘날까지 공대공 또는 공대지 무유도 미사일로써 광범위하게 사용되고 있다. 2.75인치 로켓탄은 다양한 종류의 탄두를 로켓모터와 결합하여 사용하는데, 로켓의 형식(designation)은 탄두의 종류와 상관없이 로켓모터에 의해 구분되어진다. 한국 육군은 2.75인치 로켓탄(2.75 inch FFAR, Folding-Fin Aircraft Rocket)을 운용하고 있는데, 500MD 헬기에서 사격훈련을 실시하는 중에 로켓모터(KMK40A)의 후방 비산물로 인해 항공기 동체 손상 등의 문제점이 보고되었다. 따라서, 본 연구에서는 2.75인치 로켓탄 발사 시 비산물로 인한 항공기 손상을 방지하기 위한 방안으로, 발사관 후방 페어링(Fairing) 장착의 효과성을 확인하고자 하였다. 지상연소시험을 통하여 항공기에 손상을 줄 수 있는 주요 비산물로 접촉원판, 날개지지판 및 접촉원판과 날개지지판의 결합체임을 확인하였으며, 2.75인치 로켓 발사관(Launcher) 후방에 페어링 미장착, 상용페어링 장착 그리고 상용페어링 대비 길이가 2배로 특수제작된 페어링 장착상태에서 지상발사시험을 실시하여 각각의 경우 비산물의 비산각을 확인한 결과 페어링을 따라서 추력의 흐름이 형성되는 것으로 추정되었으며 따라서 페어링의 길이에 따라서 비산물 비산각도가 감소하는 것을 확인할 수 있었다.

Attempts have been made to use Supercritical fluids for industrial purpose in a variety of fields and some of them, are already in practice. However, basic chemical properties of supercritical fluids have not been understood well. The present paper presents the results of physicochemical studies on Supercritical fluids as well as the application of supercritical fluids to industry. The detail is as follows PCB and organic compounds.

For the destruction of toxic chlorinated organic compounds, this study proposes improved supercritical water oxidation method (multistep oxidation) using sodium nitrate as an oxidizer. This method solves the problems involved in the existing supercritical water oxidation method. Multistep oxidation means that NaNO₃ is oxidized to N₂ via NaNO₂ and NO. Toxic and hard to destroy organic substances like para-dichlorobenzen(4-DCBz), polychlorinate biphenyl(PCB) ware oxidized to non toxic substances in a condition, in which rapid pressure and temperature rise is restrained as much as possible. 4-dichlorobenzene(4-DCBz) and Polychlorinate biphenyl(PCB) in condition(450℃, p_(w)=0.25g/cm³, 30min) Was discomposed perfectly.
