This study in investigated differences between father's involvement Behavior perceived by their children which consisted of both qualitative and quantitative behavior and Father's gender role attitude in korea and Japan. The research sample consists of 240, 4-5th grade Korean children and their fathers and 215, 5-6th grade Japanese children and their fathers in Seoul and Tokyo respectively,. Results showed that (1) Korean fathers exhibited more affectionate child rearing behavior than Japanese fathers. On the other han Japanese father exhibited more father's involvement behavior than Korean fathers (2) Korean fathers tended to show more traditional gender role attitude than Japanese fathers do. (3) In the both countries father's affectionate child rearing behavior are greatly affected by non-traditional gender role attitude whereas father's involvement are affected by length of time the that fathers devot to child care.

Using acclimated sludges with inorganic nitrogen medium for three months and raw sludges, we investigated characteristics of biological nitrogen removal. As results, the acclimated sludges accomplished nitrification efficiently. But raw sludges have hardly done ammonium-nitrification and there was a increasing of ammonium concentration in flask with raw sludges for established experimental period of 72 hrs.

For research, the methodology of analysis of literature and case study on already established representative libraries was conducted. And the analysis on regional current circumstance to obtain standards of the representative library was conducted. As a results of this study a model of widely representative library building is presented regards on location, facilities and organization.

From the aerial parts of Saururus chinensis growing in Korea, four flavonoids (hyperin, isoquercitrin, quercitrin and rutin) were isolated and identified by high performance liquid chromatography, gas chromatography and thin layer chromatography. However, avicularin, which was known as one of the main constituents of flavonoid, was not detected.

초음파분무를 이용한 MOCVD법으로 강유전 BaTiO3 박막을 제조하였다. 초음파 분무 MOCVD법은 비교적 저온에서도 후열처리없이 결정화된 박막의 제조가 가능하다. 증착한 박막은 기판온도가 증가할수록 (110) 우선 배향성을 가졌으며, 기판온도에 따라서 서로 다른 결정상을 나타내었다. 기판온도가 55$0^{\circ}C$인 경우에 증착한 박막은 결정화가 완전히 진행되지 않았으며, 결정립의 크기도 매우 작아 상온에서 입방정상의 특성을 보였다. $600^{\circ}C$에서 증착한 박막은 결정화가 진행되어 입자의 크기는 성장하였으나 의사 입방정상을유지하고 있었다. 반만 $650^{\circ}C$에서 증착한 박막은 결정화뿐만 아니라 주상으로 성장하여 수직 방향으로는 박막 두께의 크기를 가져 CV 특성에서 이력곡선을 보였으며, 정전용량의 온도 변화에 따른 특성에서도 상전이의 특성을 나타내었다.

본 연구에서는 경보에 관한 지식을 획득하는 방법으로 경보간의 논리적 물리적 상관관계를 평가하여 지식구조를 설정하는 방법을 사용하고 있다. 이 지식구조를 지식기반으로 추론하여 주어진 상황에서 필요 없는 경보를 제거하거나 억제하며, 표시된 경보에 대해서도 운전원 조치의 긴급성을 운전상황에 따라 평가하여 우선순위를 동적으로 표시하는 지식기반 다이나믹 경보처리기술을 개발한다. 이를 위해 경보 운전절차서에 나타난 개별 경보들 중에서 주요계통경보들을 운전모드별로 분류하고, 연동신호에 의한 경보와 물리적인 원인-결과의 연동관계의 경보로 평가, 분석하여, 설정된 경보처리기술의 적용가능성을 평가하기 위해 가상 시나리오를 개발하고, 예비 prototype을 구현하였다.

The conductive transparent film is prepared by spraying thin salt solution. In stannic chloride solution as a base solution, various dopants such as Al, Co, Cu and Ni were dissolved respectively as a chloride state and then the films were made by spraying solutions on hot glass plates. The properties of them were compared with those of the stannic salt single component film. The films doped with copper oxide and nickle oxide were improved by decreasing their sheet resistivity and temperature coefficient of resistivity. In comparison with the sheet resistivity and temperature coefficient of resistivity of stannic oxide single component film, being 2.5 K ohm/$\textrm{cm}^2$ and -1650ppm/$^{\circ}C$ respectively, its values of the film containing 15 mol % of copper oxide and formed at 40$0^{\circ}C$ were 2.5K ohm/$\textrm{cm}^2$ and -920ppm/$^{\circ}C$ respectively. The film containing 15 mol % of nickel oxide and formed at 50$0^{\circ}C$ has shown its sheet resistivity and temperature coefficient 0.7 K ohm/$\textrm{cm}^2$ and -940ppm/$^{\circ}C$ respectively.

Most Annonaceous acetogenins are potently bioactive and offer exciting potential as new antitumor, pesticidal and other bioactivites. The major mode of action of the acetogenin is inhibition of electron transport in the mitochodria. Two known cytotoxic ketolactone Annonaceous acetogenins, (2,4-cis)-isoannonacin (compound 1) and (2,4-trans)-isoannonacin (compound 2), have been isolated from Asimina triloba (Annonaceae) by bioactivity directed fractionation. The structures were characterized on the basis of chemical and spectral data. Compounds 1 and 2, which are known but are first isolated from the seeds of this species, were ob-tained. In brine shrimp lethality test (BST), 1 and 2 exhibited cytotoxicity.

For the development of solid oxide fuel cell the joined interface formation between perovskite oxygen electrode and YSZ solid electrolyte is emphasized in the aspect of reducing the undisirable overpotential. The diffusion couple of LaMnO3 and YSZ was prepared by hot pressing at 130$0^{\circ}C$ in the flow of oxygen gas. The high temperature solid state reaction mechanism between LaMnO3 and YSZ is discussed on the basis of the cation composition profile through EDX analysis. The cation components in perovskite compound diffuse considerably into YSZ, while cations of YSZ diffuse little into perovskite.

중금속에 대한 식물의 내성여부와 중금속 스트레스하에서 식물의 생리적 특성을 파악하기 위해 좀개구리밥, 생이가래, 은행이끼, 수련, 부들 등 5종의 식물을 대상으로 카드뮴(Cd$^{2+}$)의 농도를 달리하여 처리한 후 시간별로 식물의 광합성효율을 분석하였다. 그 결과 좀개구리밥는 카드뮴에 가장 민감하게, 생이가래와 은행이끼 등은 조금 민감하게 반응하였으며, 수련 등은 다른 식물종에 비해 덜 민감한 것으로 나타나고 있다. 좀개구리밥은 카드뮴 농도가 증가할수록 정상적인 O-J-I-P 곡선에서 J, I, P의 값이 큰 폭으로 떨어지고 있으며, 이는 카드뮴 농도가 증가할수록 명반응 중심이 손상을 입거나 어떤 원인에 의해서 불활성됨으로써 광합성 효율 즉 Fv/Fm의 감소를 일으키기 때문이다.
