Let D be an integral domain, $\bar{D}$ be the integral closure of D, * be a star operation of finite character on D, $*_w$ be the so-called $*_w$-operation on D induced by *, X be an indeterminate over D, $N_*=\{f{\in}D[X]{\mid}c(f)^*=D\}$, and $Kr(D,*)=\{0\}{\cup}\{\frac{f}{g}{\mid}0{\neq}f,\;g{\in}D[X]$ and there is an $0{\neq}h{\in}D[X]$ such that $(c(f)c(h))^*{\subseteq}(c(g)c(h))^*$}. In this paper, we show that D is a *-quasi-Pr$\ddot{u}$fer domain if and only if $\bar{D}[X]_{N_*}=Kr(D,*_w)$. As a corollary, we recover Fontana-Jara-Santos's result that D is a Pr$\ddot{u}$fer *-multiplication domain if and only if $D[X]_{N_*} = Kr(D,*_w)$.

This Analyzed case study of measuring displacement, implemented laboratory investigation, and in-situ testing in order to interpret ground subsidence risk rating by excavation work. Since geological features of each country are different, it is necessary to objectify or classify quantitatively ground subsidence risk evaluation in accordance with Korean ground character. Induced main factor that could be evaluated and used to predicted ground subsidence risk through literature investigation and analysis study on research trend related to the ground subsidence. Major factors of ground subsidence might be classified by geological features as overburden, boundary surface of ground, soil, rock and water. These factors affect each other differently in accordance with type of ground that's classified soil, rock, or complex. Then rock could be classified including limestone element or not, also in case of the latter it might be classified whether brittle shear zone or not.

Exposing yeast cells with a certain genotype to different inducers, the ability of the yeast cells (Saccharomyces cerevisiae) to obtain enhanced fermentation for carbohydrates was observed. Regardless of the preexposure to any substrate, the inherent character incapable of fermenting a certain carbohydrate was maintained, while utilization of carbohydrates by the cells with a certain gene markers was varied by the previous conditions where they were exposed. Galactose was the best inducer for the cells to elaborate melibiase, even the galactose was not utilized as a substrate. Preexposure to galactose seemed to be necessary for the cells to utilize galactose and melibiose. Galactose fermentation by GA cells was enhanced by the exposure of the cells to galactose, but not to melibiose, raffinose, sucrose or glucose. Delayed fermentation of sucrose by the cells exposed to glucose or melibiose, but not to galactose, was observed. Raffinose fermentation was obtained by the cells with either SU RAF or GA ME genes, but the enhanced fermentation of raffinose seemed to be dependent on which inducer the cells were exposed previously and enzymes induced by the inducer to break either one of the linkages of raffinose molecule, the alpha0galactosidic or the beta-fructo-furanosidic.

Culture is way of life. And a culture is based on the view of nature and humun being. Korea has many kinds of tradition. Out of them, Korean character Hangul, food and medicine have been succeeded as they were in old days. So I tried to induce Korean view of nature and human being from those traditions. The common principle induced from them is Yin-yang and five elements. Yin-yang and five elements is away to cognize nature by Korean people. That means Yin-yang is thought to be the principle of nature. Nature is what life is born or produced. And mankind is a part of nature. Thus Yin-yang and five elements works on mankind in the same way as they do on nature. Mankind is born and grows on the earth. So human body consists of four, parts of the earth, which are light, air, water and soil. It is essential for human being to maintain balance and harmony in nature with nature and as nature.

The azobenzene dendrimer is one of the dendrimeric macromolecules that include the azo-group exhibiting a photochromic character. Due to the presence of the charge transfer element of the azo-group and its rod-shaped structure, these compounds are expected to have potential interest in electronics and photoelectronics, especially in nonlinear optics. In the present paper, we give pressure stimulation to organic thin films and detect the induced displacement current. Functional photoisometrization organic molecular the photo-stimulus to organic monomolecular L films and LB films of dendrimer and SASH were performed. The SASH organic monolayer in case of pressure stimulus occurred that positive course but in case of the photo-stimulus compared positive and negative. It is assumed that generation forms of displacement current were measured when photo-stimulus for impression.

The article is devoted to the study of some hi-and tricyclic derivatives of aziridine as materials lot newindicators of ionizing radiation. To create high sensitive materials some aspects of photo induced ring opening processes in aziridine derivatives in ethanol solutions and in polymeric matrix were studied and two steps character of the processes investigated was established. Two types of radioindicators were suggested and preliminary tested. The new way of synthesis of radiochromic derivatives of aziridine was developed and series of target compounds synthesized.

The ultraviolet photochemistry of N,N'-bis(salicylidene)ethylenediamine copper(II), Cu(sal)2en, was investigated with low pressure mercury lamp. Redution of Cu(Ⅱ) and formation of Cl- were shown on 254 nm irradiation both for aerated and deaerated chlorinated hydrocarbon solvent such as CH2Cl2, chloroform, and 1,2-dichloroethane. Relatively long lived $({\tau}=100{\mu}sec)$ intermediate was detected by flash photolysis. Overall photo-process can be described as the formation of Cl- and new copper complex, product(1) by chlorohydrocarbon mediation, photoinduced reduction by abstraction of halogen from solvent, followed by redox induced substitution of axial ligand with chlorine. Product(1) is possibly Cu(III) chlorosalicylaldeimido complex and cyclic -CH2CH2- moiety is absent in the structure. 247nm band of Cu(sal)2en should contain ligand to metal charge transfer character.

The surface enhanced Raman scatterings of Zn(Ⅱ) tetrakis (4-N-methyl pyridyl) porphyrins were studied in silver sol. Zn(Ⅱ) tetrakis (4-N-methyl pyridyl) porphyrin was found to be adsorbed on silver surface via flat-on geometry with some inhomogeneous distribution in the orientation of pyridyl groups. Both the selective enhancement of Raman modes depending on the mode character and the theoretical arguments of SERS are utilized to support the above conclusion. The surface induced substitution reaction of Mn(Ⅲ) tetrakis (4-N-methyl pyridyl) porphyrin chloride to Ag(Ⅱ) tetrakis (4-N-methyl pyridyl) porphyrin was detected via surface enhanced Raman spectrum.

홧병은 민간에서 많이 통용되는 한국의 문화관련질환으로 그간 정신과의사와 한의사 사이에서 많은 연구가 진행되어 왔다. 정신과의사는 홧병을 특유한 병리적인 경과를 밟는 '병'으로의 의미로 설명한데 반해 한의사는 화의 양상을 가진 '증'의 개념으로 이를 해석하고 있는 것을 볼 수 있다. 저자는 기존의 홧병연구를 바탕으로 한의학적으로 해석을 하여볼 때, 발병원인은 지속된 억울된 감정으로 인한 간기울결로 말미암고, 홧병의 발생이 여성에게 많은 까닭은 여성이 스트레스를 잘 풀지 못하며 생리적, 장기적 취약점이 있으며, 화의 위로 상승하는 성질과 병이 신수가 심화를 억제하지 못하는데서 비롯하므로 증상이 화의 역동성과 연관된다는 점, 그리고 발병이 만성화의 경과를 밟는 이유는 복합감정이 문제가 되고 또 감정이 오래되어 화로 바뀌며 나이가 들어 수가 화를 억제하지 못하는 시기에 발병한다는 점으로 홧병을 해석할 수 있었다. 이는 정신과의사의 임상적 경과의 관찰과 한의사의 화에 대한 연구가 상호의 협조가 병의 경과와 병리기전 예후 및 치료대책을 정립해 나가는데 있어서 더욱 필요함을 제시해 주고 있다.

본 시험은 1981~1982년에 걸쳐 공시품종을 "수원5호"와 "수원9호"로 단작과 맥후작으로 파종하고 도복처리시기를 개화시, 개화기, 개화종기에, 도복정도를 30$^{\circ}$, 60$^{\circ}$, 90$^{\circ}$로 유인 처리하여 시험한 결과는 다음과 같다. 1. 건경중은 작기간 차이보다 품종간 차이가 더욱 유의적이어서 수원5호는 개화시처리 반응이 둔한 반면 수원9호는 2파종기 모두 도복시기가 빠르고 도복정도가 심할수록 감소경향이 컸다. 2. 착삭부위장은 품종간보다 작기차이가 민감하여서 2품종 모두 단작보다는 맥후작에서 도복에 의한 감소정도가 명확하였다. 3. 주당삭수는 개화시의 처리에서 감소가 극심하였고 개화기 및 개화종기 처리에서는 차이가 없었으며 이들의 경향은 맥후작보다 단작에서 유의적으로 감소되었다. 4. 수원5호는 맥후작에서 도복에 의한 천립중의 감소가 별로 인정되지 않았다. 5. 도복에 의한 등숙률의 저락현상은 맥후작보다 단작에서 그리고 개화시의 도복처리에서 특히 치명적이었다. 6. 도복에 의한 참깨 종실수량의 감소경향은 수원5호의 경우 단작에서, 수원9호의 경우 맥후작에 극심한 경향이었다.의 경우 맥후작에 극심한 경향이었다.
