Since the urban environmental colors as a starting point of the research on environmental colors of the building depend on the environmental characteristics of the complex and various physical and social culture to improve the visual order of the urban landscape and don't establish its system and order, the importance of the visual effects of urban environment has been suggested through the experimental and theoretical research. It is to want to abstract the factor of surface pattern from the side of two dimentional physical factor and perceptual of architecture surface construction by concreting calssifing the criterion of analysis in to rank phase, perceptual concept, finding out basic composition factor of shape and opening architecture surface construction of design. To suggest the material of mere practical color design, this study examines the research of exterial colors of the building on the street, prescribes the characteristics of the building with other environmental factors which compose the colors and aims at suggesting the actual color design materials making the trend of colors the object of the research.

To elucidate the characteristics of leaf senescence in relation to the development of rice grain, course of change in the content of chlorophylls, soluble protein, and total phenolics, course of increase in dry weight of rice caryopsis, and their interrelationships were studied, using Jinheung, a typical Japonica variety, T(N)-1, an Indica, IR 1317-266-34 and Suwon No. 256, Indica×Japonica progenies. The results obtained are summarized as follows: 1. The variety T(N)-1 and IR 1317-266-34 showed a sigmoidal time course of the rice caryopsis development in dry weight in contrast to the continuous increase in the dry weight of rice caryopsis to 40 days after heading in the variety Jinheung and Suwon No. 256. 2. The chlorophyll content of leaf blades decreased during the course of grain development; the degree of decrease in the chlorophyll content being the highest in the IR 1317-266-34 and being the lowest in the Suwon No. 256. 3. Total pheonolics content of the leaf blades increased during the course of grain development, showing varietal difference in the accumulation pattern: major accumulation occurred during 30 to 35 days after heading in the Jinheung and IR 1317-266-34 in contrast to a rather linear increase after heading in the Suwon No. 256 and T(N)-1. 4. The content of soluble protein of the leaf blades decreased during the course of grain development in all varieties tested except for the Suwon No. 256, which showed some increase in the flag leaf during the first 15 days after heading and little decrease in other leaves during the later period. 5. Significant positive correlationship existed between the chlorophyll content and the soluble protein content of leaf blades during their senescence, r value being ??, ??, ??, ??, respectively for the Jinheuing, T(N)-1, Suwon No. 256, and IR 1317-266-34.

In order to understand natural language, we have to follow the process "Input → Lexical Analysis → Syntactic Analysis → Semantic Analysis". Among those, "syntactic analysis" plays the most important role since it is able to be applied to various fields such as natural language query systems, natural language interface systems, text summary systems, and machine translation systems. It is also important to analyze a sentence containing ambiguity. In this paper, we propose an algorithm to parse the Korean language using chart. It is implemented using Prolog programming language.

The Hough transform is a robust technique which is useful in detecting strait lines in an edge-enhanced picture. However, the conventional Hough transform to recover ellipses has been limited by slow speed and excessive memory size. This paper presents algorithm techniques aimed at improving the efficiency and reducing the memory size of the accumulator array. In this paper, five geometries of symmetric points of an ellipse are used to improve the efficiency of using a conventional HT for the detection of an ellipse. This technique greatly reduces the memory space of the accumulator needed for the detection of ellipses using the HT.

金柱憲,權容雄 서울大學校 農科大學 1977 서울대농학연구지 Vol.2 No.2

The chloroplast pigment composition, its change and anthocyanins development during grain ripening were studied in relation to the reddish discoloration and earlier leaf senescence prominent in the Indica × Japonica cross varieties, using Jinheung, a Japonica, T(N)-1, an Indica, IR1317 and Suwon No. 256, Indica × Japonica progenies. 1. Chloroplast pigments of rice leaf blade were composed of β-carotene (Rf 0.898), pheophytin a (Rf 0.616), lutein (Rf 0.477), chlorophyll a′(Rf 0.398), chlorophyll a (Rf 0.323), chlorophyll b′(Rf 0.247), chlorophyll b (Rf 0.198), violaxanthin (Rf 0.101), neoxanthin (Rf 0.037) as separated on thin layer of silica gel with 5% binder, employing solvent system developed in this experiment of petroleum ether: acetone=4:1(v/v) and identified on the basis of their absorption spectra after elution. 2. All of the pigments were present in all varieties tested throughout the course of leaf senscence after heading. But, there was distinct varietal difference in the relative content of the pigments: the greatest variation among varieties existed in the content of neoxanthin (C.V.=57%) and the least in the content of chlorophyll b (C.V.=5%). 3. The total content of carotenoid pigments relative to that of chlorophyll a decreased in the variety T(N)-1 and Suwon No. 256 during 20 days after heading, while it increased in the variety Jinheung and IR1317-266-34 during the same period. The increase shown in the variety Jinheung was mainly due to increase in the relative content of β-carotene and lutein, and in the variety IR1317-266-34 it was due to β-carotene, violaxanthin and neoxanthin. 4. Fast decrease in the chlorophyll content occurred during the first 10 days after heading in the variety T(N)-1 and IR1317-266-34 in contrast to later and gradual decrease in the variety Jinheung and Suwon No. 256. 5. Total anthocyanins content of the leaf blade began to increase at about 5 days after heading in the variety Suwon No. 256 and at about 20 days in the variety Jinheung, IR1317-266-34 and T(N)-1. The fastest accumulation occurred at 20-25 days after heading in the variety Jinheung and IR1317-266-34, 25-30 days in the variety T(N)-1, 30-35 days in the variety Suwon No. 256. With respect to variety the order of magnitude in the maximum content shown after heading was T(N)-1<Suwon No. 256<Jinheung<IR1317-266-34. 6. Highly significant negative correlationship was found between the contents of chlorophyll and total anthocyanins during the course of leaf senescence in the variety Jinheung (??), IR1317-266-34 (??) and T(N)-1 (??), but such a correlation was not observed in the variety Suwon No. 256 (??).

국산 점토를 이용한 폐수 중의 중금속 흡착에 관한 연구

온웅구,김낙주,최고열 서울産業大學校 2001 논문집 Vol.52 No.1

국내에서 무작위로 채취한 점토와 폐도자기를 이용하여 폐수중의 중금속의 흡착 실험을 수행하였다. 중금속 처리제로서 점토의 사용 가능성을 알아보기 위하여, pH, 온도, 흡착 시간 및 공존 이온 등이 점토의 흡착 특성과 흡착 능력에 미치는 영향에 대하여 연구하였다. 모든 시료에 대하여 흡착 시간은 30분내에서 흡착 평형을 이루었다. 온도는 흡착 효율에 큰 영향은 없지만 낮은 온도에서 흡착량이 약간 증가하였으며, 최적 pH는 6 이상이었다. Cu(II)나 Zn(II)과 같은 양이온이 공존하고 있을 때는 서로 경쟁적으로 흡착하려는 성질 때문에 Pb(II) 흡착능은 저하하였다. 폐도자기는 불산 수용액으로 처리하므로서 흡착능이 증가하였다. The adsorption of heavy metals in the waste water was carried out on the various domestic clays and waste pottery. The effect of parameters such as pH, temperature, adsorption time, and coexisting cations on the sorption ability and characteristics was investigated to find out whether the clays could be used as adsorbents. Adsorption equilibrium was reached within 30 minutes on all the clays. Adsorption efficiency was not influenced by temperature, but slightly increased at lower temperature. The optimum pH was found to be above 6. When other cation such as Cu(II) or Zn(II) coexisted with Pb(II), the adsorption amount of Pb(II) decreased because of the competing adsorption. The sorption ability of waste pottery was enhanced by treating HF solution.
