This study investigated the phenomena of membrane fouling by NOM and the effect of the fouling on removal of micro-pollutants. NOM has a great effect on decline of permeate flux. Permeate flow rate was reduced by 88% in RO and 34.8% in NF for 323hr operation period. Removal rate of UV_(254), is 87.4% in RO and 78.5% in NF and removal rate of DOC is 42.7% in RO and 32.9% in NF for 2㎎/l humic acid. Removal efficiency of the micmpollutants by the RO and NF membranes fouled by humic acid was mostly lower than that by the new membrane. The concentration polarization which affects the flux and the rejection was thought to occur in the active layer of the membrane, as the membrane was getting fouled.

In Ron Tong Pyun(論痛編), pathological mechanisms are explained on the basis of the so-called 'Eum-Yang(陰陽)" theory. Summerizing the contents of the Ron Tong Fyun(論痛編) in reference to the contents of successive generation note. the contents were as follows: Through the hard and soft of muscle, strenth and weakness of skeleton, densty and sparseness of complexion, thick and thin of the intestines and the stomach, we find out the difference of the pain by the acupuncture and moxibustion, tolerance of the drug. The people of the thick muscle, smooth skin, strenthen skeleton have a tolerence of the acupuncture and moxibustion. The people of the thick stomach, black skin, stenthen skeleton have the tolerence of drug.

The purpose of this study was to survey food service management practices and in order to provide basic information and efficiency model. The analysis materials are self-completed questionnaires of 71 child care centers in Bucheon, Kyunggi Province. The followings are about the results of this study. There is a quite great gap in the total number of the children between public child-care centers and private child-care centers. On the average cost of lunch and interim snack between public child-care centers and private one there were not much differences however, the home day-care centers had higher cost than the former. The meal mostly was prepared by a cook, but most home day-care centers was prepared by directors. The first difficulties of meal management were not enough space to cook in public child-care centers and big private one, small private and home day-care centers were about budget. The menus were monthly planned by the directors in public child-care centers, while they was weekly planned in private child-care centers and home day-care centers. All of child-care centers in Bucheon have no dietitian. The three types of child-care centers all considered the balanced nutrition and food preference of the children the most. They mostly referred to the menus offered by Bucheon Educare Information Center. In conclusion, the role of Educare Information Center in food service management is very crucial.

School informative project of a part of the educational information intensive society is by using the information technical application works, so to uplift on information intensive society and contribute to diffusion of opening education, and than to promote the information intensive society. Online world in all classrooms connect the computer network, this is the ultimate object for to push the school informative project. In this paper. We analyze the actual conditions of school informative project to be thought the main fact to perform the educational information and then to arrange the notion of theory about the school informative project, as to develop an improving program, and normalization, efficiency, and activity of the educational information project, at last give the aim to develop the balanced educational information.

This study was reseached to investigate the effect of Hyulbuchukeotant(?????) and its component groups on diabetes, free radical and antioxidative defense system in alloxan-induced diabetic rats, The experimental group was divided into three groups: Hyulbuchukeotang (HCT), and its components groups, Sayeoksan(H-sa) and Dohong- samultant(H-do). The results were obtained as follows: In the study of effect on diabetes, the level of glucose was considerablely reduced by HCT, H-sa and H-do with high significancy. In the change of fat metabolism, all experimental groups significantly changed the level of triglyceride, total cholesterol and HDL cholesterol expecially HCT and H-do group, but H-sa group has less significancy. In the change of protein metabolism, all experimental groups changed the level of total protein and albumin with high significancy. In the change of kidney function, HCT decreased the level of creatinine and BUN with high significancy, H-sa and H-do did with some significancy too. In the study on free radical scavenging effect in vitro, it has shown that all experimental groups have significant suppressing effect on peroxidation of linoleic acid on concentration, and in the scavenging effect of DPPH radical, inhibitory effect of superoxide in xanthine-xanthine oxidase system and inhibitory effect on lipid peroxidation reaction by hydroxy radical in H₂O₂-Fe^2+ system, all experimental groups have some activity. In the study on antioxidative defense system in vivo, HCT reduced the amount of lipid peroxide in serum and liver with high significantcy, and H-sa, H-do group did too with some significancy. In hepatic catalase activity, all experimental groups had showed activity on catalase, but H-sa no significancy. In the level of hepatic hlutathione, HCT increased the amount of glutathione significantly, but other groups with no significancy. In the activity of glutathione-s-transferase, all experimental groups has decreasing effect with significancy. These results suggest that Hyulbuchukeotant(?????) has strong effect on diabetes and peroxidative damage by free radical, so it is useful to prevent diabetes.

The structure of sodium trans-bis(methyliminodiacetato) chromate(Ⅲ), C_10H_14O_8N_2CrNa, has been elucidated with two space groups P 1-; a=8.9856(6), b=13.308(1), c=6.261(1)Å, α=76.38(1), β=110.361(9), r=107.394(6)˚, V=662(2)Å^3, Z=2, μ=0.47mn^(-1), d=1.831Mg/㎥, R=0.0295 for 1901 independent reflections with F^2>2σ(F^2), and A2/n; a=13.65(5), b=6.261(1), c=16.85(6)Å, β=113.05(1)˚, V=1324(7)Å^3, Z=4, R=0.0287 for 1013 independent reflections with F^2>2σ(F^2). There are two different asymmetric half molecules in triclinic system and one asymmetric half molecule in monoclinic system. The structures of three different molecules are very similar in conformations. The four carboxyl O atoms and the two imino N atoms in each molecule produce a distorted octahedral coordination geometry around the Cr atom. The average distances of Cr-O(carboxyl) and Cr-N(imino) are 1.956 and 2.061Å respectively. Molecules are held together by ionic forces. In this paper, it has been also shown that the cell constants, Miller indices, atomic coordinates, lattice directions and reciprocal lattices of the two space groups can be mutually transformed.

This study was performed to research the antioxidant activities of Guibitang and its component groups. The experimental group was divided into six group: Guibitang (GB), Gamiguibitang (GA), Hyul-yak group (GB1), Gi-yak group (GB2), Ansinhaenggi-yak group (GB3) and Gami-yak group (GA1). The results were obtained as follows: In vitro All experimental groups had antioxidant activity in linoleic acid system on concentration in comparison with control group. And in DPPH radical scavenging experiment, all experimental groups had scavenging activity on concentration, especially GA1 group was higher than any others. The inhibitory effect experimental groups had inhibitory effects of superoxide generation on concentration, and the effect of Guibitang was better than Gamiguibitang. In component groups GA1 was highest and GB1 was lowest respectively. The inhibitory effect experiment on lipid peroxidation reaction in H₂O₂-Fe^2+ system showed that each experimental groups had inhibitory effects on lipid peroxidation reaction compared with control group. And GA1 group exhibit the best inhibition effect on lipid peroxidation reaction. In vivo the amounts of lipid peroxide rat on the level of serum was reduced in comparison with control group, especially gamiguibitang. The amounts of LPO on the level of liver was also reduced compared with control group. espeially gamiguibitang, guibitang, GB1 group. In hepatic catalase activity test, all experimental groups increased catalase activity, and that of guibitang, gamiguibitang, GB1 group were evident. The amounts of hepatic glutathione of experimental group increased in comparison with control group. And that of gamiguibitang, guibitang was more significant than component group.
