Medicinal Precipitated Clacium Carbonate is prepared by the interaction of Calcium Chloride and Ammonium Carbonate Solutions in this study. It has been known that the particle size of Precipitated Calcium Carbonate is greatly affected by the concentration, temperature, and moli-ratio of reactant solutions as well as the temperature at which the precipitate is dried and the temperature of washing water. The purpose of this study is to determine the optimum preparation Condition of medicinal Precipitated Calcium Carbonate. A randomized complete block design wuggested by G.E.P. Box and K.B.Wilson was for this purpose. The optimum preparation condition of light and fine precipitated Calcium Carbonate obtained from this study is as follows : 1) The reacting temperature range is 25∼45℃ 2) The concentration range of reactant solutions is 10∼30% 3) The optimum mole-ratio (CaCl/(NH) CO) is 1.0∼2.0. 4) The drying temperature range is 60∼80℃. 5) Temperature range of washing water is 25∼60℃.

The objective of this study was to understand the conservation of gene resources and provide information for mass selection of winter bud characters among the selected populations of Kalopanax septemlobus Koidz using analysis of variance(ANOVA) tests. The obtained results are shown below; 1. Ten populations of K. septemlobus were selected for the study of the variation of winter bud characters in Korea. The results of the analysis of variance(ANOVA) tests shows that there were statistically significant differences in all of the winter bud characters among those populations. 2. Correlation analysis shows that width between Height and DBH(Diameter at breast height) characters have negative relationship with all of the characters, as ABL(Apical branch length), ABW(Apical branch width), AWBL(Apical branch winter bud length), AWBW(Apical branch winter bud width), ABT(Apical branch No. of thorns), ABLB(Apical branch No. of lateral bud) and LBL(Lateral branch length), LBW(Lateral branch width), LBT(Lateral branch No. of thorns), LBLB(Lateral branch No. of lateral bud). 3. The result of principal component analysis(PCA) for winter buds showed that the first principal components(PC s) to the fourth principal component explains about 78% of the total variation. The first principal component(PC) was correlated with AWBW, LWBW, and LBL and the ratio of ABL/ABW and LBL/LBW out of 16 winter bud characters. The second principal component correlated with ABL, ABW, ABLB, LWBL(Lateral branch winter bud length), and LBW and the ratio of AWBL/AWBW. The third principal component correlated with ABL, ABW, LWBL, LBL, and the ratio of LBL/LBW. The fourth principal component correlated with LBL and the ratio of LWBL/LWBW(Lateral branch winter bud width), LBL/LBW. Therefore, these characters were important to analysis of the variation for winter bud characters among selected populations of K. septemlobus in Korea. 4. Cluster analysis using the average linkage method based on 10 selected populations for the 16 winter bud characters of K. septemlobus in Korea showed a clustering into two groups by level of distance 1.1(Fig. 3). As can be seen in Fig. 3, Group I consisted of three areas(Mt. Sori, Mt. Balwang and Mt. Worak) and Group Ⅱ contisted of seven areas(Suwon, Mt. Chuwang, Mt. Kyeryong, Mt. Kaji, Mt. Jiri, Muan, and Mt. Halla). The result of cluster analysis for winter bud characters corresponded well with principal component analysis, as is shown in Fig. 2.

This study was performed to develop a rapid test kit for pathogenic Staphylococcus in various samples. The rapid detection kit has been fabricated based on nitrocellulose lateral-flow strip. Colloidal gold and Staphylococcus antibodies were used as a tag and a receptor, respectively. Manually spotted Staphylococcus antibody and anti-mouse antibody on the surface of nitrocellulose membrane were used as test and control lines, espectively. Feasibility of the rapid kit to detect Staphylococcus aureus in samples were evaluated. The intensity of the color of the tes line started to increase with the samples in which higher concentration of the cells were contained. The sensitivity of the sensor was 106 cfu/mL Staphylococcus spiked in PBS. Also, the rapid test kit could detect 105 cfu/mL of Staphylococcus in chicken meat extract.

As a new protective group for diols, cyclic oxalates (20) (24) were synthesized by using oxalyl chloride, ethyl oxalyl chloride, diethyl oxalate and oxalic acid. In the reaction of diol with oxalyl chloride, the product was a mixture of the cyclic oxalate (20) and mono oxalated(21). When ethyl oxalyl chloride was used which pyridine as base, acyclic oxalates (22) (25) were obtained. Whereas ethyl oxalyl chloride which triethylamine instead of pyridine, cyclic oxalates (20) (24) as well as acyclic oxalates (22) (25) were obtained. Using diethyl oxalate, the amounts of cyclic oxalates (20) (24) were increased, but there were some difficulties in separations of its desired products. Oxalic acid, however, did not afford cyclic oxalates but gave formate which probably was formed by decarboxylation of hydroxyoxalyl group.

Formation of edible films from food-process by-products, defatted soy bean meal (DSM), soybean meal-extracted soy protein, and persimmon peel and whey protein, has been investigated. The DSM-based film had a higher tensile strength (TS) (4-12 MPa) and percentage elongation at break (%E) (2.5-16.0%) than the films made of soybean meal-extracted soy protein or persimmon peel and whey protein, and the DSM-based film was selected as the base film material for developing an antimicrobial edible film incorporating malic acid. The malic acid-incorporating DSM-based film (MA-DSM film) inhibited Salmonella Typhimurium (2.2, 3.2, and 4.2 log CFU/cm2). The inhibition increased with the increase of the concentration of malic acid in the film from 10 to 30% (w/w, dry basis). The addition of malic acid increased lightness and %E (stretchability) and decreased TS (strongness) and Young’s modulus (stiffness) of the MA-DSM film. However, the water vapor permeability did not change after the addition of malic acid, indicating the moisture barrier property of the DSM-based film was not affected by the incorporation of malic acid in the film matrix. The results demonstrated the potential of applying MA-DSM films to food products and control surface contamination of the products with respect to Salmonella.

Sorbus alnifolia (Siebold & Zucc.) K. Koch were usually distributed in the middle or the top of the mountain under 1,100 m of sea level as a small population. Based on physiognomy, the predominant species in the natural populations of S. alnifolia can be summarized as follows; Quercus aliena-S. alnifolia in Mt. Mani; Q. varirabilis-S. alnifolia in Mt. Bawang and Mt. Geumo; S. alnifolia in Mt. Gaji, Mt. Duryun and Wando. On the other hand, in the case of Anmyundo population, there were no predominant species and S. alnifolia were growing with Q. serrata, Q. varirabilis, Pinus densiflora and P. thunbergii. The four species (Q. serrata, Prunus sargentii, Lindera obtusiloba and Smilax chian) appeared in all the natural populations of S. alnifolia. The sums of important values of S. alnifolia for each layer were 230.3% in tree layer, 124.3% in subtree layer, and 9.1% in shrub layer, respectively. The Morista’s indexs of S. alnifolia were 1.12 in tree layer, 1.00 in subtree layer, and 0.28 in shrub layer, respectively. This result shows that S. alnifolia occurs randomly in tree and subtree layer but regularly in shrub layer. A total of 91 species was found in all the surveyed plots. Species diversity of S. alnifolia populations ranged from 0.78 to 1.30. Evenness and dominance showed the ranges of 0.75~0.89 and 0.11~0.25, respectively. Cluster analysis based on the species composition showed that Wando, Mt. Duryun, Mt. Gaji, and Mt. Mani composed one group and Anmyundo, Mt. Geumo and Mt. Balwang made up the other group.

Sobus alnifolia (Siebold & Zucc.) K. Koch. which can be used as honey plant is a deciduous broadleaved tree belonging to Rosaceae family. We examined flower morphological characteristics and classification among 9 selected populations of S. alnifolia in order to provide basic data for selection breeding. The main results examined flower characteristics from 9 populations are summarized as follows; While Mt. Chukryung population was larger in flower size compared with other populations, Mt. Deogyu population was smaller among populations. Its principal components analysis (PCA) results showed that it show 64.4% accumulated explanation from three PC. The characteristics such as flower width, petal length and petal width were highly contributed for classification among populations. According to cluster analysis based on the flower morphological characteristics, the natural S. alnifolia populations were classified into three groups; the first group of Mt. Gwangyo, Anmyundo, Mt. Chukyung, the second group of Mt. Geumo, Mt. Duryun, Mt. Deogyu, the third group of Mt. Mani, Mt. Gaji, Mt. Worak.
