  • Effects of dietary fat and tomato on immune functions were investigated using BALB/c mice. Sixty male BALB/c mice weighing 16-17g were divided into two dietary groups. Control group was fed experimental chow (AIN-76 purified diet) supplemented with saturated fat (beef tallow) and unsaturated fat (safflower oil) at 5% level (weight basis), while treatment group was fed chow added with 0.5% (dry matter basis) of tomato (moisture content 95%) for 10 weeks. Organ weights, delayed-type hypersensitivity test, plaque-forming cell test, agglutination test, differential white cell count, and histological examination were performed at 4th, 7th, and 10th week after dietary treatment. Weight of spleen and spleen index of tomato group increased with increasing experimental period. Thymus index of tomato group was significantly higher than that of control group at 7 and 10 weeks (p<0.05). In delayed hypersensitivity test at 4th, 7th, and 10th week after dietary treatment, tomato group showed more significant increase in footpad swelling reaction 24 hr after challenge than control group (p<0.05). In plaque-forming cell test, tomato group fed 7 weeks increased more significantly than control group, while no significant difference was found between two groups at 10 weeks. Agglutination test decreased with increasing experimental period; tomato group at 10 weeks was higher than control group in antibody response to SRBC. In tomato group, Iympocyte percentage was slightly higher than that of control group, and spleen tissue showed active immune reaction caused by severe proliferation of white pulp.

  • The Korean traditional color passed down over countless generations has surpassed both surpassed both time and space and continue today to breathe life into its people's everyday. In order to clarify the characteristics of Korean traditional color blue and red, we investigate the names of them and measured the color tones of textile remains in Chosun era. The characteristics of Korean traditional color blue and red have been surveyed by means of the examination of color names in many famous literatures in Chosun era. Korean terms for color tones were characterized by enormous variety of epithes crowned on them. The color names mentioned contain many unaccountable epithes which were characterized also deep colors and light colors were dominant in it. As a means of enhancing possibilities within limited colors, the commoners increased the names for varying tones of blue color group(32kinds) and red color group(40kinds). These "blue(indigo dyeing)' and 'red(safflower dyeing)' in Chosun era were shown very high frequency in use and the costume colors in Royal Court. With combination of these various blue and red colors they represented a thought of color based on Yinyang Theory and created a polished aesthetic taste. The color samples of textile remains in museum were measured and designated by Munsell color system and the ISCC-NBS color designation system. THe appeared rates were derived on Chosun era and features of colors using on the period were discussed. We aim to present specific recipes in indigo dyeing and safflower dyeing for using our apparel product and folk art.

  • Concentrations of benzo[$\alpha$]pyrene in edible oils from Korean market were evaluated by high performance liquid chromatography. Benzo[$\alpha$]pyrene known of the carcinogenic polycyclic aromatic hydrocarbons(PAHs), has been found at variable concentrations in several foods. This is associated with several factors during the process including contaminated raw materials, exposure of environment, and procedure of process or cooking. The levels of benzo[$\alpha$]pyrene were ranged from 0.5 to 1.4 $\mu$g/kg in virgin olive oil. Benzo[$\alpha$]pyrene contents in refined and virgin olive oil, sesame oil, soybean oil, corn oil, sunflower oil, safflower oil, and processed oil were 0.6-1.0 $\mu$g/kg, 0.9-1.3 $\mu$g/kg, 0.6-3.3 $\mu$g/kg, 0.5-1.1 $\mu$g/kg, 1.2-1.7 $\mu$g/kg, 1.0-2.1 $\mu$g/kg, and 1.0-1.4 $\mu$g/kg, respectively.

  • This study aims to compare the properties of natural dye stuffs, such as color, dyeability, fastness, and marketability, to analyze the differences noted by expert groups regarding the properties of the stuffs, and to make a positioning of the stuffs. A survey of experts in academia, business, and the art of natural dyeing was conducted, with an evaluation of 23 types of the stuff's properties. There is a correlation between the properties of the stuffs, and evaluating dye stuffs differs according to the group to which it belongs. X-axis relates to color and Y-axis refers to fastness in the positioning of the stuff. There are different relationships between properties according to their group. Color is significantly associated with marketability in art experts however, fastness is closely connected with marketability in business. The stuffs can be divided into five clusters. Cluster I includes indigo and persimmon, and is marked by excellent color, dyeability, fastness, and marketability, Cluster II contains safflower and sappan wood, which are excellent colors, yet suffer from low marketability on account of their medium to low fastness. Cluster III includes red, purple, and brown dyes, and onion and rhubarb, and has medium properties. Cluster IV is mugwort and yellow dyes, except onion and rhubarb, and features low properties. Cluster V is loess, featuring medium color and low fastness.

  • Since 1993, a total of 50 problematic plant diseases unrecorded in Korea were surveyed in Gyeongnam province. Totally 34 new host plants to corresponding pathogens investigated in this study were 5 fruit trees, 9 vegetables, 12 ornamental plants, 3 industrial crops, and 5 medicinal plants. Among the newly recorded fruit tree diseases, fruit rot of pomegranate caused by Coniella granati and Rhizopus soft rot of peach caused by Rhizopus nigricans damaged severely showing 65.5% and 82.4% infection rate. Among the vegetable diseases, corynespora leaf spot of pepper caused by Corynespora cassiicola and the crown gall of pepper caused by Agrobacterium tumefaciens, powdery mildew of tomato caused by Oidiopsis taurica were the most severe revealing 47.6%, 84.7%, and 54.5% infection rate in heavily infected fields, respectively. In ornamental plants, collar rot of lily caused by Sclerotium rolfsii, gray mold of primula caused by Botrytis cinerea, soot leaf blight of dendrobium caused by Pseudocercospora dendrobium, sclerotinia rot of obedient plant caused by Sclerotinia sclerotiorum showed 32.7 to 64.8% disease incidence. On three industrial plants such as sword bean, broad bean, and cowpea, eight diseases were firstly found in this study. Among the diseases occurring on broad bean, rust caused by Uromyces viciae-fabae and red spot caused by Botrytis fabae were the major limiting factor for the cultivation of the plant showing over 64% infection rate in fields. In medicinal plants, anthracnose of safflower caused by Collectotrichum acutatum was considered the most severe disease on the plant and followed by collar rot caused by Sclerotium rolfsii.(중략)

  • The present study explored the short-term effects of dietary conjugated-linoleic acid (CLA) on liver lipid metabolism in starved/refed Otsuka Long Evans Tokushima Fatty (OLETF) rats. Male OLETF rats (12 weeks old) were starved for 24 hours, then refed for 48 hours with either a CLA diet [7.5% CLA and 7.5% Safflower oil (SAF)] or a SAF control diet (15% SAF). The results demonstrated a 30% reduction of hepatic triglyceride (TG) concentration in the CLA group when compared to the control group. Liver cholesterol concentration was also 26% lower in the CLA fed rats. The activity of mitochondrial carnitine palmitoyltransferase, the rate-limiting enzyme of fatty acid oxidation, was moderately elevated by 1.2-fold in the livers of the CLA group when compared to the control. In contrast, phosphatidate phosphohydrolase, the rate-limiting enzyme for TG synthesis, was found to be 20% lower in the livers of the CLA-fed rats. Therefore, dietary CLA evidently lowers liver lipid concentrations through a reduced TG synthesis and enhanced fatty acid oxidation in starved/refed OLETF rats.

  • This study is about reproduction of Yoseon-Cheobli excavated from Byun-su tomb in earlier Joseon Dynasty. There are three Yoseon-Cheobli in Byun-su tomb. The producing process is made in concrete by suggesting the process of producing clothing. Based on the Annals of the Joseon Dynasty, the most frequently recorded one, was reproduced by dying fabric with safflower and indigo plants. Through the research about their specific size, sewing method and construction, it have been produced in the following. First, the revealing that collar to be half-square and to compose the line in the center of collar. The width of the collar is 11.6 12.1cm. Second, the 21~22 pairs of waist lines that are 13~14cm in width fixed at intervals of 0.3cm. The method of making waist lines is twisting either fabrics or silk threads. Third, fine gathering around the part of the waist of skirt, and the size of fold surface is 0.2cm. Sewing method needs running stitch and backstitch. As the result of producing the cloth, it became to possess more ornamental features after transformation suitable to the new environment while the same remained functional features for everyday life such as a dressing shape, length of the bodice and curvy completion line of a collar strip.
