  • Semi-micro-HPLC using a column-switching technique was developed for simultaneous determination of vitamin A and E contents in infant formula. Vitamin A and E were extracted by PDA - HPLC with reversed phase column using organic solvent and their contents in Certified Reference Material (CRM) and infant formula were determined and compared with hydrolysis method and rapid extraction. Developed method has many advantages of simple and rapid sample preparation and simultaneous determination of vitamin A and E by micro-HPLC using reversed phase column.

  • This study attempts to analyze the characteristics of the space composition of the apartments and the general principles of apartments unit plans in Gyeongnam. Literature review and content analysis method were used in his research. The data of 108 unit plans were collected from e-catalogue and model houses of housing construction firms. The results of this study were as follows; 1) The general principle of Gyeongnam apartment unit plans, the tendency of 4LDk+2BATH type, 4bay, central type living room were showed. 2) In the point LDK and couple's bed room, LDK area become large and open type and couple's bed room were showed bed room+dress+powder+bath type as Maser's zone. 3) The entrance has a intermediate space as a balcony or a former space and the privacy of LDK space was protected from the entrance. 4) In the case of support space, generally support kitchen and laundry space were offered and several balconies were utilized. In fact, he differences of apartment plan composition between central cities and Gyeongnam were no showed. Therefore, these tendencies on plan composition of apartment in Gyeongnam were followed the general principles of Korean unit plans.

  • These experiments were carried out to examine efficacy of soil solarization for control of pink root disease by means of mulching with transparent polyethylene sheets in the hot season. The effects of soil solarization on incidence of pink-root disease caused by Pyrenochaeta terrestris and on onion growth and on populations of soil fungi were investigated. Solarization was dramatically effective in reducing pink root incidence in onion seedling and harvested onion bulb. A 30-day and 40-day solarization treatment significantly improved seedling survival and increased yield of 'Changnyeong-deago' onion while decreasing incidence of pink root. Populations of soil fungi from fields planted to onion were assayed on selective media. Solarization treatment was effective in reducing populations of P. terrestris, Pythium spp., and Rhizoctonia sp. in soil. Increase of yield of onion bulbs was associated with control of soil-borne pathogenic fungi. Soil solarization had beneficial effects on yield, bulb diameter, or incidence of pink root.
