        This study was conducted to evaluate children’s purchase behavior (frequency of snack consumption and purchase) and preference for high protein snack products developed for weight control and nutritional balance. A total of 80 elementary school students (from the 3rd to 6th graders) in the Gyeonggi-do learning center were participated and 76 were used for the analysis. The most common response for liking snacks was taste (71.4%), and the most preferred types of snacks were chips (42.1%) and puff snacks (34.2%). The highest frequency of snack ingestion was 1-3 times per week (48; 63.2%), and the main purchasers were parents (65.8%). Cheese, corn and chili flavors were more preferred than the control, while yogurt taste was slightly less preferred than the control. The results of this study showed the possibility of commercialization of new protein snacks according to children’s seasoning preference and provide the insights into the snack preferences of children as main consumers.

        This study examined the effect of outside temperature on the properties of high-strength concrete to determine conditions for four-season construction. With 20 ℃ as the reference temperature, 20, 30, and 40 ℃ were set as hot weather conditions, and 5, -10, and –20 ℃ as cold weather conditions. Properties as the effect of outside temperature on compressive strength of high-strength concrete was studied.

        Studies on the lattice girder of the cross sectional form and construction works through laboratory experiments have been performed. The numerical analysis for structural behavior such as deflection and stresses on the lattice girder, however, are insufficient. In this study the stiffness of a lattice girder was examined by using MIDAS.

        In this study, the use of natural raw material and an inorganic binder such as vermiculite, perlite board prepared by using the inorganic was to prepare a switchboard casing. The characteristics of the basic physical properties such as compression strength of a board made of the inorganic material to the pre-study evaluation therefor.

        To obtain the risk assessment of hazardous materials in Rehmanniae Radix Preparata, the residual pesticides and heavy metals in samples on the Korea and China are surveyed. Group Ⅰ(BHC-δ, BHC-β, Fenitrothion, Penthoate, Endosulfan-α, Dieldrin, Endosulfan-β and Endosulfan-sulfate), Group Ⅱ(BHC-γ, Aldrin, DDD, DDT-p,p Permethrin and Fenvalerate), Group Ⅲ(BHC-α, Chlorpyrifos, Tolyfluanid, Captan and DDT-o,p) and Group Ⅳ(Quintozene, Vinclozolin, DDE and Chlorfenapyr) could analysed on gas chromatography-ECD for evaluation of residual pesticides. Qualified detection concentration on the GC-ECD are 0.45 ng/g~2.50 ng/g. Group Ⅰ, Group Ⅱ, Group Ⅲ and Group Ⅳ are not detected in Rehmanniae Radix Preparata on the Korea and China. Concentration of As, Cd and Pb in Rehmanniae Radix Preparat. on the Korea are 3.06%, 7.00% and 5.78% for Korea Food & Drug Administration(KFDA). Concentration of As, Cd and Pb in Rehmanniae Radix Preparata. on the China are 5.16%, 5.33% and 6.50% for Korea Food & Drug Administration(KFDA). The hazardous materials in Rehmanniae Radix Preparata on the Korea and China were verified the safety of the residual heavy metals and pesticides compare with Korea Food & Drug Administration (KFDA) advisory level.
