Five-brown-rice-variety, Akibare, Odaebyeo, Taebaegbyeo, Nonglim Na 1 and Hankangchalbyeo, was prepared and examinated the hydration kinetics and the cooking qualities. Before the hydration the L/W ratio of raw Taebaegbyeo was the biggest value among the five brown rices. The water uptake was directly proportional to the square root of soaking time. During the hydration water uptake of high yielding brown rices was bigger than those of traditional brown rices among the nonglutenious varieties but waxy brown rices were not. Generally volume increase constant was directly proportional to the water uptake constant, which were different a little with brown rices was hydrated which was inversed proportional to the water uptake degree. According to the instrumental result using the rheometer of cooked brown rice with increased soaking times that was decreased the hardness and was increased the adhesiveness. The sensory evaluation test indicated that the hardness and the stickiness value of cooked brown rices were proper after 15-hour-soaking time and it was identical result to the instrumental result using the rheometer.

This paper is results of analyzing the characteristics of rainfall triggering landslides and geometry of slopes, caused by the heavy rainfall and antecedent precipitation by Typhoons Ewiniar and Bilis at Chuncheon area in Gangwondo around July in 2006. As results of analyzing the characteristics of rainfall, landslides in 131 sites were found to happen due to the heavy rainfall having the maximum intensity of rainfall in an hour during July 15 and antecedent precipitation during July 12 to 14 causing the ground to be weak by increasing the degree of saturation previously. From results of analyzing the geometrical characteristics of 131 slopes where landslides occurred, the slope width were in the range of 6~10m. The average slope length and angle were 46m and $51.8^{\circ}$, which was relatively steep slope, respectively. Landlises occurred in the elevation of 400 - 500 m with the most probable frequency.

Accurate and robust load forecasting model plays very important role in power system operation. In case of short-term electric load forecasting, its results offer standard to decide a price of electricity and also can be used shaving peak. For this reason, various models have been developed to improve accuracy of load forecasting. This paper proposes a newly forecasting model for weather sensitive season including temperature and Cooling Degree Hour(C.D.H) data as an input. This Forecasting model consists of previous electric load and preprocessed temperature, constant, parameter. It optimizes load forecasting model to fit actual load by PSO and results are compared to Holt-Winters and Artificial Neural Network. Proposing method shows better performance than comparison groups.

This studies were conducted to select optimal enzyme that produced hydrolysate from soybean, and to evaluated functionality of hydrolysate. Soybean powder was suspended with water and hydrolyzed by seven commercial proteases. Hydrolysate produced with protease from Bacillus subtilis showed the highest inhibition effect on the activity of angiotension converting enzyme(ACE), and the condition of enzymatic hydrolysis was 5cA substrate concentration, 0. l% enzyme concentration, 4 hour hydrolysis time. Under above optimum condition, soybean was hydrolyzed with protease from Bacillus subtilis yielding a DH (degree of hydrolysis) of about 49%. Hyrophobicity of hydrolysate was not correlated with the inhibition effect on ACE activity. The functionality of hydrolysate was significantly influenced by pH. Solubility of hydrolysate at alkali solution was greater than that at acidic solution.

The published works on steam curing effect have been generally concentrated on the subject, "compressive strength". However a practical test for durable steam curing concrete products has not been performed in domestic. In this study, the maximum temperature of steam is considered as a major variable to investigate the freezing and thawing resistance of the steam curing concrete. All of the specimen were cured for 24 hours which included presteaming 4 hour. Finally we found that the most effective curing condition is the case of one-day and 14-day specimens after the 24 hours steam curing at $74^{\cire}C$ degree curing temperature. It is also found that the durability of one-day samples are much weaker than those of 14-day samples. Consequently, we can conclude that the samples that produced immediately after a steam curing are more possible to deteriorate from the freezing and thawing environment.vironment.

This study was attempted to enhance the contents of dietary fiber and minerals of cooked rice by adding four different levels of carrot juice in cooking water (0%:A. 10%:B. 20%:C. 30%:D). The degree of gelatinization and retrogradation, sensory evaluation. and in vitro digestion ratio were tested. These results concluded that the rice cooked with 10～20 % of carrot juice in cooking water was quite acceptable. the optimum cooking conditions fur the rice were one hour presoaking time, 160% cooking water to rice ratio. 20 minutes heating time and 10 minutes steamed cooking.

This Study intends to find out the subjective symptom of Construction Business Worker caused by chemical material exposure, also willing to research how much they are exposed to VOCs(Volatile Organic Compounds) and under how much harmful circumstance they are working. As the results, the job group among construction business workers which is most highly dangerous degree to be taken ill of Multiple Chemical Sensitivity is Interior Worker, next following by order of Clerical Worker, Exterior Worker. According to this result, the continuous exposure in high density must be prevented by the measures for Interior Worker also to be bestowed a compulsory break during working hour for regular exposure to the open air,

The Purposes of this study are first to develop the teaching and learning plan for the dress part in high school's Home Economics by the application of the values clarification theory then to apply it to the classroom activities. and lastly to analyze its effects. We developed the master plan for teaching and learning, and developed the 12 hour sub plans including 7 activities and learning materials. The effects of the teaching are as followings: First, When the self-esteem was compared with the whole classes, there was no difference between the twos, but a boy and a girl who were observed as not making a value-oriented life marked higher score in answering the self-esteem. Second. It was found that values clarification theory made student's degree of participation and interest higher and helped them to choose their dresses in the real life.

In order to investigate the effect and reliability coming up to properties of the matter due to the change of solid structure in dielectrics, the effect of dielectric characteristics for thermal treated LDPE film was made researches. Specimens of LDPE with thickness 100 [$\mu\textrm{m}$] were investigated into the change of solid structure by ageing. Thermal treated specimen were made, that were after applying heat at 100 [$^{\circ}C$] for 1 [hour] \circled1 air-cooled specimen slowly, \circled2 water-cooled specimen under the ,com temperature, \circled3 liquid nitrogen gas-cooled specimen rapidly. With specimen of thermal treated three types turn out and original, it was for dielectric characteristics to be experimented in the temperature range of 20~120 [$^{\circ}C$], frequency range of 30~1.5${\times}10^5/$[Hz], appling voltage from 300 to 1500[㎷]. Consequently, the degree of crystallinity was changed with 49~57 [%] according to the thermal treatment. In case of frequency, 100 [Hz], on the thermal dependance in dielectric characteristics, tan decreases due to cooling method.
