The objective of this is to experimentally investigate the effect of mixed jet on the oxygen transfer characteristics with the primary nozzle area ratio of an annular nozzle ejector for the application of a microbial fuel cell. A direct visualization method with a high speed camera system was used to capture the horizontal mixed jet images, and a binarization technique was used to analyze the images. The clean water unsteady state technique was used for the oxygen transfer measurement. The air-water mixed jet discharging into a water tank behaved similar to a buoyancy or horizontal jet with the primary nozzle area ratio. It was found that an optimum primary nozzle area ratio was observed where the oxygen transfer performance reached its maximum value due to the decrease of air volume fraction and the increase of jet length and air bubble dispersion.

Tsutakawa(1988) proposed a mixed model for using empirical Bayes method to study the geographic variability in mortality rates of a disease. In particular cases of the analysis in mortality rate, we need to consider the effect of time. If observed data are collected annually for the time period, then time effect will be emphasized. Here, an extended model for estimating the geographic effect and the mortality rates of the disease with time effect is proposed.

The effect of mixed onion pills on body composition, blood pressure, and concentrations of blood glucose and lipids were studied in 10 men ($38.11{\pm}2.82$ years old). The mixed onion pills was produced by mixing quercetin, onion, mulberry leaves and buckwheat. Ten volunteers (male, BMI 23.0~35.4 kg/$m^2$) were chosen for this study. The volunteers consumed 1.2 g of mixed onion pills (containing about 30 mg of quercetin) per day for 2 months. The administration of the mixed onion pills did not produce any weight and BMI changes in the subjects. The systolic blood pressure and the level of blood glucose were slightly lowered by the supplementation of the mixed onion pills. After 2 months both the concentration of plasma triglycerides and total cholesterol of the subjects were lowered by 12.4% and 5.0%, respectively (triglyceride; pre $251.67{\pm}45.63$ mg/dL vs. post $220.44{\pm}44.67$ mg/dL and total cholesterol; pre $207.25{\pm}10.39$ mg/dL vs. post $196.63{\pm}10.47$ mg/dL, p<0.05). These results suggest that the mixed onion pills may possibly lower the level of plasma lipids in overweight or obese men (BMI greater than 23 kg/$m^2$).

To experimentally research out the effect of 'Hagocho-San' used for liver disease on the clinical treatment of oriental medicine, I induced liver damage rats by thioacetamide and dosed the extracts orally and measured the activity rate of GOT, GPT, ALP and LDH. The following results were obtained: 1) GOT activity was more decreased in the experimental group than in the control group. Extracts from mixed decoction was more efficacious than those mixed form of the extracts after individual decoction. Extracts from decoction showed continuous significance after 48 hours on, but mixed form of extracts after individual decoction was significant only after 48 hours and 96 hours. 2) GPT activity was more decreased in the experimental group than in the control group. Extracts from mixed decoction was effective after 48 hours on but mixed form of extracts after individual decoction was significant after 48 hours and 72 hours. 3) ALP activity was more decreased in the experimental group than in the control group. Extracts from mixed decoction was more efficacious than the mixed form of extracts after individual decoction and significance was verified after 72 hours on. 4) The significance of LDH activity in the extracts from mixed decoction was revealed after 72 hours and 96 hours but mixed form of extracts after individual decoction showed significance 72 hours later. 5) From the above results, it was showed that 'Hagocho-San' extract was effective on liver disease and extracts from mixed decoction was more effective than mixed form of extracts after individual decoction.

This study was performed to use fiber mixed soil which has clayey soil or sandy soil with fibrillated fiber or monofilament fiber on purpose of construction materials, filling materials, and back filling materials. In addition, this study was conducted to analyze strength properties and fiber reinforcing effect with fiber mixed soil by direct-shear test. In case of fibrillated fiber mixed soil, the more quantity of fiber was in both cohesive soil and sandy soil, the larger shear stress was in respective step of normal load. The respective mixed soil at 0.5% and 0.1% mixing ratio of monofilament fiber mixed soil showed maximum shear stress. According to unconfined compression or direct-shear test, making specimen of the monofilament fiber mixed soil, it is required to be careful and stable mixing method, while it is expected that monofilament fiber mixed soil doesn't increase strength.

Zinc soap and Zn/Ba mixed metal soap were synthesized and PVC plastisol with mixed metal soap and various costabilizers were also synthesized with good structures and characterized by IR and $^1H$-NMR. The IR spectrums and $^1H$-NMR spectrums of the synthesized soaps were in very good accordance with the structures proposed by earlier workers. In using phosphite as a costabilizer, TIDP phosphite was shown to be the excellent thermal stabilization effect at the low temperature and TNPP phosphite was shown to be the excellent thermal stabilization effect at the high temperature. In case of antioxidant, it was revealed that antioxidant was not effective in the low temperature thermal stabilization effect while highly effective in the high temperature thermal stability. $NaClO_4$ solution with sorbitol solvent had the best thermal stabilization effect among $NaClO_4$ solution series at low and high temperature.

The purpose of this study was to investigate the consumption and perception on the effect of cooked rice mixed with multi-grain (CR-MG). Reason for like and dislike, intake frequency and variables related with the satisfaction of CR-MG were also investigated. The data for the analysis was collected from 315 adults who were residing at Seoul${\cdot}$Kyeonggi and Kangwon area and analyzed by the SPSS 11.0 program. The result showed that 84.8% of the respondents consumed CR-MG, showing significant difference by gender and occupation (p<0.05). It also revealed that they consumed it knowing their effect, showing significant difference by all general characteristics except for resident area and BMI, respectively. Kind of multi-grain (MG) mixed with cooked rice was high in the order of SoRiTae (80.1%) > brown rice (73.4%) > black rice (72.7%) > waxy rice (61.0%), respectively. As for the mixing type of MG, 61.4% of the respondents preferred non-mixed product rather than pre-mixed product. 2 or 3 kinds were preferred numbers of MG mixed with rice, showing significant difference by age (p<0.001) and marital status(p<0.05), respectively. 59.9% of the respondents answered 'high nutritive value more than polished rice' as the major reason for like, whereas 31.3% answered 'greatly rough more than polished rice' as that for dislike, respectively. By the use of multiple regression analysis, it revealed that health was the most significant variable which affect the satisfaction of CR-MG. From these results, it was suggested that in view of the high consumption and intention to continue the intake of CR-MG, following studies should be conducted to improve the preference of CR-MG.
