  • This study was performed to determine the quality characteristics of Jeungpyun with the addition of soy yogurt (0%,3%, 6%, 9%, 12%). The proximate composition analysis showed that moisture contents of Jeungpyun were 49.87${\sim}$51.60%, and crush protein, lipid and ash contents were 2.58%, 0.21${\sim}$0.33% and 0.58${\sim}$1.05%, respectively. The pH ofJeungpyun was higher as the additive increased. Volume and symmetry index were higher as the additive increased, but uniformity index was no significant difference. L value and a value were the lowest in control group and increased with soy yogurt addition, while b value was decreased as amount of soy yogurt. Hardness, cohesiveness, gumminess were the highest in 9% group, springiness was the lowest in 9% group. In surface structure of Jeungpyun observed by SEM, cell size was the smallest and the cell uniformity was most regular in 12% group. According to sensory evaluation, appearance, taste and overall acceptance were highest in Jeungpyun with 9% soy yogurt. Therefore, Jeungpyun containing 9% soy yogurt was most preferable.

  • Seed, stem and sprout of F. tataricum were separately milled using the ultra fine mill under the same condition to investigate the effect of roasting or extruding on the particle size, microstructure and water solubility of dietary fiber. The mean particle size of MR (roasting) is increased in stem and sprout, and that of ME (extruding) is increased in seed, compared to that of control. The microscopic views of seed show that control has the spherical shape but ME the larger and irregular shape, and those of stem and sprout show that control has the needle like shape but ME more rounded shape. Water solubility index of ME is much higher than that of control or MR in seed, stem and sprout. It shows that seed, stem and sprout are damaged more in extruding than in roasting, and the starch and cell wall structure must be destroyed to change the water insoluble dietary fiber into the water soluble dietary fiber.

  • Recently there is growing Interest in LBS(Location Based Service) requiring real-time services and the spatial main memory DBMS for efficient Telematics services. In order to optimize existing disk-based multi-dimensional Indexes of the spatial main memory DBMS in the main memory, multi-dimensional index structures have been proposed, which minimize failures in cache access by reducing the entry size. However, because the reduction of entry size requires compression based on the MBR of the parent node or the removal of redundant MBR, the cost of MBR reconstruction increases in index update and the efficiency of search is lowered in index search. Thus, to reduce the cost of MBR reconstruction, this paper proposed the RSMBR(Relative-Sized MBR) compression technique, which applies the base point of compression differently in case of broad distribution and narrow distribution. In case of broad distribution, compression is made based on the left-bottom point of the extended MBR of the parent node, and in case of narrow distribution, the whole MBR is divided into cells of the same size and compression is made based on the left-bottom point of each cell. In addition, MBR was compressed using a relative coordinate and size to reduce the cost of search in index search. Lastly, we evaluated the performance of the proposed RSMBR compression technique using real data, and proved its superiority.

  • The investigation was undertaken to determin the altered function and structure of granulation tissue fibroblasts. Human granulation-tissue fibroblasts were cultured from periodontal chronic inflammatory lesions (SBI index : above 3) and compared with healthy gingival connective tissues fibroblasts a control(SBI index : below 1). Granulation tissue fibroblasts proliferated with a slower growth rate and exhibited larger cell size than control cells. Total protein profile of granulation tissue fibroblasts was almost identical to that of control cells with some exception. These results support tha theory that granulation tissue fibroblasts represent a distinct phenotype of fibrotic cells.

  • Polyurethane specimens were mainly composed of polyol, MDI, silicone surfactant, and water. The effects of ethylene glycol on the cell size, forming magnification, cream time, gel time, take free time, final free rising height, and reactive temperature were investigated. The cyclopentane was used for PU foam as a physical blowing agent. The components were hand-mixed at about 5000 rpm within 4 seconds at room temperature. The mixtures with various ethylene glycol contents were foamed in the wood mold. When the index of isocyanate was fixed, as the amount of ethylene glycol increased, cell size and thermal conductivity were decreased by about 5.1% and 14%, respectively.

  • This experiment was undertaken with the purpose of investigating effect of gibberellin on the growth and electron microscopic ultrastructure of hop(Humulus lupulus var. Hallertau) shoot apex. The results are as follows. 1) The growth of stem in the plots treated with GA(10, 25, and 50ppm) is more predominant than control. The leaves and cones of treated plots turn to pale green. 10ppm plot of GA treatment is the most effective in growth and yield than the others. 2) Under the GA-treated condition, it is believed that the nucleoplasmic index (NP) are higher than the control, and so nucleus, nucleolus, mitochondria, primary cell wall, middle lamella, and etc. tends to be larger than the control. 3) Mitochondria contained in the cell of shoot apex treated with concentration of 10ppm GA was seemed to increases in number and be larger in size than the control.

  • In this study, the performance of dye-sensitized solar cells with different thickness of the photelectrode film was simulated by using the electron-diffusion differential model. Through this simulation, the relationships between the thickness of the photoelectrode film and the performances (open-circuit voltage, short-circuit current density, and overall photoelectric-conversion efficiency) of cells were understood and the performances with different thickness of the photoelectrede film were also examined. For considering the refractive index in the liquid electrolyte and exploring the scattering effect of titanium dioxide particles with different sizes using the Mie light-scattering theory, the highest scattering effect of each particles was found out and the optimal size of the titanium dioxide particle was determined for light scattering in the photoelectrode film of dye-sensitized solar cell. Through experiment, the mixed titanium dioxide cell was better than the single titanium dioxide cell and generated a higher overall conversion efficiency because the optimal titanium dioxide particles in the phoelectrode film as light scattering.

  • The summary of a study of efficacy of Rose essential oil and Lavender essential oil against physiologic active change s of skin caused to surfactant is as follows. 1. In feed intake efficiency, there is more significant difference than control group, and then in water intake, there are significant differences between each group. It is presented that the water intake efficiency ratio of the group treated by Rose essential oil and Lavender essential oil is higher than all of groups to be participated in experiment. And then, the reason that the group treated Lavender essential oil is lower than any other group is needed water intake to be caused by stress. 2. As the result of serum analysis, in atherosclerotic index(A.I), the cholesterol of control group is higher than that of the group treated. As HDL cholesterol is activated, the dan1aged group is higher than control group, in LDL cholesterol the control group is higher. It is seen that the damaged group of the quantity of HDL cholesterol is lower frequently in A.I. This fact is presented that HDL cholesterol that cholesterol is exhausted is changed, because of the dan1aged group that replacement is activated. 3. As the observed result of alteration of sebaceous glands, it is appeared that the demage of sebaceous glands is destroyed in the damaged group. It is observed that epidermis of the group applied by Rose essential oil after treated surfactant is dry, secretion of phenomenon of water and sebum is appeared more. It is observed that the epidermis recovery of the group applied by Lavender essential oil after treated surfactant is insufficient. And then it is seen that stratum corneum is recovered and the quantity of sebum secretion is decreased. 4. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number and Mast cell's size is larger than the dan1aged group. It is presented that the Mast cell's number and Mast cell's size is larger than the damaged group, the Mast cell's size and quantity of the group treated by Rose essential oil and Lavender essential oil is decreased more.

  • Objectives: The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. Methods: The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impact fraction index was applied to calculate the avoidable burden in order to prioritize interventions. This index was calculated for theoretical, plausible, and feasible minimum risk level scenarios. The joint effects of the risk factors were then estimated for all the scenarios. Results: The highest avoidable burdens in the theoretical, plausible, and feasible minimum risk level scenarios for the non-use of child restraints on urban roads were 52.25, 28.63, and 46.67, respectively. In contrast, the value of this index for speeding was 76.24, 37.00, and 62.23, respectively, for rural roads. Conclusions: On the basis of the different scenarios considered in this research, we suggest focusing on future interventions to decrease the prevalence of speeding, the non-use of child restraints, the use of cell phones while driving, and helmet disuse, and the laws related to these items should be considered seriously.

  • Bubbles generated in water receive an upward buoyant force due to the density and pressure difference of the surrounding fluid. Additionally, the behavior, shape, and heat exchange process of bubbles vary depending on the viscosity, surface tension, rising speed, and size difference with the surrounding fluid. In this study, we modeled speed, and heat transfer of a high-temperature single bubble rising in a cylindrical water tank. For this purpose, velocity, and temperature of the bubbles were calculated using theoretical equations, to be compared with numerical simulation results. The numerical analysis was performed using a commercial software, and the stability of the numerical analysis with mesh size was confirmed through calculation of the grid convergence index. The numerical analysis of the rising speed and temperature of a single bubble showed the values to converge when the minimum cell size was 1/160 of the bubble diameter, and the temperature decrease was confirmed to be the same as that of the surrounding fluid within 0.05 seconds.
