USS(Ubiquitous Smart Space) give services, that fit in with customer's goal, by cognizing various situations that happens in a space and cooperating autonomously objects or services in a space. In USS, U-Safety is a system that cognizes more exact situations with multiple sensors in USS, deals with this and take proper actions. When men reason on situations objectively, it is most ideal that image data among collected data with used various sensors in U-Safety. A senter collects a lot of image data from image input devices equipped in various points and work a multiple situation cognition and inference that are based on this. So, senters spend many resources for processing massive data. This paper proposes hierarchical image processing method that does the first situation cognization in image input devices, blocks only points that situation cognization possibility is high among a total image, and transfers to senters. It improves the efficiency of smooth situation cognization by reducing resources that a senter spends on image processing. So, it reduces proportion of image data in U-Safety.

Current desulfurization and denitrification technologies have reached a considerable level in terms of reduction efficiency. However, when compared with the simultaneous reduction technology, the individual reduction technologies have issues such as economic disadvantages due to the difficulty to scale-up apparatus, secondary pollution from wastewater/waste during the treatment process, requirement of large facilities for post-treatment, and increased installation costs. Therefore, it is necessary to enable practical application of simultaneous SOx and NOx treatment technologies to remove two or more contaminants in one process. The present study analyzes a technology capable of maintaining simultaneous treatment of SOx and NOx even at low temperatures due to the electrochemically generated strong oxidation of the wet-pulse complex system. This system also reduces unreacted residual gas and secondary products through the wet scrubbing process. It addresses common problems of the existing fuel gas treatment methods such as SDR, SCR, and activated carbon adsorption (i.e., low treatment efficiency, expensive maintenance cost, large installation area, and energy loss). Experiments were performed with varying variables such as pulse voltage, reaction temperature, chemicals and additives ratios, liquid/gas ratio, structure of the aeration cleaning nozzle, and gas inlet concentration. The performance of individual and complex processes using the wet-pulse discharge reaction were analyzed and compared.

Objectives : This study was to investigate the effectiveness of bee venom phamacopuncture complex therapy on the sequelae of peripheral facial palsy. Methods : We observed the effectiveness of bee venom pharmacopuncture complex therapy on three patients who have residual symptoms of Bell's palsy although early stage(0 to 3months) elapsed. H-B grade and Yanagiha's total score was used for evaluating the patient. Results : 1. Deviation of the bee venom therapy on the sequelae of peripheral facial palsy, One patient was improved from 19 to 39, another patient was improved from 25 to 40, the third patient was improved from 15 to 26 on Yanagiha's total score. 2. In the bee venom therapy on the sequelae of peripheral facial palsy, compared with baseline, at final, H-B grade and Yanagiha's total score was increased. Conclusions : Bee venom phamacopuncture can be available for relieving residual symptom of bell's palsy after the early stage.

The numerical simulations of flowfield and pollutant dispersion over two-dimensional hills of various shapes are described. The Reynolds-averaged Wavier-Stokes equations and concentration diffusion equation based on the gradient diffusion theory have been applied to the atmospheric shear flow over the bell-shaped hills which are basic components of the complex terrain. The flow characteristics such as velocity profiles of the geophysical boundary layer, speed-up phenomena, mean pollutant concentration profiles are compared with experimental data to validate the present numerical procedure and it has been found that the present numerical results agree well with experiments and other numerical data. It has been also found that the distributions of ground level concentration are strongly influenced by the source location and height.

Objective : This study was to report Bell's palsy patients with severe pain back of the ear treated by Bee Venom Pharmacopuncture therapy. Methods : The patients was treated by Bee Venom Pharmacopuncture therapy to relieve the severe pain back of the ear. Visual Analog Scale(VAS) was used as an outcome measurement. Results : After Bee Venom Pharmacopuncture therapy, VAS were decreased at all case. Conclusion : Bee Venom Pharmacopuncture therapy can be available for relieving severe pain back of the ear even inducing insomnia.

The purpose of this study was to investigate the effects of clothing pressure of Bell-bottom slacks according to various movements of the legs In this study, movements of legs were classified by M1, M2, M3, M4, M5, M6. (M1: erecting Position, M2: Setting Position, M3: Stepping Pssition, M4: Leapfrogging Position, M5: Sit-on-one's Position, M6: Traditional noble-sitting) The results were as follows: clothing pressure was very different according to the movements of the legs and was in order M4>M5>M6>M2>M3>M1. Particually, clothing pressure in the knee point is the highest in the M4 movement $(550.81g/cm^{2})$.

A study of the effects of multibanded orthodontic appliances on the oral lactobacilli was conducted on 41 multibanded group and 41 caries free group. The following conclusions were obtained. 1. In multibanded group, the average count of lactobacilli per milli-liter of saliva showed about 219,300 in male and 254,100 in female. In caries free group, the mean count of lactobacilli per milli-liter of saliva showed about 66,700 in male and 68,500 in female, Therefore, the average of lactobacilli in multibanded group was much higher than that of the caries free group in both sexes. 2. The average of all the types of lactobacilli colonies (Disk-type, Bell-type, Y-type) in multibanded group was much more than that of caries free group. 3. Multibanded orthodontic appliances were found to sufficiently alter oral environment to significantly affect disk-types and total counts in both sexes and bell-type in female, at $1\%$ level of confidence. But changes in bell-type and y-type, in male, were considered to be significant at $5\%$ level of confidence.

A three-dimensional linear model and the Advanced Regional Prediction System (ARPS) were used to simulate parabola-shaped disturbances and clouds in the lee of a bell-shaped mountain. The ARPS model was compared in the x-y plane against the linear model's analytic solution. Under similar conditions with the linear theory, the ARPS produced well-developed parabola-shaped mountain disturbances and confirmed the features are accounted for in the linear regime. A parabola-shaped cloud in the lee of an isolated bell-shaped mountain was successfully simulated in the ARPS after 6 hours of integration time with the prescribed initial and boundary conditions, as well as a microphysical scheme.

The numerical simulations of flow and pollutant particle dispersion are described for two-dimensional bell shaped hills with various aspect ratios. The Reynolds-averaged incompressible Navier-Stokes equations with low Reynolds number $\kappa$-$\varepsilon$ turbulent model are used to simulate the flowfield. The gradient diffusion equation is used to solve the pollutant dispersion field. The code was validated by comparison of velocity, turbulent kinetic energy, Reynolds shear stress, speed-up ratio, and ground level concentration with experimental and numerical data. Good agreement has been achieved and it has been found that the pollutant dispersion pattern and ground level concentration have been strongly influenced by the hill shape and aspect ratio, as well as the location and height of the source.

Beating phenomenon which is generated by two closely located natural frequencies is one of research tenet for King Song-Dok bell. In this paper, we investigate the vibration shape of these natural frequencies using very extensive experimental data. Vibration signals are sampled at 108 points around the bell using accelerometers. Measured signals are anlayzed in time and frequency domain. Twelve natural shapes under 800Hz are plotted.
