This study conducted a questionnaire survey of family restaurant employees in Seoul on their satisfaction and preference in working uniforms, and analysed the result to suggest adequate designs to serve the purposes of uniforms. The result is as follows - First, many pointed out a need to improve generally showing a low satisfaction with varying degrees according to sexes and ages. More women complained about colors, designs, materials and sizes than men did, and young employees in their twenties wanted better designs, colors and sizes in the order while those in their thirties and forties were dissatisfied mostly with materials. The need fur the improvement was focused on function and designs, and as for uniform materials, perspiration absorbency had the highest level of dissatisfaction. Second, about 40% of the respondents said the skirt width, pants length, and sleeve width were trio small or too big, therefore it is vital to improve uniform sizes. Third, the employees on duty felt uncomfortable mostly when they sat, and the neck and armhole parts were the most uncomfortable. The most easily tainted parts were in the order of the collar, front hem, and sleeve seam for upper garments, and the hip, bottom hem, and pleats for lower ones. Therefore it is required to develop functional uniforms considering the body features and momentum. Fourth, the most preferred material was that guaranteed easy movement and good air-permeability, and colors were in the order of white, beige and black for upper garments, and black, beige and blue for lower ones. And plain, natural and stripped patterns were preferred by both men and women. As seen so far, restaurant employees were mostly dissatisfied with the design, movement, and function of their uniforms demanding functional ones made of better and comfortable material. Uniform designs were suggested based on the analysis of the demonstrative rese.

Weeding in orchards is closely associated with productivity and quality. The customary weeding process is both labor-intensive and time-consuming. To solve the problems, there is need for automation of agricultural robots and machines in the agricultural field. On the other hand, orchards have complicated working areas due to narrow spaces between trees and amorphous terrain. Therefore, it is necessary to develop customized robot technology for unmanned weeding work within the department. This study developed a path generation and path control method for unmanned weeding according to the orchard environment. For this, the width of the weeding span, the number of operations, and the width of the weeding robot were used as input parameters for the orchard environment parameters. To generate a weeding path, a weeding robot was operated remotely to obtain GNSS-based location data along the superheated center line, and a driving performance test was performed based on the generated path. From the results of orchard field tests, the RMSE in weeding period sections was measured at 0.029 m, with a maximum error of 0.15 m. In the steering period within row and steering to the next row sections, the RMSE was 0.124 m, and 0.047 m, respectively.
This study analyzed the working conditions and problems of screen fire shutters in the Goyang Bus Terminal fire based on the fire investigation results. At that time, screen fire shutters in the 1st basement, which was under construction, did not work because the power was shut off. Four screen fire shutters in the 1st and 3rd floor did not work despite the power not being shut off. The following problems related to a screen fire shutter were found: shutting off the power to screen fire shutters for the fire compartment on each floor, even when the fire compartments were changed in each area; installing an integral type screen fire shutter without any regulations, installing a two-stage screen fire shutter in a place not related to obstacles during evacuation; stopping the function of the screen fire shutters for a fire compartment on each floor after a combustible sandwich panel was comparted; installing a screen fire shutter over 10 meters in width, in which its performance was not verified; and no safety control standards for reinstalling or maintaining a screen fire shutter.

There are increasing demands for the producing and breeding new domestic riding horses for the vitalizations of horse riding industry in Korea, according as 'Horse Industry Support Act' became. In this study, we were to develop the functional relation through the conformation comparison & body composition analysis. 76 heads of 5 breeds utilized for riding horses in Korea were used and their body measurements on 12 items were measured and cluster analysis was conducted to determine the correlation relation among them. The measurements were standardized that (height, croup height, pelvis length), and (hip width, width of pelvis) were highly correlated. In these results of the decision tree, we confirmed to classify the breed type determination by their body measurements (hip height, hip width, head length, croup height). This result can be used as basic data for the development of horse type determination (racing, riding, Riding for the Disabled, Working, or fattening) through the analysis of body composition, and be utilized as the basic data for the producing and breeding new domestic riding horses through the 3D Stereosocpic image system analyze.
The importance of leaf area as related to transpiration and photosynthesis is generally recognized. In general, a compound leaf of soybean consist of one main leaflet and two side leaflets from each node of the stem. Takahashi and Fukuyama (1919) classified soybeans into three types, namely the long leaf type, round leaf type, and intermediate type, in which the last one had round leaves at the base and long leaves in the upper part of the stem. Nagai (1925) and Takahashi (1935). dealt with the genetics of the leaf form and association with other characters. The closely relationships, the correlation coefficients from 0.64 to 0.73, were shown between the leaf area and the soybean yield in the experiments by Nagai (1942). Nagata (1950) also tested the varietal differences of the variation of leaf length and its ratio to the leaf width on the nodes of stem, and finally divided varieties into five types. Three methods of measuring area of strawberry leaves were used by Darrow (1932). The first involved determining a factor to be used with length or length ${\times}$width measurements. The second method involved placing leaves on pieces of cardboard of known area cut to the shape of the leaves. Direct use of the planimeter on intact leaves was Darrow's third method. Miller (1938) enumerated several methods to determine the leaf surface area in plants, some of which were extremely laborious and required removing leaves from plants. They included tracing outlines of leaves on paper and measuring the enclosed area with a planimeter or cutting out the traced areas and comparing the weights obtained with the weight of a known paper. Another method involved placing the form of the leaf on sensitized paper with the area being determined by measuring or weighing as above. Miller further stated that the photoelectric cell can also be utilized to estitmate leaf area. Working with field beans, Davis (1940) found that 0.004517 (length ${\times}$ width) of the center leaflet was the most nearly accurate of four methods attempted. A simple procedure to measure leaf area in corn was devised 1 y Montgomery (1911) and used by Kiesselbach (1950). The formula was length ${\times}$ width ${\times}$ 0.75. Stickler et al. (1961) have successfully used length times width ${\times}$ 0.747 to estimate area of grain sorghum leaves. Bhan and Pande(1966) has also used length ${\times}$ width ${\times}$ 0.802 to determine leaf area of rice varieties. The main objectives of the present investigation were to develop an accurate, rapid method to determine leaf area in soybean varieties and to examine certain data associated with leaf area determinations.

In this study Al-doped ZnO (AZO) thin films have been fabricated on Eagle 2000 glass substrates at various substrate temperature ($100{\sim}500^{\circ}C$) and working pressure (10 ~ 40 mTorr) by RF magnetron sputtering in order to investigate the structural, electrical, and optical properties of the AZO thin films. The obtained films were polycrystalline with a hexagonal wurtzite structure and preferentially oriented in the (002) crystallographic direction. The AZO thin films, which were deposited at $T=300^{\circ}C$ for 10 mTorr, shows the highest (002) orientation, and the full width at half maximum (FWHM) of the (002) diffraction peak is $0.42^{\circ}$. The lowest resistivity ($2.64{\times}10^{-3}\;{\Omega}cm$) with the highest cartier concentration ($5.29{\times}10^{20}\;cm^{-3}$) and a Hall mobility of ($6.23\;cm^2/Vs$) are obtained in the AZO thin films deposited at $T=300^{\circ}C$ for 10 mTorr. The optical transmittance in the visible region is approximately 80%, regardless of process conditions. The optical band-gap depends on the Al doping level as the substrate temperature increases and the working pressure decrease. The optical band-gap widening is proportional to cartier concentration due to the Burstein-Moss effect.

Geological dynamic hazards during coal mining can be caused by the failure of a composite system consisting of roof rock and coal layers, subject to different loading rates due to different advancing velocities in the working face. In this paper, the uniaxial compression test simulations on the composite rock-coal layers were performed using $PFC^{2D}$ software and especially the effects of loading rate on the stress-strain behavior, strength characteristics and crack nucleation, propagation and coalescence in a composite layer were analyzed. In addition, considering the composite layer, the mechanisms for the advanced bore decompression in coal to prevent the geological dynamic hazards at a rapid advancing velocity of working face were explored. The uniaxial compressive strength and peak strain are found to increase with the increase of loading rate. After post-peak point, the stress-strain curve shows a steep stepped drop at a low loading rate, while the stress-strain curve exhibits a slowly progressive decrease at a high loading rate. The cracking mainly occurs within coal, and no apparent cracking is observed for rock. While at a high loading rate, the rock near the bedding plane is damaged by rapid crack propagation in coal. The cracking pattern is not a single shear zone, but exhibits as two simultaneously propagating shear zones in a "X" shape. Following this, the coal breaks into many pieces and the fragment size and number increase with loading rate. Whereas a low loading rate promotes the development of tensile crack, the failure pattern shows a V-shaped hybrid shear and tensile failure. The shear failure becomes dominant with an increasing loading rate. Meanwhile, with the increase of loading rate, the width of the main shear failure zone increases. Moreover, the advanced bore decompression changes the physical property and energy accumulation conditions of the composite layer, which increases the strain energy dissipation, and the occurrence possibility of geological dynamic hazards is reduced at a rapid advancing velocity of working face.
The interfacial structures of ZnSe/GaAs which were grown by single chamber MBE at $300^{\circ}C$ were investigated by high resolution transmission electron microscope working at 300 kV with resolution of 0.18 nm. The interfaces of ZnSe/GaAs whose thickness is 2,700 nm are wavy and extensive stacking faults were formed in ZnSe epilayer but the interfaces maintained the coherency with the substrate GaAs. The stacking faults are formed in {111} planes and their sizes are $10{\sim}20nm$ in length and two or three atomic layer in width with the density of $10^9/cm^2$. Micortwins and moire fringes are also observed. However. in 10 nm ZnSe epilayer, the interfaces are pseudomorphic and only moire fringes are observed in local areas. The cylindrical defects which are perpendicular to the interface with $50{\sim}60nm$ in length, were observed with the interval of 50 nm at ZnSe/GaAs interfaces in 2,700nm epilayer. The origin and character of these defects are unknown, however, they played a role of producing the structural defects at the interfaces.
The study purpose was to increase Han-bok's convenience by changing materials while maintaining keep the traditional Han-bok style. For this purpose we surveyed actual Han-Bok wearers about the inconveniences of its form and design by combining knit with Han-bok. On the basis of this survey, we present a practical design for use in daily fife. Responding to the question about Jeo-Go-Ri(jacket), most respondents preferred a Han-bok which stressed elasticity by utilizing knit on Jeo-Go-Ri's front and back body line(JD1, JD4). For the question about ann holes, most respondents liked a design which substituted knit materials for Sam-hoi-jang(colorful strips) to ensure ease of use and shorten both the width and length of the breast-tie(JD2, JD3). For the sleeve edge, they preferred a design which solved the difficulties of rolling up the sleeve when working ($JD2{\sim}JD5$). Regarding the most inconvenient aspect of wearing Chi-mas(skirts), the respondents indicated tightening of the breast and an uncomfortable feeling due to the skirt length. This suggested that the waist of the vest should be lengthened to avoid the feeling of pressure(CD2, CD5). Regarding changes to the skirt shape the respondents preferred buttons and hooks rather than using skirt strings(CD4, CD5).
