  • Radial variations of resin canals in Pinus koraicnsis and Larix kaempferi which were cultivated-commercial trees in Korea, were examined to understand the characteristics of wood with light microscopy. Both species showed significant differences in the number of vertical resin canals along the radial direction from pith to bark. In Larix kaempferi, the diameters of horizontal resin canals and the number of epithelial cells showed a clear variation in radial direction. Namely, significant differences in the characteristics of the resin canals and epithelial cells were found in juvenile and adult woods. Consequently, it was concluded that the characteristics of resin canals can he used to estimate the wood quality.

  • 마그네트론 스퍼터링으로 Al과 Al 합금(Al-3wt%Si, Al-10wt%Si) 박막을 코팅하였다. 기판은 냉연강판과 Si 웨이퍼를 사용하였으며 알코올과 아세톤으로 초음파 세척 후 진공용기에서 플라즈마 청정을 실서히였다. 시편 청정이 끝나면 기판은 0, 30, 45, 60, 90도의 다양한 각도로 고정시켜 Al과 Al 합금 박막을 코팅하였다. 빗각 증착 기술(Oblique Angle Deposition: OAD)은 입사증기가 기판과 수직하지 않게 기울여 코팅하는 방법으로 조직을 다양하게 제어할 수 있다. 빗각으로 코팅한 순수한 Al 박막의 경우, 동일한 두께의 박막보다 반사율 및 표면조도, 내식성이 향상되는 결과를 얻었다. 따라서 본 연구에서는 빗각 및 Si 함유량이 반사율 및 표면조도, 내식성에 미치는 영향을 비교 분석하였다. 기판의 위치에 따른 변화를 관찰하기 위해 시편은 좌, 우, 중간으로 구분하여 분석하였다. 단일층 박막의 경우 타겟과의 거리에 따른 두께 편차가 발생하였으며 이러한 두께 편차를 해결하기 위한 방법으로 동일한 각도를 유지하며 반대 방향으로 회전시켜 다층구조로 박막을 제조하였다. Si 함유량 및 빗각에 따른 반사율 및 표면조도를 분석하였으며 내식성 평가를 위한 염수 분무 테스트도 실시하여 각각의 공정 변수에 따른 결과를 비교 분석하였다.

  • The methods of prelimiuary noose prediction by Janssen, Buiten, etc are introduced. The distribution of noise levels in newly built ships are investigated. A new procedure for noise prediction is proposed which reflects the results of the investigations. The dominant noise souroes(M/E, D/G) are regarded as one virtual source. The structureborne transmission loss are divided into vortical and horizontal components and the latter component depends on the number of decks as well as the number of frames. The all considered cabins are standardized with typical cabins which have the same acoustic properties. The measured and predicted noise levels are compared In the tables.

  • The purpose of this paper is to examine the characteristics of firms relocation into or out of Busan Region. Especially, it analyses the relation between relocated regions, firms' sizes and industrial sectors of the relocated firms systematically. For this, examinations of former studies about firm relocations, forming of analytical framework for systematic investigation were done. In short, this analysis figures out the correlation between the firms' characteristics and relocations.

  • This paper proposed a recognition method of english calling card using both 4-directed contour tracking algorithm and enhanced ART1 algorithm. After we extract candidate character string region using horizontal smearing and 4-directed contour tracking method, we extract character string region through comparison of character region and non-character region using horizontal and vertical ratio and area in english calling card. In extracted character string region, we extract each character using horizontal smearing and contour tracking algorithm, and recognize each character by enhanced ART1 algorithm. The proposed ART1 algorithm is enhanced by dynamic control of similarity using fuzzy sum connective operator. The result indicate that the proposed method is superior in performance.

  • In this paper, we propose a new approach to detect candidate area of vehicle license plate using compounded color and vertical edge information it's own. Also, we propose a verification course, to compressed image generated by Fast DCT, using SVM to increase accuracy of extracted vechicle license plate area. Proposed method is consider that vehicle's position, become a object of it's license plate recognition, has various angle, scale and include enough environment informations. As a experimental results, proposed method shows a superior performance compared with the case that not includes verification course using SVM.

  • The skewness of near-bottom velocity distribution caused by the nonlinear interaction of the second order waves proposed by Wells (1967) has been re-evaluated. The direction of cross-shore sediment transport was related to the sign of the third moment (skewness) of velocity distribution, and a new concept of neutral depth which can explain the recovery of beach equilibrium after a disturbance is suggested. The seasonal change of beach profile due to the change of wave condition (storm-swell profile) is interpreted in terms of nonlinear interaction of the waves rather than the conventional wave steepness. The beach is eroded (storm profile) when the nonlinear interaction of the waves is strong (storm wave), whereas the beach is accreted (swell profile) when the nonlinear interaction is weak (swell wave).

  • Among the fire incidents in Korea over the past decade, building fires are the most common, and property and human casualties are the most common. However, the existing fire fighting system does not only inform the location of emergency exits and guide safe routes to help casualties evacuate smoothly. A system was proposed to help successful evacuation by distinguishing vertical and horizontal characteristics using spatial characteristics. In this study, an effective evacuation system was proposed by predicting fires using temperature detection sensors and smoke sensor values, and calculating the optimal evacuation path through the Dijkstra algorithm.

  • Uses of geosynthetics as a reinforcing material for earth structures have ever increased due to their excellent economy. fine external appearance. and easy construction. In the current practice of geosynthetics. however, the lacks of the standardized method of evaluating the soil/geosynthetics friction properties and the inconsistency of conventional design methods develop confusion to the civil engineers. The purpose of site monitoring of the retaining wall reinforced by geogrids was to evaluate the applicability of existing design methods to, and performance of. CHAMSTONE wall system. Full scale field performance during and after construction was monitored by incorporating instrumentation including strain gauges on the geogrid and soil pressure cells. The difference of the reinforcing effects of geosynthetics embedded in the soil will be also investigated by comparing of the line and curve types of retaining wall reinforced by geogrids with block type facings.
