In the present study, an investigation has been made on the application of cement-bentonite soil mixtures as the countermeasure against leachate produced by buried animal carcasses. For this purpose, the strength characteristics of the cement-bentonite soil mixtures mixed with geotextile and metakaolin. After the mixtures with different contents of the cement (0 %, 10 %), bentonite (0 %, 5 %, 10 %, 15 %, 20 %), and weathered soil (100 %, 95 %, 90 %, 85 %, 80 %) were prepared, metakaolin and geotextile were added with different contents (metakaolin : 0 %, 5 %, 10 %, 15 %, 20 % of the cement weight; geotextile : 0 %, 0.5 %, 1 %, 1.5 %, 2 %). Experimental results suggested that the early strength of the mixture increases due to the pore filling, the hydration acceleration, and the pozzolan reaction when metakaolin of 5~10 % of the cement weight was added. In addition, the compressive strength increase when 0.5~1 % geotextile contents were added, and the above these contents, the rate of strength increase was gradually decreased because of the fibrous tangles.

In the previous C/S publishing system, the editor or contributor can arbitrarily modify the document created by the author, in which case it is difficult to identify the changes made in the document. Another shortcoming is in that when the document is in need of tracking or editing, the client must have the respective editing system. To solve this problem, the gist of the document must be preserved along with the document itself, and the process of handling the document must be standardized. Publishing on the web ensures a more stable and accurate result in processing documents. The significance of web publishing is made clear, when we consider the importance of information per se and the growing demand for immediate publication in the present day. The need for a simple and straightforward apache-based PDF publishing system, in which HTML and CSS are supported, and a converting engine provides PDF standard security application support, is prominent. This provides a library in which one can directly create a PDF via Windows, Linux, or Unix without having to rely on a client, allowing high-speed PDF creation. The development of a web-accessed PDF converting engine forms the basis for e-transactions, online brochures, electronic B/L, and many other industrial sectors.

본 논문에서는 실세계의 물체를 대상으로 학습 기법을 이용하여 3차원 입체의 형상을 명암 영상으로부터 복원하는 문제에 대해 새로운 접근 방법을 제시한다. 측광학 입체방법은 일반적으로 직접 조명을 기반으로 한다. 간접 확산 조명하에 있는 반사 특성은 Normal Sampler를 사용함으로써 결정할 수 있다. 그리고 한 객체의 3차원 형상은 pixel의 분포도로 회복할 수 있다. 본 논문에 있는 참조표는 객체의 3차원 형상을 회복하는데 이용된다. 제안한 방법을 혼성 반사에 의해서 정의될 수 있는 다양한 형태의 표면에 적용될 수 있다. In this paper, we present a new approach for determining the reflectance properties of surface and recovering 3-D shape from intensity image using learning method. Photometric Stereo Method is generally based on the direct illumination. Under the indirect diffuse illumination, the reflectance properties can be determined by using Normal Sampler and 3-D shape of an object can be recovered from intensity distribution of a pixel. In this paper, the reference table is used to recover 3-D shape of an object The proposed method can be applied to various to various types of surfaces which can be defined by hybird reflectance.
