  • 본 논문에서는 통계 어플리케이션을 웹 서버에서 내려받기 하여 클라이언트에 저장, 설치하고 stand alone 형태로 운영되도록 개발된 DAVIS에 대하여 개발 기법과 구현된 형태를 연구하고, 서버 기반의 통계 프로그램과 클라이언트 기반의 통계 프로그램에 대하여 고찰한다. 그리고 이들 유형에 대한 장단점을 파악하여 좀 더 발전된 통계학습시스템의 설계 방안을 제안한다. 이 시스템은 클라이언트 요청에 의하여 클라이언트에서 어플리케이션이 실행되고, 통계 데이터는 데이터베이스 서버에서 로드하거나 사용자에 의해 클라이언트에서 입력하는 형태로 설계되어 통계 분석을 수행토록 한다.

  • Soil nailing is a method of reinforcing natural deposits of soil with passive inclusions, called nails, of steel or other materials. Its purpose is mainly to increase the tensile and shear strength of the soil mass. This method has been widely used during the last two decades to stabilize steep slopes in several countries (France, Germany, USA, Japan, etc.). The design methods that have been mostly used are Davis method, German method, and French method which are based on limit equilibrium approaches, and Juran method which utilizes the kinematical limit equilibrium design concept. This paper is focussed on the evaluation of the available design methods(especially, the France, Davis and German design methods) through comparison with each different assumption for the failure surface, the concept of failure mechanism and the definition of safety factor. The parametric study to identify the effects of design parameters on the overall factor of safety has also been conducted. By considering the results along with the associated assumptions which have been postulated in the several methods, the applicability of the method for a given soil and nail conditions has been evaluated.

  • Milk is an important fluid in glycobiology because it contains a number of short carbohydrate chains either free or as glycoconjugates. These compounds as a class are the most abundant component and benefit the infant by developing and maintaining the infant's gut flora. New and emerging methods for oligosaccharide analysis have been developed to study milk. These methods allow for the rapid profiling of oligosaccharide mixtures with quantitation. With these tools, the role of oligosaccharide in milk is being understood. They further point to how oligosaccharide analysis can be performed, which until now has been very difficult and have lagged significantly those of other biopolymers.
