국내의 기계 및 설비관련 학과는 모든 산업의 기초가 되는 기계를 다루는 기술인이 반드시 알아야 할 기계관련 이론과 다양한 실기를 통해 산업현장에 필요한 전문직업인 양성에 교육 목표를 두고 있다. 또한 오늘날 첨단 기계 산업의 발달 및 다양화에 따라 생산 및 생산시설 관리, 제품 설계 및 제작, 엔지니어링 마케팅, 컴퓨터 하드웨어 및 소프트웨어 관련 업무를 충실히 담당할 중견 전문가 양성도 담당하고 있다. 기계 설비분야의 미래를 책임질 기계설비 전문인을 양성하기 위해 기계 및 설비관련 학과는 2009년 현재 전국의 13개 대학에서 다양한 커리큘럼을 통해 배출하고 있다. 본지는 지난 3월호부터 전국의 기계 및 설비관련 학과를 소개한다.

To calculate the end bearing capacity of a drilled Shaft socketed into the rockmass, the unconfined compression strength could be used. But it is difficult to find the unconfined compression strength because it is impossible to get undisturbed samples in weathered soils and rocks. So, to calculate the end bearing capacity, the existing bearing formula could not be used. In this study, for five zones (near pile tip, tip~lower 1D, tip~lower 2D, upper 1D~lower 1D, upper 1D~lower 2D), the relationships between the characteristic values of in-situ tests(SPT, DCPT PMT, BST) and the end bearing capacity of drilled shafts were analysed. As a result, DCPT results were represented the best credibility. Also, a design chart of end bearing capacity using DCPT was suggested.

Todo was an uninhabited island located in the sea of Pusan Newport. It was a small island with the height of 32 m above sea level, and its area including the submerged part was approximately 24,400 ㎡. Unfortunately, the island was located exactly in the middle of the narrow entrance way to the North and South Container Wharfs of Pusan Newport so that a number of ships had to turn quickly to avoid collision with the island, which frequently caused collisions with other ships or cranes. To avoid such a danger and make the water way wider and deeper, the Ministry of Oceans and Fisheries decided to remove the island. This was believed to make even super-large vessels operate safely in the sea of Pusan Newport so that the competitiveness of the port could be highly enhanced. This paper describes in detail the whole process of the removing work, which was the first case of successful underwater blasting operation using bulk emulsion explosives and non-electric detonators to remove a whole island in South Korea.
