Helidecks are used to access offshore installations for support and transport operations. The helideck and its supporting structure are critical safety elements due to their essential role in emergency evacuations. Therefore, the design of helideck structures should satisfy operational and accidental conditions. In current industrial practice, aluminium pancake designs tend to be based on a steel section profile with modifications. The design of aluminium helidecks should consider evaluations of

최근 국내에서 경영대학의 MBA(Master of Business Administration) 학위에 대한 관심이 증대되고 있다. 우리나라 기업 고위직의 55% 이상이 이공계 출신이고 기업에서는 이들이 경영학적인 지식을 갖고 있길 원한다는 사회적 현상에 의해 이공계 학생들이 경영학을 배울 필요성을 느끼고 있는 것이 현실이다. 복수학위제도는 이러한 학생들의 요구사항을 만족시킬 수 있는 제도의 하나이다. 복수학위를 취득하고자 하는 학생은 특정 분야를 전공하면서 동시에 MBA를 전공함으로써 시간 및 비용을 절감할 수 있는 효과가 있어서 미국의 경우 매우 많은 대학이 MS(Master of Science)/MBA 복수학위 과정을 비롯하여 MBA와 다른 학위와의 복수학위 과정을 제공하고 있다. 아직 국내에는 MBA와 타 학위를 동시에 취득할 수 있는 복수학위 과정이 정착되어 있지 않다. 본 논문에서는 이과/공과대학으로 대표될 수 있는 MS(Master of Science) 학위와 MBA 학위

Helicopters are essential for supporting offshore oil and gas activities around the world. To ensure accessibility for helicopters, helideck structures must satisfy the safety requirements associated with various environmental and accidental loads. Recently, offshore helideck structures have used aluminium because of its light weight, low maintenance requirements, cost effectiveness and easy installation. However, section designs of aluminum pancakes tend to modify and/or change from the steel p

Ships and offshore structures are exposed to various types of extreme and accidental events including fire, explosion, collision, dropped objects, etc. These events lead to nonlinear structural consequences. This paper focused on grated-steel deck structures subjected to dropped-objects. The aim of this paper is to confirm the nonlinear impact response of grated-steel deck structures. An experimental study was undertaken in a dropped object test facility and LS-DYNA nonlinear finite element comp

Malignant external otitis is a potentially life-threatening infection of the external auditory canal and skull base, typically seen in elderly diabetic or immunocompromised patients. Pseudomonas aeruginosa is the bacteria most commonly responsible for the infection. The disease process begins as an external otitis that may progress into an osteomyelitis of the skull base. Cranial nerve palsies may occur as the disease progresses, and in some cases, sigmoid sinus thrombosis and meningitis have re
