Lumbar interbody fusion (LIF) is an effective and popular surgical procedure for the management of various spinal pathologies, especially degenerative diseases. Currently, LIF can be performed with posterior, transforaminal, anterior, and lateral approaches by open surgery or minimally invasive surgery (MIS). Each technique has its own advantages and disadvantages. In general, posterior LIF is a well-established procedure with good fusion rates and low complication rates but is limited by the possibility of iatrogenic injury to the neural structures and paraspinal muscles. Transforaminal LIF is frequently performed using an MIS technique and has an advantage of reducing these iatrogenic injuries. Anterior LIF (ALIF) can restore the disk height and sagittal alignment but has inherent approach-related challenges such as visceral and vascular complications. Lateral LIF and oblique LIF are performed using an MIS technique and have shown postoperative outcomes similar to ALIF; however, these approaches carry a risk of injury to psoas, lumbar plexus, and vascular structures. Herein, we provide a detailed description of the surgical procedures of each LIF technique. We shall then consider the pearls and pitfalls, as well as propose surgical indications and contraindications based on the available evidence in the literatures.

<목적> 췌장의 장액성 낭종은 벌집모양의 소낭성종괴가 전형적이지만 최근 대낭성을 비롯한 다양한 형태의 낭종이 보고되고 있다. 이에 본 연구는 췌장의 장액성 낭종을 방사선학적, 육안적 특징에 따라 형태학적으로 분류하고, 각 유형의 특징을 파악함으로써 다른 췌장의 낭종과의 감별과 함께 향후 장액성 낭종의 치료지침을 수립하고자 한다. <방법> 1992 년 1월부터 2003년 8월까지 췌장 절제술을 시행받은 환자들 중 조직학적으로 장액성 낭종으로 진단된 32명

As the size of container ships continues to increase, not many existing harbors can host the super-container ship with its increased draft and the corresponding dredging requires huge budget. In addition, the minimization of waiting and offloading time is the most important factor in harbor competitiveness. In this regard, mobile-harbor concept has been developed in Korea to achieve much improved harbor capacity and efficiency. In developing the concept, one of the most important elements is the operability of crane between two or more large floating bodies in side-by-side arrangement. The container ship is to be stationed through a hawser connection to a fixed-pile station at a near-shore region with the depth allowing its large draft. The mobile harbors with cranes are berthed to the side of its hull for container loading/offloading and transportation. The relative motions between the two or more floating bodies with hawser connection have to be within allowable range for the effective crane operation. Therefore, the reliable prediction of the relative motions of the multiple floating bodies with hawser/mooring/fender is essential to find the best hull particulars, hawser/mooring arrangement, and docking-station design. Time-domain multi-hull-mooring coupled dynamic analysis program is used to assess the global performance of the moored system and the hydrodynamic interactions among the multiple floating bodies. In particular, the behaviors of the whole system in non-collinear wind-wave-current environment are simulated and compared to those of collinear cases.

In this paper, multi gap type ozonizer(MGO) has been designed and manufactured. The ozonizer is equipped with three electrodes(central electrode of screw shape, internal electrode and external electrode) of cylinder shape. This paper describes the following two characteristics: ① The characteristics of discharge with variation of output voltage of AC H.V source, flux of oxygen supplied gas and discharge voltage. ② The characteristics of ozone generation by varying flux and discharge power.
