A vertebral arte [VA] injury presents a difficult problem in atlantoaxial fixation. Recent technical reports described posterior C2 fixation using bilateral, crossing C2 laminar screws. The translaminar screw technique has the advantages of producing little risk of VA injury and the unconstrained screw placement. In addition, biomechanical studies have demonstrated the potential of the translaminar screw technique to provide a firmer construct that is equivalent to methods currently used. We report the successful treatment of C1-2 instability with a left-side high-riding VA. Because of the potential risk of VA injury, we performed a posterior C1-2 fixation with a combination of pedicle screws and a laminar screw in C2. We first placed bilateral C1 lateral mass screws and a right-side C2 pedicle screw. However, placement of the left- side C2 pedicle screw was technically difficult due to a narrow isthmus and pedicle. A laminar screw was inserted instead and authors believe that this posterior C1-C2 fixation with a combination of pedicle screws and a laminar screw in C2 can be a useful alternative technique for the treatment of C1-C2 instability in the presence of a unilateral high-riding VA.

Food waste is an inverse measure of consumer acceptability of the food as served and hence a potential determinant of food qualify. The plate waste of patients was examined by a visual method at one hospital. Patients were asked to record after each item on their menu the amount consumed in quantitative terms: None, 1/4, l/2, 3/4, all. The survey showed that 65% of all patients surveyed left some of their food during hospitalization. Mean wastes for soups and meat side dishes were found to be larger than those for cooked meals and vegatable side dishes. At the same time, a questionnaire survey was used to determine the view of patients of key aspects of the hospital foodservice system. The majority of patients surveyed left their cooked meal because of low appetite, whereas patients indicated that Food is not tasty was the primary reason for leaving soups and other side dishes.'Satisfaction' scores were significantly correlated with the patients' age and appetite at the time.

본 논문에서는 1채널(mono)이나 2채널(stereo)의 오디오 입력을 5채널(center, left, right, left side, right side)로 출력시키는 음장 시스템을 설계하고 그 성능을 분석하였다. 가정의 리스닝 룸 같이 작은 공간에서 콘서트 홀 같은 커다란 공간의 음장을 재현하기 위한 멀티 채널 음장 시스템은 지연기, 초기 반사음처리기, 잔향기를 이용해 설계하였다. 초기 반사음 처리기의 지연과 이득은 실제 공간에서 측정한 암펄스 응답을 이용하여 결정하였으며, 구현된 초기 반사음을 전방 30$^{\circ}$방향에서 재생함으로써 확장감을 증가시킬 수 있도록 하였다. 잔향기는 자연스러운 주파수 및 감쇠 특성을 갖도록 설계되었으며, 후방 60$^{\circ}$방향에서 재생되는 잔향의 상관 계수를 작게 함으로써 청취시 공간감을 느끼게 하였다. 설계된 음장 시스템은 무향실 데이터를 입력으로 시뮬레이션되었고, 그 결과로 얻어진 5개의 PCM 출력은 멀티 트랙 재생 장치에 의해 일반 리스닝 룸에서 재생된다.

Congenital coronary fistula is a rare condition, and with widespread use of cardiac catheterization, angiography and selective coronary arteriography are being recognized with increasing frequency. Fistula originating from the right coronary artery are more common than those from the left coronary artery. The fistula empties into the right side of the heart in 90% of the cases with the right ventricle being the most common recipient chamber, followed by the right atrium and the pulmonary artery. We report a case of congenital coronary artery fistula of the right coronary artery to the left ventricle with significant shunt in a 20 - year old female. It was detected by transthoracic and transesophageal echocardiography and confirmed by cardiac catheterization and coronary angiography. The fistula opening was closed with 6-0 Prolene continuously under cardiopulmonary bypass and moderate hypothermia [ 28 oC ]. Postoperative course was uneventful and the patient was discharged without specific problem.

Facial nerve schwannomas are uncommon tumors. A 40-year-old female presented with left-side facial weakness. Computed tomography[CT] imaging showed a $3\;{\times}\;2cm$ lesion on the posterior portion of the left middle cranial fossa. The mass abutted the anterior aspect of the left petrous bone with a wide erosive change involving the area of the left facial nerve ganglion [geniculate ganglion]. A well-circumscribed extra-axial mass was seen on magnetic resonance imaging[MRI]. The tumor was completely removed through subtemporal approach and the patient was discharged without additional neurological deficit. This rare case is discussed and a review of the relevant literature is presented.

It is widely known that sciatic nerve injury (SNI) can negatively affect the biomechanical characteristics of the musculoskeletal system. However, there were no studies that evaluated and compared denervated side with another side limb at the same time. In this study, sixteen male 12-week-old mice were allocated into two groups: HEMI (Right Sciatic nerve denervated) and CON (Control). Both limbs were scanned using micro-CT at 0 week and 4 weeks. There were significant differences in relative variation (RV) of BMD and all structural parameters compared CON and HEMI in right tibia (p < 0.05). Tb.Th and Tb.Sp distributions were differed CON with HEMI in right tibia. In left tibia, there were significant differences in RV of BMD (p < 0.05) and Tb.Sp distribution. These result means that SNI can induce bone loss in the both side tibiae. However, there was a different profile of bone loss between left and right tibiae.

Shoulder Hand Syndrome is used to describe painful disabilities of the upper extremity due to disturbances of sympathetic nerve supply. A 72 year old male developed hemiplegia on left side on the 5 days after open heart surgery of aortic valve replacement. Three months later, the patient complained of severe pain in the left upper extremity involving shoulder. The left hand showed swelling and flaccid paralysis. Thereafter the left stellate garglion block with 10 ml of l% lidocaine produced prompt pain relief. Thereafter the patient received 94 stellate ganglion block during 7 months which produced permanent remission of pain throughout a 1 year follow period. We recommand sympathetic block for of Shoulder Hand Syndrome following hemiplegia.

Authors have obserbed a rare case of unilateral hypertrophy occured in the left mandibular condyle of 25 years old man. In the serial roentenograms, Authors have drawn following conclusions. 1. The patients face is markedly asymmetrical. This asymmetry consisted of an elongation and widening of the left mandibular ramus, neck and head of condyle which pushed the chin to the other side. 2. Left mandibular angle is flattened and mandibular inferior border is lower than right. 3. In the relationship of the left posterior teeth, severe mesioocclusion is occured.

There are takes performed on only one side (right side or left side) of the assembly line, and task groups in which the tasks are more related to one another like a subassembly. In the Assembly Line Balancing (ALB) of the large-sized product such as bus and truck, the side on which tasks are performed and the related task groups should be considered to improve work methods and to appropriately lay out parts and facilities in the line. In this paper, presented are the 0-1 programming formulations for the ALB with the constraints of assigning the same side tasks to the station. The objective of minimizing the number of stations is combined with the objective that the total number of the related task groups handled by all the stations is minimized. Also, proposed are the methods of reducing the number of variables and constraints, and of determining the station to which subassembly tasks are assigned.
