  • 최근 음운론에서 lateral 자질이 자질수형도에서 어디에 위치하는가에 대해 두 가지 접근이 있어 왔다. Levin(1988)은 lateral이 coronal에만 나타나는 제약에 기초해서, lateral 자질이 coronal 마디의 의존자질이라고 주장한다. 이에 반해 Rice & Avery(1991), 그리고 Shaw(1991)는 lateral 자질이 자질수형도의 위쪽에 위치한다고 주장한다. 이 두 이론을 비교하기 위해 본 논문에서는 다음과 같은 내용의 음운론적인 요소들과 음성학적인 요소들을 고려한다. 첫째, 음성학에서 lateral의 기능은 lateral이 일반적으로 수형도 위쪽에 위치하는 것으로 간주되는 조음방법 자질이라는 것을 시사한다. 둘째, Papuan 언어군에서 보고된 Velar lateral의 존재는 lateral이 coronal에만 나타난다는 제약을 무효화하면서 Levin이론의 전제를 의심스럽게 한다. 셋째, 몇 가지 다른 유형의 동화 현상에 대한 논의는 동화현상이 lateral이 수형도의 위쪽에 위치하는 이론에서 더 잘 설명된다는 것을 보여 준다. 마지막으로 Chumash와 Tahltan의 coronal harmony에서 나타나는 lateral의 transparency와 Cambodian과 Javanese에서 나타나는 OCP효과 따위도 lateral이 조음위치 마디의 의존 자질인 이론에서는 설명될 수 없는 underspecified lateral의 증거를 제시한다. 이와 같은 논의에 기초해서 본 논문의 결과는 lateral이 수형도 위쪽에 위치한다는 주장이 옳음을 보여준다.

  • The electrical activities of masseter muscle were recorded on 9 subjects with unilateral fracture of mandible. The electromyographic studies were executed with 2 channel RS dynograph recorder for electromyography. The graphs were recorded in the physiologic rest position, incisal occlusion, molar occlusion, left lateral excursion, right lateral excursion, and protraction. The following conclusions were drawn; 1. In the physiologic rest position, incisal occlusion, molar occlusion, and protraction, the electrical potentials of the masseter muscle were greater in the affected side. 2. In the right lateral excursion, the electrical potentials of the masseter muscle were greater in the right side, and in the left lateral excursion, greather in the left side. There is no correlation mutually between the affected side and unaffected side.

  • The purpose of this study is to know the value of the photographic subtraction technic in the transcranial oblique lateral projection of the TMJ. The author examined the transcranial oblique lateral projection radiographs which comprise 50 cases of 32 persons, compared the transcranial oblique lateral projection films and those subtraction films. The following results were obtained. 1) The condyle at closed jaw position had showed a reversed tone image, but the condyle at the opening position had showed a re-reversed ordinary image. Both condyles had showed one subtraction film because radiographic interpretation of TMJ was easy. 2) On 50 cases of subtraction films, 46 cases had showed same radiographic images compared with trascranial oblique lateral projection films. Four cases (3 cases of erosion, 1 cases of sclerosis) had showed additional changes of images so that capability of interpretation was improved.

  • In the framework of linear representation which allows for no internal structure within features, there is no way to represent nonlinear phonological phenomena such as complex segments. This paper shows how we carl solve some problems of the linear feature theory in relation to the hierarchical feature theory. The purpose of this paper is to explain lateral assimilation under hierarchical feature representation. Although arguments for the position of classes of distinctive features have been made the position of (lateral) remains the issue of debate. Sagey(1988) argues that the feature [lateral] is structurally dependent on the root node. In contrast Rice & Avery (1991) put the feature (lated) under the spontaneous voicing. I have discussed previous studies of feature hierarchy and I propose a revised model of feature representation. Within this model I have shown how well feature geometry describes lateralization as feature spreading.

  • The upshoot and downshoot in Duane's retraction syndrome is believed to be related to a leash effect from the lateral rectus muscle. When the eye is rotated into the adducted position, the lateral rectus muscle slips over the globe, producing the up-and downshoot on adduction. The splitting of the ends of the lateral rectus into a Y configuration prevents the rotation of the globe up or down by stabilizing the muscle's position on the eye. Three patients with Duane's retraction syndrome demonstrated abnormal vertical movement on adduction and underwent a Y-splitting on the lateral rectus. In all patients, marked decrease in the up-and downshoot is noted after surgery.

  • Objectives : This study investigated the relationship between straight leg raising(SLR), valsalva test and size, position of lumbar disc herniation. Methods : We took SLR and valsalva test on 105 patients with lumbar disc herniation. According to the result of MRI findings, this study classified three groups of 105 patients with lumbar disc herniation, bulging, protrusion and extrusion. According to the position of lumbar disc herniation, 72 patients that were diagnosed protrusion and extrsuion were sorted 4 groups, lateral, lateral postero-lateral, central postero-lateral, central. The association size, position of lumbar disc herniation and SLR, valsalva test were analysed. Results : The bigger size of disc herniation, the more positive result of SLR and valsalva test, the lower angle of SLR test. There was not significant association between the position of lumbar disc herniation and the angle of SLR test. Conclusions : The SLR and valsalva test is an useful physical examination to speculate about the degree of lumbar disc herniation.

  • Generally uniform dose distribution is assumed to be formed in a target region when a conventional dose formation method using a broad proton beam, a fixed modulation technique, a bolus and an aperture is employed. However, actual situations differ. We usually find non-uniformity in the target region. This is due to the insertion of a range-compensating bolus before the patient. Since the range-compensating bolus has an irregular shape, the scattering in the bolus depends on the lateral position. Dose distribution is overlapping results of dose distribution of pencil-proton beams traversing different lateral positions of the bolus. The lateral extent of dose distribution of each pencil beam traversing the different position differs each other at the same depth in the target object. This is a cause of the non-uniformity of the dose distribution. Therefore the same lateral extent of dose distribution should be attained for different pencil beams at the same depth to obtain a uniform dose distribution. For that purpose, we propose here a bi-material bolus. The bi-material bolus consists of a low-Z material determining mainly the range loss and a high-Z material defining mainly the scattering in the bolus. After passing through the bi-material bolus, protons traversing different lateral positions will have different residual range yet with the same lateral spread at a certain depth. Using the optimized bi-material bolus, we can obtain a more uniform dose distribution in the target region as expected.

  • This report evaluated the convenience and accessibility of a penile translocation surgery in the lateral recumbency of a calf using a tilt-up mobile compared with that of dorsal recumbency on the ground of a barn. One nine-month-old F-1 (Korean native sire x Holstein dam) calf was sedated with xylazine (0.03 mg/kg, IV) and restrained in the right lateral recumbency position on a tilt-up restraint mobile (90 cm high), whereas the other nine-month-old Korean native calf was administered xylazine (0.3 mg/kg, IV) and restrained in dorsal recumbency position on the ground of a barn, with assistance by one person. For the two calves, lidocaine was administered subcutaneously from the preputial orifice to the S-shaped penis. The preputial orifice was incised, and the preputial sheath and penis were separated bluntly, then laterally translocated to the site toward the left flank at a $40^{\circ}$ angle. Anti-inflammatory drug (ketoprofen) and antibiotics (penicillin) were administered following the surgery. The duration of surgery was 30 min shorter in the calf that received the surgery in lateral recumbency using the tilt-up mobile with operator's standing posture (60 min) than the one that underwent surgery in dorsal recumbency on the ground with operator's bending posture (90 min). One week after the surgery, the operation area, including the translocated preputial orifice, was healed without complications in both cases. The results detailed in this report demonstrate that penile translocation surgery in the lateral recumbency position using a tilt-up mobile might be used conveniently in calves due to the convenience of restraint, reduced surgery time, and reduced physical inconvenience for the surgeon.

  • The vibratory gyroscope can effectively measure the angular velocity as the oscillating and position-sensing mode are exactly tuned. The veering Phenomenon impedes the exact tuning, which is caused by the mode coupling of two modes. In this paper, the gyroscope's structure with two frames is introduced to minimize the veering phenomenon that destabilizes the tuning process of oscillating and position-sensing mode. Experimental results show that the Proposed structure can achieve the mode intersection without veering phenomenon.
