We report a case of aberrant cervical thymus in the left submandibular area of a three-month-old boy. On US scan and MR images, a well-marginated, 4 cm-sized solid mass along the left carotid sheath, anteromedial to the sternocleidomastoidmuscle and inferior to the submandibular gland, was seen. MR signal intensity of the mass showed that it was similar to that of normal thymus in the anterior mediastinum. Although a rare disease, ectopic thymus should be included in the differential diagnosis of cervical masses along the carotid sheath in infants.

C0-continuous isoparametric Timoshenko beam element for rotating

김용우,Jaeho Jeong 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.5

This paper presents a C0-continuous isoparametric finite element for free vibration analysis of a rotating, tapered Timoshenko beam mounted on the periphery of a rotating rigid hub, at a setting angle with the plane of rotation. The finite element has three nodes and two degrees of freedom per node and employs modified shape functions for rotational displacement associated with the shear strain energy to avoid shear locking. To obtain a finite element equation of the generalized eigenvalue problem, Hamilton's principle is applied to kinetic and potential energy expressions of a rotating Timoshenko beam with non-zero setting angle. The numerical solutions for various situations including variations of rotational speed, taper ratio, slenderness ratio, hub radius and setting angle are compared with other numerical results available in the literature whenever possible. The results show that the new 3-noded isoparametric element yields accurate results when compared to other numerical ones.

Vallecular cyst is a rare in children. Vallecular cyst consists of a unilocular cystic mass of variable size arising from the lingual surface of the epiglottis and containing clear, non-infected fluid. Vallecular cyst has been reported in the literature under different names and this has led to some confusion. Terms used have included mucous retention cyst, epiglottic cyst, base-of-the-tongue cyst, congenital cyst and more recently ductal cyst. This later name originates from the classification of DeSanto et al, in which they grouped laryngeal cysts according to their location and surface mucosa (Thyroid cartilage foraminal cysts ; Saccular cysts ; Ductal cysts). This classification has become popular but has the limitation that, it was largely based on observation in adults and did not recognize different anatomical sites and variations in clinical presentation. Although these cysts are benign, they may cause serious airway obstruction and even death if not treated appropriately. A mortality rate of about 40% in children with laryngeal cysts was reported1. Vallecular cyst or pre-epiglottic cyst is a rare but recognized cause of respiratory distress in infancy or immediately after birth. It has been associated with sudden airway obstruction resulting in death. We experienced two cases of vallecular cyst with feeding difficulty and stridor in 2-month old female and dyspnea in 4-month old male who symptom relief by endoscopic laser-assisted resection. With a review of literature, authors report two cases of vallecular cyst with the symptoms of upper airway compromise.

Intrapelvic Migration of the Lag Screw with Wedge Wing from Dyna Locking Trochanteric Nail: A Case Report and Literature Review

김용우,김원유,김경준,이세원 대한고관절학회 2019 Hip and Pelvis Vol.31 No.2

The intrapelvic migration of cervicocephalic lag screws is a rare complication after intertrochanteric fracture synthesis with an intramedullary nail. Only 15 cases of intrapelvic penetration by three different instrument systems have been described in the literature. However, to our knowledge, there is no report of intrapelvic migration of the lag screw with wedge wing designed to increase fixation power using the Dyna locking trochanteric (DLT) nail. We present a case of intrapelvic migration of the lag screw with wedge wing from DLT nail. The patient described herein underwent a two-staged operation of implant removal without intrapelvic approach followed by bipolar hemiarthroplasty. With intrapelvic migration conditions, although it is not uncommon to require an additional intrapelvic approach, this modification can lead to lethal consequences. For this reason, it is recommended to coordinate with the vascular surgery department due to the close proximity of the major vessels.

혐오와 급성음주가 도덕판단에 미치는 영향

김용우,권영실,현명호 한국청소년학회 2018 청소년학연구 Vol.25 No.2

This study aims to elucidate the effect of disgust and acute alcohol consumption on moral judgment. To do so, amongst healthy social drinkers without history of drinking related problems, 60 under- and postgraduate male students were selected. They were randomly and evenly assigned into 4 groups which are distinguished by absence or presence of alcohol and the disgusting or neutral nature of the visual treatment to perform moral judgment tasks. Experiments in each group were performed once in 90 minutes, and in order to control the rapidity and extent of alcohol metabolism, drinking, eating and taking medications were forbidden prior to the experiment. The results are that those who were treated with disgusting visuals made strict moral judgments whereas those who drank made lenient ones. Post hoc showed that the group that was treated with both disgusting visuals and alcohol also made lenient moral judgment. This can be interpreted as drinking reducing the effect of disgusting feeling on driving harsh moral judgment. This study provides insight into the cause of lenient moral judgments that appear during acute alcohol consumption. Finally, the restrictions and the direction for the further study are provided. 본 연구는 혐오와 급성음주가 도덕판단에 미치는 영향을 확인하는데 목적이 있다. 이를 검증하기 위해 건강한 사회적 음주자 남자 대학생 및 대학원생 60명을 선발하였다. 이들을 각각 알코올(유 / 무) × 영상 처치(혐오 / 중립)에 따라 각각 15명씩 4집단으로 무선배정하여 도덕판단 과제를 실시하였다. 각 집단에서의 실험은 1회 90분이었고, 알코올이 체내에 확산되는 속도와 정도를 통제하기 위해 음주와 식사, 약물섭취를 사전에 제한하였다. 연구결과 혐오영상 처치를 받은 집단은 엄격한 도덕판단을 내렸고, 음주처치를 받은 집단은 엄격하지 못한 도덕판단을 내렸다. 또한 혐오영상과 음주의 상호작용효과가 발견되어 혐오영상을 보았더라도 음주처치를 받은 집단의 도덕판단이 엄격하지 못한 것으로 나타났다. 이는 음주가 도덕판단을 엄격하게 만드는 혐오감의 효과를 억제시켰다고 해석할 수 있다. 본 연구결과는 급성음주 상태에서 나타나는 엄격하지 못한 도덕판단의 원인에 대한 시사점을 제공한다. 마지막으로 본 연구의 제한점 및 추후 연구에 대한 방향을 제시하였다.

병원경영전략으로서의 H.I.P에 대한 연구

Today, the quality of medical care is generally in an upward equalization with the introduction of state-of-the-art medical equipment and with the scale of hospitals becoming bigger, so hospital image stands out as an important differentiating factor among hospitals. Hence, this study focuses on H. 1. P(Hospital Identity Program) from a management strategy aspect. H. 1. P. constitutes a hospital's visual uniformity for the pursuit of differentiation from other hospitals and further acts as an important factor in management rationalization and can be separated into the following three factors: 1) V. I. to unify logo, character, and corporate color, etc. visually 2) M. I. to unify the consciousness of organization's members 3) B. I. to unify their bihavior From the aspect of the above three factors, the function of H. I. P., the subject differentiating it from other hospitals in order to arrive at a hospital's rational management, performance, makes the ideal image showing the hospital's management philosophy and goal intensively. In addition, it is an active and voluntary self-conviction communication method to make hospital personnel, present and potential customers recognize these ideal images uniformly. Therefore in this study, H. I. P. of EUL JI Medical Center was produced actually.
