The etiology of thrombosis is multifactorial and involves the interaction of inherited and acquired risk factors. Many neonatal thromboembolic disorders are iatrogenic and their incidence is likely to increase as advancements are made in neonatal care. Among pediatric populations, neonates have the highest risk for thrombosis secondary to the unique developmental hemostatic system, inherited prothrombotic disorders, and perinatal clinical conditions. Central venous and arterial catheters present the greatest risk for developing thromboembolisms in neonates. Both venous and arterial thromboses have been reported in a variety of anatomic locations. Prompt identification and appropriate management of thromboembolisms is critical for avoiding life-threatening complications. To date, few data are currently available regarding the contribution of inherited and acquired prothrombotic disorders in the pathogenesis of neonatal thromboembolism. In particular, a lack of information about neonatal thromboembolism in Korea has inhibited the development of appropriate guidelines for diagnosing thromboembolisms in neonates. An overview of the current knowledge about the role of inherited and acquired risk factors for neonatal thromboembolism in the West and a detailed description of common neonatal thromboembolic diseases is reviewed.

Unresolved major pulmonary embolism (UMPE) is an uncommon condition which causes pulmonary hypertension, cor pulmonale and death. An accurate and prompt diagnosis of UMPE is very important in the management of such patients with pulmonary embolectomy. Follow-up lung scans can lead to earlier diagnosis of UMPE especially on patients who have a history of acute pulmonary embolism in the past and. present with pulmonary hypertension, respiratory insufficiency and cor pulmonale. We report a case of UMPE strongly suggested by follow-up lung scans and subsequently confirmed by pulmonary angiography and postmortem examination.

Acute patellar dislocation is a painful, terrifying experience that always occurs suddenly. The recurrence is unfortunately common and each experience is just as painful to the patient. With each acute dislocation, additional intraarticular derangement occurs. Therefore the goals of treatments are not only to relieve acute pain by prompt reduction of the dislocation but also to remove any chondral or osteochondral fragments that may be present within the knee joint and to restore normal patellofemoral anatomy, thereby preventing recurrent dislocation and avoiding future patellar subluxation. To present the details of arthroscopic medial retinacular repair in acute patellar dislocation. we report 2 patients with treatment of acute patellar dislocation with osteochondral loose body.

Good stability and complete range of motion should be the ultimate goal of a rehabilitation program after ACL reconstruction. In previous years. the rehabilitation of the ACL reconstructed knee focused on protecting the new ligament by blocking terminal knee extension, hut, despite good stability, this approach led to numerous postoperative complications. Nowadays, most of surgeons agree the accelerated rehabilitation program based on the concept of ligamentization and clinical experience. Accelerated rehabilitation program consists of maintain of full extension of the knee, early weight bearing and prompt recovery of ROM, and closed kinetic chain exercise. Meeting this goal requires effective communication between-members of the health care team-the physician, physical therapist, atheletic trainer, and the patient. We have to know the importance of rehabilitation, knowlege about the physical therapy, and to introduce for special physical therapist and equipment.

This paper proposes a mechanism for prompt and efficient construction of sensor network connecting sensor nodes and base stations using limited length edges minimum spanning tree. This mechanism can rapidly build a connecting tree which may be used in routing of sensor network. In an experiment for 2000 input terminal nodes, this mechanism can curtail 94.7% construction time comparing with the method by naive minimum spanning tree without tree length overheads. This shows the proposed mechanism can apply well to the application of swift construction of a sensor network.

Due to the rapid increase In the Internet traffic volume, ISPs are faced with the definite need of the expansion of server capacity. In order to Provide prompt services for customers and still prevent excessive facility cost, it is critical to determine the optimum level of internet server capacity. The purpose of this Paper is to provide a simple but effective strategy on the expansion of servers capacity according to the increase in internet traffic. We model an internet server as an M/G/m/m queueing system and derive an efficient method to compute the loss probability which, In turn, Is used as a basis to determine proper server capacity. The Process of estimating the traffic parameter values at each server based on log data analysis is also given. All the procedures are numerically demonstrated through the process of analyzing actual log data collected from a game company.

The authors report a case of Currarino triad which had a congenital anorectal stenosis associated with a sacral defect and a presacral mass. A 1-year-old female presented with constipation since birth. Neurological deficits were not found on admission. She had had a diverting colostomy due to anorectal stenosis at another hospital before admission. Lumbar X-ray films showed bony defect caudal to the third sacral vertebra. Magnetic resonance image demonstrated a round cystic pelvic mass which was connected with a dural sac via anterior sacral defect. Posterior approach with Intradural removal of the presacral cystic mass was performed and followed by anoplasty by a pediatric surgeon. The cystic mass was verified histologically as mature teratoma with cystic change. Postoperatively, the urinary function and bowel movement remained intact. Currarino triad should be suspected and evaluated physically and radiographically in a case of congenital anorectal stenosis. Prompt recognition and close cooperation between pediatric surgeons and neurosurgeons is advisable to ensure adequate surgical treatment.

Tracheoinnominate artery fistula is a critical complication of tracheostomy. The most important factors influencing patient outcome are prompt diagnosis, immediate control of bleeding with a patent airway, and emergency operation with or without interruption of the innominate artery. Here, we report a case of tracheoinnominate artery fistula in a 40-year-old woman with cerebrovascular accident who was successfully managed with an aorta-axillary artery bypass.

The architectural design requires collaboration among various participants, such as architects, clients and engineers in the stages of the design process. Rapid development of information technology enables effective and prompt exchange and sharing of digital architectural information, otherwise should have been exchanged and managed by traditional ways. However, the core technology for supporting this demands has not been fully investigated so far. This paper aims to show the possibility of adopting network based architectural design information sharing system through surveying and analyzing the state-of-the-art network technology and its uses in architectural information exchange among various design actors. To realize these aims, this paper 1) investigates and analyzes the current status of network technology in the architectural and construction practice, 2) suggests systematic information exchange and sharing mechanism for architectural products and drawings data, and 3) demonstrates network based prototypical architectural information system.

Presented here is a 36-year-old male with arterial hypertension who developed brainstem edema and intracranial hemorrhage. Magnetic resonance scan revealed diffuse brainstem hyperintensity in T2-weighted and fluid-attenuated inversion-recovery images, with an increase in apparent diffusion coefficient values. After a reduction in blood pressure, rapid resolution of the brainstem edema was observed on follow-up. The patient's condition was thus interpreted as hypertensive brainstem encephalopathy. While many consider this a vasogenic phenomenon, induced by sudden, severe hypertension, the precise mechanism remains unclear. Prompt recognition and aggressive antihypertensive treatment in such patients are essential to prevent permanent or life-threatening neurologic injury.
