The Emergency Department (ED) is an integral part of hospitals. Admissions from the ED account for a significant proportion for a hospital's activity. Ensuring a timely and efficient flow of patients through the ED is crucial for optimising patient care. In recent years, ED overcrowding and its impact on patient flow has become a major issue facing the health sector. Simulation is rapidly becoming a tool of choice when examining hospital systems due to its capacity to involve numerous factors and interactions that impact the system. An analytical simulation model is used to investigate potential impacts by changing the following aspects of ED (physical layouts; number of beds; number and rate of patient arrivals; acuity of illness or injury of patients; access to radiology and pathology services; hospital staffing arrangements; and access to inpatient beds). Results of a significant numerical investigation at a hospital are also presented.

Kimura disease is a rare idiopathic chronic inflammatory disorder. It typically presents in the head and neck area, whereas bilateral involvement is unusual. Its diagnosis requires it to be differentiated from other inflammatory diseases and from head and neck tumors. Treatment methods include conservative management, steroid administration, radiotherapy, and surgery; however, no single treatment of choice has been established. Herein, we report an unusual presentation of Kimura disease with bilateral parotid involvement. This case was treated by surgical excision.

Endoscopic sympathicotomy is the choice of the treatment for hyperhidrosis. There are some recognized risks such as Honer's syndrome and Hemopneumothorax; however, Chylothorax has very rarely been reported after thoracic sympathicotomy. We recently encountered a case of chylothorax. Early diagnosis and prompt treatment is noteworthy.

Choledochal cyst is a dilation that encloses the intrahepatic or both extra- and intrahepatic portions of the biliary ducts. Postnatally, ultrasonography is the initial diagnostic modality of choice, allowing for precise measurements of intra- or extrahepatic duct dilatation and identification of stones and sludge. Symptoms depend on the age at presentation. Common bile duct malformations should be considered as a differential diagnosis of a cystic mass regardless of the cyst's size or patient's age, especially in children presenting with abdominal pain, jaundice, and palpable mass. To the best of our knowledge, we report the largest choledochal cyst in infancy.

Histologically, Schmorl's nodes are defined as the loss of nuclear material through the cartilage plate, growth plate, and end plate into the vertebral body. Most Schmorl's nodes are asymptomatic, although there are some reports of symptomatic Schmorl's nodes, which should be treated similarly to vertebral compression fractures, with conservative treatment as the first choice. We report the case that we reduced the pain by blocking the ramus communicans nerve in a patient with Schmorl's node.

Epidermal cysts in mouth floor are rare. There could be confusions in diagnosis due to location and low incidence. For diagnosis, imaging study and cytology are necessary. The treatment of choice is complete excision intraorally or externally and the recurrence is rare. Some authors prefer sclerotherapy, but the follow up is necessary for malignant change. We report two cases of epidermoid cyst in submental area excised externally with literature review.

An enlarged spleen is considered one of the most common signs of malaria, and splenic rupture rarely occurs as an important life-threatening complication. Splenectomy has been recommended as the treatment of choice for hemodynamically unstable patients. However, a very limited number of splenic rupture patients have been treated with transcatheter coil embolization. Here we report a 38-year-old Korean vivax malaria patient with ruptured spleen who was treated successfully by embolization of the splenic artery. The present study showed that angiographic embolization of the splenic artery may be an appropriate option to avoid perioperative harmful effects of splenectomy in malaria patients.

This study is to confirm that SNS information characteristics have an effect on choosing hospital care and satisfaction on hospital. This study is conducted with a total of 301 respondents (150 of document investigation and 151 of mobile SNS research) from 16th January 2014 to 29th January. 168 respondents who have experience to collect SNS health information within 6 months recently was selected subject of analysis. In the results, we could confirm the followings. The reliability among SNS information characteristics has effect on convenience that is source of choosing hospital care. The reliability and agreement have effect on the professionalism among source of choosing hospital care. In the influence on having hospital satisfaction, the more reliable and agreeable, the more increasing of hospital satisfaction. In the influence between hospital choice element and hospital satisfaction, the more convenient and service available, the more increasing of hospital satisfaction. In conclusion, it is expecting to contribute SNS managers or marketer of medical institutions to taking out commitment on medical consumer's SNS.

소득수준 향상 및 인구특성 변화에 따라 증가하는 복합의료서비스 수요에 대응하여 본 연구는 의료복합시설을 부동산개발을 위한 독립적인 대상으로 고려하여 의료복합시설 개발을 위한 시설용도별 이용자 선택기준에 대한 분석을 실시하였다. 이를 위해 개발수요분석을 위한 기초자료로서 시설선택기준을 정의하고 AHP분석을 통해 중요도와 우선순위를 도출하였다. 의료복합시설을 구성하는 '의료관련시설', '지원시설', '보건 및 편의시설' 및 '기타시설'의 네 가지 시설용도에 따라 중요도를 비교 분석한 결과, '시설의 수준', '이용가격', '이용 편리성', '병원의 수준', '서비스', '인접성', '교통의 편리성' 등의 기준들이 서로 다른 차이를 보여 복합 시설 용도 별 이용객의 선택속성에 대한 시사점을 제공하였다. 연구결과를 통해 향후 의료복합시설 개발 시 타당성 분석 및 평가를 위한 기초적인 자료를 마련하고 용도 간의 최적의 조합을 통한 시설구성 대안을 도출하여 효율적인 개발을 위한 자료로 활용되고자 한다.

이 연구는 최근 개발된 컴퓨터를 이용한 정신운동 기능 검사법인 Neurobehavioral Tests fur Occupational Screening(NTOS)의 타당도 평가를 위해 시도되었다. 일개 종합병원 신경과에 등록된 파킨슨병 환자 12명과 신경독성물질에 폭로된 적이 없는 근로자 21명을 대상으로 NTOS의 단순반응시간 검사, 2가지 선택반응시간 검사, 양 손의 수지타진검사를 실시하였다. 평균 단순반응시간은 근로자군은 245 msec, 환자군은 378 msec였으며, 2가지 선택반응시간은 근로자군은 444 msec, 환자군은 671 msec 로 나타나 T 검정에서 유의한 차이를 보였다. 주로 쓰는 손의 수지타진검사는 68.6회를 나타내었고, 파킨슨병 환자군은 51.6회, 주로 쓰지 않는 손은 각각 60.9회, 43.1회로 유의한 차이를 보였다. 환자군과 근로자군의 연령과 학력차이를 통계적으로 보정하고 두군에서 차이가 나는지를 알아보기 위해 공분산분석을 실시한 결과, 단순반응시간, 선택반응시간, 수지타진이 유의한 결과를 보였다. 이상으로 볼 때, NTOS는 정신운동기능의 장애를 발견할 수 있는 도구라고 생각된다. 그러나 선택반응 시간 검사의 실수 횟수 같이 상대적으로 민감하지 못한 지표에 대한 고려가 필요하며, 혼란변수를 연구 설계에서 조정할 수 있는 큰 규모의 연구와 정신운동기능의 잠재적 장애를 보이는 집단에 대한 연구들이 추후에 있어야 할 것이다.
