Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.

빠르게 변하는 정보화 사회에서 방대한 양의 문서 정보를 전자 문서로 만들고 관리하는 것은 필수적이다. 이러한 전자 문서를 표현하는 데 있어서 사용하는 문서 내에 포함된 모든 정보를 손실 없이 저장하고 관리하는데 적합한 언어가 전자 문서의 표준인 XML이다. 본 논문에서는 문서의 변경이 발행한 경우에 문서 전체가 아닌 변경이 발행한 내용만 버전을 부여하고 저장함으로써 저장 공간을 절약하였다. 그리고 문서의 변경 내용이 일정한 크기 이하이면 JOIN 연산을 생략할 수 있도록 시스템을 설계함으로써 JOIN연산으로 인한 시스템의 성능 저하를 줄여 효율적인 XML 문서 저장과 빠른 검색 및 버전 관리가 가능한 방안을 제시하고, 이를 적용한 문서 저장 관리 시스템을 구현하였다. In rapidly changing an information=oriented society, it is essential to control massive document information by electronic file, In relation to these electronic document, it is also important to keep and maintain all kinds of information without any losses. It should be allowed to trace previous contents as well as recently updated contents by controlling updated contents with version. For these, XML is recommendable. In this thesis, we intend to save the document storing space by saving only updated contents with version without saving whole documentation, when document is updated. In case of controlling the history of document update by version, we designed system so as to omit “JOIN operation” if document size is under a certainspecific size. Therefore, we implemented a new XML document repository system which is possible for quick search and efficient XML document saving by reducing perfomance deterioration caused by JOIN operation.

Purpose: This study compared the value of ultrasonography(US) in the diagnosis of sternal fractures with those of conventional radiography and bone scan. Material and Method: From March 2000 to March 2001, in Gil Medical Center, Gachon Medical College, 44 patients(22 women and 22 men, mean age 46 years, range 5∼81 years) complained of tenderness in the sternal area. The cases histories of these patients with clinically suspected sternal fracture due to blunt trauma were prospectively studied. At the time of admission, conventional radiography(sternal view) was done. At one day after admission, sternal ultrasonography was obtained, and after 4∼5 days, a bone scan was done. Sternal ultrasonographic findings, conventional radiographic findings, and bone-scan findings were compared. In addition, a 12-lead ECG was done. When it was necessary, cardiac enzyme was checked and echocardiography was performed. Result: In 21 of 44 patients(48%), a sternal fracture was found by sternal US. Only 9 of 21 patients (43%) were diagnosed as having a sternal fracture by using conventional radiography. 23 of 44 patients (52%) have negative findings on sternal US; they also had negative findings on conventional radiography. Except for 7 unchecked patients, 13 of 21 patients(62%) were diagnosed as having a sternal fracture by bone scan, and among the 23 patients who had negative findings on sternal US, the 19 patients checked with a bone scan also had negative findings. Conclusion: Sternal US can find sternal fractures that are difficult to find on conventional radiography. Compared with bone scan, sternal US takes a shorter time and sternal US is not difficult. Additionally, combined lesions with sternal fractures(peristernal hematoma, soft tissue swelling) and costar cartilage fractures are diagnosed more easily when using sternal US.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

목적:본 연구는 병원감염의 주된 원인균인 MRSA의 병원 내 및 병원간의 전파양상을 파악하고, MRSA 균주 중 pathogen과 colonizer 간에 유전자형의 차이가 있는지 알아보고자 시행되었다. 방법:삼성의료원 중환자실에 1996년 1월에서 7월까지 입원한 26명의 환자로부터 분리되었던 MRSA 30균주와 서울대학교병원에서 1995년 9월에서 10월까지 37명의 환자로부터 분리되었던 MRSA 37균주, 그리고 단국대학교병원 신생아 중환자실에서 MRSA 감염증의 돌발적 발생에 연관되어 분리된 MRSA 균주 40주를 대상으로 하였다. 균주간의 상관성을 평가하기 위한 세균형별법으로 Pulsed field gel electrophoresis(PFGE, CHEF DR-II)를 이용하였고, 제한효소로 Smal I을 사용하였다. 결과:삼성의료원의 균주 30주 중 A 패턴이 10주(33.3%), B 패턴이 7주(23.3%)로 나타나, 주된 유행 균주가 있음을 확인하였다. 내과 중환자실에서 분리된 5 균주 중 4 주가 A패턴인 반면, 신생아 중환자실에서 분리된 9균주 중 4주가 B패턴에 속하여, 한병원내에서도 구역에 따라 유행균주가 다름을 알 수 있었다. 서울대학교병원 균주 중 23주(62.2%)가 동일한 A패턴으로 나타났고 단국대학교 병원 균쥬 중 27 균주(67.5%)가 B 패턴에 속하여, 세 병원의 MRSA 유행 균주 사이에 유전적 연관성이 있음을 시사하였다. Pahtogen과 colonizer간에 PFGE 패턴의 차이는, pathogen이 colonizer에 비해 유행균주에 많이 속하였으나 통계학적으로 유의한 차이가 없었다. 결론:PFGE를 이용한 세균형별법으로 분류한 MRSA 균주의 양상으로 볼 때, 한 병원 내에서 유행하는 MRSA 균주에는 소수의 주된 클론이 있었으며, 한 병원 내에서도 구역에 따라 유행균주는 서로 달랐다. 지역적으로 떨어져 있는 서울대학교병원과 단국대학교병원의 MRSA 유행균주는 삼성의료원의 유행균주 중 한 클론과 각각 일치하였다. 이 결과는 유행 MRSA 균주가 공동의 오염원에서 파급되어 지역적으로 다른 병원간에도 전파되고 있거나, 균주가 숙주의 요인에 의해 특정 MRSA 균주가 선택 분리되고 있을 가능성을 시사하였다. Background: Methicillin-resistant Staphylococcus aureus(MRSA) has become a major pathogen of nosocomial infection. In Korea, incidence of MRSA is alarmingly high up to 70-80% of total S. aureus strains isolated from teriary care hospitals. To investigate the mechanism of inra- and interhospital spread of MRSA, we evaluated the genetic relatedness of MRSA isolates recovered from 3 different hospitals in Korea. Methods:30 MRSA isolates obtained from Samsung Medical Center(SMC), 37 MRSA isolates from Seoul National University Hospital(SNUH) and 40 MRSA isolates from Dankook University Hospital(DUH) were classified into clonal types on the basis of pulsed field gel electrophoresis(PFGE). Results: Several PFGE patterns were predominant among the isolates from SMC(A-7/30[23.3%], B-6/30[20.0%], C-4/30[13.3%], G-3/30[10.0%]). The prevalent PFGE patterns were different between medical ICU(A-3/5[60.0%]) and newborn ICU(B-4/9[44.4%]0. The major clone of SMC. The major clone at DUH was PFGE type B, which was identical with another dominant clone of SMC. Although MRSA strains from SMC which caused clinical diseases belonged to major PFGE patterns more often than colonized strains, the association was not significant statistically. Conclusion: The presence of epidemic strains of MRSA suggests that epidemic MRSA clones may be originated from common sources and spread between different hospitals. Also, there may be virulence factors of stains or host factors, which could select specific strains.

An experimental study presents characteristics of combustion in a combustion chamber by port deactivation valve for economy and emissions standards. In order to use combustion properties data, it is necessary to build some data base, which use cylinder pressure sensor, etc. Port deactivation valve has been developed to satisfy requirement of achieving sufficient swirl generation to improve the combustion. A feasibility and necessity of combustion pressure based cylinder spark timing control has been examined. So, this was obtained the Coefficient of Variation(COV) and the mass-burned(MFB). The characteristics of pressure ratio fraction is similar to that of mass-burned fraction. Using the results of the test, the effects of the combustion chamber can be improved combustion stability by port deactivation.

Yang, Jae Hyuk,Barani, Rathinavelu,Bhandarkar, Amit Wasudeo,Suh, Seung Woo,Hong, Jae Young,Modi, Hitesh N.,Yang, Jae Hyuk by Lippincott Williams Wilkins 2014 Clinical journal of sport medicine Vol.24 No.4

OBJECTIVE:: To describe the changes in the spinopelvic parameters in weight lifters and evaluate the factors leading to spinal anatomical changes (eg, spondylolysis and listhesis). DESIGN:: Case–control study. SETTING:: Tertiary, institutional. PARTICIPANTS:: The study group participants were practicing weight lifters in the athletes’ village of the 2012 London Olympics. A total of 21 elite weight lifters were enrolled. Their data were compared with those of 45 healthy volunteers in the control group. INTERVENTIONS:: Comparative radiological evaluations were performed among the 21 elite weight lifters. Spinopelvic parameters (radiographic analysis), including total (TLL), upper (ULL), and lower (LLL) lumbar lordoses, sacral slope, pelvic tilt (PT) and incidence, lumbar index, and disc angles, were assessed. MAIN OUTCOME MEASURES:: The proportional ratio of ULL and LLL to TLL (ULL/TLL and LLL/TLL) was measured to describe the proportion effect. These values were compared with those of the control group. Weight lifters with and those without anatomical changes were subdivided into a deformed and nondeformed group, respectively, and further analyzed for differences. The correlation between these spinal parameters and the amount and duration of weight lifting training was also analyzed. RESULTS:: Anatomical changes in the lumbar spine were seen in 6 weight lifters (28.6%, P = 0.01). The mean TLL, ULL, and LLL values (59.8, 22.6, and 37.2 degrees, respectively) were increased, whereas PT (10.3 degrees) was decreased in the athletes compared with the volunteers (P = 0.001, 0.005, 0.07, and 0.018, respectively). The ULL/TLL was higher in the deformed group than in the nondeformed group (P = 0.036). The duration and amount of weight lifting training were not correlated with the spinopelvic parameters measured in this study. CONCLUSIONS:: The elite weight lifters had increased lumbar lordosis and decreased PT compared with the healthy volunteers. The ULL/TLL ratio may be used as a predictive marker for lumbar deformation.
