Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

자연 대기에서 발생하는 낙뢰는 항공기에 용융, 소손 및 아크 등의 물리적인 손상을 발생시킬 뿐만 아니라, 낙뢰의 관통 과정에서 발생하는 기체 외부의 자기장은 기체 내부의 전자장비 및 배선에 전압 및 전류 과도현상을 발생시킨다. 이러한 효과는 항공기 내부의 항공전자시스템에 유도낙뢰를 발생시켜 안전한 비행을 불가능하게 한다. 본 논문에서는 표준감항인증 요구도를 만족하는 보호회로 설계 기법과 공인인증된 시험 결과를 소개하였다. Lightning causes physical damage to aircraft, such as melting, burning and arcing, and magnetic field that occurs on the aircraft’s outer body during the penetration of a lightning stroke causes voltage and current transients in the electronics and wiring within the aircraft. This effect will cause induced lightning strikes in the aircraft’s internal airborne electronic systems , preventing safe flight. This paper introduces protection circuit design techniques, and the test results that meet the requirements for certification of criteria.

<B>ABSTRACT</B><P>In this study, we aimed to evaluate the microbiological risk of pork and chicken by-products by enumerating indicator bacteria (total aerobic bacteria, coliforms, and Escherichia coli) and identifying pathogens such as Campylobacter and Salmonella. The antibiotic resistance of pathogenic isolates was determined, and molecular subtyping was performed using automated repetitive sequence-based PCR (rep-PCR). Pork and chicken by-products were collected from 10 processing plants. The mean numbers of total aerobic bacteria, coliforms, and E. coli from 95 pork by-product samples and 64 chicken by-product samples were 5.1, 3.6, and 2.4 log CFU/g and 4.5, 3.0, and 1.8 log CFU/g, respectively. The numbers of indicator bacteria in the gastrointestinal tract (small intestine, large intestine, and gizzard) were significantly higher than those in other organs. Salmonella and Campylobacter species were detected in 3 and 5 of 95 pork by-product samples and in 6 and 3 of 64 chicken by-product samples, respectively. Four of 9 Salmonella isolates examined were resistant to eight antibiotics, and each of these resistant strains produced an extended-spectrum β-lactamase. Most Campylobacter isolates were resistant to tetracycline (7 of 8 strains) and quinolones (7 of 8 strains). The similarity in rep-PCR patterns among Salmonella isolates was more closely associated with serotype than with the processing plant and type of meat. Conversely, the rep-PCR patterns of Campylobacter isolates were specific to the processing plant. Our findings could help agencies develop regulations for protection from foodborne bacterial infections arising from animal by-products.</P>

Objective: The study’s aim was to develop and standardize a Korean version of the University of California San Diego Performance-based Skills Assessment (K-UPSA), which is used to evaluate the daily living function of patients with schizophrenia. Methods: Study participants were 78 patients with schizophrenia and 27 demographically matched healthy controls. We evaluated the clinical states and cognitive functions to verify K-UPSA’s reliability and validity. For clinical states, the Positive and Negative Syndrome Scale, Clinical Global Impression-Schizophrenia scale, and Social and Occupational Functioning Assessment Scale and Schizophrenia Quality of Life Scale-fourth revision were used. The Schizophrenia Cognition Rating Scale, Short-form of Korean-Wechsler Adult Intelligence Scale, and Wisconsin Card Sorting Test were used to assess cognitive function. Results: The K-UPSA had statistically significant reliability and validity. The K-UPSA has high internal consistency (Cronbach’s alpha, 0.837) and test-retest reliability (intra-class correlation coefficient, 0.381-0.792; p<0.001). The K-UPSA had significant discriminant validity (p<0.001). Significant correlations between the K-UPSA’s scores and most of the scales and tests listed above demonstrated K-UPSA’s concurrent validity (p<0.001). Conclusion: The K-UPSA is useful to evaluate the daily living function in Korean patients with schizophrenia.
