Purpose: We should prepare proper medical service for disaster control as South Korea is not free from terrorism and war, as we experienced through the two naval battles of the Yeonpyeong, one in 1999 and the other in 2002, the sinking of Cheonan in 2010, and the attack against the border island of Yeonpyeong in 2010. Moreover, North Korea`s increasingly bellicose rhetoric and mounting military threats against the world demand instant action to address the issue. The aim of this article is to describe our experience with three patients with combat-related gunshot and explosive injuries to their extremities and to establish useful methods for the management of patients with combat-related injuries. Methods: Three personnel who had been injured by gunshot or explosion during either the second naval battle of the Yeonpyeong in 2002 or the attack against the border island of Yeonpyeong in 2010 were included in our retrospective analysis. There were one case of gunshot injury and two cases of explosive injuries to the extremities, and the injured regions were the left hand, the right foot, and the right humerus. In one case, the patient had accompanying abdominal injuries, and his vital signs were unstable. He recovered after early initial management and appropriate emergency surgery. Results: All patients underwent emergent surgical debridement and temporary fixation surgery in the same military hospital immediately after their evacuations from the combat area. After that, continuous administration of antibiotics and wound care were performed, and definite reconstructions were carried out in a delayed manner. In the two cases in which flap operations for soft tissue coverage were required, one operation was performed 5 weeks after the injury, and the other operation was performed 7 weeks after the injury. Definite proce dures for osteosynthesis were performed at 3 months in all cases. Complete union and adequate functional recovery were achieved in all cases. Conclusion: The patient should be stabilized and any life-threatening injuries must first be evaluated and treated with damage control surgery. Staged treatment and strict adherence to traditional principles for open fractures are recommended for combat-related gunshot and explosive injuries to the extremities.

Purpose: We analyzed the medical costs for severely traumatized patients according to the severity and medical performance so that we couldimprove the financial balance of the trauma center. Methods: Retrospective analysis was performed on patients visiting SNUH Trauma Center from May 2011 to August 2011. Among a total of 55 severely traumatized patients, 31 patients whose medical bills were available and categorized were included in this study. The injury severity score (ISS) was calculated from the abbreviated injury score (AIS), which was updated in 2008,for each patient to assess the severity of injury. Major trauma was defined as an ISS above 15. Results: The 31 patients in this study included 20 males and 11 females. The average ISS was 33.23±16.65 points. We categorize the patients into three groups according to ISS, 16-24: group 1, 25-40: group 2, and above 41: group 3. Total incomes, admission fees, surgery fees, and imaging test fees are shown in table 1. The costs seem to be higher costs in group 2, but this result has no statistical significance. Statistical significantly data are as follows: high radiologic test fees in group 1, short hospital stay in groups 1 and 2, and short ICU stay in group 1. The averagehospital stay was 17 days, and the average emergency intensive care unit (EICU) stay was 7.5 days. Although the EICU stay was only 44% of the total hospital stay, the income from the EICU covers 79.4% of the total hospital income. Conclusion: From this study, we found several items that show relatively high medical income from severely traumatized patients visiting the SNUH Trauma Center. Most of the medical fees arise in the early phase of acute medicine usually in the ICU. Efforts to identify the items with high income and to minimize expenses will improve the financial structure of the Trauma Center, which is facing a budget crisis.

Purpose: The objective of this study was to investigate the appropriateness of the cross table lateral cervical X-ray used in the emergency department for severely traumatized Korean patients. Methods: Patients visiting our institution from May 2011 to May 2012, who had injury severity score (ISS) > 15 and who received a cervical X-ray in the emergency department, were included in this study. Data including demographics, ISS score, GCS score, and place where the x-ray was taken were collected to evaluate their relationship with appropriate coverage of the cervical X-ray. The appropriateness of a cervical cross lateral view Xray was evaluated using exposure of the basion, and the opisthion, as well as the distal level of exposure. Results: Fifty-two patients were included in this study. The identification rate of the basion was 79.2%, and the identification rate of the opisthion was 88.7%. Complete exposure of C7/T1 was accomplished in 3.8% of the patients. The ISS was higher for X-ray taken in the trauma bay, but the range of exposure showed no difference between the places where the X-rays taken. Patients who had exposure of C 5/6 or more had lower body weight and body mass index (BMI) compared with unexposed patients. Conclusion: In severely traumatized Korean patients, the adequacy of the cross table lateral cervical X-ray was inappropriate in most cases. No difference was observed in the exposure range between the places where the X-rays were taken, and patients with less exposure showed higher body weight and higher BMI.

2016년에 쌍별귀뚜라미는 식품의약품안전처 식품공전에 등록된 식품원료로 가장 큰 장점은 월동 없이 연중 대량 사육이 가능하다는 것과 60% 이상의 단백질 함량이다. 본 연구에서는 사육공간, 인건비 등의 문제로 인하여 귀뚜라미 사육이 불가능할 때를 대비하여 저장조건을 설정하였으며, 산란율이 높은 산란처 선발과 알의 동종포식률을 조사하였다. 산란은 상토 산란처에서 가장 선호도가 높았으며(p < 0.05), 알의 동종포식률을 보았을 때 10 L 당 종령 약충 62마리 이하, 1일 동안 산란을 받는 것이 가장 적합한 것으로 판단되었다(p < 0.05). 알의 저온 저장을 하였을 때는 28℃에서 10일간 보관 후 16℃에서 10일간 저온 저장했을 때 부화율이 가장 높았고, 저장을 하지 않았을 때와 비교하였을 때 12~14일 부화를 연장할 수 있었다(p < 0.05). 쌍별귀뚜라미의 산란처, 산란 방법 및 알 저장조건을 설정함으로써 효율적인 생산방법을 제시하였다. In 2016, the two-spotted cricket was approved as a general food ingredient by the Korean Ministry of Food and Drug Safety. Additionally, the two-spotted crickets have high protein content (60%) and can be reared throughout the year even during the overwintering period. In this study, storage conditions were set in case cricket breeding was not possible due to problems such as breeding space and labor costs, and selection oviposition mats to determine high fecundity rates and low cannibalism rates for the eggs were investigated. The oviposition mat was mostly composed of soil (p < 0.05). Less than 62 crickets per 10 litters were found to be best suited for 1 day of spawning, based on the cannibalism rate of the eggs during the egg laying period. The results from the hatched eggs indicated that the hatching extended 12 to 14 days, and the best hatching rate was approximately 85% when stored at low temperatures(16℃) for 10 days. An efficient production proposed method that established the best oviposition mat and egg storage method for the cricket.
