The primary and secondary survey was designed to identify all of a patient’s injuries and prioritize their management. However 15 to 22.3% of patient with missed injuries had clinically significant missed injuries. To reduce missed injury, special attention should be focused on patients with severe anatomical injury or obtunded. Victims of blunt trauma commonly had multiple system involvement. Some reports indicate that inexperience, breakdown of estalished protocol, clinical error, and restriction of imaging studies may be responsible for presence of missed injury. The best way of reducing clinical significant of missed injuries was repeated clinical assessment. Here we report a case of severe blunt hepatic injury patient and pericardial injury that was missed in primary and secondary survey. After damage control surgery of hepatic injury, she remained hemodynamically unstable. Further investigation found cardiac tamponade during intensive care. This was managed by pericardial window operation through previous abdominal incision and abdominal wound closure was performed. [ J Trauma Inj 2015; 28: 211-214 ]

Purpose: Thoracic aortic injury is a life-threatening injury that has been traditionally treated by using surgical management. Recently, thoracic endovascular aortic repair (TEVAR) has been conducted pervasively as a better alternative treatment method. Therefore, this study will focus on analyzing the outcome of TEVAR in patients suffering from a blunt thoracic aortic injury. Methods: Of the blunt thoracic aortic injury patients admitted to Eulji University Hospital, this research focused on the 11 patients who had received TEVAR during the period from January 2008 to April 2014. Results: Seven of the 11 patients were male. At the time of admission, the mean systolic pressure was 105.64±24.60 mm Hg, and the mean heart rate was 103.64±20.02 per minute. The median interval from arrival to repair was 7 (4, 47) hours. The mean stay in the ICU was 21.82±16.37 hours. In three patients, a chimney graft technique was also performed to save the left subclavian artery. In one patient, a debranching of the aortic arch vessels was performed. In two patients, the left subclavian artery was totally covered. In one patient whose proximal aortic neck length was insufficient, the landing zone was extended by using a prophylactic left subclavian artery to left common carotid artery bypass before TEVAR. There were no operative mortalities, but a patient who was covered of left subclavian artery died from ischemic brain injury. Complications such as migration, endovascular leakage, collapse, infection and thrombus did not occur. Conclusion: Our short-term outcomes of TEVAR for blunt thoracic aorta injury was feasible. Left subclavian artery may be sacrificed if the proximal landing zone is short, but several methods to continue the perfusion should be considered. [ J Trauma Inj 2015; 28: 232-240 ]

Pelvic bone fracture with unstable vital signs is a life-threatening condition demanding proper diagnosis and immediate treatment. Unlike long bones, the pelvic bone is a three dimensional structure with complex holes and grooves for vessels and nerves. Because of this complexity, a pelvic bone fracture can lead to complicated and serious bleeding. We report a case of a fifty-year-old male suffering from a pelvic bone fracture due to a fall. An imaging study showed fractures of both the superior and the inferior ramus of the pubic bone, with contrast extravasation underneath them, resulting in a large preperitoneal hematoma. He was sent for angiography, which revealed a hemorrhage from a branch of the left obturator artery. Embolization was done with a glue and lipiodol mixture. The patient recovered without complication, and was discharged at four weeks after admission. [ J Trauma Inj 2015; 28: 272-275 ]

An arteriovenous fistula (AVF) from the renal artery following a penetrating abdominal trauma is not common. We report the case of a 19-year-old male who presented with a knife stab wound in the right upper quadrant. Due to unstable vital signs and to the protrusion of the mesentery through the stab wound, providing definite evidence of peritoneal violation, an emergent exploratory laparotomy was carried out. There were injuries at the proximal transverse mesocolon and the second portion of the duodenum, with bile leakage. There was also a mild amount of retroperitoneal hematoma near the right kidney, without signs of expansion or pulsation. The mesocolon and the duodenum were repaired. After the operation, abdominal computerized tomography (CT) was performed, which revealed contrast from the right renal artery shunting directly into the vena cava. Transcatheter arterial embolization with a coil and vascular plug was performed, and the fistula was repaired. The patient recovered completely and was discharged without complication. For further and thorough evaluation of an abdominal trauma, especially one involving the retroperitoneum, a CT scan is recommended, when possible, either prior to surgery or after surgery when the patient is stabile. Furthermore, a lateral retroperitoneal hematoma and an AVF after a penetrating trauma may not always require exploration. Sometimes, it may be safely treated non-operatively or with embolization.

The production of abalone seed has grown and been specialized since the 2000s with the growth of the abalone farming industry. Despite the increase in the production of abalone seeds, the sales volume of abalone seeds remained flat and competition among producers increased. This paper will analyze the management efficiency of abalone seed production fishery to diagnose the management status and improve the abalone seed production efficiency. In addition, this study is the result of the basic research on the abalone seed industry and it is meaningful to prepare a platform for further research since the management status survey and the management efficiency survey of abalone seed production fishery have not been conducted until now. The data on the farmed fish prices of abalone seeds were collected from surveys of sample fish as part of the fish seed observation project conducted by the Fisheries Outlook Center (FOC) of Korea Maritime and Fisheries Development Institute (KMI). Management efficiency analysis utilizes DEA (Data Envelopment Analysis) model. The DEA model was analyzed by classifying into CCR (Super-CCR), BCC, and SBM (Super-SBM) models according to the assumptions taking into account the characteristics of the industry. The slack considered in the SBM model was judged as possible decreases in input variables and increase in output variables. The average efficiency from the CCR model was analyzed to be 69%. The BCC model was classified into input and output orientations, and the average efficiency was 79% and 75%, respectively. There were seven production fisheries with an SE value of 1 or more, which remained unchanged in terms of size and could be benchmarked. The average efficiency of the SBM model was 59% for CRS and 66% for VRS. Under the VRS assumptions, the variable increase/decrease efficiency analysis shows that labor costs can be reduced by 37.3%, facility capacity by 18.8%, and operating costs by 8.5%. In order to improve management efficiency, Wando needs to reduce labor and management costs. In Jindo region, sales increase as well as labor cost reduction is urgent. In other regions, reduced facilities and increased sales are recommended.

창의 교육을 위한 교육 공간의 융·복합적 특성 연구 -구성주의와 물리적 공간 구성의 관계를 중심으로-

남예진(Nam, Ye Jin),이선정(Lee, Sun Jung) 한국전시산업융합연구원 2021 한국과학예술융합학회 Vol.39 No.3

시간에 따라 사회의 변화와 교육과정의 변화는 빠른 속도로 진행된다. 본 연구는 그 속도에 맞춰 교육과정이 변화됨에 따라 이를 지원할 수 있는 교육 환경의 특성과 필요성에 관해 연구할 필요가 있다는 것에서 시작되었다. 본 연구의 목적은 창의성을 지원하는 교육 환경을 공간의 특성에 대해 분석하는 것이다. 따라서 본 논문은 선행 연구를 통해 창의성과 물리적 공간과의 연계성, 교육 공간 변화의 필요성을 도출하고, 창의성을 지원하는 공간의 특성을 도출하여 사례 분석을 이행하였다. 분석 과정을 통해 도출된 연구결과 및 내용은 다음과 같다. 창의성을 후천적 요소의 영향을 받는다. 또한 구성주의 학습이론은 습득된 지식은 개인의 해석과정을 거쳐 누적되며 그 해석과정에 있어 창의성이 발현된다고 본다. 더불어 해석과정에서는 물리적 환경의 지원 또한 필요하다는 것이다. 본 연구에서 도출한 창의 교육을 위한 물리적 교육 환경의 특성은 다음과 같다. 첫째, 경험을 통해 구성된 지식의 해석과정을 도울 수 있는 공간. 둘째, 호기심과 흥미를 자극하여 능동적인 학습 활동이 가능하게 하고, 문제해결과 창의적 활동을 유도하는 공간. 셋째, 상호작용이 유연하게 이뤄질 수 있는 공간, 넷째, 자유로운 사고와 실험적 태도를 촉진할 수 있는 입체적 공간. 위의 네 가지 특성을 갖춘 교육 공간의 제공하고 긍정적 효과를 얻기 위해서는 변화된 공간에 따른 교육 방식의 변화도 필요하다. 본 연구는 창의성을 지원하는 교육 공간의 뚜렷한 기준의 제시와 다양한 사례 분석에 있어 아쉬움이 남는다. 따라서 본 연구를 바탕으로 하여 심층적인 후속 연구를 진행할 예정이다. 사회는 교육과정 개정 속도에 비해 변화가 미비한 현실과 필요성을 인지해야 한다. 서울시 교육청에서 실시한 ‘꿈을 담은 교실’과 같이 교육 공간이 변화에 대한 움직임이 생겨나는 이 시점에서 창의성을 지원하는 공간의 특성에 관한 기준점이 되기를 기대한다. The pace of social change and educational process change is rapid. This study was initiated from the need for a study on the characteristics and necessity of an educational environment that can support the change in the educational process with speed. The purpose of this study is to analyze the characteristics of space in an educational environment that supports creativity. Therefore, this paper conducted case analysis by deriving the linkage between creativity and physical space, change of educational space, and deducing the characteristics of space that supports creativity through previous studies. The research results and contents derived through the analysis process are as follows. Creativity is influenced by factors of acquired factors. In addition, the constructivist learning theory sees that acquired knowledge is accumulated through an individual"s interpretation process, and creativity is expressed in the interpretation process. In addition, the support of the physical environment is also required in the analysis process. The characteristics of the physical education environment for creative education derived from this study are as follows. First, a space that can help the process of interpretation of knowledge constructed through experience. Second, a space that stimulates curiosity and interest, enables active learning activities, and induces problem solving and creative activities. Third, a space where interaction can take place flexibly, Fourth, a three-dimensional space that can promote free thinking and an experimental attitude. In order to provide an educational space with the above four characteristics and to obtain a positive effect, it is also necessary to change the educational method according to the changed space. This study leaves a disappointment in presenting a clear standard of an educational space that supports creativity and analyzing various cases. Therefore, based on this study, an in-depth follow-up study will be conducted. Society must recognize the reality and necessity of insufficient change compared to the speed of curriculum revision. It is expected that the educational space will become a reference point for the characteristics of the space that supports creativity at this point in time when there is a movement for change, such as the ‘Dream Classroom’ conducted by the Seoul Metropolitan Office of Education.

현재 급속하게 퍼져가고 있는 외래해충이면서 돌발해충인 갈색날개매미충 유충 및 성충의 천연살충제를 개발하기 위하여 엽침지법과 직접분무법을 이용하여 쑥(Artemisia vulgaris), 딜(Anethum graveolens), 자몽(Citrus paradisi), 티트리(Melaleuca alternifolia), 카제풋(Melaleuca leucadendron), 네롤리(Neroli bigarade) 및 만수국(Tagetes erecta)에서 추출한 정유성분을 이 용하여 살충효과를 실험하였다. 갈색날개매미충 유충에 대한 살 충효과는 엽침지법을 이용하여 72시간에 7종 정유성분을 각각 처리하였을 때에 쑥, 딜, 자몽, 티트리, 카제풋, 네롤리 및 만수 국 정유성분 순서별로 반수치농도(LC50)는 각각 251.02, 387.31, 286.21, 353.54, 275.64, 424.55, 165.68 mg/cm2 이며, 직접분무 법을 이용한 갈색날개매미충 성충의 반수치사농도는 각각 278.31, 402.11, 306.11, 379.64, 298.22, 459.56, 183.21mg/cm2으로 살충활성을 보였다. 이러한 연구결과를 바탕으로 만수국의 정유가 갈색날개매미충 유충 및 성충에 대하여 친환경 살충제 로써 적용 가능성을 보여주며, 더 나아가 식물체 정유성분을 이용한 외래해충 방제 기술을 응용한 제품의 다양화에 기여할 것 이다. The insecticidal toxicities of seven essential oils against Ricania sp. nymph and adults, newly recorded pest, were evaluated using leaf-dipping and spray methods. At 72 h exposure time, the LC50 values of the essential oils of Artemisia vulgaris, Anethum graveolens, Citrus paradisi, Melaleuca alternifolia, Melaleuca leucadendron, Neroli bigarade and Tagetes erecta were 251.02, 387.31, 286.21, 353.54, 275.64, 424.55, 165.68 mg/ cm2 when using the leaf dipping method against Ricania sp. nymphs, and 278.31, 402.11, 306.11, 379.64, 298.22, 459.56, 183.21 mg/cm2 when using the spray method against Ricania sp. adults, respectively. These results indicate that the essential oil of the Tagetes erecta can be potentially used as new natural insecticidal agents against Ricania sp. nymph and adults.
