In this paper, it has been proposed an automatic vegetable bundling mechanism that makes use of heat melt sticking. The proposed mechanism is consisted of three modules for the rationality of manufacture. Design specification has been determined by the bundling mechanism that was optimized mechanically. And, it has been manufactured the prototype of the automatic bundling machine. It has been carried out directly the field test for verification of performance in farmhouse which produces vegetable. In field test, this bundling machine showed efficiency of about 3.6 times than the manual working by manpower, and other performance it got satisfied result. This automatic vegetable-bundling machine was already registered as the agricultural machine. and This machine will be commercialized soon.

The study was conducted to determine the effectiveness of the triage training program utilizing pre-and post-training experiments designed for 119 emergency medical services teams. Objectives: This study evaluated the effectiveness of triage training programs on the accuracy of triage performed by 119 emergency medical services team staff who participated in the triage training program. Behavior: Participants in this study included 119 of the 166 EMS staff. In this program, a modified START triage consisting of a 20-minute theoretical presentation was presented to the participants. Data were analyzed using SPSS 21.0. Results: A significant increase in triage accuracy for 119 EMS teams(p<.001). And undertriage showed a significant decrease(p<.001). In addition, overtriage showed a decrease but was not statistically significant. Conclusions: The results obtained from this study showed that the triage training program was effective in improving the accuracy of the triage of multiple injury patients or disaster victims when presented to the 119 emergency medical services team. Therefore, these results suggest that it would be helpful to add triage training to the fire department's formal training program.

총담관결석의 진단방법은 여러 가지가 있으며 크게 임상양상, 영상검사 및 내시경검사로 나눌 수 있다. 이 중에서 임상증상, 검사실 소견, 초음파검사 또는 복부전산화단층촬영과 같은 기본 검사 결과를 바탕으로 총담관결석이 있을 가능성이 높은 군과 낮은 군으로 구별 혹은 층화하여 몇 개의 위험군으로 나누어 치료 방침 및 추가 검사를 시행한다. 저위험군에서는 환자가 담낭담석을 동반하여 담낭절제술이 필요하다면 내시경역행담췌관조영술을 시행하지않고 바로 담낭절제술을 시행할 수 있다. 중등도 위험군에서는 총담관결석의 제거를 위한 내시경역행담췌관조영술이 필요한지를 알아보기 위하여 자기공명 담췌관조영술이나 내시경초음파검사의 추가 검사가 필요하다. 고위험군에서는 다른 추가 검사 없이 담석 제거 등의 치료를 할 수 있는 내시경역행담췌관조영술을 바로 시행할 수 있다. Choledocholithiasis is the presence of at least one gallstone in the common bile duct.Symptoms may be variable ranging from asymptomatic to complications such as cholangitis, sepsis, pancreatitis. Wherever patients have symptoms and investigation suggests ductal stones, extraction should be performed if possible. The approach to patients with suspected choledocholithiasis requires careful consideration because missed common bile duct stones pose a risk of complication. Under these circumstance, guidelines have been prepared in some countries and these criteria are now being evaluated. In this review, we are going to suggest the guideline of Korean Pancreatobiliay Association for adequate diagnosis and risk stratification of common bile duct stones.

저자들은 골수 이형성 증후군으로 외래에서 추적관찰 중이던 환자에서 혈액 검사와 골수 검사 결과 급성 골수성 백혈병으로의 전환기에 위벽에서 발생한 과립구성 육종 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma is a localized tumor that`s composed of immature cells of the granulocytic series. The tumor may be involved anywhere in the body, but we present here a rare case that involved the gastrointestinal tract (and especially the stomach). Granulocytic sarcoma may represent the initial manifestation of blast transformation or it may herald the onset of acute leukemia from myelodysplastic syndrome. We report here on a case of gastric granulocytic sarcoma in a patient with transformed acute leukemia from myelodysplastic syndrome. A 56-year-old male who was suffering with myelodysplastic syndrome (RARS) for 5 years presented with upper abdominal pain. Gastrofiberoscopy revealed an elevated lesion with central erosion at the posterior wall of the gastric upper body, which histologically proved to be a granulocytic sarcoma. The peripheral blood smear and bone marrow examination showed acute myeloid leukemia.(Korean J Med 74:570-573, 2008)

In this paper, we propose an automatic vegetable-bundling mechanism that makes use of heat melt sticking. The proposed mechanism is made of three modules for aligning, shaping, and bundling. Using the SMO(SimDesigner Motion) module, we optimize condition of mechanical movement of the bundling mechanism. We manufactured the prototype of the automatic bundling machine. Also we carried out directly the field test for verification of performance in farmhouse which produces vegetable, and we got satisfied result. This machine will be commercialized and announced soon.

Paragangliomas are rare tumors that arise from the extraadrenal chromaffin cells. We report here on a case of retroperitoneal paraganglioma in a 24-year-old young man. Abdomen CT and magnetic resonance imaging showed a hypervascular mass near the left ureter. He had not felt paroxysmal palpitation and his vital signs were within the normal range. An exploratory laparotomy revealed a 7.2×5.5 cm sized mass below the jejunum and near the aorta, and this mass had adhesion to the left ureter. It was histologically diagnosed with a paraganglioma after the surgical resection. Although there was an increase of blood pressure on palpation during surgery, the postoperative course was uneventful. When we consider the unusual locations and the associated operative risk, we should take care to rule out the possibility of a functional paraganglioma in the preoperative differential diagnosis of an abdominal mass.
