Purpose: To evaluate the clinical outcomes and radiographic results of open reduction and internal fixation for intraarticular calcaneal fractures. Materials and Methods: We reviewed 20 cases of calcaneal fractures managed with open reduction and internal fixation from March 2003 to January 2005. We used the computed tomographic classification system proposed by Sanders et al to classify these fractures. Preoperative and postoperative Bohler's angle, heel height (calcaneal facet height) and calcaneal length, calcaneal width were measured. The Creighton-Nebraska Health Foundation Assessment score was used for clinical evaluation. Results: There were 12 cases of type II fractures, 5 of type III fractures and 3 of type IV fractures. The mean clinical score was 84.3 for type II, 82.6 for type III and 56.1 for type IV. The mean preoperative $B{\ddot{o}}hler$ angle was $6.1^{\circ}$ and final was $22.8^{\circ}$. The mean preoperative calcaneal facet height was 76.6 mm and final was 80.3 mm (The mean calcaneal facet height was changed from preop 76.6 mm to postop 80.3 mm). The mean preoperative calcaneal length was 88.2 mm and final was 92.6 mm. The mean preoperative width was 38.1 mm and final was 35.6 mm. Conclusion: Open reduction and internal fixation showed good results for type II and III fractures, but for type IV fractures the clinical result was significantly worse than the other types. However, type IV fractures still had restoration of (should be restored in) $B{\ddot{o}}hler's$ angle, calcaneal facet height, calcaneal length and width which may be helpful in later subtalar fusion.

Sewage pumps are designed with a wide flow channel by, for example, sacrificing some efficiency and reducing the number of blades, in order to prevent plugging with foreign bodies. However, the behavior of foreign bodies which actually flow into a pump is extremely complex, and there are questions about whether the presumed foreign bodies will actually pass through. This paper proposes a new type of sewage pump impeller designed to further improve pump efficiency and performance in passing foreign bodies. This sewage pump impeller has a structure in which the suction flow channel of a closed type non-clog pump is wound in a helical spiral. The focus of this research was to investigate pump performance and internal flow in this single blade sewage pump impeller. The results clearly indicated the following facts: The developed sewage pump impeller exhibits high efficiency over a wide range of flow rates; internal flow of the pump is very complicated; and the internal flow state varies greatly when the flow rate changes.

Objectives: This study was designed to investigate the anti-obesity, anti-diabetic and anti-inflammatory effects of Platycodi radix on obese type 2 diabetes mouse model. Methods: Obese type 2 diabetes mouse model was induced by Surwit's high fat, high sucrose diet for 8 weeks. Models were divided into 4 groups of normal diet (ND, n=10), high fat and high sucrose diet (HFD, n=10), high fat and high sucrose diet with Platycodi radix (PR, n=10), and high fat and high sucrose diet with Metformin (Met, n=10). Body weights were measured every week. After 7 weeks fasting, blood sugar and oral glucose tolerance tests were conducted. After 8 weeks blood samples were taken from mouse hearts and analyzed biochemically. Lipid profile, fructosamine, leptin and weight of epididymal fat pad and liver were measured. Adipose tissue macrophage percentage was analyzed by fluorescence-activated cell sorting (FACS). Results: Compared with the HFD group, body weight, glucose level, fructosamine, weight of epididymal fat pad and adipose tissue macrophage percentage decreased in the PR group. Conclusions: These results suggest that Platycodi Radix has anti-obesity, anti-diabetic, and anti-inflammatory effects on obese type 2 diabetes mouse model.

본 증례는 일본에서 과민성 폐장염의 원인 중 가장 높은 비율을 차지하고 있는 T. cutaneum에 의한 summer-type hypersensitivity pneumonitis가 우리나라에서 밝혀진 첫번째 예로서, 가정에 있을 때만 증상이 나타난 점, T. cutaneum에 대한 침전 항체가 양성으로 나온 점, 스테로이드 투여 후 증상 및 폐기능, 방사선 소견 등이 회복된 점 등을 볼 때 이 질환으로 진단할 수 있었다. 일본과 유사한 기후가 있는 우리나라에 있어 이 질환의 존재 가능성은 높을 것으로 생각되는데 앞으로 이 질환에 대한 연구가 요망된다.

Gastric cancer is histologically classified into two types. One is the intestinal and diffuse type according to Lauren's classification, and the other is the differentiated and undifferentiated type based on Nakamura's classification. In 2007, Japanese groups proposed a new type of well-differentiated gastric adenocarcinoma in the gastric fundic glands with distinct endoscopic and clinicopathologic features. This is gastric adenocarcinoma of the fundic-gland type (GA-FG), a rare variant of gastric cancer. In a 2012 Korean study, of 6,000 cases of gastric cancer tissues, only three cases of GA-FG were identified. GA-FG is usually located in the upper third of the stomach and not known to be associated with the Helicobacter pylori infection. We herein report a case of GA-FG diagnosed in a 63-year-old man. A gastric polyp was incidentally detected during an upper endoscopy screening while conducting a health check-up, and he was diagnosed with GA-FG after an endoscopic mucosal resection (EMR) was conducted for diagnostic and therapeutic purposes. Our case suggests that for both diagnostic and therapeutic purposes, EMR may be beneficial in case of gastric polyps with suspected GA-FG.

Multiple robotics systems with several sub-chains have a characteristic that grasp a common object with internal loading not to loose the grip. The investigation for the internal loading of a triple manipulator has been few as compared to a dual manipulator. In this paper, type of the internal loading for a triple manipulator system is investigated through analysis of the null space of the system. Several types of the internal loading are shown for general planar and spatial type triple robots, which rigidly grasp the common object. The general scheme is applied to analysis of the internal loading for the three-fingered and three-legged robots having a point contact with the grasped object.

본 논문에서는 고농도$\cdot$고수율 오존발생기를 개발할 목적으로 망사형 내부전극과 무성방전의 중첩을 이용한 중첩방전형 오존발생기를 설계$\cdot$제작하였다. 중첩방전형 오존발생기는 방전공간에 3개의 전극(중심전극, 내부전극 및 외부전극)과 2개의 gap(중심전극과 내부전극 사이의 gap과 내부전극과 외부전극 사이의 gap)으로 구성되어있다. 중첩방전형 오존발생기의 중심전극을 공통접지하고 내부전극과 외부전극에 $180{[^\circ]}$의 위상차를 가진 역극성의 교류 고전압을 각각 인가하면 각각의 방전 gap에서 발생하는 무성방전이 중첩되면서 오존이 발생된다. 이때, 내부전극의 조밀도가 증가할수록 방전전극의 면적이 확대되고 방전공간의 전력밀도가 억제되어 오존생성특성이 상승하였다. 그 결과 최대 17,720[ppm], 5.4[g/h] 및 250[g/kwh]의 오존을 얻을 수 있었다.
