This paper is to analyze the effectiveness of multistatic sonar network based on detection performance. The multistatic sonar network is a distributed detection system that places a source and multi-receivers apart. So it needs a detection technique that relates to decision rule and optimization of sonar system to improve the detection performance. For this we propose a data fusion procedure using Bayesian decision and optimal sensor arrangement by optimizing a bistatic sonar. Also, to analyze the detection performance effectively, we propose the environmental model that simulates a propagation loss and target strength suitable for multistatic sonar networks in real surroundings. The effectiveness analysis on the multistatic sonar network confirms itself as a promising tool for effective allocation of detection resources in multistatic sonar system.

<B>Purpose: </B>Although the diagnostic accuracy of thyroid cancer by fine needle aspiration cytology (FNAC) is increasing, there are some nodules for which ultrasonography and FNAC show indeterminant. The purpose of this study was to determine the usefulness of thyroid ultrasonography by the surgeon prior to operation <B>Methods:</B> Forty-nine patients who underwent thyroid operations between June 2006 and January 2007 were selected for this study. Thyroid ultrasonography was performed on each patient.And we recorded and analyzed the shape and the margin of the nodule, internal echogeneiety, heterogeneiety, the presence of microcalcification, height versus width, and the presence of level VI lymph node larger than 3 mm, assigning each a score of 1, 2 or 3. <B>Results: </B>The average score was 17.1. Assuming an average score over 14 is considered to be malignant, the sensitivity, specificity, positive predictive value, and negative predictive value were 95.6%, 88.9%, 91.7%, 94.1% respec</B>tively. Statistically significant characteristics of malignancy were the shape and the margin of the nodule, internal echogeneiety, microcalcification, taller than wide shape and the presence of enlarged VI lymph nodes. The heterogeneiety had no significant P value. <B>Conclusion: </B>When malignancy cannot be confirmed even after repeated FNAC, preoperative ultrasonograpy performed by surgeons can be a reliable test and helpful for operations. <B>(Ko</B><B>rean J Endocrine Surg 2008;8:28-32)</B>

Bilateral chylothorax as a complication of modified radical neck dissection is extremely rare, but it is potentially serious and sometimes fatal. Early diagnosis and proper management is very important. We report here on a case of bilateral chylothorax following left modified radical neck dissection that was successfully treated with conservative management. (Korean J Endocrine Surg 2006;6:32-34)

The purpose of this study was to effects of the endurance exercise intensity on the Body weight and obesity index in rats. 84 male white rat of Sprague-Dawley(6 week of age) were divided into the three group; control group(COG; n=28), low intensity(20m/min) trained group(LTG; n=28), and high intensity(28m/min) trained group(HTG; n=28). The adaptation training to the environment and the adaptation training to the treadmill running were performed for one week, with the exercise program 5 times/week during 12 week. Following are the results of the research. The Body weight and food efficiency ratio were significant differences between exercise group and control group in 8 weeks and 12 weeks. There were significant differences on obesity index and fat mass change of control group, low intensity exercise group and high intensity exercise group in 4 weeks and 8 weeks, and significant difference between exercise group and control group in 12 weeks. Also, adipose tissue size and number were significant differences between exercise group and control group in 12 weeks. In conclusion, regular endurance exercise of 12 weeks have a meaningful influence on Body weight loss and obesity index but the different intensity of the exercise seemed to have no significant differences. It is suggested that when consider exercise program for obese person, there should be enough time for increase of energy consumption than exercise intensity.

이 논문은 축구선수의 포지션이 심폐기능과 경기 중 운동강도, 이동거리에 미치는 영향을 검증한 연구였다. 연구대상은 2009년 K3 리그에 참여하는 W팀의 선수 40명을 FW(n=12), MF(n=12), DF(n=16)로 구분하였다. 연구목적을 달성하기 위해 경기장을 4등분하였으며, 비디오카메라 4대를 고정하여 촬영한 후 영상분석을 실시하였다. 자료처리는 SPSS 통계 package를 이용하여 one-way ANOVA로 분석하였다. 연구결과, 심폐기능 요인인 최대산소섭취량과 운동지속시간(MF, FW > DW)에서 통계적으로 유의한 차이가 있었고( p<.05), 무산소 성역치시간(MF > FW > DF)은 각각의 포지션에 따라 통계적 유의한 차이가 있었다( p<.05). 경기 중 운동강도 차이는 HRminimum(DF > MF, FW), HRaverage(DF, MF > FW)에서 통계적으로 유의한 차이가 있었다 ( p<.05). 또한 이동거리 형태의 경우 워킹(MF > FW, DF), 조깅(MF > DF, FW), 스프린트(MF, FW > DF), 백스텝(DF > MF, FW), 사이드스텝(DF > FC, MF), 총 이동거리(MF > FW, DF)에서 통계적으로 유의한 차이를 보였다( p<.05). 결론적으로 축구 포지션의 특성이 심폐기능 요인과 경기 중 운동강도 및 이동거리에 영향을 미친다는 것을 확인하였다. 경기력 향상을 위해 포지션 특성에 맞는 보다 높은 체력훈련 프로그램 개발과 적용이 필요한 것으로 생각된다. This study verified effect of different player positions on cardiopulmonary function, exercise intensity and moving distance during games in soccer. As a subject of study, 40 players of W team participated in 2009 K3 League were classified into FW(n=12), MF(n=12), DF(n=16). To achieve the purpose of study, the stadium was quadrisected and 4 cameras were fixed to make a video recording for conducting visual analysis. The date processing was analyzed as one-way NANOVA using SPSS statistical package. The result of the study shows that there were statistically significant difference between V˙ O2max and exercise duration(MF, FW > DF). Also, cardiopulmonary function(p<.05), and anaerobic threshold time(MF > FW > DF) showed statistically significant difference by each position(p<.05). Exercise intensity showed statistically significant difference on HRminimum(DF > MF, FW), HRaverage(DF, MF > FW) during a soccer game(p<.05). And the moving distance showed statistically significant difference on working(MF > FW, DF), jogging(MF > DF, FW), sprint(MF, FW > DF), back-step(DF > MF, FW), side-step(DF > FC, MF), total moving distance(MF > FW, DF) (p<.05). In conclusion, it is confirmed that the features of soccer position has effect on cardiopulmonary function and exercise intensity during a game. The development and application of higher strength training program is thought to be necessary for the improvement of athletic performance.

목 적: 본 연구는 대퇴골 전자간 골절 환자를 대상으로 TRIGENTM INTERTAN nail (InterTAN)이 제2형 항회전 근위 대퇴골수정(proximal femoral nail antirotation 2, PFNA2)에 비해 우수한 임상결과를 보이는지 여부를 확인하고자 하였다. 대상 및 방법: 2009년 3월부터 2013년 12월까지 대퇴골 전자간 골절로 내원하였던 환자 중 연구 포함 기준을 만족시키는 164명을 대상으로 하였다. InterTAN군과 PFNA2군 간의 수술 시간, 출혈량, 술 후 방사선적 결과, 합병증 및 최종 추시에서의 임상결과를 비교 분석하였다. 결 과: InterTAN군에서 골유합률 및 골유합까지의 기간, 최종 추시에서 두 군 간의 임상결과는 유의한 차이가 없었다. InterTAN군에서 tip apex distance가 유의한 수준으로 길었으며(p<0.05), PFNA2군에서 근위 대퇴골의 외측벽 골절 빈도가 유의한 수준으로 높게 나타났다(p<0.05). 근위 골편의 활강은 PFNA2군에서 유의한 수준으로 높았다(p<0.05).결 론: InterTAN군과 PFNA2군은 두 군 모두 우수한 유합률을 보이며, 임상 결과는 InterTAN군이 PFNA2군보다 우수하지 않고 비슷한 결과를 보였다. Purpose: The primary purpose of this study was to demonstrate that the TRIGEN (TM) INTERTAN nail (InterTAN) could show better clinical outcome compared to the proximal femoral nail antirotation 2 (PFNA2) for treatment of intertrochanteric fracture in the elderly. Materials and Methods: Between March 2009 and December 2013, 164 patients with intertrochanteric fractures who met our inclusion and exclusion criteria were enrolled in this study. Evaluation variables, including operation time, blood loss during the operation, incidence of perioperative complications, clinical results at the last follow-up, and radiographic findings were assessed for comparison of the 2 implants. Results: Intraoperative lateral wall fracture was significantly higher in the PFNA2 group (p<0.05) and tip apex distance was significantly higher in the InterTAN group (p<0.05). Sliding of the proximal fragment at the last follow-up was significantly higher in the PFNA2 group. However, there was no significant difference in union rate, time to union, postoperative complications, and clinical outcomes at the last follow-up between the 2 groups. Conclusion: Based on these data, clinical outcomes at the last follow-up were equivalent between InterTAN and PFNA2.
