사이드 스캔 소-나를 이용한 해저면 음향영상자료의 처리과정에서 가장 첫 번째 단계는 수중예인체의 절대위치를 결정하는 것이다. 예인체를 조사선박에 부착하지 않고 후미에서 수중예인하기 때문이다. 수중에서 음향을 이용하여 위치를 추적하는 장치나 예인체의 움직임을 관측하는 추가적인 지원장비 없이도 절대위치를 계산할 수 있는 기술적인 알고리즘이 제안되었다. 예인항적으로 작성된 모자이크 결과도면에서, 인접한 측선 간의 불일치나 모호하게 접합되는 해저형태를 발견할 수 없었다. 절대위치 계산과정에서 수중예인체의 진행방향이 부드럽게 되는 부차적인 효과가 있다. 그 결과 진행방향에 대하여 수직으로 분포하는 영상자료의 펼침형태가 안정적으로 배열되며 음향조사역(音響照射域)의 평면투영에서 자료의 유실현상도 현저하게 줄어든다. 수중에서 예인하는 방식의 다른 분야 해양조사에서도 이 연구결과의 적절한활용이 기대된다.

We report a rare synchronous presentation of primary lung cancer and adrenal pheochromocytoma. A 59-year-old woman was diagnosed with right upper lobe non-small cell lung carcinoma measuring 2.8 cm and a right adrenal gland mass measuring 3.5 cm, which displayed increased metabolic activity on $^{18}F$-fluorodeoxyglucose positron emission tomography-computed tomography. The adrenal lesion was revealed to be asymptomatic. The patient underwent right adrenalectomy and histological examination revealed a pheochromocytoma. Ten days later, right upper lobectomy was performed for lung cancer. This case indicates that incidental adrenal lesions found in cases of resectable primary lung cancer should be investigated.

Splenosis is defined as an autotransplantation of the splenic tissue after splenic rupture or splenectomy, and occurs most frequently in the peritoneal cavity. Splenosis is usually asymptomatic and is found incidentally. We report a case of combined intrathoracic and intraperitoneal splenosis in a 54-year-old male who worked as a miner for 10 years in his twenties, and was a current smoker. He was referred to our hospital for further evaluation of an incidental left diaphragmatic mass. Positron emission tomography-computed tomography and bronchoscopy were performed to evaluate the possibility of malignancy. There was no evidence of malignancy, but the spleen was not visualized. Reviewing his medical history revealed previous splenectomy, following a dynamite explosion injury. Therefore, splenosis was suspected and technetium-99m-labeled heat-damaged red blood cell scan confirmed the diagnosis. Radionuclide imaging is a useful diagnostic tool for splenosis, which could avoid unnecessary invasive procedures.

재태 38주에 시행한 산전 검사상 우연히 발견된 거미막 낭종을 가지고 태어난 생후 2개월된 여아가 지속적인 과민상태를 나타내었다. 이후 시행한 두부 전산화 단층촬영상 수두증을 동반하여 크기가 증가된 거미막 낭종이 관찰되었다. 우리는 상기 소견에 대하여 개두술하에 낭종 개창술을 시행하였으나 낭종의 크기가 줄어들지 않았고, 13개월 이후에 시행한 경과관찰에서 수두증이 악화된 소견을 보였다. 환아는 이후 낭종-복막간 단락술을 시행하였으며, 5년뒤 시행한 두부 자기공명영상에서 낭종의 크기 감소와 더불어 뇌수두증이 해소되었다. 거미막 낭종 자체의 크기가 증가하는 것은 드문 현상이며, 아직까지 이에 대한 명확한 수술적 치료는 나와 있지 않다. 우리는 이 증례를 통하여 수두증이 동반된 크기가 증가하는 거미막 낭종의 치료에 있어서 낭종-복강간 단락술이 적절한 수술적 치료법이 될 것으로 판단한다.

The goal of this study was to investigate the distribution chart of management and satisfaction through Hanwoo education program and to provide fundamental data and development conformity available on the management and educational program to managers. In this study, we chose 75 managers taking part in Hanwoo education program as pre-test and applied satisfaction for education program to 33 managers randomly selected as post-test. The results of this study are as follows: First, age and academic career had a significant (P<0.05) effect on breeding size, breeding career, sales, and management methods. This may be due to the fact that managers in Hanwoo industry tended to raise academic standards and the age group moved towards young age rather than middle and old ages. However, an academic career was unaffected by sale and management methods. Second, managers who randomly selected the education program showed higher satisfaction about the program and lower or usual interest and intention in the educational environment, incidental facilities, and reviews. In conclusion, to equip the constituent parts of education program with entire propriety and an effective running system, information on breeding size and breeding career for managers in Hanwoo Industry with respect to age and academic career had to be clearly premeditated. It also needed the educational program to look at it from the standpoint of the managers.

Background: To investigate abnormal cervical histopathology (ACH) from hysterectomy specimens with normal preoperative Papanicolaou (Pap) smears. Materials and Methods: Medical records from May 2009 to April 2012 were retrospectively reviewed of subjects from whom hysterectomy specimens were taken in Thammasat University Hospital. All had normal preoperative Pap smears. ACH was the primary outcome. A p-value less than 0.05 was considered significant. A total of 483 subjects with an average age of 50.5 years were recruited. Benign cases of enlarged uterus and pelvic mass were present in 94% (430/483). Endometrial and ovarian cancer were found at 6.2 and 4.7%, respectively. In hysterectomy specimens there were 19 (4%) cases of ACH. Silent ACH with benign disease, endometrial and ovarian cancers were 1.2% (5/430), 33.3% (10/30) and 17.4% (4/23), respectively. The negative predictive value (NPV) and false negative rate of Pap smears were 96 and 4%, respectively. ACH in malignant cases were 27.9% (12/43) and 20% (2/10) in adequate (APS) and inadequate (IPS) Pap collection groups, respectively. ACH in benign condition were 0.68% (2/292) and 2.2% (3/138) in APS and IPS, respectively. ACH was more often found in hysterectomy specimens with indication of malignancy than benign conditions with statistical significance. One third of preoperative stage I endometrial cancer cases had cervical involvement. Conclusions: Silent ACH in normal preoperative Pap smear was 4 %. Inadequate Pap smear collection is still the major problem in this study. Reducing inadequate Pap smear collection could reduce the false negative rate.

We report a rare complication of iatrogenic spinal intradural following minimally invasive extradural endoscopic procedues in the lumbo-sacral spines. To our knowledge, intradural cyst following epiduroscopy has not been reported in the literature. A 65-year-old woman with back pain related with previous lumbar disc surgery underwent endoscopic epidural neuroplasty and nerve block, but her back pain much aggravated after this procedure. Postoperative magnetic resonance imaging revealed a large intradural cyst from S1-2 to L2-3 displacing the nerve roots anteriorly. On T1 and T2-weighted image, the signal within the cyst had the same intensity as cerebrospinal fluid. The patient underwent partial laminectomy of L5 and intradural exploration, and fenestration of the cystic wall was accomplished. During operation, the communication between the cyst and subarachnoid space was not identified, and the content of the cyst was the same as that of cerebrospinal fluid. Postoperatively, the pain attenuated immediately. Incidental durotomy which occurred during advancing the endoscope through epidural space may be the cause of formation of the intradural cyst. Intrdural cyst should be considered, if a patient complains of new symptoms such as aggravation of back pain after epiduroscopy. Surgical treatment, simple fenestration of the cyst may lead to improved outcome. All the procedures using epiduroscopy should be performed with caution.
