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.

Last target of architectural acoustics is that people wish to convey voice effectively from the space adaptively in use purpose in building. But, how exactly through space sound (sound source) that wish to deliver from indoor can be passed method to do quantification and evaluate quantity of sound by method to serve indoor architectural acoustics estimation summer period and methods to estimate definition propose. This Study searches special quality of sound source about MLS signal that is occurred short-answer sound source (pistol sound source) and nondirectional speaker among indoor sound estimation method, and measure and analyzed reverberation time (RT60), definition (C80, D50) by regulation of each ISO 3382 in age place (classroom, hall, gymnasium). Analysis result and sound factor among could know that d of two sound sources converges in measurement error extent about reverberation time (RT60) of analysis incidental and sound factors and value shows change irregularly about sound factor of D50, C80, pistol sound source judged there is problem. Also, could know that problem is happened in deflection except reverberation time is in deflection analysis with wave that measure each in fixed distance in branch. Finally, when differ size of sound source and measure about change of sound pressure level in case measure sound pressure level giving difference about 10 dB, sound factor could know that there is no different effect.

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.

동물원에서 사육 중이던 7세령 암컷 일본원숭이가 짝짓기 과정에서 피부에 외상을 입은 후 치료 도중 폐사하였다. 부검시 간에서 $1.3\times1.2\times1.0cm$ 크기를 비롯한 다양한 크기의 다발성 낭포가 관찰되었으며 낭포내에 점액성 액체가 저류되어 있었다. 현미경 소견상 낭포는 담관 상피세포로 덮혀 있었고 입방상피에서 원주상피까지 다양하였으며 대부분 단층이었으나 일부는 여러층으로 덮혀 있었다. 악성도나 다른 장기로의 전이 소견은 찾을 수 없었다. 본 증례는 일본 원숭이에서 발견된 첫 번째 담관 낭샘종 증례이다.

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.

편측성 다낭성 신 이형성증과 폐의 선천성 낭성 선종양 기형은 각각 독립된 질환으로 배아 시기에 발생 과정의 문제로 생긴다고 알려져 있다. 폐의 선천성 낭성 선종양 기형에서 폐 외의 기형으로 신장 기형이 동반될 수 있으나 생존 가능성이 적어 사산아로 출생되는 경우가 많다. 저자들은 위장관염으로 입원한 21개월 남아에서 우연히 편측성 다낭성 신 이형성증을 발견했고, 이 과정에서 폐의 선천성 낭성 선종양 기형도 발견하였기에 보고하는 바이다.

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.
