Catamenial hemoptysis is a rare condition, characterized by recurrent hemoptysis associated with the presence of intrapulmonary or endobronchial endometrial tissue. Therapeutic strategies proposed for intrapulmonary endometriosis with catamenial hemoptysis consist of medical treatments and surgery. Bronchial artery embolization is a well-established modality in the management of massive or recurrent hemoptysis, but has seldom been used for the treatment of catamenial hemoptysis. We report a case of catamenial hemoptysis associated with pulmonary parenchymal endometriosis, which was successfully treated by a bronchial artery embolization.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of euvolemic hypo-osmotic hyponatremia. There are several etiologies of SIADH including neuroendocrine tumor, pulmonary disease, infection, trauma, and medications. Here, we report a case of SIADH asso-ciated with a schwannoma involving the mediastinum in a 75-year-old woman who presented with nausea, vomiting, and general weakness. Laboratory testing showed hypo-osmolar hyponatremia, with a serum sodium level of 102mmol/L, serum osmolality of 221mOsm/kg, urine osmolality of 382mOsm/ kg, urine sodium of 55 mmol/L, and plasma antidiuretic hormone (ADH) of 4.40 pg/mL. Chest computed tomography identified a 1.5-cm-sized solid enhancing nodule in the right lower paratracheal area. A biopsy specimen was obtai-ned by video-assisted thoracoscopic surgery, which was diagnosed on pat-hology as a schwannoma. The hyponatremia was completely resolved after schwannoma resection and plasma ADH level decreased from 4.40 pg/mL to 0.86 pg/mL. This case highlights the importance of suspecting and iden-tifying the underlying cause of SIADH when faced with refractory or recur-rent hyponatremia, and that on possibility is mediastinal schwannoma

This study focused on subjects` emotional responses to color combinations. Subjects in their 20s participated in the experiment. Four living room images were constructed using a computer graphic program. The rooms were two analogous color combinations (R-YR, PB-B), and two complementary color combinations of warm and cool colors (R-BG, PB-Y) using the IRI 120 Hue & Tones system. The images were presented through a 23-inch LED monitor. Subjects responded to the SD scales, which included Valence and Arousal responses. The major findings are as follows. 1) When comparing each of the color images by SD scale responses, the subjects felt the warmest, lightest, softest, and brightest when viewing the R-YR image. The subjects felt the heaviest, hardest, and most disliked when viewing the PB-Y image. They also felt the dullest when viewing the R-BG image. 2) On the valence scale, the subjects felt the most pleasant when viewing the PB-B image and the most unpleasant when viewing the PB-Y image. On the arousal scale, the responses of the subjects showed no significant differences when compared among all of the colored images.

수질오염총량관리를 비롯한 유역관리제도의 시행에 있어서, 농업비점오염에 대한 삭감계획을 합리적으로 반영하기 위해서는 농업지역의 유출특성과 삭감행위로 인한 변화, 특히 유역 규모에서의 영향을 적절히 예측할 수 있어야 한다. 특히 우리나라는 수도작으로 인해 논의 비점오염 기여율이 높은데, 외국에서 개발된 유역모델은 일반적으로 논의 특성을 반영하는데 한계가 있다. 따라서 본 연구에서는 기존 유역모델 기법의 논에 대한 표현의 한계를 개선하기 위해, HSPF의 토지이용별 모듈(PERLND)과 하천 모듈(RCHRES), 그리고 모듈 간 물질 전달 경로를 정의하는 네트워크를 적절히 재구성하여 논의 영농특성을 반영할 수 있는 Paddy-RCH기법을 개발하고, 실험논에 적용하여 보정 및 검증과정을 통해 적용성을 평가하였다. 물수지 관련, 담수심의 경우 3개의 실험논에서 %Diff. (%상대오차)가 -2.38 ~ -5.31% (Very Good), R<SUP>2</SUP>는 0.654 (Fair) ~ 0.892 (Very Good) 수준으로 평가되었고, 유출량의 경우 %Diff.가 -13.97 (Good) ~ -22.68% (Fair), R<SUP>2</SUP>는 0.778 (Good) ~ 0.837 (Very Good)으로 평가되었다. 한편, 수질예측에 있어서 %Diff.는 BOD가 -5.54 ~ 8.37% (Very Good), T-N은 -9.74 ~ 14.73% (Very Good), T-P는 2.62 (Very Good) ~ 17.95% (Good)으로 평가되었다. 이에 따라, 비록 한정된 기간 및 지역에서의 적용이지만, 각 논의 운영 상황을 반영하여 모의된 결과가 비교적 양호하게 실측치의 경향성을 표현할 수 있는 것으로 평가되었다. 이러한 방법은 누구나 제공받을 수 있는 모델을 활용하여, 영농방법에 따른 필지 및 유역규모의 영향을 동시에 파악할 수 있고, 기존 예측기법과 연계할 수 있다는 점에서 이점을 가질 수 있으며, 향후 논에서의 삭감효과와 유역에서의 수질개선 효과를 정량화하는데 활용 가능할 것으로 판단된다. In the implementation of the Total Pollution Load Control (TPLC), in order to reasonal consider the reduction-plan for agricultural non-point sources (agNPS), be properly predictable. In Korea, agNPS caused by paddy fields occupies a large proportion, but general watershed models have limitations in simulating the water-balance and water quality mechanisms from paddy fields. In this study, the HSPF Paddy-RCH method that can simulate mechanisms of paddy in the watershed model was developed by connecting the PERLND module and the RCHRES module, and reconstructing the mass transfer path between modules. And the applicability of Paddy-RCH methods was evaluated by simulation on test paddies. As a result of calibration and verification, water-depth (ΔS) was evaluated as Very-Good, and runoff was Good (-13.97%) ~ Fair (-22.68%). In the water-quality prediction, BOD and T-N were evaluated as Very-Good, and T-P was Very-Good (2.62%) ~ Good (17.95%). It was evaluated that simulated results can represent the tendency of the measured value relatively well. The paddy-RCH method can be advantageous in that it can simultaneously grasp the influence of paddy fields and watershed size according to farming methods, can link with existing prediction methods by using a model that can be provided to everyone.

블루투스 기술에 기반한 무선헤드폰 장치는 음악을 전송하는 송신장치가 근거리에 위치한 단일의 수신측 무선헤드폰 장치에 음악을 전송하는 단일링크 구조로 구성되어 있다. 음악 재생 서비스를 제공하기 위해서는 데이터 전송의 동시성과 연속성이 보장되어야 끊기지 않고 신뢰성이 보장된 서비스를 제공할 수 있다. 따라서 장치들 간의 링크구조가 1:1 단일 구조의 한계성을 가지게 된다. 본 논문에서는 단일의 송신장치가 두 개의 수신장치에 각각의 개별 링크를 설정하여 동일한 음악을 동시에 전송하기 위한 시스템의 구성 방법을 제안하였다. 제안한 방법에서는 시스템의 전송효율을 높이기 위하여 멀티 스레드 처리 기법을 사용하였으며, 블루투스스택 클래스를 구현하였다. 제안한 이중링크 음악전송 시스템의 전송효율을 분석하기 위한 데이터 전송 실험을 통하여 다중링크 음악 전송의 가능성을 확인하였다.

We have previously reported that live Bifidobacterium longum SPM1207, a strain isolated from healthy adult Koreans, significantly reduced serum cholesterol in broth and rat. We here examined the effect of oral administration of sonication-killed B. longum SPM1207 on serum cholesterol in rats in order to investigate whether this killed strain could be utilized as a potent probiotics for human and animals. Dietary treatments consisted of 3 treatment groups of 24 rats each randomly assigned to either normal diet, high cholesterol diet and saline (HCS), or high cholesterol diet and sonication-killed B. longum SPM1207 (HCKB) for 3 weeks. Although HDL-cholesterol levels in the serum were not significantly (p > 0.05) different between HCKB rats and HCS rats, total and LDL-cholesterol levels in the serum were significantly (p < 0.05) less increased in HCKB (total: 177.71 mg/dL, LDL-: 60.50 mg/dL) rats when compared to HCS (total: 237.17 mg/dL, LDL-: 71.50 mg/dL) rats. AI was significantly (p < 0.05) lower in HCKB (4.95 mg/dL) rats when compared to HCS (9.22 mg/dL) rats. Body weight increase and relative liver weight were significantly (p < 0.05) lower in HCKB rats when compared to HCS rats. Over the time, high cholesterol diet caused dry feces accompanied by decreased fecal water content (66.00 to 61.94%) but sonication-killed B. longum SPM1207administration increased fecal water content (71.58 to 74.25%). The results in the current study provide evidence that the sonication-killed cells of B. logum SPM1207 isolated from healthy adult Koreans have a greater potential to be used as a cholesterol-lowering agent. Furthermore, the current study suggest that this killed specific strain may play role in part in blocking the body weight increase and relieving or eliminating constipation.
