Bilateral Chylothorax Following Modified Radical Neck Dissection in Thyroid Cancer: A Case Report

송영백,이재건,최지우,소의영 대한갑상선-내분비외과학회 2014 The Koreran journal of Endocrine Surgery Vol.14 No.3

Bilateral chylothoraxis an extremely rare complication of modified radical neck dissection. It is a potentially life-threatening condition that can lead to severe respiratory, nutritional, metabolic, and immunologic disorders. Use of a multi-disciplinary approach including drainage of chyle, reduction of chyle formation, adequate nutritional support, use of somatostatin or its analogue, surgical ligation of the thoracic duct, and thoracic duct embolization is the best method for treatment of bilateral chylothorax. We report on a case of bilateral chylothorax following total thyroidectomy with modified radical neck dissection and discuss its management.

Objectives : This study was designed to investigate anti-obesity effects of DF in a ob/ob mouse model. Methods : Fifteen-week-old ob/ob mice were divided into four groups: a normal lean group given a standard diet, an ob/ob control group given a standard diet, and DF(1) and DF(2) groups given a standard diet with DF(1) (300 mg/kg), and DF(2) (600 mg/kg), respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : Body weight gain and fat mass were significantly decreased in DF(1) and DF(2) groups compared with control. The extent of decreases was eminent in DF(2) group. Feeding efficiency ratio were significantly decreased in DF(2) group compared with control. Consistent with their effects on body weight gain and fat mass, circulating concentrations of LDL, total cholesterol, free fatty acid, and insulin were decreased in DF(2) group compared with control. The size of adipocytes were significantly decreased by DF(2) compared with control. Consistent with their effects on body weight gain, hepatic lipid accumulation and liver weights were reduced in DF compared with control. Conclusions : In conclusion, these results suggest that DF not only decrease feeding efficiency ratio, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF also inhibits hepatic lipid accumulation.

칠레 아옌데 정권과 베네수엘라 차베스 정권의 국유화 정책과 이에 대한 미국의 재정적, 기술적 대응에 관한 연구

송영복(Song, Young-Bok),김도희(Kim, Do-Hee),김태경(Kim, Tae-Kyeong),백온유(Baek, On-Yoo) 한국외국어대학교 중남미연구소 2020 중남미연구 Vol.39 No.2

미국은 칠레의 아옌데 정권과 베네수엘라 차베스 정권의 기간산업 국유화 정책에 따른 다양한 압박정책을 시행하였다. 미국은 재정적 측면에서 두 국가에 대한 재정지원을 중단하거나, 미국 금융 시장 접근을 어렵게 하는 자체적 조치를 내렸다. 더 나아가, 국제 금융기구나 미국계 기업을 통한 직간접적 개입을 통해 두 국가의 경제적, 산업적 고립을 유도하였다. 한편, 칠레는 구리산업에 필요한 주요 부품과 예비 부품 조달에서, 베네수엘라는 석유의 생산과 정제과정에서 미국에 크게 의존하고 있었다. 미국은 산업에 대한 자체적 장비 및 기술이 부족했던 두 국가의 상황을 파악하고, 이에 개입하였다. 따라서 이를 통해 아옌데 시절의 칠레 구리산업이나 현 정권하의 베네수엘라 석유산업의 퇴조 원인에 미국의 압박정책이 큰 역할을 담당하고 있다는 것을 알 수 있다. The United States has implemented various pressure policies in accordance with Chile’s Allende and Venezuela’s Chavez regimes’ nationalization policies. In financial terms, the United States suspended funding the two countries or had taken measures to make it difficult for the two countries to access the United States financial market. Furthermore, through international financial institutions and American companies’ interventions, the United States induced the two countries to an economic and industrial isolation. Meanwhile, Chile and Venezuelan heavily relied on the United States in the procurement of major and spare parts in the copper industry and in process of production and refinement in the oil industry respectively. The United States identified and intervened in the situation of the two countries that lacked their own industrial equipment and technology. Therefore, it can be seen that the United States’ pressure policies played a large role in the cause of the declined Chilean copper industry during the Allende era and the Venezuelan oil industry under the current regime.

Fe-20%Mn 마르텐사이트 합금의 기계적 성질에 미치는 변형량 및 변형속도의 영향

김원백,최종술,박홍래,송영범 대한금속재료학회(대한금속학회) 1995 대한금속·재료학회지 Vol.33 No.9

The effects of compressive strain and strain rate on the strain-induced martensitic transformation and mechanical properties of Fe-20%Mn alloy were investigated. At low strain rates of 2×10^(-3)/sec and 2x10^(-1)/sec, the amounts of ε and α′ martensite increased with strain at the expense of γ. The increase was the largest at low strains up to 8%. At the highest strain rate of 6x10³/sec, the amount of retained γ increased due probably to the stabilization of γ by adiabatic heating during testing. The alloy showed high strain hardening especially in low strain range where most of the strain induced transformation occurred. The strain rate did not have an effect on strength when strain rates were low. When the strain rate increased to 6×10³/sec, the true stress increased at all strain levels. However, high strain rate did not increase the hardness. It seems that during a dynamic compression test an additional strengthening mechanism may work to increase the true stress. We believe that the dislocation drag effect may be responsible far the increase in stress during the high-rate compression test.

영상검지기 교정주기 설정방안

이청원,백남철,송영화,장진환 대한교통학회 2005 大韓交通學會誌 Vol.23 No.5

The accuracy of a video image detector(VID) is gradually reduced due to the various environmental and mechanical factors. But there has been no systematic research about this VID accuracy decreasing. To maintain a proper level of VID accuracy for the advanced traffic management, a regular VID calibration process needs to be introduced. Because of its cost, however, the calibration cannot be performed frequently. Therefore, the method to decide the optimal calibration interval should be studied in details. This study presents two different calibration interval decision methods. Using the invented data collection equipment, some data in the field were collected and analyzed, which were used for the adaptability checking. Although the data were limited, the result is pretty promising. More data needs to be investigated later and this study will help to maintain the data quality of the ITS center. 각종 환경적, 기술적 요인으로 인하여 영상검지기는 사용연한에 따라 정확도는 감소하기 마련인데 변화정도에 대해서 체계적으로 연구된 바가 없다. 영상검지기의 정확도를 적정수준으로 유지하기 위해서는 교정작업이 필수적이지만 예산적, 제도적 문제로 인해 엄밀한 교정이 실시되지 못해 양질의 교통관리에 제약으로 작용하고 있다. 본 연구는 실제 현장에서 쓰이고 있는 영상검지기들을 대상으로 정확도 검사방안을 개발하였고, 현장 조사를 통해 수집된 자료를 기반으로 최적 교정주기 설정방안을 개발하였다. 이는 정보의 질을 중시하는 ITS센터의 유지관리업무와 연계하여 정책적으로도 활용될 수 있을 것이다.

Central Lymph Node Metastasis Is an Important Prognostic Factor in Patients with Papillary Thyroid Microcarcinoma

이정훈,송영백,소의영 대한의학회 2014 Journal of Korean medical science Vol.29 No.1

Papillary thyroid microcarcinoma (PTMC) has been increasing, without a consensus for the management of this condition. In the present study, we analyzed the clinicopathological features of patients with PTMC to examine the impact of initial therapy and establish appropriate treatment. A total of 2,018 patients with PTMC were enrolled at a single university hospital. Of them, 1,245 patients (61.8%) underwent total thyroidectomy, and 1,838 patients (91.3%) underwent central lymph node (LN) dissection. Five-and 10-yr recurrence rates were 3.2% and 4.6%, respectively. In univariate analysis, the prognostic factors for recurrence were N stage, the number of LN metastases, and extrathyroidal extension. However, multivariate analysis revealed LN metastases and N stage as the only significant prognostic factors after adjusting for confounding factors (P<0.001). Additionally, multivariate analysis of a subgroup consisting of PTMC patients without N1b revealed the number of central LN metastases as the only significant factor. Therefore, intraoperative examination for central LN metastasis may discriminate high or low risk group.

Bacteremia due to Rahnella aquatilis in a Patient with a Chemoport

이우주,송영백,박상영,김미정 대한감염학회 2019 Infection and Chemotherapy Vol.51 No.2

Rahnella aquatilis, a saprophytic organism, is a member of the Enterobacteriaceae family. The natural habitat of this organism is fresh water, and it is rarely found in clinical specimens. Clinical conditions ascribed to this organism include bacteremia, respiratory infection, urinary tract infection, wound infection in an immunocompromised host, and infective endocarditis in patients with congenital heart diseases. Here, we report a case of bacteremia due to R. aquatilis in a woman with breast cancer who had received chemotherapy through a chemoport. To our knowledge, this is the second case of bacteremia caused by this organism in a patient with cancer in Korea.
