본 논문은 국산 배와 일본산 배에 대한 국내소비자의 무차별 선호를 가정한 가격격차 방법론을 적용하여 일본산 배의 수입금지 조치 해제 시 경제적 · 정량적 영향을 사전에 분석하는 방법론을 소개한다. 방법론을 이용하여 2018년 일본산 배의 수입허용 가정 시 시뮬레이션을 수행한 결과, 연평균 5만 톤의 일본산 배가 국내시장에 유입될 것으로 추정된다. 이 수입량은 국내 배 가격하락 뿐만 아니라 국산 배 생산량 감소를 야기하여 국내 배 생산 감소효과를 초래하여, 연평균 930억원 수준의 직접적인 피해가 예상된다. 국내 배 재배면적과 생산량은 베이스라인 대비 0.7%, 1.4% 감소할 것으로 예측된다. 또한, 생산 · 소비 대체재를 포함한 다른 품목 부문에 미치는 간접적인 영향을 합한 전체 농업분야의 연평균 감소액은 약 2,090억 원 수준으로 베이스라인 대비 0.4% 감소할 것으로 전망된다. 본 연구에서 제안한 SPS 수입금지 조치 해제 시나리오 영향평가는 기존에 수행해오던 양허안 중심의 시나리오 분석과 병행하여, 메가 FTA 참여 시 농업분야 파급영향의 사전분석 방법론을 개선할 것으로 기대된다. This paper proposed a methodology to analyze the economic and quantitative effects of lifting the import ban on Japanese pears by applying a price gap approach in the absence of any preference for either type of pear. Assuming that Korea will allow Japanese pear imports in 2018, the simulation results show that an annual average of 50,000 tons will flow into the domestic market from Japan. These imports will cause a decrease in the price and production of domestic pears, which would have a direct effect on the domestic pear industry, leading to an annual average reduction of 93 billion won. The cultivation area and production quantity are projected to be decreased by 0.7% and 1.4%, respectively, compared to the baseline. Also, the annual average reduction in the overall agriculture sector is predicted to be about 209 billion won, which is a 0.4% reduction compared to the baseline. This research is expected to improve the methodologies available for proactive analysis, with the existing analysis focused on customs tariffs when Korea considers joining mega-FTAs.

Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) of the thyroid gland is a very rare carcinoma. We herein report on a case of SMECE with metastasis to bilateral lateral neck nodes, esophagus, and trachea. A 72-year-old woman presented with a neck mass found incidentally during a medical check-up. She had a history of cerebral stroke without sequelae 20 years ago and was taking aspirin regularly. The neck mass was confirmed as papillary thyroid carcinoma by fine needle aspiration biopsy. The patient underwent bilateral total thyroidectomy with central compartment and bilateral compartment lateral neck dissection. The right recurrent laryngeal nerve was sacrificed due to tumor invasion. The trachea wall and esophagus were also invaded by the cancer. Histologically, the tumor showed dense fibrohyaline stroma and a goblet cell, nested islands of squamoid cells, and marked stromal eosinophilia with perineural invasion and lymphovascular invasion, confirming the diagnosis of SMECE. After radiation therapy for three months, distant metastasis to the liver, lung, and bone were found on PET-CT. This case appears to be more aggressive than previously reported cases.

Background/Aims: The aim of this study was to analyze the clinical impacts of obesity and hazardous alcohol use on the outcome of entecavir (ETV) therapy in chronic hepatitis B (CHB) patients. Methods: The medical records of 88 treatment-naive patients who were diagnosed with CHB and received ETV between March 2007 and September 2009 were analyzed retrospectively. Body mass index (BMI) values and Alcohol Use Disorders Identifi cation Test (AUDIT) scores were obtained at 6 months after the initiation of ETV (0.5 mg daily) treatment. Results: A BMI of 25 kg/m2 or more was recognized as an indicator of obesity, and a total AUDIT score of 8 or more was recognized as an indicator of hazardous alcohol use. Of the cohort, 24 patients (27.3%) were obese and 17 (19.3%) were hazardous alcohol users. The rate of seroconversion, alanine aminotransferase (ALT) normalization, and hepatitis B virus (HBV)-DNA negativity (<300 copies/mL) at 3, 6, and 12 months of treatment did not differ significantly between the normal-BMI and high-BMI groups. Moreover, the rate of seroconversion and HBV-DNA negativity at 3, 6, and 12 months of treatment did not diff er signifi cantly between the nonhazardous and hazardous alcohol users. However, the frequency of ALT normalization at 12 months was signifi cantly lower among hazardous alcohol users (91.5% vs. 70.6%; P=0.033). Conclusions: Obesity and hazardous alcohol drinking have no significant impact on the outcome of ETV treatment. However, the ALT normalization rate at 12 months after initiation of ETV treatment was signifi cantly lower among the hazardous alcohol users. (Clin Mol Hepatol 2012;18:195-202)

배경/목적 : 경추골동맥 기시부의 동맥경화증은 경추기저 국소빈혈증의 위험인자 중 하나이기 때문에 경추 골동맥 기시부를 확인해야 할 필요가 있다. 색도플러 초음파검사에 의한 경추골동맥 기시부의 관찰 및 평가는 기술적으로 어려움이 있으며, 특히 왼쪽 기시부는 더욱 그렇다. 이 연구의 목적은 색도플러 초음파검사 시경추골동맥 기시부의 관찰률을 높이는 것이다. 대상 및 방법 : 경동맥을 포함한 경추골동맥의 색도플러 초음파검사가 198명에 대해 시행되었다. 경추골동맥 기시부를 다른 혈관의 기시부와 더 쉽게 구분하기 위해 목 윗부분의 경추동맥에서부터 쇄골하동맥 측으로 검사를 시행하였다. 검사 기술적으로 경추골동맥 기시부가 바로누운자세의 자연스러운 위치에서 관찰되지 않을 경우, 초음파 트랜스듀서를 쇄골 측으로 밀고, 그래도 관찰되지 않을 경우 다른 손으로 어깨를 밀어 관찰을 시도하였다. 경추골동맥 기시부의 깊이와 위 세 가지 방법 및 그에 따른 관찰률을 확인하기 위하여, 검사된 초음파 영상에서 관찰된 경추골동맥 기시부의 위치를 3.0 cm 이하와 그 이상으로 구분하였다. 결 과 : 오른쪽 경추골동맥 기시부는 97%, 왼쪽 경추골동맥 기시부는 92%에서 관찰되었다. 3.0 cm 이하 에서 관찰된 오른쪽 경추골동맥 기시부 중 자연스러운 자세, 트랜스듀서 밀기, 그리고 어깨 밀기에서 관찰된 경우는 각각 98.6%, 1.4%, 그리고 0.0%이었다. 그리고 3.0 cm 보다 더 깊은 위치에서 관찰된 오른쪽 경추골동맥 기시부 중 자연스러운 자세, 트랜스듀서 밀기, 그리고 어깨 밀기에서 관찰된 경우는 각각 81.2%, 14.6%, 그리고 4.2%이었다. 3.0 cm 이하에서 관찰된 왼쪽쪽 경추골동맥 기시부 중 자연스러운 자세, 트랜스듀서 밀기, 그리고 어깨 밀기에서 관찰된 경우는 각각 85.4%, 10.7%, 그리고 3.9%%이었다. 그리고 3.0 cm 보다 더 깊은 위치에서 관찰된 오른쪽 경추골동맥 기시부 중 자연스러운 자세, 트랜스듀서 밀기, 그리고 어깨 밀기에서 관찰된 경우는 각각 55.7%, 30.4%, 그리고 13.9%이었다. 결 론 : 경추골동맥의 색도플러 초음파검사에서 그 기시부가 바로누운자세의 자연스러운 위치에서 관찰되지 않을 경우, 초음파 트랜스듀서를 쇄골 측으로 밀거나 그래도 관찰되지 않을 경우 다른 손으로 어깨를 밀어 관찰을 시도한다면, 관찰률을 좀더 높일 수 있을 것으로 사료된다. Background/aim : Atherosclerotic disease at the origin of the vertebral arteries is one of the risk factors for vertebrobasilar ischemic disease. Assessment and visualization of the origin of the vertebral arteries with color doppler sonography is a non-trivial task. The aim of this study is to increase the visualization rate of the origin of the vertebral arteries with color doppler sonography. Materials and Methods : Color doppler sonography for the vertebral arteries in cluded carotid arteries was performed to 198 patients. We first examined the vertebral artery in the upper neck in the direction of the subclavian artery to distinguish its origin more easily. If the vertebral artery origin was not visualized in natural position, the examiner pushed the transducer toward a clavicle or pushed the shoulder of patient by the other hand. The technical methods for visualization of the vertebral artery origin were classified into three grades: natural position, pushing the transducer, and pushing the shoulder of patient according to the depth (3.0 cm and shallower, deeper than 3.0 cm) of the origin. Results : The origin of the vertebral arteries could be visualized in 97% on the right and in 92% on the left. The origin of the vertebral arteries could be visualized in 98.6%, 1.4%, and 0.0% in natural position, pushing the transducer, and pushing the shoulder of patient, respectively, at shallower than 3.0 cm on the right side. The origin of the vertebral arteries could be visualized in 81.2%, 14.6%, and 4.2% in natural position, pushing the transducer, and pushing the shoulder of patient, respectively, at deeper than 3.0 cm on the right side. The origin of the vertebral arteries could be visualized in 85.4%, 10.7%, and 3.9% in natural position, pushing the transducer, and pushing the shoulder of patient, respectively, at shallower than 3.0 cm on the left side. The origin of the vertebral arteries could be visualized in 55.7%, 30.4%, and 13.9% in natural position, pushing the transducer, and pushing the shoulder of patient, respectively, at deeper than 3.0 cm on the left side. Conclusion : If the examiner pushes the transducer toward a clavicle or pushes the shoulder of patient by the other hand, when the vertebral artery origin during the color doppler sonography is not visualized in natural position, visualization rate of the origin of the both vertebral arteries is increased.

High electromechanical strain properties by the existence of nonergodicity in LiNbO₃–modified Bi_1/2Na_1/2TiO₃–SrTiO₃ relaxor ceramics

Hong, Young-Hwan,Han, Hyoung-Su,Jeong, Gwang-Hwi,Park, Young-Seok,Dinh, Thi Hinh,Ahn, Chang Won,Lee, Jae-Shin Elsevier 2018 CERAMICS INTERNATIONAL Vol.44 No.17

<P><B>Abstract</B></P> <P>This study investigated the effect of LiNbO<SUB>3</SUB> modification on the dielectric, ferroelectric and electromechanical strain properties of Bi<SUB>1/2</SUB>Na<SUB>1/2</SUB>TiO<SUB>3</SUB>–SrTiO<SUB>3</SUB> (BNT–ST) lead–free relaxor ceramics. The sintering temperature for lead–free BNT–ST relaxor ceramics was slightly decreased from 1175 °C to 1050 °C by modifying with LiNbO<SUB>3</SUB>. We found that the sintering temperature affects the dielectric behavior of 0.76BNT–(0.24−<I>x</I>)ST–<I>x</I>LiNbO<SUB>3</SUB> (BNST–100<I>x</I>LN) ceramics at high temperature (near dielectric maximum temperature, <I>T</I> <SUB>m</SUB>). The <I>T</I> <SUB>m</SUB> for the low–temperature sintered sample was shifted to relatively higher temperature by comparison with the high–temperature sintered samples. Furthermore, the degradation of dielectric behavior near <I>T</I> <SUB>m</SUB> in low–temperature sintered BNST–2LN ceramics was revealed after poling treatment and seem to be related to the existence of a high temperature stabilized nonergodic relaxor phase. Accordingly, we assume that the stabilized nonergodic relaxor phase is responsible for the relatively late transition from ferroelectrics to the relaxor. Therefore, we obtained the improved <I>d</I> <SUB>33</SUB> <SUP>*</SUP> of 616 pm/V as the highest value in low–temperature sintered BNST–2LN ceramics.</P>
