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.

Seok-Hong Park,Dong-Yub Kim,Won-Jae Lee,Min Jang,Seong Mok Jeong,Sae-Kwang Ku,Young-Sam Kwon,Sungho Yun The Korean Society of Veterinary Science 2024 Journal of Veterinary Science Vol.25 No.2

Background: Achilles tendon is composed of dense connective tissue and is one of the largest tendons in the body. In veterinary medicine, acute ruptures are associated with impact injury or sharp trauma. Healing of the ruptured tendon is challenging because of poor blood and nerve supply as well as the residual cell population. Platelet-rich plasma (PRP) contains numerous bioactive agents and growth factors and has been utilized to promote healing in bone, soft tissue, and tendons. Objective: The purpose of this study was to evaluate the healing effect of PRP injected into the surrounding fascia of the Achilles tendon after allograft in rabbits. Methods: Donor rabbits (n = 8) were anesthetized and 16 lateral gastrocnemius tendons were fully transected bilaterally. Transected tendons were decellularized and stored at -80℃ prior to allograft. The allograft was placed on the partially transected medial gastrocnemius tendon in the left hindlimb of 16 rabbits. The allograft PRP group (n = 8) had 0.3 mL of PRP administered in the tendon and the allograft control group (n = 8) did not receive any treatment. After 8 weeks, rabbits were euthanatized and allograft tendons were transected for macroscopic, biomechanical, and histological assessment. Results: The allograft PRP group exhibited superior macroscopic assessment scores, greater tensile strength, and a histologically enhanced healing process compared to those in the allograft control group. Conclusions: Our results suggest administration of PRP on an allograft tendon has a positive effect on the healing process in a ruptured Achilles tendon.

Empirical Analysis on Causation among Service FDI, Service Trade and Economic Growth: Evidence form Korea

Won-Seok Choi,Seung-Lin Hong 한국무역연구원 2018 貿易 硏究 Vol.14 No.6

The Korean economy has shifted from the manufacturing industry to the service industry since the early 2000s. The purpose of this study is to analyze the causal relationships among trade, foreign direct investment, and economic growth in these transformed industrial structures. We applied the Vector Autoregression (VAR) model to analyze the causality between these variables and to estimate the short-term and long-term effects. As a result, service FDI and service exports were found to have a unidirectional effect on economic growth. In the Impulse Response Function, service exports and service FDI were found to have a significant effect on economic growth and service imports. We also found that service exports and service foreign direct investment have a significant impact on economic growth and service imports, and are also important for both variables in their short-term and long-term effects based on the Impulse Response Function and Forecast Error Variance Decomposition. However, the effect of the two variables gradually decreased over time. Therefore, in order for the Korean economy to grow in a service-oriented economy, it is necessary to develop measures for qualitative growth rather than quantitative expansion of service in exports and FDI.

Transparent and Flexible Antenna for Wearable Glasses Applications

Hong, Seungman,Kang, Seok Hyon,Kim, Youngsung,Jung, Chang Won IEEE 2016 IEEE transactions on antennas and propagation Vol.64 No.7

<P>This paper aims to design, fabricate, and analyze transparent and flexible monopole antennas for an application in wearable glasses. A multilayer electrode film composed of 100-nm-thick indium-zinc-tin oxide (IZTO)/Ag/IZTO (IAI), a type of transparent conducting oxide electrodes, is selected as the conductors of antennas and ground planes of the wearable glasses. The average transparency of the proposed antennas is measured to be 81.1% in the visible wavelength, and the electrical conductivity of the proposed antennas is measured to be 2 000 000 S/m. The proposed antennas are fabricated with physical vapor deposition process in high vacuum. Moreover, non-transparent antennas made of a 40-nm-thick silver (Ag) thin film are designed and fabricated to compare their performances with the transparent IAI antennas. To reduce the electromagnetic field absorption of the human head, we introduced and analyzed three configurations (types A-C) of monopole antennas having different directions of radiation patterns. The fabricated IAI antennas show the average efficiency of 40% and 4-dBi peak gain at 2.4-2.5 GHz. Furthermore, they have a specific absorption rate lower than 1.6 W/kg, which complies with the Federal Communications Commission standard, when the input power is 15 dBm, which is Google Glass's.</P>

Clinical impacts of hazardous alcohol use and obesity on the outcome of entecavir therapy in treatment-naïve patients with chronic hepatitis B infection

Won Gil Chung,Hong Joo Kim,Young Gil Choe,Hyo Sun Seok,Chang Wook Chon,Yong Kyun Cho,Byung Ik Kim,Young Yool Koh 대한간학회 2012 Clinical and Molecular Hepatology(대한간학회지) Vol.18 No.2

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-naïve 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.
