Wide, complex defects of the scalp caused by various insults always represent reconstructive challenges for surgeons. Our study group consisted of 18 patients (14 males and 4 females) with a mean age of 40.2 years. Nineteen free-tissue transfers were used to reconstruct the scalp defects. The selected cases included 8 latissimus dorsi muscle flaps, 3 latissimus dorsi myocutaneous flaps, 2 rectus abdominis muscle flaps, 3 omental flaps, 1 scapular flap, 1 radial forearm flap, and 1 groin flap. Tw

The preferential tax policies for foreign direct investment (FDI) in China were terminated by a tax reform in 2008. This article uses the provincial-level panel data for 1998‒2008 before the reform in order to study whether the tax incentive had been a significant determinant of foreign investment decisions. We find that market size and geographic location had significant impacts on the FDI inflow into China but the tax incentive policies were not a sufficient determinant of FDI inflow into Chin

We explore how the informational frictions underlying monetary exchange affect international exchange rate dynamics. Our perfectly flexible price model is capable of producing endogenously rigid international relative prices in response to technology and monetary shocks. The model is capable of accounting for the empirical regularities that the real and nominal exchange rates are more volatile than U.S. output, and that the two are positively and perfectly correlated. The model is also consisten

The reconstruction of large skeletal defects secondary to osteomyelitis is a challenging problem. This paper reports on the treatment of bone defects caused by osteomyelitis of the radius using an Ilizarov distraction technique and a vascularized fibular graft. A 25-year-old man first presented with a right radial defect caused by osteomyelitis when he was 3 years old. His right forearm was shortened and angulated with a dislocation of the distal radio-ulnar joint. The defect in the radial shaft

본 연구는 노인의 가족관계, 삶의 만족도, 우울의 정도를 파악하고, 가족관계와 삶의 만족도의 관계에서 우울의 매개효과를 검증하였다. 본 연구는 2012년 한국복지패널(KOWEPS) 7차년도의 원자료를 사용하여 2차 분석을 하였다. 배우자와 자녀가 2명 이상 있는 65세 이상의 노인들을 대상으로 구조방정식 모형분석을 실시하였다. 분석결과는 다음과 같다. 첫째, 노인의 가족관계가 좋을수록 우울수준은 낮고, 삶의 만족도는 높은 관계가 나타났으며, 우울수준이 낮을수록 삶의 만족도는 높은 관계가 나타났다. 둘째, 노인의 가족관계와 삶의 만족도의 관계에서 우울의 매개효과를 검증한 결과, 우울은 노인의 가족관계가 삶의 만족도에 미치는 영향을 매개하는 효과가 있는 것으로 나타났다. 연구결과를 근거로 노인의 가족관계 증진을 통해 우울을 예방하고 삶의 만족도를 높일 수 있는 실천적 및 정책적 함의를 제시하였다.

This paper aims to investigate impacts of public provision of universal health insurance (UHI) in an environment with household heterogeneity and financial market incompleteness. Various UHI polices with both distortionary and nondistortionary financing methods are compared to address the trade-off between risk reduction and tax distortion, as well as the corresponding welfare implications. We use a dynamic equilibrium model with endogenous insurance choice and labor supply decisions to perform

Abstract We study the economic fluctuations in China by using a standard neoclassical general equilibrium model to provide a structural analysis. We have carefully constructed measurements for economic variables from Chinese data to be consistent with the literature. We show that the government spending behaviour plays an important role in accounting for the changes in the pattern of both absolute and relative volatilities. Although we find that a general moderation in economic fluctuations afte

Many types of upper lip reconstruction have been introduced to treat defects after a tumor excision or trauma. The authors treated two cases of upper lip defects. A 35-year-old woman presented with a squamous cell carcinoma of the left upper lip that had invaded the corner of the mouth. After resecting the tumor, the defect was 3.7×3.5 cm in size. A 52-year-old woman presented with a dog bite of the right upper lip. The defect measured 4.0×2.2 cm in size. The two cases were reconstructed by comb

We report three new records Korean marine gastropods. The new record species are Hipponix acuta, Lyncina (Ponda) carneola, and Velutina (Velutella) plicatilis cryptospira. As a result, the family Hipponicidae in Korea turned out to be 5 species of 4 genera, Cypraeidae are 14 species of 8 genera, and Velutinidae are 7 species of 3 genera, respectively.

Up until now, we have identified 17 exotic species of Mollusca in Korea. These include Achatina (Lissachatina) fulica, Limax flavus, Limax marginatus, Deroceras reticulatum, Hawaiia minuscula, Zonitoides yessoensis, Zonitoides arboreus, Physa acuta, Pomacea canaliculata, Pomacea insularus, Crepidula (Crepidula) onyx, Mytilus galloprovincialis, Xenotrobus securis, Perna viridis, Argopecten irradians irradians, Pinctada fucata, and Pinctada margaritifera. Among them Achatina (Lissachatina) fulica,

한국 연안에 서식하는 둥근전복속 2종 및 2아종 (Nordotis madaka, N. gigantea, N. discus discus, N. discus hannai) 에 대한 형태학적 기재와 검색표를 제시하였고, 몇몇 혼용되어 사용된 우리말 이름을 정리하여 제언하였다. These studies describe about genus Nordotis (Nordotis madaka, N. gigantea, N. discus discus, N. discus hannai) and suggest the taxonomic key. Also, adjustment and suggestion that confused Korean names in the Nordotis species from Korea.

This study investigates the relationship between market power, as measured by aggregate markups, and income inequality across 34 countries between 1991 and 2016. We find that market power is positively associated with income inequality in developing countries, while the relationship between markups and income inequality in advanced economies is more nuanced and statistically insignificant. Our study reveals that a higher collective bargaining rights mitigate the impact of market power on income
