Bertolotti's syndrome (BS) is a disease that should be differentiated from low back pain (LBP) in young patients. BS shows an anatomical abnormality in which elongated transverse processes of the last lumbar vertebra articulate or fuse with varying degrees to the sacrum or ilium according to radiologic findings, which is associated with the clinical feature of LBP or radiating pain. In this case report, we describe various clinical features such as a waddling gait with severe foot and triceps surae muscle pain, in addition to the typical symptom of BS such as LBP. We report the various clinical symptoms and treatment progress in this case and review the literature.

This paper proposes a novel automated liver segmentation using Multi-Dilated U-Nets. The proposed multidilation segmentation model has the advantage of considering both local and global shapes of the liver image. We use the CT images subject-wise, every 2D image is concatenated to 3D to calculate the IOU score and DICE score. The experimental results on Jeonbuk National University hospital dataset achieves better performance than the conventional U-Net.

Synthesis of novel 9-fluoroanthracyclines carrying L-fucose as a sugar component is described. Compound 3 containing a fluorine at the C-9 position was synthesized from an epoxide 2 and HF/Pyr (7 : 3). Bromination and hydrolysis of compound 3 resulted in synthesis of an aglycone, 9-fluoroanthracyclinone 6. The α-(1b) and β -anomers (1a) of the final product were obtained in high yields by a coupling reaction with the L-fucose.

한약재 및 식품으로의 개발가능성이 높지만 현재 멸종 위험에까지 처해있는 천문동의 체계적 보호 및 보존을 위하여 수집된 유전자원의 유전 유연관계 분석을 실시한 결과는 다음과 같다. 1. 수집된 자생 천문동 23종에 대한 RAPD분석을 실시한 결과 primer 당 평균 8.5개의 PCR 밴드가 얻어졌으며 polymorphism 비율이 $42.9{\sim}91.7%$ 이었으며 평균 72.9%를 나타내어 객관적 다형 현상 분석이 가능하였다. 2. 유사도 0.82를 기준으로 23개의 천문동 수집종을 구분한 결과 6개의 group으로 분리되었는데 group I 은 전남 여수의 은적암, 경남 남해 이동, 전북 부안 위도, 전남 진도 지산과 전북 부안 하서종 이었고 Group II는 전남 영광 송이도와 전북 부안 계화. 전북 고창 아산 2, 전북 군산 개야도(적경종), 전북 고창 아산 1 그리고 일본 자생종 이었으며 group III는 전남 여수의 향일암, 충남 보령 남포, 전북 군산 선유도 1, 전북 군산 선유도 2, 전북 군산 오식도, 충남 서천 서면 자생종, Group IV는 경남 사천종과 전북 군산 선유도 2 적경종이었고 Group V는 전북 익산 금마 자생종과 중국 호남성의 적경종, Group IV는 중국종(청경종)과 군산 개야도 자생종(청경종)으로 각각 나뉘어겼다. 3. BLOTTO 사용에 의한 효율적 유연관계 분석에서는 BLOTTO를 사용할 경우 PCR 효율이 향상되어 band 획득수가 증가하고 좀더 선명한 PCR 산물의 획득이 가능하였으며 적절한 사용농도는 1% 이었다.

We investigated the effects of Al and Mg on the microstructure and hardness of the coating layer of galvanized steel sheets, by thermodynamic calculations, X-ray diffraction, scanning electron microscopy, and Vickers hardness tests of Zn-0.2Al, Zn-6Al-2Mg, and Zn-10Al-5Mg coating layers. Regardless of the alloy composition of the galvanizing bath, a Fe-Al layer was observed between the coating layer and steel sheet. The Zn-0.2Al coating layer consists of major h.c.p. Zn phase and minor f.c.c. Al phase. The fraction of f.c.c. Al phase (containing a significant amount of Zn) of the coating layer increases with increasing the chemical composition of Al of the galvanizing bath. The h.c.p. MgZn₂ phase was formed in the Al/Mg-containing Zn-6Al-2Mg and Zn-10Al-5Mg coating layers, forming Zn-Al-MgZn₂ eutectic microstructure. The primary MgZn₂ phase was additionally formed in the Zn-10Al-5Mg coating layers containing high concentrations of Al and Mg. The Vickers hardness values of Zn-0.2Al, Zn-6Al-2Mg, and Zn-10Al-5Mg coating layers were 59.1 ± 1.2 HV, 161.2 ± 5.7 HV, and 215.5 ± 40.3 HV, respectively. The addition of Al and Mg increased the hardness of the coating layer by increasing the fraction of the Al phase (containing Zn) and MgZn₂ intermetallic compound, which were harder than the Zn phase.

This study examined the effects of plated temperature on the surface morphology and property of an electrodeposited copper foil. The morphology, crystal structure and electric characteristics of the electrodeposited copper foil were examined by scanning electron microscopy, X-ray diffraction, and a four-point probe, respectively. The surface roughness, crystal growth orientation and resistivity could be controlled using various temperature of electrolyte. Large particles were observed on the surface of the copper layer electroplated onto the $30^{\circ}C$. However, a uniform surface, lower resistivity and high flexibility were obtained when a $50^{\circ}C$ electrolyte was used.

A typical trade-off relationship exists between strength and elongation in face-centered cubic metals. Studies have recently been conducted to enhance strength without ductility reduction through surface-treatment-based ultrasonic nanocrystalline surface modification (UNSM), which creates a gradient microstructure in which grains become smaller from the inside to the surface. The transformation-induced plasticity effect in Fe-Mn alloys results in excellent strength and ductility due to their high work-hardening rate. This rate is achieved through strain-induced martensitic transformation when an alloy is plastically deformed. In this study, Fe-6%Mn powders with different sizes were prepared by high-energy ball milling and sintered through spark plasma sintering to produce Fe-6%Mn samples. A gradient microstructure was obtained by stacking the different-sized powders to achieve similar effects as those derived from UNSM. A compressive test was performed to investigate the mechanical properties, including the yielding behavior. The deformed microstructure was observed through electron backscatter diffraction to determine the effects of gradient plastic deformation.

대한결핵협회 12개 시ㆍ도지부 산하에는 총9곳의 복십자의원이 있다. 전북지부 복십자의원도 바로 그 중 하나. 대한결핵협회 전북지부는 타지역에 비해 비교적 늦은 1958년 창설되었고, 1983년 부설 복십자의원이 문을 열면서 비로소 지금의 형태를 갖추게 되었다.
