World Journal of Gastroenterology 2011年第14期17卷 1874-1878页

作者： Hee-jin Kwon Myong-jin Kang jin-Han cho Jong-Young Oh Kyung-jin Nam Sang-Yeong Han Sung Wook Lee Department of Radiology Dong-A University HospitalDongdaesindong 3gaSeo-guPusan 602-715South Korea Department of Internal Medicine Dong-A University HospitalDongdaesindong 3gaSeo-guPusan 602-715South Korea

AIM:To evaluate the potential usefulness of acoustic radiation force impulse (ARFI) images for evaluation of hepatocellular carcinomas (HCC)-associated radiofrequency ablation. METHODS:From January 2010 to June 2010,a total of 38 patients with HCC including recurred HCCs after RFA underwent ARFI elastography. The brightness of tumor was checked and the shear wave velocity was measure-d for the-quantification of stiffne-ss. According to theb-rightne-ss,the-tumors we-re-classifie-d as b-righte-r,samecolor and darker compared with adjacent parenchyma. Using the same methods,8 patients with recurred HCCs after RFA state were evaluated about the brightness compared with adjacent RFA ablation area. RESULTS:In the 38 patients with HCCs,20 (52.6%)were brighter than surrounding cirrhotic parenchyma. Another 13 (34.2%) were darker. The others (5 cases,13.2%) were seen as the same color as the adjacent liver parenchyma. Post-RFA lesions were darker than previous tumor and surrounding parenchyma in all 38 cases. However,recurred HCCs were brighter than the treated site in all 8 cases. CONCLUSION:Using ARFI technique is helpful for differential diagnosis in order to detect recurred HCCs more easily in patients with confusing status.

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第9期7卷 1467-1473页

作者： SHIN Bong-cheol KIM Gun-hee choI jin-hwa JEON Byung-cheol LEE Honghee cho Myeong-woo HAN jin-yong PARK Dong-sam Division of Mechanical Engineering Inha University Incheon 402-751 Korea Department of Mechanical Engineering University of Incheon Incheon 402-749 Korea

Recently, with the rapid growth of information technology, many studies have been performed to implement Web-based manufacturing system. Such technologies are expected to meet the need of many manufacturing industries who want to adopt E-manufacturing system for the construction of globalization, agility, and digitalization to cope with the rapid changing market requirements. In this research, a real-time Web-based machine tool and machining process monitoring system is developed as the first step for implementing E-manufacturing system. In this system, the current variations of the main spindle and feeding motors are measured using hall sensors. And the relationship between the cutting force and the spindle motor RMS (Root Mean Square) current at various spindle rotational speeds is obtained. Thermocouples are used to measure temperature variations of important heat sources of a machine tool. Also, a rule-based expert system is applied in order to decide the machining process and machine tool are in normal conditions. Finally, the effectiveness of the developed system is verified through a series of experiments.

Calcium and Calmodulin-Mediated Regulation of Gene Expression in Plants

引用

Molecular Plant 2009年第1期2卷 13-21页

作者： Min Chul Kim Woo Sik Chung Dae-jin Yun Moo Je cho Division of Applied Life Science (BK21 Program) Plant Molecular Biology and Biotechnology Research Center and Environmental Biotechnology National Core Research Center Gyeongsang National University Jinju 660-701 Korea

Sessile plants have developed a very delicate system to sense diverse kinds of endogenous developmental cues and exogenous environmental stimuli by using a simple Ca^2＋ ion. Calmodulin （CAM） is the predominant Ca^2＋ sensor and plays a crucial role in decoding the Ca^2＋ signatures into proper cellular responses in various cellular compartments in eukaryotes. A growing body of evidence points to the importance of Ca^2＋ and CaM in the regulation of the transcriptional process during plant responses to endogenous and exogenous stimuli. Here, we review recent progress in the identification of transcriptional regulators modulated by Ca^2＋ and CaM and in the assessment of their functional significance during plant signal transduction in response to biotic and abiotic stresses and developmental cues.

Exercise improves the effects of testosterone replacement therapy and the durability of response after cessation of treatment： a pilot randomized controlled trial

引用

Asian Journal of Andrology 2017年第5期19卷 602-607页

作者： Dae-Yeon cho Jeong Kyun Yeo Seung Ik cho Jae Eun Jung Sang jin Yang Doo hwan Kong Jeong Ku Ha jin Goo Kim Min Gu Park Inje University Sanggye Paik Hospital Department of Urology Seoul Korea Inje University Seoul Paik Hospital Department of Urology Seoul Korea KonKuk University Medical Center Department of Orthopedics Seoul Korea Inje University Seoul Paik Hospital Department of Orthopedics Sports Medical Center Seoul Korea

The effects of the combination of exercise and TRT on symptoms of late-onset hypogonadism （LOH） and the durability of response after cessation of TRT were investigated. A total of fifty patients with erectile dysfunction （ED） who had a sedentary lifestyle and low serum total testosterone （T） levels were enrolled and followed for 20 weeks. Patients were randomly divided into two groups; all of them received T gel for 12 weeks and it was discontinued for 8 weeks. Patients assigned to Group II were offered a supervised exercise program for 20 weeks. Measurement of serological testing was performed and self-assessment questionnaires and Global Assessment Question （GAQ） were asked. Baseline characteristics and the initial symptom scores showed no significant difference between the two groups. Serum total T levels and the symptom scores were increased at 12 weeks in both groups, and Group II showed better results with statistical significance. There was a decrease in T levels and worsening of symptom scores at week 20 compared to week 12 in both groups, and Group II showed better results with statistical significance. On the GAQ, Group II showed higher ratio of ＂yes＂ at week 12 and the same tendency was sustained at week 20 with significant difference between two groups. The combination of exercise and TRT showed significant improvements in serum T levels and LOH symptoms compared to TRT alone. In addition, these improvements were maintained in the combination group with continuous exercise, even after cessation of TRT.

Measuring nasolacrimal duct volume using computed tomography images in nasolacrimal duct obstruction patients in Korean

引用

International Journal of Ophthalmology(English edition) 2019年第1期12卷 100-105页

作者： jin-hwan Park Jung-Ah Huh Jun-Feng Piao hwa Lee Se-Hyun Baek Department of Ophthalmology Korea University College of Medicine

AIM: To investigate nasolacrimal duct(NLD) volume in Korean patients and to examine the correlation between NLD volume and obstruction. METHODS: Of patients who underwent orbital computed tomography from March 2013 to January 2016, patients diagnosed with NLD obstruction were classified into the patient group and patients without obstruction were classified into the control group. The NLD volume was measured using the Image J program, which showed the NLD in axial,coronal, and sagittal images on computed tomography. RESULTS: The average value of men's NLD volume,265.33±90.57 mm3, was significantly larger than women's,211.87±68.61 mm3(P=0.009). In the patient group, the NLD volume of the obstructed eyes, 242.49±82.93 mm3,and the non-obstructed eyes, 225.20±73.20 mm3, were significantly higher than the control group, 217.61±82.04 mm3(P<0.001, P<0.001). CONCLUSION: The NLD volume is larger in men than in women in Korean adults. If there is NLD obstruction in women, the NLD volume is larger and it is judged that inflammatory reaction caused a chronic change in the bone around the NLD and affect the measurement of NLD volume.
