| 1 | Effect of an Artificial Caudal Fin on the Performance of a Biomimetic Fish Robot Propelled by Piezoelectric Actuators显示文摘This paper addresses the design of a biomimetic fish robot actuated by piezoceramic actuators and the effect of artificial caudal fins on the fish robot's performance. The limited bending displacement produced by a lightweight piezocomposite actuator was amplified and transformed into a large tail beat motion by means of a linkage system. Caudal fins that mimic the shape of a mackerel fin were fabricated for the purpose of examining the effect of caudal fin characteristics on thrust pro-duction at an operating frequency range. The thickness distribution of a real mackerel's fin was measured and used to design artificial caudal fins. The thrust performance of the biomimetic fish robot propelled by fins of various thicknesses was examined in terms of the Strouhal number,the Froude number,the Reynolds number,and the power consumption. For the same fin area and aspect ratio,an artificial caudal fin with a distributed thickness shows the best forward speed and the least power con-sumption. | Seok Heo Tedy Wiguna Hoon Cheol Park Nam Seo Goo | 2007 | Journal of Bionic Engineering2007，4，3： | 16 |

| 5 | Sandwich-structure transferable free-form OLEDs for wearable and disposable skin wound photomedicine显示文摘Free-form optoelectronic devices can provide hyper-connectivity over space and time.However,most conformable optoelectronic devices can only be fabricated on flat polymeric materials using low-temperature processes,limiting their application and forms.This paper presents free-form optoelectronic devices that are not dependent on the shape or material.For medical applications,the transferable OLED(10μm)is formed in a sandwich structure with an ultra-thin transferable barrier(4.8μm).The results showed that the fabricated sandwich-structure transferable OLED(STOLED)exhibit the same high-efficiency performance on cylindricalshaped materials and on materials such as textile and paper.Because the neutral axis is freely adjustable using the sandwich structure,the textile-based OLED achieved both folding reliability and washing reliability,as well as a long operating life(>150 h).When keratinocytes were irradiated with red STOLED light,cell proliferation and cell migration increased by 26 and 32%,respectively.In the skin equivalent model,the epidermis thickness was increased by 39%;additionally,in organ culture,not only was the skin area increased by 14%,but also,reepithelialization was highly induced.Based on the results,the STOLED is expected to be applicable in various wearable and disposable photomedical devices. | Yongmin Jeon Hye-Ryung Choi Jeong Hyun Kwon Seungyeop Choi Kyung Mi Nam Kyoung-Chan Park Kyung Cheol Choi | 2019 | Light(Science & Applications)2019，8，1： | 9 |
| 6 | Efficacy and safety of limited endoscopic sphincterotomy before self-expandable metal stent insertion for malignant biliary obstruction显示文摘AIM To evaluate the safety and efficacy of limited endoscopic sphincterotomy (ES) before placement of selfexpandable metal stent(SEMS).METHODS This was a retrospective analysis of 244 consecutive patients with unresectable malignant biliary obstruction, who underwent placement of SEMSs following limited ES from December 2008 to February 2015. The diagnosis of malignant biliary obstruction and assessment of patient eligibility for the study was established by a combination of clinical findings, laboratory investigations, imaging and pathological results. All patients were monitored in the hospital for at least 24 h following endoscopic retrograde cholangio pancreatography(ERCP). The incidence of immediate or early post-ERCP complications such as post-ERCP pancreatitis(PEP) and bleeding related to limited ES were considered as primary outcomes. Also, characteristics and complications according to the cancer type were classified.RESULTS Among the 244 patients included, the underlying diagnosis was cholangiocarcinoma in 118 patients,pancreatic cancer in 79, and non-pancreatic or nonbiliary malignancies in the remaining 47 patients. Early post-ERCP complications occurred in 9 patients(3.7%), with PEP in 7 patients (2.9%; mild, 6; moderate, 1) and mild bleeding in 2 patients (0.8%). There was no significant association between the incidence of post-ERCP complications and the type of malignancy(cholangiocarcinoma vs pancreatic cancer vs others, P = 0.696) or the type of SEMS used (uncovered vs covered, P = 1.000). Patients who had more than one SEMS placed at the first instance were at a significantly higher risk of post-ERCP complications (one SEMS vs two SEMS, P = 0.031). No other factors were predictive of post-ERCP complications.CONCLUSION Limited ES is feasible and safe, and effectively facilitates the placement of SEMS, without any significant risk of PEP or severe bleeding. | Hyeong Seok Nam Dae Hwan Kang Hyung Wook Kim Cheol Woong Choi Su Bum Park Su Jin Kim Dae Gon Ryu | 2017 | World Journal of Gastroenterology2017，23，9： | 7 |
| 7 | Is endoscopic ultrasonography essential for endoscopic resection of small rectal neuroendocrine tumors?显示文摘AIM To evaluate the importance of endoscopic ultrasonography(EUS) for small(≤ 10 mm) rectal neuroendocrine tumor(NET) treatment.METHODS Patients in whom rectal NETs were diagnosed by endoscopic resection(ER) at the Pusan National University Yangsan Hospital between 2008 and 2014 were included in this study. A total of 120 small rectal NETs in 118 patients were included in this study. Histologic features and clinical outcomes were analyzed, and the findings of endoscopy, EUS and histology were compared. RESULTS The size measured by endoscopy was not significantly different from that measured by EUS and histology(r = 0.914 and r = 0.727 respectively). Accuracy for the depth of invasion was 92.5% with EUS. No patients showed invasion of the muscularis propria or metastasis to the regional lymph nodes. All rectal NETswere classified as grade 1 and demonstrated an L-cell phenotype. Mean follow-up duration was 407.54 ± 374.16 d. No patients had local or distant metastasis during the follow-up periods. CONCLUSION EUS is not essential for ER in the patient with small rectal NETs because of the prominent morphology and benign behavior. | Su Bum Park Dong Jun Kim Hyung Wook Kim Cheol Woong Choi Dae Hwan Kang Su Jin Kim Hyeong Seok Nam | 2017 | World Journal of Gastroenterology2017，23，11： | 7 |
| 8 | Improvement of Artificial Foldable Wing Models by Mimicking the Unfolding/Folding Mechanism of a Beetle Hind Wing显示文摘In an attempt to realize a flapping wing micro-air vehicle with morphing wings, we report on improvements to our previousfoldable artificial hind wing.Multiple hinges, which were implemented to mimic the bending zone of a beetle hind wing, weremade of small composite hinge plates and tiny aluminum rivets.The buck-tails of rivets were flared after the hinge plates wereassembled with the rivets so that the folding/unfolding motions could be completed in less time, and the straight shape of theartificial hind wing could be maintained after fabrication.Folding and unfolding actions were triggered by electrically-activatedShape Memory Alloy (SMA) wires.For wing folding, the actuation characteristics of the SMA wire actuator were modifiedthrough heat treatment.Through a series of flapping tests, we confirmed that the artificial wings did not fold back and arbitrarilyfluctuate during the flapping motion. | Azhar Muhammad Quoc Viet Nguyen Hoon Cheol Park Do Y.Hwang Doyoung Byun Nam Seo Goo | 2010 | Journal of Bionic Engineering2010，7，2： | 6 |

| 12 | Free radical scavenger effect of rebamipide in sperm processing and cryopreservation显示文摘Alm:To study the effect of rebamipide added to semen samples and cryoprotectant on reactive oxygen species (ROS) production. Methods: Semen samples from 30 fertile and healthy volunteers were collected bymasturbation after 2 days-3 days of abstinence. After liquefaction, the specimens were diluted with sperm washmedia to a uniform density of 20×10^6/mL. Rebamipide was added to semen samples and cryoprotectant to a final concentration of 10μmol/L, 30μmol/L, 100μmol/L or 300μmol/L. Specimens were incubated at 37℃ in a 0.5 % CO2 incubator for I h or cryopreserved at -196℃ LN2 for 3 days. The sperm motility and viability and the levels of ROS and lipid peroxidation of sperm membrance were assessed before and after incubation and cryopreservation by means of computer assisted semen analyzer, eosin-nigrosin stain, chemiluminescence and thiobarbituric acid assay,respectively. Results: The sperm motility was significantly increased after incubation with 100 gmol/L and 300gmol/L rebamipide (P<0.05). After cryopreservation, the sperm motility was significantly decreased in all concentra-tions (P<0.05), but the decrease was less with 100μmol/L and 300μmol/L rebamipide than that with otherconcentrations. The sperm viability showed no significant difference before and after incubation (P>0.05). The levels of ROS and lipid peroxidation in semen were significantly decreased in proportion to the concentrations of rebamipide both after incubation and cryopreservation (P<0.05). Conclusion: Rebamipide is an effective flee radical scavenger in semen in vitro.

| 13 | Effects of Korean Red Ginseng on Semen Parameters in Male Infertility Patients:A Randomized,Placebo-Controlled,Double-Blind Clinical Study显示文摘Objective: To investigate the effects of Korean red ginseng(KRG) on semen parameters in male infertility patients in a randomized, double-blind, placebo-controlled study. Methods: A total of 80 male infertility patients with varicocele were recruited from April 2011 to February 2012. The subjects were then divided into the following four groups: non-varicocelectomy(V)+placebo(P) group, V+P group, non-V+KRG group(1.5-g KRG daily), and V+KGR group(1.5-g KRG daily). Semen analysis was performed and hormonal levels were measured in each treatment arm after 12 weeks. Results: All groups but not the non-V+P group, showed significant improvements in sperm concentrations, motility, morphology, and viability at the end of the study. However, there were no significant differences in serum follicle-stimulating hormone, luteinizing hormone, and testosterone among groups. The incidence of adverse events was low, and all events were assumed to be unrelated to the treatments administered. Conclusions: Although the exact mechanism by which KRG improves spermatogenesis remains unclear, KRG may be a useful agent for the treatment of male infertility. Nevertheless, additional studies to evaluate the optimal dose and duration of treatment are needed. | Hyun Jun Park Sangmin Choe Nam Cheol Park | 2016 | Chinese Journal of Integrative Medicine2016，22，7： | 4 |
| 14 | The Role of Elytra in Beetle Flight: Ⅰ.Generation of Quasi-Static Aerodynamic Forces显示文摘We conducted a comprehensive study to investigate the aerodynamic characteristics and force generation of the elytra of abeetle,Allomyrina dichotoma.Our analysis included wind tunnel experiments and three-dimensional computational fluiddynamics simulations using ANSYS-CFX software.Our first approach was a quasi-static study that considered the effect ofinduced flapping flow due to the flapping motion of the fore-wings (elytra) at a frequency of around 30 Hz to 40 Hz.The dihedralangle was varied to represent flapping motion during the upstroke and downstroke.We found that an elytron producespositive lift at 0° geometric angle of attack,negative lift during the upstroke,and always produces drag during both the upstrokeand downstroke.We also found that the lift coefficient of an elytron does not drop even at a very high geometric angle of attack.For a beetle with a body weight of 5 g,based on the quasi-static method,the fore-wings (elytra) can produce lift of less than 1%of its body weight. | Patar Ebenezer Sitorus Hoon Cheol Park Doyoung Byun Nam Seo Goo Cheol Heui Han | 2010 | Journal of Bionic Engineering2010，7，4： | 4 |
| 15 | Advantage of endoscopic mucosal resection with a cap for rectal neuroendocrine tumors显示文摘AIM: To compare the outcomes of endoscopic mucosal resection with a cap(EMR-C) with those of endoscopic submucosal dissection(ESD) for the resection of rectal neuroendocrine tumors.METHODS: One hundred and sixteen lesions in 114 patients with rectal neuroendocrine tumor(NET) resected with EMR-C or ESD were included in the study. This study was performed at Pusan National University Yangsan Hospital between July 2009 and August 2014. We analyzed endoscopic complete resection rate,pathologic complete resection rate,procedure time,and adverse events in the EMR-C(n = 65) and ESD(n = 51) groups. We also performed a subgroup analysis by tumor size.RESULTS: Mean tumor size was 4.62 ± 1.66 mm in the EMR-C group and 7.73 ± 3.14 mm in the ESD group(P < 0.001). Endoscopic complete resection rate was 100% in both groups. Histologic complete resection rate was significantly greater in the EMR-C group(92.3%) than in the ESD group(78.4%)(P = 0.042). Mean procedure time was significantly longer in the ESD group(14.43 ± 7.26 min) than in the EMR-C group(3.83 ± 1.17 min)(P < 0.001). Rates of histologic complete resection without complication were similar for tumor diameter ≤ 5 mm(EMR-C,96%; ESD,100%,P = 0.472) as well as in cases of 5 mm < tumor diameter ≤ 10 mm(EMR-C,80%; ESD,71.0%,P = 0.524).CONCLUSION: EMR-C may be simple,faster,and more effective than ESD in removing rectal NETs and may be preferable for resection of small rectal NETs. | Su Bum Park Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Su Jin Kim Hyeong Seok Nam | 2015 | World Journal of Gastroenterology2015，21，31： | 4 |
| 16 | Use of a Digital Image Correlation Technique for Measuring the Material Properties of Beetle Wing显示文摘Beetle wings are very specialized flight organs consisting of the veins and membranes.Therefore it is necessary from abionic view to investigate the material properties of a beetle wing experimentally.In the present study,we have used a DigitalImage Correlation (DIC) technique to measure the elastic modulus of a beetle wing membrane.Specimens were prepared bycarefully cutting a beetle hind wing into 3.0 mm by 7.0 mm segments (the gage length was 5 mm).We used a scanning electronmicroscope for a precise measurement of the thickness of the beetle wing membrane.The specimen was attached to a designedfixture to induce a uniform displacement by means of a micromanipulator.We used an ARAMISTM system based on the digitalimage correlation technique to measure the corresponding displacement of a specimen.The thickness of the beetle wing variedat different points of the membrane.The elastic modulus differed in relation to the membrane arrangement showing a structuralanisotropy;the elastic modulus in the chordwise direction is approximately 2.65 GPa,which is three times larger than the elasticmodulus in the spanwise direction of 0.84 GPa.As a result,the digital image correlation-based ARAMIS system was suc-cessfully used to measure the elastic modulus of a beetle wing.In addition to membrane’s elastic modulus,we considered thePoisson’s ratio of the membrane and measured the elastic modulus of a vein using an Instron universal tensile machine.Theresult reveals the Poisson’s ratio is nearly zero and the elastic modulus of a vein is about 11 GPa. | Tailie Jin Nam Seo Goo Sung-Choong Woo Hoon Cheol Park | 2009 | Journal of Bionic Engineering2009，6，3： | 4 |

| 19 | Assessment of disease activity by fecal immunochemical test in ulcerative colitis显示文摘AIM To evaluate the efficacy of quantitative fecal immunochemical test(FIT) as biomarker of disease activity in ulcerative colitis(UC).METHODS Between February 2013 and November 2014, a total of 82 FIT results, obtained in conjunction with colonoscopies, were retrospectivelyevaluated for 63 patients with UC. The efficacy of FIT for evaluation of disease activity was compared to colonoscopic findings. Quantitative fecal blood with automated equipment examined from collected feces. Endoscopic disease severity were assessed using the Mayo endoscopic subscore(MES) classification. The extent of disease were classified by proctitis(E1), left sided colitis(E2), and extensive colitis(E3). Clinical activity were subgrouped by remission or active.RESULTS All of 21 patients with MES 0 had negative FIT(< 7 ng/mL), but 22 patients with MES 2 or 3 had a mean FIT of > 134.89 ng/m L. The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and accuracy of negative FIT about mucosal healing were 73.33%, 81.82%, 91.49%, 51.43% and 73.17%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of predictive value of positive FIT(cutoff value > 100 ng/mL) about active disease status were 45.45%, 93.33%, 71.43%, 82.35%and 26.83%, respectively. Among patients with clinical remission, FIT was negative in 31(81.6%) of 38 cases, with a mean fecal hemoglobin concentration of 6.12 ng/mL(range, negative to 80.9 ng/mL) for this group of patients. Among patients with clinical active disease, FIT was negative in 16(36.4%) out of 44 cases, with a mean fecal hemoglobin concentration > 167.4 ng/mL for this group of patients. FIT was positively correlated with endoscopic activity(r = 0.626, P < 0.01) and clinical activity(r = 0.496, P < 0.01). But, FIT did not correlate with the extent of disease(r =-0.047, P = 0.676)CONCLUSION Quantitative FIT can be a non-invasive and effective biomarker for evaluation of clinical and endoscopic activity in UC, but not predict the extent of disease. | Dae Gon Ryu Hyung Wook Kim Su Bum Park Dae Hwan Kang Cheol Woong Choi Su Jin Kim Hyeong Seok Nam | 2016 | World Journal of Gastroenterology2016，22，48： | 3 |
