| ○ | ○ | Article | Transversus abdominis plane block for lumboperitoneal shunt surgery in idiopathic normal pressure hydrocephalus: a case report | The transversus abdominis plane (TAP) block is an ideal pain control method used in surgeries that require abdominal wall incisions through the injection of an anesthetic solution into the plane between the internal oblique muscle and transversus abdominis muscle. Herein, we report an 83-year-old man who was diagnosed with idiopathic normal pressure hydrocephalus (iNPH) and underwent lumboperitoneal shunt surgery (LPS). The TAP block was performed before LPS, and the numerical rating scale for pain was 0 at day 1 after the surgery. The patient was discharged early at day 3 after surgery despite the patient being extremely old, as he reported quick relief from the postoperative abdominal pain. The TAP block can hence be considered for use before LPS in elderly patients with iNPH. | Cho, Jinduck; Yeo, Jinseok; Chang, Sung Hyun; Yoon, Sang-Youl; Park, Seong-Hyun; Kang, Kyunghun; Kim, Chi-Hun; Hahm, Myong Hun; Park, Eunhee; Park, Ki-Su | Kyungpook Natl Univ, Sch Med, Dept Anesthesia & Pain Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, 101 Dongin Dong 2 Ga, Daegu 700422, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ Med Ctr, Dept Phys & Rehabil Med, Daegu, South Korea | 22936861300; 35072322000; 57753019200; 57195615457; 21734563200; 55365592200; 56984274000; 56015548700; 56107216400; 55932363100 | kiss798@gmail.com; | JOURNAL OF SURGICAL CASE REPORTS | J SURG CASE REP | 2042-8812 | 4 | ESCI | SURGERY | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | desflurane; lidocaine; propofol; rocuronium; abdominal pain; abdominal wall; aged; anesthesia; Article; brain ventricle dilatation; case report; cerebrospinal fluid shunting; clinical article; fascia; fluoroscopy; gait disorder; general anesthesia; human; human tissue; iliac crest; male; normotensive hydrocephalus; nuclear magnetic resonance imaging; oblique internal abdominal muscle; subarachnoid space; transversus abdominis plane block; ultrasound; vertebral canal; very elderly; visual analog scale | English | 2021 | 2021-04 | 10.1093/jscr/rjab123 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Tunable high-temperature itinerant antiferromagnetism in a van der Waals magnet | Discovery of two dimensional (2D) magnets, showing intrinsic ferromagnetic (FM) or antiferromagnetic (AFM) orders, has accelerated development of novel 2D spintronics, in which all the key components are made of van der Waals (vdW) materials and their heterostructures. High-performing and energy-efficient spin functionalities have been proposed, often relying on current-driven manipulation and detection of the spin states. In this regard, metallic vdW magnets are expected to have several advantages over the widely-studied insulating counterparts, but have not been much explored due to the lack of suitable materials. Here, we report tunable itinerant ferro- and antiferromagnetism in Co-doped Fe4GeTe2 utilizing the vdW interlayer coupling, extremely sensitive to the material composition. This leads to high T-N antiferromagnetism of T-N similar to 226 K in a bulk and similar to 210 K in 8 nm-thick nanoflakes, together with tunable magnetic anisotropy. The resulting spin configurations and orientations are sensitively controlled by doping, magnetic field, and thickness, which are effectively read out by electrical conduction. These findings manifest strong merits of metallic vdW magnets as an active component of vdW spintronic applications. | Seo, Junho; An, Eun Su; Park, Taesu; Hwang, Soo-Yoon; Kim, Gi-Yeop; Song, Kyung; Noh, Woo-suk; Kim, J.

| ○ | ○ | Article | Two case reports of pneumatosis intestinalis in patients with cancer: is surgical management mandatory? | Pneumatosis intestinalis (PI) can be classified into two groups. Primary PI is idiopathic, and patients can recover spontaneously. In contrast, secondary PI is considered fatal due to the high mortality rate associated with mesenteric ischemia. Herein, we describe two patients with PI and concurrent pneumoperitoneum. Both patients were receiving targeted anticancer therapy, yet neither developed abdominal pain nor fatal symptoms. One of the patients underwent surgery, while the other was managed conservatively. Even though there were no complications, the patient who underwent surgery was hospitalized for 34 days, whereas the one who was managed conservatively was hospitalized for only five days. Usually, patients with cancer receiving chemotherapy are immunosuppressed and susceptible to infections. Therefore, based on the patients' clinical features, surgical management of patients with cancer who develop PI after receiving anticancer chemotherapy should be done prudently. | Yeo, In Hwan; Kim, Yun Jeong | Kyungpook Natl Univ, Dept Emergency Med, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Yeo, Inhwan/GXZ-7024-2022 | 57216816807; 57202340666 | kimyjem@knu.ac.kr; | CLINICAL AND EXPERIMENTAL EMERGENCY MEDICINE | CLIN EXP EMERG MED | 2383-4625 | 8 | 3 | ESCI | EMERGENCY MEDICINE | 2021 | N/A | 0.16 | 2025-07-30 | 2 | 1 | Pneumoperitoneum; Conservative treatment; Neoplasms; Pneumatosis cystoides intestinalis | NONSURGICAL CAUSES | Conservative treatment; Neoplasms; Pneumatosis cystoides intestinalis; Pneumoperitoneum | axitinib; C reactive protein; cabozantinib; creatinine; lactate dehydrogenase; methylprednisolone; nitrogen; abdominal distension; abdominal pain; abdominal radiography; adult; aged; antineoplastic activity; Article; cancer chemotherapy; cancer surgery; case report; chronic obstructive lung disease; clinical article; clinical feature; computer assisted tomography; disease exacerbation; dyspnea; echography; emergency ward; epigastric discomfort; follow up; hospitalization; human; hypothyroidism; immunosuppressive treatment; intestine perforation; liver function test; male; malignant neoplasm; mesenteric ischemia; middle aged; mortality rate; pneumatosis intestinalis; pneumoperitoneum; thorax pain; thorax radiography; urea nitrogen blood level; very elderly; x-ray computed tomography | English | 2021 | 2021-09 | 10.15441/ceem.20.153 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Two Cases of Tacrolimus-related Transplant-associated Thrombotic Microangiopathy Retinopathy after Allogenic Peripheral Blood Stem Cell Transplantation | Purpose: We report two cases of tacrolimus-related transplant-associated thrombotic microangiopathy (TA-TMA) retinopathy in leukemia patients who had undergone allogenic peripheral blood stem cell transplantation (PBSCT). Case summary: (Case 1) A 58-year-old woman with a history of PBSCT due to acute myelocytic leukemia and taking tacrolimus was referred to the ophthalmology clinic with visual disturbance. Her visual acuity (VA) was 0.4 in the right eye and 0.5 in the left eye. Multiple cotton wool spots and retinal hemorrhages were found in both eyes on fundus examination. Multiple capillary non-perfusions were seen on fluorescein angiography (FA). Tacrolimus-related TA-TMA retinopathy was suspected. Tacrolimus was discontinued and plasmapheresis was performed. After 3 months, neovascular glaucoma developed and her VA became "counting fingers" at 20 cm in both eyes. (Case 2) A 20-year-old man with a history of PBSCT due to acute lymphocytic leukemia and taking tacrolimus was referred to our clinic because of decreased VA in both eyes. His VA was 0.05 in the right eye and 0.025 in the left eye. Fundus and FA findings were the same as in Case 1, and the patient was suspected to have tacrolimus-related TA-TMA retinopathy. Tacrolimus was discontinued and plasmapheresis was performed. His VA was 0.2 in the right eye and 0.4 in the left eye at 1 month after treatment. Conclusions: It is necessary to consider TA-TMA retinopathy in leukemia patients taking calcineurin inhibitors, such as tacrolimus, who have decreased VA. Early diagnosis and treatment are important. | Lee, Seong Taik; Kim, Su Yeun; Kang, Yong Koo; Park, Han Sang; Park, Dong Ho; Shin, Jae Pil | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea | KANG, YONG KOO/IVH-8723-2023 | 57277512500; 57315991300; 57204703736; 57208186456; 36676632900; 56517350400 | jps11@hanmail.net; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 62 | 10 | ESCI | OPHTHALMOLOGY | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | Allogenic peripheral blood stem cell transplantation; Tacrolimus; Transplant-associated thrombotic microangiopathy | Allogenic peripheral blood stem cell transplantation; Tacrolimus; Transplant-associated thrombotic microangiopathy | Korean | 2021 | 2021-10 | 10.3341/jkos.2021.62.10.1428 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Two- and three-terminal HfO2-based multilevel resistive memories for neuromorphic analog synaptic elements | Synaptic elements based on memory devices play an important role in boosting neuromorphic system performance. Here, we show two types of fab-friendly HfO2 material-based resistive memories categorized by configuration and an operating principle for a suitable analog synaptic device aimed at inference and training of neural networks. Since the inference task is mainly related to the number of states from a recognition accuracy perspective, we first demonstrate multilevel cell (MLC) properties of compact two-terminal resistive random-access memory (RRAM). The resistance state can be finely subdivided into anMLC by precisely controlling the evolution of conductive filament constructed by the local movement of oxygen vacancies. Specifically, we investigate how the thickness of the HfO(2)(-)switching layer is related to anMLC, which is understood by performing physics-based modeling in MATLAB from a microscopic view. Meanwhile, synaptic devices driven by an interfacial switching mechanism instead of local filamentary dynamics are preferred for training accelerated neuromorphic systems, where the analogous transition of each state ensures high accuracy. Thus, we introduce three-terminal electrochemical random-access memory that facilitates mobile ions across the entire HfO2 switching area uniformly, resulting in highly controllable and gradually tuned current proportional to the amount of migrated ions. | Kang, Heebum; Park, Jinah; Lee, Dokyung; Kim, Hyun Wook; Jin, Sol; Ahn, Minjoon; Woo, Jiyong | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57232405900; 58299836300; 57961974700; 57557016000; 57796769200; 58299836400; 53985749100 | jiyong.woo@knu.ac.kr; | NEUROMORPHIC COMPUTING AND ENGINEERING | 2634-4386 | 1 | 2 | 0.77 | 2025-07-30 | 13 | 15 | neuromorphic computing; synaptic device; resistive switching memory; electrochemical random-access memory | ELECTRONIC SYNAPSE; SWITCHING MEMORY; DEVICES; RRAM | electrochemical random-access memory; neuromorphic computing; resistive switching memory; synaptic device | English | 2021 | 2021-12 | 10.1088/2634-4386/ac29ca | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Proceedings Paper | UAV Deployment with Flexible Height Under SINR Constraint | This paper proposes using UAVs as auxiliary flying relays between IoT access points (APs) and terrestrial base stations/satellites. Specifically, we consider the 3D deployment of multiple UAVs above a given area of APs, aiming at providing efficient services to the APs while optimizing the overall performance of UAVs. In particular, we aim to minimize the number of required UAV flights when serving the APs within a demanded time, which is constrained by the total available power of UAVs, and maximize the total number of successfully served APs. For this, we propose an integer linear programming (ILP) model that can achieve the above goals by adjusting the UAV hovering heights in the appropriately selected coordinates. The proposed ILP model is evaluated when considering interference among the multiple UAVs and compared with the schemes based on fixed heights. The numerical results show that the proposed ILP model can automatically adjust the flying height of UAVs to reduce the flights when complying with the constraints of the signal-to-interference-noise ratio (SINR) threshold and the number of APs to be served. | Zhao, Ke; Peng, Limei | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | 57439189700; 7201574271 | kezhao@knu.ac.kr;auroraplm@knu.ac.kr; | 2021 INTERNATIONAL CONFERENCE ON NETWORKING AND NETWORK APPLICATIONS, NANA | 0.37 | 2025-07-30 | 0 | 2 | SINR; UAV's deployment; UAV's altitude; relay | relay; SINR; UAV's altitude; UAV's deployment | Integer programming; Signal interference; Unmanned aerial vehicles (UAV); Access points; Available power; Integer linear programming models; Multiple UAVs; Numerical results; Performance; Relay; Signalto-interference noise ratios (SINR); UAV altitude; UAV deployment; Signal to noise ratio | English | 2021 | 2021 | 10.1109/nana53684.2021.00085 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Article | Ultrasonographic and clinical findings in cats with feline lower urinary tract disease | Urethral obstruction is a life-threatening feline lower urinary tract disease (FLUTD). The rate of recurring urethral obstruction was 14.8-58.1% after the first occurrence. Ultrasonographic findings associated with reobstruction had been rarely reported although ultrasonography was a valuable technique for diagnosing urinary bladder calculi and distinguishing different FLUTD causes. This retrospective study aims to describe the ultrasonographic findings, urinalysis, and serum chemistry profile in cats with FLUTD and determine the associations of reobstruction with ultrasonographic findings, urinalysis, and serum chemistry profile. The present study included 141 cats that were followed up for more than 1 year. The ultrasonographic criteria included the presence of cystolithiasis, urine echogenicity, sediment, suspended linear strand, pericystic effusion, hyperechoic pericystic fat, ureteral dilation, pyelectasia, and perirenal effusion. The urinalysis criteria included hematuria, urine-specific gravity, pH, sediment, and proteinuria. The most common ultrasonographic findings in cats with FLUTD were echogenic urine and sediment. However, this study did not find an association between reobstruction and ultrasonographic findings, urinalysis, and serum chemistry profiles. Thus, an ultrasonographic examination may be insufficient to predict the risk of reobstruction although it is a useful modality for diagnosing FLUTD and making treatment direction. © 2021, Korean Society of Veterinary Clinics.

| ○ | Article | Understanding the targeted metabolites and molecular structure of starch in Kimchi according to glutinous rice paste content during fermentation | This study identified and quantified the sugar-related metabolites and analyzed the structural features of starch in kimchi added with various concentrations of glutinous rice paste during fermentation. The pH values and total bacterial counts indicated that the fermentation of kimchi with 10% glutinous rice paste progressed more quickly than that of kimchi with other rice paste concentrations. The addition of glutinous rice pastes to kimchi resulted in increased glucose and decreased fructose contents during fermentation compared to the control kimchi. Maltose content increased significantly with increasing glutinous rice paste concentrations. The average chain length distribution of starch in kimchi decreased with increasing proportions of short chains as fermentation progressed. However, the average chain length distribution of starch increased with increasing glutinous rice paste concentration in kimchi. Our results confirmed that the sugar-related metabolites and starch structural changes were highly influenced by the added starch paste concentration. © 2021 Korean Society of Food Science and Technology.

| ○ | ○ | Article | Unusual Presentation of Anal Pain and Tenesmus from Rectal Arteriovenous Malformation Successfully Treated with Ethanol Sclerotherapy | Gastrointestinal arteriovenous malformation (AVM) is reported as one of the possible causes of intestinal bleeding, and its occurrence in the rectum is rare. We report the case of a rectal AVM patient who experienced uncommon symptoms of anal pain and tenesmus and was treated successfully with percutaneous transarterial ethanol sclerotherapy. The patient underwent routine colonoscopy with biopsy at the time of visit; however, an accurate diagnosis was difficult. Subsequent contrast-enhanced computed tomography (CT) and angiography revealed a rectal AVM emerging from the distal inferior mesenteric artery with engorged superior rectal veins. The feeding artery was catheterized, and concurrent transarterial sclerotherapy with 80% ethanol was performed. There was no major complication related to the procedure. Disappearance of AVM nidus and improvement of associated venous congestion were shown by follow-up CT. There was no recurrence of symptoms after 10 months of clinical observation. Transarterial ethanol sclerotherapy is safe and effective in treating rectal AVM and can be considered as one of the nonsurgical treatment options. (C) 2021 The Author(s) Published by S.

| ○ | Article | Updating Obstacle Information Using Object Detection in Street-View Images; [스트리트뷰 영상의 객체탐지를 활용한 보행 장애물 정보 갱신] | Street-view images, which are omnidirectional scenes centered on a specific location on the road, can provide various obstacle information for the pedestrians. Pedestrian network data for the navigation services should reflect the up-to-date obstacle information to ensure the mobility of pedestrians, including people with disabilities. In this study, the object detection model was trained for the bollard as a major obstacle in Seoul using street-view images and a deep learning algorithm. Also, a process for updating information about the presence and number of bollards as obstacle properties for the crosswalk node through spatial matching between the detected bollards and the pedestrian nodes was proposed. The missing crosswalk information can also be updated concurrently by the proposed process. The proposed approach is appropriate for crowdsourcing data as the model trained using the street-view images can be applied to photos taken with a smartphone while walking. Through additional training with various obstacles captured in the street-view images, it is expected to enable efficient information update about obstacles on the road. © 2021 Korean Society of Surveying.

| ○ | Article | Upsampling of 16-channel LiDAR depth data using weighted median filter | Three-dimensional (3D) LiDAR is widely used because it can accurately measure 360° 3D depth. One of the most widely used sensors to this end is VLP-16, a 16-channel LiDAR manufactured by Velodyne. This 16-channel LiDAR provides dense 3D depth data in the horizontal direction. However, in the vertical direction, it provides only sparse depth data owing to the LiDAR architecture. We propose an upsampling method to obtain a dense 3D depth map from a 16-channel LiDAR by applying an edge-aware filter to the LiDAR data. A camera-LiDAR sensor system composed of a 16-channel LiDAR and six vision cameras is used for this purpose. First, the LiDAR depth data are projected onto the camera image coordinates to generate a 2.5D depth map. Next, bilinear interpolation and a weighted median filter are applied to upsample the original depth map. Compared with the original LiDAR data, we can generate an extremely dense depth map by using the proposed method. The results of quantitative analysis show that the proposed method can dramatically increase the number of 3D depth points and reduce the depth reconstruction error. © ICROS 2021. | Lim, Hyun-Bin; Kim, Eung-Su; Lee, Duk-Man; Kim, Hee-Soo; Park, Soon-Yong | Gyeongbuk Institute of IT Convergence Industry Technology, South Korea; Koh Young Technology Incorporated, South Korea; Industry-Academic Cooperation Group, Kyungpook National University, South Korea; Industry-Academic Cooperation Group, Kyungpook National University, South Korea; School of Electronics Engineering, Kyungpook National University, South Korea | 57222133438; 57188702879; 57223985771; 57191880449; 7501834063 | sypark@knu.ac.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 27 | 5 | 0.32 | 2025-07-30 | 4 | Depth map; LiDAR; Robot vision; Upsampling; Weighted median filter | Agricultural robots; Cameras; Median filters; Signal sampling; Bilinear interpolation; Camera images; Dense depth map; Depth reconstruction; LIDAR sensors; Threedimensional (3-d); Vertical direction; Weighted median filter; Optical radar | Korean | Final | 2021 | 10.5302/j.icros.2021.21.0005 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Uptake and Carry-over of Procymidone Residues to Non-target Succeeding Crop from Applied on Preceding Crop | BACKGROUND: Pesticides can persist in soil due to multiannual uses. To decrease the concerns for potential carry-over of such residues from treated soil during preceding crop cultivation to non-target crops grown in rotation, an uptake study of procymidone was conducted under the actual cultivation conditions in Korea. METHODS AND RESULTS: Procymidone was sprayed twice by foliar application with recommended and double dose according to the safe use guidelines for Korean cabbage up to 14 days before harvest. Arable land was kept fallow for 4 days after harvesting Korean cabbage, and spinach was cultivated as a succeeding crop. Initial residues in soil were 5.670-14.175 mg/kg that were degraded to 3.098-4.555 mg/kg until harvest of Korean cabbage, and then persisted at 1.026-1.300 mg/kg by spinach harvest. Procymidone residues in edible part of succeeding crops from soil uptake were in range of 0.020-0.048 mg/kg for recommended dose and 0.055-0.116 mg/kg for double dose. Root concentration factor (RCF) values of procymidone at different concentration ranged from 0.053 to 0.123, and translocation factor (TF) ranged from 0.176 to 0.768 for spinach. The value of TF was higher than RCF, indicating that the capability of translocation to shoot was relatively higher than that of root uptake and accumulation. CONCLUSION: Procymidone applied on Korean cabbage can be carried-over to spinach and detected at a level similar to MRL (0.05T mg/kg). Therefore, this study suggests a follow-up study for establishment of plant back interval (PBI) of succeeding crops reflecting the actual agricultural conditions as this study. © 2021 The Korean Society of Environmental Agriculture. | Kwak, Se-Yeon; Lee, Sang-Hyeob; Sarker, Aniruddha; Kim, Hyo-Young; Shin, Byung-Gon; Kim, Jang-Eok | Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea; Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea; Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea; Safety Analysis Division, Experiment Research Institute, National Agricultural Products Quality Management Service, Kimcheon, 39660, South Korea; Safety Analysis Division, Experiment Research Institute, National Agricultural Products Quality Management Service, Kimcheon, 39660, South Korea; Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea | 57202752311; 57202747805; 57211874397; 57224535109; 59882223800; 7601387161 | jekim@knu.ac.kr; | Korean Journal of Environmental Agriculture | 1225-3537 | 40 | 3 | 0.31 | 2025-07-30 | 4 | Carry-Over; Preceding Crop; Procymidone; Succeeding Crop; Uptake | Korean | Final | 2021 | 10.5338/kjea.2021.40.3.24 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Uptake and Translocation of Ethoprophos Mixed with Soil for Cultivation of Preceding Crop into Succeeding Crop | BACKGROUND: Unintentional residual pesticide in soil derived from preceding crops and the transfer to succeeding crops was considered a critical barrier for positive list system (PLS). Thus, an uncertain risk is predicted for etho-prophos applied at cultivation of preceding crop (Korean cabbage) to succeeding crop (spinach). METHODS AND RESULTS: Ethoprophos was treated on soil following the recommended dose and 5 times dose according to the safe use guidelines for Korean cabbage after seeding. On the 4 days after harvesting of preceding crop, spinach was sowed. The initial residual amounts of ethoprophos on soil (7.081-19.493 mg/kg) were decreased to 3.832-7.218 mg/kg until the harvest of Korean cabbage, and then finally decreased to 0.011-0.079 mg/kg after spinach cultivation. The uptake rates of ethoprophos from soil by Korean cabbage were 0.01-0.03% and distributed to root (0.150-0.903 mg/kg) and shoot (0.021-0.151 mg/kg), respectively. The residual amounts of uptake and trans-location from preceding crop cultivated soil to spinach edible part were found to be below LOQ. CONCLUSION: The plant back internal (PBI) for ethopro-phos is not recommended during sequential cultivation of leafy vegetables, since the residual amounts of ethoprophos in spinach were less than MRL (0.02 mg/kg). © 2021 The Korean Society of Environmental Agriculture. | Kwak, Se-Yeon; Lee, Sang-Hyeob; Kim, Hyo-Young; Shin, Byung-Gon; Kim, Jang-Eok | Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea; Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea; Safety Analysis Division, Experiment Research Institute, National Agricultural Products Quality Management Service, Gimcheon, 39660, South Korea; Safety Analysis Division, Experiment Research Institute, National Agricultural Products Quality Management Service, Gimcheon, 39660, South Korea; Major in Environment and Life Chemistry, School of Applied Biosciences, College of Agriculture and Life Sciences, Kyungpook National University, Daegu, 41566, South Korea | 57202752311; 57202747805; 57224535109; 59882223800; 7601387161 | jekim@knu.ac.kr; | Korean Journal of Environmental Agriculture | 1225-3537 | 40 | 2 | 0.08 | 2025-07-30 | 1 | Ethoprophos; Preceding crop; Succeeding crop; Translocation; Uptake | Russian | Final | 2021 | 10.5338/kjea.2021.40.2.11 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Use of the Human Broncho® Double-Lumen Tube in a Tracheal Bronchus Patient After Failed Lung Isolation with a Broncho-Cath™: A Case Report | Airway management for one-lung ventilation may be challenging for anesthe-siologists depending on the location of the tracheal bronchus orifice and possible anatomical distortions. Polyvinyl chloride double-lumen tube Broncho-Cath (TM) has been successfully used for one-lung ventilation in most cases of tracheal bronchus arising within 2 cm above the carina. However, there have been reports of occasional failure. A 78-year-old male patient diagnosed with secondary pneumothorax was scheduled for video-assisted thoracic surgery, and the tracheal bronchus originating 1.9 cm above the carina was shown in the preoperative chest computed tomography. Although a left-sided Broncho-Cath was initially placed, one-lung ventilation could not be achieved. Under bronchoscopy view through the tracheal lumen, the tracheal bronchus orifice was found to be partially obstructed. Furthermore, the bronchial cuff was herniated from the left main bronchus, leading to a failure of one-lung ventilation. The Broncho-Cath was replaced with a silicone double-lumen tube Human Broncho (R), which has more flexible bronchial segment and an increased marginal gap between the bronchial cuff and the tracheal lumen opening. The Human Broncho was successfully placed in an optimal position within the left main bronchus without blocking the tracheal bronchus orifice, thereby achieving the successful one-lung ventilation. The structurally unique Human Broncho may be considered as an alternative option in thoracic surgery of tracheal bronchus patients if lung isolation cannot be achieved with the Broncho-Cath. | Byun, Sung-Hye; Kim, Kyungmin | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Anesthesiol & Pain Med, 807 Hoguk Ro, Daegu 41404, South Korea | Byun, Sung Hye/AEK-1234-2022 | 56921446300; 57201480192 | stone0311@naver.com; | INTERNATIONAL MEDICAL CASE REPORTS JOURNAL | INT MED CASE REP J | 1179-142X | 14 | ESCI | MEDICINE, GENERAL & INTERNAL | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | tracheal bronchus; double-lumen tube; one-lung ventilation; thoracic surgery; case report | VENTILATION | Case report; Double-lumen tube; One-lung ventilation; Thoracic surgery; Tracheal bronchus | English | 2021 | 2021 | 10.2147/imcrj.s323263 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Usefulness of meshed SurgiMend in direct-to-implant breast reconstruction | Background The use of acellular dermal matrix in implant-based breast reconstruction immediately after mastectomy has attracted attention in recent years because it yields good outcomes. Herein, we analyzed the usefulness of meshed SurgiMend in direct-toimplant (DTI) breast reconstruction. Methods In this retrospective single-center analysis, 44 one-stage breast reconstructions using SurgiMend were performed in 42 patients from May 2016 to December 2017. The implant was inserted into the subpectoral plane and SurgiMend was applied to the inferolateral part that lacked tissues to wrap the silicone implant. In 19 patients (20 breasts), fenestration was performed with SurgiMend, while in the remaining 23 patients (24 breasts), SurgiMend that was meshed at a ratio of 1:1.5 was used. We analyzed the frequency of complications. Patient satisfaction was compared and analyzed using a five-item questionnaire (shape, texture, symmetry, pain, and overall outcome). Results The average age of the patients was 43.2 years, and their mean body mass index was 21.1 kg/m(2). The average follow-up period was 24.0 months. In the control (fenestrated SurgiMend) and experimental (meshed SurgiMend) groups, major seroma occurred in five of the 20 breasts (25.0%) and two of the 24 breasts (8.3%), respectively. Minor complications were resolved with conservative treatment. The patient satisfaction score for shape, texture, symmetry, pain, and overall satisfaction was 4.3, 4.1, 4.7, 4.5, and 4.4, respectively. Conclusions Applying meshed SurgiMend in DTI breast reconstruction is a useful surgical technique. | Eo, Pil Seon; Lee, Joon Seok; Lee, Jeong Woo; Choi, Kang Young; Chung, Ho Yun; Cho, Byung Chae; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug | Kyungpook Natl Univ, Dept Plast & Reconstruct Surg, Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | Yang, Jung/R-7806-2019; Lee, Jong-Mok/KVY-9550-2024; PARK, JUN-YOUNG/P-5981-2015; LEE, JIN/Q-3108-2018 | lambyang@knu.ac.kr; | ARCHIVES OF AESTHETIC PLASTIC SURGERY | ARCH AESTHET PLAST S | 2234-0831 | 2288-9337 | 27 | 2 | ESCI | SURGERY | 2021 | N/A | 3 | Breast implants; Acellular dermis; Surgical mesh; SurgiMend | ACELLULAR DERMAL MATRIX; FENESTRATIONS; EXPERIENCE; BOVINE | English | 2021 | 2021-04 | 10.14730/aaps.2020.02383 | 바로가기 | 바로가기 | 바로가기 |
