| ○ | Article | A Weighted Quadrangle Positioning Algorithm Using Automatic Distance Correction for Optimizing Indoor Positioning Accuracy | This paper adopts a weighted quadrangle positioning algorithm to achieve low cost, high accuracy and stable data transmission in indoor environment by utilizing FM radio signal and LTE-MTC technology. The weights from the center point to each indoor station are updated using the experimental linear program mode algorithm, and the distance between the target and the receiving station is corrected by dynamic weight values. The location of target position is calculated by combining the trigonometric positioning algorithm and the centroid algorithm. Compared with traditional positioning algorithms, this algorithm is more accurate and less interfered by combining distance automatic correction method and linear programming model. The experimental results show that the accuracy is improved by 6.207 and 4.1 times, respectively, compared with the FM-based triangulation positioning approach and FM-based weight triangulation approach. It not only improves the accuracy of indoor positioning, but also greatly reduces data transmission delay and energy consumption by the utilization of LTE-MTC technology. This technology can solve the localization problem of robots in intelligent factory and improve the cooperation ability between robots. © 2021, Korean Institute of Communications and Information Sciences.

| ○ | ○ | Article | A Workhorse Flap for Covering Moderate-sized Defects after Breast-conserving Surgery: Supercharged Lateral Thoracodorsal Flap | Background: The lateral thoracodorsal (LTD) flap technique is a type of oncoplastic breast surgery that involves transposition of tissue from the lateral aspect of a partial mastectomy defect. It is a relatively simple procedure and shows lower donor morbidity and good aesthetic outcomes. Complications, such as fat necrosis and wound dehiscence due to poor circulation, may occur at the distal part of the flap. We used a supercharged LTD flap to reduce this problem. In this study, the outcomes of the LTD flap over 13 years were reviewed. Methods: We performed a retrospective study of 86 patients who underwent an LTD flap procedure between 2007 and 2019. We analyzed patient information using medical chart review and classified patients into groups according to lateral thoracic artery perforator supercharging. The incidence of complications, such as fat necrosis and wound dehiscence, was also analyzed. Results: The mean tumor weight was 83.67 g, and defects had a moderate size, as they represented 25.02% of the total breast volume. Fat necrosis was noted in 19.4% of cases in the group without lateral thoracic artery perforator supercharging and 4% of cases in the group with supercharging, with a significantly lower rate in the supercharged group. Conclusions: Our findings show that the LTD flap could be used to cover moderate-sized defects after breast-conserving surgery. Careful dissection to preserve the lateral thoracic artery perforator resulted in the reduction of complications, such as fat necrosis, and excellent aesthetic results. | Kim, Do Gon; Choi, Dong Hun; Lee, Joon Seok; Lee, Jeong Woo; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 130 Dongdeokro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | Lee, Jong-Mok/KVY-9550-2024; LEE, JIN/Q-3108-2018; PARK, JUN-YOUNG/P-5981-2015; Yang, Jung/R-7806-2019 | 57208642340; 58587903800; 56496041000; 55892173700; 37079213100; 56564377200; 55171704700 | lambyang@knu.ac.kr; | PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN | PRS-GLOB OPEN | 2169-7574 | 9 | 2 | ESCI | SURGERY | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | PERFORATOR FLAPS; RECONSTRUCTION; EXPERIENCE | English | 2021 | 2021-02 | 10.1097/gox.0000000000003381 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||
| ○ | ○ | Proceedings Paper | A zero-crossing-based integrator with bidirectional two-phase charging and selective-reset operations for ΔΣ ADCs | Zero-crossing-based integrators (ZCBIs) are energy-efficient alternatives to conventional switched-capacitor integrators that are typically implemented using operational transconductance amplifiers (OTAs). However, ZCBIs suffer from signal-dependent overshoot errors and increased dynamic power consumption due to inherent reset operation. This paper presents a ZCBI that employs a bidirectional two-phase charging scheme and performs the reset operation selectively. A 3rd-order Delta-Sigma modulator has been fabricated in a 28-nm CMOS technology using the proposed integrators. The prototype modulator achieves 67-dB SNR and 63-dB SNDR over the bandwidth of 196 kHz with an oversampling ratio of 64. It consumes 184 mu W, which translates to the figure-of-merits of 154 dB (FoMs) and 390 fJ/conv-step (FoMw). | Min, Dong-Jick; Shim, Jae Hoon | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57207202364; 56245719400 | alsehdwlr@knu.ac.kr;jhshim@knu.ac.kr; | 2021 IEEE INTERNATIONAL SYMPOSIUM ON CIRCUITS AND SYSTEMS (ISCAS) | 0271-4302 | 0 | 2025-07-30 | 1 | 1 | Discrete-time Delta-Sigma ADC; Switched-Capacitor; Zero-Crossing-Based Integrator | Discrete-time delta-sigma ADC; Switched-capacitor; Zero-crossing-based integrator | Energy efficiency; Operational amplifiers; Signal to noise ratio; Charging scheme; CMOS technology; Delta sigma modulator; Dynamic power consumption; Energy efficient; Figure of merits; Over sampling ratio; Switched capacitor integrator; Modulators | English | 2021 | 2021 | 10.1109/iscas51556.2021.9401569 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Review | Absence of Reported cases of Microsporum ferrugineum, Trichophyton violaceum, and Trichophyton schoenleinii in South Korea | Dermatophytosis is a skin disorder caused by dermatophytes. Dermatophytes isolated in South Korea include Trichophyton (T.) rubrum, T. mentagrophytes, T. verrucosum, T. tonsurans, T. violaceum, T. schoenleinii, Microsporum (M.) canis, M. ferrugineum, M. gypseum, and Epidermophyton floccosum. T. tonsurans was first found in South Korea in 1992. In contrast, there have been no recent reported cases of T. violaceum, T. schoenleinii, and M. ferrugineum in South Korea. Population mobility, changes in human lifestyles, development of the healthcare system, and the introduction of antifungals have brought about dermatophyte evolution in the skin microenvironment. We have reviewed the cases of dermatophytosis caused by M. ferrugineum, T. violaceum, and T. schoenleinii reported both in South Korea and globally.

| ○ | ○ | Proceedings Paper | Accelerated On-Chip Algorithm based on Semantic Region-based Partial Difference Detection for LiDAR-Vision Depth Data Transmission Reduction in Lightweight Controller Systems of Autonomous Vehicle | LiDAR sensors are one type of sensor used in autonomous driving vehicles that obtain distance data through the flight time of light. A LiDAR sensor can measure data at high speeds, and the precision of the data is higher than with other sensors. A large amount of data per sensing time is transmitted from sensors. Autonomous driving vehicles use man electronic devices, so the data channels they use and the domain control unit resources that control the system are limited. In this environment, if LiDAR sensor data can be reduced without compromising the original data, it can have a quite positive impact on autonomous vehicle systems. In this paper, we propose a differential partial update for data reduction of LiDAR sensors and a semantic detection to eliminate the resulting noise and increase the reliability of the data. The sensor processor extracts only the changed parts of the continuous distance data, excluding the same parts, and transmit them to the host. The high-difference noise is eliminated by filtering through a window-sliding operation. Semantic detection marks only parts that change and detects movement in the field of view. Simple differential partial updates reduce the amount of data by 59.31% based on a simple case. A semantic detection partial update can reduce the amount of data by 83.41%. This process can also reduce computing time by 61.36% with graphics processing unit acceleration. | Jung, Dongkyu; Park, Daejin | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57223051842; 55463943600 | boltanut@knu.ac.kr; | 2021 IEEE 14TH INTERNATIONAL SYMPOSIUM ON EMBEDDED MULTICORE/MANY-CORE SYSTEMS-ON-CHIP (MCSOC 2021) | 0 | 2025-07-30 | 0 | 0 | Autonomous Vehicle; LiDAR; Partial Difference | Computer graphics; Data reduction; Graphics processing unit; Optical radar; Program processors; Semantics; Vehicle transmissions; Autonomous driving; Autonomous Vehicles; Difference detection; Distance datum; LiDAR; On chips; Partial difference; Partial updates; Region-based; Simple++; Autonomous vehicles | English | 2021 | 2021 | 10.1109/mcsoc51149.2021.00011 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Proceedings Paper | Accelerated Signal Processing of Burst-Mode Streamline Data for Low-Power Embedded Multi-Channel LiDAR Systems | Autonomous driving vehicle such as car or automated guided vehicle (AGV), requires sensors to detect obstacles in its surrounding environment and feed the information back to the vehicle control system. Light detection and ranging (LiDAR) sensors, which have attracted attention as effective sensors for autonomous driving, provide distance values measured within field of view using a laser to generate three-dimensional (3D) coordinates. 3D coordinates have the advantage of providing more precise measurements of an object's shape than other sensors and can also indicate the distance to the object. However, as the amount of data generated for a 3D point cloud and the number of sensors increases, the total amount of data to be processed increases. Therefore, the processing of this raw data in the main processor of an autonomous vehicle becomes a huge burden. In order to reduce the burden on the main processor of the autonomous vehicle, this paper intends to develop a real-time embedded system that primarily processes data from LiDAR sensors. | Chong, Taewon; Lee, Sanghoon; Oh, Cha-hwan; Park, Daejin | Hanyang Univ, Dept Phys, Seoul, South Korea; CARNAVICOM Co Ltd, Incheon, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57302218000; 57254873100; 7202497567; 55463943600 | boltanut@knu.ac.kr; | 2021 IEEE REGION 10 SYMPOSIUM (TENSYMP) | 2640-821X | 1.36 | 2025-07-30 | 1 | 8 | LiDAR sensor; embedded systems; parallel processing; low-power signal processing | embedded systems; LiDAR sensor; low-power signal processing; parallel processing | Automatic guided vehicles; Control system synthesis; Embedded systems; Optical radar; Parallel processing systems; Signal processing; Autonomous driving; Detection sensors; Embedded-system; Light detection and ranging; Light detection and ranging sensor; Low Power; Low-power signal processing; Parallel processing; Power signal processing; Ranging sensors; Autonomous vehicles | English | 2021 | 2021 | 10.1109/tensymp52854.2021.9550895 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Book chapter | Accumulation, partitioning, and bioavailability of micronutrients in plants and their crosstalk with phytohormones | Plants take micronutrients from the rhizosphere via roots and translocate them to the other parts (shoot and seeds). These nutrients are very much needed in plant tissues for effective completion of plant's metabolic functions thus their retention and assimilation in plant tissues is of utmost importance. During the whole process of nutrient uptake, translocation and assimilation, various pathways are involved to ensure effective delivery of these nutrients. Micronutrients make a major class of essential plant elements which are though required in very minute concnetrations but are very cruicial for plant's normal body functioning and health. Accumulation of these micronutrients in different plant parts depends upon the mobility of micronutrients within the plant body which is controled by several factors like production of phytohormones. The micronutrient-phytohormones interaction in plant body is very intresting as it brings several transitions in plant's biochemical processes over time. Being a two way interaction, the accumulation and partitioning of these micronutrients frequently control biosynthesis of various phytohormones which are helpfull in maintaing normal physiology of plants. Commulative effectiveness of micronutrient-phytohormones cross talk is an important phenomenon to be studied comprehensively. This chapter emphasizes the bioavailability, translocation, and accumulation of micronutrients considering their role in growth and physiology in plants and crosstalk with phytohormone. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2021.

| ○ | ○ | Article | Achyranthes japonica extracts supplementation to growing pigs positively influences growth performance, nutrient digestibility, fecal microbial shedding, and fecal gas emission | Objective: An experiment was conducted to investigate the effects of Achyranthes japonica extracts (AJE) on the growth performance, nutrient digestibility, fecal microbial shedding, and fecal gas emission of growing pigs. Methods: A total of 180 ([LandracexYorkshire]xDuroc) growing pigs with initial body weight (BW) of 23.94 +/- 1.54 kg were used in this study to investigate the effects of AJE as a feed additive. Dietary treatments included: i) CON (basal diet), ii) TRT1 (basal diet+0.05% AJE), and iii) TRT2 (basal diet+0.10% AJE). Results: As a result of the dietary supplementation of 0% to 0.10% AJE, a linear increase of BW (p<0.05) on d 21 and 42, a linear increase of average daily gain (ADG) (p<0.05) during d 21 to 42, a trend in linear increase of ADG (p<0.10) during d 0 to 21 and d 0 to 42, a linear increase of gain to feed ratio (G:F) (p<0.05) during d 0 to 42, and a tendency in the linear increase of G:F during d 21 to 42 were observed in this study. Additionally, dietary supple- mentation of 0% to 0.10% AJE had a linear increase (p<0.05) on the apparent total tract digestibility of dry matter (DM) and energy, a linear increase (p<0.05) on lactic acid bacteria counts, a tendency in reducing (linear effect, p<0.10) coliform bacteria counts, and a linear decrease (p<0.05) in excreta H2S emission content in growing pigs. Conclusion: In conclusion, the results suggested that AJE had the potential to enhance growth performance, DM and energy digestibility, and fecal lactic acid bacteria counts, and decrease the fecal coliform bacteria counts and excreta H2S emission in growing pigs. | Liu, Xiao; Lee, Sang In; Kim, In Ho | Dankook Univ, Dept Anim Resource & Sci, Cheonan 31116, South Korea; Northeast Agr Univ, Inst Anim Nutr, Harbin 150030, Peoples R China; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, South Korea | ; Kim, Ju-Hyoung/N-1450-2019 | 57211005795; 57203597336; 36050641300 | inhokim@dankook.ac.kr; | ANIMAL BIOSCIENCE | ANIM BIOSCI | 2765-0189 | 2765-0235 | 34 | 3 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE | 2021 | N/A | 2.1 | 2025-07-30 | 23 | 22 | Achyranthes japonica Extracts; Growth Performance; Nutrient Digestibility; Fecal Microbial Shedding; Fecal Gas Emissions; Growing Pigs | DIETARY SUPPLEMENTATION; BLOOD CHARACTERISTICS; LACTOBACILLUS SPP.; ESCHERICHIA-COLI; MEAT QUALITY; MICROFLORA | Achyranthes japonica extracts; Fecal gas emissions; Fecal microbial shedding; Growing pigs; Growth performance; Nutrient digestibility | English | 2021 | 2021-03 | 10.5713/ajas.20.0012 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Action Governor for Discrete-Time Linear Systems With Non-Convex Constraints | This letter introduces an add-on, supervisory scheme, referred to as Action Governor (AG), for discrete-time linear systems to enforce exclusion-zone avoidance requirements. It does so by monitoring, and minimally modifying when necessary, the nominal control signal to a constraint-admissible one. The AG operates based on set-theoretic techniques and online optimization. This letter establishes its theoretical foundation, discusses its computational realization, and uses two simulation examples to illustrate its effectiveness. | Li, Nan; Han, Kyoungseok; Girard, Anouck; Tseng, H.

| ○ | ○ | Article | Active Days around Solar Minimum and Solar Cycle Parameter | Utilizing a new version of the sunspot number and group sunspot number dataset available since 2015, we have statistically studied the relationship between solar activity parameters describing solar cycles and the slope of the linear relationship between the monthly sunspot numbers and the monthly number of active days in percentage (AD). As an effort of evaluating possibilities in use of the number of active days to predict solar activity, it is worthwhile to revisit and extend the analysis performed earlier. In calculating the Pearson's linear correlation coefficient r, the Spearman's rank-order correlation coefficient r(s), and the Kendall's tau coefficient with the rejection probability, we have calculated the slope for a given solar cycle in three different ways, namely, by counting the spotless day that occurred during the ascending phase and the descending phase of the solar cycle separately, and during the period corresponding to solar minimum +/- 2 years as well. We have found that the maximum solar sunspot number of a given solar cycle and the duration of the ascending phase are hardly correlated with the slope of a linear function of the monthly sunspot numbers and AD. On the other hand, the duration of a solar cycle is found to be marginally correlated with the slope with the rejection probabilities less than a couple of percent. We have also attempted to compare the relation of the monthly sunspot numbers with AD for the even and odd solar cycles. It is inconclusive, however, that the slopes of the linear relationship between the monthly group numbers and AD are subject to the even and odd solar cycles. | Chang, Heon-Young | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea | 7407524806 | hyc@knu.ac.kr; | JOURNAL OF ASTRONOMY AND SPACE SCIENCES | J ASTRON SPACE SCI | 2093-5587 | 2093-1409 | 38 | 1 | ESCI | ASTRONOMY & ASTROPHYSICS | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | Sun; sunspot numbers; data analysis | SUNSPOT ACTIVITY; ASSOCIATION; BEHAVIOR; NUMBERS | data analysis; Sun; sunspot numbers | English | 2021 | 2021-03 | 10.5140/jass.2021.38.1.23 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Conference paper | Active Stereo Vision Based 3D Reconstruction for Image Guided Surgery | We propose the 3D sensing system using active stereo vision to get the 3D model of human body parts and surgical tools. This article presents the 3D scanner based on active stereo vision utilized for image guided surgery. The proposed system comprises of a pair of cameras (stereo camera) and the projector to record images of the target object placed at a specific distance. The proposed approach also includes the pre-calibration of the stereo camera for removing the distortion from the image data using non-linear method. We have performed the camera calibration of stereo camera using undistorted image data to estimate camera parameters using chessboard target. This research uses NCC (normalized cross correlation) based stereo matching and this matching is reduced to single dimension by utilizing epipolar geometry. After estimating the matched points, DLT (direct linear transformation) is applied to render the 3D point clouds. The rendered 3D point clouds were further filtered to remove the background objects. This refinement stage includes removal of outliers, suppression of noise and smoothing. We tested the 3D scanning system using artificial skull and a paper box object for the demonstration of image guided surgery. The three dimensional sensing system using stereo vision and structured light was tested using the objects, skull and paper box objects. The three dimensional model (3D model) shows that the features are preserved. Post processing based filtering results in the refinement of the point clouds. To evaluate the proposed system, we used the paper box object and the 3D scans were captured. We found that the errors in the height and breadth were 9.4 μm and 23 μm respectively. Our system currently does not target real time applications, but the parallel processing and utilization of GPUs may reduce the processing time to meet the needs of real time surgical intervention. © 2021 IEEE. | Shirazi, Muhammad Ayaz; Khan, Danish; Affan, Muhammad; Poonja, Hasnain Ali; Ali Shah, Muhammad Soleman; Uddin, Riaz | School of Electronics Engineering, IT College, Kyungpook National University, Daegu, South Korea, Haptics, Human-Robotics And Condition Monitoring Lab, NED University of Engineering And Technology, Karachi, Pakistan; School of Electronics Engineering, IT College, Kyungpook National University, Daegu, South Korea; Haptics, Human-Robotics And Condition Monitoring Lab, NED University of Engineering And Technology, Karachi, Pakistan; Robotics And Intelligent Machine Engineering, SMME National University of Sciences And Technology (NUST), Islamabad, Pakistan; Robotics And Intelligent Machine Engineering, SMME National University of Sciences And Technology (NUST), Islamabad, Pakistan; NED University of Engineering And Technology, Haptics, Human-Robotics And Condition Monitoring Lab, Department of Electrical Engineering, Karachi, Pakistan | 55935434300; 57200212320; 57092607400; 57444964000; 57445183700; 55547397400 | mshirazi@ee.knu.ac.kr; | 2021 International Conference on Robotics and Automation in Industry, ICRAI 2021 | 0 | 2025-07-30 | 0 | 3D reconstruction; Camera calibration; Depth extraction; Image guided surgery; Stereo vision; Structured light | 3D modeling; Calibration; Cameras; Image reconstruction; Linear transformations; Program processors; Rendering (computer graphics); Stereo vision; Surgical equipment; Three dimensional computer graphics; 3D models; 3D reconstruction; 3d-modeling; Active stereo vision; Camera calibration; Depth extraction; Image guided surgery; Sensing systems; Stereo cameras; Structured Light; Stereo image processing | English | Final | 2021 | 10.1109/icrai54018.2021.9651353 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Acute antibody-mediated rejection limited to medullary lesions in following ABO-incompatible living donor kidney transplantation | Anatomical differences between the renal cortex and medulla may influence inflammatory responses. Owing to the difficulty in diagnosing rejections from the medulla, rejection is usually diagnosed through the cortex. However, previous studies have shown that there are no significant differences in renal cortical and medullary lesions in acute allograft rejection. A 60-year-old man with a history of diabetic nephropathy underwent kidney transplant from a living unrelated donor at our hospital in August 2019. Three days after surgery, his urine output suddenly decreased, whereas the serum creatinine levels increased. A kidney biopsy showed only medullary lesions with positive C4d-staining and a Banff score of PTC grade 3. He was diagnosed with acute antibody-mediated rejection (AMR) and treatment was initiated. He did not respond to conventional treatments, including plasma exchange and intravenous immunoglobulin, but his general condition improved after bortezomib administration. There have been a few cases of acute AMR limited to medullary lesions. We consider that rejection cannot be excluded even if the lesions are confined to the medulla. © 2021 Korean Journal of Transplantation.

| ○ | Book chapter | Adsorptive purification of water contaminated with hazardous organics by using functionalized metal-organic frameworks | Recently, the requirement for freshwater is increasing rapidly; however, on the other hand, contamination of water is severe or worsening. In this work, efforts to purify water contaminated with hazardous organics by using adsorption will be summarized. Adsorptive purification of water with metal-organic frameworks (MOFs), especially with functionalized MOFs, will be dealt. Not only the effect of a functional group on adsorption/purification but also the very brief method to introduce functionality onto MOFs will be introduced and analyzed. Finally, prospects of the field will be suggested for further development in the relevant fields. © Springer Nature Switzerland AG 2021. | Yoo, Dong Kyu; Bhadra, Biswa Nath; Jhung, Sung Hwa | Department of Chemistry, Green-Nano Materials Research Center, Kyungpook National University, Daegu, South Korea; Department of Chemistry, Green-Nano Materials Research Center, Kyungpook National University, Daegu, South Korea; Department of Chemistry, Green-Nano Materials Research Center, Kyungpook National University, Daegu, South Korea | 57201339246; 56982844300; 6701659467 | sung@knu.ac.kr; | Metal-Organic Frameworks in Biomedical and Environmental Field | 0 | 2025-07-30 | 0 | Adsorption; Functional groups; Hazardous organics; Mechanism; Metal-organic frameworks; Water | English | Final | 2021 | 10.1007/978-3-030-63380-6_8 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Review | Advanced technologies and mechanisms for yeast evolutionary engineering | In vitro evolution is a powerful technique for the engineering of yeast strains to study cellular mechanisms associated with evolutionary adaptation; strains with desirable traits for industrial processes can also be generated. There are two distinct approaches to generate evolved strains in vitro: The sequential transfer of cells in the stationary phase into fresh medium or the continuous growth of cells in a chemostat bioreactor via the constant supply of fresh medium. In culture, evolutionary forces drive diverse adaptive mechanisms within the cell to overcome environmental or intracellular stressors. Especially, this engineering strategy has expanded to the field of human cell lines; the understanding of such adaptive mechanisms provides promising targets for the treatment of human genetic diseases and cancer. Therefore, this technology has the potential to generate numerous industrial, medical, and academic applications. © 2020 Korean Society for Microbiology and Biotechnology.
