| ○ | ○ | Article | Endoscopic hemostasis using an over-the-scope clip for massive bleeding after percutaneous endoscopic gastrostomy removal: a case report | Percutaneous endoscopic gastrostomy (PEG) is a common method for providing long-term enteral nutrition to patients. PEG tube placement and removal are relatively safe generally, a PEG tube can be removed using gentle traction, and excessive bleeding is rare. The over-the-scope clip system is a new device that can be used for gastrointestinal hemostasis and for closing gastrointestinal fistulae. In the present case, a 68-year-old male patient had to remove the PEG tube because of persistent leakage around the PEG tube. Although it was gently removed using traction, incessant bleeding continued, with a Rockall score of 5 points, even after hemocoagulation was attempted. An over-the-scope clip device was used to achieve hemostasis and fistula closure. | Moon, Sun Young; Jung, Min Kyu; Heo, Jun | Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea | Kim, Young/J-5414-2012 | 57452826100; 56783168100; 36448170600 | minky1973@knu.ac.kr; | CLINICAL ENDOSCOPY | CLIN ENDOSC | 2234-2400 | 2234-2443 | 55 | 3 | ESCI | GASTROENTEROLOGY & HEPATOLOGY | 2022 | 2.5 | 0.26 | 2025-06-25 | 3 | 2 | Bleeding; Gastrocutaneous fistula; Over-the-scope clip; Percutaneous endoscopic gastrostomy | CLOSURE | Bleeding; Gastrocutaneous fistula; Over-the-scope clip; Percutaneous endoscopic gastrostomy | antineoplastic agent; hemoglobin; adjuvant chemotherapy; adjuvant therapy; aged; Article; aspiration pneumonia; bile duct carcinoma; bleeding; blood clotting; breathing rate; case report; clinical article; dysphagia; ECOG Performance Status; electrocoagulation; endoscopic hemostasis; follow up; gastrointestinal endoscopy; hemoglobin blood level; human; lung metastasis; male; percutaneous endoscopic gastrostomy; platelet count; prothrombin time; recurrent aspiration; Rockall score; stomach fistula; thrombocytopenia; tube removal | English | 2022 | 2022-05 | 10.5946/ce.2020.294 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Proceedings Paper | Energy-Efficient Precoding for Massive MIMO Systems with Low-Resolution Quantizers | In this paper, we propose a precoding method to maximize energy efficiency (EE) in a downlink multiuser massive multiple-input multiple-output system with low-resolution quantizers. To this end, we formulate an EE maximization problem with respect to precoders by incorporating the quantization errors caused by the low-resolution quantizers. The main challenges exist: i) the quantization errors are entangled with the precoders, ii) a objective function is non-convex, and iii) unlike a spectral efficiency (SE) maximization problem, a precoding power needs to be jointly optimized. To address these challenges, we first adopt a Dinkenbach method and reformulate the EE problem to a more tractable form. We further decompose the problem into an optimal precoding direction and transmit power problems. To find the optimal direction, we derive a first-order Karush-Kuhn-Tucker (KKT) condition and interpret the condition as a generalized eigenvalue problem. Accordingly, adopting a generalized power iteration-based precoding method, we find the principal eigenvector which is the best sub-optimal precoder. Regarding the transmit power optimization, the objective function becomes concave for given other variables. Hence, the transmit power level is optimized by using a gradient descent method. Via simulations, we demonstrate that the proposed algorithm provides the highest EE performance compared to baseline methods. | Oh, Mintaek; Park, Jeonghun; Lee, Namyoon; Choi, Jinseok | Ulsan Natl Inst Sci & Technol, Elect Engn, Ulsan 44919, South Korea; Kyungpook Natl Univ, Coll IT Engn, Daegu 41566, South Korea; POSTECH, Elect Engn, Pohang 37673, Gyeongbuk, South Korea | Choi, Jinseok/AAL-6383-2020; Aldhahir, Naofal/HCH-5192-2022; Lee, Namyoon/ADH-9232-2022 | 57710804900; 57853652900; 35148128800; 57190581671 | ohmin@unist.ac.kr;jeonghun.park@knu.ac.kr;nylee@postech.ac.kr;jinseokchoi@unist.ac.kr; | 2022 IEEE WIRELESS COMMUNICATIONS AND NETWORKING CONFERENCE (WCNC) | 1525-3511 | 0 | 2025-06-25 | 0 | 0 | ARCHITECTURES; MINIMIZATION; WIRELESS; DESIGN | Eigenvalues and eigenfunctions; Gradient methods; MIMO systems; Optimization; Energy efficient; Lower resolution; Maximization problem; Multiusers; Objective functions; Precoders; Precoding; Quantization errors; Quantizers; Transmit power; Energy efficiency | English | 2022 | 2022 | 10.1109/wcnc51071.2022.9771974 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | ○ | Proceedings Paper | Energy-Efficient Segment Clustering Algorithm for UAV trajectory | This paper proposes an energy-efficient clustering algorithm for UAV trajectory when a UAV scans massive IoT devices to collect data. The UAV trajectory power consumption in the scanning and data-collection process is mainly decided by the number of hovering points, path length, and collected data volume. These are then significantly affected by the number of grouped clusters of IoT devices and the amount of duplicate data collected from the repeatedly scanned IoT nodes in the overlapping areas of IoT clusters. Regarding this, we propose a low-complexity segment clustering (SC) algorithm aiming to appropriately group all the IoT devices into clusters with minimized overlap when considering the UAV communication range. The proposed SC algorithm is experimentally compared with existing clustering algorithms under five different topology scenarios. The numerical results show that the proposed SC algorithm outperforms its counterparts in most scenarios regarding the number of clusters, trajectory path length, and power consumption. | Mei, Haoran; Peng, Limei; Chang, Shih Yu; Zhang, Yin; Ho, Pin-Han | Kyungpook Natl Univ, Sch Comp Sci & Engn, Deagu, South Korea; San Jose State Univ, Dept Appl Data Sci, San Jose, CA 95192 USA; Univ Elect Sci & Technol, Sch Informat & Commun Engn, Chengdu, Sichuan, Peoples R China; Univ Waterloo, Dept Elect & Comp Engn, Waterloo, ON, Canada | Zhang, Yin/O-2149-2015 | 57208655106; 7201574271; 57221159388; 56298640900; 7402211578 | meihaoran@knu.ac.kr;auroraplm@knu.ac.kr;shihyu.chang@sjsu.edu;zhangyin123@uestc.edu.cn;p4ho@uwaterloo.ca; | 2022 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS WORKSHOPS (ICC WORKSHOPS) | 2164-7038 | 0.54 | 2025-06-25 | 1 | 2 | IoT; UAV; trajectory planning; data collection; clustering | clustering; data collection; IoT; trajectory planning; UAV | Data acquisition; Electric power utilization; Energy efficiency; Internet of things; Trajectories; Unmanned aerial vehicles (UAV); Clusterings; Data collection; Data collection process; Data volume; Energy efficient; Energy Efficient clustering; IoT; Overlapping area; Pathlengths; Trajectory Planning; Clustering algorithms | English | 2022 | 2022 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Conference paper | Enhanced Semi-persistent scheduling (e-SPS) for Aperiodic Traffic in NR-V2X | In cellular vehicle-to-everything (C-V2X) mode 4 and New Radio V2X (NR-V2X) mode 2 based on local observations resources are scheduled by the vehicles themselves. For resource scheduling operation third generation partnership project (3GPP) defined semi-persistent scheduling (SPS). Vehicles rely on the sensing information received in sidelink control information (SCI) over physical sidelink control channel (PSCCH). Based on the sensing information vehicle select the resources for its transmission and reserve the resources for its successive future transmissions. For periodic transmission, SPS works fine comparatively to aperiodic messages. Because aperiodic messages compelled the vehicle to select new resources for its transmission based on the latency associated with the generated packet. In turn, it results in unutilized resources which were reserved before. This would also increase resource contention. To overcome this, we have proposed the enhanced semi-persistent scheduling (e-SPS) method for resource reservation for aperiodic traffic. The proposed scheme utilizes the reinforcement learning mechanism where each vehicle act as an agent. Based on the traffic density and speed of the vehicle, the size of the sensing window is dynamically adjusted and re-evaluation mechanism is also introduced to confirm the available resources by performing the sensing again while selecting the resources. The performance of the proposed scheme is evaluated in ns-3 and compared with the naïve sensing mechanism. Results show that the e-SPS scheme outperforms the others. © 2022 IEEE. | Muhammad Saad, Malik; Ashar Tariq, Muhammad; Mahmudul Islam, Md.; Toaha Raza Khan, Muhammad; Seo, Junho; Kim, Dongkyun | Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea | 57220715290; 57563829800; 57223681377; 59158639500; 57208740581; 35753648800 | 4th International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2022 - Proceedings | 3.83 | 2025-06-25 | 15 | Aperiodic traffic; C-V2X; Cooperative Awareness Messages (CAMs); NR-V2X; Semi-Persistent Scheduling (SPS); Vehicular Communications | Cooperative communication; Reinforcement learning; Vehicle to Everything; Vehicle transmissions; Aperiodic messages; Aperiodic traffic; C-V2X; Cellulars; Cooperative awareness message; Local observations; New radio V2X; Semi-persistent scheduling; Sensing information; Vehicular communications; Scheduling | English | Final | 2022 | 10.1109/icaiic54071.2022.9722686 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | ○ | Proceedings Paper | Enhanced Velocity Estimation Based on Joint Doppler Frequency and Range Rate Measurements | Modern commercial radars estimate the velocity of target by measuring its Doppler frequency. However, there is a fundamental limit in the detectable Doppler frequency due to Nyquist sampling theorem. The velocity exceeding the maximum detectable velocity is aliased and folded back into the unambiguous detection region, which is known as velocity ambiguity. To address this issue, we propose a novel velocity disambiguation method which combines two velocity estimates with different properties. The first estimate is based on conventional Doppler frequency estimation method which is ambiguous but has high accuracy. The second estimate utilizes the range rate measured for multiple frames which is less accurate but unambiguous. These two estimates are combined to produce a single estimate that is accurate and unambiguous. Simulation results verified that the proposed method can successfully resolve the velocity ambiguity for every velocity values of interest. | Lim, Sohee; Jung, Jaehoon; Kim, Jihye; Kim, Seong-Cheol; Choi, Jeongsik | Seoul Natl Univ SNU, Dept Elect & Comp Engn, Seoul, South Korea; Seoul Natl Univ SNU, Inst New Media & Commun INMC, Seoul, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Choi, Jeongsik/ABA-6906-2020 | 57203931160; 57207233454; 57207437002; 22334016200; 58534394200 | gm10488@maxwell.snu.ac.kr;jay623@maxwell.snu.ac.kr;jihyekim224@maxwell.snu.ac.kr;sckim@maxwell.snu.ac.kr;jeongsik.choi@knu.ac.kr; | 2022 THIRTEENTH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS (ICUFN) | 2165-8528 | 2165-8536 | 1.01 | 2025-06-25 | 3 | 4 | Automotive radar; frequency-modulated continuous-wave (FMCW) radar; linear regression; velocity disambiguation | RADAR | Automotive radar; frequency-modulated continuous-wave (FMCW) radar; linear regression; velocity disambiguation | Automotive radar; Doppler effect; Frequency estimation; Frequency modulation; Radar measurement; Automotive radar; Detectable velocity; Doppler frequency; Frequency rate; Frequency-modulated-continuous-wave radars; Nyquist sampling theorem; Range-rate measurement; Velocity ambiguity; Velocity disambiguation; Velocity estimation; Velocity | English | 2022 | 2022 | 10.1109/icufn55119.2022.9829630 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Enhancement of waveform reconstruction for variational autoencoder-based neural audio synthesis with pitch information and automatic music transcription | In recent audio signal processing techniques, analysis and synthesis models based on deep generative models have been applied for various reasons, such as audio signal compression. Particularly, some recently developed structures such as vector-quantized variational autoencoders can compress speech signals. However, extending these techniques to compress audio and music signals is challenging. Recently, a realtime audio variational autoencoder (RAVE) method for high-quality audio waveform synthesis was developed. The RAVE method synthesizes audio waveforms better than conventional methods; however, it still encounters certain challenges, such as missing low-pitched notes or generating irrelevant pitches. Therefore, to be applied to audio reconstruction problems such as audio signal compression, the reconstruction performance should be improved. Thus, we propose an enhanced structure of RAVE based on a conditional variational autoencoder (CVAE) structure and automatic music transcription model to improve the reconstruction performance of music signal waveforms. © 2022 Proceedings of the International Congress on Acoustics.

| ○ | Article | Entropy and energy analysis of MHD nanofluid thermal transport in a non-uniformly heated annulus | In this analysis, nanoliquid motion and thermal dissipation rate along with the associated entropy production of water-based nanoliquid have been numerically investigated in an annular geometry. The vertical boundaries are imposed with sinusoidal thermal profiles with different phase deviations, while the top and bottom are retained as insulators, and an inclined external magnetic force has also been considered. The numerical experiments reveal that the change in phase deviation produces severe nanoliquid movement due to the shifting of hot and cold regions along with the outer cylinder. The enhancement of phase deviation produces higher thermal transport rates with minimal entropy production. The influence of magnetic field angle strongly depends on the magnitude of (Formula presented.) and also the thermal performance could be improved with a proper choice of magnetic tilt angle. Further, the entropy production in the annulus greatly depends on the intensity of the applied magnetic field. An increase in the nanoparticle concentration induces the thermal conductivity of nanoliquid and in turn improves the thermal transport. Through the present analysis, we identified a set of parameters to increase the thermal transport with minimum entropy production. © 2022 Informa UK Limited, trading as Taylor & Francis Group. | Kumara Swamy, H.A.; Sankar, M.; Do, Younghae | Department of Mathematics, CMR Institute of Technology, Bengaluru, India; Department of General Requirements, University of Technology and Applied Sciences-Ibri, Ibri, Oman; Department of Mathematics, KNU-Center for Nonlinear Dynamics, Kyungpook National University, Daegu, South Korea | 57223027638; 6701530391; 7103101109 | manisankariyer@gmail.com; | Waves in Random and Complex Media | 1745-5030 | 1.12 | 2025-06-25 | 12 | Entropy; Magnetohydrodynamics; Nanofluidics; Energy analysis; Entropy analysis; Entropy production; Heated annuli; Nanofluids; Nanoliquid; Phase deviations; Thermal dissipation rate; Thermal transport; Water based; Thermal conductivity | English | Article in press | 2022 | 10.1080/17455030.2022.2145522 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Book chapter | Environment and Geography | This chapter presents the climatic and geographical information for the Korean peninsula, which comprises today’s North and South Korea and lies in the temperate zone—between 33° and 43°N and between 124° and 132°E to be precise. The climatic data include precipitation, temperature, humidity, and wind speed from 1904–2015.

| ○ | ○ | Proceedings Paper | EPIPOLAR LINE-BASED LATERAL VIBRATION MEASUREMENT BY USING TWO CAMERAS | Vibration measurement techniques can be categorized into contact-type and non-contact-type techniques. These types of techniques can add mass-loading to a lightweight structure resulting in the negative performance of a structure, because sensors, high contrast speckles or targets should be mounted on a structure. Moreover, non-contact-type vibration measurement techniques have only been tested to detect vibrations using a single camera. As the vibrations occurring at the opposite sides of a rotating structure in a region of interest (ROI) can be different from each other. For 3-dimensional (3D) vibration measurement, the same position in videos acquired from two cameras should be used. Because the videos acquired by two cameras placed perpendicular to the structure can be used to detect the vibrations in the x-direction as well as y-direction. In this study, an epipolar line-based corresponding point selection on a rotating cylindrical structure was performed, to extract the same ROIs from videos recorded by two cameras. A fundamental matrix was constructed by using the targets attached on the structure and in the background. The coordinates of the mid-pixel of the ROI in a video acquired by one camera was used to determine the epipolar line for the same ROI in the video acquired by another camera. Then an edge-based vibration measurement technique was applied to measure the vibration in the extracted ROIs. The results were used to reconstruct a 3D vibration signal. The 3D vibration measurement results can be used to effectively recognize the deformations resulting in the negative performance of a structure. | Javed, Aisha; Park, Jueon; Lee, Hyeongill; Kim, Byeongil; Han, Youkyung | Seoul Natl Univ Sci & Technol, Dept Civil Engn, Seoul 01811, South Korea; Kyungpook Natl Univ, Sch Automot Engn, Sangju 37224, South Korea; Yeungnam Univ, Sch Mech Engn, Gyongsan 38541, South Korea | ; Javed, Aisha/LQK-3075-2024 | 57215897698; 57218222782; 8261483800; 56843890300; 55457676600 | javedaisha123@seoultech.ac.kr;jpark14@seoultech.ac.kr;hilee@knu.ac.kr;bikim@yu.ac.kr;han602@seoultech.ac.kr; | XXIV ISPRS CONGRESS IMAGING TODAY, FORESEEING TOMORROW, COMMISSION II | 1682-1750 | 2194-9034 | 43-B2 | 0.52 | 2025-06-25 | 1 | 2 | Target-less Photogrammetry; Epipolar Line; Vibration Detection; Subpixel-Based Edge Detection; Edge Tracking | POINT TRACKING; VISION | Edge Tracking; Epipolar Line; Subpixel-Based Edge Detection; Target-less Photogrammetry; Vibration Detection | Cameras; Edge detection; Image segmentation; Photogrammetry; Vibration measurement; 3-dimensional; Edge tracking; Epipolar line; Measurement techniques; Region-of-interest; Regions of interest; Sub-pixels; Subpixel-based edge detection; Target-less photogrammetry; Vibration detection; Pixels | English | 2022 | 2022 | 10.5194/isprs-archives-xliii-b2-2022-539-2022 | 바로가기 | 바로가기 | 바로가기 | |||||||||

| ○ | ○ | Article | Estimating dose-response curves using splines: a nonparametric Bayesian knot selection method | In radiation epidemiology, the excess relative risk (ERR) model is used to determine the dose-response relationship. In general, the dose-response relationship for the ERR model is assumed to be linear, linear-quadratic, linear-threshold, quadratic, and so on. However, since none of these functions dominate other functions for expressing the dose-response relationship, a Bayesian semiparametric method using splines has recently been proposed. Thus, we improve the Bayesian semiparametric method for the selection of the tuning parameters for splines as the number and location of knots using a Bayesian knot selection method. Equally spaced knots cannot capture the characteristic of radiation exposed dose distribution which is highly skewed in general. Therefore, we propose a nonparametric Bayesian knot selection method based on a Dirichlet process mixture model. Inference of the spline coefficients after obtaining the number and location of knots is performed in the Bayesian framework. We apply this approach to the life span study cohort data from the radiation effects research foundation in Japan, and the results illustrate that the proposed method provides competitive curve estimates for the dose-response curve and relatively stable credible intervals for the curve. | Lee, Jiwon; Kim, Yongku; Kim, Young Min | Kyungpook Natl Univ, Dept Stat, Daegu 41566, South Korea | 55780416700; 47962102500; 56035273800 | kymmyself@knu.ac.kr; | COMMUNICATIONS FOR STATISTICAL APPLICATIONS AND METHODS | COMMUN STAT APPL MET | 2287-7843 | 2383-4757 | 29 | 3 | ESCI | STATISTICS & PROBABILITY | 2022 | 0.4 | 0 | 2025-06-25 | 0 | 0 | Bayesian analysis; Dirichlet process mixture; dose-response estimation; excess relative risk; splines | PROCESS MIXTURE MODEL; DIRICHLET | Bayesian analysis; Dirichlet process mixture; Dose-response estimation; Excess relative risk; Splines | English | 2022 | 2022-05 | 10.29220/csam.2022.29.3.287 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Estimation of irrigation return flow from paddy fields on agricultural watersheds | Irrigation water supplied to the paddy field is consumed in the amount of evapotranspiration, underground infiltration, and natural and artificial drainage from the paddy field. Irrigation return flow is defined as the excess of irrigation water that is not consumed by evapotranspiration and crop, and which returns to an aquifer by infiltration or drainage. The research on estimating the return flow play an important part in water circulation management of agricultural watershed. However, the return flow rate calculations are needs because the result of calculating return flow is different depending on irrigation channel water loss, analysis methods, and local characteristics. In this study, the irrigation return flow rate of agricultural watershed was estimated using the monitoring and SWMM (Storm Water Management Model) modeling from 2017 to 2020 for the Heungeop reservoir located in Wonju, Gangwon-do. SWMM modeling was performed by weather data and observation data, water of supply and drainage were estimated as the result of SWMM model analysis. The applicability of the SWMM model was verified using RMSE and R-square values. The result of analysis from 2017 to 2020, the average annual quick return flow rate was 53.1%. Based on these results, the analysis of water circulation characteristics can perform, it can be provided as basic data for integrated water management. © 2022 Korea Water Resources Association. | Kim, Ha-Young; Nam, Won-Ho; Mun, Young-Sik; An, Hyun-Uk; Kim, Jonggun; Shin, Yongchul; Do, Jong-Won; Lee, Kwang-Ya | School of Social Safety and Systems Engineering, Hankyong National University, Anseong, South Korea; School of Social Safety and Systems Engineering, Institute of Agricultural Environmental Science, National Agricultural Water Research Center, Hankyong National University, Anseong, South Korea; National Agricultural Water Research Center, Hankyong National University, Anseong, South Korea; Department of Agricultural and Rural Engineering, Chungnam National University, Daejeon, South Korea; Department of Regional Infrastructure Engineering, Kangwon University, Chuncheon, South Korea; School of Agricultural Civil and Bio-Industrial Engineering, Kyungpook National University, Daegu, South Korea; Integrated Water Management Supporting Department, Water Resources Planning Office, Korea Rural Community Corporation, Sejong, South Korea; Institute of Agricultural Science, Chungnam National University, Daejeon, South Korea | 58248638000; 57198982117; 57220037505; 36639175600; 35435507500; 55659438100; 57211186617; 57211194318 | wonho.nam@hknu.ac.kr; | Journal of Korea Water Resources Association | 2799-8746 | 55 | 1 | 0.54 | 2025-06-25 | 6 | Agricultural water; Agricultural watershed; Irrigation network system; Irrigation return flow; Return flow rate; SWMM (storm water management model) | Korean | Final | 2022 | 10.3741/jkwra.2022.55.1.1 | 바로가기 | 바로가기 | ||||||||||||||||

In this study, basic volcanic rocks were subdivided by using polarizing microscope thin section images. A convolutional neural network (CNN) model based on Tensorfiow and Keras libraries was self-producted for rock classification. A total of 720 images of olivine basalt, basaltic andesite, olivine tholeiite, trachytic olivine basalt reference specimens were mounted with open nicol, cross nicol, and adding gypsum plates, and trained at the training : test = 7 : 3 ratio. As a result of machine learning, the classification accuracy was over 80-90%. When we confirmed the classification accuracy of each AI model, it is expected that the rock classification method of this model will not be much different from the rock classification process of a geologist. Furthermore, if not only this model but also models that subdivide more diverse rock types are produced and integrated, the AI model that satisfies both the speed of data classification and the accessibility of non-experts can be developed, thereby providing a new framework for basic petrology research. | Sim, Ho; Jung, Wonwoo; Hong, Seongsik; Seo, Jaewon; Park, Changyun; Song, Yungoo | Yonsei Univ, Dept Earth Syst Sci, Seoul 03722, South Korea; Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea | 57195558580; 57821156300; 57219895322; 57822168900; 56197393100; 7404920759 | yungoo@yonsei.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 55 | 3 | ESCI | GEOLOGY | 2022 | 0.3 | 0.12 | 2025-06-25 | 0 | 1 | artificial intelligence (AI); deep learning; convolutional neural network (CNN); basic volcanic rock; rock classification | artificial intelligence (AI); basic volcanic rock; convolutional neural network (CNN); deep learning; rock classification | Korean | 2022 | 2022-06 | 10.9719/eeg.2022.55.3.309 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Evaluation of a Follow-Up Health Consultation Program for Patients with Coronavirus Disease 2019 in Korea: Using the Context-Input-Process-Product Model | Beyond physical pain, patients with coronavirus disease 2019 (COVID-19) experience psychological anxiety during and after quarantine, often facing negative perceptions when returning to their communities. This study evaluated a health consultation program in Korea for post-quarantine patients with COVID-19, designed to help them return to their communities. The program was conducted from 9 March to 5 June 2020, in Daegu, Korea. In total, 20 doctors and 504 recovered patients were surveyed via questionnaire. The survey, comprising open-ended questions rated on a five-point Likert scale, was based on the Context-Input-Process-Product program evaluation model. Reliability was assessed, and descriptive statistics were obtained. A regression analysis was performed on factors affecting product (output) areas. As a main result, both doctors and recovered patients evaluated the program positively. The mean program effectiveness score was 4.00 in the doctors' evaluations and 3.95 in the patients' evaluations. Moreover, the input and process variables affected the product. This first-of-its-kind health consultation program proved to be an effective practical intervention for patients returning to the community after an infectious disease; it also highlights aspects that could increase satisfaction in systemized subsequent programs, with input and process areas for patients and doctors. | Lee, Keun-Mi; Ko, Hae-Jin; Lee, Geon Ho; Kim, Yun-A; Jung, Seung-Pil; Kim, A-Sol | Yeungnam Univ, Med Ctr, Coll Med, Dept Family Med, Daegu 42415, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Family Med, Daegu 41944, South Korea; Daegu Catholic Univ, Dept Family Med, Sch Med, Daegu 42472, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Family Med, Daegu 41404, South Korea | ; Lee, Geon Ho/HLG-1707-2023 | 56101036000; 54393415700; 36104322100; 57205025491; 55676012500; 57203290656 | kmlee@yu.ac.kr;liveforme@knu.ac.kr;totoslee@cu.ac.kr;yakim@cu.ac.kr;spjung@ynu.ac.kr;deepai@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 13 | 0 | 2025-06-25 | 0 | 0 | COVID-19; pandemic; consultation; context-input-process-product; evaluation | COVID-19 | consultation; context–input–process–product; COVID-19; evaluation; pandemic | COVID-19; Follow-Up Studies; Humans; Referral and Consultation; Reproducibility of Results; Republic of Korea; Korea; COVID-19; health care; input-output analysis; mental health; pandemic; perception; psychology; public health; adult; Article; community; consultation; context input process product model; controlled study; coronavirus disease 2019; female; follow up; human; Likert scale; major clinical study; male; model; open ended questionnaire; pandemic; patient; patient assessment; physician; program effectiveness; quarantine; regression analysis; reliability; retrospective study; satisfaction; South Korea; South Korean; statistics; epidemiology; follow up; patient referral; reproducibility | English | 2022 | 2022-07 | 10.3390/ijerph19137996 | 바로가기 | 바로가기 | 바로가기 |
