| ○ | ○ | Article | A study on the application of residual vector quantization for vector quantized-variational autoencoder-based foley sound generation model | Among the Foley sound generation models that have recently begun to be studied, a sound generation technique using the Vector Quantized-Variational AutoEncoder (VQ-VAE) structure and generation model such as Pixelsnail are one of the important research subjects. On the other hand, in the field of deep learning-based acoustic signal compression, residual vector quantization technology is reported to be more suitable than the conventional VQ-VAE structure. Therefore, in this paper, we aim to study whether residual vector quantization technology can be effectively applied to the Foley sound generation. In order to tackle the problem, this paper applies the residual vector quantization technique to the conventional VQ-VAE-based Foley sound generation model, and in particular, derives a model that is compatible with the existing models such as Pixelsnail and does not increase computational resource consumption. In order to evaluate the model, an experiment was conducted using DCASE2023 Task7 data. The results show that the proposed model enhances about 0.3 of the Frechet audio distance. Unfortunately, the performance enhancement was limited, which is believed to be due to the decrease in the resolution of time-frequency domains in order to do not increase of the resources. | Lee, Seokjin | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80, Daehak-ro, Daegu 41566, South Korea | 36174416200 | sjlee6@knu.ac.kr; | JOURNAL OF THE ACOUSTICAL SOCIETY OF KOREA | J ACOUST SOC KOREA | 1225-4428 | 2287-3775 | 43 | 2 | ESCI | ACOUSTICS | 2024 | 0.3 | 96.3 | 0 | 2025-04-16 | 0 | 0 | Foley sound generation model; Vector Quantized-Variational AutoEncoder (VQ-VAE); Residual vector quantization; Generative Model | Foley sound generation model; Generative Model; Residual vector quantization; Vector Quantized-Variational AutoEncoder (VQ-VAE) | English | 2024 | 2024 | 10.7776/ask.2024.43.2.243 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A study on the weakly-supervised deep learning algorithm for active sonar target recognition based on pseudo labeling using convolutional recurrent neural network model | In this paper, we proposed the weakly-supervised deep learning algorithm for active sonar target recognition based on pseudo labeling using Conventional Recurrent Neural Network (CRNN) model widely used for acoustic signal processing because it can effectively utilize small and unbalanced active sonar data. Active sonar simulation data assuming two different SNRs and clutter environments were used in the training and testing process, and spectrogram obtained by applying Short Time Fourier Transform (STFT) to the simulation data was used as a feature factor for algorithm training. The algorithm proposed in this paper was evaluated based on the target and nontarget F1-score using test data independent of training data. As a result, it was confirmed that the CRNN model showed significant performance not only in typical acoustic signal processing but also active sonar target recognition. Also, pseudo-labeling helps to improve the performance of the active sonar target recognition algorithm used the CRNN model. | You, Yena; Lee, Wonnyoung; Lee, Seokjin | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57861636800; 57860205200; 36174416200 | sjlee6@knu.ac.kr; | JOURNAL OF THE ACOUSTICAL SOCIETY OF KOREA | J ACOUST SOC KOREA | 1225-4428 | 2287-3775 | 43 | 5 | ESCI | ACOUSTICS | 2024 | 0.3 | 96.3 | 0 | 2025-05-07 | 0 | 0 | Active sonar; Target recognition; Weakly-supervised learning; Conventional Recurrent Neural Network (CRNN); Pseudo labeling | Active sonar; Conventional Recurrent Neural Network (CRNN); Pseudo labeling; Target recognition; Weakly-supervised learning | Korean | 2024 | 2024 | 10.7776/ask.2024.43.5.502 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Characteristics Control of Phytoncide-containing Copoly(Styrene-Acrylic Acid) Nanoparticles by Layer-by-Layer Assembly Method | Mean particle size, colloidal stability, and release profile of copoly(styrene-acrylic acid) nanoparticles were controlled by layer-by-layer (LbL) assembly method using chitosan (CS) and carboxy methylcellulose (CMC) aqueous solutions. From FTIR analysis, successful layer assembly of CS and CMC was confirmed. Optimum conditions of LbL assembly was also confirmed by scanning electro microscopy (SEM) and particle size analyzer (PSA) analyses. Colloidal stability was evaluated by measuring zeta potential of particles. Release profile of core material (phytoncide oil) was measured by using UV-Vis spectrophotometer and high performance liquid chromatography (HPLC). (St-AA)NP prepared by miniemulsion copolymerization shows mean particle size and zeta potential of 351.0 nm and-39.77 mV, respectively. Mean particle size of LbL assembled particles can be controlled from 351 nm to 2,803 nm by optimization of LbL assembly conditions. Zeta potential values above +/- 40 mV evidence the coilloidal stability of particles. LbL assembled particles show controlled release profiles of phytoncide oil over 2 months. | Kim, Minkwan; Moon, Sang Hyun; Yeo, Jiae; Do Ghim, Han | Kyungpook Natl Univ, Dept Text Syst Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Polythecn, Dept Carbon Fus New Mat, 222 Palgong Ro, Daegu 41027, South Korea | hdghim@knu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 48 | 5 | SCIE | POLYMER SCIENCE | 2024 | 0.6 | 96.3 | 0 | zeta potential; miniemulsion copolymerization; ccolloidal stability; sus- pended release | DRUG-RELEASE; DELIVERY | Korean | 2024 | 2024-09 | 10.7317/pk.2024.48.5.460 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

| ○ | ○ | Article | Preparation and Characterization of Poly(vinyl alcohol)/Tannin Blend Film for Active Food Packaging | The challenge for the food industry is to maintain or improve the quality of food products throughout the entire process of transportation, storage and consumption of foods. Hence, smart packaging technologies are actively studied in the food packaging industry. For instance, biomaterial-based food packaging technologies have been attempted in recent years owing to the abundance, biocompatibility, biodegradability, and non-toxicity of biopolymers. In this study, an active packaging film that can extend the shelf life of food was developed by blending tannic acid (TA), a natural polyphenolic compound with antioxidant and antibacterial activities, with poly(vinyl alcohol) (PVA), which is eco-friendly and has an excellent film-forming ability. The blend film was prepared via a simple solution-casting method, and its antioxidant and antibacterial properties, which can delay food spoilage, were evaluated. In addition, the anti-spoilage ability was evaluated in terms of browning and weight loss by packaging bananas, which are easily discolored during storage. Therefore, the PVA/TA blend film was found to extend the storage period of food. | Kim, Sung-Min; Choi, Yun Hyeok; Kim, Tae In; Lee, Cho Rok; Chae, Dong Wook; Jeon, Jong-Young; Choi, Jae-Woo; Shin, Bong-Seob; Kim, Min Hee; Park, Won Ho | Chungnam Natl Univ, Dept Organ Mat Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju 37224, South Korea | 59448034600; 57948595500; 58729381300; 59194184900; 59510685600; 59510718900; 59510734100; 59510751400; 57188948163; 57211114215 | mhkim88@knu.ac.kr;parkwh@cnu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 48 | 5 | SCIE | POLYMER SCIENCE | 2024 | 0.6 | 96.3 | 0 | 2025-05-07 | 0 | 0 | poly(vinyl alcohol); tannic acid; solution casting; active food packaging films. | COMPOSITE FILMS | active food packaging films; poly(vinyl alcohol); solution casting; tannic acid | Korean | 2024 | 2024-09 | 10.7317/pk.2024.48.5.536 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Preparation of Poly( γ- glutamic acid) Hydrogels with Ionic Liquids and Their Application as a Strain Sensor | In recent years, the increasing interest in health and fitness has led to enhanced research into wearable devices capable of monitoring various human body motions. Strain sensors, which are integrated into wearable devices, provide the capability to monitor bodily movements in real time by detecting the strain applied to the material due to changes in motion, heart rate, and blood pressure. This study investigates a polymer hydrogel composed of biocompatible poly(gamma glutamic acid) and an ionic liquid, developed as a strain sensor. The hydrogel exhibits notable flexibility, maintaining its functionality even when subjected to bending or stretching. Furthermore, it contains a substantial amount of water, facilitates ionic movement, and can emulate the softness and flexibility of human skin, thus demonstrating its potential for seamless integration into daily life. | Park, Jeong Jin; Kang, Yeong Min; Kim, Min Hee; Park, Won Ho | Chungnam Natl Univ, Dept Organ Mat Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju 37224, South Korea | 57949087800; 59446467100; 57188948163; 57211114215 | mhkim88@knu.ac.kr;parkwh@cnu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 48 | 6 | SCIE | POLYMER SCIENCE | 2024 | 0.6 | 96.3 | 0 | 2025-05-07 | 0 | 0 | poly(gamma-glutamic acid); ionic liquid; hydrogel; strain sensor; real-time motion monitoring | hydrogel; ionic liquid; poly(γ-glutamic acid); real-time motion monitoring; strain sensor | Korean | 2024 | 2024-11 | 10.7317/pk.2024.48.6.701 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Technology for Eco-friendly Special Coating Materials for Replacement of Plastics: Preparation and Characterization of Poly(vinyl alcohol)-based Crosslinked Films | After adding cross-linking agents such as maleic acid, succinic acid, and glutaraldehyde to poly(vinyl alcohol) (PVA), cross-linking was performed during drying process to cause water resistance and surface hydrophobization of the resulting film. The formation of cross-linked structure was confirmed through Fourier-transform infrared spectroscopy, and water resistance and surface hydrophobicity were evaluated by swelling degree and water contact angle. As the content of cross-linking agent increased, the swelling degree decreased and the contact angle increased. By adding the crystalline compounds, levan and reduced graphene oxide, hydrophobicity was further improved and PVA's low oxygen permeability was maintained. Consequently, the PVA composite film showed improved water resistance and surface hydrophobicity as well as excellent oxygen barrier properties due to the complementary contributions of the crosslinking agent and crystalline additive. Since almost all the components are inherently biodegradable, the present composite films are expected to be used as eco-friendly functional coatings. | Kim, Yoona; Kim, Heesang; Choi, So-Yun; Kim, Jinsoo; Ahn, Sung-Hun; Kwak, Giseop | Kyungpook Natl Univ, Dept Polymer Sci & Engn, 80 Daehak ro, Daegu 41566, South Korea; Green Package Solut Co Ltd, 18 Teheran ro,83 gil, Seoul 06169, South Korea | 59351757600; 57226091356; 59351526600; 59352215600; 59351874200; 17137322300 | gkwak@knu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 48 | 5 | SCIE | POLYMER SCIENCE | 2024 | 0.6 | 96.3 | 0 | 2025-05-07 | 0 | 1 | poly(vinyl alcohol); cross-linking agent; crystalline additive; water resistance; oxygen barrier | BARRIER PROPERTIES; GAS; LINKING | cross-linking agent; crystalline additive; oxygen barrier; poly(vinyl alcohol); water resistance | Chinese | 2024 | 2024-09 | 10.7317/pk.2024.48.5.503 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | The Beneficial Effects of Topical Cream Containing 17% of Herbal Extract on Skin Barrier Function: A Randomized Four-week Trial | Background: Skin moisture management is important for maintaining healthy skin and treating inflammatory skin diseases, and skin barrier function can be assessed by measuring trans-epidermal water loss (TEWL) and skin moisture content. Aim: This study was designed to investigate the effects of a topical cream containing 17% herbal extract (Cream17) on skin barrier function. Materials and methods: In this study, the ability of investigational product (IP) to improve skin barrier function was investigated in 33 subjects using a randomized and assessor-blinded four-week clinical trial. In our study, the effects of IP on TEWL, skin water content, and the degree of itching were investigated. Results: After four weeks of application, TEWL was significantly reduced by IP (p < .001), and skin water content was significantly increased (p < .001) compared to non-treated control. In addition, topical application of IP significantly lowered the visual analog scale at the second and fourth weeks after treatment commencement as compared with those in the untreated control group (visit 3 at the second week, p < .05; visit 4 at the fourth week, p < .001). Conclusion: These results indicate that Cream17 can improve the skin barrier function, which is important for managing dry skin conditions such as atopic dermatitis. | Lyu, Ji-Hyo; Kim, Soyeon; Kwon, Kang; Kim, Yongkuk; Choi, Chanhun; Jeong, Hyunwoo; Kim, Hyungwoo | Korea Inst Oriental Med, Herbal Med Resources Res Ctr, Naju, South Korea; Pusan Natl Univ, Res Inst Korean Med, Yangsan, South Korea; Pusan Natl Univ, Sch Korean Med, Dept Korean Med Ophthalmol & Otolaryngol & Dermato, Yangsan, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu, South Korea; Dongshin Univ, Coll Korean Med, Dept Physiol, Naju, South Korea; Dongshin Univ, Coll Korean Med, Dept Ophthalmol Otolaryngol & Dermatol, Naju, South Korea; Pusan Natl Univ, Korean Med Hosp, Natl Clin Res Ctr Korean Med, Yangsan 50612, South Korea | kronos7@pusan.ac.kr; | PHARMACOGNOSY MAGAZINE | PHARMACOGN MAG | 0973-1296 | 0976-4062 | 20 | 3 | SCIE | CHEMISTRY, MEDICINAL | 2024 | 0.9 | 96.5 | 0 | Atopic dermatitis; herbal medicine; moisturizing effect; skin barrier function; topical cream | CENTELLA-ASIATICA; DOUBLE-BLIND; DERMATITIS; PH | English | 2024 | 2024-09 | 10.1177/09731296241243129 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Analysis of Monoterpene Concentration Characteristics and Development of an Empirical Formula for Monoterpene in the Mixed Forest of the National Center for Forest Therapy | We analyzed the observed characteristics of monoterpene and developed an empirical formula for monoterpene concentration in the pine-dominated mixed forest of the National Center for Forest Therapy. Monoterpene was measured at 0800, 1200 and 1700 LST once a month using sorbent tube sampling coupled with thermal desorption gas chromatography and mass spectrometry. Monoterpene concentration is low in winter and shows a maximum in June and July. The major components of monoterpene are alpha-pinene, camphene and beta-pinene. During the warm period from May to November, monoterpene concentration is higher at 0800 and 1700 LST than at 1200 LST. The empirical formula takes into account the vegetation variables, temperature-controlled emission, oxidation processes and dilution by wind. The vegetation variable accounts for the difference in observed monoterpene concentration between two sites. The observed monoterpene concentration normalized by the vegetation variable increases exponentially with air temperature. The oxidation process explains the lower monoterpene concentration at 1200 LST than at 0800 and 1700 LST during the warm period. The monoterpene estimates using the empirical formula shows a correlation of 0.52 with the observation for the development period (2018 similar to 2020), while it shows a correlation of 0.72 for the validation year (2021). Such higher correlation for the validation year than for the development period is due to the fact that variability of monoterpene concentration is better explained by air temperature in 2021 than in the development period. However, the developed formula underestimates the monoterpene concentration in May and June, showing the limitation in accurately capturing the monthly variation of monoterpene. | Lee, Hyo-Jung; Lee, Young-Hee | Korea Forest Welf, Inst Forest Welf Res Ctr, Daejeon, South Korea; Kyungpook Natl Univ, Dept Atmospher Sci, 80 Daehakro, Daegu 41566, South Korea | young@knu.ac.kr; | ATMOSPHERE-KOREA | ATMOS-KOREA | 1598-3560 | 2288-3266 | 34 | 2 | ESCI | METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 0.6 | 96.8 | 0 | Monoterpene; Pine-dominated mixed forest; Empirical formula | VOLATILE ORGANIC-COMPOUNDS; SEASONAL-VARIATIONS; COMPOUND EMISSIONS; VOC CONCENTRATIONS; CONIFEROUS TREES; ELEVATED CO2; PINE FOREST; MODEL; LEAF | Korean | 2024 | 2024 | 10.14191/atmos.2024.34.2.187 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Effects of Parameters Defining the Characteristics of Raindrops in the Cloud Microphysics Parameterization on the Simulated Summer Precipitation over the Korean Peninsula | The study examines the effects of parameters that define the characteristics of raindrops on the simulated precipitation during the summer season over Korea using the Weather Research and Forecasting (WRF) Double-Moment 6-class (WDM6) cloud microphysics scheme. Prescribed parameters, defining the characteristics of hydrometeors in the WDM6 scheme such as a(R), b(R), and f(R) in the fall velocity (V-R) - diameter (D-R) relationship and shape parameter (mu(R)) in the number concentration (N-R) - D-R relationship, presents different values compared to the observed data from Two-Dimensional Video Disdrometer (2DVD) at Boseong standard meteorological observatory during 2018 similar to 2019. Three experiments were designed for the heavy rainfall event on August 8, 2022 using WRF version 4.3. These include the control (CNTL) experiment with original parameters in the WDM6 scheme; the MUR experiment, adopting the 50th percentile observation value for mu(R); and the MEDI experiment, which uses the same mu(R) as MUR, but also includes fitted values for a(R), b(R), and f(R) from the 50th percentile of the observed V-R - D-R relationship. Both sensitivity experiments show improved precipitation simulation compared to the CNTL by reducing the bias and increasing the probability of detection and equitable threat scores. In these experiments, the raindrop mixing ratio increases and its number concentration decreases in the lower atmosphere. The microphysics budget analysis shows that the increase in the rain mixing ratio is due to enhanced source processes such as graupel melting, vapor condensation, and accretion between cloud water and rain. Our study also emphasizes that applying the solely observed mu(R) produces more positive impact in the precipitation simulation. | Kim, Ki-Byung; Kim, Kwonil; Lee, GyuWon; Lim, Kyo-Sun Sunny | Kyungpook Natl Univ, Dept Atmospher Sci, Weather Extremes Educ & Res Team BK21, Daegu, South Korea; SUNY Stony Brook, Sch Marine & Atmospher Sci, Stony Brook, NY USA; Kyungpook Natl Univ, Ctr Atmospher REmote Sensing CARE, Daegu, South Korea | Kim, Kwonil/HTN-0103-2023; Lim, Kyo-Sun/I-3811-2012 | kyosunlim@knu.ac.kr; | ATMOSPHERE-KOREA | ATMOS-KOREA | 1598-3560 | 2288-3266 | 34 | 3 | ESCI | METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 0.6 | 96.8 | 0 | WDM6; 2DVD; Raindrops; Parameter; Summer precipitation | SIZE DISTRIBUTION; STATISTICAL CHARACTERISTICS; RAINY SEASONS; PART I; UNCERTAINTY; IMPLEMENTATION; DISDROMETER; SCHEME; MODEL; SNOW | Korean | 2024 | 2024 | 10.14191/atmos.2024.34.3.305 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | Episode Analysis of the Habit and Phase Changes of Snow Crystals in the Wintertime Yeongdong Region | The Yeongdong region has suffered from severe snowstorms and the relevant damage such as traffic accidents on slippery roads, and the collapse of greenhouses and temporary buildings. While a lot of research on snowfall has been conducted, the detailed study of snow crystals' phase and habit through intensive observations and the relevant microphysical analysis is still lacking. Therefore, a snowflake camera, PARSIVEL, and intensive radiosonde soundings were utilized to investigate phase and habit changes in solid precipitation. Two remarkable episodes of phase and habit changes were selected such as 19 March 2022 and 15 February 2023. Both events occurred in the synoptic condition of the High in the north and the Low passing by the south, which was accompanied by rapid temperature cooling below 2.5 km. During the events of a short period between 3 to 6 hours, the temperature at 850 hPa decreased by about 4 to 6 o C. This cooling led to a change in the main habit of snow particles from riming to aggregate, identified with both MASC and PARSIVEL. Meanwhile, the LDAPS model analyses do not successively represent the rapid cooling and short-term variations of solid precipitation, probably by virtue of overestimating low-level equivalent potential temperature during these periods. The underlying causes of these the low-level temperature variations within 6 hours, still remain unclear. It might be associated with mesoscale orographic phenomenon due to the mountains and East Sea effects, which certainly needs an intensive and comprehensive observation campaign. | Choi, Young -Gil; Kim, Byung-Gon; Kim, Ji-Yun; Kim, Tae-Yeon; Han, Jin-Heon; Lee, Gyuwon; Kim, Kwonil; Kim, Ki-Hoon; Lim, Byung-Hwan | Natl Inst Meteorol Sci, Observat Res Dept, Jeju 63568, South Korea; Gangneung Wonju Natl Univ, Dept Atmospher Environm Sci, 7 Jukheon Gil, Kangnung 25457, Gangwon, South Korea; Kyungpook Natl Univ, Ctr Atmospher Remote Sensing CARE, Dept Atmospher Sci, BK21 Weather Extremes Educ & Res Team, Daegu, South Korea; SUNY Stony Brook, Sch Marine & Atmospher Sci, Stony Brook, NY USA; Natl Inst Meteorol Sci, High Impact Weather Res Lab, Kangnung, South Korea | Kim, Ji-Yun/ABG-5983-2020; Kim, Kwonil/HTN-0103-2023; Kim, Byung Gon/HPF-1667-2023 | bgk@gwnu.ac.kr; | ATMOSPHERE-KOREA | ATMOS-KOREA | 1598-3560 | 2288-3266 | 34 | 2 | ESCI | METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 0.6 | 96.8 | 0 | Phase and habit changes; Riming; Aggregate; Rapid cooling | COLD; CLASSIFICATION; PRECIPITATION; DENSITY | English | 2024 | 2024 | 10.14191/atmos.2024.34.2.139 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Carbon Dioxide-based Plastic Pyrolysis for Hydrogen Production Process: Sustainable Recycling of Waste Fishing Nets | Fishing net waste (FNW) constitutes over half of all marine plastic waste and is a major contributor to the degradation of marine ecosystems. While current treatment options for FNW include incineration, landfilling, and mechanical recycling, these methods often result in low-value products and pollutant emissions. Importantly, FNWs, comprised of plastic polymers, can be converted into valuable resources like syngas and pyrolysis oil through pyrolysis. Thus, this study presents a process for generating high-purity hydrogen (H-2) by catalytically pyrolyzing FNW in a CO2 environment. The proposed process comprises of three stages: First, the pretreated FNW undergoes Ni/SiO2 catalytic pyrolysis under CO2 conditions to produce syngas and pyrolysis oil. Second, the produced pyrolysis oil is incinerated and repurposed as an energy source for the pyrolysis reaction. Lastly, the syngas is transformed into high-purity H-2 via the Water-Gas-Shift (WGS) reaction and Pressure Swing Adsorption (PSA). This study compares the results of the proposed process with those of traditional pyrolysis conducted under N-2 conditions. Simulation results show that pyrolyzing 500 kg/h of FNW produced 2.933 kmol/h of high-purity H-2 under N-2 conditions and 3.605 kmol/h of high-purity H-2 under CO2 conditions. Furthermore, pyrolysis under CO2 conditions improved CO production, increasing H-2 output. Additionally, the CO2 emissions were reduced by 89.8% compared to N-2 conditions due to the capture and utilization of CO2 released during the process. Therefore, the proposed process under CO2 conditions can efficiently recycle FNW and generate eco-friendly hydrogen product. | Kim, Yurim; Lee, Seulgi; Jung, Sungyup; Lee, Jaewon; Cho, Hyungtae | Korea Inst Ind Technol, Green Mat & Processes R Grp, Ulsan 44413, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, Seoul 03722, South Korea; Korea Univ Technol & Educ, Dept Appl Chem Engn, Cheonan 31253, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Jung, Sungyup/GZG-6207-2022 | 57295145100; 59849600700; 55073290800; 57200543537; 55326115100 | kyr0602@yonsei.ac.kr;kwl9808@naver.com;sjung001@knu.ac.kr;j.lee@kitech.re.kr;htcho@kitech.re.kr; | KOREAN CHEMICAL ENGINEERING RESEARCH | KOREAN CHEM ENG RES | 0304-128X | 2233-9558 | 62 | 1 | ESCI | ENGINEERING, CHEMICAL | 2024 | 0.3 | 96.9 | 0 | 2025-05-07 | 0 | 0 | Waste-to-energy; Fishing net waste; Pyrolysis; Carbon dioxide; Hydrogen | ENERGY RECOVERY; CO2; GENERATION; SIMULATION; BIOMASS | Carbon dioxide; Fishing net waste; Hydrogen; Pyrolysis; Waste-to-energy | Korean | 2024 | 2024-02 | 10.9713/kcer.2024.62.1.36 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Analysis of effect of global uncertainty on domesticuncertainty using connectedness index | This study estimates connectedness index among the US, China, Europe, Japan, and South Korea usingmonthly economic policy uncertainty (EPU) data from January 2000 to December 2023. The connectedness in-dex allows us to analyze the effect of global economic uncertainty on domestic economic uncertainty. The EPUis used as a proxy for economic uncertainty. Inter-country connectedness index is computed from variance de-composition. The findings from forecast error variance decomposition show that three-fourths of total uncertaintycomes from economic uncertainty in the own country and one-fourth of total uncertainty comes from economicuncertainty in the others. The analysis on net pairwise connectedness reveals that, even though the extent of theeffect of economic uncertainty in one country from economic uncertainty in another country varies over time,economic uncertainty in South Korea, a small-open economy, is mainly affected by economic uncertainty in theothers. The reverse situation rarely happens except in the specific occurrence such as the collapse of the creditbubble in 2003 and the subsequent years, the inter-Korean summit and North Korea-the US summit in 2018, andthe period from the first outbreak of COVID-19 on the implementation of the government's severe regulationagainst COVID-19. | Kwon, Sanguk; Hwang, Sun Ho | Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea; Natl Pens Res Inst, Actuarial Financial Project Div, Giji Ro 170, Jeonju Si 54870, Jeollabuk Do, South Korea | Hwang, Sun Ho/IAN-2107-2023 | sunho3137@gmail.com; | KOREAN JOURNAL OF APPLIED STATISTICS | KOREAN J APPL STAT | 1225-066X | 2383-5818 | 37 | 4 | ESCI | STATISTICS & PROBABILITY | 2024 | 0.2 | 97.3 | 0 | global uncertainty; economic policy uncertainty index; connectedness index; structural vectorautoregressive model; forecast error variance decomposition | SPILLOVERS | English | 2024 | 2024-08 | 10.5351/kjas.2024.37.4.509 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Clinical Outcomes of Topical Bromfenac Combined with Intravitreal Aflibercept Injection for Exudative Age-related Macular Degeneration | Purpose: To evaluate the efficacy of topical bromfenac combined with intravitreal aflibercept (IVA) injection in the treatment of exudative age-related macular degeneration over a 2-year period. Methods: We retrospectively studied 43 patients (43 eyes) with exudative age-related macular degeneration. Patients were included if they received IVA injections under an as-needed protocol and had > 2 years of follow-up. Among the 43 eyes, 25 received only IVA (IVA group), whereas 18 received a combination of IVA and topical bromfenac (bromfenac group). The primary outcome measure was the total number of IVA injections administered over 2 years from the initial injection compared between groups. We also compared changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) between groups. Results: The bromfenac group received a significantly lower number of IVA injections over 2 years (7.4 +/- 1.0), compared with the IVA group (9.0 +/- 1.9) (p < 0.01). Both groups showed improvements in BCVA and CRT after 2 years compared with their baseline values. However, changes in BCVA and CRT at 2 years did not significantly differ between groups (p = 0.786 and p = 0.905, respectively). Conclusions: Among patients with exudative age-related macular degeneration, the total number of IVA injections over 2 years was lower in the bromfenac group than in the IVA group. More studies are needed to confirm the efficacy of topical bromfenac in a combined treatment regimen. | Kwon, Mi Sun; Kim, Jin Young; Kim, Yu Min; Do, Jae Rock; Kang, Yong Koo; Shin, Jae Pil; Park, Dong Ho | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 41944, South Korea | KANG, YONG KOO/IVH-8723-2023 | 58734575300; 57198434314; 57211041082; 58600232100; 57204703736; 56517350400; 36676632900 | Dongho_Park@knu.ac.kr; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 65 | 1 | ESCI | OPHTHALMOLOGY | 2024 | 0.1 | 97.4 | 1.08 | 2025-04-16 | 1 | 1 | Aflibercept; Age-related macular degeneration; Bromfenac | VEGF TRAP; RANIBIZUMAB; PATHOGENESIS; INFLAMMATION; BEVACIZUMAB | Aflibercept; Age-related macular degeneration; Bromfenac | Korean | 2024 | 2024-01 | 10.3341/jkos.2024.65.1.27 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of 0.625% Intravitreal Povidone-iodine injections in Patients with Endophthalmitis | Purpose: We report on three patients who received 0.625% povidone-iodine (PVI) intravitreal injections to treat endophthalmitis that did not respond to conventional antibiotic treatment or were inoperable. Case summary: Case 1 was a 42-year-old female with suspected left-eye endophthalmitis that developed after anterior chamber irrigation to treat silicone oil emulsification. A 0.625% PVI intravitreal injection reduced inflammation of the anterior chamber and the vitreous. Case 2 was an 84-year-old male who was blind in the left eye due to glaucoma. He was diagnosed with endogenous endophthalmitis on the basis of the anterior chamber hypopyon and vitreous inflammation. After 0.625% PVI intravitreal injection, the endophthalmitis resolved without any recurrence. Case 3 was a 49-year-old female with suspected endogenous left-eye endophthalmitis attributable to a liver abscess. Despite intravitreal antibiotic injections, the inflammation worsened. A 0.625% PVI intravitreal injection improved both the anterior chamber and vitreous inflammation. Conclusions: Intravitreal 0.625% PVI injection is a useful option when a patient with endophthalmitis is likely to not recover full vision, when surgery cannot be performed, and when there is no response to empirical antibiotics. | Cho, Jun Hee; Yae, Che Gyem; Kim, Jin Young; Do, Jae Rock; Kang, Yong Koo; Shin, Jae Phil; Park, Han Sang | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Nune Eye Hosp, 2179 Dalgubeol Daero, Daegu 41940, South Korea | KANG, YONG KOO/IVH-8723-2023 | 59293910800; 56048982200; 57198434314; 58600232100; 57204703736; 59294394300; 57208186456 | fhak02@naver.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 65 | 8 | ESCI | OPHTHALMOLOGY | 2024 | 0.1 | 97.4 | 0 | 2025-05-07 | 0 | 0 | Endophthalmitis; Intravitreal injection; Povidone iodine | STAPHYLOCOCCUS-EPIDERMIDIS | Endophthalmitis; Intravitreal injection; Povidone iodine | Korean | 2024 | 2024-08 | 10.3341/jkos.2024.65.8.550 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
