| ○ | ○ | Article | Overaccumulation of Fat Caused Rapid Reproductive Senescence but not Loss of Ovarian Reserve in ob/ob Mice | Ovarian reserve and fertility are reduced by aging and a poor energy balance. To date, the relationships of high energy accumulation and aging with the ovarian reserve have not been elucidated. Here, the effects of obesity on the aging ovarian reserve were evaluated in a leptin-deficient (ob/ob) mouse model. Abnormal estrous cyclicity appeared as early as 6 weeks and worsened with aging. The blood level patterns of 17 beta-estradiol (E2), testosterone (T), and progesterone (P4) with aging were similar between lean and ob/ob mice. The blood level of E2 but not P4 or T was similar at 24 weeks. Many more atretic follicles but fewer corpora lutea were observed in ob/ob mice than in lean mice within all age groups. Anti-Mullerian hormone (Amh) mRNA levels were similar between genotypes. Dazl, Stra8, and ZP3 mRNAs were highly expressed in ob/ob mice after 12 weeks. Sohlh1 and Ybx2 mRNAs were highly expressed at 24 weeks in ob/ob compared with lean mice. In addition, SOHLH1-positive primordial follicle counts were significantly increased in ob/ob mice at 24 weeks. The proportions of AMH-positive secondary and small antral follicles were similar between genotypes. Together, these results show that the ovarian reserve lasts longer in ob/ob mice than in lean mice, suggesting that the loss of normal physiological or physical status causes decreased fertility at a young age in ob/ob mice and that an increase in adipocytes without leptin, as in ob/ob mice, can improve the ovarian reserve. Such knowledge can be applied to understanding reproductive dysfunction. | Mollah, Mohammad Lalmoddin; Yang, Hee-Seon; Jeon, SoRa; Kim, KilSoo; Cheon, Yong-Pil | Sungshin Women Univ, Sch Biosci & Chem, Div Dev & Physiol, Seoul 02844, South Korea; Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea | 12809281600; 57221776027; 57221776125; 35272034300; 7003693398 | ypcheon@sungshin.ac.kr; | JOURNAL OF THE ENDOCRINE SOCIETY | J ENDOCR SOC | 2472-1972 | 5 | 1 | ESCI | ENDOCRINOLOGY & METABOLISM | 2021 | N/A | 0.09 | 2025-07-30 | 1 | 1 | ob/ob; fertility; ovarian reserve; sex steroid hormone; meiosis-stage marker | fertility; meiosis-stage marker; ob/ob; ovarian reserve; sex steroid hormone | estradiol; fat; leptin; messenger RNA; Muellerian inhibiting factor; progesterone; testosterone; adipocyte; animal cell; animal experiment; animal model; animal tissue; antral follicle; Article; cell aging; controlled study; corpus luteum; estradiol blood level; female; gene expression; genotype; meiosis; mouse; nonhuman; ob/ob mouse; obesity; ovarian reserve; primordial follicle; priority journal; reproduction | English | 2021 | 2021-01 | 10.1210/jendso/bvaa168 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Overcoming issues in frequency-based extraction and lexicographic inclusion of korean neologisms: A triangulation approach | This paper discusses issues regarding frequency as a criterion for Korean neologism extraction from the perspective of corpus linguistics and lexicography. Most studies agree that frequency plays a central role in the inclusion of neologisms in the dictionary; however, frequency entails a number of complex factors such as the time span of a word’s use as well as the variety of registers. The use of web data to extract neologisms – instead of a balanced corpus – has brought about a new range of issues that call for new ways to address them. Section 2 reviews previous research trends related to neologism frequency from the point of view of linguistics and neologism studies. Section 3 examines and discusses issues in the detection of phrasal and semantic neologisms, and in the use of Web corpora. Section 4 suggests the use of triangulation in order to cope with such shortcomings, combining use-based methodology and used-based approach. © 2021, equinox publishing. | Nam, Kilim | Department of Korean Language and Literature, Kyungpook National University, Daegu, South Korea | 57217067723 | nki@knu.ac.kr; | Lexicography | 2197-4292 | 8 | 1 | 0.24 | 2025-07-30 | 3 | Neologism; Phrasal neologism; Semantic neologism; Triangulation approach; Web corpus | English | Final | 2021 | 10.1558/lexi.19481 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Overexpression of Rice OsS1Fa1 Gene Confers Drought Tolerance in Arabidopsis | Small peptides and proteins play critical regulatory roles in plant development and environmental stress responses; however, only a few of these molecules have been identified and characterized to date because of their poor annotation and other experimental challenges. Here, we present that rice (Oryza sativa L.) OsS1Fa1, a small 76-amino acid protein, confers drought stress tolerance in Arabidopsis thaliana. OsS1Fa1 was highly expressed in leaf, culm, and root tissues of rice seedlings during vegetative growth and was significantly induced under drought stress. OsS1Fa1 overexpression in Arabidopsis induced the expression of selected drought-responsive genes and enhanced the survival rate of transgenic lines under drought. The proteasome inhibitor MG132 protected the OsS1Fa1 protein from degradation. Together, our data indicate that the small protein OsS1Fa1 is induced by drought and is post-translationally regulated, and the ectopic expression of OsS1Fa1 protects plants from drought stress. | Kim, Sung-Il; Lee, Kyu Ho; Kwak, Jun Soo; Kwon, Dae Hwan; Song, Jong Tae; Seo, Hak Soo | Seoul Natl Univ, Res Inst Agr & Life Sci, Dept Agr Forestry & Bioresources, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | 57206875788; 57204416526; 57188934445; 57216938492; 57797134000; 26642769200 | icuts@snu.ac.kr;leehotl@snu.ac.kr;kchhy88@snu.ac.kr;kdh9495@snu.ac.kr;jtsong68@knu.ac.kr;seohs@snu.ac.kr; | PLANTS-BASEL | 2223-7747 | 10 | 10 | 0.5 | 2025-07-30 | 6 | 6 | small protein; rice; OsS1Fa1; drought stress; post-translational modification | POSTTRANSLATIONAL MODIFICATIONS; ELECTROPHORETIC MOBILITY; SIGNAL-TRANSDUCTION; PROTEIN-STRUCTURE; STRESS-RESPONSE; EXPRESSION; PEPTIDES; BINDING; SALT; ELEMENT | Drought stress; OsS1Fa1; Post-translational modification; Rice; Small protein | English | 2021 | 2021-10 | 10.3390/plants10102181 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Book chapter | Oxides free nanomaterials for (photo)electrochemical water splitting | The continuously increasing energy demand due to population growth has caused rapid consumption of fossil fuels and severe environmental issues. Hence, sustainable energy production via photoelectrochemical water splitting (PECWS) technique by using nanostructured materials has become an important approach to solve the energy demands. Especially, the oxide-free nanostructured materials like metal nitrides (MNs), metal phosphides (MPs), and metal sulfides (MSs) have become promising candidates for the PEC water splitting applications. Therefore, in this book chapter, we have discussed the important properties of oxide-free materials for efficient PEC hydrogen generation. We have highlighted the synthesis mechanisms of binary and ternary metal nitrides, phosphides, and sulfides of various structures and recent advances of these fascinating nanomaterials for PEC hydrogen generation and important properties and mechanisms helpful for improved activities. Finally, we discussed the important challenges and future prospects in this field for efficient solar hydrogen generation. © 2022 Elsevier Inc.

| ○ | ○ | Article | Performance analysis of weakly-supervised sound event detection system based on the mean-teacher convolutional recurrent neural network model | This paper introduces and implements a Sound Event Detection (SED) system based on weakly-supervised learning where only part of the data is labeled, and analyzes the effect of parameters. The SED system estimates the classes and onset/offset times of events in the acoustic signal. In order to train the model, all information on the event class and onset/offset times must be provided. Unfortunately, the onset/offset times are hard to be labeled exactly. Therefore, in the weakly-supervised task, the SED model is trained by "strongly labeled data" including the event class and activations, "weakly labeled data" including the event class, and "unlabeled data" without any label. Recently, the SED systems using the mean-teacher model are widely used for the task with several parameters. These parameters should be chosen carefully because they may affect the performance. In this paper, performance analysis was performed on parameters, such as the feature, moving average parameter, weight of the consistency cost function, ramp-up length, and maximum learning rate, using the data of DCASE 2020 Task 4. Effects and the optimal values of the parameters were discussed. | Lee, Seokjin | Kyungpook Natl Univ, Sch 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 | 40 | 2 | ESCI | ACOUSTICS | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | Sound event detection; Semi-supervised learning; Mean-teacher; Convolutional recurrent neural network | Convolutional recurrent neural network; Mean-teacher; Semi-supervised learning; Sound event detection | Korean | 2021 | 2021 | 10.7776/ask.2021.40.2.139 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Performance evaluation and prediction of asr-deteriorated concrete median barrier subjected to impact loading | CMBs (Concrete Median Barriers) in service along expressways are deteriorated by deicing chemicals, the freeze-thaw and ASR (Alkali-Silica Reaction), leading to a decrease in structural performance of CMBs subjected to impact loads of moving vehicles. It is necessary to provide appropriate maintenance activities to deteriorated CMBs in order to improve the safety of expressway users. This paper aims at evaluating structural performance of degraded CMBs and suggesting the timing for rehabilitation. Two deterioration models for the CMBs were proposed: ① the depth 30 mm deterioration model and ② the stage deterioration model, based on field investigations. Numerical analysis of vehicle collisions were carried out via the proposed deterioration models with varying extents of deterioration. Results obtained from numerical simulations indicate that appropriate maintenance activities should be performed before Deterioration Stage 3, when randomly distributed cracks expand up to 750 mm from pavement surface. ⓒ2021 by Korea Concrete Institute. | Jeong, Yoseok; Lee, Ilkeun; Lee, Jaeha; Min, Geunhyeong; Kim, Wooseok | Department of Construction and Disaster Prevention Engineering, Kyungpook National University, Sangju, 37224, South Korea; Expressway & Transportation Research Institute, Construction & Environment Research Group, Hwaseong, 20896, South Korea; Department of Civil Engineering, Korea Maritime and Ocean University, Pusan, 49112, South Korea; Department of Civil Engineering, Chungnam National University, Daejeon, 34134, South Korea; Department of Civil Engineering, Chungnam National University, Daejeon, 34134, South Korea | 54980727300; 55455771300; 57014428600; 57211278402; 56286036900 | wooseok@cnu.ac.kr; | Journal of the Korea Concrete Institute | 1229-5515 | 33 | 1 | 0.08 | 2025-07-30 | 1 | Alkali-silica reaction; Concrete median barrier; Deterioration; Maintenance; Numerical simulation | Korean | Final | 2021 | 10.4334/jkci.2021.33.1.011 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Performance Evaluations of TCP in 5G mmWave Cellular Network | The wide bandwidth of the millimeter-wave (mmWave) band can provide multi-gigabit per second data rate services to meet the high demand for fast data rates. However, high bandwidth mmWave channels suffer from very large and frequent degradation of the received signal quality due to blocking. These highly dynamic channel conditions can significantly degrade the end-to-end performance of TCP, the most widely used transport layer protocol. In this paper, we examined the problems that TCP may experience in 5G mmWave cellular networks and conducted various experiments related to TCP using mmWave links. Experiments confirmed that the large variability of the mmWave band causes excessive queuing delay, and the link-layer retransmission mechanism applied to the cellular network serves to hide the status of the radio channel from the upper layer TCP, thereby further accelerating queue creation. Active queue management policy can reduced queuing delay, but end-to-end throughput is reduced due to low buffer utilization. Therefore, a new congestion control algorithm that can fully utilize the available capacity of the mmWave link is needed, and a way to lower the delay through cooperation with the queue management policy should be sought. © 2021, Korean Institute of Communications and Information Sciences.

| ○ | Article | Performance of Railway Roadbed Reinforced by Acrylate in Laboratory Experiment | This paper deals with the reinforcement performance of acrylate for reinforcing the settled railway roadbed. Concrete tracks have the advantage of reducing track maintenance costs and high resistance to track destruction. However, roadbed settlement is occurring in some construction sections, and the safety of railways is a serious concern because of difficulties in maintenance. Currently, maintenance through the track restoration method is being carried out in Korea as a way of roadbed settlement in concrete tracks, but continuous re-settlement can occur because the roadbed itself cannot be reinforced, and there are very few cases of reinforcement of railway roadbeds and field application. So the development of reinforcement materials and construction methods to reinforce railway roadbeds is required. Therefore, in this paper, acrylate was selected as reinforcement material for railway roadbed, and the reinforcement performance of acrylate was analyzed through experiment. As a result, it was analyzed that the acrylate can penetrate into a permeability coefficient of 1x10(-4) cm/sec, and secure uniaxial compression strength of 0.5 MPa/30min or more and stiffness of 80 MPa or more. | Yoon, Hwan-Hee; Son, Min; Kim, Jin-Hwan; Kim, Dong-Hyun; Kim, Byung-Hyun; Jung, Hyuk-Sang | Dongyang Univ, Dept Railrd Construct & Safety Engn, 145 Dongyangdae Ro, Yeongju Si 36040, Gyeongsangbuk D, South Korea; Korea Int Univ Ferghana, Dept Civil Engn, 55 B Uy,A Navoiy St, Fargona City 150100, Fargona Region, Uzbekistan; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, 80 Daehakro Ro, Daegu 41566, South Korea | Kim, Byung-Hyun/ABI-4964-2020 | yoricom@dyu.ac.kr; | JOURNAL OF THE KOREAN GEOSYNTHETIC SOCIETY | J KOREAN GEOSYNTH SO | 2508-2876 | 2287-9528 | 20 | 1 | ESCI | ENGINEERING, GEOLOGICAL | 2021 | N/A | 0 | Railway roadbed; Roadbed reinforcement; Acrylate; Chemical grouting | Korean | 2021 | 2021-03 | 10.12814/jkgss.2021.20.1.009 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Phenotype and ploidy evaluation of colchicine-induced Echeveria ‘Peerless’ | Objective: The study was conducted to evaluate the phenotype and ploidy level of colchicine-induced Echeveria ‘Peerless’. Methods: Leaf cuttings of Echeveria ‘Peerless’ were treated with different concentrations of colchicine (0.2%, 0.4%, 0.6%, 0.8%, and 1.0%) for different durations (3, 6, 9, and 12 h). The survival and mutation rates following various treatments were determined, and the phenotypic characteristics were evaluated 12 months after the treatment. Putative succulent plants were subjected to stomatal evaluation and flow cytometry to confirm the ploidy level. Results: Colchicine treatment produced more compact mutant plants with thicker and shorter leaves with a redder tone. In addition, colchicine-induced mutant plants showed obviously broader leaf apices than control plants. Treatment with 0.2–0.6% colchicine for 3–12 h achieved a survival rate of over 50% while producing the required effects. Moreover, treatment with 0.2–0.6% colchicine for 3–12 h or with 0.8% colchicine for 3–9 h successfully produced diploid–tetraploid mixoploids, which explains the altered phenotype, increased stomatal size, and decreased stomatal density of the succulents. Conclusions: This study established an effective method to induce polyploidy in Echeveria ‘Peerless’, which can be used to create novel genetic sources for developing and breeding new cultivars. © 2020, Korean Society of Environmental Risk Assessment and Health Science. | Cabahug, Raisa Aone M.; Khanh, Ha Tran Thi My; Lim, Ki-Byung; Hwang, Yoon-Jung | Chromosome Research Institute, Sahmyook University, Seoul, 01795, South Korea; Department of Convergence Science, Sahmyook University, Seoul, 01795, South Korea; Department of Horticulture Science, Kyungpook National University Daegu, Daegu, 41566, South Korea; Department of Convergence Science, Sahmyook University, Seoul, 01795, South Korea | 57211922965; 57218586992; 7403175915; 50061210800 | hyj@syu.ac.kr; | Toxicology and Environmental Health Sciences | TOXICOL ENV HEALTH | 2005-9752 | 2233-7784 | 13 | 1 | ESCI | ENVIRONMENTAL SCIENCES;TOXICOLOGY | 2021 | N/A | 0.42 | 2025-07-30 | 8 | Chemical mutagenesis; Colchicine; Leaf cuttings; Ornamental plants; Succulents | colchicine; Article; breeding; chromosome doubling; chromosome segregation; Chrysanthemum; crop improvement; flow cytometry; Gladiolus; Glycyrrhiza; humidity; LD50; Lilium longiflorum; mortality; mutation rate; nonhuman; ornamental plant; Pelargonium; phenotype; plant growth; plant height; plant leaf; ploidy; polyploidy; safflower; spectrophotometry; succulent; survival rate; tetraploidy; upregulation | English | Final | 2021 | 10.1007/s13530-020-00069-z | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Photocontrollable Resistivity Change in Nanoparticle-Doped Liquid Crystal Alignment Layer: Voltage Holding and Discharging Properties of Fringe-Field Switching Liquid Crystal Modes | In liquid crystal (LC) displays, deriving an optimum resistance level of an LC alignment polyimide (PI) layer is important because of the trade-off between the voltage holding and surface-discharging properties. In particular, to apply a power-saving low-frequency operation scheme to fringe-field switching (FFS) LC modes with negative dielectric LC (n-LC), delicate material engineering is required to avoid surface-charge-dependent image flickering and sticking problems, which severely degrade with lowering operation frequency. Therefore, this paper proposes a photocontrolled variable-resistivity PI layer in order to systematically investigate the voltage holding and discharging properties of the FFS n-LC modes, according to the PI resistivity (rho) levels. By doping fullerene into the high-rho PI as the photoexcited charge-generating nanoparticles, the rho levels of the PI were continuously controllable with a wide tunable range (0.95 x 10(15) omega center dot cm to 5.36 x 10(13) omega center dot cm) through Ar laser irradiation under the same LC and LC alignment conditions. The frequency-dependent voltage holding and discharge behaviors were analyzed with photocontrolled rho variation. Thus, the proposed experimental scheme is a feasible approach in PI engineering for a power-saving low-frequency FFS n-LC mode without the image flickering and image sticking issues. | Ko, Jeong-Hoon; Choi, Jun-Chan; Lee, Dong-Jin; Lee, Jae-Won; Kim, Hak-Rin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; LG Display Co Ltd, Paju 10845, Gyeounggi Do, South Korea; Kyungpook Natl Univ, Dept Sensor & Display Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Kim, Hak-Rin/T-1897-2019 | 57203225528; 57033068900; 57207418685; 58377059800; 7410124944 | ulhosim2@knu.ac.kr;jcchoi@knu.ac.kr;dongjina@lgdisplay.com;mekaroid@knu.ac.kr;rineey@knu.ac.kr; | CRYSTALS | 2073-4352 | 11 | 3 | 0.23 | 2025-07-30 | 4 | 4 | photocontrolled resistivity; liquid crystal alignment polyimide layer; voltage holding property; discharging property; fringe-field switching liquid crystal mode | Discharging property; Fringe-field switching liquid crystal mode; Liquid crystal alignment polyimide layer; Photocontrolled resistivity; Voltage holding property | English | 2021 | 2021-03 | 10.3390/cryst11030268 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Photoluminescence of amorphous carbon nitride (a-C:N) thin films grown by facing target sputtering method | In this study, amorphous carbon nitride (a-C:N) thin films were deposited on glass substrates by using a facing target sputtering technique, and the effects of growth temperature were investigated. The deposition rate of the films gradually increased from 1.6 nm/min to 5 nm/min with increasing growth temperature. Emission peaks in the PL spectra of a-C:N films were found at 2.6 eV (green), 3.0 eV (blue), and 3.2 eV (UV). The blue and the UV emissions exhibited an inverse relationship with increasing growth temperature. The ratio of [N]/[C+N] increased from 11% to 15% with increasing to growth temperatures, and this implied an increase of C-N bonding in the films. As the growth temperature was increased, double-bonded nitrogen (Nd, =N-) and triple-bonded nitrogen (Nt, -N<) showed an inverse relationship, and the ratio of [Nt]/[Nd + Nt] increased from 80% to 93%. This tendency was similar to the relationship between the blue and the UV emissions according to growth temperature. Thus, the ratio of Nt and the intensity of UV emission are thought to be closely related, and these changes are thought to play a major role in determining the optoelectronic properties of the films. © This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. | Kim, Hong Tak; Lee, Hyeong-Rag; Lee, Sung-Youp | Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea | 7410138212; 7501484844; 14830491400 | physylee@knu.ac.kr; | New Physics: Sae Mulli | 0374-4914 | 71 | 5 | 0 | 2025-07-30 | 0 | Amorphous carbon nitride; Facing target sputtering; Photoluminescence | Korean | Final | 2021 | 10.3938/npsm.71.433 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Phylogeny and Morphology ofSarcopodium terrigenum sp. Nov., A Novel Fungal Species Isolated from Soil in Korea | A fungal strain was isolated from a soil sample collected in Korea and designated as YW23-8. Based on a sequence analysis of the internal transcribed spacer (ITS) regions, the isolate was assigned to the genus Sarcopodium. Moreover, a phylogenetic analysis based on the concatenated nucleotide sequences of the ITS regions and the large subunit of the nuclear ribosomal RNA (LSU) gene showed that the strain YW23-8 occupies a distinct phylogenetic position within Sarcopodium. The isolate had significant differences from its closest neighbors, S. circinosetiferum, S. circinatum, S. macalpinei, and S. vanillae. Morphological features such as different conidial structures, the absence of septation in conidia, and the presence of milky white watery droplets along with the results of the phylogenetic analysis clearly distinguish YW23-8 from the closest Sarcopodium species. We therefore conclude that strain YW23-8 represents a novel species of the genus Sarcopodium for which we propose the name Sarcopodium terrigenum. © 2021 THE KOREAN SOCIETY OF MYCOLOGY. | Elderiny, Nabil Salah; Das, Kallol; Lee, Seung-Yeol; Jung, Hee-Young | School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea, Institute of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea, Institute of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea | 57195424553; 57203751520; 56106499600; 7403029383 | heeyoung@knu.ac.kr; | Korean Journal of Mycology | 0253-651X | 49 | 2 | 0.1 | 2025-07-30 | 1 | Nectriaceae; Phylogeny; Sarcopodium; Taxonomy | English | Final | 2021 | 10.4489/kjm.20210017 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Physicochemical Characteristics and Microbial Communities in Gochujang, a Traditional Korean Fermented Hot Pepper Paste | Gochujang is a Korean fermented hot pepper paste beneficial to human health by providing various nutrients. In this study, its physicochemical characteristics were identified, and its microbial communities were analyzed by high-throughput sequencing. The interrelationship between physicochemical characteristics and microbial composition was investigated to reveal the properties of gochujang before and after fermentation. After fermentation, all samples showed decreased salt concentration, pH, and reducing sugar content, while the acidity and amino-type nitrogen increased. The water content, salt concentration, amino-type nitrogen, and reducing sugar differed according to the batches of samples. Bacillus, Aerosakkonema, and Enterococcus were identified as the predominant bacterial genera. Furthermore, Aerosakkonema was the most abundant genus before fermentation; however, it was replaced by Bacillus as it decreased after fermentation. For the fungi, Aspergillus dominated before fermentation, whereas Zygosaccharomyces and Millerozyma dominated after fermentation. The high level of amino-type nitrogen in gochujang was related to the relative abundance of B. haynesii/B. licheniformis before fermentation. Additionally, the high abundance of Z. rouxii after fermentation was related to the flavor of gochujang. This comprehensive analysis of the microbial community associated with the physicochemical properties of gochujang could help in understanding the factors affecting the quality of the product. | Ryu, Jung-A; Kim, Eiseul; Kim, Mi-Ju; Lee, Shinyoung; Yoon, Sung-Ran; Ryu, Jung-gi; Kim, Hae-Yeong | Gyeongsangbuk Do Agr Res & Extens Serv, Daegu, South Korea; Kyungpook Natl Univ, Dept Hort, Daegu, South Korea; Kyung Hee Univ, Inst Life Sci & Resources, Yongin, South Korea; Kyung Hee Univ, Dept Food Sci & Biotechnol, Yongin, South Korea | Kim, Hae-Yeong/S-1685-2017; Kim, Juhee/KFS-3069-2024 | 57216744726; 56160562000; 56161913500; 57200426356; 24400410500; 59877800800; 7410133624 | hykim@khu.ac.kr; | FRONTIERS IN MICROBIOLOGY | 1664-302X | 11 | 2.02 | 2025-07-30 | 28 | 30 | gochujang; physicochemical characteristics; high-throughput sequencing; microbial community; Bacillus; Zygosaccharomyces | METABOLITE CHANGES; BIOGENIC-AMINES; SAUCE; SUCCESSION; DYNAMICS; NITROGEN; MEJU | Bacillus; gochujang; high-throughput sequencing; microbial community; physicochemical characteristics; Zygosaccharomyces | amino type nitrogen; internal transcribed spacer; nitrogen; reducing sugar; RNA 16S; sodium chloride; sugar; unclassified drug; acidity; Aerosakkonema; Article; Aspergillus; Aspergillus oryzae; Bacillus; Bacillus cereus; Bacillus licheniformis; budding yeast; colony forming unit; color; controlled study; Enterobacter; Enterococcus; fermentation; fermented product; fungal community; Fusarium; gochujang; hierarchical clustering; high throughput sequencing; lactic acid bacterium; microbial community; Millerozyma; nonhuman; Oscillatoriales; osmosis; pH; physical chemistry; principal coordinate analysis; species richness; titrimetry; viable cell count; water content; yeast; Zygosaccharomyces; Zygosaccharomyces rouxii | English | 2021 | 2021-01-18 | 10.3389/fmicb.2020.620478 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Physicochemical Modulation of Nanometer-Thick Etalon Films for Liquid-Sensitive Color Display with Full-Color Spectrum Generation | Light-matter interactions based on noble metal nanostructures have received continued attention for their tremendous potential for the discovery of basic science as well as their application in practical devices driven by their unique optical characteristics. However, constructing such nanostructured platforms requires relatively expensive and complicated fabrication processes to produce a wide range of colors in the visible region. In this paper, we propose a simple nanoscale Fabry-Perot film capable of providing full-color coverage in the visible region with a high level of color tunability through engineering the geometries of the constituent layers. Specifically, the thicknesses and filling-fractions of each layer were precisely tailored to allow for fine color tuning together with theoretical modeling to set up a standard guideline of structural colors depending on such physical variables. The physicochemical property-dependent coloration was demonstrated via the simple nanometer-thick Fabry-Perot stack, which was further applied to functional mimicry of environmental sensitive optical camouflage. | Jeong, Hee-Dong; Lee, Jongsu; Yu, Eui-Sang; Kim, Taehyun; Kim, In Soo; Lee, Sin-Doo; Ryu, Yong-Sang; Lee, Seung-Yeol | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Korea Inst Sci & Technol, Sensor Syst Res Ctr, Seoul 02792, South Korea; Seoul Natl Univ, Dept Elect & Comp Engn, Seoul 08826, South Korea; Korea Univ, Dept Micro Nano Syst, Seoul 02841, South Korea; Korea Inst Sci & Technol, Nanophoton Res Ctr, Seoul 02792, South Korea | ; Ryu, Yong-Sang/AAI-3948-2020; Lee, Sin-Hyung/ABD-6425-2022; Yu, Eui-Sang/GVR-7972-2022; Lee, Seungwoo/U-8056-2017; Kim, Taek-Soo/C-1843-2011 | 57193707766; 58175758800; 56297930000; 59783064600; 56720626700; 34974364800; 55229727000; 55881869300 | ysry82@kist.re.kr;seungyeol@knu.ac.kr;ysryu82@kist.re.kr; | ACS APPLIED NANO MATERIALS | 2574-0970 | 4 | 1 | 0.23 | 2025-07-30 | 5 | 5 | structural color; metamaterials; thin-film resonator; color tuning; optical camouflage; nanostructured sensor | PHYSICS | color tuning; metamaterials; nanostructured sensor; optical camouflage; structural color; thin-film resonator | Fabry-Perot interferometers; Physicochemical properties; Precious metals; Fabrication process; Light-matter interactions; Metal nanostructure; Optical camouflages; Optical characteristics; Physical variables; Standard guidelines; Theoretical modeling; Color | English | 2021 | 2021-01-22 | 10.1021/acsanm.0c02746 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | Physicochemical properties and antioxidant activities of ginger (Zingiber officinale Roscoe) slices according to temperature and duration of hot water treatment | This study was conducted to determine the optimal hydrothermal pretreatment conditions for manufacturing processed ginger products. Ginger slices heated at different temperatures (60-100℃ for 1 h) for varying durations (1-5 h at 80℃) were compared in terms of their physiochemical properties, antioxidant activities, and functional compound contents. The pH and soluble solid content decreased with increasing hydrothermal treatment temperature. Browning occurred at temperatures > 80℃. The 2,2-diphenyl-1-picrahydrazyl and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging were highest after heating at 80℃ for 1 h, and the total phenolic compound content showed a similar trend. As the hydrothermal treatment temperature and duration increased, the 6-gingerol content decreased and the 6-shogaol content generally increased. Based on sensory testing of ginger jeonggwa (with sugar syrup) prepared using hot water-treated ginger slices, the optimal hot water treatments were conducted at 70 and 80℃ for 1 h, with no significant difference between these temperatures in terms of smell, taste, and texture. Therefore, hydrothermal treatment of ginger at 70-80℃ for 1 h was a suitable to improve the functionality and antioxidant ability while maintaining the sensory quality. Therefore, this may be used in the production of processed ginger. © The Korean Society of Food Preservation. | Choi, Ji-Young; Lee, Yeong-Min; Kim, Jiyoon; Kim, Jungsoo; Jeong, Saeul; Park, Sanghyeok; Kim, Minhyun; Moon, Kwang-Deog | Research Group of Consumer Safety, Korea Food Research Institute, Wanju, 55365, South Korea; Health and Environment Institute of Daegu, Daegu, 42183, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea | 57219113098; 57188840329; 57208110209; 57211108486; 57219605598; 57226601564; 57226597969; 55999192900 | kdmoon@knu.ac.kr; | Korean Journal of Food Preservation | 1738-7248 | 28 | 6 | 0.08 | 2025-07-30 | 1 | 6-shogaol; Antioxidant capacities; Ginger slice; Hydrothermal treatment; Optimal pretreatment condition | English | Final | 2021 | 10.11002/kjfp.2021.28.6.716 | 바로가기 | 바로가기 |
