| ○ | ○ | Article | Measurement of ⁵⁹Co(n, x) reaction cross sections with the fast neutrons based on the ⁹Be(p, n) reaction * | The cross sections of the Co-59(n, x) reaction in the average energy range of 15.2-37.2 MeV were measured using activation and an off-line gamma-ray spectrometric technique. The neutrons were generated from the Be-9(p, n) reaction with proton beam energies of 25-45 MeV at the MC-50 Cyclotron facility of the Korean Institute of Radiological and Medical Sciences (KIRAMS). Theoretical calculations of neutron-induced reactions on Co-59 were performed using the nuclear model code TALYS-1.9. The results for the Co-59(n, x) reactions were compared with the theoretical values obtained using TALYS-1.9 and the literature data provided in EXFOR and the TENDL 2019 nuclear data library. The theoretical values obtained using TALYS-1.9 with adjusted parameters are comparable to the experimental data. The measured reaction cross sections of a few radionuclides are new, and the others are comparable to the literature data, and thus, they can strengthen the database. The present study on cross sections leads to useful insight into the mechanisms of Co-59(n, x) reactions. | Zaman, Muhammad; Nadeem, Muhammad; Sahid, Muhammad; Kim, Kwangsoo; Kim, Guinyun; Nguyen Thi Hien | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Kyungpook Natl Univ, Ctr High Energy Phys, Daegu 41566, South Korea; Vietnam Acad Sci & Technol, Inst Phys, 10 Dao Tan, Hanoi, Vietnam | Zaman, Hafiz/ITT-3200-2023; Nadeem, Muhammad/HKV-5114-2023 | 7102724138; 56730154200; 55846094000; 36137214700; 35313854400; 56469044600 | gnkim@knu.ac.kr; | CHINESE PHYSICS C | CHINESE PHYS C | 1674-1137 | 2058-6132 | 45 | 4 | SCIE | PHYSICS, NUCLEAR;PHYSICS, PARTICLES & FIELDS | 2021 | 2.944 | 39.5 | 0.08 | 2025-07-30 | 1 | 1 | Co-59(n; x) reaction cross sections; average neutron energy of 15; 2-37; 2 MeV; off-line γ -ray spectrometry; MCNPX 2; 6; 0 simulation; TALYS-1; 9 | EXCITATION-FUNCTIONS; ACTIVATION EXPERIMENTS; THRESHOLD REACTIONS; CO-59(N,P)FE-59; RATIOS; MODEL; FIELD; N,2N; NI; CO | <sup>59</sup>Co(n; average neutron energy of 15.2-37.2 MeV; MCNPX 2.6.0 simulation; off-line γ-ray spectrometry; TALYS-1.9; x) reaction cross sections | English | 2021 | 2021-04 | 10.1088/1674-1137/abe196 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Measurements of ⁿatCd(γ, x) reaction cross sections and isomer ratio of ¹¹⁵m,gCd with the bremsstrahlung end-point energies of 50 and 60 MeV | The flux-weighted average cross sections of Cd-nat(gamma, xn)Cd-115g,Cd-m,Cd-111m,Cd-109,Cd-107,Cd-105,Cd-104 and Cd-nat(gamma, x)Ag-113g,Ag-112,Ag-111g,Ag-110m reactions were measured at the bremsstrahlung end-point energies of 50 and 60 MeV. The activation and off-line gamma-ray spectrometric technique was carried out using the 100 MeV electron linear accelerator at the Pohang Accelerator Laboratory, Korea. The Cd-nat(gamma, xn) reaction cross sections as a function of photon energy were theoretically calculated using the TALYS-1.95 and the EMPIRE-3.2 Malta codes. Then, the flux-weighted average cross sections were obtained from the theoretical values of mono-energetic photons. These values were compared with the flux-weighted values from the present study and were found to be in general agreement. The measured experimental reaction cross-sections and integral yields were described for cadmium and silver isotopes in the Cd-nat(gamma, xn)Cd-115g,Cd-m,Cd-111m,Cd-109,Cd-107,Cd-105,Cd-104 and Cd-nat(gamma, x)Ag-113g,Ag-112,Ag-111g,Ag-110m reactions. The isomeric yield ratio (IR) of Cd-115g,Cd-m in the Cd-nat(gamma, xn) reaction was determined for the two bremsstrahlung end-point energies. The measured isomeric yield ratios of Cd-115g,Cd-m in the Cd-nat(gamma, xn) reaction were also compared with the theoretical values of the nuclear model codes and previously published literature data of the Cd-116(gamma, n) and Cd-116(n, 2n) reactions. It was found that the IR value increases with increasing projectile energy, which demonstrates the characteristic of excitation energy. However, the higher IR value of Cd-115g,Cd-m in the Cd-116(n, 2n) reaction compared to that in the Cd-116(gamma, n) reaction indicates the role of compound nuclear spin alongside excitation energy. | Nadeem, Muhammad; Rahman, Md Shakilur; Shahid, Muhammad; Kim, Guinyun; Naik, Haladhara; Nguyen Thi Hien | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Bangladesh Atom Energy Commiss, Inst Nucl Sci & Technol, Dhaka, Bangladesh; Bhabha Atom Res Ctr, Radiochem Div, Mumbai 400085, Maharashtra, India | Nadeem, Muhammad/HKV-5114-2023; Rahman, Md saidur/HHY-9727-2022; Shahid, Muhammad/AAE-9424-2020 | 56730154200; 55457938000; 57220603664; 35313854400; 7005890232; 59638495100 | gnkim@knu.ac.kr; | CHINESE PHYSICS C | CHINESE PHYS C | 1674-1137 | 2058-6132 | 45 | 12 | SCIE | PHYSICS, NUCLEAR;PHYSICS, PARTICLES & FIELDS | 2021 | 2.944 | 39.5 | 0.15 | 2025-07-30 | 3 | 2 | Cd-nat(gamma, xn) reaction cross sections; isomer yield ratio of Cd-115g,Cd-m; off-line gamma-ray spectrometric technique; TALYS-1.95; TENDL-2019; EMPIRE-3.2 Malta | YIELD RATIOS; EXCITATION | <sup>nat</sup>Cd(?, xn) reaction cross sections; EMPIRE-3.2 Malta; isomer yield ratio of <sup>115g,m</sup>Cd; off-line ?-ray spectrometric technique; TALYS-1.95; TENDL-2019 | English | 2021 | 2021-12 | 10.1088/1674-1137/ac256b | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Accuracy of genotype imputation based on reference population size and marker density in Hanwoo cattle | Recently, the cattle genome sequence has been completed, followed by developing a com-mercial single nucleotide polymorphism (SNP) chip panel in the animal genome industry. In order to increase statistical power for detecting quantitative trait locus (QTL), a number of ani-mals should be genotyped. However, a high-density chip for many animals would be increas-ing the genotyping cost. Therefore, statistical inference of genotype imputation (low-density chip to high-density) will be useful in the animal industry. The purpose of this study is to inves-tigate the effect of the reference population size and marker density on the imputation accu-racy and to suggest the appropriate number of reference population sets for the imputation in Hanwoo cattle. A total of 3,821 Hanwoo cattle were divided into reference and validation pop-ulations. The reference sets consisted of 50k (38,916) marker data and different population sizes (500, 1,000, 1,500, 2,000, and 3,600). The validation sets consisted of four validation sets (Total 889) and the different marker density (5k [5,000], 10k [10,000], and 15k [15,000]). The accuracy of imputation was calculated by direct comparison of the true genotype and the imputed genotype. In conclusion, when the lowest marker density (5k) was used in the valida-tion set, according to the reference population size, the imputation accuracy was 0.793 to 0.929. On the other hand, when the highest marker density (15k), according to the reference popula-tion size, the imputation accuracy was 0.904 to 0.967. Moreover, the reference population size should be more than 1,000 to obtain at least 88% imputation accuracy in Hanwoo cattle. | Lee, DooHo; Kim, Yeongkuk; Chung, Yoonji; Lee, Dongjae; Seo, Dongwon; Choi, Tae Jeong; Lim, Dajeong; Yoon, Duhak; Lee, Seung Hwan | Chungnam Natl Univ, Div Anim & Dairy Sci, Daejeon 34134, South Korea; Natl Inst Anim Sci, Cheonan 31000, South Korea; Natl Inst Anim Sci, Anim Genom & Bioinformat Div, Wonju 55365, South Korea; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea | ; Lee, SeungHwan/LUY-2745-2024 | 57221245344; 57202643847; 57216463601; 57406504200; 55887111800; 55270660400; 8550517900; 7202875754; 59475424700 | slee46@cnu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 6 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.12 | 2025-07-30 | 5 | 1 | Single nucleotide polymorphism (SNP); Imputation; Hanwoo cattle; Reference population size; Marker density | WHOLE-GENOME ASSOCIATION; WIDE ASSOCIATION; SELECTION; PREDICTION | Hanwoo cattle; Imputation; Marker density; Reference population size; Single nucleotide polymorphism (SNP) | English | 2021 | 2021 | 10.5187/jast.2021.e117 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Alteration of the gut microbiota in post-weaned calves following recovery from bovine coronavirus-mediated diarrhea | Bovine coronavirus (BCoV) is associated with severe diarrhea, dehydration, and depression, which result in significant economic damages in the dairy and beef cattle industries worldwide. However, differences in the gut microbiota structure and their correlations with differing physiological parameters between BCoV-infected calves with diarrhea and recovered calves are not well understood. In this study, fecal specimens were collected from 10 postweaned calves, before and after 2 months of fluid therapy, and the samples were used for microbiota analysis. Following recovery, the alpha-diversity profiles (observed operational taxonomic units [OTUs], and Chao1, Shannon, and Simpson indices) changed significantly when compared with those of calves with diarrhea. Beta-diversity analysis exhibited significant differences in gut microbiota compositions between calves with diarrhea and those in the recovered state. The abundances of eight phyla and thirteen genera in feces changed markedly after restoration of BCoV diarrhea. In addition, our correlation study clearly revealed that increased abundances of the genera Caproiciproducens, Pseudoflavonifractor, and Oscillibacter negatively correlated with serum glucose, and phosphorus levels, but positively correlated with serum chloride in calves with diarrhea, whereas increased abundances of the genera Peptostreptococcaceae;Clostridium (Clostridium cluster XI), Intestinibacter, Cellulosilyticum, Ruminococcus, Romboutsia, Paeniclostridium, Clostridiaceae;Clostridium and Turicibacter in recovered calves showed the opposite pattern. These results suggest that structural changes of the gut microbiota after recovery from BCoV infection correlate with changes in physiological parameters. In conclusion, our data provide evidence of gut microbiota-composition changes and their correlations with the physical profiles of post-weaned calves, before and after fluid therapy for BCoV-related diarrhea. | Kwon, Min-Sung; Jo, Hee Eun; Lee, Jieun; Choi, Kyoung-Seong; Yu, Dohyeon; Oh, Yeon-su; Park, Jinho; Choi, Hak-Jong | World Inst Kimchi, Res & Dev Div, Gwangju 61755, South Korea; Chonnam Natl Univ, Med Sch, Dept Microbiol, Gwangju 61468, South Korea; Kyungpook Natl Univ, Coll Ecol & Environm Sci, Sangju 37224, South Korea; Gyeongsang Natl Univ, Coll Vet Med, Jinju 52828, South Korea; Kangwon Natl Univ, Coll Vet Med, Chunchon 24341, South Korea; Kangwon Natl Univ, Inst Vet Sci, Chunchon 24341, South Korea; Jeonbuk Natl Univ, Coll Vet Med, Iksan 54596, South Korea | ; Choi, Hak-Jong/I-5640-2019 | 57217109873; 57203386534; 56394021100; 7403949556; 14623495400; 57188664571; 8730126700; 8415034400 | jpark@jbnu.ac.kr;hjchoi@wikim.re.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 1 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 1.44 | 2025-07-30 | 15 | 14 | CALF DIARRHEA; DISEASE; FLUID | Bovine coronavirus; Gut microbiota; Physiological parameters; Post-weaned calf | English | 2021 | 2021 | 10.5187/jast.2021.e20 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Collaborative Cloud and Edge Mobile Computing in C-RAN Systems With Minimal End-to-End Latency | Mobile cloud and edge computing protocols make it possible to offer computationally heavy applications to mobile devices via computational offloading from devices to nearby edge servers or more powerful, but remote, cloud servers. Previous work assumed that computational tasks can be fractionally offloaded at both cloud processor (CP) and at a local edge node (EN) within a conventional Distributed Radio Access Network (D-RAN) that relies on non-cooperative ENs equipped with one-way uplink fronthaul connection to the cloud. In this paper, we propose to integrate collaborative fractional computing across CP and ENs within a Cloud RAN (C-RAN) architecture with finite-capacity two-way fronthaul links. Accordingly, tasks offloaded by a mobile device can be partially carried out at an EN and the CP, with multiple ENs communicating with a common CP to exchange data and computational outcomes while allowing for centralized precoding and decoding. Unlike prior work, we investigate joint optimization of computing and communication resources, including wireless and fronthaul segments, to minimize the end-to-end latency by accounting for a two-way uplink and downlink transmission. The problem is tackled by using fractional programming (FP) and matrix FP. Extensive numerical results validate the performance gain of the proposed architecture as compared to the previously studied D-RAN solution. | Park, Seok-Hwan; Jeong, Seongah; Na, Jinyeop; Simeone, Osvaldo; Shamai, Shlomo | Jeonbuk Natl Univ, Div Elect Engn, Jeonju 54896, South Korea; Jeonbuk Natl Univ, Future Semicond Convergence Technol Res Ctr, Jeonju 54896, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 14566, South Korea; Korea Adv Inst Sci & Technol, Dept Elect Engn, Daejeon 34141, South Korea; Kings Coll London, Kings Commun Learning & Informat Proc Kclip Lab, London WC2R 2LS, England; Kings Coll London, Ctr Telecommun Res, Dept Engn, London WC2R 2LS, England; Technion, Dept Elect & Comp Engn, IL-3200003 Haifa, Israel | Jeong, Seongah/ABW-7285-2022; Jeong, Seongah/I-2863-2017; Simeone, Osvaldo/Q-1673-2016 | 27867920900; 55210226900; 57202050105; 23993347300; 35564142000 | seokhwan@jbnu.ac.kr;seongah@knu.ac.kr;wlsduq37@kaist.ac.kr;osvaldo.simeone@kcl.ac.uk;sshlomo@ee.technion.ac.il; | IEEE TRANSACTIONS ON SIGNAL AND INFORMATION PROCESSING OVER NETWORKS | IEEE T SIGNAL INF PR | 2373-776X | 7 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS | 2021 | 3.301 | 39.7 | 1.22 | 2025-07-30 | 19 | 21 | Task analysis; Uplink; Collaboration; Computer architecture; Downlink; Optimization; Edge computing; Mobile cloud computing; edge computing; C-RAN; constrained fronthaul; end-to-end latency minimization; (matrix) fractional programming | DISTRIBUTED METHODS; JOINT OPTIMIZATION; RADIO; ACCESS; NETWORKS; INTERFERENCE; PARALLEL; DELAY; USERS; 5G | (matrix) fractional programming; C-RAN; constrained fronthaul; edge computing; end-to-end latency minimization; Mobile cloud computing | Mathematical programming; Mobile telecommunication systems; Network architecture; Radio access networks; Communication resources; Computational task; Downlink transmissions; End to end latencies; Fractional programming; Joint optimization; Numerical results; Proposed architectures; Mobile cloud computing | English | 2021 | 2021 | 10.1109/tsipn.2021.3070712 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effects of intravenous multiple busulfan injection on suppression of endogenous spermatogenesis in recipient stallion testes | Preparation of recipient stallions is critical step to produce donor spermatogonial stem cell (SSC) derived sperm using transplantation technique. This study was conducted to evaluate the effects of intravenous busulfan infusion on germ cell depletion, semen production, and libido in stallions. Six Thoroughbred stallions were separated into two treatment groups: 1) a multiple low-dose (2.5 mg/kg bw for the first 4 weeks and 5 mg/kg bw for the 5th week); and 2) control group treated with PBS. Testicular samples were obtained at 11 weeks and classified into three different patterns of spermatogenesis, such as normal, Sertoli cell only, and destroyed. Semen collection and libido experiments were performed 1 week before treatment, and 4 and 8 weeks after treatment. For the sperm analysis, total spermatozoa and motility were measured using a light microscope with a motility analyzing system. In the multiple lowdose group, the numbers of tubules categorized as Sertoli cell only were significantly higher than those in the control as well as the total population and total/progressive motility of sperm were significantly decreased 8 weeks after the start of the treatment. The sperm production and motility in the multiple low-dose group appears to be reduced, while libido was maintained. In conclusion, multiple administration of 2.5 mg/kg bw busulfan depletes endogenous germ cells in the stallion recipients for SSC transplantation. | Jung, Heejun; Yoon, Minjung | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Horse Compan & Wild Anim Sci, Sangju 37224, South Korea | 56374279800; 22137296500 | mjyoon@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 5 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.6 | 2025-07-30 | 4 | 5 | Busulfan; Germ cell depletion; Sperm; Stallion | STEM-CELL TRANSPLANTATION; GERM-CELL; SERTOLI-CELLS; MOUSE TESTIS; CRYOPRESERVATION; DIFFERENTIATION; PROLIFERATION; FERTILITY; DIVISION; GLYCEROL | Busulfan; Germ cell depletion; Sperm; Stallion | English | 2021 | 2021 | 10.5187/jast.2021.e80 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Evaluation of pig behavior changes related to temperature, relative humidity, volatile organic compounds, and illuminance | The objective of this study was evaluation of pig behavior changes related to temperature, relative humidity, volatile organic compounds (VOCs), and illuminance. A total of 24 growing pigs ([Yorkshire x Landrace] x Duroc) were used in the experiment. A sensor was installed at a height of 0.5 m in the center of the pig house. In experiment 1, temperature was changed every four days to 18 degrees C (T1), 22 degrees C (T2), 26 degrees C (T3), and then 30 degrees C (T4). In experiment 2, relative humidity was adjusted to 45% (low humidity [LH]), 60% (middle humidity [MH]), and then 75% (high humidity [HH]) for four days. In experiment 3, after cleaning the pig house just before experiment, only minimal ventilation was provided. VOCs and pig behaviors were observed for 7 days without cleaning the pig house. In experiment 4, three light bulbs of 40 W (470 lumens / 45 lx; low illuminance [LI]), 75 W (1,055 lumens / 103 lx; middle illuminance [MI]), and 100 W (1,521 lumens / 146 lx; high illuminance [HI]) were used for four days each. Pig behavior analysis was performed for following criteria : Feed intake, Standing, Lying, Sitting, Drink water, Rooting, Posture transition (lying-standing), Posture transition (standing-lying), Wallowing, and Biting. In experiment 1, feed intake time was lower (p < 0.05) for the T3 than other treatment groups. Standing time was highest (p < 0.05) for the T1 and lowest (p < 0.05) for the T3. Lying time was shorter (p < 0.05) in T1 and T2 compared to T3 and T4. Drinking frequency was higher (p < 0.05) for the T4 than other treatment groups. In experiment 2, the frequency of rooting and wallowing increased (p < 0.05) with increasing humidity. LH showed the lowest (p < 0.05) rooting frequency and HH showed the highest (p 0.05) rooting frequency. In experiment 3, VOCs concentration did not (p 0.05) change pig behavior. In experiment 4, lying time was the longest (p < 0.05) at LI and shortest (p < 0.05) at HI. Therefore, pig behavior is heavily influenced by the environment, especially temperature and humidity. However, correlation between pig behavior to VOCs and illuminance seems to be needed more research. | Kim, Yong Ju; Song, Min Ho; Lee, Sang In; Lee, Ji Hwan; Oh, Han Jin; An, Jae Woo; Chang, Se Yeon; Go, Young; Park, Beom Jun; Jo, Min Seok; Lee, Chang Gyu; Kim, Hyeun Bum; Cho, Jin Ho | Chungbuk Natl Univ, Div Food & Anim Sci, Cheongju 28644, South Korea; Chungnam Natl Univ, Dept Anim Sci & Biotechnol, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, South Korea; Dronic, Daejeon 35240, South Korea; Dankook Univ, Dept Anim Resource & Sci, Cheonan 31116, South Korea | Song, Minho/KHW-1844-2024; OH, HANJIN/IQS-6167-2023; LEE, JIHWAN/LMO-2895-2024; Kim, Hansu/F-5909-2013 | 57196172056; 57200569587; 57203597336; 57203145183; 57194770441; 57226974200; 57228250900; 57227154800; 57218905160; 57227523500; 57219051797; 55784908300; 35228467000 | hbkim@dankook.ac.kr;jinhcho@chungbuk.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 4 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.96 | 2025-07-30 | 12 | 11 | GROWING PIGS | Illuminance; Pig behavior; Relative humidity; Temperature; Volatile organic compounds | English | 2021 | 2021 | 10.5187/jast.2021.e89 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Feeding strategies with total mixed ration and concentrate may improve feed intake and carcass quality of Hanwoo steers | This study examined the impact of using total mixed ration (TMR) and concentrate on feed intake, daily gain, carcass yield grade, and carcass quality grade of Hanwoo steers and its subsequent economic efficiency. Thirty six 7-month-old Hanwoo steers were assigned to one of the four treatment groups, and each group was divided into three repeated pens, with each repeated pen comprising three steers. The treatment groups were: 1) separate feeding with commercial concentrate and forage (namely, SCF) for the entire experimental period; 2) TMR feeding for a growing period followed by SCF for the early and late fattening period (namely, TMRGSCF); 3) TMR feeding for growing and an early fattening period followed by SCF for the late fattening period (namely, TMREFSCF); and 4) TMR feeding for the entire experi-mental period (namely, TMRW). The results showed that the SCF treatment had significantly (p SCF > TMRW. Carcass characteristics, including carcass weight, loin eye muscle area, and carcass yield grade, did not significantly differ among different treatments. However, TMRW treatment, wherein TMR was fed for a long time, showed that the cold carcass weight was less compared with other treatments, but carcass yield grade was higher with thinner backfat. Backfat thickness was in the order of SCF > TMRGSCF > TMREFSCF > TMRW, showing that the thickness reduced with longer TMR feeding (p < 0.05). TMRGSCF, which numerically had a higher carcass quality grade, showed higher economic efficiency, whereas SCF showed low economic efficiency. In con-clusion, it was more feasible to apply TMR strategy in the growing and early fattening period and then SCF for the early or late fattening period to improve carcass yield, quality grade, and economic efficiency. | Lee, Soohyung; Lee, Sang Moo; Lee, Jaehun; Kim, Eun Joong | Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea | ; Kim, Eun Joong/HGF-1639-2022 | 57365946600; 37059282800; 57365795300; 57213620881 | ejkim2011@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 5 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.84 | 2025-07-30 | 8 | 9 | mixed ration (TMR); Hanwoo; Carcass quality; Feed intake; Profits | GROWTH-PERFORMANCE; RUMEN FERMENTATION; BEEF-CATTLE; COMPONENTS; PROTEIN; ENERGY; SYSTEM; NUTRIENTS; BEHAVIOR; SILAGE | Carcass quality; Feed intake; Hanwoo; Profits; Total mixed ration (TMR) | English | 2021 | 2021 | 10.5187/jast.2021.e88 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Improvement of conception rate on Hanwoo; The key hormones and novel estrus detector | Two field experiments were conducted to improve the conception rate of Hanwoo cow. The first experiment aimed to investigate the physiological condition of Hanwoo cows on estrus, including metabolic profiles and body condition score (BCS). The second experiment investigated the effect of a novel estrus detector on the artificial insemination (AI) conception rate for Hanwoo cows. For the first experiment, 80 Hanwoo cows (2.5 +/- 0.10 of parity), approximately one month before estrus, were housed in 16 pens and offered the experimental diets twice daily with free water access. The BCS were recorded, and blood was collected from the jugular veins just before AI. The collected blood was used to measure physiological conditions, such as metabolite and hormone levels. For the second experiment, each cow was equipped with a neck-mounted estrus detector collar, which had a sensor connected through the internet. Approximately one month before estrus, three hundred sixty Hanwoo cows (2.4 +/- 0.21 of parity) were assigned into groups with or without W-Tag collar treatments. The animals were managed the same as in the first experiment. The pregnancy rate reached 55% in the first experiment. The concentration of luteinizing hormone (LH) was higher (p < 0.012; 1.56 vs. 1.08 ng/mL) in cows that were not pregnant (NPG) than in cows that were pregnant (PG) after AI. The BCS and other concentrations of metabolites and hormones in the blood were not different in both NPG and PG cows. The ranges of estrogen, LH, and follicle-stimulating hormone for PG cows were 11.9 to 39.0 pg/mL, < 0.25 to 1.98 ng/mL, and < 0.50 to 0.82 ng/ mL, respectively. In the second experiment, cows with the estrus detector had lower days open (p < 0.001; 78.1 vs. 84.8 d), insemination frequency (p < 0.001; 1.26 vs. 2.52), and return of estrus (p < 0.001; 70.9 vs. 79.1 d) than those in cows without the estrus detector. In conclusion, the present study indicated that lower LH concentration just before AI potentially increased the pregnancy rate of Hanwoo cows. Furthermore, the application of estrus detectors to Hanwoo cows could improve the conception success rate for AI. | Joo, Young Ho; Jeong, Seung Min; Paradhipta, Dimas; Lee, Hyuk Jun; Lee, Seong Shin; Choi, Jeong Seok; Noh, Hyeon Tak; Chang, Hong Hee; Kim, Eun Joong; Kim, Sam Churl | Gyeongsang Natl Univ, Inst Agr & Life Sci, Jinju 52828, South Korea; Gyeongsang Natl Univ, Div Appl Life Sci BK21Four, Jinju 52828, South Korea; Univ Gadjah Made, Dept Anim Nutr & Feed Sci, Yogyakarta 55281, Indonesia; Gyeongsang Natl Univ, Dept Anim Sci, Jinju 52828, South Korea; Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea | ; Kim, Eun Joong/HGF-1639-2022; Lee, Seong Shin/LUP-8584-2024; Hen Hong, Chang/ITT-2813-2023; Paradhipta, Dimas/GQA-4780-2022 | 56102152900; 57406415500; 57204390901; 56012092500; 57210971789; 57222268592; 57222268707; 8953996300; 57213620881; 36835944100 | kimsc@gnu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 6 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.12 | 2025-07-30 | 1 | 2 | Artificial insemination; Conception rate; Estrus detector; Hanwoo cow; Luteinizing hormone | CATTLE; INSEMINATION; TECHNOLOGIES; TIME; COWS | Artificial insemination; Conception rate; Estrus detector; Hanwoo cow; Luteinizing hormone | English | 2021 | 2021 | 10.5187/jast.2021.e122 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | MicroRNA expression profiling during the suckling-to-weaning transition in pigs | Weaning induces physiological changes in intestinal development that affect pigs' growth performance and susceptibility to disease. As a posttranscriptional regulator, microRNAs (miRNAs) regulate cellular homeostasis during intestinal development. We performed small RNA expression profiling in the small intestine of piglets before weaning (BW), 1 week after weaning (1W), and 2 weeks after weaning (2W) to identify weaning-associated differentially expressed miRNAs. We identified 38 differentially expressed miRNAs with varying expression levels among BW, 1W, and 2W. Then, we classified expression patterns of the identified miRNAs into four types. ssc-miR-196a and ssc-miR-451 represent pattern 1, which had an increased expression at 1W and a decreased expression at 2W. ssc-miR-499-5p represents pattern 2, which had an increased expression at 1W and a stable expression at 2W. ssc-miR7135-3p and ssc-miR-144 represent pattern 3, which had a stable expression at 1W and a decreased expression at 2W. Eleven miRNAs (ssc-miR-542-3p, ssc-miR-214, ssc-miR-758, ssc-miR-4331, ssc-miR-105-1, ssc-miR-1285, ssc-miR-10a-5p, ssc-miR-4332, ssc-miR-503, ssc-miR-6782-3p, and ssc-miR-424-5p) represent pattern 4, which had a decreased expression at 1W and a stable expression at 2W. Moreover, we identified 133 candidate targets for miR-196a using a target prediction database. Gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses revealed that the target genes were associated with 19 biological processes, 4 cellular components, 8 molecular functions, and 7 KEGG pathways, including anterior/posterior pattern specification as well as the cancer, PI3K-Akt, MAPK, GnRH, and neurotrophin signaling pathways. These findings suggest that miRNAs regulate the development of the small intestine during the weaning process in piglets by anterior/posterior pattern specification as well as the cancer, PI3K-Akt, MAPK, GnRH, and neurotrophin signaling pathways. | Jang, Hyun Jun; Lee, Sang In | Ctr Ind Agr & Livestock Microorganisms, Jeongeup 56212, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, South Korea | 56221023000; 57203597336 | silee78@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 4 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 0.84 | 2025-07-30 | 8 | 8 | miRNA; Small RNA sequencing; Weaning pigs | INTESTINAL BARRIER FUNCTION; GENE-EXPRESSION; IMPAIRS | MiRNA; Small RNA sequencing; Weaning pigs | English | 2021 | 2021 | 10.5187/jast.2021.e69 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Relationship between oxytocin and serotonin and the fearfulness, dominance, and trainability of horses | Oxytocin (OXT) and serotonin (5-HT) are essential neurotransmitters associated with the behavior of animals. Recently, we found that the plasma concentration of OXT is positively correlated with horse docility and friendliness toward humans. However, the relationships between the neurotransmitters and other temperaments such as fearfulness, dominance, and trainability are unknown. This study aimed to identify whether the plasma concentration of OXT or 5-HT is correlated with fearfulness, dominance, and trainability of horses. Blood samples of 34 horses were collected at the Horse Industry Complex Center of Jeonju Kijeon College. The concentration of OXT and 5-HT was measured in the plasma samples using enzyme-linked immunosorbent assays. The fearfulness, dominance, and trainability of horses were scored by three professors who were very familiar with the horses. One-way analysis of variance with the least significant difference post-hoc analysis was used to compare the scores for fearfulness and dominance among groups. The trainability of horses was compared using the student t-test. The 5-HT was negatively correlated with dominance, but it had no relation with fearfulness. The OXT appeared to be negatively correlated with fearfulness and dominance in horses. Furthermore, OXT was positively correlated with the trainability of horses. Additionally, 5-HT appeared to enhance trainability. In conclusion, the concentration of OXT or 5-HT in horse blood plasma can be used as a biomarker to monitor the fearfulness, dominance, or trainability of horses. | Kim, Junyoung; Park, Youngjae; Kim, Eun Joong; Jung, Heejun; Yoon, Minjung | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Jeonju Kijeon Coll, Dept Equine Ind & Sports Therapeut Riding, Jeonju 54989, South Korea; Kyungpook Natl Univ, Dept Anat, Sch Med, Daegu 41944, South Korea | Kim, Eun Joong/HGF-1639-2022 | 57218494918; 57223212536; 57213620881; 56374279800; 22137296500 | mjyoon@knu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 2 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 1.2 | 2025-07-30 | 11 | 12 | Horses; Oxytocin; Serotonin; Fearfulness; Dominance; Trainability | PERFORMANCE; BEHAVIOR; RELEASE | Dominance; Fearfulness; Horses; Oxytocin; Serotonin; Trainability | English | 2021 | 2021 | 10.5187/jast.2021.e29 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The prevalence of causative agents of calf diarrhea in Korean native calves | Infectious calf diarrhea is one of the most significant diseases of neonatal calves. This study is conducted to identify the prevalence of pathogens in calf diarrhea for 2 years. A total of 544 feces samples from Korean native beef calves were obtained to investigate selected seven pathogens causing calf diarrhea: bovine rotavirus, bovine coronavirus, Cryptosporidium parvum, bovine viral diarrhea virus, Eimeria species, Escherichia coli K99, and Salmonella species. The presence of diarrhea, the number and species of detected pathogens, and the calves' ages were analyzed using various statistical methods depending on the case. Of the 544 calves, 340 calves (62.5%) had normal feces and 204 calves (37.5%) had diarrhea. The presence of pathogens was significantly associated with diarrhea (p < 0.01) and fecal scores and the number of detected pathogens showed a significant linear trend (p < 0.001). Of the 7 target pathogens, 6 were detected in samples, but only C. parvum (p = 0.001) and bovine rotavirus (p < 0.001) were found at significantly higher rates in diarrheic calves than in non-diarrheic calves. Only Eimeria spp. showed a significant linear trend between the detection rate of the pathogen and the age groups (p < 0.05). | Chae, Jeong-Byoung; Kim, Hyeon-Cheol; Kang, Jun-Gu; Choi, Kyoung-Seong; Chae, Joon-Seok; Yu, Do-Hyeon; Park, Bae-Keun; Oh, Yeon-su; Choi, Hak-Jong; Park, Jinho | Seoul Natl Univ, Res Inst Vet Sci, BK21 PLUS Program Creat Vet Sci Res, Lab Vet Internal Med, Seoul 08826, South Korea; Seoul Natl Univ, Coll Vet Med, Seoul 08826, South Korea; Kangwon Natl Univ, Coll Vet Med, Chunchon 24341, South Korea; Kangwon Natl Univ, Inst Vet Sci, Chunchon 24341, South Korea; Jeonbuk Natl Univ, Korea Zoonosis Res Inst, Iksan 54531, South Korea; Kyungpook Natl Univ, Coll Ecol & Environm Sci, Sangju 37224, South Korea; Gyeongsang Natl Univ, Inst Anim Med, Coll Vet Med, Jinju 52828, South Korea; Chungnam Natl Univ, Coll Vet Med, Daejeon 34134, South Korea; World Inst Kimchi, Div Res & Dev, Microbiol & Funct Res Grp, Gwangju 61755, South Korea; Jeonbuk Natl Univ, Coll Vet Med, Dept Vet Internal Med, Iksan 54596, South Korea | ; Chae, Jeong/AAP-6038-2021; Choi, Hak-Jong/I-5640-2019 | 57037983200; 35345454300; 57219662095; 7403949556; 7102478039; 14623495400; 37043844700; 57188664571; 8415034400; 8730126700 | hjchoi@wikim.re.kr;jpark@jbnu.ac.kr; | JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY | J ANIM SCI TECHNOL | 2672-0191 | 2055-0391 | 63 | 4 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE;VETERINARY SCIENCES | 2021 | 1.801 | 39.7 | 1.08 | 2025-07-30 | 10 | 11 | Calf diarrhea; Korean native beef calves; Enteric pathogens; Prevalence | REAL-TIME PCR; ANTIMICROBIAL RESISTANCE; DAIRY CALVES; RISK-FACTORS; SPP.; CRYPTOSPORIDIUM; ENTEROPATHOGENS; ETIOLOGY; EIMERIA; SAMPLES | Calf diarrhea; Enteric pathogens; Korean native beef calves; Prevalence | English | 2021 | 2021 | 10.5187/jast.2021.e63 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | A Simple Method for Continuous Synthesis of Bicelles in Microfluidic Systems | Bicelle has great potential for drug delivery systems due to its small size and biocompatibility. The conventional method of bicelle preparation contains a long process and harsh conditions, which limit its feasibility and damage the biological substances. For these reasons, a continuous manufacturing method in mild conditions has been demanded. Here, we propose a novel method for DMPC/DHPC bicelle synthesis based on a microfluidic device without heating and freezing processes. Bicelles were successfully prepared using this continuous method, which was identified by the physicochemical properties and morphologies of the synthesized assemblies. Experimental and analytical studies confirm that there is critical lipid concentration and critical mixing time for bicelle synthesis in this microfluidic system. Furthermore, a linear relation between the actual composition of bicelle and initial lipid ratio is deduced, and this enables the size of bicelles to be controlled. | Choi, Sunghak; Kang, Bongsu; Taguchi, Shogo; Umakoshi, Hiroshi; Kim, Keesung; Kwak, Moon Kyu; Jung, Ho-Sup | Seoul Natl Univ, Ctr Food & Bioconvergence, Dept Food Sci & Biotechnol, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Univ Hyogo, Dept Chem Engn & Mat Sci, Grad Sch Engn, Himeji, Hyogo 6712280, Japan; Osaka Univ, Div Chem Engn, Grad Sch Engn Sci, Toyonaka, Osaka 5608531, Japan; Seoul Natl Univ, Res Inst Adv Mat, Coll Engn, Seoul 08826, South Korea | ; Kwak, Moon/AGQ-6058-2022; UMAKOSHI, HIROSHI/O-4583-2016; Jung, Hosup/AAB-5708-2020; KIM, SUNG MIN/U-5269-2017 | 57264013200; 55330925300; 57059904200; 6701925853; 35484342500; 57203947984; 36985354800 | keesung@snu.ac.kr;mkkwak@knu.ac.kr;jhs@snu.ac.kr; | LANGMUIR | LANGMUIR | 0743-7463 | 37 | 42 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | 4.331 | 39.9 | 0.64 | 2025-07-30 | 9 | 9 | MEMBRANE; LAURDAN; SIZE | Dimyristoylphosphatidylcholine; Lipid Bilayers; Magnetic Resonance Spectroscopy; Micelles; Microfluidics; Biocompatibility; Controlled drug delivery; Microfluidics; Physicochemical properties; dimyristoylphosphatidylcholine; Bicelles; Biological substance; Condition; Continuous manufacturing; Continuous synthesis; Conventional methods; Drug-delivery systems; Manufacturing methods; Microfluidics systems; SIMPLE method; lipid bilayer; micelle; microfluidics; nuclear magnetic resonance spectroscopy; Fluidic devices | English | 2021 | 2021-10-26 | 10.1021/acs.langmuir.1c02024 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Ammonium-mediated reduction in salicylic acid content and recovery of plant growth in Arabidopsis siz1 mutants is modulated by NDR1 and NPR1 | The siz1 mutants exhibit high SA accumulation and consequently severe dwarfism. Although siz1 mutants exhibit growth recovery upon exogenous ammonium supply, the underlying mechanism remains unknown. Here, we investigated the effect of ammonium on SA level and plant growth in SA-accumulating mutants. The growth of siz1-2 and siz1-3 mutants was recovered to wild-type (WT) levels upon exogenous ammonium supply, but that of siz1-3 ndr1 (non-race-specific disease resistance 1) and siz1-3 npr1 (non-expressor of pathogenesis related gene 1) double mutants was unaffected. The SA level was decreased by exogenous ammonium application in siz1-3 ndr1, siz1-3 npr1, and siz1-3 mutants. The level of nitrate reductase (NR) was almost the same in all genotypes (WT, siz1-3, ndr1, npr1, siz1-3 ndr1, and siz1-3 npr1), regardless of the ammonium treatment, suggesting that exogenous ammonium supply to ndr1 siz1-3 and npr1 siz1-3 double mutants does not have any effect on their growth and NR levels, but decreases the SA level. Taken together, these results indicate that ammonium acts as a signaling molecule to regulate the SA amount, and NDR1 and NPR1 play a positive role in the ammonium-mediated growth recovery of siz1 mutants. | Kim, Ju Yong; Song, Jong Tae; Seo, Hak Soo | Seoul Natl Univ, Res Inst Agr & Life Sci, Dept Agr Forestry & Bioresources, Seoul, South Korea; Seoul Natl Univ, Plant Genom & Breeding Inst, Seoul, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu, South Korea; Seoul Natl Univ, BioMAX Inst, Seoul, South Korea | KIM, JOO YONG/JBJ-6285-2023 | 58529814100; 57797134000; 26642769200 | seohs@snu.ac.kr; | PLANT SIGNALING & BEHAVIOR | PLANT SIGNAL BEHAV | 1559-2316 | 1559-2324 | 16 | 9 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;PLANT SCIENCES | 2021 | 2.734 | 40.0 | 0.55 | 2025-07-30 | 7 | 7 | Ammonium; AtSIZ1; nitrate reductase; salicylic acid; ndr1; npr1 | SYSTEMIC ACQUIRED-RESISTANCE; SUMO LIGASE ATSIZ1; PSEUDOMONAS-SYRINGAE; NH4+; NUTRITION; REVEALS; PROTEIN; STRESS; COP1 | Ammonium; AtSIZ1; ndr1; nitrate reductase; npr1; salicylic acid | Ammonium Compounds; Arabidopsis; Gene Expression Regulation, Plant; Genes, Plant; Genetic Variation; Genotype; Mutation; Salicylic Acid; ammonium derivative; salicylic acid; Arabidopsis; comparative study; gene expression regulation; genetic variation; genetics; genotype; growth, development and aging; metabolism; mutation; plant gene | English | 2021 | 2021-09-02 | 10.1080/15592324.2021.1928819 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
