| ○ | ○ | Article | A Search for Exoplanets around Northern Circumpolar Stars. VII. Detection of Planetary Companion Orbiting the Largest Host Star HD 18438 | We have been conducting a exoplanet search survey using Bohyunsan Observatory Echelle Spectrograph (BOES) for the last 18 years. We present the detection of exoplanet candidate in orbit around HD 18438 from high-precision radial velocity (RV) mesurements. The target was already reported in 2018 (Bang et al. 2018). They conclude that the RV variations with a period of 719 days are likely to be caused by the pulsations because the Lomb-Scargle periodogram of HIPPARCOS photometric and H alpha EW variations for HD 18438 show peaks with periods close to that of RV variations and there were no correlations between bisectors and RV measurements. However, the data were not sufficient to reach a firm conclusion. We obtained more RV data for four years. The longer time baseline yields a more accurate determination with a revised period of 803 +/- 5 days and the planetary origin of RV variations with a minimum planetary companion mass of 21 +/- 1 MJup. Our current estimate of the stellar parameters for HD 18438 makes it currently the largest star with a planetary companion. | Lee, Byeong-Cheol; Koo, Jae-Rim; Jeong, Gwanghui; Park, Myeong-Gu; Han, Inwoo; Choi, Yeon-Ho | Korea Astron & Space Sci Inst, 776,Daedeok Daero, Daejeon, South Korea; Univ Sci & Technol, Astron & Space Sci Major, 217,Gajeong Ro, Daejeon, South Korea; Kongju Natl Univ, 56,Gongjudaehak Ro, Gongju Si, Chungcheongnam, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, 80,Daehak Ro, Daegu, South Korea | 8878262900; 15127066700; 56152551500; 7404490321; 7201559866; 57247914500 | bclee@kasi.re.kr; | JOURNAL OF THE KOREAN ASTRONOMICAL SOCIETY | J KOREAN ASTRON SOC | 1225-4614 | 56 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 1.1 | 69.6 | 0.12 | 2025-06-25 | 1 | 1 | star; individual; HD 18438; techniques; radial velocities | GIANT STARS; STELLAR; II. | star: individual: HD 18438; techniques: radial velocities | English | 2023 | 2023-03 | 10.5303/jkas.2023.56.1.35 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Search for Exoplanets around Northern Circumpolar Stars. VIII. Filtering Out a Planet Cycle from the Multi-Period Radial Velocity Variations in M Giant HD 36384 | This paper is written as a follow-up observations to reinterpret the radial velocity (RV) of HD 36384, where the existence of planetary systems is known to be ambiguous. In giants, it is, in general, difficult to distinguish the signals of planetary companions from those of stellar activities. Thus, known exoplanetary giant hosts are relatively rare. We, for many years, have obtained RV data in evolved stars using the high-resolution, fiber-fed Bohyunsan Observatory Echelle Spectrograph (BOES) at the Bohyunsan Optical Astronomy Observatory (BOAO). Here, we report the results of RV variations in the M giant HD 36384. We have found two significant periods of 586 d and 490 d. Considering the orbital stability, it is impossible to have two planets at so close orbits. To determine the nature of the RV variability variations, we analyze the HIPPARCOS photometric data, some indicators of stellar activities, and line profiles. A significant period of 580 d was revealed in the HIPPARCOS photometry. H-alpha EW variations also show a meaningful period of 582 d. Thus, the period of 586 d may be closely related to the rotational modulations and/or stellar pulsations. On the other hand, the other significant period of 490 d is interpreted as the result of the orbiting companion. Our orbital fit suggests that the companion was a planetary mass of 6.6M(J) and is located at 1.3 AU from the host. | Lee, Byeong-Cheol; Jeong, Gwanghui; Koo, Jae-Rim; Lim, Beomdu; Park, Myeong-Gu; Bang, Tae-Yang; Choi, Yeon-Ho; Oh, Hyeong-Ill; Han, Inwoo | Korea Astron & Space Sci Inst, Daejeon 34055, South Korea; Korea Univ Sci & Technol, Daejeon 34113, South Korea; Antbridge Inc, Space Sci Res Ctr, Daejeon 34120, South Korea; Kongju Natl Univ, Dept Earth Sci Educ, Kong Ju 314701, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 702701, South Korea | 8878262900; 56152551500; 15127066700; 36499772800; 7404490321; 57201317966; 57247914500; 59098226900; 7201559866 | bclee@kasi.re.kr; | JOURNAL OF THE KOREAN ASTRONOMICAL SOCIETY | J KOREAN ASTRON SOC | 1225-4614 | 56 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 1.1 | 69.6 | 0.12 | 2025-06-25 | 0 | 1 | stars: individual: HD 36384; techniques: radial velocities; stars: planetary systems | HARPS SEARCH; VARIABILITY; ALDEBARAN; EARTH | HD 36384 — techniques; individual; planetary systems; radial velocities — stars; stars | English | 2023 | 2023-04 | 10.5303/jkas.2023.56.2.195 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Real-world toxicity and effectiveness of ixazomib, lenalidomide, and dexamethasone in Korean patients with relapsed and/or refractory multiple myeloma | Background/aim Ixazomib, lenalidomide, and dexamethasone (IRd) have proven efficacy and an excellent safety profile in relapsed and/or refractory multiple myeloma (RRMM). However, there are limited reports on the real-world safety and effectiveness of IRd regimens in Asian patients with RRMM. Patients and methods This was a retrospective study of 60 patients with RRMM who were treated with IRd. Results The median patient age was 68 years. Forty percent of patients did not meet the eligibility criteria for the TOURMALINE-MM1 trial. Patients received a median of one prior line of therapy. Non-hematologic adverse events (AEs) were more common than hematologic AEs. The most common AE was skin rash, followed by gastrointestinal toxicities. Most grade 3 or higher AEs were observed in less than 5% of the patients, except for skin rashes and infections. IRd therapy did not aggravate peripheral neuropathy (PN) in 20 of the 24 patients with pre-existing peripheral neuropathy. The overall response rate was 85%. After a median follow-up of 26.3 months, the median progression-free survival was 25.9 months and overall survival was not reached. Conclusion Ixazomib and Rd combination therapy had a comparable toxicity profile and effectiveness in real-world RRMM patients. | Lee, Ji Hyun; Kim, Sung-Hyun; Kim, Hye Ryeon; Min, Chang-Ki; Lee, Je-Jung; Shin, Ho-Jin; Jo, Jae-Cheol; Lee, Ji Yun; Moon, Joon Ho; Kim, Kihyun | Dong A Univ, Dept Internal Med, Coll Med, Busan, South Korea; Catholic Univ Korea, Seoul St Marys Hematol Hosp, Dept Hematol, Coll Med, Seoul, South Korea; Chonnam Natl Univ, Med Sch, Dept Hematol Oncol, Hwasun Hosp, Hwasun, South Korea; Pusan Natl Univ Hosp, Med Res Inst, Sch Med, Div Hematol Oncol, Busan, South Korea; Univ Ulsan, Ulsan Univ Hosp, Dept Hematol & Oncol, Coll Med, Ulsan, South Korea; Seoul Natl Univ, Dept Internal Med, Bundang Hosp, Seongnam, South Korea; Kyungpook Natl Univ, Sch Med, Div Hematol Oncol, Dept Internal Med, 130 Dongduk Ro, Daegu 41944, South Korea; Sungkyunkwan Univ, Div Hematol Oncol, Dept Med, Sch Med,Samsung Med Ctr, 81 Irwon Ro, Seoul 06351, South Korea | Lee, Jong-Seok/J-5603-2012; Kim, Kihyun/D-5175-2013; Kim, Hye Ryeon/KIG-7417-2024; Lee, Jung-Hye/F-6974-2013 | 56813113800; 56547959500; 57345002100; 57224962914; 7601478211; 16239868400; 35818309200; 56510286700; 56568642700; 57199440300 | jhmoon@knu.ac.kr;kihyunkimk@gmail.com; | INTERNATIONAL JOURNAL OF HEMATOLOGY | INT J HEMATOL | 0925-5710 | 1865-3774 | 117 | 2 | SCIE | HEMATOLOGY | 2023 | 1.7 | 69.6 | 0.88 | 2025-06-25 | 6 | 6 | Ixazomib; Lenalidomide; Real-world; Asia; Relapsed; Refractory; Multiple myeloma | ORAL IXAZOMIB; SURVIVAL; CARFILZOMIB; THERAPY | Asia; Ixazomib; Lenalidomide; Multiple myeloma; Real-world; Refractory; Relapsed | Aged; Antineoplastic Combined Chemotherapy Protocols; Boron Compounds; Dexamethasone; Exanthema; Humans; Lenalidomide; Multiple Myeloma; Peripheral Nervous System Diseases; Republic of Korea; Retrospective Studies; bortezomib; dexamethasone; ixazomib; ixazomib citrate; lenalidomide; thalidomide; antineoplastic agent; boron derivative; dexamethasone; ixazomib; lenalidomide; abdominal discomfort; acute kidney failure; adult; aged; anemia; Article; backache; constipation; cytogenetics; diarrhea; drug efficacy; drug withdrawal; duodenitis; dyspepsia; dyspnea; fatigue; female; fever; follow up; gastrointestinal toxicity; headache; heart arrhythmia; herpes zoster; human; infection; insomnia; interstitial lung disease; kidney failure; Korean (people); liver failure; major clinical study; male; middle aged; multiple myeloma; nausea; neutropenia; overall response rate; overall survival; peripheral edema; peripheral neuropathy; pneumonia; progression free survival; rash; retrospective study; survival rate; thrombocytopenia; vomiting; epidemiology; multiple myeloma; peripheral neuropathy; rash; South Korea | English | 2023 | 2023-02 | 10.1007/s12185-022-03479-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Solar North-South Asymmetry and Hilbert Transform Analysis | Here, we investigated the observed sunspot areas with respect to latitudes using the Hilbert transform technique. Conventional study of the cyclic patterns of sunspots is based on the Lomb-Scargle periodogram, which only obtains the amplitude information. In comparison, our approach characterizes the amplitude as well as the phase of solar activity. We demonstrated the solar Nor th-South asymmetry in the instantaneous amplitude by analyzing daily sunspot data set spanning from the solar cycles 11 to 24. Our findings confirm that the northern hemisphere is dominant in the solar cycles 14, 15, 16, 18, and 20. Unlike the amplitude, the Nor th-South asymmetry in the period of solar activity could not be established. We have also found that the standard deviation as a measure of fluctuation in the phase derivative is minimum in the latitude band 10 degrees < l < 20 degrees, and the fluctuations obtained for latitudes above 30 degrees are considerable. | Chang, Heon-Young | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea | 7407524806 | hyc@knu.ac.kr; | JOURNAL OF THE KOREAN ASTRONOMICAL SOCIETY | J KOREAN ASTRON SOC | 1225-4614 | 56 | 1 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 1.1 | 69.6 | 0 | 2025-06-25 | 0 | 0 | Sun: sunspot; Sun: activity; methods: data analysis | N-S ASYMMETRY; MAGNETIC-FIELD REVERSAL; LONG-TERM VARIATIONS; NUMBERS R-N; LATITUDINAL DISTRIBUTION; DIFFERENTIAL ROTATION; PERIODIC BEHAVIOR; FLUX TRANSPORT; SUNSPOT CYCLE; DYNAMO | methods: data analysis; Sun: activity; Sun: sunspot | English | 2023 | 2023-04 | 10.5303/jkas.2023.56.1.125 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | An annotated checklist of grasshoppers (Orthoptera, Acridoidea) from Mongolia | Background Grasshoppers (Acridoidea, Orthoptera) are the dominant herbivores in grassland ecosystems worldwide. They can increase rangeland productivity by stimulating plant growth and accelerating nutrient cycling. This article presents a comprehensive checklist of grasshoppers in Mongolia. Until then, the available information was very scattered, based on old studies of Mongolian grasshoppers, recorded in a few international catalogues and databases, individual records and research work on agroecosystem communities. However, the available information on the composition of the Orthopteran fauna in Mongolia was sometimes unclear or non-existent and these dubious data were excluded from the present study. In addition, the grasshopper distribution analysis used the standardised personal collection of D. Altanchimeg. We also present a list of grasshoppers, as well as their distribution and abundance, in countries adjacent to Mongolia, such as Russia, China and South Korea. The surveys covered six types of natural zones: high mountain, taiga, forest-steppe, steppe, desert steppe and desert; desert steppe and steppe zones are the most widely distributed. We hope to have contributed significantly to the study of the distribution of grasshopper species in all these natural zones. New information In this study, a total of three families of Acridoidea belonging to eight subfamilies, 17 tribes, 52 genera and 128 species are reported for the various natural zones. The recorded species belong to eight subfamilies: Gomphocerinae are the most numerous with 56 species recorded, followed by Oedipodinae (51 species), Thrinchinae (nine species), Melanoplinae (six species), Calliptaminae (three species), Dericorythinae, Acridinae, Egnatiinae (one species each). | Gankhuyag, Enkhtsetseg; Dorjsuren, Altanchimeg; Choi, Eun Hwa; Hwang, Ui Wook | Kyungpook Natl Univ, Teachers Coll, Dept Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Phylogen & Evolut, Daegu 41566, South Korea; Mongolian Acad Sci, Inst Biol, Ulaanbaatar 133330, Mongolia; Inner Mongolia Univ, Coll Life Sci, Hohhot 010031, Peoples R China; Kyungpook Natl Univ, Inst Phylogen & Evolut, Teachers Coll, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Korean Herb Bio Convergence Promot, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Ind Technol Adv, Daegu 41566, South Korea; Phylomics Inc, Daegu 41910, South Korea | Choi, Eun Hwa/HTN-1610-2023 | 58182170600; 6507933989; 57203556599; 35074015800 | uwhwang@knu.ac.kr; | BIODIVERSITY DATA JOURNAL | BIODIVERS DATA J | 1314-2836 | 1314-2828 | 11 | SCIE | BIODIVERSITY CONSERVATION | 2023 | 1 | 70.0 | 1 | 2025-06-25 | 3 | 4 | distribution; fauna; natural zone; Pamphagidae; Acrididae; Dericorythidae; Mongolia | ACRIDIDAE; REGION | Acrididae; Dericorythidae; distribution; fauna; Mongolia; natural zone; Pamphagidae | China; Mongolia; Russian Federation; South Korea; agricultural ecosystem; database; desert; fauna; grasshopper; grassland; rangeland; research work; species inventory; steppe | English | 2023 | 2023-03-13 | 10.3897/bdj.11.e96705 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article; Data Paper | Insect fauna including unrecorded species in Ulleungdo, South Korea | Ulleungdo harbours a unique ecosystem owing to its isolation from the mainland alongside its maritime climate. The island, formed via volcanic activity, is the largest island in the East Sea of Korea and retains a primeval forest. The ecosystems are being destroyed owing to increasing human activity on the island. Therefore, through the investigation of the insect fauna of Ulleungdo, we tried to provide information that can be the basis for understanding the island ecology of Ulleungdo. This survey was conducted four times between April and October in 2020 at Seonginbong. | Won, Min Hyeok; Choi, Jae Won; Bang, WooJun; Lee, DongYeol; Moon, Min Ki; Kim, Young-Kun; Kim, Donguk; Kim, Dooyoung; Suh, Sang Jae; Choi, Kwang Shik | Kyungpook Natl Univ, Sch Life Sci, FOUR KNU Creat Biores Grp BK21, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Daegu, South Korea; Seoul Natl Univ, Sch Biol Sci, Seoul, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu, South Korea; Kyungpook Natl Univ, Inst Plant Med, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Phylogen & Evolut, Daegu, South Korea | ; Choi, Jae Won/HNP-9496-2023; Kim, Donguk/AIE-1445-2022; Won, Min Hyeok/GRO-0206-2022 | 57226384585; 57377209500; 57225182172; 57377518800; 57917337300; 57222033782; 57218602310; 57759300300; 15754843200; 36602283400 | ksc@knu.ac.kr; | BIODIVERSITY DATA JOURNAL | BIODIVERS DATA J | 1314-2836 | 1314-2828 | 11 | SCIE | BIODIVERSITY CONSERVATION | 2023 | 1 | 70.0 | 0.75 | 2025-06-25 | 3 | 3 | Insecta; island; diversity; database; new records; Palearctic | ISLANDS | database; diversity; Insecta; island; new records; Palearctic | South Korea; forest ecosystem; geographical distribution; human activity; insect; island; new record; Palearctic Region; species diversity | English | 2023 | 2023-05-11 | 10.3897/bdj.11.e100783 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Molecular investigation on diversity of the land snail genus Aegista (Gastropoda, Camaenidae) in South Korea | Aegista Albers, 1850 is a large genus of the land snail family Camaenidae Pilsbry, 1895 and distributed in south, southeast and east Asian countries (from India and Nepal to Korea and Japan). Fourteen species and subspecies of Aegista are known from South Korea. They were described, based only on shell morphology during 1887-1943 and our knowledge on diversity of Korean Aegista has seldom been updated since then. In this study, we provide the report on the first molecular investigation of diversity of Aegista in South Korea, which unmasked some of overlooked diversity of this group. | Kimura, Kazuki; Chiba, Satoshi; Pak, Jae-Hong | Tohoku Univ, Ctr Northeast Asian Studies, Sendai, Japan; Kyungpook Natl Univ, Dept Biol, Taegu, South Korea | ; Kimura, Kazuki/AAF-4137-2020 | 55464858400; 55697248000; 7102232932 | k.kimura.000@gmail.com; | BIODIVERSITY DATA JOURNAL | BIODIVERS DATA J | 1314-2836 | 1314-2828 | 11 | SCIE | BIODIVERSITY CONSERVATION | 2023 | 1 | 70.0 | 0.25 | 2025-06-25 | 1 | 1 | Aegista; cryptic species; land snails; molecular phylogeny; the Korean Peninsula | PALEOENVIRONMENTAL CHANGES; PULMONATA BRADYBAENIDAE; YELLOW SEA; MORPHOLOGY; ALIGNMENT; LANDOURIA | Aegista; cryptic species; land snails; molecular phylogeny; the Korean Peninsula | India; Japan; Korea; Nepal; South Korea; knowledge; molecular analysis; molecular ecology; phylogeny; snail; species diversity; subspecies | English | 2023 | 2023-01-31 | 10.3897/bdj.11.e96800 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A high bandwidth, high voltage amplifier for driving fast piezoelectric actuator-based nanopositioners used in atomic force microscopes | Some of the challenges of adapting high-voltage amplifier (HVA) designs and solutions for driving highly capacitive loads such as piezoelectric actuators (PEAs) fast include cost, implementation complexity, management of thermal load, and difficult customization. In this work, we develop an easy to implement HVA with 525 kHz small signal bandwidth, 6 A(pp), and 110 V-pp HVA using a low-cost high voltage operational amplifier (HV-OPA) and a self-biasing power amplifier (PA). At 100 kHz, the phase lag is about -24 degrees and the HVA can be configured for use with or without the PA stage to prioritize input tracking and output noise reduction or output stability improvement. When used to drive our custom high-speed atomic force microscope (HS-AFM) Z-scanner during imaging, compared to a conventional commercial HVA, our custom HVA is able to track topographical features at faster scan speeds. | Otieno, Luke Oduor; Nguyen, Thi Thu; Juma, Oyoo Michael; Nguyen, Thi Ngoc; Lee, Yong Joong; Park, Jae Sung; Lee, Ho; Alunda, Bernard Ouma | Kyungpook Natl Univ, Sch Mech Engn, 80,Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Nanophoton Applicat, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Convergence, Dept Robot & Smart Syst Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Laser Applicat Ctr, 70 Dongnae Ro, Daegu 41061, South Korea; Taita Taveta Univ, Sch Mines & Engn, POB 635, Voi 80300, Kenya | ; Otieno, Luke/KHW-8698-2024 | 57205578290; 58811314600; 58553964600; 57216184573; 57183248500; 57221145710; 26660670700; 55354745500 | yjlee76@knu.ac.kr;holee@knu.ac.kr; | JOURNAL OF THE KOREAN PHYSICAL SOCIETY | J KOREAN PHYS SOC | 0374-4884 | 1976-8524 | 83 | 10 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2023 | 0.8 | 70.1 | 0.12 | 2025-06-25 | 1 | 1 | High-speed atomic force microscope; High voltage amplifier; Piezo drivers; Piezoelectric actuators; High-speed atomic force microscope scanners | High voltage amplifier; High-speed atomic force microscope; High-speed atomic force microscope scanners; Piezo drivers; Piezoelectric actuators | English | 2023 | 2023-11 | 10.1007/s40042-023-00911-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of a monoenergetic neutron field utilizing an accelerator deuteron beam | A monoenergetic neutron field is an attractive environment for neutron metrology and the development of novel neutron detectors. Deuterium-deuterium and deuterium-tritium (DT) reactions with an accelerated deuteron beam produce 2.5 and 14.8 MeV monoenergetic neutrons, respectively. The Korea Research Institute of Standards and Science (KRISS) is developing a monoenergetic neutron field facility with an accelerator that generates a deuteron beam to establish monoenergetic neutron measurement standards. An electrostatic accelerator with a maximum high voltage of 400 kV and beam current from 0.5 to 500 mu A from High Voltage Engineering Europa BV was installed. For a tritiated titanium or deuterated titanium target deposited at 250 mu g/cm(2) on a 38 mm copper plate, a target chamber is developed by KRISS. The total neutron yield is limited to 5 x 10(8) n/s, which is the maximum allowed emission rate resulting from the shielding capacitance of a laboratory wall shield. The corresponding deuteron beam current of the DT reaction with the maximum emission rate is approximately 15 mu A. Furthermore, various additional studies such as beam current monitoring, target temperature monitoring, air cooling for the target, and beam profile measurement have been performed for the stable generation of the monoenergetic neutron field. | Park, HyeoungWoo; Kang, Sinchul; Kim, Jungho; Park, Hyeonseo; Kim, Joong Hyun; Yoon, Young Soo | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Korea Res Inst Stand & Sci, Daejeon 34113, South Korea | Yoon, Young Soo/O-8580-2014; Kang, Sinchul/GQY-6652-2022 | 58950744700; 57191418531; 56784564000; 57216599536; 57202767439; 35243798200 | ysy@kriss.re.kr; | JOURNAL OF THE KOREAN PHYSICAL SOCIETY | J KOREAN PHYS SOC | 0374-4884 | 1976-8524 | 83 | 8 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2023 | 0.8 | 70.1 | 0.37 | 2025-06-25 | 2 | 3 | Monoenergetic neutron field; Accelerator deuteron beam | CROSS-SECTION | Accelerator deuteron beam; Monoenergetic neutron field | English | 2023 | 2023-10 | 10.1007/s40042-023-00847-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Luminescence properties of Dy³⁺ doped germanosilicate glass scintillator using proton beam | We have investigated novel GeO2-SiO2 glass scintillators doped with Dy3+ ions. The conventional melt-quenching technique prepares germanosilicate glass scintillators. Optical and physical properties of the samples are measured, such as X-ray dif-fraction and glass transition temperature. We used different radiation sources, including LED, X-ray, and proton beams, to investigate the luminescence characteristics of the germanosilicate glass scintillator. We measured the transmittance spectra to comprehend the absorption state. Further research into the transition states of the Dy3+ doped glass scintillator involves the measurement of the X-ray, LED, and proton-induced emission spectra. | Cho, J. Y.; Lee, D. H.; Jeong, D.

The LVRAD instrument consists of the lunar radiation dosimeter and spectrometer, and the neutron spectrometer. The (LiI)-Li-6:Ag scintillators are used for the thermal and epithermal neutron spectrometer from the LVRAD instrument. (LiI)-Li-6:Ag measures neutron energy from Li-6(n, ?)H-3 reaction and it can separate neutron signals from gamma rays using pulse shape discrimination. Because of the radiation environment on a lunar surface, such as cosmic rays, and albedo neutrons, the radiation damage effects of (LiI)-Li-6:Ag should be investigated for the LVRAD experiment. 45 MeV proton beam in the Korea Institute of Radiological and Medical Sciences is used for the radiation hardness test. The pulse height spectra from 511 keV gamma rays decrease by 13.2%, and the figure of merit values of pulse shape discrimination decrease by 8% when the absorbed dose is 3508 rad. The emission peak intensity at 495 nm decreases by similar to 30% when the absorbed dose is 1300 x 10(3) rad. The results show that (LiI)-Li-6:Ag has high radiation hardness and can be used in high-radiation environments. | Kang, Sinchul; Yoon, Young Soo; Kim, Hongjoo; Lee, Doohyeok; Luan, Nguyen Thanh; Park, Hyeoungwoo; Quang, Nguyen Duy; Vuong, Phan Quoc; Choi, Young-Jun; Nam, Uk-Won; Park, Won-Kee; Sohn, Jongdae; Ye, Sung-Joon; Youn, Sukwon; Kim, Sunghwan | Korea Res Inst Stand & Sci, Daejeon 34113, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Korea Astron & Space Sci Inst, Space Sci Div, Daejeon 34055, South Korea; Seoul Natl Univ, Grad Sch Convergence Sci & Technol, Dept Appl Bioengn, Seoul 08826, South Korea; Cheongju Univ, Dept Radiol Sci, Cheongju 28503, South Korea | ; Thanh Duong, Nguyen/AGY-4248-2022; Kim, Hong Joo/AAE-1178-2022; Yoon, Young Soo/O-8580-2014 | 57191418531; 35243798200; 59051568100; 59639095100; 57210576969; 58950744700; 57223004024; 57207618553; 55685945500; 6602840978; 35285730800; 55193404200; 7202088315; 57210900037; 36165569900 | hongjoo@knu.ac.kr; | JOURNAL OF THE KOREAN PHYSICAL SOCIETY | J KOREAN PHYS SOC | 0374-4884 | 1976-8524 | 83 | 2 | SCIE | PHYSICS, MULTIDISCIPLINARY | 2023 | 0.8 | 70.1 | 0.12 | 2025-06-25 | 1 | 1 | LVRAD; (LiI)-Li-6:Ag; Radiation | LITHIUM IODIDE; ACTIVATION | <sup>6</sup>LiI:Ag; LVRAD; Radiation | English | 2023 | 2023-07 | 10.1007/s40042-023-00846-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Jujuboside B Inhibited High Mobility Group Box Protein 1-Mediated Severe Inflammatory Responses in Human Endothelial Cells and Mice | High mobility group box protein 1 (HMGB1) is a biomolecule that acts as an alerting signal of late sepsis by accelerating the production of proinflammatory cytokines, and eventually leads to various inflammation-related symptoms. When released into plasma at high concentration, it disrupts precise diagnosis and prognosis and worsens the survival of patients with systemic inflammatory conditions. Jujuboside B (JB) is a natural compound pressed from the seed of Zizyphi Spinosi Semen, which is known for its medical efficacies in treating various conditions such as hyperlipidemia, hypoxia, and platelet aggregation. Nevertheless, the medicinal activity of JB on HMGB1-involved inflammatory response in vascular cells in the human body is still ambiguous. Therefore, we hypothesized that JB could regulate the lipopolysaccharide (LPS)-induced dynamics of HMGB1 and its mediated cascade in inflammatory responses in human umbilical vein endothelial cells (HUVECs). In this experiment, JB and HMGB1 were administered in that order. In vitro and in vivo permeability, and cell viability, adhesion, and excavation of leukocytes, development of cell adhesion molecules, and lastly production of proinflammatory substances were investigated on human endothelial cells and mouse disease models to investigate the efficacy of JB in inflammatory condition. JB substantially blocked the translocation of HMGB1 from HUVECs and controlled HMGB1-induced adhesion and extravasation of the neutrophils through LPS-treated HUVECs. Moreover, JB decreased the formation of HMGB1 receptors and continually prevented HMGB1-induced proinflammatory mechanisms by blocking transcription of nuclear factor-kappa B and synthesis of tumor necrosis factor-alpha. In conclusion, JB demonstrated preventive effects against inflammatory pathologies and showed the potential to be a candidate substance for various inflammatory diseases by regulating HMGB1-mediated cellular signaling. | Kim, Nayeon; Kim, Chaeyeong; Ryu, Soo Ho; Bae, Jong-Sup | Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Dept Pharm, Daegu, South Korea; Kyungpook Natl Univ, Dept Pharm, Coll Pharm, 80 Daehak Ro, Daegu 41566, South Korea | Bae, Jong-Sup/AAU-9724-2020 | 57226179942; 57418696700; 57418127000; 16021543200 | baejs@knu.ac.kr; | JOURNAL OF MEDICINAL FOOD | J MED FOOD | 1096-620X | 1557-7600 | 26 | 1 | SCIE | CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 1.7 | 70.2 | 1.26 | 2025-06-25 | 6 | 6 | barrier integrity; endothelium; HMGB1; Jujuboside B; LPS | LATE MEDIATOR; HMGB1; ACTIVATION; OXIDATION; EXPRESSION; ADHESION; RECEPTOR; RELEASE; DANGER; HMG-1 | barrier integrity; endothelium; HMGB1; Jujuboside B; LPS | Animals; Cell Movement; HMGB1 Protein; Human Umbilical Vein Endothelial Cells; Humans; Lipopolysaccharides; Mice; Mice, Inbred C57BL; Sepsis; advanced glycation end product; cell adhesion molecule; endotoxin; high mobility group B1 protein; immunoglobulin enhancer binding protein; jujuboside b; lipopolysaccharide; natural product; pattern recognition receptor; tumor necrosis factor; unclassified drug; high mobility group B1 protein; jujube extract; jujuboside B; lipopolysaccharide; animal experiment; animal model; animal tissue; antioxidant activity; Article; cell adhesion; cell viability; competitive ELISA; controlled study; endothelium cell; human; human cell; hyperlipidemia; hypoxia; in vitro study; inflammation; leukocyte; male; medicinal plant; mouse; neutrophil; nonhuman; plant seed; thrombocyte aggregation; transendothelial and transepithelial migration; umbilical vein endothelial cell; Zizyphi spinosi semen; animal; C57BL mouse; cell motion; metabolism; sepsis | English | 2023 | 2023-01-01 | 10.1089/jmf.2022.k.0099 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Pomegranate-Derived Exosome-Like Nanovesicles Alleviate Binge Alcohol-Induced Leaky Gut and Liver Injury | Alcoholic liver disease (ALD) is damage to the liver and mainly caused by binge alcohol. ALD have decreased junctional protein expression and modulated intestinal permeability. We investigated whether plant-releasing exosome-like nanovesicles can prevent liver damage and leaky gut from binge alcohol. In this study, we characterized the exosome-like nanovesicles from pomegranate juice and confirmed the round shape of a lipid bilayer. After 14 days of pomegranate-derived exosome-like nanovesicle (PNVs) pretreatment, binge alcohol (6 g/kg/dose) was administered to mice three times orally every 12 h. Exposure to binge alcohol increased levels of oxidative and nitric oxide stress marker proteins such as CYP2E1, 3-Nitrotyrosine, and inducible nitric oxide synthase in both liver and gut damage. Also, binge alcohol significantly elevated the plasma endotoxemia, inflammatory fatty liver, and leaky gut. However, PNVs reduced the oxidative stress and apoptosis marker proteins and prevented the leaky gut and endotoxemia. Markedly, PNV treatment significantly prevented a decrease in the amount of intestinal junctional proteins and an increase in leaky gut in mice exposed to alcohol. These results showed that PNVs can prevent leaky gut and liver damage caused by binge alcohol and suggest that it may be useful hepatoprotective or intestinal protective agents for the first time. | Kim, Ji-Su; Kim, Dong-ha; Gil, Myung-Chul; Kwon, Hyo-Jung; Seo, Wonhyo; Kim, Do-Kyun; Cho, Young-Eun | Andong Natl Univ, Dept Food & Nutr, Andong 36729, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, CMRI, Daegu, South Korea; PLUTO Inc, Seongnam Si, South Korea; Chungnam Natl Univ, Dept Vet Pathol, Coll Vet Med, Daejeon, South Korea; Ewha Womans Univ, Grad Sch Pharmaceut Sci, Coll Pharm, Seoul 03760, South Korea; Jeonbuk Natl Univ, Korea Zoonosis Res Inst, Iksan 54531, South Korea | kim, david/AAA-4537-2020; Kim, Dongha/HNO-9659-2023; Wang, Xiaolin/ADQ-6971-2022 | 59116401000; 57219014701; 58174321500; 56658978200; 56335935100; 57442742600; 56390104900 | wonhyoseo@ewha.ac.kr;dkkim714@jbnu.ac.kr;yecho@anu.ac.kr; | JOURNAL OF MEDICINAL FOOD | J MED FOOD | 1096-620X | 1557-7600 | 26 | 10 | SCIE | CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 1.7 | 70.2 | 2.73 | 2025-06-25 | 11 | 13 | binge alcohol; gut leakiness; liver inflammation; plant-releasing exosome-like nanovesicles (PENs); pomegranate-derived exosome-like nanovesicles (PNVs) | INFLAMMATION; DYSBIOSIS; EXTRACT | binge alcohol; gut leakiness; liver inflammation; plant-releasing exosome-like nanovesicles (PENs); pomegranate-derived exosome-like nanovesicles (PNVs) | 3 nitrotyrosine; alanine aminotransferase; alpha tubulin; aspartate aminotransferase; beta catenin; claudin 4; cyclooxygenase 2; cytochrome P450 2E1; endotoxin; glyceraldehyde 3 phosphate dehydrogenase; inducible nitric oxide synthase; occludin; toll like receptor 4; triacylglycerol; uvomorulin; animal cell; animal experiment; animal tissue; apoptosis; Article; binge drinking; bioluminescence; controlled study; endotoxemia; exosome; fatty liver; female; immunofluorescence; in vitro study; intestine injury; lipid bilayer; liver cell; liver injury; liver protection; male; mouse; nonhuman; oxidative stress; polyacrylamide gel electrophoresis; pomegranate juice; protein purification; real time polymerase chain reaction; small intestine tissue; transmission electron microscopy | English | 2023 | 2023-09-21 | 10.1089/jmf.2023.k.0060 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The Effect of Apple-Derived Nanovesicles on the Osteoblastogenesis of Osteoblastic MC3T3-E1 Cells | Osteoporosis is characterized by low bone mass and elevated structural deterioration of the bone tissue, resulting in bone weakness with an increased risk of fracture. Considering biological activities of various phytochemicals extracted from apples, we herein demonstrated the potential antiosteoporotic effects of apple-derived nanovesicles (apple NVs) using osteoblastic MC3T3-E1 cells. Apple NVs significantly stimulated the growth of MC3T3-E1 cells. The cellular alkaline phosphatase (ALP) activity was significantly upregulated in the 5 mu g/mL apple NVs-treated group. In addition, the concentrarion of mineralized nodules was significantly increased in the apple NVs-treated groups. Furthermore, apple NVs increased the expression of the genes and proteins associated with osteoblast growth and differentiation, such as Runx2, ALP, OPN, and BMP2/4, which further activated ERK- and JNK-related mitogen-activated protein kinase signaling. These results demonstrate that apple NVs have a potential to prevent osteoporosis by promoting osteoblastogenesis in osteoblastic MC3T3-E1 cells through regulating the BMP2/Smad1 pathways. | Sim, Yejin; Seo, Hyun-Ju; Kim, Dong-ha; Lee, Sang-Hoon; Kwon, JaeHee; Kwun, In-Sook; Jung, Chuleui; Kim, Jee-In; Lim, Jae-Hwan; Kim, Do-Kyun; Baek, Moon-Chang; Cho, Young-Eun | Andong Natl Univ, Dept Food & Nutr, Andong, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, CMRI, Daegu, South Korea; Andong Natl Univ, Agr Sci & Technol Res Inst, Andong, South Korea; Andong Natl Univ, Dept Plant Med, Andong, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biochem & Cell Biol, Daegu, South Korea; Andong Natl Univ, Dept Biol Sci, Andong, South Korea; Andong Natl Univ, Inst Vaccine Biotechnol, Andong, South Korea; Jeonbuk Natl Univ, Korea Zoonosis Res Inst, Iksan, Jeonbuk, South Korea; Jeonbuk Natl Univ, Korea Zoonosis Res Inst, Iksan 54531, Jeonbuk, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, CMRI, Daegu 41944, South Korea; Andong Natl Univ, Dept Food & Nutr, Andong 36729, South Korea | Kim, Jong/G-7779-2012; Jung, Chuleui/AAJ-7220-2020; Seo, Hyun-Ju/KVZ-1630-2024 | 57220600274; 57219941260; 57219014701; 58067536200; 58022958600; 6602312720; 7402016268; 59088720100; 17035476100; 57442742600; 7006013097; 56390104900 | dkkim714@jbnu.ac.kr;mcbaek@knu.ac.kr;yecho@anu.ac.kr; | JOURNAL OF MEDICINAL FOOD | J MED FOOD | 1096-620X | 1557-7600 | 26 | 1 | SCIE | CHEMISTRY, MEDICINAL;FOOD SCIENCE & TECHNOLOGY;NUTRITION & DIETETICS | 2023 | 1.7 | 70.2 | 2.94 | 2025-06-25 | 16 | 14 | BMP2; Smad1 signaling pathway; bone mineralization; MAPK signaling pathway; osteoporosis; plant-derived nanovesicles; polyphenols | IN-VITRO DIFFERENTIATION; STEM-CELLS; BONE; POLYPHENOLS; PLANT; NANOPARTICLES; HEALTH; TARGET; GROWTH; MODEL | BMP2/Smad1 signaling pathway; bone mineralization; MAPK signaling pathway; osteoporosis; plant-derived nanovesicles; polyphenols | Bone Morphogenetic Protein 2; Cell Differentiation; JNK Mitogen-Activated Protein Kinases; Malus; Osteoblasts; Osteoporosis; Signal Transduction; alkaline phosphatase; apple nanovesicle; bone morphogenetic protein 2; bone morphogenetic protein 4; calcium; collagen; mitogen activated protein kinase; osteopontin; plant extract; stress activated protein kinase; transcription factor RUNX2; unclassified drug; bone morphogenetic protein 2; stress activated protein kinase; animal cell; animal experiment; antiosteoporotic activity; apple; Article; cell differentiation; cell proliferation; collagen synthesis; controlled study; enzyme activity; gene expression; Malus pumila Mill; MAPK signaling; MC3T3-E1 cell line; mouse; nonhuman; ossification; osteoblast; protein expression; tissue distribution; upregulation; genetics; Malus; metabolism; osteoblast; osteoporosis; signal transduction | English | 2023 | 2023-01-01 | 10.1089/jmf.2022.k.0094 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Youth Authoritarianism in Korean Democracy: What Makes the Youth in a Consolidated Democracy Withdraw Support for Democracy?* | Why do young adults in Korea appear to reject the democratic system and embrace with authoritarianism ? Employing a specially designed survey, this study examined the influence of the models of extreme economic hardship, social threat, fairness, and populism using the structural equation model. Thus, the determinants of the authoritarian system were found to be multidimensional and somewhat at odds with each other in the direction of causation. The threat of economic hardship and intolerant attitudes toward North Korea and minorities were important factors that led young adults to support authoritarian regimes. Nevertheless, young adults who are critical of the fairness of democracy in Korea continue to support the democratic system. Young adults who are critical of representative democracy and oriented toward populism showed the same preference. This result provides the hopeful prospect that Korea may not join the recent trend of deconsolidation and further reauthoritarianism in the near future. | Kang, WooJin | Kyungpook Natl Univ, Daegu, South Korea | Kang, WooJin/AGU-8279-2022 | 55611809600 | nomadwj@gmail.com; | KOREA OBSERVER | KOREA OBS | 0023-3919 | 54 | 4 | SSCI | AREA STUDIES;INTERNATIONAL RELATIONS | 2023 | 0.3 | 70.2 | 0 | 2025-06-25 | 0 | 0 | Authoritarianism; Populism; Economic Hardship; Social Threat; Korean Youth | SENSITIVE QUESTIONS; REGIME SUPPORT; THREAT; CONSEQUENCES; POPULISM; VALUES | Authoritarianism; Economic Hardship; Korean Youth; Populism; Social Threat | English | 2023 | 2023 | 10.29152/koiks.2023.54.4.585 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
