| ○ | ○ | Article | Biomechanical analysis for total distalization of the maxillary dentition: A finite element study | Introduction: This study aimed to identify the tooth movement patterns relative to various force angulations (FAs) when distalizing the total maxillary dentition. Methods: Long-term orthodontic movement of the maxillary dentition was simulated by accumulating the initial displacement of teeth produced by elastic deflection of the periodontal ligament using a finite element analysis. Distalization forces of 3 N were applied to the archwire between the maxillary canine and first premolar at 5 different FAs (-30 degrees, -15 degrees, 0 degrees, 15 degrees, and 30 degrees) to the occlusal plane. Results: Maxillary incisors and molars showed lingual and distal tipping at all FAs, respectively. At a force angulation of 30 degrees, almost bodily distalization of the total maxillary dentition occurred, but incisors showed considerable lingual tipping because of the effect of clearance gap (0.003-in, 0.022 x 0.025-in bracket slot, 0.019 x 0.025-in archwire) and elastic deflection of the archwire. Medial displacement of the maxillary anterior teeth occurred because of lingual tipping during distalization. The occlusal plane rotated clockwise at all FAs because of extrusion of the maxillary incisors and intrusion of the maxillary second molars, and the amounts decreased as FA increased. Conclusions: Tooth movement patterns during distalization of the total maxillary dentition were recognized. With an understanding of the mechanics, a proper treatment plan can be established. | Kawamura, Jun; Park, Jae Hyun; Kojima, Yukio; Tamaya, Naohiko; Kook, Yoon-Ah; Kyung, Hee-Moon; Chae, Jong-Moon | AT Still Univ, Postgrad Orthodont Program, Arizona Sch Dent & Oral Hlth, Mesa, AZ 85206 USA; Kyung Hee Univ, Grad Sch Dent, Seoul, South Korea; Catholic Univ Korea, Dept Orthodont, Seoul St Marys Hosp, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea; Wonkwang Univ, Dept Orthodont, Sch Dent, Wonkwang Dent Res Inst, Iksan, South Korea | Park, Jae/ABI-8037-2020; Kawamura, Jun/N-9465-2018; Chae, Jong-Moon/AAK-6624-2020 | 55366122200; 58370073300; 8385924300; 57205468954; 7006332057; 7004292284; 14035042600 | jongmoon@wku.ac.kr; | AMERICAN JOURNAL OF ORTHODONTICS AND DENTOFACIAL ORTHOPEDICS | AM J ORTHOD DENTOFAC | 0889-5406 | 1097-6752 | 160 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 2.711 | 53.8 | 3.51 | 2025-07-30 | 19 | 23 | TOTAL ARCH DISTALIZATION; DISTAL MOVEMENT; MINISCREW ANCHORAGE; MOLAR DISTALIZATION; EXTRACTION; PATTERN; PLATE; JET | Dentition; Finite Element Analysis; Incisor; Maxilla; Tooth Movement Techniques; article; finite element analysis; first premolar; incisor; maxillary canine; maxillary second molar; orthodontic tooth movement; periodontal ligament; dentition; finite element analysis; maxilla | English | 2021 | 2021-08 | 10.1016/j.ajodo.2020.04.029 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Biomechanical analysis for total mesialization of the maxillary dentition: A finite element study | Introduction: The purpose of this study was to analyze and clarify tooth movement during mesialization of the whole maxillary dentition with various force angulations (FAs). Methods: A finite element method was used to simulate the long-term orthodontic movement of the maxillary dentition by accumulating the initial displacement of teeth produced by elastic deformation of the periodontal ligament. A mesial force of 3 N was applied to the maxillary second molar at 5 different FAs (30 degrees, -15 degrees, 0 degrees, 15 degrees, and 30 degrees) to the occlusal plane. Results: At an FA of 28 degrees, the line of action of the force passed through the center of resistance of the maxillary whole dentition. With all FAs, the central incisors and molars tipped labially and mesially, respectively. The tipping angles gradually decreased as the FAs shifted from -30 degrees to 30 degrees. The molars tipped lingually with FAs of -30 degrees and -15 degrees, whereas they tipped buccally with FAs of 0 degrees, 15 degrees, and 30 degrees. The molars tended to rotate mesiolingually more as the angle of force increased toward an FA of 30 degrees. The occlusal plane rotated counterclockwise with FAs of -30 degrees, -15 degrees, and 0 degrees, whereas it rotated clockwise with FAs of 15 degrees and 30 degrees. With an FA of 30 degrees, buccal tipping and mesiolingual rotation of the molars, and the change in the occlusal plane angle decreased when the transpalatal arch (TPA) was fixed to the first molars and decreased, even more when the TPA was fixed to the second molars rather than the first molars, when a thicker TPA was used, and when the TPA was fixed to both molars rather than a single molar. Conclusions: There was a correlation between tooth movement during mesialization of the whole maxillary dentition and the angle at which the force was applied. | Kawamura, Jun; Park, Jae Hyun; Kojima, Yukio; Tamaya, Naohiko; Kook, Yoon-Ah; Kyung, Hee-Moon; Chae, Jong-Moon | AT Still Univ, Arizona Sch Dent & Oral Hlth, Postgrad Orthodont Program, Mesa, AZ USA; Kyung Hee Univ, Grad Sch Dent, Seoul, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Dept Orthodont, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea; Wonkwang Univ, Wonkwang Dent Res Inst, Sch Dent, Dept Orthodont, Iksan, South Korea | Kawamura, Jun/N-9465-2018; Park, Jae/ABI-8037-2020; Chae, Jong-Moon/AAK-6624-2020 | 55366122200; 58370073300; 8385924300; 57205468954; 7006332057; 7004292284; 14035042600 | jongmoon@wku.ac.kr; | AMERICAN JOURNAL OF ORTHODONTICS AND DENTOFACIAL ORTHOPEDICS | AM J ORTHOD DENTOFAC | 0889-5406 | 1097-6752 | 159 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 2.711 | 53.8 | 1.17 | 2025-07-30 | 7 | 7 | INTERMAXILLARY ELASTICS; SKELETAL ANCHORAGE; PROTRACTION; LOOP; MALOCCLUSION; TRACTION; FORCE | Dentition; Finite Element Analysis; Humans; Maxilla; Molar; Tooth; Tooth Movement Techniques; dentition; finite element analysis; human; maxilla; molar tooth; orthodontic tooth movement; tooth | English | 2021 | 2021-06 | 10.1016/j.ajodo.2020.02.021 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Comparison of Quality Characteristics and Palatability between Sous-Vide Cooked Pork Loin Patties with Different Searing Treatments | This study compared the quality, cooking, textural, and palatability characteristics between sous-vide (SV) cooked pork loin patties with different searing treatments (ST). Before SV cooking, STs were conducted on each side of the pork loin patties for 0 (control) to 120 s (ST120), and all patties were then cooked using an SV cooker at 75 degrees C for 120 min. Noticeable differences were observed in quality properties between the groups. The seared SV loin patties exhibited lower lightness and higher browning index values compared to the unseared SV loin patties (p<0.001). Cooking loss gradually increased with increasing ST times, and the control group had a lower percentage compared to the ST60 group (19.5 vs. 25.7%, p<0.001). Changes in cooking properties were associated with the extent of ST, and the ST groups exhibited a higher hardness value compared to the control group (p<0.001). Regarding palatability, loin patties from the control group scored lower in appearance acceptability compared to patties from the ST groups (p<0.05) due to extent of browning on the surface. Moreover, the ST groups did exhibit a higher flavor intensity compared to the control group, but no differences were observed in tenderness and juiciness scores between the control and ST60 groups. Due to these results, the ST60 group exhibited a greater score in overall acceptability compared to the other groups except for the ST90 group. Therefore, an additional ST before SV cooking can achieve a more appealing appearance and palatability as well as to enhance the availability of pork loin. | Cho, Dong Kook; Lee, Boin; Kim, Song Ki; Hyeonbin, O.; Kim, Young Soon; Choi, Young Min | Korea Univ, Dept Integrated Biomed & Life Sci, Seoul 02841, South Korea; Hotel Lotte, Dept Culinary, Seoul 04533, South Korea; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea | ; Choi, Young/J-6027-2014; Kim, Kyoungmi/AEP-3965-2022 | 54400741900; 57218130871; 57222636214; 57192907291; 57196173426; 57226673843 | ymchoi1@knu.ac.kr; | FOOD SCIENCE OF ANIMAL RESOURCES | FOOD SCI ANIM RESOUR | 2636-0772 | 2636-0780 | 41 | 2 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2021 | 3.135 | 53.8 | 0.69 | 2025-07-30 | 7 | 7 | sous-vide cooking; searing treatment; quality characteristics; sensory quality; pork loin | SENSORY CHARACTERISTICS; MEAT; GRADES; MUSCLE | Pork loin; Quality characteristics; Searing treatment; Sensory quality; Sous-vide cooking | English | 2021 | 2021 | 10.5851/kosfa.2020.e90 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Does maxillary yaw exist in patients with skeletal Class III facial asymmetry? | Introduction: This study aimed to evaluate maxillary skeletal and dental yaw in patients with skeletal Class III facial asymmetry and investigate its correlation with menton deviation. Methods: Initial cone-beam computed tomography data from 60 patients with skeletal Class III malocclusion were used. There were 30 patients in both the symmetrical group (menton deviation 4 mm). After reconstruction of 3-dimensional (3D) cone-beam computed tomography data, maxillary yaw and 3D positions of skeletal and dental landmarks were measured and compared between the groups. After that, correlations between menton deviation and the other variables were assessed. Results: No significant difference was noted in maxillary skeletal and dental yaw between the 2 groups. In the assessment of 3D positions, translation of the maxillary bone and maxillary dentition toward the menton deviation was observed (P<0.01). Maxillary skeletal and dental yaw was not significantly correlated with menton deviation in the asymmetrical group. Conclusions: Maxillary skeletal and dental yaw was not evident in either group. Therefore, when planning maxillary surgery for patients with skeletal Class III facial asymmetry malocclusion, it may be appropriate to shift the focus of decompensation from maxillary yaw to maxillary translation. | Noh, Hyung-Kyu; Park, Hyo-Sang | Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Dalgubuldaero 2175,Samduk 2 Ga, Daegu 41940, South Korea | 57208229164; 55754836800 | parkhs@knu.ac.kr; | AMERICAN JOURNAL OF ORTHODONTICS AND DENTOFACIAL ORTHOPEDICS | AM J ORTHOD DENTOFAC | 0889-5406 | 1097-6752 | 160 | 4 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 2.711 | 53.8 | 1.37 | 2025-07-30 | 10 | 8 | AIDED SURGICAL SIMULATION; BEAM COMPUTED-TOMOGRAPHY; ORTHOGNATHIC SURGERY; MAXILLOMANDIBULAR COMPLEX; 3-DIMENSIONAL ANALYSIS; DENTAL COMPENSATION; 3D-CT EVALUATION; DEVIATION; CASS; CLASSIFICATION | English | 2021 | 2021-10 | 10.1016/j.ajodo.2020.05.025 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Effects of Astragalus membranaceus, Adenophora triphylla, and Ulmus pumila Extracts on Quality Characteristics and Storage Stability of Sous-Vide Cooked Chicken Breasts | This study aimed to investigate the influence of Astragalus membranaceus (AM), Adenophora triphylla (AT), and Ulmus pumila (UP) extracts on the quality traits, palatability, and storage stability of sous-vide (SV) cooked chicken breasts. Chicken breasts were marinated in AM, AT, or UP extracts for 1 h, and then consistently cooked at a constant temperature of 60. for 2 h. SV cooked chicken breasts with the UP extract exhibited lower lightness and higher yellowness values on the surface region compared to those with the AM and AT extracts (p0.05), although the UP group had lower color acceptability (p0.05). Owing to these results regarding overall sensory acceptability, samples from the UP group were more preferred by the trained panelists compared to samples from the control group (p<0.001). On 14 d of cold storage, all the groups with herbal medicinal extracts exhibited a lower concentration of thiobarbituric acid-reactive substances than the control group (p<0.05), and the AT and UP groups showed lower values compared to the AM group due to their higher flavonoid contents (p<0.001). Therefore, meat marination with herbal plant extracts before SV cooking can be effective for enhancing the overall quality of SV cooked chicken breast. | Lee, Boin; Park, Chun Ho; Kim, Jae Yeong; O, Hyeonbin; Kim, Dasol; Cho, Dong Kook; Kim, Young Soon; Choi, Young Min | Kyungpook Natl Univ, Dept Anim Sci AndBiotechnol, Sangju 37224, South Korea; Korea Univ, Dept Integrated Biomed AndLife Sci, Seoul 02841, South Korea; Daejeon Hlth Inst Technol, Dept Hotel & Food Serv Culinary Art, Daejeon 34504, South Korea; Hotel Lotte Co Ltd, Dept Culinary, Seoul 04533, South Korea | ; Choi, Young/J-6027-2014; Kim, Kyoungmi/AEP-3965-2022 | 57218130871; 57216440160; 57226306561; 57192907291; 57226309804; 54400741900; 57196173426; 57226673843 | ymchoi1@knu.ac.kr; | FOOD SCIENCE OF ANIMAL RESOURCES | FOOD SCI ANIM RESOUR | 2636-0772 | 2636-0780 | 41 | 4 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2021 | 3.135 | 53.8 | 0.46 | 2025-07-30 | 4 | 5 | sous-vide cooking; herbal medicinal extracts; quality characteristics; storage stability; chicken breasts | ANTIOXIDANT ACTIVITY; SPICE EXTRACTS; MEAT; PATTIES | Chicken breasts; Herbal medicinal extracts; Quality characteristics; Sous-vide cooking; Storage stability | English | 2021 | 2021 | 10.5851/kosfa.2021.e24 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Prevention of Cholesterol Gallstone Formation by Lactobacillus acidophilus ATCC 43121 and Lactobacillus fermentum MF27 in Lithogenic Diet-Induced Mice | The objective of this study was to evaluate the effects of Lactobacillus acidophilus ATCC 43121 and L. fermentum MF27 on biochemical indices in the serum, cholesterol metabolism in the liver and mucin expression in the gallbladder in lithogenic diet (LD)-induced C57BL/6J mice to determine the preventive effects of lactobacilli on gallstone formation. By the end of 4 wk of the experimental period, mice fed on a LD with high-fat and high-cholesterol exhibited higher levels of total and low-density lipoprotein cholesterol in the serum compared to mice fed on control diet or LD with L. acidophilus ATCC 43121 (LD+P1; p<0.05). Cholesterol-lowering effects observed in the LD+P1 and LD with L. fermentum MF27 (LD+P2) groups were associated with reduced expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase in the liver compared to the LD group (p<0.05). Furthermore, expression of the gel-forming mucin, including MUC5AB and MUC5B, was suppressed in the LD+P1 and LD+P2 groups compared to the LD group (p<0.05). Therefore, steady intake of both L. acidophilus ATCC 43121 and L. fermentum MF27 may have the ability to prevent the formation of cholesterol gallstones in LD-induced C57BL/6J mice. | Oh, Ju Kyoung; Kim, You Ra; Lee, Boin; Choi, Young Min; Kim, Sae Hun | Korea Univ, Dept Food Biosci & Technol, Seoul 02841, South Korea; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea | Choi, Young/J-6027-2014; Kim, Sin Gon/KQU-7757-2024 | 57216425725; 57222634035; 57218130871; 57226673843; 7601601647 | ymchoi1@knu.ac.kr;saehkim@korea.ac.kr; | FOOD SCIENCE OF ANIMAL RESOURCES | FOOD SCI ANIM RESOUR | 2636-0772 | 2636-0780 | 41 | 2 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2021 | 3.135 | 53.8 | 1.03 | 2025-07-30 | 11 | 12 | cholesterol gallstone; mucin; Lactobacillus acidophilus; Lactobacillus fermentum; lithogenic diet | EICOSAPENTAENOIC ACID; GALLBLADDER BILE; DISEASE; CELLS | Cholesterol gallstone; Lactobacillus acidophilus; Lactobacillus fermentum; Lithogenic diet; Mucin | English | 2021 | 2021 | 10.5851/kosfa.2020.e93 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sensory Quality and Histochemical Characteristics of Longissimus Thoracis Muscles between Hanwoo and Holstein Steers from Different Quality Grades | This study compared the meat quality characteristics, palatability, and histochemical characteristics of low-marbled Hanwoo and Holstein steers of different beef quality grades (1, 2, and 3). No differences were observed in muscle pH(24 h) and cooking loss between the groups (p>0.05); however, quality grade 1 of Hanwoo steers (HA1) showed a darker muscle surface compared to grade 1 of Holstein steers (HO1) (30.9 vs. 33.9, p0.05). This difference in tenderness attributes between the breeds within the quality grade was associated with morphological traits of muscle bundle, and Hanwoo steers had smaller bundle area (0.37 vs. 0.50 mm(2), p<0.05) and higher fiber number per bundle (88.2 vs. 121, p<0.05) compared to Holstein steers. Therefore, bundle characteristics of longissimus thoracis muscle can be crucial for explaining factor for the explanation of tenderness variations between different breeds at the same beef quality grade or marbling. | Kim, Jae Yeong; Lee, Boin; Kim, Dong Hwan; Lee, Kichoon; Kim, Eun Joong; Choi, Young Min | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Ohio State Univ, Dept Anim Sci, Columbus, OH 43210 USA | ; Kim, Donghwan/LRC-0840-2024; Lee, Kichoon/G-2234-2012; Kim, Eun Joong/HGF-1639-2022 | 57226306561; 57218130871; 56621562800; 14123395400; 57213620881; 57226673843 | ymchoil@knu.ac.kr;ymchoi1@knu.ac.kr; | FOOD SCIENCE OF ANIMAL RESOURCES | FOOD SCI ANIM RESOUR | 2636-0772 | 2636-0780 | 41 | 5 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2021 | 3.135 | 53.8 | 0.69 | 2025-07-30 | 7 | 6 | sensory quality; muscle bundle; Hanwoo; Holstein; beef quality grade | BEEF QUALITY; CARCASS; TRAITS; BREED; FIBER; TENDERNESS; GROWTH; CATTLE; DAIRY | Beef quality grade; Hanwoo; Holstein; Muscle bundle; Sensory quality | English | 2021 | 2021 | 10.5851/kosfa.2021.e35 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Oxidative removal of sulfadiazine using synthetic and natural manganese dioxides | Studies on oxidation kinetics of sulfadiazine (SDZ) using delta-MnO2 (birnessite) and natural MnO2 are limited. Reaction order at different SDZ speciation was determined based on the effects of initial H+, MnO2 and SDZ concentrations using initial rate method, which would be useful to determine the optimum pH and MnO2 concentration. Birnessite and natural MnO2 with different physico-chemical properties such as BET surface area, pH(PZC), d-spacing, and crystal size similarly showed good efficiencies in oxidizing neutral SDZ (pH 5) and anionic SDZ (pH 8). Activation energy (E-a) and thermodynamic parameters indicated the similar oxidation efficiencies in the temperature range of 10-40 degrees C. The was produced from the SDZ oxidation coupled to the reduction of MnO2 to Mn2+. The effect of co-solute ciprofloxacin (CIP) on the oxidation kinetics of SDZ was also studied. The rates of SDZ oxidation by both birnessite and natural MnO2 were reduced by the presence of CIP due to competition in oxidation between SDZ and CIP. The SDZ was more rapidly oxidized than CIP in both single- and bi-solute systems, as indicated by the presence of CIP intermediate, whereas the intermediate of SDZ was not detected.

| ○ | ○ | Article | The modified Song isotherm model: application to multisolute sorption of phenols in organoclays using the ideal adsorbed solution theory | The three-parameter (K, b, and n) Song isotherm model was slightly modified to make it possible to obtain analytical integration of the spreading pressure integral. The modified Song model (MSM) allows more efficient and accurate calculation of the ideal adsorbed solution theory (IAST). The MSM also satisfies the Henry?s law and the Freundlich model at low and high concentrations, respectively, and reverts to the Langmuir and the linear models when n equals zero and one, respectively. Approximate values of each parameter could be estimated from a plot of log (q/c) versus log c; the partition coefficient in the Henry?s law region (K) and the Freundlich index (n) can be estimated from the ordinate value of the low-concentration asymptote and the slope of the high-concentration asymptote, respectively, and the parameter (b) can be estimated from the solution-phase concentration of the intersection point of the two asymptotes. The MSM was fitted to the single-solute sorption of 2-chloro-, 3-cyano-, and 4-nitrophenol onto montmorillonites modified with either HDTMA cation or TMA/HDTMA dual cations. The ideal adsorbed solution theory (IAST) combined with either dual-mode model, Khan model or MSM as a single-solute isotherm model was used to predict three bisolute and one trisolute sorption to organoclays. The Sheindorf-Rebhun-Sheintuch (SRS) and Murali-Aylmore (M-A) were also used to predict bisolute sorption to organoclays. The IAST predictions were generally in good agreement with the multisolute sorption data. The advantages of MSM over other three-parameter models were fully discussed. | Song, Dong-Ik; Choi, Jiyeon; Shin, Won Sik | Kyungpook Natl Univ, Dept Chem Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu, South Korea | 7402443648; 57211707591; 23019870800 | wshin@mail.knu.ac.kr; | ENVIRONMENTAL TECHNOLOGY | ENVIRON TECHNOL | 0959-3330 | 1479-487X | 42 | 10 | SCIE | ENVIRONMENTAL SCIENCES | 2021 | 3.475 | 53.9 | 0.11 | 2025-07-30 | 6 | 3 | Competition modelling; ideal adsorbed solution theory (IAST); modified Song isotherm model; organoclay; spreading pressure | MULTICOMPONENT ADSORPTION EQUILIBRIA; DISTRIBUTED REACTIVITY MODEL; COMPETITIVE ADSORPTION; ACTIVATED CARBON; ORGANIC-COMPOUNDS; AQUEOUS-SOLUTION; SOILS; THERMODYNAMICS; WATER; MONTMORILLONITE | Competition modelling; ideal adsorbed solution theory (IAST); modified Song isotherm model; organoclay; spreading pressure | Adsorption; Bentonite; Cations; Phenols; Solutions; Forecasting; Isotherms; Organoclay; Positive ions; phenol derivative; bentonite; cation; Accurate calculations; Analytical integration; Ideal adsorbed solution theories (IAST); Ideal adsorbed solution theory; Isotherm modeling; Partition coefficient; Single solute sorption; Three-parameter models; isotherm; numerical model; partition coefficient; phenol; sorption; chemical analysis; concentration (parameter); isotherm; mathematical model; measurement accuracy; adsorption; solution and solubility; Sorption | English | 2021 | 2021-04-29 | 10.1080/09593330.2019.1674929 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of In-Situ Silicon Carbon Nitride (SiCN) Cap Layer on Performances of AlGaN/GaN MISHFETs | AlGaN/GaN metal insulator semiconductor heterostructure field effect transistors (MISHFETs) with different thickness of in-situ silicon carbon nitride (SiCN) cap layer were investigated. It was found that in-situ SiCN layer not only increases the two dimensional electron gas (2DEG) density, but also effectively passivates the surface of the AlGaN/GaN MISHFET. The fabricated device with 2 nm-thick SiCN cap layer exhibits superior device performances, such as larger maximum transconductance (g(m)) and higher on/off drain-current ratio (I-ON/I-OFF) compared to those of the device without SiCN cap layer. | Lee, Jae-Hoon; Im, Ki-Sik; Lee, Jung-Hee | Samsung Elect Co Ltd, Yield Enhancement Team, Pyeongtack 177786, South Korea; Kumoh Natl Inst Technol, Adv Mat Res Ctr, Gumi 39177, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 56023466800; 8679677600; 57196140713 | jaehoon03.lee@samsung.com; | IEEE JOURNAL OF THE ELECTRON DEVICES SOCIETY | IEEE J ELECTRON DEVI | 2168-6734 | 9 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2021 | 2.523 | 54.2 | 0.22 | 2025-07-30 | 3 | 4 | AlGaN/GaN; metal insulator semiconductor heterostructure field effect transistors (MISHFETs); in-situ silicon carbon nitride (SiCN); cap layer; 2DEG density; surface leakage current | BAND-OFFSET; GAN; PASSIVATION; SIH4; SIN; DENSITY; LEAKAGE; STRAIN | 2DEG density; AlGaN/GaN; cap layer; in-situ silicon carbon nitride (SiCN); metal insulator semiconductor heterostructure field effect transistors (MISHFETs); surface leakage current | Aluminum gallium nitride; Carbon nitride; Density of gases; Drain current; Field effect transistors; Gallium nitride; III-V semiconductors; Metal insulator boundaries; MIS devices; Two dimensional electron gas; Wide band gap semiconductors; AlGaN/GaN MISHFET; Device performance; Different thickness; Fabricated device; Maximum transconductance; Metal-insulator-semiconductors; Silicon carbon nitride; Two-dimensional electron-gas (2DEG) density; Indium compounds | English | 2021 | 2021 | 10.1109/jeds.2021.3100760 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Identification of Central Symptoms in Depression of Older Adults With the Geriatric Depression Scale Using Network Analysis and Item Response Theory | Objective This study aimed to identify the central symptoms of late-life depression using network analysis and the item response theory. Methods A total of 3,472 older adults were enrolled and the Geriatric Depression Scale-15 (GDS-15) was used to evaluate the depressive symptoms. To identify the central symptoms and the network structures among the individual symptoms, the analyses of symptom network structures and item response theory were performed. Results Among items on the GDS-15, "Happy," "Hopeless," "Empty," "Bored," "Worthless," and "Good spirits" showed significantly higher strength centrality than the other symptoms. Among all the edges, the edge between "Empty" and "Bored" was the strongest; however, these two symptoms were not connected strongly to other symptoms. In the analysis of item response theory, "Empty," "Bored," "Hopeless," "Worthless," "Happy," "Helpless," and "Satisfied" presented a very high value on the discrimination parameter. Conclusion Our study identified the central symptoms and the network structures among symptoms listed on the GDS-15. Most of central symptoms identified by network analysis and item response theory coincided. Our results suggest that these central symptoms need to be prioritized as highly comorbid symptoms and can contribute to the development of a brief screening tool for the elderly.

| ○ | ○ | Article | Impact of Sulfur Passivation on Carrier Transport Properties of In0.7Ga0.3As Quantum-Well MOSFETs | We investigated the impact of a sulfur passivation (S-passivation) process step on carrier transport properties of surface-channel In0.7Ga0.3As quantum-well (QW) Metal-Oxide-Semiconductor Field-Effect-Transistors (MOSFETs) with source/drain (S/D) regrowth contacts. To do so, we fabricated long-channel In0.7Ga0.3As QW MOSFETs with and without (NH4)(2)S treatment prior to a deposition of Al2O3 /HfO2 = 1-nm/3-nm by atomic-layer-deposition (ALD). The devices with S-passivation exhibited a lower value of subthreshold-swing (S) = 74 mV/decade and more positive shift in the threshold voltage (V-T) than those without S-passivation. From the perspective of carrier transport, S-passivated devices displayed excellent effective mobility (mu(eff)) in excess of 6,300 cm(2)/V.s at 300 K. It turned out that the improvement of mu(eff )was attributed to reduced Coulombic and surface-roughness scatterings. Using a conductance method, a fairly small value of interface trap density (D-it) = 1.56 x 10(12) cm(-2) eV(-1) was obtained for the devices with S-passivation, which was effective in mitigating the Coulombic scattering at the interface between the high-k dielectric layer and the In0.7Ga0.3As As surface-channel layer. | Kim, Jun-Gyu; Jo, Hyeon-Bhin; Lee, In-Geun; Kim, Tae-Woo; Kim, Dae-Hyun | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Univ Ulsan, Dept Elect Engn, Ulsan 41610, South Korea; Yonsei Univ, Dept Mat Sci & Engn, Seoul 03722, South Korea | Jo, Hyeon Bhin/HLW-9536-2023; Kim, Yong/H-6157-2013; Kim, Junghwan/AAQ-9204-2021 | 57203326312; 57202871742; 37016357200; 57203495132; 57212363794 | twkim78@ulsan.ac.kr;dae-hyun.kim@ee.knu.ac.kr; | IEEE JOURNAL OF THE ELECTRON DEVICES SOCIETY | IEEE J ELECTRON DEVI | 2168-6734 | 9 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2021 | 2.523 | 54.2 | 0.22 | 2025-07-30 | 3 | 4 | In0.7Ga0.3As; MOSFET; passivation; carrier scattering mechanism; interface trap density; effective mobility | GATE; DEPENDENCE; CHANNEL | carrier scattering mechanism; effective mobility; In<sub>0.7</sub>Ga<sub>0.3</sub>; interface trap density; MOSFET; passivation | Alumina; Aluminum oxide; Atomic layer deposition; Carrier transport; Hall mobility; High-k dielectric; Hole mobility; Indium alloys; Metals; MOS devices; MOSFET devices; Oxide semiconductors; Passivation; Quantum chemistry; Semiconductor alloys; Semiconductor quantum wells; Surface roughness; Surface scattering; Threshold voltage; Transport properties; Conductance method; Effective mobilities; High-k dielectric layers; Interface trap density; Subthreshold swing; Sulfur passivation; Surface channel; Surface roughness scattering; Gallium alloys | English | 2021 | 2021 | 10.1109/jeds.2021.3056689 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Korean Version of the Thought-Action Fusion Scale: The Evidence for Its Psychometric Properties | Objective The Thought-Action Fusion Scale (TAFS) is a self-reported instrument used to measure a cognitive bias, namely, thought-action fusion (TAF), in which intrusive thoughts have moral and actual consequences. The aim of this study is to investigate the reliability and validity of the Korean version of the 19-item TAFS (K-TAFS) in Korean samples. Methods In this study, 628 university students and 93 patients with obsessive-compulsive disorder (OCD) completed the K-TAFS and several other psychological scales. Descriptive analyses, correlations, group comparisons, and exploratory and confirmatory factor analyses were performed. Results The results of the exploratory and confirmatory factor analyses indicated a two-factor structure with TAF-Morality and TAF-Likelihood that best fits the data in the university sample. The reliability analyses showed that TAFS and its factors had excellent internal consistencies. Regarding the concurrent validity, positive correlations were observed between TAF-Likelihood and cognitive fusion, while the TAFS scores did not show any consistent correlations with other symptoms such as depression and anxiety. Compared to the university students, the OCD patients showed higher TAFS scores and their obsessive-compulsive symptoms were significantly associated with both TAF-Morality and TAF-Likelihood. Conclusion Overall, the findings of this study support the reliability and validity of the K-TAFS. | Lee, Seung Jae; Lee, Soonhee | Kyungpook Natl Univ, Sch Med, Dept Psychiat, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea; Univ Maryland Baltimore Cty UMBC, Counseling Ctr, Baltimore, MD USA | Lee, Seung/AAI-1191-2020; Lee, Soonhee/MEP-6769-2025 | 58509400200; 57196198003 | jayleemd@knu.ac.kr; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1738-3684 | 1976-3026 | 18 | 4 | SCIE;SSCI | PSYCHIATRY | 2021 | 3.202 | 54.2 | 0.45 | 2025-07-30 | 7 | 7 | Thought-action fusion; Thought-Action Fusion Scale; Obsessive-compulsive disorder; Cognitive bias; Psychometric properties | OBSESSIVE-COMPULSIVE DISORDER; COGNITIVE FUSION; GENDER-DIFFERENCES; ANXIETY; MODEL; RESPONSIBILITY; SPECIFICITY; VALIDATION; AVOIDANCE; INVENTORY | Cognitive bias; Obsessive-compulsive disorder; Psychometric properties; Thought-action fusion; Thought-action fusion scale | action potential; alcoholism; anxiety; Article; Beck Anxiety Inventory; Beck Depression Inventory; concurrent validity; confirmatory factor analysis; criterion related validity; Cronbach alpha coefficient; depression; disease severity; diseases; exploratory factor analysis; exploratory research; head injury; human; intellectual impairment; internal consistency; Korean (people); major depression; maximum likelihood method; neurologic disease; obsessive compulsive disorder; outpatient department; principal component analysis; psychiatry; psychological rating scale; psychometry; psychosis; questionnaire; reliability; risk; schizophrenia spectrum disorder; structure activity relation; thought action fusion; traffic accident; validity | English | 2021 | 2021-04 | 10.30773/pi.2020.0396 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Reconciliation of Two Cognitive Models in Obsessive-Compulsive Disorder: An fMRI Study | Objective: Although cognitive models of obsessive-compulsive disorder (OCD) fall into two categories: cognitive deficit models and dysfunctional belief models, these approaches have their own ways and have hardly been reconciled. Therefore, this study aimed to investigate the potential relationships between cognitive deficit (using the Wisconsin Card Sorting Task, WCST) and dysfunctional belief (measured by scales of dysfunctional beliefs) mediated by neural activity in OCD patients. Methods: Thirty OCD patients and 30 healthy participants performed the WCST condition and a baseline MATCH condition during the 3T-functional magnetic resonance imaging (fMRI) acquisition. Results: Engagement of additional frontoparietal networks with poorer performance of WCST was found during the fMRI scan in OCD patients. Selected regions of interest from activated regions have positive relationships with dysfunctional beliefs and with the unacceptable thoughts symptom dimension in the OCD group. Conclusion: Findings suggest that alteration in frontoparietal networks related to cognitive deficits can be associated with dysfunctional beliefs while performing conventional neurocognitive tasks and this association with dysfunctional beliefs may be pronounced in the unacceptable thoughts domain-dominant OCD patients. | Kim, Seungho; Lee, Sang Won; Cha, Hyunsil; Kim, Eunji; Chang, Yongmin; Lee, Seung Jae | Kyungpook Natl Univ, Dept Med & Biol Engn, Daegu, South Korea; Kyungpook Natl Univ, Dept Psychiat, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Psychiat, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea | Lee, Seung/AAI-1191-2020 | 57218284791; 55820414800; 57189728122; 57215273419; 7501840633; 58509400200 | ychang@knu.ac.kr;jayleemd@knu.ac.kr; | PSYCHIATRY INVESTIGATION | PSYCHIAT INVEST | 1738-3684 | 1976-3026 | 18 | 6 | SCIE;SSCI | PSYCHIATRY | 2021 | 3.202 | 54.2 | 0.08 | 2025-07-30 | 0 | 2 | Cognitive deficit; Executive function; Dysfunctional beliefs; Frontoparietal network; Obsessive-compulsive symptom domain | METAANALYSIS; BRAIN; SELF | Cognitive deficit; Dysfunctional beliefs; Executive function; Frontoparietal network; Obsessive-compulsive symptom domain | adult; Alzheimer disease; Article; attention deficit disorder; autism; Beck Depression Inventory; clinical article; cognition; cognitive defect; cognitive function test; cognitive model; controlled study; depression; disease severity; DSM-5; DSM-IV; electroencephalography; emotion; executive function; female; frontoparietal network; functional magnetic resonance imaging; Hamilton Depression Rating Scale; head injury; human; insula; intellectual impairment; intelligence quotient; language ability; major depression; male; Montreal cognitive assessment; neuropsychological test; nuclear magnetic resonance imaging; obsessive compulsive disorder; prefrontal cortex; psychophysiology; salience network; Wechsler intelligence scale for children; Wisconsin Card Sorting Test; working memory | English | 2021 | 2021-06 | 10.30773/pi.2020.0347 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Relations between quandle extensions and group extensions | In [6] and [7], Joyce and Matveev showed that for given a group G and an automorphism phi, there is a quandle structure on the underlying set of G. When the automorphism is an inner-automorphism by zeta, we denote this quandle structure as (G, Sic(zeta)). In this paper, we show a relationship between group extensions of a group G and quandle extensions of the quandle (G, Sic(zeta)). In fact, there exists a group homomorphism from H-gp(2) (G ; A) to H-q(2) ((G, Sic(zeta)); A). Next, we show a relationship between quandle extensions of a quandle Q and quandle extensions of the quandle on the inner automorphism group of Q. Indeed, there exists a group homomorphism from H-q(2)(Q ; A) to H-q(2) ((Inn(Q), Sic(zeta)); A). Finally, we observe via examples a relationship between extensions of a quandle and extensions of the inner automorphism group of the quandle.
