| ○ | ○ | Article | An insight into the luminescence properties of Ce³⁺ in garnet structured CaY2Al4SiO12:Ce³⁺ phosphor | In this study, CaY2Al4SiO12:xCe(3+) (0.01 <= x <= 0.11) phosphors were prepared by using the sol-gel method. The crystal structure, morphology, and luminescence properties were well studied by means of X-ray diffraction (XRD), UV-vis, scanning electron microscope (SEM), and photoluminescence spectroscopy. The XRD patterns revealed that the CaY2Al4SiO12:xCe(3+) (0.01 <= x <= 0.11) phosphors formed a cubic crystal structure with Ia3d space group, and a = b = c = 12.0089 lattice parameters. The band gap and the particle size of the prepared phosphors, estimated from the UV-vis spectrum and SEM micrograph, were found to be 3.35 eV and (30-100) nm, respectively. The phosphors showed an intense green emission band upon 449 nm excitation with the average color purity value of around 79 %. It is expected that the CaY2Al4SiO12:xCe(3+) (0.01 <= x <= 0.11) phosphors can be used as a green component in the WLEDs application. | Singh, Vijay; Hakeem, D.

| ○ | ○ | Article | Green emitting holmium (Ho) doped yttrium oxide (Y2O3) phosphor for solid state lighting | This paper reports the synthesis of Y2-xHoxO3 phosphor by citrate sol-gel method. Phase purity and morphological studies were performed by X-Ray diffraction (XRD) and scanning electron microscopy (SEM) characterization technique, respectively. Diffuse reflectance (DR) spectrum of the sample was recorded, and the band gap energy was estimated by using Kubelka-Munk (K-M) model. Photoluminescence (PL) studies of the prepared phosphors were carried out in this work. CIE coordinates of the studied phosphor were calculated, and which indicate the green color of the phosphor. The studied phosphor Y2-xHoxO3 exhibits strong green luminescence upon the blue excitation which claims its candidature for solid state lighting applications. | Singh, Vijay; Dabre, K., V; Dhoble, S.

| ○ | ○ | Article | Non-Invasive Optical Screening of Streptococcus Pneumonia Based Inflammatory Changes of the Tympanic Membrane and Mastoid Mucosa in Guinea Pig Otitis Media Using Optical Coherence Tomography | The accurate screening of otitis media (OM) lies in clarifying the numerous confounding and quantitative factors that are discovered during primary inspections. Increased awareness about bacterial biofilms and inflammation has allowed researchers to develop a better understanding of the bacterial infections that occur in the middle ear. In this study, four live guinea pigs were inoculated with Streptococcus pneumonia to induce OM-related inflammatory changes. Since optical techniques have been effectively used for diagnosis in medicine, low-coherence interferometry-based optical coherence tomography (OCT) was employed for depth-resolved high-resolution data screening. Multiple locations of the tympanic membrane (TM), mastoid mucosa, and round window membrane were examined to assess inflammatory changes. We performed qualitative assessments and thickness quantifications and investigated the variations due to adverse inflammatory affects. The findings of the present study provide a better understanding of S. pneumonia bacteria caused inflammatory changes in middle ear and it further provides a fundamental platform for future clinical utility. | Wijesinghe, Ruchire Eranga; Lee, Jaeyul; Jeon, Deokmin; Kim, Pilun; Han, Sangyeob; Lee, Junsoo; Seong, Daewoon; Lee, Dong-Eun; Jang, Jeong Hun; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, Sch Elect Engn, Coll IT Engn, Daegu 41566, South Korea; Ajou Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Gyeunggi Do 41944, South Korea; Kyungil Univ, Dept Biomed Engn, Coll Engn, Gyeongsangbuk Do 38428, South Korea; Kyungil Univ, Coll Smart Engn, Dept Autonomous Robot Engn, Gyeongsangbuk Do 38428, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil Engn, Daegu 41566, South Korea | Lee, Jung Bok/HHZ-3200-2022; Wijesinghe, Ruchire/K-3797-2016; Lee, Junsoo/IUO-9627-2023 | 56018152300; 57188689420; 57204570554; 56967482800; 57193695305; 57209986073; 57212512353; 56605563300; 26639429600; 24171094000; 7601373350 | msjeon@knu.ac.kr; | IEEE PHOTONICS JOURNAL | IEEE PHOTONICS J | 1943-0655 | 1943-0647 | 12 | 4 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;OPTICS;PHYSICS, APPLIED | 2020 | 2.443 | 47.0 | 0.16 | 2025-06-25 | 2 | 2 | OTOSCOPE; BIOFILM | inflammatory changes; mastoid mucosa; Optical coherence tomography; Otitis media; round window membrane; Streptococcus pneumonia; tympanic membrane | Diagnosis; Mammals; Tomography; Bacterial infections; High resolution data; Low coherence interferometry; Optical screening; Optical technique; Qualitative assessments; Quantitative factors; Tympanic membranes; Optical tomography | English | 2020 | 2020-08 | 10.1109/jphot.2020.3012497 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optical and mechanical properties of Li2Mg2(MoO4)3 crystal grown by Czochralski method | A Li2Mg2(MoO4)(3) crystal was grown by self-flux Czochralski method in a platinum crucible. The polycrystalline compound was synthesised using standard solid-state reaction method. The purity of the synthesised compound was analysed through powder X-ray diffraction method. Single crystal growth was carried out using a Czochralski chamber in argon atmosphere and the pulling rate was maintained 0.5 mm/h with a rotation rate of 8-10 rpm. The temperature dependent luminescence and decay time measurements were carried out in a temperature range of 10-300 K. The grown crystal sample exhibits an intrinsic emission band in a wavelength range from 320 to 800 nm with the maximum peak at 590 nm. At low temperatures, a significant increase in emission intensity is observed as well as the red shift in the peak position. The luminescence decay time was fitted with three decay components. Thermally stimulated luminescence glow curve was recorded to study the trap centers and found a trap center at 25 K with 3 meV trap depth. Mechanical behaviour of the grown crystal was analysed by using Vicker's micro hardness testing. The results suggest that Li2Mg2(MoO4)(3) crystal can be used for luminescence applications. | Daniel, D. Joseph; Pandey, Indra Raj; Karuppasamy, P.; Kim, H.

| ○ | ○ | Article | Overgrowth of the Femur After Internal Fixation in Children With Femoral Shaft Fracture-A Multicenter Study | Objectives: To evaluate overgrowth after internal fixation for pediatric femur fracture and to identify any factors related with overgrowth in terms of fracture type and fixation method. Design: Retrospective comparative study. Setting: Multicenter, children's hospital and general hospital. Patients/Participants: Eighty-seven children between 4 and 10 years of age were included. Length-stable fracture was noted in 49 children, and length-unstable fracture was found in 38 children. Intervention: Thirty-six children were treated by minimal invasive plate osteosynthesis (MIPO), and elastic stable intramedullary nail fixation (ESIN) was used in 51 children. Main Outcome Measurements: The degree of overgrowth after internal fixation compared to fracture type, fracture site, and surgical method. Multivariable logistic regression analysis was conducted to identify factors related with overgrowth. Results: The average overgrowth of the femur was 10.5 +/- 7.3 mm. There was no patient who required correction for final leg length discrepancy (>2 cm). There was no significant difference in overgrowth between ESIN (9.9 +/- 7.2 mm) and MIPO (11.2 +/- 7.6 mm) (P = 0.417). Overgrowth was similar among length-unstable fractures (12.3 +/- 7.4 mm) and length-stable fractures (9.2 +/- 7.0 mm), although it was statistically greater in length-unstable fractures (P = 0.048). In the MIPO group, length-unstable fractures were associated with an increased log odds of 6.873 for overgrowth of the femur (P = 0.042). Conclusions: Femur overgrowth after internal fixation seems to not be a clinically significant problem, regardless of whether that be for length-stable or length-unstable fractures and whether they were treated by MIPO or ESIN. Length-unstable fracture may be a risk factor for overgrowth in children. However, the difference is very small, and the postoperative overgrowth would likely not be a significant factor in deciding the surgical plan. | Park, Kyeong-Hyeon; Park, Byoung Kyu; Oh, Chang-Wug; Kim, Dae-Wook; Park, Hoon; Park, Kun-Bo | Kyungpook Natl Univ, Dept Orthoped Surg, Kyungpook Natl Univ Hosp, Sch Med, Daegu, South Korea; Inje Univ, Haeundae Paik Hosp, Dept Orthopaed Surg, Busan, South Korea; Yonsei Univ, Coll Med, Div Orthopaed Surg, Gangnam Severance Hosp, Seoul, South Korea; Yonsei Univ, Coll Med, Div Orthopaed Surg, Severance Childrens Hosp, Seoul, South Korea | KIM, DAE-WOOK/JFX-7131-2023; Park, KyeongHyeon/KEH-4919-2024; Park, Kun-Bo/IWU-4022-2023; PARK, HOON/O-8387-2018; Oh, Chang-Wug/AAO-4602-2021 | 56969984400; 56606567900; 22135834200; 59783292600; 37036320900; 16305006700 | pedoskbp@yuhs.ac; | JOURNAL OF ORTHOPAEDIC TRAUMA | J ORTHOP TRAUMA | 0890-5339 | 1531-2291 | 34 | 3 | SCIE | ORTHOPEDICS;SPORT SCIENCES | 2020 | 2.512 | 47.0 | 1.77 | 2025-06-25 | 15 | 18 | overgrowth; femur; fracture; children; internal fixation | TITANIUM ELASTIC NAILS; PLATE FIXATION; RISK-FACTORS; BONE; GROWTH | children; femur; fracture; internal fixation; overgrowth | Child; Femoral Fractures; Femur; Fracture Fixation, Internal; Fracture Fixation, Intramedullary; Fracture Healing; Humans; Retrospective Studies; Treatment Outcome; adverse event; child; clinical trial; diagnostic imaging; femur; femur fracture; fracture healing; human; intramedullary nailing; multicenter study; osteosynthesis; retrospective study; treatment outcome | English | 2020 | 2020-03 | 10.1097/bot.0000000000001652 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Photoluminescence features of reddish-orange emitting Sm³⁺doped Na3YSi2O7 phosphors | In this work, we have investigated the effect of Sm3+ concentration, mainly on the luminescent features of Na3YSi2O7:Sm3+ phosphors for white-light-emitting diode (WLED) applications. A series of Na3Y1-xSi2O7 :xSm(3+) (where x = (0.005, 0.015, 0.03, 0.05, 0.07, 0.09) mol) phosphors were synthesized using a sol-gel technique, followed by detailed characterization with various techniques, such as X-ray diffraction, diffuse reflectance spectroscopy, and photoluminescence spectroscopy. Additionally, the color purity of the phosphors was examined via CIE color coordinates. Following the diffuse reflectance spectrum, the optical band gap was evaluated for Na3Y0.985Si2O7:0.015Sm phosphor. The results showed that the Na3YSi2O7:Sm3+ phosphors could be efficiently excited by 403 nm NUV light, producing reddish-orange emission. Here, luminescence concentration quenching was identified beyond 0.015 mol Sm3+ ion doping content. The chromaticity coordinates of Na3Y0.0985Si2O7 :0.015Sm were calculated to be (0.58, 0.41), which fall in the reddish-orange region. The present study suggests that Na3YSi2O7:Sm3+ phosphors could be a potential candidate for WLED applications. | Singh, Vijay; Lakshminarayana, G.; Wagh, Akshatha; Hakeem, D.

CIE color chromaticity coordinates (x, y) for both CaLa4Si3O13:0.005 and 0.09 Sm3+ phosphors are computed following their corre-sponding emission spectra. Under 365 nm UV lamp, CaLa4Si3O13:0.09 Sm3+ sample exhibits a bright orange color emission. In this work, it was found that the CaLa4Si3O13:0.09 Sm3+ phos-phor possesses potentiality for YAG:Ce3+ phosphor color rendering index (CRI) improvement in WLEDs, excited by the blue LED chips. | Singh, Vijay; Lakshminarayana, G.; Singh, N. | Konkuk Univ, Dept Chem Engn, Seoul 05029, South Korea; Kyungpook Natl Univ, Intelligent Construct Automat Ctr, 80 Daehak Ro, Daegu 41566, South Korea | ; Gandham, Lakshminarayana/AAU-6162-2020 | 57205227140; 57194637883; 57202910594 | vijayjiin2006@yahoo.com; | OPTIK | OPTIK | 0030-4026 | 1618-1336 | 211 | SCIE | OPTICS | 2020 | 2.443 | 47.0 | 0.32 | 2025-06-25 | 5 | 6 | Sol-gel; Sm3+ ion; CaLa4Si3O13; XRD; Photoluminescence; CIE | PHOTOLUMINESCENCE CHARACTERISTICS | CaLa<sub>4</sub>Si<sub>3</sub>O<sub>13</sub> ; CIE; Photoluminescence; Sm<sup>3+</sup> ion; Sol-gel; XRD | Citrus fruits; Color; Crystal structure; Emission spectroscopy; Energy gap; Lanthanum alloys; Light emitting diodes; Luminescence; Phosphors; Photoluminescence; Samarium alloys; Silicon; Silicon alloys; Sol-gel process; X ray diffraction; Yttrium aluminum garnet; CaLa4Si3O13; Color chromaticity; Color rendering index; Diffuse reflectance spectrum; Emission spectrums; Luminescence studies; Orange color emission; XRD crystal structure; Calcium alloys | English | 2020 | 2020-06 | 10.1016/j.ijleo.2020.164272 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Influence of E-beam irradiation on microbiological and physicochemical properties and fatty acid profile of frozen duck meat | This study investigated the effect of different doses (0, 3, and 7 kGy) of e-beam on the microbiological and physicochemical qualities and the profile of fatty acids of the frozen duck meat (FDM). Electron beam at the dose of 3 kGy showed more than 2 log and 1 log cycles of reduction in the total bacterial (TAB) and coliform counts (TCC), respectively. The results indicated an increase in the TBARS values (1.50 +/- 0.02 mg MDA/kg), peroxide value (0.83 +/- 0.04 meq peroxide/kg), and total volatile base nitrogen (1.31 +/- 0.16 mg/100 ml), but no effect on the sensory parameters. Irradiation lowered the lightness (L*) (31.87 +/- 0.98) and redness (a*) (11.04 +/- 0.20) values but elevated the metmyoglobin content in FDM. In addition, irradiation had no effect on the benzopyrene content; however, a reduction was observed in the vitamin A (0.239 +/- 0.015 mu g/g) and vitamin E (1.847 +/- 0.075 mu g/g) contents of the FDM samples. There were no trans-fatty acids present in the treated (irradiated) as well as the untreated (nonirradiated) meat samples (FDM), whereas the fatty acid content decreased in irradiated samples, in contrast with the nonirradiated control. Electronic nose clearly discriminated between the nonirradiated and irradiated FDM based on principal component analysis. It is concluded that the e-beam successfully improved the microbial quality of FDM with slight changes in physicochemical properties, but without altering its sensory properties. | Arshad, Muhammad Sajid; Kwon, Joong-Ho; Ahmad, Rabia Shabir; Ameer, Kashif; Ahmad, Sheraz; Jo, Yunhee | Govt Coll Univ, Inst Home & Food Sci, Faisalabad 36000, Pakistan; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu, South Korea; PMAS Arid Agr Univ, Inst Food & Nutr Sci, Rawalpindi, Pakistan; Cholistan Univ Vet & Anim Sci, Fac Biosci, Dept Food Sci, Bahawalpur, Pakistan | Ameer, Kashif/H-5449-2019; Arshad, Muhammad/AAR-4975-2020; Ahmad, Rabia/AAW-9737-2021 | 57203062184; 36814712700; 36160301300; 57190066397; 59038336000; 56533194300 | sajid_ft@yahoo.com; | FOOD SCIENCE & NUTRITION | FOOD SCI NUTR | 2048-7177 | 8 | 2 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2020 | 2.863 | 47.2 | 1.93 | 2025-06-25 | 35 | 45 | E-nose; fatty acid; frozen duck meat; ionization radiation; microbiology; sensory evaluation | ESCHERICHIA-COLI O157H7; GAMMA-IRRADIATION; ELECTRON-BEAM; SHELF-LIFE; QUALITY CHARACTERISTICS; SENSORY CHARACTERISTICS; GROWTH-PERFORMANCE; FOOD IRRADIATION; LIPID OXIDATION; HIGH-PRESSURE | E-nose; fatty acid; frozen duck meat; ionization radiation; microbiology; sensory evaluation | English | 2020 | 2020-02 | 10.1002/fsn3.1386 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Protective effects of fermented rice extract on ulcerative colitis induced by dextran sodium sulfate in mice | Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD), characterized by the gut mucosal ulceration. Growing evidence indicates that dysregulation of immune response to the commensal microbiota involves the pathogenesis of IBD. Previous studies have demonstrated the favorable probiotic effects of fermented rice extracts through triple fermentation with Saccharomyces cerevisiae and Weissella cibaria (FRe). Thus, the therapeutic potential of FRe for UC was examined. Dextran sodium sulfate UC mice model was orally administered distilled water as a control, sulfasalazine, or FRe at 300, 200, and 100 mg/kg, once a day for a week. The UC control exhibited body weight loss, bloody stools, and colonic shortening. However, the FRe, especially at 300 mg/kg, led to a reduction in weight loss, disease activity index scores, and colon weight, and an increase in colorectal length. The histopathological analyses revealed mild changes involved in the colonic crypt and mucosal damages in the FRe groups, along with inhibited inflammation. Indeed, the FRe reduced neutrophil infiltration and production of proinflammatory cytokines (i.e., tumor necrosis factor-alpha, interleukin-6/-8). This was accompanied by the down-regulation of nuclear factor-kappa B. The gene expression responsible for the intestinal barrier integrity (i.e., Zonna occludens-1/-2, Claudin-1, Occludin, Mucin-1/-2) was up-regulated in the FRe groups. In addition, the FRe reduced lipid peroxidation and enhanced antioxidant activity. Interestingly, the microbiota dysbiosis was attenuated in the FRe groups, and the number of beneficial bacteria, Lactobacilli and Bifidobacteria, was increased. It suggests that the FRe potently ameliorate UC as a functional food. | Oh, Won-Seok; Jung, Jae-Chul; Choi, Yong-Min; Mun, Ju-Young; Ku, Sae-Kwang; Song, Chang-Hyun | Kyungpook Natl Univ, Coll Vet Med, Dept Vet Internal Med, Daegu, South Korea; NOVAREX CO Ltd, Kite Sci Res Inst, Cheongju, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Anat & Histol, Gyongsan, South Korea; Res Ctr Herbal Convergence Liver Dis, Gyongsan, South Korea | 35208796100; 7402897187; 57214132019; 57214897938; 7006331005; 24403187800 | gucci200@hanmail.net;dvmsong@hotmail.com; | FOOD SCIENCE & NUTRITION | FOOD SCI NUTR | 2048-7177 | 8 | 3 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2020 | 2.863 | 47.2 | 0.97 | 2025-06-25 | 13 | 16 | anti-inflammation; antioxidant; inflammatory bowel disease; intestinal barrier; microbiota | INFLAMMATORY-BOWEL-DISEASE; FACTOR-KAPPA-B; CROHNS-DISEASE; GUT MICROBIOTA; ACTIVATION; PATHOGENESIS; PREBIOTICS; THICKNESS; CELLS; FRE | anti-inflammation; antioxidant; inflammatory bowel disease; intestinal barrier; microbiota | English | 2020 | 2020-03 | 10.1002/fsn3.1460 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Safety assessment of Streptococcus thermophilus IDCC 2201 used for product manufacturing in Korea | Safety evaluation of probiotics has become increasingly important for human consumption in food industry. The aims of this study were to assess safety of Streptococcus thermophilus IDCC 2201 through in vitro and in vivo tests. In results, this strain was found to be negative for hemolytic and beta-glucuronidase activity. In addition,thermophilusIDCC 2201 was susceptible to nine antibiotics suggested by EFSA. In accordance with MIC tests, whole-genome analysis indicated thatS. thermophilusIDCC 2201 neither harbors antibiotic resistance nor toxigenic genes. Furthermore, none of the biogenic amines including tyramine and histamine was produced and negligible amounts of D-lactate were produced byS. thermophilusIDCC 2201. Finally, it was confirmed that there was no mortality and toxicity throughout single-dose oral toxicity tests in rats. Therefore, we report thatS. thermophilusIDCC 2201 is considered to be safe for human consumption as probiotics. | Ban, O-Hyun; Oh, Sangki; Park, Chanmi; Bang, Won Yeong; Lee, Bo Som; Yang, Soo-Yeon; Chae, Seung A.; Jung, Young Hoon; Yang, Jungwoo | Ildong BioSci, Pyeongtaek Si, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu, South Korea; Kyungpook Natl Univ, Inst Fermentat Biotechnol, Daegu, South Korea | ; Jung, Young Hoon/F-1703-2013 | 57219226382; 57219220951; 57219229140; 57208701768; 57219227122; 57219223890; 57219223373; 55550063700; 56076383700 | younghoonjung@knu.ac.kr;yjw@ildong.com; | FOOD SCIENCE & NUTRITION | FOOD SCI NUTR | 2048-7177 | 8 | 11 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2020 | 2.863 | 47.2 | 0.72 | 2025-06-25 | 16 | 16 | Antibiotic resistance; Probiotics; Safety evaluation; Single-dose oral toxicity; Streptococcus thermophilus | BIOGENIC-AMINES; PROBIOTICS; STRAINS; FOOD | Antibiotic resistance; Probiotics; Safety evaluation; Single-dose oral toxicity; Streptococcus thermophilus | English | 2020 | 2020-11 | 10.1002/fsn3.1925 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
