| ○ | Article | Evaluation of antimicrobial activity of chlorhexidine-containing oral gels against aspiration pneumonia-inducing bacteria: An in Vitro study | Aim: Hospitalised patients have a high risk of developing aspiration pneumonia because of poor oral care and oral microbial flora changes. Chlorhexidine (CHX) solution has been used to reduce inflammation and prevent infections in oral cavity, but it is difficult to use in inpatients. Gel-type antimicrobial agents rather than the liquid form may be effective for the oral management of hospitalised patients. Therefore, we evaluated the in vitro antimicrobial effects of CHX-containing oral gels on aspiration pneumonia-inducing bacteria compared to the CHX solution. Materials and Methods: The experimental products of two oral gel types containing 1% and 0.1% CHX, respectively, were selected. Hexamedine, a 0.12% CHX solution, was used as a positive control. The antimicrobial activity of CHX agents against six pneumonia-causing bacteria and Streptococcus mutans, one of the most common oral bacteria, was comparatively analysed using the agar disk diffusion method. Results: In the disk diffusion assay, the 1% CHX gels showed the highest inhibitory effect on all bacteria. All CHX agents including gels and solution had the highest antibacterial activity against Staphylococcus aureus compared with other bacteria. Conclusions: We confirmed the significant antimicrobial effects of the 1% CHX oral gels on aspiration pneumonia-inducing bacteria. These results suggest that CHX gels may be an effective oral care method for preventing infection in inpatients who have difficulty using the solution. © 2022 Wolters Kluwer Medknow Publications.

| ○ | ○ | Proceedings Paper | Evaluation of Damage Level for Ground Settlement Using the Convolutional Neural Network | In this study, a convolutional neural network (CNN)-based deep learning was applied to evaluate settlement of the ground. Firstly, the database of 1200 images was captured and labeled for three classes of damage levels. Seven CNN architectures were then selected for the transfer learning, in which the highest accuracy of approximately 96.11% for the testing set was observed from the DenseNet121 architecture. Herein, a comparison in terms of accuracy with various optimizers-algorithms for optimizing the loss function in machine learning-have been implemented in the DenseNet121 architecture. The goal of this study is to propose a better architecture with higher accuracy for practical applications in geotechnical engineering using the CNN technique. The results indicated that the DenseNet121 architecture using the Adam optimizer performed the most effectively with accuracies of 97.59%, 95.00%, and 96.11% on training, validation, and testing sets, respectively. | Park, Sung-Sik; Van-Than Tran; Nhat-Phi Doan; Hwang, Keum-Bee | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | DOAN, NHAT-PHI/IAM-1883-2023; Doan, Nhat-Phi/IAM-1883-2023 | 36241850300; 57226524301; 58095587400; 57347017900 | sungpark@knu.ac.kr;tranvanthan108@gmail.com; | CIGOS 2021, EMERGING TECHNOLOGIES AND APPLICATIONS FOR GREEN INFRASTRUCTURE | 2366-2557 | 2366-2565 | 203 | 7.46 | 2025-06-25 | 4 | 10 | Convolutional neural network (CNN); Damage classification; Deep learning; Ground settlement | Convolutional neural network (CNN); Damage classification; Deep learning; Ground settlement | Convolution; Convolutional neural networks; Deep learning; Geotechnical engineering; Network architecture; Convolutional neural network; Damage classification; Damage level; Deep learning; Ground settlement; High-accuracy; Network-based; Optimizers; Testing sets; Settlement of structures | English | 2022 | 2022 | 10.1007/978-981-16-7160-9_128 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Evaluation of the characteristics of multiple human papillomavirus (HPV) infections identified using the BD Onclarity HPV assay and comparison with those of single HPV infection | Background: Human papillomavirus (HPV) infection is a major cause of cervical cancer and associated precursor lesions. Multiple HPV genotype infections have been reported. However, their clinicopathological characteristics still remain elusive. Methods: For this study, 814 consecutive patients who had undergone colposcopy and HPV genotyping test using BD Onclarity HPV assay were retrospec-tively selected. Clinicopathological parameters of multiple HPV infections were compared with those of single HPV infection. Results: Multiple HPV infections were found in 110 out of 814 cases (13.5%). Multiple HPV infections were associated with a significantly higher incidence of high-grade intraepithelial lesions (HSILs) compared with single HPV infection. Other high-risk HPV genotypes, in addition to HPV 16, were found more frequently in the multiple HPV infections group; these included HPV 51, 52, 33/58, 56/59/66, and 35/39/68. No specific coinfection pattern was not identified. Additionally, the number of HPV genotypes in multiple HPV infections was not associated with the progression to HSIL or squamous cell carcinoma. Conclusions: Multiple HPV infections have distinct clini-copathological characteristics (compared with single HPV infection). As their biological behavior is uncertain, close and frequent fol-low-up is warranted. | Kim, Jinhee; Kim, Moonsik; Park, Ji Young | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, 807 Hoguk Ro, Daegu 41404, South Korea | Kim, Ju-Hyoung/N-1450-2019 | 57789253600; 57195918515; 57210160197 | jyparkmd@knu.ac.kr; | JOURNAL OF PATHOLOGY AND TRANSLATIONAL MEDICINE | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 56 | 5 | ESCI | PATHOLOGY | 2022 | 2.4 | 1.62 | 2025-06-25 | 9 | 10 | Human papillomavirus; Multiple HPV infection; Cervical intraepithelial neoplasia; Squamous cell carcinoma | CERVICAL-CANCER; RISK; LESIONS; CLASSIFICATION; IMPACT; WOMEN | Cervical intraepithelial neoplasia; Human papillomavirus; Multiple HPV infection; Squamous cell carcinoma | adult; Article; controlled study; female; genotyping; human; Human papillomavirus type 33; Human papillomavirus type 35; Human papillomavirus type 51; Human papillomavirus type 52; Human papillomavirus type 56; Human papillomavirus type 58; Human papillomavirus type 59; human tissue; major clinical study; middle aged; nonhuman; papillomavirus infection; retrospective study; uterine cervix carcinoma; uterine cervix carcinoma in situ | English | 2022 | 2022-09 | 10.4132/jptm.2022.08.02 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of the Public Health Emergency Response to the COVID-19 Pandemic in Daegu, Korea During the First Half of 2020 | Objectives: This study evaluated the response in Daegu, Korea to the first wave of the coronavirus disease 2019 (COVID-19) pandemic according to a public health emergency response model. Methods: After an examination of the official data reported by the city of Daegu and the Korea Centers for Disease Control and Pre - vention, as well as a literature review and advisory meetings, we chose a response model. Daegu's responses were organized into 4 phases and evaluated by applying the response model. Results: In phase 1, efforts were made to block further transmission of the virus through preemptive testing of a religious group. In phase 2, efforts were concentrated on responding to mass infections in high -risk facilities. Phase 3 involved a transition from a highintensity social distancing campaign to a citizen participation-based quarantine system. The evaluation using the response model re - vealed insufficient systematic preparation for a medical surge. In addition, an incorporated health -related management system and protection measures for responders were absent. Nevertheless, the city encouraged the participation of private hospitals and devel - oped a severity classification system. Citizens also played active roles in the pandemic response by practicing social distancing. Conclusions: This study employed the response model to evaluate the early response in Daegu to the COVID-19 pandemic and re - vealed areas in need of improvement or maintenance. Based on the study results, creation of a systematic model is necessary to pre - pare for and respond to future public health emergencies like the COVID-19 pandemic. | Lee, Hwajin; Kim, Keon-Yeop; Kim, Jong-Yeon; Kam, Sin; Lee, Kyeong Soo; Lee, Jung Jeung; Hong, Nam Soo; Hwang, Tae-Yoon | Kyungpook Natl Univ, Dept Prevent Med, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Publ Hlth, Daegu, South Korea; Yeungnam Univ, Dept Prevent Med & Publ Hlth, Coll Med, Daegu, South Korea; Keimyung Univ, Dept Prevent Med, Coll Med, Daegu, South Korea | ; Lee, Hwajin/LLK-7577-2024 | 57224495869; 35076059600; 58382951500; 55764926800; 36129485900; 57203144778; 54684167600; 13403059400 | pmkky@knu.ac.kr; | JOURNAL OF PREVENTIVE MEDICINE & PUBLIC HEALTH | 1975-8375 | 2233-4521 | 55 | 4 | 0.38 | 2025-06-25 | 3 | 3 | Public health; Emergencies; COVID-19; Republic of Korea | COVID-19; Emergencies; Public health; Republic of Korea | COVID-19; Humans; Pandemics; Public Health; Quarantine; Republic of Korea; Article; coronavirus disease 2019; death; disease classification; disease severity; emergency care; evaluation study; health care management; health care policy; high risk population; human; pandemic; private hospital; protection; public health campaign; public health service; quarantine; religious group; rescue personnel; social distancing; social participation; South Korea; virus transmission; epidemiology; pandemic; public health; South Korea | English | 2022 | 2022-07 | 10.3961/jpmph.22.068 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Conference paper | Event-Triggered Controller for Synchronization of Chaotic Neural Networks using Clock-Dependent Lyapunov Functionals | In this paper, the event-triggered controller design method for the synchronization of chaotic neural networks (CNNs) is proposed by using clock-dependent Lyapunov functionals (CLF). The aim of this study is to propose the criterion for the event-triggered controller design which synchronizes two identical CNNs by using the sum of squares (SOS) programs. The synchronization criterion based on the event-triggered mechanism (ETM) is derived by using CLF which is a polynomial with respect to the piecewise-continuous delay defined as a clock. The derived condition is formulated as the SOS programs to obtain feasible solutions. The effectiveness of the proposed method is verified via the numerical simulation of the CNN. © 2022 ACA. | Han, Seungyong; Lee, Sangmoon; Park, Ju H. | Kyungpook National University (KNU), School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University (KNU), School of Electronic and Electrical Engineering, Daegu, South Korea; Yeungnam University (YU), Department of Electrical Engineering, Gyeongsan, South Korea | 57200991395; 59510733500; 15036553900 | seungyong@knu.ac.kr; | ASCC 2022 - 2022 13th Asian Control Conference, Proceedings | 0 | 2025-06-25 | 0 | chaotic neural networks; clock-dependent Lyapunov functionals; Event-triggered controller; sum of squares; synchronization | Clocks; Controllers; Neural networks; Numerical methods; Systems engineering; Chaotic neural network; Clock-dependent lyapunov functionals; Controller design method; Controller designs; Event-triggered; Event-triggered controller; Lyapunov functionals; Piecewise-continuous; Sum of square program; Sums of squares; Synchronization | English | Final | 2022 | 10.23919/ascc56756.2022.9828237 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Book chapter | Evidence of Navigation-Guided/ Robot-Assisted Spinal Surgery | In spine surgery, minimally invasive surgery using navigation, robotics, augmented and virtual reality is progressing very rapidly. This not only makes it less invasive but also helps in the feasibility, accuracy, and efficiency of surgery. The robotic system mainly used in spine surgery is robotic-assisted navigation and virtual augmented reality system. The field of robot-assisted spine surgery still has weak indications limited to pedicle screw placement. Most studies so far have compared robot-assisted pedicle screw placement using freehand or fluoroscopy. Robot-assisted spinal surgery should show a clear improvement in results for clinical effects. Further, there remains a lack of studies on the cost-effectiveness of these procedures. Nevertheless, the next generation of innovative navigation and robotic systems will have the potential to improve spine surgery. © Springer Nature Singapore Pte Ltd. 2022. | Lee, Young-Seok; Kim, Kyoung-Tae | Department of Neurosurgery, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Neurosurgery, College of Medicine, Chung-ang University Hospital, Seoul, South Korea; Department of Neurosurgery, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Neurosurgery, Kyungpook National University Hospital, Daegu, South Korea | 57203798682; 57201369790 | nskimkt7@gmail.com; | Technical Advances in Minimally Invasive Spine Surgery: Navigation, Robotics, Endoscopy, Augmented and Virtual Reality | 0 | 2025-06-25 | 0 | Augmented virtual reality; Minimally invasive; Navigation; Robotics; Spine | English | Final | 2022 | 10.1007/978-981-19-0175-1_25 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | ○ | Article | Exogenous Fungal Endophthalmitis by Exophiala xenobiotica Infection after Cataract Surgery | Purpose: To report a case of fungal endophthalmitis secondary to Exophiala xenobiotica after cataract surgery. Case summary: A 79-year-old male presented with decreased visual acuity in the left eye 8 months after cataract surgery. He was diagnosed with uveitis and received subtenon triamcinolone injection, which has a temporary effect. Three months after the injection, his visual acuity had decreased, such that best-corrected visual acuity (BCVA) of the left eye was hand motion. Anterior chamber cells with hypopyon and severe vitritis with vitreous haze were observed in the left eye. We considered the possibility of endophthalmitis after cataract surgery, and repetitive anterior chamber irrigation with culture was conducted to identify pathogens. Systemic and intravitreal antifungal agents were injected after the isolation of Exophiala xenobiotica. However, there was no improvement of the endophthalmitis, and he underwent pars plana vitrectomy. Although inflammatory symptoms dis-appeared after surgery, black lesions in the corneal incision site were identified 3 months postoperatively. Ultimately, surgical debridement and anterior chamber injections of antifungal agents were performed for recurring endophthalmitis. After the sur-gery, there was no inflammation of the anterior chamber or vitreous cavity. The BCVA of the left eye improved to 0.5. Conclusions: Ophthalmologists should consider the possibility of fungal endophthalmitis in patients who suffer from uveitis-like symptoms after cataract surgery. | Kim, Jin Young; Park, Han Sang; Kang, Yong Koo | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea | KANG, YONG KOO/IVH-8723-2023 | 57198434314; 57208186456; 57204703736 | kykyuri@gmail.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 63 | 2 | ESCI | OPHTHALMOLOGY | 2022 | 0.1 | 0.21 | 2025-06-25 | 1 | 1 | Exophiala xenobiotica; Fungal endophthalmitis; Pars plana vitrectomy | EXPERIENCE | Exophiala xenobiotica; Fungal endophthalmitis; Pars plana vitrectomy | Korean | 2022 | 2022-02 | 10.3341/jkos.2022.63.2.206 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Exogenous Phytohormones and Fertilizers Enhance Jatropha curcas L. Growth through the Regulation of Physiological, Morphological, and Biochemical Parameters | Jatropha curcas L. is a perennial plant, that emerged as a biodiesel crop attracting the great interest of researchers. However, it is considered a semi-wild plant and needed to apply crop-improving practices to enhance its full yield potential. This study was conducted to improve the growth and development of the J. curcas plant by exogenous application of Gibberellic acid (GA), indole acetic acid (IAA), and fertilizer (nitrogen, phosphorus, potassium (NPK)). The experiment was conducted in pots in triplicate and 100 ppm and 250 ppm of GA and IAA were applied separately while NPK was applied in two levels (30 and 60 g/pot). The results revealed a significant difference in growth parameters with the application of hormones and fertilizer. The highest shoot length (47%), root length (63%), root fresh weight (72%), and root dry weight (172%) were shown by plants treated with GA 250 ppm. While plants treated with NPK 60 g showed the highest increases in shoot fresh weight and shoot dry weight compared to control plants. The highest increase in leaves number (274%) and branches number (266%) were shown by the plants treated with GA 100 ppm and GA 250 ppm, respectively, while GA 250 ppm and IAA 250 ppm highly increased stem diameter (123%) and stem diameter was also shown by GA 250 ppm-treated plants. NPK 60 g highly increased proximate composition (protein content, carbohydrate, fat, moisture content, and ash content) compare with hormones and control plants. Our results concluded the optimized concentration of IAA, GA, and NPK significantly increases J. curcas growth vigor. | Jan, Rahmatullah; Khan, Murtaza; Adnan, Muhammad; Asaf, Sajjad; Asif, Saleem; Kim, Kyung-Min; Murad, Waheed | Kyungpook Natl Univ, Grad Sch, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Coastal Agr Res Inst, Daegu 41566, South Korea; Yeungnam Univ, Dept Hort & Life Sci, Gyongsan 38541, South Korea; Kohat Univ Sci & Technol, Dept Bot & Environm Sci, Kohat 26000, Pakistan; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 616, Oman; Abdul Wali Khan Univ, Dept Bot, Mardan 23200, Pakistan | Kim, Kyung-Min Kim/C-7007-2014; Asaf, Sajjad/ABA-3647-2021; Murad, Waheed/HGE-7090-2022; Adnan, Muhammad/AGI-4537-2022; Jan, Rahmatullah/AIC-3439-2022 | 57201981969; 57207990116; 57214352598; 56595059900; 57396413700; 34868260300; 55394220500 | kkm@knu.ac.kr;waheedmurad@awkum.edu.pk; | PLANTS-BASEL | 2223-7747 | 11 | 24 | 1.59 | 2025-06-25 | 11 | 14 | biodiesel; gibberellin; growth parameters; indole acetic acid; Jatropha curcas; proximate composition | GIBBERELLIC-ACID; CARBONIC-ANHYDRASE; USE EFFICIENCY; AUXIN; DIFFERENTIATION; PHOTOSYNTHESIS; EXPRESSION; MUTANT; YIELD; WATER | biodiesel; gibberellin; growth parameters; indole acetic acid; Jatropha curcas; proximate composition | English | 2022 | 2022-12 | 10.3390/plants11243584 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Expert Consensus on Measures to Promote Physical and Psychological Health among COVID-19-Related Healthcare Workers in Korea using Delphi Technique | Background: The coronavirus disease 2019 (COVID-19) pandemic has caused health problems and distress among healthcare workers (HCWs), so supportive measures to promote their health and relieve distress are needed. Materials and Methods: We conducted two rounds of Delphi surveys with 20 COVID-19-related frontline healthcare professionals and public officials. The surveys evaluated means of supporting HCWs' health by improving health care systems and working environments in terms of effectiveness and urgency. The validity of the measures was assessed by calculating the content validity ratio. Results: The top-priority measures to support HCWs were "secure isolation units capable of treating severe cases" in the facility infrastructure category, "secure nursing staff dedicated for patients in the intensive care units" in the personnel infrastructure category, "improve communication between central office and frontline field" in the cooperation system category, "support personal protective equipment and infection control supplies" in the aid supplies category, and "realization of hazard pay" in the physical/mental health and compensation category. Conclusion: There was consensus among the experts on the validity and priorities of policies in the facility, personnel, cooperation, supplies, and compensation categories regarding measures to promote COVID-19 related HCWs' health. | Lee, So Hee; Noh, Jin-Won; Kim, Yeonjae; Ryoo, Hyun Wook; Park, Kyung-Hwa; Park, Se Yoon; Lee, Shinwon; Cheong, Hae Suk; Heo, Sang Taek; Hong, Ki Jeong; Kim, Kyoung-Beom; Kwon, Ki Tae | Natl Med Ctr, Dept Psychiat, Seoul, South Korea; Yonsei Univ, Div Hlth Adm, Coll Software & Digital Healthcare Convergence, Wonju, South Korea; Natl Med Ctr, Div Infect Dis, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Emergency Med, Daegu, South Korea; Chonnam Natl Univ, Chonnam Natl Univ Hosp, Dept Infect Dis, Sch Med, Gwangju, South Korea; Yonsei Univ, Yongin Severance Hosp, Dept Hosp Med, Coll Med, Yongin, South Korea; Yonsei Univ Hlth Syst, Yongin Severance Hosp, Ctr Digital Hlth, Yongin, South Korea; Pusan Natl Univ, Dept Internal Med, Sch Med, Busan, South Korea; Pusan Natl Univ, Med Res Inst, Busan, South Korea; Sungkyunkwan Univ, Kangbuk Samsung Hosp, Sch Med, Div Infect Dis,Dept Internal Med, Seoul, South Korea; Jeju Natl Univ, Coll Med, Div Infect Dis, Dept Internal Med, Jeju, South Korea; Seoul Natl Univ, Coll Med & Hosp, Lab Emergency Med Serv, Seoul Natl Univ Hosp Biomed Res Inst,Dept Emergen, Seoul, South Korea; Dankook Univ, Dept Hlth Adm, Cheonan, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Div Infect Dis,Dept Internal Med, Daegu, South Korea | ; Kim, Hanjin/KYP-2633-2024; Lee, Eun/J-2780-2012; Kim, Sunuk/KJM-5211-2024; Hong, Ki Jeong/ISV-4044-2023; Lee, So Hee/B-5940-2016 | 56442744300; 54384018600; 56066688300; 55350557500; 57219637574; 55259986400; 24479446100; 57233155100; 9737963500; 55433745900; 57193254193; 9733850500 | jinwon.noh@gmail.com;ktkwon@knu.ac.kr; | INFECTION AND CHEMOTHERAPY | INFECT CHEMOTHER | 2093-2340 | 2092-6448 | 54 | 2 | ESCI | INFECTIOUS DISEASES | 2022 | 4.2 | 0.8 | 2025-06-25 | 5 | 6 | COVID-19; Delphi technique; Health personnel; Policy | MENTAL-HEALTH | COVID-19; Delphi technique; Health personnel; Policy | adult; Article; clinical article; consensus; content validity; controlled study; coronavirus disease 2019; Delphi study; emergency health service; emotional support; female; health care personnel; health promotion; human; infection control; intensive care unit; leisure; male; mental disease; mental health; nursing staff; physical disease; program effectiveness; psychiatric treatment; psychological counseling; South Korea; university hospital; work environment | English | 2022 | 2022-06 | 10.3947/ic.2021.0137 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Review | Expert opinion: The clinical usefulness of skin tests prior to the administration of beta-lactam antibiotics | An allergy skin test is used to diagnose certain allergies by identifying sensitized allergens. In other words, it is a test for patients who are already sensitized to certain allergens. Because of the prevailing perception that beta-lactam allergy can be dangerous and potentially lethal, the intradermal test has long been routinely performed before use to screen beta-lactam allergy in Korea. The prevalence of penicillin allergy is estimated to be 1% to 2%. However, only 14% of the subjects with perceived penicillin allergy is considered to have true penicillin allergy. Moreover, it is difficult to justify performing a skin test on subjects who are very unlikely to be sensitized to beta-lactam, such as those who never used beta-lactam or never experienced allergy after previous use of beta-lactam. Therefore, allergists recommend beta-lactam skin testing in those who have allergy after the use of beta-lactam. Nevertheless, many hospitals in Korea are conducting routine skin tests on patients regardless of a history of beta-lactam allergy, which are not clinically validated but consume considerable human and material resources. False-positive results can consequently result in inappropriate labeling of beta-lactam allergy, leading to the unnecessary restriction of medication prescriptions and the increase in medical expenses. Herein, the drug allergy working group affiliated with the Korean Academy of Asthma, Allergy, and Clinical Immunology announces an expert opinion on the preuse beta-lactam skin test for subjects without a history of beta-lactam allergy based on the objective evidence from the literature and clinical relevance. | Kim, Sung-Ryeol; Kim, Sujeong; Kim, Sae-Hoon; Park, Jong-Sook; Park, Hye Jung; Suh, Dong In; Sim, Da Woon; Yang, Min Suk; Lee, Jae-Hyun; Lee, Hwa Young; Jung, Jae-Woo; Choi, Mira; Kang, Hye-Ryun | Yonsei Univ, Yongin Severance Hosp, Coll Med, Dept Internal Med,Div Pulmonol Allergy & Crit Car, Yongin, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Seoul, South Korea; Soonchunhyang Univ, Bucheon Hosp, Dept Internal Med, Div Allergy & Resp Med, Bucheon, South Korea; Yonsei Univ, Gangnam Severance Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Pediat, Seoul, South Korea; Chonnam Natl Univ, Chonnam Natl Univ Hosp, Med Sch, Dept Allergy & Clin Immunol, Gwangju, South Korea; SMG SNU Boramae Med Ctr, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Severance Hosp, Coll Med, Dept Internal Med,Div Allergy & Immunol, Seoul, South Korea; Catholica Univ Korea, Seoul St Marys Hosp, Dept Internal Med, Coll Med,Div Allergy, Seoul, South Korea; Chung Ang Univ, Chung Ang Univ Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Inje Univ, Ilsan Paik Hosp, Coll Med, Dept Dermatol, Goyang, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Inst Allergy & Clin Immunol, Med Res Ctr, Seoul, South Korea | Jung, Jae-Woo/L-9451-2019; Lee, Jeong/JFA-4725-2023; Kim, Sung-Ryeol/L-9266-2019; Lee, Jae-Hyun/HLQ-3056-2023; Kim, Ju-Hyoung/N-1450-2019 | helenmed@snu.ac.kr; | ALLERGY ASTHMA & RESPIRATORY DISEASE | ALLERGY ASTHMA RESPI | 2288-0402 | 2288-0410 | 10 | 1 | ESCI | ALLERGY | 2022 | 0.2 | 4 | Drug hypersensitivity; Skin tests; Penicillins; Beta-lactams | PENICILLIN ALLERGY; NONIMMEDIATE REACTIONS; GOOD TOLERANCE; CHALLENGE; HYPERSENSITIVITY; DERIVATIVES; POLYLYSINE; DIAGNOSIS; OUTCOMES; HISTORY | Korean | 2022 | 2022-01 | 10.4168/aard.2022.10.1.3 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Exploiting Data Compression for Adaptive Block Placement in Hybrid Caches | STT-RAM (Spin-Transfer Torque Random Access Memory) appears to be a viable alternative to SRAM-based on-chip caches. Due to its high density and low leakage power, STT-RAM can be used to build massive capacity last-level caches (LLC). Unfortunately, STT-RAM has a much longer write latency and a much greater write energy than SRAM. Researchers developed hybrid caches made up of SRAM and STT-RAM regions to cope with these challenges. In order to store as many write-intensive blocks in the SRAM region as possible in hybrid caches, an intelligent block placement policy is essential. This paper proposes an adaptive block placement framework for hybrid caches that incorporates metadata embedding (ADAM). When a cache block is evicted from the LLC, ADAM embeds metadata (i.e., write intensity) into the block. Metadata embedded in the cache block are then extracted and used to determine the block's write intensity when it is fetched from main memory. Our research demonstrates that ADAM can enhance performance by 26% (on average) when compared to a baseline block placement scheme. | Kim, Beomjun; Kim, Yongtae; Nair, Prashant; Hong, Seokin | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Univ British Columbia, Dept Elect & Comp Engn, Vancouver, BC V6T 1Z4, Canada; Sungkyunkwan Univ, Dept Semicond Syst Engn, Suwon 16419, South Korea | Nair, Prashant/AAB-4697-2019 | 57743131700; 55699627900; 7201717281; 55597086808 | beomjun0816@knu.ac.kr;yongtae@knu.ac.kr;prashantnair@ece.ubc.ca;seokin@skku.edu; | ELECTRONICS | 2079-9292 | 11 | 2 | 0 | 2025-06-25 | 0 | 0 | last-level cache; hybrid cache; non-volatile memory; STT-RAM | PERFORMANCE; ENERGY; PREDICTION | Hybrid cache; Last-level cache; Non-volatile memory; STT-RAM | English | 2022 | 2022-01 | 10.3390/electronics11020240 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Exploratory Data Analytics of Total Population Over Fertility Rate in South Korea | The Republic of Korea is experiencing a demographic crisis with low birth rates and aging population. As the present circumstance represents a developing danger to the supportability of its economy, schooling, accounts, and protection, there is a critical requirement for definite and comprehensive activity. South Korea is one among the world's quickest maturing nations. There might be a crucial impact forecasted if the country does not mitigate this growing jeopardy on the population. In this paper, we designed a prediction model using the machine learning algorithm such as multiple linear regression on the total population and fertility rate data to do the exploratory data analysis about the future trend in the population and its impacts which would affect the wellfare of the nation. The correlation and prediction results showed an accuracy of 98%, with a declining trend of the fertility rate for the upcoming years as well. We evaluated the prediction model performance using root mean squared error and mean absolute error values in the training and testing of the model. Therefore, we concluded the paper with the future challenges for the country having such population trends. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Ganesan, Anusha; Paul, Anand | School of Computer Science and Engineering, Kyungpook National University, Buk-gu, Daegu, South Korea; School of Computer Science and Engineering, Kyungpook National University, Buk-gu, Daegu, South Korea | 57226711297; 56650522400 | paul.editor@gmail.com; | Lecture Notes in Electrical Engineering | 1876-1100 | 936 | 0 | 2025-06-25 | 0 | Fertility rate; Machine learning; Multiple linear regression; South Korea; Total population; Younger population | Data Analytics; Forecasting; Learning algorithms; Machine learning; Mean square error; Population statistics; Birth rates; Data analytics; Fertility rates; Machine-learning; Multiple linear regressions; Prediction modelling; Republic of Korea; South Korea; Total population; Young population; Multiple linear regression | English | Final | 2022 | 10.1007/978-981-19-5037-7_55 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Exploring the experiences and perspectives of emergency physicians on brain death organ tissue donation after the Life-Sustaining Treatment Decision Act | Background: This study explored emergency physicians' experiences and perspectives related to brain death organ tissue donation (OTD) after the enforcement of the Life-Sustaining Treatment (LST) Decision Act in Korea. Methods: Using the Braun and Clarke thematic analysis method, this qualitative study analyzed interview data-comprising experiences and perspectives of brain death OTD since the LST Decision Act-of 10 emergency physicians who specialized in targeted temperature management (TTM) and cared for post-cardiac arrest patients. Results: Data analysis revealed 13 subthemes and 5 themes: the LST Decision Act is easier to explain to family members than brain death OTD, but it does not fit well in an emergency medical setting; many family members decide to stop LST even before physicians mention brain death or OTD; family members view stopping LST as being about comforting patients without bothering them, and decision-makers are therefore no longer willing to choose OTD; stopping LST does not always result in brain death, but cases of brain death are preceded by stopping LST; and since the LST Decision Act, the number of TTM cases and potential brain death donors has decreased. Conclusions: Unless a supplementary policy that connects stopping LST to brain death OTD is prepared, the withdrawal of LST in patients resuscitated after cardiac arrest is expected to continue, and brain death OTD is expected to decrease. © Kazan Medical Journal.

| ○ | ○ | Article | Expression of ICAM-1 in Blood Vascular Endothelium and Tissues in Human Premalignant Lesion and Gastric/Hepatocellular Carcinomas | Background/Aims: Angiogenesis is essential for the outgrowth and metastasis of tumors. The structure and characteristics of tumor vasculature differ from those of normal vessels. We compared the characteristics of differentially expressed genes in endothelial cells (ECs) isolated from gastric and normal cells. Methods: Previously, we had isolated pure tumor ECs (TECs) and normal ECs (NECs) from advanced gastric cancer (AGC) lesions and normal mucosal tissues, respectively. Using the oligomer chip platform of the Affymetrix GeneChip technology, genes that were expressed more than three-fold with a significance of p <= 0.001 were measured. The intercellular adhesion molecule 1 (ICAM-1) was found to be overexpressed in the TECs compared to the normal gastric ECs. In this study, the upregulation of ICAM-1 was confirmed in cultured TECs by immunofluorescence. Results: The expression of ICAM-1 was upregulated in the ECs, as well as in the stromal and immune cells, in early human gastric preneoplastic and hepatic fibrotic tissues. Upregulation of ICAM-1 was observed in the TECs, immune cells, and cancer epithelial cells in AGC and hepatocellular carcinoma (HCC). These results suggest that increased ICAM-1 expression in the ECs of the tissue microenvironment progressively contributes to the recruitment of immune cells to promote inflammation, leading to fibrosis and tumorigenesis. Conclusions: Therefore, upregulated ICAM-1 in the tissues in premalignant gastric diseases or hepatic fibrosis and their malignant cancers could be a promising target for disease prevention and treatment. | Kang, Li; Kim, Moonsik; Lee, You Mie | Kyungpook Natl Univ, Dept Mol Pathophysiol, Coll Pharm, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Vessel Organ Interact Res Ctr, VOICE MRC, Daegu, South Korea | Lee, Kyung-Soo/C-9016-2011 | 57642827700; 57195918515; 8230508600 | lym@knu.ac.kr; | KOREAN JOURNAL OF GASTROENTEROLOGY | KOR J GASTROENTEROL | 1598-9992 | 2233-6869 | 79 | 4 | ESCI | GASTROENTEROLOGY & HEPATOLOGY | 2022 | 0.6 | 0.32 | 2025-06-25 | 2 | 2 | Intercellular adhesion molecule-1; Tumor endothelial cells; Premalignant lesion; Stomach neoplasm; Liver neoplasm | GASTRIC-CANCER; ANGIOGENESIS; ASSOCIATION; CELLS | Intercellular adhesion molecule-1; Liver neoplasm; Premalignant lesion; Stomach neoplasm; Tumor endothelial cells | Carcinoma, Hepatocellular; Endothelial Cells; Endothelium, Vascular; Humans; Intercellular Adhesion Molecule-1; Liver Neoplasms; Stomach Neoplasms; Tumor Microenvironment; intercellular adhesion molecule 1; endothelium cell; genetics; human; liver cell carcinoma; liver tumor; metabolism; pathology; stomach tumor; tumor microenvironment; vascular endothelium | English | 2022 | 2022-04 | 10.4166/kjg.2022.008 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Extraction of Color Information and Visualization of Color Differences between Digital Images through Pixel-by-Pixel Color-Difference Mapping | A novel method of extracting color information on a pixel-by-pixel basis or by the average of the regions of interest (ROIs) from digital images is proposed and demonstrated using newly developed and customized image-processing/analysis software (PicMan). For quantitative and statistical analyses of color, the newly developed software can be used for digital archive or digital forensic applications in various fields. The color differences between unrelated, similar, or identical scenes and or objects were quantified in various formats of desired color spaces such as RGB, HSV, XYZ, CIE L*a*b*, Munsell color, and hexadecimal color values. The color differences were visualized as images of pixel-by-pixel mapping of the Delta L*, Delta a*, Delta b*, Delta E-RGB, Delta E-HSV, and Delta E*(L)*(a)*(b)* values and block comparison images of desired block sizes. Various color analyses and color-difference mapping examples using an aged and damaged oil painting before and after restoration were introduced. The effects of the image file format differences between PNG and JPG on color distortion are demonstrated by statistics and pixel-by-pixel color-difference mapping. A portrait of Chuk-ki Yoo (1691-1767) on silk from the 18th century from Korea was used for further color analysis for whole and selected areas. A collector's ownership stamp of Chuk-ki Yoo stamped in red ink on the text areas in one of his book collections was extracted using the image-processing software and superimposed on the original image as a visualization enhancement example. Image analysis, processing, modification, enhancement, and highlighting, as well as statistical color analysis of digital images in most formats, can conveniently and efficiently be performed using one piece of dedicated software (PicMan). The pixel-by-pixel color information extraction and color comparison technique can be very effective for a variety of applications in art and cultural heritage objects. | Yoo, Woo Sik; Kang, Kitaek; Kim, Jung Gon; Yoo, Yeongsik | WaferMasters Inc, Dublin, CA 94568 USA; Kyungpook Natl Univ, Inst Humanities Studies, Daegu 41566, South Korea; Dankook Univ, Coll Liberal Arts, Yongin 16890, South Korea | 55665974300; 9638686700; 48161606000; 57205391310 | woosik.yoo@wafermasters.com; | HERITAGE | HERITAGE-BASEL | 2571-9408 | 5 | 4 | ESCI | HUMANITIES, MULTIDISCIPLINARY;MULTIDISCIPLINARY SCIENCES | 2022 | 1.7 | 3.99 | 2025-06-25 | 12 | 14 | image analysis software; image-processing software; PicMan; image analysis; image comparison; color analysis; color difference visualization; art; cultural heritage | METAL-TYPE; KOREA; SONG | art; color analysis; color difference visualization; cultural heritage; image analysis; image analysis software; image comparison; image-processing software; PicMan | English | 2022 | 2022-12 | 10.3390/heritage5040202 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
