| ○ | ○ | Article | Effects of Changes to Architectural Elements on Human Relaxation-Arousal Responses: Based on VR and EEG | This study combines electroencephalogram (EEG) with virtual reality (VR) technologies to measure the EEG responses of users experiencing changes to architectural elements. We analyze the ratio of alpha to beta waves (RAB) indicators to determine the pre- and poststimulation changes. In our methodology, thirty-three females experience using private rooms in a postpartum care center participated in the experiment. Their brain waves are measured while they are experiencing the VR space of a private room in a postpartum care center. Three architectural elements (i.e., aspect ratio of space, ceiling height, and window ratio) are varied in the VR space. In addition, a self-report questionnaire is administered to examine whether the responses are consistent with the results of the EEG response analysis. As a result, statistically significant differences (p < 0.05) are observed in the changes in the RAB indicator values of the pre- and poststimulation EEG while the subjects are experiencing the VR space where the architectural elements are varied. That is, the effects of the changes to architectural elements on users' relaxation-arousal responses are statistically verified. Notably, in all the RAB indicator values where significant differences are observed, the poststimulation RAB decreases in comparison to the prestimulus ratios, which is indicative of the arousal response. However, the arousal levels vary across the architectural elements, which implies it would be possible to find out the elements that could induce less arousal response using the proposed method. Moreover, following the experience in the VR space, certain lobes of the brain (F4 and P3 EEG channels) show statistically significant differences in the relaxation-arousal responses. Unlike previous studies, which measured users' physiological responses to abstract and primordial spatial elements, this study extends the boundaries of the literature by applying the architectural elements applicable to design in practice. | Kim, Sanghee; Park, Hyejin; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 57222484247; 57226002455; 36835366900 | sangheekim@knu.ac.kr;phj8598@knu.ac.kr;choo@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 8 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 1.82 | 2025-07-30 | 34 | 36 | architectural elements; EEG; VR; relaxation-arousal reaction; healing space | CEREBRAL HEMISPHERES; VIRTUAL-REALITY; CEILING HEIGHT; WINDOW; SPACES; ALPHA; EMOTIONS; VIEW; FMRI | Architectural elements; EEG; Healing space; Relaxation-arousal reaction; VR | Arousal; Electroencephalography; Female; Humans; Relaxation; Surveys and Questionnaires; Virtual Reality; Indicator indicator; brain; physiological response; technology; virtual reality; adult; arousal; article; beta rhythm; clinical article; controlled study; electroencephalogram; female; human; human experiment; leisure; puerperium; questionnaire; self report; virtual reality; arousal; electroencephalography; leisure | English | 2021 | 2021-04 | 10.3390/ijerph18084305 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of the professional oral care management program on patients with head and neck cancer after radiotherapy: A 12-month follow-up | Background/purpose: Because oral health of patients with head & neck cancer is prone to disease after radiotherapy, effective and long-lasting oral care program is necessary. We aimed to evaluate the effects of the oral care management program, which lasted up to 12 months after radiotherapy for patients with head and neck cancer. Materials and methods: Sixty-eight patients who visited a dental clinic prior to the initiation of radiotherapy were recruited and categorized into either a "healthy" or a "vulnerable" group. The vulnerable group was made of patients with dental caries or periodontal attachment loss. Professional oral hygiene care, including tooth brushing instructions, professional mechanical tooth cleaning, and fluoride varnish application, was conducted once every week for a month during radiotherapy and once every 3 months after radiotherapy. Oral health, including dental caries, plaques, gingival index, and periodontal attachment loss, was examined at baseline, 6 months, and 12 months after radiotherapy. Results:; Twenty-nine and 16 patients were followed up at 6 and 12 months after radiotherapy, respectively. Oral health indices, such as the number of decayed teeth, amount of plaque, and gingival index, did not significantly change in either group. However, the periodontal pocket depth significantly decreased in both groups at 6 months after baseline, and this decrease continued in the vulnerable group up to 12 months after baseline. Conclusion: Periodic dental visits and professional oral hygiene care during and after radiotherapy were effective in maintaining oral health for over 12 months after radiotherapy in patients with head and neck cancer.

| ○ | ○ | Article | Facile Use of Silver Nanoparticles-Loaded Alumina/Silica in Nanofluid Formulations for Enhanced Catalytic Performance toward 4-Nitrophenol Reduction | The introduction of toxic chemicals into the environment can result in water pollution leading to the degradation of biodiversity as well as human health. This study presents a new approach of using metal oxides (Al2O3 and SiO2) modified with a plasmonic metal (silver, Ag) nanoparticles (NPs)-based nanofluid (NF) formulation for environmental remediation purposes. Firstly, we prepared the Al2O3 and SiO2 NFs of different concentrations (0.2 to 2.0 weight %) by ultrasonic-assisted dispersion of Al2O3 and SiO2 NPs with water as the base fluid. The thermo-physical (viscosity, activation energy, and thermal conductivity), electrical (AC conductivity and dielectric constant) and physical (ultrasonic velocity, density, refractive index) and stability characteristics were comparatively evaluated. The Al2O3 and SiO2 NPs were then catalytically activated by loading silver NPs to obtain Al2O3/SiO2@Ag composite NPs. The catalytic reduction of 4-nitrophenol (4-NP) with Al2O3/SiO2@Ag based NFs was followed. The catalytic efficiency of Al2O3@Ag NF and SiO2@Ag NF, for the 4-NP catalysis, is compared. Based on the catalytic rate constant evaluation, the catalytic reduction efficiency for 4-NP is found to be superior for 2% weight Al2O3@Ag NF (92.9 x 10(-3) s(-1)) as compared to the SiO2@Ag NF (29.3 x 10(-3) s(-1)). Importantly, the enhanced catalytic efficiency of 2% weight Al2O3@Ag NF for 4-NP removal is much higher than other metal NPs based catalysts reported in the literature, signifying the importance of NF formulation-based catalysis. | Mannu, Rashmi; Karthikeyan, Vaithinathan; Veerappa, Murugendrappa Malalkere; Roy, Vellaisamy A.

| ○ | ○ | Article | Factors Influencing Preparedness for Bioterrorism among Koreans | Bioterrorism is destructive enough to cause a societal collapse, and preparation for bioterrorism is imperative. This study aims to identify the factors influencing preparedness for bioterrorism among Koreans. A total of 1050 subjects were included in the study, which were allocated according to region and age in proportion to population. An online survey was used to examine the following factors: participants' general characteristics; cognitive factors including perceived probability, perceived seriousness, perceived personal impact, perceived coping efficacy, and perceived resilience; social-contextual factors including perceived governmental preparedness and perceived front-line preparedness; affective responses including affective response to terrorism and anxiety; and bioterrorism preparedness. The factors influencing the level of preparedness for bioterrorism included age, marital status, experience of bioterrorism education, perceived personal impact, perceived coping efficacy, perceived resilience, and perceived front-line preparedness. The factors that most significantly affected the level of preparedness for bioterrorism were perceived coping efficacy and perceived front-line preparedness, with an R-2 of 41.4%. Relevant education and public relations programs should be strengthened to help citizens minimize their exposure and known to inform relevant institutions in the event of suspected bioterrorism, and front-line responders should cultivate their ability to respond to bioterrorism quickly and accurately. | Kim, Yujeong; Lee, Eunmi | Kyungpook Natl Univ, Res Inst Nursing Sci, Coll Nursing, Daegu 41944, South Korea; Hoseo Univ, Res Inst Basic Sci, Dept Nursing, Asan 31499, South Korea | Lee, Eunmi/AAS-2561-2020 | 57200941945; 57202264064 | yujeongkim@knu.ac.kr;sweetbear2@hanmail.net; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 10 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.42 | 2025-07-30 | 6 | 6 | bioterrorism; biological warfare; emergency preparedness; coping behaviors | INDIVIDUAL-RESPONSE; MODEL | Biological warfare; Bioterrorism; Coping behaviors; Emergency preparedness | Bioterrorism; Disaster Planning; Humans; Republic of Korea; Surveys and Questionnaires; Terrorism; Korea; coping strategy; disaster management; education; perception; terrorism; war; adult; anxiety; article; bioterrorism; controlled study; coping behavior; drug efficacy; education; female; human; Korean (people); major clinical study; male; marriage; probability; public relations; bioterrorism; disaster planning; questionnaire; South Korea; terrorism | English | 2021 | 2021-05 | 10.3390/ijerph18105401 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Microbial Enzymatic Synthesis of Amikacin Analogs With Antibacterial Activity Against Multidrug-Resistant Pathogens | With the constant emergence of multidrug-resistant gram-negative bacteria, interest in the development of new aminoglycoside (AG) antibiotics for clinical use has increased. The regioselective modification of AG scaffolds could be an efficient approach for the development of new antibiotics with improved therapeutic potency. We enzymatically synthesized three amikacin analogs containing structural modifications in the amino groups and evaluated their antibacterial activity and cytotoxicity. Among them, 6 '-N-acyl-3('')-N-methylated analogs showed improved antibacterial activity against the multidrug-resistant gram-negative bacteria tested, while exhibiting reduced in vitro nephrotoxicity compared to amikacin. This study demonstrated that the modifications of the 6 '-amino group as well as the 3('')-amino group have noteworthy advantages for circumventing the AG-resistance mechanism. The regiospecific enzymatic modification could be exploited to develop novel antibacterial agents with improved pharmacological potential. | Ban, Yeon Hee; Song, Myoung Chong; Jeong, Joong Ho; Kwun, Min Seok; Kim, Chang Rae; Ryu, Hwi So; Kim, Eunji; Park, Je Won; Lee, Dong Gun; Yoon, Yeo Joon | Seoul Natl Univ, Coll Pharm, Nat Prod Res Inst, Seoul, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, Daegu, South Korea; Korea Univ, Dept Integrated Biomed & Life Sci, Seoul, South Korea | Kim, Ji-Young/HJA-5494-2022; Song, Myoung/M-7381-2013; Lee, Dong-Gun/IWD-9833-2023 | 35279095000; 9335354000; 57255120100; 57212491555; 57255120200; 57255235200; 58576417500; 8710254600; 55668060900; 7402126465 | yeojoonyoon@snu.ac.kr; | FRONTIERS IN MICROBIOLOGY | FRONT MICROBIOL | 1664-302X | 12 | SCIE | MICROBIOLOGY | 2021 | 6.064 | 24.5 | 0.43 | 2025-07-30 | 6 | 8 | amikacin analogs; microbial enzymatic synthesis; multidrug-resistant pathogens; antibacterial activity; cytotoxicity | AMINOGLYCOSIDE ANTIBIOTICS; BIOSYNTHESIS; KANAMYCIN; TOXICITY; SIDE | amikacin analogs; antibacterial activity; cytotoxicity; microbial enzymatic synthesis; multidrug-resistant pathogens | amikacin; aminoglycoside; ampicillin; antibiotic agent; bovine serum albumin; antibacterial activity; antibiotic sensitivity; Article; broth dilution; chemical structure; controlled study; cytotoxicity; enzyme synthesis; Escherichia coli; human; human cell; in vitro study; infectious agent; mass spectrometry; Micromonospora; minimum inhibitory concentration; multidrug resistance; multidrug resistant Gram negative bacterium; nephrotoxicity; nuclear magnetic resonance imaging; Pseudomonas aeruginosa; solid phase extraction; Staphylococcus aureus; ultra performance liquid chromatography | English | 2021 | 2021-08-27 | 10.3389/fmicb.2021.725916 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Miscibility analysis of polyol-ester based oil SW32 with R404A and low-GWP refrigerant R452A | Refrigerant/lubricant miscibility plays an important role in the overall thermal performance and reliability of refrigeration and air-conditioning systems. R452A is considred a viable replacement of R404A refrigerant due to its comparible thermophysical properties and low global warming potential. In this paper, the miscibility of a polyol ester based oil SW32 is experimentally investigated with R404A and R452A by varying the oil mass fraction from 5% to 70% over the temperature range of 243.15K to 313.15K. The results revealed R452A is completely miscible with SW32 oil up to 30% oil mass fraction over the whole temperature range considered in the study followed by R404A which showed complete miscibility up to 20% oil mass fraction. Liquid phase separation showed the presence of three different types of immisicibility present for both refrigerant at higher oil mass fractions. Moreover, the low-global warming potential alternative, R452A demonstrated an 18% higher miscibility region with SW32 oil compared to R404A. (c) 2021 Elsevier Ltd and IIR.

| ○ | ○ | Article | More Teeth and Posterior Balanced Occlusion Are a Key Determinant for Cognitive Function in the Elderly | Age-related decline in cognitive function is a major challenge in geriatric healthcare. A possible explanation is that the tooth loss or low chewing ability is at cause of cognitive impairment or dementia. The study aimed to investigate the potential relationship between chewing ability and cognitive function in the elderly. A total of 563 participants aged 65 years or over residing in urban and rural areas of South Korea were surveyed. The chewing ability was measured by objectively measurable indications such as the number of remaining teeth, denture status, color-changeable gum, and occlusal balance using T-Scan III(R). The cognitive function was measured by the Korean version of Mini-Mental State Examination-Dementia Screening (MMSE-DS) and a score of 24 or more (out of 30) indicates a normal cognition, below 23 indicates cognitive impairment. The association between socio-demographic factors, chewing ability factors, and cognitive function demonstrated statistically significant results. When comparing the denture status and chewing ability, the proportion of need denture group had fewer remaining teeth and anterior balanced occlusion. The average number of remaining teeth in anterior balanced occlusion with cognitive impairment was 11.2 compared to posterior balanced occlusion with the normal cognition 19.2. A multiple linear regression analysis declared a significant correlation between number of remaining teeth, denture status, occlusal balance, and cognitive function. Results of the present study revealed objectively measurable indications are suitable for chewing ability assessment and correlated with cognitive function. | Park, Taejun; Jung, Yun-Sook; Son, Keunbada; Bae, Yong-Chul; Song, Keun-Bae; Amano, Atsuo; Choi, Youn-Hee | Kyungpook Natl Univ, Sch Dent, Dept Prevent Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Coll Sci & Technol, Dept Dent Hyg, Sangju 37224, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Anat & Neurobiol, Daegu 41940, South Korea; Osaka Univ, Grad Sch Dent, Dept Prevent Dent, Suita, Osaka 5650871, Japan; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu 41940, South Korea | ; Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57221686957; 57193342858; 57202916520; 56377838800; 35105905200; 7101649822; 7404777239 | parktj@gmail.com;ysjung0313@knu.ac.kr;sonkeunbada@gmail.com;ycbae@knu.ac.kr;kbsong@knu.ac.kr;amanoa@dent.osaka-u.ac.jp;cyh1001@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 4 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.56 | 2025-07-30 | 8 | 10 | chewing ability; cognitive function; elderly; MMSE; T-scan | RISK-FACTOR; TOOTH LOSS; OLDER-ADULTS; ORAL-HEALTH; DEMENTIA; IMPAIRMENT; MASTICATION; ASSOCIATION; MEMORY; LIFE | Chewing ability; Cognitive function; Elderly; MMSE; T-scan | Aged; Cognition; Cognitive Dysfunction; Humans; Mastication; Republic of Korea; Tooth Loss; South Korea; aging population; cognition; elderly care; health care; health services; mental health; tooth; aged; aging; Article; chewing gum; cognitive defect; controlled study; dementia assessment; demography; dental parameters; female; human; major clinical study; male; mastication; Mini Mental State Examination; Mini Mental State Examination Dementia Screening; multiple linear regression analysis; occlusion balance; questionnaire; rural area; South Korea; urban area; very elderly; cognition; cognitive defect; periodontal disease | English | 2021 | 2021-02 | 10.3390/ijerph18041996 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Objective Assessment of Sleep Patterns among Night-Shift Workers: A Scoping Review | In this scoping review of the literature, we identified the types and the parameters of objective measurements to assess sleep patterns among night-shift workers. We conducted a literature search using electronic databases for studies published from 1991 to 2020 and charted and summarized key information. We included 32 studies in the review. Polysomnography was used in 6 studies and wearable sleep detection devices were utilized in 26 studies. The duration of sleep assessment using the wearable devices ranged from 1 day to >= 4 weeks, and more than half of the studies collected data for >2 weeks. The majority of the studies used subjective questionnaires, such as the Karolinska Sleepiness Scale, Epworth Sleepiness Scale, and Pittsburgh Sleep Quality Index, in addition to objective sleep measurements. Total sleep time was the most common parameter, followed by sleep efficiency, sleep onset latency, and time or frequency of being awake. As the utilization of wearable devices to assess the sleep patterns of night-shift workers is expected to increase, further evaluation of device accuracy and precision, optimal data collection period, and key parameters is warranted. | Shin, Seunghwa; Kim, Su-Hyun; Jeon, Bomin | Andong Sci Coll, Dept Nursing, Andong 36616, South Korea; Kyungpook Natl Univ, Coll Nursing, Daegu 41944, South Korea; Kyungpook Natl Univ, Coll Nursing, Res Inst Nursing Sci, Gukchaebosang Ro 680, Daegu 41944, South Korea | 57224006486; 56664542600; 58461384500 | sswha@hanmail.net;suhyun_kim@knu.ac.kr;okddeolme12@hanmail.net; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 24 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.15 | 2025-07-30 | 6 | 6 | shift work schedule; sleep; sleep disorders; circadian rhythm; wearable electronic devices | ACTIGRAPHY; ALERTNESS; ADAPTATION; DISORDERS; QUALITY; DAYTIME; LIGHT; TRIAL | Circadian rhythm; Shift work schedule; Sleep; Sleep disorders; Wearable electronic devices | Circadian Rhythm; Humans; Sleep; Sleep Disorders, Circadian Rhythm; Sleep Quality; Wakefulness; Work Schedule Tolerance; assessment method; circadian rhythm; electronic equipment; sleep; working conditions; circadian rhythm; circadian rhythm sleep disorder; human; sleep; sleep quality; wakefulness; work schedule | English | 2021 | 2021-12 | 10.3390/ijerph182413236 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Perceived Preparedness of Dental Academic Institutions to Cope with the COVID-19 Pandemic: A Multi-Country Survey | Dental academic institutions are affected by COVID-19. We assessed the perceived COVID-19 preparedness of these institutions and the characteristics of institutions with greater perceived preparedness. An international cross-sectional survey of dental academics was conducted from March to August 2020 to assess academics' and institutional attributes, perceived preparedness, and availability of infection prevention and control (IPC) equipment. Principal component analysis (PCA) identified perceived preparedness components. Multilevel linear regression analysis assessed the association between perceived preparedness and fixed effect factors (academics' and institutions' attributes) with countries as random effect variable. Of the 1820 dental academics from 28 countries, 78.4% worked in public institutions and 75.2% reported temporary closure. PCA showed five components: clinic apparel, measures before and after patient care, institutional policies, and availability of IPC equipment. Significantly less perceived preparedness was reported in lower-middle income (LMICs) (B = -1.31, p = 0.006) and upper-middle income (UMICs) (B = -0.98, p = 0.02) countries than in high-income countries (HICs), in teaching only (B = -0.55, p 100 patients (B = -0.38, p < 0.0001). More perceived preparedness was reported by academics with administrative roles (B = 0.59, p < 0.0001). Academics from low-income countries (LICs) and LMICs reported less availability of clinic apparel, IPC equipment, measures before patient care, and institutional policies but more measures during patient care.

| ○ | ○ | Article | Popularity of Screen Golf in Korea and Its Sociocultural Meaning | The purpose of this study was to examine the popularity of screen golf, golf played using an indoor golf simulator, in Korea and to further explore its sociocultural significance. This study conducted a case study in which purposeful sampling was employed to recruit 15 participants. The results revealed that screen golf was popular in Korea because its facilities were easier to access; screen golf centers were found at convenient locations, and screen golf was more affordable than playing golf at the golf course. The combination of screen golf and the bang culture that is particular to Koreans has led them to accept the former as a familiar space for leisure activities. The results further revealed that screen sport has sociocultural significance in that its considerable popularity has led to the integration of virtual reality (VR) sports into daily life, thus making the division between sports and games less evident. Golf, a sport once considered as being an exclusive hobby for rich elites, has become popular among the general public, destroying the hierarchal notion that some sports harbor. This is meaningful as screen golf has played the role of an agent for sport socialization, encouraging people to participate in golf even on a course, unlike any other VR sport. Furthermore, this pastime has secured its position as a subculture in and of itself, becoming popular throughout the world. | Lee, Jung-Rae; Kwon, Ki-Nam | Kyungpook Natl Univ, Dept Leisure & Sports, Coll Ecol & Environm Sci, 2559 Gyeongsang Daero, Sangju Si 37224, Gyeongsangbuk D, South Korea | Lee, Jaetae/AAR-3317-2021 | 57371055100; 57370913700 | Jllee@knu.ac.kr;happyyear77@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 24 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.14 | 2025-07-30 | 3 | 4 | popularity; screen golf; sociocultural meaning; case study | Case study; Popularity; Screen golf; Sociocultural meaning | Golf; Humans; Leisure Activities; Republic of Korea; Sports; Korea; culture; sampling; sport; virtual reality; adult; Article; case study; cost; cultural factor; female; human; Korea; leisure; male; middle aged; recreation; risk factor; screen golf; socialization; virtual reality; golf; South Korea; sport | English | 2021 | 2021-12 | 10.3390/ijerph182413178 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Precautionary Behavior Practices and Psychological Characteristics of COVID-19 Patients and Quarantined Persons | Background: since the coronavirus disease (COVID-19) was first reported in 2019, South Korea has enforced isolation of patients with confirmed cases of COVID-19, as well as quarantine for close contacts of individuals diagnosed with COVID-19 and persons traveling from abroad, in order to contain its spread. Precautionary behavior practices and psychological characteristics of confirmed and quarantined persons were investigated for planning pandemic recovery and preparedness. Methods: this study was conducted with 1716 confirmed patients and quarantined persons in Daegu and Busan, regions where a high number of cases were confirmed during the early stage of the COVID-19 outbreak in South Korea. We collected online survey data from 23 April to 20 May 2020, in Daegu, and 28 April to 27 May 2020, in Busan, in cooperation with Daegu and Busan Infectious Disease Control Centers and public health centers in the regions. COVID-19 symptoms, pre-cautionary behavior practices, psychological states, and the need for improvement in isolation/quarantine environments were examined using an online survey. Results: compared to patients infected with coronavirus, quarantined persons engaged in more hygiene-related behaviors (e.g., hand washing, cough etiquette, and proper mask-wearing) and social distancing. COVID-19 patients had a strong fear of stigma, while quarantined persons had a strong fear of contracting COVID-19. Study participants responded that it was necessary to provide financial support and adequate information during isolation/quarantine. Conclusions: the study highlights the importance of precautionary behavior to prevent COVID-19 infection and the need to provide support (both psychological and financial) to patients and quarantined persons, to reinforce effective communication, social solidarity, and public health emergency preparedness (PHEP) in a pandemic situation. | Lee, Yubin; Kim, Byung-Woo; Kim, Shin-Woo; Son, Hyunjin; Park, Boyoung; Lee, Heeyoung; You, Myoungsoon; Ki, Moran | Seoul Natl Univ, Grad Sch Publ Hlth, Dept Publ Hlth Sci, Seoul 08826, South Korea; Natl Canc Ctr, Grad Sch Canc Sci & Policy, Dept Canc Control & Populat Hlth, Goyang 10408, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu 41944, South Korea; Dong A Univ, Coll Med, Dept Prevent Med, Busan 49201, South Korea; Hanyang Univ, Dept Prevent Med, Coll Med, Seoul 04763, South Korea; Seoul Natl Univ, Bundang Hosp, Ctr Prevent & Publ Hlth, Seongnam 13620, South Korea; Gyeonggi Publ Hlth Policy Inst, Seongnam 13605, South Korea | You, Myoungsoon/AAQ-5431-2020; Ki, Moran/R-6600-2019; lee, hy/GRS-0797-2022 | 57224187488; 55938165200; 8710731500; 57203048631; 7402834655; 7501482409; 57226057769; 6603678673 | ubeanee@snu.ac.kr;bero@ncc.re.kr;ksw2kms@knu.ac.kr;hjson@dau.ac.kr;hayejine@hanmail.net;wanderingstone@gmail.com;msyou@snu.ac.kr;moranki@ncc.re.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 11 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.49 | 2025-07-30 | 7 | 8 | COVID-19 pandemic; quarantine; isolation; public health emergency preparedness; online survey of patients and contacts | SARS; EXPERIENCE; CONTACTS; IMPACT | COVID-19 pandemic; Isolation; Online survey of patients and contacts; Public health emergency preparedness; Quarantine | COVID-19; Humans; Pandemics; Quarantine; Republic of Korea; SARS-CoV-2; South Korea; Taegu [South Korea]; Taegu [Taegu (ADS)]; Coronavirus; COVID-19; disease spread; Internet; mental health; population outbreak; psychology; public health; adult; ageusia; anosmia; Article; chill; coronavirus disease 2019; coughing; diarrhea; dyspnea; fear; female; fever; financial management; groups by age; headache; human; human rights; indigestion; isolation; major clinical study; male; mental health; myalgia; nausea; pandemic; physiological stress; population research; quarantine; scoring system; sex difference; sore throat; South Korea; epidemiology; pandemic | English | 2021 | 2021-06 | 10.3390/ijerph18116070 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sleep Problems among Disaster Victims: A Long-Term Survey on the Life Changes of Disaster Victims in Korea | This study aimed to assess sleep problems and their underlying factors in victims of disasters such as typhoons, heavy rains, fires, and earthquakes. Data from the long-term survey on life changes among disaster victims in 2019 obtained by the National Disaster Management Research Institute were used. The study included 1358 victims of natural and social disasters in Korea between 2012 and 2018. Sleep problems were assessed using a survey on subjective sleep quality and the use of sleeping medication. The data were analyzed using the chi-square test, t-test, and binominal logistic regression. The results showed that the factors affecting subjective sleep quality included disaster type, time elapsed after disaster, subjective health status, depression, and posttraumatic stress disorder. The factors affecting sleep medication use included age, time elapsed after disaster, and posttraumatic stress disorder. Therefore, interventions and support systems should be provided to prevent the prolongation of sleep problems. | Kim, Yujeong; Lee, Haeyoung | Kyungpook Natl Univ, Coll Nursing, Res Inst Nursing Sci, Daegu 41944, South Korea; Chung Ang Univ, Red Cross Coll Nursing, Seoul 06974, South Korea | ; Lee, Haeyoung/NRA-8461-2025 | 57200941945; 57205471062 | yujeongkina@knu.ac.kr;im0202@cau.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 6 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.42 | 2025-07-30 | 9 | 13 | sleep; disasters; natural disasters; posttraumatic stress disorder | Disasters; Natural disasters; Posttraumatic stress disorder; Sleep | Disaster Victims; Earthquakes; Humans; Quality of Life; Republic of Korea; Sleep Wake Disorders; Stress Disorders, Post-Traumatic; Korea; hypnotic agent; cognition; disaster relief; environmental risk; health risk; mental disorder; mental health; natural disaster; public health; adult; age; Article; controlled study; cross-sectional study; data analysis; depression; disaster victim; earthquake; female; fire; health status; health survey; human; hurricane; life event; major clinical study; male; natural disaster; posttraumatic stress disorder; sleep disorder; sleep quality; South Korea; earthquake; posttraumatic stress disorder; quality of life; sleep disorder | English | 2021 | 2021-03 | 10.3390/ijerph18063294 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Targeting Salmonella Typhimurium Invasion and Intracellular Survival Using Pyrogallol | Salmonella enterica serovar Typhimurium, an intracellular pathogen, evades the host immune response mechanisms to cause gastroenteritis in animals and humans. After invading the host cells, the bacteria proliferate in Salmonella-containing vacuole (SCV) and escapes from antimicrobial therapy. Moreover, Salmonella Typhimurium develops resistance to various antimicrobials including, fluoroquinolones. Treating intracellular bacteria and combating drug resistance is essential to limit the infection rate. One way of overcoming these challenges is through combination therapy. In this study, Pyrogallol (PG), a polyphenol, is combined with marbofloxacin (MAR) to investigate its effect on Salmonella Typhimurium invasion and intracellular survival inhibition. The Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of PG against Salmonella Typhimurium were 128 and 256 mu g/mL, respectively. The lowest fractional inhibitory concentration (FIC) index for a combination of PG and MAR was 0.5. The gentamycin protection assay revealed that PG (30 mu g/mL) alone and in combination with sub-MIC of MAR inhibited 72.75 and 76.18% of the invading bacteria in Caco-2 cells, respectively. Besides, the intracellular survival of Salmonella Typhimurium was reduced by 7.69 and 74.36% in treatment with PG alone and combined with sub-MIC of MAR, respectively, which was visualized by the confocal microscopy. PG has also shown to increase the intracellular accumulation of fluoroquinolone by 15.2 and 34.9% at 30 and 100 mu g/mL concentration, respectively. Quantitative real-time PCR demonstrated PG suppressed the genetic expression of hilA, invF, sipB, and acrA by 14.6, 15.4, 13.6, and 36%, respectively. However, the downregulation of hilA, invF, sipB, and acrA increased to 80, 74.6, 78, and 70.1%, in combination with sub-MIC of MAR, respectively. Similarly, PG combined with MAR inhibited the expression of sdiA, srgE, and rck genes by 78.6, 62.8, and 61.8%, respectively. In conclusion, PG has shown antimicrobial activity against Salmonella Typhimurium alone and in combination with MAR. It also inhibited invasion and intracellular survival of the bacteria through downregulation of quorum sensing, invading virulence, and efflux pump genes. Hence, PG could be a potential antimicrobial candidate which could limit the intracellular survival and replication of Salmonella Typhimurium. | Birhanu, Biruk Tesfaye; Lee, Eon-Bee; Lee, Seung-Jin; Park, Seung-Chun | Kyungpook Natl Univ, Coll Vet Med, Lab Vet Pharmacokinet & Pharmacodynam, Daegu, South Korea; Korea Inst Toxicol, Dev & Reprod Toxicol Res Grp, Daejeon, South Korea | Park, Seung-Chun/AAV-3388-2021; Lee, Jun Young/CAI-2335-2022; Lee, Jung Bok/HHZ-3200-2022; Birhanu, Biruk/F-1622-2017 | 56996190000; 57216526135; 58689440900; 7501832396 | lee.seungjin@kitox.re.kr;parksch@knu.ac.kr; | FRONTIERS IN MICROBIOLOGY | FRONT MICROBIOL | 1664-302X | 12 | SCIE | MICROBIOLOGY | 2021 | 6.064 | 24.5 | 1.37 | 2025-07-30 | 28 | 25 | intracellular inhibition; invasion; marbofloxacin; pharmacodynamic; pyrogallol | EPIGALLOCATECHIN GALLATE; PLANT POLYPHENOLS; ESCHERICHIA-COLI; EFFLUX PUMP; RESISTANCE; ENTERICA; VIRULENCE; COMPOUND; SYSTEM; EXPRESSION | intracellular inhibition; invasion; marbofloxacin; pharmacodynamic; pyrogallol | acridine efflux pump protein; invasion protein invF; marbofloxacin; pyrogallol; quinoline derived antiinfective agent; transcription factor; transcription factor rck; transcription factor sdiA; transcription factor sipB; transcription factor srgE; transcriptional regulator hilA; unclassified drug; antibacterial activity; Article; bacterial count; bacterial virulence; bacteriostatic activity; bacterium culture; binding affinity; binding site; cell invasion; cell invasion assay; cell survival; colony forming unit; confocal microscopy; controlled study; dose time effect relation; down regulation; drug accumulation; fractional inhibitory concentration index; gene expression; human; human cell; IC50; immune response; intracellular bacterium; intracellular transport; ligand binding; minimum bactericidal concentration; minimum inhibitory concentration; molecular docking; MTT assay; nonhuman; pharmacodynamic parameters; protein analysis; protein structure; quorum sensing; RAW 264.7 cell line; real time polymerase chain reaction; RNA extraction; Salmonella enterica serovar Typhimurium; survival rate | English | 2021 | 2021-02-02 | 10.3389/fmicb.2021.631426 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Associations between Physical Fitness, Complex vs Simple Movement, and Academic Achievement in a Cohort of Fourth Graders | This study analyzed the correlation between elementary school students' body composition, physical activity, physical fitness, movement ability, and academic achievement. Movements ranged from simple actions to complex movements requiring executive functioning. In total, 110 fourth graders (60 boys, 50 girls) participated in this experiment. Body composition (BMI, % of body fat), physical activity (pedometer), physical fitness (muscular strength, endurance, power, flexibility, and VO(2)max), and complex movement abilities (Illinois Agility test, soda pop hand test, and soda pop foot test) were measured. Regression modeling of body composition and fitness/activity variables was able to account for 30.5% of the variation of total academic scores in females, but only 4.3% in males. No individual tests were reliably correlated with multiple academic outcomes in males. However, hand and foot soda pop times, as well as Illinois Agility scores, were repeatedly correlated with academic outcomes in females, each correlating with 4 of the 6 academic scores. Body composition and physical activity level did not correlate with academic achievement, and simple physical fitness showed a low correlation with academic achievement in both boys and girls. On the other hand, complex, cognitively demanding movements such as the Illinois Agility, soda pop hand, and soda pop foot tests had consistent correlations with academic achievement in girls, but not in boys. | Ryu, Jong-Sik; Chung, Hae Ryong; Meador, Benjamin M.; Seo, Yongsuk; Kim, Kyung-O | Kyungpook Natl Univ, Dept Phys Educ, Daegu 41566, South Korea; Clayton State Univ, Coll Hlth, Hlth & Fitness Management, Morrow, GA 30260 USA; Georgia Southwestern State Univ, Coll Nursing & Hlth Sci, Exercise Sci, Americus, GA 31709 USA; Kent State Univ, Environm Physiol Lab, Kent, OH 44242 USA; Kyungil Univ, Dept Gerokinesiol, Kyungsan 38428, South Korea | 57218342739; 57209203979; 24067713000; 39362222500; 57222120091 | jsryu1984@gmail.com;hchung@clayton.edu;Benjamin.meador@gsw.edu;yseo@kent.edu;stem53006@gmail.com;kkim@kiu.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 5 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.35 | 2025-07-30 | 6 | 6 | academic achievement; elementary school student physical fitness; complex movement; simple movement | Academic achievement; Complex movement; Elementary school student physical fitness; Simple movement | Academic Success; Educational Status; Female; Humans; Illinois; Male; Mitochondrial Proton-Translocating ATPases; Physical Fitness; Illinois; United States; oligomycin sensitivity-conferring protein; proton transporting adenosine triphosphate synthase; academic performance; gender relations; health education; physical activity; primary education; regression analysis; student; academic achievement; Article; body composition; body fat; body mass; child; cognition; complex movement; controlled study; correlation analysis; elementary student; endurance; executive function; female; fitness; flexibility; gender; human; Illinois Agility test; male; maximal oxygen uptake; movement (physiology); muscle strength; physical activity; power; regression analysis; reliability; school child; sex difference; soda pop foot test; soda pop hand test; South Korea; academic success; educational status; fitness; Illinois | English | 2021 | 2021-03 | 10.3390/ijerph18052293 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | The Effect of Knowledge, Attitudes, and Practices of Korean Correctional Officers about COVID-19 on Job Stress | The purpose of this study was conducted to investigate the effects of corrective officers' knowledge, attitudes, and practices on job stress. The subjects of this study were 375 randomly selected male correctional officials working at five South Korean correctional facilities that had been affected by COVID-19. This study considered data collected with approval from 17 May 2021 to 14 June 2021. Knowledge, attitudes, practices, and job stress in relation to COVID-19 were assessed using a personal questionnaire. The data were analyzed using mean, standard deviation, t-test, one-way ANOVA, and post-test using Pearson's correlation coefficient. The job stress of participants was negatively correlated with knowledge, attitudes, and practices. Significant factors influencing job stress included knowledge and practices. These factors explained 38% of the variance. In this study, knowledge and practices were identified as influencing the job stress of correctional officers. These results are intended to contribute to the development of programs that can enhance the COVID-19-related knowledge and practices of correctional officers and reduce job stress. | Jung, Hyun-Ok; Han, Seung-Woo | Kyungpook Natl Univ, Coll Nursing, Dept Nursing, Daegu 41944, South Korea; Kyungil Univ, Dept Emergency Med Technol, Gyongsan 38428, South Korea | 57224449640; 57210797256 | juiris@korea.kr;swhan@kiu.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | INT J ENV RES PUB HE | 1660-4601 | 18 | 15 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2021 | 4.614 | 24.5 | 0.35 | 2025-07-30 | 6 | 6 | correctional institution; government official; job stress; knowledge; attitudes; practices; COVID-19 | RESIDENTS; EPIDEMIC | Attitudes; Correctional institution; COVID-19; Government official; Job stress; Knowledge; Practices | COVID-19; Cross-Sectional Studies; Health Knowledge, Attitudes, Practice; Humans; Male; Occupational Stress; Prisons; Republic of Korea; SARS-CoV-2; Surveys and Questionnaires; COVID-19; employment; knowledge; public attitude; adult; Article; attitude to health; coronavirus disease 2019; correctional staff; correlational study; data analysis; detention center; government employee; human; information processing; job stress; male; questionnaire; attitude to health; correctional facility; cross-sectional study; South Korea | English | 2021 | 2021-08 | 10.3390/ijerph18157779 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
