Coronary artery calcification (CAC) on lung cancer screening low-dose chest CT (LDCT) is a cardiovascular risk marker. South Korea was the first Asian country to initiate national LDCT program, although CAC-related outcomes are poorly explored.
This research group (FROM) aimed to develop biomarkers for exposure environmental hazards and diseases, assess apply verify these in environmentally vulnerable areas. Environmentally areas—including refineries, abandoned metal mines, coal-fired power plants, waste incinerators, cement factories, areas with high particulate matter—along control areas, were selected epidemiological investigations. A total of 1,157 adults, who had resided over 10 years, recruited between June 2021 September...
Background: The aim of this study was to investigate whether type work is associated with anxiety and depression using the Hospital Anxiety Depression Scale (HADS).Additionally, we investigated impact number working hours on depression.Methods: A total 1774 workers participated completed HADS determine their levels depression.All subjects were employed at one two manufacturing plants for same company.Of all participants, 222 in office jobs 1552 jobs.Results: Results multivariate logistic...
The aim of this study was to investigate the association between insomnia and hearing impairment among workers exposed occupational noise.This included 809 male noise. participants underwent audiometric testing, their examined based on Insomnia Severity Index test. Hearing defined as threshold >25 dB level in range 1-4 kHz.According analysis covariance, it observed that pure tone audiometry thresholds at 1-2 kHz right ear 1 left were significantly higher with compared those no insomnia....
The aim of this study was to investigate whether shift work is related elevated risk coronary artery disease (CAD) by determining the calcium (CAC) score and presence stenosis using CT angiography (CCTA).In study, 110 male workers participated underwent a CCTA examination for CAC scoring, which represents plaque, were evaluated luminal stenosis. All participants working in same chemical plant, whom 70 worked day shifts 40 rotating shifts.In multivariate logistic regression analysis,...
In this study, we presented the national cancer statistics on incidence of hematologic malignancies in Republic Korea (ROK) over a period 20 years, from 1999 to 2018.We obtained data using Korean Statistical Information Service (KOSIS). For each malignancy, number cases, crude rate, and age-standardized rate were calculated, statistical trends confirmed by Poisson regression Joinpoint analysis.All investigated showed statistically significant increase years. The 20-year trend was as follows:...
Military personnel often use ammunitions that contain lead. The present study aimed to identify the risks for lead exposure and poisoning among workers at indoor firing ranges. A special health examination, including blood level (BLL) testing, was performed all 120 ranges of Republic Korea's Air Force, Navy, Armed Forces Athletic Corps. overall mean BLL 11.3 ± 9.4 µg/dL (range: 2.0-64.0 µg/dL). arithmetic professional shooters belong Corps 14.0 8.3 µg/dL, while those shooting range managers...
Dehydroepiandrosterone sulfate (DHEAS) is an endogenous steroid hormone produced by the adrenal gland. DHEAS has been suggested to play a protective role against psychosocial stress. The aim of this study was investigate association between job-related stress and blood concentrations according occupational factors among female nurses.A cross-sectional conducted 118 premenopausal nurses from 4 departments (operating room, emergency room [ER], intensive care unit, ward) university hospital....
Lead exposure is a known risk factor for cardiovascular disease (CVD), and coronary artery calcification (CAC) biomarker diagnosing atherosclerotic CVD. This study investigated the association between blood lead level (BLL) CAC using computed tomography (CT) angiography.This enrolled 2,189 participants from general population with no history or symptoms of All underwent CT angiography, health examination, BLL testing. The calcium score (CACS) was analyzed.The arithmetic mean 2.71 ± 1.26...
Cancer is a disease with high social costs, and policymaking through accurate statistics very important. This study presents the national cancer on incidence of urological cancers in Republic Korea over 22 years, from 1999 to 2020.
An outbreak of eye diseases occurred among workers at a poultry abattoir in South Korea from December 2012 to June 2013. epidemiological investigation the causative agent was conducted. The were given special health examination and workplace environmental monitoring performed. Workers with ocular symptoms subsequently underwent an ophthalmic examination.From total 41 workers, 26 (63.4 %) diagnosed keratoepitheliopathy by examination. Environmental revealed that ultraviolet (UV)...
To report the case of a fisherman who developed chronic mercury poisoning due to excessive consumption tuna while working on pelagic fishing vessel.A 48-year-old male deep-sea paresthesia and pain in both legs at sea.

In South Korea, the legal maximum working hours per week for medical residents is 88 hours, which are longer than those other occupations, and intensity of workload also remarkably high. Long job-related stress can worsen health status residents. This study aimed to analyze four-year annual checkup (AHC) data identify changes in their indicators.
This study inquired into any significant difference in blood lead levels (BLLs) among aircraft maintenance crews at the air-bases, each with a different aviation fuel use, and confirmed an environmental impact of leaded gasoline (AVGAS).This included total 256 male personnel, whom 105 used only AVGAS as their fuel, while 151 jet propellant 8 (JP-8), kerosene variety. BLLs were measured data on related factors obtained.The arithmetic geometric means personnel airbases that 4.20 microg x...
Objectives: An outbreak of acute febrile illness occurred in the Republic Korea Air Force boot camp from May to July 2011. epidemiological investigation causative agent, which was a highly infective nature, conducted. Methods: Throat swabs were carried out and multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay performed identify possible factors. Results: The mean age patients who had during study period 20.24 years. RT-PCR identified respiratory syncytial virus (RSV)...
For health care workers, immune management plays an important role in the protection against infectious diseases. This study investigated seroprevalence of measles, mumps, rubella, and varicella-zoster newly employed female nurses.
