Residency programs and the outlook for occupational and environmental medicine in Korea: Youngil Lee, Jungwon Kim, Yoomi Chae; Ann Occup Environ Med 2015;27:23. Published online September 25, 2015; DOI: https://doi.org/10.1186/s40557-015-0072-1

Abstract PDF PubReader ePub: Objectives
This study investigated the implementation of training courses and the overall outlook for occupational and environmental medicine (OEM) in Korea. We described the problems facing OEM residency programs in Korea, and reviewed studies dealing with the specialty of occupational health in developed countries in order to suggest directions of improvement for the OEM training courses.
Methods
We surveyed 125 OEM residents using a questionnaire in August 2012. A total of 23 questions about the training environment, residency programs, preferred institutions for post-licensure employment, and the outlook for OEM specialists were included in the questionnaire and analyzed according to the type of training institution and residency year. Responses from 88 residents (70.4 %) were analyzed.
Results
The major responsibilities of OEM residents were found to vary depending on whether they were trained in research institutes or in hospitals. OEM residents had a lower level of satisfaction with the following training programs: toxicology practice (measurements of biological markers, metabolites, and working environments), and OEM practice (environmental diseases and clinical training involving surgery). When asked about their eventual place of employment, OEM residents preferred institutions providing special health examinations or health management services. OEM residents reported a positive outlook for OEM over the next 5 years, but a negative outlook for the next 10 years.
Conclusions
Although a standardized training curriculum for OEM residents exists, this study found differences in the actual training courses depending on the training institution. We plan to standardize OEM training by holding a regional conference and introducing open training methods, such as an open hospital system. Use of Korean-language OEM textbook may also reduce differences in the educational programs of each training institution. Toxicology practice, environmental diseases, and clinical training in surgery are areas that particularly need improvement in OEM residency training programs.

Estimation of Demand and Supply for Occupational and Environmental Medicine Specialties in Korea (I): Estimation of Supply: Jungwon Kim, Yoomi Chae, Jonghan Leem; Korean Journal of Occupational and Environmental Medicine 2011;23(1):71-79. Published online March 31, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.1.71

OBJECTIVES
To estimate the supply of occupational and environmental medicine specialties in the target year of 2020.
METHODS
We adopted alternative projection models combined with a demographic method as a supply forecasting method. The model uses data selected primarily from the database of the Korean Society of Occupational and Environmental Medicine (KSOEM), a survey for certified members of KSOEM, audit data from the Ministry of Employment and Labor (MOEL) and Hospital Accreditation. We assumed five viable alternatives in supply forecasting.
RESULTS
Depending on the assumptions, the total occupational and environmental medicine specialties supply ranged from 706 by low-level supply estimates to 754 by high-level supply estimates in 2020. Among them, approximately 81% were estimated to engage themselves in agency for health management and periodic health examinations for workers exposed to hazards.
CONCLUSIONS
The study results suggest that the supply of occupational and environmental medicine specialties is related to the policy of MOEL. Further studies are needed concerning overall policy about health and safety and for the newly demanded market.

Estimation of Demand and Supply for Occupational and Environmental Medicine Specialties in Korea (II): Demand Estimation and Demand-Supply Balance: Yoomi Chae, Jungwon Kim, Jonghan Leem; Korean Journal of Occupational and Environmental Medicine 2011;23(1):80-88. Published online March 31, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.1.80

Abstract PDF

OBJECTIVES
To estimate the demand and demand-supply balances of occupational and environmental medical specialties (OEMS) in the target year of 2020.
METHODS
We adopted a new OEMS demand model based on the situations of periodic workers' health examination (PHE) agencies, health management agencies (HMA), and legal enforcement for health and safety systems in Korea. The model uses data selected primarily from the database of the Korean Society of Occupational and Environmental Medicine (KSOEM), a survey for certified members of KSOEM, statistics and internal documents from the Ministry of Employment and Labor (MOEL).
RESULTS
From the data and assumptions, newly demanded OEMS were 193 for workers who had received PHE, and 205 based on total workers for PHE in 2020 for PHE. But no OEMS for HMA area is demanded. Comparing with the calculated numbers of supply estimates, the demand was slightly higher, but could be balanced if MOEL kept consistent and unchanging policies.
CONCLUSIONS
The study results suggest that the demand-supply balance of OEMS is mainly influenced by the policy of MOEL. Further studies are needed examining more detailed data and statistics about PHE agencies, HMA and considering MOEL policies are needed to configuring more sophisticated and need-included estimation.

Development of Quality Assessment Domain and its Priority in Korea's Occupational Health Services: A Special Health Examination: Yoomi Chae, Sangchul Roh, Sukchul Jung; Korean Journal of Occupational and Environmental Medicine 2010;22(3):210-220. Published online September 30, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.3.210

Abstract PDF

OBJECTIVE: The purpose of this study was to develop a quality assessment domain and to determine its priority in Korea's Occupational Health Services.
METHODS
We designed the study in a 3 phase approach. The first phase of the process encompasses making a list of measures for quality assessments by a thorough review of the literature. The second phase emcompassed the development of inclusion and priority criteria. The third phase of survey development was conducted during August 2008 and a questionnaire was administered to occupational health physicians covering 58 subjects.
RESULTS
Finally we investigated 40 quality assessment measures, including 2 for structural domain, 17 for process domain, 21 for result domain in occupational health service. The 40 quality assessment measures divided into 2 parts. The early quality assessment part was 14 measures that including 8 measures for process domains and 5 measures for result domains.
CONCLUSION
We investigate a quality assessment domain and determined the priorities of the occupational health service in Korea.

Comparing the Characteristics of CTS by the Frequency of Exposure to Wrist-burdening Work: CTS Surveillance System, 2001-2004: Sukchul Jung, Yoomi Chae, Sangchul Roh; Korean Journal of Occupational and Environmental Medicine 2010;22(2):85-94. Published online June 30, 2010; DOI: https://doi.org/10.35371/kjoem.2010.22.2.85

Abstract PDF

OBJECTIVE: We investigated the differences among the patients who were diagnosed with carpal tunnel syndrome according to the frequency of exposure to wrist-burdening work by using carpal tunnel syndrome surveillance system.
METHODS
The study subjects were a total of 855 patients from 1,017 patients who were diagnosed with carpal tunnel syndrome in 9 university hospitals from May, 2001 to October, 2004, and we excluded 161 patients who had no clear information for their occupational status. The subjects were classified into three groups according to four types of wrist-burdening work: 1) repetitive use of wrists, 2) inappropriate posture of the hand, 3) use of vibrating tools, and 4) overpressure work on the hand or palm, - as defined in the operational definition by the National Institute for Occupational Safety and Health (NIOSH). The subjects with two or more types of wrist-burdening work were classified as 'high risk group', the subjects with one type of wrist-burdening work were classified as 'intermediate risk group', and the subjects with none of the types of wrist-burdening work were classified as 'low risk group'. We used chi-square test, Fisher's exact test and ANOVA for comparing the characteristics according to the 3 subgroup.
RESULTS
The mean age in the high risk group was the lowest(53 years), and there was a significant difference among the groups for the mean age(p<0.05). The high risk group included the most males with 39(22.0%). The subjects in the high risk group had significantly more jobs in agriculture.forestry.fisheries, factory work, and simple labor and less comorbidities, including diabetes and rheumatoid arthritis(p<0.05). The subjects in the intermediate risk group had a higher proportion of service workers. There were significant differences for the symptoms of carpal tunnel syndrome according to the frequency of exposure to wrist-burdening work. The subjects in the high risk group showed the highest proportion of work-related aggravation of symptoms with 88(76.5%) and the highest mean number of days absent from work(6 days) as related to carpal tunnel syndrome.
CONCLUSION
Worker in agriculture.forestry.fisheries, factory work, and simple labor showed significantly more frequent carpal tunnel syndrome, and so management strategies are needed to prevent them from developing carpal tunnel syndrome.

Pulmonary Function Changes of Ozone Exposed Workers in a Film Manufacturing Company: Yoomi Chae, Hyunjoo Kim, Sangchul Roh; Korean Journal of Occupational and Environmental Medicine 2007;19(3):215-222. Published online September 30, 2007; DOI: https://doi.org/10.35371/kjoem.2007.19.3.215

Abstract PDF

OBJECTIVES
To investigate the pulmonary function changes of ozone exposure in Corona and Slitter workers exposed to an ozone level ranging from 0.022~0.061 ppm.
METHODS
Forty-two subjects were exposed for 8hrs to ozone every day. We perfomed pulmonary function testing immediately before and after work and self-administered, portable peak flow meter measurements were self-conducted by the workers over a 5-day (Monday to Friday) period.
RESULTS
Ozone concentrations in the workplace ranging from 0.050~0.061 ppm at Corona and 0.022~0.023 ppm at Slitter in 2006. A small decrement in forced-vital capacity were observed among Corona workers from 93.9% to 91.3% (p=0.012) and also in employment duration below ten years. We found no significant differences in before and after FVC and FEV1 among Slitter workers. All daily (Monday to Friday) peak expiratory flow rates declined in magnitude after two days of ozone exposure, compared with first day exposure.
CONCLUSION
We concluded that daily ozone exposure in the workplace slightly decreased pulmonary function and that PEFR variability is greatest on the 2nd day of ozone exposure.
