VDT 작업자의 작업관련성 근골격계장애 : 일반 대조군과의 비교연구 Comparison with control groups
권호장,김돈규 단국대학교 1998 論文集 Vol.33 No.-
A cross-sectional study was conducted to assess the prevalence of the work-related musculoskeletal disorders(WRMSD) among employees using video display terminals. The study included 113 female telecommunication employees from three companies and control groups of housewives and office ladies. Information on demographics, individual factors were obtained by self-administered questionnaire. Cases of WRMSD were defined as one or more symptoms(e.g. pain, aching, stiffness, burning, numbness, or tingling) in one of the four upper extremity joint area(nect, shoulder, elbow, hand/wrist) which lasted more than 1 weeks or occurred at least once a month within the past year. Shoulder symptoms(71.7%) were the most frequently reported during the current week, followed by neck(68.1%), hand and wrist(60.2), and elbow symptoms(31.9%) in VDT operators. But in housewives and office ladies, the symptom prevalence was much lower than VDT operators for each location. Neck symptoms were correlated with the level of education and shoulder symptoms were correlated with the location of office. This results suggest of high prevalence of musculoskeletal disorders of the upper extremities among VDT workers.

The Goseong abandoned mine accident was a typical case of long-term sequela resulting from environmental disruption during the rapid economic development of Korea. While the final conclusion of epidemiologic investigation was that residents surrounding the abandoned mine were simply exposed to cadmium from the abandoned mine without any patient contracting 'itai-itai' disease, not only did residents around the abandoned mine suffer enormous psychological and economic damage, but people in neighbouring communities did as well when the entire area was stigmatized as an contaminated area. Environmental civic groups and the government worked together to solve the problem by forming a joint committee which held the right of decision in any matter to be determined. By inviting all the stakeholders to participate in the joint committee, a transparent investigation was guaranteed and the results of investigation and recommendations to solve the problem were accepted by all involved. Even though the environmental health division in Ministry of Environment has developed considerably and built up a capacity to deal with environmental accidents, the process which was adopted to solving the Goseong abandoned mine accident can be useful to settle environmental health issues with severe conflicts among stakeholders.

Asian dust, called Hwangsa in Korean, is windblown dust originating from the desert areas of China and Mongolia. Public concern on the possible adverse health effects of Asian dust has increased recently. Some experimental studies have reported that Asian dust aggravates the allergic response and induces cytotoxicity by promoting the release of reactive oxygen spe-cies. Asian dust may potentiate common cold symptoms associated with rhinovirus infection by enhancing inflammatory cytokines and increasing viral replication. In many epidemiologic stu-dies conducted not only in Korea but also in Taiwan and Japan, Asian dust exposure has been reported to be associated with an increase in mortality and hospital visits and admission due to cardiovascular and respiratory disease as well as increased respiratory symptoms and decrea-sed pulmonary function. The frequency and scale of Asian dust events are expected to increase due to environmental change such as desertification in northern China and climate change. We need an Asian dust preparedness strategy including monitoring of dust-related health outcomes as well as an enhanced Asian dust forecasting system to protect people from the effects of Asian dust events.

설문지에 의한 대기오염의 호흡기계 증상 발현에 관한 조사연구
권호장,조수헌,김선민,하미나,한상환,Kwon, Ho-Jang,Cho, Soo-Hun,Kim, Sun-Min,Ha, Mi-Na,Han, Sang-Hwan 대한예방의학회 1994 예방의학회지 Vol.27 No.2
A cross-sectional study was conducted in an effort to investigate the effect of air pollution on respiratory symptoms. Two groups of female aged more than 20 living in the unpolluted rural area of Taebul (n=159) and urban area of Taegu (n=140) were selected. The ATS-DLD-78 questionnaire was translated into Korean and administered with minor modification. The proportion of smoker was less than 1% in both area. Exposure to smoking and higher educational level were more frequent in Taegu. Age-adjusted prevalence rates of 'chronic cough', 'chronic sputum', 'wheezing', and 'dyspnea' were higher in Taegu than in Taebul. In particular, the prevalence rate of 'chronic sputum' in Taegu was found to be higher, which was statistically significant. Exposure to smoking and education level were not concerned with all respiratory symptom prevalence rates. In conclusion, this study Indicates that an urban factor is related to the rates of respiratory symptoms in Korea.

Objective: Attention deficit hyperactivity disorder (ADHD) is common disorder of the school-age population. ADHD is familial and genetic studies estimate heritability at 80–90%. The aim of the present study was to investigate the association between the genetic type and alleles for gamma-aminobutyric acid receptor subunit beta-3 (GABA3) gene in Korean children with ADHD. Methods: The sample consisted of 180 ADHD children and 159 control children. We diagnosed ADHD according to DSM-IV. ADHD symptoms were evaluated with Conners’ Parent Rating Scales and Dupaul Parent ADHD Rating Scales. Blood samples were taken from the 339 subjects, DNA was extracted from blood lymphocytes, and PCR was performed for GABA3 rs2081648, rs1426217 and rs981778 Polymorphism. Alleles and genotype frequencies were compared using the chi-square test. We compared the allele and genotype frequencies of GABA3 gene polymorphism in the ADHD and control groups. Results: This study showed that there was a significant correlation among the frequencies of the rs2081648 (OR=0.71, 95% CI=0.51–0.98, p=0.040) of alleles of MAO, but the final conclusions are not definite. Follow up studies with larger patient or pure subgroups are expected. Conclusion: These results suggested that GABA3 might be related to ADHD symptoms.
