  • Background: The study was designed to assess the changes in working conditions through a comparative analysis of the characteristics of working conditions in 2006 and 2010. Methods: We performed a comparative analysis of the data related to the first Korean Working Conditions Survey (KWCS) and the second KWCS in the categories of demographic characteristics, quality of labor, exposure to hazards, and health problems. Results: From our analysis of the demographic characteristics, we saw an increase in labor force participation rate of women and elderly people. As a result of the investigation with regards to working hours, the ratio of employees who worked for ${\geq}49$ hours per week was decreased and the ratio of employees who worked for ${\geq}40h/wk$ increased. As for exposure to hazards, exposure to tobacco smoke notably decreased in 2010 compared with 2006. With regards to health problems, there was a sharp increase in the number of people who complained of muscle pain in their arms and legs. Conclusion: KWCS data included many aspects of working conditions as a nationwide sample. In addition, because this is a periodic nationwide survey, the labor force, working hours, harmful factor exposure, and the change in health problems characteristics according to the flow of time could be investigated. The information comparing the main results of the first survey conducted in 2006 and the second survey conducted in 2010 obtained through this study can be used as an important base material for the establishment of the national policy.

  • Objective: This study was designed to estimate the precise nationwide number of those who used humidifier disinfectants (HDs) and experienced specific health effects, including death, due to exposure to HDs in Korea between 1994 and 2011. Methods: A total of 5,000 households (15,472 people) were surveyed by stratifying the sample with a design that is equivalent to nationally approved household systematic sampling and face-to-face interviews from October 16, 2019 to December 30, 2019. Results: The proportion of use of humidifier disinfectants at home was 18.4% (2,844/15,472 people) and the proportion of those who experienced health effects among those who were exposed to HDs was 10.7% (303/2,844 people). Based on these factors, it was estimated that 8.94 million people (95% CI=8.25-9.63 million) were exposed to HDs and 0.95 million people (95% CI=0.87-1.02 million) experienced health effects, which means almost one in five and one in fifty Koreans respectively. The estimated number of deaths from HDs were 20,366 people (95% CI=18,801-21,931). Conclusion: The survey was large and analyzed a representative sample across the country, so this estimation of the nationwide population exposed and at risk to HDs is more accurate and reliable than previous studies. However, it is necessary to confirm whether results similar to those of this study can be reproduced through a survey using a cross-sectional survey at the national level. In particular, a survey focused on death cases is needed.

  • Objectives: Season of birth, an exogenous indicator of early life environment, has been related to higher risk of adverse psychiatric outcomes but the findings for Alzheimer's disease (AD) have been inconsistent. We investigated whether the month or season of birth are associated with AD. Methods: A nationwide nested case-control study including all community-dwellers with clinically verified AD diagnosed in 2005 to 2012 (n=70 719) and up to four age- sex- and region of residence-matched controls (n=282 862) residing in Finland. Associations between month and season of birth and AD were studied with conditional logistic regression. Results: Month of birth was not associated with AD (p=0.09). No strong associations were observed with season (p=0.13), although in comparison to winter births (December-February) summer births (June-August) were associated with higher odds of AD (odds ratio, 1.03; 95% confidence interval, 1.00 to 1.05). However, the absolute difference in prevalence in winter births was only 0.5% (prevalence of those born in winter were 31.7% and 32.2% for cases and controls, respectively). Conclusions: Although our findings do not support the hypothesis that season of birth is related to AD/dementia risk, they do not invalidate the developmental origins of health and disease hypothesis in late-life cognition. It is possible that season does not adequately capture the early life circumstances, or that other (postnatal) risk factors such as lifestyle or socioeconomic factors overrule the impact of prenatal and perinatal factors.

  • This study was conducted to investigate the isolation prequency, serotypes, and related epidemiological properties of 341 Salmonella spp from domestic poultry and environmental samples during the period 1993-1995. A total of 1,918 samples was collected during the three years period in nationwide. Most of Salmonella spp were isolated from the intestinal contents of poultry, especially cecal(46.0%) and rectal(35.8%) contents. Among the tested samples, rat(28.5 %) was the most predominant Salmonella reservoirs and followed by duck(24.8%), broiler(18.8%), layer(14.8%) and feed(7.1%), in order. More than twelve Salmonella serovars were identified among the 341 Salmonella isolates. The most prevalent serotypes isolated from non-human sources were S enteritidis (22.3%) and S pullorum (21.9%), S muenchen (13.9%), S typhimurium (12.6%), S gallinarum, S meleagridis, S heidelberg, and S senftenberg were followed, in order. In layer chickens, S pullorum (26.0%) was the most predominant serotype but S muenchen (33.0%) was in broiler chickens, S enteritidis (28.4%) was in ducks, and S typhimurium (60.0%) was in rats, respectively. As a results, S enteritidis was identified as the most prevalent serotype in non-human Salmonella isolates in Korea during the period 1993-1995. A preliminary study on the phage typing of 19 S enteritidis selected from the nationwide scale was shown that S enteritidis phage type(PT) 4 was the most predominant PT, and SEPT 1, SEPT 6a, SEPT 7 and SEPT 7a variant were also found in the same period.

  • This study has surveyed and analyzed in 2005 S/S domestic men's street fashion by using the Web-SFAS system that was developed and completed in the earlier research. Total of 270 men who were sensitive to fashion were surveyed around 5 nationwide cities and 9 commercial zones. The analysis results of the questionnaire and image survey in 2005 S/S for each commercial zone was shown as follows. 1. The most interest in producing fashionable shape when they go out was in the order of clothes>hair style>shoes and it was found that the proper reason for visiting the commercial zone was to meet with friends>watching movies>shopping etc. 2. T-shirts were most preferred as upper garments and as for bottoms, blue jeans were preferred. Black, gray, and white colors were most preferred and blue color was most preferred primarily due to the preference for blue jeans. The color image was proven mainly modem and light tone, comfortable and casual items were preferred. An active comfort casual image emphasized with activeness by coordinating comfortable T-shirts or shirts with blue jeans were most preferred in 9 areas. 3. A clear difference was confirmed in color by commercial area. Blackish color was most prevalent in Daehakro whereas simple color was mostly shown around Hongik University area. Bright and unique colors such as green and violate were dominant at Dae-Gu Dongseongro, and basic colors such as white and black were preferred in Masan Hapseong-dong and Changwon Sangnam-dong. Through the results of nationwide street fashion survey, the each commercial zone has unique characteristics in fashion trend even in the same city, rather than the regional difference in Seoul and local city.

  • Pollen is very important causing factor for allergy such as allergic rhinitis, allergic conjunctivitis, and asthma, and pollen allergy has a remarkable clinical impact all over Korea. The main pollination period covers about half the year, from spring to autumn, and the distribution of airborne pollen taxa of allergological interest is related to pollen season dynamics. Korean academy of pediatric allergy and respiratory diseases (KAPARD) has evaluated the pollen characteristics and nationwide pollen count for over 10 years since 1997. Airborne particles carrying allergens were collected daily from nationwide 8 stations (Seoul, Guri, Cheongju, Daegu, Kwangju, Busan, Kangneung, and Jeju) by using 7 days-Burkard sampler (Burkard Manufacturing Co Ltd, Hertfordshire, UK) in South Korea (July 1, 1997-June 30, 2007). They were counted and recorded along with the meteorological factors daily. Tree pollen is a major airborne allergen in spring, grass is most common in summer, and weed pollen is major pollen in autumn in Korea. There has two peak seasons for pollen allergy, as summer and autumn. There is some evidence suggesting that the prevalence of allergic diseases in Korea has been on the increase in the past decade. However, recent findings of the phase I and II studies of the international Study of Asthma and Allergies in Childhood (ISAAC) study showed the absence of increases or little changes in prevalence of asthma symptoms and diagnosis rates in Korea, whereas the prevalence of allergic rhinitis and atopic dermatitis were increased. We reported the evidence that sensitization rate to weed pollen has been increased yearly since 1997 in childhood. Climate change and air pollution must be the major causing factors for the increase of pollen counts and sensitization rate to pollen. Climate change makes the plants earlier pollination and persisting pollination longer. In conclusion, data on pollen count and structure in the last few years, the pathogenetic role of pollen and the interaction between pollen and air pollutants with climate change gave new insights into the mechanism of respiratory allergic diseases in Korea.

  • Purpose: The purpose of this study was to analyze and assess the current situation of Korea's school health education program and to establish measures to efficiently carry out school health education in Korea. Method: The survey was conducted through the internet with the health educators of elementary, middle, and high schools nationwide to assess the current condition of school health education programs, and 2,459 samples were collected which accounted for 23.4% of the total respondents. Results: According to school health educators on the enforcement of health education, the higher the education became, the less the health education was enforced. The enforcement rate was 96.9% in elementary schools, 76.7% in middle schools, and 67.3% in high schools. The major reasons were found as difficulty in securing class time (54.5%) and other excessive workloads (20.9%). As a result of the health education awareness survey, over 99% answered that health education is needed, over 80% answered that the education requires independent health textbooks, and over 95% answered that health educators are suitable for the person in charge of the education. Conclusion: This study will be a useful in establishing a detailed policy on enhancing school health education in the future.

  • 2003.1.25 인터넷대란 이후 정부는 국가위기관리차원에서 사이버안전확보에 심혈을 기울이고 있으나 현실은 국가안보위기 및 이와 관련된 정보ㆍ사이버위협에 대한 조기경보 및 위기평가체계가 미비하여 사이버위기 위협 발생 이후 수동적으로만 대응하고 있는 형편이다. 따라서 이런 한계를 극복하기 위해서는 보다 자동화되고 포괄적인 범국가 차원의 사이버위기 평가체계 구축이 필요한 것으로 판단된다. 이에 본 논문 특히 이벤트데이터 관련 최근 기술발전 동향을 추적하였으며, 특히 동 기술을 사회과학분야의 위기관리이론 및 모델들과 결합시켜 사용할 경우 국가사이버안보 평가목적 종합정보화시스템 개발이 가능성할 것으로 판단했다. 비록 사이버위협 같이 그 속성상 매우 신속ㆍ광범 위하게 발생되는 사건에 대한 정확한 예측은 어려울 수 있으나 이들 패턴을 체계적으로 유형화하고 각각에 대한 대응책을 시나리오형태로 제시하는 일은 가능할 것으로 보여 궁극적으로 국가사이버안보 및 위기관리 노력에 크게 기여할 수 있을 것으로 예상된다.
