The ondol is a uniquely Korean system of providing warmth to room. The ondol rooms never use daily life furniture because the ondol warms the floor surface where people sit. Finally, the ondol floor changed the traditional housings inner space. Before use ondol where daily life furnitures[sang(상) and Tap(탑)] are installed in the room. The origin of daily life furnitures are the ancient tomb mural of Koguryo Period. The daily life furniture can be classified as three large groups in the ancient tomb mural of Koguryo. First, a single seat[Jowa-sang(좌상)] of set up a screen[병풍]. The second, It make possible Many peoples take a seat with no decoration seat[Tap(탑)]. The third, uptodately table and chairs. A radical difference between sang(상) and Tap(탑) whether set up a screen[병풍]. The meaning of sang(상) and Tap(탑) in Koguryo ancient tomb provided Oksa-jo[옥사조] in Samkuk-sagi[삼국사기] with several valuable leads to help solve the sang(상)'s meaning. Furthermore, It will be start ponit of study on constructive shape of inner space in those days.

Background: We assessed the cancer risks of four different Finnish asbestos-exposed cohorts. We also explored if the cohorts with varying profiles of asbestos exposure exhibited varying relative risks of cancer. Methods: The incident cancer cases for the asbestos-exposed worker cohorts were updated to the end of 2012 using the files of the Finnish Cancer Registry. The previously formed cohorts consisted of asbestos mine workers, asbestosis patients, asbestos sprayers, and workers who had taken part in a screening study based on asbestos exposure at work. Results: The standardized incidence ratio (SIR) for mesothelioma varied from about threefold to > 100-fold in the different cohorts. In the screening cohort the SIR for mesothelioma was highest in 2003-2007, In other cohorts it was more constant in 5-year period inspection. The SIR for lung cancer was about twofold to tenfold in all except the screening cohort. Asbestos sprayers were at the highest risk of mesothelioma and lung cancer. Conclusion: The SIR for mesothelioma is high in all of the cohorts that represent different kinds of asbestos exposure. The smaller SIR for mesothelioma in the screening cohort with lowest level of asbestos exposure might suggest dose-responsiveness between asbestos exposure and mesothelioma. It does seem that the highest risk of lung cancer in these cohorts except in the youngest of the cohorts, the screening cohort, is over. The highest SIR for lung cancer of the asbestosis patient and sprayers cohort is explained by their heavy asbestos exposure.

The increasing prevalence of inactivity and obesity, along with aging, has implications on work capacity of labor force. This study reports the relationships between activity level and BMI by age with objectively measured physical workload. Data were examined from a sample of 19 481 Finnish employees using an estimate of minute-to-minute oxygen consumption based on R-R interval recordings. The mean estimated %VO₂max during the working day was 12.1 (±3.6) and 15.1 (±4.5)% for men and women, respectively. Based on a linear model, the mean %VO₂max increased by 1.5%-unit per 10-year increase in age, by 2.1%-unit per 5 kg/㎡ increase in BMI, and decreased by 1.6%-unit if improving physical activity class by two (p < 0.001 for all). Overweight and obesity, together with inactivity, notably increases workload throughout the career, even though at young adulthood, the daily workload is almost the same for each person regardless of the BMI, activity level, or gender. This study highlights the importance of regular physical activity and normal weight in protecting the worker from excessive physical (cardiovascular) workload during the whole working career.

The study is intended to produce a modern Cheollik style one-piece dress that stays within the traditional concept of beauty. Specially, the study focuses on Cheollik of the Joseon Dynasty among various traditional costumes as its motif. As the Joseon Dynasty changed, the forms of Cheollik changed with it. People of all classes from the commoners to king wore it. Cheolik was different from other traditional costumes because the top and bottom were connected and so it was an easy to wear one-piece clothing. Initially, the ratio of upper and lower parts was one to one, but later on, the ratio changed to 1:2 as the topcoat became wider and length of the skirt was lengthened. Diverse types of pleat emerged such as fine pleat, opposite pleat and long pleat. Collar and string were also diversified and studied by applying the components. To study it, the author considered the previous studies about Cheollik first. Then, the Cheollik of the Joseon Dynasty was reproduced. Thirdly, with the motif of Cheollik components, the materials suitable to a one-piece dress design were selected, dyed naturally. Finally, One piece dress design was utilized by using the components and features of Cheollik. 8 pieces of one-piece dresses were made as an ordinary dress and the materials such as ramie, Oksa, hemp, silk, Yeon-hwamun dan and artificial silk were used. Hopefully, other traditional costumes can develop as a practical and ordinary dress.
