Led by the Cultural Heritage Administration, studies on the cultural heritage of railways have merely focused on modern registered cultural heritage and on excavating the cultural heritage of modern rail transportation. Endeavors of institutions relevant to railways to protect the cultural heritage of railways were not sufficiently made. Only the internal guideline to protect the cultural heritage of railways made by the railway corporation is being implemented. This study aims to assert the need to examine the protective measures of the heritage of railroad cars and to vitalize plans of conserving the heritage of railroad cars. Also, plans to protect the heritage of railroad cars and methods to invigorate schemes of protecting the heritage of railroad cars will be suggested. The current situation of protecting the heritage of railroad cars was investigated via a field trip. Through exploring overseas examples of protecting the heritage of the railroad cars, ways to vitalize plans of widely publicizing the heritage of the railroad cars with their historical values were suggested. Results showed that first, the way of openly exhibiting conserved railroad cars by setting up stands other than the way of exhibiting and conserving in one site was necessary. Second, in order to properly preserve and manage the cultural heritage of railways, railroad cars, much like natural monuments or intangible cultural properties, need to be perceived as cultural properties. Also, it is necessary to amend the Cultural Properties Protection Law to include railway heritage. Third, the perception of the cultural heritage of railways should be heightened, and SNS, blogs, and cafes need to strategically promote this heritage in order to increase the public's interest. Fourth, in addition to enacting legislations and gaining institutional support for the cultural heritage of railways, the budget to operate the responsible department, and employing staff for the heritage of railroad cars should be resolved as a priority in order to enhance the capability of managing this cultural heritage. In order to rationally protect the cultural heritage of railways and invigorate plans to protect the cultural heritage of railways, it is necessary to garner administrative and financial support, and enact the appropriate legislation. The heritage of railroad cars is priceless and has a social value in terms of regional icons, historic marks, and the record of life. It is considered that in this situation, the standard of amending both policy and the Cultural Properties Protection Law for the heritage of railroad cars should be urgently established.

In an epidemiological study of metal workers exposed to metalworking fluids (MWF), the prevalence time of Evolution, seasonal occurrence and clinical type of contact dermatitis were investigated. Compostional analysis of MWF with HPLC, dermatological examination and two consecutive questionnaire surveys were conducted. Study population was divided into two groups ; workers contact to cutting oil and workers contact to rust preventive oil. In the analysis of MWF, aliphatic hydrocarbons, having 12-20 carbons, was most common composition(49.04%) of cutting oil otherwise, major contents (90.99%) of the rust preventives oil were aliphatic hydrocarbons composed of 6-9 carbons. The frequency (point prevalence) of contact dermatitis(CD) was 7(12.7 per 100 subjects) in the dermatological examination of 55 workers. As the result of second survey for contact dermatitis, cumulative prevalence of oil working full-time and recent 1 year prevalence in two groups were 28.0, 16.7 and 15.1, 12.5 per 100 subjects. There were no difference in the prevalence of CD by oil, age, oil contact duration. Summer is the most common evolution season in workers exposed to cutting oil, but not in workers exposed to rust preventive oil. Major clinical type of CD was erythematous papules in both groups. It presents the importance of preventive measures that 51.1% suffer from contact dermatitis had medical care at their own expense, and 47.1% of them felt serious about their contact dermatitis. From the fact that 68.6% think cotton gloves protective apparatus, we emphasize the need for health education.
