BACKGROUND There were several suicide events of subway drivers in Korea. The aim of this study is to explore work-related factors associated with suicide ideation among subway drivers. METHODS We analyzed data from 980 male subway drivers. A section of the Korean version of the Composite International Diagnostic Interview (K-CIDI 2.1) was administered by trained interviewers to judge whether ...

The number of subway suicides in Vienna increased dramatically between 1984 and mid-1987. In the second-half of 1987 there was a decrease of 75% which has been sustained for 5 yr. This reduction in subway suicides began when a working group of the Austrian Association for Suicide Prevention developed media guidelines and initiated discussions with the media which culminated with an agreement to...

We surveyed 7318 customers from 275 randomly selected restaurants of 11 fast food chains. Participants purchased a mean of 827 calories, with 34% purchasing 1000 calories or more. Unlike other chains, Subway posted calorie information at point of purchase and its patrons more often reported seeing calorie information than patrons of other chains (32% vs 4%; P<.001); Subway patrons who saw calor...

Abstract Urban subway system, as an important type of urban transportation infrastructure, can provide mass mobility service and help address sustainability challenges such traffic congestion air pollution. The continuous construction subways, however, causes large amounts materials embodied greenhouse gas (GHG) emissions. In this study, we characterized the patterns development, material stock...

Increasingly, many American fast food restaurants are marketing their food as being healthier, often by introducing new menu items that have less fat, fewer calories, and that fit into a broader range of nondiscretionary categories of the food pyramid. However, no fast food restaurant has focused on the “healthiness” of its products to the extent that Subway Restaurant has over the past near de...

With the rapid progress of modern cities, the railway construction must be developing quickly in China.As a typical high-density country, shopping center on the subway should be one important factor during the process of urban development. The paper discusses the influence of the layout of shopping center on the subway, and put it in the time and space’s axis of Shanghai urban development. We u...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

Smart transportation system is a cross-field research topic that involves both the organizations manage large-scaled and individual end-users who enjoy these services. Recent advancement of machine learning-based algorithms has either enabled or improved wide range applications due to its strength in making accurate predictions for complex problems with minimal amount domain knowledge great abi...
