Due to the variability in the geometry of underground openings and ground behavior, point measurements often fail to capture the true movement of mine workings. Photogrammetry is a potentially fast, cheap, and precise supplemental measurement tool in comparison to extensometers, tape measures, or laser range meters, but its application in underground coal has been limited. The practical use of photogrammetry was tested at the Safety Research Coal Mine, National Institute for Occupational Safety and Health(NIOSH). A commercially available, digital single-lens reflex(DSLR) camera was used to perform the photogrammetric surveys for the experiment. Several experiments were performed using different lighting conditions, distances to subject,camera settings, and photograph overlaps, with results summarized as follows: the lighting method was found to be insignificant if the scene was appropriately illuminated. It was found that the distance to the subject has a minimal impact on result accuracy, and that camera settings have a significant impact on the photogrammetric quality of images. An increasing photograph resolution was preferable when measuring plane orientations; otherwise a high point cloud density would likely be excessive. Focal ratio(F-stop) changes affect the depth of field and image quality in situations where multiple angles are necessary to survey cleat orientations. Photograph overlap is very important to proper three-dimensional reconstruction, and at least 60% overlap between photograph pairs is ideal to avoid unnecessary post-processing. The suggestions and guidelines proposed are designed to increase the quality of photogrammetry inputs and outputs as well as minimize processing time, and serve as a starting point for an underground coal photogrammetry study.展开更多

This is done through an efficient use of existing sources of explicit and tacit knowledge in the field of vocational occupational safety and health (OSH) training. This project identifies three specific research steps for the development of the knowledge management framework of the information technology-based approach for improving occupational safety training of young workers, including: (1) the development of the conceptual model of the flow of explicit knowledge of OSH; (2) evaluation of the effectiveness of formal and explicit knowledge sources for OSH and training methods using these sources in the context of attitudes towards health and safety at work; and (3) verification of the proposed model of vocational training with the use of combined explicit and hidden knowledge. The proposed framework includes consideration of the effectiveness of the formal and informal sources of safety knowledge. A mapping from the formal sources of explicit knowledge about the occupational safety to expected attitudes (hidden knowledge) towards OSH outcomes, including emotional, cognitive, and behavioral aspects has been used. The above framework should help to improve the system of vocational training for young workers in Poland.展开更多

In 2011, the Finnish Union of Health and Social Care Professionals--Tehy implemented a poster campaign targeted at the users of healthcare services, as well as healthcare staff. Representatives of local trade unions, as well as safety representatives, reported that the campaign was relevant. Most employers had a favorable attitude toward distributing campaign posters at the workplace. Raising this issue, which increases the mental burden of work and risks occupational safety at the workplace, helps to achieve improvements. Following the poster campaign, Tehy conducted an electronic survey in early 2012 about the impacts of the campaign among representatives of local trade unions (N= 279) and safety representatives (N = 278). The campaign resulted in some working environment improvements, as well as an increase in reporting situations involving violence. On a more worrying note, the provision of workplace-level training on managing violent situations did not increase.展开更多

HIPS is the first system which KOSHA and KGS (Korea Gas Safety Corp.) officially required to attach SIL verification report in the Process Safety Report. KOSHA and KGS uniformly require SIL3 for HIPS and require to configure the safety instrumented function to meet SIL3 requirement. The flare system with SIL3 application should have the interlocks to shut off the heat source in case of high pressure from tower, the cooling system failure and the power failure. KOSHA and KGS admit that the flare load is 0 where SIL 3 is applied to the flare system. So it is beneficial to plant because the equipment investment cost can be saved if SIL3 is applied to the flare system. By this reason, so many plants in Korea applied SIL3 to the flare system, scrubber system and VCU, etc. For SIL3 application, the redundant shutdown valve with PST (partial stroke test) should be installed with 1 out of 2 voting and the positioner for PST function should have HART communication function. There were problems caused by HART communication devices, so the system design should be cautiously done considering the operation availability and safety at the same time.展开更多

With the differentiation of peasants' occupation and income differentiation, the functions of farmland also change accordingly. Based on the analysis of statistical data. the study found that over the past 30 years, the degree of occupational differentiation of peasants has become more and more complete, and income differentiation has also expanded. At the same time, the security function of traditional farmland is declining, but peasants pay more and more attention to the property function of farmland.展开更多

We also tested the model and proposed propositions by a sample evaluation method, specifically with 1 000 copies of questionnaires given out to managers or directors of MNEs’ subsidiaries in China Mainland and resulting in 151 sets of valid answers. The empirical study supports that national differences between the parent country and the host country and the strategies employed by MNEs do have impact on the subsidiary staffing, and MNE headquarters should make different staffing plans according to the difference of nations and strategies. We welcome testing our model by peer researchers in other country.展开更多

However, the convention is not enforced yet and the legal gaps found on limited existing regulations do not impose strict rules on the shipping industry and at the same time offer motives for the safe recycling of ships. Ship-owners seem reluctant to send their vessels for scrap but rather prefer to employ them till the last minute, preferably in areas where the environmentally-friendly concept is not of primary importance. The dynamics of this specialized industry can be better shown by examining variables such as legal instruments, occupational health and safety hazards, geographical allocation of scrapping sites, scrap prices, safety working plans and volume to be scrapped. The next step is to build a simulation model in order to discuss the relevant scenarios. The first scenario is based on the current conditions where the ship-owner's decision is mainly affected by the fluctuations of the market and whether the effectiveness of existing regulations can improve the working environment in terms of health and safety. The second scenario refers to the situation when the IMO Convention is implemented, then it will produce two major recycling markets, the first one for the convention ships and the second for non-convention ships.展开更多

In the last 30 years a variety of protective agents against UV exposure have been developed: physical filters, chemical filters and organic filters. Physical filters are the safest: they scatter and reflect UV rays, but are difficult to apply on the skin. Chemical filters are capable of absorbing these rays, they are cosmetically pleasant, but recent studies suggest a toxicological nature for some of these agents. Organic filters are the newest advance in sun products. Since 2003 the COLIPA Index [Europe] has regulated sun product availability on the market. In the USA, the FDA establishes the classification and the safety of sun products, which are considered topical medical drugs. This article summarizes the dermatologist's point of view, according to the patient's request, professional ethics and increasing offer of sun product.展开更多
