The purpose of the rules on the Occupational Safety and Health Standards (hereafter safety and health rules) is to regulate the safety and health measures stipulated in the Occupational Safety and Health Act and the specific instructions necessary for their implementation. However, the safety and health rules are extensive and complexly connected, making navigation difficult for users. In order for users to readily access safety and health rules, this study analyzed the frequency, distribution, and significance of terms included in the overall rules. First, the term distribution index was created based on the frequency and distribution of words extracted through text mining. The term distribution index derives from whether a word appears only in a specific chapter or across all rules. This allows users to effectively explore terms to be followed in a specific working environment and terms to be complied with in the overall working environment. Next, the related words of the previously derived terms were visualized through t-SNE and the Word2Vec algorithm. This can help prioritize the things that need to be managed first, focusing on key terms without checking the overall rules. Moreover, this study can help users explore safety and health rules by allowing them to understand the distribution of words and visualize related terms.

Background: In the mining industry, various methods of accident analysis have utilized official accident investigations to try and establish broader causation mechanisms. An emerging area of interest is identifying the extent to which cultural influences, such as safety culture, are acting as drivers in the reoccurrence of accidents. Thus, the overall objective of this study was to analyze occupational health and safety (OHS) reports in mining to investigate if/how safety culture has historically been framed in the mining industry, as it relates to accident causation. Methods: Using a computer-assisted qualitative data analysis software, 34 definitions of safety culture were analyzed to highlight key terms. Based on word count and contextual relevance, 26 key terms were captured. Ten OHS reports were then analyzed via an inductive thematic analysis, using the key terms. This analysis provided a concept map representing the 50-year data set and facilitated the use of text framing to highlight safety culture in the selected OHS mining reports. Results: Overall, 954 references and six themes, safety culture, attitude, competence, belief, patterns, and norms, were identified in the data set. Of the 26 key terms originally identified, 24 of them were captured within the text. The results made evident two distinct frames in which to interpret the data: the role of the individual and the role of the organization, in safety culture. Conclusion: Unless efforts are made to understand and alter cultural drivers and share these findings within and across industries, the same accidents are likely to continue to occur.

This paper examines the protective clothing satisfaction rate of riot policemen. The protective clothing currently in use is the version that underwent enhancement and was distributed in 2009. This version underwent significant enhancements compared to the protective clothing introduced in 1996 in terms of safety and body fitness; however, there is room for further enhancement in terms of activity, thermal comfort and easiness. In this research, a questionnaire survey was conducted on 386 riot policemen working at the Seoul Riot Police Station to study their use of protective clothing and satisfaction rate. The survey questions included safety, activity and body fitness in terms of functionality and comfort as well as easiness and design in terms of wearing comfort. Activity scored the lowest (2.89) in terms of functionality as well as comfort (2.40) that scored the lowest in terms of wearing comfort. It is concluded that, in order to correct deficiencies, the weight of protective clothing must be reduced and design changes must be made to eliminate unnecessary areas in clothing and facilitate faster dressing/undressing. In addition, it is strongly recommended that shock absorption materials be inserted only in vital areas in order to enhance thermal comfort.

As one of the useful approaches to enhance safety managers' competencies, this study aims to suggest improvement plans in terms of education in school and on the job for safety managers. Educational needs at schools and job training institutes were surveyed with 321 safety managers in Daejon & Chongju Area. Correspondence with university professors at safety engineering departments via email was also conducted. Collected data were put into the R stochastic program in codified form and quantitatively analyzed through two-dimensional cross-tabulations and a chi-square test. With respect to school education, three academic subjects were examined. Job training was suggested to be conducted as 'training for trainers', which should be more flexible in terms of contents, method, and fees. Periodical investigation of educational needs for safety personnel who are consumers of safety education and training was also proposed.

Background & Objectives : Korea is face with the social need for health care technology assessment so that it is urgently needed to found principles and methodology in technology assessment in health care. As a groundwork for health care technology assessment, we tried to prioritize medical technology for assessment. Among medical technologies, procedure is somewhat difficult to assess, compared to drug or equipment. In this study, we aimed at the prioritisation of medical procedure to be assessed, in terms of efficay, safety, and adequacy. Method : For the standardized classification of medical procedure, ICD-9-CM(International Classification of Diseases 9th edition - Clinical Modification) was used. Among the list the procedures coming under otorhinolaringjology and thoracic surgery were selected by three family physicians. The list of procedure was mailed to the board certified surgeons of both disciplines, with the question asking about the necessity for assessment in terms of efficay, safety, and adequacy. Replied questionnaires were analyzed in each procedure. Results : Of 560 otorhinolaryngologist and 480 thoracic surgeon, 114 surgeons replied. Of otorhinolaryngological procedure, incision, excision, and destruction of inner ear : fenestration of inner ear : stapedectomy and its revision were the most urgent technology to assess in the aspect of safety. For adequacy, operations on Eustachian tube: fenestration of inner ear: incision, excision, and destruction of inner ear were highly ranked in necessity, and for efficary, operations on Eustachian tube; external maxillary antrotomy; fenestration of inner ear. Thoracic surgeons replied thoracic procedures, lung transplantation; heart transplantation; implantation of heart assist system [pump] are most important for evaluation in terms of safety; and heart transplantation; Lung transplantation; Implantation of heart assist system [pump] in terms of adequacy, and surgical collapse of lung [Artificia니 pnemothorax or pnuexoperitoeum]; lung transplantation; periarterial sympathectomy in terms of efficacy. As a whole, surgeons regard safety evaluation is more urgent than adequacy or efficary. In addition, otorhinolaryngological surgeons regard evaluation of their procedures more urgent than thoracic surgeons regard theirs. Conclusion : By the questionnaire to board certified physicians, we get some preliminary data for prioritisation of technologies to assess. Through the questionnaire like this, much information would be gathered for technology assessment, especially for medical procedure, if not enough. In the near future, well structured expert opinion gathering research, such as modified Delphi or nominal group technique, should be done succeedingly.
