Background: The aim of this study was to analyze the public demand for information about the job of dental hygienists by mining text data collected from the online Q & A section on an Internet portal site. Methods: Text data were collected from inquiries that were posted on the Naver Q & A section from January 2003 to July 2020 using "dental hygienist job recognition," "role recognition," "medical assistance," and "scaling" as search keywords. Text mining techniques were used to identify significant Korean words and their frequency of occurrence. In addition, the association between words was analyzed. Results: A total of 10,753 Korean words related to the job of dental hygienists were extracted from the text data. "Chi-lyo (treatment)," "chigwa (dental clinic)," "ske-illing (scaling)," "itmom (gum)," and "chia (tooth)" were the five most frequently used words. The words were classified into the following areas of job of the dental hygienist: periodontal disease treatment and prevention, medical assistance, patient care and consultation, and others. Among these areas, the number of words related to medical assistance was the largest, with sixty-six association rules found between the words, and "chi-lyo," "chigwa," and "ske-illing" as core words. Conclusion: The public demand for information about the job of dental hygienists was mainly related to "chi-lyo," "chigwa," and "ske-illing" as core words, demonstrating that scaling is recognized by the public as the job of a dental hygienist. However, the high demand for information related to treatment and medical assistance in the context of dental hygienists indicates that the job of dental hygienists is recognized by the public as being more focused on medical assistance than preventive dental care that are provided with job autonomy.

Purpose: This study aims to make suggestions for the implementation of the job-based dental technician practical exam. Methods: The duties of dental technicians and the recent trends in the dental technician field were defined and identified, respectively, to achieve the purpose of the current study. The practical test system of domestic and foreign national tests was comparatively analyzed to seek improvements. Additionally, the direction of the practical test to be taken in the future was investigated through a public hearing of domestic experts. Results: As a result of this study, the job site of dental technicians was recently found to be undergoing many changes, and it can be observed that related laws and the work site have already changed. Comparison of overseas test systems showed that Korea was limited to a rather small evaluation range; in general, the scope of the evaluation of the practical tests in foreign countries was widely conducted. In the results of the public hearing, opinions exist that the evaluation range of the practical test was expanded and that new subjects were needed, but the opinion on the existence of practical difficulties was mainly mentioned. Conclusion: The evaluation range of the current practical examination subjects should be expanded and the evaluation of digital dental engineering subjects should be added to proceed with the job-based practical examination. However, it seems that efforts should be made gradually through various efforts in the future due to practical difficulties.

Concerning to Taeku city subway construction project(1-4 site), the original design was adapted NATM Tunnel method to the 8 meter thickness of overburden. Surveyor checked sity and design material and finally decided to change into Open Cut method because overburden is not only below 1 1/2 times thickness of comparate Tunnel width but there is no traffic conjunction in job site.

This paper presents a computational method that identifies an exact set of optimal overlap rates between critical activities to meet job site specific needs by using rework cost-slope. The procedures to compute the exact solution are provided in peudocode algorithm. The method is coded into Exact Concurrent Construction Scheduling system that allows practitioners to make more informed decision in accordance with the site-specific condition involved in the overlapping of critical activities. Test cases verify the validity of the computational method and the usability of the system.

The purpose of this study is to investigate the determinants of the occupational commitment of dental hygienists in Korea. The independent variables contain three groups of work rewards variables which consist of task reward variables (autonomy, job significance, resource adequacy, role conflict, workload, and routinization), social reward variables(supervisory support, co-worker support, and negative affectivity), and organizational reward variables(job security and promotional chances), and eight sociodemographic variables. The sample of this study consisted of 474 dental hygienists who work at general hospitals, university hospitals, dental hospitals and clinics across the nation. Data were collected with self-administered questionnaires and analyzed using hierarchical regression technique. It was found that: (1) job significance have a significant positive effect on the occupational commitment of dental hygienists; (2) role conflict, workload, routinization, and type of work site have significant negative effect on the occupational commitment of dental hygienists; (3) the study model explains 23.7% of the variance in occupational commitment among dental hygienists. The results of the study indicate that managers of dental clinics and hospitals should make efforts to extend the scope and quality of dental hygienists' work through job enlargement and job enrichment.

Industrial accidents and the resulting worker injuries have adverse effect on industry. From a financial perspective, these effects are realized in large sums of money, perhaps 1.5 billions of wons which are spent last year. In the past. industry in general was not aware of the high costs incurred through injuries to workers. However, this trend has changed in recent years. This paper shows that middle managers have a critical job with respect to safety in workers. The safer middle managers have better resulting than unsafe ones. This is because the workers are more efficient and productive when acting safely. Consequently, this study was primarily an attempt to identify the relationship among middle manager behavior, job site policies, and interpersonal relationships on the job as the affect work safety and performance. More specifically this study focused on the investigation of the research questions by testing the hypotheses.

The aim of this study is to survey and analyze the safety perception and attitude of the construction managers for the purpose of contributing to the construction industry accident prevention by inducing safety behaviors of managers. The data analysis found that there were significant differences on safety perception and attitude depending on job positions. This survey found that job position and career affect the safety perception and attitude of manager. Further analysis revealed job position has more an effect on it than career. Therefore, in order to improve the safety perception and attitude of managers, it is effective to put managers more responsibility on safety.

Purpose: Job satisfaction, spouse support, parenting stress, and the factors that influence parenting stress in female fire fighters with preschool-aged children were examined. Methods: Data were collected from 180 female fire fighters who worked at the fire station from June to July 2013 and had preschool-aged children. Data were analyzed using SPSS WIN 21.0. Results: Average job satisfaction was 2.81, spouse support was 3.54, and parenting stress was 3.61. Parenting stress was negatively correlated with spouse support and job satisfaction. Job satisfaction and spouse support were positively correlated. Factors influencing parenting stress included employment period (${\beta}$=0.093, p <.05), a husband who is not a fire fighter (${\beta}$=-8.971, p <.05), having three children (${\beta}$=27.395, p <.05), delegating childcare to relatives (${\beta}$=9.605, p <.05), income (${\beta}$=-0.920, p <.05), and spouse support (${\beta}$=-0.589, p <.05). Conclusion: To reduce parenting stress and increase job satisfaction, female fire fighters with preschool-aged children should be assigned to stable administrative work instead of stressful on-site work. Husbands who are fire fighters should take advantage of paternity leave, implemented by the Ministry of Public Safety and Security, to increase their active participation in parenting.
