  • Since MTA has many beneficial properties such as biocompatibility, great sealing capacity, antibacterial effects, low cytotoxicity, and stimulation of formation of mineralized tissue, it has been widely used as the material of choice in root-end filling, apexification, pulpotomy, perforation repair and so on. However, despite its favorable characteristics, MTA presents working properties which are less than ideal. The resulting cement from the mixing of powder and water is difficult to manipulate, and its setting time has been reported to be 2 h 45 min whereas the working time is <4 minutes. Additional moisture is also required to activate the setting of the cement. Moreover, according to recent studies, the physical properties of MT A may be hampered by acidic environment or blood contamination. Therefore, practitioners may have surprisingly worse results than they expected when they are not fully acquainted with the characteristics and manipulation method of MTA.

  • The port, differently from general working places, is a closed area required for security, customs, and quarantine procedures. The loading and unloading is being done differently by ports, cargoes, and ships. To do loading and unloading, a lot of equipment and different types of labor are required, which flow is complicated and safe management is essential. As above mentioned the port is very unique and very deteriorated working place in its working environment. The purpose of this study is to propose ways to reduce and prevent from port accidents. As first step to do this, we have collected 923 accidents happened at Incheon Port during the period of 1994 to 2003. We have thoroughly analyzed characteristics, harmfulness, and risk of the loading/unloading they have done, as well as the accident frequency and relationship between the accidents. As second step to further analyze, We have employed DMAIC technology, an advanced process of 6 sigma presently in spotlight as the best program for management innovation. This analysis results in recognition of important accident characteristics, causes and effects analysis, critical causes of accident, and suggestions to decrease accidents.

  • Purpose: This study explored the association between workplace discrimination and violence and depressive symptoms among Korean employees. Methods: Data were obtained from the 4th Korean Working Condition Survey of 2014, which included 21,902 Korean employees. Depressive symptoms were measured using the WHO-5 Well-Being Index questionnaire scales. Results: A statistically significant relationship between workplace discrimination and workplace violence was found, and these two variables were also associated with depressive symptoms. After adjusting for variables such as sociodemographic characteristics, physical risk, and psychosocial working environment, workplace discrimination (OR=1.22, p<.001) and workplace violence (OR=1.69, p<.001) were both significantly associated with depressive symptoms. Conclusion: This study indicates that to promote employees' psychological health, systems and programs to prevent workplace discrimination and violence are needed. Development of these systems and programs should consider employees' experiences of workplace discrimination and workplace violence, sociodemographic characteristics, physical risk, and psychosocial working environments.

  • The purpose of this study was to analyze in-depth the nurses' experience of hospital work and the factors affecting career interruption of nurses. For this purpose, 20 inactive nurses aged 26-55 participated in interviews about their experience as nurses, characteristics of nursing work, and reasons for retirement, and applied the analysis method of Colaizzi among phenomenological research methods. The analysis resulted in 104 significant statements, 17 formulated meanings, 6 clusters of theme, and 2 categories. The two categories are nursing work characteristics and work environment characteristics. In the characteristics of nursing work, there are four clusters of theme of 'time pressure', 'lack of autonomy', 'physical and emotional labor', 'low wage increase', and in the characteristics of nursing work environment, there are two clusters of theme of 'physical environment' and 'human environment'. Therefore, in order to improve the nurse career interruption, efforts should be made to alleviate excessive work intensity, raise the appropriate level of pay and provide a safe working environment.

  • Objectives: This study aimed to investigate factors for retention intention among long-term employed dental hygienists and to provide basic data for improving the long-term service (working) environment. Methods: A total of 202 dental hygienists with more than five years' work experience at dental hospitals and clinics located in Seoul, Gwangju, and Jeonnam Province, South Korea, were surveyed. The data were analyzed for each factor using exploratory factor analysis, and differences according to the general characteristics of the participants were analyzed using an independent sample t-test, one-way ANOVA and a hierarchical multiple regression analysis. Results: At the current workplace, a better working environment, and higher job satisfaction were associated with higher retention intention. However, lower professionalism in dental hygiene as a subdomain of the professional self-concept domain was associated with higher retention intention. Conclusions: To increase retention intention among dental hygienists, it is necessary to improve the working environment in which dental hygienists can perform professional roles and seek ways to establish their identity as professionals in dental healthcare settings.
