This study systematically collected and analyzed the results of previous studies on job satisfaction of dental hygienists and analyzed the job satisfaction measurement tools and related factors. It was conducted according to the systematic review guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis), and 44 articles were used in the final analysis. In order to measure job satisfaction, ten measuring tools were used. All the measuring tool were developed overseas and they were modified. As a result of the literature analysis, the higher the job satisfaction, the more negative correlation was found between turnover intention and job stress, and positive correlation was found between organizational commitment and professional occupation. The purpose of this study is to analyze the relationship between job satisfaction and various variables and to investigate the improvement of job satisfaction of dental hygienist based on the results of this study.

This paper provides empirical evidence on the impact of increasing import penetration on the job stability of Korean workers. The main results are as follows. First, import penetration negatively affects job stability. If an industry's ratio of imports to total supply increases by 1 percentage point, the turnover probability of workers in that industry increases by 4.5 percentage points. Second, the effect of trade liberalization is not symmetric between imports and exports. Unlike the case of imports, an industry's ratio of exports to output does not have a significant effect on job stability. Third, the impact of import penetration is not uniform across different types of workers. The negative impact is greater for workers in small firms, less educated workers, and those not protected by labor unions.

The present study aimed to examine the relationship between person-job fit, work meaningfulness, job involvement, and career satisfaction, which have recently gained attention from employees and HR professionals. Based on previous studies, we logically established a path from person-job fit to work meaningfulness, job involvement, and ultimately career satisfaction. This study sought to validate these dual mediating effect. A survey was conducted with 283 employees, and the data were analyzed using SPSS 21 and Process Macro. The main findings of the study are as follows: person-job fit, work meaningfulness, job involvement, and career satisfaction showed positive correlations. The dual mediating effects of work meaningfulness and job involvement on the relationship between person-job fit and career satisfaction were statistically significant. These results imply that in order to prevent employee turnover and ensure the organization's sustained performance, it is necessary to design jobs in a way that allows employees to perceive their work as suitable and aligned with their characteristics, thereby enhancing positive psychological factors such as work meaningfulness, job involvement, and career satisfaction. The conclusions provide implications, limitations, and suggestions for future research.

The few lignin biomarker studies conducted in tropical environments are hampered by having to use references signatures established for plants and soils characteristic of the temperate zone. This study presents a lignin biomarker analysis (vanillyls (V), p-hydroxyls (P), syringyls (S), cinnamyls (C)) of the dominant plant species and soil horizons as well as an analysis of the interrelated terrigenous organic matter (TOM) dynamics between vegetation and soil of the $Tapaj{\acute{o}}s$ river region, an active colonization front in the Brazilian Amazon. We collected and analyzed samples from 17 fresh dominant plant species and 48 soil cores at three depths (0-5 cm, 20-25 cm, 50-55 cm) from primary rainforest, fallow forest, subsistence agriculture fields and pastures. Lignin signatures in tropical plants clearly distinguish from temperate ones with high ratios of Acid/aldehyde of vanillyls ((Ad/Al)v) and P/V+S. Contrary to temperate environments, similarly high ratios in tropical soils are not related to TOM degradation along with pedogenesis but to direct influence of plants growing on them. Lignin signatures of both plants and soils of primary rainforest and fallow forest clearly distinguish from those of non-forested areas, i.e., agriculture fields and pastures. Attalea speciosa Palm trees, an invasive species in all perturbed landscapes of the Amazon, exhibit lignin signatures clearly distinct from other dominant plant species. The study of lignin signatures in tropical areas thus represents a powerful tool to evaluate the impact of primary rainforest clearing on TOM dynamics in tropical areas.

Purpose: This study was conducted to examine activities of daily living (ADL) of older adults admitted to Korean long-term care hospitals (LTCHs), and to explore the patient and organizational factors that have an impact on the ADL of this population. Methods: A secondary analysis of the Korean minimum data set (K-MDS) of patients (N=14,369) and of the profiles of LTCHs (N=358) from the Health Insurance Review and Assessment Service was done between January and July 2008. The outcome variable was ADL score 6 months after baseline assessment. Multi-level linear regression was employed to explore the patient and organizational factors that affected ADL scores. Results: Of the patients, 45.4% had a baseline ADL score of between 31 and 40, with a score of 40 indicating that the patient was entirely dependent for all items. None of the organizational characteristics were significantly associated with effects on the ADLs of older adults who had been in a LTHC for at least 6 months. However, patient characteristics, such as age, baseline ADL, frequency of physical therapy, urinary incontinence, fecal incontinence, pressure ulcers, and having a tube or catheter, were significantly associated with ADL 6 months after baseline. Conclusion: In order to maintain and improve the ADL of older adults in LTCHs, we should develop strategies to prevent urinary and fecal incontinence, pressure ulcers, unnecessary tubes or catheters, providing adequate physical therapy. Additional studies should include more detailed information regarding nursing staff, including RN hours for direct care, education level and turnover.

Comparative study of the biomass productioin and the cyclings of nitrogen, phosphorus and potassium was carried out on the east and the northwest facing slope in the montane grassland of Mt. Soback. The maximum productin during the growing season in the east and the northwest slope were 1, 150g/m2.yr, and 755g/m2.yr. in the August, respectively. The positive correlation was appearent between biomass production and A-layer depth of the soil and the correlation coefficient (r=.964) was very significant at 1% level. In the above ground materials, the nutrients contents were high at the early of the growing season but decreased gradually. In roots, however, there are no significant trend throughout the growing season. Total amounts of minerals uptaken by plants during the growing season in the east and the northwest site were 18.20 and 10.66g/m2.yr for N, 0.06 and 0.03g/m2.yr for P, 0.23 and 0.11g/m2.yr for K, respectively. the minerals returned to the soil by litter decomposition and roots decay in the east and the northwest site were 16.19 and 9.62g/m2.yr for N, 0.046 and 0.021g/m2.yr for P, 0.211 and 0.099g/m2.yr for K, respectively. The turnover the rate (absorbed/returned) of the nutrients in the east and the northwest site were 1.13 and 1.14 for N, 1.30 and 1.43 for P, 1.09 and 1.11 for K, and the absorption rates of minerals were 0.39 and 0.29% for N, 3.16 and 1.88% for P, 0.91 and 0.57% for K, respectively.

The results of this study showed that victim's job motivation, organizational distrust, nervousness, turnover intention, frustration, stress and resistance, powerlessness and alienation were similar to previous studies. I was overwhelmed by the negative force of the collective union and experienced anger in the reality that one individual could not resist or find a solution. In addition, psychological factors such as union members' fear of union bullying were found to have a positive effect on the union members who did not join the strike and those who did not join the strike. It is necessary to consider the question of whether the group bullying behavior is valid in that the union bullying behavior of the union is effective in achieving the purpose of the group.

The purpose of this study is to provide policy implications on the settlement of regional labor market of young women through detailed study on the experience of regional labor market in Jeollanam-do Province. For this purpose, this study analyzed the labor mobility experience in the regional labor market of young women, which lacked specific case studies. In this study, we have identified the causes of job changes by dividing the labor mobility of young women into intra-career moves and inter-career moves. For the causes of labor mobility we divided into two aspects: problems in preparation for employment and employment conditions. The inter-career moves included more diverse factors than intra-career moves. In the inter-career moves, problems in preparation for employment were highlighted as the causes of job changes. In the case of moving within the career, young women would leave because of the employment conditions such as the expiration of the employment period, but the turnover appears to be the way of retaining their previous career. On the other hand, in the case of intra-career moves, the strong desire to maintain the career was shown, and at the same time, the possibility of leaving the region was also high. Based on the case study, this study proposed systematic career counseling for career match, and construction of career management system to support continuous career development.

Purpose: The aim of this study was to investigate and identify work environment, job embeddedness, and burnout among general hospital nurses in Korea. Methods: The participants were 563 clinical nurses working in 13 general hospitals across the country. Data were analyzed using SPSS and Microsoft Excel programs. Results: Mean scores were 2.62 for nurses' work environment, 2.97 for job embeddedness, and 3.61 for burnout. Nurses' work environment showed a positive correlation with job embeddedness (r=.70, p<.001), but a negative correlation with burnout (r=-.49, p<.001). Subcategories of nurses' work environment that predicted job embeddedness included satisfaction and happiness, hospital support for the work environment, patient care environment, satisfaction with work schedule, manager leadership, supportive environment for nurses' work, and computer problems. Subcategories of nurses' work environment that predicted burnout included satisfaction and happiness, violence within ward, hospital support for work environment, and patient care environment. Conclusion: Findings from this study indicate the need to evaluate and improve the work environment for nurses to increase job embeddedness and control burnout. Future studies should explore ways in which turnover intention can be decreased by changing nurses' work environment.

Professions with librarianship can be found in various fields. It includes all different kinds of libraries, including academic, public, special, and school libraries. Moreover, there are national and commercial information distribution bodies, and other bodies supporting the national body such as library automation companies, library supply companies, and library outsourcing companies. Careers of those who have studied in library and information science could be developed in all these fields. High flexibility and labour turnover can be expected due to the wide range of career fields. Nevertheless, there have been very little studies reflecting the reasons of high level of turnovers and flexibility in librarian workforce. Therefore, this paper invastigates career movement and development of librarian as a foundation stone of further researches. It also analyzes career development process of librarians, including career paths of those working in libraries and other related areas, their efforts for career development, factors influencing their career movements.
