Objectives: The objectives of this study were to find the influential factors of dental hygienists' work environment and level of perception of rights on their retention intention, and to provide basic data for protecting their rights and interests and improving their employment rate. Methods: From June 6 to July 24, 2021, a questionnaire survey was conducted among 214 dental hygienists via an online link. After questionnaire collection, IBM SPSS program (ver. 21.0; IBM Corp., Armonk, NY, USA) was used to conduct frequency analysis, t-test, one-way ANOVA and multiple regression analysis. Results: The significant and positive influential factors of dental hygienists' retention intention were married individuals (p=0.022), fewer working hours (p<0.001, p=0.007), good work environment (p=0.002), higher wages (p<0.001, p<0.001), higher education (p=0.032), and perception of rights in a mid-level (p=0.038). Conclusions: It is necessary to consider wages and welfare equivalent to dental hygienists' work intensity and workload. By regularly educating dental hygienists to increase their perception of rights, expanding an opportunity of participation, and improving their work environment, it will be possible to increase their retention intention and efficiently establish manpower in dental clinics.
Objective: Autophagy is highly active in ovariectomized mice experiencing hormone deprivation, especially in the uterine mesenchyme. Autophagy is responsible for the turnover of vasoactive factors in the uterus, which was demonstrated in anti-Müllerian hormone receptor type 2 receptor (Amhr2)-Cre-driven autophagy-related gene 7 (Atg7) knockout (Amhr-Cre/Atg7f/f mice). In that study, we uncovered a striking difference in the amount of sequestosome 1 (SQSTM1) accumulation between virgin mice and breeder mice with the same genotype. Herein, we aimed to determine whether repeated breeding changed the composition of mesenchymal cell populations in the uterine stroma. Methods: All female mice used in this study were of the same genotype. Atg7 was deleted by Amhr2 promoter-driven Cre recombinase in the uterine stroma and myometrium, except for a triangular stromal region on the mesometrial side. Amhr-Cre/Atg7f/f female mice were divided into two groups: virgin mice with no mating history and aged between 11 and 12 months, and breeder mice with at least 6-month breeding cycles with multiple pregnancies and aged around 12 months. The uteri were used for Western blotting and immunofluorescence staining. Results: SQSTM1 accumulation, representing Atg7 deletion and halted autophagy, was much higher in virgin mice than in breeders. Breeders showed reduced accumulation of several vasoconstrictive factors, which are potential autophagy targets, in the uterus, suggesting that the uterine stroma was repopulated with autophagy-intact cells during repeated pregnancies. Conclusion: Multiple pregnancies seem to have improved the uterine environment by replacing autophagy-deficient cells with autophagy-intact cells, providing evidence of cell mixing.
The Jido Pond system was investigated from April, 1979 through March, 1980, in respect of seasonal changes in physico-chemical factors: i.e., temperature, pH, DO, BOD, COD, $Cl^-, \; Mg^{++}$, alkalinity, detergent, $SiO_2, PO_4\;^{3-}, NH_4\;^+, NO_2\;^-, NO_3\;^-$, total N, OM and OC; phytoplankton community growth; and the ecosystem metabolism. The phytoplankton community was represented by 23 species belonging to Chlorophyta, Bacillariophyta and Cyanophyta; each sharing 11, 9 3 respectively. The Chlorophyceans dominated the phytoplankton community contributing 75% of the total ?미 counts. The ranges of biotic diversity indices were, d, 0.85~2.80; H, 1.10~2.40; c, 0.13~0/40; and 3, 0.56~0.90. The chlorophyll standing crop varied in between 0.043 and 0.385g/$\textrm{cm}^2$ surface area. The ranges of photosynthetic and respiratory rates were 0.36~4.50; and 0.10~1.40 $O_2$ mg/1/hr, respectively. The monthly areal net primary production varied from 23.9 to 305.1C g/$\textrm{m}^2$/month. The Eu of the net production seasonally varied in between 0.31 and 7.80%, and the annual mean was 2.44%. The annual turnover times of phosphorus and nitrogen were 20 and 3 days, respectively.
Objectives : This study is to make basic materials for an effective human resource management plan by understanding relationship between self-esteem and intention of transfer of dental hygienists who are working in dental diagnostic institutions and to contribute to human resource program development for promoting development into a dental hygienic profession. Methods : This survey was carried out for dental hygienists who are engaging in dental diagnostic institutions in part of Cheonbuk Area by survey researchers for 10 days from September 14 to September 24, 2011 by visiting dental clinics after respondents replied to a questionnaire after listening to explanations of study purposes. Total 210 copies of questionnaire were retrieved and 201 copies were used as materials for the final analysis excluding 9 copies with insincere replies. Results : 1. The total average grade for self-esteem of study objects was 32.83(${\pm}3.08$) points. The total average of intention of transfer was found to be 32.91(${\pm}7.50$) points. 2. Self-esteem by satisfaction on the current workplaces was shown to be high with 'very satisfactory'(p=0.028), which has significant difference statistically (p<0.05). 3. In the intention of transfer by general characteristics, 20-25 years ($35.15{\pm}7.17$) was higher than over 40 years old ($23.44{\pm}3.47$) by age to show significant difference statistically (p=0.000). As for married status, single ($34.42{\pm}6.64$) was found to have higher intention of transfer than married ($30.28{\pm}8.11$), which showed significant difference statistically (p=0.018). As for the education background, 3 year course college graduates ($33.49{\pm}7.25$) showed more intention of transfer than over undergraduate students ($22.75{\pm}9.43$) to show significance statistically (p=0.002) and in the working years 1~3 years ($34.40{\pm}7.07$) was found to have more intention of transfer than over 10 years ($25.13{\pm}5.08$) to be significant statistically (p=0.000). The annual income less than 25 million won ($34.10{\pm}6.54$) showed more intention of transfer than over 40 million won ($21.00{\pm}0.00$) (p=0.000). 4. Intention of transfer by satisfaction of current workplaces was found to be high in 'very unsatisfactory', which showed significant difference statistically (p<0.001). 5. Pure correlation between self-esteem and intention of transfer came into existence and intention of transfer was found to be higher as self-esteem is higher. Conclusions : Through results as above, intention of transfer of dental hygienists was found to be higher as self-esteem is higher. Various follow-up studies which are to perform empirical verification by analyzing various factors which can affect intention of transfer based on this and using them as control variables are thought to be tried.

The purpose of this study is to investigate the effect of job experience while attending college on the turnover risk in the first job following graduation. Data was obtained from the 2015 Graduates Occupational Mobility Survey (GOMS). Subjects included college graduates under 30 years of age, who graduated from high school and entered college in the same year. The results of this study are as follows: First, students who had job experience while attending school were relatively low in economic characteristics, but showed active employment preparation behavior. Second, there was a significant difference in the characteristics of entry into the labor market according to whether they had job experience while attending school. It was found that the securing their first job of graduates with job experience was shorter, and the period of tenure was longer, but their wage was smaller than non-experienced graduates. Third, the Cox regression analysis confirmed what factors affected their employment period, and that job experience, experience frequency, and experience period while attending school had a positive effect on lowering turnover risk. Therefore, this study found that job experience during schooling years makes the employment period of the job longer after graduation, which is consistent with those who had previous job experience. However, the greater amount of job experience during the period of study positively affects job retention.
In this study, parallel work-learning training, which was started in 2013 as a pre-employment promotion policy, is an important factor that determines the success or failure of training. As a time when various institutional supplementation is needed to encourage company participation, this study is to identify the factors of participation of companies participating in work-learning parallel. To this end, a questionnaire survey was conducted of companies participating in parallel work-learning in Chungnam, and the results were analyzed using the structural equation model. As a result of the study, the reason for the company's participation in parallel work-learning was firstly, 84% of government subsidy received education and training expenses. Second, 66% of workers were able to pay less than regular workers, and thirdly, it was easy to hire new employees in the field. 26%, 17% of them were invited by acquaintances for no particular reason. Therefore, the study suggests that participation in the work-learning parallel training contributes to the management costs, management of employee turnover, and human resource development. In future research, it is necessary to subdivide tests and estimates by conducting studies on regions, occupations, gender, wages, and years of service in Korea.
The purpose of this convergence study is to confirm the effects of nurses' coaching behavior level and emotional intelligence on organizational effectiveness. Subjects of study were 182 nurse in four general hospitals and they answer self-report questionnaire between March 2nd to March twenty three 2017. and date analyzed using the SPSS/WIN 21.0 program. As a result, coaching behavior level $3.28{\pm}0.42point$, Emotional Intelligence $3.27{\pm}0.45point$ and Organizational commitment $2.89{\pm}0.52point$, Job satisfaction $2.94{\pm}0.53point$, Turnover intention $3.24{\pm}0.56point$ among organizational effectiveness. Organizational commitment was positively correlated with coaching behavior level and emotional intelligence, significantly affecting Convergence Factors on organizational effectiveness were analysed into Experience preceptor(${\beta}=.25$, p=.001), Nursing satisfaction(${\beta}=.26$, p<.001), Coaching behavior level(${\beta}=.26$, p<.001) and the explanation ability was 25%. In order to enhance organizational commitment of nurse, the characteristics of the job is satisfied and if there is an intervention program that improve the level of coaching behavior, it is expected the effectiveness of the organization will be enhanced.

In the digital transformation paradigm, IT employee work as a key human resource to accept new technologies and to lead their organization to be settled them efficiently. However, due to relatively short term of their job life and high turnover rate, the companies and the organizations are still experiencing problem the lack of IT manpower or turnover. In this study, it attempted to analyze the relationship between IT employee's technostress factors such as techno-overload, techno-complexity, techno-uncertainty, techno-invasion, and techno-insecurity and job burnout through stress coping. To reveal the structural relationship between main variables, the survey was conducted on 318 IT employees. An EFA, CFA, and reliability analysis were performed to confirm reliability and validity, and the structural equation model was conducted to testify research hypotheses. The main results are as follows. First, it was found that techno-uncertainty and techno-insecurity had the significant positive effect on problem focused coping(PFC). And, techno-complexity, techno-uncertainty, and techno-insecurity were found to have a significant positive effect on emotion focused coping(EFC). Second, in the relationship between stress coping and job burnout, it was found that EFC had a significant positive effect on burnout. Third, in the relationship between technostress and burnout, techno-uncertainty and techno-invasion were found to have a significant positive effect on burnout. In addition, it was found that the mediator effect of stress coping between techno-overload and techno-complexity through EFC. Therefore, these outputs are expected to suggest how to motivate IT employees who work as key role in efficient management on IT assets and strengthen competitiveness in digital transformation paradigm.
A number of companies are considering for merger and acquisition (M&A) as one of business strategies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&A, often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies conducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to integration of IS organizations or physical information systems. In order to conduct a comprehensive research on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on comparative case studies.
The purpose of this study was to identify the factors affecting job satisfaction in dental hygienists with and without schoolwork, who form professional manpower in dental clinics, and provide basic data that could help develop detailed plans for reducing the turnover intention and improving job satisfaction. For data collection, convenience sampling was performed among clinical dental hygienists at dental clinics in Daejeon and Chungcheong and Gyeongsang Provinces from July 20 to September 20, 2019, and a self-administered questionnaire was used and the data were analyzed by T-test, One-way Anova, Pearson correlation, Stepwise multiple regression analysis, etc. using IBM SPSS/WIN 20.0. For the dental hygienists with schoolwork, job stress was negatively correlated with professional self-concept and job satisfaction, and professional self-concept was positively correlated with job satisfaction; for the dental hygienists without schoolwork, job stress was negatively correlated with professional self-concept and job satisfaction, and professional self-concept was positively correlated with job satisfaction. The factors affecting job satisfaction were professional self-concept, job stress, and age of ≥30 for the dental hygienists with schoolwork and professional self-concept, job stress, and the position as a middle manager for those without schoolwork. To put these results together, professional self-concept and job stress were factors affecting job satisfaction for dental hygienists with and without schoolwork. It is necessary to focus on the formation of good dental organizational culture through positive institutional support as well as through systematic establishment of professional self-concept.
