The interrelation between retention factors of several L-amino acids and their physico-chemical and structural properties can be determined in chromatographic research. In this paper we describe a predictor for retention factors with various properties of the L-amino acids. Eighteen L-amino acids are included in this study, and retention factors are measured experimentally by RP-HPLC. Binding energy ($E_b$), hydrophobicity (log P), molecular refractivity (MR), polarizability (${\alpha}$), total energy ($E_t$), water solubility (log S), connectivity index (${\chi}$) of different orders and Wiener index (w) are theoretically calculated. Relationships between these properties and retention factors are established, and their predictive and interpretive ability are evaluated. The equation of the relationship between retention factors and various descriptors of L-amino acids is suggested as linear and multiple linear form, and the correlation coefficients estimated are relatively higher than 0.90.

Objectives: This study aimed to identify the level of occupational and organizational retention intention and related factors among new dental hygienists. Methods: The participants were 195 dental hygienists employed for less than 24 months. A t-test and one-way analysis of variance were conducted to determine the level of intention to stay according to an individual's major-related characteristics and work environment awareness level. Pearson's correlation analysis was performed for each item, and stepwise multiple regression was performed for factors related to retention intention. Results: In the work environment, the organizational support network had the highest occupational retention intention (β=0.513). Organizational retention intention (β=0.351), working infrastructure (β=0.293), cooperation relationship (β=0.165), and management justice (β=0.151) were factors related to organizational retention intention (p<0.001). Employment at the practice hospital was related to occupational (β=0.167) and organizational retention intention (β=0.138), and satisfaction with clinical practice was related to occupational retention intention (β=0.327). Conclusions: New dental hygienists are expected to be actively utilized for long-term tenure in both occupations and organizations by actively reflecting on the results obtained through this study in the curriculum and working environment of dental hygienists.

Relationship marketing research has traditionally focused on the relationship among customer satisfaction, trust, and customer commitment, while assuming that the causal relationship of customer $satisfaction{\rightarrow}trust{\rightarrow}commitment$ is well understand. However, recently many scholars argue that customer satisfaction, trust, commitment can not explain long-term orientation fully, and suggest the need for more extensive researches investigating the determinants of long-term relational retention. The purpose of this study was to explained the relationship development process through the mediation effect of contact intensity and relationship termination cost between customer satisfaction and trust, and between trust and commitment, and an analysis the causal relationship among these variables. The results were as follows. First, the customer satisfaction had both direct and indirect effects on trust mediated by contact intensity. Second, the trust had both direct and indirect effects on commitment mediated by relationship termination cost. Third, the commitment influenced long-term orientation. Finally, the empirical results confirmed that the model add to the concept of mediation with contact intensity and relationship termination cost plays a strong, central role in explaining relationship development process between customer and fashion retail stores.

Despite their social mission, social enterprises work in the changing global economic environment and therefore face to comply with performance objectives. This situation means that human resources management strategy has a crucial role to play. Especially, the challenge in maintaining competitive efficiency depends on achieving a lower level of employee turnover. This study aims to investigate the role of job insecurity, job satisfaction, relationship with customers regarding the intention of retention among social enterprise workers. Data were collected in South Korea from 271 women employees in 36 social enterprises and the binomial logistic regression was used to assess the model hypothesized. As the result, social enterprise employees showed a considerably positive attitude toward the intent to stay their workplace. However, job insecurity appeared to have the strongest negative effect on the intention of retention, whereas job satisfaction and relationship with customers had the positive effects, above and beyond demographic variables and organization variables. The result suggested the human resource management can play a significant role in retaining social enterprise employees by reducing job instability and improving job satisfaction and customers management.

Objectives: The purpose of this study was to examine factors affecting the retention intention of clinical dental hygienists. Methods: A total of 190 clinical dental hygienists were recruited as participants. Data were collected from March to May, 2023 and then analyzed using t-test, ANOVA, Pearson's correlation coefficient, and multiple regression through PASW Statistics 26.0. Results: Mean scores for job crafting, job satisfaction, positive psychological capital and retention intention were 3.22, 3.46, 3.57 and 3.46 respectively. Retention intention showed a significant relationship with positive psychological capital (r=0.299), job crafting (r=0.214), and job satisfaction (r=0.649). The results of the multiple regression analysis indicated that job satisfaction was the strongest predictor of retention intention, explaining 24.1% of the total variance (F=4.550, p<0.001). Conclusions: Variables that can affect the retention intention of clinical dental hygienists were identified, with job satisfaction emerging as a significant factor affect retention intention.

This study investigates determinants of talent retention in textile and garment companies located in Vietnam's Binh Duong province to propose feasible actions for their sustainable development in the current context of competition on the labor market. This study uses self-completed questionnaires to collect data which are then analysed with statistical methods including scale reliability, exploratory factor analysis, and multiple linear regression. Specifically, results from an official survey of 129 people who are regarded as talents in related companies show that there are ten determinants, ranked in descending order of their importance, including: working environment; training and promotion opportunities; salary and benefits; personal loyalty; relationship with colleagues; nature of work; organizational recognition; type of ownership; relationship with superiors; and working experience. Moreover, it is also found that foreign companies are better in retaining their talents than private domestic ones. These findings suggest that, depending on their available resources, organizations need to focus on some of these factors to improve their talent retention; among them, it is critical to provide creative space or create conductive working environment by providing talents with proper tools and equipment for them to feel excited with their work and get things done in an optimal, efficient and effective manner.
