Edible coatings are one of the most innovative methods to preserve the quality and increase the shelf life of fresh fruits and vegetables. A successful edible coating should have a barrier against gases, especially oxygen and water vapor, and have good surface characteristics. Today, chitosan coating is widely used due to its properties, such as non-toxic, biodegradable, and biocompatibility. Is. Coating the surface of fruits and vegetables with chitosan increases shelf life due to reducing weight loss and reducing respiration rate and also reduces decay due to its antimicrobial and anti-fungal effect. This work discusses the effect of using chitosan coating containing chamomile extract to increase fresh vegetables'shelf life. In addition to increasing the shelf life of vegetables, this method can be used as a solution for the economic management of human resources. The results of this method confirm the successful synthesis of these nanoparticles, and the results of applying this food coating on vegetables have been successful. They have increased the shelf life of vegetables such as basil and spinach.

Background: This study aimed to investigate the decline in quality of life (QOL) by examining changes in the employment status of workers who had completed medical treatment after an industrial accident. Methods: This study utilized the Panel Study of Worker's Compensation Insurance cohort (published in October 2020) containing a sample survey of 3,294 occupationally injured workers who completed medical care in 2017. We divided this population into four groups according to changes in working status. A multivariate logistic regression model was utilized for evaluating QOL decline by adjusting for the basic characteristics and working environment at the time of accident. Subgroup analysis evaluated whether QOL decline differed according to disability grade and industry group. Results: The QOL decline in the "maintained employment," "employed to unemployed," "remained unemployed," and "unemployed to employed" groups were 15.3%, 28.1%, 20.2%, and 11.9%, respectively. The "maintained employment" group provided a reference. As a result of adjusting for the socioeconomic status and working environment, the odds ratios (ORs) of QOL decline for the "employed to unemployed" group and the "remained unemployed" group were 2.13 (95% confidence interval [CI], 1.51-3.01) and 1.47 (95% CI, 1.13-1.90), respectively. The "unemployed to employed" group had a non-significant OR of 0.76 (95% CI, 0.54-1.07). Conclusions: This study revealed that continuous unemployment or unstable employment negatively affected industrially injured workers' QOL. Policy researchers and relevant ministries should further develop and improve "return to work" programs that could maintain decent employment avenues within the workers' compensation system.

Objectives: This work aimed to investigate differentiations of Korean medicine's pathological symptoms and SF-12 sub scales among normal, overweight and obese subjects from multi-center case report. Methods: From 2009 to 2011 survey were carried out to 1,589 subjects who took treatment or were hospitalized in 7 Korean medicine hospitals and 3 Korean medicine clinic. Survey include Korean medicine's pathological symptoms and SF-12. Whole survey were obtained from subjects with interviewers. Obesity degree was divided into three groups by body mass index: Normal group is from 18.5 below 23, overweight from 23 below 25 and obese group is over 25. Chi-square test was performed to reveal differentiation response rate of pathologic symptoms among obesity groups. ANOVA test was carried out for compare each group's SF-12 sub scales. Results: Patients of overweight or obesity have more symptoms such as skin itching, swelling, weakness in lower legs, and feverish with swollen joints. Contrary, normal weight group responded symptoms of dry skin more than those of obese group. As a fatigue, obese group have more fatigue feeling at afternoon and evening, compared to high frequency response of normal weight groups' morning fatigue. Obese groups shows low physical scores of health related quality of life, in contrast, high mental scores of that. Conclusions: This is first work of pathologic symptoms shown by obese groups. This would contribute to standardization of Korean medicine's pattern identification as suggestion of classification point for obese groups.

Purpose: The aims of this study were to examine the work, client, and personal environments of community health practitioners, including the level of their professional quality of life (ProQOL), and identify the factors affecting their ProQOL. Methods: Data were collected using a web-survey questionnaire, which was completed by a sample of 308 community health practitioners currently working in Korea. The questionnaire included items on ProQOL; three dimensions labeled compassion satisfaction, burn out, and secondary traumatic stress; job stress; job satisfaction; sense of community; and general characteristics. Results: The mean scores for the three dimensions were $39.2{\pm}6.44$ (compassion satisfaction), $31.9{\pm}3.59$ (burn out), and $26.4{\pm}5.05$ (secondary traumatic stress). A multiple linear regression revealed that compassion satisfaction varied significantly according to the satisfaction with job choice, sense of community, job stress, and job satisfaction. The factors affecting burn out were sense of community and work load, while the factors affecting secondary traumatic stress were education, job stress, and job satisfaction. Conclusion: The findings of this study suggest that comprehensive intervention focusing on improving the sense of community and job satisfaction and reducing job stress is essential to promote community health practitioners' ProQOL.

Background: This study examines quality of life (QOL) of a sample of police officers in India. The concept of QOL includes well-being, social obligations, relationships of a person, and his association with environment. The study examines the factors on which QOL of police officers depend and their relationships with each other. The issues linked with QOL are important because they directly affect the individual's ability to maintain a healthy lifestyle and affect organizational performance in the long run. This study explores relevant factors that have an impact on the QOL of the employees of police department in India. Method: In this paper, literatures review, ISM, MICMAC, and DEMATEL methodology have established eleven factors that impact the QOL of police officers in India. Mutual relations between factors have been established using the ISM approach to develop a model to represent these relationships. DEMATEL methodologies were used to analyze these factors. Results: Results indicate that "fair compensation, work overload, workplace safety, and job stress" are the top-level factors that affect QOL of police officers. Conclusion: The identification of factors and their mutual relationships that affect QOL are important for police officers and have to be dealt with according to their order of importance. The research model developed in this study shows how the factors of police officers' QOL are interrelated and presents the interrelationships among these factors. A comprehensive model depicting the relationships among these factors has been established, so that the QOL of police officers can be improved.

Given the critical role of information technology (IT) in achieving organizations' strategic goals, it becomes increasingly important for organizations to develop and retain a competent IT workforce. We investigate how organizations make IT personnel feel content with their job, motivate them to perform at their best, and consequently retain them. We develop a model in which IT leadership, conceptualized as "transformational" and "transactional" IT leader behaviors, influences IT personnel's perceptions of requisite soft skills and IT personnel's Quality-of-Work-Life (QWL), and how IT personnel's QWL in turn affects IT personnel's intention to stay. Using survey data from 205 IT professionals, we found that IT leadership behaviors, particularly transformational leadership behaviors, positively influence IT personnel's intention to stay. We also found that this relationship is fully mediated by IT personnel's QWL. In addition, we found that transformational leadership behaviors positively influence IT personnel's perceptions of requisite soft skills. We discuss the implications of our findings for theory and practice.
