For the development of a new antidementia functional food or alternative drug using agricultural products, Job's tears (Coix lachrymajobi L.), which shows high acetylcholinesterase (AChE) inhibitory activity (55.1%) was selected and the extraction conditions of AChE inhibitor were optimized. AChE inhibitor of Job's tears was maximally extracted when it was treated with 60% methanol at $40^{\circ}C$ for 6 h. The AChE inhibitor of the methanol extracts was partially purified by systematic solvent extraction, thin layer chromatography, silica gel chromatography and reverse-phase HPLC and the partial purified AChE inhibitor with inhibitory activity ($IC_{50}$) of $0.608\;{\mu}g$ was obtained. The partial purified AChE inhibitor was soluble in methanol and hexane, and insoluble in water. Its maximum absorption spectra was 230 nm and also it was stable in the range of $30^{\circ}C$ and $70^{\circ}C$ and pH 4.0-8.0 for 1 h.

The number of Healthy Family Support Centers has dramatically increased during the past eight years since the Framework Act on Healthy Families was enacted. This phenomenal growth is largely credited to Certified Healthy Family Specialists (CHFSs). Despite their contributions, the job and working conditions of the CHFSs have rarely been explored from the insiders' perspective. In this study, we aim to delineate CHFSs' job and working conditions from their own narratives in order to improve an understanding of CHFSs' profession and work environment. We conducted in-depth interviews with nine CHFSs and a focus-group interview with five CHFSs. Our findings revealed that CHFSs took pride in their professions, internalized their professional mission of enhancing family strengths, and highlighted CHFSs' unique professional role in comparison to other human services professionals. In conclusion, CHFSs showed a strong professional identity consisting of rich professional knowledge, solid career goals, and integrated socio-political values. Contrary to the positive perception of the CHFSs' job, CHFSs expressed challenges in their working conditions in terms of small-scale organizations at local Healthy Family Support Centers, a heavy workload, hierarchical relationships with local government officers, and the unsatisfactory payroll and promotion system. This study contributes to a better understanding of CHFSs' job and their working conditions and provides insights on how to enhance professionalism among CHFSs and their work environment. As for policy implications, we suggest advancing qualifications for CHFSs, improving professional training programs for current CHFSs, and expanding small-scale organizations.

Objectives: This study was designed to investigate the current status of the association of job-related information such as employment status, workplace environment, and hazard material exposures with health examination outcomes. Methods: The study used data from KNHANES 2007-2009 representing the three years of 2007-2009, which was conducted annually using a rolling sampling design that involved a complex, stratified, multistage, probability-cluster survey of a representative sample of the non-institutionalized civilian population in Korea. The final analytical sample consisted of 17,240 participants. Information on age, education, smoking history and alcohol intake was collected during the health interview. Job related information consisted of employment status, workplace environment, and hazardous material exposure. The selected indices of health examination were blood pressure, fasting glucose, blood cholesterol, HDL, SGOT, SGPT, and BUN. Results: In multiple logistic regression analysis using hypertension and pre-hypertension as dependent variables and job related categories as independent variables after covariate adjustments, the odds of hypertension and pre-hypertension were significantly lower in those with responsibility and power in their job activities. Interestingly, low odds for hypertension were observed among those who reported that their jobs were fast-paced. Conclusions: This study confirmed that some job-related categories in employment status, workplace environment, and hazardous material exposure had an association with health outcome status. It is worthwhile to comment that high responsibility and power in job activities were revealed as one of the important favorable factors to improve health condition of workers.

Purpose: The CHP program has been evaluated as one of the most successful program in the public health area in Korea. The objects of this study were as follows: 1) to evaluate the job activities of the CHP program, using service contents analysis. 2) to figure out personal factors and the outcome of CHP's activities. Method: Data were collected by sending questionnaires to 130 subjects through the mail from May to December 2003. The response rate was 48.0%. The Data were analyzed by the SPSS WIN program with t test and Pearson correlation coefficient. In using these methods. independent variables are CHP's personal factors (age, experience, certification of specialty) and regional factors (geographical classification, aged population, village workers, cooperation of community leaders, work-conditions), and a dependent variable is the outcome of CHP's job activities. Result: The results of t test analysis show that regional differences between factors are influential in the welfare service, the routine job, and the consultation. As a whole, this is shown that CHPs represent experience, the number of village workers and CHPs living condition of work and most of the categories of jobs that influenced over statistical meaning of differences (t=2.417, p=1.043, t=6.123, p=.004, t=4.309, p=.000). There is a significant positive relation between the routine job and the consultation(r=.455, p=.000), the consultation and the education(r=.461, p=.000). Conclusion: Finally, according to the results of this study, the CHP program should be developed and continue to meet the basic health care needs of the residents in accordance with the philosophy of their own primary health care.

Drawing on costly signaling theory and self-enhancement motive, this study examines the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. In addition to the individual characteristic, this study considers job characteristics as conditional factors, and especially proposes the moderated mediation model in which job complexity and variety moderate the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. To prove these hypotheses, empirical analyses are conducted with 166 dyad samples collected from various industries. As predicted, individuals with high proactive personality are more likely to become involved in knowledge sharing behavior, and this behavior increases organizational recognition rated by their supervisors. Moreover, job complexity and variety moderate the positive relationship between proactive personality and organizational recognition is mediated by knowledge sharing behavior. These results reveal the motive in knowledge sharing and the boundary condition that is necessary to increase such behavior. The study findings will ultimately contribute theoretical and empirical implications to the knowledge management literature.

The e-commerce had been expanding in the distribution channels, recently. Then, COVID-19 and social distancing rules led to a surge of online hypermarkets volume. In this study, we examined workplace environments of delivery drivers, firstly. Second, this study was also designed to examine the influencing factors of the perceived working environments change on the job satisfaction, dealing with the recent surge of work. We analyzed 324 data using various ways like descriptive statistics, one-way analysis of variance, factor analysis, and hierarchical regression analysis. The analysis revealed that their job satisfaction was lower than the average score and their working time was too long. In addition, the changes of the workplace environments were divided into labor intensity change and working condition change, which all had a significant effect on job satisfaction. So we should devise some long-term and short-term plans to make the level of job satisfaction among delivery drivers high on workplace environments.
