Today, consumers need more information of well-being related food with an increase of interests in health. Thus it is important to understand and provide well-being food related information to consumers. This study was performed to investigate consumer needs for well-being food related information. The needs scores (5-point Likert scale) to well-being food related information were high over all. The highest score was observed in 'disease care and diet therapy' (4.05 point). 'Functionality of well-being food' and 'safety and hazard of food' were followed having high scores (individually 4.00, 3.99 point). Female subjects had higher information needs than male subjects for well-being food related information such as 'balance of diet', 'nutrients' and 'recipe of well-being food'. The needs for well-being food related information increased by age, although subjects who were over 50 had a decrease in information needs. There was a significant positive correlation between the majority of well-being food related information and educational level. Information needs were not significantly different by income. Conclusively, well-being food related information should be provided to consumers according to the individual needs and ultimately consumers will improve their efficiency and satisfaction in using well-being food related information.

Korea's general rural development projects, which has shifted its paradigm to a bottom-up approach, should be promoted in the direction of focusing on the subjective well-being of the residents in rural areas. This study analyzed the effect that a general rural development project impact on the subjective well-being of the residents and the village leader in the relationship the spirituality of leadership, the village's social capital to analyze the impact any general rural areas, attributed the success of development projects with diversified.. The results are as follows: First, the basic living-based projects among general agricultural fishing village development projects have positive effects on the subjective welfare of the residents. Second, it was found that the basic living-based projects and regional income raising projects in general agricultural fishing village development projects had a positive effect on the altruistic behaviors and beliefs of spiritual leadership. Third, as a result of analyzing the effect of the level of general farming and fishing village development on social capital, regional income raising projects have a positive effect on the formation of social capital such as trust and network. Finally, as a result of analyzing the influence of social capital on subjective well-being, it was found that social capital such as trust and network has a positive effect on the subjective well-being of rural residents. In future research, it is required to select more extended research subjects not limited to residents of limited areas, and conduct repeated studies, with expanding the model to include the important variables that affect the subjective well-being of the residents.

Drilling at unconsolidated layer can make the aquifer disturbed and reduce a productivity of groundwater well. Surge block and air surging were applied to a pumping well located in Jeungsan-ri, Changnyung-gun, to improve a well efficiency by removing clogging and fine-grained slime. Two experimental log-linear equations, $y_1=-0.1769\;ln(x_1)+0.4960$ and $y_2=-84.3358\;ln(x_2)+512.8162$, were proposed in this site, in which $x_1$ and $x_2$ are the number of surging event, $y_1$ is the amount of slime, and $y_2$ is a recovery time of groundwater level after air surging. Well loss exponent (P) decreased after surging, from 3.422 to 1.439, and the groundwater inflow from aquifer happened in all directions around a well with gradually increasing the homogeneity in a local aquifer's hydraulic property. It was revealed that long-term well development should be done in the pumping well which is located in unconsolidated sediments to increase a well productivity.

Background: Research on the impact of psychosocial risks on well-being at work remains scarce in low- and middle-income countries, especially in the banking sector. This study sought to examine the relationships between job demands, job resources, well-being, job satisfaction, and work engagement in the Zimbabwean banking sector. Methods: An online survey was administered to 259 employees from five banks. Hierarchical multiple regression tested the relationships between job demands (quantitative demands, emotional demands, work pace, and work-family conflict), job resources (possibilities for development, social support from colleagues and supervisors, quality of leadership, and influence at work), well-being, work engagement, and job satisfaction. Interactions between all variables were tested. Results: Job demands were negatively related to well-being, work engagement, and job satisfaction. Job resources had positive relationships with the same. Work pace had positive relationships with well-being and work engagement. Influence at work moderated the relationship between emotional demands and work pace with well-being. Possibilities for development moderated the relationship between work-family conflict and well-being. Work-family conflict moderated the relationship between social support from colleagues and job satisfaction. Emotional demands, work pace, and quantitative demands moderated the relationship between influence at work with job satisfaction and work engagement. Conclusion: Job demands should be reduced where possible in order to enhance employee well-being, work engagement, and job satisfaction. The job resources that should be availed to facilitate a positive psychosocial work environment in the banking sector include social support from supervisors, influence at work, and possibilities for development.

The study attempted to explore the dimensionality of mother's psychological well-being. The major purpose of the study was aimed at establishing the construct validity regarding the instrument of assessing mother's psychological well-being. Instrument for assessing psychological well-being was developed with 9 variables(sense of control, sense of achievement, sense of confidence, sense of acceptance, sense of intimacy, sense of assistance, sense of immersion, sense of hope, and sense of satisfacion) in 3 dimensions(sense of competency, sense of relation, and sense of improvement) with 4 rating scales of 102 items. After the scale development, the estimates of reliability for the 9-variable scales were Cronbach's ${\alpha}=.71{\sim}.90.$ The correlation between the two scales, Psychological Well-Being Index(Franklin, 1996) and Psychological Well-Being(Ryff & Keyes, 1995) was .21~25. The subjects were divided two groups by the score of the Mother's sense of Psychological Well-Being. And the group has hiher score in Mother's sense of Psychological Well-Being showed the higer score of Perceptions of Parental Role Responsibilities Scale(t=3.24, p=.002).

To investigate the effect of aquifer disturbance on hydraulic properties while well drilling at unconsolidated aquifer, the following tests were conducted: the surge block and air-surging methods, which are well development methods used after well drilling; and step-drawdown tests and constant-rate pumping tests, which are used to assess changes in the aquifer after well drilling and development. The result of step-drawdown tests indicated that drawdown for a pumping-rate of $700m^3/day$ was 21.62 m after well development, decreasing 4.39 m from 26.01 m after well drilling. The skin factor used to identify the well properties decreased from 7.92 after well drilling to 5.04 after well development, respectively, which shows the improvement of well. Constant-rate pumping tests revealed a small increase in aquifer transmissivity after well development at MW-2, -3, and -4, centering around pumping well, from $1.684{\times}10^{-3}{\sim}4.490{\times}10^{-3}m^2/sec$ to $4.002{\times}10^{-3}{\sim}4.939{\times}10^{-3}m^2/sec$. MW-1, however, showed decline in hydraulic conductivity from $1.018{\times}10^{-2}m^2/sec$ to $6.988{\times}10^{-3}m^2/sec$, which was caused by a small decrease of aquifer permeability around monitoring well MW-1 due to latent factor of air interception and clogging in aquifer during surging. This finding indicates that fine particles have an effect on hydraulic properties at unconsolidated aquifers during well drilling; therefore, we consider that well drilling and development have an effect on hydraulic properties.

The purpose of this study was to explore the effects of child gender and temperament, husbands’ support, and mothers’ psychological well-being on maternal parenting behaviors toward toddlers. Mothers of 214 toddlers responded to questionnaires on the following variables: child temperament, husbands’ support, psychological wellbeing and parenting behaviors. Hierarchical regression analysis revealed that: 1) Children being negative emotionality linked with mothers’ high controlling and rejective parenting behaviors and low responsive parenting behaviors directly and indirectly via mothers’ psychological well-being; 2) Husbands’ support was linked with mothers’ low controlling and rejective behaviors through mothers’ high psychological well-being; 3) Mothers’ low psychological well-being was linked to high mothers’ controlling and rejective parenting. The results of this study underscore mothers’ psychological well-being and husbands’ parenting support in predicting mothers’positive parenting.

The purpose of this study was to minimize salt water intrusion into freshwater aquifers and limit the development of freshwater aquifers, by selecting an appropriate excavation depth of in the western coastal area of Jeju Island. The study site was mostly basaltic lava, which was mainly composed of trachy basalt. A vertical logging test was conducted to investigate the vertical distribution of the groundwater and saline groundwater interface in the study well. It was found that freshwater groundwater, saline groundwater, and freshwater groundwater are distributed from the surface to approximately 16 m, 16~50 m, and 50~60 m, below the ground, respectively. In order obtain saline groundwater and minimize the inflow of freshwater into this well, the drilling depth should be limited in the range of 16~50 m from the surface. Thus, saline groundwater well development should be carried out with reference to the measurement results, which depend on the drilling depth and EC (electrical conductivity) obtained with drilling apparatus for geology and ground handling.
