This study analyzed the impact of women's self-preservation on their intention to start a business by using self-efficacy as a mediation, reflecting the importance of women's self-preservation to adapt to the new environment of start-up. In particular, in addition to the overall self-preservation, the sub-factors of behavioral delay, compensatory natural strategy, and constructive thinking strategy were also validated. As a research method, 198 people who responded to the online survey were analyzed using Model 4 of the PROCESS macro proposed by Hayes(2018), and indirect effects were analyzed by designating 5,000 bootstrapping samples. The findings were as follows. First, self-efficacy has been shown to have a mediating effect in which women's self-preservation influences their intention to start a business. At this time, the medium effect was shown as a partial medium. Second, the sense of self-efficacy was found to have a mediating effect on women's behavior-oriented strategies affecting their intention to start a business. At this time, the medium effect was shown as a partial medium. Third, self-efficacy was found to have a mediating effect in which women's natural compensatory strategies affect their intention to start a business. At this time, the medium effect was shown as a partial medium. Fourth, self-efficacy was found to have a mediating effect in which women's constructive thinking strategies affect their intention to start a business. At this time, the medium effect was shown as a complete medium. This shows that the higher a woman's self-preservation, the higher her self-efficacy and willingness to start a business. Based on the results of these studies, he made a developed proposal for women's start-ups.

Korean type of no-tillage cultivation method which was applied on this study used the ridge and the furrow and constantly recycling them as it was suitable for Korea's weather and farming conditions. This no-tillage cultivation was reported to have little negative impact such as reduction of production (Kwon et al., 1997). In addition, it was found to have a lot of benefits as it requires less agro-materials and energy costs as well as shortened working hours because tillage operation is not needed. (Yang et al., 2012). According to an analysis, no-tillage cultivation can reduce greenhouse gas emissions by $344.7kgCO^2$ (58%) in every 10a ($1,000m^2$) compared to ordinary pepper farming technique (Korea averages). Direct-indirect reduction effects from using fertilizer and using less amount of energy were 92% and 44% respectively both of which can be considered very high. Besides the direct effects of no-tillage cultivation, soil management using no-tillage technique raises carbon sequestration effect on soil as time goes on (West & Marland, 2002), that is why the technique is expected to have constant carbon emission reduction effect. For theses reasons, distribution and expansion of Korean type no-tillage cultivation are expected to play a role as major agro-green technologies for achieving our goal of reducing greenhouse gas emissions in agricultural sector.

We analyze the efficiency of congestion pricings and transit subsidies in the spatial micro-economic model based on a general equilibrium environment. In this setting, we decompose the total welfare change into component factors and identify the reason of the change in the efficiency caused by policy instruments; these component factors are divided into indirect factors and direct factors including of origin-destination and mode choices. We set up the model as adding mode choice to the standard format in the fashion of Anas and Kim (1996) and extend the methodology proposed by Yu and Rhee (2011) and Rhee (2012) for deriving theoretical and analytical solution. Most of welfare gain comes from the modal shift from car to bus. The relative efficiency of subsidies in relation to the first-best pricing is lower than it of congestion pricings although the change in bus share by subsidies is similar to it by congestion pricing. Subsidies give rise to more modal shift from a car to a bus for long-distance commuting than it caused by congestion pricings. As the increase of bus share for long-distance commuting leads to the increase of cross-commuters passing through CBD, the welfare gain by subsidies is lower than it by congestion pricings.

This study aimed to examine the model to explain the mediator effect of care evaluation(care stress, care satisfaction) on the effect of stress factors and resource on the psychological well-being of the parents of the adult intellectual disabilities. Examining whether there is a difference between the gender of parents was another aim of this study. Study results showed that with the care stress as an endogenous variable, the daily life function and maladjustment behavior of adult children and the health state of parents had a significant direct effect on the psychological well-being of parents. With care satisfaction as an endogenous variable, family support, expert support and care stress had a significant direct effect. With the psychological well-being as an endogenous variable, care satisfaction and care stress had a significant effect, but the health state of parents didn't. In case of indirect effect, the care stress had a significant mediator effect on the effect of the physical function and maladjustment behavior of adult children and the health state of parents on the psychological well-being of parents. Care satisfaction had a significant mediator effect on the effect of family support, expert support and care stress on the psychological well-being of parents. According to the result of the Multiple Group Analysis, the path showed a statistically significant difference between gender was friend support→care satisfaction, care stress→psychological wellbeing, expert support→care satisfaction. On the basis of the study results, practical suggestions were made.
