The purpose of the study was to examine the effects of household characteristics to family savings. Family savings were defined in four ways such as monthly savings, average propensity to save, financial assets, and net financial assets. The household characteristics dealt with were family income, household size, number of earners, age, occupation, education, housing tenure, and urbanization. The data used in the study was Survey of Family Finance 1990. The main statistical method was multiple regression. Family income was found to the most important variable to determine four family saving variables holding other characteristics constant. Also, household size had significant negative effects on family savings. Two-earner households were found to have higher average propensity to save and less financial assets compared to single-earner households. Fro monthly savings and average propensity to save, the households with forties andfifties household head tended to be less than others, while financial assets tended to increase with the age of household head. Compared to salary earner households, blue-colored households had significantly lower average propensity to save, and the households with professionals had significantly higher financial assets. The college-graduated households tended to have less monthly savings than the elementary-graduated households. Also, the housing renters were found to have more monthly savings and higher average propensity to save, compared to the housing owners.

In this study, we estimate the effect of ability grouping on mathematics achievement empirically. We use propensity score matching(PSM) method to minimize selection bias and estimate the effect of ability grouping on the mathematics standard score of Scholastic Ability Test with the KELS(Korea Education Longitudinal Study) 6th stage data. The result indicated that relationship between ability grouping and mathematics achievement is positive and Policy efforts is needed to operate ability grouping effectively.

The investigation of effects on fouling propensity with various viscosity of feed solutions would be better understanding for forward osmosis (FO) performance since the fouling propensity was directly influenced with solution viscosity. Therefore, this study was focused on the FO fouling with model foultants (humic acid, alginate) by altering solution viscosity with change of ionic strength (I.S) and $Ca^{2+}$ concentrations. In the comparison between humic acid and alginate, as expected, the alginate generally caused more severe fouling (almost 35.8 % of flux reduction) based on the solution characteristics (high viscosity) and fouling patterns (coil and gel layer). However, interesting point to note is that the fouling propensity of alginate was more severe even though it was applied with low viscosity of feed conditions (I.S = 20 mM, $Ca^{2+}=1mM$). This might be due to that crossed linked gel layer of alginate on the FO membrane surface could be best formed in the condition of $Ca^{2+}$ presence and higher I.S, and that is more dominant to fouling propensity than the low viscosity of feed solutions.

The purpose of this study is to analyze whether SMEs' technological capabilities and international marketing capabilities affect the export performance of the SMEs and to empirically test the moderating effect of the CEO's risk propensity on such a relationship. We obtained data from 190 SMEs located in Gwangju and Jeonnam Province in Korea through survey and performed a regression analysis for hypothesis testing based on these data. As a result of the analysis, it was found that SMEs' technological capabilities and international marketing capabilities had a significantly positive (+) effect on export performance, respectively. Also, the CEO's risk propensity was found to reinforce the relationship between technical competence and export performance, and the relationship between marketing capabilities and export performance was also found to be strengthened in the positive (+) direction. These results suggest that it is necessary for SMEs to continuously develop technological capabilities and international marketing capabilities to achieve successful export performance in overseas markets. Also, the CEO's propensity to promote these relationships may be important.

Vehicle rollover is an important issue for the traffic safety. Rollover can occur from the driver's action, the vehicle characteristics, or the road condition. This study is about the rollover propensity analysis of a jeep vehicle using the steering and braking maneuver, which is the combined result by the driver and the vehicle. Simple equations of roll motion is used to analyze the roll motion and a special purpose vehicle dynamics program is used to simulate the rollover of the jeep vehicle. From the simulation, an incipient rollover motion of the vehicle was found. However, the more complete rollover propensity analysis would require further investigation using roll dynamic sensitivity study.

The purpose of this paper is to examine the relationship between the social interactions on the social network and the purchase intention. And the trust propensity of a trustor, the ability of a trustee, and the sincerity of a trustee are selected as the antecedents of social interactions. This paper also examines the effect of type of product as a moderating variable. The result of this paper reveals that social interactions(in terms of closeness, familiarity, and interpersonal trust) have a positive(+) effect on the purchase intention. The more social interactions, the more trustors have intentions to purchase the recommended products by trustees. In addition, the study reveals that the trust propensity of a trustor and the ability of a trustee directly and indirectly influenced on the intention to purchase the recommended product. The findings also suggest that the trust propensity of a trustor and the ability of a trustee have an effect on the closeness, familiarity, and interpersonal trust resulting from social interactions.

The purpose of this study is to explore an effect of education in faith and propensity of managers towards faith on job satisfaction. We found that education in faith has a significant effect on the role conflict. Propensity of managers towards faith also influences the job satisfaction. On the other hand, Education in faith and role conflict do not have a significant effect on the job satisfaction. Conclusions and implications are discussed.

The purpose of this study was to find out efficient control plan for productivity increase. To analyze the data, the measure of question a paper was used to 5 a point measure, statistics disposition was used to SPSS, the analyze method was used to frequency analyze, trust degree analyze, difference analyze useful average value, person's correlation analyze, revolution analyze. The results of this study could be explained as follow: First, find out high change separation propensity. Secondly, was subjected important for atmosphere composition and was required strategy consideration for stable job recognition. Third, was operated affirmative to recognition about separation and was increased to job satisfaction according as a colleague relation and team work. Fourth, was increased to comparative separation propensity in case that high job satisfaction. Therefore it is required interesting labor item and treatment development about personal evaluation.

Relationships between consumer socialization factors and socioeconomic characteristics and consumptionism propensity were examined using a sample of 529 middle school students in Inchon, Korea. OL.S regression was utilized. ＇Communication with friend＇ and ＇acceptance of mass media＇ had significant positive effects on ＇ego-identity developing and differentiating by uniqueness＇ and ＇other oriented and appearance pursuing＇ propensity, whereas had a significant negative effect on ＇consumption orientation＇, ＇Communication with mother＇ had a significant positive effect on ＇consumption orientation＇. Boys where significantly higher than girls in ＇ego-identity developing and differentiating by uniqueness＇ and girls were significantly higher than boys in ＇other oriented and appearance pursuing＇. ＇Income had significant positive effects on ego-identity developing and differentiating by uniqueness＇.
