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.

본 연구의 목적은 수학의 학업성취도에 미치는 영향요인에 대하여 기존의 연구들을 분석하고, 특히 학교수준에서 실시하고 있는 수학과 수준별 이동수업이 실질적으로 학생들의 수학 학업성취도에 영향을 미치는지를 실증적으로 분석하고자 한다. 선택편의를 최소화하기 위해 한국교육종단연구2005의 6차년도 데이터를 바탕으로 경향점수매칭법(propensity score matching)을 사용하여 수학 교과 수준별 이동수업이 수학성취도의 지표인 수능 수리영역 표준점수에 미치는 영향을 살펴보았다. 그 결과 수준별 이동수업과 수학성취도 사이의 양의 관계가 있음을 확인하였으며, 수준별 이동수업의 효과적 운영을 위해 정책적인 노력이 요구된다.

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.

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＇.

In this study, the consumers were classified into Risk Avoidance Group, Enjoyment and Economy Group, Low Involving Group and High Involving Group by shopping propensity of the consumers and investigated the difference in their evaluation criteria and purchasing intention. The samples used in this study are 214 university students in Busan area who visited the internet shopping mall or had an experience to buy clothes through an internet. The purpose of this study is to identify how the internet university students' clothes shopping propensity and demographical factors affect the evaluation criteria and purchasing intention for clothes. And based on the results, the implications for internet clothes shopping mall are suggested and post research subject is provided as well.
