The purpose of this study was to investigate the effects of Engel coefficient, Angel coefficient and Schwabe index influencing Household head's life satisfaction. For this study, the data from the 8th analysis of the 2013 Korea Welfare Panel Survey conducted by Korea Institute for Health and Social Affairs were used. For the sample, 903 male Household heads with children under the age of 18, were selected. For statistical analysis, SPSS program (Ver. 21.0) was used. And for statistical methods, frequency and percentile, mean and standard deviation, Pearson's correlation, one way analysis of variance, Duncan's multiple range tests, multiple regression analysis were used. The findings are as follows. First, as a results of analyzing the food costs, education costs and housing costs depending on Income Quintile, the food costs and education costs in the 5th Income Quintile compared with other Income Quintile, were highest. Also, the highest housing cost was in the 2nd Income Quintile, while the least housing cost was in the 1st Income Quintile. Second, by analyzing the differences of Engel coefficient, Angel coefficient and Schwabe index according to Income Quintile, the results show that Engel coefficient and Schwabe index decreases as Income Quintile increases, and Angel coefficient increases as Income Quintile becomes higher. Third, the level of HH's life satisfaction according to Income Quintile, 1st Income Quintile, 2nd Income Quintile, 4th Income Quintile, 3rd Income Quintile, 5th Income Quintile in order, increased. Fourth, as the result of analyzing the influence of Variables related to household and demographics about Engel coefficient, Angel coefficient and Schwabe index, it was shown that the variables effecting Engel coefficient, Angel coefficient, and Schwabe index are age, occupations, Number of workers, House ownership, Income Quintile. Fifth, As a result of analyzing the Variables effecting life satisfaction, especially while Schwabe index is not that significant, Engel coefficient and Angel coefficient are shown to have a significant influence. Therefore, the influence of Food costs and education costs can be confirmed.

Purpose - The purpose of this research is to explore the determinants of marriage intention for Korean youth. Because Korean society is under the population decline, inspecting influential attributes become worthy. Design/methodology/approach - This study employed Korean Youth panel data. The determinants of marriage intention include subjective health, leisure time, Schwabe index, culture recreation ratio, and Engel coefficient. This study performed binary logistic regression to test the hypotheses. Findings - The results indicate that subjective health and leisure time positively impact on the likelihood of marriage intention. However, culture recreation ratio and Engel coefficient negatively affect the likelihood of marriage intention. Schwabe index exerts no significant effect on marriage intention. Research implications or Originality - The results could become useful information to build policy to solve the population decline problem

Farm households consumption pattern from 1960 to 1968 was analized as follows. First, the influence of the price on the consumption pattern was observed by year for 9 years. Second, the influence of farm households and by size of the consmption pattern was analized by year for whole household and by size of the arable land. Third, the present status and problems of farm families consumption pattern was attempted to be found out compared with the pattern of all families of Seoul. Forth, the pattern of food expenditure which has the largest proportion in the living expenditure was analized. Following results and conclusions are obtained from the above analysis.1. The average nominal increase rate of all farm households has been increased gradually for 9 years, mostly due to the rise in household goods prices paid by farmers. 2. The living expenditure varies with the price and the disposal income, The influence of the latter is greater than that of the former. 3. The Engel's Coefficient of farmers. the average of which was 54.9%, recently tends to decrease gradually. The larger is the size of arable land, the lower is the Coefficient of farm households. But the Coefficient of farm households is higher than that of city families. 4. In general the proportion of food expenditure has a great influence on the consumption pattern, The average percentage of miscellaneous expenditure is 23.9% and it is next to food expenditure. The relationship between them is going reversely. Housing expenditure has usually the constant proportion. But the difference of the proportion between farm households (4.0%) and city families (17.1%) is considerable. Clothing expenditure and fuel and light expenditure have small variations. The former tends to increase with the income, and the latter tends to decrease with it or is constant. 5. Considering the food expenditure pattern, the average percentage (78.4%)of staple food of farm household is remarkably high compared with Seoul (48.3%) and other cities (54.0%). The decrease of the percentage of staple food expenditure in farm households is not so much as cities. 6. The propertion of the staple food expenditure of Farm families don't have so much differences by the size of arable land. But the rice proportion of staple foods has the tendency to increase with the income level. Subsidery food expenditure doesn't increase by year and by size of the land, while the consumption of meat and manufactured foods tends to increase with size of the land. But even big farm households don't reach to the level of cities in consumption of them. 7. Food consumption pattern may be influenced by the factors such as the knowledge of wife about nutrition, customs, consumption habits, and so on. The difference between farm households and city families in food consumption pattern is inferred from the above factors. Presently, the increasing income of the people promote the consumption of all items of living expenditure both in cities and farm households. But the Engel's Coeffcient and the proportion of the staple food expenditure is expected to decrease in farm households more than in cities.

The appraisals of hydrology model behavior for flow and water quality are generally performed through comparison of simulated data with observed ones. To perform appraisal of hydrology model, some criteria are often used, such as coefficient of determination ($R^2$), Nash and Sutcliffe model efficiency coefficient (NSE), index of agreement (d), modified forms of NSE and d, and relative efficiency criteria NSE and d. These criteria are used not only for hydrology model estimations also for various comparisons of two data sets; This NSE has been often used for SWAT calibration. However, it has been known that the NSE value has some limitations in evaluating hydrology at watersheds under monsoon climate because this statistic is largely affected by higher values in the data set. To overcome these limitations, the SWAT auto-calibration module was enhanced with K-means clustering and direct runoff/baseflow modules. However the NSE is still being used in this module to evaluate model performance. Therefore, the SWAT Auto-calibration module was modified to incorporate alternative efficiency criteria into the SWAT K-means/direct runoff-baseflow auto-calibration module. It is expected that this enhanced SWAT auto-calibration module will provide better calibration capability of SWAT model for all flow regime.

The purpose of this study is to identify the possibility of unemployed married women's economic activity by analysing their willingness to work and possible influencial factors on it. This study estimates the effects of independent variables on the dependent available by using Binomial Probit Model. sample are 592 two-parent households. The results of this study are as follows ; The percentage of unemployed married women's willingness to enter into the labor market is 25.2%. Among the variables which have affected their willingness are family variables(family size, the number of children and the existence of children under the age of 6), personal variables(the age, education level and the past working experience) and financial variables(non-wage income, Engel's coefficient, expenditure o leisure activities and the subject judgement of their financial status). It is hard to accept those women's low willingness as is since the most crucial statistically was especially the children of 6 or less among the family variables. That is to say, more favorable conditions of the labor market and inexpensive day-care centres available would certainly encourage married women to be more willing to participate in economic activities as employees.

This study aimed to investigate the change in food balance and dietary patterns, caused by the growth of per capita GNP during $1962{\sim}1987$. For the purpose of this analysis, ordinary least square (OLS) was adopted. Per capita GNP was independent variable and the other factors dependent variables. The other factors included Engel coefficient, food supply, energy supply, nutrient intake and the ratio of self-supply of food. The result revealed that the some variables have (+) correlation, the some variables (-) correlation and the other variables no correlation with per capita GNP. If forecasting models are designed with these results, it will be helpful for national health and nutrition, food balance and disease prevention.

This study is designed to forecast the characteristics in food consumption patterns under per capita GNP growth. Ordinary least square(OLS)method was employed as analyzing technique. Equation was $Y=a_0+a_1X$, in which X was per capita GNP and Y were Engel coefficient, food supply, energy supply, nutrient intake and ratio of self-supply of food. The result obtained indicates that the intake of nutrient such as protein and fat will be increased, and wheat, corn and legume are expected to be imported wholly due to lower ratio of self-supply, and rice will be over-supplied continually. Therefore, the relevant policy of government must be established in the field of supply and demand of food, and the research of sound national health should be done.

The purposes of this study were to identify education expenditure and to analyze contributing factors to total education expenditure for two children among married couples. For these purposes, total sample of 1,256 married couples those having two children of both pre-school aged and school aged were selected, and total sample was divided into four groups by first child's school aged; those were pre-school aged(375), elementary school aged(385), middle & high school aged(248) & college aged(248). Statistics used for the analysis were frequencies, means, percentile, and tobit and OLS analysis. The results were as follows. First, the households those having the first child of pre-school aged didn't spent for public education expenditure, while public education xpenditure of school aged increased continuously. The households having the first child of high school aged spent the most private education expenditure among four groups, however, total education expenditure of the households having the first child in college aged spent the most education expenditure were household head's age, family size, home ownership and financial asset amount, and elementary school-aged's factors were household head's age, education level, home ownership and total household income. Also, household head's education level, wife's expectation of future economy, residence, total household income had significant effects on total education expenditure in middle and high school-aged, and household head's job, home ownership, contact with neighborhood, residence and Engel's coefficient were significant variables in college aged.

이 연구에서 얻어진 분석결과는 다음과 같다. 1) 계층별 영양섭취실태에서는 지주층이 가장 양호하였는데 비해 농업노동자 및 소작농층은 대부분의 영양소가 권장량에 미달하였으며, 특히 칼슘은 모든계층에서 결핍되고 있었다. 이외에도 열량과 단백질, Vitamin A 등이 지주 및 부농을 제외한 계층들에게 각각 부족을 나타냈으며, 이는 특히 열량 및 단백질의 질적구성에서도 더욱 현저하였다. 2) 식품소비를 가장 많이하는 계층도 지주층이었고, 그 다음이 부농, 중농층이었는데 비해 가장 적은 소비를 보인 계층은 농업노동자층이었다. 식품군별로 보면 지주층은 채소류, 어패류등에서 그리고 부농층은 유제품, 유지류등에서, 또한 과일류, 육류, 계란류등에서는 이들 두 계층의 소비가 가장 컸는데 비해, 중소농층은 채소료, 해조류등에서 평균 이상의 소비를 하였다. 지난 10년간 소비가 급증된 식품은 부농층은 청량 음료등을 지주층은 어패류등을 들었는데 비해, 나머지 계층들은 쌀밥등을 가장 많이 들었다. 이러한 식품소비의 변화에 대한 이류로는 지주층은 도시적 생활양식의 침투를 부농 중농 소작농층은 소비성향의 변화를 그리고 무의식적 추종을 든 계층은 주로 농업노동자층과 소농층이었다. 3) 사회경제적 지표와 영양섭취층과의 관계에서는 열량과는 학력이, 또한 단백질은 토지소유면적과 농가소득이, 그리고 칼슘은 부채 및 농업소득와의 상관이 깊었다. 특히 농가소득과 단백질섭취량간의 계층별 상관 및 희귀관계를 보면 지주, 소작, 중농의 순으로 상관이 컸으며, 희귀분석에서는 전체적으로 1인당 연간 소득이 10만원 증가됨에 따라 단백질 섭취량이 약 4g증가 됨을 보여주었다(y=56.96+0.04x). 4) 사회경제적 지표와 식품군별 소비지출과의 상관 관계를 보면 학력과 가장 상관이 깊은 식품은 육류, 유지류등의 그너대적 식품이었고, 토지소유 면적과는 곡류 및 어패류등에서 그러하였다. Engel 계수와 곡류는 정의 상관이, 그리고 어패류, 육류는 높은 부의 상관을 보였고, 또한 어패류와 육류는 소득과도 높은 정의 상관을 보였다. 5) 마지막으로 계층간 식품소비 및 영양섭취의 불균등 정도는 동물성 단백질을 제외하고는 소득이나 토지 소유면적등 사회경제적 지표간의 격차보다 훨씬 낮은 수준에 있었다.
