The study purposes to compare consumer choice behavior of high school students with that of college students. Through a questionnaire survey, data were collected from 385 high school students and from 230 college students. The results were as follows; 1) consumer choice behavior patterns were sorted into 'the indifferent type', 'the bragging type', and 'the economic type'. 2) The college students tended to choose new products or famous brands, to do comparison and planned shopping, and to buy more on impulse than the high school students. On the other hand, the high school students tended to buy low-priced products or products at discount prices. 3) The female students chose new and low- priced products and bought more on impulse than the male students. 4) Most of female and male college students belonged to the 'bragging type'. 'The indifferent type' was the most common of male high school students. 5) 'The economic type' was the least of all college students and highschool students.

This study aims to evaluate the status of Korean healthcare among Organization for Economic Cooperation and Development countries and to monitor the trend of health care status since 2000. The position value for relative comparison (PARC) index was selected to gauge the level of healthcare status in demand, supply, accessibility, quality, and cost as per healthcare policy aspects. The Mann-Kendall test was conducted to allocate healthcare status of Korea since 2000. The PARC values indicate strength and weakness of Korean healthcare system by the mathematical comparisons. Korea positioned higher in demand, supply, accessibility, and quality. Yet, there are shortages in human resources and primary care. In conclusion, we suggest utilizing this study provides evidence to prioritize health care problems that can lead to establishing healthcare policy.

This study categorized the households into four by the comparison of wives' and husbands' earned income, such as one with higher wives' income than husbands' in dual-earner households, with higher wives' income than husbands' in household with unemployed husbands, with lower wives' income than husbands' in dual-earner households, and with lower wives' income than husbands' in household with unemployed wives. This study compared and analyzed the objective and subjective economic well-being, and overall satisfaction of life in those households. Major results are below. First, the amount of expenditures, saving, debt were low in one-earner household with employed husbands, but average propensity to expenditure was high in those households. The amount of saving was low in one-earner households with unemployed husbands, but the average propensity to expenditure and debt were high, resulting in the low status of economic well-being. The amount of saving and monetary assets were high, but average propensity to expenditure and debt were low in households in which wives had higher income than husbands, resulting in the high status of economic well-being. Second, husbands' satisfaction for the level of family income was not different among four groups of households. Wives's satisfaction for those was the lowest when wives' income was higher than husbands', but the highest in households with unemployed wives. Wives' and husbands' expectations for the future economic well-being of the households were negative in households with unemployed husbands. On the other hand, the level of satisfaction of wives and husbands for their life was not different among four groups of households. Finally, four groups of households were discriminated by age of husbands, number of children, debt, and wives' expectation for the future economic well-being.

Abstract: Korea has designated free economic zones to build the foundation for national economic development by setting up special economic zones to be more competitive in cities. On August 5, 2003, the government designated Songdo, Yeongjong and Cheongna districts in Incheon as free economic zones. But while the development should have been completed nearly three years before the end of the development, the development has been slow and the population, foreign direct investment and other business results are far from the initial plan. Therefore, in this study, we will investigate the various problems occurring in the Incheon Free Economic Zone, investigate the causes of the problem, and then compare and analyze the Incheon Free Economic Zone and China's special economic zones. The two institutions share similar characteristics in many areas, but the Incheon Free Economic Zone system has yet to be settled, as the special economic zone has played a significant role in economic development in China. Therefore, the study is expected to find a solution to the problems of the free economic zones in Incheon and provide directions for future development.

Measuring market fear is an important way of understanding fundamental economic phenomena related to financial crises. There have been several approaches to measure market fear or panic level in a financial market. Recently, herd behavior has gained its popularity as important economic phenomena explaining the fear in the financial market. In this paper, we investigate herd behavior in global stock markets with a focus on intercontinental comparison. While various risk measures are available for the detection of herd behavior in the market, we use the standardized herd behavior index in Dhaene et al. (Insurance: Mathematics and Economics, 50, 357-370, 2012b) and Lee and Ahn (Dependence Modeling, 5, 316-329, 2017) for the comparison of herd behaviors in global stock markets. A global stock market data from Morgan Stanley Capital International is used to study herd behavior especially during periods of financial crises.

This study investigated the healthcare status of South Korea and member states of the Organization for Economic Cooperation and Development (OECD). By employing the position value for relative comparison index, healthcare status was measured through the following components: demand, supply, accessibility, quality, and cost. Statistical analysis was conducted through the Mann-Kendall test from analyzing trends from 2000 onwards. Results showed that while Korea, on average, scores higher than the OECD average in most of the investigated components, it is below average in certain indexes including primary care and mental health care. Considering the various health issues that have been raised about these indexes, it is important these components be improved upon by policy-makers.

Variable sampling interval(VSI) and variable sample size(VSS) control charts vary the sampling rate for the next sample depending on the current chart statistic. This paper develops EWMA charts with the VSI and VSS features, and investigates the effectiveness of these charts in context of an economic model. The economic properties of these charts are evaluated by using Markov chain methods. The model contains cost parameters which allow the specification of the costs associated with sampling, false alarms, and operating off target. This economic model can be used to quantify the cost saving that can be obtained by using control charts with the VSI and VSS features instead of with the fixed sampling rate(FSR) feature, and can also be used to gain insight into the way that control charts with the VSI and VSS features should be designed to achieve optimal economic performance. The economic performance of X charts with the VSI and VSS features is also considered.

A dimension of well-being economic security was analyzed and compared with economic adequacy. Again it was tested whether two indicators of economic security(short-term vs. long-term) yield same distribution across all household groups. Economic Security was defined as the household ability to sustain a given level of consumption in the case of economic emergency; specifically loss of income. Measure of 8 different kinds of economic security were constructed from household net worth including and excluding home equity. Data were taken from the 1988 U.S. Consumer Expenditure Survey and 2148 households were selected to test hypotheses concerning the economic security of American households Empirical results showed a very low level of economic security in general. The first hypothesis that distribution of economic adequacy and economic security are same across all population groups was rejected. On the average security measure rather than adequacy measure was favor to white female-headed households and households who have old and highly educated house-holder. The second hypothesis that the indicators of long-term and short-term economic security yield the same results across all household was not rejected. In general the level of economic security was relatively higher when long-term indicator was used than short-term indicator was however the direction and relative size of effect of income and each control variable was almost same.

Purpose: Nowadays the Korean society is in the center of time of the social change. Because of dissociation of traditional family, IMF (International Monetary Fund) crisis and economic recession, the mortality rate of suicidal attempts are increasing annually. The majority of suicidal attempts were by poisoning considering the characteristics of korean society. Therefore we studied to find out the characteristics of suicidal poisoning before and after social economic stress, and to suggest the direction for the proper management. Methods: We reviewed medical records of 547 patients of suicide by poisoning who visited the emergency medical centers of St. Mary's hospitals from 1997 to 2004. For the annual trends analysis, we analyzed the demographic and toxicologic data of these patients compared with before and after IMF crisis (1998) and the economic recession ($2003\~2004$). Results: At the time of IMF and the economic recession, the number of suicidal poisoning increased, especially in fifth decade. The refusal rate of toxicological emergency treatment increased. Also the mortality rate and the admission rate to ICU (Intensive Care Unit) increased during the same period. In the result of the comparison analysis, clinical severity and mortality of social problem group were higher. However they couldn't be treated appropriately because of financial problem and the family indifference. Conclusion: At the economic recession period, the severity of suicidal poisoned patients was high. But the refusal rate of toxicologic treatment also increased, so the patients had lost the chance for proper toxicologic treatment. Therefore they would be supported by medical institution and public health.

The purpose of this study is to find differences in dietary patterns through menu analysis by economic status. The data was obtained from the 1998 and 2001 National Health and Nutrition Survey of Korea. The main variables were economic status, sex, and area by urbanization. The economic status was classified into low, middle, high, and top classes using a poverty line based on the 1998 and 2001 minimum standard cost of living. The areas were divided into metropolis, small city, and rural areas. The dishes of 3 meals were classified into 29 categories by cooking method. The most frequent pattern was "rice + soup + kimchi". The frequency of this Korean basic dietary pattern was the lowest in the top income class and metropolis areas, while the highest in the low income class and rural areas. The frequency of Korean recommended dietary pattern, that is, "rice + soup or stew + kimchi + side dish" was the highest in the top income class. The metropolis group preferred side dishes using meat and a cooking method that saved time, but the rural group preferred side dishes using vegetables and cooking methods that take a longer time. In comparison of dietary pattern between male and female by economic status, the higher economic status, the male's dietary patterns showed more side dishes than those of female. But the main side dish was kimchi in male low class. Consequently, the major dietary pattern in Korea is rice-style, though the western pattern is increasing in the top income class, especially in metropolis areas. Therefore, to make a better dietary pattern, we should develop and spread low-priced recipes of various side dishes and teach financial skills such as ability to make a food budget for lower income classes. Also, we should emphasize the importance of the balance between meat and vegetables and traditional diet and western diet for the top income class, especially in the metropolis areas.
