By analyzing 1998~2008 Korean Labor and Income Panel Study(KLIPS), this study examines socio-economic characteristics of people who become poor. The study also explores the reason why they are in the state of poverty. To find determinants affecting poverty entrance, discrete-time hazard models are applied. Major findings are as follows. The socio-economic characteristics driving people into poverty are in the middle way of the long-term poor and the non-poor, combining the characteristics of both groups. This implies that many cases of the newly poor tend to enter and exit from poverty repeatedly. Poverty entry rate was at a high level right after the economic crises, then was a downturn and remained fairly stable since 2000. However, the young, the high-educated, and even the professional are on the rise as a new poverty group. The major reason people become poor is temporary job loss. This factor is confirmed again by multi-variate analyses. In building anti-poverty policies, it is important to distinguish the long-term poor from the short-term poor. For the long-term poor, virtually the only affective policy will be income support. On the other hand, a labor-market strategy for jos security will be more effective for the short-term poor. The characteristics and determinants of poverty entry may affect poverty duration and exit in the future. Future research will be needed to investigate the relationship among these factors.

Foodborne outbreaks frequently occur worldwide and result in huge economic losses. It is the therefore important to estimate the costs associated with foodborne diseases to minimize the economic damage. At the same time, it is difficult to accurately estimate the economic loss from foodborne disease due to a wide variety of cost components. In Korea, there are a limited number of analytical studies attempting to estimate such costs. In this study we investigated the components of economic cost used in foreign countries to better estimate the cost of foodborne disease in Korea. Seven recent studies investigated the cost components used to estimate the cost of foodborne disease in humans. This study categorized the economic loss into four types of cost: direct costs, indirect costs, food business costs, and government administration costs. The healthcare costs most often included were medical (outpatient) and hospital costs (inpatient). However, these cost components should be selected according to the systems and budgets of medical services by country. For non-healthcare costs, several other studies considered transportation costs to the hospital as an exception to the cost of inpatient care. So, further discussion is needed on whether to consider inpatient care costs. Among the indirect costs, premature mortality, lost productivity, lost leisure time, and lost quality of life/pain, grief and suffering costs were considered, but the opportunity costs for hospital visits were not considered in any of the above studies. As with healthcare costs, government administration costs should also be considered appropriate cost components due to the difference in government budget systems, for example. Our findings will provide fundamental information for economic analysis associated with foodborne diseases to improve food safety policy in Korea.

Economic animal husbandry workers exposed to organic dust can be suffered from immunologic disorders. Our study was to determine immunological parameters related with occurrence of respiratory allergic diseases to animal husbandry workers in Korea for the first time. Peripheral blood were obtained from twenty-five pig barn workers, forty-nine chicken farming workers and fifty-one non-agricultural control workers. Significantly upregulated plasma IgE level was observed with pig-barn workers than that of chicken farming workers or healthy community control subjects. Furthermore, level of histamine, a hallmark of allergy induction, was upregulated in the pig and chicken farming workers in comparison with that of the control subjects. Downregulation of $IFN_\gamma$ and $TNF_{\alpha}$ production from T cells was apparent in the animal husbandry workers compared with the control subjects. Meanwhile, T cells collected from the pig barn workers demonstrated significantly higher production of IL-4 and IL-10 than the other groups. There were also alterations in IgG subclass distribution. In conclusion, immunological modulation probably leading to occupational allergic diseases can be occurred in the economic animal husbandry workers and the pig barn workers could be the most risky group to the work-related allergic disease.

In Korea, there are 1,474 thousand pumping wells nationwide which account for about 12% of total water use in 2012. As much as 39 hundred million tons of groundwater were used while 333 hundred million tons of total water were supplied in 2012. Because the water management authority projects that water demand will exceed supply by 2021, the authority is planning to extensively expand groundwater use in accordance with economic feasibility. Using the basic frameworks of cost-benefit analyses of the World Bank and the US Environmental Protection Agency (US EPA), the objective of this study is to examine the costs and benefits of the expansion of Korea's groundwater extraction through pumping wells. We conclude that the BC ratio of the groundwater pumping wells is 2.98. This signifies that the benefits are 2.98 times higher than the costs. The benefits include use and non-use values of pumping wells while the costs include the installation and maintenance of new wells, in addition to the restoration and pollution costs of abandoned wells, as well as fees for water quality tests, etc.

This paper investigates both the spatial patterns of aging population and its formal regional structure in 2010. The results are as follows: first, aging index shows high values in remote mountainous and coastal regions while showing relatively low values in Capital Region and large provincial cities. Aging index has low negative correlation with such variables as population increasing rate, ratio of youth population, ratio of apartments, and ratio of newly built housing. However, aging index shows high positive correlation with variables including ratio of single unit house, ratio of aged peoples' house ownerships, ratio of welfare recipients, ratio of old housing, and number of public healthcare facilities. Secondly, four factors are identified from factor analysis including aging factor, welfare factor, economic vitality factor, and new town factor. The aging level of a region is negatively related to the strong level of those factors. Thirdly, cluster analysis results in four different types of formal regions including rural mountainous coastal type, rural non-capital region type, large metropolitan type, and provincial industrial city type.

This Study is designed to present the concret data on the contents of the economic role and their change in the recent decade among women in a Korean Village. The Case Study method was used and the data was obtained through the participant observation. This Study is composed of the three parts. The first part deals with the effect of the agricultural mechanization upon the agricultural labor pattern of women. The second part examines how the introduction of a golf course and the textile factory in the vinicity affects the labor pattern among village women. The last part tries to demonstrate that the increasing contribution of women to the village economy has not yet produced any positive effect to their social status in the village. This is seen through the detailed description of two important village activities, one social(Tae dong-Gae) and the other ritual (Mokshinjae). The Results of the Study can be summarized as fallows. Firstly, the mechanization of farming is responsible for the increasing marginalization of women's labor in farming. This is particularly true for rice cultivation. Horticulture is still cultivated by women. As the mechanization progresses further, this trend will be more articulated. Secondly, it is found that women are actively utilizing the new external economic opportunities. In fact they are found to prefer those non-farming works to the traditional farming work. The former offers them less burdened work, less working hours, and more income than the letter. Lastly, women are found to be completely excluded from the process of the two important village activities. Only men are participants in them, and women only provides the labor for preparation of food and the necessary chores.

This study aimed to analyze characteristics and factors affecting of depression by households type of elderly with disabilities. Data were analyzed using chi-square test, logistic regression analyses according to the PSED. Data were 608 individuals. First, The one-person households group showed significantly female, non-capital, severe disorder, lower health status, lower economic level, higher help for daily life, higher experience of discrimination, lower satisfaction with relationship, lower participation in social activities. Second, Factors affecting depression included experience of discrimination, participation in social activities. Multi-person group included gender, occupied area, health status, economic level and one-person group were help for daily life. In order to reduce depression, it is necessary to reduce experience of discrimination, improve awareness of disability, health care, economic supports and so on. This study is meaningful in that it classifies households types. In the future, there is a need to longitudinal studies.

This study aims to investigate the factors affecting tooth loss and the association between smoking and tooth loss, by using the forth Korea National Health and National Examination Survey(2007-2009) of 1,565 elderly people over 65 years old. In terms of the characteristics, as age increases, tooth loss increases. In particular, according to the results of the analysis that identify the correlation between smoking to gender, socio-economic status and dental visiting patterns after correcting socio-economic factors and behavior, it is clear that male's tooth loss is higher than female's in current smoking and tooth loss is caused highly in the lower socio-economic status. In the dental visiting patterns, tooth loss is high when visiting more than twice a year. Therefore, it seems to need a preventive non-smoking policy at the level of dental services through further studies.

This paper attempts to find out the economic roots of the increasing tendency not to choose the science and engineering (S&E) fields in the colleges. The analysis shows that the relative economic position of the S&E graduates measured in terms of employment quality is not significantly different from that of the non-S&E graduates. But the S&E graduates earn relatively low wage and self-employment income. Furthermore, the relative income of the top 5% bracket of the S&E graduates has been declining in the recent five years. The paper concludes that low relative income of the average S&E graduates as well as the increasingly lower relative income of the most able S&E personnel, coupled with the increasing compensating differential required for the S&E jobs, is the main reason for the 'avoidance' phenomenon of the S&E fields.

This study was conducted to evaluating the willingness to pay for marine leisure ships through a contingent valuation method that can estimate the value of non-market economy. The questionnaire adopted a double-bound dichotomous choice Model and the variables for evaluating the amount of willingness to pay consisted of demographic variables and respondent behavior variables, and related information verified through previous studies. As a result of collecting and analyzing a total of 309 questionnaires, the amount of willingness to pay for marine leisure ships was estimated to be 25,510 won. In addition, significant variables affecting the amount of willingness to pay were the experience of visiting the island, satisfaction with the introduction of new maritime transportation, and intention to revisit the island. Through this study, it can be used as a basis for evaluating the economic value of new maritime transportation by estimating the willingness to pay for marine leisure ships using the contingent valuation method.
