This study aims to investigate and practically examine the effect of environmental qualifications based on the theoretical background on the area. On the basis of theoretical background, a study model was formulated in a way that the effect of qualifications in enterprises side is divided into an economic effect (improvement of productivity, improvement of qualifies of products) and non-economic effect (credibility on the job, expertise on techniques, assessment criteria on entrepreneurial value, applicability of job arrangement). Then, survey was carried out with questions designed in accordance with this model. The hypotheses were proved as the following. First, fir hypothesis 1(Environmental qualifications will bring up positive impacts on the economic effect of enterprises), it turned out to be true. The improvement of productivity and qualities of products were chose to represent the economic effect of entrepreneurs, and the both factors appeared to have positive impacts on the economic effect of enterprises. Second, for hypothesis 2(Environmental qualifications will have positive impacts on the non-economic effect of enterprises), it turned out to be true. Environmental qualifications were proved to have positive impacts on credibility on the job, expertise on techniques, assessment criteria on entrepreneurial value, applicability of job arrangement, which were introduced to represent the non-economic effect of enterprises. In conclusion, environmental qualifications were proved to have positive impacts on both economic and non-economic effect of enterprises.

As the environmental impacts of fossil fuel energy sources increase, the South Korean government has tried to change non-environmental-friendly enery sources to environmental-friendly energy sources in order to mitigate environmental effects, which lead to global warming and air pollution. With both a limited budget and limited time, it is essential to accurately evaluate the economic and environmental effects of renewable energy projects for the efficient and effective operation of renewable energy plants. Although the traditional economic evaluation methods are not ideal for evaluating the economic impacts of renewable energy projects, they can still be used for this purpose. Renewable energy projects involve many risks due to various uncertainties. For this reason, this study utilizes a real option method, the Geske compound model, to evaluate the renewable energy projects on Jeju Island in terms of economic and environmental values. This study has developed an economic evaluation model based on the Geske compound model to investigate the influences of flexibility and uncertainty factors on the evaluation process. This study further conducts a sensitivity analysis to examine how two uncertainty factors (namely, investment cost and wind energy production) influence the economic and environmental value of renewable energy projects.

This study analyzes the effects of trade globalization and financial globalization on consumption classified by type(durable, quasi-durable, non-durable and service). On the other hand, trade globalization and financial globalization were decomposed into OECD common factor, regional factors, and the idiosyncratic country-specific factors by time-varying dynamic factor analysis. The characteristics of OECD common factor, regional factors, and the idiosyncratic country-specific factors of trade and financial globalization were analyzed. Furthermore, the influences of these factors on consumption by type were analyzed. The analysis shows that globalization has negative effects on consumption. In particular, we found out that the idiosyncratic country-specific factor of Korea in trade and financial globalization had a statistically significant negative effect on consumption. We can infer that the globalization affecting consumption can be attributed to the idiosyncratic country-specific factor, which is economic choice rather than uncontrollable global trend. Accordingly, to solve the sluggish consumption problem caused by globalization, it is necessary to require not only domestic consumption expansion policies but also the efforts to resolve economic polarization problems to be able to stimulate consumption.

This paper analyse current interpretation of the "causal link" that in particular, focuses principally on the so-called "non-attribution" requirement of Article 4.2(b) of the Safeguards Agreement. The safeguard measures are justified as a temporary economic adjustment to harm that is caused by an increase in imports. The problem with this justification is that there are other kinds of economic forces that may injure domestic industries, such as changes in consumer tastes, government spending or a lack thereof, and economic downturns. These problems do not justify government-imposed remedies. When factors therefore other than increased imports are causing injury to the domestic industry at the same time, such injury shall not be attributed to increased imports. The Appellate Body stressed that a contribution of third-party imports to the existence of serious injury must be sufficiently clear as to establish the existence of the causal link required, it found that Article 4.2(b) does not suggest that increased imports be the sole cause of the serious injury, or that other factors causing injury must be excluded from the determination of serious injury. The interest in separation is to ensure that a measure is not applied to remedy harm not caused by imports, but this basic point assumes that the harm is distinguishable in the first place. It also assumes that the safeguard is designed to respond to harm caused by imports. In fact safeguards were never intended to respond to this kind of unfair trade, but rather to provide whatever emergency relief might assist an ailing domestic industry if imports happened to be a part of that injury. The Appellate Body's insistence in breaking cause and effect down to minutia in the non-attribution analysis seems to be so overly intricate that it conflicts with it's broader focus on evaluating factors that effect harm on the industry as a whole.

Objectives: The purpose of this study is to identify the associated factors with subjective oral symptoms experience of obesity adolescents. Methods: The study subjects were targeting 8,139 obesity adolescents and 55,601 non-Obesity adolescents who completed 2016 Korean Youth Risk Behavior Web-based survey. Dependent variables were subjective oral symptoms experiences of fracture teeth, pain, throbbing pain, periodontal pain & bleeding, mucosal disease and bad breath. Independent variables were demographic characteristics of the subjects, oral health behaviors, health behaviors and eating habits. Results: Obesity adolescents were 12.8% with 61.9% subjective oral symptoms experience. Regarding the related factors of subjective oral symptoms experience of obesity adolescents, the factors were identified to be significantly higher in high school (OR=1.72) compared to middle school, learning achievement was higher in middle (OR=1.09) and lower (OR=1.31) compared to high, economic status was higher in lower (OR=1.09) compared to high, sealant experience (OR=1.10) and scaling experiences (OR=1.12) responded no were higher compared to responded yes, smoking experiences responded yes(OR=1.08) were higher compared to responded no, sweet drink (OR=1.14) and fastfood (OR=1.13) consumption were higher in consumption compared to non-consumption and females (OR=0.46) were higher than males. Oral symptoms experience were lower that father and mother's level of education were under high school graduation (OR=0.86) compared to unknown, economic status was in case of middle (OR=0.93) compared to high, tooth brushing was lower in under 1 time (OR=0.76), 2 times (OR=0.61) compared to more than 3 times, vigorous physical activities responded no (OR=0.75) were lower, compared to yes, vegetable consumption was lower in non-consumption (OR=0.68) compared to consumption. Conclusions: Subjective oral symptoms experiences were identified higher in obesity adolescents than non-obesity adolescents. It would be useful to use the results of this study to reduce oral symptoms and necessary to develop a program system considering characteristics of obesity adolescents.

Objectives: The objective of the study was to investigate the factors related to non-use of interdental care products (ICP) in adolescents. Methods: The 2019 Korean Youth Risk Behavior Web-based Survey was used, examining 57,303 subjects. Complex-sample chi-square test and logistic regression analyses were performed to identify differences in ICP according to sociodemographic characteristics and oral health behavior and to determine the factors related to non-use. Results: The ICP non-use rate was 70.9%. Factors related to the non-use of ICP were middle or low economic status (OR=1.367 and 1.677). The other significant variables were less than one tooth brushing per day (OR=1.542), no scaling within 12 months (OR=1.631), and receiving dental treatment either once or two times or more (OR=1.757 and 2.195). Conclusions: To increase the ICP usage rate, continuous attention is needed from schools and families in addition to interventions at the national level.

The purpose of this study was to determine what factors influence various non-marriage types by considering reasons why adults are not married. The roles of individual characters and family values affecting each type of non-marriage were carefully considered. From the data of 'the Survey on the National Fertility, Family Health and Welfare in Korea in 2015', 1,053 unmarried adults who were in their late 20s to middle 40s were selected. Results show that non-marriage types among unmarried adults were diverse. Depending on sex, the distribution of non-marriage types differed. While economic reasons were predominant among men, lack of opportunities for marriage was the main reason for most women who were not married. Findings also suggest that factors such as socio-demographic characters and family values were differentially associated with each non-marriage type. These findings indicate a great deal of diversity in needs, lifestyle, and life satisfaction among unmarried young adults. This suggests that an increase in the population of unmarried adults can be related to prospectively various marriage behaviors and family patterns in our society in the future, and consequently life patterns will be different among the adult generation.

Objectives: As the size of elderly population living alone grows, socioeconomic diversity has also increased. This study examined if social risk factors of poor self-rated health were distinguishable between the low income elderly and their non-low income counterparts both living alone. Methods: The '2006 Elderly Health Interview Survey' conducted by D-gu in Seoul was utilized. We divided the elderly living alone into two groups depending on their economic status: low income and non-low income. Employing logistic regression, we analyzed the associations of poor self-rated health with socio-demographic factors, health-related factors, social support, the relations with children, social activities, welfare service use, and the perception of neighborhood safety. Results: Proportion of rating one's own health being poor was different between two populations. Social support was important for the self-rated health of the non-low income elderly, while welfare service use, the perception of neighborhood safety, and the relations with children were noticeable for the low income elderly. Conclusions: To better understand the health need of elderly population living alone, their heterogeneity in socioeconomic characteristics should be taken into account.

The purpose of this study was elderly women with disabilities to increase life satisfaction from the recognition that were original goals. Factors affecting life satisfaction confirm, and in influencing aging affects looked ready. In the case of non-disabled people was life satisfaction showed a link between preparation for the later life. Expected life satisfaction of elderly women with disabilities were equally applicable whether verification was carried out. The results of this study were as follows: First, the difference in life satisfaction according to demographic factors, psychological factors, health factors, economic factors, social factors were all of the factors in the elderly group of women with disabilities in accordance with the life satisfaction were different. Second, the factors that influence the life satisfaction for the elderly women with disabilities were psychological factors, health factors, economic factors, social factors and demographic factors. Third, in relation to independent variable and dependent variable, preparation for the later life factor was found operating as moderation variable in relations between level of economic status, chronic diseases. Based on this results, the implications for future studies on women with disabilities were discussed.
