Republic of Korea officially announced its mid term reduction target which reduce about 30% of BAU GHG emission by 2020 in the 15th meeting of UNFCCC(COP 15) held in Copenhagen, Denmark 2009. To achieve this goal, it is necessary to understand the serious of climate change and take part in GHG reduction not only industry but also the nation. However, such positive participation in green life which may cause inconvenient of the life of the people. It should be accomplished with providing reliable information. This study suggests the scientific potentialities of GHG emission by guideline on low carbon life and green life to form and change a lifestyle suitable for coping with climate change. And also, this study quantitate the GHG reduction which may reduce demand for air conditioning by cool biz and warm biz. In Korea, this campaign has become known as 'CoolMaebsi' by Ministry of Environmental of Korea. 'CoolMaebsi' is a compound word of 'Cool' which means feel refreshed, and 'Maebsi' is a Korean word which means attire. Though this campaign is effective and significant to reduce the GHG emission yet there were no study on quantitative analysis. Therefore this study calculated reduced energy consumption and potential GHG emission by measuring variation of skin temperature. As the result, wearing warm biz and cool biz have an effect of reducing not only the energy consumption but also GHG emission. To achieve the low carbon society, it is necessary to improve the energy saving system and introduce the policy which guide to change a life style.

Purpose: The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. Methods: Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017-2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. Results: The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B₁, niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents' physical activity increased. Conclusion: The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.

Purpose: The aim of this study was to investigate the feeding patterns, use of dietary supplements, and nutrient intake of Korean toddlers. Methods: We used data for 930 toddlers who participated in the 4th Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2009. Feeding patterns and use of dietary supplements were assessed using standardized questionnaires, and nutrition intake was assessed using the 24 hr recall method. Results: In 2007~2009, 48.7% of toddlers used dietary supplements. Most parents (95.4%) initiated a regime of dietary supplements for their children following the advice of friends or relatives. Only 0.4% of parents followed the advice given by their doctors for dietary supplements use. In the survey of nutrient intake for toddlers, the prevalence of inadequate calcium intake was 53.9% for subjects aged 1 year, 55.2% for 2 years and 65.6% for subjects aged 3 years. The prevalence of inadequate iron intake was 52.0% for subjects aged 1 year, 48.7% for 2 years and 48.4% for subjects aged 3 years. In the survey performed on feeding patterns of toddlers during the infant period, mixed feeding accounted for 57.4%, breast feeding for 32.2%,and formula feeding for 10.4%. Sixty-five percent of toddlers began weaning between 4 and 6 months. Conclusions: This study indicated that a number of toddlers were at risk of inadequate calcium and iron intake. The role of professionals in counseling for qualified dietary intake and dietary supplement use is therefore necessary for Korean toddlers.

Si is a genre which has been steadily loved by Korean, Particularly, 1920's through 1930's, the Revival Movement of Sijo is made by the school of Literary for People, including Choi Namseon, Lee Byeonggi and Lee Eunsang. And Kwon Goohyeon, a member of KAPF, and Han Yongwoon, not belonging to any literary group were interested in Sijo. Kwon Goohyeon, both a member of KAPF and an anarchist has published A Present of Black Room(1927), which is one of the two published in 1920's-1920's saw only two volumes of Sijo works be published: Choi Namseon's 108 Agony(1926) and Kwon's. However, Kwon Goohyeon's work has not been illuminated. compared with Choi Namseon's and the Revival Movement Sijo by the school of Literary for People. It is because Korean literary world has been under the anti-communism ideology since the Liberation of Korea. However, it caused to explore proletarianism Sijo (Joh woon) and proletarianism poetry (Park Yeonghee) that Kwon is a memeber of KAPF and an anarchist. Han Yongwoon, not belonging to any literary group, was very famous as the poet of My Belolved One's Silence(1926), not as a Sijo poet. It means that he s not been illuminated as a Sijo poet. However, his Sijo is enough to contain his various features such as a man of Independence Movement, a Buddhist monk, a lyrical poet and so on. His first Sijo is For Planting Mookoonghwa-Poetry Written in Prison(1922), which has been published four years prior to My Beloved One's. And his affection on Sijo is inferred from the fact that he has constantly published Sijo more than free verse. The aim this thesis is to find out a position of Sijo 1920's through 1930's from a study on Kwon Goohyeon's and Han Yongwoon's Sijo. Sijo, Korean traditional literary genre, was written by most of the poets including not only the school of Literary for People but Kwon Goohyeon and Han Yongwoon 1920's through 1930's. As a result, the writing of Sijo was not a partial movement by the anti-KAPF group, but by a paradigm in 1920's through 1930's.

Objectives: This study is to investigate the prevalence and related factors of metabolic syndrome among Korean adults aged 20 years and above. Methods: From the database of the $5^{th}$ Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2010, data of 5,670 adults who responded to all the questionnaires of health interview and had metabolic syndrome in the health examination were included in this analysis. SAS 9.2 was used for statistical analysis with complex sample survey modules and commands. Results: The prevalence rate of metabolic syndrome based on the criteria proposed by International Diabetes Federation (IDF) was 18.8%. The prevalence of metabolic syndrome in each group was: 20.7% of women, 43.1% among elderly over 70 years old, 40.6% of the divorced or the separated, 27.6% of recipients of economic support from the government, 23.6% of people who had alcohol dependency problem, and 43.7% of overweight or obese adults. Independent risk factors based on the multiple logistic regression analysis revealed that prevalence of metabolic syndrome was associated with female (odds ratio 1.59 [95% confidence interval 1.20-2.11]), age (50s 3.95 [2.11-7.37], 60s 5.62 [2.98-10.61], 70s 10.56 [5.25-21.25]), high school education (0.52 [0.37-0.74]), clerk occupation (2.14 [1.27-3.60]), divorced marital status (1.72 [1.15-2.59]), alcohol dependency (1.86 [1.16-2.98]), higher BMI (14.08 [10.60-18.70]). Conclusions: The metabolic syndrome is prevalent among Korean adult population according to IDF criteria. Several demographic characteristics and potentially modifiable factors are associated with metabolic syndrome. Identification of this high-risk group and management of these modifiable factors are warranted to reduce the prevalence of metabolic syndrome.

In this paper, the main subjects with which I deal are as follows: (1) Is Distancing Philosophy from the real ruling power a way of practical-philosophical resistance, based on social reformation as a axiological directivity of Kim Tae-Gil's ethical thought, though it is negative type of resistance? Or is it a sort of transformed value-free opportunist behavior which allows antidemocratic ruling group to coerce the people into submission, assuming an uncompromising stand seemingly? (2) Is Kim's defense argument on the opening of the course of National Ethics and the all-out activation of National Ethics education under Park's Yushin Regime derived from his own philosophical belief? Or is it brought out from the external conditions and circumstances surrounding Kim Tae-Gil which forces him to participate in the national undertaking for the settlement of the course of National Ethics in the university? The 'provisional' answers about the two subjects are as follows: (1) Kim's Distancing Philosophy is a type of practical philosophical revolt against the dictatorship power under Yushin Regime, though it is negative form of resistance. We can accept this philosophical elucidation above all by confirming the fact that the reform of reality is the main ethical trait running through his entire ethical thought system. However distancing philosophy disclose the crucial limits to allow itself to boil to the philosophical practice compromising with real ruling power eventually, though it is intended upon its own social ethical directivity and conviction. (2) The primary factor which affects Kim to propose such an advocation argument on the course of National Ethics and the education of National Ethics is the external conditions and circumstances surrounding him, especially the power-relation between he and ruling group and intimate human relation between he and his superior philosophers who carries out the role of a ideologue for the Yushin Regime, rather than his own philosophical belief. But no matter what primary factor, Kim's action to make a advocating argument to support the course and the education of National Ethics is to blame, on that account that he cannot adequately his social responsibility and role given to him as a reformist moral philosopher who will pursue the realization of righteous democratic society. Along with that, It is not too enough to criticize him sharply for such defending action. The reason is that his supporting stance for National Ethics education is brought out, by not adhering closely to the philosophical way of distancing from the dictatorial power devoid of political legitimacy and moral justification.

Purpose: Management of the metabolic risk factors in diabetes patients is essential for preventing or delaying diabetic complications. This study compared the levels of the metabolic risk factors in diabetes patients according to the income levels, and examined the secular trends in recent decades. Methods: The data from the Korea National Health and Nutrition Examination Survey 1998 ~ 2014 were used. The diabetes patients were divided into three groups based on their household income levels. General information was obtained through self-administered questionnaires, and the blood biomarkers and blood pressure data were obtained from a health examination. Multivariable linear regression models were used to compare the metabolic biomarker levels according to the household income levels, adjusting for potential confounding factors. Results: The fasting blood glucose, hemoglobin A1c, and blood lipid (total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride) levels were similar in the three groups. During the survey period of 16 years, the blood pressure showed a significant decreasing trend with time in all groups (p < 0.001). In contrast, the fasting blood glucose (p = 0.004), total cholesterol (p < 0.001), and LDL-cholesterol levels (p = 0.007) decreased significantly, and the HDL-cholesterol level (p < 0.001) increased significantly in the highest-income groups. In the lowest-income group, the fasting blood glucose (p = 0.02), total cholesterol (p < 0.001), and triglyceride (p = 0.003) levels showed a significant decreasing trend over time. On the other hand, the middle-income group showed no significant change in any of the metabolic risk factors except for blood pressure. Conclusion: The level of management of metabolic risk factors according to the income level of Korean diabetes patients was similar. On the other hand, the highest- and lowest-income groups showed positive trends of management of these factors during 16 years of observation, whereas the middle-income group did not show any improvement.

Purpose: This study sought to predict the reasons for skipping breakfast by adolescents aged 13-18 years using the 7^th Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The participants included 1,024 adolescents. The data were analyzed using a complex-sample t-test, the Rao Scott χ²-test, and the classification and regression tree (CART) algorithm for decision tree analysis with SPSS v. 27.0. The participants were divided into two groups, one regularly eating breakfast and the other skipping it. Results: A total of 579 and 445 study participants were found to be breakfast consumers and breakfast skippers respectively. Breakfast consumers were significantly younger than those who skipped breakfast. In addition, breakfast consumers had a significantly higher frequency of eating dinner, had been taught about nutrition, and had a lower frequency of eating out. The breakfast skippers did so to lose weight. Children who skipped breakfast consumed less energy, carbohydrates, proteins, fats, fiber, cholesterol, vitamin C, vitamin A, calcium, vitamin B1, vitamin B2, phosphorus, sodium, iron, potassium, and niacin than those who consumed breakfast. The best predictor of skipping breakfast was identifying adolescents who sought to control their weight by not eating meals. Other participants who had low and middle-low household incomes, ate dinner 3-4 times a week, were more than 14.5 years old, and ate out once a day showed a higher frequency of skipping breakfast. Conclusion: Based on these results, nutrition education targeted at losing weight correctly and emphasizing the importance of breakfast, especially for adolescents, is required. Moreover, nutrition educators should consider designing and implementing specific action plans to encourage adolescents to improve their breakfast-eating practices by also eating dinner regularly and reducing eating out.

This study was conducted to evaluate vitamin D intake of Koreans in a total diet study (TDS) and to determine the effect of irradiation on vitamin D synthesis in mushrooms. For analysis, sample were saponified and extracted with hexane, and vitamin D was quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Based on the validation results, the recovery of the National Institute of Standards and Technology (NIST) standard reference sample (SRM) 1849a was 96.7% and the z-score of -1.6 was obtained by the Food Analysis Performance Assessment Scheme (FAPAS) proficiency test (PT) 21115. Vitamin D₂ was not detected in any samples, and the highest level of vitamin D₃ was detected in mackerel and anchovies ranging from 24.2 to 120.2 ㎍/kg. The mean daily intake of vitamin D was 0.99 ㎍/day, as estimated from the vitamin D contents of the analyzed foods and their corresponding intake. The adequate intake (AI) of vitamin D based on the Dietary reference intakes for Koreans provided by the Ministry of Health and Welfare is 5-15 ㎍/day for Koreans aged 6 to 75 years. Compared with this AI, vitamin D intake of Koreans estimated in this study was inadequate. For that, the increased vitamin D content in ultraviolet (UV)/sun light irradiated mushrooms warrants further research to increase vitamin D intake of Koreans through diet.

Purpose: This study examined the impact of adolescents' dietary behavior on their quality of life using the nutrition quotient for adolescents (NQ-A) for some high school students in Seoul. Methods: The subjects were 176 high school students living in Seoul. The NQ-A was used to assess the dietary quality, and the quality of life was assessed by categorizing it into life satisfaction, environment, health, participation and safety, leisure activities, and emotional factors using survey questions validated through previous studies. Results: The NQ score of the survey subjects was 49.30 points. Based on the NQ scores, 7.4%, 46.6%, and 46.0% of participants were categorized as the 'high', 'medium', and 'low' groups, respectively. The total NQ score and balance, diversity, and practice factor scores were positively correlated with life satisfaction, environment, health, participation and safety, and leisure activities among the quality of life subscales. Regression analysis showed that the total NQ score was positively associated with life satisfaction, health, leisure activities, and emotions; the moderation factor was negatively associated with life satisfaction and health. The balance factor was positively associated with the environmental factor. The practice factor was positively associated with health, leisure activities, and emotions, and the environment factor was negatively associated with emotions. Conclusion: These results show that adolescents' quality of life is closely related to their diet, so it is necessary to maintain a balanced and varied food intake and desirable eating behaviors to improve adolescents' quality of life. Furthermore, adolescents' quality of life is influenced by other factors. Therefore, further research is needed to assess the quality of life, including dietary factors, as well as physical, emotional, psychological, and social development.
