To accomplish the greenhouse gas reduction which is over core unit project of the "Green growth" policy and "Resource circulation society", it is important to maintain proper balance and complement between energy recovery from waste and material recycling. This research(study) examined the related policies on the past of korea and foreign country, and also "The 4th resource recycling master plan" and "Energy recovery from waste plan" to provide advisable direction for resource recycling policy. The results of the research(study) showed that there were no significant difference between korea and developed foreign countries waste management policies. But in German policy, energy recovery from waste and pre-treatment are importantly considered and highly required for permission. Under current circumstance in korea, recycling will be more difficult than in the past. According to "The 4th resource recycling master plan", film type of synthetic resin was not sustainable recycled material in substance."Energy recovery from waste plan", proved that the energy recovery from RDF/RPF have lower efficiency than regular incineration generation and substance recycling. To solve these problems, the energy and remainder heat recovery must be generalized to "Energy recovery" concept and institutional improvement such as LCA(Life Cycle Assessment) system are need to support it. And also technology development to extract synthetic polymer by dissolved film type of synthetic resin must be provided.

Occurrence of malodor could cause adverse impacts on human health and increase public interest. Therefore, scientific methods to decrease odor is required. Endeavor to decrease odor from compost however has not fully been successful. The purpose of this research is assessment of some amendments to reduce $NH_3$ from immature composts. Calcium hydroxide was applied to composts due to it's characteristics to increase pH. Activated carbon and zerovalent iron (ZVI) were selected because of their adsorption properties. The research results were as follows: Calcium hydroxide, activated carbon, zerovalent iron increased the composting temperature above $60^{\circ}C$. The addition of calcium hydroxide, activated carbon, and ZVI to compastry process increased pH 8.6 - 8.8 from $1^{st}$ day to $14^{th}$ day. During the 14 days of composting, addition of calcium hydroxide, activated carbon and ZVI changed EC from $2.15-0.66dS\;m^{-1}$, $1.48-1.11dS\;m^{-1}$, respectively and $1.77-0.68dS\;m^{-1}$. The difference in EC of the compost was due to irregularities of samples. Organic matter in the compost decreased through out theexcept control. The $NH_4-N/NO_3-N$ ratio of all experimental compost increased through the process. The addition of activated carbon, calcium hydroxide and ZVI decreased $NH_3$ from 0.1ppm, 0.7ppm and 1.7ppm more than the control (pig manure and sawdust), 9.3ppm, in 30 days of composting. In conclusion, odor from prematured compost decreased by addition of chemicals like calcium hydroxide, activated carbon, zerovalent iron. Moreover, use of these $NH_3$ reducers alone or together combined at different periods of composting etc. could decrease $NH_3$.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

Since the Syrian Civil War in 2011, the number of refugees has been on the rise in Korea as well as worldwide. In addition to recognition of legal status for refugees, employment and education support, and qualification recognition are emerging as social issues. In this context, this study aims to compare the cases of Netherlands and Norway in terms of evaluation and recognition of refugees' qualifications. The findings of the study show that although there were concerns about the lack of official documents to verify the qualifications of refugees, the two countries have developed a special process for the evaluation and recognition for refugees respectively according to the Lisbon Recognition Convention. In addition, both countries have developed a recognition of prior learning system which has made the qualification recognition process flexible from a point of refugees. These experiences could be used as benchmarks for the Korean government which has a responsibility to develop its own qualification recognition system for refugees in the near future.

This study aims at investigating the psychosocial factors that influence on the intake of fruits and vegetables according to stage of change in rural children. Total 256 elementary school children, located in Yeongi-Gun, Chungnam-Do were surveyed from May 14 2007 to May 30 2007. Stage of change on the intake of fruits and vegetables of the students was categorized into three stages: precontemplation (PC), contemplation & preparation (CO&PR) and action (AC). Psychosocial factors consist of decisional balance based on pros and cons, process of change of cognitive and behavioral processes, and self-efficacy. The recognition of cons out of decisional balance showed the highest score in the subjects at the stage of PC and lowest score in those action stage. While, no difference was shown in the score of recognition of pros among the stages. Both levels of cognitive and behavioral process of change showed no difference between two pre-action stages, PC and CO&PR. However, the subjects of action stages got higher scores in more number of the variables in both of cognitive and behavioral process of change compared to those of pre-action stages with more remarkable in results vegetables than in fruits. The results of self-efficacy on fruits and vegetables intake showed that the higher stages of change, the higher the self-efficacy score. From the result, it is suggested that the items and level of psychosocial factors are different according to the stage of change and between fruits and vegetables in rural children.

This study was carried out to investigate health status and nutritional status based on dietary intake and food habit of elderly women in rural area of Keyonggi Province. The subject of this study were 133 elderly women aged 60 and over and interviewed with a questionaire. Main result was as follows : 1) Health score based on modified Cornell Medical Index, CMI(45 out of 195 items) was the average $29.1\pm6.8$ and was not significantly different with family size educational level and farmwork participation. In age, 44.0% of the subject in 60~65 years old was low score of CMI(11~25), but 50% of the subject in older than 80 years old was high score(33~44). The subject with disease was 82% and disease of musculoskeletal system was main type. 2) Dietary intake data obtained by a semiquantitative food frequency questionaire showed the average daily intake of energy, protein, Ca, retinol and riboflavin was lower than RDA Daily energy, protein and Ca intake was individually 84%, 67% and 55.1%. It was retinol that was the least sufficient as 49.1% of RDA. 3) The relation between CMI score(divided into three level : low, middle and high) showed low level was significantly different with others according to daily intake of energy, protein, retinol, thiamin, riboflavin and ascorbic acid. The correlation between CMI score and all nutrient intake were highly significant (p＜0.001), thus we knew that health status was affected importantly by nutrient intake. 4) Family size, educational level and age showed not significant correlation with all nutrient intake. 5) In food habit, 84.8% of the subject had regular mealtime and 14.4% were skip meal sometimes. The main reason of skip meal was a poor appetite. Preference for salty taste of subject was insufficiently salty of somewhat salty. Preference for fishes and meats showed the subject consumed fishes more than meats, but 23.5% of the subject didn't consume both. The subject eaten supplement was 38.3%.
