  • We are to introduce an example of ESD in connection with SDGs through liberal arts courses opened at the College of Education. We analyzed the awareness of the carbon footprint expressed by 42 preservice teachers in a class designed in connection with SDGs 13 goal, 'climate action'. The pre-service teachers wrote a carbon diet diary, a checklist for the level of practice that emits carbon in daily life, and freely expressed the source and proportion of their carbon emissions through the carbon footprint drawing activity. In items of electricity use, public transportation use, and garbage disposal, the level of practice was positive, but water use was analyzed in a negative way. The pre-service teachers who expressed the carbon footprint in 2-3 items reached a majority, showing limitations in recognizing the carbon emission situation in their daily life. Pre-service teachers will be the main actors of education on the environmental issues of the earth at the school site, and the carbon literacy of pre-service teachers will directly or indirectly affect students. We hope that various ESD programs linked to the 17 SDGs will be developed and applied to the educational field to contribute to sustainable global environmental education.

  • The effects of the processing mixture of pig manure and various organic wastes on the growth, cast production of earthworm, and conversion of organic matter to earthworm tissues by vermicomposting. The substances used in this experiments were sawdust, rice hull, coffee waste, brewery waste, litters, turfgrass cutting residues, rice bran, vegetable wastes and rice straw and were mixed with pig manure at a ratios of 50:50 (v/v), and pig manure 100% (control), respectively. The highest values of growth parameters, cast production and conversion efficiency of organic matter to earthworm tissues were obtained at the mixtures of pig manure with coffee waste, it may due to the favourable diet conditions to process with pig manure by vermicomposting. But, all of the earthworm died in the pig manure 100% (control) and pig manure with vegetable wastes treatments by vermicomposting was impossible in this experiment. The vermicast contained a higher values of total nitrogen, available phosphorus, exchangeable cations and cation exchange capacity than their parent materials with increased availability of nutrients and improved physicochemical properties.

  • Consumers' growing interest in the environment has recently led them to recognize the importance of their dietary life and sustainable consumption. Thus, there is an increasing necessity to identify consumers' response on the relationship between the consumption of functional food and their interest in helping environment. This research was conducted to analyze consumers' behaviors as related to Spirulina, an eco-friendly functional food brand, by subdividing markets according to consumers' food lifestyle. The results showed that consumers were categorized into 3 types (high involvement in diet, pursuit of safety in diet, and pursuit of convenience in diet), and there was a significant difference in the consumption behaviors of the functional food according to the 3 types. Their positive attitude towards functional food and interest in the environment led to changes of their actual purchasing behavior by increased purchase of Spirulina. Also, consumers who displayed high environmental involvement showed a more favorable attitude towards functional food. Therefore, to expand the market of eco-friendly functional food, it is necessary to subdivide the market and target the consumers who are highly involved with protecting the environment, and to execute marketing strategies for eco-friendly products, in order to increase the consumers' awareness about eco-friendly functional food.

  • Objectives : The purpose of this study was to examine the general characteristics, oral health knowledge and oral health behavior of elderly people and the relationship of their oral health knowledge to practice of the knowledge in an attempt to provide information on the development of the senior oral health care system. Methods : The subjects in this study were 324 elderly people who used five different social welfare centers in the regions of Sooncheon and Yeosoo. Results : 1. The oral health knowledge of the elderly people investigated was at a low level. Among different sorts of oral health knowledge, they had the best knowledge on the cause of dental caries, and they were most ignorant about the right time for regular dental checkup. 2. Regarding connections between general characteristics and oral health knowledge, the elderly people who never went to a dentist had a better knowledge on oral health, and those who cared about oral health had a better knowledge than the others who didn't. 3. As to practice of oral health knowledge, the best oral health behavior they did was to clean the tongue during toothbrushing, and oral health behavior was not to have an unbalanced diet. The second best one was to be well-nourished, and the third best one was to refrain from drinking, smoking and eating sugar-containing food. The fourth best one was to get a regular dental check-up and teeth cleaned. 4. There was a positive correlation between oral health knowledge and oral health behavior. A better oral health knowledge led to a better oral health behavior. Conclusions : The better oral health knowledge of the elderly people was followed by a better oral health behavior, and the development and implementation of customized oral health education programs geared toward the elderly are urgently required. Oral health professionals should direct their energy into providing sustainable and systematic oral health education, and institutional measures should be taken to make it happen.

  • Environmental issues resulting from climate change and energy crises have become global issues, and cycling has gained greater popularity for sustainable transportation. Though many cities are trying to build bicycle roads, it is not easy to implement bicycle roads because there is little available space for bicycle facilities. Therefore, road diets have become more popular in Korea. However, there has been no intensive research to date of their impacts. The purpose of this research is to evaluate the effects of road diets and construction of bike lanes. Every benefit, including energy benefit, environmental benefit, and health benefit is considered, while only time savings benefit has been considered in previous studies. The benefit analysis for the Seoul metropolitan area as a case study shows that road diets have a (1) time saving benefit for only five percent of the mode share and (2) enough total benefit even if bicycle mode share is less than two percent.

  • Trout production is a growing activity in recent years but requires new alternative sources of feed to be sustainable over time. The objective of this research was to determine the apparent digestibility coefficient (ADC) of dry matter (DM), organic matter (OM), crude protein (CP) and digestible energy (DE) of $ka{\tilde{n}}iwa$ (Chenopodium pallidicaule Aellen), kiwicha (Amaranthus caudatus L), quinoa (Chenopodium quinoa Willd), beans (Phaseolus vulgaris L.), sacha inchi, (Plukenetia volubilis L) and jumbo squid (Dosidicus gigas) meal in juvenile rainbow trout. The experimental diets were composed of a 70% basal diet and 30% of any raw materials. The ADC was determined by the indirect method using insoluble ash as a non-digestible marker. Jumbo squid, sacha inchi and quinoa showed the highest values of ADC (%) of DM (84.5, 73.5 and 69.7), OM (89.1, 78.4 and 72.9), CP (93.2, 98.0 and 90.3), and DE (4.57, 4.15 and 2.95 Mcal/kg DM), respectively. The ADC values for $ka{\tilde{n}}iwa$, kiwicha and bean were significantly lower. In conclusion, quinoa meal and jumbo squid meal have an acceptable digestibility but sacha inchi meal is a potential alternative for rainbow trout feeding in the future.

  • Hanwoo cattle have been genetically selected for enhancing meat quality and meat quantity since the last few decades. Beef consumption in South Korea has also increased to 11.6 kg per year in 2016 and is expected to continue to increase. For improving meat quality, Hanwoo cattle has been raised a high-energy corn-based diet for long fattening periods, which causes not increment of fat percentage in the loin muscle but increment of feeding costs. Consumer demands on the Korean beef industry are driving differing beef production systems and also changes to the beef grading system. For a sustainable Hanwoo industry, researcher in Korea have attempted to develop feeds for efficient fattening periods and precision feeding systems based on genetic information for Hanwoo cattle. Therefore, representatives of government, academics, and market association need to provide efficient collaboration for the future prospective or develop a precise management system for Hanwoo industry in Korea.

  • BACKGROUND/OBJECTIVES: Increasing the consumption of vegetables and fruits in Mexico remains a challenge. Promoting sustainable food production systems through schools may be an effective way to educate young people about food and nutrition issues. A study of nutritional education in adolescents, based on the school garden, is necessary in order to evaluate its effects on the consumption of fruits and vegetables among middle- and upper-income segments of the population. The objective of this study was to evaluate the effect of an educational intervention, accompanied by a school garden as an educational teaching tool, to improve vegetable and fruit consumption by Mexican teenagers attending a private middle/high school. SUBJECTS/METHODS: Teenagers between 12 and 18 years of age (n = 126) attending a private middle/high school in Queretaro, Mexico participated in a 3-arm, controlled, comparative impact study using a vegetable and fruit consumption frequency questionnaire, food consumption diaries, a psychosocial factor assessment questionnaire of vegetable and fruit consumption, and structured interviews. The participants were randomized into 3 experimental groups: 1) food education + school garden (FE + SG), 2) FE only, and 3) control group (CG). RESULTS: The FE + SG and FE groups significantly increased the frequency and daily intake of vegetables and fruits compared to the CG. The FE + SG group showed greater understanding of, reflection upon, and analysis of the information they received about vegetable and fruit consumption, as well as a greater willingness to include these in their daily diet. CONCLUSIONS: FE accompanied by a SG as a teaching tool is more effective at promoting vegetable and fruit consumption than either education alone or control in teenagers in middle-upper income segments of the population.

  • Objectives: This study examined the perception of the vegan trend of millennials and their future needs. Methods: This study was conducted online from June 21, 2021, to July 15, 2021, targeting 425 adult men and women born between 1980 and 2000. The contents of the survey were divided into four categories: general information, awareness of vegetables, awareness of vegan trends, and future needs for vegan trends. Results: Most respondents recognized the importance of eating vegetables and perceived vegetarianism and veganism as a lifestyle. Regarding the perception of the vegan trend, the highest response rate was 'The vegan trend is to be satisfied with my life regardless of other people', while the lowest response rate was 'The vegan trend is only a temporary fad'. The reasons for purchasing vegan products with high response rates were 'interest in the earth and environment', 'protection of animal rights', and 'thinking about health'. The type of vegan product wanted in the future was delicious food, and convenience level was in the order of 'completely cooked', 'half-cooked', and 'pre-processed'. Among the sustainable vegetarian types that millennials responded, 'semi-vegetarian', which can consume most animal products excluding red meat, showed the highest response rate. Conclusions: The positive perceptions about vegetables are expected to increase. Efforts should be made to develop convenient meals using vegetables and provide reasonable prices to expand vegetable intake.

  • Objective: Free-range systems have been increasingly available to the consumer due to increased demand for more sustainable meat-products. In the current study, the effect of free-range (FR) and cage system (CS) was explored on growth performance, meat quality and oxidation products in Italian White breed rabbits during the growing-fattening phase (5 to 13 weeks of age). Methods: Forty rabbits were randomly allotted to two treatment groups according to the rearing system, and each treatment group was replicated five times with four subjects in each replicate (20 rabbits per treatment-group). All rabbits fed the same diet as pelleted, and under FR system, no additional feeds were available to animals. Results: Rearing system had significant effect on rabbit growth performance, where CS group resulted in higher final body weight (p<0.045) and gain (p<0.029) and better feed efficiency (p<0.025) compared to FR rabbits. Most carcass traits were not affected by rearing system; however, a reduction of abdominal fat content (p<0.015) and meat lipids (p<0.034) was observed in FR rabbits. Rearing system had no effects on meat fatty acid profile, whereas meat from FR rabbits resulted less susceptible to lipid and protein oxidation compared to caged animals. Conclusion: In overall, FR system could be suggested as a substitute for conventional caged system because of FR system preserved rabbit meat from oxidation.
