Purpose: Although, the rate of skipping breakfast among adolescents has increased in recent years, there has been an increase in the consumption of home meal replacement (HMR). This study examines the recognition and preference of rice-based Korean style HMR for breakfast among adolescents in located at Jeollabuk-do. Methods: Total of 550 middle- and high-school students of Jeollabuk-do enrolled in this study signing a consent of participation. After conducting a preliminary survey, the questionnaire employed was modified according to the purpose of this study, and the self-recording method was appliedto fill out the questionnaire. Data were analyzed using IBM SPSS Statistics 25. The 𝛘²-test was performed for categorical variables, whereas continuous variables were analyzed by the independent t-test. Results: Results of this study determined that 272 students (54.6%) belonged tobreakfasteating group and 226 (45.4%) were in the breakfast-skipping group. The reasons specified by both groups for eating HMR were 'convenient to cook', 'delicious', and 'time-saving'. The a result of analyzing perception of the importance of HMR by classifying as whether to eat or not to eat breakfast, revealed that compared to the breakfast-skipping group, the breakfast-eating group considered 'hygiene and cleanliness' as important factors (p < 0.001). Considering the gender, school, and breakfast consumption, the most preferred Korean HMR were 'triangular gimbap', 'gimbap', and 'rice balls'. Conclusion: Results of this study indicate, when considering adolescents, there is a necessary for continuous researches to develop convenient breakfast substitutes that are easily consumed. Moreover, we believe that it is essential to impart proper cooking education and recipe distribution of the menu.

Objectives: This study investigated the different perceptions of customers toward traditional and non-traditional fast-food restaurants regarding restaurant healthfulness, corporate reputation, and the impact of corporate reputation on loyalty intentions through corporate social responsibility (CSR) motive. Methods: An online survey was conducted on U.S. residents who were aware of fast food restaurants' CSR activities. Participants selected one fast food restaurant participating in CSR activities, coded as either traditional (n = 117) or non-traditional (n = 48), and answered questions about the selected restaurant's healthfulness, reputation, CSR motives, and loyalty intentions. The participants' perceptions of healthfulness and corporate reputation of the two types of fast-food restaurants were compared. A mediation path of corporate reputation - CSR motive - loyalty intention was analyzed. Results: Non-traditional fast-food restaurants (5.02 ± 1.26) were perceived to be more healthful than traditional ones (3.93 ± 1.72). The participants perceived that compared to traditional fast-food restaurants, non-traditional ones had a better overall corporate reputation (P = 0.037), were more concerned about their customers (P = 0.029), better workplaces (P = 0.007), more environmentally and socially responsible (P < 0.001), and offered higher quality products and services (P = 0.042). Significant positive correlations were shown between restaurant healthfulness and corporate reputation (P < 0.001 for all reputation items). The suggested mediation path was supported with 95% CIs excluding zero, implying that when fast-food restaurants had a better reputation overall, were customer oriented, good employers, strong companies with a good product and service quality, social and environmental responsibility, the participants were more likely to perceive their CSR activities to be sincere and were hence loyal to that restaurant. Conclusions: Overall, participants were more favorable towards non-traditional fast-food restaurants which had a healthier image and better reputation than traditional ones. Therefore, fast food restaurants need to consider offering healthy food and enhance their image, which would maximize the return on their investment in CSR.

The purpose of this study was to examine the moderating effects of social support on material hardship of low-income elderly people that have been excluded from the National Basic Livelihood Security System. For this research, data of 255 persons aged 65 and over were collected using a survey conducted in 2014 by the National Human Rights Commission of Korea on the minimum living cost of low-income household. Data analysis was performed through descriptive analysis, correlation analysis, and multiple regression analysis with STATA13. According to the results, the average level of material hardship in low-income elderly people was 1.45 out of 6, with the most hardship shown in heating and health care. The results of multiple regression analysis showed that when low-income elderly people became excluded from the system, they suffered more than the recipients. They also showed that the social support system of low-income elderly people brought a negative impact on their material hardship when they were connected by the strong social support system. In other words, social support system reduced their material hardship caused by exclusion. Based on the results, this study suggests some practical and political means to reduce material hardship of low-income elderly people.

Distributions of 15 PAHs and 82 PCBs were investigated in sediment and fish samples collected from the Suyoung Estuary of Busan, one of the most urbanized and newly contaminated areas in Busan. The concentrations of $S_{15}PAH$ in sediments ranged from 17.9 to 777 ng/g-dry and were mainly originated from combustion processes. The concentrations of $S_{82}PCB$ in sediments ranged from 0.55 to 12.5 ng/g-dry and were significantly correlated with those of 12 dioxin-like PCBs and 6 non-dioxin like PCBs. Higher concentrations of PAHs and PCBs were found in the upper river and the inner Suyoung Bay than in marina and the outer Suyoung Bay. No sites exceeded the ecotoxicological values of PAHs and PCBs in marine sediments. Benzo[a]-pyrene was not detected in fish samples and the concentrations of $S_4PAH$ (0.15~0.45 ng/g-wet) were lower than the maximum level set by EU. The levels of PCBs in fish samples were at less than 1% of the Korean maximum level and 2% of the EU maximum level. The concentrations of dioxin-like PCBs were $0.01{\sim}0.32pg-TEQ_{WHO-2005}/g-wet$, and the highest concentration was found in eels, which were at less than 5% of the EU maximum level. Dietary intakes of PAHs and PCBs through fish consumption were estimated, and their lifetime cancer risk and non-cancer risk were much lower.

The Stockholm Convention, which was adopted in Sweden in 2001 to protect human health and the environment, includes regulations for Persistent Organic Pollutant Rotors such as toxic and bioaccumulatives. Currently, there are 28 types of materials. This prohibits and limits the production, use, and manufacture of products. Korea is a member of the Convention, and it is necessary to prepare management and treatment plans to address the POP trends. Thus, we experimentally investigate whether the environmentally stable incineration is achieved when the sample is thermally treated using the Lab-scale (1 kg/hr). The target samples is pesticides in liquid phase and solid phase. In this study, organic chlorinated pesticides and their thermal characteristics were analyzed. We calculated the theoretical air volume based on the element analysis results. Because the interior of the reactor is small, more than 10 times of the air ratio was injected. The retention time was set to at least 4 seconds using a margin. The incineration temperature was $850^{\circ}C$ and $1100^{\circ}C$. Thus, we experimentally investigated whether the environmentally stable incineration was achieved when the sample was thermally treated using the Lab-scale (1 kg/hr). We analyzed five types of exhaust gas; the 02 concentration was high, but the CO amount decreased. Complete combustion is difficult because of the small size of the furnace due to the nature of Lab-scale. The organic chlorine-containing pesticide had an average decomposition rate of 99.9935%. Considering the decomposition rates of organic chlorine-containing pesticide in this study, the incineration treatment at over 2 ton/hour, which is typical for a conventional incinerator, is possible. Considering the occurrence of dioxins and unintentional persistent organic pollutants, it can operate at more than $1,100^{\circ}C$.

With a long-lasting pandemic of COVID-19, we have faced unprecedented socioeconomic threats. The regulation of human exchange has exposed us not only to the threat of health and medical care problems, but also to the burden of the contraction of economic activity. The outbreak of COVID-19 did give us an opportunity to reexamine the social safety net which has been prepared for such crisis situations. The current study, in this vein, aims to investigate the impact of evaluations of social safety nets on the trust in government and on individual willingness to accept tax increases. To this end, this study has explored the data from a survey conducted on 1,000 adult men and women across the country (South Korea) in May, 2020, when COVID-19 has entered a pandemic phase. The analysis result then has shown that the evaluation of social safety net after the outbreak of COVID-19 had a positive impact on the trust in the government, which in turn led to the increase of the willingness to accept tax increases. Moreover, the positive impact of trust in government on the willingness to accept tax increases has been more amplified when the income level was increased. These results could contribute to laying the theoretical foundation for restructuring the policies and systems for the post COVID-19 era.

Particulate matter(PM) is one of the leading causes of lung cancer. Recognizing its considerable risk to human health, people change their behaviors when a concentration level of PM is high. The impact of particulate matter on urban activities may vary depending on the lasting days of PM and PM matter alerts. In addition, the level of averting behavior may vary depending on the types and physical characteristics of urban activities and the degree of vulnerability to PM among people. Although the way people respond to PM may vary depending on these various factors, previous research evidence on this is very insufficient. Therefore, this study multilaterally analyzed the impact of PM on the urban activities in Jongno-gu, one of the CBD areas of Seoul. For this, we linked SKT's mobile phone signal data to land use data to extract the daily number of active people by urban activity types and ages. According to multiple regression analysis, the averting behavior varies depending on the type of urban activity, the physical characteristics of the place of activity(inside and outdoor), the lasting days of PM, PM alerts and the age of people. The results of this study can be used as basic data to policy makers who establish policies for adapting to air pollution policies by providing various effects of PM on the urban activities.

This paper reviewed the necessity of a information and communication technology (ICT)-based smart livestock system as a development strategy for the animal life industry in the future. It also predicted the trends of livestock and animal food until 2050, 30 years later. Worldwide, livestock raising and consumption of animal food are rapidly changing in response to population growth, aging, reduction of agriculture population, urbanization, and income growth. Climate change can change the environment and livestock's productivity and reproductive efficiencies. Livestock production can lead to increased greenhouse gas emissions, land degradation, water pollution, animal welfare, and human health problems. To solve these issues, there is a need for a preemptive future response strategy to respond to climate change, improve productivity, animal welfare, and nutritional quality of animal foods, and prevent animal diseases using ICT-based smart livestock system fused with the 4th industrial revolution in various aspects of the animal life industry. The animal life industry of the future needs to integrate automation to improve sustainability and production efficiency. In the digital age, intelligent precision animal feeding with IoT (internet of things) and big data, ICT-based smart livestock system can collect, process, and analyze data from various sources in the animal life industry. It is composed of a digital system that can precisely remote control environmental parameters inside and outside the animal husbandry. The ICT-based smart livestock system can also be used for monitoring animal behavior and welfare, and feeding management of livestock using sensing technology for remote control through the Internet and mobile phones. It can be helpful in the collection, storage, retrieval, and dissemination of a wide range of information that farmers need. It can provide new information services to farmers.
