This study was conducted to supplement new-normal strategies on management plans of rural groundwater resources in the era of Post COVID-19. Global outbreak of COVID-19 has damaged across all areas including public policy, economics, industrial services, and others without exception, which has resulted in establishing new-normal strategies in order to restore balance and functions as for these areas. The new-normal ones were represented as enhancing preventative management on infectious diseases, expanding non face-to-face services, enhancing protective trades and food securities, and preparing growth policies on public services using the 4^th industrial revolution techniques. In this study, G-WASH_AD (Groundwater supply, sanitation, and hygiene with attraction and digitization) was suggested to be new-normal strategies on rural groundwater resources. The G-WASH_AD was consisted of three detailed action plans: a preventative plan on waterborne-diseases of groundwater (PP), a groundwater-tourism plan with rural heritage (GP), and an application plan of the 4^th industrial revolution techniques to groundwater facilities and its data (P4). The PP can contribute to protect human health from waterborne-diseases and minimize hazardous effects on crop cultivation. The GP accompanied with high-quality groundwater resources is able to strengthen rural tourism, to promote marketing activities on local agricultural products, and to increase household incomes of rural communities. The P4 can reinforce fast, comfortable, and scientific management on groundwater facilities and its data, creating a virtuous cycle between innovative management on groundwater and growth of technology related to it. Results of the G-WASH_AD strategies can encourage a green growth engine in field of rural groundwater management keeping up with Post COVID-19.

Genetically modified (GM) crops are not permitted to be cultivated in Korea, but can only be imported as food or feed purposes. The import of GM crops has sharply increased in recent years, thus raising concerns with regard to the unintentional escape of these crops during transport and manufacturing as well as the subsequent contamination of local, non-GM plants. Hence, monitoring of GM crops was studied in or outside of grain receiving ports as well as from feed-processing plants in Korea during July 2008. We observed spilled maize grains and established plants primarily in storage facilities that are exposed around the harbors and near transportation routes of the feed-processing areas. Based on the PCR analyses, a total of 17 GM maize plants and 11 seeds were found among the samples. In most cases, the established maize plants found in this study were at the vegetative stage and thus failed to reach the reproductive stage. This study concludes that, in order to prevent a genetic admixture in the local environment for GM crops or seeds, frequent monitoring work and proper action should be taken.

A series of experiments using atmospheric-pressure non-thermal plasma coupled with transition metal catalysts were performed to remove ethylene from agricultural storage facilities. The non-thermal plasma was created by dielectric barrier discharge, which was in direct contact with the catalyst pellets. The transition metals such as Ag and $V_2O_5$ were supported on ${\gamma}-Al_2O_3$. The effect of catalyst type, specific input energy (SIE) and oxygen content on the removal of ethylene was examined to understand the behavior of the hybrid plasma-catalytic reactor system. With the other parameters kept constant, the plasma-catalytic activity for the removal of ethylene was in order of $V_2O_5/{\gamma}-Al_2O_3$ > $Ag/{\gamma}-Al_2O_3$ > ${\gamma}-Al_2O_3$ from high to low. Interestingly, the rate of plasma-catalytic ozone generation was in order of $V_2O_5/{\gamma}-Al_2O_3$ > ${\gamma}-Al_2O_3$ > $Ag/{\gamma}-Al_2O_3$, implying that the catalyst activation mechanisms by plasma are different for different catalysts. The results obtained by varying the oxygen content indicated that nitrogen-derived reactive species dominated the removal of ethylene under oxygen-lean condition, while ozone and oxygen atoms were mainly involved in the removal under oxygen-rich condition. When the plasma was coupled with $V_2O_5/{\gamma}-Al_2O_3$, nearly complete removal of ethylene was achieved at oxygen contents higher than 5% by volume (inlet ethylene: 250 ppm; gas flow rate: $1.0Lmin^{-1}$; SIE: ${\sim}355JL^{-1}$).

Home health care is one of the important components of health care services. Today, the need and demand for the home health care is increasing. To assess the effects of home visit health services by public health nurses in health center on the stat of health, use of medical services and quality of life by elderly people living at home, a randomized controlled trial was implemented for 65 years or more old people randomly allocated to intervention(93) and control(118) group. Intervention group received 2 visits a month over 6 months. Control group received no home visits. The data was collected in a one-year follow-up survey conducted at Kyongju before and after the intervention which composed of health risk assessment, risk factor education and health related behavior counseling. The prevalence rate of chronic illness was more decreased in intervention group than control group after intervention. The intervention group visited medical facilities less frequently than control group. And the home visit health services encouraged the elderly to practice regular exercise. After the intervention, the score of ADL(activities of daily living), LSI(life satisfaction index) and SSI(social support index) in intervention group were more increased than control group. And the increase of scores was more prominent in 70 years or more old people, female, non-smoker and non-chronic illed elderly rather than others. In conclusion, the regular home visit health services provided by public health nurses were beneficial for the elderly in terms of health promotion and quality of life.

The purpose of this study is to present the implications of the rural living area setting and rural spatial structure analysis of the rural spatial strategy plan through case analysis. Following the decentralization of autonomy and the promotion of the transfer of state affairs to local areas, some of the general agricultural and fishing village development projects of the Ministry of Agriculture, Food and Rural Affairs were transferred to local areas. In addition, in 2020, the Ministry of Agriculture, Food and Rural Affairs introduced a rural agreement system for 113 cities and counties. However, since the understanding of the field is still low, this study attempted to present implications through a case analysis of the structure of rural space and the establishment of rural living areas in three local governments in Chungcheong. As a result of the study, in the stage of establishing the living zone, it is necessary to comprehensively review the contents reviewed in the analysis of the current status and conditions. However, the two local governments had insufficient interpretation of the axis by function and the establishment of the base area, or were using the upper plan as it was. Second, the source of the data used in the survey on the distribution status of living SOC facilities is unclear. Since the distribution status of living SOC facilities overlaps with accessibility analysis, OD data analysis, and resident survey results and is used as the basis for setting living areas, the data source should be clearly marked, and verification should be possible. Third, amenity (facility) resources were classified and analyzed according to the conditions and characteristics of local governments. The local government that applied the guidelines as they were was A local government, and the remaining local governments conducted surveys and analysis according to the current status. Forth, since the establishment of the rural living area is the minimum unit supported by government policies through future rural agreements, it is necessary to distinguish them based on quantitative standards in the process of establishing them. Only one case area presented clear grounds and standards, and the rest of the case areas presented standards but are based on non-quantitative standards. In order for rural agreements to be sustainable in the future and benefit local residents, it is necessary to use or establish a government-level institution that can collect and produce objective data. In addition, it is necessary to find ways to specify and standardize the standards for setting the living area and specify them in the guidelines.

The purpose of this study is to verify the result of the previous studies and to clarify the types and activation factors of maintenance activities of the naturally favorable water space through the participation of residents in rural areas, through a further survey of the area proposed as a program in the existing study review and previous study related to the participation of residents. The survey was conducted through the survey of 1,242 households and 1,335 persons intended for Japanese rural areas. The study result is summarized as follows. The types of the maintenance activities in the areas intended for the survey have been classified into 'rural type' and 'combination type' through the analysis results by the references like the comparison analysis, job percentage and main utilization purpose of facilities for each type of maintenance and operation activities. In case of the 'rural type' area, residents were doing maintenance activities centered on the group activities rather than personal maintenance activities. Also, the activities of maintenance & operation group members were more active than non-members, and the water-friendly utilization to the facilities was not directly affecting the maintenance activities of residents. In case of the 'combinational type' area, there was no common characteristic according to each area, and the participation percentage in the maintenance activities was low compared with the 'rural type' area. According to the analysis result based on the participation degree of personal maintenance activities, the repair of facilities as a naturally favorable water space, implementation of projects reflecting the opinions of residents, educational programs conducted in order to motivate the participation of residents, etc. have been analyzed as the factors affecting the activation of maintenance activities of residents. Through the above results, for continuous maintenance activities to be made with residents as a main body in the future, it is necessary to support maintenance groups on an administrative level and procure experts for the production and operation of programs that can increase the participation percentage of residents.
