Recently, with the improvement of national income, the increase of int e rest in the consumers, health, and the enhancement of recognition of environment the demands of environmental-friendly agricultural products(EFAPs) are on the rise rapidly. The demand in the market for EFAPs increases rapidly, and the sales amount increases by 30~40% every year. But, it is in situation that the EFAPs arc not distributed well between the producers and consumers now. That is, the producers of EFAPs can not End th e ir markets. And, the consumers do not trust the EFAPs. Also, it is in situation that it is difficult to promote the demand because of relatively higher prices than the general agricultural products. To solve these problems, it may be summed up as follows. First, it needs to reduce the distribution cost by the construction of stable supply basis. Second, it needs to improve the distribution system of EFAPs. Third, it needs to enhance the differentiation and improve the consumers, reliability. Fourth, it needs to make in brand and extend the various publicities. Fifth, it needs to construct the supporting system and enhance the cooperation with the related institutions. Sixth, it needs to End new demand and introduce the procurement system by the government.

The study is a comparative analysis of the differences in economic activities of two rural villages near the city. It is the general notion that rural villages near large cities lose the characteristics of traditional rural villages and change the areas with urban characteristics due to the influence of urbanization. The survey also showed that Munho 4-ri and Jeongbae 1-ri in Gyeonggi-do have urban characteristics, such as population growth, agricultural activity reduction and non-agricultural activity increase, and community activity reduction. However, they also found that there were important differences in the future development patterns of the two villages. In other words, the reasons and purposes of migration of people moving to the two villages, the differences in the system of economic activity in the villages, and the differences in community cooperation are emerging. Therefore, the study shows that policies to develop rural villages near cities need to be implemented differently based on the characteristics of those villages.

This study aims to analyze the regional variations in which appear during the formation process of educational community in rural villages from the perspective of regional innovation theory. The study results revealed that the activities to form an educational community of the Songak village significantly influenced the variations across the social, economic and environmental aspects beyond an innovation of public education within the region based on interrelation between schools and villages. In other words, the activities including interactions and group learnings have been actively promoted among the various relevant stakeholders, thereby resulting in a variety of positive variations such as expanded regional welfare base, activated voluntary residents community gatherings based on the unity and cooperation, broadened socioeconomic opportunities, satisfaction on educational and cultural desires, and construction of healthy ecological environment in the region. Therefore, it is thought that regional development policy suitable for each region needs to be established by embracing the fact that activities to form a village educational community entail significant implication and value as the comprehensive regional innovation activities across the entire domains in each region.

To carry out the Integrated Fruit Production(IFP), researches on cover crops as well the Integrated Pest Management(IPM) and the Integrated Nutrition Management(INM) should be very important. These concepts are neither clear nor connective till now. The researches on cover crops in Europe and USA are being kept within the category of IFP. Main researches on fruit trees for sustainable agriculture in Italy are new variety creation, development of growing techniques, pest and disease control, and cover crops management, etc. It is necessary of fruit industry in Korea to maintain good quality and taco-friendly fruit production. For this goal, we need international cooperation with highly developed countries in Europe. In first step, we should enlarge research areas and analyze results obtained to get farmers understood the concept of cover crop growing, Furthermore, we make researches more profoundly on cover crops growing considering tree age, mixing rates among cover crops, seeding and cutting time for cover crops, and so on. Researchers, specialists of agricultural extensions, and farmers should concentrate their opinions and conduct IFP together. The IFP should go on systematically and reach finally to get certificates internationally by the International Organization for Biological and integrated Control of Noxious Animals and Plants(IOBC) to enhance selling and exporting fruits.

A copper-based metal organic framework (MOF) named Cu-BTC, also known as HKUST-1, was successfully synthesized by using a solvothermal method. The properties of the Cu-BTC sample were characterized with Powder X-ray diffraction (XRD) for phase structure, Thermogravimetric analysis (TGA) for thermal stability, Scanning electron microscopy (SEM) for crystal structure, and Nitrogen adsorption-desorption for pore textural structure. The analysis results displayed that the Cu-BTC sample exhibited a good crystal structure with uniform size of octahedral particles. The BET data revealed a high surface area of $1457 \;m^2g^{-1}$ and a pore volume of $0.60\; cm^3g^{-1}$. The Cu-BTCs ample was also studied for $CO_2$ adsorption and exhibited a maximum $CO_2$ adsorption capacity of 170 mg/g of the sorbent (3.8 mol/kg) at $25^{\circ}C$.

This research estimates the necessity of a better governance plan on the purpose of fulfillment energy recovery by building resource recycling system for biomass resources and waste resources that derive from agricultural and mountain village areas. The utilization of new renewable energy technology which uses waste and biomass sources diverse as variety of resources, collecting method, operator etc. and is structurally complicated the formation of policy is also very difficult. There is failure because of the problems which occurs from the policy led by government. Biomass Town Development Project should be made through the central government and the local government integrated support system and should be formed a consultative group in order to process the project mutually with these two department including the experts from the related areas. This consultative group, while government organizations carry out the hub function of strategic knowledge management, should carry out the control tower function to be able to be net working transfer the information with the cooperation of private and government so vitalize the communication area among the related actors. And to be able to increase the participation rate of the local people the consistent and various educations should be given so a smooth business promotion progress will be desired through the change of perception and coactive participation of people.

This study aimed to identify a difference in project implementation between villages that had executed rural village community activation support work successfully and those that had quit in the middle from the new endogenous development theory perspective. As a result, it was found that the main factors used for promoting to increase endogeneous development capabilities existed more in villages that executed project implementation support work successfully than in villages that had quit in the middle. Successful villages have a difference from the villages that had quit in the middle in that they have established a participatory decision making and cooperation system for stable operation even before their support work began, they have more assets for promoting community activity, residents' interaction and communal activity are becoming more active, and reciprocity-based mutual aid culture exists in many forms. In conclusion, seeing from the new endogenous development theory perspective, villages are developed under the interaction between internal and external factors, but the outcome of project implementation depends on whether village community holds its endogenous development capability to operate and develop such whole process of development. Therefore, village community activation policies need to be reinforced in the direction toward promoting to create the main factors for enhancing endogenous development capabilities.

This study analyzed farmers' and experts' perceptions of the Agricultural Income Survey (AIS) conducted by the Rural Development Administration and estimated its socioeconomic value. The research surveyed 104 farmers in Gyeongsangbuk-do and Jeollanam-do. To estimate the AIS's socioeconomic value, this study examined public information projects in the field of agriculture and public information, proposing an estimation methodology based on prior research. The socioeconomic value of the AIS was calculated in three stages (information generation, collection and analysis, and utilization) using the replacement cost and contingent valuation methods. In 2020, the estimated socioeconomic value of the AIS ranged from a minimum of KRW 631.2 billion to a maximum of KRW 799.1 billion per year. To improve the socioeconomic value of the AIS, it is important to booster awareness, expand sample sizes for more reliable data, increase manpower and budget, refine survey questions, and enhance analyzing capabilities. And it's crucial to foster cooperation with surveyed farms, promote collaboration among investigative agencies, improve investigator skills, and strengthen management capabilities to facilitate information dissemination.

Recent advances in digital technology and diversified internet services have resulted in a rapid growth of research on monitering systems using embedded web servers in USN systems. In designing USN systems equipped with wireless sensor modules requiring extra power for heating sensors for their appropriate operations, excessive power consumption introduces inefficiency to the entire system. In this paper, using embedded systems in web environment, we develop a remote-monitoring system with VOC (Volatile Organic Compounds) sensor signal, and propose a real time method of processing sensor-data streams by way of the serial bus from the sensor module in the USN system. The proposed system has an advantage of monitering the harmful gases on real-time basis and can be used semi-permanently by providing the sensor module with power through the serial bus. The harmful gas to be detected by the VOC sensor module is Toluene and the sensor module is composed of TGS-2602 VOC(Volatile Organic Compounds) sensors of FIGARO. The detected signal is transferred to the embedded web server using the RS-485 serial communication device. The proposed remote VOC monitering system is designed to coordinate in such a way that the VOC sensor module and embedded web server (EMPOS-II) work together effectively for real time monitering of harmful gases on the web at any places where the internet is connected.
