  • In this paper, we propose a study on DB-based automatic crop cultivation that obtains crop cultivation data using IOT and automatically controls the cultivation environment using it. A system for DB-based automatic crop cultivation that automatically controls the cultivation environment is composed of a management server and a local controller. The management server was implemented using the MySQL DB in the Linux server system, and the local controller was designed and manufactured using the WiFi module and ARM Coretax-3 series MCU and confirmed its operation in the laboratory. The purpose of this study is to provide the optimal cultivation data and to grasp the cultivation status in real time when the knowledge of professional cultivation is needed like the farmers of ear farm villages. Research should continue to enable the cultivation of crops to reflect the requirements of each user.

  • Rice blast is the most destructive disease threatening stable rice production in rice-growing areas. Cultivation of disease-resistant rice cultivars is the most effective way to control rice blast disease. However, the rice blast resistance is easy to breakdown within years by blast fungus that continually changes to adapt to new cultivars. Therefore, it is important to continuously monitor the incidence of rice blast disease and race differentiation of rice blast fungus in fields. In 2020, a severe rice blast disease occurred nationwide in Korea. We evaluated the incidence of rice blast disease in Yeoju and compared the weather conditions at the periods of rice blast disease in 2019 and 2020. We investigated the races and avirulence genes of rice blast isolates in Yeoju to identify race diversity and genetic characteristics of the isolates. This study will provide empirical support for rice blast control and the breeding of blast-resistant rice cultivars.

  • The AMMI (additive main effects and multiplicative interaction) and GGE (genotype main effect and genotype by environment interaction) biplot which were accounted for a substantial part of total sum of square in the analysis of variance suggested to be more appropriate models for explaining G $\times$ E interaction. The grain yield of total ten sesame genotypes was significantly affected by environment which explained 61% of total variation, whereas genotype and genotype x environment interaction (G $\times$ E) were explained 16%, 24% respectively. From the results of experiment, three genotypes Miryang49, Koppoom and Ansan were unstable, whereas other three genotypes Kyeongbuk18, Miryang50 and Kanghuk which were shorter projections to AEA ordinate were relatively stable over the environments. Yangbak which was closeness to the mean yield and short projection of the genotype marker lines was regarded as genotype indicating good performance with stability. Ansan, Miryang48 and Yangbaek showed the best performance in the environments of Naju, Suwon, Iksan and Andong. Similarly, genotype Miyrang47 exhibited the best performance in the environments of Chuncheon and Miryang. Andong is the closest to the ideal environment, and therefore, is the most desirable among eight environments.

A Study on the Aims of Cultivation Techniques of Joseon and the Imwon-gyeongje-ji, With a Focus on the Interconnection of Body-Environment-Society (『임원경제지(林園經濟志)』와 조선(朝鮮) 양생(養生)의 지향(志向)에 대한 연구(硏究) - 몸-자연-사회의 연계를 중심으로 -)

  • Objectives : This paper intends to examine the essence of Joseon's cultivation techniques as written in the vast encyclopedia Imwon-gyeongje-ji. Methods : Items related to cultivation techniques in the Imwon-gyeongje-ji were brought together and analyzed through various cases that match the theme and structure of this paper, focusing on the relationship of Body-Environment-Society Results & Conclusions : Based on the contents of the Imwon-gyeongje-ji, it could be said that Seo Yu-gu consistently attempted to secure and improve health, well-being, and welfare in all levels of an individual's body, environment, and society while stating to have integrated Buddhist and Daoist methods based on Confucius cultivation. This thought is linked to the ideals of Zhongyong, one of the main scriptures of Confucianism, which could be summarized by the concept of the Heaven-Earth Cultivation. In specific, contents within the 16 treaties of the Imwon-gyeongje-ji such as the Boyang-ji, Inje-ji, Jeongjo-ji, Yewon-ji, Yiwun-ji, Yuye-ji, Yegyu-ji, etc., that could be categorized as personal, environmental and societal cultivation has great implications for people today in that it could lead us to an integrated path of cultivation through the inter-connection of body, environment, and society.
