Objectives: The main objective of this study is to investigate domestic usage amount of insecticide for vegetable cultivation to provide fundamental data for establishing job-exposure matrix(JEM) related to farmers treating agricultural insecticide. Materials and Methods: The survey on domestic usage amount of insecticide for vegetable cultivation was conducted by two research methods. The first method is to utilize agricultural pesticides published annually from Korea Crop Protection Association(KCPA). The second method is to apply cultivation area of vegetable announced officially from Statistics Korea(SK). An estimation of domestic usage amount of insecticide for vegetable cultivation through the second method was done by multiplying total cultivation area of vegetable($m^2$) with optimal spray amount of insecticide for vegetable cultivation per unit cultivation area of vegetable ($kg/m^2$). Results: As a result of analysis of public data related to insecticide for vegetable cultivation, it was found that its domestic usage amount has decreased gradually from the first sale year(1969) to current year(2012). There is, however, a considerable difference of annual usage trend of insecticide for vegetable cultivation between shipments and estimation. The annual usage trends of insecticide for vegetable cultivation based on regional classification were different from those based on total aspect. Conclusions: The region which used insecticide for vegetable cultivation the most in Korea was Jeolla-do, followed by Gyeonsang-do, Chungcheong-do, Seoul/Gyeonggi-do, Gangwon-do and Jeju-do. Substantially, mean ratio of usage amounts of insecticide based on shipments and those based on estimation by cultivation area was $281{\pm}115%$, which indicates that usage amounts of insecticide estimated by cultivation area are three times lower than those based on shipments.

Most of the current cultivation log is recorded by growers manually or whose environment information is input based on the grower's own judgement. It is not easy for growers to record the image of disease and insect pests in the cultivation log. In this regards, u-Farm cultivation log management system based on Web 2.0 and smart phone is introduced in this paper, that is used for the effective cultivation management and grower's convenience. In the system, the value of environment information is transmitted to servers via sensors. It designs and implements Web 2.0 Flex so as to make the cultivation log more reliable and provide users with active, convenient GUI in case the log is recorded by desktop. In this process, detailed modules are designed by object-oriented UML considering the reusability and maintenance of the system. Moreover, the system introduced in this paper is proved to be more excellent by the qualitative assessment compared with the other researches.

This poper proposes a manpower cultivation index(MCI) which can be used for evaluating how much a research project contributes for manpower cultivation. The four factors which are considered to influence the manpower cultivation are the number of participated graduate students(research assistants) , the number of graduate students who obtain master or Ph. D. degrees among the participated graduate students in the research project, the number of research papers published by participated graduate students, and the number of graduate students who get jobs. By the proposed MCI, three major research projects of KOSEF are analysed in terms of manpower cultivation. These are SRC/ERC(Science research center/Engineering research center) and RRC(Regional research center) and OBR(Objective based research) . The computed MCls show that the three major research projects enjoy satisfactory manpower cultivation to some extent.

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.

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.

Objectives : Various cultivation methods can be found suggested in Donguibogam(東醫寶鑑) Naegyeongpyeon(內景篇) ranging from Juchenhwahu(周天火候), massage(按摩), physical and breathing exercise(導引), fetal breathing(胎息), clicking teeth(叩齒), saliva swallowing (嚥液), sounding the celestial drum(鳴天鼓), Six words(六字訣), Seven step(七星步), God pillow method(神枕法), and Taoism. Methods : The cultivation methods in Donguibogam are mainly found in the first volume of Naegyeongpyeon, and some can be discovered in Oehyeongpyeon(外形篇) and Japbyeongpyeon(雜病篇). This paper aims to study the system and special features of the cultivation methods that unfold within the first volume of Naegyeongpyeon. Results : Donguibogam's cultivation methods are Jing-Qi-Shen cultivation method(精氣神養生法), and Naegyeongpyeon's Sinhyeong(身形) can be described as a collection of general remarks, and Jing(精), Qi(氣), and Shen(神) is dealt individually. The condition for Jing culvation is not to spill sperm, Qi cultivation is to control the breathing, and Shen culviation is having a calm mind. Conclusions : The Jing-Qi-Shen cultivation method of Donguibogam revolves around Taoism integrated with Buddhism. It places importance in the cultivation of the Inner Center(內丹), and emphasizes Shen in particular among Jing, Qi, and Shen.

In order to develop a smart cultivation facility based on ICT (Information Communication Technology), a cultivation house was selected. Sensor devices were installed to monitor any changes in the cultivation environment. A control panel was constructed to monitor and control the data on environmental changes collected by the sensors. To efficiently manage the proceedings of the cultivation environment, the cultivation process was divided into 4 stages. We designed an environmental control module using these processes. PC and mobile phone software were designed for remote monitoring and control to develop a smart cultivation system that can conveniently manage the cultivation environment and produce mushrooms in a more stable manner.

In order to construct an artificial cultivation of Nostoc flagelliforme on solid medium, we attempted to assess the viability of approaches, which utilized either BG-11 agar or sand medium using both sterile and non-sterile algal segments. In the trial in which the BG -11 agar medium was inoculated with the non-sterile algal segments, the algae exhibited the rapid growth in the initial 4 days of cultivation. However, after 4 days of cultivation, the growth rate of the algae slowed, and the algal growth was completely stopped by 7 days of cultivation. When the BG -11 medium was inoculated with the sterile algal segments, the algae exhibited the rapid growth for a longer period of 8 days, reaching a length of 24.9 mm. The growth rate during this period was measured to be $24.5\%$. After the 8 days of cultivation, the algal growth rate began to slow and had almost stopped by the 13 days of cultivation. On the other hand, when the sterile algal segments were inoculated onto a sand plate, the algal segments decomposed, reaching total decomposition after 11 days of cultivation. By way of contrast, the desiccation treatment samples continued to grow for 14 days of cultivation. After 14 days of cultivation, the algae achieved a length of 26.1 mm, with a growth rate of $30.6\%$. Our results indicate that periodic desiccation may constitute an effective strategy for the prevention of algal decomposition.
