Objectives: This study was performed to estimate domestic usage amount of insecticide for fruit cultivation to suggest job-exposure matrix(JEM) regarding farmers treating agricultural insecticide. Materials and Methods: The domestic usage amount of insecticide for fruit cultivation was investigated according to two research methods. The former method is to use agricultural pesticides published annually from Korea Crop Protection Association(KCPA) and the latter method is to apply cultivation area of fruit provided officially from Statistics Korea(SK). Results: It was found that its domestic usage amount has decreased gradually from the first sale to presence(2012). However, there is a significant difference of annual usage trend of insecticide for fruit cultivation between shipments and estimation. The annual usage trends of insecticide for fruit cultivation based on regional classification were different from those based on total aspect. Conclusions: The region which used insecticide for fruit cultivation the most in Korea was as follows: Gyeonsang-do, followed by Jeolla-do, Chungcheong-do, Jeju-do, Seoul/Gyeonggi-do and Gangwon-do. An averaged ratio of usage amounts of insecticide based on shipments and those based on estimation by cultivation area was $980{\pm}186%$, which means that usage amounts of insecticide estimated by shipments are ten times higher than those based on cultivation area.

In this study, the characteristics of soybeans with different cultivation methods depending on their origins and the properties of tofu made from these soybeans were studied. The isoflavone content was higher in the general Korean soybeans compared to the organic American soybeans. There were no significant differences among the Chinese soybean samples, so the cultivar method was considered to have a greater effect on the isoflavone contents rather than the cultivation method. The protein contents were higher in the tofu made from the general Chinese soybeans and the organic Korean soybeans. Furthermore, the tofu made from the organic Chinese soybeans contained the least amount of proteins. Isoflavone contents were not significantly different among the samples. Texture profile analyses consisting of hardness, cohesiveness, adhesiveness, springiness, and gumminess were all shown to be higher in the organic tofu than in general tofu, with the exception of adhesiveness. In sensory evaluation, color and texture were significantly different according to the samples, and the differences were found to be affected more by the origin of soybeans rather than the cultivation methods. According to this study, the physicochemical properties of the soybeans and tofu seemed to be influenced by the cultivation region rather than the methods.

The edible paddy straw mushroom Volvariella volvacea (Bull. ex F.) Singer has high nutritional and medicinal values. They are grown on a wide variety of agricultural by-products using different several methods. The result of this present study showed that type of bed and cultivation condition (outdoor/indoor) had effects on the yield of paddy straw mushrooms grown on the spent oyster mushroom sawdust. The treatment of circular compact bed under indoor cultivation condition (CYIC) had the best yield and biological efficiency (B.E.) with 2,119.2 g/bed and 14.5%, respectively, followed by the treatment of conventional bed under outdoor cultivation condition (COOC) with the yield and B.E. of 1,935.5 g/bed and 13.2%, respectively, but the lowest yield and B.E. were observed in the treatment of conventional bed under indoor cultivation condition (COIC) with 1,226.1 g/bed and 8.4%, respectively. Paddy straw mushrooms cultivated on spent oyster mushroom sawdust should be proper in both outdoor and indoor conditions by conventional and circular compact methods as well. However, in indoor conditions, paddy straw mushrooms should be grown in a circular compact bed to ensure the temperature of the bed is suitable for the mushroom growth.

Labor required for managing and harvesting the oyster mushroom bed was evaluated. Although vinyl mulching cultivation method needs more hours for spawning, it saves more than 50% of labor for harvesting and managing of the mushroom bed. Harvesting hour of 1st-3rd flush in vinyl mulching method was 48~50% for Plerutus ostreatus and 36~41% for P. sajor-caju. Labor for bed management after harvesting in vinyl mulching method was also 38~50% for P. ostreatus compared to conventional method, and 20~35% for P. sajor-caju. Vinyl mulching is believed to be a very efficient method for saving labor in oyster mushroom cultivation.

To establish a cultivation method of Petalonia fascia, seeds and seedlings cultures and growth tests were performed at the Daeri aquafarm in Haeui, Shinan, Jeollanamdo, Korea. Gametes were easily released from the mature plurilocular sporangia. They developed to crustose discoidal stolons and grew to filamentous and discoidal stolons. The indoor seeding was performed by using the 100-150 ${\mu}m$long fragments of stolons on Porphyra nets and the erect thalli developed from the cuttings when the seawater temperatures were 10-15$^{\circ}C$. In the experimental cultivation in the sea, 1-2mm long plantlets were found after 15 days of cultivation; after two months thalli grew to their maximal size of 215-355 mm long blades; after three months the length of thalli began to decrease due to distal disintegration and the plant color changed to yellow and epiphytic diatoms were attached on the thalli, which deteriorated the quality of products. The cultivation of P. fascia by the regeneration of filamentous-discoidal complexes was carried out successfully for the first time in Korea.

파종시기와 포장조건을 달리한 콩의 논 재배 시 R2와 R5 시기의 생육반응과 R5 시기의 수량성을 분석한 결과는 다음과 같다. 공시 품종들의 경장에 있어서 R2와 R5 시기 모두 단작 시험구가 맥후작 시험구보다 긴 경향을 보였다. 파종 시기와 재배법 모두를 고려해 보면 단작의 경우 평휴 재배가 그리고 맥후작의 경우 고휴재배에서 다소 긴 경향을 보였다. 근류의 형성은 평휴보다 고휴재배에서 많았고, 파종기 및 재배 방법에 상관없이 황금콩이 가장 높았다. 단작 보다 맥후작 시험구에서 공시 5품종 모두 콩 생육기 진전에 따른 엽면적 증가 뚜렷하였다. 지상부와 지하부의 건물 생산량에 있어서 맥후작 보다 단작 시험구에서 높은 경향을 보이는데, 이는 생육기간의 차이 때문인 것으로 생각된다. 재배 방법 별로는 지상부 건물중이 평휴에서 높았던 반면 지하부 건물중은 고휴재배에서 보다 양호하였다. 이러한 지상부 및 지하부의 생육은 T/R율에 영향을 주는데, 재배 방법별로는 평휴조건이 T/R율이 높았으며, 파종시기별로는 단작의 T/R율이 맥후작보다 높았다. 태광콩, 대원콩, 황금콩은 R2 시기에는 단작의 T/R율이 높았던 반면, R5 시기에는 맥후작의 T/R율이 높았는데, 이는 이들 품종이 생육기 진전됨에 따라 지하부 생육이 지상부 생육에 비해 미약하기 때문으로 생각된다. 등숙기인 R8 시기에서 협수는 조생종인 화엄풋콩이 가장 적었고, 소립종인 은하콩이 가장 많았고, 통계적 유의성은 없으나 평휴보다는 고휴에서 그리고 단작구보다 맥후작 파종구에서 협수가 많은 경향이었다. 조생종인 화엄풋콩이 맥후작에서 등숙이 낮았고, 황금콩과 은하콩은 단작구보다 맥후작에서 등숙율이 높았다. 수량성은 품종간 차이가 있는데 대원콩과 태광콩에서는 6월 19일 파종이 5월 25일 파종에 비해 수량이 높은 경향을 보였다.

This study investigates the meaning, the method of "Cultivation of the fundamental" as aim of child education in context of the Xing-Li-Xue(性理學) educational theory. Chu-hsi understood the meaning of "Cultivation of the fundamental" as Ching(敬, the cultivation of good nature in human mind). The method of "Cultivation of the fundamental" consists of quiet sitting(정좌), attention(주의집중), moral environment(도덕적 환경) and practicing propriety(예의 실습). Through quiet sitting and attention, learners may reach a condition of mind which is free of their selfish desires and in which they can find out their original nature. The education in Confucianism accepts the environment as a significant element in forming human personality. Making moral environment has leaners to take good value with ease. Characteristic of study in Xing-Li-Xue is to emphasize to observe concrete clauses of propriety. The reason why Xing-Li-Xue emphasizes propriety is that Mind Study may be maintained through Body Study. In conclusion, the "Cultivation of the fundamental" in the Xing-Li-Xue is to form the power to regulate selfish desires and thus behave more moderately. Along these points, not only quiet sitting which relexes the body and soul, but also song and dance are not considered as contrary to Xing-Li-Xue educational theory. The various ways of "Cultivation of the fundamental" of Xing-Li-Xue educational theory make people recognize, understand and experience good innate nature of human beings. And we can reach the conclusion that education of Xing-Li-Xue uses so many methods that learner can accept moral value as naturally as possible.
