New series of sulfonylureas containing substituted thiophene with 2-chloromethyl-l,3-dioxolane group were prepared, and their herbicidal effects were tested(in vivo) in the upland conditions and in the paddy submerged conditions. The sulfonylureas in which 4,6-dimethoxy- or 4-methyl-6-methoxy group in pyrimidine or triazine ring showed good herbicidal effects at a rate of 0.1 ㎏/㏊. However, they showed weaker herbicidal effects than that of sulfonylureas containing substituted thiophene with 2-fluoromethyl-l,3-dioxolane group in general.

A series of bicyclic 4,5,6,7-tetrahydroindazole derivatives 6 have been synthesized, and their herbicidal activities were studied in flooded paddy condition. The compounds 6 showed herbicidal effects to bamyardgrass and Monochoria and good tolerance against rice at a rate of 0.063 ㎏/㏊~0.25 ㎏/㏊.
새로운 2-(5-Propargyloxyphenyl)-4,5,6,7-tetrahydro-2H-indazole의 합성과 제초활성

Of the cyclic imide type compounds, S-275 was known to exhibit a potent herbicidal effects. We have designed and synthesized the compounds having diverse substituents in place of the chlorine group of bicyclic 4,5,6,7-tetrahydroindazole part of S-275. Their herbicidal activities were studied under flooded paddy conditions. The results showed that the most compounds gave relatively weak herbicidal activities, whereas the compound substituted with methylthio group showed potent herbicidal effects against paddy weeds at a rate of 0.015 ㎏/㏊ and improved tolerance on rice compared to S-275.
5-Benzyloxymethyl-3-(thiophen-5-yl)-1,2-isoxazoline 유도체의 합성과 제초활성
전동주(Dong Ju Jeon),송종환(Jong Hwan Song),김형래(Hyoung Rae Kim),김은주(Eun Ju Kim),황인택(In Taek Hwang) 한국농약과학회 2007 농약과학회지 Vol.11 No.2
Nobel series of 5-benzyloxymethyl-3-(thiophen-5-yl)-1,2-isoxazoline derivatives were designed and synthesized. The herbicidal activities of these compounds to main dominant weeds to these compounds were evaluated in pot tests that simulated rice paddy conditions. Most of the compounds showed high herbicidal activity to main dominant weeds occurring in rice field without the serious rice injury.
새로운 9-(5-isoxazolemethoxyphenyl) imino-8-thia-1,6-diazabicyclo [4.3.0]nonan-7-one 유도체의 합성과 제초활성

New series of 9-(5-Isoxazolemethoxyphenyl)imino-8-thia-1,6-diazabicyclo[4.3.0]nonan-7-one which are the cyclic imide type compounds were designed and synthesized. The herbicidal activities of main dominant weeds to these compounds were evaluated under rice field condition. There is the possibility for a new herbicide since the most of compounds were excellent to main dominant weeds occurring in rice field without the serious rice injury.
신뢰성물리학분석 기법을 활용한 함정탑재 전자 구성품의 신뢰성 설계 개선 방안

Efforts on reliable design are required from the design stage for efficient operation, maintenance and management in terms of the entire life cycle of the weapon system. In this paper, the priorities for improvement were selected by adding the CEI index considering quantity and cost analysis to the general D-FMEA analysis method targeting the circuit card assembly mounted on the warship. In addition, the design improvement was performed using Sherlock, an RPA tool, and the methodology for cost reduction during the total life cycle of the weapon system was presented by comparing the improvement results.
