Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with fiorisil, and finally analyzed simultaneously the organophosphorus pesticides using GC/NPD, Ultra-2 and Ultra-1 fused silica capillary columns were used to separate and identify the products. Recovery of most analytes from soybean sample, taken from pesticide residues well, was greater than(80%) for all except(6) analytes. This method can simultaneously determine multiple pesticides with a high degree of accuracy and precision.

This paper designed a interrupt controller to interface peripheral devices to DSP using VHDL. It is proposed the design references and the model of interrupt controller to be designed in this paper. And the illustrations are presented about each function blocks of the model by symbolic circuits and flowcharts. The simulation results is also provided to illustrate the operation of the designed interrupt controller. This is tested at EP1K100QC208-3, ALTERA's FPGA, interfacing to TMS320VC33, TI's DSP.

We have synthesized protoberberine derivatives from tetra- hydroberberinium perchlorate. On quaternization of a several protoberberine derivativese with methyl iodide, the formation of the cis methiodides the corresponding trans methiodides increased according to the order of the bulkiness of the 14-substituent as H>CH₃>CN. The N-methyl signal of the cis 14-substituted quinolisidine methiodides was conformed to appear at higher field than those of the corresponding trans methiodides except for the 14-cyano methiodides in their NMR specta.

This study was conducted to suggest the mechanization strategy for rice direct seeding cultivation through reviewing the current rice cultivation status and its problem. The rice direct seeding cultivation can contribute to reduce production cost as well as to enhance the mechanization technology and related machine development. The objects and directions for rice direct seeding cultivation strategy, reviewed in this study, could be summarized as follows : 1. The breeding status for direct seeding cultivation is less uniform than transplanting cultivation, especially in large scale farming area. So, precision farming techniques for the operations such as seeding, fertilizing, water control etc., and proper farm machinery utilization system suitable for large scale farming area should be identified and introduced. 2. In order to get the effect of direct seeding cultivation such as reduction in production cost and save labor requirement, the following seeding machines should be developed and used in direct seeding cultivation, i.e. no or partial plowing machine, direct seeder for dry field, and direct seeder for wet field, which can be used for simultaneous operation of seeding, fertilizing, and weeding. 3. Governmental & private organizations concerned with agriculture and farm machinery should agree positively with the direct seeding cultivation policy. 4. It is urgent that development of precision farming technology and its mechanization suitable for korean field conditions with the assistance of information technology such as GPS and GIS.

As a fundamental study in the development of a distillation process for ferromanganese alloy melts, the evaporation behavior of an electrolytic manganese melt under reduced pressure was investigated. The melt temperature, vacuum degree, surface area of the melt, and reaction time were considered as experimental variables. The amount of vaporized manganese increases linearly as the reaction time increases, and the evaporation of manganese was promoted by increasing the temperature and surface area of the melt. In the pressure range below the equilibrium vapor pressure of manganese, the amount of vaporized manganese per unit surface area of the melt increased sharply with a decrease of the pressure in the reaction chamber. An empirical equation for the evaporation rate of manganese was derived by regression analysis. The evaporation coefficient of manganese was determined to be approximately 3.84×10(-3) (g·K1/2)/(Pa·cm2·min) under the investigated conditions.

대상포진에 의한 상완 신경총염은 매우 드문 질환이며, 일측 상지의 악화되는 통증, 근력 약화 및 늦은 회복을 특징으로 한다. 본 증례는 대상포진 바이러스에 의한 상완신경총염을 진단받은 54세 여자 환자가 이른 치료 시기에 통증 자극과 혈관수축 및 신경반흔 형성을 억제할 수 있는 성상신경절 차단술을 통해 빠른 회복을 보인 경우이다. Varicella zoster virus (VZV)-induced brachioplexitis is a rare disease, characterized by exacerbating ipsilateral upper extremity pain, muscular weakness, and delay in recovery. We report a 54-year-old female patient who made an early recovery from VZV-induced brachioplexitis via the treatment with stellate ganglion blocks, which may have prevented pain sensation, vasoconstriction, and nerve scarring during the early treatment period.

Das Parteiverbot isle von gro^ßerer Wichtigkeit fu¨r den prnventiven Verfassungsschutz, weil es die Absicht hat, die organisierte Verfassungsfeindschaft zu ausschalten. Dies liegt in der Konsequenz der demokratischen Ordnung der Verfassung, die keine Ordnung eines uneingeschra¨nkten Relativismus ist, sondern auf bestimmenten Inhalten beruht, die ihre Offenheit fu¨r unterschiedliche politische Richtungen bedingen und begrenzen. Aber die a¨ußere Sicherung der Verfassungsordnung muß mit dem Preis einer Verku¨rzung politischer Freiheit erkauft werden ; sie tra¨gt die Gefahr einer Verengung des Parteiensystems in sich. Daher ist eine restriktive Auslegung des Parteiverbotsystems geboten. Das Verbot von Parteien in der Verfassung wire anders als das Verbot von sonstigen Vereinigungen regelt. Allein kann das Bundesverfassungsgericht die Verfassungswidrigkeit der Parteien entscheiden ; es entzieht die politischen Parteien dem Zugriff der gesetzgebenden und vollziehenden Gewalt. Dieses Parteienprivileg im Verbotverfahren zielt auf das Schutz der vefassungama¨ßigen Parteien ab. Also bei dem Verbot politischer Parteien muß die positiven Sinne im Parteiverbotsystem erwa¨gt werden.
