The disease and insect were surveyed locally in greenhouse, fruit packing house and store house of 51 farms in 13 towns having purpose of paprika exportation. By analysis, various disease and insect were not only founded locally but more ones detected in farms having old facilities and no natural enemy. We found 15 pathogens such as Fusarium spp., Alternaria solani, Leveilluila taurica, PepMV (Pepino mosaic virus) and TMV (Tobacco mosaic virus) in greenhouse, Fusarium spp. in fruit packing house and Penicillium spp. in store house. We found 15 insects in greenhouse such as Bemisia tabaci, rialeurodes vaporariorum and Myzus persicae in greenhouse, Hylobitelus haroldi in fruit packing house. However, the problem quarantine disease and insect for importation and exportation were not detected in inspection time.

After orally administration of a single dose of carbon tetrachloride to rat, the rat was fed the decoctions prepared from Carthami Flos or Leonuri Herba twice at internals of 12 hours. Then, the effects of C. Flos and L. Herba on liver damage was examined. The results were : 1. The decoctions prepared from C. Flos and L. Herba decreased the activities of blood ALT and AST in the damaged rats, and the decoctions prepared from L. Herba increased the glucose level. 2. The decoctions decreased blood LDH activity and blood bilirubin level in the rats. 3. The decoctions prepared from C. Flos and L. Herba and no effects on the blood ALP activity in the rats. 4. The changes of the activities and the levels were not in proportion to the prescribed amount of the decoctions. It needs further study on the optimal dosage.

김두식,정기영,유건룡 혜전대학 1998 論文集 Vol.16 No.-

These days, the scanner systems is one of the electronic products which the speed of development is very fast. It has the inseparable relation to computers, its application has extended to INTERNET. In this paper, we research the its internal structure and the field of the related application regarding the color flat scanner system. Specially we have analyzed its architecture in detail; Opto-Mechanical system, Electronic system, Function block diagram, CAL, VIN Test etc., choose the VISTA-T630 model as a sample. Day by day the computer´s function has been elevated, also the processing technology for the graphics become to diversify. Therefore, many kinds of peripherals have appeared, but our realistic given conditions are inclined to the investment for the field of data communications, disregard that on concerning the image capturing equipments. All of technology can not develop suddenly, so we hope to pave the developing way for the field of scanners by this paer.

Experimental studies were conducted to investigate for the effect of Daeganghwal-Tang(DHT) extract on the anti-inflammatory activity, analgesic activity, subacute toxicity and acute toxicity. The following results have been obtanied ; In the anti-inflammatory activity in rats, DHT extract (300,600㎎/㎏ p.o) was shown remarkable preventive effect in the edema induced by Freund's complete adjuvant and 5% acetic acid. In analgesic activity test in mouse, DHT extract(300,600㎎/㎏ p.o) was shown significant analgegic activity in mouse induced by 0.7% acetic acid. In acute toxicity test in mouse, DHT extract showed10% mortelity at DHT extract 1.200㎎/㎏ i.p. and 2,000㎎/㎏ p.o.. In subacute toxicity test in mouse. DHT extract was not showed toxicity for 19 day. Uric acid in the serum of the treated rats by Freund's complete adjuvant were slightly decreased by comparing with the control group. During the administration of DHT extract, The body weight increased, but the liver and spleen weight was not changed by comparing with the control group. .

22Cr-5Ni 2상 스테인리스강의 합금원소 중 몰리브덴(Mo) 원소를 텅스텐(W)으로 치환하여 크리프거동에 미치는 영향을 조사하였다. 크리프시험은 600℃와 650℃의 온도에서 실시하였다. 650℃ 크리프 시에는 취약한 금속간화합물인 σ상이 석출하였으며 이것은 크리프수명을 급격히 감소시키는 역할을 하였다. Mo에 대한 W원소의 치환은 일반적으로 σ상의 석출을 지연시킨다고 알려져 있으나, 2wt.%까지 W 치환을 실시한 본 연구범위에서는 크리프 수명 및 최소 크리프속도에 뚜렷한 영향을 미치지 못하였다. 크리프손상의 정도를 평가하기 위하여 크리프시편에 대한 초음파검사를 실시하였다. 크리프온도 600℃에서는 크리프시편의 수명이 증가함에 따라 음속이 비례적으로 증가하였으나 650℃에서는 반대로 감소하였다. The effect of the substitution of Tungsten(W) for Molybdenum(Mo) on the creep behaviour of 22Cr-5Ni duplex stainless steel(DSS) has been investigated. Creep tests were carried out at 600℃ and 650℃. Intermetallic σ phase is precipitated during creep at 650℃, at which creep rupture time was much lower compared with at 600℃. The substitution of W for MO in the duplex stainless steel was known to retard the formation of σ phase. Minimum creep rate and creep rupture time, however, were hardly influenced by the substitution of 2wt.% W. An ultrasonic measurement for the creep specimens has been carried out for the evaluation of creep damage. The sound velocity increases propotionally with the increase of creep rupture time at 600℃ of creep temperature. On the contrary, the sound velocity decreases with the increase of rupture time at 650℃, which can be correlated with the microstructural evolution during creep.

Although, the GPS using for user location tracking has many advantages of chasing the target in a wide area, the GPS has defect as is isn't able to chase the location in doors or basements. To make up for it's defect, we need to use the UWB signal. The UWB has not a very wide bandwidth, but low signal level under noise level and it can pass through a wall. In this report, using the time delay we simulate indoor position tracking system to chase a user among people in a building when signal is in progress

Bacillus thuringiensis is a gram-positive soil bacterium characterized by its ability to produce crystalline inclusions during sporulation. These parasporal bodies consist of protoxins known as crystal proteins exhibiting highly specific insecticidal activities. The Lepidoptera-specific protoxin, Cry IAc, was purified from E.coli JM103 harboring the cry IAc gene. The gene was isolated from Bacillus thuringiensis kurstaki HD-73 and subcloned into an expression vector, pKK223-3. The recombinant DNA(pOS4201) was transformed into E.coli JM103. The Cry I Ac protoxin overexpressed in the E.coli was isolated from the total proteins by differential solubility. The protoxin were trypsinized to obtain activated toxin. The proteins was resolved on SDS gel. The molecular weights of the pro-and toxin were resistered about 130,000 and 65,000 Daltons respectively. The Cry IAc toxin was used as immunogen to produce anti-Cry IAc antiserum in a rabbit. The immunogen (200㎍/ 200㎕) was mixed with an equal volume of Freund's complete adjuvant, and the mixture was hypodermically injected to the hide back (30 spots) and paws (2 spots) of the rabbit. The immunization was performed four times every two weeks. The dosage of the immunogen was decreased by half, and incomplete adjuvant was substituted for the complete one from the second immunization. The serum was prepared from the blood as described elsewhere. Immunoreactivity of the serum was examined by dot-blotting with the aid of GAR-HRP indirect immunoassay kit. It has been found that the anti-Cry I Ac antiserum recognized nano-gram quantity of antigen under these experimental conditions. The antiserum will he used for the development of immunochemical mean(s) to screen transgenic plants transformed by the insecticidal characteristics of Cry I Ac.

This study is intended to describe and suggest the future available services by using the ability of estimating position with submeter error, which is provided by National Differential Global Positioning System(NDGPS). Such countries as Japan, Australia, Europe, and the United States have reviewed various applications for DGPS services with high accuracy of submeter level. In Korea, many researchers have found applications usable by NDGPS. Korea government is also seeking for applications to efficiently utilize NDGPS services as a national infrastructure. We suggest Global Navigation Satellite Services(GNSS) position services with high accuracy by investigating technologies with relation to a national R&D strategy in the field of Information Technology(IT) and Marine Technology(MT). The suggested services would help expand the future applications for NDGPS.
