저자들은 간이식을 받은 환자에서 조직 배양 검사를 통하여 진단된 A. fumigatus에 의한 화농성 고관절염을 경험하였기에, 문헌 고찰과 함께 보고하는 바이다. Septic arthritis is an uncommon finding of invasive Aspergillosis. It can be caused by direct inoculation, Post-surgical infection, and hematogenous spread. Articular aspergillosis often involves the knee. A 49-year-o1d man who received a liver transplant in China on two months ago, due to liver cirrhosis caused by hepatitis B virus was admitted because of left side hip pain. Hip MRI showed joint effusion and bony destruction of the left hip and acetabulum. Incision and drainage was done and Aspergillus fumigatus was isolated from the resected tissue. After eight weeks of amphotericin B therapy, total hip replacement arthroplasty was done. Oral itraconazole 400mg/day was prescribed for six months after operation. The patient is now doing well without physical restriction.

배추좀나방과 유충기생봉인 프루텔고치벌에 대한 살충제의 독성을 비교한 결과는 다음과 같다. 프루텔고치벌에 기생당한 배추좀나방의 유충은 fenvalerate, pyraclofos, spinosad와 chlorfluazuron의 충체침지 또는 엽침지시에 정상유충보다 현저히 감수성이 높았다. 그러나 Bacillus thuringiensis는 엽침지시에만 기생당한 유충에 독성이 약간 강하였다. Fenvalerate, pyraclofos와 spinosad의 잔류독은 배추좀나방 성충보다 프루텔고치벌 성충에 훨씬 독성이 강하였다. 그러나 chlorfluazuron과 B. thuringiensis의 경우는 두 종의 성충에 모두 별 영향이 없었다. 따라서 B. thuringiensis는 배추좀나방의 종합관리에서 프루텔고치벌에 직접적인 영향이 없이 사용할 수 있을 것으로 사료된다. The relative toxicity of some insecticides to diamondback moth, Plutella xylostella and larval parasitoid, Cotesia plutellae was evaluated. Diamondback moth larvae parasitized by C. plutellae were significantly more sensitive to fenvalerate, pyraclofos, spinosad and chlorfluazuron than nonparasitized larvae through direct dip- or leaf dip assay. However, Bacillus thuringiensis was slightly more toxic to parasitized larvae through direct dip bioassay. The residual toxicity of fenvalerate, pyraclofos and spinosad was significantly more toxic to C. plutellae adults than to P. xylostella adults. However, chlorfluazuron and B. thuringiensis have no serious effect to adults of C. plutellae and P. xylostella. These results suggest that B. thuringiensis could be used in integrated management of P. xylostella without direct effect on C. plutellae.

배추좀나방의 유충 기생봉인 프루텔고치벌의 기생특성에 대해 조사한 결과는 다음과 같다. 프루텔고치벌은 배추좀나방 유충의 모든 영기에 기생하였으나, 주로 2령과 3령충을 선호하였다. 온도별 프루텔고치벌은 배추좀나방 유충에 대한 기생율은 18, 20, 25, 30℃에서 각각 41.9, 66.0, 86.0, 68.7%였다. 프루텔고치벌은 배추좀나방 유충의 밀도가 증가함에 따라 기생수는 증가하나 그 증가율은 감소하는 Holling의 제2형(포화형) 기능반응을 나타내었다. This experiment was conducted to investigate the parasitic characteristics of Cotesia plutellae Kurdjumov, a larval parasitoid of Plutella xylostella L. Although C. plutellae parasitized all 4 instars of P. xylostella, it parasitized mainly the second and third instars. Parasitisms of C. plutellae at different temperatures were 41.9, 66.0, 86.0, and 68.7% at 18, 20, 25, and 30℃, respectively. The parasitic response curve of C. plutellae to the host density indicated Holling' type Ⅱ(saturation type) functional response: the parasitism of host by C. plutellae increased with the host density but the parasitic rate decreased.

Cubitus varus deformity is the late complication of the supracondylar fracture of humerus which is common in growing children. If the deformity is severe it cause functional problems as well as cosmetic ones necessitating corrective osteotomy. Though many authors devised different method of corrective osteotomy, the cosmetic results are not always satisfactory because of the development of "the lasy S" deformity by the lateral prominence. Technically, the initial stability of the osteotomy is also poor due to the poor contact of the osteotomy site. So we have devised a new quadrilateral displacement osteotomy to increase the initial stability of the osteotomy by creating a wedge on the osteotomy site and also to prevent the development of "the lasy S deformity" by elimination of the lateral prominence. We treated 3 cases of cubitus varus defomity with the new quadrilateral displacement osteotomy. The correction was not difficult and the initial stability of the osteotomy is rather good and the osteotomy is fixed by the convential methods, and the osteotomy were healed uneventfully. There developed no "the lasy S deformity" after osteotomy. We would like to report the details of the supracondylar quadrilateral displacement osteotomy.
대전광역시 양축농가의 축분뇨 관리 실태 및 VOCs 농도 조사

This study was carried out to investigate the style of livestock house, concentration of malodorous substances of livestock feces and livestock houses in Daejeon area. Among the livestock houses investigated, as most of cow pens(94.5%) have sawdust or chaff on the bottom, there was no leakage of feces out of pen. Most pig pens adopted slury style, but some of them currently use buffering material on the bottom. It is thought that there will be no possible contamination leakage. When it comes to hen house, all the broiler house use litters on the bottom and all the layer house use scrapper. It is also thought that there will be no possible contamination leakage. 3 out of 12 deer pens used buffering material on the bottom, 10 places were maintained in a traditional method, and 7 places left possibility of contamination leakage considering whether the roof was installed or not. The contents of ammonia, amine and volatile fatty acid in fresh feces were lower compared to rotten feces, but the concentration of sulfur-containing matter - hydrogen sulfide, methylmercapthan and ethylmercapthan were higher compared to rotten feces. In the case of malodorous ingredient in livestock houses, only small amount of ammonia and hydrogen sulfide were detected in pig pen and hen house, and other ingredients were not detectable. And those who are engaged in animal husbandry reacted negatively to the use of feed additives for decreasing malodor. In conclusion, it is not worrisome that contamination can be leaked out of animal raising facilities. But if we take into consideration that the point of investigation time is wintry season, there should be more considerate attitude. And feed additives for decreasing malodor need establishing criteria in the manufacturing process.

<P>This paper reports the possibility of a facile optical structure to realize a highly efficient monochromatic amber-emitting light-emitting diode (LED) using a powder-based phosphor-converted LED combined with a long-wave pass filter (LWPF). The capping of a blue-reflecting and amber-passing LWPF enhances both the amber emission from the silicate amber phosphor layer and the color purity due to the blocking and recycling of the pumping blue light from the InGaN LED. The enhancement of the luminous efficacy of the amber pc-LED with a LWPF (phosphor concentration 20 wt%, 39.4 lm/W) is 34% over that of an amber pc-LED without a LWPF (phosphor concentration 55 wt%, 29.4 lm/W) at 100 mA and a high color purity (>96%) with Commission International d'Eclairage (CIE) color coordinates of x=0.57 and y=0.42.</P>
