A total of 79 Salmonella spp. were isolated from Pusan area in 2000. The serotypes of 79 Salmonella isolates were classified as 42 strains of S. typhi(53.1%), 24 strains of S. enteritidis(30.4%), 9 strains of S. montevideo(11.4%), 2 strains of S. typhimurium(2.5%), 1 strain of S. infantis(1.3%) and 1 strain of S. indiana(1.3%) strains(16.5%) of Salmonella sp. were isolated at May July, respectively. The isolates of S. typhi were sensitive to most sntibiotics except streptomycin. All isolates of S. typhi were especially sensitive to tobramycin, gentamicin, colistin, kanamycin, samikacin, sulfamethozazole/ trimethoprim, cefriaxone, ceftazdime, cifrofloxacin, cefoxitin and cefotaxime. Isolates of S. enteritidis wer presented higher resistance than isolates of S. typhi. Twenty-four strains of S. enteritidis were sensitive to kanamycin, amikacin cifrofloxacin, cefoxitin and cefotaxime, however 13 strains(54.2%) of S. enteritidis were resistant to carbenicillin, ampicillin and ticarcillin. Nine strains of S. montevideo were sensitive to most antibiotics except carbenicillin and streptomycin. Each 1 stain of S. indiana and S. infantis was sensitive to most antibiotics used in this study except streptomycin. Three kinds of resistant pattern (CB, SM, TE, AM, TC). In the case of S. enteritidis isolates, 9 kinds resistant pattern were detected. Most frequent resistant pattern of S. enteritidis isolates was CB, AM, TC type(16.7%)

To clarify the clinical utility of the calvarial bone graft in the maxillofacial reconstruction, we performed on anatomical study by measuring the regional thickness of the parietal bone on 17 Korean adult dry skulls. Before the sectioning the calvarium, the anatomical landmarks were marked on each specimens. And then we measured the total thickness of the parietal bone, the thickness of the outer and inner cortical plates on various points in each sections of parietal bones using a digital caliper under the stereomicroscope. The total thickness of the parietal bone was ranged from 5.17mm to 7.50mm, and there were no statistical difference in the total thickness of the parietal bone on the same points bilaterally. But there was a tendency that the thickness of the parietal bone was thicker toward to the lambda point than the coronal suture area. At the other hand, the thickness of the outer and inner plate of the parietal bone was the thickest at the first point of the right aspect on the line 1, the first point of the left aspect on the line 5, respectively. In conclusion, this study showed that the donor site of the parietal bone for the maxillofacial reconstruction should be located at more posterior and medial area of the parietal bone than the prevalent known donor site.

The studies were conducted to explore the dffects of growth or survival against various factors and plasmid profiles of 49 Y. enterocolitica isolated from springs water. In the presence of calcium hypochlorite, y. enterocolitica was entirely extinguished by exposure for 33 hours at 0.8 ppm concentration, and was grown up to 7% NaCl, but not at 95 NaCI. Y. enterocolitica was presented optimal growth at pH 7.0 anad 9.0, and not allowth the growth at pH3.0, 5.0 and 11.0. The optimal temperature for growth of Y. enterocolitica was 25$\circ$C and 35$\circ$C, and allowed the growth at refrigerant temperature, 5$\circ$C. Y. enterocolitica was remarkably decreased by exposure for 30 seconds under UV light, and entirely extinguished by exposure for 90 seconds. Therefore, UV light was effective for sterilization of Y. enterocolitica. Fourty-nine strains of Y. enterocolitica were harbor plasmid DNA of approximately 46 Kb molecular weight.

These days, systematic lighting design has been required for comfort of the space, unlike past the lighting has been focused on the purpose of illuminating darkness or electric efficiency because at that time we think lighting system was only for darkness. 72% of the customers complain that the color of the cosmetics differs after purchasing. This problem is due to the lack of color rendering for reproduction of colors in store showcase. However, high color rendering lighting equipment has been avoided because of price. This study aims to present a environment that can replace high-priced color rendering lighting system, based on the relationship between level of illumination and color temperature. We measure the level of illumination and color temperature of the 20 cosmetics stores and organize the calculated data. And make customer interviews to find out suitable environment in visual perception. High color rendering property close to nature was secured in 4800Lx and 5500 K. With the lighting environment of the optimum level of illumination and color temperature conditions, concrete design methodology can be realized and applied, especially in general commercial space where is hard to be applied high quality color rendering system because of high price. And also in costume room, design office, museum can be operated in low cost. 조명을 단순히 어두움을 밝히는 목적으로만 인식하여 전기에너지적 효율이나 밝기감 확보에만 집중했던 과거와 달리 공간의 질적 쾌적함을 위한 빛의 체계적 설계가 요구되고 있다. 72%의 고객이 화장품 매장에서 구매한 색조화장품의 색상이 구매이후 달라보여서 불편함을 겪었다고 호소한다. 이 같은 문제는 화장품매장의 색조화장품 쇼케이스의 피부착색테스트용 조명환경에 원색재현을 위한 연색성이 절대적으로 부족하기 때문이다. 하지만 고연색성 조명장비는 높은 가격으로 매장의 관리자나 점주입장에서 적용을 기피하고 있다. 이 연구는 조도와 색온도의 관계성에 의거하여 고가의 고연색성 조명을 대신할 수 있는 빛의 환경을 제시하고자 한다. 이를 위해 서울도심과 부도심의 화장품매장 20곳에 대한 조명환경의 문제를 유형화하였으며 조도와 색온도를 측광하여 산출된 자료를 정리하고, 그 수치에 대한 검증절차로 방문고객을 대상으로 FGI를 실시하여 시지각 인지의 관점에서 적합한 조명조건을 규명하였다. 그 결과, 조도 4800Lx, 색온도 5500 K 의 조건에서 자연광조건에 가까운 높은 연색성을 확보할 수 있었고 매장방문 고객을 대상으로 한 평가조사에서도 이 조건의 연색적정성이 가장 높게 평가되었다. 이 연구를 통해 밝혀진 적정 조도와 색온도조건의 조명환경으로 고연색성 조명장비가 필요하지만 높은 가격 때문에 적용하기 힘들었던 일반 상업공간을 비롯하여 의상실, 디자인사무실, 저예산으로 운영되는 미술관, 박물관, 전시관에서도 합리적 비용으로 쾌적한 시각적 인지환경을 연출할 수 있는 구체적 설계방법론을 구현하고 응용할 수 있게 될 것으로 기대한다.
