Midfacial degloving approach의 장점으로는 비강, 비중격, 상악동, 사골동, 접형골동, 비인두 부위 병소의 접근에 좋은 시야를 제공하며, 수술방법이 기존의 방법에 비해 수월하고, 두피관상 절개법, 측두부 절개법, 구개부 절개법과 함께 사용하여 수술시야를 넓힐 수 있으며, 안면부에 나타나는 흉터가 없어 심미적으로 만족스러우며 특히, Keloid 체질에서 유용하다는 것을 들 수 있다. 이에 저자 들은 구강악안면외과 영역에서도 중안면부 외상, 두개안면부 기형 처치, 상악골 절제술을 요하는 경우, 상악골과 비골의 동시 수술을 요하는 경우 등에 midfacial degloving approach가 유용한 수술 접근 방법으로 사료되었다. In the treatment of maxillary lesion including a maxillary sinuses, most of oral and maxillofacial surgeons have used the vestibular incision or the Weber-Fergusson incision. However, the vestibular incision has disadvantage which it provides a rather limited exposure and the Weber-Fergusson incision leaves visible scar in the midface. Furthermore, because the scar is confined on unilateral side only, the technique is hesitated to apply especially in children, younger patients and women. Since Casson first introduced midfacial degloving technique, this approach has been used frequently to treat the lesion on nasal cavity, nasopharynx, skull base and paranasal sinuses by ENT surgeons. But, we think this technique can be used usefully in oral and maxillofacial regions. So, we experienced favorable results which it provided a proper exposure, no visible facial scar and it could be used on bilateral midfacial lesions.

As hepatocellular carcinoma metastases well to distant site, half of the cases metastases to distant site at diagnosis. However hepatocellular carcinoma metastasis to oral cavity, especially gingival metastasis, is very rare and only 25 such cases were reported so far. This is the first reported case of hepatoma metastasis to the gingiva in Korea. Although the prognosis of the hepatocellular carcinoma was very poor in the past, the survival time seemed to be prolonged by early diagnosis and improvement of medical therapy. Therefore the importance of metastatic lesion of the hepatocellular carcinoma might be reemphasized. We recently experienced a case of hapatoma metastasis to the gingiva.

The purpose of this study was to explore the effect on isokinetic muscle function and performance according to the level of Revolutions Per Minute (RPM) during bowling pitching for male professional ten-pin bowlers. For this, we experimented with 14 professional ten-pin bowlers over the age of 20. We measured the average value of RPM during bowling pitches in 4 games. We conducted isokinetic muscle function tests by splitting into a high RPM group and a low RPM group based on the median split-half method. The collected data was analyzed using SPSS 23.0, and the difference between each group was analyzed by applying an independent t-test. The results of the study are as follows. First, there was a statistically significant difference between the groups in the knee peak torque at 180°/sec and 240°/sec Flexor BW(R). Also, there was a statistically significant difference between the groups in the waist peak torque at 60°/sec, 180°/sec, and 240°/sec Extensor BW. Lastly, there was no statistically significant difference between the groups in the scoring according to RPM level. 본 연구는 남자 전문 볼링선수를 대상으로 볼링 투구 시 볼의 분당 회전수(Revolutions Per Minute, [RPM]) 수준이 등속성 근기능과 경기력에 미치는 영향을 탐색하기 위한 목적으로 진행되었다. 이러한 목적에 따라 20세 이상의 전문 볼링선수 14명을 대상으로 연구를 진행하였다, 4게임의 볼링 투구에서의 볼의 분당 회전수의 평균값을 측정하였으며, 중앙치 반분법을 준거로 분당 회전수 상위집단(High RPM Group)과 분당 회전수 하위집단(Low RPM Group)으로 집단 편성하여, 등속성 근기능 검사를 실시하였다. 수집된 자료는 SPSS 23.0을 이용하여 분석하였으며, 각 집단 간에 차이는 독립 t검정을 적용하여 분석한 연구결과는 다음과 같다. 첫째, 볼링 투구 시 분당 회전수 수준에 따른 전문 볼링 선수들의 무릎 최대우력의 차이는 180°/sec, 240°/sec Flexor BW(R)에서 집단 간에 통계적으로 유의한 차이가 나타났다. 둘째, 등속성 허리 최대 우력 차이는 60°/sec, 180°/sec, 240°/sec Extensor BW에서 집단 간에 통계적으로 유의한 차이가 나타났다. 셋째, 볼링 투구 시 RPM에 따른 점수 기록의 차이에서 통계적으로 유의한 차이가 나타나지 않았다.

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.

Three and 2 strains of E coli O157 were isolated from fecal materials of cattle (390) and pigs (420) in Korea, respectively. One strain of O157:H7 isolated from cattle and 2 strains of O157:H7 isolated from pigs were identified as verotoxin-1 (VT-1) produing strains and 2 strains (O157:H7 and O157:H-) isolated from cattle were identified as verotoxin-2 (VT-2) producing strains by neutralization test on HeLa and Vero cells. Culture supernatants of the isolates were cytotoxic to HeLa and Vero cells. The levels of cytotoxin produced by isolates were $10^2{\sim}10^4$ cytotoxic dose($CD_{50}$)/ml. Also, VT-2-converting bacteriophage was isolated from KSC109 strain which had been isolated from cattle. Molecular weight of the phage DNA was determined as approximately 45 Kb in 0.8% agarose gel electrophoresis, and morphology of the phage stained with phosphotungstic acid was observed by transmissible electron microscopy.

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.
