  • 본 연구의 주요 목적은 서로 다른 측지기준계인 동경측지계와 세계측지계간의 좌표 변환을 위한 연구이다. 이를 위하여 Bursa-Wolf 모델, Molodensky-Badekas 모델 및 Veis 모델을 이용하여 7변환 계수를 결정하였다. 또한 동경데이텀으로부터 세계측지계로 변환하기 위한 다중회귀식 방법도 적용하였다. 공통점 중에서 비상사성인 과대 오차인 점을 분석하고 제거하여 935점의 국가기준점 성과를 변환 계수 결정을 위한 공통점으로 이용하였다. 각 모델별로 결정한 변환 계수를 적용하여 상사 변환에 의한 3, 4등 삼각점 9,917점에 대한 좌표변환을 수행하였으며 변환 정확도를 평가하였다. 그 결과, Bursa-Wolf 모델과 Molodensky-Badekas 모델을 이용하여 결정한 변환 계수가 Veis 모델에 비하여 더 적합하다는 것을 알 수 있었다. 다중회귀식에 의한 변환 정확도는 상사 변환 모델보다는 다소 저하되는 경향을 보였다. 변환 계수의 추정 정밀도와 변환 정확도 및 변환 잔차의 패턴을 분석한 결과, 최적의 국가 좌표변환 모델은 Molodensky-Badekas 모델이라고 판단된다.

  • Purpose: Ischial region is common site of pressure sore as well as greater trochanteric area. In general, ischial pressure sore associated with a large subcutaneous bursa often requires radical surgical treatment. The authors performed sclerotherapy using absolute ethanol which was considered as an alternative in treating recurrent ischial pressure sore. Methods: From may 2005 to February 2006, 11 ischial pressure sore patients were treated sclerotherapy using absolute ethanol. The authors performed sclerotherapy using absolute ethanol in 11 patients in whom the ischial sore has recurred despite of multiple radical surgical treatment. The patients' original disorders were spinal cord injury in 9 patients, cerebral palsy in 1 patient and giant cell tumor in thoracic vertebrae 1 patient. Results: Recurrence of pressure sore was not found in any patient during the follow-up period. The swap of the bursa taken before the surgery was germ cultured and compared with the discharge from an end of the inserted drain tube. The germ cultured results after the surgery were tested negative in all patients. Conclusion: This method involves causing the bursa to become scarred and closing it up by sterilizing, fixing, and denaturing by the pharmacologic effect of absolute ethanol instead of surgical excision of the bursa. We felt that aforementioned treatment modality may be considered as an alternative in treating recurrent ischial pressure sore.

  • This experiment was performed to investigate apoptosis during undergoing pathogenesis of avian infectious bronchitis virus(IBV)-infected chicks. Sixteen days old chicks were infected with IBV, Massachusetts-41 strain(M-41, 10$^4$-10$^{5}$ EID$^{50}$ ) experimentally, they were autopsied to remove trachea, lung, kidney and cloacal bursa at 6hr, 12hr, 1 day, 3 day and 7 day post infection(PI) respectively for H-E and TUNEL staining. Grossly, mild serous, catarrhal exudate was observed in the trachea, nasal passages and sinuses nasal from 4 day PI. The cloacal bursa was swollen from 3 day PI. Histopathologically, the trachea was seen mild cellular infiltration, edema of the mucosa and submucosa, vascular congestion and mild hyperplasia of the epithelium from 6 hr PI and the changes were seen a little more severely on 7 day PI. It was observed that the cloacal bursa was getting more and more hyperplasia through the experiment. The nuclei degeneration were shown in the kidney on 7 day PI. No specific changes were seen in the lung. In TUNEL analysis, apoptotic cells showed sharp increasing at 12 hr PI and reaching a maximum on 1 day PI in the trachea, lung, kidney and cloacal bursa. And then apoptotic cells decreased gradually returning to a level of the control by 7 day PI in all the removed organs.

  • Purpose: To evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic lateral malleolar bursitis. Materials and Methods: Thirteen cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 16.4 months. The average symptom duration before introduction into this study was 7.8 weeks. With an aseptic technique, the aspiration of the bursa was done with 18G needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was identified two or three times in a week and stitch out was done at the cessation of drainage. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture was found in all cases, but there was no development of active infection or recurrence. The average duration of treatment is 10.4 days. Conclusion: The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic lateral malleolar bursitis.

  • A superoxide anion radical scavenger isolated from Capsella bursa-pastoris was characterized by infrared (IR) spectroscopy, sugar analysis, ultraviolet (UV) spectroscopy, $^{1}H$ and $^{13}C$ nuclear magnetic resonance (NMR) spectroscopies, and fast atom bombardment (FAB) mass analysis. The compound was assumed to be a flavonoid-O-glycoside from IR spectrum and UV absorption maxima. When the sugar composition of the compound was examined by thin layer chromatography (TLC) and gas chromatography (GC) of the acid hydrolysate, only glucose was detected. According to the results of UV spectrotroscopy by using shift reagents, the compound was supposed to be luteolin (5,7,3',4'-tetrahydroxy flavone) or chrysoeriol (5,7,4'-trihydroxy-3'-methoxy flavone) with glucose. Based on $^{1}H$- and $^{13}C-NMR$ spectroscopies, the compound was deduced as 7,4'-dihydroxy-5,3'-dimethoxy-${\alpha}$-6-c-glucosyl-${\beta}$-2"-o-glucosyl flavone. In FAB mass analysis the compound was finally characterized as 7,4'-dihydroxy-5,3'-dimethoxy-${\alpha}$-6-c-glucosyl-${\beta}$-2"-o-glucosyl flavone ($C_{29}H_{34}O_{16}$, M.W.=638).

  • The purpose of this study was to evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic olecranon bursitis. Eleven cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 17.5 months. The average symptom duration was 1.8 months. With an aseptic technique, the aspiration of the bursa was done with 18gauge needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was regularly checked $2{\sim}3$ days interval and stitch out was done at the cessation of drainage. At the follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Redness around the insertion site of silk suture was found in all cases, but there was no active infection or recurrence. The results were satisfactory in all cases and the average time for recovery was 10.5 days. The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic olecranon bursitis.

  • The study investigates the association between the effectiveness of the board of directors and the likelihood that a company receives a modified audit opinion (as a measure of the quality of companies' external financial reporting) in Malaysia. The sample companies were extracted from the population of publicly-available information mainly the annual reports of publicly-listed companies on the Bursa Malaysia. 136 firm-year observations listed on Bursa Malaysia were identified to examine the relationship between the effectiveness of the board of directors and a modified audit opinion. Data used in this study are collected from two separate sources - annual reports and Datastream. Any missing financial figure from Datastream was acquired from the annual reports. To test the study's hypotheses, we use the pooled cross-sectional logistic regression analysis for 136 firm-year observations listed on Bursa Malaysia over the period 2009-2011. The evidence we have uncovered is consistent with the hypothesis that companies with large score of the board of directors' effectiveness are less possible to receive a modified audit opinion. Therefore, the result confirms that the combined effect of the board of directors' characteristics has a significant negative association with the likelihood of the companies receiving a modified audit opinion.
