The main purpose of this study is to investigate the coordinate transformation based on two different systems between local geodetic datum(tokyo datum) and international geocentric datum(new Korea geodetic datum). For this purpose, three methods were used to determine seven parameters as follows: Bursa-Wolf model, Molodensky-Badekas model, and Veis model. Also, we adopted multiple regression equation method to convert from Tokyo datum to KTRF. We used 935 control points as a common points and applied gross error analysis for detecting the outlier among those control points. The coordinate transformation was carried out using similarity transformation applied the obtained seven parameters and the precision of transformed coordinate was evaluated about 9,917 third or forth order control points. From these results, it was found that Bursa-Wolf model and Molodensky-Badekas model are more suitable than other for the determination of transformation parameters in Korea. And, transforming accuracy using MRE is lower than other similarity transformation model.

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.

Volatile flavor components from various edible portions of Capsella bursa-pastoris were collected by simultaneous steam distillation-extraction (SDE) method using diethyl ether as solvent. Essential oils were analyzed by gas chromatography (GC) and combined gas chromatography-mass spectrometry (GC-MS). Thirty four volatile flavor components, including 12 hydrocarbons, 2 aldehydes, 2 ketones, 5 alcohols, 1 ester, 10 acids and 2 miscellaneous ones were confirmed in whole samples. Thirty one components, including 11 hydrocarbons, 5 aldehydes, 4 ketones, 5 alcohols, 1 esters and 5 miscellaneous ones were confirmed in leaves. Twenty four components, including 5 hydrocarbons, 1 aldehyde, 2 ketones, 6 alcohols, 2 esters, 1 acid and 7 miscellaneous ones were confirmed in roots. The kinds and amounts of volatile flavor components revealed different patterns depending upon various edible portions. Relatively greater numbers of volatile flavor components were identified in leaves compared with roots of these wild plants. The characteristic aroma of Capsella bursa-pastoris appeared to be due to combination of C6 alcohol and acids, terpene alcohol and sulfur containing compounds.

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.

We treated a 37-year-old male with traumatic hematoma in the suprapatellar bursa that had developed in the form of persistent swelling on suprapatellar area of left knee after blunt trauma. Though there were no obvious abnormal findings on plain roentgenographs, an isolated suprapatellar cystic lesion with fluid-fluid level on T2-weighted sagittal image of MRI was noted. We found the suprapatellar plica with complete septum and no synovitis in the knee joint proper by arthroscopy. We incised the plica and found leakage of blood-stained fluid from the suprapatellar bursa. There were no findings of pigmented villonodular synovitis or other tumorous lesions. At 6 months after surgery, the patient felt symptom-free and there was no recurrence.

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.
