Objective : To investigate the efficacy of adjuvant treatment in patients with high-grade meningioma. Methods : A retrospective analysis was performed for patients with high-grade meningioma, World Health Organization grade 2 or 3, in a single center between 2003 and 2014. The patients were reviewed according to age at diagnosis, sex, the location of meningioma, degree of tumor resection, histological features, and type of adjuvant treatment. These factors were analyzed by Firth logistic regression analyses. Results : Fifty-three patients with high-grade meningioma were enrolled. Thirty-four patients received adjuvant treatment; conventional radiotherapy or radiosurgery. Clinical follow-up ranged from 13-113 months with a median follow-up of 35.5 months. Gross total removal (GTR), Simpson grade 1 or 2, was achieved in 29 patients and, among them, 13 patients received adjuvant treatment. In the other 24 patients with non-GTR, conventional adjuvant radiotherapy and radiosurgery were performed in 11 and 10 patients, respectively. The other 3 patients did not receive any adjuvant treatment. Radiation-related complications did not occur. Of the 53 patients, 19 patients had suffered from recurrence. The recurrence rate in the adjuvant treatment group was 23.5% (8 out of 34). On the other hand, the rate for the non-adjuvant treatment group was 57.9% (11 out of 19) (odds ratio [OR]=0.208, p=0.017). In the GTR group, the recurrence rate was 7.5% (1 out of 13) for patients with adjuvant treatment and 50% (8 out of 16) for patients without adjuvant treatment (OR=0.121, p=0.04). Conclusion : Adjuvant treatment appears to be safe and effective, and could lead to a lower recurrence rate in high-grade meningioma, regardless of the extent of removal. Our results might be used as a reference for making decisions when planning adjuvant treatments for patients with high-grade meningioma after surgery.

This study examines the possibilities to improve natural dyestuff's (Pinux$^{TM}$) dyeability and colorfastness for C/R (Cotton/Rayon (40/60)) and W/T (Wool/Tencel (10/90)) knitted fabrics in cationizing and smectiting for pre-treatment, simultaneous-treatment and post-treatment process sequences; as well as various other treatment methods. The sample dyeability showed the strongest K/S value in the order of smectite (S) < cationization + smectite (C+S) < cationization (C); however, the K/S value showed a low level in the simultaneoustreatment method of smectite. Colorfastness to washing improved in the order of C < C+S < S, and after the smectite post-treatment process, C/R improved from Grade 1 to Grade 4 and W/T improved from Grade 1-2 to Grade 4. Colorfastness to perspiration generally improved in the same order as the colorfastness to washing and after the smectite post-treatment process C/R, W/T sample's acidic and alkaline colorfastness to perspiration improved greatly. As for the colorfastness to rubbing, the addition of smectite in the simultaneous-treatment and post-treatment processes resulted in improved wet-colorfastness; however, smectite showed less effect on the colorfastness to light compared to other colorfastness ratings.

Cost-effective purification methods of silicon were carried out in order to replace the conventional Siemens method for solar grade silicon. Firstly, acid leaching which is a hydrometallurgical process was preceded with grinded silicon powders of metallurgical grade (~99% purity) to remove metallic impurities. Then, plasma treatments were performed with the leached silicon powders of 99.94% purity by argon plasma at 30 kW power under atmospheric pressure. Plasma treatment was specifically efficient for removing Zr, Y, and P but not for Al and B. Another purification step by EB treatment was also studied for the 99.92% silicon lump which resulted in the fast removal of boron and aluminum. That means the two methods are effective alternative tools for removing the doping elements like boron and phosphor.

Background: To assess the frequency and severity of gastrointestinal adverse effects in advanced colorectal carcinoma patients treated with four different schedules of FOLFOX. Materials and Methods: Patients (median age 61 years) who underwent surgery were included in the study. All had measureable disease at CT scan, ultrasonography or clinical examination. Toxicity was graded on a scale of 1-5 according to the general grade definition of CTC v2.0. The severity of adverse effects (Grade 3 and 4) assessed in each treatment arm was compared. Results: Differences between the incidence rates of 3 and 4 toxicity and all grades of toxicity for all parameters in GI toxicity were very highly significant (p<0.001). Severe gastrointestinal symptoms of toxicity were noted with FOLFOX7 (oxaliplatin $130mg/m^2$). Grade 3 diarrhea was reported in 25% patients and grade 4 diarrhea in 4% in the FOLFOX7 treatment arm. Grade 2 vomiting was very frequently reported in the FOLFOX4 treatment arm (oxaliplatin $85mg/m^2$). Grade 2 stomatitis was reported in 42% patients treated with mFOLFOX6 (oxaliplatin $100mg/m^2$). Differences in the incidence rate of nausea, diarrhea and stomatitis among all treatment arms of FOLFOX were significant (p<0.05). Conclusions: Severe diarrhea is associated with FOLFOX7 treatment. No grade 3 or 4 GI toxicity was reported in patients of the mFOLFOX6 arm.

Objectives: Primary malignant tumors in the salivary glands are relatively rare. Because of the rarity and the different histopathologic patterns, it is difficult to establish a uniform treatment strategy. The prime treatment of salivary gland malignancy is the surgery, but the role of radiotherapy has been under debate. Radiation therapy combined with conservative surgical procedures may be as successful and perhaps more rational treatment than radical surgery alone. The aim of this study is to evaluate clinical pattern, incidence, treatment modality and outcome of the salivary gland maligancy. Materials and Methods: The medical records of 32 patients with malignant neoplasm of salivary gland who treated at the Keimyung university Dongsan hospital were analyzed retrospectively. Results: The overall 5 year survival rate was 77.9% stage I : 100%, stage II : 75%, stage III : 66.7%, stage IV : 55.6%). The 5 year survival rate according to tumor grade was 100% in low grade malignancy, 71.8% in high grade malignancy. The 5 year survival rate according to treatment modalities was as follows: Surgery only group was 83.3%, combined treatment group with surgery and posoperative radiation was 74.6%. Conclusion: The factors affecting prognosis is variable, but the stage at the time of diagnosis, site of lesion, tumor grade, histologic subtype were important factors. Surgery was the prime treatment tool and postoperative radiotherapy was also imperative in higher stage patient, high grade tumor, or patients with positive surgical margin.

Objectives : This study was designed to evaluate the influence of postauricular pain on Bell's palsy patients. Methods : We investigated 71 cases of patients with Bell's palsy and classified them as existence of Postauricural pain, 71 patients were sequentially interviewed and examined. We evaluated the treatment effect of each group by using Gross Grading System of House-Brackmann(H-B grade) before treatment and after final treatment and we researched differences of sequelae of Bell's palsy, period of treatment, changing point -period from onset of Bell's palsy to the day which the change begins to be seen at the face- and improvement -period which Bell's palsy is improved from onset to H-B gradeII. Results : 1. In age, sex, lesion, duration of disease, we found that two groups have no significant differences. 2. In improvement and period of treatment, we found that two groups have significant differences. In changing-point, we found that two groups had the difference of the average, but they were not statistically significant. 3. As a result of evaluation by using H-B grade, treatment score after final treatment was marked higher than that before treatment within each group. 4. After final treatment, Non-postauricular pain group had significant difference(result) on H-B grade compared with Postauricular pain group. 5. In frequency of sequelae symptoms of Bell's palsy, Postauricular pain group had more higher compared with Non-postauricular pain group. Conclusion : These results suggested that Non postauricular pain group should be get better than Postauricular pain group.
