The purpose of this study was to evaluate skeletal and soft tissue changes that occur after using a facemask for treatment of skeletal class III malocclusion, and to assess the relapse pattern when no retention appliance was used. Fifteen skeletal class III malocclusion patients were treated with a facemask for an average of 12 months. No retention appliance was used during the 1 year follow-up period. Cephalograms were taken during pretreatment, posttreatment, and the 1 year follow-up. Cephalograms were traced, analyzed, and the results were compared between cephalograms. All patients showed significant sagittal skeletal changes after treatment, but they also showed a significant relapse during the 1 year follow-up period when no retention appliance was used. Despite the relapse, the sagittal skeletal changes that remained were still significant. Vertical skeletal change was also significant after treatment, but the total change was not significant after a 1 year follow-up due to relapse. In soft tissue changes, facial convexity and upper lip position improved after treatment and this change remained significant after the 1 year follow-up period. Facemask therapy is therefore an effective method for treatment of skeletal class III malocclusion, however, retention is imperative to maintain the treatment effect.

A most appropriate model of 3-D conformal radiotherapy has been induced by clinical evaluation and animal study, and therapeutic gains were evaluated by numerical equation of tumor control probability(TCP) and normal tissue complication probability (NTCP). The radiation dose to the tumor and the adjacent normal organs was accurately evaluated and compared using the dose volume histogram(DVH). The TCP and NTCP was derived from the distribution of given dosage and irradiated volume, and these numbers were used as the biological index for the assessment of the treatment effects. Ten patients with liver disease have been evaluated and 3 dogs were sacrificed for this study. Based on the 3-D images of the tumor and adjacent organs, the optimum radiation dose and the projection direction which could maximize the radiation effect while minimizing the effects to the adjacent organs could be decided. 3). The most effective collimation for the normal adjacent organs was made through the beams eye view with the use of multileaf collimator. When the dose was increased from 50Gy to 70Gy, the TCP for the conventional 2-port radiation and the 5-port multidimensional therapy was 0.982 and 0.995 respectively, while the NTCP was 0.725 and 0.142 respectively, suggesting that the 3-D conformal radiotherapy might be the appropriate therapy to apply sufficient radiation dose to the tumor while minimizing the damages to the normal areas of the liver. Positive correlation was observed between the NTCP and the actual complication of the normal liver in the animal study. The present study suggest that the use of 3-D conformal radiotherapy and the application of the mathematical models of TCP and NTCP may provide the improvements in the treatment of hepatoma with enhanced results.

The purpose of this study is to analyze regional variation factors of hypertension treatment rate in COVID-19 based on the analysis results based on ecological methodology. To this end, data suitable for ecological analysis were collected from the Korea Centers for Disease Control and Prevention's regional health statistics, local government COVID-19 confirmed cases, National Health Insurance Corporation, Health Insurance Review and Assessment Service's welfare statistics, and Korea Transport Institute's traffic access index. Descriptive statistics and correlation analysis were conducted using SPSS Statistics 23 for regional variation and related factors in hypertension treatment rate, and geographical weighted regression analysis was conducted using Arc GIS for regional variation factors. As a result of the study, the overall explanatory power of the calculated geo-weighted regression model was 27.6%, distributed from 23.1% to 33.4% by region. As factors affecting the treatment rate of hypertension, the higher the rate of basic living security medical benefits, diabetes treatment rate, and health institutions per 100,000 population, the higher the rate of hypertension treatment, the lower the number of COVID-19 confirmed patients, the lower the rate of physical activity, and the alcohol consumption. Percentage of alcohol consumption decreased due to COVID-19 pandemic. It was analyzed that the lower the ratio, the higher the treatment rate for hypertension. Based on these results, the analysis of regional variables in the treatment rate of hypertension in COVID-19 can be expected to be effective in managing the treatment rate of hypertension, and furthermore, it is expected to be used to establish community-centered health promotion policies.

This study was conducted to identify the mediating effects of the therapeutic relationship with mental health professionals between empowerment and recovery in mental illness. The participants were 168 adults in two community mental health centers and three rehabilitation centers in Jeonbuk. The data were collected by structured questionnaires from April 15 to April 30, 2015 and analyzed using descriptive statistics, Pearson's correlation coefficient, and multiple regression analysis with the SPSS 19.0 statistical program. The mean score of empowerment for mental illness, recovery and therapeutic relationship were $60.4{\pm}10.85$, $101.8{\pm}20.70$ and $74.5{\pm}14.30$, respectively. There were significantly positive correlations between recovery in empowerment and therapeutic relationship (r=0.33, p<0.001), as well as empowerment and recovery (r=0.51, p<0.001), while there were significantly positive correlations between therapeutic relationship and recovery (r=0.55, p<0.001). Therapeutic relationship had a partial mediated effect between empowerment and recovery, which was found to be significant by the Sobel test (z=3.706, p<0.001). The results of this study can be used as basic data for development of a practical recovery-enhancing program to promote therapeutic relationships and improve empowerment in relation to therapist of the mentally disabled.

A 70-year-old female diagnosed with pancreatic ductal adenocarcinoma was treated by pylorus-preserving pancreaticoduodenectomy (PPPD) and adjuvant concurrent chemoradiotherapy with 5-fluorouracil. Pancreatic ductal adenocarcinoma pT3N0 (stage IIA) was pathologically confirmed. Abdominal computed tomography (CT) findings 14 months after PPPD showed 10 mm sized solitary liver metastasis in segment 3. After 12 cycles of gemcitabine and 9 cycles of capecitabine plus oxaliplatin, the metastatic nodule increased in size to 27 mm. Tumorectomy at segment 3 of liver was done. 25 months after tumorectomy, chest CT showed 23 mm sized cavitary nodule in right upper lobe of lung. The result of percutaneous biopsy favored metastatic adenocarcinoma. Two sets of stereotactic body radiation therapy were done and the patient has survived without further disease progression for 6 years after initial diagnosis. This case suggests that selected population of recurrent pancreatic cancer patients with solitary liver or pulmonary metastasis can be treated by resection of metastatic site and ablative therapies.

Rotator interval should be as loose as possible, though not so loose as to break the shoulder mechanism. This region is a source of significant shoulder pathology resulting in patient discomfort and dysfunction. The clinical features fall into two categories. Rotator interval tightness is associated with impingement, contracture with adhesive capsulitis, and widening with anteroinferior, posterior or multidirectional instability. Coracoid impingement can cause damage to the structures of the rotator interval, Injury of the interval are associated with subscapularis tears as well as biceps tendinitis, fraying, subluxation, and dislocation. An understanding of the normal and pathologic anatomy can lead to successful diagnosis and treatment of lesions in the rotator interval.
