Subclavian vein injuries occasionally occur as a sequela of penetrating trauma or vascular access, but have rarely been reported to occur after clavicle fracture. The subclavian vessels are mainly enclosed by the subclavius muscle, the first rib, and the costocoracoid ligament. Therefore, in such cases, subclavian vein injury is rare because of the strcutures surrounding the subclavian vessels. Nevertheless, subclavian vein injuries occasionally show thrombotic manifestations, and thrombosis of the upper limbs constitutes 1-4% of cases of total deep vein thrombosis. Furthermore, to the best of the authors' knowledge, although vessel injuries have been reported after clavicle or rib fractures and nerve injuries to regions such as the brachial plexus, no case involving delayed presentation of isolated subclavian vein stenosis after clavicle fracture due to blunt trauma has yet been reported.

Purpose: This study was conducted to examine differences in health care utilization and related costs between before and after the introduction of the designated doctor system, and to find out factors making the differences. Methods: Data were collected from 200 medical aid beneficiaries having one or more chronic diseases, registered in the designated doctor system during the year of 2012, and the relationship between the use of health services and claimed medical expenses was analyzed through paired t-test and multiple regression analysis using the SPSS 18.0 program. Results: There was a decrease in the number of total benefit days and the number of outpatient and medication days, but some cases showed an increase after the designation of medical institution. In general, hospital stay increased after the introduction of the system. However, the number of medical institutions utilized was reduced in most cases after designation. Conversely, medical expenses increased in most cases after the designation of medical institution. Conclusion: These results suggest that a detailed scheme to designate medical institutions should be made in consideration of the seriousness of illness and classification of medical institutions not only for the beneficiaries' enhanced health but for the effective management of medical aid fund.

PURPOSE. The aim of this study was to compare the surface roughness of zirconia when using Zircos E etching system (ZSAT), applying a nitric acid-hydrofluoric acid compound as a pretreatment agent, and also to compare the shear bonding strength according to different resin cements. MATERIALS AND METHODS. ZSAT, air abrasion, and tribochemical silicacoating were applied on prepared 120 zirconia specimens (10 mm in diameter, 7 mm in height) using CAD/CAM. Each 12 specimens with 4 different resin cements (Panavia F 2.0, Rely X Unicem, Superbond C&B, and Hot bond) were applied to test interfacial bond strength. The statistical analysis was performed using SAS 9.1 (SAS Institute Inc., Cary, NC, USA). The results are as follows: after application of the ZSAT on the zirconia specimens, surface roughness value after 2-hour etching was higher than those after 1- and 3-hour etching on SEM images. RESULTS. For Superbond C&B and Rely X Unicem, the specimens treated with ZSAT showed higher shear bond strength values than those treated with air abrasion and tribochemical silicacoating system. Regarding the failure mode of interface over cement and zirconia surface, Rely X Unicem and Hot bond showed cohesive failures and Panavia F 2.0 and Superbond C&B showed mixed failures. CONCLUSION. Zircos E etching system in zirconia restoration could increase its shear bond strength. However, its long term success rate and clinical application should be further evaluated.

Extramedullary plasmacytoma (EMP) is a rare disease that occurs in 3% to 5% of patients with plasma cell disorder. It occurs most commonly in the upper respiratory tract and the oral cavity. Very few EMP cases have been reported in the central nervous system (CNS). We report herein an unusual case of EMP in the nasal cavity that recurred in the CNS without systemic involvement. A 67-year-old man visited our hospital due to a month-long bout with exophthalmos. He was diagnosed with EMP in the nasal cavity, paranasal sinus, and orbital cavity. He received radiotherapy to which he had complete responses. After 2 years, he visited our hospital because of a month-long headache. He was diagnosed with EMP recurrence in the CNS via brain magnetic resonance imaging and cerebrospinal fluid analysis. He was treated with whole brain radiotherapy and intrathecal chemotherapy with methotrexate, but he expired due to pneumonia.

To increase the efficiency of a two-stage anaerobic wastewater digestion system, various polymers were added to the methanogenic reactor as supports. The addition of polyurethane addition (6%, w/v) to the methanogenic reactor facilitated the organic loading rate (2-day Hydraulic Retention Time), higher than that of the conventional methanogenic reactor (6-day HRT). During the operation of the polyurethane-added reactor, a significant decrease in the organic mass in the effluent (COD 5-6 kg/l) was achieved, compared to that of the conventional reactor (COD 15-20 kg/l). The methane gas production rate also improved about 3-fold in the polyurethane-added reactor. More biomass was found to accumulate in the polyurethane-liquid phase (volatile solid, 26-28kg) than in the free-liquid phase (volatile solid, 5- 7 kg/l) after 90 days of operation. A scaled-up experiment with a polyurethane-added 2.5-1 reactor confirmed the previous results, and no adverse effects such as plugging or channeling due to decreased efficiency was observed even after 4 months of operation.

To reduce tobacco use and related harm in Korea, telephone based cessation services (Quitlines) began full operation to provide regular behavioral counseling for smoking cessation in 2006. After registration in the cessation program, at least 21 calls per year are given to each client to help quit and encourage maintenance. Tailored programs for males, females, and adolescent smokers have been offered taking into account smokers' characteristics and smoking behavior. Mailing self-help quit packs and e-mail and SMS services are allowable as additional services.A total of 23,201 smokers were registered on the Quitline program from 2006 to 2014. In 2014, an average of 13,343 calls per month have been received by 28 coaches, the 1 year abstinence rate of clients is 26%, and clients' satisfaction rate is 81.6%. After introduction of the call system in 2007, client convenience and effective operations have been achieved with high technology support of a computer-based telephone system. Systematic education and evaluation programs for quit coaches have contributed to quality assurance of the services. Currently, research into development of new programs and evaluation of Quitline performance is being undertaken. A Comprehensive Multi-channel Cessation Center (CMCC) has been suggested and is now planned as a next step in the national program for smoking cessation.
