PURPOSE. The purposes of this study were to evaluate the staining resistance of CAD/CAM resin-ceramics polished with different techniques and to determine the effectiveness of the polishing techniques on resin-ceramics, comparing it with that of a glazed glass-ceramic. MATERIALS AND METHODS. Four different CAD/CAM ceramics (feldspathic ceramic: C-CEREC Blocs, (SIRONA) and three resin-ceramics: L-Lava Ultimate, (3M ESPE), E-Enamic, (VITA) and CS-CeraSmart, (GC)) and one light cure composite resin: ME-Clearfil Majesty Esthetic (Kuraray) were used. Only C samples were glazed (gl). Other restorations were divided into four groups according to the polishing technique: nonpolished control group (c), a group polished with light cure liquid polish (Biscover LV BISCO) (bb), a group polished with ceramic polishing kit (Diapol, EVE) (cd), and a group polished with composite polishing kit (Clearfil Twist Dia, Kuraray) (kc). Glazed C samples and the polished samples were further divided into four subgroups and immersed into different solutions: distilled water, tea, coffee, and fermented black carrot juice. Eight samples ($8{\times}8{\times}1mm$) were prepared for each subgroup. According to CIELab system, four color measurements were made: before immersion, immersion after 1 day, after 1 week, and after 1 month. Data were analyzed with repeated measures of ANOVA (${\alpha}=.05$). RESULTS. The highest staining resistance was found in gl samples. There was no difference among gl, kc and cd (P>.05). Staining resistance of gl was significantly higher than that of bb (P<.05). Staining resistances of E and CS were significantly higher than those of L and ME (P<.05). CONCLUSION. Ceramic and composite polishing kits can be used for resin ceramics as a counterpart of glazing procedure used for full ceramic materials. Liquid polish has limited indications for resin ceramics.

The purpose of this study was to examine the differences in the direct medical expenditure of community residents according to their physical activity level. The quota sampling method was used to select samples from a youth community center, senior center, community cultural center, and community recreational sports center in G city in Gyeongbuk-do. Of the 773 questionnaires distributed, 716 were completed. The questionnaires consisted of the demographic characteristics, regular exercise and physical activity levels, health status and medical costs. While the beneficial effect of regular exercise and physical activity on dental costs was not (significant), its effect on the costs of visiting hospital services was (significant). The mean differences in the total monthly direct medical expenditures on outpatient services and medicine for those with very high, high, moderate, low, and very low levels of physical activity were 7,500, 26,299, 47,517, 9,314, and 9,9978 won, respectively. The result of this study supported the findings of previous studies that regular exercise and physical activity. are not associated with the reduction of medical expenditure.

This study aimed to seek the way of effectively managing job stress of shift work nurses, to improve nursing performance, the influence of job stress of shift work nurses on nursing performance through convergence research. A total of 244 questionnaires obtained by a survey targeting nurses, who were doing shift work in a university hospital located in B city, in the period from March 2 to 15, 2015 were analyzed using the SPSS 21.0 program. As a result, the mean score of job stress was 3.57 points, and the mean score of nursing performance was 3.69 points. Job stress made a significant positive(+) influence on the sub-dimensions of interpersonal duty. Therefore, efforts should be made to more accurately identify shift work nurses' job stress and efficiently manage the nursing personnel. Moreover, if shift work nurses' job stress is effectively managed by preparing practical job stress management intervention programs for continuous improvement of nursing performance, high quality medical services will be provided through high quality nursing practice.

In this study, the convergent relation between perception of patient safety culture and safety nursing activity was investigated to prevent safety accidents and prepare data of nursing intervention for patient safety. Nurses in B City who signed on the written consent participated in this study between February 16 and 28, 2015. A total of 266 copies were collected and were analyzed using the SPSS 20.0 program. The mean score of patient safety culture was 3.60 on a scale of 0 to 5, and safety nursing activity, 4.28. The subcategory of perception of patient safety culture, which included the accident report frequency and patient safety level positively (+) influenced safety nursing activity. Therefore, effective communications and report systems in hospitals may be necessary to enhance patient safety culture. Education programs of patient safety should be developed and provided to nurses in hospitals to enhance the levels of patient safety management and their services.

Purpose: The third molar extraction is one of the mostly performed procedures in the department of oral and maxillofacial surgery. In most of dental clinic or hospital, the third molar extraction used to be frequently performed in an office-based surgery, and most patients did not have specific medical history with young ages. Medical history taking are dependent on the only way by asking to the patients about their individual conditions. Therefore, as the specialists of the oral and maxillofacial surgery in the field of dentistry, we suggest a new policy that the preoperative lab must be performed routinely before extraction of the third molar. Methods: This study is based on 1,096 patients who have been managed with third molar extractions, from March 2008 to September 2011 by a single surgeon. The preoperative lab, including complete blood count, coagulation panel, chemistry and serology, was performed before any surgical procedures. The results were informed to the patients regardless of their abnormalities, and any abnormalities related to the surgical procedures, such as platelet count and coagulation factors, were checked and corrected safely. Results: Through the preoperative blood test, systemic diseases that the patients had not recognized before, such as anemia, leukopenia, fatty liver and chronic renal disease, were identified. Patients with acute or chronic leukemia, Hepatitis B, and HIV positive, were also detected as a small number. Also, the possibilities of the cross-infection between dentists and patients or between patients and patients, and any other emergency situations can be prevented; as well as the public health condition can be improved, too. The patients were satisfied with low cost preventive blood test and high quality of medical services. Conclusion: Therefore, routine medical lab testing, including history taking are needed before an office-based minor surgery, such as third molar extractions, and these results were suggested as a new policy in the field of dentistry.

This study used data from the 6rd and 12th year of the Korean Welfare Panel to evaluate the effects of the Personal Assistance Service(PAS) system on the labor market of PAS users' participation. For the purpose of this study, 64 program groups using the Korean PAS and 344 control groups not using the Korean PAS were selected using Caliper matching among the propensity score matching. A chi-square test was used for the difference in characteristics between groups, and a simple difference-in-differences (DID) model and a double-difference multiple regression analysis of DID were performed to estimate the effect of thepolicy before and after the Korean PAS. As a result of the study, it was found that statistically, PAS had no significant effect on the labor market. This is due to the low number of system users, resulting in low post-hoc power, incomplete matching and limited availability of PAS Assistants for Disabled People. Therefore, In order to demonstrate the effectiveness of the Personal Assistance Service(PAS) system, specialized services and systems that meet the needs of the disabled and household members should be implemented.
