In Korea, 'spoon class discourse' has attracted public attention in the press and among young people, which reflects that mass awareness that the class status structure is clearly rooted in the society becomes widespread. Although income distribution has been improved since late 2000s, it is interesting that Korean people's subjective perception concerning class mobility and social justice has been worsemed. By using the survey data on people's perception of opportunity inequality, this study finds that Korean people have by and large negative subjective awareness regarding socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts, and that the degree of the negative perception is greater in accordance with the people's subjective identification. The regression analysis reveals that the social status of respondents and their parents(-), experience of discrimination(+), age(-), and high education of college and above (+) have consistent effect over socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts with statistical significance. More concretely, as people have lower subjective status identification at the time of parent generation and their own generation, as they have the experience of discriminatory misconduct, and as they are young and highly educated, they have negative or pessimistic perception regarding opportuinity inequality. In addition, it is revealed that the unemployed and non-regular workers have significantly negative perception on socio-economic opportunity inequality, magnitude of opportunity inequality, while negative perception on the magnitude of opportunity inequality and achievement by efforts is noticeable among high and middle income households.

This exploratory study, related to the introduction of Western-style family doctors, was conducted based on a comparative survey of medical care satisfaction in foreign residents of the U.S. and Canada based on a consumer-centered perspective. As a result of statistical analysis based on 493 collections of empirical data from 2016 to 2018, the main conclusions of this study are as follows. First, there was no evidence that satisfaction with US and Canadian family doctors was higher than the satisfaction with Korean primary care physicians. Second, satisfaction with Korean primary care physicians was high with regard to treatment, promptness, etc., and there was no evidence that foreign family doctor systems were better in terms of sufficient counseling and explanation. Third, overseas Koreans in the United States showed less satisfaction with their family doctors than Koreans in Canada. Fourth, overseas Koreans preferred to visit a hospital directly, without a referral from the family doctor. In conclusion, there is insufficient evidence showing that satisfaction with family doctors in the U.S. and Canada is higher than satisfaction with primary care doctors in Korea. Therefore, a more in-depth, additional analysis on the Western-style family doctor is needed before introducing such a system in Korea.

Background: Postoperative analgesia (POA) is an important determinant of successful treatment. Dexmedetomidine (DEX) has recently gained attention as a promising adjuvant to local anesthetics (LA). The present study aimed to evaluate the efficacy and safety of levobupivacaine (LB) as an adjuvant during inferior alveolar nerve block (IANB) in the extraction of lower impacted third molars (LITM). Methods: A prospective, randomized, placebo-controlled, triple-blind, parallel-arm, and clinical study was performed on 50 systemically healthy participants who required removal of an asymptomatic LITM. Using a 1:1 distribution, the participants were randomized into two groups (n = 25). Group L (control group) received 1.8 mL of 0.5% LB and 0.2 mL normal saline (placebo) and Group D (study group) received a blend of 1.8 mL of 0.5% LB and 0.2 mL (20 ㎍) DEX. The primary outcome variable was the duration of POA and hemodynamic stability, and the secondary variable was the total number of analgesics required postoperatively for up to 72 h. The participants were requested to record the time of rescue analgesic use and the total number of rescue analgesics taken. The area under the curve was plotted for the total number of analgesics administered. The pain was evaluated using the visual analog scale. Data analysis was performed using paired students and unpaired t-test, Mann-Whitney U test, Chi-square test, and receiver operating characteristic analysis. Statistical significance was set at P < 0.05. Results: The latency, profoundness of anesthesia, and duration of POA were statistically significant (P < 0.05). The differences between mean pain scores at 6, 12, 24, 48, and 72 h were found to be significant (each P = 0.0001). Fewer analgesics were required by participants in group D (2.12 ± 0.33) than in L (4.04 ± 0.67), with a significant difference (P = 0.0001). Conclusion: Perineurally administered LA with DEX is a safe, effective, and therapeutic approach for improving latency, providing profound POA, and reducing the need for postoperative analgesia.

Purpose. The aim of this study is to evaluate bone change around the implant in patients who underwent alveolar ridge preservation for implantation in the posterior teeth using radiographic data measuring changes of mesial, distal crestal bone level according to post-implantation, post-final prosthesis delivery and follow-up periods. Materials and methods. In total, 36 implants were placed in 32 patients. The mesial and distal crestal bone level of all the areas where alveolar ridge preservation was performed uses panoramic images taken post-implantation, post-final prosthesis delivery, and follow-up period each was measured and evaluated as a vertical value. The following factors were analyzed: associations between changes of crestal bone level and factors (e.g., age, sex, systemic diseases, dentist, implant location, tooth, bone type, membrane). The statistical analysis was performed using the mean, standard deviation and independent t-test, paired t-test (P < .05). Results. Analysis of crestal bone level differences between periods shows statistically significant differences (P < .05). There was no statistically significant difference when the changes of crestal bone level between post-implantation, post-final prosthesis delivery and follow-up periods were correlated with each factors. Conclusion. After alveolar ridge preservation, bone around the implant remained stable during the maintenance period without being affected by the patient and surgical factors, and alveolar ridge preservation is considered a clinically usable procedure.

In the era of low growth, many provincial cities are experiencing population decline and aging. Population decline phenomena such as reduction of productive manpower, reduction of finances, deterioration of quality of life, and collapse of the community base are occurring in a chain and are being pushed to the brink of extinction of the cities. This study aims to propose a methodology to objectively estimate the employment creation centers and setting the basic unit of industrial-centered zoning by applying spatial statistical techniques and GIS for the application of the compact city plan as an efficient spatial management policy in a city with a declining population. In details, based on reviewing previous studies on compact city, 'employment complex index(ECI)' were defined considering the number of workers, the number of settlers, and the area of development land, the employment creation center was estimated by applying the 'Local Moran's I' and 'Getis-Ord's Hot-Spot Analysis'. As a case study, changes in the four years of 2013, 2015, 2017, and 2019 were compared and analyzed for Changwon City. As a result, it was confirmed that the employment creation center is becoming compacted and polycentric, which is a significant result that reflects the actual situation well. This results provide the basic data for functional and institutional territorial governance for the regional revitalization platform, and provide meaningful information necessary for spatial policy decision-making, such as population reduction, regional gross domestic product, and public facility arrangement that can respond to energy savings, transportation plans, and medical and health plans.
