Objective: The outbreak of Middle East Respiratory Syndrome (MERS) started in South Korea in May 2015 and the end of crisis was declared in December 2015 by Korea Centers of Disease Control and Prevention (KCDC). However, Zika virus emerged in less than 2 months following MERS and showed higher mortality than other countries. This study is to assess the current prevention system of overseas infectious diseases, based on MERS and Zika virus outbreak and to suggest effective response system for the future. Methods: We conducted two surveys on medical specialists working at tertiary general hospitals regarding the effectiveness of responding system by KCDC against MERS and Zika virus and education in individual medical institutions using 5-Likert points. Response system was examined in three different periods as initial period, spreading period, and post disease period. Results: Although medical specialists received the notifications in initial period, no practical prevention was proven to be placed in responding stage by medical facilities (averagely 3.5/5 points in total and sub-analyses). During spreading period, there were several academic seminars conducted, which were evaluated as helpful. In post disease period, all answered that there were changes on patient treatment in all medical facilities, with mainly report system and the treatment regulations in case of suspicious patients for infection. Only 49% respondents answered positive on the possibility of initial responses. For questionnaire items regarding Zika virus, all answered that there were notifications prior to the first outbreak of the infected patient. Eighty% of respondents were aware of 'the Guideline system for traveling to dangerous areas', and answered that the system was moderately effective (averagely 3.8/5 points in total). For the effectiveness of prevention measures for foreign novel disease by KCDC, the average point was 3.0 in both of total and sub-analyses. Conclusion: There is not enough response system to prevent infectious disease in medical institutional and governmental levels in Korea. It would warrant the modification of overall medical system to improve preventive measures for initial spread of such diseases.

For the young period, privacy is a crucial factor in establishing one's own identities, values and relationships. The capacity of residential environment to protect individual's privacy takes considerable part in influencing psychological and physiological development of adolescents. This study analyzed adolescents residential values and the elements of spatial plans for the passage and outdoor in Apartment Design Competition of Suwon A district in 2008. One hundred and ten middle and high school students living in Metropolitan area were selected and questionnaire was conducted during February 7 to February 15 in 2009. The data was analyzed by SPSS 11.0 program using one-way ANOVA and crosstab. The study results were summarized as follows; First, the adolescents valued 'safety' the most, regardless of their age and gender and the safety of adolescents commuting should be considered. Second, protecting their own private territories was next important element among other elements. Privacy can be protected by using movable walls, changing the doorway, dividing parents' and adolescents independent territory. Third, in terms of convenience, choosing location of children's room and walking way should be considered. Forth, from the survey, demand for indoors leisure activity was highly valued and required for aesthetic point of view. Considering the sculptures and facilities must satisfy the aesthetics and practicality. Fifth, in terms of social needs, 61.6% of people answered positively to the community facilities for social relationship. Residential environment affects enormous part of adolescents emotional and academic development. Therefore, designing residential areas for adolescents friendly should reflect the demands for safety, territory, convenience, aesthetic and social life.

The effort identifying positioning information of the moving object in real time has been a issue not only in sport biomechanics but also other academic areas. In order to solve this issue, this study tried to track the movement of a pitched ball that might provide an easier prediction because of a clear focus and simple movement of the object. Machine learning has been leading the research of extracting information from continuous images such as object tracking. Though the rule-based methods in artificial intelligence prevailed for decades, it has evolved into the methods of statistical approach that finds the maximum a posterior location in the image. The development of machine learning, accompanied by the development of recording technology and computational power of computer, made it possible to extract the trajectory of pitched baseball from recorded images. We present a method of baseball tracking, based on object tracking methods in machine learning. We introduce three state-of-the-art researches regarding the object tracking and show how we can combine these researches to yield a novel engine that finds trajectory from continuous pitching images. The first research is about mean shift method which finds the mode of a supposed continuous distribution from a set of data. The second research is about the research that explains how we can find the mode and object region effectively when we are given the previous image's location of object and the region. The third is about the research of representing data into features that we can deal with. From those features, we can establish a distribution to generate a set of data for mean shift. In this paper, we combine three works to track baseball's location in the continuous image frames. From the information of locations from two sets of images, we can reconstruct the real 3-D trajectory of pitched ball. We show how this works in real pitching images.

Objectives: A systematic review and a meta-analysis were performed investigate the factors related to turnover intention of dental hygienists in Korea. Methods: Literature between 2000 and January 2021 were used to support the meta-analysis, which focused on 21 factors extracted from 50 articles using a random effects model. The correlation coefficient, r, in the effect size was calculated. Results: Substantial literature was published after 2011 (76%); in academic journals (74%); and targeted nonmetropolitan areas (40%). Lawler's turnover intention tool was used in several studies. The effect size for each ecosystem was in the order of microsystem (r=0.325), mesosystem (r=0.307), macrosystem (r=0.259), exosystem (r=0.176), and individuals (r=0.171). The random-effects model indicated an overall average of r=0.311. The factor that showed a large effect size in relation to turnover intention was organizational commitment of the microsystem (r=-0.594). Furthermore, mesosystem reward (r=- 0.416), microsystem burnout (r=0.464), job stress (r=0.408), and job satisfaction (r=-0.405) were identified as other major factors. Conclusions: To lower the turnover rate of dental hygienists, it is important to focus on factors belonging to the microsystem, and mesosystem reward.

Purpose: This study aimed to derive clues for the franchise industry to overcome difficulties such as various legal regulations and social responsibility demands and to continuously develop by analyzing the research trends related to franchises published in Korea. Research design, data and methodology: As a result of searching for 'franchise' in ScienceON, abstracts were collected from papers published in domestic academic journals from 1994 to June 2021. Keywords were extracted from the abstracts of 1,110 valid papers, and after preprocessing, keyword analysis, TF-IDF analysis, and topic modeling using LDA algorithm, along with trend analysis of the top 20 words in TF-IDF by year group was carried out using the R-package. Results: As a result of keyword analysis, it was found that businesses and brands were the subjects of research related to franchises, and interest in service and satisfaction was considerable, and food and coffee were prominently studied as industries. As a result of TF-IDF calculation, it was found that brand, satisfaction, franchisor, and coffee were ranked at the top. As a result of LDA-based topic modeling, a total of 12 topics including "growth strategy" were derived and visualized with LDAvis. On the other hand, the areas of Topic 1 (growth strategy) and Topic 9 (organizational culture), Topic 4 (consumption experience) and Topic 6 (contribution and loyalty), Topic 7 (brand image) and Topic 10 (commercial area) overlap significantly. Finally, the trend analysis results for the top 20 keywords with high TF-IDF showed that 10 keywords such as quality, brand, food, and trust would be more utilized overall. Conclusions: Through the results of this study, the direction of interest in the franchise industry was confirmed, and it was found that it was necessary to find a clue for continuous growth through research in more diverse fields. And it was also considered an important finding to suggest a technique that can supplement the problems of topic trend analysis. Therefore, the results of this study show that researchers will gain significant insights from the perspectives related to the selection of research topics, and practitioners from the perspectives related to future franchise changes.
