  • The purpose of this research is to develop basic materials useful for the visiting management policies' establishment of national parks by analyzing the characteristics of and satisfaction with the visit to Hallyeohaesang National Park according to travel routes. For this, a total of 671 visitors to Hallyeohaesang National Park were recruited and field surveys were conducted three times in spring, summer, and fall from March to November 2017. The Hallyeohaesang national park's visitors were surveyed using a self-administered questionnaire about visitor characteristics (ex: motivation of visiting, travel routes, travel time, and participating activities, etc.) and satisfaction (ex: satisfaction with the visit, intention to revisit, and intention to recommend). SPSS 21.0 program was used for the statistical analysis: frequency analysis and independent-samples t-test analysis. As a result of analysis the motivation of visiting, those who visited only Hallyeohaesang National Park (a single destination) showed a mean value statistically significantly higher level in health improvement and vacation, relaxation, and healing compared to those who had visited or would visit other places along with Hallyeohaesang National Park (multi-destinations). Single destination visitors spent less time traveling from home to national park than multi-destinations visitors. Those who visited only Hallyeohaesang National Park (as a single destination) showed a mean value statistically higher satisfaction and intention to revisit and recommend. The results of this research have significance in providing basic materials to develop efficient park management policies by studying the characteristics of Hallyeohaesang National Park visitors.

  • Objectives: The water fluoridation program has been implemented since 2008, in a region of Geoje City. This study aimed to evaluate the effectiveness of the water fluoridation program on caries prevention in the permanent dentition. Methods: Evaluation surveys were conducted on 8-, 10- and 12-year-old children in the fluoridated and non-fluoridated regions of Geoje City, in 2015. The survey included 834 children from the fluoridated regions and 703 from the non-fluoridated regions. The data obtained from the survey were analyzed using the IBM SPSS statistical package version 23.0. The effectiveness of community water fluoridation in caries prevention was estimated by the differences in the decayed, missing, filled teeth (DMFT) and decayed, missing, filled surfaces (DMFS) scores, between the program and control groups. The mean numbers of fissure-sealed teeth and surfaces were adjusted to reduce their confounding effect. Results: The mean DMFT and DMFS scores (0.69 and 0.91, respectively) of 10-year-olds from the fluoridated regions, after adjusting for the numbers of fissure-sealed teeth and surfaces, were significantly lower than those of the 10 year olds (DMFT: 0.95, DMFS: 1.32) from the non-fluoridated regions. The effectiveness of water fluoridation on caries prevention in the permanent dentition, estimated based on the differences in the mean DMFT and DMFS scores, adjusted for the number of fissure-sealed teeth and surfaces, between the program and control groups of 10-year-old children, was 27.4% and 31.1%, respectively. Conclusions: These results suggest that the effectiveness of water fluoridation on caries prevention in the permanent dentition, in Geoje City was so high that this program should be implemented in other regions in Korea as well.

  • This research has been focused on accessing precision and accuracy of UAV (Unmanned Aerial Vehicle)-derived 3-D surveying coordinates. To this end, a highly precise and accurate testing control network had been established by GNSS (Global Navigation Satellite Systems) campaign and its network adjustment. The coordinates of the ground control points and the check points were estimated within 1cm accuracy for 95% of the confidence level. FC330 camera mounted on DJI Phantom 4 repeatedly took aerial photos of an experimental area seven times, and then processed them by two widely used software packages. To evaluate the precision and accuracy of the aerial surveys, 3-D coordinates of the ten check points which automatically extracted by software were compared with GNSS solutions. For the 95% confidence level, the standard deviation of two software's result is within 1cm, 2cm, and 4cm for the north-south, east-west, and height direction, and RMSE (Root Mean Square Error) is within 9cm and 8cm for the horizontal, vertical component, respectively. The interest is that the standard deviation is much smaller than RMSE. The F-ratio test was performed to confirm the statistical difference between the two software processing results. For the standard deviation and RMSE of most positional components, exception of RMSE of the height, the null hypothesis of the one-tailed tests was rejected. It indicates that the result of UAV photogrammetry can be different statistically based on the processing software.

  • Artificial intelligence, which is developing as the core of an intelligent information society, is bringing convenience and positive life changes to humans. However, with the development of artificial intelligence, human rights and property are threatened, and ethical problems are increasing, so alternatives are needed accordingly. In this study, the most controversial artificial intelligence ethics problem in the dysfunction of artificial intelligence was aimed at researching and developing artificial intelligence ethical measurement indicators to protect human personality rights and property first under artificial intelligence ethical principles and components. In order to research and develop artificial intelligence ethics measurement indicators, various related literature, focus group interview(FGI), and Delphi surveys were conducted to derive 43 items of ethics measurement indicators. By survey and statistical analysis, 40 items of artificial intelligence ethics measurement indicators were confirmed and proposed through descriptive statistics analysis, reliability analysis, and correlation analysis for ethical measurement indicators. The proposed artificial intelligence ethics measurement indicators can be used for artificial intelligence design, development, education, authentication, operation, and standardization, and can contribute to the development of safe and reliable artificial intelligence.

  • The purpose of this study is to develop a teaching and learning plan for parental understanding classes for middle school students and to investigate the effect of the classes on the parent-child relationship by implementing the class. The classes were conducted from July 5 to July 15, 2021, for the second graders of S middle school in Gwangju Metropolitan City, in a total of 6 sessions, i.e., 3 sessions per week for 2 weeks. The influence of classes on parent-child relationship was measured in terms of the understanding of the middle age, degrees of interaction, affection, and bond with parents. In order to analyze the impact of classes, pre- and post-class online surveys were conducted on 184 students who agreed to participate. For the collected quantitative data, descriptive statistics, reliability analysis, and pairwise t-tests were performed using the SPSS Ver 22.0 statistical program. According to the results, students' understanding of the developmental characteristics of middle age increased and the interaction between the students and their parents increased after the class. And the overall affection with the mother increased significantly. Also, students' bonds with both mother and father were significantly improved. Based on these results, the necessity and direction of home economics class were discussed to form a positive relationship between adolescent children and their parents.

  • Purpose: This study was conducted to understand the public awareness of landslide and check dams in 2015-2020 using the big data platform 'Hyean' and to confirm the utilization of this platform in disaster prevention areas. Method: The total amount, number of detection by period by media, and affirmative and negative trends of a search for 'landslide' and 'check dam' in 2015-2020 were analyzed using a keyword search of 'Hyean.' Result: There is significant lack of public awareness of check dam compared to landslide, and the trend is more noticeable in the conspicuous gap of data amount between the news and SNS media. The number and the timing of the search for 'landslide' coincided with the actual occurrence of landslide, while the detection of 'check dam' was less related to it. Relatively affirmative preception for the check dam is inferred, but it was difficult to confirm accurate statistical affirmative and negative trends in the disaster prevention field using 'Hyean.' Conclusion: Unlike the experts who expect positive public awareness of check dam, the statistic results show that the public awareness of the check dam as an effective countermeasure against landslide was extremely low. Active promotion of erosion control projects should be carried out first, and a balanced sample survey should accompany online and periodic field surveys. Since there is a limit to grasping the effective perception in the field of disaster prevention area using 'Hyean', it should be very cautious to establish local/governmental policies using it.

  • This study aimed to determine foodservice and hygiene management statuses at welfare facilities catering to disabled persons by facility type to provide basic data for foodservice management guidelines. An online survey was distributed to workers at 1,984 welfare facilities for disabled persons in Korea, and 531 facilities responded, which represented a response rate of 26.8%. The survey requested general information about the facilities, facility users, meals, hygiene, and management. Statistical analyses were performed, and frequency analysis and the chi-square test were used to investigate responses by facility type. The survey results revealed that daycare centers were most common and accounted for 27.4% of responses. Residential facilities for the severely disabled and sheltered workshops accounted for 16.9% and 16.4%, respectively, and residential facilities by disability type accounted for 13.0%. The presence of dietitians at welfare facilities varied by facility type. Welfare centers for the disabled (94.7%) had the highest percentage of dietitians, followed by residential facilities for the severely disabled (87.8%). On the other hand, sheltered workshops and daycare centers for disabled persons had the lowest percentages of dietitians (10.3% and 4.1%, respectively). This study highlights the variations that exist in foodservice management across different welfare facilities for disabled persons and emphasizes the challenges faced by those responsible for managing foodservices and maintaining hygiene, particularly in large facilities with no dietitians. Therefore, we recommend tailored meal management guidelines be developed for each type of welfare facility for disabled persons.

  • The purpose of this study is to examine the effects of emotional labor on job stress and the professional identity of sports coaches for people with disability. 190 surveys targeting sports coaches for people with disability working at sports associations for people with disability, rehabilitation sports centers, and welfare centers for people with disability in the metropolitan area were collected and used for analysis. Using the SPSS 22.0 statistical program, the collected data were subjected to frequency analysis, correlation analysis, and multiple regression analysis. As a result of the study, it was confirmed that emotional dissonance, a sub-factor of emotional labor, affects role ambiguity and role overload in job stress. The expression diversity, a sub-factor of emotional labor, had an impact on publicity, use of professional organizations, and sense of responsibility, which were sub-factors of professional identity. It was confirmed that emotional dissonance affects the autonomy of professional identity and the sense of responsibility. It was also confirmed that role ambiguity, a sub-factor of job stress, had an effect on professional identity, and that role overload had an effect on publicity and autonomy. As a follow-up, a detailed in-depth study including perceptions and thoughts on the types of emotional labor of sports coaches for people with disability according to national regions and categories other than metropolitan areas is needed.
