Purpose The purpose of this study is to find effective skin scuba activation factors and to provide basic data that extend the scope of research related to skin scuba. Methods Delphi method was used and the experts were categorized by experts to analyze the results. The questionnaires collected through the 2nd and 3rd delphi surveys were SPSS win ver. 22.0 and Microsoft Office Excel 2013 to calculate mean, standard deviation, median, and coefficient of variation. The concrete conclusions are as follows. Conclusions First, in terms of organization sub-factor, fostering sports-for-all participants and college club came out to be very effective and followed by cooperation system with Ministry of Public Safety and Security and Ministry of Oceans and Fisheries, strengthening cooperation and exchange with other education organizations, initializing new scuba diving education organization management and inspection institution and establishing scuba diving education organization. Second, in terms of facility/equipment sub-factor, factors that cause most effectiveness came out as expanding scuba-diving installation, developing connection system with medical department, enlarging indoor-diving education facilities, improving scuba diving equipment, consecutively. Third, in terms of leader sub-factor, training instructor through leader personality education and verification came out to be the most effective, followed by objectifying professional education institution leader training system, improving leader treatment. Fourth, in terms of program sub-factor, it is found that safety education program as the most effective factor, coming next with environment education/professional manpower training program, developing various programs, lastly, inventing insurance product. Fifth, in terms of advertisement sub-factor, as in order of guiding publics to change their view towards scuba-diving, expanding scuba-diving related events and establishing advertisement system had its effectiveness. Sixth, in terms of policy sub-factor, establishing cooperation system among administration departments came out to be most effective and then improving related law-system.
To provide the distribution of cardiorespiratory fitness including Bruce treadmill exercise time and estimated peak oxygen uptake (VO2peak) and investigate association with cardiorespiratory fitness and metabolic syndrome, sedentary lifestyle, or education level among Korean adults. Analysis of data on 2,006 adults (19-64 yr) who had completed a maximal grade treadmill exercise test, from the Sports Institute of Sports Science Fitness Standards (KISS FitS) project 2014-2015. The mean maximal exercise time was 11’26’‘, 11’18’‘, 11’06’‘, 10’03’‘ and 8’51’‘ (minutes and seconds) for men 19-29, 30-39, 40-49, 50-59 and 60-64 years of age, respectively, for women, it was 9’49’‘, 9’09’‘, 8’42’‘, 8’01’‘ and 7’33’‘ for the corresponding age groups. The mean peak oxygen uptake was estimated as 42.3, 41.8, 41.2, 37.6 and 33.6 ml/kg/minute for men 19-29, 30-39, 40-49, 50-59 and 60-64 years of age, respectively, For women, it was 34.0, 31.8, 30.3, 28.0 and 26.4 ml/kg/minute for the corresponding age groups. A positive association between cardiorespiratory fitness level and education level was observed for both men and women. Furthermore, participants with sedentary lifestyle had a significantly lower cardiorespiratory fitness than participants with activity lifestyle. Finally, Men with moderate and high fitness level had 50% and 87% lower odds for the metabolic syndrome, and women had 48% and 50% lower odds for the metabolic syndrome, respectively, than the ones with low fitness level after adjustment for age, smoking, alcohol intake, and sedentary lifestyle. These results can be used to track future Korean assessments and to evaluated interventions. The differences in fitness status by education level, sedentary lifestyle or metabolic syndrome can also be used to develop health policies, program and educational services.
The purpose of this study which is follow up study of Lee and Kim(2015b)'s was to analyse error sources and estimation of reliability in peer review of forced connection method-sportscasting by applying generalizability theory. Generalizability theory quantify error sources of the data measured under certain specific situation set by the researchers. It is an analysis method that the relative influences of each error sources taking from score is determined(G-study), and the effective measurement condition future applicable is provided(D-study). Participants were 10th high school students(N=216). Data were collected from student's peer review results and analyzed using univariate and multivariate generalizability theory. Results showed that error source for video have a more significant impact than other error sources. But the result by analyzing the gender difference was that error source for the interaction of video and participants have a more significant impact than other error source in the case of girls. Peer review used in this study showed high generalizability coefficient and even when reducing the number of video or participants it can maintain the adequate reliability. But generalizability coefficient of boys was higher than girls and specific measurement conditions leading to enhanced reliability were different when analyzing by gender difference. Also, method of analysis which cannot reflect measurement conditions properly estimates the reliability excessive. Discussions were provided in term of the relative influences of each error sources, the effective measurement condition maintaining the Generalizability coefficient of a certain level, and the comparison the Generalizability coefficient with the way of estimation traditional reliability applying univariate and multivariate Generalizability theory taking from score in peer review of forced connection method-sportscasting.
