OBJECTIVES: Since the report of the first confirmed case in Daegu on February 18, 2020, local transmission of coronavirus disease 2019 (COVID-19) in Korea has continued. In this study, we aimed to identify the pattern of local transmission of COVID-19 using mathematical modeling and predict the epidemic size and the timing of the end of the spread. METHODS: We modeled the COVID-19 outbreak in Korea by applying a mathematical model of transmission that factors in behavioral changes. We used the Korea Centers for Disease Control and Prevention data of daily confirmed cases in the country to estimate the nationwide and Daegu/Gyeongbuk area-specific transmission rates as well as behavioral change parameters using a least-squares method. RESULTS: The number of transmissions per infected patient was estimated to be about 10 times higher in the Daegu/Gyeongbuk area than the average of nationwide. Using these estimated parameters, our models predicts that about 13,800 cases will occur nationwide and 11,400 cases in the Daegu/Gyeongbuk area until mid-June. CONCLUSIONS We mathematically demonstrate that the relatively high per-capita rate of transmission and the low rate of changes in behavior have caused a large-scale transmission of COVID-19 in the Daegu/Gyeongbuk area in Korea. Since the outbreak is expected to continue until May, non-pharmaceutical interventions that can be sustained over the long term are required.

Purpose: This study aimed to measure willingness to use (WTU) and appropriate payable cost of visiting nurse service for the elderly and explore their impact factors. Methods: The study included 752 participants selected from data that were completed in 2017 for the elderly aged over 60 nationwide. Logit and Tobit regression analysis were performed to confirm the influencing factors. Results: The study found that 39.1% of the elderly in the community were WTU the visiting nurse service, and they reported that the cost per visit was 12,650 Korean Won. The factors influencing WTU were having less than moderate subjective health status (OR = 1.63, p = .011), being part of a social participating groups (OR = 1.50, p = .046), or participation in senior health promotion programs (SHPPs) (OR = 1.96, p = .003). The cost was also influenced by less than moderate subjective health status (β = 4.37, p = .021), being part of a social participating groups (β = 4.41, p = .028), or participation in SHPPs (β = 4.87, p = .023). Additionally, elderly people living alone who were used as covariates were highly WTU (OR = 2.20, p = .029). Conclusion This study provides evidence to predict demand for visiting nurse service and reflects consumer value in setting the service cost. This is the first study to derive cost from consumers' perspective regarding the service for the elderly. As it is the result of an open-ended survey, follow-up studies are needed to estimate more reliable and reasonable results.

Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle school. The subjects completed a pre-tested questionnaire. The average monthly frequency of fast food consumption was 4.05 (4.25 for boys, 3.83 for girls). As expected, fast food consumption was considered to be a special event rather than part of an everyday diet, closely associated with meeting friends or celebrating, most likely with friends, special days. The Theory of Planned Behavior effectively explained fast food consumption behaviors with relatively high R2 around 0.6. Multiple regression analyses showed that fast food consumption behavior was significantly related to behavioral intention (b = 0.61, P < 0.001) and perceived behavioral control (b = 0.19, P < 0.001). Further analysis showed that behavioral intention was significantly related to subjective norm (b = 0.15, P < 0.01) and perceived behavioral control (b = 0.56, P < 0.001). Attitude toward fast food consumption was not significantly associated with behavioral intention. Therefore, effective nutrition education programs on fast food consumption should include components to change the subjective norms of fast food consumption, especially among peers, and perceived behavioral control. Further studies should examine effective ways of changing subjective norms and possible alternatives to fast food consumption for students to alter perceived behavioral control.

PURPOSE: The purpose of this study was to analysis the manuscripts rejected for publication in the Journal of Korean Academy of Nursing Administration during the last three years six months (2012~2015 Jun). METHODS: Seventy eight rejected manuscripts were analyzed focusing on manuscripts characteristics, such as rejection rates, year of submission, occupation of first author and corresponding author, number of authors, funding, thesis or dissertation, article type, study participants, number of reviews prior to rejection, and 3rd reviewer. Also reviewers' quantitative evaluation scores and subjective comments were analyzed. Reviewers' subjective comments were analyzed using content analysis methodology. RESULTS: The mean rate for manuscript rejection was 28.9% and for quantitative research, qualitative research, and review papers the quantitative evaluation scores were 2.54+/-0.70, 2.39+/-0.69, and 2.39+/-0.69 out of 5 points, respectively. The most frequent subjective comment on rejected manuscripts was 'lack of rationale for research need'. CONCLUSION: In this study the characteristics and the reasons for rejecting manuscripts were identified. These findings can be used in developing effective strategies for researchers, reviewers and editors to improve the quality of research and research reviews of nursing administration research.
