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.
2.Willingness to Use and Appropriate Payable Cost for Visiting Nurse Service for the Elderly in the Community
Journal of Korean Academy of Nursing 2022;52(1):105-119
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.

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.

Nutrition Research and Practice 2011;5(2):169-178
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.

Objectives:
Previous studies have reported that self-neglect, which may be a sign of elder abuse, can result in suicide among older adults. The signs of self-neglect and its impact on the risk of suicide may differ by gender. Thus, this study explored the association between self-neglect and suicide risk in older Korean adults and examined the potential moderating effect of gender on this relationship.
Methods:
Data were collected from 356 Korean adults aged 65 or older through an online survey. Multiple regression analysis was used to test the research hypothesis. First, the associations between 4 sub-dimensions of self-neglect (i.e., daily life management issues, personal hygiene issues, financial management issues, and relational issues) and suicidal ideation were examined. Then, the moderating effect of gender on these relationships was investigated by including interaction terms.
Results:
Self-neglect was significantly associated with suicidal ideation in older adults. Aspects of self-neglect related to daily life management and relational factors were key predictors of suicidal ideation. Gender significantly moderated the effect of the relational dimension of self-neglect on suicidal ideation. The relational dimension of self-neglect was more strongly associated with suicidal ideation in older women than in older men.
Conclusions
The findings suggest the importance of screening older adults with signs of self-neglect for suicide risk. Special attention should be paid to older women who experience relational issues as a high-risk group for suicidal ideation. Public programs and support systems should be established to improve daily life management and promote social relationships among older adults.
8.Analysis of Trends in Willingness to Pay Research in Healthcare Service of Korea
Journal of Korean Academy of Community Health Nursing 2021;32(1):24-39
Purpose:
This study was to review the previous studies on the ‘Willingness to Pay (WTP)' for healthcare services and suggest future implications for nursing research.
Methods:
Using the scoping review method, we used RISS, KISS, KMbase, Koreamed, PubMed, EMbase, CINAHL as searching engines. According to the selection and exclusion criteria, 40 appropriate studies were selected and analyzed.
Results:
24 studies were categorized into medical service field among medical, public health, and nursing service fields. A total of 16 studies were related to healthcare system (policies), 13 studies were to the healthcare intervention, and 11 studies were categorized into the health management. Most of the methods for eliciting WTP (70%) were about a contingent valuation method (CVM), and the use of double bounded dichotomous choice (DBDC) tended to increase. In the nursing field, five WTP studies were identified: two studies published in the early years of 2000, which were conducted on hospital-based home health visit services. Recent studies were mostly about counseling and education by advanced practice nurses (APNs).
Conclusion
WTP studies on healthcare services were largely published from the medical fields and health policy areas with the CVM method. In the field of nursing, studies have been conducted on the subject of limited service areas. More active exploration of research topics is required, particularly under the current policy setting, where discussion of the public health insurance fee for nursing practice is essential.

The purpose of this retrospective study was to evaluate the survival rate by comparing Class II restoration using flowable resin composite with stainless steel crown in primary molars.
Electronic medical records and radiographs of 1,504 primary molars with proximal caries of 590 patients from June 2015 to August 2019 were analyzed. With the collected data, survival analysis was performed using the Kaplan-Meier method.
The 1-year survival rate of flowable resin composite in the primary molar was 98.5%, 3-year survival rate was 87.7%, and mean survival time was 39 months. There was no statistically significant difference between flowable resin composite and stainless steel crown (p = 0.896).
Within the limits of this study, Class II restoration using flowable resin composite can be considered a promising option for the treatment of proximal caries in primary molars.
