Purpose: This study aimed to develop and evaluate an integrated management program to enhance self-efficacy, compliance with sick-role behaviors, symptom management, and biomarker indication in hemodialysis patients. Methods: The integrated management program was developed through a systematic review of literature, analysis of relevant online data, and expert validation. It comprised 480 min of video-based education delivered eight times over four weeks, supplemented by weekly phone consultations and text message support from a nurse. To evaluate the program's effectiveness, it was administered to 44 patients with hemodialysis in a single group in a pre-post test experimental study. Changes in self-efficacy, sick-role behavior compliance, dialysis symptom index, and biomarkers were assessed. Results: The program yielded statistically significant improvements in self-efficacy (t=-7.13, p<.001), sick-role behavioral compliance (t=-7.35, p<.001), dialysis symptom index (t=4.32, p<.001), and blood urea nitrogen levels (t=2.55, p=.014) among the participants. Conclusion: The integrated management program is an effective intervention for improving hemodialysis patients' self-efficacy, compliance with sick-role behaviors, and experience of symptoms. Additionally, it is considered an intervention with high clinical applicability and efficiency through video reproducibility.

BACKGROUND/OBJECTIVES: Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. SUBJECTS/METHODS: A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. RESULTS: Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. CONCLUSIONS: Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

The association of menarche and nutritional status was studied in 116 female students of the 6 th grade in a rural primary school. Participants were divided into two groups based on menarcheal status. The anthropometric data showed that mean heights and weights of menarcheal group on two occasions were significantly higher than those of the other group (p<0.01). Neither hemoglobin levels nor hematocrit values for determination of anemia were not associated with menarche. Twenty four hour dietary recall revealed that young females with menarche consumed less energy and Ca compared to the other group. Ca intake was 34.8% of RDA in menarcheal group. It might be suggested that effective intervention strategies need to be developed and include education programs for nutritional needs and food sources of Ca, targeting rural residents.

Oral mucositis or stomatitis produced by stomatotoxic chemotherapy and/or radiation therapy are painful, restrict oral intake and, importantly, act as sites of secondary infection and potals of entry for the endogenous oral microflora often leading to bacteremias or sepsis. A number of clinical observations and studies of animal model suggests a pathophysiological complexity in the development of mucositis. The condition appears to represent a sequential interaction of the oral mucosal cells and tissues, pro-inflammatory cytokines, and local environmental factors in the mouth. This article discussed and reviewed biological process of the mucositis and, the role of cytokines as initiators and amplifiers of the process. The recognition that the pathophysiology of mucositis is a multifactorial process has presented opportunities for intervention based upon biological attenuation.

In cognitive radios, spectrum sensing plays an important role in accurately detecting the presence or absence of a licensed user. However, the intervention of malicious users (MUs) degrades the performance of spectrum sensing. Such users manipulate the local results and send falsified data to the data fusion center; this process is called spectrum sensing data falsification (SSDF). Thus, MUs degrade the spectrum sensing performance and increase uncertainty issues. In this paper, we propose a method based on the Hausdorff distance and a similarity measure matrix to measure the difference between the normal user evidence and the malicious user evidence. In addition, we use the Dempster-Shafer theory to combine the sets of evidence from each normal user evidence. We compare the proposed method with the k-means and Jaccard distance methods for malicious user detection. Simulation results show that the proposed method is effective against an SSDF attack.

In Korea, diabetes mellitus, which causes micro and macrovascular complications, has been rapidly increasing during recent decades and has become a leading cause of disability-adjusted life years. The prevalence of diabetes mellitus was 12.4% in 2011 and that of prediabetes, a condition of high risk for developing diabetes mellitus, is 1.5- to 3-fold greater than that of diabetes. The diabetes prevention programs in other countries were shown to reduce or delay progression from prediabetes to diabetes mellitus. However, these results are not applicable to Korean people because of genetic and environmental differences. Therefore, we need to plan and perform a diabetes prevention study in Korean. Based on these results, we should design intervention tools for a Korean diabetes prevention program. We can consider several preventive interventions with lifestyle modification suitable for Korean people and pharmacologic treatments such as metformin or alpha-glucosidase inhibitor.

Purpose: The purpose of this study was to examine the relationship between sleep duration, quality of sleep and depression, and to identify the factors associated with depression in middle school students. Methods: This study used a cross-sectional design with secondary data, middle school student panel data from the Korean Children and Youth Panel Survey (2018), and data from a total of 2,590 students was used for analysis. For the statistical analysis, t-test, ANOVA, and hierarchical multiple regression were performed using SPSS ver. 26. Results: The mean depression score in adolescents was 17.99±6.38. Depression had significant differences according to sleep duration and quality. Adolescents with less than eight hours of sleep showed the highest depression, and poor sleepers showed higher depression scores than good sleepers. Gender, school achievement, school satisfaction, economic status, and exercise time were found to significantly relate to depression. After controlling for general characteristics, depression explained 17.2% of the variance in quality of sleep (β=-.15, p<.001) and sleep duration (β=-.04, p=.022). Conclusion: These findings indicate that it is necessary to develop intervention strategies to enhance the quality of sleep and appropriate sleep duration for preventing depression in adolescents.

Purpose: The study aimed to investigate the factors associated with long hours of smartphone usage and to identify the characteristics of the high-risk group among female middle school students in South Korea. Methods: The study analyzed the data of 13,648 female middle school students using their own smartphone extracted from the 13th Youth Health Behavior Online Survey (2017). The factors related to using smartphones for a long time was analyzed by binomial logistic regression. The characteristics of the high-risk group was defined by a decision tree analysis. Results: The average hours spent on smartphone usage was 269.54 minutes per day. The significant factors associated with the long hours of smartphone usage were grade, living with parents, perceived household economic status, perceived academic achievement, stress, sadness and hopelessness, the main purpose of smartphone usage, drinking, body mass index, breakfast, and satisfaction with sleep quality. The subjects showing low academic performance and having breakfast four times a week or less were more likely to use their smartphone for a long time. Conclusion: Based on the results of the research, we need to establish intervention strategies focusing on the factors influencing long-time usage of smartphone. Particularly, the subjects who show poor academic performance and skip breakfast frequently should be considered as the high-risk group for spending long hours on smartphone usage.

Objectives: Community-Based Participatory Research (CBPR) is a kind of health promotion approach to increase social cohesion and sense of community, which has built the collaborated partnership in all phases. This has the co-ownership of research objectives and knowledges produced by residents, and the outcome was taken to enhance community empowerment. This study performed to embody CBPR, which had regulated collective health status approached by social epidemiology. Methods: Reference review had been exercised focused on CBPR books and papers published since 1990. Our interests were aimed at its paradigm and methodological issues. Particularly, we problematized its feasibility in the social and behavioral foundations of pubic health. Results: According to the review, CBPR shared critical understanding and decision-making related to their community development including health status. Therefore, it was strength-based approach in spite of scientific dichotomy. CBPR created social cohesion and community empowerment with all participants, because it sublated contradiction between subjectivism and objectivism. Conclusions: The success of CBPR needs what we so called trust, democracy, collaboration, devotion, and consensus of equity. Despite these factors, CBPR may be a methodological transition to prepare some intervention of health inequality. This is because it does emphasize a mixture of theory and praxis to manage vulnerable people in community.
