BACKGROUND/OBJECTIVES: This study aimed to compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students. SUBJECTS/METHODS: A total of 1,441 elementary, middle, and high school students attending 58 schools in Gyeonggi-do, South Korea participated in the survey in 2015. A questionnaire and informed consent forms for students and legal guardians were sent home and completed responses were returned to the researcher. RESULTS: Approximately 58% of the students perceived the portion sizes of school meals as appropriate and 76.1% consumed almost all or all of the meals served. More elementary and middle school students than high school students consumed almost all or all of the meals (P < 0.001). A regression analysis revealed that the students with a higher dietary behavior score (P < 0.001), higher satisfaction with food service (P < 0.001), a higher environmental protection practice score (P < 0.05), and more positive attitudes toward school meals (P < 0.01) consumed significantly more meals. The provision of foods that taste good and reflecting student opinions on menus were the most important factors for increasing school meal consumption. CONCLUSIONS: To increase consumption of school meals, food service staff should provide students with quality meals and engage students in school food service. Nutrition education that emphasizes healthy eating behaviors and cafeteria environment modification that applies strategies based on behavioral economics can encourage students to consume more school meals.

Technological developments facilitate payment transactions. In 2020, Bank Indonesia issued a regulation that supports QR payments using the Indonesian Standard Quick Response Code (QRIS). PT ABC is one of the banks that launched a QR payment feature on mobile banking with QRIS standards to make it easier for customers to make payment transactions at various merchants. In its implementation, the interest of QR payment users still tends to be small, so an analysis of the interests of QR payment users is carried out. The purpose of this study is to analyze the factors that influence user interest by using a modified UTAUT model. The UTAUT model was modified by adding variables to perceived trust, perceived risk, perceived regulatory support, and promotional benefits. The population taken is the company's customers in the DKI Jakarta area and it takes 403 samples for this case study. The results of empirical analysis show that 8 out of 12 hypotheses are considered proven where business expectations, social influence, perceived trust, perceived risk, perceptions of regulatory support, promotion benefits, age-moderated performance expectations, and age-moderate effort expectations have a significant effect on behavioral intentions, while performance expectations, facilitation conditions, business expectations are moderated by experience and social influence.

Purpose: Obesity among children from low-income families is becoming a social problem. The aim of this study was to evaluate the effectiveness of an obesity prevention program that included physical activity, nutrition education, behavioral modification, and primary caregiver participation components among children from low-income families. Methods: The study analyzed a nonequivalent control group using a pretest-posttest design. A total of 77 children were recruited from six community childcare centers using purposive sampling. For the intervention group (n=40), the pretest was administered before the combined intervention program involving the participants' primary caregivers was conducted for 8 weeks. The posttest was conducted immediately after the program and again four weeks after the program. Results: Flexibility (F=4.64, p=.020), muscular endurance (F=11.22, p<.001), nutritional knowledge scores (F=4.79, p=.010), body image satisfaction scores (F=4.74, p=.012), and self-esteem scores (F=3.81, p=.029) showed significant differences and interactions between group and time for the intervention and control groups. Conclusion: Strategies to actively engage the primary caregivers of low-income families in children's obesity programs are needed. Obesity prevention programs for children based on the program in this study should be routinely developed, and continuing attention should be given to children from low-income families.

Utilization of fiber beam-column element has gained considerable attention in recent years due mainly to its ability to model distributed plasticity over the length of the element through a number of integration points. However, the relatively high sensitivity of the method to modeling parameters as well as material behavior models can pose a significant challenge. Residual drift is one of the seismic demands which is highly sensitive to modeling parameters and material behavior models. Permanent deformations play a prominent role in the post-earthquake evaluation of serviceability of bridges affected by a near-fault ground shaking. In this research, the influence of distributed plasticity modeling parameters using both force-based and displacement-based fiber elements in the prediction of internal forces obtained from the nonlinear static analysis is studied. Having chosen suitable type and size of elements and number of integration points, the authors take the next step by investigating the influence of material behavioral model employed for the prediction of permanent deformations in the nonlinear dynamic analysis. The result shows that the choice of element type and size, number of integration points, modification of cyclic concrete behavior model and reloading strain of concrete significantly influence the fidelity of fiber element method for the prediction of permanent deformations.

Insomnia in patients with hematopoietic stem cell transplantation(HSCT) has been underdiagnosed and undertreated. This study reviewed the frequency, characteristics, physical and psychological effects, and treatments of insomnia in HSCT patients to highlight clinical importance in this specialized population. Furthermore, the authors intended to suggest a model that would conceptualize insomnia in the context of HSCT. In the pre-transplant period, about half of patients with HSCT suffered from sleep disturbance. A substantial number of patients experienced distressing insomnia during the HSCT procedure and recovered to the level of the pre-transplant period. However, sleep disruption could be a chronic symptom in HSCT survivors and could negatively impact quality of control, cancer-related fatigue(CRF), immune function, and psychological distress. The 3P's model(Predisposing, Precipitating, Perpetuating) explains insomnia in cancer population and could be also relevant to HSCT patients with specific consideration of CRF, graft-versus-host diseases, specific properties of hematological disease, and protective isolated milieu. Effective treatment of insomnia in HSCT includes non-pharmacological(e.g., cognitive behavioral therapy, environmental modification) and pharmacological interventions. The decision of pharmacological treatment should be based on the issue of safety due to high risk of potential drug-drug interactions. Screening, treatment, and further research of insomnia in HSCT patients using validated subjective and/or objective measures are warranted.

Dementia is a clinical syndrome characterized by a cluster of symptoms and signs that manifest as difficulties in cognitive functions such as memory, psychological and psychiatric changes, and impairments in activities of daily living. As a result of worldwide trends of population aging, dementia has had a huge impact on public health in almost all countries. Disease modification therapies for dementia have not yet been developed. However, pharmacotherapy is essential in patients with dementia to combat delays in their cognitive and functional decline. In this article, we review the current pharmacotherapy for dementia. Three acetylcholinesterase inhibitors-donepezil, rivastigmine, galantamine-and memantine are the only medications that have been approved for the treatment of dementia. We present the indications, dose recommendations, side effects, and criteria for National Health Insurance coverage in Korea of these medications for dementia treatment. Although the Ministry of Food and Drug Safety in Korea has not approved any medications for managing the behavioral and psychological symptoms of dementia, some antipsychotics and antidepressants have been studied and used clinically for those purposes. Clinicians may consider vitamin E, Ginkgo biloba extract, choline alfoscerate, or omega-3 fatty acids as additional treatment options. Non-steroid anti-inflammatory drugs, estrogen hormone therapy, and statins are not generally recommended for dementia treatment. We believe that our findings will aid clinicians in the treatment of patients with cognitive decline.

Purpose: This study targeted female university students in their 20s and created an antioxidant improvement program with a health contract, one of the behavioral modification therapies, based on King's (1981) 'goal attainment theory.' The aim of this study is to investigate the effects of physiological indicators, eating habits, dietary attitudes, and health behaviors by conducting a walking exercise and anti-oxidation diet program with reinforcement therapy. Methods: This study had a nonequivalent control group pretestposttest design. There were a total of 50 participants, with 25 participants in the experimental group and 25 participants in the control group and the study period was 10 weeks. The antioxidant improvement program consisted of walking and antioxidant diet education with health contracts. Data analysis was statistically processed using the SPSS/WIN 24.0 program. Results: The program showed a high achievement rate by providing continuous motivation and positive reinforcement during the program, and it affected the eating habits, dietary attitudes, and health behavior. Besides, physiological variables, such as antioxidant indices and body composition showed positive changes. Conclusion: This study, based on the goal attainment theory, confirmed that antioxidant improvement program is an effective nursing intervention for continuous health promotion through interaction and exchange between healthy participants and researchers.

This study aimed to know the response of deep-sea squid Sthenoteuthis oualaniensis to the light colors of the artificial bait. This experiment used the commercial artificial flashlight baits commonly sold in the fishing shop. The bait has several different light color combinations. The light colors were modified into several light colors by inactivating certain colors and used as treatments. The study is expected to be able to find flashlight bait's most effective color for squid fishing. We applied red-green, green, blue, and commercial bait lights in this study. Each treatment has 3 replications. The effect was expressed as the amount of squid caught. Data were analyzed by one-way analysis of variance. Results showed a significant effect on the number of squid catches. There was significantly different squid catches among the treatments. It indicates that this artificial flashlight bait could be developed to maximize squid catches. This finding can be used for the local fishermen's income and the squid fisheries development.

The prevalence of obesity in children and adolescents is increasing worldwide. Obesity in children and adolescents not only increases the risk of transitioning to obesity in adulthood but also increases the risk of cardiometabolic diseases such as high blood glucose, high blood pressure, dyslipidemia, fatty liver, and hyperinsulinemia during childhood. The goal of treating obesity in children and adolescents is not to focus on weight loss but to help children reach a healthy weight while maintaining normal growth appropriate for their age and sex. To achieve this goal, regular physical activity and exercise, dietary modification, improvement of obesity-prone environmental factors, and behavioral changes are required for a healthy lifestyle. If appropriate weight control is not achieved through lifestyle modifications, pharmacotherapy may be considered for adolescents with severe obesity aged 12 and above. Recent clinical trials have reported the efficacy and safety of pharmacotherapy in severely obese adolescents. Currently, two medications can be prescribed in Korea for patients with obesity aged 12 and above: Orlistat and Liraglutide. However, despite effective weight control through drug treatment, body weight may increase again after treatment discontinuation. Therefore, it is crucial to evaluate adherence to health behaviors during visits and continue to educate on lifestyle modifications, even during pharmacotherapy, to minimize weight regain.
