Objectives: To identify the current status of smartphone usage and to describe the needs for smartphone-based cardiac telerehabilitation of cardiac patients. Methods: In 2016, a questionnaire survey was conducted in a supervised ambulatory cardiac rehabilitation (CR) program in a university affiliated hospital with the participation of heart failure or heart transplantation patients who were smartphone users. The questionnaire included questions regarding smartphone usage, demands for smartphone-based disease education, and home health monitoring systems. Results were described and analyzed according to principal diagnosis. Results: Ninety-six patients (66% male; mean age, $5{\pm}11$ years), including 56 heart failure and 40 heart transplantation patients, completed the survey (completion rate, 95%). The median daily smartphone usage time was 120 minutes (interquartile range, 60-300), and the most frequently used smartphone function was text messaging (61.5%). Of the patients, 26% stated that they searched for health-related information using their smartphones more than 1 time per week. The major source of health-related information was Internet browsing (50.0%), and the least sought source was the hospital's website (3.1%). Patients with heart failure expressed significantly higher needs for disease education on treatment plan, home health monitoring of blood pressure, and body weight (${\chi}^2=5.79$, 6.27, 4.50, p < 0.05). Heart transplantation patients expressed a significant need for home health monitoring of body temperature (${\chi}^2=5.25$, p < 0.05). Conclusions: Heart failure and heart transplantation patients show high usage of and interest in mobile health technology. A smartphone-based cardiac telerehabilitation program should be developed based on high demand areas and modified to suit to each principal diagnosis.

Purpose: This study conducts a comparative evaluation of the skin dose in CyberKnife (CK) and Helical Tomotherapy (HT) to predict the accurate dose of radiation and minimize skin burns in head-and-neck stereotactic body radiotherapy. Materials and Methods: Arbitrarily-defined planning target volume (PTV) close to the skin was drawn on the planning computed tomography acquired from a head-and-neck phantom with 19 optically stimulated luminescent dosimeters (OSLDs) attached to the surface (3 OSLDs were positioned at the skin close to PTV and 16 OSLDs were near sideburns and forehead, away from PTV). The calculation doses were obtained from the MultiPlan 5.1.2 treatment planning system using raytracing (RT), finite size pencil beam (FSPB), and Monte Carlo (MC) algorithms for CK. For HT, the skin dose was estimated via convolution superposition (CS) algorithm from the Tomotherapy planning station 5.0.2.5. The prescribed dose was 8 Gy for 95% coverage of the PTV. Results and Conclusions: The mean differences between calculation and measurement values were $-1.2{\pm}3.1%$, $2.5{\pm}7.9%$, $-2.8{\pm}3.8%$, $-6.6{\pm}8.8%$, and $-1.4{\pm}1.8%$ in CS, RT, RT with contour correction (CC), FSPB, and MC, respectively. FSPB showed a dose error comparable to RT. CS and RT with CC led to a small error as compared to FSPB and RT. Considering OSLDs close to PTV, MC minimized the uncertainty of skin dose as compared to other algorithms.

Due to the routine nature of social distancing in accordance with the COVID-19 pandemic, the logistics industry is under rapid development, given that offline demand is focused on online platforms. The number of warehouse workplaces and workers are steadily increasing per annum, and the industrial accident rate of transportation, warehouse, and telecommunication industries to which warehouse employees belong is higher than the total industrial accident rate in Korea. In previous studies, warehouse workers reported exposure to health hazards such as musculoskeletal disorders due to the handling of heavy objects and improper working postures. Accordingly, in this study, a survey was conducted to investigate symptoms of musculoskeletal disorders with focus on parcel delivery workers nationwide. The questionnaire included a musculoskeletal disorder symptom survey table to identify information such as worker occupational history, work type, and signs or symptoms of musculoskeletal disorders. Survey response data from 453 people were obtained to determine the influence of delivery business characteristics on occupational musculoskeletal disorders, and the influencing factors were analyzed. Based on the results, in the analysis of pain with respect to body part, the duration, degree, and frequency of pain were highest in the leg part, and as a result, the average value for the leg part exhibited a significant difference from those of other body parts. In addition, 52.32% of workers exhibited symptoms of musculoskeletal disorders, and a high number of patients with musculoskeletal disorders was observed in the work group with less than three years of service and with ages ranging from 30-39. The results of this study can serve as basic data for the derivation of a management plan that meets the characteristics of musculoskeletal disorders that impact logistics workers overburdened with work due to the rapid increase in parcel delivery volume in accordance with an increase in online consumption.

Purpose: In this study, the dosimetric characteristics of lung stereotactic body radiotherapy (SBRT) plans using the new Halcyon system were analyzed to assess its suitability. Methods: We compared the key dosimetric parameters calculated for the Halcyon SBRT plans with those of a conventional C-arm linear accelerator (LINAC) equipped with a high-definition multileaf collimator (HD-MLC)-Trilogy Tx. A total of 10 patients with non-small-cell lung cancer were selected, and all SBRT plans were generated using the RapidArc technique. Results: Trilogy Tx exhibited significant superiority over Halcyon in terms of target dose coverage (conformity index, homogeneity index, D_{0.1 cc}, and D_95%) and dose spillage (gradient). Trilogy Tx was more efficient than Halcyon in the lung SBRT beam delivery process in terms of the total number of monitor units, modulation factor, and beam-on time. However, it was feasible to achieve a dose distribution that met SBRT plan requirements using Halcyon, with no significant differences in satisfying organs at risk dose constraints between both plans. Conclusions: Results confirm that Halcyon is a viable alternative for performing lung SBRT in the absence of a LINAC equipped with HD-MLC. However, extra consideration should be taken in determining whether to use Halcyon when the planning target volume setting is enormous, as in the case of significant tumor motions.

Health is easily overlooked because it doesn’t be changed good or bad due to sudden effort or indifference unexpectedly but kept in daily life. Especially, schoolchildren period, an important lifetime to develop both physically and mentally needs to be helpful to promote the growth of the body and keep well-balanced mind through balanced and nourishing diet. The purpose of this study was to develop nutrition education contents for discretional activities in elementary school. The present educational contents about food and nutrition was analysed in the curriculum of elementary school. The results showed the Korean language(20.8%) included an highest ratio in educational contents about food and nutrition, the next was the courses of physical education and wise life(18.1%, each). As the educational contents about food and nutrition in the textbook were dealt with food information (20.8%), Health․Disease(15.3%), and correct dietary habits by order. We could found more contents in the text for the higher classes than for the lower classes. But the most of the contents appeared lack of structure, profundity and continuity for the systematic nutrition education in its entirety. The developed nutrition education contents for discretional activities in this study consist of korean dinning cultures and foreign dinning cultures, correct dinning etiquette, how to choose healthy food, personal sanitary and health, nutrients and food tower, and problem for children’s nutrition as main subject. This six main subjects were composed of 23 subtitles. The teaching manual consisted of the educational goal, background, teaching plan and effect-evaluation plan, and the notice point for the effective lesson. The teaching plan was made for 30 hours and consisted of cooking course, singing/making lyrics, games in nutrition, debate on dietary habit, and role play etc which are oriented to practical learning. We intended to develop this program that attempts to improve in dietary habit of schoolchildren. It is because once formed an adults dietary habit is difficult to change. Schoolchildren’s period is the best adjustable stage. Therefore, nutrition education in elementary stage can change to dietary habit and build the awareness of health.

Background: The effects of home nursing intervention on the quality of life in patients with nasopharyngeal carcinoma (NPC) after radiotherapy and chemotherapy are unclear. According to the characteristics of nursing home patients with nasopharyngeal carcinoma, we should continuously improve the nursing plan and improve the quality of life of patients at home. Materials and Methods: We selected 180 patients at home with NPC after radiotherapy and chemotherapy. The patients were randomly divided into experimental and control groups (90 patients each). The experimental group featured intervention with an NPC home nursing plan, while the control group was given routine discharge and outpatient review. Nursing intervention for patients was mainly achieved by regular telephone follow-up and home visits. We use the quality of life scale (QOL-C30), anxiety scale (SAS) and depression scale (SDS) to evaluate these patients before intervention, and during follow-up at 1 month and 3 months after the intervention. Results: Overall health and quality of life were significantly different between the groups (p<0.05), Emotional function score was significantly higher after intervention (p<0.05), as were cognitive function and social function scores after 3 months of intervention (p<0.05). Scores of fatigue, nausea and vomiting, pain, appetite and constipation were also significantly different between the two groups (p<0.05). Rates of anxiety and depression after 3 months of intervention were 11.1%, 22.2% and 34.4%, 53.3%, the differences being significant (p<0.05). Conclusions: NPC home nursing plan could effectively improve overall quality of life, cognitive function, social function (after 3 months) of patients, but improvement regarding body function is not suggested. Fatigue, nausea and vomiting, pain, appetite, constipation were clearly improved. We should further pursue a personalized, comprehensive measurements for nursing interventions and try to improve the quality of life of NPC patients at home.

The purpose of this study was to investigate a plan of middle/high school foodservice systems which could properly provide nutrition for juveniles' health. Questionnaires were developed and distributed to: 245 middle schools with 271 parents, 328 students, 180 teachers, and 345 administrators; 163 high-schools with 223 parents, 466 students, 179 teachers, and 163 administrators in Seoul and Kyunggi province. The results of this study were as followed. For the desirable feeding type as in-school meal plan, 62.2% responded to the current elementary school feeing type:10.3% responded to a lunch-box prepared at home; and 38.0% responded to free dining out type. For a feeding operation type, school administrators, teachers and parents favored the current school feeding systems in elementary schools with proportion of 68.2%, 47.7%, and 87.6% as respectively. Also, 20.3% of school administrators, 22.6% of teachers, and 6.9% of parents preferred contract management. A total of 27.6% of teachers, 9.2% of school administrators, and 3.7% of parents responded to a lunch-box prepared at home. There was a significant difference between the responses for establishing the main body of financial burden to solve the problem of financial burden which could be the most obstacle to bring middle/high school feeding system into operation. For the management of school feeding systems when brought into operation, 88.7% out of 470 responded schools and 89.9% out of 227 responded teachers reported that an expert should manage school feeding systems. For futuristic direction, an effective joint cooking type between schools which may be the way to solve the difficulties in securing the appropriate space and to decrease the financial burden, the problem of transportation for delivering feeding products, low quality of feeding, and sanitation can occur. Therefore, the distance between schools which operate a joint cooking system will affect as a major factor. Furthermore, concrete examination of plans for introduction of various types of school feeding and institutional devices for management system and supervision of operation should become a condition precedent.
