This study was conducted to assess the needs of smartphone application development for self care performance of 374 patients with chronic hepatitis B. The mean age of the subjects was 46.2 years. The patients obtained information about chronic hepatitis B from the internet (41.3%), nurses or doctors (23.8%), television (15.6%), and smartphones (6.2%). The reason that the information about hepatitis B didn't come from a smartphone were 'Lack of useful applications' (75.9%), 'Could not believe the information' (15.0). If the application is developed, subjects replied 'Frequently use' (59.9%), 'When needed' (33.2%). The desired contents were 'Knowledge of disease' (27.1%), 'Drug calender' (16.8%), 'Reference of information' (15.5%), 'Record of lab data' (14.6%). Ability to use the smartphone, depended on age and level of education, however the needs for the development of the smartphone application, there were not differences. Also, there were different desired contents of application, depended on age and level of education. Therefore, when developing smartphone applications for self care performance of chronic hepatitis B patients considering educational level and age, it could be widely utilized as a tool which can help to the self care performance of chronic hepatitis B patients.

This study analyzed the correlation between adolescents' smartphone addiction as well as depression, self-esteem, and self-regulation based on QEEG (Quantitative Electroencephalogram) analysis. The study period was from March 19 to July 12, 2019, and the subjects were 76 students at P Middle School in Gyeonggi-do (normal group 47, risk group 29) who filled out a questionnaire and were subjected to quantitative EEG. The data analysis was performed via frequency analysis, independent t-test, correlation analysis, and path analysis of the IBM SPSS Statics 21.0 program. First, smartphone addiction had a positive correlation with depression. Second, smartphone addiction showed a negative correlation with self-esteem and α wave. Third, depression showed a negative correlation with self-esteem, which did not show a significant correlation with self-regulation. Fourth, depression was higher in the risk group than the normal group. For self-esteem, the normal group scored higher than the risk group. Self-regulation showed higher significant differences with the normal group than the risk group. Fifth, for α wave and SMR, the normal group scored higher than the risk group. Sixth, α waves had a negative effect on smartphone addiction. This study is meaningful in that it applied a brain science approach using quantitative analysis for objective evaluation of smartphone addiction.

In this paper we propose a human body tracking method for application of smartphones. The conventional human body tracking method is divided into a sensor-based method and a vision-based method. The sensor-based methods have a weakness in that tracking accuracy is low due to cumulative error of position information. The vision-based method has no cumulative error, but it requires reduction of the computational complexity for application of smartphone. In this paper we use the improved HOG algorithm as a human body tracking method for application of smartphone. The improved HOG algorithm is implemented through downsampling and frame sampling. Gaussian pyramid is applied for downsampling, and uniform sampling is applied for frame sampling. We measured the proposed algorithm on two devices, four resolutions, and four frame sampling intervals. We derive the best detection rate among downsampling and frame sampling parameters that can be applied in realtime.

Currently, information society is rapidly changing and demands innovation and creativity in various fields. Therefore, the importance of mathematics, which can be the basis of creativity and logic, is emphasized. The purpose of this paper is to develop a math education application that can further expand the logical thinking of mathematics and allow voluntary learning to occur through the use of readily available teaching aid for children to form motivation and interest in learning. This paper provides math education applications using a smartphone and blocks for children. The main function of the application is to shoot with the camera and show the calculated values. When a child uses a block to make a formula and shoots a block using a camera, you can directly see the calculated value of your formula. The preprocessing process, text extraction, and character recognition of the photographed images have been implemented using OpenCV libraries and Tesseract-OCR libraries.

It is known that the smart education has a positive impact of critical thinking skills and problem solving, communication and collaboration, creativity and innovation in the 21st century. However, some people concern about the adverse effects of smart education such as smart devices addiction and health problems. In this study, we conducted the adverse effects of education using smart devices on students. The questionnaire survey was conducted and analyzed for students in 9 schools at A city(four elementary schools, three middle schools, two high schools) that are receiving smart education. The types of adverse effects of smart education includes smartphone addiction, lack of information ethics, health problems, and lack of social and learning ability. We showed the differences each item compared among elementary school, middle school and high school about adverse effects of smart education. The result of survey didn't have any adverse affect of smart education such as internet addiction or smartphone addiction. However in order to protect the copyright, the school needs to fight against indiscriminated downloads and perform the information ethics education. Plus we surely need to be more open-minded in reading and exercise at school and home.

Construal level theory (CLT) have been researched in wide range of disciplines such as marketing, organizational study, psychology, or education. Current study asserts that CLT would explain the effect of different devices of PC and smartphone on interaction between human-computer interfaces and information systems use. In CLT, those who are far from an object in terms of physical, temporal, social or psychological distance, they construe their understanding as abstract (high level) and vice versa. We hypothesized different size of digital device will increase psychological distance and result in behaviors that correspond to present construal level. The analysis result shows that users of PC recognized that they are socially distant from the device and those of smartphone felt that they are socially close to the device. However, the device did not have significant effect on attention to essential information, advertisement preference, and immediacy. The implication to academia, practice and future research and limitations are also discussed.

Purpose: The purpose of this study was to develop a smartphone application and evaluate it's effectiveness and usability for promoting bone health in Korean young adult women. Methods: A smartphone application was developed covering exercise, nutrition, and health habits related to bone health. A pilot testing was conducted using a one-group pre/posttest design. A total of 22 female college students with low bone mass participated in the 8-week use of a pilot testing. Results: The "Strong bone Fit body (SbFb)" application was developed using Android platform. In the pilot testing, bone mineral density, serum CTX, and 25 (OH)Vit.D were significantly decreased. There is no significant change in serum osteocalcin and calcium. Serum phosphorus concentration, nutrient intakes (fiber, VitB6, and pantotenic acid), and all bone composition profiles were significantly increased. Bone-health knowledge was significantly increased but no change in health belief and self-efficacy. Conclusion: The results of this pilot testing suggest the effectiveness of the SbFb application to enhance and promote self-managing abilities for bone health. It can provide continuous feedback and high-quality bone health information. However, some contents and working methods of the application need to be modified and its effectiveness on bone health requires further investigations.

The purpose of this study was to raise validity of the result through using national data, to analyze the effect of children's smartphone addiction on aggression and moderating effect of parenting styles on the relationship between children's smartphone addiction and aggression. The data were obtained from 4th waves of KCYPS(Korean Children Youth Panel Study), and 1,686 4th graders in elementary schools who have smartphone were analysed. To achieve the purpose, this study executed frequency analysis, descriptive statistic, and hierarchical multiple regression analysis through SPSS 21.0. The results of this study are as follows: First, the higher children's smartphone addiction level, the higher children's aggression goes. Second, parents' supervision, affection, neglect have moderating effects on the relationship between children's smartphone addiction and aggression which means parenting styles could reduce children's aggression despite serious smartphone addiction. Based on these results, this study suggests that the combination of preventive discipline of smartphone addiction and parental education program is needed to reduce children's aggression which is main factor of bullying. In addition, this study suggests the establishment of special arrangement such as 'shut down' for smartphone addiction prevention.
