In this paper, we implemented an e-mail and chat program (client) for communication between mobile devices and PCs based on WIPI a South Korea's open wireless platform form developing device and content independent software to break from the way of developing contents that is dependent on different wireless platforms to each mobile communications company. While traditional e-mail and chat programs are written for PC-to-PC communication, we develop them for mobile-to-PC and mobile-to-mobile communications, and we expect to see various mobile contents in the future.

Objectives: This study was conducted to investigate providers' perspectives on current challenges in implementing a program for prevention and management of childhood obesity and adoption of mobile phone as a potential solution of leveraging multimodal delivery and support in a school setting. Methods: The qualitative data were collected through face-to-face in-depth interviews with 23 elementary-school teachers, 6 pediatricians, and 6 dieticians from community health centers and analyzed using a qualitative research methodology. Results: Current challenges and potential solutions of obesity-prevention and -management program for obesity program for elementary school children were deduced as two themes each. Lack of tailored intervention due to limited recipient motivation, lack of individualized behavioral intervention, and different environmental conditions can be solvable by mobile technology-based personalized intervention which brings about interactive recipient participation, customized behavioral intervention, and ubiquitous accessibility. Lack of sustainable management due to stigmatization, limited interactions between program providers and inconsistent administrative support can be handled by multimodal support based on school setting using mobile platform providing education of health promoting behaviors toward larger scale and interactive networking between program participants, and minimizing administrative burden. Conclusions: Adoption of mobile-based health management program may overcome current limitations of child obesity program such as lack of tailored intervention and sustainable management via personalized intervention and multimodal supports although some concerns such as increased screen time need to be carefully considered in a further study.

모바일 게임 시장 규모와 인구가 증가하고 동시에 모바일 게임의 생명주기가 크게 길어지면서 PC 기반 온라인 게임에서 나타났던 오토 프로그램 문제가 모바일 게임에서 그대로 재현되고 있다. 사용자들은 오토 프로그램 실행을 위해 안티 바이러스 프로그램의 경고를 무시하거나 심지어 안티 바이러스 프로그램을 삭제하기 때문에, 오토 프로그램이 게임 관련 기능 외에 악성 행위를 수행할 경우 게임 이용자들은 위협에 무방비로 노출될 수 있다. 본 논문에서는 장기간 대규모의 사용자를 확보하고 있는 대표적인 모바일 게임인 클래시 오브 클랜의 오토 프로그램 7종을 대상으로 악성 행위 유무를 분석하고, 이를 바탕으로 향후 발생 가능한 보안 위협과 대응방안을 제시하였다. 높은 인기를 가진 특정 모바일 게임의 오토 프로그램들을 일괄 분석함으로써 개발 플랫폼, 동작 방식 등 오토 프로그램의 최신 동향을 파악하였고, 향후 오토 프로그램의 변화 양상 예측 및 잠재적 위협을 사전에 차단할 수 있는 방안을 제시하였다.

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

Purpose: The purpose of this study was to develop a mobile health lifestyle program for university students and to verify its effectiveness. Methods: The program was developed based on Jung's teaching-learning system design model. The research used a non-equivalent control group pretest-posttest non-synchronized design. Data were collected from October 20 to December 5, 2018. To verify the effects of the program, the knowledge, self-efficacy, and intention to plan health lifestyle and health lifestyle behavior were measured. A two hour health lecture and a mobile health lifestyle program were delivered for 3 weeks to 23 students in the experimental group. 19 students in the control group received only a two hour health lecture. Results: The experimental group showed significantly higher scores on knowledge (F=4.63, p=.038), intention to plan health lifestyle (F=14.44, p<.001), and health lifestyle behavior (F=46.80, p<.001). However, the score on self-efficacy was not significantly different (F=2.65, p=.112). Conclusion: It was confirmed that the mobile health lifestyle program can be useful in increasing the level of knowledge, intention and behavior of health lifestyle among university students. Therefore, the mobile health lifestyle application can be used as a supporting resource to enhance the health promotion for university students.

Purpose: The purpose of this study was to examine the effects of a mobile application on quality of life, wellness, and preventive behaviors against dementia among older adults who use senior citizen centers. Methods: Seventy-two older adults who used senior citizen centers were allocated to an intervention group (n = 36) and a control group (n = 36). The experimental treatment involved a cognitive enhancement program for preventing dementia using a mobile application for 12 sessions over 6 weeks. Data were analyzed using the t-test, chi-square test, Fisher's exact test, paired t-test, and independent t-test. Results: The cognitive enhancement program based on a mobile application was effective for wellness (t = -3.87, p < .001) and preventive behaviors against dementia (t = -3.98, p < .001) for older adults who used a senior center. Conclusion: The mobile application-based cognitive enhancement program developed in this study is recommended as an effective intervention for dementia prevention in older adults.

Purpose: This study analyzes the effects of variables affecting e-satisfaction and e-loyalty in e-commerce. Research design, data, and methodology: A survey was conducted to 384 Indonesia online shopping mobile application users. The questionnaire construct was designed based on several independent variables, such as application attractiveness, application functionality, and customer service on e-satisfaction and e-loyalty. E-satisfaction was positioned as an intervening variable to determine the effect on e-loyalty. Results: Application attractiveness, application functionality, and customer service shown positive effect on e-satisfaction in online shopping mobile application. At the same time, e-satisfaction also affected e-loyalty significantly as referred in previous studies. However, application attractiveness, while showed positive effect on e-satisfaction, in contrary with previous study does not showed very significant effect. Conclusion: Application functionality significantly influences users satisfaction compared to application attractiveness. E-satisfaction mediates as a factor between visual design, information access, and transaction in online shopping mobile application, which stimulates user loyalty. The study findings' can be a reference for companies to create and maintain users' satisfaction and loyalty via different aspects of mobile application. Further research should be conducted on other field of study as the industry has different aspects that affects user loyalty.

장애학생들에게 주의집중은 매우 중요한 교육요소이다. 본 연구에서는 학습 장애학생들의 특성을 분석한 후, keller의 동기유발학습이론인 ARCS (Attention, Relevance, Confidence, Satisfaction)모델의 동기유발 요소와 정착학습이론의 앵커라는 자발적 인지학습을 위한 매개체, 그리고 방법적 측면의 모바일이라는 방법을 적용한 m-ARCS이론을 제시하였다. 또한, m-ARCS이론에 의해 구현한 모바일 앵커프로그램은 학습 장애학생의 특성을 고려하여 설계하여 그들의 주의집중력을 향상시킬 수 있다. 이처럼 m-ARCS이론에 의한 모바일 앵커프로그램을 구현하여 실제 학습장애 학생에게 적용한 결과, 첫째, 학습에 대한 재미와 흥미를 느끼며 동기유발 및 주의집중력이 향상 효과가 있었다. 둘째, 학습과정에서 의 성공경험으로 인해 학습에 대해 전보다 자신감이 향상되었다. 셋째, 모바일 앵커프로그램을 통해 활동한 학습내용들을 자연스럽게 습득함으로써 기초 기본 학습능력이 향상되었다.
