This study aims to understand the relationship between the practice of physical activity guideline for adolescents presented by government agencies and smartphone problem experience. To that end, the association between the practice of physical activity guideline and smartphone variables was analyzed by utilizing 62,225 data from "2017 Youth Health Behavior Survey" and multiple regression analysis was conducted using the SPSS 23.0 program. The analysis showed that all physical activity variables, except for "physical activity for more than 60 minutes," have negative effects on the smartphone problem experience. In addition, students who practice physical activity guideline presented by government agencies, such as aerobic exercise, muscular exercise, participation in sports clubs, and sedentary behavior, experienced less smartphone problem compared to those who did not practice, which showed significant differences in gender. According to the results of this study, it is thought that academic in-depth research using this guideline and differentiated physical activity promotion programs by gender will be possible in order to prevent smartphone addiction.

This study was conducted to identify factors related to the problematic experiences of smartphone use among adolescents according to gender. The subjects of this study were 54,603 male and female adolescents. This study data was analyzed using SPSS 25.0 program. As a result of this study, the relevant factors for the problematic experiences of smartphone use among male students were academic performance, economic level, counselors, fast food consumption frequency, depression, suicidal ideation, suicide plan, happiness, subjective body image, stress, and smartphone usage time. Drinking and smoking were found to be significant related factors only for female students.

The purpose of this study was to examine the mediating effects of experiential avoidance on the relationships between life stress, depression and smartphone addiction in nursing college students. This study was conducted using a descriptive survey design. Participants were 283 nursing college students attending freshmen and sophomore yearsat one university in Jeollanam-do. Data were collected from September 1 to 15, 2015 using self-report questionnaires. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, hierarchical regression and Sobel test with SPSS 21.0. There were significant positive correlations between life stress, depression, smartphone addiction and experiential avoidance. Experiential avoidance partially mediated the relationship between life stress and depression of nursing students. Additionally, experiential avoidance partially mediated the relationship between their life stress and smartphone addiction. The results show that experiential avoidance plays a key role in psychopathology and grows with depression and smartphone addiction. Based on the present findings, nursing interventions should be developed to decrease experiential avoidance, with additional consideration towards the relationship between life stress and experiential avoidance, in order to prevent depression and smartphone addiction among nursing college students.

Recently the market of smart phone applications grows very fast. And users want more various and rich experiments using enhanced smart phone functions. But the development of smart phone applications is not an easy job. Specially to control smart phone sensors can be realized by using each native programming languages in experts level. Moreover the process needs separate development based on each smart phone OS. Development of the Web-based smart phone application using Web Common APIs, known as 'WebApp', is one of solutions to overcome these problems. The method includes interface constructions with HTML, and Web Common API calls and accesses to smart phone device APIs with Java scripts. In this paper, the experience in development of the smart phone e-book application is introduced, which is implemented with comport and OS independent WebApp development method.

최근 스마트폰의 과다 사용과 관련한 문제를 해결하기 위하여 스마트폰 디톡스라는 새로운 개입방법이 소개되고 있다. 스마트폰 디톡스는 마치 단식을 통해 몸에 있는 독소와 노페물을 제거하듯이 스마트폰 사용을 잠시라도 중단하고 내면의 모습을 돌아봄으로써 스마트폰을 건강하게 활용하여 신체적 정신적 사회적 건강을 실천하자는 취지이다. 이러한 흐름에 발을 맞추어 본 연구에서는 대학생들의 과다한 스마트 폰 사용을 개선하고 전인적인 건강(well-being)을 실천하기 위하여 "스마트폰 디톡스 프로그램"을 개발하고 그 효과를 확인하였다. 서울의 S대학교 16명의 대학생이 전체 프로그램을 완료하였으며, 각 회기별 자기평가보고서와 사전-사후 설문조사(스마트폰 중독척도 정신건강척도 긍정심리자본척도 자기생활관리척도)를 완성하였다. SPSS 23을 이용하여, 사전검사와 사후검사에서 변수 간의 차이를 확인하기 위해 Wilcoxon 부호순위검정을 시행하고, 각 척도들 사이의 관계는 피어슨 상관분석을 이루어졌다. 그리고 자기평가보고서는 각 회기 참여에 대한 질적 자료로 분석되었다. 그 결과, 개입 프로그램을 통해 스마트 폰 중독 및 정신 건강 점수가 유의미하게 감소하였으며, 자기 관리 및 긍정심리자본의 평균 점수가 증가하였다. 더불어 프로그램이 진행되는 동안이라도 스마트폰 사용을 중단하고 건강한 신체, 긍정적인 정신, 역동적인 대인관계를 경험하면서 스마트폰을 지혜롭게 사용하고 주변을 여유롭게 돌아보는 변화가 생겼으며, 대학생들의 생활에서 스마트폰을 건강하게 사용할 수 있는 모습이 확인되었다.

The purpose of the study is to verify whether literature therapy program for prevention of smartphone addiction is effective for adolescents. The subjects of this study were 150 students of J City, K middle school. After completing the program, they were conducted post-test for both the experimental and control groups. The study found that the program was effective in mitigating smartphone addiction but not in reducing the directed life problem. It was also found to be effective in reducing tolerance and loss of control and problems of withdrawal and emotional experience. The study suggests that institutional arrangements are needed for linking with related organizations in the region because it is difficult to effectively prevent the increasing problem of smartphone addiction unless an adolescents program for youth is linked to the school. Therefore, it is necessary to conduct parent education for prevention of smartphone addiction in computer curriculum of school subjects.

Smart-phones have become a vital part of our lives, paying a bill online, shopping using applications, using email and office applications. Therefore, the risk of the leakage of personal informations and the misuse of them becomes high, for the cost of loosing smart-phone. Many types of smart-phone security features such as password, slide-lock, and pattern lock have been introduced. However, those security locks make users not to easily access and use a smart-phone. There is tradeoff between security on one hand, and usability and cost on the other. This paper propose Self-Concealment to solve the tradeoff problem and demonstrate the effect through the experiment. In sum, Self-Concealment lowers smart-phone experience; however increases smart-phone use intension. This paper has implication for proposing new User Experience (UX) construct to resolve the trade-off between security and usability.
