스마트폰(smartphone)은 휴대전화에 인터넷 통신과 정보검색 등 컴퓨터 지원 기능을 추가한 지능형 단말기로서 사용자가 원하는 어플리케이션(application)을 설치할 수 있는 것이 특징으로, 현 시대에 있어 하나의 문화가 되었을 정도로 크나큰 이슈가 되고 있고, 어플리케이션 개발 시장도 활발해졌으며, 크게 성장하고 있다는 점이다. 대중교통정보 어플리케이션의 사용 빈도가 높은 편이긴 하나, 유동인구 빈도수가 높은 수도권과 광역시 지역 중심으로 제공되는 있는 실정이다. 본 논문에서는 GPS(Global Positioning System) 기능이 활성화 되지 않은 지방지역 실정을 고려하여 안드로이드 플랫폼(android platform)을 이용한 스마트폰 기반 스쿨버스 어플리케이션 설계와 구현을 제안하려 한다.

This study attempted to verify the relationship between job burnout and organizational citizenship behavior among South Korean soldiers in the Navy force by applying the Job Demands-Resource Model and Conservation of Resource Theory, and the moderated mediating effect of social capital through the work engagement and smartphone use. The mediating effect of work engagement and the moderating effect of social capital via smartphone use were examined in the relation between job burnout and organizational citizenship behavior. We combine the mediation effect model and the moderation effect model and tested the moderated mediation effect. To perform this study, the survey was conducted on the navy soldier on duty, and total of 324 data were analyzed. The results of this study were as follows: the complete mediation effect of work engagement in the relation of job burnout and organizational citizenship behavior was verified, social capital via smartphone use moderated the relation between job burnout and work engagement, and the moderated mediation effect of social capital via smartphone use in the relation between job burnout and organizational citizenship behavior through work engagement was identified. Based on the results, implications, limitations, and future research directions of the current study were discussed.

Friendships play a very important role during high school. However, unstable friendship quality can induce negative problems such as psycho-emotional problems. This problem can be highlighted based on the characteristics of high school girls who consider the psycho-emotional aspects of friendships more than men do. This study was aimed to analyze the effect of level of quality of friendship on the level of smartphone overdependence of female high school students. Study subjects were 51 female high school students attending the W high school in J city. The assessment of quality of friendship was used by Korean ver. of Friendship Quality Questionnaire. The quality of friendship is 21 items, and the higher the score on a 5-point scale, the higher the quality of friendship. The assessment of smartphone overdependence was used by Smartphone Overdependence Scale. Smartphone overdependence has 10 questions, and a high score on a 4-point scale means a high level of smartphone overdependence. As the results, the negative effect (-) of the level of the quality of friendship on the level of smartphone overdependence. These results indicated that if the level of quality of friendship increase, the level of smrtphone overdependence decrease. Thus, in the process of educational and practical approach for the female high school student, these results should be considered and the approach to improve the quality of friendship should be needed. In follow-up studies, it is necessary to expand the range of subjects and compare and analyze them with various subject groups. In-depth analysis studies should be conducted considering various variables that can affect the relationship between smartphone overdependence and the quality of friend relationships.

Interest in the augmented reality is growing and increase of Smartphone is changing people's life style. The purpose of this study is to explore application method of image restoration based on augmented reality to museum education. Museum is the proper place that audience, including students could learn culture and history of past time. This study suggests that using smartphone application which is used by image restoration with augmented reality is efficient to museum audience's understanding and interest. A game design for domestic museums is planned. Smartphone application which is used by image restoration with augmented reality also could be utilized for exploring historic sites or enjoying local festivals.

Recently with smartphones and tablets, personal earphones have been using to utilize a wide range of multimedia services. Especially smartphones sold domestically provide earphones as necessaries. As a life style listening to music through smartphones and tablets has been spread widely, there has been in increasing demand of earphones necessary for enjoying music anytime and anywhere. This paper has simplified the complex performance test processes to inspect defective products when producing a large amount of earphonesand has improved the existing performance test processes to reduce the costs and time for the performance test of earphones. In this paper, the improved performance test processes through developing the performance test equipment of earphones can reduce the performance test inspectors, cut down the performance test time, and increase the daily amount of the performance test.

Purpose : The purpose of this study was to investigate the double mediating effect of ego-resilience and impulsivity in the effects of smartphone addiction on depression among office workers. Research design, data and methodology : The subjects of this study were office workers working in four cities: Seoul, Daejeon, Chungnam, and Chungbuk Province, and the total number of respondents was 286. Descriptive statistics, difference test (t-test, ANOVA), correlation analysis, and double-mediated effect analysis were used for statistics. Results : The results of this study are as follows. First, as a result of the difference analysis, there was no difference in depression according to the general characteristics of the subjects of this study, such as gender, age, marital status, and salary. Second, as a result of correlation analysis, smartphone addiction showed a negative correlation with ego-resilience, and a positive correlation with impulsivity and depression. Also, ego-resilience showed negative correlation with impulsivity and depression. Impulsivity showed a positive correlation with depression. Third, as a result of dual mediating effect analysis, it was found that ego-resilience and impulsivity played double-mediated role between smartphone addiction and depression. Conclusions : Based on the results of this study, theoretical measures centered on ego-resilience were discussed and presented in order to positively induce the decrease in impulsivity and depression due to smartphone addiction among office workers.

증강현실이란 가상현실을 활용하되 현실세계에 가상현실을 일부 겹쳐 보이게 하는 컴퓨터 그래픽 기법으로, 본 논문에서는 증강현실을 활용하여 여행 가이드북을 설계하고 구현하였다. 스탬프 투어 기능은 별도의 템플릿이나 종이 없이 스마트 폰 어플리케이션만으로 증강현실로 보이는 스탬프를 터치하는 방식으로 스탬프를 모을 수 있게 설계하였다. 문화재 해설 기능의 경우 궁 혹은 박물관 내에서 활용이 가능하며, 가상현실로 궁의 각 시설이나 문화재의 제작 목적, 사용방법에 대해서 영상으로 제공하여 이해도와 관심도를 높일 수 있다는 특징이 있다. 두 기능 모두 스마트 폰 어플리케이션 설치만으로 가능한 기능으로 시간의 제약이나 특별한 장비 없이 가상현실로 활용한 여행을 할 수 있다는 점에서 사용자에게 편리함을 줄 수 있다.
