The purpose of this study is to investigate the usability and user interface in different types of mobile phones. KLM(key-stroke-level model) model estimation and observation values were calculated to perform 11 functional factors in 4 ordinary mobile phones and 4 smart phones. In results, it was found that the usability of ordinary phone is superior to smart phone in basic and simple function likes phone call. On the contrary, the usability of smart phone is superior to memorizing and picturing function. Current results can be used to anticipate the future effort to improve user interface design especially in smart phone.

This study verified theoretical model to explain adolescents' addictive use of smartphone. I used the data of 679 middle and high school students among 2013 internet addiction survey of National Information Society Agency(NIA). This study utilized structural equation modeling analysis to compare a suggestive model and alternative model. According to the final model, higher the satisfaction of family relationship, the addictive use of smartphone and emotional problems of adolescents were reduced. And, higher the addictive use of smartphone, higher the emotional problems of adolescents. Also, family relationship affects emotional problems via addictive use of smartphone. While, in the alternative model, path from amount of smartphone use to addictive use of smartphone was not significant. Results of this study suggest that family relationship variable may play an antecedent factor of addictive use of smartphone and emotional problems of adolescents and control of smartphone use is important to keeping a mental health of adolescents.

In recent years, using a smart phone that can access the Internet becomes routine in society through development of information and communication technology. On land, as especially actual accidents and research results show risk that using the smart phone while driving at the same time, and there are traffic laws and regulations that restriction of using of smart phone. But the regulations on the use of smart phones at sea is incomplete state. On this paper. We invested present status of use and reality of smart phone at sea and analyzed the subjective risk for judging to apply to regulation. And we analyzed risk quantitatively by using the simulation experiment; it Suggested a direction of guideline for use of smart phone at sea.

Smartphone use has become a part of everyday life, not only for adolescents but also for elderly and older people. Thus, this study explored the effect of demographic variables, the amount of smartphone usage, type of smartphone use and psychosocial variables on smartphone dependence of the elder group. We analyzed the data of 5627 (50s and 60s) of the Internet overdependence survey data of the Korea Information Society Agency in 2016. As a result of hierarchical multiple regression analysis, More frequency of smartphone use of weekday and weekend, and usage time of smartphone of weekday were related to greater smartphone dependence. More smartphone use for information seeking and games were associated with greater smartphone dependence. And, as loneliness and anxiety increased, smartphone dependence increased, while smartphone dependence decreased, as social capital increased. Through this study, it is necessary to understand characteristics related to smartphone dependence of elder and older group, and to use this knowledge to solve their smartphone dependence. Future studies also need to identify the causal relationship between predictors of smartphone dependence in elderly and older people.

스마트폰의 확산과 그에 따른 카카오톡의 괄목할 열풍과 발맞추어 대학생들의 카카오톡 사용 현황에 대한 조사를 실시한다. 본 연구에서는 카카오톡 사용에 대한 양적인 조사를 연구 범위로 하고 조사방법론으로는 대전의 한 대학교의 학생들에게 설문을 통하여 카카오톡의 사용시간을 파악하는 설문방법을 취한다. 먼저 성별과 학년별 스마트폰 종류의 차이가 있는지를 분석하고, 카카오톡 사용시간에 있어 스마트폰 종류, 성별에 따른 차이와 학년에 따른 차이를 SPSS 20 통계패키지를 이용하여 검증한다. 검증결과는 성별과 학년별로 스마트폰의 종류는 차이가 없음이 나타났다. 또한 스마트폰 종류별로도 사용시간에 차이가 없었다. 하지만 성별 스마트폰 사용시간은 통계적으로 유의한 차이가 있었으나 학년별로는 유의한 차이가 없었다.

스마트폰의 이용자가 최근 급증하고 있다. 그에 반응하듯 많은 기업들은 기존의 서비스 외에도 스마트폰을 이용해 사용할 수 있는 서비스들을 시작하고 있고, 기존의 모바일로 불가능했던 작업들을 장소와 시간에 구애받지 않고 가능케 되었다. 이처럼 스마트폰의 이용인구가 급격히 증가하고 관련 컨텐츠들이 봇물 쏟아지듯 넘쳐나면서 개인정보 유출이나 악성코드로 인한 보안 사고도 급격히 늘고 있다. 본 논문에서는 스마트폰에 악영향을 미치는 악성코드에 대해 간단히 살펴보고, 악성코드가 쉽게 보안체계를 무너뜨릴 수 있게 만드는 스마트폰의 보안 위협요소 대하여 알아본다. 또 현재 사용되고 있는 대응 방안은 무엇이 있는지, 그리고 향후에 이러한 악성코드들과 위협요소를 줄이는 방법, 또는 대응 전략에 대하여 연구하였다. 이러한 연구는 스마트폰 보안 사고를 줄이거나 사전에 예방하고, 더 나은 스마트폰 사용 환경을 제공할 것이다.

Recently mobile application providers and telecommunication companies went through a difficult time in a highly competitive mobile and its application market where we've seen a huge trend for diverse mobile applications occurring on smart phone. If there were a time when those of companies need to analyze factors affecting users' intention to download or recommend others applications more than ever, it is now. Based on UTAUT model, this research is to provide them with strategic implications by analyzing those factors according to application types with utilization and hedonic values. As a result, firstly trust and personalization have positive impact on Performance Expectancy and users' intention to use have been significantly affected by Performance Expectancy and Effort Expectancy. Secondly the result of path analysis has a different outcome according to application types with utilization and hedonic values. Therefore it is expected that the research gives practical and strategic implication for application developer, mobile companies and others helping application development, new service launch and marketing implementation.
