Despite the ever-increasing smartphone addiction of adolescents and a variety of consequent problems not much research has been conducted on the issue. It is time to prepare a set of countermeasures to protect them from the addiction. The central purpose of the current paper is to identify how use motives, self-control and social withdrawal affect their smartphone addiction. It was found (i) that the motives of information acquisition, social relationship, amusement and use of leisure time exert significant influence on smartphone addiction, (ii) that less self-control and greater impulsiveness result in greater addiction, and (iii) that social withdrawal of users also have significant effect on smartphone addiction. Such findings are expected to provide base data for any attempt to develop countermeasures against addiction. It is desirable that we had better check the play activities of adolescents and develop self-control programs to help them alleviate impulsiveness than simply impose strict restrictions on the use of smartphones.

The factors affecting smart phone addiction were record, tolerance, abstinence, difficulty of daily living, and aim for virtual world which accounted for 88.2%. Also factors affecting addiction were entertainment/leisure, flaunt/trend which accounted for 12.9%. In conclusion, smart phone use motivations was correlated positively with addiction, while addiction was correlated negatively with self-control. Therefore more positive and desirable ways of smart phone use, and plans for improvement of self-control should be studied.

The effect of smartphone usage motivation on application display advertising attitude and advertising avoidance was investigated. In addition, the mediating effect of advertising intrusion was confirmed. The total number of participants in the study was 309, and the data collection method used a survey method. Covariate structural analysis was conducted to investigate the causal relationship between smartphone usage motivation and advertising attitude and the mediating effect of perceived intrusion on advertising avoidance. There are five results. First, the motivation for using smartphones had a significant effect on the display advertising attitude of smartphone applications. Second, the display advertising attitude of the smartphone application had a significant effect on the advertising avoidance behavior. Third, the display advertising attitude of smart phone application had a significant effect on perceived advertising intrusion. Fourth, the perception of intrusiveness of display advertising in smartphone applications had a significant effect on advertising avoidance behavior. Finally, it was confirmed that the perceived ad intrusion has a partial mediating effect in the causal relationship of the smartphone application display advertising attitude to the ad avoidance behavior. The results of this study will contribute to suggesting strategies to reduce advertising avoidance behavior.

This study were investigated to the factors affecting smart phone applications to avoid display ads. The results of this study are as follows. First, factor analysis, propensity for advertising intrusion was the result of a single factor. Also showed significant effect advertising intrusion ad avoidance tendency. Second, the smartphone motivation for the use of the results of factor analysis, seven factors were, Entertainment, information acquisition, learning/work use, multimedia use, ease of life, time leverage, respectively. Showed low levels of advertising avoidance learning/working synchronous usability and ease high motivation life. Finally a smart phone for involvement that there is no significant difference in advertising intrusion tendency appeared. High involvement group was obtaining information, entertainment, social relationships, and multimedia use, ease of living, time management motivation significantly higher than the low involvement group. The results of this study it is expected that the smartphone application smartphone users to reduce evasion of advertising practitioners to give answers to create display ads advertising.

This study aimed to investigate the effects of motive of use, stress and interpersonal satisfaction on smartphone overdependence in dental hygiene undergraduates. A questionnaire survey was conducted on 216 dental hygiene students in colleges in Dajeon and Chungnam regions. The results showed that motive of use(3-4hours/>4hours)(${\beta}=-0.178$), weekday usage (<3hours/3-4hours)(${\beta}=0.163$), and weekday usage (${\beta}=0.196$) had a high impact on smartphone overdependence in dental hygiene students. Weekday usage dummy 1 was the factor with the greatest impact, with an explanatory power of 25.6%. Additional studies on various factors that affect smartphone overdependence as well as education programs for preventing smartphone overdependence in dental hygiene students are needed.

The synchronization feature on the smartphone by default (default) value is set. Smartphone synchronization has been set is stored that smartphone data is automatically backed up is stored When connected to a PC with a smartphone dedicated cable. The backup data is a common technique to analyze the content to be difficult to apply forensic techniques can find out information on criminal suspects. In this paper, the backup data is synchronized to the smartphone through forensic analysis is the study of forensic evidence. In a lab environment to send personal financial information on smartphone, smartphone is assumed that the experiment is compromised. Smartphone's backup data by using the forensic tools in crime associated with personal financial information and analyze data. And, to be adopted by the court will study the evidence leveraging forensic technology. Through this paper as a basis for smartphone forensic analysis will be utilized.

디지털 컨텐츠는 UHD, 3D, 파노라마 영상 등 다양한 형태로 발전되고 있다. 그 중 파노라마 영상은 여러 영상을 정합하여 넓은 시야각을 제공하는 컨텐츠로 전문적인 기술자들을 중심으로 제작되고 있다. 또한 디지털 컨텐츠의 제작자는 전문가에서 일반인으로까지 범위가 확장되었고, 발전된 형태의 컨텐츠를 일반인이 스마트폰 등의 개인 단말로 손쉽게 제작할 수 있도록 해주는 컨텐츠 생성 기술이 발달되고 있다. 이에 본 논문에서는 일반 사용자들이 각각의 스마트폰 단말로 촬영한 여러 동영상들을 하나의 파노라마 영상으로 제작하기위한 기술 중, 각기 다른 스마트폰의 시간축을 이미지 매칭을 통해 하나의 통일된 시간축으로 동기화 시키는 기법에 관하여 연구하였다. 이를 위해, 본 논문에서는 동영상에서 시간정보로 이용하기 위한 오브젝트의 움직임이 포함된 시퀀스를 찾는 방법과 해당 시퀀스를 이용하여 다른 동영상과의 이미지 매칭으로 시간축을 동기화 시키는 방법을 제안한다.
