This study investigated the antecedents and the performance impact of two types of Smartphone functions (communication vs. computing functions) in organizational environment and the moderating impact of Smartphone users' organizational roles. More specifically, identifying two distinct types of Smartphone functions such as communication functions and computing functions (including informational, social network, and resource management functions), we investigated the impact of three antecedents (Smartphone dependency, task mobility, and perceived critical mass) on the use of the two Smartphone functions and how organizational workers' perceived performance gains differ by using these two different Smartphone functions for their workplace activities. We tested our hypotheses with survey data collected from 176 organizational workers. Our findings suggest that Smartphone dependency, task mobility and perceived critical mass of Smartphone use are significantly associated with the use of the two different functions, and that the use of computing functions is more strongly associated with perceived performance gain than the use of communication functions. We also found that managerial roles played by individual workers differently moderate the impact of Smartphone use on perceived performance gain. The present findings enable researchers and practitioners to better understand the impact of Smartphone use in workplaces.

본 연구는 간호대학생들의 공감능력, 자기조절력, 스마트폰 의존성이 대인관계에 미치는 영향을 파악하기 위한 서술적 조사연구이다. 연구 자료는 A시 S대학교에 재학 중인 간호대학생 157명을 대상으로 구조화된 설문지로 조사하였다. 자료수집 기간은 2019년 5월 27일에서 5월 31일까지이며, 수집된 자료는 SPSS WIN 14.0을 이용하여 Independent t-test, One-way ANOVA, Pearson correlation coefficients, Stepwise multiple regression으로 분석하였다. 연구결과, 대상자의 성적에 따라 자기조절력(F=5.319, p=.006)과 스마트폰 의존성(F=4.854, p=.009) 정도의 차이가 나타났고, 스마트폰 사용시간에 따라 스마트폰 의존성(t=-3.381, p<.001) 차이가 있었다. 연령은 자기조절력과 순상관관계(r=.194, p=.015)를, 스마트폰 의존성과는 역상관관계(r=-.223, p=.005)를 보였다. 또한 자기조절력은 공감능력(r=.244, p<.01)과 대인관계(r=.540, p<.001)와는 순상관관계를 보였으며 스마트폰 의존성(r=-.432, p<.001)과는 역상관관계를 보였다. 공감능력과 대인관계는 순상관관계(r=.476, p<.001)에 있었다. 회귀분석 결과, 대인관계에 영향을 주는 요인은 자기조절력(β=.477, p<.001), 공감능력(β=.359, p<.001), 스마트폰 사용시간(β=.208, p<.01)이었으며, 총 설명력은 45.0%(F=12.029, p<.01)이었다. 본 연구를 통해 간호대학생의 대인관계를 향상하기 위한 프로그램에서는 자기조절력, 공감능력, 스마트폰 사용시간에 대한 고려가 필요할 것으로 사료된다.

The purpose of this study was to investigate the effect of mother's smartphone dependency and maternal guilty feelings on early childhood emotion regulation. The subjects were 326 mothers of 2 to 5 year olds. Mothers' smartphone dependency was assessed by the Korea Agency for Digital Opportunity & Promotion(2006), guilty feelings by the Maternal Guilt Scale(Sung 2011), and early childhood emotion regulation assessed by the ERC(Park 2012). The results of the study were as follows. First, mother's dependency on smartphones was highly related with early childhood emotion regulation. Maternal guilty feelingswere weakly related with child's emotion regulation. Relationship between mother's dependency on smartphones and maternal guilty feelingswasmoderate. Second, mother's positive expectations towardssmartphones and maternal guilty feelings from negative parenting behavior explained early childhood emotion regulation as much as 69%.

This study examined the effects of negative parenting attitudes on adolescents' academic helplessness through the mediating effects of social withdrawal and smartphone dependency. Data from the panel study of Korean Children and Youth Panel Survey 2018 (KCYPS 2018) collected by the National Youth Policy Institute (NYPI) was used to examine the research model. The subjects of the study consisted of 2,541 first grade middle school students (1,375 boys and 1,166 girls). Confirmatory factor analysis [CFA], structural equation modeling [SEM], and bootstrapping analysis were conducted by means of SPSS 25.0, AMOS 25.0, and Hayes's PROCESS programs to examine the serial multiple mediating effects. The study results were as follows. First, negative parenting attitude had a direct effect on adolescents' academic helplessness. This implies that adolescents who perceive their parents' attitudes to be high in coercive, rejective, and chaotic levels indicate that they can easily get exhausted in academic settings. Second, negative parenting attitudes had an indirect effect on adolescents' academic helplessness through social withdrawal and smartphone dependency. The results suggest that a high level of negative parenting attitude leads to higher social withdrawal and smartphone dependency that influences adolescents' academic helplessness.

본 연구의 목적은 융복합시대에서 청소년들이 지각하는 부모의 긍정적양육태도와 부정적양육태도가 청소년의 스마트폰 의존도에 미치는 영향과 그 과정에 있어서 또래애착의 매개효과를 검증하는데 있다. 이를 위해 한국아동 청소년패널 초4 패널 6차년도 데이터를 이용하였으며 본 연구에 적합한 1,823명의 청소년을 대상으로 부모의 양육태도, 또래애착 및 청소년의 스마트폰 의존도에 대한 경로분석 모형을 살펴보았다. 주요 분석결과는 다음과 같다. 첫째, 부모의 긍정적 부정적양육태도가 청소년의 또래애착에 영향을 미치는 것으로 확인되었다. 둘째, 부모의 긍정적 부정적양육태도가 청소년의 스마트폰 의존도에 영향을 미치는 것으로 확인되었다. 셋째, 부모의 긍정적 부정적 양육태도가 청소년의 스마트폰 의존도에 미치는 직접적인 영향과 또래애착을 매개로 하는 간접적인 영향이 확인되었다.

스마트폰 가속도 센서를 이용한 사용자 행위 인식은 동일한 행위를 수행하더라도 사용자마다 가속도 데이터 패턴이 서로 달라지는 사용자 의존성 문제를 가지고 있다. 그뿐만 아니라 스마트폰은 사용자의 어느 주머니나 손에도 놓일 수 있기 때문에 위치 의존성 문제도 지니고 있다. 본 논문에서는 특정 사용자나 특정 폰 위치에 대한 의존성이 적은 효과적인 행위 인식 방법을 제안한다. 제안한 방법을 기초로 안드로이드 스마트폰에서 동작하는 실시간 행위 인식 시스템을 구현하였다. 서로 다른 사용자와 서로 다른 폰 위치로부터 수집한 총 6642개의 샘플들을 이용한 실험을 통해, 본 논문에서 제안한 행위 인식 시스템의 성능을 분석하였다.

Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

The smartphone is a necessary communication and productivity tool. Unlike other neutral, utilitarian technologies, smartphones are also a social display of wealth, i.e., of conspicuous consumption. Behavior around necessity and conspicuous goods are normally separate research tracks, and we can find no studies for technology products that exhibit both traits. We therefore propose a four-factor model that explains conspicuous consumption of "necessary" smartphones: dependency, social influence, the need for social connection, and convenience, in the United States, Mexico, and the Philippines. This paper provides confirmatory support for extant literature of the four constructs; it demonstrates the viability of the survey instrument across countries; and it shows similar effects among country models. Our structural model results imply the borderless nature of smartphone conspicuous consumption.

IoT technology application has been part of modern people's everyday life. This technology makes people to depend on smart devices. 'Smartphone' is the most typical example. Despite the advantages given by this device, the bad side effects are also notable. This paper presents interactive content on the dependence of smartphone device. The research objective is to make individuals to reduce the use of smartphones by realizing their own problems of smartphone dependency. Research was progressed by analyzing aspects obtained from users participating in the self-developed interactive game contents. As a result of the analysis, approximately 68% of people were aware of the problem through this content. This indicates the potential of using convergence research in interactive contents with other fields furthermore.
