본 연구에서는 유아의 스마트폰 과의존 유형을 파악하고 과의존의 차이를 분석하고자 하였다. 이를 위해 2019년 스마트폰 과의존실태조사에서 자료 중 유아 992명을 대상으로 분석하였다. 전체 유아 중 고위험군 1.9%, 잠재적위험군 19.2%, 일반사용자군 78.9%로 나타났다. 스마트폰 과의존 유형에 따른 과의존의 하위 변인인 조절실패, 현저성, 문제적 결과가 차이가 있는 것으로 확인되었다. 이러한 결과는 유아들이 스마트폰 이용이 증가하고 있는 시점에서 유아의 올바른 스마트폰 사용을 위한 교육과 과의존에 관한 예방 방안이 필요함을 시사해 준다는 점에서 본 연구의 의의를 찾을 수 있다. 또한 유아교육현장에서 유아가 건강한 성장을 도모할 수 있도록 과의존 예방을 위한 가정환경 점검 및 부모교육에 관한 기초적인 연구 자료가 될 수 있을 것으로 기대된다.

The purpose of this study was to investigate the identified groups depend on the relationship of smartphone overdependence and adolescents' perception of smartphone overdependence itself. The study also explored gender positions in classified groups and the relationship between irrational perception of smartphone and positive emotion while smartphone usage. The participants to the study were 2,033 adolescents, aged between 10 and 19 from a smartphone overdependence survey of the National Information Society Agency. As a result of the qui-square analysis and MANOVA, four groups were classified depend on perception of smartphone overdependence and related smartphone overdependence behaviors. Second, gender did not show any differences in groups. Third, adolescents with lower perception in smartphone overdependence showed lower perception of smartphone usage compared to other adolescents in three groups. Fourth, adolescents with constructive perception in smartphone overdependence reported positive emotions. The results of this study suggest that it is necessary to understand adolescents' smartphone overdependence and look together with the irrational perception of smartphone.

Internet overdependence has become a public health concern in Korea. It is well known that family and community level efforts could alleviate possible harms from Internet use. However, little research exists regarding smartphone overdependence. This study examines factors affecting smartphone overdependence and, specifically, help-seeking for smartphone overdependence among Korean adolescents. The study is based on parental mediation theory and uses a help-seeking framework. The results indicate that preventative education provided by school and community increases the levels of awareness of both the possible harms from smartphone use and the option of accessing the mental health service, while it was not effective in preventing smartphone overdependence. Parental mediation was a protective factor for smartphone overdependence but was negatively associated with the intention to use the mental health service. In sum, behavioral problems related to smartphone use require multidimensional preventative efforts from both the family and the community. It is suggested that effective preventive education methods are developed for parents and adolescents.

의존 문법을 사용한 의존 파싱에서 기본적인 단어(품사정보)들 사이의 의존 관계 검사에 의한 파싱 방법은 불필요한 의존 관계의 생성을 가져온다. 이러한 과생성을 해결하기 위하여 파싱 단계에서 보다 정교한 의존 파싱을 통해서 불필요한 의존 관계의 생성을 최소한으로 줄이는 방법에 대한 연구가 필요하다. 본 논문은 의존 파싱에서 최소한의 의존 관계를 생성하기 위하여 후보 의존소가 지배가능경로 상에서 술어 지배소와의 의존 관계 검사 시에 술어의 하위범주화 정보를 이용하는 효율적인 의존 파싱 방법을 제안한다. 이것은 의존 파싱의 다음 처리 단계인 의존 제약의 적용에 훨씬 부담을 덜어 줄 수 있다.

This study examined the effects of smartphone usage types and excessive expectation for smartphone on adolescents' smartphone overdependence. It utilized the data of 3,454 adolescents (1,758 males and 1,696 females), aged between 13 and 19 from a smartphone overdependence survey of the National Information Society Agency. As a result of the hierarchical multiple regression analysis, age and household income had a negative effect on smartphone overdependence. Weekly smartphone usage time positively affected the serious consequences (sub-factor of smartphone overdependence). Among the different types of smartphone usage, information seeking, SNS, gaming, and the excessive expectation for smartphones had positive impact on smartphone overdependence. Smartphone usage for leisure seeking did not affect smartphone overdependence, but it negatively influenced serious consequences. Messenger use did not affect smartphone overdependence, but the use had a positive effect on salience, and a negative effect on serious consequences. The results of this study suggest that it is necessary to identify the types of smartphone use as well as the usage time to understand the smartphone dependence of adolescents. In addition, it seems necessary to recognize and correct the irrational excessive expectation for smartphone in order to prevent dependence and implement effective interventions.

Purpose of this study is to analyze the correlation between the level of smartphone overdependence and depression among the high school student. Study subjects were 50 high school student. The assessment of the level of smartphone overdependence was used by the smartphone overdependence scale for adolescents and the assessment of the level of depression was used by Korean ver. of patient health questionnaire-9. As the results, the positive correlation was showed between the level of smartphone overdependence and depression and the statistically significant difference was showed. It was found that the higher the level of smartphone overdependence among high school students, the higher the level of depression. The smartphone overdependence among high school students could contribute to increase the level of depression. Thus, based on these results of this study, it is necessary to consider to reduce the level of smartphone overdependence and depression among high school students and subsequent studies should be conducted to clarify the casual relationship and influences of the level of smartphone overdependence and depression among high school students.

본 연구는 한국지능정보사회진흥원에서 제공한 2018년 스마트폰 과의존 실태조사에서 사용된 11개 변수와 스마트폰 과의존과의 관계를 탐색하고, 이를 통해 딥러닝 기반 스마트폰 과의존 분류 분석 모델을 개발하고자 시행되었다. 학습데이터셋은 전국 10,000개 가구내 만 3-69세 스마트폰 이용자 25,465명의 스마트폰 이용 형태 및 개인적 특성에 관한 데이터이다. 딥러닝은 심층신경망(DNN)을 설계하였으며, 은닉층(hidden layer)은 4개층으로 구성하였다. 입력한 데이터는 각각 200개, 150개, 100개, 50개, 2개 노드를 거치면서 최종 출력 정보인 스마트폰 과의존 분류율로 나타나는 모델이다. 이때 스마트폰 과의존 분류률을 높이기 위해 학습률(learning rate)과 같은 하이퍼 파라미터를 활용하여 세부조정하면서 가장 잘 학습하는 값을 찾아내었다. 연구결과, 학습횟수가 300번으로 학습율(learning.rate)이 0.01일때 훈련데이터에서 97.43%, 검증데이터에서 98.06%로 가장 높게 나타났다.

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.

This study was proposed to examine the mediating effect of basic psychological needs on how parenting attitude affect middle school students with over-dependence on smart phone. This study utilized 2017 survey research by National Information Society Agency (NIA), namely a long-term follow-up study of 901 people with over-dependence on internet and smart phone. This study showed two findings. First, over-dependence on smart phone had correlations with basic psychological needs- autonomy(r=-.22, p<.001) and competence(r=-.13, p<.001); with parenting attitude- positive parenting(r=-.21, p<.001) and negative parenting(r=.15, p<.001). Second, both parenting attitude and basic psychological needs had a causal relationship with over-dependence on smart phone. These results can provide a basis to reconsider social awareness on over-dependence on smart phone among middle school students. This study proposed few research directions for further study to prevent over-dependence on smart phone and to educate parents.
