본 논문은 일본어 웹 문서 말뭉치로부터 의존 구문 구조 관점으로 바라본 단어들의 동시발생(co-occurrence) 정보를 사용하여 서브토픽 마이닝(subtopic mining)을 수행하는 방법론을 제안한다. 우리는 의존 구문 구조를 반영하는 간단한 패턴들을 사용하여 서브토픽들을 추출 및 생성하고, 제안한 수식을 바탕으로 순위화한다. 본 방법론은 기존의 주요 상용 검색 서비스에서 제공하는 연관 검색어 및 추천 검색어를 사용한 방법론보다 좋은 성능을 보였다.

컴포넌트기반 소프트웨어의 신뢰도를 높이기 위해서 개별 컴포넌트의 데스팅과 더블이 통합된 컴포넌트들이 올바르게 동작하는지 테스팅할 필요가 있다. 이 논문에서는 컴포넌트기반 소프트웨어에서 컴포넌트의 구성과 통신에 관한 정보를 얻기 위해 아키텍쳐 기술에서 제어 의존성과 자료 요소를 식별하여 테스트 모델을 구축한다. 구축한 테스트 모델에서 테스트의 단위가 되는 OFU(Observable functional Unit)을 식별하고 자료 의존성을 이용하여 OFU의 수행 순서를 결정한다.

소프트웨어 품질 향상과 생산성 향상이라는 측면에서 소프트웨어 재사용의 중요성이 널리 인식되어지고 그에 따른 재사용 컴포넌트에 대한 관심이 나날이 커져가고 있다. 이에 따라 재사용성을 측정하는 방법에 대한 연구의 중요성이 커지고 있다. 본 논문에서는 기존의 결합도를 측정하는 방법을 변형하여 두 클래스간의 의존 정도를 측정하고 클래스를 노드로, 측정한 의존 정도를 예지 값으로 하는 방향 그래프를 그린다. 그리고 그 그래프를 클러스터링을 하여 재사용 컴포넌트의 후보를 추출하는 방법을 제시한다.

This study was conducted to investigate the mediating effect of academic stress on the relationship between smartphone overdependence and the communication competence of nursing students. The research subjects were nursing students in cities A and Y. The research period was from March 2 to March 9, 2023, and the number of subjects analyzed was 139. Descriptive statistics, Pearson correlation were analyzed using SPSS/WIN 26.0, Process macro program the collected data. The results of the mediating effect of academic stress on the relationship between smartphone dependence and communication competence showed that academic stress (β=.226, p=.005) mediated the effect on the relationship between smartphone dependence and communication competence(Z=-3.131, p=.002). As a result, the combined explanatory power of the variables on nursing student's communication competence was 15.4%. In addition, in order to reduce nursing students' smartphone overdependence, it is necessary to educate them about smartphone use and develop self-control, provide interventions to cope with academic stress, and develop intervention programs to improve communication competence.

This study examined an effect of mother's smart device overdependence and short-term longitudinal mediation effect of mother's responsiveness on children's overindulgence tendency in smart devices. A total 144 children-mother dyads(male 73, female 71) participated in the study. The results of path analysis were as follows. The mother's smart phone overdependence and children's overindulgence tendency in smart devices were measured at time 1 and mother's responsiveness and children's overindulgence tendency were measured at time 2, six months later. When Time 1 children's overindulgence tendency in smart devices was controlled, Time 1 mother's smart phone overdependence significantly predicted time 2 children's overindulgence tendency. This study suggested empirical findings that caregiver's smart device were related with children's overindulgence tendency.

The purpose of this study is to find out whether smartphone overdependence serves as a significant mediating effect in the relationship of anxiety and school life adjustment to prevent and reduce problems of anxiety and smartphone overdependence among university students and to seek alternatives to improve school life adjustment. For this purpose, a structural equation model analysis was conducted on male and female university students attending a four-year university located in Gwangju Metropolitan City to verify the mediated effect. As the result of the analysis, The mediating effects of smartphone overdependence were statistically significant and presented as a partial medium, showing the direct effect of anxiety directly affecting school life adjustment and the indirect effect of anxiety on school life adjustment by means of smartphone overdependence. Based on these findings, the significance of the study and its implications were discussed, and suggestions were put forward for further study.

This study looked at how children's mental health is affected by Domestic violence and school violence at home and school after Covid-19, as well as how these victim experiences relate to children's mental health. This study surveyed 650 students from 14 middle schools in Wanju, Korea. The moderating effect of smartphone overdependence in the experience of violence and mental health was investigated. Major research findings: First, children's exposure to domestic violence and school violence has a significant impact on smartphone dependence. Second, children's exposure to domestic and school violence has a significant impact on their mental health. Third, it has been demonstrated that smartphone dependence is statistically significant in the relationship between domestic and school violence. Based on these findings, we present a convergent intervention and practice strategy for children in the Covid-19 era to cope with mental health problems and expand the support system.

The purpose of this study was to identify the self-awareness of smartphone dependence among undergraduate students and their response to the same. The data was drawn from a survey on smartphone overdependence conducted by the Ministry of Science and information and communications technology (ICT) and the National Information Society Agency in 2017. The responses of 1,735 undergraduate students were analyzed by frequency, percentage, mean, standard deviation, minimum-maximum value, ��2-test, independent t-test, Pearson's correlation coefficient, and stepwise multiple regression analysis. The results indicated that 22.3% of participants were at risk of smartphone dependence, and 63.6% of them were unaware of their dependence on smartphones. The perception of smartphone dependence was significantly associated with a higher risk of smartphone dependence (��=.35, p=.000) and the increasing use of applications such as games (��=.19, p=.000), television/video (��=.11, p=.000), and learning (��=.11, p=.000). Of the participants with dependence awareness, only a few knew about the existence of centers to prevent smartphone and internet dependence. Moreover, they rarely utilized these centers. However, the participants felt the need for more counseling agencies (26.8%), programs for dealing with oneself (23.2%), information about smartphone dependence (14.9%), and help to overcome dependence (10.9%). These findings show the need to establish public services so that students can easily access correct information on smartphone dependence and address this problem.
