The purpose of this study is to examine the effects of parental abuse and neglect on adolescents' internet addiction, and to verify the mediating effect of subjective happiness in the relationship between parental abuse and neglects and adolescent internet addiction. To this end, dat from the 16th year of the 2021 Korea Welfare Panel(KWPS) conducted by the Korea Institute for Health and Social Affairs were used. In this study, 1st, 2nd and 3rd graders of high school were analyzed, and data from a total of 325 students were analyzed. The analysis utilized SPSS 27.0 and Hayes(2013)'s Macro Process(model 4) to verity correlation analysis and mediating effects between related variables. The results of the analysis are as follows: First, abuse and neglect from parents directly affect adolescents' Internet addiction. Second, it was analyzed that subjective happiness mediated the effect of parental abuse and neglect on adolescents' Internet addiction.

This study was conducted to verify the mediating effect of ego-resilience when early childhood teachers' autonomy affects teacher efficacy. The subjects of the study were 316 early childhood teachers in J degree. For data analysis, SPSS 25.0 was used to conduct Baron & Kenny's 3-step mediation effect analysis using descriptive statistics, Pearson's correlation analysis, and Process Macro. As a result of the study, first, early childhood teachers' autonomy, teaching efficacy, and ego-resilience were found to have a positive correlation with each other. Second, when early childhood teachers' autonomy affects teacher efficacy, it was found that ego-resilience partially mediates. In other words, it can be interpreted that the autonomy of early childhood teachers has a meaningful effect when ego-resilience is added when it affects the improvement of teacher efficacy. Through this, it is intended to provide basic data for improving early childhood teachers' sense of teacher efficacy and preparing a direction for teacher education support.

As the employment situation has become increasingly severe in recent years, the employment pressure has become intense. How to improve the employability of university students has become the focus of public attention. This study aims to investigate that hope moderates the mediating role of entrepreneurship education in the relationship between career exploration and employability. The purposive sampling method was applied to the sampling of the survey subjects from Guangdong Province, China. A total of 346 questionnaires on career exploration, hope, entrepreneurship education and employability were collected and analyzed. The collected data was analyzed using SPSS PC+ Mac ver. 26.0 and SPSS PROCESS macro ver. 4.2. The statistical methods applied were frequency analysis, corelation analysis, and moderated mediation effect analysis. The conclusion of the study is as follows. First, career exploration had a significant positive correlation with entrepreneurship education, hope and employability. Second, hope showed the moderated mediation effect on the mediating role of entrepreneurship education in the relationship between career exploration and employability. This study suggesed a plan to utilize career exploration, entrepreneurship education and hope to increase college students' employability.

This paper proposes an approach to analyzing the relationship between technology and services, and to identifying promising service areas for technology-based firms with the analysis of business model (BM) patents. First, BM patents and technology patents are collected and classified into their relevant categories, respectively. Second, patent citation analysis is conducted to analyze the linkage and impacts between each technology and service field at macro level. Third, as a micro level analysis, patent co-classification analysis is employed to identify the interrelationships among specific technology and service areas. Finally, the promising service areas for technology-based firms seeking service areas for diversification is investigated with portfolio analysis. The working of the proposed approach is provided with the help of a case study of IT and mobile services. The proposed approach could guide and help managers of technology-based firms to discover the opportunity of the diversification to new areas in emerging service fields.

Two-dimensional mesoscopic analysis (meso-analysis) is applied to solids including microdefects such as microcracks or holes. For the problem of effective moduli of microdefrcted solids, various approximate schemes are introduced by using microcrack density and hole density for macro level parameter. Also, microcracks distributed in the parallel direction and random direction are considered. Several numerical studies using meso-analysis are carried out and the results are compared with several approximate schemes in order to show the validity of proposed meso-analysis.

In this study, out-of-plane properties and CTEs were predicted for 8-harness satin weave textile composites. The properties were calculated by unit cell analysis for configurations with varied waviness ratio and phase shifts. Macro elements were employed to reduce the computer resource requirement. It was found that the out-of-plane properties and CTEs were varied as the phase shift changed. However the dependency was much weaker than the in-plane properties.

본 논문에서는 비상운전 상황하에서 표출되는 운전원들의 직무전략 및 인지적인 특성을 도출하기 위해 운전원 교육 프로그램을 대상으로 운전원들의 직무특성을 분석하였다. 운전원들의 직무특성을 인지과정의 개입 정도에 따라 크게 Macro와 Micro로 구분하여 이들 직무특성을 잘 대변해 줄 수 있는 비상운전 시나리오를 개발하였다. 시뮬레이터를 통해 개발 시나리오에 따른 운전원들의 비상운전절차 수행과정을 비디오로 기록, 운전원들의 행동과 대화내용을 전산 분석하여 직무특성을 도출하였다.

The response of a 1:5 scale 3-story masonry-infilled RC frame which was designed only for gravity loads were simulated by using a nonlinear analysis program, RUAUMOKO 2D. The objective of this study is to understand behavior of masonry-infilled panel and to verify the correlation between the experimental and analytical responses of a masonry-infilled RC frame. It is concluded from this comparison that the strength, stiffness and local behavior of the structure can be predicted with some reliability using this macro-model.

Recent interests in intelligent LP modeling aim to support MS/OR-naive users to be able to apply LP models to practical problems without the expert knowledges required. For more generalized LP modeling, a GPS(General Problem Solver)-based approach is suggested in this paper. It identifies modeling process as a means-ends analysis process. In view of this approach, a) we first divide the knowledges into domain specific assertive knowledges(state) and procedural knowledges about LP modeling(operator and macro) for model-domain independence, b) and then generate LP model according to the difference resolution techniques.
