This study was planned to develop an Internet Game Addiction Scale for 9- to 12-year-old Korean children. Based on literature review and analysis of counseling cases, the concept of the internet game addiction was defined. Items of the scale were developed and then the content validity of the scale was examined by 20 professionals. Then a preliminary survey of 188 3rd to 6th grade students was made, and the main survey of 699 3rd to 6th grade students throughout Korea. The main results are as follows; [I] Internet Game Addiction Scale consists of 3 factors with 20 items : game-oriented life(6 items), tolerance & mastery loss(7 items), and withdrawal & emotional experience(7 items); [II] appropriateness of item mean and standard deviation was proved, a 3-factor structure confirmed through factorial analysis and cross validation; [III] appropriateness of the scale confirmed through criterion validity and reliability.

This study attempted to develop a valid and reliable instrument capable of measuring Korea midlife family resilience (The Korea Midlife Family Resilience Scale: KMFRS). An exploratory, non-experimental, cross-sectional, and quantitative design was used to develop and validate the KMFRS. A tentative factor structure of family resilience and an item pool of the scale were constructed through a comprehensive literature review and personal interview. The pilot study was conducted with 424 middle aged adults(40~59) to select items for a scale, resulting in a preliminary scale composed of 70 items. In the main study, the preliminary scale was administered to a national representative sample of 562 middle-aged Korean adults. The scale was filtered into 40 items by the item analysis and an exploratory factor analysis, resulting in 6 factors: Family Connectedness & Problem Solving, Family's Positive Perception of Adversity, Family's Economic Stability, Family Religion & Spirituality, Support of Extended Family, and Support of Friends & Neighbors. These 6 factors explained 61.82% of total variance. The findings of the current study indicate substantial support for the reliability and the validity of the KMFRS. Other challenges and suggestions for future research on family resilience scale are discussed.

Thermalhydraulic reactor simulation of tomorrow will require a new generation of codes combining at least three scales, the CFD scale in open medium, the component scale and the system scale. DNS will be used as a support for modelling more macroscopic models. NEPTUNE is such a new generation multi-scale platform developed jointly by CEA-DEN and EDF-R&D and also supported by IRSN and FRAMATOME-ANP. The major steps towards the next generation lie in new physical models and improved numerical methods. This paper presents the advances obtained so far in physical modelling for each scale. Macroscopic models of system and component scales include multi-field modelling, transport of interfacial area, and turbulence modelling. Two-phase CFD or CMFD was first applied to boiling bubbly flow for departure from nucleate boiling investigations and to stratified flow for pressurised thermal shock investigations. The main challenges of the project are presented, some selected results are shown for each scale, and the perspectives for future are also drawn. Direct Numerical Simulation tools with Interface Tracking Techniques are also developed for even smaller scale investigations leading to a better understanding of basic physical processes and allowing the development of closure relations for macroscopic and CFD models.

The purpose of this study was to develop the Resilience Scale for Children(RSC) and to evaluate its reliability and validity. The RSC was administered to 482 children in grades 4 through 6. Factor analysis of the 30 item scale demonstrated Cronbach's ${\alpha}=.89$ for internal consistency of total items. The results of the confirmatory factor analysis supported a five-factor structure. Retest stability was acceptable for the five-factors. Tests of the present scale for criterion-related validity compared favorably with Self-Perception Profile for Children (Lee, et al., 1992) and the Stress Coping Behavior Scale for Children (Kim and Kang, 2003) confirming its applicability to elementary school students for assessment of resilience.

본 연구의 목적은 한국판 자기자비 척도(Korean self-compassion scale)의 신뢰도와 타당도를 검증하기 위해 교정기관 종사자들을 대상으로 수집된 자료와 관련된 척도들 간 관계를 알아보는 것이다. 자기자비척도의 타당화를 위해 312부의 설문지가 최종분석에 포함되었으며, 상관분석, 탐색적-확인적 요인분석을 실시하였다. 관련 척도와 신뢰도를 알아보기 위해 한국인 직무스트레스 척도(Korean occupational stress scale), 우울척도(The center for epidemiological studies depression scale), 소진척도(Maslach burnout inventory scale), 스트레스 지각척도(perceived stress scale), 삶의 만족도 척도(satisfaction with life scale)를 사용하였다. 탐색적 요인분석결과 자기자비척도는 자기친절, 자기비난, 보편적 인간성, 고립, 마음챙김, 과잉동일시로 구성된 6요인 모형이 3요인 혹은 2요인 모형보다 더 높은 모형적합도를 보였다. 최종 모형인 6요인 간 서로 유의미한 상관을 보이는 것으로 나타났으며 직무스트레스, 소진, 스트레스 지각, 삶의 만족도 척도들과 유의미한 상관이 있는 것으로 나타났다. 이러한 결과들은 자기자비척도가 스트레스 상황에 지속적으로 노출되는 위험요인을 낮추고, 치료적 관계를 유지할 수 있는 보호요인을 측정하는 도구임을 시사한다. 연구결과를 기반으로 연구의 함의점과 추후연구를 논의하였다.

Atomistic simulations have become useful tools for exploring new insights in materials science, but the length and time scale that can be handled with atomistic simulations are seriously limiting their practical applications. In order to make meaningful quantitative predictions, atomistic simulations are necessarily combined with higher-scale modeling. The present research is thus concerned with the development of a multi-scale model and its application to the prediction of the mechanical properties of body-centered cubic(BCC) iron with an emphasis on the coupling of atomistic molecular dynamics with meso-scale discrete dislocation dynamics modeling. In order to achieve predictive multi-scale simulations, it is necessary to properly incorporate atomistic details into the meso-scale approach. This challenge is handled with the proposed hierarchical information passing strategy from atomistic to meso-scale by obtaining material properties and dislocation mobility. Finally, this fundamental and physics-based meso-scale approach is employed for quantitative predictions of the mechanical response of single crystal iron.

본 연구의 목적은 초등학교 고학년 학생의 인터넷 게임 및 스마트폰 이용실태를 파악하고자 하였다. 2018년 10월 6일부터 2019년 9월 30일까지 K 지역 소재 16개 초등학교에 재학 중인 4~6학년 1,618명을 대상으로 자료를 수집하였고, 기술통계와 빈도분석, Chi-square를 이용하여 분석하였다. 연구결과, 인터넷 게임중독 자가진단척도(I-GUESS)는 고위험군이 6.1%로 나타났고, 스마트폰 과의존 척도(S-scale)는 잠재적 위험군 10.1%, 고위험군 0.8%로 나타났다. 인터넷 게임 및 스마트폰 사용과 관련된 신체적 문제는 36.0%가 경험했다고 응답했고, 눈의 피로가 20.4%로 가장 높았다. 정서적 문제는 18.5%에서 경험했다고 응답했으며, 분노가 6.8%로 가장 높았다. 사회적 문제는 21.8%가 경험한 것으로 파악되었고, 부모와의 갈등이 10.3%로 가장 높게 보고되었다. S-scale 점수와 I-GUESS 점수에 따른 주 사용 콘텐츠를 조사한 결과, S-scale 점수와 I-GUESS 점수가 높을수록 중계방송콘텐츠를 가장 많이 사용하는 것으로 나타났다. I-GUESS와 S-Scale 간의 상관관계에서는 I-GUESS와 S-Scale 간의 상관관계에서는 I-GUESS 점수가 고위험군 일수록, S-scale의 고위험군 비율도 높게 나타났으며, S-scale 점수가 고위험군 일수록 I-GUESS 점수의 고위험군 비율도 높은 것으로 나타났다. 향후, 이러한 변수를 고려하여 예방의 관점에서 초등학생을 위한 중재 프로그램 및 부모 교육 컨텐츠 개발이 시급함을 제언코자 한다.

Methods: The development process for the preliminary scale included construction of a conceptual framework and initial items, verification of content analysis, sentence correction, and pilot study. This study was conducted using a questionnaire survey with one-to-one interviews during January and February, 2012. Participants were 240 elderly patients with CAD. Data were analyzed using item analysis, factor analysis, criterion related validity, and internal consistency. Results: The developed scale consisted of 32 items and 6 factors - aging and disease (7 items), family relations (5 items), anxiety and withdrawal (9 items), management of daily living (3 items), compliance of medical regimen (4 items), poverty and finance (4 items), and explained 68.5% of total variance. The scale had significantly positive correlation with the Korean Perceived Stress Scale (KPSS). Cronbach's alpha was .96, and Guttman split half coefficient was .91. Conclusion: Results indicate that the Stress Scale for Elderly Patients with CAD has validity and reliability, and is a suitable scale in health care settings to assess stress in elderly patients with CAD.
