유아미,이경화 열린부모교육학회 2022 열린부모교육연구 Vol.14 No.4

The purpose of this study was to develop and validate the test instrument of parental happiness. To achieve this, the research questions were set as 'what are the concepts and components of parental happiness' and 'whether the test for parental happiness is valid'. The subjects of this study were 602 parents with children from infancy to adolescents. The procedure of this study is as follows. First, the components and initial questions of the parental happiness test were derived through the content validity of the first expert and the content evaluation of the second expert. Second, exploratory factor analysis and confirmatory factor analysis were conducted with collected data, so the validity of the parental happiness test was verified. The results were as follows. first, parental happiness was defined as emotion that had basic requirements to take care of children as parents, maintained positive relationship with family members, and felt as individuals as parents grew up. Second, as a result of exploratory factor analysis and confirmatory factor analysis, the parent happiness test was composed of 48 final items, in three categories of existence, relationship, growth, and 11 components. Third, the internal consistency and reliability of the questions were analyzed to confirm that the parental happiness test is acceptable. The parent happiness test instrument developed in this study can be used as an evaluation instrument to identify and manage individual happiness as a parent, and it will be helpful for parent role performance because of high parental efficacy. It can also be used as basic data for the development of education programs for parents and couples. 본 연구의 목적은 부모행복감 검사도구를 개발하여 타당화하는 것이다. 따라서 ‘부모행복감의 개념과 구성요인이 무엇인지’, ‘부모행복감 검사도구는 타당한지’를 연구문제로 설정하여 이를 밝혔다. 연구대상은 유아기 자녀를 둔 부모부터 청소년기 자녀를 둔 부모 602명이었다. 검사도구 개발 절차를 살펴보면 첫째, 1차 전문가 내용타당도 검증과 2차 전문가 내용평가를 통해 부모행복감 검사도구의 구성요인과 초기 검사문항을 도출하였다. 둘째, 수집된 데이터로 탐색적 요인분석과 확인적 요인분석 및 구인타당화 작업을 실시하여 부모행복감 검사도구의 타당도를 검증하였다. 연구 결과 첫째 부모행복감의 개념을 ‘부모로서 자녀를 돌볼 수 있는 기본 요건을 갖추고 있고, 가족들과 긍정적인 관계를 유지하면서 부모로서 개인이 성장해가면서 느끼는 정서’로 정의하였다. 둘째, 탐색적 요인분석과 확인적 요인분석의 결과를 통해 부모행복감 검사도구를 존재, 관계, 성장의 세 가지 범주, 11개 구성요인으로 최종 48개 문항으로 구성하였다. 셋째, 문항 내적일관성 확인과 구인타당도 검증을 통하여 부모행복감 검사도구가 수용 가능한 수준임을 확인하였다. 본 연구에서 개발된 부모행복감 검사도구는 부모로서 개인의 행복감을 파악하고 관리하는 자기보고식 평가도구로 사용할 수 있으며, 이를 기반으로 자기점검 및 성찰을 함으로써 부모 역할 수행하기에 도움을 줄 수 있을 것이며, 또한 부모 교육 및 부부 교육 프로그램 개발을 위한 기초자료로 활용될 수 있을 것이다.

The purpose of this study was to redefine the concept of parental happiness and to identify the component factors from the perspective that parents were interacting with their children and supporting children's growth, development and at the same time, parents are developing on their own happiness. Therefore, the concept and component factors were derived by previous studies and literature related to parental happiness, and the content validity of the concept and component factors was verified by experts. The total number of experts who participated in this study was 12 with 9 professionals related to pedagogy and 3 parent education experts. The results of the study were as follows: First, parent happiness was defined as being a parent, parents have the necessary conditions for raising children, can maintain a good relationship with their families such as their children and spouses, and feel that they were growing up with developmental interaction with their children. Second, the components of parent happiness were divided into existence, relationship, and growth and sub-variables for each were derived. The sub-variables of the existing domain included health, economic power, sociocultural environment, and appearance identity. The sub-variables of the relationship domain consisted of child, spouse, and parent relationships, other relationships, and social support. Sub-variables of the growth domain consisted of efficacy, positive emotion, self-growth, independence, rest and leisure.

In clinical trials, patients should be randomly allocated to treatment and control groups that consider the balance of their prognostic factors(covariates). There are many randomization methods and stratification is popular in Korea. In stratification, patients are divided into strata based on covariates and then the patients are randomly assigned to the arms of each strata. If the number of covariates increases then the number of strata increases rapidly and the results may not be reliable when the patients are inadequate in each strata. To complement this problem Pocock and Simon (1975) suggested a new randomization method that called for minimization focusing on the balance of covariates. In this study, we compare the advantages and disadvantages, the imbalance of covariates, the power of minimization, and other randomization methods by simulation.

In this paper, wetting and interfacial reaction properties for low Ag containing Sn-Ag-Cu Pb-free solder alloy, i.e., Sn-0.3Ag-0.7Cu were investigated and compared with those of Sn-1.0Ag-0.5Cu and Sn-3.0Ag-0.5Cu. Melting behavior and stress-strain curves of some Sn-xAg-xCu alloys were also measured using a differential scanning calorimeter(DSC) and a tensile test machine, respectively. In order to enhance insufficient wetting properties of Sn-0.3Ag-0.7Cu alloy, the improvement of wetting properties were analyzed by applying fluxes containing higher content of halide or indium adding of 0.2wt.% into the solder alloy. It was concluded that the small addition of indium is more effective for the improvement of wettability in low temperature range of $230{\sim}240^{\circ}C$ than applying flux containing higher content of halide.

This study aims to identify the types of adaptation to college life among college students and to analyze how mindset and career readiness predictors differ across these types of adaptation. For this purpose, an online survey was conducted targeting 210 college students, and the research questions were set as follows. The first research question was: What types of college students’ adaptation to college life can be classified? Second, what are the differences in mindset and career preparedness among the types of college students’ adaptation to college life? The findings are as follows. First, college students are categorized into three types of college life adjustment: excellent, average, and marginalized. Based on their characteristics, they are categorized into three groups. We named them as “excellent college life adaptation”, “average college life adaptation”, and “marginalized college life adaptation”. Second, we examined mindset and career readiness as factors that indicate differences between the categorized types, and found significant differences in all sub-factors of both variables. Based on the findings of this study, it is recommended that programs should be designed to help the “marginalized college life adaptation” group. Additionally, universities should identify them and provide psychological support and customized career counseling to improve their mindset and career readiness.

Sn-Ag-Cu-In-(Mn, Pd) 무연솔더의 솔더링성과 BGA 접합부 신뢰성

Sn-3.0Ag-0.5Cu 무연솔더에서 Ag 함량의 감소는 기계적 충격 신뢰성 향상에 도움이 되는 반면 솔더링성을 저하시키는 것으로 알려져 있다. 본 연구에서는 저 Ag함유 무연솔더의 솔더링성 향상을 위해 In을 첨가한 Sn-1.2Ag-0.7Cu-0.4In 4원계 조성과 여기에 미량의 Mn 및 Pd을 첨가한 무연솔더 조성에 대하여 솔더 젖음성을 평가하고, 보드 레벨 BGA 패키지의 열싸이클링 및 기계적 충격 신뢰성을 평가하였다. Sn-1.2Ag-0.7Cu 조성에 0.4 wt% In을 첨가한 합금의 젖음성은 Sn-3.0Ag-0.5Cu에 근접한 수준으로 향상되었으나, 패키지의 열싸이클링 신뢰성은 Sn-3.0Ag-0.5Cu에 미치지 못하는 것으로 나타났다. Sn-1.2Ag-0.7Cu-0.4In 조성에 0.03 wt% Pd의 첨가는 솔더 젖음성 및 패키지 신뢰성을 저하시킨 반면에 0.1 wt% Mn을 첨가한 합금은 특히 기계적 충격 신뢰성이 Sn-3.0Ag-0.5Cu는 물론 Sn-1.0Ag-0.5Cu보다도 우수한 수준으로 향상되었는데, 이는 Mn 첨가가 합금의 모듈러스를 감소시킨 데에 기인하는 것으로 생각된다.
