김경화 한국미래교육학회 2019 미래교육연구 Vol.9 No.3

The purpose of this study was to analyze the meaning of the instructional experiences of preservice teachers having the experience of blended PBL instruction in college. A survey was conducted on 128 students at a college located in an urban community, and data were gathered to make a qualitative research including reflective journals, this researcher's journal and e-instruction materials. As a result of making this study, PBL was found to have the largest effect on "problem-solving skills," followed by "cooperative learning skills," "communicative competency," "self-directed learning capabilities" and "learning motivation." In addition, the students gained positive experiences through blended PBL instructions: "Feeling great as a motivated learner and significant activities," "feeling a sense of achievement through self-directed learning," "flexible thinking and extension of thinking," "better self-understanding and greater confidence." It suggests that blended PBL instruction is closely associated with the development of the competencies of talented people who will take the initiative in the future era of the 4th industrial revolution, To ensure the efficiency of blended PBL instruction, the kind of instructional design that could maximize the strengths of online and offline instructions is necessary, and the active participation of the learner and the teacher's role performance as a facilitator and guide are required as well. To make them happen, various kinds of support need to be provided sufficiently in consideration of the characteristics of teachers who intend to conduct blended PBL instruction. 이 연구는 대학교에서 블렌디드 PBL 수업을 경험한 예비교사들의 수업경험에 대한 의미를 분석하고자 하는데 주 목적이 있다. 연구를 위해 G시에 소재한 K대학교 재학생 128명을 대상으로 설문을 실시하였고 질적 연구를 위해 성찰일지, 연구자일지, e-class 탑재 자료 등을 통해 자료를 수집하였다. 연구결과 학습자의 주요변인별 블렌디드 PBL 효과는 ‘문제해결 능력’, ‘협동학습 능력’, ‘의사소통 능력’, ‘자기주도학습 능력’, ‘학습동기’ 순으로 높게 나타났다. 또한 블렌디드 PBL 수업을 통해 ‘학습의 주체자로서의 뿌듯함과 의미 있는 활동’, ‘자기주도학습에 대한 성취감’, ‘유연한 사고 및 사고의 확장’, ‘자기이해 및 자신감 향상’ 등 긍정적인 경험이 이루어졌다. 이는 블렌디드 PBL 수업방법이 4차 산업혁명 시대의 미래를 주도할 인재의 역량 제고와 깊은 연관성이 있음을 시사한다. 효율적인 블렌디드 PBL 수업을 위해 온·오프라인의 장점을 극대화할 수 있는 수업설계, 학습자의 능동적 참여, 그리고 촉진자, 가이드로서의 교수자의 역할 등이 더욱 요구되어진다. 이를 위해 블렌디드 PBL 수업을 적용하려는 교수자의 특성을 고려한 다양한 형태의 지원이 충분히 이루어질 필요가 있다.

본 연구는 중장년 구직자를 대상으로 강점 기반 자기인식 취업 역량 강화프로그램이 우울 민감성, 회복탄력성 및 구직 준비도에 미치는 긍정적인 효과를 알아보고자 하였다. 서울의 직업훈련 기관과 고용서비스 기관의 구직자 혹은 구직 예정자 중 자발적 동의를 한 실험군 16명, 대조군 16명이 참여하였으며, 실험군은‘강점 기반 자기인식 취업 역량 강화 프로그램’을 하루 4시간씩, 주 2회, 5주 동안 10회기를 실시하였다. 두 집단 모두 프로그램 전·후 우울 민감성 척도, 회복탄력성 척도 및 구직준비도 검사를 실시하였다. 그 결과 강점 기반 자기인식 취업 역량 강화 프로그램의 실험군은 대조군 보다 우울 민감성이 유의하게 감소하였으며(p<0.05), 대조군에 비해 실험군은 회복탄력성, 구직 동기, 구직기술이 유의하게 향상되었다(p<0.05). 따라서 강점 기반 자기인식 취업 역량 강화 프로그램은 심리적 요소인 우울 민감성과 회복탄력성의 정서와 구직준비의 인지 요소인 구직 동기와 구직준비의 행동 요소인 구직기술의 변화를 통해 중장년의 취업지원 방법으로 제안할 수 있다. The purpose of this study is to verify the positive effects of a strength-based self-aware employment competency strengthening program on depression sensitivity, resilience, and job-seeking readiness for middle-aged job seekers. Among job seekers or prospective job seekers at vocational training institutions and employment service agencies in Seoul, 16 experimental groups and 16 control groups voluntarily consented and participated in a “strength-based self-recognition job competency strengthening program” that was administered to the experimental group for 4 hours a day, two times a week, in 10 sessions for 5 weeks. Both groups took a depression sensitivity scale, resilience scale, and job search readiness test before and after the program. As a result, the experimental group of the program showed a significant decrease in depression sensitivity compared to the control group, and the experimental group significantly improved resilience, job-seeking motivation, and job-seeking skills compared to the control group. (p<0.05). Therefore, this study conducted a strength-based job competency strengthening program for the middle-aged to verify changes in individual psychological factors and job-seeking preparation. The program can be suggested as a method of employment support for middle-aged and older adults through changes in emotional factors such as depression sensitivity and resilience, which are psychological factors, and job-seeking motivation, which is a cognitive factor of job-seeking preparation, and job-seeking skills, which are behavioral factors.

When a fault occurs in a DC distribution system, the outage area may be extended due to rapid shutdown of the main converter. Because the magnitude of fault current has a limit to protect coordination in a DC distribution system, an operation method is required to rapidly isolate a fault section by considering slope characteristics of the fault current. Therefore, this paper proposes an operation method for an intelligent fault isolation device (IFID), which can detect and estimate a fault in a rapid and accurate way by considering slope characteristics of the fault current with distribution line constants. The proposed operation method for an IFID calculates the slope of the fault current with distribution line constants and reduces its operation time by comparing the calculated slope value to a setting value to detect and evaluate the fault condition. Moreover, we implemented a DC 350-V, 4-kW-scale IFID consisting of H/W and S/W sections based on the proposed operation method. The H/W section is composed of main and current limit switches, a current limit resistor, voltage and current sensors, and an SMPS. The S/W section consists of a control board and CCS to calculate the slope characteristics of the fault current and control a semiconductor device. From the test results based on the proposed operation method, it was confirmed that the IFID considering slope characteristics of the fault current can detect and evaluate the fault condition and limit the fault current faster than an existing method that considers the fault current only.

농촌 노인의 지역사회 물리적 환경에 대한 인식이 행복감에 미치는 영향: 공동체의식의 조절효과 검증

김경화,신동호,최윤지,윤순덕 한국농촌사회학회 2023 農村社會 Vol.33 No.2

본 연구는 농촌 노인의 지역사회 물리적 환경에 대한 인식과 공동체의식이 행복감에 미치는 영향력을 살펴보고, 지역사회 물리적 환경 인식과 행복감 간 공동체의식이 조절 효과를 갖는지 분석하고자 하였다. 본 연구를 위해 ‘2020 농어업인 등에대한 복지실태조사’ 데이터를 활용하였다. 65세 이상 2,654명의 노인을 연구대상으로 선정하여, 기술통계 분석, 요인분석, 상관관계 분석, 위계적 회귀분석을 실시하였다. 조사결과를 요약하면 다음과 같다. 농촌 노인 행복감의 평균은 보통 정도의수준이었으며, 소득수준 및 건강상태에 따라 차이를 보였다. 지역사회 물리적 환경에 대한 인식의 하위영역 중 생활인프라 인식은 행복감에 유의한 영향을 나타내었으나, 안전·경관 인식은 농촌 노인의 행복감에 유의한 영향을 미치지 않았다. 공동체 의식의 행복감에 대한 영향력을 분석한 결과, 공동체의식이 높을수록 농촌 노인이 행복감을 더 많이 지각하는 것으로 제시되었다. 농촌 노인의 공동체의식은 생활인프라 인식과 행복감 간의 관계에서 조절효과가 있는 것으로 분석되었다. 공동체의식이 낮은 경우에 비해 공동체의식이 높은 경우, 생활인프라 인식이 행복감에 미치는 영향력이 보다 작은 것으로 나타났다. 본 연구결과를 바탕으로 농촌 노인의행복감을 증진 시킬 수 있는 방안에 대해 논의하였다. This study sought to analyze how perception of the community's physical environment and sense of community affect the happiness of rural seniors and to identify the moderating effect of sense of community. For this study, data from the ‘2020 Welfare Survey on Farmers, Fishermen, etc.’ was used. 2,654 elderly people aged 65 years or older were selected as research subjects, and descriptive statistical analysis, factor analysis, correlation analysis, and hierarchical regression analysis were performed. The summary of the survey results is as follows. The average happiness of rural seniors was average, but there were differences depending on income level and health status. Among the sub-domains of perception of the community's physical environment, perception of safety and scenery did not have a significant effect on the sense of happiness of rural seniors, and perception of living infrastructure was a variable that significantly influenced the sense of happiness. As a result of analyzing the influence of sense of community on happiness, it was shown that the higher the sense of community, the more happiness the elderly in rural areas perceived. The sense of community of rural seniors was analyzed to have a moderating effect in the relationship between perception of living infrastructure and happiness. It was found that when the sense of community was high compared to when the sense of community was low, the influence of perception of living infrastructure on happiness was smaller. Based on the results of this study, ways to improve the happiness of rural seniors were discussed.
