정부는 그동안 '초등학교에서 정보교육 시수를 확대하겠다'는 다양한 정책을 제시하였다. 그러나 2022 개정 실과(기술·가정) 교육과정에서는 여전히 정보 교육을 이전과 동일하게 17시간만을 편성하고 있고, 중학교 정보교과와의 연계성을 충분히 제시하지 않고 있다. 본 연구에서는 2019년 이후 발표된 인공지능 국가 전략, 정보교육 종합 계획, 인공지능 시대의 교육 정책 방향과 핵심 과제, 디지털 인재 양성 방안 등 초등학교 정보교육 관련 정책들을 살펴보았다. 또한, 2021년에 '2022 개정 교육과정 총론 주요 사항'이 발표된 이후, 2022년부터 시작된 실과(기술·가정) 교육과정 시안과 관련된 공청회 자료집을 분석하고, 국민참여소통채널에 올라온 댓글들을 분석한 후 실과(기술·가정) 교육과정의 문제점을 살펴보았다. 끝으로, 2022 개정 실과(기술·가정) 교육과정을 중학교 정보교과와 연계하기 위한 방안을 구체적으로 제안하고, 초등학교에서의 정보 교육을 활성화기 위한 방안을 제안하였다.

Objective: The aim of this study is to design a sampling inspection plan with human error which is changing according to inspection time. Background: Typical sampling inspection plans have been established typically based on an assumption of the perfect inspection without human error. However, most of all inspection tasks include human errors in the process of inspection. Therefore, a sampling inspection plan should be designed with consideration of imperfect inspection. Method: A model for single sampling inspection plans were proposed for the cases that visual inspection error rate is changing according to inspection time. Additionally, a sampling inspection plan for an optimal inspection time was proposed. In order to show an applied example of the proposed model, an experiment for visual inspection task was performed and the inspection error rates were measured according to the inspection time. Results: Inspection error rates changed according to inspection time. The inspection error rate could be reflected on the single sampling inspection plans for attribute. In particular, inspection error rate in an optimal inspection time may be used for a reasonable single sampling plan in a practical view. Conclusion: Human error rate in inspection tasks should be reflected on typical single sampling inspection plans. A sampling inspection plan with consideration of human error requires more sampling number than a typical sampling plan with perfect inspection. Application: The result of this research may help to determine more practical sampling inspection plan rather than typical one.

본 연구는 기술 가정 교과의 2007년 교육과정의 '나와 가족의 이해' 단원과 또한 2007년 개정 교육과정의 중학교 1학년 '청소년의 이해' 단원과 중학교 2학년 '가족의 이해' 단원에 적용할 수 있는 '청소년의 성역할과 양성평등'에 대한 실천 문제 중심의 교수 학습 과정안을 개발하여 수업의 효과를 보고자 하였다. 개발된 5차시 교수 학습 과정안은 실천적 문제 '양생평등 의식 함양과 관련하여 우리는 무엇을 해야하나?'로 1, 2, 3차시를, '양성평등 의식 실천을 위하여 우리는 무엇을 해야하나?'로 4, 5차시 교수 학습 과정안을 학교 수업에 적용하였다. 적용 대상은 경기도 의정부시 소재의 중학교 1학년 남녀합반의 4개 학급, 총 150명을 대상으로 하였다. 적용 기간은 2009년 9월 14일~9월 30일까지 3주 동안이며, 수업 적용 전에 사전 설문을 하고 개발한 양성평등 수업을 적용한 후 사후 설문을 실시하였다. '청소년의 성역할과 양성평등' 단원의 하위 요소인 개인의 성역할 발달과 진로 직업역할과 양성평등, 우리 사회와 양성평등. 가족역할과 양성평등, 양성평등 실천 전략 세우기라는 주제로 나누어 대응표본 t-검정을 통해 학습자의 양성평등 의식에 대한 고양을 가져오는지와 집안일 참여도의 효과에 대해 결과를 분석하였다. '청소년의 성역할과 양성평등' 단원을 개발한 교수 학습 과정안 적용 결과 양성성 집단이 증가하고 학습자들의 양성평등적 의식 변화에 긍정적인 결과를 보였으며, 집안일 참여도라는 학습자의 실천적 행동을 높이는 결과를 가져왔다. 또한 실천적 문제 중심의 교수 학습 과정안에 대한 학습자들의 흥미와 참여, 이해에 대한 평가는 비교적 높았다. 앞으로 학년과 단원을 넓혀서 양성평등 교수 학습 과정안을 개발하고 적용하여 지속성을 검증할 것과 양성평등 실천과 관련된 척도안이 개발되어야 할 것이다.

Purpose - This thesis is to develop a management plan and checklist by analyzing the prevention of accidents in advance by presenting the management plan for the major causes of railway accidents. Research design, data and methodology - In recent 5 years, we have analyzed the cases of railway accident, presented the management plan for the accident, and made a practical safety checklist focusing on the main measures according to the management plan. Results - The analysis of the cases of near-railway accidents suggests more concrete and practical safety management measures because the similar accidents are continuously occurring due to formal safety management. Conclusions - It is more valuable to apply to the adjacent construction of the railway line by creating a detailed checklist based on cases rather than the existing checklist. This study is written only as a human factor. For future real - time safety management, it is necessary to study more precisely cause analysis and safety equipment as a big data - based safety control system for more systematic safety management.

The objective of this study is to prepare the effective management plan of environmental noise with a noise map, and the guideline on the management plan of environmental noise was suggested through the review of existing application examples. The management plan of environmental noise with a noise map includes the practical contents in the stages of subdivision of management areas, establishment of reduction measures, opinion collection, post investigation, and reformulation of management plan. First, the classification of management regions is performed considering the excess degree of noise standard and the facility type in the phase of subdivision of management areas. Second, the optimal management plan is established through the investigation of regional characteristics and various noise reduction measures in the phase of establishment of reduction measures, which includes the examination of noise reduction effects with a noise map and the budget planning with the costing of noise reduction measures. Third, the opinion survey with a local resident and a expert is carried out in order to prove the validity of the management plan in the phase of opinion collection, and the management plan is modified with gathered opinions. Fourth, the post examination plan with noise measurement is performed in order to verify the real effect of noise reduction measures according to the management plan in the phase of post investigation. Finally, the amendment of the management plan as well as the improvement of a noise map is carried out at a regular cycle in the phase of reformulation of management plan.

This paper deals with implementation of an expert system to obtain an optimal plan of load transfer for fault restoration with the capability of security monitoring and assessment in distribution systems. Based on the technique of load transfer tree analysis, the proposed expert system can afford to assist system operators in proposing an optimal plan of load transfer for fault restoration, In paticular, an application of the proposed ES to practical distribution systems yields an optimal load transfer plan which ensures system security by considering security assessment for contingency of feeders and main transformers in the knowledge based sense.

본 연구는 대전광역시의 주요 산줄기 분포 현황 및 단절지점을 파악하고, 평가를 통해 우선복원지점을 선정하기 위해 실시되었다. 신상경표에 의한 산줄기 분포현황을 파악한 결과, 대전광역시는 3개의 지맥과 이들 지맥에서 뻗어 나온 10개의 세맥이 분포하고 있었다. 또한 주요 산줄기와 도로망을 중첩하여 산줄기 단절지점을 파악한 결과 총 31개의 단절지점 중 12개의 복원가능지점이 선정되었다. 평가지표 및 평가모형을 개발하여 산줄기 우선복원지점을 평가한 결과, I등급은 4개, II등급은 5개, III등급은 3개 지점이 선정되었다. 이를 바탕으로 각 등급별 차별화된 복원방안을 3가지로 구분하여 제시하였다. 향후 객관적인 평가모형 개발 및 구체적인 지점별 복원방안에 대한 방법론이 제시되어야 할 것으로 생각된다.

This study was carried out to investigate the future plan for infant feeding practice and its associated factors among university students so as to develop focus for nutritional education program for the promotion of breastfeeding. The subjects were 301 students (males 130, females 171). The results obtained were as follows. In this survey, the subjects had a basic knowledge of breastfeeding and lactation, especially of the ingredient of breastmilk. However they were not well informed about the physiology and method of breastfeeding and benefits of breastfeeding for mothers. The average scores far attitude toward breastfeeding and lactation were 3.09 points on a 4 point scale, which indicated a slightly positive attitudes toward breastfeeding. However the participants had a negative attitude toward its emotional and practical aspects. Their future plan for infant feeding was breastfeeding 40.3%, formula feeding 3.0% and mixed feeding 56.7%. A concern was that the students showed a high rate with regard to a mixed feeding plan, and Dey decided this based on an incorrect knowledge of breastfeeding. The group who planned to breastfeed in the future (BF) showed higher scores with respect to knowledge and attitudes than those who planned to formula feed or mixed feed (FF + MF). Therefore, to encourage mothers to breastfeed and support breastfeeding, breastfeeding nutritional education is urgently needed among university students. In addition, nutrition education programs should promote the benefits of breastfeeding for mothers and the physiology and practical method of breastfeeding. Also a practical and culturally sensitive course about food and nutrition is recommended to inform participants about breastfeeding. (Korean J Community Nutrition 8(2) : 240∼249, 2003)
