  • 최근에 내무부에서는 개발사업으로 인한 토사유출 피해 중 인명과 재산 피해와 같은 재해 성격을 가진 대규모 토사유출을 사전에 미리 저감시킬 목적으로 재해영향평가제를 도입하여 추진하고 있다. 이에 따라 건설 엔지니어링 업계에서는 대규모 개발 사업으로 인한 가속화된 토양손실량 예측과 침사지 설계에 많은 관심이 쏟아지고 있으나 이 분야의 기술축적과 자료부족으로 과업수행에 어려움을 겪고 있다. 본 강좌에서는 이러한 엔지니어링 업계의 기술적인 어려움을 다소 나마 해소할수 있도록 개발사업으로 인한 가속화된 토양손실량 예측방법과 침사지 설계 기준에 대해 외국의 자료를 바탕으로 그 동안 국내에서 수행한 각종 재해영향평가 자료를 검토하여 제시한다. 먼저, 재해영향평가제의 취지, 토사유출과 재해, 토사유출 재해 저감대책 등에 대해 간략히 설명한다. 다음, 침식량 예측 방법으로 미국의 범용토양 손실공식(USEL) 방법의 적용 절차에 대해 구체적으로 소개한다. 침사지 설계 편에서는 침사지 설계 개념과 구체적인 설계 절차를 제시하고 참사지 규모의 결정방법을 소개한다. 본 강좌의 교재는 미국교통연구단(TRB)의 국립합동도로연구프로그램(NCHRP)#70 자료를 주로 참고하였다. 이 자료는 부록에 원본 전부를 수록하였다. 다만 아직 이 분야 연구가 미흡한 관계로 본 강좌에서는 재해저감 측면에서 합리적인 침사지 설계 기준을 완전히 제시하지 못하고 있다. 참고로 국립방재연구소의 박무종/강대환 연구팀이 기존의 재해영향평가서 자료 중에서 10개를 선정하여 침사지 소요수면적 산정, USEL 적용, 강우침식도 R의 산정 등에 대해 사례 조사 분석한 결과를 부록에 수록하였다.을 기해야 한다. 있다. 청주권의 무심천도 계획상은 대청댐의 물을 공급 받을수도 있도록 되어 있으나 현실상으로 상수도 원수로서의 공급마저도 매년 심한 원수 수질 문제(5-6월, 10월경의 취수장 부근의 부영양화 현상으로 인한 악취와 물 맛의 문제)를 1984년부터 겪고 있다. 이와 같이 도시권 하천의 수자원은 자연적, 인위적, 경제적, 법적, 제도적 여러 제한 요소로서 특성을 가지고 있으며 이는 날로 심해 가고 있는 실정이다. 그러므로 최적 물관리 시스템의 개발이 새로이 시작하는 수자원 개발 사업에서는 계획 단계에서부터 절실히 요구되는 바이며 기존 시설물의 관리 운영은 과감히 그 운영 관리 기준을 보완 재 정비하여야 할 것이다. 지금까지 대부분의 수자원 종합 개발 계획이 홍수방이나 용수 공급 및 수력 개발 등에 주력하여 왔으나 이제는 보다 더 수자원의 환경 보전적 차원과 도시의 안정적 발달을 위한 지역 및 권역 계획과 연계지워져서 양적인 안정 공급과 더불어 질적인 향상과 연계지워서 경제-사회적 요구에 부응할 수 있도록 도시권의 수자원을 최적 관리할 수 있는 방안을 강구하여야 할 것이다. 이는 각 도시 하천의 수자원의 정량적·정성적인 특성 및 제한 요소를 충분히 감안하여 수요-공급 개념에 의하여 과감히 기존 시설(예: 팔당댐의 운영, 대청댐의 운영 등)의 관리 운영 체계를 개선하여 나가야 할 것이며, 수질 보전적-환경 보전 차원에서 저수관리 체계를 확고히 할 수 있는 방안을 강구하여야 할 것이다.펄스주입법에 의해 증착된 박박은 강유전성 이력을 나타내었다.지역과 비도시지역을 비교하는 조사 연구가 필요하며, 이러한 조사결과를 바탕으로 자녀의 식습관에 대

  • In Asia, where the aging population is growing rapidly, as the funeral service industry develops and the market grows. The economic value and interest of funeral services is increasing. However, Korea's funeral services are being developed in a biased direction, focusing only on funeral services, after death. Compared to the case of advanced funeral services in the United States, the United Kingdom, and Japan, not only the funeral but also the care of the deceased's family and acquaintances around us are developing. It is appropriate to use a method based on ethnography and User eXperience. For this purpose, the method of collecting and analyzing the ethnography and user experience data of actual resident and visitor was deduced in persona method in the next ten years, and funeral service centered on resident and visitor. In this study, qualitative data centered on the future direction of funeral services, focusing on the resident (family) and the guest who are the principals of services from the perspective of service science. It is difficult to derive meaningful results from the process of collecting, processing, and interpreting big data in general, and in this case, the data analysis method is based on ethnography and user eXperience.) Is appropriate. For this purpose, the method of collecting and analyzing the ethnography and user experience data of the actual resident and the visitor was deduced in the persona method in detail after 10 years. In addition, the future direction of funeral services centered on residence and visitor was presented.

  • Pedagogical Content Knowledge (PCK) is intrinsically domain/topic-specific knowledge for teachers' expertise. On the basis of this idea about PCK, we investigated in-service science teachers' topic-specific PCK on the unit of stars and universe in terms of teachers' knowledge and practices. We observed four middle school science teachers' classes for eighth graders, and took the videos of the classes. The topics of the classes covered constellation, annual parallax and the distance of stars, and the expansion of the universe. We also examined the teachers' pedagogical thinking through video stimulated recall interviews. In addition, we developed a protocol to analyze the levels of participant teachers' PCK and the characteristics revealed in their classes on each topic. Results of the study showed that the participant teachers' level of PCK varied across the topics of classes and the sub-components of PCK. We also identified teaching orientations played key roles in shaping overall characteristics of their PCK. Moreover, astronomical thinking such as spatial thinking and system thinking, was not appropriately embedded as the specific practices into the astronomical concepts in their instructions. We discussed the implications on the progressions of teachers' PCK in terms of their professional development.

  • In Korea, playgrounds have been developed quantitatively and qualitatively. However, there is a lack of interest in the play needs of children with disabilities. With this in mind, this study is concerned about the planning and design process of the inclusive playground constructed in 2016 at Seoul Children's Grand Park. The case study covered the Kkumtle Kkumtle playground in Seoul Children's Grand Park and was completed in December 2015. This playground is the first case of an inclusive playground ever built in Korea. The concept of the inclusive playground established in this study is: (1) a playground where not only children with disabilities but both children with disabilities and children without disabilities can play together; (2) a playground for both children with disabilities accompanied by their families and children without disabilities accompanied by family members with disabilities; (3) a playground that ensures universal accessibility to the entire space including play facilities; and (4) a playground where the most essential functions of a playground-fun, curiosity, and adventure-are centered on various activities. In conclusion, we presented limitations and opinions for improvements to design and policy proposals for social expansion of inclusive playgrounds. There are three ways to overcome limitations in design. First, there is a need for an in-depth study of play characteristics by type of disabilities of children. Second, it is necessary to develop facilities suitable for the actual situation of Korea through various social experiments. Third, if the inclusive playground centered on facilities is presented in this study, then several types of integrated playgrounds should be implemented in the future.

  • This study is devised out of the recognition that the existing standardization-related research has not sufficiently examined the overall social environment where a standard is actually made and diffused and the roles of the actors and the changes in them in the complex social system where multiple stakeholders exist. Against this backdrop, this study purports to reconstruct the dynamic process of developing and standardizing an innovative technology through a socio-technical approach involved by multiple stakeholders with different interests in the context of a socio-technical institutional environment. The specific goals to achieve the purpose include first, inspecting the characteristics of the interactions between the human actors and between the human and non-human actors in the socio-technical network surrounding a standardization process. Second, the study aimed to observe the activities of the focal actor who led the standardization process and its changing role. To that end, it analyzed the dynamic features of the process of standardizing a HD 3DTV broadcasting technology that took place in South Korea based on the actor network theory. As for the analysis method, the researchers personally took part in the actor network involving the new technology to analyze the dynamic characteristics of the network, applying the qualitative research method of survey and in-depth interviews and exploring the overall dynamics of environment, behavior and technology observed over the course of the entire standardization process.

  • The purpose of this study is to explore the meaning of the essence through the parenting experience of the mother with ADHD child and to divide the parenting experience into the domains and categories. The data was collected through several depth interviews with 12 semi-structured questionnaires of the mother with ADHD child. The analysis of the data has adopted a consensus qualitative research method(CQR) that describes the phenomenon based on the collected data and can deduce inductive conclusions. Through CQR, various experiences of ADHD mothers were deeply analyzed. Through the consensus process, 12 cases were combined and quantified to understand the overall pattern and specificity. As a result, 11 domains and 51 categories were derived. The 11 areas were classified as 'Ignorance of ADHD symptom', 'Confronting ADHD diagnosis', 'Peripheral reaction after ADHD diagnosis', 'Acceptance of ADHD diagnosis', 'Ambivalence for medication', 'ADHD active treatment intervention', 'Family support','Social support', 'Social perception change', and 'Mature parent'. This suggests that early treatment and intervention for ADHD child is significant. Also, appropriate intervention is required based on accurate understanding through acceptance of ADHD diagnosis and that parent education can lead to positive life for child and mother of ADHD. Finally, based on this, I made suggestions the future research.

  • This study aims to investigate causes of the emergence of so-called 'family-care workers' in the Long-term Care Insurance system in Korea. The LTCI system introduced in 2008 financially support the utilization of formal care services for the eligible elderly with care needs by paying for services of their care workers. Interestingly, 38.4 percent of payments for the in-home services were claimed by family members registered as qualified long-term care workers in 2012. We interviewed ten family care workers in depth and analyzed the needs of the aged and their families to explain the emergence of family care workers. The emergence of family-care workers is an inevitable result of choice by family members who face a dual burden of living and caring; be the additional choice following discharge the duty to support the elderly; be the alternative choice to fulfill unaccepted needs for services. These results suggest the needs for a comprehensive public provision of both income and social service support for the aged and an introduction of financial support for family care complementing the formal care support in the LTCI in Korea.

  • This study suggests a plan for revitalizing return-to-farming / fishing villages through the marine leisure industry by analyzing the practical problems faced by young and older adults who have returned to the marine leisure field. A case study was conducted to identify the problems faced by those returning to marine leisure, and to determine the measures for revitalizing return-to-farming / fishing villages. Interview participants were those returning to marine leisure and experts in related fields. The problems identified include the exclusive culture of fishing villages, difficulty in raising initial investment funds, and lack of marine leisure education programs for return-to-farming / fishing villages. The proposals to solve these problems and revitalize return-to-farming / fishing villages through the marine leisure industry include the introduction of an incentive system to mitigate barriers to entry; establishment of a matching system; use of idle land in fishing villages to promote return-to-farming / fishing villages; introduction of a consignment management system after the pre-investment of the fishing villages; and establishment of an education program, including in the fisheries field, and infrastructure for return-to-farming / fishing villages for marine leisure.

Case Study on Teaching Practice for Biological Adaptation of Elementary School Teachers: Focus on the Influence of Teacher's Guide and Teachers' Understanding and Belief of Biological Evolution (초등교사의 생물의 적응에 관한 수업에서 나타난 교수실행 사례 연구 -교사용 지도서와 교사의 진화 개념 이해 및 신념의 영향을 중심으로-)

  • In this study, we examine whether the description of the elementary science curriculum guide, the concept of evolution, and the beliefs of teachers affect the teaching practice in classes related to adaptation of elementary school teachers. First, we examined the alternative concept among the sentences described in the bio-adaptation-related unit of the 2009 Elementary Science Curriculum Teacher's Guide and identified the effects of this description on the teaching practice of elementary school teachers. Next, six elementary school teachers were classified according to the results of the evolutionary concept test paper and the evolutionary belief test paper, and based on the class recording data and interview data, whether there is a difference in teaching execution. As a result, it was confirmed that there were a total of 18 descriptions corresponding to the concept of evolutionary alternatives in the analysis of instruction descriptions, and that these descriptions influenced elementary school teachers' adaptation concepts and teaching practice. Next, the group with high and low levels of evolution differ in the areas of "recognition of importance in the unit, distinction between adaptation concepts in the general sense and adaptation concepts in the biological sense, errors in the class," and "recognition of evolutionary education needs in the elementary curriculum." This study is meaningful in that it qualitatively confirms the research on the evolution concept of elementary school teachers, which has been approached quantitatively, and in-depth, confirms how the description, evolution concepts, and evolutionary beliefs affect elementary school teachers' biological adaptation concepts.

  • One of the main roles of the science teacher is to help students become active agents in their learning of science. This study described how an elementary science teacher used students' emotional resources to conduct emotionally responsive teaching and what were the learning outcomes of this approach. The participants of the study included the teacher himself and his 6th grade students, and emotionally responsive teaching was applied in the science unit of 'Various Living Things and Our Human Lives'. Multiple types of data, including the teacher's teaching logs, video recordings of the lessons in the unit, and interviews with the students, were collected. The data were analyzed qualitatively, and the results were described using a self-study method. The teacher took advantage of three kinds of students' emotional resources (i.e., character drawing, t-shirt design, and raps) to organize his emotionally responsive teaching. The learning outcome included the students' positive emotions and active participation in science lessons, their epistemic practices such as explorations and justifications of knowledge, and the students' reconstruction of knowledge in consideration of their everyday lives. It was suggested that emotionally responsive teaching can promote elementary school students' active participation in science learning, resulting in meaningful learning outcomes in emotional, cognitive, and conceptual aspects. Further studies should thus be conducted to understand the characteristics of emotionally responsive teaching and its detailed teaching strategies.
