고속도로 평면선형상 사고빈도분포 추정을 통한 음이항회귀모형 개발 (기하구조요인을 중심으로)

강민욱,도철웅,손봉수 대한교통학회 2002 대한교통학회지 Vol.20 No.7

교통사고예측 및 예방을 위해서는 실제적으로 도로설계과정에서 제어가 가능한 도로 기하구조요소에 대한 사고관계를 파악함이 타당하다. 즉, 도로의 설계자는 도로건설에 앞서 기하구조요소와 사고와의 관계를 현장자료를 통해 정확히 밝혀 도로설계에 반영해야 한다. 이를 위해, 교통사고의 빈도분포를 박히는 것은 가장 기본이 되는 일이며, 교통사고 예측모형개발에 선행되어야 한다. 일반적으로 교통사고건수의 경우 분산이 평균보다 큰 과분산(overdispersion)의 특징을 가지고 있어 음이항 분포를 따른다고 알려져 있다. 따라서 본 논문은 사고모형의 개발에 앞서, 사고발생지점에 대한 도로설계요소와 기타 잠재적인 사고발생 관련요인이 비교적 잘 파악되어있는 호남고속도로를 중심으로 평면 선형상 곡선부에 대하여 교통사고의 분포를 적합도 검정을 통해 알아보고자 하였다. 사고자료는 한국도로송사의 호남고속도로 5년(1996∼2000)간 자료를 분석에 맞게 정리하였으며, 강민욱과 송봉수(2002)에서 제시한 평면선형에 있어서의 구간분할법을 이용하여 배향곡선구간과 단일곡선구간에 대한 사고분석을 하였다. 적합도 분석결과, 예상대로 음이항분포가 사고건수를 설명하기에 가장 적합한 확률분포로 제시되었으며, 이를 통해 최우추정법을 이용한 음이항회귀모형을 개발하였다. 구간분할법을 적용한 음이항회귀모형의 경우, 기존의 확률회귀토형에 비하여 높은 결정계수를 갖았으며, 모형에서 적용된 기하구조요소로는 차량 노출계수, 곡선반경, 단위거리 당 편경사변화값 등이다.

ICN+DTN 기술

강민욱,정윤원 한국통신학회 2017 정보와 통신 Vol.34 No.12

최근 인터넷에서 동영상 트래픽 등으로 인한 인터넷 트래픽 급격한 증가 문제를 해결하기 위해 제안된 정보 중심 네트워크인 ICN(Information Centric Network)과 연결성이 보장되지 않는 환경에서 메시지를 효과적으로 전달할 수 있는 지연 감내 네트워크인 DTN(Delay Tolerant Network)을 결합한 ICN+DTN 연구가 재난 환경을 대상으로 활발히 이루어지고 있다. 재난 환경에서는 통신 인프라의 파괴로 인해 네트워크의 연결성이 보장되지 않는다. 따라서, 컨텐츠 이름 기반으로 기회적 접촉을 통한 메시지 전달을 수행하는 ICN+DTN 기술은 재난환경에서 노드 간 메시지 전송에 매우 효과적이라 할 수 있다. 이에 본고에서는 ICN 및 DTN 기술의 원리에 대해 간략히 알아보고 이를 결합한 ICN+DTN 기술 및 관련 프로젝트의 동향을 소개한다.

At the national level, safety education is emphasized under institutional and policy support. Although it has not been long since the discussion on water safety education in Korea, there will be no objection to the background importance and necessity of survival swimming education. Based on the 2018 National Safety Education Implementation Plan is expected to analyze the current state of survival swimming education for elementary school students and conduct primary research to develop educational manuals. In order to achieve the purpose of the study, the Focus Group Interview and Systematic Literature Review were attempted. In the case of 2021, due to COVID-19 survival swimming education at school was not going on. However, study participants related to survival swimming career can vividly hear the voices of the field. The conclusion is as follows. First, there are still conflicting views on survival swimming education, contrary to the original positive intention of the physical education policy. Second, the current survival swimming education manual can effectively improve swimming skills. However, some points need to be supplemented as it is an integrated alternative to water safety. Third, to develop the survival swimming education manual in the future, it is necessary to present action guidelines assuming various crises and find a way to accommodate all education targets.

In the middle and high school physical education classes, there was a steady interest in the participation of female students in physical education class. This phenomenon has existed, and in reality, the PE teachers have set the purpose of this study in order to identify the strategies for participating in the PE classes of female students. The research problems to solve this research purpose are as follows. First, what are the prejudices about PE teachers' female students in PE classes?, And second, what are the classroom strategies according to prejudice of female students in PE classes of PE teachers? Participants of the study set up a less than 15-year experience in PE teachers who can be most attentive to classroom strategies and PE classes and interviews according to previous research. Data collection was conducted through in-depth interviews, email and SNS, and analyzed through inductive categorization. The results are as follows. First, in the PE class, the prejudice of the PE teacher to the female student will hate the PE class, and the PE time will be a little hard and the rest will think as the free time. Second, in the PE class of PE teachers, the class strategy based on prejudice against female students is to use emotional appeal principle, to induce participation in PE class through negotiation, to use issue, to stay well with Dae-Jang(leadership and popular student) It is the induction of interest and interest through. 지금까지 학교체육에서 여학생의 참여를 활성화하기 위한 학계의 관심은 꾸준히 이어지고 있다. 이러한 관심은 여학생의 신체활동 참여 기회의 확대, 남성 중심의 체육수업에서 양성평등이 실현되는 형태로 변화를 촉구하고 있다. 하지만 교육 현장에서 여학생들은 체육수업 참여에 있어 여전히 주변부에 머물러있는 실정이다. 이 연구의 목적은 여학생들이 체육수업 참여에서 마주하는 장벽을 체육교사의 관점에서 해석하고자 한다. 이러한 연구목적을 해결하기 위한 연구문제는 다음과 같다. 첫째, 체육수업에서 체육교사의 여학생에 대한 편견은 무엇인가?, 둘째, 체육교사의 체육수업에서 여학생에 대한 편견에 따른 수업전략은 어떠한가?. 연구 참여자 선정 기준은 선행연구에 따라 수업전략에 대한 고민과 체육수업 및 인터뷰에 성실하게 임할 것이라 판단되는 경력 15년 미만의 체육교사로 설정하였다. 체육교사의 수업실태와 수업전략에 관한 문헌고찰과 심층면담 및 이메일(email), SNS를 활용한 자료 수집의 절차를 거쳤으며, 귀납적 범주화 과정을 통하여 자료를 분석하였다. 도출된 결과는 다음과 같다. 첫째, 체육수업에서 체육교사의 여학생에 대한 편견은 ‘여학생은 체육수업을 싫어할 것’과 ‘체육시간은 잠깐 힘들고 나머진 자유 시간으로 생각할 것’으로 나타났다. 둘째, 체육교사의 체육수업에서 여학생에 대한 편견에 따른 수업전략은 ‘감정적 호소 원리의 활용’, ‘협상을 통한 체육수업 참여 유도’, ‘이슈의 활용’, ‘대장(리더십과 인기 있는 학생)과 잘 지내기’, ‘스포츠 룰 변경을 통한 관심과 흥미 유도’로 나타났다.

The purpose of this study is to examine relationships between social support, school engagement, and after-school sport participation among elementary school students from multicultural families. A questionnaire survey was conducted with a sample of elementary school students from multicultural family background – 3th ­6th grade students selected from schools located in Gyeonggi Province (Ansan-si, Icheon-si, Siheung-si, Suwon-si), Korea in 2013. A total of 225 questionnaires were collected. Statistical analyses were used to analyze the data, including confirmatory factor analysis, reliability analysis, frequency, MANOVA, multiple regression analysis. The results are as follows. First, as to the types of after-school programs, participants in sport programs showed statistically higher scores in both social support and school engagement than participants in other programs including academics, arts, and non-participation. Second, statistically significant correlational relationships were found between variables of social support and school engagement among participants in after-school sport programs. As to social support, the period of after-school sport program participation was found to have an significant influence on both parent support and peer support. As to school engagement, the frequency of after-school sport program participation was found to have an significant influence on cognitive engagement.
