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.

The importance of sports welfare are emphasized, but the concept of sports welfare is still at an abstract level. The purpose of this study is to look at the changes in sports facilities supply policy and conceptually define the sports facilities. According to data analysis second data were chosen, related laws and policy reports. Literature review process, and the changes in sports facilities supply policy by the Priestley’s multi-paradigm theory were analysed. The results are as follows, sports facilities were targeted for elite sports training purposes, and a sports for all movement for people was passive. Since the government's deregulation policy, the public characteristic of sports facilities has been increasingly highlighted, such as the ability to manage and the operating system. Since 1998, the rise of welfare budgets and social services has increased due to the advent of the progressive government, and the importance of social welfare. The more importantly the supply of sports facilities has increased. Based on Priestley’s multi-paradigm theory, the viewpoint of sports facilities changed from individual responsibility to social responsibility.

Purpose: The emergency department is prone to medical errors due to the patients’acuity and complexity. Collection and monitoring of data on medical errors are essential for setting priorities and improving patient safety. Methods: Emergency physicians report medical errors voluntarily with an intranet-based error reporting system. The system is confidential and anonymous. Data on medical errors was collected at the emergency department of a tertiary teaching hospital with approximately 76,000 annual visits, during a nine-month period from April to December 2008. The collected data was analyzed prospectively. Results: Of the 238 reports collected, 204 errors were analyzed. 90.6% of the errors were related to doctors and 21%were related to nurses. Error types were classified into clinical errors (57%), medication errors (7%) and administrative errors (35%). The levels of impact on patients caused by these errors were classified as near-miss in 28 (13%), no harm in 93 (45%), mild harm in 66 (32%), lethal in 5 (2%)and death in 2 (1%) cases. Errors that occurred in the elderly group (over 60 years of age) had more harmful impact than in other age groups (p=0.0003). The causes of these errors were human in 147 (72%), systems in 23(11%) and both human and systems in 34 (17%). Most of these errors were preventable (99%). Conclusion: Data collected by the intranet-based medical error reporting system is useful to classify and analyze medical errors, and is also essential in the implementation of a patient safety system.

The purpose of this study is to examine the results of previous studies to the effects of participation in sports for autistic disabilities. The meta-analysis has academic significance in that it can verify the impact on the health of the autism. In order to meta-analyze the effects of participation of autism on sports, The period of study was limited to 2000 to 2020 as of the publication date of the research targeting the Korean Ciatation Index. Meta regression analysis based on the meta-analysis procedure CMA(Comprehensive Meta Analysis) method was performed on the collected data. STATA 15.0 ver statistical program was used for data analysis. The results are as follows. First, it was found that the overall effect size of autism people's participation in sports was high. Second, there was a difference in the effect size of each autism person participating in sports.

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.

강민욱,김경아,김남순,노시갑,강석우,이진성 한국잠사학회 2005 International Journal of Industrial Entomology Vol.10 No.2

In this study, we describe the Bombyx mandarina hemolin cDNA. A sequence analysis of cDNA revealed a single open reading frame (ORF) of 1233 nucleotides. The deduced 410 amino acid sequence of B. mandarina hemolin contains 4 imunoglobulin (Ig) C-2 type domains. B. mandarina hemolin cDNA showed the highest sequence homology to known those of B. mori.The developmental profile in terms of expression level of hemolin mRNA was determined in the absence of a bacterial challenge. Hemolin mRNA was detected only in mid-gut, but not in hemocytes, fat body, testis, and silkglands. Hemolin mRNA in mid-gut was not detected until the spinning stage of the last instar larva, however,it dramatically increased at the beginning of spinning and gradually decreased until pupal stage.

강민욱 한국웰니스학회 2019 한국웰니스학회지 Vol.14 No.3

The main concept of this study is to derive practical implications for encouraging the physical activity participation to disabilities by comparing the physical activity effect on the self–efficacy. Meta analysis was used as a research method to integrate the results of previous studies. The academic research on the subject was limited to the KCI(Korea Ciatation Index) listing research and meta-regression analysis based on CMA(Comprehensive Meta Analysis) was conducted. According to the data collection 133 studies were selected for the final data analysis. The results of this study are as follows. First, physical activity of the disabled and non–disabled had a positive influence on self–efficacy. Second, there was a difference in the effect of physical activity type on disabled. Third, verifying differences in the impact of physical activity on the self-efficacy of disabled suggests that the physical activity program to disabilities should take appropriate approaches. 본 연구의 주요 내용은 장애인과 비장애인의 신체활동참여가 자아효능감에 미치는 영향력을 검증가능한 객관적인 수치로 비교하여 장애인의 신체활동 참여를 권장하기 위한 실천적 함의를 도출하는 것이다. 이에 기존 연구결과를 통합하여 종합적 결론을 유도하기 위해 메타분석(Meta Analysis)을 연구방법으로 활용하였다. 장애인과 비장애인에 대한 학술연구는 한국학술지인용색인(Korea Ciatation Index) 등재지로 범위를 한정하였으며, 메타분석 방법인 CMA(Comprehensive Meta Analysis)에 근거한 메타회귀분석을 실시하였다. 통계패키지는 STATA 15.0 ver을 사용하였다. 자료수집 및 선정기준에 따라 1차 수집된 학술지 논문은 총 265개로 자료 선별 절차를 거쳐 133개의 선행연구를 최종 분석대상으로 선정하였다. 본 연구를 통해 도출된 결과는 다음과 같다. 첫째, 장애인과 비장애인 대상 신체활동은 자아효능감에 긍정적인 영향력을 미치는 것으로 나타났다. 둘째, 장애인과 비장애인 대상 신체활동 유형별 구분은 자아효능감에 미치는 영향력에 차이가 있는 것으로 나타났다. 셋째, 장애인과 비장애인 대상 신체활동이 자아효능감에 미치는 영향력 차이를 검증하는 것은 장애인의 신체활동 프로그램의 조직에 있어 이들의 특성이 반영된 적합한 방법으로의 접근을 해야 할 것을 의미한다.
