PURPOSES : This study aims to analyze the causes of pedestrian traffic accidents on community roads. METHODS : This study collected variables affecting pedestrian traffic accidents on community roads based on field surveys and analyzed them using negative binomial regression and zero-inflated negative binomial regression models. RESULTS : Model analysis results showed that the negative binomial regression model is more suitable than the zero-inflation negative binomial regression model. Additionally, the segment length (m), pedestrian volume (persons/15 min), traffic volume (numbers/15 min.), the extent of illegal parking, pedestrian-vehicle conflict ratio, and one-way traffic (one: residential, two: commercial) were found to influence pedestrian traffic accidents on community roads. Model fitness indicators, comparing actual values with predicted values, showed an MPB of 1.54, MAD of 2.57, and RMSE of 7.03. CONCLUSIONS : This study quantified the factors contributing to pedestrian traffic accidents on community roads by considering both static and dynamic elements. Instead of uniformly implementing measures, such as pedestrian priority zones and facility improvements on community roads, developing diverse strategies that consider various dynamic factors should be considered.

본 연구의 목적은 만학도로서 대학생활에서의 삶의 의미가 무엇인지를 알아보고 탐색해 보는데 있다. 연구대상은 서울·경기지역에 소재하고 있는 3∼4년제 재학생 6명으로 58세∼65세 연령의 만학도들이며 심층면담을 통해 자료를 수집하였다. 본 연구의 연구결과를 요약하고 논 의하면 다음과 같다. 첫째, [대학생활의 어려움]에 관한 주제군에서 <학과 수업에 대한 걱정>, <인간관계에서의 갈등>, <실습지 선정 및 실습의 두려움> 으로 주제가 분류되었다. 둘째, [대 학생활의 삶의 의미]에 관한 주제군에서 <자신감 향상>, <자아실현>, <비전제시>로 주제가 분류되었다. 만학도들은 공부를 못했다는 한(恨)에서 시작하는 학생이 대부분이었지만, 대학생활을 통해 자아실현이 이루어지고 있었으며, 함께 공부를 하고 있는 학생들에게 귀감이 되고 있다는 것도 함께 발견할 수 있었다. 하지만 만학도들이 대학생활에 잘 적응하고 졸업 후 사회에 나와서 도 전공한 것을 사용할 수 있도록 이들을 지원할 수 있는 구체적인 프로그램이나 매뉴얼 등에 대한 연구가 활발하게 이루어져야 할 것이다. 본 연구 결과는 보육관련학과에 재학 중인 만학도들의 대학생활 지원방안에 필요한 기초자료를 제공할 것으로 기대된다.

This study was to investigate the association among satisfaction of nutrition labeling, change of purchase behaviors, and dietary life care, based on the awareness of nutrition labeling at expressway rest areas. The subjects (n=903) were divided into two groups, according to the awareness of nutrition labeling: Awareness of Nutrition Labeling (ANL) group, n=367; Non Awareness of Nutrition Labeling (NANL) group, n=536. Effort of health care and identification of nutrition labeling was significantly higher in the ANL group, compared with the NANL group. As for the main reason for not identifying nutrition labeling, ‘not interested in nutrition labeling’ was the highest in the ANL group, and ‘Don't know nutrition labeling is provided’ in the NANL group. Identification ratio of nutrition labeling in future was significantly higher in the NANL group, compared with the ANL group among the subjects who didn't identify nutrition labeling before. After their becoming aware, a change of food purchase after reading the nutrition labeling was significantly higher in the ANL group, compared with the NANL group. Health beliefs on the nutrition labeling were significantly higher in the ANL group, compared with the NANL group. Satisfaction of nutrition labeling was also significantly higher in the ANL group, compared with the NANL group. The ANL group also expressed a necessity of expansion of nutrition labeling, compared with the NANL group. In the ANL group, identification of nutrition labeling was significantly higher in the hard effort group, compared with the little effort group of dietary life care. Therefore, improvement and campaign of nutrition labeling for consumers at expressway rest areas, especially for the NANL group, will be effective in identifying nutrition labeling for their health care.

본 연구는 생활도로 속도관리 방안으로 선진국에서 추진되고 있는 Zone 30 제도를 우리나라의 도로 및 교통여건에 맞게 도입하고, 시범운영을 통해 시행의 효과를 분석하는 동시에 시행상의 문제점을 분석하여 향후 제도 확산을 사전에 대비하고자 하였다. 시범운영지역으로 선정된 곳은 경찰청 T/F에서 현장 조사 및 전문가 의견을 수렴하여 상가 밀집지역 주변도로 중 편도 2차로 이내의 도로이며, 보행자 통행량이 많고 보행자 사고율 또는 위험성이 높은 경기 고양시 일산구 장항2동 (면적 0.65km2)이다. 우선 Zone 30 제도 검토 측면에서 생활도로와 생활도로구역의 용어를 정의하고, 생활도로 유형화 및 운영방안을 수립하였으며, 시범사업은 대상지에 대한 정밀 조사를 통해 문제점 및 개선점을 도출하고, 그에 따른 시설개선도면을 작성하여 해당 지자체와 협의하여 시설을 설치완료하였다. 시설 설치 전과 후로 나누어 효과분석을 수행한 결과 차량 속도는 시행전에 비해 가로별로 5~15km/h 감소하였으며, 교통사고의 경우도 시행전 25건에서 시행후 19건으로 24%가 감소한 것으로 나타났다. 또한 속도관리 사업의 시행과정이 빠르고 시설비용이 저렴해 전국적인 확산시행이 유리하여 보행자사고 감소에 실질적 기여가 가능한 것으로 나타났다. 시범사업 연구결과를 토대로 생활도로구역 속도관리 사업추진 방안 등을 제시하였다.

Recycling of incineration ash generated from domestic waste incinerators is important from environmental and energy conversation aspects. The main components of bottom ash are CaO, Al2O3, SiO2, P2O5, MgO, and Fe2O3, similar to geological components. However, it also contains heavy metal ions such as Cu2+, Pb2+, and Cr6+. The ash material was sintered at 1100 ~ 1150oC by adding pink kaolin to stabilize those heavy metals. The study analyzed the crystal phase and absorption rates of the sintered material for application as a sub-base layer material for roads and conducted tests for the requirements for sub-base layer materials for roads, such as CBR test, quantity of abrasion, and liquid limit. Considering the plasticity, water absorption, and compressive strength of the road base, the mixture with 76wt% bottom ash and 24wt% pink kaolin after sintering at 1,120oC, showed CBR test result of 33.0, quantity of abrasion of 30.3, and liquid limit of NP (no plasticity). These result indicated the possibility of using bottom ash as a sub-base layer material, which satisfied requirements of the standard specification for road construction.

This study was carried out to analyze the disparities of basic living infrastructure between Guns(rural counties), and between Eups/Myuns(rural districts) in Jeollanam-do province. For the purpose of this study, dimensions of regional disparity in basic living structure were measured by 3 components ; road, public water service and sewage disposal. By utilizing the published statistics, this study has examined 8 Guns(counties) containing Eup and Myon in Jeollanam-do province which can represent 4 different rural areal types, respectively, i,e. mountainous, semi-mountainous, flat and seashore areas. The data acquisition time of this study is fixed on end of 2009 year in order for possible collections of the most recent published statistics. It presents evidence on the magnitude and evolution of discussion of regional disparities between Guns(counties), and between Eup & Myon, and between Myons in Jeollanam-do province even though infrastructure provision level of Jeollanam-do rural areas are much more improved than the past. Concludingly, the existing disparities in this area is meaningful and so, it should be seriously reconsidered when deciding local government's budget allocation priority.
