With changing to the new information technology society, education has also been urged to utilize the Information Ccmmunication Technology(ICT). Thanks to the recent efforts by the government, a large number of schools has been equipped with advanced educational technologies. While there has been a lot of studies on how to use ICT more effectively, relatively few is the studies about the activating factors of ICT utilization. More than often than not, those studies have been conducted about the survey of current situations of ICT utilization and have never had implemented based on the theory of diffusion of innovation. As a result, the current study surveyed the previous studies about encouraging and resistance factors of ICT utilization in light of the theory of diffusion of innovation and environmental encouraging factors by Ely. Then, the efforts were made to present suggestions to encourage the utilization of ICT in schools.

This study deals with the roundabout traffic accidents by traffic impeding factor. The purpose of this study is to comparatively analyze the characteristics of accidents and to develop the accident models. In pursuing the above, this study used a statistical program SPSS 20.0 to analyze 2,342 accidents occurred within 79 roundabouts in Korea. The main results are as follows. First, 4 accident models which were all statistically significant were developed. Second, the traffic volume and width of right-turn-only lane were analyzed to be common variable in the bus stop related models. The variables such as right-turn-only lane, street light, turning radius of entry lane were selected as specific variables. Especially street light and turning radius of entry lane were evaluated to have negative effects to the accidents. It is, therefore, essential to install the street light and place a sufficient turning radius in order to reduce the roundabout accidents. Finally, the traffic volume and number of entry lane were analyzed to be common variable in the on-street parking related models. Also, the width of right-turn-only lane and bus stop were evaluate to be specific variables in the model with on-street parking. This can be expected to give some implications to making the accident reduction guidelines.

This study deals with the traffic accidents of arterial road. The objectives are to analyze the relationships between the accidents and V/C ratio, and to develop the accident models using Tobit model. This study uses the data of 2,004 accidents occurred on 24 arterial roads in 2008 to 2010. The main results are as follows. First, the relations between number of accidents and V/C ratio are analyzed to be the quadratic functions. Second, 2 accident models are developed using Tobit model, which are all evaluated to be statistically significant. Finally, V/C ratio, number of entrances, number of curves and exclusive left-turn lane whether as common variables, and rate of median, number of pedestrian crossings, number of bus stops, and exclusive right-turn lane whether as specific variables of the models are selected.

This study deals with the left-turn treatments of intersection. The goal of this study is to comparatively analyze the effectiveness of various treatments. In pursuing the above, this study gives particular attentions to simulating the delay of such the treatments as protected left-turn, P-turn, U-turn and roundabout using VISSIM software. The main results are as follows. First, in 4-leg/2-lane intersection, roundabout under 800veh./h and P-turn over 900veh./h are analyzed to be the best treatments. Second, in 4-leg/3-lane intersection, the analyses show that protected left-turn is the worst and U-turn is the best treatment. Finally, in the higher left-turn ratio, U-turn and P-turn treatments are analyzed to be better than protected left-turn.

This study deals with the relations between nonphysical urban characteristics and traffic accidents in case of Cheongju. The goal is to develop the count data models which explain the accident factors by zone. In pursuing the above, the pedestrian accident data from 2007 to 2011 are collected from TAAS data set of Road Traffic Authority. The main results are as follows. First, a negative binomial model which is statistically significant (P^{2} value of 0.252) is developed. Second, the adopted independent variables are analyzed to be total population, internal trip ratio and elderly person ratio.

이 연구는 TAAS 자료를 이용하여 고령운전자의 삼고심각도를 다루고 있다. 이 연구는 문헌조사를 통해 주요 변수 들을 선택하고, 순서형 로짓모형을 이용하여 사고요인을 분석하는데 중점을 두고 있다. 연구의 주요굘과는 다음과 같다. 첫째, 사고심각도는 차량과 포장 유형에 의해 영향을 받는 것으로 분석된다. 둘째, 흐린 날과 여름철의 사고 심각도가 높아지는 것으로 평가된다. This study deals with the traffic accident severity of elderly drivers using TAAS``s data. The study gives particular attentions to choosing main variables through literature survey, and analyzing the accident factors using the ordered logit models. Main results are as follows. First, the accident severity is analyzed to be influenced by vehicle and pavement. types. Second, the severity is evaluated to be high in cloudy day and summer. This study is expected to give some implication to making traffic safety strategies.

This study has been focused on the evaluation of domestic softwood timbers to replace imported timbers for woodcrafts and furniture-making. Figures on radial and tangential sections were observed with naked eyes. As the result of study on the figures appeared on the wood surface of 6 species of trees, flat grain and edge grain were clearly found from Taxus cuspidata. Juniperus chinensis and Ginkgo biloba had wavy grain figure and pigment figure, and blister figure was found in Pinus densiflora, Larix kaempferi showed pitch streak and irregular figures on its tangential section due to growth abnormalities. Wavy grain figure appeared weakly on near knot of Pinus koraiensis. The characteristic figures shown from each species of trees are expected to be used for crafts, sculptures, furniture, and interior decoration. They are also considered to have great potential to substitute imported timber sufficiently, which are currently used a lot for wood crafts and furniture-making.
