This study is the content about the development of ICT(Information and Communication Technology) teaching-learning model to support the korean language learning. Firstly, we proposed 3 types on developing models for ICT teaching-learning in korean language learning, we developed 4 ICT teaching-learning models based on analysing the curriculum of korean language course and studying the preceding works. Moreover we offered the strategies for applying ICT teaching-learning models with korean language learning. The developed 4 ICT teaching-learning models in this study are expected that ICT will use to design ICT teaching-learning model in another courses and teachers take advantage of the 4 models in korean lesson effectively.

The core strategy of transit oriented development (TOD) is to promote high density mixed land use around railway stations. Case studies in advanced countries show that provision of policies for comprehensive maintenance of pedestrian facilities around railway station spheres is being pursued with efficacy. In spite of the importance placed on integrated pedestrian maintenance, domestic construction of integrated pedestrian infrastructure around railway station spheres lacks direction. Thus, there is a clear need for an evaluation standard that can provide the foundation for judgments on TOD improvement. This research proposes a network model that consolidates the interior of the station as well as its surrounding areas to determine the ease of pedestrian flow for effective TOD evaluation. The model considers the railway station and surrounding areas as an assembled network of pedestrian flow. The path chosen by the pedestrian is defined as the optimal degree of inconvenience, and expands on Wardrop's User Equilibrium (1952). To assess the various circumstances that arise on pedestrian facilities including congestion of the pedestrian pathway, constrained elevator capacity, and wait at the crosswalk, a variational inequality based pedestrian equilibrium distribution model is introduced.

In mode choice decision, travelers consider not only travel time but also reliability of its modes. In this paper, reliability was expressed in terms of standard deviation and maximum delay that were measured based on triangular distribution. In order to estimate value of time and value of reliability, the Multinomial and Nested Logit models were used. The analysis results revealed that reliability is an important factor affecting mode choice decisions. Elasticity is used to estimate the impacts of the different policies and system improvements for water transportation mode. Among these policies, decision maker can assess and select the best alternative by doing the benefit and cost analysis based on a new market share, the value of time, and the value of reliability. Finally, a set of promising policies and system improvement of the water transportation were proposed.

화물 수송은 상품의 생산과 소비에 직결되어 있으며 원활한 화물 수송이 경제에 미치는 영향이 크므로 그 중요성이 날로 증대되고 있다. 우리 나라는 그 동인 지속적 경제 성장으로 인한 경제 규모가 확대되면서 화물 수송에 대한 수요가 급격히 증가하였다. 이러한 화물 수송 수요의 증가 추세에 비해 물류 단지의 확충에 위한 적절한 투자 및 정책 등이 결여되어 왔다. 그러므로, 경제 및 산업발전에 중요한 역할을 담당하고 있는 물류 단지를 파악하고 물류 단지 입지 결정 모형을 개발하고, 이 모형을 토대로 적정 입지를 결정하고자 한다. 물류 단지 입지에 관한 문제의 주요 관심 대상은 수송비용을 최소화하면서, 원하는 목적지까지의 빠른 수·배송을 이루어지게 하는 효율적 수송 입지 단지를 찾는데 있다. 따라서 본 연구에서는 물류 단지의 적정 위치 결정을 위하여 혼합 정수 모형을 이용해서 수송비용과 차량 경로를 고려한 수학적 모형을 개발하고자 한다. 개발된 모형을 공로부문의 수송을 중심으로 경기도 지역의 여러 물류 단지 후보 지역에 적용하고 적정 물류 단지를 찾고자 한다.

This study proposed a traffic accident prediction model developed based on administrative districts of Seoul. The model was to find the relationship between accident rates and the representative land usage of the districts (development density) - the higher the development density (building floor area) is, the higher the traffic accident rate is. The findings showed that traffic accident statistics differ from (1) residential building floor area, (2) commercial building floor area and (3) business building floor area.

This Paper aims to develop container terminal simulation models for medium and long term decision makings. It first undertakes in-depth survey of literature. finds its shortcomings and suggests some directions for improvement. It then proposes detailed design for the simulation models. Based on this it finally developes several simulation models and applies them to a hypothetical situation of a container terminal development. The results reveal that basic design questions such as length of quay, number of quay crane, size of storage area are well produced through the models.

In this study, a spatial location-allocation model of center villages (SLAMCV) was developed for selecting spatial center villages and allocating their rear villages. In SLAMCV, rural space was considered as a network with villages for nodes and roads for connecting lines. For quantification of residents’ accessibilities in the network, a disutility index (DUI) was developed and used, which is dependent upon travelling distance between the center and its hinter villages, design vehicle speed in connecting road and population of hinter villages. SLAMCV was verified to Christaller’s hexagonal hierachical settlement system to test the theoretical reasonability and computing algorithm of the model.

최근 IT기술의 발전은 교육의 패러다임을 변화시키는 중요한 요소로 작용하고 있다. 이러한 IT의 기술이 학습환경을 변화시키며 학습모형에도 영향을 미치고 있는 것이다. 특히 창의적인 생각이나 새로운 아이디어를 중요시 하는 국가적 교육 경쟁력이 핵심으로 작용하면서 창의력 증진을 위한 학습모형 개발 연구가 활발하게 진행되고 있다. 따라서 본 논문에서는 하나의 지식보다는 그룹의 지식이 강조되는 집단지성 기반의 창의력 증진 학습모형 개발에 대한 연구를 진행하였다. 기존의 학습모형은 교수자 중심적으로 지식을 전달하는 방식 이였다면, 본 연구에서는 교수자와 학습자, 참여자라는 집단의 생성과 학습 자료의 공유, 개방을 극대화 한 창의력 증진학습 모형을 제시하고자 한다. 또한 창의력 증진 학습모형을 위한 기술과 교육 그리고 소셜 네트워크의 통합적 적용 설계 모델을 제시한다.

The Internet is appearing a new paradigm called Web 2.0 which 'Participation', 'Sharing', 'Openness', 'Cooperation'. Web 2.0 is expanded by experts and general users and many people's ideas can solve more problems than an expert's idea. The collective intelligence is techniques that express the valuable of Web 2.0. For this reason, the collective intelligence has attracted attention because of its potential as an educational tool. The purpose of this study is to develop a PBL-based programming instruction model using collective intelligence to improve students' problem solving abilities and programming attitudes and verified its effectiveness. As a result, the developed instruction model showed significant differences in the students' problem solving abilities and programming attitudes. According to these results, these have been proved that a PBL-based programming instruction model using collective intelligence has an influence to the students' problem solving abilities and programming attitudes.
