This study tested students’ ICT application capability and Problems solving ability by ICT instructional environment when ICT teaching method is applied to $\boxDr$Understanding of Myself and Family$\boxUl$ unit of home economics. Following research Problems were formulated for this study : 1. Are there any differences of the effects on improvements of students’ ICT application capability by ICT instructional environment\ulcorner 2. Are there any differences of effects on improvements of students’ problems solving ability by ICT instructional environment\ulcorner 3. Are there any differences of effects on improvements of students’ Performance assessment results by ICT instructional environment\ulcorner The researcher developed a homepage for the ICT teaching-learning. and prepared Problems-based teaching-learning lesson plan. The students were divided into two groups (experimental group 1 and experimental group 2) by ICT instructional environment. The Pre-test and post-test were conducted before and after the experimental class. The ICT class experimental period was for 16 weeks. from March 10. 2002 to July 10. 2002. The experimental group 1 was given 16-weeks classwork under the classroom environment of 1 PC for each classroom(The classroom with advanced educational equipments) . while the experimental group 2 was given 16-weeks classwork under the classroom environment of 1 PC for each student(multimedia classroom) . The results of the study are as follows: 1 All of the ICT teaching methods under both instructional environments were found to be effective on the improvements of the ICT application capability. 2. There were statistically significant differences of problems solving ability between two groups in application and the measure of validation. 3. The experimental group 1(1 PC for each classroom) did not show any improvements of Performance assessment results. while the experimental group 2(1 PC for each student) showed some improvements.

This study aims to analysis the curriculum problems and its improvements and to investigate curricula satisfaction among the students majoring in Clinical Pathology. A college used as a population, and 80 effective survey data were collected by sampling the graduates who carried out the clinical field training in third grade year. For statistical analysis of the collected data, the Stata(version 12.0) statistical package was used for frequency analysis, pearson correlations test and multiple regression analysis. The results of the analysis were as follows; First, the result showed that the synthetical theory curriculum has an positive effect on curricula satisfaction. Second, it was found that extension of both the clinical field training and laboratory and practice education have an significant influence direction of positiveness on curricula satisfaction. Third, as the problems of curriculum, the students selected shortage of english subjects connected with the job. We must intensify additional subjects (english ability) for job as the improvement of curriculum. Accordingly, academic, industrial circles and students are supposed to jointly seek for the plan for the enhancement of clinical field training satisfaction.

This study intends to analysis problems and propose of EIA(Environmental Impact Assessment) and PER(Pre-Environmental Review) especially on division of landscape impacts. The problems of EIA and PER are first, on analysis of existing conditions side, insufficiency of the list of landscape elements and their descriptions and presentations, and the number of viewpoints and each validity second, on estimation of landscape impacts, the methods and techniques of estimation and simulation, and the process of impact estimation, third, on suggestion of reduction plans, reduction devices covering impacts, the lack of influence reduction forecasting devices, the deficiency of execution power of reduction plans, finally, the systematic connection of impact estimation with existing conditions analysis and reduction plans. Therefore, on each step from existing condition analysis to reduction plan suggestion, the solutions to each problem are proposed.

In the Port Logistics system, Container Stowage planning is an important issue for cost-effective efficiency improvements. At present, Planners are mainly carrying out Stowage planning by manual or semi-automatically. However, as the trend of super-large container ships continues, it is difficult to calculate an efficient Stowage plan with manpower. With the recent rapid development of artificial intelligence-related technologies, many studies have been conducted to apply enhanced learning to optimization problems. Accordingly, in this paper, we intend to develop and present a Deep Q-Learning Network model for the Master Stowage planning of Container ships.

Recently, a massive loss of life and property is occurring in Korea due to traffic accidents, with the rapid increase in cars. For improvement of traffic safety, the Korea Transportation Safety Authority intensively analyzes accident data in local governments with low traffic safety index, performs a field investigation to extract problems and offers local governments improvements for problems, by conducting the 'Special Survey of Actual Conditions of Traffic Safety' each year, starting 2008. But local governments cannot strongly push forward the improvement projects due to the limited budget and the uncertainty of the improvement plan effects. Therefore, this study suggested a model which applied the Utility concept to the AHP theory, in order to efficiently decide a priority of the improvement plans in accident black spots in consideration of the limited budget of local governments. The number of accidents in each spot for improvement and accident severity, traffic volume, pedestrian volume, the improvement project cost and the accident reduction effect were chosen as evaluation factors for deciding a priority, and data about the improvement plan costs and the accident reduction effects, traffic accidents and traffic volume in the spots to undergo the special research on the real condition of traffic accident in the past were collected from the existing studies. Then, regression analysis was carried out and the Utility Curve of each evaluation factor was computed. Based on the AHP analysis findings, this study devised a priority decision method which calculated the weight and the utility function of each evaluation factor and compared the total utility values. The AHP analysis findings showed that among the evaluation factors, accident severity had the biggest importance and it was followed by the improvement plan cost, the number of accidents, the improvement effect, traffic volume and pedestrian volume. The calculated utility function shows a rise in utility, as the variables of the 5 evaluation factors; the number of accidents, accident severity, the improvement plan effect, traffic volume and pedestrian volume increase and a fall in utility, as the variables of the improvement plan cost increase, since the improvement plan cost is included in the budget spent by a local government.

The materials, parts, and equipment industries are the backbone of the manufacturing industry and a key element of competitiveness. However, in the case of Korea, as it relies on foreign countries for core materials, parts, and equipment, it is in danger of not only industrial competitiveness, but also security. This study first looked at the outline and current address of the materials, parts, and equipment industries, identified problems and improvements, and examined the efforts and achievements so far for the localization of materials, parts, and equipment in Korea. In addition, after looking at the improvement measures for the government's material, parts, and equipment industry at the institutional level or at the ecological level, the current status and actual condition of localization of local materials, parts and equipment were investigated, and problems and improvements were analyzed. Lastly, this study presented a technology development plan for localization of parts and materials in the region and various institutional improvement plans related to commercialization.

Plant industry is very important industry that dominate 70% of standard foreign countries construction acceptance an order woe 2004 years. Technique of plant industry is state that secure part equipment connection detailed design and construction class' competitive power. But, high added value creation among plant industry need technique elevation because available plan, basic design technology is insufficient. Therefore, high added value creation wishes to present problem of standard code and improvement direction for plant design to improve available plan, basic design technology competitive power.
