Current environmental education at elementary school is demanded to be changed into 'Sustainable Development', Therefore, we should find a new program to reflect appropriateness and diversity of environmental education at elementary school for 'Sustainable Development'. The result of analysing textbooks and the realities in environmental education at elementary school is as follows, First, when we analysed the contents of the textbook in environmental education, the reflecting rate was high in 'natural environment' and 'sound consumption', compared with in 'artificial environment', 'resource and energy' and 'health and environment'. Second, we realized the necessity for 'environmental education' complementary to 'Sustainable Development'. That is because the analysis showed the lack for the activity for approaching and solving environmental problems with 'artificial environment', 'resource and energy' and 'health and environment'. Third, the analysis also showed the deficiency in the reflection of 'environmental education' contents for maintaining healthful environment through improving the quality of life. Current textbook didn't deal with very important elements of 'environmental education' - the Quality of indoor atmosphere, harmful matter, safe things to eat, noise, stench, etc. For those reasons, it is necessary to reconstruct the realm and the contents of 'environmental education' for 'Sustainable Development' appropriate to elementary school. We require a new curriculum and textbook to cover diverse' environmental education' as well.

In order to preserve water environment, Total Maximum Daily Load(TMDL) is used to manage the total amount of pollutant from various sources, and the annual average load of source is calculated by the unit load method. Determination of the unit load requires reliable data accumulation and analysis based on a reasonable estimation method. In this study, we propose a revised unit load estimation method by analyzing the unit load calculation procedure of National Institute of Environment Research(NIER) method. Both methods were tested using observed runoff ratio and water quality data of rice paddy fields. The estimated values with the respective NIER and revised NIER methods were highly correlated each other. However, the Event Mean Concentration(EMC) and the runoff ratio considered in the NIER method appeared to be influenced by rainfall classes, and the difference in unit load increases as the runoff and EMC increase. The error can be further increased when the EMC and runoff ratio are changed according to changes in rainfall patterns by climate change and change of agricultural activities. Therefore, it is recommended to calculate unit load by applying the revised NIER method reflecting the non point pollution runoff characteristics for different rainfall classes.

The purpose of this study is the investigation and analysis of information on the conservation and the sustainable use of coastal wetlands based on the awareness of local residents in Suncheon Bay and Taeanhaean National Park. To accomplish the purpose of study, a questionnaire survey was chosen and the 98 valid samples(38 from Taeanhaean National Park and 60 from Suncheon Bay) among them were analyzed. The results are summarized as follows: The degree of the satisfaction on the natural environment is alike between Taeanhaean National Park and Suncheon-bay area. This is accorded with the order of the goodness of natural environment. The order for the degree of the satisfaction on the living environment is same as the order for the satisfaction degree on the natural environment. The residents of two regions are not satisfied with the socio·economic environment. The local resident of Suncheon Bay and Taeanhaean National Park Area where natural environment is well-conserved, prefer conservation to development of the region. These results show the following consideration for the ideal method of management for the conservation and sustainable development of coastal wetlands. In case of Suncheon Bay area, where the condition the natural environment is well conserved, should be managed with the minimum development with maintenance of the current state must be driven. In case of Taeanhaean National Park Area, where the condition of the natural environment is well conserved and the development potential exists, such as sustainable development and ecotourism destination the development that is in harmony with the nature must to be driven.

Recently, the importance of simulation validation in a virtual environment for autonomous driving system validation is increasing. At the same time, interest in the advancement of the virtual driving environment is also increasing. To develop autonomous driving technology, a simulation environment similar to the real-world environment is needed. For this reason, not only the road model is configured in the virtual driving environment, but also the driving environment configuration that includes the surrounding environments -traffic, object, etc- is necessary. In this article, FMTC, which is a test bed for autonomous vehicles, is implemented in a virtual environment and advanced to form a virtual driving environment similar to that of real FMTC. In addition, the similarity of the virtual driving environment is verified through comparative analysis with the real FMTC.

As the cloud-based ICT(Information & Communication Technology) infrastructure matures, the existing monolithic software development method is evolving into a micro-service structure based on cloud native computing. To develop and operate the services efficiently under the cloud native environment, DevOps-based application development plans through MSA(Micro Service Architecture) design based are essential. A cloud native environment is an approach to developing and running applications that take advantage of cloud computing models such as automation of source distribution, container-based virtualization, application scalability, resource efficiency, and flexible maintenance through object independence. To implement this approach, the utilization of key elements such as DevOps, continuous delivery, micro service, and containers is essential, but there are not enough previous studies on case analyses or application methods of these key elements. Therefore, in this paper, we analyze the cases of application development in cloud native environment and propose the optimized application development process and development method through small and medium-sized SI projects.

The objective of this study was to develop a Web based learning environment for Home Economics Education(HEE) using ICT (Information & Communication Technology). For the study, the following procedures were performed: 1) the review of literature, 2) development of teaming environment and questionnaires based on Web for HEE using ICT. The Web based learning environment was investigated and designed, and evaluated by the users. The problems indicated through the evaluation were revised and complemented. In addition, 13 sets of Learning questionnaires, which were verified using the same procedure as above, were developed to provide problem solving ability through the Web based learning environment. Learning environment based on the Web entitled "Together with the classroom of HEE" has a main menu, which is composed of rooms for HEE, students, teachers, various topics, recommendation sites, chatting, and e-mail. A room for HEE, in which teaming activity mainly occurs by following the sequences of learning procedures, includes other sub-rooms for the guidance of Loaming, discussion, directories for reference, question and answer, submission of homework, evaluation, and an encyclopedia. Therefore, this study implicates: 1) achievement of teaming environment using the ICT mainly made by students who solve problems closely related to daily life, 2) development of practical learning questionnaires fitted in the present state, 3) preparation for the curriculum. Finally, from this study, I suggested that further studies are needed to develop models for learning, interaction between students and teachers, and the learning materials under the Web based loaming environment.

This study aims to survey whether local governments have legislated laws and regulations on environment impact assessment system, to compare and analyze specific projects and their scale, assessment items, and procedures & discussion process, to identify issues and generate improvement plans, and to suggest a direction for future legislation to local governments that plan to legislate laws and regulations in the future. Major outcome of the study are as follows. First, terminologies used for environment impact assessment by local governments need to be unified. Also, laws and regulations need to be legislated soon. Second, in "urban development project" areas, a total of nine project areas including "quarrying of soil and stone, sand, gravel, and minerals" was essential common projects. A total of six project types were added or newly established compared to national systems. Among them, four project types were added within national-level project areas and two project types were not available under the national-level project areas and newly added due to the nature of local governments. Third, in terms of project scale, scale enhancement of "urban development project" was most common. Analysis showed that in case of clean natural environment such as Cheju Island, it is necessary to consider reinforcing project areas where development activities take place directly in forests or rivers such as "industrial base and complex development", "water resource development", and "development of tourism complex." Fourth, the discussion and review procedures of assessment reports were similar to those at government level. However, in case of Seoul city, it is required to write a "preparation plan" before drafting an assessment report. The city features partial introduction of scoping and screening, which allows to exempt discussion procedures if impact on environment is found to be minimal after drafting the assessment report. In case of national-level, it has a dual system that is split between Ministry of Construction and Transportation and Ministry of Environment. However, in case of environment impact assessment of local governments, it is a single system where city mayors and provincial governors are in charge of both project execution and environmental assessment. Therefore, the most important task is how to satisfy objectiveness and accountability.

Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were determined in marine sediments from Mokpo coastal water of Korea. Total and toxic equivalent (TEQ) concentrations of PCDD/Fs ranged from 19.4 to 175pg/g dry weight and ranged from 0.195 to 2.87 pg WHO-TEQ/g dry weight, respectively. These PCDD/F concentrations were below the safety sediment value (20 pg TEQ/g dry weight) of chronic toxicity. A highly significant correlation between the concentrations of PCDD/Fs and total organic carbon (TOC) in marine sediments was observed. Overall PCDD/F concentrations in the sediments were elevated in rivers and at inner locations close to harbors, indicating that these contaminants derived from local discharges of human activities. PCDD/F concentrations measured in our study were lower than those in several industrialized areas in Korea. Nonparametric multidimensional scaling (MDS) ordination showed that combustion processes from industrial complexes are the major source of PCDD/Fs in Mokpo coastal water.
