This study reflects the aim of analyzing the fashion design connection with ecology. Ecology has been linked to human life through its changing relations with environment. In order to recover eco-system ecology-nature oriented methodology and technology oriented approach will suffice. On the modern design field Green design Recycling and Green marketing resulted in increasing rates of environment-friendly production and an effort to deliver environment-friendly corporate image. Based on above research ecological image on fashion design during the year 1990 to 1995 represents the following conclusion. In the fashion design field natural image primitive image nature -harmonious image material-recyling image culture-recycling image are proposed. In the technology field clean image and high-tech image are proposed. In the marketing field happy image harmonious image serious image and realistic image are proposed.

complexity in atmospheric environment coupled with shoreline and complex terrain often causes local variations of meteorology that are distinct from those representative over larger surrounding area, These kinds of local variations are less significant in usual long-term environmental impact analyses dealing with continuous plume. The variations could however be crucial in predicting dispersion of toxic substance released in a relatively small area for a short duration. In the present paper the effects of spatial and temporal resolution of diagnostic wind field on the dispersion of the released substance are investigated by using a puff model. A hypothetical release scenario assumes that a substance is released from a location in the Yochon Industrial Estate and passively dispersed within a few-kilometer distance for an hour. The results show that diagnostic analysis could resolve more spatial variations to some extent by employing smaller grid size. The peak concentrations and puff trajectories obtained from spatially -and/or tmeporally -varing diagnostic wind field are found appreciably different from those obtained from uniform wind field. Attention to high-resolution wind field in the both spatial and temporal spaces is called in the consequence analysis of toxic substance release.

Recently with the demand of well-being is increased, the demand for indoor thermal environment and air quality is increased. According to this circumstance, many people in Korea note the traditional architecture that is made by natural materials, such as a soil, stone and wood. However, few researches regarding the indoor thermal environmental characteristics of the Korean traditional houses is reported. In this study we analyzed the indoor thermal environment for Han-ok through field measurement. Moreover, based on the field measurement results. indoor thermal comfort in Han-ok is analyzed.

The core of the change in the era of the 4th industrial revolution is the change in the base of 'digital technology'. These changes are incomparably large and are expected to have a more important impact on our lives than ever before. One of the major inflection points in the transition to the digital era is the education field, and IT technology has become an essential element in the educational field. Accordingly, this study examines domestic research trends related to the educational environment based on digital technology. Then, we would like to provide implications for the establishment of a digital-based educational environment that will change in the future. To this end, Semantic network analysis has been conducted to quantitatively structure text data obtained from studies related to digital technology in the field of mathematics education over the past 10 years, and the discussion will continue based on the results.

The Journal of Astronomy and Space Sciences (JASS) has published research papers on a range of topics since its initial publication in 1984, giving space science researchers a platform. In this paper, we reviewed recent publications (2019-2023) that deal with the space environment. In the space environment field, we reviewed 37 papers published in JASS during this time, covering research topics such as the sun, magnetosphere, ionosphere, atmosphere, and space radiation. We hope that researchers in the field will make use of this in the future as it will allow us to share the most recent trends in the field of space environment research that is currently underway.

Environment education, which is a principal solution to environmental problems in the world, is being practiced in Korea through the national curricula for primary and secondary schools. However, it hasn't been effective so far to practice environment education within those schools where a variety of subjects are taught. The purpose of this study is to look for the possibility of practicing environment education and thereby to make some suggestions for effective environment education in the field of English education, which doesn't seem to have a close relationship with environment education. This study first specified prospective contents of environment education by analyzing the Seventh National English Curriculum. Then, on the basis of them, the study explored how to practice environment education in the field of English education. Finally, for effective environment education, it made some suggestions and emphasized the importance of consistent efforts.

Background: Education on environmental health in Korea was begun with establishment of the Graduate School of Public Health at Seoul National University 1959. The sanitary movement started in Europe and the Americas in the 19th century and was introduced to Korea in the 1960s under the name of sanitary engineering. The field enlarged along with title changes. Objectives: The purpose of this study was to investigate the previous and present status of the environmental and public health fields in Korea. Methods: This study utilized documents published by the South Korean Ministry of Education and Korean Education Development Institute (KEDI) from 2015 to 2020, the homepages of universities with their history and regulations, and other related published documents. Results: Public health was fundamentally enlarged as an expert field in Korea with the establishment of the Graduate School of Public Health at Seoul National University in 1959. There are 102 departments relevant to the environmental field at two-year colleges, 220 at universities, and 175 at graduate schools. There are 89 departments relevant to the public health field at colleges, 96 at universities, and 160 at graduate schools as of 2020. The term "environment" in the title of a department is used as much as 80~93.1%, but "public health" in titles is used in 47.7~61.5%. Fifty percent of graduate schools of public health award specialty degrees other than master of public health. Conclusions: Although environment and public health fields have been expanded in universities in Korea, various specialty fields were included in university and graduate school. It is important to consider the coping plan with the trend.

This study area has been contaminated by oils. To identify contaminated ranges and to assess the possibility of contamination dispersion, monitoring wells were installed and slug test, field soil permeability test, automatic or manual measurement of groundwater table, and groundwater quality analyses in field and laboratory were performed. In addition, a groundwater modeling program was used to assess the possibility of oil contamination dispersion, based on field data and groundwater quality data. The results showed that concentration of oil contaminants in groundwater have been decreased by dispersion and adsorption.

In this paper, potential field algorithm was used for path planning in dynamic environment. This algorithm is used to plan a robot path because of its elegant mathematical analysis and simplicity. However, there are some problems. The problems are problem of collision risk, problem of avoidance path, problem of time consumption. In order to solve these problems, we fused potential field with fuzzy system. The input of the fuzzy system is set using relative velocity and location of robot and obstacle. The output of the fuzzy system is set using the weighting factor of repulsive potential function. The potential field algorithm is improved by using fuzzy potential field algorithm and, path planning in various environment has been done.
