The purpose of this study is twofold. First, this paper argues that a theoretical lens that can connect three crucial concepts is often missing when it comes to assessing the success or failure of corporate reputation in terms of corporate environmental responsibility. These three concepts include the legitimacy of environmental disclosure information, stakeholder interest in corporate environmental responsibility, and the relationship between corporate environmental practices and disclosure. The second purpose is to investigate the roles of transparency and systemic thinking in corporate environmental responsibility and disclosure that could help to connect the information from environmental disclosure to internal information in firms, thereby minimizing conflicting accountabilities and increasing stakeholder engagement in environmental disclosure. Rather than conducting an empirical study, the author has followed a theoretical examination of legitimacy, stakeholder, and stewardship theories. This study, thus, suggests the retention of many theories (e.g. legitimacy, stakeholder, and stewardship) to study and explain the relationship of corporate environmental practices, environmental disclosure, and corporate reputation.

The purpose of the article is to evaluate the factors that affect the degree of environmental accounting information disclosure. Data are collected from 87 industry companies listed on the Vietnamese stock market from 2009 to 2019. I focus on the effect of factors such as the Firm size, Profitability, Leverage, Firm age, and Independent auditors. To explain the causal relationship between factors, I construct the regression model and then test it by using different statistical method approaches, including the pooled OLS, the fixed effects model, and the random effects model. Then I conduct testing of model defects: White Test, Wooldridge Test, Hausman Test, and Wald Test. The Feasible Generalized Least Squares (FGLS) method is used to analyze the image factors that affect environmental accounting information disclosure. The results show that the extent of environmental accounting information disclosure is influenced by factors: firm size, uptime and independent audit. These factors positively affect the level of environmental accounting information disclosure; independent audit has the greatest influence. Based on the research results, the author gives recommendations to improve the disclosure of environmental accounting information for industrial enterprises listed on the Vietnamese stock market, increasing the competitiveness of the public company in terms of global integration.

산불은 오랜 기간동안 사회 및 경제적으로 지구에 많은 피해를 야기하며, 이러한 산불은 자연적 혹은 인위적으로 발생되어왔다. 이로 인해 여러 실험들에서 산불로 인한 악영향에 관한 연구들을 진행하였으며, 동시에 산불 발생 시 빠른 대처를 위한 산불탐지 및 오염배출 물질 탐지 등과 같은 연구들도 수행되었다. 그러나 현재까지 한국 및 동아시아 영역을 배경으로 한 연구는 부족한 실정이고 산불 탐지에 활용되는 자료들의 정확도에 한계가 있었다. 본 연구에서는 정지궤도 환경위성(Geostationary Environment Monitoring Spectrometer, GEMS) 영상에 위색합성기법을 활용해 새로운 산불연기 탐지 산출물을 생성하고 해당 영상을 U-Net 모델링에 활용해 기존의 연구들에서 산불 탐지시에 활용했던 가시광선 채널 영상의 한계를 보완하였다. 그리고 U-Net 모델링을 통해 산출된 산불연기 영역으로부터 황사 픽셀 필터링을 수행하는 분류모델을 구축하여 순수 산불연기 탐지 영상을 산출하였으며, 이는 GEMS 기반의 재난감시에 활용될 수 있을 것으로 기대한다.

This study was carried out to lead the scientific management of the urban forest by estimating the forest environment. Forest environmental information was constructed using IDRISI system based on survey data, soil, plant, and digital elevation data. Forest environmental information was consisted of soil depth, soil organic content, soil hardness and parent rock as a soil environmental factor, and forest community, tree age, crown density as a plant environmental factor. Plant activity and topographic environment also were analyzed by using remote sensing data and digital elevation data. Environmental function of urban forest was estimated based on results of soil conservation and forest productivity. 70% of urban forest is located in elevation of lower than 200m and 55% of forest area have the slope of lower than 15 degree. Analyzed soil conservation status and forest productivity were almost the same as the soil chemical properties of collected soil sample and the vegetation index estimated using remote sensing data, respectively. Thus, the constructed forest environmental information could be useful to give some ideas for management of urban forest ecosystem and establishment of environmental conservation planning, including forests, in Taejon. The best forest environmental function was appeared at the natural ecology preservation zone. Current natural parks and urban parks were appeared to establish the environmental conservation plan for further development. The worst forest environmental function was appeared at the forest near to the industrial area and an overall and systematic plan was required for the soil management and high forest productivity because these forest was developing a severe soil acidification and having a low forest productivity.

Environmental conservation planning as set forth in the "Framework Act for Environmental Policy" is a representative planning that demands linkages with spatial development planning like urban master plan. However, despite the intentions and efforts of government (including revision of relevant guidelines etc.), controversy still continues regarding the efficacy of environmental conservation planning in respect of its linkages to spatial development planning. Accordingly, this study was devised to examine existing issues and produce proposals for improvement in ensuring the efficacy of environmental conservation planning by local governments. This study focused in particular on the establishment of spatial environmental plans as suggested in the guidelines of the Ministry of Environment for the purposes of strengthening the efficacy of environmental conservation planning. Based of questionnaires for relevant officials of local governments, the study found that although local governments with established current spatial environmental plans are not numerous, the need for establishment of spatial environmental plans were high in terms of the applicability of environmental conservation and spatial plans. Furthermore, this study also confirmed through analysis of questionnaires data, archival research and case study research that there were a number of salient issues including an overly access and program centered planning method based on individual pollution sources and individual post factor measures in the planning aspect, a lack of usable spatial information in the application of spatial environmental information, and inadequate connections with spatial development planning in respect of linkages with other plans. Under these circumstances, various proposals for improvement were presented including the establishment of contents in environmental conservation planning for each urban master planning item from the standpoint of planning, strengthening of basic environmental surveys for spatial planning and preparation of applicable proposals from the perspective of leveraging of spatial environmental information, and systematic improvements that can enable mutual consideration through feedback between environmental conservation planning and urban master planning from the perspective of connections with spatial planning.

In order for a mobile robot to move under unknown or uncertain environment, it must have an environmental information. In collecting environmental information, the mobile robot can use various sensors. In case of using ultrasonic sensors to collect an environmental information, it is able to comprise a low-cost environmental recognition system compared with using other sensors such as vision and laser range-finder. This paper proposes a map building algorithm which can collect environmental information using ultrasonic sensors. And also this paper suggests a traveling algorithm using environmental information which leads to the map building algorithm. In order to accomplish the proposed traveling algorithm, this paper additionally discusses a position revision algorithm.

The purposes of this study was to examine the effects of demographics, environmental attitude, environmental behavior, exposure to environmental information, and motives of clothing disposition on clothing disposal behavior. Data were obtained from questionnaires filled out by 217 women in Taegu and were analyzed by utilizing factor analysis, correlation analysis, and stepwise regression analysis. The results indicated that clothing disposal behavior was influenced by predicted variables such as education, exposure to environmental information, environmental attitude, and environmental behavior. Among predicted variables, the environmental attitude was the most important variable affecting clothing disposal behaivor. However, the proportion of variation in clothing disposal behavior that was explained by predicted variables was relatively low.
