Objectives: This study aims to examine receptor-perceived characteristics of environmental and health damage in areas surrounded by industrial workplaces using environmental complaints collected by local governments in Korea. Methods: The environmental complaint data related to workplaces was collected by local governments at each municipality between the years 2015 and 2017. We analyzed the complaint data from the Busan area by the type of business (industry classification), the content of complaints (odor, smoke, noise, and certain health damage), and the frequency of complaints. Results: Among the workplaces examined, industry categories related to retail and service received the highest frequency of complaints related to noise. On the other hand, complaints of dust and odors were raised in higher frequency against manufacturing industries, indicating that air pollution was the main driver of such complaints. Most of the complaints regarding health effects from industries also contained other complaints, such as odor, noise, and dust. Our results indicate that environmental discomfort can lead to more serious health damage, and should be dealt with more seriously. Further management plans for mitigating discomforts such as noise are necessary. Conclusion: This study can be used as background data for identifying the policy priorities related to vulnerable areas polluted by industry and will contribute to improving the environmental health of residents in identified areas.

The reasons for studying the case of Japan are as follows. First, the increases in the aged population is similar to the case of Korea, and consumers are aging as the population ages. Second, the structure of industry in Japan is very similar to Korea, which describes the fact that the share of the manufacturing industry decreases but the service industry (e.g., medicine, finance, and insurance) increases. Third, Japan is considered as the best predictive model for forecasting the future of closed schools in Korea because the GNI gross income per capita is relatively close to the one of Korea among the several neighboring countries. The purpose of this study is to analyze the current extent of utilizing closed schools in Japan and, based on the analysis, to provide basic data on the use of closed schools in Korea in the future. The types of closed schools can be classified into education facilities, social welfare facilities, cultural facilities, public sports facilities, income growing facilities, and others. Based on the classification, the analyses of the characteristics of each type for the facilities are presented. and When the utilization status of closed schools in Japan is analyzed, 363 schools were utilized (51.4%) in 2003, means the lowest utilization rate of the target year, after that 4198 schools (70.6%) were utilized in 2015. The utilization ratio is steady increased.

Chemical accidents are increasing day by day as the industry develops. To prevent such chemical accidents, Korea enacted the Chemicals Control Act. Through these laws, systematic management of chemical substances began. There are various positions in the companies. hazardous chemical supervisors, equipment and technical human, operators and employees. Chemicals-related education for each position should be provided. As a result of the survey, hazardous chemical supervisors and equipment and technical human liked the overall content of the Chemicals Control Act and the education subject on safety management standards for facilities. Conversely, the operators liked the course on how to wear personal protective equipment. The employees preferred subjects such as classification of chemical substances and prevention of chemical accidents. Currently, various modular textbooks are widely available. Rather than general education, it is necessary to select and provide customized subjects that are preferred and interested according to the position. Then it will be more effective in understanding harzardous chemical substances and in preventing chemical accidents.

It is very important to utilize effectively fibrous waste paper in terms of cost savings, environmental effects, and governmental policies. The quality of final products and runnability of papermaking process are primarily affected by constitutions of fibrous raw materials. In specific, board grade paper depends directly on compositions of waste paper bales. At present, the raw materials of board grade paper are mainly derived from lots kinds of wastepaper. Some papermaking countries, like EU, USA and Japan have advanced classification and management systems of recycled fiber, but Korea has not yet organized systematically. In this study, evaluation of wastepaper bale compositions and their fiber properties were carried out for effective utilization of fibrous raw materials for board grade paper production. 3 kinds of wastepaper bales were classified to fibrous or non-fibrous materials. In case of fibrous materials, KOCC, kraft sack paper and white duplex board matters were main component in total weight basis, and in case of non-fibrous materials, vinyl, plastic and cloth matters were main component, in turns. 3 representative kinds of waste paper were disintegrated and classified, and then prepared to handsheet for evaluation of recycled fiber property. Consequently, fines and ash content of waste paper, isolated from KOCC and white duplex board were higher than that of kraft sack paper. pH values of all kinds of waste fibers were neutral or weak alkaline.

The purpose of this study is to examine the spatial distributional characteristics of industries among the Korean cities and to conduct industry classification using the findings. For this purpose, 82 cities in Korea are investigated with respect to 15 industrial sectors. In the analysis, concentration of and association between industries are recognized using both geographic and non-geographic measures. In order to measure concentration and association, locational Gini coefficient, Moran's I, correlation coefficient, and bivatiate Moran are used and 15 industrial sectors are classified based on these estimates. The findings reveal that the chemical sector shows strong geographic and non-geographic concentrations while the assembly, machinery and electronics sector only shows a strong geographic concentration. Printing and publishing, wholesale, and business services show a strong non-geographic association with other sectors. The remaining ten sectors show no explicit distribution patterns among cities. This study contributes to providing the methodology that analyzes the spatial distribution patterns of industries in a comprehensive way and is able to provide useful information in implementing industrial location policies including industrial clusters.
