우리 사회는 1970년대 이후 급속한 공업화와 대도시 인구 집중을 겪어왔다. 공업화는 필연적으로 대기오염배출시설의 증가를 가져왔고 도시의 인구집중은 연료의 사용과 자동차의 증가를 가져와 이들 지역의 대기오염을 증가시켰다. 이에 따라 대기오염배출시설을 관리하고 주변 지역의 영향을 분석하며 도시의 대기질을 개선하기 위하여 우리나라에서도 1970년대 후반부터 대기오염 모델들이 이용되기 시작하였다. 우리나라에서 이 분야에 대한 연구와 활용은 외국에 비하여 늦게 시작되었지만 지난 15년간 대기오염모델은 많은 분야에서 활용되어 왔고 연구도 점차 활발하여 지고 있다.

최근 황사는 지구온난화와 토양의 사막화 등에 의해 발원지가 계속 확대되고 발생빈도 역시 증가하고 있으며 서해안에 인접한 중국의 북동부 공업지역에서 방출되는 오염물질까지 황사에 실려와 심각한 국내의 오염 문제 및 국제 문제로 부각되고 있다. 이들 대기오염물질은 가스상과 입자상으로 구분할 수 있는데, 요즘 입자상 물질의 건성침적량에 관한 연구가 서서히 활기를 띄어가고 있다. 입자의 크기가 0.1-10$\mu\textrm{m}$에 달하면 장거리 이동이 가능하며, 시정악화는 물론 흑비를 내리고, 인체에는 기관지 질환을 유발하기도 한다.

코로나바이러스감염증-19(COVID-19)의 확산 추세로 한국뿐만 아닌 전 세계적으로 여행 횟수의 빈도가 낮아짐에 따라 각 지역의 소상공인들은 매출의 큰 타격을 입었다. 본 연구에서는 사용자들의 여행 경험을 기록하고 공유하는 시스템을 개발하였다. 코로나바이러스감염증-19(COVID-19)의 종식 이후 다양한 사용자들의 여행 경험을 공유하고 이를 바탕으로 여행지를 추천하고 정보를 공유하여 지역 경제의 활성화를 이끌어 낼 수 있을 것으로 기대된다.

For a total of 210 city and Kun areas in Korea, a model was developed to predict the amount of groundwater use at each area. At first, the total areas were classified into 3 groups by the characteristics of groundwater use: residential(87), industrial(27) and agricultural (96) areas. Among them, type areas, represented by the dominant groundwater usage for typical purposes, were selected: residential(22), industrial(8) and agricultural(32) areas. Data for the various factors possibly related to the groundwater use were statistically analyzed. The factors include, 1) agricultural area, 2) industrial area, 3) adininistrative unit area(city or Kun), 4) population, 5) groundwater capadty for community water supply, 6) average water supply for a person per day, 7) agricultural water-use, 8) industrial water-use, 9) residential wateruse, 10) rates of community water supply. The data were correlated to the total amount of groundwater use, and the correlations tested at the 95% and 99% significance levels. Influential, significantly related, factors were identified from the tests. Using the multiple regression method with the influential factors, predictive equations were drawn to calculate the amount of groundwater use for residential-industrial and agricultural areas, respectively. The equations were calibrated to minimize the RMS(root mean square) of the differences between predicted and observed groundwater use. After the validation with future data, the model can be utilized in the regional development plans to predict the maximum groundwater demand at each area.

The concentrations in women's hair of essential and toxic elements such as Zn, Ni, Fe, Mn, Cu, Cr, Pb and Cd in residential and factory areas in Pusan were determined, and all the elements were detected from all the samples. It was apparent that employees working in factory areas in Pusan were exposed directly to the essential and toxic heavy matals. This is based on the fact that average concentrations of Ni, Fe, Mn, Cu, Cr, Pb, and Cd in hair samples from women aged 10 to 29 in factory area, who were considered to be main members among women employees, were much higher than those of residential areas. That is, the highest concentrations found in the hair samples taken from women 10 to 29 years old living in factory areas were 110 times higher in Cr (in the women in their 20's), 92 times higher in Pb (in the women in their teens) and 23 times higher in Cd (in the women in their 20's) than those living in residential areas. Furthermore, it was suggested that the heavy metals may be accumulated gradually in human bodies as humans get older, based on the fact that the concentrations of Cr, Pb, and Cd in women living in residential areas were higher in older age groups, although the average contents of these elements in residents from residential areas were similar with those of several foreign countries.

Because of its strong potential for health hazards, the concentration levels of airborne lead (Pb) have been circumscribed by environmental laws in many countries. In this study, we made a comparative study on the environmental behavior of Pb for the acquisition of its distribution characteristics using data sets collected from major cities in Korea for a period of 6 years (1998 through 2003). According to this study, Pb concentration decreased slowly in most industrialized cities of Koreathroughout the whole study. period. In contrast, such temporal signals were not evident in data sets collected from residential, commercial, and grassland areas. Although seasonal patterns generally exhibited the occurrences of high Pb concentration during the spring, results appear to reflect the influence of Asian Dust (AD) in the springtime. The results of our study clearly indicate that Pb distribution is strongly influencedby source types in relation to their land use patterns. Comparison of our Pb data sets with that of other countries indicates that Pb concentration levels obtained from relatively cleaner districts of Korea are still significantly higher than other countries. The results of this analysis generally indicate that Pb concentrations in most areas are affected by the type and strength of man-made activities. Considering that most areas are affected by a variety of pollutants, continuous efforts are needed to control Pb concentrations in the atmosphere.

This case study was conducted by verification the site characteristics based on the questionnaire and interview obtained from the all factories located at No. 1 developing area in Kumi industrial complex. The site characteristics were presumed from the process of location behavior and spatial linkage. Kumi industrial complex was developed to improve export industry at national levels by providing chief land price and benefiting various tax. Kumi industrial complex which enticed many factories is playing an important role in export industry in Korea. At beginning, the detention of large enterprises promoted the establishment of related small to medium sized factories into the complex. Two distinctive industries. textile and electronic, were reflected by the purpose to establish the complex and industrial characteristics of Taegu city. respectively. In Kumi industrial complex, positive responses on traffic and raw material supply and negative reactions on the environmental impact on social community as well as high labor charge were investigated. Especially the higher labor cost prevented to hire laborers effectively. In the linkages of spatial and raw material, most factories in the complex depended on the availability of out side the Kumi city. For the textile factories, the supply of raw material and parts were relied on Taegu and/or other cities, whereas in electronic factories purchased them mainly from other cities and partly from abroad. Although questionnaire and interview suggested it, most of the parts were supplied by a parts maturing companies on the complex to a few large enterprises. In the marketing linkage, textile factories revealed higher relation-ship with the foreign countries and sewing factories in Korea. On the other hand, electronic factories have strong relation-ships in the marketing linkage to the parts supplying companies in the complex or large-scale resembling companies in other cities. In the textile companies, the right for decision on purchasing raw materials and parts is belonging to the owner whereas mother enterprise usually have the right for the marketing. In the case of the electronic factories, all the purchasing activities are related to the sub-contracting companies. In the service linkage, the Quality of the service created spatial distinction. There was high linkages on inside of Kumi complex for the low grade services such as repairing and installing machines, whereas strong linkages on outside of the complex for the high grade services such as management, law, taxation, new product development. and manufacturing technology. In the linkages of activity on the R&D (research and development), electronic factories do not have sufficiently qualified institutes in the complex. Strong regional linkages in the field of textile and electronic industries revealed limitations of the local industrial complex. In the sub-contracting linkage, high linkage ship within Kumi boundary reflected the characteristics of industrial site in the complex. There, most decisions by the companies centered by the mother enterprise.

남,북한에 존재하는 다양한 종류의 신재생에너지 분야 중 풍력자원은 지역마다 많은 편차를 가지고 있으나, 2007년에 북한지역의 풍력자원을 분석한 결과 풍부한 자원을 가지고 있는 지역이 많은 것으로 분석되었다. 북한은 과거에도 그렇고 현재에도 전력난으로 많은 어려움을 겪고 있으며, 이를 극복하기 위하여 북한의 국가과학원, 김일성종합대학, 김책공대 등에서 신재생에너지를 활용한 전력난 해소를 위하여 다양한 기술개발을 하고 있다. 따라서, 성공한 신재생에너지 기술을 활용한 태양광 풍력 등을 설치하여 주택이나 공업지역 등에 전력을 공급하고 있다. 그러나 북한의 자본과 기술개발의 한계로 인하여 부품조달 등 공급의 한계성을 가지고 있는 실정에 있다. 최근 남북 학술교류를 통하여 북한의 신재생에너지 개발 현황 및 한계성을 파악할 수 있었으며, 이러한 문제점을 해결하기 위해서는 남한이 가지고 있는 기술력과 북한의 인력을 활용하여 공동개발 및 보급을 촉진할 수 있으리라 사례되며 몇 가지 제안을 하고자 한다.
