우리나라 4대 강 중에서 낙동강 권역은 관광자원 측면에서 볼 때 다양한 관광자원을 보유하고 있음에도 불구하고, 기존 연구는 수자원의 산업적 이용과 상수원 확보 차원에서 수질보전과 유지에 대한 환경학적 연구가 주종을 이루었다. 따라서 본 연구는 문화관광학적 관점에서 낙동강 권역을 조명하고 문화재의 분포특성을 분석하였으며, 다음과 같은 연구결과를 도출하였다. 첫째, 지방분권시대의 도래를 앞두고 낙동강 권역의 협치(governance)에 의거 연구대상 범위를 낙동강유역환경청과 대구지방환경청의 관할구역에 따라 연구범위를 설정하였다. 둘째, 본 연구분석 대상으로 문화관광자원 중 국가지정문화재 시도지저문화재 문화재자료 등 문화재 등을 대상으로 하였다. 셋째, 문화관광자원의 지리적 분포는 다음과 같은 특성을 나타내었다. 관할구역에 따른 문화관광자원의 분포는 대구지방환경청이 낙동강유역환경청보다 양적 우세성을 보였다.

The Chemical Substances Control Act has been legislated to counter the risks posed by chemical substances to public health and the environment, but a number of small- and large-scaled incidents related to hazardous chemicals continue to occur every year. The Korean Ministry of Environment takes legal responsibility for prevention, preparedness, and response to nationwide chemical accidents under the Chemical Substances Control Act. The determination of chemical accidents that occur during hazardous chemical handling processes is based on the Article 2 (Definitions) of the law and the administrative criteria for judgement of chemical accidents. However, there are certain ambiguities in the scientific basis for determining chemical accidents under the current regulations. Whether or not a chemical accident has a direct influence on penalties and administrative measures for a workplace where an accident occurred, it is necessary to find reasonable criteria for determining chemical accident based on legal and scientific evidence.

2021년도부터 제3차 비점오염원관리종합대책이 시행되고, 정부 부처 물환경관리 대책도 유역관리중심 강우유출수관리 중심을 전환되고 있다. 이러한 비점오염관리에 대한 정책 변화 발 맞추어 원주지방환경청에서는 지역거점형 「비점오염관리 연구·지원센터」를 설립하고, 강원지역 한강 상류 수계에 분포하고 있는 고랭지밭에서 배출되는 흙탕물 발생 저감을 위한 다양한 발생원 관리 비점오염 저감사업을 추진하고 있다. 그 외에도 강원도 지자체 및 이해관계기관에서는 흙탕물 저감 교육 및 거버넌스 활성화 프로그램 개발 및 운영에 힘쓰고 있다. 이러한 강원지역 비점오염저감을 위한 다양한 노력을 통해 향후 유역단위 흙탕물 저감 방안 마련과 상하류간 이해 증진, 민원 해결, 그리고 비용·경제적 실효성 있는 문제 해결을 기대해 본다.

This case report aims to introduce the safety campaign activities for preventing chemical accidents that were cooperatively conducted by an environmental office and chemical-handling workplaces located in the Ulsan area. A chemical safety campaign was initiated to examine and manage chemical-handling facilities at high risk for chemical accidents, specifically valves, flanges, and switches (VFS) from October 2020 to December 2022. The VFS safety check campaign was conducted to raise workers' safety consciousness based on a campaign of advertisements in the workplace from October 2020 to December 2021. In addition, a VFS plus [+] campaign was initiated to encourage actual management activities for chemical-handling facilities at high risk of chemical accidents in 2022. A total of 49 corporations participated in the VFS plus [+] campaign. In contrast to the VFS safety check campaign, which simply focused on publicity and resulted in changes in worker awareness, practicable safety management activities focusing on the handling facilities were carried out. Although notable short-term impacts have yet to be discerned from the campaigns, it is expected that they will eventually serve as a starting point for developing a proper safety culture and environment.

In this study, we evaluated the fluidity of the Al-Zn based alloys which exhibit excellent mechanical properties. We conducted computer simulations of fluid flow using the results of DSC, DTA analysis and Java-based Materials Properties software (J. Mat. Pro). Such computer simulations were then compared with the results obtained from experimental observations. The computer simulation results and the experimental results were very similar in fluidity length. It was found that the fluidity length of Al-Zn alloys is improved by increasing the Zn content while decreasing the solidus temperature of an alloy. In addition, we elucidate the effect of Zn addition on variations in different mechanical properties and the microstructure characteristics of (Al-xZn3Cu0.4Si0.3Fe) x=20, 30, 40, and 45 wt% alloys fabricated by gravity casting.

Al-Zn based alloys are the most common types of wrought Al alloys. Although Al-Zn alloys have high strength, they cannot be applied to a conventional casting process. In this study, Al-Zn-based alloys applicable to a die casting process were developed successfully. The developed Al-45 wt% Zn-based alloys showed a fine equiaxed grain structure and high strength. A fine equiaxed grain having an average size of $25{\mu}m$ was obtained by the die casting process. The UTS and elongation of the new alloy are 475 MPa and ~3.5%, respectively. In addition, we elucidate the effect of a Zn addition on variations in different mechanical properties and the microstructure characteristics of (Al96.3-xZnxCu3Si0.4Fe0.3) x=20, 30, 40, and 45 wt% alloys fabricated by a die casting process.
