  • Methylmercury is a hazardous substance that is of interest with regard to environmental health, as inorganic mercury circulating in the general environment is dissolved into freshwater and seawater, condensed through the food chain, ingested by humans, and consequently affects human health. Recently, there has been much interest and discussion regarding the toxicity of methylmercury, the correlation with fish and shellfish intake, and methods of long-term management of the human health effects of methylmercury. What effects chronic exposure to a low concentration of methylmercury has on human health remains controversial. Although the possibility of methylmercury poisoning the heart and blood vessel system, the reproductive system, and the immune system is continuously raised and discussed, and the carcinogenicity of methylmercury is also under discussion, a clear conclusion regarding the human health effects according to exposure level has not yet been drawn. The Joint FAO/WHO Expert Committee on Food Additives proposed to prepare additional fish and shellfish intake recommendations for consumers based on the quantified evaluation of the hazardousness of methylmercury contained in fish and shellfish, methylmercury management in the Korea has not yet caught up with this international trend. Currently, the methylmercury exposure level of Koreans is known to be very high. The starting point of methylmercury exposure management is inorganic mercury in the general environment, but food intake through methylation is the main exposure source. Along with efforts to reduce mercury in the general environment, food intake management should be undertaken to reduce the human exposure to methylmercury in Korea.

  • Water quality criteria for human health protection are derived based on the human health risk assessment. Water quality criteria in Korean freshwater bodies have been derived according to the equations developed by the US Environmental Protection Agency. The equations include the fish intake parameter, which is very important factor that significantly influences on the criteria derivation. So far, several fish intake values were used in human health risk assessment for water quality standards and effluent standards. However, these values are not consistent and they refer to various sources. Therefore, there is a need to suggest the most appropriate value of fish intake parameter to derive freshwater quality criteria in Korea. In this study, national and international fish intake values were widely collected and evaluated to select the adequate value of fish intake parameter that can be applied in Korea. The USEPA presented fish intake parameter as the 17.5 g/day for general adults and sport fishers and 142.4 g/day for subsistence fishers. In Korean reports, wide range values of 2 to 67.7 g/day were suggested as fish intake value. These values included finfish and shellfish intakes in common but had various habits. This study found that the 52.4 g/day suggested in Korean Exposure Factors Handbook published by the Ministry of Environment in 2007 seemed to be the suitable fish intake parameter to derive the freshwater quality criteria in Korea. The value is based on water corrected intakes of finfish and shellfish present in freshwater and coastal areas. We expect that this report can be useful to select suitable fish intake value in human health risk assessment for establishing freshwater quality standard in Korea.

  • 본 논문에서는 메타버스 공간을 문화적 인간의 미래를 위한 생활환경으로 바라보고 있다. 메타버스라는 공간은 비록 디지털 '가상' 공간으로 인식되지만 현실과의 연장선상에서 이해되어야한다. 신체를 떠나 살 수 없는 인간이 디지털 공간에서 탈육체화의 욕망을 꿈꾸지만, 신체를 가진 인간은 물리적 환경과 완전히 떨어질 수 없다. 이는 메타버스 공간에서 인간의 활동이 현실과 단절된 것이 아니라, 현실의 사회문화적 맥락 속에서 인간의 실존적 삶의 방향을 찾아야함을 의미한다. 메타버스라는 삶의 양식이 현재 보다 더욱 일상화된다면, 인간은 이 메타버스 세계를 현실 세계의 맥락에서 인간의 생활환경으로 접근할 수 있어야한다. 따라서 본고에서는 창작과 유희, 공감의 세계를 창조하는 메타버스를 호모 쿨투랄리스의 생활환경으로 고찰해보고, 그 세계 내 존재 인간의 욕망과 욕망 실현의 공간 플랫폼으로서 메타버스를 살펴보고자 한다.

First, as a result of examining whether skin care salon decision factors during the pandemic have a positive (+) effect on customer satisfaction, hygienic environment satisfaction and service environment satisfaction, which are sub-factors of customer satisfaction, had a significant effect on professionalism, kind service, and distance, which are sub-factors of decision factors, and are independent variables. Second, as a result of examining whether skin care salon decision factors during the pandemic have a positive (+) effect on revisit intention, decision factors, which are independent variables, including professionalism, kind service, price, and distance showed significant effects on human revisit intention, As for physical revisiting intention, only kind service, distance, and professionalism showed significant effects, while price did not have a significant effect. Third, as a result of examining whether customer satisfaction during the pandemic has a positive (+) effect on revisiting intention, the service environment satisfaction and hygienic environment satisfaction, which were sub-factors of independent variables, showed significant results for human and physical revisit intentions. In this study, service environment and hygienic environment satisfaction were important variables for skin care salon decision factors. Professionalism and kind service were important for human revisit intention. Therefore, overall service environment, hygiene, and safety should be prioritized to increase revisit intention and efforts must be made to retain and improve customer satisfaction

  • Ondal Cave is important and significant in terms of cultural value and tourism. In addition, there are abundant historical and cultural resources nearby. If the geographical strength is taken advantage of, the cave would evolve into a great tourist destination and natural education spot. This paper has investigated humanistic environment of Ondal Cave in considerations for the surrounding tourism resources. There are abundant tourism resources around Ondal Cave. However, they are rarely connected with each other. In fact, they are very partially interrelated around Guinsa(temple) only. Furthermore, the number of tourists has gradually decreased. Therefore, it‘s required to further develop tourism programs and surrounding tourism resources.
