지구온난화와 에너지 위기를 극복하기 위해서 정부와 민간 기업에서 과거 수년 동안 신재생에너지 개발 과 사업화에 많은 노력을 하고 있다. 이에 생활쓰레기와 산업폐기물(폐자원)을 활용한 재생연료의 생산과 이를 활용한 에너지화가 신재생에너지 분야에서 매우 높은 관심 속에서 현장적용을 위한 연구뿐만 아니라 사업화가 일부 추진되고 있다. 그러나 재생연료의 품질의 유지와 연소 특성의 일관성을 유지하기 어려워 실제 재생연료의 활용시 품질의 안정성 확보가 어려웠다. 이러한 원인으로 단일물질인 폐목재와 폐플라스틱을 이용한 재생연료 생산과 활용에 집중되어 있다.
Globalization of Halal Food: A Study on Its Diffusion ‘into’ and Export ‘from’ South Korea
박현서,이영민 한국도시지리학회 2017 한국도시지리학회지 Vol.20 No.3
The article explores the change of Muslim food culture, which is spreading in South Korea, to the export products for the globalization of Korean food, explaining the development of halal food market in South Korea. Recently the Muslims’ halal market is spotlighted by the non-Islamic market as the increase of global Muslim proportion due to the high fertility rate and the potential economic growth in Islamic countries. Focusing on the fact that Muslim culture has already spread in South Korean society since the 1990s, halal food productions spread from Islamic to non-Islamic regions are exported back to the Islamic market through its transformation of identity in this country. While the halal food market located in the ethnic enclave of Muslim migrant workers in the 1990s, it has been able to respond flexibly to growing demand as its distribution network diversifies since the 2000s. As the increase of overseas demand for Korean food by Korean wave, major domestic food companies are making efforts to advance into the global halal market by adopting halal certification system. The government is taking the proactive support through halal food industry development and export activation measures. Halal foods play a multiplicative role in linking the Islamic and non-Islamic regions in that the government promotes Korean food exports and its brand values using the halal certification system.

Relationships between pine-mushroom(Tricholoma matsutake) yield and important climatic factors for the yield(such as monthly precipitation, relative humidity, temperature, and radiation percentage) were examined to find out limiting factors for pine-mushroom production and to develop a method for overcoming the factors by analyzing the yield and climate data for 17 years collected from 18 main regions of pine-mushroom production. Although there were variations among the production regions, climatic condition of September was the most significant factor for pine-mushroom yield in general, and the degrees of importance of each climatic factors were different among the production regions. Mean minimum temperature of September was positively correlated with pine-mushroom yield(r²◎0.41) at the 1% level, of which were 9 regions such as Youngduck, U1jin, Samchuck, Bongwha arid so on. In these regions, vegetation control was expected to be effective for pine-mushroom production by allowing much sunlight penetration to the pine stand, which may increase soil temperature and keeping the temperature around the fungal colony in soil. Precipitation during September was positively correlated with pine-mushroom yield(r²◎0.41) at Namwon, Moonkyung and Sangju. Thus, irrigation around fungal colony in dry soil during September would be effective for enhancing mushroom yield at the regions. Pine-mushroom yield of 1994 was quite low, similar to that of 1993, due to serious drought. In this period, we could manifest the possibility of enhancing pine-mushroom yield by irrigation for overcoming drought at Moonkyung and Keochang regions.
