The effect of environmental factors on the over-wintering success of the apple snail, Pomacea canaliculata, which is considered as unable to hibernate during winter climate in Korea. This study was examined to determine the location of over-wintering habitats in the agricultural water system related with weed control using the apple snail in rice paddy field in the Yeongnam district from 2003 to 2006. Over-wintering success of the apple snail was observed at Hadong, Hapchen, Sanchung, Kimhae, Milyang, Changwon, Ulsan, Busan, Gyengju, Pohang, Chilgok, Seongju, Gumi, Sangju and Youngju in Yeongnam area. And the over-wintering locations of apple snail going north year by year. Accordingly, the successful over-wintering sites observed were deep wells, water running canals and brooks not dried conditions. A special feature of this sites was that the water of this sites was not frozen during winter season.

To quantitatively predict the impacts of large-scale volcanic eruptions of Mt. Baekdu on air quality and damage around the Korean Peninsula, a three-dimensional chemistry-transport modeling system (Weather Research & Forecasting - Sparse Matrix Operation Kernel Emission - Comunity Multi-scale Air Quality) was adopted. A worst-case meteorology scenario was selected to estimate the direct impact on Korea. This study applied the typical worst-case scenarios that are likely to cause significant damage to Korea among worst-case volcanic eruptions of Mt. Baekdu in the past decade (2005~2014) and assumed a massive VEI 4 volcanic eruption on May 16, 2012, to analyze the concentration of PM_2.5 caused by the volcanic eruption. The effects of air quality in each region-cities, counties, boroughs-were estimated, and vulnerable areas were derived by conducting an exposure assessment reflecting vulnerable groups. Moreover, the effects of cities, counties, and boroughs were analyzed with a high-resolution scale (9 km × 9 km) to derive vulnerable areas within the regions. As a result of analyzing the typical worst-case volcanic eruptions of Mt. Baekdu, a discrepancy was shown in areas between high PM_2.5 concentration, high population density, and where vulnerable groups are concentrated. From the result, PM_2.5 peak concentration was about 24,547 ㎍/㎥, which is estimated to be a more serious situation than the eruption of Mt. St. Helensin 1980, which is known for 540 million tons of volcanic ash. Paju, Gimpo, Goyang, Ganghwa, Sancheong, Hadong showed to have a high PM_2.5 concentration. Paju appeared to be the most vulnerable area from the exposure assessment. While areas estimated with a high concentration of air pollutants are important, it is also necessary to develop plans and measures considering densely populated areas or areas with high concentrations of susceptible population or vulnerable groups. Also, establishing measures for each vulnerable area by selecting high concentration areas within cities, counties, and boroughs rather than establishing uniform measures for all regions is needed. This study will provide the foundation for developing the standards for disaster declaration and preemptive response systems for volcanic eruptions.

This study was carried out to investigate the occurrence and distribution of ALS inhibiting herbicide-resistant weeds and to estimate the appeared areas of resistant weeds in the paddy fields of Gyeongnam province of Korea in 2017 and 2018 using a soil assay method. Compared with the 2012 survey, this study showed that the infested ratio of ALS inhibiting herbicide-resistant weeds increased from 1.0% to 66.8% and the infested area increased from 876 ha to 49,008 ha. The infested area of ALS inhibiting herbicide-resistant weeds was estimated in Ulsan-si (8.4%), Hapcheon-gun (8.3%), Haman-gun (7.9%), Goseong-gun (7.9%), Hadong-gun (7.3%), Jinju-si (7.2%), Changnyeong-gun (7.0%), Gimhae-si (6.4%), Miryang-si (5.5%), Busan-si (4.9%), Uiryeong-gun (4.6%), Namhae-gun (4.3%), Geochang-gun (4.2%), Changwon-si (3.8%), Geoje-si (2.9%), Yangsan-si (1.8%), Sancheong-gun (0.9%) and Tongyeong-si (0.4%), and the herbicide resistant weeds was not occurred in Hamyang-gun. The most dominant ALS inhibiting herbicide-resistant weeds in paddy fields were Monochoria vaginalis, followed by Echinochloa oryzicola, Lindernia dubia, Scirpus juncoides, Ludwigia prostrata, Cyperus difformis, Sagittaria trifolia and Rotala indica. ALS inhibiting herbicide-resistant M. vaginalis, L. dubia, and E. oryzoides occurred throughout Gyeongnam province, and ALS inhibiting herbicide-resistant S. trifolia and R. indica were only found in Gimhae-si. Therefore, these results will be utilized to estimate population dynamics of ALS inhibiting herbicide-resistant weeds and provide proper management practices in the paddy fields of Gyeongnam province.

The usage or agricultural chemicals is on the increasing tendency. Methyl bromide and organophosphate are the most widely used toxic agricultural chemicals in Korea. We try to set up the methods to detect the accumulation of these chemicals in Korean farmers. Blood samples were collected for 121 farmers of slack's season in February 1998. And survey about arable acreage and usage of the gloves and masks was also performed. Serum cholinesterase activities and bromide concentrations were measured with gold chloride method and colorimetric method. The reference ranges of serum cholinesterase activity and bromide concentration were 1.6~15.9 U/mL and below $72.9{\mu}g/mL$. Serum bromide concentrations of farmers and normal controls showed no differences. Serum cholinesterase activities of farmers were significantly higher than those of normal controls. According to the arable acreages and usage of the gloves and masks, serum bromide concentrations and cholinesterase activities showed no differences. In conclusion, serum cholinesterase activities and bromide concentrations showed no differences between farmers of slack's season and normal controls.

Initially from the Taoist scriptures, 'Dongcheon' is a term that can be regarded as a symbolic place in the real world for the enlightened ones who received relief and peace by restoring the human nature taught in the Confucian school. The long for an ideal world apart from the reality embodied as the labeling some places 'Dongcheon,' and the term was used to refer to a scenery where the ideal fairyland is reproduced. Besides, 'Dongcheon' was a term often used by Confucian scholars for various purposes including the attachment to the nearby landscapes, expressing homogeneity and superiority through placeness and the beautification of settlement spaces. This paper is the result of a field study on 'Dongcheon' in the Gyeongsang-Do. The research was conducted from March to August 2018, and we carried out firsthand location surveys on Dongcheons, of which some were lost, others were fairly preserved, and still others could not be located as only their existences were passed down orally. According to the field survey, there were total 111 inscriptions or engravings on the plates in Gyeongsang-Do that include the term 'Dongcheon.' There were 79 'Dongcheon' inscriptions confirmed in the Gyeongsangbuk-Do region: twenty in Yeongju-City, sixteen in Bonghwa-Gun, eleven in Andong-City and seven in Yeongyang-Gun and Ulgin-Gun. Among them, two were in the form of a wooden sign, and six were erected as rock signposts. Fourteen stops reported in the literature were lost or unidentified. Also, among the sixteen signs in Bonghwa-Gun, nine were cursive engravings. Meanwhile, there were 26 Dongcheon inscriptions in the Gyeongsangnam-Do region. Hamyang-Gun and Sancheong-Gun anf Hadong-Gun each housed three inscriptions, and seven places were in the form of rock signposts. 'Hwagaedongcheon' and 'Geumsandongcheon' could not be identified in inscriptions although they appear in Jibong Yuseol and Taengniji with stories of Choi Chiwon. The significance of this study is as a reference for future researches in traditional scenery, epigraphs, or as primary data that helps cultural exploration in the region.
