본 연구에서는 서울의 세 지점에서 이동 및 고정오염원이 대기질과 도시 공원 토양의 특성에 미치는 영향을 파악하고자 하였다. 조사 대상지로는 도시에서 질소 침적의 주요 발생원인 이동 및 고정오염원의 여부에 따라 서울시 마포구의 하늘공원 (Site_M), 서울시 강남구의 일원에코파크 (Site_G), 서울시 서초구의 양재시민의 숲 (Site_Y)을 선정하였고, 각 사이트별 교통량과 대기질 농도, 토양 분석 결과를 비교하였다. 교통량은 Site_G와 Y에 이어 Site_M에서 가장 많았다; Site_M과 G는 Site_Y보다 자원회수시설과 더 가까웠다. 따라서, 본 연구에서는 PM과 NO₂ 농도가 Site_Y, G에서보다 Site_M에서 많을 것이며, 사이트마다 다른 대기 침적량에 의해 토양 질소 함량도 다를 것으로 예상했다. 예상과 동일하게 PM2.5와 NO₂ 농도는 Site_M과 G에서 높았지만 PM10 농도는 Site_Y에서 약간 높았다. 식물이 주로 흡수하는 무기질소의 형태인 NO₃^-의 함량은 세 사이트에서 유의한 차이가 보이지 않았고, NH₄⁺의 함량은 Site_Y에서 다른 두 지역에 비해 더 높았는데, 이는 대기 침적에 의한 결과라기 보다는 공원 관리 차원에서의 질소 비료 투입에 따른 영향인 것으로 생각된다. Site_Y에서 다른 사이트보다 낮은 pH를 보인 것 또한 과다한 비료 시용으로 인해 산성화가 일어난 것으로 생각된다. 그러나 토양 내 NH₄⁺ 함량이 상대적으로 적은 Site_M과 G를 포함한 모든 조사 대상지에서 식생이 건강하게 보이는 것으로 보아, 공원 관리에 있어서 과도한 비료 투입을 재고할 필요가 있음을 시사한다. 비록 이동 및 고정오염원으로 인해 대기의 PM, NO₂ 등의 농도가 달랐지만 그 영향이 토양의 질소 영양 상태에 직접적 영향을 미치지 않는 수준이었다.

본 연구는 도시 숲 산림치유프로그램 교육 및 활동이 정서적 쉼(치유회복환경지각, 주의회복, 여가생활만족)에 어떠한 영향을 미치는지를 확인하려는 목적이 있다. 이를 위해 38명을 대상으로 실험군(산림치유프로그램교육 및 실습), 대조군(프로그램 미참여)으로 나누어 연구를 진행하였다. 연구결과, 실험군의 경우는 프로그램 사후에 정서적 쉼 요소인 치유회복환경지각, 주의회복, 여가활동만족 모두에서 통계적으로 유의하게 향상되었고, 대조군의 경우는 사후에 정서적 쉼에 대한 변화가 없었다. 또한 참여자 그룹 간 정서적 쉼 차이에 대해서는 사전과 사후에 모두 그룹 간 차이가 있었는데, 사전 차이에 비해 사후 정서적 쉼 차이가 훨씬 더 크게 나타났다. 결론적으로 산림치유에 대한 교육을 정기적으로 받고 실제 산림치유활동을 한 사람들은 그렇지 않은 사람들에 비해 정서적 쉼을 더 높게 경험하는 것을 알 수 있다. 이는 단순히 산림활동에 대한 긍정적 인식을 가지고 임의로 산책 활동하는 것보다 적절한 프로그램을 통해 지속적인 동기부여 및 정기적인 실천이 치유회복환경에 대한 인식을 높이고 주의회복을 증진시키며, 여가생활에 긍정적 효과를 줄 수 있음을 시사한다.

In this study, the fly ash was employed as a possible alternative to the bentonite for its high sorption capacity against cationic heavy metal. To consider the constituents of barrier possibly used, the specimens were mixed with different material contents (fly ash : weathered soil : bentonite), then sorption test was performed. Also the specimens were molded on the wet side of optimum moisture contents like mixing ratio of sorption test and their hydraulic conductivities were measured in flexible-wall permeameters. And to confirm the effect of dissolved cations, the hydraulic conductivity tests were repeated by converting the permeant liquids from water to $Cd^{2+}$ solution. Finally, the Cd-concentration at the effluent was analyzed for 500hrs to compare the effectiveness of each specimen in contaminant retardation. Test results showed that the more the ratio of fly ash increase, the more Kd value increase, and the hydraulic conductivity of weathered soil/bentonite (95:5) mixture was the lowest $(2.9*10^{-8}cm/sec)$, and specimens made of fly ash and fly ash/weathered soil mixtures showed similar hydraulic conductivity. Although the permeant liquid was changed from water to $Cd^{2+}$ solution, the hydraulic conductivity of all specimens except for weathered soil maintained similarly like before. Consequently, the initial breakthrough point of Cd in weathered soil specimen was observed at about 5hrs after the test started while that of fly ash specimens was not observed during the whole test period of 500hrs. The results implied that fly ash had a sufficient retardation capacity against contaminant transport possibly by its high sorption capacity although it showed little effect on the reduction of hydraulic conductivity. Based on the test results, it could be concluded that the fly ash can be possibly used as a suitable barrier material in containment system to attenuate the contaminant transport for its high retardation capacity and for the low cost.

The total pollution load management system of watershed has been implemented upon Special Law pertaining to the Han River Watershed Water Quality Improvement and Residents Support, Special Law pertaining to the Nakdong River Watershed Water Management and Residents Support, Special Law pertaining to the Youngsan River Watershed Water Management and Residents Support, and Special Law pertaining to the Seomjin River Watershed Water Management and Residents Support in Korea since 2002. But many other similar systems with total pollution load management system of watershed are being operated separately or independently, even though its purpose is nearly same with those of the total maximum pollutants load management in Law on Water Quality Environmental Protection, environmental impact assessment(EIA) in Law of Impact Assessment on Environment, Transportation and Disaster and Pre-environmental assessment of Environmental Policy Act. Therefore the contents of total pollution load management system of watershed and many other related systems could be overlapped and at some times have inconsistency among them. This study suggests first the integrated operation of total pollution load management system of watershed, EIA, pre-environmental assessment, urban planning, and sewage planning and secondly EIA system development by integration of EIA and pre-environmental assessment and strategic environmental assessment(SEA).

Many studies have suggested the positive effects of grazing by large herbivorous mammals on seed dispersal, but little is known about how herbivores could affect the fate of ingested seeds. This study examined the effects of seed ingestion by sika deer (Cervus nippon) on seed fate in a temperate grassland established in an urban park long resided by high densities of sika deer. I compared species composition and seasonal traits of seed abundance and maturity in the grassland community with those in deer fecal pellets. In total, 27 herbaceous species were observed, including the predominant Zoysia japonica. Seed phenology and production differed among the three dominant species (Z. japonica, Digitaria violascens, and Hydrocotyle maritima). Pellets contained at least 26 species of herbaceous seeds, and their abundance differed among species. Of the 26 species, 15 were observed in the vegetation at the study site. The peak of seed abundance in pellets for the dominant species appeared 1 month after the peak of inflorescence production (but most of the inflorescences were immature and susceptible to digestion) and consequently corresponded to the peak of mature inflorescence. Because sika deer are likely to ingest seeds at any maturity stage in the grassland and immature seeds are less hardened, ingested immature seeds can suffer great losses. The results suggested that the survival of germable seeds with great losses of immature seeds may be a factor determining which plant species can be successfully dispersed by herbivores.
