Young-Chul Kim,Hyun-Hee Chae,Sang-Heock Oh,Seung-Ho Choi2,Moon-Pyo Hong3,Gi-Heum Nam,Jae-Yoon Choi,Hyun-Sook Choi,Kyu-Song Lee 한국환경생태학회 2015 한국환경생태학회지 Vol.29 No.2

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

1970년부터 2002년까지 전국을 조사한 자료 중 외래도입어중인 M. salmoides가 포함된 군집을 대상으로 공존성 및 종간상관성에 대하여 논의하였다. 총 7,192개의 조사지역에서 M. salmoides가 포함된 군집은 46군집, 공존하는 어종은 72종으로 나타났다. 공존성이 높은 종은 Z. platypus, O, bidens, H. eigenmanin, S. japonicus coreanus의 순이었다. 종집단간 공존도는 M. salmoides - Z. platypus 집단, M. salmoides - C. auratus 집단, M. salmoides 집단을 포함하고 있는 군집내에서 7종이 그룹화되었다. M. salmoides가 포함된 군집내에서 O. bidens와 Z. platypuswlqeks 등 7개 종집단은 종간 상관성이 매우 높았으며(p<0.01), L. macrochirus와 C. cuvieri 집단 등 11개 종집단은 종상관성이 다소 높은 것으로 나타났다(p<0.05). 한국의 하천이 점차 호수성하천으로 변화된다고 볼 때, M. salmoides 집단의 조절대책이 필요하다. On the fish community including Micropterus salmoides population, introduced species in Korea, interspecific association through coexistence by presence-absence among species populations were discussed from the year of 1970 to 2002. In the total of 7,192 sampling stations in Korea, the community including Micropterus salmoides population were confirmed at 46 sampling sites, and coexistent fishes were 72 species. Fish species having high coexistence rate were Zacco platypus, Obsarlichthys bidens, Hemiculter eigenmanni and Squalidus japonicus coreanus populations in the order of their number. A association indices values between population were in the order of Micropterus salmoides-Zacco platypus, Micropterus salmoides-Carassius auratus, and Micropterus salmoides-Hemiculter eigenmanni population. Judging from the dendrogram according to association indices between species population, 7 species populations were clustered in the community including M. salmoides population. Being based on association values among species population in the community including M. salmoides population, 11 species population pairs including Lepomis macrochirus -Carassus cubieri etc. showed somewhat high significance (p < 0.05), and 7 species population pair including Zacco platypus-Obsarlichthys bidens etc. represented higher association among species population (p < 0.01). With the increasing of lake- river in Korea, it keenly need to take a regulation program of the Micropterus salmoides population.

본 연구에서는 부력저항용 영구앵커의 거동을 시공단계별로 구분하여 분석한다. 즉, 앵커의 두부에 하중계를 설치하여 앵커축력을 계측하였으며, 이 계측결과를 토대로, 앵커축력의 손실, 건물자중의 증가 및 외적조건 변화에 따른 앵커의 거동을 분석하였다. 영구앵커는 초기인장력에 비하여 Jacking Free시 인장력이 약 7% 정도 감소하며, 최종인장력은 약 15%정도 감소한다. 한편, 앵커의 초기인장력은 외력이 작용하지 않아도 PC 강선의 relaxation, 주입재 및 지반의 creep 등의 내적요인에 의하여 비선형적으로 감소되어 1차 수렴치에 도달하게 된다. 1차 흙되메우기 작업 기간동안 앵커축력은 흙되메우기에 따른 횡방향 토압이 증가 및 상부구조물의 자중증가로 인하여 감소된다. 그러나, 흙되메우기 작업이 중단된 기간동안 되메우기한 흙의 이완현상으로 횡방향 토압이 감소되며 이로 인하여 앵커축력이 증가하게 된다. 그리고, 되메우기한 흙속으로 지하수가 유입되어 부력이 증가하게 되므로 앵커축력은 증가하게 된다. 이때 앵커축력은 1차 수렴치까지 회복하게 된다. The behavior of permanent anchors for buoyant resistance is investigated at each construction stage. The prestressed anchor forces were measured by load cells which were attached to anchor head. On the basis of instrumentation, the loss of anchor force and the behavior of anchor by increment of structure weight and change of external condition were investigated. Prestressed anchor force at jacking free is decreased by about 7% than initial prestressed anchor force and decreased by about 15% finally. Although external forces does not act on the substructure, initial anchor force is decreased nonlinearly due to relaxation of PC strand and creep of grouting materials and soils. Also, anchor force was converged at the first convergent value. When first backfill was performed, anchor force was decreased due to increment of lateral earth pressure and superstructure weight. But, anchor force grew gradually during the period of breaking backfill by lowering of lateral earth pressure due to relaxation of soils. When groundwater inflowed into backfill soils, anchor force is slowly increased by uplift force below mat foundation. At that time, anchor force is recovered by the first convergent value.

암반지반에서 절토나 지하굴착을 실시할 때 암발파로 인해 진동과 소음이 발생하게 된다. 지반진동은 인접구조물에 손상을 주거나 인근주민에게 불쾌감을 주기 때문에 지반진동의 발생기구나 인접구조물에 영향을 미치는 매카니즘을 정확히 예측하는 것은 매우 중요하다. 따라서 본 연구의 목적은 지반진동에 대한 규준을 마련하는데 있다. 지반진동은 최대입자속도, 발파에너지, 진동원으로 부터의 거리에 영향을 받는 것으로 나타났다. 또한, 본 연구에서 산정된 진동식의 최대입자속도는 기존의 제안식보다 약간 작게 나타나고 있으나 진동원으로부터 50~100m 이내의 거리에서는 매우 유사하게 나타나고 있다. Vibration and noises are occured dut to rock blasting work for cutting and underground excavation performed in rock ground. It is very important to control the vibration produced according to rock blasting. Therefore, the main objective of this paper is to estabilish criteria of vibration to control blasting. Vibration is influnced by peck particle velocity, blasting energy, distance from vibration source and strength of rock. The peck particle velocities estimated by the vibration equations presented in this paper are lower than those estimated by existing empirical equations but both show very similar within distance from 50m to 100m.
