강원도 영월 남부 지역의 청림 일대와 충북 가창산 일대에는 중기 석탄기의 갑산층이 북북서 방향으로 길게 분포한다. 이 연구는 갑산층 내의 석회암의 구성 입자와 조직 및 지화학적 특징, 그리고 석회암의 부존 상태를 규제하는 지질구조를 파악하기 위해 수행되었다. 갑산층의 석회암은 대체로 담회색 내지 담갈색을 띠며, 세립질의 치밀한 조직을 갖는다. 석회암의 구성 입자는 해백합, 유공충, 방추충, 개형충, 복족류 등의 파편으로 이루어졌다. 부분적으로 재결정 작용을 받아 세립의 결정질 방해석으로 이루어지기도 한다. 갑산층 석회암의 CaO, MgO, Al2O3, Fe2O3 및 SiO2의 함량을 분석한 결과 CaO 함량의 범위는 49.78 - 60.63%이며, MgO는0.74에서 4.63% 까지 변화한다. Al2O3와 Fe2O3는 각각 0.02∼0.55%, 0.02∼0.84% 까지 변화한다. 이들은 CaO의 함량이 비슷한 경우 이들의 값도 매우 비슷한 양상을 보여 준다. SiO2는 대부분이 1.55∼4.80% 범위 내에서 변화하나 일부 시료에서 6% 이상의 높은 값을 나타낸다. CaO의 함량을 기준으로 할 때 석회암은 크게 49.78∼56.26%(A군)와 59.36∼60.38%(B군)의 범위 내에 분포하는 2개의 군으로 구분된다. A군의 석회암은 CaO의 함량 변화에 따라 Al2O3, Fe2O3 및 SiO2는 매우 불규칙하게 변화하며, MgO는 대체로 거의 비슷한 값을 갖는다. B군의 석회암 경우 MgO, Al2O3, Fe2O3 및 SiO2는 매우 비슷한 값을 나타내는 특징을 보여 준다. 연구 지역의 갑산층 석회석 자원의 부존 상태를 규제하는 지질구조 요소들은 적어도 다섯 번의 변형작용에 의해 형성되었다. 첫 번째 변형작용은 등사습곡구조를 형성시켰으며, 연구 지역 전역에 걸쳐 발달된 층리면과 평행한 엽리는 축면엽리로서 축을 갖는 노두규모의 습곡구조와 그와 관련된 축면엽리, 파랑습곡구조, 파랑엽리, 교차선구조 등의 지질구조 요소를 형성하였다. 세 번째 변형작용 동안에는 압축응력축의 방향이 대체로 동서 방향으로 바뀌었으며, 노두규모의 습곡구조, 파랑습곡구조, 파랑엽리, 교차선구조 등의 지질구조 요소를 형성하였다. 네 번째 변형작용은 세 번째 변형작용과 동일한 응력환경하에서 거의 연속해서 일어난 것으로 여겨지며, 지질도 규모의 향사구조 및 배사구조를 형성하였다. 다섯 번째 변형작용은 네 단계의 변형작용 중에 형성된 지질구조 요소들을 절단하는 취성 단층운동으로 특징된다. 이 중에서 갑산층 석회암의 분포는 첫 번째 변형작용 중에 형성된 등사습곡과 네 번째 변형작용 중에 형성된 지질도 규모의 향사 및 배사구조에 의해 지배되고 있다.

One genus and two species of fusulinids are collected and described from the upper part of the limestone of the Gabsan Formation, Jecheon area, Chungbuk.

The Diameter at Breast Height (DBH) provides information about the volume growth of a tree. In this study, we estimated the relative growth rates of Castanea crenata and Pinus rigida as 4.07% and 3.73%, respectively. Although the difference was low, we demonstrated that the growth rate of C. crenata is slightly faster than that of P. rigida. After calculating the relative growth rate for each section, we found that the relative growth of C. crenata decreased with time. However, the relative growth rate of P. rigida showed an overall increase. The gap widths of both species showed an increasing trend. However, the gradient of the two species was different. The gradient of C. crenata was approximately 12.0, but that of P. rigida was approximately 4.7. This means that the volume growth of C. crenata was faster than that of P. rigida during 4 years. However, this was relatively a short period for measuring the volume growth pattern, and we believe that additional useful information can be obtained by conducting long-term ecological monitoring. Results of canonical correspondence analysis showed that among the climate variables, temperature was significantly related to the gap widths for both species.

Green Infrastructure (GI) approach provides significant benefits to cities and communities. GI applications would provide multi-benefits such as the reduction in building energy demand, stormwater management, urban heat island reduction, habitat creation, etc. GI is nowadays considered as a multi-benefit best management practice (BMP) at diverse levels of government. The purpose of this study is to find out the positive effects of GI application, and Geographic Information System (GIS) is used for the accurate and efficient analysis. Two polygon data, ‘GreenRoof’ and ‘ParkingPlace’ are produced with a satellite imagery extracted from Google Earth Pro. These data are used to calculate total available spaces for green roof and permeable pavement in the campus of Chungbuk National University. After GI application in the campus, 13.2% of landcover is converted to green spaces and this change results in expanding the green network of Cheongju city. The result of this study shows that green roof application can absorb 4576.95 kg/yr of Carbon Dioxide and possibly reduce maximum 1,497,600L urban runoff. This study proves how GI is valuable for the city environment with quantitative analyses.

This study aims to assess Green-Tourism accessibility of Rural Experience Village and then prepare improvement methods. To do this study, we surveyed 25 operators of Rural Experience Village in Chungbuk. We used 21 issues in all for analysis and the following shows a summary of major results. Rural Experience Village has a generally hard time conducting facility maintenance. Countermeasures for maintenance are required to run smoothly. Since Rural Experience Village has difficulty attracting visitors to the village, countermeasures are needed to attract visitors through business promotion. The results of assessing Green- Tourism accessibility showed us that some villages are a lot more accessible than others. Therefore, it is necessary that there should be improvements of Green -Tourism accessibility by attracting visitors and increasing operating days so that Green-tourism accessibility can be enhanced. In spite of its high level of accessibility since Rural Experience Village belonging to Goesan has low profitability, it is especially imperative that we establish more positive project promotion to cover it.

The Earth’s outer radiation belt often suffers from drastic changes in the electron fluxes. Since the electrons can be a potential threat to satellites, efforts have long been made to model and predict electron flux variations. In this paper, we describe a prediction model for the outer belt electrons that we have recently developed at Chungbuk National University. The model is based on a one-dimensional radial diffusion equation with observationally determined specifications of a few major ingredients in the following way. First, the boundary condition of the outer edge of the outer belt is specified by empirical functions that we determine using the THEMIS satellite observations of energetic electrons near the boundary. Second, the plasmapause locations are specified by empirical functions that we determine using the electron density data of THEMIS. Third, the model incorporates the local acceleration effect by chorus waves into the one-dimensional radial diffusion equation. We determine this chorus acceleration effect by first obtaining an empirical formula of chorus intensity as a function of drift shell parameter L*, incorporating it as a source term in the one-dimensional diffusion equation, and lastly calibrating the term to best agree with observations of a certain interval. We present a comparison of the model run results with and without the chorus acceleration effect, demonstrating that the chorus effect has been incorporated into the model to a reasonable degree.

The greenhouse gas emission according to the energy consumption is the cause of global warming. With various climates, it is occurs the direct problems to ecosystem. The various studies are being to reduce the carbon dioxide, which accounts for more than 80% of the total greenhouse gas emissions. In this study, estimate the carbon usage using potential biomass extracted from forest type map according to land-use by satellite image, and estimate the amount of carbon dioxide, according to the energy consumption of urban area. The CO2 adsorption is extracted by the amount of forest based on the direct absorption of tree, the other used investigated value. The CO2 emission in Jecheon was 3,985,900 TCO2 by energy consumption. At the land cover classification, the forest is analyzed as 624,085ha and the farmland is 148,700ha. The carbon dioxide absorption was estimated at 1,834,850 Tons from analyzed forest. In case of farmland, it was also estimated at 706,658 Tons.

Astronomical Observations at Chungbuk National University Observatory (CBNUO) with an 1 m telescope have begun since April 2008, and Near-Earth Space Survey observations also have been started since November 2010, with a 0.6 m wide field telescope developed by Korea Astronomy and Space Science Institute. To improve observational efficiency, we developed a weather monitoring system enabling automatic monitoring for the weather conditions and checking the status of the observational circumstances, such as dome status. We hope this weather monitoring system can be helpful to more than 100 Korean domestic observatories, including public outreach facilities. In this paper, we present the statistic analysis of the weather conditions collected at CBNUO for 3 years (2009- 2011) and comparisons were made for clear nights between using only humidity data and both humidity and cloud data.
