The water retention capacity of forest leaf litter was estimated through lysimeter measurements under field conditions. Six lysimeters were placed in Pinus koraiensis and Quercus acutissima forests filled with the surrounding to represent effects type on capacity. Two years for rainfall weight have been conducted all at 30 min intervals. Field showed that P. stored more during periods than did Q. litter. As a result, immediately after cessation rainfall, 1.82 mm 3.00 retained per unit mass...

Forest fires can have a direct and immediate impact on soil properties, particularly water repellency. This study investigated the impacts of Gangneung forest fire 2019 properties spatial variability repellency with vegetation burn severity in Korean red pine (Pinus densiflora Siebold Zucc) South Korea. A total 36 samples were collected at depth intervals 0–5 cm, 10–15 20–25 cm from three burned sites, representing surface-fuel consumption (SC), foliage necrosis (FN), crown-fuel (CC),...

This study was carried out to investigate the effects of kimchi powder addition on quality properties semi-dried pork jerky. Jerky unamended (control) or amended with dried a concentration 1% (T1), 2% (T2) 3% (T3). The contents moisture and ash were highest in T3 treatment. protein content control, but there no significant difference fat content. control exhibited pH value, whereas T2 lowest metmyoglobin dry yield water activity treatment highest. There thiobarbituric acid value. Shear force...

The presence of macroroughness elements directly affects the flow velocity in mountain headwater streams. Hydraulic roughness is dominant resistance to caused by objects protruding into water, but it not measurable field. This study quantified reach-average hydraulic based on channel morphology two average velocities reaches were measured using dye-tracing method. magnitude was derived from grain size streambed materials (D50 and D84) cross-sectional/longitudinal bed roughness. observations...

Intestinal mucosal mast cell (MMC) responses were studied in rats experimentally infected with Metagonimus yokogawai (Digenea: Heterophyidae). Twenty Sprague-Dawley fed each 2,500 metacercariae isolated from the sweetfish and sacrificed on week 1, 2, 3 4 post-infection (PI). Recovery of worms was performed small intestine rat. To visualize MMCs, duodenal jejunal (upper, middle lower) tissue sections made stained alcian blue/safranine-0. The average worm recovery rates 16.2% 13.8% 1...

This study performed in order to evaluate the effects of pipe materials on corrosion and bacteria regrowth using a laboratory scale batch test. Two varieties feed water with different microbial conditions were selected: tap water, surface river (Han River water), five materials; carbon steel, copper, galvanized iron, stainless PVC, Carbon steel iron pipes showed higher rates than other materials. In terms attached bacterial growth, PVC concentration compared Pseudomonas vesicularis was...

Abstract For high-dimensional classification, interpolation of training data manifests as the piling phenomenon, in which linear projections vectors from each class collapse to a single value. Recent research has revealed an additional phenomenon known ‘second piling’ for independent test binary providing theoretical understanding asymptotically perfect classification. This paper extends these findings multi-category classification and provides comprehensive characterization double...

본 논문은 총독부가 조선에 도입한 '보속적 임정'에 대한 성격과 한계를 파악하고자 했다. 이를 위해 1926년 조선임정계획에서 표방한 핵심 목표인 목재 자급화 정책과 국유림 수익으로 민유림을 조림한다는 기획의 실상을 분석했다. 연구의 결과 조선총독부가 조선의 자급화를 실시한 이유는 산림자원 현황에 기반한 것이 아니라, 일본 무역 수지 악화에 따른 이입재 방어가 원인이었다. 또한 정책에 따라, 산림수익이 증가했음에도, 사방사업에 사업공채 발행이 계획대로 되지 못하여, 민유림 조림 사업에 투자되었어야 할 이 수익금이 사방사업비로 전용되었음을 밝혔다. 이처럼 총독부의 임정'은 일본의 수급, 안동재 수입 증가, 조선사업공채 발행 등, 제국 단위의 임정과 재정정책에 의해서 일정한 임계점을 가졌다. 그 시기에 임정'을 표방했음에도, 벌채와 조림의 균형은 무너질 수 밖에 없었다.

The purpose of this research is to estimate the economic impact marine tourism and leisure industry on local economy. In order accomplish purpose, we categorize using proportion number workers in 2013 regional I-O table. study calculates production inducement coefficient, employment coefficient impacts, which can provide implications policymakers, related financial institutions public with basic data for developing as strategic job creation Busan.

In this study, a survey of the number excess water quality standards, an average concentration analysis, and trend analysis to calculate grade groundwater contamination using data from monitoring network (GQMN) in Gyeonggi-do were conducted. A pollution map underground was provided, characteristics between items influencing factors identified by statistical analysis. The indication rate-the ratio three determined indicators-from high low Cl- (31.2%) > NO3--N (27.9%) pH (20.8%)...

본 논문에서는 중심신경망을 이용하여 위성영상으로부터 직사각형 형태의 3차원 건물의 지붕모델을 재구성하는 방법을 연구하였다. 제안된 지붕모델 재구성 기법의 핵심은 선소의 군집화에 있다. 이를 위해 한 쌍의 스테레오 영상으로부터 구해진 DEM (Digital Elevation Map) 데이터와 2차원 선소에 의해서 3자원 선소를 발생하였다. 군집화 과정은 이용한 방법에 의해 수행되며, 2단계로 구성된다. 첫 번째 단계에서는 선소 추출과정에서 끊어지거나, 중복된 건물을 이루는 주된 선소로 군집화하고, 두 구성하는 구하기 서로 평행인 선소들의 군으로 군집화를 수행한다. 이 결과를 최종 클러스터링 과정을 통해 지붕모델로 재구성하게 된다. 방법이 대전지역의 고해상도 IKONOS 위성영상에 실험되었다. 재구성된 건물모델이 원래 위치와 형태를 대체로 정확히 반영하여, 논문에서 기법을 적용하여 도시지역의 건물모델을 구축하는데 효과적으로 사용될 수 있음이 입증되었다. This paper...

Fires can burn canopy fuel and replace leafy crowns with charred branches trunks, thereby affecting hydrological flow water chemistry. However, little is known about the effects of fire on throughfall volumes chemical fluxes in temperate forests. Therefore, we aimed to monitor volume chemistry pine trees (Pinus densiflora) damaged by 2022 Gangneung-Donghae Forest Republic Korea. Immediately after forest fire, funnel-type measurements were performed collect beneath five at foliage necrosis...
