In this study, we assessed the functional characteristics of Aralia continentalis Kitagawa (AcK) and Aralia continentalis Kitagawa leaf (AcK-leaf), including crude saponin contents, antioxidant activity, nutritive elements, dietary fiber, and chlorophyll contents. The results of our analysis of nutritive elements in AcK, the contents of the general components, inorganic components, and vitamins were all relatively high. The contents of inorganic components were also high in the following order: K>Ca>P>Na>Mg. Among vitamins, $\beta$-carotene and vitamin C contents were all high. The crude saponin content was 63.7 mg/g in the AcK and 63.5 mg/g in the AcK leaf, and the antioxidant activity was determined to be relatively high. With regard to the dietary fiber content, the total dietary fiber content was 2.13% (soluble 0.40, insoluble 1.72) in the AcK and 5.98% (soluble 1.06, insoluble 4.89) in the AcK leaf, and the total chlorophyll content was 92.58 mg in the AcK and 147.25 mg/100 g in the AcK-leaf.

현대를 사는 사람들은 땅이름에 별로 큰 관심을 갖지 않는다. 바로 우리 고향의 이름이고 또 우리 마을의 이름인데도 그러하다. 땅이름은 그냥 편하게 불리면 그만이라는 생각들이다. 그 땅이름이 어떤 뜻을 지녔건 또는 어떤 역사적 사실을 간직했건 그런 것에 별로 아랑곳하지 않는다. 그러나 조금만 관심을 가지고 돌아보면 이 속에 우리말이 그대로 살아 있고 역사가 살아 숨쉬고 있음을 알게 된다. 그리고 우리 조상들의 숨소리까지 배어있음을 느끼게 된다. 그래서 결국은 우리의 뿌리를 돌아보게 하고 생각의 울타리안에 그 ‘옛날’을 잠시나마 잡아다 앉히고 싶은 충동에 빠질 것이다. 이처럼 우리 땅 이름에 얽히고 설킨 뿌리를 찾아 국토의 옛날과 오늘의 근원과 정서를 되살려보는 뜻에서 이번호부터 "우리 땅 이름의 뿌리를 찾아서"를 연재한다.

금강산 개발계획의 결실이 가시화되자 출판계 안팎에서는 북한땅에 대한 책에 새삼 관심이 쏠리고 있다. 그동안 북한땅을 다룬 책들은 정보접근의 한계로 부족한 점이 많았던 게 사실. 북한의 자연이나마 공유하자는 최근의 움직임이 다양한 북한땅 관련 출판물로 이어지길 기대하는 분위기다.

내가 대금을 지불하고 어렵게 장만한 땅. 그러나 등기부등본상에 내가 아닌 엉뚱한 사람이 주인으로 등재돼 있다면 어떤 심정일까? 더구나 그는 이런 점을 악용해 제3자에게 땅을 파는 등 재산권 행사를 강행할 때 어떻게 대응해야 할까? 이렇게 억울한 일을 당했다면 법원에 소유권보존등기의 말소등기 청구를 통해 땅을 되찾을 수 있다. 하지만 문제의 땅이 실제 내 것이라는 것을 입증하기 위해선 매매계약서 등 증거서류를 챙기는 것이 필수적이다.

The aim of this study was to provide basic data that could identify and help prevent a slow-moving landslide using an analysis of the relationship between below-ground characteristics and water from three slow-moving landslide areas in Pohang, Gyeongsangbuk-do, South Korea. Surface surveys, resistivity, seismic exploration, well logging, and boring surveys were conducted in the three areas. The main direction of discontinuous surface was matched with the slope direction of the three landslides. The results indicatedthat slow-moving landslides might occur in the direction of the slope. Underground water was distributed within the crush zones within the three landslide areas and flowed along the tensile cracks. There was a significant difference (p<0.01) between the mean angle of the tensile cracks and that of the underground waterflow (p=0.8019). These results indicated that the progress of a slow-moving landslide can be forecast by monitoring the location and flow of underground water within a known slow-moving landslide area.

With the aim of restoring slow-moving landslide areas, this study collected fundamental data from tree-ring analysis of curved trees in these areas. We collected both upper and lower stem disks to measure the azimuth angles of six trees with growth curvature caused by tension cracks. Additionally, we analyzed various factors in the slow moving landslide area. The geological strata and main constitutive rocks in the study area were anorthosite-formed in the Precambrian period; moreover, there were no intrusive rocks, other geological strata, geological folds, or faults. The talus with weathered rocks was distributed in the upper zone of the slow-moving landslide area. According to annual-ring analysis of curved trees and terrain analysis by satellite imagery, slow-moving landslide occurred from the top to the bottom end of the slope between 1999 and 2011. There was a significant relationship (P < 0.01) between the azimuth angle of cracks caused by the slow-moving landslide and the angle of the curved trees. These results suggest that the occurrence of slow-moving landslides could be confirmed through analysis of annual-rings of curved trees, underground water levels, and terrain (by satellite imagery).

This study was conducted to provide basic data for classifying patterns of land creep in 37 areas in South Korea using geological and soil property analyses. Geological time, as it relates to land creep areas in South Korea, had been most impactful for the Gyeongsang Supergroup and its sedimentary bedrock during the Cretaceous period. In this area, perfect ridge cliffs in land creeping areas included 20 plots (approximately 54.0%), while tension cracking areas with ambiguous ridge cliff characteristics included 17 plots (approximately 46.0%). Hesitant slide slope types included 20 plots (approximately 54.0%) within theslide slope of an incident pattern (slide slope figure) in land creeping areas. Colluvial debris types among land creep patterns were the most frequent and included 25 plots (approximately 68.0%). The direct causes of land creep were cutting of foothills, quarrying, land-clearing in mountains, mining exploration, and the creation of burial grounds, all of which added to geological impacts. Among land creeping areas, 27 plots (approximately 73.0%) were the result of man-made activities, and 10 plots (approximately 27.0%) were derived via natural causes such as earthquakes, heavy rainfall, and caving.

This study was carried out to establish basic data for the development of slow-moving landslide hazard classes. Mountain slopes in slow-moving landslide areas ranged from $11.8^{\circ}$ to $37.0^{\circ}$ with a mean slope of $23.8^{\circ}$. However, the slope inclination of microtopography in slow-moving landslide areas was slightly different, with a mean slope of $23.5^{\circ}$ ($10.7^{\circ}{\sim}41.5^{\circ}$) compared with the mountain slope. There was a significant difference (p < 0.05) between the contour intervals of microtopography and the contour intervals of the slow-moving landslide areas. Among all the slow-moving landslide areas examined, 14 plots (approximately 38.0%) were classified into landslide hazard class I, 6 plots (approximately 16.0%) into landslide hazard class II, 5 plots (approximately 14.0%) into landslide hazard class III and IV, and 16 plots (approximately 43.0%) into landslide hazard class V, whereas 9 plots (approximately 24.0%) fit the no landslide hazard class.

This study characterized areas at risk of land creep by focusing on a site that has undergone this phenomenon in Ulju-gun, South Korea. Land creep in the area of interest was catalyzed by road expansion work conducted in 2022. The site was examined on the basis of its geological features, topography, effective soil depth, soil hardness, electrical resistivity, and subsurface profile. It consists of a slope covered with sparse vegetation and a concave top that retains rainwater during rainfall. Compositionally, land creep affected the shale, sandstone, and conglomerate formations on the site, which had little silt and more sand and clay compared with areas that were unaffected by land creep. An electrical resistivity survey enabled us to detect a groundwater zone at the site, which explains the softness of the soil. Finally, the effective soil depth at the land creep-affected area was 30.4 cm on average, indicating deep colluvial deposits. In contrast, unaffected sites had an effective soil depth of 24.7 cm on average. These results should facilitate the creation of systems for monitoring and preemptively responding to land creep, significantly mitigating the socioeconomic losses associated with this phenomenon.
