  • This study is aimed to quantitatively evaluate the effects of drought on groundwater system in rural areas. For this purpose, the standardized groundwater level index (SGI) was used for 68 groundwater monitoring wells. To determine accumulation period (AP) which represents the month with the highest correlation coefficient between SGI and SPI, correlation analysis between the two for 68 wells were peformed. The results indicated the AP values ranged in 1~3 months for most of the well, but it was 7~10 months in some wells. These results can be interpreted such that the total amount of groundwater will not decrease significantly in long-term drought situations unlikely the reservoirs with the high AP values. The nationwide maximum AP values were 4.1 and 4.0 in Chungbuk-do and Gyeongnam-do, while the minimum AP values were 1.8 and 2.0 in Gangwon-do and Chungnam-do, respectively. The maximum and minimum values of correlation coefficient were 0.623 and 0.459 in Gyeongnam-do and Chungnam-do/Chungbuk-do, respectively. Consequently, it could be concluded that the wells with low AP value tend to respond to short-term drought, but it has little effect on groundwater system when the long drought occurs.

  • This study was performed to find out the clusters with high parasite infection risk to discuss the geographical pattern. Clusters were detected using SatScan software, which is a statistical spatial scan program using Kulldorff's scan statistic. Information on the parasitic infection cases in Korea 2011-2019 were collected from the Korea Centers for Disease Control and Prevention. Clusters of Ascaris lumbricoides infection were detected in Jeollabuk-do, and T. trichiura in Ulsan, Busan, and Gyeongsangnam-do. C. sinensis clusters were detected in Ulsan, Daegu, Busan, Gyeongsangnamdo, and Gyeongsangbuk-do. Clusters of intestinal trematodes were detected in Ulsan, Busan, and Gyeongsangnam-do. P. westermani cluster was found in Jeollabuk-do. E. vermicularis clusters were distributed in Gangwon-do, Jeju-do, Daegu, Daejeon, and Gwangju. This clustering information can be referred for surveillance and control on the parasitic infection outbreak in the infection-prone areas.

  • This study was conducted in an effort to identify the fluctuation of species according to space and time by collecting information on samples of Korean Sphingid moths housed in Korea. The number of Sphingidae moth species housed in Korea was found to be 53. As 48 species and 47 species were found in Gyeongsangnam-do and Gangwon-do, respectively, relatively diverse species were considered to be distributed in these areas. Comparatively, in Jeollabuk-do only 36 species were found, whereas in Chungcheongbuk-do and Jeju Island 39 species were found. The number of individual Sphingid moths surveyed in Korea was 21,414. With regard to the number of individuals per species, Ampelophaga rubiginosa was highest, at 2,483, followed by Theretra japonica (1,716), Callambulyx tatarinovii (1,457), Acosmeryx naga (1,340), Rhagastis mongoliana (1,191), Marumba sperchius (1,083), and Dolbina tancrei (1,072). By region, the largest number of individuals was surveyed in Gyeongsangnam-do (4,595), followed in order by Gangwon-do (3,648 individuals), Gyeonggi-do (3,011), Jeollanam-do (2,454), and Jeju Island (2,382). Over time, the highest numbers-in this case 9,498 individuals in 52 species-were identified after 2000. In the 1990s, there were 6,027 of 49 species identified; in 1980s, 4,332 individuals of 49 species were identified; and, in the 1970s, 937 individuals of 45 species were identified. It was confirmed that more species and individuals were identified as time passed. The appearance of Sphingid moths by month was found to be as relatively diverse, as they appeared from February to November. Overall, southern species, including M. saishiuana, Cephonodes hylas, Acosmeryx castanea, T. nessus, and T. clotho, which mainly inhabit Jeju Island and the southern part of Korea, have increased over time from the past to the present. Species inhabiting the middle or northern parts of the Korean Peninsula or the entire country of Korea, including Sphingulus mus, Ambulyx schauffelbergeri, and Mimas christophi, show decreases over time.

  • 대설로 인한 시설 농가의 피해를 예방하고 경감시키기 위해서는 기존의 적설 깊이와 더불어 적설하중에 대한 예보가 추가로 제공되어야 한다. 본 연구에서는 눈의 밀도 및 적설하중과 관련하여 해외 연구에서 사용하고 있는 이론과 공식들을 검토하고, 이를 국내에서 장기간의 농업기상관측 이력을 가지고 있는 수원에 적용하여 얻는 적설하중 결과를 소개하였다. 지난 30년(1988~2017) 간 국내 94개 기상대와 무인자동기상 관측소에서 측정된 적설(3시간 신적설, 최심신적설, 최심적설) 깊이 자료를 이용하여 우리나라 대설주의보와 대설경보에 해당하는 적설 깊이의 빈도를 살펴보았다. 우리나라 권역별 적설빈도 공간분포를 보면 대설주의보에 해당하는 신적설은 전북지역에서 많이 발생했고, 대설경보에 해당하는 신적설은 경북과 강원지역에서 많이 나타났다. 기록적인 대설은 경북과 강원지역에서 나타났으나, 최근의 겨울철 대설 피해는 경기, 경북, 전남에서 나타났다. 즉 적설 깊이가 깊더라도 적설하중이 무겁지 않다면 큰 피해가 발생하지 않는 것을 확인할 수 있었다. 수원지역의 적설하중을 추정한 결과를 보면 공식들에 따라 다양한 값들과 특징을 보였다. 대부분 적설 깊이가 깊을 때 적설하중이 무겁게 나타났지만 최대적설하중과 최심적설이 반드시 같은 날에 발생하지는 않았다. 이러한 수원지역의 결과는 다른 지역에서의 적설하중을 추정하는데 도움을 줄 수 있고, 온실구조 설계 기준의 표준 확립과 적설하중 예보를 통해 농가의 경제적 손실을 줄이는데 기여할 것이다.

  • This study aims to find the characteristics of damage and states of natural disasters at the Korean Peninsula from 1985 to 2004. Using the data of Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration. we have analyzed the cause, elements, and vulnerable regions for natural disasters. Major causes of natural disaster at Korean Peninsula are four, such as a heavy rain, heavy rain typhoon, typhoon, storm snow, and storm. The frequency of natural disaster is the highest from June to September. The period from December to March also shows high frequency. The total amount of damage is high during the summer season(Jul.-Sept). The period from January to March shows relatively high amount of damage due to storm and storm snow The areas of Gangwon-do, Gyeongsangnam-do and Gyeongsangbuk-do are classified the vulnerable region for the natural disasters. By establishing mitigation plans which fit the type and characteristics of disaster for each region, damage from disaster can be reduced with efficient prevention activities.

  • Hypoptychus dybowskii, the Korean sandlance, is widespread in cold areas of the North Pacific. Although H. dybowskii has been considered to occur on the coast of Hamgyeongnam-do in Korea, the species is also distributed along the coast of Goseong-gun, Gangwon-do, south of Hamgyeongnam-do in the eastern part of the Korean Peninsula on the basis of newly collected specimens. In addition, many Koreans confuse H. dybowskii and Ammodytes japonicus (= A. personatus for Korean specimens) because the Korean common name or dialect of both species is "Yang-mi-ri", yet the two species differ in their external morphology. Hypoptychus dybowskii differs from A. japonicus in the location of the origin of the dorsal fin and the number of dorsal and anal fin rays.

  • A tineid genus, Rhodobates Ragonot, 1895 in Myrmecozelinae is reported for the first time from Korea, with a congener, R. cupulatus Li and Xiao, 2006. The voucher specimens of the species comprise four males and four females collected from Seoul City, Sejong City, Gangwon-do, Chungcheongbuk-do, and Chungcheongnam-do. Among the previously-known species of Tineidae in Korea, Rhodobates cupulatus is similar to Psychoides gosari Kim and Bae in having the uniform coloration over the body and wings, but differs from the latter in the much larger body size. External appearance and genital features of R. cupulatus are redescribed and illustrated. A COI sequence of R. cupulatus is provided for the first time and compared in the world database of DNA barcodes. The Korean records of the species represent the first evidence of its occurrence out of the type locality. Circumstances of its collecting in Korea suggest that it is possibly feeding on dead woods in damp environments.

  • 국내 강원도에서 많이 산출되는 석회암은 다양한 분야에서 활용도가 매우 높다. 이러한 석회암 광상 개발을 위해서는 석회암에 대한 특징 파악이 중요하다. 따라서 이 연구에서는 대표적 탄산염암인 석회암 성분 중 방해석과 백운석의 분광 특성을 측정하여 두 광물을 구분하고자 한다. 연구지역은 강원도 강릉시 옥계면은 옥천변성대 지역으로 석회암, 백운암, 고품위 석회암이 많이 산출되는 지역이다. 분광 특성 측정은 ASD사(Analytical Spectral Device Inc.)의 FieldSpec® 3 스펙트로미터 장비를 사용하였으며 현장 및 실내에서 분광 특성을 측정하였다. 현장에서는 암석 표면을 측정하였으며 실내에서는 암석 표면, 연마면 및 파우더 상태에서 반사도를 측정하였다. 그 결과 2,330 nm를 전후로 방해석과 백운석의 흡수대 위치가 확연히 차이가 나는 것을 확인하였다. 특히 방해석에 비하여 백운석의 흡수 파장대 위치가 2,330 nm 파장 이전에 나타나는 것을 알 수 있었다. 이 연구는 향후 고품위의 방해석 산출에 기초 자료로 활용이 가능할 것이다.
