  • 본 논문에서는 자동차후면추돌이나 에어백시험 등에서 인체모형의 중요한 평가지수인 목 상해를 평가 할 수 있는 평가시스템에 대하여 연구하였다. 목 상해($N_{ij}$) 기준만족여부를 판단하기 위하여 Diadem 프로그램을 이용하여 더미(Dummy)의 종류별, 시험의 조건별로 자동으로 계산되는 평가시스템을 개발하여 목 상해 기준을 보다 편리하고 정확하게 계산 할 수 있도록 하였다.

  • This research was carried out three times in the Dongdaesan, the Dongpigol camping area and the Sangwonsa from June 1995 to September 1995 to study insect fauna(Hemiptera, Coleoptera and Lepidoptera) in Odaesan National Pard. Eleven jamilies and 15 species of Hemiptera, 20 families and 40 species of Coleoptera and 11 families and 42 species of Lepidoptera was collected and identified. Among these, 12 species of Hemiptera, the 21 species of Coleoptera and 22 species of Lepidoptera were first reported in Odaesan. Including these first found insects, 8 families and 36 species of Hemiptera, 26 families and 97 species of Coleoptera, 30 families and 274 species of Lepidoptera are reported from Odaesan. The species inventories for Hemiptera, Coleoptera and Lepidotera were made from present study and previous works.

  • In case of damaged timber sleepers, maintenance is carried out according to the track inspection standard. However, it is difficult to detect the extent of damage on the bridge, and maintenance is depended on inspector's judgment. In this study, we propose to improve the evaluation criterion of timber sleepers for the ballast-less tracks on serviced urban railway bridge. The timber sleepers on railway bridge was classified according to degree of damage, and damage scores were calculated for each damage grade. Also we have improved the maintenance system of the timber sleepers through the history management system of the individual timber sleepers on railway bridge. As a results, it was judged that systematic management of timber sleepers could be possible during maintenance.

  • Terrestrial insect fauna was surveyed in the Junam wetland area, which consists of the Junam, Dongpan, and Sannam wetlands, by visual counting and pictures. A sweep net collection was conducted from May to October 2010. A neighburing artificial lotus wetland was also surveyed for comparison. A total of 5,730 insects were surveyed, representing 268 species in 85 families and 12 orders. Sixty-three species of coleopterans were surveyed, followed by 60 species of Lepidoptera, and 37 species of Hemiptera. Coleopteran individuals were 25.9% of the total insect numbers surveyed, comprising most abundant group. This was followed by Odonata, Lepidoptera, and Orthoptera at 22.3%, 15.4%, and 12.7%, respectively. In total, 197 species were surveyed in the Dongpan wetland, 175 in the Junam wetland, and 154 species in the Sannam wetlands. However, only 86 species were surveyed in the artificial lotus wetland. Galerucella nipponensis in Coleoptera, Crocothemis servilia mariannae in Odonata, and Polygonia c-aureum in Lepidoptera were the most abundant in all four wetlands. Community analyses showed that the dominance index was highest in the artificial lotus wetland at 0.25 and lowest in Junam wetland at 0.08. Diversity indices were relatively high in all wetlands at 4.48, 4.44, 4.28, and 3.87 in Junam, Dongpan, Sannam, and the artificial lotus wetland, respectively. The insect fauna similarity index was highest in the Junam and Dongpan wetlands at 0.96. The lotus wetland showed the lowest similarity of the three wetlands with values of 0.45-0.53.

  • The study of insect fauna in Taeanhaean National Park in Korea began with the first survey of natural resources in 1996, and then the surveys were conducted seasonally from 2005 to 2014. The surveyed sites were mostly coastal areas, sand dunes, and back grasslands. Insects were collected by sweeping with insect net, suction, pitfall trap, light trap, and Malaise trap. As a result, a total of 1,540 species of 215 families belonging to 17 orders were identified. Lepidoptera was the most populous group at 34.2% and followed by Coleoptera at 28.3%, Hemiptera at 12.7%, Diptera at 8.5%, Hymenoptera at 7.1%, Orthoptera at 4.7%, Odonata at 2.0%, and others. The analysis of change of arenaceous insect fauna before and after the accident by the Hebei Spirit that spilt oil in Taean in December 2007 showed that 45 arenaceous insect species, mostly belonging to Coleoptera, were observed through the whole survey period. The impact of oil spill on the number of arenaceous insect species appearing in the area was minor.

  • 동굴생물은 식물과 동물, 미생물로 크게 구분되지만 태양광선이 완전히 차단된 동굴내 환경에서는 동굴동물들이 주종을 이루고 있다. 동굴내의 동물에 관한 연구는 1966년 고씨동굴, 용담굴을 시발로 고수굴, 천동굴, 노동굴, 백용굴, 대이굴 한선굴등 강원도내에 분포하는 동굴중 약 30%정도는 동물을 포함한 생물상이 조사되었다. 강원도의 동굴동물로서 확인된 것은 9강 309 141종이며 강별로는 충강이 9목 50종 주형강이 4목 49종 갑각강이 6목 18종의 순으로 우세하고 목별로는 거미 목이 15과 39종, 톡토기목이 7과 20종, 딱정벌레 목이 8과 15종으로 우세한 편이다(남, 1987)(중략)

  • This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

  • 나자식물은 구과목(Coniferales), 주목목(Taxales) 그리고 은행목(Ginkgoales)이 있으며 바늘잎을 가져 흔히 침엽수로 알려졌다. 국제자연보호연맹(IUCN)의 침엽수전문가그룹에 따르면 지구상에 살아있는 구과목과 주목목의 침엽수는 8과 68속의 600여종에 이르며 송백류로 부른다. 남한 면적의 67%에 이르는 660만ha에 삼림 중 침엽수림은 273만ha(42.4%), 침엽수와 활엽수 혼합림은 185만ha(28.8%)로 활엽수의 168만 ha(26.0%)에 비해 훨씬 넓지만 침엽수에 대한 관심은 적다.

  • Although typically classified as AIS 1, whiplash injuries continue to represent a substantial social problem with associated costs estimated at over $1 billion annually. The primary objective of this study was to determine the effects of seat positions(seatback angle, headrest height) on risk for whiplash injury in very low speed(${\Delta}V$=4~10km/h) rear-end impact. To accomplish this, rear impact seat carriage tests and simulations were conducted using the BioRID-II dummy seated in a mass production seat, which allowed for the adjustment of seatback angle and headrest height. Neck injury criteria(NIC, Nkm) were then compared for different ${\Delta}V$ and seat positions.
