  • In total, 654,362 adult mosquitoes were captured using black light traps in Gangwon-do Province of the Republic of Korea from 2012 to 2017. The collected mosquitoes were identified to the species level, placed in pools of up to 50 mosquitoes each, by species and date of collection, and screened for flaviviruses using a reverse transcription-polymerase chain reaction assay. A total of 276,224 adult mosquitoes were grouped in 7,721 pools for virus testing, and 68 flavivirus positive pools (0.9%) were detected. Flavivirus-positive products were confirmed by DNA sequencing. Japanese encephalitis viruses were detected in single pools collected from Chuncheon (2012, 2017: Culex pipiens, 2,728 and 1,111 mosquitoes, respectively), Hoengseong (2013: Culex orientalis, 19), and Gangneung (2017: C. pipiens, 724). All the Japanese encephalitis viruses detected were revealed as genotype V. Chaoyang viruses were detected in 63 pools of 5,055 Aedes vexans nipponii and a single pool of 585 C. pipiens collected in Gangwon-do Province from 2012 to 2017. Chuncheon was the region with the highest minimum infection rates (MIR, 0.32) and maximum likehood estimate (MLE, 0.33; confidence interval (CI) 95%, 0.23-0.46) of A. vexans nipponii for Chaoyang virus, followed by Hoengseong (MIR 0.30, MLE 0.30, CI 0.16-0.52) and Gangneung (MIR 0.21, MLE 0.21, CI 0.13-0.31). Monthly MIR and MLE values of A. vexans nipponii for Chaoyang virus were the highest in October (MIR 0.38, MLE 0.38, CI 0.07-1.25).

  • 최근 지구온난화에 따른 기후변화로 인해 집중호우와 태풍의 영향으로 토석류를 동반한 산사태가 빈번하게 발생하고 있다. 산지에서 짧은 시간동안 강우가 집중되어 발생하는 토석류는 고수위의 홍수파를 형성하며 유목 및 흙, 자갈 등이 함께 유동하여 주변도로와 하류지역의 민가나 하천구조물에 큰 피해를 발생시킨다. 특히 강원도 지방도로의 경우 대부분이 산지와 급경사지로 이루어져 있어 집중호우시 산사태나 토석류에 매우 취약한 실정이다. 이러한 피해를 사전에 예방하기 위해 국내에서는 부처별로 다양한 풍수해 관련 재해지도를 작성하여 제공하고 있지만 표준모델이 없고, 서로 다른 형태의 지도를 관리하고 있어 재난 발생 시 도로관리에는 효율적인 활용이 어려운 실정이다. 따라서 본 연구에서는 재난 시 효율적인 지방도로 관리를 목적으로 다양한 재해지도의 중첩을 실시하였다. 또한 도로에서 빈번하게 발생하는 재해를 분석한 결과 산사태와 토석류가 높은 비중을 차지하였으며, 해당 재해지도를 중첩하여 지방도로 중심의 재해지도를 작성하였다.

  • The purposes of the paper are to estimate welfare change from water quality degradation by using contingent valuation method in Namdae stream of Gangrung and identify what factors of Namdae stream are important to Gangrun citizens. The study results show their total WTP per year and per household, \117,040 to improve Namdae stream quality from grade 3 to grade 1, including monetary WTP \87,502 plus opportunity cost of volunteering time for protection campaign, \29,538. The amount of total welfare change from water quality degradation based on the total WTP estimated above is calculated to be \27 billion of which the amount, as a sort of damage cost from water quality degraded, is so huge. All projects and policies related to natural environments, therefore, should consider both indirect and direct effects from them because natural environments have the irreversibility once degraded or deteriorated and would ultimately be influential on humans, both current and future generations, with tremendous amounts of time and costs beyond our imagination.

  • The germination responses of Fraxinus rhynchophylla seeds collected from four provenances to constant temperature were investigated over the range $5{\sim}35^{\circ}C$. Difference among seeds in percentage and rate of germination and cardinal temperatures was observed. The seeds from Inje had high germination percentage at low temperature ($5{\sim}15^{\circ}C$) whereas those from Gangneung had high germination percentage at high temperature ($30{\sim}35^{\circ}C$). Three cardinal temperatures viz., the base ($T_b$), the maximum ($T_m$) and the optimum ($T_o$) for germination percentage and germination rate varied among four provenances. $T_b$, $T_m$ and $T_o$ for F. rhynchophylla seed germination as estimated by the quadratic models were the lowest in Inje while those were the highest in Gangneung. The cardinal temperatures ($T_b$, $T_m$ and $T_o$) were estimated by linear sub- and supra-optimal models for germination rate as a function of temperature response. $T_b$ was the lowest in Hoengseong while that was the highest in Gangneung. $T_m$ and $T_o$ were the lowest in Inje while those were also the highest in Gangneung. That is, the seeds from the provenance where the annual mean temperature was high had the higher cardinal temperatures ($T_b$, $T_m$ and $T_o$) as compared to seeds from the provenance where the annual mean temperature was low.

  • This paper investigates Buddhist sculptures of the Gulsan-sa School of Seon Buddhism, which was established by the priest Beomil(梵日) at Myeongju(溟州), present-day Gangneung(江陵) area, and prospered until the late Goryeo period. There are very few surviving Buddhist images at Gulsan2 temple-site showing the Buddhist art when Beomil or his disciples, Gaecheong(開淸) and Haengjeok(行寂), were active, except a set of huge stone pillars for temple-banners and a stone monk stupa. It is therefore necessary to focus on pieces of artworks in Gangneung and nearby areas to explore the characteristics of Buddhist art of Gulsan-sa from the late Silla to early Goryeo period. For example, the stone relief seated Buddha image, one of Four Buddhas of Four Directions, and a stone relief of standing Guardian King both from the stone pagoda at Mujin temple-site(無盡寺址) can be compared with stupa reliefs at the capital Gyeongju area in their high quality of carving. The stone octagonal base showing seven lions on each of seven sides at Boheon-sa(普賢寺) demonstrates that it was made as a part of an octagonal lotus pedestal for a Vairocana Buddha now lost. Since Boheon-sa was erected by Gaechung, a disciple of Beomil as a branch of Gulsan-sa, it is fair to assume that the Vairocana image at Boheon-sa might have been closely related to the Buddhist images at Gulsan-sa in its style and iconography. The stone seated Bodhisattva from Hansong temple-site(寒松寺址) displays a benign face, exquisite necklace, and exotic iconography in its hand gesture and high cylindrical crown. The stone seated Buddha at Cheonghak-sa(靑鶴寺), brought from a temple-site where fragments of roof-tiles with the inscription of Heukam-sa(黑岩寺) were discovered, displays the late Silla and early Goryeo period. Heukam-sa seems to have been related to Gulsan-sa or have been one of the branches of Gulsan-sa. Extant fragments of artworks at Myeongju implicate the high quality of Buddhist art of Gulsan-sa in its iconography and style as well as unique features of Gulsan-sa Seon School.

  • Congenital tooth agenesis is the most common developmental dental anomaly, of which oligodontia is defined as the absence of six or more permanent teeth, except the third molars. Tooth agenesis causes malocclusion, alveolar atrophy, aesthetic and psychosocial problems. This clinical report describes a multidisciplinary treatment for a patient diagnosed as oligodontia, who exhibited absence of 14 permanent teeth, atrophy of maxillary alveolar bone, and mandibular protrusion. Restoration space was secured and tooth axis was improved by the extraction of deciduous teeth and orthodontic treatment. However, edge-to-edge bite of posterior teeth and arch dimension discrepancy due to atrophic maxilla was remained. To restore the aesthetics and functionality, implant retained prosthesis was planned. Considering minimal bone grafts, location and number of dental implants and prostheses design were determined. Through the gradual adjustment of provisional restoration, the appropriate centric and eccentric occlusion was reflected into a definitive prosthesis. Currently, stable functional results were attained, however, regular follow up and maintenance care over lifetimes should be performed.

  • To use the external connection implant (EXT) appropriately, the inter-implant distance should be carefully considered during placement, and the bones raised above the implants should be trimmed during the second surgery. The hex abutment is more useful than the non-hex abutment. EXT is particularly useful when the inter-arch space is limited. The tissue level (TL, internal butt connection) implant has a biomechanical advantage of coronal wall thickness and a biological advantage of an inherent transmucosal smooth surface. During TL implant restoration, an abutment can be selected using the abutment and fixture margins with considerations for the inter-arch space. Since no single type of implant can satisfy all the cases, it is necessary to select the appropriate type, considering the occlusal force and the bone condition.
