On 6 August 2018, heavy rainfall of daily precipitation of more than 200 mm occurred in the Yeong-dong coastal area, and especially, 1-hour precipitation of 93 mm (0251~0351 LST (local standard time) 6 August) at Gangneung station, ranked second in the history of meteorological survey of the station. In this study, this heavy rainfall case over the Gangneung area would be studied to investigate the process in which the heavy rainfall occurred. A developed ridge moved toward the Yeong-dong coastal area from the Maritime Province in Russia. The approaching of the ridge led to the northeasterly cold wind over the coastal region, causing the collision between the incoming northeasterly cold wind, and the humid and warm (convectively unstable) air located over the Yeong-dong area. This collision led to a strong convergence (maximum -206 × 10^-5 s^-1) at 925 hPa level over the vicinity of Gangneung at 0300 LST 6 August, resulting updraft of up to about 4.4 m s^-1 at 700 hPa level over the area. This strong updraft forced to lift rapidly the convectively unstable, warm and humid air layer, located over the vicinity of Gangneung, leading to the heavy rainfall (1-hour precipitation of 93 mm) over the area.

Simulation results of WRF for the case of typhoon 'Rusa' were analyzed, comparing with observed data especially forjavascript:confirm_mark('abe', '1'); the Gangneung area around to examine its ability in numerical simulation. From the hourly precipitation time series, two peaks were found at Gangneung and Daegwallyeong, while only one peak was found from those of inland regions else. Especially, for the Yeongdong region, the first peak was directly related to spiral bands generated in front of the typhoon. Convective cells that were developed within the spiral bands moved to the eastern coastal area from the sea so that local heavy rainfall occurred in the Yeongdong region. The second peak was mainly related to the accompanying rain band of typhoon itself, topographic effect and the convergence near Gangneung area. Precipitation in Gangneung was simulated as much as about 30% of observed one. The main reason of this result came from a poor representation of wind directions in Gangneung area of WRF model. Observed wind direction was northwesterly but simulated one was nearly easterly in the area. This might shift a local heavy rainfall area downstream to the mountain area rather than the coastal area.

본고에서는 여러 문헌에 흩어진 강릉지역의 팔경을 수집하고, 팔경과 역사문화와의 관계 팔경의 지역적 분포 경관구성 요소 및 내재적 의미를 다각도로 분석 및 해석하였다. 강릉지역의 팔경은 고려에서 근현대까지 오랜 시간 동안 축적 확장되어 왔으며, 단순히 자연경관의 아름다움뿐 아니라 이 지역을 배경으로 한 역사적인 사실과 그 정서를 반영하고 있다. 또한, 강릉지역 팔경의 형식과 분포를 종합하여 볼 때, 가장 많은 형식을 차지하는 것은 소상유사형(瀟湘類似型)이다. 그 중 반복적으로 나타나는 '저녁밥 짓는 연기'나 '고기 잡기' 등은 당시 강릉지역민들의 생활상을 보여주고 있으며, 이는 마을단위로 이루어진 팔경이라는 사실을 말한다. 강릉지역의 팔경은 넓게는 시(市) 전체, 좁게는 누정(亭)까지 다양한 범위에 분포되어 있다. 대부분의 팔경은 현재 강릉시의 동쪽, 그리고 강동면과 구정면이 접하는 지역에 몰려있다. 강릉 지역의 팔경이 대부분 이곳에 분포되어 있는 상황으로 볼 때, 이 지역이 강릉경관의 핵심을 차지하고 있음을 말해준다. 강릉지역 팔경은 자연요소 60%, 인문요소 36%, 기타 4%로 나타났으며 자연요소에서는 대상 그 자체의 아름다움을, 인문요소와 기타에서는 대상 속에 담긴 전설이나 역사를 담고 있다. 팔경이 표현하는 경관들은 별개의 대상이 아니다. 남대천과 죽도봉, 군선강과 풍호 등 하나의 풍경이 되었다. 또한 신라의 화랑의 이야기가 얽힌 풍호, 군선강 등은 강릉지역의 대표적인 역사경관이 되었으며, 강릉지역의 팔경은 견조도, 한송정, 한송사 등 현재는 존재하지 않는 강릉의 유적 및 전통경관을 유추해 볼 수 있는 중요한 기초자료가 될 것으로 판단된다. 결론적으로 강릉지역의 팔경은 미적대상인 동시에 역사 문화적 장소이고 더 나아가 심상적(心象的) 공간으로 남아 있음을 알 수 있다.

Purpose: This study was performed to investigate the bone thickness of the infrazygomatic crest area by computed tomography (CT) for placement of a miniplate as skeletal anchorage for maxillary protraction in skeletal Class III children. Materials and Methods: CT images of skeletal Class III children (7 boys, 9 girls, mean age: 11.4 years) were taken parallel to the Frankfurt horizontal plane. The bone thickness of the infrazygomatic crest area was measured at 35 locations on the right and left sides, perpendicular to the bone surface. Results: The bone was thickest (5.0 mm) in the upper zygomatic bone and thinnest (1.1 mm) in the anterior wall of the maxillary sinus. Generally, there was a tendency for the bone to be thicker at the superior and lateral area of the zygomatic process of the maxilla. There was no clinically significant difference in bone thickness between the right and left sides; however, it was thicker in male than in female subjects. Conclusion: In the infrazygomatic crest area, the superior and lateral area of the zygomatic process of the maxilla had the most appropriate thickness for placement of a miniplate in growing skeletal Class III children with a retruded maxilla.

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

본 고는 강릉지역에서 발굴조사된 고고자료를 검토하여 문헌기록과 비교하면서 신라가 강릉지역으로 진출하여 재지 세력을 지배해 나가는 과정에 대해 가설을 세워 본 것이다. 강릉지역의 고고학적 양상은 신라가 처음 이 지역을 복속하고 재지세력들에 침투하는 과정을 잘 보여주는데, 필자는 이 지역의 5~6세기 고고학적 특이양상에 대해 적극적인 해석을 시도하였다. 강릉지역은 신라 진출 이전 예국이라는 읍락국가가 존재하고 있었다. 신라는 4세기 4/4분기에 처음으로 강릉지역으로 진출하였으며, 기존의 예국을 복속한 후 지역 실정에 맞게 재지세력을 통치해 나갔다. 이에 대해 고고자료와 문헌기록을 비교검토해 본 결과, 신라가 강릉지역을 복속한 후 취한 지배정책은 간접지배와 직접지배의 2단계로 나누어 볼 수 있었다. 간접지배는 다시 초입기(I 단계)와 정착기(II 단계)로 구분하였는데, I 단계는 신라가 처음 강릉지역으로 진출한 시기로 신라는 재지세력의 자치를 그대로 허용하며 간접지배를 실시하였으며, 그 시기는 4세기 4/4분기부터 5세기 2/4분기로 보았다. 그리고 II단계는 신라가 강릉지역의 재지세력들에게 위세품을 하사하여 적극적인 정책을 펼치면서 동시에 신라 중앙에 의해 강릉지역 중심세력인 초당동과 병산동 세력에게 위세품을 분여하여 서로 견제를 하게 만들어 재지세력간 힘의 균형을 통제하였다. 그 시기는 5세기 3/4분기에서 5세기 4/4분기로 추정하였다. 그러나 신라는 강릉지역을 북진의 전초 기지로 인식하고 나서는 직접지배체제로 전환하기 시작한다. 즉, 신라 중앙에서 파견한 지방관을 상주시켜 지방제도를 확립하고 재지세력에 대한 재편과정을 거쳐 중심세력을 초당동 병산동 세력에서 신라와 친연성이 가장 강한 영진리 방내리 세력으로 교체하고 강릉지역을 완전 장악하기에 이른다. 그 시기를 6세기 1/4분기부터로 보았다.

This research aimed to grasp the recognition of the amenity of the university students residing in Gyo-dong residential area in Gangneung city, the local residents residing in Daehag-ro which is near Jungang-ro in downtown and the public servants related to city development in Gangneung city office and thereby propose a plan to improve the amenity of Gangneung city. Based on the result of the research, the university student group around Gyo-dong residential area mostly recognized the amenity and the local residents around Daehag-ro showed insufficient recognition of the amenity and some of related public servants were found to be ignorant of the term amenity. Also, the priorities of amenity indexes identified from these 3 groups commonly showed aliveness requiring green lands and watercourses on top but 2nd priority of each group tended to be different from each other. Through the research result as above, we would like to propose the plan to improve as follows. First, the recognition of the concept of amenity is necessary. Second, green lands and watercourses that were selected by all of the 3 groups as ranking no. 1 should be secured. Third, the value of amenity resources should be evaluated. Gangneung city is a city where mountains and the sea are harmonized together granting abundant god blessed natural resources. But if Gangneung city would imprudently reclaims the excellent god blessed natural environment under the good title of city and housing lands development, its ranking in city competitiveness evaluations will be expected to continue descending. Therefore, as proposed in this research, the thing that has to be implemented with first priority for amenity Gangneung city is the execution of amenity policy to secure the identity of Gangneung city and the aspect of regulations or systems should also be pursued together with the policy.

This study aimed to determine the fluoride intakes in 120 preschool children aged 3 to 6 residing in Jumunjin (community water fluoridation area) and Gangneung (non-fluoridation area). The parents were asked to collect 24-hour urine samples and to duplicate the samples of all the diets that their children ingested in the day of urine collection. The acid-diffusible fluoride in the food and non-carbonate beverages were isolated by the acid-diffusion technique and then measured with a fluoride electrode. The fluoride in carbonate beverages, drinking waters and urine samples were measured directly with a fluoride electrode. The geometric mean (geometric standard deviation) of daily fluoride intakes from all kinds of diet was 5.99 (2.27) $\mu$g/kg/day in the children in Gangneung and that of the children in Jumunjin was 18.36 (2.69). The amount of fluoride intake by food and drinking water in fluoridation area were significantly larger than that in non-fluoridation area but the statistical difference of fluoride intake by beverages between two areas was not observed. The GMs (GSDs) of daily fluoride excretion by urine of children in non-fluoridation area and in fluoridation area were 8.39 (1.73) and 18.62 (1.77) $\mu$g/kg/day, respectively. The correlation between fluoride intake from diet excluding beverage and urinary excretion was statistically significant. It is concluded that the amount of fluoride intake of children living in fluoridation area did not exceed the upper intake level to avoid the risk of dental fluorosis (2.2 mg/day in 4- to 8-year-olds) and urinary excretion of fluoride was good indicator of fluoride intake from diets.

Because of localized extreme rainfall followed by Typhoon Ewiniar in 2006, a lot of landslides and debris flows were occurred in Jinbu area of Gangwon Province. Field investigation performed in this area found that it can be divided into three categories i.e. large debris flow, small debris flow, and debris flow around forest road. We performed field investigation especially for the sites where debris flow occurred around forest road. And the characteristics of the debris flow around forest road were analyzed and compared with the other site of debris flow.
