1989년 8월 강원도 양양군 현북면 광정천과 양양읍 남대천에서 잡은 은어에서 요꼬가와 흡충 피낭유충 감염상을 조사하였다. 광정천산 은어는 조사한 28마리 모두(100%)가 피낭유충 양성이었고 어체 마리당 89∼521개 (평균 224개), 어육 g당 12∼55개 (평균 22개)의 감염량을 나타내었으나, 남대천산 은어(6마리)에서는 피낭유충이 검출되지 않았다. 이상의 결과로 강원도 양양군 현북면 지역이 요꼬가와흡충 유행지의 하나임을 확인하였다.

Distribution of vascular plants in Yangyang-gun were investigated 12 times from Apr. to Sept., 2008. In the result of survey, the flora of this area consist of 412 taxa totally; 89 families, 259 genera, 366 species, 5 subspecies, 37 varieties and 4 forms. There were remarkable plants such as 11 taxa of Korean endemic plants, 58 taxa of specific plants which were designated by the Ministry of Environment, 2 taxa of endangered plants of Ministry of Environment, 7 taxa of rare, endangered plants of Korea Forest Service and 28 taxa of afforestation plants and 296 taxa of useful plants. Furthermore, 36 taxa of naturalized plants (8.74%) were also observed in this area. Vegetation of investigated area was conserved well. However, vegetation has been destroyed rapidly due to construction of commercial complex for human recreation such as condominiums and stores. Therefore, it is need to efficient management of the water quality and vegetation by conservation strategies from huge visitors.

1989년 8∼9월에 강원도 양양군 현북면에서 잡은 집쥐 2마리에서 Echinostoma hortense, E. cinetorchis, E. revolutum, Echinoparyphium recurvatum, Fibricola seoulensis 및 Plagiorchis tsuris 등 모두 6종류의 장흡충을 검출하였다. 이들 중 E. revolutum과 E. recurvatum은 국내산 집쥐에서는 처음 발견되었기에 형태학적 특징의 기술과 더불어 보고하고자 한다. E. revolutum은 충체가 길쭉하며 채장 5.3∼6.0mm, 체폭 1.0∼1.3mm이었다. 두극의 수는 모두 35∼37개이었으며 end group spine이 좌우에 각각 5개씩 있었다. 길다란 자궁은 굽어져 있었고 충란이 가득 들어 있었다. E. recurvatum도 충체가 긴쭉하였으며 체장 3.5∼4.7mm이었고 체폭 0.50∼0.65mm이었다. 두극의 수는 모두 45개이었으며, 복측 양단에 위치한 end group spine이 각각 4개씩 있었다. 짧은 자궁 내에는 소수(10개 미만)의 충란이 들어 있었다. 이상의 결과로 국내의 집쥐가 자연계에서 E. revolutum과 E. recurvatum의 종숙주 역할을 하고 있음을 확인하였다.

The natural habitats and distribution of five rare plants were recently discovered in Korea. Salomonia oblongifolia DC., which grows in mountain wetlands, was found in Gijang-gun, Busan, Gokseong-gun, Jeollanam-do, and Shinan-gun, Jeollanam-do. Glaux maritima var. obtusifolia Fernald, which grows along the coast, was found in Yangyang-gun, Gangwon-do, Pohang-si, Gyeongsangbuk-do and Buk-gu, Ulsan. Tillaea aquatica L. and Limosella aquatica L., which was previously not known to be present in Korea, were discovered in Gijang-gun, Busan for the first time. Apocynum lancifolium Russanov, which has a narrow distribution range in Korea, was also found in Samcheok-si, Gangwon-do, Ansan-si, Gyeonggi-do, Siheung-si, Gyeonggi-do, Jung-gu, Incheon, Yeongdeok-gun, Gyeongsangbuk-do and Shinan-gun, Jeollanam-do.

When we looked at the seasonal food dregs of the eastern side of gangwondo, gangneung city's summer and winter food dregs showed 25.9 and 25.8% respectively due to the presence of beach areas and ski resorts. Sokcho city showed 28.12% in summer and yangyang gun's summer food dregs showed 40.2%. Yangyang gun's august food dregs showed 2.7 times larger than annual average amount. Outlook density showed regional characteristics. Data showed that food dregs' amount rate has been reduced gradually from 2005 because of the prohibition of direct filling up. As a result of compositions analysis, the eastern side of gangwondo's water fraction of living dregs were lower than that of chuncheon city where is located at the gangwondo's inland area. chuncheon city's data showed residential areas 53.5%, community areas 56.8% and commercial areas 55.6%. These discrepancies caused by the characteristics of dregs discharge type and climate. The caloric value of dregs has been increased incrementally after the ban of food dregs' direct filling up. Therefore, heating value of the dregs exceeds the existing furnace design spec and it can cause high caloric value problems, so we need additional research to solve these problems.

Planting pine trees on the coastal dunes has been carried out along the East coast as well as West coast of South Korea. Although the artificial forestation has been regarded as a good policy that help to protect the coastal area from natural disasters, but its real effect to the landscapes is still unknown. In this study, we have installed a monitoring site with an automated weather station to study requirements for dune formation and its environmental changes in Osan beach, Yangyang-Gun, Gangwon Province. We analyzed the meteorological data collected from 2010 to 2019 and vegetational changes in the study area. As a result, the wind speed is decreased by around 30% and the pine-covered area is increased by around 300m² after planting Japanese Black Pine in 2015. At present, it seems that the eolian transport of sand particle is minimal, because the dominant winds are the westerly winds which is not landward but seaward, and because the surface roughness length is about 0.5m which is similar to that in the deciduous forest.

Objectives: In an effort to examine the distribution of THMs (Trihalomethane) generated from chlorine disinfection by the drinking water treatment plants located on the east coast region of Gangwon-do, this study surveyed the distribution and concentrations of each component of THMs twice per month for 5 years from 2008 to 2012. Fluctuation pattern in the seasonal generation amount was identified. In addition, the correlation between the concentration of organic substances in water and THMs was assessed, along with stability of purified water quality supplied by the water treatment plants on the east coast by analyzing the composition ratio of each component that constitutes THMs and the detection frequency. Method: The research was done on purified water supplied by 29 water treatment plants in 7 cities and counties (Goseong-gun, Sokcho-si, Yangyang-gun, Gangneung-si, Donghae-si, Samcheok-si, Taebaek-si) located in Gangwon-do on the east coast. Water samples were collected twice a month from 2008 to 2012 and were investigate for chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform, based on analysis through Purge-Trap (Tekmar 3000) devices using FID-attached GC (HP 6890, Hewlett Packard). Result: THMs concentration detected at Gangneung-si was 0.0086mg/L, Goseong-gun 0.0019mg/L, Donghae-si 0.0099 mg/L, Samcheok-si 0.0016 mg/L, Sokcho-si 0.0057 mg/L, Yangyang-gun 0.0027 mg/L and Taebaek-si 0.0038 mg/L. As the THMs composition rate, chloroform constitutes 51.4% followed bybromodichloromethane 22.3%, bromoform 15.2% and dibromochloromethane 11.1% respectively. Conclusion: Throughout the entire THMs survey areas and period, the maximum concentration was 0.072mg/L, which did not exceed the water quality standards (0.1 mg/L), and the overall average concentration was very low at 0.0044 mg/L.

This study is to evaluate the per capita accessibility to child care facilities using road map in rural village unit considering the supply and demand of child care facilities in municipal (Si-Gun) units. Using these estimated accessibility, the most accessible regions to child care facilities was identifies using Moran's index. Assuming establish a new child care facility in the most accessible region, the sensitivity of child care environment was analyzed. The number of regions are 71 si-gun-gu where supply of child care facilities is insufficient. The average accessibility per capita is 1.09 km to child care facilities and the average accessibility in Myeon unit is approximately 2.2 times higher than accessibility in Eup unit (Eup unit 0.54 km, Myeon unit 1.21 km). Approach tendency from village to child care facilities has positive relationship as 0.451 global Moran's index. The high-high (H-H) accessibility regions are wide as Gangwon-do, Gyeongsangbuk-do, Gyeongsangnam-do, Jeollanam-do and Chungcheongbuk-do. Assumed to be established the new child care facilities in Yangyang-gun (Ganwon-do), accessibility changes of child care environment are up to 2.7 times greater and the recipient population is 77% of Yangyang-gun.

이 연구는 2016년 9월에 강원도 양양군 남애리, 경상북도 포항시 구룡포읍 석병2리에 설치한 인공어초를 대상으로 해조류 군집 변화를 관찰하기 위하여 연구를 수행하였다. 현장조사는 2017년 2월, 5월, 8월, 11월에 계절별 1회씩 SCUBA Diving으로 수행하였으며, 정량조사와 정성조사를 병행하였다. 본 연구에서 녹조류 11종, 갈조류 15종, 홍조류 68종을 포함하여 총 94종이 채집되었으며, 양양에서 66종(녹조류 8종, 갈조류 9종, 홍조류 49종), 포항에서 65종(녹조류 7종, 갈조류 9종, 홍조류 49종)이 채집 및 동정되었다. 중요도를 기반으로 판단한 우점종의 경우, 양양은 다시마(Saccharina japonica)가 우점종, 구멍갈파래(Ulva australis)가 준우점종이었으며 포항은 불레기말(Colpomenia sinuosa), 우뭇가사리(Gelidium elegans) 순으로 우점하였다. 두 해역 모두 어초 설치 초기에 각각 파래류, 불레기말이 착생한 후, 다시마, 감태, 우뭇가사리 등 다년생 해조가 생육하며 우점하여 기존의 천이 패턴과 유사하였다. 해조상 변화를 통해 군집관계를 명확히 하기 위해서는 추후 지속적인 모니터링을 통해 장기적인 변화를 관찰하여 해조군락이 안정되기까지의 천이 과정에 관한 모니터링이 필요한 것으로 판단된다.
