  • A total of 827 malaria cases were reported in the Gangwon-do in the year 2000. There were 18.2 cases per 100,000 inhabitants. There were 283 cases among civilians and 544 cases among the military. 90.6% of cases were reported in Cheorwon-(531), Hwacheon- (152), and Goseong- (66) gun (county), which bordered the demilitarized zone (DMZ). A distinct feature pertaining to the malaria cases in Gangwon-do is that the number of cases has increased about two times over the last year. The mean time from the beginning of symptoms to malaria diagnosis was five days. Control systems for malaria by public health organizations and military organizations are well maintained , but were not able to reduce the malaria prevalence rate. The cause for the increase in pattern of the malaria cases in Gangwon-do may be caused by the spreading of prevalent areas of malaria to the east. Continuous endeavor such as early detection of cases, early treatment, education on clinical symptoms and prevention of mosquito bites with repellent and mosquito nets will help to reduce the infection rate of malaria in Gangwon-do.

  • The Seated iron Vairocana Buddha statue of Dopiansa Temple, Cheolwon was designated National treasure No. 63, it is very important to rearch about Korean Buddha statue because it has an inscription on the back indicates that it was made in 865 A.D., the fifth year of the reign of King Gyeongmun(861-875) of Unified Silla(668-935), through the devoted faith of some 1,500 Buddhist followers of the Cheorwon-gun area. In this conservation treatment, for the Seated iron Vairocana Buddha statue of Dopiansa Temple, Cheolwon plating layer and cashew paint layer of the iron pedestal were removed and for the paint the Body of the Buddha, fake metal layer and plaster layer were removed, stabilizing treatment and coating treatment were done, and removal and restoration of earlobe which had been damaged and later was restored with plaster in the regilding in 1988, and the white hair on forehead was replaced with material of rock crystal, and conch-shaped hair damaged was restored on 35 spots.

  • Sclerotinia white rot disease was observed on 5 and 6-year-old ginseng (Panax ginseng) roots in Hongchun, Cheorwon, and Yanggu, Gangwon Province, Korea from 2006 to 2010. Symptoms included a brownish watery soft rot of the roots, and black sclerotia were often found on the rotten roots. The causal agent of the disease was identified as Sclerotinia nivalis based on cultural characteristics and sequence analyses of the internal transcribed spacer region of rDNA and ${\beta}$-tubulin gene with 100% sequence similarity. Pathogenicity tests were performed on 2-year-old ginseng roots with mycelium plugs without wounds. A watery soft rot of the roots and black sclerotia were observed 10 days after inoculation. These symptoms were identical to those observed on naturally infected roots. The same fungus was re-isolated from the lesions induced by artificial inoculation. This is the first report of sclerotinia white rot caused by S. nivalis on P. ginseng in Korea.

  • This study was conducted to investigate the prevalence of fascioliasis in slaughtered cattle in Kangwon (Wonju, Hoengseong, Hongcheon, Cheorwon, Pyeongchang) province and Daejeon from October to December in 2014. From the total 10,780 examined cattle, 0.54% (58/10,780) were found to be positive for fascioliasis by postmortem macroscopic inspection. The Fasciola spp. infection rates were higher in the most Daejeon (1.83%, 41/2,240), followed by Hoengseong (0.40%, 15/3,714) and Hongcheon (0.22%, 2/901). It was not infected in the other regions. The outward appearances of Fasciola spp. infected livers looked almost normal and the worms were all parasitize in the main hepatic duct.

  • 본 발표에서는 3차원 안테나 유도 방식(3DAI)의 대기압 플라즈마 발생기술을 소개하고 그 응용에 대해 논의하고자 한다. 3DAI (3 Dimensional Antenna Induced) 방식의 가장 큰 특징은 하나의 전원 장치로 아크 발생 없이 다수의 금속 전극에서 플라즈마를 발생 할 수 있다는 특징과 3차원과 같은 높이 100 mm 이상의 큰 volume에서 플라즈마를 발생할 수 있는 기술로 그 적용을 확대할 수 있을 것으로 기대되는 기술이다. 다수의 금속 전극에서 플라즈마를 발생 시키는 기술은 대면적 처리가 가능하다는 의미이며 금속 전극을 사용한다는 것은 반 영구적 전극 사용을 할 수 있다는 의미로 해석할 수 있다. 본 연구에서는 신발 접착에 필요한 플라즈마 처리면적 350 mm, 플라즈마 발생 높이 100 mm급 3DAI 대기압 플라즈마 발생 장치를 개발하였다. 개발된 3DAI 플라즈마 기술을 이용하여 신발 재료 접착에 적용하였다. 화학 약품인 프라이머를 사용하지 않고 수성접착제를 사용하여 밑창인 고무와 중창인 IP 및 PU 등에서 모두 초기 접착 강도 1.5 kg/cm 이상, 경시 접착강도 3.5 kg/cm 이상으로 모재가 대부분 파괴되는 접착 강도를 얻었으며, 접착 수율이 99.9% 이상의 높은 생산성을 보여주고 있다.

  • The military remains have a social and historic value in holding up a true mirror to modern history of war and suffering, and will be used for historic place in Korea. This study is to research these modern military remains as cultural properties in Korea. They are classified with three types, namely military sites, installations of civil structures and buildings. The military remains have the historic sites of the righteous army and Korean war, and most of them are battle fields located in a mountainous area rather than urban area. There are fortresses, bridges and tunnels, and watchtowers of civil structures. The fortresses were constructed with Japanese military installations in the end of the Pacific War, and are most located in Sangmo-ri, Daejeong-eup, Seogwipo-si, Jeju-do, Korea. The bridges were to be destroyed and constructed during the war, and the watchtowers as military defence were to be constructed in inland area. There are arsenals, barracks, and headquarters of buildings. The weapon factory of Gigiguk (arsenal bureau) constructed in the late 19th century are present, and also the army training center, barracks, and church, etc are in Seogwipo-si, Jeju-do, Korea. There are old headquarters constructed in 1910s at Jinhae Gyeongnam, and buildings to testify about the horrors of the Korean war around Cheorwon, Gangwon.

  • In this paper, we developed a new method estimating the location of ballistic missile launching using infrasound signals. Infrasound signal generated from the North Korea's ballistic missile launch was used as source data and its signal was recorded at KMA (Korea Meteorological Administration) infrasound stations located at Cheorwon and Yanggu. Time-frequency analysis, TDOA (Time Delay of Arrival) method and spherical trigonometry were applied for data processing of signal recorded and occurrence location detection. We could confirm the outstanding performance of the algorithm estimating source location which was only 3 km apart from the actual launching site.

  • This study tried to reveal incision rate and its change by formation of lava plateau in the Cheorwon-Jeongok area. Incision rates of 0.421 m/ka and 0.101 m/ka in the upper and lower reaches of Hantan-gang, respectively, were calculated from sites before formation of lava plateau. These incision rates indicate that the upper and lower reaches of Hantan-gang have much higher and slightly lower incision rates than streams with similar distances from the Taebaek Mountains. However, sites after formation of lava plateau mostly showed incision rates ranging from 0.5 m/ka to 0.9 m/ka. Streams flowed on the lava plateau revealed 2-3 times higher incision rates than unrelated-streams or paleo-streams to formation of lava plateau did. These results suggest that incision rate in the study area was greatly influenced by formation of lava plateau and resultant geomorphic avulsion with rearrangements of stream.

  • To investigate the air mass modification related with Yeongdong Heavy snowfall events, we examined sensible and latent heat fluxes on the East Sea, the energy exchange between atmosphere and ocean in this study. Sensible and latent heats were calculated by a bulk aerodynamic method, in which NCEP/NCAR reanalysis data and NOAA/AVHRR weekly SST data with high resolution were used. Among winter precipitation events in the Yeongdong region, 19 heavy precipitation events $(1995{\sim}2001)$ were selected and classified into three types (mountain, cold-coastal, and warm types). Mountain-type precipitation shows highly positive anomalies of sensible and latent heats over the southwestern part of the East Set When separating them into the two components due to variability of wind and temperature/ specific Humidity, it is shown that the wind components are dominant. Cold-coastal-type precipitation also shows strong positive anomalies of sensible and latent heats over the northern part and over the central-northern part of the East Sea, respectively. It is shown that the sensible heat anomalies are caused mostly by the decrease of surface air temperature. So it can be explained that cold-coastal-type precipitation is closely related with the air mass modification due to cold air advection over warm ocean surface. But in warm-type precipitation, negative anomalies are found in the sensible and latent heat distributions. From this result, it may be postulated that warm-type precipitation is affected by the internal process of the atmosphere rather than the atmosphere-ocean interaction.
