This study was performed to observe the infection status of sweetfish, caught from Kwangjung- stream and Namdae-stream in Yangyang-gun, Kangwon-do in August 1989, with the metacercariae of Metagonimus yokogawai. All of 28 sweetish from Kwangjung-stream were infected with the metacercariae of M. yokogawai. The number of metacercariae in a fish ranked 89-521(224 on average), and the number of larvae/g of mesh was 12-55(22 on average). On the other hand, no metacercariae were detected in the fish from Namdae-stream. It has been confirmed that the Kwangjung-stream in Yangyang-gun, Kangwon·do is one of the endemic foci of metagonimiasis in Korea.

Yangyang Gangwon-do has begun the clearing of upland forested areas for development. This process has caused great damage from natural hazards such as landslides and flooding for many years. Moreover, proper hazard prevention strategies have not Yet been prepared. To provide useful information for developing hazard prevention strategies this study attempted to detect areas vulnerable to flooding in Yangyang using data such as topology, meteorology, history, land use, soil, hydrology, and society. It was found that roughly 30% of the study area was vulnerable to flooding. Also it was discovered that where the vulnerability index was high, there was increased amounts of flooding. The most vulnerable areas were where forests were cut and near livers. In addition, areas where frequent hazard events were reported had a high index of vulnerability. The results of this study will provide useful information in developing hazard prevention strategies.

This study analyzed the repeated causes of policy failure focusing on Yangyang International Airport cases. Yangyang International Airport, which opened in 2002, was built with about 360 billion won, but it is considered as a representative example of policy failure of local airports. According to the policy failure theory, the failure factors of Yangyang International Airport are anlyzed by rationalistic, political, and environmental complexity viewpoint. The results are as follows. First, from a rationalist point of view, Yangyang Airport failed to achieve the policy goal of securing passengers and revitalizing local economy, This is due to the pressure of politics and the lack of geographical infrastructure. Second, the failure of the stakeholders to resolve conflicts in the flow of politics can be seen as the conflict between the airline and the airport, and the failure to reconcile conflicts between the government and the airports on the low cost airline permits and subsidies. Third, from the viewpoint of environmental complexity, Yangyang International Airport can be regarded as a failure to adapt to environmental changes such as the opening of nearby expressways and railway lines, and the sharp decline of Chinese tourists. This study sugeests the establishment of an independent organization that can prevent unreasonable business promotion by politics in the case of large scale national projects, the linkage with the surrounding infrastructure and related businesses in the case of transportation facilities such as airports and railways, and institutionalization of cooperative governance for coordinating conflict among stakeholders.

Dam construction in a river can change its hydrological pattern and trap sediments, which results in ecological changes in the downstream. It is a common phenomenon in the downstream of dams to have decreased sediment flow and increased periphyton. Artificial floods and sediment application are suggested as mitigation practices in order to simulate natural process of flood; transporting sediment and sloughing periphyton off. In this study the effects of artificial floods on periphyton were examined by applying sand artificially and discharging water from a dam (Yangyang Dam, Korea). The study area has been suffering from turbidity problems caused by shore erosion of the dam. The accumulation of inorganic sediments and increase of periphyton on the river bottom are the major factors of habitat deterioration in the downstream reaches. Artificial flood and artificial addition of sand was performed in summer and the effects were measured. Piles of applied sands were washed off easily by discharge and it enhanced the periphyton sloughing effect. The removal efficiency of periphyton was 50 ~ 80% within the 2 km reach from the dam. In conclusion artificial floods and sand application can be a good mitigation measure for the habitat rehabilitation after a dam construction in streams.

Earthquake records written in the history documents such as “SeungJeongWon IlKi” and “Chosun Wangjo Shilok” for the earthquakes occurred around the offshore near Yangyang and Samcheok area in June, 1681, have been analyzed to estimate the intensity distribution and epicenters as well as magnitudes. Three consecutive earthquakes were analysed, which occurred near those area on June 12, 17, and 26, 1681. The Main-shock occurred on June 12, 1681 was felt in almost every provinces of Korea while after-shocks occurred on June 17 and 26, 1681, were felt in several provinces restrictively. Although the main-shock was felt in the entire provinces, the real damage had been concentrated in Kangwon province. A block of rock collapsed to fall due to main-shock in the mountain near Samcheok. No other man casualties were reported except a death due to being thrown off a horse by ground shaking in Seoul. Local micro-tsunami seems to be generated at the offshore of Samcheok due to the main-shock. The main-shock seems to be occurred in the offshore between Yangyang and Samcheok (38.0oN and 129.0oE) , the epicenter intensity and magnitude of which is over 8 in MMI and 6½ in Ms, respectively.

This study investigated the proximate composition and total amino acid contents in Tricholoma matsutake and Sarcodon aspratus to compare the food quality according to production area. The crude ash contents in Tricholoma matsutake from Yanji (China), Yangyang (Korea), Tibet (China), and Yunnan (China) were 6.95%, 6.40%, 5.52%, and 5.40%, respectively. Yangyang showed the lowest crude fat content (1.19%), whereas Tibet exhibited the lowest crude protein content (16.83%), showing a difference according to the production area. The total amino acid content of Tricholoma matsutake in Yanji, Yunnan, Tibet, and Yangyang was $11,490.14{\pm}892.07mg%$, $8,000.03{\pm}207.25mg%$, 6,815.48 mg%, and $6,074.74{\pm}814.86mg%$, respectively. The contents of proximate composition and total amino acids in Sarcodon aspratus showed no difference according to production area. The results of proximate composition in Tricholoma matsutake suggest that the crude ash content can be used as a distinguishing indicator between Tricholoma matsutake from Yangyang and Tibet. Further studies are needed to analyze the mineral contents for the establishment of distinguishing mineral indicators between Tricholoma matsutake from Yangyang and Tibet.

This study has been carried out to estimate aboveground biomass and net primary production(NPP) in an average 41-years-old Quercus variabilis stand of Gongju area, 45-years-old Quercus variabilis stand of Pohang area, and 54-years-old Quercus variabilis stand of Yangyang area. Ten sample trees were cut in each forest and soil samples were collected in July to August, 2000. Estimation for aboveground biomass and net primary production were made by the equation model $Wt=aD^b$ where Wt is oven dry weight in kg and D is DBH in cm. Total aboveground biomass was 91.31ton/ha in Gongju area, 207.6ton/ha in Pohang area, and 71.39ton/ha in Yangyang area. The aboveground biomass 207.6ton/ha in Pohang area is the highest biomass production among the amount of biomass in Quercus variabils stands reported in Korea. The proportion of each tree component to total aboveground biomass was high in order of bolewood, bolebark, branches and leaves in the three forests. Aboveground total net primary production was estimated at 7.8ton/ha in Gongju area, 11.5ton/ha in Pohang area, and 6.40ton/ha in Yangyang area. There were at least 2 times higher total aboveground biomass in Pohang area than in the Gongju and Yangyang areas because of climate difference among the study areas.
