Two species of fusulinids, viz., Pseudoschwagerina paraborealis and Quasifusulina sp. are described from the limestone core sample(90-B-1). The core sample was obtained from Imgokri, Boeungun, Chungcheongbukdo, Korea. Recognition of Pseudoschwagerina helped the authors to establish the Pseudoschwagerina Zone. Pseudoschwagerina paraborealis has been reported from the Bamchi Formation of Yeongweol coalfield in Korea and also from the Asselian and Sakmarian strata in Eurasia. The occurrence of Pseudoschwagerina paraborealis in the Boeun coalfield demonstrates the existence of the early Permian strata that are equivalent to the Bamchi Formation of Yeongweol coalfield. The authors report Quasifusulina sp. which indicates the early Permian period as well as Pseudoschwagerina paraborealis. It is the first time that the species of early Permian fusulinids are identified from the Boeun coalfield.

As social diversity is increased recently, conflict between government and non-government organizations is also being increased. This conflict disturbs social development and also social cost to solve the conflict is very high. Therefore, it is necessary to set up a mediation organization which can draw reasonable decision making while minimizing social conflict. In this study, we compares Samangeum reclamation project and Youngweol dam case to find out how their recognition framings are formed, confronted, or adjusted and also how the process affects their conflict.

The purpose of this study is to investigate and analyse the opinions of tourists and local commercial residents for remodelling of Youngwol Gossi-cave area so that to find the way how to activate it. Therefore this study has been focused on the opinions of tourists to visit it, local merchants to sell goods and foods and officers to take charge of the control office. The present conditions of Gossi-cave area are stagnated since the service level is low by the excessive competition among the local merchants. As a result, the inner troubles have arisen among the local merchants. Therefore firstly the sustainable and future-oriented remodelling development of Youngwol Gossi-Cave area is required. And then the basic remodelling plan of participant type to be centered with tourists and local residents as the central figures through local residents' ability strengthening must be established. Lastly the basic remodelling plan through the connection of surrounding tour resources and the resource increase of local amenities must be established. Also it is necessary for the conversion as a tour place of sojourn by supplying with various shows through connections among surrounding tour resources worthy of seeing and the creation of concept to provide the excitement through the education and experience in a basic remodelling plan direction of Youngwol Gossi-cave area.

Pre-monsoon dynamics of zooplankton community were investigated in Yongwol West River tributary; wetland shaped Korean Peninsula. Zooplankters were collected at three sites (stn 1: Yongwol West River, stn 2: Pyungchang River, stn 3: Jucheon River) monthly during the period between March and July 2014 except April. Totally 58 taxa of zooplankton occurred, consisting of 27 species of rotifer, 18 species of cladoceran, eight species of copepod, four kinds of aquatic insect larvae and one nematod. Lotic cladocerans of Alona spp. belonging to Chydoridae occurred frequently while typical lentic ones of Bosmina spp. and Daphnia spp. were not distributed, then sampling sites may be located in lotic waters. Zooplankton abundance recorded as $4,451-8,011indiv{\cdot}m^{-3}$ in Jucheon River but never exceeded $500indiv{\cdot}m^{-3}$ in other rivers. In Yongwol West River, dominant taxa were aquatic insect larvae from March through June and succeeded to cladocerans and copepods in July. Similar succession was observed in Jucheon River where aquatic insect larvae dominated in March and changed to cladocerans and copepods from May with high abundance. No such succession of zooplankton community was detected in Pyunchang River. Species diversity indices were the highest in Yongwol West River except in March. High values of dissolved oxygen ($9.0-11.0 mg{\cdot}liter^{-1}$) may show the characteristics of mountain streams. Water temperature increased gradually from $10.1^{\circ}C$ to $27.9^{\circ}C$ and pH varied within generally high range between 7.9-8.9, respectively. High value of pH seems to be derived from lime stone mines and cement factories around the studied area.

This study estimates the WTP for the plan of solving deforestation due to limestone mining and calculates that damage cost using contingent valuation method. As the results of analysing a dichotomous choice CV data, the yearly mean WTP per household for the plan is 5,045 won(95% confidence interval : 3,729~6,360 won) in single bounded CV model and is 4,361 won(95% confidence interval : 3,710~5,012 won) in double bounded CV model. The damage cost of deforestation due to limestone mining can be estimated as 55.3% of WTP for the plan which is assigned to restoring the deforestation area to the original or similar alternative state. The average yearly deforestation cost of 1 ha due to limestone mining is reached 20.90 million won(95% confidence interval : 16.53~25.27 million won). And the asset value of that 1 ha damage is 160.02 million won(95% confidence interval : 126.56~193.49 million won). The fact is found that the damage cost of deforestation using replacement cost method is likely to be underestimated. The total damage cost of deforestation because of limestone mining in 3 cities (Donghae, Samcheok, Yeongwol) is 204.0 billion won(95% confidence interval : 161.4~246.7 billion won) which is composed of 26.5% for Donghae, 28.9% for Samcheok, and 44.6% for Yeongwol according to the damage size of deforestation due to limestone mining in 3 cities.

This study describes the processes undertaken for the conservation treatment of metal artifacts excavated in Hasong-ri, Yeongwol, Gangwon-do and the results of the related surface composition analysis. X-ray fluorescence analysis (XRF) was applied to analyze the surface composition of a small gilt-bronze wind chime, two clappers, and a small gourd-shaped bronze bottle. The gourd-shaped bronze bottle was investigated using radiography to examine its internal structure. The wind chime and clappers were excavated from the same location. A gilt layer was identified on the wind chime, but surface corrosion made it difficult to identify any such layers on the clappers. The element analysis revealed that the wind chime was made of bronze in a Cu-Sn-Pb ternary system and was gilt-plated using mercury amalgam. The clappers were made from copper with a small amount of gold detected, but did not show any evidence of mercury. Since a thick corrosion layer was affixed to the surface of each clapper, it was impossible to identify the surface composition and determine if the clappers had been gilded. It is possible that the gold detected from the clappers was a foreign substance or had detached from the giltbronze wind chime buried alongside them. The small gourd-shaped bronze bottle was investigated through surface element analysis and radiography to verify if it was a type of silver bottle used as currency during the Goryeo dynasty. The radiography photography identified that a small hole in the middle of the base had been stopped up. The general surface analysis did not detect silver, which suggests that the bottle was made of bronze instead and was not one of the silver bottles used as a means of currency.

Analysis of the fish community in Yeongwol Hanbando wetland in Korea was investigated from April to October 2012. During the survey period, total 33 species belonged to 10 families and 7,107 individuals. There were 18 Korean endemic species (52.94 %), including to Acheilognathus signifer. Also, the dominant species were Zacco koreanus at St. 1, 2, 3 & 5, as well Acheilognathus signifer at St. 6, and Pseudopungtungia tenuicorpus at St. 7, respectively, and these species were inhabited in the midstream. But at St. 4, Carassius auratus was dominance, so there appeared to characteristics of downstream or lentic habitat. Also, according to the similarity analysis on fish species and their individuals in each sites, they were divided into three major groups (A,B and C). Among them, group C (St. 4) showed the special inverse characteristics as a stagnant pond. unlike the river branch (group A) and anthropogenic disturbances receiving stream point (group B), Therefore, the ecosystem of Yeongwol Hanbando wetland is considered to very unique and these characteristics are not found in other stream ecosystems and it is confidently believed that the ecological value is very high.
