  • An investigation of fish fauna was conducted based on the specimens from the Taean International Marine Park, off West Coast of Korea in 2005. They were collected by small seine net and stake net. The collected fishes were composed of 27 species belongs to 15 families and 8 orders. The dominant species were gobids of Favonigobius gymmnauchen in the sand area, Chamichthys gulosus and C. dolichognathus in the rocky area. The Korean endemic species were two species of Zoarchias uchidai and Repomucenus koreanus. But Porocottus leptosomus that described as a new species on the basis of specimens collected from this area in 2002 was not collected in this study.

  • The species and size compositions of fishes in the coastal waters off Taean were determined using samples collected with a two-sided fyke net in 2008. A total of 22 species, 2,371 individuals and 1,351 kg of fish were collected during the study. Of the fish collected, semi-benthic fishes such as Sebastes schlegelii, Mugil cephalus and Chelon haematocheilus were the most abundant (77.5% and 76.4% for total number of individuals and biomass, respectively). Benthic fishes such as Pleuronectus yokohamae and Paralichthys olivaceus were collected in almost all seasons but were low in abundance (5.3% and 4.1% for total number of individuals and biomass, respectively). Seasonal migrants were plentiful; specifically, Seriola quinqueradiata was abundant in November while Konosirus punctaus was common in July. Seasonal migrants of small-sized fish have been known to be abundant in the coastal water of western Korea including the study area, but few fish less than 100 mm were collected due to the large mesh size (30 mm) of the net used.

  • Hazardous chemicals, such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs) and heavy metals, are known as being harmful to human health were included in oils released by the Herbei Spirit Oil Spill accident in December 2007. To investigate changes of eating habits by the exposure to harmful substances, we conducted 5 focus group interviews for residents at Taean coast areas, who had experienced the oil spill accident. Participants included 46 women (mean age: $57.2{\pm}10.9$) who were mainly responsible for preparing family meals. Focus group discussions were audio-taped, transcribed and categorized by themes. Participants expressed more frequent illness symptoms such as dizziness, vomiting, visual loss, and skin diseases after the accident. They mentioned that their worries about economic hardship and worsened health status since the accident induced mental problems, such as depression about their children. Regarding eating habits, participants reported less intakes of fishes and meats and relatively more intakes of vegetables and kimchi due to the lack of household incomes after the accident. Although the participants had been used to collecting or catching fish or shellfish for their consumption previously, they mainly purchased these foods from local markets after the accident. Changes of eating habits induced by the accident included drinking boiled water and having steamed or fried seafood rather than raw seafood. Changes of food intakes occurred less frequently in older adults due to their longterm fixed eating habits, although they felt uncomfortable for having raw fish. The findings of this study clearly present that the exposure of hazardous substances by the oil spill accident had a significant impact on changes in eating habits besides economic, physical, and mental problems among the residents in Taean. Continuous health and nutrition monitoring and support are needed.

  • The issue of acid precipitation and related environmental problems in East Asia has been emerging. To evaluate the acidity and chemical characteristics of rainwater in Korea, its chemical properties during cultivation season from April to October in 2005 were investigated at Taean. Also, to estimate the contribution of ions on acidity, ion composition characteristics and neutralization effects by cations were determined. The electrical conductivity balance between measured and estimated values showed a high correlation. Rainwater was highly distributed in the range of pH $4.5{\sim}5.0$. The acidity of rainwater was relatively low during the month of June compared with other monitored periods. $Na^+$ was the main cation, followed by $H^+>Ca^{2+}>NH_4^+>K^+>Mg^{2+}$. Among these ions, $Na^+,\;NH_4^+,\;Ca^{2+}$ and $H^+$ comprised over 94% of the total cations. Rainwater anion composition was more than 80% with $SO_4^{2-}$ and $NO_3^-$. In rainwater samples, $NH_4^+$ and $Ca^{2+}$ contributed greatly to neutralizing the rain acidity. The sulfate content decreased until September, and sea salt derivatives were higher in May and October than during other monitored periods. Also, 78% of the soluble sulfate in rainwater was nss-$SO_4^{2-}$ (non-sea salt sulfate).

  • In this study, the soil characteristics of peat layer in Korea were analysed to predict new peat distribution areas in Taean, Chungcheongnam-do. The soil characteristics of peat distribution areas in Taean were compared with those in other areas in Korea. In Korea, peat researches were conducted in various regions, such as Taean in Chungcheongnam-do, Pyeongtaek in Gyeonggi Province, Gangneung in Gangwon-do, Ulsan, Iksan in Jeollabuk-do and Jangheung in Jeollanam-do. We summarized a) topographic distribution, b) deposition type, c) soil drainage classes, and d) soil suborder of previously studied area to determine criteria for prediction of peat distribution area. Through a case study, the type of peat layer distribution area in Taean were divided into two; (1) a) valley, b) co-alluvium, c) somewhat poorly drained, d) aqualfs and (2) a) marine plain, b) alluvium, c) very poorly drained, d) aquepts. A field survey was conducted to confirm the distribution of the actual peat layer. All peat layer were located within 10-km from the coastal line which is similar to previous studies, and the peat layer was characterized with pH 5, humic acid content of less than 15% and dark brown color. The new peat layer in Taean was deeper, thicker and less humificated than other studied areas.

  • This study used text mining methodology to focus on the perceptions of the landscape embedded in text that users spontaneously uploaded to the "Taean Travel"blogpost. The study area is the Taean Coast National Park. Most of the places that are searched by 'Taean Travel' on the blog were located in the Taean Coast National Park. We conducted a network analysis on the top three places and extracted keywords related to the landscape. Finally, using a centrality and cohesion analysis, we derived landscape perceptions and the major characteristics of those landscapes. As a result of the study, it was possible to identify the main tourist places in Taean, the individual landscape experience, and the landscape perception in specific places. There were three different types of landscape characteristics: atmosphere-related keywords, which appeared in Kkotji Beach, symbolic image-related keywords appeared in Sinduri Coastal Sand Dune, and landscape objects-related appeared in Manlipo Beach. It can be inferred that the characteristics of these three places are perceived differently. Kkotji Beach is recognized as a place to appreciate a view the sunset and is a base for the Taean Coast National Park's trekking course. Sinduri Coastal Sand Dune is recognized as a place with unusual scenery, and is an ecologically valuable space. Finally, Manlipo Beach is adjacent to the Chunlipo Arboretum, which is often visited by tourists, and the beach itself is recognized as a place with an impressive appearance. Social media data is very useful because it can enable analysis of various types of contents that are not from an expert's point of view. In this study, we used social media data to analyze various aspects of how people perceive and enjoy landscapes by integrating various content, such as landscape objects, images, and activities. However, because social media data may be amplified or distorted by users' memories and perceptions, field surveys are needed to verify the results of this study.

  • This study was carried out to investigate the chemical properties of rainwater in the Suwon and Taean areas. Rainwater was collected during the farming seasons of 2002 and 2003. The number of samples collected in Suwon and Taean were 69 and 71, respectively. These were analyzed for chemical composition. The pH of samples collected in April was higher than those collected after June. The most common range of rainwater pH was 5.0-5.6 in Suwon and 4.5-5.0 in Taean during investigation periods. The neutralization capacity of rainwater acidity by $Ca^{2+}$ and N $H_4$$^{+}$ was decreased during the rainy season. The EC of rainwater was lower during the rainy season. Cation concentrations in rainwater were N $H_4$$^{+}$ > $H^{+}$ > $Ca^{2+}$ > $Mg^{2+}$ > $K^{+}$ in Suwon and $Ca^{2+}$ > N $H_4$$^{+}$ > $H^{+}$ > $K^{+}$ > $Mg^{2+}$ in Taean. In the case of anion, the order was sol > N $O_3$$^{[-10]}$ > C $I^{[-10]}$ in Suwon and S $O_4$$^{2-}$ > C $I^{[-10]}$ > N $O_3$$^{[-10]}$ in Taean. The mean values of sulfate in rainwater were 130 $\mu$eq $L^{-1}$ in Suwon and 117 $\mu$eq $L^{-1}$ in Taean. The ratio of non-sea salt sulfate to sulfate (nss-S $O_4$$^{2-}$ > S $O_4$$^{2-}$) was 89% and 88%. This implies that the major origin of sulfate in rainwater might be anthropogenic.ht be anthropogenic..

  • The atmospheric deposition flux was measured with dustfall from July of 1997 to July of 1998 at nine sampling sites located in Tae-an peninsula to examine the seasonal variations. The results showed that the average dry deposition was higher in spring than the other seasons. Thus, it is considered that yellow sand is one major source of the additional deposition flux in spring. There also appeared the higher measurement of deposition at the sites nearby road (like Hagampo, Bangali and Sinduri) in summer, and it is assumed that the heavy traffic caused by summer visitors was the main factor of that. For more accurate study, the qualitiative analysis should be taken on the deposited materials.
