This research was performed to determine the proximate compositions, mineral contents, alginic acid, antioxidative activities and amino acids of sea tangles collected from Gijang and Wando area. Crude protein and ash contents were higher in Gijang sea tangle, whereas carbohydrate and moisture were higher in Wando in general. Mineral contents of Gijang sea tangle were higher than Wando. Especially, Na and K was the most abundant in both Gijang and Wando sea tangles. Alginic acid content was almost similar in both sea tangles. The major free amino acids were glutamic acid, aspartic acid, alanine, proline and hydroxyproline in both Gijang and Wando sea tangles. Antioxidative activity of methanol extract of sea tangle was measured by using DPPH radical scavenging and SOD-like activity. DPPH radical scavenging and SOD-like activity were about 17% ($40\;{\mu}g/ml$) and 7% ($5\;{\mu}g/ml$) higher, respectively, in Wando sea tangle. When stimulate the macrophages RAW264.7 cells with lipopolysaccharide (LPS), inhibition of NO synthesis of the methanol extract was 11% higher in Wando sea tangle comparing with Gijang samples.

Until a recent date Wan-do Port has made efforts to advance its marine policy toward the base of marine distribution industry. Therefore the administration of Wan-do port has carried out many projects on improvements of harbour system very actively. The improvement of ship traffic system would be one of them. This research examined the general view of present situations of marine traffic system in Wan-do waters area and suggested improvements in ship route and anchorage.

The purpose of this study is to examine the determinant factors of satisfaction and to investigate the difference from clusters in the category of overall state of satisfaction, the thought of revisiting, and the intention of recommendation with the case of Wando Changpogo Festival. Changpogo Festival has been held since 1996 with the theme of 'Changpogo', gained great acknowledgment from television drama, 'Haeshin', and this year of 2009 is its fourteenth. The study analyzed questionnaire which is made up of items on satisfaction factors of 18 local festival visitors. Results from factor analysis are 1) the contents and the souvenir of the festival, 2) work for publicity, 3) tour for near place and convenient facilities. Likewise, results from cluster analysis are 1) a cluster of the contents and the souvenir of the festival, 2) a cluster of tour for near place and convenient facilities, 3) a cluster of work for publicity. In conclusion, there are similar degrees in difference between clusters, but especially the 'tour for near place and convenient facilities' factor has higher score than the others. Therefore, this factor should be cared with great importance.

The sea traffic volume in Southwest sea including Wando area have increased every year. However the improvement of the facilities for convenience and safety in port and sea was not enough to meet the increasing demand of traffic and passengers' need. This study dealt with the situations and status of passenger ship traffic system in Wando area. In addition to, questionnaire survey of passenger ship user in Wando area was carried out in order to research the improvement of marine traffic system. On the basis of the result, navigation risks in the area was analysed. The institutional system such as passenger ship fare, enhanced traffic system that can improve marine traffic environment in the area were suggested and examined. The urgent issue was the scattered fishing ground near fairway which makes narrow passage and can cause risky passeger ship's navigation. In the side of passeger ship's operation, the wage of cargo handling was relatively expensive that needed to be improved.

This study is the investigation of the tree type of six waterlogged archaeological wood excavated from the remains related to Yun Sundo in Bogildo, Wando Island; the remains had been excavated and surveyed by Jeonnam Cultural property Research Center. The identification result was four Pinus sp. (hard pine), one loquat and one Symplocaceae. All the identified tree types are subtropical ones and they are common in Bogildo, Wando Island.

Macroinvertebrates in forest streams affect the overall health of other streams in the same water system. In this study, we compared differences in the benthic macroinvertebrate community at two headwater streams located at different latitudes in the southern and northern parts of South Korea. We calculated the community temperature index (CTI), which represents the thermal preferences of the benthic communities. Hierarchical cluster analyses (HCA) were conducted to compare the similarities among sampling sites. In addition, we analyzed the relationship between community composition and environmental and community characteristics using non-metric multidimensional scaling (NMDS). Our results showed that CTI was significantly different between the two regions, indicating that these benthic macroinvertebrate communities have different thermal preferences. These two regions were clearly distinguished from each other in the HCA; furthermore, seasonal differences in benthic community composition were observed within each region. The functional feeding groups present in the benthic macroinvertebrate communities were different even though their habitat was similar.

Thirty one morphometric characters of striped field mice(Apodemus agrarius) from eight localities in Korea were analyzed by multivariate methods in order to confirm taxonomic status of specimens from Wando island. Two subgroups were recognized: a small-size form from six localities (Mt. Taebaek, Mt. Weolak, Cheongju, Mt. Chiri, Kunsan, and Jin isoland) and a large-size form from Wando island and Cheju island. It is confirmed that the small-size form from six localities is A. a. coreae, as described by Thomas(1908), and that the large-size form from Cheju island is A. a. chejuensis, as named by Johnson and Jones (1955). Furthermore, it is confirmed that large-size specimens from Wando island is and Cheju island. It is confirmed that the small-size form from six localities is A. a coreae, as described by Thomas(1908), and that the large-size form from Cheju island is A. a. chejuensis, as named by Johnson and Jones(1955). Furthermore, it is confirmed that large-size specimens from Wando island is subspecies A. a. chejuensis, as suggested by koh (1989). In future, analyses with specimens from islands in southern coasts are necessary to clarify the taxonomic status of Apodemus agrarius in Korea.
