This study was carried out to survey the pollution of nonvlphenol (NP) in surface sediments around Gwangyang bay and Yeosu sound. NP was suspected chemicals as endocrine disruption. Gwangyang bay is located on the mid south coast of Korea. It is a semi-closed bay which Yeosu petrochemical industrial complex, POSCO (Pohang Steel Company) and Gwangyang container harbor are there. The surface sediments were collected at 15 stations with gravity corer at October, 1999, February, May and August, 2000. Also, the stream and intertidal sediment were collected at 5 sites at August, 2000. Concentrations of NP in surface sediments were in the range of 6.89 to 202.70 ng/g dry wt.. Seasonal range (mean value) of NP is 13.98 to 30.48 (23.46) ng/g dry wt. at October, 10.35 to 54.91 (28.10) ng/g dry wt. at February, 29.05 to 202.70 (82.32) ng/g dry wt. at May and 6.98 to 83.40 (25.37) ng/g dry wt. at August. NP was seasonally fluctuated, and the highest mean value and range was detected at May, 2000. NP was highly distributed in the inner part of Gwangyang bay than Yeosu sound. Concentrations of NP in stream and intertidal sediments showed the highest value in downstream near Yeosu petrochemical industrial complex and Yondung stream. It suggests that the source of NP is industrial wastewater and municipal sewage.

A variety of factors influence traveller's destination choice. In general, these factors can be placed along a continuum ranging from the concrete or tangible attributes of the destinations at one extreme to the abstract or intangible benefits, needs, or motivations travelers to be satisfied with the other extreme. Especially for choosing a resort destination located at overseas, these aspects of factors form the critical basis on traveller's resort selection attributes. Nevertheless, researchers stated even though overseas resort market is rapidly growing, there are not enough studies about resorts and resorts selection attributes. Relatively little research has been carried out on overseas resort selection attributes with multi-dimension scales method. Therefore the primary purpose of the study is to know the tourist's awareness of overseas resort' characteristics. The second purpose is to comprehend similarities of wine producing countries based on five-resort selection attributes and draw positioning map using MDS(Multi-dimension Scale). The questionnaire was composed of 4 types of questions including demographics questions and general feature of resort tourist. How 25 resort selection attributes influence when tourist choose resort and lastly how resort selection attributes influence 10 overseas resorts. The questionnaires was aimed at tourists who currently staying in resort, and requirement were tourist visited 3 resorts or more in the study.

This study was performed to characterize the water quality of Doam bay from March 8 to August 16,1997. Doam bay is located in the western part of south coast in Korea. The results are as follows: The northern part of surveyed area was highly effected from the freshwater of Tamjin river by the results of salinity and pH. Dissolved oxygen(DO) concentrations were slightly under saturated in the bottom layer at August, but more saturated at spring season. Ranges of suspended solid(SS) concentrations were 6.57~67.50mg/l, and showed the showed the highest mean values in bottom layer at June. Chemical oxygen demand(COD) concentrations showed the highest mean value of 1.98mg/l in surface layer of June. Dissolved incorganic nitrogen(DIN) concentrations showed the highest mean value of 2.97㎍-at/l in surface layer at May, while showed the lowest mean value of 0.92㎍-at/l in bottom layer of June. Dissolved inorganic phosphorus(DIP) concentrations was in the range of 0.06~3.18㎍-at/l. The highest mean value of 1.90㎍-at/l was in bottom layer of June. And, higher concentrations were showed in the northern inner area. Nitrogen is more limiting constituednt than phosphorous in the growth of phytoplankton in almost all area at all surveyed season by the results of lower N/P ratio than 16 of Redfield ratio. Eutrophication indices were slightly high in the northern inner area at May and June. But, they were lower in the other almost surveyed area.
