여수 연안 정치망 어장의 주변 해역을 중심으로 1990년 4월부터 11월까지 매월 채집해서 분석한 식물플랑크톤의 분포량과 여수수협 위판장으로부터 구한 어획량 자료등을 이용하여 여수 연안 정치망 어장의 환경요인인 식물플랑크톤의 분포량과 어획량 변동과의 관계를 분석 정리한 결과를 요약하면 다음과 같다. 1) 식물성 플랑크톤의 출현량은 춘계와 추계보다 하계에 최대가 되고, 특히 육수의 유입이 많은 여수만 중 돌산연안 수역 분포량이 많고, 소리도와 세존도부근의 식물성 플랑크톤 분포량은 내만수의 확장 경향을 추정하는데 유익하게 이용될 수 있다. 2) 여수 연안 정치망에 어획되는 주요 어종의 어획량은 삼치, 갈치, 고등어, 정어리, 멸치, 전갱이 및 방어의 순이고, 어획되는 시기는 정어리와 멸치가 4~6월, 전갱이, 갈치 및 고등어는 6~10월이 였으며, 삼치는 전 어기에 걸쳐 어획되었다. 3) 여수 연안 정치망 어장의 어획량은 식물성 플랑크톤 출현량과 상관 관계가 있고, 이들 식물성 플랑크톤량은 하계 육수의 영향을 많이 받는 내만수에 최대의 출현량을 보인다. 또, 이 어장의 어획량은 하계에 많으므로 여수 연안 정치망 어장은 육수의 유입에 의해 풍부한 영양염류를 공급받는 내만수내의 이료생물의 생산력이 어획량을 좌우하는 어장의 중요한 환경요인이 될 수 있다

In order to investigate the environmental properties of set net grounds located in the coastal waters of Yeosu. The current in the vicinity of set net grounds was observed by drogue and current meter in 1990 and 1992. The results obtained are summarized as follows: The direction of tidal current at the north enterance of Yeosu bay was southerly in ebb and northwesterly in flood without the distiction of the neap tide and the spring tide. In spring tide the maximum Velocity of the tidal current was 68 cm/sec in ebb and 66 cm/sec in flood. In neap tide the maximum velocity of the tidal current was 37 cm/sec in ebb and 35 cm/sec in flood. And so the direction of residual current was the south ward mainly and 21 cm/sec. The direction of tidal current at set net fishing grounds was southwesterly in ebb and westerly or northwesterly in flood. Regardless of the distinction of neap and spring. The maximum velocity of the current in spring tide was 50 cm/sec in ebb and 40 cm/sec in flood and that in neap was 28 cm/sec in ebb and 25 cm/sec in flood. In spring tide the speed vector along the major axis of semidiurnal tide component was three times as large as diurnal tide. In neap tide, however, the speed vector was about 50% less then that in spring tide, and the semidiurnal tide and diurnal tide were equal in the size of current ellipse and the direction of major axis. The sea area had a southwesterly residual current. 11 cm/sec in spring tide and 7 cm/sec in neap tide. According to the result of drogue tracking, the vicinity of set net fishing ground had a southerly residual current which formed in Yeosu Bay and a weak westerly residual current toward Dolsando from Namhedo. Therefore, set net fishing ground in coastal water of Yeosu was distributed in boundary of inner water which formed from Seamjin river and offshore water supplied from the vicinity of Sorido and Yochido.

In order to investigate the relation between the environmental properties and catch fluctuation of set net fishing ground located in the coastal waters of Yeosu, oceanographic observation and catches on the grounds were carried out from Jan. to Dec. in 1990 and 1992. The results obtained are summarized as follows; 1) Because of the surveyed area is a costal shallow water, the fishing ground was influenced largely by atmospheric phenomena such as air temperature. precipitation. etc. and so showed large variations in temperature and salinity yearly. The inner water flowed out mainly between Yeosu ad Namhe-do, and then through Kumo-do between Dolsan-do and Kumo-do. On the other hand, off shore water was supplied into the fishing ground from the vicinity of Sori-do and Yokchi-do. thus the fishing ground was occupied usually by various sources of water. 2) The water mass in the fishing ground were divided into the inner water(29.0～30.6‰) and the mixed water(31,7～32.2‰) and off shore water(32.3～32.8‰) accourding to the distribution of salinity from T-S diagram plotted all salinity data observed in 1990 and 1992. In summer the inner and mixing water which was formed by river flowed southerly and spread south-easterly in the vicinity of Kumo-do. The off shore water which supplied from the vicinity of Sori-do and Yokchi-do and inner water formed the thermal front and halo front in summer. 3) The fishes caught by the set net were arranged in the order of catch amounts as follows: Spanish mackerel〉Horse mackerel 〉Hair tail〉Common mackerel〉 Sardine〉 Anchovy. The Catches of anchovy and sardine were high in April to May and those of hair tail and horse mackerel in July to September, but spanish mackerel were caught during the whole period of fishing. When inner water and mixing water appeared respectively and inner water and mixing water speared together in the set net fishing ground, the set net showed a high catch.

In order to investigate the environmental properties of set net grounds located in the coastal waters of Yeosu, oceanographic observations on the fishing grounds were carried out by the training ship of Yeosu Fisheries University from Jun. 1988 to Dec. 1990. The resultes obtained are summarized as follows; 1) The water mass in the fishing grounds were divided into the inner water (29.50-31.00‰), the mixed water (31.10-32.70‰) and the offshore water (32.70-34.30‰) according to the distribution of salinity from T-S diagram plotted all salinity data observed from Jun. 1988 to Dec. 1990. In spring the mixing water prevailed and in summer the inner and mixing water. But in autumn and winter the mixing and offshore waters prevailed. 2) The inner water which was formed by land water from the river of Somjin and the precipitation in the Yeosu district flowed southerly along the coast of Dolsando and spread south-easterly in the vicinity of Kumodo. The inner water and offshore water which supplied from the vicinity of Sorido and Yokchido formed the thermal front and halofront. 3) As the mixing water flowing from the western sea of Cheju to the southern coast of korea was low in temperature, the water mass of low temperature which appeared at the offshore bottom of Sorido in summer was considered not to be the Tsushima warm current. 4) As vertical mixing was made frequently in spring, autumn and winter, the differences in temperature and salinity between surface and bottom was respectively small. In summer, however, the mixing was not made because of the inner water expanded offshore through the space between surface and 10m layer and so a thermocline of 2.0℃/10m and halocline of 4.0‰/10m respectively in vertical gradient was formed. 5) In the vicinity of Dolsando and Kum a water low in salinity prevailed, but in the vicinity of Namhaedo and YoKchido the reverse took place. The inner and mixing waters formed at these arease was limited to the observation area not to spread widely.

The intertidal zone has both land and marine characteristics and shows complex weather environments. These characteristics are suited for studying climate change, energy balance and ecosystems, and may play an important role in coastal and marine weather prediction and analysis. This study was conducted at Odo Island, approximately 300m from the mainland in Yeosu. We built a weather observation system capable of real-time monitoring on the mud flat in the intertidal zone and measured actual weather and marine data. Weather observation was conducted from April to June 2022. The results showed changes in air temperature and water temperature with changes in the tide level during spring. Correlation analysis revealed characteristic changes in air temperature and water temperature during the day and night, and with inundation and exposure.

This study was conducted to determine physico-chemical properties and degree of heavy metal contamination of sediments collected at Yeosu harbor. Outside of harbor (Y1, Y2, and Y3) showed relatively lower ignition loss than those for Y4 and Y5. All sediment samples had similar oxides and minerals based on the XRD and XRF analyses. Heavy metal contamination of the sediments was evaluated using USEPA, Ontario sediment quality guidelines, index of geoaccumulation and total enrichment factor. In summary, sediment Y5 was classified as moderately contaminated region based on index of geoaccumulation and heavily polluted based on standards of USEPA, Ontario sediment quality guidelines, and total enrichment factor. Sample Y5 obtained from the inner side of harbor showed the highest heavy metal contents. Among five heavy metals measured at Y5, Cu concentration was extremely high, which indicated that harbor activity might influence the Cu concentration in harbor sediment.

Objectives: This study is aimed at identifying the influential factors on the pulmonary function of ordinary residents in the surrounding areas of Yeosu Industrial Complex. Methods: The PFT (Pulmonary Function Test) was conducted on the target residents numbering 989 people (male 361, female 628). The exposed group (813 people) resided within the radius of 5km from Yeosu Industrial Complex and the control group (176 people) resided in the radius of more than 15 km from May 2007 to November 2007. The survey also took into account other factors including personal characteristics, life habits, respiratory diseases and allergic symptoms, medical histories, and the living environments of the residents in order to further identify influential factors on pulmonary function. Result: When comparing the PFT values of the exposure groups to the control group of the same city, values of the exposure groups were meaningfully lower with an %FEV1 of 107.05% and %FVC of 100.28%. Conversely, the control group reported an %FEV1 and %FVC of 107.26% and 102.85% respectively, indicating that ambient air pollutants reduce lung function. The odds ratio of asthma diagnosis history increased when a subjects residence was close to a heavily trafficked road, traffic amount was huge, a bed was used, and the family had less than four members. However the results were not statistically meaningful. The odds ratios of abnormal pulmonary function were statistically higher among those with asthma(OR=4.29, CI=1.75-10.56), wheezing (OR=2.59, CI=1.24-5.41), and nasal congestion (OR=2.87, CI=1.36-6.08) (p<0.01). The factors affecting FEV1 were symptoms including asthma, passive smoking and allergic eye disease (R2=0.049, p<0.001). For the FVC symptoms including asthma (R2=0.014, p<0.001) were measured. The analysis showed that FVC decreased with increases in O3 and CO(p<0.01). Furthermore, FEV1 decreased with increases in O3(p<0.01). Conclusions: These results will provide preliminary data for establishing responsive measures to protect the health of residents in industrial complexes from air pollution, and to develop lasting environmental health policies.

The production of the sharp-toothed eel by commercial catch off waters of Korea is annually declined after 1978. This study was carried out to obtain the stock management of the sharp-toothed eel using the PCR-aided RFLP method. The mtDNA COI gene was amplified using species-specific primers and PCR product was observed to 700 bp. Amplified DNA fragments were treated with six kinds of restriction enzymes (BaeHI, EcoRI, PstI, Ksp22, HinfI and HaeIII). The treatment of HaeIII showed a distinct PCR product between Yeosu/Jinhae/Jeju/Goseoung and Jangheung/Haenam populations that were observed from 300 to 400 bp in reference to 100 bp molecular marker. However, DNA fragment within populations had an identical pattern. The phylogenetic homology is 82% between two populations inferred from RFLP PCR product pattern using NTsysPC ver. 2.1. The use of HaeIII plays an important role in discriminating populations. It is thought that adults after over-wintering in the southern part of Jeju migrate to the Yeosu, Jinhae and Goseoung regions to spawn instead of to southwestern waters. Individuals within populations showed a relatively active genetic mixing and migration regardless of geography. However, the genetic ancestor of Jangheung and Haenam populations is appeared to be more adjacent to China or Japan than Jeju.

The purpose of this paper is to estimate a probability to visit the Yeosu Aquarium with an ordered logit model. Ordered logit model is affordable to estimate the probability when the dependant variable represents likert-type scale. The estimated results are as follows. The more income induces the visiting-expectation. The experience for another aquarium and the visiting-expectation for the Yeosu EXPO are contributed to the visiting-expectation for the Yeosu Aquarium. The needs to visit the Yeosu Aquarium is low in Kyoungsang area and Seoul-Kyounggi-Incheun Metropolitan area. This is related to the Aquarium facilities, which were established in each area. In average level conditions regarding to all independent variables the probability to visit the Yeosu Aquarium is calculated to 15.75%. However, the probability to visit to the Yeosu Aquarium is decreasing according to the change of an admission fee.

이 논문의 목적은 21세기 BIE엑스포에서 주제와 메시지의 중요성과 역할이 무엇인지 규명하고, 주제와 도시개발에 초점을 두고 있는 2012년 여수엑스포 계획에 유용한 제언을 제공하는 것이다. 1998년 리스본엑스포를 전환점으로, 엑스포의 주제와 메시지는 과학기술의 성과를 강조하는 것보다는 진보에 대한 반성과 지구의 미래를 강조한다. 이러한 변화는 오늘날 인류 사회가 당면한 전지구적 환경문제의 해법 모색과 지속가능한 개발을 보장하는 신기술에 대한 관심을 반영한다. 바다와 연안에 대한 신기술과 신사상을 경연하는 여수엑스포는 비슷한 주제의 리스본엑스포의 사례를 벤치마킹하는 동시에 이와 차별화하기 위한 노력이 필요하다. 이 논문은 여수엑스포의 주제와 도시개발에 대해 다음과 같이 제안하였다. 첫째 해양과 관련된 신기술의 강조와 더불어 그것의 개도국 보급을 위한 여수프로젝트 비전의 강화. 둘째 리스본의 수도재개발과 다른 도시개발전략 즉, 남해안시대와 연계된 해항도시네트워크 구상.

Based on the monthly weather report of Korea Meteorological Administration (KMA) and daily sea surface temperature (SST) data from National Fisheries Research and Development Institute (NFRDI) (1995-2004), mean heat fluxes were estimated at the port of Yeosu. Net heat flux was transported from the air to the sea surface during February to September, and it amounts to 205 Wm-2 in daily average value in May. During October to January, the transfer of net heat flux was conversed from the sea surface to the air with -70 Wm-2 in minimum of daily average value in December. Short wave radiation was ranged from 167 Wm-2 in December to 300 Wm-2 in April. Long wave radiation (Sensible heat) was ranged from 27 (-14) Wm-2 in July to 90 (79) Wm-2 in December. Latent heat showed 42 Wm-2 with its minimum in July and 104 Wm-2 with its maximum in October in daily average value.
