  • The fourth industrial revolution introduced at world economic forum in 2016 has had huge effects on tourism industries as well as the change of core technologies in ICT such as big data, IoT, etc, This paper proposes the methods to propel tourism of Yoesu city through big data analysis and questionnaires. Sensitive words and positive-negative trend are extracted by Social Metrics and the keywords for Yeosu tour trends are extracted and analyzed by Naver datalab, and the results are visualized by R language. And frequency, difference, factor, covariance and regression analysis in SPSS are executed for the questionnaires for 493 visitors who traveled in Yeosu city. Sentiment analysis for Yeosu tour and maritime cable car shows that positive effect is much more than negative one. The analyses for questionnaires in SPSS show that Yeosu area is statistically significant to tour satisfaction index and tour revitalization for Yeosu, and favorite sightseeing places and searching electronic devices for age groups are different. The sightseeing places such as a maritime park with soft contents that give joyfulness and healing to tourists are highly attracted in both the big data and questionnaires analysis.

  • Physical and acoustic properties of sediment core samples recovered from the Kwangyang Bay, the Yeosu Sound, and the inner shelf of central South Sea, Korea were investigated. Compressional wave velocity, density, porosity, and shear strength were measured at 10cm interval's along the core depth. Sediment texture(grain size, sand, silt, and clay contents) were also measured and correlated with the physical properties(density, porosity, and shear strength). The physical and acoustic properties of the sediment changed gradually from the Kwangyang Bay to the shelf area in accordance with the distance from the input source of the terrigenous sediment. The Yeosu Sound acted as a route of sediment transport from the estuary(the Seomjin River) to the shelf and vice versa. The physical and acoustic properties of the Yeosu Sound sediment conformed to an intermediate stage between river mouth and shelf areas. These results can be utilized to trace the influence of the Seomjin River on the so-called mud belt of Korea.

  • This study was to analyze dynamics of host regional effect in accordance with Mega-events. Yeosu Expo, 2012 was the Mega-event, and dynamic changes in economic indicators such as number of tourists, GRDP, employment rate, and real estate price were analyzed before and after the event. The Mega-event affected positively and increased on the number of tourists. While GRDP affected positively only right before the event, and the employment rate was not significantly affected by the event. The real estate price was increased from the announced time of hosting to the event held, but later decreased. This study suggested the comprehensive method for analyzing the effect of Mega-event and there was a cyclical causality among the result variables.

  • 수리시설개보수사업을 통해 농업용저수지를 보강하는 방법은 여수로의 통수능력을 증대시키기 위해 물넘이 길이를 확장하는 방법과 예비방류가 가능하도록 부분게이트를 설치하여 홍수조절효과를 기대하는 일정량 방류방식을 혼합한 형태로 설계를 하고 있다. 이는 현실적으로 투자가 가능한 예산범위 안에서 최소한의 피해를 줄이기 위해 적절히 적용가능한 방법이다. 하지만 아직까지 게이트의 설치 위치나 형식에 관한 고찰이 없었으며 홍수배제능력검토 방법 또한 일관성 있게 이루어지고 있지 않다. 그리고 유지관리측면에서도 현재 많은 문제점이 나타나고 있다. 비상게이트 설치에 따라 홍수기시 하류지역의 침수피해가 발생하며 유지관리비용도 과거에 비해 상당히 늘어나고 있다. 하지만 최근 국내 기상여건하에서 저수지제체 안전도를 높이기 위해서는 농업용저수지에도 여수로 게이트가 반드시 필요한 실정이다. 농업용저수지의 설계홍수량 증가에 따라 홍수량 배제시설의 규모도 커져야 하나 지형적인 여건상 물넘이의 확장이 불가능한 지역도 많으며 물넘이 시설의 확장으로 인해 저수지 하류지역의 피해에 따른 민원도 제기됨에 따라 농업용저수지 여수로 게이트의 합리적이고 표준화된 모델이 제시되어야 할 것으로 판단된다.

  • The aim of this study is to forcast the economic impact of Yosu-Kwangyang harbour on the regional employment. Industries in relation to this harbor can be divided into three parts; related industries to harbor(RI), direct dependent industries on harbor(DDI), indirect dependent industries(IDI). Research regions are 4 cities (Yosu, Yochun, Soonchun, Dongkwangyang) and 3 counties (Yochun, Seungju, Kwangyang).In the aspect of employment, the Yosu-Kwangyang harbor produced a good effect in these regions. In 1995, the rates of the dependence on harbor were showed up RI 1.63%, DBI 3.33%, IDI 15.99%, TOTAL 19.95%. In the Suture, the rates may be showed up various results as; in TOTAL rates, 33.59% in 2000, 44.95% in 2005, 48.03% in 2010, 49.82% in 2015.

  • 벼의 생육과 수량에는 토양과 생물환경 못지 않게 기상환경도 중요하다. 기상환경 중에서도 기온과 일조시수의 영향은 매우 커서 이에 대한 연구가 많이 이루어 졌다. 따라서 본 시험에서는 여수지역에서의 10년간 기상조건과 벼의 수량성을 비교하였던바 생육 초기의 영양생장기에 비하여 생육후기의 생식 생장기에서의 높은 고온과 많은 일조시간(일사량)은 증수되는 경향이 었다.
