논 습지는 다양한 야생동물들의 주요 서식공간으로, 급 격한 개발 및 환경 변화로 인해 논에 서식하는 야생동물의 생물 다양성 보전에 위협이 되고 있다. 본 연구에서는 서해안에 위치한 논 습지를 이용하는 무미 양서류의 서식지 이용 특성을 규명하고자 2018년 3월부터 10월까지 당진시 대호 간척 농지에 서식하는 양서류의 풍부도와 서식 환경을 바탕으로 종들에게 영향을 끼친 주요 환경 요인을 파악하고, 서식지 이용 특성을 알아보았다. 연구 결과 조사 지역에서는 금개구리 (Pelophylax chosenicus)를 포함하여 참개구리 (P. nigromaculatus)와 청개구리 (Hyla japonica) 의 서식이 확인되었다. 3종에 영향을 끼치는 환경 요인으로 기온과 습도, 수심, 미소 서식지로 확인되었고, 청개구리는 수온에 영향을 받고 있었으며, 금개구리는 벼의 길이와 농법의 유형에 영향을 받고 있는 것으로 확인되었다. 3종은 모두 기온과 습도, 수심이 증가할수록 개체수가 증가 하는 경향을 보였고, 모내기한 필지를 가장 많이 이용했으 며, 번식 시기에는 미소 서식지 요인 중 필지를 가장 선호 하고 있어 조사지역이 3종의 주요 번식지로 이용되고 있는 것으로 판단된다. 금개구리는 관행에 비해 친환경 농지에서 더 많이 관찰되었는데, 이는 포식자와 제초작업으로 인한 주변 환경의 차이로 인한 원인으로 보인다. 본 연구를 통해 논에 서식하는 무미 양서류 3종이 선호하는 환경 요인은 종에 따라 다른 것을 확인할 수 있었다. 이 결과는 무미 양서류 보전에 중요한 자료를 제공할 것이다.

The purpose of this research is to study the evolution of the price of Burgundy wines and to try to identify the reasons for such an evolution. Land prices, rent prices and wine prices in Burgundy will be analysed over the last decades. In terms of results, the price of wine in Burgundy has been observed to rise drastically in recent years as well as the evolution of land and rent prices. A better comprehension of price variations could help wine companies manage their long term profitability, especially if land were considered as an investment (and therefore, part of the company). As a recommendation, marketing tools but also training should be used by craftsmen to build, promote and distribute strong brands in order to remain on the market but also to attract major agents and importers and be distributed worldwide.

This study is aimed comparative analysis for business performance of land-based ezo abalone (Haliotis discus hannai) seed farms by standardizing cost structures by region and farming size. The result of survey on average farming incomes by region showed that farming incomes in Haenam and Jindo regions were much higher than those in other regions. Followed by Wando region, incomes in other regions were analyzed to be relatively lower. It is shown that farming incomes became higher as farm size increased. Farming incomes per unit size which were modified from farming incomes by region were highest in Jindo region, followed by East sea region, Wando and Haenam regions. Incomes in Jeju and Yeosu regions were analyzed to be relatively lower. Results on farming incomes per unit size (m2) showed that both farming incomes and profits became higher as size increased. It implies that a scale effectiveness might exist in case of land-based abalone culture system. Impacts of major factors on farming profits and returns on investment in abalone seed aquaculture are summarized as follow. First, only if the survival rate increased by 10% with improvement of component ratio, variable effects became largest. In variable effects of other factors, a variation in Jindo region was largest and on the other hand, a variation in Yeosu region was shown to be smallest.

The dichotomous-choice contingent valuation method is applied to estimate the landscape value of Jeju Island's stonewall fencing farming land. A distribution-free approach, Turnbull empirical distribution model, is employed to solve negative willingness to pay and truncation problems. The data used are collected from the interviews with tourist about willingness-to-pay at the various donation amount levels of Jeju stonewall's landscape value. The evaluation result is shown that the average amount of willingness to pay for the Jeju stonewall fencing farming land is 3,001 won per meter with standard deviation of 511.0 won/m.

The purpose of this study is to develop the landscape resource assessment system(LRAS) to help evaluate the value of landscape resources(Jeju Island's Stonewall fencing farming land) for the introduction of direct payment system of the landscape preservation objectively and to applicate the model in the fields. Delphi survey on Jeju's stonewall experts shows that the order of priority among value evaluation elements on Jeju's stonewall is its harmony with surroundings(34%), the preservation of its original state(34%) and its density and scale(32%). Evaluation system development of landscape resources(Jeju's stonewall fencing filming land) and field observation survey utilizing it consists of the following five steps. Step 1 includes the first Delphi survey on Jeju's stonewall experts to decide its value evaluation elements and their priority. Step 2 is the second Delphi survey on Jeju's stonewall experts to grade pictures of landscape resources(Jeju's stonewall fencing farming land) on the basis of expert-proposed value evaluation standards. Step 3 consists of analysis work using the result of Delphi survey on experts. Step 4 is to select five grade standard pictures according to each of three grading elements of A, B, C belonging to each of the three standards. Then, it is necessary to make panels including five A-grade pictures, five B-grade pictures and five C-grade pictures according to each of the three elements of density, harmony, and original state preservation. Step 5 consists of field observation survey. According to the result of few experts' value evaluation of stonewall fencing farming land with the aid of NRAS developed in this research, the area of Pyeongdae-ri is ranked first, and then the area of Bukcheon-ri, Chocheon-up, the area of Gwakgi-ri, Ewol-up, the area of Shinum-ri, Ewol-up and the area of Yongsu-ri, hankyung-Myun are ranked in the order named. When those areas are graded, A Grade Areas includes the areas of Pyeongdae-ri, the area of Bukcheon-ri, the area of Gwakgi-ri, B Grade Areas consist of the area of Shinum-ri and the area of Yongsu-ri, and the areas of Onpyeong, wimi and youngrak belong to C Grade Area.
