        This study explored the usefulness and implications of the Bayesian hyperparameter optimization in developing species distribution models (SDMs). A variety of machine learning (ML) algorithms, namely, support vector machine (SVM), random forest (RF), boosted regression tree (BRT), XGBoost (XGB), and Multilayer perceptron (MLP) were used for predicting the occurrence of four benthic macroinvertebrate species. The Bayesian optimization method successfully tuned model hyperparameters, with all ML models resulting an area under the curve (AUC) > 0.7. Also, hyperparameter search ranges that generally clustered around the optimal values suggest the efficiency of the Bayesian optimization in finding optimal sets of hyperparameters. Tree based ensemble algorithms (BRT, RF, and XGB) tended to show higher performances than SVM and MLP. Important hyperparameters and optimal values differed by species and ML model, indicating the necessity of hyperparameter tuning for improving individual model performances. The optimization results demonstrate that for all macroinvertebrate species SVM and RF required fewer numbers of trials until obtaining optimal hyperparameter sets, leading to reduced computational cost compared to other ML algorithms. The results of this study suggest that the Bayesian optimization is an efficient method for hyperparameter optimization of machine learning algorithms.

        After being subjected to different cooking methods, small black beans (Rhynchosia nulubilis) were investigated in order to assess the effects of the retained bioactive compounds. Using uncooked, pan broiled, boiled, steamed, and pressure cooked beans, the inhibitory effects of MCF-7 cell migration were evaluated at protein concentrations of 40, 160, and 640 μm/mL, using the Boyden's chamber assay. All protein concentrations (40, 160, and 640 μm/mL) of pan broiled beans showed significant reduction (59.83, 32.48, and 21.37%, respectively) in the rate of cell migration to the lower chambers (p-value less than 0.001). Estimated cell migration rates correlated to the exponential decay between experimentally measured cell migration rates and converted samples. The range of estimated cell migration rate for each 100 mg/mL of cooked sample was as follows: pan broiled (21.16%), boiled (22.48%), steamed (22.48%), pressure cooked (29.52%), and uncooked (35.03%) beans. Our study indicated that selective modifications of cooking methods for small black beans, such as pan broiling, ameliorated the inhibitory effects of MCF-7 cell migration. This suggests that optimized cooking methods increase the nutritional contents of the cooked food.

        국내 농업은 각종 FTA, 고령화, 벼농사 가격하락 등 다양 한 위기에 처해있다. 이러한 어려움을 극복하기 위한 방안 으로 시설원예를 통한 농산물 생산이 주목받아 2010년 이 후 농업에서 원예산업이 약 40% 정도를 차지하고 있다. 이 러한 원예산업은 국내 농업분야에서 국제 경쟁력 제고를 위 해 시설원예의 규모화, 단지화를 추진하고 있으며, 새만금을 비롯한 간척지 사업에 적용을 고려하고 있는 실정이다. 생태 적 서비스의 제공은 인간사회에 필수적으로 필요요소 이지 만, 농업경관에서 시설원예단지 조성은 불투수면적 확장과 생물서식처 손실로 인해 생태계서비스 기능저하의 원인이 될 수 있다고 평가된다. 하지만 최근의 시설원예단지 개발은 대규모, 에너지 고효율에 초점이 이루어져 있어 농업경관 안에서의 생태계서비스에 대한 고려사항은 전무한 실정이다. 이러한 관점에서 시설원예단지 조성 시 고려해야할 생태계서 비스 기능 분석 결과 수자원함양(Groundwater recharge), 지 표수저장(Water storage), 양서파충류 서식처(Amphibian & Reptile habitat), 수서곤충 서식처(Aquatic insect habitat), 홍수조절(Flood control), 수질정화(Water purification), 조 류 서식처(Avian habitat), 경관창출(Creating landscape), 식생다양성(Vegetation diversity), 체험/생태교육(Experience, Education), 생물학적 방재(Biological control), 어류 서식 처(Fishery habitat), 기후순화(Climate regulation), 포유류 서식처(Mammal habitat), 대기정화(Air quality regulation), 유전적 다양성 보존(Mainenance of genetic diversity), 휴식 제공(Rest area) 순으로 분석된 바 있다. 그 중 경관창출 기 능은 논, 밭, 산림, 가옥 등 농업경관이 가지는 본래의 특유 경관으로 쾌적하고, 자연적이며, 밝고, 좋고, 친근감 있고 아름다운 경관으로 평가되고 있다. 하지만 국내 시설원예단 지 운영의 경우 경관에 대한 고려 없이 적재물, 폐비닐, 연료 통 등이 질서 없이 방치되고 기존 농업경관과 다소 조화롭 지 않은 것이 현실이다. 따라서 본 연구에서는 시설원예단지의 생태계서비스 기 능 중 경관창출기능을 제고하기 위한 방안으로 국내외 사례 에 대한 경관이미지 평가를 실시하고자 하였다. 이러한 연 구를 통해 농촌지역의 경관을 아름답게 유지, 개선하고 앞 으로 조성 될 대규모 시설원예단지 조성 시 경관창출이 가 능 할 수 있도록 활용하고자 한다. 연구대상지는 국내 온실 분포현황을 고려해 대표적 시설 원예단지인 비닐하우스(Vinyl Greenhouse : v), 유리온실 (Glass Greenhouse : g)로 구분하였다. 비닐하우스단지는 충남 부여군 세도면에 위치한 토마토 재배단지를 선정하고 비교를 위해 일본(Japan : J) 후쿠오카현 원예단지 경관을 선정하였다. 유리온실은 국내(Korea, K) 최대 규모로 알려 진 구미 옥성리 화훼단지 경관을 선정하고 네델란드 (Nederland : N) Berkel en Rodenrijs 지역 유리온실 경관과 비교하였다. 경관 평가는 형용사를 활용한 어의구별척으로 실시하였다. 형용사 선정은 농업, 농촌, 경관과 관련된 대표 적인 선행연구인 KRCC(2007), Jo et al.(2012), Son et al.(2011), Kim et al.(2009), Yoo et al.(2000), Kim & Kim(2010), Joo & Lee(2012), Yoo et al.(2009), Lee(2005), Sin(2006) 등 총 10개 분석하여 사용빈도가 높고 본 연구에 적합하다고 판단되는 것으로 선정하였다. 사진 슬라이드는 연구대상 지역별로 3구역을 선정하였다. 평가는 2015년 10 월에 단국대학교 조경학과 3학년 51명, 경상대학교 생물산 업기계공학과 3학년 50명을 대상으로 실시하여 총 101명의 답변을 연구에 활용하였다. 평가결과 국내 비닐하우스 경관(Kv)은 인공적이고(-0.75), 갑갑하며(-0.50), 생명없어(-0.23) 보이는 등 대체로 부정적 인 결과로 분석 된 반면, 일본 비닐하우스 경관(Jv)은 조용하 고(1.38), 넓으며(1.24), 정돈되고(1.33), 쾌적한(1.31) 등 모 든 형용사에서 긍정의 이미지 평가 결과로 분석되었다. 구미 옥성리 유리온실 경관(Kg)은 넓고(0.66), 정돈되고 (0.57), 평화로운(0.49) 등의 긍정의 이미지로 분석되어 국 내 비닐하우스 경관 보다는 평가 결과가 높았지만 인공적이 고(-0.16), 생명없는(-0.10), 정감없는(-0.20) 등 부정의 이미 지를 포함하고 있어 개선이 필요 할 것으로 판단된다. 이에 반해 네델란드 유리온실 경관(Ng)의 경우 네가지 유형 중 가장 이미지 평가결과가 높게 평가되었다. 본 연구를 통해 시설원예 단지의 경관을 위해 비닐하우스 유형은 일본을 유리온실 유형은 네델란드 형태로 개선을 추진 할 수 있다고 판단된다. 더불어 비닐하우스 경관 보다 는 유리온실 경관이 높게 분석되었으므로 비닐하우스 경관 에 대한 개선이 우선 되어야 할 것으로 보인다. 추가분석을 통해 전봇대, 기름통 등의 가변요소, 녹시율, 도로폭 등을 분석하여 시설원예단지 경관 개선 및 조성모델을 제시하고 자 한다.

        A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. To this end, we presented objective and standardized criteria to predict and judge the effects of development projects on landscapes before project implementation. During the implementation of the development project, the influence of the visual landscape becomes accumulated in the construction progress stage. There is a need to identify the main viewpoints and to examine the continuous changes in the landscape-influencing factors, owing to the remarkable influences on the landscape, such as the change in the topography and the change caused by the artificial structure. During the stage of managing the influence on the visual landscape after the completion of the project, the influence on landscape should be monitored by measuring the change in the continuous landscape-influencing factors and determining the extent to which the actual reduction plan has been implemented. These processes should be performed continuously to maintain the quality of the visual landscape. The change in the landscape caused by the development project is shown to cause relatively greater visual damage than other factors composing the landscape owing to the influence of the artificial factors including the structure or the building. This shows that not only detailed examination of the visual impact before the development project but also continuous management is required during and after the development project. For this purpose, we derived eight landscape-influencing factors including form/shape, line, color, texture, scale/volume, height, skyline, and landscape control point. The proposed considering to be of high utilization in that it has a clear target of the landscape influencing factors.

        While cities became bigger and bigger since 1990s, many indiscretely high buildings started to be built in the mountain areas inside a city and in the rural areas in the suburb of each city. To regulate such indiscrete developments, the government prepared for some relevant legal and institutional criteria by having enacted the “Landscape Act” and established a strong management means in the legal and institutional aspects by having introduced the natural landscape deliberation system and the landscape deliberation one into the “Natural Environment Conservation Act.” However, since some uniform levels of absolute height and no. of stories are suggested legally and institutionally, it is hard to consider the effects of a real building structure onto the relevant landscape. Accordingly, this thesis is intended to grasp the contrast of the landscape elements in the allowable height section, which is presented through landscape sensitivity. As the results from the visual contrast rating on a small apartment complex located in Dangjin and a large scale of apartment complex in Seosan as the apartment complexes surrounded with natural landscapes that were selected as the subjects of this study, the following conclusion can be finalized. First, there were deducted some factors, that is, forms, lines, colors, textures and sizes as the ones with which can measure and evaluate the contrasting properties when a structure gets into a natural landscape. Second, in case of a small scale of apartment complex (in the foreground) compared to a large one (in the foreground), it was found that the contrasting properties were bigger. In addition, it was also found that the contrasting property of the landscape factor of the foreground compared to that of the middle one becomes bigger depending on a distance. Third, as the results from an evaluation on the contrasting properties of the landscape factor depending on the changes of each floor of a structure, it was found that the factors, that is, forms, lines, colors, textures and sizes are very significant. Among those factors, the factors, forms and lines in a small scale of apartment complex (in the foreground) showed each log regression. But in all of the other cases, they showed each line regression. Fourth, as the results from examining the regression coefficients of the landscape factor, the coefficients of the shapes and lines have similar coefficients and the colors and the textures have similar ones, too. In case of the sizes of apartment complexes, the colors and the textures of a large apartment complex (in the foreground) have similar coefficients, in case of that in the middle ground, the shapes and lines have similar coefficients. Fifth, as the results from estimating the contrasting properties of the landscape factor on the floors within the allowed scope of the landscape sensitivity, it was found that the contrasting property was 3.5 to 4.9 in case of a small scale of apartment complex (in the foreground), but 2.5to 3.7 in case of a small scale of one. In case of a large scale of apartment complex, the value was 3.5 to 5.3, but in case of a large one in the middle ground was 2.9 to 4.9. Sixth, it was comprehended that the contrasting properties of the landscape factor become different depending on each size of apartment complex and the distance of a view point. In this study, it is intended to find the meaning from the aspect that the results can be used as the baseline data for comprehending a proper range of heights of structures objectively during a natural landscape deliberation or a landscape deliberation.

        As high-rise buildings came in, the landscape of rural areas and natural landscapes often got damaged. Therefore, this study aims to prevent this, grasp the extent of the influence of the surrounding landscape, to grasp the range of height that can be permitted and present the direction of landscape management of agriculture and natural landscape. This study tried to grasp the range of height by using price sensitivity analysis method for two apartment and apartment complex which entered DangJin city and SeoSan city. First, in the case of a two apartment, the range of the height allowable section was from the 6th floor to the 11th floor in close range view, and it was a section from the 7th floor to the 12th floor in medium range view. In the case of the apartment complex, the range of the height allowable range was from the 10th floor to the 17th floor in close range view, the 9th floor to the 16th floor in medium range view. The stress index was found to be positive in a two apartment in close range view, and in the apartment complex case. therefore it was better to set it to a lower in the Range of Acceptable Height(RAH). Second, it showed no difference in the sensitivity of landscape to gender. Thirdly, the results of the landscape sensitivity analysis of major and non-major showed the difference in the medium range view picture of the apartment complex. Majors are lower than the point of minimum height(PMinH) than non-Majors. In the case of major, the stress index was 1.4. it turned out that it was better to make a decision closer to point of minimum height (PMinH). In the case of non-major, the stress index was –1.3. it was also able to accept decision close to the point of maximum height (PMaxH). Since the results of the above research gave changes only in the variable of the height of the landscape, we can not grasp the point of interaction with other variables, and future research is considered necessary.

        This study aimed to identify the aquatic and riparian factors associated with the presence/absence of the Eurasian otter in the Nakdong river basin, where the species is relatively more abundant than other otter species. Environmental factors and presence records were collected. Geographical Information System technology and chi-square test were used to compare environmental gradients in aquatic and riparian factors between presence and absence sites. Aquatic habitat attributes were evaluated with natural riverside sandbars and channel crossing artificial structures, the ratio of channel width to alluvial plain width, riverbed substrate, and flow diversity. Riverbank characteristics, bank materials, man-made embankment types, and land use/land cover of inland and riverside areas were selected as riparian habitat attributes. Compared to the aquatic attributes, riparian attributes were highly significant when assessing otter presence and absence sites, suggesting that conservation of suitable riparian areas to provide maternity and resting areas for otter species is essential in the Nakdong river basin. None of the aquatic attributes examined were statistically significant when evaluating otter presence or absence. These results indicate that the presence of suitable riparian area for resting and reproduction habitats is more critical to the presence of Eurasian otter than food availability in aquatic areas. To inform implementation of effective conservation action

        Humans are provided with a wide range of public benefits from ecosystems and agricultural ecosystems. But the establishment of the horticulture complex is a space that hampers the public ecosystem. Therefore, we have evaluated the creating landscape function of the horticulture complex and found improvement. A total of 20 landscape slides were used for the study. Korea-paddy field, Korea-vinyl greenhouse, Korea-glass greenhouse, Japan-vinyl greenhouse and Netherlands-glass greenhouse were selected as 4 slides. The evaluation used the AHP method and 10 adjectives Likert which compares 20 landscape slides. Four Korea-paddy fields were rated highly positive images. All 10 adjectives can be selected as representative images of production scenes. In most adjectives, four scenes of KVG1, KVG2, KVG3 and KVG4, which are the Korea-greenhouse scenes, were evaluated as negative images. Netherlands and Korea-glass greenhouse scenes and Japan-vinyl greenhouse scenes were generally positive images. In conclusion, it is confirmed that glass greenhouse scenery is higher than vinyl greenhouse scenery. And Japan and Netherlands scenery are higher and better than Korea. Therefore, JVG1 in Japan and NGG3 in the Netherlands were proposed to be set as landscape improvement targets.

        With increasing public concern for environmentally friendly agriculture, ecological aspect of landscape management is of growing importance. AHP (Analytical Hierarchy Process) analysis were conducted based on the delphi survey of 31 experts to evaluate the relative importance and the preference of landscape elements. Landscape components of organic farmland were classified into 2 landscape fields, 5 landscape types, 14 landscape units, and 37 landscape elements. Overall relevance score for the proposed landscape components were about 5.5 on the seven point scale. While the relative importance weight of cropland landscape field was 0.71, the weight of intra-structure landscape field was 0.29. Among the cropland landscape, relatively higher weight was assigned to farming system (0.47) and margins (0.31), as compared with hydrological system (0.22). In the farming system, crop (0.40) and farm land (0.39) were the most important landscape units. In the margins, higher weight was given to Buffer zone (0.44) and Trees (0.42). Biological habitat (0.43) ranked the highest score in the hydrological system. Preferable landscape elements were glass house, companion plants, rice paddy field, diverse crop species, small pond, and small river, which are representing ecological advantage of organic farming systems. This result indicated that the landscape elements identified in the study would be suitable to evaluate ecological aspect of rural landscape in organic farmland.

        Biomass resources might be recognized as a promising way to alter fossil fuels, such as petroleum oil, natural gas and coal and to prevent the emission of greenhouse gases which will bring about global warming. Therefore many countries have tried to identify and secure available biomass resources. In this study, the energy potential of Korean biomass resources, such as agricultural biomass wastes, municipal solid wastes, and livestock wastes, was analyzed and calculated by using various data. The available energy potential in 5 major cities in Korea was over 3.5 M TOE. Especially the municipal solid wastes was over 1.5 M TOE, so the conversion of municipal solid wastes might be easily adopted.
