우리나라 서 남해안에 위치한 59개 갯벌의 다모류 출현 양상을 바탕으로 갯벌의 생태등급을 평가하였다. 갯벌의 생태등급 평가는 다모류의 분포밀도, 다양성, 풍부성, 자원적 가치, 종 위험도 등의 생물학적인 자료와 해안선의 자연성, 훼손 가능성, 지형경관 등의 인문지리학적인 면을 평가기준으로 하였다. 조사지역에서 출현한 다모류는 총 14목 37과 181종이었으며, 각 조사지역의 생태등급은 다음과 같다. I 등급 4개 지역(충남 학암포, 전남 우이도와 거문도, 경남 비진도와 매물도), II 등급 30개 지역, III 등급 19개 지역, IV 등급 4개 지역이었다. 이번 조사 결과 생태등급 기준에 대한 보다 면밀한 검토가 필요할 것으로 생각되며, 선정된 각 해역의 생태등급에 따른 정기적인 생물 조사 및 생태계 위협요인의 제거와 같은 실질적인 관리 방안을 마련하여야 할 것으로 판단된다. 특히 생물상 및 자연성이 높은 생태등급 지역의 경우 보다 적극적인 보전 노력이 요구된다.

The main aim of this research is centered on the relation between nature and humans, and is to study the ecological characteristics appearing both in Landscape Architecture, one of the currents of ecological architecture as the architectural solution on the relation between humans and nature, and in our traditional architecture. Through this study, we were able to see that our traditional architecture was influenced by our ancestor's view of nature, and that the foremost feature of our ancestor's view of nature on our traditional architecture is not conflicting with nature, but, instead it is complying with it through seeking harmony with nature. Also we could see that our ancestor's view of nature is similar to Landscape Architecture having come to the fore toward the tendency of modern ecological paradigm in that it is the representation seeking the organic view of nature pursuing the oneness among artificial structure, humans, and nature. That is, we could figure out that various ecological features appearing in modem Landscape Architecture had been represented for a long long time, in a natural fashion, In the manner of space makeup in our traditional architecture. This is the characteristic of our ecological thinking system understanding nature and humans at the same context, and it has come down not only to our everyday living but to the manner of architectural solutions as well. Through this research, we could reconsider the modern value of ecological architecture inherent in our traditional architecture.

It has been a common misconception that landscape architecture is a gardening, landscape gardening or planting. However, landscape architecture is entirely different from gardening, landscape gardening and planting when it comes to professional category. Landscape architecture is a interdisciplinary science to improve a quality of citizen's life through analysing social culture, psychological configuration, aesthetic characteristic and integrating them in human society. Today's landscape architecture is a interdisciplinary technology including ecological and artistic value to create most of outdoor space used by human through preserving nature and enhancing the environment. The field has been changed constantly in the flow of the period and social development as providing green network system, recreation area, ecological environment in the city.

This study was conducted to investigate the effects of Momordica charantia saponin (MCS) on ruminal fermentation of maize stover and abundance of selected microbial populations in vitro. Five levels of MCS supplements (0, 0.01, 0.06, 0.30, 0.60 mg/mL) were tested. The pH, $NH_3-N$, and volatile fatty acid were measured at 6, 24, 48 h of in vitro mixed incubation fluids, whilst the selected microbial populations were determined at 6 and 24 h. The high dose of MCS increased the initial fractional rate of degradation at t-value = 0 ($FRD_0$) and the fractional rate of gas production (k), but decreased the theoretical maximum of gas production ($V_F$) and the half-life ($t_{0.5}$) compared with the control. The $NH_3-N$ concentration reached the lowest concentration with 0.01 mg MCS/mL at 6 h. The MSC inclusion increased (p<0.001) the molar proportion of butyrate, isovalerate at 24 h and 48 h, and the molar proportion of acetate at 24 h, but then decreased (p<0.05) them at 48 h. The molar proportion of valerate was increased (p<0.05) at 24 h. The acetate to propionate ratio (A/P; linear, p<0.01) was increased at 24 h, but reached the least value at the level of 0.30 mg/mL MCS. The MCS inclusion decreased (p<0.05) the molar proportion of propionate at 24 h and then increased it at 48 h. The concentration of total volatile fatty acid was decreased (p<0.001) at 24 h, but reached the greatest concentration at the level of 0.01 mg/mL and the least concentration at the level of 0.60 mg/mL. The relative abundance of Ruminococcus albus was increased at 6 h and 24 h, and the relative abundance of Fibrobacter succinogenes was the lowest (p<0.05) at 0.60 mg/mL at 6 h and 24 h. The relative abundance of Butyrivibrio fibrisolvens and fungus reached the greatest value (p<0.05) at low doses of MCS inclusion and the least value (p<0.05) at 0.60 mg/mL at 24 h. The present results demonstrates that a high level of MCS quickly inhibits in vitro fermentation of maize stover, while MCS at low doses has the ability to modulate the ruminal fermentation pattern by regulating the number of functional rumen microbes including cellulolytic bacteria and fungi populations, and may have potential as a feed additive applied in the diets of ruminants.

A new evaluation technique, i.e. multicriterion matrix technique, on the vegetation assessment was proposed and compared with several techniques having been previously used in the environmental impact assessment. Four criterias and 10 subcriterias were selected for two evaluation indices such as vegetation naturalness value and vegetation class. These criterias were characterized by syntaxonomical informations of hemeroby concept and potential vegetation, hierarchical system between criterias, and ordinal scale of vegetation naturalness valuse. Vegetation naturalness values were classified into 11 ordinal levels and condensed to five vegetation classes for facilitating practical use. In the example study two sites were compared by using two indices. This technique could have useful applications for ssessment of regional vegetation. A vegetation map of naturalness described by combination of two indices was proposed in order to illustrate regional vegetation naturalness.

The ecological behaviour and forage value of natural grassland communities and the similarity between plant communities near Wit~enhausen in middle part of Gennany were investigated from June to August. 1993. The total number of plant communities at different place surveyed during the study period was twelve. The ecological behaviour and forage value of the natural grassland communities except mesobromion (half dry grassland community) were relatively good for roughage production. The correlation coefficients between plant eornmunilies were greatly affected by botanical composition. The clustering analysis showed that the communities of relatively similar botanical composition were grouped closely, and the other communities were clustered to the same group although the degree of similarity between communities was low.

Purpose: As the number of vegetarians continues to rise in tandem with the development of consumer culture, a novel economic trend named 'Vegenomics' has surfaced. In addition, as interest in social and environmental sustainability such as health, environment, and animal welfare grows due to the COVID-19 pandemic, the alternative protein food market is expanding, focusing on plant-based alternative meat. Research design, data, and methodology: Therefore, this study aims to investigate the impact of the consumption value of alternative protein products on self-efficacy and purchase intention. This study collected a total of 187 questionnaires by conducting an online survey from May 1 to July 10, 2023, to verify the research model and hypothesis. The collected data were subjected to exploratory factor analysis, confirmatory factor analysis, and discriminant validity analysis using SPSS 20.0 and AMOS 20.0 programs for structural equation modeling. Results: The results of analyzing consumers' self-efficacy and purchase intention regarding the functional value, health-oriented value, ethical value, and ecological value of alternative protein products are as follows. First, among the consumption values of alternative protein products, ecological value was found to have a significant positive (+) effect on self-efficacy. Second, consumers' self-efficacy for alternative protein products was found to have a significant positive (+) effect on purchase intention. Conclusion: This study is anticipated to provide valuable insights for the formulation of effective marketing strategies for alternative protein products and the development of products that align with consumer needs.

본 연구는 1) 수변공원에 서식하는 생물상 및 생태현황 조사를 통해 수변공원의 생태적 가치를 평가하고, 2) 조사결과를 기반으로 한 생태교육 및 홍보를 통해 수변공원에 대한 이용 및 비이용객의 생태적 인식 변화를 분석하였다. 수변공원 92개소를 대상으로 생물상 조사를 수행한 결과, 수변공원에서는 멸종위기종 9종(벌매, 붉은배새매, 새호리기, 흰목물 떼새, 삵, 수달, 맹꽁이, 수염풍뎅이, 은줄팔랑나비)을 포함하여 다양한 생물의 서식이 확인되었다. 수변공원은 비록 인간의 이용을 위한 친수적인 성향으로 조성되었지만, 일부 자연성이 높은 지역은 생물서식처로 가치가 높은 것으로 평가되었다. 수변공원에 대한 인식 정도를 평가하기 위해, 금강유역 내 5개 지역(대전, 세종, 청주, 공주, 부여)에서 이용객 현황을 조사하고, 생태교육 및 홍보를 실시하였다. 총 200명을 대상으로 이용객 현황을 조사한 결과, 생태공원에 대한 이용객이 비이용객보다 더 많은 비율을 차지하였으며, 연령별로는 40대가 가장 높은 이용률을 나타냈다. 대전이나 청주 등의 지역에서 수변공원의 이용 빈도는 다른 지역보다 낮은 것으로 조사되었다. 대전이나 청주는 도심구간으로 수변공원 외에도 체육시설이나 카페 등의 여가시설이 상대적으로 많아 수변공원에 대한 의존도가 타 지역보다 낮은 것으로 사료된다. 이용객은 이용대상 수변공원과 실제 거주지간 거리가 가까울수록 이용 빈도가 증가하는 것으로 나타났다. 이는 이용객 대부분이 수변공원을 '생활체육공간'으로 인식하고 있기 때문에 도보가 가능한 거리가 아니면 활용 빈도가 낮은 것으로 보인다. 이러한 수변공원에 대한 인식은 생태교육 및 홍보 후 '보전'적인 측면으로 인식하는 비율이 증가하는 것으로 나타났다. 이러한 인식 변화는 이용객(80%)이 비이용객(38%)보다 더 높은 것으로 분석되었다. 이를 볼 때, 생태교육 및 홍보는 수변공원을 직접적으로 이용하여 특성이나 제원 등에 대한 이해도가 높은 이용객에게 더 효과적인 것으로 판단된다. 결과적으로, 1) 수변공원은 비록 친수적인 성향을 가지고 조성되었으나, 일부 지역은 멸종위기종의 서식하는 등 생물서식처로서 가치가 높은 것으로 평가되며, 2) 이를 볼 때, 수변공원에 대한 인식은 친수적인 성향만이 강조된 부분에서 보전적인 측면으로 강화가 필요할 것으로 사료된다. 이러한 인식 변화는 추후 수변공원에 대한 관리나 정비계획 수립 시 친수와 보전적인 측면이 공존하는 수변공원 조성에 기여할 수 있을 것으로 기대된다.

The effects of seedtime and maturity stage on nutritive value of five maize stover varieties, including conventional maize (Kexiangyu 11, CM), fodder maize (Huqing 1, FM), high oil maize (Gaoyou 115, HOM), sweet maize (Kexiangtianyu 1, SM) and waxy maize (Kexiangluoyu 1, WM), were examined based on chemical composition, in vitro gas production and in situ incubation techniques. Maize stover was sampled at d 17 and d 30 after tasseling, and designated as maturity stage 1 and stage 2, respectively. The average dry matter (DM) organic matter (OM), crude protein (CP) and fiber contents were the greatest for HOM, SM and FM, respectively. CM had the highest in vitro organic matter disappearance (IVOMD) and volatile fatty acid (VFA) concentration. The highest ammonia nitrogen ($NH_3$-N) concentration in the incubation solution, and effective degradability of DM ($ED_{DM}$) and neutral detergent fiber ($ED_{NDF}$) were observed in SM. Advanced maturity stage increased (p<0.05) DM content, $ED_{DM}$ and $ED_{NDF}$, but decreased (p<0.05) OM and CP contents, and decreased (p<0.05) b and a+b values, IVOMD and molar proportion of valerate in the incubation solution for maize stover. Maize sown in summer had greater (p<0.05) OM content, but lower DM, CP, neutral detergent fiber (NDF) and acid detergent fiber (ADF) content compared with maize sown in spring. Maize sown in summer had greater (p<0.001) IVOMD, $NH_3$-N concentration in the incubation solution and $ED_{NDF}$, but lower (p<0.01) ratio of acetate to propionate compared to maize sown in spring. The interaction effect of variety${\times}$seedtime was observed running through almost all chemical composition, in vitro gas production parameters and in situ DM and NDF degradability. The overall results suggested that SM had the highest nutrient quality, and also indicated the possibility of selecting maize variety and seedtime for the utilization of maize stover in ruminants.
