한국은 삼면이 바다로 되어 있어 염습지와 이에 인접한 해안사구가 발달되어 있다. 본 연구는 한국 서·남해안의 염습지와 사구에서 나타나는 염생식물의 군집과 식물상의 특성을 48개 지소의 571 식분에서 조사하고, 분석하여 연안 생태계의 특성을 밝히고자 시도하였다. 그 결과, 염습지에 분포하는 식물군락은 39개이었으며, 갈대군락의 분포면적이 가장 넓었고, 버들명아주군락이 가장좁았다. 나문재군락이 해안선으로부터 가장 근접하여 분포하였고, 해홍나물군락이 해양쪽으로 가장 멀리까지 분포하였다. 해안사구에 분포하는 식물군락은 29개이었으며, 갯그령군락의 분포면적이 가장 넓었고, 수송나물군락이 가장좁았고, 갯메꽃군락이 해안선으로부터 가장 근접하여 분포하였고, 해당화군락이 내륙쪽으로 가장 멀리까지 분포하였다. 염습지의 식물상은 6과 14속 17종 1변종 18분류군 이였으며(식물구계학적 점수; 16점), 해안사구는 11과 18속20종 1변종 21분류군(식물구계학적 점수; 34점)으로 해안사구가 염습지 보다 약간 높게 나타났다. 이러한 결과는 한국 서남해의 연안에서는 해안사구가 염습지보다 해수의 영향을 간접적으로 받기 때문에 염도에 약한 식물도 생육할수 있기 때문으로 해석된다. Korea is surrounded by the sea on three sides, salt marshes and coastal sand dunes adjacent to them are developed. This study attempted to reveal the characteristics of the coastal ecosystem by investigating and analyzing the characteristics of plant communities and flora of 571stands of 48 sites in the salt marshes and coastal sand dunes on the western and southern coasts of Korea..As a result, in the salt marshes, 39 vegetation units appeared, with Phragmites australis community having the widest area and Chenopodium virgatum community having the narrowest area. Suaeda glauca community was distributed closest to the coastline, while Suaeda maritima community extended the farthest seaward. In the coastal sand dunes, 29 vegetation units were distributed with Elymus mollis community having the widest area and Salsola komarovii community having the narrowest area. Calystegia soldanella community was showed closest to the coastline, while Rosa rugosa community extended the farthest landward. The flora of the salt marshes consisted of 6 families, 14 genera, 17 species, 1 variant, and 18 taxa (floristic regional indicator score; 16) and the coastal sand dunes consisted of 11 families, 18 genera, 20 species, 1 variant, and 21 taxa (floristic regional indicator score; 34) appeared slightly higher than that of salt marshes. This result is interpreted that halophyte that are sensitive to salinity can grow on the coast of the west-south coast of Korea because coastal sand dunes are more indirectly affected by sea than salt marshes.

Objectives: Many studies have investigated the electric specificity of meridian and acupoint. However, the definition about the real substance of ``Ki(Qi)`` that flows in the meridian has not been established yet. The authors hypothesized that the ``Ki(Qi)`` may be the very ``bioelectricity`` of western medicine, from two common features that they are not visible with naked eyes and that they function in the living body only. Methods: 20 healthy adults participated in this study. Heart rate was measured before and after exercise. Acupuncture was performed at PC6 immediately after exercise with counter balance in the first experiment. In the second experiment, acupuncture group was further divided to the three groups, i.e. glove acupuncture group, manual acupuncture group, and NaCl acupuncture group. In the glove group, acupuncturist put on the two folds of latex gloves to block bioelectric currents between the acupuncturist and subject. In the NaCl group, acupuncturist had his fingertips wet with NaCl solution. Results : Exercise increased Heart Rate and acupuncture at PC6 inhibited this increase. In the second experiment, the significant difference compared to the comtrol group was the most in NaCl acupuncture and the least in Glove acupuncture. However, there was no significant difference between three groups. Conclusions : The results of this study seem to be deficient as a conclusive evidence for the hypothesis that the ``Ki(Qi)`` of Korean Medicine is the ``bioelectricity`` of western medicine.

Low carbon green growth of railway has been mentioned as an alternative plan due to severe environmental, traffic problems that are caused by overdevelopment of road transportation in Korea, therefore they are constructing new road, improving road and railway throughout the country. But railway station areas have caused traffic congestion and lack of facilities for customer despite of progression, because the development was focused on commercial part and was poorly organized. Also it is said that they need to diversify their business except for railway fare. This report will suggest right way with analyzing domestic and foreign research about development plan in railroad station areas that can enhance a quality of residents’ life and create a new growth base in the railway station areas.

기후변화조건에서 구상나무의 생태적 변화를 파악하기 위해 5년 동안 대조구(야외)와 RCP 4.5에 근접하게 온도 및CO2를 상승시킨 기후변화처리구에서 생육 및 생리적 반응을 분석하였다. 그 결과, 기후변화처리구에서 구상나무의년생별 가지 길이는 시간이 지날수록 증가하는 경향이 나타났다. 그리고 기후변화 조건은 구상나무 잎의 형태적 차이에는 큰 영향을 주지 않지만, 잎의 생물량에는 영향을 주어, 기후변화가 진행될수록 구상나무의 잎 생산성이 저하될것으로 예상되었다. 한편, 기후변화 조건에서 구상나무의 엽록소 함량은 기후변화처리구에서 높은 반면, 광합성률, 기공전도도, 증산율, 그리고 수분이용효율은 대조구가 더 높게 나타났다. 이는 온도와 CO2가 상승된 환경이 기공밀도증가에 영향을 줄 수 있으나, 광합성 반응에는 부정적 영향을 주는 것으로 예상된다. 향후 이를 확인하기 위해 각각의환경 처리에서 기공 밀도에 대한 추가적인 연구가 필요할 것으로 판단된다. 한편, 본 연구에서는 잎의 생물량 변화만관찰하였기 때문에 기후변화 조건 하에서 구상나무의 생물량 변화에 대한 추가적인 실증 연구가 고려되어야 할 것으로 사료된다. 결과적으로 장기간 상승된 온도와 CO2에서 구상나무의 환경 적응력은 약화될 것으로 판단된다. To assess the ecological changes of Korean fir (Abies koreana E. H. Wilson) under climate change conditions, growth and physiological responses were analyzed over a 5-year period in a control group (outdoors) and in a treatment group where the temperature and CO2 levels were elevated to closely resemble RCP 4.5 conditions. The results showed an increasing trend in annual branch length of A.koreana in the climate change treatment group over time. While climate change conditions did not significantly impact the morphological differences of A.koreana leaves, they did influence the biomass of the leaves, suggesting that as climate change progresses, the productivity of A.koreana leaves may decline. On the other hand, the chlorophyll content in A.koreana under climate change conditions was higher in the climate change treatment group, whereas the photosynthesis rate, transpiration rate, water use efficiency and stomatal conductance was higher in the control group. This suggests that an environment with elevated temperature and CO2 could influence an increase in stomatal density, but having a negative impact on photosynthetic reactions. Further research on stomatal density under each environmental treatment will be required to confirm this hypothesis. Additionally, as this study only observed changes in leaf biomass, further empirical research should be considered to understand the changes in biomass of A.koreana under climate change conditions. In conclusion, the environmental adaptability of A.koreana is expected to weaken in the long term under elevated temperatures and CO2.
