  • 산림은 지구온난화의 주범이라 할 수 있는 이산화탄소를 광합성 작용을 통해 식생과 토양 등에 저장 할 수 있다. 또한, 산림에서 벌채된 나무는 부패되거나 연소되지 않는 한 장기적으로 이산화탄소를 저장할 수 있으며 벌채된 지역에서는 재조림을 통해 탄소흡수원을 확충할 수 있다. 산림은 증산작용을 통해 기온을 낮추는 등 미세기후 조절 역할로 지구기후시스템에 기여하고 있다. 이와 같은 이유로 지구 온난화를 줄이기 위해서 대기중에 방출된 온실가스의 흡수원으로서 산림이 필수적인 것으로 평가되어져 왔다. 이러한 측면에서 기후변화에 대한 지구 탄소 순환적응 프로그램을 확충하고 한국형 산림 모델로 발전 시키는 것은 매우 중요하다. 본 연구에서는 국외에서 개발한 여러 종류의 산림 부문 기후변화 영향 평가 모형을 비교 분석하여 우리나라 산림 생태 모형으로 적용할 수 있는지를 검토하였다. 또한, 모형별 입력 자료 확보 가능성을 기초로 구동 가능 모형을 선정하여 문제점을 파악한 후 대안을 도출하였다.

  • To select 10 representatives for the ecotourism networks around the areas bordering national rivers in Korea, the spatial ranges for ecotourism have been established, the ecotourism potential analyzed, and the ecotourism resources information collected by the Regional Environmental Offices and the Korea National Park Service has undergone reviews, amendments, supplements, and verification processes through familiarization tour previews, and the following main results have been derived. First, the spatial ranges of the eco-tourism networks have been set as the watershed areas that include areas around the four major rivers and the rivers. Second, the areas with high potential value for ecotourism were selected through the analysis of ecotourism potential. Since EGIS was used for the analysis, it was inevitable that insufficient amount of localized information was reflected, and the use of the results as reference for the potential would be feasible. Third, it was possible, by reviewing, amending and complementing the results of ecological resource information collected by the Regional Environmental Offices and the Korea National Park Service, to select 50 representative ecological resources around the national rivers. The selected resources were considered for the adjacency, attractiveness of ecological resources, and uniqueness of the national rivers, and they were derived by screening expert advice, official opinion, and geographical analysis information. Fourth, 10 representative ecotourism networks based on watershed areas were selected, and suitable themes were given based on the resource characteristics. Fifth, the appropriateness for ecotourism has been confirmed, with the familiarization tour previews and survey results, preservation of the future ecotourism resources, and the establishment of the foundation as the basis. In the future, the remaining 9 ecotourism networks would also need to undergo a verification process such as familiarization tours. It is deemed that, through future ecotourism contests, if the programs that select locally-pioneered tourism programs resulting from the capacities of local entities and residents, then it would be more effective in discovering resources that are more localized and of higher regional value.

  • Coastal sand dune area is the important ecosystem as an ecotone which located between coastal area and terrestrial area. Moreover, it is very complicate landscape that have geomorphological interaction between erosion and accumulation of sand. Therefore, it is necessary to understand the sand dune ecosystem in view point of landscape scale including background landscape affecting origin of sand dune. Landscape ecological approach in the complicate ecosystem already started in developed countries, and it is applied to land management and biodiversity conservation strategies even in national scale. In this paper, landscape ecological analysis using landscape pattern analysis was carried out on 7 study areas (Yellow Sea : Hakampo and Doksan, South Sea : Namyeol and Balpo, East Sea : Hosan, Hupo and Goraebul) in Korean coastal sand dune ecosystem. Landscape elements were composed by 9 elements in these study areas. Major background landscape elements was the forest land and agricultural field. Namyeol (S06) has larger patch landscape compare to other areas. In patch shape indices, Hupo (E10) shows more complicate patch shapes. The high landscape heterogeneity showed in the Doksan sand dune area and that of Hosan. It shows that these areas were composed by various patch types. However, using landscape indices have to use very carefully because several variables have influence to the result such as scale and spatial pattern of study areas. Although landscape analysis through landscape indices shows sometimes difficult to explain the ecosystem, landscape scale approach on ecosystem assessment still useful to interpret in ecological process in large range of habitat.

  • 우리나라의 대부분의 골프장은 법적, 경제적 이유로 건설부지가 계곡과 능선 또는 봉우리를 포함할 수밖에 없는 실정이다. 계곡과 능선은 생태계에 있어서 매우 중요한 부분을 차지하고 있으므로 이를 훼손하는 것은 생태환경의 변화에 큰 영향을 미치게 된다. 따라서 골프장 공사로 인해 발생하는 훼손을 최소화하고 기존의 계곡 또는 하천이 하던 생태적 기능을 수행할 수 있는 생태복원형 하천을 환경보상적 차원에서 설치하는 것이 매우 중요하다. 본 논문에서는 골프장 내의 하천을 생태하천으로 복원하기 위해 고려해야할 사항과 적합한 공법 및 사례를 통하여 골프장건설로 인한 환경영향을 최소화하고 자연환경과 조화를 통하여 최적의 골프장을 조성할 수 있도록 설계도면 실례를 들어 제안하였다.

  • This study aimed to suggest priority for developing emission factor (EF) and to develop the methodology of quantitative assessment of EF in the forestry sector. Based on the stock-difference method, 17 kinds of EFs (27 EFs based on forest types) were required to calculate the carbon emission in the forestry sector. Priority for developing EFs followed the standards, which is a development plan by the government agency, importance of carbon stock for greenhouse gas, and EFs by the species. Currently, the most urgent development of EFs was carbon fraction in biomass and carbon stock in dead wood. Meanwhile, the quantitative assessment of EF consisted of 7 categories (5 categories of compulsory and 2 categories of quality evaluation) and 12 verification factors. Category in compulsory verification consisted of administrative document, determination methodology of emission factors, emission characteristic, accuracy of measurement and analysis, and data representative. Category in quality evaluation consisted of data management and uncertainty estimates. Based on the importance of factors in the verification process, each factor was scored separately, however, the score needs to be coordinated by the government agency. These results would help build a reliable and accurate greenhouse gas inventory report of Korea.

  • 기후변화가 심화됨에 따라 식물계절연구의 중요도가 증가하고 있으며 자동영상촬영장치 (피노캠, Phenocam)을 활용한 연구방법이 급부상하고 있다. 본 연구에서는 국립생태원에서 운영하는 피노캠을 활용하여 국내 주요 생태계 유형에 대한 식물계절 변화의 경향을 확인하고 기후요인과의 상관관계를 분석했다. 식물계절의 변화 양상은 지역 및 수종별로 다르게 나타났다. 곰솔 및 소나무림은 전체 생장 기간이 증가하는 경향을 보이며 주로 겨울철 기온과 강수량과 양의 상관관계를 보였으나, 한라산 구상나무는 8월 강수량이 많을수록 생장종료일이 빨라졌으며 최근 발생하는 구상나무 고사 현상과의 연관성 분석이 추후 필요할 것으로 보인다. 분석 결과에서 더 나아가 데이터 수집 과정에서 발생할 수 있는 결측치 문제 등에 대한 해결책을 제시하였으며, 향후 연구 범위를 확장하고 다양한 생태계 유형을 반영하기 위해 피노캠 연구와 위성 관측을 결합하는 방안을 제안하였다.

  • The objectives of this study are to identify the environmental consumer behavior, to examine the degree of environmental consumer behavior of the junior high school students, and to investigate the educational system of a school which influence the consumer behavior. The data used in this study are 368 male and female students in 9th grade in Anyang City, Kyunggi-do province. Statistics used for data analysis are means, standard deviation, t-test, and Multiple Regression Analysis. The results of the research are summarized as follows : First of all, as a tendency of the environmental consumer behavior of junior high students, the primary factor to the environmental problems was media, and among those, TV and radio was the medium to environmental problems. This implies the fact that the time juveniles interact with mass media is significantly growing, which means that transmitting environmental problems by programs targeted to adolescences through mass media would be effective. Next, the disposal process showed the highest environmental consumer behavior, followed by the consuming and purchasing process. Education on the purchasing process will be necessary to encourage environmental consumer behavior. The route of obtaining environmental knowledge was basically from school and the level of the average environmental knowledge fumed out to be low. This shows the need to produce and distribute media education materials because educating the conclusion of actual experiments will be more effective than that of theoretical studies. The conformity showed general indifference on environmental consumer behavior and the environmental resources were normally collected seperated. Conformity is a cultural bond teenagers think important, therefore education available for students about the same age should be developed. Next, the value intention of the surveyed showed that the ecological intention was highest, followed by economic and convenience intentions. This means the morale of the junior high students to environmental consumer behavior is set sound. Females tended to act more environmentally, while males showed more intention to economic causes. Also, the students of the boys-only or girls-only schools showed higher environmentally sound behavior in disposal processes. Finally, the environmental consumer behavior was influenced most by environmental consumer behavior of the conformity group, followed by ecological morale, frequency of encountering environmental problems, gender, environmental knowledge, whether the school was boys-only or girls-only or not, economical morale, respectively. The largest factor affecting the consumer activity of the purchase, consumption, and disposal process was environmental consumer behavior of the conformity group, along with the ecological morale, and the frequency of encountering environmental problems. This implies that conformity group is a large factor to the juveniles and a plan to entice the environmental consumer behavior of conformity groups are necessary.

  • Objective: This paper discussed the characteristics of service design process by comparing with product design process. Background: Service design has different design outcomes, project participants, and design constraints than product design. Method: The comparison took two perspectives: one was shorter-term, design process of a service, and the other was longer-term, process of service development. Results: It was discussed that service design process is similar in overall, but has four differences. First, the role of design is required earlier and longer in the process, which means service designers need to participate from the begging of the project to service operation. Thus service designers are required to have holistic viewpoint of the project. Second, service design requires many design expertise thus collaboration needs to be well defined and managed throughout the process. Third, since service provider has limited resources, regulations, and market competition, some service features cannot be provided. Service designers are required to know both customers' needs and functional constraints. Last, service design is highly coupled with service operation. Designing and providing service happens at the same time and evolves over time. Conclusion: Consequently it was asserted that the role of designers in service design is essential for success. In specific, the role of service design architect, who manages design process and design outcomes, is a new and important role in service design project.

  • The word "soundscape" proposed by Canadian composer R. Murray Schafer is now became very popular. So various soundscape design based on soundscape idea are carried on worldwide for acoustic ecology. Also in Korea, several soundscape design were made for the public spaces such as river, park and bridge but, basic concept behind soundscape design was not reflected and studied sufficiently. In that sense, this study aims to arrange the concept of soundscape design process and to review the design proposals of Gwangju River. In this process, the reproduction concept of soundscape, natural sound, light with sound, cultural and historical sound and etc. were classified and the final design was proposed to recover the natural environment and harmonize the sound with surroundings as creative soundscape.

  • This Study, as a Eco-Friendly Design Process of Office for sustainable design, aims to develop a sustainable design process by letting the designers easily approach the concept of Eco-Friendly Design Process and applying this to Eco-Friendly Design Process when the designers perform design. Through a review on simulation, a research was made on the seriousness of environmental problems and control that was caused by design, Environmentally friendly design, sustainability, and sustainable design's background and definition were studied. In order to develop a Eco-Friendly Design Process, an existing review from Building Energy Simulation that proposed about energy environmentally friendly design element and sustainable design element's semantic similarities were restructured as sustainable design element comparative analysis. Restructured sustainable design elements and the relationship between sustainable design elements and the relationship of each product developmental process levels were analyzed. Finally, through clustering, sustainable design guideline were developed. This Eco-Friendly Design Process is expected to be applied to as one of the methods in solving the global environmental issues in design practice.
