DMZ is considered as an ecologically sensitive landscape and one of the highest biodiversity regions in the Republic of Korea. There have been, albeit the significant value, increased interests in developing this region for a variety of purposes including tourism and commemorative events. As this region has been already facing a range of problems derived from previous development, natural disaster and invasive species, the necessity for active management of ecological health within this region has been increased, which weighs the importance of executing ecological restoration. The objective of this study was to develop evaluation indices as an effective management means of properly evaluating ecological restoration and sustainably maintaining the restored conditions on a long-term scale. Through literature review existing evaluation indices related to restoration were collected, and then the most suitable indices were selected based upon two interviews and one questionnaire survey targeting experts in the relevant field to ecological restoration. They were categorized by two major division and their subclasses (Ecological base - vegetation structure & composition, habitat characteristics, soil environment; landscape ecology - connectivity, landscape patch, boundary & surrounding) and 40 indices. These indices were considered helpful to comprehensively evaluate ecological restoration on degraded environments within ecologically sensitive areas, and sustainably manage target areas by employing a long-term monitoring approach. As this result played a meaningful role in providing the fundamentals of evaluating ecological restoration, it should develop a suitable evaluation system through further research.

The purpose of this study is to construct the evaluation criteria based on the relative importance and various combination of each evaluation index and then to evaluate urban biotope in terms of conservation of species and habitat. After the standard of evaluation had been developed through the literature review, the relative importance of the evaluation index through expert survey was found out, and the evaluation model of biotope value has been established. The results of this study are as follows; 1) We have constructed the nineteen evaluation criteria through literature reviews, and have provided relative importance to each evaluation index of the diversity of typical species in biotope, afforestation rate, stratification, Hemeroby grads, and the diversity of landscape patterns based on the results of expert survey. and then we have constructed the evaluation system using the relative importance criteria. 2) To evluate urban biotope using the evaluation system constructed, we selected 14 sites. The final evaluation results of each site is as follows; The III grade areas are Seohan and Hwasung high-rise apartment at Beummul-Dong, Korea Men Power /Agency in Sungs 대 industrial zone, the adjacent area of St. Tongil, and Hyomyung elementary school. The II grade areas are the farm land behind the third Anshim Jugong apartment, and Ehyun park. The I grade areas are swampy land in front of Kangchon and Anshim construction site, water space with semi-natural style in front of Gangchon Woobang apartment, forest zone near page Temple at mt. Palgong, the edge area of Jisan and Gosan, and the tendril yard against Anshim middle school. The only grade IV area is the commercial zone near Taegu Department 3) It is highly useful to evaluate urban biotope using the evaluation criteria constructed for this research, the evaluation criteria we developed may be difficult to guarantee the ability for reproduction and recovery, the appearance-number of the rare and endangered species are difficult to estimate urban biotopes. In the future, it is highly useful to evaluate biotope in terms of conservation of species and habitat through its valuation criteria developed in this research and it is necessary to develop the evaluation criteria applicable to estimation of biotope inventory and reproduction of biotope.

While the recent lift of restrictions in greenbelt areas is expected to generate a number of development plans, there are efforts to create various development plans into spatial plans that consider the natural and ecological conditions of development sites. However, these development plans consider Degree of Green Naturality or Degree of Ecology only when designating areas for conservation within development sites. It is true that they don't fully reflect the value of green areas and wetlands as habitats and natural resources. Therefore, this study built an conservation value assessment model that is applicable to sites where development is planned in Korea by reviewing prior case examples md studies and applied the developed model to a case study area. The site where the conservation value assessment model was applied to is an area around Yongsan-ri and Suha-ri, Doam-myon, Pyeongchang-gun, Gangwon province where quality natural resources are located in and wend the site. This is a site for the development of Alpensia Resort where a resort including facilities for the Winter Olympics is planned to be introduced. In order to assess the conservation value of the site for Alpensia Resort, a total of eight items including area, distribution of communities, habitation of species with conservation value, functions of habitats, connectivity of habitats, vegetation layers of forests, age of forests, and ratio of non-native plants were studied through literature review and field surveys. The assessment was made by dividing the site into 95 habitats that are perceived by aerial photographs and each habitat unit was assessed on the eight items in a 3-point scale. Each unit habitat assessed in a 3-point scale was segmented into primary, secondary or tertiary areas based on the conservation value. Habitats assessed as primary were designated as priority (absolute) conservation areas and those assessed as secondary and tertiary were set as secondary conservation areas and tertiary conservation areas, respectively. As a result, each area represented 26.9%, 20% and 3% of total site area. Based on this result, habitat management plans were developed to conserve primary conservation areas, improve secondary conservation areas and restore tertiary conservation areas. In addition, a development plan was developed to create habitats in areas where new habitats are requested in order to build an eco-network in the site and a plan to create eco-corridors was proposed. In developing a land use plan for the site, a development plan that considers conservation areas first should be set up based on the outcome of conservation value assessment. This can be linked to the development of an environment-friendly land use plan as well as easing the establishment of a green area and eco-network. This study will facilitate the implementation of the 'conservation before development' principle, which can prevent reckless development, by assessing conservation value in setting up development plans.

This study aimed at reviewing the case examples of environmental assessment of development projects within management zones, identifying problems and improvement opportunities and suggesting the direction of environmental assessment for management zones that are increasingly segmented Findings showed that first, the assessment of environment soundness in management zones must incorporate the national land environmental map and wide-area ecological axes established by the Ministry of Environment. Second, regarding development activities in management zones, rather than an issue of simply destroying natural environment in a development site itself during a development period, an issue of permanently isolating ecosystems from surrounding areas in a mid/long-term perspective and continually polluting water in mid-stream/upstream regions where sites are located must be considered. Third, in the case of development projects with vast areas, existing plant communities will be disturbed and the naturalness of vegetation will gradually decline due to foreign tree species introduced for landscape architecture. Therefore, creating buffer forests at forest boundaries and planting native tree species that are same as nearby tree species must be examined. Last but not least, when assessing the environmental soundness of management zones, it would be crucial to comprehensively review the environmental, social and locational features of management zones, including surrounding areas, and set the direction of environmental assessment accordingly.

Research over the years has progressively and sequentially provided near complete resolution of regulators of the DNA repair pathways which are so important for cancer prevention. Ataxia-telangiectasia mutated kinase (ATM), a high-molecular-weight PI3K-family kinase has emerged as a master regulator of DNA damage signaling and extensive cross-talk between ATM and downstream proteins forms an interlaced signaling network. There is rapidly growing scientific evidence emphasizing newly emerging paradigms in ATM biology. In this review, we provide latest information regarding how oxidative stress induced activation of ATM can be utilized as a therapeutic target in different cancer cell lines and in xenografted mice. Moreover, crosstalk between autophagy and ATM is also discussed with focus on how autophagy inhibition induces apoptosis in cancer cells.

Roadside native vegetation provides important habitat for plants and animals, and provides visual amenity and beauty for drivers and rural areas. In particular, native wildflowers create and maintain attractive landscaping and scenic vistas while help protect and restore the natural environment. However, it is lacking in government policies and guidelines about using native wildflowers for roadside vegetation and alien invasive plants are a major threat to our environment. The purpose of this study is to review the regulations and programs for roadside vegetation, especially native wildflowers in USA in order to learn lessons about developing wildflower policies in Korea. A summary of results follows: (1) the goals of roadside vegetation have been shifted from beautification for pleasant driving experience to sustainable and economical maintenance. (2) Various funds and laws by federal and local government are essential for native wildflower planting and roadside enhancement. (3) Ongoing projects on seed collection and seed banking of native plants are conducted by wildflower research centers to conserve and propagate endangered plants. (4) Recognizing that wildflower viewing holds tremendous potential, increasing local governments try to grow wildflower tourism for economic benefits. In conclusion, we should establish a long-range plan and regulations on roadside wildflowers planting in order to create safe and sustainable transportation corridors in Korea. In addition, more research on wildflower habitat and propagation should be warranted and landscape architects should play a definitive role in providing pleasant driving experiences and promoting wildflower tourism.

Since the great acceleration, the emergence of the sustainable development concept amid the conflict between economic growth and the preservation of the natural environment is at a time when an efficient land-environmental plan integration system is needed to achieve a smart balance between development and conservation. Although preceding studies have been conducted domestically and internationally on various aspects, the operating system has not been implemented effectively. In this study, the policy concept of environmental policy integration, the current status of integrated management of land-environmental plans in South Korea, and related literature studies were reviewed to derive overall complementary points. In addition, the review was carried out by reorganizing the domestic urban planning legal-based system and the environmental legal-based system according to the same hierarchy to promote an effective integration system, and in foreign cases, the establishment of spatial and environmental plans in Germany and Japan was typically considered to derive implications for the establishment of an efficient interconnection system for the integrated management of domestic land-environmental plans in the future.

본 연구는 선조가 꾸민 전통조경공간 내에서 발견할 수 있는 특징적인 바위글씨인 동천(洞天)을 대상으로 하여 그곳에 담긴 의미는 무엇인지, 어떠한 목적으로 동천을 조영(造營)하였는지, 또한 조영함으로써 무엇을 나타내고자 하였는지를 밝히고자 하였다. 이를 위해 집중적인 연구대상지인 25개소의 동천을 선정하고 이곳에 대한 이해를 뒷받침해줄 수 있는 자료에 대한 문헌분석, 그리고 현지답사를 통해 동천의 경관과 유형을 살펴봄으로써 나타난 조영 특성은 다음과 같다. 첫째, 동천은 조성 목적에 따라 가거지형(家居地型), 은서지형(隱棲地型), 산수유람형(山水遊覽型)에서 승경형(勝景型)과 수신형(修身型), 수도지형(修道地型)으로 나눌 수 있었다. 즉, 동천은 우리의 생활하는 장소에서, 현실의 불합리나 재난을 피하기 위한 은서의 장소에서, 자연과의 화합에 의한 풍류생활의 장소에서, 그럼으로써 자신을 수양하려는 수신의 장소에서, 속세를 벗어난 수도의 장소에서 조영되어 있었다고 볼 수 있다. 둘째, 입지유형에 따라 심산동구형(深山同口型), 계류인접형(溪流隣接型)에서 연계형(連繫型)과 단일영역형(單一領域型), 평지형(平地型)으로 나눌 수 있었다. 특히 심산동구형은 무릉도원, 몽유도원, 오복동에서 보여주는 공간설정과 상당히 유사하게 전개되어 동천이라는 것이 선조가 사유했던 이상향의 공간구조임을 알려준다. 그렇지 않다면 우리나라의 계곡, 승경처에 동천이 조영되었는데, 이는 신선사상에서 말하는 선계의 모습을 원림에서 가꾸어 나감으로써 신선의 경지를 추구하고자 한 바램으로 파악된다. 셋째, 동천이라 명명함으로써 그곳은 이상향이 되며, 그 스스로 선경을 유발시키게 된다. 즉, 눈에 보이는 동천각자를 통해서 이면의 심층에 있는 이상향의 의미를 추구하려는 것이며, 공간을 만든 조영자가 추구했던 이상적 세계에 대한 갈망에 지극히 기여하는 요소가 되고 있다.

Since the government of Korea (Ministry of Environment, MOE) introduced the policy applying 'Biotope-Area-Ratio-Indicator (BARI)' to huge residential land developments which Environmental Impact Assessment (EIA) should be performed, MOE has come to have the necessity to apply the indicator concretely at the stage of Prior Environment Review System (PERS) and EIA in various types of large scale land development projects. This study was conducted with the aim of supporting the application of BARI and related decision making in various other types of EIA projects as well as residential development projects through remodeling the system to apply the indicator of the past. Through the analysis of the problems in applying the past BARI and experimental appraisals to 11 types of EIA projects, the results and implications as follows were drawn. First, it's possible to extend the range of applications of BARI, which has been applied to only residential land development project, to all kinds of projects with area-typed land use pattern out of environmental impact assessment target projects. Second, it's also possible to set a target value into which regional characteristics and differences among locational properties are reflected. In addition, it's come to be able to differentially apply the target value of BARI according to the condition of the existing site. Third, it's improved to be able to suggest a macroscopic target value at the stage of PERS and to set detailed target values in each detailed land use at the stage of EIA. The key point underlies inducing methodology to determine target values to secure more permeable land coverage ratio for detailed land use patterns at the stage of EIA by making it possible to calculate BARI of the present land cover condition of the EIA target projects.

10 years ago, in Sijeon-ri, Dogo-myeon, Asan-si, the existing stream was repaired to develope Mt. Dogo trail and irrigation systems through road expansion pavement construction and small stream repair construction. The trees such as persimmon and willow are eliminated that rowed on both sides of the stream and dredging work to dig the rock and sand have been performed. As a result, wide asphalt road was built, also flood damage worries were reduced. 10 years passed and now, how did local residents think about the stream repaired before and after? Village residents, public officials, and the stream construction engineer were interviewed. Villagers indicated a problems that brook became a place where water peppers were taking over and water was stagnating due to the slow velocity so nothing could live and natural landscape like a wash place and the cascade disappeared, because rock and sand were taken out brought soil into the brook. Public officials and engineers were aware of the problems at the time of the stream. Now that construction is completed after 10 years, Both realistically and budgetary to restoration would be difficult. However, it is necessary to seek for waterfront space which can be restored or replaced by a part of the stream like similarly before. In addition, it is necessary to restore to the progression of a natural stream which connect with stairs(or slope) - small waterfalls - pools - wash place. In this paper, we hope to take a lesson from the Sijeon-ri model and make rural stream construction be prepared with consideration about not only distinct characteristics of specific area but also the opinion of local resident.
