This study reviewed a recently developed environmental education model 'ENVISION' and analyzed the value of the ENVISION program with environmental education(EE) perspective. Also this study proposed a prototype model of a inquiry-based water environmental education model with watershed concepts as a result of discussion of tills research. In the review of ENVISION, this research followed the theoretical framework of 'Inquiry-Based EE' that was previously proposed by the author. The ENVISION was characterized in tills research as two directions: watershed and scientific inquiry. Tills research argued that the watershed concept has a potentially very good meaning in EE because watershed enables 'holistic' view in EE area, and that the scientific inquiry in ENVISION seeks evidence-based explanation about local watershed environmental problems. That belongs to the scientific inquiry, which is also 'Inquiry-Based EE' and has internal value under EE perspective. Finally, this research proposed a prototype EE model that is about watershed concept, and is based on inquiry as general sense (scientific and insightful inquiries) and 'Environmental Studies for EE, (ESEE)' as the inquiry directions. The proposed model can be said a combination of the watershed concept and inquiry-based EE, and it seems that the model materializes better the EE nature than the ENVISION model.

부분들이 서로 긴밀하게 연결되어 있고, 상위 수준이 하위 수준을 제약하는 관계를 이루고 있는 체계를 위계라 한다. 여기서 백두대간과 관련 산줄기의 관계를 보여주는 틀 안에 위계 개념이 들어 있는 점과 특히 우리나라 국토가 위계 개념에 의해서 여러 개의 유역으로 나뉘어 지도로 표현된 사실들을 지적한다. 백두대간과 그것의 하위 단위인 정맥은 유역뿐만 아니라 기후적인 특성에서도 위계적으로 나타난다. 백두대간과 관련된 이러한 개념은 적어도 1402년 이전에 있었던 것으로 옛 지도에서 확인할 수 있다. 이러한 개념에 바탕을 두고 한국 경관의 전형적인 짜임은 유역 안에서 마을과 주변 경관 요소들의 특이한 배치로 나타나는데 이는 땅과 문화에 대한 위계적 접근과 관계가 있을 것이다. 그러한 개념에 바탕을 둔 현재의 실천양식들 또한 의미가 있지만 개념의 내실화와 발전을 위해 다양한 연구가 필요하다.

PURPOSES : Ambiguous decision on whether rural or urban area for road design can increase the construction cost and restrict the land use of surrounding area. However, administrative classification on rural and urban area is not directly related to road design because of this classification is not based on the engineering viewpoint, so method which can explain the road design context is required. METHODS : Method which enables to identify the area for road design is suggested based on the deceleration expected to be experienced by drivers who use the road section concerned. Deceleration rate corresponding to the area such as rural or urban suggested in Road Design Guideline is used as the criteria to identify the area by comparing this value with the estimated deceleration rate at the road section concerned. Speed profile method is utilized to derive the deceleration rate, and speed estimation way for reflecting both road geometry and intersection is suggested using stopping sight distance concept. RESULTS : The procedure of the method application is suggested, and the design example utilizing the method is provided. CONCLUSIONS : The method is expected to be used to identify the area for road design with engineering viewpoint, and design consistency among the roads with similar driving environment can be made.

Earth science is the study to explore the planet in which we live. Among these earth science geology of the area it can be the most critical and important study. However, because of the size and scope is too broad temporal spatial eurona covered in geology is true that many students find difficult about the geology field. In this study, in conjunction with landscape formation of geologic time for the concept to be among the core areas of Geology examined the concept and recognize it as the destination for high school students. Is a test tool for the analysis was adapted for use by Jolley (2010) has developed LIFT (The Landscape Identification and Formation Test). Currently we fix the strip to match the country through a validity check of the curriculum. Results of the study were as follows: First, the ability to check the landscape and formation is expected to estimate the time and the liberal arts students was higher than the natural science students. The reason for this seems to be the influence of learning geographical subjects. Second, the concept of geological time was found to lack both natural science and liberal arts students. The reason is that the students in the previous process because it deals with the concept of geologic time from the top of Earth Science Education II seems to be because there was no chance of learning about geological time. Third, the results confirm the confidence of the students surveyed in the landscape formation time natural science students was higher than liberal arts students. The research measured gender boys higher than girls. Fourth, the students on the landscape and geological time was found to have a number of misconceptions. This appears to be due to the students to feel difficulty in thinking of the concept because the need to understand the abstract geologic time. Therefore, it is necessary just to hold misconceptions about the concept of geology students have through the study of the landscape and geological time.

This landscape design proposal was presented for a competition for mixed-use development project by project financing in Asan Baebang which was held by the Korea National Housing Corporation in July of 2005. The site is a center of Asan Baebang New Town Development District and has a commercial area of $57,929m^{2}$. Design guidelines and judging criteria of this competition were to build a symbolic center and cultural core for district, to elevate positive image and identity of Asan New Town by attractive place making, to link with separated block in the site and regional context, and to make environmentally sustainable design by creating an attractive waterfront of Jang Jae stream passing through the site. This is the most important condition for the design. Therefore, the authors developed design concept and strategy within the guidelines and this conditions. The schema of the design was introduced by the water in the site. To evolve design concept, we reinterpreted water and context in the site combining with landscape design strategy. So the proposal set the main design concept as 'all that is solid melt into water' as if Marshall Berman said. By doing that, design concept of the proposal evolved as follows: 'extension' of water and greer, 'a joint' of space,'newness' of experience, 'breath' of consensus with each other. The spatial concept of this project was developed by expressing five theme spaces; eco zone, entertainment zone, art zone, culture zone, leisure zone. These theme spaces were consecutively placed along the pedestrian path and to consists of vertical layer in each level and diverse design technique and spatial effects are used.

The purpose of this study is to elucidate the concept of the internal value of environmental education (EE), and to present a new concept of 'Inquiry-Based EE' as a method to realize the internal value of EE. Since the introduction of EE, the 'external' value has been overwhelmingly present, as is shown in the commonly expressed purpose of EE. The ultimate goal of EE has been considered as to solve environmental problems through educational approach, which is important, but external value in relation with education. Generally, education has its own value, which may be more important than external value. But in EE area, that idea has not been discussed much. So, this study argued that EE has, or should have, the internal value of education. This study also examined the concept of inquiry, and presented it as two types of inquiry: the scientific inquiry and the 'insightful inquiry', and argued that the insightful inquiry is important as well as scientific inquiry in EE. Then, this study presented a new concept of 'inquiry-based EE', which can be defined as EE that is based on both the scientific and insightful inquiries, and makes the student be able to 'see' the world with the environmental world view. Lastly, this study presented also a new concept of 'Environmental Studies for EE, (ESEE)'. This means that the traditional environmental science is considered to be not well developed under the perspective of EE. From this viewpoint, this study presented the needed contents of the conceptually presented ESEE. In short, this research asserts that 'inquiry-based EE' is needed to make students 'see' the world environmentally, which is the very important value of EE, the internal value of EE, not very much examined. The 'inquiry-base EE' is considered to possibly advance EE as a new paradigm.
