'한강의 기적'이라는 말이 있듯 우리나라의 근대화, 산업화는 그 어느 나라에서도 유래를 찾아볼 수 없을 만큼 눈부신 성장속도를 자랑한다. 그러나 근대화, 산업화라는 명분 아래 우리에게 너무나도 고마운 존재인 자연환경에 대한 외면은 이미 수많은 부작용을 낳고 있다. 그 예로 우리 생활환경에 아주가까운 물인 하천은 심각하게 오염되고 더 이상 오염되어 가는 하천을 그냥 두고 볼 수 만은 없는 일이 되어 버렸다. 이러한 필요에 의해 몇 년 전부터 활발하게 이루어지고 있는 하천의 개보수공사는 석축 쌓기, L형 옹벽 및 돌망태, 견치석 등을 사용하고 있는데, 이는 하천의 생태계를 단절시키는 또 하나의 문제를 야기하고 있다. 또한 이런 과정을 통해 하천이 직선화되면서 홍수가 났을 경우 피해를 가중시키고, 자연석을 고갈시키는 등의 문제점이 대두되고 있다.

This paper is to reclassify systematically the functions of urban river: that is, water supply, land management, transportation and energy source as social and economic function; formation of geomorphic surface, water-side landscape, community constitution and boundary and separation between regions as spatial function; and drainage of waste water, purification, habitation, and weather regulation as ecological function. On the basis of this reclassification, it can be argued that the socio-economic functions (eg. water supply) of the river among the functions of the river have been strongly mobilized in the process of modernization, while the spatial function and ecological function of urban river have been ignored. The Kumho river which flows through Daegu and the adjacent area has made a great contribution to the modem development process of the river basin area, but as a result of a selective development of a specific function of the river, that is the social and economic function, it now suffers from the lack of instream flow and is deprived of its original functions with the water pollution and degradation. Moreover the Daegu region seems no longer possible to develop on the dependence of the river. In order to overcome this kind of social and environmental crisis, this paper is to suggest both some principles and main evaluating indicators to restore the original and comprehensive functions of the river, and important measures to make the co-evolution of the city and the river possible.

In order to plunder the Korean Peninsula in earnest, 'Modern Age Korea Topographical Map' of reduced 1:50,000 scale was manufactured within the period of 5 years from 1914 to 1918 through Japanese government-general of Joseson. This map includes all the data representing the life model of Korean Peninsula in the period of the End of Korean Empire, before the modern public construction works had started to seriously develop. This study analyzes the land use change after embedding the coordinates to the image of Modern Age Korea Topographical Map, which includes the scenery of 1910, and then overlaying it with the contemporary map in GIS environment. The results of presented research showed that before modern civil construction works started, the farmlands had lost their competitiveness because of difficult for development hilly areas and frequent floods, the river sites being abandoned and industrial structure change, and were developed into modern city area.

인류가 수렵생활에서 농경문화로 정착됨에 따라, 물을 손쉽게 이용할 수 있는 하천이나 호소의 수변공간을 활용하여 고대문명이 형성되어 왔다. 이와 같은 고대문명이 근대 산업화에 의한 새로 운 문명으로 이어지면서, 종래의 하천이나 호소의 수변공간을 이용한 생활과 문화로부터 대외지향적인 해안공간을 중심으로, 그것이 확장되기에 이르렀다. 특히, 최근의 세계화에 수반되어 많은 국가들이 대외지향의 편리성 도모를 위하여, 일종의 제2의 도시국가형태의 문화가 이루어지면서, 새로운 형태의 문명이 태동하고 있는 듯하다. 이와 같은 배경에서, 우리나라는 저 출산 고령화 사회라고 하는 새로운 조류가 긴박하게 진전되고, 도시화율이 90%, GDP의 대외 의존도가 80%에 육박하고 있는 등으로, 고도의 수변공간을 활용하는 세계 유수의 도시국가의 형태로 이행되고 있는 듯하다. 그러므로 종래의 하천 호소 해안 등의 수변공간의 이용을 위하여 발전시켜온 하천공학이나 해안 항만공학만으로서는 이러한 변화에 대응하가가 미흡하고, 더욱이, 20세기후반으로부터 시작된 환경적요인의 도입에는 아직까지 혼란이 야기되고 있어, 새로이 형성시켜가야 할 수변문화의 효율성제고의 도구로서의 새로운 공학의 발전이 모색되어야한다. 이는 수변공간의 이용 안전 환경이라고 하는 큰 틀로서의 문화 문명을 만들어 갈수 있는 공학이어야 할 것이다. 기존의 수공학 위주의 공학개념에서 종합공학 또는 공학종합의 학문으로서 인문사회, 첨단과학기술까지의 대융합을 고려한, 장소나 공간이라고 하는 "것(물(物))"의 디자인뿐만 아니라 장면, 상황, 규칙 만들기라고 하는 "일(사(事))"의 디자인까지도 포함되는 공학의 새로운 모델을 제시한다. 주요내용으로서는, 새로운 수면문화조성을 촉진하여, 지속가능한 인류문명이 유지 될 수 있도록 지금까지의 터 무늬 또는 자취를 최대한 살리면서, 최근의 하천 해안을 중심으로 한 외부의존형 대도시권형의 국토이용에서, 지식산업단지 생산녹지 등을 최대한 아우를 수 있는 소위 글로발형의 국토이용을 촉진할 수 있는 수변문화공학의 모델을 제안한다.

Growth, inorganic solutes and glycine betaine accumulation in spinach beet (Beta vulgaris var. cicla L.) were studied under different salt conditions. Plants of fortythree days old were assessed by growing for a further 10 and 20 days at four NaCl concentrations (0, 100, 200, 300 & 400 mM). The dry weight of leaves was maximal in plants which were grown at 100 to 200 mM NaCl treatments and after 10d it was decreased slightly at salt treatments of more than 300 mM NaCl. Under the salt conditions, leaves of B. vulgaris contained high inorganic ions to maintain low water potential, but low water soluble carbohydrate contents. Total ionic content and osmolality increased with increasing salt concentration. Salt stress led to a preferential accumulation of glycine betaine in leaves of B. vulgaris, especially for the 200 mM NaCl treatment. These findings suggest that a high degree of NaCl tolerance of B. vulgaris resulted from the accumulation of glycine betaine, which is known to have osmoprotectant properties in the cytoplasm.

This study centering on 10 village - Bangjuks analyzed multifunctionality value of village Bangjuks which have been main water treatment system in Korean traditional villages. On the basis of understanding the structure and character of components such as the well, common spring, village waterway and others which making water-flow and consisting of aquatic system in Korean traditional village Bangjuk, the conclusion as the instrumental device of social and ecological role and ecological watershed management, securing the ecosystem soundness of the damaged or deteriated aquatic ecosystem due to the industrialization and urbanization is as below; 1. The traditional village Bangjuk was environmentally friendly hydraulic system which gathers waterways of village into a point including sewage water, retains and flows out to village through agricultural waterway. Through this Bangjuk, they have managed sewage and rainfall runoff flowed out village efficiently. It is not only a detention system of water but a kind of eco-friendly system that flow out water into the rivers after reusing and filtering it. 2. Around five traditional villages and five villages after modernization, this study classified the types of village Bangjuk as three types considering geographic location, size, etc; marsh type of low swamp, high water -low rice field type of natural flow stucture, low water - high rice field type requiring artificial irrigation facility. All the five traditional villages were turned out to be marsh type of low swamp. Geoji, Sanjeri, Ma-am, Yangchon of the agricultural villages were high water-low rice filed type, and Sangchoenri village was classified low water-high rice field type. 3. This study checked up the function of water purification of village Bangjuk. In Wonteo and Geji villages affected by discharge of village sewer and domestic sewage, the efficiency of ammonia nitrogen($NH_3-N$) and total phosphorus(T-P) was 56~95%, which was high. In Sangcheonri and Sanjeri villages strongly affected by stall and farmland, the efficiency of suspended solids(SS) was 70~85%, and that of total nitrogen(T-N) and total phosphorus(T-P) was 5.3~65%. 4. A water purification system can be found out in the system of village Bangjuk that filter out village sewage and rainfall runoff flowed through the settle and filter of pollution source and denitrification of plants. Through this system of village Bangjuk, it must be used as the basic facilities for the ecological watershed management. The sewage management system of village Bangjuk as a eco-filter must be used and studied as an eco-friendly facility for the ecological watershed management around the subwatershed and catchment.

The proximities of Cheonggye creek was a maj or space for the gathering of large populations from the past times and it is also a place containing the joy, anger, sorrow, pleasure and lives of the citizens. The Cheonggye creek which flowed downtown of Seoul throughout many historical events had disappeared into history completely in the modernization process due to the contamination with life sewages and overflow. However, the city authority of Seoul decided to restore it to its shape before covering the creek by means of dismantling the old elevated ways in Cheonggye creek in line with the Large Scale City Movement Project to revive the grey city and to improve the quality of the city landscape in 2002. The cultural space was created by activating the old town sphere in Cheonggye Creek and the amenities of the giant city was improved by the cultural and natural wave created along the creek. In addition, the educational opportunity has been provided to the citizens by means of reviving its historical nature. The design and cultural value of the Cheonggye Plaza were restored for the mean time and the urban environment requested during modem times was established. The Cheonggye Plaza which heightened the balanced development in Seoul which has been developed in an unbalanced way by dividing into northern and southern area of the river is very meaningful in the viewpoint of the landscape architect who designs the urban space. The re-birth as a cultural space of downtown owing to the efforts of the said cultural catalysts is meaningful.

Ran Gang is a huge, attractive river which meanders through Seoul, the capital of South Korea. However, during the modernization of Seoul, the river gradually lost its natural beauty and healthy condition. Han Gang Renaissance is a project to upgrade the look of the Seoul waterfront, by overcoming this disaster and reorganizing the surroundings of Han Gang. This research articulates the design strategies and description of the prizewinning work of the International Design Competition for Yeouido Riverside Park that was linked to the Han Gang Renaissance Project. There are three key points that basically speak to the identity of the new waterfront, Yeouido Riverside Park. First, the current day Yeouido was recreated as an artificial island through the rapid expansion of the city and the initiation of the shore protection works. However, because it is the only island still remaining that shows the history of Han Gang, the park was designed to be the place which preserves the lyric of sand island and the emotional memory of riverside. Secondly, among the six districts of the Han Gang Renaissance Project, the two districts that are facing each other, Yongsan and Yeouido, are the central areas promoting international finance and business. Despite Yongsan's complete urban image, the exquisite harmony of pastoral scenes and skyscrapers of the Yeouido waterfront is presented to develop an active mutual relation with Yongsan. Lastly, this design scheme re-establishes the relationship between this competition's site, Yeouido Riverside Park, and a neighboring site, Yeouido Park.
