해안과 만나는 하천의 하구부에서는 해수의 흐름에 따른 연안토사의 이동과 유황에 따른 하천상류에서의 토사유입량에 의해 하구부가 빠르게 변화한다. 본 연구대상지인 가곡천은 유로연장이 짧고 경사가 급한 산지하천의 특징을 가지고 있어 집중호우시 토사가 하류로 빠르게 유입되어 일반하천에 비하여 하구부의 지형변화가 크게 일어난다. 가곡천 하구부는 모래사장으로 이루어져 있는 호산해수욕장과 경관적 및 자연적 가치로 인해 보존 필요성이 대두되고 있는 하중도인 솔섬이 위치해 있다. 그러나 현재 솔섬 주변 하구부 인근의 일반산업단지 건설과 고향의 강 조성사업에 따른 하도환경의 변화로 하도를 유하하는 유수의 흐름 및 침퇴적 양상의 변화를 가져와 홍수의 원활한 소통에 지장을 초래하고 있다. 또한 현장조사 및 모니터링 결과 하구 지형변화로 인해 하도안정 유지관리에도 막대한 영향을 끼치는 것으로 확인되었다. 따라서 본 연구에서는 가곡천 하구부의 하도환경 변화에 따른 수리학적 특성 및 하천형태학적인 변화를 분석하여 하도안정을 파괴하는 요인을 규명하기 위한 연구를 수행하였다. 연구방법은 가곡천 하천정비기본계획의 빈도별 홍수량, 기점홍수위를 경계조건으로 2차원 수리해석 모형인 SRH-2D모형을 이용하여 하도환경 변화 전 후의 대상구간에 대해 수리특성 및 하상변동 양상을 모의하였다. 모의결과 하도환경 변화(홍수터 및 징검여울 등의 하천시설물 조성)에 따른 수리특성변동양상과 침 퇴적지점에 대한 변동경향을 확인할 수 있었다. 본 연구의 결과는 동해안 하구부에 위피한 하천의 다양한 변화 해석시 참고자료로 활용할 수 있을 것으로 사료된다.

Recently, the frequency of installation of ventilation towers is increasing due to the planning and construction of underground roads and long tunnel. In this study, implications and points for improvement were considered through investigation and analysis of the installation standards related to ventilation towers in tunnels and analysis of ventilation tower installation cases in domestic and overseas tunnel case study. As a result of this study, when selecting the location and height of the ventilation tower, it is recommended to determine the final ventilation tower type through a consultation process with residents, considering the environmental impact caused by the emission of pollutants, the harmonious arrangement with the surrounding landscape, and the efficient use of the above-ground site nearby ventilation tower. In addition, from the design stage, it is judged that a detailed review of reducing the height of the ventilation tower through air quality simulation is necessary for natural harmony with the surrounding topography and to prevent civil complaints.

This research aimed to analyse geomorphic resources of Mt. palgong(in Daegu city and Gyeongbuk province) through some field surveys, and then to clarify geomorphic features. The main results are as follows. 1) The geological boundary of the south slope(granite) is more clear than one of the north slope(granite bedrock and metamorphic sedimentary rock). Small basins are along with fault line between granite bedrock and metamorphic sedimentary rock. 2) It is estimated that relatively big valleys on the north slope are due to local climate, geomorphic and geological features. 3) Tor, sheeting joint, gutter are well developed both on the south slope and on the north slope, however the development of polygonal cracking and boulder stream are more dominant on the south slope; river cliff, pool, waterfall are more dominant on the north slope with valleys that well developed. 4) Scenic geomorphic landscapes are mainly developed in Dongsan valley and Chisan valley on the north slope. 5) There are many interesting geomorphic resources in the viewpoint of storytelling in Mt. Palgong. So the specific design to utilize such resources is required

This study aims to identify the value of Incheon Freedom Park as a 'historic urban park' through the historical transition process of the park and surrounding areas. To this end, this study uses a time series analysis, as research method, based on old maps and aerial photographs to investigate the changes in the park over time and to interpret them based on the historical and cultural changes in modern and contemporary history. As a result of the study, the park not only has (1) evidence of major events in modern and contemporary history, but also (2) historical value as an urban park based on the first urban plan in Korea, and (3) very important heritage value that shows the rapidly changing civic life in modern and contemporary times. However, despite the identification of heritage values in this study, further research is needed to explore and excavate in-depth data on the park in order to more clearly identify, restore, and utilize the heritage values of the park.

Places such as famous urban sights and foreign settlements have recently been created in Korea, which reflects the increase in social and cultural exchanges and the number of place-making and landscape-planning projects. Understanding place identity is required in environmental design and planning. This paper examined the components of the identity of place through comparison of perceptions of "placeness" between residents and visitors of Seo-Rae Village, Seoul, Korea. More than 40% of French nationals in Korea reside in the village, which many Koreans visit as an urban sightseeing place. Twenty-five French inhabitants and forty-one Korean visitors were surveyed. Insideness of Seo-Rae Village was formed by limited activities and needs of the residents, primarily children's education and food purchases. Residents mentioned that the physical environment, especially buildings, lacked theauthenticity of French style. The symbolic meaning of the French village influenced the visitors' activities. The authenticity of French style, however, did not affect the perception of visitors and outsideness of the place. Visitors' activities and cognitive meanings of the place were formed mainly by the commercial environment established by Korean investments. Commercialization of the place and related activities played an important role in establishing insideness of the place. The village shows the phenomenon of the reversal of insideness and outsideness. The "placeness" of Seo-Rae village has been shaped by visitors' tastes rather than the true experience of insideness. Mass identity formed by mass media using French characteristics influenced this phenomenon. Insideness formed by inhabitants appeared to be a pseudo-place, which was created by the French tastes of visitors and lacked French authenticity. Seo-Rae Villagerepresents a superficial cloak.

Changgyeongwon emerged as pleasure grounds following the creation of a museum, zoo and botanical garden in Changgyeonggung Palace during the Japanese colonial period. Pleasure grounds offer space for entertainment and have maintained the image of a paradise apart from reality. This study examined the creation process of pleasure grounds within a royal palace and the following spatial changes. By analyzing the image of Changgyeongwon as an artificial paradise, this study explored its landscape and cultural aspects. Literature reviews on the intention and process showed that the Changgyeongwon pleasure grounds were created as a 'royal garden' for the amusement of Sunjong, as well as 'public pleasure grounds' in the process of colonization. It was one of the first public spaces open to everyone who could afford the entrance fee. The layout of Changgyeongwon was studied by a comparison and analyzation of modern plans and photographs. It was composed of the central museum zone, northern botanical garden zone, and southern zoological garden zone. A conservatory and greenhouse to exhibit and maintain tropical plants were intensively built in the botanical garden zone while an aviary was created on the zoo pond. In the vicinity of the aviary a vivarium was constructed. Museum exhibition facilities included a main building as well as existing buildings, and a western flower garden was created between the buildings. Space for children including a playground and horse-riding course were created in the 1930's. The paradisiacal image and pleasure grounds culture of Changgyeongwon were studied as follows. Firstly, it shows that Changgyeongwon's paradisiacal image where rare animals and exotic plants were open to the public was promoted by the zoo and botanical garden. This led to the creation of new popular leisure activities such as flower appreciation and animal watching. Secondly, Changgyeongwon offered an urban leisure space, symbolizing the 'non-urban nature within the city' where the urban residents could escape from the daily routine. Thirdly, Changgyeongwon was known for its 'fantastic night landscape' by its night opening during the cherry blossom season. This cherry blossom viewing at night sadly degenerated by various shows and drinking, and as a result, an image of a deviant paradise was given to Changgyeongwon. Changgyeongwon contributed to creating a new space with its diverse facilities, and the public embraced the urban culture through experiences of pleasure and entertainment.

Currently, the object of conservation in heritage conservation is defined as "the value of the heritage" and the value-based management plan has been introduced. Most of traditional temples in korea have been sustained over 1000 years, which make them mixed heritages, including cultural, religious and natural heritages. Therefore, traditional temples should be managed by value-based management plans. This article aims to develop the values and assessment indicators of traditional temple areas and to evaluate the importances of the values and indicators, in order to prepare the basic materials for conserving the values of traditional temples. This study used the diverse research methods such as literature review, in-situ survey, in-depth interview, focus group interview, questionnaire survey. The results showed that the identified values and assessment indicators of traditional temple area were defined as three classes: high class value was consisted of intrinsic value and use value, middle class values were 10 (5 for intrinsic and 5 for use value). 5 middle class values belonging to the intrinsic value were religious/humanity, historical, cultural, environmental/ecological, landscape values. 5 values constituting the use value were social, educational, therapeutic, recreational, and economic values. As a low class, 102 assessment indicators were identified. 60 participants (30 buddhism people, 30 KNPS people) evaluated the importances of the developed values and indicators, using the pairewise comparison for the values and the interval scale for the indicators. It was found that both groups evaluated the use value more important than the intrinsic value and that religious/humanity, landscape, environmental/ecological, economic, recreational values were evaluated more important than the other middle class values. It was also revealed that the two groups were different in their assessments of the indicators. Based on the results, some suggestions were made to improve the management of the traditional temple areas.

본 연구는 VGIS(Virtual Geographic Information System)을 이용, 환경친화적인 도로건설을 위해 실제 좌표를 사용하므로 3차원 도로의 선형과 구조물을 설계하였다. 그리고 시공 중에 발생 할 수 있는 민원문제 및 설계변경 시 효율적인 의사결정 할 수 있도록 하였다. 대상지역은 전라남도 장흥군의 최대 역점사업인 관광을 테마로 한 정남진 가는 길을 컨셉으로 한 '가고 싶은 길', '보고싶은 다리', 기억하고픈 터널'을 주제로 설계하였으며 명실공히 남도의 새로운 관광명소가 될 자연관광도로가 될 것으로 기대된다. 기존의 3차원 설계에서는 평면적인 선형과 구조물의 형상을 이해하는데 상당한 시간이 소요되었지만, 구조물을 3차원으로 설계함으로써, 비전문가라도 구조물을 쉽게 파악 할 수 있었다. 그리고 3차원 설계는 기존 구조물과 신설될 구조물 사이에 공사 중 발생할 수 있는 환경 및 민원문제를 사전에 파악할 수 있었다. 또한, 실제와 같이 구현된 도로와 구조물의 시뮬레이션을 통하여 기존의 각종 의사 결정에 있어 보다 시각적 효과를 증진시켜 효율적인 의사결정을 가능하게 하였다. 본 연구에서는 실제 평면 설계에 쓰이는 좌표값을 3차원설계에 적용하였다. 도로 노선 및 경관분석에 많은 도움이 될 것으로 보이며 VGIS를 이용하므로 도시계획, 식물, 토양. 수로 또는 도로형태, 홍수계획 등 많은 일들이 평가에 사용된다. 여기서는 구조물 3차원 설계에 관한 기초적인 연구를 시행하였으며, 3차원설계를 통해 의사결정시 효율적인 판단을 할 수 있었고, 환경 친화적 시공 및 설계에 대한 연구가 이루어져야 될 것으로 판단된다.안전관리를 위해 채석장에 안전표지판을 설치하여야 하며, 실내가공 작업장의 자동이동시스템을 작업별로 채색하여 식별을 용이하게 하여야 하겠다. 또한 이 연구 결과를 영세사업장의 산업간호프로그램인 'Clean 3D'사업에서 적용하여 우리나라 채석사업장 근로자 건강관리를 발전시켜야 하겠다. 확장기 혈압에서 RZS와 DAD의 일치도와 평균을 중심으로 더 넓게 퍼져있어 낮은 일치도를 보였으며 또 DAD와 RMS의 혈압치는 숫자 선호도를 볼 수 있는데 특히 RMS는 더 뚜렷하게 나타났는데 확장기 혈압의 최빈치(30.6)는 100mmHg이었다. 혈압치들이 가장 가까이 "0"점으로 치우쳐져 있었다. RZS의 Central tendency는 DAD와 RMS보다 뚜렷하였다. 결론적으로 RZS는 이 연구목적으로 가장 적절함을 보여준다.청소년들의 학교급식에 대한 만족도를 높이기 위해서 다음과 같은 제언을 하고자 한다. 먼저, 학교급식에 대한 식단 작성 시 학생들이 학교에서 제공되기 원하는 식단에 대한 의견을 받고 그 의견에 대한 결과를 게시하여 학생들이 제공되기 원하는 식단을 급식 시 제공하여 학생들이 식단선택에 동참할 수 있는 기회를 주는 것이 바람직하겠다. 또한 영양사는 학급의 반대표와의 정기적인 모임을 가짐으로서 학생들의 불만사항 및 개선 요구사항에대해 서로 의견을 교환하여 설문지조사가 아닌 직접적인 대화를 하여 문제점을 파악하고자 하는 적극적인 자세가 필요하겠다. 특히 아침식사의 결식 빈도가 높았고 이는 급식성과에 부정적인 영향을 줄 뿐 아니라 학교에서 제공하는 음식의 섭취정도에도 영향을 주고 있으므로 학생들에게 학부모와 전담교사 및 학교영양사는 학생들

The purpose of this study is to select the study area, which will be formed into Daegu Science Park as an national industrial complex, and to assess the landscape value based on biotop classification with different polygon forms, and to develop and computerize Biotop Value Assessment Tool (B-VAT) based on GIS. The result is as follows. First, according to the result of biotop classification based on an advanced analysis on preliminary data, a field study, and a literature review, total 13 biotop groups such as forrest biotop groups and total 63 biotop types were classified. Second, based on the advanced research on landscape value assessment model of biotop, we development biotop value assessment tool by using visual basic programming language on the ArcGIS. The first application result with B-VAT showed that the first grade was classified into 19 types including riverside forest(BE), the second grade 12 types including artificial plantation(ED), and the third class, the fourth grade, and the fifth grade 12 types, 2 types, and 18 types respectively. Also, according to the second evaluation result with above results, we divided a total number of 31 areas and 34 areas, which had special meaning for landscape conservation(1a, 1b) and which had meaning for landscape conservation(2a, 2b, 2c). As such, biotop type classification and an landscape value evaluation, both of which were suggested from the result of the study, will help to scientifically understand a landscape value for a target land before undertaking reckless development. And it will serve to provide important preliminary data aimed to overcome damaged landscape due to developed and to manage a landscape planning in the future. In particular, we expect that B-VAT based on GIS will help overcome the limitations of applicability for of current value evaluation models, which are based on complicated algorithms, and will be a great contribution to an increase in convenience and popularity. In addition, this will save time and improve the accuracy for hand-counting. However, this study limited to aesthetic-visual part in biotop assessment. Therefore, it is certain that in the future research comprehensive assessment should be conducted with conservation and recreation view.
