The Daegu Metropolitan Transit Corporation Advisory Committee has chosen 5 styles of bridge-pier designs, including coating, graphic, planting, billboard and safety-facility style, based on the results of landscape simulations from a previous study. This study was conducted to investigate citizen's preferences and emotional images for each style of bridge-pier design, by aiming at the pilot urban landscape improvement section from Daebong Bridge in Suseong Gu to the crossroads near Dongseong Elementary School in Daegu Metropolitan City. The questionnaire was drawn up regarding the urban landscape improvement plans applied to the research area, and the questions were about citizens' perception of bridge-pier structures generated by constructing a light rail transit, important factors to consider when designing bridge piers, preferences for each style of bridge-pier design and emotional impact. 60.4% of the survey participants were found to perceive bridge-pier structures as unattractive, so it was necessary to improve them aesthetically. Regarding visual factors of bridge-pier designs, color was most important at 5.81, followed by form at 5.57. Regarding aesthetic component factors, harmony was most important at 6.07, followed by amenity at 6.00. In the survey participants' preference for each bridge-pier design, the graphic style was preferred most at 4.14, followed by the planting style. In emotional adjectives used for each bridge-pier design, the coating style, the safety-facility style and the non-treatment style showed similar results, and all of these styles were evaluated as artificial, lifeless and desolate. The graphic style and the billboard style showed different tendencies, depending on visual factors and aesthetic component factors applied to the graphic design used for these two bridge-pier styles. Since natural materials were used for the planting style, however, it showed high preference for such emotional images as natural and lively. The emotional adjective 'amiable' was found to affect citizens' preferences for each bridge-pier aesthetic improvement plan most, and it was also analyzed to have an effect on all the styles of bridge-pier designs. To improve the landscape of a light rail transit being constructed inside the urban area, this study quantitatively extracted citizens' preferences and emotional adjective for every style of bridge-pier design applied to the pilot urban landscape improvement section, and it is expected that the results of this study will be used as basic data to improve the landscape of bridge piers.

Urban railway are the most widely used means of transportation in the metropolitan area. It is difficult to draw out problems through the quantitative analysis technique because most of the research results show that most of the guide signs are installed with many or few guide signs. In this study, we propose a method to evaluate the information load and proper installation location at the main decision point in the transfer passageway for Suseo Station by applying Positive Guidance. As a result of analyzing the information load using this technique, it is suggested that the necessary information should be provided centered on the copper node because it provides confusion of the users by providing the same information in the transfer line. It is necessary to obtain guidance on how to remove the sign (advertising, high ceilings, etc). The study will be regarded as a key for the basis and placement of the guidelines for determining the appropriateness of the in the future urban railway station sign guide.

Korean economy has experienced rapid expansion of the service sector at the expense of the manufacturing sector since 1988, which was caused by the wage increase and the appreciation of Won. The government worried about the deindustrialization and the erosion of the international competitiveness, and various measures were taken to enduce labor force into the manufacturing sector. However, this article argues that the expansion of the service sector is inevitable phenomenon in the process of economic development, and the balanced industrial policies are desirable. In addition, the Uruguay Round Service Negotiations require liberalization of the service market and internationalization of the service industries.

This study examined the purchasing behavior and satisfaction of people with convenience store PB foods. The factors affecting the purchasing behavior and the overall satisfaction with the convenience store PB foods were examined. This study first found that the purchasing motivation of PB foods is the cheaper price than NB foods. Second, age is a statistically effective variable for the visit frequency at the convenience store and gender and age are effective variables for the purchase frequency of PB foods. Third, there is a statistically positive correlation of convenience store brand preference with the PB food brand preference for 6 food categories. Next, in terms of the attribute-level satisfaction, the most satisfied areas are diverse food groups and diverse food taste and the least satisfied areas is price. This is followed by taste and design/packaging influence overall satisfaction. From this analysis, the following suggestions were drawn. First, because consumers are likely to be matched convenience store brand preference and PB food brand preference, advertising is necessary to ensure that the consumers continue to visit the convenience store. Second, product improvement by increasing the quality should be designed to motivate the major consumer group of people in their 20s and 30s. Finally, to boost PB food satisfaction, the industry should improve the taste and design/packaging.

유역에서 상류 유역 또는 수변을 따라 자연 자원을 이용하여 조성되어야 할 완충지대는 비점오염의 영향을 줄이기 위한 중요한 최적 관리공법이다. 교란된 토지 피복과 수변 완충지대를 관리 및 복원할 때 같은 지형조건이라도 식생 종류, 발달정도, 토양조건에 따라 오염물 제거효과가 다를 수 있으며, 최소 완충지대 길이도 제거 오염물질 대상별로 적합하게 설계되고 해석되어야 한다. 본 연구의 목적은 용담댐 유역에서 SWAT 모델을 이용하여 식생 완충지대의 비점오염원 저감 모의 재현성을 평가하는 것이였다. 소유역의 관측값과 모델 예측값에 대한 모델의 검 보정이 선행되었으며 그 중에서 가장 높은 모델 효율을 가지는 소유역에서 three zone concept의 90m 수변완충지대를 지방하천을 경계로 하여 토지 피복도를 변화시켜 SWAT 모델에 적용하였다. 이 때 교목으로는 포플러 (Populus, 30m)을 적용하였고, 포플러의 높이 및 Leaf area index를 조정하여 관목 지대(30m)에 입력하였다. 잔디 지대(30m)는 자연초지를 선택하였다. 또한 지형변수(average slope)와 Manning's coefficient을 수변완충지대의 조건에 고려하여 변화를 주었고 이에 따른 유출량 및 유사량, T-N, T-P의 변화율을 조사하였다. 또한 5, 10, 30m의 식생 여과대를 밭 지역에만 적용하여 오염물의 저감 효율을 평가하였다. SWAT 모델은 각 소유역에서 발생된 전반적인 유출량과 수질변수의 추세를 잘 예측하였으며 정자천 소유역이 선택되었다. 모의된 완충지대에서는 연평균 940 m3/ha의 유출량이 감소되는 것으로 유사농도는 28.7 %의 저감효과를 보였다. 그러나 T-N, T-P의 농도는 오히려 증가되었는데 본 연구에서 고려된 보다 수변완충지대를 조성할 때 지하수 수위, 식생 성장변화 등과 같은 보다 정확한 설계 인자 산출 및 모델 DB 개발이 유역모델에 포함되어야 할 것으로 판단되었다.한 해결책을 얻어내는 상호보완적인 결과를 추구한다. 그가 디자인하는 작품은 전형적인 이미지를 내포하지 않는다. 즉 그의 작품은 기존의 가치와 이념적인 것은 배제하고, 창의적인 개념을 도출하였다.형모서리는 건물 특화 성격이 강하므로 불가피할 경우 소형 액센트 광고 위치를 미리 벽면으로 할애하는 것이 경관 및 입면계획에 유리한 것으로 분석되었다. 불확실도 해석모형 등의 새로운 기능을 추가하여 제시하였다. 모든 입출력자료는 프로젝트 단위별로 운영되어 data의 관리가 손쉽도록 하였으며 결과를 DB에 저장하여 다른 모형에서도 적용할 수 있도록 하였다. 그리고 HyGIS-HMS 및 HyGIS-RAS 모형에서 강우-유출-하도 수리해석-범람해석 등이 일괄되게 하나의 시스템 내에서 구현될 수 있도록 하였다. 따라서 HyGIS와 통합된 수리, 수문모형은 국내 하천 및 유역에 적합한 시스템으로서 향후 HydroInformatics 구현을 염두에 둔 특화된 국내 수자원 분야 소프트웨어의 개발에 기본 토대를 제공할 것으로 판단된다.았다. 또한 저자들의 임상병리학적 연구결과가 다른 문헌에서 보고된 소아 신증후군의 연구결과와 큰 차이를 보이지 않음을 알 수 있었다. 자극에 차이가 있지 않나 추측되며 이에 관한 추후 연구가 요망된다. 총대장통과시간의 단축은 결장 분절 모두에서 줄어들어 나타났으나 좌측결장 통과시간의 감소 및 이로 인한 이 부위의 통과시간 비율의 저하가 가장 주요하였다. 이러한 결과는 차가운 생수 섭취가 주로 결장 근위부를 자극하는 효과를 발휘하는 것이 아닌가 해석된다. 이와 같은 연구결과를 통해 생다시마를 주원료로 개발된 생다시마차와 생다시마 음료가 만성 기능성 변비 증세를 개선하는 효능이 잠재적으로 있음을 확인하였다. 그러나 생약제재의 변비약 수준으로 변비 개선 효능을 증대하기 위해서는 재료 배합비의 개선이나 대장 운동기능을 향상시키는 유효성분의 보강 등이 필요하다는 점도 알 수 있었다.더불어 산화물질 해독에 관

The street image in a business area is so much affected by Facade that the front side of a roadside building makes. Recently, for the indiscreet and intemperate advertising signboard of the front side of roadside buildings, a streetscape becomes more disordered than before, so now we need to do research about signboards of roadside buildings for a streetscape image. In this research, we focused on a streetscape with difference of occupation density of signboard in the business area via investigation and analysis about occupation density of signboards of the front side of roadside buildings, and we suggested optimum occupation density of signboards for supporting the road image positively. An object of research is the street in the business area that has many pedestrians and active passing zone of cars. We investigated and analyzed how to feel street images on the rate of occupation density of roadside building's signboards of in the chosen street. As a result of using an adjective that we use for estimating street view images for extraction of street images, we could know 2 factors. We named that one is the image of recognition, and the other is the image of feelings. We knew that signboard density of street of heavily recognized images is from 20% to 30% and, signboard density of street of heavily feeling images is from 50% to 60%. We also could know that people feel both images of recognition and images of feeling in specific density, 30 to 50%. Through this result of research, we can suggest Facade on signboard density with the recognition and the feeling and use images of the street view as materials to be more specific and more special.
