본 연구는 도시 간 상호작용 지수(지배력 지수, 상대적 강도 지수, 엔트로피 지수)를 활용하여 출근 흐름과 업무 흐름, 화물 흐름에 있어서 수도권 도시 네트워크의 구조적 특성을 분석하였다. 분석 결과는 수도권의 도시 네트워크가 흔히 네트워크형 도시체계론에서 말하는 수평적이고 상호보완적이며 양방향과 규모 중립적이기 보다는 매우 규모 의존적이고, 수직적이고 최고차 중심도시에 의존적하는 지배 종속적 구조를 가지고 있는 것으로 나타났다. 출근 업무 흐름에 비해 화물 흐름의 네트워크가 다소 균형적이기는 하지만, 상호작용의 계층 구조, 흐름의 상대적 강도, 균형성 등 모든 면에서 출근 업무 흐름이든, 화물 흐름이든 서울과의 상호작용이 결정적이다.

The objective of this research was an investigation of the important green spaces in Daegu and to present the basic frame of green network in Daegu. Present the condition of the significant green spaces is as follows: In the 3km radius of the city center, the isolation and discontinuation of the green spaces was extensive, caused by crowding of houses and funeral parlours. Consequently, the isolation relaxation which leads to the additional creation of the green spaces and a buffering plan were demanded. In the transfer area of a 3∼6km radius, which is located between the city center's congested area and the suburb green spaces, the significant green spaces had high connection and buffering characteristic, but in the northwest and the south, serious discontinuation appeared between the suburb green spaces and the city conte green spaces. In the 6∼9km radius, the suburb important green spaces accomplished the function which extended the back core green spaces to the city center area. But creation of buffering green spaces was necessary in part because of proximity to the resident area. The results suggest a connection between green spaces on the base of the distribution of the important green spaces, were as follows: In the 3km radius, irregular direction lines appeared while a schedule one direction line appeared in 3∼6km and 6∼9km radius. The discontinued parts of the green network were caused by industrial complexes, house crowding, and cultivation areas. Consequently, reservation and creation plans of green spaces in response to this were demanded. Through the additional creation of green spaces in the discontinued parts, the basic frame of green network in Daegu was the radiation annular form. And it was suitable to activate the parks and the general green spaces.

The purpose of this study was to assess and evaluate salty taste preferences. Samples for the salty taste test were made by adding sodium chloride to soybean sprout soup at five different concentrations: 0.08% (unsalty) ; 0.16% (slightly unsalty) ; 0.31% (neither unsalty nor salty) ; 0.63% (slightly salty) ; and 1.25% (salty). Over 4,210 subjects were randomly selected and tested over a three-year period from 2005 to 2007 in Daegu. The results of the taste test were as follows: Forty-five percent of the subjects preferred soup with a salty taste and slightly salty taste. Most subjects preferred soup with a 0.31% concentration of sodium chloride. There were positive relationships between intensity and preference in 0.08%, 0.16%, and 0.31% concentrations, but there were negative relationships between intensity and preference in 0.63% and 1.25% concentrations (p<0.01). Upon examining a relationship between the taste assessment results and salty eating attitude scores, it was found that the subjects who preferred slightly salty and salty taste showed higher total scores in terms of habitual preference for/enjoyment of eating salty foods than the other groups. Comparing the taste test results with the subjects' stated preference, it was found that 70.3% of the subjects who were classified as preferring salty taste recognized this preference and 53.3% of the subjects who were classified into the population than tends to eat slightly salty food responded that they also tend to prefer a salty taste. Based on these results, this salty taste assessment study can be used as a practical and useful nutrition education tool for assessing and possibly reducing salt intake.

The purpose of this study was to develop a nutrition education program for dietary salt reduction using various nutrition education materials. The effect of a 5-week nutrition education program on salty taste assessment, nutrition knowledge, salt attitude for a high-salt diet, salt content in food, and individual satisfaction with the salt concentration of meals during the education period was evaluated. Nutrition education materials included two animations, a pamphlet, panels, and a website, as well as other training resources. Subjects participating in this study were 335 employees (164 male, 171 female) at 15 foodservice operations in Daegu. Preference for higher levels of salty taste and food containing higher amounts of salt were lowered. Knowledge regarding the necessity for dietary salt reduction was higher (p < 0.001) than before nutrition education, and salt content in a meal was reduced. As the program progressed, average salt concentrations of soups were significantly lowered (p < 0.05), and there was greater satisfaction with the lower concentration (p < 0.001). This was a positive indication of the program's success. In addition, it was found that subjects who participated in the program several times have changed their preference to lower levels of salty taste and have increased their nutrition knowledge (p < 0.05, p < 0.001). Thus, the positive effect of this 5-week nutrition education program developed for, and applied to, foodservice employees, concerning dietary salt reduction was confirmed.

One of the most important elements in creating the pleasant residential environment is the wind. For the pleasant residential environment, it is important that the air pollutants are not stagnant but appropriately and swiftly diffused and removed by winds. Especially, the river becomes a main route of wind in the urban core. So, it is necessary to secure the space to circulate the sufficient cool air to this area. But, recently many high-rise apartment complexes have been built along the rivers that have the fine view and pleasant environment. As a result, the cool and fresh air coming from mountains hardly diffuses into the urban core but just flows along the river. Considering the facts above, this study selected types of building layout and kind of land cover as complex or architectural design factors that have an influence on wind environment. Based on the factors, it analyzed change in wind environment according to apartment complex development aiming at the Sinchun area which is Daegu Metropolitan City's main wind corridor. Therefore, when apartment complex development is planned in the future, it can offer basic data for establishing plans for more pleasant complexes. As a result of the analysis, it was shown that the layout type of housing and the building height plan in consideration of wind corridor around the river were pretty effective in increasing the wind speed and circulating the air in the apartment complex. Therefore, if wind corridor is considered when apartment complex development is planed in the future, this study can offer useful information contributing to improve comfort in residential environment in the level of complex building as well as city planning.

Today, the need for alternative energy has increased due to the global environmental problems and energy depletion. In order to solve a global environmental matter and an energy issue simultaneously, the application of the renewable energies in building has been constantly demanded. therefore, we must develop new energy resources that are abundant and provide substitutes for fossil fuels and we must study the application method of the renewable energies in building. Among renewable energies, the solar energy(photovoltaic system) is clean, inexhaustible, and available everywhere in the world and is judged to have the application possibility in building. Daegu city has a plan of putting a photovoltaic system on large buildings. For instance, EXCO, exhibition and convention building, and dormitory in Kyungpook National University, Dongho elementary school, Osan building in Keimyung University, Young korea academy in Daegu, are on the process of having a photovoltaic system. Therefore a study on the performance of photovoltaic system is important for the system design and maintenance. this paper describes the first invest cost, and performance test of the 95kW utility-interactive photovoltaic power system.
