        The purpose of this study was to analyze the village groves in Pohang city by classifying them into 5 categories: sage plantation, shelter-belt plantation, shore plantation, ornamental plantation and bower plantation. The results of this study can be summarized as follows; The village groves in Pohang city consist of 16 sage plantations (128,682㎡), 14 shelter-belt plantations (807,755㎡), 17 shore plantations (447,616㎡), 10 ornamental plantations (141,276㎡) and 6 bower plantations (79,075㎡). Namely, the ratio of shore plantations is highest (n=17) in terms of number, while that of shelter-belt plantations is highest (50.3%) in terms of area. On the other hand, Pinus Thunbergii account for the absolute majority (n=55,239, 74.1%) of the trees, followed by pine trees (n=18,017, 24.2%). Both species are combined to account for 98.3% of the entire trees, which means that the plantations are simple in terms of tree species. When the village groves were compared in terms of functional age, sage plantations are oldest or aged 143 years, followed by bower plantations (aged 137), ornamental plantations (aged 118), shore plantations (aged 92) and shelter-belt plantations (aged 88).

        A survey of middle school students and teachers in Mokpo city has been done to understand the perception of environment of students and the present situation of environmental education in middle school. Only 2 of the 14 middle schools have chosen the environmental education course as a required subject. The majority of middle-school students in Mokpo city have learned the environmental education as a subordinate course included in the other subjects such as science, social science or technology. The environmental education in school has been done mostly through non-subject activities such as club activity, group work etc. The survey shows that almost all students think the environmental pollution is serious problem(83% of respondents) and they are especially interested in separate garbage collection(72%) and environmental conservation activity(63.9%) to protect the environment. The concerns about the environmental problems of students(57.7%) has increased after environmental education regardless educational methods or subjects. The students and teachers think that environmental education in school has not been carried out enough and almost all of them(68.4% of students, 97.5% of teachers) agree that the environmental education should be done as an independent subject. In order to more practical and effective environmental education, many opportunities to experience environmental conservation activities should be given during the environmental education course and the environmental education should be separated from other subjects to be taught independently. Moreover, it might be necessary to increase proportion of teachers in environmental disciplines and to develop various teaching methods.

        Sixteen soil samples around six areas (residental area, traffic area, power plant area, incineration area and factory area) where the stationary and mobile sources of polycyclic aromatic hydrocarbons (PAHs) are estimated to be emitted in Jeju City, were collected during Feburuary to March, 2004, and analyzed for 16 PAHs recommended by US EPA as primary pollutants to investigate their distribution characteristics. The concentrations of total PAHs (t-PAHs) and total carcinogenic PAHs (t−PAHCARC) in soils of Jeju City were in the range of 21.7∼264.2ng/g on a dry weight basis with a mean value of 87.2 ng/g and 6.3∼118.0ng/g with a mean value of 33.4 ng/g, respectively. The concentrations of t-PAHs were low in comparison with those in soils of other domestic and foreign countries. The mean concentrations of t-PAHs and (t−PAHCARC) with area decreased in the following sequences: traffic area> incineration area > factory area > power generation area > harbor area enli residental area. The correlation between t-PAHs and (t−PAHCARC) were very high (γ2=0.9701), indicating that (t−PAHCARC) concentration increases in proportion with t-PAHs. Comparing the distribution ratio of ring PAHs with area among 16 PAHs, it decreased in the order of 4-ring > 5-ring > 6-ring > 3-ring > 2-ring in all the areas except for harbor area. whitens for harbor area it was similar among 3-, 4- and 5-ring with high value. Low and no correlations between t-PAHs and soil compositions (organic matter content and particle size distribution) were observed, which is considered to be caused by the complex factors, such as the loading and characteristics of PAHs and diverse soil environment change, etc. From the examination of the three PAH origin indices, such as LMW/HMW (low molecular weight 2∼3 ring PAHs over high molecular weight 4∼6 ring PAHs), phenanthrene/anthracene ratio and fluoranthene/pyrene ratio, it can be concluded that the soil PAH contaminations were ascribed to strong pyrogenic origin in ail areas except for harbor area and to both pyrogenic and petrogenic origins.

        The runoff characteristics of non-point source pollutions in the municipal area of Jeonju were investigated and analyzed by using the SWMM (Storm Water Management Model). The flow rates and water qualities of runoff from two types of drainage conduits were measured respectively. One was a conventional combined sewer system and the other was a separated sewer system constructed recently. From August to November in 2004, investigations on two rainfall events were performed and flow rate, pH, BOD, COD, SS, T-N and T-P were measured. These data were also used for model calibration. On the basis of the measured data and the simulation results by SWMM, it is reported that 80-90% of pollution load is discharged in the early-stage storm runoff. Therefore, initial 10-30 mm of rainfall should be controlled effectively for the optimal treatment of non-point source pollution in urban area. Also, it was shown that the SWMM model was suitable for the management of non-point source pollution in the urban area and for the analysis of runoff characteristics of pollutant loads.

        This design proposal was made for the school forest plan of Samdeok Primary School and which goals were to realize the programs of making the school forest and removing the school wall. The results of developing programs could enhance the existing conditions of the school from the primary educational state to the sustain-able and friendly nature state.The site is located at 361 Samdeok-3ga, Jung-gu, Daegu and which is about 15,150㎡ and divided into 2 parts of design site of 150m in length, 15m in width respectively. The client suggested some guidelines to develop spaces of environmentally and educationally-friendliness without reducing athletic area. The design concepts are divided into 4 thematic activities such as Open Education, Outdoor Music Activity, Ecological Educational Activity and Social Interrelated Activity. The master plan has two seperated areas which are the main gate area and the back side of the school. The basic plan of the main gate area is characterized by the school forest which has Pine Tree Forest, Rock Shelter, Forest with Pictures and Books, Wild Flower Bed, Gravel Road, Outdoor Music Theater, Forest with Poets and Music, Monumental Sculptures. The back side area has also many various design components such as Decorated Seating Wall with Tree Shades and Bird Nests, Street Mini Park, Small Pond, Shaded Trees and Hedges. This project was constructed from May to June, 2005 as the first year budget of the school. But the limited budget cut down and reduced many parts of the whole design and that is the main problem of this project. The school could solve this problem gaining many kinds of funds from the various sources such as Deagu Metropolitan Office of Education and The P.T.A etc.

        Even if people living well-being need more green space and green experience in urban area, there is not enough open space like trees and forests. It may be caused by which the image elements of city are focalized only on physical elements like buildings, structures, etc. since Lynch's 'the image of the city'. This study tries to create new green image elements instead of the physical city image elements of Lynch style. For making new green elements it is used symbol, image, and meaning of trees abtained from results of reviewing in arts, music, religion, literature, myth, etc. The 5 new green image elements are water, isolated trees, green corridors, forests, and forest cultural event. Water is origin of all green lives, isolated trees are natural monuments(trees) and big trees, green corridors are street trees and green way, forests are woodland in city, parks, and village forests, and forest cultural event is events related to forest culture.

        Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were investigated in soil and pine needle samples taken from 16 sites of industrial and residential areas in Changwon, Korea to assess their distribution levels and to suggest the influence of industrial activities. PCDDs/DFs levels in the soil samples ranged from 0.57 to 20.79 pg I-TEQ/g dry weight with a mean value of 4.20 pg I-TEQ/g dry weight. PCDDs/DFs levels in the pine needle samples ranged from 0.39 to 8.75 pg I-TEQ/g dry weight with a mean value of 4.09 pg I-TEQ/g dry weight. In both soil and pine needle samples, the PCDDs/DFs concentrations in the industrial area sites were higher than those in the residential area sites. Homologue profiles in pine needle samples showed different patterns compared with soil samples. Based on the results of principal component analysis (PCA), it was confirmed that pine needles reflected a direct influence from local potential sources of PCDDs/DFs, showing a much higher degree of reflection than in soils. Pine needles are very useful as an indicator for monitoring or estimating the contamination of PCDDs/DFs in other areas which have been impacted by point pollution sources.

        Samples of water, soil, and sediment were taken from 10 streams of Andong city in Gyeongbuk province in October 2004. To assess the degree of environmental pollution for each stream site, the chemical analyses of pollutants such as T-N, T-P, COD, heavy metal, organophosphorous and organochlorine pesticides, and dioxin-like PCB congeners were implemented using the standard process tests or the U. S. EPA methods. In addition, biological assessment using insect immune biomarkers was conducted on the same environmental samples to complement the chemical assessment. Except Waya stream (T-N; 2.91 mg/L, T-P; 0.16 mg/L, COD; 14.0 mg/L) with above the environmental quality standards, the T-P and COD concentrations of 9 sites are relatively low. The contents of Pb and Cd in samples taken from each stream were much lower than environmental quality standards. However, in comparison with soil samples of other streams, several times higher concentrations of Pb and Cd were found in locations at Mi, Gilan, Yeonha, and Waya stream sites. Dementon-S-methyl, diazinon, parathion, and phenthoate compounds among organophosphorous pesticides were detected as concentrations of ppb levels, respectively, from soil samples collected in the vicinity of Gilan, Mi, Norim, and Waya stream. On the other hand, 16 organochlorine pesticides and 12 dioxin-like PCB congeners selected in this study were not found in all samples. In particular, considering significant disrupting effects of Waya stream's samples on insect immune capacity, this stream seems to be contaminated with investigated and/or uninvestigated pollutants in this study.

        Pick-up/delivery of consumer goods to offices, shops, and restaurants in order to support urban lives is one of the most vital activities in a city. With economic growth and technological innovation, a greater variety of goods have come to be supplied, and pick-up/delivery of consumer goods has become more complex. Efficient urban goods movement in Central Business District(CBD} starts with an efficient system for loading/unloading, and pick-up/delivery activities. Loading/unloading activity may be carried out on-street, or on especially designated space inside or outside buildings. Therefore, purpose of this study is to clarity the efficient urban goods movement in CBD(also called the pick-up/delivery activity) from the three different types of loading/unloading facilities. For this purpose, the differences in loading/unloading and truck-trip activity time of each loading/unloading facility was compared by performing the simulation analysis.

        Atmospheric particulate matters were collected by 8-stage non viable cascade impactor from October 2002 to August at Jeju City. Eight water-soluble ionic components (Na+, NH4+, K+, Ca2+, Mg2+, Cl-, NO3- and SO42-) were analyzed by Ion Chromatography. The concentration of particulate matters and eight water-soluble ionic components were determined to investigate their size distributions. Particulate matters exhibited a tri-modal distribution with peak value around 0.9, 4.0㎛ and 9.5㎛. In summer, the last peak value was lower than other season values likely due to particulate matter scavenged by rain water. Four ionic components (Na+, Ca2+, Mg2+ and Cl-) exhibited a bi-modal distribution in the coarse mode whereas three ionic components (NH4+, K+ and SO42-) in the fine mode, with maximum peak value around 0.9㎛. NO3- was found in both the coarse and the fine mode. The enrichment factor (E.F.) of each ionic components was calculated. Based upon E.F., it is considered that Na+, Cl-, and K+ in coarse paricle mode were delivered form oceanic source, but other components might have other source origins.

        The main objectives of this research are to analyse and evaluate the demolishing walls initiative in Daegu city as the collaborative urban environment improvement initiative in South Korea using the actor network theory concept. Local authorities are unable to effectively and efficiently improve urban environment because of their limited statutory and financial powers. This inability crucially led to the formation of the demolishing walls initiative in Daegu city with building a coalition of the local people, interest groups and public and non-governmental organisations in the operational processes in order to improve the physical and social urban environments. Furthermore, co-ordination between local authorities and landscape architecture specialists not only to change the way in which they tackle urban environmental problems but also to make the local people aware of their potential ability in positively improving the urban environment.

        As urbanization has been expanded in Korea, open spaces, such as urban parks and public sites, have been utilized for other uses, and then this bring out environmental changes for the worse. It is expected that these changes become more serious problems due to overpopulation, increasing individualism, and development of transportation. This research base on the consideration of connecting between decreasing urban green spaces and distributed green sites so as to build the substantial plan for the Green Network construction for urban heat island mitigation in Dalseo district, Daegu Metropolitan City. The result were as follow; 1)Connecting existing natural sites to the remained parks green zone made an Ideal form of Green-Network system. 2)Some school sites were selected for usable open spaces in order to build Green-Network system, and the plan connecting together with exist natural sites was suggested. 3)Moreover, the scheme of planting on the road spaces for connecting green spaces was proposed. 4)The devices of planting on the urban riverside for enhancing the role of urban stream to form green network was conceived.

        In this research, we have performed a T-test to see how the relationship between dependent variable or visual point level and independent variable or visual quantity is in order to clear up the correlation between pattern of visual point and visual quantity by the constituents of a view from a different visual point level and the results are as follows: 1) In case of the character of Mt.Uam landscape of the city, Uamsan is set as a fixed point and about a direction of view(D), the north is a datum point from which the range of direction is distributed within 180° westwardly and the visual range(R) is also within 2000m. An elevation is an average of 7.4° and the average story of the buildings is 3.85. Here the height of a story is about 4m so the average of the visual point difference is estimated at 15.4m. 2) The type of visual point is divided into the intersection group and the front of the highly used public buildings group. Double intersection types account for about 78.8%(52 spots) which forms a majority part of LCP. 3) The analysis of the difference of visual point level divided by eye level and that of the top of the buildings has been proved that there's a sharp difference resulted from t-test at 1% significant level. The significant difference of elevation from height difference(15.93m), however, has not been shown. 4) From the result of T-test about visual quantity by the elements of a view from a different visual point level, the visual quantity of mountain(VQM), sky(VQS), ground(VQG) is significant at about 1% each and that of building(VQB) is at about 5%. The difference in visual quantity of a mountain by the visual point level is at about 4% which can meet a marginal level of LCP necessary for evaluation of mountainscape.

        To identify the characteristics of wastewater flow generated in treatment basins of Seogwipo-city, we selected 3 stations representing the basin and performed 7 times of field survey including 5 times in dry periods and 2 times in wet periods from Feb. 25 to May 27, 2002 for the selected stations. From the analysis of flow data measured for more than 60 days in the interval of 5 minutes and concentration data obtained from laboratory analysis, we can draw several conclusions. First, in the analysis of diumal variation of wastewater flow for land-use types, we could find the following results: in the residential area, it is observed that wastewater flow rates rise early in the morning for the office-going hour and fall gradually and rise again after the office-leaving hour, showing typical residential wastewater flow pattern, while for the residential and commercial area flow rates rise early in the morning at the office-going hour and move up and down repeatedly within wide range and last till the office-leaving hour, which can be resulted from wastewater that is generated by tourists activated after early in the afternoon, while for the touristy area flow rates rise early in the morning and fall gradually and rise again within wide range. Second, in the analysis of temporal variation of wastewater flow for monthly, it can be observed that in the residential area, in the residential and commercial areas the flow rate of May is higher than that of Feb., March, while for the touristy area flow rate is without monthly because it reflects the movement of population, Third, in wet periods concentration of water-quality item such as SS, BOD, and CODCr is high in the beginning of rainfall by first flush, and falls down gradually to reach the steady state, which is the level of wastewater in dry periods after the cease of storm water due to diluting effect resulting from additional runoff water through storm sewers.

        The purpose of this study is to investigate an epistemological recognition of rural society. This study suggests an epistemological reorientation for rural society circumscribing diverse theoretical thoughts as well as empirical evidences. Traditional theoretical perspectives in urban-rural dichotomy envisioned by modernistic idea have regarded rural society as a premodern and underdeveloped society. The perspectives also have regarded city as a symbol of civilization and development. These perspectives thought of the function of rural society as a periphery that can survive as a back-up for urban-oriented prosperity. This study shows that these idea have been concentrated on agricultural expansionism and productivism which do not function in the post-modem societies my longer. The present study argues that these modernistic idea give little understanding of implicit value of rural society. Owing to the functional change of rural society which is quite omnipresent in the 21'st centuries in the world, the present study argues that the value of rural society should work even in the market society that has traditionally been regarded as an working-mechanism in urban society. The present study drives a new insight showing that rural renaissance is an explicit existence instead of a phenomenal one.
