This study ultimately aims at suggesting the improvements for community development policy in Korea. In order to do so, this carried out field surveys for two rural villages and tried to find out the current institutional situation of rural villages. Reviewing conceptual debates on rural, village, community and organisation theory, it sets up a typology of four groups as follows: voluntary expressive group, involuntary expressive group, voluntary instrumental group, and involuntary instrumental group. Based on this typology, this study conducted field surveys for two rural villages; Pyeongchon-Ri in Chungnam and Noolmi-Ri in Kyoungbuk. From the analysis on the field surveys, it finds some features on Korean rural groups. First, the residents in rural villages have very strong identity for their living areas. Second, the number of rural groups are tend to decrease recently. Third, the actions of instrumental groups are determined by the organisations operating nearby. Fourth, the function of groups within rural villages only carry out some village festivals, but other friendly relationship among rural residents are expanded out to wider areas called Myeon. As a result, this study suggests that we should recognize the diversity in rural communities in Korea and deals with them in different ways of public policies.

경북 봉화군 소천면의 선캠브리아기 변성퇴적암 내에는 석회규산염층이 산출되며, 이 석회규산염층은 두께 14~18 m 정도로 층리면에 평행하게 협재되어 있다. 이 암층에는 방해석, 백운석, 사문석, 투각섬석이 주로 포함되고, 일부에서 활석이 소량 포함된다. 사문석은 석회규산염층의 중상부에 다량 함유되고 투각섬석은 하부층에서 주로 산출한다. 사문석이 많이 포함된 암석일수록 짙은 녹색을 나타낸다. XRD 및 FT-IR의 분석결과, 이곳의 사문석광물은 안티고라이트에 해당하는 것으로 나타났으며, SEM의 관찰에서도 안티고라이트의 판상 형태가 잘 나타났다. EPMA에 의한 이 사문석의 성분 분석의 결과, 안티고라이트의 이상적인 조성(SiO2: 44.3 wt% and MgO: 40.8 wt%)에 가깝게 나타났으며, 이를 통하여 계산된 구조식은 Mg2.82Al0.04Fe3+0.04Si2.05O5(OH)4으로 나타났다. 석회규산염층은 구성 광물 및 산상 등을 검토해 본 결과, 퇴적 당시 환경에 따른 퇴적물의 광물 및 화학성분의 차이를 가지는 석회질 퇴적암이 변성작용을 받아 형성된 것으로 보인다. 안티고라이트가 다량 함유되는 상부층은 투각섬석이 포함되는 하부층에 비해 상대적으로 Mg이 더 풍부한 퇴적암으로 구성되었을 것으로 사료된다.

경북 봉화지역의 선캠브리아기 홍제사 화강암 내에는 견운모 광상이 분포한다. 이 지역의 대현광산과 성황광산에서 산출되는 견운모에 대하여 현미경 관찰, X-선회절분석, 전자현미분석, X-선형광분석, ICP분석 등을 통하여 지화학적 및 광물학적 특성을 조사하고 그 형성과정을 검토하였다. 이 지역 견운모광상은 열수변질작용에 의해 화강암을 모암으로 한 견운모화작용에 의해 형성되었다. 이곳에 나타나는 광물조합과 그 산출상태로부터 4가지치 변질대로 구분되었다. 이러한 변질대는 점이적인 열수변질작용에 의해 형성된 것으로 나타났다. 이곳에서 산출하는 견운모는 광물화학적으로 모두 일라이트에 해당되는 것으로 나타났으며, 다구조형도 모두 2M1으로 매우 단순한 형태를 보였다. 거의 순수한 견운모 광석은 여러 색을 나타냈으나, 주화학성분이나, 결정구조에서의 차이는 나타나지 않았다. 미량성분을 검토한 결과 진한 녹색을 띠는 것은 Cr이 상대적으로 다량 함유되고, 흑색의 것은 Ti이 상대적으로 많은 것으로 나타났다. 모암인 홍제사 화강암내에서 견운모 광상이 발달하는 것은 단층과 같은 단열구조와 관련되는 것으로 나타났다. 엽납석 및 고령석 등의 다른 변질광물은 나타나지 않으며, 열극대를 따라 변질된 단순한 형태의 열수광상인 것으로 나타났다.

Producing Korean organic beef cattle costs a great deal because it needs breeding conditions like the organic feed, an uncontaminated breeding farm and so on. So the price of Korean organic beef (KOB) is more expensive than that of Korean general beef (KGB). To overcome this adverse price condition, a case production organization in Asan will choose direct marketing routes for consumers or the shop under direct management of the organization, or franchise shops. As a result, these marketing routes are expected to narrow the price gap between KOB and KGB. And consumers will accept the price of KOB if quality of KOB is very high level, for example the first grade++.

Groundwater recharge characteristics in a fractured granite area, Mt. Geumjeong, Korea. was interpreted using bedrock groundwater and wet-land water data. Time series analysis using autocorreclation, cross-correlation and spectral density was conducted for characterizing water level variation and recharge rate in low water and high water seasons. Autocorrelation analysis using water levels resulted in short delay time with weak linearity and memory. Cross-correlation function from cross-correlation analysis was lower in the low water season than the high water season for the bedrock groundwater. The result of water level decline analysis identified groundwater recharge rate of about 11% in the study area.

Aquatic and riparian vegetation of river ecosystems are very important both in ecological and management perspectives. Vegetation surveys were conducted to understand the characteristics of riparian vegetation in the mid and lower reaches of the Nakdong River, Korea. A total of 68 families and 260 species were identified at eleven survey sites. The numbers of taxa were similar to those reported in a previous survey in 1996,but the percentage of naturalized plants increased more than two times compared to that in the previous survey. Survey sites near Yangsan Bridge and Nambu Park in Yangsan showed the highest percentage of naturalized plant species. Urbanization indices of the survey sites were high at 18.8% on average. Therophytes were the most dominant plant life form at the survey sites with 39.2% of total plants identified, followed by phanerophytes (19.2%), hemicryptophytes (18.9%), aquatic plants (13.9%), cryptophytes (5.8%), and chamaephytes (3.1%). The relative composition of hemicryptophytes decreased whereas those of therophytes and chamaephytes increased compared to those in the survey in 1996. This may be due to increase in dryness of riparian soils or degradation of riparian areas. Plant compositions at sites near Jeokpo Bridge and Hwoicheon suggest that the composition and distribution of riparian vegetation are affected by land use pattern surrounding riparian areas or human accessibility to the areas.

The frequency analysis and the probability plot were applied to heavy metal contents of soils collected from the Goseong Cu mine area as a statistic method for the determination of the threshold value which was able to partition a population comprising largely dispersed heavy metal contents into the background and the anomalous populations. Almost all the heavy metal contents of soil showed a positively skewed distributions and their cumulative percentage frequencies plotted as a curved lines on logarithmic probability plot which represent a mixture of two or more overlapping populations. Total Cu, Pb and Cd data and extractable Cu and Pb data could be partitioned into background and anomalous populations by using the inflection in each curve. The others showed a normally distributed population or an largely overlapped populations. The threshold values obtained from replotted frequency distributions with the partitioned populations were Cu 400 mg/kg, Pb 450 mg/kg and Cd 3.5 mg/kg in total contents and Cu 40 mg/kg and Pb 12 mg/kg in extractable contents, respectively. The thresholds for total contents are much higher than the tolerable level of soil pollution proposed by Kloke(Cu 100 mg/kg, Pb 100 mg/kg, Cd 3 mg/kg), but those for extractable contents are not exceeded the worrying level of soil pollution proposed by Ministry of Environment(Cu 50 mg/kg, Pb 100 mg/kg). When the threshold values were used as the criteria of soil pollution in the study area, 9～19% of investigated soil population was in polluted level. The spatial distributions of heavy metal contents greater than threshold values showed that polluted soils with heavy metals are restricted within the mountain soils in the vicinity of abandoned mines.

Heavy metal concentrations in the soil were investigated for the abandoned Samkwang metal mine, Cheongyang-Gun, Chungnam Province, Korea. The concentrations of heavy metal(As, Cd, Cu, Ni, Pb, Zn) were determined in mine soils collected at the abandoned mine sites to obtain a general classification and specification of the pollution in this highly polluted region. The results estimated with the normal test and basis statistic on the central tendency and variation showed that the distribution of heavy metal concentration had significantly different at the range of all locations. The range of spatial distribution on the relationship of heavy metal concentration and pH was 4.8∼8.8 and heavy metal concentration on the type of land use was highest in forest land, and also Ni and Zn in farm and rice field showed the high concentration. The distribution of heavy metal concentration on the depth of a soil showed that the metal concentrations in subsoil were higher than of those in surface soil, while the concentration of Cu and Ni had no significant difference on the depth of soil. Results from the correlation analysis using the data except the extreme and unusual data revel that Zn-Cd(r=0.867), Zn-As(r=0.797), Zn-Pb (r=0.764), Cu-Cd(r=0.673), Cu-As(r=0.614) and Zn-Ni(r=0.605) were the most important parameters in assessing variations of heavy metal in soil. To discriminate pattern differences and similarities among samples, principal factor analysis(PFA) and cluster analysis(CF) were performed using a correlation matrix. This study suggests that PFA and CF techniques are useful tools for identification of important heavy metal and parameters. This study presents the necessity and usefulness of multivariate statistical assessment of complex databases in order to get better information about the quality of soil and gives the basis information to clean up the abandoned mine sites.

This study summarizes the relations among PM2.5 concentration, water-soluble ions concentration, metallic element Components characteristics and SPSS in negative ion and metallic element of PM2.5 particle in Miryang.(By the urban area, the industrial complex area and the suburban area according to the season) PM2.5 concentration of total 72 samples collected from 3 sites turned out to range from 3.47 to 34.7 μg/m3 , and the average concentration was the suburban area-the kin nup(16.00 μg/m3 ) > the urban area-the roof of the old Miryang university(10.32 μg/m3 ) > the industrial complex-Sapo industrial complex(10.29 μg/m3 ). In particular, the suburban area had PM2.5 concentration 1.5 times those of urban area, industrial complex. It was thought although the site was suburban and farm-side without pollutants around, it had a higher concentration value influenced by external factors including the brickyard, small-scale incinerator, driving range construction, construction on the Daegu-Busan express and the widening of the four-lane road between Miryang-Anyang nearby. As for water-soluble ions among PM2.5 particle collected in Miryang area, SO42− accounted for 60% and NO3−, was 30% in spring and summer. And NO3− accounted for 50% and SO42− was 35% in fall and winter. The AI value of metallic Components among PM2.5 particle collected in Miryang area had a high value influenced by the apartment complex construction and the extension work of road. The industrial complex area had Zn concentration 3 times, and Fe concentration 2 times those of urban area and suburb area. When it comes to the relation with metallic elements in urban area, the highest coefficient of correlation was between Cr-Fe with 0.85, and Pb-Cd turned out in the reverse correlation. Among metallic elements, the coefficients of correlation between Zn and Cr, Mn, Fe, NI were high in industrial complex area. The highest coefficient of correlation was between Mn-Zn with 0.88, meanwhile Ni and Cu, Cd turned out in the reverse correlation in the suburb area. These coefficients of correlation are attributed to the difference in pollutant sources, rather than difference in pollutant and non-pollutant.

According to the survey, having access to a green environment in hospital building acts as an attractive element when visiting an obstetrics & gynecologist hospital. People want an open space where they can experience landscape-like features, even though they are faced with such limiting circumstances. A variety of conditions have to be met in order to compose a good indoor landscape design, from variety in plant selection, to flowers with great scents. In order to attract more patients, investment in creating an attractive indoor landscape will soon become a requisite for all medical facilities and local clinics that are to be built.

In an effort to interpret the characteristics of fine particle concentrations in Busan, time variations of hourly monitored concentrations PM10 (Particulate Matter with aerodynamic Diameter ≤10 ㎛) in Busan are analyzed for the period from 2000 to 2005. The characteristics of aerosol second generation formation process is also interpreted qualitatively, by using the statistical analysis of the meteorological variables including temperature, wind speed, and relative humidity. The result shows some significant annual, seasonal, weekly and diurnal variations of PM10 concentrations. In particular, seasonal(i.e., spring) variations are governed by frequency of yellow sand events even for the non-yellow sand cases where yellow-sand days are eliminated in our analysis. However, in seasonal variation, summer season predominate lower PM10 concentrations due to the frequent precipitation, and weekly and diurnal variations are both found to be reflecting the emission rate from traffic amount. Correlation coefficients between PM10 concentration and meterological variables for non-yellow sand days show overall negative correlation with visibility, wind speed, cloud amounts, and relative humidity. However for non-precipitation days, during non-yellow sand period positive correlation are found clearly with relative humidity, suggesting the importance of secondary aerosol formation in Busan that can be achieved by both homogeneous aerosol formation and heterogeneous transformations resulting from hygroscopic aerosol characteristics.

현재 중국의 경우 산업발전은 매우 빠르게 이루어지고 있으나 아직까지 인프라 시설이 구비되어 있지 않아 수요와 공급의 불균형을 이루고 있다. 그러므로 중국자체로는 매년 넘쳐나는 미주 또는 구주 발 총국동북부 지역의 항공물동량을 모두 처리하기 어려운 실정이며 이는 우리나라가 해공복합운송 거점으로서 위상을 확립할 수 있는 좋은 기회가 될 것이다. 이에 본 연구에서는 해공복합운송과 항공운송의 노선별 시뮬레이션 평가를 통해 경쟁력 수준을 평가하고 향후 화물유치를 위한 나아가야 할 방향 등을 제시하였다. 첫째 향후 해공복합운송의 물량을 확보하기 위해서는 지리적으로 유리할 뿐만 아니라 본 연구의 시뮬레이션 분석에서도 도출되었듯이 중국발 미주착 부분에 더욱 집중적으로 관심을 가지고 비즈니스 모델을 창출하여야 할 것이다. 둘째, 해공복합운송의 주요 요인은 비용보다도 서비스에 의한 인지도 부분이나 전체적으로 걸리는 시간에 의하여 결정되는 것으로 나타났으므로 고객의 니즈에 맞는 서비스를 개발하고 이를 지속적으로 제공하여 해공복합운송에 대한 인지도 향상과 아울러 현재 추진 중인 청도와의 RFS(Road Feeder Service)시스템을 주요 해공복합운송의 출발항인 상해, 위해, 연태지역으로 확대하여 추진할 필요가 있을 것이다.
