The primary countermeasure for environmental stresses of crops grown in Korea would be to maintain top soil content of available B for upland crops and Si for low land rice in balance with other nutrient elements such as N, P and K, so as to maintain those nutrient balances in plants. Development of standard levels of elements in soils for balances uptake of those elements by plants are needed under the multi nutrient factor balance concept using the soil test results.

It is important to analyze the seasonal change profiles of land cover type in large scale for establishing preservation strategy and environmental monitoring. Because the NOAA-AVHRR data sets provide global data with high temporal resolution, it is suitable for the land cover classification of the large area. The objectives of this study were to classify land cover of Korea, to investigate the phenological profiles of land cover. The NOAA-AVHRR data from Jan. 1998 to Dec. 1998 were received by Korea Ocean Research & Development Institute(KORDI) and were used for this study. The NDVI data were produced from this data. And monthly maximum value composite data were made for reducing cloud effect and temporal classification. And the data were classified using the method of supervised classification. To label the land cover classes, they were classified again using generalized vegetation map and Landsat-TM classified image. And the profiles of each class was analyzed according to each month. Results of this study can be summarized as follows. First, it was verified that the use of vegetation map and TM classified map was available to obtain the temporal class labeling with NOAA-AVHRR. Second, phenological characteristics of plant communities of Korea using NOAA-AVHRR was identified. Third, NDVI of North Korea is lower on Summer than that of South Korea. And finally, Forest cover is higher than another cover types. Broadleaf forest is highest on may. Outline of covertype profiles was investigated.

Environmental factors such as soil moisture, land management, and weather conditions affecting Fusarium wilt of sweet potato were investigated in major sweet potato cultivation regions in Korea. Fusarium wilt occurred mainly in reclaimed terracing lands, which are flattened and located in hilly to mountainous areas at the base of the mountain, in early seasonal cultivation regions. Disease severity was lower in reclaimed fields with natural slope. The development of Fusarium wilt in the fields was highly correlated with precipitation during planting period (r=-0.96**). Fusarium wilt was more severe in fields with less than 20 cm of available soil depth than in fields with over 20 cm of available soil depth. Greenhouse studies were consistent with field studies that less soil moisture content caused severe Fusarium wilt of sweet potato. These results indicate that low rainfall and moisture of soil with low effective soil depth during planting period are important environmental factors influencing the development of Fusarium wilt.

There are several statistical classification algorithms available for land use/land cover classification. However, each has a certain bias or compromise. Some methods like the parallel piped approach in supervised classification, cannot classify continuous regions within a feature. On the other hand, while unsupervised classification method takes maximum advantage of spectral variability in an image, the maximally separable clusters in spectral space may not do much for our perception of important classes in a given study area. In this research, the output of an ANN algorithm was compared with the Possibilistic c-Means an improvement of the fuzzy c-Means on both moderate resolutions Landsat8 and a high resolution Formosat 2 images. The Formosat 2 image comes with an 8m spectral resolution on the multispectral data. This multispectral image data was resampled to 10m in order to maintain a uniform ratio of 1:3 against Landsat 8 image. Six classes were chosen for analysis including: Dense forest, eucalyptus, water, grassland, wheat and riverine sand. Using a standard false color composite (FCC), the six features reflected differently in the infrared region with wheat producing the brightest pixel values. Signature collection per class was therefore easily obtained for all classifications. The output of both ANN and FCM, were analyzed separately for accuracy and an error matrix generated to assess the quality and accuracy of the classification algorithms. When you compare the results of the two methods on a per-class-basis, ANN had a crisper output compared to PCM which yielded clusters with pixels especially on the moderate resolution Landsat 8 imagery.

This study focuses on the applicability of hill housing design in accordance with topographic characteristics on sloping sites. The urgency for housing still exists but hill sites have to be planned by gradual development using 'all available land' within any particular community. However, there is a reaction towards being more closely involved with nature and landscape. Sloping and hill sites must be developed by intelligent and sensitive planning, integrating the existing environmental factors. The results of this study are as follows : 1. The conditions of location are regarded as the concepts of spactial configuration. It should be developed on the basis of awareness that nature and human beings exist together. 2. It is inevitable that the development of the hill housing should be performed prefer to the topographic characteristics. 3. Planning elements of ecological residental blocks which are possible for constructing on the hill site can be developed and applied, on the basis of geographical characteristics, by housing types.

The study examines economic and environmental impacts of mass tourism on regional tourism destinations, particularly the establishment of "Ten New Bali", in Indonesia. The sample is restricted to the period of time in which annual data is available and comparable among variables from 1980 to 2015 (36 observations). All of the time series data was collected and retrieved from the World Development Indicator database published by the World Bank. This study applies cointegrating regression analysis using the fully modified OLS, canonical cointegrating regression, and dynamic OLS. The results of the study suggest that 1) there is a long-run equilibrium relationship between tourism receipts, environmental degradation and economic growth in Indonesia, 2) tourism growth and agriculture land growth are positively related to an increase of total output in the short-run in Indonesia, and 3) arable land is significant at the 0.01 level, but forest rents and CO2 from transport are not significant in the short-run in Indonesia. The results confirm that arable land is negatively related to an increase of total output in Indonesia. That is, when tourism growth in the economy is getting realized it shows that the environmental degradation increases greatly in inverse in the model, eventually negative impacts to the environment.

Purpose: Lately, The mixed use development on railroad site came up in government policy about securing development available land for public rental housing and social cohesion. The Purpose of this study is to analyze the spatial composition characteristic in housing development example of domestic and foreign through the mixed-use development of railway depot. Method: Site cases are as follows: Shimura Depot(Japan), Kowloon Bay Depot(Hongkong), Chai Wan Depot (Hongkong), Tsuen Wan Depot(Hongkong), Montparnasse Station(France), Euralille Depot(France), Sin Jeong Depot (Korea), Tai Wai Depot(Hongkong), Tseung Kwan O Depot(Hongkong) and Rive Gauche(France). Railway Depot caused various problems such as the lacking of the feeling of solidarity of local inhabitants and the sense of community. In the case of Hong Kong and a France development example to solve these problems, the architectural characteristics appears. Result: At first it is located facilities together such as commerce, duties, the culture. Further, the publicity of the house place is strengthened because an open space, a park are developed on the railroad site. And a variety of connection systems appear between the outside space with a house housing complex built on the artificial ground. Particularly, the development example has an approach and convenience, and it was confirmed that publicness was considerably high.

Composition depending on the development of industrial sites are located just within the existing facilities are hoping to become a retention, in accordance with the law will impose a liability amount. Then calculating the profit and loss analysis of the retention is required. In other words, the composition of the industrial site will be retained for existing facilities and the amount of the profit is necessary to analyze. In this study, the calculation of expenses and the income of retained existing facilities will be presented with analytical methods. Especially the existing cases of dispute with the results of the adjustment and the calculation of contributions for a range of benefits associated with the analysis according to 'The Industrial Sites and Development Act', the following conclusions were drawn. According to 'The Industrial Sites and Development Act', the facility at the industrial site composition within the limits of increasing the convenience of being charged is reasonable. In particular, the industrial site of buildings located within existing facilities depending on the composition and future industrial sites are public facilities available for the facility to consider the possibility of calculating contributions to be reasonable. Additional benefits which can be the land prices, tax exemptions, and increasing efficiency of land use for the benefits are not yet realized the benefits against the expenses side, as well as imposing double taxation. Therefore, the heavy emphasis on convenience is not considered to be reasonable. Including in the industrial site, the cost of damages caused, that is, noise, pollution, and the defective product possibility should be considered a side opinion, but it still does not promote the development of states estimated the cost of the damage is not right to be counted. Therefore, this facility should not be included in calculating contributions.
