  • Traffic represents one of the largest sources of primary air pollutants in urban area. As a consequence, numerous abatement strategies are being pursued to decrease the ambient concentration of pollutants. A characteristics of most of the these strategies is a requirement for accurate data on both the quantity and spatial distribution of emissions to air in the form of an atmospheric emission inventory database. In the case of traffic pollution, such an inventory must be compiled using activity statistics and emission factors for vehicle types. The majority of inventories are compiled using passive data from either surveys or transportation models and by their very nature tend to be out-of-date by the time they are compiled. The study of current trends is towards integrating urban traffic control systems and assessments of the environmental effects of motor vehicles. In this study, a model of vehicle emission calculation by using real-time traffic data was studied. Traffic data, which are required on a street-by-street basis, is obtained from induction loops of traffic control system. It is possible that characteristics of hourly air pollutants emission rates is obtained from hourly traffic volume and speed. An emission rates model is allocated with a high resolution space by using geographic information system (GIS). Vehicle emission model was developed with a high resolution spatial, gridded and hourly emission rates.

  • Recent developments in sensor technologies have provided remotely sensed data with very high spatial resolution. In order to fully utilize the potential of high resolution images, new image classification strategies are necessary. Unfortunately, the high resolution images increase the spectral within-field variability, and the classification accuracy of traditional methods based on pixel-based classification algorithms such as Maximum-Likelihood method may be decreased (Schiewe 2001). Recent development in Object Oriented Classification based on image segmentation algorithms can be used for the classification of forest patches on rugged terrain of Korea. The objectives of this paper are as follows. First, to compare the pros and cons of image classification methods based on pixel-based and object oriented classification algorithm for the forest patch classification. Landsat ETM+ data and IKONOS data will be used for the classification. Second, to investigate ways to increase classification accuracy of forest patches. Supplemental data such as DTM and Forest Type Map of 1:25,000 scale are used for topographic correction and image segmentation. Third, to propose the best classification strategy for forest patch classification in terms of accuracy and data requirement. The research site for this paper is Namhansansung Provincial Park located at the eastern suburb of Seoul Metropolitan City for its diverse forest patch types and data availability. Both Landsat ETM+ and IKONOS data are used for the classification. Preliminary results can be summarized as follows. First, topographic correction of reflectance is essential for the classification of forest patches on rugged terrain. Second, object oriented classification of IKONOS data enables higher classification accuracy compared to Landsat ETM+ and pixel-based classification. Third, multi-stage segmentation is very useful to investigate landscape ecological aspect of forest communities of Korea.

  • MODIS images have a great advantage of high temporal resolution to monitor land cover changes in a large area. The moderate and low spatial resolution satellite images are incomparably economic than high resolution satellite images. As diverse satellite images are provided recently, strategies using satellite images are necessary for continuous, effective and long-term land monitoring. This research purposed to use MODIS images to monitor land cover in Korean peninsula for long-term and continuous change detection. To maximize the advantages of high temporal resolution, the change detection was based on the MODIS temporal profiles of the surface reflectance for one year. In this study as the reflectance patterns of year 2005 were compared with the reflectance patterns of year 2007, the changed pixels could be detected during two years. To set up the threshold value for the decision of change, ASTER images with the higher spatial resolution, 15m, were used for this study. The test area covered the suburban area of metropolitan city, Seoul, where the landcover changes have been frequently happened.

  • NimbleGen has developed strategies to use its high-density oligonucleotide microarray platform (385,000 probes per array) to map both promoter binding sites and copy number variation at very high-resolution in the human genome. Here we describe a genome-wide map of active promoters determined by experimentally locating the sites of transcription imitation complex binding throughout the human genome using microarrays combined with chromatin immunoprecipitation. This map defines 10,567 active promoters corresponding to 6,763 known genes and at least 1,196 un-annotated transcriptional units. Microarray-based comparative genomic hybridisation (CGH) is animportant research tool for investigating chromosomal aberrations frequently associated with complex diseases such as cancer, neuropsychiatric disorders, and congenital developmental disorders. NimbleGen array CGH is an ultra-high resolution (0.5-50 Kb) oligo array platform that can be used to detect amplifications and deletions and map the associated breakpoints on the whole-genome level or with custom fine-tiling arrays. For whole-genome array CGH, probes are tiled through genic and intergenic regions with a median probe spacing of 6 Kb, which provides a comprehensive, unbiased analysis of the genome.

  • Modernized GPS will have three frequencies modulated with three signals, which will be accessible to all users in the near future. This new frequency provides an opportunity to resolve the double differenced (DD) integer ambiguity very fast and with almost no baseline constraints. In order to study the performance of triple frequency system for Ambiguity Resolution (AR) over the medium baseline under different ionospheric levels, the Klobuchar Model was implemented and used in our triple simulation to generate the ionospheric delay. Furthermore, the White-Gaussian noise applying to distance-dependent parameters was added to the DD ionospheric delay. For medium baseline (defined as here 20 to 40kms), success rates of AR has been pretty improved. In this paper, the medium baseline AR strategies that take advantage of carrier phase measurement on the third frequency will be discussed.

  • The current study examined the relationships between the adolescent's conflict resolution style and Big-Five personality factors, self-monitoring and self-esteem. Firstly, results showed that adolescent's big-five personality model affects their conflict resolution styles with their friends and peer group. In detail, the higher the neuroticism was, the stronger became the attack and avoidance strategies. The higher the extraversion was, the higher became the collaborative strategy and the lower became the attack and avoidance strategies. The higher the agreeableness was, the higher became the collaborative strategy and the lower became the attack strategy. The higher the conscientiousness was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the openness to experience was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the self-esteem was, the higher became the collaborative strategy and the lower became the avoidance and attack strategies. The higher the self-monitoring was, the higher became the collaborative strategy and the lower became the avoidance strategy. Secondly, the big-five personality factors also affected the adolescent's conflict resolution styles. The extraversion, conscientiousness, and agreeableness positively affected the collaborative strategy. The neuroticism was positively related with the attack strategy, whereas agreeableness was negatively affected the attack strategy. The neuroticism and agreeableness were positively related with the avoidance strategy, whereas the extraversion was negatively affected the avoidance strategy. Limitations and suggestions for future study were discussed thereafter.

  • This descriptive study was designed to measure the degrees of work stress and job satisfaction and use interpersonal conflict resolution strategy as an attempt to provide clinical nurses basic data to develop strategies releasing work stress and improving job satisfaction. These data were collected from 367 clinical nurses working in 9 hospitals nation-wide from May 1, to June 30, 1998. A structured questionaire was used for data collection. The questionnaire included Kim and Koo's work stress scale, Lee's interpersonal conflict resolution strategy scale and a Minesota satisfaction questionnaire. Data analysis was done by the use of the SAS computer program with descriptive statistics, t -test, ANOVA, Scheffe test, Pearson Correlation Coefficient and Cronbach - ${\alpha}$. The results were as follows 1. The mean score of work stress for the subjects was 4.34(SD=0.64). The highest scored reasons for work stress were 'inadequate com pensation' 4.93(SD=0.86), 'lack of professional knowledge and skill' 4.70(SD=0.92) and 'unsatisfactory relationship with superior authorities' 4.63(SD=0.97). The lowest scored reasons were 'unsatisfactory relationship with inferior staff' 3.72(SD=1.02), 'inadequate mechanical environment' 3.72(SD=1.11) and 'interpersonal problems' 3.85 (SD=1.06), The work stress in clinical nurses differed significantly depending on the hospital type (F=4.00, p=0.0082). 2. The clinical nurses used compromise(45.1%) as the best interpersonal conflict resolution strategy. The second was collaboration(32.8%), the third accomodation(14.2%), the forth avoidance(4.2%) and the fifth competition(3.6%). 3. The item score of job satisfaction of the subject was 3.00(SD=0.43), The job satisfaction in clinical nurses differed significantly depending on age(F=5.67, p=0.0000), marital status(t= -1.89, p=0.0511), academic career(F=5.84, 0.0001), official position (F=7.38, p=0.0001), and work career(F=6.33, p=0.0001). 4. The result of the analysis of relationship between work stress and job satisfaction was significant(r= -0.34, p=0.0000). In conclusion, it was found that work stress was very high in clinical nurses. They used interpersonal conflict resolution strategies to release their interpersonal problems and to increase their job satisfaction. Therefore, adequate stress management for clinical nurses will provide them with higher job satisfaction and hence lead to more qualitified nursing care.

  • Obviously, "informatization" is one of the most effective means for improving national competitiveness. In particular, South Korea is a representative successful case implementing informatization in the world. On the contrary, North Kora does not because of serious information devide matter. Given the assumption that information devide is caused by three aspects: the access to information devices or database(information accessibility); the ability to utilize information resources(information mobilization); and the ability to differentiate the quality of information(information consciousness). Based upon three aspects of information devide, we design practical strategies to implement informatization for North Korea region. The purpose of this study is to investigate how to successfully build in informatization of North Korea region for unification era. Drawing on the analysis of successful cases of South Korea, we suggest the valuable guidelines and directions toward success of building informatization of North Korea region. Therefore, this study provides government with specific and practical success strategies for unification era.
