  • This study investigated the distribution behaviors of PM2.5 and PM10 at two air quality monitoring sites, Go-eup (GO) and Backseokeup (BS), located in Yangju City, South Korea. The amounts of emissions sources of pollutants were analyzed based on the Clean Air Policy Support System (CAPSS), and the contribution rates of neighboring cities were enumerated in Yangju. Yangju has a geological basin structure, and it is a city with mixed urban and rural characteristics. The emission concentration of particulate matter was affected by geological and seasonal factors for all sites observed in this study. Therefore, these factors should be considered when establishing policies related to particulate matter. Because the official GO and BS station sites in Yangju are both situated in the southern part of the city, the representativeness of both stations was checked using correlation analysis for the measurement of PM2.5 and PM10 by considering two more sites-those of Bongyang-dong (BY) and the Gumjun (GJ) industrial complex. The data included discharge amounts for business types 4 and 5, which were not sufficiently considered in the CAPSS estimates. Because the 4 and 5 types of businesses represent over 92.6% of businesses in this city, they are workplaces in Yangju that have a significant effect on the total air pollutant emission. These types of businesses should be re-inspected as the main discharge sources in industry, and basic data accumulation should be carried out. Moreover, to manage the emission of particulate matter, attainable countermeasures for the main sources of these emissions should be prepared in a prioritized fashion; such countermeasures include prohibition of backyard burning, supervision of charcoal kilns, and management of livestock excretions and fugitive dust in construction sites and on roads. The contribution rates by neighboring cities was enumerated between 6.3% and 10.9% for PM2.5. Cooperation policies are thought to be required with neighboring cites to reduce particulate matter.

  • This study aims to explicate the properties of the existing xylographic books in Buddhism published in the old region of Yangju. Gyeonggi-do by investigating them and carrying out the analyses of them. For this, we have investigated, in addition to literature and xylographic bibles, Buddhist books which are now possessed by principal libraries and temples in Yangju. 99 kinds of Buddhist books had been published by 14 temples at the region of Yangju. It is in the late Chosun that Buddhist books in the region of Yangju were actively published. Bulamsa has published the greatest amount of 53 kinds of books. we can and out that Buddhist bibles were actively published, and uncanonical books and Esoteric Buddhist bibles with strong characteristics of worldly benedictions and Praja-Paramita emphasizing the thought of emptiness. As for publishing methods, 85 kinds of books were xylographic and 14 kinds of books were published with wooden types. There were direct and indirect supports from the ruling class on most of the temples that published Buddhist books. Temples happened to co-publish Buddhist books.

  • Recently, agricultural lands have decreased sharply, which was caused by huge housing site, urbanization, land consolidation, and road construction etc. In particular, Yangju city near Seoul city has the most severe land use change in Korea. Therefore, we analyzed changes of land use, soil properties, and soil information in order to provide the basic soil information and soil management practices in this city. The area of crop cultivated land in Korea (2015) reduced by 12,090 ha compared to ones from the previous year (2014). The paddy field decreased by 25,421 ha but, upland field increased by 13,331 ha. One of the reasons for the reduction of the paddy field was converting paddy field to upland (20,916 ha) > others (3,056) > building (2,571) > public facilities (847) > idle land (217). But, reasons for increase of upland field were switching paddy to upland (20,916 ha) > land developed (634). The main reason of converting paddy field to upland was changing from rice to more profitable speciality crops or pulses. The cropland area (paddy fields, upland, orchard) of Yangju city reduced by 1,412 ha (2015/2014). The ratio of cropland area in each city reduced by 22.9% dramatically compared 2015 to 1999. The paddy fields located in alluvial plains in Yangju city were changed into upland or green house. The drainage classes of soil have been deteriorated because the flows of water were intercepted by road construction and other disturbance to water flows. In particular, paddy fields have been changed to not only upland, orchard, greenhouse cultivation but also to fallow and soil dressing on paddy in Yangju city. To analyze result of soil survey of Yangju city, 858 soil codes (soil phases) were used and the area was 105.17ha. The number of soil series increased from 60 to 65, and that of soil phase increased from 105 to 124. The largest increased area was Noegog soil series. 125.7ha of Neogog soil series was incorporated from the existing Sachon, Yecheon and Eungog soil series. The soil suitability class of paddy field in Ogjung huge housing site of Yangju city was the 4th grade for 32.6% of the area. The soil suitability classes of upland were 2nd and 3rd grade for 72.4% of the area. Farm land with high quality should be conserved by related law.

  • Purpose: Meniscal injuries are very common sports problems and indications for knee surgery. We analyzed the effectiveness of joint line tenderness retrospectively. Materials and Methods: From May 2005 to June 2006, 76 knees which were diagnosed meniscal injury and performed arthroscopic surgery by same surgeon at military hospital were included. We analyzed sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of joint line tenderness in meniscal diagnosis. Results: The joint line tenderness gave such results (78.8%, 32.6%, 52.6%, 47.3%, 66.7% for sensitivity, specificity, accuracy, positive predictive value, negative predictive value respectively). We got similar results in analyses with medial meniscal lesion, lateral meniscal lesion, and combined instability patients. Conclusion: The joint line tenderness is a easy and comfortable maneuver but, it's effectiveness is low when it is used lonely The composite examinations including MRI and diagnostic arthroscopy for meniscal injuries of the knee perform much better than joint line tenderness alone.
