교통수단의 발달과 경제활동이 활발해짐에 따라 많은 오염문제가 발생하였는데, 특히 대도시를 중심으로 증가한 차량과 경제활동에 필요한 에너지 소비의 증대로 대기오염의 심각성은 더욱 커지게 되었다. 일반적으로 대기중 부유 분진의 발생원은 토사의 재 비산이나 해염 입자, 화분 등과 같은 자연적인 발생원과 산업시설, 소각시설, 가정난방, 수송수단의 이용 등의 인간활동에 의한 인위적인 배출원으로 대별되는데, 인위적인 배출원의 영향은 자연적 발생원에 비해 그 영향이 보다 폭넓고 중요하게 다루어지고 있다. (중략)

작물은 그 종류에 따라서 지대에 따르는 적응성에 차가 있는 것인데 이것은 작물종류에 따라서 각각 적합한 자연적, 사회적인 조건이 다르기 때문이다. 현재 각지에 조성되어 있는 여러가지 종류의 작물의 주산지는 그 대부분이 오랜 시일에 걸쳐서 그 지대에 적응하므로 써 자연적으로 형성된 것이다. 근래 일부에서는 인위적으로 어떤 작물의 주산단지가 조성되는 경우도 있기는 하지만 이러한 경우에 있어서도 그 지대의 자연적, 사회적 조건이 그 작물의 재배에 적합할 때에 비로소 주산단지의 조성이 성공을 거두게 되는 것이다. (중략)

The English language listening environment in Korea nowadays is situated in a quiet and artificial state rather than one of natural exposure. The purpose of this study is to investigate the effectiveness of convergence for pronunciation and listening activities using English advertisements. A survey sample of 40 students was chosen for this study. These 40 students successfully answered the questionnaire and took a 3 hour English course as an elective. Pre and post surveys tests were done for listening ability and learning interests. For the listening tests, TOEIC L.C. test were used and survey questions about interests made by Sunhee Park were revised to be proper used. The results of this study show a positive impact on TOEIC listening ability and that students are able to listen and naturally pronounce more successfully through convergence using English advertisements with higher learning motivation.

Recently, dispersion of damaged forest by pine wilt disease has been regarded as a serious social issue. Damages by pine wilt disease have been spreaded by natural area expansion of the vectors in the damaged area, while the national wide damage spread has induced by human-involved carrying infected trees out of damaged area. In this study, damaged trees were detected and located on the digital map by aerial photograph and terrestrial surveys. The spatial distribution pattern of damaged trees, and the relationship of spatial distribution of damaged trees and some geomorphological factors were geostatistically analysed. Finally, we maked natural spread pattern map of pine wilt disease using geostatistical CART(Classification and Regression Trees) model. This study verified that geostatistical analysis and CART model are useful tools for understanding spatial distribution and natural spread pattern of pine wilt diseases.

RAPD analyses were performed from twenty-four populations of Persicaria thunbergii(Sieb. & Zucc.) H. Gross ex Nakai. The length of amplified DNA fragments ranged from 200 to 1,900bp. 184 scorable RAPD markers were found from PCR reactions with sixteen random oligoprimers. Based on the results, populations of Persicaria thunbergii were classified into disturbance streams of urban and rural streams as well as natural streams. And the populations from natural streams showed having higher genetic similarites than those from highly disturbed streams, Also, the heterogenetic differences between the populations from natural and disturbed areas could be represented the results of the stream environmental changes.

This study aims to examine the impact of Self-leadership(behavior- focused strategies, natural reward and constructive thought pattern to Technology Innovation. Hypotheses were tested by surveying 306 employees at Gumi Industrial Complex. The findings are as follows : First, two factors of Self-leadership had a significant positive effect on the product innovation except constructive thought pattern strategies. Second, two factors of Self-leadership had a significant positive effect on the process innovation except constructive thought pattern strategies.
