This study examined the linguistic backgrounds and dialectal characteristics of Changnyeong and Dalseong regions, which are located in the transitional area between Gyeongsangnam-do and Gyeongsangbuk-do. It was confirmed that the language of each region was not severed but share many commonness based on various characteristics found in the transitional area existing discussions and field surveys, As a result, 19 (18) consonants were realized by elderly people and 19 by young people in Changnyeong and Dalseong regions. In the case of vowels, six by elderly people and Seven vowels by young people. Also, it was investigated that language variations, such as Word-initial Glottalization, palatalization, and umlaut, were more active in the Changnyeong region than Dalseong region. The difference between these three variations can be attributed to the perceptions and attitudes of older speakers.

Oral squamous cell carcinoma (OSCC) develops through multistep process, that is, from normal mucosa to hyperplastic area and progressed to dysplasia, carcinoma in situ, and finally to invasive carcinoma. The purpose of this study is to investigate the histological types of the transitional area from normal oral mucosa to invasive carcinoma for the baseline data to search intermediate end point markers for early detection of OSCC. For this purpose, we reviewed the 85 patients who were diagnosed as OSCC in the Department of Oral Pathology, Yonsei University College of Dentistry, from 2002 to 2008. We classified these histopathologic findings by light-microscopy, according to the histologic pattern of transitional areas. As results, stepwise transformation from normal oral mucosa, to dysplasia and to OSCC was shown in 47 patients. Intermittent lesions were seen in 16 patients, in which normal oral mucosa, dysplasia, and OSCC were alternately arranged. Twenty two patients showed abruptly transformed to OSCC from normal oral mucosa. These preliminary data will be used for searching biomarkers for early detection of OSCC.

일반적으로 토양의 경우 천매암 및 셰일 지역이 높은 원소 함량을 보였고 원소의 상관관계에서 셰일 지역이 많은 원소에서 높은 상관관계를 보였다. 지역에 따른 인삼의 2년근과 3년근의 비교에서 2년근에서 높았는데, 특히 화강암과 편마암지역이 셰일지역에 비해 2년근에서 두드러지게 높았다. 같은 연령 인삼들의 지역적 비교에서 화강암지역이 낮았으며, 셰일 및 천매암의 비교에서는 셰일이 높았다. 인삼의 부위 별 비교에서 2년근과 3년근에 관계 없이 상부가 높은 원소함량을 보였다 토양과 인삼 평균치와의 비교에서 대부분 원소가 인삼 조성에 비해 토양에서 높은 함량을 보였고, 토양과 인삼조성 관계에서 유사한 증감 경향을 보였다. 전체적으로 일반적인 전이원소의 부정적인 영향을 전제로 하면 세 토양중 화강암 지역이 인삼의 최적지이며 셰일 지역이 제일 불리한 지역임을 암시한다.
