This study was conducted to investigate the concentration of the heavy metals among the soils and crops, and the difference compared with the unpolluted area from the radius distance from the ruined mine. Gubong Mind in Cheongyang-Gun, Chungnam-Do was selected as the ruined mine, which the Taechi-Myon district was selected ad the unpolluted control area. Pepper, welch onion, cabbage, radish and their soils were collected at the mine and unpolluted area, respectively. The concentration of heavy metals(Pb, Cd, Cu, Zn and As) were measured by ICP. In the soil sample, the average concentrations of all the heavy metals were significantly increased in the min area compared with those of the unpolluted area and significantly differed from the radius distance from ruined mine. In the crop sample, the average concentration of Pb, Zn and As metals were significantly increased in the mine area compared with those of the unpolluted area and all the heavy metals were significantly differed from the radius distance from ruined mine. There was a significant negative correlation among the soils from the radius distance from ruined mine and among the crops in the concentrations of all the heavy metals. There was a significant positive correlation between soils and crops in concentration of Pb, Cd, Zn and As metals. The results indicate the concentrations of heavy metals among the soils and crops at the ruined mine were saturated more than the unpolluted and the soil metals had spread to the crops. Consequently, we cannot leave the matter unsettled and its utilization must be studied to lower the contamination degree.

저위교합 유구치에서의 공간확장술을 이용한 외과적 접근

방석윤,김은정,김현정,김영진,남순현 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

저위교합이란 능동적 맹출기 동안이나 이후 해당치아의 교합면 방향으로의 성장이 멈추어 다른 치아들보다 하방에 존재하는 것을 말한다 저위교합치의 결과로 침하치의 만기잔존, 부정교합, 증가된 치아우식 감수성과 치주질환의 가능성, 계승치의 이동 등이 나타날 수 있다. 따라서 조기진단 및 적절한 처치가 필요하다. 저위교합치의 치료는 저위교합 정도나 후속 영구치의 발육정도에 따라 보존에서 발치까지 다양하다. 영구 계승치가 없거나 부분적인 침하치가 치주적으로 건전한 경우, 공간문제를 발생하지 않는 경우 보존적인 접근이 추천되기도 한다. 그러나 계승치가 존재하고 맹출이 지연되는 경우, 국소적인 염증반응과 관련되는 경우 교정적인 치료가 필요한 경우에는 발거가 필요할 수도 있다. 특히 저위교합된 유구치의 상방으로 인접치가 경사되어 악궁장경에 문제를 초래할 위험이 있는 경우 외과적인 발치가 필요할 수도 있으며 경사가 심한 경우 발치를 위한 외과적 접근이 힘들 수 있다. 심하게 경사된 인접치로 인하여 저위교합치의 외과적 발거가 힘들 환아에서 가철성 교정장치를 이용하여 공간확보를 진행 하였으며 보다 용이하게 치아를 발거할 수 있었다. Infraclusion may be defined as teeth that stop their relative occlusal movement in the dental arches during or after the period of active eruption and then remain under the occlusal plane. Delayed exfoliation, malocclusion, increased susceptibility to dental caries and periodontal disease of both the neighboring teeth and retained molar, and dislocation of' the successor are the consequencces of infraclusion of primary molars. Therefore, early diagnosis and appropriate treatments are necessary. The therapeutic approach of' the infracluded teeth varied from preservation to extraction. The teeth with simple infraclusion without any signs of interference with occlusal and jaw development may be examined periodically with fellow-up check and radiographically. However, if the infracluded tooth interferes with normal eruption of successor or shows any sign of delayed resorption, or the tipping of adjacent teeth or supraeruption of op-posing teeth is expected, the teeth inflicted should be extracted and appropriate measures should be provided in order to maintain the normal development of occlusion and dentition. The adjacent teeth which have been collapsed over a infracluded deciduous teeth can disturb the arch length perimeter. In such cases, surgical approach might be necessary, although it would be difficult when teeth are severly leaned. However, an easier surgical access have been obtained by space regaining procedures, in young patients whose arch length has been shortened due to the infracluded teeth.

정영민,김동연,은종방,박근형 全南大學校 農漁村開發硏究所 1991 農業科學技術硏究 Vol.26 No.-

차광도가 다른 재배환경이 다엽의 Chlorophyll 색소함량에 미치는 영향을 조사하고자, 재배차의 무차광 및 차광다엽, 그리고 야생차의 연중 반차광다엽과 연중 차광다엽을 대상으로 검토한 결과, Chlorophyll의 함량은 차광 정도에 따라 차이를 보였는데 무차광다엽보다 차광다엽이 높은 경향을 나타냈다. Chlorophyll a와 b의 조성은 무차광다엽은 3:1, 그리고 차광다엽은 2.8:1로 그늘에서 자란 것이 Chlorophyll b의 비율이 증가하는 경향을 나타냈다. The effect of shading on the Chlorophyll content of tea shoot was examined under the different shading conditions shaded and unshaded tea shoots obtained from cultivating tea were analyzed while partial shaded and through-shaded tea shoots were used for wild tea. Analysis of the Cholorophyll contents of tea shoots revealed that different shading conditions resulted in different Chlorophyll contents and higher content of Chlorophyll was found in the shaded case. The composition of Chlorophyll a and b was 3:1 and 2.8:1 under unshaded and shaded conditions respectively, which indicated that the ratio of Chlorophyll b to Chlorophyll a increased under the shading condition.

Background: Trichophyton (T.) verrucosum is a dermatophyte causing ringworm in cattle, distributed worldwide. It can be responsible for various inflammatory lesions of skin and scalp. In Korea, kerion celsi caused by T. verrucosum was first reported at 1986 in the southeast province of Korea. Since then, many patients infected with T. verrucosum have been reported in Young-nam province. There are few long-term studies about epidemiological characteristics of T. verrucosum. Objectives: To investigate the clinical and epidemiological characteristics of T. verrucosum infections in Korea. Methods: A total of 224 patients were diagnosed as T. verrucosum infection by fungal culture from 1976 to 2015. The data were based on a retrospective survey of medical records. Results: The annual incidence of patients with T. verrucosum infection had been increasing since the report in 1986. The number of patients showed a peak in 1988. After 2000, the number of patients had been decreasing. Female to male ratio showed a 1.2-fold predominance of female infection. And more than 15-year-old group was 59.4% of total patients. T. verrucosum infection was most commonly seen in spring and was found predominantly in patients living in rural areas. Face was most frequently involved, followed by arms. Conclusion: These findings provide useful information for understanding of T. verrucosum infection and future dermatophytosis prospects.

성덕경,방경윤,오영륙,최은호,안일신,김옥경 한양대학교 이학기술연구소 2003 이학기술연구지 Vol.6 No.-

Spectroscopic ellipsometry 은 다양한 물질의 광학적 특징을 연구할 수 있는 강력한 기술이다. 현재 실리콘 웨이퍼 위의 박막 분석에는 그 효율성이 확실히 입증되어 있다. 그러나 현재 산업은 유리 기판위의 박막을 분석하기를 원하고 있다. Ellipsometry로 투명기판을 분석하기 위해서는 후면 반사에의한 비간섭성 효과를 고려해야 한다. 기존의 반사공식을 투명기판의 비간섭성을 고려하여 수정하였다. 투명기판 위의 샘플과 scratch를 낸 같은 샘플을 측정 분석하여 정확성을 확인하였다. 수정된 반사공식을 이용하면 디스플레이와 같은 투명재료를 이용하는 곳에 유용하게 사용될 것으로 기대되고 있다. A Spectroscpic ellipsometry is very strong technology to study optical properties of many materials. It has already substantiated a analytic efficiency about thin films above wafers to be made of silicon. However, the current industry needs thin films analyzed on a glass. When we analyze a glass using a ellipsometry, we have to consider a efficiency of incoherence due to reflect at the back side. So then, we slightly altered the original formula. We compared a scratched sample with a sample on the glass, because off getting a exactitude. Our technical development, using the changed formula, is expected the useful utilization in a part of using gIasses such as display.
