기후변화에 관한 정부간 합의체 (IPCC, Intergovernmental Panel on Climate Change) 6차 보고서에서 이번 세기 중반까지 현 수준의 온실가스 배출량을 유지한다면 2021~2040년 중 1.5℃를 초과할 것이다. 이러한 기후의 변화로 인한 기온상승 영향으로 과거와는 달리 산림변화는 과거와 다르게 침엽수는 감소하고 활엽수는 증가하는 추세다. 본 연구에서는 유역 대부분이 산림으로 금강 상류의 용담댐유역 (930.2 km²)을 대상으로 SWAT (Soil and Water Assessment Tool)을 이용하여 장기간 산림변화에 따른 수문 구성요소를 평가하였다. MOD15A2 LAI 및 임상도 자료를 10년 단위 (1980s (1980~1989), 2000s (2000~2009), 2010s (2010~2019))를 이용해 임상별 (침엽수림, 활엽수림, 혼효림) 및 산림 높이를 구축하였다. 임상별 산정된 LAI를 기초로 SWAT의 임상별 LAI 및 수문 검·보정을 통해 용담댐유역 현황을 재현하였다. 모형의 적용성 평가는 R²를 이용하였으며, 임상별 (침엽수, 활엽수, 혼효림) LAI는 0.95, 0.89, 0.90로 증발산량은 0.51, 토양수분은 0.5~0.55로 유량의 경우 0.69로 산정되었다. 산림변화에 따른 1980s는 LAI 자료가 없기에 2000s 및 2010s의 식생 높이 및 LAI를 멱함수로 회귀하여 1980s 엽면적지수를 산정하였다. 기상자료는 2010s로 고정하고 산림 성장이 물순환에 미치는 영향을 1980s 및 2010s의 수문 비교를 시공간적으로 평가할 예정이다.

This study examined the relationship between the number of medical technologists and the medical test count. Data was obtained from 441 medical technologists in a hospital through a self-reported questionnaire. The Pearson correlation test, student's t-test, ANOVA or descriptive statistics were performed for data analysis. The distribution of medical technologist according to the size of hospitals was small 5.8, medium 14.9, large 25.8, and super 45.4. The analysis demonstrated a relationship between the number of medical technologists and the number of medical tests in the field, number of clinical tests per MT, and number of optimal medical test per MT according to the hospital size (P<0.001). The average time for quality control by the department at a higher hospital was less than two hours. In terms of the satisfaction of salary, work environment, test accomplishment, and welfare service, the dissatisfaction of medical technologists in small and medium hospitals was higher than those in large and super hospitals. Overall, a focus on intensifying systemic supplementation and improving the condition of medical technologists is needed to provide reliable data for medical examinations in medical areas.

This study will be used as basic data to hold clinical training effective by researching and analyzing frequency, satisfaction and stress for the clinical practice of dental hygiene course students. The survey was undergone from Feb. 1, 2014 to Mar. 31 for 219 dental hygiene course juniors who had experienced clinical training in 3 year colleges located in Daejeon and Chungcheong Province. From the study, general and university hospital holds the highest satisfaction in clinical practice and dental offices in acquiring skills. Also, a significant difference is shown between the frequency and satisfaction according to clinical training sheets. The highest degree of stress is shown in dental offices for 'toothbrushing training and dental health education' and in general and university hospital for 'patient counselling'. Therefore, consideration should be made to establish the direction of education, standard criteria and evaluation method for student clinical training to raise its effectiveness.

Since 2006, the $5^{th}$ National Forest Inventory (NFI) has been implemented to provide forest resources statistics at the national level and at the county level as well. However, it needs a small-area estimator for estimating forest statistics at the county-level due to a small number of samples collected within a county. This study was conducted to evaluate the applicability of a geographical-based synthetic estimator for estimating forest growing stock volumes at the county level. The NFI-field plots surveyed were post-stratified into three forest cover types. In the synthetic estimator, field plots within a geographical-based super-county for each county were used to estimate stratum weights and stratum mean volumes. It was resulted that estimated stratum weights using the synthetic estimation were significantly differ from forest cover maps. The standard errors of estimated mean by the synthetic estimation that ranged from ${\pm}3.5\;m^3$/ha to ${\pm}7.7\;m^3$/ha were more smaller than those (${\pm}7.8\;m^3/ha{\sim}{\pm}24.7\;m^3/ha$) by the direct estimation. This means that the synthetic estimation is possible to provide more precise estimates of mean volumes.

The present study analyzes the main factor having an effect on the convergence dental hygienist's self-esteem through the survey to them. A self-leadership and professional self-conception show meaningful result with higher score in the group with higher self-respect than that of lower one(p<.001). Also the higher hygienist's self-esteem, the higher clinic practice ability(p<.01). There is negative correlation with self-esteem in emotional labor(p<.01) and exhaustion(p<.01). However, the positive correlations are presented in self-leadership(p<.01), professional self-conception(p<.01) and clinic practice ability(p<.01) with self-respect. The factors influenced on self-esteem are clinic practice ability(p<.05) and exhaustion(p<.01). In results, the organized convergence program and education considering self-esteem in the hospital should be accomplished systemically to enhance the clinic practice ability of each hygienist.

현재 비점오염원의 정량화를 위하여 정부에서는 지목별 모니터링을 통하여 원단위를 산정하고 있으며, 이를 이용해 수질개선을 위한 수질오염총량관리제를 더욱 효과적으로 운영 평가하기 위한 노력을 하고 있다. 특히, 전 국토의 70% 이상을 차지하고 있는 산림에서 발생되는 유출수에 대한 특성을 파악하는 것이 중요하다. 보통 산림 유출 특성은 모니터링을 수행하여 파악하는 것이 가장 정확한 방법이지만, 지형 작물 시간 강우 패턴 등의 다양한 조건에서 모니터링을 수행하는 것이 어렵다. 또한 지점선정 장비구입 인건비 등 많은 비용이 요구되어 모델링을 통해 시 공간적으로 유출 특성을 평가하고자 하는 연구들이 활발히 진행 중이다. 본 연구는 GIS에서 WEPP 모형의 구동이 가능하게 된 GeoWEPP 모형을 이용하여 활엽수림 침엽수림 혼효림에서 강우시 발생하는 유출량을 모의하여 실측 유출량과의 비교 평가를 통해서 GeoWEPP 모형의 정확성을 평가하는데 있다. 모델 평가를 위해 $R^2$와 Nash-Sutcliffe model Efficiency (NSE)를 사용하였다. 활엽수림 지점은 2009년 총 10개의 강우 발생으로부터 유출량이 산정되었는데, $R^2$와 NSE는 각각 0.98와 0.87로 나타났다. 침엽수림 지점은 14개의 강우 발생시 산정된 유출을 이용하여 모델을 평가하였는데, $R^2$와 NSE가 각각 0.91와 0.90으로 나타났다. 혼효림 지점은 총 10개의 강우 발생시 산정된 유출을 이용하여 모델을 평가한 결과 $R^2$와 NSE가 각각 0.98와 0.94로 나타나 GeoWEPP 모델이 임상별 유출량을 잘 반영하는 것으로 나타났다. 본 연구 결과에서 보이는 바와 같이 GeoWEPP 모형이 임상별 유출특성을 매우 정확하게 예측할 수 있다고 판단된다.
