목적 : 학습코칭이 대학생의 자기주도학습 능력 및 학업성취에 영향을 미치는지를 살펴보고, 자기주도학습이 학업성취에도 영향을 미치는지 알아보고자 한다. 방법 : 조별 학습 및 팀기반 학습을 6개월 이상 경험한 전남 소재 안경광학과 전공학생 86명을 대상으로 설문조사를 실시하였으며, 수집된 자료는 IBM SPSS Statistics 22를 이용하여 빈도분석, 기술통계량, 신뢰도분석, 회귀분석을 실시하였다. 결과 : 학업성취는 학습코칭과 자기주도학습에 양(+)의 상관관계가 있는 것으로 분석되었다. 학습코칭은 학업성취에 정적인 영향을 미치는 것으로 나타났으며(β=.503, p<.001), 전공만족도가 높을수록 학업성취도가 높은 것으로 나타났다(β=.351, p<.01). 학습코칭이 자기주도학습에 미치는 영향을 살펴본 결과, 유의한 영향을 미치는 것으로 나타났으며(β=.325, p<.01), 남자인 경우(β=.259, p<.01), 학점이 높을수록(β =.222, p<.05) 자기주도학습 수준이 높은 것으로 분석되었다. 자기주도학습이 학업성취에 미치는 영향을 알아보고자 회귀분석을 실시한 결과, 대학생의 자기주도학습은 학업성취에 영향을 미치고(β=.547, p<.001), 전공만족도가 높을수록(β=.404, p<.001) 학업성취에 유의한 영향을 미치는 것으로 나타났다. 결론 : 학습코칭은 대학생의 자기주도학습 및 학업성취에 큰 영향을 미쳤고, 전공만족도가 중요한 변인임을 확인하였다.

The occurrence trends and moleculargenetic characteristics of noroviruses detected from gastroenteritis patients in Jeju from 2008 to 2010 were investigated. In addition, the norovirus contamination and its characteristics of groundwaters in Jeju were examined. The incidence caused by norovirus in viral gastroenteritis patients has increased every year and was higher in male than in female. The patients caused by norovirus occurred throughout all months. The incidences started to increase from November, were very high from December to February, started to decrease from March, and were very low from June to September. The patients caused by norovirus occurred throughout all ages, however, the infants below 5 years were the most susceptible to norovirus infection and the age group from teens to forties were the most insensitive to norovirus infection. The sequencing analysis showed that 18 genotypes (8 genogroup I (GI) and 10 genogroup II (GII)) were detected, the incidences caused by GI and GII were 11.5% and 88.5%, respectively, and predominant genotype was GII-4 (70.5%), which was the major genotype giving rise to norovirus incidences in Jeju, together with GII-3 (6.1%) and GI-4 (4.1%). Among 20 groundwaters sampled at 9 wells (4 non-drinking water wells and 5 drinking water wells), noroviruses were detected from 2 groundwaters sampled at one non-drinking water well and their genotypes were GI-5 and GI-8.
