This study analyze the trend and creativity of entry in chemistry sector of National Science Exhibition. For this study, award-winning entry in chemistry sector of National Science Exhibition during the last five years (2009-2013) were analyzed. The inquiry subject were classified six different items. The creativity evaluation rating of each entry was decided by a survey of the evaluator groups; teachers who participated in the training, winners' teacher. The results turned out as follows: First, In case of trying to choose inquiry subject of entry, it would be better for teacher to guide student into choosing everyday life or natural phenomenon in elementary school level, everyday life or academic area in middle school level, academic area in high school. Second, there was no correlation of creativity rating and actual award rating. Therefore, teacher will need to guide students' research synthetically in a variety of research areas.

육우는 일반적으로 홀스타인의 수소나 미경산 암소를 비육하여 출하하는 고기소다. 홀스타인 자체가 우유생산을 목적으로 개량되어 옴에 따라 다른 육용종 소에 비해 육질적인 측면에서 불리한 부분이 있지만 사양관리 방법에 따라 등급판정결과는 크게 달라질 수 있다. 따라서 지난해 등급판정결과에 대한 분석을 통해 육우사육의 현황과 앞으로의 방향에 대해 살펴보기로 하자.

In this study, groundwater quality data measured for 11 years from 2006 to 2016 were analyzed statistically for 101 civil defense emergency water supply facilities (CDEWSF) in the Gwangju area. The contamination level was quantified into four grades by using excess drinking water quality standards, average concentration analysis, and tendency analysis results for each facility. On the basis of this approach, the groundwater contamination degree of each item was evaluated according to land use status, installation year, depth, and geological distribution. The contamination grade ratios, which were obtained by analyzing three contamination indicators (water quality exceeded frequency, average concentration analysis, and trend analysis) for 15 items on statistically significant of civil defense emergency water was relatively high, in the order of Turbidity (51.5 %) > Color (32.7 %) > Nitrate nitrogen (28.7 %) > Hardness (25.7 %). As a result of the contamination grade analysis, except for the items of Turbidity, Color, and Nitrate nitrogen, the contamination levels were distributed in various degrees from "clean (0)" to "seriously contaminated (3)." Regarding the contamination grade of 12 items, 25 % of the total were classified as "possibly contaminated (1)," and 75 % were rated "clean (0)." The four items (Turbidity, Color, Nitrate nitrogen, and Hardness) for which contamination indication rate were evaluated as "high" by the were visualized on a contamination map.
