두 개의 딸기 온실 (농약살포포장, 천적방사포장)에서 점박이응애(Tetranychus urticae Koch)의 고정 정확도 수준에서 표본조사법 (Fixed-precision sampling plan)을 개발하였다. 표본추출은 조사구역당 3개엽으로 이루어진 복엽 1줄기를 기준으로 하여 3줄기를 채취하였다. 각 복엽은 Relative net precision (RNP) 값을 비교하기 위해 3개의 서로 다른 단위(1엽, 2엽, 3엽)로 나뉘어졌다. RNP 값 결과 1엽 단위가 다른 단위들보다 정확도와 효율적인 면에서 우수했다. 공간분포 분석은 Taylor's power law (TPL)를 이용하였으며, 각 딸기 온실별로 계산된 TPL 계수의 동질성검정에는 공분산분석(ANCOVA)을 이용하였으며, 분석결과 차이를 보이지 않았다. 표본추출 정시선을 구하기 위한 TPL 계수는 농약살포포장과 천적방사포장의 딸기 1엽 단위에서 점박이응애 밀도 자료를 합한 뒤 재계산하여 사용하였다. 그리고 점박이응애 발생밀도수준을 3마리와 10마리로 설정하여 방제의사를 결정하였다. 분석에 사용하지 않은 독립된 자료를 이용하여 개발된 표본추출법의 유효성을 Resampling Validation for sampling plan (RVSP)으로 확인한 결과 적합한 정확도를 보였다.

PURPOSE: The purpose of this study was to investigate any changes in abdominal muscle activity after curl-up and jack-knife exercisse using a sling and swiss-ball. METHODS: Sixteen asymptomatic subjects were randomly assigned into either a sling exercise group (SG) or swiss-ball exercise group (SBG). Subjects performed curl-up and jack-knife exercise using sling and swiss ball. Activity of abdominal muscles (rectus abdominis and external oblique) was assessed using surface electromyography (EMG) and normalized maximal voluntary isometric contraction (MVIC) before and after exercises. The significance of differences between the SG and the SBG was evaluated by analysis of covariance (ANCOVA). RESULTS: There was an increase in activity of all abdominal muscles after the curl-up and jack-knife exercises for 6 weeks. However, there was not a significant difference between the SG and the SBG after curl-up exercise (p>.05). There was also not a significant difference between the SG and the SBG after Jack-knife exercise (p>.05) except for the right external oblique muscle (p<.05). CONCLUSION: Exercises on an unstable surface using a sling and swiss ball are effective ways of abdominal muscle exercise.

According to Piaget, children aged 11 are in the middle of concrete operation period and formal operation period. So, it is necessary to adopt the Learning Cycle Model (LCM) which helps students improve their cognitive development. After determining the test for the Science Concept of Matter (SCOM), the experimental group showed higher average than the comparative group in the post-test. In the sound understanding, the experimental group showed higher ratio than the comparative group. And in the ratio of imperfect, wrong understanding and no response, the experimental group was lower than the comparative group. On the questions that were needed the complicated inquiry, many students of both groups still couldn't find the fundamental cause. In forming the scientific conceptualization, there was a meaningful difference (p < .001) after post-test Analysis of Covariance (ANCOVA) with pre-test result. After determining the test for the Test Inquiry Science Process (TISP), the experimental group showed higher average than the comparative group in the post-test. In the category of basic inquiry process which is needed in concrete operation, there was a meaningful difference (p < .05). In the category of unified inquiry process which is needed in formal operation, they showed no meaningful difference (p > .05). Therefore, applying the LCM to the chapter of 'Solution and Dissolving' is more effective on improving the scientific conceptualization and on helping the concrete operation abilities than the teacher centered learning.

Food literacy (FL) refers to the ability to understand and utilize food information. This concept consists of functional (FFL), interactive (IFL), and critical food literacy (CFL). In today's massive information-driven society, FL needs must be paid attention to as a determinant of health along with health literacy. This study sought to identify the FL of Korean adults, and to analyze the association between FL and nutritional status. Data was collected through an online self-reported survey among 1,355 Korean adults aged 19 to 64 years, stratified by gender and age. An χ² -test, student's t-test, ANOVA, analysis of covariance (ANCOVA), and multinomial logistic regression were performed using IBM SPSS 25.0. There were significant differences in the subjects' FFL, IFL, and CFL according to their gender, age, residence area, work type, and monthly income. Furthermore, it was confirmed that subjects with a higher nutrition quotient (NQ) grade also had higher FLs. Additionally, FFL and CFL contributed to improving the NQ grade. This study is meaningful in that it investigated the FL of Korean adults and provided data to identify populations that are particularly vulnerable to a lack of FL. In addition, it was confirmed that FL can have a positive effect on the nutritional status of adults. In conclusion, this study suggests the possibility of using FL as an intervention strategy to improve nutrition.
