This study aims to identify the effects and traits of narrative online group counseling for college students by comparing them with face-to-face group counseling. For this purpose, 18 college students were assigned as experimental group (videoconferencing method, using "Zoom"), comparison group (face-to-face method), and control group (no treatment). 8 sessions of narrative group counseling program was conducted for two groups. The difference between pre- and post test scores of 'self-identity' and 'relationship' showed significant improvement in 'self-identity' in both experimental and comparison groups, while positive change in 'relationship' was only significant in the experimental group. The traits of online group counseling experience were identified by comparing the post-interview data asking about their counseling experiences. In conclusion, we found that despite the various limitations, the context of online group counseling showed similar effects to face-to-face group counseling, and suggested a direction for the development of online group counseling.

The purpose of this study is to investigate the impact of argument-based modeling strategy using scientific writing on student's modeling ability. For this study, 66 students (three classes) from the 7th grade were selected and of these, 43 students (two classes) were assigned to two experimental groups while the other 23 students (one class) were assigned to comparative group. In the experimental groups, one group (22 students) was Argument-based multimodal Representation and Modeling (AbRM), and the other group (21 students) was Argument-based Modeling (AbM). Modeling ability consisted of identifying the problem, structuring of scientific concepts, adequacy of claim and evidence and index of multimodal representation. As for the modeling ability, AbRM group scored significantly higher than the other groups, AbM group was significantly higher than comparative group. The four sub-elements of modeling ability in the AbRM group was significantly higher than the other groups statistically and AbM group scored significantly higher than comparative group. From these results, the argument-based modeling strategy using scientific writing was effective on students' modeling ability. Students organized or expressed the model and evaluated or modified it through the process of argument-based modeling using scientific writing and the exchange of opinions with others by scientific language as argument and writing.

한국산 도룡농, Hvnobius leechii의 7개 집단에서 mitochondrial DNA(mtDNA)의 변이가 조사되었다. MtDNA의 크기에서의 차이는 관찰되지 않았으나 제한효소 인식 부위에서의 차이가 조사되었다. MtDNA의 절편 양상은 각 집단에서 동일하게 나타났다. 제한 효소로 처리하여 얻어진 절편의 비교에서 종내 변이는 염기 치환에 의하여 발생한 것임이 분석되어졌다. 특히 하동과 제주 집단은 몇개의 제한 효소 인식 위치에서 나머지 5개 집단과 뚜렷한 차이를 보였다. 염기치환율(p값)은 공통 절편 비율(p값)을 토대로 하여 얻어졌으며 그 값은 0.004에서 0.064의 범위 내의 값으로 측정되었다. 하동과 제주 집단을 제외한 5개 집단의 비교에서는 비교적 낮은 침의 염기 치환율을 보였으나 제주와 나머지 집단들과의 비교에서는 염기치환율이 높게 측정되었다. 염기 치환율과 관련지어 염기 분화 연대를 측정한 결과 도룡뇽 7개 집단은 3개의 group으로 나뉘어 졌으며 이들은 약 188만년전에 분화된 것으로 사료되어 진다.

본 연구의 목적은 수학교실에서 의사소통 불안에 따른 이질 집단과 동질 집단으로 소집단 구성을 달리하였을 때 정의적 영역에서 소집단 협동학습 효과의 차이가 있는지 알아보는데 있다. 이러한 연구 목적을 달성하기 위해 다음과 같은 연구 문제를 설정하였다. 첫째, 의사소통 불안에 따른 동질 집단과 이질 집단간에 정의적 영역(수학적 태도, 자아존중감)에서 차이가 있는가? 둘째, 동질 집단과 이질 집단간의 비교에서 어느 집단의 불안 수준이 정의적 영역(수학적 태도, 자아존중감)에 더 긍정적인 효과가 있는가? 이러한 연구 문제를 해결하기 위하여 독립변인은 협동학습에서의 의사소통 불안에 따른 집단 구성 형태이고 종속변인은 정의적 영역(수학적 태도와 자아존중감)인 원인비교 연구 설계(casual-comparative research design)를 세워 원인비교 연구를 실시하였다. 본 연구의 결과로부터 다음과 같은 결론을 얻을 수 있다. 첫째, 의사소통 불안에 따른 집단 구성방법이 수학과 소집단 협동학습의 효과, 특히 자아존중감 향상에 영향을 끼치기 때문에, 효과적인 협동학습을 위해서 학생들의 의사소통 불안을 측정하여 이질 집단으로 구성할 필요가 있다. 둘째, 의사소통 불안에 따른 집단 구성을 했을 때 이질 집단의 불안 하위수준 학생들이 자아존중감 향상에 가장 큰 효과를 볼 수 있다. 결론적으로, 수학 교실에서의 의사소통 불안은 집단의 상호작용 행동에 영향을 준다고 말할 수 있고 의사소통 불안에 따른 이질 집단은 자아존중감 향상에 효과적인 집단 구성방법임을 시사한다.

The purpose of this study was to determine the possible additive effects of endurance exercise training (EXER) and selenium (SELE) on the improvements of glucose and lactate transport capacities in diabetic Goto-kakizaki rats. Animals either remained sedentary control (SED) or performed EXER or received SELE [$5{\mu}mol$ kg body wt (-1) day (-1)], or underwent both EXER and SELE (COMBI), which lasted for 6 wk. Compared with sedentary control, EXER alone or the SELE alone group, or the combined treatment group had significant reduction in glucose response measured at 90 min and 120 min during an intraperitoneal glucose tolerance test (IPGTT) and body weight after 6week treatment. EXER alone, or combined group individually had significantly higher glycogen contents in liver compared with SED or SELE groups. EXER alone increased glycogen content in soleus and plantaris compared with SED, and this parameter was increased to greatest extent in the combined treatment groups compared with SED or SELE groups. EXER alone, SELE alone or COMBI, caused significant decreases in the plasma lactates, serum glucose, insulin, total cholesterol and HOMA-IR along with a significant increase in high-density lipoprotein cholesterol compared with SED. In addition, EXER or COMBI individually had significantly lower serum triacylglycerol compared with SED or SELE. With respect to protein expression related to glucose and lactate transport capacities, EXER alone, SELE alone, or COMBI increased in MCT1 and MCT4 protein level in soleus and plantaris. Furthermore, EXER alone, SELE alone or COMBI caused significant increases in mt MCT1 protein level in soleus and plantaris. The findings of the current study suggest that endurance exercise training and selenium treatment may provide therapeutic values to type II diabetic patients with peripheral insulin resistance and hyperlactatecemia by improving glucose and lactate transport capacities, leading to improvements in plasma lactate, serum glucose, insulin and lipid profiles (TC, TG, HDL).

This study explored the changes in nutrition knowledge and eating habits formation of infants through vegetable gardening activities in early childhood education institutions. children from H nursery school located in Suwon-si, Gyeonggi-do, and H nursery school located in Hwaseong-si, Gyeonggi-do, were divided into 18 experimental groups and 18 people from comparison group and pre-post analysis was conducted. The research tool analyzed the data collected using the nutrition knowledge measuring tool and the eating habits measuring tool using the program SPSS, and the analysis method was conducted with t-test(verification) to verify the homogeneity of the experimental group and the comparative group. Analysis result, first. Infants aged 3 to 4 in experimental groups who have experienced vegetable gardening activities have higher nutritional knowledge than infants in comparison groups. In the case of nutrition knowledge, there was no statistically significant difference between the experimental group and the comparative group before the vegetable gardening activities were carried out. But after the experimental treatment, the experimental group showed statistically significant differences in improving the concept of nutritional knowledge (the reason for eating food, the type and function of food, hygiene, and garden) in the post-examination of the comparative group. Second, it can be seen that infants aged 3 to 4 in experimental groups who experienced vegetable gardening activities showed significant differences in table manners and eating behavior among sub-factors of eating habits compared to infants in comparison groups who had never experienced them. In conclusion, vegetable gardening activities are educationally useful in terms of expecting positive changes in the nutrition knowledge and eating habits formation of infants.

This study focuses on the 'invention technique and practical experience' unit to observe how the colleague mentoring class has its effect on self-efficacy. For this, we have selected experimental group and comparative group and proceeded the experiment. For five classroom hours of the 'technique of invention and practical experience' unit, each group was assigned different method to do the experiment. The experimental group was applied with the colleague mentoring method and the comparative group was applied with the self study method. To observe the differences of how it effects on one's self-efficacy, the questionnaire was distributed before and after class. Then, it was verified for the meaningful differences between the two groups. To summarize, the results are as follows. First, for self-efficacy experiment, the questionnaire before the experiment showed that there were no differences found between two groups. However, the questionnaire collected after the experiment showed great differences. The group with the colleague mentoring showed more meaningful differences at p<.05 significance level than comparative group. Furthermore, by observing the before and after questionnaire, it was found that both groups showed statistically meaningful differences at p<.05 significance level, but the experimental group showed greater self-efficacy improvements than comparative group. Second, when further examining the self-efficacy, the activity start expectation, activity continuation expectation, activity performance expectation, and experience recovery expectation showed the statistically meaningful differences at p<.05 significance level. According to the above results, it can be stated that the colleague mentoring class has more positive effects on the self-efficacy than self-study class. Summing up, the colleague mentoring class is more effective than self-study for fostering student's self-efficacy.
