This research aims to figure out the impact of different reflective thinking methods on pre-service geography teachers' teaching knowledge. Four pre-service teachers in the same level were selected through the first simulated instruction, Then, different reflective methods were given them to carry out the reflection. Afterwards, they carried out their second simulated instruction. The change of average score of pre-service teachers was analyzed through the peer reviews and Paired samples T-test. The results are as follows. First, when the first peer review score were compared with second peer review, average score of all pre-service teachers improved. But, pre-service teachers who got cooperative reflection with a specialist had the widest variation in the increase level of average score comparing to those without reflection or reflective journal writing. Second, reflective journal writing through self-reflection led to their reflective thinking, but it did not induce them to reflective practice. Finally, pre-service teacher who got cooperative reflection with experienced teachers got the significant improvement in PCK through the T-test. In particular, it had significant statistical value in instruction section and understanding of students section. It demonstrates that the contextual section could be improved by self-reflection or repetitive class practices, while instruction section and understanding of students section needed consulting by assistants.

Purpose: To compare the clinical and radiological results of anterior cruciate ligament(ACL) reconstruction using hamstring autograft and tibialis tendon allograft. Materials and Methods: Twenty four ACL reconstructions using hamstring autograft and 30 using tibialis anterior tendon altograft were followed up at least 1 year. We performed femoral tunnel fixation with Ligament Anchor(LA) screw and tibial tunnel fixation with biodegradable interference screw. Evaluations included Lysholm knee(LK) score, Tegner activity scale, Lachman test, Pivot-Shift test, Quardriceps atrophy, incision site numbness, anterior knee pain and instrumented anterior laxity with $Telos^{(R)}$ device. Results: Preoperativ mean LK score was $60.3(18{\sim}82)$ in autograft group and 61.2(25-80) in allograft group. Mean LK score improved to $91.6(68{\sim}100)\;and\;92.6(77{\sim}100)$ respectively. Activity level, using Tegner activity scale, slightly decreased compared with that of Preinjury state in both groups. Lachman test, pivot-shift test, Quadriceps atrophy, anterior knee pain, incision site numbness, and anterior drawer test using $Telos^{(R)}$ device showed no significant difference between two groups (p>0.05). Conclusion: In performing the ACL reconstruction, there was no statistically significant difference between hamstring autograft group and tibilis anterior allograft group in clinical or in radiological results.

This study tries to analyze whether the Earned Income Tax Credit (EITC), which was modified in 2011, has the effect of work incentive. In this sense, by establishing the 8th Wave of Korea Welfare Panel Study (2013) and the 9th Wave (2014), Furthermore, in order to overcome the methodological limit, the results of two-party analysis method will be compared by firstly carrying out multiple regression analysis and then performing propensity score matching analysis. The 535 households out of 6,025 were selected. The following are the results of multiple digression analysis and propensity score matching analysis. First, there was no statistically meaningful relationship with regard to the perception of the EITC. Second, there was a statistically meaningful result in the reduction of working hours with regard to whether a household received labor incentive or not. The study found that the revised EITC is not providing incentives which stimulates the will to work.

In this paper, I analyzed the cause that girl' ICT literacy score was hiegher than boy's score in middle school after 2010. KERIS had sampled 1% of whole middle school students and measured their ICT level. Therefore, I analyzed the correlation by gender between ICT literacy score and the using habit of ICT based on that result. As a result, the girl's score was higher than the boy's score in field of creating or editing documents, searching information for homework and study, accessing to on-line dictionary for study and enjoying SNS. Also, that difference between girl and boy had little correlation with ICT literacy score. Therefore, I proposed educational method for ICT literacy learning based on the difference of habit to use ICT between boys and girls.

Geriatric depression is associated with pathological changes in the brain and increases the risk of cognitive impairment or dementia. However, high cognitive reserve, such as high education, can delay or minimize clinical manifestations of pathologies involving the brain, so the effect of geriatric depression on cognitive impairment or dementia may vary depending on the education level. In this study, the author analyzed data from the Korean Longitudinal Study of Aging (KLoSA) to examine whether the effect of geriatric depression on cognitive function differed depending on education level. Among the 10,254 subjects registered in the KLoSA, the 4,905 subjects who met the inclusion criteria were analyzed by stepwise regression analysis. The results were as follows: first, depressive symptoms predicted low cognitive function after 12 years; second, the negative effect of depressive symptoms on cognitive function after 12 years was higher in the old adult group than in the young adult group; and third, the effect of age was significant only in the low-educated group. These results suggest that depressive symptoms in low-educated old adults may increase the risk of development of dementia in the long term.

This study was conducted to compare the evaluation scores among different evaluation agents-tutor, peer and self evaluation. It also aimed to identify the correlations among the evaluation agents and each agent's influencing factors that can have impact on PBL evaluation. 105 nursing students who had PBL methods in their learning had 3 different tutor, peer and self evaluation consecutively with the PBL Effectiveness Evaluation Tool. Self evaluation score was higher than both tutor and peer evaluation for 3 different evaluation. There was a significant correlation between tutor evaluation and peer evaluation. 'Problem solving ability' for tutor evaluation and 'Cooperative learning ability' for peer evaluation and self evaluation were the influencing factors.

This study confirmed the validity of the health score(HS) calculation methodology and results. HS is an index that scores the degree of personal health by applying clinical standards and statistical function to health check-up items. It's calculated by the total size of the biomarker on the health change, the influence on the health change, the weight change rate according to the degree of outlier, and the standardized value. In order to confirm the validity of the results, several diseases were selected and HS was compared between the disease occurrence group and the disease absence group. And by segmenting the ranked HS, the disease incidence rate was compared. As a result, in all selected diseases, the difference in the mean of HS was significant according to the presence or absence of disease, and the incidence of selected diseases showed a tendency to increase as HS decreased.

Local drought in South Korea has recently increased interest in the efficient use of groundwater and then induces a growing need to introduce artificial recharge of groundwater that stores water in sedimentary layer. In order to evaluate the potential artificial recharge sites in the alluvial basins in Chungcheongnamdo province, an AHP (Analytical hierarchy process) model consisting of three primary and seven secondary factors was developed in this study. In the AHP model, adding candidate sites changes final evaluation score through a mathematical calculation process. By contrast ANN (Artificial neural network) model always provides an unchanged score for each candidate area. Therefore, the score can be used as a selection criterion for artificial recharge sites. It is concluded that the possibility of artificial recharge is relatively low if the score of the ANN model is less than about 1.5. Further studies and field surveys on the other regions in Korea will lead to draw out a more applicable ANN model.
