  • In this study, it was conducted a broad-area landslide analysis for the entire area of Kyungsangbuk-do Province based on spatially-distributed wetness index and root reinforcement infinity slope stability theory. Specifically, digital map, soil map and forest map were used to extract topological and geological parameters, and to build spatially-distributed database at $10m{\times}10m$ resolution. Infinity flow direction method was used for rain catchment area to produce spatially-distributed wetness index. The safety level that indicates risk of a broad-area landslide was classified into four groups. The result showed that areas with a high estimated risk of a landslide coincided with areas that recently went through an actual landslide, including Bonghwa and Gimcheon, and unstable areas were clustered around mountainous areas. A comparison between the estimation result and the records of actual landslide showed that the analysis model is effective for estimating a risk of a broad-area landslide based on accumulation of reasonable parameters.

  • The purpose of this study is to examine the effects of team efficacy and perceived loafing on learning outcome in team-based project learning. For this purpose, questionnaire survey was conducted to 58 students who enrolled the adolescent welfare class in 2019 at H University. A hierarchical regression analysis was conducted for the effects of team efficacy and perceived loafing on learning outcomes and the interaction effect between two variables. Main results of this study were as follows. Team efficacy had a positive effect on learning outcomes. Second, perceived loafing did not have a statistically significant effect on learning outcomes. Third, the interaction effect of perceived loafing and team efficacy on learning outcomes was significant. In particular, the negative effect of perceived loafing on learning outcomes was reduced by team efficacy. Based on the research results, a plan to increase the learning outcome of team-based project learning was discussed.

  • 1997년 아시아에 재정 위기가 닥치면서 태국의 비료 산업이 크게 타격을 입었으며 최근 몇 년 동안 그 회복이 빠르게 진행되지 않고 있다. 그러나 여기 David Hayes에 의하면, 비료 소비와 시장가격 그리고 국내 비료산업의 이익률이 결국에는 튼튼한 기초 위에 다시 되돌아 올 것이라는 희망이 주요 수출 부문에서 일고 있어 이러한 희망으로 인해 새로운 자본 유입이 태국의 농업과 가공 식품산업을 목표로 하여 합작이 이루어졌다고 했다.

  • Purpose: Most of the studies in the country on earthquake-induced landslide predict the displacement of the slope. Until now, no studies have been conducted on the occurrence of landslides and damage characteristics by earthquakes. Therefore, this study was conducted to obtain basic data of landslides caused by earthquakes. Method: In order to analyze the characteristics of earthquake-causing landslides, we have collected data reported in the media over the past decade. Landslides in foreign countries were analyzed separately by cause of occurrences such as rainfall and earthquake. Landslides from abroad were analyzed according to the cause of the occurrence, and landslides caused by earthquakes were further analyzed as follows: the magnitude of an earthquake, year of occurrence, number of occurrences by continent, damage status, etc. Result: In the past 10 years, a total of 608 landslides have been reported from overseas, and the cause is the highest with 340 landslides due to rainfall. There were 70 cases of landslides caused by earthquakes, and it was analyzed as the second cause of landslides. The average magnitude for earthquakes that caused landslides was 6.5, and the minimum and maximum magnitude were 4.4 and 8.2 respectively. The earthquake-induced landslides were the most occurrence in 2011yr and 2012yr, and the continent was the most common in Asia. Also, It was analyzed that if an earthquake caused landslides, the number of casualties increased and the size of the damage increased. Conclusion: Currently, earthquakes are steadily increasing in Korea, and the possibility of strong earthquakes is also increasing. Earthquake-induced landslides are beyond human control due to natural disasters but can minimize damage through active prevention and response. It is expected that the results of this study will be used as basic data in establishing measures for earthquake landslides to reduce property and human damage in the future.

  • Purpose: In this study, earthquake-induced landslide risk assessment was conducted to provide basic data for efficient and preemptive damage prevention by selecting the erosion control work before the earthquake and the prediction and restoration priorities of the damaged area after the earthquake. Method: The study analyzed the previous studies abroad to examine the evaluation methodology and to derive the evaluation factors, and examine the utilization of the landslide hazard map currently used in Korea. In addition, the earthquake-induced landslide hazard map was also established on a pilot basis based on the fault zone and epicenter of Pohang using seismic attenuation. Result: The earthquake-induced landslide risk assessment study showed that China ranked 44%, Italy 16%, the U.S. 15%, Japan 10%, and Taiwan 8%. As for the evaluation method, the statistical model was the most common at 59%, and the physical model was found at 23%. The factors frequently used in the statistical model were altitude, distance from the fault, gradient, slope aspect, country rock, and topographic curvature. Since Korea's landslide hazard map reflects topography, geology, and forest floor conditions, it has been shown that it is reasonable to evaluate the risk of earthquake-induced landslides using it. As a result of evaluating the risk of landslides based on the fault zone and epicenter in the Pohang area, the risk grade was changed to reflect the impact of the earthquake. Conclusion: It is effective to use the landslide hazard map to evaluate the risk of earthquake-induced landslides at the regional scale. The risk map based on the fault zone is effective when used in the selection of a target site for preventive erosion control work to prevent damage from earthquake-induced landslides. In addition, the risk map based on the epicenter can be used for efficient follow-up management in order to prioritize damage prevention measures, such as to investigate the current status of landslide damage after an earthquake, or to restore the damaged area.

  • 본 논문에서는 로봇 프로그래밍 교육을 통하여 예비 교사의 로봇에 대한 태도 변화를 살펴보았다. 로봇 프로그래밍 교육의 예비 교사의 로봇에 대한 태도에 미치는 영향을 살펴보기 위하여, ICT 교육을 받는 예비 교사와 프로그래밍 교육을 받는 예비 교사와 로봇에 대한 태도를 비교하였다. 비교를 통하여, ICT 교육을 받은 예비 교사와 프로그래밍 교육을 받은 예비 교사는 로봇에 대한 태도 변화가 없는 것을 확인할 수 있었다. 하지만 로봇 프로그래밍 교육을 받은 예비 교사들은 로봇에 대한 태도가 통계적으로 유의미한 변화가 나타났다. 또한, 예비 교사에게서 나타난 로봇에 대한 태도 변화는 로봇에 대한 부정적인 태도가 긍정적으로 바뀌는 데 영향을 준 것을 확인할 수 있었다. 이러한 결과를 통하여 로봇 프로그래밍 교육이 예비 교사의 로봇에 대한 태도를 긍정적으로 바꾸는 데 영향을 준다는 결론을 얻을 수 있었다.
