This paper investigates the comparative effectiveness of two kinds of instructional methods in transfer of mathematics learning: one based on the situated cognition, ie. situated learning and the other based on traditional learning. Two classes of second graders studied the instruction about 3-digit addition and subtraction. After that, they completed two written tests and a real situation test. As a result. no significant differences were found between the two group's performance on the written test 1 and real situation test. But the situated learning group performed significantly better on the performance of story problem than traditional group. This result indicated that the situated learning made improvement in transfer of mathematic loaming. As a result of interviews with 12 children, the situated loaming group's children were able to use contextual resources in solving real situation as well as story problems.

Corrosion detection and analysis is a very important topic in reducing costs and preventing disasters. Recently, image processing techniques have been widely applied to corrosion identification and analysis. In this work, we briefly introduces traditional image processing techniques and machine learning algorithms applied to detect or analyze corrosion in various fields. Recently, machine learning, especially CNN-based algorithms, have been widely applied to corrosion detection. Additionally, research on applying machine learning to region segmentation is very actively underway. The corrosion is reddish and brown in color and has a very irregular shape, so a combination of techniques that consider color and texture, various mathematical techniques, and machine learning algorithms are used to detect and analyze corrosion. We present examples of the application of traditional image processing techniques and machine learning to corrosion detection and analysis.

This paper attempts to explore the need and importance of values integration in educational activities to mitigate learning crisis and promote sustainable learning achievement. The traditional approach, commercial motive, focus on instrumental knowledge coupled with many other contemporary issues have collectively smothered the fundamental humanistic principles of education. To avert the situation and execute the core objectives, we need to shift our focus: a shift from instrumental knowledge to humanistic-transformational knowledge; a shift from the traditional approach of supplying and storing information to learning to deal with the real-world problems; a shift from head to heart. Values integration is an attempt to initiate and promote this shift. Rather than teaching values and moral principles under a particular subject heading, values need to be a part of everyday in-school and out-school activities. To concretize this concept, a model is proposed in this study as a holistic model of values integration via whole school ambiances and community support.

과학교육에 있어 지금까지 개발된 수업모형은 마치 과학의 모든 목적을 달성시켜줄 것 같지만 실제 교육현장에 적용해 보면 기대하던 효과를 얻지 못하는 경우가 많다. 수업의 효과를 극대화하기 위해서는, 어느 한가지 방법만을 고수하는 것보다 개발된 수업모형을 유연성 있게 활용 할 수 있는 교사의 수업전략이 필요하다. 본 연구는 개념도와 순환학습을 통합한 수업이 개념도를 활용한 수업이나 순환학습과 비교하여 고등학생들의 학업성취도 및 과학적 탐구능력, 과학에 대한 태도에 어떠한 영향을 주는지 알아보는데 그 목적이 있다. 연구대상은 고등학교 2학년 여학생 324명으로, 개념도-순환학습 집단, 개념도 활용 집단, 순환학습 집단, 전통적 수업 집단의 4집단으로 나누어 수업하였다. 연구 단원은 고등학교 과학의 '생식과 유전' 단원으로 약 10주간 10차시에 걸쳐 수업처치 하였다. 수업처치 전, 후에 학업성취도 검사와 과학적 탐구능력, 과학에 대한 태도 검사를 실시하였고, 연구결과는 공변량 분석 (ANCOVA과)과 사후 검증(Duncan test)으로 분석하였다. 개념도-순환학습은 학생들의 과학 학업성취도를 향상시키는데 전통적인 수업보다 효과적이었고(p< .05) 그 효과면에서 개념도를 활용한 수업보다 떨어지지 않았다. 성취 수준이 상위와 중위 학생들은 수업방법에 따라 학업성취도에 차이를 보이지 않았으나, 하위학생들은 개념도를 활용한 수업이 가장 효과적이었다(p< .05). 개념도-순환학습은 학생들의 과학적 탐구능력을 신장시키는데 개념도를 활용한 수업이나 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 순환학에 떨어지지 않았다. 성취수준이 상위인 학생은 수업방식에 따라 과학적 탐구능력에 차이를 보이지 않았으나, 개념도-순환 학습은 중위와 하위 학생들의 과학탐구능력 향상에 순환학습 만큼 효과적이었다. 개념도-순환학습은 학생들의 과학에 대한 태도를 향상시키는데 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 개념도 활용 학습이나 순환학습에 뒤지지 않았다. 따라서 개념도 순환 학습은 모든 학생들의 수준을 고려 할 때 학생들의 학업성취도를 향상시키고, 과학적 탐구능력을 신장시키는데 개념도 활용학습이나 순환학습을 단독으로 적용하는 것보다 긍정적이라고 할 수 있다.

The goal of this study was to understand the reasons for learning about Korean herbal food by examining the actual conditions in a Korean herbal food course during lifestyle education. The general characteristics of the people learning about or working with the food as well as the correlations between the examined factors were analyzed, focusing on each person's dietary lifestyle. We divided the class participants into five dietary lifestyle groups by analyzing their scores. Group 1 was the"taste-seeking type", group 2 was the "quality-seeking type", group 3 was the"economy-seeking type", group 4 was the"convenience and economy-seeking type", and group 5 was the"convenience and health-seeking type". A person with a cooking career was considered to have more experience with Korean herbal food. The highest motivation for Korean herbal food education was for professional reasons, and the class that was most appreciated was learning about Korean traditional herbal foods. The highest satisfaction for the class was based on the instructor's knowledge, followed by food tastes, foodstuffs, educational materials, and the facilities superintendent. Satisfaction with the class tuition and practical utilization was relatively low.

Traditional wooden buildings deform over time and are vulnerable to fire or earthquakes. Therefore, traditional wooden buildings require continuous management and repair, and securing architectural drawings is essential for repair and restoration. Unlike modernized CAD drawings, traditional wooden building drawings scan and store hand-drawn drawings, and in this process, many noise is included due to damage to the drawing itself. These drawings are digitized, but their utilization is poor due to noise. Difficulties in systematic management of traditional wooden buildings are increasing. Noise removal by existing algorithms has limited drawings that can be applied according to noise characteristics and the performance is not uniform. This study presents deep artificial neural network based noised reduction for architectural drawings. Front/side elevation drawings, floor plans, detail drawings of Korean wooden treasure buildings were considered. First, the noise properties of the architectural drawings were learned with both a cycle generative model and heuristic image fusion methods. Consequently, a noise reduction network was trained through supervised learning using training sets prepared using the noise models. The proposed method provided effective removal of noise without deteriorating fine lines in the architectural drawings and it showed good performance for various noise types.

Purpose: The purpose of this study was conducted to evaluate the effects of an action learning-based nursing ethics education on the self-assertiveness and ethical values in nursing students. Methods: The study was a non-equivalent control group pretest-posttest design. This study was carried out from October 19 to December 11, 2015. Participants were fifty-six undergraduate nursing students who assigned to either an action learning-based nursing ethics education or traditional lecture. Outcomes were measured assessed self-assertiveness and ethical values using questionnaires. Results: There was a significant improvement in the self-assertiveness in the experimental group who received an action learning-based nursing ethics education than the control group who undertook the traditional lecture (p=.017). However, ethical values were not statistically signigicant between two groups (p=.347). Conclusion: This study demonstrated that an action learning-based nursing ethics education for undergraduate students is very effective in promoting self-assertiveness compared to the traditional lecture.
