Purpose: The 'learning cycle' proposed by Guilbert in 1981 has been accredited as an effective and useful model for curriculum design. Three components of learning cycle, learning objective, instructional method, and assessment are connected organically and form basic structure of curriculum. In this study, we intend to analyze how the learning cycle and its three components are applied to present medical curriculum and examine the points at issue of the learning cycle in medical education. Also, we try to identify the educational significance of the leaning cycle in medical education. Results: First, concerning the learning objective, it was identified that impractical and abstract expressions are major controversial points. Also, there is a need to make learning objectives covering entire medical curriculum. Second, because of various structural problems, it is hard to practice new and various instructional methods. Third, even though there is a growing need for medical curriculum to develop and utilize more various and detailed assessment and evaluation, it was revealed that only are standardized and traditional assessments mainly used. Conclusion: Synthetically, we have some suggestions as follows. First, it is necessary to specify and actualize the learning objectives. Also, instructional methods and assessments should be diversified. And finally, there is a need to build organic and delicate medical curriculum by applying the learning cycle to medical education more actively.

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.

This study examined the effects of the learning cycle model by learner's characteristics such as I.Q., cognitive levels, inquiry skins, cognitive style, activity, reflectiveness. To see the effects of the learning cycle model, nonequivalent control group pretest-posttest multiple treatment designs was used in the study. 99 middle school second-graders(female) were divided into two groups. One group was selected as the experimental group (n=50), the other served at the comparison group(n=49). During the eight-month period, the students in the experimental group were instructed according to the learning cycle model, while the students in the comparison group were instructed according to the traditional instruction methods. Achievement data from science achievement test were analyzed by an ANOVA technique. The results of the study are as follows : 1. Science knowledge achievement. For the lower level students of activity, the learning cycle model is superior to the traditional approaches in science knowledge achievement. 2. Science inquiry skills. For the upper level students of I.Q., cognitive levels, inquiry skills, cognitive style and reflectiveness, the learning cycle model is superior to the traditional approaches in science inquiry skills. 3. Attitudes toward science. For the lower level students of I.Q., cognitive levels, inquiry skills, cognitive style, activity and reflectiveness, the learning cycle model is superior to the traditional approaches in attitudes toward science.

Purpose: This study presents a research approach that utilizes deep reinforcement learning to construct optimal portfolios based on the business cycle for stocks and other assets. The objective is to develop effective investment strategies that adapt to the varying returns of assets in accordance with the business cycle. Methods: In this study, a diverse set of time series data, including stocks, is collected and utilized to train a deep reinforcement learning model. The proposed approach optimizes asset allocation based on the business cycle, particularly by gathering data for different states such as prosperity, recession, depression, and recovery and constructing portfolios optimized for each phase. Results: Experimental results confirm the effectiveness of the proposed deep reinforcement learning-based approach in constructing optimal portfolios tailored to the business cycle. The utility of optimizing portfolio investment strategies for each phase of the business cycle is demonstrated. Conclusion: This paper contributes to the construction of optimal portfolios based on the business cycle using a deep reinforcement learning approach, providing investors with effective investment strategies that simultaneously seek stability and profitability. As a result, investors can adopt stable and profitable investment strategies that adapt to business cycle volatility.

This aim of this study was to investigate the effects of the music appreciation teaching-learning method on the musical ability of young children. The music appreciation activities were developed firstly in consideration of the 4 steps of the learning cycle (recognition, exploration, inquiry, application). One group was then taught music appreciation, taking into account the learning cycle. The results were then compared with another comparative group in terms of musical ability. The results indicated that the musical ability sum of the treatment groups improved more than the comparative group. More specifically, the treatment group for four-year-olds was seen to have improved significantly more than the comparative group in terms of musical ability. These results indicate that this music appreciation teaching-learning method has a number of positive effects upon young children`s musical ability. Therefore, it is suggested that kindergarten teachers conduct instruction with an appropriate accompanying learning cycle as part of the teaching-learning method when it comes to improving the musical ability of young children.

The estimation of radio map (RM) is a fundamental and critical task for the network planning and optimization performance of mobile communication. In this paper, a RM estimation method is proposed based on a deep dual learning structure. This method can simultaneously and accurately reconstruct the urban building map (UBM) and estimate the RM of the whole cell by only part of the measured reference signal receiving power (RSRP). Our proposed method implements UBM reconstruction task and RM estimation task by constructing a dual U-Net-based structure, which is named RadioCycle. RadioCycle jointly trains two symmetric generators of the dual structure. Further, to solve the problem of interference negative transfer in generators trained jointly for two different tasks, RadioCycle introduces a dynamic weighted averaging method to dynamically balance the learning rate of these two generators in the joint training. Eventually, the experiments demonstrate that on the UBM reconstruction task, RadioCycle achieves an F1 score of 0.950, and on the RM estimation task, RadioCycle achieves a root mean square error of 0.069. Therefore, RadioCycle can estimate both the RM and the UBM in a cell with measured RSRP for only 20% of the whole cell.

The purpose of this study was to introduce the concepts of experiential learning and the Kolb's model, and to review some applications of experiential learning theory in graduate medical education. The published literature on GME and education for general practitioners applying the experiential theory and the Kolb's model was reviewed. Experience learning defined the cyclical learning process which emphasizes the learners' reflective thinking of the learners' concrete experiences and their active participation in continuous learning actives. Kolb includes this 'cycle of learning' as a central principle in his experiential learning theory. This is typically expressed as a four-stage cycle of learning. Kolb's cycle moves through concrete experience(CE), reflective observation(RO), abstract conceptualization(AC) and active experimentation(AE). Components of continuing education of the adult learner were based on autonomy, context of learning, and competence and performance as educational objectives. Some strategies for graduate medical education were reflective thinking, self-directed learning, morning reporting and feedback with peer review, etc. Opportunities for learning from experience in practical life can be made to enhance reflective thinking and performance of practitioners. Strategies to develop reflective practice among physicians should be explored by further research.
