Not only can air pollution reduce the overall competitiveness of tourist destinations, but also changes tourists' travel decisions, thereby affecting the tourism flows. The study presents a machine learning method to analyze how the haze pollution puts spatial effect on tourism flows in China from 2001 to 2018, and reveals the regional differences in heterogeneity among eastern, central, and western China. Our investigation reveals three interesting observations. First, the Environmental Kuznets Curve of the impact of haze pollution on tourism flows is not significant. In the eastern and western regions, the interaction between haze pollution and domestic tourism flows as well as inbound tourism flows shows an inverted U-shaped curve respectively. Second, there is an significantly positive spillover effect of tourism flows in all of the eastern, central, and western regions. As to the intensity of spillover, domestic tourism flows is higher than that of the inbound tourism flows. Both of the above figures are greatest in the eastern. Third, the Chinese haze pollution mainly reduces the inbound tourism flows, and only imposes significantly negative direct effects on the domestic tourism flows in the central region. In the central and eastern regions, significantly negative direct effects and spillover effects are exerted on inbound tourism.

This study aimed at identifying the characteristics of current science curriculum in several countries in terms of its format, aims and objectives, contents and guidelines and discussed about therm. The curricula were collected from 9 countries- The United States of America(5 states), Canada(4 Provinces), England, West Germany, France, Australia, Newzealand, Japan and the republic of China. Each country had her own characteristics of science curriculum, but there also common characteristics among several countries. First, the format of science curricula in eastern countries were very different from those of western countries. The western countries had the curriculum format which included characteristics and needs of science education, philosophy and background, aims and objectives, contents, characteristics of learners, teaching and learning strategy, teaching materials, guide of experiments, evaluation methods, and other concrete informations while eastern countries had the curriculum format which included only objectives, contents and guidelines. I think that the format of science curriculum in western countries is more recommendable than that of eastern countries. Second, the aims and objectives of science curricula in eastern countries focused on scientific knowledges and concepts, while those of countries emphasized scientific methods and attitudes. Third, the contents of science curricula were very similar regardless of eastern countries or western countries. In other words, all the countries in this study emphasized life science and earth science at lower grade level and physical science at upper grade level. Especially the observation and concrete learning activities were suggested at lower grade level and logical reasoning was emphasized at upper grade level. I think that the integrated (topic-centered) science curriculum is more recommendable than our current non-integrated science curriculum in lower grade levels. Finally, the guidelines of science curriculum in eastern countries did not suggest specific information about teaching contents, experimental methods, teaching-learning activities, evaluation methods, teaching and learning meterals, while those of western countries provided more specific information which teachers could utilize very effectively.

수운이 해월에게 도통을 전수(傳授)한 때로 알려진 1863년 7~8월에 관한 기록 중 가장 앞선 것으로 평가되는 문헌은 『수운문집(水雲文集)』, 『대선생주문집(大先生主文集)』, 『최선생문집도원기서(崔先生文集道源記書)』(이하 『도원기서』)이다. 이 세 문헌의 수운 관련 기록은 구조, 내용, 기술 방식으로 본다면 같은 문헌에서 기원했음이 분명하다. 세 문헌이 지닌 차이는 어느 문헌이 도통전수의 실상을 정확히 반영하고 있는지에 대한 논쟁을 초래했으며 신앙과 조직 체계 등 초기 동학의 성격에 대한 재검토의 필요성을 환기하고 있다. 따라서 세 문헌을 고증하여 각 문헌의 선후 관계와 성립연대, 정확성, 기술 방향, 문헌에 반영된 초기 동학 신앙체계의 특징을 밝혀낼 수 있다면 1860~1880년의 동학 전개 과정을 보다 명확히 기술할 수 있으며 여러 도통전수 담론이 지닌 의미를 보다 깊이 분석할 수 있다. 세 문헌을 비교하고 관련 문헌과 대조하여 고증한 결과, 해월의 도통전수 사건이 기록되지 않은 『수운문집(水雲文集)』 계통의 문헌이 이를 명확히 기록한 『대선생주문집(大先生主文集)』과 『도원기서』의 저본일 가능성이 크다는 사실을 확인했다. 이는 『대선생주문집(大先生主文集)』과 『도원기서』가 편찬되는 시기까지 해월의 도통전수는 동학 교단 내외에서 명확하게 인정받지 못했다는 것을 뜻한다. 해월의 연원이 동학의 최대 조직이 된 1870년대 후반에 이르러서야 해월을 중심으로 동학의 교리가 재해석되고 조직이 재건되었다는 사실을 통해서도 이는 방증 된다. 따라서 해월의 도통전수를 역사적 사실이라기보다는 하나의 담론으로 보는 관점에서 수운 이후의 동학은 조망될 필요가 있다. 이는 '수운의 동학'과는 단층을 이루는 '해월의 동학', 그리고 해월과 한국의 근대 신종교 운동의 관계를 새로운 관점에서 볼 수 있도록 해줄 것이다.

Mobile devices have become attractive learning devices for education. The digitalization of the higher education system in Sri Lanka by 2020 is part of the government's effort to modernize and enhance the country's overall education system particularly in view of the COVID-19 pandemic. Theoretically, this study contributes to the M-Learning model in higher education institutions via the integration of literature on technology adoption (TAM and UTAUT) with the variables of Perceived Usefulness, Perceived Ease of Use, Attitude, Effort Expectancy, Social Influence, and Facilitating Condition. The attitude towards M-Learning amongst higher education students was gauged via an online questionnaire survey. The convenience sample comprised 344 students from the Advanced Technological Institutes (ATI) in Batticaloa District, Sri Lanka. Descriptive statistics, a measurement, and structural model, and hypotheses testing were used to analyze the derived data. The findings indicate that mobile learning is significantly affected by perceived ease of use, social influence, effort expectancy, and facilitating condition, but negatively affected by attitude and perceived usefulness. The exhaustive literature review revealed that there are very few M-Learning studies related to digital learning in the context of higher education in the Batticaloa district.

The purpose of this study is to develop a human activity recognition (HAR) system, which distinguishes 13 activities, including five activities commonly dealt with in conventional HAR researches and eight activities from the Eastern-Asian culture. The eight special activities include floor-sitting/standing, chair-sitting/standing, floor-lying/up, and bed-lying/up. We used a 3-axis accelerometer sensor on the wrist for data collection and designed a machine learning model for the activity classification. Data clustering through preprocessing and feature extraction/reduction is performed. We then tested six machine learning algorithms for recognition accuracy comparison. As a result, we have achieved an average accuracy of 99.7% for the 13 activities. This result is far better than the average accuracy of current HAR researches based on a smartwatch (89.4%). The superiority of the HAR system developed in this study is proven because we have achieved 98.7% accuracy with publically available 'pamap2' dataset of 12 activities, whose conventionally met the best accuracy is 96.6%.

Rainfall-Runoff modeling plays a crucial role in various aspects of water resource management. It helps significantly in resolving the issues related to flood control, protection of agricultural lands, etc. Various Machine learning and statistical-based algorithms have been used for this purpose. These techniques resulted in outcomes with an acceptable rate of success. One of the pertinent machine learning algorithms namely Adaptive Neuro Fuzzy Inference System (ANFIS) has been reported to be a very effective tool for the purpose. However, the computational complexity of ANFIS is a major hindrance in its application. In this paper, we resolved this problem of ANFIS by incorporating one of the evolutionary algorithms known as Particle Swarm Optimization (PSO) which was used in estimating the parameters pertaining to ANFIS. The results of the modified ANFIS were found to be satisfactory. The performance of this modified ANFIS is then compared with conventional ANFIS and another popular statistical modeling technique namely ARIMA model with respect to the forecasting of runoff. In the present investigation, it was found that proposed PSO-ANFIS performed better than ARIMA and conventional ANFIS with respect to the prediction accuracy of runoff.

This study's aim is to identify modern and post-modern values and transnationalism embodied in Daesoon Thought and to seek for the new value to overcome irrationality of modern values in this society we live in. Several previous studies discussed about these issues, but most of them studied them on the basis of Korean new religions or Jeungsangyo, or in sociological theory perspective. Therefore, this study focused on Daesoon Thought encompassing ideological perspective as well as historical perspective of Daesoonjinrihoe. As for nationalism, while Eastern learning(Dong-Hak) is prone to ethnocentricity, Daesoon Thought shows trans-ethnic perspective. As for historical perspectivel, Mugeuikdo, a precursor to Daesoonjinrihoe showed non-relationship with any politics as contrasted with other new korean religious movement at that time. As for aspects of modern values, 3 perspectives (political system, social system, abolition of premodern values) were discussed. As for political system perspective, while Eastern learning advocates democratic modernity but accepted monarchy, Jeungsan denied monarchy. And While western political philosophy advocated rationality-based absolute person, Daesoon Thought proposes ideal human who can have political power and do religious indoctrination all together. As for social system perspective, while western humanism is based on all of he people's equity in front of God, Eastern learning on humans are Heaven (人乃天), Daesoon Thought is based on Injon thought(人尊思想) which encompasses spiritual world, human world and all of the universe. Daesoon Thought also proposes abolition of discrimination by gender, social position. As for abolition of premodern values, Daesoon Thought critics pre-modern formalism and advocate acceptance of other nations' culture, pragmatism, and humanism. As presented above, Daesoon Thought has not only modern values but also aspects of post-modernity and transnationalism. In the future, further studies are needed which tackle these issues and search for new values of Daesoon Thought which can overcome limitation of modern values.

This study explored teachers (n = 219) from northern, central, southern and eastern Taiwan concerning their views about children's learning difficulties, mathematical instruction and school mathematics curricular. Results showed that teachers' mathematics knowledge or their instruction methods had no significant influence on their views of children's learning difficulties. Even though teachers indicated that understanding of abstract mathematical concepts was the most prominent difficulty for children, they tended to employ direct instruction rather than constructive and cooperative problem solving in their teaching. However, teachers' views of children's learning difficulties did influence their instructional practice. Results from in-dept interviews revealed that there were some obstacles that prevented teachers from putting constructiveism perspectives of instruction into teaching practice. Further investigation is needed to develop a better understanding of epistemology and teaming psychology as well as to help teachers create constructive learning situations.
