Penggunaan Media Kartu Bergambar Dalam Pengembangan Materi Ajar Buku Hanyu Tingli Jiaocheng Untuk Mata Kuliah Menyimak I Dan II Bahasa Mandarin

This research focused on the study on the development of teaching materials using the instructional media card with a picture in a book “Hanyu Tingli Jiaocheng” especially vocabulary as supporting the learning process. The choosing of appropriate learning media supported the teaching-learning process. The choosing of the media must be done carefully using many considerations to achieve the target of learning in facilitating the learners. This research was conducted on the Mandarin Listening I and II. Approproate teaching materials are needed to support teachers who teach this course. This study used qualitative research. The research was done in the Basic Class I and Basic Class II. The result showed that the Mandarin students got new concept for Mandarin learning process

The River God Cult and the Reshaping of Political Authority—Reading Inscriptions from the Hezhong Area in Tang China

The River God cult held a significant place in state rituals in imperial China. While scholars have primarily focused on the evolution of the River God sacrificial system, with its interplay of the official granting of noble titles and popular beliefs, this paper offers a further examination of the River God cult. By reading the “Stele of the (Shrine) Temple for the River God honored as the Duke of Numinous Source” (hedushen lingyuangong cimiao bei 河瀆神靈源公祠廟碑), created in the Tang Dynasty, this study explores the interactive relationship between the River God cult and state power in the Hezhong 河中area during that time period. We contend that the traditional River God cult and the participation of both officials and civilians in common rituals throughout past dynasties not only created a concentration of historical memories and reverent emotions but also established a strong social foundation for belief in the River God within the Hezhong region. This cult attracted both state endorsement and popular support. Thus, Guo Ziyi 郭子儀 (697–781), a famous military general in the Tang Dynasty, sought to renovate a temple and erect a monument for the River God. This monument was to serve as a cultural symbol that would strengthen the connection between the state and the local community, and hence ease the social tensions in the Hezhong area after the An Lushan Rebellion. In sum, such a construction would enhance the psychological and cultural identity of the people with both the mandate of heaven and the Tang imperial authority

Upper-Bound Limit Analysis of Ultimate Pullout Capacity of Expanded Anchor Cable

Expanded anchor cables have been widely used in the rapid development of underground engineering. However, there are still some deficiencies in the computation of the ultimate bearing capacity of expanded anchor cables. Based on the upper-bound theorem of limit analysis, the upper-bound solution of the ultimate bearing capacity of an expanded anchor cable was derived. For this calculation, the instability mechanism of the soil at the front surface of the anchorage segment of the expanded anchor cable was assumed to satisfy the logarithmic spiral failure model, its 3D velocity discontinuity surface was generated using the spatial discretization technique, and the optimal solution was determined through the particle swarm optimization (PSO) algorithm. The breakage mechanism of the anchorage side surface was assumed to appear at the interface between the anchorage body and the soil, and its velocity field satisfied the requirements of the associated flow rule. The accuracy of the proposed analytical solution was well-verified through a comparison with three-dimensional numerical simulations, and its superiority was also well-demonstrated in comparison to the existing theoretical calculation method. Subsequently, the influence of the key parameters of the anchor cable on the ultimate lateral resistance, end resistance, and total pullout capacity was discussed. The results showed that: the anchorage segment diameter, anchorage segment length, and buried depth of the expanded anchor cable had a great influence on the ultimate lateral resistance, ultimate end resistance, and total ultimate pullout capacity; however, the anchorage segment length had little influence on the ultimate end resistance, and the inclination angle of the anchor cable had relatively little influence on the resistance

Measuring the worldwide spread of COVID-19 using a comprehensive modeling method

Abstract Background With the global spread of COVID-19, detecting high-risk countries/regions timely and dynamically is essential; therefore, we sought to develop automatic, quantitative and scalable analysis methods to observe and estimate COVID-19 spread worldwide and further generate reliable and timely decision-making support for public health management using a comprehensive modeling method based on multiple mathematical models. Methods We collected global COVID-19 epidemic data reported from January 23 to September 30, 2020, to observe and estimate its possible spread trends. Countries were divided into three outbreak levels: high, middle, and low. Trends analysis was performed by calculating the growth rate, and then country grouping was implemented using group-based trajectory modeling on the three levels. Individual countries from each group were also chosen to further disclose the outbreak situations using two predicting models: the logistic growth model and the SEIR model. Results All 187 observed countries' trajectory subgroups were identified using two grouping strategies: with and without population consideration. By measuring epidemic trends and predicting the epidemic size and peak of individual countries, our study found that the logistic growth model generally estimated a smaller epidemic size than the SEIR model. According to SEIR modeling, confirmed cases in each country would take an average of 9–12 months to reach the outbreak peak from the day the first case occurred. Additionally, the average number of cases at the peak time will reach approximately 10–20% of the countries’ populations, and the countries with high trends and a high predicted size must pay special attention and implement public health interventions in a timely manner. Conclusions We demonstrated comprehensive observations and predictions of the COVID-19 outbreak in 187 countries using a comprehensive modeling method. The methods proposed in this study can measure COVID-19 development from multiple perspectives and are generalizable to other epidemic diseases. Furthermore, the methods also provide reliable and timely decision-making support for public health management
