Published: March 2020

Abstract
In this paper, we propose and investigate a stochastic SIRI epidemic model with saturated treatment and incidence rates. Firstly, by constructing a suitable Lyapunov function, we establish the existence and uniqueness condition of the global positive solution of the model. After that, we obtain the thresholds of the random SIRI epidemic model. Then, we consider the asymptotic behavior of the stochastic SIRI model. Lastly, numerical simulations are introduced to illustrate our results.

Abstract
Flowers are a common species in people’s lives, but people’s understanding of flowers is not comprehensive. The traditional UI display method lacks immersion and interactivity. This paper proposes a method based on the deep learning neural network flower recognition algorithm to recognize the flower target information and replace the traditional UI with the AR information to display the flower information. The tracking and positioning technology used in the floral AR display method is a very important underlying technology. This paper focuses on the tracking technology of flower target, and proposes a server-based flower recognition neural network algorithm recognition algorithm. After identifying the flower information and detection frame, it outputs the detection frame parameters of the flower target, and then combines the OpenCV KCF tracker pair. The method of performing AR display of the flower information has high tracking accuracy and stability.
Study on Medication Regularity of Sijunzi Decoction and Its Categorized Prescriptions Based on Attribute Partial Order Structure Diagram
Authors: Song Jialin , Han Xiaoying , Meng Hui 
Published: March 2020

Abstract
Sijunzi decoction is a famous prescription in traditional Chinese medicine (TCM) for the treatment of spleen deficiency syndrome. Spleen deficiency syndrome is manifested in a variety of symptoms. Herbs can be added or replaced on the basis of Sijunzi decoction according to different symptoms, forming Sijunzi categorized prescriptions. In this paper, the medication regularity of Sijunzi decoction and its categorized prescriptions was studied based on attribute partial order structure diagram (APOSD). According to prescription-herb APOSD generated from Sijunzi decoction categorized prescriptions screened from comprehensive TCM database, it can be seen that three herbs are used in all prescriptions, i.e. Renshen, Baizhu and Fuling. Different forms of Sijunzi decoction mainly depend on whether the forth herb is Zhigancao, Chenpi-Gancao, or Gancao. The efficacy of common herbs in the prescriptions for different symptoms can be presented by prescription-herb APOSD and prescription-symptom APOSD generated from different prescription subgroups. The experimental results show that APOSD can effectively reveal the medication regularity of Sijunzi decoction and its categorized prescriptions, and it is an useful tool for theoretical study of TCM.

Abstract
Most textbooks that are provided by the government employ a lot of non-routine problems in their exercise practice. However, students are incapable of understanding the non-routine problems and they struggle in using their reasoning power which affects the overall achievement of mathematics. The purpose of this study is to identify the students’ ability in relation to adaptive reasoning and strategic competence through Problem Based Learning (PBL) model. This study involved six seventh graders in middle school. Data on students’ adaptive reasoning capabilities and strategic competencies are collected through tests which were conducted over five learning sessions with the PBL model. The research data was analyzed descriptively by comparing test result and interview with the indicator of adaptive reasoning and strategic competences ability. The results show that students’ adaptive reasoning ability can be initiated through learning by PBL model. Two out of the three strategic competence indicators are met by all students. The two indicators are understanding and presenting math problems to verbal forms and selecting the right formula, approach and/or method to solve the problem. Only one indicator of strategic competence is not achieved, which is checking the truth on the settlement of problems that have been obtained. This study provides an overview of the importance of training students to answer non-routine problems through learning. It is a challenge for teachers to familiarize students with systematic steps through various strategies that involve reasoning.

Abstract
Schools in Banda Aceh city are often traversed by traffic passing vehicles that exhaust emissions such as Pb, CO, NOx, SOx and CO2. The presence of open green space (OGS) is beneficial in cleaning air pollution. Thus, it is necessary to identify the tree architecture model to ensure suitable types of plants in the school’s green space area. This study used an exploratory survey method. To measure the OGS ratio, the GPS was used to collect the data to get the proportion of the school area with canopy and then the result was converted to a percentage. The architectural model was identified according to the guidelines from Halle and Oldeman. The results showed that 12 schools in Banda Aceh city meet ideal requirements for the proportion of OGS according to Law No. 26 of 2007, and only one school (SHS 13) does not satisfy the requirements. The highest OGS was identified at SHS 16 (79%); while the lowest is at SHS 13 (28%). The tree architectural models found in this study are Scarrone, Corner, Attims, Troll, Roux, Leeuwenberg, Koriba, Rauh, Aubreville and Stone. The dominating tree architecture model of those schools is the Troll model (35.7%) with 15 species.
