Published: May 2023

Abstract—Indonesia still has a high prevalence of diarrhea cases, which is 14.5% in 2020. Diarrhea can cause malnutrition, dehydration, kidney damage, and a weak immune system, so an effective solution is needed to reduce the number of diarrhea cases. Mangroves are known to contain various secondary metabolites that play a role in the health sector, such as antimicrobials, antivirals, and antifungals. This review article aims to review whether the antibacterial activity of mangroves can suppress the growth of bacteria that cause diarrhea, namely Staphylococcus sp. and Shigella sp. Based on a review of six selected research articles, it is known that various mangrove species have antibacterial activity against Staphylococcus sp. and Shigella sp. The strength of these activities against the two bacteria is determined by several factors, including the extraction method used and the chosen solvent. With these results, it is hoped that mangroves can become an affordable alternative medicine for various groups of people to cure diarrhea, thus the number of diarrhea cases in Indonesia can decrease.

Abstract
Heat stress (HS) is considered a severe concern for rabbit buck’s health, welfare and reproductive features. Thymoquinone (THQ) is a natural molecule with robust antioxidant, antimicrobial, and anti-inflammatory properties. Thereafter, three months of feeding research was applied to assess the role of THQ-enriched diets in improving the health, semen attributes and testicular changes of stressed rabbit bucks. Forty rabbit bucks were used in this research, and animals were fed diets containing 0 (THQ0; serve as a heat stress group), 100 (THQ100), 200 (THQ200), and 400 (THQ400) mg/kg of THQ for three months continually during the summer season. Outcomes displayed that THQ significantly enhanced FBW (final body weight), DBWG (daily body weight gain), and FI (feed intake) but did not affect FCR (feed conversion ratio). Compared with the THQ0 group, dietary THQ addition significantly decreased creatinine, TB (total bilirubin), TG (triglycerides), and GGT (gamma-glutamyl transferase) levels. Bucks receiving 200 mg of THQ had higher TAC (total antioxidant capacity) and GSH (glutathione) than other groups. At the same time, MDA was significantly shrunk in THQ-treated groups relative to the THQ group. The levels of interferon-gamma (IFN-γ) and interleukin-4 (IL-4) were significantly diminished (P <0.001), but nitric oxide and lysosome activity were significantly increased in bucks given diets containing THQ (200 and 400 mg/kg) as relative to the TH0 group. Libido score and reaction time were significantly improved by THQ dietary inclusion. Semen attributes, including volume, motility, concentration, and vitality, were significantly augmented in THQ100 and THQ200 groups. Histological screening of testicular tissues showed moderate to severe degenerative and necrotic changes in the testicular tissues of bucks exposed to HS. This was enhanced with the supplementation of THQ at different levels. Collectively, THQ (200 or 400 mg/kg diet) can improve health, semen attributes and restore testicular damage in rabbit bucks via boosting antioxidant and reducing inflammatory cytokines.

Abstract

In-vitro meat production has entered into the phase of pilot-commercial scale production from the conceptual-laboratory phase. The main challenge for in-vitro meat production on a commercial scale is the very high cost of its production, mainly due to the cost of cell culture media, growth regulators, and the requirement of highly skilled manpower. The development of serum-free and animal-free culture media with plant, microbial, and fungi-derived compounds through recombinant technology and media recycling is crucial for scaling up in-vitro meat production and reducing the price of the end products. The proper design of bioreactors specific to in-vitro meat production, their automation, utilization of natural and edible scaffolds, and microcarriers made up of edible materials are the present focus of researchers. The co-culturing by proliferating various cells such as adipocytes, chondrocytes, fibroblasts, and endothelial cells are applied for imparting textural and organoleptic attributes to developed products similar to conventional meat. The industrial process to produce in-vitro meat needs a clear synergy between the biological, chemical, technical, and industrial fields because at the moment the main research focus is on the development and improvement of cell lines available to set up cell culture and culture media, bioreactors, cell lines, scaffolding, and biofabrication. The research on in-vitro meat is limited by the fact that from the industry the protocols are not properly divulgated.

Abstract
In the 3d dense map construction system of indoor scene by mobile robot, the existing single sensor method cannot improve the positioning accuracy and reconstruction accuracy of robot, as well as the requirement of rapidity. Therefore, it is applied to THE ORB-SLAM with three parallel threads of track tracking, map reconstruction and loopback detection. Through depth camera pose to splice point cloud of building three-dimensional dense point cloud, in the 3 d reconstruction, a computer can not rely on GPU parallel computing, using only the CPU recovery environment three-dimensional dense scene map method, further reduce the time of the map construction, improve the efficiency of the reconstruction, thus improve the overall performance. Since only the ORB features were retained in the map during the construction of ORB-SLAM2, sparse point cloud map was established. Fortunately, the framework structure of ORB-SlAM2 was relatively clear. Only one thread needed to be added for the maintenance of point cloud map, and the key frames generated by ORB-SLAM2 were passed into the point cloud map construction thread. Use incoming keyframes to generate a map with dense point clouds.

Published: May 2023

Abstract
With the rapid development of information technology, the informatization, integration and complexity of more and more large equipment are increasing day by day, so it is very important to carry out fault diagnosis for such complex equipment. In the traditional way, expert system technology is usually used for fault diagnosis of complex equipment. However, with the increasing of equipment data information, traditional methods cannot solve the fault diagnosis requirements in the case of a large amount of data. Therefore, data-driven fault diagnosis method can solve this problem, The carrier of data-driven fault diagnosis is a large amount of engineering data, and its focus is to explore new methods of fault diagnosis from a large amount of historical data. In this paper, the classical random forest algorithm is selected as the basic model, and aiming at the imbalance of complex equipment data, the improved random forest voting mechanism based on the fault ratio is proposed to optimize the model, which makes the final model diagnosis accuracy more than 95%, and has good application value.

Abstract
Using each part of the image's spatial information to generate better local details of the image is a key problem that super-resolution reconstruction has been facing. At present, mainstream super-resolution reconstruction networks are all built based on convolutional neural networks (CNN). Some of these methods based on Generative Adversarial Networks (GAN) have good performance in high-frequency details and visual effects. However, because CNN lacks the necessary attention to local spatial information, the reconstruction method is prone to problems such as excessive image brightness and unnatural pixel regions in the image. Therefore, using the capsule network's excellent perception of hierarchical spatial information and local feature relationships, the author proposes a super-resolution reconstruction based on capsule network CSRGAN. The experiment's final result shows that compared with the pure convolution method RDN, the PSNR value of CSRGAN is increased by 0.14, which is closer to the original image.

Authors: Hoang Xuan Thinh 
Published: May 2023

Abstract
A study about multi-objective optimization of turning process has been done in this paper. Twenty-five experiments of a matrix designed according to Taguchi method have been performed. In each experiment, the values of five parameters were changed, including tool nose radius, tool holder length, spindle speed, feed rate, and cutting depth. The three output parameters determined for each experiment include surface roughness, roundness deviation and material removal capacity. Four different methods were used to calculate the weights of the output parameters. The FUCA method was used to solve the multi-objective optimization problem. This work was repeated four times with four corresponding weight sets of the criteria. The purpose of solving the multi-objective optimization problem is determining the values of the input parameters to ensure both the surface roughness parameter and the roundness deviation parameter are the smaller the better, and the material removal capacity is the larger the better. A surprising thing happened, the optimal values of the set of input parameters were exactly the same when using four different weighting methods. Accordingly, the optimal values of tool nose radius, tool holder length, spindle speed, feed rate and cutting depth correspondingly are 0.8 (mm), 40 (mm), 587 (rev/min), 0.316 (mm/rev) and 0.6 (mm).

Productive reading is the key component of the productive linguodidactic technology system. One of the important professional competences that college undergraduates are supposed to acquire is a skill to reflect critically on what they read. They have to learn how to analyze and interpret large flows of information from various sources including those from the foreign media. The important skill of interpretating the value and the meaning of the text in terms of ideas and author’s intentions can be built through productive linguistic reading. The effective application of the text structure strategy can be seen as one of the ways to implement a productive reading approach.This article focuses on the ways used to engage students in higher order thinking activities while reading articles and other authentic texts on various topics. Identifying the main ideas and logical relationships between them, providing background information, and generating inferences enhance undergraduates’ skills to form and articulate an informed and well-grounded opinion on different issues.

Introduction: Stress is the body's response to threatening external stimuli. Many medical students experience stress. Stress that medical students share can be caused by learning demands, interpersonal problems, and other things. Even though stress is daily, excessive stress can also cause various health problems, including headaches. Headache is the most common neurological problem in the world. There are several types of headaches, one of which is tension headaches. However, the relationship between stress and headaches, especially tension-type headaches in medical students, has yet to be widely studied.
Methods: This study is a cross-sectional analytic observational study, on 120 pre-clinical students (22 males, 98 females) aged 18-21 from the School of Medicine and Health Sciences, Atma Jaya Catholic University in Jakarta. The questionnaire used to measure the respondent's stress levels were the Depression Anxiety Stress Scale 42 (DASS-42) and Headache Screening Questionnaire (HSQ) to determine the respondent's headache. The data obtained were analyzed statistically using the Chi-square method, with a p-value <0.05.
Results: Out of 120 students, 74.2% experienced stress within normal limits, while 9.2%, 10%, 5%, and 1.7% reported experiencing mild, moderate, severe, and very severe stress levels, respectively. 30.8% of students experienced tension-type headaches, and 69.2% of students did not. The result obtained from the chi-square bivariate test was p = 0.188.
Conclusions: There is no association between stress and tension-type headaches in medical students of the School of Medicine & Health Science, Atma Jaya University.
