ABSTRACT Introduction: Modern EEG technology can evaluate the current level of an individual's central functioning after analyzing the frequency of brain waves (II). The A wave (8 ~ 14Hz) of brain waves (EBG) is one of the most important index parameters in diagnosing the brain's central functioning level. Objective: To explore the effects of different training loads on the brain function of elite archers and provide an objective basis for improving the scientific level of archery training. Methods: The effects of EEG information and central nerve transmitters on athletes’ regulation and training were analyzed by testing and statistical methods. Results: Both HL-LLI and LL-HLI stages showed a decreasing trend in EEG complexity. Although the differences between the two stages were not significant all of them were considerably lower than the LL-LLI stage. The number of athletes with central fatigue in both stages showed an increasing trend. Conclusions: Athletes in training also need to focus on recovery after training, which requires a view of scientific training and scientific recovery as an organic whole that cannot be separated. Level of evidence II; Therapeutic studies - investigation of treatment results.

Most educational models that prescribe teaching and training methods to groom school children into innovators fail to take a deeper view of engineering design methodology. Yet others tend to ignore the importance of human values which must be an integral part of any innovative design process.  In this paper, We would first disaggregate design capabilities into its constituent capabilities, namely, exploring, creating and converging capabilities, which we need to master to produce better products and services, and then show how the cognitive and affective skills proposed by Benjamin Bloom, and Anderson and Krathwohl in their educational models can directly and significantly contribute to these constituent capabilities. With an improved understanding of the eco-system needed for better design solutions, we suggest that the present education systems, especially in developing countries, be critically reviewed and reoriented from the perspective of producing quality innovative designers, regardless of the problem area.

Some buildings hold certain qualities of space design similar to those originated from nature in harmony with its surroundings. These buildings, mostly associated with religious beliefs and practices, allow for human comfort and a unique state of mind. This paper aims to verify such effect on the human brain. It concentrates on measuring brain waves when the user is located in several spots (coordinates) in some of these buildings. Several experiments are conducted on selected case studies to identify whether certain buildings affect the brain wave frequencies of their users or not. These are measured in terms of Brain Wave Frequency Charts through EEG Device. The changes identified on the brain were then translated into a brain diagram that reflects the spiritual experience all through the trip inside the selected buildings. This could then be used in architecture to enhance such unique quality.

Fishery products are one of the products that have very limited durability and perishable so that the community, especially fishermen, preserve the product so that its freshness can last longer. One of the preservatives used is formalin, although it is very dangerous to human health. Some food products that contain formalin include: fresh fish, salted fish, tofu, wet noodles. Counseling on food safety needs to be continued widely to the public in various forms. This activity aims to educate and train partner groups on: 1) the dangers of formaldehyde on health; 2) characteristics of formalin food ingredients; 3) how to detect formalin foods; 4) eliminate / reduce formaldehyde levels in food products; 5) safe preservatives. The activities was carried out on February 7, 2019, in Desa Untia, Kecamatan Biringkanaya, Kota Makassar. The target group is fishermen and fisheries processors, as many as 23 people. The method used in service is counseling and training methods through lectures, discussions, and practice/training. The extension activity was attended by Untia village chiefs, local fisheries instructors, administrators of the All-Indonesian Fishermen Association (HNSI) and the target group. The activities went on smoothly and the target group enthusiastically attended counseling and training, because the knowledge/skills were needed to protect their families from the dangers of disease that could be caused by inappropriate use of formalin.

AbstractThe recently concluded 2019 World Swimming Championships was another major swimming competition that witnessed some great progresses achieved by human athletes in many events. However, some world records created 10 years ago back in the era of high-tech swimsuits remained untouched. With the advancements in technical skills and training methods in the past decade, the inability to break those world records is a strong indication that records with the swimsuit bonus cannot reflect the real progressions achieved by human athletes in history. Many swimming professionals and enthusiasts are eager to know a measure of the real world records had the high-tech swimsuits never been allowed. This paper attempts to restore the real world records in Men’s swimming without high-tech swimsuits by integrating various advanced methods in probabilistic modeling and optimization. Through the modeling and separation of swimsuit bias, natural improvement, and athletes’ intrinsic performance, the result of this paper provides the optimal estimates and the 95% confidence intervals for the real world records. The proposed methodology can also be applied to a variety of similar studies with multi-factor considerations.

Abstract Manipulation of plant growth via pruning and training methods has been carried out for as long as crops have been cultivated by man. These methods serve to not only improve the aesthetic value of ornamental plants, but also to increase yields, optimise fruit quality and prolong the productive life of horticultural crops. Pruning involves the selective removal of a diverse range of plant tissue. Branches, stems, roots, buds, flowers, leaves and young fruitlets may all be pruned depending on the purpose, species and growth form of the crop this is applied to. Training methods for horticultural applications are primarily used to support the plant and the weight of produce as it develops. Training structurally alters plant form, to alter the shape, size and direction of plant growth, it also allows optimal light interception and air flow and for ease of access for harvesting and other operations.

Abstract Background Blood draws are a routine element of the pediatric patient experience. They are also associated with the greatest fear and pain for a child. Because of the limited literature regarding phlebotomists' knowledge, experience, training, or stress related to their use of comfort techniques during pediatric blood draws, this study explored current practices and training methods. Phlebotomist training tends to focus on clinical technique rather than pediatric or patient comfort support. The study includes aims to develop a measurement for phlebotomists' use of comfort techniques for pediatric blood draws. Method Focus groups of parent advocates (n = 24) and pediatric phlebotomists (n = 11) reviewed the survey questionnaire, and it was revised before being e-mailed to hospital system phlebotomists (n = 128). Results Almost half of the sample group lacked training in child development. The most frequently used comfort measures were words of explanation and reassurance, positioning of the child, and distraction. Requesting child life specialist support and using pain management devices or topical anesthetics were used less often. Primary challenges to performing pediatric blood draws were anxious patients and parents. Conclusion Phlebotomists' use of available comfort measures occurs infrequently. Including child development and comfort techniques in training programs is essential to providing pediatric patients with a more satisfactory experience.

Learning by Choice of Internal Representations (CHIR) is a training algorithm presented by Grossman et al.1 based on modification of the Internal Representations (IR) along side of the direct weight matrix modification performed in conventional training methods. This algorithm was presented in several versions aimed to tackle the various training problems of nets with continuous and binary weights, multilayer and multi-output-neuron nets and training without storing the Internal Representations. The capability of one of these versions, the CHIR2 algorithm, to tackle multilayer training tasks of nets with continuous input vectors is examined in this paper. A comparison between the performance of this algorithm and of the Backpropagation algorithm2 is carried out via extensive computer simulations for the “two-spirals” problem, aimed to classify two classes of dots forming two intertwined spirals. The CHIR24 algorithm shows a rapid convergence rate for this problem, an order of magnitude faster than the results reported for the BP training algorithm (as well as those obtained by us) regarding the same training problem and network architecture.11 Moreover, the CHIR2 algorithm finds solution nets for the above mentioned problem with reduced architectures, reported as hard to solve by the BP training algorithm.11

In this paper, we present a handwritten character recognition (HCR) system that aims to recognize first-order logic handwritten formulas and create editable text files of the recognized formulas. Dense feedforward neural networks (NNs) are utilized, and their performance is examined under various training conditions and methods. More specifically, after three training algorithms (backpropagation, resilient propagation and stochastic gradient descent) had been tested, we created and trained an NN with the stochastic gradient descent algorithm, optimized by the Adam update rule, which was proved to be the best, using a trainset of 16,750 handwritten image samples of 28 × 28 each and a testset of 7947 samples. The final accuracy achieved is 90.13%. The general methodology followed consists of two stages: the image processing and the NN design and training. Finally, an application has been created that implements the methodology and automatically recognizes handwritten logic formulas. An interesting feature of the application is that it allows for creating new, user-oriented training sets and parameter settings, and thus new NN models.

This article provides a report on a finished piece of research. The study is divided into two stages. Firstly, the brain dominance and grammatical sensitivity of Pedagogy and Medical students in a Chilean university were measured. The correlation of both variables shows that Medical students are better at grammatical sensitivity than Pedagogy students and that left-brain dominance involves higher levels of grammatical sensitivity than right-brain dominance. The instruments used in this stage were: 1) a grammatical sensitivity pre-test (used to assess the students’ levels in this variable), 2) a brain dominance instrument (used to determine the cerebral preferences of the students) and 3) an abstract reasoning test (which measures a person’s ability to identify non numerical or verbal patterns). In the second stage, Pedagogy students underwent a five-session training aimed at improving their grammatical sensitivity. After the training was over, we administered a grammatical sensitivity post- test whose results were compared with the ones in the pre-test; the purpose was to determine if the training could improve the students’ performance in this variable. It was concluded that the training was successful since their grammatical sensitivity improved in 20%. In addition, most students with high attendance to the training (over 80%) improved their grammatical sensitivity after attending it.
