Class imbalance has become an ongoing problem in the field of Machine Learning and Classification. The group of data classes that are less known as the minority group, the other data class group is called the majority group (majority). In essence real data, data that is mined directly from the database is unbalanced. This condition makes it difficult for the classification method to perform generalization functions in the machine learning process. Almost all classification algorithms such as Naive Bayes, Decision Tree, K-Nearest Neighbor and others show very poor performance when working on data with highly unbalanced classes. The classification methods mentioned above are not equipped with the ability to deal with class imbalance problems. Many data processing methods are often used in cases of data imbalance, in this case research will be carried out using the Spider2 method. In this study, the Ecoli dataset was used, while for this study, 5 (five) different Ecoli datasets were used for each dataset for the level of data imbalance. After testing datasets with different levels of Inbalancing Ratio (IR), starting from the smallest 1.86 to 15.80, the results that explain that the KNN algorithm can improve its performance even better in terms of unbalanced data classification by adding the SPIDER- method 2 as a tool in dataset processing. In the 5 trials, the performance of the KNN algorithm can increase GM by 5.81% and FM 14.47% by adding the SPIDER-2 method to KNN.

Road safety monitoring systems are developing at this time. The transportation sector is the object of research that continues to be developed and is always an interesting topic. Not only for security purposes and for statistical purposes for the road widening process that supports road user infrastructure, but the detection system is also useful for sales marketing statistics. In this research, propose a vehicle detection system that is useful for widening roads in a certain area or area so that it can reduce traffic congestion and accident rates. The proposed Gaussian Mixture Model method has several weaknesses, such as errors in background substitution with vehicles and failing to distribute the background with vehicle shadows. However, using morphological operations can overcome these problems. The results show a fairly good level of accuracy from the proposed method. It is only less effective when using video objects with poor lighting or at night because in the blob analysis process the detected vehicle objects do not match the actual object. But if the traffic flow is smooth and unidirectional, the proposed method is still acceptable.

Copyright is a serious problem in the digital world, the process of sending and distributing digital media is so easy nowadays, copyright in the digital world is very detrimental to those who feel that their digital rights are copied and pasted or taken without the consent of the creator. Therefore we need a way where when a digital file can be identified as original as a product, one of the right ways is to use a watermark technique. But often this watermark process can be lost or cannot be extracted because the digital file has gone through a compression process, duplicate, or something else. So in this study, it will be tried to increase the durability of a watermark in digital audio as a solution for identifying copyrighted digital works. Where the watermark process will use the RSA and MSB algorithms to enter information into a digital audio file, later this information can be extracted to view copyright ownership information from the digital audio. And it is hoped that this watermarking is resistant to various digital audio processes such as compression, duplication, and editing carried out on the file. the information that is inserted into is maintained without compromising the quality of the digital audio.

Published: August 2021

Angular and rotational limb deformities are common orthopedic disorders in dogs. These deformities are more commonly seen in the radius and ulna of dogs. The leading cause is local trauma to the distal growth plates of these bones, resulting in interruption of ulnar growth with continued radius growth. Corrective osteotomies with adequate bone fixation are relatively complex but highly successful techniques in the treatment of angular and rotational deviations. This review highlights the importance of surgical planning using the angular rotation center (Cora) methodology in the treatment of angular deformities. Main techniques of corrective osteotomies are reviewed.

Published: August 2021

The contents of the Senate Bill 956, better known as the Teachers' Protection Policy Act was examined and analyzed based on the following themes, namely, support mechanisms for public school teachers and personnel, enhanced protection of public-school teachers and personnel, and training on guidelines and classroom discipline for public school teachers and personnel. According to the Republic Act, 4670 or the Magna Carta for Public School Teachers, the appropriateness of the act was checked to see how much help this bill can provide to the public-school teachers in the Philippines in terms of classroom discipline and classroom management. The bill poses excellent benefits to the public-school teachers. However, the Department of Education must identify which disciplinary acts or strategies are not categorized as child abuse and that there should be centralized policy implementations, seminars, and training to avoid misinterpretations and discipline avoidance among teachers. This paper hopes to contribute to a research-based, logical, and relevant drafting of HR policies and programs to support and protect the teachers as mandated in the Magna Carta for Public School teachers and SB 956. This study employed a qualitative method using resources available online.

Emergency Remote Early Childhood Teaching: A Temporary Setting or Contemporary Necessity?
Authors: Mahinay Jasmine , Merin Jewish
Published: August 2021

The COVID-19 pandemic and the protection of social distance between educators and learners have impacted all levels of education – significantly, early childhood. It has hindered activities carried out in a direct meeting and has forced education in the 2020-2021 school year to continue through emergency remote teaching. The study determined the fundamental structure of the views of early childhood educators on emergency remote teaching to reveal how they are thinking forward regarding their teaching skillset for either the continuity or change of education in the next school year. A phenomenological design of qualitative research was employed, and a local sample of 10 educators voluntarily informed the study. Through the interviews, five theme clusters emerged that reflected their 88 significant statements. The results evidenced to the extent that early childhood educators view emergency remote teaching as beyond being a temporary solution to learning when a pandemic threatens physical classes, but its potential to become a contemporary necessity is premature and highly dependent on how families will respond and how schools will proceed as a result of their response. Thus, further exploration of professional development topics is needed to support early childhood educators to teach in any situation moving forward.

Biofuels are a sustainable energy option that can contribute to solve some current environmental problems. For example, it seems imperative to find alternative energy sources; and among them adequate and sustainable raw materials to produce biofuels, such as bioethanol. This study, under the assumption that Maralfalfa grass would be a suitable substrate to produce biofuel, aimed at evaluating the biomass yield, chemical composition, and theoretical bioethanol production of Maralfalfa grass (C. purpureus Schumach.) Morrone harvested at three cutting frequencies (CF). Treatments were distributed in a randomized complete blocks design with split-plots arrangement and three replicates. Analysis of variance was done with GLM procedure and means were compared with Tukey test (p≤0.05). At 120 d, the lignocellulosic material content was the highest (p≤0.05) with 66% of holocellulose, 30% hemicellulose, 22% lignin, 1.8% acid soluble lignin, 20% acid insoluble lignin, 26% acid insoluble residue, and 6.2% ashes. The highest concentration of extractives compounds was found at 150 d harvest frequency (15.5%; p≤0.05), while the highest biomass production (32.6 Mg ha-1 y-1), calorific value (21.0 MJ kg-1), and bioethanol production (239.9 L Mg-1 MS-1) was obtained at the 180 d (p≤0.05). No significant changes were found for crude protein (p>0.05). Results showed that Maralfalfa grass (C. purpureus Schumach.) Morrone is an attractive alternative for bioethanol production due to high biomass yield and chemical composition at short harvesting times.

Introducción: Los ríos andinos en Colombia están fuertemente influenciados por diferentes actividades antrópicas. Los macroinvertebrados han sido utilizados para evaluar la calidad del agua en estos ecosistemas. Objetivo: Este estudio analizó el comportamiento de diferentes índices basados en macroinvertebrados para evaluar la calidad del agua del tramo medio-bajo del río Jordán en Jamundí (Colombia). Materiales y métodos: Se ubicaron tres estaciones de muestreo: E1 (1173 m.s.n.m.), E2 (1069 m.s.n.m.) y E3 (1019 m.s.n.m.). Se colectaron individuos en grava, bolos y macrófitas (n=15) y se midieron las concentraciones de variables fisicoquímicas y microbiológicas (n=15). Se evaluaron los índices de calidad de agua ICA-NSF y bióticos (BMWP/Univalle, ASPT y EPT) y los índices de Shannon-Weaver, Margalef y Simpson. Se realizó una correlación de Spearman entre las matrices de similitud biótica y ambiental. Resultados: El ICA-NSF presentó variaciones espacio temporales no significativas entre las estaciones de muestreo, con calidades de agua entre “regular” y “excelente”. Los índices de diversidad mostraron que la equidad y riqueza son mayores en la estación E1. El BMWP/Univalle evidenció la influencia de las diferentes actividades sobre la subcuenca del río Jordán, clasificando la estación E1 como “Buena”, E2 “Aceptable” y E3 “Dudosa”. Las variables que mejor explicaron el patrón de diversidad fueron las asociadas a la contaminación orgánica (DBO5 y Coliformes totales). Conclusiones: Integralmente, los índices muestran que la mejor calidad del agua se presenta en la estación E1 donde la influencia de las actividades antrópicas es menor.

O estudo aborda o tema “Utilização de plantas de cobertura como alternativa de manejo sustentável”. Trata-se de uma pesquisa bibliográfica, pautada nos pressupostos teóricos de vários autores e fontes sobre o tema abordado no presente estudo. Nestes termos, o estudo teve como principal objetivo apresentar informações relacionadas a utilização de plantas de cobertura como alternativa de manejo sustentável, com a finalidade de gerar informações que auxiliem pesquisas futuras, bem como para nortear produtores quanto a implementação dessa prática visando a conservação ambiental. O estudo se justifica devido ao aumento da população mundial demandar uma grande quantidade de alimentos produzidos, o que se torna um desafio, produzir em quantidade e com qualidade considerando a sustentabilidade. Diante dessa problemática, as plantas de cobertura quando adequadamente utilizadas constituem uma estratégia para melhoria dos atributos físicos, químicos e biológicos do solo agregando incremento na produtividade e sustentabilidade ao sistema agrícola. Como resultado percebe-se que a utilização de plantas de cobertura é uma alternativa promissora para implementar a produção sustentável almejada pela agricultura moderna.

A COMPARATIVE ANALYSIS ON THE RELATIONSHIP BETWEEN ORGANIZATIONAL CULTURE AND SERVICE QUALITY IN PUBLIC AND PRIVATE UNIVERSITIES IN KENYA
Authors: Ngugi Diana Wanjiku , Gachunga Hazel , Mukanzi Clive
Published: August 2021

Purpose: The purpose of this study was to compare the relationship between Organizational Culture and Service Quality between public and private universities in Kenya.

Methodology: The methodology of this study comprised of descriptive and causal research designs. The target population was 2,475 teaching staff in the 23 chartered public and 17 chartered private universities in Kenya. Sample size comprised of 225 teaching staff in the business program in two chartered public and two chartered private universities in Kenya. The collected questionnaires were 189 (Public 75, Private 114) which resulted in a response rate of 84%.

Findings: The study findings showed that, in universities in Kenya, there was a significant difference in means of Organizational Culture between public (mean=3.60, p-value=0.000<0.05) and private (mean=4.13, p-value=0.000<0.05), with private universities having a higher mean. The study findings showed that, in universities in Kenya, there was a significant difference in means of Service Quality between public (mean=3.68, p-value=0.000<0.05) and private (mean=4.18, p-value=0.000<0.05), with private universities having a higher mean. The findings also showed that Organizational Culture has a positive, significant relationship with Service Quality in both public (r=0.649, p-value=0.000<0.05) and private (r=0.587, p-value=0.000<0.05) universities, where the relationship was stronger in public universities compared to private universities. Organizational Culture has a significant influence on Service Quality in Public universities (r2=0.421) and in Private universities (r2=0.345). The study concluded that there is indeed a significant, positive relationship between Organizational Culture and Service Quality in both public and private universities in Kenya. The Study also concluded that Organizational Culture was a significant predictor of Service Quality in both public and private universities in Kenya.

Unique contribution to theory, practice and policy: This study made an outstanding contribution to theory by validating use of systems theory of management. The study also contributed greatly to theory by showing a significant relationship between Organizational Culture (using DOCS) and Service Quality (using SERVQUAL) as measurement instruments in public and private universities in Kenya. This study recommended that leadership in public universities needs to emulate the culture in private universities so that there is higher service Quality for the students. Also, leadership in private universities need to improve on how they use their strong and positive organizational culture to deliver Service quality to its students amidst the unique challenges they face.
Non-negative Solutions of the Nonlinear Diophantine Equation (8^n)^x + p^y=z^2 for Some Prime Number p
Authors: SINGHA Boorapa
Published: August 2021

In this paper, we explain all non-negative integer solutions for the nonlinear Diophantine equation of type 8x + py = z2 when p is an arbitrary odd prime number and incongruent with 1 modulo 8. Then, we apply the result to describe all non-negative integer solutions for the equation (8n)x + py = z2 when n ≥ 2. The results presented in this paper generalize and extend many results announced by other authors.
HIGHLIGHTS

Studying a new series of the equation 8x + py = z2 when p is prime which is not congruent to 1 modulo 8
Describing all non-negative integer solutions of the equation (8n)x + py = z2 which is a generalization of the equation 8x + py = z2
The equation 8x + py = z2 has at most 3 non-negative integer solutions when p is congruent to 1 modulo 8 and p ≠ 17
