Proportional-integral-derivative (PID) control algorithm with its various forms, namely P (proportional), PI (proportional-integral), PD (proportional-derivative), PID, and compensators, is considered the most applied and widely used control algorithms in industry; this is because of its simple construction, robustness and capabilities to achieve desired control over plant performance. Designing PID algorithm is accomplished with a compromise to result in an overall system responds with acceptable levels of stability, response fastness, smoothness and costs. Various PID design methodologies and expressions have been introduced in text and literature,each has its advantages, disadvantages and limitations. In the present work, a new, efficient, simple, easy to apply and linear expressions for PID algorithmP-. PI, PD, and PID modes design are derived and presented. Expressions are derived based on relating parameters of both controller and plant. The expressions are intended to control the behavior of second order systems and approximated as such systems, such that it responds with acceptable stability level, minimum possible overshoot, oscillations and steady state error. To further improve the resulted response, only one tuning parameter α, is introduced To test, analyze, and evaluate the design expressions, MATLAB/Simulink software was used. A simulation model was built by integrating the next sub-models; PID control algorithm modes, drive with limitation and saturation blocks, sensor, desired output signal generator and finally various forms of second order systems. The simulation model was developed and refined to be as close as possible to real life conditions and processing. Studying the recorded testing, graphical and numerical results show that the suggested expressions are being simple and easy to apply, and also efficient in providing better control over controlled system’s behavior in terms of response measures and performance indices.Moreover, expressions are efficient to speed up response and eliminate or reduce overshoot, rise time and settling time. Studying results show that, the overall system responds with acceptable fast response, in most cases without overshoot, oscillation and with minimum steady state error and better ISE and IAE indices values.

The purpose of the study is to determine the students` attitudes, assess their learning environment, and find out the relationship between students` attitudes and learning environment in virtual laboratory class among 173 science education students from the College of Education, Central Mindanao University. This quantitative study used descriptive correlation research as research design and data analysis. The results of the study revealed that the students' attitude in virtual laboratory classes in terms of inquiry was acceptable, and the enjoyment was highly acceptable among the respondents. For the learning environment in virtual laboratory classes, five dimensions were moderately practiced, namely: integration, material environment, teacher support, task orientation, and investigation. Only the dimension of differentiation was fairly practiced among the science education students. The result of the Pearson (r) correlation shows the significant relationship between the learning environment and students' attitudes in virtual laboratory classes. The study recommends that enhancing the setup for virtual laboratory is one of the keys to promoting a positive attitude and in performance of the students in the activities and experimentations.

This study investigated the factors that influence the business performance of micro-enterprises in Northern Mindanao. Specifically, it examined the profile, marketing practices, entrepreneurial orientation, access to finance, and business performance of these enterprises. The study used responses from 417 micro-enterprises selected through stratified random sampling from the provinces of Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental and Misamis Oriental. A descriptivecorrelational research design was employed to attain the objectives of the study. More than half of micro-enterprises employed 1-4 employees and undertook their business for not more than five years. Marketing practices are implemented most of the time. Their entrepreneurial orientation was high, access to finance was moderate to great, and their business performance for the last three years was average to good. The aggregate multinomial logistic regression analysis reveals that among the variables used in the study, business age, marketing practices, entrepreneurial orientation, and access to finance significantly influence the business performance of micro-enterprises. The multinomial logistic regression per industry analysis yields a different result. In merchandising industry sector, marketing practices, business age, and access to finance influence substantially business performance. In the service industry sector, entrepreneurial orientation, business age, and access to finance significantly influence business performance.

Background: Obesity, overweight and elevated BMI are clinical features of PCOS, and between 40-80% of women with PCOS are reported to be overweight or obese. This study aimed to categorize values of patient anthropometric variables such as BMI with change in follicular sizes as determined by sonography following postCLOMID inducement therapy. Materials and Methods: This was an experimental cohort study carried out in some selected hospitals in Anambra State, Nigeria, from June 2018 to May 2022.Convenient sampling technique was adopted to select the subjects based on the inclusion criteria, which were women of child bearing age (18 to 45 years) for both groups. Confirmation of patients with PCOS was ascertained with the presence of polycystic ovaries in ultrasound. The ultrasound examinations and anthropometry measurements were carried out on each subject, and data such as BMI, follicular sizes before and post treatment were recorded. The obtained data were subjected to SPSS analysis using both descriptive and inferential statistical tools. Results: The mean values of the BMI of the participants in the experimental group before and after treatment with clomid were 25.69±5.99 kg/m2 , 25.92±5.55 kg/m2 respectively, while the mean BMI value for the control group was 23.09±3.41 kg/m2 .There were no statistically significant differences in body mass index, and maximal follicular size in women with failed and successful ovulation in the experimental group before treatment (p>0.05). There were statistically significant mean differences in the BMI (t= 8.75, p = 0.001) and follicular size (t= 2.04, p = 0.04) of participants in the experimental group after treatment with clomid. There were statistically significant mean differences in the BMI (t= 2.41, p = 0.02) and follicular size (t= 4.88, p = 0.001) of participants in the control group after treatment with clomid. Conclusion: There was higher ovulation failure rate among the overweight and obese subjects in both the experimental and control groups. Also significant increase in mean follicular sizes after clomid inducement in the experimental group was noted. Body mass index has significant negative impacts on ovulation.
背景:肥胖、超重和BMI升高是多囊卵巢综合征的临床特征，据报道，40-80%的多囊卵巢综合征女性超重或肥胖。本研究旨在对clomid诱导治疗后超声检查确定的患者人体测量变量(如BMI)与卵泡大小变化的值进行分类。材料和方法:这是一项实验性队列研究，于2018年6月至2022年5月在尼日利亚阿南布拉州的一些选定医院进行。采用方便抽样方法，根据纳入标准选择研究对象，两组均为育龄妇女(18 ~ 45岁)。超声检查显示多囊卵巢，可确诊多囊卵巢综合征。对每位受试者进行超声检查和人体测量，记录治疗前后BMI、卵泡大小等数据。使用描述性和推理性统计工具对获得的数据进行SPSS分析。结果:实验组受试者在克罗米芬治疗前后BMI均值分别为25.69±5.99 kg/m2、25.92±5.55 kg/m2，对照组BMI均值为23.09±3.41 kg/m2，治疗前实验组排卵失败和排卵成功女性的体重指数、最大卵泡大小差异无统计学意义(p>0.05)。实验组受试者经克罗米芬治疗后BMI (t= 8.75, p = 0.001)和卵泡大小(t= 2.04, p = 0.04)的平均差异有统计学意义。对照组治疗后BMI (t= 2.41, p = 0.02)和卵泡大小(t= 4.88, p = 0.001)的平均差异有统计学意义。结论:超重和肥胖受试者的排卵失败率高于对照组。实验组经克罗米芬诱导后，平均卵泡大小显著增加。体重指数对排卵有显著的负面影响。

The study aims to assess the students’ level of knowledge, attitudes, beliefs, and academic performance in a dynamic learning program (DLP). The Dynamic Learning Program (DLP), which is based on activity-based multidomain learning, requires students to work independently in order to read the concept notes and complete the exercises before the lesson is discussed and explained. This way, students can independently discover and understand the lesson. Students learn more by acting than by merely listening, according to the theory. This study utilized descriptive statistics to determine the students’ level of knowledge, attitudes, beliefs, and academic performance. The Pearson Product Moment Correlation Coefficient and multiple-linear regression were both used to determine which variable or variables, alone or in combination, best predict students' academic achievement in mathematics. This study was conducted at Pangantucan Community High School, Pangantucan, and Bukidnon. The respondents of this study were the 120 grade-11 students who were exposed to Dynamic Learning Program. The results of this study shown that the students are highly knowledgeable about DLP, and this teaching methodology was highly accepted and valued by the PCHS students. The academic performance of the students is above the average, it implies that the students who were exposed to dynamic learning programs have a good performance in their mathematics subject. However, the Pearson product-moment correlation showed that the student’s knowledge, attitude, and beliefs on Dynamic learning Program was not significantly correlated to their academic performance. And also, in the multiple-linear regression results showed that students’ knowledge, attitudes, and beliefs on dynamic learning couldn’t predict the academic performance of the students in their mathematics subject during modular distance learning modality.

The City of Ekurhuleni is a major metropolitan municipality that provides essential municipal services 3, 178, 470 residents and ratepayers. The purpose of research was to determine the level of satisfaction of people who live and work in the City of Ekurhuleni with the quality of municipal services they are provided with routinely. The survey was conducted by gathering household-level information from 544 residents of Ekurhuleni. The level of satisfaction of respondents with the quality of municipal services was measured by using a matrix of indicators developed by Das, Das and Barman (2021:885-913) for conducting a similar assessment. A composite index developed by D’Inverno and De Witte (2020:1129-1141) was used as a benchmark for measuring the level of services rendered to people who live in the City. The main result of the survey was that 63.05% of people who took part in the survey expressed satisfaction with the quality of services that were rendered to people living in the City. The results showed that 36.95% of people in the survey were not happy with the quality of services rendered to people who live in the City. The survey revealed that satisfaction with services was influenced by the ability of employees of the City to resolve service-related queries promptly, a lengthy duration of residence in Ekurhuleni (11 years or longer), and being provided with accurate financial statements.

Orthodontic tooth movement animal models are important carriers for studying orthodontic tooth movement. Experimental animals that can be modeled include: rats, mice, dogs, rabbits, etc. How to select suitable animal models for different scientific problems is very important. Therefore, this paper reviews the types and characteristics of orthodontic tooth movement animal models, and focuses on the similarities and differences of rodent anatomy, modeling methods and considerations. It is found that there is a lack of unified modeling standards for orthodontic tooth movement animal models. Thus appropriate animal models should be selected according to actual needs.

Food is the main fuel that runs a human body, both in health and illness. Food and Nutrition play a major role in the prevention of almost all diseases and promotion of health. Unfortunately at the global level, India is being placed among the highest ranked countries on the basis of number of malnourished children1. Childhood is a crucial period where we need to pay some extra attention for the nutritional needs and nutritional care of a child, as it acts as a strong pillar for his/her growth and development and prevention of malnutrition. Despite many medical advances over the past 20 years, the prevalence of malnutrition among hospitalized children has not decreased. Since the staff nurses spent more time with patients than any other healthcare workers and the patient recovery is greatly affected by the quality of care these nurses provide to their patients in all the aspects of care, including the nutritional aspect. Present study was conducted to assess the Nurses’ Knowledge, Attitude and Practice towards nutritional care of the hospitalized children, in order to ensure quality nutritional care for hospitalized children who are at risk of developing malnutrition or who are already victims of it. A nonexperimental descriptive research design was adopted to carry out the present study on a sample of 40 staff nurses working at a Tertiary care hospital of Karnataka by administering MKAP questionnaire. The results of the study showed that majority of the staff nurses 28(70%) had average knowledge and neutral attitude regarding malnutrition and nutritional care among hospitalized children , while as 7(17.5%) had good knowledge and positive attitude and 5( 12.5%) of them had poor knowledge and negative attitude regarding malnutrition and nutritional care among hospitalized children. The majority of the staff nurses 25(62.5%) showed neutral practice regarding malnutrition and nutritional care among hospitalized children, while as 10 (25%) showed beneficial practice and 5 (12.5%) of them showed non-beneficial practice regarding malnutrition and nutritional care among hospitalized children. In the present study the association of Levels of KAP with demographic characteristics of the staff nurses was calculated by using chi-square test and no association was found between the two except for gender. The study concluded that most of the staff nurses are having average knowledge and neutral attitude and practice towards malnutrition and nutritional care of hospitalized children

Food and Nutrition play a major role in the prevention of almost all diseases and promotion of health. Unfortunately at the global level, India is being placed among the highest ranked countries on the basis of number of malnourished children1. Childhood is a crucial period where we need to pay some extra attention for the nutritional needs and nutritional care of a child, as it acts as a strong pillar for his/her growth and development and prevention of malnutrition. Despite many medical advances over the past 20 years, the prevalence of malnutrition among hospitalized children has not decreased. Since the staff nurses spent more time with patients than any other healthcare workers and the patient recovery is greatly affected by the quality of care these nurses provide to their patients in all the aspects of care, including the nutritional aspect. Present study was conducted to assess the Nurses’ Knowledge, Attitude and Practice towards nutritional care of the hospitalized children, in order to ensure quality nutritional care for hospitalized children who are at risk of developing malnutrition or who are already victims of it. A nonexperimental descriptive research design was adopted to carry out the present study on a sample of 40 staff nurses working at a Tertiary care hospital of Karnataka by administering MKAP questionnaire. The results of the study showed that majority of the staff nurses 28(70%) had average knowledge and neutral attitude regarding malnutrition and nutritional care among hospitalized children , while as 7(17.5%) had good knowledge and positive attitude and 5( 12.5%) of them had poor knowledge and negative attitude regarding malnutrition and nutritional care among hospitalized children.

It has been clearly established that organic matter provides crops with not only nutrients, although in a lower proportion compared to mineral fertilizers, it releases them slowly and gradually. In addition, it also improves the other characteristics of the soil and thus further conditions the fertility of the soil. Consequently, the study of organic manure should not only be limited to the analysis of its effects on the development and yield of crops, it should also extend to the examination of its impact on the maintenance or increasing soil fertility.

The study was conducted for the identification of selected species of family sphingidae through DNA Barcoding in Mt. Kitanglad Lirongan, Lantapan, Bukidnon, Philippines. Thirteen species were collected namely: Acherontia lachesis, Agrius convolvuli, Ambulyx staudingeri, Amplypterus panopus mindanaoensis, Daphnis hypothous, Gnathothlibus erotus erotus, Hippotion brunneum, Hippotion echeclus, Psilogramma menephron, Theretra nessus, Theretra rhesus, Theretra manilae and Theretra sugii. Isolation of the genomic DNA was carried out using the QIAGEN Blood & Tissue Kit. Mitochondrial cytochrome oxidase (COI) gene amplification was carried out using LepF1 (ATTCAACCAATCATAAAGATATTGG) and LepR1 (TAAACTTCTGGATGTCCAAAAAATCA) primers producing 656-666 base pairs were obtained from 30 samples of sphingid moth species. BLAST analyses were able to identify sphingid to the species level. BLAST hits of COI gene sequence of all 10 species ranged from 95%-99% similarity. Maximum likelihood (ML) and Bayesian inference (BI) was used to examine phylogenetic signals in COI with the highest bootstrap values. Sphingid moths formed a monophyletic group based on the clade.
