CPU students’ awareness of, attitude towards, and involvement in the spiritual programs of the university and their perceived impact on their lives

Abstract only Full text availableThis study was conducted to determine the students’ awareness of, attitude towards, and involvement in the spiritual programs of the university and their perceived impact on their lives. The one-shot survey was used in the collection of data among the 292 graduating college students in 2010. Data collected were processed and analyzed using Statistical Package for Social Sciences (SPSS). For the descriptive part, the major variables were described using frequency distribution and percentages. The z-test was used to determine significant differences between variables and Chi-square and Cramer’s V were used to determine the relationship between specified variables. Results of the study showed that the respondents are generally female, aged 20 years old and younger, belong to the Colleges of Nursing and Business and Accountancy, graduates of public high schools located either in the cities or towns and living with their parents or staying in boarding houses while studying at CPU. The University Church, respective College of the respondents, Department of Religion and Ethics, College of Theology, and, Chaplain’s Office were the offices that offer spiritual programs as perceived by students. Bible study, Christ Emphasis Week Convocations and Devotionals are the major spiritual programs done by the University. Emergency Response Team, CPU Pastor’s Kids, Campus Crusade for Christ, Student Nurses Association of the Philippines, and, Campus Bible Fellowship are the campus organizations which help the students in their spiritual life. The respondents’ awareness of spiritual programs is determined by their sex, age, and college to which they belong. The students have favorable attitude towards the spiritual programs of the university in all areas, namely, role of faculty and staff, role of religious activity, necessity of the program and role of CPU as a whole. Irrespective of their sex, age, college, type and location of high school where they graduated and living arrangement while studying at Central Philippine University, students are more likely to have a favorable attitude towards spiritual programs offered by the university. The location of high school where respondents graduated and college to which the respondents belong determined their involvement in campus organizations while their sex, age, and college determined their involvement in spiritual activities. Majority of the respondents believed that their spiritual life had been changed because of exposure to the different spiritual programs and activities in the university. Only location of high school where respondents graduated is significantly associated with the perceived impact of spiritual programs on their lives. The attitude of the respondents is a determinant of the perceived impact of these spiritual programs on their lives.Central Philippine UniversityIncludes bibliographical reference

How well do Engineers teach? Do background, experience and commitment matter?

Dissertation abstractThis study aimed to find out the knowledge about teaching strategies, career commitment and teaching competence of engineer-teachers in engineering schools in Panay. In consonance with the objectives of the study, it was hypothesized that the levels of the continuing education experiences, knowledge about teaching techniques, career commitment and teaching competence of the engineer-teachers vary according to their sex, age and civil status and their continuing education experiences and knowledge about teaching techniques are related to their career commitment and teaching competence. This study made use of the descriptive-relational method with one-shot survey design. Complete enumeration of the sixty-five full-time engineer-teacher faculty members of these schools who participated served as the respondents of the study. Data were collected using a questionnaire and were computer-processed using the Statistical Package for the Social Sciences (SPSS) for MS Windows 10.0 software. The profile of the respondents were analyzed using percentages and frequency distribution. The variation in the levels of the continuing education experience, knowledge about teaching techniques, career commitment and teaching competence of the engineer- teachers according to their sex, age and civil status and the relationship between their career commitment and teaching competence and their continuing education experience and knowledge about teaching techniques and methods were analyzed using z-test for difference between proportions, Gamma and Pearson’s r. Findings The engineer-teachers of engineering schools in Panay were generally males, married and middle-aged. The engineer-teachers had an average of 15.192 years of teaching experience; had attended an average of three trainings attended in the last five years; had three and a half years of professional experience; and, had earned an average of 8.83 units in education. The engineer-teachers had an excellent knowledge about the different teaching techniques and methods with a mean score of 13.03 out of 15 items test about techniques. Specifically, their knowledge about cooperative learning, experimenting, discussion, student research, team teaching, problem solving, peer tutoring, field study, and lecture was high. The engineer-teachers also had a high level of career commitment. The same is true with their level of commitment in three sub-categories namely: dedication, loyalty, and identification. Moreover, the majority of them had an outstanding level of teaching competence. The data further show that the number of years of teaching experience of the engineer-teachers did not significantly vary according to their sex, age and civil status. There was also no big disparity in the number of relevant trainings attended; length of professional experience; and, in the number of education units earned before teaching in the College of Engineering between sex groups, age groups and civil status groups. On the other hand, there were more male than female engineer-teachers who had excellent knowledge about teaching techniques, while there were more female than male engineer-teachers who had very good knowledge of teaching techniques. Almost all of the engineer-teachers, regardless of sex, had a high level of career commitment in terms of dedication and loyalty to their work. However, the difference between proportions of male and female engineer-teachers in the high category of level of career commitment in terms of identification revealed that female engineer-teachers have a little higher level of identification with their work as teachers and over-all commitment to their teaching career in the College of Engineering than the male engineer-teachers. Almost the same proportion of the engineer-teachers had very satisfactory and outstanding teaching competence regardless of their continuing education experiences, such as attendance to relevant trainings; number of years of professional experiences before teaching; and number of education units earned. The study further revealed that the longer the engineer-teachers’ stay experience in teaching, the more they are dedicated to their teaching profession. Their loyalty to the teaching profession peaks at their 10th -19th year in teaching. The more experienced they are, the more they are committed to their teaching profession. The engineer-teachers’ level of career commitment varied according to their attendance in relevant trainings. Those who had attended trainings were more loyal to their schools than those who had not attended any training. No significant difference however was noted between the two groups in their level of commitment in terms of dedication, identification and over-all commitment. Furthermore, no significant difference in the level of their commitment in terms of dedication, loyalty, identification and over-all commitment was also noted between those who had professional experience prior to their teaching career and those who had no professional experience. The data further show a significant relationship between age and teaching competence of the engineer-teachers. There were more female than male engineer teachers who had outstanding teaching competence, while there were more male than female engineer-teachers who had very satisfactory teaching competence. As to civil status, no big difference in the teaching competence was noted between the single and the married engineer-teachers, although, there were more single than married engineer teachers with outstanding teaching competence. The findings also revealed a positive relationship between career commitment and teaching competence of the engineer-teachers. Those with high level of dedication, loyalty, identification and over-all commitment to their teaching profession, also had high teaching competence. Conclusions On the basis of the findings of this study, it is reasonable to conclude that: Engineer-teachers of Panay are mostly males, married, middle-aged, experienced teachers with professional experience, highly committed and competent in their teaching career, and had excellent background in teaching techniques. The number of years of teaching in the college of engineering, number of years of professional experience prior to teaching and number of units in education earned varied according to the age of the engineer-teachers. The middle-aged and older engineer-teachers had an edge over the younger ones in terms of teaching and professional experience, as well as in equipping themselves for their teaching career such as having units in education. The level of knowledge about teaching techniques of engineer-teachers varied according to their sex, with male engineer-teachers having a better grasp of teaching techniques that are best suited for engineering students. The teaching competence of the engineer-teachers varied according to their age, in favor of the older ones. The older one becomes, the more competent he gets. Career commitment, specifically, the engineer-teachers’ identification with their work as teachers is related to their teaching competence. The engineer-teachers’ identification with their work as teachers helps them become good teachers.Includes bibliographical referencesDoctor of Education (Major in Educational Administration and Supervision

Design and development of automatic battery charger with controller for battery charging station

The study aimed to design and construct a locally-made battery charge controller for the Battery Charging Station (BCS) project implemented by Central Philippine University-Affiliated Non-conventional Energy Center (CPU-ANEC). The battery charge controller was designed only to protect the battery from over-charging. The functionality of the charge-controller was tested using a solar panel and a battery. The charging current was controlled by the PWM circuit. During charging, the output of the PWM circuit was both set approximately to ten percent (10%) duty cycle for charging ninety percent (90%) duty cycle for trickle charging. The output waveform and the duty cycle of the PWM circuit were checked using the oscilloscope. Testing of the charge-controller was done for four days of continuous operation to ensure the reliability of the system. Based on the test results, when the duty cycle was ten percent (10%), the green LED lighted-up and the ammeter indicated maximum charging current, while for the ninety percent (90%) duty cycle, a yellow LED light-up indicating minimum current. The red LED light-up when the polarity of the battery was reversed, while the orange LED lightedup only when the battery state of charge was empty. These test results show that the battery charge-controller worked as expected by meeting the required design parameters. The unit is now ready for use

Level of harmonics produced by the variable frequency drive controller used in the induction type water pump motor of Central Philippine University

Abstract onlyThe determination of the level of harmonics produced by the variable frequency drive (VFD) controller used to control the induction-type water pump motor at the water pumping station of Central Philippine University (CPU) was focused specifically on the electrical noise or harmonic level generated by the controller in terms of its amplitude and frequency. The level of harmonic content was acceptable based on the IEEE Std 519- 1992 of no more than 5% with the use of the controller and its effects on electronics and electrical systems connected in the same pick off point. It was also determined whether the system would significantly improve motor performance. Lastly, it was determined whether the system would significantly reduce energy consumption. Based on the results of the tests, the harmonics of the supply voltage at no load was 2.25%. During the system operation where a five (5) Hp induction type motor load was controlled direct-on-line (DOL), the harmonics generated was about 2.10%. However, by using the controller, it was found out that there was an increase in the amplitude and the number of harmonics present in the system. The harmonics produced at the source terminal with controller was about 3.93 %, showing an increase of 1.83% compared to without the use of the controller. However, the increase is minimal because 3.93 % is within the acceptable limits of 5% for electronics circuits and systems. However, this is not acceptable for medical and other related highly sensitive instruments, which require a THD of not more than 3%. In contrast to this, the harmonics generated at the load terminal was about 8.42%, which was higher compared to the THD at the input terminal and was very much higher than the required allowable level. The controller produced a significant level of harmonics that could cause interference to nearby electronic appliances that are sensitive to electrical noise within very close proximity. Nevertheless, this noise or harmonic generated was not significantly induced at the source terminal. Furthermore, there was no reduction on the energy consumption with the use of the controller over the DOL control mode. In contrast, the use of the controller gave the following benefits: it eliminated the very high current surges and sudden high starting torque during the motor start up; balanced the motor supply between phases; and, caused an increase in the revolution-per minute (rpm) of the motor thereby improving the performance of the motor. The same controller could be put to good use with some of the other pump motors around the campus.Includes bibliographical reference

Level of harmonics produced by variable frequency drive controller used in induction type water pump motor

This study focuses specifically on the determination of electrical noise or harmonic level generated by the variable frequency drive controller in terms of its amplitude and frequency. The central area of concern is the effect of harmonics on the power quality of the electrical supply of Central Philippine University at the point of the pump-motor equipment. Based on the results of the tests, the harmonics of the supply voltage was 2.25%. Running the 5-HP motor directly produced a lower harmonics of 2.10%. When the controller was used to run the motor, the controller in itself produced a significant level of harmonics of 8.42%which interferes with nearby electronic appliances within a very close proximity. A substantial part of the harmonics produced by the controller is filtered from going out of the device itself, so that the harmonic level at the source terminal was about 3.93 %, showing an increase of 1.83% compared to running the motor without the use of the controller. The value is within the acceptable limits of 5% for electronic circuits and systems, but not acceptable for medical and other related highly sensitive instruments, which require a total harmonic distortion (THD) of not more than 3%

Design and development of automatic battery charger with controller for battery charging station

Abstract onlyThe study aimed to design, develop, and constructs a locally-made battery charge controller for Battery Charging Station (BCS) project implemented by Central Philippine University-Affiliated Non-conventional Energy Center (CPU-ANEC). The charge controller is made up of thirteen blocks, Blocking diode, Shunt control element, trickle charge indicator, pulse width modulator (PWM), high voltage reconnect (HVR), high voltage disconnect (HVD), charge indicator, low voltage disconnect (LVD), low voltage reconnect (LVR), load controller, full charge indicator, and reverse polarity protection. The functionality of the charge controller was tested using solar panel, charge controller and the battery. The charging status and the battery state of charge was determined using the four light emitting diode (LED) indicator with four different colors, green LED for charging, Yellow LED for trickle charging, Orange LED for low battery voltage or LVD, and the red LED is for reverse polarity. The charging current are controlled by the PWM circuit, during charging the output of the PWM circuit was set to approximately ten percent (10%) duty cycle and approximately ninety percent (90%) duty cycle for trickle charging. To test PWM circuit, oscilloscope was used to display the output waveform of the PWM circuit and the checking of the duty cycle. Base on the result of testing, when the duty cycle is ten percent (10 %), the green LED light-up and ammeter reads maximum charging current, and if the duty cycle is ninety (90 %), yellow LED light-up, ammeters reads minimum current. The red LED will light-up only if the polarity of the battery is reverse, and the orange LED will light-up if the battery state of charge is empty. The testing of the charge controller was done for four days of continuous operation to ensure the reliability of the system. Base on the result of testing and evaluation, the charge controller worked as expected, working normally and the charge controller met the required parameters and is ready for use.Includes bibliographical reference
