Aberrational Effects for Shadows of Black Holes

In this paper, we discuss how the shadow of a Kerr black hole depends on the motion of the observer. In particular, we derive an analytical formula for the boundary curve of the shadow for an observer moving with given four-velocity at given Boyer--Lindquist coordinates. We visualize the shadow for various values of parameters.Comment: 12 pages, 3 figures; Proceedings of the 524. WE-Heraeus-Seminar held at the Physikzentrum, Bad Honnef, Germany, 17.--23.2.201

GAUGING THE ICT-BASED TEACHING READINESS OF PRESERVICE TEACHERS IN THE LIGHT OF 21ST CENTURY EDUCATION

This triangulation study assessed pre-service teachers of their readiness to functionally utilize Information and Communication Technology (ICT) – based teaching strategies and techniques as corroborated with new graduates’ related experiences.Their knowledge in ICT-based teaching acquired from the educational technology courses in teacher education was correlated with their attitudes and perceptions toward the use of these strategies in causing functional learning, their perceived readiness, and technological practices. Subsequently, issues concerning the use of ICT-based strategies learned in college were sought from graduates of teacher education through exposition of experiences in their respective workplaces.This study ultimately revealed that the educational technology course experiences were not responsive enough to capacitate pre-service teachers to enact ICT-based strategies toward functional learning of their future students. They generally believe that their knowledge, potentials, and skills were not adequate to maximize ICT in designing and implementing curricular programs when they become full-fledged teachers despite their positive views on the benefits of ICT in teaching. New teacher-graduates, meanwhile, experienced limitations on the opportunities to use ICT in teaching due to lack of facilities and available resources to carry out their learned competencies. They also expressed restraint to innovate teaching as they were aghast of the demands of 21st century education. The need to revitalize the teacher education curriculum is, therefore, proposed that should be highly responsive in gearing up the potentials of pre-service teachers on ICT-based teaching in the light of 21st century education

Awareness of Disaster Risk Reduction (DRR) among Student of the Catanduanes State University

The Island Province of Catanduanes is prone to all types of natural hazards that includes torrential and heavy rains, strong winds and surge, flooding and landslide or slope failures as a result of its geographical location and topography. RA 10121 mandates local DRRM bodies to “encourage community, specifically the youth, participation in disaster risk reduction and management activities, such as organizing quick response groups, particularly in identified disaster-prone areas, as well as the inclusion of disaster risk reduction and management programs as part of youth programs and projects. The study aims to determine the awareness to disaster of the student of the Catanduanes State University. The   disaster-based questionnaire was prepared and distributed among 636 students selected randomly from different Colleges and Laboratory Schools in the University The Catanduanes State University students understood some disaster-related concepts and ideas, but uncertain on issues on preparedness, adaptation, and awareness on the risks inflicted by these natural hazards. Low perception on disaster risks are evidently observed among students. The responses of the students could be based on the efficiency and impact of the integration of DRR education in the senior high school curriculum. Specifically, integration of the concepts about the hazards, hazard maps, disaster preparedness, awareness, mitigation, prevention, adaptation, and resiliency in the science curriculum possibly affect the knowledge and understanding of students on DRR. Preparedness drills and other forms of capacity building must be done to improve awareness of the student towards DRRM. The study further recommends that teachers and instructor must also be capacitated in handling disaster as they are the prime movers in the implementation of the DRRM in education. Preparedness drills and other forms of capacity building must be done to improve awareness of the student towards DRRM. Core subjects in Earth Sciences must be reinforced with geologic hazards. Learning competencies must also be focused on hazard identification and mapping, and coping with different geologic disaster

Motivation of Engineering Faculty of the Catanduanes State University Toward works

The graduates of the Catanduanes State University prefer to work abroad and in Metro Manila. There were some who preferred to stay in the province and look for a job. The College of Engineering barely needs additional faculty members, but few are willing to work in the institution. This research sought to determine the unique motivational factors towards work of the faculty of the college and why they are staying in the university. The research was conducted using a qualitative study of the faculty utilizing the questionnaire and interview on the motivation aspect towards work. The faculty of Catanduanes State University- College of Engineering was found to be significantly interested in doing their best and, given the freedom, will perform well. Simple recognition will validate what they have done well and will serve as additional motivation for the faculty. This research also found that organization background, reputation, working environment, harmonious workplace relationship is equally important with the salary

Health and Safety in the Construction Industry in Catanduanes, Philippines

The Island Province of Catanduanes is gaining grounds in the field of construction. The program of the current administration “Build, Build, Build” have taken the construction industry to full blast. Construction, both private and public are evident on every corners of the island. Occupational Safety and Health in construction is often neglected and disregarded. Construction is the one of the most dangerous sectors in health and safety. The government, thru the Department of Labor and Employment had already address the problem by providing safety and health training to the personnel of the construction firm as well as the industry as a whole. But the effort has been far from satisfactory, as construction accident continue to dominate the entire industry. The study aims to awareness of construction safety in Catanduanes. The study focuses on the awareness of workers in construction industry in Catanduanes on Occupational Safety and Health. From the series of interviews and interaction with the workers on site, and upon evaluation of their responses, the researcher finally come up with the conclusion that, the construction workers are aware of the safety and health in constructions but they do not adhere and follow it. Workers admittedly that the reason they are complaisant about following safety and health practices are discomfort, beliefs, and bad habits. The following recommendation were sought based on the results of the interview; 1. Workers must attend or be trained with safety and health. A training that would enable them to understand the safety and health issues and concerns, 2. Workers must be taught with correct attitude towards safety in workplace, 3. They must taught of right things contrary to their old beliefs, 4. Workers must developed good habit and positive outlook in terms of their safety and well-being
