Hands-on exercises and computer visualization programming provide a fertile field for enabling engineering students to understand the wealth of underwater industry and equip them with the related knowledge, skills, and abilities needed to work in them. To this end, Remotely Operated Vehicle (ROV) serves as a valuable tool in assisting students in Engineering, Technology, and Science to understand the manufacturing assembly design process. The purpose of this paper is to investigate the challenges and obstacles of the manufacturing assembly design of the ROV. In doing so, the paper aims to enhance students’ understanding of the underwater ROV manufacturing assembly process. Another goal of this paper is to assist students to participate and compete in the upcoming Marine Advanced Technology Education (MATE) annual competition. The paper will test the impact of these experimentations to the knowledge base about engineering manufacturing courses for College of Engineering at University of Hail (UoH).
Making use of hermeneutic phenomenology and morality critique as methodological navigation points, this paper challenges the illusory prestige and power of normative orders in presenting themselves to every successive generation as the best possible likenesses of and most believable blueprint(s) for eudaimonia (the good life). By implication, it also challenges the education systems that are designed to keep these normative orders alive. It is suggested that what education needs is not morals and ethics, but a pedagogy of discernment that will teach pupils to keep their eyes open and to recognise the tragic truth that normative systems maintain themselves at the cost of wiping out the ontic truth of singularisation, mortality, as well as the ultimate non-normalisability of the human condition, namely that although we are capable of immense love and sensitivity, we are also capable of greed, hatred, brutality, rape, murder and war.
This paper reports on two historically disadvantaged South African schools who managed to overcome the perennial problem of the achievement gap (as measured by matric results) between the historically advantaged and the historically disadvantaged schools. A qualitative, narrative research design, entailing interviews for exploring and studying the view of the students, were used. From the data analysis the following themes emerged as sets of factors that, in the opinion of the learners, had contributed to the two schools’ bridging of the achievement gap: a supportive teaching and learning environment, teacher effectiveness, collaborative relationships, positive school climate and principals’ instructional leadership. These factors are discussed, and are compared/contrasted to and synthesised into what appears in the scholarly literature as factors explaining achievement differentials between different students and different schools. This research cautions educational leaders and scholars not to attach too much value to theories such as socio-economic and cultural reproduction in as far as they portray the socio-economic descent of learners as deterministic with respect to their achievement levels at school. Rather than such a fatalistic view, this study tends to support the more voluntaristic view that intra-school factors are significant, and can potentially overcome extra-school factors.
La investigación científica está dedicada, regularmente, a resolver problemas de las industrias; pero dentro de los confines de una sola disciplina. Esta característica reduce la visión y valoración de los impactos tecnocientíficos en sociedad y ecosistemas. Sin embargo, la crisis socioecológica ha catalizado una tendencia de investigación llamada transdisciplina, un proceso de solución para la complejidad, generalmente, relacionada con la incertidumbre, la inseguridad y la ausencia de protección. Este documento reflexiona sobre la trascendencia de hibridar las fronteras disciplinarias a través del diálogo donde estén incluidos los saberes tradicionales en la generación de alternativas.
Synthesis of 1-(3-phenylpropyl)pyridazin-1-ium bromide 2, a novel ionic liquid (IL), was achieved using an efficient, green ultrasound-assisted process. The structure was characterized by FT-IR, 1H NMR, 13C NMR, and mass spectrometry. The cyclic voltammetric behavior of this new ionic liquid 2 (5×10-5 mol L-1 and 50 mV/s scan rate) was investigated in Britton-Robinson (B-R), acetate and phosphate buffers at pH 3. A broad cathodic cyclic voltammetric peak at E1/2= −780 mV was recorded using hanging mercury drop, glassy carbon and graphite electrodes vs. Ag/AgCl reference electrode. Electrochemical reduction of the analyte was irreversible and diffusion-controlled. High performance liquid chromatography (HPLC) of 2 was investigated using a C-18 (5 µm) column for separation from interferences. A mobile phase containing methanol: acetonitrile: phosphate buffer at pH 3 (30:30:40 v/v/v%) was used, and elution of 2 was monitored with UV detection at 254 nm. The retention time of this compound was recorded to be 2.152 min.
Resumen\nLa gestión y participación de cada uno de los mexicanos en lo que respecta a mantener el equilibrio en estilo de vida y salud, se constituye en derechos y obligaciones para el binomio gobierno–ciudadano, es decir, desde la corresponsabilidad, ambos con la obligación de hacer por la salud, por lo que el objetivo del presente ensayo se centró en incursionar en la generación de conocimiento respecto a gestión en salud a partir de una revisión bibliográfica con énfasis en las funciones esenciales de la salud pública, para proponer estrategias orientadas a mejorar en estilos y calidad de vida, y de ahí en el estado de salud de la población. Las instituciones de gobierno requieren estimular mediante la gestión de calidad de sus servicios de salud, en corresponsabilidad del esfuerzo compartido con la participación comunitaria con énfasis en la transformación de los estilos de vida, por lo que, personas con estilo de vida deficiente representan en sí un reto social compartido.
The purpose of this study is to investigate the relationship between job satisfaction and organizational commitment of the assistants and faculty at the University of Payam Noor province of Yazd. The population of this study, residents and faculty members, including 80 in Yazd University of Payam Noor of these, 62 patients from 10 centers/ units message light, has responded to the questionnaire survey. To collect information on job satisfaction (Visoky and chrome, 1993), which includes five dimensions (the nature of work satisfaction, satisfaction with supervisor, colleague satisfaction and advancement and promotion, payment) is used. The Organizational Commitment Questionnaire (Modaee, Styrz, Porter, 1979), which consisted of 13 questions on a Likert scale, is applied. Analysis of data from the questionnaires using descriptive statistics, percentage, and frequency, mean dimensions of job satisfaction and organizational commitment and inferential statistics: Correlation coefficient for the hypothesis test is conducted using the spss 10 software. The findings show that job satisfaction and organizational commitment in the light of a significant relationship exists between faculty messages. It also shows faculty members PNU of job satisfaction is relatively high (133.05), especially after contact with colleagues, and the nature of the job, had the lowest level of satisfaction was related to promotion (15.83). Based on average organizational commitment (50.69), people can say organizational commitment is moderate. Between age, gender, academic rank and years of service with the main variables there is no significant difference.
The aim of the investigation consists in describing the toxicity impact and knowledge of the utilization of pesticides by farmers through the analysis of discourses and community intervention in Metztitlan Hidalgo, Mexico. A qualitative intervention study was realized with a phenomenological-ethnomethodological pragmatic design through the analysis of the discourse of 4 people, where 3 of them had been intoxicated by pesticides and 1 who has vast experience in the utilization of these products. In three phases, a contextual tour was realized. Photographs were taken of the agricultural context when the pesticides were being applied, depth interviews were applied, and finally categories were structured for the analysis of the discourses. Exclusive irrigated crops were observed. Utilizing water from River, the applicators mix the pesticides in a plastic barrel and then application tanks are filled. Their hands are even used to verify the filling. They don’t count with the minimal protection for the managing and application of the pesticides. The empty containers thrown on the ground indicate the type of pesticides used by farmers. The people intoxicated have required hospitalization and it seems that there are even deaths due to the exposition of these products. The farmers-applicators of pesticides don’t know the risks that they are exposed to. This is correlated with the low level of school education that they have and that there doesn´t exist accessibility to buy equipment for personal security.
