Experience is an important requirement to apply for a qualified job. While employers need to find workers with the required skills, education institutions must design curricula which provide the skills demanded by the job market. Besides, along their careers, workers need to make good choices on continuing education courses. Current Bachelor and Master degrees follow programs which attempt to offer a practical perspective, but still from the academia point of view. To bridge the gap between academia and industry, University Extension Diploma in Food Technology (DEUTA) deepens into the Food sector seeking professional capacitation of participants. This is achieved by both first-hand know-how of food sector professionals and academics, along with an internship period in a food company. This paper reports the experience for more than fifteen years of this Diploma. Curriculum, students background, food sectors where internships are taken, student’s opinion on the course management as well as on issues related to employability, development of professional skills and life-long learning are discussed. The analysis demonstrates how collaborative courses strengthen academia-industry bonds, and employability is boosted thanks to internships and the network created. This experience may be extrapolated to many sectors other than food, such as the chemical, environmental or biotechnological, and may help lecturers and institutions organize similar courses or diplomas to prepare competent and efficient technical workers, as well as help students and professionals orient their training and continuing education choices.

经验是申请一份合格工作的重要要求。虽然雇主需要找到具有所需技能的工人,但教育机构必须设计课程,提供就业市场所需的技能。此外,在他们的职业生涯中,工人需要在继续教育课程上做出正确的选择。目前的学士和硕士学位遵循的课程试图提供实用的观点,但仍然是从学术的角度来看。为了弥合学术界和工业界之间的差距,大学食品技术扩展文凭(DEUTA)深入到食品行业寻求专业能力的参与者。这是通过食品行业专业人士和学者的第一手知识以及在食品公司的实习时间来实现的。本文报告的经验,这一文凭超过15年。课程设置、学生背景、实习食品行业、学生对课程管理的意见以及与就业能力、专业技能发展和终身学习有关的问题进行了讨论。分析表明,合作课程如何加强了学术界与工业界的联系,由于实习和建立的网络,就业能力得到了提高。这一经验可推广到食品以外的许多部门,如化学、环境或生物技术部门,并可帮助讲师和机构组织类似的课程或文凭,以培养称职和高效的技术工人,并帮助学生和专业人员确定其培训和继续教育选择的方向。

Multidisciplinary teams often undertake engineering projects beyond their original discipline involving different kinds of risks. Risk perception is an inherent and embedded part of the decision-making process, which depends on the personal background and instinctive attitudes or behaviors. Process safety and risk analysis training for engineers, and education for engineering students, provide valuable tools seeking safer workplaces; however, personnel’s risk perception is commonly neglected. This paper analyzes the risk perception and appetite of undergraduate engineering students in Colombia based on a survey strategy and a weighted-approach following a Factor Analysis. The survey considered financial, social, physical, and professional risks, and four main reasons for risk-taking or risk-avoiding actions. The Factor Analysis allows us to classify the students tendency as risk-averse o risk-prone, and propose didactic teaching planning using a modular toolbox for process safety education, based on skills identified for junior engineers in Colombian Oil & Gas Industry. A total of 465 engineering students from 12 Colombian universities completed the survey in 2016. The results suggest that risk perception depends on the location, possible risk training, and accessible information. The obtained factors allow describing the students’ overall risk profiles, which can serve as an input for refining the content and curriculum content of current engineering programs regarding process safety. Improving the training of risk management in the engineering curriculum will benefit upcoming multidisciplinary teams in high-risk industries.

多学科团队经常承担超出其原始学科的工程项目,涉及不同类型的风险。风险感知是决策过程中固有的和嵌入的一部分,它取决于个人的背景和本能的态度或行为。为工程师提供过程安全和风险分析培训,为工程专业学生提供教育,为寻求更安全的工作场所提供宝贵的工具;然而,人员的风险感知往往被忽视。本文基于调查策略和因子分析后的加权方法,分析了哥伦比亚工科本科生的风险感知和偏好。该调查考虑了财务、社会、身体和职业风险,以及冒险或规避风险行为的四个主要原因。因子分析使我们能够将学生的倾向分为风险厌恶型和风险倾向型,并根据哥伦比亚石油公司初级工程师的技能,使用模块化工具箱提出教学计划,用于过程安全教育。天然气工业。2016年,来自哥伦比亚12所大学的465名工科学生完成了这项调查。结果表明,风险感知取决于地点、可能的风险培训和可获得的信息。获得的因素允许描述学生的整体风险概况,这可以作为精炼当前工程项目关于过程安全的内容和课程内容的输入。改善工程课程中的风险管理培训将有利于未来高风险行业的多学科团队。

Before the pandemic, distance learning was not a widely adopted option for science and engineering programs where in some courses, such as chemistry, electromagnetism, or fluid mechanics, etc., attending to laboratories and workshops was in most cases mandatory. The lockdown forced us to innovate, searching alternative ways to teach experimental phenomena, suddenly replaced with simulation science and technology, subjects that although rely on computers, also suffered changes from the transition. In this contribution, we propose an undergraduate course on simulation for chemical engineering, departing from the fact that modeling, and simulation are multipurpose and multidisciplinary tools. The course aims to reinforce the concepts of dynamical systems by using analogies between process engineering examples and other disciplines, particularly, epidemiology. For this purpose, a final project on modeling the dynamics of the COVID 19 pandemic in Mexico was designed and validated with a public database from the Mexican Secretariat of Health. By doing this, the students got in touch with the evolution of the dynamics outside of school hours, since it was common to see weekly updates and extrapolation trends of the pandemic, thus applying their skills to the final project. It was found that success factors were the use of official data, the use of Graphical User Interfaces to explore diverse simulation scenarios and the final project. The transition to the Distance Learning faced several challenges that were partially coped with the redesign of the course.

在大流行之前,远程学习并不是科学和工程课程的广泛选择,因为在化学、电磁学或流体力学等某些课程中,参加实验室和讲习班在大多数情况下是强制性的。封锁迫使我们创新,寻找其他方法来教授实验现象,突然被模拟科学和技术所取代,这些学科虽然依赖于计算机,但也遭受了转型的变化。在这篇文章中,我们提出了一门化学工程模拟的本科课程,从建模和模拟是多用途和多学科工具的事实出发。本课程旨在透过过程工程范例与其他学科,特别是流行病学之间的类比,强化动力系统的概念。为此,设计了一个关于墨西哥COVID - 19大流行动态建模的最终项目,并利用墨西哥卫生秘书处的公共数据库进行了验证。通过这样做,学生们在课余时间了解了动态的演变,因为每周都会看到疫情的更新和推断趋势,从而将他们的技能应用到最终项目中。结果发现,成功的因素是使用官方数据,使用图形用户界面探索不同的模拟场景和最终项目。向远程学习的过渡面临着一些挑战,这些挑战部分是通过重新设计课程来应对的。

Teaching the various contents of signaling in molecular biology to students is challenging. The mechanistic details between the ‘wiring diagram’ of signaling and the cellular outcomes are usually missing in textbooks. Students always feel exhausted when they have to complete the mandatory courses on molecular biology. In current work, MATLAB simulations were introduced to interpret the intrinsically dynamic mechanisms of key signaling pathways. The theoretical basis was first introduced and then two examples related to intrinsic apoptosis and p53 pathway were provided. The high-performance of MATLAB visualization can also help students improve their experiences in learning molecular biology. The strategy of using MATLAB simulations was primarily designed for illustrative purposes and some simply exercises were given for students. The response of students to the questionnaire is generally more positive concerning the suitability of using MATLAB simulations. Most students were interested in the molecular biology courses with modeling contents. We argue that the computational tool may be a useful alternative for engaging students and helps reinforce understanding of signaling pathways.

向学生教授分子生物学中信号传导的各种内容是具有挑战性的。信号“接线图”和细胞结果之间的机制细节在教科书中通常是缺失的。当学生们必须完成分子生物学的必修课程时,他们总是感到筋疲力尽。在目前的工作中,引入MATLAB仿真来解释关键信号通路的内在动态机制。首先介绍了理论基础,然后给出了两个与细胞内禀凋亡和p53通路相关的例子。MATLAB可视化的高性能也可以帮助学生提高学习分子生物学的体验。使用MATLAB仿真的策略主要是为了说明目的,并为学生提供了一些简单的练习。对于使用MATLAB仿真的适用性,学生对问卷的反应普遍较为积极。大多数学生对具有建模内容的分子生物学课程感兴趣。我们认为,计算工具可能是一个有用的替代参与学生,并有助于加强对信号传导途径的理解。

STEM programs and companies continue to struggle to find and retain talent from underrepresented minorities. This is often due to difficulty retaining these students in university programs, despite similar initial enrollment rates. Students of Hispanic descent are the fastest growing group of students in the United States education system. As more Hispanic students begin to study STEM and more universities become Hispanic-serving institutions, STEM curricula should adapt to better serve this group. In this article, we discuss how prominently including the work of minority scientists and engineers in the classroom can bolster students of color. Next, we re-introduce the work of noted Hispanic scientists Luis Miramontes and Mario Molina and technology from ancient Mesoamerican cultures. Finally, we show how educators can easily use these scientists’ work to increase representation in coursework without drastically changing their lecture notes.

STEM项目和公司仍在努力从未被充分代表的少数族裔中寻找和留住人才。这通常是由于很难在大学课程中留住这些学生,尽管最初的入学率相似。西班牙裔学生是美国教育系统中增长最快的学生群体。随着越来越多的西班牙裔学生开始学习STEM,越来越多的大学成为为西班牙裔服务的机构,STEM课程应该适应更好地为这一群体服务。在这篇文章中,我们讨论了在课堂上突出少数族裔科学家和工程师的工作是如何支持有色人种学生的。接下来,我们将重新介绍著名的西班牙裔科学家Luis Miramontes和Mario Molina的工作,以及来自古代中美洲文化的技术。最后,我们展示了教育工作者如何可以轻松地使用这些科学家的工作来增加课程作业中的代表性,而无需大幅更改他们的课堂笔记。

Due to the steadily rising number of students and the simultaneous reduction in practical lessons in study programs, the need for alternative learning resources is increasing. In this work, a method is described which allows real laboratory equipment to be represented as web-based models, using a stirred bioreactor as an example. The bioreactor model that was developed allows students to explore the design and operation of stirred bioreactors independently of time, location and end device. Information associated with each bioreactor component is displayed on the model to help students become familiar with different bioreactor setups. Computational fluid dynamics (CFD) simulations were embedded to enable students to understand the influence of different stirrers on flow behavior in the bioreactors. This online tool prepares students for subsequent practical work with bioreactors in the laboratory.

In the recent 39 years, China colleges and universities have developed drastically. However, the colleges’ laboratory accidents also rise significantly. This paper analyzed 197 China college accidents. The results show that the highest percentage of safety accidents are hazardous chemicals. Most of the injured parts of the 416 casualties are concentrated in the front upper body. The author finds that there is a certain correlation between the percentage of accidents and the number of students, as well as the number of scientific research activities. Based on the findings, the author points out: firstly, the college safety department should build a laboratory safety information sharing and analysis platform. The dynamic information includes hazardous chemicals, students, dangerous equipment, research experiments, etc. Secondly, China colleges and universities should build a laboratory safety education system with Chinese characteristics, incorporating laboratory safety education into the training of students. Finally, it is urgent to establish a professional team to fully implement the laboratory safety responsibility system; to establish a laboratory hierarchical and classified management system and to improve experiment project risk assessment and control; to carry out a special inspection on laboratory safety; to carry out standardized construction and to establish standardized process management procedures.

在最近的39年里,中国的高校得到了巨大的发展。然而,高校实验室事故也明显上升。本文对197起中国高校事故进行了分析。结果表明,危险化学品的安全事故比例最高。在416名伤亡人员中,大部分受伤部位集中在上半身前部。笔者发现事故发生率与学生人数、科研活动次数有一定的相关性。基于调查结果,作者指出:首先,高校安全部门应建立实验室安全信息共享与分析平台。动态信息包括危险化学品、学生、危险设备、研究实验等。其次,中国高校应构建具有中国特色的实验室安全教育体系,将实验室安全教育纳入学生的培养中。最后,迫切需要建立专业团队,全面落实实验室安全责任制;建立实验室分级分类管理制度,完善实验项目风险评估与控制;开展实验室安全专项检查;开展标准化建设,建立标准化流程管理程序。

Hands-on experience in the laboratory is essential in chemical engineering education to enhance the understanding of abstract theories and their effect on chemical processes. In this work, we describe a laboratory class, which combines some of the main engineering concepts into a set of hands-on experiments and simulations. Students are introduced to an iodine clock reaction performed in multiple different reactor types and are instructed to determine the reaction kinetics. Subsequent analysis of the experimental data in Python teaches basic programming skills and the concepts of numeric integration and optimization. Finally, a digital twin of one of the reactors is developed in COMSOL Multiphysics to give the students an application-focused introduction to more-dimensional multiphysics modeling. The students thereby get practical insights into the different methods and stages of reactor and reaction engineering. Based on the students’ assignments, we consistently see a deeper understanding of reaction kinetics and reactor engineering than in the accompanying traditional lecture.

在化学工程教育中,为了提高对抽象理论及其对化学过程的影响的理解,在实验室的实践经验是必不可少的。在这项工作中,我们描述了一个实验课,它将一些主要的工程概念结合到一组动手实验和模拟中。向学生介绍在多种不同类型的反应器中进行的碘时钟反应,并指导他们确定反应动力学。随后用Python对实验数据进行分析,教授基本的编程技能以及数值积分和优化的概念。最后,在COMSOL Multiphysics中开发了其中一个反应器的数字孪生,为学生提供了以应用为重点的多维多物理场建模介绍。因此,学生们对反应堆和反应工程的不同方法和阶段有了实际的了解。根据学生们的作业,我们一致看到他们对反应动力学和反应器工程的理解比传统讲座更深入。
