Disaster Risk Management and Korean Policies
In the past, developing countries such as Korea lacked guidelines for exploring effective policies for disaster-resilient growth, resulting in unnecessary sacrifices in terms of time, resources, and human capital. Through the lessons learned by Korea, currently developing countries facing socio-economic development can build disaster resilience without sacrifices. Utilizing Korea's sound practices and institutional reforms, this course provides a valuable roadmap to prevent and mitigate the catastrophic effects of disasters. This course also provides insightful inspiration about what are the characteristics and the historical path of major disasters; how major disasters arise and affect policy changes; how science and technology can be used to explore and find solutions to complex tasks; and especially, what nations and institutes need to do reduce disaster risk and mitigate death and economic turmoil in the wake of disasters. Throught this, students will be able to explain not only what is disaster risk management but also what must be done for a disaster resilent future.
Advanced Reproducibility in Cancer Informatics
This course introduces tools that help enhance reproducibility and replicability in the context of cancer informatics. It uses hands-on exercises to demonstrate in practical terms how to get acquainted with these tools but is by no means meant to be a comprehensive dive into these tools. The course introduces tools and their concepts such as git and GitHub, code review, Docker, and GitHub actions. Target Audience The course is intended for students in the biomedical sciences and researchers who use informatics tools in their research. It is the follow up course to the Introduction to Reproducibility in Cancer Informatics course. Learners who take this course should: - Have some familiarity with R or Python - Have take the Introductory Reproducibility in Cancer Informatics course - Have some familiarity with GitHub Motivation Data analyses are generally not reproducible without direct contact with the original researchers and a substantial amount of time and effort (BeaulieuJones, 2017). Reproducibility in cancer informatics (as with other fields) is still not monitored or incentivized despite that it is fundamental to the scientific method. Despite the lack of incentive, many researchers strive for reproducibility in their own work but often lack the skills or training to do so effectively. Equipping researchers with the skills to create reproducible data analyses increases the efficiency of everyone involved. Reproducible analyses are more likely to be understood, applied, and replicated by others. This helps expedite the scientific process by helping researchers avoid false positive dead ends. Open source clarity in reproducible methods also saves researchers' time so they don't have to reinvent the proverbial wheel for methods that everyone in the field is already performing. Curriculum The course includes hands-on exercises for how to apply reproducible code concepts to their code. Individuals who take this course are encouraged to complete these activities as they follow along with the course material to help increase the reproducibility of their analyses. **Goal of this course:** To equip learners with a deeper knowledge of the capabilities of reproducibility tools and how they can apply to their existing analyses scripts and projects. **What is NOT the goal of this course:** To be a comprehensive dive into each of the tools discussed. . How to use the course Each chapter has associated exercises that you are encourage to complete in order to get the full benefit of the course This course is designed with busy professional learners in mind -- who may have to pick up and put down the course when their schedule allows. In general, you are able to skip to chapters you find a most useful to (One incidence where a prior chapter is required is noted). Each chapter has associated exercises that you are encourage to complete in order to get the full benefit of the course
The Science of Gastronomy
This course introduces several basic scientific principles underpinning the methodology of cooking, food preparation, and the enjoyment of food. All topics covered have a strong basis in biology, chemistry, and physics application. Among others, they include the consumption of cooked food, the physiological and evolutionary implications of the senses, geographic and cultural influences on food, and the rationale behind food preparation. We will also discuss issues such as coupling of senses to improve sense stimulation; altering flavor by chemical means, and modification of the coloration to improve the appearance of dishes. Following the video demonstrations of the scientific principles of cooking, you will learn to recognize the key ingredients and their combinations for preparing good healthy food. You will also be asked to try out and practice specific cooking principles through the weekly assignments; analyze your data and make comparisons of your experiences with others. At the end of this course, you will be able to: - appreciate the scientific basis of various recipes. - develop your own recipes by integrating some of the scientific principles into new dishes. - recognize the influence of the material world on human perception from the different senses. - appreciate the art of integrating science into cooking and dining.
