Otak manusia berada di tempat yang paling atas dan ditutupi dengan lapisan-lapisan kulit, tulang, dura, araknoid dan pia. Terdapat lubang tertentu pada tulang untuk membenarkan sambungan antara otak dengan saraf tunjang, saraf dan salur darah. Otak juga dikelilingi oleh cecair yang dinamakan cecair otak. Dengan adanya lapisan-lapisan dan cecair tersebut, maka otak dilihat sebagai organ yang istimewa dan mesti dilindungi dari perkara luaran. Kajian menunjukkan kandungan otak adalah 70% cecair dan 30% pepejal; 60% pepejal otak terdiri daripada lemak. Oleh yang demikian, walaupun cecair otak adalah sedikit, apungan tetap ada di dalam tengkorak otak. Apabila diteliti, posisi otak juga membengkok atau sujud di bahagian tengah otak. Posisi ini dikenali sebagai posisi mikrograviti. Kurangnya kesan graviti disebabkan oleh apungan otak yang mematuhi prinsip Archimedes menyebabkan otak berada dalam posisi tersebut. Apungan ini nampaknya sudah sedia ada semasa proses pembentukan otak atau janin lagi. Seawal proses tersebut, cecair di dalam rahim ibu sudahpun wujud dan memberi kesan apungan kepada sel-sel asas yang berbentuk tiub. Oleh itu, tiub ini juga berada dalam posisi sujud atau posisi mikrograviti. Kajian ke atas proses pembentukan otak dan janin menunjukkan bahawa anatomi otak yang berada bersebelahan dengan ruang cecair otak merupakan kawasan yang penting dan berkait rapat dengan asalan gelombang otak. Kawasan tersebut terdiri daripada a. hipotalamus b. talamus c. kawasan pangkal otak retikular klasik d. otak depan basal atau kawasan septum e. kawasan pineal-pituitari f. hipokampus g. amigdala h. kawasan limbik yang lain (forniks, habenular dan lain-lain) Apabila penelitian dibuat, selain daripada menjanakan gelombang otak, kawasan ini juga terlibat dengan pelbagai fungsi jasad dan mempunyai kaitan dengan koma serta ingatan. Oleh yang demikian, nampaknya, kawasan ini mempunyai sekurang-kurangnya satu ‘kawasan kecil’ (nod) yang membentuk pelbagai jaringan fungsi otak dan jasad. Oleh itu, kawasan ini dilihat sebagai kawasan yang teramat penting. Apabila ia tercedera, seseorang itu akan mengalami masalah hilang ingatan atau hilang kesedaran. Kedua-dua perkara ini adalah berkaitan dengan mengingat atau berzikir dan juga bersolat. Oleh itu, kawasan ini yang dikenali sebagai sistem limbik besar berkemungkinan besar ada kaitan dengan ‘pusat roh’ bagi jasad manusia. Perkara ini sudahpun dibahaskan semenjak dahulu lagi; Plato dan Leonardo da Vinci mengaitkannya dengan kawasan sistem limbik besar, manakala, Aristotle mengaitkannya dengan jantung. Istilah ‘pusat roh’ di sini dan seperti yang dibahaskan sebelum ini lebih merujuk kepada perkara yang berkaitan dengan ‘hidup dan mati’. Apabila kawasan sistem limbik besar diteliti, ia juga merangkumi: a. fungsi jasad (nod dalam jaringan otak) b. koma c. ingatan d. asalan gelombang otak yang berkait dengan minda [kaitannya mungkin seperti ini: jasad/otak-minda (gelombang otak)-qalbu/hati-roh atau jasad-minda-roh atau jasad-gelombang otak-roh; gelombang otak atau minda adalah manifestasi tidak langsung untuk roh] e. berada dalam posisi sujud atau mikrograviti f. anti-graviti (tiada masa dan dimensi, seperti elemen roh) g. pusat otak (kawasan intersepsi garisan-garisan infiniti) h. berkait dengan hidup dan mati Senarai di atas merangkumi secara am aspek roh atau pemetaan roh. Pemetaan fungsi otak pula boleh dibuat dengan menggunakan teknik-teknik seperti magnetoencephalography, electroencephalography, functional magnetic resonance imaging, transcranial magnetic stimulation, electrocorticography, diffusion tensor, dan pembedahan otak secara sedar dan stimulasi terus otak. Pemetaan otak ini membolehkan doktor atau pakar saraf mengenal pasti kawasan otak yang penting, contohnya seperti kawasan otak yang mengawal pergerakan, pertuturan, deria rasa, pendengaran, penglihatan dan fungsi kognitif seperti konsentrasi dan ingatan. Dengan yang demikian, pembedahan otak atau saraf dapat dilakukan dengan lebih selamat. Selain daripada itu, data-data yang diperolehi dapat digunakan untuk kajian yang lebih mendalam mengenai otak dan saraf, dan sebagai simpanan khas pemetaan otak manusia untuk sesebuah negara.

For the past decade, the rapid development of the ergonomics disciplines as well as the fast growing economy in the Asian region have been attracting the attention of the international ergonomics community. Although East Asia has been changing from a traditional agriculture-oriented society into a modern industry-oriented society and its economy covers a great deal of shared interests across the continents, yet the ergonomics related knowledge and practice are still in its infancy. Because of the geographic proximity and a strong historical, cultural and technology affinity, it is vitally important to maintain good communication and cooperation among the individuals as well as among the ergonomics organizations in the region. This symposium, EAEFS, has provided supporting ergonomics organizations and interested participants a forum to exchange ideas, build friendship, foster greater understanding of and among these individuals and organizations, and develop perspectives concerning ergonomics issues in this region and beyond. This volume contains the selected papers presented at the Second East Asian Ergonomics Federation Symposium (EAEFS), held from October 4 - 8, 2011 at the National Tsing Hua University in Taiwan. The Second EAEFS, endorsed by the International Ergonomics Association (IEA), aims to consolidate the established ties within East Asia and to extend the cooperation among ergonomics researchers, professionals, and practitioners in the region to other regions in Asia and the world. Senior scholars and leaders from Asian countries have shared their wisdom, experience, insights, and visions on past, current and future ergonomics efforts in Asia. The papers contributing to this book address the latest research and application in accordance with the theme of the symposium, "Ergonomics in Asia: Development, Opportunities and Challenges," and cover the following areas: Virtual Environments & Design, Aging & Work Ability, Usability & Interface, Biomechanics & Anthropometry, and Occupational Safety & Health.

Jointly hosted by the Ergonomics Society of South Africa (ESSA) and the International Ergonomics Association (IEA), this conference was attended by over 300 delegates and represented the largest and most prestigious gathering of eminent international ergonomists in the history of Africa. It also marked the beginning of a revival in concern for the well-being and productivity of people at work in South Africa.The conference aimed to juxtapose two great ergonomic themes – the under-developed ethos of the affluent societies and the technologically advanced ethos of the most affluent societies. The structure of the proceedings reflects this with the first section addressing the priorities of countries in transition and the last section addressing the priorities of the most industrially-developed countries, who have, by and large, long since solved the sorts of ergonomics problems currently of concern in the under-developed world. In between these, in a roughly hierarchical arrangement from micro- to macro- levels of analysis, are sections which collectively help span the whole field of ergonomics. Section overviews are provided to outline the topics included in each section.

This is an open access book. International Symposium – SEAVEG 2021 as a medium for educators, researchers, practitioners and students to convey the results of research, insights, knowledge, and innovations that have been carried out and compile them into a concrete, implementable formula. SEAVEG 2021 could be a discussion forum that encourages and accelerates agricultural development in Indonesia, especially horticultural commodities. The symposium welcomes papers that explore but not limited to the topic of Vegetables for Resilience and Healthy Diets. The range of the topics covered by SEAVEG 2021 includes: Hunger and MalnutritionStarvation occurs when a person does not get enough food, and in the long run, it can lead to malnutrition. Malnutrition can also occur when a person lacks essential nutrients as a result of not eating sufficiently.The horticultural sub-sector, especially vegetables, is a rich source of nutrients. As a food ingredient that contains many nutrients including vitamins and minerals, proper consumption of vegetables is important. It includes breeding, seed quality, production, and related aspects. Food and Nutrition Security Food as basic human need plays a significant role to create a good life. The availability of safe and nutritious food must be fulfilled. Food deficiency can create instability. >In order to achieve food stability, each country has different concepts and methods depending on their respective conditions, such as economic, geographic, technological, regional dan socio-cultural conditions. It includes breeding, seed quality, production, and related aspects. Food Supply Chain and Agribusiness In developing countries, the food supply chain has not been efficient because of the many actors involved. The supply chain describes the process of food, in this case from horticulture commodities, from production, processing, distribution, consumption, and disposal. Each step of the supply chain requires human resources that will reduce the farmer’s margin. The length of the supply chain also affects people’s purchasing power. Food Supply Chain is one of the many aspects from agribusiness system. To make an environmental that is leaning towards farmer’s prosperity, we need to make an agribusiness system that is efficient. Digital marketing system, such as marketplace, can shorten the supply chain and support better agribusiness system. Young Agripreneur in Horticulture Currently, young people around the world are not much interested in the agricultural sector. Agriculture, especially horticulture sub-sector, is very prospective to increase income and economic value. Farming vegetable commodity from upstream to downstream is very challenging for the millennial generation to develop. The demand in the horticultural sector, especially vegetable products, is increasing during the covid-19 pandemic. It is a business opportunity in itself, especially for young agricultural entrepreneurs. Millennial characteristics, adaptive to technology, full of innovation, make young agricultural entrepreneurs have the potential to increase the income and develop their business in horticultural commodities. Covid-19: Issues and Challenges in Vegetables for Resilience during PandemicThe Covid-19 pandemic is a momentum for the revival of the horticultural sub-sector. A balanced nutritional intake, especially vegetables, is highly recommended. People are increasingly aware that vegetables accompanied by a proper and healthy diet are beneficial for increasing body immunity. People are also encouraged to practice a healthier lifestyle to maintain endurance. Therefore, they will get infected by the disease. This change in mindset has influenced people’s interest in finding healthy food sources, such as vegetables that are good for health.
