The demand for beef as a protein source is increasing worldwide, although in most countries beef accounts for considerably less than half of total meat consumption. Beef also provides a highly desirable eating experience in developed countries and, increasingly, in developing countries. The sustainability of beef production has different meanings in the various geographical and socio-economic regions of the world. Natural resources including land mass and uses, rainfall and access to livestock feed, and the robustness of the economy are major determinants of the perception of beef sustainability. In this overview of the 2016 International Symposium on "Future Beef in Asia" and this subsequent Special Edition of the Asian-Australasian Journal of Animal Sciences on "Current Situation and Future Prospects for Global Beef Production", the contributions have been grouped into the following categories: Countries in Southeast Asia; Europe; and Countries producing highly marbled beef for export and/or domestic consumption. They also include reference to Special Topics including marbled beef production, and use of "omics" technologies to enhance beef quality assurance. Among these broad categories, notable differences exist across countries in the production and marketing of beef. These reflect differences in factors including natural resource availability and climate, population size, traditional culture and degree of economic development including industrial and technological developments. We trust that the International Symposium and this Special Edition on Current Situation and Future Prospects for Global Beef Production, the contents of which that are briefly summarized in this paper, will serve as a valuable resource for the livestock industries, researchers and students with an interest in enhancing the prospects for sustainable, efficient beef production that satisfies the growing size and complexity of consumer demands and markets for beef.

Traditional drugs(herbal and animal drugs) of Korea, China and Japan have developed essentially from the same origin, since the traditional medicine of three countries has been originated from ancient China. Due to different geographical locations and discrepancy of plant resources of the traditional drugs, some divergency in terms of systematic botany in traditional drug materials has appeared in the three countries. Present report aims to survey traditional herbal drugs that have been called same traditional names in three countries, but they are actually different with respect to systematic botanical view-point. The official drug compendia(pharmacopoeia and natural drug standards) of three countries were subject to examination. Survey was conducted by the following categories. Traditional drugs were listed under same name, however, 1) they belong to different genus; 7 traditional herbal drugs were listed. 2) they belong to same genus, but different species; 24 traditional herbal drugs were found. 3) a variety of related species are used; 15 traditional drugs were listed. 4) actually same plant, but taxonomical name is differently called and/or different parts of plant are used; 10 traditional drugs were counted. 5) animal drugs belong to one of the above categories; 7 traditional animal drugs were found. Total 63 traditional drugs(herbal and animal) were found to comprise different taxonomical names when the official drug compendia of Korea, China and Japan were examined.

Cryo-electron microscopy (cryo-EM) is arguably the most powerful tool used in structural biology. It is an important analytical technique that is used for gaining insight into the functional and molecular mechanisms of biomolecules involved in several physiological processes. Cryo-EM can be separated into the following three groups according to the analytical purposes and the features of the biological samples: cryo-electron tomography (cryo-ET), cryo-single-particle reconstruction, and cryo-electron crystallography. Cryo-tomography is a unique EM technique that is used to study intact biomolecular complexes within their original environments; it can provide mechanistic insights that are challenging for other EM-methods. However, the resolution of reconstructed three-dimensional (3D) models generated by cryo-ET is relatively low, while single-particle reconstruction can reproduce biomolecular structures having near-atomic resolution without the need for crystallization unless the samples are large (>200 kDa) and highly symmetrical. Cryo-electron crystallography is subdivided into the following two categories according to the types of samples: one category that deals with two-dimensional (2D) crystalline arrays and the other category that uses 3D crystals. These two categories of electron-crystallographic techniques use different diffraction data obtained from still diffraction and continuous-rotation diffraction. In this paper, we review crystal-based cryo-EM techniques and focus on the recently developed 3D electron-crystallographic technique called microcrystal-electron diffraction.
