3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

of nanoparticles with tumor targeting molecules, such as hormones, growth factors etc. can increase the efficacy of a treatment. Integrin, EGFR are usually the target receptors.

of a Joint Expert Committee on Food Irradiation (JECFI) convened by the FAO, WHO, and the International Atomic Energy Agency (IAEA). The JECFI has evaluated available data in 1964, 1969, 1976, and 1980. In 1980, it concluded that the irradiation of any food commodity up to an overall average dose of 10 kGy presents no toxicological hazard and requires no further testing. It stated that irradiatio

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
Ⅰ. Introduction
The goal of Multivariate statistical analysis(MSA) is dimension reduction ofdata. Especially, visualization ofdata is very important. In various methods of MSA, Multidimensional scaling(MDS) is introduced and discussed as a graphical method to complement conventional descriptive and confirmatory methods in validation and analysis of QOL data. The use of MDS is illustrated i
