Salted anchovy, generally favored in Europe, is one of the traditional fermented fish products in southern European countries and raw anchovy are aged in 20∼30％ NaCl solution for 6 months (Ishida et al., 1994). They are then steeped in oil in glass jar or can, and marketed. The salt-fermented fish sauce, such as anchovy sauce and shrimp sauce are tropical fermented seafood from fish in Korea. (omitted)

Norovirus (NV) is becoming a major cause of foodborne illness in many countries. At present, very little is known about the survival of NV in the environment or the disinfection procedures needed to remove NV from contaminated surfaces. Feline calicivirus (FCV, $1{\times}10^{6.75}\;TCID_{50}/mL$) was used as a surrogate model for NV to investigate the effectiveness of sanitizing treatments for the viruses attached to food and food contact surfaces. Ammonium chloride (2%), organic acids (3000 ppm), and ethanol (70%) were most effective, providing $4\;log_{10}$ (99.99%) reductions in FCV titers on food or food contact surfaces. The disinfection efficacies of most agents on ceramic and glass surfaces were greater than stainless steel. The results from this study can be applied in the food industry to reduce NV-associated foodborne illnesses.

For the development of a ultra-precision CNC polishing system including on-machine measurement system, we study a corrective polishing algorithm. We calculated unit removal profiles for various flat type polishing tools and polishing tool positions. Using these results we simulate the corrective polishing process based on dwell time control. We calculate dwell time distributions and residual error of the polishing simulation method and the FFT calculation method. We test corrective polishing algorithm with an optical glass. The target removal shape is a sine wave that has amplitude 0.3 micro meters. We find this polishing process has a machining resolution of nanometer order and is effective for sub-micrometer order machining. This result will be used for the software development of the CNC polishing system.

Bauhaus, founded in Weimar, Germany in 1919, represented Modernism which is proven in the field of art as well as architecture. Furthermore, in design field, Bauhaus is the essential historical event whose influence continues in contemporary design. Bauhaus furniture is simple and austere and has linear shapes which are suitable for mass production. Bauhaus developed functional furniture design such as knock-down and pre-fabricated furniture. In terms of finishes, Bauhaus furniture epitomizes the influence of De Stijl which used either achromatic colors and three primary colors or natural finishes of wood. Bauhaus contributed to furniture design field as below. 1. Success in mass-produced furniture through standardization and pre-fabrication 2. Pioneered on industrialization through collaboration between academia and industry 3. played essential role developing modem furniture by using not only metal but also such diverse materials as plywood, glass, and leather

In recent years there have been considerable attentions on nanoimprint lithography (NIL) by the display device and semiconductor industry due to its potential abilities that enable cost-effective and high-throughput nanofabrication. A major disadvantage of thermal NIL is the thermal cycle, that is, heating over glass transition temperature and then cooling below it, which requires a significant amount of processing time and limits the throughput. One of the methods to overcome this disadvantage is to improve the cooling performance in NIL process. In this paper, a numerical analysis model of cooling system in thermal NIL was development by CAD/CAE program and the performance of the cooling system was analyzed by the model. The calculated temperatures of nanoimprint device were verified by the measurements. By using the analysis model, the case that the cooling material is replaced by liquid nitrogen is investigated.

The first membrane technology applied in the Japanese industry was a. electro-dialysis(ED) process using ion-exchange meabranes. These membranes were first developed in early 50ties and the Japanese government decided to use this method for concentration of sea water to produce salt, which was then produced by solar evaporation. This development program started from 1960 by the Japan monopoly Coop. (at that time). To apply ED process for sea-water concentrat ion it was necessary to develop ion-exchange membranes having very low electric resistance to avoid energy loss due to Joule heat, and those having selectivity to permeate single valent ions only to avoid scale formation in the ED stacks. These Japanese companies, Asahi Glass, Asahi Chemical and Tokuyama Soda, have succeeded to develop such membranes, and until 1971 all of the seven salt manufacturing companies had adopted ED for production of food salt.

In the current study, factors affecting cheese brands products in grocery stores were evaluated with an emphasis on diversity. The sample data were collected from Noushad and Pegah Milk Industry in 2015 and data were extracted, reviewed, and analyzed from 435 grocery stores in Mashhad using seemingly unrelated regression model and particle swarm optimization algorithm. Results showed that optimum amount of Kalleh product diversity is higher than other competitors in the market, and Kalleh UF diversity is 100 to 250 grams, and Kalleh UF diversity with weight of 300 to 500 grams is more than other modes of diversity, and Kalleh brand must remove tin cheese from the market. Sabah Brand also should eliminate its glass and creamy diversity from market, UF diversity is mostly welcomed in market.

Lowering the dielectric constant is one of the important issues for the efficiency and the power consumption in the plasma display panel (PDP) industry. This study examined the effect of the addition of ceramic filler (up to 10% of crystalline and amorphous silica, respectively) to a $B_2O_3$-ZnO- $P_2O_5$ glass matrix on the dielectric, coefficient of thermal expansion, etching behaviors and residual stress for the barrier ribs in plasma display panels. The dielectric constant of barrier ribs is affected by containing two types of $SiO_2$ filler for the barrier rib composition in PDP.

Recently western countries are now beginning to use ACM (Advanced Composite Material) in the construction industry. Compared with conventional construction materials, ACM possesses many advantages such as light-weight, high-strength, corrosion resistant properties, etc. Among other fabrication process of ACM, pultrusion is one of the promising one for civil infrastructure application. In this paper, the structural characteristics of pultruded glass fiber reinforced composite structural member of angle and tube type were studied. Experiments for compression were performed for those members along with finite element buckling analysis with ABAQUS. The experimental and analytic results were compared each other and they were also compared with predicted values using coded formulae.

Ag conductive thick film has been used in bus and address electrodes of PDP (Plasma display panel). In PDP fabrication, the firing temperature of electrode is normally $550{\sim}580^{\circ}C$. For the application of PDP industry, we investigated an Ag conductive thick film with firing temperature. Low melting glass frit was used in the conductive thick film. The thermal properties of Ag and frit were determined by a hot stage microscopy. Based on the our results, we suggest that the Ag conductive thick film should be considered of the firing temperature which is correlated to the shrinkage, conductivity, and shape of thick film.
