  • The texture describing terms used for the Korean staple foods, cooked rice, noodles and Kimchi, were surveryed by questionnaire. A total of 154 kinds of terms were collected from 68 answers, in which 95 words were found with definite textural meaning in Korean dictionaries. The terms were classified according to their physical properties by Szczesniak's method. The important textural properties of different types of Korean foods were pointed out by the frequency of mentioning and by the preference expressions. The representative Korean words expressing each textural property of different types of food were selected. The important textural properties for Korean were hardness, brittle-gumminess, chewiness, springiness, adhesiveness, particle size and shape, moisture content and fat content of cooked rice, chewiness, hardness, springiness, and particle size and shape of noodles, and hardness, brittle-gumminess, chewiness, springiness and particle shape and orientation of Kimchi.

  • Recent trial results suggest that the consumption of a low glycemic index (GI) diet is beneficial in the prevention of high blood glucose levels. Identifying active hypoglycemic substances in ordinary foods could be a significant benefit to the management of blood glucose. It has been hypothesized that noodles with Bombyx mori powder are a low GI food. We evaluated GI and changes in postprandial glucose levels following consumption of those noodles and compared them with those following consumption of plain wheat flour noodles (control) and glucose (reference) in healthy subjects. Thirteen males (age: $34.2{\pm}4.5years$, body mass index: $23.2{\pm}1.1kg/m^2$) consumed 75 g carbohydrate portions of glucose and the 2 kinds of noodle after an overnight fast. Capillary blood was measured at time 0 (fasting), 15, 30, 45, 60, 90, 120, and 180 min from the start of each food intake. The GI values were calculated by taking the ratio of the incremental area under the blood glucose response curve (IAUC) for the noodles and glucose. There was a significant difference in postprandial glucose concentrations at 30 and 45 min between the control noodles and the noodles with Bombyx mori powder: the IAUC and GI for the noodles with Bombyx mori powder were significantly lower than those for glucose and plain wheat flour noodles. The wheat flour noodles with Bombyx mori powder could help prevent an increase in postprandial glucose response and possibly provide an alternative to other carbohydrate staple foods for glycemic management.

  • The Gwugonsiuebang is a book of Korean woman's life in the Yi dynasty which published I 1653 by Mme. Jang. I have studied the food habits of the Yi dynasty that wrote in Gwugonsiueband as following. The staple foods are Guksu (wheat vemicell as like western noodles) 5, Mandu (bun stuffed with seasoned meat and vegetables) 6 kinds in this book. the side dishes are Guk (soup) 8, J'm (steamed meat or fish) 6, chae6, Nooruemi 5, Hyae (sliced raw fish) 3, Jockpyun (jellied beef soup) 3, Jockgall (salted sea food) 2, Jock (skewer or broach) 2, jihee 2, Sun (Steaming of stuffed vegetable) 1, Bockuem (saute) 1, Jon (pan fried fish) 1, Gui (meat or fish grilled with seasoning) 1, and the other 13 kinds. The desserts are D,ock (Korean rice cake) 11, jabgwa 8, Beverages 5 kinds and Jungwa 1 kind. The alcohol and fruits wine are 51 kinds. The alcohol and fruits wine are 51 kinds. The seasonings are Soybean sauce, oil, Sesamol oil, pepper, Ginger, Garlic, Vinegar, Wine, Salt, Bean paste etc. Raw materials of Guksu, Mandu, D'ock, Jabgwa, Beverage, Wine, vinegar are all carbohydrates. It shows that a tendency of Korean people too much take a carbohydrates. Now and then, there are no special difference of winter over pass for vegetables, fruits, dried beef, dried fish and salt fishes. In yi dynasty, there are 62 kinds of table ware and cooking kitchen utensils, but many of them come to uselessness. 19 kinds of measuring unit are very non-scientific because that is not by weight but by bulk or volume. There are many food making terms which are 198 kinds of prepared cooking term, 11 kinds of cutting term and 20 kinds of boiling term. And 10 kinds of expression of taste can see this book.

  • Growing of number of elderly populations, which may be caused by improved quality of life and decreased the percentage of mortality. Although there is a declining rate of the edentulous patients, more patients are advancing into older age groups, and the substantial number of edentulous patients are increasing. For these edentulous patients, complete denture cannot substitute natural teeth, but it is a staple prosthetic treatment. Generally, the success of dentures has been evaluated on the basis of whether or not patients comfortable and were able to masticate with their dentures. Acceptance of complete denture is complex for patients and related to psychological factors of patients, physical state, and the technical quality of dentures. In addition to that, many factors influence to satisfaction of patients to the complete dentures. In this review article, evaluate various factors related on satisfaction of denture wearers and methods of evaluate satisfaction.

  • Eunsa Memorial Science Museum is a political space to justify ruling colony. Japanese imperialism made use of science museum in ruling colony under the cloak of propagating science thoughts. The science museums made it natural to rule the inferior Joseon(Korea) by bring the concept of 'Great Science Empire' into relief. The exhibition, lecture, experiment and science movies propagated those colonial ruling ideology. This transplantation of the colonial science museumraised the following problems. First, the science museum was used as means for the propagation of political power. All the aspects of the architecture, exhibition, and operation of the colonial science museum propagated and supported the direction of political authority, and furthermore planted a rosy phantasm of 'Development' and 'Progression' into the colony. Second, The science technology of science museum was treated as 'Result' and 'Instrument'. Japanese imperialism denied that the science is a historical and cultural staple product; it instilled only the 'Instrumental Rationality' in the colony. Third, the science technology dealt in the colonial science museum was below the level. What they educated and set forth as domestic science was to cultivate the laborers people for the political power by internalizing modernistic discipline.

  • There has been an impetus in the development of biocontrol agents (BCAs) with the removal of a number of chemical compounds in the market, especially in the European Union. This has been a major driver in the development of Integrated Pest Management systems (IPM) for both pest and disease control. For control of mycotoxigenic fungi, there is interest in both control of colonization and more importantly toxin contamination of staple food commodities. Thus the relative inoculum potential of biocontrol agent vs the toxigenic specie sis important. The major bottlenecks in the production and development of formulations of biocontrol agents are the resilience of the strains, inoculum quality and formulation with effective field efficacy. It was recently been shown for mycotoxigenic fungi such as Aspergillus flavus, under extreme climate change conditions, growth is not affected although there may be a stimulation of aflatoxin production. Thus, the development of resilient biocontrol strains which can may have conserved control efficacy but have the necessary resilience becomes critical form a food security point of view. Indeed, under predicted climate change scenarios the diversity of pests and fungal diseases are expected to have profound impacts on food security. Thus, when examining the identification of potential biocontrol strains, production and formulation it is critical that the resilience to CC environmental factors are included and quantified. The problems in relation to the physiological competence and the relative humidity range over which efficacy can occur, especially pre-harvest may be increase under climate change conditions. We have examined the efficacy of atoxigenic strains of A. flavus and Clanostachys rosea and other candidates for control of A. flavus and aflatoxin contamination of maize, and for Fusarium verticillioides and fumonisin toxin control. We have also examined the potential use of fluidized-bed drying, nanoparticles/nanospheres and encapsulation approaches to enhance the potential for the production of resilient biocontrol formulations. The objective being the delivery of biocontrol efficacy under extreme interacting climatic conditions. The potential impact of climate change factors on the efficacy of biocontrol of fungal diseases and mycotoxins are discussed.

  • Brown rice (Oryza sativa) is rich in nutrients, including dietary fiber, vitamins, minerals, and other unmeasured constituents, as well as carbohydrates. Brown rice is an applicable staple for chronic diseases, such as diabetes and hyperlipidemia, but it is not commonly used in dietary management due to several reasons. In this study, we investigated the possibility of using digestive enzymes to process brown rice. When the weight of the brown rice was measured after packing in the same volume of water, it was increased in pectinase-treated brown rice compared to control or collagenase-treated brown rice. Using SEM analysis, we observed huge scratches and nanopores on the surface of the brown rice after the pectinase treatment, but the nutritional components were preserved. We also analyzed the water adsorption rate and performed a starch reaction assay to examine the physical changes after the pectinase treatment. The pectinase-treated brown rice showed a higher water adsorption rate and a faster starch reaction than the nontreated brown rice. These results suggest that digestive enzymes like pectinase can aid the nutritional preservation of brown rice and improve its taste.

  • Vegetation canopy plays an important role in $CO_2$/$H_2$O exchange between the biosphere and the atmosphere by controlling leaf stomata. In this study, rice (Oryza sativa L.), a staple crop in Asia was investigated to formulate its single leaf model of photosynthesis and stomatal conductance. Photosynthesis and stomatal conductance were measured with a portable infrared gas analyzer system. Other plant and meteorological variables were also measured. To evaluate empirical constants in this biochemical leaf model, nonlinear least squares technique was used. The maximum catalytic activity of enzyme and the maximum rate of electron transport were $ 100\mu$$m^{-2}$ $s^{-1}$ and $140 \mu$㏖ m$^{-2}$ s$^{-1}$ (@ 35$^{\circ}C$), respectively. The empirical constants, m and b, associated with stomatal conductance model were 9.7 and $0.06 m^{-2}$ $s^{-1}$ , respectively. On a leaf scale, agreements between the modeled and the measured values of photosynthesis and stomatal conductance were on average within 20%, and the simulation of diurnal variation was also satisfactory On a canopy scale, the Simple Biosphere model(SiB2) was tested using the derived parameters. The modeled energy fluxes were compared against the micrometeorologically measured fluxes over a rice canopy. Agreements between the modeled and the measured values of net radiation, sensible heat and latent heat fluxes, and $CO_2$ flux (i.e., net canopy photosynthesis) were on average within 25%.

  • Soybean, rice and nuts are the staple foods in South East Asia. In order to clarify the function of these foods in relation to coronary heart diseases, we have done a series of experiments using animals and humans. Soybean protein preparations (SPI) in comparison with an animal protein, casein (CAS), resulted in reducing atherosclerotic lesion development in apolipoprotein (apo) E deficient mice that develop an advanced lesion similar to that in humans. This action was attributed to the protein, since the ethanol-extracted SPI (EE-SPI), from which isoflavones and saponins removed, lowered the lesion development in apo E-deficient mice. However, The EE-SPI, compared to the SPI, resulted in a decrease of mRNA for key proteins of cholesterol metabolism (low density lipoprotein receptor and cholesterol 7$\alpha$-hydroxylase) in hypercholesterolemic rats, followed by an elevation of the serum cholesterol level, indicating a contribution of isoflavones to the serum cholesterol level. Rice protein (RPI) was also effective to lower the lesion development in apo E deficient mice. Both the SPI and RPI led to an increased level of the serum NOiN03, metabolites of NO. This effect appeared to be attributed to their high content of arginine. Besides, C57BL/6J mice fed a diet containing whole grain rice had an elevation of the serum high-density lipoprotein cholesterol. Furthermore, rice bran oil and the unsaponifiable fraction that is rich in plant sterols were effective to lower serum cholesterol levels in hypercholeserolemic rats. Finally, we tested if walnuts consumption would be hypocholesterolemic for Japanese. A diet containing walnuts effectively lowered the serum total and low density lipoprotein cholesterol in Japanese men and women. These animal and human experiments would be relevant to advocate publics to keep consuming diets including soybean, rice and nuts for their healthful life.
