To examine the opinions of consumers concerning the ricecake as a traditional food, we conducted the study of the cognition and interests of children and mothers ricecake for its popularization. Our subjects of study were elementary school children as the future consumers and their mothers as the present consumers. The results were as follows: children favored to eat much more western style food and sweet food than did mothers. All of children and mothers liked traditional food and ricecake, but children did not know how to prepare the traditional food and ricecake, indicating thenecessity of the education of ricecake-making. All of them were satisfied with the taste of ricecake 'on sale, but not with packaging designs and price of ricecake. Development of packaging designs was required for popularization of ricecake to spread worldwide.

Ethnic Korean onggi earthenwares were fabricated using different clay formulations and glazing treatments. Their permeability properties against oxygen, carbon dioxide, and moisture were measured at $20^{\circ}C$ and examined from the aspect of food preservation. Onggi walls consisted of micropores that offered higher gas and moisture permeation rates when compared with other food packaging materials. Earthenware walls were unique in having $CO_2/O_2$ permeability ratios of 0.60-1.00. Gas and moisture permeabilities were lower, with wall structure having lower porosity and surface glazing. Results revealed onggi jar packages of grape fruits could attain wide range of $O_2$ and $CO_2$ concentrations. Onggi containers present good opportunity to obtain optimum packaging conditions for respiring or ripening products, depending on commodity type.

The need to determine the permeability of organic vapors to polymeric films such as aromas, flavors, etc. has significantly increased in the food industry because of preservation and safety issues along with migration problems. However, due to the complex nature of the permeation process, there have been few investigations compared to nonorganic compounds. In this paper, we review the history of permeability studies and typical methods of permeability measurement such as the isostatic method and quasi-isostatic method for organic vapors. New instrumental developments and significant findings are also introduced and discussed.
