The purpose of this study is to predict the economic size of foods-for-elderly market, which will be valuable information for establishing related policy and backup system. After setting the scope of related industry, detailed information for current market situation was investigated and a systematic forecast for market changes in the future was performed. Economic growth, changes in consumer expenditure and economic status of the elderly, current subscription of medical insurance and saving for pension were reflected. In addition, a survey toward related firms was completed and changes in aged population and incidence of chronic disease in the elderly were taken into account. Results show that the annual growth rate of the market was predicted to be the minimum 4.54% through the maximum 8.32% from 2010 to 2025 and its market size was forecasted to be the minimum 7,073 ten million won through the maximum 10,976 ten million won. It is expected that the market of foods-for-elderly will grow rapidly with development of foods technology and fast increase of aged population. Especially, growth of health functional foods and foods for special dietary uses for elderly will be distinguished. However, it seems that related firms are on the hedge, watching current trend of the related industry. This may results in insufficient supply against the demand. Therefore, policy for foods-for-elderly should be introduced and systematically administered, including R&D support, standardization and authentication for foods-for-elderly, construction of related database system.

${\bigcirc}$ SWOT 분석 내용을 토대로 신바이오틱스를 활용한 노년층 맞춤형 건강기능식품 시장 진입에 있어 고려 사항에 대하여 다음과 같이 제언함. ${\bigcirc}$ (노년층 맞춤형 건강기능식품에 대한 차별성 강조) 기존 시중에 판매되고 있는 건강기능식품의 경우 특정 연령층을 대상으로 한 제품이 아닌 전 연령층을 대상으로 한 기능성을 강조한 제품으로 각 업체별 시장 진입시 '노년층 맞춤형 건강기능식품'이라는 점을 부각, 차별성 확보 방안이 필요함. ${\bigcirc}$ (신바이오틱스의 기능성 홍보 방안 마련) 상기한 바와 같이 현재 홍삼 및 비타민 중심의 시장이 형성되어 있어 프로바이오틱스를 포함한 신바이오틱스에 대한 인지가 낮은 상황으로 이를 해소할 수 있도록 신바이오틱스 기능성을 강조한 홍보 방안 마련이 필요함. ${\bigcirc}$ (환자식 제품시장 진입 고려) 현재 국내 노년층 건강식품시장은 아직 규모 및 활성화가 미비한 도입기에 시장으로 판단되는 만큼, 노인 건강기능식품 시장에 우선 진입함으로써 가질수 있는 선발자 우위 확보 전략 또는 신비아오틱스 활용이 가능한 관련 시장 중 환자식(특수의료용도식품)제품 시장에 제품차별화를 통해 기존 시장에 진입하는 전략 등에 대한 고려가 필요.

Produced by steaming mature silkworms, HongJam is a natural functional food with various health-promoting effects. The current standard HongJam production protocol involves freezing and freeze-drying steamed mature silkworms for convenient long-term storage and/or selling it to customers. However, freeze-drying HongJam requires a range of processes and costs, which have contributed to its high resale value. In this study, we found that the cost of manufacturing HongJam powder could be reduced by homogenizing steamed mature silkworms using a high-speed blender and digital homogenizer, followed by spray drying. After the homogenized HongJam solution was digested by directly adding food-graded proteases, food-graded protease-digested homogenized HongJam solution was spray-dried. Food-graded digested protease or non-digested homogenized HongJam solutions could be used to produce food for special medical use for patients with general or specific diseases. This more efficient HongJam processing protocol proposed in this study can facilitate the development of sericulture farms and related industries by reducing the production costs of HongJam and its associated products.

최근들어 미생물 이용에 관한 연구가 활잘해지면서 많은 진보가 있었다. 미생물반응을 촉매하는 효소는 각종 공업생산물, 식품공업및 의료에 응용되고 있는데 특히 특이성이 높기 때문에 특수성분의 생산, 계측및 성분의 분석수단에 다방면으로 이용되고 있다. 그러나 이용분야가 넓고 다양한 점에 비하여 현재까지 공업적으로 사용되고 있는 효소의 종류는 그리 많지 않다. 더구나 미생물이 생산하는 효소는 생산성및 안정성 때문에 이용이 제한되어 있으며 현재에는 20여종에 불과하다. 지금까지 산업적으로 이용되지 않고 있는 효소는 1) 효소를 생산하는 미생물의 안정성 문제 2) 미생물효소의 생산성이 낮거나 3) 효소의 특성이 구명되지 않아 용도의 개발이 늦어지고 있기 때문이다. 따라서 유전자 조작을 통한 생산성및 안정성 문제의 해겨, Bioreactor 기술 개발로 생산성의 증대등으로 효소의 산업적 응용을 가능하게 하리라 본다. 한편으로는 효소를 분리하여 여러가지 특성을 구명한다면 새로운 효소를 발견하고 또한 새로운 용도를 개발할 수 있을 것이다.

Corrosion is the degradation of metals by reaction with the environment. It is difficult to completely remove. Corrosion proceeds rapidly after the protective barrier is destroyed, and several reactions occur that alter the composition and properties of the metal surface and local environments, such as diffusion of metal cations into the matrix, the formation of oxides, and local pH changes. The study of corrosion of steel and iron is of theoretical and practical interest and is receiving considerable attention. Acid solutions, which are widely used in industrial pickling, acid descaling, cleaning and acidification of oil wells, require the use of corrosion inhibitors to suppress corrosion attacks on metallic materials. Physical removal of rust requires expensive special equipment, and chemical removal of it can cause corrosion or shorten the life of the metal. In this study, an eco-friendly rust cleaner was developed using cosmetics and food materials by applying the concept of perm reducing agent and chelate, and applied to remove rust from industrial and hot water pipes and various industrial devices. As a result, it was found that rust cleaners remove rust more effectively and safely compared to conventional treatment methods. At the same time, the rust removal efficiency was 1.75 to 2.5 times better for industrial piping and 1.56 to 2.2 times better for boiler hot water than conventional methods.
