Recently, as a study to air cooled slag, which is an industrial by-product, research is being proceed to use it as a material for concrete. In this study, the workability, air content, compressive strength, CO₂ emission and economic feasibility of concrete were analyzed when air cooled slag, an industrial by-product, was applied as aggregate for rural road pavement concrete. As a result of the analysis, both the slump and air contents test results of concrete using the air cooled slag aggregate satisfied the target values, and the compressive strength was increased when the air cooled slag aggregate was used compared to when the natural aggregate was applied. On the other hand, the largest amount of CO₂ emission by raw material was found in aggregate. The carbon emission of rural road pavement concrete using air cooled slag aggregate increased when the Korean LCI DB was applied compared to when natural and crushed aggregates were applied, and the emission decreased when the German LCI DB was applied. This results are due to differences in the viewpoints of industrial by-products. However, considering the recycling of waste from the environmental aspect, it is necessary to simultaneously review the CO₂ emission and recycling aspects in the future. Also, the application of air cooled slag aggregate had the effect of improving the economic efficiency of rural road pavement concrete about 18.75%.

Packages of different atmospheres (air (control), 100% CO₂, vacuum, and vacuum + O₂ absorber) were prepared for 0.4 kg rice cake (ddukgukdduk) using gas-barrier plastic film and stored at 10℃ for 11 days. The stored products were evaluated in their packages atmosphere, total aerobic bacteria, yeast and molds, texture and sensory quality during storage period. In the air package, the O₂ concentration decreased from initial 21% to 16% on storage 4 days and the CO₂ concentration increased to 23% on storage of 11 days, which resulted from the growth of microorganisms. CO₂ concentration decreased from initial 98% to 36% on storage 11 days in the 100% CO₂ package. It is reasoned that CO₂ was dissolved into the product reducing the volume of the package. Vacuum and vacuum +O₂ absorber package maintained shrunk vacuum condition until 11 days of storage. Total aerobic bacteria count increased significantly in the control package (6.41 log (cfu/g) after 11 days) compared to the 100% CO₂ package (4.96 log (cfu/g) after 11 days). Yeast and molds were 6.66 in control package, 3.43 in 100% CO₂ package, 4.66 in vacuum package, and 3.78 in vacuum + O₂ absorber package after 11 days. There was no significant difference between control and the other treatments for the texture of the stored products. Sensory quality was the worst in control package on the storage of 8 days. All treatment groups except control improved the quality preservation, but vacuum and vacuum + O₂ absorber packages suffered from cracking of the product. Thus 100% CO₂ flushing is suggested as a desired packaging condition.

산업의 융합화 추세는 IT서비스 산업이 복잡한 서비스 시스템 통합과 더불어, 제품과 서비스의 융/복합화를 위한 PSS(Product Service System) 구현에 많은 노력을 요구하는 동인으로 작용하고 있다. 이는 제품의 서비스화(product servicize)와 서비스의 제품화(service productize) 현상의 가속화로 인해 제품과 서비스의 구분이 모호해지고 있는 산업변화에 대응하려는 산업의 노력으로 판단된다. 고객 가치 향상을 위해 IT서비스 제조산업(IT Service manufacturing)에서는 제품과 서비스의 모호한 경계를 극복하고, 서비스중심의 신규 IT서비스를 개발할 수 있는 무형의 프로세스 정립이 요구된다. 본 연구에서는 서비스 사이언스 측면에서 제공되는 기법들(PSS, NPD, NSD, UCD, Contingency theory)을 검토하여, IT서비스 제조산업의 특성이 반영된 마케팅 지원 process tool을 개발하는 데에 목적이 있다. 제안된 tool은 목표시장 및 기술환경의 분석과 동시에 IT서비스 제품 분석을 통해 IT서비스 사업 마케팅 기회를 전략적으로 탐색할 수 있는 도구가 될 수 있을 것으로 판단된다.
