식용 돼지췌장 리파제가 체다치즈에서 중성 휘발성 성분의 생산에 미치는 영향에 대하여 고찰하였다. 치즈 제조시 이 효소를 두 가지 함량으로 혼합하여 여러 온도에서 숙성시켰다. 2-butanone의 생산은 효소의 양과 숙성온도를 높였을 때 증가했으나, 2-pentanone의 생산은 숙성기간 중에 일관성이 없었다. Acetaldehyde는 aldehyde 중에서 가장 많이 생성되었고 일관성 있게 증가하였다. Alcohol 생산에서는 ethanol이 가장 높았지만 숙성 6주 후에는 일관성 있는 증가가 없었다. Ethylbutyrate는 ester중에서 가장 많이 생성되었고 리파제의 활성도와 숙성온도에 연관이 있었다. Dimethyl sulfide는 유일한 유황 성분이었지만 리파제의 첨가와 숙성온도에 영향이 없는 것으로 나타났다. 통계분석결과 치즈 숙성 중에 ethyl butyrate와 체다풍미가 유의성 있는 상호관계가 있었다.

식용 돼지췌장 리파제를 두 가지 함량으로 치즈제조시 혼합하여 $7^{\circ},\;13^{\circ},\;21^{\circ}C$에서 숙성시켰다. GC 분석결과 효소처리한 치즈에서는 Control에서 보다 훨씬 많은 양의 저급지방산이 생성되었다. 돼지췌장 리파제를 많이 넣어 $21^{\circ}C$에서 숙성시킨 치즈의 경우 1주 후에 medium flavor 치즈, 3주 후에 거의 sharp flavor 치즈가 특별한 결함없이 생산되었다. 또한 이 효소를 조금 넣은 치즈에서는 양호한 질의 치즈가 많았는데, $7^{\circ},\;13^{\circ},\;21^{\circ}C$에서 3주부터 15주의 숙성기간 중 medium과 sharp flavor 치즈가 생산되었다. 통계분석에 의하면 체다풍미와 caproic acid의 함량에서, 또 체다풍미와 butyric acid, caproic acid 혼합함량 상호관계에서 유의성이 있었다. 적합한 조건을 사용한다면 돼지췌장 리파제는 체다치즈의 숙성을 촉진시키는데 사용 가능한 것으로 사료된다.

The engineering knowledge and technology is core driving forces of continuous growth in knowledge based society. Companies, the government, and universities are the subjects of an innovation and the cooperation between them is very important. Nowadays, the main purpose of industry-university cooperation moves to train experts and develop a new product. A shift of the paradigm came from the change of recognition that the final consumers of the program are companies and the universities are supporters of the program. In this paper, we investigate the purpose, participation and satisfaction of companies to industry-academy technology cooperation through empirical studies. The need to expert training, product development and process development makes companies participate industry-academy technology cooperation and companies have different purpose of participation by the business type. Companies often feel that expert training, subsidiary purpose of industry-academy technology cooperation, is more important than product development or process development. This result is caused by the real world environment of small and mid-size companies, lacking of technology experts. The participation of companies to each technology cooperation program (technology transfer, joint technology development, consigned technology development, technology consulting, co-op. lab.) is also different by business type. The companies' satisfaction with the purpose of process development is relatively higher than that with the purpose of product development and companies show also different satisfaction value by business type and participating program. The results of this study can give a contribution to the design of demand oriented industry-academy technology cooperation model.

The continuous increase in the cost of energy production and concerns for environmental sustainability are leading research communities, governments and industries to amass efforts to reduce energy consumption and global $CO_2$ footprint. Players in the information and communication industry are keen on reducing the operational expenditures (OpEx) and maintaining the profitability of cellular networks. Meanwhile, network virtualization has been proposed in this regard as the main enabler for 5G mobile cellular networks. In this paper, we propose a generic framework of slice resource provisioning and customized physical resource allocation for energy-efficiency and quality of service optimization. In resource slicing, we consider user demand and population resources provisioning scheme aiming to satisfy quality of service (QoS). In customized physical resource allocation, we formulate this problem with an integer non-linear programming model, which is solved by a heuristic algorithm based on minimum vertex coverage. The proposed algorithm is compared with the existing approaches, without consideration of slice resource constraints via system-level simulations. From the perspective of infrastructure providers, traffic is scheduled over a limited number of active small-cell base stations (sc-BSs) that significantly reduce the system energy consumption and improve the system's spectral efficiency. From the perspective of virtual network operators and mobile users, the proposed approach can guarantee QoS for mobile users and improve user satisfaction.
