With the interest on operational efficiency due to the rapid growth of food material distribution industry and food service industry, the study adopts DEA (Data Envelopment Analysis) model and examines to measure the technological, pure technical and scale efficiency those companies engaging in the food material distribution and food service business. As a result of analysis, the companies operating integrated business have relatively higher efficiency than those operating only food material distribution or food service companies while the result indicates that three efficiencies don’t have significant difference depending on whether affiliated companies or not. In the results from the measuring by DEA.

Brands play a critical role as a core asset and the primary driver for corporate growth because of their power of identity and influence on customers’ perceptions in restaurant industry. However, in spite of diverse and dynamically changing recent brand portfolio strategies of restaurants, a study on the effect of brand diversification on financial performance has been rarely conducted in the restaurant industry context. Considering competing viewpoints regarding diversification’s influence on financial performance, the purpose of this study is, therefore, to examine the effect of brand diversification on firm performance of restaurants. The results indicated that brand diversification is positive effect to profitability. Brand diversification seems to be attractive and might be a reasonable growth strategy to expand market power by satisfying diverse consumer needs. Therefore, restaurant managers should be consider in implementing brand diversification strategy especially in dynamically changing trend of brand diversification in the current restaurant industry.

The purpose of this study is to identify a suitable organizational diagnostic model for analyzing the management efficiency of food service firms. We used the three-iteration Delphi technique on a panel of 19 business employees, 7 industry experts, and 4 employees in the food service industry. A total of 36 assessment indicators were developed through this panel, with numerous major findings. First, it is important to evaluate the leadership qualities of employees in terms of their motivation and competency. Second, it is important to evaluate the ability of employees to interface well with other employees. Third, it is important to evaluate and manage the brand image recognized by customers. Fourth, it is important to evaluate the fairness and regularity of the rewards given for an excellent job performance. Fifth, it is important to evaluate the level of communication and information distribution in the organizational culture. Last, but not least, it is important to evaluate the transparency and fairness of an organization in its human resource management (HRM) and the efficiency of its organizational structure. In conclusion, this study empirically shows how food service firms can develop an organizational diagnostic model to increase their managerial efficiency.

생쥐 초기배아의 체외배양 시 부화에 관련된 단백질 분해효소의 발현 시기와 존재부위를 알아보고 trypsin억제제 benzamidine을 배양액에 첨가하여 부화효소의 역할을 살펴보았다. 부화 효소로 제안되고 있는 trypsin 유사효소의 발현부위를 확인하기 위해 rhodamine이 부착되어 있는 Trypsin subsfrate probe를 이용하여 형광염색하였다. 생쥐 배아의 발생과정에서 trypsin 유사효소의 발현은 후기 상실 배아에서부터 관찰되었으며

컴퓨터 세포동결기를 이용하여 생쥐 배아를 동결할 때 액체질소 (L)의 분사속도가 해빙 후 배아의 미세구조, 기능 및 발달에 미치는 영향을 알아보고자 하였다. 이를 위해 배아는 동결을 하지 않은 대조군 (control) 및 동결군에서 L의 분사속도에 따라 고속분사군 (120 infusion/min group 1), 저속분사군 (50 infusion/min; group 2)으로 나누었다. ICR 계열의 생쥐의 2 세포기 배아를 사용하였으며, 동결 및 해빙은

초기배아의 발생과정동안 배아와 모체에서 발현되는 여러 cytokine은 착상을 위한 신호물질로 중요한 역할을 한다. 그 중 interleukin-1 (IL-1)는 배아와 모체간의 상호 신호전달체로서 성공적인 착상을 위한 필수적인 요소로 작용한다고 알려져 있다. 따라서 본 연구에서는 초기배아의 발생과정에 있어서 IL-1 유전자의 역할을 규명하기 위해 생쥐 초기배아에서의 IL-l 유전자의 발현양상을 역전사중합효소연쇄반응을 통해 조사하였고, IL-l 유전자의
