  • Previous performance evaluation focusing on objective data of service agency has the limitations that did not reflect user-centered evaluation. With the expansion of voucher service, importance of perspective of service user such as satisfaction index is increasing. As voucher service has been delivered by the financial burden of government and user, we need the performance evaluation system that reflects the both performance indices to meet the accountability of two stake-holders. So this study focuses on deriving integrated evaluation system developing systems what mixed objective and subjective performance. Data used in this study is collected form 70 social service agencies that deliver voucher service and 1445 service users. Using General Satisfaction Index and Efficiency Index by DEA, this study analysed the correlation between efficiency and satisfaction index, and integrated performance evaluation model is constructed through portfolio map. This study has the following implication. This study theoretically explains the relation of objective performance and subjective performance and gives practical guidance in performance evaluation criterion and interpretation of performance.

  • This experiment was conducted to investigate the variation of nitrogen use efficiency, nitrogen uptake efficiency, physiological utilization efficiency and their relationships with growth characteristics in the 28 Korean rice cultivars. Nitrogen use efficiency of 28 rice cultivars was 47.74, nitrogen uptake efficiency was 0.71, and physiological utilization efficiency was 68.76 in average. Nitrogen use efficiency of rice cultivars had low variation ranged from 44.09 to 51.91, but nitrogen uptake efficiency were relatively high variation from 0.51 to 0.90, and physiological utilization efficiency was from 51.71 to 94.26. The high efficient group in nitrogen uptake efficiency whose value was calculated above 0.80 included Daeanbyeo, Seojinbyeo, Ansungbyeo, Dongjinbyeo, and Hwaanbyeo, while the low efficient group with below 0.60 was Kwanganbyeo, Sampyeongbyeo, Soorabyeo, and Hwasungbyeo. Hwasungbyeo, Sampyeongbyeo, Soorabyeo for physiological utilization efficiency were more efficient cultivars, while Daeanbyeo, Seojinbyeo, Ansungbyeo were less efficient cultivars. Nitrogen uptake efficiency had positive correlation coefficients between dry matter weight of plant ($0.842^{**}$), leaf area index ($0.761^{**}$), and leaf nitrogen content ($0.599^{**}$), respectively. Therefore, the dry matter weight of rice plant and leaf area index was important characters to evaluate nitrogen uptake efficiency in rice cultivars. Also, more efficient cultivar in nitrogen uptake had higher chlorophyll meter value, which was appeared dark green color.

  • By far, numerous e-government projects requiring huge investments have been conducted in Korea to increase the administrative efficiency and improve the service quality via Internet. However, there's little research focusing on methods and techniques for analyzing and evaluating the projects either to economically justify the investments or to assess the quality of the system and of on-line services to citizens. The purpose of this paper is to suggest a set of factors to take into account for evaluating e-government portals and to empirically test the factors to provide useful implications for building such portals. Based on the literature reviewed, we constructed a research model that includes content, public service, community, design, technology, and portal's attributes as independent variables and the user's satisfaction and the administrative efficiency as dependent variables. A reliability test revealed that the evaluation factors proposed in the paper are sufficiently reliable, and a multi-regression analysis indicated that five hypotheses should be accepted. The findings of the study suggest that emphasis should be placed on public service quality and portal site attributes, among others, when implementing portals.

  • Recently, in the case that provides electronic services using Internet, we need the non-repudiation service that supplies a technological evidence about actions between a sender and a receiver that violate the promised protocol. Also, this service offers legal evidences while producing controversy. In this paper, we propose a protocol that improves the efficiency and offers the fairness of non-repudiation service by the extension of ability of TTP (Trusted Third Party). The proposed protocol adds a Time Check function and an Alert Message to extend the ability of TTP. Through the computer simulation, we prove that the proposed protocol has better efficiency than previous protocols.

  • BIM-based Cloud platform gained popularity coupled with the convergence of Fourth Industrial Revolution technology. However, most of the previous work has not guaranteed sufficient efficiency to meet user requirements according to BIM service. Furthermore, the Cloud environment is only used as a server and it does not consider cloud characteristics. For the processing of High Capacity Data like BIM and using seamless BIM service, Resource management technology is required in the cloud environment. In this paper, to solve the problems, we propose a BIM platform for BaaS and an efficient resource allocation scheme. We also proved the efficiency of resource for the proposed scheme by using existing schemes. By doing this, the proposed scheme looks forward to accelerating the growth of the BaaS through improving the user experience and resource efficiency.

  • The purpose of this study is to investigate the differences between the service providers and the users of 3PL services, in their perceptions about the qualities. The results of analysis identified five elements of the quality of 3PL services: reliability, efficiency, tangibility, responsiveness, and timeliness. The perceived importance and satisfaction showed the significant differences between 3PL service providers and the clients for all of the five elements. With respect to importance, efficiency showed the largest cognitive difference. Timeliness appeared to be the most important element perceived by both the service providers and the users. In terms of satisfaction, responsiveness indicated the biggest cognitive difference. In addition, it was noticed that the clients' satisfaction levels were particularly low, with respect to responsiveness and efficiency. It must be a strategic task of the 3PL service provider to improve customer satisfaction by reducing those cognitive differences.
