A hospital's intensive care unit (ICU) is a limited and critical resource whose efficient utilization of capacity impacts on both the welfare of patients and the hospital's cost effectiveness. Decisions made in the ICU affect the operations of other departments. Yet, decision making in an ICU tends to be mainly subjective and lacking in clear criteria upon which to base any given decision. The study reviews the capacity utilization of one particular ICU, that of a public hospital in Hong Kong, and develops a computer simulation model to improve both the unit's capacity utilization and the quality of care provided to its patients.

In this paper, we present the base station(BS) processing capacity to provide the multimedia services in IMT-2000 wireless communication network. The IMT-2000 services are classified into two types, circuit and packet services, and user‘s environments such as indoor, pedestrian and vehicle are considered. Using the parameters of service economics and wireless technology, the user's reference traffic and BS‘s traffic are computed. The traffic is measured by throughput(kbps). Based on the measured traffic, the accommodating users in BS are also evaluated. In addition to, the BS design capacity is presented for varying the number of users and traffic distribution in different user's environments.

In many make-to-order production systems customers ask due date confirmed and kept. Unexpected urgent orders from valuable customers often requires short lead times, which causes existing orders in the production schedule to be delayed so that their confirmed due dates cannot be met. This Imposes significant uncertainty on the production schedule in a supply chain. In this paper, we propose a new concept of capacity reservation as a viable tool for due date promising and suggest its operational alternatives. Simulation results show that the reserved capacity scheme appears to outperform simple FCFS scheduling policy in terms of the number of valuable urgent orders accepted and total profit attained.

This study empirically examines the proposition that the domestic fundamentals of a nation can emerge as absorptive capacity factors to reap the benefits of inward FDI. The study is contextualized in Asia, set from1982 to 2017, and data is grouped into low-income and lower-middle-income economies, in comparison to high-income and upper-middle-income economies, catering to different geographical regions within Asia. The investigation is based on a series of absorptive capacity factors such as infrastructure, human capital, domestic credit, and health indicator. The methodological analysis is premised on dynamic panel structure and employs the Generalized Method of Moments (GMM) estimation technique. The empirical findings suggest that that the infrastructure variable appears to be the major absorptive capacity factor for both groups of countries. The health indicator, on the other hand, can help reap the benefits of inward FDI, but only if the threshold level is met. The selected economies must achieve this threshold level to reap the benefits of FDI. To absorb the benefits of inward FDI, countries must be proactive in providing sound infrastructure and implementing proper healthcare measures.

This study was conducted to evaluate dietary supplementation of Sargassum horneri (SH) meal on growth performance, feed utilization, innate immunity, antioxidant capacity and disease resistance of Pacific white shrimp. The diets were added with graded levels of SH meal by 0, 0.5, 1, 2, 4 and 8% (designated as Con, SH0.5, SH1, SH2, SH4 and SH8, respectively). Quadruplicate groups of shrimp were hand-fed with one of the diets five times daily for 39 days. The innate immunity and antioxidant capacity of shrimp were significantly improved by the dietary SH supplementation. The cumulative survival of shrimp exposed to Vibrio parahaemolyticus in a challenge was higher in shrimp group fed SH diets, except for SH8, than that of shrimp fed the control diet. Growth performance and feed utilization of the shrimp were significantly decreased with the dietary SH inclusions except for 0.5%. Results indicated that dietary SH meal could be used as a functional supplement for improvements in innate immunity, antioxidant capacity and disease resistance in Pacific white shrimp. The suggested dietary inclusion level of dried SH is approximately 0.5% for the shrimp.

Most small and petty marine engine mechanical shops are jumbled up and their facilities are falling behind, and is varying. By theses reasons, it's capacity becomes weak and also by the insufficience of the promotion policy, it is hard to be expected to improve their business. The feature, management, manpower, facilities for the marine engine mechanical shops were researched and their problems were analyzed. In this study, the way to strengthen their capacity and to manage the shops efficiently was researched.
