advancement of computer technologies enables us to answer to " How to " questions as well. An efficient " Simulation Gptimization " technique is developed to solve system design problems which can not be expressed in explicit analytical or mathematical models. In particular, we explore a new paradigm called the " Reverse-Simulation optimization method'(More)
BACKGROUND/AIMS The purpose of this study was to evaluate the clinicopathologic characteristics of colon cancers detected at the SOK Sokpeynhan Internal Medical Network, a nationwide system of primary health care institutions. METHODS We analyzed 579 colon cancer patients diagnosed using colonoscopy at the SOK network from January 2011 through December(More)
Though it is an era of technological advancement and autonomy, due to increase in population and the use of electrical equipment and electronic gadgets rising parallel yields problem of high energy consumption and demand. To meet this increasing energy demand several approaches have been developed. One approach to meet energy demand is to control energy(More)
BACKGROUNDS In the present study, we aimed to examine the anti-aging properties of human placental hydrolysate (HPE) and dieckol (DE) from Ecklonia cava against free radical scavenging, muscle hypertrophy-related follistatin mRNA expression, amelioration of cognition-related genes and proteins, inhibition of collagenase-regulating genes, and elastinase(More)
Diversified and complicated manufacturing sites make optimal scheduling of production lines difficult. Under current manufacturing processes, it is almost impossible for schedulers to consider all the constraints of production processes. A strategy of simulation-based advanced planning and scheduling (APS) is employed to overcome difficulties that interfere(More)
Location systems are used to track items along manufacturing process. However, the considerable cost from installation and maintenance of the location systems is an obstacle to install the location information system. This research presented a real time location system to overcome the high cost issue. The system is a combination of current location system(More)
Many inference methods of queueing systems have been developed on the basis of Larson's QIE(queue inference engine) with the assumption of homogeneous Poisson arrivals. It inferred the queueing systems with starting and ending times of service. However, the arrival processes are becoming complex lately, so there are some limits to apply the method. Our(More)
