The aim of this study is to analyze the differences in the publicness indices depending on the environmental factors of regional public hospitals to derive the policy implications for improving management for regional public hospitals. The data of the 34 regional public hospitals from 2016 was used for the analysis. Major results of this study are as follows. First, the analysis of the differences in the scores of the medical safety net function showed significantly higher scores for regional public hospitals with a larger location, a larger number of hospitals in a unit area, a larger number of nurses per 100 beds, and the lower management fee ratio. Second, the analysis of the differences in the scores of the unmet healthcare needs showed significantly higher scores for regional public hospitals with a larger number of hospitals in a unit area, and a larger number of beds. Third, the analysis of the differences in the scores of the hospital-specialized services showed significantly higher scores for regional public hospitals with a larger location, a higher financial independence of the local government, a larger number of hospitals in a unit area, a larger number of beds, and a larger number of nurses per 100 beds. Major conclusions of this study are as follows. Consideration should be given to the appropriate number of nurses for each regional public hospital to maximize publicness by providing the appropriate amount of medical services, but not to incur unnecessary labor costs. In addition, efforts should be made to enhance profitability, which can be a means of strengthening publicness, by identifying the minimum administrative expenses required for efficient operation and reducing unnecessary administrative expenses. Finally, it is necessary to identify the appropriate number of beds to meet the needs of the customers and to create maximum profits.

This paper analyzes mobile agent performance in network management compared to the client-server model used in the Simple Network Management Protocol (SNMP). Prototypes of an application that gathers MIB-II (Management Information Base-II) variables have been created and tested on a LAN. After acquiring implementation parameters related to network management and to the mobile agent infrastructure, simulation results have been obtained on large topologies similar in shape to the Internet. Response time results show that mobile agents perform better than SNMP when the number of managed elements ranges between two specific limits, an inferior bound and a superior one, determined by the number of messages that pass through a backbone and by the mobile agent size which grows along with MIB-II variables collected on network elements. The results also show that a significant improvement is achieved when the mobile agent returns or sends data to the management station after visiting a fixed number of nodes.

Depending on the growth of the construction industry, size of construction sites are becoming enlarged, and construction work is becoming diversified as well. However, this increases risks of safety accidents. In order to alleviate this problem, some large construction companies have implemented a Safety Patrol Management System (SPMS) in order to reduce accidents on construction sites. Aimed at the construction sites where SPMS has been applied, the purpose of this research is to calculate the proper number of SPMS safety mangers by comparing and contrasting the number of safety managers per person for each site with different sizes and the converted accident ratio. In addition, we also aim to calculate the adequate amount of SPMS safety management costs compared to the total amount of construction expenses required once SPMS is introduced.

As the business has been highly informatized, many companies has bought the software for their works. There are two types of software license. One is a site license and the other is a user license. This paper is focused on the user license. User license has the number of the right to use software. So, software managers always need to know the number of licenses in use and should limit the number of software license in use. If someone in the company use a software without license, he will be treated as a piracy. In that case, the company should pay for the settlement cost for the exceeding license use. In this paper, we suggest the model how we can limit the installation of the software within the number of licenses by license management system.

The purpose of this study is to analyze the direct relationship between doctors and number of patients to be treated by applying many kinds of IE techniques. Generally, doctors in this research work both at Out Patient Data & In Patient Data. Under the hospital management system that they are applying in, doctor's daily working schedules are instable because the number of OPD patients daily. Therefore, the amount of time they spend for inward patients are variable too. So the numbers of patients have great influence to the whole hospital system management.

We herein consider a stochastic multi-item inventory management problem in which a warehouse sells multiple items with stochastic demand and periodic replenishment from a supplier. Inventory management requires the timing and amounts of orders to be determined. For inventory replenishment, trucks of finite capacity are available. Most inventory management models consider either a single item or assume that multiple items are ordered independently, and whether there is sufficient space in trucks. The order cost is commonly calculated based on the number of carriers and the usage fees of carriers. In this situation, we can reduce future shipments by supplementing items to an order, even if the item is not scheduled to be ordered. On the other hand, we can reduce the average number of items in storage by reducing the order volume and at the risk of running out of stock. The primary variables of interest in the present research are the average number of items in storage, the stock-out volume, and the number of carriers used. We formulate this problem as a multi-objective optimization problem. In a numerical experiment based on actual shipment data, we consider the item shipping characteristics and simulate the warehouse replenishing items coordinately. The results of the simulation indicate that applying a conventional ordering policy individually will not provide effective inventory management.

This paper shows survey result on safety management status of laboratories in Korea. In Korea, many studies and reports on laboratory safety have been published since the ministry of education, science and technology (MEST) enforced the Act on Establishing a Safe Environment of Laboratories (Lab Safety Act) in 2006. The MEST has surveyed status of safety management in institutions subject to Lab Safety Act in 2008 and 2010. According to the survey result, safety management status of universities and colleges has been improved on several factors such as establishment of safety manual and implementation of safety inspection; while the number of safety managers of universities and colleges have increased. However, the difficulties in performing duties of safety managers has increased because the number of exclusive safety managers has decreased. This paper identifies the similarities and differences between Occupational Safety and Health Act and Lab Safety Act on assignment and duties of safety managers; therefore, this paper suggests a standard to determine the number of safety managers and decide whether or not their duties should be exclusive. Besides current standard that is based on the number of researchers, the number of individual laboratories should be considered. The new method would be helpful to determine the number of exclusive safety managers because the amount of safety managers' duties generally do not depend on only the number of people who may be exposed to any risk but also the number of facilities that may be cause of any accident.

Today, many companies have introduced an ERP system - an enterprise resources planning - in order to improve corporate credibility through transparent management and for quick responses to market situations through quick decision making. After the construction of an ERP system, many companies are having difficulty in calculating the appropriate number of personnel required for running the system because of a lack of standard for doing so, as well as a lack of pertinent procedures. As a result, the companies are having to resort to a trial-and-error approach. Therefore this paper studied a model for calculating the appropriate number of personnel required for efficiently running an ERP system after its construction, as well as for constantly meeting its performance targets. The developed model was applied empirically to calculate an appropriate number of personnel required, and an organization was set up according to this. Therefore, the purpose of this study was to present an optimized model for calculating the number of personnel required for operating an ERP system, that which addresses problems of existing models, in order to help companies organize the operation personnel and its size, as well as to provide more objectivity to the calculated number of personnel required and to improve credibility.
