Korean health insurance has adopted preliminary DRG payment system through 8 DRGs from 1997. But present DRG payment system gives economic incentives for hospitals to hire less nurse. This study was attempted to develope DRG adjust index to differentiate DRG price by nurse staffing level for nursing care quality. Method: We analyzed inpatient care cost by medical institute and developed DRG adjust index to differentiate DRG price by nurse staffing level. Results: Among same medical institute, inpatient care cost are very different according to hospital's nurse staffing level. In the case of casarean section, inpatient care cost of the 1st grade general hospital are more expensive 85,732won than the 6th grade hospital. The cost difference are 8.24% of total casarean section DRG price and 16.48% of DTG variable price. We developed DRG adjust index-a to apply DRG variable price and index-b to apply DRG total price for compensation cost difference of hospitals. Conclusions: DRG price adjust index will give economic incentive for hospitals to hire more nurse and improve nursing care quality.

Purpose: The purpose of this study was to explore the relationship between cost and revenue for inpatient nursing activities in general wards. Methods: Data were collected from 12 medical-surgical wards in one general hospital from January 1 to December 31, 2010. The nursing activities were categorized into 2 groups according to nursing service payment type in terms of the Korea health insurance system. Descriptive statistics were used to identify nursing activities and nursing activity costs. Results: Of 140 nursing activities identified as performed in general wards, payment for 69 items was included in nursing management fees. The percentage of each cost for the nursing units was 90% for labor, 4% for materials, and 6% for operating expenses. The cost for medical support nursing service accounted for 38% of costs and nursing management fees, 62%. The average profit and loss was -237,257,000 won. The cost recovery rate for nursing service was only 44%. Conclusion: The results indicate a need to measure the economic value of nursing activities performed in general wards and use it as a basis for establishing an adequate reimbursement system for nursing service.

In a cost based pool market, the generation capacity can be used as strategic bids by generation companies (Gencos) with the cost functions open to the market. Competition using strategic capacities is modeled by Cournot and Perfect Competiton (PC) model, and transformed into two by two payoff matrix game with Gencos' decision variables of Cournot and PC model. The payoff matrices vary when capacity payments are given to Gencos in accordance with their capacity bids. Nash Equilibrium (NE) in the matrices also moves with capacity price changes. In order to maximize social welfare of the market, NE should locate in a certain position of the payoff matrices, which corresponds to a PC NE. A concept of a critical capacity price is proposed and calculated in this paper that is defined as a minimum capacity price leading to PC NE. The critical capacity price is verified to work as a tool for suppressing a strategic capacity withholding in simulations of a test system.

In this study, medium capacity EHP and GHP for air-conditioning a building with a floor area of $1,200\;m^2$ are compared economically. To consider all the factors of initial and operation costs effectively, an annual equal payment method is proposed. For the initial cost, equipment, construction, installation, electric facility, financial subsidy and tax cut are considered. Basic electricity, energy(electricity and gas), space charge, labor, insurance and repair are considered for the operation cost. Under the assumptions made in this study, overall cost of EHP is less than that of GHP. However, different outcome may result if different assumptions are made. This study is useful for performing an economic evaluation of various air-conditioning systems.

This study aims to examine the factors that affect the intention of merchants to adopt mobile payments in Saudi Arabia. The underlying model used in the study is the technology acceptance model, which includes two factors: perceived ease of use and perceived usefulness. The effects of trust, cost, and compatibility are also examined because these are among the common factors used based on the literature. An online questionnaire was completed by 242 merchants in Saudi Arabia who had already adopted mobile payment services. A significant relationship was identified between perceived usefulness and compatibility in terms of merchants' intention to adopt mobile payment systems, while an insignificant relationship was identified with perceived ease of use, trust, and cost.

Background: To explore the hospitalizations of breast cancer patients undergoing mastectomy, and to provide a basis for management, clinical prevention and treatment. Materials and Methods: We conducted an investigation by means of the retrospective survey and the medical records retrieval system, and made out the data of patients suffered from breast cancer in a hospital in Guangzhou from 2004 to 2013, including age, medical payment methods, pathological type, treatment, treatment results, complications, hospitalization days, cost and so on. Results: The average age of the inpatients was 50.14 years old. The main histologic types were infiltrating duct carcinoma (88.06%). The main surgery was modified radical mastectomy (80.41%). The cure rate was 90.80% during the 10 years. The main medical payment method was self-paying (57.28%). The average hospital stay was 13.51 days, and average hospitalization cost was RMB 23,083.66 yuan, proportion of drug fees up to 39.70%. Postoperative complication rate was 0.79%. The self-paying group was with the highest proportion of drug fees (P<0.05), while the free medical service group was with the longest hospitalization days (P<0.05). Conclusions: The payment methods significantly affected the proportion of drug fees and hospitalization days. The therapeutic effect was satisfactory with less complications and reasonable proportion of drug fees in our hospital.

Purpose The purpose of this study is to investigate which decision factors continue to use the service based on the online simple payment service. In this study, we will examine how to activate the service from the continuing factors through the dual-model theory consisting of personal dedication and constraint dedication which are frequently used in relation marketing. Design/methodology/approach In this study, we investigated the activation of online simple settlement service using factors affecting the preference of the simple payment service based on the dual-model of dedication-based mechanism and constraint-based mechanism. Findings This study confirmed that customer satisfaction and convenience under the dedication -based mechanism were found to be linked to the preference of the simple payment service. Switching cost under the constraint - based mechanism showed that the customer had no binding ability to continue using the service of the current provider. Likewise, preference was found to have a direct effect on the actual frequency of use of the simple payment service, the number of uses compared to the total number of online payments, and willingness to use more.

Advances in information and communication technology have introduced self-service technologies (SSTs) to service companies, changing the way they serve. In addition, as SSTs are expanding for low cost and high efficiency, opportunities for technology to interact with consumers have increased. Restaurant managers have the advantage of the SSTs win-win strategy, which allows consumers to freely receive the products or services they want, but some consumers have low satisfaction of the SSTs, especially elder people and the blind. This study examines the effect of unmanned order payment technology on service quality evaluation. For this, we interviewed a total of 12 consumers in their 10s to 50s with the experiences of using unmanned order payment technology, applying the Grounded Theory Method(GTM). Through a review of the research participant interview materials, totally 84 concepts were derived and the concepts were analyzed to derive 15 subcategories and 10 upper categories. Finally, a paradigm model of the effect of unmanned order payment technology on service quality assessment was derived. It also found the importance of consumers' sense of obligation to use unmanned order payment technology, recognition of advantages (e.g., time savings), recognition of shadow labor, and recognition of whether the technology usage process is in the service quality assessment stage.

The purpose of this paper is to examine whether the international electronic payment system through IDENTRUS can be active in the future or not. For this purpose, we have reviewed the various aspects of the typical systems : their types, operational mechanisms and actual limitations in real trade. Then we have proceeded to examine the distinguished features of IDENTRUS in terms of operational procedures and characteristics by comparing to other systems. Specially as the preconditions of activation, the possibilities of cost down, time reduction, risk hedging and operational efficiency have been studied. Thus we are not sure that the IDENTRUS will have a position as a main stream in the future electronic payment system, but this system would contribute positively to the establishment of electronic payment system if some functional additions will follow.
