Purpose - This empirical study, aims to identify the determinants of adoption and acceptance of mobile payment as to understand why it is successful in some countries in Sub-Saharan Africa but failing in others. A comparative study of a successful mobile payment service and a purported failed one was done as to have some insights to the factors affecting acceptance of the technology. Design/methodology/approach - The strength of three notable theories: theory of diffusion of innovation (DOI), the extended unified theory of user acceptance of information technology (UTAUT2) and self-efficacy theory were use. The self-efficacy of government support inclusion as, a moderating variable in the form of infrastructure, securing transaction and price value revealed the relevance of government in the success of mobile payment service. By means of a field survey of 705 subjects in two separate regions of Africa (East and West), the data was collected and use to test the research model. Findings - The study result shows the importance of the moderating factor of government support to the success of mobile payment of any nation. The result also shows the importance of the perception of relative advantage, compatibility, complexity, social influence as already revealed by other studies. Research implications or Originality - Mobile payment success in some part of Sub-Saharan Africa is well known but also suggested to fail in some Sub-Saharan African countries. Buttressing the need for understanding of the factors affecting mobile payment acceptance. This article empirically examined the factors influencing the success of mobile payment, and we implicated that if the implementation of mobile payment is to be successful for mobile commerce in any nation, adoption, acceptance and use by its citizen is imperative.

It has been asserted that per diem payment system should be introduced, in place of the current fee-for-service system, for payment of the inpatient services of the geriatric hospitals, Based on the assentation, this study aims at calculating costs and profits per inpatient-day of the geriatric hospitals, and thereby at contributing to the managerial improvement from the both sides of the Government and the hospitals. Relevant data of the three months, May to August, 2002 were collected from the five geriatric hospitals, and per inpatient-day costs and profits were calculated for the three disease groups. Major results and conclusions are as follow : Firstly, total costs per insured inpatient-day of the geriatric hospitals are 65, 389 won for dementia (including optimal profit of 3,858 won), 69,730 won for stroke (including optimal profit of 4,117 won), and 70,085 won for other diseases (including optimal profit of 4,134 won). Secondly, the amount of the non-insured costs per inpatient-day occupies 34.5% of the total costs for dementia, 30.3% for stroke, and 30.1% for other diseases. Thirdly, the total amount of the per inpatient-day costs calculated including the optimal profits is, on the average, higher by 12% than the present price level calculated for the current fee-far-service system. This implies that the present price level should rise by 12% when the current fee-far-service payment system be maintained, and Finally, introduction of a sliding-scale payment system should be considered for the inpatient medical management fees for the length of stay over six months or more that are being cut in the claim examination process by the insurance corporation.

Section I of Chapter III ('Obligations of the Buyer') in Part III ('Sale of Goods') of the CISG consists of six articles addressing one of the fundamental buyer obligations described in article 53 of the CISG: the obligation to pay the price. Although the amount of the price that the buyer must pay is usually specified in the contract, two articles in Section I contain rules governing the amount of the price in particular special circumstances: article 55 specifies a price when one is not fixed or provided for in the contract, and article 56 specifies the way to determine the price when it is 'fixed according to the weight of the goods'. The remaining four provisions in Section I relate to the manner of paying the price: they include rules on the buyer's obligation to take steps preparatory to and to comply with formalities required for paying the price (article 54); provisions on the place of payment (article 57) and the time for payment (article 58); and an article dispensing with the need for a formal demand for payment by the seller (article 59). Especially article 53 states the principal obligations of the buyer, and serves as an introduction to the provisions of Chapter III. As the CISG does not define what constitutes a 'sale of goods', article 53, in combination with article 30, also sheds light on this matter. The principal obligations of the buyer are to pay the price for and take delivery of the goods 'as required by the contract and this CISG'. From this phrase, as well as from article six of the CISG, it follows that, where the contract provides for the performance to take place in a manner that differs from that set forth in the CISG, the parties' agreement prevails.

This study reports UTIS(Urban Traffic Information System), which has been generalized in developed countries through brisk research and development and is being promoted for introduction by National Police Agency and Road Traffic Authority to reduce the astronomical amount of social expenses including traffic congestion expenses. Also this study investigates the proper charges for using by the preestimate of demand and contentment according to methods of payment after the service is introduced. The results of this study are as follows. First, demand forecast model is constructed by Binary Logit Model. Second, forecast models of using aspects of UTIS service according to methods of payment are established by Ordered Probit Model. Third, the proper charges for using of UTIS service according to methods of payment are presented to the supplier in the aspects of users. For this, preferences by using aspects and methods of payment are captured. And unit elasticity of coefficient of utilization is understood through responsiveness analysis according to methods of payment.

We present the user-friendly graphical user interface design and implementation of Monte Carlo simulation (MCS) for computing option price of the four-underlying asset step-down equity linked securities (ELS) using the Android platform. The ELS has been one of the most important and influential financial products in South Korea. Most ELS products are based on one-, two-, and three-underlying assets. However, currently there is a demand for higher coupon payment from ELS products because of the increased interest rate in financial market. In order to allow the investors to have higher coupon payment, it is necessary to design a multi-asset ELS such as four-asset step-down ELS. We conduct the computational experiments to demonstrate the performance of the Android platform for pricing four-asset step-down ELS. Furthermore, we perform a comparison test with a three-asset step-down ELS.

Smart grid (SG) technology is now elevating the conventional power grid system to one that functions more cooperatively, responsively, and economically. When applied in an SG the demand side management (DSM) technique can improve its reliability by dynamically changing electricity consumption or rescheduling it. In this paper, we propose a new SG scheduling scheme that uses the DSM technique. To achieve effective SG management, we adopt a mixed pricing strategy based on the Rubinstein-Stahl bargaining game and a repeated game model. The proposed game-based pricing strategy provides energy routing for effective energy sharing and allows consumers to make informed decisions regarding their power consumption. Our approach can encourage consumers to schedule their power consumption profiles independently while minimizing their payment and the peak-to-average ratio (PAR). Through a simulation study, it is demonstrated that the proposed scheme can obtain a better performance than other existing schemes in terms of power consumption, price, average payment, etc.

This paper presents the optimal scheduling of hourly consumption in a residential community (community, neighborhood, etc.) based on real-time electricity price. The residential community encompasses individual residential loads, communal (shared) loads, and local generation. Community-aggregated loads, which include residential and communal loads, are modeled as fixed, adjustable, shiftable, and storage loads. The objective of the optimal load scheduling problem is to minimize the community-aggregated electricity payment considering the convenience of individual residents and hourly community load characteristics. Limitations are included on the hourly utility load (defined as community-aggregated load minus the local generation) that is imported from the utility grid. Lagrangian relaxation (LR) is applied to decouple the utility constraint and provide tractable subproblems. The decomposed subproblems are formulated as mixed-integer programming (MIP) problems. The proposed model would be used by community master controllers to optimize the utility load schedule and minimize the community-aggregated electricity payment. Illustrative optimal load scheduling examples of a single resident as well as an aggregated community including 200 residents are presented to show the efficiency of the proposed method based on real-time electricity price.

This paper discusses the components of a guaranteed maximum price (GMP) and proposes a framework for the development of GMPs as contract payment provisions for construction manager-at-risk (CMR) and design-build (DB) contracts for transportation projects. The framework is the synthesis of a comprehensive literature review, a content analysis of CMR and DB solicitation documents and contracts, and case study project output from twelve projects in nine states worth $3.1 billion. The research also discusses the development of three common types of contingencies that are often utilized in projects with GMPs. The study concludes that owners should specify the structure of the GMP and its components to enhance clarity and understanding of the GMP's composition. It recommends that this structure be included in the CMR and DB solicitation documents so that pricing proposals can be formulated in a manner that is consistent with the contract payment provisions that will be useful to practitioners that need to implement GMP-based contracts.
