The damage to the security is increasing as public key-based ISP secure payment service is used in online banking payment system. Security technology aspect to ISP secure payment security has no special problems. But, security damage that occurs due to the simplicity of the payment system is a problem. In this paper, we propose response and plan for ISP secure payment service to minimize the damage that occurs due to the simplicity of a security settlement system. Proposed scheme is applicable to various billing systems such as secure payments, online payment, mobile payment, credit card. Proposed scheme is characterized in that can stably support the capabilities of the new billing system. Also, proposed scheme is to analyze the various security threats arising from the payment of the financial services and to describe response and plan technology.

Arduino is one of the open source microcontroller projects, and Arduino boards using AVR microcontrollers are commonly used. In general, AVR microcontrollers use ISP (In System Programming) upload, but in Arduino, serial upload through a bootloader is basically used, and a dedicated microcontroller is built into the board for this purpose. In order to use the ISP upload in Arduino, a dedicated upload device is required, which is not included in the Arduino board. In this paper, we propose a unified programmer that can handle ISP upload and serial upload through one dedicated microcontroller, and show that ISP and serial upload are possible using the unified programmer. In addition, the proposed unified programmer works as a USB-serial converter, supports serial communication with a computer, and it is also possible to burn the Arduino bootloader. All operations of the unified programmer can be confirmed through the experimental results.

Many problems and complaints have been caused by applying the UCP to the standby credit. To solve the problem, International Standby Practices were established. ISP and UCP are similar in that both of them generally regulate the transaction of credit. However, when the ISP is compared with the UCP, the following features are found : 1. In the UCP, when Force Majeure such as acts of God or strikes cause temporary work stoppage, the expiration date cannot be extended. In the ISP, the expiration date can be extended to 30 days afte the place for presentation re-opens for business in the same situation. 2. The UCP does not specify who the issuer of a document must be because there can be many issuers of documents. In the ISP, it is specified that all required documents are to be issued by the beneficiary. 3. In the UCP, compliance between presented documents is required. In the ISP, a discrepancy between presented documents is allowed. 4. In the UCP, if drawings and/or shipments are required by a credit to be made in instalments, and a required drawing/instalment is not made, the credit ceases to be available for any subsequent instalment. In ISP, there is no loss of effect and no influence on the right of beneficiaries, even in the same situation. 5. In the UCP, multiple transfers are not permitted, but partial transfers are. ISP states just the opposite. Multiple transfers are permitted, but partial transfers are not. 6 The UCP obligate each bank (issuer, confirming and nominated bank) to complete their review within a 'reasonable time' but not more than seven banking days. In the ISP, less than three business days is deemed to be not unreasonable and more than seven days is deemed to be unreasonable. 7. ISP, unlike UCP, recognizes that issuers and confirmers may spread their risk through syndication and participation of standby credits. However, the thing to remember is that the ISP should be reviewed carefully before application. If necessary, a partial addition or modifications can be made. Usually, the best advantage of the ISP is given to the issuers. A positive use of the ISP can be made by issuers but, applicants should consider using the UCP to the their rights and duties.

E-business might be characterized by open system through internet, fortification of relationship between the suppliers and customers in chain system of company, the collaboration among partners and the use of IT. For these characteristics, e-business companies are becoming to suffer such burdens as wide spread of global economy, industry deregulation, and the increasing number of new entrants. In this situation, e-business companies should maintain the flexible system to adapt fast changing environment. Information system planning has been the important research area for many years because of its strategic importance. Among various variables, organization and IS context have been researched for making successful ouput of ISP. In this paper, I studied the importance of flexibility in e-business environments. And further I examined the flexibility of IS, organization and ISP methodologies. The forthcoming paper, I expect to investigate the relationship between IS flexibility, organizational flexibility, ISP flexible methodologies and successful ISP.

Information strategy planning (ISP) pursues alignment of business strategy and IT (Information Technology) strategy as well as derivation of feasible and valuable IT projects. However, conventional ISP methodology hardly obtains the objectives because of its intrinsic shortcomings. Diverse ways are proposed for the improvement of the conventional methodology including, for example, combination of EA (Enterprise Architecture) with ISP. Meanwhile, six-sigma methodology which is characterized by quantification, scientific and systematic approach, customer orientation, process orientation has been gaining considerable attention and extending its application scope continuously. In this paper, an innovative ISP methodology is proposed by decomposing activities, methods, and tasks from conventional ISP process and reorganizing them into DMADOV six-sigma framework. In addition, the usefulness and applicability of the newly proposed methodology are provided using an electronics company example. The methodology enhance the possibility of producing future oriented and beneficial IT projects by associating IT strategy and the projects in the form of quantified causal relationship. Besides, it can also increase the objectivity of IT vision and strategy.

ISP(Information Strategy Planning 이하 ISP) 기반의 프로젝트는 실행예산과 일정계획을 구체적으로 산출된다. 그러나 EA(Enterprise Architecture 이하 EA) 에서는 아직까지 이 부문에 대해 명확한 요구와 산출물을 고객에게 제공하지 못하고 있다. 현재 EA 사업의 특성은 IT 와 경영전략이 연계된 모습이 아니라 예산과 객관적인 외부 컨설팅이라는 발주자(부서)의 예산사용 당위성 증명을 위한 측면의 EA접근이 많다. 그러나 EA는 IT와 관련된 길잡이(표준/가이드)의 역할을 주요 관점으로 한다. 발주자와의 요구와는 이견(gap)이 생기게 된다. EA 프로젝트에서는 이러한 문제를 해결하기 위해 ISP 프로젝트의 절차를 EA 산출물과 결합해서 프로젝트를 수행한다. 본 논문은 실제 프로젝트를 통해 EA 바탕에서 ISP의 실행예산과 일정계획이 적용된 사례이다.

Understanding what lies beneath the relationship between ISP and its implementation is an significant area of inquiry in the ISP research. Through an empirical analysis and complementary case examples the current study examines this relationship at six different university sites which undergone both of these processes years from 1995 to 2001. The face-to-face, in-depth interviews were conducted to those participated in both of these processes. A questionnaire survey was also conducted to same participants to elevate the quality of the validity and reliability of the measures. Due to the limitation of the access to the data, it was not possible to compare how similar the final implementation outcomes are from what was originally planned in ISP to some sites. However the study finds that such organizational factors as management support, communication, and organizational culture at the ISP play an important role in the implementation process. This paper proposes that these organizational factors although little they seem to directly affect each individual elements in the implementation process, its latent impact is critical as a whole.

As a way to overcome the problems that when you transmit data to and receive data from End Device to participate in the GRID network, QoS has not been, GARA supports the Diffserv system basically. However, the problem when it is assumed settings related to the Diffserv between the ISP and the ISP is wrong with each other, that it is not possible to receive a complete QoS services began to appear. In this paper, we tried to overcome these drawbacks, in networks based GARA the (Globus Architecture for Reservation and Allocation), using the SLA (Service Level Agrement) server, was treated in the highest priority to the data, the ISP there is provided a method for setting the Diffserv the ISP is even wrong and, using the TOS of the IP header, to solve this, it is described about the direction of future research.

The applicability of network-based computing depends on the availability of the underlying network bandwidth. Such a growing gap between the capacity of the backbone network and the end users' needs results in a serious bottleneck of the access network in between. As a result, ISP incurs disadvantages in their business. If this situation is known to ISP in advance, or if ISP is able to predict traffic volume end-to-end link high-load zone, ISP and end users would be able to decrease the gap for ISP service quality. In this paper, simulation tools, such as ACE, ADM, and Flow Analysis, were used to be able to perceive traffic volume prediction and end-to-end link high-load zone. In using these simulation tools, we were able to estimate sequential transaction in real-network for e-Commerce. We also imported virtual network environment estimated network data, and create background traffic. In a virtual network environment like this, we were able to find out simulation results for traffic volume prediction and end-to-end link high-load zone according to the increase in the number of users based on virtual network environment.
