This study discusses the operating systems upgrade to motivation of windows users. To discuss this issues, research hypotheses were set based on Unified Theory of Acceptance Use of Technology(UTAUT) and Theory of Reasoned Action(TRA). The data were collected from undergraduate students. Total of 199 data were used for the analysis. The results of the analysis were summarized into two ways. first, performance expectancy and effort expectancy has a positive influence on attitude towards upgrade the operating systems. Second, social influence, facilitating conditions, and attitude had a positive influence on intention towards upgrade the operating systems. Thus, when users perceived a high degree of performance expectancy, effort expectancy, social influence, and facilitating conditions towards upgrade the operating systems, they evaluated more positively the upgrade the operating systems.

Many enterprises have implemented packaged enterprise resource planning (ERP) solutions rather than system development on the promises of feasible strategic benefits. Typical feasible benefits include adoption of global standards and processes through a proven integrated system, continuous version upgrading by vendors, and thus the easiness of system maintenance. The objectives of this research are to identify what makes a post-implementation success of ERP system and to figure out the critical issues and factors for the successful upgrade of packaged ERP systems. This case study was conducted based on five different organizations that have experienced system upgrade implementation. Success factors of ERP system upgrade include (1) clear statement of upgrade goals, (2) good coordination and communication among the implementation partners, (3) thorough management of customization and maintenance history including documentation, (4) Planning of system requirements of higher version, and (5) redefinition of role between business departments and IT department.

This paper introduces a new web based method to remotely upgrade firmwares of Cable Modems (CM) which are integral part in providing high-speed Internet access through Hybrid Fiber Coaxial (HFC) networks. Also, it discusses various practical problems arising in the upgrading process. Traditional upgrade has been performed by modifying the CM configuration fie. This paper shows a new web based CM firmware upgrade method using SNMP and MIB which greatly reduces upgrading time, cost and man-hour than traditional firmware upgrade methods. This method has been shown to be very efficient and practical. This method will make significant impact especially because tens of million cable modems are currently waiting to be upgraded soon to the next version from the current version.

The firmware upgrade, which is remotely performed, is an essential function in smart metering or AMI (Advanced Metering Infrastructure). In other words, the AMI software and firmware can be switched for maintaining and improvement without replacement of H/W devices in AMI environment. Also, if number and type of devices are increase, the demand of remote update service will be increased. Through the firmware upgrade service remotely, the electric power corporation may be able to benefit various fields. For example, there are to adapt more easily in many environments, real-time service and to cut maintenance costs. In this paper, we proposed to design an international level FUMS(Firmware Upgrade Management System) which includes requirement function, architecture and protocol related with DCU, Smart Meter.

In this paper, we have implemented the device management system to upgrade T-PAK software in mobile phone. The hybrid scheduling method and selective upgrade method are proposed. Hybrid scheduling method is based on distribution of delivery data in accordance with network traffic load and service priority from device management server to mobile phone. Selective upgrade method manages DSL classified by T-PAK software version to be upgrade using version management established in OMA DM SCOMO. Key mechanism of selective upgrade method is to only deliver DSL to be replaced to the mobile phone. We made an experiment on two methods using MS-700T terminals. The experimental result shows that the proposed method is faster than normal from delivery time standpoint.

The Jiangyin Bridge is a suspension bridge with a main span of 1385 m over the Yangtze River in Jiangsu Province, China. Being the first bridge with a main span exceeding 1 km in Chinese mainland, it had been instrumented with a structural health monitoring (SHM) system when completed in 1999. After operation for several years, it was found with malfunction in sensors and data acquisition units, and insufficient sensors to provide necessary information for structural health evaluation. This study reports the SHM system upgrade project on the Jiangyin Bridge. Although implementations of SHM system have been reported worldwide, few studies are available on the upgrade of SHM system so far. Recognizing this, the upgrade of original SHM system for the bridge is first discussed in detail. Especially, lessons learned from the original SHM system are applied to the design of upgraded SHM system right away. Then, performance assessment of the bridge, including: (i) characterization of temperature profiles and effects; (ii) recognition of wind characteristics and effects; and (iii) identification of modal properties, is carried out by making use of the long-term monitoring data obtained from the upgraded SHM system. Emphasis is placed on the verification of design assumptions and prediction of bridge behavior or extreme responses. The results may provide the baseline for structural health evaluation.

In this paper, we propose a structure of 800bps high speed router and a gigabit Ethernet line interface board. Having Programmability, network processor is applied to gjgabit Ethernet line interface board. Also, we propose a new method to upgrade image files that consist of operating system and drivers. It is possible to upgrade image files for several boards at once and to reduce the elapsed time for image upgrade using tile proposed method.

The PLS-II, the major upgrade program of the PLS (Pohang Light Source, a 2.5-GeV 3rd generation light source), is planned at the Pohang Accelerator Laboratory. Given the glaring lack of normative data regarding the PLS-II the major upgrade, this study can be seen as the first in a needed stream of research investigating selection by dual gun and dc electron gun. Usable electron gun can think method to use dual electron gun and method to prove energy by existing electron gun in energy increase. This article is concerned with the formal classification of used of pre-injector electron gun type of the DC and pulse. Design concept wishes to show contents that design for pulse type of power supply and DC type of electron gun.

Micro jetting drop inspection system is essential to measuring micro drop volume. Measuring pico-liter drop volume is useful for new LCD color filter product process that is based on inkjet printing technology. To upgrade the reliability in drop measurement system, we use the auto focusing & multi drop reiteration & blurring average algorism. First of all we used standard mark for gage R&R in the vision system. Finding the most suitable threshold for multi blurring drop, is the main key of this research. Sensitivity of vision system is a standard in measuring the upgrade system level. So, suitable threshold can upgrade the performance of jetting drop inspection system.
