Electronic Records Management System (ERMS) is a computer program or set of applications that is utilized for keeping up to date records along with their storage. ERMS has been extensively utilized for enhancing the performance of academic institutions. The system assists in the planning and decision-making processes, which in turn enhances the competencies. However, although ERMS is significant in supporting the process of decision-making, the majority of organizations have failed to take an initiative to implement it, taking into account that are some implementing it without an appropriate framework, and thus resulted in the practice which does not meet the accepted standard. Therefore, this study identifies the factors influencing the adoption of ERMS among employees of HLI in Yemen and the role of such adoption in the decision-making process, using the Unified Theory of Acceptance and Use of Technology (UTAUT) along with Technology, Organization and Environment (TOE) as the underpinning theories. The study conducts a cross-sectional survey with a questionnaire as the technique for data collection, distributed to 364 participants in various Yemeni public Higher Learning Institutions (HLI). Using AMOS as a statistical method, the findings revealed there are significant and positive relationships between technology factors (effort expectancy, performance expectancy, IT infrastructure and security), organizational factors (top management support, financial support, training, and policy),environmental factors (competitiveness pressure, facilitating conditions and trust) and behavioral intention to adopt ERMS, which in return has a significant relationship with the process of decision-making in HLI. The study also presents a variety of theoretical and empirical contributions that enrich the body of knowledge in the field of technology adoption and the electronic record's domain.

The purpose of this study is to explore the application sphere of BPM(Business Process Management) to e-trade process using BPM technology and its service architecture in order to expand the usage of e-trade platform which is developing. After close reviewing the current status of trade process, the possibility of BPM application by e-trade process will be analyzed. The result of analysis is that BPM application to local L/C and purchasing confirmation process could be implemented because those processes are very suitable to apply standardized process and can minimize the risk and confusion of users. BPM application to remaining trade process have to be considered by mid-term and long-term project with the reflection of pilot project performance. Also this study suggests a business management model of e-trade process based on BPM technology which is the new IT technology and integrated interface in view of trade community.

Information technology's potential for changing processes is widely acknowledged and various information technologies exist as a tool making business reengineering possible. Groupware is one of information technology that typically work in concert to bring out change in processes. This paper attempts to explain the importance of groupware as a critical information technology for business reengineering by developing a methodology of applying groupware to business reengineering. In order to understand the applicability of groupware to business reengineering, this paper has the following objectives. 1) Examines how the capability of groupware can play as a chang lever or enabler of process innovation explicitly. 2) Propose a integrated business reengineering methodology that incorporates process, process environment and information technologies specifically. A case study was used to provide the insight how groupware can play as a enabler of process innovation. The case was analyzed according to the reengineering methodology we proposed.

The present paper aims to give basic information to establish zero emission material cycle including the minimization of emissions from industrial production processes and the area in regional scale. Strategies and methodologies to analyze emissions from the production processes and our human activities and to reduce those emissions by refining and/or replacing the unit process with the alternatives are introduced as well. Quantitative evaluation and management systems of any raw materials and the production process are from vie points of treatment are essential. Estabiishment of a process networking for the recycle of discharged non-products materials by the intra-process, trans-process and the trans-industries are proposed. Procedures and priorities to formulate industrial and regional zero emission system are proposed as well.

기존 생체정보 시스템은 구성 초기에 정의된 생체정보 프로세스가 시스템 실행 후에 변경 없이 정적이고 지속적으로 동일한 프로세스를 수행한다. 그러나 이러한 정적 프로세스는 이동 컴퓨팅을 수행하는 이동 생체정보시스템 응용에 비효율적인 실행을 나타낸다. 특히, 생체정보시스템의 프로세스 구성 및 방법 변경 시에 새로운 정의 및 실행 초기화를 수행해야하는 불편한 업무를 수반하게 된다. 본 연구는 이러한 비효율적 프로세스를 극복하기 위한 방안으로 동적 프로세스 설계 및 실행기법을 제안한다.

Today's firms exist and run business in an uncertain and rapidly changing environment in terms of industry, market, technology, economic conditions, and culture. To be competitive, at least to survive, firms must cope with and manage uncertainty effectively. In other words, firms should be equipped with powerful weapons to capture competitive advantage over their competitors. There are several ways for a firm to capture competitive edge over its competitors such as cost leadership, quality of the products and services, manpower, higher productivity, and technology. Among these, technology, especially information technology, could be the most effective weapon for competitive advantages since it is possible to monitor competitors' movement as well as to provide appropriate information with both planning and control phases through an information system. In this paper, a competitive weapon in action, a Process Control System which is developed by and installed at a U.S petroleum company would the described.

We have investigated the structural, electrical and optical properties of Al-doped ZnO (AZO) thin films grown on glass substrate by pulsed DC magnetron sputtering as functions of pulse frequency and substrate temperature. A highly c-axis oriented AZO thin film is grown in perpendicular to the substrate when pulse frequency of 30 kHz and substrate temperature of $400^{\circ}C$ was applied. Under this optimized growth condition, the resistivity of AZO thin films exhibited $7.40\times 10^{-4}\Omega \textrm{cm}$. This indicated that the decrease of film resistivity resulted from the improvement of film crystallinity. The optical transmittance spectra of the films showed a very high transmittance of 85∼90 % in the visible wavelength region and exhibited the absorption edge of about 350 nm. The results show the potential application for transparent conductivity oxide (TCO) thin films.

In this paper, a design of I-PDA controller by CDM to control a flow process whose structure is first order lag plus a dead time is introduced. The factor of dead time of the process is approximated by second order Pade approximation in order to get a third order system. The simulations show that both of the transient and steady state specifications can be fulfilled. However, the transient response of the I-PDA control system still has long rise time. Then, a feedforward controller (FFC) with two adjustable parameters and one derivative time is introduced into I-PDA control system for improving the speed of the system response. It is shown, from the simulation results, that the performance of the I-PDA control system with suitable FFC has shorter rise time and no overshoot, while settling time remains almost the same. The performance comparison of the proposed control system with the PI control system with and without FFC is also made.
