Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone. Thus, we obtain the Evolution Model for creating the advanced information-technical system.

To deal with the major challenges of embedded sensor networks, we consider the use of magnetic fields as a means of reliably transferring both information and power to embedded sensors. We focus on a power allocation strategy for an orthogonal frequency-division multiplexing system to maximize the transferred power under the required information capacity and total available power constraints. First, we consider the case of a co-receiver, where information and power can be extracted from the same signal. In this case, we find an optimal power allocation (OPA) and provide the upper bound of achievable transferred power and capacity pairs. However, the exact calculation of the OPA is computationally complex. Thus, we propose a low-complexity power reallocation algorithm. For practical consideration, we consider the case of a separated receiver (where information and power are transferred separately through different resources) and propose two heuristic power allocation algorithms. Through simulations using the Agilent Advanced Design System and Ansoft High Frequency Structure Simulator, we validate the magnetic-inductive channel characteristic. In addition, we show the performances of the proposed algorithms by providing achievable ${\eta}$-C regions.

Commerce activities which are free form space and time constraint using a communication network are called Electronic Commerce(EC). Because of sending a commercial information using open network such as Internet in EC, they need the security of commerce information (payment information and purchase information), checking the integrity of transferring data and certifying all parts participated in commerce for a secure commerce. Recently Visa and MasterCard Co. released the Secure Electronic Transaction (SET) Protocol for secure payment card transaction on Internet. This paper proposes a Secure Electronic Commerce Transaction Model(SECTM) using SET in order to support the secure commerce on Internet. The proposed transaction model prevents merchant from abusing the cardholder's payment information (credit-card number etc.) and enables cardholder to shop securely in Electronic Shopping Mall.

In order to send the information certainly via the network against the packet lost caused by hardware troubles or limitation of packet transferring, we must construct reliable network infrastructure. However, it is difficult to construct comfortable network early if we construct rely on the prediction or the experience through a lot of troubles. In this paper, we propose the method to construct reliable network infrastructure based on the computer network simulation. This simulation is based on the percolation model. Percolation model is known as the model that represents connections. We gave some simulations for the various network topologies: the square lattice network, the cubic lattice network, and the full connection type network.

Web Services are rapidity becoming the enabling technology of today's e-business and e-commerce systems, and will soon transform the Web into distributed applications. The aim of this paper is to present our approach in applying Web Services into the Internet transaction banking system. The system is integrated among backend system of banks so that each bank system can communicate with each other in order to perform transactions in transferring money from an account in one bank to an account in the partner bank and vise versa. The backend systems of banks are heterogeneous information systems; therefore it is difficult to build a common environment using existing distributed technologies. Web Services provide a means for different organizations to connect their applications with one another to conduct business across a network in a platform and language independent manner [1]. The paper will examine these benefits of Web Services and apply these features into the Internet banking transaction system regardless of platform, programming languages as well as existing backend system of banks.

This paper presents a wafer motion modeling of the transfer unit and the control unit in the clean tube system, which was developed as a means for transferring the air-floated wafers inside the closed tube filled with the super clean airs. The motion in the transfer unit is modeled as a mass-spring-damper system where the recovering force by air jets issued from the perforated plate is modeled as a linear spring. The motion in the control unit is also modeled as another mass-spring-damper system, but in two dimensional systems. Experiments with a clean tube system built for 12-inch wafers show the validity of the presented force and motion models.

Documenting work-in-progress on construction sites using images captured with smartphones, point-and-shoot cameras, and Unmanned Aerial Vehicles (UAVs) has gained significant popularity among practitioners. The spatial and temporal density of these large-scale site image collections and the availability of 4D Building Information Models (BIM) provide a unique opportunity to develop BIM-driven visual analytics that can quickly and easily detect and visualize construction progress deviations. Building on these emerging sources of information this paper presents a pipeline for model-driven visual analytics of construction progress. It particularly focuses on the following key steps: 1) capturing, transferring, and storing images; 2) BIM-driven analytics to identify performance deviations, and 3) visualizations that enable root-cause assessments on performance deviations. The information requirements, and the challenges and opportunities for improvements in data collection, plan preparations, progress deviation analysis particularly under limited visibility, and transforming identified deviations into performance metrics to enable root-cause assessments are discussed using several real world case studies.

현재 IT 기술의 발전에 힘입어 선박 내에 발생하는 전자 데이터를 통해 선박 제어, 자율 운항, 상황 발생 시 정보 제공 등의 기능을 할 수 있는 전자 운항 선박이 등장하였다. 국내 선박용 항해 통신 장비 업체들에서 제작된 장비들은 NMEA 0183 표준 규격을 따르고 있다. 그러나, 이러한 표준규격 내에서의 저속의 데이터 전송으로 인한 향후 NMEA-2000에서의 멀티미디어 전송 및 USN 장비 호환을 위해서는 보다 효율적인 전송 처리 방안이 필요하며, 나아가 이더넷을 기반으로 하는 선박 제어가 필요로 하게 된다. 이러한 문제를 해결하기 위해서는 저속과 고속 데이터 전송시에 보다 효율적인 전송 방안을 고려하여야 하며, 또한 그러한 방안이 기존의 선박 전자 장비와 원활히 연동될 수 있도록 고려하여야 한다.
