Purpose This study examines the roles of firm-level IT competence in the relationship between marketing orientation and marketing performance in the context of Chinese SMEs. To achieve this goal, this study presents and empirically tests a model of how competitor orientation and customer orientation can be exploited to positively influence marketing performance through IT competence. Design/methodology/approach The competitor orientation and customer orientation are based on the market orientation construct developed by Trainor et al. (2011). IT competence re based on the market orientation construct developed by Reitz et al. 2018) and the marketing performance are based on the performance construct developed by Hooley et al., (2005). To complete the investigation, we conducted a survey in China from February 2019 to April 2019. Randomly contacted 150 Chinese SMEs, including SMEs of all sizes and types. To test our hypotheses, partial least squares (PLS) method was employed. Findings The findings indicate that customer orientation is antecedent to IT competence, while competitor orientation has no significant relationship with IT competence. This study provides a better understanding of the connection between IT competence and firm performance. So companies should focus on shaping customer-oriented culture and training IT competence.

Recently the application area of wireless LAN has been increased, rapidly. The application area was limited in indoor, but as the data throughput and performance of wireless LAN becomes better the application is to extend to the Internet connection and wireless(Ubiqitous) bridge in outdoor. In this paper, In this paper, the data throughput of wireless LAN in mobile environment is measured, and the usability of wireless LAN for develop bridge health monitoring system is confirmed.

The domestic construction industry need to do productivity improvement through technology development than improvement of manpower control or system and develop competitive power through technology in international construction market. Upon this, government for elevation of technological level enacts and operates the advanced construction technology endorsement system but is not looking at effect as that the actual use-results also expected first. Therefore, in this paper, present improvement and direction for activation plan of construction new technology development through comparison with other connection system, literature investigation and questionnaire after grasp present condition of the advanced construction technology endorsement system with specialty construction company as the central figure which occupy most of appointed new technology.

This study was conducted the management of a water level through the water sensor, the waterline and the drain applied to the rice paddy. The gateway transfers the information to oneM2M(: Machine to Machine) platform of IoT(: Internet of Thing) standards to the height of the water level sensor information through the LoRa connection. Depending on the water level requested by the IoT platform, the gateway is to On or Off waterline or drain motor switch and send the information of the water level sensor. IoT platform performs the intelligent application function according to the condition of the water level.

As various portable digital devices are developed, the space of the TV audience is expanding. We propose a structure of broadcasting control in VOD service in which viewers can resume the viewing of digital broadcasting contents in different devices after they have stopped the viewing to move to another place. Then we design a session and resource management system of VOD for this control. In particular, we design the session management of each consumer and simulate the seamless VOD connection model.

Recently, the importance of plant maintenance(PM) was highly raised to provide efficient plant operation which highly affects the productivity. For this reason, a number of engineering methodologies, such as riskbased inspection(RBI), fitness for service guidelines(FFS), plant lifecycle management(PLM), have been applied to improve the plant operation efficiency. Also, a network-based business operation system, which is called ERP(Enterprise Resource Planning), has been introduced in the field of plant maintenance. However, there was no attempt to connect engineering methodologies to the ERP PM system. In this paper, a knowledge-based information system for the plant operation of steel making company has been proposed. This system, which is named as K-VRS(Knowledge-based Virtual Reality System), provides a connection between ERP plant maintenance module and knowledge-based engineering methodologies, and thus, enables network-based highly effective plant maintenance process. The developed system is expected to play a great role for more efficient and safer plant maintenance.

Structural Health Monitoring (SHM) has been attracting numerous research efforts around the world because it targets at monitoring structural conditions and performance to prevent catastrophic failure, and to provide quantitative data for engineers and infrastructure owners to design a reliable and economical asset management strategy. In the past decade, with supports from Australian Research Council (ARC), Cooperative Research Center for Infrastructure and Engineering Asset Management (CIEAM), CSIRO and industry partners, intensive research works have been conducted in the School of Civil, Environmental and Mining Engineering, University of Western Australia and Centre for Infrastructural Monitoring and Protection, Curtin University on various techniques of SHM. The researches include the development of hardware, software and various algorithms, such as various signal processing techniques for operational modal analysis, modal analysis toolbox, non-model based methods for assessing the shear connection in composite bridges and identifying the free spanning and supports conditions of pipelines, vibration based structural damage identification and model updating approaches considering uncertainty and noise effects, structural identification under moving loads, guided wave propagation technique for detecting debonding damage, and relative displacement sensors for SHM in composite and steel truss bridges. This paper aims at summarizing and reviewing the recent research advances on SHM of civil infrastructure in Western Australia.

A web-based Computer-Aided Engineering (CAE) supporting system is connected with a Product Data Management (PDM) system for Small and Medium Enterprises (SMEs) suffering from the lack of building hardware, software and related experts. An analysis of current business models and worksite requirements provides an improved process model and data to be shared between the PDM system and the CAE supporting system. Since all engineering tasks such as geometric modeling, mesh generation, static stress and modal analysis, and fatigue durability analysis are automated in the CAE supporting system, the user in charge of the CAE have only to configure the concerned values of design variables and result data through the web page. The existing Change Management module of the PDM system is modified for seamless data exchange, i.e. sending the Engineering Change Order (ECO) data to the CAE supporting system and receiving the CAE result data bark. The hi-directional data transfers between the PDM system and the CAE supporting system is made possible by adaptors bused on the Simple Object Access Protocol (SOAP). The current approach will be very helpful for SMEs that only have the PDM system and have no adequate infrastructure for CAE.

The various services applied internet have been provided by the rapid development of wireless networks and providing multimedia contents are also increasing. It is caused a number of problems such as increasing of network traffic rapidly. P2P technique is gaining popularity for solving these problems. In particular, P2P technique in a wireless network environment has gained much popularity. Among them, MANET-based P2P techniques has been studied actively. It is not easy to be applied the existing technique as it is due to the dynamic topology and low bandwidth by moving nodes in MANET that is consisted of only mobile nodes. In this paper, we proposed sharing group construction technique for providing a stable connection between mobile nodes and reducing the load of network traffic and overhead of sharing group reconfiguration in order to improve data transmission performance between mobile nodes. The sharing group member nodes applied virtual sharing group generation technique with neighboring nodes of 1-hop distance in order to reduce traffic for file sharing. We performed comparative experiments with DHT technique to evaluate the performance of the proposed technique in this paper and the excellent performance is confirmed through experiments.
