Structural Health Monitoring (SHM) is used to provide reliable information about the structure's integrity in near realtime following extreme incidents such as earthquakes, considering the inevitable aging and degradation that occurs in operating environments. This paper experimentally investigates an integrated wireless sensor network (Wi-SN) based monitoring technique for damage detection in concrete structures. An effective SHM technique can be used to detect potential structural damage based on post-earthquake data. Two novel methods are proposed for damage detection in reinforced concrete (RC) building structures including: (i) Jerk Energy Method (JEM), which is based on time-domain analysis, and (ii) Modal Contributing Parameter (MCP), which is based on frequency-domain analysis. Wireless accelerometer sensors are installed at each story level to monitor the dynamic responses from the building structure. Prior knowledge of the initial state (immediately after construction) of the structure is not required in these methods. Proposed methods only use responses recorded during ambient vibration state (i.e., operational state) to estimate the damage index. Herein, the experimental studies serve as an illustration of the procedures. In particular, (i) a 3-story shear-type steel frame model is analyzed for several damage scenarios and (ii) 2-story RC scaled down (at 1/6th) building models, simulated and verified under experimental tests on a shaking table. As a result, in addition to the usual benefits like system adaptability, and cost-effectiveness, the proposed sensing system does not require a cluster of sensors. The spatial information in the real-time recorded data is used in global damage identification stage of SHM. Whereas in next stage of SHM, the damage is detected at the story level. Experimental results also show the efficiency and superior performance of the proposed measuring techniques.

Purpose Recently, hyper-realistic virtual influencers have received much attention in the field of corporate marketing. However, there is a lack of research that suggests specific processes affecting behavioral intentions through trust and attachment between virtual influencers and consumers. In addition, previous studies have failed to consider the characteristics of hyper-realistic virtual influencers. Therefore, this study investigates the effects of trust and attachment to hyper-realistic virtual influencers on consumers' behavioral intentions based on the trust-building model. Design/methodology/approach Based on the previous research, seven antecedent factors for trust-building were derived: Reality, Attractiveness, Awareness, Interactivity, Professionalism, Social Presence, and Predictability. Next, the survey was conducted on Chinese people who had experienced interacting with hyper-realistic virtual influencers on social network services within the last 3 months at the time of data collection. A total of 326 respondents were used for the final analysis and hypotheses were tested using a structural equation model technique. Findings The results of this study are as follows. First, this study confirmed that reality, attractiveness, awareness, social presence, and predictability as antecedent factors for trust-building of hyper-realistic virtual influencers have a positive effect on trust. Second, this study confirmed that trust in hyper-realistic virtual influencers has a significant positive effect on attachment. Lastly, this study confirmed that trust and attachment to the hyper-realistic virtual influencer significantly and positively affect relationship retention and purchase intentions.

Focus on climate change and extreme weather conditions has received considerable attention in recent years. Civil engineers are now focusing on designing buildings that are more eco-friendly in the face of climate change. This paper describes the research conducted to assess the impact of future climate change on energy usage and carbon emissions in a typical supermarket at multiple locations across the UK. Locations that were included in the study were London, Manchester, and Southampton. These three cities were compared against their building performance based on their respective climatic conditions. Based on the UK Climatic Projections (UKCP09), a series of energy modelling simulations which were provided by the Chartered Institute of Building Service Engineers (CIBSE) were conducted on future weather years for this investigation. This investigation ascertains and quantifies the annual energy consumption, carbon emissions, cooling, and heating demand of the selected supermarkets at the three locations under various climatic projections and emission scenarios, which further validates annual temperature rise as a result of climatic variation. The data showed a trend of increasing variations across the UK as one moves southwards, with London and Southampton at the higher side of the spectrum followed by Manchester which has the least variability amongst these three cities. This is the first study which investigates impact of the climate change on the UK supermarkets across different regions by using the real case scenarios.

The purpose of this study is to develop a model for renewing old public buildings by incorporating mobility technology into them for the convenience of citizens' transportation and the enhancement of public services, and to propose support measures to improve the direction of implementation. The main contents and results of this study are as follows. First, the renewal target site was selected based on the technical considerations and evaluation criteria required for the renewal of public buildings incorporating mobility technology, and the construction was planned by analyzing the necessary mobility technology based on the size, area, and district unit plan of the selected target site. Second, the expected cost was calculated based on the construction plan and the financial support plan necessary for reflecting mobility technology was proposed. Third, the improvement plan of the building code system required for the development of public building renewal incorporating mobility technology was proposed. This study had limitations in that it could not reflect detailed construction costs due to the lack of design standards and experience, and it was difficult to identify specific problems due to the lack of specific operation methods and implementation cases.

More emphasis has recently been put on the strategic application of IT, the linkage and integration between information system, and business process for value increase of a company's business. Thus, it is high time to redefine the concept of IT governance in order to effectively manage various IT services and assets. However, less attention has been paid to the practical study of domestic firms, compared to in the academic and industrial level. In this study, the current situation of IT governance setup and various factors for future development will be examined by a case study to explore activities, types, and determinants of decision making process that companies are currently conducting regarding IT governance. For the purpose of comparative analysis, two large enterprises were chosen with similar size of sales and high investment rate for IT within the same industry, and in-depth analysis was conducted based on the interviews of the concerned parties and in-house materials, from the perspective of structure, process, and relational mechanism. By the case study on IT governance of company 'A' and 'B', decision making mechanism and factors will be analyzed, which will indicate detailed characteristics of each decision-making field and its components for general application. By doing so, it is expected to be used as reference in building IT governance that fits the environment of a firm in the future.

IT consulting is becoming a norm rather than exception in this age of smart work and information revolution. As IT consulting is one of the knowledge intensive services requiring high credence on both sides, maintaining a good trustful relationship is critical in sustenance of strategic partnership between business firms and IT service firms. Trust is known to be one of the salient constructs in service relationships. In this study, building from the social psychology literature, trust is conceptualized as two dimensions : cognitive and affective trust. Using two dimensions of trust as mediators, a research model is constructed for IT consulting specific context : relationship continuance intention as the dependent construct while expertise, service performance, reputation, relationship satisfaction and value similarity as antecedents of cognitive and affective trust. 145 data points were collected through a survey of IT service client project managers retrospectively asking their experience with IT consultants. Findings suggest that cognitive trust is associated with perceived level of expertise and service performance while affective trust with relationship satisfaction and value similarity, respectively. Interestingly, the paths from reputation are found to be statistically insignificant towards both dimensions of trust, indicating IT service context would be more practically outcome oriented than any other professional service context. Also, cognitive trust seems to maintain stronger influence on relationship continuance intention as anticipated. Implications and limitations are discussed at the end.

Land price can be affected by convenience or psychological repulsion like PIMFY (Please In My Front Yard) or NIMBY (Not In My Back Yard) for various facilities. Services related to public establishment, welfare, medical attention, and amenities in rural areas are comparatively poorer than those in urban areas. The purpose of this study is to estimate the implications of the accessibility to community facilities in rural areas for land prices using a hedonic price model. The accessibility to facilities is estimated by real road distances and the land prices are applied for four types of land usages: field, rice paddy, building lots, and village halls. Community facilities are classified from public and community services view: education, safety, culture, transport, environment, health care, and finance. The results show that the accessibility to health care and transport can positively affect land prices and the accessibility to environment (waste facilities and junkyard) and unpleasant services (funeral hall and charnel house) can negatively affect land prices. Especially, the accessibility to hospital is the most positive influential factor for all types of land usages.

In Korea, Crowds, as well as more complex and larger structures, have been caused more victims in the event of fire. In that situation, EMSS should have done triage the patients according to their severity in the field, treat with standard guidelines as like advanced burn life support and transfer to appropriate facility. But in many cases, they didn't practice like that. The purpose of this study is to give basic data for proper emergency medical services by analysing EMSS of large scaled fire in Korea and suggesting some improvement methods. The improvment methods are like this ; First, developing of protocols about burn patient is needed for EMT and dispatcher. Second, Legal approval for advanced treatment is needed for EMT. Third, Fire-helicoptors are needed in Daejeon and Jeju. And Emergency Medical Helicoptors are needed in EMSS. Forth, more advanced emergency medical centers of burn must be established. Sixth, more pocket-mask and burn sheet are needed for 119 rescuer. Finally, building owners must change inflammable materials as non-inflammable materials and educate fire-prevention and first-aid to employees.
