Authors: Yeh Jui-Feng , Huang Yu-Jui , Huang Kao-Pin 
Published: August 2017

Purpose
This study aims to provide an ontology based Baysian network for clinical specialty supporting. As a knowledge base, ontology plays an essential role in domain applications especially in expert systems. Interactive question answering systems are suitable for personal domain consulting and recommended for real-time usage. Clinical specialty supporting for dispatching patients can assist hospitals to locate desired treatment departments for individuals relevant to their syndromes and disease efficiently and effectively. By referring to interactive question answering systems, individuals can understand how to alleviate time and medical resource wasting according to recommendations from medical ontology-based systems.

Design/methodology/approach
This work presents an ontology based on clinical specialty supporting using an interactive question answering system to achieve this aim. The ontology incorporates close temporal associations between words in input query to represent word co-occurrence relationships in concept space. The patterns defined in lexicon chain mechanism are further extracted from the query words to infer related concepts for treatment departments to retrieve information.

Findings
The precision and recall rates are considered as the criteria for model optimization. Finally, the inference-based interactive question answering system using natural language interface is adopted for clinical specialty supporting, and indicates its superiority in information retrieval over traditional approaches.

Originality/value
From the observed experimental results, we find the proposed method is useful in practice especially in treatment department decision supporting using metrics precision and recall rates. The interactive interface using natural language dialogue attracts the users’ attention and obtains a good score in mean opinion score measure.
Study of a harmonic drive with involute profile flexspline by two-dimensional finite element analysis
Authors: Chen Yi-Cheng , Cheng Yun-Hao , Tseng Jui-Tang , Hsieh Kun-Ju 
Published: August 2017

Purpose
This paper aims to present simulation results of a harmonic drive (HD) with involute flexspline (FS) profiles based on two-dimensional (2-D) finite element analysis (FEA).

Design/methodology/approach
First, the mathematical model of the FS with involute tooth profile was developed using a straight-edge rack cutter based on the theory of gearing. Then the engaging circular spline (CS) with conjugate tooth profile of FS was derived based on the enveloping theory and theory of gearing. Additionally, a mesh generation program was developed to discretize the FS based on the mathematical model. An elliptical wave generator (WG) was inserted into the FS, and a torque was applied to drive the FS meshing with the CS. The WG and the CS were both assumed to be rigid in the finite element model.

Findings
Finally, a 2-D FEA was conducted to explore the stress distribution on the FS, the engagement movement of the FS, the torsional stiffness and the engaged area of teeth of the HD under various conditions. Moreover, this research also studied the effect of changing pressure angle of the involute FS on the performance of the HD.

Research limitations/implications
The simulation model and methodology presented in this paper paved the way for further investigation and optimization of the HD with involute tooth profile FS and conjugate CS.

Originality/value
The simulation model of HD is established on conjugate shape based on the theory of gearing and an automatic mesh generation program is developed to generate the finite element model. The characteristics of the HD can thus be simulated according to the developed model.
Spoken dialogue BIM systems – an application of big data in construction
Authors: Motawa Ibrahim 
Published: August 2017

Purpose
With the rapid development in the internet technologies, the applications of big data in construction have seen considerable attention. Currently, there are many input/output modes of capturing construction knowledge related to all construction stages. On the other hand, building information modelling (BIM) systems have been developed to help in storing various structured data of buildings. However, these systems cannot fully capture the knowledge and unstructured data used in the operation of building systems in a usable format that uses the intelligent capabilities of BIM systems. Therefore, this research aims to adopt the concept of big data and develop a spoken dialogue BIM system to capture buildings operation knowledge, particularly for building maintenance and refurbishment.

Design/methodology/approach
The proposed system integrates cloud-based spoken dialogue system and case-based reasoning BIM system.

Findings
The system acts as an interactive expert agent that seeks answers from the user for questions specific to building maintenance problems and helps searching for solutions from previously stored knowledge cases. The practices of monitoring and maintaining buildings performance can be more efficient by the retrieval of relevant solutions from the captured knowledge to new problems when maintaining buildings components. The developed system enables easier capture and search for solutions to new problems with a more comprehensive retrieval of information.

Originality/value
Capturing multi-modes data into BIM systems using the cloud-based spoken dialogue systems will help construction teams use the high volume of data generated over building lifecycle and search for the most suitable solutions for maintenance problems. This new area of research also contributes to the current BIM systems by advancing their capabilities to instantly capture and retrieve knowledge of operations instead of only information.
Building Information Modelling and vertical farming
Authors: Khan Rana Raheel Afzal , Ahmed Vian 
Published: August 2017

Purpose
The UN statistics show that the world’s population is expected to be nine billion by the 2050. As a result, the food production must also be raised to 70 per cent or more. Vertical farming (VF) is an innovative and alternative approach to meet the challenges; however, its management will also be a challenge. This paper, therefore, shares the understanding of future food challenges and Building Information Modelling (BIM) and its application to manage the facility.

Design/methodology/approach
A conceptual digital prototype of a VF is developed in a BIM environment using design science. First, the data are collected from literature review and then analysed and simulated for optimum conditions in a BIM-enabled digital prototype.

Findings
The results showed that BIM to manage a VF has not been researched or explored yet. However, BIM has proven its numerous benefits to the architecture, engineering and construction and facility management industries, and it is a powerful solution to design and manage VF to solve future food production problems.

Originality/value
There is a very limited research on VF in the literature, and BIM for VF is also not discussed or researched yet. The originality and value of this research stems from both expanding BIM horizons and designing and managing VF.
Effect of rounded corners on two degree of freedom naturally oscillating square cylinder
Authors: Miran Sajjad , Sohn Chang Hyun 
Published: August 2017

Purpose
The paper aims to study the influence of rounded corners on the flow-induced oscillation of a square cylinder that is free to oscillate in two degrees of freedom.

Design/methodology/approach
The finite volume code in conjunction with the moving mesh scheme was implemented via a user-defined function to carry out the computations in two dimensions. The Reynolds number (Re) chosen for the present study is fixed at 100, and the frequency ratio, Fr = fs/fn (where fs is the vortex shedding frequency and fn is the natural frequency of cylinder) is used as a varying parameter. The computational model was validated for flow past a stationary cylinder with R/D = 0 and 0.5, and the results showed good agreement with the literature.

Findings
The aerodynamic characteristics, amplitude response, trajectories of cylinder motion and vortex shedding modes are obtained by conducting a series of simulations under different frequency ratios of the cylinder. It was found that the minimum transverse amplitude, drag force and lift force obtained for a naturally oscillating square cylinder are quite different when compared with a stationary and forced oscillating cylinder, where the maximum drag and lift forces were observed for a square cylinder and a minimum around R/D = 0.2 was observed.

Originality/value
The present work identified the significant effect of the varying frequency ratio and R/D on the VIV modes of the cylinder. It was observed that the cylinder wake exhibits the (2S) vortex shedding mode for R/D = 0 to 0.2 at all Fr, whereas the C (2S) mode appeared for R/D > 0.2 at Fr = 1.1.
Free convection in a square cavity filled with a Casson fluid under the effects of thermal radiation and viscous dissipation
Authors: Pop Ioan , Sheremet Mikhail 
Published: August 2017

Purpose
The main purpose of this numerical work is to study free convection of Casson fluid in a square differentially heated cavity taking into account the effects of thermal radiation and viscous dissipation.

Design/methodology/approach
The cavity is heated from the left vertical wall and cooled from the right vertical wall while horizontal walls are insulated. The governing partial differential equations invoking Rosseland approximation for thermal radiation with corresponding boundary conditions have been solved by finite difference method of the second-order accuracy using dimensionless variables stream function, vorticity and temperature. The governing parameters are Rayleigh number (Ra = 105), Prandtl number (Pr = 0.1, 0.7, 7.0), Casson parameter (γ = 0.1-5.0), radiation parameter (Rd = 0-10), Eckert number (Ec = 0-1.0).

Findings
It is found that an increase in Casson parameter leads to the heat transfer enhancement and fluid flow intensification. While a growth of Eckert number illustrates the heat transfer suppression.

Originality/value
The originality of this work is to analyze for the first-time natural convective fluid flow and heat transfer of a Casson fluid within a differentially heated square cavity under the effects of thermal radiation and viscous dissipation. The results would benefit scientists and engineers to become familiar with the flow behavior of such non-Newtonian fluids, and the way to predict the properties of this flow for possibility of using this specific fluid in various engineering and industrial processes, such as chyme movement in intestine, blood flows, lubrication processes with grease and heavy oils, glass blowing, electronic chips, food stuff, slurries, etc.
Numerical study on the effect of EHD flow on mass transfer of gas mixtures
Authors: Ma Qiang , Chen Zhenqian 
Published: August 2017

PurposeThe paper aims to discuss the mass transfer of gas mixtures under the influence of electrohydrodynamic (EHD) flow induced by direct current (DC) corona discharge of wire-to-plane electrode, using a coupled numerical model.Design/methodology/approachA coupled numerical method is developed in this paper. Lattice Boltzmann model of binary gas mixtures coupled with the Coulomb force as an external force is introduced to predict the gas flow and species transport affected by EHD flow. Meanwhile, the distributions of electric field and space charge density during DC corona discharge are obtained using the finite difference method and the method of characteristics.FindingsThe numerical results of mass transfer effected by EHD flow reveal that the high electric field intensity is observed near the surface of corona wire, which causes the higher Coulomb force to form the EHD flow pattern of anticlockwise vortex. The EHD vortex flow plays a considerable role in the mass transport enhancement of gas species emit from the plane electrode, and the significant difference of the local Sherwood number is presented along the direction parallel to plane electrode. In addition, the enhance effectiveness with the different applied voltage is assessed, and the influencing mechanism of enhancement is investigated in this work.Originality/valueThe proposed numerical model will be useful in the study of mass transfer and fluid flow effected by EHD.
Natural convective heat transfer in the air-filled interstice between inclined concentric hemispheres
Authors: Alilat Nacim 
Published: August 2017

Purpose
The main purpose of this work is to quantify the convective heat transfer occurring between two inclined and concentric hemispheres.

Design/methodology/approach
The inner one is an electronic assembly generating a constant heat flux during operation. The outer hemisphere is maintained isothermal at cold temperature. The interstitial space is air-filled. The base of the equipment can be inclined with respect to the horizontal plane by an angle ranging from 0° (horizontal position with dome faced upwards) to 180° (horizontal position with dome faced downwards).

Findings
Nusselt–Rayleigh correlations are proposed for several configurations obtained by varying the generated power and the base inclination. The large resulting Rayleigh number ranging between 2.4 × 105 and 1.7 × 107 allows using these new and original correlations in various engineering fields, such as electronics in the present work. The calculations are realized by means of a 3D numerical approach based on the finite volume method.

Originality/value
The geometry and the thermal boundary conditions considered in the present survey are suitable for applications in many engineering areas.
Assessing servicescape of cruise tourism: the perception of Chinese tourists
Authors: Lyu Jiaying , Hu Liang , Hung Kam , Mao Zhenxing 
Published: August 2017

Purpose
This study aims to develop a comprehensive framework for assessing servicescape of cruise tourism and provides practical suggestions to improve the perception of Chinese tourists toward cruise servicescape.

Design/methodology/approach
A multistage mixed-method design was used in the sequence of in-depth interviews (n = 18), expert panel (n = 5), on-site survey (n = 317) and online survey (n = 300). Grounded theory, exploratory factor analysis and confirmatory factor analysis were used to assess cruise tourism servicescape.

Findings
The cruise tourism servicescape construct was identified with six dimensions: facilities and décor, natural scenery, onshore excursions, onboard entertainment, social interactions and dining services. These dimensions were in the order of importance, as perceived by Chinese tourists.

Practical implications
Cruise lines operating large ships can be more attractive to Chinese consumers than luxury cruise lines operating smaller vessels. Cruise operators can enhance perceived servicescape by integrating natural and built environments, such as air, sea and on-shore tours. Services provided by foreign crew members may serve as a strong selling point for Chinese tourists. Consumer-to-consumer activities may be introduced into the Chinese market. Cruise operators may also provide quality meal service in terms of variety, quality and flexibility.

Originality/value
Considering that minimal research has been conducted on cruise servicescape scale development, this study serves as the first empirical research effort in this regard. The findings also identify the specific needs of Chinese tourists, which is a fast-growing market in the cruise industry.
Heuristic evaluation of healthy menus: examining the effect of brand image congruity
Authors: Jeong Eunha , Jang SooCheong (Shawn) 
Published: August 2017

PurposeThis study aims to investigate how restaurant customers’ heuristic judgment, originating from their perceived level of congruity between restaurant brand image regarding healthfulness and healthy menu products, can affect their information processing in terms of their perceived nutritional information credibility and, furthermore, how these effects influence customers’ attitude toward the menu in terms of healthiness.Design/methodology/approachA Web-based survey was developed and distributed to randomly selected respondents in the USA, and in total, 320 responses were used for the data analyses. Structural equation modeling (SEM) was used to examine the relationship among three constructs: perceived brand–product congruity, perceived nutritional information credibility and nutrition attitude toward the healthy menu item being promoted. To assess the mediating role of perceived information credibility, an analytical procedure proposed by (Baron and Kenny 1986) was used. Finally, to investigate the moderating effect of the health involvement, multiple group analyses were executed.FindingsThe study results suggested that the synchronization between healthful brand image of the restaurant and the promoted menu item is important for ensuring customers’ perceptions of information credibility regarding the menu item healthiness and for eliciting customers’ positive nutrition attitudes toward the menu item. Also, positive nutrition attitudes toward a menu item can be increased by improving perceived information credibility. Depending on an individual’s level of health involvement, the relationships between the three proposed constructs vary.Originality/valueThis paper includes a theoretical model that explains customers’ heuristic evaluation of a healthy menu product by assessing the influence of brand image congruity in terms of healthy menu promotion.
Co-creation in hotel service innovation using smart phone apps: an empirical study
Authors: Sarmah Bijoylaxmi , Kamboj Shampy , Rahman Zillur 
Published: August 2017

Purpose
The purpose of this study is to extend and revise the basic technology-based service (TBS) adoption model in luxury hotels in India using smart phone apps, and to analyse the impact of the guests’ innovativeness, willingness to co-create, need for interaction and involvement on their adoption intention towards co-creatively developed new services.

Design/methodology/approach
Data were collected through online and field surveys from luxury hotel guests, resulting into 229 valid responses. A data analysis was done by applying the confirmatory factor analysis along with structure equation modelling.

Findings
The findings of this study indicate that both guests’ innovativeness and need for interaction with service staff significantly affect their involvement. A guest’s willingness to co-create acts as a partial mediator between his/her innovativeness and intention to adopt co-creatively developed new services.

Research limitations/implications
Use of smart phone apps by hotel guests to co-create new services and their intentions to adopt such services have been examined in the context of luxury hotels in India only and thereby limits generalization of results to other industry and country contexts.

Practical implications
The findings of this study would look to guide policy planners and hotel managers for implementing technology application in the co-creative hotel service innovation.

Originality/value
The need for interaction and customer involvement have been added as two supportive variables to the basic TBS model to analyse the adoption intention of luxury hotel guests. This is a new addition to existing literature, as majority of empirical studies in this field are from industries other than hospitality and with differing contexts.

Published: August 2017

Purpose
Hospital responsiveness to the patient expectations of non-medical aspect of care can lead to patient satisfaction. The purpose of this paper is to investigate the relationship between the eight dimensions of responsiveness and overall patient satisfaction in public and private hospitals in Tehran, Iran.

Design/methodology/approach
This cross-sectional study was conducted in 2015. In all, 500 patients were selected by the convenient sampling method from two public and three private hospitals. All data were collected using a valid and reliable questionnaire consisted of 32 items to assess the responsiveness of hospitals across eight dimensions and four items to assess the level of overall patient satisfaction. Data analysis was performed using descriptive statistics and multivariate regression was performed by SPSS 18.

Findings
The mean score of hospital responsiveness and patient satisfaction was 3.48±0.69 and 3.54±0.97 out of 5, respectively. Based on the regression analysis, around 65 percent of the variance in overall satisfaction can be explained by dimensions of responsiveness. Seven independent variables had a positive impact on patient satisfaction; the quality of basic amenities and respect for human dignity were the most powerful factors influencing overall patient satisfaction.

Originality/value
Hospital responsiveness had a strong effect on overall patient satisfaction. Health care facilities should consider including efforts to responsiveness improvement in their strategic plans. It is recommended that patients should be involved in their treatment processes and have the right to choose their physician.
