The purpose of this study is to probe into the influence mechanism of financial opening onto industrial restructuring from the prism of financial development and examine the role of the credit market, capital market and currency market in transmitting the impact of financial opening onto industrial restructuring in both developed countries and developing countries.

In the theoretical model, the indicator of financial opening was introduced in Cobb–Douglas production function formula. Using constant elasticity of substitution utility function, based on Engel’s law, the optimal industrial structure in the economy was concluded. For the empirical analysis, data was collected from 36 developed countries and 34 developing countries during the period 2000 to 2019. Multiple mediator models with bootstrap techniques were used to identify the linkage between financial opening, financial development and industrial restructuring.

First, there is a U-shaped relationship between financial opening and industrial restructuring. Second, financial development plays a mediating role in transmitting the effects of financial opening onto industrial restructuring mainly through the credit market at the global level. Third, developed countries are in a trend of “reindustrialization,” while developing countries show a trend of “premature deindustrialization.” Moreover, for developed countries, the capital market leads to reindustrialization, while the credit market and currency market contribute to deindustrialization. For developing countries, the capital market and credit market lead to deindustrialization, while the currency market contributes to industrialization.

Unlike most previous researches, this paper focuses on examining three-variable relationship between financial opening, financial development and domestic industrial restructuring. Against the backdrop of the pandemic, monetary policy shifts of developed economies have led to an increase in cross-border capital flows, which will lead to the increasing risks for international financial markets and the reallocation of the global value chain. It is of great significance to clarify the linkage between these three variables in the face of a volatile international financial environment.

Cold-formed steel has been used extensively as secondary elements such as purlins and girts in building frames. Purlin is critical to the structure of the roof because it supports the weight of the roof deck and aids to make the entire roof structure more rigid. Furthermore, cold-formed steel purlin is a replacement for wood purlin because steel purlins are light weight and more economical. Hence, the purpose of this study to investigate the effect of opening due to torsion behaviour.

This analysis used cold-formed steel hat purlin with and without openings (WOs) under different opening shape, location and spacing by using finite element LUSAS software.

The finite element results showed that purlin with openings had higher angle of rotation than section WO, with a percentage difference of not more than 6%. When the opening was located at mid-span, the angle of rotation reduced. Angle of rotation increased when the opening spacing increased. Number of openings also affected the torsional behaviour of the purlin. Five opening shapes, which were circle, diamond, C-hexagon, square and elongated circle, were studied. Among all the shapes, purlin with diamond opening was more resistance to torsion.

The use of cold-formed steel section with web openings (rectangular or circular) is a practical solution when it is required to pass service ducts through the structural member. However, the presence of opening gives minor effect on the structural behaviour of cold-formed steel hat purlin.

Tapered steel sections are widely used in house building design due to their structural efficiency and aesthetic appearance. Due to the practical usage of web tapering specifications in the metal building industry, fabrication and material expenses are analyzed to achieve geometric and economic productivity. The purpose of this study is to investigate the effectiveness of utilizing web profiles with openings in reducing the weight of steel beams.

In this paper, the nonlinear analysis of the bending behavior of a tapered steel section with an opening was studied by finite element analysis. The results were then compared with those of the tapered steel section without an opening in terms of displacement and yield moment.

The bending capacity of a tapered steel section was analyzed using finite element analysis. Results showed that the tapered steel section without openings had a higher bending capacity compared to the section with various sizes of web openings. The results also showed that decreasing the number of openings would increase the bending capacity, whereas increasing the size of the opening would decrease it. The difference in the yield moment between the tapered steel section with and without openings was only 15.818%. A total of 60 nonlinear analyses were conducted to investigate the effect of the number and size of web openings, flange thickness and web thickness on the bending behavior. However, this study showed that web opening with octagon shape and 0.6D size of web opening, where D is the depth of section, showed the best section in terms of yield moment and volume reduction compared to other opening size and shape.

It is also found that tapered steel section has better moment resistance in thicker flange and web. The study is valuable for engineers and designers who work with steel structures and need to optimize the performance of tapered steel sections with web openings.

The purpose of this paper is to understand consumer perspectives and trade-offs on packaging convenience attributes of various food and drink packages vs increased cost.

The research utilized structured interviews to collect pertinent data. Personal interviews were conducted at major supermarkets within Bangkok and the vicinity. During data collection, 600 interviews were concluded. Target groups were composed of those who are major shoppers of particular food and drink products. In total, three packages for food products and two packages for drink products were selected for the study, including snack pouches, tuna cans, ready-to-eat plastic trays, laminated juice cartons, and plastic bottles for drinking water. Packaging attributes that were taken into consideration were structure, body style, opening mechanism, reseal features, and tamper-evident characteristics. Part worth analysis and importance level of increased price factors compared with packaging attributes were discussed. Conjoint analysis was used for importance score calculation and data analysis.

The most important packaging attributes for all packages were the opening characteristics. Tamper-evident characteristics were also perceived as very important for drinking water bottles. However, for all packages, the importance score level for the price factor accounted for only 10-19 percent. As a result, opening characteristics of the packages seemed to influence consumer purchasing decisions for food and drink products; most consumers were happy to trade-off on a slight increase in price for additional convenience or tamper-evident features of a package.

The findings of this study can be used in making strategic packaging decisions to improve customer satisfaction and increase sales.

Due to the enormous increase in economic development, structural steel material gives an advantage for the construction of stadiums, factories, bridges and cities building design. The purpose of this study is to investigate the behaviour of bending, buckling and torsion for I-beam steel section with and without web opening using non-linear finite element analysis.

The control model was simulated via LUSAS software with the four main parameters which included opening size, layout, shape and orientation. The analysis used a constant beam span which is 3.5 m while the edge distance from the centre of the opening to the edge of the beam is kept constant at 250 mm at each end.

The analysis results show that the optimum opening size obtained is 0.65 D while optimum layout of opening is Layout 1 with nine web openings. Under bending behaviour, steel section with octagon shapes of web opening shows the highest yield load, yield moment and thus highest structural efficiency as compared to other shapes of openings. Besides, square shape of web opening has the highest structural efficiency under buckling behaviour. The lower buckling load and buckling moment contribute to the higher structural efficiency.

Further, the square web opening with counter clockwise has the highest structural efficiency under torsion behaviour.

Due to economic development, tapered members are commonly applied in steel frames, namely, industrial halls, warehouses, exhibition centres, etc. In the design of cantilever steel beam structures in cities building design, tapering is introduced at the web profile to achieve utmost economy and suit the bending moment distributions. The cross-sectional shape of the beam is varied linearly to the moment gradient to achieve the target of higher efficiency with lower cost.

The shear deformation pattern and efficiency of the tapered steel section with perforation were investigated using finite element analysis. In addition, I-beam with web opening is studied numerically via LUSAS software for different parameters of tapering ratio, perforation shape and perforation size and perforation layout.

The highest contributing parameters for the highest shear buckling capacity and efficiency of the section were due to the small opening size and tapering ratio. Whilst the variation of perforation layout and spacing give a major effect on the shear strength and efficiency of the tapered steel section with perforation. Besides that, the highest efficiency model is found when the section is designed with 0.4 D diamond perforation in Layout 3 under a tapering ratio of 0.3. The critical shear buckling load and efficiency is reduced 14.39% and 13.91%, respectively, when perforations are added onto the tapered steel sections.

The tapered steel section with perforation has lower critical shear buckling load and efficiency compared to the tapered section without perforation but obtains a higher critical shear buckling load and efficiency compared to the uniform section without perforation.

Recently, this steel section has found increasing popularity in residential, industrial and commercial buildings with their high load-carrying capacity due to the nature of high strength to weight ratio properties. However, the rise on the price of steel section should be more emphasized; therefore, the optimization in steel section design is needed to overcome the issue of material cost. As such, tapered steel sections save on material use, while the introduction of web openings allows the placement of mechanical and electrical services, plumbing and also aesthetic design considerations.

The purpose of this study is to investigate the lateral torsional buckling behavior of a tapered steel section with an ellipse-shaped opening by analyzing its structural parameters. To achieve this, the finite element analysis (FEA) of the section is modeled using LUSAS software, which allows for a detailed analysis of the section's behavior under varying loads and conditions. It involves the variation in web opening size, opening layout, opening rotation angle and the tapering ratio. Eigenvalue buckling analysis is adopted to know the parametric effects of each 108 model. The size of opening varies from 0.2 to 0.5 d of the total depth where the opening located. There are three type of layouts applied in this study, which are the layouts A, B and C. There are three types of rotation angles for the ellipse-shaped opening, including the non-rotated vertical opening and two additional types formed by rotating the opening 45 degrees clockwise and counterclockwise around the center-point of the ellipse. A fixed-free boundary condition was applied, resulting in a simulation of a cantilever beam. The models are fixed at one end with a larger depth, and free at the other end with a smaller depth. Loading condition is an application of 10 kN/m uniform distributed load in the direction of gravity along the mid-span of the top flange.

It is observed that the model 82 with Layout A, tapering ratio 0.3, opening size 0.5 d and opening rotated in 45 degree anti-clockwise direction results in the highest structural efficiency among the 108 models. Therefore, the buckling moment of model 82 is 1,013.08 kNm with structural efficiency of 481.26, which shows an increase of 3.17% compared to the controlled model.

The FEA results shows a significant increase in ductility and stiffness of the tapered steel section with elipse shape opening and consequently changes in the behaviour of yield point.

This paper seeks to explore how Indian buying firms practise an open book (OB) policy in supplier relationships in three industries, i.e. the vehicle industry, the construction industry and the information technology industry. It also aims to study determinants of open book practices.

Application of the OB policy is operationalised as the nature of open book practices, the extent and stage of data disclosed, the form of data disclosed, the direction of data disclosed, the attitude towards cost data disclosed, and the purpose and conditions of data disclosed. Determinants of the open book policy comprise characteristics of the exchange, the product, the buyer, the supplier and the supply market. Qualitative data were collected in the form of 22 interviews with representatives of three buying organisations and several of their suppliers in order to build three case studies.

The results suggest that the OB policy is used by buyers for diverse purposes ranging from strategic to operational, for example value engineering at the product development stage, to ensure supplier margins, for self improvements and cost reductions, and country entry decisions. Similarly, the data shared ranged from narrow to wide in scope and scale. Suppliers' attitudes ranged from fairly neutral to very negative towards open books. Power asymmetries, the number of alternative suppliers, product performance characteristics and value, incentives offered, and buyer efforts were found to influence OB practices.

Experiences gained from employing an OB policy in vehicle manufacturing suggests that firms in other industries can better leverage the use of open books for joint problem solving, equitable profit sharing and supplier selection.

The paper highlights that an OB policy can have broader applicability than recognised by many past studies and indicates that it can serve purposes of strategic decision‐making. It can also be an integrated part of a buyer's risk reduction strategy. Further, the study provides specific recommendations for Indian companies with regard to the application of an open book policy.

This paper aims to present the sustainable performance criteria for 3D printing practices, while reporting the primarily computations and lab experimentations. The potential advantages for integrating three-dimensional (3D) printing into house construction are significant in Construction Industry 4.0; these include the capacity for mass customisation of designs and parameters for functional and aesthetic purposes, reduction in construction waste from highly precise material placement and the use of recycled waste products in layer deposition materials. With the ultimate goal of improving construction efficiency and decreasing building costs, applying Strand7 Finite Element Analysis software, a numerical model was designed specifically for 3D printing in a cement mix incorporated with recycled waste product high-density polyethylene (HDPE) and found that construction of an arched truss-like roof was structurally feasible without the need for steel reinforcements.

The research method consists of three key steps: design a prototype of possible structural layouts for the 3DSBP, create 24 laboratory samples using a brittle material to identify operation challenges and analyse the correlation between time and scale size and synthesising the numerical analysis and laboratory observations to develop the evaluation criteria for 3DSBP products. The selected house consists of layouts that resemble existing house such as living room, bed rooms and garages.

Some criteria for sustainable construction using 3DP were developed. The Strand7 model results suggested that under the different load combinations as stated in AS1700, the maximum tensile stress experienced is 1.70 MPa and maximum compressive stress experienced is 3.06 MPa. The cement mix of the house is incorporated with rHDPE, which result in a tensile strength of 3 MPa and compressive strength of 26 MPa. That means the house is structurally feasible without the help of any reinforcements. Investigations had also been performed on comparing a flat and arch and found the maximum tensile stress within a flat roof would cause the concrete to fail. Whereas an arch roof had reduced the maximum tensile stress to an acceptable range for concrete to withstand loadings. Currently, there are a few 3D printing techniques that can be adopted for this purpose, and more advanced technology in the future could eliminate the current limitation on 3D printing and bring forth this idea as a common practice in house construction.

This study provides some novel criteria for evaluating a 3D printing performance and discusses challenges of 3D utilisation from design and managerial perspectives. The criteria are relied on maximum utility and minimum impact pillars which can be used by scholars and practitioners to measure their performance. The criteria and the results of the computation and experimentation can be considered as critical benchmarks for future practices.

The purpose of this study is to analyze heat transfer for solid–liquid phase change in two inclined cavities assisted with open cell and closed cell porous structures for enhancement of heat transfer and compare them.

The heat transfer analysis is done numerically. The set of conservation equations for mass, momentum and energy for phase change material (PCM) and conduction heat transfer equation for metal frame are solved. Furthermore, temperature and solid–liquid fraction distributions for a cavity filled only with PCM are also obtained for comparison. The porosity is 0.9 for both porous structures. Rayleigh number and inclination angle change from 1 to 10⁸, and from −90° to 90°, respectively.

The present study reveals that the use of closed cell structures not only can make phase change faster than open cell structure (except for Ra = 10⁸ and = 90°) but also provide more stable process. The use of a closed cell porous structure in a cavity with PCM can reduce melting period up to 55% more than a cavity with an open cell porous structure. The rate of this additional enhancement depends on Rayleigh number and inclination angle.

To the best of the authors’ knowledge, this is the first time that the comparison between closed cell and open cell porous structures for heat transfer enhancement in a solid/liquid phase change process is reported. Authors believe that the present study will lead more attentions on the use of closed cell porous structures.
