Abstract:
Roughing operation is used to improve the adhesive properties of footwear upper to footwear bottom polyurethane compositions in the manufacture of special purpose footwear with an upper made of genuine leather by the injection molding method of attachment. Roughing operation is an operation of coating removal and partial removal of the front layer from the protracted edge of footwear upper workpiece. This operation has a disadvantage, it often causes technological defects. A method for increasing the adhesive properties of genuine leather special purpose footwear upper workpiece with a front layer by means of non-equilibrium low temperature plasma modification and technological scheme that allows this operation to be integrated into the production process are considered in the article.

Abstract:
The inability to take into account the type of base material (floor, pavement, soil), as well as the inability to take into account the variable friction conditions – load, intermediary medium (water, loose abrasive, sand or other soil particles), sliding velocity, and ambient temperature – is a significant limitation the use of friction methods and devices used so far in the footwear industry to precisely anticipate the behavior of the bottom materials in the actual operating conditions of the footwear. These limitations prompted the authors to adapt a tribological tester for this purpose, used in the area of construction and operation of machines and material engineering. A research methodology was developed and, in order to verify it, measurements of the coefficient of friction and wear of polyurethane used for shoe soles in combination with a raw and varnished wooden substrate were carried out. The obtained test results are characterized by diversity, which proves the high research resolution of the developed method. It allows determining the coefficient of friction of associations influencing the slip of the footwear and the wear and tear that determines the length of use of the footwear.

Abstract:
The number of partial-foot amputations performed is increasing, and many recommendations have been made regarding the use of prostheses and footwear designed to prevent higher-level amputations in this population. The present study investigated the use of prostheses and shoe inserts and the types of footwear worn by partial-foot amputees in the inner city to determine whether previous recommendations are being followed as well as whether new prosthetic styles are being used. The study surveyed 110 patients (73 men and 37 women) with a mean age of 58.6 years (range, 21 to 86 years) with partial-foot amputations of all levels. The results showed that about one-half of all patients wore a shoe-insert orthosis. Although 54% wore some form of special footwear to accommodate and protect the residual foot, no patient in this study wore a shoe with a rocker-bottom sole. Only one patient with a transmetatarsal amputation used a brace and only one patient in the entire study wore a modern cosmetic foot prosthesis. (J Am Podiatr Med Assoc 91(1): 34-49, 2001)

Abstract:
Human footprints and footwear traces were one of the first well-studied forensic objects of examination. This is due to the fact that these traces are most often found at the scene of the incident, as well as by the fact that they contain most valuable and significant information needed for criminal investigation. Forensic examination of footprints and footwear traces of a person are among the most common trace evidence examinations encountered in practice, and defining a human height based on footprints is relevant and important in terms of obtaining primary (up-to-date), and later evidentiary information for a successful investigation and crime detection. The approximate height of a person, as indicated in the current trace evidence literature, can be established by using a certain number of the most common methods, one of which is to establish height by the total length of the trace. However, the existing today methods for calculating human height by foot traces (footprints) have certain disadvantages, which are mentioned in this article. The article purpose is to analyze current known methods and techniques for determining human height by footwear (feet) traces, conducting practical research on a given topic, indicating objective defects and the presence of a number of errors that are not taken into account while calculations, formulation of a reasonable conclusion based on the analyzed results of an examination. In the course of the analysis of forensic practice, a number of problematic issues was identified that make it difficult to objectively determine a person’s height by footwear traces, namely: non-conformity between the real value of human height and the height value calculated according to the most common formulas given in the forensic literature; non-compliance with standards by manufacturers while the production of shoes; lack of catalogues on shoe production, information on trace formation and the environment when examining a crime scene. All the above factors have a significant impact on the establishment of real human height by foot traces (footprints), and the absence or variability of at least one of these indicators leads to significant differences in the final values. Our research has shown that each individual foot length corresponds to not one, but several height indicators at once. At the same time the limit intervals of the height range are not the same for all foot lengths (3-20 cm for men and 6-20 cm for women). The above-mentioned discrepancies in the data are unacceptable while criminal investigation for the persons involved in crimes commission. The methods of establishing a person’s height described in the forensic literature are imperfect and require modification or revision. The conducted analysis indicates the necessity for further research on correlation dependence of the foot length and a person height taking into account all variables of indicators which have been listed above, since the efficiency of the way for establishing a person height by foot and footwear traces will depend on the right adjustment of the given parameter.

Abstract:
In this paper, a series of model tests about the trapezoidal filling structures filled with tire reinforced concrete particles has been conducted to study their stability and the ultimate bearing capacity. The effects of the reinforcing tire slices on the global stability and ultimate bearing capacity of the model were investigated, the results show that the tire slices reinforcement can reduce the total settlement of the trapezoidal filling structure, and the ultimate bearing capacity of the reinforced trapezoidal filling structure with tire slices is obviously improved. Among them, the settlements of crushed concrete particles reinforced with bottom layer, top layer, and two layers (both bottom layer and top layer) waste tire slices are 11.5%, 37.7%, and 46.2% less than that of unreinforcement, respectively. Compared with unreinforcement, when the top layer of the model is reinforced with tire slices, the Earth pressure values at the top layer and the bottom layer are reduced by 21.1% and 22.7%, respectively; the Earth pressure values at the top layer and the bottom layer are reduced 6.3% and 14.3%, respectively, when the bottom layer of the model is reinforced with tire slices, and the Earth pressure values at the top layer and the bottom layer are reduced 23.4% and 32.9%, respectively, when the two layers of the model are reinforced with tire slices. The sliding surface of the pure concrete particles filled trapezoidal structure is continuous and runs through the whole trapezoidal filling structure slope; the sliding zone of reinforced trapezoidal filling structure with tire slices decreases with the laying of tire slices.

Abstract:
Most of the today’s concrete structures are older than tenyears, and the need to strengthening existing structures is growing steadily. This is due to various reasons such as degradation due to ageing, environmentally induced degradation, poor initial design or construction and lack of maintenance, to name a few. Among the benefits of strengthening existing structures are; less impacts on the environmental and financial benefits. Therefore, there is a need to find alternative ways to strengthen concrete structures more effectively. For the past decades, several different strengthening methods have been studied. Two examples are externally bonded reinforcement (EBR) and near surface mounted reinforcement (NSM). The outcome of these studies has shown a significant enhancement to the structures. Steel plates and rebar have been used to strengthen concrete structures and have shown good increases in flexural capacity. For this purpose, resins have been used to implement the steel plates and rebar, e.g. shotcrete and epoxy. Due to the weight of steel and its sensitivity to corrosion, new materials have been sought. A promising material for this use is the fiber reinforced polymers (FRP). There are several types of FRP such as, carbon fiber reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP) and aramid fiber reinforced polymer (AFRP). These new material has shown a better performance, due to their light weight, resistance to corrosion,etc. NSM and EBR perform extremely well in practice as long as sufficient anchorage is provided. However, a premature debonding has been observed by several researchers. This report will study an alternative method to reinforce existing concrete structures called “Side Near Surface Mounted Reinforcement (S-NSMR)” in association with a project run by Gabriel Sas at Luleå University of Technology. This is compared to Bottom Near Surface Mounted Reinforcement (B-NSM), which is a well-established method. It is assumed that the fiberutilisation will increase in NSM applied on the side of the beam. If this hypothesis is proven correct, the proposed method will also solve a major constrain in the utilisation of the NSM technique. In certain cases, the bottom of a beam is not fully accessible for strengthening using bottom Applied NSM techniques due to e.g. partition walls or beam-column joints. To test the effect of S-NSMR seven concrete beams, one reference beam with no fiberreinforcement and two sets of three, for S-NSMR and B-NSMR respectively with different CFRP-rebar length, were tested in the laboratory. An analytical calculation has also been carried out. In this thesis, a parametric study is performed with FEM software Atena. The thesis begins with a study of the failure phenomena occurring in the earlier mentioned strengthening method. A benchmark model is then modelled with a good comparison to the experimental results. An idealised model of the steel reinforcement in the concrete beam is used according to Eurocode 2. Material parameters in concrete are calculated according to Atena theory documents. The influence of creep and shrinkage are considered by reducing the elastic modulus of concrete by 25 %, reducing the tensile strength by 50 % and fracture energy accordingly. Thereafter, three additional parameters were chosen to continue the parametric study with Atena, 1) CFRP with E-modulus 160 GPa, 2) two different position in cross-section height of S-NSM and 3) five shorter CFRP-rebar each 100 mm smaller than the previous rebar. The behaviour of the two reinforcing types is then compared. The first parameter is, CFRP with a smaller E-modulus. It could be observed that all beams lost their stiffness, especially after yielding of the steel reinforcement. A small improvement in ductility could also be observed. The utilisation rate of CFRP increased by 13-16% in the case of S-NSM and 18-20% in the case of B-NSM. The second parameter is, different position of CFRP along the height of the beams cross-section in S-NSM beams. The positions of the CFRP was lowered in two steps. In each case an increase in stiffness and a decrease in ductility could be observed. However, the increase of the stiffness was still smaller than the stiffness in the B-NSM, in all cases. The failure mode changed from a ductile (concrete crushing) type to a more brittle kind (peeling-off concrete), due to large flexural cracks at the end of the CFRP-rebar.   The utilisation rate of CFRP-rebar, is decreased in each S-NSM beam except for S-NSM 2 with the height 25 mm. The reduction in the utilisation rate of the CFRP is 7-32 % and in S-NSM 2 with the height H25mm showing an increased in utilisation rate by 7 %. The third is parameter, different length of CFRP-rebar. In the case of S-NSM, the failure mode changed from a ductile failure mode to a brittle failure mode. The utilisation rate decreased with the decrease in CFRP length. In three of five cases, the S-NSM shows a higher ultimate load-displacement relation, and in all five cases the maximum tensile strains in the CFRP were higher in S-NSM than B-NSM. Even though the stiffness in the S-NSM is lower than the B-NSM, it would be more preferable to use the S-NSM than B-NSM, because of its higher ultimate load and lower displacements.

When reading the two words ´bottom line`, most business people think of the traditional accounting policy at the bottom of a company´s income statement, where the truth will out; profit or loss. But back in the mid-1990s, John Elkington developed a new accounting framework with these two words and called it The Triple Bottom Line (TBL). It was created for a new measurement approach that encompasses three dimensions of work ethics: the environmental, the social and the financial. The triple bottom line framework is also known as the three P’s: Planet, People, and Profit. The purpose of this study is to find out if implementing TBL approaches such as environmental and social objectives could have an influence on the ´bottom line` for companies within the athletic footwear industry from a financial perspective. The companies that serve for this study will be the top performer within the athletic footwear industry related to their market share. Older studies have shown quite impressive variances between the different companies in this specific industry. Not all companies are presenting great result or an upwards trend in their profitability while implementing TBL approaches. The company Nike is the only athletic footwear brand that shows a continuous rise in its profit dimension while focusing on the social and environmental impact on the same time. This study shows that successfully applying TBL approaches while increasing the companies’ profits at the same time is easier said than done.

Abstract:
This chapter examines codes of conduct and factory certification in the Indonesian apparel and footwear industry. With democratization, independent unions, and relatively progressive law on the books, Indonesia seemed poised for the growth of responsible factories. And yet certification to the leading standard (SA8000) proved rare. Unions and labor NGOs engaged in bottom-up monitoring of codes of conduct, using the reputations of Nike, Adidas, and other brands as leverage. But the modest improvements that followed were overshadowed by the loss of orders and the migration of the industry within and across national borders. Ironically, while factory-centered labor standards have been fairly weak, the Indonesian labor movement has proven stronger than expected in other arenas. Using qualitative and quantitative evidence, this chapter reveals the muted significance of codes of conduct, the ways in which activists sought to amplify them, and the reasons for their limited success.

Abstract:
AbstractThe evident failure of voluntary corporate codes of conduct and their monitoring has further intensified debates over the purchasing practices and legal accountability of transnational corporations. This article analyses the development of International Framework Agreements as an alternative approach advanced by trade unions and describes the characteristics of these instruments, pointing out their strengths and weaknesses concerning implementation and monitoring. It specifically focuses on the Indonesian Protocol on Freedom of Association, a special framework agreement concluded between Indonesian trade unions and international sportswear firms to protect freedom of association and trade union rights in the Indonesian textile, garment and footwear industries. After presenting the protocol’s content, the article discusses findings concerning the implementation and monitoring of the agreement, based on interviews conducted by the author in Indonesia between November 2018 and January 2019. It identifies several key factors that led to the successful promotion of strong trade union rights in the formation phase of the agreement, namely public awareness due to intensive campaigning around a mega sporting event, strong support from different civil society actors and the presence of a neutral facilitator. Overall, the Indonesian Protocol on Freedom of Association is an example of a bottom-up process that strengthens the signatory trade unions and thus serves as a potential model for actors in other countries.

Abstract:
The analysis and classification of shaping methods in the design of shoe bottom parts, and the investigation of research methods of automation of the design process of shaping shoe bottom parts to increase the efficiency of the design process and reduce the complexity of manufacturing products at the stages of technological preparation. Based on the use of means of transformation and harmonization, the structure of the stages of shaping of art objects to obtain modern shapes was developed, which made it possible to implement a new approach to the artistic design of footwear. On the basis of the developed approaches to the choice of shapes and shaping methods sketches were created and 3D models of shoe bottom parts with the subsequent program analysis of loading on a sole were developed. New shapes shoe bottom parts have been developed with the help of transformation principles and a model has been made by automated design methods, which can be used in technological preparation for the manufacture of light industry products. Regularities of transformation processes for improvement of artistic design of footwear on the principles of bionics and stylization are established. Given that the complexity of structures and the emergence of new spatial solutions pose designers more complex technical tasks for the implementation of design projects, a method was proposed of calculating the strength and stability of products of complex geometric shapes, taking into account the materials from which they are made. As a result of the performed work, women's shoes of the “shuttle” design with an over seam back allowance were developed. Given the fact that the shoes should be comfortable and meet ergonomic indicators, the materials, the shape of the pad, and the design of the model were selected. The purpose of this shoe is everyday wearing, focused on the youth category of consumers. The used technique allows shaping a wide range of various prototypes of footwear, using a small number of transformed products. Determining the most loaded areas made it possible to propose measures to improve the design of shoes of non-standard models. And the combination of the given techniques with modern high-tech production helps to save means of the manufacturer and to increase the service life of footwear.

Abstract:
Abstract Men and women with lower limb amputations struggle with managing the balance between prosthesis alignment and shoe heel rise. A novel prosthetic ankle-feet system is being developed to support a wider range of footwear options for men and women with lower limb amputations. Each rigid foot is customized to fit the footwear of choice and can be rapidly attached to (or released from) an ankle unit which remains attached to the prosthesis. The ankle unit has a mass of 318g and is small enough to fit in the design volume of a 22cm foot across a range of heel rises. The ankle uses elastomeric bumpers arranged in a wiper design to maximize space efficiency. Structural testing has shown that the 3D printed custom Nylon 12 feet withstood 4584N of forefoot loading without failure based on the ISO 10328 loading parameters, indicating suitable strength to support safe human use in the laboratory. The feet have a mass of 446g. Feedback from two women Veterans with lower limb amputations reinforced the importance of improving access to shoes with different heel rises. Future activities will include cyclic fatigue testing, additional weight reduction, and incorporating suggested design refinements.

Abstract:
Abstract In order to effectively use the recycled aluminum cans, many applications of aluminum are being explored. One of the most obvious applications is to reinforce with wood or others, to form sandwich composites. The goal of the proposed work is to conduct the research to develop constructional products, which would permit reuse of aluminum cans instead of destroying the structure by melting or trashing. With that goal in mind, our specific objective of this study is to evaluate the stiffness and failure behavior of recycled aluminum reinforced composites under three-point bending for use in composite industries. Composite specimens containing the end sections of the can sandwiched between top and bottom layers of wood are investigated. The results of bending stiffness and failure behavior of sandwich composite panels obtained from the three-point bending tests are presented and discussed.

Abstract:
Abstract Structural health monitoring (SHM) has become an integral part of essential and costly to replace infrastructures such as bridges and buildings which degrade during their lifetime. Understanding the structural behaviour of these infrastructures is critical for assuring their structural integrity and safe operating conditions. In this study, the structural performance of a reinforced concrete beam was examined under flexural loading. Distributed optical fibre sensor (DOFS) was attached to the beam’s bottom surface, and Optical Backscattered Reflectometry (OBR) technology was used to measure the surface strain. A three-point bending test was performed, and the sensor responses were acquired. Unusual high strain peaks were observed at the bottom surface of the beam due to the formation of hairline cracks. Subsequently, the Concrete Damaged Plasticity (CDP) based Finite Element Analysis (FEA) was performed to simulate the plastic behaviour of concrete beam using ABAQUS 2019 commercial software. The FEA results have strong agreement with the strain pattern observed from the DOFS. Therefore, DOFS and CDP technique based FEA can be successfully used to investigate the plastic damage pattern inside the concrete beam and distributed sensing demonstrates a greater capacity for long-term monitoring of the structural health of concrete structures.

Abstract:
The printed wiring board (PWB) has becomes relatively smaller due to the downsizing of electric devices. Higher densification has been advanced by the circuit formation of multi-layer PWBs in the current manufacturing of these boards. In current manufacturing of multi-layer printed wiring boards, a method frequently used is to laminate the core with insulating resin as build-up layers. Microvia drilling using laser technology has become the prevailing method of machining smaller blind via holes. Aramid fiber reinforced plastic (AFRP) is considered suitable material for the build-up layers, because it is efficient in laser drilling. However, heat damage in the hole has been a problem because the laser drilling cause a heat damage to the PWB materials. The poor hole quality, such as the carbonization of the resin and the peel around circuit copper foil/core material, causes decrease in the reliability of circuit connections. In the present report, first, we took multi layer PWB-reinforced by aramid unwoven cloth, and measured the temperature distribution of the circuit copper foil during laser drilling using a thermocouple. Second, we proposed a heat input prediction model using a finite element method (FEM), considering the change of laser absorption of the circuit copper foil surface. Finally, we carried out a thermal stress analysis based on the temperature distribution, and confirmed the efficiency of this analysis. As a result, the calculated temperatures by this model, considering the variation of the absorption of foil surface during laser drilling, are in good agreement with the experimental temperatures. It is confirmed that this model is effective in estimating the temperatures and thermal stresses in the bottom copper foil during laser drilling of the build-up layers.

Abstract:
<p>To design flat slabs directly supported on columns, the punching shear resistance of the slab is a main factor. It can be increased in the vicinity of the slab-column connection with punching shear reinforcement, like bent up bars or shear studs, to bear the high reaction forces. However, the usage of punching shear reinforcement requires the knowledge of special design rules and often leads to problems and deficiencies in construction.</p><p>Fiber reinforced concrete seems to be a promising alternative to conventional punching shear reinforcement. To investigate the load bearing behavior of the slab-column connection using fiber reinforced concrete, a total of eight punching shear tests were performed. The specimens were realized with a typical top and bottom flexural reinforcement, but without punching shear reinforcement. Varied parameters were the slab thickness with 250 mm and 300 mm and the fiber content V<sub>f</sub> with 0.5 Vol.-% and 1.0 Vol.-%. To investigate the influence of modern fiber types, normal- and high-strength steel fibers with normal- and double-hooked-ends were used.</p><p>In all eight experimental tests, the intended punching shear failure was achieved. The capable load using fiber reinforced concrete increased by 20 % to 50 % compared to the reference tests without steel fibers, depending on the fiber type and the fiber content V<sub>f</sub>. Additionally, this load increase was accompanied by a significant improvement in ductility. The post-cracking behavior was noticeably influenced by the used steel fiber type. An influence of the slab thickness or steel fiber type on the shear strength contributed by the fiber reinforced concrete could not be determined.</p>
