Footwear Comfort

Advanced technologies for modelling and production are an important part in the whole process of product manufacturing. These advancements have changed the way of product development and play an important role in customization. In the footwear industry, as in any other industry, the use of these technologies is widely spread. Footwear comfort is one of the main selection criteria for purchase. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized. As a part of personalization, feet’s plantar pressure maps taken from 1 participant gave a better explanation of weight distribution of each foot. Following, sole personalization according the plantar pressure maps for each foot gives the possibility to obtain the best least material design according to the feet’s pressure while maintaining biomechanical performance.

Footwear sector is a very significant segment of Leather and NonLeather products in India. The size of Indian Domestic Footwear Industry is estimated to be worth 1919 million pairs where leather and non-leather Footwear per capita consumption is estimated to be approx. 1.61 pairs. The major component of footwear sector is a design, product development, clicking, closing, component, lasting & finishing. Advanced technologies in the area of shoe design systems, automation, cost savings and productivity improvements as well as enabling new developments in footwear sector in India. Although today footwear is produced using many similar methods to those employed all those years ago, obvious technological innovations in machinery, raw materials, production and testing techniques have changed what was to all intents and purposes a cottage industry into a multi-billion dollar sector. At the same time, recent years have seen a distinct shift in factory location away from the traditional industrial heartlands of Europe and North America to the new lands of opportunity, primarily in Asia. The purpose of this paper is to review the areas where advanced technologies can significantly affect the way of footwear sector is practiced. Strategies for implementation of the necessary changes in practice are also discussed.

Intensive manual labor enterprises in the developed world face challenges competing with products imported from countries where manufacturing costs are low. This reduces the volume of domestic production and leads to rapid loss of knowledge and experience in production processes. This study focuses on the Israeli footwear industry as a case study. Qualitative methodologies were applied, including in-depth interviews and field observations. A literature review on previous research, and contemporary trends was conducted. The field research examines challenges along the value chain in small factories. It finds that mass production paradigms impose a decentralized process between designers and manufacturers and therefore do not leverage local potential into a sustainable competitive advantage for small factories. The proposed solution is a digital and technological platform for small manufacturing plants. The platform mediates and designs the connections between production, technology, and design and enables the creation of a joint R&D system.

In this research, a hybrid approach for path planning of autonomous ships that generates both global and local paths, respectively, is proposed. The global path is obtained via an improved artificial potential field (APF) method, which makes up for the shortcoming that the typical APF method easily falls into a local minimum. A modified velocity obstacle (VO) method that incorporates the closest point of approach (CPA) model and the International Regulations for Preventing Collisions at Sea (COLREGS), based on the typical VO method, can be used to get the local path. The contribution of this research is two-fold: (1) improvement of the typical APF and VO methods, making up for previous shortcomings, and integrated COLREGS rules and good seamanship, making the paths obtained more in line with navigation practice; (2) the research included global and local path planning, considering both the safety and maneuverability of the ship in the process of avoiding collision, and studied the whole process of avoiding collision in a relatively entirely way. A case study was then conducted to test the proposed approach in different situations. The results indicate that the proposed approach can find both global and local paths to avoid the target ship.

Purpose The research paper aims to unveil the practical use of Lean Six Sigma and its effectiveness as a business survival strategic tool by a chemical product realization concern, as well as to establish the market and business performance impacts on the manufacturing entity. Design/methodology/approach A case study approach was pursued with a multi-national chemical manufacturing entity in South Africa. A comprehensive literature research was undertaken to establish the contemporary tools used for implementing Lean Six Sigma, and the classification and flow of tools and steps undertaken to ensure the successful and effective application of Lean Six Sigma in a manufacturing organization and the benefits derived. The critical success factors and reasons of ineffective use of tools are reviewed. To ensure that a comprehensive research was conducted which is relevant to the body of knowledge in engineering, recent articles on the application of Lean Six Sigma were selected and reviewed during the progress of the study to add impetus to the relevance of the findings. Findings The research findings were mainly based on the inferences obtained from a chemical product manufacturing concern in South Africa, to distinguish the efficacy and relevance of Lean Six Sigma as strategic business survival tool and imputing strategic resonance to corporate strategy. Research limitations/implications This research was limited to distinguishing Lean Six Sigma as a business survival strategic tool and an ultimate enhancer of market performance for a chemical product manufacturing entity. The implementation and evaluation of the Lean Six Sigma methodology as a business survival strategic and market performance enhancement option for the case study organization was entailed as the corollary of deductive resemblance to similar entities. Practical implications This study enables continuous improvement practitioners to evaluate the Lean and Six Sigma practices. The advantages posed by the simultaneous and optimized application of the two approaches versus individual application were assessed and verified to produce enhanced continuous improvement. This poses further challenges to scholars and academics to pursue further researches on the practicality of applying Lean Six Sigma as a strategic option. Originality/value The paper prompts the efficacy of well publicized methodologies and evaluates their implementation for strategic performance for manufacturing organizations. The practical application, constraints and resultant effects of deploying Lean Six Sigma were reviewed to give impetus to the methodology.

The author presents a methodology which is used first to model a product-manufacturing-and-distribution system, and then to predict the resulting changes in environmental impact from changes either in taxation or in costs of inputs. A case study of the paper sector in the eastern and central United States is developed, derived from the 1993 US Commodity Flow Survey. From an analysis of five scenarios, two central findings arise: (1) the model is found to be unresponsive to even large changes in transport taxation, so an environmental policy which considers both transportation and production aspects at the same time is favored, and (2) fluctuations in raw-material costs can have an influence on environmental impact as great as or greater than that of changes in taxation levels.

Structured Approach

The research presented in this paper proposes a novel quantitative model for decomposing and assessing the Value for the Customer. The proposed approach builds on the different dimensions of the Value Network analysis proposed by Verna Allee having as background the concept of Value for the Customer proposed by Woodall. In this context, the Value for the Customer is modelled as a relationship established between the exchanged deliverables and a combination of tangible and intangible assets projected into their endogenous or exogenous dimensions. The Value Network Analysis of the deliverables exchange enables an in-depth understanding of this frontier and the implicit modelling of co-creation scenarios. The proposed Conceptual Model for Decomposing Value for the Customer combines several concepts: from the marketing area we have the concept of Value for the Customer; from the area of intellectual capital the concept of Value Network Analysis; from the collaborative networks area we have the perspective of the enterprise life cycle and the endogenous and exogenous perspectives; at last, the proposed model is supported by a mathematical formal description that stems from the area of Multi-Criteria Decision Making. The whole concept is illustrated in the context of a case study of an enterprise in the footwear industry (Pontechem). The merits of this approach seem evident from the contact with Pontechem as it provides a structured approach for the enterprises to assess the adequacy of their value proposition to the client/customer needs and how these relate to their endogenous and/or exogenous tangible or intangible assets. The proposed model, as a tool, may therefore be a useful instrument in supporting the commercialisation of new products and/or services.

There are many studies conducted about Barbie dolls. However, it has not been investigated how these toys reflected on gender perceptions of children. That is this topic is still an issue of concern. On the other hand, games give crucial clues regarding making sense of children’s worlds. Through this study, it was aimed to analyze the reflections of Barbie culture on children’s dramatic game processes. The design of the study was case study one of qualitative research designs aiming to obtain information in depth. The participants consisted of seven children in 5-year class of a nursery school and prefer to play in dramatic game center during game time. The data of the study was collected by observations. Within data collection, the whole process was recorded as videos in order to minimize data loss. In total, video record of 280 minutes was obtained. The data was analyzed by content analysis method. It was found out that children frequently emphasized physical features playing with Barbies, besides they involved in gendered conversations. Moreover, it was revealed that Barbie culture increased the gendered utterances of children when handled in terms of gender. Our study is parallel to the results of limited number of studies regarding this matter.Extended English abstract is in the end of PDF (TURKISH) file.ÖzetBarbie bebeklere ilişkin olarak yapılmış bir çok araştırma bulunmaktadır. Ancak bu oyuncakların çocukların toplumsal cinsiyet algılarına nasıl yansıdıkları yeterince araştırılmamıştır. Yani bu konu halen merak konusudur. Oyunlar ise çocukların dünyalarının anlaşılmasında önemli ipuçları sunarlar. Bu çalışmada Barbie kültürünün çocukların dramatik oyun süreçlerine yansımalarının incelenmesi amaçlanmıştır. Araştırmanın yöntemini derinlemesine bilgi edinilmesini amaçlayan nitel araştırma yöntemlerinden durum çalışması oluşturmaktadır.  Araştırmanın çalışma grubunu bir anaokulundaki 5 yaş sınıfına devam eden ve oyun zamanında dramatik oyun merkezinde oynamayı tercih eden yedi çocuk oluşturmuştur. Çalışmada veriler gözlemler yoluyla elde edilmiştir. Veri toplama sürecinde, veri kaybını en aza indirmek için sürecin tamamı kamera kaydına alınmıştır. Toplamda yaklaşık 280 dakikalık kamera kaydı elde edilmiştir. Veriler içerik analizi yöntemiyle analiz edilmiştir. Araştırmada çocukların Barbie’lerle oynadıkları sırada sıkça fiziksel özelliklere vurgu yaptıkları, ayrıca cinsiyetçi söylemlerde bulundukları belirlenmiştir. Ayrıca «toplumsal cinsiyet» bakımından ele alındığında Barbie kültürünün çocukların cinsiyetçi söylemlerini beslediği sonucuna ulaşılmıştır. Araştırmamız konuya ilişkin olarak yapılmış sınırlı sayıdaki çalışmanın sonuçlarıyla örtüşmektedir.

This article is entitled Becoming Lesbians: A Symbolic Interactionism Study of Lesbian Identity (Case Study in the City of Surabaya). Researchers focus on lesbian individuals not on the lesbian community. The problem raised by the researcher is how the whole process of choosing someone to be a lesbian and the symbols used for interaction with other lesbians. The purpose of this study is to know how a person chooses his life as a lesbian and to find out the symbols used to interact with lesbians. The method used is a qualitative method with a phenomenological approach. In this study informants numbered four people and all four occupy their respective roles in lesbians. From the results of this study there are several reasons why someone chooses to become a lesbian: social profiles, her-story, lesbian firts time, what changes, reactions and what next. From these concepts, the conclusion is that family background does not influence a person to become a lesbian, but rather from personal experiences in the past or experiences with social relations.
