(a) State the chemical structure of Protein explaining the difference between animal and vegetable sources. [5] (b) (a) Outline three ways of improving the protein content in the diet of people living in developing countries. [3] Award marks for sound knowledge and clear definitions based on: Proteins are complex molecules made up of the elements: carbon, hydrogen, oxygen and nitrogen; sometimes proteins also contain sulphur and phosphorous depending on the specific protein. (2) The molecules are made of small units called amino acids joined together by peptide linkages or like links in a chain (1) where different combinations of amino acids create different protein chains. On hydrolysis or digestion in the body, proteins break down to polypeptides and eventually to amino acids which can then be used to recreate the specific proteins needed for body growth. These units are joined together by peptide linkages. (1) Animal proteins can be classified according to their molecular shape either fibrous or globular whilst plant proteins are more difficult to classify, but can be divided into glutenins or prolamines. (1) or Animal proteins are complete proteins because they tend to contain all the essential amino acids(high Biological Value). Plant proteins are incomplete (Low biological Value) because they lack one or two of the essential amino acids. (2)

55 GCE DESIGN & TECHNOLOGY Specimen Assessment Materials Account for the impact of 'fad' products in the market place on: (a) the manufacturer. [4] (b) the environment. [4] Product launch is characterised by slow growth of sales as the product is launched on the market. The company incurs large costs with advertising and promotion considerations. Rapid growth of the product then follows depending on impact on target audience, and the 4 P's, and there is a steady rapid rise in growth. Maturity where sales are at their maximum level and profits remain stable this is presumed for only a short period. Decline is dramatic where sales and profit begin to drop off. Products with short life cycle having adverse impact on the environment, re-use, recycling issues, energy consumption for short term profit, etc. At this point the company has t decide whether to inject incremental improvements to boost sales or to allow the decline to continue with the implications of ending production. Some products called 'fads' move very quickly through the system and have a fast turnover - quick profit; manufacturers need to be able to respond to demand to satisfy consumer trends at the time to maximise profit but this needs to be balanced against costs of design and development. [4] Credit discussions based on Products with a short life cycle having adverse impact on the environment, re-use, recycling issues, energy consumption for short term profit, etc. [4] Notes: Give credit of 1 mark for a response that merely describes the main stages of the product life cycle.

[4] (b) Describe the impact a design specification has on this process. [4] (a) (b) On-going evaluation is used to check feasibility of the food product; to select and refine the most successful features; to allow comparisons to be made to draw out the best solution to a design problem; to provide a vehicle for testing a product or feature with the target audience. On-going evaluation is important in terms of a product meeting the requirements of the design brief. Also, that the design ideas and decisions are justified by evaluative annotation. [4] The design specification should be referred to at strategic points in development to confirm decisions based on the factors outlined above. It controls realistic development of ideas and is a guide which aims to ensure success and provides success when satisfying design requirements and also allows focussed development of ideas. A main feature of on going evaluation is the use of the specification as a design tool to judge the quality and performance of design ideas against the initial specification. It helps the designer to keep focussed on the prime requirements of the design. [4] 7. Using examples of named food products, explain how packaging design targets particular market sectors. [8] Candidates should consider appropriate strategies for specific target groups.

Analogies / Information Transfer: thinking of a different product/object but has certain properties in common. Morphological analysis: Identifying the key features of a product and then considering different ways of achieving the features. Modelling and prototyping. Lateral thinking In addition to these, systems designers may use a new method called Concept Transfer. In this method, the concept is extracted from one typical system or product and then, the concept is applied to the other system. Compared to the technology transfer, the concept can be transferred easily to other systems 12. Quality control and Quality Assurance are important features that are considered when manufacturing products. Fully describe these terms with references to named products whenever possible. [26] Description of Quality control Total Quality Control is the most necessary inspection control of all in cases where, despite statistical quality control techniques or quality improvements implemented, sales decrease.

82 GCE DESIGN & TECHNOLOGY Specimen Assessment Materials 82 Description of Quality assurance Quality Assurance covers all activities from design, development, production, installation, servicing and documentation. This introduced the rules: "fit for purpose" and "do it right the first time". It includes the regulation of the quality of raw materials, assemblies, products and components; services related to production; and management, production, and inspection processes. One of the most widely used paradigms for QA management is the PDCA (Plan-Do-Check- Act) approach, also known as the Shewhart cycle. Using quality control systems and processes rigorously and consistently demonstrates quality assurance. The outcomes of quality control systems and processes trigger quality improvement. Electronic, mechanical or computer control systems can ensure that a process or procedure is consistently applied allowing standards to be of a certain level throughout. Systems may be adapted or de-bugged for further improvements in standards. 13. The Four Ps are significant features of selling products in the market.

Rather than using batteries or external electrical source, the radio is powered by the user winding a crank for several seconds. This stores energy in a spring which then drives an electrical generator to operate the radio receiver. He invented it in response to the need to communicate information about AIDS to the people of Africa. This has infuenced a range of wind up products including torches and Mobile phone chargers. Links can be made to products with convert alternative energy for power supplies. He now runs Trevor Baylis Brands plc, a company dedicated to helping inventors to develop and protect their ideas and to find a route to market. TOTAL FOR PAPER 100 marks
