Industrial innovation in Britain, during the eighteenth and nineteenth centuries, stimulated the introduction of the factory system and the migration of people from rural agricultural communities to urban industrial societies. The factory system brought elevated levels of economic growth to the purveyors of capitalism, but forced people to migrate into cities where working conditions in factories were, in general, harsh and brutal, and living conditions were cramped, overcrowded and unsanitary. Industrial developments, known collectively as the 'Industrial Revolution', were driven initially by the harnessing of water and steam power, and the widespread construction of rail, shipping and road networks. Parallel with these changes, came the development of purchasing 'middle class', consumers. Various technological ripples (or waves of innovative activity) continued (worldwide) up to the early-twenty-first century. Of recent note are innovations in digital technology, with associated developments, for example, in artificial intelligence, robotics, 3-D printing, materials technology, computing, energy storage, nano-technology, data storage, biotechnology, 'smart textiles' and the introduction of what has become known as 'e-commerce'. This paper identifies the more important early technological innovations, their influence on textile manufacture, distribution and consumption, and the changed role of the designer and craftsperson over the course of these technological ripples. The implications of non-ethical production, globalisation and so-called 'fast fashion' and non-sustainability of manufacture are examined, and the potential benefits and opportunities offered by new and developing forms of social media are considered. The message is that hand-crafted products are ethical, sustainable and durable.

Web documents specified with HTML and CSS is displayed with high quality on the web browser. However, basically, any printed pages don't have the same quality of softcopy. The reason is HTML and CSS is not suit for printing. The XSL-FO(XSL-Formatting Object) is Formatting Language for imaging of web document and The PostScript is one of the most famous PDL(Page Description Language). To get high-quality pages, we propose the design of converter which translate XML-FO into PostScript format. Using the designed converter, we can get hardcopies with high quality.

Since the introduction of Nanoimprint in the mid-1990s, Nanoimprint lithography, a low-cost, non-convential method, has been the dominant lithography technology that guarantees high-throughput patterning of nanostructures. Based on the mechanical embossing mechanism, Nanoimprint lithography creates the nanopatterns on the polymer material cast on the substrate. In essence, the process needs nanofabrication equipment for printing with the adequate control of temperature, pressure and control of parallels of the stamp and substrate. This article introduce the possibility and reality of the thermal control on the hot plate using a CFD code. Numerical computation has been conducted for assessing the feasibility of a hot plate($120{\times}120\;mm2$). PID control is adopted to ensure high temperature uniformity in several zones. Parallel experiments have also been performed for verifying thermal performance. Not only show the results the optimum number of thermocouples related to controllers but also suggest that the thermal simulation using a CFD code would be an alternative method to design and develop the thermal control equipment in the financial aspect.

In this study, three kinds of wearable fashion prototypes were developed using 3D printers with the goal of developing a practical production method for daily clothes. Prototypes were modeled using Rhinoceros software and developed using FDM 3D printers and TPU filaments. The results of this study are as follows. First, it confirmed the possibility of FDM-type entry-level 3D printers as a tool to develop wearable fashion products. Second, TPU filaments that are soft and ductile are highly likely to be used as a clothing material. Third, patterns designed through the 3D modeling process can be sampled directly to a 3D printer and easily corrected and supplemented. Fourth, it was confirmed that TPU prints of about 1.00mm thickness can be sewn with fabric using sewing machines through the development of 'Prototype 1' and 'Prototype 2'; in addition, hand stitching is also possible. Fifth, as in the case of 'Prototype 3', it is possible to fabricate a garment fit enough to the body if the clothing configuration is designed to connect the basic module using TPU filaments. In the future, the development of wearable fashion prototypes using various materials and 3D printing technology will help diversify everyday clothes.

This research is aimed to examine the differences through comparative analysis of the Earth Science contents in the science textbooks between Korea and DPRK. The contents of level and scope in science textbooks between Korea and DPRK are analysed by TIMSS frameworks. The results of this research are as follows : 1. The science textbooks of DPRK is lower in quality of paper, printing to that of Korea, and the illustrations, editing design in the textbooks of DPRK are fewer, monochromic and monotonous while those in Korea. 2. The contents of Earth Science in DPRK's science textbooks rank 37.0%, but those of Korea's science textbooks rank 25.5% of the whole textbooks. The learning units related to Earth Science are generally similar to the level and scope in science textbooks between Korea and DPRK. The type of inquire activities in the textbooks of DPRK largely takes on the model experiment, and it was shown that the number of experiments directly made by children is very small compared to Korea' textbooks. 3. There are lots of differences in Earth Science learning terms and predicates used in the textbooks between Korea and DPRK.

Several costs including printing and management are added in commerce by vouchers. In this case that a voucher is digitalized and flown through mobile phones, these costs are diminished considerably. Also, as mobile commerce is on the increase according to the activation of smart phones, NFC technology with near distance communication is gave attention to. Therefore, researches for using NFC-based electronic vouchers to pay electronically on mobile are made. To analyze the flow path of electronic vouchers, which helps marketing strategy, this paper proposes the method to put useful data into them. The proposed method utilizes object memory model. The proposed electronic voucher includes the block for flow history data in addition to its information. In the future, we will implement and test this electronic voucher.

This study looked into the trend of expression of animal motifs that appears in modern fashion, and the values embedded in them. As to the research method, empirical analysis was performed on the works presented at the four global collections of Paris, Milan, New York and London from 2001S/S to 2010F/W, as well as a literature review. As a result, animal motifs applied in modern fashion appeared in material groups, such as leather or feather. The first group shows a realistic material feel, with artificial leather or fur, expressed in a transformed complex animal motif, with process skill or various methods of expression. The second group is the case of a single motif or reality, mode, and ion pattern. Printing is a generic expression, but patchwork, collage or bead ornament are also used, and expressed in the various forms of pattern: pattern in a single animal, pattern in different animals, and pattern combining both animal and other shape. The third group is a small decorative ornament, including headset or accessory and makeup, which is transformed in an animal-characterized motif into part of clothing components for expression, or to set the real animal to the stage for a performance. The embedded values were also categorized as natural beauty, sensual female beauty, pleasure, and ornamentation, which could be an endless spiritual source, and a breakthrough that enables us to show a creative and new aesthetic for the modern fashion field.

Background: Protection from yellow dust and particulate matter is ensured by the use of respirators among the Korean citizens and workers. However, the manikins used to test the performance of the same were manufactured considering western facial specifications owing to which they do not represent Korean facial characteristics. Methods: Analysis of the data from the 6th 3D anthropometric survey of Koreans (Size Korea; 2010-2013) of 4,583 people aged 7 to 69 years was performed to obtain their facial dimensions. We subsequently clustered 44 facial measurements using Design X software, followed by the creation of the cluster centroid. Results: Three 3D head forms were developed-small, medium, and large, and their images were stored in ".stl" format for 3D printing. The facial widths and lengths of the three head forms were 127.1 mm × 90.6 mm, 143.2 mm × 104.0 mm, and 149.1 mm × 120.2 mm, respectively. Conclusion: We developed manikin head forms according to the facial dimensions of the Korean population, which was essential in evaluating respiratory protective equipment. These head forms can be used to test the performance of respirators considering the facial dimensions of the Korean population.

The dissolved oxygen (DO) sensors were fabricated by screen printing method, and potable dissolved oxygen measurement system was fabricated for low cost products. The fabricated sensors had high current change and fast response according to dissolved oxygen concentrations in the applied voltage of 0.7 V. The DO measurement system was consisted of MCV, amplifier, filter, power supply and display. DO concentrations were programed to display as digital percentages by converting the analog value. It is expected that the fabricated DO measurement system can replace the expensive commercial DO meter, because it reveals the high accuracy of ${\pm}0.5%$ to the standard solution and the response time of about 100 sec like the commercial DO meter.
