The purpose of this study is to illustrate the design of safety suits based on energy-harvesting technology, particularly targeting street cleaners who must work at night with high mobility. The design focuses on applying lightweight energyharvesting tools and illuminant into the wear. The design development reflects feedback from testers collected via survey constituting a key methodology. The development process has two main stages. Each stage uses a process of design prototyping, internal examination, test sampling, test wearing, and wearers’ feedback via survey that consists of questions on visibility, wearing convenience, and washability. The first stage results show the design of safety suits with energy-harvested LED illuminant inserted and the survey results collected from street cleaners dressed in 4 sample and 80 actual suits in total. Improved based on the first-stage survey results, the second stage designs the suits with detachable energy-harvested EL tape. From these 5 sample and 30 actual second-stage suits, the additional survey indicates that this second-stage design facilitates more visibility and convenience in washing and wearing than the first-stage design. Accordingly, one can expect that this new design can apply not only to safety suits for night workers but also to handicapped or outdoor sportswear applications in the future.

This study analyzes characteristics related to Kineticism found in different kinds of displays and arts in order to contemplate modern window displays. The standard of analysis is based on kinetic arts pioneer George Rickey’s six display factors. Projection features and movements were categorized into “Direct movements,” “Indirect movements,” and “Relative movements.” Results were obtained through analysis of different examples of each category. First, the most observed form of Kineticism was direct movements on the window display. Along with the development of science and techniques, a variety of divergent motional methods has arisen. After that followed indirect movement, which uses visual media and lights for presentation. The third was relative movements, which provides communication in practical experience; users’ motion is used to provide modification in vision. Fourth, we observed that direct movements and indirect movements can express fluidity depending on materials, inducing a sense of tension within the window display through visual stimuli together with dynamism from mechanical exposure. Fifth, when direct movements pair with relative movements, it triggers customer participation; though it does not deliberately induce participation, the effects are beyond expectation. Sixth, if indirect movements meet relative movements, the motion of lights offers a major stimulation to the customers along with various expressions, thus achieving an interactive domain.

The purpose of this study was to propose various directions for effectively proposing window displays that satisfy changing consumer needs by investigating and analyzing the characteristics of unexpected expressions used in recent Christmas windows. Research was conducted by investigating unexpectedness in window displays through literature reviews and previous studies. To observe unexpectedness in Christmas windows, website-based case images of window displays from the six years between 2010 and 2015 were collected from the department stores of Bergdorf Goodman, Printemps, Selfridges, and Isetan. Unexpected expressions in department-store Christmas window displays could be categorized into four expressive methods of hybrid expressions, figurative expressions, amusing expressions, and exaggerative expressions. The results were as follows: First, hybrid expressions are interpreted by consumers as having new or diverse meanings that change the original external forms of subjects or objects. Second, Christmas colors are used in the window backgrounds’ figurative expressions, but these windows do not use excessive expressions; furthermore, these windows personify people as animals and anthropomorphize animals as people, using subjects to depict other subjects to show unfamiliar images. Third, amusing expressions are used to decorate windows with unique and novel ideas that provide stimulation and amusement for customers and capture their attention through the composition of windows that entail childish props and elements that create funny. Fourth, exaggerative expressions deliberately stretch and expand subjects or objects in windows to elicit customers’ curiosity and interest through emphasis.

Born in the 19th century as an intermediate between the past and the future, steampunk provides a strong feeling of fantasy. The objective of this research is to understand the utilization of steampunk in all realms through an in-depth literature review and empirical study. Taking the findings as a foundation, we will analyze examples shown in fashion designs that are put into real production, and those designs that can provide inspiration for further design development. The research methodology will constitute a major analysis of advanced research, internet materials, and literature. Photo materials will be collected from professional websites for steampunk. The product method such as follows. Firstly, we will classify the internal meaning of characteristics in steampunk that are similar to the characteristics that are being researched, then take it as the standard and arrange to integrate all five features: restoration, pluralism, duplicity, resistibility and abnormality. We will spread out the design based on images from advanced research. Secondly, in order for to design a steampunk product, I decided on four themes: devastated environment, brutal wars, cool-headed machinery, and the overlap of the future and the past. Inspiration was acquired from representative movies and animations featuring steampunk. Thus, new directions for fashion design with steampunk features can be discovered. It raises the feasibility of this combination in modern society. In the future with the development of technology, it functions as a design that is easy for users to approach.

This study examines the formative characteristics of Fold architecture and how its properties are shown in the fashion of the modern work of Issey Miyake through analysis. In this research, the Fold classification criteria for analysis features that appeared in Issey Miyake fashion features were established through research literature on Fold architecture and leading research. Empirical data collection was conducted for Issey Miyake's work and collection by collecting photo materials, and design concepts and the results are analyzed in terms of features. Study ranges of Issey Miyake’s creative design development are Pleats Please, A-POC, 132.5 project, and collections from 2000 to 2014. The conclusion is as follows. First, design concepts presented in the Issey Miyake fashion features of Fold are Hybrid, topology, and uncertainty. Hybrid look for the meaning of fashion, which is the interaction between the wearer and garments. The concept of topology designs clothing, focusing on interrelationship of the body and clothing, and pays no attention to absolute size or the form of the clothing. The concept of uncertainty is an uncertain form that is infinitely expandable because all the elements have openness and uncertainty due to the determined incomplete state by the creator. Second, in the results presented in the Issey Miyake fashion features is the destruction of the boundary and diagram form. The destruction of the boundary is free from traditional clothing. The diagram form is a geometric form which does not create a Dart or Princess line.

This study attempted to figure out the usage of the modular system in other fields through literature review and empirical study, analyze its structural method in fashion. After analyzing architecture & product-related books, the Internet data and previous studies, the modular system's five structural methods were obtained. Then, 991 photos of women's clothes from 2003 to 2014 were collected through the fashion websites in Korea and abroad. The results can be summarized as follows: First, the following five structures were derived: assembling structure, overlapping structure, arrangement structure, inserting structure and folding structure. Second, according to analysis on the structural method of the modular system in modern fashion, overlapping structure (34%) was the most common. Third, in fashion, the use of fastener for installation and removal is important for assembling structure. In terms of overlapping structure, 3D volume by vertical accumulation was commonly observed. Arrangement structure revealed a horizontal and flat shape through simple arrangement. In inserting structure, on the contrary, non-standardized modules were used as a part of clothes or decorative elements. In folding structure, origami technique for reduction and expansion was used.

The most effective chemical pretreatment method for Scenedesmus dimorphus was evaluated based on solubilization rate and saccharification yield. When 1% of S. dimorphus with 0.5 N of chemicals such as HCl, H2SO4, HNO3, NaOH and KOH was autoclaved at 120oC and 1.1 atm for 60 min, the solubilization rate was high with alkali chemicals while the saccharification yield was low compared to that with acid chemicals. The pretreatment efficiency was significant in order in HNO3, HCl and H2SO4, however, HCl would be effective for field application considering the cost. The proper concentration and time to treat with HCl were concluded in 1 N and 10 min. In the conditions with 1 : 1 mixed acid chemicals such as H2SO4+ HNO3, HCl + HNO3 and HCl + H2SO4, the solubilization rate was similar to that with single acid treatment, while the saccharification yield was enhanced about 34% in the mixed condition with H2SO4 and HNO3 compared to that treated with H2SO4.
