As Taiwan has long been influenced by foreign cultures, it has diverse rich and delicate cultures, and has accumulated strong cultural energy. Meanwhile, Taiwan’s government also actively promotes policies related to the cultural and creative industry and further pushes forward the developmental trend of the creative industry. New opportunities for numerous cultural and creative products (hereinafter referred to as cultural products) are thus expanded, and they have been highly concerned by the academic circle and industry as well as have obtained great acceptance from the consumer market in recent years. After analyzing related documents, the study found that there was a considerably large difference between consumers’ cognition of cultural products and meanings that designers intended to convey. Therefore, the study aims to probe into how cultural products transmitted their cultural information to consumers after cultural elements were reinterpreted through different design skills. By adopting case studies and field research, the study analyzed and evaluated the cases of the cultural and creative industry in Taiwan, and established reference models and indicators to provide references for the companies of the industry when they design products of this kind in the future. The results of the study are: (1) The value of Taiwan’s cultural products could be effectively elevated through the introduction of craftsmanship. (2) The memory links of consumers could be effectively achieved when products were designed through consumers’ experience. (3) Cultural information could be effectively transmitted to consumers, and new cultural styles could be created when cultural products were designed with a three-layer model including strategy layer, meaning layer and technique layer. © 2016 Taylor & Francis Group, London.

Carbon nanotube field emission display (CNT-FED) represents both emerging application of nanotechnology and revolutionary invention of display. Therefore, it is an important subject to monitor the states and trends of CNT-FED technology before the next stage of development. The present paper uses patent bibliometric analysis and patent network analysis to monitor the technological trends in the field of CNT-FED. These results firstly reveal the different aspects of patenting activities in the field of CNT-FED. Then, patent network analysis indicates the developing tendency of worldwide FED production based on the synthesis of CNT materials. Furthermore, key technologies of three clusters can be identified as the depositing CNT on substrate, coating phosphor on screen and assembling process for whole device. Finally, emitter material is taken for the key factor in R&D work to improve the efficacy in CNT-FED technology. © Akadémiai Kiadó, Budapest, Hungary 2009.

Indoor air quality is affected by volatile organic compound (VOC) pollutants and these are often emitted by furniture and building materials. To enhance indoor air quality, removing VOCs from indoor environment is an important task. Triethylene glycol (TEG) solution was used as working solution to absorb VOCs from ambient air in this study. Plastic 5/8 in. polaring-type was packed in the packed-bed absorber, and the packed length was about 34 cm. Toluene, methanol, ethyl ether, and methyl-ethyl ketone were absorbed separately by TEG solution. Two-level factorial experimental design methodology was applied to schedule the operating variables in the experiment. The advantage of experimental design methodology is to obtain reasonable experimental results with fewer experimental runs. In addition, the analysis of variance (ANOVA) was used to analyze the effect of operating variables (factors) on mass transfer coefficient (response). The p-value was used to assess the mass transfer performance of VOCs absorbed by packed-bed absorber. From experimental results, effect of air flux on mass transfer coefficient was significant except for methanol because the p-values were smaller than 0.1 for toluene, ethyl ether, and ketone. For VOCs concentration, the effect of methanol concentration on mass transfer coefficient was extremely significant; the effect of concentration of ethyl ether was very significant; the effect of concentration of toluene was significant; the effect of methyl-ethyl ketone was insignificant. Since all the p-values were smaller than 0.01 for liquid flux, the effect of liquid flux on mass transfer coefficient was very significant. By analyzing the factorial interaction, the factorial couples, toluene concentration × liquid flux, TEG concentration × methanol concentration, TEG concentration × ethyl ether concentration, and ketone concentration × liquid flux can be chosen as main variables to operate the absorption system for absorption of toluene, methanol, ethyl ether, and ketone to acquire the desired mass transfer coefficient. © 2009 Elsevier B.V.

Taiwanese culture is diverse, rich and sophisticated. After a long-term accumulation, it also has acquired solid cultural capacity. In the meantime, in recent years, the government has actively promoted policies on the cultural and creative industry, which has stimulated the developmental trends of creative industries and created new opportunities for many cultural and creative products. As a result, it has brought a lot of negative phenomena of “cultural industry” to Taiwan. Consequently, the initially good intention of the government in promoting the cultural and creative industry has eroded away the subjectivity and creativity of culture. Therefore, the purpose of this study is to explore and find the balance between two aspects – “commercialization” and “preservation of the spirit of cultural connotation” – in the process of developing cultural and creative products. Through case studies and fieldwork survey, this study performed analysis based on observations of special cultural activities and sceneries in Taiwan. Questionnaires were designed through the three-level theory of cultural coding. Design patterns and indicators of cultural and creative products were formulated based on visitors’ feedbacks and will be provided as a basis of reference for future designers of cultural and creative products. There are three findings obtained from this study: (1) High degree of correlation between cultural and creative product designs and cultural activities is fundamental and will create a memory connection with the products in a consumer’s brain. (2) Experiential models and handmade designs can enhance consumers’ understanding of culture. (3) Through the three-level theory of model design – integrated thinking of the strategic level, the connotative level, and the technical level – cultural products can effectively deliver cultural messages to consumers and at the same time create cultural styles. © Springer International Publishing Switzerland 2016.

Packaging plays a role of protecting the product, attracting consumers' attention, and communicating the product's contents. Logo typography is the most important written information of packaging. Among the packaging forms of commodities in the market, cylindrical packaging is in the majority. In the condition that the commodities are highly homogenous, packaging design has become an important factor in marking their difference. For example, changing the arched surface of cylindrical packaging is one of the feasible schemes. However, will different arched surface designs in cylindrical packaging with varied font features affect consumers' findability of the commodity? We investigated performance of the seven font features of logo typography combined with seven types of arched surface by means of experiment. The results of this study are as follows: (a) Interaction occurs between arched surface with different proportions and varied font features. (b) When logo typography is on the arched surface of a cylinder that has a ratio of horizontal axis to vertical axis between [3:5] and [2:5], varied font features will make significant difference in findability. (c) When the arched surface is greater (i.e. the ratio will become smaller, e.g., [2:5]), the oblong typography is superior to square typography ([Balloon Bd BT (e.g., )]). (d) Optimum findability and discerning performance are achieved when the font feature used is a sans serif structure with equal strokes in thickness, according to the design principle of logo typography. If logo typography is put on the arched surface of an outstanding cylinder (when the visible arched surface is narrower), the fonts with strokes and structure like Script should be avoided as much as possible to keep off low findability. © 2010 Elsevier B.V.

A system is subject to shocks that arrive according to a non-homogeneous Poisson process. As shocks occur, the system has two types of failures: type 1 failure (minor failure) is removed by a minimal repair, whereas type 2 failure (catastrophic failure) is removed by overhaul or replacement. The cost of minimal repair depends on age. A system is overhauled when the occurrence of a type 2 failure or at age T, whichever occurs first. At the N-th overhaul, the system is replaced rather than overhauled. A maintenance policy for determining optimal number of overhauls and optimal interval between overhauls which incorporate minimal repairs, overhauls and replacement is proposed. Under such a policy, an approach which using the concept of virtual age is adopted. It is shown that there exists a unique optimal policy which minimises the expected cost rate under certain conditions. Various cases are considered. © 2012 Taylor and Francis Group, LLC.

It is generally believed that the same piece of music, after a change of melody or associated instrument, could often elicit a different emotion, thus resulting in a change of music style. However, so far there have been rarely systematic studies on the relationships among the tunes, instruments, and aroused feelings. This paper proposes a framework to perform an automatic style conversion for the music represented in a MIDI format. Compared with most existing tools for music compositions where a professional background is usually assumed, we aim to provide a user-friendly system such that, with simply a mouse click, a desired music style transformation could be achieved by automatically adjusting the associated tempo and instruments of the music. Numerous music styles have been tested and results are quite satisfactory. We believe such a framework could be standardized and adopted in nowadays portable devices, such as laptops, tablet PCs, PDA, or smart phones. © (2013) Trans Tech Publications, Switzerland.

The mass transfer performance is usually affected by the wetting of the packing surface with absorbent solution, and the wetted surface can be affected by interfacial disturbances resulting from the gradient in surface tension between water vapor and absorbent solution. In order to discuss the effects of interfacial phenomena on mass transfer performance of water vapor absorbed by triethylene glycol (TEG) and lithium bromide (LiBr) solutions, an absorber packed closely with cylindrical packing was designed in this study and the packing material was polyvinyl chloride. In addition, the interfacial behaviors were observed from water droplet positioned on the surface of absorbent solution, and the surface stress was defined and calculated to analyze how mass transfer performance was affected by the stress. Experimental results show that surface stress increases with increases in concentration of TEG solution. The surface stress increases significantly when the concentration of TEG solution exceeds 92. wt.% The area of packing wetted by TEG solution increases as the concentration of TEG solution and humidity increase. Therefore, the mass transfer performance also increases with the higher concentration and higher humidity. © 2013 Elsevier B.V.

School emblems express the spirit of the school, winning a sense of identification from teachers and students. We wonder if the imagery conveyed by school emblems is in agreement with how viewers feel. The following is a summary of our research results: (1) The horizontal axis in the imagery space is "fond - hateful"; the vertical axis is "concrete - abstract". School emblems are distributed in the space between the two axes. (2) The influences on imagery are simplified into four factors. The four factors, arranged in the order of importance, are "psychology", "shape", "times" and "strength". (3) In the design of school emblems, "circular", "club-shaped" and the like are more popular in Taiwan. In contrast, irregular forms are less welcomed and should be avoided when making emblems. (4) To give a sense of entirety, school emblems have to be closed figures. Circular and square emblems, in particular, have better completeness. © 2011 Springer-Verlag.

In order to investigate the mass transfer phenomenon of the absorption of water vapor in desiccant solutions, a system of absorption cell was designed. The gradient in surface tension can result from the contact process between the desiccant solution and water vapor. This induced interfacial disturbance will affect the mass transfer performance. The experimental results demonstrate that the theoretical mass transfer coefficients predicted by boundary layer theory are less than those of the experimental values. In addition, the mass transfer performance of the absorption system can be enhanced by adding ethanol to the absorbent solutions. In order to describe the level of mass transfer performance affected by the interfacial convection resulting from the addition of ethanol, the enhancement factor was defined in this study. The enhancement factor is from 1.26 to 1.56 for adding ethanol to DEG (diethylene glycol) solution, and from 1.36 to 1.61 for adding ethanol to TEG (triethylene glycol) solution. © 2014 Copyright Taylor & Francis Group, LLC.
