In recent years, young Chinese consumers have become more favorably inclined toward products relating to traditional culture. Therefore, this study aimed to develop a textile design that incorporates traditional Chinese patterns and cultural symbolism that will appeal to consumers from the MZ generation (millennials and Generation Z). Through a literature search for traditional Chinese patterns and symbols regarded as auspicious, our design concept and motives were established. We selected peony, lotus, and frog motifs as representative of a "wealth and eternal prosperity" design theme. In textile design work 1, we used hand drawing and watercolor techniques, color transformation with Adobe Photoshop, and colorway and end-use 3D simulation with TexPro. The 3D simulation work suggests that this textile pattern is suitable for women's outerwear, mufflers, and tote bags. Textile design work 2 conveyed the 'wealth and eternal prosperity' design theme and had a graceful mood that embodied the nobility of the lotus flower whilst also encompassing the symbolism of money and status. The end design is a modern reinterpretation of traditional Chinese patterns and motifs. As such, it is hoped that it will satisfy the needs of young consumers for cultural values yet offer a unique new aesthetic distinct from existing textile designs. These qualities can be expected to enhance the competitive market value of textiles bearing this design.

In this paper, we design a perceptually invisible dot pattern layout and its recognition scheme, and we apply the recognition scheme into a smart self learning aid for interactive learning aid. To increase maximum information capacity and also increase robustness to the noises, we design a ECC (error correcting code) based dot pattern with directional vector indicator. To make a smart self-learning aid, we embed the micro dot pattern (20 information bit + 15 ECC bits + 9 layout information bit) using K ink (CMYK) and extract the dot pattern using IR (infrared) LED and IR filter based camera, which is embedded in the smart pen. The reason we use K ink is that K ink is a carbon based ink in nature, and carbon is easily recognized with IR even without light. After acquiring IR camera images for the dot patterns, we perform layout adjustment using the 9 layout information bit, and extract 20 information bits from 35 data bits which is composed of 20 information bits and 15 ECC bits. To embed and extract information bits, we use topology based dot pattern recognition scheme which is robust to geometric distortion which is very usual in camera based recognition scheme. Topology based pattern recognition traces next information bit symbols using topological distance measurement from the pivot information bit. We implemented and experimented with sample patterns, and it shows that we can achieve almost 99% recognition for our embedding patterns.

The logistic environment of Korean companies faces very challenging circumstances due to lack of resources and tough price competitions. It is obvious that such a load of logistic cost becomes an obstacle to national or business competition advantages in the era of unlimited market competition. Prior studies concerning these issues sought to express a large-scale distribution network in a unified numerical formula using defined symbols and could take systematic approaches to distribution network. But inventory policy and operation in material distribution system have been limited to conventional methodology. so they are exposed to many questions in practical applications. This study analyzed distribution system cost and developed a relevant model for operation policy of distribution system for the efficeient treating of stockout. allowing practical applications, so that it will contribute to saving operational cost related to material distribution system.

As the computer technology is developed, score-writers that can edit music have more improved functions. A user not only can insert notes, chords, and musical symbols conveniently, but also can listen to music displayed in the score. Existing commercial score-writers make scores look good and play notes through VSTi(Virtual Studio Technology instrument). However chord accompaniment function is so vulnerable that it is hard to know whether or not displayed chords are suitable for music. If a score-writer has a proper function that plays chord sound good to hear, it will be a good reference to band music sheet writers. In this paper, to improve chord playback function in existing score-writers, we propose an algorithm that selects suitable chord tones for chord playback and implemented a program. If we apply this algorithm, the chord play function of a score-writer will be strengthened and resultantly a music sheet writer who makes a band music can make scores more conveniently.

Character encoding is the method used to represent characters or symbols on a computer, and there are many encoding detection software tools. For the widely used encoding detection software"uchardet", the accuracy of encoding detection of unmodified normal text document is 91.39%, but the accuracy of language detection is only 32.09%. Also, if a text document is encrypted by substitution, the accuracy of encoding detection is 3.55% and the accuracy of language detection is 0.06%. Therefore, in this paper, we propose encoding and language detection of text document using the deep learning algorithm called LSTM(Long Short-Term Memory). The results of LSTM are better than encoding detection software"uchardet". The accuracy of encoding detection of normal text document using the LSTM is 99.89% and the accuracy of language detection is 99.92%. Also, if a text document is encrypted by substitution, the accuracy of encoding detection is 99.26%, the accuracy of language detection is 99.77%.

In this study, the symbols and visual expressions employed in the food culture content of official website designed to promote three cities in Korea, Seoul, Jeonju and Jeju, were subjected to semiotic analysis. In this study, it was assumed that these websites reflected the varying perspectives of the people behind the development and management of these routes of Internet communication, and the semiotic choices made in order to exemplify each city's food cultural image. The aim of the study was to analyze the communication strategies of food cultural branding in the terms of the online content regarding Seoul, Jeonju, and Jeju with a focus on the comparative points in these cities' official websites. This study included conducting semiotic content analyses of the aforementioned cities' official web pages in an attempt to determine the food branding strategies used to differentiation and produce more favorable perceptions of these three cities. Building upon the findings drawn from this comparative study, the present work can be used to determine more effective ways of strategically differentiating the images of local food culture associated with these cities from the view of brand communications. This study also demonstrates viable directions for designing web content for a city where the food cultural messages can be delivered in a thoughtful and effective manner.

This paper examines the ink on paper technique that is being used in the animation works by the Canadian filmmaker Michēle Cournoyner from the National Film Board of Canada. It also discusses how in her animated film "Soif"(2013) this technique has been applied to compose the narrative significance and symbols through the use of metamorphosis as a form of artistic expression. Cournoyner had used the ink of paper technique as a means to abandon realistic representations of movement, and in "Soif" through expressive use of metamorphosis, portrayed changes of images in character and object not through chronological order of narrative flow, but through the body of the female character, which had been represented by the improvisation of the ink on paper technique in order to express the surrealistic and unconscious state of mind in animation. Also, the use of Surrealist automatism had been incorporated to evoke the film towards a form of abstract and metaphysical expression, which in terms of expression and technique connects with the character in the animation to give emphasis to its relevancy with the subject matter of the work.

This study investigated fifth graders' understanding of variables from a generalized arithmetic and a functional perspectives of early algebra. Specifically, regarding a generalized perspective, we included the property of 1, the commutative property of addition, the associative property of multiplication, and a problem context with indeterminate quantities. Regarding the functional perspective, we covered additive, multiplicative, squaring, and linear relationships. A total of 246 students from 11 schools participated in this study. The results showed that most students could find specific values for variables and understood that equations involving variables could be rewritten using different symbols. However, they struggled to generalize problem situations involving indeterminate quantities to equations with variables. They also tended to think that variables used in representing the property of 1 and the commutative property of addition could only be natural numbers, and about 25% of the students thought that variables were fixed to a single number. Based on these findings, this paper suggests implications for elementary school students' understanding and teaching of variables.

High-rise structures are considered as symbols of economic power and leadership. Developing countries like India are also emerging as centers for new high-rise buildings (HRB). As the land is expensive and scarce everywhere, construction of tall buildings becomes the best solution to resolve the problem. But, as building's height increases, its stiffness reduces making it more susceptible to vibrations due to wind and earthquake forces. Several systems are available to control vibrations or deflections; however, outrigger systems are considered to be the most effective systems in improving lateral stiffness and overall stability of HRB. In this paper, a 42-storey RCC HRB is analyzed to determine the optimum position of outriggers of different materials. The linear static analysis of the building is performed with and without the provision of virtual outriggers of reinforced cement concrete (RCC) and pre-stressed concrete (PSC) at different storey levels by response spectrum method using finite element based Extended3D Analysis of building System (ETABS) software for determining responses viz. storey displacement, base shear and storey drift for individual models. The maximum allowable limit and percentage variations in earthquake responses are verified using the guidelines of Indian seismic codes. Results indicate that the outriggers contribute in significantly reducing the storey displacement and storey drift up to 28% and 20% respectively. Also, it is observed that the PSC outriggers are found to be more efficient over RCC outriggers. The optimum location of both types of outriggers is found to be at the mid height of building.
