Logo has influenced many researchers and learners for the past decades as a 20 turtle geometry environment in the perspective of constructionism. Logo uses the metaphor of 'playing turtle' that is intrinsic, local and procedural. We, then, design an environment in which the metaphor of 'playing turtle' is applied to construct 3D objects, and we figure out ways to represent 3D objects in terms action symbols and 3D building blocks. For this purpose, design three kinds of representation systems, and asked students make various 3D artifacts using various representation systems. We briefly introduce the results of our investigation into students' cognitive burden when they use those representation systems, and discuss the future application measures and the design principles of Logo-based 3D microworld.

Papert [17] introduced the LOGO environment in which we make a curve using LOGO commands (FORWARD, ROTATE). We call this geometry as turtle geometry. This environment has influenced many researchers and designers of computers and mathematics education. But the curve that we can make using LOGO command is elementary or too difficult. Polygon and circle is elementary and making other curves is difficult. In this paper, we introduce the method of drawing some other curves mediating new command. First, we study epicycloid and hypocycloid in the historical and the physical context. And we introduce the method of making epicycloid and hypocycloid using vector addition. Next we study the polygon patterns of this curve. Finally, we extend the method for making more general curve and we improve the computer environment using this metaphor.

Vehicle-logo recognition technology is very important in vehicle automatic recognition technique. The intended application is automatic recognition of vehicle type for secure access and traffic monitoring applications, a problem not hitherto considered at such a level of accuracy. Vehicle-logo recognition can improve Vehicle type recognition accuracy. So in this paper, introduces how to vehicle-logo recognition. First introduces the region of the license plate by algorithm and roughly located the region of car emblem based on the relationship of license plate and car emblem. Then located the car emblem with precision by the distance of Hausdorff. On the base, processing the region by morphologic, edge detection, analysis of connectivity and pick up the PCA character by lowing the dimension of the image and unifying the PCA character. At last the logo can be recognized using the algorithm of support vector machine. Experimental results show the effectiveness of the proposed method.

This paper analyses the sensory responses of Chinese female consumers towards different designs of perfume bottles with particular attention to the existence of logos on them. We used total 40 samples of the perfume bottles, 20 with logos on them and 20 without, and the results show that young Chinese female consumers prefer simple designs over complex designs that contain different types of free curves with vivid colors. In addition, the existence of logos on bottles was found not to change the responses significantly, meaning that the logos on bottles do not affect sensibility of Chinese female towards perfume bottles. A logo's impacts on the bottle depended in part on the bottle's color and shape. Overall, a perfume bottle with simple shapes and light colors became regarded as more resplendent when the logo was added, but a bottle with more complex shapes and vivid colors tended to become regarded as plainer after adding the logo. This shows that a logo serves as a conciliatory element in the impression of the whole bottle in the 'resplendent-plain' category.

Modern University students easily experience identity turmoil. The purpose of this study is to explore the process of recovery of univercity student who lose the meaning of life and feel depressed and lethargic by Logo-therapy, and to seek therapeutic use in counseling. As a result of the analysis, Loss of meaning and confusion in life, Expressing the will to pursue meaning, Meaning of life recovery and re-implication, 3 categories and 10 subcategories were derived. Through other Qualitative research. I hope that more results will show that Logo-therapy restores the meaning of life to university students. It can be used as therapeutic data to seek university student's meaning of life by Logo therapy.

This study suggests a suitable logo design application of a three colors LED light source and flexible plastic optical fiber (POF). In this study, characteristic relevant brightness of (according to the embodiment conditions of the flexible POF for logo design) for smart clothing were analyzed through two experiments. The suitable conditions of the logo design for three colors of light source were observed in 'Experiment 1'. The angle of $80^{\circ}$ to $100^{\circ}$ and the length of 8cm to 16cm appeared a more suitable condition for green-colored and red-colored light sources. The angle of $80^{\circ}$ to $100^{\circ}$ at a length of 8cm to 12cm appeared a more suitable condition for a blue-colored light source. In 'Experiment 2', a 'Klavika' in small letter was selected as suitable logo design for the application POF. The alphabet was separated by a morpheme, which is the minimal linguistic unit. All alphabets were classified into sixteen morphemes. The luminance of fourteen morphemes (realized by the embroidery method) were measured and analyzed. Subsequently, eight morphemes appeared to show a relatively equal luminance of $3-4cd/m^2$ in a green-colored light source, $2-3cd/m^2$ in red-colored light source, and $2cd/m^2$ in a blue-colored light source. Four of the fourteen morphemes, showed a 20% brighter level of luminance compared to the eight morphemes above, the cast of combination of green or red light source. This result indicates that a flexible POF with 20% less luminance are believed more suitable for four morphemes combined with a green or red light source. The results of this study provide fundamental data for further approaches to clothing logo design for the application of a flexible POF.

As the postsecondary school-age population continues to decline, universities are building identities to differentiate themselves and create a favorable impression among this cohort. We investigated the role of logo-bearing products as a way of promoting university identity, specifically, the effects of ingroup ties, ingroup affect, and centrality on attitude toward university logo products and purchase intention. This study further examined the moderating effects of perceived university prestige on the relationship between logo product attitude and in-store purchase intention, and the moderating effect of online shopping frequency on the relationship between logo product attitude and online purchase intention. We conducted a survey of undergraduate and graduate students at a university in Seoul. Survey responses (N=561) were collected and processed using SPSS 23.0. Multiple regression analysis showed that ingroup ties and affect had significant effects on product attitude. However, centrality had no significant effect on attitude toward the product. Product attitude had a direct significant effect on both in-store and online purchase intention. Perceived university prestige moderated the relationship between product attitude and in-store purchase intention. Moreover, online shopping frequency moderated the relationship between product attitude and online purchase intention. The results of this study are expected to provide fundamental knowledge for developing product strategy of logo products.

In this paper, we proposed a personal identification method using binay image encryption technique and decryption system in JTC structure. Logo which represents the group symbol was encrypted with personal fingerprint and JTC structure decrypts this logo. The logo can not decrypted by other unused fingerprint even if the encrypted image was lost or stolen. So this method can give more safe personal identification.

The purpose of this study was to investigate whether the experience of computer programming in Logo geometry advances the development of young children's concepts and/or representation of Euclidian spatial relations, particularly their concepts of the vertical-horizontal. Papert's claim of the positive effects of Logo programming experiences on young children's cognitive development was tested using the Piagetian Water Level Test (PWLT), the Free Hand Drawing Test (FHDT), and the Computer Drawing Test (CDT). Forty-four subjects were drawn from 2nd graders attending a public elementary school in Ithaca. The subjects were divided into 2 groups: a treatment group (TG) with Logo training for 10 weeks and a control group (CG) without Logo training. Our results showed that TG did not make any significant improvement on PWLT. In contrast, TG outperformed CG on FHDT. We suggested several possible explanations for this contradiction.
