Brand personality is the human-like traits of brands that consumers can use to identify brands. Despite the importance of brand personality, there has been limited research about it in Korea recently, especially for casual apparel brands. Considering the changes in lifestyle and the increasing popularity of leasure activities in Korea, it is important to analyze the brand personality of casual brands for understanding Korean consumers. This study aimed to analyze the brand personalities of eight well-known casual brands in Korea, and to investigate the relationship between the brand personalities and brand preference. Specifically, this study questioned whether the similarity in brand personalities leads to similar patterns of preference for the brands. The eight brands were carefully selected so that they can well represent the diversity in the dimensions of perceived brand personality, while also being well-known to the participants of the survey. Factor analysis of the data from the survey of Korean university students yielded five factors of brand personality: liveliness, high class, ordinariness, rationality, and reliability. The eight brands showed significant difference across the five factors. Multidimensional scaling analyses of the brands were conducted based on the similarity in brand personality and brand preference respectively. The result showed significant difference in the relative distribution of the eight brands in the two-dimensional space of the analyses.

Nowadays the preschool children spend much of the day playing indoors. Therefore, it needs the indoor environment that helps a variety of fun activities and physical development, and it requires the space configuration and playable furniture considering the emotional development for mental health. However, the furniture for fast growing preschoolers has not various types because the domestic furniture market for children is mostly baby beds and the furniture for the education of children. Therefore, this study presents the concepts and types of the playable furniture reflecting emotional design for preschool children's healthy emotion and suggests the most appropriate type of playable furniture considering play behavior by age. In this study, we investigated the physical, cognitive, social, emotional and linguistic development characteristics and play behavior of preschoolers, and derived the right type of playground equipment and furniture, and examined the types of playable furniture to help the emotional development. We derived the items to be checked for developing the playable furniture by age for emotional development, and classified preschoolers' playable furniture into the use of learning, relaxation and storage, and suggested its basic type focusing on the cases of various playable furniture developed at home and abroad. As a result, the playable furniture was divided into three types. The first is the self-play type making possible self amusement, the second is module built-up-type that consists of furniture and modules or units and creates various patterns and can be modified through the self-assembly and disassembly, and the third is IT game type grafting IT skills and a variety of electronic games to furniture. We sorted these types into three classes (1-3 years old, 4-5, 6-7) according to age and presented the type of play for each age, the play element and representative image that can be introduced to this furniture. In this study, we provided the basic design types of age-specific emotional playable furniture by analyzing these results.

The aims of this research were to characterize magic realism by analyzing existing magical reality literature reviews and research and to identify material that may inspire ideas for stage and film costume design by analyzing and drawing design characteristics and magic realism of costumes from Director Tarsem Singh's movie, 'Mirror, Mirror'. For the methodology, characteristics of magic realism in literature and, movies were analyzed, with a theoretical consideration of these materials on magical realism. Data on costume design and magical realism characteristics for use in the analysis were collected from the main characters of 'Mirror, Mirror' as well as from other characters. The result of this analysis was the emergence of five common characteristics of the magic realism Historicity, the most remarkable characteristic seen in Tarsem Singh films, was expressed through the symbolic meaning and decorative patterns shown by the traditional-style costumes, colors. Symbolization was expressed through the symbolic meaning, decorative elements, and traditional clothes, as shown by the colors and forms of the costumes. Fantasy was expressed through the colors, decorative elements, forms of traditional clothing, and forms with symbolic meaning. Reproducibility was expressed through the method of decorative element, symbolic meaning, traditional forms and de-structural clothes. Ambiguity, which can be associated with the combined characteristics of historicity and fantasy, was expressed in the clothes worn in the scenes that confounded time and space within the film.

Tooth impaction may lead to malocclusion, root resolution, cyst or aberrant changes in adjacent teeth. Clinical and radiographic examinations are used to locate the impaction, and appropriate treatment plans must be made to relocate the impacted tooth. When surgically exposing the impacted tooth, periodontal considerations to conserve maximum amount of soft and hard tissue are used. Oral hygiene instructions are emphasized to maintain sound periodontal health. Securing enough space for the impacted tooth and proper anchorage is important. Proper use of force and mechanics is crucial to prevent such complications as root resolution. Various patterns of orthodontic traction may be employed as situation permits. Most impaction cases can be managed with orthodontic traction to restore function and esthetics, provided that early detection and proper diagnosis and treatment planning are made.

This paper proposes a new type of a dual-band internal antenna for GPS/PCS handsets. The antenna has three monopoles in different lengths, and this structure is referred as a 3-fingers type antenna in this paper. The antenna with low-profile structure is designed to use internal space of handset maximally. The fabrication and the measurement are accomplished by attaching the 3-finger type antenna to the inside of a commercial handset. We obtain gain of 1.97 dBi$\~$0.66 dBi in the GPS band, and -0.92 dBi$\~$1.02 dBi in the PCS band and almost omni-directional patterns at all bands.

This study collects social big data used in various fields in the past 9 years and explains the patterns of major keywords of the arboretums and botanical gardens to use as the basic data to establish operational strategies for future arboretums and botanical gardens. A total of 6,245,278 cases of data were collected: 4,250,583 from blogs (68.1%), 1,843,677 from online cafes (29.5%), and 151,018 from knowledge search engine (2.4%). As a result of refining valid data, 1,223,162 cases were selected for analysis. We came up with keywords through big data, and used big data program Textom to derive keywords of arboretums and botanical gardens using text mining analysis. As a result, we identified keywords such as 'travel', 'picnic', 'children', 'festival', 'experience', 'Garden of Morning Calm', 'program', 'recreation forest', 'healing', and 'museum'. As a result of keyword analysis, we found that keywords such as 'healing', 'tree', 'experience', 'garden', and 'Garden of Morning Calm' received high public interest. We conducted word cloud analysis by extracting keywords with high frequency in total 6,245,278 titles on social media. The results showed that arboretums and botanical gardens were perceived as spaces for relaxation and leisure such as 'travel', 'picnic' and 'recreation', and that people had high interest in educational aspects with keywords such as 'experience' and 'field trip'. The demand for rest and leisure space, education, and things to see and enjoy in arboretums and botanical gardens increased than in the past. Therefore, there must be differentiation and specialization strategies such as plant collection strategies, exhibition planning and programs in establishing future operation strategies.

In this paper, review was made for the excavation method and optimum bench length for unstable tunnel face in case of rock classification type V in order to make the best use of in-situ bearing capacity. 3D FEM analyses were performed to investigate the influences on the tunnel face and adjacent area with regard to the pattern and number of bolts when face bolts were used as a supplementary measure. As a result of this study, full section excavation method with sub-bench is effective in reducing the displacement greatly due to early section closure. Displacement-resistant effects in accordance with the bolting patterns are grid type, zig-zag type and then circular type in order of their effect. And horizontal extrusion displacement of tunnel face reduces as the number of bolts increase. A grid type face bolt covering $1.5m^2$ of tunnel face could secure the face stability in case of full section excavation method with sub-bench.

Due to the expansion of cyber space, war patterns are also changing from traditional warfare to cyber warfare. Cyber warfare is the use of computer technology to disrupt the activities of nations and organizations, especially in the defense sector. However, the defense against effective cyber threat environment is inadequate. To complement this, a new cyber warfare operation concept is needed. In this paper, we study the concepts of cyber intelligence surveillance reconnaissance, active defense and response, combat damage assessment, and command control in order to carry out cyber operations effectively. In addition, this paper proposes the concept of cyber warfare operation that can achieve a continuous strategic advantage in cyber battlefield.

It was already realized at a current technological level of home network systems that the systems recognizes a user's simple order and carry out the order in the ubiquitous computing environment. However home is not a simple environment consisting into a large number of family members, so various order and situation would be needed accordingly. From now on we need to reach the technological level to infer that how is the user's behavior patterns and what kinds of service is the fittest to user who belong to the ubiquitous computing environment by using the result of the context interpreter. In this regards, active inferred-model needs to be suggested upgrading user's command into one step more higher level than the simple one adapting diversified feature. This study would like to suggest this active model recognizing context, which is user's environmental information applying basic network and inferring Context-based Service that user wants through the recognized result This study proposes a new method that can infer the user's desire in ubiquitous computing environment. First of all, we define a context as user's information of ubiquitous computing environment situation that user belongs to and we classify the context into 4W1H(Where, Who, When, What) formats. We construct Bayesian network and put the factor of context use as Bayesian network nodes. As a result, we can infer the user's behavior pattern and most proper service for user in the intelligent space from the probabilistic result of Bayesian network.

In this paper, we propose a novel fingerprint classification method to enhance the accuracy and efficiency of the fingerprint identification system, one of biometrics systems. According to the previous researches, fingerprints can be categorized into the several patterns based on their pattern of ridges and valleys. After construction of fingerprint database based on their patters, fingerprint classification approach can help to accelerate the fingerprint recognition. The reason is that classification methods reduce the size of the search space to the fingerprints of the same category before matching. First, we suggest a method to extract region of interest (ROI) which have real information about fingerprint from the image. And then we propose a feature extraction method which combines gray level co-occurrence matrix (GLCM) and wavelet features. Finally, we compare the performance of our proposed method with the existing method which use only GLCM as the feature of fingerprint by using the multi-layer perceptron and support vector machine.
