Typically users prefer to manage and access personal photo collections taken from a cell phone based on events. In this paper we propose an event clustering algorithm that requires low computation cost with high accuracy supporting incremental operation. The proposed method is based on the statistical analysis of the elapsed interval of intra-event photos on the real sample data for the decision of an event boundary. We then incorporate both location and visual information for the ambiguous range to split with only temporal cue. According to test results, we show higher performance compared to existing general clustering approaches.

In this study, an equation for modelling the shear strength of reinforced concrete member with web reinforcement is proposed. Although the general formulas for shear strength of reinforced concrete member with small a /d are obtained based on the experimental results, the proposed equation herein is derived from lower bound theorem of limit analysis. The proposed model takes into account arch mechanism and truss mechanism. And ir provides the values of divided shear strength ratio of each mechanism as well as visual understanding of the mechanism on how the given load is transfered to the support. Also, the model takes into account the effect of a /d. longitudinal reinforcement ratio, and web reiriforcement ratio quantitively. Based on the comparisons of the result of this model with previous, test results, it shows good agreements.

Since the twentieth century, common exhibitions have experienced display replacements and apace alterations. As a result, not only the visual space background of the spectators but the structure systems and positions of the construction space have also been changed. With regards to common zones of the exhibition space, appropriate harmonization of spectators space, aisle space, and media space are closely related the effectiveness and propriety of display arrangement. A number of preceeding researches suggest exhibition first, construction next, regarding the order of the construction and exhibition of the museums and art galleries. However, a majority of the exhibition hall constructions in Korea have not been carried away based on these models. Thus, disharmony of constructions and exhibition space structures have caused numerous problems. The purpose of this research is to seek the countermeasures that can be used in the stage of planning for the museum constructions and exhibition space by suggesting, based on the above mentioned points, the development of the indicators and analyzing methods to understand the structural attributes of the common exhibition space through space syntax method and multivariate analysis.

The numerical analysis indicated that the vibration response reduced sharply at the three times of tunnel diameter. Visual display of vibration response was possible through 3-D FEM computer program, and displacement of structure, particle velocity were obtained as output. It was found that the vibration velocity was maximum at distance one to two times of tunnel diameter for the given simplified blast loadings. The results of numerical analysis were compared with empirical based predictive equation of blasting. The empirical equation showed a good agreement with 3-D FEM results at a certain range of tunnel depth in this particular type of ground conditions.

Purpose. To analysis the refractive error in 7-9 year-old Korea children. Methods. From July 2013 to June 2014, two hundred eighty two subjects were performed in refraction test using the Auto-Refractometry. Results. The refractive error by spherical equivalent among all subjects was myopia 47.58%, emmetropia 42.35%, astigmatism 32.33%, and hyperopia 8.76%. Myopia was more common in female than males although the difference was not statically significant. The axis of astigmatism was with the rule in 65%, against the rule in 31.5%, and oblique in 3.5% There was a statistical significance between 7 year and 9 year of male in the spherical equivalent power(p=0.010). Also there was a statistical significance between 7 years and 9 years of female in the spherical equivalent power(p=0.036). However, there was not a statistical significance between male and female in spherical equivalent power(p>0.5). Conclusions. In this study, myopia was the most common refractive error. On the other hand, The prevalence of the axis of astigmatism was the with- the- rule. The spherical equivalent of refractive error was similar results between male and female. However The refractive error was different style with aging. these data suggested that the analysis of the refractive error at young children can provide the information of useful diagnosis for the correction of visual acuity.

This study is intended to suggest an improvement scheme of activating container multiplex cultural space through an analysis of container architecture characteristics and a survey of user satisfaction, focusing on container multiplex cultural space located in Seoul city. Hence, the elements of multiplex cultural space and the characteristics of container architecture were deduced and analyzed through precedent study and literature review relating to multiplex cultural space and container architecture, and then an analysis framework was established with items to measure the user satisfaction. Based on this, a questionnaire was created, and users were surveyed through on-site visit. The results of analyzing the container multiplex cultural space users' satisfaction are as follows. First, in order to increase user satisfaction, it is necessary to highlight visual element. Second, there is necessity for distinct space configuration, such as connection, stack and extension by utilizing the fixed specifications, the characteristics of container. Third, there is necessity for extended space where people feel a sense of openness. Fourth, it should be improved so that air is well circulated by installing glass, operable window, etc. In further research, it is thought necessary to make a study of commercial space and facilities inside university besides multiplex cultural space.

Recently, cosmetic shops are facing a complicate economy situation and a great number of brands are attempting two-way communication with customers, not one-way communication. 'Brand' equity is important to deliver virtual brand mark as visual image. We have 4 steps for brand identity structure, and this study is about the first 'brand-awareness' and the second step 'brand-image'. We investigated the correlation between brand-awareness and brand-image after searching which spatial elements are highly effective to both steps as we designated 5 cosmetic shops. We already organized the means of spatial analysis and we separated into two elements, constructive and decorative. For constructive element, a shop needs a distinct ceiling and wall design, and for decorative element, strong brand image communication is required through showcase design. We proved that brand awareness and brand image have the correlation, which also can be in direct proportion, by regression analysis. The result of this study shows that improving brand awareness as the primary element for cosmetic road shop can be an effective way to enhance brand image.

The income level of people in South Korea has risen as the gross national income per capita reached the milestone of 30,000 dollars. More and more consumers try to change their houses according to their tastes just like they express themselves through clothes, bags, and other fashion items, thus pursuing value-based consumption. The changes to the housing culture including the greater percentage of one- or two-person households and the growing trend of lease and monthly rent have made consumers increase their demands for products to express their lifestyles. As a result, global lifestyle shops with characteristic and diverse concepts entered the South Korean market and were joined by South Korean fashion brands, large-sized stores, department stores, and fancy stationery manufacturers, which launched their own brands, in the expansion of lifestyle shops across the nation. Lifestyle shops have a couple of unique attributes including the relatively clear selection of target consumers and a clear set of VMD strategies accordingly. Based on a judgment that there was cost differentiation among brands, the investigator categorized the comparison and analysis criteria into high, middle, and low prices to apply case analysis. This study set out to analyze VMD strategies for spatial composition through cost differentiation among lifestyle shops, take the results into total consideration, and propose an effective and competitive VMD strategy for lifestyle shops through spatial composition elements.

PURPOSE: This study was conducted to investigate the characteristics of a specific functional shoe in terms of the range of motion (ROM) of ankle and foot joints during walking when compared to a standardized shoe. METHODS: Kinematic ROM data pertaining to ankle, tarsometatarsal, and metatarsophalangeal joints were collected from twenty-six healthy individuals during walking using a ten-camera motion analysis system. Kinematic ROM of each joint in three planes was obtained over ten walking trials consisting of two different shoe conditions. Visual3D motion analysis was finally used to coordinate the kinematic data. All kinematic ROM data were interpolated using a cubic spline algorithm and low-pass filtered with a cutoff frequency of 6 Hz for smoothing. RESULTS: The overall ROM of the ankle joint in the sagittal and coronal planes when wearing the specific functional shoe was significantly decreased in both ankles during walking when compared to wearing a standard shoe (p<.05). Significantly more flexibility was observed when wearing the specific functional shoe in the tarsometatarsal and metatarsophalangeal joints compared to a standard shoe (p<.05). CONCLUSION: Although clinical application of the specific functional shoe has shown clear positive effects on knee and ankle moments, the results of this study provide important background information regarding the kinematic mechanisms of these effects.

In this paper, we investigate the co-movements of the real GDP cycle and the telecommunications service expenditure cycle over 1980 through 2000 in Korea. We used several appropriate statistical tools to characterize and to compare the co-movements between the two aforementioned variables. The statistics presented in this paper are common, easy to Interpret and capture important visual, descriptive information and the dynamics of data that would be lost if one focused only on the unconditional correlation coefficients of de-trended data. This paper examines four possible characteristics for the co-movements of real GDP and telecommunications service expenditure in Korea. The first is that in low frequency, the cyclical movements in telecommunications service expenditure are very similar to the cyclical movements in real GDP, The second is that in the high frequency, the estimated stationary cyclical telecommunications service expenditure is not closely related to the estimated stationary cyclical real GDP. Third, according to co-spectra analysis, the strong relationships between the variables are found in the mid-term frequency and as such this empirical finding has important implications for telecommunications policy and telecommunications service implementation strategies. Finally, in the short-term period, our empirical results support telecommunications network theories such as path dependence properties, lock-in, positive feedback externality, and network externality.
