  • Background: The MLA is supported by both the abductor hallucis (ABH) and the extrinsic muscles. Insufficient muscular support may lower the MLA when the body's weight is applied to the foot. The short foot exercise (SFE) is effective in increasing the height of the MLA for people with flat feet. Most of the research related to the SFE has simply evaluated the efficiency of the exercise using enhanced ABH electromyography (EMG) activation. Since the tibialis anterior (TA), peroneus longus (PER), and ABH are all involved in supporting the MLA, a new experiment design examining the EMG of the selected muscles during SFE should be applied to clarify its effect. Objects: Therefore, this study aimed to clarify the effect of the SFE in different ankle position on the MLA angle and the activation of both the intrinsic and extrinsic muscles and to determine the optimal position. Methods: 20 healthy subjects and 12 subjects with flat feet were recruited from Yonsei University. The surface EMG and camera were used to collect muscle activation amplitude of TA, PER, and ABH and to capture the image of MLA angle during SFE. The subjects performed the SFE while sitting in three different ankle positions-neutral (N), dorsiflexion (DF) at 30 degrees, and plantar flexion (PF) at 30 degrees. Results: ABH EMG amplitudes were significantly greater in N and DF than in PF (p<.05). Muscle activation ratio of TA to ABH was the lowest in PF (p<.05). MLA angle in both groups significantly decreased in PF (p<.01). The TA and ABH was activated at the highest level in DF. However, in PF, subjects significantly activated the ABH and PER with relatively low activation of TA. Conclusion: Therefore, researchers need to discuss which SFE condition most effectively use the arch support muscle for flat foot.

  • The Philippines was colonized by Spain for about centuries, from 1521 to 1898, and ruled by America for around four decades, from 1899 to 1946. After recovering from the Second World War, the government started to harness human labor as export itself. In the present time the overseas Filipinos keep the economy afloat with their steady transfer of money to relatives and dependents. Through the art works, the issue which Filipinos were exploited and exported by its government has been reflected as the various allegories. As Filipinos traditionally follow and keep Catholic belief, themes of Christ's sacrifice has allegorically been represented as salvation, struggle, suppression, and emancipation of people. Through the allegory, we can interpret both the intrinsic and superficial texts. Also we can identity certain modes of the visuality of allegory in selected works from Philippine art history that in their complex mediations materialize the people and dignity of their predicament and their prevailing. Philippine art can be divided as three different features: passion, vagrancy, and mass formation. The passion stage was depicted as deep structure of Christian thought and devotional feeling, harsh capitalist system. In the pictures of vagrancy, under the regime of Ferdinand Marcos, the themes of drift, deprivation, and homelessness are reckoned through the images of pictures. The stories represented with allegory have been played an important role to bring local issues up as national ones. Those stages take us to the processes of mass formation or the depiction of the people as a moment in the totality of force. The allegorical sign refers to another sign that precedes it, but with which it will never able to coincide reach back to a previous stage and in this constant attempt at return incorporates a structural distance from its origin. The true people's art is one that radically generates transformative technologies and techniques so that it irrevocably breaks the plane of "art". In the painting, the truth is represented by functioning as foundation of a rhetoric of the image. And at this axis, the passional, the vagrant, and the mass formation tend to come together because they render the form of contingency that must be suffered and hopefully surpassed, a Filipino subjectivity that must be stitched in time.

  • Recently, owing to the technology advances in computer science and image processing, age of face classification have become prevalent topics. It is difficult to estimate age of facial shape with statistical figures because facial shape of the person should change due to not only biological gene but also personal habits. In this paper, we proposed a robust age of face classification method by using Gabor feature and fuzzy support vector machine(SVM). Gabor wavelet function is used for extracting facial feature vector and in order to solve the intrinsic age ambiguity problem, a fuzzy support vector machine(FSVM) is introduced. By utilizing the FSVM age membership functions is defined. Some experiments have conducted to testify the proposed approach and experimental results showed that the proposed method can achieve better age of face classification precision.

  • In this paper, a motion adaptive deinterlacing algorithm is proposed. It consists of three parts: (1) modified edge-based line average, (2) pixel-based consequent five-field motion detection, and (3) block-based local characteristic for detecting true motion and calculating the motion intensity by using an improved method which is able to detect the inner part of moving objects precisely as well as to reduce the risk of false detection caused by intrinsic noises in the image. Depending on the detected motion activity level, it combines spatial and temporal methods with weighting factor. Simulations conducted on several video sequences indicate that the performance of the proposed method is superior to the conventional methods in terms of both subjective and objective video quality.

  • This study aims at considering and analyzing the stature of denim clothing as an ornament as well ai how aesthetic meaning and human being's mental side indwell in the development of denims. which will be proceeded in the future, from the view of contemporary culture of dressing. It is found that the stylishness expressed through denim clothing is formed on the basis of the cultures of party, drawing and disorganization, and the result of the study was as follows. Firstly, the culture of party became the source of for decoration of denim clothing, and denim clothing more glamorize women as a party-look which makes the most use of its advantage to be comfortable and able to display in various ways with splendid artificial jewelry, patchwork, dyed pattern which is elaborately embroidered. Secondly, Such culture of drawing is applied to denim clothing so that denims are expressed to make people feel more human being's warmth as being free from the existing stereotype and formality. Thirdly, the most outstanding feature of denim clothing showed in the culture of disorganization is to make the most use of vintage style as it is. This reflects an image of the culture of disorganization under postmodernism, which is free from the traditional conception of the existing dressing by destroying the original form, in the way of slashing, making a hole and tearing. That is, people can sufficiently express not only free sense of release based on postmodernism by wearing denim clothing, but also human being's intrinsic desire for restoration of humanism or human warmth with splendid decoration or various techniques such as handicraft. It can be recognized these features as the reasons, that make denim clothing place themselves as an original fashion item, by giving denim clothing technical decoration in recent years.

  • The purpose of this study is to examine the works of choreographer Philippe $Decoufl{\acute{e}}$ and the performance costumes designer Philippe Guillotel, and identify the intrinsic values shown in the formative characteristics in their works. And it proposes a vision and a direction for the development and performance of modern fashion phenomenon of media convergence performing arts complex. The results were as follows. First, the performance characteristics shown in Philippe $Decoufl{\acute{e}}$'s art pattern applies dynamic improvisation, decategorization reflected in the media interactivity, time and space of a variable scalability, complex artistic genres and transcends cultural boundaries. Second, the characteristics of the performance costume can be described as a co-existence between dynamics of aesthetic layers, 'Media body' represented by the interaction of the compounds with the technology, and integrated variable expandability. And aesthetic values inherent in the performance costumes are summarized as abstraction, playfulness, reproducibility, and theatricality. Modern fashion performance and limited production of the center 'costumes' in the fashion images can be used in diverse ways, and innovative marketing has gone through a change in image production. Metaphysical text of the advanced performance genre can be presented in a new perspective to fashion derivatives 'Media body'. And the aesthetics of popular culture kitsch, the grotesque, and surrealism in theater will produce creative stage direction.

  • Resting-state Functional Magnetic Resonance Imaging(fMRI) data detects the temporal correlations in Blood Oxygen Level Dependent(BOLD) signal and these temporal correlations are regarded to reflect intrinsic cortical connectivity, which is deactivated during attention demanding, non-self referential tasks, called Default Mode Network(DMN). The relationship between fMRI and anatomical connectivity has not been studied in detail, however, the preceded studies have tried to clarify this relationship using Diffusion Tensor Imaging(DTI) and fMRI. These studies use method that fMRI data assists DTI data or vice versa and it is used as guider to perform DTI tractography on the brain image. In this study, we hypothesized that functional connectivity in resting state would reflect anatomical connectivity of DMN and the combined images include information of fMRI and DTI showed visible connection between brain regions related in DMN. In the previous study, functional connectivity was determined by subjective region of interest method. However, in this study, functional connectivity was determined by objective and advanced method through Independent Component Analysis. There was a stronger connection between Posterior Congulate Cortex(PCC) and PHG(Parahippocampa Gyrus) than Anterior Cingulate Cortex(ACC) and PCC. This technique might be used in several clinical field and will be the basis for future studies related to aging and the brain diseases, which are needed to be translated not only functional connectivity, but structural connectivity.

  • We outline a process for estimating Cole-Cole parameters from time-domain induced polarization (IP) data. The IP transients are all inverted to 2D Cole-Cole earth models that include resistivity, chargeability, relaxation time, and the frequency exponent. Our inversion algorithm consists of two stages. We first convert the measured voltage decay curves into time series of current-on time apparent resistivity to circumvent the negative chargeability problem. As a first step, a 4D inversion recovers the resistivity model at each time channel that increases monotonically with time. The desired intrinsic Cole-Cole parameters are then recovered by inverting the resistivity time series of each inversion block. In the second step, the Cole-Cole parameters can be estimated readily by setting the initial model close to the true value through a grid search method. Finally, through inversion procedures applied to synthetic data sets, we demonstrate that our algorithm can image the Cole-Cole earth models effectively.

  • In this paper, we propose a rigid body tracking method in 3D space using 2D passive marker images from multiple motion capture cameras. First, a calibration process using a chess board is performed to obtain the internal variables of individual cameras, and in the second calibration process, the triangular structure with three markers is moved so that all cameras can observe it, and then the accumulated data for each frame is calculated. Correction and update of relative position information between cameras. After that, the three-dimensional coordinates of the three markers were restored through the process of converting the coordinate system of each camera into the 3D world coordinate system, the distance between each marker was calculated, and the difference with the actual distance was compared. As a result, an error within an average of 2mm was measured.
