Male sexual differentiation involves a cascade of events initiated by the presence on the Y chromosome of the of the SRY (sex determining region of Y chromosome) gene, which causes the indifferent gonad to develop into a testis. Hormonal products of the testis, predominantly testosterone and Mullerian inhibiting subtance (MIS), then control the sexual differentiation of the developing fetus. SRY is a transcription factor; however, target genes for its action have yet to be identified, because the DNA recognition sequence for SRY is found in many genes. Therefore the study of intersex disorders is being used to identify other genes active in the pathway of sexual differentiation. Patients with 46,XY gonadal dysgenesis, or Swyer's syndrome, have streak gonads, normal stature, and a sexually infantile phenotype with Mullerian structures present. The inheritance is usually sporadic but can be autosomal dominant or X-linked recessive. Unlike 45,X patients, stigmata of Turner syndrome are rare. As many as 20 to 30% of patients are at risk for malignant gonadal tumor formation and should undergo gonadectomy soon after the diagnosis is made. We have experienced a case of Swyer syndrome which showed a positive SRY gene in peripheral blood and gonad. So we report this case with a brief review of literatures.

Purpose: This study was conducted to identify the differences by the stages of change in exercise behaviors of caregivers based on Transtheoretical Model. Methods: The subjects were consisted of randomly chosen 105 caregivers working in a nursing home. The collected data were analyzed with descriptive statistics, chi-square test, ANOVA and Duncan test using IBM SPSS Statistics 19. Results: The results showed that in the stages of exercise behaviors, there were most participants in contemplation stage with 24.7%, followed by 22.8% in preparation, 21.9% maintenance, 19.0% action and 11.4% pre-contemplation. As for the process of change by the stages of change in exercise behaviors, it showed statistically significant differences in behavioral strategies (F=7.64, p<.001). In decisional balance, pros (F=3.75, p=.007) showed statistical significance, with higher pros in all stages except pre-contemplation. Self-efficacy was also statistically significant (F=6.25, p<.001), especially in the maintenance stage. Conclusion: This study suggested that in order to encourage caregivers to exercise, a strategic intervention to reinforce the process of change, recognition of positive decision-making and promotion of self-efficacy in exercise behaviors should be developed.

This study focused on analysis of experience for adults' reunion with original family members who had lived in child care facilities during the childhood and adolescence. It was researched based on the grounded theory from nineteen participants have interacted with their own separated family members for more than ten years after had been reunited with them. As written in the result section of the study using the paradigm model analysis showed that it was caused by feel regret by reunion, absence of belonging and repeated abandoned wound. The contextual condition appeared as sensitive memories as wounded and frustration of compensation mentality. The centralization phenomenon came in a whirlpool of emotion. The intervention condition appeared as recognition of filial piety, support system for parents and healing their parents mind. The action-interaction showed up as revenge with good will, setting own boding free, inspire of own pride, family reconciliation. The consequence appeared as family sublimation, successful execution of life task and getting living foundation. This research made practical and political proposals based on above result and described the limitations of the study and the proposals for the latter study.

With the recent development of deep learning technology, remarkable achievements have been made in many research areas of computer vision. Deep learning has also made dramatic improvement in two-dimensional or three-dimensional human pose estimation based on a single image, and many researchers have been expanding the scope of this problem. The human pose estimation is one of the most important research fields because there are various applications, especially it is a key factor in understanding the behavior, state, and intention of people in image or video analysis. Based on this background, this paper surveys research trends in estimating human poses based on a single image. Because there are various research results for robust and accurate human pose estimation, this paper introduces them in two separated subsections: 2D human pose estimation and 3D human pose estimation. Moreover, this paper summarizes famous data sets used in this field and introduces various studies which utilize human poses to solve their own problem.

Performing industries in Korea and abroad have been attempting a wide range of artistic experiments utilizing online platforms ever since the Covid-19 pandemic. Accordingly, this study will shed light on the functional characteristics of Zoom, which was used as a creative tool for theater performances. At first, after examining theater performances presented in Korea and abroad using Zoom and their characteristics, the production stage of the Zoom play will be analyzed by dividing it into following stages; a research-based pre-production stage, a scene workshop stage that composes each scene based on the script, a recording stage filming each scene on Zoom, and Streaming stage for presenting the show. Furthermore, the actor's approaches to acting in this production process was presumed to be separation of gaze, re-recognition of space, utilization of expressive gestures, and reaction as an active action. As a result, it proposes the possibility of ongoing development of theatrical work using Zoom and the evolutionary aspect of actor's acting approaches in accordance with theatrical work via Zoom.

This essay interprets envy not as a form of conventional conflict between women but as a type of common response of self-preservation focused on envy represented in the American film, Single White Female, and the Korean film, Female Teacher. Although envy is traditionally classified as a feminine emotion, it is an innate human emotion regardless of gender identity. Especially in the competitive era of neo-liberalism, we recognize only its negative side while overlooking its positive side as envy originates from comparison with others. Hedy's mimicking of Allie in Single White Female is not the same as idealized identification because her envy is aggressive and a self-assertive response while transforming Allie's identity. Likewise, envy of a protagonist in Female Teacher triggers an action of self-preservation against irrational social and personal inequality. Accordingly, a type of resistant and critical power resides in envy between women in these films. Therefore, proper recognition of repressed envy is required in order to prevent its transition towards a violent outcome.

Medical services should be provided not only to patients but also to medical staff who are the main actors of medical treatment. This paper is based on Ethnography, observing the behavior of medical staff performing medical actions and finding what is the most frequent of physical medical treatment. In particular, I observed the need for recognition and performance of the clinical workforce for invasive medical treatment. Based on the Insight from the observation and analysis of medical staff's behavior on intravenous fluid therapy and in-depth interview, I defined four design value factors. Plus, I suggest a design prototype with a proposal for designing a medical consumable kit for intravenous fluid therapy to validate the design elements. Kitting medical consumables simplify the preparation and disposal process throughout the treatment, enabling rapid medical action and increasing work efficiency.

Unlike the conventional dramas, most of characters of tvN drama speak dialectic from Chonnam province. I could predict that watching this drama would influence the feelings, cognitions and behaviors of youth from that province. By interviewing 7 participants, I found that they felt strong familiarity with little exceptions. They recognized the being of dialectic and discovered the attractiveness of dialectic, and the necessity of preservation also. After watching the drama participants made a resolution to speak dialectic more, and made active actions to meet contents and people about dialectic. In conclusion, dialectic could be developed as an important element for interesting contents. The drama has a power to influence youths to change the feelings, recognitions, and actions. So I assert that the use of dialectic in the drama should be considered discretely and positively.

In this paper, we propose a deep learning-based person re-identification method using a three-dimensional RGB-Depth Xtion2 camera considering joint coordinates and dynamic features(velocity, acceleration). The main idea of the proposed identification methodology is to easily extract gait data such as joint coordinates, dynamic features with an RGB-D camera and automatically identify gait patterns through a self-designed one-dimensional convolutional neural network classifier(1D-ConvNet). The accuracy was measured based on the F1 Score, and the influence was measured by comparing the accuracy with the classifier model (JC) that did not consider dynamic characteristics. As a result, our proposed classifier model in the case of considering the dynamic characteristics(JCSpeed) showed about 8% higher F1-Score than JC.

To deploy Gate Recurrent Units (GRU) on resource-constrained embedded devices, this paper presents a reconfigurable FPGA-based GRU accelerator that enables structured compression. Firstly, a dense GRU model is significantly reduced in size by hybrid quantization and structured top-k pruning. Secondly, the energy consumption on external memory access is greatly reduced by the proposed reuse computing pattern. Finally, the accelerator can handle a structured sparse model that benefits from the algorithm-hardware co-design workflows. Moreover, inference tasks can be flexibly performed using all functional dimensions, sequence length, and number of layers. Implemented on the Intel DE1-SoC FPGA, the proposed accelerator achieves 45.01 GOPs in a structured sparse GRU network without batching. Compared to the implementation of CPU and GPU, low-cost FPGA accelerator achieves 57 and 30x improvements in latency, 300 and 23.44x improvements in energy efficiency, respectively. Thus, the proposed accelerator is utilized as an early study of real-time embedded applications, demonstrating the potential for further development in the future.
