As society gradually enters a virtual, non-face-to-face society, the use of online content is increasing as well. In particular, as smartphones are thoroughly established in our daily life, the platforms of webtoons, mobile broadcasting, and education are shifting from personal computers to smartphones. Recently, the development of the Over-The-Top media service (OTT service) enabled streaming services of various media contents through the internet and activation of IPTV. Therefore, the rapid increase of popularity of short-form content is a natural phenomenon with smartphone platforms with fast, improvised, and endless communication. Lately, TikTok became the favored platform with prosumers, defined as people who are both producers and consumers. In this study, I studied the experiential response of YouTube and TikTok users as representative examples of a short-form content platform developed after the 2000s, the flourishing years of digital content with a length of 30 seconds.

What is an exhibition? Is it of the system which is designed to serve Art Works in their representation, or is it a place where the artistic presentation could be considered as art work itself? After modernist era, the role of exhibitional space might have been shifted from those two principle raison d'$\^{e}$tre of exhibitional space into another, a new one. What Deleuze would call it as he borrowed the term from Spinozian philosophy : the Affectional Space. This new type of exhibitional space has been announced since 1969 when a Harald Szeeman, young independent curator and art critic from Swiss, has organized his brilliant exhibition "When Attitudes become Form" in Bern. For sure, these intensities in curatorial practices have been existing before like some early 20th century exhibitional efforts by Marcel Duchamp, El Lissitzky, Yve Klein, etc. It has influenced much on many of, otherwise most of contemporary art exhibiting practices. And now it seems to be necessary to give it a conceptual idea which could enlighten better the new paradigm of exhibitional practices that we try to clarify. I would propose the idea of that new exhibitional space as "space of non-organic becoming". This idea is inspired by Deleuze's ever famous philosophical work Thousand Plateaus, which, with Folds by the same author, has contributed to many contemporary and aesthetical debating issues. What is "affect"? Explaining about Spinoza's principle concepts, Deleuze defines it as a kind of durations or variations which are constituted by different levels of perfection. One perfection is precedented or followed by certain perfection bigger or lesser through lived transitions or passages. So each time it actualizes and reflects the state of All as a cut of Reality while each state of affections, images or ideas can not be separated from the duration which binds it to the precedent state and extends it to following one. Affect is also a term of changes. One affects at the same time it is affected. Exhibitional space as affect (or affectional space) is distinguished from representational and presentational space in the way it attributes movement, produces arrangements and generates new factors of artistic creation including those which are outside of ever accepted artistic elements. The concepts of affectional space are used especially to enlighten contemporary situation of artistic and curatorial processes. Art is no more limited to be seen as mere objects of aesthetical admiration, nor as art vis-$\`{a}$-vis art relationship apart from the whole. It includes possibilities and virtuality that appear in the imperceptible and undescribable manners if delimited in given language. As once noticed by Kuhn, we might be living in a paradigmatically shifting world, not only in Art but also in Life. And we need to express it more with Art as moving and affectional nods than as just a clean window or a distinct manual book.

Condylar process of mandible is an important and fuctionally versatile part of the mandible. There were quite large amount of investigations on the functional and anatomical adaptation of the temporomandibular joint(TMJ) to the surrounding tissues. But controversies on the mechanism of functional adaptation of the joint still exist. In this research, we investigated changes in the TMJ by the lateral deviation of the maxillary incisor to shift the mandible right, and bone the undecalcified microscopic sections with fluorescent microscope and von Kossa staining with bright field microscope. Results were as follows: 1. Lateral deviation rendered shifting and tilting of the mandible, There were, compressions in the right joint and opening of the left joint space at early stage. At the same time, both condyles shifted slightly to anterior. 2. After $2{\sim}4$ weeks, left condyle showed anterior displacement and compressions in the joint space. Right condyle showed only slight shift to the anterior. 3. Regardless of the direction of the lateral shift, anterior bite plate compressed both condyle heads until 2 weeks. 4. There are bone resorptions in the anterior aspect of the condyle head and apposition of posterior border. Bone remodeling were observed between 3 and 4 weeks. 5. After 8 weeks of the experiment, there were little differences in condylar morphology between experimental and control group, though slight shifting and compression were still present in the experimental group. Lateral deviation of mandible evoked active remodeling of the TMJ until functional and anatomical reconstruction of TMJ position was achieved.

With the increased quality of life, the meaning of houses is shifting from a functional space for the simple purpose of residing to a symbolic space representing life as personality. Starting with the advancement of IKEA into Korea last year, global brands are about to enter into Korea. As Korean brands are not certain about how to set their direction in the situation where global brands have rushed into the market, it was thought that a key to solve the problem could be found from the cases of the lifestyle stores of Japan, which is moving one step ahead of Korea. Considering the circumstances, the author limited the subjects of this study to the lifestyle stores that have already established their brand identity and have prominent expressional characteristics of interior design in Japan. Research and analysis were conducted through site inspection and books. As a study method, literature and previous research were reviewed to find the program characteristics of interactivity and participation, the spatial characteristics of accessibility and the expressional characteristics of symbolism, scene continuity and function complexity, as the basis for an analysis. The results of the analysis showed that Japanese lifestyle stores are appealing to consumers as the spaces with their own differentiated space composition and various programs, by establishing their unique concepts and explicit brand identity. It is expected that such expressional characteristics of interior design will be of help in defining the direction of interior design of Korean lifestyle stores in the future.

Today, a definition of tourism is shifting from simple sightseeing to experiencing various cultures directly and/or indirectly. Along with the shift, all countries of the world dedicate their full attention on globalization project. In order to do so, they try to promote their images and cultures through eating and drinking spaces for food where the rest of the world can approach with ease. China is a country of diverse culinary culture. By analyzing eating and drinking spaces operated in four Chinese cities, this research studies how the traditional Chinese elements are expressed in modernization. With the research, it will navigate a direction as a new design way to establish modernized traditionality in the future. The research conducted an advanced research that set up and analyzed a standard frame of realizing practice for traditionality. By doing so, it sorted out and reviewed the characteristics of interior space into four styles; an indicative imitation method, a partial invoked method, a partial transformation method and a conceptual reception method. According to the outcome of an analysis, (a) the indicative imitation method that directly employed Chinese tradition was most used one, followed by (b) the partial invoked method that carried a part of traditional space, (c) the partial transformation method that simplified or transformed the tradition, and (d) the conceptual reception method that interpreted hidden minds and concepts by illustrating modern spirit over an inherent order in traditional Chinese space, in respective order.

As the need for low-cost, high-efficiency cubesats develops in the new space age, commercial paradigms are shifting in the private sector. This paper examines the challenges of launching and operating both domestic and foreign cubesats, and proposes practical solutions to ensure the robustness and reliability of the satellites from a practical perspective. In particular, the paper deals with checkpoints that are easy to miss, focusing on key events that can occur from the satellite deployment process through normal mode to mission mode in the operation scenario. Although the contents presented in this paper may not be technically applicable to all cubesat systems due to the different nature of each satellite bus system, they will be of some help during satellite assembly, integration and testing.

To obtain phase currents information in AC drives, shunt sensing technology is known to show great performance in cost-effectiveness and therefore it is widely used in low cost applications. However, shunt sensing methods are unable to acquire phase currents in certain operation conditions. This paper deals with the derivation of the boundary conditions for phase current reconstruction in three-shunt sensing inverters and proposes a voltage injection method to expand the measurable areas. As the boundary conditions are deeply dependent on the switching patterns, they are typically analyzed on the voltage vector plane for space vector pulse width modulation (SVPWM) and discontinuous pulse width modulation (DPWM). In the proposed method, the voltage injection and its compensation are conducted within one sampling period. This guarantees fast current reconstruction and the injected voltage is decided so as to minimize the current ripple. In addition to the voltage injection method, a sampling point shifting method is also introduced to improve the boundary conditions. Simulation and experimental results are presented to verify the boundary condition derivation and the effectiveness of the proposed voltage injection method.

PURPOSE: The Unilateral neglect is characterized by difficulty shifting attention to the side of space opposite the brain lesion and frequently reducing use of contralesional extremities. This study was to identify whether the visual deprivation was responsible for head position on unilateral neglect patient after stroke. METHODS: A patient with left middle cerebral artery infarction participated in the study. We assessed neglect using line bisection and star cancellation test. Patient was instructed to maintain correct alignment of trunk and head in a sit position. We evaluated degree of head lateral tilting and rotation. Then, patient was blocked visual input. Also, we evaluated head position in the same way. RESULTS: He scored 3 points in the line bisection test and 9 points star cancellation test. In postural evaluation, he had deviated posture such as lateral head tilting and rotation. After visual cue deprivation, patient showed different head position which was decreased degree of head tilting and rotation. CONCLUSION: For vertical body orientation, it was used multiple sensory references including the vestibular, somatosensory, and visual system. This finding suggested that abnormal posture of neglect patient could be related to the visual input. It has important clinical implications in terms of understanding the neglect.

Multilayer LTCC technology enables RF modules to be reduced dramatically by taking advantage of the three dimension flexibility. Compared to a conventional two dimensional PCB, LTCC allows higher density, reduced size, and lower cost. In this research, BPF based on LTCC for 900MHz ZigBee application was implemented which can replace SAW filter with using the material of the Dupont9599's dielectric constant 7.8. And distributed baud pass filter for 900MHz ZigBee system applications is presented. Using resonator stripline and capacitance, 2nd order band pass filter was designed. Adjusting resonator's length and capacitance is easy to tune at accurate center frequency by shifting band because ZigBee system is using narrow bandwidth, $902MHz^{\sim}928MHz$. Also resonator has no limitation in space, so reducing size is possibile. Designed filter had I.L. 2.8dB at 915MHz and attenuation at 815MHz, 1015MHz was 16dB, 15dB, respectively. Therefore, the sharpe cut-off and good insertion loss for ZigBee system application.
