Background: This study aimed to investigate the effect of elastic band-resistive exercise using audio-visual medium on pain, proprioception, and motor function in adults with chronic neck and shoulder pain. Design: One group pretest-posttest follow-up experimental design. Method: Twenty adult women with neck and shoulder pain voluntarily participated in this study. Elastic band-resistive exercise using audio-visual medium including cervical flexion and extension, shoulder external rotation, and scapular retraction-protraction motions was conducted 5 times a week for 3 weeks. The Numerical Rating Scale, pressure threshold tool, CROM goniometer, and Image J software were used to assess subjective pain level, tenderness threshold (pain), joint position sense error (proprioception), joint range of motion, and postural alignment (motor function), respectively. Result:: The pain intensity and threshold and joint position sense error showed significant decreases after the intervention, whereas the joint range of motion angle revealed significant increases. The postural alignment including forward head posture and rounded shoulder revealed significant improvements after the intervention. Conclusions: Therefore, we suggest that elastic band-resistive exercise through audio-visual medium would be helpful in preventing and managing pain and physical dysfunction in individuals with chronic neck and shoulder pain, and then it would support the development of health management-related online education content.

Typography in visual communication design is 'potential form' hidden within a space. Showing rhythm in typography is making 'aesthetic sense' in a graphic which has formative characteristics, the way of expression is very important. When the rhythm is recognized through visual stream, Rhythmic Sense is formed. The research will present a new form of the Visual Rhythmic Sense by analyzing typography works out positively. First of all, I researched works done by Fillippo Marinetti, Robert Massin, Wolfgang Weingart, and David Carson for their vigorous experimentalism in typography in forming visual rhythm. I used S.D. Scale method to analyze characteristics of visual image and VARIMAX for factor analysis reaching types of visual rhythm, which could be classified as following. (1) Synesthesia Rhythmic Sense (R-synesthesia) means that the senses are conveyed through 'visualization of auditory sense' and 'visualization of touch' (2) Simultaneous Rhythmic Sense (R-simultaneity) means that the time and space co-exist in one plane. (3) Connective Rhythmic Sense(R-connection) means that different factors (Within one plane) co-exist interacting with one another and creating a unified impression through such a process. (4) Artist Oriented Rhythmic Sense ($-artist) means that the artist interprets the content subjectively and expresses his/her impression, thereby, attracting a gaze of audience systematically and arbitrarily. (5) Reader Oriented Rhythmic Sense(R-reader) avoids the existing legibility formed through aggressive engagement of the reader.

The descending control system is composed of a group of structures in the midbrain, medulla oblongata and pons that form a network of descending inhibitory projections. In the clinical setting, it has been shown that the application of a electrical counterirritant to these structures and diminishes the pain in patients. Thus, depression and anxiety have been shown to predict the development of chronic neuropathic pain state. These factors could influence pain might also involve descending controls. Interestingly, reduced descending controls are seen in patients with irritable bowel syndrome and theses patients had greater anxiety, depression compared to controls. And, the influence of anxiety on the chronicity of pain and on the descending control pathways should be tested in animal models, using modern techniques. Given this Knowledge, it is no wonder that pain is a highly personal experience that is susceptible to a variety of biologic, pharmacologic, and environmental influences.

Stomatognathic system is a complex one that is composed of TMJ, neuromuscular system, teeth and connective tissue, and all its components are doing their parts to maintain their physiological relationships. Mandible, in particular, performs various functions such as mastication, speech, and deglutition, the muscular activities that determine such functions are signalled by numerous types of proprioceptors that exist in periodontal membrane, TMJ, and muscles to be controlled by complicated pathways and mechanics of peripheral and central nervous system. Orthodontic treatment, especially when accompanied by orthognathic surgery, brings dramatic changes of stornatognat is system such as intraoral proprioceptors and muscle activities and thus, changes in patterns of mandibular function result The author tried to analyze changes in patterns of mandibular movement and physiologic activities of surrounding muscles in Skeletal Class III ortlrognathic surgery patients who presently show a great increase in numbers. The purpose of this study was to draw some objective guidelines in evaluating funclierual aspects of orthognathic surgery patients. Mandibular functional analysis using Biopak was performed for skeletal Class III prognathic patients who underwent IVRO(lntraoral Vertical Ramus Osteotmy), and the following results were obtained: 1. Resting EMG was greater in pre-surgical group than the control group, and it showed gradual decrease after the surgery. Clenching EMG of masseter and anterior temporalis of pre-surgical group was smaller than those of control group, they also increased post-surgically, and significant difference was found between pre-surgical and post-surgical(6 months) groups. 2. Resting EMG of anterior ternporalis was greater than that of all the other muscles, but there was no significant difference. Clenching EMG of anterior temporalis and masseter were greater than those of the other muscles with statistical difference. In swallowing, digastric muscle showed the highest EMG with statistical significance. 3. Limited range of mandibular movement was shown in pre-surgical group. Significant increase in maximum mouth opening was observed six months post-surgically, and significant increase in protrusive movement was observed three months post-surgically.

Transient receptor potential ankyrin 1 (TRPA1), responding to noxious cold (${\leq}17^{\circ}C$) and pungent compounds, is implicated in nociception, but little is known about the coexpression of TRPA1 and other channels or receptors involved in the nociception in craniofacial regions. To address this issue, we characterized the TRPA1-immunopositive (+) neurons in the rat trigeminal ganglion (TG) and investigated their colocalization with other proteins known to be expressed in nociceptive neurons, such as transient receptor potential vanilloid (TRPV1) and $P2X_3$ receptor, using light microscopic immunofluorescence labeling method with TRPA1 and TRPV1 or $P2X_3$ antisera. The majority of TRPA1+ neurons costained for TRPV1 (TRPV1+/TRPA1+; 58.8%, 328/558) and 41.2% only expressed TRPA1 but not TRPV1. The TRPV1+/TRPA1+ neurons were small and medium sized. In addition, we investigated the colocalization of TRPA1 with $P2X_3$, a nonselective cation channel activated by ATP that may be released in the extracellular space as a result of tissue damage and inflammation. Among all TRPA1+ TG neurons, 26.1% (310/1186) costained for $P2X_3$, whereas 73.9% (876/1186) of TRPA1+ neurons did not coexpress $P2X_3$. $P2X_3$+/TRPA1+ neurons were predominantly small and medium sized. These results suggest that TRPA1+ neurons coexpressing TRPV1 or $P2X_3$ are involved in specific roles in the transmission and processing of orofacial nociceptive information by noxious cold, heat, and inflammation.

As Digital technology developed, drawing animation, using traditional production method which expresses many feelings with drawn lines loses the youth group, the primary audience, to the realism of the digital cinema. Drawing animation, which drew attention of the youth by the spectacles in the film such as hectic pace, dynamics and punch, declined for a while. However, it has been developed a way to express pace and dynamics of its own by establishing an effective directing method, which combines digital technology as it is needed. This study has a purpose to investigate what causes the dynamics and feeling of fast movement of the character in Japanese limited animation. Though some action-animated films that heroes with supernatural powers take the leading role that feeling of velocity and dynamics are emphasized we compare the directing method before and after the introduction of the digital technology. This research reaches the conclusion by factoring each Bergson and McLuhan's discussion to the intervention of indexical signs and the audience's participation according to skipping technique. This study has a significance of researching the element of drawing animation that maximizes the expansion of the senses by defying the limitation of the law of physics through its unique way of directing together with growth of the hero films, which will continue.

The purpose of this study is to investigate the meaning and process of scientific observation. Hence, this study reviewed and discussed meanings and process of scientific observation described in philosophy, the philosophy of science and science education. Major researches on scientific observation are focused on a characteristic and type of scientific observation behavior. These research can suggest what is the characteristic of observation facts generated by observer. But it cannot show what is the meaning and process of scientific observation, it should be provide to students. According to the result in this study, scientific observation is affected by observer's subjective factors, such as experience, background knowledge, interpretation(not inference) and observation skill. All factor are integrated as an intellectual framework, and it is able to be changed by the observed facts. On the other hand, inference is excluded on scientific observation, but it have constantly affect on intellectual framework through feedback. This study on scientific observation provides a scaffold in various activities of scientific observation to be provided to students.

The purpose of this study was to investigate secondary science teachers' brain activation and functional connectivity during scientific observation on the biological phenomena. Twenty six right-handed healthy science teachers volunteered to be in the present study. To investigate science teachers' brain activities during the tasks, 3.0T fMRI system with block design was used to measure BOLD signals in their brains. The SPM2 software package was applied to analyze the acquired initial image data from the fMRI system. The results have shown that the left inferior frontal gyrus, the bilateral superior parietal lobule, the left inferior parietal lobule, the left precuneus, the left superior occipital gyrus, the right middle occipital gyrus, the right precuneus, the left inferior occipital gyrus and bilateral fusiform gyrus were significantly activated during participants' scientific observation. The network model consisted of eleven nodes (ROIs) and its ten connections. These results suggested the notion that scientific observation needs a connective cooperation among several brain regions associated with observing over just a sensory receiving process.

Fashion is subjected to newness and change by itself. Fashion trend and tendency which could predict next season akeady indicated that digital and cybel11ation environment lliould be factors in fashion. Changes in future life styles and values caused by digital environment must be variables as fashion objects by themselves. Therefore digital environment of a fashion itself and that all encountered in fashion will not only be an existing situation but also an objective and a factor which must be pursued with fashionable sense in future fashion. Advanced technology and social change in relation to digital environment requires that educational method as well as its content will be changed on the scene of education for future. Thus we should seek an educational direction in fashion design for future society in which digital environment requires new paradigm. Subject to these backgrounds this study has an intension to study the change in fashion extensively influenced by expanded digital environment on a limited situational level of fashion design education and to suggest an educational direction for professional in future fashion design who will serve as a core of fashion area in the future. It is essential that education of professional in fashion for future should be achieved by digital-minded level that eagerly understands and accepts future society in which digital environment will be a main axis. It is necessary for this to make them expetience computers, digital media including CAD program. We have to note that education of digital media is more effective and applicable when accomplished in CAI level which can be related and expetienced with fashion education rather than mere functional training in media themselves. Intellectual creativity will be a vety source of producing values and national competence in 21st centtury. Education of design professional in fashion area must positively accept these environmental charactetistics in future society, as well as deeply reflect the education for the future.
