Recently mobile phone camera become generally spread, it is required to develop high resolution, multi-functional camera module for obtaining high image quality. To satisfy this demand, number of pixels has been increased and pixel size decreased in small mobile phone cameras. As a result, image quality is seriously dropped by blur phenomena. Especially when hand tremble is occurred, image quality is dropped by camera shake. Therefore, to obtain high quality image, it is necessary to compensate user's hand tremble. In this paper, we propose voice coil actuator for compensating hand tremble, which can apply optical image stabilization (OIS) system. Sensitivity analysis and size optimization are performed to obtain high driving force. Finally, it is confirmed that the optimized electromagnetic circuit can be applied in OIS system.

Objective : This study is to propose a new hypothesis about the interpretation of Jueyinbing in Shanghanlun by studying 2 Jueyinbing cases. Methods : We analyzed the original form of the chinese characters 'Jue(厥)', 'Jueyin(厥陰)' and 'Huoluan(?亂)' and tried to understand their contexts in Shanghanlun. At the same time, we analyzed 2 clinical cases diagnosed and treated as Jueyinbing according to newly hypothesized definition. Results : Both patients suffered from eye diseases which caused by concentrating on a sophisticated work by straining their hands, feet and chest during the night time. After the herbal intervention, their eye diseases are improved firstly. The National Eye Institute 25-item Visual Function Questionnaire (NEI-VFQ) score increased on both patients. Not only all the patients' chief complaints relieved but their other clinical problems such as limb pain, hand tremble also improved. Conclusions : These results highly insist that, at least in 15 characters provision of Shanghanlun, Jueyinbing had had the different usage from the conventional terminology, and it is assumed that Jueyinbing means the disease made by concentrating on a sophisticated work by straining hands, feet and chest during night time.

Poet, painter and publisher, Roland $Gigu{\grave{e}}re$ is one of Quebec's outstanding figures, inspired by both Surrealism and Quebec nationalism. He participated in contemporary artistic movement 'Phases' and influenced collective self-awareness and political ferment, 'Quiet Revolution'. In La Main au feu(1973), his poetry represent a landscape dominated by darkness in contrast with red color of fire from the volcanic crater. The world is immersed in darkness of despair which allude to the Great Darkness of Quebec society. Acts of violence assume many different forms: crows, black rain, dark flow, frenzy of knife blows. Both things and humans are in the state of absence or lack. Life falls into opacity of death. In the background of dark landscape, we discover Miror, a singular character. Similar to chain of mountains and to bare forest, he is a creature that shape the tragic inner world of poet. He is as like as seismograph that record the tremble of being. Finally, in order to fight the darkness of environment, the poet attempt to use the power of fire of volcanoes. The flow of magma become paintings of his dream and the flame of eruption, poetry of cry toward the sky. 'La main au feu' means the will to resist injustice and repression in the world. The tragic reality is replaced by a dream that become second reality out of reach of the force of hostile external circumstances.

Spasmodic dysphonia, essential tremor, and vocal tremor related with Parkinson's disease are different disorders showing fairly similar symptoms such as difficulty in the speech onset, and tremble in the voice. However, the cause and the resulting treatment of these diseases are different. Spasmodic dysphonia is a vocal disorder characterized by spasms of the laryngeal muscles during a speech, invoking broken, tense, forced, and strangled voice patterns. Such difficult-to-treat dysphonia disease is classified as central-origin-focal dystonia, of a yet unknown etiology. Its symptoms arise because of intermittent and involuntary muscle contractions during speech. Essential tremor, on the other hand, is characterized by a rhythmic laryngeal movement, resulting in alterations of rhythmic pitch and loudness during speech or even at rest. Severe cases of tremor may cause speech breaks like those of adductor spasmodic dysphonia. In the case of hyper-functional tension of vocal folds and accompanying tremors, it is necessary to distinguish these disorders from muscular dysfunction. A diversified assessment through the performance of specific speech tasks and a thorough understanding for the identification of the disorder is necessary for accurate diagnosis and effective treatment of patients with vocal tremors.

There are three types of noise generated inside the vehicle: BSR (Buzz, Squeak, Rattle). In this paper, we propose a classifier that automatically classifies automotive BSR noise by using features extracted from deep convolutional neural networks. In the preprocessing process, the features of above three noises are represented as noise-map using STFT (Short-time Fourier Transform) algorithm. In order to cope with the problem that the position of the actual noise is unknown in the part of the generated noise map, the noise map is divided using the sliding window method. In this paper, internal parameter of the deep convolutional neural networks is visualized using the t-SNE (t-Stochastic Neighbor Embedding) algorithm, and the misclassified data is analyzed in a qualitative way. In order to analyze the classified data, the similarity of the noise type was quantified by SSIM (Structural Similarity Index) value, and it was found that the retractor tremble sound is most similar to the normal travel sound. The classifier of the proposed method compared with other classifiers of machine learning method recorded the highest classification accuracy (99.15 %).

This paper proposes a real-time method using a 3-axis accelerometer to enhance blurred images taken from a camera loaded in mobile devices. Blurring phenomenon is a smoothing effect occurring in photo images. Algorithms to cope with blurring phenomenon is essential since small-size mobile devices tremble severely by even a tiny hand-shaking of a user. In this paper, accurate sensing characteristics of the 3-axis accelerometer is acquired by applying the sensor in pendulum motion and the blurring phenomenon is modeled as a uniform distribution and Gaussian distribution. Also, non-Gaussian distributed model is observed in the experiment of real blurring phenomenon and a particular deblurring function is designed by reversing the model. It has been demonstrated that the application of trembling information to the deblurring function adequately removes the blurring phenomenon.

Objective : There has been no known report on the pain shock after administering Korean bee-venom therapy. Three accounts of pain shock were observed at the Sangji university affiliated Oriental medicine clinic from July 2001 through September 2001. This thesis will inform clinical progression and cautions on administering Korean bee-venom therapy. Methods: We were able to witness different patterns of pain shock during the treatment of degenerative knee joint, progressive oral paralysis, and A.L.S. In order to reduce heat toxicity of the bee venom, needling points were first massaged with the ice for 10 minutes before injecting $0.1{\sim}0.2cc$ of the bee venom. Points of injection were ST36, LI11, LI4 and others. Pain shock occurred after injecting on inner xi-an, outer xi-an and LI4. The phenomena associated with pain shock was recorded in chronological order and local changes were examined. Results: Through examining 3 patients with the pain shock, we managed to observe clinical progression, duration, and time linked changes on specific regions. We also managed to determine sensitive needling points for the pain shock. Conclution: Following results were obtained from 3 patients with the pain shock caused by Korean bee-venom therapy from July 2001 to September 2001. 1. Either positive or negative responses were shown after the pain shock. For case 1, extreme pain was accompanied with muscular convulsion and tremble, ocular hyperemia, delirium, stiffening of extremities, and hyper ventilation which all suggest positive responses. For case 2 and 3, extreme pain was accompanied with facial sweating, asthenia of extremities, pallor face, dizziness, weak voice, and sleepiness which are the signs of negative responses. 2. The time required to recover to stable state took nearly an hour (including sleeping time) and there was no side effect. 3. Precautions required to prevent the pain shock includes full concentration from the practitioner, accurate point location, precise amount of injection, physiological condition and psychological stability of the patient 4. Coping with the pain shock should be similar with a needle shock, and since extreme pain is accompanied, sufficient psychological rest must be provided. 5. Pain shock occurs because the patient cannot tolerate stimulation on the needling point. Thus, symptoms were similar to the needle shock in addition to excruciating pain. Further investigation and research must be done to have better understanding of an immune response and the pain shock associated with Korean bee-venom therapy.

A neural prostheses can be designed to permit stimulation of specific sites in the nervous system to restore their functions, lost due to disease or trauma. This study focuses on the feasibility of optoelecronic stimulation into nervous system. Optoelectronic stimulation supplies, power and signal into the implanted optical detector inside the body by optics. It can be effective strategy especially on the retinal prosthesis, because it enables the non-invasive connection between the external source and internal detector through natural optical window 'eye'. Therefore, we designed an effective neural stimulating setup by optically based stimulation. Stimulating on the sciatic nerve of a rat with proper depth probe through optical stimulation needs higher ratio of current spreading through the neural surface, because of high impedance of neural interface. To increase the insertion current spreading into the neuron, we used a parallel low resistance compared to load resistance organic interface and calculated the optimized outer parallel resistance for maximum insertion current with the assumption of limited current by photodiode. Optimized outer parallel resistance was at a range of 500Ω-700Ω and a current was at a level between 580uA and 650uA. Stimulating current efficiency from initial photodiode induced current was between 47.5 and 59.7%. Various amplitude and frequency of the optical stimulation on the sciatic nerve showed the reliable visual tremble, and the action potential was also recorded near the stimulating area. These result demonstrate that optoelectronic stimulation with no bias can be applied to the retinal prosthesis and other neuroprosthetic area.
