This study was conducted to identify the characteristics of pauses and breath groups made by normal adults and patients with voice disorders while reading a paragraph. Forty normal female adults and forty female patients with a functional voice disorder (18-45 yrs.) read the "Gaeul" paragraph with the "Running Speech" protocol of the Phonatory Aerodynamic System (PAS), by which the pauses with or without inspiration and between or within syntactic words and breath groups were analyzed. The number of pauses with inspiration was found to be higher in the patient group, but the number of pauses without inspiration was higher in the normal group. The rate of syntactic word boundaries with pauses with inspiration was higher in the patient group, while the number of syllables per breath group was higher in the normal group. As these results can be explained by patients' poor breath support due to glottal insufficiency, the question of whether voice disorder patients use their pauses and breath groups properly should be considered carefully in evaluation and intervention.

Images of medical treatment on PACS environment are digitized and they make saving and transmission of patient's information easy with CD format causing increase of patients transfer rate between hospital and data transmission as well. Figuring out the configuration of confining status of copied images of medical treatment with CD format and present the appropriate way of identification for personal information. 20 general hospital over 500 beds which are utilizing PACS currently. Questionnaire investigation focusing on PACS operation center and it's management people. In accordance with the law of securing personal information of public organizations, it says "Anyone who wants to see his or her information via representative he or she needs to make a letter of attorney and turn in this to the president of it's possessing facility" in the article 16. Based on the investigation of general hospital for CD copy issue status near metropolitan area, 8 out of 20, were issuing CD copy through personal identification process(the person oneself and representative) and 10 general hospital were doing by getting signature of receiptor only without identification of the person oneself and 2 general hospital confirmation process is not at all. By the law of securing personal information of public organization, article 16, confirmation process is supposed to mandate lawfully with a letter of attorney when there is any request of reading and/or copies of one's information. But in reality, there were no consistent rules on reading, the process and coverage of copy issue, rejection coverage of copy issue of CD copy in each general hospital PACS operation center. Therefore there is a big need for consolidated format which is applicable by law when the representative requests to issue of CD copy that is storing medical treatment images. By issue through this consolidated format, securing medical information of individual and systemic operation and management will be valid and effective.

Melody intonation therepy (MIT) is to improve the linguistic aspects of the verbal utterance for aphasic patients utilizing the intact right brain. It is applied to the aphasic patients with good comprehension, poor fluency, and little available speech are thought to be ideal candidates. The purpose of the study was to investigate the effects of Korean Melody intonation therapy (kMIT) in patients with non-fluent aphasia. Five male non-fluent aphasic patients were participated in this study. Average ages were 49.9 years old. Each therapy took 45-50minutes once a week for six months. Aphasic Screen lest (RISS) was used to assess language parameter such as Auditory comprehension, oral expression, reading, writing and calculation ability before and after kMIT. Mean of Length Utterance, verbal intelligibility and articulation disorder were assessed also. Computerized Speech Lab was used to assess the acoustic characteristics of aphasic patients before and after kMIT. The results are as follows : 1) Auditory comprehension, oral expression, reading, writing and calculation ability of the subjects increased after UH'. However, only oral expression showed significant difference (p<0.05). 2) Mean of Length Utterance of five patients generally increased after Un. 3) After kMIT, verbal intelligibility increased and showed significant difference (p<0.05). 4) Misarticulation rate generally decreased after m. 5) Voice Onset Time of the alveolar lenis /t/ and velar lenis /k/ gradually decreased after kMIT. 6) However, intonation pattern were increased gradually in yes'no question after kMIT.

Purpose : In a PACS(Picture Archiving Communications System) environment, which is a very important component in a digital medical environment, the compression of digital medical images is a necessary and effective feature. In a current system where JPEG is applied to the compression of medical images, this study is to examine effectiveness and suitability when the JPEG2000, a more advanced compression algorithm for still images, is applied to the compression of medical images. In this thesis, we attempt to address the compressibility for effective clinical usage when compressing medical images, applying the objectivization of clinical evaluation as a function of compressibility. In the experiment al method, the compression was applied at a fixed rate using JPEG2000, and the n the result was compared with compressed images by JPEG. Method : For the performance evaluation, we choose SNR(Signal to Noise Ratio) measurement of an objective evaluation of definition and analyze a subjective evaluation by the ROC(Receiver Operating Characteristic) method. The results of the experiment showed that in the case of JPEG2000 there is hardly any distortion of images, even at high compression ratio(100:1), while regarding noise, the SNR remains around about 40dB, which is also relatively high. Before reading by reference to evaluative materials concerning objective compressed images, it is impossible to apply high compression to images : however, after reading, this can be applied to images that have already existed for some time.

This study, by case investigation of book review, one of user-participation services in university library, and questionnaire investigation on librarians, aims at suggesting current statuses, problems, and improvement. This study investigated the services performed at 35 4-year universities establishing the department of library and information science. This study, except 7 ones which doesn't offer the service, investigated the service offered by 28 universities, classifying with 3 contents. As a result, the publicity and method in university library including event had an influence on use. This study was performed to increase participation rate and to promote reading activity. This study judged that book review is indispensible to university libraries. Libraries presented the opinions that, for the purpose of promoting active book review, libraries have to perform positive publicity, attractive event, support in the level of schools, librarians' wills, expansion of discussion cultures, offer of unified book review among universities, and linkage method with other organization reading program.

Charlotte $Bront{\ddot{e}}^{\prime}s$ novel Jane Eyre has long been doted on as one of the canonized texts of British literature since its publication. Seemingly, this romantic novel has nothing to do with plantation based on slave trade. However, paying a keen attention to the fact that Jane's enormous inheritance results from wine plantation at a colony, this essay re-interprets Bertha's drinking and madness as evidence of imperialism. For the porter/jin Bertha and Grace Poole enjoy might have some suspicious connection with wine, the very root of Jane's great expectations. Jean Ryes' Wide Sargasso Sea, writing Jane Eyre back, records Bertha as "a white resident of the West Indies, a colonizer of European descent" (326). However, Jane Eyre, in my interpretation, describes Bertha pretty much as a black Creole. At any rate, the view that the white West Indians are tainted by miscegenation proves contemporary racism and is reflected in the text through Bertha and her mother's intemperate drinking and madness. Drinking and madness are stigmatized as the evidence of the so-called "bad blood"; embodying the stereotypes of drinking, madness, and sexual corruption, Creoles, the very inescapable product of imperialism, provide a convenient excuse for justifying imperialism for purity, civilization, and moral cleanness. In this way, Jane Eyre needs to be re-interpreted politically and historically in the context of colonialism. British imperialism pursues a tremendous amount of profits through grape plantation and wine trades; however, it cleverly leaves in the colony the associated images such as intemperate drinking and madness. Bertha, transferred from Jamaica to Britain, takes in these negative images of "savageness." Transcending the narrow confines of feminist criticism obsessed with doubling between Bertha and Jane, this essay, accordingly, reads Bertha the prisoner in the attic as the captive for perpetuating imperialism. This reading hinges upon interpreting Rochester and St John as colonizers bearing the so-called "white men's burden" to cultivate and civilize savages much like crops such as grapes and sugarcane in the colonial plantation.

This study examines the effect of luminance contrast ratio of character on readability and visual fatigue during an hour-long reading session while using a tablet PC in ambient environments having low luminance limited to $25cd/m^2$. Experiments were conducted with four patterns of the tablet's luminance contrast ratio of characters, namely 1:2.5, 1:4.5, 1:6.5, and 1:8.5, in low ambient luminance of $9cd/m^2$ and $25cd/m^2$. The obtained results show that the characters can be easily read at the luminance contrast ratio of character of 1:8.5 under surface luminance of $25cd/m^2$. Visual fatigue was evaluated through a subjective survey of symptoms. Physical, psychological, and visual fatigue were observed at a surface luminance of $9cd/m^2$, whereas solely visual fatigue was felt at a surface luminance of $25cd/m^2$. By assessing the physical fatigue using the value, it has been found that smaller the luminance contrast ratio of character, greater is the CFF variation rate. Furthermore, readability is poor and visual fatigue can be observed when the surface luminance is lower than the ambient luminance. However, readability can be improved by increasing the luminance contrast ratio of character to a value of 1:8.5. Thus, in low luminance environments, luminance contrast ratio of characters can affect readability and fatigue. Consider providing the full form of "CFF" so that the acronym can be used unambiguously throughout the manuscript.

In the recent power industry, a change is taking place from manual meter reading to remote meter reading using AMI(Advanced Metering Infrastructure). If such the power data generated from the AMI is recorded on the blockchain, integrity is guaranteed by preventing forgery and tampering. As data sharing becomes transparent, new business can be created. However, Ethereum blockchain is not suitable for processing large amounts of transactions due to the limitation of processing speed. As a solution to overcome such the limitation, various On/Off-Chain methods are being investigated. In this paper, we propose a interface server using data sharding as a solution for storing large amounts of power data in Etherium blockchain environments. Experimental results show that our power-data processing system with sharding method lessen the data omission rate to 0% that occurs when the transactions are transmitted to Ethereum and enhance the processing speed approximately 9 times.

The installation rate of AMI(: Advanced Metering Infrastructure) capable of automatic electricity measurement is less than 43% nationwide and 10.5% in rural areas, which is very poor. Therefore, for the smart grid, automatic information recording of the watt-hour meter is required. For this purpose, it is necessary to develop a system capable of remote meter reading and use control by improving the existing watt-hour meter. In this paper, in order to enable the AMI function of the existing electricity meter, the remote meter reading and control technology of the existing electricity meter for AMI, the core of the smart grid, was developed using IoT and AI. The main research content was to recognize numbers using Tensorflow and Open-cv to convert it into a power meter sensing device for SG. We confirmed and checked the performance using the protyope system.
