Full textAbstract:
Single sign-on (SSO) is a session verification mechanism that allows a client to use a single password and name combination to be able to access multiple applications. The mechanism validates the client for all the applications and eliminates the need for authentication prompts when a user switches between applications within a session. SSO mechanisms can be classified as software versus hardware or customer-requirements oriented versus server-side arrangements. The five commonly used mechanisms of Single Sign-On currently are: Web Single Sign-On, Enterprise Single Sign-On, Kerberos (or Ticket/Token Authentication), Open ID, and Federation or Federated Identity. SSO has the main benefit of allowing a user to access many different systems without having to log on to each and every one of them separately. However, SSO introduces a security risk as once an attacker gains access to a single system, then the attacker has access to all of the systems. This thesis describes SSO technology, the Security Assertion Markup Language, and the advantages and risks involved in using SSO. It examines authentication mechanisms and their suitability for SSO integration. The main emphasis is a description of a mechanism that ameliorates some of the disadvantages of SSO by monitoring the user behavior with respect to a template. If a user performs actions that fit the defined template behavior, then the post authentication mechanism will not get activated. If, on the other hand, a user does something unforeseen, the mechanism will not perform authentication for this user, but rather trigger manual authentication. If this manual authentication succeeds, then the user will continue to interact with the system, otherwise user session will be ended. This behavior extension authentication mechanism is a method that eases the authentication process in which users are not expected to remember any username and password that can be forgotten easily or have a biometric attribute that can change over time. This method can be integrated to existing web application without a major risk and increase in cost.<br>Single sign-on (SSO) är en sessionkontrollmekanism som gör det möjligt för en kund att använda en ett enda par av lösenord och namn för att kunna få tillgång till flera olika program. Mekanismen validerar klienten för alla anrop och eliminerar behovet av ytterligare inloggningsdialoger när en användare växlar mellan program inom en session. SSO-mekanismer kan klassificeras enligt olika kriterier, såsom programvara kontra hårdvara eller kunder krav orienterade mot serversidan arrangemang. De fem vanligen använda mekanismerna för Single Sign-On är närvarande: Web Single Sign-On Enterprise Single Sign-On, Kerberos (eller Token autentisering), Open ID och Federation eller Federated Identity. SSO har den stora fördelen att en användare kan få tillgång till många olika system utan att behöva logga in på vart och ett av dem separat. Men SSO inför också en säkerhetsrisk i och med att tillgång till ett enda av systemen också automatiskt innebär tillgång till samtliga. Denna avhandling beskriver SSO-teknik, Security Assertion Markup Language, och fördelarna och riskerna med att använda SSO, samt undersöker autentiseringsmekanismer och deras lämplighet för SSO integration. Tyngdpunkten är en beskrivning av en mekanism som minskar några av nackdelarna med SSO genom att övervaka användarnas beteende med avseende på en mall. Om en användare utför åtgärder som passar det beteende som beskrivs av mallen, då den föreslagna mekanismen kommer att hantera autentiseringen automatiskt. Om, å andra sidan, en användare gör något oförutsett, kommer mekanismen inte att automatiskt utföra autentisering för den här användaren, utan utlöser manuellt autentisering. Om denna manuella autentiseringen lyckas, så kan användare fortsätta att fortsätta att interagera med systemet, annars kommer användarsessionen att avslutas. Denna beteendebaserade utvidgning av autentiseringsmekanismen är en lovande metod som minskar behovet av att komma ihåg många namn och lösenord, utan att lämna delsystem öppna till de säkerhetsproblem som uppstår i ren SSO, och utan att vara beroende av biometriska egenskaper som kan förändras över tiden. Denna metod kan integreras med befintliga webbaserade lösningar utan ökad risk och ökade kostnader.

Full textAbstract:
The emergence of a language is rarely directly observed in a natural environment. Similar to a phenomenon previously observed in Nicaragua, deaf Dominican children appear to have created a rudimentary form of manual communication in absence of comprehensible linguistic input. The evolution of this communication system over the course of five years (2007-2012) is documented as part of a cross-cultural and cross-generational study in which sign complexity is analyzed. The role of innate and environmental components of language creation and acquisition are discussed using data from hearing children and parents, including the parents of the deaf Dominican children cited above.
Results confirm that a new communication system is indeed slowly emerging in the Dominican Republic, and that this system shows signs of evolution in the period extending from 2007 to 2012. Signs produced by the deaf Dominican children meet the minimal requirements for a communicative symbol, show signs of mutual intelligibility, and differ from the signs of the other implemented Sign Languages in the Dominican Republic. Two cohorts of manual communicators appear to be present, and younger signers seem to have more advanced linguistic competencies in comparison to older signers within the community. The signs that are part of the observed Dominican manual communication system also appear to differ in complexity from those produced by hearing adults and children, supporting the presence of innate abilities for language creation. Specifically, the deaf Dominican children are generally found to have more diversified sign repertoires and to display faster signing rates over time, in comparison to hearing adults and children. Qualitative data and quantitative trends further support a more complex understanding by deaf children of the use of signs as an independent communication system from speech.
Analyses looking at the impact of input on language creation provides some support for the existence of infant-directed signing in a way similar to what is observed with infant-directed speech. The use of repetitions by hearing adults using infant-directed silent gestures could provide support for usage-based theories of language development. That being said, young hearing children with no prior exposure to Sign Language and with minimal relative linguistic experience were found to produce signs equivalent in complexity to those of hearing adults, therefore potentially providing further support for an innate understanding of complex linguistic rules. Deaf Dominican children were further found to surpass the input received by hearing adults over time. In all, this research is consistent with previous studies attesting for children’s natural ability for language creation and development.

Full textAbstract:
There is a need to identify a specific test to assess one's Simultaneous Communication skills (a combination of Sign Language with the use of spoken English). The Simultaneous Communication Evaluation and the Sign Communication Proficiency Interview were examined to compare and to determine the reliability and validity for the latter. The Illinois Course Evaluation Questionnaire was used as an independent variable.
Multitrait-multimethod methodology (Campbell and Fiske, 1959) was used to examine construct validity of the two methods of assessing the twenty-eight subjects' communication skills, as well as to show their reliability. The Illinois Course Evaluation Questionnaire was used as an observation tool to obtain dichotomized scores used to measure subjects' performance in the classroom as compared with the two methods of assessing the subjects' signing skills.
Based on the findings of this research, the following conclusions seem justified.
A. The Receptive portion of the Simultaneous Communication Evaluation generally showed a weak relationship to the other tests with the exception of the Sign Communication Proficiency Interview's retest, with which it showed only a moderate relationship. This indicates that the Receptive portion may not be a valid way of assessing Sign Language competency.
B. Since the Sign Communication Proficiency Interview's test-retest and the inter-rater reliability indicators are moderately high, with their levels of significance being lower than .05, this method of testing may be regarded as an at least moderately reliable means of assessing the faculty members' skills in the use of Simultaneous Communication.
C. The correlations for the Simultaneous Communication Evaluation and the Sign Communication Proficiency Interview's test and retest are .8058 and .5477 respectively. The Illinois Course Evaluation Questionnaire, in general, showed negative correlations with the first two tests with the probability of error being higher than the acceptable .05. One may conclude from this that there is no relationship between the ability to teach and the ability to use Simultaneous Communication.
It is anticipated that the outcome of this study will have an impact on various programs and agencies that provide educational and/or social services to the hearing impaired in the United States. At present there is no established, standardized method of evaluating professionals Sign Language skills and this study may well set a precedent in this area.<br>Ed. D.

Full textAbstract:
Expressing the point of view of a character and marking changes in point of view (POV) are key aspects of narrative discourse. The concept of POV has been discussed in the literature in various contexts, including deixis, logophoricity and subjectivity. A variety of linguistic and non-linguistic devices are used to indicate a particular POV, including nominal and pronominal reference, and facial expressions and intonation. Spoken languages can mark changes in POV using strategies such as direct and indirect discourse, the former coupled with optional paralinguistic cues such as intonation, whereas signed languages can mark changes in POV in a unique way using referential shift. Referential shift is a common device in sign language narrative discourse, where the signer 'becomes' a referent by taking on one or more attributes of that referent, such as facial expression and/or body position (Loew, 1984). Within a referential shift construction, verbs and pronouns which are marked for first person refer to the referent being portrayed rather than the signer. This study examines how point of view is marked in three fables, each told by native users of British Sign Language (BSL) and native speakers of English, and explores how the strategies used by signers and speakers can be explained by theories of conceptual spaces, such as that suggested by Liddell (2003a) for signed languages and Ehlich (1979, 1985) for spoken languages.

Boudloche, Lloyd JR. "A Comparison of Manual Signing and PECS Within a Functional Communication Training Context." Thesis, NSUWorks, 2016. https://nsuworks.nova.edu/fse_etd/105.
Full textAbstract:
This applied dissertation study was designed to inform and advance knowledge regarding research in the area of the effectiveness of functional communication training (FCT) in reducing challenging behaviors among individuals with autism spectrum disorder (ASD) who were nonverbal, by using a quantitative single subject approach. The researcher specifically focused on determining which modality, Picture Exchange Communication System (PECS) or manual sign language, would be the most effective as a replacement behavior to bring about a reduction in challenging behaviors. Previous researchers in the field of FCT did not address this area, thus leaving a gap in the research.
The participants for the study were three children with ASD between the ages of 4 and 6. Prior to the start of the study, multiple assessments were administered to assess the function of challenging behaviors, level of functioning, imitation skills, and preferences.
The intervention phases consisted of randomly alternating between a session of PECS and manual sign daily with each session consisting of 10 trials. Baseline data was collected to assess preexisting skill level to mand for items. The intervention trials continued until the participants reached mastery level in either modality. Results demonstrated that only PECS was effective for both the participants who completed the study, and for the participant who mastered both manual signing and PECS, PECS had a quicker acquisition rate. Implications from the findings suggest that FCT is an effective intervention in reducing challenging behaviors, and that PECS might be more effective for quick reductions of challenging behaviors. The study is a valuable addition to the current FCT research as it aligns with and extends findings from previous research.

<p>In statistical inference of the distribution-free straight-line regression problem, two common transformations, rank transformation and sign transformation, are used to construct the test statistics. When shall we need to use the transformations and which transformation is more efficient are two common questions met by researchers. In this thesis, we will discuss the comparison of the efficiencies of the statistics before and after the rank transformation or the sign transformation in both theoretical and practical ways. Simulation is also used to compare the efficiencies of the statistics under different distributions. Some recommendations about when to use transformations and which one to choose are put forward associated with the conclusion drawn from the research work we have done.</p>

<p>In South Africa, Deaf people communicate with one another and the broader community by means of South African Sign Language. The majority of Deaf people who have access to a mobile <br>phone (cell phone) use Short Message Service (SMS) to communicate and share information with hearing people, but seldom use it among themselves. It is assumed that video messaging <br>will be more accessible to Deaf people, since their <br>level of literacy may prevent them from making effective use of information that is disseminated via texting/SMS. The principal objective of the <br>esearch was to explore a cost-effective and efficient mass multimedia messaging system. The intention was to adapt a successful text-based mass notification system, developed by a <br>local nongovernmental organization (NGO), to accommodate efficient and affordable video mass messaging for Deaf people. The questions that underpin this research are: How should video- streaming mass-messaging methods be compared and evaluated to find the most suitable method to deliver an affordable and acceptable service to Deaf people? What transport vehicles <br> <br> <br>should be considered: Multimedia Message Service (MMS), the web, electronic mail, or a cell phone resident push/pullapplication? Which is the most cost effective? And, finally: How does the video quality of the various transport vehicles differ in terms of the clarity of the sign language as perceived by the Deaf? The soft-systems methodology and a mixed-methods methodology <br>were used to address the research questions. The soft-systems methodology was followed to manage the research process and the mixed-methods research methodology was followed to <br>collect data. Data was collected by means of experiments and semi-structured interviews. A prototype for mobile phone usage was developed and evaluated with Deaf members the NGO Deaf <br>Community of Cape Town. The technology and internet <br>usage of the Deaf participants provided background information. The Statistical Package for Social Science (SPSS) was used to analyse <br>the quantitative data, and content analysis was used to analyse the documents and interviews. All of the Deaf participants used their mobile phones for SMS and the majority (81.25%) used <br>English to type messages<br>however, all indicated that they would have preferred to use South Africa sign language on their mobile phones if it were available. And they were quite willing to pay between 75c and 80c per message for using such a video-messaging <br>service.Of the transport vehicles demonstrated, most Deaf people indic indicated that they preferred to use the SMS <br>prototype (with a web link to the video) rather than the MMS prototype with the video attached. They were, however, very concerned about the cost of using the system, as well as the quality of the sign language videos.</p>

Full textAbstract:
As the demand for wireless electronics is increasing, more and more gadgets are connected wirelessly and devices are being improved constantly. The need of the new research and development for advance electronics with high performances is the priority. The data transfer rates are improved for faster communication and better efficiency is to reduce the battery consumption in handheld devices.
This thesis presents three single-stage power amplifiers (PAs): class-AB, class-F and inverse class-F (class-F-1) at 28 GHz. The PAs have identical input networks: input matching, base DC feed, and base stabilizing networks. At the load side, there is a different load network for each PA. Class-AB PA load network has a single inductor with a parasitic capacitor to create a resonance at 28GHz. Class-F PA load network is composed of a parallel network (one LC tank in series with an inductor) and a series network (one 3f0-resonance LC tank in series with a capacitor) to create a multi-resonance load network. Class-F-1 load network is composed of a parallel network (two LC tank in series with an inductor) and a series network (one 2f0-resonance LC tank in series with a capacitor) to have a multi-resonance network. The main purpose of using multi-resonance load networks in class-F and class-F-1 is to shape the collector currents and voltages in order to achieve the highest efficiency possible.
The chosen bias point is VCE=2.3V and ICE~12mA. As the results, class-AB PA achieves the peak PAE of 44%, 15 dBm OP-1dB, >19 dBm Psat , and 10 dB Gp. Class-F PA achieves the peak PAE of 46%, 14.5 dBm OP-1dB, ~18 dBm Psat , and 10 dB Gp. Class-F-1 PA achieves the peak PAE of 45%, 15.1 dBm OP-1dB, >18 dBm Psat , and 10 dB Gp.. In order to compare the linearity performances among three PA classes, a two-tone signal and a modulated signal with different modulation schemes (QPSK, 16QAM, 64QAM, and 256QAM) are applied to the PAs to produce IM3, ACPR, and EVM. After the analysis and comparison on efficiency and linearity, class-F PA gives the highest efficiency but has the worst linearity while class-AB has the best linearity but has the worst efficiency among three. Class-F-1 PA results lies in the middle of two other classes in term of efficiency and linearity.<br>Master of Science

variance on raw and/or total scores indicated that hearing signers outperformed
non-signers significantly on the CTT, Part 2. Both Deaf and hearing signers
significantly outperformed non-signers on the CTT, Part 1. Differences between
hearing signers and non-signers approached significance on the experimental

Full textAbstract:
Health and feeding outcomes for preterm infants depend upon healthcare providers’ ability to recognize non-verbal signs of distress during bottle-feeding. Methods of training future providers’ to interpret feeding behavior in preterm infants are unclear. This study used a pre-test/post-test design to compare the effects of in- vivo simulation and video-simulation training on students’ knowledge of feeding abnormalities, clinical judgment, and documentation accuracy. Fifty-two graduate level speech-language pathology students were assigned to the in-vivo (N= 27) or video-simulation (N= 25) group. Results revealed that both methods proved beneficial for increasing knowledge and clinical judgment skills. Participants trained using video-simulation training documented a greater number of distress signs. The use of patient simulators to train graduate level speech-language pathology students to use correct clinical judgment for managing abnormal feeding behavior is efficacious.

Full textAbstract:
A semi-quantitative indirect immunofluorescence assay was developed which distinguishes two types of patients from whom yersiniae are recovered: those who produce a strong yersiniae specific coproantibody secretory IgA (SIgA) response and those who do not. This SIgA response appeared to be yersiniae specific as faecal supernatant controls from patients whose stools where shown to yield negative or positive cultures for Salmonella, Campylobacter, or Clostridia were SIgA negative.
Organisms isolated from patients with high SIgA titers had a higher incidence of virulence associated characteristics although SIgA response was not associated with most other commonly recognized assays of virulence. A strong association was shown to exist between SIgA titre and mouse virulence, the gold standard of bacterial virulence.
Clinical examination of patients culture positive with yersiniae documented a strong association between acute enteric illness and high SIgA titre. This association was not dependant on the cultured yersiniae species.
No single in vitro virulence associated assay was found to be a reliable predictor of animal virulence. The virulence of nine Y.frederiksenii and one Y.kristensenii, previously thought to be non-pathogenic in man, was also documented.<br>Science, Faculty of<br>Microbiology and Immunology, Department of<br>Graduate

Full textAbstract:
All wounds are contaminated with bacteria; the decision to perform a wound swab is based on the presence of clinical signs and symptoms of infection. In acute wounds these include: pain, erythema, localised oedema, heat and purulence. Patients with chronic wounds may display covert signs of infection such as: an increase in serous exudate, delayed healing, friable granulation tissue, pocketing at the wound base and malodour. A wound swab should only be performed when the wound has been clinical diagnosed as infected. The problem that arises for the clinician is which method of collecting the wound swab should be employed.The aim of this research was to compare two semi-quantitative wound-swabbing techniques (Levine versus Z technique) to establish which method was more effective in determining the presence of bacteria in cutaneous wounds. The Levine technique involves rotating the wound swab over a 1 cm[superscript]2 area of the wound with sufficient pressure to express fluid from within the wound tissue. The Z technique involves rotating the swab between the fingers as the swab is manipulated in a 10-point zigzag fashion across the wound without touching the wound edge or peri wound skin. There is a scarcity of evidence in the literature to support the use of one method over the other, hence the need to undertake the study.A prospective randomised study of two paired wound swabbing techniques (Levine versus Z technique) was conducted. Two semiquantitative wound swabs were collected no more than five minutes apart, on each patient. The order of wound swab technique was randomised. All wounds were cleansed with normal saline using an aseptic technique prior to specimen collection. Differences between the detected microbiological bioburden values were analysed with t-test for paired sample.There were 28 males and 22 females. Acute wounds represented 42% (n=21) of the study population and the remaining 58% (n=29) were chronic wounds. Clinical signs of infection were present in 42% of patients with acute wounds. All patients with chronic wounds had one or more overt clinical sign of infection. A statistical difference in the number of organisms was detected between the two swabbing techniques. The Levine method detected more organisms (t = 15.46, p = <0.001), than the Z technique. There was also a statistically significant difference in the number of organisms detected in acute and chronic wounds. In acute wounds the Levine technique detected more organisms (t = 9.55, p = <0.001). In chronic wounds the Levine technique detected more organisms (t = 12.04, p <0.001).The Levine method proved to be more sensitive in detecting organisms present in cutaneous wounds in both acute and chronic wounds. Based on the results of this study, the Levine technique is the recommended method for collecting a wound swab.

This US fund has a specific investment strategy: it invests in sin stocks. We compared this mutual fund to The Timothy Fund because they have similar characteristics such as – date of inception, total assets, home country and investment universe, expect the investment strategy. Indeed, The Vice Fund invests in sin stocks and The Timothy Fund does not. Two benchmarks are also used in the study: the S&P 500 Index as a domestic benchmark and the MSCI World Index as an international benchmark. This thesis is a case study using a deductive approach on a quantitative ground. The study is done on ten years long from 2003 to 2012. We divided the entire period into three different sub-periods depending of the S&P 500 Index trend. The first and the last sub-periods are bullish and the second one is bearish. In order to analyse both the financial performances and the risks of The Vice Fund we use several tools. We calculated returns and risk-adjusted ratios: the Treynor’s ratio, the Sharpe’s ratio and the Jensen’s ratio. Because these ratios are less accurate in bearish markets, we calculated the normalized Sharpe ratio by doing linear regressions and we also calculated the modified Sharpe ratio. In order to perform these calculations, we used DataStream as a database to obtain prices and dividends for the two mutual funds and the prices for the two benchmarks. We got also the one-month T-bill to have a risk-free rate. We found that The Vice Fund had a better average returns performance whatever the market conditions over the period studied. However the difference between weekly results with The Timothy Plan Fund and the benchmarks is not statistically significant. The risk- adjusted ratios confirmed the superiority of the risk-adjusted financial performance of the sin fund.

碩士<br>國立臺灣科技大學<br>高分子工程系<br>91<br>The current image retrieval of road sign can process the image both observing from un-oblique angle and obtaining while its sign is not being deformed, in which, under the reversed conditions, the previous method will cause a wrong judgment. So we propose two effective methods to deal with the preceding condition.
It is hard to restore a curved or oblique color image. In this paper, we will analyze, process, recognize features of color curved or oblique images ( 2D circle image which is curved and changes into 3D curved image), and pose a method of restoring, including mending the shape, matching the color, and filling in the gap. Next, we compare the features of shape and color with those from the database and get a good result, we have been discussing color road sign images so far, and we will hope the result usefully by our way. So we propose an effective method to cope with the image what the preceding condition, expecting to compare with the image in the database established in the past and finding out its resemblance by my method.

碩士<br>國立臺北科技大學<br>電資碩士班<br>102<br>With the enormous cost down for the information production manufacture and the rapid proliferation of the internet and the world-wide-web, a tremendous amount of digital data spreads on the network across the international exchange and stores on the remote cloud equipment. The text content is easy to analysis and retrieve by the keyword. How to get and search the information hidden inside the images? The image content maybe include many people, objects and things familiar to humans. These image content should also be detected, identified, described, storage and indexing. Content Based Image Retrieval (CBIR) is a computer vision science, it retrieve information according to images content themselves. The vision data includes some features such as color, shape and texture. In this dissertation, we propose an object detection and recognition method to retrieve image information using Speeded Up Robust Features (SURF) and CBIR. CBIR is a promising approach by automatically searching image collection based on visual features extracted from the image files themselves without manual descriptive annotation. To analysis and retrieve the image information automatically and recognize the object in the image scene. SURF is a robust algorithm to detect and describe the local features in images. It can assist to find the correspondences between two images. In this paper we present the study by the traffic signs as examples of the object target. Search and match the features extracted from the images content. To detect and identify the object in a test image of the scene by the proposed method.

Purpose of study The purpose of this study was to evaluate the effect of different protocols of pain treatment on post-operative pain, vital signs, comfortable sensation, and anxiety in patients who have undergone cardiac surgery.
Background According to a nationwide survey by the Ministry of Health and Welfare Department, heart disease is the second leading cause of death in our country since 2014. Among heart diseases, coronary occlusion caused by ischemic heart disease accounted for half of all heart disease-related deaths. Because the number of patients undergoing open-heart surgery is increasing every year, post-operative pain control has become very important. Although there are some domestic and international studies focused on postoperative pain control in the literature, there is no study on the comparison of the effects of different protocols of pain control on vital signs, pain, comfort, and anxiety in patients who have undergone cardiac surgery.
Method This study was designed as a case-control study. Eighty patients who had undergone cardiac surgery were assigned equally to the fentanyl group with continuous pain control medications or the morphine group with intermittent pain control medications. The Hospital Anxiety Depression Rating Scale (HADS) and vital signs were measured before cardiac surgery. The Critical-Care Pain Observation Tool scores were measured on the day of cardiac surgery, and the Brief Pain Inventory, HADS, and General Comfort Questionnaire scores were measured 2 days after surgery and before discharge from the hospital. The collected data were analyzed with SPSS20.
Result The fentanyl group with continuous treatment for pain relief was better than morphine group with intermittent pain treatment, in terms of the intensity of the highest pain on the scale (p<0.001), current pain (p=0.009), and the scale of pain relief (p=0.001); all of these parameters reached statistical significance. Regarding the time of weaning the ventilator (p=0.191), there was no significant difference between the two groups. Moreover, there were less dynamic changes in the post-operative blood pressure and heart rate in the fentanyl group, which received continuous pain control treatment.
Regarding the effect of post-operative pain on the quality of life, parameters including post-operative self-care ability (p=0.02), mood (p<0.001), walking ability (p=0.002), return to work (p=0.037), sleeping quality (p=0.008), and leisure activity (p=0.008) reached statistical significance.
These results indicate that fentanyl group is better than morphine group in controlling pain post-operatively. However, regarding post-operative anxiety, depression, and comfort, there was no statistical significance between the two groups.
Conclusion After cardiac surgery, the use of the continuous pain control medications was more effective than intermittent pain control medications. In addition, continuous pain control did not prolong the duration of intubation or cause fluctuation in the blood pressure. A shortened post-operation recovery time and improved quality of life were also noted in patients who received continuous pain control medications. On the basis of the evidence-based data, we intend to develop a clinical guideline for the pain relief of patients who have undergone cardiac surgery or other major operations.

Full textAbstract:
碩士<br>國立交通大學<br>科技管理所<br>90<br>The fifty-year advancement of semiconductor has resulted in the prosperous development of information technology. Also, the frequent evolution of semiconductor technology has easily made an change on current industry environment. During the recent ten years, the rapid development in wireless communication has made the swift achievement in Radio Frequency IC (RF IC). Besides, the GaAs semiconductor technology used for RF IC becomes a hot topic for semiconductor investment in recent years. Although GaAs has good performance of high frequency , it cannot be integrated with main stream Si-base semiconductor technology. This is the fatal disadvantage of GaAs for future tendency of SOC (System On a Chip) technology.
In 1998, IBM had announced the SiGe technology for high frequency IC, which has direct influence on RF IC market. This paper is intended to study the future development and influence of SiGe semiconductor technology on RF IC market by comparing device characters and technology trend between SiGe and GaAs. In addition, this study is expected to provide a reference for a new opportunity and potential threat to investors of GaAs semiconductor technology.

This study was to compare the effects of the two communication modes of augmentative and alternative communication system (AAC) on teaching behavioral language for children with Autism Spectrum Disorder (ASD). Two children diagnosed with ASD participated. Background data were gathered through interviews with teachers and parents of the participants to gain information on communication skills.
An alternating-treatment design with baseline of single subject research was used. Separate analysis of the quantitative and qualitative data revealed discrepant findings. The independent variable was the use of AACs to see students with autism in cooperation, a request of a desired item, and motor imitation within a day in the life of a classroom. An assessment is also considered as a major set of the independent variables. The dependent variables were divided into three categories: cooperation with adults, requests, and motor imitation.
Results showed that 1)both communication strategies could increase the number of the rate of acquisition, 2)when either of mode was given choice, the children showed preference; and 3) social validity data gathered through end of the study questionnaire revealed that both parents and teachers believed that both interventions were effective strategies in children’s communication.
For future teaching suggestions were also provided at the end of this study.

Full textAbstract:
碩士<br>南華大學<br>歐洲研究所<br>99<br>During the developing process of human history, “language” is the symbolized and delivering tool animated by human beings who express perceptions or feelings of local subjects and matters through individual communications.
Among all language forms, animal idioms are vivid, interesting, and significant ones. They include abundant human thoughts, contain cultural values, represent interdependences between human and animals, and carry essentially historical meanings which are renewed, combined, maintained, and lasted through human interactions and generation changes in the elapsing time and historic progress.
Thus, “Animal Idiom”, “Human Thought”, and “Culture” are inseparable while a great diversity of animal idioms is caused by multicultural backgrounds, distinctive folk activities, varied manners and customs, plentiful point of views, and distinct religious beliefs.
To absorb and comprehend the connotations from animal idioms, one of the objective ways is to collect different animal idioms, trace historically related records and documents, and make them into comparisons. Hence, with curiosities and a thirst for knowledge, the author intends to explore and analyze distinctions and similarities between English and Chinese animal idioms by representatively taking 12 Chinese signs as examples for briefly demonstrating three cultural core values defined by the author.
