國際學生滿意度和服務期望研究:以靜宜大學為例

為了解決Implementation scien的問題，作者孫紹綾 這樣論述：

This study aimed to explore international students’ satisfaction with campus services. The research focused on international students who have studied at Providence University for at least 6 months. This study investigated how academic services, campus environment, administrative services, and inte

rnational students’ social engagement would influence their perspectives on the services offered by Providence University. Qualitative research was applied to this study to explore international students’ insights. Additionally, to fulfill the purposes of the research, a semi-structured interview wa

s conducted. Twenty international students were recruited in the interview to indicate their satisfaction they perceived toward campus services.Results in this study were analyzed by content analysis. The findings reveal that international students are highly satisfied with campus environment at Pro

vidence University. It also reveals international students’ contentment toward administrative services and their ability to adapt to campus. Although results show much dissatisfaction with academic services, students still hold positive perspectives with the overall campus services. The findings of

this research may not only benefit Providence University by indicating services that should be addressed or enhanced, but also assist to further develop an outstanding international image.

基於音頻訊號隱藏技術之聲波數位傳輸

為了解決Implementation scien的問題，作者林煒利 這樣論述：

Information hiding was born in the early 20th century which was an emerging cross-discipline in many technical fields, such as signal processing, information security, communication, and human auditory system theory. It is mainly divided into two major branches: digital watermarking and steganograp

hy. Different from the general traditional encrypted information security method, the information hidden type realizes secure communication transmission by hiding the existence of secret messages. As the time when large amounts of information are widely available to many people, largely through comp

uter technology, information hiding acts as one of the means to protect intellectual property rights, secret communications has been increasingly studied and ap-plied in many fields.This paper proposes a method of audio hiding by hiding information in the frequency domain via short-time Fourier Tran

sform (SFTF). The carrier audio was using MATLAB applied STFT convert into the frequency domain. In the frequency terms which were inaudible, the signal is modulated according to the embedded secret message, and then generated by inverse short-time Fourier Transform (ISFTF) converted into secret aud

io. After the secret audio is broadcasted by the playback device, it is recorded by the radio device and then short-time Fourier transform can be used to reversely analyze the hidden secret message.The subsequent papers applied to the SFTF’s window function coefficients of the audio hiding system an

d verified that the secret message embedding amount of the system was up to 17.24bit/s. Experiments have also confirmed that the system can interpret secret messages normally at a forward radio distance of 90cm, and has excellent robustness when the signal-noise ratio (SNR) is higher than 5dB. In th

e end, this audio message hiding system is integrated into a graphical user interface (GUI) application with MATLAB's App Designer function.
