PRONUNCIATION CHALLENGES OF MANDARIN PHONEMES ZH, CH, SH, D, AND T AMONG SMPIT CHENG HOO MAKASSAR STUDENTS
Full text linkThe differences in the phonological systems between Indonesian and Mandarin often cause difficulties for learners, especially in the consonant sounds zh, ch, sh, d, and t which do not have direct equivalents in Indonesian. These pronunciation difficulties, especially in junior high school students, are not free from errors in pronouncing the consonants h, ch, sh, d, and t, so this study shows and describes the form of pronunciation difficulties of the consonants zh, ch, sh, d, and t directly in grade IX students of SMP IT Cheng Hoo Makassar, and identifies the factors causing these difficulties. The research method used in this study is descriptive qualitative with 15 students as subjects. Data were collected through pronunciation tests, syllable tests, observations, structured interviews, and audio recordings. The results showed that most students had difficulty pronouncing the retroflex consonants zh and ch, as well as the aspirated consonant t. Errors that emerged included difficulties in tongue articulation, failure to distinguish between aspirated and non-aspirated sounds, and interference from Indonesian, for example, zh is pronounced as j and t is pronounced as d. Physiological factors such as a stiff tongue position also affect pronunciation accuracy. In conclusion, ninth-grade students of SMP IT Cheng Hoo Makassar still face significant challenges in pronouncing certain consonants in Mandarin. These findings emphasize the need for more targeted phonetic teaching strategies, such as explicit articulation exercises and the use of audio-visual media, so that students can improve their accuracy and confidence in speaking Mandarin
Novel electrochromic aromatic poly(amine-amide-imide)s with pendent triphenylamine structures
No full text[[abstract]]Three new aromatic poly(amine-amide-imide)s (PAAIs) having pendent triphenylamine units were prepared from the phosphorylation polyamidation reactions of a newly synthesized diamine, N,N-bis(4-aminophenyl)-N',N'-diphenyl-1,4-phenylenediamine, with three imide ring-preformed dicarboxylic acids. These PAAIs had inherent viscosities of 0.54-0.86 dL/g, and they were amorphous and readily soluble in many organic solvents and could be solution cast into transparent, tough, and flexible films with good mechanical properties. They displayed relatively high glass-transition temperatures (279-287 degrees C) and good thermal stability, with 10% weight-loss temperatures in excess of 522 C in nitrogen and char yields at 800 degrees C in nitrogen higher than 67%. The solutions of polymers in NMP exhibited strong UV-vis absorption bands with a maximum around 315 nm. The hole-transporting and electrochromic properties were examined by electrochemical and spectroelectrochemical methods. Cyclic voltammograms of the PAAIs prepared by casting polymer solution onto an indium-tin oxide (ITO)coated glass substrate exhibited two reversible oxidation redox couples at 0.67 and 1.08 V vs. Ag/AgCl in acetonitrile solution. All the PAAIs revealed very stable electrochromic characteristics, changing color from original pale brownish to green, and then to blue at 0.67 and 1.08 V, respectively. (c) 2005 Elsevier Ltd.
