Southeast Asian languages are famous for having a large number of vowel sounds with an average of more than 20 vowel sounds in this certain language family. In addition, there are approximately 1,500 languages in this area, which accounts for approximately 20% of total languages in the world. For this reason, vowel systems of Southeast Asian languages should be explored to determine the nature of vowel structures of human natural languages. In this study, we analyze vowel systems of three languages, Tagalog, Malay and Thai, that have only primary or normal vowels and thus are relatively simple structures based on descriptive and analytic universals. We would also like to confirm if the six criteria of the tentative evaluation model taken from several previous literature is appropriate in applying analysis of vowel system universals under the method of the Greenbergian Universals or statistic universals. What we have found from this research are (i) the three languages have high level of universals with some exceptional cases such as three-vowel system of Tagalog, and (ii) some of the six criteria, together with some cases of analytic universals, are not quite suitable for understanding language-specific universals that are different from other languages.

This study investigates acoustic characteristics of English and Korean voiceless sibilant fricatives as they appear before the three vowels, /i/, /$\alpha$/ and /u/. Three measurements - duration, center of gravity and major spectral peak - are employed to compare acoustic properties and vowel effect for each fricative sound. This study also investigates the question of whether Korean sibilant fricatives are acoustically similar to the English voiceless alveolar fricative /s/ or to the palato-alveolar /$\int$/. The results show that in the duration of frication noise, English /$\int$/ is the longest and Korean lax /s/ the shortest of the four sounds. It is also observed that English alveolar /s/ has the highest value, whereas Korean /s/ shows the lowest value in the frequency of center of gravity. In terms of major spectral peak, while English /s/ reveals the highest frequency, English /$\int$/ shows the lowest value. In addition, evidence indicates that there is a strong vowel effect in the fricative sounds of both languages, although the vowel effect patterns of the two languages are inconsistent. For instance, in the major spectral peak, both Korean lax /s/ and tense /$s^*$/ show significantly higher frequencies before the vowel /$\alpha$/ than before the other vowels, whereas both English /s/ and /$\int$/ exhibit significantly higher frequencies before the vowel /i/ than before the other vowels. These results indicate that Korean sibilant fricatives are acoustically distinct from both English /s/ and /$\int$/.

As the world develops into a global society, more and more people want to speak foreign languages fluently. To speak fluently, you must have sufficient training in speaking, which requires a dialogue partner. Recently, it is expected that the development of voice recognition information technology will enable the development of a system for conducting foreign language speaking training without human beings from the other party. In this study, a test bed system for foreign language speaking training was developed and applied to elementary school classes. Elementary school students were asked to present their English conversation situation and conduct speaking training. Then, satisfaction with the system and potential for continuous utilization were surveyed. The system developed in this study has been identified as helpful for the training of learning to speak a foreign language.

The purpose of this study was to clarify the origin which have misused terms, analyze Its meanings and suggest the unified terms. The content of this study are as follows. The origin of the terms in western dress is different with the areas of cultural influence. Japanese occupied much more than other languages in the apparel industry after the civilization. and English has dominated in the educational filed since 1945 the Liberalization. French, German, Portuguese, Spanish, Dutch are added. These languages came to the clothing field via Japanese and English or directly from the countries. 망토(manteau프), 메리야스(medias스), 러닝셔츠(일) 라사(raxa네), 오트 쿠튀르(Haute Couture 프), 비로드(veludo 포), etc. However the words of foreign origin have misused or corrupted until now a days. 마이 (재킷, 상의), 노 슬립, 소데나시 (슬리브리스, 민소매) 넌라쟈(브래지어), 노타이, 노타이샤쓰(오픈칼라 셔츠, 넥타이를 매지 않은 셔츠) 와이샤쓰(드레스 ttu츠), etc. And also these terms are confused in using because of the word's diversity, the different nationality, change of the marking rules, and the difference between the education and production field terms. On the others hand, this study explained the differences between western costume and Korean costume as the clothing manufacture terms were translated to Korean. bodice-길, collar, neckline-깃, belt, sash-(허리)띠 And then the untied terms were suggested through the comparison production field and educational area (including schools and institutes). lapel, 라펠(학교용어) (학원용어), 가에리 (일) (의류산업 현장용어), 아랫깃(통일어) By the way, this study involved the origin of and misused teams in sewing and presented the unified terms. 미까시 (X)-미 카에시(일) - 안단($\bigcirc$), 이새(X)―홈줄임 ($\bigcirc$) As the above , the characteristics of clothing terms which have misused are Japans,;e, corrupt Japanese, false reports foreign words via Korean, Japanese, compound words of Korean and Japanese, compound words of English and Japanese. And also the words of foreign origin in clothing had the following tendency in the marking system. There are ellipsis of form, sex, timber, grammatical case '-ing', '-ed' in adjective and long vowels express to short vowels. We can see this phenomena as the rule of curtailment labor.

It is practiced by many Korean medical institutions to give weights to medical papers published n foreign journals covered by major international abstracts and indexes (A&I) in the evaluation of research performance. In an attempt to recommend the databases to be used for the evaluation of KOrean medical research papers, this study measured the extent of overlap records of Korean medical papaers retrieved from the three major medical databases, EMBASE, MEDLINE and SCISEARCH. Korean papers published in foreign journals between 1990 to 1995 were analyzed. It also analyzed the characteristics of journals where these Korean medical papers are published with respect to their subjects, publishing countries and languages. It is found that these is no difference among three databsases as far as the characteristics of journals where Korean medical papers are published are concerned with respect to their subjects, publishing countries and languages. Thus the number of papers retrieved from each database should be the major criterion to recommend the A&I databases to be used in the evalua ion of research performance. If one database must be chosen for the evaluation of Korean medical papers, it is probably the best to utilize SCISEARCH which is the most efficient database for verifying Korean medical papers in foreign journals. If two databases can be used, then EMBASE should be the next choice.

Modern challenges in the educational environment force scientists and practitioners to search for an adequate answer. In particular, the war in Ukraine demonstrated the importance of developing information competence as one of the main means of distinguishing true information from a whole stream of fake news. This is especially relevant in connection with the introduction of distance learning when students must find and process a large amount of information on their own. Therefore, the purpose of the article is to analyze the training of higher education students through the prism of acquiring the necessary level of informational competence in war conditions. For this, general scientific and special research methods, as well as the experimental method, were used. In the results, the peculiarities of the interpretation of information competence in the distance form of education among modern researchers are determined, the psychological components of resistance to fakes are analyzed. Based on the conducted empirical measurements, it was established that thorough work on student education gives positive skills when working independently with Internet materials, strengthens the ability to distinguish false information and propaganda from the real state of affairs. The conclusions summarize the results of the empirical research and suggest ways to improve the situation with the formation of information competence.

Voice onset time (VOT) is known to be a primary acoustic cue that differentiates voiced from voiceless stops in the world's languages. While much attention has been given to the sound change of Korean stops, little attention has been given to that of English stops. This study examines VOT of stop consonants as produced by English speakers in comparison to Korean speakers to see whether there is any VOT change for English stops and how the effects of stop, place, gender, and individual on VOT differ cross-linguistically. A total of 24 native speakers (11 Americans and 13 Koreans) participated in this experiment. The results showed that, for Korean, the VOT merger of lax and aspirated stops was replicated, and, for English, voiced stops became initially devoiced and voiceless stops became heavily aspirated. English voiceless stops became longer in VOT than Korean counterparts. The results suggest that, similar to Korean stops, English stops may also undergo a sound change. Since it is the first study to be revealed, more convincing evidence is necessary.

Objectives: The purpose of this study was to compare the liberal arts curricula of domestic 3 year and 4 year dental hygiene departments and to obtain the basic data for the development of a standardized dental hygiene curriculum. Methods: The liberal arts curricula of fifteen 3 year and 4 year dental hygiene departments in Korea and other countries were analyzed. A survey was conducted on 801 selected dental hygiene majors from December 8 to 12, 2014. A self-reported questionnaire was completed by 750 dental hygiene students and 150 dental hygiene professors. The questionnaire consisted of 5 questions of general characteristics and 13 questions including curricula change, usability of curricula, awareness of the suitability of dental hygiene curricula, and validity of curricula. Cronbach'a alpha was 0.71 in this study. Results: The grade point average in the liberal arts courses in Korean 4 year dental hygiene departments were 29, which was higher than that in 3 year dental hygiene departments of 13.2. There were large disparities among the colleges in the credits of these courses. The most common liberal arts courses in 4 year dental hygiene departments were foreign languages, man, society and communication, and natural science. In 3 year dental hygiene departments, English and foreign languages were the most common courses, followed by computer, man and society, philosophy and ethics. Foreign languages were considered to be the liberal arts course that should be most strengthened according to the job environment change of dental hygienist in globalizing society, followed by social psychology and pedagogy. Conclusions: Liberal arts courses were offered in the 4 year dental hygiene departments than in the 3 year dental hygiene departments in Korea, but there were a great deal of differences between colleges. The preparation of standardized guidelines on liberal arts courses are necessary. Liberal arts courses should support the performance skill and knowledge of the dental hygienists.
