Purpose: To compare the outcomes of bilateral lateral rectus recession between 20 and 25 prism diopters (PD) for intermittent exotropia. Methods: A retrospective study was performed with a total of 584 patients who underwent surgery for intermittent exotropia and were followed up for more than 12 months. The patients were classified into either the 20 PD group (5 mm bilateral rectus muscle recession [BLR]) or the 25 PD group (6 mm BLR). Successful postoperative motor alignment was defined as within 10 PD of exotropia and 4 PD of esotropia.Results: Cumulative probabilities of surgical success rates for 24 months were 77.9% in the 20 PD group and 54.8% in the 25 PD group, respectively (<EM>p</EM> < 0.001). Postoperative deviations in recurrence patients were 13.41 ± 3.64 PD and 14.66 ± 3.87 PD (<EM>p</EM> = 0.062) at postoperative 12 months.Conclusions: All patients with relatively small angle of exodeviation such as 20 PD had a higher success rate and small postoperative exodaviation at 12 months. Therefore, surgery could be considered when the eye is exodeviated with a relatively small angle. However, in the group with the exotropic drift, approximately 2/3 of the preoperative angle of deviation is measured with similar outcomes between preoperative and postoperative angles of deviation.

Purpose: The purpose of this study is to investigate the effect of unilateral medial rectus muscle resection (UMR) for the treatment of recurrent intermittent exotropia after bilateral lateral rectus muscle recession (BLR). Methods: Medical records of 121 subjects who underwent UMR for the treatment of recurrent intermittent exotropia after BLR with more than six months of follow-up were reviewed. Patients were classified into two groups, the 4-mm group who underwent 4-mm UMR and the 5-mm group who underwent 5-mm UMR. Successful postoperative motor alignment was defined as within 10 prism diopters (PD) of exotropia and four PD of esotropia. Results: The mean time interval between the primary surgery and recurrence was 13.55 ± 20.78 months (1-120 months). Average follow-up period after secondary surgery was 27.42 ± 15.98 months (6-48 months). Cumulative success rate at six months after UMR was 87.1% in the 4-mm group and 88.2% in the 5-mm group, respectively, and that at 24 months was 72.7% in the 4-mm group and 50.0% in the 5-mm group (<EM>p</EM> = 0.132). The average effect of resection was 4.87 ± 0.91 PD/mm in the 4-mm group and 4.73 ± 0.84 PD/mm in the 5-mm group (<EM>p </EM>= 0.374). Conclusions: Because of recurrent intermittent exotropia, less time is required for surgery in UMR after BLR, and patients and parents are more likely to accept a secondary surgery because of single muscle surgery. Therefore, UMR may be an effective surgical method for patients with 16-30 PD of recurrent intermittent exotropia.J Korean Ophthalmol Soc 2014;55(11):1681-1686

This research is a series of studies to find out the differences between onomatopoeia and mimetic word in Korean which examined each inherent phonological characteristic with comparing phonological differences composing onomatopoeia and mimetic word. Main results are as follows. First, more mimetic words are composed in Korean than onomatopoeia with 962 onomatopoeias and 3,441 mimetic words in typical Korean. Second, letters high frequently appearing in anlaut of onomatopoeia is in order of ‘vowel-ㄸ- ㄷ-ㄲ-ㅌ’ and mimetic word is in order of ‘vowel-ㅂ-ㅅ-ㄲ’. Third, ‘plosive’ appears more frequently in onomatopoeia than mimetic word in anlaut. Four, the most onomatopoeia ends with ‘ㄱ, ㅇ’ in auslaut final consonant. Mimetic word ends with ‘ㄴ, ㅅ, ㅇ’ relatively higher than onomatopoeia. Five, onomatopoeia shows large difference in general vocabulary than mimetic word phonologically.

<표준어 규정> 무용론에 대한 비판적 접근

This research is aimed to seek an alternative and criticize the argument of useless that 2000s appeared in earnest. The policy of standard language with Seoul as the center destroys using dialect and language variety. The standard language was criticized considerably because it was likely different from definition that “The language of moderm people are using the word widely”. An alternative to this, these are the way that make the best use of “the plural standard language” or we don`t need to use the regulation of standard language autonomously. These arguments are not irrelevant to appear a left leaning ideology that influenced by the 2000s social atmosphere or politics. Generally, the useless of standard language regulation emphasizes the role of “dictionary”. But these arguments are difficoult to realize considering the linguistic feature of Korea. Therefore the reaserch proposed to discriminate between the role and the illustration to the flexibility of standard language.

일반논문 : 흉내말의 어말 자음 교체에 대한 기능적 연구

박동근 ( Dong geun Park ) 한민족문화학회 2014 한민족문화연구 Vol.47 No.-

이 글은 한국어 흉내말의 어말 자음 교체 현상을 흉내말의 주요한 특징으로 인식하고 체계와 실태를 연구하는 것이 목적이다. 이를 위해 어말 자음 교체의 총 목록을 작성하고 대응 체계를 살펴보았다. 그 결과 ‘ㄱ ? ㄹ’, ‘ㄱ ? ㅁ, ’ㄱ ? ㅅ‘, ’ㄱ ? ㅇ‘, ’ㄴ ? ㄹ‘, ㄴ ? ㅁ, ㄴ ?ㅅ’, ‘ㄹ ? ㅅ’, ‘ㅁ : ㅅ’, ‘ㅁ : ㅇ’ 등 모두 10개의 자음 교체를 확인하였다. 어말 자음 교체가 갖는 뚜렷한 체계적인 특성은 보이지 않는다. 다만 같은 조음 위치들끼리 활발히 일어나는 경향이 있다. 어말에 오는 7개의 종성가운데 ‘ㅂ’은 유일하게 자음 교체를 하지 않는다. 국어사전의 뜻풀이를 확인해 보면, 각 자음에 대한 기존의 음성상징에 대한 해석과 실제 뜻풀이 사이에 상관성을 찾기 어렵다. 다만, 의성어에서 종성 ‘ㅇ’은 [울림]을, 의태어에서 종성의 ‘ㅅ‘은 [미완]의 자질을 갖는 것으로 해석할 만하다. 한편 국어사전의 뜻풀이는 어말 자음 교체 쌍에 대한 진지한 고려가 없었다. 특정한 어말 자음 교체형들은 그 중 한쪽의 사용 빈도가 높게 나타나는 경향이 있다. ‘ㄱ-ㅇ’에서는 ‘ㅇ’이, ‘ㄹ-ㅅ’에서는 ‘ㅅ’이 뚜렷한 사용 우위를 보인다. 이는 앞으로 어말 자음 교체의 기저형 설정이나 국어사전의 뜻풀이에 참고할 수 있을 것이다. This study recognizes a phenomenon of the alternation of the word-final consonant of a symbolic word in Korean language as its major characteristics and aims to look into its system and actual condition. For this purpose, it drew up a total list of the alternation of the word-final consonant and inquired into its system of correspondence. As a result, a total of 10 alternations of consonant, ‘ㄱ-ㄹ,’ ‘ㄱ-ㅁ,’ ‘ㄱ-ㅅ,’ ‘ㄱ-ㅇ,’ ‘ㄴ-ㄹ,’ ‘ㄴ-ㅁ,’ ‘ㄴ-ㅅ,’ ‘ㄹ-ㅅ,’ ‘ㅁ:ㅅ’ and ‘ㅁ:ㅇ.’ There is no clearly systematic characteristic of the alternation of the word-final consonant. However, it has a tendency to take place actively between consonants in the same place of articulation. Of seven word-final codas, only ‘ㅂ’ does not make consonant alternation. In the definition in a Korean dictionary, it is hard to find a correlation between the existing interpretation of sound symbolism for each consonant and its actual definition. However, in onomatopoeia, final consonant ‘ㅇ’ deserves interpretation that it has a feature of [an echo] while in mimetic words, final consonant ‘ㅅ,’ a feature of [incompletion]. In the definition in the Korean dictionary did not seriously considers the pairs of the alternation of the final-word consonant. Certain types of the alternation of the final-word consonant tend to show a higher frequency of one of the two. In ‘ㄱ-ㅇ,’ ‘ㅇ’ shows superiority of use; and in ‘ㄹ-ㅅ,’ ‘ㅅ’ shows clear superiority of use. This can be referred to in establishing the underlying forms of the final-word consonant alternation or defining it in the Korean dictionary.

This study aims to examine the condition and characteristics of mimetic words derived from verb among symbolic words. For this, the study gave up the definition that mimetic word is based on sound symbolism, and discussed what is the range of mimetic word. It is not appropriate to divide words into two as symbolic words and non-symbolic words. From this perspective, the study set up pseudo-symbolic word and quasi-symbolic word, There were total 623 mimetic words derived from verb, which occupies 18% of entire Korean symbolic words. As the result of classifying the symbolic words derived from verb in types, verbs that verbs that are the original form of mimetic word tend to have more developed negative vowel than positive vowel. And in the relationship between verb and mimetic word, the direction of derivation integrally occurred from verb to mimetic word.

This study, in favor of the current policy of standard language based on codified "Regulation of Standard Language", aims to review the topics related to definition, correction rules, correction method of standard language and to seek for, not only its future policy, but also for selection directions of new standard language. Recent arguments on standard language focus more on ideological issues (therefore, the alert has been on this biased vision in this study) deviating from the fundamental intent of the enactment of standard language, which stands for "unification of language use in view of smooth communication". In this study, special attention has been paid to the fact that the disjunction between standard language and real language represents an inherent problem of standard language, as in virtual language, and moreover, that standard language is not learned by itself, but taught through education. Constant efforts should be made to diminish the gap between standard language and real language, but at the same time, it is necessary to admit that this gap is hard to eliminate completely. For this reason, standard language should be corrected and complemented within this range of understanding.
