        한글 두 글자 단어와 비단어의 어휘판단에 글자 빈도, 글자 유형, 받침이 미치는 영향: KLP 자료의 분석

        신명석,박창호 한국인지과학회 2023 인지과학 Vol.34 No.4

        본 연구는 한국어 심성어휘 데이터베이스(KLP-DB)의 분석을 통해 글자 빈도, 글자의 모음 유형, 받침 유무 등 글자 수준 정보가 두 글자로 된 단어와 비단어의 어휘판단에 어떤 영향을 주는지를 알아보고자 하였다. 반응시간과 오반응률에 대한 위계적 회귀분석을 실시한 결과 단어의 어휘판단에는 단어빈도가 중대한 영향을 미치지만, 첫째 글자의 빈도, 첫째 글자와 둘째 글자의 모음 유형과 받침 유무와 같은 글자 속성이 영향을 미쳤고, 두 글자의 모음 유형의 조합 및 둘째 글자의 빈도와 받침 유무의 조합도 영향을 주었다. 비단어의 어휘판단에는 첫째 글자와 둘째 글자의 빈도, 첫째 글자의 모음 유형, 첫째 글자와 둘째 글자의 받침 유무와 같은 글자 속성이 영향을 미쳤고, 두 글자의 사용빈도의 조합, 모음 유형의 조합, 및 첫째 글자의 빈도와 받침의 조합도 영향을 주었다. 단어빈도는 단어의 어휘판단에서 강력한 영향을 미쳤으며, 글자 속성은 단어보다 비단어의 판단에서 더 일관적인 영향을 미쳤다. 본 연구의 결과는 어휘판단과제에서 단어와 비단어 목록의 구성 및 반응시간의 해석에 글자 속성의 문제를 충분히 고려해야 함을 가리킨다. 글자 속성의 효과에 대한 이해는 단어 재인 과정의 이해에도 기여할 것이다. This study attempted to find out how lexical decision of two-syllable words or pseudo-words is affected by syllabic information, such as syllable frequency, syllable (i.e. vowel) type, and presence of final consonant (i.e. batchim), through the analysis of the Korean Lexicon Project Database (KLP-DB). Hierarchical regression of RT data showed that lexical decision of words was influenced by the frequency of the first syllable, the syllable type of the first and second syllables, batchim for the first and second syllables, and also by the interaction of the two syllable types and the interaction of syllable frequency and batchim of the second syllable. For pseudo-words lexical decision was influenced by the frequency of the first and second syllables, syllable type of the first syllable, and batchim for the first and second syllables, and also by the interaction of the two syllable frequencies, the interaction of the two syllable types, and the interaction of syllable frequency and batchim of the first syllable. Word frequency had a strong effect on lexical decision of words, while syllabic information had a stable effect on the lexical decision of pseudo-words. These results indicate that syllabic information should be seriously considered in constructing word and pseudo-word lists and interpreting lexical decision time. Understanding the effect of syllabic information will also contribute to the understanding of word recognition process.

        개방형 외비접근법을 통한 비중격 천공의 하비갑개 골막하 점막과 이개연골의 샌드위치 이식술

        신명석,최우영,양정열,김규보 대한미용성형외과학회 2012 Archives of Aesthetic Plastic Surgery Vol.18 No.2

        Repair of nasal septal perforation is a challenging problem to surgeons. Many surgical techniques which were reported through many literatures did not show high success rate constantly. The aim of this study was to examine the surgical technique of sandwich graft using inferior turbinate mucoperiosteal free graft and ear cartilage via open rhinoplasty approach. Material & Methods: From May 2008 to December 2010,7 patients who were suffered from nasal septal perforation underwent sandwich graft using ear cartilage and inferior turbinate mucoperiosteal free graft via open rhinoplasty approach. Results: Mean age was 45±10.1years (28~60 years old). We followed up 7 patients for 2 months after the surgery. Six of the 7 patients had a complete closure and one patient achieved incomplete closure. One patient who had incomplete closure was treated by primary closure again. Conclusions: Sandwich graft of inferior turbinate mucoperiosteal free graft and ear cartilage via open rhinoplasty approach showed high success rate and relatively easy surgical technique.

        Optimal Duration of Medical Treatment in Superior Mesenteric Artery Syndrome in Children

        신명석,김재영 대한의학회 2013 Journal of Korean medical science Vol.28 No.8

        The aim of this study was to investigate the outcome, and optimal duration of medical treatment in children with superior mesenteric artery syndrome (SMAS). Eighteen children with SMAS were retrospectively studied. The data reviewed included demographics,presenting symptoms, co-morbid conditions, clinical courses, nutritional status,treatments, and outcomes. The three most common symptoms were postprandial discomfort (67.7%), abdominal pain (61.1%), and early satiety (50%). The median duration of symptoms before diagnosis was 68 days. The most common co-morbid condition was weight loss (50%), followed by growth spurt (22.2%) and bile reflux gastropathy (16.7%). Body mass index (BMI) was normal in 72.2% of the patients. Medical management was successful in 13 patients (72.2%). The median duration of treatment was 45 days. Nine patients (50%) had good outcomes without recurrence, 5patients (27.8%) had moderate outcomes, and 4 patients (22.2%) had poor outcomes. A time limit of > 6 weeks for the duration of medical management tended to be associated with worse outcomes (P = 0.018). SMAS often developed in patients with normal BMI or no weight loss. Medical treatment has a high success rate, and children with SMAS should be treated medically for at least 6 weeks before surgical treatment is considered.

        Esophageal pH and Combined Impedance-pH Monitoring in Children

        신명석 대한소아소화기영양학회 2014 Pediatric gastroenterology, hepatology & nutrition Vol.17 No.1

        Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and children. This method allows for the detection of liquid, gas or mixed reflux in addition to acid, weakly acidic or weakly alkaline reflux. MII-pH monitoring can record the direction of flow and the height of reflux, which are useful parameters to identify an association between symptoms and reflux. However, the technique is limited by its high cost and the lack of normative data of MII-pH in the pediatric population. Despite certain limitations, MII-pH monitoring will become more common and gradually replace pH monitoring in the future, because pH monitoring is part of MII-pH.

        비강에 발생한 점막연관 림프조직 림프종 1예

        신명석,임상철 대한이비인후과학회 2006 대한이비인후과학회지 두경부외과학 Vol.49 No.12

        Most extranodal lymphomas arise in the gastrointestinal tract, but the other mucosal organs are rarely involved. We report a caseof primary mucosa-associated lymphoid tissue (MALT) lymphoma of the nasal cavity. A 65-year-old woman was refered to ourhospital with a history of prolonged epiphora in the left eye. Although nasal examination suggested normal except markedmucosal thickening of the inferior turbinate, partial inferior turbinectomy and biopsy revealed subepithelial infiltration of atypicallymphoid cells that stained for CD20, CD79a, and BCL-2;stained weakly for CD43, and this patient was finally diagnosedas having primary MALT lymphoma of the nasal cavity. This patient achieved complete remission after radiation therapy,and she remains free of disease for 6 months. (Korean J Otolaryngol 2006;49:1227-30)

        한글 두 글자 단어와 비단어의 명명에 글자 빈도, 글자 유형과 위치가 미치는 영향

        신명석,박창호 한국인지과학회 2024 인지과학 Vol.35 No.2

        글에서 글자는 단어를 구성하는 주요한 단위이다. 본 연구는 한글 글자의 속성(글자의 빈도, 모음의 유형, 받침의 유무, 글자의 위치)이 단어와 비단어의 명명에 영향을 미치는지를 알아보고자 하였다. 선형혼합효과분석 결과 단어는 첫째 글자의 빈도가 증가할수록 명명시간이 감소하였으며, 첫째 글자에 받침이 있을 때 명명시간이 감소하였다. 또한, 단어가 횡모음 유형일 때보다 종모음 유형일 때 명명 정확률이 더 높았으며 첫째 글자에 받침이 없을 때보다 있을 때 명명시간이 감소하였다. 비단어는 첫째 글자의 빈도와 둘째 글자의 빈도가 각각 증가할수록 명명시간이 감소하였으며 명명 정확률이 더 높았다. 비단어도 횡모음 유형일 때보다 종모음 유형일 때 명명 정확률이 더 높았다. 본 연구에서 둘째 글자의 빈도 효과는 단어와 비단어에 따라 달랐지만, 첫째 글자의 빈도효과와 모음 유형의 효과는 일관되게 나타났다. 시각단어재인에 대해 연구 결과의 함의를 논의하였다. This study investigated how syllable-level variables such as syllable frequency, syllable (i.e. vowel) type, presence of final consonants (i.e. batchim) and syllable position influence naming of both words and pseudo-words. The results of the linear mixed-effects model analysis showed that, for words, naming time decreased as the frequency of the first syllable increased, and when the first syllable had a final consonant. Additionally, words were named more accurately when they had vertical vowels compared to horizontal vowels. For pseudo-words, naming time decreased and accuracy rate increased as the frequency of the first or the second syllable increased. Furthermore, pseudo-words were named more accurately when they had vertical vowels compared to horizontal vowels. These results suggest that while the frequency of the second syllable had differential effects between words and pseudo-words, the frequency of the first syllable and the syllable type had consistent effects for both words and pseudo-words. The implications of this study were discussed concerning visual word recognition processing.
