An auditory experiments for the phonetic value of the last consonants when its signal is transmitted through the amplifier from the last to the first, shortly speaking, time reversed waveform, were done for the 14 Korean consonants. Then the last consonant becomes to the first consonant in the time reversed waveform. The listeners who heard the 14 reversed consonants have recorded the phonetic value being heard. We analyzed these results by the method of articulation and the position of articulation. By the results, the phonetic value of the last consonants /n/, /l/ and /m/ is the same as the first consonants. Last consonant /d/ is heard like first consonant /n/. Last consonant /ng/ is heard like first consonant /m/. Last consonants /k/ and /b/ don't have any particular phonetic values. These results were tested by the experiments and were analyzed by the principle of articulation.

만성중이염은 현재 그 빈도가 줄어드는 추세에 있으나 아직도 이과 영역에서 큰 비중을 차지하는 질환이다. 또한 청력개선, 정상구조의 보존, 병변 제거의 목적을 위하여 대부분 수술적 요법이 필요하게 된다. 이에 저자들은 본 병원에서 시행한 만성 중이염 451예, 남자 238예, 여자 213예. 진주종성 중이염 170예, 비진주종성 중이염 273예에 대한 수술시 소견에 대한 임상 통계적 관찰을 한 바, 다음과 같은 결과를 얻었다. 1) 관찰대상을 술식별로 분류하면 진주종성 중이염과 비진주종성 중이염의 비가 $\circled1$ Myningoplasty ; 19.1% : 0%, $\circled2$ Tympanoplasty without mastoidectomy ; 34.5% : 14.4%, $\circled3$ Tympanoplasty with mastoidectomy ; 3.0% :12.1% 이었다. 2) 고막천공부위는, 진주종성 중이염과 비진주종성 중이염의 비가 변연부천공이 10.1% : 5.5%, 상고실천공이 38.8% : 1.4%, 중심부천증이 12.9% : 47.3%, 전천공이 32.5% : 39.6%, 고막유착이 5.6% : 6.2% 을 보였다. 3) 이소골의 상태는 진주종성중이염과 비진주종성 중이염의 비가, 모든 이소골의 손실은 26.6% : 4.3%, 모든 이소골이 정상에 가까운 예는 16.6% : 69.3%, 가장 병변이 심했던 침골 이상은 76.9% : 24.8% 를 보였다. 4) 중이강 점막소견은 진주종성 중이염과 비진주종성 중이염의 비가, 정상에 가까운 예가 16.7% : 47.0%, 병적 소견을 보인 예가 83.3% : 53.0% 이었다. 5) 진주종성 중이염과, 비진주종성 중이염에서의 안면신경관노출은 2.2% : 0.3%, 뇌막노출은 9.5% : 2.9%, 횡정맥동노출은 5.0% : 1.1%, 미로누공은 1.7% : 0% 이었다.lant, engineering service business can be said "The Software of Total Industry." Engineering service is what is called a higher business which offers specialized engineering know-how and experience. Engineering service compaines offer Its specialized knowledge and experience to government, industry and commerce. Whether the task is to modernize plant equipment, to design a building or to manage construction, an engineering company will develop and implement the most appropriate and cost effective solution. Clients use the engineering service of firm knowing that the engineer′s professional judgement is not influenced or biased by other commercial affiliations. While benefiting from the diverse experience that professional engineers can apply to a specific problem, government and industry also reduce the need for permanent in-house engineering staff. Engineering firms may be specialized or multi-disciplinary.도말표본에서와 같이 제 14 일 이전에는 호중구가, 그 이후에는 단핵구가 주종을 이루었다.>18.9dB

본 논문에서는 한국어 단어를 산출하는 과정에서 음절 내 부호화 과정을 규명하기 위해 2개의 단어번역과제 실험을 수행하였다. 한국어 산출에서 종성점화효과를 검증한 실험 1에서 종성 반복 조건과 통제조건 간에 단어번역시간에서 차이를 보이지 않았다. 반면에 실험 2에서는 11ms의 부적인 중성점화효과를 보였다. 구민모와 남기춘(2009)과 본 연구의 결과를 종합하면, 다음과 같은 결론에 도달한다: (1) 한국어 산출 어휘집에서 음절은 "음절체+종성"의 위계적인 내적 구조로 표상된다. (2) 음절 내 부호화는 음절체와 종성이 계열적인 순서로 진행된다. (3) 음절체를 구성하는 초성과 중성이 계열적인 순서로 음절구조에 삽입된다.

Chronic granulomatous disease in childhood is a rare inheritable disorder of phagocytic cells in which defective production of the reactive intermediates of oxygen predisposes the patient to severe recuring pyogenic infections. The lung is the most common site of infection and pulmonary disease is the primary cause of death for greater than 50% of children with chronic granulomatous disease. Although the role of surgery in management of this disease remains undefined, rapid diagnosis of the underlying pulmonary problem is crucial to determine the most appropriate antimicrobial therapy and surgical techniques such as lobectomy of involved areas lead to more rapid recovery and thus allow the antibiotics to be more efficacious in these cases. We have treated a one month old male baby who had the chronic granulomatous disease with pulmonary infection. Wide surgical resection of the affected lobe and use of antibiotics and antifungals were carried out with good clinical results. He was well after the operation.

The purpose of this study was to develop Korean Consonant Perception Test (KCPT), that is a phonemic level including elementary data to evaluate speech and consonant perception ability of the normal and the hearing impaired qualitatively and quantitatively. KCPT was completed with meaningful monosyllabic words out of possible all Korean monosyllabic words, considering articulation characteristics, the degree of difficulty, and the frequency of the phonemic appearance, after assembling a tentative initial and final consonants testing items using four multiple-choice method which were applied to the seven final consonant regulation and controlled with the familiarity of the target words. Conclusively, the final three hundred items were developed including two- and one-hundred items for initial and final testing items, respectively, with the evaluation of the 20 normal hearing adults. Through this process, the final KCPT was composed upon the colloquial frequency following identification of no speakers' variances statistically and elimination of the highly difficult items. The 30 hearing impaired were tested with KCPT and found that the half lists, A and B, were not different statistically and the initial and final testing items were appropriate for evaluating initial and final consonants, respectively.

Motivated by the fact that cluster reduction strategies such as inserting a vowel or deleting a consonant in resolving English complex clusters differ depending on studies, this paper investigates the repair strategies employed by Korean EFL students. A total of 60 college students participated in the present study and the participants' production of English voiceless word-initial and word-final clusters was measured using the materials designed for this study. It has been shown that prosodic positions such as onset and coda and the number of cluster sequences influenced cluster reduction strategies. The error rates of both insertion and deletion were noticeably higher in the coda position than in the onset position and both insertion and deletion error rates were higher in triconsonatal cluster than in biconsonantal cluster sequences. Overall, the insertion rate was higher than the deletion rate. However, the deletion rate was significantly higher than the insertion rate in triconsonantal coda cluster sequences. Because of this, the deletion rate was higher than the insertion rate for triconsonantal cluster sequences across onset and coda. Also, the high deletion rate of triconsonantal coda clusters contributed to the high deletion rate for the coda clusters in general.

한국어 CVC 음절의 하위 단위는 초성자음과 모음을 포함하는 음절체(body)와 종성자음(coda)으로 이루어져 있고, 영어 음절은 초성(onset)과, 모음과 종성자음을 포함하는 각운(rime)으로 이루어져 있다고 한다. 본 연구에서는 한국인이 영어의 음절을 한국어 음절 정보처리 방법으로 정보처리 하는지를 알아보고자 하였다 실험 조건으로는 음절체 일치 조건(예, 각-감, cap-cat), 각운 일치 조건(예, 남감, pat-cat), 그리고 두 자음 일치 통제조건(예, 김-감, cut-cat)과 무관련 통제 조건(예, ***-감, ***-cat)이 사용되었다. 실험 과제로는 점화 어휘판단 과제(primed lexical decision task)를 수행하였다. 만약 음절체 일치 조건에서의 점화효과가 각운 일치 조건에서의 점화효과보다 크다면 한국인의 음절분절 단위가 음절체-종성(body-coda) 구조일 것으로 예상할 수 있고 각운 조건에서의 점화효과가 더 크다면 그 단위가 초성-각운(onset-rime)구조일 것으로 예상할 수 있다. 실험 결과, 한국어 음절의 경우 각운 일치 조건의 점화 효과가 음절체 일치 조건의 점화 효과보다 크게 나타나 음절체-종성 구조로의 하위 단위 분석을 지지했다. 그러나 영어의 경우에는 각운 일치 조건의 점화 효과가 음절체 일치 조건의 점화 효과보다 크게 나타나 초성-각운 구조로의 분석을 지지하였다. 따라서 한국인이 시각 단어를 재인할 때에는 언어 특정적인 분석을 수행한다는 결과를 얻었다.

Due to a large number of classes in Hangul character recognition, it is usual to use the six-type preclassification stage. After the preclassification, the first consonent, vowel, and last consonent can be classified separately. Though each of three components has a few of classes, classification errors occurs often due to shape similarity such as 'ㅔ' and 'ㅖ'. So this paper proposes a hierarchical recognition method which adopts multi-stage tree structures for each of 6-types. In addition, to reduce the interference among three components, the method uses the recognition results of first consonents and vowel as features of vowel classifier. The recognition accuracy for the test set of PHD08 database was 98.96%.
