본 연구는 노화로 인한 인지 저하의 발견과 치매 환자의 평가를 위하여 청장년층부터 노인의 생성 이름대기 규준을 마련하고 연령, 성별 그리고 교육수준에 따른 수행력의 차이를 살펴보고자 하는데 목적이 있다. 이를 위해 국내의 40대에서 80대 성인 145명을 대상으로 생성이름대기 과제를 실시하였다. 본 연구 결과, 생성이름대기 전체 평균 점수는 의미 유창성 수행 점수가 음소 유창성 수행 점수보다 다소 높은 양상을 보였으나 연령대별로 다른 양상을 보였다. 첫째, 연령에 따른 차이는 40대와 50대 성인이 70대, 80대 각각 비교하여 유의하게 높은 수행을 보이는 것으로 나타났다. 둘째, 성별에 따른 차이는 70대에서 ‘동물’, ‘탈 것’, /ㅅ/, /ㅂ/에서 남성이 여성보다 유의하게 높게 나타났다. 셋째, 교육수준에 따른 차이는 80대를 제외한 모든 연령대에서 의미 유창성 보다는 음소 유창성 과제에서 유의한 차이가 나타났다. 생성이름대기 과제 수행력에서 성별 보다는 연령과 교육 수준이 더 유의한 영향을 미치며, 의미 유창성 과제보다는 음소 유창성 과제가 집단 간의 더 유의한 차이를 보여주었다. 넷째, 생성이름대기 6개의 과제 간의 상관성은 매우 유의미하였으며, 음소유창성 과제가 보다 상관성이 높은 것으로 나타났다. 이 연구결과가 임상적으로 보다 의미있게 활용되기 위해서는 대상자 특성과 수행력 평가 방법 차원에서 지속 연구되어야 할 것이다. Purpose: The performance of verbal fluency is closely related to working memory and is known to be sensitive to cognitive decline the elderly. The purpose of this preliminary study is to establish the criteria for the generation of the elderly from the youth to the elderly and to examine the differences in performance according to age, gender and education level. This will be used to detect cognitive decline caused by aging and to differentiate between dementia patients from normal aging. Methods: 145 adults in their 40s and 80s participated. The verbal fluency task includes semantic fluency (e.g., animal naming) and phonemic fluency in specific letter (e.g., /k/ ). The total number of words generated in 1 minute for the name of semantic category(‘animals, vehiecles, fruits’), and the letters (/ㄱ/, /ㅅ/, and /ㅂ/). Results: First, a result of this study, the overall average score of the name generation was lowered in order of animal , fruit , vehicle , /g/, /s/, and /b/. Age-specific differences showed that adults in their 40s and 50s performed significantly higher compared to those in their 70s and 80s, respectively. Second, gender differences were significantly higher for men in their 70s than for women in animal , vehicle , /s/, and /b/. Third, differences in education level showed significant differences in phonemic fluency tasks rather than semantic fluency in all age groups except those in their 80s. Age and educational level have a more significant effect on ability than gender in the performance of verbal fluency, and phoneme fluency tasks have shown more significant differences between groups than semantic fluency tasks. Finally, there was a significant correlation between types of verbal fluency tasks. Discussion: It is meaningful that some of the findings provided data that could be the preliminary norm for verbal fluency ability in people in their 40s and 80s. However, the number of younger people and senior citizens in a broader age group should be increased to study.

형태통사적 범주에 따른 일반아동(4-6세)의 의문사 이해 발달

손은남(Eun Nam Sohn),이우진(Woo Jin Lee) 한국언어치료학회 2011 言語治療硏究 Vol.20 No.1

This preliminary study investigated the interrogative developmental aspects in accordance with formative grammatical category in Korean children, aged four to six. Thirty subjects were studied, 10 per each age group. Sixty-three interrogatives in the aspect of formative grammar, which lack descriptive features were selectedfor this study. This research was conducted by asking related questions after presenting pictures with no characters and while simultaneously telling a story. The results showed that the correct response rate for interrogatives was higher as subjects ages increased. In addition, there were significant differences ondevelopment of sub-interrogatives between the four-year-old children group and the other two groups.

3-6세 아동의 의문사 이해 발달에 대한 연구

손은남(Eun Nam Sohn) 한국언어치료학회 2013 言語治療硏究 Vol.22 No.3

This study investigated the development of children's comprehension of contractions, variations and interrogative repetition. Sixty subjects were selected for this study with 15 in each age group from three to six. Twenty-three interrogatives were chosen from normal interrogatives or in the category of contraction, variation or interrogative repetition, excluding combination and interrogative lexical phrases. We practiced our research by asking related questions after presenting textless pictures. In the meantime, no story or information was provided to the children regarding the pictures.As a result, the correct response rate for interrogatives increased among older subjects. Interrogative and contraction interrogative marked a higher response rate from children aged three or four and nearly 100% at age six. On the other hand, children aged three or four showed a lower response rate in repetition interrogatives and children aged six could not reach a 100% response rate. Therefore we can understand that interrogatives and contraction interrogatives are acquired prior to repetition interrogative.

치매의 의사소통 특성에 관한 연구

손은남(Eun Nam Sohn) 한국언어치료학회 2015 言語治療硏究 Vol.24 No.4

Purpose: Based on the growth of the elderly population, basic research and intervention studies on dementia haveincreased in the field of Speech-Language Pathology. However, there are no guidelines regarding diagnostic methods for dementia or personalized language intervention programs. This study aims to analyze the research findings oncommunication skills of dementia in Korea and to discuss which area lacks research. Method: “Dementia” and“Alzheimer's” were used as keywords in a search of computerized data bases. Among results, a total of 55 papers were selected. Results: Trends from the early 2000s showed research on dementia had a tendency to increase gradually. In terms of subjects, Alzheimer's dementia was as high as 75%. In terms of research methods, research study shows 71% by observation and cross-sectional study shows 84% by data collection timing. Among research topics, expressive ability, receptive ability and communicative ability showed 76%, 13% and 11% respectively. In particular, naming studies had a rate of 27%, which was the highest among all variables. Conclusion: As a result of analyzing literature related to the communicative ability of dementia, we found that all subjects, methods, and topics of study were very biased. The result was consistent with the general view that naming ability of dementia patients is affected by damage to the lexical semantic system. They showed lower discourse ability than normal performance and also differences in severity. There are many studies that investigate semantic corruption with the variables of naming and word definition. Therefore, more research on language comprehension and syntactic aspects are required. It is also necessary to identify a longitudinal study to clarify the language change in severity cases of dementia.

The purpose of the study was to compare the capacity to retell stories of adults with different ages. Thirty-three subjects were grouped by age, 13 younger aged people(group A) and 20 older people(group B). Narrative speech was analyzed both for expression of plot line, story theme and the protagonists misadventures in the story; and for expression of first, middle and the final portion of the story. The group A produced plot line, thematic content, and protagonists misadventure more frequently than the group B. The group A also recalled information units of all three first, middle, and end portions of the story.

본 연구는 매체순환연소공정용 산소전달입자로서 CaSnO₃ 입자의 타당성을 조사하기 위해 수행하였다. CaSnO₃은 페롭스카이트 구조를 가지고, 반복되는 환원-산화 반응 후에도 구조적안정성을 보였다. 산소전달량은 환원 반응 시 결정 구조 변화를 통해 계산된 이론 수치와 거의 동일한 15.4 wt%를 가졌다. 10번의 환원과 산화 반응 후에, 산소전달량과 산소전달속도는 작동 온도에서 일정하게 유지되었다. 결론적으로, CaSnO₃ 입자는 CLC의 산소 운반체로서 좋은 대체물질이 될 수 있다고 판단하였다. This study investigated the feasibility of CaSnO₃ particles as an oxygen carrier in chemical looping combustion (CLC). CaSnO₃ particles had a perovskite crystal structure and showed the structural stability after repeated reduction-oxidation reactions. The oxygen transfer capacity was 15.4 wt% almost the same as the calculated theoretical value from the crystal structure transformation during reduction. After 10^th cycles of reduction and oxidation, the oxygen transfer capacity and rate were still maintained constantly at an operating temperature. In conclusion, CaSnO₃ particles could be a good alternative material as an oxygen carrier in CLC.
