Objectives: Although language sample analysis is essential for language evaluation, it is not widely conducted due to time constraints and difficulties in analysis. This study was conducted to evaluate the Korean-Automatic Language System (K-ALAS), which was developed to support language sample analysis. Methods: 50 language samples of young children aged 2 to 6 were analyzed by K-ALAS and a language analysis expert. The percentage agreement of the analysis results between K-ALAS and the expert on Eojeol, words, and morpheme, which are the basic units of language measurement, were calculated, and t-test and Pearson correlation analysis were conducted on the main language measures (MLUe, MLUw, MLUm, NTJ, NTE, NDJ, NDE, NTW, NDW, TTR) measured by K-ALAS and the expert. Results: The percentage agreement of the eogeol, word, and morpheme analysis between K-ALAS and the expert, was found to be very high at 97.87-99.88%, and the t-test results showed that there was no significant difference between all language measures measured by K-ALAS and the expert, and the result of correlation analysis was also very high with r = .972-1.000. Conclusion: This study confirmed that K-ALAS analyze language samples and measures the main language measures very accurately. We discussed the implications of clinical use of K-ALAS in relation to language diagnosis and intervention.

Objectives: Connective endings play an important role not only in producing complex sentences but also in logically expressing thoughts. The purpose of this study was to examine the development of the use of connective endings in the spontaneous language of children aged 2-6. Methods: A total of 250 children aged 2 to 6 participated in the study, in groups of 50 by age group. Spontaneous language samples were collected between the examiner and the children via a semi-structured conversation procedure in which the topic of conversation and the examiner’s conversational behavior were controlled. The total number of connective endings, number of connective endings by subcategory and by subtype were measured by extracting 50 utterances from each child’s language sample. Results: (1) The total number of connective endings (CE) and the numbers of the three CE categories increased significantly according to age and the significant differences were observed before and after the age of 4. (2) In the subtypes of CE, auxiliary and closing connective endings were the most frequently used in all age groups, and closing connective endings significantly increased from 2 to 4 years old. However, there was no significant difference in the use of auxiliary connective endings according to age because they were used frequently from the age of 2. (3) The total number of CE (39.4%), and the subordinate category (40.9%) among the three CE categories; cause (31.3%), purpose (9.6%), choice (5.5%), list (2.4%) among the subtypes of CE explained age. Conclusion: The study confirmed that the developmental pattern of the use of connective endings in spontaneous language of the children aged 2-6. We discussed the academic and clinical implication of the result and suggest the needs of the follow-up study.

이윤경,조정수 대한수학교육학회 2015 수학교육학연구 Vol.25 No.3

This study examined the types of abduction appeared in the exploration activities of ‘law of large numbers’ in order to figure out relation between statistical reasoning and abduction. When the classroom discourse of students was analyzed by Peirce’s abduction, Eco’s abduction type and Toulmin’s argument pattern, students used overcoded abduction the most in the discourse of abduction. However, there composed a low percent of undercoded abduction leading to various thinking, and creative abduction used to make new principles or theories. By the CAS calculators used in the process of reasoning, students were provided with empirical context to understand the concept of abstract probability, through which they actively participated in the argumentation centered on the reasoning. As a result, it was found that not only to understand the abduction, but to build statistical context with tools in the learning of statistical reasoning is important. 본 연구는 통계적 추론과 가추법의 관계를 알아보기 위하여 ‘큰 수의 법칙’ 탐구 활동에서 나타난 가추법의 유형을 살펴보았다. Peirce의 가추법, Eco의 가추법 유형, Toulmin의 논증패턴을 바탕으로 통계 수업담화를 분석한 결과, 가추법에 해당하는 수업담화에는 과대 코드화된 가추법이 가장 많이 나타났다. 반면에 학생들의 다양한 사고를 유도하는 과소 코드화된 가추법과 새로운 법칙이나 이론을 만드는 창조적 가추법은 낮은 비율로 나타났다. 추론과정에 사용된 계산기는 추상적 확률 개념을 이해하기 위한 경험적 맥락을 통해 학생들이 추론을 중심으로 한 논증과정에 적극적으로 참여하게 하였다. 이러한 연구 결과를 통해 통계 수업에서는 가추법에 대한 이해와 함께 도구를 이용한 통계적 맥락 형성이 중요함을 알 수 있었다.

본 연구는 다양성에 대한 국·내외 연구를 종합적으로 분석하여 팀구성원의 심층적 다양성이 혁신행동에 미치는 영향에 대해 분석하기 위한 몇 가지 연구명제를 도출하였다. 기존에 주로 수행되었던 연구가 가시적인 인구통계적 다양성에 초점을 두고 있는데 따라, 비가시적이고 심층적인 다양성의 효과를 분석하기 위해, 심층적 다양성에 대한 문헌연구를 통하여, 그 범위와 연구결과에 대해 분석하였고, 국내의 연구 상황도 살펴보았다. 이에 따라 집단에서 존재하는 성별다양성, 인지방식다양성, 목표지향다양성이 성과에 영향을 미치는 과정에서 집단 성찰성과의 매개효과와 과업복잡성의 조절효과에 대한 기능을 탐색해 보았다. 제시된 명제를 바탕으로 이론적 의미와 향후 연구방향을 제시하였다. Diversity is important issue on business today. Diversity can enhance as well as disrupt team performance. As the work force diversifies in cultural background and gender and companies become more reliant on cross-functional teams, team diversity is on the agenda of research and practice more than ever before. Diversity poses complex challenges, however, because it can have positive as well as negative effects on team performance. This has led to the conclusion that the key challenge for diversity research is to identify the contingencies of these effects. The processes underlying the positive and negative influences of diversity are well-documented: diversity may be an asset as an informational resource, and a liability as a source of interpersonal tension and intergroup biases. Identifying the factors that determine which of these processes dominate in a diverse group has proven to be challenging. This study analyzed comprehensively on diversity in work to research the impact of team member's deep-level diversity on innovation behavior and we propose some research propositions. Existing researches on diversity have focused on demographic attributes(age, sex, age, ethnic, race etc.). So through literature study, we examined a range of deep-level diversity and a relation between deep-level diversity and performance. Therefore we propose the following hypothesis. 1) Personality(agreeableness, conscientiousness, openness to experience) diversity and goal orientation diversity will be negatively related to innovation behavior and this relationship will be mediated by reflexivity. And Task complexity will strengthen the relationship between diversity(personality, goal orientation) and reflexivity. 2) Personality(extraversion, emotional stability) diversity and cognitive style diversity will be positively related to innovation behavior and this relationship will be mediated by reflexivity. And Task complexity will strengthen the relationship between diversity(personality and cognitive style) and reflexivity.

이윤경,김현정,윤희영,최창민,오연목,이상도,임채만,김우성,고윤석,이재승 대한의학회 2016 Journal of Korean medical science Vol.31 No.11

Pulmonary artery sarcomas (PAS) are rare malignant neoplasms. Right heart failure due to tumour location is the main cause of death in PAS patients. The hemodynamic influence of PAS may effect prognosis, but this has not been proven. We aimed to identify the clinical characteristics and prognostic factors of PAS in Korea, their association with pulmonary hypertension (PH). PAS patients treated at the Asan Medical Center between 2000 and 2014 were reviewed. We examined demographic characteristics, diagnostic and treatment modalities. Potential prognostic factors were evaluated by univariate and multivariate analysis. Twenty patients were diagnosed with PAS. Ten patients were male, the median age was 54 years (range, 33–75 years). The most common symptom observed was dyspnea (65%). The most common histologic type was spindle cell sarcoma (30%). Ten patients had a presumptive diagnosis of pulmonary embolism (PE) and received anticoagulation therapy. Seventeen patients underwent surgery, but only 5 patients had complete resection. Eleven patients received post-operative treatment (chemotherapy = 3, radiotherapy = 5, chemoradiotherapy = 3). PH was observed in 12 patients before treatment and in 6 patients after treatment. Overall median survival was 24 months. Post-treatment PH was associated with poor prognosis (HR 9.501, 95% CI 1.79–50.32; P = 0.008) while chemotherapy was negatively associated with mortality (HR 0.102, 95% CI 0.013–0.826; P = 0.032) in univariate analysis. Post-treatment PH was also associated with poor prognosis in multivariate analysis (HR 5.7, 95% CI 1.08–30.91; P = 0.041). PAS patients are frequently misdiagnosed with PE in Korea. Post-treatment PH is associated with a poor prognosis.

생쥐 간의 Triacylglycerol 생합성에 있어서 Palmitoylcarnitine의 지방산 공여체로서의 역할

이윤경,정진성,조기승,Lee, Youn-Kyung,Chung, Jin-Sung,Cho, Key-Seung 생화학분자생물학회 1986 한국생화학회지 Vol.19 No.3

$^{14}C$-Palmitoylcarnitine을 생쥐 간 균질물과 반응시킨 결과 1시간 후 33%, 3시간 후에 51%, 6시간 후에 최고 61%의 가수분해를 나타냄으로서, 동물체의 간이 acylcarnitine의 중요한 대사부위 임을 나타내 주었다. $^{14}C$-Palmitoylcarnitine ($^{14}C$-pal. carn)에 의한 $^{14}C$-triacylglycerol ($^{14}C$-TG)의 생합성은 0.1 M tris-HCl buffer, pH 7.4 및 반응온도 $20^{\circ}C$에서 각각 최고의 합성율을 나타냈고, ATP, coenzyme A (CoASH), $Ca^{2+}$ 및 $Mg^{2+}$의 cofactor 등은 triacylglycerol 생 합성계에 전혀 영향을 끼치지 않았으며, 이들은 phospholipid 생성계를 활성화시키는 것으로 나타났다. 동일 조건하에서 (U-$^{14}C$)-palmitic acid에 의한 중성지 질의 생합성을 비교하여 본 결과, 반응온도는 $20^{\circ}C$가 적정온도였고, 이 반응계는 ATP, CoASH 및 $Mg^{2+}$의 cofactor를 필요로 했는데 반응시간에 따라 차이를 보여주었다. 즉, 30분 반응에서는 cofactor 존재하에서 $^{14}C$-TG 생성이 증가를 보였으나, 3시간 반응에서는 cofactor가 존재하지 않은 대조구보다 $^{14}C$-phospholipids 생성이 증가함을 나타냈다. 간 균질물의 여러 분획에 있어서 $^{14}C$-pal. carn에 의한 $^{14}C$-TG의 생성을 비교해 본 결과, microsomal cytosol 분획에서 가장 높은 triacylglycerol와 diacylglycerol의 생성율을 보였고, 다음이 mitochondria 분획, nuclei와 cell debris 분획 순이었다. 이상의 결과로 보아 palmitoylcarnitine은 microsome에서 cofactor의 도움 없이 직접 acyl group을 이전시켜 중성지질을 생성하는 것을 확인할 수 있었다. It was confirmed that the important metabolic site of acylcarnitine was liver in mamals from the results of its hydrolysis, in which percent of hydrolysis was 33%, 51 %, and 61% from incubation for 1 h, 3 h, and 6 h, respectively. In the triacylglycerol biosynthesis from (U-$^{14}C$)-palmitolyl-DL-carnitine, the optimum conditions were obtained in 0.1 M tris-HCl buffer, pH 7.4 and $20^{\circ}C$ of incubation temperature. The effect of cofactors, such as $Ca^{2+}$, $Mg^{2+}$, ATP, and coenzyme A reduced the formation of triacylglycerol, rather increased the formation of phospholipid. This result showed that triacylglycerol synthesis from palmitolycarnitine did not need any cofactors. The comparison of the triacylglycerol biosynthesis from (U-$^{14}C$)-palmitic acid with that of (U-$^{14}C$)-palmitoyl-DL-carnitine showed the same optimum conditons in pH and incubation temperature. But in cofactors effect, tracylglycerol synthesis from $^{14}C$-palmitic acid was stimulated in the presence of ATP, CoASH, and $Mg^{2+}$ in 30 min incubation when it was compared with or without of cofactors. When the incubation period was prolonged to 3 h, triacylglycerol synthesis was reduced and, on the other hand, phospholipid synthesis was increased significantly more than 6 times. With the results from the different cell fractions, the highest triacylglycerol biosynthesis was prepresented with microsomal cytosol fraction and next was in order of mitochondrial fraction and nuclei cell debris fraction. As conclusion, firstly, it could be postulated that the direct mobilization of acyl group from palmitoylcarnitine to monoacylglycerol and diacylglycerol resulted triacylglycerol synthesis. Secondly, free fatty acid from hydrolysis of palmitoylcarnitine might from acyl CoA in the presence of ATP and CoASH, and continued the sequencial reactions with diacylglycerol and with Iysophospholipid to form the triacylglycerol and phospholipid, respectively.
