This study investigated the correlation between media use and language development in 5-year-olds and whether artificial intelligence can be used to predict the level of language development in 5-year-olds according to media use. For the data, the degree of use of the media, the time of use, and the score of language development were used in the 6th data of the Korean Children’s Panel. The data were analyzed through correlation analysis of SPSS 27.0 and Brightics AI of Samsung SDS. As a result of this study, first, there was a statistically significant negative correlation between language development in 5-year-olds with the use of personal game consoles(r=-.065, *p<.05) and mobile phones(r=-.066, *p<.05) and play time using media(r=-.138, **p<.01). Second, the prediction of the level of language development in 5-year-olds according to media use using artificial intelligence showed low performance at 33.93%. In other words, the degree of media use and usage time in 5-year-olds negatively affect language development, but it is difficult to predict language development only by the degree of media use. Therefore, based on the results of this study, it is believed that guidelines for media use that do not prevent children's language development are needed, and it is expected that the continuously developing artificial intelligence technology will be used as a tool to predict and diagnose the level of development of children.

Organ-specific transcription factors and promoters are likely to be useful for testing the effects of changes in expression of regulatory genes related to agronomical traits in rice. Here, we analyze the transcriptome of 7 tissues or organs of Oryza sativa L. cv. Dongjin, callus, regenerating callus, germinating seed, leaf, root, and flower (before and after pollination), using a rice 3′ ORF tilling microarray. The ratio of standard deviation to the mean of microarray intensities was used to distinguish between organ-specific and constitutively expressed genes. Accordingly, genes are classified into highly variable, variable, and constitutive groups. To isolate organ-specific promoters, several genes were selected and validated in planta using reporter gene analysis. We found that the Os01g0702500, Os11g0211800, and Os01g0257300 promoters to be active in calli, germinating seeds, and roots, respectively. The Os08g0546300 promoter was able to drive transgene expression in various organs of mature flowers, such as the anther, lemma, and palea, whereas the Os03g0369100 promoter was only active in the anther. Lastly, the Os09g0553100 promoter induced high levels of reporter gene expression in all organs. These gene expression data from representative organs could provide a framework for large dataset collections and subsequent profiling via organ/tissue subdivision might be more efficient for identifying appropriate promoters.

홍대용의『간정필담(乾淨筆譚)』이본고(異本考)

채송화 국문학회 2018 국문학연구 Vol.0 No.37

This article introduces the current status of Hong, Dae-yong's written conversation variants and divides it into three major groups. Which are 1. Hoeurok(會友錄) group variants, 2 Ganjeongpildam(乾淨筆譚) in Yeonhwi(燕彙), 3. Ganjeongpildam(乾淨衕筆談) in Damheonseo(湛軒書). This article focused on different characteristics between groups 2 Ganjeongpildam in Yeonhwi and 3. Ganjeongpildam in Damheonseo. A total of eight variants are currently available for Ganjeongpildam. It seems to have been circulated as a set together with Yeonhaengjapgi(燕行雜記). Ganjeongpildam is a solitary written conversation written for the purpose of publicizing to the unspecified number of people in Chosun. It provides the necessary beforehand information in preface of the written conversation, and it adds a lot of ephemeral writings with Hangzhou(杭州) scholars so that the process of deepening friendship for a short period of time is convincingly drawn. In addition, it revealed that Hong, Dae Yong limited the range of his dissemination to Chosun through passages expressing Ming Dynasty ruined country’s consciousness. Ganjeongdongpildam has more contents than Ganjeongpildam, This book can be said to be a treasure trove of written conversation, which Hong, Dae-yong tried to record as many stories as possible. Various artifacts and institutions of Chosun and Qing Dynasty were introduced throughout the written conversation, and characters with various nationalities and identities are appearing and their true aspects are well portrayed. In addition, Hong, Dae Yong affirmed the reign of Qing Dynasty and appreciated the real diplomatic relations with Chosun. In this way, there is a lot of interesting material in Ganjeongpildam, and it can be said that Ganjeongpildam is closer to that of Ganjeongdonghoeurok(乾淨衕會友錄), Ganjeongrok(乾淨錄) which is early variant of written conversation. 본고는 현전하는 홍대용 필담 이본들을 망라하여 그 현황을 소개하고, 이를 크게 세 계열로 나누었다. ⑴ 『회우록』계 이본, ⑵ 『연휘』 중 『간정필담』, ⑶ 『담헌서』 중 『간정동필담』이 그것이다. 그 중 계열⑵에 속하는 『간정필담』과 계열⑶인 『간정동필담』의 차이에 초점을 맞추어 그 특징을 분석하였다. 총 8종의 이본이 현존하는 『간정필담』은 『연행잡기』와 한 세트를 이루어 유통되었던 것으로 보인다. 『간정필담』은 조선 내의 불특정 다수에게 공개를 목적으로 저술된 단독 필담집이다. 필담 서두에서 필요한 사전 정보들을 제공하고 있으며, 항주 선비들과 주고받은 서간문들을 대폭 추가하여 짧은 기간 동안 우정이 깊어지는 과정을 설득력 있게 그려내고 있다. 또한, 명나라 유민의식이 표출되는 대목들을 통해 홍대용이 그 유포 범위를 조선으로 한정한 저작임을 밝혔다. 『간정동필담』은 『간정필담』보다 분량이 더 많으며, 홍대용이 필담 당시 나누었던 이야기들을 최대한 수록하고자 노력한 필담 소재의 보고(寶庫)라고 할 수 있다. 조선과 청나라의 다양한 문물과 제도들이 필담 전편에 걸쳐 소개되었고, 다양한 신분과 국적을 가진 등장인물들이 등장하고 있으며 그 진솔한 면모가 잘 묘사되어 있다. 또한, 홍대용은 청나라의 치세를 긍정하며 조선과의 실제 외교 관계 또한 긍정적으로 평가했다. 이와 같이 흥미로운 소재가 무궁무진한 『간정동필담』은 필담 초기본인 『간정동회우록(乾淨衕會友錄)』이나 『간정록(乾淨錄)』에 더욱 근접한 이본이라고 할 수 있다.

Pre-mRNA splicing further increases protein diversity acquired through evolution. The underlying driving forces for this phenomenon are unknown, especially in terms of gene expres-sion. A rice alternatively spliced transcript detection microarray (ASDM) and RNA sequencing (RNA-Seq) were applied to differentiate the transcriptome of 4 representative organs of Oryza sativa L. cv. Ilmi: leaves, roots, 1-cm-stage panicles and young seeds at 21 days after pollination. Comparison of data obtained by microarray and RNA-Seq showed a bell-shaped distribution and a co-lineation for highly expressed genes. Transcripts were classified according to the degree of organ enrichment using a coefficient value (CV, the ratio of the standard deviation to the mean values): highly variable (CVI), variable (CVII), and constitutive (CVIII) groups. A higher index of the portion of loci with alternatively spliced transcripts in a group (IAST) value was observed for the constitutive group. Genes of the highly variable group showed the characteristics of the examined organs, and alternatively spliced transcripts tended to exhibit the same organ specificity or less organ preferences, with avoidance of ‘organ distinctness’. In addition, within a locus, a tendency of higher expression was found for transcripts with a longer coding sequence (CDS), and a spliced intron was the most commonly found type of alternative splicing for an extended CDS. Thus, pre-mRNA splicing might have evolved to retain maximum functionality in terms of organ preference and multiplicity.

지진으로 인한 건물 손상 예측 모델의 효율성 분석

채송화,임유진,Chae Song Hwa,Yujin Lim 한국정보처리학회 2024 정보처리학회논문지. 컴퓨터 및 통신시스템 Vol.13 No.5

지진 발생은 정확히 예측하기 어렵고, 이러한 무작위성을 갖는 사건에 대비하여 모든 건물에 내진 설계를 도입하는 것은 현실적으로 어려운 과제이다. 건물의 특징 분석을 통한 건물 손상 예측을 기반으로 건물의 취약점을 보완한다면, 내진 설계를 도입하지 않은 건물에서도 피해를 최소화할 수 있으므로 건물 손상 예측 모델의 효율성을 분석하는 연구가 필요하다. 본 논문에서는 2015년 네팔 대지진으로 인해 손상된 건물 데이터를 활용하여 Random Forest, Extreme Gradient Boosting, LightGBM, CatBoost 기계학습 분류 알고리즘을 사용하여 지진 피해 예측 모델의 정확도를 비교하였다. Predicting earthquake occurrences accurately is challenging, and preparing all buildings with seismic design for such random events is a difficult task. Analyzing building features to predict potential damage and reinforcing vulnerabilities based on this analysis can minimize damages even in buildings without seismic design. Therefore, research analyzing the efficiency of building damage prediction models is essential. In this paper, we compare the accuracy of earthquake damage prediction models using machine learning classification algorithms, including Random Forest, Extreme Gradient Boosting, LightGBM, and CatBoost, utilizing data from buildings damaged during the 2015 Nepal earthquake.
