The objective of this study was to identify the effect of zebularine soaking on the early growth stage of barley (Hordeum vulgare L.). Hence, root elongation was measured daily according to the different concentrations of zebularine (1.0, 2.5, 5.0, and 10.0 μM) for 4 days. On the first day, root length at 2.5 and 5.0 μM was significantly longer than that in the non-treated control. On the second day, root length was not significantly different among all concentrations and controls. On the third day, root elongation was suppressed by the effect of zebularine, except at 2.5 μM. The treatment time of zebularine accounted for the largest proportion of the variation in root elongation. After transplanting, plant growth velocity was similar to that of the control; however, plants at 2.5 μM showed faster growth velocity than that of the other concentrations and the control. In the metaphase of mitosis, most chromosomes of cells under zebularine treatment were ordinary regardless of the concentration, while some cells with short chromosomes were investigated at around 2%. The short chromosome showed a centromere. In addition, it showed short and long arms based on the centromere. The lengths of the short and long arms were different for each short chromosome. It is necessary to study the effect of the short chromosome as a chromosomal function on plant growth and phenotype through investigation of meiosis and fertilization at the chromosome level.

본 연구의 목적은 주자의 경(敬)이 오로지 ‘학습 방법’인지, 오로지 ‘학습의 과정’인지, 아니면 ‘학습 방법’이자 ‘학습의 과정’인지를 검토하기 위한 것이다. 문맥에 따라 경은 교육적 관점에서 다음과 같이 구분된다. 첫째, ‘내어버린 마음을 구한다’, ‘마음을 한곳에 모아 나아가지 않는다’, ‘정돈하여 가지런히 하고 엄숙하고 정중하게 한다’, ‘항상 고요하게 하는 방법’, ‘그 마음을 수렴하여 하나의 사물도 용납하지 않는다’와 같은 맥락에서 경(敬)은 ‘학습 방법’에 속한다. 둘째, 문맥에 따라 경(敬)은 삼가는 ‘학습 방법’을 구성 요소로 하는 ‘학습의 과정’에 해당한다. 학습자는 소학 ‘과정’에서 삼가는 ‘학습 방법’으로 덕행을 모방할 줄 아는 대로 몸소 익히고, 대학 ‘과정’에서 늘 깨어 있는 ‘학습 방법’으로 마음의 성(性)을 아는 대로 행하면서 학문을 이룬다. 따라서 문맥에 따라 주자의 경(敬)은 ‘학습 방법’에 해당하는 경우가 있고 ‘학습 방법’ 요소로 구성된 ‘학습의 과정’에 해당하는 경우가 있으므로, 독자는 맥락에 부합하게 경을 분석적으로 파악하면서 온전히 적용해야 한다.
Chat GPT를 활용한 단계별 지식교육 엘긴(Elgin)을 중심으로

본 연구의 목적은 엘긴에 토대를 두고 비판적 대화를 통해 거짓을 식별하지 못하는 단계에서거짓과 적당한 거짓을 변별하고 선별한 적당한 거짓을 탐구해 진리를 추구하는 단계로 나아가는지식교육을 고찰하기 위한 것이다. 본 연구는 교육내용에 대해 비판적으로 토론할 때 ChatGPT를활용해 거짓과 적당한 거짓을 식별하면서 진리를 탐구하는 교육철학을 엘긴의 사려깊은 판단, 충분한 사실과 같은 문헌을 중심으로 살펴보는 연구 방법으로 이루어질 것이다. 엘긴의 교육철학에 기반한 지식교육은 참과 거짓을 식별하지 못하는 교육 대상에게 질문해서 ChatGPT가 생성한답변이 참인지 거짓인지를 검토하는 기능을 한다. 다음 단계에서는 비판적 토론을 통해 적당한거짓을 탐구하다 오류를 발견할 때마다 경험으로 정정하면서 진리를 추구하는 기능을 한다. 그러나진리를 추구하는 단계별 지식교육은 수업을 집중해서 듣지 않은 학습자가 거짓을 진리로 믿을수 있고, 식별 능력을 검사하기 위해 타당도·신뢰도·객관도를 갖춘 교육 평가를 시행하는 일이간단하지 않으며, 비판적 대화로도 식별 능력을 지니지 못하는 경우가 있다는 점에서 한계가 있다. The purpose of this study is to explore knowledge education that progresses from a stage where falsehoods cannot be discerned through critical dialogue, based on Elgin, to a stage where felicitous falsehoods are discerned and explored to pursue truth. This study will examine the educational philosophy of exploring truth by discerning falsehoods and felicitous falsehoods using ChatGPT when critically discussing educational content, based on literature such as Elgin’s “Considered judgment” and “True enough”. Knowledge education based on Elgin’s educational philosophy serves to question the educational target who cannot discern truth and falsehoods, and review whether the answer generated by ChatGPT is true or false. In the next stage, it serves to pursue truth by correcting errors whenever they are discovered while exploring felicitous falsehoods through critical discussion. However, step-by-step knowledge education pursuing truth has limitations in that learners who did not concentrate on the class may believe falsehoods as truth, it is not easy to conduct educational evaluations with validity, reliability, and objectivity to test discerning ability, and there are cases where discerning ability cannot be acquired even through critical dialogue.

Acquired multiple cavernous hemangiomatosis appear on the skin and internaI organs, including in particular the skeleton, the brain and the liver in childhood or in adult life in the 4th and 5th decades. It is extremely rare for cutaneous hemangiomas associated with internal lesions to arise de novo in adults. The lesions persist indefinitely and symptom-free survival to old age is possible, despite the presence of hemangiomatosis in liver, heart or kidney. A 53 year-old male patient had multiple, non-tender, bluish to violet colored. pea to walnut sized, cutaneous, some pedunculated nodules on the entire body for 8 years. Histopathologically, there were non-capsulated vascuiar tumor consisting of large variable sized blood vessels in the dermis and some organizing thrombi. There was no evidence of malinant change.

The purpose of this study is to develop a methodology for constructing Korean natural language inference corpus. Korean natural language inference corpus is a resource for developing and evaluating natural language inference models. First, the cases of Korea and other countries are reviewed. Through this, we propose a corpus construction methodology. Second, in terms of the composition of the corpus, labels, format, and size are suggested. Lastly, this study suggests three-step process of building the corpus: collecting premise sentences, generating hypothesis sentences, and examining the semantic relations. This study can contribute to developing Korean natural language inference models.

Hypertrophic lichen planus is rare chronic variant of this disease, usually occurs on the lower extremities especially the shins, and associated with severe itching sensation. We report a case of localized hypertrophic lichen planus with bilateral hyperkeratotic polygonal violaceous papuloplaques on both upper eyelids and dorsa of hands and lace-like patches in oral mucosa. The patient had been treated with triamcinolone acetonide intralesional injection at two week intervals, two times and topical steroid after then the lesion had significantly improved.
