유아교육기관 글자 그림책 활용실태와 유아교사 인식

박지해,김민진 이화여자대학교 교과교육연구소 2017 교과교육학연구 Vol.21 No.6

This study focuses on the utilization of alphabet books and the perceptions of teachers in early childhood institutions. This study was conducted on 250 teachers who were working at early childhood institutions. Firstly, this study investigated the utilization of alphabet books in early childhood education institutes. Specifically, the majority of institutions of early childhood education do not possess diverse alphabet books and less than 50% teachers do not implement these materials. The results also showed that teachers use alphabet books to fulfill the children’s interests in alphabets. Secondly, this study investigated the teachers’s perception on alphabet books. Specifically The majority of teachers think that reading alphabet books is a necessary part of early childhood education institutions and such readings positively affect children’s cognitive, language and emotional development. The majority of teachers have difficulties in alphabet book teaching due to the lack of books in their institutions, and they think early childhood institutions should have a variety of these alphabet books. 본 연구의 목적은 유아교육기관에서의 이루어지는 글자 그림책의 활용실태 및 교사 인식을 파악하는데 있다. 어린 이집과 유치원에 근무 중인 유아교사 250명을 대상으로 설문조사를 실시하였다. 먼저 그림책 읽기 실태 조사와 관련하여 글 자 그림책을 가지고 있지 않다는 응답이 가장 많았다. 글자 그림책 읽기 실시 여부의 경우 과반수에 조금 미치지 못하는 교 사가 실시해본 적이 없다고 응답하였다. 글자 그림책 읽기의 주된 목적으로는 글자에 대한 유아의 흥미 충족이라는 답변이, 집 단 크기로는 대집단 읽기라는 응답이 그리고 글자 그림책 ‘기차ㄱㄴㄷ’을 읽어준다는 응답이 가장 많았다. 다음으로 교사 인 식과 관련해서는 대부분의 교사들이 글자 그림책 읽기 활동이 필요하다고 응답하였다. 글자 그림책 읽기가 유아의 인지, 언 어, 정서 발달에 모두 도움이 된다고 응답하였다. 글자 그림책 선정 기준으로 유아 연령 및 발달 수준을 가장 많이 고려하 는 것으로 나타났다. 가장 큰 어려움으로 글자 그림책 보유 부족을 꼽았으며 다음으로 교사의 관심 부족과 활용방안에 대한 이해 부족을 꼽았으며 개선 방안 역시 글자 그림책의 비치를 가장 많은 교사들이 꼽았다. 본 연구 결과는 글자 그림책의 교 육적 가치 및 종류 그리고 활용방안에 대해 적극적인 교사교육이 필요함을 시사한다.

해동피를 80% EtOH 용액으로 추출하고, 추출물을 EtOAc, n-BuOH 및 H20로 분배, 추출하였다. 이 중 EtOAc 분획 을 silica gel 및 octadecyl silica gε1 column chromato -graphy로 정제하여 2종의 페놀산 화합물을 분리하였다. 이 화합물의 화학구조는 NMR, MS 및 IR 등의 스펙트럼 데이터를 해석하여, methyl 3-0-feruloylquinate(1)와 methyl 3,5-0-dicaffeoyl quinate(2)로 동정하였다. 이 화합물들은 해동피에서 처음으로 분리,동정하였다.

한국문학 읽기를 통한 여성결혼이민자의 자기긍정성 증진 가능성 연구

박지해,박종대 세계문학비교학회 2019 世界文學比較硏究 Vol.67 No.-

The purpose of this study is to shed light on the female marriage immigrants’ inner and outer conflicts which they experience in living in South Korea. Also, it proposes to read the Korean literature for them to promote the self positivity by living as the transnational existence. If we assume that their living spaces are in South Korea, they are given more than two cultural backgrounds regardless of their countries of origin. They could not no more assert the identify which is obtained from their countries of origin and cultures and live as the perfect Korean existence. They are enough diasporic in point of having the immigrant experiences and more than two cultural backgrounds. Therefore, it could be the perfect process of understanding their various distinct characteristics when all we try to figure out the way to have the self positivity for them as diasporic existence. It could be another alternative to establish their subjecthood in Korean society as well. 본 논문은 한국의 여성결혼이민자가 갖고 있는 존재적 특수성을 이해하고 그들이 이 땅에서 자기정체성 및 자기긍정성을 확보하고 살아가는 데 필요할 다양한 경험치들 중에 ‘한국문학 읽기’에 주목하였다. 자신이 살고 있는 땅의 사회문화적 맥락과 언어가 담긴 한국문학작품을 읽는 과정은 여성결혼이민자가 자신이 놓인 시공간을 다각적으로 사유하고 수용하게 하는 밑거름이 될 것이다. 물론 한국에 거주하는 여성결혼이민자로서 여타 세계문학 읽기 활동이 주는 이점도 배제할 수 없다. 다만 본고는 그들의 존재적 특수성에 직접 연관되는 한국문학 읽기가 한국에 살고 있는 자기 자신, 가족, 사회, 한국에 대한 사유를 구체화하여 여성결혼이민자로서의 자기긍정성을 확보하는 데 유용할 것이라고 보았다. 이러한 전제를 바탕으로 여성결혼이민자의 자기긍정성 확보에 유용할 한국문학을 선택, 제시하였다.

Keloids result from excessive production of fibrous tissue during an abnormal wound healing process. Keloids can occur after trauma, and trauma can range from laceration, piercing, bites, surgery, and burns, to other skin conditions such as acne or folliculitis. We present a case of 68-year-old man, which was characterized with a relatively firm, non-tender, mild pigmented mass in his right earlobe. We performed a local excision, together with microscopic analysis. The mass was eventually diagnosed as a keloid scar in the right earlobe. Postoperative adjuvant pressure therapy using magnets was adopted and the postoperative follow-up was maintained without any recurrence. Auricular keloids should be considered in the differential diagnosis regardless of the cause or the age of patient.

Background: The purpose of this study was to explore the relationship between the local extinction index and total medical serviceutilization. Methods: A fixed effects model in panel analysis was performed for the 228 administrative districts in Korea. The statistical yearbookon the usage of medical services by region and Korean Statistical Information Service data were used from 2010 to 2019 for analysis. Medical service utilization was represented by the number of visits day, the number of inpatient days, and medical charges. Controlvariables were selected by using an Anderson model. The local extinction index was calculated using resident registration populationdata. Results: Descriptive statistics showed that the number of areas at risk of extinction increased from 61 to 95 for the study years. Inaddition, the number of visits, the number of inpatient days, and medical charges all increased during the study years. Aftercontrolling for variables affecting medical service utilization and doing a panel fixed effects model, the result suggested that aone-step increase in the local extinction index was significantly associated with a 12.29% decrease in medical charges of inpatients,a 7.33% decrease in medical charge of outpatient, a 5.21% decrease in the number of inpatient day, and a 5.54% decrease in thenumber of visits day. Conclusion: This study showed that the higher the region’s extinction risks, the higher the region’s total medical service utilization. The results of this study suggested that there was a disparity in medical service utilization between areas at risk of extinction andareas not at risk of extinction, so measures should be taken to address this disparity.

Three diarylheptanoids, bisdemethoxycurcumin (1),curcumin (2), and demethoxycurcumin (3), two diarylpentanoids,3,3'-bis(7,7'-hydroxy-6,6'-methoxyphenyl)-penta-(3E,2'E)-3,2'-dien-1-one (4) and 3,3'-bis(7,7'-hydroxy-6-methoxyphenyl)-penta-(3E,2'E)-3,2'-dien-1-one (5), and a bisabolane sesquiterpene,xanthorrhizol (6), were isolated from the rhizome of Curcumaxanthorrhiza through repeated column chromatography. Silica gel(SiO2), octadecyl silica gel (ODS), and Sephadex LH-20 resinswere used. Compounds were identified by spectroscopic methods,including nuclear magnetic resonance, mass spectrometry, andinfrared spectroscopy. Compounds 1 (IC50: 8.21 μM), 2 (IC50:10.01 μM), 3 (IC50: 4.86 μM), and 4 (IC50: 2.20 μM) inhibitednitric oxide production in LPS-stimulated RAW264.7 macrophagecells. High performance liquid chromatography was used todetermine the content of curcuminoids and xanthorrhizol in C. xanthorrhiza extract to be 0.46±0.08% (1), 10.69±0.18% (2),2.35±0.06% (3), 0.18±0.05% (4), 0.03±0.01% (5), and 27.47±2.42% (6).

SWOT-AHP 분석을 통한 지속가능 수산 발전 전략에 관한 연구 : 기술혁신의 관점을 포함하여

박지해,천동필 한국수산해양교육학회 2020 水産海洋敎育硏究 Vol.32 No.1

Domestic fisheries industry is facing a crisis such as resource scarcity and declining production that could lead to continued marine environmental pollution, ecological change in fisheries. Since Korean fisheries industry has a high value as a traditional industry directly linked to food security, it has emerged that it needs to turn its paradigm into a sustainable fisheries industry that can secure the recovery and availability of fisheries resources and further protect the marine environment. It is therefore considered necessary to address securing continuous growth, creating added value by setting the plan for sustainable development of the industry, by addressing the technological point of view. This study conducted SWOT-AHP analysis, selecting the strategic element of fishery source development based on the survey focusing on experts related to fishery business to calculate the relative importance of each element. As a result of analysis, the depletion of fishery resources and the continuous domestic demand showed high importance while emergence of new technology business, promotion of resource management policy, technology convergence and high-tech industrialization are selected as top major elements. This is believed that we should recognize the risk faced by our fisheries industry, and from the technical point of view, there is a need to seek the strategy including effective R&D establishment that can overcome this. This study is meaningful in that it is the first study that suggested the necessity of technology innovation by applying SWOT-AHP for the sustainable development of fishery industry, our traditional industry.
