This study examined the effects of dietary processed pine needle tree powder (PPNP) on growth performance, visceral organ parameters, ileal digestibility, blood metabolites and ileal morphology of broiler chickens for 5-week after hatch. In total, 220 1-day-old male Ross 308 broiler chicks were randomly allocated to 30 pens (seven birds per pen), and each pen was assigned to one of five dietary treatments, a diet without PPNP (control) and diets with 0.5%, 1.0%, 1.5% and 2.0% PPNP. The body weight and feed intake were measured weekly. One bird from each pen was selected randomly and gently euthanized to collect the blood, visceral organs and digesta samples on 2, 3 and 5 week of age. Birds fed 2.0% PPNP showed decreased (P<0.05) overall body weight, average daily gain and average daily feed intake compared to those fed control, 0.5 and 1.0% PPNP. The small intestine length increased (P<0.05) as the level of PPNP in the diet increased. A deeper crypt depth was observed (P<0.05) when birds fed 2.0% PPNP compared to those fed the control diet at week 2. A higher V:C ratio was observed (P<0.05) in birds fed 1.0% PPNP than in those fed other treatments at week 3. Ileal protein digestibility improved (P<0.05) when birds fed 0.5% and 1.0% PPNP compared to that in those fed the control diet at week 3. The feed conversion ratio, ileal dry matter digestibility and blood urea nitrogen and cholesterol, and gizzard and ceca weights were not affected (P>0.05) by supplementation of any levels of PPNP. These results demonstrated that inclusion of PPNP in broiler diets could be a possible factor in improving overall growth performance suggesting early gut development when 1% PPNP is supplemented.

음운 분석과 어휘 분석을 통한 운문 텍스트의 언어적 속성 연구 -김소월의 「엄마야 누나야」와 「진달래꽃」을 대상으로-
정은주 ( Jung Eunjoo ) 우리어문학회 2021 우리어문연구 Vol.70 No.-
본고는 음운과 어휘 층위에서 운문 텍스트의 언어적 속성을 분석할 수 있는 방법론을 제안하고, 그것이 실제 텍스트 분석에서 어떻게 적용되는가를 실증적으로 제시하고자 하였다. 음운 층위 분석은 자음과 모음, 음절의 세 차원에서 이루어지며, 어휘 층위 분석은 품사와 어휘 등급의 두 차원에서 이루어지는데 이들은 모두 수치화되어 객관적인 비교가 가능하다. 이러한 분석 기제가 실제 텍스트 분석에 어떻게 적용되는지를 보이기 위해 김소월의 시 「엄마야 누나야」와 「진달래꽃」을 음운 층위, 어휘 층위에서 분석하고 그 결과에 통계적 해석을 적용하여 두 작품의 차이점을 규명하였다. 구체적으로, 음운 층위에서는 비음의 빈도가 높은 「엄마야 누나야」가 「진달래꽃」보다 높은 음악성을 띠며 어휘 층위에서는 명사와 조사의 빈도가 높은 「엄마야 누나야」가 운문성을 드러내는 한편 동사와 어미의 빈도가 높은 「진달래꽃」은 산문성을 드러냄을 밝혀내었다. 음운과 어휘 두 층위에서 도출해 낸 이러한 결과는 모두 「엄마야 누나야」가 「진달래꽃」보다 운문 텍스트 고유의 특성을 뚜렷이 드러냄을 시사한다. This study proposed the method that can analyze language attributes of verse at phonological and lexical levels and offered how the method applies to language attribute analysis empirically. Phonological strata analysis is conducted on three dimensions: consonant, vowel, and syllable whereas lexical strata analysis is implemented on two dimensions: part of speech and and vocabulary level. These analyses can be quantified and compared to each other objectively. To examine how these analytical mechanisms apply to language attribute analysis, this study investigated Kim So Wol’s poems 「Eomaya Nunaya/Dear mom and Dear sister」 and 「Jindallaekkot/Azalea」 in terms of phonological and lexical strata. Based on the analysis, this study validated differences between the two poems by applying statistical data interpretations. In specific, 「Eomaya Nunaya」 which has high frequencies of nasal sounds showed higher musicality than did 「Jindallaekkot」 in phonological strata. 「Eomaya Nunaya」 which has high frequencies of nouns and particles demonstrated verse traits whereas 「Jindallaekkot」 which has high frequencies of verbs and suffixes showed prose traits. The results drawn from analyzing the two poems at the phonological and lexical levels indicate that 「Eomaya Nunaya」 entails the original verse traits more apparently than does 「Jindallaekkot」.

학습몰입이 자기효능감과 교육만족도에 미치는 영향 : 항공관련학과 학습자 대상으로

The purpose of this study is to analyze the effect of learning immersion on self-efficacy and educational satisfaction and examine ways to improve educational satisfaction by increasing learning immersion and self-efficacy for students in the fields of aviation, as the importance of and the need for studying learning immersion have risen in the midst of changing learning environments due to the paradigm shift in education and the outbreak of the coronavirus disease (COVID-19). This study of 232 college students in aviation-related fields was analyzed with SPSS 21.0. The main finding of this study reveals that cognitive immersion and behavioral immersion in learning immersion have a meaningful effect on self-efficacy and self-regulating efficacy. This indicates that, as the learners developed their own study plans and other cognitive strategies and actively engaged in and performed learning activities to achieve their learning goals, their such efforts influenced self-regulation ability, leading them to immerse themselves in learning. The result illustrates that learning design with learner-centered approaches and the development and use of concrete educational content based on these approaches are important for enabling college students in aviation-related fields to immerse themselves in learning in online and offline environments and increase self-efficacy and educational satisfaction.

본 연구는 영유아관련 국내등재학술지에 게재된 영유아 권리의 연구동향을 분석하여 향후 영유아 권리연구의 과제와 방향설정을 위한 기초자료로 활용하는데 그 목적이 있다. 연구자료는 2010년부터 2016년까지 국내등재학술지 32종에 게재된 영유 아권리관련 국내연구 74편을 연구년도, 연구내용, 연구방법을 기준으로 분석하였다. 연구년도에 따른 분석결과 2010년 5편에서 2016년 22편으로 매년 꾸준히 증가하는 추세를 보였다. 연구대상으로는 영유아교사, 영유아, 부모 등의 순으로 연구가 많이 진행되었으며, 권리의 내용범주로는 권리의 개념연구, 변인연구, 권리증진활동 등의 순으로 많은 연구가 진행되었다. 또한 권리연구는 양적연구가 대부분을 차지하였고, 질적연구, 문헌연구, 혼합연구도 꾸준히 증가하는 결과를 나타냈다. 이를 통해 현재 영유아와 관련된 권리연구는 꾸준히 증가하고 있으며, 그 중에서 영유아 권리의 의미탐색에 대한 양적연구가 활발히 이루어지고 있음을 알 수 있었다. 본 연구를 통해 영유아 권리의 의미와 가치를 재인식하고 영유아의 권리개념, 관련요인, 직접적인 실천연구에 대한 과제를 선정, 방향을 설정하여 다양한 영유아 권리 연구의 접근이 필요하다는 것을 알 수 있다. By intensively analyzing the latest research trends on young children’s rights in Korea, the present study aims to provide a basic research that could guide future research directions in the field. For the purposes, it collects 74 original studies in the area that have been published in 32 peer reviewed Korean journals during the sample period of 2010-2016, and then analyzes and classifies them in terms of the time the studies was published, research subjects, research topics, and methodologies. As for the study time, the number of the studies on young children’s rights has increased steadily from 5 in 2010 to 22 in 2016. The research subjects has been mainly focused on teachers, which is followed by young children and parents in order of the number of the published studies. In the analysis of contents of the rights, many studies have been conducted in order of studies on the concepts of the rights, research on variables, and rights promotion activities. Quantitative researches are the dominant methodology utilized in the studies, and qualitative research, literature reviews, and mixed studies have also increased steadily. These findings show that studies on young children’s rights have been steadily increasing recently, and reveal that it is the quantitative research on the conceptual explorations on the rights which is the most actively studied area in the studies. Finally, the present study suggests that it be necessary and urgent that we should incorporate various approaches and research topics including the concepts, related factors, and practical promotion program in the future studies on the young children’s rights.
