본 실험에서는 황색종 KF-118을 사용하여 적심 후 발생하는 액아의 생장을 약제처리법을 이용하여 억제하였다. 약제로는 침투성 액아억제제, 접촉성 액아억제제, 국부성 액아억제제 등 세 종류의 약제를 활용하였다. 약제를 처리한 후 액아의 길이, 생장률, 생중량, 건중량 등을 측정하여 액아억제제의 효과를 측정하였다. A, B, C, D, E 총 5가지의 액아억제제를 처리하였으며 무처리구를 포함한 총 6개의 처리구로 나누어 시험하였고, 각 처리구는 적심 직후, 적심 후 액아가 2 cm 이하로 자랐을 때와 4 cm 이하로 자랐을 때로 분류하여 5주씩 3반복으로 처리구당 총 15주를 시험하였다. 실험 결과 무처리구와 처리구는 액아생장에 있어 유의성 있는 차이를 보였으며 처리효과는 적심 직후에 약제를 처리했을 때 가장 높았으며, 다음으로 적심 후 액아가 2 cm 이하로 자랐을 때, 4 cm 이하로 자랐을 때의 차례로 나타났다. 또한 적심 직후 약제를 처리한 경우 A약제를 제외한 모든 액아억제제가 억제율 90 %를 넘는 우수한 결과를 보였다. Suckers were controled by suckercide treatment using a flue-cured tobacco cultivar, KF-118. Three types of suckercides, systemic suckercide, contact suckercide and local suckercide, were used. Length, growth rate, fresh weight and dry weight of sucker were measured after suckercide treatment. Five kinds of suckercides (A, B, C, D, E) were treated directly after topping, when sucker length shorter than 2 cm after topping, and when sucker length shorter than 4 cm after topping. Five plants were treated and three times repeated. The sucker growth rates of treated plant were significantly lower than those of untreated plant. The smaller the sucker size, the higher the treatment effect. All suckercides, except for suckercide A, showed more than 90 % sucker control rate when they were treated directly after topping.

<P>Although there has been suggestive evidence of the association between TRAP and ADs, findings remained inconsistent possibly due to limited population. We investigated the association between TRAP and ADs in a large population of children with rich spatial coverage and expanded age span in Seoul, Korea. TRAP exposures were estimated by categorized proximity to the nearest major road (≤150, 150–300, 300–500, and >500 m) and density of major roads within 300 meters from children's residences. We estimated the association between two TRAP exposures and three ADs using generalized mixed model after adjusting for individual characteristics. We also investigated whether the association varied by household and regional socioeconomic status. We found associations of atopic eczema with road density [OR = 1.08; 95% CI = 1.01–1.15] and road proximity [1.15, 1.01–1.32; 1.17, 1.03–1.34; and 1.16, 1.01–1.34 for ≤150, 150–300, and 300–500 m, resp., compared to >500 m]. There was no association with asthma and allergic rhinitis. Effect estimates were generally the highest in the low socioeconomic region. Children living in areas surrounded by large and busy roads were likely to be at greater risks for atopic eczema, with increased vulnerability when living in deprived areas.</P>

일본어 화자 대상 중급 한국어 한자어 교육을 위한 한국어와 일본어의 동형 한자어 대조

이현주(Yi, Hyeon-ju),이선웅(Yi, Seon-ung) 우리말글학회 2013 우리말 글 Vol.59 No.-

본 연구는 일본어 화자를 대상으로 하는 중급 한국어 한자어 교육을 위한 기초 자료로서 한국어와 일본어의 동형 한자어를 대조하였다. 3절에서는 한일 동형 한자어의 형태적 차이를 파생어와 합성어로 구분하여 대조하였다. 파생어와 합성어에는 한국어에서만 사용되는 것, 일본어에서만 사용되는 것, 유사하지만 다른 것이 있었다. 특히 형용사 파생 접미사의 경우 한국어는 일본어와 달리 어휘에 따라 다양한 결합을 보이는 것을 보였다. 4절에서는 한일 동형 한자어의 통사적 차이를 품사 체계, 연어, 격조사 사용, 수식형, 피동, 기타로 구분하여 대조하였다. 동형 한자어임에도 품사가 달라 문장 안에서 달리 기능하기도 하고, 서술성 명사에서 파생된 동사는 그것이 취하는 논항의 격조사가 상이하기도 하다. 일본어에서 피동은 제한된 특정 문법 형식으로 나타나는 반면 한국어에서는 서술성 한자어에 피동을 의미하는 다양한 동사와 결합함을 밝혔다. In this paper, we contrast formally-identical Sino-Korean words and Sino-Japanese words of intermediate level for Japanese Korean Learners. In section 3, we contrast formally-identical Sino-Korean words and Sino-Japanese words in derivative words and compound words respectively. There are Sino-words only in Korean and Sino-words only in Japanese and Sino-words which are similar to each other but different from each other. Especially, Sino-Korean words are more various than Sino-Japanese words in derivative adjectives. In section 4, we contrast formally-identical Sino-Korean words and Sino-Japanese words syntactically in categories that are word class system, collocations, use of case markers, modifiers, passives and others. There is a case that formally-identical Sino-Korean words and Sino-Japanese words function differently from each other according to the difference of word class and there is a case that Korean and Japanese derivatives of predicative nouns have different case markers from each other as well. Futhermore Korean passive is realized by various passive verbs or suffixes" being combined with Sino-Korean predicative nouns while Japanese passive is realized by a restricted specific grammatical form in Sino-Japanese words.

보육교사의 총근무시간과 스트레스 반응에 따른 휴게시간의 매개효과

정선이(Seon Yi Jeong),차승은(Seung Eun Cha),이주미(Ju Mi Yi) 한국복지상담교육학회 2023 복지상담교육연구 Vol.12 No.1

본 연구는 보육교사가 경험하는 총근무시간과 다양한 스트레스 관계에서 휴게시간이 필요하다는 문제의식을 바탕으로 휴게시간의 중요성을 알아보고자 하였다. 따라서 보육교사의 총근무시간이 스트레스의 하위요인인 감정․인지․행동․신체적 반응에 미치는 영향을 확인하고, 매개변수인 휴게시간이 영향력을 나타내는지 살펴보았다. 경기도에 소재한 어린이집(예: 국공립, 법인, 민간, 가정)에 근무하는 362명의 보육교사를 대상으로 설문조사를 실시하고, SPSS 28.0과 JAMOVI 통계프로그램을 사용하여 기술통계와 위계적 회귀분석을 하였다. 연구결과, 보육교사의 총근무시간은 정서․인지․행동․신체적 반응 모두에 정적상관을 보여 근로시간이 길수록 모든 영역에서 스트레스가 증가함을 나타냈다. 휴게시간을 투입하였을 때 총근무시간이 행동․신체적 반응 사이의 연관성은 유의미하지 않았지만, 정서․인지적 반응에서 스트레스가 감소하는 것으로 나타났다. 따라서 휴게시간이 스트레스에 직접적으로 영향을 미치는 것으로 나타나 휴게시간이 스트레스의 모든 하위요인을 완화하는 데 도움이 될 수 있음을 시사한다. 본 연구결과는 보육현장에서 휴게시간의 필요성과 보육시설에 대한 근무환경이 재조명되기를 바라며 이를 위한 제도적 발전 방향에 기초자료 및 아이디어를 제공했다는 데 의의가 있다. The aim of this study was to investigate the relationship between working hours, break time, and stress response among childcare teachers. We hypothesized that break time could help alleviate the negative impact of long working hours on stress levels among childcare teachers. We measured stress response across four sub-dimensions: emotional, cognitive, behavioral, and physical. We collected data from 362 childcare teachers working in various daycare centers (e.g., national and corporate, private and home day care centers) in the Gyeonggi-do area. We analyzed the data using descriptive statistics and a stepwise regression model using SPSS 28 and JAMOVI. Our results show that working hours were positively associated with all four dimensions of stress response, indicating that longer working hours can lead to increased stress in all domains. However, when we included break time in the analysis, the association between working hours and behavioral/physical stress response was no longer significant. For emotional and cognitive stress response, the working hour coefficient remained significant but decreased in magnitude. Additionally, we found a direct negative effect of break time on stress, suggesting that taking breaks can help alleviate stress across all four dimensions. The results of this study are meaningful in that they provided basic data and ideas on the direction of institutional development for this, hoping that the need for rest time and the working environment for childcare facilities will be re-examined.

Prediction of supercavitation shapes for a wide range of Froude numbers

Yi Jong-Ju,Kim Min-Jae,Kim Seon-Hong,백부근,김경천 대한조선학회 2022 International Journal of Naval Architecture and Oc Vol.14 No.1

In this study, we developed an inviscid model to predict the shape of supercavitation in a wide range of Froude numbers (Fr) based on the potential theory suggested by Logvinovich (1973). Visualization experiments were carried out in a cavitation tunnel, and shapes of supercavitation were obtained for 15 < Fr < 30. Existing data on supercavity shapes at high Froude number (100 < Fr < 400) were used to verify the developed model. As a result, the cavity shapes at high Froude number were predicted with high accuracy because the cavity rise is weak due to relatively low buoyancy. In the case of low Froude number (15 < Fr < 30), the cavity shapes were predicted within 5e10% accuracy from the cavitator to 2/3 of the total cavity length due to the strong effect of buoyancy.
