This study aimed to investigate how teacher’s attitude toward violence affect students who experienced bullying victim in their role in making peer-to-peer violence deepen, and how students who experienced the bullying victim react to show aggression, and the aggression is blocked by teacher’s attitude toward violence, resulting in decrease of doing the bystander’s negative behavior. By conducing this study, this study ultimately aimed to ensure that the teacher’s attitude toward violence is very important in preventing peer bullying in the classroom. To achieve this aims, this study conducted a survey of 820 fourth, fifth and sixth graders in 40 classes at 10 elementary schools and limited only 365 of the respondents who reported experiencing peer bullying victim. This study utilized the structural equation modeling method to analyze the data. The results were as follows. First, it showed that the lower the bystander’s negative behavior in victims who experienced peer bullying, and the lower the responsive aggression reacted from the peer bullying, when the teacher shows an unacceptable attitude toward violence. Teacher’s attitude toward violence also appears to affect peer bystander’s negative behavior by mediating peer bullying victim’s reactive aggression, indicating that the teacher’s attitude toward classroom violence may reduce the aggression of students from the experience of victimization, and consequently prevent the classroom from becoming more leprosy by reducing peer bullying. 본 연구는 또래괴롭힘 피해 경험이 있는 학생들이 또래괴롭힘이 심화되도록 하는 주변인 역할 행동을 하는데 있어 교사의 폭력에 대한 태도가 어떤 영향을 미치는지와, 또래괴롭힘 피해학생의 반응적 공격성이 교사의 폭력 허용도의 영향을 받아 결과적으로 또래괴롭힘 방관 및 동조행동에 영향을 미치는 지 검증하고자 하였다. 이를 통해 또래괴롭힘 현상이 교실 내에서 심화되는 것을 예방할 수 있는 교사의 역할의 중요성을 검증하고자 하였다. 이를 위해 본 연구는 10개 초등학교 40개 반의 4, 5, 6학년 학생 820명을 대상으로 설문을 실시하고 설문응답자 중 또래괴롭힘 피해 경험이 있다고 보고한 학생들 365명의 설문자료만을 분석에 사용하였다. 이 자료를 구조방정식모형 방법으로 분석한 결과, 교사의 폭력 허용도가 낮을수록 또래괴롭힘 피해학생의 동조행동과 방관행동이 감소하는 결과를 보였으며, 교사가 폭력에 대해 허용치 않는 태도를 보일 때 또래괴롭힘 피해학생들의 반응적 공격성도 낮아지는 것으로 나타났다. 또한 교사의 폭력허용도는 학생의 반응적 공격성을 매개하여 또래괴롭힘 가해 동조행동과 방관행동에 영향을 미치는 것으로 나타나 교실 내 폭력에 대해 허용하지 않는 담임교사의 태도가 또래괴롭힘 피해 경험 학생들의 공격성을 낮추고, 결과적으로 또래괴롭힘 방관 및 동조행동을 낮춤으로써, 교실 내 또래괴롭힘 현상이 심화되는 것을 차단할 수 있음을 시사하였다.

임선아,이순아 한국아동교육학회 2022 아동교육 Vol.31 No.3

Recently, the use of smartphone is increasing and expanding to the younger age group in the non-face-to face era caused by COVID-19. Thus, this study examined the effect of excessive use of smartphone on elementary school students' academic enthusiasm. Specifically, this study investigated the effects of smartphone dependence on elementary school students' academic enthusiasm, mediated by study time, emotional problems (i.e., attention and withdrawal), and social relationships with peers and teachers longitudinally. To this end, this study analyzed the 2,134 data from the 1st (2018 data) to the 3rd (2020 data) survey data of the 4 elementary schools among from data of the Korean Children and Youth Panel Survey 2018 (KCYPS 2018) using structural equation modeling. The results are as follows. First, it was found that the dependence on smartphone in elementary school students had a direct negative effect on academic enthusiasm. Second, smartphone dependence was found to have a direct effect on study time, emotional problems, and social relationships. Specifically, it was found that smartphone dependence had a statistically positive effect on emotional problems such as distraction and withdrawal, but had a negative effect on study time, peer relationship, and relationship with teachers. Third, smartphone dependence was found to affect academic enthusiasm by mediating study time, emotional problems (distraction and withdrawal), and relationship with teachers. This study suggests the need for careful observation and guidance from elementary education to prevent a decrease in academic enthusiasm due to the dysfunction of smartphone dependence. 본 연구는 코로나19로 인한 언택트 시대에 스마트폰의 사용이 더욱 증가하고 저연령층으로 크게 확대되고 있는 시점에서, 스마트폰의 과도한 사용이 초등학생의 학업열의에 미치는 영향을 살펴보았다. 구체적으로 본 연구는 초등학생의 스마트폰 의존이 정서문제와 사회관계, 학습시간, 학업열의에 미치는 영향과 스마트폰 의존과 학업열의의 관계에서 주의력과 위축의 정서문제, 교우관계와 교사애착의 사회적 관계 및 학습 시간의 매개효과를 종단적으로 살펴보고자 하였다. 이를 위해 본 연구는 한국아동·청소년패널조사(Korean Children and Youth Panel Survey 2018: 이하 KCYPS 2018) 자료 중, 초등 4학년 패널 1차(2018년 자료)부터 3차(2020년 자료) 조사에 응답한 2,134 자료를 구조방정식모형(SEM)을 사용하여 분석하였다. 그 결과 첫째, 초등학생 고학년의 스마트폰 의존은 학업열의에 직접적인 부적 영향을 미치는 것으로 나타났다. 둘째, 스마트폰 의존은 학습시간, 정서문제, 사회관계에 직접적인 영향을 미치는 것으로 나타났다. 구체적으로, 스마트폰 의존은 산만과 위축 등의 정서문제에는 유의미한 정적인 영향을, 학습시간과 또래관계 및 교사관계에는 부적인 영향을 미치는 것으로 나타났다. 셋째, 스마트폰 의존이 학습시간, 정서문제(산만과 위축), 사회관계 중 교사와의 애착을 매개하여 학업열의에 영향을 미치는 것으로 나타났다. 본 연구는 스마트폰 의존의 역기능으로 학업열의가 감소하는 것을 예방하기 위하여 초등교육에서부터 세심한 관찰과 지도의 필요성이 있음을 시사하고 있다.

Activation of Macrophages by Exopolysaccharide Produced by MK1 Bacterial Strain Isolated from Neungee Mushroom, Sarcodon aspratus

임선아,이종길,이영남,Wenxia Wang 대한면역학회 2010 Immune Network Vol.10 No.6

Background: The MK1 strain, a novel bacterial isolate from soft-rotten tissue of the Neungee mushroom, produces copious amounts of exopolysaccharide (EPS) in a dextrose minimal medium. This study examined the molecular characteristics and immunomodulatory activity of MK1 EPS. Methods: The EPS in the culture supernatant was purified by cold ethanol precipitation, and characterized by SDS- PAGE/silver staining and Bio-HPLC. The immunomodulatory activities of the EPS were examined using the mouse monocytic cell line, RAW 264.7 cells. Results: The molecular weights of the purified EPS were rather heterogeneous, ranging from 10.6 to 55 kDa. The EPS was composed of glucose, rhamnose, mannose, galactose, and glucosamine at an approximate molar ratio of 1.00:0.8:0.71:0.29:0.21. EPS activated the RAW cells to produce cytokines, such as TNF-α and IL-1β, and nitric oxide (NO). EPS also induced the expression of co-stimulatory molecules, such as B7-1, B7-2 and ICAM-1, and increased the phagocytic activity. The macrophage-activating activity of EPS was not due to endotoxin contamination because the treatment of EPS with polymyin B did not reduce the macrophage-activating activity. Conclusion: The EPS produced from the MK1 strain exerts macrophage-activating activity.

Previous studies have shown that Aloe QDM complex, which is consisted of chromium (Cr), aloesin (ALS) and processed Aloe vera gel (PAG), exert antidiabetic activity in a high fat diet-induced mouse model of type 2 diabetes. In this study we examined the mechanism of the antidiabetic activity of the Aloe QDM complex. Rat myoblast cell line L6 cells were cultured in the presence of Cr, ALS, and PAG alone and in combinations, and then the capability of the cells to uptake glucose was examined using radiolabeled glucose. All of the 3 agents, Cr, ALS and PAG, exerted glucose uptake-enhancing activity in L6 cells. The most potent capability to uptake glucose was observed when L6 cells were cultured with the Aloe QDM complex. The activity of the Aloe QDM complex to enhance glucose uptake was prominent in conditions where existing insulin concentrations are low. We also examined the effects of the Aloe QDM complex on the plasma membrane expression of GLUT4 in L6 cells. The Aloe QDM complex increased the content of GLUT4 in the plasma membrane, while decreasing the content of GLUT4 in the light microsome. Taken together, these results show that the antidiabetic activity of the Aloe QDM complex is at least in part due to the stimulation of glucose uptake into the muscle cells, and this activity of the Aloe QDM complex is mediated through the enhancement of the translocation of GLUT4 into the plasma membrane.

알로에 다당체 Acemannan의 면역증강 효능

임선아,이종길,박찬수 한국생약학회 2016 생약학회지 Vol.47 No.2

Aloe vera L.(Aloe barbadensis Miller) has been used for many centuries for various medical, cosmetic and neutraceutical purposes. The gel of A. vera was reported to exert numerous biological activities including wound healing, immunomodulatory, anti-cancer, anti-inflammatory, anti-bacterial, anti-viral, anti-diabetic, and anti-psoriasis activities. Acemannan, found predominantly in the inner leaf gel of A. vera, has been identified as the main active ingredient exerting diverse biological activities. In this review, we summarized the recent findings on the immunomodulatory activities of acemannan. Studies that used purified acemannan demonstrate that acemannan exerts immune-stimulating, anti-cancer, anti-viral, and hematopoiesis-increasing activities. In addition, it is being clear that most of these activities of acemannan are mediated primarily by activating professional antigen presenting cells such as macrophages and dendritic cells.
