본 연구는 예비유아교사의 학업적 자기효능감과 그릿이 행복감에 어떠한 영향력을 미치는지 확인하는 데 목적이 있다. 이를 위해 부산광역시, 울산광역시, 경상남도 내에 소재하고 있는 대학교의 유아교육과에 재학 중인 예비유아교사 300명을 임의표집하여 연구대상으로 선정하였다. 예비유아교사의 학업적 자기효능감을 측정하기 위해 김아영, 박인영(2001)이 개발하고 타당화한 후 김병만, 김정주, 윤정진(2017)이 수정하여 사용한 학업적 자기효능감 검사도구를 사용하였다. 고, 그릿을 측정하기 위해 Duckworth, Peterson, Matthews와 Kelly(2007)가 개발한 Original Grit Scale(Grit-O)를 이수란(2014)이 한국실정에 맞게 번안한 척도를 사용하였으며, 행복감을 측정하기 위해 Seligman(2011)의 웰빙에 대한 PERMA 이론을 토대로 Butler와 Kern(2014)이 개발하여 김미진(2015)이 번안한 다차원적행복척도(Multidimensional Measure of Flourishing: MMF)를 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감에 대한 인식에 대한 결과로 모든 변인에서 보통 이상의 긍정적인 인식 정도가 나타났다. 둘째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감 간의 상관관계에는 유의미한 정적 상관관계가 있음을 알 수 있다. 셋째, 예비유아교사의 학업적 자기효능감은 예비유아교사의 행복감에 영향을 미치는 변인으로 나타났으나, 그릿은 예비유아교사의 행복감에 영향을 미치지 않는 변인으로 나타났다. The purpose of this study is to investigate the influence of pre-service early childhood teachers academic self-efficacy and grit on happiness. For this purpose, 300 Pre-service early childhood teachers in preschool education at universities located in Busan, Ulsan and Gyeongsangnam province were randomly sampled and selected. In order to measure the pre-service early childhood teachers academic self-efficacy, I used the academic self-efficacy test tool modified by Kim Byung-man, Kim Jung-ju and Youn Jung-jin (2017) after the development and validation of Kim Ae-Young and Park In-Young (2001). The original Grit Scale (Grit-O) developed by Duckworth, Peterson, Matthews and Kelly (2007) was used to measure grit. And to measure happiness, we used the multidimensional happiness scale developed by Butler and Kern (2014) and developed by Kim Mi-jin (2015) based on the PERMA theory of wellness in Seligman (2011). The results of this study are as follows. First, as a result of pre-service early childhood teachers perception of academic self-efficacy, grit, and happiness, positive perceptions were more than usual in all variables. Second, there is a significant positive correlation between the pre-service teacher s academic self-efficacy, grit, and happiness. Third, the academic self-efficacy of pre-service early childhood teachers was a factor affecting the happiness of pre-service early childhood teachers. Specifically, it was found that task difficulty preference, self-regulated efficacy, and self-confidence affect the happiness of pre-service early childhood teachers among the sub-variables of happiness. However, the sub-variables of Grit did not affect the pre-service teachers happiness.

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

Hypoparathyroidism is usually the result of an inadvertent surgical removal of all the parathyroid glands, In some instances, not all the tissues are removed, but the remainder undergoes vascular supply compromise secondary to the fibrotic changes in the neck after surgery, Previously, the surgery for hyperthyroidism was the most frequent cause of acquired hypoparathyroidism. Idiopathic hypoparathyroidism is a relatively rare disease that is characterized by hypocalcemia and hyperphosphatemia due to a parathyroid hormone deficiency of an unknown cause, It usually develops at a young age, and shows various clinical symptoms and signs accompanied with hypocalcemia. In addition, it is rarely associated with polyglandular autoimmune syndrome during the follow-up. Hypocalcemia and idiopathic hypoparathyroidism associated with labor and lactation are rarely reported condition previously. We here describe a case of a woman in whom the symptomatic severe hypocalcemia appeared after her delivery. We reviewed all the previously reported cases and suggest a possible physiological explanation for the association between pregnancy, lactation, and the appearance of symptomatic hypocalcemia.

To investigate the effect and mechanism of caffeine on endurance exercise, two experiments were performed. First, to test caffeine effect on aerobic exercise, 200-300g Sprague-Dawley rats were used and three groups, control group, low caffeine injection group and high caffeine injection group, were divided. Blood smpling by heart puncture were done at rest, after 30 min treadmill exercise, and after maximal exercise. Blood glucose, free fatty acid concentration were detected and following results were obtained. Glucose concentration showed significant difference between groups(p=0.0305) and also significant changes were exhibited between time(p=0.0004). Free fatty acid concentration had no difference between groups. but had significance between times(p=0.00065). Exercise endurance performance time showed significant difference(p=0.02350 in high caffeine injection group compared to control group. In this experiments, endurance exercise capacity was increased by caffeine injection. Therefore, second experiment was performed to investigate the effect of caffeine on ion current induced inhibitory amino acid neurotransmitter. GABA and glycine. Single periaqueductal gray neuron was acutely dissociated and nystatin perforated patch clamp was performed under voltage clamping condition. Caffeine evoked outward current in PAG neuron dose dependent manner. 1mM of caffeine application had no response. but 3mM caffeine evoked about 32.5±8.539pA outward ion current and 10mM caffeine evoked about 215.46±19.4pA outward current. 10^-2mM GABA activated Cl￣current and recorded by inward current. Caffeine inhibited GABA activated Cl￣ current concentration dependent manner. 10^-2mM of caffeine had no effect on 1-^-2mM of GABA response. but 10^-1mM caffeine inhibited GABA activated Cl￣ current about 5.74±2.13%, 1mM caffeine inhibited about 17.25±2.70%, 10mM caffeine inhibited GABA response about 45.31±7.71%. 10^-1mM of glycine activated Cl￣ current and also recorded by inward current. Caffeine inhibited glycine activated Cl￣ current concentration dependent manner. 10^-2mM caffeine decreased glycine activated Cl￣ current about 4.61±1.650%, 10^-1mM caffeine decreased about 6.49±2.24%, 1mM caffeine decreased about 26.82±4.27%, and 10mM caffeine decreased glycine response about 94.47±1.39%. These results suggest that caffeine inhibite inhibitory amino acid, GABA and glycine, this response causes excitation of CNS and this seems to be the basic mechanism of increasing effect to aerobic exercise performance by caffeine.

The purpose of this study is to validate and apply the parental early childhood education policy evaluation scale by applying the Nu-ri Curriculum for 3-to-5-year-olds. In order to achieve the purpose of this study, 232 parents were selected as the research subjects. The research tool was modified and supplemented with the policy of ‘Nu-ri Curriculum for 3-to-5-year-olds’ policy developed by Kim Byung-man (2018) Respectively. The data collected in this study were descriptive statistics, construct validity, correlation analysis, reliability analysis, item discrimination, confirmatory factor analysis, and AMOS 8.0 program. The results of this study are as follows. First, the degree of evaluation of the parental early childhood education policy evaluation scale applying the ‘Nu-ri Curriculum for 3-to-5-year-olds’ policy was 2.84 ~ 3.66. The average of the public interest evaluation index of the colony was the highest, and the demographic average of the true women index was the lowest. Second, as a result of the reliability and validity test, it was proved through statistical significance that the parents' evaluation scale applying the policy of ‘Nu-ri Curriculum for 3-to-5-year-olds’ was valid and reliable evaluation scale for the early childhood education policy. This study suggests that the validity and application of the early childhood education policy evaluation scale suggests the possibility of active involvement of parents in the evaluation area of early childhood education policy.

Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans

Song, Mi-Young,Kim, Sang Hoon,Ryoo, Ga-Hee,Kim, Mi-Kyung,Cha, Hye-Na,Park, So-Young,Hwang, Hong Pil,Yu, Hee Chul,Bae, Eun Ju,Park, Byung-Hyun Nature Publishing Group UK 2019 Experimental and molecular medicine Vol.51 No.5

<▼1><P>Adipose tissue inflammation is a reproducible feature of obesity and obesity-linked insulin resistance. Although sirtuin 6 (Sirt6) deficiency has previously been implicated in diet-induced obesity and systemic insulin resistance, the adipocyte-specific role of Sirt6 in the regulation of adipose tissue inflammation and systemic metabolic dysfunction in mice fed normal chow and in humans remains elusive. Here, using <I>Adipoq-Cre</I>-mediated adipocyte-specific Sirt6 knockout (aS6KO) mice, we explored whether adipocyte Sirt6 inhibits adipose tissue inflammation and its underlying mechanism. aS6KO mice fed normal chow gained more body weight and fat mass than wild-type mice and exhibited glucose intolerance and systemic insulin resistance. Measurement of plasma and tissue cytokines and flow cytometric analysis of adipose stromal vascular cells indicated a decrease in alternatively activated M2 macrophages in the adipose tissue of aS6KO mice. Mechanistically, Sirt6 regulated the expression of the canonical type 2 cytokine IL-4 by adipocytes in a cell autonomous manner, which in turn affects M2 macrophage polarization. Consistent with animal experimental data, the degree of obesity and insulin resistance demonstrated by the body mass index, fasting blood glucose and HbA1c correlated negatively with the expression of Sirt6 in human visceral fat tissues. Collectively, these results suggest that adipocyte Sirt6 regulates body weight gain and insulin sensitivity independent of diet, and the increased IL-4 production by Sirt6 and resultant M2 polarization of adipose tissue macrophages may attenuate proinflammatory responses in adipose tissue.</P></▼1><▼2><P><B>Obesity and diabetes: A control protein in fat</B></P><P>A protein in adipose tissue (composed of fat cells) helps protect against inflammation and the development of resistance to insulin that develops in obesity and can lead to type 2 diabetes. Researchers in South Korea, led by Eun Ju Bae at Woosuk University, Wanju, and Byung-Hyun Park at Chonbuk National University, Jeonju, investigated the role of Sirt6 in mice and in human adipose tissue. Deleting the mouse gene that codes for Sirt6 in adipocytes promoted the impaired response to insulin and associated increase in blood glucose levels that are two key aspects of diabetes. Changes in biochemical signaling pathways controlling immune cells called macrophages were implicated in these effects and suggest an anti-inflammatory role for Sirt6. Analysis of human adipose tissue supported these findings. The research will help understand how obesity promotes type 2 diabetes.</P></▼2>

動作 分析法 硏究 : Choreometrics 分析法을 中心으로 Choreometrics

金末愛,安秉珠 慶熙大學校 1992 論文集 Vol.21 No.-

Dance was once considered an expression of individual feeling, but many studies have shown that dance is more related to cultural pattern. Foreign countries have recently more accessible, and interest in other cultures has therefore increased. Intra-cultural dance styles are also part of search for deeper understanding of dance as a cultural and universal experience, as well as the different elements in apparently foreign culture. The paper was studied Alan Lomax's Choreometrics, a dance-work rating system, as a methodology of understanding certain basic cultural aspects of dance. Its descriptive coding system includes study of the followings: (a) body parts habitually involved, (b) the body attitude, (c) nature of transition.
