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.

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

<▼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>

It appeared over all regions expect common life area that the pollutants level of soil heavy metals in Pusan and kyoung-Nam Province, was higher than the standard on in agriculture area. Especially, Atmosphere and waste area appeared much high and it necessitates monitoring these areas continually. Where we analyzed pollutants level of heavy metals in paddy soils in correspondence with Pusan, Ulsan, and Yangsan region, the order of Pb and Cd concentration were Yangsan 〉 Pusan 〉 Ulsan, the order of Cu and Zn were Yangsan 〉 Ulsan 〉 Pusan, the order of Hg and As were Ulsan 〉 Yangsan 〉 Pusan respectively. It appeared the whole concentration of heavy metals expect Hg and As were the highest ones in Yangsan. So, it was thought that special management should be needed. The analysis of correlation between heavy metals in soil showed that the correlation level between Cd and Pb, Cu and Pb and Zn, Hg and As was high in agricultural area and the correlation level between Zn and Pb, Cd and Hg, Cd and Cu was high but the one between Cd and As was low in atmosphere area. And the correlation between Pb and Cd, Hg and Zn, Hg and Cu was high but the one between Hg and Cu was low in waste area and the correlation level between As and Pb, As and Zn was slightly high but the one between Cd and Cu is low in water area.

The relative density seems to be important as a factor of controlling the physical properties in the case of cohesionless soil ground as sand. Therefore, the study is more important about the method for reappearing he same relative density when the specimen of shearing test is to be produce or the model test of ground is to made. In this study, the apparatus making use of the multiple sieving pluviation method-one of the reappearance of relative density-could be made. Using this apparatus, tests were practiced varying the factors such as the size of sieve mesh and the number of sieve, the amount of falling discharge, the falling height etc. about the standard sand in Jumunjin and Hadong sand. When laboratory test is perfomed by the cohesionless soil, it presents the method for reappearing of the relative density in field.

Software development environment is one of important features to extend the application area and to make rapid progress in any computing application fields. We studied and compared the programming environments for wireless sensor networks, which becomes an essential technology towards the ubiquitous era. Two representative environments, TinyOS/nesC and Nano Qplus/C were investigated and the comparison was performed by implementing a typical application including sensing and multi - hop transmission. We experienced and observed that the TinyOS/nesC environment is difficult at initial stage due to the unfamiliar programming model, but the result codes are more compact and have abundant reference implementations. On the other side, Nano Qplus/C environment is easy to adaptable for general purpose programmers and provides more features such as multi-threading and dynamic memory allocation.

연구배경 : 최근에는 의학, 약학, 생물학 등의 여러 분야에서 한의학, 특히 한약을 이용한 새로운 치료제의 개발에 많은 관심을 가지게 되었다. 한의학계에서도 한의학의 국제화, 또는 제재의 다양화를 위해서 이러한 노력을 하여야 할 때이라고 사료된다. 이러한 연구의 일환으로 구강세정 및 치아우식증을 예방하기 위한 한약제의 개발을 위하여 항미생물작용을 지닌 생약제가 구강내 세균에 미치는 영향을 연구하게 되었다. 방법 : 黃連抽出液을 제조하여 Streptococcus mutans 10449의 성장에 미치는 영향을 측정하기 위하여 Todd-Hewitt배지를 이용하여 균집락 형성에 미치는 영향을 측정하였다. 결과 : 黃連이 Streptococcus mutans 10449의 성장을 억제하는 효과를 보였으며 рH의 감소를 유발하여 산생성을 억제함을 알 수 있었다. 결론 : 위의 결과를 근거로 하여 黃連이 치아우식증의 새로운 구강세정제 및 치아우식증예방에 치료제로서 개발할 수 있을 것으로 생각된다. It has been reported that Coptidis Rhizama have an antibacterial effect. The purpose of this study is to know the growth rate &the рH change of Streptococcus mutans 10449 by Coptidis Rhizama. Growth rate was measured by optical densith and рH change was measured by рH meter. The growth of Streptococcus mutans 10449 in the absence of Coptidis Rhizama was more than that in the presence of Coptidis Rhizama irrespective of their concentration. The рH of Streptococcus mutans 10449 in the 10% of Coptidis Rhizama was less than that in the control and 1% of Copyidis Rhizama. These results suggest that Coptidis Rhizama might have an inhibitory effect of growth and acid production of S. mutans 10449. Further study is needed to know the effect onb human gingival fibroblast by Coptidis Rhizama.

Disengagement의 沿革과 意義

趙炳珠 東亞大學校 1964 東亞論叢 Vol.2 No.1

The Scope of this study comprises the following divisions: 1. Preface 2. Historical background of disengagement 3. The 'pro' & 'con' of the realization of this idea 4. The types and their character 5. Conclusions As a result of this study, the writer reached the following conclusions: 1. The idea of disengagement might well be called the idealistic proposal to release the tensions in the given situations. 2. But the two blocs have never reached an agreement on the proposal. This evidence proves that a simple military solution could not solve the basic problems. 3. This is because the basic conflict between the two blocs rests on ideological view points. Therefore, the ideological disengagement is the basic solution of the tensions. 4. But the writer emphasises that even if the result of military disengagement is not so sucessful, it might lead to the foundations of a higher political solution to the tensions.

In the stability analysis of eccentrically loaded foundation, soil properties and loads involve many uncertainties so it is necessary to do stability analysis of foundation that considers the probabilistic properties of each variable. This study is performed to reliability analysis for bearing capacity and settlement of eccentrically loaded foundation by using Monte Carlo Simulation Method. To consider the uncertainty of variables, the soil properties and loads and eccentric length are assumed to be normal distribution random variables. Then it is performed to do sensitivity analysis which is involved to failure probability of bearing capacity and excess probability of allowable criteria of settlement according to varity of each variable. It is thought to be proper that the stability analysis of eccentrically loaded shallow foundation should be analyzed considering uncertainty of variables.
