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.

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.

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>

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.

The objective of present study is to develop a software for simple numerical analysis that can be used to evaluate the efficiency of solar collector units using evacuated glass tubes. This analysis was performed by taking energy balance to a given physical model and applying the total energy factor method proposed by Beckman. In present study, focus was concentrated on the effect of collector surface coating on the collector efficiency. The results are as as follows; 1) The temperature distribution obtained from the analysis with just 19 grids shows good agreement with the experimental data within 2%. So, the developed software can be used to determine the optimum design parameters. 2) The collector efficiency depends mostly on the radiation property of collecting surface coating material ; η ≒ 60-80% for a black chrome selective coating and ; η ≒ 20-60% for a black paint coating.

Recently the usage of mobile devices which enable the accessibility to Internet has been dramatically increased. Most of the mobile services. however, so far tend to be simple such as infotainment service. In order to fully taking advantage of wireless network and corresponding technology, personalized web service based on user's context could be needed. Meanwhile, optimization techniques have been vitally incorporated for optimizing the development and administration of electronic commerce. However, applying context-aware optimization mechanism to personalized mobile services is still very few. Hence, the purpose of this paper is to propose a methodology to incorporate optimization techniques into personalization services. Multi agent-based web service approach is considered to realize the methodology. To show the feasibility of the methodology proposed in this paper, a prototype system, CAMA-myOpt(Context-Aware Multi-Agent system for my Optimization), was implemented and adopted in mobile comparative shopping.

To investigate the relationship between several intraoral soft tissue lesions(hairy tongue, lichen planus, recurrent aphthous stomatitis, oral candidiasis, glossitis and oral herpetic lesion) and oral mucosal keratinization, exfoliative cytological smear on intraoral mucosal surfaces were performed on each number of patients and 25 controls keratinization cell(yellow-stained cell) ratio was then measured. In hairy tongue, there was no significant difference between patient group and control group in all kind of cells. Only blue cell ratio of wemen was more than of men in patient group. In inchen planus, there was no difference between patient and control group in yellow cell ratio. Red cell ratio in the control group was more than in the patient group. Blue cell ratio in the patient group was more than that in control group. But there was no sex predilection between both groups in the ratio of all kind of cells. In recurrent aphthous stomatitis, Yellow cell ratio in the control group was more than that in the patient group. Red cell ratio in the control group was more than that in control group. Blue cell ratio in the patient group was more than that in control group. But there was no sex predilection between both groups in the ratio of all kind of cells. In oral candidiasis, Yellow cell ratio in the control group was more than that in the patient group. Red cell ratio in the control group was more than that in control group. Blue cell ratio in the patient group was more than that in control group. There was no sex predilection between both groups in yellow cell ratio. Red cell ratio of wemen was more than of men in patient group. Blue cell ratio of men was more than of wemen in patient group. In herpetic lesions, there was no difference between patient and control group in yellow cell ratio. Red cell ratio in the control group was more than in the patient group. Blue cell ratio in the patient group was more than that in control group. Yellow cell ratio of wemen was more than of men in control group. Red cell ratio of men was more than of wemen in control group. Blue cell ratio of men was more than of wemen in patient group. In glossitis, Yellow cell ratio in the control group was more than in the patient group. There was no difference between patient and control group in red cell ratio. Blue cell ratio in the patient group was more than that in control group. Yellow cell ratio of wemen was more than of men in control group. Red cell ratio and blue cell ratio of men were more than of wemen in control group. According to above results, the ratio of keratinized cell in atrophic, ulcerated, or pseudomembranous lesions was lowered than in control, but the ratio of keratinized cell in keratotic, vesicular or lesions on keratinized surface lesions had no difference to control group. Thus, keratotic, vesicular or lesions on keratinized surface lesions have not closely relation to mucosal keratinization. And, there was a little sex predilection between men and wemen in mucosal keratinization.

N-cadherin이 배양 계배 근아세포에서 발현되는 유전자에 미치는 영향

안병태,김영주 가톨릭대학교 자연과학연구소 2003 자연과학논문집 Vol.24 No.-

근아세포는 여러 단계의 근육형성 프로그램을 거쳐 다핵의 근관세포를 형성하며, 근특이 단백질의 합성 및 축적이 일어난다. 근특이 단백질이 합성은 유전자 조절 단백질인 Myo D, myogenin, Myf-5 그리고 MRF-4 등에 의해 조절되며, 이들 단백질이 동형접합체나 이형접합체를 형성함에 따라 DNA와 결합하여, 전사를 조절한다. 근아세포가 응집을 하기 위해서는 cell adhesion molecule이 필요하며, 이 과정에서 칼슘 의존적인 cell-cell adhesion molecule로서 생쥐와 닭의 뇌세포에서 발현되는 N-cadherin이 관여한다. N-cadherin은 골격근 세포나 그 밖의 많은 세포에서도 태아시기에 일시적으로 발현되며, 분화초기에 근아세포에서 발현되어 근세포간의 집합등에 관여한다. 본 연구는 N-cadherin이 근육에서 일시적으로 발현되는 것에 초점을 맞추고, anti-N-cadherin antibody(NCAD2)를 사용하여 N-cadherin을 억제함으로써 발생하는 근육분화의 형태적, 생화학적 변화를 분석하였다. 근아세포 성장에 NCAD2를 처리함에 따라 형태적 분화양상의 차이를 관찰하였고, 융합의 정도가 감소되어 나타났다. 이러한 분화에 작용하는 기작을 보기 위하여 7.5k의 cDNA chip을 사용하여 실험을 수행하였다. 이 실험을 통하여 NCAD2를 처리하였을 때 근세포 분화동안 발현되는 여러 유전자의 발현이 변화하는 것을 관찰하였다. 근세포분화과정에 관여하는 것으로 알려져 있는 Wnt 경로, TGF-beta 경로, ubiquitin경로가 작용하는 것으로 추정할 수 있었다. 이 중에서 근분화에 관여하는 유전자만을 선별하였고, 또한 calponin, integrin, ADAM15, ARNT-like 1 등이 세포-세포, 세포-기질간의 상호 관계에 관련된 유전자의 발현이 증폭됨을 알 수 있었다. 또한 NCAD2를 처리했을 때, 근세포 분화동안 발현되는 MyoD이 발현이 단백질 수준에서 억제됨을 관찰하였다. 이러한 결과들을 종합하여 세포 상호작용을 중재하는 N-cadherin이 근세포 분화에 요구되는 여러가지의 경로에 중요한 역할을 하는 것을 알 수 있었다.

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.
