본 연구의 목적은 필자가 개발한「VPE 프로그램」`Verbal Plan and Evaluation program: 언어적 계획·평가 프로그램`이 만 3-5세 유아의 자기조절력에 미치는 효과를 검증하는데 있다. 이를 위해 이 연구에서는 통제집단에 처치를 가하지 않은 사전·사후 검사 설계`untreated control group design with pretest and posttest` 방법을 적용하였다. 연구대상은 서울지역에 위치한 어린이집 유아 만 3세 37명, 만 4세 37명, 만 5세 39명 등 총 113명이었고, 효과를 측정하기 위한 도구로는 필자의 ``영유아 자기조절력 측정도구``가 사용되었다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 「VPE 프로그램」은 만 3-5세 유아의 자기조절력을 향상시킨다. 둘째, 「VPE 프로그램」이 유아의 자기조절력에 미치는 영향은 연령별로 차이가 있다. 셋째, 개인 내적 요인`연령, 성별, 지능`을 통제했을 때에도 「VPE 프로그램」은 유아의 자기조절력 향상에 효과적이다. 이러한 사실들은 만 3세-5세 유아의 자기조절력을 증진시키기 위해서는 유아교육기관에서 자유선택활동 시간에 「VPE 프로그램」을 적용하는 것이 필요함을 시사한다. Recent neuroscience research in the brain development of children stresses that early childhood years are optimal for nurturing a healthy propensity for self-regulation. Building upon this neuroscience finding, this study investigates the efficacy of the Verbal Plan and Evaluation `VPE` program which guides young children in verbally planning, implementing, and verbally evaluating their choice of activities during free play time in terms of its effect on self-regulation development. Using the Untreated Control Group Design with Pre-and Post-test, subjects, totaling 113 children `37 children at age three, 37 children at age four and 39 children at age five` all enrolled in a child care center in Seoul, were given pre-and post-tests of Yang`s SREC `Self-Regulation in Early Childhood` Scale to measure their self-regulation. The findings of the study are as follows: First, the VPE program for 3-5 year-old improved their self-regulation ability. Second, the VPE program`s effects on the children`s self-regulation were different among the three age groups, indicating the influence of age on developmental capacity. Third, the VPE program improved the self-regulation of all of the 3-year-old, 4-year-old and 5-year-old children even when internal variables including age, gender and intelligence were taken into account. In other words, the VPE program is an effective program for developing self-regulation in 3-year-old, 4-year-old and 5-year-old children. Moreover, the components of the VPE program can be used in a variety of early childhood settings to encourage the plasticity of healthy self-regulation growth.

<P>Creating a plant-cell suspension culture involves first transferring the callus into liquid media, but there are no objective criteria for selecting the location of the callus to be transferred. In this study, inner and outer cells of <I>Catharanthus roseus</I> with various elicitors in solid-state cultures were differentiated by <SUP>1</SUP>H NMR (nuclear magnetic resonance) spectrometry and principal component analysis (PCA). It was found that the samples of various elicitors and relative locations could be separated in PCA-derived score plots. Especially, there was a clear separation between nontreated samples and those cotreated with silver nitrate and methyl jasmonate. Loading-plot analysis was therefore applied to data obtained from nontreated samples and those cotreated with silver nitrate and methyl jasmonate to determine the separation of major metabolites on score plots. The levels of valine, lactic acid, threonine, alanine, arginine, acetic acid, malic acid, succinic acid, citric acid, asparagine, choline, lactose, fumaric acid, phenylalanine, tryptophan, and formic acid were higher in the inner callus than in the outer callus, whereas 2-oxoglutaric acid, oxalacetic acid, sucrose, and glucose dominated in the outer callus. The results obtained in this study suggest that inner and outer calli can be differentiated by <SUP>1</SUP>H-NMR-based metabolomic analysis.</P>

<P>Fermented soybean paste (doenjang, FSP) is a traditionally fermented Korean food produced by fermentation with various microorganisms that is known to exhibit various beneficial bioactivities. To investigate the changes in nonvolatile metabolites of FSP during fermentation, samples produced with six fermentation times were analyzed using an <SUP>1</SUP>H nuclear magnetic resonance spectroscopy (NMR)-based metabolomics technique. This revealed clear separation of 50% methanol extracts of the FSP samples with different fermentation times in the principal component plots by combining PC1 and PC2, which cumulatively accounted for 94.2% of the variance. Major compounds contributing to the separation of 50% methanol extracts of FSP with various fermentation times were isoleucine/leucine, lactate, alanine, acetic acid, glutamine, choline, tyrosine, and phenylalanine. In addition, the <SUP>1</SUP>H NMR spectra of chloroform extracts were separated mainly by a combination of PC1 and PC3, which accounted for 72.6% of the variance. The present study suggests the usefulness of a <SUP>1</SUP>H NMR-based metabolomics approach to discriminate FSP samples subjected to different fermentation times, and this is the first report regarding metabolomic profiling of FSP.</P>
Toward One Korea Examination of Early Childhood Education and Care in South and North Korea
Ok Seung Yang 한국유아교육학회 2003 INTERNATIONAL JOURNAL OF EARLY CHILDHOOD EDUCATION Vol.9 No.2
The two Koreas, the South and the North, differ drastically in what seem to be the most fundamental of ways, Many Koreans still, however, hold hope for a unified homeland and therefore important to examine the inevitably problematic issues in early childhood education and care that will be encountered when the two Koreas are unified. The institutions of early childhood education and care on each side of the DMZ evolved under different ideologies and organizational principles each ideology promoted. The issue of early childhood education and care, which is directly linked to every nation‘s future, will be especially difficult to bridge between a North that uses early childhood education and care as one of its main tools for maintaining Its communist system and a South that understands early childhood education and care in a more private context as part of an open competitive system. Given these disparities, preparation for an early childhood education and care post-unification era framework must begin now. Therefore, this research presents a direction for post-unification early childhood education and care by comparing and analyzing how the systems were developed on both sides of the peninsula following the division of Korea. To this end, South Korean and North Korean early childhood education and care ideologies legal systems, administrative systems, management policies, enrollment rates, costs, early childhood, teacher, policies and operating practices are scrutinized
