중등 사회과교과서에 나타난 한·중·일 관계 분석 : 다문화교육의 관점에서 the Perspective of the Multicultural Education
金善美 한국사회과교육연구학회 2003 사회과교육 Vol.42 No.1
본 연구에서는 제7차 교육과정으로 새롭게 개정된 중등 사회과 교과서의 내용과 단원구성을 다문화교육적인 관점에서 검토하고자 하였다. 특히 학생들이 속한 문화권과 그 이웃 문화와 관련된 중학교 1학년 사회과 교과서들의 동아시아 단원 부분을 분석 대상으로 하였다. 본문에서는 먼저 분석의 시각으로써 제시된 다문화교육의 핵심적 개념을 제시하고, 6종 교과서에 제시된 한ㆍ중ㆍ일 삼국에 관한 내용과 단원구성에 대해 비교 분석하였으며, 이에 따라 발견되는 문제점들을 지적하였다. 대부분의 교과서는 삼국의 문화를 하나의 문화권으로 제시하면서 상호 유사성과 차이점을 드러내고자 하였다. 그러나 다문화교육적 관점에 비추어 볼 때 지나치게 중국 중심적인 단원 구성과 문화의 편향된 인식, 문화적 전형에 대한 비판적 인식과 삼국관계의 상호 연계성이 결여된 등 삼국관계 이해교육의 문제점을 드러내고 있는 것으로 지적되었다. This paper attempts to analyze six social studies textbooks provided for recently revised curriculum. It closely looks at one unit of each social studies textbook, titled the development of East Asia, and trys to examine contents, organizations of the unit with the perspective of Multicultural education(MCE). Since MEC perspective was taken as the theoretical framework of the analysis, this paper provides the core concepts of the MCE; the diversity and equity, the similarities and differences among cultures, the removal of misconception of cultures, the identities and respects of cultures, and the understanding of cultures and interrelations among them. It was found that there are several problems that may deteriorate in understanding cultures of East Asian countries. In general, the units of East Asia in social studies textbooks mainly consisted of Chinese history, omitting the most stories of other countries. Moreover, the development of each country was independently described, lacking the coherence of a cultural boundary as East Asia and the interaction among countries. It was also pointed out that even parts of the unit such as topic, introduction, summary questions, inquiry activities needed to be more coherent within a unit in order to clearly reveal the theme of the units.
사회과 학업성취와 관련된 학습동기 유형과 영향요인 분석
김선미 한국사회과교육연구학회 2004 사회과교육 Vol.43 No.3
본 연구는 고등학생들의 자발적인 학습참여를 유도하기 위하여 학생들의 학습동기의 실태를 파악하고 학습동기에 영향력을 미치는 교실수업요인을 실증적으로 검증해내는데 그 목적이 있다. 학습동기는 내적동기, 동일시된 규제동기, 외적동기, 무동기의 유형으로 구분하여 유형별 동기유발의 정도와 학업에 영향을 미치는 학습된 무기력의 경험 정도를 파악하였다. 연구결과 우리나라 고등학생들은 사회교과목 학습에 있어서 내적동기 보다 외적동기가 강하게 작용하였으나 사회과 학업성취의 차이에는 외적동기가 영향을 미치지 않는 것으로 나타났다. 한편, 사회과 학업성취도에 영향을 미치는 학습의 내적동기의 강화에는 수업방식과 교과서가 영향력 있는 요인으로, 동일시된 규제동기의 유발과 학습된 무기력을 경험하는 데에는 수업방식 교사의 태도 교과서가 영향력 있는 요인인 것으로 나타났다. The purpose of this study is to understand high school students's motivation to learn social studies and to find out variables in classroom settings that improve the learning motivatin. For the study, about 500 male and female studnets in high schools are sampled. Survey instruments are developed based on th study of Guay(2000), literature review, and consult with professionals. The types of motivations are classified as intrinsic motivation, identified regulation, extrinsic amotivation and amotivation. Students' experience of helplessness is also surveyed because it may influence on the academic achievement. To analyze data, frequencies, means and standard deviations are run, and t-test and regression analysis are applied using the SPSS program. As a result, it appears that the extrinsic motivation of students is higher than intrinsic motivation and identified regulation. However, the types of motivation that influence on the students' academic achievement are the intrinsic motivation and the identified regulation. It is found that the variables which could influence to Improve students' intrinsic motivation are textbooks and teaching methods. Teachers, textbooks, and teaching methods also increase identified regulation, and decrease the experience of helplessness of learning.

The dramatic increase in the prevalence of obesity and its accompanying comorbidities are major health concerns in Korea. Obesity is defined as a body mass index (BMI) ≥25 kg/m2 in Korea. Current estimates are that 32.8% of adults are obese: 36.1% of men and 29.7% of women. The prevalence of being overweight and obese in national surveys is increasing steadily. Early detection and the proper management of obesity are urgently needed. Weight loss of 5-10% is the standard goal. In obese patients, control of cardiovascular risk factors deserves the same emphasis as weight-loss therapy. Since obesity is multifactorial, proper care of obesity requires a coordinated multidisciplinary treatment team, as a single intervention is unlikely to modify the incidence or natural history of obesity.

<P>Bone marrow-derived mononuclear cells (BMNCs) have been shown to effectively treat ischemic cardiovascular diseases. Because diabetic neuropathy (DN) is causally associated with impaired angiogenesis and deficiency of angiogenic and neurotrophic factors in the nerves, we investigated whether DN can be ameliorated by local injection of BMNCs. Severe peripheral neuropathy, characterized by a significant decrease in the motor and sensory nerve conduction velocities (NCVs), developed 12 weeks after the induction of diabetes with streptozotocin in rats. The injection of BMNCs restored motor and sensory NCVs to normal levels and significantly improved vascular density and blood flow in diabetic nerves over 4 weeks. Fluorescent microscopic observation revealed that DiI-labeled BMNCs preferentially engrafted in sciatic nerves. Whole-mount fluorescent imaging and confocal microscopic evaluation demonstrated that many of the BMNCs localized following the course of the vasa nervorum in close proximity to blood vessels without incorporation into vasa nervorum as endothelial cells at a detectable level. Real-time reverse transcription-polymerase chain reaction analysis showed that the levels of angiogenic and neurotrophic factors were significantly increased in the nerves by BMNC injection. Local transplantation of BMNCs improved experimental DN by augmenting angiogenesis and increasing angiogenic and neurotrophic factors in peripheral nerves. These findings suggest that BMNC transplantation may represent a novel therapeutic option for treating DN.</P>

To elucidate the mechanism of cyclic nucleotides, such as adenosine 3',5'-cyclic monophosphate (cAMP) and guanosine 3',5'-cyclic monophosphate (cGMP), in the regulation of human gastric motility, we examined the effects of forskolin (FSK), isoproterenol (ISO) and sodium nitroprusside (SNP) on the spontaneous, high $K^+$ and acetylcholine (ACh)-induced contractions of corporal circular smooth muscle in human stomach. Gastric circular smooth muscle showed regular spontaneous contraction, and FSK, ISO and SNP inhibited its phasic contraction and basal tone in a concentration-dependent manner. High $K^+$ (50 mM) produced sustained tonic contraction, and ACh $(10\;{\mu}M)$ produced initial transient contraction followed by later sustained tonic contraction with superimposed phasic contractions. FSK, ISO and SNP inhibited high $K^+$-induced tonic contraction and also ACh-induced phasic and tonic contraction in a reversible manner. Nifedipine $(1\;{\mu}M)$, inhibitor of voltage-dependent L-type calcium current $(VDCC_L)$, almost abolished ACh-induced phasic contractions. These findings suggest that FSK, ISO and SNP, which are known cyclic nucleotide stimulators, inhibit smooth muscle contraction in human stomach partly via inhibition of $VDCC_L$.
XPS STUDY ON OXIDE ETCH RESIDUE AND CLEANING
Kim, Jae Jeong,Lee, Eun Gu,Kim, Ik Nyun,Kim, Woo Shik,Kim, Seon Mee 한국화학공학회 1992 Korean Journal of Chemical Engineering Vol.9 No.4
A layer structure, chemical composition and cleaning process of oxide dry etch residue on silicon substrate were studied. It was observed that the structure of the etch residue consisted of CF_x-polymer/SiO_yC_z. The ratio of y and z in SiO_yC_z layer is monotonously changing with depth: y/z is maximum at the interface of CF_x-polymer and SiO_yC_z, and minimum at the interface of SiO_yC_z and silicon substrate. Two step cleaning was proposed: dry and wet cleaning. The most effective process was silicon light etch (CF₄/O₂ REMOTE PLASMA), followed by NH₄OH-H₂O₂ mixture and HF dip. From X-Ray Photoelectron Spectroscopy (XPS) data, it was found that oxide etch residue was completely removed by dry and wet cleaning.

<P>Cytogenetic testing is important to ensure patient safety before therapeutic application of mesenchymal stromal cells (MSCs). However, the standardized methods and criteria for the screening of chromosomal abnormalities of MSCs have not yet been determined. We investigated the frequency of cytogenetic aberrations in MSCs using G-banding and fluorescence in situ hybridization (FISH) and suggest reference values for aneuploidy in MSCs. Cytogenetic analysis was performed on 103 consecutive cultures from 68 MSCs (25 adipose-origin, 20 bone marrow-origin, 18 cord blood-origin, and 5 neural stem cells; 8 from adipose tissue of patients with breast cancer and 60 from healthy donors). We compared the MSC aneuploidy patterns with those of hematological malignancies and benign hematological diseases. Interphase FISH showed variable aneuploid clone proportions (1%-20%) in 68 MSCs. The aneuploidy patterns were asymmetric, and aneuploidy of chromosomes 16, 17, 18, and X occurred most frequently. Clones with polysomy were significantly more abundant than those with monosomy. The cutoff value of maximum polysomy rates (upper 95th percentile value) was 13.0%. By G-banding, 5 of the 61 MSCs presented clonal chromosomal aberrations. Aneuploidy was asymmetric in the malignant hematological diseases, while it was symmetric in the benign hematological diseases. We suggest an aneuploidy cutoff value of 13%, and FISH for aneuploidy of chromosomes 16, 17, 18, and X would be informative to evaluate the genetic stability of MSCs. Although it is unclear whether the aneuploid clones might represent the senescent cell population or transformed cells, more attention should be focused on the safety of MSCs, and G-banding combined with FISH should be performed.</P>
