배둘련,안성우,백유순 한국특수아동학회 2002 특수아동교육연구 Vol.4 No.1

본 연구는 청각 장애 학생들, 청각 장애 학교에 근무하는 교사들, 그리고 청각 장애 아동을 자녀로 둔 부모들의 수화와 선호하는 수화에 대한 태도를 조사하기 위해 실시되었다. 본 연구에서는 구체적으로 세 집단의 수화에 대한 태도가 차이가 있는가? 와 세 집단이 선호하는 수화 유형에 차이가? 있는가를 조사하였다. 본 연구에 사용된 피험자는 141명에 청각 장애 학생들, 140명의 청각 장애 학교 교사들, 그리고 120명의 부모들이다. 설문지는 3부분으로 구성되어 있는 데 이는 인구 통계학적 특성을 묻는 문항들과 수화에 대한 태도를 묻는 문항들 그리고 선호하는 수화 유형을 묻는 문항들이고 Likert 5점 척도를 사용하였다. 이 문항들의 신뢰도는 각각 .85, .83, .76이다. 본 연구의 결과는 다음과 같다. 첫째, 교사들의 수화에 대한 태도가 부모들이나 학생들의 태도보다 더 긍정적이었다. 둘째, 학생들은 성인 농자들이 사용하는 수화를 더 선호하는 것으로 나타났고 교사들은 국어 어순에 맞게 표현하는 수화를 더 선호하였다. 이것은 성인 농자들이 사용하는 수화가 학생들의 인지 처리 양식에 더 부합하기 때문에 이해하기가 국어 어순대로 표현한 수화보다 더 쉬울 것이기 때문일 것이다. The purpose of the present study is to investigate the attitudes toward sign language in deaf students, teachers and deaf students' parents using sign language as a communication method. The following research questions is addressed in the study: (1) What's difference of a sign language perception among three groups? (2) What's difference of preferred sign language of three groups? The subjects were 141 deaf students, 140 teachers and 120 parents who have deaf child. The questionnaire was developed based on previous literature and consisted of three parts: (1) Background information (2) Sign language perception (3) Sign language preference. The reliability of this questionnaire was .85, .83, and 76, respectively according to Cronbach alpha. The respondents marked the items on the questionnaire using the Likert Scale. The data were analyzed using ONE-WAY ANOVA and frequency analysis with SPSS for windows. The results are as follows First, teachers' sign perception indicated higher scores than deaf students' and their parents' scores. Therefore teachers estimated sign language highly as useful communication mode for students with hearing impairment. There's no significant difference in the students group according to their parents' hearing status and experiences of integration. And in teachers group, there is also no significant difference regardless of their school level, teaching experience and hearing status. But in parents's group, there's significant difference according to their children's school level and their educational background. The parents who have younger children got lower scores than other parents who have old students, and the parents with higher educational background got slower scores than others with lower educational background. It meant that their attitude toward sign language is comparatively negative. Second, students preferred sign language used by deaf adults to grammatical sign language. But teachers appeared to have favor of grammatical sign language. They are using sign language simultaneously with speech, and using it in a Korean word order. However it is unclear that which sign language type the parents group prefer to because of their poor signing ability. These results suggest that Korean sign language used by deaf adults be not widely used. However, teachers' Korean sign language skill should be emphasized and improved.

The aim of this study is to understand Beloved better with the consideration of family and community. It seems to be important for the blacks to get both family and community. Especially, the slave women really wanted to get their own husband, children. Like Sethe, most of the black women did their best to have their children to get freedom under slavery. After all, Sethe chose the worst thing, the murder of a daughter. It was followed by the death of mother-in law, Baby Suggs, and the flight of two sons. We can say her family was broken first by the slavery, and then by Sethe. After that, she was excluded not only by her family, in which were a mother-in law, two sons, and a youngest daughter, but also by the community. But the characters show the possibility of rejoining the new family through the text. Therefore, through the study of family, we can understand the self-recognition of main characters. This study is based on the premise that we need to understand the community of black women to get the correct meaning of Morrison's works. For the slave blacks, it was necessary to make their own community under the slavery. Of course, the people can gain their selfhood and live in relation to others. In this text, the community thus performs the function of the extended 'mother'. In the end of this text, the community reclaim Sethe as a member of that community of mothers and children despite separations, deaths, and violations. Sethe, like Denver, is accepted and remembered into the community of women Beloved is once again run out of 124, this time apparently for good.

섬잣나무의 胚로부터 器內胚培養을 통하여 온전한 植物體를 유기시키기 위해 培地의 造成과 植物 生長調節劑의 影響을 儉素하였다. 1. 基本 培地로서 木本類의 組織培養에 양호한 GD, MS. LM배지를 기본으로 하여 實驗한 結果 GD와 MS가 섬잣나무의 胚培養에 적당하였다. 2. GD, MS, LM 배지에 auxin, cytokinin으로서 0.1ppm, 0.5ppm, 0.05ppm을 添加하여 4周間 培養하였을때 주로 GD배지에서 NAA 0.1ppm, MS배지에서는 2, 4-D 0.1ppm에서 Shoot 生長이 매우 좋은 結果를 나타냈다. 3. 식물체 유기를 위해서는 Callus段階를 거치지 않고 生長하는 胚가 있는 반면 植物 生長調節劑에 따라 Callus화 되는 胚가 있는데 현재 Callus에서 體細胞 胚 유도를 위해 4개월 동안 배양하고 있는데, 이의 연구는 섬잣나무의 組織培養을 利用 大量增殖에 많은 도움을 줄 것이다. In order to induce a complete plant from embryo of Pinus Parviflora GD, MS, LM media and plant regulators such as 2, 4-D, NAA, 2, 4-D+BAP were employed for in vitro culture media. 1. The best condition for the embryo culture was GD and MS system. 2. When the addition of plant growht regulators (0.5, 0.1, 0.05ppm) in the GD, MS and LM media, generaly GD medium supplemented with 0.1ppm of NAA, MS medium supplemented with 0.1ppm of 2, 4-D showed the best result. 3. Present studies have been investigated of callus for four months, and going to keep on inducing somatic embryo in vitro embryo culture.

Antidepressant, Sedative and Hypnotic effects of Vaccinium bracteatum extract: An in vitro and in vivo Characterization of the Underlying Mechanism

Vaccinium bracteatum Thunb. (VB) are a component of traditional herbal medicines found in East Asia, specially, fruit is commonly known as the oriental blueberry in Korea. The present study aimed to evaluate the mechanisms underlying the antidepressant, preventing oxidative stress and insomnia of water extract of VB fruit (VBFW) using in vitro and in vivo models. First, since the serotonin neurotransmitter system is hypothesized to contribute to depression, we studied the effects of water extract from VBFW on the serotonin receptors (5-HTRs)-related activities in Chinese hamster ovary (CHO)-K1 cells transfected with the human 5-HT1, 5-HT2, 5-HT3, 5-HT4, 5-HT6, and 5-HT7 receptors. VBFW produced the antagonistic effects at the 5-HT2A receptors, and showed the agonistic effects at the 5-HT1A receptors, which could possibly produce antidepressant-like effects. Next, it was studied by using animal models predictive of antidepressant-like effects. The effects of VBFW were studied in normal and 4-Chloro-DL-phenylalanine methyl ester hydrochloride (PCPA)-induced serotonin-depleted mice. These results suggest that evidence of the antidepressant-like effects of VBFW includes the decreased immobility time during the forced swim test (FST) in mice that is caused by a decrease in the levels of serum corticosterone (CORT), as well as increased serotonergic neurotransmission. Moreover, this study provides an evidence that the antidepressant-like effects of VBFW in mice exposed to chronic restraint stress (CRS) exhibited significantly reduced immobility time and increased swimming times in the FST, and increased locomotor activity in the OFT. In addition, CRS mice treated with VBFW exhibited significantly decreased the hypothalamic-pituitary-adrenal (HPA) axis and oxidative stress (e.g., glutamate and MDA levels), but upregulated brain monoamine neurotransmitters (e.g., 5-HT, dopamine, norepinephrine) and the extracellular signal-regulated kinase (ERK) and protein kinase B (Akt) phosphorylation. Furthermore, since depression can lead to sleep problems, the sedative and hypnotic effects of VBFW in an animal model and alterations to the γ-aminobutyric acid (GABA)-ergic system were also studied. VBFW significantly reduced the sleep latency and increased the total sleep duration during pentobarbital-induced sleeping behaviors in mice, which are possibly associated with upregulation of the glutamate decarboxylase (GAD)65/67 protein and GABAA receptor subunits (α5, β1, and β2). In conclusion, the antidepressant effects of VBFW were possibly mediated by regulation monoamine neurotransmitters in basis of their effects on 5-HT2A and 5-HT1A receptors and ERK/Akt phosphorylation, and prevention of HPA axis dysfunction. Furthermore, VBFW induces sedative and hypnotic effects by regulating the serotonergic and GABAA-ergic systems. These results suggest that the VBFW might be an effective natural therapeutic agent for stress and depression disorder.
