  • 본 연구는 우리 나라의 성인들이 자신의 초중등 학교 시절 경험하였던 학교 과학교육에 대해 어떤 종류의 즐거운 혹은 괴로운 기억들을 현재까지 갖고 있는가를 탐색하였다. 성인들은 오래 전 경험하였던 매우 인상적인 활동이나 장면들을 통해 학교 과학교육을 기억할 것이고, 이러한 기억은 그들의 학교 과학교육에 대한 전반적인 태도에 결정적인 역할을 할 것이다. 따라서 성인들의 학교 과학교육에 대한 이러한 기억들을 살펴보면, 학교 과학교육의 특징을 이해하고 장기적으로 학교 과학교육을 보다 즐거운 경험의 장으로 만드는 데 도움이 될 것이다. 본 연구는 소규모의 설문 조사를 통해 이루어졌으며, 설문 대상은 대구지역의 30-50대 성인 88명이었다. 설문은 현재 과학과 관련된 특정한 직업을 갖고 있지 않은 사람을 대상으로 하였으며, 설문에서 응답자들은 자신들의 초중등 학교 과학교육을 받으면서 가장 즐거웠던 기억과 가장 괴로웠던 기억이 구체적으로 무엇이며 이러한 경험은 초중고 어느 때이었는가를 응답하였다. 성인들이 가장 즐거웠던 기억으로 지적한 것은 실험 실습 활동(65.9%), 야외학습 활동(19.3%) 등으로 전통적인 교실수업 이외의 활동이 약 86%로 나타났다. 그리고 효과적인 교실수업, 교사의 인성적 특징, 과학전람회 참가 등의 경험을 언급한 경우도 부분적으로 있었다. 성인들이 가장 괴로웠던 기억으로 지적한 것은 따분한 교실수업(51.1%), 실험 실습 활동의 부정적인 측면(28.4%) 등으로 나타났으며, 부분적으로 과다한 숙제, 교사의 인성적 특징, 야외학습 활동, 과학수업의 부재 등을 지적한 경우도 있었다. 또한 전체적으로 즐거웠던 기억은 국민학교 시절의 경험에서(56.8%), 반면 괴로웠던 기억은 고등학교 시절의 경험에서(44.3%) 많이 나타났다. 특히, "개구리 해부 실험" 의 경우, 7명이 가장 즐거웠던 기억으로 8명은 가장 괴로웠던 기억으로 언급하여 매우 상반된 견해를 나타냈다. 따라서 동일한 활동일지라도 학생들에게는 매우 상반된 경험으로 작용하게 되며, 이 경우 생명체에 대한 과학실험의 윤리적 문제와 이에 대한 갈등을 분명하게 드러냈다.

  • Objectives: The objective of this study was to investigate the correlation between insufficient sleep and visuospatial memory in adolescents using a computerized neurocognitive function test. Methods: A total of 103 high school students (26 males and 77 females; mean age $17.11{\pm}8.50years$) without a serious psychiatric problem was recruited. All subjects were requested to complete a self-report questionnaire about weekday total sleep time and weekend total sleep time. The epworth sleepiness scale (ESS) and the beck depression inventory (BDI) were administered to measure daytime sleepiness and symptoms of depression. Seven subsets of the Cambridge Neuropsychological test automated battery were examined to assess visuospatial memory. Results: After controlling for age, sex, ESS, and BDI, longer weekend total sleep time was correlated with poor performance on delayed matching to sample (r = -0.312, p = 0.002) and immediate recall on pattern recognition memory (r = -0.225, p = 0.025). Increased weekend catch-up sleep time was correlated with poor performance of delayed matching to sample (r = -0.236, p = 0.018), immediate recall on pattern recognition memory (r = -0.220, p = 0.029), and delayed recall on pattern recognition memory (r = -0.211, p = 0.036) after controlling for age, sex, ESS, and BDI. Conclusion: This study showed that increased weekend catch-up sleep time reflecting insufficient weekday sleep were associated with poor performance in delayed recall tasks of visual memory. This finding suggests that insufficient sleep during adolescence might produce a decline of visuospatial memory.

  • Objectives : The deficit of recognition memory has been found as one of the common neurocognitive impairments in patients with schizophrenia. In addition, they were reported to fail to enhance the memory about emotional stimuli. Previous studies have shown that bilateral eye movements enhance the memory retrieval. Therefore, this study was conducted in order to investigate the memory enhancement of bilaterally alternating eye movements in schizophrenic patients. Methods : Twenty one patients with schizophrenia participated in this study. The participants learned faces (angry or neutral faces), and then performed a recognition memory task in relation to the faces after bilateral eye movements and central fixation. Recognition accuracy, response bias, and mean response time to hits were compared and analysed. Two-way repeated measure analysis of variance was performed for statistical analysis. Results : There was a significant effect of bilateral eye movements condition in mean response time(F=5.812, p<0.05) and response bias(F=10.366, p<0.01). Statistically significant interaction effects were not observed between eye movement condition and face emotion type. Conclusions : Irrespective of the emotional difference of facial stimuli, recognition memory processing was more enhanced after bilateral eye movements in patients with schizophrenia. Further study will be needed to investigate the underlying neural mechanism of bilateral eye movements-induced memory enhancement in patients with schizophrenia.

  • Objectives: The purpose of this study was to confirm the anti-amnesic effects of Bunsimgieum (BSGE) through its favorable acetylcholine (ACh) and, acetylcholinesterase (AChE) activity, choline acetyltransferase (ChAT) mRNA expressions, and antioxidant effect on scopolamine (Sco)-induced memory impairment in C57BL/6 mice. Methods: Six groups, a total of 20 intact or 100 Sco-induced mice were used in this study, based on their body weight. Half of each group underwent passive avoidance tests and the measurement of hippocampus AChE activity, ACh content, and ChAT mRNA expression, The remaining half of each group underwent a Morris water-maze test and antioxidant defense system measurement as well. Results: Significant reductions in the step-through latency times from the passive avoidance test and reductions in the escape latency times from the Morris water-maze test were observed with increases of hippocampal AChE activities and, reductions in ACh contents and ChAT mRNA expression in hippocampus, as a result of Sco intraperitoneal treatment, in this study. Additionally, the increases in cerebral cortical MDA levels and, reductions in GSH contents, SOD activities, and CAT activities were demonstrated in the Sco control mice compared with the intact vehicle control mice, respectively. However, 28 days of consecutive oral pre-treatment of BSGE hot water extracts of 400, 200, and 100 mg/kg, respectively, markedly and dose-dependently inhibited Sco treatment-related amnesia. Conclusions: The results demonstrate that the oral administration of BSGE hot water extracts reduces Sco-induced memory impairment, through preserving ACh, related to ChAT mRNA expressions, causes AChE inhibition, and enhances the cerebral antioxidant defense system.

  • This study aims to explore the 'affective value' of records. Traditionally, records have been evaluated as having evidence value, information value, and artificial value. However, the 'affective turn' in the humanities and social sciences, which began in the 1990s, calls for discussion on the affective value of records. The overseas archive academia is in full swing discussing the emotional value of records after the 'affective turn'. However, there is no emotional discussion on records in the domestic archive academia. This study first conducts theoretical discussions to overcome these domestic limitations and explore the emotional value of archives in earnest. Following the theoretical discussion, a specific case will be dealt with next. As a representative storage of affect, which records the pain, sadness, and condolences of the domestic disaster era, this study investigates the record management case of the 4.16 Memory Storage. The Ferry Sewol disaster, which provided a dramatic opportunity to witness the unexpected ripple effect of affect in Korea, and the 4.16 Memory Storage as a recording activity, can be seen as a representative example of affective recording of the pain and sadness of survivors of the trauma incident. It will capture the differentiation of affet recording, which is different from the record management practice, and demonstrate empirically how this differentiation is implemented from collection to evaluation and service through the '4.16 Memory Storage'.

  • Objectives: The objective of this study was to observe the anti-amnesic effects of Yukmijihwang-tang (YMJHT), on the scopolamine (Sco)-induced memory impairment in C57BL/6 mice through its favorable acetylcholine (ACh). Also, to observe acetylcholinesterase (AChE) activity, Choline acetyltransferase (ChAT) mRNA expressions, and antioxidant effect. Methods: Six groups, with a total of 20 normal and 100 Sco treated mice were selected based on their body weights after 1 week of acclimatization, were used in this study as follows. Half of the mice in each group were used for passive avoidance task tests and hippocampus ACh content, AChE activity and ChAT mRNA expression measurement, and the remaining half in each group used for Morris water maze test and measurement of cerebral antioxidant defense system. Results: Amnesia due to AChE activations and destroyed cerebral cortex antioxidant defense systems were markedly and dose-dependently inhibited after 28 days of continuous oral pre-treatment with YMJHT 400, 200 and 100 mg/kg, respectively. The overall effects of YMJHT 400 mg/kg were similar to those of tacrine 10 mg/kg. Conclusions: Based on the results, it was established that oral administration of YMJHT favorably alleviates Sco-induced memory impairment, through preservation of ACh, mediated by up-regulation of ChAT mRNA expressions and related AChE inhibition and augmentation of cerebral antioxidant defense system, at least in a condition of this experiment. The overall effects of YMJHT 400 mg/kg were similar to those of tacrine 10 mg/kg.

  • Objectives: The purpose of this study is to review clinical studies and investigate the efficacy and safety of oriental medicine on memory in menopausal women. Methods: 'menopause', 'memory', 'oriental medicine' were searched on 4 online databases (Cochrane Library, Pubmed, CNKI, OASIS). Randomized controlled trials (RCTs) that evaluated menopausal memory with oriental medicine treatment were included. The methodological quality of each RCT was assessed by using Cochrane risk of bias tool. Results: 8 RCTs were selected among 1067 articles. The overall risk of bias was evaluated as uncertain. 5 studies showed that oriental medicine alone was significant effective, but 1 long-term study with the same oriental medicine did not sustain the effect, and 2 studied were not statistically significant. Conclusions: Oriental medicine can be an effective option for improving memory in menopausal women. but considering the small number and quality of studies, inconsistent and insufficient evidence, further well-designed studies are needed to confirm the efficacy and safety of this treatment.

  • The purpose of this study was to examine the effects on the academic achievement and learning satisfaction according to the presentation method of the multimedia materials for 'transportation technology' units of technology home economics subject. The subjects were assigned in third conditions; Text type explanation class, multimedia class and multimedia video class with narration. The data of six evaluation questions obtained from the survey of 93 high school girl were analyzed using SPSS program. The results of the study were as follows : First, in the learning satisfaction average level(M) of the students' overall responses to the questions, multimedia teaching learning class(experimental group 1) is the first(M=4.14), multimedia video class with narration(experimental group 2) is the second(M=3.16), and instructor-led class(control group) is the third (M=2.63). Therefore, the teaching learning multimedia class(experimental group 1) was most effective. Second, looking at the correlations between the students' responses to the questions, in an interesting class, the students have a retentive memory and comprehension, but a lower concentration can not a retentive memory. Third, multimedia teaching learning class(experimental group 1) has the best degree at the level of academic achievement, but instructor-led class(control group) and multimedia video class with narration(experimental group 2) have similar degree in the second place. To increase academic achievement, an instructor-led class is important to arouse interest and a multimedia video class with narration is required ways to improve level of concentration.

  • Objective : Impaired working memory has been known to play an important role in the pathophysiology of obsessive-compulsive disorder (OCD) with growing evidence. Delayed matching-to-sample task (DMST) is a working memory task which have an advantage in analyzing several different working memory processes in one task. However, most of the studies have failed to reveal the working memory impairment with the DMST. The aim of this study was to identify whether working memory deficit in OCD can be evaluated with the DMST. Methods : The participants included 20 OCD patients and 20 healthy volunteers. Working memory was evaluated with the DMST with two different working memory loads. Accuracy of response and mean response time were measured. Results : OCD patients showed a significantly longer reaction time and lower accuracy in DMST compared to healthy controls in the task with high working memory loads. Moreover, the difference in accuracy showed interaction with the working memory load. Conclusion : The present results indicate that working memory deficit in patients with OCD can be evaluated with the DMST. The findings also suggest that previous negative behavioral results using the DMST were from low working memory load of the task.
