This paper is to develop teaching procedures of low achievers in mathematics by using mindmaps. For this, we firstly set the teaching process on basis of literature research. And then we choose four subjects who had serious problems of both memory and mathematics achievement. we also choose the several topics of geometry and measure which could be a big burden of memory as stuff for mindmap activities. The results led us to that using mindmap activities in learning and teaching mathematics could effect on that kind of students' mathematical achievement and mathematical attitude as well as retention of mathematical concepts. It implied that we could develop individual programs for students who have different problems in learning mathematics.

Objective : This study was conducted to investigate the effects of iPad applications on improvement of attention and short-term memory in mild dementia. Methods : A single-case experimental study using A-B-A design was conducted. A total of 20 sessions, including 5 each for baseline phase A and A' and 10 for the intervention phase, were provided to the subject. Interventions were only provided during the intervention phase and were iOS-based iPad applications named "Memorado-Moving Balls" and "Circles." "Fit Brains-Matching Pairs" and "Fit-Brains-Spot the Difference" were used for each session to evaluate attention and short-term memory. MMSE-K, K-TMT-e A and B, and DST assessment tools were used pre- and post-intervention to assess attention and memory. Result : Fit Brains scores indicated improvement in both attention and memory during the intervention phase. K-TMT-e A showed 3 increased correct points and 3 reduced error points, and B showed 7 increased correct points and 2 reduced error points in post-tests, but the DST and MMSE-K showed no meaningful change. Conclusion : This single-case study identified improvements in attention and short-term memory in a person with mild dementia using iPad applications. Further studies regarding different applications and larger samples with long-term designs are necessary.

In the present study, we examined the effect of the aqueous extract of Rubus coreanus Miquel (RCM-Ex) on scopolamine-induced memory impairment in male ICR mice. Mice were fed the diet containing 100 mg/kg body weight/day of RCM-Ex for 4 weeks. To induce amnesia, scopolamine (an antagonist of muscarinic acetylcholine receptor, 1 mg/kg of body weight) was intraperitoneally injected into mice 30 min before starting the behavior tests. RCM-Ex reversed scopolamine-induced memory impairments in mice as evidence by the passive avoidance test and Morris water maze test. In addition, acetylcholineasterase activities were decreased in the brains of mice treated with RCM-Ex. These results suggest that RCM-Ex may be an effective agent for the prevention of the memory impairment induced by cholinergic dysfunction.

본 논문은 가상환경 속에서 사용되는 다감각(시각, 청각, 후각, 촉각)요소가 현실감에 끼치는 영향력을 평가한다. 이번 실험에 80명의 피실험자가 참여하였으며, 여러 감각 요소들을 조합한 가상환경을 경험하게 하여 얻은 실험 데이터를 분석함으로써 각 요소들의 영향도를 평가한다. 주된 평가 요소는 가상 현실 환경 속에서 피실험자가 주관적으로 느끼는 현심감과, 감각 요소들이 피실험자들의 기억력에 미치는 영향도를 객관적으로 측정한 결과를 가지고 분산분석법을 사용하여 검증하여 본다. 이번 실험을 통하여 우리는 이러한 다중 감감 요소들이 단일한 감각요소가 있을 때에 비하여 가상 환경 속에서의 사물에 대한 기억력과 현실감을 증가시킬 수 있다는 결과를 얻는다. 또한 피실험자가 느꼈던 가상환경 속의 현실감과 사물에 대한 기억력에 대하여, 시각적인 요소를 증가시키는 것보다 그 외의 다른 요소(청각, 후각, 촉각)들을 첨가시키는 것이 현실감과 기억력을 배가시키는 요소로써 더 효과적이고 민감하게 반응한다.

This study investigated the effects of treadmill exercise on memory ability, cell proliferation, BDNF, and TrkB in the hippocampus and forebrain cholinergic cells in adolescent rats. Male Sprague-Dawley rats (4 weeks old) were randomly assigned to the following two groups: the sedentary group (n=10) and the exercise group (n=10). Rats in the exercise group were forced to run on a treadmill for 30 min, five times per week for 4 weeks. The latency of the step-through avoidance task was used in order to evaluate memory ability. Hippocampal brain-derived neurotrophic factor (BDNF) and tropomyosin-related kinase B (TrkB) expression were assessed by Western blotting. Hippocampal cell proliferation and forebrain cholinergic cells were assessed by immunohistochemistry. The present study showed that treadmill running during the adolescent period significantly improved memory capability, increased hippocampal cell proliferation, up-regulated hippocampal BDNF and TrkB expression, and enhanced the number of forebrain cholinergic cells. These results suggest that regular exercise during the adolescent period may enhance memory function.

감미료는 감각을 만족시키는 기능을 가지며, 에너지를 공급하는 영양적 감미료와 에너지를 공급하지 않는 비 영양적 감미료로 분류 될 수 있다. 영양적 감미료들은(설탕, 과당 등) 미국 식약청에서는 일반적으로 안전하다고 인식(generally recognized as safe, GRAS) 되고 있다. 그러나 감미료 섭취는 적절한 영양섭취와 건강과 관련하여 아직 많은 우려를 가지고 있다. 첨가당으로부터의 에너지 섭취가 총 에너지 섭취의 25% 이상이면 식사의 질(quality)이 낮아진다. 지난 수 십 년 간, 당 섭취가 행동적인 면에 부정적으로 작용한다는 많은 이론들이 대두되었다. 그러나 포도당은 뇌의 주요 에너지원이다. 포도당의 기억력 향상기능은 모든 연령에서 보고되었으며, 특히 젊은 층보다는 노인에서 더 효과적이었다. 특히 적당량으로 섭취하였을 때 포도당의 섭취는 단어기억, 이야기 기억, 24시간 전에 학습한 정보에 대한 기억, 경계(vigilance)의 향상, 반응시간의 단축, 정신적 계산 능력의 향상, 시뮬레이터 조절에서의 실수감소, 스투르프효과(Stroop effect)의 감소, 지능검사의 향상, 실제사건에 대한 기억력 검사와 웩슬러 척도(Wechsler Scale)에서의 향상과 같은 여러 인지능력 검사에서 좋은 영향을 미친다고 한다. 포도당 용액과 간식의 섭취는 기억력을 개선한다. 아침식사를 거르는 것은 아동들에서 낮은 학습능력을 보인다. 인지능력 변화와 관련 있는 식이는 뇌에 포도당을 공급하는 것과 관련 있다. 과당도 동물실험에서 기억력을 향상시키는 기능이 있다는 것을 보여주고 있다. 본 논문은 당 섭취가 인지능력에 미치는 영향에 대한 과학적인 연구들을 종합하여 정리한 것이다.

This study examined whether Mild Cognitive Impairment (MCI) is related to the reduction of specific memory among linguistic memory and visuospatial memory, and to identify the most predictive index for discriminating MCI from normal elderly. The subjects were analyzed for 189 elderly (103 healthy elderly, 86 MCI). The verbal memory was used by the Seoul Verbal Learning Test. visuospatial memory was measured using the Rey Complex Figure Test. As a result of multiple logistic regression, verbal memory and visuospatial memory showed significant predictive performance in discriminating MCI from normal elderly. On the other hand, when all the confounding variables were corrected, including the results of each memory test, the predictive power was significant in distinguishing MCI from normal aging only in the immediate recall of verbal memory, and the predictive power was not significant in the immediate recall of visuospatial memory. This result suggests that delayed recall of visuospatial memory and immediate recall of verbal memory are the best combinations to discriminate memory ability of MCI.

The aim of this study was to investigate the influence of rosemary oil inhalation on memory, attention and autonomic nervous system according to the concentration difference in the aged. The research design was non-equivalent control group non-synchronized design. Participants were 89 individuals aged 65 or older who live in the community. Participants inhaled almond carrier oil(control group), 10%(experimental group A) and 100%(experimental group B) rosemary oil. Memory, attention, and autonomic nervous system responses were measured. Data were analyzed by SPSS win 24.0. The differences of the group and time were analyzed through repeated measure ANOVA. There were no significant differences in immediate recall (F=.42, p =.656), delayed recall (F=.45, p=.639), recognition (F=1.45, p=.242), digit span-forward (F=1.53, p=.223), digit span-backward (F=.46, p=.636), activities of sympathetic nerve system (LF)(F=.19, p=.828), activities of parasympathetic nerve system (HF)(F=.37, p=.694), LH/HF(F=1.39, p=.256), systolic blood pressure (F=.37, p=.694), diastolic blood pressure (F=1.25, p=.291). The inhalation of 10% and 100% rosemary oil for five minutes showed no significant effects on memory, attention and automatic nervous system in the aged.
