  • The purpose of this research is to find the effect of the lesson using open-inquiry report Lubric on open-inquiry standard and science process skill; to find the change of cognition on open-inquiry for elementary school 5th grade students. Two classes (elementary school 5th grade) were selected which located in a small and medium-sized city for this research and they were separated as an experimental group and a comparative group. Open-inquiry lesson was done by referring teaching method which introduced through the curriculum. The procedure was understanding about open-inquiry, making open-inquiry subject, planning, and performing inquiry, mid-term, performing inquiry, making a report, presentation, and evaluation. Open-inquiry report Lubric which developed by Sook-Kyung Kim et al. (2010) was provided to the experimental group. Comparative group was instructed by using open-inquiry report which introduced to the elementary school 5th grade science text book. Interview paper was developed in order to check out the effect of the research by using a test paper of science process skill. The following could be found out through the research. After open-inquiry lesson, 10 open-inquiry reports(5 reports from experimental group, 5 reports from comparative group) have been drawn at random as samples from the total 62 sets (30 reports from experimental group, 32 reports from comparative group) and evaluated by a researcher and two elementary school teachers who have master degree. The reliability of the 3 scorers was 0.923 of mean correlation coefficient. And then the researcher evaluated all open-inquiry reports. The average score of open-inquiry report was 66.78 for experimental group, 54.27 for comparative group, respectively. And there was a significant difference at p<0.05 level as a result of the t-test. The experimental group rated high at p<0.05 level according to the analysis of post-science process skill test. According to the result of survey, both experimental group and comparative group had understood open-inquiry activity. It was especially rated high for experimental group on understanding scientific inquiry process, interest and satisfaction in open-inquiry and re-participation rate. By interviewing experimental group, it is recognized that the students utilized Lubric very well through the overall process. Finally, self-evaluation was done during open-inquiry activity and it was reported that the students gained more knowledge about science and changed to positive about science. As a result, the lesson using open-inquiry report Lubric was effective for students to improve writing skill of an open-inquiry report and science process skill and finally changed the cognition to positive about open-inquiry lesson.

  • 이 연구는 중학교 1학년 과학의 '지각의 물질과 변화' 단원을 공부한 중학생들이 학습한 지질개념을 자연환경과 생활주변에 얼마나 연계시켜 인식하고 있는가를 조사하여 학교교육과 생활환경과의 연계성을 논의하고 주변 자연환경의 차이가 개념 이해와 과학적 태도에 얼마나 영향을 주는지 연구하였다. 연구 대상은 전라북도 전주시, 부안군, 진안군 소재 중학교 2학년 학생 330명을 대상으로 조사했다. 광물과 암석의 경우, 학교학습에서 그 표본관찰 등으로 개념은 정립되어 있는 것으로 분석되었으나, 생활주변의 암석을 관심있게 관찰한 학생은 16%에 불과하며 대부분은 관심이 없다. 전라북도 내 소읍지역 부안과 진안지역에는 주변에 특별한 지층과 지질구조를 가진 채석강과 마이산 등이 있어 암석 및 지질구조의 야외관찰 학습에 연계 지도가 용이한 지역이나 전주지역 학생보다 관찰경험이 조금 많을 뿐, 전 지역 학생들 모두 야외관찰 학습을 거의 하지 않고 있다. '지각의 물질과 변화' 단원의 학습 시, 주변의 야외 관찰 학습장을 찾아서 광물과 암석을 채집해 관찰하고 크고 작은 지질구조를 입체적으로 관찰함으로써 학습의 효과를 높이도록 해야 한다.

  • 문화예술상품은 일반 소비재와 달리 소비자의 가치인식에 따라 중요한 소비의 대상이 되기도 하고 그렇지 못할 수도 있는 특별한 상품이다. 물질적 소비재나 서비스 상품은 상품속성이 주는 물질적 및 비물질적 혜택을 상정하여 상품을 개발하고 그에 따른 마케팅전략을 수립하는 것이 효과적일 수 있다. 그러나 문화예술상품 소비는 소비자의 경험과 교육 등에 의해 형성된 문화예술에 대한 가치인식에 따라 소비추구혜택이 달라질 수 있고, 가치인식과 추구혜택은 문화예술상품의 속성을 선택하는 기준에 영향을 미칠 수 있을 것이다. 본 연구는 '문화예술상품에 대한 가치인식과 추구혜택에 관한 질적 연구'의 후속연구로서 질적 연구에서 나타난 개념구조를 바탕으로 문화예술상품에 대한 소비자의 가치인식 및 추구혜택과 상품속성의 하위차원을 규명하고, 수단-목적 사슬이론을 역으로 적용하여 문화예술상품에 대한 소비자의 가치인식이 추구혜택과 상품속성에 미치는 영향을 규명하고자 하였다. 그리하여 문화예술상품 생산 및 문화예술 정책기관과 문화예술을 활용하는 기업의 문화마케팅의 효율성을 제고하기 위한 실무적 시사점을 제시하고자 실시되었다. 10대 이상 50대 남녀 662명을 대상으로 자료를 수집하고 요인분석과 경로분석을 실시하였다. 예술상품에 대한 소비자의 가치인식과 추구혜택의 하위차원은 질적 연구 결과와 유사하게 나타났으며, 가치인식은 대부분 추구혜택을 매개로 하여 상품속성에 영향을 미치는 것으로 나타나 질적 연구결과와 마찬가지로 수단-목적사슬을 역방향으로 적용하는 것이 타당함을 입증하였다. 즉, 문화예술상품에 대한 소비자의 가치인식이 실제적 편익으로 구체화되고, 소비자는 이러한 추구혜택에 따라 상품속성의 중요도를 고려하여 구매의사를 결정하는 것으로 볼 수 있다. 본 연구는 문화예술상품에 대한 소비자의 가치인식을 긍정적으로 형성·강화시키는 것이 가장 중요한 소비 촉진 요인임을 입증하였으며, 문화예술상품 생산기관에서 소비자 중심의 상품개발과 기업의 효율적인 문화예술마케팅 전략을 개발하기 위한 소비자 정보와 실무적 시사점을 제시하였다. 또한 본 연구 결과는 국민의 삶의 질을 향상시키고자 하는 국가기관의 정책 수립을 위한 유용한 정보로 활용될 수 있을 것이다.

  • Objectives The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects. Methods Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups. Results In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI). Conclusions The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.

  • Residential architecture was a lot more changed due to adopting modern residential type since 1960s. But people in farm houses are still living in a space of their past life causing a discrepancy. For this reason, the paper will identify the changed use for farm houses focusing on their plane views, and reason for the changed use as well. The result of this paper is expected to play a role for practical data to reasonably change and re-model farm houses located in back of cities such as Hyunpoong area. Targeted area for this paper, in order to survey change in residential environment due to industrialization and modernization, has narrowed down to 42 farm houses which are located Yuga-Myun, Hyunpoong-Gun, Dalsung-Gun where tradition and modern characteristics are harmonized being built before 1960s Researching relied on both documentary records and survey on the site, and survey on documentary records was performed in a way that preceding research for changed use of residential area was to be compared with people's farm houses in Kyeongsang-Do area, and survey on the site was carried out by photographing and land surveying and interview and analysis for them, and finally we acquired the result by analyzing use of interior for houses and plane view and relations between culture and social environment. From the result of this paper, there was a trend that farm houses had been improved function of a specific space by enlarging space and enlarged construction for inner rooms. And among spaces, kitchen and bath room was mostly enlarged its left side, and inner room had mostly enlarged its rear side, and kitchen was frequently enlarged in its side space. These kinds of variation in space is believed to be result of change of life style and house facilities

  • Purpose: The objective of this study was to offer clinical primary data that it's aims to examine effects of transcranial direct current stimulation (tDCS) on cognitive function and biochemical change of rat with alzheimer's disease(AD) induced by injecting scopolamine. Methods: Subjects were instructed cognitive dysfunction model, rat of Sprague-Dawley system was injected with scopolamine and each experimental group was classified into three; group I (n=16) is non-treatment groups; group II (n=16) is applied with the tacrine; group III (n=16) is applied with the tDCS. The ziggurat task test was conducted to observe behavioral changes and cognitive function ability and 7, 14, 21, 28 days after the model. Acetylcholine Esterase (Ach E) activity was examined for biochemical assessment of which the results are followed. Results: Participants showed as to behavioral change, tacrine application group was the most significantly responded, following tDCS application group. As to biochemical change, same as above, tacrine application group was the most significantly responded, following tDCS application group. Conclusion: From these results, confirm that tDCS application to rat with alzheimer's disease leads to positive effects on behavioral, cognitive function changes, and biochemical changes, lasting for certain period of time. This study, in particular, tDCS, which can change excitability of brain cells non-invasively, could provide basic data that is useful as a new treatment way for the patients with cognitive dysfunction.

  • Purpose: This purpose of this study was to investigate the effects of initial cognitive status on the recovery of functional status in patients with subacute stroke. Methods: The participants were 111 patients with subacute stroke, divided into two groups: mini-mental state examination (MMSE) <20 (n=49) group and MMSE ≥20 (n=62) group. Clinical evaluation scores were collected before and after rehabilitation. The repeated measurements ANOVA was used to confirm the changes in functional status before and after intervention in the two groups. Changes in functional status within the group were examined through a paired test. A Pearson correlation coefficient analysis was performed to identify the correlation between MMSE change amount and functional status score. Results: In each of the two groups, according to the initial cognitive status, the clinical evaluation score increased statistically significantly, but there was no difference between the two groups in the degree of significant increase. When examining the correlation between the MMSE change amount, according to the initial cognitive state and the functional state score change amount, it was found, only in the group with MMSE <20, that the larger the change in the MMSE score, the greater the functional state change of Berg balance scale, Rivermead Mobility Index, and motor assessment scale. This did not apply to the group with MMSE ≥20. Conclusion: Initial cognitive status should be considered when setting the patient's goal, and considering cognitive improvement when constructing a rehabilitation program is thought to have a positive effect on rehabilitation services.

  • Space and figure are formed not by themselves but by the existence of light. It is important that plays a role as an intermediary of cognition which enables the formation of space and figure through Human's recognition in the process of design. Human perceive space and identity every basic form by the contrast of light and dark. The existence of light is very inclusive concept in the space, so space and form are completed by light. The change of based on time, place, and its amount acts as an important element Which can change the form of Space. In Space light doesn't work simply as light itself, but have a very close relation with Space, Form, Structure, Material, Color elements, Space is limited by physical form but human perceive space relatively by many other conditions, So same space can be experienced differently by the characters of light. Human can recognized and observe an object in the space as he processes information collected through light. In this process light make it possible for human to see the shape in space. therefore, the shape of space can get meanings when light exists. the space recognized by light is the mean that activates human activates in space.

  • Nowadays, the public as well as science educators pays much attention to the fourth industrial revolution and wonders what will happen to the societies in the future. Thus, this study aimed at predicting the education environment which will be brought from the fourth industrial revolution, and suggesting the solutions or tasks to be investigated in science education. Through the literature review, this study categorized the major changes of future society into a wild fluctuation of job market, the shift from possession-based economy to sharing economy, post-urbanized and distributed system, and the crisis of dehumanization. According to the four major changes, this study predicted the future environment that will occur to the educational system. First, the students should the competences necessary for the future and the school curriculum will be changed in terms of width and depth. Second, sharing economy may bring about the open platform similar to MOOC (Massive Open Online Course) or TED. Third, the manifestation of artificial intelligence in education will enable the individual and paced learning, and thanks to the change, the concept of distributed cognition will be more focused in education research. Fourth, the collaborative learning and character education should be more stressed to resist the dehumanization. This study suggests relevant tasks and issues that should be tackled for the successful change in primary and secondary schools.
