To ensure the effective operation of a curriculum, facilities and equipments should be properly supported. Therefore, changes are required for educational facilities in accordance with the curriculum, revised 10 times in total from 1945 to 2011, but it's true that the facility and equipment laws, which are the standards of facility and equipment changes, did not adapt to the changes. After 'the Act on Standards of School Facilities' was repealed, 'the Act on Establishment and Operation of the Schools,' the corresponding law for the purpose of spatial configuration for teaching and learning methods, was enacted in Sept. 1997. This law has been active for 14 years and revised 11 times thereafter. It has also been decided to often revise the curriculum, so the 7th National curriculum has undergone 6 times of minor revisions. Among them, the most recently revised 2009 curriculum is to be applied for elementary school 1st and 2nd grade, middle school 1st grade, and high school 1st grade from the beginning of this year of 2011. Hereupon, the purpose of this study is to research on the revisions of the school facility and equipment standards which can support the curriculum revised in 2009 and thereafter by examining classrooms and facilities as the learning space that can respond to the changes of school functions and systems with curriculum transition, of teaching and learning systems, and of subjects.

이 연구는 학년이 상승하면서 초등학생들의 자연수 계산 오류가 어떤 양상을 띠며 변해 가는지를 알아보고, 이를 통해 효율적인 계산 지도를 위한 시사점을 도출하고자 시도되었다. 이를 위해 수도권의 한 초등학교 3, 4, 5, 6학년 580명을 대상으로, 동일한 뺄셈, 곱셈, 나눗셈 검사지를 풀게 하였으며, 미리 설정한 오류유형틀에 입각하여 학생의 오답 반응을 분석하였다. 학생들의 반응을 분석한 결과, 세 계산 영역에서 학년 상승에 따른 계산 수행능력의 향상이 통계적으로 유의미한 수치로 나타났으며, 계산 절차를 처음 배우는 시점에서 차년도까지의 향상 폭이 가장 큰 것으로 나타났다. 그러나 초등학생들의 계산 오류는 일회 혹은 이회 정도 반복되지만 삼회이상은 잘 반복되지 않는, 체계성이나 고착성이 비교적 낮은 것으로 드러났다. 마지막으로, 이러한 내용을 바탕으로 계산 지도의 효율성을 높이기 위한 지도 전략을 제안하였다.

This study aimed to analyze about the perception in obesity and body somatotype of university students in Korea and in China. This study provides the basic data of nutrition education for university student healthy weight program in China. The subjects were selected 240 university students of Korea and China. Two types of qualitative and quantitative questionnaires were used to analyze the attitude and body somatotype of subjects. The results of this study were as follows: The average BMI of Korean and Chinese male students was 22.3 and 22.5, respectively while the average BMI of Korean and Chinese female students was 19.8 and 19.7, respectively. In the past three years, the weight gain of Chinese students was higher than that of Korean students. Chinese students preferred the overweight body somatotype more compared to the Korean students. The overweight and obese students had more obvious insufficiency in body somatotype perception. The overweight and obese students had higher tendency to 'eat more meat', 'drink carbonated beverages', 'eat convenience food', 'take fast food' and 'drink alcohol' than the normal and low weight group. The major reasons for Korean students to control weight were 'appearance' and 'self confidence', while the major reasons for Chinese students were 'health' and 'employment'. From the results of associative group analysis (AGA), Chinese students had different semantic value of 'obese' than Korean students. Considering of the food transition status in China, it may be necessary to develop more suitable education programs for weight control for Chinese university students.

Glasses were prepared with compositions of $(13-x)BaO-80B2_O_3-7Li_2O{\cdot}xSm_2O_3$, BBLSx(x=0.5, 0.4, 0.3) by melting the starting materials of boron oxide(99.9%), lithium oxide(99.9%), barium carbon oxide(99.9%), and samarium oxide(99.9%) and then quenching the melt at $1350^{\circ}C$. This led to good-quality BBLSx(x=0.4, 0.3) and poor-quality BBLSx(x=0.5) glasses. The physical and structural properties of the BBLSx glasses were studied by means x-ray diffraction, scanning electron microscopy(SEM), differential scanning calorimetry(DSC), and dielectric spectroscopy. From the x-ray diffraction and SEM results, the quality of the BBLSx glasses significantly depends on the $Sm_2O_3$ concentration. The x-ray diffraction pattern showed that the crystallites in the BBLSx glasses after heat treatment at $700^{\circ}C$ may be $LiBaB_9O_{15}$. From the DSC results, the glass transition temperatures($T_g$), crystallization temperatures($T_c$), and the maximum temperatures of the crystallized($T_p$) BBLSx glasses all changed with the $Sm_2O_3$ concentration. According to the dielectric spectroscopy results, the values of the real dielectric constant and Tan ${\delta}$ of the BBLSx glasses depended on the $Sm_2O_3$ concentration. The values of the real dielectric constant and Tan ${\delta}$ were also shown to depend on the measuring temperature, possibly due to the ion migration in the bulk of the BBLSx glasses.

최근, 플라스틱 남용으로 인해 바이오매스 기반 물질에 대한 연구의 중요성이 증가하고 있는 추세이다. Cellulose acetate butyrate (CAB)는 생분해성의 성질 때문에 재생이 가능하여 잠재성을 가지고 있는 고분자이다. Poly(ethylene-co-isosorbide terephthalate) (PEIT)는 아이소소바이드 모노머로부터 유래된 바이오매스 기반의 고분자이다. 본 연구에서는 다양한 분야에 적용되고 있지만 열안정성이 낮은 CAB에 내열성이 높은 PEIT를 도입하여 용액 블렌딩 방법을 통해 CAB/PEIT 블렌드를 제조하였다. 블렌드의 상용성을 판단하기 위해 모폴로지와 유리전이온도의 거동을 FE-SEM, DMA를 사용하여 분석하였다. TGA 결과는 CAB/PEIT 75/50, 50/50 조성에서 향상된 열적 안정성을 나타내었으며 XRD에서 새로운 결정 구조는 관찰되지 않았다. 결과적으로 CAB/PEIT solution blends는 모든 조성에서 좋은 상용성을 가짐을 확인하였다.

소수의 개념적 측면에 대한 학생들의 이해 부족 현상이 목격되는바 본 연구는 학생들이 소수 개념의 본질을 바르게 이해하도록 돕고자, 소수 개념 발전 역사를 조망하고 교과서의 개념 도입 방법을 분석하였다. 고대 그리스에서 소수는 곱셈 원자였다. 당시 단위는 수가 아니었지만, 소수 표기 개발로 단위가 수로 통합되면서 1의 소수성이 문제시 되었다. 소인수분해의 유일성을 근거로 1이 소수에서 배제되었으며, 이후 발전을 거듭하여 prime 개념과 irreducible 개념이 자리 잡게 되었다. 소수 개념 발전의 역사는 소수가 곧 곱셈 원자라는 사실이 개념의 본질임을 명백히 드러낸다. 교과서 분석 결과, 교과서는 소수 개념을 결정론적 시각 혹은 게임으로 도입하여 개념 본질을 드러내지 못하는 문제, 개념 도입 후 분석적 개념 정의로 급진적 전개가 이루어지는 문제 등이 있었다. 분석 결과에 기초하여 소수의 개념적 면에 주목하도록 돕는 것과 관련하여 몇 가지 교수학적 시사점을 제공하였다.

This research is to analyze the public cases of information facilities in terms of central circulations in multi level volumes such as atrium or court which provide visual intervention between different spaces and physical connections such as bridges. Hunt Library design balances the understood pre-existing needs with the University's emerging needs to create a forward-thinking learning environment. While clearly a contemporary structure within a traditional context of the NCSU campus, the Hunt Library provides a positive platform for influencing its surroundings. Both technical and programmatic innovations are celebrated as part of the learning experience and provide a versatile and stimulating environment for students. Public library as open spaces connecting to an interactive social domain over communities can provide variety of learning environments, or technology based labs. There are many cases of the public information spaces with dynamic networks where participants can play their roles in physical space as well as in the intellectual stimulation. In the research, new public projects provide typologies of information spaces with user oriented media. The research is to address a creative transition between the reading space and the experimental links of the integration of state-of-the-art technology is highly visible in the building's design. The user-friendly browsing system that replaces the traditional browsing with the virtual shelves classified and archived by their form, is to reduce the storage space of the public library and it is to allow more space for collaborative learning. In addition to the intelligent robot of information storages, innovative features is the large-scale visualization space that supports team experiments to carry out collaborative online works and therefore the public library's various programs is to provide visitors with more efficient participatory environment.

Objectives: Children with attention-deficit/hyperactivity disorder (ADHD) tend to be noisy and violate rules with their disruptive behaviors, resulting in greater difficulties with off-task behaviors and being at risk for social refusal. The visual activity schedule (VAS) intervention program is a frequently used method to teach multiple skills involving on-task, use of schedules, transition behaviors, social initiation, independent play skills, classroom skills, and academic skills. The current systematic review aimed to examine the efficacy of using VAS intervention in reducing problem behaviors in children with ADHD between 5 and 12 years of age. Methods: Systematic searches were conducted using two electronic databases (PubMed and Scopus) to identify relevant studies published in English between 2010 and 2020. Four studies met the inclusion criteria: two studies examined the effect of schedule-based tasks and the use of an iPad on classroom skills, while the other two examined randomized clinical trials (RCTs) of psychosocial treatment for ADHD inattentive type and a cross-sectional study examined the impact of the group size on task behavior and work productivity in children with ADHD. Results: The findings indicate that the interventions used in all four studies could lead to increased satisfaction among participants and parents, as well as a reduction in problem behavior. In terms of the research indicators, the RCT had low quality, while the others were of high quality. Conclusion: A larger number of studies and the ADHD clinical population would help to increase the generalizability of future reviews of treatments in this context.

The MobileNetV3 is specially designed for mobile devices with limited memory and computing power. To reduce the network parameters and improve the network inference speed, a new lightweight network is proposed based on MobileNetV3. Firstly, to reduce the computation of residual blocks, a partial residual structure is designed by dividing the input feature maps into two parts. The designed partial residual structure is used to replace the residual block in MobileNetV3. Secondly, a dual-path feature extraction structure is designed to further reduce the computation of MobileNetV3. Different convolution kernel sizes are used in the two paths to extract feature maps with different sizes. Besides, a transition layer is also designed for fusing features to reduce the influence of the new structure on accuracy. The CIFAR-100 dataset and Image Net dataset are used to test the performance of the proposed partial residual structure. The ResNet based on the proposed partial residual structure has smaller parameters and FLOPs than the original ResNet. The performance of improved MobileNetV3 is tested on CIFAR-10, CIFAR-100 and ImageNet image classification task dataset. Comparing MobileNetV3, GhostNet and MobileNetV2, the improved MobileNetV3 has smaller parameters and FLOPs. Besides, the improved MobileNetV3 is also tested on CPU and Raspberry Pi. It is faster than other networks
