A reduced particle-unscented Kalman filter estimation method, along with a splice-equivalent circuit model, is proposed for the state-of-charge estimation of an aeronautical lithium-ion battery pack. The linearization treatment is not required in this method and only a few sigma data points are used, which reduce the computational requirement of state-of-charge estimation. This method also improves the estimation covariance properties by introducing the equilibrium parameter state of balance for the aeronautical lithium-ion battery pack. In addition, the estimation performance is validated by the experimental results. The proposed state-of-charge estimation method exhibits a root-mean-square error value of 1.42% and a mean error value of 4.96%. This method is insensitive to the parameter variation of the splice-equivalent circuit model, and thus, it plays an important role in the popularization and application of the aeronautical lithium-ion battery pack.

Special educations for gifted students have not been given enough attention in Japan with a little exception. Indeed, such educations were sometimes despised in Japan by teachers and parents as well as by boards of education, because one of the features of postwar education system in Japan was an excessive egalitarianism. The other is cramming of knowledge in school education, which is necessary for high school graduates to pass entrance examinations for famous universities such as University of Tokyo, or Kyoko University. However, in 1997, some trials of special educations for gifted students started. The Ministry of Education, Sports, Culture, Science and Technology admitted 'skipping a year to enter universities.' In this paper, the following three topics would be discussed. 1. Enrollment of high school students aged 17 into Chiba University. 2. Summer seminars conducted by Japan Mathematics Foundation of Olympiad. 3. Super Science High School Program funded by the Ministry of Education.

구조형식별로 구조물의 안정성 확보를 위해 KBC2009에 새로이 도입된 높이제한에 따라, 내진설계범주D에 해당되는 60 m 이상의 RC 구조물을 계획할 경우 특수전단벽을 의무적으로 사용해야 한다. 그러나 특수전단벽의 엄격한 횡보강 배근상세는 시공성 및 경제성에 부정적 영향을 미칠 것으로 예상된다. 그래서 이 연구에서는 현 규준에 따른 특수전단벽보다 완화된 배근 상세를 갖는 특수전단벽을 제안하고, 특수전단벽과의 성능 비교를 위하여 각각 두 개의 실험체를 제작하고 횡방향 반복 하중실험을 실시하였다. 또한 그 실험 결과를 반영한 보통전단벽, 특수전단벽, 완화된 특수전단벽 구조시스템의 해석모델을 설계하여 FEMA P695에 따른 방법론으로 내진성능평가를 실시하였다.

The purpose of this study was to investigate dietitians or nutrition teachers' perception of sugar reduction and usage of sugars in school meal service. A survey was conducted for dietitians or nutrition teachers at elementary, middle, and high schools in Gyeonggi and Incheon. Survey data were analyzed according to the experience period and school types of dietitians or nutrition teachers. The numbers of subjects according to work experience period were 134 (44.2%) for <5 years, 68 (22.4%) for ${\geq}5$ and <10 years, and 101 (33.3%) for ${\geq}10years$. Among the subjects, 168 (55.4%) were nutrition teachers at kindergarten/elementary schools, and 135 (44.6%) were at middle/high/special schools. Perceptions of sugar reduction programs were higher in kindergarten/elementary schools than in middle/high/special schools. The perception of added sugar use increased with more work experience, and interest in sugar reduction was higher in kindergarten/elementary schools than in middle/high/special schools. Practice for added sugar reduction increased with more work experience, and the most common method for reducing sugar was use of natural sugars. The main reason for not reducing added sugars in school meals was due to preference. Nutritional education for students increased with more work experience and was higher in kindergarten/elementary schools than in middle/high/special schools. The major nutritional education methods were using school homepage (37.4%), sending family letters (37.4%), and using principle's discretion time (18.4%). Organic sugar and rice taffy were used more at kindergarten/elementary schools, and white sugar, brown sugar, and white syrup were used more at middle/high/special schools. The most common menu using added sugars was stir-fried dishes (stir-fried pork, chicken, and vegetables).

This study investigates the mechanism of MnS precipitation on $Al_2O_3-SiO_2$ inclusions during the solidification of non-oriented silicon steel, especially the influence of the phase structures and sizes of the oxides on the MnS precipitation, by scanning electron microscopy and transmission electron microscopy coupled with energy dispersive spectrometry. The investigation results show that MnS tends to nucleate on submicron-sized $Al_2O_3-SiO_2$ inclusions formed by interdendritic segregation and that it covers the oxides completely. In addition, MnS can precipitate on micron-sized oxides and its precipitation behavior is governed by the phase structure of the oxides. The MnS embryo formed in a MnO-containing oxide can act as a substrate for MnS precipitation, thus permitting further growth via diffusion of solute atoms from the matrix. MnS also precipitates in a MnO-free oxide by the heterogeneous nucleation mechanism. Furthermore, MnS is less prone to precipitation in the $Al_2O_3$-rich regions of the $Al_2O_3-SiO_2$ inclusions; this can be explained by the high lattice disregistry between MnS and $Al_2O_3$.
