We present the influence of a midterm integration which supports making relations among many varied learning materials from learners' own viewpoints. We designed a curriculum for the learners integrating sets of similar learning materials at the midterm before integrating broader learning materials in the final results. A concept mapping system called "ReCoNote" helped the learners externalize their thinking. The result is that learners from the 2007 class were more successful in deepening integration of their knowledge at the midterm than learners from the 2006 class. And the learners in 2007 made more relations among the learning materials to their final concept maps than in 2006. In the activity of making relations, the learners in 2007 used their own common concepts or keywords which were made at the midterm when they relate the learning materials. These results suggest that supporting constructing the learners' own integrated knowledge helped them relate many varied learning materials from their own viewpoints. © 2011 IEEE.

New teachers who are shocked by real-world classroom situations - such as rules of the local school, human relationships in a shielded environment, and the reality of teaching children - Tend to leave the workforce within a few years, and it has become necessary to educate student teachers in the universities with a focus on adaptive professional socialization of teachers (Zeichner & Gore 1990) to overcome this problem. We have provided a weblog community where pre-service teachers can have a dialogue based on their report of experiences during their practice teaching. However, in order to promote the professional socialization of teachers, we have designed a new weblog community where experienced teachers can participate. Through comparative analysis, we have pursued the effectiveness of this change in design. In this study, we referred to Hong (2010) and categorized their diaries and comments within the weblog community into nine factors, and analyzed the features of their communication. We revised the design of the pre-teaching from the year 2010, and altered the lesson design of the pre-teaching for the year 2012 so that pre-service teachers could exchange their opinions focusing more on the ways of schools and teachers. The class design was changed so that experienced teachers provided hints during pre-teaching to motivate pre-service teachers to think about the issues, and the pre-service teachers were made to take the initiative in using the weblog. From the results, we found that the number of entries of diaries and comments into the weblog community differed between the years 2010 and 2012. Moreover, it became relevant that the ratio of the diary entries about "commitment towards work," "value and standpoint as teachers" and the like increased.

The purpose of this paper is to develop a ceiling hanging mobile robot for factories, offices and living spaces where human and robots can share spaces cooperatively. Based on an analysis of related work, we select two promising candidates of ceiling attachment method; a permanent magnet method and a mechanical constraint method. We combine these two ceiling attachment methods with practical locomotion methods, and realize two ceiling hanging mobile robots. Two different robots are designed and implemented based on our selected approaches. We evaluated the basic performances of those two robots in experiments. Difficulties in their design and implementation processes of the two robots are described, and technical insights are summarized based on the comparison of difficulties, safety, performance and cost. Discussions reveal that the two robots have quite different characteristics. In conclusion, two different application areas are proposed for the two robots with different ceiling attachment methods. Although there are large numbers of reports on wall climbing or ceiling hanging mobile robots, this paper is the first work, to our knowledge, to compare qualitatively and quantitatively the performances of multiple robots through development of real prototypes.

Hand gestures can potentially express rich information for communication between humans or between a human and a machine. However, existing hand-shape recognition methods have several problems in utilizing hand gestures in home automation. We have focused on 'wrist contour', and have developed a wrist-watch-type device that measures wrist contour using photo reflector arrays. In this paper, we address three challenges: improvement of hand-shape recognition performance, making clear the effect of personal difference, and identifying problems caused by pronation angle changes. To address the former two challenges, we have collected wrist contour data from 28 subjects and conducted two experiments. For the first challenge, three different feature types are compared. The results extract several important contour statistics and the classification rate is also improved by introducing multiple subjects' data for training. For the second challenge, we compose a resemblance matrix to evaluate resemblance among subjects. The results indicate that training data selection is important to improve classification performance. To address the third challenge, two inertial measurement units are installed in the device. We have collected wrist contour data in various pronation angles, and specific relationships are found between wrist contour data and pronation angles. © The Author(s) 2014.

The latent rank structure of the General Health Questionnaire (GHQ) was examined and a methodology for "ranking assessment" for use in clinical screening was suggested. Clinical screening is conducted by using dichotomous methods, which is problematic. Recent research has introduced the concept of ranking assessment, which is conducted by dividing clients into ordinal groups according to the Latent Rank Theory (LRT). Participants (N = 949, including 80 neurotic patients) completed the GHQ. They were then divided into four ordinal groups according to LRT. The usual cut-off point of the GHQ (16/17 points) distinguished the third and fourth rank group as the clinical group and the first-rank group as the healthy group. However, the second rank group was classified as neither a healthy or clinical group. These results indicate that the LRT has the potential to facilitate practical and flexible clinical screening.
