The theme of this study is holistic healing environment of children's library and it was researched on the basis of anthroposophy theory of Rudolf Steiner. According to Steiner's theory, human being consists of body, spirit, and soul. Especially, children are sensitive ones, and through synthetic function of 12 kinds of senses, they can be holistically healed (healing of body, spirit, and soul). As the sense independently functions or it is a element that cannot be described, it needs spatial plan to support synthetic function of it. We classified the healing space's meaning of children library by motion (including art and music), reading, & landscape healing activities and analyzed spatial characteristic to support each activity.

Nowadays, railroads are considered the most efficient form of mass transportation. Furthermore, it is necessary that railroads be paired with state-of-the-art safety equipment. Unfortunately, it is impossible to prevent 100% of accidents that may be caused by system or human errors. In order to prevent future accidents, RAMS activity and Functional Safety Certification are required for new systems that are under development. In this paper we evaluate the necessity of the application of RAMS and the performance of RAMS in the system development process. We also explore the Safety Evaluation Procedure required for RAMS certification.

The world at the end of the $20^{th}$ Century has become "blue" Indeed, this past decade has witnessed a "blue rush" towards the development of violet-blue-green light emitting diodes (LEDs) and laser diodes (LDs) based on wide bandgap III-Nitride semiconductors. And the hard work has culminated with, first, the demonstration of commercial high brightness blue and green LEDs and of commercial violet LDs, at the very end of this decade. Thanks to their extraordinary properties, these semiconductor materials have generated a plethora of activity in semiconductor science and technology. Novel approaches are explored daily to improve the current optoelectronics state-of-the-art. Such improvements will extend the usage and the efficiency of new light sources (e.g. white LEDs), support the rising information technology age (e.g. high density optical data storage), and enhance the environmental awareness capabilities of humans (ultraviolet and visible photon detectors and sensors). Such opportunities and many others will be reviewed in this presentation.

In response to a growing trend toward downward escalation of public school curriculum, the present study surveyed so-called extracurricular activities in kindergartens and analyzed teacher's perception of these activities. Questionnaires were mailed to 1300 private kindergartens and 1116 responses were received. Major findings were that over 89% of the respondents reported doing extracurricular activities in their kindergartens, mostly using 3-4 different kinds of special activities. The 3 most highly ranked lessons in order of frequency were English, art and physical activity. Whole group time was most often used for extracurricular activities. Kindergarten teachers were concerned with the qualifications of teachers for these activities. Teachers of these extra activities usually have no specialized training or supervised experience working with 3-through 5-year-old children.

Ginsenosides have been regarded as the principal components responsible for the pharmacological and biological activities of ginseng. The transformation of ginsenosides with live lactic acid bacteria transformed ginsenosides Rb2 and Rc into Rd, but the reactions were slow. When the crude enzymes obtained from several lactic acid bacteria were used for transformation, those from Bifidobacterium sp. Int57 exhibited the most potent transforming activity of ginsenosides to compound K. In comparison, a relatively higher level of Rh2 was produced by the enzymes from Lactobacillus delbrueckii and Leuconostoc mesenteroides. These results suggest that it is feasible to develop a specific bioconversion process to obtain specific ginsenosides using the appropriate combination of ginsenoside substrates and specific microbial enzymes.

Human actions can be recognized from depth sequences. In the proposed algorithm, we initially construct depth, motion maps (DMM) by projecting each depth frame onto three orthogonal Cartesian planes and add the motion energy for each view. The body part of the action (BPoA) is calculated by using bounding box with an optimal window size based on maximum spatial and temporal changes for each DMM. Furthermore, feature vector is constructed by using BPoA for each human action view. In this paper, we employed an ensemble based learning approach called Rotation Forest to recognize different actions Experimental results show that proposed method has significantly outperforms the state-of-the-art methods on Microsoft Research (MSR) Action 3D and MSR DailyActivity3D dataset.

This paper reviews the Insaenggeukjang's history and Insaenggeukjang's play. This paper has been written with a purpose to understand and to examine the members(actors and actresses), the structure, the plays, the performing works, the change process, and the meaning of Insaenggeukjang(life theater) and junggangeug(middle-theater) in 1930s. Insaenggeukjang is Korean theater for the drama in the second half of 1930s. In particular, Insaenggeukjang is a theatrical troupe that led Korean theatrical troupes in 1937 to 1938. This paper intend to examine Insaenggeukjang's history, activity, feature and works. I study Insaenggeukjang and performing works contained in the newspapers and the magazines in 1920-30s, and conference papers and theater-art books published recently.

Visual tracking is a challenging task that needs learning an effective model to handle the changes of target appearance caused by factors such as pose variation, illumination change, occlusion and motion blur. In this paper, a novel tracking algorithm based on weighted local sub-space reconstruction error is presented. First, accounting for the appearance changes in the tracking process, a generative weight calculation method based on structural reconstruction error is proposed. Furthermore, a template update scheme of occlusion-aware is introduced, in which we reconstruct a new template instead of simply exploiting the best observation for template update. The effectiveness and feasibility of the proposed algorithm are verified by comparing it with some state-of-the-art algorithms quantitatively and qualitatively.

This study provides a comprehensive evaluation of general characteristics of sized silk fabrics for the painting purpose. Two particular types of silk fabrics used for painting background were compared: a recreation of historical material and a mass produced material of present day. The sizing process made the surface characteristics of the silk fabrics more suitable for painting. The dyeing properties of the fabrics were related to the surface area of the fabrics, and had no significant effect on their mechanical properties. The antibacterial activity of the tannin-based natural dyestuffs were maintained after the sizing. The performance assessment by the KES-FB system showed that the fabrics are more prone to deteriorate after the sizing because the glue layer receives the most of the physical stresses.
