  • In this study, 17 formative assessments using cartoon were developed for studying 'genetics and evolution' chapter in textbook of third grade of junior high school. And those were applied to 73 students in experimental group and 78 students in control group. We investigated if there was positive effect on students' perception, attitude about assessment and scholastic achievement. As a result, we could find the formative assessments using cartoon were effective to change students' negative perception and attitude to positive one. Especially, those were effective to make students to understand usefulness of assessment (p<.05), and to decrease a feeling of uneasiness about assessment (p<.01). Also, we could find the developed formative assessments using cartoon had more positive effect on raising scholastic achievement than formative assessment using descriptive passage (p<.05). It was considered that this was because the abstract concepts of 'genetics and evolution' chapter were described in pictures, so contexts of textbook and assessment questions became easier to understand. So, we could conclude that formative assessment using cartoon contributed to increase students' understanding of contexts of textbook and to increase their interests about study. And if this assessment method is applied to class actively, students' feeling of uneasiness about assessment can be easily overcome and it can also give them positive perception about assessment.

  • The architectural space is the involuntary place where man lives and experiences, and as a 3 dimensional space through the continuous experience with the concept of 4th dimension of time, it provides the observers with the dramatic space imagery These kinds of space experiences are experienced mentally and perceptively through the physical elements of inner and outer space of the architectural buildings, and this space imagery is created here by all the space composing elemensts of the building. These space experiences are caused by the changing processes of the space characteristics, and the observers perceive the changes in space characteristics. The present building is going with Eco-Architecture. When 2008 sees the building,,Eco-Architecture design which hits appears. There is a possibility of seeing 16 kind types from that place. And From here examined the spatiality which is expressed. These changing processes of inner and outer space, space versus space, and unit space, which are perceived by the observer. It's way to help in architectural design and wishes.

  • The probability of visual perception occurrence varies in case the expectation of using each unit space of which the whole space consists because the size of space subject to analysis is very large or the organization is complicated in the analysis of spatial visual configuration. Therefore, it is necessary to compensate space analysis and index measurement by applying weight to the point of view for the probability of experiencing space. This study proposed a method of analyzing visibility ratio by applying the integration of space syntax theory as weight, and grasped the effect in comparison with the visibility ratio when weight was not applied.

  • Companies need to secure strong methods of new product development in a rapidly changing competitive environment. They overly focusing on the perception of consumers can not lead radical changes. They need to generate sufficient creative ideas in the early stages of new product development to make radical change. The purpose of this study is to examine the effect of a creative method on the generation of creative ideas. An enhanced creativity method was designed considering existing methodology and cognitive elements. This study specifically focused on team rather than individual level creativity. This arrangement reflects the fact that companies in practice rely on team unit in NPD process. The contribution of the study is two fold : enhancing existing methodology, and testing the effect of conceptual distance on making of creative ideas. The experimental results showed that appropriate conceptual distance help to make best creative output and that ABIS attribute is proved to be more effective than traditional association.

  • Electroencephalography (EEG) recordings taken during the perception of music tempo contain information that estimates the tempo of a music piece. If information about this tempo stimulus in EEG recordings can be extracted and classified, it can be effectively used to construct a music-based brain-computer interface. This study proposes a novel convolutional recurrent attention model (CRAM) to extract and classify features corresponding to tempo stimuli from EEG recordings of listeners who listened with concentration to the tempo of musics. The proposed CRAM is composed of six modules, namely, network inputs, two-dimensional convolutional bidirectional gated recurrent unit-based sample encoder, sample-level intuitive attention, segment encoder, segment-level intuitive attention, and softmax layer, to effectively model spatiotemporal features and improve the classification accuracy of tempo stimuli. To evaluate the proposed method's performance, we conducted experiments on two benchmark datasets. The proposed method achieves promising results, outperforming recent methods.

  • The purpose of multiple alarm processing is to give the operator the correct information and perception of the malfunction present in the plant. In this thesis, an APS(Alarm Processing System) is studied for fossil power plants. This APS is based on a cause-consequence trees in the knowledge representation aspect for alarm and plant and adapts alarm filtering methods using fired time information in the decision aspect. Through the cause-consequence trees and filtering methods, the Alarm Processing System finds the cause alarm among the fired multiple alarms and calculates the cause degree which represents the possibility of a fault occurring in the instruments of the plant with the information of fired alarm. The knowledge base is built via interviews and questionaries with the expert operators on the Seoul power plant unit 4. Finally, the validity of the studied APS is shown via simulations.

  • International Roughness Index (IRI) has been widely used by state DOTs to quantify pavement smoothness. When pavement condition falls below certain IRI thresholds, corresponding pavement maintenance treatments should be considered for application. Selection of appropriate IRI thresholds is essential to tactical allocation of limited resources to improve the conditions of states' roadway systems. This selection process is often challenging, however, because IRI thresholds are largely determined by Perceived Ride Quality (PRQ), and PRQ differs in each state. In this paper, a framework is proposed to address this problem. Passenger raters will be randomly selected from predetermined geographic locations, and their PRQ ratings collected. Taking this perceived ride data, along with other data collected, a statistical analysis will be conducted to establish the relationship between measured IRI values and PRQ. Appropriate IRI thresholds will then be determined. Once this framework is implemented, state DOTs could make informative maintenance decisions, which are expected to greatly enhance the public perception of pavement conditions in today's challenging economy.

  • Background: Liver fluke infection with Opisthorchis viverrini and its associated cholangiocarcinoma constitute a serious problem in Thailand. Healthy behavior can decrease infection, therefore, the investigation of knowledge, attitude, and practice is need required in high risk areas. Objective: This study aimed to investigate the behavior and perceptions regarding liver fluke. Materials and Methods: A cross-sectional descriptive study was conducted in Chum Phuang district of Nakhon Ratchasima province, Thailand during July to November 2015. A total 80 participants who had screened with verbal screening test, stool examination, and ultrasonography, were purposive selected and completed a pre-designed questionnaire (Kruder-Richardon-20=0.80, Cronbach's alpha coefficient=0.82 and 0.79). T-test, ANOVA, and Pearson correlation test were used for analyzed data. Results: The results reveal that O. viverrini infection was 1.25%, and 3 patients had a dilated bile ducts. The participants had a high knowledge, attitude, and practice regarding liver fluke. The education, occupation, and income, were statistical significant to attitude regarding liver fluke. Nurses and television were the main sources of information regarding liver fluke, with statistical significance(p-value <0.05). Knowledge was significantly associated with attitude and practice (p-value<0.05). Conclusions: Participants had good behavior regarding liver fluke. Improvement of knowledge and attitude is influenced to practical change regarding this carcinogenic fluke. In addition, nurse and television are the main information resources for key success in increasing people perception for disease prevention and control in this area.
