This study analyzed the characteristics of diverse information adoption pathways per pathway of information composition category including 'information perception', 'information assessment', and 'information adoption' and examined information adoption characteristics per pattern. In addition, differences among agricultural researchers and farmers per information adoption stage were analyzed. According to these analyses, as for farmers' information adoption pathways, while the formal extension type and the situational reaction diffusion type used the direct pathway of 'information perception ${\rightarrow}$ information adoption,'the agriculturist connection type and the systematic approach type did not use the direct pathway of 'information perception ${\rightarrow}$ information adoption' but, instead, adopted information by moving from the 'information perception ${\rightarrow}$ information assessment' pathway to the 'information assessment ${\rightarrow}$ information adoption' pathway, with information assessment as the intermediation. In the case of farmers, information adoption was the highest in comparison with information assessment and information perception in all patterns whereas, in the case of agricultural researchers, the results were exactly opposite those of farmers. By suggesting an information adoption pathway appropriate to each pattern, this study sought to enhance information adoption.

The purpose of this study is to analyze the difference of the visual perception and attention of the people with intellectual disability from the application of the assessment applying an electronic media and traditional paper material. The study subjects were 12 people with intellectual disability, To assess the visual perception, the motor free visual perception test-3 was used and the trail making test was used to assess the visual attention. After the assessment of the visual perception and attention applying the traditional paper material, the assessment applying the electronic media. The results of the visual perception and attention showed the difference of the visual perception and attention, and the scores of the visual perception and attention applying the assessment of the electronic media showed the more higher than the assessment of the traditional paper material. The electronic media could be worked as a factor to increase the visual perception and attention of the people with intellectual disability. Thus, the difference should be considered to apply the electronic media for them.

The purpose of this research is to know the teachers and parents' perception on the National Assessment of Educational Achievement system that has been conducted since 2008 and to obtain the implementation on the National Assessment of Educational Achievement. For this purpose, total of 1,000 questionnaires were distributed to 500 elementary school teachers and 500 parents in Busan, and 766 of the analysis of survey results follows excluding the retrieved and insincerity responses. First, the national assessment showed negative perception from the teachers, whereas the parents were generally positive and the method to reduce the gap of perception is needed. Second, it has to be improved after collecting opinions of a teacher and parents of students for improvement on the National Assessment of Education Achievement and reviewing enough the potential problems in the context of education in Korea and school.

Purpose: This study was conducted to identify the perception, barriers, and importance of delirium assessment of intensive care unit nurses utilizing a tool for delirium assessment. Methods: The subjects were 150 intensive care unit nurses who routinely use the CAM-ICU to screen delirium. Data were collected using self-report questionnaires and analyzed using descriptive statistics and ranking. Results: Most intensive care unit nurses had experience of education about delirium and delirium assessment, and had assessed over once in a shift. However, a small number of nurses recognized utilizing their assessment result and the effect on higher mortality and underdiagnosed and preventable problem. The first rank of barriers was being too busy to assess patients and the second was difficulty of interpreting intubated patients. The importance of delirium assessment was considered lower than assessing catheter placement and level of pain. Conclusion: The study identified intensive care unit nurses' use of a delirium assessment tool, and the perception, barriers, and importance of delirium assessment. Furthermore, it is necessary to develop education programs to improve the early recognition of delirium by intensive care unit nurses.

There has been a continual need for change of teachers' assessment practices as shifting a paradigm in education. Teachers' appropriate perception of assessment influences quality of assessment and leads to change of teachers' assessment practices. This study aimed at investigate prospective elementary teachers' perceptions on assessment in mathematics. To this end, we conducted a survey with the questionnaire which was developed based on previous studies on assessment. The questionnaire was composed of 41 questions about purposes and roles of assessment, materials of assessment, reliability of assessment, methods and strategies of assessment. 95 prospective elementary teachers participated in the survey. As a result, we found that prospective elementary teachers had appropriate perception on roles of assessment, materials of assessment and strategies of assessment, whereas they showed somewhat narrow perception on reliability of assessment, purposes and methods of assessment. Based on the results, we presented possible explanations about prospective elementary teachers' lack of perception on assessment and discussed implications for prospective elementary teacher education.

Background and Objectives: Although many studies have evaluated the effect of the digital noise reduction (DNR) algorithm of hearing aids (HAs) on speech recognition, there are few studies on the effect of DNR on music perception. Therefore, we aimed to evaluate the effect of DNR on music, in addition to speech perception, using objective and subjective measurements. Subjects and Methods: Sixteen HA users participated in this study (58.00±10.44 years; 3 males and 13 females). The objective assessment of speech and music perception was based on the Korean version of the Clinical Assessment of Music Perception test and word and sentence recognition scores. Meanwhile, for the subjective assessment, the quality rating of speech and music as well as self-reported HA benefits were evaluated. Results: There was no improvement conferred with DNR of HAs on the objective assessment tests of speech and music perception. The pitch discrimination at 262 Hz in the DNR-off condition was better than that in the unaided condition (p=0.024); however, the unaided condition and the DNR-on conditions did not differ. In the Korean music background questionnaire, responses regarding ease of communication were better in the DNR-on condition than in the DNR-off condition (p=0.029). Conclusions: Speech and music perception or sound quality did not improve with the activation of DNR. However, DNR positively influenced the listener's subjective listening comfort. The DNR-off condition in HAs may be beneficial for pitch discrimination at some frequencies.

3DTV is expected to be a promising next-generation broadcasting service. On the other hand, the visual discomfort/fatigue problems caused by viewing 3D videos have become an important issue. This paper proposes a perceptual quality assessment metric for a stereoscopic video (SV-PQAM). To model the SV-PQAM, this paper presents the following features: temporal variance, disparity variation in intra-frames, disparity variation in inter-frames and disparity distribution of frame boundary areas, which affect the human perception of depth and visual discomfort for stereoscopic views. The four features were combined into the SV-PQAM, which then becomes a no-reference stereoscopic video quality perception model, as an objective quality assessment metric. The proposed SV-PQAM does not require a depth map but instead uses the disparity information by a simple estimation. The model parameters were estimated based on linear regression from the mean score opinion values obtained from the subjective perception quality assessments. The experimental results showed that the proposed SV-PQAM exhibits high consistency with subjective perception quality assessment results in terms of the Pearson correlation coefficient value of 0.808, and the prediction performance exhibited good consistency with a zero outlier ratio value.
