We investigated the differences between the teachers' perception and practice on portfolio assessments in kindergartens and daycare centers, and analyzed their dependence on various underlying factors. The participants of this study include 304 teachers in the kindergartens and daycare centers in J I G cities in Jeollabuk-do. The answers on the questionnaires were analysed by evaluating frequencies, percentage, averages, and standard deviations, and by carrying out paired t-test, ANOVA, and Scheff$\acute{e}$ verification using SPSS 18.0 program. The results of this study are summarized as follows. First, teachers' practice fell meaningfully short of their perception in every sub-categories of the method and the effect of the portfolio assessment. Among the various underlying factors, only teachers' educational level played significant role. The difference between the perception and practice was relatively large among the teachers with regular 4-year college diploma as compared to junior-college graduates. Second, as we examine the difficulties in the portfolio assessment, teachers in general found difficulties on the questionnaires in all sub-categories, although the dependence on the underlying factors varies across the sub-categories. For example, teachers with higher level of education or who work at public kindergartens felt relatively more difficulties in the portfolio assessment.

This study was to investigate the perception, performance, and difficulties of process-based assessment for high school mathematics teachers. As a qualitative case study, two in-depth group interviews were conducted with 6 high school mathematics teachers working in Incheon area. The two groups were one with more experience in process-based assessment and the other with less experience. As results, there were differences between the participant teachers' perception of process-based assessment and their actual performance depending on the experience. All six math teachers thought that the process-based assessment was intended to confirm the learner's characteristics, to evaluate the process, and to provide feedback on a regular basis immediately and individually. However, in the practical performance shared by teachers, the purpose of assessment was to create a school record. A group with a lot of experience prepared assessment criteria according to the national curriculum achievement standards, established affective assessment plans, and tried to provide individual feedback on a regular basis. On the other hand, the inexperienced group recorded the affective characteristics discovered by chance and provided temporary and large-scale feedback regardless of the achievement criteria. Finally, we suggested some implications based on the study results.

본 논문에서는 ETRI에서 개발한 가변 어휘 음성 인식기의 어휘 독립 음향 모델링 방법을 기술하고, 이 모델의 어휘 종속, 어휘 독립 및 어휘적응 성능을 평가하기 위하여 다 양한 고립단어 및 연속음성 DB에 대하여 실험한 결과를 분석하였다. 평가를 위하여 사용한 음성 DB로는 고립단어 음성으로 POW(Phonetically Optimized Words) 3848, PBW(Phonetically Balanced Words) 445, PBW 452, 호텔예약 244 단어, 게임 제어용 단어 등이며, 연속음성으로 일반 문장 음성 및 연속 숫자음을 이용하였다. 성능 분석 결과 40개 음소 모델만으로도 비교적 높은 인식률을 보여 주었지만, 어휘독립의 경우는 어휘종속에 비 하여 성능이 크게 낮았고, 특히 대상 어휘가 숫자음, 알파벳, 연속음 등의 경우에는 POW 데이터나 PBW 데이터만 가지고는 우수한 가변 어휘 음성 인식기를 구현하기에 한계가 있 음을 알 수 있다. 또한, 훈련 데이터의 어휘와 평가데이터의 어휘가 비슷할 경우에는 변이음 모델을 사용하면 음소 모델만을 사용할 경우에 비하여 그 성능이 우수하였지만, 일반적인 어휘독립의 상황에서는 효과가 별로 없음을 알 수 있었다.

This is a survey study to measure degrees of understanding regarding Information literacy in Korean university students based on ACRL standards. In the results of the survey there were no meaningful differences between individuals age, gender, major, and University. There were also no meaningful difference between the five ACRL standards. However, there were meaningful differences between the performance indicators in each standard. For example in the first standard, the performance indicator 'Determines the nature and extent of the information needed', had the highest score. had the lowest score. In the second ‘Effective Access of Information', had the highest score. In the third ‘Evaluate and Incorporate Information', had the highest score>and had the lowest score. In the fourth ‘Use of Information', , had the highest score. In the last ‘Information Ethics', there was no meaningful difference. This study also showed outcomes regarding the details in each standard.

본 연구에서는 연령증가에 따라 운전에 필요한 신체적, 인지적 능력의 변화가 어떻게 나타나는지 설문을 통해 분석하고, 이것이 교통안전 시설물(신호기, 노면표시, 도로표지판)의 필요성 및 적정성을 평가하는 것과 어떤 관계가 있는 지 살펴보고자 하였다. 이를 위해 20세 이상 운전면허 소지자를 대상으로 5개 권역, 500명을 대상으로 설문조사를 실시하여 이를 분석하였다. 운전능력에 대한 자기평가 점수는 종합적 능력, 개별능력(시력, 청력, 색채식별 등) 모두 연령이 증가함에 따라 점수가 낮아지는 것으로 분석되었다. 특히 시력은 연령증가에 따른 감소폭이 크고, 절대적인 평균점수가 다른 항목에 비하여 낮게 나타났다. 시력의 경우 타 신체적, 인지적 능력에 비해 운전 중 기능의 저하에 따른 체감도가 크기 때문인 것으로 판단된다. 설문결과에 따른 분류분석을 통해서는 신체적, 인지적 기능의 저하가 시작되는 연령이 기존의 고령운전자로 판단하는 65세 보다 낮은 48세로 분석되었다. 이것은 연령증가에 따른 기능 저하로 인한 영향을 받는 운전자가 그렇지 않은 운전자보다 더 많다는 것을 의미한다. 또한 시설물에 대한 필요성 인식에 대한 평가 역시 운전능력에서 차이를 나타내는 연령대에서 인식의 차이가 있을 것으로 분석되었다.

This study was to identify the differences on cognitions for conservation on the Rice Terraces landscape between local residents and visitors. For this purpose, this study drew problems and implications through consideration about advanced studies and then carried out a survey of local residents and visitors. The results of this study analyzed five factors that are the components of cognition about the Rice Terraces landscape: production, policy, landscape, management, and revitalization. The Cognition of Rice Terraces landscape indicated that local residents had more positive evaluation than visitors did. In addition, there were indicated differences in most items. Particularly, the local residents had more positive evaluation than visitors did in production(rice paddy of fallow ground, form of traditional rice paddy, weeds), landscape(cultural value, footpath of rice field and stonewall), and revitalization(common program for local residents and visitors, village revitalization from festival and event). Visitors had a more positive evaluation than local residents in terms of policy(designation of a place of scenic beauty, direct payment) and management(cooperation of local residents and visitors). In consideration of these results, it needs to draw up measures that are able to build up a common cognition to overcome differences between local residents and visitors. It is based on the knowledge and opinions that visitors and local residents had concerning history, traditions, cultures and production.

The purpose of this study was to examine the perception of the childcare teachers regarding accreditation procedures and feasibility of the second accreditation index according their past participation in the accreditation process. The objects were 193 childcare teachers working at child care centers that were accredited using the initial accreditation index. The collected data was analyzed using frequency, percentile, $X^2$, and t-test. The major findings are as follows: First, childcare teachers without accreditation experience perceived 'continuing education of child care center directors and teachers' to be the most important for quality maintenance after successful accreditation. In contrast, childcare teachers with accreditation experience placed the most importance on 'childcare teachers' motivation and continuing enrollment'. Second, childcare teachers with accreditation experience perceived higher feasibility in the subcategories of 'art activity materials' in the category of child care environment, 'providing operation policies and information of child care teachers', 'care for children', and 'employment contract' in the operation & management category, 'sanitary management of food, cooking and feeding', 'care of sick or injured child', 'health management of children and childcare teachers', 'snacks for children' in the category of health and nutrition and 'safe procedures for handing over children' in the category of safety. In general, childcare teachers with accreditation experience perceived higher feasibility of the second accreditation index in all categories.
