This study seeks educational implication by analyzing research papers dealing with science assessment in the most recent 30 years in Korea. The main purpose of the study is to analyze the trends in published papers on science assessment, their purpose, methodology, and key words, especially concentrating on the cognitive and affective domains. We selected 273 research articles and categorized them by research object, subject, methodology, and contents. To examine the factors that affect the research trend, we also tried to contextualize papers' theme in terms of changes in national curriculum and assessment system during the contemporary period. As a result, an overall research trend reflects changes in science curriculum and assessment events such as implementation of college scholastic ability test or performance assessment. There is an unequal distribution in various aspects of the researches, showing a superiority in cognitive domains than the affective ones. By using standardized data obtained through the national and international assessment of educational achievement in science, quantitative researches were superior to qualitative ones. Studies on cognitive domain use variously written- and performance-based tests, whereas most studies of the affective ones prefer written tests. Applied research and evaluation research are predominant comparing to basic ones, which most of the research methodology is based on statistics. Lastly, we found out that key words and subjects tend to be subdivided and detailed rather than general and comprehensive, as time goes on. Such trend will be helpful to elaborate and refine assessment tools that have been regarded as a problem.

조직이나 기업에서 높은 수준의 직무 성과는 뛰어난 지적 능력과 더불어 다른 요소들의 영향에 의해 결정된다고 광범위하게 인식되고 있다. 따라서 인사선발시 인지적인 능력뿐만이 아니라 성격과 같은 비인지적 능력을 평가하는 시도가 활발히 이루어지고 있다. 본 연구는 이를 실증적으로 검증하고자 수행되었다. 즉, 본 연구에서는 서울지역에서 재학 중인 대학생 (n=260) 을 대상으로 하여 인지적 능력은 입학성적으로, 비인적 능력은 Big Five 성격 특성으로, 직무성과는 학업성과(예, 학업평점, 대학 및 학과에 대한 만족도, 동아리 활동, 등) 로 각각 측정하여 이들의 관계성을 살펴보았다. 연구 결과, 인지적 능력과 더불어 Big Five 성격 특성 중 성실성과 개방성이 다양한 학업성과와 상관관계를 보여주었다. 본 연구는 추가적으로, 학업성과 중 동아리 활동이 대학생활의 만족도와 상관관계가 있음을 보여주고 있다. 이러한 결과는 인사선발 과정에서 지원자의 잠재적 직무성과를 예측할 때 지적 능력 같은 인지적 측면뿐만이 아니라 성격과 같은 비인지적 측면을 동시에 고려해야 한다는 실무적 시사점을 제시하고 있다.

The transmission issues for the scalable video coding extension of H.264/AVC (H.264 SVC) video has been widely studied. In this paper, we propose an objective video-quality assessment metric based on no-reference for H.264 SVC using scalability information. The proposed metric estimate the perceptual video-quality reflecting error conditions with the consideration of the motion vectors, error propagation patterns with the hierarchical prediction structure, quantization parameters, and number of frame which damaged by packet loss. The proposed metric reflects the human perceptual quality of video and we evaluate the performance of proposed metric by using correlation relationship between differential mean opinion score (DMOS) as a subjective quality and proposed one.

Cognitive-linguistic changes that normally accompany aging are often simply an annoyance, but in some instances they may herald a more perilous course of decline to a state of neurological disease. This study investigated the correlation between subjective and objective tests on cognitive-linguistic abilities in older adults and the predictors of objective performances. Healthy elders over 65 years of age (n=63) and their informants (n=63) completed the subjective and objective cognitive-linguistic tests (ISCOLE and CAPTBI) from July of 2015 to February of 2016. The main findings were as follows: performance on the self-report test was not significantly different from that on the informant-report test. Additionally, eight domains in older adults group and 15 domains in the informants group were significantly associated with performance on the objective test. Finally, language on the informant-report test was a predictor of several abilities including problem solving and memory on the informant-report test predicted executive function and language. The present study demonstrates that two groups have significant differences in correlation between subjective and objective tests on the cognitive-linguistic abilities, and there are more relevant domains in rating by informants. These findings have implications for the use of cognitive-linguistic evaluation and preventive intervention in clinical settings.

The purpose of this study was to examine how constructive-response questions in regular test was in aligned with the nature and goals of 2007 Curriculum Amendment. For this purpose, data were collected and analysed by using the framework for mathematical task and the cognitive demand of tasks suggested by Smith & Stein(1998) and mathematical proficiency suggested by National Research Council(2001). In particular, it aimed to reveal the overall picture of the level of cognitive demand and the proportion of mathematical proficiency of constructed-response items created by secondary mathematics teachers. The findings from the analysis showed that 70 percent of the constructed-response items were at low-level and the rest at high-level in terms of cognitive demand. Also, the constructed-response assessment focused on conputing (89%), understanding(45%), applying(30%) and least reasoning(17%). Most of the constructed-response items included computing and were algorithmic.

This research purposes to find out the mathematical cognitive characteristics of Korean students and compare it with that of TIMSS 2011 high-achieving countries based on the Cognitive Diagnostic Theory. Based on framework and questions of TIMSS 2011, we select cognitive attributes. Using the data of 8th grade students' mathematical achievement in TIMSS 2011, we compare and analyze the top 15-countries students' cognitive traits. As a result, cognition domain of TIMSS 2011 is reclassified as 9 cognitive attributes. we could distinguish between easy attributes and difficult attributes that students in each country relatively think. Especially, Students of Korea relatively think Recall/Recognize, Compute, Classify/Measure and Represent are easy. On the other hand, relatively they have difficulties in Retrieve, Implement, and Generalize. Based on this research result, It is necessary to establish an educational measures for each attributes which students have difficulties.

Cognitive-communicative disorders after traumatic brain injury(TBI) and right hemisphere damage(RHD) are different from other neurological disorders in nature. Therefore, it is not desirable to use aphasia tests in evaluating individuals with TBI or RHD. The aim of this study is to review assessment protocols on TBI and RHD, and literature related with them. As a result, it is recommended that individuals with TBI be examined in scope of the cognition including attention, memory, organization, reasoning, as well as the functional communication. Similarly, it is useful to consider high-order language related to various cognitive domains in assessing cognitive-communicative ability after RHD. In conclusion, we need to focus on the overall cognitive-communicative domains in an evaluative process of TBI and RHD. Furthermore, it is necessary to develop multiple items for individuals with cognitivecommunicative disorders for the purpose of differentiating these heterogeneous groups from other neurological disorders such as aphasia, and of making good use of them as a therapeutic manual.
