Metacognitive monitoring refers to high dimensional cognitive activities. Understanding one's own cognitive processes accurately can make effective controls for their performance. Brain area related with metacognition is PFC which is completed the order of late and it can be inferred that monitoring abilities is developing during late adolescent. In this study, we explored the developmental difference in monitoring accuracy between high school students and college students using by measuring JOL(Judgment of Learning). Participants was asked that they study Spanish-Korean word pairs and judge their future performance of memory. In the result, people in both groups thought that they could remember word pairs better than their actual performance. Absolute bias scores which mean the degree to predict their performance apart from true scores showed the interaction between subject groups and task difficulty. Specifically, people judged their learning state quite accurately in easy task condition. However, in difficult task condition, both groups showed inaccuracy for predicting their learning and the magnitude of the degree was bigger in the group of high school students.

이 논문은 과학영재교육원의 학생 선발과정을 중심으로 과학영재아 판별과정을 분석해보고, 과학영재교육원의 학생 선발과정에서 발생할 수 있는 오류를 점검하여, 이를 보완할 수 있는 개선안을 마련하고자 하는데 목적을 두고 있다. 분석결과 과학, 수학과 관련된 창의적 문제의 지필평가 성적이 선발의 가장 중요한 기준이었다. 지필평가 단계에서 지망분야에 관계없이 과학, 수학 및 창의력검사를 모두 치러야 하는 교육원에 초점을 맞추어 그 점수 활용에 있어서 발생할 수 있는 오류를 점검하였다. A 교육원의 경우 학생 선발은 다단계 평가를 원칙으로 하고 있었으며, 1단계 지필평가에서 과학, 수학, 창의력검사라는 세 과목 시험의 합산점수로서 선발하고 있었다. 이 교육원의 ○○년도 중등과정 응시자 276명을 대상으로 합격자와 불합격자의 지필평가 점수를 분석하여 과학, 수학, 창의력검사의 시행에 오류가 없었는지 점검하였다. 또 이들의 합산에 의한 선발이 의미 있는 결과를 보이는지 분석하였다. 그 결과 과학, 수학, 창의력검사의 상관도분석에서 과학은 수학 및 창의력검사와 유의미한 상관이 있었으나, 수학과 창의력검사는 독립적으로 분석되었다. 또 이들의 합산에 지원분야별 배점으로 계산한 선발은 본래의 취지, 즉 과학, 수학, 창의력에서 모두 우수한 학생을 선발하고자 하는 의도대로 진행되었으나, 판별분석 결과 합격과 불합격자 판별에서 88.1%의 정확도를 보여 다소 오류가 있었음을 발견하였다. 이는 해당년도에 출제된 문제의 난이도 및 시험 과목별 평균점수 차를 고려하지 않아 발생하는 문제로 파악되어져 원점수 대신 표준점수로 변환하여 오류를 보완할 것을 제안한다. 자체와 직접 관련되는 영역으로는 좌반구의 측두엽과 전두엽 부분이 관찰되었다. 특히 한국어 어말어미 산출시 나타나는 형태점화 양상과 관련된 대뇌영역으로 발견된 브로카 영역에서의 활성화는 어미 변환과 관련된 영역이라기보다는 산출시 관련되는 articulation, motor coordinate관련 영역으로 추정되고, 측두엽의 활성화는 형태소, 의미 관련 지식의 data base로 추정된다. 또한 우반구 전두엽 부분에서 관찰된 활성화는 억제관련 영역으로 짐작된다.러한 동물실험이 그 기초를 제공해 줄 수 있을 것이다. 또한 행동성향 및 기억의 종류에 따른 약물효과의 차이는 기억과 관련된 질병인 알츠하이머 환자에 있어 개개인에게 맞는 적절한 특징적인 치료약물이 존재할 것이라는 가능성을 제공해줄 뿐만 아니라 학습과 기억력 증진 효과를 기대해 볼 수 있을 것이라고 생각된다. 및 지역산업발전의 기획${\sim}$조정기구로서, 선진국의 지역발전기구(Regional Development Agency : RDA)인 지역전략산업기획단이 2002년도부터 산업자원부와 9개 시도에 의해 설립되어 지역네트워크의 활성화와 클러스터의 형성 촉진을 하게 되었고 2004년도에는 13개시도로 확대${\sim}$운영되고 있고, 지역특화사업(H/W)과 지역산업기술개발과제(S/W)와 함께 패케지 형태로 지원되며, 주요역할은 크게 지역산업의 정책기획 분야와 평가관리, 지역혁신역량 조사 및 DB구축 등으로 구분된다. 그중에서도 권역별, 지역별, 지역산업진흥사업 육성과 중장기 산업발전계획을 수립하기 위하여 지역혁신역량을 바탕으로 한 지역 Technol

The purpose of this study was to compare the effectiveness of rehabilitation therapy with natural recovery in patients who had dysphagia due to stroke. Swallowing functions were examined on a total of 98 patients with stroke-caused dysphagia based on a videofluoroscopic swallowing study (VFSS) for 8 weeks. The each group was evaluated with DOSS, DSS and FOSS to assess swallowing ability in the first week and re-evaluated in the $8^{th}$ week during the session for investigating the recovery status. The author compared the above initial data and follow-up data using a Mann-Whitney U test, Kruskal-Wallis test and Wilcoxon's Signed Rank test, ANCOVA to confirm statistically controlling for the effects of other continuous variables, performed by IBM SPSS Statistics 20.0 for windows. There was statistically significant recovery in the experimental group except measure of DOSS (p>0.05). In the control group, it showed improvement in all the scales(p<0.05). After terminating each session, the comparison of the two group of patients showed statistical significant differences in DSS and FOSS(p<0.05). These results suggest that possibility of natural neurologic recovery has positive effects on early stage of dysphagia caused by stroke.

대전에 소재하는 C 대학교 병원의 물리치료실에 2003년 5월 9일부터 2004년 10월 20일까지 내원한 환자들 중 견부 통증의 진단으로 치료를 받은 환자 가운데 중추신경계에 손상 병력이 없고, 치료사와 의사소통이 가능한 인지 능력을 가졌으며, 실험에 참가하기로 동의한 환자를 대상으로 내원한 순서에 따라 아로마 초음파군, 아로마군, 초음파군에 각각 30명씩을 배정하여 실험한 결과, 치료의 횟수가 증가함에 따라 통증의 정도를 알아보는 시각적 통증 점수가 감소하였으며(p<0.001), 군 간에 통증 감소의 정도도 차이가 있었다. 사후 검정을 보면 아로마 초음파군과 아로마군의 통증 감소의 정도가 초음파군에 비해 높았다(p<0.001). 또한 치료의 횟수가 증가함에 따라 McGill-Melzac 통증 점수 역시 감소하였으며(p<0.001), 군 간에 차이는 없었지만, 교호작용을 고려하면 아로마를 사용한 군에서 감소 폭이 더 큰 것으로 해석할 수 있다. 압통계의 역치 역시 치료의 횟수가 증가함에 따라 모든 군에서 상승하였으며(p<0.001), 군 간에 역치 증가의 정도에도 차이가 있었는데(p<0.05), 사후 검정을 보면 아로마 초음파군이 아로마군에 비해 역치 증가의 폭이 더 컸다. 따라서 압통계의 역치 증가는 아로마 보다는 초음파에 더 영향을 받는 것으로 생각할 수 있다. 이상의 결과로 볼 때 아로마 오일은 주관적이고, 정서적인 통증을 검사하는 시각적 통증 점수와 McGill-Melzac 점수에 많은 영향을 미치는 반면 조직의 회복에 의해 상승하는 압력 역치를 검사하는 압통계의 수치에는 영향을 적게 미침을 확인할 수 있었으며, 반면 초음파는 주관적, 정서적인 통증의 감소보다는 실제 조직이 회복되면서 감소하는 통증에 더 많은 영향을 미치는 것을 알 수 있었다.

This study investigated the relationships among middle school students' understanding about the nature of scientific knowledge, conceptual understanding, and learning strategies. Grade 7 students (N=162) in Incheon completed the nature of scientific knowledge scales (NSKS) and a learning strategy questionnaire. After learning density by way of a CAl program, a conception test was administered. Results indicated that students' conceptual understanding and both deep and surface learning strategies were significantly correlated to their understanding about the nature of scientific knowledge. A cluster analysis was used to classify students on the basis of their deep and surface learning strategies. Three clusters of students with distinctive learning strategy patterns were found; high deep-low surface strategy (cluster 1), low deep-high surface strategy (cluster 2), and high deep-high surface strategy (cluster 3). One-way ANOVA results revealed that the scores of cluster 3 were significantly higher than those of the others in the NSKS and the conception test. Additionally, cluster 1 also performed better than cluster 2 in the conception test. Lastly, educational implications were discussed.

The present study investigates the effect of the inter-aural level difference(ILD) on the syllable articulation test in classrooms which can be occurred by the absorption of interior surfaces. In order to do this, the sound absorbing materials were installed in the classroom and sound pressure level(SPL) at each ear was measured using binaural recording systems. Also, syllable articulation tests were carried out at a classroom with and without sound absorption materials by 20 students who have normal hearing condition, in order to investigates the effect of the ILD on the speech intelligibility. As a result, it was found that the larger inter-aural level differences was occurred at the nearer positions to lateral walls after sound absorptions were applied to lateral walls in the classroom. At some places, the measured ILD was lager than JND of sound level (3dB). Also, it was shown that the correlation coefficient of inter-aural level difference with the score of syllable test has the significant result(-0.441). Thus, It is concluded that ILD can affect the subjective speech intelligibility in classrooms.

The purpose of this study was to survey and analyze the effects of job satisfaction and job stress on organizational commitment among radiological technologist working in primary, secondary and tertiary hospitals in Busan. As a result, the scores of job satisfaction and organizational effectiveness of the tertiary hospital were significantly higher (p<0.05). In the group with no turnover experience, the organizational commitment, job satisfaction, and organizational effectiveness scores were significantly higher (p<0.05, p<0.01). Job stress was not statistically significant between variables in the analysis of general characteristics. Hierarchical regression analysis showed that the radiological technologist organizational commitment had the highest impact on job satisfaction (β=0.703, p<0.001). Radiological technologist are important in the diagnosis and radiation therapy of diseases in hospital. Therefore, based on the results of this study, it will be helpful to analyze the relationship between job satisfaction, job stress and organizational commitment of radiological technologist, and to prepare a plan to increase their organizational commitment.

Steam cakes were prepared with the addition of pine needle powder(Pinus densiflora Seib. et Zucc) at 0%, 1%, 2%, 3%, 4%, and their sensory quality and mechanical characteristics were compared. Sensory evaluation was performed and compared between the subjects in twenties and forties of age. As a result of the sensory evaluation in forties, steam cake with 3% pine needle powder showed the highest score in overall acceptability; however, in the group of twenties, control cake with no pine needle powder showed the highest score. In the measurement of color changes, L value(lightness) was decreased, but a value(redness) and b value(yellowness) were increased as the addition of pine needle powder increased. In textural characteristics, the hardness, springiness, gumminess and brittleness of steam cake were decreased by the increase of pine needle powder. The hardness and brittleness were increased as the storage time increased.

The purpose of this study was to examine the effect of the consistent presentation of illustrations about the aligning direction of the Axis on the middle school students' acquisition and retention of astronomical concepts. This study was taken using the nonequivalent control-group pretest-posttest design on 116 7th middle school subjects. The same teaching and learning activities were given to both the experimental (n=59) and control groups (n=57) through three lessons. The experimental group was given a consistent presentation of the illustrations about the aligning direction of the Axis, while the control group was given an inconsistent presentation of the same illustrations about aligning direction. Two days after the three lessons, the 1st posttest was administered to compare the statistical difference of mean of both groups, using ANCOVA test. The result of ANCOVA test implicated that the consistent presentation of the illustrations about the aligning direction of the Axis had a positive influence on the experimental group's acquisition of the concepts. The 2nd posttest result for retention effect was given two month later by one-paired t-Test in each group and showed that the method had a positive effect on the experimental group, compared with control group. The results of this study implicated that paying careful attention to using the consistent illustration is highly beneficial for students' meaningful learning on astronomical concepts.
