The purpose of this study was to clarify the effect of learner variables on triggering state curiosity and state anxiety in confronting scientific task situation for fifth to sixth grades of elementary school. Science curiosity, interest, need for cognition, science self-concept, science anxiety, prior knowledge, and perceived difficulty were selected as learner variables that are expected to affect state curiosity and state anxiety. As a result of this study, the variables that had a significant influence on evoking state curiosity in confronting scientific task situation were in the order of interest, need for cognition, science curiosity, and prior knowledge, and all of these variables had a positive effect. In addition, the variables that significantly affect on evoking state anxiety in confronting scientific task situation were in the order of science anxiety, perceived difficulty, need for cognition, science self-concept, and prior knowledge. Of these, only prior knowledge had a negative effect on evoking state anxiety, and the other variables had a positive effect. The results of this study are expected to broaden the comprehension of students' emotional states in science education, and provide a theoretical foundation for the studies of state curiosity and state anxiety in science learning.

This study was performed to determine the levels of MMSE-K among the elderly people affiliated with long-term care insurance services in rural areas, and to reveal its association with related variables. The interviews were performed, during the period from March 1st, to May 31th, 2009, to 410 elderlies in rural areas. As a results, The prevalence of cognitive functions among all subjects were 80.5% of severe cognitive impairment, 11.7% of mild cognitive impairment, and 7.8% of normal. The prevalence of cognitive functions were lower according to the higher grade of long-term care insurance. And the prevalence of cognitive functions were lower in the group of lower educational level, unemployed, live alone, lower monthly income, bear for living expenses by sons and daughters and medical aid, lower visual acuity, with urinary incontinence, with amnesia, without regular exercise and lower frequency of going out than their respective counterparts. The hierarchial multiple regression analysis was used to reveal the explanatory powers of factors influencing on the cognitive functions level. Such factors as age, bear for living expenses, visual acuity, urinary incontinence, amnesia, regular exercise and grade of long-term care services were significantly influenced with cognitive functions. especially the factors of health status were significantly influenced with cognitive functions.

교차로 지체를 추정하기 위해서는 대기행렬 모형이 적합한데 모든 대기시스템은 시 간의 함수로 운영되므로 우리는 분석하고자 하는 시스템이 가변상태인지 또는 안정상태인지 를 먼저 결정하여야 한다. 신호화된 교차로에 유입·유출되는 특히 유입교통량은 시간대별 변화가 심하다. 미국 HCM에서는 이를 15분 단위로 분석하도록 제안하였으나 신호교차로 체계의 정밀 분석을 위해서는 만족스럽지 못한 시간단위이다. 이러한 문제점을 극복하기 위 해서는 시스템이 안정상태가 아닌 가정으로 접근하여야 하며, 더 나아가 Dynamic한 분석이 요구된다. 안정상태의 지체는 Webster를 비롯한 여러 학자들에 의해 광범위하게 연구되어 왔다. 그러나 그들이 갖는 가정은 일반적으로 비현실적이어서 정밀한 지체추정은 실제로 가 능하지 않다. 안정상태 가정하에서 해법의 결점은 도착교통량이 용량에 다다를수록 더욱 심 하게 되어 비현실적인 지체예측을 하게 된다. 본 논문은 기존 분석방법론의 제반 한계성과 제약성을 검토하고 현실적인 교차로 지체모형을 개발하기 위해 고려되어져햐 할 변수들을 정립하고자 한다.

This paper deals with the anaphoric usage of demonstratives when they refer to what are already mentioned in the context. We examine syntactic, semantic and pragmatic factors that contribute to the choice of demonstratives. As for anaphoric usage, English and Spanish show the even distribution between proximal and distal demonstratives with the meaning of their deictic counterparts. Korean and Russian, however, show the uneven distribution of the more prevalent form (unmarked on) and the lesser one (market one). This study aims at a typological explanation for the anaphoric usage of demonstratives through comparison and contrast with such factors as the distance to the antecedent, cognitive status, psychological distance and the center of attention.

In this study, the relationships among cognitive conflict, situational interest, and conceptual change in studying boiling point were investigated. The differences in the relationships by gender were also investigate. Students of 7th grade(N=370) participated in this study. First, a preconception test was administered to choose students who possessed the misconception studied. After presenting anomalous data, test of response to anomalous data and state interest test were administered. After the instruction with a CAI program, a conception test was administered immediately. The conception test was administered again as a retention test four weeks later. The scores of both cognitive conflicts and state interest test were found to be significantly correlated with the scores of the conception test and the retention test. The results of multiple regression analysis indicated that state interest was significantly more important than cognitive conflict in prediction the degrees of conceptual change and retention of conception. For male students, state interest was the only significant predictor of conceptual change and retention of conception. In contrast, cognitive conflict was the only significant predictor for female students.

자동사의 두 하위부류, 비대격(unaccusative) 동사와 비능격 (unergative)동사는 Perlmutter(1978)의 비대격 가설 (Unaccusative Hypothesis) 이후 여러 관점에서 활발히 노의 되어왔다. 한국어에서는 사건구조적 측면에서 두 부류가 차이를 보이며, 이런 사실은 인간의 인지작용과 밀접한 관련을 맺는다. 사건구조를 과정(process)사건과 상태(state)로 가정할 때 비능격 동사는 과정사건이, 비대격 동사는 상태사건이 부각된다. 비대격 동사도 두 가지 부류로 나뉠 수 있는데, '도착하다'처럼 과정사건이 언어표현에서 중시되지 않고 결과적인 상태부분만 중요시 되는 유형(unacc_type_1)과 '녹다'처럼 과정사건도 중시되는 사건 구조를 지닌 유형(unacc_type_2)이다. 결국 비대격 동사는 결과상태를 중시하는 사건구조를 중요시 하지만 과정사건의 지각 정도에 따라 다른 양상을 보인다. 한편 비대격 동사는 사동사와도 밀접한 연관 관계를 지닌다. 많은 논의에서 비대격/사동의 교체를 논리적 다의어로 보고 분석을 시도해 왔다. 따라서 사동사를 중심으로 분석한 경우와 비대격 동사를 중심으로 분석한 경우가 있다. 본고에서는 사동분석(causative analysis)은 한국어 기술에는 적절치 않다고 판단한다. 사동분석에서 도입하는 행동주의 사건유발부분이 반드시 비대격 동사의 표현에 필수적인 것은 아니기 때문이다. 끝으로 Pustejovsky(1995)의 생성어휘부(Generative Lexicon) 이론을 한국어에 맞게 확장·수정한 이정민·강범모·남승호(1997)의 모형에 따라 두 가지 유형의 비대격 동사의 어휘 의미구조를 표상한다.

This study examined the mental health status (depression, cognitive impairment and dementia) and its association with the related factors in the elderly people who were admitted from long-term care insurance. The study subjects were 1,488 people (male 740, female 748) aged over 70 years of age who had been recognized for long-term care insurance services in the years 2011~2014 from the National Health Insurance Corporation. The data collected from the National Health Insurance Corporation set forth a lifestyle questionnaire, itemized health screening tests, and long-term care as recognition data for research purposes. As a result, depression, cognitive impairment, and dementia of subjects increased significantly with age. As a multiple logistic regression result, the risk ratios of depression, cognitive impairment, and dementia, which indicated the mental health status, were significantly higher in women than in men, in the lower body weight group than in the overweight group, in the smoking group than in the non-smoking group, and in the drinking group than in the non-drinking group. These results suggest that the mental health status (depression, cognitive impairment, and dementia) of subjects decreased with increasing age, particularly the group with poor health related behaviors, such as smoking, drinking, and regular exercise, indicating that the mental health condition is lower than in the good group.

The purpose of this study was to identify the influencing factors of subjective health status among the subjects of the 7th year 3 (2018) National Health and Nutrition Examination Survey, and to help provide programs for improving subjective health status in the future. Data from the 7th Korea National Health and Nutrition Examination Survey(2018) were used. Variables were age, gender, age, subjective health status, subjective body shape recognition, weight change over the past year, usual stress level, walking days per week, and strength training days per week. The higher the number of walking days per week, the lower the usual stress perception level. As the number of strength training days per week increased, the level of stress perception was lower (p<.001). The subjects' subjective health status was found to have a negative effect on their usual stress perception (β=-.759), subjective body shape (β=.111), age (β=.421), and number of days walking per week. (β=.968). Based on this study, it is intended to provide basic data for preparing programs to help improve stress perception and subjective health status in the future.
