The objective of the study is to find out the effects of toddler's temperament and mother's parenting behavior on the development of vocabulary ability. The study was conducted with 299 infants between the ages of 18 and 24 months and their mothers in 47 day care centers in I city, Jeollabukdo. The results of the study are as follows. First, according to the correlation between infant's temperament and vocabulary based on the composition of temperament, approach-avoidance, adaptability, and mood showed a negative correlation with receptive and expressive vocabulary, and response intensity showed a positive correlation with receptive vocabulary. Second, according to the relation between mother's parenting behavior and infant's vocabulary ability based on the sub-factors of mother's parenting behavior, instructional parenting behavior and setting-limits parenting behavior showed a positive correlation with receptive and expressive vocabulary. Third, according to the effects of infant's temperament and mother's parenting behavior on the development of infant's vocabulary ability, as for the understanding of vocabulary, the explanation power of approach-avoidance is the highest, followed by instructional parenting behavior, response intensity, and mood. As for expressive vocabulary, the explanation power of instructional parenting behavior is the highest, followed by mood, response intensity and activity. In the development of infant's vocabulary ability, it was found that receptive vocabulary was affected the most by approach-avoidance, and expressive vocabulary was affected the most by instructional parenting behavior. Mothers will have to have interrelation skills suitable for temperament for the development of infant's receptive vocabulary, and have parenting behavior expressing the traits of things and events for the development of expressive vocabulary.

The objective of the present study was to investigate the behavioral responses of sillkworm (Bombyx mori) larvae to: the dominant effect of walking distace: and the relationships between walking distance and the various economic characters on yellow sheets. The means of walking distances of progeny from F2 and F1 F1 and F2 generations, which was a hybrid between the long and the short walking distances, were shorter than those of parents. This may indicate that the genes for the short walking distances were partially dominant over those for the longwalking. Estimated broad sense heritability of larval walking distance was different for each larval instar, which fell into the range of 52∼84%. Genetic correlation was apparent between walking distances of all larval stages and some economic characters. The number of cocoons per liter and the period from incubation to emergence have shown the positive genetic correlation with walking distances. The cocoon yield, the sing cocoon weight, and the cocoon shell weight have shown to be in the negative correlation with walking distances. No correlation was observed between walking distances of the mature larvae and any economic characters. The analysis by the path coefficient showed negative direct effect of walking distances on the cocoon yield, and positive indirect effect on the single cocoon weight and the cocoon shell weight.

The study explored the extent of the effect of content book trailer services among the specialized services of the library using the latest technology. The AIDMA&AISAS model was employed to measure the seven reactions of user behavior: Attention, Interest, Search, Desire, Memory, Action, and Share. A total of 287 responses were analyzed by conducting surveys with users who had experienced book trailer services at 13 public libraries located in Incheon. The study found that there were significant differences in user behavioral reactions in all of the content genre, including message, conflict, and character, and in particular, the character genre had the highest effects, followed by conflict and message genres. However, the post-hoc test indicated that there was no significant difference between the genres of conflict and character in terms of interest, search, and user satisfaction. The present study suggests theoretical implications by assessing and confirming the effects of book trailer services of the content genre on the reactions of user behavior compared with previous studies that measured the effects of the book trailer services of the form genre, and further practical implications for effective book trailer services.

Existing toxicity assessment researches were rarely studied on assessment of the abnormal behavior that affecting survival. Therefore, the study used anti-predator response of amphibians larvae, based on behavioral understanding, to assess toxicity in fullerene nanowhisker(FNW) and fullerene nanowhisker-silver nanoparticle composites(FNW-Ag). The experiment was conducted by dividing the groups not exposed to nanomaterials and exposed to nanomaterials at five concentrations(FNW: $10{\mu}g/ml$, FNW: $100{\mu}g/ml$, FNW: $500{\mu}g/ml$ FNW-Ag: $10{\mu}g/ml$, FNW: $50{\mu}g/ml$). As a result, there were no differences in normal activity except those exposed to concentrations of FNW-Ag $50{\mu}g/ml$, but there were statistically significant differences in anti-predator response except those exposed to concentrations of FNW $10{\mu}g/ml$. That is, exposed of nanomaterials does not affect ordinary movements, but analyses based on behavioral understandings have shown that it has an influence on the anti-predator response. It is therefore considered necessary to have animal behavioral analysis method performed in the assessment of eco-toxic experiment.

This study preformed a research about the traffic signal light that is adding supplementary green light to prevent driver's cognitive errors and plan safe driving through improving visual cognitivity of present traffic signal light. The result of comparing the present traffic signal light(three colors, four colors) with the traffic signal light(three colors, four colors) adding supplementary green light through car simulator has a significant difference. This result shows possibility that the traffic signal light adding supplementary green light can contribute in safety driving at a point that the traffic signal light advances a point of braking time when drivers didn't recognize by themselves. The findings in this study ca say that there is the meaning in showing a actual application possibility of this study finding by investigating a action of subjective response the moment compare driver's actual response.

본 연구는 가상환경에서 위반행동을 한 사람에게 그 행동에 관한 단서를 제시하였을 때 나타나는 심리 생리적 변화를 측정하고자 한다. 피험자는 가상환경에서 주어진 시나리오에 따라 목적지까지 자동차를 운전하는 역할을 수행한다. 시나리오는 운전을 하는 도중에 사고를 내고 차량을 수리하는 내용으로 구성하였다. 피험자는 위반, 관찰, 통제집단의 세 집단으로 선별되며, 위반집단은 고의적으로 교통사고를 일으키게 된다. 위반 행동을 한 피험자에게 사건에 관련된 질문을 컴퓨터로 제시하고 동시에 뇌파를 측정한다. 사건 관련 질문은 위반행동과 관련이 있는 장소, 차량, 행동에 대한 답변보기들로 구성되었으며 피험자에게는 위반행동과 무관한 보기답안과 함께 제시된다. 측정결과, 위반행동과 무관한 보기답안 보다 위반행동과 관련된 보기답안에서 높은 뇌파 반응이 나타났다. 따라서 이를 이용하여 위반행동을 탐지하는 것이 가능할 것으로 보인다. 연구 확장을 통해 가상환경으로 실제 위반 상황을 재구성하여 적용하는 것도 유용해 보인다.

The purpose of the present study was to examine how 25~36-month-old toddlers' temperament, mother's rearing attitude, teacher interaction relates to their language abilities and to analyze the predictive power of these variables in predicting language ability. The subjects were 206 toddlers, 206 mothers and 38 class teachers at child care center in G metropolitan city. The collected data were analyzed using Pearson's correlation analysis and stepwise multiple regression analysis on SPSS program. The results of this study were as follow. First, there was a significant relationship between mother's rearing attitude, teacher interaction and toddlers language abilities. However, toddlers' temperament showed no significant correlations with toddlers language abilities. Second, teacher's positive attitude was the best predictor of toddlers language abilities. Toddlers' reactivity and mother's rational guidance were also predictors of toddlers' language abilities.

가상현실을 이용한 교육시스템에서 학습자를 대신한 에이전트의 설계에 대한 많은 연구가 이루어지고 있다. 이러한 에이전트의 설계에 있어서 가장 중요한 점은 동적으로 변화되는 환경에서 이루어지는 다양한 현상과 사건들을 인식하는 방법과 이에 대해 반응하는 행동의 설계와 구현에 있다. 본 논문에서는 에이전트의 행동을 설계함에 있어서 교육 시스템의 목적에 부합하기 위한 주위 객체들과의 상호작용을 통한 행위의 인식, 장이론을 이용한 공간객체와의 상호작용 등을 이용하여 좀 더 효율적으로 주위 환경에 반응할 수 있는 자율 에이전트의 행위에 대한 방안을 제시한다.

사화나 경제와 같은 동적 시스템에서 행동에 대한 적절성은 주위의 개체들에 의해 평가되고 일반적으로 동적 시스템에서 개체들의 행동은 주위 상황의 변화에 민감한 자극-반응의 형태로 나뉜다. 본 논문에서는 그와 같은 동적 시스템을 간단한 반복적 죄수의 딜레마게임으로 모델링하고 에이전트들의 연합을 통해 일반화 능력을 향상시킴으로써 환경변화에 보다 적응적으로 반응하도록 한다. 이를 위해 반복적 죄수의 딜레마 게임에서 획득된 전략 연합에서 에이전트들의 신뢰도를 조정함으로써 일반화 능력이 향상되도록 하였다. 실험결과, 전략 연합에서 에이전트들의 신뢰도를 진화적으로 조정함으로써 일반화 능력을 크게 향상시킬 수 있음을 볼 수 있었다.
