초기의 웜은 감염 및 확산의 신속성을 중요시하였으나, 생존성은 고려하진 않았다. 하지만 보안도구(Anti-worm)의 발달에 따라 2004년 이후 대규모의 웜 확산에 의한 피해가 보고되지 않고 있다. 이에 웜도 보안도구를 회피하는 자기방어(Self-Defense) 기법을 개발하여 생존성을 증가시키면서 진화하고 있다. 본 논문은 현존하는 웜 자기방어 기법과 그 한계를 분석한 후 행동기반 탐지 기법을 우회하는 자기방어 기법을 제안하도록 하겠다.

This paper presents the analysis of the human driving behavior based on the expression as a GMDH technique focusing on the driver's collision avoidance maneuver. The driving data are collected by using the three dimensional driving simulator based on CAVE, which provides stereoscopic immersive vision. A GMDH is also introduced and applied to the measured data in order to build a mathematical model of driving behavior. From the obtained model, it is found that the longitudinal distance between cars($x_1$), the longitudinal relative velocity($x_2$) and the lateral displacement between cars($x_4$) play important roles in the collision avoidance maneuver under the 3D environments.

In spite of the efforts to reduce traffic accidents of commercial vehicles, the number of driving under the influence (DUI) of commercial drivers has been increasing. This study examines the effect of stress coping style of commercial drivers on driving behaviors. Specifically, this research aims to find the role of life stress as a mediator in the relationships between the stress coping style and problematic drinking behaviors. 1308 licensed commercial vehicle drivers participated in this research. Results showed that life stress mediated the relationships between problem focused strategies, wishful thinking strategies, passive avoidance strategies and problematic drinking behaviors. These findings indicate that educating drivers to change their stress coping styles would be helpful to inhibit them from being involved in drunken driving.

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.

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.

There exists a limitation to provide proper advance information for safe maneuvering through guidance and caution signs in freeway mobile work zones, unlike fixed work zones. Although a work-protection vehicle is currently deployed at the rear of the work vehicle, more active countermeasures to prevent crashes are required. The purpose of this study was to propose a method to evaluate the safety in mobile work zones and to present effective countermeasures. Driving simulation experiments were conducted to analyze characteristics of driver's behavior in mobile and fixed work zones. Safety distance index (SDI) based on the comparison of stopping distances of a work-protection vehicle and a following subject vehicle was used to evaluate traffic safety. More dangerous driving behavior was observed in the mobile work zone. Especially, it was identified that the lane-change of vehicles following the work- protection vehicle was late. Therefore, it is necessary to actively introduce methods to provide warning information so that the driver can recognize the work-protection vehicle in advance and carry out appropriate evasive maneuvers.

The Purpose of this study is to examine the effect of communication competence and empathy on stress coping in college students. The research problems were verified by correlation analysis and multivariate regression analysis. A questionnaire survey was conducted on 292 college students. The findings are as follows. First, college students who have high communication competence show more problem-focused coping, social-support seeking coping, and self-soothing coping in stressful conditions, but less emotion-oriented coping and avoidance-oriented coping. Particularly, it is found that behavioral flexibility in communication competence has the greatest effect on problem-focused coping and emotion-oriented coping. Similarly, affiliation/support influences social support seeking coping, interaction management influences self-soothing coping and avoidance-oriented coping. Second, college students who have high empathy are also found more problem-focused coping, social-support seeking coping, and self-soothing coping in stressful conditions. Especially it is found that role-taking in empathy has the greatest effect on problem-focused coping self-soothing coping. Similarly, emotion recognition influences avoidance-oriented coping, emotional resonance influences emotion-oriented coping, authenticity influences social-support seeking coping.
