플레이어의 흥미를 유발하기 위해서 보다 현실감 있는 캐릭터의 중요성이 증대됨에 따라, 캐릭터 디자인 단계에서 성격을 적용하여 사람처럼 행동하는 캐릭터가 필요한 시점이다. 그러나 기존 게임 캐릭터는 개발 단계에서 성격이 정해진 것이 아니므로 사람과 비슷한 행동을 하고 표현을 하는 캐릭터를 창출하는 데는 한계가 있다. 따라서 본 논문에서는 게임 캐릭터에 적용하기 위한 목적으로 5대 성격요인과 자아 상태의 연관성을 증명한다. 5대 성격요인과 자아 상태는 모두 사람의 성격적인 특성과 관련된 이론이다. 5대 성격요인은 사람의 내부적인 특성을, 자아 상태는 외부적으로 관찰 가능한 사람의 특성을 중점으로 하고 있다. 이점에서 두 이론은 어떠한 특성을 정의하고 이에 따라 행동하도록 설계된 캐릭터에 적용하기 적합하다. 즉, 5대 성격요인의 성격에 따라 설정되고, 자아 상태를 이용하여 이 성격에 따른 행동을 표현하는 캐릭터를 개발할 수 있다. 이 작업을 위해서는 우선 두 이론에 관련이 있음을 밝혀낼 필요가 있다. 이를 위해 본 논문에서는 기존 성격연구에 활용된 방법론인 형용사 체크리스트를 이용해 두 이론의 연관성을 밝혀내고 이 결과를 설문을 이용하여 분석한다. 향후 이 두 이론의 연관성에 따른 성격 모델을 구축하여, 캐릭터가 성격에 따라 행동하는 즉, 사실적 행위에 기반을 둔 캐릭터를 개발할 수 있을 것이라 기대한다.

Distance dynamics model is an excellent model for uncovering the community structure of a complex network. However, the model has poor robustness. To improve the robustness, we design an enhanced distance dynamics model based on Ego-Leader and propose a corresponding community detection algorithm, called E-Attractor. The main contributions of E-Attractor are as follows. First, to get rid of sensitive parameter ${\lambda}$, Ego-Leader is introduced into the distance dynamics model to determine the influence of an exclusive neighbor on the distance. Second, based on top-k Ego-Leader, we design an enhanced distance dynamics model. In contrast to the traditional model, enhanced model has better robustness for all networks. Extensive experiments show that E-Attractor has good performance relative to several state-of-the-art algorithms.

Objective : The aim of this study was to investigate the prevalence of anxiety symptoms and its association with psychological factors in patients with hypertension. Methods : The Participants included 124 patients with hypertension. Anxiety symptoms were evaluated by the Hospital Anxiety and Depression Scale. Socio-demographics, perceived stress, state-trait anger, life satisfaction, and ego resiliency were assessed. Stepwise multiple regression analyses were carried out to examine the impact of perceived stress, state-trait anger, and life satisfaction on anxiety symptoms. In addition, moderated regression analysis was performed to explore the moderating effect of ego resiliency between perceived stress and anxiety symptoms. Results : A total of 17 subjects (13.7%) were identified as having anxiety symptoms. Higher perceived stress and state-trait anger, and lower life satisfaction were found to be significant correlates of anxiety symptoms. In the final model, higher levels of perceived stress (β=0.378, p<0.001) and trait anger (β=0.320, p<0.001) were related to higher levels of anxiety symptoms, while a higher level of life satisfaction (β=-0.166, p=0.025) was associated with a lower level of anxiety symptoms. Further, ego resiliency buffered the negative effect of perceived stress on anxiety symptoms. Conclusion : This study demonstrated the prevalence of anxiety symptoms and associated psychological factors among patients with hypertension. Our findings suggest that improving life satisfaction and ego-resiliency as well as controlling stress and anger may be important in the management of anxiety symptoms in patients with hypertension.

This paper presents a novel methodology for estimating vehicle ego-motion, i.e. tri-axis linear velocities and angular velocities by using stereo vision sensor and 2G1Y sensor (longitudinal acceleration, lateral acceleration, and yaw rate). The estimated ego-motion information can be utilized to predict future ego-path and improve the accuracy of 3D coordinate of obstacle by compensating for disturbance from vehicle movement representatively for collision avoidance system. For the purpose of incorporating vehicle dynamic characteristics into ego-motion estimation, the state evolution model of Kalman filter has been augmented with lateral vehicle dynamics and the vanishing point estimation has been also taken into account because the optical flow radiates from a vanishing point which might be varied due to vehicle pitch motion. Experimental results based on real-world data have shown the effectiveness of the proposed methodology in view of accuracy.

본 연구의 목적은 흡연여부에 따라 대학생이 인지하는 스트레스와 우울의 관계에 있어 개인의 자아상태의 조절효과를 확인했다. 연구결과, 대학생이 인지하는 스트레스와 우울은 밀접한 관련이 있는 것으로 나타났으며, 자아상태의 조절효과는 흡연군과 비흡연군에서 각각 다르게 나타났다. 비흡연군에서는 자신에 대한 엄격한 통제를 추구하는 CP 성향이 우울을 낮추는 조절효과를 보였고, 흡연군에서는 뛰어난 적응성과 창조력, 자율성이 풍부한 A 성향이 우울을 낮추는 효과를 보였다. 반면, 흡연군에서는 AC 성향도 유의한 조절효과를 보였는데, AC 성향이 높은 경우 자신이 처한 상황에 대해 무력감을 느끼고 현실에 순응하는 부정적인 감정을 유발할 수 있다고 보고된다. 자아상태의 조절효과는 스트레스, 우울과 같은 정서적 상태에의 접근에 있어 개인이 지닌 성향을 함께 고려하여 접근해야 함을 시사한다.

This paper describes the development of a target vehicle state estimation algorithm using vehicle-to-vehicle (V2V) communication. Perceiving the state of the target vehicle has great importance for successful autonomous driving and has been studied using various sensors and methods for many years. V2V communication has advantage of not being constrained by surrounding circumstances relative to other sensors. In this paper, we adopt the V2V signal for estimating the target vehicle state. Since applying only the V2V signal is improper by its low frequency and latency, the signal is used as additional measured data to improve the estimation accuracy. We estimate the target vehicle state using Extended Kalman filter (EKF); a point mass model was utilized in process update to predict the state of next step. The process update is followed by measurement update when ego vehicle receives V2V information. The proposed study evaluated state estimation by comparing input V2V information in an experiment where the ego vehicle follows the target vehicle behind it.

The purpose of this study is to analyze the type of ego states and stress coping style on female college students who are in the course of nursing study. This study is performed in the view of Transactional Analysis and designed to scrutinize descriptive correlations between the type of ego states and stress coping style. The subject is consists of 144 freshmen and sophomore, 138 junior and senior students group, who are students of K nursing college located in Seoul. The sampling investigation period is on Sept. 14, 2002 to Oct. 26, 2002. The measuring instrument used for Transactional Analysis ego state is 50 items Ego-gram research paper devised by Dusay(1997). For studying coping style, Folkman & Lazarus's measurement(1984) was adopted, which is translated and modified by Han, and Oh,(1990). Statistic average and standard deviation were generated by using SPSS PC+, t-test and Pearson correlation. The results were as follows: 1) In the type of ego states on both groups(lower group : freshmen, sophomore upper group : junior, senior) indicated the arithmetic apex NP(maximum value), then the point A was high and the data made a down slope to point AC. In the comparison to type of ego states between two groups, only at point CP, the data value of upper year students represented higher than that of lower year ones by C(t=2.28, p=.023). In the psychological energy level of ego states, both groups indicated average level.2) Stress coping style of whole students were highly and affirmatively dedicated to research. Consecutive consequences follow like this(high to low) : the central point of problem, search for social support, hopeful aspect and indifference. Especially hopeful aspect(t=.67, p=.05), relaxation of tension(t=-2.16, p=.03) made significant difference each other in the view of arithmetic calculation 3) While verifying coping style in terms of ego states level between lower and upper students group, In type CP, high level ego states group indicated significant difference on stress coping style area than low leveled group and made such sequences as the central point of problem, hopeful aspect, search for social support, positive interest and relaxation of tension. In type NP, sequences such as the central point of problem, search for social support, positive interest and relaxation of tension were emerged with little differences. In type A, the central point of problem, positive interest and relaxation of tension. In type FC, hopeful aspect, search for social support, positive interest and relaxation of tension. In type AC, hopeful aspect and indifference were derived significantly different(p<.05). 4) In the aspect of relation between ego states and coping style, type CP presented the central point of problem and relaxation of tension, type NP presented positive interest, search for social support and the central point of problem, type A showed the central point of problem, positive interest and relaxation of tension, type FC showed relaxation of tension, positive interest, search for social support, indifference and the central point of problem, type AC showed hopeful aspect, indifference and the central point of problem. All the sequence shown above had high-to-low procedure and represented static relations each other(p<.05).

This study aimed to verify the positive effects of forest activities for children from economically underprivileged households in local children's centers and the effect of such activities on the protective factors of their development. One hundred and eighty five children participated in the Forest Activities Program, which conducted over a total 8 sessions. Pre-post tests of the subjective well-being scale, DAS, multiple life satisfaction scale, ego-resilience scale were conducted and the children then made picture stories during the program itself. The results of the analysis of differences between pre-post tests were as follows: first, the negative emotions of participating children decreased significantly. Second, the school-satisfaction and self-satisfaction levels of the participating children increased. Third the participating children's positive perceptions of self and interpersonal relationships also increased through the forest activities. Finally, there were differences of the change types of picture stories that children created while they were participating in the program; and these divergences were related to the effectiveness of the program. These forest activities had positive effects upon the economically disadvantaged children who participated in this study. However, in order to increase the effects of such forest activities qualitatively, greater support for the active involvement of children is required.
