프레임(Key Frame) 애니메이션 방법은 많은 수의 개체들을 동시에 움직여야 하는 애니메이션을 수행 시에 이를 모두 수작업을 통해서 움직여야 하는 단점이 있다. 본 논문에서는 이러한 단점을 보완하기 위해서 행동기반 그룹 애니메이션에 대하여 연구하였다. 이를 위하여 애니메이션되는 각각의 개체에 자신의 내적 상태와 외부의 환경에 의해서 영향을 받아서 다음에 취해야 할 행동을 확장 가능한 구조로 설계된 행동구조(Behavior Architecture)에 이미 프로그램 되어 있는 모듈을 삽입하였다. 그리고 이에 따라서 판단하고 수행될 수 있도록 한 후에, 각각의 개체가 자신의 고유한 행동을 취해서 움직이면서도 그룹의 특성을 가지는 행동을 수행할 수 있도록 구현하였다.

본 연구의 목적은 노년층 남성과 여성의 인구통계적 특성이 의복태도, 의복행동, 쇼핑행동에 미치는 영향을 규명하는 것이다. 설문지를 통하여 나이 55세 이상의 미국 남부에 거주하는 67명의 남성과 75명의 여성이 자료분석에 이용되었다. 의복 및 쇼핑과 관련된 변수로 의복태도, 유행의사 선도력, 기성복에 대한 만족, 쇼핑관심, 점포충성도가 사용되었으며, 인구통계적 특성은 수입, 결혼여부, 사회참여도, 학력, 나이, 성으로 구성되었다. 결과로 의복태도는 미혼일수록, 사회참여도가 높을수록, 학력이 높을수록 그 수치가 높은 것으로 낱났다. 기성복에 대한 만족은 수입과 학ㄱ력이 높을수록 또 남성이 여성에 비해 만족도가 큰 것으로 나타났다. 쇼핑에 대한 관심의 정도는 결혼여부, 학력, 성과 관련이 있었다. 즉 미혼일수록 교육수준이 높을수록 남성보다는 여성이 쇼핑에 관심이 큰 것으로 나타났다. 그 외 유해의사선도력은 오직 성에 의해서만 영향을 받았으며, 점포충성도 역시 학력에 의해서만 영향을 받았다. 남성과 여성 각각의 차이에 대한 분석에서는 남녀에 따라 인구통계적 특성이 의복태도, 의복행동, 쇼핑행동에 미치는 영향이 다르게 나타나 남녀간의 차이를 보여주었다. 예로 남성에게 있어 결혼여부는 쇼핑관심에 영향을 미치는 중요 변수이나 여성의 경우 교육수준이 쇼핑관심에 영향을 미치는 것으로 나타났다. 따라서 유통업 종사자들은 노년층 남성 중 미혼자를, 노년층 여성 중 고학력자를 주요 표적으로 삼아 마케팅 전략을 세울 필요가 있다 하겠다.

This study was conducted to examine whether hasty behaviors were structurally maintained even after the expansion of age zones and to determine the characteristics of hasty behaviors by gender and age. To this end, an analysis was made of the data of 591 respondents after excluding the insincere respondents from the 602 adults who had replied to the survey on hasty behaviors. Its results showed that a hasty behavior consisted of 5 factors regardless of age. Even when age was expanded, a hasty behavior maintained its structural stability. On the other hand, women were higher than men in the average score of hasty behaviors. Lastly, hasty behaviors decreased with the increase in age. The gender differences in hasty behaviors were analyzed on the basis of those in time pressure perception and task processing method. They were presented to show that the speed reduction by age increase is related to psychological mechanism as well as bodily function.

This study examined the influence of social support (social support from family, social support from friends), psychological behavioral characteristics (self-esteem, interpersonal dependency, locus of control), and stress on the depression levels of college students. The study subjects were 546 college students in D city. The survey was conducted using a self-administered questionnaire in October 2015. As a result, the depression levels were significantly higher in the group showing lower family and friends' social support, self-esteem, and locus of control, while it was significantly higher in the group showing higher interpersonal dependency and stress. The depression levels of the subjects showed a negative correlation with family and friends' social support, self-esteem, and locus of control, but a positive correlation with interpersonal dependency and stress. Covariance structure analysis revealed an increase in the depression levels of college students when the awareness of the stress source was higher, and when the awareness of social support or psychological behavioral characteristics was lower. These results suggest that the depression levels of college students would be increased when the social support and psychological behavioral characteristics are low, and when stress is high. In particular, it was influenced much more by stress than other factors. Therefore, to decrease the depression levels of college students, it would be necessary to put efforts to understand their main stress sources and then reduce them.

This study aims to empirically analyze the effects of the learning organization characteristics in public libraries on the innovative work behavior of librarians. In this analysis, 113 librarians from 15 public libraries in the Seoul Metropolitan Area of South Korea were surveyed to investigate the learning organization characteristics of libraries and innovative work behavior. Through a multiple regression analysis of learning organization characteristics and innovative work behavior, it was found that, among the sub-factors of learning organization characteristics, creating continuous learning opportunities and creating systems to capture and share learning had a positive effect on idea realization among the sub-factors of innovative work behavior. From this, it was interpreted that public libraries should increase financial and non-financial support for librarians to learn and also that libraries should create various systems such as electronic bulletin boards and meetings in which librarians can share their learning. Moreover, the sub-factors of learning organization characteristics were found to have no effect on idea generation and idea promotion among the sub-factors of innovative work behavior, which indicated that it will be necessary to identify the organization characteristics that affect idea generation and idea promotion. This study is significant in that it identified the sub-factors of learning organization characteristics that promote the innovative work behavior of public library librarians.

최근 딥러닝을 통하여 영상의 카테고리 분류를 응용한 행동 인식이 활발히 연구되고 있다. 그러나 행동 인식을 위한 기존 연구 방법은 높은 수준의 하드웨어 사양을 요구하며 행동 인식에 대한 학습에 많은 시간이 소모되는 문제점을 지니고 있다. 또한, 행동 인식 테스트 결과를 얻기 위해 많은 시간이 소모되며 딥러닝 특성상 적은 수의 학습 데이터는 overfitting 문제를 일으킨다. 본 연구에서는 이러한 문제점을 해결하고자 행동인식을 위한 학습시간과 테스트 시간 감소를 위해 미리 학습된 VGG 모델을 사용해 얻어낸 RGB 데이터의 특징만을 학습에 사용하고 적은 수의 데이터로 행동 인식 테스트 결과를 높이기 위하여 RGB 데이터 증대를 통해 기존의 행동인식 연구보다 학습시간과 행동인식 테스트에 소모되는 시간을 줄인 방법을 행동 인식에 적용하였다. 이 방법을 UCF50 Dataset 에 적용하여 98.13%의 행동인식에 관한 정확성을 확인하였다.

The authors intended to investigate personality characteristics and those influence on the outcome of cognitive behavioral therapy in patients with panic disorder. 167 patients who met DSM-IV criteria for panic disorder were assessed by the PDQ-R(Personality Disorder Questionnaire-Revision) and various self-report tools for assessing symptoms of panic disorder. The effect of therapy was measured by the changes of scores and the end state functioning before and after 12-sessions of CBT. The patients with panic disorder were more likely showed obsessive-compulsive, avoidant and paranoid personality disorder and also Cluster C. If is needed when patients were divided into two groups according to total scores of PDQ-R(high or low personality disorder groups), high personality disorder group showed many evidences for increased psychopathology at the start of treatments, this suggested the close linkage between panic disorder and personality disorder. Interestingly, there were no significant differences between both groups in scores of clinical variables and the end state functioning. In conclusion, although patients with high tendency of personality disorder had more generalized problems at the beginning of treatments, they could improve as much as the patients with low tendency of personality disorder. They can be helped by cognitive behavioral therapy for panic disorder and seem to profit as much as patients with low tendency of personality disorder. If is needed to seek other factors in poor responders for cognitive behavioral therapy.
