가상 현실 세계에서 정보교류의 수단으로 자신의 정보를 제공하거나 또다른 정보를 수집하는 등의 정보교류와 자신을 표현하고자 하는데에 기존의 2차원의 캐릭터보다는 3차원의 캐릭터를 이용하여 사용자의 대리인으로 분신(Avatar)을 사용하는 3차원 영상을 주제로 하는 많을 연구들이 진행되고 있다. 본 연구에서는 가상현실 세계에서의 분신이 좀 더 현실감이 있는 자연스러운 행동과 상호작용을 보이기 위해서 사람 모습을 닮은 분신을 연구하였으며, 실세계의 자연스러운 정보들(손 동작, 몸 동작)을 분신에 적용하여 가상세계에서 분신의 행동양식과 상호작용이 가능하고 시각, 청각, 역각등의 다중형태의 정보들을 3차원으로 제공하고자 하는데 중점을 두었다. 이 시스템은 가상세계에서 분신을 생성하며 몇가지의 기본 행동을 가지고 간단한 방법과 실시간으로 분신의 움직임을 처리 할 수 있는 분신의 행동양식과 상호작용이 가능한 하가지 시스템을 소개할 것이다. 또한 이 시스템은 다른 기종의 플랫폼(PC, W/S)간에 다중참여자를 위하여 네트윅 환경하에서 실행 될 수 있다.

본 논문에서는 생물의 2차원영상에서 4가지의 특징을 추출한 다음 약품에 대한 생물의 행동 패턴 반응에 대하여 의사결정나무를 적용하여 패턴의 인식 및 분류를 하였다. 생물의 행동패턴을 대변하는 물리적인 특징인 속도, 방향전환 각도, 이동거리에 대하여 각각 중간이상속도비율, FFT(Fast Fourier Transformation), 2차원 히스토그램 면적, 프렉탈, 무게중심을 사용하여 특징을 추출하였다. 이렇게 추출된 4가지의 특징변수들을 사용하여 의사결정나무 모델을 구성한 다음 생물의 약품 첨가에 대한 반응을 분석하였다. 또한 결과에서는 기존의 생물의 행동패턴 구분에 쓰였던 전형적인 기법(conventional methods)보다 본 연구에서 적용한 의사결정나무가 생물의 행동패턴이 가지는 물리적 요소에 대한 독해력을 가짐을 보임으로써 특정환경에서 이동행동에 대한 분석을 용이하게 하고자 하였다.

The primary purpose of this research is to develop and test a model that explains the process of how multidimensional trust in a supplier firm and salesperson through relational commitment influence buyer's relational citizenship behavior. The proposed framework uses a multidimensional conceptualization for the trustworthiness construct such as benevolence and credibility and incorporates two distinct facets of consumer trust, namely, organization trust, and salesperson trust. The authors test the proposed model using data from MD in buying finns.. The tests show the differential effect of trust dimensions on relational commitment and citizenship behavior. The authors discuss the implications of the findings for trust-commitment theory and practice.

The researchers of the organizational behavior have been interested in the performances of transformational leadership in various environments and cultures. In this study, data were collected to find out the effects of professors' transformational leadership on students’ departmental identification, study engagement and organizational citizenship behavior to school. This study also tested indirect effect between transformational leadership and organizational citizenship behavior via departmental identification and study engagement. The results indicated significant direct relation between professors' transformational leadership and departmental identification, study engagement and citizenship behavior to school. But direct relation between study engagement and citizenship behavior was not found. Departmental identification was found as a mediator between transformational leadership and citizenship behavior. This study suggests that professors' transformational leadership is quite necessary for school, department and student.

Behavior awareness is a technology that recognizes human behavior through data and can be used in applications such as risk behavior through video surveillance systems. Conventional behavior recognition algorithms have been performed using the 2D camera image device or multi-mode sensor or multi-view or 3D equipment. When two-dimensional data was used, the recognition rate was low in the behavior recognition of the three-dimensional space, and other methods were difficult due to the complicated equipment configuration and the expensive additional equipment. In this paper, we propose a method of recognizing human behavior using only CCTV images without additional equipment using only RGB and depth information. First, the skeleton extraction algorithm is applied to extract points of joints and body parts. We apply the equations to transform the vector including the displacement vector and the relational vector, and study the continuous vector data through the RNN model. As a result of applying the learned model to various data sets and confirming the accuracy of the behavior recognition, the performance similar to that of the existing algorithm using the 3D information can be verified only by the 2D information.

Behavioral sequences of the medaka(Oryzias latipes) were investigated through an image system in response to medaka treated with the insecticide and medaka not treated with the insecticide, diazinon(0.1 mg/1). After much observation, behavioral patterns could be divided into 4 patterns: active smooth, active shaking, inactive smooth, and inactive shaking. These patterns were analyzed by 5 features: speed ratio, x and y axes projection, FFT to angle transition, fractal dimension, and center of mass. Each pattern was classified using decision tree. It provide a natural way to incorporate prior knowledge from human experts in fish behavior, The main focus of this study was to determine whether the decision tree could be useful in interpreting and classifying behavior patterns of the animal.

This study utilized one of Hofstede's cultural dimension, collective dimension and validated its influence on individual's change oriented organizational citizenship behavior(COCB hereafter) with mediation of emotional regulation. Previous research on Hofstede's cultural dimensions were mostly conducted at national levels. However, in this study, Yoo's CVSCALE was used to analyze collectivistic tendencies at individual levels and its influence on emotional regulation and COCB were measured. The study distributed 200 paper based self administered surveys to employees of Fortune 500 electronic company in Korea for two weeks period. Findings indicated individual's collectivistic dimension positively influenced COCB and emotional regulation mediated between collectivism and COCB. In conclusion and application, the significance of this research lies in indicating collectivistic culture's positive influence on COCB and emotional regulation as possible antecedents of Change oriented Organizational Citizenship Behavior.

This paper aims to confirm the effect of self-control and organization-control on information security attitude. The research method is composed of a cross-design of locus of control and tightness culture. The measurement variables used in the assessment are information security actual attitude, compliace behavioral attitude, and information security efficacy. As a result, the locus of control had a significant effect on information security actual attitude, information security efficacy, information security efficacy, and it was found that influence of the internal-based condition was greater than the external-based condition. The tightness culture had a significant effect on compliace behavioral attitude, information security efficacy, and it was found that influence of the tight culture-based condition was greater than the loose culture-based condition. In addition, the discussion contatins the implications of information security direction that reflect these research results.
