본 연구의 목적은 선박조종시뮬레이터(Ship Handling Simulator)를 이용하여 해기사 SRK(Skill-, Rule-, Knowledge) 기반 행동 측정을 하고자 하는 것이다. SRK 행동은 Rasmussen에 의해 제안된 행동 이론이며, 인적오류로 인한 사고는 매년 발생하고 있고, 인적오류로 인한 해양사고를 줄이고자 하는 연구가 필요하다. 우선 해기사 SRK 행동을 정의하고, 선박조종시뮬레이터를 이용하고 다양한 시나리오를 통해 해양사고 중 충돌상황에 대하여 측정 방법을 연구하고자 한다.

인적오류에 인한 사고는 매년 발생 중이고, 인적오류에 의한 해양사고는 과학적인 인적오류모델을 통해서 해결방안을 모색할 수 있다. 본 연구의 목적은 선박조종시뮬레이터를 이용하여 해기사의 SRK(Skill, Rule, Knowledge) 행동을 식별하기 위한 것이다. SRK 행동은 라스무센이 제안한 행동 이론으로, 본 연구에서는 주어진 상황에 대해서 해기사들이 나타내는 성공 또는 실패 행동을 식별하는데 적용하였다. 식별한 해기사들의 SRK 행동은 인적오류모델의 변수로 적용할 예정이다. 이에, 본 논문에서는 하나의 선행 연구로서 해기사들의 SRK 행동을 선박조종시뮬레이터를 이용하여 측정하는 방법과 측정에 필요한 도구 및 지금까지의 연구결과를 고찰하였다.

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.

Many of the theoretical studies have considered herd behavior as a source of the volatility in financial markets, but there have been few empirical studies on the dynamic herding due to the technical difficulty of detecting herd behavior with time-series data. In this context, this paper proposes a new method for measuring time-varying herd behavior based on QR-GARCH model. Using daily data of KOSPI stocks, this paper provides some empirical evidence for strong and volatile herding among traders of stocks of medium firms, and shows that time-varying herd behavior in traders of some stocks has persistent autocorrelation.

The purpose of this research was to develop a new instrument for nurses' risk behavior related to needlestick injuries and to establish initial evidence of reliability and validity. Twenty five items of the Needlestick Injuries Risk Behavior (NIRB) scale was developed on the basis of the unsafe act theory(Reason, 1990). Such six dimensions as risk behavior on needle recapping, risk behavior using needle on transferring blood sample, risk behavior on separation of needle from syringe, risk behavior on the use of needle, risk behavior when needle is discarded, and risk behavior before the use of needle were described, based on the factor analysis. The study findings initially supported the NIRB's reliability, and construct and criterion validity.

The present study aimed to investigate the discrimination between employee voice and silence behavior in measurement: it is silence behavior the absence of voice or not? It was examined using confirmatory factor analysis. Five measurement models based on the suggestion of Pinder & Harlos(2001) and Van Dyne, Ang, & Botero(2003) were compared. Additionally, the hierarchical multiple regression analysis was conducted for examining the incremental validity of silence behaviors over voice. A total of 204 employees who worked with their own supervisor were surveyed. Results indicated that silence behavior could be a separate construct from voice. Findings also showed that silence behaviors could be distinguished by the level of concreteness in definition, difference in content of motivation and have the incremental validity over voice in only acquiescent Silence. From these results, the theoretical implications of findings, limitations, suggestions for future research were discussed in discussion.

The purpose of this study is to see how young children's playfulness and ability to creatively problem solve can affect their behavior. young children's playfulness in creases with in creasing creativity and personality traits and behavioral problems decrease with increasing of playfulness. Young children's behavioral problems increase with increasing of creative personality traits. In addition, young children's playfulness and creative personality characteristics affect their behavioral problems. The impact on the behavioral problems with variables for playfulness and creative personality traits has a negative correlation with creative curiosity, a sense of humor and expression of fun. The cognitive and physical spontaneity of the playfulness are correlated positively to young children's behavioral problems.

This study was designed to develop a positive behavior support model for children in child care institutions. For this purpose, a demand survey for PBS was conducted with 55 child care institution staff members. 76% of the respondents responded that PBS is needed to prevent problem behavior and can be a good alternative for personality education, and approximately 70% responded that they are willing to implement PBS. The specifications of the model are suggested as follows. First, the preparation step would consist of establishing a support team, educating staff members about PBS, selecting expected behaviors, assessing the current baseline behavior, and setting up a universal PBS environment. The application step would consist of instructing social skills, implementing reinforcement, personal goal-setting and assessing behavior, educating trouble-making students, and monitoring. Finally, at the outcome assessment period, measuring the change in target behavior from the pre-intervention to the post-intervention stage, change in social skills and academic achievement, and social validity is suggested. It is expected that application of this model to children in child care institution will decrease problem behaviors of students, enhance desirable behaviors, and boost the staff members' efficacy.

The objective of this study is to divide the classroom behaviors into the obstacle behaviors in the classroom and the participation behaviors in the classroom for improvement of classroom behaviors upon the subjects of 4th graders of elementary school, and to find out what effects the self-monitoring program influences onto classroom obstacle behaviors and classroom participation behaviors of the subjective children. Study problems established in order to achieve this objective of study are to find out: first, what effects the self-monitoring program influences classroom obstacle behaviors of children, and second, what effects the self-monitoring program influences classroom participation behaviors of children. The subjects of this study are 12 children of a normal classroom of 4th grade of A elementary school located in J city of Jeollabuk-do, out of which 8 children, who showed high proportion in the classroom obstacle behaviors, and 8 children, who showed low proportion in the classroom participation behaviors were selected, and 4 children were those who belonged to both groups resultantly in accordance with the behavior scales measured during the baseline period. To summarize the results obtained through this study, first, the self-monitoring program turned out to influence positive effects upon reduction in the classroom obstacle behaviors of children and retention of their changed behaviors; second, the self-monitoring program turned out to influence positive effects upon increase in the classroom participation behaviors of children and retention of their changed behaviors.

Objective : The purpose of this study was to determine the reliability of Test of Playfulness (ToP) in Attention Deficit Hyperactivity Disorder (ADHD) children. Methods : Twenty ADHD children participated in this study. To determine inter-rater reliability, two raters was evaluated by Test of Playfulness scores and analyzed Kappa coefficient and total agreement and intraclass correlation coefficient (ICC). Results : Total agreement was the range of 75%~95% and the Kappa coefficients was the range of. 45~1.00. Analyzing inter-rater reliability by ICC showed very high reliability: Intrinsic motivation was .96, internal control was .98, suspension of reality was .90, framing was .98, total score was .99. Conclusion : A reliability of Test of Playflness of children with ADHD showed that high. On the basis of this study, it will provide availability for clinical evaluation of children with ADHD, and basic study on the play of children with ADHD.
