Purpose: The purpose of this study was to construct a questionnaire to assess male workers' sobriety behavior based on Ajzen's Theory of Planned Behavior (TPB). Methods: A primary questionnaire with 56 questions was constructed based on literature review and structured interview with male workers. The Content Validity Index (CVI) was evaluated by a group of experts, construct validity was tested by principle component analysis, and reliability was evaluated by Cronbach's ${\alpha}$ and the test-retest reliability test. Results: Fifty two questions showed higher than .8 of CVI. Four factors explained 78.71% of the total variance among items for sobriety intention and direct measure, and six factors explained 67.99% of the total variance among indirect measure items and those factors coincided with the variables of TPB in factor analysis. Cronbach's ${\alpha}$ of this questionnaire was .873 and the result of test-retest reliabilty test was relatively reliable. A total of 41 items with 7-point scale were constructed in the final version. Conclusion: This questionnaire was valid and reliable to measure sobriety behavior based on TPB in male workers. It can be useful to evaluate the result of a sobriety program for male workers.

웹은 지금까지 연구되어온 전통적인 정보검색 시스템과는 차별되는 새로운 정보환경이므로 웹상에서 발생하는 이용자와 정보검색 시스템 간의 상호작용에 대한 이해를 위해 새로운 관점에서의 연구가 충분히 이루어져야 하며 이러한 연구를 뒷받침해줄 웹 기반 정보탐색 패러다임이 정착될 필요가 있다. 이러한 맥락에서 본 연구는 웹 정보탐색행위를 연구한 문헌에서 제시된 이론적 모형들을 검토하고 비교 분석하였다. Wang, Hawk, Tenopir, Hsieh-Yee, Choo, Detlor, Turnbul, Chun과 Cooper, Rieh, Spink의 연구에서 제시된 모형들이 논의되었다. 분석 결과, 웹 정보탐색 모형은 크게 상호작용 모형, 정보탐색행위 모형, 평가 모형으로 구분되며, 전통적인 정보탐색과정 모형에 비해 복합요인들의 상호작용과 정보탐색행위의 비선형적 관점이 강조되었다는 특징을 갖는다.

A Study on the make-up expression and purchasing behavior of make-up cosmetics based on the lifestyle. The intention of this study is to classily the consumer group based on the lifestyle, to research the characteristics and desire of the each group, and to find out the differences of the make-up expression and purchasing behavior of make-up cosmetics among each group. The result of this study are as follow; 1. We have obtained seven factors out of twenty six lifestyle items by using AIO lifestyle measurement. The seven factors are make-up high involvement factor, brand loyal factor, make-up bases factor, economical and natural beauty oriented factor, impulsive consumption oriented factor, stubborn choice factor, sensitive to others view factor 2. We have formed four groups based on the seven factors. The four groups are impulsive consumption type, professional make-up type, intentional make-up type, basic type. 3. It was examined that women want to express smart, ellegant and intelligent images form the make-up 4. According to the examination of the differences of the purchsing behavior, only the purchase motive, information source and cosmetics purchase amount per month was differentiate among the groups.

프로그램 행위기반 침입탐지 기법은 데몬 프로그램이나 루트 권한으로 실행되는 프로그램이 발생시키는 시스템 호출들을 분석하고 프로그램 행위 프로파일을 구축하여 잠재적인 공격을 효과적으로 탐지한다. 그러나 각 프로그램마다 매우 큰 프로파일이 구축되어야 하는 문제점이 있다. 본 논문은 프로파일의 크기를 줄이기 위해, 프로그램 행위 프로파일링 및 이상행위 탐지에 X$^2$ 거리기반 다변량 분석 기법을 응용하였다. 실험 결과, 프로파일을 비교적 작게 유지하면서 탐지율에서는 의미있는 결과를 보였다.

Purpose: This research aims to find out clinical information protection behavior within a medical institution in mandatory circumstance based on health psychology theories Methods: This research has developed the survey based on the variables from ealth psychology theories; and conducted the survey during the whole month in April 2013. In the end, 256 samples have been used for this research's analysis. Results: First of all, Empirical results has proved that perceived benefits, self-efficacy, and cues to action have an positive influence on clinical information protection behavior. Perceived barriers has an negative influence. Finally, it has proven from the research that perceived severity and perceived susceptibility do not have an impact on clinical inf ormation protection behavior Conclusion: These findings provide an enriched understanding about medical institution workers information protection behavior on patient's clinical information.

In this paper, we propose a fast and robust algorithm for fighting behavior detection based on Motion Vectors (MV), in order to solve the problem of low speed and weak robustness in traditional fighting behavior detection. Firstly, we analyze the characteristics of fighting scenes and activities, and then use motion estimation algorithm based on block-matching to calculate MV of motion regions. Secondly, we extract features from magnitudes and directions of MV, and normalize these features by using Joint Gaussian Membership Function, and then fuse these features by using weighted arithmetic average method. Finally, we present the conception of Average Maximum Violence Index (AMVI) to judge the fighting behavior in surveillance scenes. Experiments show that the new algorithm achieves high speed and strong robustness for fighting behavior detection in surveillance scenes.

Ultra High Performance Fiber Reinforced Concrete (UHPFRC) has a outstanding tensile hardening behaviour after a crack develops, which gives ductility to structures. Existing shear strength model for fiber reinforced concrete is entirely based on crack opening behavior(mode I) which comes from flexural-shear failure, not considering shear-slip behavior(mode II). To find out the mode I and mode II behavior on a crack in UHPFRC simultaneously, maximum shear strength of cracked UHPFRC is investigated from twenty-four push-off test results. The shear stress on a crack is derived as variable of initial crack width and fiber volume ratio. Test results show that shear slippage is proportional to crack opening, which leads to relationship between shear transfer strength and crack width. Based on the test results a hypothesis is proposed for the physical mechanics of shear transfer in UHPFRC by tensile hardening behavior in stead of aggregate interlocking in reinforced concrete. Shear transfer strength based on tensile hardening behavior in UHPFRC is suggested and this suggestion was verified by comparing direct tensile test results and push-off test results.

Groundwater flow and behavior have to be investigated based on heterogeneous subsurface formation since the homogeneity assumption of this formation is not valid. Over the past twenty years, stochastic approach and Monte Carlo technique have been utilized very efficiently to understand the groundwater flow behavior. However, these techniques require lots of computational and numerical efforts according to the various researchers' comments. Therefore, utilizing new techniques with much less computational efforts such as Artificial Neural Network (ANN) in the prediction of the stochastic behavior for the groundwater based on heterogeneous subsurface formation is highly appreciated. The current paper introduces the ANN technique to investigate and predict the stochastic behavior of a well draw down in a confined aquifer based on subsurface heterogeneous hydraulic conductivity. Several ANN models are developed in this research to predict the unsteady two dimensional well draw down and its stochastic characteristics in a confined aquifer. The results of this study showed that ANN method with less computational efforts was very efficiently capable of simulating and predicting the stochastic behavior of the well draw down resulted from the continuous constant pumping in the middle of a confined aquifer with subsurface heterogeneous hydraulic conductivity.

We have proposed modeling methods of mariners' standard behavior for collision avoidance by analyzing mariners' recognition process in a previous study. As a subsequent study, the aim of this study is to build a model of mariners' execution process which is one of six processes in the condition of collision avoidance. In this study, thus, the structure of mariners' information processing on the process of taking avoiding actions is described and the relation between mariners' behavior and necessary factors in the process is analyzed. And then we have built a model of mariners' standard behavior for execution process based on the characteristics of mariners in ship-handling, which are obtained from the international collaborative research on human factors. It is tried to define the contents of execution process based on the standard behavior of mariners for collision avoidance and to formulate information processing of mariners.
