This paper introduces an emotional behavior decision model for intelligent service robots. An emotional model should make different behavior decisions according to the purpose of the robots. We propose an emotional behavior decision model which can change the character of emotional model and make different behavior decisions although the situation and environment remain the same. We defined each emotional element such as reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics by state dynamic equations. The proposed system model is a linear system. If you want to add one external stimulus or behavior, you need to add just one dimensional vector to the matrix of external stimulus or behavior dynamics. The case of removing is same. The change of reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics also follows the same procedure. We implemented the proposed emotional behavior decision model and verified its performance.

This study has performed to identify the effect of safety behavior, safety climate and its satisfaction through the Behavior Based Safety Program for 5 sites of the same Company. The study result indicated that the level of recognized safety behavior, climate and its satisfaction improved by conducting observation of worker behavior, jobsite feedback, displaying feedback chart, safety training, behavior modification committee. Additionally, the participation level of safety activity and conformity level of safety rule improved. The recognized level of safety climate improved together with recognized safety value by management, safety participation of direct boss, communication with each other to be dealt with safety matter, safety training material to be contained unsafe behavior and practical hazard, understanding and conducting safety standard. In addition, The recognized level of satisfaction improved together with safety behavior and climate. As a result, this program provided an opportunities to correct worker's unsafe behavior to safe behavior in conjunction with increasing number of observation, providing additional time to have a safety check, safety suggestion to improve work situation and a permit to work rule. It will be integrated into health and safety management system to be able to reduce industrial accident.

It is necessary to change the existing design process to cope with a short life-cycle product and various customer's demands. Also a frequent design change may delay the whole design process and it will increase the unit cost of the production. New alternatives or techniques have emerged to solve the existing design problems, such as a knowledge based engineering, an intelligent CAD, a function based design, and so on. In this paper, we propose a hybrid design system with a knowledge based design methodology and a function based design technique. The knowledge based design is good at a frequent design change and the function based design is effective to extract a core design behavior. In an early design process, the system utilizes a core design behavior through the function based design process. On the other hand, the system manages complicated design issues with the knowledge based design technique in the detailed design process. We conclude that the hybrid design system can bring fair effects on implementing an efficient design environment in aspect of time and expense.

악성코드 유포자들은 웹 어플리케이션 취약점 공격을 이용해 주로 악성코드를 유포한다. 이러한 공격들은 주로 악성링크를 통해 이루어지며, 이를 탐지하고 분석하는 연구가 활발히 이루어지고 있다. 하지만, 현재의 악성링크 탐지 시스템은 대부분 시그니처 기반이어서 난독화 된 악성링크는 탐지가 거의 불가능하고 알려진 취약점은 백신을 통해 공격을 사전에 방지 할 수 있지만 알려지지 않은 취약점 공격은 사전 방지가 불가능한 실정이다. 이러한 한계점을 극복하기 위해 기존의 시그니처 기반 탐지 방법을 지양하고 행위기반 탐지 시스템에 관한 연구가 이루어지고 있다. 하지만 현재 개발된 탐지 시스템은 현실적으로 제약사항이 많아 실제로 활용하기에는 한계가 있다. 본 논문에서는 이와 같은 한계를 극복하고 탐지 효율을 높일 수 있는 새로운 웹 브라우저 기반 악성행위 탐지 시스템인 WMDS (Web-browser based Malicious behavior Detection System)를 소개 하고자 한다.

Turning behavior of tractor-trailer system was studied to guide the tractor and trailer. Based upon kinematic relationship between the tractor and the trailer, a mathematical model was developed and analyzed by computer simulation. A field test was carried out to verify the mathematical model. Following conclusions were drawn from this study. 1. A mathematical model and a simulation program for turning behavior of tractor-trailer system were developed. 2. The results of the field tests showed that the RMS errors were less than 0.33m and the mathematical model based upon kinematic relationship can be used for mapping guidance system for tractor and trailer. 3. As the steering angle was increased, the turning radius was decreased. When the tractor travelled at the low speed, the travel speed of the tractor did not affect turning radius but did affect running time and stability for steering. 4. When the tractor travelled under the critical velocity, the towed trailer followed smoothly. When the the tractor travelled faster than the critical velocity, the towed trailer oscillated. The critical velocity was determined from the specification of the tractor and the trailer.

This study presents an effective stiffness-based optimal technique to consider floor rigid diaphragm action and a technique to evaluate the structural behavior characteristics and efficiency for tall shear wall outrigger system subject to horizontal loads. To this end, isoparametric plane stress element with rotational stiffness is used for shear wall element and stiffness gradient is calculated. Also, the approximation concept to solve effectively the large scaled problems, member grouping technique and resizing technique are considered. To verify the effectiveness and usefulness of this technique, the efficient evaluation method for three types of 50 story model with core and outrigger system is presented.

절취 사면에서의 파괴는 사면의 내부 또는 외부 요인들의 결합에 의해 발생한다. 내부 요인은 사면 자체의 지질 또는 형상 조건과 관련된 파괴 요인이며, 외부 요인은 자연적 또는 인위적으로 사면에 가해지는 파괴 요인이다. 각 요인에 의한 사면 파괴에 기치는 영향의 정도는 사면을 구성하는 지반 조건에 따라 다르며, 사면의 거동 특성에 의해 제어된다. 이 연구에서는 사면의 지반 조건을 거동 특성에 따라 구분하는 기준으로 토층심도율(SR), 블록크기비(BR) 및 암석강도를 사용하였다. 이런 기준에 의하면 사면의 지반 조건은 불연속체적 절리 암반과 연속체적 토상 지반, 파쇄 암반, 괴상 암반으로 구분된다. SFi-system은 이와 같이 구분된 지반 조건에 따라 내부 파괴 요인과 외부 파괴 요인을 평가함으로써 사면 파괴 지수(SFi)를 결정하는 평가 시스템이다. 이 평가 시스템을 실제적으로 사면에 적용한 결과, 사면 파괴 지수는 사면 파괴의 가능성 및 규모와 밀접한 관련이 있음을 보여준다. 따라서 SFi-system은 사면의 파괴 예측과 그 특성 분석을 위한 효과적인 도구로 사용될 수 있다.

Concurrent behaviors of multithreaded programs cannot be described effectively by automata-based models. Thus, concurrent program intrusion attempts cannot be detected. To address this problem, we proposed the process algebra-based detection model for multithreaded programs (PADMP). We generate process expressions by static binary code analysis. We then add concurrency operators to process expressions and propose a model construction algorithm based on process algebra. We also present a definition of process equivalence and behavior detection rules. Experiments demonstrate that the proposed method can accurately detect errors in multithreaded programs and has linear space-time complexity. The proposed method provides effective support for concurrent behavior modeling and detection.

Purpose: The descriptive correlational study was designed to examine the relationship of eating behavior to depression, trait anger, anger expression, Behavior Activation System(BAS) and Behavior Inhibition System(BIS) in adolescent women. Method: 437 women aged 15 to 18 years were recruited from two high schools located in Seoul, Korea. The instruments used were SCL's depression scale, Spielberger's state trait anger expression inventory-Korean version for trait anger and anger expression, the Korean-BAS/BIS scale for behavior activation system and behavior inhibition system, and Eating Attitude Test(EAT-26) for eating behavior. Results: The score of EAT significantly correlated with depression, trait anger, anger expression, BAS and BIS. The EAT score also had a significant relationship with anger-in and anger-out. Depression only correlated with the dieting among factors of EAT, Trait anger, anger-in and anger-out showed a significant correlation with EAT factors such as dieting and oral control. BAS significantly correlated with dieting; whereas, BIS revealed a relationship with bulimia/food preoccupation. Conclusion: Based on this results, various variables need to be included for a nursing intervention program leading to healthy diet behaviors of adolescent women.
