This paper proposes an environment monitoring algorithm using a behavior-based multiple robot system. This paper handles an escort and a boundary-tracking especially. Unlike previous research works, the proposed environment monitoring system which is based on the behavior-based multiple robot control allows the system to employ the reusable code and general algorithm. Also, the proposed method can be applied to cheaper process with low performances. In the proposed method, escort and boundary-tracking missions are constructed by weighted sum of predefined basic behaviors after redefining the basic behaviors in previous works and introducing the novel basic behavior. Simulation results of the proposed method are included to demonstrate the practical application of the proposed algorithm.

Autonomous mobile robots are required to achieve multiple goals while responding quickly to the dynamic environments. An appropriate robot control architecture, which clearly and systematically defines the relationship among the inputs, the processing functions and the outputs, thus needs to be embedded in the robot controller. This paper proposes a kind of hybrid control architecture which combines the key features of the two well-known robot control architectures; hierarchical and behavioral- based. The overall control architecture consists of three layers, i.e. the highest planner, the middle plan executor, and the lowest monitor and behavior-based controller. In the planned situation, only one behavior module is chosen by the logical coordinator in the plan executor according to the way point bin. In the exceptional situation, the central controller in the plan executor issues an additional control command to reach the planned way point. Several simulations and experiments with autonomous mobile robot show that the proposed architecture enables the robot controller to achieve the multiple sequential goals even in dynamic and uncertain environments.

The purpose of this study was to examine the mediating effect of moral disengagement concerning the parental psychological control on children's participant role behavior in bullying situations. For the purposes of this research, a group of participants comprising total 541 students of fifth, seventh, eighth, tenth and eleventh grades from schools based in Seoul and Incheon were surveyed. As far as research methods are concerned, scales for parental psychological control, moral disengagement and participant role behavior in a bullying situation were used. The main findings of this research were as follows. First, by gender, there was a significant difference in participant role behavior in bullying. By grade, a significant difference was shown in parental psychological control, participant role behavior in bullying and moral disengagement. Second, variables affecting participant role behavior in bullying situations were found to be influenced by the types of role behavior respectively as well as by students' grade levels. Third, moral disengagement concerning the influence of parental psychological control on participant role behavior was found to have a full mediating effect on bystander behavior among elementary school students and bullying behavior among middle school and high school students.

Navigation in environments that are densely cluttered with obstacles is still a challenge for Autonomous Ground Vehicles (AGVs), especially when the configuration of obstacles is not known a priori. Reactive local navigation schemes that tightly couple the robot actions to the sensor information have proved to be effective in these environments, and because of the environmental uncertainties, STSF(Space and Time Sensor Fusion)-based fuzzy behavior systems have been proposed. Realization of autonomous behavior in mobile robots, using STSF control based on spatial data fusion, requires formulation of rules which are collectively responsible for necessary levels of intelligence. This collection of rules can be conveniently decomposed and efficiently implemented as a hierarchy of fuzzy-behaviors. This paper describes how this can be done using a behavior-based architecture. The approach is motivated by ethological models which suggest hierarchical organizations of behavior. Experimental results show that the proposed method can smoothly and effectively guide a robot through cluttered environments such as dense forests.

The purpose of this study was to test the Theory of Planned Behavior in the prediction of contraceptive behavior among married women. This study used a descriptive correlational design to examine the relationships among the study variables. Eighty married women in Seoul and Kyungki-do participated in this study, Research instruments used were the tool for measuring TPB variables search as attitude toward contraception, subjective norm, perceived behavioral control, and intention ; and the tool for measuring contraceptive behavior. The former was modified by the researcher according to Ajzen & Fishbein(1980)'s guidelines for tool development and Jee (1993)'s tool. The latter was developed by the researcher Data was collected from July 20, 1996 to October 25, 1996. The results are as follows ; The three factors, attitude, subjective norm and perceived behavioral control of contraception can explain 30% of the variance in contraceptive intention. Inspection of path coefficient for each of the three predictor variables revealed that subjective norm and perceived behavioral control were the predictor variables on intention, while attitude was not. ; and intention and percevied behavioral control factors can explain 42% of the variance in contraceptive behavior. Inspection of path coefficient for each of the two predictor variables revealed that intention and perceived behavioral control were the predictor variables on behavior. In conclusion, this study identified that Theory of Planned Behavior was a useful model in the prediction of contraceptive behavior, and the contraceptive service program based on the TPB variables would be an effective nursing intervention for the change in contraceptive behavior.

The purpose of this study was to investigate the effects of health control behaviors on the emotional happiness of the elderly. Among the survey instruments used in this study, emotional hapiness was the tool developed by Watson et al., 1978, and health control behavior was used by tools developed by Wallston et al., in 1988. Health control behaviors consist of three sub-factors: other health control behavior, accidental health control behavior, and internal health control behavior. The data collection period was collected from June 20 to July 5, 2018. A total of 152 participants were enrolled from 65 to 85 years old and were collected from six provinces of Korea (Seoul, Gangwon Province, Gyeongsang Province, Jeolla Province, Chungcheong Province, Gyeonggi Province) as much as possible. As a result of the analysis of demographic characteristics, the number of elderly people couple living was 47.4%, living alone was 21.1%, the number of people living with a couple and their children was 13.8%, the others were 10.5%. Based on the above results, 21.1% were living alone as an elderly person. And people who the highest monthly income of less than 1 million won was 36.8%, the usual meal type, 94.7% were very much eaten with vegetarianism smoking and drinking alcohol, and 94.7% did not smoke and 73.7% drank alcohol. In conclusion, Multiple regression analysis of health control behaviors on emotional happiness showed that health control behaviors had a 15% effect on emotional happiness. The following suggestions were made through the results of this study. First, the monthly income of the elderly is very low to maintain health, Second, the health of elderly people was maintained through friends and meetings. Based on these results, it should be used as a basic data for the program for the emotional happiness of the elderly.

This paper proposes modeling of human behavior and a method of finding irregular human behavior. At first, human behavior model is proposed by paying attention to habitual human behavior at home. Generally, it is difficult to obtain the information of individual life pattern because of high cost for setting sensors such as cameras to observe human action. Therefore we capture turning on/off consumer electronic equipments as actual human behavior action, where some or many consumer electric equipments were used such as television, room light, video and so on in our daily life. Noting that are some relations between turning on/off those consumer electric equipments and our action, we proposes how to construct a human behavior knowledge by analyzing human behavior based on observation of human habitual life. Also an algorithm to identify on find irregular behavior different from habitual life behavior are described. Finally, the significance of the proposed method is shown by some experimental results.

전통적인 모델 기반 제어 방법은 로봇의 센서계로부터 유추한 현 상황과 로봇이 가지고 있는 주변 환경에 대한 모델을 비교하고 이를 토대로 정교한 경로 계획에 따라 로봇을 구동하는 방식이다. 이러한 방식은 로봇의 주변 환경이 바뀌거나 동적으로 변화하는 경우에는 적용하기 어렵기 때문에 미리 알려져 있고 고정되어 있는 환경이 아니면 로봇이 성능을 발휘하기가 어렵다. 이에 반하여 행위기반 제어는 로봇이 처해있는 주변 환경에 대한 모델이나 경로 계획에 의존하지 않고 로봇의 특정한 센서 출력에 대하여 특정한 행위를 즉각적으로 수행하도록 구성되어 있어서 비구조적인 환경이나 동적으로 변화하는 환경에서 로봇에 적용하기가 좋다. 본 논문에서는 로봇이 처한 상황에 따라서 행위를 달리하는 상황의존형 행위기반 제어 구조를 제안하고 이를 1:1 2족 축구 로봇에 적용하여 그 효용성을 보인다.

The primary objectives of this research are to investigate the energy factor response of steel moment resisting frame (MRF) systems equipped with fuses subject to ground motions and to develop an energy-based evaluation approach for evaluating the damage-control behavior of the system. First, the energy factor of steel MRF systems with fuses below the resilience threshold is derived utilizing the energy balance equation considering bilinear oscillators with significant post-yielding stiffness ratio, and the effect of structural nonlinearity on the energy factor is investigated by conducting a parametric study covering a wide range of parameters. A practical transformation approach is also proposed to associate the energy factor of steel MRF systems with fuses with classic design spectra based on elasto-plastic systems. Then, the energy balance is extended to structural systems, and an energy-based procedure for damage-control evaluation is proposed and a damage-control index is also derived. The approach is then applied to two types of steel MRF systems with fuses to explore the applicability for quantifying the damage-control behavior. The rationality of the proposed approach and the accuracy for identifying the damage-control behavior are demonstrated by nonlinear static analyses and incremental dynamic analyses utilizing prototype structures.
