  • Distributed applications are composed of multiple nodes, which exchange information with individual nodes through message passing. Compared with traditional applications, distributed applications have more complex behavior patterns because a large number of interactions and concurrent behaviors exist among their distributed nodes. Thus, it is difficult to detect anomalous behaviors and determine the location and scope of abnormal nodes, and some attacks and misuse cannot be detected. To address this problem, we introduce a method for detecting anomalous behaviors based on process algebra. We specify the architecture of the behavior detection model and the detection algorithm. The anomalous behavior detection and analysis demonstrate that our method is a good discriminator between normal and anomalous behavior characteristics of distributed applications. Performance evaluation shows that the proposed method enhances efficiency without security degradation.

  • The purpose of this study was to examine the relation of middle school students' stress in relation to certain variables, those of grade, gender, academic achievement, coping behavior and self-concept. The subjects were 574 students selected from 4 middle schools in the Incheon area. The instruments included a stress index, coping behavior questionnaire and self-concept inventory. The statistics used from this data were t-test, one-way ANOVA (Scheff test), correlation analysis and multiple regression analysis. This study showed that middle school students' stress was influenced significantly by the grade, gender and achievement in school. Also, coping behavior and self-concept were influenced significantly by the grade, gender, and achievement in school. Correlation analysis indicated that student's stress and certain coping behavior were postively correlated, especially avoidance coping behavior indicated a higher correlation to students' stress than active coping behavior. The relationship between stress and self-concept indicated a negative high correlation. It was also found that avoidance coping behavior, family self-concept, general self-concept, school and class self-concept, grade and academic achievement were significant predictors of middle school students' stress.

  • The purpose of this study was to provide basic information on the development of nutrition education programs to improve the mealtime behavior of children with autism spectrum disorder (ASD) by investigating the mealtime behavior and food preferences of children with ASD through the perception of special education teachers. Surveys were given to 108 special education teachers in special education schools in Korea regarding the demographic characteristics, nutrition education support needs, mealtime behavior, and food preferences of children with ASD. Most of the special education teachers responded that nutrition education in special schools had not been conducted properly and nutrition education for ASD children is necessary. Mealtime behavior analysis classified the behavior into three clusters: cluster 1, 'less problematic mealtime behavior'; cluster 2, 'general feature of autism'; cluster 3, 'difficulty in self-directed diet'. The age, eating habits, and food preferences were different according to each mealtime behavior cluster. Therefore, it will be necessary to develop a nutrition education program based on the characteristics of mealtime behavior.

  • The study to be presented related on initial behavior of quench concerned with many considerations, such as epoxy impregnated coil, critical current density related on strain and temperature, winding effect and behavior of internal superconducting wire. Especially, the deformation behavior of coils under magnetic field and thermal contractions at cryogenic temperatures to be dealt with the analytical method related on Fracture Mechanics. From the results, we know that the strain by self weight contribute to epoxy cracking at the edge of deformed coils and the deformation behavior relate on epoxy cracking must be dealt with biaxial loading problem. Then, the epoxy crack on $r\theta-plane$ under biaxial loading have been propagated with inclined crack angle and joined superconducting wire. Also, we can explain transfer of epoxy crack propagation energy from epoxy resin to superconducting wire.

  • The purpose of this study was to examine the mediating role of attitude, subjective norm, and perceived behavioral control on the relationships between past behavior and customers' intention to engage in voice of dissatisfaction responses. Results of the study demonstrated that the inclusion of past behavior improved the predictability of the voice of dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by mediator. In the contests of voice behavior, the effect of past behavior on intention was not mediated by attitude and perceived behavioral control. Meanwhile, subjective norm mediated the relationship between past behavior and the intention to engage in voice behavior.

  • The conditions to simulate the atmospheric corrosion behavior in the laboratory were investigated to clarify atmospheric corrosion mechanism of steel material in coastal area, For airborne sea salt and artificial seawater droplet, the various behaviors were observed by optical microscope, The particle size of the dried airborne sea salt was about $20{\mu}m$, and was about 1/10 compared with the artificial seawater droplet. Though the airborne sea salt represented the same behavior as the thermodynamic water absorption, the behavior of the artificial seawater droplet deviated from the results of the thermodynamic calculation, It is concluded that the water absorption behavior is influenced by the particle size of the dried sea salt. The corrosion behaviors of carbon steels were observed under the deposited condition of airborne sea salt and artificial seawater droplet. The corrosion behaviors showed a different trend, indicating that the corrosion behavior depended on the particle size of the dried sea salt. The corrosion in the actual environrnent progressed greater than that in the chamber. Furthermore, the summer showed the greater corrosion than the spring. It is found that the corrosion behaviors are attributed to the influence of the environmental factors.

  • This study highlights the theme of human error of train drivers, conducting empirical analysis on the relationship between emergency stress, psychological fatigue, safety behavior, and accident. The hypothetical test results based on questionnaires received from 223 train drivers working at A subway firm indicate that emergency stress shows a significant positive effect on psychological fatigue, which in turn shows a significant negative influence on safety behavior. And safety behavior is shown having a significant negative relationship with accident. These results suggest the necessity of corporate-level approaches to depict the drastic causes of drivers' emergency stress, and to effectively manage this stress, as well as the necessity of making effort to enhance safety behavior, and to prevent or reduce accidents.

  • Domestic fowl still tend to exhibit very similar behavior such as perching, nesting and dust-bathing to their ancestor, Red Jungle Fowl (Gallus gallus), even though they have been domesticated for 8,000 years. If given the opportunity, they choose high place for staying at night, a dark place for laying eggs and do dust bath in litter area. Therefore, these behaviors are considered for very important role in improving the welfare of laying hens. In EU and some countries, farmers must provide perches, nests and litter for the housing of laying hens. An understanding of behavior can lead to enhance physical health, emotional condition and welfare of laying hens. Unfortunately, there is little information on behavior of laying hens in Korea. Therefore, we researched the literature on certain behavior of laying hens.
