The poultry industry, which produces excellent sources of protein, suffers enormous economic damage from diseases. To solve this problem, research is being conducted on the early detection of infection according to the behavioral characteristics of poultry. The purpose of this study was to evaluate the potential of a non-movement behavior observation method to detect sick chickens. Forty 1-day-old Ross 308 males were used in the experiments, and an isolator equipped with an Internet Protocol (IP) camera was fabricated for observation. The chickens were inoculated with Salmonella enterica serovar Gallinarum A18-GCVP-014, the causative agent of fowl typhoid (FT), at 14 days of age, which is a vulnerable period for FT infection. The chickens were continuously observed with an IP camera for 2 weeks after inoculation, chickens that did not move for more than 30 minutes were detected and marked according to the algorithm. FT infection was confirmed based on clinical symptoms, analysis of cardiac, spleen and liver lesion scores, pathogen re-isolation, and serological analysis. As a result, clinical symptoms were first observed four days after inoculation, and dead chickens were observed on day six. Eleven days after inoculation, the number of clinical symptoms gradually decreased, indicating a state of recovery. For lesion scores, dead chickens scored 3.57 and live chickens scored 2.38. Pathogens were re-isolated in 37 out of 40 chickens, and hemagglutination test was positive in seven out of 26 chickens. The IP camera applied with the algorithm detected about 83% of the chickens that died in advance through non-movement behavior observation. Therefore, observation of non-movement behavior is one of the ways to detect infected chickens in advance, and it appears to have potential for the development of remote broiler management system.

This study investigates the mutual effects of the physical environment and the characteristics of user's need in the children's libraries of open plan type. The children's library as a flexible space should accept user's diverse needs. Especially, Children express more positive and diverse behaviors than adults in physical environment. As the design information obtained from observation of children's behaviors are put to architectural design, the more affluent environment in which children can do positive behaviors can be made. We used two research methods of the behavior observation and interview for the children's library, and could formulate various using actions through the behavior setting observation for using library. A relational description for reading environment in this study, based on the affordance and the behavior setting theories, provided us with rich accounts for the psychological and sociocultural resources in the children's library. Consequently, the following results can be summarized. First, children need territories for family use and for place and are using library effectively through taking the two territories. Second, the zoning according to age category should be done, as behavior patterns were observed differently according to age. Third, the space composition with openness should be designed, as children need social relation and learning through imitation and observation.

It is said that the chinese medicine, Ginseng root has some effects on the central nervous system . Ginseng saponin was prepared from Ginseng methanol extract and its effect on general behavioral activity was studied in rats. Each experimental group was composed of 8 rats. The behavioral activity of rats was observed in terms of 7 components i.e. sleeping, lying, grooming, rearing, walking, eating and drinking. In each group, total duration of behavior-observation was 2 hours, which were devided into four 30 min-intervals. The behavior-observation was done 10 times for each interval, so total number of observation was 40 times throughout 2 hours. Ginseng sapoain showed central nervous system stimulant action in reduced sleeping component and in increased activity components. From the results of this study, it is suggested that Ginseng saponin inhibits the extrapyramidal action of chlorpromazine.

This research focuses on the development of gifted child behavior checklist which feasibly has application on the nation-wide gifted children observation-recommendation method. Corresponding measure has significance as it reflects actual observations of teachers teaching gifted children first-hand and involves measure of importance regarding each characteristic. An open survey on gifted children behavior characteristics lists and specific behavior patterns has been acquired from teachers in gifted education, and the checklist was developed through expert group review, pre-test, and confirmatory factor analysis process. The former checklists have shown several difficulties on application of observation-recommendation on the field due to behaviors that can't be observed in school, less important behaviors, and collide and duplicate behaviors etc. With regard to such problems, problematic clauses were removed based on the observation probability and importance of the behaviors. Ultimately, total of 32 behavior characteristic checklist consisting of ten sub factors(logical thinking, high achievement, originality, perfectionism, creative problem solving, curiosity, task commitment, conversation ability, creativity, passion) and two to three questions on each factor had been drawn. Through internal consistency test and item-total score correlation, each item of the measure has been analyzed to be consistently evaluating corresponding variables. In addition, the result of confirmatory factor analysis showed every item to be weighed appropriately on its sub-factor, strongly suggesting its feasibility on observation-recommendation of elementary gifted children as an appropriate checklist.

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.

In order to clarify the contact mechanism between specimen surface and probe tip in the surface observation by the AFM (atomic force microscope) or the FFM (friction force microscope), several molecular dynamics simulations have been performed. In the simulation, a 3-dimensional simulation model is proposed where the specimen and the probe are assumed to consist of mono-crystal line copper and a carbon atom respectively and the effect of cantilever stiffness is also taken into considered. The surface observation process on a well-defined Cu{100} is simulated. The influences of cantilever stiffness on the reactive force images and the behavior of probe tip were evaluated. As a resuIt, several phenomena similar to those observed by the actual surface observation experiment, such as double-slip behavior and dispersion in the stick-slip wave period were observed.

This study was performed to identify the relationships between parents' nurturing behavior and preschoolers' creativity. The differences of parents' behavior and children's creativity by children's sex were also analyzed. The subjects were one hundred and four children(54 boys and 50 girls) and their mothers. Parents' nurturing behavior was assessed by a nurturing behavior questionnaire administered to the mothers, preschoolers' creativity was rated by the author through observation of the children's responses. The reliability of observation was calculated from 10 among the 104 children. The reliability coefficient was .96. The results were as follows: First, there were significant differences in parents' behavior according to the child's sex. Girls' parents showed more affective and achievement oriented attitude compared to the boys' parents. Second, there were also significant differences in .children's creativity according to sex. Girls' originality and flexibility were higher than boys, however, significant differences between girls and boys in fluency and imagination were not found. Third, parents' nurturing behavior and children's creativity were strongly related to each other. Children's imaginations were strongly related to the mothers' behavior. Children's originality and flexibility were also significantly related to their parents' behavior, but children's fluency did not show relations with their parents' behavior.

User-centered design aims to develop device naturally without the interference of user' s conscious and unconscious behavior. Accordingly, designers need to understand their user's requirements, observe user behavior and interaction in the real environment. However, existing observations suggested a vast range of analysis system and observation techniques which are often ambiguous to the designers. Therefore, this research is aimed to propose an observation system for collecting data from user's behavior. In order to do so, we define the components and behavior level within the context of driving.

This paper discusses the problem of designing an observation function as coarsest as possible in supervisory control of discrete event dynamic systems. Some algebraic properties of two sets consisting of observation functions for which the given desirable behavior is realizable are investigated:these sets with a partial ordering turn out not to possess largest elements. Two natural methods of obtaining an observation function, which is frequently coarser than the identity mapping, are also presented. An example illustrates the use of these methods.
