  • 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.

  • 본 연구는 현재 전국의 모든 영재교육 기관에서 영재 학생을 선발할 때 적용하고 있는 관찰 추천 방법에 활용 가능한 영재 행동 특성 체크리스트를 개발하는 것을 목적으로 하고 있다. 기존 영재 행동 특성 체크리스트들은 제시한 문항들이 학교생활을 통해 관찰이 불가능하거나 애매한 항목들을 다수 포함하고 있거나, 영재 행동 특성으로서 그 중요도가 떨어지거나, 유사한 특성들이 반복되거나 혹은 다수의 문항으로 인해 실제 관찰 추천에서 활용도가 떨어지는 등의 문제점들이 지속적으로 제기되어 왔다. 이에 본 척도는 기존 연구에서 제시하고 있는 영재 행동 특성 요인들을 바탕으로 학교 현장에서 학생들을 직접 지도하고 있는 영재 교사들에 의해 '실제로' 관찰 가능성이 높은 영재 행동 특성과 각 특성들의 '중요도'를 반영했다는 데 의의가 있다. 본 척도는 현장의 영재 지도교사들을 대상으로 영재 행동 특성 요인과 구체적인 행동 양상에 대한 개방형 설문을 받고, 이를 전문가 그룹의 검토와 예비 검사, 본 검사, 확인적 요인 분석의 과정을 통해 개발하였다. 관찰 가능성과 중요도란 기준 적용으로 개발된 체크리스트는 일부 요인들을 제거하여 최종적으로 10개의 하위요인(논리적 사고, 높은 성취도, 독창성, 완벽주의, 창의적문제해결력, 호기심, 과제집착력, 의사소통 능력, 창의성, 활동성(열정))으로 구성되었으며, 각 요인별로 2~4개 문항이 제시되어 총 32개의 행동 특성 문항으로 개발되었다. 최종 32문항에 대한 내적합치도(${\alpha}$)와 문항-총점 상관을 분석한 결과 모두 양호한 값을 보여 영재 행동 특성 척도의 각 문항이 해당 구인을 일관성 있게 측정하는 것으로 분석되었다. 또한 영재 행동 특성 체크리스트에 대한 확인적 요인 분석 결과 모든 문항들이 각 하위 요인에 높게 부하되어 영재 행동 특성을 측정하는 체크리스트로 적합하며, 현장에서 초등학교 영재 학생들을 관찰 추천할 때 활용할 수 있음을 시사하고 있다.

  • 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.

  • 사용자 중심 디자인이란 사용자들이 의식/무의식적 행동들에 간섭 없이 자연스럽게 융화할 수 있는 제품을 디자인 하는 것이다. 이에 따라 디자이너들은 사용자로부터 그들의 요구사항이 무엇인지 파악이 필요로 하여 사용자의 실제 환경으로 들어가 어떠한 행동을 하는지 제품과 어떤 인터랙션을 하는지에 대한 조사가 필요하다. 하지만 기존의 관찰기법은 관찰대상의 범위가 방대하여 관찰 및 분석 방법에 대한 조사 체계가 모호하게 제시된 경우가 많다. 따라서 본 연구에서는 실제 운전자 환경을 관찰 범위로 한정짓고 이론적 배경을 기반으로 운전자 행동 레벨 및 정황(Context) 요소를 정의하였으며, 사용자 활동 데이터를 추출하기 위한 관찰 방법 및 분석을 위한 체계를 제시하였다.

  • 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.
