  • The studying and teaching of behavioral neurology remain in their infancy. As the arena for studying how the brain subserves cognition, emotion and consciousness, behavioral neurology straddles the boundaries of numerous, more established disciplines-extending from the most fundamental explorations of molecular biology to the broadest questions of philosophy. In behavioral neurology, the area of neural dysfunction as well as the pathogenesis must be determined. There are cases in which a more thorough mental status examination must be performed. These are practically the cases with known or suspected brain lesions and acute psychiatric disorders.

  • This study is aimed to inspect how the different sensitivities in Behavioral activation system (BAS) and Behavioral inhibition system (BIS) modulate on the properties of physiological responses stimulated by positive or negative affective sound. We measured the electroencephalogram (EEG) of 32 students, consisted of four groups depending on the BAS and BIS sensitivities, during listening to meditation music or noise. The EEG was recorded at Fp1 and Fp2 sites. After listening to music or noise, subjects reported the affect induced by the sound. For EEG, the power in the alpha band at Fp2, especially in the alpha-2 band (9.0-11.0 Hz) increased during the subjects listening to music, while the power at Fp1 increased during noise. During listening to meditation music, there is a tendency that the left-sided activation in prefrontal cortex (PFC) is positively correlated with the difference of BAS(Z)-BIS(Z). During listening to noise, there is a tendency that the right-sided activation in PFC is dominant in case any of the sensitivity of BAS or BIS is high. From these results we suggest that the physiological responses of different individuals in BAS and BIS react differently under the same emotionally provocative challenge.

  • Near-Field Communication (NFC) is a short-range wireless communication technology evolved from RFID especially for the exchange of data between active and passive devices. This paper presents the mathematical models for the signal path of a NFC transceiver system and a behavioral simulation platform using MATLAB simulink. The approximated mathematical models simplify the simulation complexity of a transceiver and provide a quick evaluation. With this calculation platform, we can evaluate the system performance caused by the noise and the non-linearity of the individual blocks, and caused by system variables such as Effective Number of Bits (ENOB) of ADC and filter cutoff frequency. This platform provides us with a rapid prototyping, a reliable system design, and an efficient risk management during development of the NFC transceiver ICs.

  • This study was trying to find the differences of the levels of e-commerce system satisfaction and a relationship between system satisfactions and behavioral intention to use e-commerce system continuously. Based on the previous studies, we identified the factors of system satisfaction that were consist of system readiness, accuracy, content, ease of use, timeliness and IT Support. The system satisfaction levels of martial status and the training status of hospitals had significant differences. In martial status, un-married managers had higher levels of ease of use and timeliness than the married. In this result, we might consider an age effect for younger persons are more likely to use IT and have more satisfaction perceptions. Rather than training hospitals, non-training hospitals had higher level of ease of use and IT support, which could be interpreted as e-commerce systems of training hospitals might not match their own managerial purposes and need an improvement of their system functionalities. This study also identified that the factors of system satisfaction has a relationship with behavioral intentions. Except accuracy and IT support of all six system satisfaction factors, four factors were significantly correlated with system usage intentions in their e - commerce works.

  • The purpose of the present study was to investigate the differences of nonlinear characteristics of electroencephalogram (EEG) depending on different sensitivities of behavioral activation system (BAS) and behavioral inhibition system (BIS) of young and elderly groups. The EEGs from Fpl and Fp2 electrodes were recorded during resting condition. The young and elderly groups consisted of 19 and 31 healthy right-handed volunteers, respectively. We estimated 1/f scaling exponent which reflects the nonlinear dynamical complexity of EEG. As results, we found the differences of 1/f scaling exponent between young ant elderly BAS sensitive groups. The 1/f scaling exponent of young BAS sensitive group showed significantly higher values than those of elderly BAS sensitive group at the left prefrontal area (Fpl). The young BAS sensitive group had also a tendency to higher 1/f scaling exponent at the right prefrontal area (Fp2). Decrease of the 1/f scaling exponent indicates the increase of complexity and the decrease of the amount of information related to the statistical distribution. Therefore, the elderly BAS sensitive group has higher complexity than young BAS sensitive group, though they were all classified as BAS sensitive group by BAS/BIS scale. Our results suggest the possibility of correlation between BAS sensitivity an4 age.

  • The purpose of this study is to suggest a direction for eco-friendly healing space design for healthcare facilities in the future. Theoretical review and case study on the concept of sustainable design, spatial expression and behavioral affordance were used as research method. Through these reviews, the 3 elements of the total healing environment -physical, psychological and social- have correspondence with elements of spatial expression; Refuge, Flow, Prospect and Void. And these are related to the eight kinds of Behavioral affordance which are subdivided into WORK&STUDY, REST, CIRCULATION, VISUAL SEQUENCE, SOCIAL EXCHANGE, REFRESHMENT, COMMUNITY and MEDITATION. And the concept of sustainable design consists of 6 principles ; Natural system, People, Place, The cycle of life, Energy & natural resources and Process. Through correlation analysis of behavioral affordance and 6 principles, the result of this study presents that the physical elements of the total healing space was mainly associated with the principles of people, place and the cycle of life. Psychological element was related to principle of natural system, human, place and process. And social element was associated with the principles of human, place and process. According to this analysis, the case study of four low-rise eco-friendly medical facilities was undertaken. Sustainability was evaluated in total healing environmental through this case study.

  • The fish influx and behavioral properties at a set-net off Goseong, South Korea were investigated using an imaging sonar. As a result, the average influx of fish was 33.9% at day time and 66.1% at night time, respectively, which indicated that a majority of fish entered into a playground in the set-net at night. The fish behavioral properties such as target (fish) length, range, orientation and major-axis angle were examined and compared among survey dates (4, 5, and 6 June 2019) using the statistical analysis tool (analysis of variance, ANOVA). The behavioral properties presented differently sometime of survey dates. This is preparatory study to support fish behavior properties in a set-net. It is expected that more elaborated behavioral information of fishes in the set-net is beneficial for designing and deploying a set-net fishing gear as well as general fish behavior research in the future.

  • The purposes of this study were to explain consumer attitude, behavioral intention and behavior(expenses) in the purchase of Han-gwa and to explore the influencing factors on them. To achieve these purposes, the Heckman two-step model was utilized to utilize the recursive system of attitude, behavioral intention and behavior. The results of this study were as follows: 1) Seventy-six percent of consumers presented their favorable altitudes to purchase Han-gwa, while $47\%$ of consumers had behavioral intention for purchasing Han-gwa. In addition, purchasing expense of Han-gwa per year as a proxy variable of behavior was less than 100,000 won for most consumers. 2) First, consumer attitude was found to be significantly influenced by the type of family and food safety. Second, the behavioral intention for purchasing Han-gwa was found to be significantly influenced by consumer attitude, age, income, education and price. Finally, consumer behavior(expenses) of purchasing Han-gwa was found to be significantly influenced by the behavioral intention, income and purchasing place.

  • This study explored the relationship of behavioral inhibition to narrative representations. Narratives of 96 four-year-old children were recorded and analyzed by the scoring system of Robinson, Holmberg and Klute(in press). Six clusters were found : Constrained(47.9%), Anxious/Restricted(23.9%), Emotional Integrated/Empathic(12.5%), Empathic/Avoidant(6.3%), Dysregulated(5.2%) and Anxious/Avoidant(4.2%) clusters. Behavioral inhibition was determined by observations using "Play with Unfamiliar Peers(Rubin et al., 2002)". Behavioral inhibition differences corresponded to the children's narrative representation clusters; The Anxious/Restricted Cluster was related to more and the Emotional Integrated/Empathic Cluster to less inhibited behavior. In context-specific differences, more inhibited behavior was related to Anxious/Avoidant Clusters during show-and-tess and to Empathic/Avoidant Clusters during card-sorting activities, respectively.
