  • The paper is addressed to the topic of physiological response-specificity in disgust induced by visual stimulation. The purpose of this study was to evaluate reproducibility of physiological reactivity pattern during disgust elicited by the International Affective Pictures System (IAPS) in 2 experiments. Twenty-nine subjects participated in the first experiment with 3 visual stimulation sessions with disgust-eliciting slides (3 slides in each 1 min long session). In the second experiment disgust-eliciting slides from the IAPS were presented to 42 subjects in 2 sessions (one slide for 1 min). Spectral power of frontal EEG, skin conductance (SCL, SCR and NS.SCR), heart rate(HR), heart period variability(HPV) and respiration rate were recorded. Visual stimulation evoked 1:.n deceleration, higher power of high frequency component of HPV, increased SCL and NS.SCR frequency, frontal slow alpha blocking and moderate increase in fast beta power in most of the sessions in both experiments. However in the second experiment the EEG pattern associated with disgust showed inconsistent shifts in fast alpha and slow beta bands, but was marked by higher power of theta activity. Our data in both experiments emphasizes presence of disgust-specific profiles of autonomic and at the less extent EEG responses in visual stimulation context. Discussed are potential behavioral mechanisms leading to observed physiological manifestations in disgust elicited by visual stimulation. The results support the consideration that disgust is an withdrawal type negative valence emotion associated with relatively low autonomic arousal (low HR, low amplitude SCRs with relatively high NS.SCR frequency) and moderate EEG activation signs. Obtained data showed more consistent reproducibility of disgust-specific autonomic rather than EEG response patterns during visual stimulation design.

  • The purpose of this study is to analyze the preference and value of consumers through the package design of cosmetics with the concept of cause branding, and to propose a package design that can satisfy consumers' needs. I have recruited an experimental group that emphasizes the importance of package design in purchasing cosmetics. And Survey and in-depth interviews were conducted by comparing cause brand's product with general brand's product. In the first experiment, the items were classified into cognitive, emotional, and behavioral responses and a total of 31 subjects were surveyed. In the second experiment, six interviewees were interviewed through a questionnaire prepared by extracting 4 items from Sheth 's consumption value standard. As a result of the experiment, consumers preferred a design that can quickly and accurately grasp the information of the product. Especially, it is not easy to know whether it is a cause brand's product. So It should be stated in the package how it will be socially beneficial.

  • People believe that they make a rational decision. But the results of behavioral economics research show that people make a emotional decision at many times. The perception of fairness is one of the example in emotional decision. Sometimes people give up their monetary profit and revenge counterpart when they feel unfair. So the perception of fairness is very important. Two experiment was conducted. In experiment 1, researcher studied the effect of the pre-investment cost in perception of fairness. The result showed people who had pre-investment cost thought more unfair but were more likely to continue prior decision. In experiment 2, researcher studied the effect of type of CEO and message frame in perception of fairness. The results showed that people thought the proposal was more unfair when CEO was son of founder and message was gain and loss framing message.

  • Purpose: A study was conducted to ensure the structural safety of a raised girder bridge with improved cross-sectional efficiency compared to the conventional PSC girder. For this purpose, the cross-sectional specifications such as girder length, height, and width were determined, the arrangement of the tendons was designed, and the practical performance of the raised girder under static and dynamic loads was verified. Method: The static performance experiment examined the serviceability limit state by measuring behavioral responses such as deflection and cracking to primary and secondary static loads. In addition, the dynamic load loading experiment measured the acceleration and displacement behavior response over time to calculate the natural frequency and damping ratio to examine the usability limit state. Result: As a result of the static performance test, the deflection value based on the maximum applied load showed stable behavior, and the crack width measured at the maximum applied load level was very small, satisfying the serviceability limit state. In addition, a natural frequency exceeding the natural frequency calculated during the design of the dynamic loading experiment was found, and a damping ratio that satisfies the current regulations was found to be secured.

  • So far, the behaviors of Web users have been predicted or analyzed mostly by their demographic characteristics or by considering in which context they gain access to that. But now there is a question about whether those characteristics are the only factors to trigger their use of Web. If the answer is not affirmative, what types of additional factors could cause such an action and how they characterize it should be discussed. User profile information has been considered one of the crucial elements to define user characteristics in user-centered UI design sector, and in order to apply it to UI design, it's needed to meditate on the above-mentioned questions. In this study, it's first attempted to have a good understanding of the users of different media and to review existing user classification methods. Next, user classification variables and relevant scales were prepared to sort out users according to their type of using Web, and case study was conducted to identify the behavioral characteristics of users and classify them according to their behavioral features. Finally, the user profile features of individual user groups were figured out based on data that were gathered by making an experiment, and data mapping was fulfilled between the behavioral characteristics and user profile characteristics to find out what types of behaviors were caused by the characteristics of user profile. As a result, it's found that user characteristics could have an impact on not only their general information and relevant contexts but their attitude of using different media and personality type. There were some problems with the experimental design, but more accurate information on the relationship of user behaviors to user profile characteristics will be obtained if those problems are eliminated. As user behaviors could be predicted only by user profile characteristics, user classification is expected to make a contribution to enhancing the efficiency of UI design.

  • This experiment was carried out to determine the effect of breed and sex on behavioral characteristics and economic traits of performance-tested pigs. Totally 32 tested pigs in 4 different breeds were assigned for behavioral observation. Behavior was recorded for 4 hours(each 2 hours, before and after none) of tested pigs in each tested pen. The average daily gain, age at 90 kg and feed efficiency on the basis of the performance data were collected from 8,477 performance-tested pigs in which pure breeds of Duroc, Yorkshire, Landrace and Berkshire at the Korea Swine Testing Station. The results obtained in this study are summarized as follows; The effect of breed was statistically significant for all traits studied. Average daily gain were the highest(P<0.05) in Duroc and ages at 90 kg were the highest(P<0.05) in Berkshire. In feed efficiency of male, Landrace and Yorkshire were the most efficient. The average daily gain and feed efficiency were superior to those of female, however, the age at 90 kg was not different. Overally, females were superior to males in various traits examined. Berkshire breed had more proportion of time spent in ventral tying and sitting whereas the proportion of time spent in walking, drinking and eating was less than that of other breeds. The male pigs showed more time spent in standing and social behavior.

  • Ameliorating mechanisms of red ginseng on learning deficits were investigated in the following 3 experiments; its effects on 1) place learning deficits in aged rats and in young rats with selective hippocampal lesions (behavioral study), 2) long-term potentiation in the hippocampal formation (neuro- physiological study), and 3) ChAT (choline acetyl transferase) activity in various brain regions of aged rats (pharmacological study). In the behavioral study, first, performance in the place learning tasks were compared among 3 groups of young and aged rats; control young intact rats (10-12 week old) treated with water, aged rats (28-32 month old) treated with water, and aged rats (28-32 month old) treated with red ginseng (100 mghglday) suspended in water. Second, performance in the place learning tasks was compared among 3 groups of young rats; control intact rats treated with water, rats with bilateral hippocampal lesions treated with water, and rats with bilateral hippocampal lesions treated with red ginseng (100 mg/kg/day). Each rat in these 2 behavioral experiments was tested with the 3 types of the place learning tasks in a circular open field using intracranial self-stimulation (ICSS) as reward. The ICSS reward was delivered if the rat (1) moved distance of 100-160 cm (DMT): (2) entered an experiment-determined reward place within the open field, and this place was randomly varied in sequential trials (RRPST); or (3) entered 2 specific places, and did a shuttle behavior between the 2 places (PLT). Performance of the aged rats in the ginseng group was not significantly different from that of control young rats in ICSS (current intensity, bar press rates), DMT and RRPST. However, treatment with red ginseng significantly ameliorated place-navigation learning deficits in aged rats in the PLT. Similarly, red ginseng ameliorated learning and memory deficits in young rats with hippocampal lesions in the same tasks. In the neurophysiological study using young rats, perfusion of hippocampal slices with non-sapon in fraction of red ginseng significantly enhanced magnitudes of the long-term potentiation (LfP) in the CA3 subfield. In the pharmacological study, treatment with red ginseng did not affect ChAT activity in aged rat brain including the hippocampal formation. These results strongly suggest that red ginseng ameliorates learning and memory deficits in aged rats through actions on the CA3 subfield of the hippocampal formation, which were independent of the presynaptic components of the cholinergic system

  • Purpose : Adolescent/Adult Sensory Profile is the questionnaire to evaluate sensory processing based on daily activities. Self-questionnaire commonly tends to be biased to the characteristics of subject, so its validity is low. This study aims to analyze correlation between questions of Adolescent/Adult Sensory Profile and tactile threshold measured from cognitive behavioral experiment. Methods : The tactile threshold was calculated by tactile detection task and tactile stimuli were provided with the consistent current stimulator. The tactile threshold was compared with results of tactile processing items in Adolescent/Adult Sensory Profile and statistical correlation analysis was performed. Results : Scores in Low Registration and Sensation Seeking had positive correlation with the tactile threshold and scores in Sensory Sensitivity and Sensation Avoiding had negative correlation with the tactile threshold. Among them, only Low Registration was statistically significant. Conclusion : The questions in Low Registration(Tactile Processing)are highly correlated with physiological characteristics. As a result, it was shown that sensory inflow is less, if the tactile threshold is high.

  • We can usually found the children who do overactive and aggressive behaviors. They disrupt classroom order and cause other children immense damage. Their teachers exert themselves to control or manage them in class. This may lead to a reduction of precious time for teaching-learning classroom activities. This study has counseled those children doing overactive and aggressive behaviors with solution-focused brief counseling. This study also explores the following problems. First, how does solution-focused brief counseling affect their overactive and aggressive behaviors? Second, what changes do they experience through solution-focused brief counseling? Third, is solution-focused brief counseling useful in elementary schools? To do this study task, four students have been chosen with the help of teachers in the fifth year at B Elementary School in Ansan. The four children scored high in Mi-hyun Han's 'The ratings of the child's behavior problems' and Se-Yong Jeong's 'Life of school and behavior test'. They are all eleven years old and had two interviews before the experiment and five interviews during the experiment. The analysis of the counseling has been interpreted according to the different analytical methods based on the tasks. Solution-focused brief counseling's effect on children doing overactive and aggressive behaviors has been studied by quantity-analysis method, their changes in behaviors by quality analysis method; phenomenal and psychological method and the usefulness of this counseling in school surroundings by the joint of above two methods. The analysis has provided the following results. First, solution-focused brief counseling has been effective in the reduction of behavioral problems for those children doing overactive and aggressive behaviors and the continuation of the counseling has had a positive effect but it has depended on the individual characteristics and the degree of severity in their behaviors. Second, solution-focused brief counseling has lent itself to encouraging children to have egostrength, confidence, and volition in their behavioral changes with a favorable attitude to the counseling. Third, The egostrength formed through counseling has led children to a progressive direction of their behaviors in their school life. The increasing frequency in counseling has caused a decreasing time-period expected for counseling, and a feasibility of counseling with less resistance. In conclusion, solution -focused brief counseling may be a useful means to help children have positive self-esteem and lead a proper school life, leading to be a helpful facilitation for school site facing a deficiency of counseling.

  • This study carried out an experiment to find out the reaction of hairtail, Trichinus lepturus to the colors of LED light as a basic study on the development of the trolling gear and a method to enable the day-night operation. We used hairtails caught around Seongsan-po, Jeju Island by set nets and hairtail angling. The seven hairtails of the average length 68.9 cm (SD 9.2 cm) and the average weight 135.9 g (SD 47.9 g) were adapted themselves in the experimental water tank, 15 m Self-Governing 1.7 m in height and 1.5 m in depth, and then they were studied. We conducted experiment at the Ocean and Fisheries Research Institute in Jeju Special Self-Governing Province, from November to December 2015, and the sea surface temperature was between 16.5 and $19.5^{\circ}C$. The four colors of LED light, blue, white, green and red, were set up to transmit downward from the marginal area of tank. The 1 meter depth light intensity of LED colors is as follows: $0.09w/m^2/s$ (blue), $0.18w/m^2/s$ (white), $0.04w/m^2/s$ (green) and $0.007w/m^2/s$(red) To know the optimum LED color light, we selected one with better reaction rate after comparison of two colors simultaneously and the selected color was again compared to the other color in a tournament style two times a day (day and night) and ten times totally. The reaction rates were shown as the frequencies of hairtail appearance for 5 minutes in the lighting zone after turning on the LED lights. The reaction rate of the blue was at 97% unlike the red 3% (p < 0.001). The blue was at 75% unlike the green at 25% (p < 0.001). The blue was at 67% unlike the white at 33% (p < 0.001). Therefore, the color of light source showing the highest reaction rate was the blue.
