  • A study was planned to see if the mammillary bodies have any influence upon orienting response Thirty-nine male rats were divided into two groups. One group of animals received electrolytic lesion of the mammillary bodies through stereotaxically implanted electrodes (mammillary body group), and the other group received the same treatment short of electrolytic lesion(operated control group). All animals were tested for orienting response 3 weeks after surgery. Orienting response was regarded as elicited when an animal in alertness ceased ongoing activity upon 1,000 Hz tone presentation and/or turned head toward the source of stimulus. Weak (momentary and inconspicuous) and strong (marked and more persistent) responses were discriminated. Occurrence and duration of orienting response were measured, and the rate of habituation was estimated in 20 trials. Shift of attention from sound to light stimulus (10 trials) as well as orienting response of thirsty animals to sound stimulus while drinking (5 trials) and while at rest (5 trials) were also tested. 1. Simple orienting respons to sound stimulus tended to occur more often and its duration tended to be shorter in the mammillary body group than in the operated control group. 2. With repetition of trials, the occurrence of orienting response in each trial decreased progressively in both groups (habituation). However, the rate of habituation was significantly less prominent in the mammillary body group than in the operated control group. 3. Under attention·shift situation, orienting response tended to occur less often and its duration tended to be shorter in the mammillary body group than in the operated control group. 4. Orienting response to sound stimulus while drinking to quench thirst tended to occur more often and its duration tended to be shorter in the mammillary body group than in the operated control group. In quiet state, however, there existed no group difference with regard to the occurrence and duration of the orienting response. Although no obvious inference can be drawn from the above results, they may suggest the mammillary bodies being involved in the orienting response as a control mechanism inhibitory to the occurrence and facilitatory to the habituation of the response.

  • To see if the treatments of d-amphetamine and chlorpromazine have any influence upon the orienting response and general behavioral activity, 3 groups of male Holtzman rats were prepared, namely d-amphetamine animals (1.0 mg/kg.i.p.), chlorpromazine rats (1.0 mg/kg.i.p.) and the physiological saline control animals. The general behavioral activity was examined by visual scanning using the time-sample method in the adaptation period of orienting response. The occurence of orienting response and its rate of habituation were evaluated by observing cessation of ongoing activity in response to a sound stimulus (1,000 Hz, 70 db & 0.1 sec), or turning of head toward the source of stimulus in 20 trials. Attention shift from sound to light stimulus was also tested in 10 trials. The results obtained were as follows; 1. The general behavioral activity of d-amphetamine group was significantly greater than that of control, however, the chlorpromazine animals showed the tendency to decrease in activity. 2. The d-amphetamine group showed the occurence of orienting response to sound significantly more often than that of placebo controls. However, the chlorpromazine group exhibited significantly fewer orienting response than the placebo group did. 3. The d-amphetamine group displayed no clear out habituation to the orienting response following the repetition of trials, though the placebo and the chlorpromazine groups demonstrated apparent habituation to the response. 4. The three animal groups did not differ significantly from each other with regard to shift of attention from sound to light stimulus. It is inferred that the d-amphetamine tends to increase general activity has a definite facilitative action of orienting response and a inhibitory influence upon the habituation of the latter response. On the contrary, the chlorpromazine tends to decrease general activity, has a inhibitory action of orienting response and facilitatory action of habituation of the response.

  • This paper covers topics related to the investigations for the problem of sensorless vibratory orienting of polygonal parts with high probability through dynamic simulation. The author's program for mechanical systems with changing topologies was experimentally validated and was used as a simulation and design tool for motion behaviors of the vibratory parts-orienting system in the dynamic environment. A flat level vibrating bar is proposed as a means of orienting parts. Dynamic manipulation, in which a part is repeatedly caught and tossed by the bar without sensing, forms the fundamental manipulation strategy. This paper presents how to plan vibratory manipulation strategies that can orient a small rigid polygonal part using interaction between the part and the vibrating bar without requiring sensing. The planned motion strategies have been experimentally validated to show how the dynamic simulation can be used to find favorable vibration parameters for a given part without knowledge of their initial orientations.

  • This study is on the internal and external characteristics along with the phenomena of dress and ornaments expressed in them by analyzing Re-orienting Fashion (which is a system of signs and symbols) based on the theories of semiology in the search for the Korean identity by examining a Re-orienting Fashion that is being reinterpreted. Re-orienting Fashion performs the role of signs that act in the spread of Oriental culture through the globalization of traditional dress and ornaments in the Orient. It also has a meaning that converts the world of fashion to a new direction. When analyzing the system of signs and symbols in Re-orienting Fashion (based on the theories of semiology) the conclusions are that an eclectic symbol system has been formed by the combination of the pursuit of modernization in traditional dress and ornaments with post-modernism. A nature-friendly symbol system has been shaped as a natural silhouette in terms of the combination with Eastern philosophy that searches for a harmony with nature according to ecological trends. The ideal of a symbol system means the introduction of design elements in traditional dress and ornaments of the East as a rejection of Western civilization and as an alternative to the fixed pattern of the West.

  • The purpose of this paper is to in vestigate a relative effectiveness of instruction among such three orienting methods as lecture, slide-tape and video-tape which the library of Duk Sung Women's University has applied for orienting the freshmen for the last three years. This research also carried out a sample survey by distributing uniform questinnaire to the three different groups of the students. Each group was oriented with lecture, slide-tape and Video-tape respectively. Finally, the empirical findings of this research are as follows: 1. All three orienting methods were useful for students to improve knowledge as to how to use the library, 2. There were a wide difference in effectiveness among three instructional methods, obviously, the slide-tape method was more effective in the orientation than the lecture method and, furthermore, the video-tape was more effective than the slide-tape one, Therefore, it seem safe to conclude that the media utilization effective in orientation program should be encouraged by the university libraries of Korea.

  • In the experiment carried out on 20 college students, recorded were frontal, temporal and occipital EEG, skin conductance response, skin conductance level, heart rate and respiration rate during listening to two music fragments with different affective valences and white noise administered immediately after negative visual stimulation. Analysis of physiological patterns observed during the experiment suggests that affective auditory stimulation with music is able to selectively modulate autonomic and cortical activity evoked by preceding aversive visual stimulation and to restore initial baseline levels. On other hand, physiological responses to white noise, which does not possess emotion-eliciting capabilities, evokes response typical for orienting reaction after the onset of a stimulus and is rapidly followed by habituation. Observed responses to white noise were similar to those specific to attention only and had no evidence for any emotion-related processes. Interpretation of the obtained data is considered in terms of the role of emotional and orienting significance of stimuli, dependence of effects on the background physiological activation level and time courses of attention and emotion processes. Physiological parameters are summarized with regard to their potential utility in differentiation of psychological processes induced by auditory stimuli.

  • In current study on 8 college students there was examined modulation of eyeblink (as measured by integrated EMG of m.orbicularis oculi) and skin conductance response (SCR) to an acoustic startle probe (85 dB[A] white noise) by attending to task presented in auditory modality (to memorize words for further recognition) and entire performance of the word recognition test. Both eyeblink magnitude and SCR amplitude and rise time to startle probes were modified (larger magnitude of EMG peak, lower amplitude and shorter rise time of SCR) during attending to task as compared to performance on test. Results are interpreted n terms of modification of electrodermal and eyeblink components of startle and orienting reflexes by task characteristics (passive versus active efforts), attentional demands and aversiveness of experimental situation. However, eyeblink startle response manifested potentiation during attending to task, while SCR demonstrated attenuation. There are discussed implications of startle modulatioas a potentially sensitive probe of situational demands in stress research and also are considered prospects for further studies.

  • The purpose of this study is to investigate relations between the organizational culture and job satisfaction of ordinary dental technicians who are serving at dental laboratories. Findings of the study are summarized as follows. Ordinary dental technicians' job satisfaction as a whole was measured 3.40 in average score. In detail, those dental technicians were highest in satisfaction about their work, followed by their work conditions, organizational relations and occupation itself in order, but showed some dissatisfaction in terms of their self-realization. Regarding relations between the organizational culture and job satisfaction of ordinary dental technicians, the former was found significantly affecting the latter. Those dental technicians' job satisfaction was being most positively influenced by innovation-orientation as one of their organizational culture styles, followed by task-orientation. In regard to relations between sub-areas of the satisfaction and styles of the culture, ordinary dental technicians' organizational relations were being significantly, positively affected by such styles of their organizational culture as relation-orientation and task-orientation. Those technicians' occupational satisfaction, self-realization and work conditions were being strongly influenced by one of their organizational culture styles, that is, innovation-orientation. Originary dental technicians' work satisfaction was not being significantly affected by any of the organizational culture styles. The more relation- or task-orienting ordinary dental technicians were in organizational culture, the stronger their organizational relations were. The more innovation-orienting ordinary dental technicians were in organizational culture, the more those dental technicians' satisfaction regarding their occupation, self-realization and work conditions is likely to positively change. These findings indicate that ordinary dental technicians are even more orienting both relation and task in organizational culture, while being afraid of innovation and that their organizational culture as a whole is somewhat strict hierarchically.

  • The purpose of this second one of the two consecutive papers, which carried out for the research, is to evaluate their relative effectiveness regarding instruction with such three presentation methods as video/print+ lecture, print/video, print+lecture/video, with which the library of Duk Sung Women's University applied already for the orientation of the freshmen in 1988. In sum, the major research findings are as follows : First, as the more numerous media were applied for the orientation, the instruction were more effective. Second, it is very interesting to find out that there were wide differences in effectiveness among the three presentation methods applied for the student. Especially, the print+ lecture/video method was more effective in the instruction than the print/video method. Surprisingly, the video/print + lecture method was much more effective than the print+ lecture/video method. With the research findings of this two consecutive papers into consideration, it seems safe to say that the video-tape method was most effective among such three orienting methods as lecture, slide-tape, and video tape, and the video/print+lecture method was most effective among such three presentation methods as video/print+lecture, print/video, and print+lecture/video.
