  • Though relatively little is known of the physiology involved, there is reduced kidney activity during hibernation. In this experimental study, male Korean chipmunks (Tamias sibiricus barberi) were maintained in cold conditions ($6^{\circ}C$) for 9 months, in an attempt to mimic conditions occurring during seasonal hibernation. The examination was made to determine changes of glycoconjugates on the kidney after hibernation by lectin histochemistry. The changes of lectin affinities in the kidney categorize into three groups: a) increase ones only in the early hibernation stage b) increase ones during hibernation and c) decrease ones during hibernation. The transient increase of Con A affinity in the proximal convoluted tubules were demonstrated only in the early cold-treated stage, and PNA and Con A in the distal convoluted tubules and DBA and sWGA in the collecting tubules. SBA affinity tended to increase with hibernation in the proximal convoluted tubules, but sWGA affinities were significantly decreased in the all tubule examined with hibernation. The present results suggest that the glycosylation pattern of the kidney undergoes profound changes during hibernation, and is probably associated with transiently reduced renal function.

  • The purpose of this study is to develop basic data in improving quality of life along with the enhancement in oral health, by arranging a plan for being able to reduce dental fear given the dental treatment in the future by grasping the subjective oral health recognition & status, and the dental fear level of the dental treatment field targeting patients of visiting dental clinics in Busan and Gyeongnam area. In the whole items of DFS, a sense of fear was higher in women than men. A factor of avoiding dental treatment stood at 1.72 points in men and 2.10 points(p<0.001) in women. A factor of response to stimulation stood at 2.75 points in men and 3.20 points(p=0.001) in women. A fear level according to dental kind was high in a factor of avoiding implant treatment(p=0.015), a factor of avoiding orthodontic treatment(p=0.002), physiological reaction(p=0.009), a factor of avoiding prosthesis treatment(p=0.014), a factor of avoiding pulpectomy treatment(p=0.005), a factor of physiological reaction(p=0.017), a factor of avoiding periodontal therapy(p=0.013), a factor of physiological reaction(p=0.004), and a factor of avoiding treatment given not receiving regular checkup(p=0.027). In the above results, to reduce dental fear, there will be a need of developing diverse programs and oral health eduction for regular checkup and preventive treatment.

  • This study used intersubject representational similarity analysis (IS-RSA) to identify participant-response consistency patterns in previously published data. Additionally, analysis of variance (ANOVA) was utilized to detect any variations in the conditions of each experiment. In each experiment, a combination of ASMR stimulation, visual and auditory stimuli, and time-series emotional video stimulation was employed, and emotional ratings and physiological measurements were collected in accordance with the respective experimental conditions. Every pair of participants' measurements for each stimulus in each experiment was correlated using Pearson correlation coefficient as part of the IS-RSA. The results of study revealed a consistent response pattern among participants exposed to ASMR, visual, and auditory stimuli, in contrast to those exposed to time-series emotional video stimulation. Notably, the ASMR experiment demonstrated a high level of response consistency among participants in positive conditions. Furthermore, both auditory and visual experiments exhibited remarkable consistency in participants' responses, especially when subjected to high arousal levels and visual stimulation. The findings of this study confirm that IS-RSA serves as a valuable tool for summarizing and presenting multidimensional data information. Within the scope of this study, IS-RSA emerged as a reliable method for analyzing multidimensional data, effectively capturing and presenting comprehensive information pertaining to the participants.
