  • The aim of this study was to measure the suprathreshold taste intensity for sucrose, NaCl, citric acid, and quinine HCl in Korean young people using a whole-mouth, sip-and-spit procedure, employing the method of magnitude matching. The results were analysed in terms of sex, taste preference, and smoker or nonsmoker. One hundred twenty three subjects (61 male and 62 female, mean age of 25.2$\pm$2.1 years) were included for the study. Subjects were instructed to give nonmodulus magnitude estimates to the intensities of five concentrations each of sucrose, NaCl, citric acid, and quinine HCl; distilled water; 6 loudness levels of a 1,000-Hz tone, using the same 9-point intensity scale. Each of the 21 taste stimuli and 6 auditory stimuli are presented in random order twice. The auditory function is used to assess the absolute intensity function of the subject's taste system. The results were as follows; 1. The perceived taste intensity for sucrose, NaCl, citric acid, and quinine HCl increased progressively as the concentrations of taste solutions were increased. Most of the subjects are standing within the zone of mean value $\pm$1standard deviation in their total perceived intensity score, and nobody is outside the limit of mean value - 2standard deviation. 2. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl between males and females. 3. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl according to the difference in taste preference. 4. There were not significant difference in total perceived intensities for sucrose, NaCl, citric acid, and quinine HCl between smokers and non-smokers in males.

  • Recently in HCI research, emotion recognition is one of the core processes to implement emotional intelligence. There are many studies using bio signals in order to recognize human emotions, but it has been done merely for the basic emotions and very few exists for the other emotions. The purpose of present study is to confirm the difference of autonomic nervous system (ANS) response in three emotions (boredom, pain, and surprise). There were totally 217 of participants (male 96, female 121), we presented audio-visual stimulus to induce boredom and surprise, and pressure by using the sphygmomanometer for pain. During presented emotional stimuli, we measured electrodermal activity (EDA), skin temperature (SKT), electrocardiac activity (ECG) and photoplethysmography (PPG), besides; we required them to classify their present emotion and its intensity according to the emotion assessment scale. As the results of emotional stimulus evaluation, emotional stimulus which we used was shown to mean 92.5% of relevance and 5.43 of efficiency; this inferred that each emotional stimulus caused its own emotion quite effectively. When we analyzed the results of the ANS response which had been measured, we ascertained the significant difference between the baseline and emotional state on skin conductance response, SKT, heart rate, low frequency and blood volume pulse amplitude. In addition, the ANS response caused by each emotion had significant differences among the emotions. These results can probably be able to use to extend the emotion theory and develop the algorithm in recognition of three kinds of emotions (boredom, surprise, and pain) by response measurement indicators and be used to make applications for differentiating various human emotions in computer system.

  • Objectives: To explore the quality of life in patients with temporomandibular disorders and to evaluate it in terms of source and duration of the pain. Methods: A total of 61 patients with temporomandibular disorders participated in this study. According to pain source, they were divided into 2 groups, masticatory muscle pain (MMP) group and intracapsular pain (ICP) group. And each group was divided into acute phase group (pain duration <6 months) and chronic phase group (pain duration=6 months). The Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to measure patients' quality of life. The scores for eight-scale profile and the physical component summary (PCS) and mental component summary (MCS) of the SF-36 were compared between groups (MMP vs. ICP and acute vs. chronic). Student t-test was used to analyze the difference of the scores of the SF-36 between MMP and ICP groups. Results: MMP group showed significantly lower score in the 3 scales of the SF-36 (Role limitations due to emotional problems, Vitality, Bodily pain) when compared to ICP group. In acute phase there was no significant difference between MMP and ICP group in PCS as well as MCS scores, but in chronic phase MMP group showed significantly lower MCS score than ICP group. Conclusions: The masticatory muscle pain in patients with temporomandibular disorders,negatively influences the quality of life especially in chronic phase, and the mental components of quality of life are significantly interfered in the TMD patients with chronic masticatory muscle pain.

  • This study was performed to investigate non-invasive behavioral pain assessment of dogs after surgery, and the analgesic effects of butorphanol after intestinal anastomosis in dogs. In this study, five dogs in the Control Group were anesthetized, but did not undergo surgery. Five dogs in the Analgesic Group were undergone intestinal anastomosis and treated with butorphanol. Five dogs in the Non-analgesic Group were also undergone intestinal anastomosis without analgesic treatment. The dogs in the Analgesic Group received butorphanol (0.4 mg/kg, IM) before and immediately after operation, while dogs in Control and Non-analgesic Groups received isovolumetric doses of sterile saline. The behavior of dogs were videotaped for 400 mins after anesthesia, during which time a researcher interacted with the dog once per each 80 mins. At each interaction, the researcher recorded behavioral pain score, using University of Melbourne Pain Scale. Interactive and non-interactive behaviors were observed and quantitated by a single observer using focal continuous sampling method. Vocalizations were obtained during 400 mins after anesthesia, and duration of call, intensity, pitch, 1-4 Formant were analyzed. Surgery affected an increasing of pain score. During interactions with researcher, greeting behaviors were decreased after surgery. Differences between Analgesic group given analgesic or that given a placebo drug were readily understood using quantitative behavioral measurements and vocalization. Significant difference between Analgesic group given butorphanol or that the given placebo drug was apparent(p< 0.05).

  • The advantages and disadvantages of the various models of crushed ESWL (Extracorporeal Shock Wave Lithotripsy) and their various side effects due to pre-treatment have been reported. We look for the appropriate intensity of the shock wave in the electromagnetic ESWL treatment of patients with lower Inferior Ureter Stones and measure the total running time of C-arm saw. This study is based on the January-June 2014 launch of 65 patients of C university hospital located in Gyeongbuk, who conducted ESWL without pre-treatment. Patients are composed of 48 male and 17 female which were more common in men, while the most common age is 50s. The occurrence of lower urinary tract stones were left and they were more absent than 5mm in size in 39 of the most common. Optimal intensity is one of the suitable intensity of pain, and it is possible to switch the strength of impact to C if one appeals pain. In addition, the C-arm of the total operating time showed $241.73{\pm}30.37$ seconds, which is the size of the lower urinary tract that showed a significant difference (p <0.05). Therefore, ESWL treatment without pre-enforce treatment, the standard for the impact frequency and impact strength depending on the site of ureteral stones is required. The standard for total operating time of C-arm generated for ureteral stones is needed in order to reduce radiation exposure, and the standard for the total operating time for the criteria is needed depending on the site in order to minimize the exposure.

  • The aims of this study was to observed an effect of antioxidative in cardiac muscle of high fat diet induced obesity rat by treadmill exercise with intensity and time. Thirty-two Sprauge-Dawley rats which were divided into four group. Normal, Control(high fat diet induced obesity rat), Experimental I(high intensity intermittent exercise in high fat diet induced obesity rat), Experimental II(moderate intensity endurance exercise in high fat diet induced obesity rat). The results of this study were as follows: 1. In change of body weight, the outcome of each group significantly difference compared with control. Also, 1 to 3 weeks significantly different compared with pre valu experimental I and II(p<0.001). 2. In change of lipid profile, the outcome of each group significantly difference compared with control(p<0.001). Difference between experimental I and II is not significantly. 3. In change of antioxidative enzymes(SOD, CAT, GPx) in myocardium, there are significant difference between control and experimental II, and also between control and experimental I(p<0.001). 4. In change of antioxidative protein MCR-1, the outcome of each group significantly difference compared with control(p<0.01). Experimental II was most significantly difference than the other group(p<0.001). The above results suggest that treadmill exercise effectively reduced in fat. It would be considered that moderate intensity endurance exercise has an effects on improved antioxidative enzyme in cardiac muscle of high fat diet induced obesity rat.

  • 척수에서의 통각전달은 말초에서 전달되는 통각정보가 척수내의 척수세포에 전달되면서 시작된다. 척수에 전달된 유해자극 정보는 척수내의 이차감각세포를 통하여 시상으로 전달되고 이로 인해 통증을 느끼게 된다. 이러한 척수내의 세포는 연수등의 여러 부위에 존재하는 신경 세포에 의하여 억제를 받으며 이와 같은 하향성 억제는 뇌에 존재하는 내재진 통계를 설명하는 중요한 인자가 되고 있다. 본 실험은 하부연수에 위치하는 신경핵인 Lateral reticular nucleus가 이러한 하향성 억제를 가졌는가를 알아 보고자 하였다. 이를 위하여 고양이를 마취시키고 척수궁을 절제하여 척수를 노출시키고 미세전극을 꽂아 척수세포의 활성을 기록하였다. 여덟마리의 고양이에서 31개의 척수세포를 기록하였다. 이 세포들 중 WDR세포가 14 (45%), HT가 9 (29%), LT 및 Deep세포가 각각 4 (13%)가 되었다. 이 척수세포에 북외측하부 연수인 lateral reticualr nucleus 주위를 건기자극하면 21개 (68%)의 세포가활성의 억제를 받았고 9개의 (29%) 세포는 아무런 변화가 없었고 1개의 (3%) 세포는 흥분되었다. 전기의 자극은 강도 100$\mu$A이며 자극길이는 100$\mu$S 그리고 100Hz의 주파수를 가진 펄스파였다. 이와같은 북외측하부연수의 전기자국은 신경세포의 자발활성뿐 아니라 수용장 자극에 의한 반응도 억제하였다.
