  • The purpose of this study was to investigate whether there were any changes in taste sensitivity with recurrent aphthous ulceration. Nintyseven subjects(25 males and 72 females) were included for the study and they were categorized into 2 groups(recurrent aphthous ulceration 27 persons, control 70 persons), recurrent aphthous ulceration group was investigated in the department of Oral Medicine, College of Dentistry, Pusan National University from April, 2005 to August, 2006 and control group was investigated in the clinic at Incheon city from June, 2006 to August, 2006. The electrical taste thresholds were measured using an electrogustometer of the 4 different sites(tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows ; 1. The electrical taste threshold showed significant lower in the RAU group. 2. The electrical taste threshold showed significant lower in female group, and showed significant lower except soft palate in male group of the RAU group. 3. The electrical taste threshold showed a tendency to increase in all site of the multiple RAU group, but there were no significant differences. 4. The electrical taste threshold showed a tendency to increase in tongue lateral of the acute RAU group, and showed a tendency to increase in tongue tip, circumvallate papilla, soft palate of the chronic RAU group. 5. After treatment, electrical taste threshold was significant increase than initial visit in the RAU group. 6. After treatment, NAS showed a tendency to decrease in the RAU group.

  • The aims of this study were to establish the effect of gender and age on number of fungiform papillae and electrogustometric thresholds of the tongue, and to determine the relation between number of fungiform papillae and electrogustometric threshold. Sixty-two healthy subjects of 20 to 39 years old were enrolled in this study. Examination areas were defined as center, anterior, left lateral, right lateral, and posterior on the dorsal surface of the tongue, which was stained with methylene blue dye and photographed with a scale bar on it. The number of fungiform papillae within $1\; cm^2$ square area of each examination site was counted twice. The counted values were averaged to produce means. Taste thresholds were measured three times on each examination area using an electrogustometer. Means of the threshold values were calculated. 1. The number of fungiform papillae was the largest at the anterior examination area, followed by right lateral, left lateral, posterior and central. Women had more fungiform papillae than men at anterior, right lateral, and center areas. Subjects in twenties showed more fungiform papillae than those in thirties at anterior, right lateral, and left lateral areas. 2. Anterior area of the tongue measured the lowest electrogustometric threshold, followed by left lateral, right lateral, posterior and center. The threshold was higher in men at anterior and right lateral areas. The subjects in thirties had higher threshold only at right lateral area than those in twenties. 3. Electrogustometric threshold was inversely correlated with the number of fungiform papillae at anterior and posterior areas. The results showed that the number of fungiform papillae and taste threshold varied according to tongue locus, and they were influenced by age and gender. The results also suggested that the number of fungiform papillae was related to electrogustometric threshold inversely.

  • This study examined how the application of silver spike point (SSP) and acupuncture-like transcutaneous electrical nerve stimulation (A-TENS) on acupoints affects blood flow and pain threshold, using laser Doppler blood fluxes and the Commander algometer. Our study included 32 healthy men and women who were randomly divided into the SSP group (n=18) and the A-TENS group (n=14). The pain threshold and blood flow were measured at the Neiguan (PC6) of the Jueyin Pericardium Meridian of the hand. SSP was performed with a 2.8cm electrode at a fixed frequency of 3 Hz for 15 minutes. The change in blood flow and pain threshold after the intervention significantly differed between the two groups (p<0.05). We found that the application of SSP and A-TENS on an acupoint altered their blood flow and pressure pain threshold, with SSP resulting in significantly greater change than A-TENS. Based on these results, the convergence of acupoint and electrical stimulation therapy can be usefully applied as a method for various patients. Continued development of convergence interventions is necessary.

  • Mambo, Usuda, Okamoto에 의하여 최초로 제안된 대리 서명은 원서명자가 지정한 서명자가 원서명자를 대신하여 서명하는 것을 허용한다. 본 논문에서는 이러한 대리 서명 중에서 보증서를 이용하여 부분 위임이 가능한 대리 서명과 역치 위임이 가능한 대리 서명을 제안하였다. 보증 부분 위임은 Mambo가 제안한 부분 위임과 Neuman의 보증 위임의 장점을 결합한 것으로 암호 요율성 또한 좋다. 역치 위임은 원서명자가 n명의 대리 서명자를 지정하고 n명의 대리 서명자중 t명 이상의 대리 서명자가 협조하여야 대리 서명을 할 수 있는 개념으로 본 논문에서 threshold위임에 의한 대리 서명 방식을 제시하였다.

  • The purpose of this study was to investigate the taste sensitivity in patients with oral mucosal diseases(Oral lichen planus(OLP), Recurrent apthous ulcer(RAU)) using electrogustometer. One hundred and seventy three subjects were included for the study and they were categorized into 2 groups(control 100, patient 73) and patient group was investigated in the Department of Oral Medicine, Pusan National University Hospital from April, 2005 until January, 2007. Control group was investigated in the clinics at Inchen Metroplitan city and Cheongju city from February to August, 2006. The electrical taste thresholds were measured by using an electrogustometer for the 4 different sites(tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows ; 1. The electrical taste threshold in patient group was significantly decreased than that in the control group(p<0.001). 2. The electrical taste threshold, in terms of the chronicity and lesion multiplicity, was not significantly changed in patient group. 3. The electrical taste threshold was not significantly changed in Dexan only and Dexan+Prs combination treated group. 4. The electrical taste threshold, in terms of treatment progress(no response vs half response vs complete response), was not significantly changed. However subjective index which was determined by NAS(Numerical Analogy Scale) was significantly increased in no response group but significantly decreased in complete response group(p<0.001)

  • The aim of this study is to determine a relationship between the smoking and the gustation. For that purpose, the survey is about the subjective taste change after smoking compared the electrical taste thresholds by EGM on healthy young Korean men before and after smoking. The results of the electrogustometry showed significant differences between smokers and non-smokers, also between before smoking and directly after smoking in smokers showed significant differences which indicated the immediate, but temporary effects of smoking on the taste thresholds. There were no difference of gustatory function by the amount of smoking and the degree of addiction. Based on the results of this study, further studies will be focused on the difference of gustatory function between before and after smoking using the chemical taste test, and the relationship between change of olfactory and gustation by smoking.
