STATEMENT OF PROBLEM: The degree of conversion may influence the ultimate mechanical and physical properties of provisional crown and fixed partial denture materials. The high levels of the unreacted residual monomer may cause deleterious effect on the properties. PURPOSE: The purpose of this study was to measure the degree of conversion of bis-acrylic based provisional crown and fixed partial denture materials by using an infrared spectroscopic method. MATERIAL AND METHODS: Chemically activated three bis-acrylic based provisional crown and fixed partial denture materials, LuxaTemp [DMG, Hamburg, Germany], fast set TemPhase [Kerr, Orange, CA, USA] and Protemp 3 Garant [3M-ESPE, St Paul, MN, USA], were investigated by Fourier transform infrared spectrometry (FTIR). The FTIR spectra of the materials tested were immediately obtained after mixing. The specimens were stored under dry conditions and at $23^{\circ}C$ for 24 hours, and then the spectra of the materials were also obtained. The degree of conversion (%) was calculated from the spectrum of the absorbance between the aliphatic double bond at 1637 $cm^{-1}$ and the aromatic double bond at 1608 $cm^{-1}$ using the baseline method. The data were statistically analyzed using one-way ANOVA and the multiple comparison Scheffe test at the significance level of 0.05. RESULTS: The mean value and standard deviation of the degree of conversion were 52.5 % ${\pm}$ 1.1 %, 50.3 % ${\pm}$ 0.8 %, and 42.3 % ${\pm}$ 4.9 % for LuxaTemp, Protemp 3 Garant and fast set TemPhase, respectively. There was no significant difference between LuxaTemp and Protemp 3 Garant, whereas there was a statistically difference between Protemp 3 Garant and fast set TemPhase, and LuxaTemp and fast set TemPhase (P < .05). CONCLUSION: The degree of conversion of fast set TemPhase was significantly lower than those of the others. The degree of conversion may be correlated with the rate of polymerization.

This study was conducted for the evaluation of the effects of singing program combined with physical exercise on the physiologic changes, perception function and degree of depression. The subjects were the members of elderly women's glee club in D care center for the elderly, who have been singing for more than 6 months. 30 members were allocated to study group and 30 to control group. The singing program designed for both physical therapy and music therapy was consisted of initial physical exercise, singing art songs and classical song and the finishing physical exercise. This program was performed twice a week and about forth minutes was consumed for one session. We checked the heart rate, peripheral arterial oxygen saturation, perception function and degree of depression before and after the program. We used a pulse oxymeter to check the heart rate to oxygen saturation and a questionnaire for the evaluation of perception function and degree of depression. We need SPSS program for data analysis. The results of the investigated personnel complying with general characteristics were analyzed by frequency, two groups by t-test, data before and after the program by paired t-test, respectively. The results were as follows. 1) Heart rate after the program was significantly lower than that before program in test group(p<0.05). 2) Peripheral oxygen saturation after the program was significantly higher than that before the program(p<0.05). 3) Ability to match the right sign with a certain predetermined number was improved after the program. The frequency of wrong matching the sign with number before program was 30. But the frequency was decreased to 8 after the program. 4) Ability to calculate was improved after the program. The frequency of wrong calculation before the program was $1.10{\pm}1.94$. But the frequency after the program was decreased to $0.97{\pm}1.84$. 5) The degree of depression after the program($2.07{\pm}0.49$) was significantly lower than that before program(p<0.001). These results show that singing program combined with physical exercise improves the oxygen delivery to peripheral circulation, stability of heart function, the perception function(calculating and matching ability) and decreases the degree of depression. In conclusion, singing program combined with physical exercise can be used for the effective measure to improve the health of elderly and prevent dementia.

기존의 노화도 측정법은 분석시간이 오래 걸리고 노동력이 많이 드는 단점이 있어 이를 개선하기 위해 신속 간편하고 비파괴적인 근적외선 분광분석법(NIR)을 노화도측정에 적용하였다. 밥을 $4^{\circ}C$에서 저장하면서 6시간 간격으로 시료를 채취한 후 동결 건조하여 분말화 한 것을 시료로 하여, 각기 다른 노화($0.0%{\sim}47.1%$)를 나타내는 시료들의 노화도를 NIR을 이용하여 추정하였다. 표준분석법으로는 기존의 분석방법인 glucoamylase를 이용한 효소적 방법에 의해 호화도를 측정하여 이로부터 노화도를 산출하였다. 일정 수분함량인 각 시료의 2차 미분 스펙트럼으로 부터 노화에 의한 흡수(吸收)띠의 변이는 1360, 1434, 1528, 1700, 1780, 1928. 2100, 2284, 2320 nm 영역에서 관찰되었다. 수분함량 5% 이하의 분말시료 32개를 사용하여 이의 2차 미분 스펙트럼으로 부터 노화도를 추정하기 위한 검량식을 구하였으며, 이때 상관계수는 0.9753, SEC는 3.64% 및 SEP는 3.91%를 나타내어 노화도측정을 위한 NIR의 적용 가능성을 보여주었다. 각기 다른 수분함량을 갖는 시료의 노화도 측정에 이 검량식을 적용할 경우 측정시료의 수분함량이 7.0%, 11.4%로 증가함에 따라 SEP와 bias가 증가하고 상관계수가 낮아져 NIR에 의한 노화도의 측정시에는 검량식의 작성에 사용된 5% 이하의 수분함량의 시료를 사용하여야 할 것으로 사료된다.

The measurement of angled erythrocyte sedimentation rate (ESR), as a replacement for perpendicular ESR, for cattle blood was scrutinized since it has been well known that perpendicular ESR in cattle is too slow to be adopted as an effective clinical test. Samples of blood were taken from 186 Korean native cattle over 2 years old. The results obtained in the experiment were summarized as follows. 1. Average values of perpendicular ESR/24hrs in 15 apparently healthy cattle, as measured by Wintrobe, Westergren and capillary tubes, were $5.8{\pm}2.2$, $11.1{\pm}3.7$ and $10.4{\pm}4.5%$ respectively, which were found to be similar to the values of perpendicular ESR/hr of normal blood of human. 2. The ESR was determined in the tubes held at 90, 75, 60, 45, 30 and 15-degree angles, using 3 types of tubes. For the diagnostic purposes, the best results were obtained from the tubes held at 45-degree angle. 3. The angled ESR values increased as the diameters of the tube-bores decreased. 4. The tube length did not affect the angled ESR(%). 5. The angled ESR values increased with the increased environmental temperature during the ESR measurement. 6. The storage temperature at $5^{\circ}C$, $20^{\circ}C$ and $35^{\circ}C$, of the blood for 24 hours did not affect the angled ESR. 7. Samples of blood were treated with 4 kinds of anticoagulants (heparin, $K_2$-EDTA, double oxalate and sodium citrate) and the ESR was determined at 45-degree angle, using capillary hematocrit tubes. The ESR values were higher in the blood samples treated with sodium citrate than in those treated with other anticoagulants. 8. By using the autologous plasma, the PCV was adjusted to be 5, 10, 20, 30, 40 and 50ml/100ml and the ESR was determined in the capillary hematocrit and Wintrobe tubes held at 45 degrees. In both of the methods the ESRs increased as the values of PCV decreased. The regressions of ESR to PCV in both 45-degree-angled capillary and Wintrobe tubes were curvilinear. For the capillary hematocrit tubes the second degree polynomial $Y=61.9779-2.3533x+0.0228x^2$ (r=0.9999) fits the data. And in the case of Wintrobe tubes the second degree polynomial $Y=27.9767-1.1314x-0.0117x^2$ (r=0.9998) fits the data. 9. The 45-degree angled ESR was determined in the blood of 71 healthy Korean native cows using capillary hematocrit tubes. The average PCV was $35.4{\pm}3.6ml/100ml$. The observed ESR/hr averaged $7.2{\pm}2.7%$, while the corrected ESR/hr to a PCV of 36ml/100ml averaged $6.6{\pm}1.3%$. From these results it was concluded that to obtain the best results the ESR/hr of Korean native cattle should be determined at 45-degree angle at room temperature($20^{\circ}C$) using capillary hematocrit tubes.
