The purpose of this study was to evaluate the diagnostic performance of the senior dental students for the proximal dental caries on intraoral radiographs and to compare it with the dental hospital residents, the reference group. It was also investigated the diagnostic performance according to the carious lesion depth. Thirty-five intraoral periapical and bitewing radiographs with 213 proximal surfaces included in this study were selected from the dental patients at Chonnam National University Hospital. The observers were 181 senior dental students from 5 dental schools and 40 dentists who were second year resident from 5 dental hospitals. They were asked to evaluate the presence or the absence of the proximal dental caries. The results were as follows: 1. The mean of the hitting rate for the overall observers was 184.51 surfaces and the diagnostic accuracy was 86.62%. 2. The diagnostic performance of the sound proximal tooth surfaces was very high, i.e., 91.5% true negative rate and 8.5% false positive rate. 3. The diagnostic performance of the dentist group was higher than the student group(P<0.05). 4. The proximal dental caries perceptibility increased as the lesion depth increased significantly(P<0.001) except no difference between the carious lesion depth Ⅲ and Ⅳ(P>0.001).

Measuring the thermophysical properties of solids in laser heating method, the material surface is coated by thin black paint layer(graphite) to minimize the effects of the laser beam reflection. But, the influence of the thin black paint layer on the surface temperature variations have been ignored. In this paper, a numerical analysis is carried out to clarify quantitatively the influence of the thin black paint layer when the material surface is heated locally. In the experiment, the material surface is heated by Ar laser beam and the surface temperature profiles are measured by an infrared thermometer.

In this work, cell search which is one of the important functions of W-CDMA system in Rayleigh fading channel is studied by cell search simulation of asynchronous IMT-2000 system(3GPP). For the optimization of this process, three stages are considered: 1) slot synchronization, 2) frame synchronization, and 3) scrambling code identification. It is found that key system parameters such as Primary Synchronization Channel (P-SCH). Secondary Synchronization Channel(S-SCH), and Common Pilot Channel (CPCH) loading factor are optimized. It is noted that the smaller optimal threshold value, the larger SNR of the received signal. Therefore, it is important that the optimal threshold value should be selected in the region of SNR

Probiotics, enzymes, organic acids, oligosaccharides, antioxidants, and other functional materials are actively being explored as alternatives to antibiotics. Probiotics include live beneficial microorganisms that colonize the intestinal tract and competitively inhibit attachment and growth of harmful microbes. Probiotics also increase feed efficiency by assisting in nutrient absorption and digestion. The current study was conducted in order to evaluate the effect of a new probiotic, CS-A, as a dietary supplement of a fermented product on growth performance, feed intake, and feed conversion efficiency in broiler chickens, and to evaluate its value as an alternative for antibiotics used as a feed additive. Antibacterial and anti-inflammatory effects of CS-A were investigated in vitro and the in vivo effects of a constant concentration of supplemented CS-A on growth rate and feed efficiency were evaluated. In addition, the safety of CS-A was assessed by examination of common symptoms and mortality. Determination of minimal inhibitory concentration revealed an excellent antibacterial effect of CS-A. Cytotoxicity was low and anti-inflammatory effects were achieved at the effective concentration of CS-A. Supplementation with 0.1% CS-A resulted in a feed efficiency score of 1.84 in broilers, compared to 2.00 in the control group. There were no adverse clinical findings, necropsy findings, hematology, and altered serum biochemistry parameters, and no mortality. Thus, it is concluded that CS-A is safe and effective as a feed additive.

404 nurses and nurse-aids rated their experiences of 45 symptoms(Moos' Menstrual Distress Questionnaire) of the menstrual, premenstrual and intermenstrual phase on a 4 point scale separately. The 45 symptoms were inter-related and factor analyzed separately for each phase. six common clusters of symptoms emerged from 3 phases, which were labeled concentration, motor tension, pain, pleasurable affect, autonomic reactions and water retention. Four clusters of symptoms emerged from premenstrual phase. These clusters were labeled instabillity, withdrwal reactions, depression and headache. The factor named unpleasurable affect emerged from intermenstrual and menstrual phase. Above findings were differed from the results of Moos' study in which eight basically replicated clusters of symptoms emerged from three phases. Through discussion of validity of this scale, and differences between results of Moos' and this study, we came to the conclusion that sampling of subjects, prospective longitudinal symptoms reporting, amount of variance in a symptom over the course of menstrual cycle and proper choice of factor analysis method would be salient variables to construct valid scale for measuring menstrual cycle symptoms.

Background : The aim of this report is to show that treadmill running exercise under well-controlled conditions is to improve of regeneration in rat gastrocnemius muscles after sciatic nerve crushing injury. Material & Method : Male Sprague-Dawley rats (1 month old) were submitted to bouts of exercise on a treadmill up a 10 degrees decline and speed is 24m/min for 60 min per day and gastrocnemius muscles were analysed at different exercise periods (5, 10, 15, and 20 days) by immunohistochemistry in comparison with injured non-exercised muscles. Rats were sacrificed at 9th (5 days exercise), 16th (10 days exercise), 23rd (15 days exercise), 30th day (20 days exercise) after sciatic nerve crushing injury. The regenerative processes were analysed by detection of routine immunoreactivity for the two intermediate filaments, desmin and vimentin. Desmin and vimentin are specific components of the cytoskeleton of striated muscle fibers and of mononuclear cells of mesenchymal origin including myoblasts, respectively. Results : Desmin was revealed in processes of degeneration and regeneration and vimentin was revealed in regeneration process. Non-exercised rats had more desmin- and vimentin-positive myofibers than that of treadmill exercised rats at 9th, 16th, 23rd, and 30th day after sciatic nerve crushing injury. At 30th day, non-exercised rats had several desminand vimentin-positive myofibers, but exercised rats had numerous normal myofibers. Conclusion : It is concluded that treadmill running exercise is able to improve regeneration processes in gastrocnemius muscles after sciatic nerve crushing injury.

According to the investigation made by analyzing cause of the detail about sports injury. We make this things an object of all the male representative players 254 out of 286 (88.81%) that took part in the whole event from April 15, 1988 to September 16, 1988 in Seoul Olympic Games. The results are as follows. 1. The representative players in Korea started in the athlete life at age 13.1 on the average. Gymnast early started at age 8.4 and yachtist was later at age 18 in the athlete life. 2. There are about 5.7 cases on the outbreak of the sports trauma per person of player a year. This came into existence near the ankle at the high rate of damage formed 11.90%. 3. A sort of sports injury in analysis muscular bruise broke out at the highest rate of occurrence formed 15.70%. 4. The greater part of representative players themselves the injury of trauma by massage (12.53%). Some of them undergo medical treatment to the specialist hospital once a year on the average. Most of hockey players have had experience in this kind of injury treatment three times one year to per person of players. A few of them showed 0.15 times per person a year. 5. Most of representative players have been periodically to the orthopedist formed 27.59 (732) out of all 2653 cases at the high rate of fact. Especially a sort of injury in analysis, the injury of ankle region showed the percentage 11.86 (704) out of all 5,937 cases at the highest rate. 6. The period of medical treatment of the representative players in Korea came out about 14.7 days. Besides period of the other player's treatment came out mostly from one to five days formed 44.82%(935 cases) 7. Manyof them have been roughly treated with muscular bruise in analysis of sports injury. They were taking pains with muscular bruise formed 15.65% (1003) out of all 6408 case. 8. In major cause of sports injury came into existence during the training with waste of physical stamina formed 35.89% and were beyond their power with practicing the game formed 48.09%. Also, a sort of those were brought about the cause of sports injury with desire of outcome too much during in the game formed 44.20%
