The author studied on the transfer of radioactive fluorine ($^{18}F$) to dental hard tissue through animal experiments which was divided into two groups. First group of rats were sacrified 1, 2, 5, 10 and 20 minutes after intraperitoneal injection. Second group were sacrified 1 and 3 minutes after topical application on anterior teeth. The teeth were removed and sectioned by means of abrasive wheel and polished on india stone as thick as about 50 microns. Autoradiograph picture was made by close contact of high-speed dental X-ray film on prepared specimen for 2 hours. The results of this study were as follows; 1) There was no evidence of transfer of $^{18}F$ on dental hard tissue on the cases of 1, 2 and 5 minutes survival after intraperitoneal injection. 2) Radioactive sodium fluorine incorporated to dental hard tissue was slight and diffuse at 10 minutes cases and significant incorporated picture was noticed at 20 minutes cases in intraperitoneal injection. 3) On topical application groups incorporated $^{18}F$ to enamel was traced clearly only on enamel surface at 1 minute cases and significant transfer into whole enamel was found at 3 minutes cases.

This study investigated the effect of changing position from supine to standing upright on the circulation of young men and women. Healthy men and women ranging from age of 18 to 24 were examined. Two minutes before standing, the baseline heart rate and blood pressure were measured. Heart rate and blood pressure were recorded immediately and at every minute for 10 minutes after standing upright. Differences in heart rate and blood pressure between supine and standing upright position were evaluated. The results were summarized as follows : 1. Heart rate increased significantly immediately and at every minute for 10 minutes after standing upright. 2. Systolic blood pressure increased significantly immediately and at every minute for 4 minutes after standing upright. 3. Diastolic and mean blood pressure increased significantly immediately and at every minute for 10 minutes after standing upright. 4. Pulse pressure immediately and at every minute for 10 minutes after standing upright was significantly narrower than that of supine position. 5. There was no significant difference of heart rate between men and women after standing upright. 6. Systolic and diastolic blood pressure of men after standing upright was significantly greater than those of women. From these results, it may be concluded that heart rate, systolic, diastolic and mean blood pressure and pulse pressure increase after standing upright, and systolic and diastolic blood pressure in men is greater than those of women after standing upright.

Italian poplar (Populus euramericana) rotary veneers were press-dried and air-dried to study drying curves, thickness shrinkage and width shrinkage of them under several drying conditions such as drying temperatures and veneer thicknesses. The results of the study are summarized as follows; 1. In press-drying, drying times from green condition to about final moisture content of 10 percent with veneer thickness of 0.6mm by platen temperatures required about 10 minutes at platen temperature of $100^{\circ}C$, 3 minutes at $110^{\circ}C$, 1 minute at $120^{\circ}C$ and $130^{\circ}C$, respectively. 2. In press, drying, drying times from green condition to about final moisture content of 10 percent by veneer thicknesses required 2 minutes at veneer thickness of 0.6mm, 4 minutes at 1.2mm,6 minutes at 1.8mm and 9 minutes at 3.6mm, respectively. 3. In air-drying, drying times from green condition to air-dried moisture content by veneer thicknesses required 15 hours at veneer thickness of 0.6mm, 18 hours at 1.2mm and 23 hours at 2.4mm, respectively. 4. Thickness shrinkage of press-drying was remarkably greater than that of air-drying, but width shrinkage of press-drying was rather smaller. 5. Difference of thickness shrinkage among platen temperatures was insignificant, and width shrinkage at platen temperature of $130^{\circ}C$ was the least.

The radioactive $^{131}I$-rose bengal serial scintiphotography was performed in 62 patients with the hepatobiliary diseases and in 20 normal subjects. This approach permitted visualization of the hepatic uptake of $^{131}I$-rose bengal from the circulation and its excretion into the biliary trees and the intestines. In some of these patients, gallbladder function was examined, using eggs as a gallbladder constrictor. The time of maximum hepatic uptake was well correlated to the conventional biochemical liver function tests. In addition to $^{131}I$-rose bengal scintiphotography, $^{198}Au$-colloid scintiphotography was also performed to make comparison of these two tests. The results obtained were as follows: 1. In normal subjects, the maximum hepatic uptake of $^{131}I$-rose bengal occurred at $23{\pm}2.9$ minutes, the initial hepatic excretion at $34{\pm}5.1$ minutes, the visualization of the gallbladder at $29{\pm}5.7$ minutes and the intestinal visualization at $54{\pm}25.8$ minutes. The radioactivity in the gallbladder decreased to $10.7{\pm}5.0%$ one hour after the ingestion of eggs. 2. In the patients with cirrhosis of the liver, there was a delayed and decreased hepatic uptake. The maximun hepatic upake occurred at $43{\pm}12.9$ minutes. The differences in the results of uptake between the cirrhotic and the normal group were statistically significant. The initial hepatic excretion occurred at $60{\pm}18.5$ minutes and had tendency of delaying compared with the normal controls. The gallbladder was visualized in 13 of 16 cases (81%) and its visualization occurred at $49{\pm}14.6$ minutes with a tendency to be delayed compared with the normal controls. The intestinal visualization occurred at $63{\pm}15.8$ minutes and its delaying tendency was somewhat more prominent. 3. In patients with hepatitis, the maximum hepatic uptake occurred at $59{\pm}21.4$ minutes and was significantly delayed. The initial hepatic excretion occurred at $82{\pm}34.3$ minutes and the results revealed a delaying tendency. The gallbladder was visualized in 15 of 20 cases (75%) at $57{\pm}18.7$ minutes, which was significantly delayed. The Intestinal visualization was noted in all cases with marked delay. 4. In patients with obstructive jaundice, the maximum hepatic uptake was noted at $83{\pm}14.7$ minutes, showing the most significant delay. The hepatic excretion into biliary trees and intestines was not entirely noted in all cases except the only one case with gallbladder visualization. 5. In patients with cholelithiasis, the maximum hepatic upake and the initial hepatic excretion were slightly delayed with mean times of $39{\pm}11.2\;and\;48{\pm}17.1$ minutes respectively. The visualization of the gallbladder was demonstrated in 10 of 17 cases (59%) and occurred at $52{\pm}25.6$ minutes with a slight delay. The intestinal visualization occurred at $67{\pm}47.7$ minutes and was slightly delayed. $^{131}I$-rose bengal in the gallbladder remained high, $49.3{\pm}21.3%$, which suggested quantitatively decreased power of gallbladder constriction. 6. The time of the maximum hepetic uptake was correlated well to BSP retention and serum alkaline phosphatase ativity. However, the maximum hepatic uptake had no definite correlation with serum albumin, serum globulin, TTT, serum cholesterol, SGPT or SGOT. 7. In the diagnosis of the hepatobiliary diseases with jaundice, $^{131}I$-rose bengel serial scintiphotography has proved to be more useful than $^{198}Au$-colloid scintiphotography. With these results, it could be justified that $^{131}I$-rose bengal scintiphotography is an excellent diagnostic aid for dynamic hepatobiliary function studies in the clinical practice.

In an attempt to better understand the radioprotective effect of reduced glutathione(GSH), and to observe a possible radioprotective effect of Ginseng extract, whole body X-irradiation of 1,200 r was administered to the mouse either independently or immediately following the injection of GSH or Ginseng extract to the mouse intraperitoneally. The non-protein sulfhydryl (NP-SH) and non-protein disulfide (NP-SS) levels of the liver, and NP-SH level of NP-SH of the blood of the mouse were measured at 30, 60 and 120 minutes, and results were compared with the normal. The results thus obtained are summarized as follows; 1) The normal values of NP-SH and NP-SS of the mouse liver were $5.90{\pm}0.46\;{\mu}\;mol/gm\;wet\;wt.,\;and\;3.02{\pm}0.42\;{\mu}\;mol/ml$ wet wt., respectively, and the normal value of NP-SH of NP-SH of the mouse blood was $3.98{\pm}1.29\;{\mu}\;mol/ml$ 2) The injection of both GSH and Ginseng extract produced the highest values of NP-SH in the liver at 30 minutes, but a gradual decrease to the normal was observed thereafter. When X-irradiation alone was applied, the liver NP-SH value was lower than the normal at 60 minutes post-irradiation and thereafter. When Ginseng extract was injected immediately prior to X-irradiation, the liver NP-SH was lower than the normal throughout the experiment with the lowest value at 60 minutes. However, the combination of GSH and X-irradiation produced higher than the normal values throughout the entire experiment. 3) The liver NP-SS value was most significantly elevated at 30 minutes after the injection of GSH, hut the recovery to the normal was observed thereafter. The injection of Ginseng extract produced slightly higher liver NP-SS values at 30 and 60 minutes, but the value at 120 minutes was similar to the normal. The single application of X-irradiation resulted in the lower then normal liver NP-SS values throughout the entire experiment. When GSH was injected price to X-irradiation, the liver NP-SS values were higher than the normal at 30 and 60 minutes followed b the recovery to the normal at 120 minutes. The combination of Ginseng extract and X-irradiation showed generally lower liver NP-SS values throughout the experiment. 4) The blood NP-SH showed the higher than the normal values in all the experimental groups except when GSH was injected prior to X-irradiation alone produced e significantly elevated blood NP-SS value at 30 minutes post-irradiation.

This research focused on a total of 378 patients with external injuries under the age of 14 who visited the emergency center at a university hospital in Korea, during the months of January, April, August and November between January and December of 2007. In addition, the survey was conducted only on even number days and ranged across the whole year to reflect the impact of seasonal characteristics on the collected data. The research focused on determining the characteristics and inflicting cause of these patients with external injuries, analyzed the total time spent in the emergency room and obtained the following results. 1. When classifying the patients into different genders, the proportion of males (67.5%) was higher than that of females (32.5%). According to the different age groups, the highest ratio, at 61.1 %, was patients under the age of six. 2. Looking at the total number of minutes spent in the emergency room, the longest amount of time occurred during April with 162.7 minutes, followed by 121.9 minutes in January and 92.4 minutes in November. August had the shortest period of time spent in the emergency room, a significant statistical difference from the other periods of the year (p<0.001). 3. Regarding the amount of time required for each examination, patients required to provide a urine test spent an average of 204.7 minutes while those who did not spent 113.5 minutes on average. This is a 5% statistical difference among the two groups (p>0.05). 4. Looking at the five most commonly diagnosed problems in the emergency room, the total number of people with these top five commonly diagnosed illnesses comprised 55.6%, or 210 patients out of 378. 5. Utilizing the Decision Tree Model to estimate the total number of minutes required per visit, the first classifications were made using a chemical examination factor. People subject to chemical classification spent an average of 177.7 minutes, which was longer than the overall average of 115.2 minutes, and those exempt from chemical examination spent an average of 103.8 minutes, which was shorter than the average Conclusion; Effort to curtail the total time spent in emergency rooms is vital in guaranteeing efficient management of hospitals and providing medical services. The delay experienced by many comprehensive professional medical centers must be resolved through the establishment of effective delivery of medical services, increased supply of patient rooms and other policy oriented implementations. However, for now, this problem must be resolved by increasing the level of patient satisfaction and guaranteeing effective operation of patient rooms, which will significantly contribute to the general management and success of hospitals and institutions.

Recently, the number of diabetic patients have been increased with westernized living way and meal habitation. The regulation of blood sugar concentration is very important for diabetic patients to keep homeostasis and, to prevent acute or chronic complications. Epinephrine combined with lidocaine is used in dental clinic extensively. And epinephrine combined with lidocaine also effects on decreasing the blood leakage volume by constricting micro vessle and arteriole. But, So far there are few researches about the effect of epinephrine contained in dental local anesthetic agent on the blood sugar of diabetes during minor oral surgery. The purpose of this study was intended to investigate whether epinephrine which combined with dental local anesthetics influence body glucose level in diabetes patients by glucose monitoring. The subject of this study were 38 diabetic patients and 38 normal adults, each patient was checked body glucose after a meal 2 hours later with resting state, and injection 1:100000 epinephrine with dental lidocaine 54 ml or lidocaine 54 ml only. And then the body glucose level was checked 5 minutes and 30 minutes after injection. The results were analyzed by two way ANOVA test (p<0.05). The results were as follows: In the experimental group 1, the mean of the blood sugar level was 180.3 mg/dl before an anesthetic injection, 182.8 mg/dl after 5minutes of the anesthetic injection and 182.2 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the experimental group 2, the mean of the blood sugar level was 237 mg/dl before an anesthetic injection, 234.5 mg/dl after 5minutes of the anesthetic injection and 231.8 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 1, the mean of the blood sugar level was 117.6 mg/dl before an anesthetic injection, 119.1 mg/dl after 5minutes of the anesthetic injection and 129.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05). In the controlled group 2, the mean of the blood sugar level was 104.2 mg/dl before an anesthetic injection, 102 mg/dl after 5minutes of the anesthetic injection and 105.3 mg/dl after 30minutes of the anesthetic injection. The change of the blood sugar level was not statistically by two-way ANOVA tests (p<0.05).

Background : Theoretically as the waiting-time of patient is estimated in queueing, many men and much money are needed. But being the estimation of patient s waiting-time very important in hospital service, so the continuous monitoring of waiting-time is inevitable. To verify that the estimation of waiting-time using parking time is economical, effective and continuous monitoring method and to develop utilizing the method, this study was done. Method : In parking confirmation office, the personnel of parking office wrote parking confirm time, chart number and whether medical examination and treatment finish or not in parking ticket. The next day the parking tickets were gathered and the above data were input. The input parking data were connected with the hospital outpatient file indexing chart number. Then the patient' s data for department, new patient or not, reservation or not, receipt time and payment time were retrieved. The group for finishing medical treatment were compared with that for not finishing in average time lag between confirmation and out-time for hospital. And In-time for hospital, receipt time, payment and out-time for hospital were also analyzed. Result : Confirming parking ticket, the group for finished medical treatment left hospital after 7 minutes. This result showed that the patient for finished medical treatment left hospital immediately. So parking time was reasonable to estimation of hospital-time was concluded. The time for medical treatment, diagnosis and test was constant for all patients and short for waiting time, Then I concluded that the parking time was reasonable for estimation patient's waiting time. Overall patient's waiting time was 113 minutes and new patient's time was 149 minutes, old patient's times was 109 minutes. Waiting time for reservation patient was 98 minutes and for non reservation patient was 122 minutes. The time from hospital arrival to payment was 50 minutes for the group of reservation patient and 69 minutes for non-reservation group. The time from payment to hospital leaving was 51 minutes and 56 minutes for non reservation group. The short time difference between reserved group and not reserved group from payment to hospital leaving time was due to bottle neck effect. Conclusion : The estimation of patient's waiting time using parking time was reasonable because the possession of car was common and the time for medical treatment was equal and the patient after treatment left hospital immediately. Using this method, timely, fast evaluation and continuous monitoring of the intervention effect were possible.

1948년 제헌국회 성립 이후 오늘날까지 대한민국 국회는 의회 민주주의 제도를 수립하고 발전시켜왔다. 하지만 국회 회의록의 고유한 성격을 반영하는 관리제도가 정착되고 발전되기 위해서는 제도 및 운영적인 부분에서 아직까지 넘어야 할 산이 많다. 이에 본 연구는 의회제도에 대한 오랜 역사를 가진 주요 외국의 회의록 관리 사례와 국회 회의록의 관리사례를 비교 분석함으로써, 국회 회의록의 올바른 관리체계 및 개선 방안을 제시하고자 한다. 첫째, 국회 회의록의 효율적 생산 및 관리를 위한 행정조직 개편 방안의 심도 있는 논의가 필요하다. 둘째, 국회 회의록의 투명성을 보장하기 위해서는 법률을 근거로 하는 체계적인 관리가 필요하다. 특히 국회가 국민의 알권리 보장 및 민주주의 발전에 대한 선구적인 역할을 수행하기 위해서는 비공개 회의록에 대한 공개원칙을 재정립할 필요가 있다. 국회 회의록이 지니고 있는 다양한 형태와 가치, 그리고 특징은 국민의 대표이자 의회의 구성원인 의원으로부터 비롯된다고 할 수 있다. 따라서 국민에 의해 선출된 의회의 구성원으로부터 생산된 국회 회의록은 국민으로 하여금 적극 활용할 수 있게 해야 한다.
