Purpose: This study aimed to analyze the impact of rapid cycle deliberate practice (RCDP) simulation education on advanced cardiac life support knowledge, confidence, satisfaction, and performance ability among paramedic students, and provide basic data on the appropriate methods of educational instruction. Methods: The 48 subjects to be instructed were divided into the traditional simulation education group and the RCDP simulation education group. Six participants were randomly assigned to each group and pre-surveyed. They were then exposed to a lecture about advanced cardiac life support related theories for 60 min and post-surveyed through questionnaires with the same learning goals and scenarios. Results: The advanced cardiac life support knowledge (t=-4.813, p=.000) and performance ability (t=-2.903, p=.006) were significantly different between the traditional simulation education and RCDP simulation education groups The results also showed a significant difference in attach monitor (z=6.857, p=.009), analyze EKG rhythm (z=11.111, p=.001), and defibrillation (z=12.632, p=.000), indicating differences in performance capabilities between the two groups. Conclusion: To improve advanced cardiac life support knowledge, performance ability, and confidence in the paramedic students who receive RCDP simulation education, simulation education methods that are appropriate for the subjects being taught, and detailed learning goals and feedback are necessary.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in three patient groups with arrhythmia(AP group), with arrhythmia and cerebral infarction(CI group), and with arrhythmia and hemorrhage(CH group), and then to find out the characteristic of meridian system among 3 groups. Methods : Thirty arrhythmic patients diagnosed by EKG, CT, and deficiency of the heart blood(心血虛症) were divided into 3 groups(AP, CI, CH group). Their electric potential of well and sea points in the meridians were measured 3 times by physiograph. Results : Measurements were analyzed by statistical factor analysis, we obtained that the left side electric potential of well and sea points in branches of the twelves meridians in AP group was divided into two factors, which were the hand meridian without the lung meridian, the foot meridian and the lung meridian, but the right side electric potential was divided into the hand and the foot meridian. In CH group both the left and the right side electric potential was divided into three factors. In CI group the left side electric potential was divided into three factors, but the right side electric potential was divided into two factors. Conclusions : In conclusion, their electrical potentials were different each other among 3 groups. Thus electrical potentials of well and sea points might be the representative meridian to show their characteristics.

Truncus ateriosus is one of the cyanotic congenital heart disease. The incidence is relatively uncommon, as 0.4% of totoal congenital heart disease. Embryologically the defect is due to a lack of partitioning of the embryonic truncus and conus during the first few weeks of fetal life. The ventricular septal defect is invariable present. A single arterial vessel arises from the heart and supplies blood to the aorta, the lung, and the coronary arteries. In 1949, collett and Edwards classified this defect according to anatomic variation to four major types, such as type I, II, III, and IV. Type IV is defined that pulmonary arteries are absent, and the pulmonary arterial supply arises from the descending thoracic aorta. This patients often have a continuous murmur head particularly well in the interscapular area. No effective surgical treatment is available. We have experienced one case of truncus arteriosus, type IV of Collett and Edwards in the Department of Thoracic and Cardiovascular Surgery, Kyungbook National University Hospital. This patient was 10 year-old girl. The chief complaints were cyanosis and dyspnea on exertion since birth. She was admitted at this hospital on April 16, 1980. The continous machinery murmur was heard loudest at the interscapular area. The chest X-ray films revealed cardiomegaly with an increase in pulmonaryvascular markings. The pulmonary secotr was significantly concave. No filling of pulmonary arteries noticed by the right ventriculogram. There was possible biventricular hypertrophy in EKG. The echocardiogram showed that the demension of the aortic root was larger than normal and minimal increase of the left ventricular internal dimension. The cardiac catheterization data was obtained by use of the great saphenus vein approach. The systolic pressure of the right ventricular outflow tract was 80 mmHg and was similar to that of the aorta. The oxygen saturation data revealed the evidence of the left to right shunt at the level of ventricular septum. The patient was operated and the diagnosis was confirmed as trucus arteriosus, type IV. No effective surgical interventins were performed.

The electrocardiogram of frogs were obtained in winter (January), spring (April), summer (July) and autumn (September and November). Electrocardiograms were recorded applying electrodes to the atria, ventricle and apex of the heart by unipolar or bipolar leads. V wave was recorded prior to P wave, for the presence of the sinus venosus which controls the automaticity of the frog heart, in four seasons. Regardless of the leads or the position of the electrodes P wave was diphasic and wide. According to the rise of temperature the rate of heart beat was increased, and V-P and P-R interval were shortened. Two regression line between R-R interval and both V-P interval and P-R interval were drawn. These were calculated as V-P interval=1 0.276R-R $interva1+0.067{\pm}0.15$ (sec.) and P-R interval=0.179R-R $interva1+0.155{\pm}0.1$ (sec). From these calculation the larger gradient of V-P interval than P-R interval was suggestive that the heart rate is more dependent on the changes of V-P interval than that of P-R interval. Changes of the heart rate were also measured in four seasons and artificial temperatures. Two regression lines between the heart rate (H.H.) and both seasonal temperature (T) and artificial temperature, were drawn. These two lines were calculated as H.R.=20+3.71 (T-10) and H.R.=32+1.425 T respectively. From two gradients of the above equations it is considered that the changes of the heart rate in artificial temperature were milder than that in seasonal temperature. The number of RBC and WBC of frogs were measured in four seasons and a tendency of the changes was observed according to the seasonal variation.

The objective of the study was to evaluate the efficacy of a health check-up program among Thai people at the National Cancer Institute in the years 2008-2009. The program included history taking, physical examination, chest X-ray, EKG, and laboratory tests. A total of 28,240 women and 9,665 men were included in the study, with mean ages of 44.5 and 46.9 years, respectively. The study showed that obesity, as assessed by a BMI over 25.0 kg/m2, in men and women was present in 41.4% and 30%, respectively. Biochemical study revealed that anemia was prevalent in 21.6% of men and 20.1% of women. High plasma glucose level (>115 mg/dL), cholesterol level (>200 mg/dL), triglyceride level (>190 mg/dL) in men was 13.8%, 63.8%, 22.6% and 7.7%, 61.1%, 8.9% in women. Hepatitis B virus infection was found 7.5% in men and 4.1% in women. In this study, 177 new cancer cases were detected, of which 35 were breast, 19 were cervical and 26 were colorectal, most of these cancers being detected at early stage. In addition, precancerous states was also found including 718 cases of benign and 99 cases of adenoma in situ. In conclusion, an annual check up may detect abnormalities that have no obvious clinical symptoms of disease. Early detection of asymptomatic neoplasms and precursor lesions should contribute to a prompt provision of treatment and further decline of death from cancer.

Many patients with intractable chest pain visit pain clinics, two of which, with rare cases of an intraspinal tumor and malignant mesothelioma were experiences at our clinic. A 37-year old female patient presented with exacerbating chest pain, but without neurological manifestations, of 15-months duration. Her laboratory findings, such as blood tests, chest X-ray, EKG, abdominal ultrasonography and chest CT, were normal. MRI revealed an intradural extramedullary schwannoma at the T 5 and 6 levels of the thoracic spine. She completely recovered following a laminectomy, with removal of the tumor. The other case was a 65-year old male patient, who presented with chest and back pain in the thoracic area of 6 months duration. He had no cough and dyspnea, and was initially misdiagnosed with intercostal neuralgia; therefore, pain control medication was administered, but all trials were ineffective. Finally, chest CT revealed a malignant mesothelioma, with multiple spine metastases. In conclusion, patients with intractable chest pain should be re-examined both clinically and radiographically.
