This study was conducted to examine the differences of the quality of chest compression between 10 cm higher position of rescuer's knee from the bottom and its bottom position during implementation of CPR. It selected randomly subjects out of 66 students who attend the Dept. of Emergency Medical Technology in G college, G metropolitan city as the first grader and divided them into 31 experimental group and 32 control group from Nov. 8 to 9, 2011. Mattress was spread 10 cm higher from the bottom(material: B4 Copy Paper) and on the bottom(material: PVC, size: $185{\times}125{\times}0.65cm$) and only chest compression was conducted for 2 minutes. Experiment was conducted with 1 Resusci Anne mannequin and the results of experiment were recorded with Laerdal PC Skill Reporting System. Data collected were analyzed with $x^2$-test and Fisher's exact probability test using SPSS 14.0 for Window, Mann-Whitney U-test, and Wilcoxon signed rank test. As a result of the study, it was found that 10 cm higher position of rescuer knee from the bottom than the bottom position and group below 170 cm in their height and 65 kg in their weight were more effective in proper depth of chest compression and average chest compression depth.

A 51 year-old male was admitted with the chief complaints of swallowing difficulty and pain on neck and upper chest for 2 months prior to admission: He was taken biopsy under esophagoscopy, and the result was squamous cell carcinoma. Preoperatively we studied the esophagogram and chest CT. On these, we found the main appreciable mass at midesophagus easily. But, we missed the upper cervical unexpected mass. So we performed the esophagectomy and lymph node dissection from upper clavicle level to the esophagogastric junction by thoracic approach as wide as possible, and cervical esophagostomy and feeding gastrostomy also. At that evening we reviewed the studied films in detail, and we found another mass lesion at C4-C6 level of cervical esophagus. We performed the 2nd operation e.g. cervical esophagectomy on next morning without hesitation. Between these two masses, there was almostly normally looking skip area grossly. The squamous cell carcinoma of the esophagus could be multicentric in character and may have skip area. But, we heard little reports until now. The two masses could be different in origin or be same probably by submucosal spreading. Anyway, it was an alarming case to the surgeon not to neglect the another possible lesions in squamous cell type. Postoperative course was uneventful, he took G-tube feeding with no problems on 7th postoperative day. Now he took the postoperative irradiation at out patient department.

Background: Lung transplantation is the definitive therapy for end stage lung disorders. The success of allogenic lung transplantation has led to an increasing shortage of donor lungs from humans, including cadavers, and attention has now turned to transplantation of lungs from other species. However, there are many biological hurdles when using organs from other species because of hyperacute rejection after discordant xenotransplantation. Material and Method: Pigs (n=6, weighing $20{\sim}30kg$ each) for the donors and mongrel dogs (n=6, weighing $20{\sim}28kg$ each) for the recipients were used in this experiment. The left kidney of a pig was perfused to a mongrel dog for 30 minutes through the femoral artery and vein of the dog, and the right kidney was perfused for 30 minutes sequentially. Then, both lungs of the pig were perfused to the dog through the pulmonary artery and left atrium with using the same time intervals. The levels of IgM and IgG were measured from the blood and specimens of the kidney and lung. Result: The average levels of serum IgM gradually decreased after the perfusion, but the average levels of serum IgG did not charge from before to after perfusion. The immunohistochemical findings revealed decreased deposition of IgG and IgM after the perfusion. Conclusion: We conclude that the levels of the serum natural antibodies would be decreased with pre-transplantation xenograft perfusion in the recipient and the occurrence rate of hyperacute rejection after transplantation would be decreased.

The purpose of this study was to increase accuracy in performing cardiopulmonary resuscitation through comparing accuracy between chest compression and artificial respiration depending on position, gender, and weight of a victim given conducting cardiopulmonary resuscitation. This study randomly sampled 72 college students in G Province (36 in the experimental group and 36 in the control group) to conduct a research from November 5 to 19, 2009. The collected data were analyzed by using an SPSS WIN 12.0 Version program. Since the results showed that most regions got more effective artificial respiration and chest compression on the right side than on the left side, it is necessary to apply cardiopulmonary resuscitation on the right side in terms of how to implement and instruct cardiopulmonary resuscitation in the future. However, it seems that continuous researches are necessary to see if cardiopulmonary resuscitation is more effective on the right side in terms of the survival rate in an actual emergency.

To evaluate the health status of the aged in rural area, 476 men and women of 65 years old and older among the residents of Gunwee County in Kyungpook were examined at the county health center between 4th and 22nd of June, 1984. Physical examination included measuring height, weight, chest circumference and blood pressure and chest x-ray. Laboratory tests were done for serum cholesterol, glucose and GOT, and urine glucose and protein. The mean heights of male and female were 160${\pm}$7.0cm and 147.7${\pm}$6.9cm, respectively. The height decreased as the age increased. The mean body weight of male was 53.5${\pm}$7.8kg and 46.7${\pm}$7.5kg for female and the older, the eighter. The mean chest circumference of male was 85.4${\pm}$7.5cm and 79.5${\pm}$79cm for female and it had no remarkable differences by age group. The average height, body weight, chest circumference, and serum cholesterol level of the age 65 years and older in rural area were lower than the standard this may be due to undernutrition of the aged. The mean diastolic and systolic blood pressure of male were 75.9${\pm}$13.5 mmHg/126.3${\pm}$24.1 mmHg and those for female were 73.1${\pm}$13.9 mmHg/125.8${\pm}$32.4 mmHg. Both male an d female in the age group of 65-69 years showed the lowest mean blood pressure. Among the study population 18.3% the borderlin hypertension and 14.3% had hypertension. Average hemoglobin level of the male(12.5${\pm}$0.8 g/dl) was higher than that of the female(11.6${\pm}$0.8 g/dl) (p < 0.01). Mean serum G.O.T. level was 25.2${\pm}$8.7 IU for male and 23.6${\pm}$7.5 IU for female and all of the study population were within the normal range. Mean serum glucose level was 110.4${\pm}$16.0 mg/dl for the male and 110.5${\pm}$15.7 mg /dl for the female and 41.4% of the study population were above the normal limit of serum glucose level. However, there was only one person she had glycosuria. Hyperglycemia could be due to non-fasting before the test. Two of the study population had proteinuria and five persons (1.05%) were diagnosed as pulmonary tuberculosis by the chest x-ray.

The purpose of this study was to analyze and compare head register with chest register of singers acoustically. Fifteen healthy tenor major students were participated. Fifteen healthy untrained adults were chosen as the control group for this study. Long term average (LTA) power spectrum using the Fast Fourier transform (FFT) algorithm and Linear predictive coding (LPC) filter response were made with /a/ sustained in both head (G4, 392 Hz) and chest registers (C3, 131 Hz). Statistical analysis was performed using the Mann-Whitney test. In the LTA power spectrum, head register of singers increased in the level of energy gain within the frequency of 2.2-3.4 kHz (p<0.01), and 7.5-8.4 kHz (p<0.01, p<0.05). Chest register of singers increased in the frequency of 2.2-3.1 kHz (p<0.01), 7.8-8.4 kHz (p<0.05) and around 9.6 kHz (p<0.01). The LTA power spectrum revealed a peak of acoustic energy around 2,500 Hz, known as the singer's formant and another peak of acoustic energy around 8,000 Hz in the singer's voice.
