Due to improvements in medical care, the socioeconomic level and public health, life expectancy has dramatically increased. Thus, advances in the development of life-support systems and the control of infection have resulted in many surgical and anesthetic procedures being performed on extremely elderly patients. In contrast to younger patients, elderly patients may manifest more than one pathologic process associated with progressive degenerative changes in various organs of the aged, espe- cially in the heart, brain, and kidney. Since both progressive degenerative change occuring in the elderly population and the cumulative incidence of disease in that population result in death intraoperatively or during the immediate postoperative period, the anesthesiologist must be particularly alert to the possibility of anesthetic risks in the elderly. The elderly patient is more likely to have hypertension, congestive heart failure, cardiac dysrhythmias, chronic pulmonary disease, and diabetes. Preoperative evaluation and treatment of those conditions must be extensively reviewed prior to the induction of anesthesia. To evaluate geriatric anesthetic experiences, 539 cases of patients aged over 60 years of 4,266 anesthetic cases admitted to P.M.C. from January to December, 1986 were analyzed according to age, sex, physical status, anesthetic technique an6 agents, surgical department, preoperative chest X-ray findings, preoperative E.C.G findings, and postoperative complica-tions. The results are as follows. 1) f 4,266 anesthetic patients 539(12.6%) were over 60 3ears of age and 322(59.7%) were males and 217(40.3%) females. 2) In the classification of physical status, the most common evidence was class 2 in 303 cases. Emergency surgery comprised 27.1% 1Yo. 3) The snesthesia technique employed was usually general anesthesia and this suggested that balanced anesthesia used with narcotics offers several advantages to geriatric patients. 4) In the surgical department, 310 cases(57.5%) were for general surgery, 75 cases(13,9%), orthopedic surgery; 57 cases(10.6%), urology; and 49 cases(9.1%), neurosurgery, respectively. Cancer was present in 198 cases(36.7%), 5) Preoperative chest X-ray findings: The most common finding was pulmonary tuberculosis in 44 cases(8.2%). Pneumonia, pulmonary emphysema, and so forth were also observed. 6) Preoperative E.C.G findings: The most common findings was myocardial ischemia in 48 cases(8.9%). Also myocardial infarction observed in 8 cases(1.5%) 7) Postoperative complications were as follows: The most common incidence was wourid infection in 29 cases(5.4%) followed by pneumonia. There were a number of miscellaneous complications. but postoperatively, they did not present any significant problems. 8) The overall mortality rate was 3.5%(19 cases). The difference in the mortality rate related to age was not statistically significant(p$gt;0.1), but the mortality rate related to physical status was statistically significant(p$lt;0.001). 9) Optimizing a patient's preoperative condition by the anesthesiologist, consultants, and other physicians was assumed to reduce perioperative morbidity and mortality.

This study was conducted to evaluate the Health Status of 584 students enrolled in WonKwang University by Cornell Medical Index Questionaire from March to May 1987. The conclusion is as follows ; 1. Inaducacy, eyes and ears, fatigue in CMI items was showed high Complaints rate of more than 30% 2. For the purpose of understanding the Health Problem according to the general characteristics of students implemented Analysis of Variance Test. The results that according to sex, age, marital status, income, native place, medical institution looking for firstly, college are significant difference appeared. 1) Sex ; Female students shows higher complaints rate than male students. 2) Age; The younger, the higher complaints rate appeared. 3) Marital Status ; Single shows higher complaints rate than married. 4) Native Place ; Students who grown in middle, small city and large city shows higher complaints rate than rural students. 5) College ; Medical college, the others (humanistic, sociological arts college), Herb medical college, in regular sequence high complaints rate appeared.

Because offshore structures are affected by various environmental loads, the risk of damage is high. As a result of ever-changing ocean environmental loads, damage to offshore structures is expected to differ from year to year. However, in previous studies, it was assumed that a relatively short period of load acts repeatedly during the design life of a structure. In this study, the residual life of an offshore wind turbine support structure was evaluated in consideration of the timing uncertainty of the ocean environmental load. Sampling points for the wind velocity, wave height, and wave period were generated using a central composites design, and a transfer function was constructed from the numerical analysis results. A simulation was performed using the joint probability model of ocean environmental loads. The stress time history was calculated by entering the load samples generated by the simulation into the transfer function. The damage to the structure was calculated using the rain-flow counting method, Goodman equation, Miner’s rule, and S-N curve. The results confirmed that the wind speed generated at a specific time could not represent the wind speed that could occur during the design life of the structure.

- In this paper, we investigated the selective etching rate of amorphous As-Ge-Se-S thin film due to the photoexpansion effect and fabricated the 2-dimensional embossing type diffraction grating hologram. We measured the thickness change with the etching time among NaOH solution after forming 1-dimension diffraction grating. As a results, we found that the selective etching rate were 2.5Å/s, 3.3Å/s, 3.9Å/s where NaOH solution concentration were 0.26N, 0.33N, 0.36N, respectively. Also after the formation of 2-dimensional diffraction grating by the 90˚ degree of circulation on the formed 1-dimensional diffraction grating, we etched selectively during 60sec, among 0.26N NaOH solution and obtained 2-dimensional embossing diffraction grating. As the results of AFM (Atomic Force Microscopy), we confirmed the formation of distinct embossing type 2-dimensional diffraction grating hologram, successfully.

Recently, halothane has been commonly used as an inhalation anesthetic agent, but it is generally accepted that it can cause postoperative hepatic dyfunction. Therefore, other anesthetic agents which have relatively less hepatotoxic effects have been recommended. This study was undertaken to evaluate the postoperative hepatic changes in patients with abnormal liver function or hepatobiliary diseases. Patients were divided into three subgroups: hepatobiliary, other hepatobiliary and jaundice, or HBsAg(+) for the two ansethetic agents, enflurane and Thalamonal. Liver function tests were performed before surgery, and on the 3rd, 5th and 9th postoperative days. The results were as follows: 1) SGOT and SGPT showed a more statistically significant decrease in Thalamonal anesthesia than in enflurane anesthesia in hepatobiliary and jaundace or HBsQg(+) groups. However, in the other hepatobiliary groups, there were no significant differences between the anesthetics. 2) Total protein, albumin, total bilirubin, direct bilirubin and alkalin phosphatase levels were not shown to be significantly different between the use of the two anesthetics in all groups. It is suggested that postoperative hepatic changes may have improved more significantly in Thalamonal anesthesia than in enflurane anesthesia in hepatobiliary patients with abnormal liver function and jaundice or HBsAg(+) patients.
