The purpose of this study was to examine the trends of length of hospital stay (LOS), which is most likely to be a major attribute to hospital performance From 1984 to 1994, an average LOS of each hospital was analyzed by factors such as medical departments, bed size, occupancy rate, region and ownership. This study was analyzed changing rate of LOS during 11 years. This rate was calculated by simple regression, which was used only with hospital without missing data during 11 years. This study findings are as follows. 1. The results indicated that the average LOS was steadily increased until 1990 but it was slightly decreased after 1990. 2. This trend could be found in all hospital scale and all group of occupancy rate. Specifically this trends of LOS were found in internal medicine, corporate owned hospitals, and hospitals in major city. But LOS of individual owned hospital was continuously increased until 1994. 3. Means of changing rates of LOS were calculated from 1984 to 1994. If we divided it into two parts, before 1990 and after 1990, most changing rates of LOS before 1990 except individual owned hospital were found positive sign. The changing rates after 1990 were negative sign but small hospital(lesser then 200 bed), individual owned hospital, national & public hospital and hospital in small urban have little change of LOS after 1990. Finally from this results we thought that most hospitals in korea began to be concerned with LOS. Nevertheless LOS of several hospital such as small hospital or individual owned hospital was increased. And this trend may be caused by a few patients, low occupancy rate, or low profit. This trend of LOS is different from that of other countries. Perhaps this phenomenon is resulted from the reimbursement method. Because of fee for service reimbursement system in korea the hospitals didn't need to shorten LOS in order to save the cost and increase the profit. Therefore reform of hospital cost reimbursement method will be reduced to reduce hospital cost in korea. we thought that the korean health authority should consider the reimbursement method by unit of bundle of services, for example DRG and prepayment in the united states. This study presents some limitations such as on insight of severity of disease, case-mix measurement of hospital, and other clinical characteristics that can possibly affect LOS, However, this study reports an important trend in LOS from 1984 to 1994.

We report a case of acute intermittent porphyria presenting with variable symptoms and signs such as hypertension, polyneuropathy, syndrome of inappropriate secretion of antidiuretic hormone and cerebral infarction. A 47 year-old female patient entered hospital with abdominal pain followed by generalized seizure. She was diagnosed to have acute intermittent porphyria in consequence of Watson-Schwartz test and δ-ALA in 24 hours urine. She was managed with conservative treatment but died of respiratory failure.

Five cases of tennis elbow seen during the time period from Jaunary 1983 to January 1985 had operative treatment. Of the five clinical cases, four elbows in three patients were treated with Nirschl and Pettrone operation. This operative technique included exposure of the extensor carpi radialis brevis, excision of the identified lesion, and repair. The following results were obtained. 1. Correct analysis of the patient's emotional stability was essential prior to undertaking surgical procedure for tennis elbow. 2. The results of Nirschl and Pettrone operation were graded as excellent in three elbows and fair in one.

OBJECTIVES: This study was performed to compare health value cognition and health promotion behavior compliance between healthy group and not being healthy group, and to evaluate the difference of health promotion behaviors compliance between high group and low group in health value cognition. METHODS: The subjects of this study were 565 workers, 233 healthy workers, 172 observation cases and 160 disease cases, selected from 4,919 transit coporations workers. RESULTS: In health promoting behavior compliance, not being healthy group showed lower level than healthy group in exercise and showed higher level than healthy group in interpersonal support significantly. A worker who replied on health as the most value in life was consisted in 37.3% of healthy group and 36. 1% of not being healthy group, Health value cognition according to general characteristics showed no significant difference except only variable of age in healthy group. Health promoting behavior compliance according to cognition of health value showed in healthy group that a high level group of health value cognition was more significant difference than a low level group in self actualization and health responsibility of health promoting behavior and didn't show difference significantly in not being healthy group. CONCLUSIONS: In conclusion, the relationship between health value cognition, health promotion behavior compliance and periodic health examination results showed weakly. Therefore, in order to develop and apply spontaneous health promotion program, it was considered that should emphasize compliance than cognition.

Intraperitoneal hyperthermic perfusion(IPHP) is gaining popularity in the world as a method of prevention and treatment of peritoneal metastasis following gatrointestinal cancer. The procedure presents significant problems to the anesthegiologist with regard to tempera- ture control, fluid and electrolyte balance, acid-base change and postoperative care. During IPHP, there is a potential for heat gain from the peritoneal cavity. Several workers have reported a significant increase in core temperature. Therefore, it is true that accurate monitoring of temperature is essential. We studied that acid-base balance, electrolyte balance, level of blood suger following core temperature change in Intraperitoneal Hyperthermo-chemotherapeutic Perfusion patients.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Rips, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From March to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.
