To identify the factors influencing the charges per case of acute appendicitis and normal spontaneous vaginal delivery (NSVD), the personal data-base files and hospital-characteristics-reporting data files of Korea Medical Insurance Corporation were analyzed. One hundred and twenty-nine institutions were selected. The results of this study were as follows: 1. The differences of charges per case with respect to hospital ownership, location, and equipment levels were statistically significant. 2. The results of multiple regression analysis revealed that bed capacity was the most significant variable in both diseases. 3. Ownership was significant variable in acute appendicitis. In NSVD, ownership and hospital equipment level were statistically significant. In conclusion, bed capacity was statistically the most significant variable in the analysis of charges per case. And we thought that the results of this study would influence the policy of the hospital bed supply.

Laparoscopic cholecystectomy was introduced into Korea in 1990 and has been rapidly replacing open cholecystectomy when the indications were met. In this study a medical utilization and technology was assessed on the selected hospitalized patients with cholelithiasis who underwent open or laparoscopic cholecystectomy from April 1, 1991 to March 31, 1994. The results are as follows. Despite the low reimbursement rate by the health insurance, the number of laparoscopic cases have been steadily increased. The post-operative days before health insurance coverage were significantly shortened from 8.4 days to 4.6 days. The preoperative days before health insurance coverage were significantly shorted from 8.4 days to 4.0 days. The total length-of-stays in the hospital were also significantly shortened from 15.2 days to 10.7 and 9.8 days in laparoscopic cholecystectomy. The laparoscopic cholecystectomy showed low expenses in all aspects expect the average hospital charges per day. For the hospital to have cost containment, it is more effective if length-of-stay is shorter because of high daily inpatient hospital charge. The laparoscopic cholecystectomy also showed shortened anesthesia time and operation time compared with open cholecystectomy that were statistically significant. The mean anesthesia and operation time for open cholecystectomy were 113.2 and 90.2 minutes but those of laparoscopic cholecystectomy were 105.7 and 68.6 minutes. According to this study the laparoscopic cholecystectomy has reduced the medical expenditure and we recommend this procedure over open cholecystectomy. The further discussion on the different morbidity rate between two types of procedure is essential in providing quality medical care, and to educate specialist.

In recent years, the Korean Medical Association has undertaken the feat of establishing the Korean Standard Terminology of Medical Procedures with the dedicated help of 32 medical academic societies. However, because the project is being conducted by several different circles, it has yet to see a clear system of classification. This thesis, therefore, proposes the three principles of scientific properties, usefulness and ideology as the basis for classification system and has developed the Classification System of Medical Procedures in Korea upon their foundation. The methodology and organization of this thesis as follows. First, by adopting scientific classification system of Feinstein(1988), an analysis of the classification systems of the medical procedures in the United States, Japan, Taiwan, Who Was carried out to reveal the framework and the basic principles in each system. Second, the direction of classification system has been constructed by applying the normative principle of medical field in order to show the future direction of the medical field and realize its ideology. Third, a finalized framework for the classification system will be presented as based on the direction of classification system. Of the three basis principles mentioned above, the analysis on the principles of usefulness was left out of this thesis due to the difficulty of establishing specific standards of analysis. The results of the study are as follows. The overall structure of the thesis is aimed at showing the 'Prevention-Therapy-Rehabilitation' quality of comprehensive health care and consists of six chapters; I. Prevention and Health Promotion. II. Evaluation and Management . III. Diagnostic Procedures. IV. Endoscopy. V. Therapeutic Procedures. VI. Rehabilitation. Chapter three Diagnostic Procedures is divided into four parts; Functional Diagnosis, Visual Diagnosis, Pathological Diagnosis, Biopsy and Sampling. Chapter five Therapeutic Procedures is divided into Psychiatry, Non-Invasive Therapy, Invasive Therapy, Anaesthesia and Radiation Oncology. Of these sub-divisions, Functional Diagnosis, Biopsy and Sampling, Endoscopy and Invasive Therapy employs the anatomical system of classification. On the other hand, Visual Diagnosis, Pathological Diagnosis, Anesthesia and Diagnostic Radiology, namely those divisions in which there is little or no overlapping in services with other divisions, used the classification system of its own division. The classification system introduced in this thesis can be further supplemented through the use of the cluster analysis by incorporating the advice and assistance of other specialists.

A study of the knowledge, attitude and practices about the maternal and child health of 305 married women residing in apartments at the Yonsei community Health area was conducted during the period from November to December 1970 using designed questionnaire with well trained interviews. The results and findings obtained from the study are summarized as follows : A. Pregnancy and Birth. Questions were asked about their last child. 1. 16.4% of the women were pregnant. 2. Among 281 women who hand experienced delivery, 48.0% were assisted by doctor or midwives for their last delivery, while the rest of women delivered their last baby at home without any professional's assistance. The higher the level of education or the greater exposure to mass communication, the more the deliveries were assisted by doctors or midwives. Those women who were born and raised in cities had more deliveries assisted by doctors and midwives than those who were not. 3. Kinds of delivery sheets used. Among 141 cases of home delivery 68% used cement bag paper or vinyl sheets. Three% used nothing and remained used unsterile materials. 4. Among 141 cases of home delivery, 70.2% used scissors. The rest of them used other methods. 5. 47.3% of the women had a rest for one month or more after birth. The higher the level of education, the longer the period of rest was observed. 6. 52.4% of the women fed the colostrum to their babies. This was not related to the mother's education. 7. About half(42.9%) of the women had poor knowledge about a proper diet for the pre and post natal period. B. Child Health. 1. Knowledge and practice regarding to the immunization for their children : Most of the women (93.2%) could name at least one kind of immunization. 20.3% could name 6 kinds of immunization. Mothers education level did not influence their ability to name immunizations. 85.2% of children had been immunized at least once. 2. Morbidity of last born children : 48.1% of their last born children were found to have been sick during the last year. Less than half (41.5%) of the sick children were seen by doctor. 3. Counselling at well baby clinic : most of the women (76.5%) had no counselling for their children. Registration rate at the well baby clinic at the Severance Hospital was 13.2%. 45.9% wanted to visit to the well baby clinic at the Severance Hospital. 4. Weaning Period : 44.6% said that the beginning of the weaning for their last born children was from 6 months to twelve months of age. The most important reason of weaning was the health of both mothers and children. 5. Knowledge and Practice regarding birth and death Registration : 64.6% of the women could name correctly the Ku-office as the place for the registration. Only 29.2% registered the birth of their last born children within 14 days. C. Knowledge, Attitude and Practice regarding to family planning Most : of the women accepted the idea of family planning. 97.7% could name at least one contraceptive method. 35.4% were found to be current users of countraceptive methods. The ideal number of children was 3.1 in average.

OBJECTIVE: Various lesions including tumors occupying in the presellar and suprasellar regions have been traditionally removed by the transcranial approach. The new modified transsphenoidal approaches(TSAs) have been proposed to avoid the craniotomy and to get better surgical view. MATERIALS AND PATIENTS: The sellar floor and presellar anterior cranial fossa were removed through the sublabial transseptal transsphenoidal technique in the "transsphenoidal supradiaphragmatic intradural approach". One tuberculum sella meningioma and a suprasellar Rathke's cleft cyst confined to the pituitary stalk were removed via this approach. RESULTS: The dissection of the anterior intercavernous sinus, diaphragma sella, and arachnoid membrane allowed a wide surgical field of pre- and suprasellar areas and facilitated a safe removal of lesions without significant surgical complications in our cases. CONCLUSION: From the authors' limited experience, the advantages of this technique are as follows: 1) it can be easily applicable through a minor modification of the standard TSA, 2) excellent anatomical exposure of the structures located in the supradiaphragmatic suprasellar cistern, and 3) might be suitable to remove small lesions located in the presellar and adjacent to the pituitary stalk region.

A postal survey was conducted to obtain information of the Protestant minister's knowledge, attituedand practice about family planning sex education and marriage during the period of July and August 1970. 536 ministers(14.4% were randomly selected from the nine denominations and military chaplains for the study using the most recent directories. Among 536 ministers 406 (75.7%) sent back the questionnaires. The knowledge about family planning was relatively higher than expected. In contrast to their higher knowledge, their approval rate of the family planning was slightly lower than that of the general population. The main reason for not approving of family planning was religious. The most commonly used contraceptives of the ministers were the traditional methods. The age of the ministers is the most important factor influencing their attitude toward family planning and sex education. The younger ministers tend to show more positive attitudes toward family planning and sex education. The denominations are also important factors influencing the attitudes and knowledge about family planning and sex education. Most ministers, particularly younger ministers, were dealing with sex problems in someway in church services. About one third of the ministers were dealing with sex education very actively in church services. Many ministers showed very liberal attitudes about marriage. The most important factor for selecting a daughter or son-in-law was their religious belief.

PURPOSE: To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. MATERIALS AND METHOD: A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. RESULTS: Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. CONCLUSION: MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

In an attempt to understand the changing pattern of hospital care utilization and costs, a study was made of the medical and administrative records of 7,798 patients, who were discharged from a private, university teaching hospital in the years 1955, 1960, 1965, 1970 and 1974. An analysis of the ages of the patients who utilized the hospital, revealed little change over the study in the age distribution of female patients, but did show increases in the percentages of male patients who were under 5 and over 60 years of age. The overall average length of stay in hospital decreased continuously, from 17.1 days in 1955 to 10.4 days in 1974, and the average length of stay of those who were discharged within 90 days of admission decreased from 14.4 days in 1955 to 8.9 days in 1974. Patients who received surgical treatment remained in hospital for three to four days longer than did those who received non-surgical treatment. Obstetrical cases remained in hospital for 6.9 days in 1955, and 4.8 days in 1974. A large majority of the patients (87 - 96%) were discharged within one month of admission, and virtually all (97.5 - 99.4%) within three months. In respect to the place of residence of the patients, the data revealed that 80% were from Seoul Two-thirds of the patients from Seoul resided in districts immediately surrounding the hospital, showing that despite increasingly effective transportation facilities, hospital utilization continued to be localized to people living in areas near the institution. The study revealed little change in disease patterns over the years: the percentage of obstetrical admissions remained highest with infectious and parasitic diseases, gastrointestinal diseases, injuries, neoplasms and respiratory diseases ranking in descending order. The status of patients at time of discharge showed improvement: the recovery rate increased, and the proportion of patients who died decreased. Total hospital expenses increase 4.4 times and expenses per patient day increased 6.2 times, both results having been determined through the use of constant market prices. It is considered that the latter increase resulted primarily from intensification of medical care and shortening of the hospitalization period. Among the various components of hospital care costs, room (hotel-type) and treatment expenses remained at approximately 40%of the total, while expenses for drugs and injections were approximately 20% in each of the five years of the study. Study of the relative increase of hospital costs by component of care revealed that the highest. increases over the twenty-year period was in the cost of laboratory services, followed by drugs and injections. It would seem that these high increases resulted from rapid technological developments in diagnostic and therapeutic procedures.

Since nationwide compulsory health insurance started in 1977, shortage of hospital beds has become apparent and this is related in part to the length of hospital stay. To determine the factors which affect the length of stay a total of 1,003 in-patients medical records for appendectomy, cholecystectomy, and Cesarean section discharged in 1965, 1970, 1975 and 1980 from a university hospital were studied. The major findings are as follows; The average length of stay showed a statistically significant difference by year among the cholecystectomy and Cesarean section patients. For the appendectomies no statistically significant difference was found. Complications after surgical operation explained the length of stay mostly in all three procedures; the next factors were age, character of surgery, day of the week of surgery, and multiple diagnoses in this order for appendectomy; day of the week of surgery, age, type of accommodation, route of admission in this order for cholecystectomy; and day of the week of surgery, multiple diagnoses, residential area and type of accommodation in Cesarean section respectively.
