  • The purpose of this study was to verify the difference in biomechanical variation and pattern of the lower limb between planned and unexpected termination, which is related to the prevention of fatal fall in the elderly. Therefore, selected twenty subjects for each group which composed of females(age: $73.5{\pm}4.63$ year, height: $153.2{\pm}6.46$ cm, body mass: $58.98{\pm}5.82$ kg) and women(age: $23.4{\pm}2.5$ year, height: $164.65{\pm}3.9$ cm, body mass: $58.47{\pm}5.53$ kg) in their twenties. As a result, lower limb's extension moment and power were increased significantly in statistics(p<.05). Also, knee joint power showed instant changes from concentric contraction to eccentric contraction and hip joint power from eccentric contraction to concentric contraction. During unexpected termination there were dramatical increase in eccentric contraction and power(p<.05). In both planned and unexpected termination, ankle joint moment were higher in young group, but the moment of the hip joint were higher in the elderly group(p<.05). In contrast to younger group, there were no changes in knee extension moment in elderly group(p<.05). but showed relatively higher hip joint extension moment and power(p<.05).

  • This study was prospectively planned to realize the reduction of calcium ion in serum along with the cardiopulmonary bypass[CPB], to find out the cause of the reduction, and to verify the justification of the classical methods of calcium replacement. Nine patients with various open heart surgeries by CPB in 1987 wee selected at random. Calcium chloride was added as follows:: For each unit of ACD blood transfusion, 600mg of calcium chloride was added. In case of massive transfusion, 600 mg of calcium chloride was injected every 2 or 3 units of transfusion. On occasions such as weaning from CPB, or following defibrillation, or hypotension, weak myocardial contractility of the heart, calcium chloride was needed in an amount of 10 mg / kg. In ICU, calcium chloride was limited to use in low serum level or in emergency use. Total calcium decreased early bypass and progressively increased above the preoperative value during late bypass and three hours thereafter, Ionized calcium increased during late bypass and three hours following. Total and ionized calcium depicted similar patterns of change during open heart surgery. Decrease of the calcium at the early bypass was thought from reduction of total protein and alkalosis during bypass. Meanwhile, increase of both calciums during the end of surgery was presumably attributable to addition of calcium chloride in priming solution, injections of calcium chloride in the process of termination of bypass. We conclude that enough calcium was replaced by the classical methods of calcium supplement.

  • Purpose: The purpose of this study was to analyze the differences in terms of services and cost between CVA without typical diseases (Group I), and CVA with typical diseases (Group II), in their Hospital-based home health care. Method: The subjects of this study were 308 CVA patients who used home care nursing during the second phase demonstration project of their hospital-based home health care. Results: The results of the study was as follows 1. Group II had more home visit (15.3/12.7) (p>0.05), and cases of death when home care (16.8/11.4) (p<0.05). 2. Group II needed more services than Group I such as bladder irrigation, skin care, bed sore care, glycerin enema, finger enema, lung care, urine sugar test, monitoring and surveillance of fluid infusion and R.O.M exercise (p<0.05). 3. The variables that showed statistical significance in the regression analysis were family style, OPD visit, level of consciousness, patient's state on termination of home care, and some extend of home health care services (R2=0.373, 0.205). Conclusion: Home nursing care needs to be planned by severity in Hospital-based home health care for CVA patients.

  • The purpose of this study is to develop the group program model for reinforcing family relations of single-mother families as one approach to family welfare service. As previous research findings about problems of single parent families were reviewed and the framework for the program development was identified, a 6 sessions group program was planned and applied to 9 single-mother families from June 2nd to July 7th. Program evaluation questionnaire, Scales measuring powerlessness and FACESIII for family relations, social support network tool, and group process recording were used for the evaluation of this program. The participants evaluated this program as very supportive, useful, and educational. The powerlessness was reduced in a statistically meaningful way before and after the program and the result was found to be maintained for 4 months in the follow-up session. The family relations according to FACES III were mostly balanced and didn't show some significant change after the termination of this program. The single mothers had little concrete supports from others, if any, had some from relatives. They rather had to give supports for the other family members and reciprocally gave and took emotional or informational supports with friends or neighbors. Based on these results, the 2 step model consisted of brief group program and long term support group was developed and the practical methods were suggested for the single-mother families with low income.

  • A study was planned to see if the Panax Ginseng has any influence upon the general activity of rats. Seventeen male rats (mean body weight: 204 g) was divided into a ginseng group (N=9) and a saline group (N=8). Once a day for 5 days they received subscutaneously 0. 5m1/100g body weight of ginseng extract solution (4 mg of ginseng alcohol extract in 1 ml of saline), and same amount of saline, respectively. For 20 days beginning from the 1st day of medication on, each rat received activity measurement by means of beam interruption method. Following results were obtained : 1. Activities at night (6 p.m. to 6 a.m. next morning) and in 24hours on the 10 th, 12th, and 13 th day were significantly increased in the ginseng group compared with activities of the saline group. 2. Summed total night and 24-hour activities observed for 15 days after termination of medication were also significantly augmented in the ginseng group compaired with those of the saline group, although no remarkable difference existed between the 2 groups with regard to the summed total daytime activity. It is inferred that the ginseng augments general activity of rats especically at night.

  • This paper is aimed to analyse the recent changes in family planning as a step in an evaluation of the results of the population control policy which has been strenuously pursued by the government since December 1981. The data used in this analysis comes from the 1985 national fertility and family planning survey conducted by the Korea Institute for Population and Health (KIPH) in May 1985. According to the 1985 survey data, there have been great changes in both the contraceptive practice and fertility rates since the strengthening of the government's population control policy in 1 981. The contraceptive practice rate for married women aged 15-44 has increased from 57.7% in 1982 to 70.3% in 1985, an increase of 12.6% points in the short span of only 3 years. During the same period, the total fertility rate has declined from 2.7 in 1982 to the population replacement level which was planned to achieve by 1 988. More than 80% of women aged over 30 or with two children or more are practicing contraception, while the practice rates of women with 0-1 children are 14.0% and 45.1% respectively. The survey has revealed that the increase of contraceptive practice rate during 1982-1985 has mainly attributed to the high acceptance of sterilization procedures which practice rate of the married women has increased from 28.1% to 40.3% for the period. Also, the survey data shows that 24.7% of those women with only one child is practicing contraception for thepurpose of fertility termination. The government, taking into account of rapid changes in contraceptive practice and fertility rates, is formulating a population plan during the sixth fiveyear economic and social development plan (1987-1991) to achieve 1% ofpopulation growth rate by 1993, which was planned to realize by 2000. In order to meet this demographic goal, the existing population control policy measures should be improved to be suited to the recent contraceptive use and fertility changes. From this standpoint, the following considerations should be put forth; 1) improvement of the current program management systems including target allocation and evaluation schems for recruiting new acceptors in the young 20s groups to use contraceptives for birth spacing and to increase high continuation rates through the strengthening of follow-up services for the acceptors, 2) increase of self-supporting contraceptive users by promoting commercial advertisements on contraceptives through mass media including T.V. and radio, 3) development of social support policies including incentive schems, and strengthening of IE & C activities for increasing the proportion of the one-child family, 4) strengthening of population and family planning education in and out school youth, and 5) strengthening of management capabilities at the provincial and local program managers.

  • During the period of 1962 through 1981, a total of 11. 7 million cummulative acceptors have received contraceptive services under the national family planning program. The number of annual acceptors have steadly increased from 151, 200 in 1963 to 842, 200 in 1975, and since then it has maintained the range of 600, 000 to 800, 000 acceptors per year. From the beginning of the program, the IUD had been the principal method of contraception provided by the government program until 1976, at which time the government made female sterilization services available thorough the introduction of the laparoscopy method. The popularity of female sterilization has increased very rapidly during the last few years. Out of 614, 200 program acceptors in 1981, the proportion of female sterilization and IUD acceptors were virtually the same(26.8% and 27.2% respectively). Considering various anticipated problems such as a large proportion of contraceptive users for the fertility termination and the high discontinuation rates of IUD and other traditional method, the government has emphasized the distribution of female sterilization and deemphasized condom and pill contraceptives since 1978. However, the recent service statistics has revealed that the acceptance rate of female sterilization has steadly declined since 1979. Thus, the purpose of this analysis is to review the current government policy on contraceptive distribution with emphasis of female sterilization by estimating the prospect of sterilization acceptablilty. According to the Fifth Five-Year Plan for Family Planning Program(1982-1986) the annual average target of sterilization was set up to secure 230, 000 acceptors by the government sector during the period. If the sterilization target is to be met as planned, about 80 percent of exposed women aged 30-44 will be remained as sterilized women in 1985. This means the the high acceptance rate of sterilization shown in the past years can not be expected, unless the acceptors' age of sterilization is drastically lowered below 30 years. Accordingly, the current policy on contraceptive distribution with emphasis on sterilization should be gradually changed to encourage target population to use contraceptives for birth spacing by increasing access to such contraceptives as IUDs, pills, and condoms, and to improve continuation rates through better program management system including target setting, acceptors' follow-up, supervision, and evaluation system.
