In this paper, setting and strength development of cement mortar are discussed under various mineral admixture content and curing temperature. Setting time exhibited an increasing tendency with an increase in curing temperature. Under low curing temperature, use of CKD resulted in a reduction in setting retarding, whereas FA and BS retarded the setting time of cement mortar. For compressive strength, high curing temperature and age leaded to an increase in compressive strength of concrete. Under low curing temperature, the use of CKD resulted in an enhancement of compressive strength at early stage, and exhibited a similar level of compressive strength with plain concrete. For this reason, use of CKD in cold weather concreting has positive effect on strength development at low curing temperature under early age.

The objective the paper is to investigate the physical and mechanical properties of concrete incorporating mineral admixtures. For setting properties, at low curing temperature, setting time of concrete with mineral admixture is delayed compared with that of plain concrete. But, use of cement kiln dust(CKD) has a desirable effect on reducing setting retard under low curing temperature. For compressive strength, concrete with FA and BS have low strength at early stage compared with that of plain concrete under low curing temperature. However, the use of CKD resulted in an enhancement of compressive strength at early stage under low curing temperature, and exhibited a similar level of compressive strength with plain concrete. For this reason, use of CKD in cold weather concreting has positive effect on strength development at low curing temperature under early age.

Purpose : The purpose of this study is to examine the effects of trunk stability training on improving trunk control, respiratory function, and respiratory muscle activation in stroke patients. Methods : The subjects were assigned to two groups: the intervention group (n=15) and the control group (n=15). Both groups participated in a conventional stroke rehabilitation program, but the intervention group also received trunk stability training for 30 minutes a day, 3 times a week, for 6 weeks. The main trunk stability exercise consisted of the dead bug exercise. Trunk control was assessed using a trunk impairment scale, and respiratory function (pulmonary function and respiratory muscle function) was assessed using spirometry. The data were analyzed using the Pearson correlation, independent t-test, and paired t-test. Results : Trunk control was significantly positively correlated with pulmonary function and respiratory muscle strength. Both groups showed a significant increase in trunk control and respiratory function. Conclusion : This study demonstrated that a conventional stroke rehabilitation program and trunk stability training have positive effects on respiratory function and respiratory muscle activation in stroke patients.

郭秀年,徐明基 목포대학교 자연자원개발연구소 2000 자연자원연구 Vol.3 No.-

The possibility of AgNO3 and ethrel(2-chorophosphonic acid)treatments to regulate sex expression of Cucurbita for hybrid seed production was investigated. Treatments of Cucurbita plants with ethrel induced an earlier female flowers and greater production of female flowers, while those with AgNO3 induced a greater production of male flowers and late female flowers. Treatment with high concentration of ethrel reduced the growth but that with AgNO3 showed little effects of the growth. The effects of AgNO3 and ethrel on sex expression in Cucurbita varied among the species and cultivars. It seems due to the difference in the femaleness of species and cultivars investigated.

The purpose of this study was to investigate the effect of multi-functional fabric on EEG and growth hormone (GH) during sleep and quality of sleep with the 9 young female athletes. The subjects participated in separated experimental procedure; sleeping in multi-functional fabric wear (experimental group) and cotton wear (control group) for 450min. During the night (22:00-05:30), we recorded the changes of nocturnal polysomnographic sleep recording and GH were measured every 60min. The results show that there are significant differences in percentage of stage 1, 2 and slow wave sleep (SWS) between two groups(S1, p<.05;S2, SWS, p<.01). The SWS percentage of experimental group is 1.89 times higher than control group. The changes of GH secretion varied depending on two experimental procedures. The peak of GH secretion in experimental group is more than controls by 2.4time (p<.001). The quality of sleep in experimetal group is significantly higher than control (p<.01). These results suggest muti-functional fabric wear is effective in inducing the deep sleep and increasing GH and quality of sleep.

This study was conducted for the purpose of evaluating coverage of small companies with less than 5 persons by Corporate Insurance since July 2001 and of suggesting policy implication. This coverage expansion by Corporate Insurance was intended for improving equity level of contribution imposition, alleviating financial burden of employees and achieving financial stability of health insurance. While, from July 2001 to December, the number of newly covered beneficiaries was about 642 thousand persons, the number of Regional beneficiaries before the new coverage expansion by Corporate Insurance was 533 thousand persons. And the number of Corporate Insurance beneficiaries before the coverage expansion was 101 thousand persons. For the same period, the number of companies by the new coverage expansion of Corporate Insurance was 88,751. Before and after the expansion, taking into account changes of individual contribution levels, payment share levels of contribution were reduced to the 77.6% of the beneficiaries newly covered by Corporate Insurance. Instead, payment share level of contribution of employers was increased more than before. And 19,530 million won was increased in National Health Insurance Expenditure. 7,331million won was increased in Corporate Insurance revenue. Expenditure reduction effect of 12,199 million won was able to be obtained in Regional Insurance. In order to implement successfully the coverage expansion by Corporate Insurance in times ahead, employers' contribution share should be reduced, when considering low profitability levels of small companies.
