Cheon­Dong valley forest, bearing a cool­temperature, broadleaf­deciduous forest zone, ranging from 500m to 1200m by elevation in Mt. Sobeak National Park area was investigated for forest vegetation structure research. Ten plots of 1000㎡ size set up by the clumped sampling method and Classification and Polar Ordination were applied for vegetation structure analysis by environmental gradient the flora of the vascular plants collected from this investigated area were 32 families, 35 genera, 42 species and 3 varieties. Ranging from 500m to 1200m to elevation, Number of species, Number of individuals and Species diversity showed their highest values at 900m elevation respectively. And with increasing altitude those all values showed a tendency decreasing gradually. According to the Importance Value the leading dominant tree species in canopy layer were Styrax obassia, Quercus variabilis, Q. aliena, Carpinus codata while Lindera obtusiloba, Lespedeza bicolor were in understory at low elevation, ranging from 500m to 900m. Ant at high elevation area, ranging from 900m to 1200m, the leading dominant species were Q. monglica, Q. acutisima, Betula platyphylla var. japonica, Cornus controversa, Acer pseudo­sieboldianum, Fraxinus mandshurica, n canopy layer while Deuzia paviflora, Pinus laxiflora were in understory. The result from Classification and Polar Ordination analysis, they showed similarity that the forest vegetation of Sobeak valley area was classified into two sub­communities, one is Q. mongolica, Styrux obassia―Styrux obassia, Q. aliena, Carpinus codata―Styrux obassia, Lespedeza bicolor community and the other is Q. variabilia, Q. acutisima―Acer mono, Fruxinus rhynchophylla―Deutzia parviflora, Lindera obtusiloba community and the major environmental factors were considered to be the difference of altitude and the conditions of soil pH. The successional trends of tree species will be from Q. variabilis, Q. acutisima through Acer pseudo­sieboldianum, Fraxinus rhynchophylla to Carpinus codata at high elevation area, ranging from 900m to 1200m, and from Q. mongolica, Styrax obassia through Styrax obassia, Q aliena to Carpinus codata at low elevation area, ranging from 500m to 900m.

This study compared and analyzed the effect of income-redistribution, calculating the occupied rate of insurance contribution, the occupied rate of insurance benefits, the rate of insurance benefits. income-transfer rate, decile distribution ratio, concentration index and Gini-coefficient by classes of insurance contribution, collecting data on the basis of the estimated details of insurance contribution and individual money wage lists for each one year before and after the combination of medical insurance program for industrial workers, by systematic sampling, extracting 4,160 families(14,764 people) among people applied to medical insurance program for self employees in Taegu Metropolitan City on the basis of Oct. 1st in 1998 with 227 associations of medical insurance program for self employees and medical insurance program for government employees and private school teachers combined, comparing the effect of income redistribution of before and after the combination of medical insurance program for self employees. The insurance contribution by household after the combination of medical insurance program for self employees showed the increase rate of average 20.9%, among them households of 68.8% increased and 31.2% decreased. The increase rate of insurance contribution over 15% from the 6th degree to the 10th degree showed, while 3.9% decreased in the 1st degree. The occupied rate of insurance contribution on classes by decile increased from lower classes by decile towards upper ones, and the occupied rate increased more from 8th degree to 10th degree after the combination than before the one, but the rest of all from 1st degree to 7th degree decreased. The effect of income-redistribution was more positive because the degree of inequality was more deepened from 0.64 of the before-combination to 0.45 of the after-one in decile distribution ratio, from 0.26 to 0.34 in Gini-coefficient. On the basis of Oct. 1st in 1998 that 227 associations of medical insurance program for self employees was combined into one, we could say that the equality of imposing medical insurance contribution was more re-considered in the after-combination than in the before-one. The study of the effect of income-redistribution should continuously be accomplished that can grasp the equality about the imposing system of insurance contribution, under the system of combined medical insurance towards enforcement of the law of national health insurance, because the purpose is the building up the system of single insurance contribution on the basis of whole nation income.

The purpose of this study os to investigate the formation of calcium phosphate on Ti-6Al-4V surface on aqueous solutions containing phosphate and calcium ions. The surface of Ti-6Al-4V specimens were treated in phosphate buffered solutions for 3 days followed by immersion in calcium phosphate buffered solutions for 10 days. These solutions have different concentration and pH(pH 5.8, 7.0, 8.0) one another. Then, the specimens treated with P and Ca ions and control group without surface treatment were immersed in Hanks' balanced solution for 30 days to make sure the effectiveness of this surface treatment. All specimens were characterized using scanning electron microscopy(SEM), X-ray diffractometry(XRD) and Fourier transform infrared spectrophotometry(FT-IR). The amount of crystallized particles formed on the specimens by surface treatment was significantly increased in all experimental conditions as compared with that immersed only in Hanks' solution. Dense granular shaped precipitates were observed on the surface and these particles were recognized as calcium phosphate similar to HA(hydroxyapatite) or TCP(tri-calcium phosphate).

This study compared and analyzed the effect of income-redistribution, calculating the occupied rate of insurance contribution, the occupied rate of insurance benefits, the rate of insurance benefits, income-transfer rate, decile distribution ratio, concentration index and Gini-coefficient by classes of insurance contribution, collecting data on the basis of the estimated details of insurance contribution and individual money wage lists for each one year before and after the combination of medical insurance program for industrial workers, by systematic sampling, extracting each 497 families(taxable income grades and appraised income grades) among people applied to medical insurance program for self employees in Taegu Metropolitan City on the basis of Oct. 1st in 1998. As the result, on the basis of the rate of insurance contribution, the rate of insurance benefits and the rate of medical insurance benefits(insurance benefits/ insurance contribution), we could say that the equality of imposing medical insurance contribution was more re-considered in the taxable income grades than in the appraised income grades. But this study analyzed with classes divided, anyway, on the basis of insurance contribution, we have limit in explaining the correct effect of income-redistribution, because it was not analyzed according to classes of income, though it helps to analogize the effect of income-redistribution. So there must be analysis about the effect of income-redistribution, on the basis of the system, building up the system to grasp the correct income of the insureds of medical insurance program for self employees. The study of the effect of income-redistribution should continuously be accomplished that can grasp the equality about the imposing system of insurance contribution, under the system of combined medical insurance towards enforcement of the law of national health insurance, because the purpose is the building up the system of single insurance contribution on the basis of whole nation income.

The primary medical care is the most important part in the Medical Delivery System. So this study was to survey the average of treatment amount among the kind of specialty through the medical insurance claims concerning 963 clinics during the period of one year, 1997, in Taegu. The average revenue of medical treatment amount was 187,950,000won, the average case of medical treatment amount was 9,255cases and the charges per case was 21,596won. The result of survey about the internists, general surgeons, family physicians, general practitioners and pediatricians was as follows : Upon the treatment cases, significant variables of the internists were the number of practitioners of clinic, employed numbers and the number of equipments. Significant variables of the general surgeons were the age of practitioners, the opening year, the number of practitioners, employed numbers and the number of beds. Significant variables of the family physicians were the age of practitioners, the opening year and the number of equipments. Significant variables of the general practitioners were the number of practitioners of clinic and number of beds. Significant variables of pediatricians were the number of practitioners and employed numbers. In view of the tendency for the park of medical insurance to enlarge more and more in revenue of the whole treatment amount, and through the analysis of factors influencing upon treatment amount of medical insurance, we will anticipate the expenditure of treatment amount of insurance and need to establish efficient medical insurance policy to reduce the differences between the distributions of treatment amount of insurance among special departments. Therefore the health manpower policy about the private medical practitioners will be continuously study.
