N/A We performed liver needle biopsies on 34 chronic asymptomatic hepatitis B surface antigen (HBsAg) carriers with normal liver function tests. Among them, 12 were found to carry HBeAg and 14 carried anti-HBe. The results were as follows: 1) Of the 34 chronic asymptomatic HBsAg carriers, normal histologies were found in 9, nonspecific reactive changes in 15, chronic persistent hepatitis (CPH) in 9 and chronic active hepatitis (CAH) in l. 2) Of the 12 HBeAg positive carriers, normal histologies were found in 2, nonspecific reactive changes in 6 and CPH in 4 and of the anti-HBe positive carriers, normal histologies were found in 4, nonspecific reactive changes in 6, CPH in 3 and CAH in 1. There was no significant difference between two groups. According to these results, a substantial proportion of chronic asymptomatic HBsAg carriers had histological abnormalities and the status of HBeAg and anti-Hbe did not correlate with liver histology. Qur opinion is liver biopsy is still remains the most useful approach in the evaluation of asymptomatic HBsAg carriers and further long-term clinical studies are needed to understand the prognosis of chronic asymptomatic carrier state.

The effects of soaking time in water on the germination of Lespedeza bicolar seeds used for erosion control were observed respectively; in incubator, at room, and on forestry nursery bed. The results are summarized as follows : 1. The seeds could germinate in any cass at light and dark condition, it is however certified that the Lespedeza bicolar seeds were lihgt demanding seed in its germination. 2. The begining of germination hardly recognized but the germination was hasted by long soaking time in water. 3. In the dark place, the percentage of germination was high acording to the long soaking time, but in the light place it shows the highest percentage in 3 days soaking. 4. The germination energy was the higher the longer soaking time.

The purpose of this study is to develop the reclamation method and suitable species for afforestation on various kinds of stone armoring tips such as mining waste tips, ripped stone tips and weathered debris tips. 10 stone armoring tips and 30 species were estimated. The results of the study are summarized as follows; 1. In common characteristics of stone armoring tips, size of stones and void became larger and soil content became less with an increase in the deposition depth. 2. The most suitable reclamation technique is the pocket planting techique after foundation works like stone terracing. 3. It is necessary to use high water-retaining soil in earth and add organic matters to it. The suitable volume of soil must be determined by characteristics of tips and species planted. And it is essential, in order to retain and accelarate the effect of the earth, to apply the soil fixing treatment with anticorrosive materials. 4. In planting composition, it is available to make the ratio of evergreen trees to shrubs by 1:1 and plant evergreen prostrate shrubs or climbers to 50 percent within shrubs, and alter the order of planting of the same lifeformed species at each terrace. 5. The effective planting method is to plant three sapling or more per pocket in a group. 6. Within estimated species, the more suitable species for afforestation on stone armoring tips are 13 species, and 12 species are also considered good for the same purpose. Especially, 20 species unused before are developed as new plant materials for the environmental conservation.

Pollen grains from 24 species, 7 genera of Korean Oleaceae were investigated about the equat-orial view, aperture type, apeture size, sculpture pattern, exine thickness, pollen size and the other specical features. The results obtaineed were as follows ; 1. A key to the genera on the basis of pollen morphology of Korean Oleaceae was provided. 2. Apeture types of pollen grains were 3-colpate, 3-colporate and 3-colporoidate. 3. Equatorial views of pollen grains were almost speroidal and the other were prolate spher-oidal or subprolate. 4. Sculpture patterns of pollen grains were almost reticulate and Chionanikus retusa was sacbrate. 5. The range of exine thickness of pollen grains was 0.6∼17㎛. 6. The range of pollenlength was 10.5∼25.2㎛. 7. Abeliophyllum destichum Nak. could recongnized the position of already established classification.

This experiments was attempted in order to show the effects of sand gravel contented in water flow on the mean velocity in torrent through the observation of velociiy of orifice discharge from the water tank contented clay. The data obtained are summarized as follows : 1. It is shown that the water flowing velocity was decreased by the increased the ratio of water to clay contented in water tank. 2. As has been shown in Fig. 1 and 2, the mean velocity of wather flowing was greatly decreased when the volume ratio of clay to water was diminished. 3. It semed that the rate of velocity decreased was increased when glasstube length was long. 4. When glass tube diameter was large, the rate of velocity decreased was diminished.

In order to select the superior race of red pine, some characteristics of individual trees of the three natural population selected from Byonsan area (lower inland parts of Byonsan, higher inland parts of Byonsan, seaside outland of Byonsan) were analyzed and compared with already reported superior population (Chuwang-san, An-Myeon-do, Odea-san). The study also investigated the variation of the wood quality of red pine in Byonsan area. The results obtained are summerized as follows; 1. The seed weight in the three natural populations selected from Byonsan area renged from 6.00g to 11.10g. The weight of seeds from the lower inland parts of Byonsan were the heaviest with an average value of 8.64g. 2. According to the classification based on the straightness of the stem, over 70% of all the natural red pine in Byonsan area were classified as A grade. The trees in the lower inland part showed the highest value in A-grade gopulation with a value over 80%. 3. There was no significant statistical differences among three natural red pine populations selected from Byonsan area, in the clear-length, seed length, seed width, seed weight and serration density. 4. As the above results, the natural red pine population of the lower inland parts of Byonsan, among three natural populations were defined by the superior individual trees. 5. The variation of the moisture content at D.B.H. was increased with an annual ring from the pith and the moisture content with height was increased as the measured point became higher. 6. The specific gravity with annual ring at D.B.H. ascended rapidly from pith to the 7th annual ring. From the 8th annual ring to the bark there was no variation. The specific gravity with its height decreased at the measured point became heighter and the average specific gravity based green wood in Bonsan area was 0.9±0.018. 7. The average shrindage of red pine in Byonsan area showed that the tangential direction was 5.62±0.794% the radial direction was 2.98±0.611% and the longitudinal direction was 0.30±0.96%. The ratio of the shirinkage compared with the tangential, radial and the longitudinal direction was 18.7:9.9:1. The tangential dirction shirinkage was shown 1.89 times more than the radial direction shirinkage. We knew it is comprehensible that in each section the shirinkage in the sap wood was larger than the shirinkage of the heart wood and variation of shirindage with height showed a decrease from the butt end to the top in the radial, tangential and longitudinal direction respectively. 8. We suppose that the tracheid length of the early wood at D.B.H. has no differences among the east, west, south and north directions and became longer while along with annual ring from the pith to the 20th annual ring, but there was no variation from the 20th annual ring to the bark. The variation of tracheid length with height showed sharp rising from the butt end to the point of 3.2m, but showed a decrease gradually from the point of 4.2m to the top of the tree. The average tracheid length of the early wood as 3.05±0.251mm.
