        발육단계에 따른 잣나무 자엽내 (子葉內) 수지구의 (樹脂溝) 위치와 수의 변화

        이강영(Kang Young Lee),임경빈(Kyong Bin Yim) 한국산림과학회 1972 한국산림과학회지 Vol.15 No.1

        The variation of numbers of resin canal in cotyledon at different growing stages are observed and results are summarized as follows: 1. Resin canals of cotyledon are not found in May, but in September the average number was 3.26. 2. Unlike in later-formed needles, cotyledon resin canals were external and the range of resin canal numbers are 1 to 5. 3. Correlation coefficients between growing stages and resin canal numbers are significant. And correlations between resin canal numbers and leaf thickness, or the number and cross-section area are also highly significant. 4. Low correlation between resin canal and cotyledon number is observed.

        방위 (方位) 및 수관부위별에 (樹冠部位別) 의한 해송 침엽 수지구수의 (樹脂溝數) 변이

        이강영,임경빈 ( Kang Young Lee,Kyong Bin Yim ) 한국산림과학회 1974 한국산림과학회지 Vol.22 No.1

        Experiments were carried out to find the difference of resin canal numbers by tree age and topophysis of crown of black pine needles, and the results were summarized as follows. 1. The average numbers of resin canal by tree age were increased from the age of 5 years were not difference between 10 and thereafter years significantly. 2. In this observation, the range of resin canal number was 2 to 9. 3. The numbers by the topophysis of crown did not show significant differences but the individual trees showed significant variations in the canal number in younger trees.

        침엽형질상으로 본 한국산 해송집단의 (海松集團) 변이

        이봉수,이강영,임경빈 ( Bong Soo Lee,Kang Young Lee,Kyong Bin Yim ) 한국산림과학회 1984 한국산림과학회지 Vol.63 No.1

        The attempts in this study were made to evaluate the variations in some needle characteristics of Pinus thunbergii between individual trees within population, between populations and between the hypothesized climatic districts. This species occurs naturally along 1:he southern seacoast of Korea penninsula having a relatively mild maritime climate. The followings are the summarized results. The coefficients of variation of the needle volume and needle serration density were generally higher than those of any other traits studied. The significant differences of variations of needle cross section form factor between individual trees within population at 1% level, except only the Young gwang population, were affirmed. In the case of the eastern seacoast district, where the three study populations are included, significances of variation differences were calculated, 5%r level at needle serration density and cross section area and 1% Level at needle volume. The very high significant difference of the variations of needle cross section form factor and needle longitudinal form factor were shown between population of the western seacoast district and 5% Level significance at needle volume in the southern seacoast district. The high significant differences between districts in respect to needle cross section form factor and cross section area were calculated. The Duncan`s multiple range test showed the dissimilarity of the said characteristics between the hypothesized climatic districts. Summing up the results obtained so far, individual tree and population variations were markedly noted statistically and these may be extended to the silvicultural technology.

        Purpose : To evaluate the impact of added progestogen on biochemical markers of the bone turnover undergoing hormone replacement therapy in the postmenopausal women. Materials and Methods : There are 71 postmentopausal women who are divided into three groups (Group I, Group II, Group III). Group I(continuous combined)is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 2.5mg, day 1-30), Group II(unopposed estrogen) is given conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 5mg, day 1-12). And there were measured serum osteocalcin, serum total alkaline phosphatase and urinary deoxypyridinoline excretion before starting hormone replacement therapy and 12 months later. Results : The serum osteocalcin, serum total alkaline phosphatase and urinary deoxypyridinoline excretion significantly decreased after hormone replacement therapy (Group, I, II, III). And there was no significance in decreases in biochemical markers of the bone turnover among three groups. Conclusions : It was concluded that the impact of added progestogen on the biochemical markers of the bone turnover undergoing hormone replaced therapy in postmenopausal women was not significant than nothing added group. Thus we concluded that progestogen was not impact on decreasing on the biochemical markers of the bone turnover in postmenopausal women undergoing hormone replacement therapy.
