SA508 Gr.4N Ni-Cr-Mo low alloy steel, in which Ni and Cr contents are higher than in commercial SA508 Gr.3 Mn-Mo-Ni low alloy steels, may be a candidate reactor pressure vessel (RPV) material with higher strength and toughness from its tempered martensitic microstructure. The inner surface of the RPV is weld-cladded with stainless steels to prevent corrosion. The goal of this study is to evaluate the microstructural properties of the clad interface between Ni-Cr-Mo low alloy steel and stainless weldment, and the effects of post weld heat treatment (PWHT) on the properties. The properties of the clad interface were compared with those of commercial Mn-Mo-Ni low alloy steel. Multi-layer welding of model alloys with ER308L and ER309L stainless steel by the SAW method was performed, and then PWHT was conducted at 610℃ for 30 h. The microstructural changes of the clad interface were analyzed using OM, SEM and TEM, and micro-Vickers hardness tests were performed. Before PWHT, the heat affected zone (HAZ) showed higher hardness than base and weld metals due to formation of martensite after welding in both steels. In addition, the hardness of the HAZ in Ni-Cr-Mo low alloy steel was higher than that in Mn-Mo-Ni low alloy steel due to a comparatively high martensite fraction. The hardness of the HAZ decreased after PWHT in both steels, but the dark region was formed near the fusion line in which the hardness was locally high. In the case of Mn-Mo-Ni low alloy steel, formation of fine Cr-carbides in the weld region near the fusion line by diffusion of C from the base metal resulted in locally high hardness in the dark region. However, the precipitates of the region in the Ni-Cr-Mo low alloy steel were similar to that in the base metal, and the hardness in the region was not greatly different from that in the base metal.

1. The study was conducted on the optimum condition of the treated substrate with dilute sulphuric acid solution and cellulase for saccharification. The wood (saw dust) of Alnus hirsuta Rupr. (10∼15 years) was treated with 0.3%, 0.6%, 0.9%, 1.2%, 1.5%, H₂SO₄ solution at 1.5㎏/㎠ for 15min., 30min., 45min., and 60min., followed by thermal treatment at 190℃ for 30min., and screening with 60 mesh sieve, after which to 0.5 grams of each sample was added 0.5㎖ cellulase solution, and 50㎖ 0.1M acetic acid buffer solution (pH 5.0), after incubating at 40℃ for 96hr. 2. The crude cellulase of Trichoderma viride Perx. ex. Fr. SANK 16374 was produced by the submerged culture process and produced in the culture fluid was salted out quantitatively by the use of ammonium sulfite. 3. Reducing sugar was determined by the 3.5-dinitrosalicylic acid (DNS) method. 4. The reducing sugar was increased with increase of the sulphuric acid concentration and saw dust was treated with 1.5% H₂SO₄ solution at 1.5㎏/㎠ for 45min. showed the best saccharification (16.0%). The reducing sugar formation did not show statistically significant in 5% levels by thermal treatment time 45min. and 60min. 5. The substrate for cellulase which was treated with 0.9% H₂SO₄ solution at 1.5㎏/㎠ for 60min. showed the best reducing sugar formation (23.6%). And did not show significant difference in 5% levels at 0.9%, 1.2%, and 1.5% H₂SO₄ solution.

Cyanex 572에 의한 경희토류 다성분 혼합 용액에서 La, Ce, Pr, Nd, Sm의 분리특성에 대해 연구하였다. 5성분계 혼합 용액에서 추출제 농도가 증가할수록 5성분 모두 $pH_{50}$(추출율이 50%인 pH) 값은 감소하였다. 추출제 농도 0.6 M 이상에서 La과 Ce, Nd와 Sm 는 10 이상의 분리계수 값을 보인 반면, Ce과 Pr, Pr과 Nd 사이의 분리계수는 0.5~2.2로 낮았다. 분리계수 개선을 위해 0.6 M Cyanex 572에 TBP를 첨가하였으나 상 분리 속도나 분리계수 개선 효과는 나타나지 않았다. 실험 결과를 고찰한 결과, La/(Pr, Nd, Sm) 그룹과 (Pr, Nd)/Sm 의 경우는 그룹 별 분리는 가능할 것으로 보이나, (La, Ce) 과 (Pr, Nd)의 그룹분리는 Ce와 Pr 사이의 분리계수가 낮아 어려울 것으로 사료된다. Extraction and separation behaviors of La, Ce, Pr, Nd and Sm from light rare earth multi - component mixed solutions by Cyanex 572 were studied. As extractant concentration increased, the $pH_{50}$ values of all the five components decreased. When extractant concentration was larger than 0.6 M, the separation factor of La and Ce, Nd and Sm was higher than 10, while the separation factor between Ce and Pr, Pr and Nd was as low as 0.5~2.2. Addition of TBP to the 0.6 M Cyanex 572 had little synergistic effect on the phase separation rate and separation factor. From the analysis of experiment results, group separation of [La]/[Pr, Nd, Sm] and [Pr, Nd]/[Sm] could be possible, but in case of the group separation between [La, Ce] and [Pr, Nd] was not available because of the low separation factor between Ce and Pr.

Liriodendron tulipifera L. has been well adapted to the Korean climate since it was first introduced from the U.S.A. in the 1960`s. Recently, Korea Forest Service decided to disseminate L. tulipifera as an afforestation tree species. However, there have been no guidelines developed for seedling production of L. tulipifera in Korea. According1y, this study was conducted to develop the optimal conditions for the seedling production of L. tulipifera. For this purpose, Seeds were collected from a 40-year-old single tree planted in the garden of the Dept. of Forest Genetic Resources, Korea Forest Research Institute. Germination percentage was examined at different nursery conditions (i .e. green house, irrigation nursery, and field nursery) and with different seed covering materials (i.e. sawdust, soil, and sand). The optimal quantity of sowed seeds and optimal number of planting trees per m^2 were examined for the sake of the production of standard seedlings. Finally, the optimal time of root pruning was investigated in order to improve survival rate and to promote early growth after afforestation. The highest germination percentage (92.6%) was observed in the seeds covered with sawdust in the green house, while the lowest germination percentage (10.8%) was investigated in the seeds covered with sand in the field nursery. The optimal quantity of sowed seeds fumed out to be 50g/m^2 in the irrigation nursery and 150g/m^2 in the field nursery. Thirty five of standard seedlings were produced when 50 seedlings were Planted per m^2. The optimal time of root pruning appeared to be the beginning of August. The T/R ratio of root-pruned seedlings was 45% , which was lower than that of root-pruned seedlings, and hairy roots were more developed in the root-pruned seedlings than in the root-unpruned ones.

The provenance test was performed using seeds from six provenances of eastern white pine(Pinus strobus L.) originated from USA. The main purpose of this study was to determine the best seed source of P. strobus which shows the best growth in Korea and has the most beautiful tree-form. Seed quality, growth performance in a seed bed and field, and needle characteristics of each provenance were investigated to distribute the seeds after separating seed provenances for wood producing and landscaping. There were a lot of variations in the number of seeds per gram and per litter and the average weight of 1,000 seeds among provenances. In the height growth of four-year-old trees, Georgia and North Carolina provenances which were heavy in seed weight showed better results than other provenances. The height growth of P. strobus started later than that of Pinus koraiensis Sieb. et Zucc., but the volume growth of the trees of P. strobus started earlier than that of P. koraiensis. In the volume growth of 16-year-old trees, Georgia(71% higher than average value) and North Carolina(61% higher than average value) provenances showed the best growth while Minnesota provenances showed the poorest growth(60% less than average value). Georgia and North Carolina provenances were considered to be appropriate seed provenances for wood producing because of the good tree growth, and New York provenance was considered to be the best seed provenance for landscaping purpose because of the good tree form.
