This study not only carried out to grasp about the summarized characteristics of the relationship between international timber market and production trend of wood products, but also focused on the analysis of korean wood demand and the long-term forecast with econometric analysis. The result of regression analysis for wood demand in Korea is that coniferous roundwood demand(CIWD) is explained by coniferous foreign roundwood price(CWRI), Gross domestic product(GDP), a dummy variable. Non-coniferous roundwood demand(NCIWD)is explained by non-coniferous roundwood price(NCWRI), coniferous roundwood price(CWRI), a dummy variable. As the result of long-term forecast by base case, the total roundwood demand was forecasted 11,107,000㎥ in the year 2000, 11,781,000㎥ in 2005, 12,565,000㎥ in 2010. As the result of scenario 1, total roundwood demand was forecasted 11,027,000㎥ in 2000, 11,435,000㎥ in 2005, 11,952,000㎥ in 2010. And as the result by scenario 2, total roundwood demand was forecasted 11,341,000㎥ in 2000, 12,208,000㎥ in 2005 13,257,000㎥ in 2010.

In addition to the development of functional cosmetics, technology to increase percutaneous absorption rate when applied to the skin is an important task. In this experiment, oleic acid was used as a skin absorption promoter, and its effect on transdermal permeability of adenosine was studied and analyzed using a skin-like membrane. As a result of the experiment, it was investigated that the permeability coefficient and concentration of adenosine are proportional to the content of oleic acid. This indicates that a high proportion of oleic acid is effective as a skin absorption promoter.

The plasma parameters such as temperature and plasma potential was found by the use of a Langmuir probe. It is well known that the properties of the laser-produced plasma plume have an effection those of thin films. Thus, to understand the deposition processes of thin films and to deposit thin films having specific properties it is to necessary to probe the plasma, so we used Langmuir probe. The second harmonic of a Q-switched Nd:YAG laser have 6ns pulse-width and the peak intensity of focused laser beam on the high purity(99.7%) graphite target was nearly ??.

This experiment was carried out to determine the effectiveness and productivity of feed grade animal fats(FGAF) supplemented high energy ration as compared to prevailing Korean swine ration. The items checked included 1) daily gain, 2) feed intake and its efficiency, and carcass characteristics. Fifty four heads of barrow and gilt Yorkshire, Landrace and Hampshire were alloted to three groups: control (no FGAF added), 2% lot (2% FGAF added) and 4%(4%FGAF added). This trial lasted for 100 days, covering both growing and finishing periods in the National Livestock Breeding Station. The results of feeding trial and carcass evaluation are recorded in tables 4 to 12. The following is a summary of the results obtained. a) There were no signigicant gain in body weight during growing period, but highly significant differences among groups, sexes, and breeds during overall period. (P<0.01) b) In daily gain there were highly significant differences among the groups during the finishing and overall periods (p<0.01) and the Yorkshire breed showed a significant difference in the finishing period (p<0.05) and a highly significant difference during the overall period (P<0.01). Barrows showed highly significant differences during the finishing and overall periods (P<0.01). c) Feed intake was not significantly affected among groups, but the Yorkshire breed took more feed. Feed efficiency was better in 4% group than other groups (P<0.05). d) The days to reach market weight was no differences significant among groups, but barrow were better than gilt (p<0.01). e) The carcass evaluation was conducted on only twenty seven barrow. There were, generally, no significant differences among groups, except Hanpshire being better in dressing percentages (P<0.05). low in backfat thickness (P<0.01). f) Prices for feed and pork are very unstable in Korea. What is profitable at one time may not be five month or even several weeks late. Because the pork price and feedstuff situation in Korea are so unpredicable, this report mainly presents performance and carcass evaluation data, which can later be use for economic evaluations of the use of FGAF showing only case study in Korean hog ration.

Two quadruplex PCR reactions were designed for 7 tetrameric (D3S2406, D4S2368, D5S818, D7S821, D9S925, D13S317, D19S253) and one trimeric (D6S1043) short tandem repeats loci to study the allele frequency and the applicability of genetic variation in these loci in forensic case works. For 310 unrelated Koreans DNA was isolated from peripheral blood using phenol/chloroform method. Quadruplex I was consisted of D4S2368, D6S1043, D7S821, D9S925 and quadruplex II D3S2406, D5S818, D13S317, D19S253. The amplified products were analyzed by 5% polyacrylamide gel electrophoresis followed by silver staining. The heterozygosity in each loci ranged 92.91-66.13%, and PD(Power of Discrimination) was above 085 in each loci. Every loci except D6S1043 followed hardy-Weinberg expectation. The cumulative PI was low as 1.65×10-10. Two mutations were noted, one in D19S253 and the other in D9S925 among 234 gametes. With these results above eight STR loci studied here preyed to be highly polymorphic enough to be used in forensic field. This study provides valuable population data in these loci for Korean.

Thin amorphous carbon films were deposited by a Q-switched Nd;YAG 532nm with beam power density of ?? on the high purity graphite (99.7%). The pressure of vacuum chamber was ?? Torr. In order to estimate the quality of the Pulsed Laser Deposition films one of the most important optical properties, bandgap energy, was characterized by transmission and reflection in the range of the visible, and an optical direct bandgap energy of 2.45eV and indirect bandgap energy 0.36eV were obtained. Surface morphology of amorphous film was investigated by AFM (Atomic Force Microscopy). Its surface roughness is 70nm. Comparing our results with the published values in the literature we have confidence that our films show the good quality for optical properties.

In this dissertation, we have studied on the fabrication of Sr ferrite plastic magnet with additional Nd. First, we selected SrO5.9F₂O₃of nonstoichimatric composition as the basic composition of specimen ferrite since its magnetic property was excellent. Then, we added Nd to the specimen. In order to control the properties of the particles on fabrication of magnetic powder, 0.3wt% CaCO₃, 0.2wt% SiO₂, 0.twt% Al₂O₃and 0.5wt% Na₂SiO₃were added. For carbon coating ont he compound specimen, 5wt% polyvinylalchohol was added and then the compound specimen was calcinated under N₂environment at 1,225 ℃. After performaing grinding process for 18 hours, we obtained 1.0~1.2㎛ size of single domain magnetic powder. We added 1 wt% silane coupling and 1 wt% calcium stearate to the Sr ferrite powder with additional Nd, and then mixed them well. Next, we pelleted them after kneading them, using polyamide12 as a binder. The pelleted specimen was injection-moulded using anisotropic mould under magnetic field of 12kOe. As the results of property tests for the fabricated specimen magnet, we find that the fabricated magnet has the following excellent peroperties at Nd 12.5wt%: bHc=2.84kOe, Br=3.23kG and (BH)max=2.49MGOe.
