The Geumganasa Temple site two Ridege-end tiles at the Buyeo National Museum(The Buyeo2150-1 and 2150-2, hereinafter referred to as 2150-1 and 2150-2) were excavated the Geumgangsa Temple site. They provide important materials for investigating the shapes and production techniques of the ridge-end tiles of the time since their lower portions remain relatively intact. This study is intended to examine whether the two ridge-end tiles were identical. Conservation treatment, including removal of foreign substances, was conducted in preparation for observation with the naked eye to compare the formal features and production techniques of the two examples. The study revealed that these ridge-end tiles shared formal features such as surface color, clay composition, shape, size, and decoration; however, they differed in terms of production technique. The 2150-1 tile was made by assembling a separately-made body and wing and has no hole through the back, while the 2150-2 tile had its body and wing made as a single unit using long clay plates and features circular holes in the back. It was revealed that one portion of the body of both tiles was intentionally tilted during the production process.

Olive flounder (Paralichthys olivaceus) is the major mariculture fish in Korea. The annual aquaculture production of olive flounder in Korea during the period of 2003 was 300,000 ton (2002 Statistics, Ministry of Maritime Affairs & Fisheries, Korea Government). Anesthetics is very necessary in aquaculture to minimize stress and damage during harvesting, grading, transportation, spawning induction and handling to fish. In the present study, isoeugenol as new anesthetic in marine fish, especially olive flounder, was examined to know the efficacy and proper concentration. As a result, olive flounder adult was exhibited sedation at 5 ppm at 10 and $15^{\circ}C$, and 7.5 ppm at $20^{\circ}C$, respectively. Anesthesia was required at least 10, 7.5 and 10 ppm at $10^{\circ}C$, $15^{\circ}C$ and at $20^{\circ}C$, respectively. In case of fry, the effect of sedation was observed from 2.5 ppm at $10^{\circ}C$ and 5 ppm at 15 and $20^{\circ}C$, respectively. Anesthesia was observed from 2.5 ppm at $10^{\circ}C$, 5 ppm at 15 and $20^{\circ}C$, respectively. In acute toxicity test, it was impossible to explore $LD_{50}$ with the concentration of isoeugenol adult at $15^{\circ}C$ used, but over immersion volume of 15 ppm at $15^{\circ}C$ was observed mortality in fry. Based on the present study, isoeugenol was identified as a safe and active anesthetic to olive flounder.

In this study, the correlations of concentrations in sediment heavy metals between two pretreatment methods, total digestion and aqua regia digestion, have been investigated. Total 43 samples had been collected from streams and lakes in Yeongsan and Seomjin watersheds. They were decomposed in two pretreatment methods and five metal components (Cd, Cr, Ni, Pb, Zn) were analyzed. Overall average concentrations of heavy metals were Zn>Cr>Pb>Ni>Cd in the order. The concentrations of aqua regia digestion were 35.0% (Cd), 53.8% (Cr), 66.2% (Ni), 64.4% (Pb) and 76.4% (Zn) of the concentrations of total digestion and heavy metal concentrations of total digestion were higher. Heavy metal concentrations in sediments from lakes were higher than those from streams. The correlation equations between the concentrations of total digestion and aqua regia digestion were obtained. The concentrations of Zn and Ni, which showed strong linear correlations, increased in aqua regia digestion as the concentration in total digestion increased. The linear correlation coefficients between two digestion methods for most analyzed metals were above the average correlation. However, these results can be applied with limitations due to heterogeneity of sediments.

Purpose: To evaluate the effectiveness of pilot program on standard curriculum of hospice palliative care education; a basic training program for physician, nurse, social worker and clergies at hospice institute. Methods: To develop an educational program, we used the Education in Palliative and End-of-life Care (EPEC) program as a paradigm and modified it to be suited in our situation: The standard curriculum consists of 19 modules, and it is designed to be applied to the teaching methods, including lecture, interactive lecture, small group discussions, and role play. To verify its contents and teaching methods, we implemented a pilot program which consisted of 3 modules, using various teaching methods; trigger video tapes, interactive lecture, small group discussions, and role play. Results: Overwhelming majority were satisfied with the teaching methods and learner-centered methods, and agreed that the contents were clinically relevant to the care of dying patients. They also indicated that their attitudes would likely change as a result of the education. Conclusion: The effects of the pilot program on standard curriculum of hospice and palliative care are very positive and has broader implications for improving hospice palliative care education. For successful implementation of the program, trainers must also be prepared to teach effectively. Also it must be accompanied with train-the trainer program.

Purpose: The present study is aimed to evaluate the combined effect of recombinant human bone morphogenetic protein 2 (rhBMP-2) and recombinant human vascular endothelial growth factor (rhVEGF) coated onto anodized implants on osseointeration. Materials and methods: Six New Zealand white rabbit were used in this study. Each animal received 4 implants that were either coated with rhBMP-2 and rhVEGF (Study group) or anodized implant (Control group) in both tibia. This was performed using a randomized split-mouth design. A total 24 implants were used. The implant stability quotient (ISQ) value using resonance frequency analyser and removal torque (RTQ) measurement were investigated at 2 and 8 weeks. The t-test was used for statistical analysis (${\alpha}$=.05). Results: Control and study group showed good osseointegration at 8 weeks. The ISQ and RTQ values of study group were significant compared with the control group at 8 weeks (P<.05). However, No statistical significance was observed at 2 weeks (P>.05). Conclusion: It was concluded that rhBMP-2 with rhVEGF coated onto anodized implants can induce better osseointegration at late healing period.

We discovered following on our surveys to the island six times in May, August (1978), in April, May, June, July (1979). There are 73 families, 158 genera, 189 species, 31 varieties over Tracheophyta Fuller & Tippo. Till early or middle age of Lee Dynasty, the island's dominant plants was evergreen broad-leaved trees, mainly consisted with Camellia japonica L. and Castanopsis cuspidata Schot, var. sieboldii Nakai but due to the population growth and increased exiles constant ground burnt off fr cultivation, the number of evergreen broad-leaved trees was decreased and that of P. densiflora S. et Z. replaced position. That is to say, the island was dominated by the flora of the subtropical zone era, but it has been complicated by flora of the temperate zone whose reproductivity is more vivid, in modern era. Recently Pinus thunbergiana Franco, Robinia pseudo-acasasia L. Amoroha fructicasia L. invaded and reserved inthe island. During a decade of the end of Japanes rule and after liberation about all of Pinus densiflora S. et Z. were cut downed, and after that, under the Forest Bureau, there have being sucessed to Pinus thunbergiana France. Camellia japonica L. other 20 species of evergreen broad-leaved trees are distributed in Island Wi, a tutelary shrine of Dae Ri, a mountain at the back of a village of Chi Do Ri and a mountain at the back of Jin Ri administrative office of a township. The special plants of the island are 1) state of Lycoris aurea Herb which of foun in a ridge between fields and forest around Jin Ri and 2) stock of Cmbidium virescens Lindly bloomed under the Pinus densiflora forest of Keun Tan Chi Do.

With construction industry recession, many construction companies are increasingly conducting the development projects by themselves. However, housing projects requested by developers still stand large portion. Although many studies on feasibility analysis were released, they mainly focused on economic feasibility and lacked research on factors and criterions of overall project. Also, because previous studies overly break downed factors related to project, they rarely used in practice. Therefore, this study developed the feasibility analysis model of housing development projects to help main contractors to easily and effectively decide if it is feasible enough to promote the projects requested by developers, and verified the reliability of the model. In this study, thirty one driving factors were identified under seven different categories and the criterion of each factor was also developed. The survey on important index of each factor found "salability", "economic feasibility", "site location" and "method of raising fund" significant. 3 projects were tested by the model and its results showed resonable reliability.

In this study, the effects of intake of Acer mono Max. seed oil, and Magnolia denudata seed oil on the lipid levels of mouse blood were compared to those of commercially available vegetable oils. Five ICR mice were each fed a corn oil, Acer mono Max. seed oil, and Magnolia denudata seed oil supplemented diet for a total of 8 weeks. The serum profiles of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were high in palmitic acid, oleic acid, and linoleic acid. The saturated fatty acid contents of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were 3.95% and 0.88%, whereas the unsaturated fatty acid contents were 8.71% and 4.60%, respectively. The liver and spleen weights of mice fed Acer mono Max. seed oil were higher than those fed corn oil (p<0.05). Total cholesterol level was highest in mice fed Acer mono Max. seed oil (p<0.05), whereas there were no significant changes in the cholesterol levels of mice fed Magnolia denudata seed oil and corn oil. The HDL-cholesterol levels in mice fed Acer mono Max. seed oil ($175.80{\pm}27.66mg/d{\ell}$) and in those fed Magnolia denudata seed oil ($145.20{\pm}19.10mg/d{\ell}$) were higher compared to those of mice fed corn oil (p<0.05). In conclusion, there were no significant differences in fatty acid composition between mice fed Acer mono Max. seed oil and Magnolia denudata seed oil. Future study on the antioxidant effects of seed oils should be carried out.
