This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

Greenhouse industry has been growing in many countries due to both the advantage of stable year-round crop production and increased demand for fresh vegetables. In greenhouse cultivation, $CO_2$ concentration plays an essential role in the photosynthesis process of crops. Continuous and accurate monitoring of $CO_2$ level in the greenhouse would improve profitability and reduce environmental impact, through optimum control of greenhouse $CO_2$ enrichment and efficient crop production, as compared with the conventional management practices without monitoring and control of $CO_2$ level. In this study, a mathematical model was developed to estimate the $CO_2$ emission from soil as affected by environmental factors in greenhouses. Among various model types evaluated, a linear regression model provided the best coefficient of determination. Selected predictor variables were solar radiation and relative humidity and exponential transformation of both. As a response variable in the model, the difference between $CO_2$ concentrations at the soil surface and 5-cm depth showed are latively strong relationship with the predictor variables. Segmented regression analysis showed that better models were obtained when the entire daily dataset was divided into segments of shorter time ranges, and best models were obtained for segmented data where more variability in solar radiation and humidity were present (i.e., after sun-rise, before sun-set) than other segments. To consider time delay in the response of $CO_2$ concentration, concept of time lag was implemented in the regression analysis. As a result, there was an improvement in the performance of the models as the coefficients of determination were 0.93 and 0.87 with segmented time frames for sun-rise and sun-set periods, respectively. Validation tests of the models to predict $CO_2$ emission from soil showed that the developed empirical model would be applicable to real-time monitoring and diagnosis of significant factors for $CO_2$ enrichment in a soil-based greenhouse.

This study was performed to evaluate the mechanical properties of four commercially available veneering resin composites for crown (Dentacolor: DC, Artglass: AG, Esternia: ET and Targis: TG). According to the manufacturer's instructions, disc specimens were fabricated in a teflon mold giving 12mm in diameter and 1 mm in thickness. All specimens were immersed in distilled water at 37℃ for 30 days. An indentation test of 68-degree trigonal diamond pyramid was made under 98.06 mN load for 15 seconds. Hardness numbers, charateristic indentation depths, flow and permanent deformation were measured and compared statistically by ANOVA and Tukey's multiple range test. The results obtained were summarized as follows; 1.The highest hardness value of 87.4 was observed in the ET group and the lowest value of 11.8 was observed in the DC group. Hadness values showed no sinificant difference between the AG group and TG group, but others showed the significant difference beween groups (p<0.5). 2.Flow value of the ET group was significantly lower than those of the AG and TG groups of hybrid composite for crowns. 3.Percent strain during the indentation was the lowest in the DC group and the highest in the AG group, but there was no significant difference in each experimental group (p>0.05). 4.The relationship between the hardness number and flow during the indentation was a negative linear on a logarithmic scale.

α-sexithienyl(α-6T) thin films were deposited by Organic Molecular Beam Deposition(OMBD) technique, where the α-6T was synthesized and purified by the sublimation method. The thin films of the α-6T were deposited under various deposition conditions. The effects of deposition rate, substrate temperature, and vacuum pressure on the formation of these films have been studied. The molecular orientations of α-6T films were investgated with the polarized electronic absorption spectroscopy. The molecules in the α-6T film deposited at a low deposition rate under a high vacuum were aligned almost perpendicular to the substrate. The film deposited at an elevated substrate temperature (∼90℃) showed higher conductivity than the film deposited at room temperature.
