The purpose of this study was to investigate the association among nutrient intakes and health-related lifestyles with cardiovascular disease risk assessed by blood lipid profile according to Apolipoprotein E genotypes. Middle-aged industrial male workers who had completed their annual medical examination were recruited and data of 675 subjects who finished the nutrient survey were used in the analysis. Anthropometric parameters, dietary assessment (FFQ), health-related lifestyles and blood profiles were used for statistical analyses. Apo E genotype groups were classified into the following three genotypes: Apo E2 group (including E2/E2, E2/E3, E2/E4), Apo E3 group (including E3/E3), Apo E4 group (including E3/E4, E4/E4). The frequency of Apo E2, E3, and E4 allele were 13.3%, 75.0% and 11.7% respectively. There were no significant differences in the anthropometric parameters depending on different Apo E genotypes. Also, no significant differences in the nutrient intakes were found according to the genotype groups. The nutrient intakes of all subjects were similar to or higher than the level of KDRIs (Dietary Reference Intakes For Koreans) except for intakes of calcium (67.44% of KDRIs), vitamin A (73.83% of KDRIs) and vitamin B2 (78.02% of KDRIs). Also, there were no significant differences of health-related lifestyles according to Apo E genotype groups. As for the lipid profiles, Apo E4 group had significantly higher total and LDL-cholesterol concentrations than the Apo E2 group (p < 0.05). We confirmed that plasma total and LDL-cholesterol concentrations were greatly influenced by Apo E genotypes. However, nutrient intakes and health-related lifestyles were not associated with Apo E genotypes.

허경숙,허성주,조인호 단국대학교 치의학연구소 1991 논문집 Vol.3 No.-
The magnets were widely used to increase the retention of overdentures. The purpose of this study was to compare the break load between overdentures and edentulous models. For this study, Model former(U-402) was used for model fabrication and four different magnets were used for evaluation of break load. The artificial saliva was used between overdenture and model. Breakaway loads were tested with an Instron 1122 at a speed of 2mm/min. The results were as follows. 1. The retentivee forces complete dentures with artificial saliva were than the retentive forces of complete detures without artificial saliva. 2. Magnetic overdenture with artificial saliva showed best retentive force, magnetic overdenture without artificial saliva showed the next retentive force, and the complete denture without artificial saliva showed the worst retention. 3. As the magnetic sizes increased, the retentive forces of magnetics were increased. 4. The retentive force of nipple shape magnet is greater than the retentive force of flate shape magnet in the same size.

황악산에서 채집된 느타리 버섯의 분류를 위하여, 4종류의 느타리과에 속하는 버섯들과 함께 미토콘트리아 DNA를 분리하여 여러 제한효소로 처리 후 나타나는 절편들의 양상을 비교하여 계통분석을 수행하였다. 여러 제한효소 중 4가지의 제한효소를 선택하여, 절편을 얻은 후 NTSYS-pc program을 사용하여 분석한 결과, 채집된 버섯은 형태학적으로 느타리와 유사하였지만, RFLP 법으로 판단할 때 오히려 사철느타리와 더 연관성이 있는 것으로 나타났다. 따라서 보다 객관적인 분류를 위하여 형태학적 분류만으로는 한계가 있고, 분자생물학적인 분석 등 다양한 기준에 의해서 수행되어야 한다고 판단된다. To identify the strain (TUM004) which was isolated from Mt. hwangak, the restriction enzyme analysis of mitochondrial DNA was accomplished using four different strains of Pleurotus as a standard strain. Pattern of fragments generated by 4 different restriction enzymes (BamHl, EcoRl, Hindlll, Xdal)was analyzed by using NTSYS-pc program. Results showed that TUM004 was more related to Pleurotus florida rather ,than to Pleurotus ostreatus. Results also imlpy that RFLP of mitochondrial DNA is a good classification system to identify the unknown strain to the genus level.

Photosynthetic bacteria (PSB) attract considerable interest as useful microorganisms; nevertheless, a generalized culture technique has not been previously reported owing to difficulty in their cultivation. Therefore, a simple culture technique suitable for public use was investigated. Among the PSB tested, the strain Rhodobacter azotoformans EBN-7 was the most suitable for scale-up production because it showed the highest specific growth rate (0.20 h<sup>-1</sup>) on basal medium. In scale-up cultivation (500 L), R. azotoformans EBN-7 showed 4.50 × 10<sup>10</sup> colony-forming units mL<sup>-1</sup> (number of viable cells), dry cell weight of 26.8 g/L, and a specific growth rate of 0.15 h<sup>-1</sup>. Cultivation using this final culture broth (as seed culture) in a 15 L simple reactor was successful, with maintenance of cell activity evident. For use as seed culture, the maximum allowable preservation period of R. azotoformans EBN-7 at 4℃ was 3 months. When R. azotoformans EBN-7 cultivated in a simple technique was applied to shrimp aquaculture water, NH<sub>4</sub><sup>+</sup>-N was reduced from 0.61 mg/L to 0.24 mg/L (by 60.7%) in 4 days in comparison with the control. Thus, this simple culture technique using R. azotoformans EBN-7 has the potential for a good removal efficiency of NH<sub>4</sub><sup>+</sup>-N, making seed culture easier and suitable for public use.

In this paper, we design and implement a service system for mobile devices to utilize the integrated underground geospatial information map in underground exploration fields. The field utilization service system for mobile devices is designed to visualize tiled maps, 3D terrain information, underground structures, underground facilities, and ground information provided by the Integrated Underground Geospatial Information Map Management System according to current position. And It is designed to reflect the results obtained from field exploration in real time. Also, the proposed system is implemented to transfer and visualize the integrated underground geospatial information map in the form of a glTF format due to constraints on wireless networks and device characteristics of mobile devices. Implemented mobile service systems can prevent accidents in underground exploration field from occurring by providing users with accurate and integrated underground geospatial data by visualizing maps and geospatial objects in three dimensions at underground exploration fields. In addition, updated underground geospatial data is transmitted in real time to the Integrated Underground Geospatial Information Map Management Systems, which can maintain up to date and accuracy.
