Purpose : This study evaluated the impact of the presence and aspect of mandibular third molars to the mandible angle fracture or condyle fractures in Korean. Materials and Methods : A retrospective study was designed for patients attending the division of Oral and Maxillofacial Surgery, Kang-dong sacred heart hospital for treatment of mandibular fracture from January 2006 to September 2010. The primary variable was the presence of mandibular third molar and the secondary variable was the aspects of third molar impaction. Mandibular third molars were classified by the impaction depth and the available space as Pell & Gregory system. Outcome variables were the presence of mandibular angle fracture or condyle fracture. Also the source of trauma, age, sex were studied. Hospital charts, radiographs were used for study. Statistic analysis was done with descriptive statistics, the X2-test, linear-bylinear association. P value under 0.05 was considered significant statistically. Results : The number of involved patients was 86. The ratio of male to female patients was about 9:1 for angle fracture and 7:3 for condyle fracture. The most common source of trauma was assault for angle fracture and fall down for condyle fracture. The presence of mandibular third molar increased frequency of angle fracture and decreased condyle fracture with larger impaction depth. But available space of mandibular third molar did not show high association with angle or condyle fractures. Conclusion : Preventive extraction of mandibular third molar is recommended for patients with high risk of angle fracture. Male patients at their third decade or martial artists, police officer could be the case. But it is not recommended for patients with low risk of angle fracture and high risk of condyle fracture relatively. Elder female patients without any symptom on their third molar could be the case.

This paper was carried out to investigate the kinds of vascular plants and their frequencies appearing in the books of the elementary school; "wise life" and "nature". in the books of the high school; "biology". These investigations were compared the kinds of the garden trees and their frequencies of 10 elementary. 4 middle. and 5 high schools and total 19 schools in chinhae city and the vasular plants writtern in the biology text books as a basic research for the teaching gardenization of school gardens from March. 1984 to August. 1988. The results were summarized as follows: 1. The biology text books appeared total 214 kinds of the vascular plants. According to classification, they were 91 families, 182 genera, 192 species, 21 varieties , and 1 forma. These consisted of 33 kinds in the books of the elementary school; "wise life" and "nature " , 63 kinds in the books of the middle school; "general science", and 208 kinds in the books of the high school; "biology". In all the biology text books the woody plants were total 77 kinds or 37 families, 58 genera, 68species, 8 varieties, and 1 form. Among them, the woody plants of 8 kinds in the elementary school, 22 kinds in the middle school, and 73 kinds in the high school were contained. 2. Total frequency of vascular plants appearing in the biology text books was 1576 times. Among them, the vascular plants of 238 times in the elementary school, 268 times in the middle school, and 1074 times in the high school appeared. Average frequency per species was 74 times in total species of all the biology text books, 7.2 times in the wise life and nature text books of the elementary school, 7.2 times in the general science text books of the middle school, 2.5 times in the biology text books of the high school. 3. The woody plants in school garden in Chinhae city were 165 kinds. According to classification, they were 53 families, 96 genera, 126 species, 33 varieties, and 6 forma in the gardens of total 19 schools. The woody plants of 139 kinds in the gardens of 10 elementary schools, 77 kinds in the gardens of 4 middle schools, and 114 kinds in the gardens of 5 high schools were planted. 4. Total frequency of kinds planted in 19 schools and average frequency per species was 1019 times 6.2 times. The woody plants appearing in the garden of schools were 8 kinds of Cedrus deodara, Juniperus chinensis var. kaizuka, J. chinensis var. globosa, Rosa hybrida. Puxus microphylla var, koreana, Hibiscus syriacus, Euonymus japonca, and Forsythia koreana, 11 kinds of Ginkgo biloba, Chamaecyparis obtus, C. pisifera var. squarrosa, Thuja orientalis, Yucca recurrifolia, Platanus orientalis, Prunus yedoensis, Ilex crenata var. microphylla, Acerplantanum var. palmatum, Camella japonica, and Viburnum aieabuki were 80% or over in frequency appearing in the gardens of 19 schools. 5. Total individuals appearing in the gardens of 19 schools were 24531 trees. Average individual number per school was 1291 trees in all the schools, 1562 trees in the elementary schools, 14455 trees in the middle schools, and 625.8 in the high schools. Average individual number per species was 148.7 trees in all the schools, 112.4 trees in the elementary schools, 75 trees in the middle school and 27.4 trees in the high schools. The greatest individual number among 19 schools in Chinhae city was 3994 in Daeya elementary school. The smallest individual number among 19 schools in Chinhae city was 271 in Chinhae comprehensive senior high school. 6. The woody plants appearing 1000 trees or over in the gardens of 19 schools were T. orientalis(4075), F. koreana(1986), E. japonica(1915), Rhododendron obusum(1730), H.syriacus(1509), C. obtus(1294), J.chinensis var. globosa(1112), and P. microphylla var. koreana(1043). These 8 species were 43.2% of total individual number. The ever green trees appeared 43.0% in the species numbers and 74.2% in the individual number. 7. The woody plants in all the school garden were 165 species in total. Average species number in each school were 53.4 species in total schools, 59.8 species in the elementary schools, 37.2 species in the middle schools, and 53.6species in the high schools. The greatest species number among 19 schools in Chinhae city was 84 species in Chinhae senior high school. The smallest species number among 19 schools was 21 species in Chinhae comprehensive senior high school. The woody plants appearing in the biology text books among 165 species growing in the school gardens in Chinhae city were 46 species. These species numbers were under 21.0% of vascular plants and 59.7%of woody plants appearing in the biology text books. These species number of the woody plants growing in 19 school gardens among the woody plants appearing in the biology text books were 4.6 species in the elementary schools, 3.2 species in the middle schools, and 12 species in the high schools. These species numbers were under 57.7%, 14.1%, and 16.4% in the numbers of woody plants of the biology text books and 13.9%, 5.1% and 5.8% in the number of vascular plants of the biology text books. 8. The authors could find out that the plants planted in the school garden were not suitable to use for the teaching material plants because of planting only the woody plants of school garden for landscape rather than plants for teaching materials. Therefore some of the improvement for the teaching material garden of school were issused in the discussion.

This study investigated the effect of the tempering before aging on the precipitation of Laves phase and mechanical properties of 10Cr-6W and 10Cr-6W-3Co ferritic heat-resistant steels. Laves phase was precipitated by aging, which increase tensile strength but decreased elongation and impact value. Toughness was rapidly decreased by the presence of the very fine disk-like Laves phase precipitated at early aging stage. Strength and impact value were decreased by tempering treatment and that is due to the increase of the particle number per unite area and to larger particle size of Laves phase. Laves phase increased by adding Co, and consequently strength was increased and elongation and toughness were decreased. (Received February 26, 2004)

강동우,박규은 濟州大學校 師範大學 科學敎育硏究所 1988 科學敎育 Vol.5 No.-

A series of experiment is performed to measure radon concentration in the near-surface soil gas at the four locations(Cheju-si, Seoguipo-si, Taejeong-eup, Seongsan-eup) in Cheju Island, using CR-39 detector placed inside radon cups. Two types of radon cups are installed in shallow holes of about 15㎝ in diameter and 50 ㎝ in depth. The optimum etching conditions, ie, the concentration of NaOH solution, etchant temperature and etching time, are found to be 6.25N, 70℃ and 5.5hours for CR-39 detector. A typical conversion factor of radon cup is calculated as 1 track/㎣·30 day= 1.594 pCi/ℓ Average radon concentration over 30 days measured in Cheju Island from May 1. 1987 to April 23. 1988 are 84.33±7.15 pCi/ℓ for open radon cups and 45.61±4.93 pCi/ℓ for closed radon cups.
