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.

As a conclusion, although Aerobic exercise can not improve general fitness of the homekeeper but maintain previous fitness level and body shape.

보조학습도구로서 Mathematica를 이용한 학습모형 개발

강동식,강정우 제주대학교 1994 논문집 Vol.38 No.-

보조학습도구로서 컴퓨터는 매우 유용한 도구이다. 학생들은 문제의 중간과정에 많은 노력을 투자함으로서 문제분석이나 결과해석에 치중하지 못하는 경향이 있다. Mathematica를 이용하여 그런 노력을 완화시킬 수 있으며, 보다 많은 경우에까지 응용할 수 있어 물리개념을 확고하게 정립할 수 있다. 수업모델로써 세가지 예, 즉 Ohm의 법칙, 감쇠진동, 파의 중첩들을 제시하였다. As the assistant learning instruments, computer is a very usefoul tool. Students make great efforts in processing intermediate mathematical steps in solving the Physical probelem. Mathematica alleviates such efforts and students can make a further motice to the analysis of problems and to the interpretation of results. We propose the three learning models utilizing Mathematica as the assistant learning instrument:the Ohm's the damped oscillation, the superposition of waves.

The physical significance of the activity constant ζ, which is needed to describe electrodynamics of an isotropic medium, is discussed in electroconductive media and non-electroconductive media. In non-electroconductive media, where the sources of the charge density ℓ and current density J , and the conductance σ vanish, the speed of propagation and the refractive index of two circularly polarized transverse modes are different, and the physical phenomena called as the optical activity take place. Also in electroconductive media, in which energy of electromagnetic wave through the medium is damped, the phase velocity and the absorption coefficient of the electromagnetic waves depend on ζ . The skin depth and the angular frequency also depend on ζ .

광산에서 배출되는 광재폐기물은 산과 계곡에 투기 또는 매립되어 강우등에 의하여 주변 소하천을 오염시키고 있다. 따라서 본 연구는 광재의 물리적특성과 이화학적 특성을 조사하고 회분식과 칼럼식실험을 수행하여 오염물질의 침출특성을 고찰하고자 하였다. 실험결과, 다음과 같은 결론을 얻을 수 있었다. 1) 광재는 점토질 및 실트질의 크기를 지니고 있으나 점착력과 소성적 성질이 없는 사질토의 특성을 지니고 있다. 2) 광재의 투수계수는 대부분 10(???)³-10(???)cm/sec의 범위이며, 일반 사질토의 투수계수보다 낮음을 알 수 있었다. 3) 회분식과 칼럼식 용출시험의 결과, 대상 광산의 광재폐기물 일부에서 기준치 이상의 중금속농도가 침출되었으며, 이에대한 방지대책의 심각성을 알 수 있었다. 4) 광재 폐기물의 칼럼식 용출시험 결과 kg폐기물 당 인공강우 투여량 비가 증가할수록 침출수의 중금속 및 유해물질 농도는 크게 감소되어 어느정도 진행된 이후부터는 대부분 일정한 농도가 유지되나, 산성강우시 침출정도 및 침출시간은 지속되는 것을 알 수 있었다. 5) 광재는 많은 중금속과 유해물질을 함유하고 있으나 양적인면에서 자원화의 가치가 높을 것으로 판단된다. 따라서 광재내의 자원회수, 건설 재료등의 재활용및 자원화 연구가 필요하다. Tailing wastes producedat metal mines have been disposed of by dumping or landfiling in depression. Mine drainage developed at pile of the tailing wastes has high concentrations of various kinds of heavy metals and harzardous materials, and these contaminants are leached out from the tailing wastes by water infiltration or when they collapse. In this study, both batch test and column test were performed in order to investigate the physical and leaching characteristics of tailing wastes. The batch test results were compared with those by EPT and DLT, and column test was carried out at acidic and neutral pH ranges. The results showed that high concentrations of heavy metals and sulfate were contained in the leachate of the some tailing wastes. In column test, levels of heavy metals in the leachate produced during the initial rainfall period were found higher.

Photocatalytic inactivation of Microcystisaeruginosa was carried out with the TiO₂-coated pyrex hollow glass beads under the illumination of UV light(370㎚ wavelength). After being irradiated with UV light in the presence of the TiO₂-coated pyrex glass beads, Microcystis aeruginosa, known as typical cyanobacteria, lost their photosynthetic activity, and the colonies of Microcystis cells were completely separated into individual spherical one. Complete photocatalytic inactivation of Microcystis aeruginosa was obtained in about 30min. Photosynthesis activity of the cyanobacteria could be inhibited effectively after being reacted photocatalytically with TiO₂ immobilized hollow glass ball.

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)
