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.

In the hypercholesterolemic rats, the dietary effect of various fat and oils was investigated on total cholesterol, triglyceride (TG) levels in the liver, fatty acid composition of various fat and oils and tissues lipids. the result was as followed 1. All groups feeding of fat and oils did not significantly affect growth and food intake during the experimental perioud of 3 weeks. 2. The concentration of TG and total cholesterol in liver were not significantly different among all the groups. 3. Fatty acid composition of experimental fat and oils was determined. Soybean oil, perilla oil group were more than lard group in unsaturated fatty acid content. Poly unsaturated fatty acid content of file fish oil group was 15%, contents were remarkable than any other groups. 4. Fatty acid composition of liver tissue lipids was similar to fatty acid pattern of experimental fat and oils and were detected 14-17 kinds of fatty acid. Poly unsaturated fatty acid content of soybean oil, perilla oil and file fish oil groups were more than other groups, and file fish oil groups was abundant EPA. DHA content.

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.

Hydrogen Behavior in Ti-Added Reduced Activation Ferritic-Martensitic Steels

Hydrogen behavior and corresponding mechanical degradation were examined in TaTi-RAFM and EUROFER97 steels. Increased Ta content with Ti addition decelerates the hydrogen diffusion but increases the solubility in the lattice. It ismainly led by the higher fraction of Ta-rich MC carbides and dislocation density in TaTi-RAFM steel. Overall activationenergy of hydrogen trapping of investigated steels is evaluated to be 25.3 ~ 25.6 kJ/mol in the tempered condition. The activationenergy increases to nearly 30 kJ/mol when the steels are re-austenitized and quenched. Higher activation energy withincreased dislocation density indicates that the dislocation provides for trap site with higher activation energy than Ta-richMC carbide. Mechanical degradation by hydrogen with respect to the yield strength, tensile strength and uniform elongationcould not be observed in all investigated steels. The presence of hydrogen only has influence on the loss of post-uniformelongation. For a given charging time, the loss of post-uniform elongation is more remarkable in TaTi-RAFM steel due tothe larger hydrogen uptake.

The study was desigened to observe the effects of dietary fat and oils on lipid components in serum and liver of rats on hypercholesterolemic diet Male rats were fed for 4 weeks after divided into seven groups as basal diet, lard, sesame oil, soybean oil, corn oil, perilla oil and sardine oil. During the experimental period, all groups except basal diet group were fed cholesterol diet. The concentrations of total cholesterol, triglyceride, phospholipid and lipid peroxide in serum and liver were analysed with the HDL-cholestero1 level of serum The results were as follows. The level of total cholesterol in serum was the lowest on basal diet group, and soybean oil group was that in cholesterol added groups. The content of HDL-cholesterol in serum was significantly high on corn oil group, and lard, sardine oil in order. The ratio of HDL-cholesterol/ total cholesterol was considerably higher on basal diet and sardine oil group than any other groups. The concentration of total cholesterol in liver was the lowest on basal diet group, and those of sardine oil and soybean oil group were comparatively low The amount of triglyceride in serum was the lowest on soybean oil group, but basal diet group was the lowest in liver. The concentration of phospholipid in serum were remarkably lower on perilla oil, sardine oil and soybean oil group than basal, lard , sesame and corn oil group. Phospholipid concentration in liver was comparatively low on soybean oil group. The contents of lipid peroxide in serum and liver were high on sardine oil and perilla oil group.
