Newly developed curing units for the dental composite resins are claimed to result in optimum properties and short curing time. The purpose of this study was to detemine the curing effectiveness of the curing units, and to evaluate the relationship between the degree of polymerization and leachability of residual monomer. Three composite resins were tested (Z100; z100, Herculite XRV; HX, Heliomolar; HM). Disk specimens of 2 mm in thickness and 6 mm in diameter were cured with a plasma arc [Apollo 95E; at 1370 mW/㎠, for 5 sec.(A5), 10 sec.(A10), 15sec(A15)], halogen lamp [VIP; at 500 mW/㎠, for 13 sec.(V13), 26 sec.(V26), 40 sec.(V40)] and custom made light emitting diode [LED; at 500 mW/㎠, for 13 sec.(L13), 26 sec.(L26), 40 sec.(L40)]. Specimens were immersed in 75% ethanol for 7 days. Eluates of the composites were analyzed by a high-performance liquid chromatography, and the degree of polymerization of composites were determined by a Fourier transform infrared spectroscopy. To obtain the sufficient curing by a plasma arc, the curing time should be longer than 10 sec. When the same light energy was irradiated, LED showed similar curing performance to halogen lamp. The light energy and the degree of polymerization was not correlated (p>0.05), but the light energy and the leachability of residual monomer was correlated (p<0.05). The leachability of residual monomer (TEGDMA+BisGMA) depended on the degree of polymerization.

Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Accociated systemic problems are widespread undermining of surrounding tissues, Accociated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.

高麗 中期 儒學

文暻鉉 慶北大學校 東洋文化硏究所 1983 東洋文化硏究 Vol.10 No.-

This paper studies the development of Confucianism in the mid-Koryo˘ period by focusing on the interrelationship among the three institutions―the national academy(國子監). provate academies, and civil service examinations. The Koryo˘ dynasty promoted Confucianism in order to create a bureaucracy loyal to the king, and thus replace the aristocrats with this new elite. For this purpose, the court instituted the national academy as well as the civil service examinations. These in turn brought about the development of Confucianism. Another salient feature of this period was the growth of private academies. Founded by eminent scholar-officials who had been in charge of civil service examinations, these private institutes surpassed the national academy in prestige and made remarkable contributions to the development of Confucianism. Their roots can be found in the Hwarangdo tradition of Silla.

Obesity is growing problem in Korea. We had a case of bariatric surgery during gastric cancer operation. Patient was 29 year old Korean lady with early gastric cancer located in the lesser curvature side of the middle 1/3 of the stomach. Her body weight was 89 kg, height 163 cm, and thus body mass index was 33.5 kg/m2. Preoperative blood pressure was 130/90 mmHg, hemoglobin 12.9 g/dL, total lymphocyte count 3,280/mL, serum albumin 4.3 g/dL, CEA 1.1 ng/mL, CA 19-9 9.1 ng/mL, and alpha fetoprotein 2 ng/mL. Another associated disease was right thyroid follicular neoplasm. The chest X-ray was normal. After IM injection of 2,500 units of heparin 30 minutes before the induction of general anesthesia, she received curative subtotal gastrectomy and Roux en Y gastrojejunostomy when a malabsorption loop of 120 cm jejunum was incorporated between the Treitz ligament and the end to side jejuno-jejunostmy site at May 29th 2006. Her postoperative course was uneventful except a minor wound seroma and the elevations of serum amylase(up to 4 folds) and lipase(up to 2 folds). She lost her body weight 9 kg in 5th, 21 kg in 7th, and 27 kg in 10th postoperative months to became 61.5 kg. On follow up exams in July 2008, she gained 4 kg to overcome her weakness and fatigue. From the above result, the incorporation of a malabsorption loop during reconstruction phase of gastric cancer operation was a good option for obese gastric cancer patients especially in cases of early gastric cancer.

This study was conducted to examine middleㆍhigh school 720 students in seven regions of middleㆍsmall city and town, Myon for 2 months from March 2 through April 30, 2002 in order to realize a side of school health education in middleㆍhigh school and health education need as well as health education specialist in school in the future. The results of this study can be summarized as follows. 1. Health condition is now 'normal' is 51.0%, 'good' is 45.0%, 'not good' is 4.1% and health condition of children is good as much as education level of mother is higher. 2. Experience to learn health education in school for one year recently is 'no' is 39.6%, 'don't know' is 32.6%, 'yes' is 27.8% and it represents health education in school doesn't work well and experience to learn health education is lower and lower in town and Myon. 3. Health education ways to work in school now are 'Movie, Video, Slide' is 40.7%, 'education as groups of nurse-teacher' is 38.6%, 'to distribute health education material and book' is 7.7%, 'education by setting an example' is 3.4%, 'the others' is 9.7%. 4. Time of appropriate health education for one time is 'about a hour' is 56.7%, 'about 30 minute' is 33.8%, 'about two hour' is 7.6%, it represents this situation is because of what students' time is lack and burden about a curriculum in an education administratin and school classed of a focused school score. 5. The average score of satisfaction of health education in school is 16.99±0.58, 'men' is 1.79±0.60, 'women' is 1.61±0.55 as the distinction of sex, satisfaction level of men is higher than women. 6. Learning route about health information is 'through mass media' is 59.9%. 'through family, friend' is 15.0% 'health education lecture' is 7.2%, 'printing media' is 6.1%, 'medical institution' is 5.6%, 'the others' is 5.1%, 'public health center' is 1.0%, 'through mass media' is the highest percent as each 59.1% and 60.6% in all of men and women. 7. The most efficient education way of health education is 'movie, video, slide' is 32.6%, 'health education specialist who works school' is 21.9%, 'school health education by nurse-teacher' is 16.0%, 'way through mass communication' is 11.6%. 8. The appropriate health education specialist in the future is 'health education specialist who has qualifications' is the highest as 64.5%, 'nurse-teacher' is 12.4%, 'medical personnel(doctor, a physician of oriental medicine etc.,)' is 11.0%, 'staff in public health center' is 7.2%, people in other regions(health and medical professor etc.,) is 7.0%, it represents school health education is not actual and is formal now in second hand. 9. The most necessary health education program is 'program of stress solution' is the highest as 24.9%, 'program of no smoking' is 22.7%, 'sexual education program' is 19.8%, 'school violence program' is 8.8%, 'isolate from their friends prevention program' is 8.0%, solution program of stress which gives student by school score was very necessary. Therefore, school health education is formal and inefficient because school education focuses on an entrance exam, so middleㆍhigh school students decrease concern and interest about health education. Furthermore, reliance is gotten down about nurse-teacher who takes charge of school health, a charged person of school health education wants more chargeable health education staff. And a solution program of stress that gives students by school score was very necessary. According to active concern and planned, systematic school health education is necessary to give right health knowledge, health maintenanceㆍpromotion and setting of appropriate health education specialist is very urgent.

문성경,최현섭 慶熙大學校 1993 論文集 Vol.22 No.-

Effect of simulated acid rain on the chlorophyll contents, photosynthetic rates, dark respiration rates and growth of Phaseolus vulgaris and ecophysiological changes were studied. The results were as follows: 1. Effect of simulated acid rain of pH 2.0 on treated plant was highly significantly different in total chlorophyll, chlorophyll a contents and photosynthetic rates compared with those of control group. 2. There was no significant difference in effect of simulated acid rain on chlorophyll b contents and respiration rates among four groups. Stability against chemical stress for chlorophyll b content and respiratory rate were higher than that for total chloropyll, chloropyll a content and phtosynthetic rate among four groups. 3. Effect of simulated acid rain with pH 2.0 on the growth of plant was highly significant. The third leaf of pH 2.0 group which emerged after treatment of simulated acid rain was significantly different from those of other groups. 4. There was significant reduction of the stem growth on early stage of the growth in pH 2.0 group. The growth of root in pH 2.0 group was reducted significantly different than that of control. 5. The LDRs of pH 2.0 treated group increased 5th days after teratment. The SDRs of pH2.0 treated gruop decresed 12th days after treatment. The RDRs were not significantly different among four groups, through experimental period.

Many full searchblock matching (FSBM) architectures have been proposed for the motion estimation. However, the FSBM architectures need many computations and a lot of external memory accesses which are the main source of the power consumption. We propose an efficient low-power architecture for the full search block matching (FSBM) motion estimation by eliminating unnecessary computations and data reuse. Implementation results show the proposed motion estimator can save maximally about 9.3% power dissipation than a previous motion estimator.
