Several problems occur including lack of humanity, confinement of creativeness, lack of independent learning capability, when elementary students are taught computer, since the they learn only basic functions of computer in general. Accordingly, it is required to have subject-integrated textbook with which they learn curriculum and nurture the humanity as well as creativeness, while studying functions of computer. In light of this, I plan to develop computer textbook, which divided the contents of Hangul 97 and Windows 98, operation system, per subject, and organized them in the order of question to study for himself, part to learn function, formation evaluation, study on subject integration study related to curriculum, part to raise creativeness, and supplementary study, after extracting the contents of curriculum, creative factor and humanity factor suitable for each subjects. By realizing the subject-integrated textbook that enables the interaction by taking advantage of dynamic feature of web, this textbook aims to raise the humanity and creativeness while learning the functions of computer.

N/A There is little, if any, difference in the haling time of large cystic cavities of the Jaws, regardless of the techinique used. Many authors advocates the use of bone and alloplast (bone substitutes) in the filling of osseous defect after cyst enucleation, but there are many advantages and disadvantages. None of materials has been universally acceptable. The bane regeneration in the healing of cysts has, of course, always been though to be influenced decisively by location, sue and shape of cyst and of patient. It is too belived that functional stimuli, though this cannot be proved with certainly, are partially responsible for the rapid regeneration. On the basis of extensive literatures it too be under the impression that the decisive bone regeneration occurs within the first two years.

N/A The purpose of this study was to observe the clinical appearances and the hematologic alterations in rabbits when the anticancer drugs: Bleomycin, Cyc1ophosphamide, Methotrexate and 5-Fluorouracil (B-CMF) of the clinical and experimental doses are administered to the rabbits. For this study, the 20 rabbits, weighing about 2kg, were used and divided into the clinical and experimental dosage groups. In the clinical dosage group, B-CMF regimen was initiated with bleomycin 0.05 mg/kg per day for four days. 24 hours rest period followed the bleomycin, and then, a combination of cyclophosphamide 20 mg/kg, 5-fluorouracil 40 mg/kg per day for five days, and methortrexate 2 mg/kg on days one and five was given. All of these agents were given intramuscularly. The experimental dose was 1/8 of the clinical dose and it was the same schedule of administration as the clinical dosage group. The clinical study was to observe alopecia, mucositis and miscellaneous clinical changes everyday. The laboratory study was to observe hematologic changes on the 1st, 5th, 11th, 14th, 17th, 20th, 25th and 28th day from the 1st day of experiments. The rabbits were anesthetized by injecting the Ketamine Hcl of 7 mg/100grn of body weight intramuscularly. When the rabbits were anesthetized, 1ml blood was collected from the femoral and jugular veins. The blood samples were immediately used for the counts of the r blood cell, white blood cell, hematocrit, hemoglobin and platelet, and was made smear for the differential counts of white blood cell. The counts of the red blood cell, white blood cell and platelet were made by standard method and the counts of differential leukocyte were conducted through the examination of blood films with Wrights stain, The hemoglobin concentration was determined with Hemophotometer (Fisher Co.) and the hematocrit value was determined by the capillary hematocrit method. The mean corpuscular volume (M.C,V), mean corpuscular hemoglobin (M.C.H.), and mean Corpuscular hemoglobin concentration (M.C.H.C.) were calculated by the Wintrobe method. The following results were obtained: 1. Mucositis of degree 1 (oral redness) was observed on the 14th and 1.7th day, and was re- covered on the 25th day, 2. Alopecia was partially observed from the 5th day and was moderately severe from the 8th day. 3. All of the clinical dosage groups were died on the 7th and 8th day. Three of the experimental dosage groups were died w the 9th and 10th day, and their mortality rate were 30%. 4. In the experimental dosage group, the counts of the white blood cell and platelet were significantly reduced on the 14th and 17th day. 5. Neutrophil was slightly reduced on the 14th, 17th and 20th day, but others were within normal range. 6. Each blood count returned to the pre-experimental state n the 25th and 28th day.

Residual maxillary alveolar cleft defects are frequently encountered in cleft palate patients. Bone grafting to the area between the ages of 7 and 11 may be considered. Advantages of bone grafting are that unerupted teeth in the area erupt through the graft, the arch is stabilized, and the oronasal fistula is closed. Bone grafting of alveolar clefts in the cleft palate patient must be done with two objectives in mind: (1) Restoration of form and (2) Restoration of function to the alveolar cleft. This is a case report of the oronasal fistula with alveolar cleft which was successfully treated by surgical correction.

N/A Many researches have concentrated recently on the resorbable implant materials, for the implant materials have a difficulty in the physiological and structual affinity around the surrounding tissues. The main purpose of biodegradable ceramic is to fill a space as well as to eliminate the need for a metallic implant. This material would not only provide a matrix for bone formation but, by concurrent resorption or degradation, would disappear from the site of implantation. The basic composition of biodegradable ceramic is calcium phosphate and the representative material is tricalcium phosphate. The author investigated this material using rabbits and dogs far clarifying the correct mechanism of the biodegradation, and further information of new bone formation. On the basis of this I have studied to find possibility of development about ideal alloplastic materials. Bony defects, 0.5cm size, were created in the femur of rabbits and the granule type, tricalcium phosphate, Ca3(P04)2, Synthograft, Miter Inc., was implanted for investigating the tissue reaction through 12 weeks, and another experiment was performed in the dogs in the same manner as the rabbits, except bony defects, 2cm size for studing the degree of the new bone formation during the 6 weeks. The results were examined with light microscope for histologic appearances with conventional stainable specimen, and microradiographic examination was performed with undecalcified specimen for the degree of calcification and stage of osteon maturation. The results were as follows, l. In both rabbits and dogs, tricalcium phosphate did not induce the abnormal tissue reaction and the wounds were healed normally. 2. Tricalcium phosphate particles began to have affinity with surrounding tissues from the 1st week and the fibrous invasi0e. was represented directly to the particle surface. 3. Replacement of tricalcium phosphate was represented with the disappear of it concurrently and this material developed the matrix for new bone Formation and was ossified directly. 4. The matrix for the new bone formation is resemble to acellular osteoid and the calcified trabecular bone was replaced. 5. In the disappear of this material, were not related the specific giant cells and macrophages. 6. In microradiogram, the calcification of new bone revealed a similar density with the radiopaque tricalcium phosphate from the 3rd weed, with time the formation and maturity of the new bone were manifested more distinctly than the control group. 7. The radiodensity of tricalcium phosphate particles has not specific change through the experiment period. 8. The small amount of tricalcium phosphate particles was remained at the implant site of bone marrow even at 12 weeks.

Osteogenic sarcoma of the jaws is a peculiar entity within the content of the malignant bone tumors of other sites. It is considered quite rare in the jaws, where it comprises only 6.5 to 7.4 percent of cases. Entities such as Paget s disease of bone, fibrous dysplasia, osteogenesis imperfecta, and trauma have been considered predisposing factors to osteogenic sarcoma, but this relationship has not been extensively studies in the jaws. Treatment of this tumor is radically resection as early as possible. The overall 5 year survival rate for jaws were 35 percent after surgery. Our result showed that radical resection and postoperative irradiation is the best therapeutic procedure. Finally, if palpable cervical nodes are present, suprahyoid homolateral neck dissection should be improved survival.
