The treatment, management and long-term retention of mandibular molar teeth exhibiting furcation invasions always have been a challenge to the discerning general dentist or dental specialist. This is especially true when the furcation involvements has progressed to a class Ⅲ furcation. This study presents and describe various therapeutic plans available for class Ⅲ furcation invasions in mandibular molars, discussing the advantages and disadvantages of each approach. This study focus particularly on a surgical technique called "tunneling'', which is performed to describe the remaining soft and hard tissues in the furcal area ; this, in turn, allows access for effective oral hygiene and maintenance. The objective of this study and subsequent case report is to discuss and illustrate the tunneling procedure as a treatment alternative for mandibular class Ⅲ furcation invasions.

Cleft lip and palate is one of the congenital anomalies which need comprehensive and multidisciplinary treatment plan because 1) oral cavity is an important organ with masticatory function as a start of digestive tract, 2) anatomic symmetry and balance is esthetically important in midfacial area, and 3) it is also important to prevent psycho-social problems by adequate restoration of normal facial appearance. There are many different protocols in the treatment of cleft lip and palate, but our department has adopted and modified the Z□rich protocol, as published in the Journal of Korean Cleft Lip and Palate Association in 1998. The first challenge is feeding. Type of feeding aid ranges from simple obturators to active orthopedic appliances. In our department we use passive-type plate made up of soft and hard acrylic resin which permits normal maxillary growth. We use Millard's method to restore normal appearance and function of unilateral complete cleft lip. In consideration of both maxillary growth and phonetic problems, we first close soft palate at 18 months of age and delay the hard palate palatoplasty until 4 to 5 years of age. When soft palate is closed, posterior third of the hard palate is intentionally not denuded to allow normal maxillary growth. In hard palate palatoplasty the mucoperiosteum of affected site is not mobilized to permit residual growth of the maxilla. We have treated a patient with unilateral complete cleft lip and palate by Ajou protocol, which is a kind of modified Z□rich protocol. It is as follows: Infantile orthopedics with passive-type plate such as Hotz plate, cheiloplasty with Millard's rotation-advancement flap, and two stage palatoplasty. It is followed by orthodontic treatment and secondary osteoplasty to augment cleft alveolus, orthognathic surgery, and finally rehabilitation with conventional prosthodontic treatment or implant installation. The result was good up to now, but we are later to investigate the final result with longitudinal follow-up study according to master plan by Ajou protocol.

The objective of this research is to find out the influencing factors to recur oral cancers. The outcomes of 85 patients(male: 62 patients, female: 23 patients) with oral cancer who were not treated any pre-operative radiotherapy, chemotherapy or previous oral surgery, other than routine dento-alveolar procedures and a recent diagnostic biopsy were analysed retrospectively. Actuarial (life tables) survival analysis showed the 5 year survival rate was 58%, 52% for male patients, 72% for female patients. The patients who were under 50 years old showed 71% of 5 year survival rate, 51% of 5 year survival rate were above 51 years old group. Patients who were treated with elective neck dissection showed better prognosis which were shown 73% of 5 year survival rate than not neck dissection which were reveal 45% of 5 year survival rate. In TNM stage of patients, advanced stage showed worse prognosis, but only N stage did not suggest to judge good prognosis. Most patients were treated under postoperative radiation therapy and showed better prognosis.

An improved retinal tack can be used to fix the retina in complicated retinal detachment and proliferative vitreoretinopathy. We used the retinal tack made by biodegradable polyglycolic acid, polylactic acid and copolymers. The tacks with polyglycolic acid were placed in the retina the right eyes of 10 rabbits as group 1, with polylactic-polyglycolic acid copolymers as group 2 in each left eyes. We examined the absorption rates and degree of intraocular inflammation at 1 day, 1, 2, 4, and 8 weeks and compared both eyes. The tacks were absorbed with time in both eyes, but more rapid in copolymers. And there was no inflammation in both eyes. Now, this study will be a base on the drug delivery system in intraocular pharmacological and surgical management.

This is a retrospective study of 31 patients, who were diagnosed as bilateral TMJ internal derangement in consequence of magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) at Department of Dentistry, Ajou University Hospital, and who were compared clinical findings with radiological findings. The results obtained were as follows. 1. The average of the patients of bilateral TMJ internal derangement was 27.3 years with a range from 12 to 74 years, and 93.6% of the patients were youger than 40 years of age. The male-female ratio was 1 : 6.8, and the females of 20∼29 years were most common in 35.5%. 2. In the patients of bilateral TMJ internal derangement, the patients who complained clinical symptoms bilaterally were 38.7% and the patients who complanined clinical symptoms untilaterally were 61.3%. 3. The most common disc position of bilateral TMJ internal derangement was anterior disc displacement without reduction on both sides in 38.7%. The most common disc configuration of bilateral TMJ internal derangement was biconcave on both sides and amorphous on both sides in closed mouth, and was amorphous on both sides in open mouth. 4. In the patients of bilateral TMJ internal derangement, the joints which really showed clinical symptoms were most common in anterior displacement without reduction of 48.9%.

Purpose : The purpose of this study is to setup a standard treatment protocol in surgical correction of skeletal malocclusion with Angle Class III patients. We asessed the soft tissue changes according to skeletal changes of patients who undergone orthognathic surgery with bilateral split sagittal ramus osteotomy (BSSRO) and advancing genioplasty. Materials & Methods : The soft tissue change of 9 skeletal Class III patients was assessed after BSSRO and advancing genioplasty. The patient group was Class III who was surgically treated by BSSRO & advancing genioplasty. The average follow up period is 13 months with range of 6 and 30 months. All patients have undergone preoperative and postoperative orthodontic treatment. The assessment was devided into two groups. One was antero-posterior relationship and the other was vertical relationship of dimensional changes of soft tissue after orthognathic surgery. Results : In antero-posterior dimensional changes after surgery, the percentage of soft tissue change in comparison to hard tissue was 89%. Vertical ratio after surgery, 86% soft tissue changes were assessed.

In general, the efficiency of boiler varies with the loading rate, season and the operated year. When the boiler is operated in accordance with the maximum efficiency, it can be possible to save energy. In this experiment, the operating data of three boilers (two-drum D-type water tube boiler, capacity 30t/h, steam pressure 7.5 kg/cm2) were checked and calculated in order to know the amounts of evaporation and consumption of fuel oil, temperature (feed water, fuel oil, exhaust gas and air), the CO2%, the loss of exhaust gas and the calculated boiler efficiency. For the purposes of this study, the boilers were operated and six times checked with 45-100% of the loading rate in summer from 15th of July to 14th of August and in winter from 15th of December to 14th of january in the next for three years. The main results obtained from this study are as follows: 1.The maximum efficiency of boiler was decreased by 0.63% in summer and by 0.49% in winter in a year. 2.The average maximum efficiency of boiler was higher by 1.73% in summer (average 90.49%) than in winter (average 88.76%). 3.The economical loading rates showed 75% in summer and 80% in winter by No. 1 boiler, 85% in summer and winter by No. 2 boiler and 75% in summer and 80% in winter by No. 3 boiler. 4.The total average boiler efficiency with respect to 45-100% of the loading rate was higher by 1.39% in summer (87.84%) than in winter (86.45%). 5.The average temperature of exhaust gas was higher by 12.35℃ in winter (158.28℃) than in summer (145.93℃). 6.The average loss of exhaust gas was higher by 1.13% in winter (6.01%) than in summer (4.88%). 7.When No. 1 boiler was operated on the loading rate in accordance with the maximum efficiency, the fuel cost was down by 2,1000,000 won/ month in summer and 1.080,000 won/month in winter in comparison with± 5% of that condition.

We have studied the characteristics of wind over Pusan coastal area in order to precisely predict surface wind having an important effect on oil spill fate using the data on surface observation of Pusan, Kimhae and Gadeogdo island which are collected during the 3 years from 1988 to 1990. We also investigated the correlation of the surface wind between Pusan, Kimhae and Gadeogdo island. In both Pusan areas and Kimhae, the land and sea breeze occurs during the whole season except for winter. The occurrence frequency of land and sea breeze is significantly high from April to August. The correlation of surface wind between Pusan, Kimhae and Gadeogdo island surface wind is high in the daytime. The occurrence frequency of sea breeze in the Kimhae areas is higher than that in pusan on the basis of the present criteria. For monthly occurrence, Pusan has the highest occurrence frequency of the sea breeze in August and Kimhae has in May.
