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.

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.

우리나라 主要河川의 感潮區間에서의 水位觀測은 1910年代부터 시작되었으나 感潮區間의 潮汐變化를 判別키 위한 이 長期資料의 徹底한 分析은 遂行된 바 없다. 本 硏究에서는 利用可能한 漢江, 錦江感潮區間에서의 5個所(顚類, 金浦大橋, 玉浦, 笠浦, 江景)의 感潮水位資料를 分析하기 위한 初期努力이 試圖되었다. 原記錄曲線으로부터 每時間別로 編輯된 水位資料로부터 統計的 變數들과 潮汐의 調和常敎를 구했는데 檢討結果에 의하면 旣存水位資料들은 不適合한 觀測體系 및 記錄體系 때문에 資料의 質은 극히 不良하였다. Observations of the water levels in the tidal reaches of major rivers in South Korea have been made since 1910s. But these extended records have never been subjected to intensive analysis to identify the tidal variation in the shallow rivers. In the present study, an initial attempt was made to analyze the available tidal data at five gauging stations(Jeonryu, Kimpo Bridge, Okpo, lbpo and Ganggyeong) in the Han River and the Keum River. Statistical parameters and harmonic constants were obtained from edited hourly water levels taken from original water level curves. It was found that existing data were seriously corrupted by improper measurement and recording system.

Fleet sizing and empty equipment redistribution are two of the most critical problems in managing a fleet of equipment over a transportation network. Where the demand pattern followed the compound Poission process(CPP) which can be generated one or more at a time under homogeneous Poissio process(HPP), this paper presented a mathematical model to determine control parameters of a decentralized distribution policy and fleet size. In case of the pure hub-and-spoke system, a popular form of a logistics system, and validated this model by simulation. That is, where the number of demanded equipments followed geometric and binomial distribution, respectively, cost models on the pure hub-and-spoke logistics system with deterministic transportation time, which could be solved analytically, were established and analyzed. We also compared the deterministic case with stochastic one that the transportation time follows some probability distributions.

The aim of this paper was to evaluate a characteristics of serum lipids and lipoproteins concentration during acute exercise at graded exercise for VO2max test, at ventilatory threshold and below ventilatory threshold. The results and conclusion of this study is obtained as follows. 1. No significant difference followed exercise intensities of three types in serum total cholesterol. Also, it was not a significant difference following time course of continuous exercise at ventilatory threshold and below ventilatory threshold. However, it was shown a significant difference(p<.05) between resting value and exhaustion value at graded exercise test. 2. Serum triglycerides concentration was not significantly altered as compared to three types exercise intensities. Also, Serum TG concentration did not differ follows time course of continuous exercise at ventilatory threshold and below ventilatory threshold. However, significant difference in traded exercise test was found between resting value and exhaustion value(p<.01), and between exhaustion value and recovery 30 minute(p<.05). 3. Serum HDL-C concentration did not differ significantly from the corresponding value at graded exercise test, at ventilatory threshold and below ventilatory threshold. It was not shown a significant difference follows time course of continuous exercise at graded exercise test and below ventilatory threshold. However, significant difference was found between resting value and exercise after 30 min. (p<.01), and between resting value and exercise after 60 min. (p<.05) at ventilatory threshold intensity. 4. Serum LDL-C concentration showed no change at the graded exercise test, at ventilatory threshold and below ventilatory threshold. Also, it was not shown a significant difference followed time course as exercise continued for all intensity.

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%.

For the fundamental knowledge about the behavior of glass solder in the case of joining of ceramics, the wettability of glass on alumina were measured by sessile drop method. SiO_2-CaO-Al_2O_3 glasses were selected as examples of glass, and alumina of the various compositions were used as substrates. Contact angle of glass on 99% alumina didn't decrease with time at elevated temperature, while 92% alumina showed time-dependent property. It was the reaction between glass and 92% alumina that contact angle of glass on 92% alumina decreased with time.

The chlorination of ilmenite in the presence of activated carbon has been investigated in a horizontal silica glass tube with catalyst and non-catalyst. Results are as follows; 1. In both cases the pseudo first order kinetics on ilmenite has been observed with excess activated carbon and chlorine gas at 320∼900℃. 2. The mixture of CaCl₂-NaCl as a catalyst shows a significant effect on increase of the reaction rate. The rate constant for non-catalytic reaction is 7.4×10??(min.??) at 800℃ and that for catalytic reaction is 5.8(min.??) at 500℃. 3. The activation energies for non-catalytic and catalytic reaction are 15.6㎉/mole and 7.1㎉/mole, respectively. 4. A 99.902% TiCl₄ has been separated from the produced mixture of TiCl₄-FeCl₃ by the successive methods of leaching with n-heptane and distillation. But the product from the simple distillation has been found only 99.848% TiCl₄. 5. A further purification of TiCl₄ to 99.998% is carried out by distillation of 99.902% TiCl₄ that was mixed with antimony powder and sodium hydroxide.
