The purpose of this study is to compare the response of four commercially available soft denture lining materials to the growth of C. albicans in vitro. Twelve samples of each soft lining materials were made to a uniform size and volume(15×5×4㎜) and sterilized using ethylene oxide. The samples were individually placed in culture tubes containing 5㎖ of sterile SDB(sabouraud dextrose broth dehydrated) and 0.1㎕ of activated C. albicans(ATCC 10231). The culture tubes had been incubated in incubator at 37℃. Three samples of each material had been tested at 3, 21, 35 and 56 days to determine the number of adherent cells of C. albicans on their surfaces and the number of nonadherent cells in the broth associated with each samples. The data have been analyzed by ANOVA and Scheffe test. The results have been obtained as follows : 1. In growth patterns of C. albicans within soft lining materials, Molloplast-B and K-33 were significantly higher(p<0.01) compared with Coe-Soft, but there was no significant difference between Coe-Soft, Coe Super-Soft and Mollosil(p>0.05). 2. Molloplast-B showed significantly higher(p<0.01) amounts of C. albicans adhering to its surface than other materials under experimental conditions. 3. Generally, adherence was significantly increased until 5 weeks, and after then showed decreased pattern in all materials(p<0.01). 4. The C. albicans was able to penetrate the inner portion of all samples. Coe-Soft showed most amounts of invaded C. albicans, followed in order by Mollosil, Molloplast-B, and Coe Super-Soft.

The purpose of this study is to evaluate the effects of distal extension partial denture on the mandibular movement patterns and velocity. The subjects are 10 patients who have unilateral or bilateral distal extension edentulous area in maxillary and/or mandibular arches. Their mandibular movement patterns and velocity had been measured by Mandibular Kinesiograph(M.K.G.-K6 diagnostic system, Myo-tronics Inc. Seattle. WA. U.S.A.) once just before the treatment and 8 times every week since the dentures were placed. The data have been analyzed statistically by means of ANOVA and Tukey test. The results have been obtained as follows : 1. The placement of the dentures has reduced the amount of vertical and antero-posterior displacement in the habitual mandibular movement significantly(p<0.01). 2. The maximum opening and closing velocity and the mean opening and closing velocity showed no significant change with the placement of the partial dentures(p>0.01). 3. The velocity trace of maximum opening-closing movement has been more regularized and well-coordinated, and the number of clicks decreased continuously after placement of the dentures and showed stable patterns since the 5th week(p<0.01). 4. The left deviation has been decreased significantly after the placement of the dentures and showed no significant change since the 4th week. The right deviation has also been reduced, but there was shown no difference after the 1st week(p<0.01). 5. The crossover pattern has been most frequently observed in the frontal plane and the sagittal plane. It has not been changed with the denture placement and stabilized uniformly.

The opening of Korean port was in 1876 caused by a gunboat diplomacy of Japan. European countries were also supported them for their national benefits. However Korean representative did not understand the meaning of modern customs system and customs tax. This paper provides how to work for autonomous customs right with Korean archives through 「Korea-Japan Customs Tax Proposal」 written by Cho Byung-Ho who despatched to Japan in September 1881. Furthermore, the study of foreign customs staffs are also undeveloped subject in Korea. Therefore, this paper also analyzes the role of foreign customs commissioners and their staffs and Korean Maritime Customs" activity for 22 years. This paper deals with the character and meaning of the opening of Korean ports and foreign customs staffs and their duty and business.
