The purpose of this study was to restorate a patient who has a few remaining teeth with #15,23,24 supported Konus telescope denture in Maxillar and #44,43,33,34 supported Dolder bar retained overdenture in Mandible. Konus telescope and bar retained overdenture was taken better results in retention, support, stability compair with regular Removable partial denture. In Removable partial denture, the change of remaining teeth and edentulous ridge is natural. But Konus telescope and bar retained overdenture is a little effected in this change, so it is possiblble in long-term use. In cosider of patient's medical history and the possibility of additional tooth loss, Konus telescope denture can be easily repaired. Compaired with Konus telescope and bar retained overdenture showed high stability and easy cleansing because of rigid support, cross - arch splinting, and simple design. In delivery, patient had a difficulty with removal of denture and plaque control, but showed better condition, good oral hygienic care. Patient satisfied with denture functionally and esthetically. This study showed Konus telescope and bar retained overdenture was effective for treatment of patient remaing a few teeth in function, esthetic and psycologic satisfaction.

The medicinal plants used traditional medicines are classified into two groups. The first group is formulary medicine which have been recorded on authorized books, for example, kampo drug in Japan. The second group is the fork medicines. These medicinal plants production is 165 billion yen(about 1.5 billion dollar) and which rate to to total pharmaceutical production is about 3% in 1990. The number of important medicinal plants treated in the market is 124 herbs from the total 364 herbs for kampo durgs(210 preparations kampo durgs) and other propritetary drugs (agents for common cold, laxatives, gastrointestional and so on). The production of the Ginseng and Bupleurum Root are increased about ten times in last twelve years(1976 or 1988). The 80% of these medicinal plants are imported from China, Korea and Southern Asian countries. Then the Pharmaceutical Affairs Bureau of Ministry of Health and Welfare published "The Guideline of Medicinal Plant for Cultivation" for a quality control and a stabilization supply of 80 herbs. The first part(1992) of the guideline reported 5 herbs; Coptis Rhizome, Rehmannia Root, Bupleur, Root, Japanese Angelica Root and Rhubarb, The next part will be published following 5herbs; Cnidium Rhizome, Safflower, Coix seed and Fruiet, Platicodon Root and Zedoary.

This study aimed to grasp trends of the discourse for improving living conditions carried out since 1920's, when the sense for mending the irrationality of conventional living emerged in various magazines. Among the movement, women intellectuals played an important roles to discuss reforming daily life and unhealthy, inconvenient houseworks. This study found the ideological background and direction of this discourse, and estimated its important role for housing improvement, analyzing the contents of articles published in representative womens' magazines of the modern times. In the discourse, they thought that it was most important to make houseworks brief and efficient, and concentrated on building rational environment for houseworks. As reforming kitchen system, heating system (Ondol) should be separated from cooking system to improve hygienic and economical condition of houseworks. Reformed kitchen would be equipped with new installations for effectiveness, lightened by sunlight through windows, and finished floor with cement and drainage for sanitation. Also, they suggested new ways of living, planning modern houses with reformed kitchen system, thinking about moving path and distance of housewives. This discourse would be a foundation to the change of kitchen system up to now.

Purpose: This research aims to investigate into company workers' awareness of scaling and related factors and provide basic materials for setting up appropriate policies to improve the hygiene of the mouth of industrial workers and developing training programs for the worker's hygiene of their mouth, as part of researches to establish schemes for improving the workers's hygiene of their mouth. Method: Questionnaire was conducted by convenience sampling for 220 office workers belonging to H Group located in Seoul Metropolitan city over about 5 weeks between December 17, 2007 and January 20, 2008. The questionnaire for this study was constructed in consideration of general characteristics of the subjects, behaviors of the dental management. and scaling. The collected questionnaires were electronically processed using SPSS 12.0. Result: The followings are the findings of this research. First, in general, scaling is experienced by male unmarried worker in their 40s. whose monthly average income is 1.00-1.99 million won and have little interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is not good. Second, scaling is experienced once every six months by the worker in their 50s or older, who are college graduates and have much interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is good. Third. scaling is not periodically conducted because of high costs of it in terms of almost every parameter of general characteristics. Fourth, they have correct knowledge of scaling since they regard it as 'removing of plaque and tartar' in terms of every parameter of general characteristics. Fifth, the workers' sex (pE0.05), hygienic condition of the mouth (pE0.05) and knowledge of scaling (pE0.001) have a significant effect on their scaling experience. Conclusion: It is considered that dental health management should be continued by training of the importance of prevention through scaling as measure for dental health promotion of workers.

My purpose in the paper is to research on what is the most productive education method for the Students for Future Dietitian(SFD) to be applied during there field training & practice. Furthermore it is an attempt to elucidate what is the most necessary education program for the field training & practice for SFDs. Five questionnaires were given to SFDs dealing with nutrition purchase hygienic facilities and official management in order to check and evaluate the current situation and problems on the education of field training & practice for SFDs Also I chose 140 SFD's who had been working in the field for at least one week or one month in 1992 and statistical processing were utilized and analyzed by SAS package. One of the most notable problems SDFs faced with during meal planning it is the fact that they had been educated and requested for the cut of food expenditure rather than the supply of scientifically balanced-nutrition meals for working people, SFDs also faced with of information on the quantity and facilities management from the dietitian in the company. my research revealed that dietitian's teaching method for SFDs still remains in a very primitive way and accordingly the efficient way to solve these problems shall be established by a computerized education program through which dietitians can provide well-balanced meals for working people when they are assigned to the company. In this regard we must consider that we have to enact certain law to be applied to a dietitian. In another words we should emphasize actual experiences of SFDs' knowledge accumulated through the field training & practice before they work at the company. Consequently it is a time to reconsider the importance of well-balance dietitian program offering an opportunity for SFD which can contribute to improvement of health's condition for the working people.

The antifungal activity of isolated lactic acid bacteria (LAB) from a locally fermented cereal, "Kunu", was tested against toxigenic Aspergillus flavus. The liquid refreshment, "Kunu", was prepared under hygienic condition using millet, sorghum, and the combination of the two grains. The antifungal potential of isolated LAB against toxigenic A. flavus was carried out using both in vitro and in vivo antifungal assays. The LAB count from prepared "Kunu" ranged from $2.80{\times}10^4CFU/mL$ to $4.10{\times}10^4CFU/mL$ and Lactobacillus plantarum, Lactobacillus delbrueckii, Lactobacillus fermentum, Pediococcus acidilactici, and Leuconostoc mesenteroides were the isolated bacteria. Inhibitory zones exhibited by LAB against toxigenic A. flavus ranged from 5.0 mm to 20.0 mm. The albino mice infected with toxigenic A. flavus showed sluggishness, decrease in body weight, distortion of hair, and presence of blood in their stool, while those treated with LAB after infection were recovered and active like those in control groups. Except for the white blood cell that was increased in the infected mice as $6.73mm^3$, the packed cell volume, hemoglobin, and red blood cell in infected animals were significantly reduced (P<0.05) to 29.28%, 10.06%, and 4.28%, respectively, when compared to the treated mice with LAB and control groups. The antifungal activity of LAB against toxigenic A. flavus can be attributed to the antimicrobial metabolites. These metabolites can be extracted and used as biopreservatives in food products to substitute the use of chemical preservatives that is not appealing to consumers due to several side effects.
