Purpose: Mandibular advancement device (MAD) is widely recognized as an important treatment option for obstructive sleep apnea (OSA) and is readily accepted than any other treatment options owing to its simplicity and ambulatory nature. At this time, there are a multitude of MAD designs and their efficacies may be influenced by adjustment and retention mechanism. The MAD with the anterior connector (anteriorly adjustable mandibular advancement device, AAMAD) was newly developed in the Department of Oral Medicine, Dankook University Dental Hospital (Cheonan, Korea) and was prescribed for the OSA patients including snoring patients. Thus, this study was aimed to objectively investigate the effectiveness of the AAMAD on the OSA patients using the self-applied portable device (ApneaLink), and evaluate the treatment outcomes among patients with various severity of OSA level. Methods: Results of the treatment of fourteen patients (13 male, 1 female) with the AAMAD were retrospectively analyzed. Each patient underwent home sleep test before treatment and were divided into two groups, i.e., those with mild (apnea-hypopnea index [AHI] ${\geq}5$ and <15) to moderate OSA (AHI ${\geq}15$ and <30) and severe OSA (AHI ${\geq}30$). After treatment, home sleep test was conducted again and treatment outcomes were compared between mild to moderate and severe OSA patients. Results: Of all patients, 78.6% showed more than 50% AHI reduction. We found a significant reduction (85.3%) of AHI in the severe OSA patients. Patients with mild to moderate OSA showed the reduced AHI (56.1%). Conclusions: We concluded that AAMAD is an effective oral appliance for the majority of OSA patients.

Purpose: The purpose of this study is to examine the status of care-giving for the demented elderly and to find out the need of community in-house care services-day care services, short-term care services, home help services, and home care services. Method: It analyzed the data of 186 old people having dementia, and caregivers. Data were collected for five days, in September 2002. Results: The caregivers were mostly women and the burden for the care giving was high (87.5%). They used community care services, that is, day care services (26.5%), home care services (21.6%), home help services 00.8%), short-term care services (6.2%). Caregivers' age and education level were significant factors in the demand for day care services. Caregivers' education level was a statistically significant factor in the demand for short-term care services and home help services. Caregivers' age and education level were significant factors in the demand for home care services. Conclusions: It is necessary to expand the financial aid for the active implementation of daytime protection for dementia-patients under medical treatment at home and to promote patients' recovery. It is necessary to enhance home help services and home care services, and to establish many day care centers and short term care centers. Through this, it will prevent caregivers from becoming burnt out due to the burden of care giving.

The storage stability of the developed Formula of infant foods was investigated. The results are summarized as follows : When formula A and B were stored at room temperature and refrigeration temperature, there was no remarkable changes in consistency. In frozen state, formula A showed more stability in consistency than formula B and formula A could be stored for 6 months without problems due to retrogradation of starch. The heat treatment of both A and B resulted in the increase of a-value, while L-and b-value showed no such change. But from the 4th month at room temperature, and 5th to 6th month at refrigeration appeared an increase in a -value, hence the browning reaction, while frozen samples did not show noticeable changes in surface color. The heat treatment also caused an increase in POV on both formula. The extent of changes in POV during storage varied with storage temperatures and samples.

The dyeing characteristics of Dylon hand dyes on the cotton & silk fabric were studied, and the fastnesses of Dylon hand dyes were compared with those of direct & acid dyes. The results are as follows. 1. Dye adsorption of Dylon hand dyes increased as the concentration of dye increased. 2. Dye adsorption was increased as treatment time increased, and reached to eqilibrium after forty minutes treatment. 3. The temperature at mixiumum adsorption was 6$0^{\circ}C$, in the range of lower temperature than 6$0^{\circ}C$ color was changed, in the range of higher temperature adsorption of dye was decreased. 4. Dye adsorption was increased in direct proprotion to NaCl concentration and reached to equilibrium. But NaCl concentration of even and maximum adsorption was 5%. 5. Wash fastness of Dylon hand dyes was better than direct & acid dyes, but light fastness was worse.

The purpose of this clinical trial was to study the effectiveness of 5% potassium nitrate dentifrice as a daily home treatment of dentinal hypersensitivity. Thirty subjects with dentinal hypersensitivity were included in a 4-week, double-blind, parallel, comparative study. Stimuli used included mechanical, cold water and compressed air blasts. A subjective assessment of the degree of hypersensitivity for each stimulus was recorded. The results indicated that 5% potassium nitrate dentifrice, in comparision with a conventional fluoride dentifrice, reduced dentinal hypersensitivity to a significant degree. The therapeutic response to potassium nitrate was apparent within 2 weeks and increased continuously for the length of the study period. We conclude that 5% potassium nitrate dentifrice is an effective agent for the daily home treatment of dentinal hypersensitivity.

The softening of the femented vegetables and the fruits was resulted from the degradation of pectin substances, cellulose, hemicellulose by polygalacturonase(PG), pectinesterase(PE), Cx-cellulase, $\beta$-galctosidase. The conversion of insoluble pectin to soluble pectin in cell wall-middle lamella was a major factor in the changes of firmness. Ca2+ was substantially increased firmness. However, Ca2+ could be removed from cell wall by chelating agents such as oxalic acid and citric acid. And Ca2+ was replaced with Na+ by ion exchange reaction. Ca2+ deficient tissue was vulnerable to attack by PG. Preheating treatment and Ca2+ addition is most effective in inhibiting the vegetable food softening and in increasing middle lamella-cell wall regidity, which PE activation by preheating treatment and Ca2+ addition could created more anionic carboxyl groups for cationic materials binding such as Ca2+ and chitosan and for polypectategel formation. Excessive demethylation by PE was associated with loosening of middle lamella cell wall components and softening.

The purposes of this study were to a develop a preventive tailored early intervention program and to investigate the effects of the program on the quality of parenting for low income families. The subjects were eighty five infants, aged 13 to 32 months, and their mothers. Of the 85 mother-infant dyads, 42 dyads were randomly assigned to the experimental group and 43 dyads to the control group. To prevent the risks of the adverse development of infants from low income families a tailored intervention program was created based upon the transactional model. This emphasized the quality of the home environment and of the daily mother-infant interaction. The risk factors were assessed and progress monitoring was undertaken for the preventive tailored intervention treatment. In order to assess the effects of the program, HOME, the NCAST Teaching Scale and the Parenting Stress Index/Short From were used. The collected data were analyzed with descriptive statistics, ANCOVA, and the McNemar test. The experimental group showed a significant increase in performance and higher scores than the control group on the scores from HOME, and the NCAST Teaching Scale and significant decrease and lower scores in the Parenting Stress Index(SF).
