Purpose: This study was conducted to assess the incidence and characteristics of pressure ulcer in relation to the type of equipment and supplies(EnS) in intensive care unit(ICU). Method: By using secondary data analysis and descriptive investigation, 29 patients of pressure ulcers caused by EnS were examined from January 2013 to December 2015, at the advanced general hospital located in Gyeongsangnam-do. The subjects were aged 19 years and above and had been in the ICU for more than 3 days. The data were analyzed using the SPSS WIN 23.0 with frequency, percentage, and mean and standard deviation. Result: The incidence of EnS-related pressure ulcers was 3.71%. The EnS-related causes for pressure ulcers were endotracheal tube(31.03%), restraint(20.69%), and neck brace(10.34%). The longest use of EnS was oxygen tube(29 days). EnS that were possibly causing pressure ulcer for one day were restraint(upper extremities), endotracheal tube(oral and face), and oxygen mask(ear and nose). Conclusion: This study has been limited to secondary data analysis that may result in missing records of pressure ulcers related to EnS in ICU. However, the analysis of this research is expected to contribute to the development of nursing interventions to clarify the guidelines for the prevention of pressure ulcers related to EnS in ICUs.

The components of Magnolia officinalis have well known to act anti-inflammatory, anti-oxidative and neuroprotective activities. These efficacies have been sold many products as nutritional supplement extracted from bark of Magnolia officinalis. Thus, to assess and compare neuroprotective effect in the nutritional supplement (Magnolia $Extract^{TM}$, Health Freedom Nutrition LLC, USA) and our ethanol extract of Magnolia officinalis (BioLand LTD, Korea), we investigated memorial improving and anti-Alzheimer's disease effects of extract products of Magnolia officinalis in a transgenic AD mice model. Oral pretreatment of two extract products of Magnolia officinalis (10 mg/kg/day in 0.05% ethanol) into drinking water for 3 months ameliorated memorial dysfunction and prevented $A{\beta}$ accumulation in the brain of Tg2576 mice. In addition, extract products of Magnolia officinalis also decreased expression of ${\beta}$-site APP cleaving enzyme 1 (BACE1), amyloid precursor protein (APP) and its product, C99. Although both two extract products of Magnolia officinalis could show preventive effect of memorial dysfunction and $A{\beta}$ accumulation, our ethanol extract of Magnolia officinalis (BioLand LTD, Korea) could be more effective than Magnolia $Extract^{TM}$ (Health Freedom Nutrition LLC, USA). Therefore, our results showed that extract products of Magnolia officinalis were effective for prevention and treatment of AD through memorial improving and anti-amyloidogenic effects via down-regulating ${\beta}$-secretase activity, and neuroprotective efficacy of Magnolia extracts could be differed by cultivating area and manufacturing methods.

The purpose of this study was to examine the association between the symptoms of temporomandibular joint disorders and lumbar diseases in adults when the prevalence rate of osteoarthritis is increasing and to help develop health policies that can improve oral health and health in general. The study used representative data from the 5th Korea National Health and Nutrition Examination Survey phase 3 (2012). In total, we analyzed the data of 3,017 individuals aged over 50 years who participated in the health-related survey and underwent radiography of the lumbar joints. PASW statistics ver. 18.0 was used for analysis. This study revealed the following results: 16.1% experienced at least one symptom of temporomandibular joint disorders within the recent single year, 20.6% experienced lower back pain in the recent three months, and 30.6% had lumbar osteoarthritis revealed using radiography of the lumbar joints. Symptoms of temporomandibular joint disorders, lower back pain, and lumbar osteoarthritis were correlated with each other; the respondents who experienced symptoms of temporomandibular joint disorders had 1.70 times (95% confidence interval [CI], 1.30~2.22) higher prevalence of lower back pain and 1.20 times (95% CI, 0.86~1.68) higher prevalence of lumbar osteoarthritis than in those with no such difficulties. The results of this study confirmed that the symptoms of temporomandibular joint disorders affected lumbar diseases in adulthood. Therefore, adequate treatment and prevention of the symptoms of temporomandibular joint disorders in adults is expected to make crucial contributions to decreases in the prevalence rate of lumbar diseases and an improvement in the quality of life.

This study was performed to determine the health and nutritional risk factors associated with hypertension in Koreans over the age of 50 in a high-income class (more than twice as much family income as the 2005 Korean minimum cost of living, 668,540 Won). A total of 505 subjects aged over 50 from the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) were divided into two groups: A hypertension group (HG) (N=151, Systolic Blood Pressure ${\geq}$140 mmHg or Diastolic Blood Pressure ${\geq}$90 mmHg) and normal group (NG) (N=354). Subjects who took hypertension medicines or underwent diet therapy were excluded. In HG, mean daily alcohol intake and the amount of alcohol consumption per one occasion were significantly higher than in NG, respectively. A greater number of hypertension subjects answered that they drank alcohol to reduce stress as compared to normal subjects. HG also took fewer dietary supplements than NG. Mean body mass index (BMI), waist circumference, fasting blood sugar level, and 2 hour postprandial blood sugar following a glucose load were significantly higher in HG than in NG, respectively. Also, iron, thiamin, and niacin intakes and the consumption frequency of seaweeds were significantly lower in HG than in NG, respectively. Finally, obesity (BMI ${\geq}$25 $kg/m^2$), abdominal obesity (waist circumference ${\geq}$90 cm for males, ${\geq}$ 80 cm for females), high blood sugar level 2 hours after an oral glucose load (${\geq}$140~200 mg/dl), and hypertriglyceridemia (serum TG ${\geq}$200 mg/dl) were related to a significantly higher risk of hypertension in the subjects (odds ratio: 1.884~3.040). In conclusion, dietary factors such as higher alcohol consumption; lower intakes of iron, thiamin, and niacin; lower consumption frequency of seaweeds; and metabolic syndrome were associated with hypertension in the study subjects.

The demand for medical care and welfare for patients with disabilities is expanding, and healthcare professionals are also increasingly interested in the need for medical care for patients with disabilities. The purpose of this study was to evaluate the competency of disabled patients' management and the education experience of dental hygiene students, who are the main players of oral health care for disabled patients. A total of 196 students in the dental hygiene department and 3rd and 4th grade students were surveyed using questionnaires. As a result, most of the students had a positive awareness of disabled patients; 84.7% answered with the need to train dental hygienists in specializing in handicapped patients, 76.5% were willing to attend seminars related to disabled patients after graduation, and 71.4% of the students provided dental treatment for patients with disabilities in curriculum and comparative curriculum. The students who provided treatment for disabled patients showed that their competence in most areas of knowledge of disabled patients, oral health education, and oral disease prevention was highly evaluated as significant. The competence of respondents who answered that the theoretical education was sufficient was significantly higher. Based on this, institutional support for the education of dentistry for disabled patients is needed, and sufficient theoretical education and practical training should be offered to foster personnel capable of contributing to the improvement in the oral health of patients with disabilities. In addition, in-depth discussions on the training of dental hygienists specialized in handicapped patients should be conducted.

Objectives: Fluoride is widely used in the prevention and control of dental caries. The purpose of this study is to examine the biological effects of Sodium fluoride on the proliferation of oral normal cell in vitro(MDPC-23, HaCaT, HGF-1 cells). Methods: The proliferation of normal cells and the cyto-skeletal change of normal cells were assessed by WST-1 assay and F-actin stain assay. The statistical significances of the resulting data were analyzed using SPSS(Window 12.0). Results: The sodium fluoride(0-12 mM) treatment decreased the cell viability in a dose and time dependent manner: HaCaT(6 h): $100{\pm}0$, $98{\pm}0.39$, $82{\pm}2.68$, $75{\pm}0.83$, $69{\pm}1$, $67{\pm}1.42%$(p<0.005); HaCaT(24 h): $100{\pm}0$, $98{\pm}1.85$, $54{\pm}0.64$, $43{\pm}0.4$, $38{\pm}0.32$, $36{\pm}0.13%$(p<0.006), MDPC-23(6 h): $100{\pm}0$, $93{\pm}1.48$, $85{\pm}0.28$, $82{\pm}1.58$, $79{\pm}1.48$, $76{\pm}1.93%$(p<0.009); MDPC-23(24 h): $100{\pm}0$, $91{\pm}1.26$, $58{\pm}0.65$, $49{\pm}1$, $44{\pm}0.74$, $2{\pm}0.05%$(p<0.005), HGF-1(6 h): $100{\pm}0$, $97{\pm}2.93$, $89{\pm}5$, $71{\pm}5.42$, $58{\pm}4.82$, $43{\pm}3.47%$(p<0.009); HGF-1(24 h): $100{\pm}0$, $97{\pm}2.05$, $73{\pm}1.73$, $22{\pm}1.61$, $14{\pm}1.73$, $7{\pm}0.85%$(p<0.005). Thus, changes in cell morphology and disruption of filamentous(F)-actin organization were observed in higher concentration. Conclusions: These results suggest that higher concentrations of fluoride lead to a reduce the number of cells and morphology change of normal cell.

The treatment and prevention of periodontitis is focused on the reduction and the elimination of pathogenic bacteria, especially A. actinomycetemcomitans and black pigmented bacteria such as P. gingivalis. To prevent recurrent disease, the recolonization of these bacteria should be inhibited in the periodontal pocket. Since the replacement therapy was introduced in periodontics by Hillman et al, Jeong et al reported that hydrogen peroxide-producing Lactobacillus acidophilus V-20 completely inhibited P. gingivalis and A. actino - mycetemcomitans in vitro and mouth gargling with Lactobacillus acidophilus V-20 in periodontitis patients during the maintenance phase improved clinical condition and reduced the No. of P. gingivalis and A. actinomycetemcomitans at 4 weeks of treatment. Prior to replacement therapy with bacteria, dynamics of microbial colonization should be considered. This study was performed to evaluate the change in the viable cell number of Lactobacilli and P. gingivalis after oral administration of L. acidophilus V-20. In periodontal health, gargling increased the No. of Lactobacilli in saliva, buccal mucosa, supragingival plaque from the first week, which maintained for 2-3 weeks after gargling stop, and then returned to the undetectable baseline level at the ninth week. In the periodontal pocket of moderate periodontitis patients, daily irrigation for 1 week and weekly irrigation for subsequent 3 weeks decreased the viable cell number of P. gingivalis during the period of irrigation and increased the number of Lactobacilli, which was maintained from the second to the seventh week. L. acidophilus V-20 was isolated for the first 2 weeks of oral administration, and the 3 different strains of Lactobacilli were isolated continuously for remaining period and identified as L. ali - mentarius, L. casei subspecies casei and L. fructosus. The first two Lactobacilli strains completely inhibited P. gingivalis in vitro and all the isolated Lactobacilli strains reduced the artificial plaque formation by 55-63%. These results showed that mouth gargling or pocket irrigation with L. acidophilus V-20 increased the No. of intraoral Lactobacilli and caused to decrease in the No. of P. gingivalis. This suggests that the replacement therapy by these Lactobacilli might be useful in the maintenance care of periodontal patients.

Objectives: Water constitutes a majority of the human body and is essential for health. In addition, water intake can prevent dental caries by improving salivary lubrication and self-cleaning. This study aimed to determine the relationship between the amount of daily water intake and the symptoms of oral disease in Korean adolescents. Methods: We used data from the Korea Youth Risk Behavior Web-based Survey (KYRBS), conducted in Korea in 2021, and identified the relationship between daily water intake and oral disease symptoms in Korean adolescents. KYRBS is a nationwide cross-sectional survey conducted by the Korea Disease Control and Prevention Agency (KDCA), and a total of 54,848 participants were included in this study. Results: After adjusting for confounding factors, logistic regression analysis showed that tooth pain was more often experienced by those who drank less than two cups of water per day (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.01-1.30) than those who drank five or more cups of water per day. Conclusions: A low daily water intake is associated with tooth pain, a symptom of dental caries. The results of our study suggest that increasing water intake may reduce dental caries. Therefore, adequate water intake may help prevent dental caries.

In order to develop the program of oral hygiene education for elementary school senior-students, a questionnaire survey of elementary fourth, fifth and sixth students who are under continual control program of oral hygiene. (1) For tooth brushing time, after dinner is more than before. 73.7% of respondents brushed the teeth twice or more a day. (2) 62.1% of respondents took the cariogenic food twice or more a day. (3) 90.1% of respondents had visited a dental clinic. (4) Concerning fear for dental treatment, only 14.4% had a feeling of fear. (5) Regarding the experience with a preventive treatment, 39.7% had an experience with pit and fissure sealing, and 24.2% had an experience with the application of fluorides. (6) 46.2% of respondents had a preference for the fluoride mouth rinsing program, and 38.4% wanted that program to keep going on. As to the reason to favor the fluoride mouth rinsing program, 38.2% preferred it because of prevention of dental caries, and 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do. (7) Comparing with the research result in 2000, we proved positively the educational effect of brushing frequency, positive understanding and preference to water school fluoridation program, and got the negative data of experience of visiting to oral clinic and preventive treatment.
