The purpose of this study was to evaluate the status of oral health care in dementia patients living in long-term care facilities and to investigate the effects of this on swallowing function and swallowing-quality of life. The subjects were 60 demented patients who were admitted to long-term care facilities in Gwangju and Jeonnam provinces. Their Oral Health Assessment Tool(OHAT), Clinical Dysphagia Scale(CDS), and Oral Health Impact Profile 14(OHIP-14) were measured. The results of this study were as follows: First, the effect of oral health care on dentition patients using long-term care facilities on swallowing function and swallowing-quality of life was significantly different according to oral care score (p<.05)(p<.01). Second, the relationship between oral health care and swallowing function of dementia patients and swallowing-quality of life. was examined. As a result, oral health care of dementia patients was affected by swallowing function (r=.405, p<.01) the swallowing-quality of life (r=.462, p<.01) and swallowing function were significantly correlated with swallowing-quality of life (r=.351, p<.01). Therefore, the oral health care of users of long-term care facilities was closely related to swallowing function and swallowing-quality of life.

Arbuscular mycorrhizal fungi (AMF) are ubiquitous in the rhizosphere and form symbiotic relationships with most terrestrial plant roots. In this study, four strains of Rhizophagus clarus were cultured and variations in their growth characteristics owing to functional diversity and resultant effects on host plant were investigated. Growth characteristics of the studied R. clarus strains varied significantly, suggesting that AMF retain high genetic variability at the intraspecies level despite asexual lineage. Furthermore, host plant growth response to the R. clarus strains showed that genetic variability in AMF could cause significant differences in the growth of the host plant, which prefers particular genetic types of fungal strains. These results suggest that the intraspecific genetic diversity of AMF could be result of similar selective pressure and may be expressed at a functional level.

I analyzed the relationships among motives, strategies, and performances of the university-initiated R&D activities in the Information Technology Research Center(ITRC) Projects. I suggested a research model and 3 hypothesis about them through analysis of a lot of literatures. And I also made an empirical test on the hypothesis through statistical methods. The data which were used in this analysis were gathered through a questionnaire survey to the head of R&D projects in the ITRCs. I would make several useful suggestions to the head of university's ITRCs and the policy makers. Firstly, the type of university's R&D strategy were influenced from several motives such as technology development and acquisition, co-utilizations of research facilities, and utilization and rearing of the expertise. Secondly, to select an optimal type of R&D strategy, the university should considered the efficient methods which were related to forecasting market size of new product and new technology, and to using the useful information on technology development, and to securing the expertise. Thirdly, the researcher and manager of ITRCs had to recognize the correct forecast of future market size of new product and new technology and a useful information about technology development, as the most important factors in improving performances of R&D projects. Lastly, They had to make an effort of getting the efficient methods to secure the expertise, research facilities, and rational compensation system.

The objective of this study was to optimize medium composition of initial pH, tryptone, glucose, yeast extract, and mineral mixture for production of bacteriocin by Lactobacillus acidophilus ATCC 4356, using response surface methodology. A response surface approach including new statistical and plotting methods was employed for design and analysis of the experiment. An interiorly augmented central composite design was used as an experimental design. A normal-distribution log-link generalized linear model based on a subset fourth-order polynomial ($R^2$=0.94, Mean Error Deviance=0.0065) was used as an analysis model. This model was statistically superior to the full second-order polynomial-based generalized linear model ($R^2$=0.80, Mean Error Deviance=0.0140). Nonlinear programming determined the optimum composition of the medium as initial pH 6.35, typtone $1.21\%$, glucose $0.9\%$, yeast extract $0.65\%$, and mineral mixture $1.17\%$. A validation experiment confirmed that the optimized medium was comparable to the MRS medium in bacteriocin production, having the advantage of economy and practicality.

This research is a descriptive correlation research for comprehending the end of life care stresses, work environment, and reduction of nurses in geriatric hospitals and analyzing the factors influencing their burnout. We recruited 195 nurses from 8 geriatric hospitals in B metropolitan city and collected data on the end of life care stress, work environment and reduction using organized questionnaires. The data were analyzed with SPSS WIN 21.0 program. The average grade of end life care stress was $3.84{\pm}0.56$, nursing work environment $3.25{\pm}0.60$, and burnout $2.93{\pm}0.52$. There was a positive correlation between the end of life care stress and reduction(r=.206, p=.004) but a negative correlation between nursing work environment and reduction(r=-.431, p<.001). The most influential factor on the reduction was nursing satisfaction(${\beta}=-.302$), followed by work environment(${\beta}=-.294$), age(${\beta}=.286$), duty style(${\beta}=-.17$), and end of life care stress(${\beta}=.164$). The overall explanatory power was 41.2%.These results suggest that in order to minimize the reduction of nurses in geriatric hospitals, the provision of a supportive work environment which enhances their pride and responsibility as a nurse and offers incentives is required with effective distribution of duties, development of the end of life nursing education and administrative tools for reducing their stress.

The purpose of this descriptive research study was to investigate health beliefs and self-efficacy in respiratory infection management as factors that affect the respiratory infection prevention behavior of college students. The subjects were 178 students attending a university in K city of Gyeongsangbuk-do. Data were collected with a structured questionnaire from September 1st to October 16th of 2020. The results of this study are as follows; Health belief was significantly different from participant's gender (t=-2.86, p=.005), major classification (F=2.95, p=.034), and taking any medications (t=2.18, p=.030). Self-efficacy in respiratory infection management was significantly different from university students' gender (t=-3.56, p=<.001) and major classification (F=4.59, p=.004). Health belief (r=.276, p<.001) and self-efficacy in respiratory infection management (r=.660, p<.001) had a positive correlation with respiratory infection preventive behavior. Multiple regression analysis results show that self-efficacy in respiratory infection management (β=.66, p<.001) significantly affected respiratory infection preventive behavior. The model had an explanatory power of 43%. The findings demonstrate that the major factor influencing the respiratory infection preventive behavior of university students is self-efficacy in respiratory infection management. Therefore, in order to promote behavior to prevent respiratory infection in college students, a program that can strengthen self-efficacy in respiratory infection management should be developed.

This study examined two differences in physical and psychological recovery patterns after surgery in the elderly. The sample consisted of 40 patients with abdominal surgery In five large hospitals in Seoul. The data for this study were collected from Apr. 20 to Nov. 26 by structured questionnaire, chart review and call. Physical recovery was assessed by ADL, a Cantril Ladder Scale and a Visual Analogue Scale. Psychological recovery was measured by the Geriatric depression Scale and a Cantril Ladder Scale. The data were analyzed using frequency, percentage, Pearson Correlation Coefficient, and MANOVA by SPSS/WIN. The result are as follows : 1. Physical recovery indicated significant improvement over time with the exception of ADL(F=.812 p=.449). Perceived physical health were significantly improved(F=6.189 p=.004). Pain & discomfort was significantly decreased(F=3.927 p=.025). 2. Perceived psychological health was significantly improved over time(F=20.648 p=.000), but depression showed no statistical significance improvement over time(F=1.393 p=.256). 3. There were no significant effects of sex, age, complication and combined chronic diseases on physical and psychological recovery patterns. 4. There were significant correlations between operation time and pain(r=-.331 p=.020), recovery time and perceived psychological health(r=-.320 p=.024), recovery time and pain(r=.404 p=.005). There were significant correlations between admision period and ADL(r=-.418 p=.004), perceived physical health(r=-.354 p=.014), depression(r=.280 p=.042), and perceived psychological health(r=-.447 p=.002). BRAS showed significant correlation with ADL(r=-.458 p=.002). 5. With an increase in the degree of perceived health(physical and psychological), ADL was significantly increased. With an increased in the degree of depression and pain, ADL and perceived health(physical and psychological) were significantly decreased. In conclusion, the elderly patient recovered significantly over time with the exception of ADL and depression. It these we suggested to considered when planning care for elderly patients.

Purpose: The study was conducted to identify factors affecting the intraoperative core body temperature (CBT) of surgical patients under general anesthesia. Methods: This study was performed through a prospective descriptive research design. The sample consisted of 138 patients who had undergone elective laparotomy surgery. Age, weight, height, the basal preoperative CBT, blood pressure, and heart rate were collected. CBT was again measured at induction of anesthesia, 1 hour, 2 hours, and 3 hours following induction of general anesthesia. Results: Factors affecting intraoperative hypothermia < $36^{\circ}C$ at 1 hour following induction, were CBT at induction and total body fat (TBF) ($R^2=.569$, p<.001); at 2 hours after induction, CBT at induction and TBF ($R^2=.507$, p<.001); at 3 hours after induction, CBT at induction (${\beta}=0.34$), TBF, age and the ambient temperature in the operating room ($R^2=.449$, p<.001). Conclusion: CBT at induction and TBF appear to be factors affecting intraoperative CBT within 2 hours after induction of anesthesia; CBT at induction, TBF, advanced age and the ambient temperature after 3 hours following induction. We recommend keeping surgical patients warm before induction of anesthesia and providing intraoperative warming for surgical patients of advanced age with low TBF and when the duration of general anesthesia will last more than 3 hours.

Purpose: This study was done to examine factors influencing loneliness in the elderly living in nursing homes. Method: The participants for this study were 150 adults, age 60 or over who had lived for one year or longer in two nursing homes in Gwangju. The questionnaires consisted of measurements of activities of daily living (ADL), social support and loneliness. Frequencies, percentages and means were used with Pearson correlation coefficients, t-test, ANOVA, and Scheffe test to analyze the data. The analysis was done with SPSS 12.0 Stepwise multiple regression was used to identify significant factors influencing loneliness in the elderly living in nursing homes. Results: Significant correlations were found between level of ADL and loneliness (r=-0.379, p<.001), support from friends and loneliness (r=-0.472, p<.001), and support from significant others and loneliness (r=-0.449, p<.001). Loneliness was significantly influenced by support from friends, ADL, and support from significant others. This regression model explained 29% of the variances in loneliness. Conclusion: The findings in this study suggest that improvement in support from friends and ADL can lead to a reduction in loneliness in the elderly living in nursing homes.
