Purpose: This in vitro study was performed to assess the adherence of Porphyromonas gingivalis to a resorbable blast media (RBM) titanium surface pretreated with an ultrasonic scaler or toothbrush and to evaluate the effects of the treatment of the RBM titanium discs on the bacterial removal efficiency of brushing by crystal violet assay and scanning electron microscopy. Methods: RBM titanium discs were pretreated with one of several ultrasonic scaler tips or cleaned with a toothbrush. Then the titanium discs were incubated with P. gingivalis and the quantity of adherent bacteria was compared. The disc surfaces incubated with bacteria were brushed with a toothbrush with dentifrice. Bacteria remaining on the disc surfaces were quantified. Results: A change in morphology of the surface of the RBM titanium discs after different treatments was noted. There were no significant differences in the adherence of bacteria on the pretreated discs according to the treatment modality. Pretreatment with various instruments did not produce significant differences in the bacterial removal efficiency of brushing with dentifrice. Conclusions: Within the limits of this study, various types of mechanical instrumentation were shown to cause mechanical changes on the RBM titanium surface but did not show a significant influence on the adherence of bacteria and removal efficiency of brushing.

Purpose: The purpose of this study was to evaluate the psychometric properties of the Hypertension Self-Care Behavior Scale for older adults with hypertension in Korea. Methods: A cross-sectional descriptive study was used with 196 participants. Translation and back-translation were performed by bilingual nursing professionals and a nutritionist. Reliability and validity such as content validity, construct validity, and concurrent validity were conducted. To evaluate the concurrent validity, the correlation coefficients between the Korean version of Hypertension Self-Care Behavior and concurrent scales (hypertension adherence scale and self-efficacy scale) were calculated. Results: The total 20 items for the Korean version of the Hypertension Self-Care (HBP-SC) Behavior Scale were retained during item-analysis. In explanatory factor analysis, a two-factor solution was proposed and the two factors named, 'HBP-SC Diet behavior' and 'HBP-SC Health behavior (except diet)'. The two factors accounted for 48.9% of the variances. The Korean version of the Hypertension Self-Care Behavior Scale correlated with concurrent variables such as hypertension adherence and self-efficacy. For reliability of the Korean version of the Hypertension Self-Care Behavior, Cronbach's ${\alpha}=.92$. Conclusion: Findings show that the Korean version of the Hypertension Self-Care Behavior is reliable and valid for measuring self-care behavior of older adults with hypertension.

시판되는 보리차 3종(티백형 2종 알곡형 1종)이 우식유발 세균인 Streptococcus mutans와Streptococcus sobrinus가 타액피복 수산화인회석에 부착되는 정도와 이들 세균의 체표소수성에 미치는 영향에 대해 평가하였다. 모든 실험군에서 보리차로 처리하였을 때 수산화인회석에의 부착능과 세균의 체표소수성은 감소하였고 이 값은 보리차의 종류와 처리방법에 따라 상이하였다. 이러한 결과는 보리차에 함유된 활성성분인 catechins와 melanoidins의 영향 때문인 것으로 추측되며 보리차로 전 처리한 수산화인회석에 세균이 부착하는 정도가 감소한 것은 활성물질이 흡착되어 치아표면의 수용체가 세균의 부착소와 작용하는 것을 방해함으로써 치아우식증 병인론의 초기 단계인 부착에 영향을 미칠 수 있다는 것을 의미한다. 본 연구결과 보리차가 우식유발 세균의 주요 독력인자 중 하나인 부착능을 억제하므로 보리차가 이러한 세균이 일으키는 치아우식증을 억제할 수도 있다는 가능성을 보여준다.

Purpose : Colonization of denture soft lining materials by Candida albicans can result in clinical problem, and deterioration of the materials. This study aimed to compare the retention and penetration of C. albicans into four denture soft lining materials commonly used. Materials and methods : Four denture soft lining materials (Coe-comfort$^{(R)}$, Coe-soft$^{(R)}$, GC soft liner$^{(R)}$, and Tissue conditioner$^{(R)}$) discs were prepared to glass slide and dental stone. Adherence of yeast to surfaces was monitored after one hour incubation of standardized washed cell suspension with test disc surfaces. Adherent cells stained with acridine orange were counted fluorescence microscopy. Penetration of yeast into materials bonded with acrylic resin after 1, 2, 3,4, 5, 6 and 7 days incubation was observed through sections stained using acridine orange and estimated to quantitative analysis using radioisotope. Results : There was statistical significance in cell numbers between smooth and rough surfaces(p<0.05). Higher numbers of cells were observed on rough surfaces. There was statistical significance in adherent cell numbers into smooth and rough surfaces individually(p<0.05). According to the increase of incubation periods, the cells penetrated into denture soft lining materials were shown to increase. The differences among all kinds of soft liner were statistically significant(p<0.05),and the largest number of cells penetrated into soft liners was observed in the Coe-soft$^{(R)}$. Conclusion : Initial adherence and penetration of yeast into denture soft lining materials has been influenced by surface roughness and chemical composition of them. The selection of appropriate materials and their fabrication may promote clinical performance.

The prevalence of thermophilic Campylobacter (C.) spp. in stray, breeding, and household dogs was 25.2, 12.0, and 8.8%, respectively. C. jejuni and C. upsaliensis were the predominant Campylobacter spp. from household dogs. cdtA, cdtB, and cdtC were detected by PCR in all isolates. Despite the high cytolethal distending toxin (CDT) gene prevalence, only 26 (31%) C. jejuni strains and one (15.3%) C. coli strain showed evidence of CDT production in HEp-2 cell cytotoxicity assays. Virulence-associated genes detected in the C. jejuni and C. coli isolates were cadF, dnaJ, flaA, racR, ciaB, iamA, pldA, virB11, ceuE, and docC. cadF, dnaJ, flaA, and ceuE were found in all C. jejuni and C. coli isolates. When detecting Guillain-Barr$\acute{e}$ syndrome-associated genes (galE, cgtB, and wlaN), galE was identified in all isolates. However, cgtB and wlaN were more prevalent in C. jejuni isolates from humans than those from dogs. Adherence and invasion abilities of the C. jejuni and C. coli strains were tested in INT-407 cells. A considerable correlation (adjusted $R^2$= 0.678) existed between adherence and invasion activities of the Campylobacter spp. isolates.

Purpose: The purpose of this study was to develop a heart health diary to promote self-care ability among patients with heart failure (HF), and to identify the diary's effect on self-care adherence, self-efficacy, and physical activity. Methods: A randomized control-group pretest-posttest design was adopted using block randomization. A calender-typed health diary was developed and it included a self-care checklist and education information on HF management. The experimental group were given guided counseling and education for 8 weeks and wrote a daily health diary during that period. Data were collected from the outpatient department of a tertiary medical center from February to April 2016. To verify the hypotheses, data for the experimental group (n=28) and control group (n=33) were analysed using the independent t-test with SPSS/WIN 21.0. Results: At the end of 8 weeks the experimental group had significantly higher scores for self-care adherence (t=-2.48, p =.016) and exercise related self-efficacy (t=-3.44, p =.001) compared to the control group. Conclusion: The findings show that the application of a patient-directed heart health diary is an effective nursing intervention for improving HF patients' self-care adherence and exercise self-efficacy. Strategies to promote dietary self-efficacy are necessary along with further studies including repeated research with an increasing intervention period. Healthcare providers need to encourage the utilization of a health diary for HF patients as a tool for evaluation and for implementation that leads to self-care.

Purpose: This study was conducted to identify the effects of education regarding action plans according to a self-monitoring program on self-management adherence, knowledge, symptom control, and health-related quality of life (HRQoL) among adults with asthma. Methods: Thirty-four patients were randomly assigned to the intervention group and thirty-two to the control group in this study. A tailored 50-minute intervention based on the contents of self-monitoring and action plans developed by the National Heart Lung and Blood Institute was provided to the intervention group. Structured and well developed questionnaires were used to measure the dependent variables. Results: There were no differences in all general and clinical characteristics, and the dependent variables between two groups in the pre-test. In the post-test, there were differences in the level of self-management adherence (t=4.41, p<.001), knowledge (t=2.26, p=.027), symptom control (t=-2.56, p=.013), and total HRQoL (t=2.14, p=.036) between the two groups, although there was a difference only in the sub-domain of emotion (t=2.03, p=.047) in HRQoL. Conclusion: This study found that action plans according to self-monitoring that enhance a participatory interaction in the treatment and care could help patients with moderate to severe asthma to engagead equately in self-care, to control their symptoms, and to improve their HRQoL. Further studies are still needed to identify longitudinal effects of this program.

Purpose : The purpose of this study was to analyze factors influencing the adherence to guidelines for intensive care unit (ICU) nurses to control infections due to multidrug-resistant organisms (MDRO). Method : Participants were 194 ICU nurses at 3 university hospitals. Questions for the survey inquired about attitude, subjective norms, perception of patient safety culture to carry out MDRO management guidelines, perceived behavior control (PBC), and intention, based on the theory of planned behavior. Path analysis were utilized. Results : The path analysis presented that PBC, perception of patient safety culture, and intent had a direct effect on MDRO management guidelines. Attitude towards following the manual did not have any correlation. The hypothetical model based on the theory of planned behavior was revealed as applicable; the degree of the variance in explaining adherence to the manual was 23 %, and the variance in explaining intention to fulfill the manual was 33 %. Conclusion : The results of this study suggest that we should develop a program to improve PBC to increase adherence to MDRO management guidelines. ICU nurses' perceptions of patient safety culture should also be surveyed.
