Objectives : The purpose of the study is to improve autonomous decision-making ability by analyzing the relationship between autonomy and decision-making ability. Methods : The subjects were 176 dental hygienists in Busan. Self-reported questionnaire was fill out from May 2012 to January 2013. Results : The average of the degree of autonomy was $2.20{\pm}0.29$. Buddhists showed the highest score of $2.37{\pm}0.37$ (p<0.05). Buddhists had the higher education than other religions (p<.05). Clinical decision-making ability was $2.21{\pm}0.25$. Among the subcategories, statistically significant differences (p<.05) was shown by gender, degree of education, and religion in the domain of "Exploration of Choice and Alternatives"; Buddhists showed a higher score in the domains of "Assessment and Re-evaluation of Decisions" and "Review of Values and Goals," with significant difference of p<.05. Autonomy and clinical decision making revealed a positive correlation in the categories "Assessment and Re-evaluation of Decisions" (r=.518, p=.000), "Review of Values and Goals" (r=.610, p=.000), and "Investigation of Information and Synchronization of New Information" (r=.314, p=.000). Conclusions : To improve the performance of dental hygienists, working systems and training will be intensified to develop the autonomy and clinical decision making.

Theophylline and $\beta$-adrenergic agonists are frequently used together in patients with respiratory diseases. However the clinical impact of $\beta_2$-adrenergic agonists on the blood concentration of theophylline is not fully evaluated. Formoterol, a newly available oral ${\beta}_2$-adrenergic agonist is frequently used in pediatric respiratory patients. The objective of this study was to investigate the effect of oral formoterol on theophylline's blood concentration. Randomized prospective study was conducted. Twenty-four children were enrolled on the study. Their age ranged 2 to 73 months (mean 35.8 months). Theophylline group (12 patients) received 10 mg/kg/day of for theophylline orally. Theophylline/formoterol group (12 patients) received 10 mg/kg/day of theophylline and $4\;{\mu}g/kg/day$ of formoterol orally. All medications were administered at least for 5 days starting on admission day. Theophylline's trough concentrations were obtained on days 3 and day 5. Pulse rates were recorded before the study medications were given on admission, and days 3 and day 5. Statistical significance was calculated by two-tailed Student's t-test. Theophylline's levels in children given theophylline and formoterol together were lower an those given theophylline alone ($6.38\pm0.90\;{\mu}g/ml\;vs\;7.43\pm0.77\;{\mu}g/ml$ on day 3(p<0.05), $5.62\pm0.56\;{\mu}g/ml\;vs.\;6.78\pm0.61\;{\mu}g/ml$ on day 5 (p<0.05)). In both groups, theophylline's trough concentration on day 5 were lower than day 3. There was no significant side effects in both groups. In conclusion, the new ${\beta}_2$ selective adrenergic agonist formoterol reduced serum theophylline levels in children with respiratory diseases. Further investigation is needed to clarify the long term effect of this drug interaction.

Histological studies indicate a tetracycline HCl similar to citric acid to induce connetive tissue repair in animals. When tetracycline HCl was used as a root conditioning agent in humans, there was a trend toward more connective tissue attachment than in root planing alone. The purpose of this study was to evaluate clinical effect of tetracycline HCl in the treatment of gingival recession. 44 teeth in 12 patients with bilaterally gingival recession & Miller classification I, II gingival recession were selected and 22 teeth were treated with 125mg/ml tetracycline HCl , the others was not treated with tetracycline HCl. Gingival recession, pocket depth, clinical attachment level, width of keratinized gingiva were observed at baseline, postoperative 4, 12, 20weeks. Both groups were statistically analyzed by Wilcoxon signed Ranks Test & Wilcoxon's rank sum test(Mann-whitney test) using SPSS program.(5% significance level) The results were as follows: 1........The change of gingival recession, clinical attachment level, keratinized gingiva in both groups were increased significantly at 4, 12, 20 weeks. 2.......The pocket depth exhibited no marked changes throughout the entire investigation in both groups. 3........The change of gingival recession in tetracycline group was increased significantly than control group at 4, 12, 20 weeks and the percentage of root coverage was 93% in tetracycline group and 83% in control group. 4........The change of clinical attachment level, pocket depth, keratinized tissue from baseline to 4, 12, 20 weeks was not differ significanltly in both group.

Sequencing depth, which is directly related to the cost and time required for the generation, processing, and maintenance of next-generation sequencing data, is an important factor in the practical utilization of such data in clinical fields. Unfortunately, identifying an exome sequencing depth adequate for clinical use is a challenge that has not been addressed extensively. Here, we investigate the effect of exome sequencing depth on the discovery of sequence variants for clinical use. Toward this, we sequenced ten germ-line blood samples from breast cancer patients on the Illumina platform GAII(x) at a high depth of ${\sim}200{\times}$. We observed that most function-related diverse variants in the human exonic regions could be detected at a sequencing depth of $120{\times}$. Furthermore, investigation using a diagnostic gene set showed that the number of clinical variants identified using exome sequencing reached a plateau at an average sequencing depth of about $120{\times}$. Moreover, the phenomena were consistent across the breast cancer samples.

Background: Chlamydophila felis, formerly known as Chlamydia psittaci var. felis, is frequently associated with ocular, respiratory, and occasionally reproduction tract infections. Even though the infection is sometimes asymptomatic, it potentially results in a latent immunosuppressive infection. Objective: This study aimed to identify occurrences of feline chlamydophilosis, rarely reported in cats in Indonesia. Methods: The observation was conducted in three cats with clinical signs of Cp. felis infection, particularly relapsing conjunctivitis. The cats' histories were recorded based on owners' information. Conjunctival swabs were sampled for cytology examination and molecular assay detection. A phylogenetic tree was generated using MEGA-X software to reveal group clustering. A post-mortem examination was performed on the cat that died during an examination. Results: Cp. felis was detected in both cytological examination and polymerase chain reaction assay. The phylogenetic tree demonstrated that the Cp. felis isolated in this study clustered with several other isolates from the other countries. Cp. felis can be isolated from cats with different clinical manifestations and levels of severity. The chronic fatal infection demonstrated interstitial broncho-pneumonia under histopathological examination. Conclusions: Molecular assay of Cp. felis is always recommended to obtain a definitive diagnosis of feline chlamydophilosis since the disease can have various clinical manifestations. Even though it may be subclinical and is often not fatal, an infected cat may be a carrier that could spread the pathogen in the surrounding environment. Serious disease management is suggested to avoid high costs associated with regularly relapsing disease.

Objective: As clinicians and patients await consensus on intraovarian platelet-rich plasma (PRP) treatment, this project evaluated contemporary research trends in the literature. Methods: A PubMed/NLM search aggregated all ovarian PRP-related publications (n=54) to evaluate their scope, abstract utility, submission-to-publication interval, journal selected, article processing charge (APC), free reader access to full-text manuscripts, number and nationality of authors, and inclusion of international collaborators. The NIH Clinical Trials database was also audited. Results: Published output on intraovarian PRP has increased consistently since 2016, especially among investigators in Greece, Iran, USA, and Turkey. Between 2013 and 2021, 42 articles met the relevancy criteria, of which 40.5% reported clinical studies, small series, or case reports, 33% described experimental animal models, and 23.8% were opinion/review papers. Only two works included a placebo control group. The submission-to-publication interval (mean±standard deviation) was 130±96 days, there were 5.9±3.2 authors per project, and journals invoiced US $1,613±1,466 (range, $0-$3,860) for APCs. Conclusion: There was no correlation between APC and time to publish (Pearson's r=-0.01). Abstract content was inconsistent; sample size and patient age were often missing, yet free full-text "open access" was available for most publications (59.5%). The NIH Clinical Trials portal lists eight registered studies on "ovarian rejuvenation," of which two are actively recruiting patients, while four have been terminated or have an uncertain status. Two studies have concluded, with results from one posted to the NIH website. PRP and its derivatives for ovarian treatment show early promise, but require further investigation. Research is accelerating and should be encouraged, particularly placebo-controlled randomized clinical trials.

Objective This study evaluated the psychometric properties of the Korean Anxiety Screening Assessment (K-ANX) developed for screening anxiety disorders. Methods Data from 613 participants were analyzed. The K-ANX was evaluated for reliability using Cronbach's alpha, item-total correlation, and test information curve, and for validity using focus group interviews, factor analysis, correlational analysis, and item characteristics based on item response theory (IRT). The diagnostic sensitivity and specificity of the K-ANX were compared with those of the Beck Anxiety Inventory (BAI) and Generalized Anxiety Disorder 7-item scale (GAD-7). Results The K-ANX showed excellent internal consistency (${\alpha}=0.97$) and item-total coefficients (0.92-0.97), and a one-factor structure was suggested. All items were highly correlated with the total scores of the BAI, GAD-7, and Penn State Worry Questionnaire. IRT analysis indicated the K-ANX was most informative as a screening tool for anxiety disorders at the range between 0.8 and 1.6 (i.e., top 21.2 to 5.5 percentiles). Higher sensitivity (0.795) and specificity (0.937) for identifying anxiety disorders were observed in the K-ANX compared to the BAI and GAD-7. Conclusion The K-ANX is a reliable and valid measure to screen anxiety disorders in a Korean sample, with greater sensitivity and specificity than current measures of anxiety symptoms.

Purpose: The purpose of this study was to develop a Korean Nurse Residency Program (KNRP) in order to facilitate new nurses' transition to clinical practice working at tertiary hospitals in Korea. Methods: The KNRP was developed through a literature review, investigation of NRP cases in United States, two rounds of expert consultation, and appropriateness survey. For appropriateness survey of the program, a questionnaire with 118 items and 14 subcategories including overview and operation of KNRP, education programs, staffing criteria for new nurses' education, preceptor supporting strategies, evaluation standards for new nurse's education, infrastructure, and KNRP benefits was used. Data were collected from 369 nurses including nurse educators, nurse managers, preceptors, and new nurses working at 43 tertiary hospitals in Korea from February 16, 2021 to March 22, 2021. Data were analyzed with descriptive statistics. Results: Appropriateness score of KNRP was 3.42±0.31 (out of 4) and those of 14 subcategories ranged from 3.18±0.47 to 3.58±0.46. The final version of the KNRP postulated is a one-year program, which is composed of off-job training and on-site training including preceptorship over 3 months, and competency reinforcement and adaptation supporting programs. Conclusion: The application of the one-year KNRP will facilitate new graduate nurses' transition to clinical practice. In order for effective application of the KNRP, cooperative efforts of the government, professional associations, and hospitals are needed.

Purpose: The aims of the present study were 1) to quantitatively evaluate the extent of sinus pneumatization and 2) to determine the factors affecting sinus pneumatization. Methods: Based on implant treatment records, a list of patients who underwent implant placement on the posterior maxilla was obtained. Among them, patients with pre-extraction and post-extraction (before implant placement) panoramic radiographs were selected. After excluding radiographs with low resolution and image distortion, the radiographs before and after extraction were superimposed using computer software. Subsequently, the extent of sinus pneumatization (the vertical change of the sinus floor) was measured. Simple and multiple mixed models were used to determine the factors affecting sinus pneumatization. Results: A total of 145 patients were eligible for the present investigation. The average extent of sinus pneumatization was 1.56±3.93 mm at 176 tooth sites. Male sex, single tooth extraction, extraction of an endodontically compromised tooth, a class I root-sinus relationship, and sinus membrane thickening >10 mm favored pneumatization, but without statistical significance. The maxillary second molar presented the greatest pneumatization (2.25±4.39 mm) compared with other tooth types. This finding was confirmed in the multiple mixed model, which demonstrated a statistically significant impact of the extraction of a second molar compared with the extraction of a first premolar. Conclusions: Maxillary sinus pneumatization was 1.56±3.93 mm on average. The extraction of a second molar led to the greatest extent of pneumatization, which should be considered in the treatment plan for this tooth site.
