Objectives: This study aimed to identify the level of occupational and organizational retention intention and related factors among new dental hygienists. Methods: The participants were 195 dental hygienists employed for less than 24 months. A t-test and one-way analysis of variance were conducted to determine the level of intention to stay according to an individual's major-related characteristics and work environment awareness level. Pearson's correlation analysis was performed for each item, and stepwise multiple regression was performed for factors related to retention intention. Results: In the work environment, the organizational support network had the highest occupational retention intention (β=0.513). Organizational retention intention (β=0.351), working infrastructure (β=0.293), cooperation relationship (β=0.165), and management justice (β=0.151) were factors related to organizational retention intention (p<0.001). Employment at the practice hospital was related to occupational (β=0.167) and organizational retention intention (β=0.138), and satisfaction with clinical practice was related to occupational retention intention (β=0.327). Conclusions: New dental hygienists are expected to be actively utilized for long-term tenure in both occupations and organizations by actively reflecting on the results obtained through this study in the curriculum and working environment of dental hygienists.

Purpose: The purpose of this study was to investigate the relationships of Korean medicine (KM) nursing knowledge, nursing practice and role conflict with retention intention among KM nurses. Methods: The study used a survey design with a sample of 152 nurses working at Korean medicine hospitals in Kyunggi province and Seoul. The data were collected from January 15 to March 18, 2016 and were analyzed with SPSS WIN 21.0. Results: The factors that influenced on retention intention were knowledge (${\beta}=.36$, p<.001) and role conflict (${\beta}=-.18$, p=.020) of KM nursing which explained 25.3% of retention intention in KM nurses (F=6.06, p<.001). Conclusion: The findings suggest that it is necessary to develop and offer KM nursing education programs for increasing retention intention among nurses in Korean medicine hospital. It is also important to specify the roles of KM nurses for reducing role conflict.

Objectives: This study aimed to provide basic data for the development of clinical practice-related education program by analyzing the effects of grit, job satisfaction, and retention intention on transition shock of new dental hygienists. Methods: From April 19 to July 4, 2022, the data was collected from 200 new dental hygienists working for dental hospitals/clinics. Using the SPSS Statistics ver. 22.0, this study was conducted the t-test, one-way ANOVA, Pearson's correlation analysis, and multiple regression analysis. Results: There were positive correlations between grit, job satisfaction, and retention intention, a negative correlation between grit and transition shock, a positive correlation between job satisfaction and retention intention, a negative correlation between job satisfaction and transition shock. and a negative correlation between retention intention and transition shock. As the factors affecting transition shock, lower pay and main performance of medical cooperation work increased transition shock. When job satisfaction and retention intention were higher, transition shock decreased. Conclusions: In order to reduce transition shock of new dental hygienists, it would be necessary to operate clinical practice-related training program, and also to establish a training environment similar to the clinical site/context/situation similar to clinical context/situation.

Objective: The aim of this study was to evaluate retention practices commonly employed by orthodontists. The objectives were to identify the types of retainer frequently used and to investigate the variations in retention practice. Methods: A total of 97 orthodontists were randomly selected, and a questionnaire consisting of 25 multiple-choice questions sent to them by mail. Upon receiving of the completed questionnaires, the data were statistically analyzed. Results: A total of 32 responses were received; among these, 59.4% of orthodontists' practiced is in a government setting and 40.6% were in private practice. A vacuum-formed retainer was the most commonly used removable retainer for both maxillary (46.9%) and mandibular (46.9%) arches, followed by a Hawley retainer (maxilla, 43.8%; mandible, 37.5%), and a fixed retainer (maxilla, 3.1%; mandible, 9.4%). Of the responding orthodontists, 78.1% prescribed full-time wear (more than 20 h per day) for a duration of 3-9 months for a maxillary arch, compared to 71.9% for the mandibular arch. Only 18.8% of the orthodontists prescribed part-time wear of the retainer for the maxillary arch, compared to 21.9% for the mandibular arch. The majority of orthodontists did not instruct their patients to stop wearing removable retainers (71.9%) or fixed retainers (66.8%) at any specific time and they preferred their patients to continue wearing retainers. Conclusions: Vacuum-formed retainers are the most commonly used retainers among orthodontists. The majority of orthodontists prescribed full-time wear for more than 20 h per day with a duration of 3-9 months and preferred indefinite use of the retainer.

Several studies have evaluated the effects of types of relative frequency and delay interval of knowledge of results(KR) on motor skill learning independently. The purpose of this study was to determine more effective types of KR relative frequency and KR delay interval for motor learning. Forty-six healthy subjects (15 female, 31 male) with no previous experience with this experiment participated. The subjects ranged in age from 20 to 29 years (mean=23.9, SD=0.474). All subjects were assigned to one of four groups: a high-instant group, a high-delay group, a low-instant group, and a low-delay group. During the acquisition phase, subjects practiced movements to a target (400 mm) with either a high (83%) or low (33%) KR relative frequency, and with either an instantaneous or delayed (after 8s) KR. Four groups were evaluated on retention (after 3min and 24hr) and transfer (450 mm) tests. The major findings were as follows: (1) there were no between-group differences in acquisition and short-term retention (p>0.05, (2) a low (33%) KR relative frequency during practice was as effective for learning as measured by both long-tenn retention and transfer tests, compared with high (83%) KR practice conditions (p<0.05), (3) delayed (8s) KR enhanced learning as measured by both long-term retention and transfer tests, compared with instantaneous KR practice conditions (p<0.05), and (4) there were no interactions between KR relative frequency and KR delay interval during acquisition, retention, and transfer phases. The results suggest that relatively less frequent and delayed KR are more effective types for motor learning than more frequent and instantaneous KR.

During therapy sessions, feedback is often provided concurrently by the physical therapist as the patient attempts to perform a movement and after the movement attempt. This feedback is provided to enhance the patient's balance abilities. However, recent studies in nondisabled populations have suggested that frequent feedback may be detrimental to retention or learning of motor skills. This study compared the effects of 100% relative frequency of knowledge of performance (KP) with 66% relative frequency of KP for motor learning on balance retraining in patients with hemiplegia. Twenty patients with hemiplegic were randomly assigned to one of two experimental groups. The acquisition phase consisted of 16 blocks of 5 trials for 2 days (80 total practice trials). The retention phase consisted of 2 blocks of a short-term retention test, one day after the end of the acquisition phase and a long-term retention test, one week after the end of the short-term retention test. In the 100% feedback condition, participants received feedback after every practice trial. A faded KP schedule was used in the 66% condition. No significant differences were found between the two groups during all experimental phases (acquisition and retention phases), (p>.05). However, there were significant decreases in balance index for both groups of acquisition phase (p<.05). These results suggest that 66% relative frequency of KP is not more effective than 100% relative frequency of KP with respect to retention over time when hemiparetic patients attempt to learn balance.

Purpose: The purpose of this study is to investigate relationship among intention to retention, role conflicts, psychosocial job conditions and job satisfaction of new nurses, and identify affecting factors for intention to retention. Methods: Data were collected from 136 new nurses who were graduated at 2016 and working now in general hospitals by self-reported questionnaire. The relationship among variables were analyzed with Pearson's coefficient correlation and affecting factors for intention to retention were identified by using multiple linear regression analysis. Results: The mean score of intention to retention was $2.63{\pm}0.28$. Intention to retention was significantly different by the working ward, hope period for work, and reason for retention. Intention to retention had positive relationships with work organization and job contents, and job satisfaction, but negative relationships with frequency of role conflict, demands at work. Job satisfaction and meaning of work identified as influencing factors inn intention to retention. Conclusion: It is needed a positive hospital environment to improve adaptation in clinical nursing practice and to emphasize professionalism including value of nursing and meaning of nurses' work for new nurses.

Composite resins, commonly used in clinical practice, have been developed to improve aesthetics to obtain smooth surfaces. Although the restored composite resin has a smooth surface, it gradually becomes rough over time. Therefore, this study measured glossiness to evaluate the surface of various composite resins and attempted to evaluate the maintenance of glossiness of composite resins by observing surfaces that change to roughness. Specimens were produced using resin used in clinical practice: Gradia direct anterior (GA), Tetric N-Ceram (TN), Ceram.X Sphere TEC one (CX), Filtek Z350XT (FT), Estelite sigma quick (ES). After creating a smooth surface with slide glass, five locations were randomly selected to measure surface gloss, and the average was the representative value of the specimen. Roughness was applied to the specimen under water pouring at the same speed and pressure using SiC paper #2400, 1200, and 400. The gloss unit of different SiC papers was measured. To evaluate the gloss unit and gloss retention between composite resins, one-way analysis of variance and Tukey multiple comparisons test were used. As a result of the study, there was a difference in gloss unit of specimens produced under the same conditions. Although the degree differed depending on the composite resin, there was also a difference in gloss retention. Based on the findings, composite resins show differences in gloss due to their different characteristics. Ceram.X Sphere TEC one (CX) showing the lowest gloss retention and Estelite sigma quick (ES) showing the highest.

Objectives: Objectives : This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the patients with Post-stroke Urinary Retention; PSUR. Methods: Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUR compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions: 4 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUR. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as SP6, CV3, CV6, CV4, SP9, BL28, BL23, BL22, KI3 or BL67, for 15-30 minutes. 20-140Hz frequency and 10-20 minutes of treatment is suggested if electro-acupuncture treatment is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. Finally, there was a moderate evidence to support safety of acupuncture treatment for PSUR.
