This research has been conducted to examine the cognition and attitude of nursing students on Oriental Nursing, the subject of this research being 789 nursing students from 9 different universities who took the Oriental Nursing class. A questionnaire, the construct validity and reliability of which have been verified through enquiries into records and references as well as preliminary researches, was used as a research tool. The questionnaire, a set of 86 questions, was developed by the researchers of this study, and the reliability of the questionnaire is Cronbach's=.85. The collected data have been analysed using SPSS windows programme 11.0 for t-test and ANOVA, and the results are as follows: 1. There was a significant difference in cognition and attitude points according to the academic year (F=14.15, p=.000). After the post-hoc test, it was revealed that the points of the students in their 4th year were significantly higher than the points of the students in their 2nd or 3rd year. 2. There was a significant difference in cognition and attitude points according to the credits the students have taken (F=28.66, p=.000). After the post-hoc test, it was revealed that the points of the students who have taken from $3{\sim}5$ to $6{\sim}8$ credits were significantly higher than the points of those who have taken from 1 to 2 credits. 3. There was a significant difference in cognition and attitude points according to the period of time the students have experienced Oriental Nursing (F=32.06, p=.000). After the post-hoc test, it was revealed that the points of the students who have practised Oriental Nursing from 1 to 2 weeks were significantly higher than the points of those who have not practised it at all. 4. There was no significant difference in cognition and attitude points according to the treatment or hospitalisation of the students themselves or their family members. 5. The cognition and attitude points of the students who are deeply interested in Oriental Nursing were significantly higher than the points of those who are not (t=8.83, p=.000). 6. The cognition and attitude points of the students who have higher expectations for the development of Oriental Nursing were significantly higher than the points of those who have not(t=5.90, p=.000). 7. The cognition and attitude points of the students who believe that the Oriental Nursing will contribute to the expansion of the roles of nurses were significantly higher than the points of those who do not (t=6.60, p=.000). 8. The cognition and attitude points of the students who expect that the Oriental Nursing will be effective in prevention of chronic diseases were significantly higher than the points of those who do not (t=5.80, p=.000). According to the results above, it was confirmed that proper education on Oriental Nursing can have affirmative effects on the cognition and attitude of the nursing students towards Oriental Nursing.

PURPOSE. This in-vitro study aimed to evaluate the fracture resistances and failure modes of endodontically treated mandibular premolars restored with endocrowns and conventional post-core retained crowns. MATERIALS AND METHODS. Thirty mandibular premolars were assigned into three groups (n=10): GI, intact teeth; GE, teeth with endocrowns; GC, teeth with conventional post-core supported crowns. Except for the teeth in group GI, all specimens were cut to 1.5 mm above the cementoenamel junction and endodontically treated. Both endocrowns and conventional crowns were fabricated from lithium-disilicate blocks using a CEREC 3D CAD/CAM unit. All specimens were subjected to thermocycling and then to $45^{\circ}$ oblique compressive load until fracture occurred. The fracture resistance and failure mode of each specimen were recorded. Data were analyzed with one-way ANOVA and LSD Post Hoc Test (${\alpha}=.05$). RESULTS. The fracture resistances of GE and GC were significantly lower than that of GI (P<.01), while no significant difference was found between GE and GC (P=.702). As of the failure mode, most of the specimens in GE and GC were unfavorable while a higher occurrence of favorable failure mode was presented in GI. CONCLUSION. For the restoration of mandibular premolar, endocrown shows no advantage in fracture resistance when compared with the conventional method. Both of the two methods cannot rehabilitate endodontically treated teeth with the same fracture resistances that intact mandibular premolars have.

Background: Despite the fact that aquatic exercise is one of the most popular alternative treatment methods for children with cerebral palsy (CP), there are few research regarding its effectiveness. Objects: The purpose of this study was to examine the effects of aquatic exercise on upper extremity function and postural control during reaching in children with CP. Methods: Ten participants (eight males and two females; 4-10 years; Gross Motor Function Classification System levels II-IV) with spastic diplegia were recruited to this study. The aquatic exercise program consisted of four modified movements that were selected from the Halliwick 10-point program to enhance upper extremity and trunk movements. The participants attended treatment two times a week for 6 weeks, averaging 35 minutes each session. The Box and Block Test (BBT), transferring pennies in the Bruininks-Oseretsky Test (BOT), and pediatric reaching test (PRT) scores were used as clinical measures. Three-dimensional motion analysis system was used to collect and analyze kinematic data. Differences in BBT and BOT values among pre-treatment, post-treatment, and retention (after 3 weeks) were analyzed using a Friedman test. In addition, the PRT scores and variables (movement time, hand velocity, straightness ratio, and number of movement units) from the three-dimensional motion analysis were tested using a Wilcoxon signed-rank test. The significance level was established at p < 0.05. When the results appeared to be statistically significant, a post-hoc test for multiple comparisons was performed with the Wilcoxon signed-rank test. Results: All clinical measures, which included BBT, transferring pennies of BOT, and PRT, were significantly increased between pre-intervention and post-intervention scores and between pre-intervention and retention scores after treatment (p = 0.001). Three-dimensional motion analysis mostly were significantly improved after treatment (p = 0.001). Conclusion: Aquatic exercise may help to improve body function, activity, and participation in children with varying types of physical disabilities.

Objectives: This study compared the cyclic fatigue resistance of nickel-titanium (NiTi) files obtained in a conventional test using a simulated canal with a newly developed method that allows the application of constant fatigue load conditions. Materials and Methods: ProFile and K3 files of #25/.06, #30/.06, and #40/.04 were selected. Two types of testing devices were built to test their fatigue performance. The first (conventional) device prescribed curvature inside a simulated canal (C-test), the second new device exerted a constant load (L-test) whilst allowing any resulting curvature. Ten new instruments of each size and brand were tested with each device. The files were rotated until fracture and the number of cycles to failure (NCF) was determined. The NCF were subjected to one-way ANOVA and Duncan's post-hoc test for each method. Spearman's rank correlation coefficient was computed to examine any association between methods. Results: Spearman's rank correlation coefficient (${\rho}$ = -0.905) showed a significant negative correlation between methods. Groups with significant difference after the L-test divided into 4 clusters, whilst the C-test gave just 2 clusters. From the L-test, considering the negative correlation of NCF, K3 gave a significantly lower fatigue resistance than ProFile as in the C-test. K3 #30/.06 showed a lower fatigue resistance than K3 #25/.06, which was not found by the C-test. Variation in fatigue test methodology resulted in different cyclic fatigue resistance rankings for various NiTi files. Conclusions: The new methodology standardized the load during fatigue testing, allowing determination fatigue behavior under constant load conditions.

Purpose: The purpose was to examine the self-efficacy, coping, and compliance in patients with kidney transplantation. Methods: Participants consisted of 300 outpatients who underwent kidney transplantation and regularly visited hospital for health check-up. A tool developed by Ahn (2000) was used for measuring self-efficacy. A modified version of the Jalowiec Coping Scale (Jalowiec, 1987) by Hwang (2004) was used for measuring coping, and a tool developed by Ryu, Kim, and Kang (2003) was used for compliance. Data were analyzed using SPSS program version 21.0 ANOVA, Pearson's correlation coefficient, and Scheff$\acute{e}$'s test for post-hoc test. Results: Coping shows significant differences according to marital status and education. Coping was used more often among patients with ABO incompatible transplantation than those with ABO compatible. Differences in compliance were significant according to donor type, ABO incompatible, period after transplantation, and admission after the transplantation. The management of life style, stress, nutrition, and exercise in self-efficacy and compliance had lower scores than the others. Conclusion: There are significant correlations between self-efficacy, coping, and compliance in patients with kidney transplant which might be helpful for health care professionals in taking care of these population.

Purpose: The purpose of this study was to identify factors associated with smartphone overdependency in preschool children based on an analysis of mother, child, and their mutual dyadic relationships. Methods: Data were collected from 171 mothers of preschool children enrolled at daycare centers and kindergartens from January to March 2018. The data were analyzed by descriptive statistics, the t-test, analysis of variance with $Scheff{\acute{e}}$ post hoc test, Pearson correlation coefficient, and hierarchical regression analysis using SPSS version 24. Results: The self regulation of preschool children (${\beta}=-.358$, p<.001) was the factor most closely associated with smartphone overdependency. The second most closely associated factor was children's use of a smartphone 0.5-1 hour daily (${\beta}=-.249$, p=.005). Additional associated factors were mothers' use of a smartphone for 3-4 hours daily (${\beta}=.217$, p=.002), children's use of a smartphone for less than 0.5 hour daily (${\beta}=-.212$, p=.006), and children's use of a smartphone for 1-2 days per week (${\beta}=-.205$, p=.026). Conclusion: Based on the results of this study, it is necessary to try to develop guidelines and programs to prevent smart phone overdependency in preschool children.
