Purpose: The purpose of this study was to identify registered nurses learning needs about physical assessment. Specifically, what are the perceived competency, frequency of skill use and the unmet training needs. Methods: The study was an exploratory survey study. The sample was 104 registered nurses. Data were collected through three instruments: The Perceived Competency in Physical Assessment Scale, the Frequency of Physical Assessment Scale, and the Training Needs of Physical Assessment Scale which incorporated 30 core Physical Assessment skills. Descriptive statistics, t-test, and Pearson's correlation coefficient were used to analyze the data. Results: Auscultation of heart and lung sounds and inspection of the spine were rated by the subjects as physical assessment skills they feel least competent and also were less frequently performed. The most competent area for physical assessment was neurological system. The respiratory and abdominal system was identified as two systems that more education would be needed. Nurses with less than one year of working experience reported needing more training. Nurses with more than five years of clinical work experience performed physical assessment more frequently than nurses with less than five year of work experience. The perceived competency was positively related to the frequency of physical assessment. Conclusion: Continuing education is necessary to further train registered nurses regarding physical assessment skills and the program needs to be focused on the area which nurses are less competent for and have high training need.

Measuring similarity in collaborative filtering-based recommender systems greatly affects system performance. This is because items are recommended from other similar users. In order to overcome the biggest problem of traditional similarity measures, i.e., data sparsity problem, this study suggests a new similarity measure that is the optimal combination of previous similarity and the value reflecting the number of co-rated items. We conducted experiments with various conditions to evaluate performance of the proposed measure. As a result, the proposed measure yielded much better performance than previous ones in terms of prediction qualities, specifically the maximum of about 7% improvement over the traditional Pearson correlation and about 4% over the cosine similarity.

The purpose of this study was to assess the practical nutrition counseling system by investigating job perception and satisfaction among school nutrition teachers in Kyungbuk area. One hundred and fifty school nutrition teachers were surveyed and 128 answered(85.3%). Data were analyzed by frequency(%), $x^2$-test, and pearson's correlation analyses. Nutrition teachers in elementary schools conducted nutrition counseling more than those in middle schools. In descending order, the reasons for not conducting nutrition education were lack of time, inadequate system for the nutrition counseling, lack of curriculum and lack of facilities. Respondents thought that reduced workload was important to conduct nutrition counseling. However, nutrition counseling should be actively utilized as teachers showed high satisfaction. Therefore, systematic support from related departments combined with effective nutrition counselling methods for nutrition teachers should be continuously provided.

Purpose : The purpose of this study was to identify the association between safety care activity and documentation of nursing records among nurses working in hospitals and to provide basic data for developing hospital policy for the documentation of nursing records. Methods : By using a self-reported questionnaire, data were collected from 212 nurses working in six general hospitals in Jeju province from November 2015. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression with the SAS WIN 9.2 program. Results : Safety care activity was positively correlated with the documentation of nursing records (r=.83, p<.001). The documentation of nursing records was significantly predicted by safety care activity, working department, and nursing delivery system, and 70.9% of the variance in the documentation of nursing records was explained (F=172.31, p<.001). Conclusions : In this study, safety care activity was the most influencing factor for the documentation of nursing records. Improving work circumstances and building a system are required for nurses' safety care activity to lead to good documentation of nursing records.

For a place-recommendation model based on user's behavior and multi-attribute attitude in this thesis. We focus groups that show similar patterns of visiting restaurants and then compare one and the other. We make use of The Fishbein Equation, Pearson's Correlation Coefficient to calculate multi-attribute attitude scores. Furthermore, We also make use of Preference Prediction Algorithm and Distance based method named "Euclidean Distance" to provide accurate results. We can demonstrate how excellent this system is through several experiments carried out with actual data.

The purpose of this study was to collect and analyze personal bio data and social network services (SNS) data, derive user preference and user life pattern, and propose intuitive and precise user modeling. This study not only tried to conduct eye tracking experiments using various smart devices to be the ground of the recommendation system considering the attribute of smart devices, but also derived classification preference by analyzing eye tracking data of collected bio data and SNS data. In addition, this study intended to combine and analyze preference of the common classification of the two types of data, derive final preference by each smart device, and based on user life pattern extracted from final preference and collected bio data (amount of activity, sleep), draw the similarity between users using Pearson correlation coefficient. Through derivation of preference considering the attribute of smart devices, it could be found that users would be influenced by smart devices. With user modeling using user behavior pattern, eye tracking, and user preference, this study tried to contribute to the research on the recommendation system that should precisely reflect user tendency.

Objectives: To confirm the awareness of child abuse and attitudes toward mandatory reporting among dental hygiene students in the Gwangju and Jeonnam regions. Methods: The level of awareness of child abuse according to general characteristics, attitudes toward reporting obligation, and awareness of the mandatory reporting system were analyzed using t-test or one-way analysis of variance (ANOVA) analysis, and correlation was analyzed using Pearson correlation coefficient. Results: Awareness of child abuse was 3.76, 3.68, 3.67, and 3.18 points for neglect, sexual abuse, physical, and emotional abuse, respectively. The attitude toward reporting obligation were 3.60 and 2.62 points for positive and negative reporting attitudes, respectively. Regarding awareness of child abuse, a significant positive correlation was observed between positive reporting attitude (r=0.326, p<0.01) and awareness of mandatory reporting system (r=0.272, p<0.01). Conclusions: To increase the reporting rate among dental hygienists, awareness should be improved starting from the undergraduate level, perceptions of prospective dental hygienists should be reflected in the development and direction of educational programs, and it is necessary to increase accessibility to educational opportunities and continuously seek institutional and policy measures.

This study was to confirm whether students' evaluation of online teaching effectiveness (SEOTE) was significantly predicted by Instructional Material Motivation Survey (IMMS) and Literacy of Learning Management System (LLMS). It was also to examine whether LLMS had a significant mediating effect between IMMS and SEOTE. Pearson correlation, multiple-regression, and mediated regression analysis were used. Participants were online college students in South Korea. A total of 210 students meaningfully responded to the Google Drive web-survey via the internet of three scales: IMMS, LLMS, and SEOTE. This study revealed that motivation had a significant effect on SEOTE (r=.78, p<.01). There was a significant positive correlation between LLMS and SEOTE (r=.64, p<.01). In addition, motivation and LLMS were significant predictors that influenced the prediction of SEOTE. The overall model of IMMS and LLMS significantly predicted SEOTE, explaining 31.4% variance in SEOTE. This study used mediated regression analysis to determine whether there was a significant mediating effect of LLMS between IMMS and SEOTE. As LLMS was added between IMMS and SEOTE, the β coefficient of motivation was decreased. Models of IMMS and LLMS significantly influenced the prediction of SEOTE. LLMS showed a significant mediating effect by influencing the prediction of SEOTE by IMMS according to the method of Baron and Kenny (1986). Consequently, meaningful parameter of LLMS showed a significant indirect or mediating effect with IMMS in predicting SEOTE.

Purpose: To evaluate the correlation between Korean Shoulder Scoring System and Isokinetic muscle strength test for allowance of the return to unrestricted activities after rotator cuff disease treatment. Materials and Methods: This study examined 59 patients with impingement syndrome and 36 patients with rotator cuff tear. KSS and isokinetic muscle strength were analyzed and we sought to evaluate the correlation between total score or each functional parameter scores of KSS and isokinetic muscle strength deficit with Pearson's correlation test. Results: We found a weak negative correlation between and the total KSS score and the endurance test as well (r<0.346). The correlation between the manual muscle test of KSS and isokinetic strength deficits was not significant (p>0.05). Conclusion: The isokinetic muscle strength deficit had a weak correlarion between total score or the edurance test of KSS. Our results suggest that the Isokinetic muscle strength test may be needed for return to normal activity after treatment.
