The OTT (Over The Top) platform promotes itself as a distinctive competitive advantage in that it allows users to stay on the platform longer and visit more often through a Personalized Recommendation Service. In this study, the characteristics of the Personalized Recommendation Service are divided into three categories: recommendation accuracy, recommendation diversity, and recommendation novelty. Then proposed a research model which affects the usefulness of users to recognize recommendation services by each characteristics and leads to satisfaction of expectations. The result of conducting an online survey of 300 people in their 20s and 30s who subscribe Netflix shows that the perceived usefulness increased when the accuracy, variety, and novelty of Netflix's Recommendation Service were high. It was also confirmed that high perceived usefulness leads to satisfaction of expectations before and after Netflix use. The derived research results can confirm the importance of evaluating the personalized recommendation service in terms of user experience and provide implications for ways to improve the quality of recommendation services.

This research investigated the effects of university library users' use patterns and their recognition of service benefits on the magnitude of service value assessments derived from users' statements using contingent valuation method (CVM). Library users' use patterns were operationalized by the number of library visits, library website visit counts and the degree of dependence on their own libraries. User benefits variables were measured by the level of satisfaction on the benefits of library use for teaching & instruction, research & writings, and employment & external activities. University library services were divided into circulation, journal articles (domestic & foreign), reference service, user education, reading room service and WTPs for each service were measured. The results from hypotheses testing show that the number of library visits affect WTP amounts for circulation, foreign article use, reference service and user education. The degree of library dependence seems to affect WTP amounts for circulation and user education. With regards to the hypotheses related to the recognition of library service benefits, the degree of satisfaction for teaching & instruction benefits seems to affect WTP amounts for reading room use.

Background: Rotator cuff tears cause pathologies of the long head of the biceps tendon (LHBT). One of the surgical treatments for such a tear is LHBT tenodesis to the humerus. This study aims to compare simultaneous rotator cuff repair and LHBT tenodesis with or without detachment of the proximal end of the LHBT (PELHBT) from its site of adhesion to the glenoid. Methods: This retrospective study involved patients affected by LHBT pathology with rotator cuff tear. The patients were divided into two groups, with or without PELHBT detachment from the glenoid. Therapeutic outcomes were investigated by evaluation of patient satisfaction, pain based on visual analog scale, shoulder function based on Constant score and simple shoulder test, and biceps muscle strength based on the manual muscle testing grading system before surgery, at 6 months, and at the final visit after surgery. Results: Groups 1 and 2 comprised 23 and 26 patients, respectively, who showed no significant differences in demographic characteristics (p>0.05). Shoulder function, biceps muscle strength, pain, and satisfaction rate improved over time (p<0.05) but were not significantly different between the two groups (p>0.05). No post-surgical complication was found in either group. Conclusions: There was no difference in final outcomes of tenodesis with or without detachment of the PELHBT from the supraglenoid tubercle. Such tendon detachment is not necessary.

The design of a museum mobile application's user experience demands an in-depth comprehension of the user experience dimensions and the unique attributes of the user experience elements that users may encounter. This paper through a series of experimental studies and analyses of experiences related to the use of museum mobile applications, derives a user experience framework consisting of four dimensions and 19 elements, which has been verified for feasibility. The study shows that all four dimensions have a positive impact on user satisfaction, but the degree of impact varies. Among them, emotionality of use and ease of use have the greatest impact, while usefulness of use and multiformity of function have relatively less impact. In addition, the user experience of museum mobile application can also positively influence the user's future intention to recommend, continue using, and even the actual visit to the museum.

Educational web sites are proliferating at an astonishing rate, however many of those web sites are of poor or unknown quality. Educators are in need of instruments to assist in evaluating educational web sites for authenticity, applicability, authorship, bias, and usability, etc. The ability to critically evaluate educational content form numerous web sites is an important skill in this information age. In this paper, indicators of educational web site quality have been identified from literature review and our own research, and classified within 8 categories. To test the relative contribution of each indicator to the satisfaction level from using educational web sites, a questionnaire survey was administered. Subjects were asked to visit the educational web site of his or her choice and rate the quality level of each indicator. 255 completed questionnaires were turned in for analysis. Cronbach's Alpha test and factor analysis were applied to test the reliability and validity of the data. Stepwise regression analysis was applied to test the relationship between the satisfaction level and 14 independent factors. Implications from the statistical analysis as well as the guidelines for evaluating educational web sites were provided.

Purpose: Cow's milk protein allergy (CMPA) is a common condition in infants, but little is known about healthcare providers' clinical experience treating infants with CMPA. To address this gap, we analyzed prospectively collected data from healthcare providers (HCPs) who treated infants under six months old with suspected CMPA using hypoallergenic formulas. The study focused on a commercial extensively hydrolyzed formula containing Lactobacillus rhamnosus GG (ATCC53103) (eHF-LGG) or a commercial amino acid formula (AAF). Methods: In this secondary analysis of prospectively collected survey data, 52 HCPs treated 329 infants under six months old with suspected CMPA using hypoallergenic formulas. A series of two de-identified surveys per patient were collected by HCPs to assess short-term symptom relief in the patients and HCP's satisfaction with the management strategies. The initial survey was completed at the initiation of treatment of CMPA, and the second survey was completed at a follow-up visit. Results: The majority of HCPs (87%) in the study were general pediatricians, and most saw 2 to 10 CMPA patients weekly. Results showed that clinicians reported satisfaction with treatment in 95% of patients in the EHF cohort and 97% of patients in the AAF cohort and achieved expected clinical results in 93% and 97% of patients using eHF and AAF, respectively. Furthermore, few patients were switched from the hypoallergenic formula once initiated. Conclusion: The study provides new insights into HCP perspectives on treating infants with CMPA and supports using hypoallergenic formulas to manage this condition. However, additional prospective controlled studies are needed to confirm these initial findings.

Purpose: Report of the good results of breast reconstruction using Becker permanent tissue expander that showed a short operation time and a quick post-operation recovery time, little side effects and usually superb aesthetic results without the need for additional incisions or donor site morbidity. The authors, after carrying out breast reconstruction operations using Becker permanent tissue expander on patients with appropriate indications, attempted to analyze several factors such as complication rates and patient satisfaction measurements. Methods: 11 cases of breast reconstruction using Becker expander implants were carried out on a total of 10 patients between March 2000 and February 2003. The patients were followed up at outpatient visit for an average of 6 months. Results: The most common post-operation complication was pain resulting from saline injection into the expanders, complained by 5 patients(50%). rib fractures, skin necrosis, implant removal due to infection, and breast cancer recurrence each occurred in 1 patient (9.9%). There was no occurrence of skin contracture complications which occurs frequently in case of silicone implant insertion. Patient complacency was surveyed by patient interviews made right after the operations and during outpatient follow-up periods: 5(50%) patients out of 10 showed excellent, 3(30%) good, and 2(20%) showed fair, leaving no patients who were disappointed with operation results. On routine follow-up, 80% of patients expressed satisfaction with the cosmetic outcome of their post-mastectomy beast reconstruction. Conclusion: Breast reconstruction using the Becker expander is a reliable alternative to other reconstructive methods but good patient selection is essential for satisfactory results.

Purpose: The study was to develop a tailored education and coaching program (TECP) for cancer patients, and to identify the effects of TECP on pain severity, daily living impairment, barriers on pain management, self-efficacy, and pain management satisfaction. Methods: A randomized controlled trial was used. Patients referred to an oncology nurse specialist from oncologists for pain management were randomly assigned to TECP (25) or usual education program (UEP, 22). The intervention was offered by educating the method of taking opioid medication, managing opioid-induced side effects, reducing pain misconceptions and enhancing self-efficacy for communicating with a medical team on cancer pain severity, and pain-related impairment. Patients completed questionnaires before the education program and on the next visit 3~4 weeks later. Data were analyzed by SPSS 19.0 program using percentage, frequency, mean, standard deviation, x² test and independent t-test. Results: At all levels, pain severity improved significantly in the experimental group-worst pain (8.16 to 3.80, p<.001), average pain (6.16 to 2.52 p=.008), and least pain (3.32 to 0.96, p=.038)-but not in the control group. Pain management satisfaction also showed significant differences (t=2.93, p=.005) between experimental (4.70±0.49) and control (4.17±0.73) groups. Interference with daily living, barriers to managing cancer pain, and self-efficacy for managing pain improved in both groups but there were no significant differences. Conclusion: The findings suggest that TECP should be considered for outpatients who need cancer pain management.

Purpose: To evaluate correlation between the clinical results and causative bacteria in diabetic foot patients with lower extremity amputation. Materials and Methods: One hundred twenty nine patients(131 feet) of diabetic foot amputations were followed for more than one year. Wound cultures were done by deep tissue or bone debris at first visit to our clinics. Retrospective analysis was performed using chart review and interview with the patients. Depending on the culture result, level of amputation, reinfection, duration of treatment, death rate, patient satisfaction and admission dates were evaluated. Results: Microorganisms were confirmed in 114 cases. In the other 17 cases, there were no cultured microorganisms. In bacterial growth group, Methicillin-sensitive Staphylococcus aureus was the most common pathogen and accounted for 34 cases. As other common pathogens, there were Methicillin-resistant Staphylococcus aureus(24 cases) and mixed infection(14 cases). Mortality is no difference in each infected group. Mixed bacterial infected patients have higher reinfection, longer hospital day and duration of treatment, but there is no difference in patients satisfaction and pain at last follow up. Conclusion: The most common pathogen in diabetic foot patients with lower extremity amputation was Methicillin-sensitive Staphylococcus aureus, and mixed bacterial infected patients have higher reinfection rate, longer admission date and duration of treatment than other bacterial infected patients.
