Purpose: This study was to investigate the factors influencing the quality of life of patients with hemophilia and to provide the data for health promoting intervention in order to improve their quality of life. Method: The subjects of this study were involved 186 male patients with hemophilia by convenience sampling. These results were analyzed statistically by frequency, percentage, t-test, ANOVA, Pearson Correlation Coefficient, and Stepwise multiple regression. Results: There were significant differences in the quality of life according to the frequency of bleeding. Quality of life showed negative relationships and health problems, bleeding, limitation of joint motion, and depression with stepwise Multiple Regression analysis for quality of life revealed that the most powerful predictor was depression. Depression, health problem, and limitation of joint motion accounted for 64.6% of the variance in the quality of life of patients with hemophilia. Conclusion: Therefore it is necessary to develop nursing interventions with these variables to increase the quality of life for patients with hemophilia.

Purpose: The purposes of this study were to examine health-related quality of life and to identify the mediating effect of resilience on the relationship among uncertainty, distress, and health-related quality of life in lung cancer patients. Methods: A total of 149 lung cancer patients visiting the D hospital in B city completed a questionnaire, including demographic and disease-specific characteristics, uncertainty, distress, resilience, and health-related quality of life. Data were analyzed with descriptive analysis, t-tests, ANOVA, and multiple regression analyses via SPSS 24. Results: Health-related quality of life was $81.00{\pm}21.39$ (range 0~136) in lung cancer patients. In the results of hierarchical regression analyses, the health-related quality of life was associated with education, uncertainty, distress, and resilience. However, there was no mediating effect of resilience on the relationship among uncertainty, distress, and health-related quality of life. Conclusion: Lung cancer patients with high uncertainty and distress and low resilience could experience low health-related quality of life. In order to reduce uncertainty and distress, it is necessary to provide more detailed, systematic information and support, while reinforcing positive thinking.

Background: Related to escalating health care costs and the questionable effectiveness of multiple interventions including lumbar facet joint interventions, cost effectiveness or cost utility analysis has become the cornerstone of evidence-based medicine influencing coverage decisions. Methods: Cost utility of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain was performed utilizing data from a randomized, double-blind, controlled trial with a 2-year follow-up, with direct payment data from 2016. Based on the data from surgical interventions, utilizing the lowest proportion of direct procedural costs of 60%, total cost utility per quality adjusted life year (QALY) was determined by multiplying the derived direct cost at 1.67. Results: Patients in this trial on average received $5.6{\pm}2.6$ procedures over a period of 2 years, with average relief over a period of 2 years of $82.8{\pm}29.6$ weeks with $19{\pm}18.77$ weeks of improvement per procedure. Procedural cost for one-year improvement in quality of life showed USD $2,654.08. Estimated total costs, including indirect costs and drugs with multiplication of direct costs at 1.67, showed a cost of USD $4,432 per QALY. Conclusions: The analysis of therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain shows clinical effectiveness and cost utility at USD $2,654.08 for the direct costs of the procedures, and USD $4,432 for the estimated overall cost per one year of QALY, in chronic persistent low back pain non-responsive to conservative management.

Consideration of Glenohumeral joint's image with the Changed Body angle of the Glenohumeral joint's Oblique Position in Erect Position. Glenohumeral joint's of Grashey method is a shoulder oblique method available to view the shoulder joint. Grashey method projects AP view of the Glenohumeral joint's so that the Humerus head's subluxation or joint degeneration can be easily visualized. However in this view, the patients, erect position, have to keep their body obliquely. Oblique position is will be needed to get the good quality Glenohumeral joint's view. Therefore, we thought of examining a method which shows the Glenohumeral joint's well by angling the patient one side upward in erect position. For this study, total 20 subject with no history of neurological or psychiatric illness, were recruited for examinations. They consisted of 13 mails and 7 femails, Statistic group analysis was performed with ANOVA test. Score of the evaluation of the expects were $30^{\circ}$ at $0.40{\pm}0.499$, $35^{\circ}$ at $1.34{\pm}0.657$, $40^{\circ}$ at $1.84{\pm}0.573$, $45^{\circ}$ at $0.76{\pm}0.649$, and they were significant(P<0.05). The degree of $40^{\circ}$ views were shown to yield good quality shoulder oblique images.

In digital broadcasting, services such as digital satellite TV, cable TV and digital terrestrial TV, several video programs are compressed by MPEG-2, and then simultaneously transmitted over a conventional CBR (Constant Bit Rate) broadcasting channel. In this paper, we propose a joint quality control scheme to be able to accurately control the relative picture quality among the video programs, which is achieved by simdt;,nL'Ously controlling the video encoders to generate the VBR (Variable Bit Rate) compressed video streams. Our quality control scheme can prevent the video buffer overflow and underflow by total target bit allocation process, and also exactly control the relative picture quality in terms of PSNR (Peak Signal to Noise Ratio) between some programs requiring higher picture quality and others by rate-distortion modification. Furthermore we present a rate-distortion estimation method for MPEG-2 video, which is base of our joint quality control, and verify its performance by experiments. The most attractive features of this estimation method are as follows: 1) computational complexity is low because main operation for the estimation is to calculate the histogram of OCT coefficients into quantizer; 2) estimation results are very accurate enough to be applied to the practical MPEG-2 video coding applications. Simulation results show that the proposed joint quality control scheme accurately controls the relative picture quality among the video progran1s transmitted over a single channel as well as provides more consistent and higher picture quality than independent coding scheme that encodes each program independently.

Since a butt Joint is smaller than a lap type joint, it is expected to have smaller AC losses. The butt joint is produced by the diffusion bonding of the contacting surface under pressured and heated condition. It is important to find robust joining conditions, because butt joint has small contact area and has the shape by which the quality of bonding is hard to be checked. In this research, the loading pressure is considered as the joining parameter to find optimum joining condition. The DC resistance of the joint may be changed by the surface pressure during joining process, because the superconducting strands near the contact surface are failed by large plastic deformation. The range from 10 MPa to 18 MPa is expected optimum surface pressure in the conditions of 1 hour heating time and $750^{\circ}C$ temperature in the vacuum furnace.

The purpose of this research is to study customer-supplier relationships, particularly their partnerships, to help managers and practitioners successfully design, develop, implement and deploy tools and joint practices as a means for an effective supply chain management (SCM). To achieve this purpose, a total of 1,811 potential survey questionnaire respondents responsible for purchasing, sales/marketing, quality-, and production- or operations-related functions of U.S. private manufacturing companies in SIC 35, 36, and 37 were used to collect quantitative data. Using 172 usable survey questionnaire responses, eight hypothesized relationships were tested using two independent (joint use of specific tools and joint practices) and four dependent variables (informed partners, role integrity, conflict resolution, and mutuality). From the overall perspective (customer+supplier), organizations with higher levels of joint action have higher degrees of informed partners whereas organizations with higher levels of joint action resolve conflicts formally and do not have higher degrees of mutuality.

Background: In the treatment of temporomandibular joint (TMJ) disorder, the goals of traditional physical therapy are not only to reduce the inflammatory process leading to pain, but also to decrease joint overload and muscle hyperactivity. To achieve those goals, physical therapists generally use a photo-therapy, joint mobilization, and massage. Objects: To examine the impact of an unloading technique using non-elastic taping on the pain, opening mouth, functional level, and quality of life in patients with TMJ disorder. Method: Twenty patients with TMJ disorder were included in this study and randomly divided into the experimental ($n_1$=10), and control ($n_2$=10) groups. Traditional physical therapy including massage and stretching for 30 min was performed in both groups. Non-elastic taping was performed in the experimental group after traditional physical therapy, and they were recommended to keep the tape attached for 12 hours. Outcomes for pain, functional level, and quality of life were measured using a survey. The opening mouth was measured using a general ruler. Result: Significant differences were observed in the pain level, opening mouth, functional level, and quality of life after the intervention and on follow-up in both groups. However, we found that while the levels of all parameters were maintained throughout the follow-up period in the experimental group, the functional status level was not maintained throughout the follow-up period in the control group. Conclusion: Our unloading technique using non-elastic tape results comparable to those achieved by traditional physical therapy in the treatment of TMJ. However, the unloading taping method using non-elastic tape is more effective than traditional physical therapy in maintaining the impact of intervention.
