본 논문에서 기존의 혈액투석기는 회전하는 모터를 사용하여 구성하였으나 이러한 모터는 정밀도, 반복정밀도가 50um 이하로 가공물 가공시에 치기공사나 치과의사가 사람에 맞추어 다시 작업을 해야하는 불편함과 시간적, 작업자의 피로도를 높일수 있는데 이러한 모터에 스크류나 밸트를 연결하여 선형적으로 움직일 수 있는 리니어모듈과 리니어모터를 적용하게되면 20um수준의 고정밀의 위치 제어가 가능한 혈액투석기를 만들 수 있었다. 또한 MEMS센서를 이용하여 모터의 상태를 모니터링하고 임계값을 지정하여 이상 신호 발생시 모터를 멈추어 위험상황에 대해서 인공지능기법을 이용하여 정지하거나 관리자에게 알림을 주어 효과적으로 혈액투석기를 운영할 수 있도록 하였다.

This study was conducted to investigate the factors that influence the psychosocial adaptation and quality of life of hemodialysis patients. The study participants consisted of 246 hemodialysis patients from 8 hemodialysis centers located in 3 cities ('K', 'P', and 'U') in South Korea. The questionnaire used for data collection was administered between April 1 and 30 of 2014. SPSS/WIN 18 program was used to perform descriptive, correlation, and stepwise regression analyses. It was found that stress response and acceptance were significantly correlated with psychosocial adaptation and quality of life. In the stepwise regression analysis, stress response appeared to be the most important influencing factor for psychosocial adaptation (${\beta}$=-.443, p<.001) and quality of life (${\beta}$=-.553, p<.001). Based on the study results, it is determined that in order to improve psychosocial adaptation and quality of life among hemodialysis patients, an intervention program to reduce stress response is needed, along with evaluating its efficacy.

The research was to identify difference of values of the self-esteem, resilience and quality of life of hemodialysis patients. The survey was conducted to collect data between February 1 and 28 of 2020. SPSS/WIN 20 program was used to perform descriptive, correlation, and multiple regression analyses. In the correlation analysis, Cohabitation form(r=.262, p<.01), Economic status(r=.278, p<.01), Current health status recognition(r=.294, p<.01), Self-esteem(r=.547, p<.01), Resilience(r=637, p<.01) turned out to be influential factor for self-esteem, resilience, and quality of life according to general and disease of characteristics. Therefore, on the basis of this research, it is meaningful to provide basic data for the development of nursing interventions that allow one to embrace one's health condition and find the meaning of life in order to improve the quality of life of hemodialysis patients.

Chronic diseases is being increased attention to threatening the elements healthy life of elderly population in modem society. Especially, Chronic diseases caused by diabetes and hypertension is destroyed kidney. In this case, subjective symptom is not little. So if health is worsened, hemodialysis, artificial organs, transplant an organ etc. should be treated as a dangerous diseases. Therefor, a patients receiving hemodialysis of diabetes and hypertension studied on the effects to regularity of amplitude and rate vibration of vocal cords in hemodialysis in this paper. To do this, a diabetic and hypertensive patients don't have a problem with pronunciation selected as of the subjects and their voices collected before and after hemodialysis. We studied on the effects of voice analysis to apply regularity of amplitude and rate vibration of vocal cords. In conclusion, we extracted a result that voice after than before hemodialysis is relatively low in voice measures values a regularity of amplitude and rate vibration of vocal cords.

The purpose of this study was to identify and analyze the communication behavior styles of hemodialysis nurses based on the structured Q-methodology. The Q-population was formulated based on literature reviews and in-depth interviews with 10 hemodialysis nurses who were working in hospitals in Seoul and Anyang-si, Gyeonggi Province. A total of 50 Q-samples, which were believed to best represent the communication behavior styles of hemodialysis nurses, were selected from the Q-population by the author and a professor majoring in nursing. 30 P-samples were selected from hemodialysis nurses who were working in primary, secondary, and tertiary hospitals in Seoul. Q-sorting was performed by P-samples and data was analyzed through the pc-QUANL program. The results suggested that there are four types of communication behavior styles of hemodialysis nurses, namely: "type I: listening and speaking courteously with an active mind", "type II: listening and speaking courteously with a receptive mind", "type III: advising with an explanation" and "type IV: super-reasonable with a defensive mind". It is expected that the analytical results described here may provide basic information that can be used to develop educational material for hemodialysis nurses.

The purpose of the study was to evaluate patients' compliance with the hemodialysis and to investigate relationships between compliance, physiological parameters, and health-related quality of life. Data were collected from 220 patients at 27 local hemodialysis clinics. Compliance was measured with Sick-role Behavioral Compliance including interdialytic weight gain, serum potassium, and phosphorus. Health-related quality of life was assessed using Medical Outcomes Study Short Form-12. Data were analyzed using descriptive statistics, t-tests, ANOVA, and Pearson correlation. Total compliance scored 2.92 out of 4 points on average. Among fifteen items, 'I keep on my dialysis schedule(time and date)' was the highest score. There were differences in the scores for compliance according to age, marital status, and dialysis period. Statistically significant correlations were found between four compliance items(medication, infection control, sleep, eating vegetable and fruit) and health-related quality of life. The results of the study indicate that a patient-centered approach would be helpful to improve quality of life in patients with hemodialysis. Healthcare providers need to understand the patients' perspectives by identifying what is important to patients and taking patient values and priorities into account.

The purpose of this study was to identify the experience symptoms and severity of hemodialysis patients and to determine the effects of each symptom on health related quality of life. This research involved 102 patients who were receiving hemodialysis at one university hospital and two Kidney Center in D city. Data collection were collected from April to May 2014. Data analysis was performed by SPSS/WIN 18.0 using ANOVA, t-test, Pearson correlation and stepwise multiple regression. Fatigue was the highest among symptoms on hemodialysis patients and dry skin, itching was in order. Factors affecting health related quality of life were income and symptoms level. These factors explain 42.2% of the variance in health related quality of life. Based on the results, it is necessary to develop various programs and apply for nursing interventions to alleviate the experience symptoms and severity and expand support in social service perspective in hemodialysis patients. Especially, we suggest that further research for developing nursing interventions for relieving fatigue, itching, and sleep disorders of hemodialysis patients.

The purpose of this study was to examine the predictive relationships between the predictors and self-esteem among hemodialysis(HD) patients. Predictive correlational design, participants 154 HD patients in the Seoul. SPSS for Window 22.0 used to perform descriptive statistics, Pearson's Correlation Coefficient and Stepwise Regression analysis. The strongest predictor was uncertainty (${\beta}=-.33$, p<.001), economy (${\beta}=.18$, p<.05), occupation (${\beta}=.17$, p<.05) and health status (${\beta}=.16$, p<.05) were followed. A total explained variance was 30.0% of self-esteem (Adjust $R^2=.30$). Managing or preventing uncertainty, providing vocational education in consideration of the dialysis environment, providing employment, increasing economic level, and maintaining good health status are factors that enhance self-esteem. Conducted to investigate the self-esteem of HD patients considering the machine-dependent characteristics, future, provide the data of the study to improve the self-esteem of HD patients. Also, nursing intervention should be developed based on the findings.
