This study was conducted to identify the conceptual definitions and attributes of fatigue in hemodialysis patients based on the Hybrid Model of concept development. The Hybrid Model was used to investigate the main attributes and indicators of the concept by applying three stages. After a literature review, data were collected through observation and interviews including qualitative research in the field work stage. The participants included 10 patients in hemodialysis center of two hospitals in Gwang-ju, Korea. The attributes of fatigue concept in the hemodialysis patients were divided into four dimensions, physical activity, affective mood, social role, and cognitive reflection. The definition of fatigue by hemodialysis patients was defined as 'subjective feeling usually experienced in four dimensions during the process to recognize and adjust energy deficiency and limited functions caused by uremia and repeated hemodialysis for chronic renal failure'. Considering the dimensions and attributes derived from this study, it may be possible to develop an effective intervention program for fatigue in hemodialysis patients.

The demands for specially trained hemodialysis nurses are increasing as the population requiring maintenance hemodialysis expands. However, there has been no standardized training program for hemodialysis nurses in South Korea. The study was conducted to develop and evaluate a hemodialysis nurse educational program (HNEP). The effects of education using the HNEP were assessed by levels of hemodialysis-specific knowledge, self-efficacy and satisfaction. A total of 25 registered nurses participated in the HNEP which consists of 20 week education (classroom theory for 10 weeks and clinical practice for 10 weeks) between April and September, 2011. Knowledge levels were compared before and after the HNEP using paired t-test. Self-efficacy and satisfaction levels were also evaluated after the program using a scale of 1-5, 5 being the highest and 1 being the lowest. Knowledge levels were significantly increased after the HNEP (Mean=13.96 vs. 17.80, t=-7.748, p=<.001). Self-efficacy and satisfaction levels with the program were high, $3.90{\pm}0.42$ and $4.02{\pm}0.77$, respectively. These findings suggest that the HNEP improved hemodialysis-specific knowledge, and levels of self-efficacy and satisfaction with the HNEP were reasonably, among the participants.

Background/Aims: Assessment of fluid status in hemodialysis patents is very important. Overhydration in hemodialysis is associated with generalized edema, cardiovascular complications, and hypertension. The aim of this study was to determine the factors correlated with mortality of hemodialysis patients, assessing body muscle mass and fluid status using bioelectrical impedance analysis (BIA). Methods: This study enrolled 93 patients who underwent hemodialysis between January 2010 and May 2015 at CHA Bundang Medical Center. Medical records of enrollees up to June 2017 were reviewed retrospectively. These included laboratory results (serum albumin, C-reactive protein [CRP], lipid profile, etc.) and BIA data (extracellular water, intracellular water, total body water, soft lean mass, fat free mass, skeletal muscle mass, etc.). Results: Eleven of 93 patients had expired by May 2017. Among the surviving subjects, mean age was younger, CRP levels were lower, albumin levels were higher, and extracellular water/total body water (ECW/TBW) ratios were lower than in the expired patient group. Kaplan-Meier survival analysis revealed that overhydration (ECW/TBW > 0.4) was associated with higher mortality. Conclusions: In hemodialysis patients, overhydration is an important factor in mortality, and BIA could be a reliable modality in its assessment. We suggest that, for hemodialysis patients, overhydration is more of a risk factor for mortality than is muscle wasting.

This study aimed to develop a valid and reliable self-management instrument for pre-dialysis patients with chronic kidney disease (CKD). A total of 143 patients with CKD recruited from a medical center completed the questionnaire. The dimension and items of self-management were composed by literature review. The items of self-management was evaluated using exploratory factor analysis and measures of reliability. Five factors were extracted and labelled adherence to treatment regimen and partnership, diet adherence, problem solving, health behavior, and pursuit of psycho-social health. The five factors accounted for 51.1% of total variance. Each factors showed acceptable internal reliability with Cronbach's alpha from 0.64-0.79. The developed self-management instrument can be useful in self control of their disease for patients with CKD, and both evaluating patients' self-management and developing intervention program for health care professionals.

This study has been conducted to investigate the effect of self awareness of halitosis on the quality of life related to oral health in patients with chronic renal failure undergoing hemodialysis and use basic data related to oral health of patients with chronic renal failure which is very rare in Korea. In terms of oral symptoms based on awareness of halitosis, there were significant differences in symptoms of teeth pain in the past one month, bleeding gums, symptoms of tongue or cheek pain, dry mouth, In terms of status of oral functions, there were significant differences in discomfort upon chewing foods, difficulty of pronunciation and presence of lost teeth. As the results of analysis of effect of self awareness of halitosis on the quality of life related to oral health in patients with chronic renal failure, it was shown that there were significant effects in psychological discomfort(B=-2.028, p<.01), poor social skills(B=2.596, p<.01) and social disadvantage(B=-2.173, p<.01). Thus, because self awareness of halitosis gives psychologically and socially negative effects, it could be an important factor to patients with renal failure whose number is rapidly increasing.

만성신부전증 환자 절반가량에서 당뇨병이 원인인 것으로 드러나면서 당뇨병성 신증에 대한 심각성이 제기되고 있다. 당뇨병에 의한 말기신부전은 생명을 이어가려면 투석과 신장이식이 불가피한 질병으로 일상에 불편을 가져오는 것은 물론 결국 사망에 이르게 하는 치명적인 질환이다. 중앙대학교 병원 신장내과 유석희 교수는 "당뇨로 인한 반성신부전은 다른 원인으로 인해 발생하는 신부전보다 생존율이 낮다"며 "당뇨병이 오래된 환자일수록 신장합병증이 발병률이 높아지는데, 당뇨병환자가 늘 혈당관리에만 매달리다보면 신장기능이 나빠지는 신호를 놓칠 수 있다"고 전했다.

This study was performed to examine the effects of Dan Jeon Breathing on depression, anxiety and fatigue of hemodialysis patients. This study used the nonequivalent control group pretest-posttest design. Before applying the Dan Jeon Breathing program, the patients were divided into the experimental group and the control group, respectively, and were requested to report their self-ratings to measure their depression, anxiety and fatigue. The Dan Jeon Breathing program was given to both groups for 60 minutes a day and 2 times a week for 12 weeks. The data collected from the program were analysed by means of ${\chi}^2$ test, Fisher's exact probability test, Shapiro-Wilk, t-test and Mann-Whitney U test. The analyses revealed that the depression (t=-2.459, ${\rho}$=.019) and anxiety (t=-2.541, ${\rho}$=.016) levels of the experimental group decreased after Dan Jeon Breathing compared to those of the control group. The difference in fatigue level was statistically insignificant (Z=-1.871, ${\rho}$=.061), though. From the above results, it was verified that Dan Jeon Breathing could be used as nursing intervention for hemodialysis patients to mitigate their depression and anxiety.

To evaluate the feasibility of electrodialysis for ammonia nitrogen removal from wastewater, the effects of operating parameters such as diluate concentration, applied voltage and flow rate on the removal of ammonia nitrogen were experimentally estimated. The removal rate was evaluated by measuring the elapsed time for ammonia nitrogen concentration of diluate to reach 20 mg/L. Limiting current density (LCD) linearly increased with ammonia nitrogen concentration and flow rate. The elapsed time was linearly proportional to initial concentration of diluate. Due to relatively large equivalent ion conductivity and ion mobility of ammonia nitrogen, the removal rate increased consistently with flow rate. Increase in the applied voltage gave positive effect to removal rate. From the operation of the electrodialysis module used in this research, the flow rate of 3.2 L/min and 80~90% of applied voltage for LCD are recommended as the optimum operating condition for the removal from high concentrate ammonia nitrogen solution.

A guideline for determining the optimal catheter length according to the patient's physique during tunnel-type dialysis catheter insertion used in renal failure patients is presented, and the maintenance of the function of the dialysis catheter is evaluated. From October 1, 2015 to February 31, 2016, a total of 110 (male : female = 73 : 37) patients who underwent tunnel-type dialysis catheterization performed at our hospital were treated without using guidelines. The group was divided into A group, and the group treated using the guideline into B group. Results were analyzed statistically using SPSS 20.0. As a result of the dialysis catheter insertion procedure according to the use of guidelines, the function maintenance rate of group A was 81.8%, and the function maintenance rate of group B was 96.3%. In the case of tunnel dialysis catheter procedure, the function maintenance effect was statistically significant in the group treated using the guideline compared to the group not using it (p<0.05). It can be said that it is more effective when information on the patient's underlying disease is reflected in addition to the use of guidelines.
