In this study, a MWCNT(multi-wall carbon nanotube) was added to polysulfone(PSf) support layer to improve flux of TFC(thin film composite) RO(reverse osmosis) membrane. Two different kinds of MWCNT were used. Surfaces of some MWCNTs were modified hydrophilically through acid treatment, while those of other MWCNTs were modified through heat treatment to maintain their hydrophobicity. MWCNT/PSf support layer was prepared by adding PSf to the NMP mixed solvent containing 0.1 wt% MWCNTs using a phase inversion method. The surface porosity of the MWCNT/PSf support increased by 42~46% while its surface pore size being maintained. The TFC RO membrane made of MWCNT/PSf support layer showed a 20% flux increase while its salt rejection characteristics is sustained. In addition, the MWCNT/PSf support layer has better mechanical stability than the PSf support layer, there resulting in an increased resistance of flux reduction due to physical pressure.

Background: Despite improved managements for acute respiratory distress syndrome (ARDS), its mortality remains high. Extracorporeal membrane oxygenation (ECMO) has emerged as the final option for the treatment of ARDS unresponsive to conventional measures. This study describes our experiences of venovenous ECMO support for the treatment of ARDS. Materials and Methods: Between 2007 and 2010, 56 patients (aged $56.6{\pm}13.4$ years, 43 males) received venovenous ECMO for the treatment of ARDS. The detailed clinical records were retrospectively reviewed. Results: Before the institution of ECMO support, 35 patients (55.4%) required nitric oxide inhalation, 35 patients (55.4%) received continuous renal replacement therapy, and 20 patients (35.7%) were in shock status. The median duration of ECMO support was 164 hours (range, 5 to 1,413 hours). 27 (48%) patients could be successfully weaned from ECMO. Of them, 7 (13%) survived to discharge. On logistic regression analysis, a requirement for higher inspiratory pressure before ECMO support was the only significant factor that could predict ECMO weaning failure. Conclusion: The outcome of venovenous ECMO support for the treatment of ARDS was suboptimal. Further improvements in outcomes should be made through the accumulation of experience and establishment of a standardized protocol for the management of ECMO.

Social support is regarded as a complex construct which has long been suggested to have direct and buffering effects on patients' wellbeing and emotional adjustment to cancer. Cross-sectional and prospective studies show a positive association between perceived social support and psychological adjustment following cancer treatment. Research findings suggest that the evidence for the relationship between social support and cancer progression is sufficiently strong. This report points out the importance of social support in cancer and provides recommendations for health care professionals.

Purpose: This study was to examine the food intake and family support of patients with Coronary Artery Disease(CAD). Methods: 90 hospitalized patients who received CAD medical treatment were randomly selected. The food intake frequency and family support instrument were utilized. Collected data was analyzed by SPSS/WIN 14.0: t-test, $x^2$-test and Pearson's correlation coefficient. Results: The mean score of food intake frequency was 5.65(total mean score 97.50) which was relatively healthy food intake based on the CAD treatment guidelines. Undesirable food intake items were fruit, fish, milk etc. The mean score of family support was 2.44(range: 1 - 4). Food intake showed a significant(p < .001) positive correlation with family support. There was significant difference(p < .05) on family support according to exercise. There was significant difference(p < .05) on LDL level, one of the CAD risk factors, between first admission patients and readmission patients. Conclusion: These findings suggest that nursing intervention education programs should be developed to appropriately care for CHD patients for needed changes.

Purpose: This study was conducted to investigate the effect of tuberculosis-related knowledge and family support on medication adherence in tuberculosis patients. Methods: The data were collected from 175 patients diagnosed with tuberculosis at three general hospitals located in two provincial cities in South Korea from September 1 to November 31, 2020. The 160 questionnaires were analyzed using IBM SPSS WIN 25.0. Results: The patients' average score for tuberculosis-related knowledge was 15.85±5.87 (out of 25), for family support it was 22.03±9.20 (out of 35), and for medication adherence it was 5.11±2.68 (out of 8). There were significant differences in tuberculosis-related knowledge, family support, and medication adherence according to patients' general characteristics and significant positive relationships among tuberculosis-related knowledge, family support, and medication adherence. Factors affecting patients' tuberculosis medication adherence were history of stopping the medication, the importance of treatment among tuberculosis-related knowledge and family support, and these factors could explain 78% of patients' taking tuberculosis drugs. Conclusion: It could be concluded that the importance of tuberculosis treatment and family support are very important for improving patients' rates of medication adherence. Therefore, medical staffs caring for tuberculosis patients need to manage patients' medication of tuberculosis drugs with continuous consultation.

A combined treatment system using multiple source water is becoming important as an alternative to conventional water supply for small-scale water systems. In this research, combined water treatment systems were investigated for simultaneous use of multi-source water including rainwater, ground water, river water, and reclaimed wastewater. A laboratory-scale system was developed to systematically compare various combinations of water treatment processes, including sand filtration, microfiltration (MF), granular activated carbon (GAC), and nanofiltration (NF). Results showed that the efficiency of combined water treatment systems was affected by the quality of feed waters. In addition, a simply approach based on the concept of linear combination was suggested to support a decision-making for the optimum water treatment systems with the consideration of final water quality.
