Purpose: This study examined the relationship between Knowledge of Life-sustaining Treatment Plans and Attitudes toward Withdrawal of Life-sustaining Treatment among nursing college students, and attempted to identify the mediating effect of Role Perception on Life-sustaining Treatment in that relationship. It is hoped that the findings will ultimately contribute to the development of active nursing strategies. Methods: The participants were 142 nursing college students in the third and fourth years of study who had experienced clinical practice at two universities in cities Y and C. Data were collected from November 1 to 30, 2019. For data analysis, SPSS for Windows version 22.0 was used to calculate descriptive statistics, the t-test, Pearson's correlation coefficients, and multiple regression. To analyze the mediating effect, the Baron and Kenny bootstrapping method was used. Results: Attitudes toward Withdrawal of Life-sustaining Treatment of nursing college students had a significant positive correlation with Knowledge of Life-sustaining Treatment Plans (r=0.34, P<0.001) and Role Perception on Life-sustaining Treatment (r=0.44, P<0.001). Role Perception on Life-sustaining Treatment partially mediated the relationship between Knowledge of Life-sustaining Treatment Plans and Attitudes toward Withdrawal of Life-sustaining Treatment (95% CI, 0.446~1.055). Conclusion: Based on the results of this study, improving nursing college students' Role Perception on Life-sustaining Treatment could be used as a coping strategy to establish positive Attitudes toward Withdrawal of Life-sustaining Treatment.

In this work, extensions to partial least squares (PLS) for wastewater treatment (WWT) process monitoring are discussed. Conventional data gathered by monitoring WWT systems are usually time varying, high dimensional, correlated and nonlinear, PLS has been shown to be an efficient approach in modeling and monitoring high dimensional and correlated data. To represent dynamic and nonlinear features of the data several kinds of dynamic nonlinear PLS (DNLPLS) models have been proposed. However, the complexity and ambiguity of the models make them unsuitable for WWT monitoring, Recently, dynamic fuzzy PLS (DFPLS) was proposed ...

Background: The Korean government introduced National Cancer Control Program and strengthening national health insurance coverage for cancer patients. Although many positive effects have been observed, there are also many concerns about cancer management such as patient concentration or time-to-treatment. Thus, we investigated the association between the time-to-treatment and survival of cancer patients, and compared regional differences by time trend. Methods: The data used in this study were national health insurance claims data that included patients diagnosed with lung cancer and received surgical treatment between 2005 and 2015. We conducted survival analysis with Cox proportional hazard model for the association between time-to-treatment and survival in lung cancer. Additionally, we compared the regional differences for time-to-treatment by time trend. Results: A total of 842 lung cancer patients were included, and 52.3% of lung cancer patients received surgical treatment within 30 days. Patients who received surgical treatment after 31 days had higher 5-year or 1-year mortality compared to treatment within 30 days (5-year: hazard ratio [HR], 1.566; 1-year: HR, 1.555; p<0.05). There were some regional differences for time-to-treatment, but it was generally reduced after 2010. Conclusion: Delayed surgical treatment after diagnosis can negatively affect patient outcomes in cancer treatment. To improve cancer control strategies, there are needed to analyze the healthcare delivery system for cancer care considering the severity and types of cancer.

Objectives This study was conducted to confirm anatomical information near the treatment areas of visceral chuna manual therapy and to secure stability and effectiveness during the treatment. Methods For 50 healthy adult men and women, a total of 13 ultrasound images were taken of the 7 treatment areas which are the representative treatment areas of visceral Chuna manual therapy. Results The treatment area of the bottom of the liver can be palpated around the right side ST19 and CV14. The treatment area of the gallbladder and the common bile duct can be palpated around the right side SP16 and ST20. The treatment area of the cardia and the pylorus can be palpated around the left side KI21, right side ST20, ST21, KI19, KI20, CV12, and CV13. The origin point of the mesentery root can be moved to the left and lower left from CV12 and can be palpated. The treatment area of the ileocecal valve and the cecum can be palpated around the right side SP14. The treatment area for the colic flexure can be palpated around the both side LR13. The treatment support point for the kidneys can be palpated around both side BL51. Conclusions It is thought that if the ultrasound image data from the meridians around the treatment site is used as an auxiliary, it will be more effective in terms of safety and effectiveness during the treatment of visceral Chuna manual therapy.

Multivariate analysis and batch monitoring on a pilot-scale sequencing batch reactor (SBR) are described for integrated wastewater treatment management system, where a batchwise multiway independent component analysis method (MICA) are used to extract meaningful hidden information from non-Gaussian wastewater treatment data. Three-way batch data of SBR are unfolded batch-wisely, and then a non-Gaussian multivariate monitoring method is used to capture the non-Gaussian characteristics of normal batches in biological wastewater treatment plant. It is successfully applied to an 80L SBR for biological wastewater treatment, which is characterized by a variety of error sources with non-Gaussian characteristics. The batchwise multivariate monitoring results of a pilot-scale SBR for integrated wastewater treatment management system showed more powerful monitoring performance on a WWTP application than the conventional method since it can extract non-Gaussian source signals which are independent and cross-correlation of variables.

It has a limitation to satisfy the phosphorus effluent criteria of 0.2 mg/L which will be reinforced from 2012 with the Biological Nutrient Removal (BNR) process. The chemical coagulation process has been operated in parallel with the biological treatment process for advanced treatment of phosphorous in the developed countries including Europe. However, the coagulation process has some disadvantages such as the desired goal may not be achieved without injecting the optimum dosage of the coagulant. This study developed the automatic control system to inject the optimum dosage of phosphorous coagulant into the coagulation process. The adopted coagulant was 10% Poly Aluminum Chloride (PAC) in this study. The automatic control system developed in this study was adopted for the treatment of the phosphorus from the effluent in SBR process. The automatic control system was composed of the data receiving part, the optimum coagulant dosage control part and the data transmit part. The result of the phosphorous advanced treatment of the SBR effluent using the automatic control system showed the removing efficiency over 95% consistently with the phosphorous concentration under 0.02 ~ 0.15 mg/L. The reproducibility analysis for checking the safety of automatic control system showed more than 95% correlation.

This Study includes the information of integrated discussion and economies of scale on local governments' sewerage treatment plant through translog function based on the reality reports of sewerage treatment plant operation published by Ministry of Environment and sewerage statistics data from 2005 to 2010. Based on analysis results from the data of 35 local governments in Jeollanamdo and Jeollabukdo, which are selected as pilot project areas of sewerage facility integration by Ministry of Environment and have low percent of sewered population, it shows the existence of economies of scale. The economies of scale on sewerage treatment show the loss of approximately 22,211 thousand ton/day in sewage treatment, it is 1.7 times compared to the average treatment amount of 35 local governments as of 2010. It means the economies of scale can be achieved by lowering operation cost along with large scale integration in installation, operation and maintenance due to the features of sewerage industry as one of network industry.
