J-R curve tests were performed on 1T compact specimens of SA516 Gr. 70 carbon steels under reverse cyclic loading. A Direct-Current Potential Drop (DCPD) method, one of the nondestructive techniques to detect flaw of structure, is being increasingly used for monitoring crack initiation and stable crack growth in typical fracture mechanics specimens for J-R testing. In many aspects this method is simpler than the unloading compliance method. The objective of this paper is to evaluate the J-R Curve according to the crack length measurement techniques under reverse cyclic loading. In order to prove the reliability and repeatability of the DCPD method, the crack length measured by using DCPD method was compared to one determined from unloading compliance. Consequently, this DCPD method correlated well with J-R curves and crack extension measurements determined from unloading compliance method.

Objectives: In Indonesia, 61 million adults smoked in 2018, and 59 million were exposed to secondhand smoke at offices or restaurants in 2011. The Presidential Decree 109/2012 encouraged local governments to implement a smoke-free policy (SFP), and the city of Jayapura enacted a local bill (1/2015) to that effect in 2015. This study aimed to evaluate compliance with this bill and to explore challenges in implementing it. Methods: We conducted a mixed-methods study. Quantitatively, we assessed compliance of facilities with 6 criteria (per the bill): the presence of signage, the lack of smoking activity, the lack of sale of tobacco, the lack of tobacco advertisements, the lack of cigarette smoke, and the lack of ashtrays. We surveyed 192 facilities, including health facilities, educational facilities, places of worship, government offices, and indoor and outdoor public facilities. Qualitatively, we explored challenges in implementation by interviewing 19 informants (government officers, students, and community members). Results: The rate of compliance with all 6 criteria was 17% overall, ranging from 0% at outdoor public facilities to 50% at health facilities. Spatial patterning was absent, as shown by similar compliance rates for SFP facilities within a 1-km boundary around the provincial and city health offices compared to those outside the boundary. Implementation challenges included (1) a limited budget for enforcement, (2) a lack of support from local non-governmental organizations and universities, (3) a lack of public awareness at the facilities themselves, and (4) a lack of examples set by local leaders. Conclusions: Overall compliance was low in Jayapura due to many challenges. This information provides lessons regarding tobacco control policy in underdeveloped areas far from the central government.

Purpose: This study was to develop and evaluate an individualized education program based on self-efficacy for patients with kidney transplantation in Korea. Methods: A nonequivalent control group pretest-posttest design was used. The participants consisted of 43 patients who underwent kidney transplants at one hospital in Seoul, from July 2012 to April 2013. The experimental group received an individualized education based on self-efficacy in the hospital and follow-up telephone consultation in the 2nd and 3rd week after discharge. The control group received a routine discharge education. Knowledge, self-efficacy, and compliance related to kidney transplant were measured and analyzed by frequency, average, Mann-Whitney U test, Fisher's exact test, independent t-test, and ${\chi}^2$-test using SPSS WIN 20.0. Results: Significant differences were found in self-efficacy between the experimental group and the control group. But no significant differences were found in knowledge and compliance between two groups. The scores of several items on monitoring health status in compliance were higher in the experimental group than those of the control group. Conclusion: The results of this study demonstrate the fact that an education program based in self-efficacy for patients with kidney transplant would be effective in improving self-efficacy and the ability to monitor their health status.

Objectives: The nutritional status of cancer patients undergoing chemotherapy is closely related to the compliance of nutrition education. However, as chemotherapy is conducted repeatedly, compliance with nutrition management is lowered, leading to malnutrition. Malnutrition is related directly to the quality of life after surgery in cancer patients. Therefore, this study examined the factors related to compliance with nutrition management during chemotherapy. Methods: In this study, five subjects with colorectal cancer undergoing adjuvant chemotherapy were interviewed in-depth using the Giorgi study method. The contents of the nutrition education visits and in-depth interviews were transcribed in the language of the subject after recording, and the appropriateness of the data was improved by reflecting the subject's actions and facial expressions. Results: After conducting the in-depth interviews for each subject, the experience of the subject's diet and adjuvant chemotherapy was drawn into two domains, six elements, and 26 sub-elements. In the cognitive domain, the patients experienced physical and psychological changes, and the need for nutrition management was recognized by analyzing the dietary causes of the diseases. In the domain of practice, a knowing-doing gap was formed, unlike the patient's will. Factors that inhibited compliance with nutritional management included digestive problems, sensory changes, loss of appetite, and social interaction stress. Conclusions: Dietary management is very important for patients receiving periodic anticancer therapy, and step-by-step training and personal monitoring based on the chemotherapy order is necessary to maintain the patient's will and social and environmental support.

Purpose: This study aimed to identify the factors affecting compliance with personal protective equipment (PPE) use among medical device reprocessing staff. Methods: This descriptive cross-sectional study included 163 cleaning staff members from ten general hospitals in Seoul and Gyeonggi. Data were collected using self-report questionnaires administered between July and September 2023. Analysis included t-tests, ANOVA, Pearson's correlation coefficient, Bonferroni correction, and multiple regression, conducted using SAS ver.9.4. Results: Statistically significant differences in compliance with PPE were found based on department and exposure to contamination within six months (t=-2.82, p=.007). Attitudes toward PPE (r=.22, p=.006) and awareness of the safety climate (r=.22, p=.006) showed a statistically significant positive correlation with PPE compliance. Factors influencing use of personal protective equipment by cleaning staff during medical device reprocessing were department, compliance with PPE, and awareness of the safety climate. The explanatory power of these factors was 58.0%. Conclusion: Improving PPE compliance and creating a safe cleaning environment entails fostering a supportive safety climate. Additionally, regular training that takes into consideration the characteristics of the cleaning staff, alongside continuous monitoring, is required.

This paper reviews studies on the types and functions of oil sensors used for machine condition monitoring. Machine condition monitoring is essential for maintaining the reliability of machines and can help avoid catastrophic failures while ensuring the safety and longevity of operation. Machine condition monitoring involves several components, such as compliance monitoring, structural monitoring, thermography, non-destructive testing, and noise and vibration monitoring. Real-time monitoring with oil analysis is also utilized in various industries, such as manufacturing, aerospace, and power plants. The three main methods of oil analysis are off-line, in-line, and on-line techniques. The on-line method is the most popular among these three because it reduces human error during oil sampling, prevents incipient machine failure, reduces the total maintenance cost, and does not need complicated setup or skilled analysts. This method has two advantages over the other two monitoring methods. First, fault conditions can be noticed at the early stages via detection of wear particles using wear particle sensors; therefore, it provides early warning in the failure process. Second, it is convenient and effective for diagnosing data regardless of the measurement time. Real-time condition monitoring with oil analysis uses various oil sensors to diagnose the machine and oil statuses; further, integrated oil sensors can be used to measure several properties simultaneously.

A real-time wireless monitoring and analysis methods using the wearable PPG sensor to estimate cardiovascular condition is studied for ubiquitous healthcare service. A small size and low-power consuming wearable photoplethysmogram (PPG) sensor is designed as a wrist type device and connected with the IP node assigned its own IPv6 address. The measured PPG waveform in the IP node is collected and transferred to a central server PC through the IP-enabled wireless network for storage and analysis purposes. A monitoring and analysis program is designed to process the accelerated plethysmogram (APG) waveform by applying the second order derivatives to analyze systolic waves as well as heart rate variability analysis from the measured PPG waveform. From our results, the features of cardiovascular condition from individual's PPG waveform and estimation of vascular compliance by the comparison of APG-aging index (AI) and ratio of LF/HF are demonstrated.

Acute aquatic toxicity of effluents discharged from five dyeing plants in Gyeong-gi province were evaluated to assess whether the current Korean water quality standards(KWQS) could protect aquatic life. Chemical analyses of all parameters regulated under KWQS, except for E-coli, were also carried out to determine regulation compliance of the samples. All the effluent samples were satisfied with KWQS except for the color in only one sample. In acute Daphnia magna toxicity tests, significant mortality was observed in one of five samples and EC50 was 12.1%(95% confidence interval 9.1-16.2), which was in compliance with KWQS. The result of the Microtox assay indicated that acute microbial toxicity existed in effluents from three out of five plants, two of which were in compliance with KWQS. The agreement between regulation compliance of chemical concentrations of effluent and observed toxicity from various biological toxicity tests was very poor to fair (kappa = 0.194~0.250). The data presented suggest that exposure to dyeing wastewater which were in compliance with Korean water quality standards may not be safe to aquatic biota, and multiple tropical levels should be considered in aquatic toxicity monitoring of dyeing industry.

Purpose: The main purpose of this study was to examine the effectiveness of a standardized telephone monitoring intervention in addressing the symptom experience and improving self-management ability in patients with heart failure. Methods: A non-equivalent control group pre-post test design was used. There were 17 patients in the experimental group, and 16 in the control group. According to the protocol, patients in the experimental group received 15 to 30 minute-telephone monitoring four times, once a week for 4 weeks. Data were analyzed by ${\chi}^2$-test, Mann-Whitney U test. Results: 1) The experimental group showed a significant increase in compliance with self-management compared to the control group. 2) There was a significant decrease in degree for 3 symptoms(DOE, PND, & continuing fatigue) in the experimental group, after telephone monitoring. However, the experimental group did not show significant decrease in the degree of the total symptom experiences. Conclusions: The results of this study provide evidence that standardized telephone monitoring is effective in relieving symptom experience and improving self-management in patients with heart failure over the course of telephone monitoring.
