The concepts of 'sustainable development', 'sustainable construction' and 'green building' have been elevated to priority levels in all types and phases of construction project development worldwide. Consultants and contractors are now required to seriously consider the impact of their operations on the natural environment and the society, and consequently adopt sustainable construction practices in the development process to minimize and mitigate the negative impacts of their activities. However, existing sustainability rating tools apply to the design, post-construction and operation phases of a building; no tool exists for the rating of the performance of the contractor or the project team at the construction phase. This study aimed to develop a model for evaluating the sustainability of construction operations, drawing on the global best practice standards on sustainability. Practical applications of the model were carried out through case studies to evaluate the performances of fifteen construction firms in New Zealand. The developed model and the outcomes of the case studies were presented, including potential areas of weaknesses, strengths, constraints to achievement or adoption of sustainable construction practices and areas for improvement in the operations of the firms. The successful application of the developed model in practice shows its usefulness and ease of application. It is therefore recommended for adoption as a simple but effective system for measuring and reporting on sustainability performance or sustainability of construction operations of firms in New Zealand and elsewhere.

This paper proposes a block-based self-organizing time-division multiple access (BSO-TDMA) protocol for very high frequency (VHF) data exchange system (VDES) in shipborne ad-hoc networks (SANETs). The BSO-TDMA reduces the collisions caused by the simultaneous transmission of automatic identification system (AIS) messages by uniformly allocating channel resources using a block-wise frame. For this purpose, the BSO-TDMA includes two functional operations: (1) frame configuration and (2) slot allocation. The first operation consists of block division and block selection. A frame is divided into multiple blocks, each consisting of fixed-size subblocks, by using the reporting interval (RI) of the ship. Then, the ship selects one of the subblocks within a block by considering the number of occupied slots for each subblock. The second operation allocates the slots within the selected subblock for transmitting AIS messages. First, one of the unoccupied slots within the selected subblock is allocated for the periodic transmission of position reports. Next, to transmit various types of AIS messages, an unoccupied slot is randomly selected from candidate slots located around the previously allocated slot. Experimental simulations are conducted to evaluate the performance of BSO-TDMA. The results show that BSO-TDMA has better performance than that of the existing SOTDMA.

Purpose: Fire response education is critical for healthcare providers working in hospitals to ensure a safe environment for patients and staff. However, a comprehensive review that thoroughly examines the contents, methodologies, and outcomes of fire response education in hospitals is currently lacking. Methods: We conducted a scoping review by adhering to the framework proposed by Arksey and O'Malley. We searched five electronic databases for literature published after 1990, using the key categories of "hospitals," "fires," and "education." As a result, we identified 15 relevant articles that met our inclusion criteria for the review. Results: Of the 15 articles, 12 had adopted a quasi-experimental design and the remaining 3 had employed a true experimental design. The majority of these studies (11 out of 15) were conducted in the United States, with 4 studies forming committees or teams dedicated to education. Simulation methods were used in 13 studies, while 2 studies had employed a combination of methods. All studies focused on first-response procedures based on RACE (Rescue, Alarm, Contain, Extinguish/Evacuation). Outcome measures included the learners' overall experience, performance in the educational settings, and performance in the field, with all studies reporting positive results following the educational interventions. Conclusion: Our review highlights the importance of multi-professional and multi-departmental educational strategies based on institutional-level initiatives for healthcare providers to create a safe hospital environment.

Purpose: The purpose of this study was to identify the relationship between the satisfaction with clinical practice and clinical performance ability by types of self-directed learning ability of nursing students. Methods: This was a triangular study that was conducted to understand clinical performance ability. The subjects were 260 junior and senior students from a university in P city. The data were collected from April 22 to December 30, 2015. Data were collected by Q-card, Q-block an assessment tool, a structured self-reporting survey and a questionnaire. Results: We classified the self-directed learning abilities into four types: Type 1: a self-reflective person; Type 2: a person who prepares for the future; Type 3: a person with a sense of responsibility and obligation; and Type 4: an enthusiastic learner. We found that clinical performance ability was higher for Type 4 than Type 3. We found that clinical performance satisfaction with clinical practice was also higher for the Type 4 individual than a Type 3 person. Conclusion: To improve students' clinical performance ability, we need plans and support to lead students toward becoming an 'enthusiastic learner' type of person with self-directed learning ability. It is necessary to increase students' satisfaction with clinical practice.

Purpose: The purpose of this paper is to derive implication on the adoption of PROMs (Patient-Reported Outcome Measures) to improve quality of care in South Korea. With this purpose, the paper examines the status of PROMs in South Korea and other countries including OECD's PaRIS (Patient Reported Indicators Survey) initiative, and reviews policy cases that have adopted PROMs to improve performance of healthcare system. Methods: We conducted literature review on OECD reports on PaRIS, peer-reviewed journals, and information from the websites of relevant institutions such as ICHOM, NQF and OECD. Results: To identify healthcare services of best values and support patient-centered health system, OECD has initiated PaRIS which develops, collects and analyzes patient-reported indicators for cross-countries comparison. PaRIS is implemented on two work streams: 1) collect, validate and standardize PROMs in the areas where patient-reported indicators already exist such as breast cancers, hip and knee replacement, and mental conditions, 2) develop a new international survey on multiple chronic conditions. Countries like England, U.S., Sweden and Netherlands use PROMs for measuring performance of hospitals and performance evaluation at the national level, and provide the financial incentives for reporting PROMs. Conclusions: The use of PROMs can support the current policy agenda that is the patient-centered healthcare system which has been emphasized to reinforce the primary and the community-based care. For the use of PROMs, it is recommended to actively participate in PaRIS initiative by OECD, select appropriate instruments for PROMs, and continue on standardization of them. This will assure patients' involvement in improving health system performance, systemize information generated in the process of adopting PROMs, and develop a system to evaluate performance.

Objective: To investigate the concordance of three international guidelines: the Korean Thyroid Association/Korean Society of Thyroid Radiology, American Thyroid Association, and American College of Radiology for thyroid nodules classified by ultrasonography (US) and the diagnostic performance of simulated size criteria for malignant biopsies. Materials and Methods: A total of 2586 thyroid nodules (≥ 1 cm) were collected from two multicenter study datasets. The classifications of the thyroid nodules were based on three different guidelines according to US categories for malignancy risk, and the concordance rate between the different guidelines was calculated for the classified nodules. In addition, the diagnostic performance of criteria related to four different simulated biopsy sizes was evaluated. Results: The concordance rate of nodules classified as high- or intermediate-suspicion was high (84.1-100%), but low-suspicion or mildly-suspicious nodules exhibited relatively low concordance (63.8-83.8%) between the three guidelines. The differences in sensitivity, specificity, and accuracy between the guidelines were 0.7-19.8%, 0-40.9%, and 0.1-30.5%, respectively, when the original biopsy criteria were applied. The differences decreased to 0-5.9%, 0-10.9%, and 0.1-8.2%, respectively, when simulated, similar biopsy size criteria were applied. The unnecessary biopsy rate calculated with the original criteria (0-33.8%), decreased with the simulated biopsy size criteria (0-8.7%). Conclusion: We found a high concordance between the three guidelines for high- or intermediate-suspicion nodules, and the diagnostic performance of the biopsy criteria was approximately equivalent for each simulated size criterion. The difference in diagnostic performance between the three guidelines is mostly influenced by the various size thresholds for biopsies.

Objective: The timed up and go (TUG) test is method used to determine the functional mobility of persons with stroke. Its reliability, validity, reaction rate, fall prediction, and psychological characteristics concerning ambulation ability have been validated. However, the relationship between TUG performance and community ambulation ability is unclear. The purpose of this study was to investigate whether the TUG performance time could indicate community ambulation levels (CAL) differentially in persons with chronic stroke. Design: Cross-sectional study. Methods: Eighty-seven stroke patients had participated in this study. Based on the self-reporting survey results on the difficulties experienced when walking outdoors, the subjects were divided into the independent community ambulation (ICA) group (n=35) and the dependent community ambulation group (n=52). Based on the area under the curve (AUC), the discrimination validity of the TUG performance time was calculated for classifying CAL. The Binomial Logistic Regression Model was utilized to produce the likelihood ratio of selected TUG cut-off values for the distinguishing of community ambulation ability. Results: The selected TUG cut-off values and the area under the curve were <14.87 seconds (AUC=0.871, 95% confidence interval=0.797-0.945), representing a mid-level accuracy. Concerning the likelihood ratio of the selected TUG cut-off value, it was found that the group with TUG performance times shorter than 14.87 seconds showed a 2.889 times higher probability of ICA than those with a TUG score of 14.87 seconds or longer (p<0.05). Conclusions: The TUG can be viewed as an assessment tool that is capable of classifying CAL.

This descriptive comparative study was conducted to compare the relationships among self-esteem, self-efficacy, perceived health status and the performance of health promoting lifestyles for nursing and non-nursing students. The sample consisted of 246 nursing students and 166 non-nursing students at an evening class of junior college in T city. The data was collected by a self reporting questionnaire from March 2 to March 17, 1997 and analyzed by SPSS Win. 7.0 program for frequency, mean, percentage, t -test, ANOVA, and a Pearson correlation coefficient. The results of this study are summarized as follows: 1. The results of the comparison between the two groups was not significantly different for self esteem and perceived health status, but significantly different for self-efficacy. Nursing students had higher scores on self -efficacy than non-nursing students(t=4.621. p<.05). 2. There was a statistically significant difference between the two groups concerning a health promoting lifestyle. Nursing students ($157.73{\pm}20.26$) had higher scores on total health promotion as well as its 8 subscales than non -nursing students ($048.15{\pm}21.51$,), (t=21.074, p<.001). On subscales, nursing students had the highest score in sanitary life(3.22) and the lowest score in professional health maintenance(1.54). Non -nursing students had the highest score in harmonious relationships(3.10) and the lowest score in professional health maintenance (1.48). 3. Performance in a health promoting lifestyle was significantly correlated with such demographic variables as age and grade for nursing students, and types of dwelling for non -nursing students. 4. Perceptions of good health have been positively correlated with health promoting lifestyles. Those persons who rated their health as good showed the highest score, followed by excellent ,average, poor in that order. 5. Performance in health promoting lifestyles was significantly correlated with self-esteem, self-efficacy and, perceived health status. The most important factor that affect performance in health promoting lifestyles was self -efficacy.

This study was designed to identify the performance of occupational health services of 37 industries located in Kyung in area. The data was collected by a structured questionnaire developed by the Academic society of Community Nursing. This analysis had two factors, one was related to six of the industries, and the other was the actual assignment procedures of the health team members. This study was undertaken from December 4, 1992 to January 21, 1993. The results of the study were as follows: 1. The study group was primarily manufacturing industries which employed 300-1,000 employees. 2. The actual assignment state of occupation health team members with the exception of nurses was not kept to the regulations of the industrial safety health law. 3. The following was the analysis of the performance of occupational health services with two factors: 1). The larger the size of the six industries, the more the performance of health education, health assessment, and health screening. 2) The actual. practice of occupational health team members working environmental measurement, was more frequently performed by a nurse other than health team members together. 4. 1) The subscription rate of the laborers for primary health screening was 94%, and of these 10% had the need of secondary health screening. As a results of the secondary health screening the degrees were 'A' 45%, 'C' 92%, 'R' 21%. Of these degrees 'C', 'R' 4% were follow up cases. 2) 43% of laborers needed special health screening and .of these the subscription rate was 99%. The main item of the special health screening was physical factors. After the special health screening 46% required .follow up, 30% required medical treatment, only reporting 18%, change work 8%, suspension from work place 2%.
