Purpose: The purpose of this study was to identify minimum datasets for ulcer assessment and to map the minimum datasets to paper-based nursing records for pressure ulcer care in homecare setting. Methods: To identify minimum datasets for pressure ulcer assessment, the authors reviewed four guidelines for pressure ulcer care. The content validity of the minimum datasets was assessed by three homecare nurse specialists. To map the minimum datasets to nursing records, the authors examined 107 pressure ulcer events derived from 45 pressure ulcer patients who received home nursing from two hospitals in Gyeonggi Province. Results: The minimum datasets for initial assessment were anatomical location, stage, size, tissue, exudate, condition of periwound skin, undermining, odor, and pain. 'Location' was recorded best, accounting for a complete recording rate of 98.1%. 'Exudate' and 'pain' showed the poorest record, accounting for 2.8% and 0%, respectively. The minimum datasets for progress assessment were wound size, tissue, and exudate, each accounted for 31.8%, 2.8%, and 4.7%, respectively. Conclusion: This study concluded that data on pressure ulcer assessment was not sufficient homecare and it can be improved by adopting minimum datasets as identified in this study.

This study aims to identify the work process of records managers under the Freedom of Information Act (FOI). In particular, it attempted to reveal the problems and difficulties that record managers encounter during FOI work. To do this, this study conducted in-depth interviews with 11 records managers who were in charge of records management and FOI work, and the accumulated data were subjectively analyzed. The study discussed the relationship between records management and FOI and emphasized the need for procedural improvements of the act to alleviate psychological pressure on records managers and help them focus more on the records management process itself.

Purpose: To demonstrate the importance of comprehensive skin observation as an effective intervention for pressure injury prevention in elderly long-term care hospital patients. Methods: The survey was conducted with 70 nursing staff members working at two long-term care hospitals with 200 beds or less in D city. Data were collected from October 16 to October 23, 2019 and analyzed using descriptive statistics, the chi-square test, and the independent t-test with the SPSS 25.0 program. Results: Nursing care knowledge for pressure injury was similar between the two groups. Conversely, nursing care performance for pressure injury degree of the nursing staff in the hospital using skin observation records performed better than those who did not (t=6.11, p<.001). Furthermore, comprehensive skin assessments in long-term care hospitals using skin observation records showed a lower incidence rate of pressure injury than that showed using general skin assessments (t=-5.28, p=.006). Conclusions: Comprehensive skin assessment is important for pressure injury prevention in elderly long-term care hospital patients. To implement this effectively, it is necessary to devise institutional regulations, guidelines, and systematic education programs.

Background: Although work absenteeism is in the focus of occupational health, longitudinal studies on organizational absenteeism records in hospital work are lacking. This longitudinal study tests time pressure and lack of time autonomy to be related to higher sickness absenteeism. Methods: Data was collected for 180 employees (45% nurses) of a Swiss hospital at baseline and at follow-up after 1 year. Absent times (hours per month) were received from the human resources department of the hospital. One-year follow-up of organizational absenteeism records were regressed on self-reported job satisfaction, time pressure, and time autonomy (i.e., control) at baseline. Results: A multivariate regression showed significant prediction of absenteeism by time pressure at baseline and time autonomy, indicating that a stress process is involved in some sickness absenteeism behavior. Job satisfaction and the interaction of time pressure and time autonomy did not predict sickness absenteeism. Conclusion: Results confirmed time pressure and time autonomy as limiting factors in healthcare and a key target in work redesign.

Subsurface pressure gauge has many advantages in measuring a wide range of wave spectra in coastal waters from wind waves to long waves. However, a shortcoming of the gauge is related to the difficulties in recovering surface wave spectra from subsurface pressure records. In this study, the effect of current on the pressure transfer function of the pressure gauge, and hence on the surface wave energy spectrum, was investigated by analyzing the subsurface pressure data based on the linear wave theory. For this purpose, laboratory experiments were carried out in a wave-current flume. Subsurface pressure records, as well as the surface elevation data, were obtained simultaneously under different wave and current conditions. Pressure transfer functions were obtained and compared with those estimated from the linear wave theory, both with and without inclusion of the current-effect. It was established that wave spectra obtained from subsurface pressure gauge were in closer agreement with those from surface wave gauge when current-effect on the pressure transfer function was taken into consideration for analysis.

The purpose of this study was to examine the statements characteristics of the pressure ulcer nursing record by natural langage processing and assess the prediction accuracy for each pressure ulcer stage. Nursing records related to pressure ulcer were analyzed using descriptive statistics, and word cloud generators (http://wordcloud.kr) were used to examine the characteristics of words in the pressure ulcer prevention nursing records. The accuracy ratio for the pressure ulcer stage was calculated using deep learning. As a result of the study, the second stage and the deep tissue injury suspected were 23.1% and 23.0%, respectively, and the most frequent key words were erythema, blisters, bark, area, and size. The stages with high prediction accuracy were in the order of stage 0, deep tissue injury suspected, and stage 2. These results suggest that it can be developed as a clinical decision support system available to practice for nurses at the pressure ulcer prevention care.

Purpose: The purpose of this study was to examine the accuracy of general nurses' assessments of pressure ulcers in hospitalized patients. Methods: A total of 129 nursing records of assessments on pressure ulcers were analyzed. Assessment records of pressure ulcers by general nurses were compared to those by Wound, Ostomy, Continence Nurses (WOCN) on the same pressure ulcers. A WOCN of a nursing unit was a nurse certified by the hospital after completion of a formal WOCN course and passing a cyber education course, both offered by the hospital. The formal WOCN course was taught by an internationally certified WOCN. The inter-rater reliability among WOCNs was 98.2%. General nurses in this study did not receive a structured pressure ulcer education. Results: The accuracy for nursing assessment of pressure ulcers by general nurses compared to WOCNs' were evaluated in various ways and resulted in as follows; the existence of pressure ulcer 91.4%, site of pressure ulcer 85.3%, stage of pressure ulcer 85.3%, Braden scale 36.3%, size of pressure ulcer 51.9~64.3%, details of pressure ulcer 0~100%. Conclusion: The structured education about pressure ulcer assessment is important to enhance the accuracy of pressure ulcer assessment of hospitalized patients by general nurses.

Evacuation performance, starting transient, and plume blowback at diffuser breakdown of a straight cylindrical supersonic exhaust diffuser with no externally supplied secondary flow are investigated. Pressure records in the transitional periods are measured by a small-scale cold-gas simulator. Flow-fields evolving in the diffuser-type ejector are solved by preconditioned Favre-averaged Navier-Stokes equations with a low-Reynolds number $k-{\varepsilon}$ turbulence model edited for turbulence compressibility effects. The present RANS method is properly validated with measured static wall pressure distributions and evacuation level at steady operation as well as the pressure records during the transition regime.

A System Identification method to develop parametric models linking free surface elevation and wave pressure is presented and two models are built allowing for either wave pressure or free surface elevation simulation. Linear, time invariant model structures with static nonlinearities are assumed and solutions are sought in a form of autoregressive model with extra input (ARX). An arbitrary chosen free-surface elevation and wave pressure dataset is used for estimation of the models, which are subsequently verified against datasets with similar pressure gauge depth but different free-surface elevation spectra due to different meteorological conditions. It is shown that free-surface simulation using System Identification methods can perform better than traditional linear transfer function derived from linear wave theory (LTF), while wave pressure simulation quality using presented methods is generally similar to that obtained with corrected LTF.

The records of field instrumentation, which have been performed on the pneumatic caisson used for substructure of the Youngjong Grand Bridge, were analyzed to investigate the ground contact pressure under rigid foundation of large pneumatic caisson embedded in various ground layers. During sinking the pneumatic caisson, the resisting force was mobilized against sinking the caisson at the contact area between bottom of the caisson and the ground. The resisting force could be measured by the reaction force gauges instrumented under the edge of bottom of the pneumatic caisson. And the ground contact pressure could be estimated by use of the measuring records of the resisting force. The ground contact pressure under rigid foundation of large pneumatic caisson shows concave distribution on bedrock, while convex distribution was shown in marine deposit soil layer as well as weathered rock layer. And, the ground contact pressure in various ground layers was distributed axis-symmetrically. The distribution shape of the ground contact pressure determined by the maximum pressure acting on foundation of the large pneumatic caisson showed good coincidence with the distribution shape proposed for rigid foundation by Kgler(1936) and Fang(1991).
