  • Purpose: The purpose of this study was to develop the Self-Care Non-adherence Risk Assessment Scale (SCNRAS) for patients with chronic illness in South Korea. Methods: This study was conducted from April to July, 2020 and utilized a convenience sampling method to recruit 336 patients with chronic illness from three hospitals located in South Korea. The content, factorial structure, item-convergent/discriminant validity, convergent validity, internal consistency reliability, and test-retest reliability of the scale were evaluated. The data were analyzed using exploratory and confirmatory factor analyses, Pearson's correlation coefficient, Cronbach's α, and intra-class correlation coefficient. Results: The exploratory and confirmatory factor analyses yielded six-factors. Convergent validity was demonstrated using measures of defining issues. Internal consistency reliability and test-retest reliability were found to be acceptable, as indicated by a Cronbach's α of .65~.81 and an intra-class correlation coefficient of .93~.98. The Self-Care Non-adherence Risk Assessment Scale for patients with chronic illness is a new instrument that comprehensively measures the knowledge, skill, physical function status, access to health care, social support, motivation, and confidence. It comprises 18 items scored on a 5-point Likert scale. The validity and reliability of the scale were verified. Conclusion: The scale developed through this study is expected to screen those who need nursing intervention early by predicting the self-care non-adherence risk group.

  • A study was carried out to establish a detection method for irradiated black pepper using amylograph characteristics. The maximum viscosity, viscosity at $93^{\circ}C$, viscosity after 15 min at $93^{\circ}C$, viscosity at $45^{\circ}C$, viscosity after 30 min at $45^{\circ}C$, and viscosity after 60 min at $45^{\circ}C$ decreased with increasing irradiation doses, but initial pasting temperatures, maximum viscosity temperatures, breakdown, setback, and consistency did not show great changes. The high correlation coefficients $(R^2>0.97)$ were shown between irradiation doses and amylograph characteristics except for breakdown $(R^2>0.75)$, setback $(R^2>0.88)$ and consistency $(R^2>0.31)$. These results suggest that detection of irradiated black pepper is possible using amylograph characteristics.

  • Percent dormant root and percent missing root were investigated in ginseng (Panax ginseng) plantations and correlated with soil chemical characteristics. Percent dormant root showed no consistency with root age and significant positive correlation with percent missing root in many cases. Percent dormant root showed significant positive correlation with available phosphorus and phosphorus-moisture ratio in soils. Percent missing root showed significant negative correlation with moisture and calcium in soil and positive one with phosphorus - moisture ratio. Above results strongly suggest that excess phosphorus and water stress are the common causes of dormancy and missing of root.

  • Recently, many on-line approaches to instrument channel surveillance (drift monitoring and fault detection) have been reported worldwide. On-line monitoring (OLM) method evaluates instrument channel performance by assessing its consistency with other plant indications through parametric or non-parametric models. The heart of an OLM system is the model giving an estimate of the true process parameter value against individual measurements. This model gives process parameter estimate calculated as a function of other plant measurements which can be used to identify small sensor drifts that would require the sensor to be manually calibrated or replaced. This paper describes an improvement of auto-associative kernel regression by introducing a correlation coefficient weighting on kernel distances. The prediction performance of the developed method is compared with conventional auto-associative kernel regression.

  • Obvious vortex induced vibration (VIV) was observed during section model wind tunnel tests for a single main cable suspension bridge. An optimized section configuration was found for mitigating excessive amplitude of vibration which is much larger than the one prescribed by Chinese code. In order to verify the maximum amplitude of VIV for optimized girder, a full bridge aeroelastic model wind tunnel test was carried out. The differences between section and full aeroelastic model testing results were discussed. The maximum amplitude derived from section model tests was first interpreted into prototype with a linear VIV approach by considering partial or imperfect correlation of vortex-induced aerodynamic force along span based on Scanlan's semi-empirical linear model. A good consistency between section model and full bridge model was found only by considering the correlation of vortex-induced force along span.

  • The issue of climate change, which calls for urgent and improved action by countries around the world, requires cooperation from the international community. Therefore, consistency among various policies on climate change is particularly important. This study analyzes the relationship between the implementation of SDGs and the scale of assistance in the field of climate change in order to see if there is consistency between domestic policy and aid policy to address climate change issues. An analysis of the correlation between the indices related to the domestic implementation of SDGs and ODA amounts in the field of climate change by OECD countries was conducted. As a result, there is a significant negative correlation between imported CO2 emissions and the portion of climate change ODA. On the other hand, the amount of CO2 emissions embodied in fossil fuel export is significantly positively correlated with the portion of ODA for climate change. Consistency between domestic and aid policies of OECD countries in the field of climate change is not sufficiently ensured, and climate change, the cross-cutting issue, is not being pursued in a consistent direction across national policy.

  • The application of unmanned aerial vehicles (UAVs) has recently attracted considerable interest in various areas. A three-dimensional multiple-input multiple-output concentric two-hemisphere model is proposed to characterize the scattering environment around a vehicle in an urban UAV-to-vehicle communication scenario. Multipath components of the model consisted of lineof-sight and single-bounced components. This study focused on the key parameters that determine the scatterer distribution. A time-variant process was used to analyze the nonstationarity of the proposed model. Vital statistical properties, such as the space-time-frequency correlation function, Doppler power spectral density, level-crossing rate, average fade duration, and channel capacity, were derived and analyzed. The results indicated that with an increase in the maximum scatter radius, the time correlation and level-crossing rate decreased, the frequency correlation function had a faster downward trend, and average fade duration increased. In addition, with the increase of concentration parameter, the time correlation, space correlation, and level-crossing rate increased, average fade duration decreased, and Doppler power spectral density became flatter. The proposed model was compared with current geometry-based stochastic models (GBSMs) and showed good consistency. In addition, we verified the nonstationarity in the temporal and spatial domains of the proposed model. These conclusions can be used as references in the design of more reasonable communication systems.
