Purpose: Vital sign are used to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery. Researchers are using vital sign data and AI(artificial intelligence) to manage a variety of diseases and predict mortality. In order to analyze vital sign data using AI, it is important to select and extract vital sign data suitable for research purposes. Methods: We developed a method to visualize vital sign and early warning scores by processing retrospective vital sign data collected from EMR(electronic medical records) and patient monitoring devices. The vital sign data used for development were obtained using the open EMR big data MIMIC-III and the wearable patient monitoring device(CareTaker). Data processing and visualization were developed using Python. We used the development results with machine learning to process the prediction of mortality in ICU patients. Results: We calculated NEWS(National Early Warning Score) to understand the patient's condition. Vital sign data with different measurement times and frequencies were sampled at equal time intervals, and missing data were interpolated to reconstruct data. The normal and abnormal states of vital sign were visualized as color-coded graphs. Mortality prediction result with processed data and machine learning was AUC of 0.892. Conclusion: This visualization method will help researchers to easily understand a patient's vital sign status over time and extract the necessary data.

The number of accidents in school zone is decreasing than before with the introduction of strengthening traffic safety policy since January 2011, but the danger still exists. The School zone sign is widely known to have much effect in protecting children from risks of traffic accidents, but design improvement is being demanded to improve a sense of safety and legibility of safety signs in School zone due to the lack of understanding on the safety signs in crosswalk and School zone. This study analyzed differences in shape and color of existing safety signs through a case analysis of traffic developed countries as America, England, Japan, and Germany and suggested improvement plans for drivers to clearly perceive the school zone. For improvement methods, this study suggested the importance of delivering definite and unified warning message for school zone to drivers by using indication sign and caution sign together, and to use yellow, a safety color, and to unify the safety sign into triangle shape that symbolizes warning and caution to conform the international standards. Actual design production and experiment through improvement plans are needed in the future, and it is expected to secure safety of children and to provide international standardization of safety signs in school zone.

In the event of a major accident such as an explosion in a refinery or a petrochemical plant, it has caused a serious loss of life and property and has had a great impact on the insurance market. In the case of catastrophic incidents occurring in process industries such as refinery and petrochemical plants, only the proximate causes of loss have been drawn and studied from inspectors or claims adjustors responsible for claims of property insurers, incident cause investigators, and national forensic service workers. However, it has not been done well for conducting root cause analysis (RCA) and identifying the factors that contributed to the failure and establishing preventive measures before leading to chemical plant's catastrophic incidents. In this study, the criteria of warning signs on CCPS catastrophic incident waning sign self-assessment tool which was derived through the RCA method and the contribution factor analysis method using the swiss cheese model principle has been reviewed first. Secondly, in order to determine the major incident warning signs in an actual chemical plant, 614 recommendations which have been issued during last the 17 years by loss control engineers of global reinsurers were analyzed. Finally, in order to facilitate the assessment index for catastrophic incident warning signs, the criteria for the catastrophic incident warning sign index at chemical plants were grouped by type and classified into upper category and lower category. Then, a catastrophic incident warning sign index for a chemical plant was developed using the weighted values of each category derived by applying the analytic hierarchy process (pairwise comparison method) through a questionnaire answered by relevant experts of the chemical plant. It is expected that the final 'assessment index for catastrophic incident warning signs' can be utilized by the refinery and petrochemical plant's internal as well as external auditors to assess vulnerability levels related to incident warning signs, and identify the elements of incident warning signs that need to be tracked and managed to prevent the occurrence of serious incidents in the future.

In this paper, a pattern spectrum component function is introduced for an oriented shape analysis and its properties are discussed. It can represent directional information of shape more precisely than the conventional oriented pattern spectrum. An adaptive distance function between two pattern spectrum component functions is presented to recognize different shapes in noise. As a practical application, the pattern spectrum component function is applied to warning traffic sign recognitions utilizing the adaptive distance functions. Favorable results are obtained compared to the oriented pattern spectrum.

This study is a descriptive study conducted to investigate the effect of smoking cigarette sign sold in Korea on the smoking cessation effects and to use it as a basis for future smoking cessation and health related health data. To this end, we surveyed 500 men and women over 20 years of age on the Internet Naver web using Naver form questionnaire for 10 days from October 1, 2018 using blogs and cafes. The analyzed data were analyzed by factor analysis, T-test and correlation using SPSS WIN20.0. The main findings were as follows: First, the cigarette warning picture harmful to human body had the biggest influence on the smoking cessation effect. Second, the smoking cessation effect had the highest correlation with the pre-question consciousness about the cigarette warning picture. This indicates that the cigarette pack warning is considered the most sensitive part of smokers. Based on the results of this paper, diversification of cigarette warning picture and regular replacement of warning picture are expected to provide useful basic data for suggesting practical measures to prevent smoking. do. Therefore, the smoking warning picture is widely promoted through the media and the media, which has a positive effect on the practice of quitting smoking to the public, and is also used as a basic data for the health policy for the health promotion of the public.

Purpose: The purpose of this research was to identify the relationships between stroke knowledge, health perception, exercise self-efficacy and stroke prevention behaviour and the factors influencing stroke prevention behaviour in middle-aged adults. Methods: A cross-sectional survey was conducted in 2 cities of Korea from May to July 2020, using structured questionnaire. The participants were 168 middle-aged adults without a history of stroke. Collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression with SPSS/WIN 25.0. Results: There was significant correlations among degree of stroke prevention behaviour, stroke knowledge about warning sign (r= .20, p= .010), health perception (r= .35, p< .001) and exercise self-efficacy (r= .43, p< .001). The most important factor influencing stroke prevention behaviour was exercise self-efficacy (β= 0.38, p< .001), followed by health perception (β= 0.18, p= .008), body mass index (β= -0.17, p= .011), stroke knowledge about warning sign (β= 0.13, p= .045) in that order. These factors explained 37.7% of total variance in stroke prevention behaviour (F= 11.09, p< .001). Conclusion: The results of this study suggest that the development of nursing intervention for stroke prevention behaviour improvement is needed considering exercise self-efficacy and stroke knowledge.

Safety sign panel has been used in construction sites to assure the safety of the workers. Such safety panel can be categorized as 4 different signals, such as prohibition, warning, indication, and information. Each of the categorized item must follow lawful which is specifically designated for its own purposes, on its color and the shape. However, the color and shape of the safety sign panels that have been used in construction sites are not found to follow the suggested lawful requirement, and such differences are originated from safety merchandise production company or vendor, and construction company. In this study, samples of safety sign panels were obtained from various construction sites in Republic of Korea then the colors of such samples were measured, analyzed, and compared. According to the results, colors of the safety sign panels were out of the lawful requirement due to the aging and surface contamination of the safety sign panel. Frequent maintenance on the safety sign panel is therefore necessary. In addition, steel panels that were used in the construction sites were found to be unsuitable to meet the lawful requirements. In order to the color requirements on safety sign panel, it is recommended for Korea Occupational Safety and Health Agency to provide standard reference sample for each material used to produce safety sign panel, to distribute them to the producer and construction sites, and to supervise overall system.
