Recently, owing to global warming, average summer temperatures are increasing and the number of hot days is increasing is increasing, which leads to an increase in heat stroke. In particular, outdoor workers directly exposed to the heat are at higher risk of heat stroke; therefore, preventing heat-related illnesses and managing safety have become important. Although various wearable devices have been developed to prevent heat stroke for outdoor workers, applying various sensors to the safety helmets that workers must wear is an excellent alternative. In this study, we developed a smart helmet that measures various vital signs of the wearer such as body temperature, heart rate, and sweat rate; external environmental signals such as temperature and humidity; and movement signals of the wearer such as roll and pitch angles. The smart helmet can acquire the various data by connecting with a smartphone application. Environmental data can check the status of heat wave advisory, and the individual vital signs can monitor the health of workers. In addition, we developed an algorithm that classifies the risk of heat-related illness as normal and abnormal by inputting a set of vital signs of the wearer using a support vector machine technique, which is a machine learning technique that allows for rapid binary classification with high reliability. Furthermore, the classified results suggest that the safety manager can supervise the prevention of heat stroke by receiving feedback from the control system.

PURPOSE. This study aimed to investigate whether the accuracy of intraoral scanners is influenced by different scanning strategies in an in vitro setting, through a systematic review and meta-analysis. MATERIALS AND METHODS. This review was conducted in accordance with the PRISMA 2020 standard. The following PICOS approach was used: population, tooth impressions; intervention, the use of intraoral scanners with scanning strategies different from the manufacturer's instructions; control, the use of intraoral scanners following the manufacturers' requirements; outcome, accuracy of intraoral scanners; type of studies, in vitro. A comprehensive literature search was conducted across various databases including Embase, SciELO, PubMed, Scopus, and Web of Science. The inclusion criteria were based on in vitro studies that reported the accuracy of digital impressions using intraoral scanners. Analysis was performed using Review Manager software (version 5.3.5; Cochrane Collaboration, Copenhagen, Denmark). Global comparisons were made using a standardized mean difference based on random-effect models, with a significance level of α = 0.05. RESULTS. The meta-analysis included 15 articles. Digital impression accuracy significantly improved under dry conditions (P < 0.001). Moreover, trueness and precision were enhanced when artificial landmarks were used (P ≤ 0.02) and when an S-shaped pattern was followed (P ≤ 0.01). However, the type of light used did not have a significant impact on the accuracy of the digital intraoral scanners (P ≥ 0.16). CONCLUSION. The accuracy of digital intraoral scanners can be enhanced by employing scanning processes using artificial landmarks and digital impressions under dry conditions.

Background: The compression therapy, which is the standard treatment for lymphedema patients, may be difficult to implement and contraindicated to some patients depending on their health condition. Objects: The purpose of this study is to investigate whether kinesiology taping (KT) can be used effectively and safely in the management of lymphedema as an alternative treatment through systematic review and meta-analysis. Methods: In February 2023, the literature was systematically collected through eight search engines with a combination of terms, 'lymphedema' and 'kinesiology taping.' We qualitatively analyzed the differences and safety of KT methods, and quantitatively meta-analyzed the effects of volume reduction in edema, range of motion (ROM), and pain improvement using Review Manager ver. 5. 4. To assess the risk of bias in the randomized controlled trial (RCT) studies, Risk of Bias was used. Results: A total of 616 articles searched and 20 studies were selected, including 12 RCTs and eight case studies. KT intervention could not replace multilayer compression bandage (MLB), but it demonstrated similar or better results compared to compression garment (CG), with reduced pain and improved intervention comfort. Studies reported skin adverse events ranging from 2.5% to 20.68%, with a total adverse event incidence of 7.7%. There was no significant difference in the application method of KT. As a result of the meta-analysis from the 8 RCTs, the KT intervention showed a mean difference (MD) of -7.18 with a 95% confidence interval (CI) [-12.64 to -1.72] in the volume change of lymphedema, while the pain difference was MD 0.82 with CI 95% [0.50 to 1.15], in comparison to the MLB and CG intervention. Conclusion: KT therapy led to a reduction in edema size, volume, pain, and improved ROM and quality of life. KT may be a viable option for lymphedema patients who have trouble applying traditional compression therapies.

Safety is not a service provided selectively by the country, and it is a basic right that human beings should enjoy. However, as the recent expansion of outsourcing due to the efficient corporate management, fatal accidents such as the Taean Power Plant where subcontractors are pinched on conveyors continued to occur. In addition, public safety concerns have been widespread as there are constant safety-related accidents in public institutions such as KTX trains derailing. As public institutions require safety as a top priority for management rather than profit, the government needs a leading role to enhance the level of private safety activities. The government announced the "Measures to strengthen the workplace safety of public institutions" and is promoting measures to protect the lives and safety of the people. The purpose of this study was to in-depth analysis of the accident and death situation in public institutions in the last 5 years from 2014 to 2018. A recognition survey was also conducted and the results were analyzed. As a result of the analysis of industrial accident death, it showed that the number of industrial accident deaths in public institutions was about 50 people per year, and it occupied about 6.1% of all industrial accidents. Following the government's public policy measures, positive changes as a result of the survey on awareness were detected in the order of rising safety awareness and participation of management (56.9%), safety and health organization and personnel composition (37.9%), and increasing safety awareness and participation of members (18.9%). However, the obstacles to the implementation of government measures were followings; 1) consciousness and lack of participation (42.1%), 2) indifference from other departments (35.1%), 3) absence, or lack of competency of safety manager (33.3%). In addition, safety investments and safety management of contractors and ordering works were analyzed to have remained largely unchanged even after the implementation of safety measures. Through this study, it is intended to provide basic data for strengthening the level and activities of safety in public institutions.

The purpose of this study was to obtain the basic data as a improvement method through the fact-revealing concerning the drinking water management of school and utilization of student. The problems of the research are as follows: First, to investigate status of management of drinking water by area and school. Second, to investigate student's utilization of drinking water by area and school. 1,400 students was selected at 45 elementary and middle-high schools located in Kang-won province, and this study was constituted of two questionnaires(for school's questionnaire and student's questionnaire). The results was analyse through the frequency analysis, $x^2$-test on the basis of the above research problem by SPSS program. The findings of this research are as follows; 1) The Management of School Drinking Water First, the source of school drinking water was mostly piped water. Inspection of water quality has been fulfilled under four times a year, in the other hands, from the result inspection, the schools which was given inadequate determination was 22.2%. Second, reservoir cleaning and hygiene inspection failed far short of the regulations. Especially, reservoir cleaning was managed by exterior consignment industry not low-level officials. Third, school water drinking was the most supplied through the type of water purifier. Water purifier has been distributed to city-located and middle-high school highly, factually the water from water purifier was served with water cup. Fourth, the selection standard of water drinking manager showed slightly differently by school, accordingly there need to develope integrated system with the respective to its effective systematic management. Fifth, water cup was mostly treated by only water clear, which is to vindicate the problems concerning hygiene management. 2) Utilization of school student on Drinking Water First, Disbelief on drinking water of school student was very high. Especially, proportion of middle-high school student's disbelief of drinking water was higher than elementary school student, also girls higher than boys. Many of student have heard to don't drink water from around people. And there were showed meaningful differences by area and school. Second, It was showed many student recognize had to utilize water purifier, boiled water. However, they have still drunken the tap water or portable water from their home. Third, Many of student showed negative response with the respective to the management conditions of drinking water in classroom, There were showed meaningful differences by area and school. From the fact-revealing of water cup management, Students mostly answered to 'only water clear' and the answer of 'None use' or 'With personal cup' was higher. Fourth, In bad experience of Drinking Water, student mostly answered to 'occasionally' and there were showed meaningful differences by school. student's disease experience with school drinking water was few and there were showed meaningful differences by area and gender.

As this study is the descriptive research study that tries to present the basic data aiming to establish a role of nurses for the Community Welfare Center, by surveying the role expectation and the degree of role performance towards nurses for the Community Welfare Center that nurses for the Community Welfare Center and social workers recognize, it carried out the Questionnaire research targeting nurses who are working for the Community Welfare Center located in Seoul and social workers of institutions where nurses are working, and then analyzed the results, and the study results are as follows. Both the group of nurses and the group of social workers were highly recognizing the necessity and the importance of nurses for the Community Welfare Center, and expected that more effective services will be possible to be offered by means of that nurses do work for the Community Welfare Center. However, compared to the degree that social workers recognize a nurses specialty, the nurses thought that their specialty is not acknowledged in the Community Welfare Center, and even in case of duty friction between groups being felt while social workers and nurses are working together, nurses were experiencing further friction of duties. While nurses are well recognizing their roles, they are statistically and significantly recognizing the degree of role performance lower than expected, thus the difference between the role expectation and the role performance could be seen. Also, the group of nurses showed the higher role expectation towards nurses than the group of social workers, and in relation to roles of a counselor, referral resource, an advocator, an educator, a case manager, a and a coordinator, the degree of role expectation by the group of nurses is statistically and significantly higher than the group of social workers, thus it could be seen that there is difference in the expectation degree between both groups, as to a role of nurses for the Community Welfare Center. In particular, as to a role of universally medical services, the expectations between nurses and social workers showed mutual agreement, but in relation to a role of nurses for community in the more expanded sphere, social workers did not show a receptive attitude, thus it was indicating that there exists an element of role conflict. In relation to the role performance of nurses for the Community Welfare Center, nurses were feeling the disorder degree more than social workers, in all items of disorder factors, and there was difference in recognition between nurses and social workers, as to the priority of disorder factors. Because of, through this study, having been found the difference in recognition of role expectation, the degree of role performance, and a disorder factor between nurses and social workers, as to the nurses for the Community Welfare Center, it is required a study with a more diversified method on a role of nurses for the Community Welfare Center.
