Exposure to ultraviolet (UV) light is often associated with skin damage, sometimes very serious, and in recent times has received particular attention as a health risk. As a result, the proper use of sunscreen has long been recommended to protect against skin damage. The continued increase in the use of sunscreen may be linked to increased information about the risk of melanoma and non-melanoma skin cancer caused by prolonged exposure to ultraviolet rays. Natural and harmless materials that block and prevent UV light have emerged as essential household items in the field of skin beauty. New materials need to be considered and evaluated in relation to ultraviolet rays and their harmful effects. This study aims to explain the effect of UV exposure on human skin, the classification of sunscreens, the application of zeolite, nano clay, and LDH in sunscreen formulations, as well as the regulation of this service in various countries around the world.

Water contamination in a water distribution network (WDN) is harmful since it directly induces the consumer's health problem and suspends water service in a wide area. Actions need to be taken rapidly to countermeasure a contamination event. A contaminant source ident ification (CSI) is an important initial step to mitigate the harmful event. Here, a CSI approach focused on determining the contaminant intrusion possible location and time (PLoT) is introduced. One of the methods to discover the PLoT is an inverse calculation to connect all the paths leading to the report specification of a sensor. A filtering procedure is then applied to narrow down the PLoT using the results from individual sensors. First, we spatially reduce the suspect intrusion points by locating the highly suspicious nodes that have similar intrusion time. Then, we narrow the possible intrusion time by matching the suspicious intrusion time to the reported information. Finally, a likelihood-score is estimated for each suspect. Another important aspect that needs to be considered in CSI is that there are inherent uncertainties, such as the variations in user demand and inaccuracy of sensor data. The uncertainties can lead to overlooking the real intrusion point and time. To reflect the uncertainties in the CSI process, the Monte-Carlo Simulation (MCS) is conducted to explore the ranges of PLoT. By analyzing all the accumulated scores through the random sets, a spread of contaminant intrusion PLoT can then be identified in the network.

Purpose: This study investigated how interprofessional education (IPE) related to medication for undergraduate healthcare students, including nursing students, has been designed and conducted. Furthermore, the outcomes of these IPE programs were evaluated. Methods: A scoping review was performed to understand the content and methods of IPE on medication for undergraduate healthcare students, including nursing students. A literature search was done using PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Research Information Sharing Service, and Korean Nursing Database in English between January 2000 and December 2022. In total, 14 papers were selected and reviewed. Results: Eleven research studies were conducted on the implementation of one-time IPE on medication safety or errors. Among them, six studies focused on providing IPE to nursing students alongside medical and pharmacy students, while three studies targeted nursing and medical students, and two studies focused on nursing and pharmacy students. The most commonly employed educational method was simulation, which was utilized in 12 studies. All studies consistently reported a positive impact on attitudes toward IPE and effective communication. Additionally, five studies evaluating medication knowledge reported improvements in participants' understanding of drugs. Conclusion: The effects of IPE related to medication for undergraduate nursing students have been confirmed. It is necessary to introduce IPE in the field of pharmacology.

Objective: This study aimed to retrospectively analyze the prevalence of orthodontic problems and the proportion of patients who underwent orthodontic diagnosis among children aged 6 (n = 300), 7 (n = 400), and 8 (n = 400) years who had undergone panoramic radiography. Methods: Children were divided into five groups according to their chief complaint and consultation: conservative dentistry, oral and maxillofacial surgery, orthodontics, periodontics, and prosthodontics). Chief complaints investigated included first molar eruption, lack of space for incisor eruption, frequency of eruption problems, lack of space, impaction, supernumerary teeth (SNT), missing teeth, and ectropion eruption. The number of patients whose chief complaint was not related to orthodontics but had dental problems requiring orthodontic treatment was counted. The proportion of patients with orthodontic problems who received an orthodontic diagnosis was also examined. Results: Dental trauma and SNT were the most frequent chief complaints among the children. The proportion of patients with orthodontic problems increased with age. However, the orthodontic diagnosis rates based on panoramic radiographs among children aged 6, 7, 8 years were only 1.5% (6 years) and 23% (7 and 8 years). Conclusions: Accurate information should be provided to patient caregivers to correct misconceptions regarding the appropriateness of delaying orthodontic examination until permanent dentition is established.

Objectives This study aimed to assess the effects of oral administration of deer antler extracts on an osteoporosis-induced animal model. We analyzed the results of using deer antler single extracts on animal models with osteoporosis through a systematic review and meta-analysis. Methods We included osteoporosis studies in animal experiments that administrated deer antler extracts orally. We searched the following 13 databases without a language restriction: PubMed, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), China National Knowledge Infrastructure (CNKI), Wanfang, Korean Medical Database (KMbase), National Digital Science Library (NDSL), Korean Traditional Knowledge (Koreantk), Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), Korea Institute of Science and Technology Information (KISTI), and Koreanstudies Information Service System (KISS). We used Systematic Review Centre for Laboratory Animal Experimentation's risk of bias tool for assessing the methodological quality of the included studies. Results A total of 299 potentially relevant studies were searched and 11 were included for a systematic review. Nine studies used a single deer antler extract. A study compared the effects of single extracts of deer antler and antler glue, while another study compared the effects of three single extracts of deer antler, old antler, and antler glue. For evaluating the intervention effect, bone mineral density (BMD) was measured as the primary outcome, while the histomorphometric indicators of the bone and serum alkaline phosphatase and osteocalcin levels were used as the secondary outcome variables. On conducting a meta-analysis of studies on single deer antler extract, BMD was observed to be significantly increased compared to that in control group (standardized mean difference [SMD]=2.11; 95% confidence interval [CI]=1.58~2.65; Z=7.75; p<0.00001; I²=56%). As a result of meta-analysis, according to the concentration of deer antler, the group with high concentration showed statistically significantly higher BMD than the group with low concentration (SMD=1.28; 95% CI=0.74~1.82; Z=4.63; p<0.00001; I²=9%). Conclusions The research shows that the deer antler extracts have significant anti-osteoporotic effects on the osteoporosis-induced animal model. However the studies included in this research had a high methodological risk of bias. This indicates the requirement of considerable attention in the interpretation of the study results.

Objectives: We aimed to evaluate the use of Korean medicine in patients with dizziness or vertigo, since such study has not been performed previously. Methods: In the current study, we included 3 diagnoses i.e., Disorders of vestibular function (H81), Vertiginous syndromes in diseases classified elsewhere (H82), and Dizziness and giddiness (R42) from the Health Insurance Review and Assessment Service (HIRAS) database for 4 years. We analyzed the database and compared treatment with Korean vs. Western medicine. Results: 1. Korean medical visits and cost have been increasing for 4 years, except 2011. Western medical visits are 11.9 times higher than Korean medical visits. 2. The number of women who received Korean medicine was 2.6 times higher than that of men. 3. Among all ages, the 70~79 years group were the most frequent users of Korean medicine. The older age was correlated with more patients' visits. 4. The comparative number of visits by patient care type for 4 years indicated that outpatients had more visits than hospitalization. Furthermore, outpatient visits have been increasing for 4 years. 5. The comparative number of visits by hospital type for 4 years indicated that visits to the Korean medical clinic were the highest. In primary care, patients used more Korean medicine than Western medicine. In tertiary care, patients used more Western medicine than Korean medicine. 6. Korean medical cost per patient by patient care type for 4 years was a total 89,000 won, hospitalization 449,000 won and outpatient 83,000 won. Costs of all patient care types have been increasing. 7. Korean medical cost per patient by hospital type for 4 years was 156,000 won for Korean medical hospital, 83,000 won for local clinic and 127,000 won for miscellaneous facilities. Costs of all types have been increasing. Conclusions: This study provided objective information about epidemiologic characteristics of Korean medicine in patients with dizziness or vertigo.

A two-step open system(TOS) was proposed to relay between a healing platform and a repository of personal health documents. TOS was designed by taking into consideration the pubsub service based on large scale connections to monitor a provider's access/request process for health documents in real time. TOS, however, uses WebSocket as a communication protocol in case of pubsub. Given the operational environment of low quality wireless networks for mobile devices that are user terminals in a healing platform, there is a need to add a messaging protocol to support QoS as well as a transmission protocol. As a light messaging protocol optimized for mobile devices, MQTT defines reliable messaging QoS to consider a wireless network situation of low speed/low quality. This study designed an MQTT protocol-based message broker to support QoS in case of large scale connections and pubsub by taking into consideration mobile devices that are user terminals in a healing platform. After designing a model between TOS and MQTT message broker, the study implemented a prototype based on the proposed design and compared it with its counterparts from previous studies based on the performance indicators in a load-test with the MQTT client tool.
