Objectives This study aimed to examine the efficacy of Korean traditional medicine treatments for recurrent lumbar disc herniation by analyzing randomized controlled trials (RCTs). Methods The following 6 databases were used Korean studies Information Service System, Oriental Medicine Advanced Searching Integrated System, Research Information Sharing Service, ScienceON, PubMed, and China National Knowledge Infrastructure. Only RCTs were selected. The risk of bias was assessed by Cochrane's risk of bias tool. Results A total of 10 RCTs were analyzed, which utilized 8 types of interventions, including acupuncture, moxibustion, warm needling, electroacupuncture, herbal medicine, cupping, and chuna manual therapy. Acupuncture and moxibustion were the most frequently used treatments. There were 7 outcome measures, including the effective rate, visual analog scale, Japanese Orthopedic Association. The effective rate was assessed in all studies. Meta-analysis results indicated that warm needling therapy and traditional Chinese medicine interventions were more effective compared with the control. Conclusions In this study, warm needling therapy and herbal medicine interventions demonstrated beneficial effects. As the meta-analysis was conducted with only a subset of RCT studies, further large-scale, systematic RCT studies are needed.

Seoul's public bicycle system, 'Ttareungyi,' introduced in 2015, has achieved an annual ridership of 40 million in 2022. Similarly, electric scooters, a type of personal mobility device, surpassed one million riders in 2020 due to various sharing platforms. However, the major roadways for these new transportation, bicycle lanes, are notably insufficient compared to other forms of transport. Hence, this study proposes an optimal location selection method for bicycle lanes in Seoul to prevent accidents and enhance bicycle ride safety. The location selection process prioritizes road safety concerning bicycle accident risk. Using regression models, high-risk areas for bicycle accidents are identified. Cluster analysis categorizes these areas into six clusters, each suggesting suitable types of bicycle lanes based on cluster-specific characteristics. We hope that this study will contribute to the improvement of Seoul's transportation environment, including the expansion of dedicated bicycle lanes and lanes for personal mobility devices.

A study was conducted to determine whether there is a difference in the incidence of kidney cancer according to income level and the difference in delayed diagnosis. To this end, the incidence of kidney cancer in Korea was analyzed by income level and by stage. From 2015 to 2017, a national kidney cancer cohort was established by linking the KCCR(Korea Central Cancer Registry), NHISS(National health insurance sharing service), and the HIRA(Health insirance review and assessment service) database to calculate the kidney cancer incidence by stage and income level. During the study period, the incidence of kidney cancer in Korea increased in all income deciles, but decreased only in the medical aid population. The incidence of kidney cancer in Korea was 7.35 per 100,000 people, and 83.54% of them were locoregional kidney cancer. In the top 20% of the income decile, there was a high incidence of 21.46 cases per 100,000 people, among which 18.37 cases were locoregional kidney cancer. On the other hand, even after adjusting for risk factors related to kidney cancer, it was confirmed that the lower the income level, the higher the risk of being diagnosed with kidney cancer with distant metastasis (lowest income 20% adj.OR 1.807, 95% CI 1.411-2.222). In the insured population, the risk ratio of being diagnosed with unknown stage was 1.926 (95% CI 1.317, 2.816). The higher the income level, the higher the frequency of early cancer diagnosis, but the lower the income level, the higher the risk of being diagnosed with metastatic kidney cancer or an unknown stage, so health inequality according to income level was observed.

It is important to grasp biometric data in real time for prompt action in the event of a safety accident at a work site where the risk of safety accidents exists. Among them, blood oxygen saturation is the most important factor in maintaining human life, so real-time oxygen saturation measurement and monitoring is necessary according to the situation as a preemptive response for worker safety management. By receiving real-time bio-signals from workers wearing health and life-risk protective clothing, and sharing and analyzing the worker's risk status in an external system, it is possible to diagnose the worker's current condition and efficiently respond to emergencies that may occur to the worker. In this paper, we propose a wearable oxygen saturation measurement platform technology that can monitor the risk of harmful gases and oxygen saturation of the wearer in real time and ensure the wearer's activity and safety in order to cope with emergency situations at the scene of an accident. If we overcome the limitations identified through the results of the proposed system later and apply improved biodata such as motion correction to the platform, we expect that it will be usable not only in hazardous gas environments, but also in hospitals and homes for emergency patients.

A lack of trust in the technical and institutional environments surrounding the web can hinder e-commerce adoption, because Internet social cues are minimal and trust is difficult th establish. Web vendors must act purposefully to overcome consumer perceptions of uncertainty and risk by building trust-both in their own web sites and in the broader Internet environments. Trust makes consumers comfortable by sharing personal information making purchases, and acting on web vendor advice-behaviors essential to wide-spread adoption of e-commerce. Understanding the nature and antecedents of trust is, therefore, a major issue for both Internet researchers and practitioners. Prior research on e-commerce trust has used diverse, incomplete, and inconsistent definitions of trust therefore, making it difficult to compare results across studies. This study tried to and the empirical relationships among the trust-related factors on the usage of Internet shooing mall. The model includes five high-level constructs-disposition to trust institution-based trust trusting beliefs, trusting intention and environmental factors. The results showed that the disposition to trust and the environmental factors had a significant effect on the web site trust however, their effect was not consistent Moreover, the model suggested in this study need to be extended including with the more sociological factors and results in this study required to be verified with those extended model.

This paper analyzes a situation where multiple targets are exposed to a potential terrorist attack. The probability of an attack is determined endogenously in a game where a terrorist chooses the target while the targets independently determine the level of deterrence. As each target tries to divert an attack to others, the symmetric equilibrium becomes suboptimal and exhibits dispersion in the level of deterrence. The analysis shows that the first best deterrence level may be achieved when the targets can write a binding risk-sharing contract. Such a contract has limited applicability however as it suffers from a potential verification problem.

Smartphones change the picture of data and information sharing and make it possible to share various real-time flooding data and information. The vulnerability indicators of farmland inundation is needed to calculate the risk of farmland flood based on changeable hydro-meteorological data over time with morphologic characteristics of flood-damaged areas. To find related variables show the vulnerability of farmland inundation using the binary-logit model and correlation analysis and to provide vulnerability indicators were estimated by fuzzy set method. The outputs of vulnerability indicators were compared with the results of Monte Carlo simulation (MCS) for verification. From the result vulnerability indicators are applicable to mobile_based information system of farmland inundation.

This paper has tried to research the perception of pilots in a commercial airliners or full service carriers focusing on the airliner's safety management system (SMS). ICAO requires the airliners to set up the basic standards of SMS since the SMS is believed to be the core of the aviation risk management. According to the previous study, it was proved safety climate of an airline affects the safety behavior of cockpit crews. Safety climate is different from safety culture and the safety climate has an advantage to be measured more quantitatively than the culture. That is, the safety climate could be represented as SMS. As the results of the empirical study based on Chen & Chen(2014)'s SMS practice sacle, it had been assumed at the beginning the major factors such as Clarification of SMS, Safety Training for Crews and Sharing of SMS Information have positive effects on the motivation for safety behaviors. The motivation is directly correlated to crews' safety behaviors. However, the result showed the clarification of SMS has not a significant effect on their safety behaviors. The main reason is cockpit crews, through the survey, perceived airline seemed to have no definite standards of SMS and the senior management to have less interest in aviation safety.

In this paper, we redesign, implement, and evaluate ShareSafe (Based on SecGraph), an open-source secure graph data sharing/publishing platform. Within ShareSafe, we propose De-anonymization Quantification Module and Recommendation Module. Besides, we model the attackers' background knowledge and evaluate the relation between graph data privacy and the structure of the graph. To the best of our knowledge, ShareSafe is the first platform that enables users to perform data perturbation, utility evaluation, De-A evaluation, and Privacy Quantification. Leveraging ShareSafe, we conduct a more comprehensive and advanced utility and privacy evaluation. The results demonstrate that (1) The risk of privacy leakage of anonymized graph increases with the attackers' background knowledge. (2) For a successful de-anonymization attack, the seed mapping, even relatively small, plays a much more important role than the auxiliary graph. (3) The structure of graph has a fundamental and significant effect on the utility and privacy of the graph. (4) There is no optimal anonymization/de-anonymization algorithm. For different environment, the performance of each algorithm varies from each other.

Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.
