Objectives: This study aimed to evaluate the efficacy and safety of Bojungikgi-tang (BJIG) and its modifications for patients with anemia. Methods: The subject of analysis of this study was a parallel design randomized controlled trial in which BJIG or its modifications was administered orally to patients who met the World Health Organization's anemia criteria and the efficacy and safety were prospectively measured. Electronic databases were searched to retrieve eligible literature published from 1 January 2000 to 12 February 2023. A meta-analysis was conducted, and the risk of bias (RoB) and level of evidence of the included studies was assessed using the Cochrane RoB 2 tool and GRADE method, respectively. Results: Five studies were included in the meta-analysis. When BJIG or its modifications was administered to anemia patients receiving conventional treatment, additional benefits compared to the non-administered group were found in terms of an increase in red blood cell count (mean difference (MD) 0.46 × 10¹²/L, 95% confidence interval (CI) 0.17 to 0.74), hemoglobin concentration (MD 9.28 g/L, 95% CI 6.06 to 12.51), hematocrit (MD 2.57%, 95% CI 1.76 to 3.38), total effective rate (odds ratio 5.29, 95% CI 2.05 to 13.68), and traditional Chinese medicine symptom scores (standardized MD -1.51, 95% CI -2.79 to -0.24). Conclusions: This study demonstrated the clinical potential of BJIG and its modifications to provide additional benefits to patients with anemia receiving conventional treatment.

Safety at sea continues to be an important topic for research. The factors that contribute to safety issues are often complex and unclear. Lack of non-technical skills in such areas as communication, teamworking, situational awareness, decision making etc. are well documented as directly affecting safety in high risk work settings such as on board merchant vessels. Competence in non-technical skills can be affected by various habits and circumstances that influence a worker and result in either positive thinking and behaviour or negative thinking and behaviour. Negative thinking can cause stress, anger, frustration; loneliness etc. and this can possibly result in behaviour or actions that undermine the safety of crew and ship. Factors that may contribute to these negative thoughts and behaviours are many and varied and this paper will be looking at one aspect: mobile phone use. In the Republic of Korea, dependency on mobile phones is uniquely high. Maritime students are also susceptible to such dependency and this paper will demonstrate that the symptoms associated with mobile phone addiction and dependency, and in particular the symptoms of withdrawal, are important factors that need to be mitigated in order to improve safety at sea. Although the benefits of mobile phones are many it will be suggested that over-reliance, dependency or addiction can result in negative thinking or behaviour that may directly or indirectly contribute to the factors that cause incidents and accidents at sea. It will be suggested that the most appropriate method of dealing with this problem is twofold: firstly, through training at the educational level and secondly, by encouraging the shipping industry and government to invest more into providing seafarers with better access to the communication methods that they are used to on shore in order to improve work conditions.

The use of chemicals to enhance and improve life is a widespread practice worldwide. But alongside the benefits of these products, there is also the potential for adverse effects to people or the environment. Thus, If anyone handles hazardous chemicals, they should adhere to specific criteria for hazardous chemicals. This study used hazard statement(H-code) and precautionary statement(P-code) to set specific criteria for handling chemicals. According to the UN GHS, hazard statement means a statement assigned to a hazard class and category that describes. And a precautionary statement is a phrase which describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposures to a hazardous product, or improper storage or handling of a hazardous product. The study suggests the treatment criteria(Public Notice) of 785 types of hazardous chemicals managed by the Chemical Control Act.

Growth promoters have been widely used as a strategy to improve productivity, and great benefits have been observed throughout the meat production chain. However, the prohibition of growth promoters in several countries, as well as consumer rejection, has led industry and the academy to search for alternatives. For decades, the inclusion of phytochemicals in animal feed has been proposed as a replacement for traditional growth promoters. However, there are many concerns about the application of phytochemicals and their impact on the various links in the meat production chain (productive performance, carcass and meat quality). Therefore, the effects of these feed additives are reviewed in this article, along with their potential safety and consumer benefits, to understand the current state of their use. In summary, the replacement of traditional growth promoters in experiments with broilers yielded benefits in all aspects of the meat production chain, such as improvements in productive performance and carcass and meat quality. Although the effects in pigs have been similar to those observed in broilers, fewer studies have been carried out in pigs, and there is a need to define the types of phytochemicals to be used and the appropriate stages for adding such compounds. In regard to ruminant diets, few studies have been conducted, and their results have been inconclusive. Therefore, it is necessary to propose more in vivo studies to determine other strategies for phytochemical inclusion in the production phases and to select the appropriate types of compounds. It is also necessary to define the variables that will best elucidate the mechanism(s) of action that will enable the future replacement of synthetic growth promoters with phytochemical feed additives.

The effects of weather on aircraft operations are predominant. In particular, severe weather, such as fog, strong winds, rainfall and snow, can cause delays, diversion or cancellation of operations. Of these, fog is considered the main reason for restricting aircraft operations. Meanwhile, Precision instrument approach using instrument landing system(ILS) has allowed aircraft to land safely even in situations where visibility is limited. However, the precision instrument approach require not only the performance of the aircraft but also the enhancement of the runway. In November 2018, Gimpo international Airport raised the category of the runway 14R from CAT-IIIa to CAT-IIIb to improve aviation safety and operational efficiency. Based on this, the research presented a methodology for estimating benefits according to the category upgrade of the precision approach runway, and estimated the benefits to Gimpo International Airport based on the methodology presented.

Although Mycoplasma pneumoniae pneumonia (MPP) has been generally susceptible to macrolides, the emergence of macrolide-resistant MPP (MRMP) has made its treatment challenging. MRMP rapidly spread after the 2000s, especially in East Asia. MRMP is more common in children and adolescents than in adults, which is likely related to the frequent use of macrolides for treating M. pneumoniae infections in children. MRMP is unlikely to be related to clinical, laboratory, or radiological severity, although it likely prolongs the persistence of symptoms and the length of hospital stay. Thereby, it causes an increased burden of the disease and poor quality of life for the patient as well as a societal socioeconomic burden. To date, the only alternative treatments for MRMP are secondary antimicrobials such as tetracyclines (TCs) or fluoroquinolones (FQs) or systemic corticosteroids; however, the former are contraindicated in children because of concerns about potential adverse events (i.e., tooth discoloration or tendinopathy). A few guidelines recommended TCs or FQs as the second-line drug of choice for treating MRMP. However, there have been no evidence-based guidelines. Furthermore, safety issues have not yet been resolved. Therefore, this article aimed to review the benefits and risks of therapeutic alternatives for treating MRMP in children and review the recommendations of international or regional guidelines and specific considerations for their practical application.

While the use of radiation in the medical field provides diagnosis and treatment with important benefits, we cannot deny that the radiation bombing causes some hindrances. The expansion of radiation use in modem medicine is essential, so the radiation use and preparation of proper measure for safety management has risen as a pressing subject. Therefore, in order to make defensive plans for the prevention of health obstacles to general users of radiation and for the provision of basic data of the health education programs to radiation workers by grasping the knowledge, attitude and behavior towards the radiation safety management of radiation workers in each medical institution and by analyzing the factors that affect the actions of radiation safety management, in this study we conducted questionnaires from September 26 to November 5, 2001 targeting 805 radiation workers in 108 medical institutions including university hospitals, general hospitals, hospitals, clinics and public health centers etc. located in Seoul, four metropolitan cities and small and medium cities, and has obtained the following results. 1. The average point of knowledge on the radiation safety management was 10.96 out of 15. As for the general characteristics, the level of knowledge on radiation safety management was higher with older age, high education background and longer career. 2. The average point of attitude on the radiation safety management was 66.36 out of 75. The attitude point for general characteristics were higher with higher education background, longer career and in case of universities, the level of attitude on the radiation safety management was high. 3. The average of action points on the radiation safety management was 56.09 out of 75. In general characteristics, the action level of radiation safety level was higher with older age, longer career, and the reception of radiation education and in case of university hospitals. 4. It is analyzed that the relation of knowledge, attitude and behavior on the radiation safety management is higher as the levels of knowledge and attitude on the radiation safety management is higher. 5. As a result of analyzing the factors that affect the knowledge on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘work career’, ‘the attitude on the radiation safety management’, and ‘school career’. 6. As a result of analyzing the factors that affect the attitude on the radiation safety management, the variables that can be explained best was in the order of ‘the behavior on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘school career’. 7. As a result of analyzing the factors that affect the behavior on the radiation safety management, the variables that can be explained best was in the order of ‘the attitude on the radiation safety management’, ‘the knowledge on the radiation safety management’, and ‘the frequency of radiation education
