Moraceae comprise a large family of sixty genera and neary 1,400 specieses, including important groups such as Artocarpus, Morus, and Ficus. In particular, Morus(mulberry) is a small genus of tree and shrubs found in temperate and subtropical regions of the Northern hemishere and has been widely cultivated in China and Korea, In addition, the root bark of mulberry tree have been used as an antiphlogic, diuretic, and expectorant in white medicine, and the crude drug is known as "Sangbaikpi" in Korea. Recently, some papers have been published reporting the hypotensive effect, antiviral effect, antifungal effect, inhibitory effect of cAMP-phosphodiesterase, and anticancer effect of this extract. Little is known about that Cortex mori could have been an antiallergic effect. The purpose of this study was the development of an antiallergic agent with an antiallergic effect from Cortex mori. For this, several in vivo and in vitro experimental models were used. Results are 1) Cortex mori inhibited the compound 48/80-induced degranu-lation, histamine release and calcium uptake of rat peritoneal mast cells, 2) compound 48/80-induced anaphylactic shock and cutaneous reaction were significantly inhibited by pretreatment of Cortex mori, and 3) Cortex mori inhibited the ovalbumin-induced late astmatic reaction. From the above results it is suggested that Cortex mori has some substances with an antiallergic activity. Our final purpose of this study is to develope the new drug with an antiallergic activity from Cortex mori

Water-assisted synthesis of carbon nanotubes (CNTs) has been intensively studied in recent years, reporting that water vapor enhances the activity and lifetime of metal catalyst for the CNT growth. While most of these studies has been focused on the supergrowth of CNTs at high temperature, rarely has the similar approach been made for the CNT synthesis at low temperature. Since the metal catalyst are much less active at lower temperature, we expect that the addition of water vapor may increase the activity of catalyst more largely at lower temperature. We synthesized multi-walled CNTs at temperature as low as $360^{\circ}C$ by introducing water vapor during growth. The water addition caused CNTs to grow ~3 times faster. Moreover, the water-assisted growth prolonged the termination of CNT growth, implying the enhancement of catalyst lifetime. In general, a thinner catalyst layer is likely to produce smaller-diameter, longer CNTs. In a similar manner, the water vapor had a greater effect on the growth of CNTs for a smaller thickness of catalyst in this study. To figure out the role of process gases, CNTs were grown in the first stage and then exposed to each of process gases in the second stage. It was shown that water vapor and hydrogen did not etch CNTs while acetylene led to the additional growth of CNTs even faster in the second stage. As-grown CNTs were characterized by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and Raman spectroscopy.

Background: Mahuang (Ephedra sinica STAPF) is well known as an herbal medicine and has been widely used to reduce body weight and increase athletic ability. However, as a result of reporting many cases of adverse effects on the cardiovascular system, use of dietary supplements containing ephedra was prohibited by the FDA. Objectives : The object of this study was to find the effectiveness of ephedra on weight loss without severe adverse effect. Methods : 16 healthy volunteers consisting of an ephedra group (N=8) and a placebo group (N=8) were investigated. Study form was a randomized, controlled, double-blind clinical trial. The ephedra group took 12g of ephedra while the placebo group took 12g of glutinous rice powder. Both groups were measured with BCA (body composition analysis) on weight loss and with HRV (heart rate variability) on its adverse effect before and after medication. Results : The following results were obtained after taking 12g of ephedra for 14 days. In the ephedra group, body weight reduced significantly. In the placebo group, there were no significant differences of body weight between before and after placebo treatment. There was a slight increase of heart beat rate and deactivation of cardiac activity. Parasympathetic nerves were deactivated, but balances of autonomic nervous system were well maintained. Conclusions : The results suggest that ephedra in healthy adults tends to reduce body weight and deactivation of autonomic nervous system and cardiac activity.

Objectives: The purpose of this study was to examine the relationship of meeting the recommended levels of physical activity (PA) with health status and preventive health behavior in adults. Methods: A total of 5630 adults 18 years of age or older were included in this study. PA was assessed using a series of questions that categorized activities based on their metabolic equivalent values and then categorized individuals based on the reported frequency and duration of such activities. Participants reporting 150 minutes or more of moderate-intensity PA per week were considered to have met the PA guidelines. Multiple logistic regression was used to model the relationships between meeting PA guidelines and health status and preventive health behavior, while controlling for confounding variables. Results: Overall, 53.9% (95% confidence interval [CI], 51.9 to 55.9%) of adults reported meeting the recommended levels of PA. Among adults with good general health, 56.9% (95% CI, 54.7 to 59.1%) reported meeting the recommended levels of PA versus 43.1% (95% CI, 40.9 to 45.3%) who did not. Adults who met the PA guidelines were significantly more likely not to report high cholesterol, diabetes, chronic obstructive pulmonary disease, arthritis, asthma, depression, or overweight. Furthermore, adults meeting the PA guidelines were significantly more likely to report having health insurance, consuming fruits daily, consuming vegetables daily, and not being a current cigarette smoker. Conclusions: In this study, we found meeting the current guidelines for PA to have a protective relationship with both health status and health behavior in adults. Health promotion programs should focus on strategies that help individuals meet the current guidelines of at least 150 minutes per week of moderate-intensity PA.

As people's interest about wildlife animal increases, more wildlife animal centers are developing. In South Korea, currently 120 mammal species live, and 22 of them are designated as endangered species. It is important to protect these natural treasures and endangered species, because they are being harmed by human industrial activity. For example, road expansion and poaching have led to the destruction of wildlife animal habitats, which is increasing year by year. Nevertheless, data regarding the systematic treatment of wild animals that are in distress is lacking, and it is a reality that analysis of such data is also lacking. The Kangwon Wildlife Rescue Center investigates these types of distress experienced by mammals. By analyzing the shape of the wild animals killed or injured, the center seeks an efficient and systematic way to manage such distress. The data collected from the Wildlife Animal Center from September 2007 to August 2010 includes 195 different cases, and the animals point of rescue. There are 16 species, including 87 water deer (Hydropotes inermis), 39 raccoons (Nyctereutes procyonoides), 20 roe deer (Capreolus pygargus bedfordi), 10 goral (Nemorhaedus goral), 7 siberian weasels (Mustela sibirica), 6 otters (Lutra lutra) and etc. Within the first year (September 2007 to August 2008), the number of mammals rescued was 46. In the second year (September 2008 to August 2009), 60 animals were rescued. in the third year (September 2009 to August 2010), the Wildlife Animal Center had 89 animals. We can see that these numbers are increasing, which shows that people are interested in the well-being of these animals because they are reporting animal injuries more and more. The mains form of distress caused by humans are from car accidents 67 (34.4%). Traps, and other hunting tools used by poachers are responsible for 25 (13.0%). Also, human industrial activity thus indirectly led to the starvation 25 (13.0%). and the orphaning of young animals 37 (19.0%).

This study shares details on the operating process and results of the cohort of students and graduates that was designed and implemented at Konyang University College of Medicine in Daejeon and discusses future directions for cohort establishment and improvement. First, Konyang University College of Medicine established the necessity and defined the purpose of cohort design and implementation. A task force was formed to establish guidelines for analysis targets, procedures, reports, and data management, and cohort operation was classified as a quality control activity. Data were collected through surveys of current students and graduates, and data generated during the curriculum were collected, analyzed, and reported every 2 years. The cohort data collection and analysis methods are designed by the Department of Medical Education, and data collection is carried out by the administrative team and each committee. Data management and analysis are handled by the Center for Medical Education Support, and analysis and reporting are conducted by the Department of Medical Education. Various members of the medical school are working to collect and analyze data, report findings, provide feedback, and improve. In the future, we plan to advance database computerization and work toward more effective data analysis. Cohort operation should not be another burden for medical schools; instead, it is hoped that operating cohorts will be a meaningful activity to increase the effectiveness of medical education and help in the operation and policy decisions of medical schools.

Purpose: This study aimed to evaluate the effectiveness of exercise in patients with hemophilia. Methods: We carried out a systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. A literature search was conducted of published randomized controlled trials for exercise interventions from January 1, 2014 to March 15, 2023. To estimate the size of the effects of exercise, a meta-analysis was performed using the R package "meta." Results: Five databases were searched to obtain articles published in Korean or English. Of 1,150 articles reviewed, 13 were included in the systematic review and 9 in the meta-analysis. The risk of bias was assessed using RoB 2.0. The overall effect sizes of exercise interventions, calculated as the standardized mean difference, were -0.11 (95% confidence interval [CI] = -1.41 to -1.20) for pain, -2.13 (95% CI = -3.33 to -0.93) for joint health, 9.96 (95% CI = 7.51 to 12.28) for physical activity, and 0.59 (95% CI = -0.39 to -1.56) for quality of life. Conclusion: These findings suggest that exercise is useful for improving the joint health and physical activity of patients with hemophilia. Thus, it is necessary to develop and apply exercise interventions for patients with hemophilia to reduce their pain and improve their quality of life.
