During New year's day and Thanksgiving holiday, the 1339 Information Center in Gwangju and Jeonnam received an emergency medical situation and carried out the analysis as follows ; 1. The reason for the higher phone guidance(72%) of the hospital was based on the simple query for the pain control rather than emergency care. This was explained by the unfamiliar environment of the holiday movers. Pharmaceutical guidance(12.6%) in rural area was also given during the holidays. 2. The disease counselling(2.4%) and emergency treatment instruction(First Aid)(1.6%) decreased because of the small number of request for the diseases. This explained the decrease of the disease counselling. 3. The phone calls increased 8-13 times more than usual. Five-day holidays could have more emergency patients than three-day holidays. During New year's day and Thanksgiving day, the number of received phone calls was 6,444(25.7%) and this accounted for one fourth of the total number in 2007. 4. The number of the patients increased on New year's day and Thanksgiving day because most of the medical institutions and pharmacy were off duty. 5. The patients were centered in Internal medicine and pediatrics. This showed the food-borne diseases and air-borne infection such as common cold. 6. During Thanksgiving day, ophthalmologic patients having viral keratoconjunctivitis(Apollo eye disease) increased 8 folds than in New year's day. It was estimated from the continuous epidemic of Apollo eye disease. 7. There broke out the traffic accidents, food poisoning, infectious diseases, dermatological diseases due to seasonal and environmental changes during the holiday move.

Purpose: At the beginning of the Coronavirus disease (COVID-19) epidemic, physicians paid close attention to children with chronic diseases to prevent transmission or a severe course of infection. We aimed to measure the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody levels in children with chronic gastrointestinal and liver diseases to analyze the risk factors for infection and its interaction with their primary disease. Methods: This cross-sectional study analyzed SARS-CoV-2 antibody levels in patients with gastrointestinal and liver diseases (n=141) and in healthy children (n=48) between January and February 2021. Results: During the pandemic, 10 patients (7%) and 1 child (2%) had confirmed COVID-19 infection (p=0.2). The SARS-CoV-2 antibody test was positive in 36 patients (25.5%) and 11 children (22.9%) (p=0.7). SARS-CoV-2 antibody positivity was found in 20.4%, 26.6%, 33.3%, and 33.3% of patients with chronic liver diseases, chronic gastrointestinal tract diseases, cystic fibrosis, and liver transplantation recipients, respectively (p>0.05, patients vs. healthy children). Risk factors for SARS-CoV-2 antibody positivity were COVID-19-related symptoms (47.2% vs. 14.2%, p=0.00004) and close contact with SARS-CoV-2 polymerase chain reaction-positive patients (69.4% vs. 9%, p<0.00001). The use, number, and type of immunosuppressants and primary diagnosis were not associated with SARS-CoV-2 antibody positivity. The frequency of disease activation/flare was not significant in patients with (8.3%) or without (14.2%) antibody positivity (p=0.35). Conclusion: SARS-CoV-2 antibodies in children with chronic gastrointestinal and liver diseases are similar to that in healthy children. Close follow-up is important to understand the long-term effects of past COVID-19 infection in these children.

Obesity is psychological and socioeconomic problems as well as health problems related to physical disease and disorder. The obesity epidemic, including a marked increase in the prevalence of obesity among pregnant women, represents a critical public health problem throughout the world. Gung-Gui-Tang (GGT), a prescription of traditional Korean medicine, has been used to treat dizziness due to loss of blood as well as static blood after childbirth. However, the therapeutic potential of GGT on postpartum obesity has not been fully elucidated in an experimental model. In our research, GGT inhibited the increases of body weight and adipose tissues in postpartum mice fed a high-fat diet. GGT also inhibited the elevations of plasma lipid profiles such as triglyceride, low-density lipoprotein cholesterol, total cholesterol, and glutamate pyruvate transaminase. Overall, these results provide evidence that GGT can help to inhibit postpartum obesity and open new perspective to recover the shape of mother into the moment of conception.

In this paper we consider a model with demographics for sexually transmitted diseases (STDs) spread on scale-free networks. We derive the epidemic threshold, which is depend on the birth rate, the natural death rate and other parameters. The absence of a threshold in infinite scale-free network is proved. For a hard cut off scale-free network, we also analyze the stability of disease-free equilibrium and the persistence of STDs infection. Two immunization schemes, proportional scheme and targeted vaccination, are studied and compared. We find that targeted strategy is more effective on scale-free networks.

In this paper, we aim to construct a nonstandard finite difference (NSFD) scheme to solve numerically a mathematical model for cholera epidemic dynamics. We first show that if the basic reproduction number is less than unity, the disease-free equilibrium (DFE) is locally asymptotically stable. Moreover, we mainly establish the global stability analysis of the DFE and endemic equilibrium by using suitable Lyapunov functionals regardless of the time step size. Finally, numerical simulations with different time step sizes and initial conditions are carried out and comparisons are made with other well-known methods to illustrate the main theoretical results.

Jangseoksun(張錫純), a noted doctor of China in the early 20th century, has influenced the establishment of Contemporary Chinese Medicine greatly. , which is an accumulation of Jang's lectures and publications, contains the essence of his medical spirit to fuse his theory and experience of Traditional Medicine and the newly imported Western Medicine knowledge of his time. is especially important, presenting the core of Jang's academic theory. In this book he gives full play of his unique experience of treating the Eum(陰, Yin) Deficiency Syndrome which is presented as excess in the upper and deficiency in the lower[上盛下虛]. He also shows the importance of merging theory and practice, the pliability to collaborate the Sanghan(傷寒, Damage from Cold) theory and Onbyeong(溫病, Epidemic Febrile Disease) theory and the study of the blended affect of external and internal pathogens.

With dramatic transitions from a traditionally food-insecure to a food-sufficient society, over weight and/or obesity are an increasing health concern in Korea. In 2000, $35.9\%$ of Korean adults were over weight (BMI>25) with increasing trends. It is well known that obesity is highly correlated with chronic diseases, such as diabetes, hypertension, cardiovascular disease, cancer and high cholesterol. In 2003, the social cost of obesity is estimated at $529.5\~799.3$ billion won (direct cost) and at $1,200\~1,817$ billion won (including indirect cost). The share of the direct cost is estimated at $2.6\~3.9\%$ of total medical bill 20,742 billion won. These costs are underestimated and would surely be higher if the expenditures outside of the official medical insurance system of Korea were included. Based on the rapid increase of obesity rate among the Korean youth, it is crucial to develop and implement appropriate policies to curb the obesity epidemic.

Physical inactivity has reached epidemic levels in developed countries and is being recognized as a serious public health problem. Recent evidence shows a high percentages of individuals worldwide who are physically inactive, i.e. do not achieve the WHO's present recommendation of 150 minutes of moderate to vigorous intensity per week in addition to usual activities. Living in sedentary lifestyle is one of the leading causes of deaths and a high risk factor for several chronic diseases, like cancer, cardiovascular disease, diabetes type 2, and osteoporosis. This article summarizes evidence for relative risk of the civilization diseases attributable to physical inactivity and the most important conclusions available from the recent investigations computing the economic costs specific to physical inactivity. The findings provide health and economic arguments needed for people to understand the meaning of a sedentary lifestyle. This may be also useful for public health policy in the creation of programmes for prevention of physical inactivity.

Porcine epidemic diarrhea (PED), transmissible gastroenteritis (TGE) are an acute viral enteritis. colibacillosis by E coli is a microbial enteritic disease in suckling piglets[1]. These infectious intestinal diarrheal diseases cause severe diarrhea to suckling piglets, so that lead to enormous economical loss in swine-product industries. Ig-Top (AD Biotech, Korea) is a immunomodulator with IgY the specific yolk-antibody for PED, TGE and E. coli and oligosaccharide. The purpose of this study was to investigate protective effects against PED virus, TGE virus E.coli and in suckling piglets by oral administration of the Ig-Top. (omitted)
