Tuberculosis is a disease with high morbidity and mortality in children worldwide. Despite significant improvements in diagnostic methods, scientific researches and clinical trials for new regimens of treatment or prevention in adult tuberculosis, childhood tuberculosis has been relatively neglected. Children are at high risk of severe disease, and reactivation of latent infection in adulthood perpetuates the epidemic. Therefore, a policy of tuberculosis control in childhood should be emphasized to improve control in the total population. To understand the new view of childhood tuberculosis, this article describes changes in the disease's national epidemiology, new diagnostic tools and treatment strategies, and multi-drug resistance.

A brown leaf and stem spot disease of bayonet-grass (Scirpus maritimus) was epidemic in reclaimed paddy fields of Chunbuk province, Korea. A fungal pathogen was repeatedly isolated from the necrotic lesions of the bayonet-grass and identified as Nimbya scirpicola. The pathogen induced disease symptoms only in bayonet-grass but not in 8 other plants tested; Brassica pathogen induced disease symptoms only in bayonet-grass but not in 8 other plants tested; Brassica compestris subsp. napus var. pekinensis, Cucumis sativus, Glycine max, Hordeum vulgare, Lycopersicon esculentum, Oryza sativa, Sesamum indicum and Triticum aestivum. The fungus has potential to be developed as a mycoherbicide.

Bacterial canker of kiwifruit recently outbroke throughout the southcoast of Korea, the major production areas of kiwifruit. Some orchards were destroyed because of severe damage by the epidemics of the bacterial canker, especially in Jeju-si and Bukjeju-kun, Jeju and Goheung-kun and Wando-kun, Chonnam. The bacterial canker, which has been occurred in Jeju from the mid 1980s, was first observed in Haenam-kun, Chonnam in 1991. The disease outbroken throughout the southcoast of Korea caused extremely severe damages and the diseased areas are increasing continuously. The possibility that the bacterial canker was introduced from Japan into Jeju is high, although the path of the epidemic is still not clear. And then the bacterial canker may spread from Jeju to Haenam and/or Wando, from which the disease may spread to the southcoast of Chonnam and the westcoast of Kyungnam in Korea.

A 57-year old man who was admitted to an emergency room of a tertiary hospital with hemoptysis developed malarial fever 19 days later and then died from severe falciparum malaria 2 days later. He had not traveled outside of Korea for over 30 years. Through intensive interviews and epidemiological surveys, we found that a foreign patient with a recent history of travel to Africa was transferred to the same hospital with severe falciparum malaria. We confirmed through molecular genotyping of the MSP-1 gene that Plasmodium falciparum genotypes of the 2 patients were identical. It is suggested that a breach of standard infection control precautions resulted in this P. falciparum transmission between 2 patients in a hospital environment. This is the first report of a nosocomial transmission of falciparum malaria in Korea.

The porcine epidemic diarrhea virus(PEDV) production yield in spinner flask cultures using Vero cells immobilized on microcarriers was improved by the selective adsorption of ammonium ions in a Carberry type bioreactor which was equipped with Phillipsite-Gismondine synthetic zeolite. Though the apparent cell growth seemed to be lower than that of control due to the aggregation of microcarriers between impeller shaft and the adsorbent, zeolite was found to not to be toxic to Vero cell, considering estimated glucose and lactate changes. Zeolite was observed to remove ammonium ions effectively in both steps of cell growth and virus production. In virus production, the virus titer with zeolite was two times higher than that without zeolite. Consequently, zeolite was found to be an ideal adsorbent for higher production of virus vaccine with the effective removal of ammonium ions.

The rapid rise in the incidence of obesity has emerged as one of the most pressing global public health issues in recent years. The underlying etiological causes of obesity, whether behavioral, environmental, genetic, or a combination of several of them, have not been completely elucidated. The obesity epidemic has been attributed to the ready availability, abundance, and overconsumption of high-energy content food. We determined here by Pearson's correlation the relationship between food type consumption and rising obesity using the loss-adjusted food availability data from the United States Department of Agriculture (USDA) Economic Research Services (ERS) as well as the obesity prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) and the National Health and Nutrition Examination Survey (NHANES) at the Centers for Disease Control and Prevention (CDC). Our analysis showed that total calorie intake and consumption of high fructose com syrup (HFCS) did not correlate with rising obesity trends. Intake of other major food types, including chicken, dairy fats, salad and cooking oils, and cheese also did not correlate with obesity trends. However, our results surprisingly revealed that consumption of com products correlated with rising obesity and was independent of gender and race/ethnicity among population dynamics in the U.S. Therefore, we were able to demonstrate a novel link between the consumption of com products and rising obesity trends that has not been previously attributed to the obesity epidemic. This correlation coincides with the introduction of bioengineered corns into the human food chain, thus raising a new hypothesis that should be tested in molecular and animal models of obesity.

Porcine epidemic diarrhea virus (PEDV), an enveloped single stranded RNA virus in the family Coronaviridae, causes acute viral enteric disease in piglets. Recently outbreaks of porcine epidemic diarrhea (PED) have been rare in Europe but frequent in Asia. In Korea, the increase of PED prevalence is showing specially in postweaning pigs. The purpose of this study was to investigate nucleotide sequence of nucleocapsid protein gene of PEDV field isolates from postweaning pigs in Korea and get more information about the viruses. A total of 15 postweaing pigs clinically suspected of PEDV infection by severe watery diarrhea and dehydration were used in this study. Viral RNA was extracted from small intestines and stools of the pigs. The N gene was amplified by nested RT-PCR, purificated, sequenced, analyzed and then compared with published sequences of other PEDV strains. Three PEDVs were isolated from the suspected postweaning pigs. The N gene of three PEDV field isolates consisted of 483 nucleotides. These PEDV field isolates showed nucleotide sequence homology range from 99.6% to 95% with Chinese strains, from 99.8% to 95.2% with Korean strains, from 97.3% to 95.7% with Japanese strains and from 96.5% to 95.7% with Belgium and British strains. The encoded pritein shared range from 98.8% to 95.6% with Chinese strains, from 99.4% to 95% with Korean strains, from 97.5% to 96.3% with Japanese strains, from 95.6% to 95% with Belgium and British strains. By phylogenetic tree analysis based on nucleotide sequence, three PEDV field isolates were clustered into two groups which were Chinese isolate groups and other Korean isolate groups. These results indicated that some of PEDV field isolates prevailing in Korean postweaning pigs may be associated with those of Chinese strains and other Korean strains.

The purpose of this study was to keep the Security Control Center, which operates under a shift system, uninterrupted during the COVID-19 virus epidemic. Security facilities responding to cybersecurity threats are essential security facilities that must be operated 24 hours a day, 365 days a day in real time, and are critical to security operations and management. If security facilities such as infectious disease epidemic, system failure, and physical impact are closed or affected, they cannot respond to real-time cyberattacks and can be fatal to security issues. Recently, there have been cases in which security system facilities cannot be operated, such as the closure of facilities due to the COVID-19 virus epidemic and the availability of security systems due to the rainy season, and other cases need to be prepared. In this paper, we propose a plan to configure a security system facility as a multiplexing facility and operate it as an alternative in the event of a closed situation.
