Epidemic malaria is prevalent in the demilitarized zone and the northern area of Kyonggi province in Korea. Malaria has broken out in Gangwha-Gun since 1997 due to geographical condition. The results obtained from an epidemiological surveillance for the malaria that happened in 1999 were as follows ; Anopheles sinensis collected in UV-light traps in the barn in Wolgogri and Dangsanri of Songhaemyon showed the distribution of 27,156 of 49,280 figures, corresponding to 55.1%, between July and August. The numbers of patients with malaria were 48(32.4%) in July, 36(24.3%) in August, and 38(25.7%) in September with a prevalence with the ages of the twenties to the seventies. Of a total 154 patients, the male were 86(58.1%) and the female were 68(41.8%). The annual parasite index(API) were 6.44, 5.89 and 4.45 in Songhaemyon, Yangsamyon and Kyodongmyon, respectively. A high infection rate was found Particularly in the areas within 2km from the Han river. By the immunofluorescence assays(IFA), 26 cases were positive with an antibody titers of $\geq$ 1 : 32, of 220 residents in Songhaemyon and 336 ones with a potential case and contacted with the patients. By the blood test, there was no significance in alkaline phosphatase, alanine aminotransferase, total cholesterol, glucose, hemoglobin, hematocrit, white blood cell, red blood cell, and platelet between residents with an antibody titers of $\geq$ 1 : 32 and < 1 : 32 in Songhaemyon.

Byeon Jeung[辨證], which is to differentiate symptoms is a process of assessing the patient's condition. And like any other differentiation system, a ceratin pathological perspective is embedded. In Onbyeonghak(溫病學), new Byeon Jeung systems were designed to complement the insufficient, existing perspectives on acute epidemic febrile diseases. Oguktong(吳鞠通)'s Samchobyeonjeung(三焦辨證) is one of these newly designed systems. Though the meaning of Samchobyeonjeung varies among Onbyeong(溫病) researchers, they stand on common grounds of differentiating damp-heat disease[濕熱病]. However, Oguktong(吳鞠通) clearly demonstrated this system on epidemic febrile diseases. Researchers have acknowledged the importance of Oguktong(吳鞠通)'s approach, but thorough analysis of the subject has been insufficient. In this study, I have primarily studied the meaning of Samchobyeonjeung by analyzing "Onbyeongjobyeon(溫病條辨)", followed by assessment of negative and positive aspects.

Purpose: This study aims to examine how elementary, middle and high school health teachers in Gyeonggi province react to infectious disease like MERS. Methods: This is a descriptive study using a convenience sample of 1,267 school health teachers. Results: When MERS was an epidemic, school health teachers who took the 'leading' role were 92.4%. A school heath teacher's countermeasures against infectious diseases showed a high score during MERS outbreak (3.81) compared to regular days (3.59). Conclusion: Based on such results, it has been determined that schools need to keep two types of procedures manual, such as 'countermeasures on a regular basis' and 'countermeasures in the event of a pandemic disease outbreak' manual in the staff offices so that anyone can view them at any time. It is necessary to prepare regulations to strengthen their authority so that school health teachers can take the role of control tower, in a professional capacity, when communicable disease is spreading. In order to prevent any confusion and chaos, there should be a unitary reporting system at each school when dealing with an epidemic. School health teachers need to get continuous training to reinforce their abilities to react to communicable diseases.

$^{131}I$-labeled-O-iodohippurate renograms in 15 cases of epidemic hemorrhagic fever(E.H. fever)during oliguric, diuretic and convalescent phase were analysed quantitatively and qualitatively, namely by its configuration, Tmax T 1/2 and renal index of Hirakawa. The results were as following: 1) Changes on the renograms in E.H. fever showed simultaneous bilateral renal impairment. 2) The characteristic configurations of renogram in the oliguric phase were: (1) Moderately decreased absolute amplitude of initial spike. (2) Continous rising second slope. (3) No appearance of terminal descent. Those were mast likely to those of renograms in acute ureteral obstruction or acute dehydration state. 3) During the diuretic phase, the renogram showed the point of maximal amplitude, but the steepness of 2nd slope was markedly decreased. The appearance of terminal descents was observed with unusually high amplitude despite of the tremendously large amount of urinary output during this phase. 4) In convalescence, the renograms were essentially normal in configuration, but the renal index of Hirakawa was not recovered until this phase. 5) Renograms in E.H. fever showed the characteristic patterns in each phase of its clinical course. 6) $^{131}I$-OIH-Renogram might be an useful method for the evaluation of renal function in E.H. fever during its course.

Paederus dermatitis caused by the contact of staphylinid beetles(Paederus fuscipes) body fluid(pederin) is characterized by linear erythematous vesicopustular lesions. An outbreak of dermatitis occurred at apartments located at the river side after rainy season in summer 1994. Authors surveyed 189 cases(94 males and 95 females) from 103 households reported at the apartment office in Kimcheon on September 1994. The results are as follows; 1. The causative agent of skin diseases was identified as Paederus fuscipes. 2. The attack rate of paederus dermatitis was 52.6% by households, and the residents in the middle floors of the apartments were attacked more frequently than those in other floors. All ages were affected. 3. The skin lesions developed by paederus were distributed on face(38.2%), neck(18.5%), shoulder and trunk(11.0%), arm and leg(10.3%), and back(6.6%). In 21 cases(15.4%), skin lesions were developed in multiple sites. 4. The apartments attacked by paederus was located near the sand and damp soil along the bank of the river. The fodder cultivating farm was located near the upper reaches of river, and a rice field and grape garden in the backyard of the apartment.

A new method to calculate the transmittable prevalence of an epidemic disease is proposed based on a back-calculation formula. We calculated the probabilities of reactivation and of parasitemia as well as transmittable prevalence (the number of persons with parasitemia in the incubation period) of malaria in South Korea using incidence of 12 years(2001-2012). For this computation, a new probability function of transmittable condition is obtained. The probability of reactivation is estimated by the least squares method for the back-calculated longterm incubation period. The probability of parasitemia is calculated by a convolution of the survival function of the short-term incubation function and the probability of reactivation. Transmittable prevalence is computed by a convolution of the infected numbers and the probabilities of transmission. Confidence intervals are calculated using the parametric bootstrap method. The method proposed is applicable to other epidemic diseases in other countries where incidence and a long incubation period are available. We found the estimated transmittable prevalence in South Korea was concentrated in the summer with 276 cases on a peak at the $31^{st}$ week and with about a 60% reduction in the peak from the naive prevalence. The statistics of transmittable prevalence can be used for malaria prevention programs and to select blood transfusion donors.

The impact of the next influenza pandemic is difficult to predict. It is dependent on how virulent the virus is, how rapidly it spreads from population to population, and the effectiveness of prevention and response efforts. Despite the uncertainty about the magnitude of the next pandemic, estimates of the health and economic impact remain important to aid public health policy decisions and guide pandemic planning for health and emergency sectors. Planning ahead in preparation for an influenza pandemic, with its potentially very high morbidity and mortality rates, is essential for hospital administrators and public health officials. The estimat ion of pandemic impact is based on the previous pandemics- we had experienced at least 3 pandemics in 20th century. But the epidemiologi cal characteristics - ie, start season, the impact of 1st wave, pathogenicity and virulence of the viruses and the primary victims of population were quite different from one another. I reviewed methodology for estimation and modelling of pandemic impact and described some nations's results using them in their national preparedness plans. And then I showed the estimates of pandemic influenza impact in Korea with FluSurge and FluAid. And, I described the results of pandemic modelling with parameters of 1918 pandemic for the shake of education and training of the first-line responder health officials to the epidemics. In preparing influenza pandemics, the simulation and modelling are the keys to reduce the uncertainty of the future and to make proper policies to manage and control the pandemics.

Porcine epidemic diarrhea virus (PEDV) strain Chinju99, which was previously isolated from piglets suffering from severe diarrhea was used to characterize the membrane (M) protein gene to establish the molecular information, and the results will be useful in elucidating concepts related to molecular pathogenesis and antigenic structures of PEDV isolates. The Chinju99 M gene generated by reverse transcription and polymerase chain reaction (RT-PCR) consisted of 681 bases containing 22.3% adenine, 22.3% cytosine, 23.1% guanine and 32.3% thymine nucleotides, and the GC content was 45.4%. It had some nucleotide mismatches from M gene of other PEDV strains, such as CV777, Br1/87, KPEDV-9, JMe2, JS2004-2 and LJB-03 with 97-99% nucleotide sequence homology to these strains. Also, it encoded a protein of 226 amino acids, which had some mismatches from those of CV777, Br1/87, KPEDV-9, JMe2, JS20004-2 and LJB-03, as the amino acid sequence homology showed a 97-98% to these strains. The Chinju99 had a very close relationship to the Japanese strain JMe2 for the nucleotide and amino acid sequences of the M gene. The amino acids predicted from Chinju99 M gene consisted of mostly hydrophobic residues and contained three potential sites for asparagine (N)-linked glycosylation, two serine (S)-linked phosphorylation sites by protein kinase C, and two S- or threonine (T)-linked phosphorylation sites by casein kinase II.

To provide information for the molecular pathogenesis and antigenic structures of Korean isolates of porcine epidemic diarrhea virus (PEDV), the small membrane (sM) protein gene of Chinju99 strain, which was previously isolated from piglets suffering from severe diarrhea was characterized and further analyzed with other PEDV strains. The sM gene of Chinju99 generated by reverse transcription and polymerase chain reaction had a single open reading frame with 231 bases consisting of 24.2% adenine, 18.6% cytosine, 18.1% guanine and 39.0% thymine nucleotides. Nucleotide sequence of the gene revealed 97.8% homology to those of Belgian strain CV777 and British strain Br1/87, and 97.0% to Chinese strain LZC. The gene encoded a protein with 76 amino acids, and putative amino acid sequence of the gene revealed 98.7% homology to those of CV777 and Br1/87, and 96.1% to LZC. The amino acids of Chinju99 sM gene consisted of mostly hydrophobic residues, and there were one potential N-myristylation site and one potential threonine (T)-linked phosphorylation site recognized. Also, there was a transmembrane region with 46 amino acids, and Chinju99 was more close to CV777 and Br1/87 than to LZC in phylogenetic analysis on the sM amino acid sequences.
