Two human cases of Heterophyes heterophyes and H. dispar infections were proven by the recovery of their adult worms. The cases were 38-year and 40-year old Korean workers who had been in Saudi Arabia for 4~6 years and returned home in 1983 or 1984 with gastrointestinal troubles. In Saudi Arabia they had eaten raw brackish water fishes such as the mullet. After the treatment with 10 mg/kg praziquantel and purgation with magnesium salt, a total of 19 specimens of H. heterophyes and 140 of H. dispar were collected. It is of interest that the worms persisted in a patient although he had been back in Korea for 14 months. This is the first report on imported heterophyiasis in Korea. Human infection by H. dispar is the first record in the literature.

Pulpal temperature is changed in response for various conditions which were mechanical, thermal, chemical and biological stimuli. This study was performed to determine the pulpal temperature changes which were using air turbine with air-water coolant, water coolant, and conventional dental engine with water coolant and no coolant on 28 canine of dogs. In order to record pulpal temperature, pulp chamber was opened on the labiocervical area of canine. Thermocouple was inserted into pulp chamber and was fixed with filling material(dycal). Changes of pulpal temperature were recorded on the physiograph, which had been standardized temperature degree, through thermocouple to thermistor bridge and carrier preamplifier. The amount of experimental temperature change to that of control was interpreted in the pulpal cavity. The obtained results were as followings: 1. The mean normal temperature was 33.07 centigrade. 2. The temperature was decreased than normal pulpal temperature. It was 12.04 centigrade in reduction by air turbine with air-water coolant, 7.17 centigrade in reduction by air turbine with air coolant, 5.54 centigrade in reduction by conventional engine with water coolant, and 1.26 centigrade in reduction by conventional engine with no coolant. 3. The time for maximal temperature change was 53.3 seconds in reduction by air turbine with air-water coolant, 73.4 seconds in reduction by air turbine with air coolant, 50.9 seconds in reduction by conventional engine with water coolant, and 27.1 seconds in reduction by conventional engine with no coolant. 4.. After reduction was ceased, the recovery time to normal pulp temperature was 287.1 seconds in air turbine with air-water coolant, 189.0 seconds in air turbine with air coolant, 86.9 seconds in conventional engine with water coolant, and 52.9 seconds in conventional engine with no coolant respectively.

Fecal examinations using the Kato Katz technique were performed on a total of 1,287 villagers (945 students and 342 general inhabitants) of Oddar Meanchey Province, Cambodia in May 2007 and November 2009. The overall intestinal helminth egg positive rate was 23.9%, and the most prevalent helminth species was hookworms (21.6%). Other helminth eggs detected included echinostomes (1.0%), Enterobius vermicularis (0.8%), small trematode eggs (0.7%), which may include Opisthorchis viverrini and Haplorchis spp., and Hymenolepis nana (0.4%). In order to recover adult echinostomes, we treated 2 patients with 10-15 mg/kg praziquantel and purged. Total 14 adult echinostomes, 1 and 13 worms from each patient, were collected. The echinostomes characteristically had 49-51 collar spines and 2 round or slightly lobated testes. They were identified as Echinostoma ilocanum (Garrison, 1908) Odhner, 1911. So far as literature are concerned, this is the first record on the discovery of human E. ilocanum infection in Cambodia.

Objectives: The aim of this study was to identify the causal relationship between use of levocetrizine or cetrizine, and liver injury, by comparing frequency and pattern of hepatotoxicity in levocetrizine or cetrizine prescribed patients. Methods: This is a retrospective observational study, using data retrieved from electronic medical record system. Among 1164 patients prescribed levocetrizine or cetrizine during study period (Jul, 2009 - Jun, 2010) at Seoul National University Hospital, 543 patients with more than 4- time liver function test (LFT) results were included in final analysis. Liver injury was defined as greater than 3 times elevated level of alanine aminotransferase or 2 times elevated level of alkaline phosphatase or total bilirubin, compared to upper limit of normal, in patient with normal liver function at baseline. The frequency and pattern of liver injury were assessed. Results: Incidence of liver injury in patients prescribed with levotcetrizine or cetrizine were 1.48% and 2.94%, respectively. With few exceptions, most injuries were shown to be hepatocellular type. Rapid recovery was observed after drug cessation and long term use tends to be associated with incidence of liver injury. In patient with digestive system disorder, rate of liver injury was significantly higher (p=0.011). Conclusion: The result of this study implies potential need of liver toxicity monitoring, especially in patients taking long term levecetrizine or cetrizine or in patient with digestive system disorder. However, prospective large scale observational study is needed to confirm liver injury associated with the use of levocetirizine or cetirizine.

Forest fire is a critical disaster that causes massive destruction of forest ecosystem and economic loss. Hence, accurate estimation of the burned area is important for evaluation of the degree of damage and for preparing baseline data for recovery. Since most of the area size damaged by wildfires in Korea is less than 1 ha, it is necessary to use satellite or drone images with a resolution of less than 10m for detecting the damage area. This paper aims to detect wildfire-damaged area from a Kompsat-3 image using the indices such as NDVI (normalized difference vegetation index) and FBI (fire burn index) and to examine the classification characteristics according to the methods such as Otsu thresholding and ISODATA(iterative self-organizing data analysis technique). To mitigate the salt-and-pepper phenomenon of the pixel-based classification, a gaussian filter was applied to the images of NDVI and FBI. Otsu thresholding and ISODATA could distinguish the burned forest from normal forest appropriately, and the salt-and-pepper phenomenon at the boundaries of burned forest was reduced by the gaussian filter. The result from ISODATA with gaussian filter using NDVI was closest to the official record of damage area (56.9 ha) published by the Korea Forest Service. Unlike Otsu thresholding for binary classification,since the ISODATA categorizes the images into multiple classes such as(1)severely burned area, (2) moderately burned area, (3) mixture of burned and unburned areas, and (4) unburned area, the characteristics of the boundaries consisting of burned and normal forests can be better expressed. It is expected that our approach can be utilized for the high-resolution images obtained from other satellites and drones.

Four cases of human infection by Echinochasmus japonicus (Trematoda; Echinostomatidae) were proven by the recovery of adult worms after a treatment with praziquantel (10mg/kg in single dose) and purgation in February 1984 in Korea. The patients were 3 middle-aged men and 1 elderly woman residing in a riverside village of Kangjin-gun (Tamjin river), Jeonranam-do, an ever-known endemic area of metagonimiasis. The treatment revealed numerous M. yokogawai worms together with 1-43 (total 54) specimens of E. japonicus and/or a few number of other kinds of trematodes or cestodes. The patients had gastrointestinal troubles such as indigestion and abdominal discomfort, probably due to these fluke infections. They have been eating some raw flesh of fresh water fishes such as cyprinoid ones or sweet fish caught from the river. This is the first record of human E. japonicus infection in the literature.

Objectives : The aim of this study is to evaluate possibility of DITI as prognosis evaluation tool of facial palsy. Methods : We investigate prognosis of facial palsy through EMR(Electronic Medical Record) of inpatient from December 2016 to June 2017. We evaluated the sex, age distribution, length of hospital stay, paralysis site, number of treatment after discharge, change of H-B Grade at entrance and exit, temperature difference of both sides of DITI, and Nerve Conduction Study(NCS) with reference to EMR recorded symptom change. Results : 1. Significant correlations were not found between DITI and House-Brackmann Grade change, NCS(%), the date of admission. 2. There was a negative correlation between NCS(%) and hospitalization period in patients with facial palsy. The higher the NCS, the faster the recovery rate of facial palsy. 3. In patients with facial palsy, the temperature difference between the two sides after the DITI image shows that the affected side tends to be lower than the normal side. Conclusions : In this study, only DITI temperature difference between both sides of face is not significant in determining the prognosis of facial palsy. Further research is needed to conduct DITI at the same time and to improve accuracy through a sufficient assessment of the degree of facial palsy.

A cohort was established for evaluation of cancer risk factors in Sancheong-gun, Gyeongsangnam-do, Korea. As one of the cohort studies, stools of 947 residents (403 males and 544 females, age range: 29-86 years) were screened for Clonorchis sinensis eggs using both Kato-Katz method and formalin-ether sedimentation technique. The overall egg positive rate of C. sinensis was 37.7% and individual EPG (eggs per gram of feces) counts ranged from 24 to 28,800. Eight egg positive residents voluntarily joined a process of collection of the passed worms after praziquantel treatment. A total of 158 worms were recovered from 5 of the 8 treated persons, ranged from 3 to 108 in each individual. The worms were $15-20 mm{\times}2-3 mm$ in size, and showed brown-pigmented, red, or white body colors. This is the first collection record of C. sinensis adult worms from humans through anthelmintic treatment and purgation. The adult worms of C. sinensis may be paralyzed by praziquantel and then discharged passively through bile flow in the bile duct and by peristaltic movement of the bowel.

Medicinal porridge (藥粥) is made by putting rice or grains into a pot and boiling with water until a semi-liquid texture is obtained. Porridge is digested fast and absorbed by the body. Children or elderly people with weak digestive ability can eat it without difficulty. The authors of this literature focused on utilization of mung bean porridge (Nokdu-juk) based on SeungjeongwonIlgi (承政院日記), which is the daily record of the Royal Secretariat of the Joseon Dynasty from 1623 to 1910. Four cases were found. The first case used mungbean for treating fever diseases (熱症), the second as a meal alternative, the third for wound recovery, and the last case described the culture of the joseon dynasty. According to the actual cases in SeungjeongwonIlgi (承政院日記), mung bean porridge (Nokdu-juk) was actively used to lower fever and strengthen the spleen and stomach. When suffering from the after effects of a malignant tumor or serious liver disease (肝病), an infectious disease, or a serious physical wound, people ate mung bean porridge (Nokdu-juk). It is suggested that mung bean porridge (Nokdu-juk) can be used as an alternative food treatment for the current medical field due to the prevalence of pain-killers and psychotropic drug abuse.

Ecomuseum which appeared in France in 1968 and widely diffused over the world, is a new type of museum. The purpose of this museum is not to simply possess and exhibit the existing relics, but to discover the locational senses of a territory by in-situ conserving and interpreting its entire natural and cultural heritages, and to plan the participation of its population and the development of its local community. The significance of this museum can be found in the recovery of disappearing collective memories of a territory, the restoration of the cultural identity of its population and the revitalization of a underdeveloped area. As the majority of these museums are fragmented or open air museums, an 'web ecomuseum' which makes the remote offering of informations about whole dispersed heritages and their holistic interpretation possible by digitalizing, recording, conserving, interpreting and utilizing related heritages, is necessary. This paper considers the possibility of web ecomuseum and its constitution contents and methods through the case of Mountain Mudeung area. Especially, in relation to the latter, this paper suggests a plan which consists of selection of own local themes, construction of digital archives, design of web expositions and production of electronic cultural maps.
