Opisthorchis viverrini is still a serious problem in Northeastern and Northern Thailand. Active surveillance is required to determine updated data for further prevention and control planning. Therefore, this study aimed to examine the prevalence and risk factors for O. viverrini in three provinces, Northeastern Thailand. A cross-sectional survey was conducted during October 2015 to March 2016 at Kaeng Sanam Nang district of Nakhon Ratchasima province, Waeng Noi district of Khon Kaen province, and Khon Sawan district of Chaiyaphum province, Thailand. Stool samples were examined by using a modified Kato-Katz Thick smear technique. From a total of 978 participants screened, O. viverrini infection was found in 1.74%, the majority opf positive cases being male (6.62%), age group 51-60 years old (4.21%), educated at primary school (8.43%), occupied with agriculture (9.62%),having an income <4,000 baht per month (4.82%), and living in Khon Sawan district (8.43%). Participants had a high knowledge level (42.43%), good attitude level (34.76%), and fair level (38.04%). The present study indicates the O. viverrini infection rate is low, but elderly males with primary school education involved in agriculture are still frequently effected particularly in Khon Sawan district. Therefore, this risk group requires behavior modification and continued monitoring.

To clarify the reinfection profile associated with risk factors of opisthorchiasis, we conducted an epidemiological study on the chemotherapeutic effects on reinfection with O. viverrini in the endemic areas of Northeastern Thailand for 3 years. A total of 3,674 fecal samples were collected from participants in villages of 5 provinces. They were examined microscopically using a modified technique of formalin ethyl-acetate concentration. Egg-positive residents were reexamined year (2018) by year (2019) after treatment with a single dose (40 mg/kg) of praziquantel. Health education was provided to the participants yearly. The egg-positive rate of O. viverrini was 14.3%, and was highest (22.2%) in the 20-30 year-old group in 2017. The egg positive rate was 15.3% in dogs and 11.4% cats. Human reinfection rate was 15.5% and 6.3% in next 2 years, and was highest (23.2%) among the fishermen. Relative risk factors of reinfection were significantly higher for males, over 40-year-old age, or working as fishermen or farmers, and eating uncooked fish within the preceding year. A significant difference resulting from a health education program was observed in the third year. Therefore, health education and sustainable surveillance for opisthorchiasis should be maintained to decrease the risk of reinfection.

This paper tries to explore the local uniqueness and evolutionary characteristics of the spatial structure of the rural dwelling houses of China's Korean Ethnic. For this purpose, the paper selected 51 typical samples in each district, analyzing their ancestral home, building age, size, construction method, family composition etc. Moreover, the paper classified the pattern of the samples and analyzed the characteristic and evolutionary process of each pattern. Conclusions based on the analysis of the ancestral homes are as follows: 1.The house pattern of these China's Korean ethnics who are originally from the Hamkyung province is mainly jeongji- access type (A-type). A-type is mainly distributed along the Tumen River and Yalu River, in the Sino-Russian borders and the inland areas of Heilongjiang province. With the migration of the China's Korean ethnics, in Sino-Russian borders and the inland areas of Heilongjiang province, A-type with the 'badang' space, vestibule-access type (C-type) and living-centered type (D-type) appeared. 2. House patterns of Korean ethnics who are originally from the Pyongan province include three types: A-type, kitchen type (B-type) and C-type. A-type is mainly distributed along the Yalu River while B-type and C-type are mainly in the inland areas of these three Northeast provinces. With the decrease of population, the merger of rooms happened in A-type; while in the B-type and C-type, bathroom and storage came to exist in the north of the room. 3. The house pattern of Korean ethnics who are originally from the Gyeongsang province is mainly B-type, which is distributed in the inland areas of Heilongjiang and Jilin provinces. Besides, C-type and D-type also exist. They are in Jilin and Liaoning provinces. In the process of evolution, storage was set in the north part of the room or the window was cancelled in order to defend the coldness in Heilongjiang area, while in Jilin and Liaoning provinces, living room came into existence, which is gradually developing to D-type.

Journal of the Korean Society of Clothing and Textiles Vol. 21, Nt. 5 (1997) p. 865∼879 The purpose of the study is to identify a historical change about the women's underwear and trousers this nation of ours until an ancient times to modern ages. Because the record of the women's trousers exist scarcely anything, the study refers to several documents, for example, the literatures of the Chinese and the Chosun Dynasty, the Koryu's fresco, the Tou of Shinra, the painting of the rock face, the archaeological dresses and genre pictures, and The folkways methods through the residents is used to collect and to arrange of an enlightened age and modern times. Originally, the women's trousers appeared for the nomadism and the hunting in the northern distric and the northeastern provinces. Male and female, old and young wear the trousers which are the clothes native to Korea. The trousers which are originally narrow trousers are influnced by Chinese wide trousers. The trousers at the time of Samsuk hand down until Korea. The Skirt on the trousers is nothing but a courtesy. But gradually, it is distinguished only the trousers, and then, there are exchanged an underwear which not only the protection angainst the cold but also the beautiful. Therefore, the form of skirt is diminished, and the underwear is simplified as the increasing status and the activity of woman in the age of civilization. In a way, the reform trousers and Three-kingdom era trousers appeared and the Dansogok and Sogok disappeared at present. There are confirmed in my investigation of folk customs.

The central region of South Korea is composed of Precambrian formations and Jurassic Daebo granites and is divided tectonically into three provinces, that is, the Ok chon geosynclinal zone in the middle, the Kyonggi massif on the north and northwest side, and the Ryongnam massif on the south and southeast side. The general trend of the Okchon geosynclinal zone and the distribution of Daebo granites is northeast, the Sinian direction. The Kyonggi massif is composed of Precambrian Y onchon system, Sangwon system, gneisses, and Daebo granites, and the Ryongnam massif also Precambrian Ryongnam and Yulri systems, gneisses, and Daebo granites. Precambrian formations in both areas are of flysch type sediments and may be roughly correlated with each other. These formations except Sangwon and Yulri systems are thought to be early to middle Precambrian age and have acted as basement for the Okchon geosyncline where late Precambrian Okchon system was deposited. The Okchon geosynclinal zone is divided into paleogeosynclinal zone to southwestern parts where the Okchon system is distributed, and neogeosynclinal zone to northeastern parts where nonmetamorphosed Paleozoic sediments are dominantly cropped out. Both zones are separated by upthrust created by Daebo orogeny of Jurassic period, which continues southwesterly to bind the Okchon geosynclinal zone and the Ryongnam massif at southwestern parts bisecting Korea peninsula diagonally. Three periods of structural development are recognized in the area. Folds and faults of preTriassic age prevail in the Kyonggi massif. Many isoclinal folds and thrusts originated by Jurassic Daebo orogeny are aligned in the Okchon paleogeosynclinal zone paralleling to the geosynclinal axis so that same formation appears repeatedly in narrow strips, whereas fold axis in neogeosynclinal zone trerid west-northwesterly which might be of Triassic in age and modified by later Daebo orogeny. Discontinuity of geology and structure of Okchon geosynclinal zone is attributed to shifting of the geosyncline through geologic time.
