Purpose: The purpose of this research was to describe clonorchis sinensis infection experience in high risk populations living in riverside areas. The research question was "How do local residents perceive Clonorchiasis and how are they infected with the parasite". Methods: Qualitative data were collected by focus group interviews with 16 participants from January to February, 2009. All the interviews were tape-recorded, transcribed, and analyzed by the content analysis method. Results: Five main categories were conceptualized, which were "lacking in understanding of Clonorchiasis," "culture of the rural community," "life style," "recovering experience from infection" and "change of health behavior." Conclusion: The result of this study indicates that residents are infected with Clonorchiasis through interaction between individual and group risky factors. Therefore, it is important to develop effective health education programs on both individual and group levels to prevent infection with Clonorchiasis.

This study is carried out to understand the characteristic of location in vernacular agricultural villages by judging from natural environment around the village. For this purpose, there were selected 17 villages of the riverside villages in Geosan Area which lean against Dalchoen River. After classifying these samples by the morphorogical approach, according to compare them with pre-researched villages, the methodology of spatial structure was investigated in agricultural villages. As a result of the study, the relationship between the agricultural villages and the shape of Dalcheon River can be classified by 3 types that are twisted around villages, attacked villages, and paralleled with villages. First of all, twisted type is located in river terraces, river safety zone and taken a image of the riverside agricultural village. Secondary, attacked type is located in beside riffle, and taken a image of a fishing village. Finally, paralleled type is located in straightly flowing river.

In an attempt to clarify the epidemiological feature of distomiasis in Tongjin riverside area, the prevalence of distomiasis in the residents and infection rates of the metacercariae in fresh-water fishes were investigated at the upper, middle and lower reaches of the river from January to April, 1984. The results obtained were summarized as follows: 1. Out of a total of 931 fresh-water fishes which composed of 33 different species, 611 fishes(65.6%) of 31 species were found positive with digenetic trematode metacercariae of 16 different species, and there were some differences in infection rates of the metacercariae among the fishes in the 3 parts of the river; 53.8% in upper, 80.7% in middle, and 61.0% in lower reaches, respectively. 2. Infection rates of the metacercariae of Exorchis oviformis, Metagonimus yokogawai, Echinochasmus japenicus, Metorchis orientalis and Clonorchis sinensis in the fishes were 48%,29%, 115, 7.9% and 6.3oA, respectively. 3. The average number of the encysted larvae of Clonorchis found in fish body/gram showed 4.44 in Pseudorasbera larva, Gnathepegon coreanus (1.2), Microphysogoio yaluensis (0.76), Abbottina springeri (0.4), Acanthorhodeus asmussi (0.21) and Cultriculus eigenmanni (0.17), respectively. 4. The average number of the metacercariae of Metagonimus found in fish body/gram disclosed 34.01 in Zacco platypus, Zacco temmincki (16.46), Carassius carassius (5.35), Moroco oxycephalus (1.54) , Aphyocypris chinensis (1.5) and etc., respectively. 5. Detection rates of the eggs of Clonorchis and Metagonimus among residents were 1.1% and 0.8%, respectively, out of a total 923 Persons.

Purpose: In order to lower the infection rate and the reinfection rate of Clonorchiasis in high-risk areas, we performed and analyzed a case management on people with chlonorchisis. Methods: The data was collected from April 2010 to March 2011. A community health practitioner was selected as a case manager based on our training program. The intervention group had 58 participants with three months of case management and the control group had 144 participants handled with traditional methods. Results: the pre and post-test in the intervention group and the control group showed us improved knowledge of Clonorchiasis, attitudes and behavior toward eating freshwater fish. The results of post-test between the intervention group and the control group showed statistically significant differences in all categories, except a hand-washing category. However, one year after a case management, there was no significant difference in the failure rate of treatment. Conclusion: The case management was effective for people infected with Clornorchiasis near riverside areas; however, in order to lower the rates of reinfection and treatment failure, it is necessary to perform continuous monitoring and regular evaluations.

1) Lee-Su village is located in a riverside of an upper Tu-men river. Since an upper stream of Tu-men river is narrow and easy to pilot a boat, early in the past, it facilitated the form of the village near to the North Korean. 2) The form of the village is parabolic from the founding period. That is, increasing the number of houses in the time of the Cultural Revilution Campaign, and the Japanese colony, the village has transformed into the bigger size about 72 families from the small town. After the cultural revolution, due to private asset allowed in accordance with the Chinese Reform and Open Policy, the number of families in the town and the population have been decreased. As a result, 28 families live in the village currently. 3) The town which was well-ordered in the Japanese colonial period has been changed to a very disordered and agricultural town, owing to the decrease of the families A road system has been also ruined naturally in accordance with the decline of the number of the families.

Comprehensive development projects were carried out on the Han River from 1982 to 1986 for the purpose of creating a more serviceable places such as a riverside parks and autoroads and so on. However because of the river development, river ecosystem and function were destroyed. And many local autonomous entity follows comprehensive development projects as if it is a model case. To investigate the impact that the river development effects the river ecosystem, two sites which are Anyangcheon and Sooipcheon were surveyed in the right of around plants ecosystem and structure. Two sites are creek of the Hna River. Sooipcheon maintains the sound ecosystem. It has sufficient carrying capacity for the river recreation activity. The reason is that a hydrophyte absorbs nutrients from the stream and the river ecosystem meets the around terrestrial one neturally. Number of hydrophyte increase from upstream going forward to downstream. Number of hydrophyte increase from upstream going forward to downstream. Anyangchoen is seriously polluted stream out of many branch stream of the Han river. In the upstream various woody plants and hydrophyte appeared. But from the river developed area at midstream, naturalized plants dominated such as Bidens tripartita, panicum dichotomiflorum etc. To manage the creek ecologically, hydrophyts were introduced in partly for natural purification after rehavilitate the riverside, and steadily monitoring is demanded.

Hydraulic conductivity is an important parameter, representing permeable property of the groundwater in aquifers, in the issues of groundwater development, groundwater contamination, and groundwater flow, etc. We estimated a relationship between hydraulic conductivity and electrical properties (formation factor, chargeability, and time constant) of silty sand in the laboratory. For this study, we conducted grain size analysis, constant head permeameter test, and measured electrical resistivity and spectral induced polarization of silty sand samples collected from the riverside alluvium of the Nakdong River in Nogok-ri area, Dasan-myeon, Goryeong-gun in Gyeongbook Province, Korea. In the laboratory test, we used soil samples of approximately uniform porosity with 0.5% error range, and kept the electrical resistivity of pore water with 100 ohm-m. As a result, the relationship between effective particle size and hydraulic conductivity agrees fairly well with the existing empirical formulas. Hydraulic conductivity was correlated with formation factor, chargeability, and time constant: hydraulic conductivity increased with increasing formation factor and time constant as well as with decreasing chargeability.
