We investigated the prevalence of canine brucellosis in companion and stray dogs between March 2015 and December 2016 and determined the disease characteristics based on the geographic distribution, sex and age of the dogs in South Korea. We conducted a large-scale survey using serological and bacteriological tests. Samples were collected from 2,394 dogs (1,825 companions and 569 strays). Thirty (1.3%) samples were positive for Brucella canis antibodies including 16 (0.9%) from companion dogs and 14 (2.5%) from stray dogs. Two (1.0%) of the 196 samples cultured from the stray dogs were positive. When compared with male dogs, the female companion and stray dogs had a significantly higher prevalence of brucellosis. Moreover, the prevalence of canine brucellosis was significantly higher in stray dogs older than 6 years and the prevalence of the disease in companion dogs was highest in Incheon (2.1%) and Jeolla (2.1%) provinces. Stray dogs from the Daejeon metropolitan area had the highest prevalence of brucellosis (7.9%). National control measures for canine brucellosis have not previously been implemented. Our findings suggest that appropriate screening tests and control measures are necessary to improve the health of dogs and to protect public health in Korea, particularly with the rapid growth of the companion animal industry.

Actinomyces are Gram-positive, non-acid-fast, anaerobic or microaerophilic filamentous bacteria. These organisms are frequently detected from infected root canals and periapical lesion. The purpose of this study was to use indirect immunofluorescence to determine the prescence of select Actinomyces species in a survey of teeth associated with periapical lesion, to clarify the relationship between clinical symptoms of periapical lesions and the Actinomyces species and to study on the cross reaction among Actinomyces. Actinomyces israelii serotype I (ATCC 12102), Actinomyces israelii serotype II (ATCC 29322), Actinomyces viscosus serotype II (ATCC 19246), Actinomyces naslundii serotype I (ATCC 12104) were cultured in anaerobic condition. Rabbit antisera were prepared by intravenous injection of formalized whole cells. Indirect immunofluorescence method was used to achieve the purpose. The following results were obtained. 1. There was a relationship between Actinomyces and periapical disease. 2. A. israelii serotype I, II were frequently identified with Indirect Immunofluorescence and most often assosiated with periapical disease. In culture finding, there was no significant difference between each group. 3. Indirect Immunofluoresence is both more sensitive and more rapid than culture for identification of Actinomyces species in patients with periapical lesion. 4. A. israelii serotype I, II was highly isolated in infected root canals with local swelling, A. naslundii serotype I was highly isolated in those with foul odor, and A. israelii serotype I was found in higher frequncy in those with exudate than other bacteria. 5. In the Indirect Immunofluorescence (1 : 320), A positive cross reaction was obtained between A. israelii serotype I and A. israelii serotype II, also, A. viscosus serotype II and A. naslundii serotype I. There was no cross reaction between A. israelii serotype I, II and A. viscosus serotype II, A. naslundii serotype I.

Purpose: Infection with human immunodeficiency virus (HIV) remains a major global threat, and although the prevalence is comparatively still very low, the number of HIV-positive Koreans is increasing. However, there are no official guidelines as to how to treat people living with HIV/acquired immunodeficiency syndrome (AIDS) (PLWHA) or how to screen for potentially infectious people. This study assessed the level of knowledge and attitudes of dentists in Korea toward PLWHA, and their attitudes to screening patients for HIV infections. Methods: A cross-sectional prospective survey targeting dentists working in Korea was conducted using a self-administered questionnaire. Results: A satisfactory level of knowledge about HIV/AIDS and a relatively positive attitude toward PLWHA was found. Most of the respondents preferred rapid HIV testing using oral fluid as a specimen. The general attitude of dentists toward HIV/AIDS is sufficiently positive to enable provision of the best treatment to the patients in need. Conclusions: Most of the dentists require HIV testing in dental clinics. In spite of their needs, there are several obstacles. It is hoped that financial considerations and official legal requirements related to HIV testing strategies will be considered.

In the 1960s, rapid urbanization and industrialization created the social atmosphere of individualism in Korea. Individualism has weakened social ties, led to the breakdown of communities, and caused various social problems. So, the paradigm is shifting to a shared society and there are moves to seek ways to solve social problems through community. As part of the initiative, the value and importance of common space in multi-unit dwelling, the typical Korean housing type, is increasing. Thus, the purpose of this study is to identify the trends of domestic research about common space, to assess the current state of domestic academic world and explore the future plans of the common space. The content analysis method was mainly used and statistics were additionally used to analyze 172 preceding research. As a result, research on common spaces showed a steady increase to the current time. And research was being diversified in the field of publishing journals, research contents, research methods and facilities. Until now, most studies have focused on improvement of plan and the quality of common space by identifying the attitude survey, space planning, and the actual situation. Thus many more studies about proper way to operate and manage common space need to be conducted. it is considered that the common space will develop more efficiently. The study is expected to be used as groundwork for the development of the common space and serve as concrete data to show future development directions.

Land development policy in Korea, characterized by its supply-oriented policy, has driven rapid economic development. However, it has a negative impact on the natural environment across the country. Especially, as the introduction of quashi-farmland system with the deregulation of agricultural land development in the late 1990s, numerous unfavorable landscape features such as road, motels and apartment have emerged in the rural area. As those interfered irreversible rural landscapes have been expanded, the demand for well preserved rural landscapes have been increased. The objectives of this study, thus, is to suggest the mitigations between the land development and conservation of natural landscape. As such, this study examines the recognition of current rural landscape management status through 118 students with two groups of landscape architecture majored (50 people) and non-landscape majored (68). Both group express the negative impression of current rural landscape management system in general and they pointed out the major landscape problems are caused from inappropriate land use. However, in detail those two groups respond differently, for example, the first group selected the damaged landscape is the second cause of the landscape problem, while the other group selected the poorly maintained settlements. Based on the analysis of the survey, this study suggests 3 recommendations in order to improve the sustainable rural landscape as establishing the proper rural land use planning system, building local governments' capacity to actively participate in the rural landscape management, and preparing the landscape management plans considering area distinctive characteristics.

Rural house came into the rapid change through the process of modernization and Saemaul movement in the past. This change continue to the current era, there is a such exotic forms and indiscriminate development of new house and Saemaul housing and existing conventional farmhouse in rural area. Such a phenomenon, ultimately creating disharmony in traditional environment of rural. In this respect, reflecting the location characteristics of the region which is based on the regional characteristics and unique model of rural housing, it is absolutely required for the development of rural housing customized to fit the diversity of modern. With that background, the purpose of the research is to try and find out the changes in rural houses and the transforming characteristics. To achieve this research purpose, this research selected a specialized magazine for architecture. Then, it identified contents which has specific keyword. lastly, it analyze type and contents of house in rural area from selected article. This process make up the rural housing for effective utilization. The result showed that the type of economic activity and residents information directly show the character of the members who located in the new homes after retuning to farming. The polarization of structure was clearly visible by the building time. And, propensity to western-style of major components was very high such as shape and form of housing. However, it was found to prefer to reflect traditional aesthetics in the components of the housing partially. Therefore, more research is needed to reflect of the results of a survey. Also, analyzing the characteristic of rural house's element and suggesting ways to take advantage in order to present suitable element of modern rural house.

Fashion industry constantly produces and consumes, which leads to huge waste piles of perfectly usable textiles in landfills, as well as other negative effects of an exploitative and excessively rapid fashion process. Pollution created by making and dyeing clothes has pitted fashion industry and environmentalists against each other. In this context, upcycling is seen as an optimal way to solve the growing problem of waste in fashion industry. The first purpose of the study was to analyze the relationships between upcycling fashion products' perceived value, pro-environmental beliefs, attitudes, electronic word of mouth (eWOM) intention, and purchase intention. The second purpose is to verify the difference of perceived consumption value among the consumers' awareness level and purchase experience. A total of 258 valid responses obtained from a group of 20-30-year-old participants were collected through an online survey. SPSS 23.0 and Amos 18.0 programs were used for data analysis. The results of the present study suggest that there are significant effects of upcycling fashion products' perceived value on pro-environmental belief; furthermore, pro-environmental belief was found to positively influence attitude, eWOM intention, and purchase intention. In addition, there are differences of perceived consumption value among the consumers' awareness level and purchase experience. Taken together, the results of this study provide researchers and practitioners with a deeper understanding of consumers' values, beliefs, attitudes, and behavioral intentions towards upcycling fashion products.

Background: Large rivers are ecological treasures with high human value, but most have experienced decades of degradation from industrial and municipal sewage, row-crop agricultural practices, and hydrologic alteration. We reviewed published analyses of long-term fish diversity publications from three intensively managed large river ecosystems to demonstrate the conservation potential of large river ecosystems. Results: We show how the incorporation of recent advances in river concepts will allow a better understanding of river ecosystem functioning and conservation. Lastly, we focus on the Wabash River ecosystem based on high conservation value and provide a list of actions to maintain and support the ecosystem. In the Wabash River, there were originally 66 species of freshwater mussels, but now only 30 species with reproducing populations remain. Although there were multiple stressors over the last century, the largest change in Wabash River fish biodiversity was associated with rapid increases in municipal nutrient loading and invasive bigheaded carps. Conclusions: Like similarly neglected large river systems worldwide, the Wabash River has a surprising amount of ecological resilience and recovery. For instance, of the 151 native fish species found in the 1800s, only three species have experienced local extinctions, making the modern assemblage more intact than many comparable rivers in the Mississippi River basin. However, not all the changes are positive or support the idea of recovery. Primary production underpins the productivity of these ecosystems, and the Wabash River phytoplankton assemblages shifted from high-quality green algae in the 1970s to lower less nutritional blue-green algae as nutrient and invasive species have recently increased. Our recommendations for the Wabash River and other altered rivers include the restoration of natural hydrology for the mainstem and tributaries, nutrient reductions, mechanisms to restore historical hydrologic patterns, additional sediment controls, and improved local hydraulics.
