가뭄은 자연적 현상이지만, 지역의 물리적 및 사회적 요소와 결합되어 피해가 발생한다. 특히, 각종 용수 공급 및 수요과 연관되어 사회 경제적으로 큰 피해를 야기시킨다. 비슷한 심도의 기상학적 가뭄에도 지역의 특성과 용수공급체계에 따라 실제로 발생하는 가뭄 피해는 다르다. 본 연구에서는 지역의 사회·경제적 인자와 용수공급체계를 고려하여 가뭄 위험도를 평가하였다. 노출성은 용수공급 과부족량을 나타내는 결합가뭄관리지수(JDMI)를 등급화하여 평가하였다. 취약성은 가뭄에 영향을 받는 10개의 사회·경제적 인자에 엔트로피, PCA 및 GMM를 적용하여 가중평균하여 평가하였다. 대응능력은 지역의 용수능력을 나타내는 인자들을 베이지안 네트워크에 적용하여 평가하였다. 위험도는 노출성, 취약성 및 대응능력을 통합하여 결정하였다. 용수공급 실패 사상의 발생 가능성을 의미하는 가뭄 노출성을 평가한 결과, 괴산군이 0.81로 가장 높게 나타났다. 가뭄 취약성의 경우, 대전광역시가 0.61로 매우 취약한 것으로 나타났다. 지역의 용수공급체계가 고려된 가뭄 대응능력을 평가한 결과, 세종시가 가뭄 대응능력이 가장 낮은 것으로 나타났다. 마지막으로 위험도를 평가한 결과, 청주시가 가장 높게 나타났다. 이러한 결과를 통해 가뭄에 대한 위험 및 취약 원인을 파악하였으며, 향후 지역의 특성을 고려한 가뭄 피해 저감 정책 마련이 가능하다.

This paper attempts to provide a way to improvement in trade & commerce between Korea and Russia, analyzing the influence of the circumstances of the Russian economy on economic relations between the two countries. The study briefly reviews the current situation of the Russian economy, and tries to examine the strong points to be considered as leverage for cooperation and the weak points to be overcome. Previous studies have determined that the Russian economy has unlimited potential for growth, because it is endowed with abundant resources, and has a government willing to reform for the opening of the economy, as well as high-quality labor. However, the economic structure is vulnerable to impact of the worldwide financial crisis. It is not possible to overlook its institutional fragility and vulnerability such as a corrupt bureaucracy or a relatively large black market. These undesirable factors may not only undermine the basis of Russia economy but also a hindrance to economic cooperation by increasing economic uncertainty. This paper attempts to analyze comprehensively the socio-economic factors that influence the open-economy of Russia, and to illustrate strategies for improvement in trade and commerce through the viewpoint of Korean firms that are already in business or are trying to enter in the near future. Some measures to improve their economic cooperation are suggested at the end.

Purpose: To determine the socio-economic impact of gluten free diet (GFD) on Saudi children and their families Methods: A cross-sectional study was conducted in which an online questionnaire was sent to all families registered in the Saudi celiac patients support group. We included only children (age 18 years of age and younger) with biopsy-confirmed celiac disease (CD). Results: A total of 113 children were included in the final analysis, the median age was 9.9 years; 62.8% were females. One hundred (88.5%) of the participating families reported that GFD food was not easily available in their areas, 17% of them reported that it was not available at all in their area. One hundred and six (93.8%) reported that the price of GFD food was very expensive and 70 (61.9%) families that the diet was heavily affecting their family budget. Significant social difficulties were reported among the participating families and their children including interference with the child's interaction with other children (49.6%), the families' ability to attend social gatherings (60.2%), the families' ability to eat in restaurants (73.5%), and the families' ability to travel (58.4%). Conclusion: There is significant negative socio-economic impact of GFD on children with CD & their families. Health care providers should be aware of these psycho-social difficulties and be well trained to provide a proper education and psychological support for these patients and their families.

Climate of Mongolia is a driven force on natural conditions as well as socio-economic development of the country. Due to the precariousness of climate conditions and traditional economic structure, natural disasters, specially disasters of meteorological and hydrological origin, have substantial effect upon the natural resources and socio-economic sectors of Mongolia. Mongolia's climate is characterized by high variability of weather parameters, and high frequency and magnitude of extreme climate and weather events. During the last few decades, climate of the country is changing significantly under the global warning. The annual mean air temperature for the whole territory of the country has increased by $1.56^{\circ}C$ during the last 60 years,. The winter temperature has increased by $1.56^{\circ}C$. These changes in temperature are spatially variable: winter warming is more pronounced in the high mountains and wide valleys between the mountains, and less so in the steppe and Gobi regions. There is a slight trend of increased precipitation during the last 60 years. The average precipitation rate is increased during 1940-1998 by 6%. This trend is not seasonally consistent: while summer precipitation increased by 11 %, spring precipitation decreased by 17. The climate change studies in Mongolia show that climate change will have a significant impact on natural resources such as water resources, natural rangeland, land use, snow cover, permafrost as well as major economic activities of arable farming, livestock, and society (i.e. human health, living standards, etc.) of Mongolia. Therefore, in new century, sustainable development of the country is defined by mitigating and adaptation policies of climate change. The objective of the presentation is to contribute one's idea in the how to reflect the changes in climate system and weather extreme events in the country's sustainable development concept.

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.

In order to effectively prepare for damage caused by weather events, it is important to proactively identify the possible impacts of weather phenomena on the domestic society and economy. Text mining and Network analysis are used in this paper to build a database of damage types and levels caused by heat wave. We collect news articles about heat wave from the SBS news website and determine the primary and secondary effects of that through network analysis. In addition to that, based on the frequency with which each impact keyword is mentioned, we estimate how much influence each factor has. As a result, the types of impacts caused by heat wave are efficiently derived. Among these types of impacts, we find that people in South Korea are mainly interested in algae and heat-related illness. Since this technique of analysis can be applied not only to news articles but also to social media contents, such as Twitter and Facebook, it is expected to be used as a useful tool for building weather impact databases.

The study aims to identify residents' perceptions of tourism impacts according to the demographic characteristics. The analysis was based on 366 questionnaires given to residents of six rural communities in rural Korea. A series of data analysis such as factor analysis, t-test, and ANOVA was conducted to investigate the residents perceptions of tourism impacts. Results showed that whereas younger, less educated and poor could perceive a negative impacts. older, educated and richer were more likely to perceive a positive impacts of economic, social and environmental spheres. Especially male was more likely to perceive a positive socio-cultural impacts, whereas female was perceive a negative impacts. The results suggest that it is important for policy makers and community leaders to consider social-cultural and economic impact when decision making on development planning.

An integrated waste management approach for irradiated graphite was developed during the European Commission project 'Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste'. This included the identification of potential options for the management of irradiated graphite, taking account of storage, retrieval, treatment and disposal methods. This paper describes how these options can be assessed using multi-criteria decision analysis (MCDA) for a case study relating to a generic power reactor. Criteria have been defined to account for safety, environmental, economic and socio-political factors, including radiological impact, resource usage, economic costs and risks. The impact of each option against each criterion has been assessed using data from the project and the wider literature. A linear additive approach has been used to convert the calculated impacts to scores. To account for the relative importance of the criteria, example weightings were allocated. This application has shown that MCDA approaches can be used to support complex decisions regarding irradiated graphite management, accounting for a wide range of criteria. Use of this approach by individual countries or organisations will need to account for the specific options, scores, weightings and constraints that apply, based on their national strategies, regulatory requirements and public acceptability.
