This study is carried out in order to propose a drought risk assessment methodology. This methodology is required to deal with practical questions that a variety of stakeholder often raise in the course of discussions on mitigation measures. With a focus on the socioeconomic aspect of drought, more particularly, residents' hardship from water scarcity, it suggests basic concepts and a system of methods in order to assess hazard, exposure, vulnerability and risk. The case study shows a considerable possibility of the methodology in evaluating potential levels of damages in a certain area, in identifying the boundary of districts where risk is disproportionately concentrated, and also in understanding the underlying risk factors of those districts. The authors think that the proposed methodology is able to offer risk information in terms of socioeconomic damages, and therefore contribute to reducing information gaps that policy-makers are currently encountered with.

본 논문에서는 기후변화가 수자원의 이수측면에서 어떠한 영향을 미치는지에 대하여 검토하고자 한강유역에 대한 물수지 변화를 분석하였다. 이를 위하여, 우선 RegCM3 RCM ($27{\times}27\;km$)의 A2 기후변화 시나리오를 이용하여 모의된 70년의 일강우량을 강우유출모형인 SLURP 모형의 입력자료로 활용하여 70년의 일유출량을 모의하였다. 다음으로 수자원평가계획모형인 K-WEAP 모형을 이용하여 한강유역의 월별 물수지 분석을 실시하였다. 하지만, 미래의 물수요와 기후변화에 의한 유출량을 예측하는 데는 많은 불확실성을 내포하기 때문에 3개의 물수요와 50개의 유출 시나리오를 가정하여 검토하였다. 여기에서, 3개의 물수요 시나리오는 예상되는 물수요에 따라 저수요, 기준수요, 고수요로 구분되며, 50개의 유출 시나리오는 70년 기간 동안 50 set씩 모의된 유출량계열을 의미한다. 따라서 3개의 기후변화 시나리오와 50개의 유출량 시나리오를 조합하여 150 Set의 입력자료를 구성하고 K-WEAP 모형을 이용하여 분석하였다. 검토 결과 미래에 한강유역의 물부족량은 장기적으로 증가하는 것으로 예상되었다. 그리고 한강유역의 소유역별 물부족량을 검토한 결과 특정 소유역에서 물부족이 가중되고 장기적으로 한강유역 전체로 물부족이 예상되는 소유역이 증가함을 확인할 수 있었다.

The study was conducted at village level in Pabna milkshed areas of Bangladesh to asses the existing feed and fodder sources of cattle. The results showed that the overall number of cattle per farm family was 7.17 and chicken represents highest number (15.57) per farm family in this area. The results also indicated that during monsoon season the bathan is planted with Vigna mungo and Lathyrus sativus and average grazing hours per day varied from 1.1 in October to 5.6 in February. In Summer, they were offered naturally grown Cynodon dactylon with supplementary feeding of rice straw. The study further showed that the highest (65.7%) feed scarcity was found during mid April to mid May followed by mid June. The cultivation of Vigna mungo was highest (76.71%) compared to Lathyrus sativus by the farmers in the bathan areas. The major constraint to cattle production is the scarcity of quality feed during mid October to mid November.

This paper sought to provide information regarding the water resources in the Philippines, focusing on the issues of water quality, status of water use and water scarcity, and other threats to water availability. Although the country has sufficient amount of water resources, it was found out that water availability is still threatened by some major water resources problems: increasing water demand due to drastic growth in population, water resources pollution, droughts and flooding and weak institutional framework to address these problems. Water quality problems include increasing groundwater and surface water pollution. Moreover, drought and flooding have also increased damages in recent years due to deteriorating watersheds and high economic and population growth. In relation to these, the government enacted national laws to define and deal with water control and quality management. The objective of this research was to present and evaluate current conditions and issues on Philippine water resources.

The purpose of this paper is to perform empirical studies on the impact of pollution intensity on international competitiveness using 1993 and 1998 data, and to estimate the change in environmental regulation level faced by the firms during 1993~1998. Collecting relevant data and providing them for further studies in the area are another purposes of the paper. The first method is the regression of various indices of international competitiveness on factor costs, such as labor, capital, R&D and pollution abatement costs. Goal of the regression analysis is to estimate the scarcity and comparative advantage effect of each production factor, especially environmental resource. Regression results show that those industries which employ more environmental resource have higher comparative advantage in both years, which implies that Korean firms are endowed with abundant environmental resource compared to other countries. The second method is to compute the relative scarcity indices(HOVL indices) of production factors, proposed by Leamer based on Vanek's generalized Hecksher-Ohlin Theorem. This method estimates the relative scarcity of production factors by computing factor costs embodied in import and export of commodities. This method shows similar results as the regression method; i.e., trade pattern of production factors implies that the manufacturing sector in Korea is endowed with abundant environmental resource compared to other countries. Considering population density, water resource endowment, intensity of economic activity per unit area and current air and water pollution levels, it is evident that Korea is never endowed with abundant environmental resource compared to other countries. Then the abundance of environmental resource revealed by the trade patterns of commodities and production factors implies that Korea's environmental regulation level is excessively generous compared to environmental capacity, and that this increased the environmental resource endowment supplied to firms and thus distorted the inter-industry comparative advantages. Both regression and HOVL methods, on the other hand, show that overall environmental regulation level faced by the firms has been strengthened during 1993~1998.

This study sought to understand the clothing consumption values of male consumers and analyze the attributes of online fashion multi-brand stores. The study examined the effect of clothing consumption values of male consumers on the perceived attributes of online fashion multi-brand stores and use intention. The study also aimed to investigate whether online information search moderated the relationship between the perceived attributes of online fashion multi-brand stores and use intention. An online survey of male consumers in their 20s and 30s was conducted, and a total of 338 responses were analyzed. The SPSS 24.0 program was used to perform frequency analysis, factor analysis, reliability analysis, regression analysis, and stepwise-regression analysis. The results are as follows. First, fashionableness out of the four attributes of online fashion multi-brand stores (fashionableness, entertainment, variety, and scarcity) influenced the practical and conspicuous values of clothing consumption values. Entertainment had a significant effect on all clothing consumption values. Variety had a significant impact on practical and conspicuous values and the scarcity factor influenced epistemic and conspicuous values. Second, while entertainment, variety, and scarcity influenced sharing intention, fashion, entertainment, and variety influenced purchase intention. Third, online information search moderated the relationship between the perceived attributes of online fashion multi-brand stores and sharing intention but not purchase intention.

The concept of virtual water has been largely applied in the study of regional, national, and global water flows with particular emphasis on water scarcity. Despite water traditionally being managed locally, certain global forces influence the local water resource scarcity/availability and hence virtual water exchanges worldwide. It is therefore of necessity that the significant forces be examined to understand the relationship between available water in a region and the variability and trends in environmental, social, and economic factors that are of utmost importance in the formulation of water resources management policies. This study therefore reviewed recent literature from 2003 - 2019 to determine the significant indicators of virtual water trade at different spatiotemporal levels. The study examined and compared the major approaches to virtual water trade flows accounting, and also identified and discussed policy implications and future research options concerning the analysis of virtual water trade. Available information has shown that virtual water trade is significantly influenced by economic (GDP, Demand-Supply of goods and services), geographical (Distance), institutional (population) and environmental (water availability, arable land, precipitation) factors. Reports further show that the selection of a given approach for virtual water trade flows accounting will depend on the scope of the study, the available datasets, and other research preferences. Accordingly, this study suggests that the adoption of multidisciplinary approaches to virtual water trade, taking into consideration the spatial and temporal variations in water resources availability and the complexity of environmental and socioeconomic factors will be pivotal for establishing the basis for the conservation of water resources worldwide.

공유 경제의 대표적인 사례 중 하나의 카 쉐어링 서비스는 차량을 공유하여 사용자가 원하는 시간, 장소에서 원하는 만큼 공유하여 사용할 수 있는 서비스를 제공하고 있다. 본 연구에서는 카 쉐어링 서비스의 시스템이 제공하는 기반적 특성인 희소성과, 시스템 품질, 서비스 품질이 사용자의 평가 요소에 영향을 줄 것이라 가정하고 사용자의 평가를 통하여 사용자의 순 편익을 확인하고자 하였다. 분석결과 희소성의 쿠폰과 시간제한은 사용자 평가 요소인 인지된 사회적 지지와 앱 신뢰에 영향을 주었으나 제한 수량은 영향을 주지 않아 카 쉐어링 서비스에서 수량에 대한 제한은 관련 없는 것으로 나타났다. 시스템 품질의 대부분의 변수들이 인지된 사회적 지지와 앱 신뢰에 영향을 주었다. 사용자 평가는 사용자 만족과 추천의도에 영향을 주었다. 사용자가 얻을 수 있는 순 편익으로써 만족감과 조직적 측면에서의 간접적 성과인 추천 의도가 채택되어 순 편익 변수의 역할을 하였다. 공유경제와 관련된 연구는 주로 탐색적 연구에서 국한하는 점으로 비추어 볼 때 본고에서 언급하고 있는 비즈니스 성공 모델의 적용과 사회적 변수 적용 등 실증적으로 분석했다는 점에서 본 연구의 의의가 있다.
