The purpose of this paper is to clarify the prospects and problems in the study of geography related to the concept of commodity, transport, and supply chains. The geography studies related to commodity chains are expanded to each field of industry focusing on the subjects and economic difference which lead the commodity chain in core and periphery regions. These vertical connection are studied with the political economy approach that gives attention to geographical pattern of agricultural products and foods. But in viewpoint of commodity circuit and commodity network, the culture or subjects of micro regions and interaction are also studied. The contents of these study are to clarify the importance of cultural turn and local. And the study of chain standpoint appears that the series of transport process by transportation modes can be understood by transport chains and the physical distribution process of sea freight is to be grasped by supply chains.

국가간 지역간 물의 이동을 개념화하여 물 부족 현상을 정치경제학적 관점에서 접근하려는 가상수(virtual water) 연구가 국제적으로 진행되고 있다. 가상수를 양적 측면에서 산정하여 정확한 물 수지를 파악하면 수자원에 대한 국가의 계획과 전략 수립에 매우 유리한 여건이 조성된다. 우리나라의 국가계획인 수자원장기종합계획은 국가 간의 물 이동을 고려하지 않고 국내에서 발생하는 용수의 수요와 공급 측면만을 산정하고 있다. 그러나 현재에도 국내에서 소비하는 농산물과 축산물의 상당량은 수입에 의존하고 있으며, 향후 국제교역과 FTA의 확대 등으로 그 의존도는 더욱 증대될 것으로 추산된다. 따라서 국가 간 물 이동에 대한 양적 규모를 파악하여 국가전략을 수립하는 기초자료로 활용하기 위한 연구가 필요하다. 이에 본 연구에서는 산업연관분석법을 활용하여 국내 산업별(제조업, 서비스업) 가상수를 산정하여 국가 수자원계획 수립에 필요한 기초자료로서 제공하고자 한다. 산업연관분석(Inter-industry analysis)은 산업연관표를 바탕으로 산업 간의 상호 연관관계를 수량적으로 파악하는 방법이다. 이를 가상수 산정에 활용하여 직접수와 간접수를 포함한 물의 전체 사용량을 산정할 수 있다. 본 연구에서는 각 산업의 용수량을 총 생산량으로 나누어 물 강도($m^3$/원)를 계산하고, 생산유발계수와 최종수요를 곱하는 방식으로 산업별 가상수량을 산정하였다. 산업별 가상수 산정 결과는 경제총조사의 용수비와 산업연관표의 생산유발계수를 적용하였으며, 제2차 산업인 제조업 분야의 연간 가상수량은 60.4억 $m^3$, 제3차 산업인 서비스 분야의 가상수량은 연간 43.1억 $m^3$으로 분석하였다. 또한 향후 10년의 OECD 기술수준 제품군별 무역수지 전망을 고려한 결과, 기술수준 중 및 고 기술제품의 가상수 수출량이 2020년에는 2010년에 비해 약 3배 증가하는 것으로 산정하였다. 이와 같은 방법으로 산정된 산업별 가상수는 각 산업의 물 사용량을 추정하고 산업 전반의 수자원 활용도를 파악하는데 이용 가능하다. 더불어 국제 환경 및 기후변화가 반영된 가상수 시나리오 연구를 통해 장래 용수 수요변화예측 등 효과적인 물 관리 정책 수립에 기여할 수 있다.

This study analyzed the competitiveness of major export industries following the FTA between Korea and five Central American countries. Findings revealed that Korea mainly exports industrial products such as ships, automobiles and parts, steel, and electronic devices, and it imports raw materials and agricultural products such as coffee and copper, indicating a complementary trade structure. Similarly, the trade specialization index analysis revealed that Korea specialized in exporting industrial products such as ships, automobiles, steel, and machinery, and in importing primary products such as copper and coffee. Products such as ships, steel, and machinery, which are major export items to Central America, are expected to further strengthen their competitiveness due to tariff cuts. In addition, it is expected that the demand for medicines and medical supplies could increase in future due to the COVID-19 pandemic. This study attempted to present implications for establishing export strategies by analyzing the competitiveness of Korea's major export industries in the Central American market, in accordance with the Korean-Central American FTA. These findings could be used as basic data for future entry into South America as a bridgehead in the Central American market.

The environments in current farming and fishing communities have been exacerbated by the shortage of personnel caused by aging, the deficiency of equipment, and the decrease in produce prices. To help solve these issues, this study examined the history, such as inspections, failures, and repairs, by constructing a database for underground water wells, pumping stations, and irrigation, which are critical for management among agriculture production infrastructures. In particular, in the case of underground water wells, their optimal locations were determined using spatial information, such as a geological map of water resources, a water vein map, and underwater depth, because indiscreet installations and an absence of spatial information resulted in economic losses and environmental pollution. Therefore, this study could efficiently manage many facilities scattered in rural areas by developing a system. An analysis of the status of 14 underground water wells using spatial information showed that the location information at six points was specified incorrectly. On the other hand, a site investigation showed that the water vein map analysis at one point was inaccurate.

This study aimed to investigate the use of environmentally friendly agricultural products (EFAPs) in Chungcheongbuk-do and the perception and satisfaction of school dietitians with EFAPs. The study survey was conducted from April to Jun 2018. Among 195 dietitians, 54.4% were nutrition teachers and 51.3% were working in elementary schools. Of the participants, 65% answered that the percentage of EFAPS in the total food cost was 10~30%. The most used EFAP food group was grains (64.6%), followed by vegetables (26.2%). The main reasons for using EFAPs were subsidies for EFAPs from local governments (85.1%) and students' health (52.3%). The average daily subsidy for EFAPs from the local governments was 201~500 won at 45.1%, and 200 won or less at 34.9%, which was based on one meal per student. In questions on satisfaction with using EFAPs, satisfaction with safety (3.93 out of 5 points) scored the highest, followed by nutrition (3.74), freshness (3.70), appearance (3.32), diversity (2.85), and price (2.78). Therefore, to expand the use of EFAPs in school food service, it is necessary to expand the provision of subsidies and increase EFAP production diversification.

농업 분야에서 미생물은 영양분 가용화, 유기물 분해 등 토양 영양분 공급에 중요한 역할을 하며, 토양 건강성 증진, 식량 안보 및 식품 건강 면에서 많은 활용 가능성을 지니고 있다. 최근 유역 환경 건강성, 생물 다양성 보존, 효율적인 고품질 농산물 생산에 대한 관심이 커져, 지속 가능한 농업 중 하나인 유기농업과 관행농업 토양의 이화학적 및 생물학적 특성에 관한 비교 연구가 진행되고 있다. 미생물은 지속 가능한 농업 발전의 중요한 요소 중 하나로써, 미생물 다양성이 풍부할수록 토양 비옥도, 작물 성장 면에서 긍정적인 영향을 미친다고 알려져 있다. 본 연구는 이에 대한 기초 데이터를 제공하기 위해 논 경작지를 대상으로 유기 및 관행농업 토양의 미생물 군집조성과 Alpha diversity analysis(Chao1, Shannon, Simpson index)을 통해 비교하였다. 경기도 양평군에서 유기 및 관행 논 지역을 각각 1지점씩 선정하였으며, 8월부터 11월까지 총 4회 현장 조사를 진행하였다. 미생물 분석은 차세대염기서열분석을 실시하였으며, bacteria는 16S rRNA V3-4 영역, fungi는 ITS 3-4 영역을 sequencing 하였다. 미생물 군집조성은 문수준에서는 큰 차이가 없었으나, 속수준에서는 fungi 군집조성에 차이를 보였다. 예로 Ustilaginoidea 속은 관행 논 토양에서만 발견되었으며, 벼 이삭누룩병을 일으키는 병원균으로 과도한 질소 비료 시비가 원인으로 추정된다. 종 다양성은 bacteria diversity의 경우 관행 논 토양에서 높게 측정되는 반면, fungi diversity의 경우 유기 논 토양에서 높게 측정되었다. 결론적으로 체계적인 시비 관리 통해 미생물 군집은 조절될 수 있으며, 관행농업은 적절한 시비를 통해 토양 건강성 및 식품 건강성 면에서 유기농업과 비슷한 효과를 보여줄 가능성이 있다고 판단된다.
