  • 최근 무인항공기를 지칭하는 드론 관련 산업이 미래를 이끌 신산업으로 부상하고 있다. 드론은 20세기 초에 군사용으로 개발되어 정찰 감시 및 폭격과 같은 군사임무를 수행하여 왔으나 최근 들어 독일 DHL, 아마존, 구글 등과 같은 다국적 기업들이 상업적 용도로 활용을 선언하며 연구 개발에 뛰어 들면서 그 시장이 예상보다 빨리 커지고 있다. 미국 틸 그룹의 보고서에 의하면 2013년 세계 드론 시장의 규모는 66억 달러였고 그 중 군사용이 90% 이상을 차지하고 있으나 향후 민수용 시장 비율이 상당히 커질 것으로 예상된다. 2022년에는 114억 달러 규모로 커질 것으로 예상하고 있다. 현재 민수용으로 사진 촬영용 소형 드론으로부터 정밀농업, 인프라 관리, 택배 및 화물 수송 등으로 운용 범위를 확대하고 있다. 국내 드론 산업은 군수 위주로 시작되어 세계 7위권의 기술력을 확보한 것으로 평가되고 있다. 무인기 분야의 연구개발은 국방과학연구소와 한국항공우주연구원 등 정부출연연구소가 주도하는 가운데, 한국항공우주산업, 대한 항공이 주로 체계종합(System Integrator) 및 비행체 개발을 담당하고 LIG넥스원, 삼성탈레스, 삼성테크윈 등의 대기업을 포함한 중소업체들이 부체계 기술을 개발하고 있다. 최근 소형 드론을 중심으로 시장형성이 가시화되는 민수 시장에서는 가격, 기술 경쟁력의 열위에 있어, 국내 산업 경쟁력 확보와 미래 시장을 선도할 핵심 제품 개발이 시급한 실정이다. 또한 무인기의 비행체 국산화는 상당한 수준으로 진행되었으나, 광학(EO) 적외선(IR) 카메라 등 핵심 부가가치를 구성하는 탑재 임무장비의 경우 원천기술의 부족으로 해외에 의존하고 있다.

  • Central Asia (Uzbekistan, Kazakhstan, Kyrgyzstan) is a hot and arid continental climate, with most areas (68%) consisting of barren vegetation, desert, and meadows. The main agricultural areas for crop production include irrigated farmland, non-irrigated farmland, grassland, prairie and mountain. We are experiencing climate change with recent climate variability increasing. Agriculture is one of major economic sectors and provides a means of livings for the rural population of Central Asia, especially the poor. In the past two decades, Central Asia has experienced a high population growth rate, with Kazakhstan at 16.8%, Uzbekistan at 34.5% and Kyrgyzstan at 28.4%. As a major industry, Kazakhstan has the largest share of exports of agricultural products followed by petroleum, mineral resources, steel, and chemicals. Uzbekistan is the fifth largest cotton exporter as well as the sixth largest cotton producer in the world. Kyrgyzstan exports ores, stones, cultured pearls, and minerals. These three countries are rich in mineral resources, agricultural products, and energy resources. However, not only do they have difficulties in economic development due to the weakness of logistics and industrial infrastructure, but they also have imperceptible cooperation and investment among countries due to insufficient research and development. Through this study, we will investigate national outlook, economic indicators, major agricultural products, import and export status, and agricultural technology cooperation status, and study how Korean agricultural industry advances into these countries through SWOT analysis. Through this, we hope to contribute to the basic data of Central Asian studies and cooperation and investment in agriculture in each country. In addition, in order to increase cooperative exchange and investment in these countries, we will prepare a Central Asia logistics hub for the rapidly changing interKorean railroad era.

  • Paris Agreement signed in January 2015 is a new rule that will replace the existing Kyoto Protocol. The new agreement needs new demands and challenges to minimize carbon emissions. Especially, even though agricultural sector occupies only 1.8% in the national energy consumption, the portion of the energy being occupied in agricultural production costs very high. Although renewable energy and energy-saving facilities is being developed and disseminated for replacing fossil fuel energy and saving energy, the installation-rate is not enough high. Thus, this paper developed Korean-style smart farm system, and carried out the experiment to show the performance of energy savings through analyzing proper environment in domestic situation.

  • 고품질 농산물을 대량 생산하기 위한 가장 중요한 것은 적절한 관개관리이다. 생육시기별 작물 재배에 있어서 꼭 필요한 만큼의 물을 필요한 때에 준다면, 농업용수를 절약할 수 있을 뿐만 아니라, 작물의 한발 및 습해에 따른 피해를 최소화 할 수 있을 것이다. 기존의 토양 및 증발산량 기반의 자동 물관리 기술의 경우 직접적으로 작물의 상태변화를 실시간으로 확인할 수 없으며, 측정오차가 크고 작물수량이 많을 경우 측정시간 및 소요비용이 크다는 단점이 있다. 이를 극복하기 위해 최근 작물의 수분 스트레스를 비파괴적으로 측정하여 관개계획에 활용하는 연구가 해외에서 활발히 이루어지고 있다. 본 연구에서는 열영상 기술을 활용한 적정 관개계획 수립과 관련된 국내외 연구 사례를 소개하고, 오이를 대상으로 토양수분함량 변화에 따른 엽온 변화를 측정하고, 실시간으로 작물의 수분스트레스 여부를 분석하기 위한 예비실험을 실시하였다. 엽온 측정을 위해 적외선 센서(CT-300-232, DiWell, Korea)를 사용하였으며, 관개조건에 따른 엽온 및 FDR센서를 이용하여 토양수분변화를 모니터링 하였다. 세 가지 토양수분조건, 즉 200% $ET_c$(과다관개), 100% $ET_c$(적정관개), 30% $ET_c$(과소관개),을 시험구에 조성하고, 각각의 처리구에 따른 엽온변화를 측정하였다. 동일한 대기온도하에서 엽온의 변화를 살펴본 결과, 과소관개한 시험구에서의 엽온변화 폭이 가장 컸으며, 적정관개의 엽온 변화폭이 가장 작게 나타났다. 이는 물관리 조건에 따라 많이 줘도, 적게 줘도 스트레스 요인으로 작용함을 확인할 수 있었다. 향후 연구에서는 실시간 엽온자료와 더불어 기상자료를 활용하여 작물 수분스트레스 지수(Crop Water Stress Index, CWSI)을 산정하고, 이를 관개시설 운영 및 제어에 활용하기 위한 모듈 개발을 수행할 계획이다.

  • Recently concerns have been raised due to the unbalanced supply of crops: the price of crops has been unstable and at one point the price went up so high that the word Agflation(agriculture+ inflation) was coined. Korea, in particular, is a small-sized country and needs to secure the stable supply of crops by investing in the produce importation at a national level. Investment in foreign produce importation is becoming more important as a measure for sufficient supply of crops, limited supply of domestic crops, weakened farming conditions worldwide, as well as recent changes in the use of crops due to the development of bio-fuels, influence of carbon emission on crops, the price increase in crops, and influx of foreign hot money. However, there are many problems with investing in foreign produce importation: lack of support from the government; lack of farming information and technology; difficulty in securing the capital; no immediate pay-off from the investment and insufficient management. Although foreign produce is originally more price-competitive than domestic produce, it loses its competiveness in the process of importation (due to high tariffs) and poor distribution system, which makes it difficult to sell in Korea. Therefore, investment in foreign produce importation is being questioned for feasibility; to make it possible, foreign produce must maintain the price-competitiveness. Especially, harvest of agricultural products depends on natural and geographical conditions of each country and those products have indigenous properties, so distribution system according to import and export of agricultural products should be treated more carefully than that of other industries. Distribution costs are differentiated into each item and include cost of sorting and wrapping, cost of wrapping materials, cost of domestic transport, cost of international transport and cost of clearing customs for import and export. So transporting and storing agricultural products generates considerable costs compared with other products. Also, due to upgrade of dietary life, needs for stability, taste and visible quality toward food including agricultural products are being raised and wrong way of storage causes decomposition of food and loss of freshness, making the storage more difficult than that in room temperature, so storage and transport in distribution of agricultural products needs specialty. In addition, because lack of specialty in distribution and circulation such as storage and wrapping does not solve limit factors in distance, the distribution and circulation has been limited to a form of import and export within short-distant region. Therefore, need for distribution out-sourcing which can satisfy specialty in managing distribution and circulation and it is needed to establish more effective distribution system. However, existing distribution system of agricultural products is exposed to various problems including problems in distribution channel, making distribution and strategy for distribution and those problems are as follows. First, in case of investment in overseas agricultural industry, stable supply of the products is difficult because areas of production are dispersed widely and influenced by outer factors due to including overseas distribution channels. Also, at the aspect of quality, standardization of products is difficult, distribution system is quite complicated and unreasonable due to long distribution channels according to international trade and financial and institutional support is not enough. Especially, there are quite a lot of ineffective factors including multi level distribution process, dramatic gap between production cost and customer's cost, lack of physical distribution facilities and difficulties in storage and transport due to lack of wrapping containers. Besides, because import and export of agricultural products has been manages under the company's own distribution according to transaction contract between manufacturers and exporting company, efficiency is low due to excessive investment in fixed costs and lack of specialty in dealing with agricultural products causes fall of value of products, showing the limit to lose price-competitiveness. Especially, because lack of specialty in distribution and circulation such as storage and wrapping does not solve limit factors in distance, the distribution and circulation has been limited to a form of import and export within short-distant region. Therefore, need for distribution out-sourcing which can satisfy specialty in managing distribution and circulation and it is needed to establish more effective distribution system. Second, among tangible and intangible services which promote the efficiency of the whole distribution, a function building distribution environment which includes distribution information, system for standard and inspection, distribution finance, system for diversification of risks, education and training, distribution administration and tax system is wanted. In general, such a function building distribution environment is difficult to be changed and supplement innovatively because its effect compared with investment does not appear immediately despite of its necessity. Especially, in case of distribution of agricultural products, as a function of collecting and distributing is performed individually through various channels, the importance of distribution information and standardization is getting more focus due to the problem of repetition of work and lack of specialty. Also, efficient management of distribution is quite difficult due to lack of professionals in distribution, so support to professional education is needed. Third, though effort to keep self-sufficiency ratio of staple food, rice is regarded as important at the government level, level of dependency on overseas of others crops is high. Therefore, plan for stable securing food resources aside from staple food is also necessary. Especially, governmental organizations of agricultural products distribution in Korea are production-centered and have unreasonable structure whose function at the aspect of distribution and consumption is quite insufficient. And development of new distribution channels which can deal with changes in distribution environment and they do not achieve actual results of strategy for distribution due to non-positive strategy for price distribution. That is, it implies the possibility that base for supply will become vulnerable because it does not mediate appropriate interests on total distribution channels such as manufacturers, wholesale dealers and vendors by emphasizing consumer protection excessively in the distribution of agricultural products. Therefore, this study examined fundamental concept and actual situation for our investment to overseas agriculture, drew necessities, considerations, problems, etc. of overseas agricultural investment and suggested improvements at the level of distribution for price competitiveness of agricultural products cultivated in overseas under five aspects; government's indirect support, distribution's modernization and distribution information function's strengthening, government's political support for distribution facility, transportation route, load and unloading works' improvement, price competitiveness' securing, professional manpower's cultivation by education and training, etc. Here are some suggestions for foreign produce importation. First, the government should conduct a survey on the current distribution channels and analyze the situation to establish a measure for long-term development plans. By providing each agricultural area with a guideline for planning appropriate production of crops, the government can help farmers be ready for importation, and prevent them from producing same crops all at the same time. Government can sign an MOU with the foreign government and promote the importation so that the development of agricultural resources can be stable and steady. Second, the government can establish a strategy for an effective distribution system by providing farmers and agriculture-related workers with the distribution information such as price, production, demand, market structure and location, feature of each crop, and etc. In order for such distribution system to become feasible, the government needs to reconstruct the current distribution system, designate a public organization for providing distribution information and set the criteria for level of produce quality, trade units, and package units. Third, the government should provide financial support and a policy to seek an efficient distribution channel for foreign produce to be delivered fresh: the government should expand distribution facilities (for selecting, packaging, storing, and processing) and transportation vehicles while modernizing old facilities. There should be another policy to improve the efficiency of unloading, and to lower the cost of distribution. Fourth, it is necessary to enact a new law covering exceptional cases for importing produce in order to maintain the price competitiveness; currently the high tariffs is keeping the imported produce from being distributed domestically. However, the new adjustment should be made carefully within the WTO regulations since it can create a problem from giving preferential tariffs. The government can also simplify the distribution channels in order to reduce the cost in the distribution process. Fifth, the government should educate distributors to raise the efficiency and to modernize the distribution system. It is necessary to develop human resources by educating people regarding the foreign agricultural environment, the produce quality, management skills, and by introducing some successful cases in advanced countries.

  • To create an environment for growing ginseng sprouts, we developed a solar module that partially transmits and disperses light. A G to G type light transmission and dispersion solar module was developed using glass with a mist pattern applied, and the light dispersion effect of the developed module was confirmed through illuminance measurement. The output of one module is approximately 260 W, and the configuration consists of 48 cells in series in 4 strings. The cultivation system where the developed module will be installed was developed in the form of a container, and three units of 2.6 kW (260 W x 10 EA). The inside of the cultivation system consists of a shading screen, air conditioner, ventilator, plastic pot, etc. to create an environment for cultivating sprout ginseng. As a result of actually planting sprout ginseng, it was confirmed through verification that the plants were grown without any problems.

  • 북한(北韓)의 경제개발전략(經濟開發戰略)의 제특징(諸特徵)은 저렴한 농산물가격(農産物價格)에 의한 농업부분(農業部分)에서의 잉여(剩餘), 저임금(低賃金)에 의한 도시노동자(都市勞動者)들로부터의 잉여(剩餘)를 가지고 경제발전(經濟發展)을 이룩하는 것이라 요약할 수 있다. 농민(農民), 도시노동자(都市勞動者) 양측(兩測)을 희생시키면서 유지되어 온 이러한 성장구조(成長構造)는 원래 같으면 저농산물가격(低農産物價格)${\rightarrow}$저임금(低賃金)${\rightarrow}$축적자금확대(蓄積資金擴大)${\rightarrow}$재투자(再投資)${\rightarrow}$생산량증가(生産量增加)${\rightarrow}$소비수준 (消費水準) 증가(增加)로 점진적으로 발전해야만 하는 것이다. 하지만 이러한 성장전략(成長戰略)은 처음부터 철저히 부정되어 왔다. 먼저 농촌부분(農村部分)부터 보면 농촌협동조합(農村協同組合)에서의 소유제도(所有制度), 분배제도(分配制度)의 문제(問題)로 인해 농민(農民)의 근로의욕(勤勞意欲)이 크게 상실되었고 그 결과(結果) 농업생산(農業生産)은 저하되었다. 한편 도시부분(都市部分)에서는 인민(人民)들의 저소비(低消費)의 결과(結果)로 축적된 자금(資金)이 군사부분(軍事部分)에 집중적으로 투자됨으로 인해 그 투자효과(投資效果)가 제 구실을 못하게 되었다. 뿐만 아니라 자급자족지향형(自給自足指向型)의 중공업화(重工業化)는 중공업(重工業)과 관련산업(關聯産業) 상호간(相互間)의 수요(需要)만을 충족시켜 왔다. 그 외에 기업(企業)이 국가(國家)의 지령(指令)에 의해서만 움직이는 국영기업관리체제(國營企業管理體制)의 비효율성(非效率性)도 지금의 북한경제(北韓經濟)를 침체(沈滯)의 늪에서 헤어나지 못하게 하는 주요(主要)한 요인(要因)으로 작용했다. 농업생산(農業生産)의 정체(停滯), 중공업(重工業)을 위한 중공업정책(重工業政策)이라고 하는 왜곡된 투자구조(投資構造), 기업관리체제(企業管理體制)의 비효율성(非效率性)은 북한(北韓)의 계획경제순환구조(計劃經濟循環構造)를 기본(基本)부터 뒤흔들기 시작하면서, 급기야 1980년대 후반부터는 순환구조(循環構造) 그 자체(自體)를 마비시키는 사태(事態)로까지 발전했다. 순환구조(循環構造)의 마비(痲痺)라고 하는 심각한 경제난(經濟難)을 타개하기 위해 북한(北韓)은 나진(羅津) 선봉(先鋒) 자유경제무역지대(自由經濟貿易地帶)를 설치(設置)하고 새로운 자금축적원(資金蓄積源)으로서 외국인직접투자(外國人直接投資)를 유치하는 개방정책(開放政策)을 추진하여 왔다. 하지만 북한(北韓)의 경제(經濟) 순환구조(循環構造)의 마비(痲痺)를 풀 수 있는 근본적(根本的)인 해법(解法)은 어디까지나 그 발단(發端)인 농촌(農村)의 경제체제개혁(經濟體制改革), 농(農) 경공업(輕工業)을 위한 중공업(重工業), 국영기업(國營企業)의 개혁(改革) 등을 과감히 실시하는 것이다. 왜냐하면 해외직접투자(海外直接投資)라는 새로운 자금축적원(資金蓄積源)은 어디까지나 지금의 악순환구조(惡循環構造)를 임시적(臨時的)으로 정지시켜 주는 보완적(補完的)인 조치(措置)에 불과하기 때문이다.

  • The purpose of this study is to review research trends and issues of economic geography in Korea for the last fifty years by sub-fields of agricultural geography, industrial geography, commercial and service geography, and transportation geography. Research in Korean economic geography has progressed significantly in terms of the scope and the number of papers published during the last a half a century. Agricultural geography was a leading field of economic geography in Korea before mid-1970s. Since the mid-1970s, however, agricultural geography has turned over the leading role in economic geography to industrial geography. Classification and structure of agricultural region has been the most popular research theme in Korea, even though diverse topics has been dealt in the research of agricultulal geography in Korea during the last fifty years. In recent years, emphasis is given to study on the dynamics of agricultural region and regional differentiation of part-time farming. It is suggested that the future issues of research in agricultural geography in Korea are agricultural restructuring and changes in agricultural space under the WTO system, changes in rural area and agricultural region with the progress of informatization, changes in agricultural structures and rural society by the increase of part-time farming, governments agricultulal policy and its impacts, competitive advantages of Korean agricultulal products, and environmental impacts of agricultural restructuring. Research in industrial geography has remarkably progressed since the 1980s. Locational changes, regional industrial structure and formation of industrial region were the major topics of interest in the research of industrial geography in Korea before 1980. Since the early 1980s, in addition to the topics which were interested in before 1980, changes of industrial organization and industrial location, changes of production systems and industrial space development of high technology industries and science parks, industrial restructuring and regional economy, foreign direct investments, industrial linkages and industrial districts, and industrial policy and regional development have been the major research themes of industrial geography in Korea. Considerable number of papers has been published both in Korean journals and in foreign journals during this period. Considering global changes in the organization of industrial space, future research should be more focused on firms strategy for regaining competitive advantages, local and global perspectives of industry, industry and environmental changes, in addition to the topics which have been dealt in recent years. Research in commercial and service geography and transportation geography was negligible in Korea before the late 1970s. These two sub-fields in economic geography have begun to develop since 1980s. Periodic markets, structure of commercial area, and distribution of products were the major topics of interest in the 1980s in the commercial and service geography in Korea. In the 1990s, however reserch in producer services has been active with growth of producer services in Korean economy. It is suggested that regional changes with progress of informatization and technology, changes of international trade and regional changes, development of efficient distribution system, role of producer services in regional development, and network of producer services are the major issues to be studied in the future in the field of commercial and service geography in Korea. Commuting, distribution of products, and transportation networks have been the major topics of research in transportation geography in Korea. Diverse quantitative techniques have been applied in the most of the researches in transportation geography. It is required that future studies in transportation geography should also focus on societal and behavioral issues, policy issues regional impacts of new transportation facilities, an analysis of transportation system at the global or international level. Since the 1980s economic geography in Korea has considerably progressed with publication of papers and books. The progress can be regarded as successful in quantitative aspect, but not in quantitative aspects. For the development of Korean economic geography in both quantitative and qualitative aspects, it is necessary to promote international collaborative researches and interdisciplinary cooperations. Attention should also be given to the research on changes in competitive advantages and economic restructuring, changes of economic space with the development of high technology and the progress of informatization. economic development and culture. and foreign regional studies.
