In the aftermath of the global pandemic that started in 2019, there have been many changes in the import/export and supply/demand process of agricultural products in each country. Amid these changes, the necessity and importance of each country's food self-sufficiency rate is increasing. There are several conditions that must accompany efficient agricultural activities, but among them, temperature is by far one of the most important conditions. For this reason, the need for high-accuracy climate data for stable agricultural activities is increasing, and various studies on climate prediction are being conducted in Korea, but data that can visually confirm climate prediction data for farmers are insufficient. Therefore, in this paper, we propose an artificial intelligence-based temperature prediction algorithm that can predict future temperature information by collecting and analyzing temperature data of farms in Gyeonggi-do in Korea for the last 10 years. If this algorithm is used, it is expected that it can be used as an auxiliary data for agricultural activities.

Purpose: Self-sufficiency in paper production is desired in Nigeria. This study was aimed at evaluating the performance of a locally fabricated batch pulp digester. Methods: The pulp yields of sheaths generated as waste in the production of bamboo (Bambusa vulgaris) laminates were determined at different liquor concentrations and treatment time after preliminary experiments to ascertain the conditions under which the sheath started to pulp. Moreover, the optimum pulping conditions and fiber characteristics were determined and estimated, respectively, to ascertain the pulp fiber suitability for paper production. Results: An optimum pulp yield of 65.1% was obtained at 50% NaOH and 25% $Na_2S$ liquor concentration (w/w) when the cooking time was 4 h. The results of fiber characterization of the pulp indicated an average fiber length of 2.19 mm with a low Runkel ratio of 1.63, both of which signify the suitability of the pulp for medium quality paper production. Conclusions: Softwood pulp can be blended with the fibers to improve the strength of the produced paper; further investigation should be carried out to use other non-woody plants for pulp and papermaking.

Rice straw is the principal forage for Korean cattle. Limited supply of domestic forage forces Korea to depend on imported forage. Utilizing locally available domestic feed as an alternative would lead to self-sufficiency and stability in cattle farm management. Locally available feed can be utilized as forage. The challenge of collecting local feed has been overcome by machines that have been developed to harvest feed. Local feed can be completely consumed in the production regions, thus reducing transportation costs and increasing price competitiveness. Hitherto, studies have focused on feed technologies and price competitiveness, among other factors, while the substitution of forage has not been examined. This study conducts a quantitative analysis to estimate the extent to which local feed can replace existing forage. We find that local feed is cheaper, and abundantly available, and can thus replace high-quality forage.

The neutronic analysis of Helium Cooled Ceramic Reflector (HCCR) breeding blankets has been performed using the 3D Monte Carlo code MCNPX and ENDF nuclear data library. This study aims to reduce ⁶Li percentage in the breeder zones as much as possible ensuring tritium self-sufficiency. This work is devoted to investigating the effect of ⁶Li percentage on the HCCR breeding blanket's neutronic parameters, such as neutron flux and spectrum, Tritium Breeding Ratio (TBR), nuclear power density, and energy multiplication factor. In the ceramic breeders at the saturated thickness, increasing the enrichment of ⁶Li reduces its share in the tritium production. Therefore, ceramic breeders typically use lower enriched Li from 30% to 60%. The investigation of neutronic analysis in the suggested geometry shows that using 60% ⁶Li in Li₂TiO₃ can yield acceptable TBR and energy deposition results, which would be economically feasible.

As the global semiconductor supply chain falters, major countries are pushing to increase their self-sufficiency in semiconductors. In accordance with these global changes, R&D cooperation is evolving in the semiconductor industry. Previously, as for the case of Interuniversity Microelectronics Center (IMEC) in Europe, many cooperation initiatives were established regardless of nationality for improving productivity through measures such as reducing the time and cost required for joint research. Recently, however, cooperation aimed at strengthening one's own industry has been prominent, such as that led by Taiwan Semiconductor Research Institute (TSRI) and the United States National Semiconductor Technology Center (NSTC). Hence, the Korean semiconductor industry also needs to respond. Internally, technology localization should be promoted by strengthening the foundation for domestic R&D cooperation, while externally, it should expand close cooperation with companies from countries leading the semiconductor industry, such as the United States, Europe, and Japan.

The paper examined Southeast Asia as a whole and focused on similarities among countries composing what is now known as the Association of Southeast Asian Nations (ASEAN). In order to determine these similarities, the analysis focused on the fact that during World War II the whole of Southeast Asia was occupied by one political power: Japan. The policies the Japanese implemented in the region were to a degree very similar in terms of pressures and tensions that occurred in the different countries. The paper argues that these pressures and the responses of the various peoples of Southeast Asia instilled a nucleus of common identity in Southeast Asia as a whole. Basically, the policies that the Japanese implemented all over Southeast Asia were the following: the setting up regional administrations; the extraction of resources and emphasis on local self-sufficiency; the implementation of cultural Japanization; and local indigenization policies. The Southeast Asian responses that crystalized this joint Southeast Asian identity may be described as: accommodating and resisting the Japanese; commemorating portraying; and collectively remembering the era. The process of action and reaction between Japan and Southeast Asia was formative of this joint Southeast Asian identity.

Unstable crop production and distribution affected by climate change and COVID-19 pandemic has raised the food security concerns worldwide. In particular, Russia's invasion to Ukraine has blocked the grain trade such as wheat and com to importing countries, which has aggravated the situation. Korea has relied on foreign imports for about 80% of domestic grain demand, raising great concerns on food security. Considering situations related to Korea's food security, some points in view of a crop scientist are suggested and discussed as follows; 1) Domestic production of major grain crops should be increased through encouraging farmers by appropriate governmental subsidy programs 2) International corporation should be strengthened and diversified for sustainable overseas agricultural development and for stable import even in case of food crisis and emergency. 3) Self-sufficiency target should be specified by law so that more budget investments could be put to alleviate the food security concerns. 4) Technologies for climate smart agriculture and for competitive agricultural products should be developed aided by social and governmental support.

2012년 농림수산 식품부 자료에 따르면 국내 식용 옥수수 재배 면적은 약 15,000 ha, 생산량은 74,399 톤이며, 옥수수의 식량 자급률은 3,8%, 곡물자급률은 0.9% 내외로 소비량의 대부분을 수입에 의존하고 있다. 옥수수 전체 수입량의 75%가 사료용, 23%가 가공용으로 국내 사료 및 산업소재로서 중요한 위치를 차지하고 있지만 옥수수 수입대체 및 품종 개발과 관련된 국내 연구는 내수를 위하여 제한적으로 수행되어 왔기 때문에 그 동안 축적된 기술을 바탕으로 종자시장이 협소한 국내보다는 해외를 대상으로 한 기술 개발이 시급하다. 현재 동남아시아는 외국 투자 유치를 자국 경제 발전의 원동력으로 삼고 외국인 투자자에 대해 면세혜택까지 부여하며 각종 지원책을 내세워 투자를 유도하고 있다. 최근 동남아시아의 경제 성장과 더불어 노동임금과 토지임대료가 올라 농업이 점점 어려워진다는 얘기도 있지만 농업 기계화와 선진 영농을 접목시켜 노동생산성을 높이면 우리나라보다는 발전의 여지가 많이 남아있는 땅이다. 특히 세계적으로 축산물 수요가 증가하는 가운데 옥수수를 이용한 가공식품 및 사료작물의 활용은 좋은 아이템이 아닐 수 없다. 따라서 동남아시아를 대상으로 하는 해외식량기지로서의 가능성을 타진하고 해외 수출용 옥수수 품종을 개발하여 개발 품종에 대한 마케팅 판매 전략의 수립을 목적으로 진행된 결과는 다음과 같다. 1. 동남아시아의 주요 곡물 생산량 중 옥수수의 생산량은 1990년대를 기점으로 가축 사육 증가와 더불어 지속적으로 증가하고 있으나 옥수수 재배 농가의 재래종 사용 및 농사를 위한 기본 인프라 시설과 열악한 관개시설, 수확 후 관리기술의 미흡으로 단위면적당 생산성은 낮은 편이다. 최근 급속한 기후 변화로 인한 수량감소도 생산성을 저해하는 중요한 요인으로 작용하면서 내재해 다수성 교잡종 품종의 수요 및 요구도가 높아지고 있다. 2. 인도네시아는 1992년부터 3계교잡을 이용하여 개발된 품종이 보급되기 시작하여 2001년 부터는 단교잡 품종을 개발하여 보급하고 있고 캄보디아는 사료용 옥수수의 거의 대부분을 CP 캄보디아가 농가로부터 수매하여 사료를 제조하고, 농가는 이 회사로부터 옥수수 종자를 구매하여 재배하는 상호 유기적 관계를 유지하고 있었다. 2010년 이후 캄보디아의 주요 재배 품종은 몬산토의 DK8868, DK9955, 신젠타의 NK6326, NK7328, CP그룹의 CP333 등 여전히 다국적 기업 및 현지 로컬 기업의 품종이 재배되고 있었다. 베트남은 동남아시아에서 많은 양의 옥수수를 수입하는 대표적인 국가 중 하나로 1990년부터 2011년까지 평균 수입량이 수출량의 13배에 달한다. 또한 경제성장 및 육류소비의 증가로 인한 사료용 옥수수의 수입으로 베트남의 옥수수는 주변 국가에 비해 높은 시장 가격을 형성하고 있다. 이에 베트남 정부는 정책적인 투자로 생산 효율성 향상을 위해 LVN-10과 같은 다양한 개량종 품종을 개발하고 있을 뿐 아니라 해충저항성, 제초제저항성 품종과 같은 GM작물의 재배를 승인 하였다. 이는 2020년까지 지속가능한 농업을 장려하는 계획과 맞물려 GM작물을 30~50%까지 늘려 농산물의 품질을 개선하여 농촌소득을 증진시킬 계획이다. 3. 국내의 협소한 종자 시장 한계를 극복하기 위해 동남아시아에 우리 농업관련 기관이나 민간기업 등이 진출하려면, 현지의 투자환경과 여건을 사전에 조사하고 외국인과 외국기업에 관련된 법규 및 사례를 충분히 검토하여야 한다. 세계 굴지의 종자회사인 몬산토, 듀퐁, 신젠타 뿐 아니라 로컬 기업이 장악하고 있는 시장으로의 진입을 위해 기술, 품질 및 가격 경쟁력을 갖춘 신품종의 개발이 필요하다. 신품종의 개발은, 사전에 조사한 현지 시장 분석 마케팅 역량 및 정부의 투자지원 정책과 접목되었을 때 농산물의 해외 진출 성과를 기대할 수 있을 것이다.

Ginseng in Korea has not only the big production value but also till a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using 4P's(product, place, promotion and price). The main results are as follows. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable.
