Laos People’s Democratic Republic (Laos) is a country selected by Korea’s priority foreign policy – New Southern Policy. It is also one of Korea’s 24 priority partner countries. The objective of this study was to understand the current status of rice industry and recommendations for improving rice productivity in Laos based on “Agriculture Development Strategy to 2025 and Vision to the Year 2030” published by the Lao government. In Laos, major crops are rice, vegetables, maize, coffee, cassava, sugar cane, and others. Laos achieved rice self-sufficiency in 1999. Its rice production reached up to 3,580,000 tons in 2018. It aims to harvest a total of 5 million tons of paddy rice with a target yield of approx. 1.5 million tons in 2025. Rice consumption per capita totals 160 kg/year in Laos, the highest in the world. The national nutrient program sets its targets as follows: of 2,600 kcal, a recommended daily calorie intake for adults, it aims to lower rice and starch, while increasing calories from meat, vegetables, fat, and so on. This shows that the rice policy is formulated with consideration of improving health of people in Laos as well as boosting rice exports. Based on the agricultural policy and strategy of Laos, it is viewed that the rice industry in Laos can advance further and produce results only when rice industry is linked to the following areas: economic development, farm size expansion, higher productivity through novel varieties and cultivation technologies, scaling-up of agricultural mechanization, greater efficiency in processing, and infrastructure expansions such as roads and reservoirs. If an ODA (Official Development Assistance) project takes a tailored approach considering its actor-specific characters and tasks, it is believed that the project can contribute to the goal of securing sustainability for the rice industry.

인공광 이용형 식물공장에서 인공광원의 전력 소모는 작물 생산 비용을 증가시키는 주요한 요인이다. 따라서 인공광원의 광 이용효율을 향상시키는 것은 식물공장의 경제성 확보에 중요한 사안이다. 본 연구의 목적은 다양한 스펙트럼을 갖는 백색 LED와 원적색광을 추가한 다양한 백색 LED에서 재배 된 이고들빼기의 생산성과 광 이용효율을 비교하는 것이다. 파종 후 3주된 이고들빼기 묘는 심지 이용 수경재배 시스템에 정식되었고, 기온 20 ± 0.1°C, 상대습도 60 ± 0.1%, 이산화탄소 938.2 ± 5.8μmol·mol -1 , 광도 PPFD 250.6 ± 0.6μmol·m -2 ·s -1 , 광주기 16시간으로 설정된 인공광 이용형 식물공장에서 5주 재배되었다. 광질 처리조건은 대조구로 식물재배용 3가지 백색 LED(CL 1, CL 2, CL 3), 백색 LED 그룹[Warm W(WW), Neutral W(NW), Neutral W + Red(NWR), Cool W(CW)], 원적색광이 추가된 백색 LED 그룹(WWFR, NWFR, NWRFR, CWFR)이 사용되었다. 백색 LED에 원적색광의 추가는 지상부 생육특성 항목(생체중, 엽장, 엽면적)을 증대시켰고 WWFR 의 지상부 생장이 유의적으로 가장 높았다. 반면에 원적색광의 보광은 엽록소 함량을 감소시켰고 플라보노이드 지수에는 영향을 주지 않았다. 재배기간 동안의 총 소비전력은 CL 1에서 가장 낮았고 WWFR의 총 소비전력이 가장 높았다. WW와 WWFR의 광 이용효율이 높았으며 백색 LED에 원적색광의 추가는 광 이용효율을 3–15% 증대시켰다. 따라서, 백색 LED 에 원적색광의 보광은 작물의 생산성과 광 이용효율을 향상시켜 작물의 생산비용을 감소시킬 수 있었다.

본 연구는 우간다 낙농업에 종사하는 197 농가를 대상으로 낙농 생산성 향상을 위해 선호하는 ODA 사업이 무엇인지를 파악하였다. 최고-최저 조정법(Best-Worst Scaling, BWS)을 이용하여 낙농분야 ODA 사업에 대한 우선순위를 결정하였다. 7개 항목 중 1순위와 2순위는 각각 『젖소개량』과『가축질병 관리』로 전체 효용에서 차지하는 1순위와 2순위의 효용은 각각 48.5%와 21.7%로 나타났다. 우리나라의 선진 기술과 지식을 활용하여 농가 선호도가 높은『젖소개량』과『가축질 병 관리』는 낙농분야 ODA 사업으로 실행할 가치가 있다. 본 연구는 ODA 사업 계획 수립에 필요한 기초적인 정보를 제공 하며 정량적 우선순위 결과를 고려한 우간다의 낙농분야 ODA 사업은 효율적으로 현지 주민 만족도 및 낙농 생산성 향상에 기여할 것이다.

큰느타리(Pleurotus eryngii)는 주름버섯목(Agaricales), 느타리과 (Pleurotaceae)에 속하는 담자균류로서, 큰느타리 생산량이 한국에서 약 49,000톤(‘18)으로 가장 많고 수출량은 약 7,500톤(’19)으로 팽이버섯 다 음으로 높은 대표적인 식용버섯이자 수출품목이다. 큰느타리 재배는 병 재배 시스템의 기계화·자동화가 정착되고 액체종균을 이용하여 대량접종 , 배양기간 단축이 되면서 대량생산이 가능하게 되었다. 현재 큰느타리 종 균배양소나 자가생산농가에서 액체종균을 이용하고 있으나, 표준화된 종 균제작 매뉴얼이 없고 500ℓ 이상 큰 액체탱크를 이용하기 때문에 오염발 생이나 배양 실패에 따른 피해가 다른 버섯에 비해 매우 크다. 이에 큰느 타리 액체 종균의 생산 효율과 안정성을 높이고자 우선 큰느타리 액체배 지 종류별 조성별로 균사생장력을 조사하여 적정배지를 선발하는 연구를 수행하였다.

This paper suggests a specific model that could efficiently improve the interaction and the interface between MES(Manufacturing Execution System) server and POP(Point of Production) terminal through electronic document server and electronic pen, bluetooth receiver and form paper in disassembly and process inspection works. The proposed model shows that the new method by electronic document automation system can more efficiently perform to reduce processing time for maintenance work, compared with the current approach by handwritten processing system. It is noted in case of the method by electronic document automation system that the effects of proposed model are as follows; (a) While the processing time per equipment for maintenance by the current method was 300 minutes, the processing time by the new method was 50 minutes. (b) While the processing error ratio by the current method was 20%, the error ratio by the new method was 1%.

Productivity improvement is one of the important goals which firms’ technology developments aim at. Firms’ improved productivity from technology development means that their inputs can produce more outputs through technology development, which makes firms’ productivity improvement from technology development more and more important in the age of technology advance and convergence like today. This research empirically analyzes the influence of the external technology collaboration network diversity on the productivity improvement of the small and medium-sized enterprises (SMEs) from technology development and the moderating effect of the chief technology officer (CTO)-driven technology development on this influence. This study constructs the research model reflecting the moderating impact of the CTO-driven technology development and tests it with the ordinary least squares regression through the IBM SPSS version 23 by using the 2,000 data about South Korean SMEs. This research empirically reveals two points. One is that SMEs’ external technology collaboration network diversity has a positive influence on their productivity improvement from technology development. The other is that the positive effect of SMEs’ external technology collaboration network diversity on their productivity improvement from technology development is moderated by the CTO-driven technology development. The two points revealed in this study present two meaningful implications in not only the practical but also academic point of view. The practical implication is that it is effective for SMEs to use CTOs in increasing their productivity improvement from technology development. The academic implication is that making technology collaboration with more diverse external partners can increase SMEs’ productivity improvement from technology development.

This study investigates application cases of facility management system model for enhancing facility productivity of industry filed around medium and small facility processing companies and finds the inefficiency of the existing management model. Following items are researched to seek out methods and measures to maximize facility productivity through empirical analysis by exploring and establishing a new management model. First, the empirical analysis, it is found that the overall equipment efficiency index used for facility productivity management in the companies has a difficulty being used as the index for it in actual medium-small processing companies. Second, a new facility management system model applying standard cycle time is suggested among facility management index system to measure facility productivity. Third, the empirical analysis is used to verify that developed facility management system model is a useful method to manage the facility productivity by applying the model to actual medium-small processing companies. Finally, it is necessary to implement comparison analysis on whether actual productivity enhancement induces a distinctly different result by using a new facility management index system model to be inhibited in this study.

This study empirically analyzes the effect of IT SME ventures’ external information network diversity on their production period reduction and productivity improvement generated from technology development. This research constructs a mediating model based on the open innovation perspective and tests it with the 138 samples of South Korean IT SME ventures based on the ordinary least squares regression. This research is expected to make a good contribution by shedding a new light on the following three points about the critical role of IT SME ventures’ external information network diversity in increasing their production period reduction and productivity improvement generated from technology development which has scarcely been illuminated in the extant studies in the field of the management of technology for SMEs. First, IT SME ventures’ external information network diversity positively influences their production period reduction. Second, the external information network diversity positively influences IT SMEs’ ventures’ productivity improvement. Third, IT SME ventures’ production period reduction partially mediates the influence of IT SME ventures’ external network diversity on their productivity improvement. These three fresh points are expected to provide useful theoretical and practical implications. Related to the theoretical implication, this research provides a fresh implication that IT SME ventures’ external information network diversity positively influences not only their production period reduction but also productivity improvement generated from technology development. Concerning the practical implication, this study suggests that the CEOs in IT SME ventures make strategic efforts to use more diverse external information sources in order to increase their production period reduction and productivity improvement generated from technology development.
