This study was conducted to analyze the productivity and economic feasibility of truss-limited tomatoes (Lycopersicon esculentum L.) grown at a high density in Cambodia during the rainy season. During the rainy season in Cambodia, due to excessive rain and very high temperature, tomatoes cannot grow well in an open field, leading to a greatly reduced yield. High density truss-limited cultivation (HDTLC) of tomatoes can shorten the growing season and increase yields. In conventional cultivation (control), tomatoes were transplanted at a spacing of 70×40 cm and harvested up to the 4th fruit cluster. In HDTLC, tomatoes were transplanted at a spacing of 20×20 cm or 25×25 cm and harvested up to the 2nd fruit cluster. Plant heights in HDTLC were higher than those in the control at 22 days after transplanting (DAT). At 39 DAT, plant heights did not differ between 25×25 cm and control. At 60 DAT, plant height, stem diameter, leaf length, and leaf width of the HDTLC were lower than those of the control. Fruit length and width were also lower in HDTLC compared to those of the control. However, sugar content was more than 19% higher in HDTLC compared to that in the control. Yield per plant of the control was the highest, but yields per ha in HDTLCs were 99% (20×20 cm) and 38% (25×25 cm) higher, respectively, compared to that of the control. No pesticides were used for disease control in this experiment. However, to ensure yield, it is recommended to observe the disease status of plants and spray pesticides at the appropriate time. The disease index (1: disease-free; 5: all leaves were disease-infected) of late blight (Phytophthora indestans) was significantly higher for 20×20 cm (4.5) and 25×25 cm (3.6) groups compared to the control (2.0). Income with 20×20 cm (5,668 thousand KRW) and 25×25 cm (1,863 thousand KRW) were 4.9 and 1.6 times higher, respectively, compared to that with the control (1,149 thousand KRW). So, we want to spread the HDTLC technology, which transplanting of tomato seedlings at 20×20 cm intervals and harvests up to 2nd fruit cluster, to Cambodian farmers.

As part of the KOPIA Paraguay Center rice pilot villages project, conducted from July 1, 2021, to the end of June 2024, this study examined the average yield and value of paddy rice harvested between January and April 2023 in five local rice pilot villages in Paraguay: Santa Rosa, Eusebio Ayala, Coronel Bogado, Santa Maria, and Yaguaron. The CEA-5K-PUNTA variety was planted in late August 2022 and subsequently harvested from January to April 2023. The farmers in the pilot villages received information on common pests, diseases, and weeds, including instructions on timing and the number of applications required for their control. They also received technical guidance on water management and weeding methods. The study found that the average yield per hectare in the pilot villages for the CEA-5K PUNTA variety in the 2022/2023 growing season was 794.50 kg/10a, compared to 477.17 kg/10a for the conventional variety IRGA 424 in the 2019/2020 season, which preceded the project. This indicates a 66.5% increase in yield per hectare for the pilot village farmers compared to the pre-project period (2020/2021). The analysis of paddy rice production value in the pilot villages, using the Difference in Differences method, revealed a 65.1% increase. Moreover, a financial analysis was conducted based on the addition of agricultural inputs to the paddy fields during the period from the end of August 2022 to January-April 2023. The analysis showed that the total cost was US$597.25 per hectare, while the gross income was US$1,685.3 per hectare. As a result, the net profit per hectare amounted to US$1,088.05.

This study was conducted to determine the optimal irrigation starting point by analyzing tree growth, physiological responses, fruit quality, and productivity in peach orchards. Seven-year-old ‘Kawanakajima Hakuto’ peach trees were used in an experimental field (35°49′30.4″N, 127°01′33.2″E) located within the National Institute of Horticultural and Herbal Science located in Wanju-gun, Jeollabuk-do. The irrigation starting point was set with four levels of –20, –40, –60, and –80 kPa from June to September 2022. While there were no significant differences in increase of trunk cross-section area and leaf area among treatments, shoot length and diameter decreased in the –80 kPa and –20 kPa treatments. The photosynthetic rate measured in August was highest for –60 kPa (17.7 μmol·m-2·s-1), followed by –40 kPa (15.6 μmol·m-2·s-1), –20 kPa (14.5 μmol·m-2·s-1) and –80 kPa (14.0 μmol·m-2·s-1). SPAD value measured in May and August was lower in the –80 kPa and –20 kPa treatments than in the –60 kPa and –40 kPa treatments. The harvest date reached three days earlier in the –20 kPa treatment compared to other treatments. The fruit weight was highest in the –60 kPa (379.1 g), followed by –40 kPa (344.0 g), –80 kPa (321.0 g) and –20 kPa (274.9 g). Firmness was the lowest in the –20 kPa treatment. The soluble solid content was highest in the –60 kPa treatment (13.3°Bx).The ratio of marketable fruits was highest in the –60 kPa treatment (50.7%) and lowest in the –80 kPa treatment (23.4%). In conclusion, we suggest that setting the irrigation starting point at –60 kPa could improve the fruit quality and yield in peach orchards.

This paper aims to propose a new systematic approach to analyze the factor productivity and to investigate those characteristics of factor productivity in operational and managerial perspectives. The Cobb-Douglas production function is adopted to estimate the labor and capital productivity. In estimating those productivities the data of The Research on the Actual Condition of Coastal Fisheries (RACF), especially those of Jeon-Nam Province are used. The statistical analysis of RACF data shows that the characteristics are a little bit different between labor and capital of the operational equipment in the coastal fisheries. The Cobb-Douglas type production function is useful in estimating the factor productivity, especially in case of ‘coastal Stow-net fishery’ even though the limited data is used. However, in case of ‘trap fishery,’ the Cobb-Douglas production function appears to have some limitations in estimation. This implies that estimating the factor productivities in fisheries employing broad perspectives and various methods are needed.

This study is aimed to figure out the productivity and variability of cage-aquaculture changes. According to the analysis, the productivity of major fish species has been increasing, except mullet. Although the regional productivity has decreased in the last two years, it has been on the rise considering as a whole. Gyeongsangnam-do showed the highest level of productivity by region. Productivity by species was also higher than other regions in the cases of rock fish, mullet and sea bream followed by productivity of Chungcheongnam-do. The production of marine cage-culture in Jeollanam-do is the second largest in Korea in value/weight while its productivity is lower than that of Chungcheongnam-do. When it comes to comparison by region, Gyeongsangnam-do shows the lowest productivity variation. And Jeollanam-do shows the second-lowest variation in productivity that is only about half of that of Chungcheongnam-do province. Thus, it is found that Jeollanam-do region has an advantage in management stability while its productivity is low. On the other hand, productivity by species was also analyzed. Gyeongsangnam-do has the highest productivity by species for rock fish, mullet and sea bream whereas rock bream productivity is the highest in Jeollanam-do. Therefore, it probably needs to reflect these results when choosing regional-focused incubation fish species.

Sorghum×sudangrass hybrid (Sorghum bicolor (L.) Moench, SSH) is one of the most important summer forage crop and it is widely used for silage in Korea. Agriculture is highly dependent on the climate condition and experiencing significant loss of productivity due to climate change. This study was conducted to investigate the correlation analysis between productivity of forage SSH and climatic factors in Central Northern region of South Korea for 3 years (2017 to 2019). Plant height and dry matter yield of SSH were significantly higher in Gyeonggi-do than Ganwon-do. The productivity of SSH is more closely related with temperature than other climatic factors. Maximum temperature and Growing degree days in May and June showed a positive correlation. However, correlation between production of SSH and precipitation was not clear in this study, but rainy days showed a negative correlation (0.42). In conclusion, temperature is most important climatic factor to the maintenance of plant yield.

In order to propose basic references for the policy making of fishing vessel fishery by Jeju Special Self-Governing Province, we have obtained the basic productivity through analyzing operating days and catches of 16 sample fishing vessels registered in Aewol port, the north of Jeju island in the year of 2011. In addition, to compare with the basic productivity of southern sea area in the Jeju island, that of 7 sample fishing vessels registered in Kangjung port was used. Around Aewol port, average operating days during the main catch period from July to October were over 15 days a month. A average daily catch of fishing vessels was minimum 21.0 kg in May and reached to maximum 54.5 kg in December, showing U-shaped catch pattern through the year. The trend formula of the average daily productivity (y) depending on a tonnage (x) of fishing vessels around Aewol port was described by the equation, y = 18.867 ln(x) + 11.001, and that around Kangjung port in the year of 2009 was understood to be y = 23.271 ln(x) + 25.715. As a result, it seemed that the productivity of fishing vessels around Kangjung port, operating in the southern sea area of Jeju Island, was much greater than that of fishing vessels around Aewol port in the northern sea area of Jeju Island. Especially, that of fishing vessels less than 10 tons was 35-40% more.

가나에서 벼는 옥수수 다음으로 중요한 주곡작물이다. 요컨대, 카사바나 얌에 비하여 보관이 쉽고 취사시간이 적게 소요되는 장점으로 인해 대도시의 바쁜 직장인들을 중심으로 쌀의소비가 늘어나고 있다. 이렇게 가나에서 쌀 소비량은 연간11.8%로 빠르게 증가하고 있는 반면 자급률은 46%에 불과해부족한 쌀을 외국으로부터 수입에 의존하고 있어 국내적으로국제 곡물가 상승에 따른 식량안보 이슈와 재정적인 부담이부각되고 있다.본 연구에서는 가나의 벼 생산성 증대를 통하여 현재15~20% 수준에 불과한 보급종의 생산과 활용도를 높이고자종자생산 및 유통·보급체계를 분석하고 가나의 현실에 적합한보급종 벼 생산을 위한 정책적 대안을 제시하고자 한다. 먼저가나의 벼 종자생산 및 보급체계를 분석한 결과 비공식 품종의 난립, 국내 품종육성 능력 미흡, 국가 품종 보급 및 관리기관의 업무과다와 재정 부족, 보급종에 대한 농민의 낮은 신뢰도 및 정보 부재, 신품종 구입 애로 등이 문제점으로 나타났다. 보급종 종자의 생산과 활용도를 높이기 위해서는 지역단위의 종자생산 클러스트를 구성하여 해당지역에 적합한 벼품종을 선정하고 수요를 파악하여 종자를 생산하는 Semi-informal system이 단기적인 관점에서 정책대안으로 필요할 것으로 판단된다. 또한 종자 판매시스템 개선 및 농업기술의 신속한 전파를 위해서 소셜네트워크 시스템(SNS)을 이용한 정보 제공체계 구축을 제안한다. 농촌지도소 위주의 클러스트 구축에 의한 보급종 생산은 종자의 수급량 예측이 용이하고 지역에 알맞은 적품종의 선정이 가능한 장점이 있다. 농촌지도소를 통한 종자판매는 보급종에 대한 농민의 접근성과 신뢰성 확보에 크게 도움을 줄 수 있어 보급종의 재배확대를 통한 생산성 향상에 기여할 수 있을 것으로 생각된다. 또한 공익적으로 제공하는 문자메시지나 음성메시지 서비스는 농민들에게 최신 품종정보나 영농관련 기술전파에도 활용될 수있을 것이다.

The method for study was proceeded with 4M analysis via video recording, one of the steps of separate team activities. Separate team activity is newly established concept, indicating what is modified and expanded partial process among previously existing 6-Sigma methodologies so that measures of various variables in the manufacturing production line are applied. The first procedure is a 4M analysis via video recording. firstly, consultant records videos for relevant process, conducting 4M analysis based on collected data to derive wasting factors in each process. Secondly, it is a procedure to derive and select proper measures, meaning that measures for removing wasting factors based on derived results are elicited, selecting a measure with high probability of application via negotiation between consultants and separate teams. The last procedure is an application of selected measures to real production line, reflecting an environment of production field to derive an effect of increasing practical productivity rather than a qualitative effect as a measure with trust and flexibility.

The goal of this study is to analyze an effect of productivity elevation. For the goal, the various methods of the productivity elevation were suggested and the system improvements were conducted. The S company was established in Ban-Wol Industrial Complex, Ansan-City, Kyonggi-Do on 2007. The company was hiring 22 employees. The main manufactures were heavy duty equipment parts and the amount of sale was two billion won on 2008. Problems which the company faced were ambiguous production target management and materials loss. To solve the problems, NCT work improvement and automatic welding were induced. There were steel saving of 3,780,000won/month and man-hour saving of 144,000won/month by redesign of the steel sheet for the NCT steel job. Also, changing from handwork to automatic welding, the man-hour saving for the welding job was 320M/H and saving of 4,225,600won/month. The others of systematic improvement for productivity elevation were usage of jig and daily equipment checklist.

Competitive capacities in terms of price are rapidly deteriorating since the 1990's due to the competition and rapid pursuit of surrounding nations, exchange rates, increased wages, and labor and management disputes etc. Therefore, this paper shows the significant contents of preceeding research, surveys the employees of small and medium manufacturers who implemented the Toyota production system to conduct various analyses to determine the effect of the operation achievements so as to propose methods to effectively implement the Toyota manufacturing system and maximize long term operational achievements.

Today's fierce competition and global economic recession make most of manufacturing companies in the world difficult to gain a profit. In order to survive such a environment and increase competitiveness, manufacturing companies have to continuously eliminate their wasteful factors through an efficient process analysis, improve quality of products, increase the flexibility of manufacturing processes. In this paper, we consider a case study for the Shanghai New Auto which is a subcontractor of MOBIS in China, to improve productivity by using therblig method, one of the motion analysis, to minimize the work-in-process inventories and to shorten the manufacturing cycle times. We also try to relocate the facility layout to increase the efficiency and flexibility of manufacturing processes.
