This paper analyzes the beef cycle and forecasts the number of Hanwoo. This study uses Sine function for this purpose. Data shows that beef cycle varies from five to twelve years and the cycle becomes longer as time passes. The adjusted $R^2$ of the estimated model is 0.95. The forecasted value based on this model for the number of Hanwoo is 1.6-1.8 million heads in lower bound and 3.2-3.7 million heads in upper bound, where the peak points are slightly different according to cycles. These predicted values imply the instability of number of Hanwoo and corresponding farm income, so we have to prepare adequate policies to cope with it.

School food services using environment-friendly agricultural products (E.F.A.E) have been promoted by school food service center (S.F.S.C) of each county in Chungnam. Since Dangjin S.F.S.C was established for the first time in 2011, 13 S.F.S.Cs have been established in 13 counties of Chungnam. 9 S.F.S.Cs of them have been managed directly by each county and 4 S.F.S.Cs of them managed by contracted cooperatives. Price deviation of 8 foodstuffs (rice, radish, spinach, cabbage, scallion, onion, garlic and potato) which are consumed much relatively was showed differently by counties. And in the average price of 8 foodstuffs, that of foodstuffs produced within the county was lower than that of produced in Chungnam and domestic. Also, the coefficient of variation of school foodstuffs was lower than that of retail market because S.F.S.C has procured school foodstuffs by contract cultivation between each S.F.S.C and producers. Contract cultivation effected on E.F.A.E price stability and producers' farm income.

Agricultural production facilities that have been established to support improving food production, farm income, and reduction of farming time have remarkable achievements as value-neutral devices or infrastructures, but recently they are pointed out as a factor that hinders landscape by changing the contextual values of rural area. Despite this timelessness, research on the landscape design of agricultural production facilities has not been conducted until now. Based on these research necessities, this study aims to improve the process of reviewing the landscape of agricultural production facilities by analyzing the impact of activities, policies, plans. The results of this study are as follows. First, the analysis of the literature and the related data were carried out. This presents the structural limitations of why landscape review is difficult in the process of reviewing plans and the limitations of current landscape laws, deliberations, and plans. The process of reviewing the plan has formed a functionally oriented closed network, and the government policy does not properly control the landscape design of agricultural production facilities. From the viewpoint of the study, results can be used as basic data for the study of the lack of agricultural production facilities and landscape.

The purpose of this study is to identify the agricultural management characteristics of young farmers and to analyze the factors affecting the sales of agricultural products of young farmers. For the analysis, variables related to characteristics of agricultural managers and farm management were used, and cross tabulation analysis and multinomial logistic models were applied. The results show that young farmers have the advantages of high education attainment, high income, crop selection, large size of farmland and high utilization rate of information technology. However, the low rate of specialized farming, passive participation in producer organizations, and low availability of agricultural machinery can be disadvantages. Reflecting the characteristics of young farmers, policies should be established to make use of their strengths and to make up for their weaknesses.

Blueberry producers' management is failing as a result of the price decline caused by an increase in blueberry imports and the accompanying deterioration in management. Consequently, an endeavor was undertaken to verify the measurement and impact from the standpoint of efficiency and productivity of blueberry management, and to offer an indication of management improvement through analysis. Using the Rural Development Administration's income survey data, the data for twenty-four blueberry farms was analyzed. First, the management effectiveness of blueberry cultivators was evaluated. Using the CCR model (0.7297) and the BCC model (08148), the efficiency of a farm was examined. When the efficiency is one, CCR is ten and BCC is fifteen, and in overall, it was found to be ineffective, the efficiency declined from 2018 to 2019, but climbed again in 2020, according to the annual analysis. The MPI index was then used to examine productivity. T2's MPI index was 1.3338, whereas T3's MPI index was 0.8896, demonstrating a considerable decline in TC. This indicates that technological progress is not being accomplished, necessitating the need for countermeasures. In order to improve the management efficiency of blueberry producers, it is necessary to reduce costs and improve receivable prices through producer organization, and to actively introduce new technologies.

This study applied the macro-micro simulation model (i.e., what-if analysis) to investigate the impact of transport related to the Belt and Road Initiative (BRI) on poverty and income inequality in Laos. We selected Laos as a case study of a developing country. We used the standard GTAP model with the GTAP database (version 10) for the macrosimulation, whereas we used the household model with the latest Lao household data from 2019 for the microsimulation. Our findings revealed that the output of the Lao economy was anticipated to increase by up to 0.3%, while the poverty rate was anticipated to decline from 17.0% to 15.7%. However, there would be winners and losers in industries and groups of households in different areas. In particular, rich households with a comparative socioeconomic advantage, such as in education, engagement in nonfarm business, and infrastructure access, would mostly gain benefits; consequently, this would lead to higher inequality in Laos. Therefore, the inequality index (i.e., the Gini coefficient) would increase from 41.2 to 60.1. After a simulation of BRI transport, we also found that some nonpoor households, which are mainly associated with farm activities and lower educational levels, would fall into poverty.

As the population and income levels rise, meat consumption steadily increases annually. However, the number of farms and farmers producing meat decrease during the same period, reducing meat sufficiency. Information and Communications Technology (ICT) has begun to be applied to reduce labor and production costs of livestock farms and improve productivity. This technology can be used for rapid pregnancy diagnosis of sows; the location and size of the gestation sacs of sows are directly related to the productivity of the farm. In this study, a system proposes to determine the number of gestation sacs of sows from ultrasound images. The system used the YOLOv7-E6E model, changing the activation function from sigmoid-weighted linear unit (SiLU) to a multi-activation function (SiLU + Mish). Also, the upsampling method was modified from nearest to bicubic to improve performance. The model trained with the original model using the original data achieved mean average precision of 86.3%. When the proposed multi-activation function, upsampling, and AutoAugment were applied, the performance improved by 0.3%, 0.9%, and 0.9%, respectively. When all three proposed methods were simultaneously applied, a significant performance improvement of 3.5% to 89.8% was achieved.

Agrivoltaic System (AVS) was introduced with the concept that it could generate electricity by using the extra light remain after crops use for photosynthesis in farm, which can earn additional income. However, crop yield was declined under the AVS condition due to the decrease in light energy. In the past, many researchers have been studied about crop states under shading conditions. However, the phenomenon of partial shading such as under the AVS is not well studied. In this study, to figure out the response of crop under the different light conditions, the electron transport rate (ETR) and non-photochemical quenching (NPQ) of rice was investigated using the chlorophyll fluorescence measurement. Also, physiological changes of crops under the shading conditions were investigated. The growth experiment under partial shading under AVS and overall shading which made of 35% shade cloth was conducted to understand the eco-physiological responses of rice to light in terms of the photosynthesis. Under the shading conditions, SPAD value and chlorophyll contents were higher, but the leaf thickness was lower than control. The overall shading condition show lower ETR than others during the growing season. In contrast, NPQ was higher than other treatments. This means the available light energy cannot contribute to photosynthesis under the shading condition.

The purpose of this study is to analyze how the orchard scale improvement project affects the profits of apple farmers. For this purpose, the variable profit function of Apple was estimated using seemingly unrelated regression analysis. For the analysis, raw data from the Rural Development Administration's Agricultural Income Survey from 2015 to 2021 were used. Of the 1,009 apple farms, 95 farms participated in the orchard scale improvement project and 914 farms did not participate. The results show that the profits of farms participating in the project were found to be higher than those of non-participating farms, and as the cultivation area increased, profits tended to increase and then decrease. The results also indicated that below a certain size (19,462m²), the profits from project participation appear to be lower. The results of this study can provide useful information to the establishment of government policies and apple farmers who want to participate in the orchard scale improvement project.
