Recently, the importance of livestock statistics is increasing because of the food consumption pattern in Korea is changing. We compare the old sample design based on the 1995 National Agriculture Census with the new sample design based on the 2000 National Agriculture Census. We present some considerations to improve the efficiency of the sample design in livestock sector survey.

With promising results and enormous capability, deep learning technology has attracted more and more attention to both theoretical research and applications for a variety of image processing and computer vision tasks. In this paper, we investigate 32 research contributions that apply deep learning techniques to the agriculture domain. Different types of deep neural network architectures in agriculture are surveyed and the current state-of-the-art methods are summarized. This paper ends with a discussion of the advantages and disadvantages of deep learning and future research topics. The survey shows that deep learning-based research has superior performance in terms of accuracy, which is beyond the standard machine learning techniques nowadays.

In a survey conducted in March 2023, Euphorbia hypogaea plants cultivated within greenhouses in Yongin, Korea exhibited water-soaked areas near the stem base, close to the soil. Subsequent isolation from diseased E. hypogaea led to the identification of a bacterial strain, designated as CBNUMPBL-103. The isolate was identified as Dickeya dadantii through sequencing of the 16s rRNA and phylogenetic analysis. The pathogenicity of the isolate was confirmed by inoculating it into healthy E. hypogaea, resulting in the manifestation of similar symptoms observed during the survey. The re-isolated strain recovered from inoculated plants showed a similar morphology with the inoculated strain. This is the first documentation of D. dadantii causing soft rot of E. hypogaea in Korea.

In this paper, we surveyed the service system disclosed by the government and self-governing province to analyze the status of IoT data service. Survey conditions were focused on data generated from objects such as sensors, OpenAPI that can utilize the generated data and data having a data update cycle of less than 1 month. As a result of the survey, the ratio of IoT data to data released by the government, self-governing province and the private sector was only 1.2%. Therefore, in order to increase the utilization with the development of IoT technology, a dedicated organization that can manage the IoT data service is needed.

The purpose of this study is to analyze the patterns of farming materials required for creating and operating elementary school vegetable gardens and to propose a plan for vitalizing business related to urban agriculture. As a result of the survey, the farming materials purchased most for the operation of the school gardens were seeds materials focused on seedlings, compost/fertilizer, and farming tools focused on trowels, sprinklers, and hoes. Purchases of farming materials were made mostly through the internet, while most purchases of seedlings were made in pesticide stores. Therefore, it is necessary to provide information and education related to the use of farming materials. Thus, establishment and maintenance of highly accessible and reliable internet sources are recommended to provide the lists of farm products necessary as well as related information to help users in purchase and use in order to create and operate the school garden. In order to supply high-quality seedlings, it is necessary to provide information and education on the kinds of seedlings, management, cultivation, delivery methods, and the like, focusing on pesticide stores producing and distributing seedlings. Providing such information for participants will improve their satisfaction. Also, if businesses related to urban agriculture use these study results in producing, preparing, managing and selling seedlings and farming materials, they will also be able to generate profits and vitalize urban agriculture.

To investigate the degree of individuals' concept and awareness of insects, a survey study was conducted with students and adults living in Korea. The misconception rate for insects was about 50% for both students and adults, but it was lower for students and people who had experienced insect-related events than for adults and those who had not. The highest misconception rate was obtained in answer to a question about the basic structure of an insect. Most people had a high awareness of insects. Significant differences and correlations for the awareness of insects were found between students and adults, men and women, people who had experienced insect-related events and those who had not. The experience of an insect-related event most influenced awareness of insects. These results suggest that increasing people's interest in insects and utilizing insects in treatment situations may be beneficial for the field of mental healthcare.

This study investigates how visual appearance of pork cuts affects consumer preference. Images of pork belly, Boston butt, and loin were chosen on the basis of visible fattiness and used to analyze consumers' perception of the appearance of each pork cut. Meat color and visible fat proportion of images of pork cuts were analyzed by the researchers before conducting the survey. A total of 211 pork eaters evaluated the pork cuts based on appearance (lightness of color, redness, visible fat proportion, and fat distribution), preferability, and overall acceptability. Also, muscle pieces from different pork cuts were taken and the relative area composition of muscle fibers was measured. Based on survey results, correlation between visual traits and preferences of each pork cut was analyzed. The survey results showed that preferred pork appearance varied as per each individual's favorite pork cut. Also, the respondents evaluated visual characteristics and preference for each pork cut differently possibly due to the different visual characteristics of each cut. Correlation analysis between visual traits and preference indicated that overall acceptability of pork cuts was mainly influenced by fat preference, followed by color preference. Fat and color preferences for each pork cut were affected by various visual attributes including redness, lightness of color, visible fat proportion, and fat distribution, but their effects were considerably varied among different pork cuts. Thus, Korean consumers perceived and assessed pork appearance using various quality cues but the evaluation depended on which cut was being observed.

In Korea, many local governments has hosted the agriculture and/or food EXPO for the promotion of agro-food industry. Some EXPOs were successful to achieve their initial goal, but others were severely criticized due to wasting budget without outcome. The comprehensive debates and studies for the better management of EXPOs are required. The purpose of this paper is to analyze users for Jinju international agriculture & food EXPO 2013 and to suggest the strategies for the development of this EXPO. Survey analyses for two groups (enterprises and audiences) were conducted for this research. The results of studies present a few findings: First, the differentiated strategies for each groups (enterprises and audiences) should be developed. Second, EXPO need to attract more participants from the whole country. Third, the methods of advertisement should be improved, especially on-line ads. Fourth, various complains from participants, which are collected via surveys, need to be handled.

The purpose of this study is to analyze the performance of the fig farms based on the survey data. The survey of 12 farms was conducted during the period from August to September. The result shows that the productivities of land and the productivities of labor of the developed nutriculture farms are higher than those from traditional conventional culture farms and nutriculture farms. Incomes of the developed nutriculture farms are also higher.
