One of the important factors among the smart farm factors is environmental measurement. This study tried to design an environmental measurement monitoring system through Bluetooth wireless communication with LoRa using the open source programs Arduino, App Inventor, and Node Red. This system consists of Arduino, LoRa shield, temperature and humidity sensor (SHT10), and carbon dioxide sensor (K30). The environmental measurement system is configured as a system that allows the sensor to collect environmental data and transmit it to the user through wireless communication to conveniently monitor the farm environment. As libraries used in the Arduino program, LoRa.h, Sensirion.h, LiquidCrystal_I2C.h and K30_I2C.h were used. When receiving environmental data from the sensor at regular intervals, coding using average value was used for data stabilization. An Android-based app was developed using Node Red and App Inventor program as the user interface. It can be seen that the environmental data for the sensor is well collected with the screen output to the serial screen of Arduino, the screen of the smartphone, and the user interface of Node Red. Through these open source-based platforms and programs will be applied to various agricultural applications.

This study was conducted to understand current management status of 'day and night care' facilities and to explore the related factors with rates of operation of them. The nationwide mailing survey was conducted with structured questionnaires from July, 14, 2010 to July, 28, 2010. The subjects were 277 facilities (response rate 24.5%). Regarding the types of operating, 79.1% of faculties was run by cooperation, and 17.8% and 3.6% for individuals and national/public institutes respectively. The average of operation rate was 70.15%. National/public institutes showed higher in the rate of operation(79.08%) than 72.49% of cooperations and 57.78% of individuals. The number of manpower was not nearly different by the types of operating bodies, but the number of nurse was significantly different among them. The national/public institutions had 1.07 nurses while individual institutions have only 0.08. We found that facilities run by national/public institutes and founded before 2008 years showed higher rate of operation. In case of providing regular monitoring and evaluation services, and music program for patients showed higher rate of operation. In addition, the number of managers, social workers, and nurses increase the rate of operation. We suggest that quality management and monitoring program for the facilities which run by individuals or established after 2008 years would be developed. We also call for development of programs for facilitating utilization of 'day and night care' facilities such as expanding the family support.

Andhra Pradesh is one of the major groundnut growing states in India. A total of 182 groundnut samples collected at harvesting from farmers fields in five districts, namely; Anantapur, Chittoor, Cuddapah, Kurnool, and Mahaboobnagar, during 1999 and 2000 rainy seasons were evaluated for the presence of mycotoxins (both aflatoxins and zearalenone) and toxigenic fungi. In samples collected from each district, average seed infection by Aspergillus flavus and Fusarium spp. was 11.9-18.3% and 5.6-12.8% in 1999, and 9.5-14.1% and 9.4-11.9% in 2000, respectively. Among the samples collected, 20.3% and 16.5% were contaminated with aflatoxin in 1999 and 2000, respectively, and in 11.4% and 8.7% of the seed samples collected in two seasons, the aflatoxin content was >30 $\mu\textrm{g}$/kg. An alarming aflatoxin content of 851.9$\mu\textrm{g}$/kg was found in samples collected from Anantapur district during the rainy season in 1999. Zearalenone was not detected in any of the samples collected in 1999, while 2 out of 103 samples collected in 2000 were contaminated with 35.1 and 129.4$\mu\textrm{g}$/kg. Under in vitro cultural conditions, 35.8% of the 173 A. flavus isolates collected from the groundnut samples produced aflatoxins at concentrations of 94.3-1598.6 ng/$\textrm{m}{\ell}$ and 3% of the 266 Fusarium spp. isolates produced 98.1-847.3 $\mu\textrm{g}$/g of zearalenone. The results emphasize the need for a more systematic and regular monitoring of pre-harvest aflatoxin contamination.

The primary step for efficient control of viral diseases is the development of simple, rapid, and sensitive virus detection. Reverse transcription loop-mediated isothermal amplification (RT-LAMP) has been used to detect viral RNA molecules because of its simplicity and high sensitivity for a number of viruses. RT-LAMP for the detection of Potato virus X (PVX) was developed and compared with conventional reverse transcription polymerase chain reaction (RT-PCR) to demonstrate its advantages over RT-PCR. RT-LAMP reactions were conducted with or without a set of loop primers since one out of six primers showed PVX specificity. Based on real-time monitoring, RT-LAMP detected PVX around 30 min, compared to 120 min for RT-PCR. By adding a fluorescent reagent during the reaction, the extra step of visualization by gel electrophoresis was not necessary. RT-LAMP was conducted using simple inexpensive instruments and a regular incubator to evaluate whether RNA could be amplified at a constant temperature instead of using an expensive thermal cycler. This study shows the potential of RT-LAMP for the diagnosis of viral diseases and PVX epidemiology because of its simplicity and rapidness compared to RT-PCR.

Objectives: This study examined the effects of nutrition counseling by the nutrition care process (NCP) on diet therapy practice and glycemic control in patients with type 2 diabetes mellitus. Methods: The survey was conducted on 49 patients whose hemoglobin A1c (HbA1c) level ranged from 6.5% to below 10% among patients aged 30~60s with type 2 diabetes mellitus. Nutrition counseling by the NCP process was carried out twice: first nutrition counseling and follow up counseling. The questionnaires were composed of 54 questions in five fields (general characteristics, health-related behaviors, diet therapy-related items, dietary life, diet therapy-related knowledge, diet therapy-related barriers). Nutrition intervention in nutrition counseling was performed based on the individualized diagnosis of NCP. Results: All the subjects practiced self-monitoring of their blood glucose levels, regular exercise, and diet therapy after NCP-based nutrition counseling. Diet therapy-related knowledge and practice by the subjects were improved after nutrition counseling. While the intake of boiled white rice decreased, the intake of boiled brown rice and barley rice in the subjects increased significantly. After nutrition counseling, the weight and HbA1c of the subjects decreased. Conclusions: These results suggest that personalized nutrition counseling by NCP process is effective for diet therapy compliance and glycemic control of type 2 diabetic patients.

A significant proportion of the African continent is conducive for animal agricultural production, due to its historical experience and available resources to accommodate and nurture various indigenous and exotic animal species and breeds. With food security being a global challenge, animal products can play an important role as nutrient dense food sources in human diets, particularly in Africa. However, this does not seem to reach its full potential in practice, due to numerous reasons that have not been adequately addressed. Animal welfare reservations can be highlighted as one of the major contributing factors to the curbed progress. The consequences have been scientifically proven to affect product quality and market access. However, in the African community, the concept of animal welfare has not been fully embraced. While there are international animal welfare standards in the developed world, there are inherent factors that hinder adoption of such initiatives in most developing regions, particularly among communal farmers. These include cultural norms and practices, social ranking, socio-economic status, available resources, information dissemination and monitoring tools. Therefore, there is need to harmonize what is internationally required and what is feasible to accommodate global variability. The protocols followed to ensure and evaluate farm animal welfare require regular investigation, innovation and a sustainable approach to enhance animal productivity, efficiency and product quality. Additionally, investing in animal wellbeing and health, as well as empowering communities with significant knowledge, has a potential to improve African livelihoods and contribute to food security. This review seeks to highlight the concept of animal welfare in relation to livestock and food production in African conditions.

The practice of producing and transmitting TV programs with uneven loudness can harm audiences' welfare in the digital environment where audiences are entitled to be offered quality broadcasting service. The purpose of this paper is to investigate issues concerning the digital loudness policy institutionalized in Korea since May 2016, and to offer policy suggestions. This paper reviews previous studies on audience welfare in digital broadcasting, focusing on the close link between loudness policy and audience welfare. In order to explore the state of international policy, this paper examines loudness standards developed by international standardization organizations including ITU, ATSC, and EBU, along with loudness regulations in the US, the UK, Canada, Australia, Japan, and Korea, respectively. Based on the analysis, this paper suggests recommendations for policy makers and broadcasters. First, policies on mandating regular monitoring and establishing penality system should be established for broadcasters not to violate loudness standards. Second, broadcasters are recommended to collect audience feedback, to be equipped with loudness measuring devices, to offer personnel training programs, and to check the compliance of loudness standards when they outsource TV programs.

Pest monitoring through field surveys and surveillance helps in forecasting the population build up of pest. It reduces the load of pesticides application and forms the basis of Integrated Pest Management in sericulture. Common sampling techniques for quantifying pest populations and damage caused by them are reviewed emphasizing the need for quick and simple sampling methods. Various direct and indirect sampling methods for establishing pest populations are discussed and methods have been discussed to use indirect sampling method under IPM programme in sericulture. The use of pheromone lures and traps forms one of the important ingredients of integrated pest management, which calls for integration of all available methods in a cost effective and environmental friendly manner offering consistent efficacy. Silk-worms feed on the variety of silk host plants and spin cocoons. Each silk host plant is attacked in the field by number of insect pest species. Several pests are common to mulberry, tasar, oak tasar, muga and eri host plant but pest status and seasonal abundance differs from each crop. The key pests are serious perennially occurring persistent species which cause considerable yield loss every year on large areas and require control measure. Regular occurrence of minor pest is noticed but sudden increase in its population is not known. The occasional pests are sporadic but potential causing sufficient damage. Silk losses due to attack of all the pests have not been calculated. However, information on pest biology and ecology, and control practices being practiced is available but the period of outbreak of major pests and predators on silkworms and its host plant needs to be reinvestigated. Pest and predators forecasting based on surveillance information may provide an opportunity to minimize the losses, particularly to reduce expenditure involved in pest management.

In line with the advances in factory automation, various pieces of equipment are now operated in batch processes controlled by computers. However, many kinds of faults can occur in complicated and large systems, which can result in low productivity and economic loss. The reliability and safety of systems have been studied because of the difficulty of determining the severity and location of faults. Therefore, it is necessary to detect and diagnose such faults in order to guarantee the reliability and safety of the equipment. In this paper, a diagnosis method for the ball bearings of a hydraulic pump is applied using a vibration signal for the maintenance of injection molding equipment. The bearings' defects are selected as a main failure mode through a failure mode and effect analysis (FMEA). Usually, there are nonlinear and impulse components of vibration in a ball bearing with faults. For the effective fault diagnosis of a ball bearing, nonlinear diagnostic methods and time-frequency analysis are applied, in addition to the methods currently used, such as power spectrum, time series analysis, and statistical methods. As a result of this study, a failure diagnosis system is provided that is useful even for non-experts. This is a condition-based method that makes it possible to resolve problems in a timely and economical way, in contrast to the prior method, which required regular but wasteful maintenance based on the experience of expensive external experts.
