The combination of biological and physical/chemical technologies is a promising technique to reduce highly concentrated pollutants in livestock wastewater. It is suggested to treat livestock wastewater efficiently as follows: firstly, biodegradable organic matters, nitrogen and some of phosphorus should be removed by a biological treatment process and then residual non-biodegradable organic matters, color and phosphorus be eliminated by physicochemical technologies. In this study, therefore, the integrations of chemical coagulation, activated carbon adsorption, Fenton oxidation and ozonation were evaluated to provide appropriate post-treatment processes for biologically pre-treated livestock wastewater. After chemical coagulation followed by ozonation or Fenton oxidation process, the quality of treated wastewater could meet the discharge limit in Korea. However, a yellowish brown color still remained in the treated wastewater after a single method such as coagulation and Fenton oxidation was applied. The ozonation was found to be the most effective technology for the decolorization. Neither simple biological nor physicochemical treatment provides adequate decolorization and sufficient depletion of organics in livestock wastewater so far. Consequently, the integration of Fenton oxidation and ozonation with a biological treatment process is recommended to treat livestock wastewater in terms of removal efficiency.

Although the livestock excretion is a significant resource in providing nutrients to the crops as it is recycled, it has been perceived as the cause of environmental pollutions for its inappropriate treatment and quality control issues. The study is aimed to develop an integrated management system for efficient management of livestock excretion using the Ubiquitous technology, and the user requirements are analyzed for development of such system. As the result of analysis on the requirements, it has been proved that such system is perceived to be necessary and the demand for several main functions can be seen as well.

Korea has been managed HACCP with food and livestock products separately, but it was incorporated into food and livestock product safety management certification standard in 2015. Currently, the notification is unified, but food sanitation act and the livestock products sanitary control act are not unified. These differences are leading to complaints from food and livestock corporation. In this review, the food sanitation act, enforcement regulations of the food sanitation act, the livestock products sanitary control act and enforcement regulations of the livestock products sanitary control act were compared and analyzed to identify the part which requires unification. As a result of the survey, the thirteen clauses were proposed to unify in the food sanitation act and the livestock products sanitary control act. The nineteen clauses were proposed to unify in enforcement regulations of the food sanitation act and enforcement regulations of the livestock products sanitary control act.

Odor control for livestock and compost facilities has focused on manure handling and treatment during storage and land application, however, large amount of malodorous air is emitted and it is one of main sources of malodour in livestock farming. Biological treatment or biodegradation involves converting an organic contaminant to carbon dioxide and water using natural bacteria. Biofiltration is an effective air pollution control technology that uses microorganisms to breakdown gaseous contaminants and produce innocuous end products. Investment and operating costs on the biofiltration are lower than for thermal and chemical oxidation processes. This paper is intended to provide an overview of basic design and operating criteria for biofilters to control odors from livestock and compost facilities.

PEB system is more economical when compared with structures commonly used Hot rolled and welded light H-beam was introduced in the Standard Livestock Housing. This study suggested more economical technology for structural design by the reduction of live load, relief of deflection limit and reduction of importance factor. And, when applying wind Load as a result of examination with Low Rise Building Systems Manual considering open model, we can know that when the wind load is big, enclosed model is more stable than open model. In short, Suggesting more economical model and providing the method to reduce natural disaster, by the application of PEB system and the development of technology for structural design, are considered to strengthen the competitive power of farmhouse.

The aim of this study was to produce Aminotosan$^{(R)}$ fertilizer using optimized chitosan coagulant from waste livestock blood. Amino-acid fertilizer was produced by pretreated livestock blood. Chitosan coagulant was aggregated with amino-acid fertilizer to produce Aminotosan$^{(R)}$. Optimized coagulation conditions were set using chitosan coagulant such as 10% citric acid and 500 ppm chitosan coagulant by analysis of CST and TTF. The efficiency of coagulation by chitosan coagulant under the optimal conditions was better than chemical coagulants. After solid/liquid separation for coagulated amino-acid fertilizer, Aminotosan$^{(R)}$ fertilizer which added eco-friendly and aesthetic functions was produced.

This research aims to propose a ubiquitous integration monitoring system for the feeding and environment management of livestock production. The integration monitoring system proposed in this research is based on an integrated platform, and consists of livestock shed environment monitoring system, livestock monitoring system, livestock remote medical treatment, and feeding and management system. This research conducts the followings. First, we review the previous researches on livestock related ubiquitous monitoring system to examine the factors to be considered in the proposed system. Then, we design the system and implement the prototype to demonstrate the possibility of the application of this system to real stockbreeding environment.

Customary agriculture seeks to increase production and supply people with safe foods. Thus. the promotion and establishment of organic agriculture are required to reduce water and soil pollution caused by customary agriculture. Although organic agriculture is an agricultural technology system whose basic principle is organic water circulation in agronomic agriculture and livestock industry. the livestock raising sector has not been developed in Korean organic agriculture: hence the limited development of agronomic agriculture. This study therefore sought to develop a standardized model connected with organic livestock raising and organic agronomic agriculture to secure symmetric and continued development. Specifically, this study reviewed the technological and economic problems related to the development of a naturally circular standard model where organic agronomic agriculture and organic livestock raising are connected. Likewise, a model for calculating the appropriate quantity of fertilizers to be applied and appropriate number of livestock to be bred was proposed as important factors in the development of a regionally circular agriculture model, and an alternative to a system connecting the two factors suggested.
