This paper is derived from a survey research project investigating consumer attitudes towards organic food as the farm animal welfare. Presents focus group results on consumer perceptions, attitudes and recognition about farm animal welfare. We are aimed to conduct the survey research to evaluate the consumer's perception and demands of the farm animal welfare. We deals with the findings obtained from extensive interviews with a representative samples. The objectives of interviews included 20~60 year-old ages lived in Yongin, Anyang, Gunpo, Ansan, Seosan, Dangjin, Iksan and Jeonju city. Questions focused on how people were recognized the need and policies of farm animal welfare. Questionnaire and technical data are analysed and summarized. As the results of the survey research, the objectives of interviews had poorly understood about the policies of farm animal welfare. Conclusionally, the promotions of farm animal welfare policies were need. The development of farm animal welfare policies were desirable for the establishment of animal welfare.

Pusan has experienced some different paths of urbanization and industrialization compared to other cities, and has faced the problem of over-saturation in environmental capacity. Pusan needs to find out sustainable development strategies based on Agenda 21 by UNCED in 1992 to secure urban renewal. Therefore, Pusan`s sustainable development strategies focus on the 1)research on environmental capacity and reasonable population accommodation 2)supply of basic environmental facilities for the human settlement 3)protection and efficient management of environmental pollution 4)saving and control of energy and other resources 5)independent and stable execution of plan based on biological relation 6)harmony between nature and urban spatial organization. In addition, these policies can be suggested along with the conclusions; First, establishment of green plan-middle and long term environmental goals included in the urban planning to reduce environmental deterioration and pollution. Second, computation of sustainability index-the index is necessary to sustainable urban development, which is related with green GNP of the national level. Third, capacity estimation of nature and social environment-estimation of environmental capacity to the civilized area is required become an ecopolis, and is required to focus on the western area of Pusan which has high degree of potentiality.

The increase of population and industrial activities had brought into eutrophication in the Nakdong river. A remarkable acceleration of eutrophication brought about serious problems for water supply. Therefore, for the purpose of conservation of water quality in the Nakdong river it is necessary to control nutrients. MBOD method was used to evaluate algal growth limiting factor and algal growth potential in the Nakdong river from June to August 1994. The modified biochemical oxygen demand(MBOD) depends on the amount of available inorganic nutrient and organic substrate during 5 day incubation in the dark at 20℃. The MBOD assay depends on inorganic nutrients such as P and N as well as reduced carbon and called the MBOD, the MBOD-P, and the MBOD-N, respectively. The results of bioassay by MBOD(Modified BOD) method showed that the MBOD, MBOD-P and MBOD-N value were found to be in the ranges of 3.8∼96.0 ㎎O_2/ℓ, 5.6∼94.0 ㎎O_2/ℓand 42.0∼220 ㎎O_2/ℓ, respectively. And the the bioassay value was found to be the highest in Koryong area and the lowest in Waekwan area throughout the Nakdong river. The variations of MBOD-P and MBOD-N value showed similar tendencies to the variations of phosphorus and nitrogen value, respectively. By MBOD method, the relationships of MBOD, MBOD-P and MBOD-N value were MBOD ≒ MBOD-P ≪ MBOD-N. The MBOD value was nearly equal to the MBOD-P value, and the MBOD-N value was 3 to 20 times more than the MBOD-P value, approximately. Therefore, in the Nakdong river, phosphorus was the limiting factor for algal growth during summer season. The algal growth potential as the concentration of chlorophyll-a in the summer was maximum 5 times more than standing crop as it.
