In this paper, we give some common fixed point theorems for compatible mappings in metric spaces, and also give an example to illustrate our main theorems. Our results extend the results of S. M. Kang, Y. J. Cho and G. Jungck [9].

This paper presents an efficient distributed recommendation system using clustering collaborative filtering algorithm in distributed computing environments. The system was built based on Hadoop distributed computing platform, where distributed Min-hash clustering algorithm is combined with user based collaborative filtering algorithm to optimize recommendation performance. Experiments using Movie Lens benchmark data show that the proposed system can reduce the execution time for recommendation compare to sequential system.

Two bacteria strains were isolated from emaciated olive flounder (Paralichthys olivaceus) in aquafarm and were identificated as Vibrio harveyi (JV1) and Edwardsiella tarda (JE1), respectively. In the challenge experiments, we found 100% cumulative mortalities in all of olive flounder injected with JV1, JE1 or JV1+JE1 within eleven days after the injection. Two bacteria strains were reisolated from dead fish and were analyzed using the PCR method. In the physilogical analysis, the hematocrit, AST, ALT and cholesterol levels in experimental groups were increased significantly compared to those in control group, but the glucose, total protein and triglyceride levels were significantly decreased. Additionally, the lysozyme activity in the blood serum was decreased. The histopathological observations of the intestine showed that all groups had detachment and destruction of epithelial tissues except for the control group.

Twenty isolates resistant to seven quinolones were isolated from major rivers in Korea. All isolates had three mutations, Ser83$\rightarrow$Leu and Asp87$\rightarrow$Asn in GyrA and Ser80$\rightarrow$Ile or Ser80$\rightarrow$Arg in ParC and three isolates had an additional mutation Glu84$\rightarrow$Gly or Glu84$\rightarrow$Val in ParC. In addition, a clonal spread was not found in these isolates.

Blue-Min was initially developed as an adsorbent for harmful gas removal and recently improved to apply to livestock, agriculture and aquaculture as an assistant feed. In the Blue-Min treatment, growth of harmful algae (Cochlodinium polykrikoides and the others causing the red-tide in the ocean) were inhibited below 10% in comparison with control and coagulation removal of harmful alge with Blue-Min treatment was more efficient than that of yellow loess treatment. It would be expected that the Ble-Min can be useful for the extirpator against the red-tide organisms and restrain the toxic algal growth around the fish aquaculture using the assistant feed. Recently, its utility has become to be diverse as it was revealed that aquaculture productivity increase by its application and, in addition, that it improve the water quality or sediment conditions in the aquaculture of Chinese White Shrimp. When Blue-Min was treated with the proper dose, the growth inhibition of Microcystis aeruginosa and lsochrysis galbana, which are typical red-tide organisms in freshwaters and food organisms in aquaculture, respectively, were less than that of marine red-tide organisms, while their growth slightly increased with low concentration treatiment. In addition, polyunsaturated fatty acids (PUFA) content of I. galbana slightly increase with the Blue-Min treatment. Through our research, the Blue-Min has diverse and comples function against various biological organisms and is proved as a biological activator or depressor.
