Meanwhile, property management has transformed from a one-way management model to a comprehensive management efficiency model. The model of property management is also developing towards green property management.

A Game Theoretic Framework for Cognitive Radio Networks Using Adaptive Channel Allocation Spectrum
Abstract— In this research, we propose a game theoretic framework to investigate the behavior of the cognitive radio networks for distributed adaptive channel allocation. We illustrate two separate objective functions for spectrum sharing games, which capture the benefit of selfish users and cooperative users, respectively. Based on utility definition for cooperative users, we determine that the channel allocation problem can be formed as the potential game, and converges to a deterministic channel allocation Nash equilibrium point. Alternatively, no regret learning implementation is proposed for both scenarios. Also, it is pointed to have similar performance with the possible game when cooperation is expected, but with a higher variability beyond users. The no regret learning formulation is beneficial to accommodate selfish users. Non-cooperative learning games have very low overhead for information interchange in the network. We point that cooperation-based spectrum sharing protocol improves the overall network performance at expense of an extended overhead needed for information exchange.

Feeding Habits, Length-Weight Relation, and Growth Pattern of Snakehead Fish (Channa striata) from The Rice Field of Jejangkit Muara Village, Barito Kuala Regency, South Kalimantan Province, Indonesia
Abstract—The research about “feeding habits, length-weight relationship and growth pattern of snakehead fish which caught in rice field JejangkitMuara, South Kalimantan” had been done during June-August 2018which divides into two parts: rice field JejangkitMuara village, Barito Kuala regency, South Kalimantan province for sampling, and identification at Fish Nutrition Laboratory, Aquaculture Department, Faculty of Fisheries and Marine, LambungMangkurat University, Banjarbaru. The aims of the research were to analyze feeding habits, relation between length-weight and growth pattern of snakehead fish (Channastriata) which caught in rice field JejangkitMuara village, Barito Kuala regency, South Kalimantan province. The results of the research showed that the length-weight relation with formula W = 0.8191 L 0,7762with value of r = 0.321092 which mean that length-weight relationships indicated the pattern of negative allometric type of growth (b<3). Snakehead fish has the fish as their primary feeding habits.
