Innovative approaches of regional policy of rural tourism development

The present work intends to study Rural Tourism. More specifically: regional policy of Rural Tourism development. Purpose of this research is creation of innovative qualitative model of regional policy of Rural Tourism development for Ukraine. With this aim literature review was made, developed a research methodology and analysis made. It was established a way of creation of qualitative model, based on studied information and scientific papers. Research methodology was described in next part. Decided to do it in three stages: (1) justification of analytical research; (2) data sample collection and analysis; (3) creating of innovative model of regional policy of Rural Tourism development. Each of these stages have sub stages supported by results of previous. In accordance to methodology, analytical part was made in two steps: (1) analysis of statistical information about rural houses availability; (2) analysis of resources needed for successfully Rural Tourism activity. This part gave information about placement of rural houses by geographical regions and defined most attractive geographical regions for Rural Tourism development. The results showed that the highest rural houses availability is in Western geographical region. Other regions have low level of rural houses availability. However, analysis of resources needed for successful Rural Tourism development showed, that all geographical regions are attractive for organizing Rural Tourism activity. Based on this information an innovative qualitative model of Rural Tourism development was created.

Computational and experimental study of the behavior of cyano-based ionic liquids in aqueous solution

The solvation of cyano- (CN-) based ionic liquids (ILs) and their capacity to establish hydrogen bonds (H-bonds) with water was studied by means of experimental and computational approaches. Experimentally, water activity data were measured for aqueous solutions of ILs based on 1-butyl-3-methylimidazolium ([BMIM](+)) cation combined with one of the following anions: thiocyanate ([SCN](-)), dicyanamide ([DCA](-)), or tricyanomethanide ([TCM](-)), and of 1-ethyl-3-methylimidazolium tetracyanoborate ([EMIM][TCB]). From the latter data, water activity coefficients were estimated showing that [BMIM][SCN] and [BMIM][DCA], unlike [BMIM][TCM] and [EMIM][TCB], are able to establish favorable interactions with water. Computationally, the conductor like screening model for real solvents (COSMO-RS) was used to estimate the water activity coefficients which compare well with the experimental ones. From the COSMO-RS results, it is suggested that the polarity of each ion composing the ILs has a strong effect on the solvation phenomena. Furthermore, classical molecular dynamics (MD) simulations were performed for obtaining an atomic level picture of the local molecular neighborhood of the different species. From the experimental and computational data it is showed that increasing the number of CN groups in the ILs' anions does not enhance their ability to establish H-bonds with water but decreases their polarities, being [BMIM][DCA] and [BMIM][SCN] the ones presenting higher propensity to interact.
