Včelaření jako terapeutická aktivita v sociální práci
Kunecký, Jiří ; Hubertová, Lucie (advisor) ; Čihánková, Ivana (referee)
The bachelor thesis deals with beekeeping. It understands this activity not only in the first meaning, the agricultural activity itself, but it tries to show it as an option for psychological and social growth. The work tries to sketch out its dissemination in social farms, sheltered workshops, psychiatric clinics and gardens as well as on roofs in cities. Many case studies which took place here in the Czech Republic as well as in other countries are mentioned more deeply in the text. Surprisingly, such kind of beekeeping could be described as a trend of young people, especially in urban areas. The thesis wants to depict advantages and disadvantages of this therapeutic activity with special interest in description of its influence on the behavior of the people involved in the activity. Beekeeping as a social activity could grow in near future and may become one of the common methods used in zootherapy. However, the group of people interested in the kind of therapy is specific and should be described more in detail. It is the purpose of this work to do so. Powered by TCPDF (www.tcpdf.org)

Survey report on the condition assessment of the Church of the Holy Spirit truss in Telč
Kloiber, Michal ; Bláha, Jiří ; Hrivnák, Jaroslav ; Buzek, Jaroslav ; Kunecký, Jiří ; Hasníková, Hana
The survey described in this report contains the condition assessment of the truss of the Church of Holy Spirit in Telč. The stimulus for the survey report was an order from the parochial congregation ČCE in Telč. The order included a request to assess the condition and identify the extent of wood-decaying damage to the truss of the Church of the Holy Spirit in Telč, focusing on the location of the critical spots, the classification of the damage degree, the determination of the extent of hidden damage using non-destructive devices, and the specification of the wood damage cause, including drawing of the results in the documentation on the current truss condition. Based on the results, specific procedures of repair measures were proposed and the elements proposed for the reconstruction were sketched in the documentation.

Lapped scarf joints for reconstruction of historical structures
Kunecký, Jiří ; Fajman, P. ; Hasníková, Hana ; Kuklík, P. ; Kloiber, Michal ; Sebera, V. ; Tippner, J.
This paper presents a description of the repair of timber structures using a prosthesis scarf\njoint designed for the replacement of damaged parts of beams. This new scarf joint makes use\nof the strutting effect of inclined contact faces where the forces are transmitted through\nwooden coupling elements - wooden dowels or keys. The scarf can be modified in four\nvariants according to the relevant stress and is suitable for historically valuable timber\nstructures. It meets both functional and aesthetic requirements. The designer - structural\nengineer will learn in the methods the load bearing capacity or stiffness of the beam with the\ndesigned joint, its recommended dimensions and detailed geometry. The contractor will\nappreciate the description of the execution and maintenance of the joint.

The use of carpentry joints for the repair of historical structures
Kloiber, Michal ; Kunecký, Jiří ; Hasníková, Hana ; Sebera, V. ; Tippner, J. ; Fajman, P. ; Růžička, P. ; Stejskal, D.
The conservation process describes the way of using prosthesis lap scarf carpentry joints for reconstruction of historical timber structures. This new scarf joint makes use of the strutting effect of inclined contact faces where the forces are transmitted through wooden coupling elements - wooden dowels or keys. The process consists of several chapters describing the diagnostics of original wood and the repaired structure, the design of the joint and execution of the joint. It also includes examples of succesful reconstruction made with according to this conservation process.

Designing of all-wooden carpentry joints for reconstruction of historical structures
Kunecký, Jiří ; Hasníková, Hana ; Fajman, P. ; Tippner, J.
The article introduces the new method „Lapped Scarf Joints for Repairs of Historical Structures“ that deals with the design of the lapped scarf joint suitable for the reconstruction of valuable historical timber structures, with help of making the prosthesis for the damaged parts of the beams. The method is the result of the four-year research project supported by the Czech Ministry of Culture within NAKI program. Institute of Theoretical and Applied Mechanics AS CR, Faculty of Civil Engineering CTU and Faculty of Forestry and Wood Technology of Mendel University participated on the research.

The numerical assessment of a full-scale truss reconstructed employing a traditional all-wooden joints
Milch, J. ; Tippner, J. ; Sebera, V. ; Kunecký, Jiří ; Kloiber, Michal ; Navrátil, M.
The assessment of mechanical behaviour of all-wooden joints used in historical timber structures such as churches, castles etc. is currently paid a big attention in the Czech Republic, and Central Europe as a whole. The reasons are (a) a high number of such structures; (b) their significance to the national cultural heritage and maintenance for preserving their cultural value; and (c) missing information about global mechanical behaviour of joints and whole truss structures when loaded. Generally, valuable historical monuments need to be evaluated as regards the structure and safety of all timber elements in the structure for their future preservation [1]. The present paper shows a novel methodology for virtual assessment of mechanical behaviour used in a historically valuable gothic truss structure of St. James's Church in Brno, which is very valuable from both structural and architectural points of view. The church was constructed between1220 and 1724, the used styles including the Romanesque, the Gothic and the Neogothic. Also carpentry master Anton Ebenberger participated [2]. The aim of this paper was to describe the real loading of a joint that corresponds to the real function of a joint in the truss structure during the loading owing to new positions of replacement joints in the truss. Currently, the truss of St. James’s church shows large defects including decayed members; therefore, renovation is needed. The restoration of the truss should be carefully implemented in the structure and analyzed beforehand. Therefore, the numerical approaches based on FEM were used to evaluate the mechanical behaviour of the beam truss with a detailed 3D solid joint.

Influence of geometric parameters on the stiffness of traditional dovetail timber joint
Kunecký, Jiří ; Cacciotti, Riccardo ; Kloiber, Michal
The paper presents the development of numerical modeling for a traditional dovetail timber joint. The objective is to find the influence of its geometrical properties on the mechanical stiffness of the joint as well as to assess the main problems and limitations faced during the numerical modeling of the structure. An experiment with a replicated timber joint was used to validate the model. Material properties were ascertained and contact adjustment was made. Parametric study was performed: two angles of the joint beams were varied. Suitable ranges of the angles for each type of loading were found. Main limitations and problems present in the modeling are depicted in the discussion.

Numerické modelování ochranných sportovních přileb
Kunecký, Jiří ; Jíra, J.
The paper describes development of advanced methods used in research of protective devices. Explicit FE analysis is used for modeling of drop tests. Drop tests are one of common testing procedures used in the standards and are intended for testing of device's protective properties. If we were able to assess the acceleration history from numerical analysis with given geometry and material properties, we can also perform optimization procedure and design optimal protective helmet.
