The article broaches important for hundreds citizens of the commune issues regarding registration duty that contains act of 10 April 1974 about the public records and IDs (Official journal of 2006 No 139, position 993 with later changes). The legal status of the homeowner with a civil viewpoint is soundly established. Also constitutional principle of property protection gives a strong base to think that property law is well protected. However between sphere dominium and imperium establishing the status of a administrative party to procedure about announcing ones departure – the homeowner who left the place of residence without fulfilling registration duty – in practice of the organs of self-government and the officials in justiciary brings lots of doubts. The present article treats about this issue. Complexity of the topic requires wilder analysis legally cognitive including important issues such as access to public information or regarding real-state register. The article connects useful consideration for administrative practices with theoretical observation on the subject of administrative party to procedure.

Introduction: Distance between competitors in fighting sports and their target have an influence on kinematics of motion and as an consequence, its effectiveness. Therefore, the aim of this study is to extent the knowledge about influence of effective distance affects velocity of an object after hit. Material and Methods: Analysis were performed based on captured data of a male competitor with black belt in taekwondo (age: 20 yrs., body mass: 65kg, height: 171 cm). During data capturing, he performed sport punch strike 3 times with his left upper limb, and 3 times with the right one. The target was a ping pong ball. Data capturing was performed in HML (Human Motion Lab). Results: Velocities of sport punch strike were in range from 6.20 -8.01 m/s. Significant increase in passed momentum to the object were in -between 1.12 -1.73 % of effective distance. However, when effective distance were in -between 3.70 -3.95%, there were significant decrease (nearly half) in velocity of hit object. Conclusions: Our findings allows to formulate assumptions for further analysis, which states, tha t when maximum velocity of a punch occurs closer to the moment of hitting a target ( ∆ d), the higher it will be in a moment of that hit (r=0.95; p<0.01). Therefore, it allows to assume, that the lower will be a value of ∆ d, the higher will be destructive f orce for target ( ∆ E)
