Opis:
A path-neighborhood graph is a connected graph in which every neighborhood induces a path. In the main results the 3-sun-free path-neighborhood graphs are characterized. The 3-sun is obtained from a 6-cycle by adding three chords between the three pairs of vertices at distance 2. A $ P_k $-graph is a path-neighborhood graph in which every neighborhood is a $ P_k $, where $ P_k $ is the path on $ k $ vertices. The $ P_k $-graphs are characterized for $ k \leq 4 $.

Opis:
Service areas are places next to the road that provide services to motorists like petrol stations, restaurants, hotels, etc. Rest areas are zones near the road with a parking and some facilities, such as toilets and picnic areas, which are employed by road users during their travels. These areas play a vital role in road safety as they are demonstrated to reduce fatigue-related accidents. Moreover, in toll motorways, usually used for long-distance travels, these areas become essential as they are the only place to have rest or access to services as leaving and returning to it in the same point implies additional costs. This fact was verified by a survey conducted to 124 motorists who indicated that, if it is not totally necessary or they have not planned it in advance, they would not leave the freeway. The aim of this paper is to analyze the facilities offered in rest and service areas and the distances between them in the paying motorway network of Poland. Average distance between service areas and any type of areas are reasonable. The minimum distance established in Polish law is fulfilled in all the motorways, except a stretch in the A-1. All the rest areas include toilets and all the service areas include petrol, shop, toilets and a cafe. Other facilities are not so frequently available. The maximum distances between areas are over recommendations from other countries, and hence, a limit is recommended to improve road safety in Poland.

Opis:
4M Overturned Pyramid (MOP) model is a new model, proposed by authors, to characterized MTS which is adopting epidemiological model that determines causes of accidents, including not only active failures but also latent failures and barriers. This model is still being developed. One of utilization of MOP model is characterizing accidents in MTS, i.e. collision in Indonesia and Japan that is written in this paper. The aim of this paper is to show the characteristics of ship collision accidents that occur both in Indonesian and Japanese maritime traffic systems. There were 22 collision cases in 2008–2012 (8 cases in Indonesia and 14 cases in Japan). The characteristics presented in this paper show failure events at every stage of the three accident development stages (the beginning of an accident, the accident itself, and the evacuation process).

Opis:
Humans are one of the important factors in the assessment of accidents, particularly marine accidents. Hence, studies are conducted to assess the contribution of human factors in accidents. There are two generations of Human Reliability Assessment (HRA) that have been developed. Those methodologies are classified by the differences of viewpoints of problem-solving, as the first generation and second generation. The accident analysis can be determined using three techniques of analysis; sequential techniques, epidemiological techniques and systemic techniques, where the marine accidents are included in the epidemiological technique. This study compares the Human Error Assessment and Reduction Technique (HEART) methodology and the 4M Overturned Pyramid (MOP) model, which are applied to assess marine accidents. Furthermore, the MOP model can effectively describe the relationships of other factors which affect the accidents; whereas, the HEART methodology is only focused on human factors.

Opis:
This paper deals with wastewater treatment systems placed in motorway service areas (MSAs). In the years 2008-2009 eight of such facilities installed on the stretch of the A2 motorway between Poznań and Nowy Tomyśl were examined and analyzed. The system consists of a septic tank, a submerged aerated biofilter and an outflow filter. The volume of traffic on the highway was analyzed, the amount of water use was measured and peak factors were calculated. On this basis it was concluded that the inflows to the wastewater treatment systems in many cases exceeded the nominal design values. Based on the analysis of effluent quality it was found that the effects of plant operation in large part did not meet the requirements. It was found that the bioreactor aeration system and the design of the suspension separator (outflow filter) should be modified. One of the solutions was to use the soil-reed bed for wastewater treatment. The treatment of wastewater from the MSAs is a task that must take into account the unusual character of these facilities and the atypical quality of the effluent.
Praca dotyczy systemów oczyszczania ścieków w Miejscach Obsługi Podróżnych (MOP) przy autostradach. Badano i analizowano 8 instalacji zamontowanych w MOP-ach przy autostradzie A2 między Poznaniem a Nowym Tomyślem. Systemy składają się z osadnika gnilnego, zanurzonego, napowietrzanego złoża biologicznego i filtra odpływowego. Analizowano natężenie ruchu na autostradzie, ilość zużywanej wody oraz jakość ścieków na wlocie i wylocie z bioreaktora. Na tej podstawie stwierdzono, że wielkość oczyszczalnie nie jest adekwatna do ilości i jakości dopływających ścieków. Stwierdzono, że jakość odpływu jest niezadowalająca oraz zaproponowano zmiany konstrukcyjne i technologiczne.
