Article 9 of the Japanese Constitution conditions the international activity of Japan after the World War II. The norm stating the renunciation of war and military forces was written into the constitution aimed to limit Japanese militarism. However, it became a burden for both the Empire and the international community. Since 1990s wider and wider interpretation frames have been used in order to realize allied responsibilities with the USA and to maintain the national security as new threads arose. Therefore, we deal with an existing constitutional regulation with is practically dead because it can be interpreted so widely.

Zasadniczy uwarunkowaniem międzynarodowej aktywności Japonii po zakończeniu II wojny światowej jest artykuł 9. Konstytucji. Zapisana w ustawie zasadniczej norma o wyrzeczeniu się wojny i posiadania sił wojskowych miała na celu ograniczenie japońskiego militaryzmu. Jednak z biegiem czasu stała się obciążeniem nie tylko dla Cesarstwa, ale i społeczności międzynarodowej. Od początku lat 90. XX wieku, w imię realizacji zobowiązań sojuszniczych z USA czy zapewnienia bezpieczeństwa narodowego, w dobie zmieniających się jego zagrożeń, tworzono coraz szersze ramy interpretacji tego zapisu. Mamy więc do czynienia z funkcjonującym zapisem konstytucyjnym, który poprzez szeroką interpretację jest w praktyce zapisem martwym.

There are hardly any publications that treat about relations between European Union and Japan. Those not numerous that present this topic, focus on economic side of the dialog. Whereas, although undisputably commerce is a vital part of relations between these two partners, the political aspect of them also exists. What is more, EU and Japan take steps towards the developmet of this field of relations especially during each year summit meetings. They act together in such areas as regional cooperation, protecion of environnement, conflict prevention and fight against poverty. They also present joint opinions about international prolems. Some crucial conditions of EU’s and Japan’s foreign policy make them potentially important partners in politics. The growing awareness of this in EU and Japan makes it highly probable that this dialog will reach in importance in coming years.

This article discusses a survey to investigate the problem of the health literacy of leisure runners. The survey was conducted in 2016 in Poland among 963 participants of the DOZ Marathon Lodz with PZU [Polish Insurance Company] . A specially developed scale for measuring the participants’ level of health literacy (−3, 23 points) was used, and the survey answers were evaluated by medical doctors. As the average score was 3.16, the surveyed population was shown to lack information about the medical and health consequences of running. The people who were relatively better informed were women and younger runners (and additionally single runners and those not active on the labor market). An unexpected finding was that social-class affiliation, educational level, and advancement in running ability had a low degree of influence on the health knowledge of the surveyed runners. The conclusion is that a health-related motivation to train in the sport of running (which was declared to be a key factor in many studies) is grounded in common knowledge, while the majority of leisure runners are unacquainted with the actual risks and benefits of running

Objectives: The aim of this study was to investigate the cyto- and genotoxicity of nanocomposites (NCs) and generation of reactive oxygen species (ROS) as a result of particle-cell interactions. Materials and Methods: Titanium dioxide (TiO₂-Ag) and ion-exchange resin (Res-Ag), both coated with silver (Ag), were examined. The murine macrophage J774A.1 cells were incubated in vitro with NC at different concentrations for 24 h. Cytotoxicity was analyzed by the methylthiazolyldiphenyltetrazolium bromide reduction test (MTT reduction test). ROS generation was assessed by incubation of cells with dichlorodihydrofl uorescein diacetate (DCF) and fl ow cytometry. DNA damage was detected by comet assay and included single-strand breaks (SSB), alkali-labile sites (ALS) and oxidative DNA damage after formamidopyrimidine glycosylase (FPG) treatment. The tail moment was used as an indicator of DNA damage. Results: TiO₂-Ag was not cytotoxic up to 200 μg/ml, whereas IC₅₀ for Res-Ag was found to be 23 μg/ml. Intracellular ROS levels were elevated after 4 h of exposure to Res-Ag at the concentration of 50 μg/ml. Both types of NC induced fragmentation of DNA strands, but only one of the composites caused damage to purine bases. TiO₂-Ag induced SSB of DNA at concentrations of 10 and 5 μg/ml. For Res-Ag, a concentration-dependent increase in tail moments was observed. Conclusions: Silver-coated nanocomposites (both TiO₂- Ag and Res-Ag) may cause genotoxic effects in murine macrophages J774A.1. Res-Ag increased generation of ROS which suggested that toxicity of Res-Ag in murine macrophages is likely to be mediated through oxidative stress. This paper will support industry and regulators alike in the assessment of hazards and risks and methods for their mitigation at the earliest possible stage in material and product development.
