Tyrimo objektas ir problemos aktualumas Tyrimo objektas. Disertacijoje teisiniu požiūriu tiriamas vienas tarpšakinių teisės institutų – priesaika. Disertacijos tyrimas apima paprotinės ir pozityviosios teisės raidos etapuose susiformavusius teisinius santykius, atsirasdavusius ir tebeatsirandančius priesaikos instituto taikymo ir jo funkcijų įgyvendinimo srityse. Šiame darbe nagrinėjami istoriniai, lituanistiniai šaltiniai; nacionalinių, tarptautinių ir kitų valstybių teisės aktų normos, reglamentuojančios priesaikos institutą, taip pat šią temą nagrinėjanti Lietuvos teisės doktrina. Priesaikos teisinio instituto ir jo socialinio vaidmens tyrimas bendrąja prasme – tai vieno iš seniausių ir gilias tradicijas Lietuvoje turinčio teisinio instituto tyrimas. Priesaikos sampratos (sąvokos) pažinimas yra organiška teisės doktrinos, kaip vienalyčio darinio, dalis, tačiau šio instituto prasmė ir reikšmė teisės normose ir teorijoje (moksle) nėra plačiau tyrinėta. Šiuo tyrimu bandoma atskleisti socialinę teisinę priesaikos esmę, jos evoliuciją ir virsmą į tikrai talpų (vertybių ir atliekamų funkcijų požiūriu) teisinį reguliatorių, kuris laikytinas Lietuvos Respublikos Konstitucijoje įtvirtintų pamatinių vertybių koncentracija, o kartu ir jų veiksnumą užtikrinančiu įrankiu. Perfrazuojant prof. A. Vaišvilą, „aiškinant teisę (šiuo atveju – priesaiką, kaip koncentruotą teisės išraišką [išskirta disertanto] <...>, neužtenka pasakyti, kad teisė (priesaika) yra elgesio taisyklė (tai tik...

In the present paper one of the inter-branch law institutes namely – the oath is being under discussion. The treatment of the problem embraces the development of law from time honored stages up to the present state. Within the period the law terms has changed considerately and the process is still in progress, especially in the sphere of the implementation of its functions. In the given paper the objects of research are the historical and native Lithuanian sources; i.e. the norms of national, international legal acts and the acts of other states in which the oath institution is called upon, as well as the Lithuanian law doctrine dealing with this problem. The general approach to the research of the juridical Oath Institution and its social significance has a long standing tradition in Lithuania. The cognition of the concept of the oath is an organic element of the law doctrine, as an integral formation, however has never yet received a deeper research either in legal norms or in theory. The given paper is an attempt to reveal the juridical and social essence of the oath, its evolution and transformation into a really meaningful juridical regulation of values and its fitting functions. It ought to be a concentration of the fundamental values stated in the Constitution and at the same time – an instrument of the assurance of their implementation. Rephrasing prof. A. Vaišvila „when explaining law (in this... [to full text]

The AK4 rifle serves as the primary weapon for the Home Guard, an integral part of the Swedish Armed Forces. Introduced in 1964, the AK4 is the Swedish version of the Heckler &amp; Koch G3 and functions as a fully automatic assault rifle. Among its components, the handguard holds significant importance, providing stability, improving accuracy and control, and protecting the user from heat generated by the barrel. Recognizing the need for optimization, an employee from the ALTEN Group, possessing military experience and expertise in the AK4, launched a project to enhance the ergonomics and versatility of the handguard in a cost-effective manner. This initiative stems from the excessively high cost of commercially available handguards, making them financially unviable for replacing the original handguard of every AK4 used by the Home Guard personnel. This project aims to design and develop a next-generation handguard for the AK4 rifle that addresses the current limitations of the existing handguard. The primary focus is improving the shooter’s performance by establishing a comfortable shape of the handguard, reducing the weight, and enhancing its compatibility with accessories. Additionally, the aim is to ensure the handguard is cost-effective for mass production and meets the requirements set by the Swedish Defense Materiel Administration. To achieve the aims, interviews and a comprehensive user testing study was conducted, collecting quantitative data in the form of participant ratings and rankings for different design concept while also gathering qualitative data through participant feedback that highlighted specific design features contributing to comfort. Additionally, a systematic material selection process was performed, involving the analysis and ranking of various materials based on properties such as weight, price, and specific mechanical properties. Furthermore, the manufacturing analysis relied mainly on conversations with industry experts possessing expertise in the field of plastic manufacturing. Upon conducting a detailed analysis, it has been determined that the ideal configuration for the final product is an octagonal shape. After careful evaluation, Polyamide 6 reinforced with 30% glass fibers has emerged as the most suitable material choice for the handguard. This material had the optimal balance between mechanical properties, thermal performance, durability, cost-effectiveness, and environmental impact. To produce 50,000 handguard units, the recommended manufacturing method was injection molding due to its compatibility with mass production and the advice received from industry experts. Considering the design and selected material, a substantial number of the requirements outlined by FMV could be fulfilled by conducting both theoretical analyses and practical experiments.
