Online Tourist Information in the Largest Polish Cities

Purpose/Thesis: This paper analyzes selected tourism websites for the largest cities in Poland. The paper answers following research questions: are the different websites designed to provide the tourists the relevant information?; do local conditions shape the content provided on these websites?; are these websites multilingual?; do they suggest possible itineraries?; how do they develop?Approach/Methods: The article uses comparative quantitative and qualitative analysis to study the information systems employed by the websites of the largest Polish cities: Warsaw, Krakow, Lodz, Wroclaw, Poznan and Gdansk. These cities are popular tourist destinations; each has an information system, reflecting the specific tourist services they offer.Results and conclusions: The organization scheme for each website is different, despite the fact that they were all designed for related organizational entities gathered in the structure of Polish Tourism Organization. Each site has a different design and appearance; different resources were dedicated to each. They are more varied than the websites of the analogous organizations operating in countries such as Germany, the Netherlands, and Sweden. The specificity of the region has more of an impact on the content offered to the user. In recent years, more flat websites, imitating the paper guides, were gradually replaced by multimedia platforms enabling various interactions with more dynamic content.Originality/Value: To the best of the author’s knowledge, the research presented in the paper is the first attempt to characterize and compare tourist information websites of the six largest cities in Poland.

Analisis Sistem Pengukuran Getaran Mems Accelerometer ADXL345

Vibration measurement technology using conventional sensors such as piezoelectric (PZT) Accelerometer is still expensive. Currently, many low-cost vibration measuring devices have been developed by using Micro Electro Mechanical System (MEMS) technology. This study aims to analyze the results of vibration measurement system MEMS Accelerometer ADXL345 with PZT Accelerometer. This research applies design and develop approach with comparative data analysis technique, that is comparing data of result of measurement of MEMS Accelerometer ADXL345 to PZT Accelerometer Vibroport80. The construction comprises the ADXL345 sensor connected to the Arduino Mega 2560 microcontroller operated by Widows operating system and programming language Arduino IDE 1.08. Testing of measurements at Bearing speeds of 500, 1000, and 1500 RPM with length of time measurements at 5, 10, and 20 seconds respectively. The analysis of the test results shows that the MEMS Accelerometer ADXL345 of vibration measurement system can measure, process and display vibration measurement data larger 3% than PZT Accelerometer and can provide the best measurement accuracy at 20 seconds measurement length of time.

SUSTAINABLE CONSTRUCTION TAKING INTO ACCOUNT THE BUILDING IMPACT ON THE ENVIRONMENT

The paper describes a construction impact on the environment, people and their health, taking into account its subsequence. The authors offer an optimal way of building construction in order to satisfy the environmental control standards and impact on the environment. There are a few criteria of ecological materials compared with conventional materials. The aim of this investigation is to develop approach of building project ranking. The paper deals with analysis of the construction alternatives of one‐flat dwelling houses. A few alternatives are given about how to choose an optimal project. The impact of construction on the environment is discussed. Analysis is performed taking into account building life‐cycle impact on the environment, its financial and social conditions. The investigation includes pollution of building material production, construction processes, taking into account building longevity, price, running cost and utilization input of energy. Multicriteria assessment of the alternatives is made, considering impact not only on humans, but also on the environment. According to the described environmental, financial and qualitative criteria and by the assistance of newly‐developed multicriteria method SAW‐G, it was calculated, that a blockhouse, made mostly of wood‐based materials with the result of 0.303 is by 6.6% a better alternative than a wood‐frame building with the result of 0.286, made from wood‐based and mineral‐based materials, and the worst result of 0.280 was in a building from traditional bricks (a wood‐based house is by 7.5% better than a brick house). AHP approach and SAW‐G method are useful tools to help support a decision in convention site selection. Santrauka Aprašomas statybos darbu padariniu poveikis aplinkai, žmonems ir ju sveikatai. Autoriai siūlo optimalu varianta iš pateiktu statybos projektu, atitinkančiu aplinkos apsaugos reikalavimus. Pateikti ekologišku statybiniu medžiagu kriterijai, palyginti su tradiciniu medžiagu kriterijais. Šio tyrimo tikslas yra sukurti statybos proceso klasifikavimo eile, atsižvelgiant i ekonominius ir aplinkos apsaugos aspektus. Nagrinejamos vienbučio gyvenamojo namo statybos alternatyvos. Pateiktos kelios alternatyvos, kaip parinkti optimalu projekto varianta. Aptartas gamybos darbu ir statybos poveikis aplinkai. Analize atliekama atsižvelgiant i statybos gyvavimo ciklo poveiki aplinkai, finansines bei socialines aplinkybes. Tyrimas apima tarša statybiniu medžiagu gamybos procese bei vykstant statybos procesui. Vertinama pastato ilgaamžiškumas, kaina, eksploatavimo išlaidos bei utilizacijos procesui suvartojama energija. Atliktas šiu alternatyvu daugiakriterinis ivertinimas, apibrežiant ju nauda ne tik žmonems, bet ir aplinkai. Remiantis straipsnyje aprašytais aplinkos apsaugos, finansiniais ir kokybiniais kriterijais, nauju daugiakriteriniu SAW‐G metodu buvo apskaičiuota, kad blokinis namas, pastatytas naudojant daugiausia medienos medžiagas (rezultatas 0,303), yra 6,6 % geresnis už nama (rezultatas 0,2860), pastatyta iš medinio karkaso ir naudojant mineralines bei medienos medžiagas, o blogiausias rezultatas ‐ tai namas iš tradicinio plytu mūro (rezultatas 0,280) (medinis namas yra 7,5 % geresnis už mūrini). AHP ir SAW‐G metodai yra tinkami tokiems uždaviniams spresti. Резюме Описано влияние последствий строительства на окружающую среду, человека и его здоровье. Из приведенных строительных проектов, соответствующих экологическим стандартам, авторами статьи выбран оптимальный вариант. Приведены критерии экологичных строительных материалов и сравнены с традиционными материалами. Целью настоящего исследования было разработать очередность классификации строительного процесса с учетом экономических и экологических аспектов. Проанализированы альтернативы строительства одноквартирного жилого дома с целью выбора оптимального проекта. Обсуждено влияние строительства на окружающую среду. Анализ проведен с учетом воздействия жизненного цикла здания на окружающую среду, а также финансовых и социальных аспектов. Исследовалось загрязнение от производства строительных материалов, от процесса строительства с учетом долголетия дома, цены, расходов на эксплуатацию, а также энергии, расходуемой при утилизации. Произведен многокритериальный анализ вышеупомянутых альтернатив, оценена польза, приносимая как человеку, так и окружающей среде. На основании критериев охраны окружающей среды, финансов и качества работ с помощью нового многокритериального метода SAW-G было установлено, что блочный дом, построенный из деревянных материалов с результатом 0,303, на 6.6% лучше, чем дом из деревянного каркаса с минеральными и деревянными материалами с результатом 0,286. Наихудшим вариантом оказался дом, построенный из традиционной кирпичной кладки с результатом 0,280 (деревянный дом лучше кирпичного на 7,5%). Для решения задач такого типа оказались приемлемыми методы AHP и SAW-G.
