The great challenge of propeller cavitation in shipbuilding. Continuous control with the innovative Non-Intrusive Cavitation Detection System (Ni-CDS)
Authors: Beltrán Palomo Publio , García Méndez Richard , Piqueras Luis Antonio 
Published: July 2023

Cavitation is an unwanted phenomenon that has been present for more than 50 years in any ship propulsion system. Despite the great technological advances with the use of advanced simulation tools (CFD's), and new technology, we are still far from being able to eliminate it from propellers due to its own operating principle. This phenomenon will continue to occur under certain conditions of operation of the propulsion system of ships.
The consequences of this phenomenon are well known to the Navies, shipowners and naval engineers: reduction of the service life of the propeller and sometimes of the rudder and hull too, reduction of propulsive efficiency, a significant increase in vibrations and noise on board and, consequently, a reduction in comfort conditions and stealth capacity, together with noise pollution with negative effects on the oceans and marine fauna. This issue has been on the table at the IMO since 2008, currently working on updating MEPC.1/Circ.833. For this purpose, a working group of more than 120 experts from 40 entities (countries and organizations) from all over the world has been created, being TSI one of its most involved members.
After more than 5 years of research, TSI has developed the first non-intrusive system capable of automatically and continuously detect this phenomenon and quantify its intensity, with sufficient precision to provide valuable information for its control. By having a visible and real time indicator of this phenomenon, we can act and reduce the negative effects of cavitation and control the acoustic signature of our vessel at all times.

The objective of the work was to study the effectiveness of the use of purified bacterial lysates of the most therapy-resistant strains of microorganisms, the causative agents of pustular skin infections, by comparing clinical data and the skin microbiome in patients with acne. The results of the study are based on the data of a comprehensive examination of 35 patients with acne of 2-3 degrees before and after treatment, as well as data of the examination of 15 patients of the control group. Examination methods: clinical examination of the skin, determination of the quantitative composition and microbiological identification of the skin microbiome (bacteria of the genera Staphylococcus, Streptococcus, Propionibacterium Corynebacterium, Micrococcus, Sarcina, Aerococcus, Acinetobacter, Brevibacterium, Citrobacter, Serratia, Lactobacillus; yeast-like fungi of the genera Malassesia and Candida, mold fungi ). In the studied patients with acne, the representative microorganisms of the skin microbiome were Propionibacterium acnes, S. epidermidis, and C. lipophilicum. In patients with acne, the stability of the skin microbiome was carried out due to the redistribution between S. epidermidis and C. lipophilicum. In patients receiving "Acnevac"® (Bioveta, a. s.), a component of a complex treatment, along with earlier periods of clinical improvement, there was noted an earlier normalization of the skin microbiome in comparison with patients receiving standard therapy. Approaches to the treatment of acne with antibiotics and chemotherapy require a revision. The state of the skin microbiome broadens knowledge on the pathogenesis of acne and the search for other means for the individual treatment of patients. Positive changes in the skin microbiome under the influence of treatment with purified bacterial lysates of the most therapy-resistant strains of microorganisms, the causative agents of pustular skin infections, make it possible to recommend its use for a longer term – up to 6 months.

The formation of human health takes place under conditions of both positive and negative influence of the external environment. There is an undoubted connection between human health and the degree of its intervention in the natural environment, which, in turn, is determined by the level of environmental awareness of society. The purpose of this study was to determine the relationship between the levels of awareness, instructions and activities at different levels of environmental consciousness of modern youth. Used methods: bibliographic; questionnaire method (to collect data on the environmental awareness of young people); statistical (for selection and analysis of obtained data); mathematical (for constructing formulas and calculating levels of ecological consciousness and its components). A questionnaire was developed to survey students and high school students in different cities of Ukraine. 285 respondents aged 15 to 24 took part in the survey. In order to compare the level of environmental awareness of young people with people of other age groups, 53 respondents over the age of 24 were involved in the survey, which was 15,7% of the total number of respondents. The questionnaire was conventionally divided into semantic modules for the possibility of determining the levels of environmental knowledge, instructions and behavior. To achieve the goal of the work, the level of environmental awareness and its components, taking into account gender and age, was assessed. Quantitative values of the levels of the components of environmental consciousness were calculated according to the integral evaluation formulas. For the convenience of assessing the level of the components of environmental consciousness, the quantitative values were ranked in three classes: "weak", "medium" and "high" severity. It was found that young people of both sexes almost do not differ in the high level of guidance. However, the share of girls with a high level of awareness is slightly higher than the share of boys and is significantly higher by a high level of activity. Awareness of the social and individual value of nature increases significantly with age, but readiness for active nature conservation activities does not change with age. The dependence of eco-awareness on the place of residence has been established: in small towns, the eco-awareness of residents is higher than in those who live in large cities. Also, eco-awareness depends on the field of study: students of humanitarian specialties have a significantly higher level of eco-awareness than students of technical universities. The analysis of the obtained results will contribute to the development of ways of forming the ecological consciousness of pupils and students, which is one of the main tasks of ecological and hygienic education and education of young people.

Cultural Tourism and Knowledge Management:
The Importance of Epistemological Awareness in Cultural Tourism Destination Management
Authors: Marhomi Cakra Ludra 
Published: July 2023

<p class="Abstract">Tourism is an industrial sector that is proliferating and
promises benefits to large groups of people. This growth encourages the
formation of tourist destinations consisting of infrastructure, supporting
communities, and tourist attractions in many places. Some tourist destinations
highlight the culture of the people as part of a tourist attraction. Using
local culture as a tourist attraction will inevitably lead to a shift in the
values and meanings of the culture. Culture consists of three dimensions;
artifacts, behaviors, and ideas. Dimensions of ideas from culture include,
among others, beliefs and knowledge that are owned and passed down from
generation to generation through formal and non-formal education processes. In
the context of culture as a tourist attraction, the dimensions of local
cultural ideas will adapt to the tourism paradigm. Local beliefs will become a
part of an economic system that emphasizes uniqueness in its interactions with
other beliefs. Local knowledge, which includes factual, conceptual, procedural,
and metacognitive knowledge, initially a process of adaptation of local
communities to their environment, is now part of the tourism paradigm. Because
of its global nature, the tourism paradigm is a paradigm that has universal
standards. Therefore, epistemological awareness is needed to meet the
dimensions of local cultural ideas and the global tourism paradigm. This
epistemological awareness can be stimulated through knowledge management of the
supporting community in the tourist destination by utilizing existing
educational institutions and local organizations.<b><o:p></o:p></b></p>
The Epistemic Status of Indigenous Knowledge: A Socio-epistemological Approach
Authors: Hukmi Risalatul , Khair M. Rodinal 
Published: July 2023

<p class="Abstract"><span lang="EN-ID">The notion
of indigenous knowledge has mostly been constructed based on the assumption
that knowledge is actually intertwined with any certain socio-cultural
condition. In that assumption, the social somehow is considered determining how
knowledge is produced and obtained in any society. In other words, the
tenability of knowledge is not measured merely by individual reasoning but
through the question of how some beliefs can be justified by social context.
Hence, the main objective of this paper is to argue that indigenous knowledge
is as valid as scientific knowledge with some conditions, that is its openness
to be falsified. Therefore, the paper argues that the separation between
indigenous knowledge and scientific knowledge is irrelevant.<o:p></o:p></span></p>
