KELUHAN PENDENGARAN DAN PEMETAAN KEBISINGAN PADA INDUSTRI PENGGERGAJIAN KAYU UD. MAYOA KABUPATEN JEMBER
Authors: Indrayani Reny , Aryatika Karera
Published: December 2021

Keluhan pendengaran, menurut banyak penelitian telah dinyatakan berkorelasi positif dengan kehilangan pendengaran. Kehilangan pendengaran merupakan penyebab kecacatan keempat tertinggi di dunia dan dapat disebabkan oleh paparan kebisingan di tempat kerja. Banyak penelitian mengungkapkan bahwa salah satu sektor pekerjaan dengan tingkat kebisingan tinggi di area kerjanya adalah pengolahan kayu. WHO merekomendasikan adanya tindakan identifikasi gangguan pendengaran beserta penyebabnya, dan menerapkan tindakan pencegahan untuk membatasi dampak merugikan yang ditimbulkan oleh paparan kebisingan. Tujuan dari penelitian ini adalah untuk menggambarkan keluhan pendengaran yang dialami pekerja dan memetakan intensitas kebisingan di tempat kerja industri penggergajian kayu UD. Mayoa Jember guna menentukan jenis alat pelindung telingan / pendengaran yang dibutuhkan oleh pekerja. Penelitian ini merupakan penelitian deskriptif. Data yang digunakan dalam penelitian ini merupakan data primer yang didapatkan melalui wawancara dan observasi. Wawancara dilakukan kepada seluruh pekerja yang berjumlah 32 orang. Observasi dilakukan dengan melakukan pengukuran intensitas kebisingan pada 139 titik pengukuran yang tersebar di seluruh area kerja. Pengolahan data untuk pembuatan peta sebaran kebisingan dilakukan dengan bantuan aplikasi Surfer ver.16. Hasil penelitian menunjukkan bahwa sebagian besar responden mengalami keluhan pendengaran pada level yang tidak mengganggu aktifitas. Pemetaan intensitas kebisingan menunjukkan bahwa kebisingan yang terjadi pada saat jam kerja berkisar antara 73,8 – 105,2 dBA dan luas area dengan tingkat kebisingan di atas NAB adalah sekitar 500 m2. Intensitas pada saat jam istirahat berkisar antara 68,2 – 101,0 dBA dengan luas area dengan tingkat kebisingan di atas NAB adalah kurang dari 30 m2. APT yang direkomendasikan untuk tingkat kebisingan 86 - 95 dBA adalah sumbat telinga, untuk kebisingan 96 – 100 dBA adalah sumbat telinga/penutup telinga, sedangkan untuk kebisingan lebih dari 100 dBA adalah perlindungan ganda yakni sumbat telinga dan penutup telinga. Saran yang dapat diberikan kepada pengurus usaha adalah untuk melakuan redesain jam kerja atau melakukan rotasi kerja.

Kapitasi berbasis pemenuhan komitmen pelayanan (KBKP) merupakan salah satu sistem pembayaran dalam program jaminan kesehatan nasional pada puskesmas untuk meningkatkan pelayanan yang efektif dan efisien sehingga mutu layanan yang diberikan dapat terjaga. Kabupaten Jember sebagai salah satu kabupaten yang menjalankan kebijakan tersebut, namun diketahui terdapat kendala dalam pelaksanaan kebijakan tersebut. Penilaian terhadap puskesmas melalui KBKP dilihat berdasarkan pencapaian indikator yang meliputi angka contact rate, rasio rujukan rawat jalan non spesialistik, rasio peserta prolanis dan 1 indikator tambahan yaitu kunjungan rumah. Namun pelaksanaan kebijakan ini terdapat beberapa permasalahan yang dapat menghambat pencapaian target. Penelitian ini menggunakan metode Riset Implementasi. Riset ini membahas berbagai masalah implementasi dalam konteks yang beragam dimana pengambilan datanya dilakukan secara kualitatif (indepth interview) dan kuantitatif (analisis data sekunder). Evaluasi pelaksanaan KBKP tahun 2016 menunjukkan masih banyaknya tantangan dan hambatan sehingga BPJS Kesehatan mengeluarkan petunjuk teknis terkait KBKP. Tujuan penyusunan petunjuk teknis tersebut adalah memberikan panduan bersama pelaksanaan pembayaran kapitasi berbasis pemenuhan komitmen pelayanan di FKTP. Pemerintah daerah diketahui kurang terlibat dalam kebijakan KBKP tersebut, tidak terdapat kebijakan yang mendukung kebijakan KBKP di tingkat kabupaten. Pencapaian target indikator yang telah ditetapkan dalam regulasi KBKP masih sulit dicapai oleh puskesmas khususnya pada indikator contact rate, pencapaian target indicator contact rate hanya 15 puskesmas (30%). Pencapaian indikator rujukan non spesialistik yang telah ditetapkan dalam regulasi KBKP selalu dapat dicapai oleh puskesmas (100%), namun indikator prolanis target pencapaiannya hanya 38 puskesmas dari 50 puskesmas yang dapat mencapai (76%). Sulitnya pencapaian target indikator contact rate karena petugas kesehatan di puskesmas tidak sempat meng-entry data kontak sehat dan kontak sakit pada aplikasi P Care. Diketahui KBKP dapat meningkatkan kepuasan peserta karena memaksa puskesmas untuk meningkatkan contact rate dengan peserta JKN dan merasa di ‘spesial’kan dengan program prolanis. Kebijakan KBKP juga dapat meningkatkan mutu pelayanan puskesmas karena puskesmas harus meningkatkan sarana prasarana agar 145 diagnosis tersebut dapat diselesaikan.

Świadczenia dla działaczy opozycji antykomunistycznej i osób represjonowanych z powodów politycznych
Authors: Stopka Karolina
Published: December 2021

The purpose of the study is to present the benefits for anti-communist opposition activists and persons repressed because of anti-communist activity normalized in the Act of 20 March 2015 on anti-communist opposition activists and persons repressed for political reasons. The regulation is a relatively new manifestation of the state’s historical and social policy in the field of social security of citizens fighting for the sovereignty and independence of the homeland, not discussed in much detail in the literature.

As part of the introductory remarks, the paper points out the place of benefits for “oppositionists” in the social security system, their constitutional conditions, as well as the motives and goals that guided the legislator while passing the law. In the further part of the study, the subject and object scope of these benefits were indicated, particularly the criteria based on which notions of anti-communist opposition activist and person repressed for political reasons were defined. It was stressed that some manifestations of “opposition” activity are at the same time elements defining other categories of persons involved in the fight for sovereignty and independence of the homeland and that personal injury (its concrete form), as a rule, is not a constructional element of these concepts. Due to the limited scope of the study, only the legal regulation of financial benefits for “oppositionists” was analyzed in more detail. The description takes into account changes in the legal regulation of their catalog and the conditions of their use. The article assesses the adequacy of the adopted legal solutions to the assumed objectives of the benefits and comments formulated in the analysis of the concept of anti-communist opposition activist and person repressed for political reasons.

The analysis leads to the conclusion that in the current legal state, the benefits for “oppositionists” are an expression of the legislator’s aspiration to exclude them from the group of social assistance recipients and to guarantee them support taking into account their merits for Poland. This support is a form of specific — “tailored to meet the needs of social security and the financial capabilities of the state” — partial compensation of damages, including those caused by the opposition, as well as non-material damage, even though its specific forms do not directly determine the subjective and objective prerequisites for determining the right to benefits. However, the omission of the family members of a deceased “oppositionist” from the group of entities entitled to benefits was regarded as dubious.
Food crisis in fast-growing Turkmenistan
Authors: Nowak Wioletta
Published: December 2021

Since the beginning of the 21st century, Turkmenistan’s economy has been growing very fast, which has been primarily generated through the extractive sector and construction industry. After the energy price collapse in mid-2014, the country has recorded a shortage of foreign currency. The authoritarian regime passed currency and economic problems onto the society. As a result, the country has experienced the most severe food crisis in its history.

The main aim of the paper is to identify the reasons behind the food crisis in Turkmenistan. The paper tries to answer the following question: how did it happen that people in one of the fastest-growing countries in the 21st century have been suffering from food shortages? The study is based on data retrieved from the World Bank Open Data, ILOSTAT, and Observatory of Economic Complexity, as well as a critical review of independent news websites.

The food crisis in Turkmenistan was primarily caused by hyperinflation and rationing basic groceries at preferential prices, wage arrears, cutting salaries of state employees to fund construction projects in progress, group layoffs of state employees, growing difficulties in running a private business, and depriving people of the possibility to exchange the currency at the official rate. The end of a free provision of Turkmenistan’s population with electricity, gas, and drinking water has further deepened the crisis.

Problem z aktywnym poszukiwaniem w internecie treści o charakterze terrorystycznym. Uwagi na tle unijnego rozporządzenia
Authors: Galewska Ewa
Published: December 2021

The new EU regulation is aimed at fighting terroristic content online. Of particular importance are its provisions on special measures and assessment thereof in the light of the directive’s provisions on hosting providers’ liability for online content. EC’s radical proposals in this respect raised serious doubts in the legislation procedure. The European Parliament and the Council intended to ensure the compliance of a regulation blueprint with the directive 2000/31/WE, therefore they proposed a variety of amendments to provisions on special measures. It is, however, doubtful that these guarantee a full coherence with the regime of hosting providers’ liability. In order to tackle terroristic content effectively, it is necessary to transform the existing regime of hosting providers’ liability that was established in the directive almost 20 years ago and does not respond to problems that we currently face.
Podatek od zysków wojennych w polskim systemie danin jako źródło finansowania kosztów wojny polsko-bolszewickiej
Authors: Antonów Dobrosława
Published: December 2021

The paper draws attention to one of the emergency taxes in the history of the Polish Treasury, i.e. a tax on war profits. It was levied under the Decree of 5 February 1919 on the Establishment of a Tax on War Profits. This levy introduced a concept which was developed in Europe and built on the First World War experience. In the reborn Poland, the tax was supposed to have two functions: fiscal — as a source of financing the extraordinary expenditure arising from the war against the Soviets and a social function — as an additional burden on those taxpayers who were able to accumulate wealth and earn substantial profits as a result of the First World War.

Badania nad totalitaryzmem — prawda historyczna i wolność indywidualna — prawo prywatne w służbie publicznej. Uwagi na tle „cywilnoprawnych” przepisów ustawy o IPN
Authors: Machnikowski Piotr
Published: December 2021

The much-publicised and rather unfortunate amendment of 2018 to the Act on the Institute of National Remembrance introduced not only the controversial and subsequently repealed penal provisions, but also the provisions on “Protection of the good name of the Republic of Poland and the Polish Nation”. According to these, protecting the good name of the Republic of Poland and the Polish Nation is subject to the provisions of the Civil Code. The intention of the lawmakers was to prevent the dissemination in public discourse of the false expression “Polish death camps” and similar expressions sometimes used to refer to Nazi German extermination camps located in the occupied territory of Poland. The provision mandating the application of the provisions of the Civil Code on personal rights to the protection of the state and nation’s good name may serve the intended purpose. However, its application may also be much broader, due to the vagueness of the wording used (“good name of the state and nation”) and the powerful protection afforded to personal rights in the Civil Code.

The author discusses which provisions of the Civil Code can and which cannot be applied in this case. He also draws attention to the inadequacy of private law tools to protect public interests. He calls for a restrictive interpretation of the provision and recognizing a wide range of circumstances excluding the unlawfulness of an infringement in order to protect constitutional values such as freedom of expression, artistic creation, or scientific research.
Infographic: Fifteen years of Brazilian Journal of Motor Behavior
Authors: Barbieri Fabio A. , Barela José A. , Rinaldi Natália M.
Published: December 2021

The Brazilian Journal of Motor Behavior (BJMB) is a quadriannual, peer-reviewed, free of charge/fee and open-access journal published by the Brazilian Society of Motor Behavior (SOCIBRACOM). The BJMB has published original contributions within the multidisciplinary study of human motor behavior, in the broad scope of motor control, development and learning, movement disorders, sports, clinical, theoretical and model studies. Since 2019 the BJMBpublishes manuscripts only in English. In the same year, BJMB started to invite researchers to be guest editors in article collections, providing an excellent opportunity to promote high-quality contents within the field.

The BJMB is the main motor behavior journal in the Latin American. It is widely recognized for its significant academic contribution and indexed in the UlrichsWeb Global Serial Directory, Diadorium, Gale Directory Library, Google Scholar, Road Directory of Open Access Scholary resources and Red Iberoamericana de Innovación y Conocimiento Científico. The number of edition and papers has sustainable and significantly increased in the last years, with over 500 authors contributing with 121 manuscripts, distributed in 40 numbers. The time of peer-reviewed process is short (first revision- 26 days) and paper publication is quick (57 days).

The BJMB was launched with its first edition published in December of 2006 and, thus, we are celebrating its 15thanniversary. For that, the BJMB launches a new type of manuscript: INFOGRAPHIC. This initiative aims to provide a quick, easy-to-use and enjoyable publication that conveys notable knowledge. Two types of infographics will be publishable: a) theory perspective: visual material to theory acknowledge to facilitate the understanding of models, theory frameworks, concepts, principles, and approaches in the field; b) article infographic: visual material about interventional effects on motor learning, development and control sustained by reviews and/or meta-analysis.

The infographic section will be added to those already existing: research, systematic review and meta-analysis, mini review, scoping review, research notes, current opinion, critique, and tutorials. It is interesting to highlight the section about tutorial, which emphasizes and provides reflection on the use of one or several methods or self-instruction in motor behavior. Finally, the current opinion section publishes pieces of diverse authors around the world that provide perspectives on a hot, relevant, and perhaps controversial topic within the scope of BJMB.

We would like to congratulate all for this important occasion and to wish that the BJMB continues publishing impactful and relevant contributions in the motor behavior field still for many years to come.

CONTINUOUS FREQUENCY METER FOR A REACTION WHEEL
Authors: Ю. М. Маринич  , Ю. М. Гуменюк  , Ф. О. Іваха
Published: December 2021

The usage of reaction wheels as executive parts for control systems of angular orientation and stabilization of spacecraft remains the most widespread method of angular control for a satellite. To create highly effective control system rigid demands are pulled out for reaction wheels such as mass-size characteristic, proportionality of reaction momentum to control signal and minimization power losses during energy transformation.The biggest errors in recreation of control law of reaction wheels take place during rotor angular velocity sign change, as in this moment compensation systems do not decrease but increase the influence of back EMF and friction momentum until the moment the information about angular velocity is renovated. When the angular velocity crosses the null pulsation of reaction momentum takes place. This problem is more important for reaction wheels of micro- and nano- level, as their small size limits the number of poles of the magnetic system and thus the number of information renovation points is small.The article is dedicated to the method of formation of quasi-stationary  signal of  rotor rpm of compact reaction-wheel, built on the basis of 2-and 4-pole three-phase brushless DC motors. The proposed approach allows the use of rotor position sensor signals to form a signal of rotor rpm of reaction-wheel and eliminate the error of reproduction of control law for reaction-wheel when the sign of the angular velocity of rotation of the rotor changes.

Published: December 2021

This paper considers the methodology of modular combinatorial-variational geometric modeling for technical objects on the example of automated shaping of some typical airplane structural elements.Stringers, beams, frames, spars, etc. were analyzed. Parametric geometric models of these objects were built. The models were combined with structural and parametric tools for effective computer-aided design.The proposed modular approach allows you to improve the performance of the creation processes of complex equipment. These simulation tools can successfully implement a comprehensive optimization of industrial products throughout their life cycle.It is possible to integrate computer structural-parametric geometric models stringers, beams, frames, spars, ribs, etc. with their design, technological and operational models in computer-aided design.The proposed approach is illustrated by computer model created in the environment of the software package SolidWorks. The curves of the second order in the rational parametric form were used for this purpose. Based on them, structurally-parametric solid models of the elements of the aircraft structure were built. Kinematic shaping techniques have been widely used in solving these tasks.Summary of the application of elaborated design techniques in other CAD/CAM/CAE systems to develop such parts and components of aircraft has been made.This applied research area automation design of complex modern techniques has good prospects for further development. However, it needs to carry out further intensive research of such sciences as geometry, design of aircraft, its aerodynamics and strength, manufacturing technology and exploitation to integrate successfully by means of computer information technologies.
DEFINITION THE STABILITY AND CONTROL DERIVATIVES IN THE LONGITUDINAL CHANNEL OF SMALL SUBSONIC UAV
Authors: О. В. Збруцький  , Р. В. Карнаушенко  , О. П. Мариношенко
Published: December 2021

The problems of determining the stability and control derivatives of small subsonic UAV in the longitudinal channel are solved.An approach to the stability and control derivatives determination based on the analysis results of wind tunnel investigation and analyzes conducted .To the longitudinal movement usually referred traffic aircraft where it is in the plane of symmetry of one and the same vertical plane. Thus the aerodynamic lateral force, rolling moment and yaw angles of heel and slip and angular velocity of roll and glide zero. To investigate the longitudinal motion of the aircraft (movement in the longitudinal channel) important issue is to determine the components of the aerodynamic forces and moments as a function of the kinematic parameters of the flight, the so-called aerodynamic derivatives.Given that the object is a lightweight UAV that has subsonic range of operating speeds, significantly less than the speed of sound, it should be noted that the derivative of the coefficient of lift coefficient and drag coefficient for longitudinal moment of flight speed can be taken to be zero at subsonic speed range. This is due to the fact that these values are almost constant with airspeed , lower the speed of sound . Change the value of these parameters with growth rate appears only when approaching the speed of sound, due to changes in the position of the center of pressure and the additional impedance. Also, when calculating stability derivatives are generally neglected by changing the drag because the drag value of derivatives are small and commensurate with the error of the calculation methods.Derivatives of lift coefficient by the following kinematic parameters: angle of attack, the angular velocity of rotation around the transverse axis , rate of change of angle of attack and angle of elevator deflection are defined.Obtained results make it possible to analyze the movement of the UAV in the longitudinal channel and determinate the coefficients of a mathematical model of the UAV. Also possible  to determinate the stability and controllability of the UAV during automatic control systems design.

When this converter is excited at a resonant frequency.Analyzing the experimental and theoretical results, it should be noted that the formulation of the problem was carried out in an analytical form. Formulation and solution of the problem allow us to find the physical characteristics of the studied transition.Based on a comparison of experimental and theoretical work in the conclusion of the applicability of the results in practice, the proposed mathematical models of cylindrical piezoelectric transducers (thin electroelastic bodies), based on the linear theory of electrodynamics and of the Kirchhoff – Love in the time-dependent problems in calculating hydro acoustic transducers.Experimental studies were carried out for commercially available cylindrical transducer brand TSTBS – 3 is in the liquid, and the considered regimes of pulsed electrical excitation are working for most of sonar systems. Tests have shown that the actual design features of the considered cylindrical transducer little effect on the configuration of the acoustic pulses of radiation in different directions. Applied mathematical models of thin electroelastic bodies are recommended for use in the design practice in the design of sonar technology for various purposes.The study of the transition process is relevant for the decision of problems like these.
ON STRESSES CAUSED BY RAYLEIGH WAVES IN THE IMPACT OF ELASTIC BODIES
Authors: Д. І. Ільчишина
Published: December 2021

We have investigated the stress field in the contact area of the colliding bodies in the presence of influence arising from the impact of Rayleigh waves.The stress field in the bodies is seen as the result of superposition of the two fields. The first field – the field of contact stresses associated with the contact conditions. The second field is formed only by surface waves.Contact stresses are determined on the basis of the theory of the Newtonian potential. Stresses caused by surface waves are determined on the basis of the resolution of Lame equations.A specific example is considered. The predominant influence of the Rayleigh waves caused by a blow on the magnitude of the stresses in the colliding bodies is shown.
WAY OF FORECASTING OF WEIGHT OF A WING OF THE PLANE OF A TRANSPORT CATEGORY IN THE CONDITIONS OF DESIGN UNCERTAINTY
Authors: Юрій Іванович Бондар  , Віталій Віталійович Сухов
Published: December 2021

Identify the relationship between the aerodynamic loads , weight of the wing structure and its deformations is an important issue in the early stages of the design of transport category aircraft.Existing methods of the weight analysis allow to estimate weight of basic elements of the plane (a wing, a fuselage, plumage, the chassis, wing mechanisation), but forecasting of distribution of these weights along their basic axes is a special problem.The work purpose is working out of a way of forecasting of running weight of a design and fuel distribution on tanks on a wing of the plane of a transport category at stages of outline designing.When determining the load of the weight of the wing structure input data are concentrated and distributed weight values that are determined by special methods of calculation. Insufficient accuracy of distribution of mass loadings can lead to unreasonable surpluses or lacks of durability of a design. Overestimate of weight of a design of a wing increases effect of unloading from own weight that reduces size of settlement weight. Understatement of the wing reduces weight and unloading heavier its design. Using regression analysis methods for processing of statistical data on the aircraft weight peers increases the accuracy of calculations.
DATA FILTERING METHODS FOR HYDROGRAPHIC SURVEY DATA
Authors: Павло Б. Олійник
Published: December 2021

Current trends in navigation are characterized by the further increase of demands on the precision of hydrographic information, especially of the nautical maps. Thus, precision of both spatial position and depth bathymetric data is important for ensuring safe navigation, and so problem of data filtering and elimination of outliers arises.In the present work, comparison of methods, used for postprocessing of depth data, measured by echosounder, is done.First of all, review of commonly used data filtering and outlier elimination methods is done, and their advantages and disadvantages are analyzed.As improved outlier elimination algorithm and median filtering has their flaws, Kalman filtering is considered as a measure of outlier elimination and real data estimation. It’s shown that Kalman filter can both effectively filter noise and eliminate outliers; however, quality of the filtered data strongly depends on measurement noise covariation and process noise covariation estimates,  and  respectively. At that, the lower  is, the better noise is filtered and the smoother depth profile is; the higher  is, the better outliers are eliminated. However, care must be taken, as depth profile is distorted at high  values, and noise is almost not filtered at low ones.It’s shown that noise covariation estimate has more influence on data filtering; therefore, one should pay attention to correct  estimation. For practical reasons, values of ; =10 are recommended.In the recent works, wavelet filtering is considered as a promising method of data filtering in postprocessing. Therefore, as a next step, comparison of Kalman filtering and wavelet filtering is done using the real-world data. To that end, white noise is added to filtered and smoothed data, and then those data are filtered by methods, mentioned above. Corellation of source and denoised data is chosen as a criterion of filter effectiveness.It’s shown that Kalman filter is somewhat less effective in data postprocessing than wavelet filter. However, as Kalman filter allows one both to filter noises form the measured data and to eliminate outliers, and can be used for “on-the-fly” data filtering, it’s advisable to use Kalman filtering for real-time measurements during surveys, and wavelets for data postprocessing.Future studies may be devoted to improvement of existing and introduction of new data filtering and postrprocessing methods.

Axial accelerometers with a planar silicon suspension and capacitive sensor for inertial mass displacement are one of the most promising navigational sensors at the present time. On the other hand improvement of the precision characteristics remains a primary problem to be investigated for micromechanical sensors.The main requirement for this type of sensors is the constancy of the operating compliance throughout the whole metrical range of the accelerometer. Furthermore, the operating compliance has to be small enough to allow the measurement of the upper limit of acceleration.In the present work we provide the detailed design features analysis for the direct action planar accelerometers.We also show stiffness characteristics of an elastic suspension inside the aforementioned accelerometer and determine the degree of characteristics variation by the displacement of its inertial mass.Further, we investigate the nature of nonlinearity of the scale factor in the direct action axial micromechanical accelerometers and characterize the conditions of its appearance.As a result we propose modifications to the structure of the elastic suspension in the accelerometer for significant reduction of the nonlinearity of its scale factor.

CHALLENGES AND BENEFITS OF EXPERIENTIAL LEARNING: THE CASE OF OVERSEAS EXCHANGE PROGRAMS
Authors: Yang Chieh Yun , Xie Dengming , Wong Jose Weng Chou
Published: December 2021

This article highlights an increasingly popular form of experiential learning, namely overseas exchange programs. Experiential learning is regarded as a valuable way to link up theoretical knowledge and practical skills in hospitality and tourism education. Although some studies have addressed the importance of experiential learning, the factors influencing students’ choice of overseas exchange programs, and the challenges and benefits of students’ experiential learning are still unclear, especially on the overseas exchange programs. The purpose of this study is to reveal the whole picture of overseas exchange programs by utilizing experiential learning cycle theory, and further understand students’ perception of overseas experiential learning. By employing quantitative and qualitative methods, including questionnaire survey and in-depth interviews with students who have participated in the overseas exchange programs and content analysis of program information, this study analyzes the differences of factors considered by males and females in choosing overseas exchange programs, and displays the four-stage learning process of experiential learning in overseas exchange programs and identifies two themes of challenges (living challenges and learning challenges) and five themes of benefits (cognitive development, behavioural change, multiple skill development, social bonding development, academic competitiveness & employability enhancement) for experiential learning for students majoring in Hospitality and Tourism. The study enriches our understandings of the experiential learning cycle theory and provides insights to educators in the design of future overseas exchange programs.

This paper aimed to explore the variables that influenced the intention to quit the teaching profession among vocational teachers. Moreover, the researchers examined the differences in the perception of the levels of emotional exhaustion, depersonalization, personal accomplishment, job satisfaction, and life satisfaction among vocational teachers in Thailand. The target population comprised vocational teachers from public colleges in Thailand with a total number of 29,915. The stratified random sampling technique was used for selecting the samples. The data collection involved self-report surveys from 510 vocational teachers from 55 vocational colleges in Thailand's metropolitan, north, northeast, east, and south. Correlation and regression analyses were used to examine the possible relationships among the variables and identify the significant variables. The findings reported that emotional exhaustion and depersonalization were moderate while personal accomplishment was at a high level. Job satisfaction was the strongest predictor of the intention to quit. In addition, three components of burnout influenced the intention to quit among the vocational teachers: emotional exhaustion, depersonalization, and personal accomplishment. For the implication, this study recommended a practical application in the dimension of policy improvement concerning teachers' welfare. It emphasized the need to develop programs supporting teachers' mental health to reduce burnout and increase job satisfaction.

The pandemic situation in Slovakia has shown that e-learning teaching within educational institutions has not received sufficient attention so far. The purpose of the paper is to stress the importance of e-learning application in foreign language teaching as well as show the possibilities of creating new educational portals for university students using professional foreign language texts. The KEGA project “Innovative Methods and Forms of Education for Needs and Development of Language and Communication Skills within Technical Professional Foreign Language Study Material” is still ongoing at the Department of Social Sciences and Humanities. The aim is to emphasize the importance of foreign language training for future engineers, and at the same time to look for modern and innovative mixed methods of education, which includes the use of e-learning. The paper compares the study results of more than 200 students in different study programmes at the Faculty of Manufacturing Technologies in Prešov Technical University of Košice achieved during the academic year 2020/2021. The research findings prove that the experimental group of students from different study programmes achieved the best study results in those manufacturing technologies e-tests which are closely connected with their study programme. The results confirm that English teaching focused on tailor-made professional texts and topics within the engineering levels of studies was effective. Teachers also identified the strengths and weaknesses of students within tasks to practice language competencies. By applying e-tests students were able to improve their language skills, which can be practised in selected foreign companies or in their future careers as engineers, technicians, managers or computer programmers.
