Abstract — Face recognition is a face-oriented recognition method by comparing patterns that have previously been stored in the database. In general, facial image recognition systems are divided into two types, namely feature based systems and image based systems. To carry out facial image recognition, there are several kinds of approach algorithms that can support the processing of the face image. One approach algorithm that is well known and capable of processing images with a good level of accuracy is the eigenface approach. By using the eigenface approach, the face image will be processed by performing a matrix calculation, which results in an eucludian distance to be able to get the suitability of the face image. so this research produces a result which includes: the results of the test on the FGD Functional says for the accepted percentage is: 73% for not accepted is 27%, for Non-Functional FGD says for the accepted percentage is 82% and not accepted is 18 %, and for the results of testing the adaptation of ISO 9126 in the good category with a percentage result of 79%, and the last test result, namely the Blackbox Testing test to be accepted is 83% and for the results the percentage that is not accepted is 17%

Published: May 2022

This paper demonstrates the use of augmented reality (AR) to teach the fundamental aspects of the human brain and guide proper EEG electrode placement. The proposed application consists of two main parts: (1) the proposed marker-based AR system uses the Vuforia technique to determine the dimension of the head to create the virtual brain and virtual EEG electrodes; and (2) user interaction and implementation. We performed two experiments using a phantom head to verify the size and workspace area of the marker and validated the position of the virtual electrode with ground truth data. The results showed that the proposed method can be employed for electrode placement guidance in the recommended range. We aim to use the proposed system for beginners. We will further test the system with human heads to evaluate the usability and determine key areas for application improvement.

Screen adaptation theory for humans
Authors: Lortie CJ
Published: May 2022

Screens are an ineliminable component of contemporary society for most humans. Consequently, tools and ideas that provide a heuristic and support for conceptually mitigating and balancing the costs of screen times at an individual level are critical. Here, screen adaptation theory (SAT) is proposed as a shorthand tool to frame the wealth of research examining human-screen interactions. Screens are best conceptualized as a place. Adaptation (to screens) are acquired or cultivated traits that enable us to not only survive with screens but potentially thrive—provided that we leverage research on costs and benefits. Adaptive behavioral traits suggest that we approach these interactions with purposeful intent. Finally, the theory associated with humans with screens is rich and interdisciplinary. We must design and adopt principles from theory relevant to our work, leisure, and individual choices to use screens as we move from tolerance to adaptation.
How do Firms Grow? Modes, Paths, and Strategies. A Review of the Literature
Authors: Vaz Rolando
Published: May 2022

How do firms grow? The objective of this research is to review and unify the literature that identifies Modes, Paths and Strategies available for firms to promote growth. The sample, selected from the Scopus, ScienceDirect and Google Scholar databases, comprises 115 works published between 1957 and 2021. This research offers three contributions to the firms' growth literature. Firstly, it unifies the literature on different modes of growth, into three main categories: organic, inorganic and hybrid. Secondly, it links these modes of growth with different strategic paths. Thirdly, it reviews the determinant strategies for firms’ growth and relates them to different modes of growth. We conclude that the literature on Modes, Paths and Strategies, both at the theoretical and empirical level, is far from being conclusive. Based on these insights, a new research agenda is proposed.

The Impact of Doula Support on Birth Roles, Infant and Maternal Health, and Pregnancy
Authors: Irons Meagan G. , Kunkel Kayla R. , Sandefur Eladio M. , Abraham Samuel P.
Published: May 2022

Background: Only 6% of birthing people in the United States use a doula during childbirth. Doulas are certified professionals skilled in providing continuous one-to-one support for the expectant mother by helping them achieve their birthing plan. In addition to regular nursing care, continuous one-to-one emotional support provided by support personnel such as doulas has shown promising outcomes for women in labor. However, the implementation of doulas remains controversial and is attributed to their underutilization. Purpose: The purpose of this review was to explore the impact of doula support on birth roles, infant and maternal health, and pregnancy. Method: A systematic analysis of this review includes evidence-based literature surrounding the impact of doula support. The patient, intervention, comparison, outcome, and time (PICOT) question guiding this review was: In labor and delivery, what are the effects of doulas on the pregnancy and laboring process vs. those without doula labor support throughout the pregnancy. Results: Themes of impactful doula support identified in this study included positive birth experiences, birth team dynamics, infant and maternal outcomes, and sociodemographic obligation. The findings of this study indicate significant evidence that doulas positively impact each of these themes. Conclusion: Doulas have an integral role within each of these by providing one-on-one care, continuous support, and possess extensive pregnancy and childbirth awareness that fosters a strong rapport with their clients. Promoting inclusive doula care among pregnant and postpartum women would allow doulas to further embody full-spectrum care to individuals. The benefits of doula use outweigh any potential burdens.

This study found that the conflict initially arose because of the centralization policy in the New Order era, which caused many forestry permits to be issued by the government without any discussion with the community. Then, the conflict intensified when the community lost a lot of economic resources that they used to get from forest resources. It is hoped that this conflict can be resolved soon so that the private sector and the community can get a win-win solution.

The article presents theoretical provisions and some practical recommendations for ensuring information security in Ukraine in the context of European integration. It was noted that today the strategic goal of Ukraine's foreign policy is national interests and European integration, where the implementation of the course towards integration into the European Union requires special measures, as well as the improvement of the legal framework for ensuring information security of Ukraine in accordance with international standards. It is also concluded that in order to ensure information security, Ukraine should actively cooperate with the member countries of the European Union and such cooperation should primarily consist in the formation and development of a regional and international information security system, the main focus of which should be aimed at prevention, countering and eliminating information threats that have already arisen, in particular, such as cybercrime and cyberterrorism. At the same time, it was established that ensuring the information security of Ukraine should be based on the standards of the European Union and NATO. It was determined that the prospects for further research in this direction are the study of the features of training specialists in the field of information security of Ukraine, taking into account foreign experience in this direction.

The current concept of the EU internal market is considered more broadly and holistically. It includes not only economic integration but also consumer safety, labor policy, protection of social rights, and the environment. An important element of the effective functioning of the internal market is also the institution of state aid to economic entities, which provides for the possibility of attracting public investment and control over the efficiency of public resources. The provisions of the Association Agreement between Ukraine and the EU provide for the possibility of implementing, in the national legislation of Ukraine, the institution of state aid to economic entities on the model of the EU and contains specific requirements for Ukraine to transform this institution. The article considers the state of the state aid institute in the context of the implementation of the provisions of the Association Agreement. A general analysis of the concept of "state aid", the problems that most often arise and lead to distortions of competition in the market. The provisions of the legal institute of state aid and the compliance of the provisions of the Law of Ukraine "State Aid to Business Entities" with the provisions of the Association Agreement are determined. The compliance of subsidies with forms of state aid in the context of compatibility of state aid with the requirements of proper functioning of the Association Agreement and the possible impact of this institution on trade between the parties to the Agreement are analyzed. It is concluded that the implementation of EU rules on state aid in domestic legislation will promote competition and create a level playing field for businesses. At the same time, the introduction of a subsidy mechanism as a form of state aid provided to companies may be incompatible with the state aid institution and the requirements for the proper functioning of the Agreement and may adversely affect the development of trade with the EU.

The article presents theoretical provisions and some practical recommendations for the formation of a corps of professional judges in Ukraine. It is noted that today in Ukraine a necessary condition for the effective professional activity of judges in the context of ensuring the right to a fair trial is the proper foundations and mechanisms for the formation of a respectable and highly professional corps of judges. It is also concluded that in the context of reforming the judicial system of Ukraine, it is necessary to focus on improving the special (professional) training of candidates applying for the position of judge (judges), as well as take into account the practical experience of foreign (European) countries in order to determine priority areas for improving the mechanism formation of a corps of professional judges in Ukraine on a democratic basis. Here it is advisable to rely on some basic provisions – Recommendation Rec (2004) 4 of the Committee of Ministers of the Council of Europe to member states on the role of the European Convention on Human Rights in university education and professional training (dated 12.05.2004), as well as significantly improve the quality of the system of special (professional) training of persons (candidates) for the positions of judges at the National School of Judges of Ukraine. It is determined that the prospects for further research in this direction are the study of the features of the legal liability of judges in Ukraine, taking into account foreign experience in this direction.
Molecules in Motion
Authors: Quack Martin
Published: May 2022

The group for molecular kinetics and spectroscopy at ETH Zürich investigates the fundamental physical-chemical primary processes of chemical reactions. We have developed a conceptually new approach to derive these primary processes of intramolecular kinetics on time scales leading
into the femtosecond and subfemtosecond domain on the basis of infrared spectroscopy with high frequency resolution but without short-time resolution. Selected applications include intramolecular wavepacket dynamics of chemical functional groups of isolated, individual molecules and IR-laser
chemistry of molecules under infrared multiphoton excitation, hydrogen bond tunneling dynamics in hydrogen fluoride clusters (HF)2 and the tunneling stereomutation of prototypical chiral molecules. One of the greatest current challenges is the elucidation of the influence of the
parity violating weak interaction mediated by the Z-boson of high energy physics on the dynamics of chiral molecules.

Laser ablation-inductively coupled plasma-mass spectrometry is becoming a powerful analytical technique for in situ trace element determination and isotope ratio determination in solids.A number of fundamental studies using a 193 nm ArF excimer and a 266 nm Nd:YAG laser ablation
system were carried out to study the wavelength-dependent ablation behaviour of different materials. New optical arrangements used for the laser beam delivery onto the sample surface and increased fluency at 266 nm show tremendously improved ablation characteristics of this wavelength, especially
for highly transparent samples. The investigations indicate that sample removal is wavelength- and material-dependent.Fast signal acquisition using a new generation ICP-MS with 'Time-Of-Flight' mass analyser, permits more information to be obtained per sample run in respect to traditional
scanning instrumentation. Especially when dealing with samples of small amount and large isotope menus, the capabilities of an ICP-TOFMS result in greatly improved time resolution.The complex matrix introduction in laser ablation leads to a number of interferences, which were studied using
the recently introduced dynamic reaction cell technology in ICP-MS. Gas reactions using hydrogen allow argides to be removed, while maintaining the multi-element capabilities of ICP-MS. A comparison of standard mode and DRC indicates excellent agreement between both modes of operation and
demonstrates the potential of this technique for trace element analysis.
