Authors: Huyen Tran Thi , Quoc Le Pham Tan 
Published: April 2021

Summary

Introduction: Ginger (Zingiber officinale Rosc.) is a common spice and precious herbal plant in Vietnam. It contains many bioactive compounds, especially phenolic compounds useful for human health. Hence, the extraction and application of these compounds in medical technology are necessary.

Objective: The goal of this study is to determine the optimal extraction conditions with the assistance of microwave, for instance solvent/material ratio (ml/g), solvent concentration (%, v/v) and extraction time, on the extraction yield of ginger rhizome, such as total polyphenol content (TPC) and antioxidant capacity (AC).

Methods: The dried sample was extracted by microwave-assisted extraction (MAE). TPC and AC of received extract were measured by the Folin-Ciocalteu method and phenanthroline assay. The optimization process used response surface methodology (RSM) (Central composite face design, CCF) with major influencing factors including solvent concentration, solvent/material ratio and extraction time.

Results: The results showed that the optimal extraction conditions were the ethanol concentration of 60%, ethanol/material ratio of 48.6/1 (ml/g), extraction time of 1 minute.

Conclusion: The maximum TPC and AC peaked at 27.89±1.99 mg GAE/g dry matter and 12.24±0.04 mmol Fe/g dry matter (DM) at optimal extraction conditions. Besides, some factors strongly affected the extraction yield and interacted together.
Global Labor Market Trends and Their Significance for the Future Employees’ Competences
Authors: Przytuła Sylwia 
Published: April 2021

Abstract

Objective: The theoretical purpose of this article is to present social, technological, economic and cultural trends that determine the global labor market, new needs on the labor market and create new competences and professions. The goal of empirical research was to diagnose the most challenging trends for HR specialists and to identify key competencies on the global workforce market.

Methodology: The paper, apart from desk-research and literature review, presents the results of exploratory pilot research. Purposive sampling was applied and the questionnaire was addressed to 44 managers and HR specialists (“key informants”, Myers, 2009) who are participants of postgraduate studies in HR Business Partner, Human Resource Management. The conducted research was idiographic, which means that its conclusions concern only the studied population. But resignation from a broad generalization of results does not necessarily reduce their cognitive value (Chełpa, 2003).

Findings: The biggest challenges for HR were: retention of employees and building their loyalty, shortage of employees on the labor market, management of employees of different generations. It can be said that these challenges are inherent with global trends and problems faced by employers. Respondents pointed to the most desirable competences nowadays and in the near future: IT competencies, intercultural skills, creative and cognitive thinking, ability to work in virtual and multicultural teams. To the key personnel activities which in the next 5 years will gain in importance belonged: mobile working, hiring experts (freelancers), crowd working, portfolio work.

Value Added: This theoretical-empirical study organizes the current results of foresight research on HR trends, in order to develop an aggregated list of the most desirable competencies on the global labor market. Knowledge about the missing, niche competencies of employees pointed out by employers will allow targeting education systems and equipping employees equipped with the most demanded skills and knowledge.

Recommendations: The challenges of the global labor market presented in this article will contribute to disappearance of many previous professions, changes in the nature of work and the emergence of its new forms. In the coming years, many HRM practices will require the revision and implementation of new personnel solutions for recruitment, motivation and career path creation. A flexible career understood as a “portfolio of projects and experiences” of an employee will develop in any direction. Communication model in companies will also be transformed, as mobile devices will become an office, a training room and a personal assistant.

Abstract
In order to understand if differences in light conditions can affect responses of a clonal plant species to increased soil salinity, the long-term effect of two substrate concentrations of NaCl on leaf growth, clonal plasticity and oxidative enzyme (peroxidase and polyphenol oxidase) activity in Hydrocotyle vulgaris L. plants grown at low, moderate and high light conditions was studied. H. vulgaris appeared to be a shade-tolerant species, since both leaf blade and petiole growth was inhibited at low light intensity. At low light intensity, H. vulgaris plants represented characteristics of halophytes with significant stimulation of leaf blade and petiole growth by NaCl, especially at low concentration. Secondary clonal growth was stimulated by increased salinity in low light and, for 25 mM NaCl treatment, even in moderate light. There was more than a five-fold increase of peroxidase activity by 100 mM NaCl treatment in high light conditions, in comparison to two-fold and four-fold increase in low and moderate light, respectively. The existence of different endogenous control mechanisms during H. vulgaris response to light and NaCl at the level of leaf growth, clonal growth and oxidative metabolism could be proposed. The possible ecological meaning of the presented results is discussed in detail.
Psychological Dangers in Participatory Theatre
Authors: Scott Hailey 
Published: April 2021

The emerging popularity of participatory theatre encourages audiences to immerse their senses in the art form. My research aimed to analyze how artists can make their participatory performances psychologically accessible without compromising their creative intentions. The awareness surrounding mental health and psychological safety has grown alongside audiences' and artists' desire to engage with art intimately; thus, artists are encouraged to find a creative way to implement safeguards.
My research began with conducting interviews with mental health professionals and studying texts on psychology. Understanding how emotions are constructed allowed me to explore how an individual's relationship with danger can fluctuate between feelings of exhilaration or the fear of harm. I analyzed Antonin Artaud's Theatre of Cruelty theory and defined the emerging theory of Theatre of Care. I investigated where the danger lies within these theories and how audience emotions can be exploited for the sake of immersion. To provide examples, I conducted case studies of various participatory performances I have attended and researched to illustrate successful applications of audience safety and potential dangers. Finally, I highlighted dramaturgical elements to incorporate psychological safeguards in participatory performance.
My results suggest that individuals construct their emotions from past experiences. Theatre of Cruelty and Theatre of Care theories represent how, although marketed as different audience experiences, they possess many opportunities for triggering psychological harm due to the immersive representation of reality. Consequently, artists must implement psychological safeguards, both dramaturgically integrated into the performance and externally available, to reduce the likelihood of psychological harm and trauma.
Uncal apex movement and positioning in Alzheimer's Disease
Authors: Patel Rahul , Poppenk Jordan 
Published: April 2021

Alzheimer’s Disease (AD) patients have consistently shown declines in declarative memory, consolidation, and in many other cognitive areas. These changes are associated with atrophy and volumetric declines in medial temporal lobe structures, such as the hippocampus. Hippocampal atrophy has been associated with AD. However, the influence of AD atrophy on the position of the uncal apex—an anatomical landmark for the hippocampus—has not been longitudinally examined. The current study’s objective is to investigate changes in the position of the uncal apex of AD patients over the course of two years. The current study draws upon the Alzheimer’s Disease Neuroimaging Initiative (ADNI) data set (adni.loni.usc.edu). For each participant, I obtained demographic data, anatomical MRI images in native space, hippocampal segmentations from the subcortical stream of FreeSurfer (v.5.3.0), and linear transforms to MNI space. Using uncal apex y-positions transformed in MNI space, I found that the uncal apex fell in a more posterior position in AD patients relative to control and that over time, the uncal apex migrates toward a more anterior position in both groups. These results suggest that part of the neuroimaging examinations that are done on AD patients should examine uncal apex positions as a biomarker of early AD progression. Future directions and limitations are discussed

إن الباردابلوماسية مصطلح معاصر تبلور نتيجة التطور السريع والمتلاحق في مجال العلاقات الدولية والدبلوماسية ، يوازي دور الدولة من الموضوعات والجهات والأطراف والنفوذ والتأثير والتأثير المتبادل ، بشكل لم تعد الدولة الطرف الرئيس إن لم نقل الوحيد في رسم وتنفيذ السياسة الخارجية كما كان متعارفاً عليه في السابق ، بل أن إستراتيجية الدولة في كيفية رعاية مصالحها ترسم شكل الدبلوماسية في عالم اليوم المعولم هي التي تحدد الطرف أو الجهة المخططة و المنفذة لها ، لذلك يمكن القول بأن هناك نوع من توزيع الأدوار بين الدولة كطرف رئيسي في العمل الدبلوماسي والجهات الأخرى من الفواعل التي ليس دولاً ، وإنما يمارسون العمل الدبلوماسي بمحاذاة الدول والتي تعرف اليوم بالدبلوماسية الموازية أو البارادبلوماسية .
والباردبلوماسية مجال واسع في ممارسة العمل الدبلوماسي من حيث الأداء والمهام ، وترسم لنفسها خارطة طريق لتحقيق الأهداف المرجوة ، من أجل الوصول إلى أفضل النتائج بأقل الجهود الممكنة والمتاحة وبأسرع وقت ممكن .
وفي ظل متغيرات العصر ومتطلباته إن دور وتأثير الفواعل من غير الدول في مجال البارادبلوماسية يمكن إعتباره بأنه أدوار تكميلية وأدوار ثانوية وأدوار إستباقيىة في بعض الأحيان بموجب الموضوعات التي تمارس فيها تلك الفواعل الدبلوماسية الموازية .

BACKGROUND: Medical device-related pressure ulcers/injuries (MDRPU/Is) are a serious concern in health care. PURPOSE: To develop and assess the psychometric testing of a questionnaire to measure nursing students’ attitudes about the care and prevention of MDRPU/Is. METHODS: Based on a review of the literature, a 26-item questionnaire was developed; face validity was assessed by ten (10) nursing students. The modified Lawshe’s model was used, and both the content validity index (CVI) and content validity ratio were calculated. Items with a CVI more than 0.63 were retained. The minimum optimal CVI for the new instrument was 79%. Qualitative assessments were performed by 10 experienced faculty members. One-hundred-and-eighty seven (187) nursing students participated in the construct validity testing of the 11-item questionnaire. The Kaiser-Meyer-Olkin test of sampling adequacy and Bartlett’s test of sphericity were performed. Following analysis of the main components and the varimax rotation, the factor analysis was determined. Internal consistency (Cronbach’s alpha) and test-retest were determined using Pearson’s correlation and intraclass correlation coefficient to evaluate reliability. RESULTS: During the face validity phase of the initial 26 items, 7 items had impact scores less than 1.5. After calculating the CVI and content validity ratio for all items, 8 items did not achieve the desirable score. After performing exploratory factor analysis on the remaining 11 items, the Kaiser-Meyer-Olkin test value was 0.789, and Bartlett’s test of sphericity was 0.0001, which was statistically significant. Internal consistency of items (Cronbach’s alpha of 0.77) showed that all items had a high correlation. The reliability of test-retest was significant using an intraclass correlation coefficient of 0.75 and Pearson’s correlation coefficient of 0.86 at P < .005. CONCLUSION: In this sample of nursing students, the Attitude Towards Medical-device Related Pressure Ulcers/Injuries Questionnaire was valid and reliable. Studies including licensed clinicians are needed to confirm these results.

Pulai (Alstonia scholaris) is a fast growing local species that can be used rehabilitation activities on peat swamp forest. This study aims to obtain information application the response of growth and quality of pulai seedlings to wood vinegar and shade. The research was carried out at orchid exsitu observation site stock and community service and in the silvicultural laboratory of Faculty of Forestry. This study applied an experimental method with a split plot design with a complete randomized design (CRD). The treatment consisted of two factors,“shading” as the main factor and kind of organic vinegar as sub factor. The results obtained were based on observations 12 weeks after planting, the growth percentage of pulai seedlings for the 100%, while ofthen variables in this study had no effect. The main factor is organic fertilizer with 2 levels: chemical fertilizer and wood vinegar, while the shade factor is a main factor that less interest. Results showed that the response of height growth was significantly higher 13.0% to chemical fertilizer than wood vinegar when planted in a shadeless condition. However, if planted in conditions with a shade of 60%, the response was no different. The response of leaves growth to fertilizer is significant when planted under different shade conditions. In the condition without shade, the response of leaves is 11.8% higher compared to wood vinegar. Conversely, in condition with shading 60%, the response the number of leaves growth on wood vinegar was 13.0% higher than that of chemical fertilizer. In this study, the concentration of wood vinegar as much as 4% was not effective enough to increase the enhance of pulai seedlings.Keywoards: Organic vinegar, pulai seedlings, shade
