Authors:   Association for International Tea Culture, Kim In-sook
Published: April 2019

The aim of this study is to develop a program suitable for reducing the stress of juvenile probationers, verify the effectiveness, and seek a measure to operate the effective program continuously. As a result of literature research and desire examination for program development, the need to include their own desires, interests, and fun activities in addition to their parents, friends, and economics is identified. Based on this result, the tea-culture therapy program for juvenile probationers was developed. The program is composed of 8 sessions, and each session is a total of 60 minutes followed by 10 minutes introduction, 40 minutes interventions, and 10 minutes to share thoughts. It was designed for juvenile probationers who were attending P city probation office. The effectiveness was
verified through evaluating the difference of pre and post stress scale score of participants. The result showed that the pre score average was 77.7 (SD3.3), and the post score average was 74.9 (SD3.23). This verifies a significant difference between before and after the program. Namely, the degree of stress of juvenile probationers
participated in the tea-culture therapy program has decreased statistically significantly. Therefore, the tea-culture therapy program has been found to be effective in reducing stress for various difficulties that juvenile probationers have. Accordingly, it is recommended that the program continue for them so as to foster emotional stability and reduce stress and improve communication within the family.
A Study on the Background and Characteristics of British Tea
Authors:   Association for International Tea Culture, Sohn Yeon-sook
Published: April 2019

The colony policy that the Great Britain leaded in the 16th century had
repercussions on the modern history all over the world. The greatest country, which
has been very famous for sea culture, suppressed both the Spain and Netherlands by
holding maritime power, and colonialized many countries throughout the world. As a result of this, the country was called The Empire that the Sun never Sets , and has been affecting many areas such as politics, economy and culture, and then the country which formed the British Commonwealth is still sharing traditional culture.
Historically, the suzerain of tea is China. However, the tea had been distributed to China s adjacent countries through the land route so called Silk Road-two passageways: Steppe and Oasis roads. The land route is the central passageway of Eurasia, which prospered from 8 B.C. to 14 A.C. but the Oasis road was linked to Rome. However, the tea, at that time, was not interchanged among countries such as the Great Britain, France or Germany. Europeans started to use sea for adventure and wealth in the 15th century. The trade was carried out through the Silk Road by using canal, but due to many limits, it can t satisfy Europeans surging needs on tea or other invaluable products. To make matters worse, people had more difficulties using the Silk Road because the Turkish conquered the Constantinople in 1453. Therefore, European countries started to focus on pioneering a seaway. While performing colonialization, the country that tried to change world history by using the tea gave rise to historical events, and one of the most interesting interest is to change their attention to both India and China which are rich in tea and labor force. Therefore, some meaningful events in the world tea culture history caused by the British colony are as follows: Boston Tea Party, The Opium War and Colonializing India. In addition, I also described some historical facts such as the birth of British Black tea culture, the improvement of shipbuilding and transportation and the introduction of fermented tea. I adopted both literate and comparative study as a research methodology. I sincerely hope that through this thesis many people recognize some facts that tea represents spiritual culture of each country and is the best beverage to drive human history.

Authors:   Association for International Tea Culture, Kim Jeong
Published: April 2019

This thesis concerns a study on characteristics of the fermented tea in the Korean cultural genes. THE KOREAN STUDIES INSTITUTE released the Korea s representative cultural gene, Society with a community and a natural and mature relationship is a good representation of the Korean sentiment. Korean tea culture was polite to gods and people in spirit, harmonization in social aspect, affection in emotional aspect, and fermentation in internal aspect, it showed a variety of relationships with cultural genes. In particular, because korean has long been drinking rice cake shaped tea, which is fermented by microorganisms, in the history of tea culture in Korea, this thesis studied the Korean cultural genes through the fermented tea by microorganisms. This fermented tea inhibits the activity of enzymes in tea leaves and actively uses microorganisms such as fungi, yeasts, and germs. Among them, the aerobic fermented tea, which is fermented by mold, is a tea made from the longer storage time of the microorganisms control method, and are Chungtaejeon and dark tea. In response, the researcher studied the connection with Korean cultural genes through fermentation of Puer tea and Cheongtaejeon, In particular, rice cake shaped tea had Korean cultural genes such as Etiquette, Society, Fermentation and Affection, which are representative of the cultural genes of Korea, and it was known that it is now being passed down to Korea. In addition, the researcher is preparing an experimental analysis to enhance the utilization value of the Korean fermented tea, which has great cultural value as a mental and cultural product in Korea. It is believed that this will be an important indicator in determining the brand of the fermented tea in Korea in the future.

Authors:   Association for International Tea Culture, Park Hye-ran
Published: April 2019

This study aims at researching the characteristics of practical science thought(Shilhak) and its relationship with tea culture in the latter period of Chosun dynasty. It is said that the thought of Practical Science was helpful in pursuing social and economical and cultural changes in the later period of Chosun Dynasty, and tea culture contributed for the development of Practical Science. Practical Science had removed traditional social inconsistency in Chosun Dynasty, pursued economical development through social changes, developed practical culture through utility and convenience, and expanded tea trade for strengthening national finances and defense ability. Scholars of Practical Science had insisted that the dynasty controlled tea production and trade, and was using tea as an important means to increase national finances. Also the scholars of Practical Science magnified and expanded the superiority of Korean tea culture in the social life through using Chinese tea.
In conclusion, we can say the scholars of Practical Science of the latter period of Chosun Dynasty played an important role to develop tea culture, and tea culture also contributed for the development of Practical Science.

Choroba jako wynik działania czarownicy, bóstwa, demona lub ducha na przykładzie mezopotamskich tekstów magicznych i medycznych
Authors: Nicko-Stępień Paulina
Published: April 2019

The aim of this article is to show the influence of witches, demons, ghosts, and gods on human health in Ancient Mesopotamia. Mesopotamian medicine was based on magic and considered illness to be the work of a supernatural power. Ashu and ashipu – doctors of body and soul – worked together to diagnose and help the patient. Sometimes prayers and magical rituals were necessary for a patient to get well; often, only a herbal mixture was needed. Mesopotamian magical and medical texts describe many kinds of diseases: somatic, mental, and others. Among these are: fever, headaches, leprosy, epilepsy, blindness, impotency, paralysis. This article is an effort to analyse Mesopotamian prescriptions, incantations, and medical interventions and to answer questions about the health of ancient mankind.
Kult świętych a zwycięstwa militarne pierwszych Piastów (od X do początków XIII w.)
Authors: Juzepczuk Monika
Published: April 2019

The aim of this article is to proceed the analysis of the meaning of saints’ and relics’ cult in the military victories of the Piasts, from the 10th to the beginnings of the 13th century. To create a solid political community in Christian Europe it was crucial for a ruler to assure the saints’ protection and convince the subjects about their favorable intercession. The stories about the miracles beneficial for the Piasts shows to themselves and to their subjects that the rulers were chosen by God, who approves their proceedings. The Piasts became beneficiaries of the miracles due to the proper worshipping of the saints and their relics and in response to their Christianization activity. Using the descriptions of the saints’ miraculous support in battles in the texts written for the Piasts as an argument legitimizing and sacralizing their rule is a sign of the early reception and understanding the role of the cult of saints in the ideology of power.
Head-to-Tail Complex of Dishevelled and Axin-DIX Domains: Expression, Purification, Crystallographic Studies and Packing Analysis
Authors: Yamanishi Kumpei , Kumano Wataru , Terawaki Shin-Ichi , Higuchi Yoshiki , Shibata Naoki
Published: April 2019

Background:

Head-to-tail polymerising domains generating heterogeneous aggregates are generally difficult to crystallise. DIX domains, exclusively found in the Wnt signalling pathway, are polymerising factors following this head-to-tail arrangement; moreover, they are considered to play a key role in the heterotypic interaction between Dishevelled (Dvl) and Axin, which are cytoplasmic proteins also positively and negatively regulating the canonical Wnt/β- catenin signalling pathway, but this interaction mechanism is still unknown.

Objective:

This study mainly aimed to clarify whether the Dvl2 and Axin-DIX domains (Dvl2-DIX and Axin-DIX, respectively) form a helical polymer in a head-to-tail way during complexation.

Methods:

Axin-DIX (DAX) and Dvl2-DIX (DIX), carrying polymerisation-blocking mutations, were expressed as a fusion protein by using a flexible peptide linker to fuse the C-terminal of the former to the N-terminal of the latter, enforcing a defined 1:1 stoichiometry between them.

Results:

The crystal of the DAX–DIX fusion protein diffracted to a resolution of about 0.3 nm and a data set was collected at a 0.309 nm resolution. The structure was solved via the molecular replacement method by using the DIX and DAX structures. A packing analysis of the crystal revealed the formation of a tandem heterodimer in a head-to-tail way, as predicted by the Wntsignalosome model.

Conclusion:

The results demonstrated that the combination of polymerisation-blocking mutations and a fusion protein of two head-to-tail polymerising domains is effective especially for crystallising complexes among heterologous polymerising proteins or domains.
Carrageenan: A Wonder Polymer from Marine Algae for Potential Drug Delivery Applications
Authors: Qureshi Dilshad , Nayak Suraj Kumar , Maji Samarendra , Kim Doman , Banerjee Indranil , Pal Kunal
Published: April 2019

Background:

With the advancement in the field of medical science, the idea of sustained release of the
therapeutic agents in the patient’s body has remained a major thrust for developing advanced drug delivery systems
(DDSs). The critical requirement for fabricating these DDSs is to facilitate the delivery of their cargos in a
spatio-temporal and pharmacokinetically-controlled manner. Albeit the synthetic polymer-based DDSs normally
address the above-mentioned conditions, their potential cytotoxicity and high cost have ultimately constrained
their success. Consequently, the utilization of natural polymers for the fabrication of tunable DDSs owing to their
biocompatible, biodegradable, and non-toxic nature can be regarded as a significant stride in the field of drug
delivery. Marine environment serves as an untapped resource of varied range of materials such as polysaccharides,
which can easily be utilized for developing various DDSs.

Methods:

Carrageenans are the sulfated polysaccharides that are extracted from the cell wall of red seaweeds.
They exhibit an assimilation of various biological activities such as anti-thrombotic, anti-viral, anticancer, and
immunomodulatory properties. The main aim of the presented review is threefold. The first one is to describe the
unique physicochemical properties and structural composition of different types of carrageenans. The second is to
illustrate the preparation methods of the different carrageenan-based macro- and micro-dimensional DDSs like
hydrogels, microparticles, and microspheres respectively. Fabrication techniques of some advanced DDSs such as
floating hydrogels, aerogels, and 3-D printed hydrogels have also been discussed in this review. Next, considerable
attention has been paid to list down the recent applications of carrageenan-based polymeric architectures in
the field of drug delivery.

Results:

Presence of structural variations among the different carrageenan types helps in regulating their temperature
and ion-dependent sol-to-gel transition behavior. The constraint of low mechanical strength of reversible gels
can be easily eradicated using chemical crosslinking techniques. Carrageenan based-microdimesional DDSs (e.g.
microspheres, microparticles) can be utilized for easy and controlled drug administration. Moreover, carrageenans
can be fabricated as 3-D printed hydrogels, floating hydrogels, and aerogels for controlled drug delivery applications.

Conclusion:

In order to address the problems associated with many of the available DDSs, carrageenans are
establishing their worth recently as potential drug carriers owing to their varied range of properties. Different
architectures of carrageenans are currently being explored as advanced DDSs. In the near future, translation of
carrageenan-based advanced DDSs in the clinical applications seems inevitable.
Design, Synthesis and In Vitro Anti-Cancer Evaluation of Novel Derivatives of 2-(2-Methyl-1,5-diaryl-1H-pyrrol-3-yl)-2-oxo-N-(pyridin-3- yl)acetamide
Authors: Moghadam Ebrahim S. , Saravani Farhad , Hamel Ernest , Shahsavari Zahra , Alipour Mohsen , Hosseinkhani Saman , Ostad Seyednasser , Amini Mohsen
Published: April 2019

Objective:

Several anti-tubulin agents were introduced for the cancer treatment so far.
Despite successes in the treatment of cancer, these agents cause toxic side effects, including peripheral
neuropathy. Comparing anti-tubulin agents, indibulin seemed to cause minimal peripheral
neuropathy, but its poor aqueous solubility and other potential clinical problems have led to its remaining
in a preclinical stage.

Methods:

Herein, indibulin analogues were synthesized and evaluated for their in vitro anti-cancer
activity using MTT assay (on the MCF-7, T47-D, MDA-MB231 and NIH-3T3 cell lines), annexin
V/PI staining assay, cell cycle analysis, anti-tubulin assay and caspase 3/7 activation assay.

Results:

One of the compounds, 4a, showed good anti-proliferative activity against MCF-7 cells
(IC50: 7.5 μM) and low toxicity on a normal cell line (IC50 > 100 μM). All of the tested compounds
showed lower cytotoxicity on normal cell line in comparison to reference compound, indibulin. In
the annexin V/PI staining assay, induction of apoptosis in the MCF-7 cell line was observed. Cell
cycle analysis illustrated an increasing proportion of cells in the sub-G-1 phase, consistent with an
increasing proportion of apoptotic cells. No increase in G2/M cells was observed, consistent with
the absence of anti-tubulin activity. A caspase 3/7 assay protocol showed that apoptosis induction
by more potent compounds was due to activation of caspase 3.

Conclusion:

Newly synthesized compounds exerted acceptable anticancer activity and further investigation
of current scaffold would be beneficial.
ESDA: An Improved Approach to Accurately Identify Human snoRNAs for Precision Cancer Therapy
Authors: Dong Yan-mei , Bi Jia-hao , He Qi-en , Song Kai
Published: April 2019

Background:

SnoRNAs (Small nucleolar RNAs) are small RNA molecules with approximately
60-300 nucleotides in sequence length. They have been proved to play important roles
in cancer occurrence and progression. It is of great clinical importance to identify new snoRNAs as
fast and accurately as possible.

Objective:

A novel algorithm, ESDA (Elastically Sparse Partial Least Squares Discriminant Analysis),
was proposed to improve the speed and the performance of recognizing snoRNAs from other
RNAs in human genomes.

Methods:

In ESDA algorithm, to optimize the extracted information, kernel features were selected
from the variables extracted from both primary sequences and secondary structures. Then they
were used by SPLSDA (sparse partial least squares discriminant analysis) algorithm as input variables
for the final classification model training to distinguish snoRNA sequences from other Human
RNAs. Due to the fact that no prior biological knowledge is request to optimize the classification
model, ESDA is a very practical method especially for completely new sequences.

Results:

89 H/ACA snoRNAs and 269 C/D snoRNAs of human were used as positive samples and
3403 non-snoRNAs as negative samples to test the identification performance of the proposed
ESDA. For the H/ACA snoRNAs identification, the sensitivity and specificity were respectively as
high as 99.6% and 98.8%. For C/D snoRNAs, they were respectively 96.1% and 98.3%. Furthermore,
we compared ESDA with other widely used algorithms and classifiers: SnoReport, RF
(Random Forest), DWD (Distance Weighted Discrimination) and SVM (Support Vector Machine).
The highest improvement of accuracy obtained by ESDA was 25.1%.

Conclusion:

Strongly proved the superiority performance of ESDA and make it promising for
identifying SnoRNAs for further development of the precision medicine for cancers.

Hablemos de aprendices digitales en la era digital
Authors: Gallardo-Echenique Eliana Esther , Marqués-Molías Luis , Jan-Willem Strijbos Mark Bullen
Published: April 2019

Este artículo se enfoca en una revisión de la literatura del concepto de “nativos digitales” y otros términos relacionados. Más específicamente, versa sobre la idea de una generación homogénea de usuarios prolíficos y hábiles de la tecnología digital nacidos entre 1980 y 1994. En total se revisaron 127 artículos publicados entre 1991 y 2014. Según los hallazgos, no parece existir ninguna definición comúnmente aceptada de un “nativo digital”. El concepto varía entre individuos, sociedades, regiones y naciones, y también con el paso del tiempo. Además, hay una serie de variables además de la edad que pueden ayudarnos a comprender la naturaleza del uso de las tecnologías digitales de los estudiantes. La llamada literatura “digital nativa” demuestra que a pesar de la elevada confianza digital y las habilidades digitales de los estudiantes, su competencia digital puede ser mucho más baja que la de sus “maestros digitales”. Dada la confusión alrededor del “nativo digital” y términos similares, proponemos unificarlos bajo el concepto “aprendices digitales”.

The aim of this study was to determine the traits in peculiar species which most influence their survivability during early growth and development. Eight representative plant species typical for four non-afforested habitats of river valleys were tested. The results showed that for the restoration of natural habitats, the following species are best suited: Allium angulosum (Cnidion dubii, 6440) due to its good seed germination capacity and fast growth rate of its seedlings; Galium boreale (Molinion, 6410) due to the fast growth rate of its seedlings; Tragopogon pratensis (Arrhenatherion elatioris, 6510) due to its large seeds, good seed germination capacity and fast growth rate of its seedlings; regarding to tested species of Festuco-Brometea (6210), the obtained results do not give a definite answer.
Dynamics of a stochastic SIQR epidemic model with saturated incidence rate
Authors: Wang Li-Li , Huang Nan-Jing , O’Regan Donal
Published: April 2019

The purpose of this paper is to propose and investigate a stochastic SIQR
epidemic model with saturated incidence rate. Firstly, we give some
conditions to guarantee the stochastic SIQR epidemic model has a unique
global positive solution. Then we verify that the disease in this model will
die out exponentially if Rs 0 < 1, while the disease will be persistent in
the mean if Rs 0 > 1. Moreover, by constructing suitable Lyapunov functions,
we establish some sufficient conditions for the existence of an ergodic
stationary distribution for the model. Finally, we provide some numerical
simulations to illustrate the analytical results.

We determine the representation theorem, distortion theorem, coefficients
estimate and Bohr?s radius for log-harmonic starlike mappings of order ?,
which are generalization of some earlier results. In addition, the inner
mapping radius of log-harmonic mappings is also established by constructing

pre-Schwarzian, Schwarzian derivatives and Bloch?s norm for non-vanishing
log-harmonic mappings, several properties related to these are also
obtained.

Authors: Malik Ishfaq , Jalal Tanweer
Published: April 2019

In this paper we first introduce N?q?summable difference sequence spaces and
prove some properties of these spaces. We then obtain the necessary and
sufficient conditions for infinite matrices A to map these sequence spaces
into the spaces c,c0, and l?. Finally, the Hausdorff measure of
noncompactness is then used to obtain the necessary and sufficient conditions
for the compactness of the linear operators defined on these spaces.

Authors: Zhang Daochang , Mosic Dijana
Published: April 2019

In this paper, we give expressions for the generalized Drazin inverse of a
(2,2,0) block matrix over a Banach algebra under certain circumstances,
utilizing which we derive the generalized Drazin inverse of a 2x2 block
matrix in a Banach algebra under weaker restrictions. Our results generalize
and unify several results in the literature.
Bound estimates for the derivative of driving point impedance functions
Authors: Örnek Bülent , Düzenlı Timur
Published: April 2019

In this paper, a boundary analysis is carried out for the derivative of
driving point impedance functions, which is mainly used for synthesis of
networks containing RL, RC and RLC circuits. It is known that driving point
impedance function, Z(s), is an analytic function defined on the right half
of the s-plane. In this study, we derive inequalities for the modulus of
derivative of driving point impedance function, |Z'(0)|, by assuming the
Z(s) function is also analytic at the boundary point s = 0 on the imaginary
axis and the sharpness of these inequalities is proved. Furthermore, an
equation for the driving point impedance function, Z(s), is obtained as a
natural result of the proved theorem in this study.
A modified S-type eigenvalue localization set of tensors applications
Authors: Huang Zhengge , Wang Ligong , Xu Zhong , Cui Jingjing
Published: April 2019

Based on the S-type eigenvalue localization set developed by Li et al.
(Linear Algebra Appl. 493 (2016) 469-483) for tensors, a modified S-type
eigenvalue localization set for tensors is established in this paper by
excluding some sets from the existing S-type eigenvalue localization set
developed by Huang et al. (arXiv: 1602.07568v1, 2016). The proposed set
containing all eigenvalues of tensors is much sharper compared with that
employed by Li et al. and Huang et al. As its applications, a criteria,
which can be utilized for identifying the nonsingularity of tensors, is
developed. In addition, we provide new upper and lower bounds for the
spectral radius of nonnegative tensors and the minimum H-eigenvalue of
weakly irreducible strong M-tensors. These bounds are superior to some
previous results, which is illustrated by some numerical examples.
Hölder’s means and fixed points for multivalued nonexpansive mappings
Authors: Dinarvand Mina
Published: April 2019

In this paper, we show some geometric conditions on Banach spaces by
considering H?lder?s means and many well known parameters namely the James
constant, the von Neumann-Jordan constant, the weakly convergent sequence
coefficient, the normal structure coefficient, the coefficient of weak
orthogonality, which imply the existence of fixed points for multivalued
nonexpansive mappings and normal structure of Banach spaces. Some of our
main results improve and generalize several known results in the recent
literature on this topic. We also show that some of our results are sharp.

Generally, progress, productivity and success of any organization depends on the skills and knowledge of their manpower. Thus, better and more accurate training programs in organizations will lead to their growth and efficiency will be eventually achieved. Due to the many advances in the field of medicine, nurses are the backbone of activities in organizations of medical sciences and patient’s affairs. For this purpose, in-service training courses for employees are the most important courses in nursing. This study was conducted at the University of Medical Sciences (Tabriz-Iran) aiming to determine the preferred learning styles of nurses in in-service training courses. In this cross-sectional study, all nurses working in medical and educational centers in a university in the North West of Iran were randomly selected. To collect data, a two-part questionnaire of Kolb’s demographic and social information was used. Data was analyzed by using descriptive and analytical statistics SPSS version 17 software. A total of 470 nurses with an average age of 36.46 ± 5.77 were studied. There was a significant correlation between preferred learning styles of nurses with nursing position, employment status, and income level. There was no a significant statistical relationship between the preferred learning style of nurses with age, work experience and experience in the center. The present study shows that the highest percentage of Kolb’s learning style is related to the preferential converging learning style (57.8%). This study aimed to determine the preferred learning styles of nurse’s in-service training courses in Tabriz University of Medical Sciences. The results of the study showed that converging and assimilating styles were the preferred learning ones among the majority of nurses; these styles are effective and interpreted according to their profession requiring a lot of information and knowledge. Due to the dominance of converging learning style among nurses, it is recommended to use appropriate teaching methods tailored to the style including the use of diagrams, presentations, lectures and self-learning with enjoyable materials.

The Prion Protein (PrP) is mostly known for its role in prion diseases, where its misfolding and aggregation can cause fatal neurodegenerative conditions such as the bovine spongiform encephalopathy and human Creutzfeldt–Jakob disease. Physiologically, PrP is involved in several processes including adhesion, proliferation, differentiation and angiogenesis, but the molecular mechanisms behind its role remain unclear. PrP, due to its well-described structure, is known to be able to regulate copper homeostasis; however, copper dyshomeostasis can lead to developmental defects. We investigated PrP-dependent regulation of copper homeostasis in human endothelial cells (HUVEC) using an RNA-interference protocol. PrP knockdown did not influence cell viability in silenced HUVEC (PrPKD) compared to control cells, but significantly increased PrPKD HUVEC cells sensitivity to cytotoxic copper concentrations. A reduction of PrPKD cells reductase activity and copper ions transport capacity was observed. Furthermore, PrPKD-derived spheroids exhibited altered morphogenesis and their derived cells showed a decreased vitality 24 and 48 hours after seeding. PrPKD spheroid-derived cells also showed disrupted tubulogenesis in terms of decreased coverage area, tubule length and total nodes number on matrigel, preserving unaltered VEGF receptors expression levels. Our results highlight PrP physiological role in cellular copper homeostasis and in the angiogenesis of endothelial cells.
Application of whey retentate as complex nitrogen source for growth of the polyhydroxyalkanoate producer Hydrogenophaga pseudoflava strain DSM1023
Authors: Koller Martin , Hesse Paula , Braunegg Gerhart
Published: April 2019

Polyhydroxyalkanoates, microbial polyesters produced in vivo starting from renewable resources, are considered the future materials of choice to compete recalcitrant petro-chemical plastic on the polymer market. In order to make polyhydroxyalkanoates market-fit, (techno)economics of their production need to be improved. Among the multifarious factors affecting costs of polyhydroxyalkanoate production, increased volumetric productivity is of utmost importance. Improving microbial growth kinetics and increasing cell density are strategies leading to a high concentration of catalytically active biomass within a short time; after changing cultivation conditions, these cells can accumulate polyhydroxyalkanoates as intracellular products. The resulting increase of volumetric productivity for polyhydroxyalkanoates can be realized by supplying complex nitrogen sources to growing microbial cultures. In the present study, the impact of different expensive and inexpensive complex nitrogen sources, in particular whey retentate, on the growth and specific growth rates of Hydrogenophaga pseudoflava was tested.

Based on a detailed kinetic process analysis, the study demonstrates that especially whole (not hydrolyzed) whey retentate, an amply available surplus material from dairy industry, displays positive effects on cultivations of H. pseudoflava in defined media (increase of concentration of catalytically active biomass after 26.25 h of cultivation by about 50%, increase of specific growth rate μ from 0.28 to 0.41 1/h during exponential growth), while inhibiting effects (inhibition constant K i
= 6.1 g/L) of acidically hydrolyzed whey retentate need to be overcome. Considering the huge amounts of surplus whey accruing especially in Europe, the combined utilization of whey permeate (carbon source) and whey retentate (complex nitrogen source) for biopolyester production can be considered a viable bioeconomic strategy for the next future.
Influence of personal variables on entrepreneurial intention: A comparative study between Poland and Spain
Authors: Martínez González José Alberto , Kobylińska Urszula
Published: April 2019

This article analyses the influence of personal variables on entrepreneurial intentions of students from Poland and Spain. The article presents an integrated structural model that has been developed from a set of student perceptions from both countries. A small number of variables included in the model allows explaining and managing the formation of the intention in the context of higher education. This study provides answers to the following questions: What role do personal variables play as motivation in the formation of entrepreneurship in the case of young people? Is the motivation stronger than self-efficacy? What are the differences in the perceptions and ratings of students in Poland and Spain? How can these variables be enhanced? This work used a causal quantitative methodology based on structural equations (PLS) and the Smart PLS-3.0 program. The PLS model was chosen for its advantages in the study of human behaviour and its optimal predictive potential, and because it allows the use of reflective indicators. In the causal model generated with a sample of 721 respondents from Poland and Spain, it was found that personal values initiated the chain of effects that influenced the attitude and, through it, successively resulted in motivation, self-efficacy and entrepreneurial intentions. Therefore, the subjective variables (values and attitudes) have a positive and significant influence on the action variables (motivation and self-efficacy), and these affect entrepreneurial intentions. The absence of significant regional differences in the responses to the items and the causal relationships of the model suggests the possibility of developing integrated and homogeneous programmes for the entire segment, thereby achieving synergies. The results suppose a theoretical and practical contribution to the promotion of entrepreneur intentions of university students inside and outside the educational context, suggesting a possible effect of personal variables on entrepreneurial intentions.
