The most commonly used phytohormone to reduce the impact of drought is 24‑epibrassinolide (EBR). In this study, EBR was applied over two years on young rootstocks of peach (B‑VA‑1) and myrobalan (Vanovice myrobalan) seedlings. Young rootstocks were treated by EBR at different concentrations, IAA and a mixture of EBR with IAA. The best results in seedling height of Vanovice myrobalan in both years had the treatment of 0.05% IAA, 549.69 mm (2016) and 553.77 mm (2017). On the other hand, on the crown root thickness was affected the most in 2016 by treatment of EBR 0.06 ppm (5.5 mm) and in 2017 by EBR 0.01 ppm (7.5mm). At B‑VA‑1 rootstock, the highest seedlings in 2016 were measured after EBR + IAA treatment (1573.18 mm) and in 2017 after IAA treatment (682.75 mm). The highest thickness of the crown root was recorded in 2016 after EBR and IAA (17.76 mm) and in 2017 after EBR 0.1 ppm (8.08 mm) treatments. At more than half of the treatments the control variant was evaluated as a variant with the least satisfying results. According to the results EBR and IAA are possibly increasing the quality of the rootstocks in conditions of a nursery without an irrigation.

Man is made by cells and their life is made by emotions, which in turn determine their health and wealth. Our emotions and feelings direct our physical activities. What we think inside comes outside. What we see outside came from human mind1 . Our thoughts and the emotions are the input and the deeds and the actions are the outcomes. In fact, our emotions and thoughts are our life. As the quality of inputs determine the output. The nature of our emotions and thoughts determine the nature of our life. If the emotions and thoughts are positive then our life will be positive.1 that means we will be happy and healthy. On the other hand, if our thoughts are negative, we will be negative, that is our life will be unhappy and unhealthy. It is believed that, negative emotions such as anger, anxiety, worry, depression and jealous influence our mental and physical health negatively. Therefore the researchers made an attempt in this study to find out the impact of emotions on human health. Thus, the study concludes that the negative emotions such as anger, anxiety, depression, fear and worry and disease are associated. But this may or may not be generalized as it is pertaining to a particular group of people belong to a particular center and a particular area, however it may be a valuable model for a macro study.

We examine the impact of mismatch on entry wages, separations, and wage growth using unique data on worker talents. We show that workers are sorted on comparative advantage across jobs within occupations. The starting wages of inexperienced workers are unrelated to mismatch. For experienced workers, on the other hand, mismatch is negatively priced into their starting wages. Separations and wage growth are more strongly related to mismatch among inexperienced workers than among experienced workers. These findings are consistent with models of information updating, where less information is available about the quality of matches involving inexperienced workers.

Abstract: In recent years many new and modern buildings have emerged in Yogyakarta, on the other hand the existence of kampongs and the natural environment continues to decline, including local wisdom in managing the environment is increasingly abandoned. Kampung Gampingan as a "kampung kota" in the city of Yogyakarta, located on the riverside of the Winongo River. Kampong administrators and it’s citizen Gampingan cooperate to manage and maintain the quality of the kampong environment. For them, the aspect of environmental conservation is very important and considered because it aims to maintain harmonious relationships between humans and the natural environment. The purpose of this paper is to explore information about environmental management in kampong Gampingan, which involves citizens and consider the impact on the natural environment. The results show that community participation, partnerships with various parties (other communities, universities, government and private), and the role of facilitators are very important in the management of kampong based on local wisdom. Community participation is the key to the success or failure of kampong management based on local wisdom.Keywords: kampong management, community participation, local wisdomAbstrak: Dalam beberapa tahun akhir-akhir ini banyak bangunan baru dan modern muncul di Yogyakarta, pada sisi lain keberadaan kampung dan lingkungan alamiah terus berkurang, termasuk kearifan lokal dalam mengelola lingkungan semakin ditinggalkan. Kampung Gampingan termasuk “kampung kota” di kota Yogyakarta, terletak di tepi Sungai Winongo. Pengurus kampung dan warga kampung Gampingan bergotong-royong mengelola dan menjaga kualitas lingkungan kampung. Bagi mereka, aspek pelestarian lingkungan sangat penting dan diperhatikan sebab bertujuan menjaga hubungan harmonis manusia dan lingkungan alam. Tujuan tulisan ini adalah menggali informasi tentang pengelolaan lingkungan di kampung Gampingan, yang melibatkan warga dan mempertimbangkan dampak terhadap lingkungan alam. Hasil penelitian menunjukkan bahwa partisipasi masyarakat, kemitraan dengan berbagai pihak (komunitas lain, perguruan tinggi, pemerintah dan swasta), dan peran fasilitator sangat penting dalam pengelolaan kampung yang berbasis kearifan lokal. Peranserta masyarakat menjadi kunci keberhasilan atau kegagalan pengelolaan kampung berbasis kearifan lokal.Kata kunci: mengelola kampung, partisipasi warga, kearifan lokal

The opening of relationships between United States and Cuba could be a drive for a huge increase in the affluence of tourism to Cuba and especially to the coast areas. Cuba has been for many years an important tourist destination for people from many countries, but almost forbidden for US citizens. The proximity of the USA, its amount of population as well as their great acquisition power will increase in a very substantial way the demand for accommodation and other uses in the proximity of the coasts. There will be a need to implement a package of measures that reduce the impact of such sudden increase in the coastal line. On the other hand that augment in tourism could be an opportunity to improve the standard of life of Cubans. The consideration of different possibilities of such development, the analysis of the damages that each one could cause as well as the measures that could avoid, ameliorate or compensate such effects are the goals that are going to be presented in this paper.

This book examines the impact that Athenian Old Comedy had on Greek writers of the Imperial era. It is generally acknowledged that Imperial-era Greeks responded to Athenian Old Comedy in one of two ways: either as a treasure trove of Atticisms, or as a genre defined by and repudiated for its aggressive humor. Worthy of further consideration, however, is how both approaches, and particularly the latter one that relegated Old Comedy to the fringes of the literary canon, led authors to engage with the ironic and self-reflexive humor of Aristophanes, Eupolis, and Cratinus. Authors ranging from serious moralizers (Plutarch and Aelius Aristides) to comic writers in their own right (Lucian, Alciphron), to other figures not often associated with Old Comedy (Libanius) adopted aspects of the genre to negotiate power struggles, facilitate literary and sophistic rivalries, and provide a model for autobiographical writing. To varying degrees, these writers wove recognizable features of the genre (e.g., the parabasis, its agonistic language, the stage biographies of the individual poets) into their writings. The image of Old Comedy that emerges from this time is that of a genre in transition. It was, on the one hand, with the exception of Aristophanes’s extant plays, on the verge of being almost completely lost; on the other hand, its reputation and several of its most characteristic elements were being renegotiated and reinvented.

Lamprocapnos spectabilis (L.) Fukuhara (bleeding heart) is valued both in the horticultural and pharmaceutical markets. Despite its great popularity, information on the in vitro tissue culture technology in this species is limited. There is also little knowledge on the application of plant extracts in the tissue culture systems of plants other than orchids. The aim of this study is to compare the utility of traditional plant growth regulators (PGRs) and natural extracts—obtained from the coconut shreds, as well as oat, rice, and sesame seeds—in the micropropagation and cryopreservation of L. spectabilis ‘Gold Heart’ and ‘White Gold’. The biochemical analysis of extracts composition is also included. In the first experiment related to micropropagation via axillary buds activation, the single-node explants were cultured for a 10-week-long propagation cycle in the modified Murashige and Skoog medium fortified either with 1.11 µM benzyladenine (BA) and 1.23 µM indole-3-butritic acid (IBA) or with 10% (v/v) plant extracts. A PGRs- and extract-free control was also considered. In the cryopreservation experiment, the same 10% (v/v) extracts were added into the medium during a seven-day preculture in the encapsulation-vitrification cryopreservation protocol. It was found that the impact of natural additives was cultivar- and trait-specific. In the first experiment, the addition of coconut extract favoured the proliferation of shoots and propagation ratio in bleeding heart ‘Gold Heart’. Rice extract, on the other hand, promoted callus formation in ‘White Gold’ cultivar and was more effective in increasing the propagation ratio in this cultivar than the conventional plant growth regulators (4.1 and 2.6, respectively). Sesame extract suppressed the development of the explants in both cultivars analysed, probably due to the high content of polyphenols. As for the second experiment, the addition of plant extracts into the preculture medium did not increase the survival level of the cryopreserved shoot tips (sesame and oat extracts even decreased this parameter). On the other hand, coconut extract, abundant in simple sugars and endogenous cytokinins, stimulated a more intensive proliferation and growth of shoots after rewarming of samples. Analysing the synergistic effect of conventional plant growth regulators and natural extracts should be considered in future studies related to L. spectabilis.

During the last hundred years our knowledge of the educational institutions of medieval England has steadily increased, both of schools and universities. We know a good deal about what they taught, how they were organised and where they were sited. The next stage is to identify their relationship with the society which they existed to serve. Whom did they train, to what standards and for what ends? These questions pose problems. They cannot be answered from the constitutional and curricular records which tell us about the structure of educational institutions. Instead, they require a knowledge of the people—the pupils and scholars—who went to the medieval schools and universities. We need to recover their names, to compile their biographies and thereby to establish their origins, careers and attainments. If this can be done on a large enough scale, the impact of education on society will become clearer. In the case of the universities, the materials for this task are available and well known. Thanks to the late Dr A. B. Emden, most of the surviving names of the alumni of Oxford and Cambridge have been collected and published, together with a great many biographical records about them. For the schools, on the other hand, where most boys had their literary education if they had one at all, such data are not available. Except for Winchester and Eton, we do not possess lists of the pupils of schools until the middle of the sixteenth century, and there is no way to remedy the deficiency.

Content published in social media (SM) can be motivating. It can induce action, stimulate demand, and shape opinions. On the other hand, it can demotivate, cause helplessness, or overwhelm with information. Still, the impact of SM is not always the same. The paper aims to analyse the relations between sex, personality, and the way social media is used and motivation to take specific actions. The conclusions are founded on a survey (n = 462). The data were analysed with statistical methods. The study revealed that the use of SM has a significant impact on the motivation to act. Browsing through descriptions and photographs of various achievements posted by others in SM increased the intrinsic motivation of the respondents. Positive comments and emojis had a similar effect. Moreover, women and extraverts noted a significantly greater impact of SM on their intrinsic motivation concerning health and beauty effort, travel, hobby, and public expression of opinions than men and introverts. The results can be useful to recruiters. Extravert women that are open to cooperation, thorough, and well-organised are more likely to be active in SM.

Covid-19 are one of the viruses that were widely spreaded in 2019 and are still separate until nowadays. Thailand is one of the countries that are highly infected. The majority of people who are infected with this virus tend to have mild to severe respiratory symptoms. Furthermore, anyone can get sick, and it can lead to death. However, the most common symptoms of this virus are fever, cough, tiredness, and loss of taste or smell, on the other hand, characteristics in a minority of people, such as diarrhea and headaches. Due to the impact of the Covid-19 virus, people have to change their lifestyle to the online form. These changes have impacted mostly on economics and education in particular countries, so this problem also affects anxiety among high school students; who must prepare to apply to the university during the COVID-19 outbreak. In addition, we have collected 151 answers from high school students by surveying in order to know the feelings for entrance to the university during the pandemic situation. We found out that 81.3% of the students are highly affected by covid, and only 0.7% of students are slightly affected. We also found out that 55% of the students are worried about university entrance, and only 2.6% of the students were not worried at all. According to the result, most of the students in Thailand are facing the problem about their education and their entrance for the university which are caused by Covid-19. This may lead to illnesses like depression and anxiety. Keywords: Students, Learning, COVID-19, Thailand, University.
