Abstract: The research on potential and opportunity for the beef cattle production of the prototype farmers in the livestock model seeks to solve the burning forest problem and agricultural areas which create smog and climate change in Chiang Mai Province. The research objectives aim to study basic information of prototype farmers who raise beef cattle instead of growing maize, to analysis performance efficiency of beef cattle raising, together with the potential and opportunities for beef cattle production. The research area is conducted in Mae Chaem District, Chiang Mai Province, based on a participatory observation with integrated operational synergies. The research has tried to develop the prototype farmers in transforming agricultural waste (corn husk, corncob, etc.) into silage food to increase nutrients. The empirical results show that the highest cost is found in the type of fattening farming, with fixed cost of 924,000 Thai Baht, as well as variable cost of 85,900 Thai Baht. This type also provided the highest income of 1,118,500 Thai Baht. Meanwhile, the highest profit belongs to the type of field release with an amount of 193,250 Thai Baht. Analyzing the performance efficiency, the type of field release shows the highest profit, with an amount of 11,600 Thai Baht. Meanwhile, the enclosure-raised beef cattle have the lowest efficiency because it possesses the lowest profit at 7,756 Thai Baht. Based on the SWOT analysis, the strength shows that Thai farmers have more experiences in cattle farming and breeding cattle. The weaknesses expose that most farmers and beef cattle cooperatives have no long-term planned production, marketing goals, and lacking working capital. The opportunities are the government sector highly supports investment in the beef cattle industry in terms of investment and various resources. Moreover, there are more advantages in logistics and supply chain management for beef cattle exports to neighboring countries because there are a path and linkage of the logistics systems. Finally, the threats indicate the shortages of raw materials and no concentrated food production plants in some areas result in higher food transportation costs.

Abstract: Introduction: In this study, differentiation of individual values and self-efficacy perception of adolescents is analyzed in terms of some variables. In addition, the predictive power of self-efficacy for individual values was analyzed. \r\nMethods: The Individual Values Scale and the Self-Efficacy Scale for Children were applied to 390 adolescents at the high school level. The results showed that self-efficacy and individual values become different in terms of gender, academic success perception, class and parental attitudes. \r\nResults & Conclusions: In this respect, it was determined that students\' self-efficacy differentiation was small according to their gender, class (n2=.022, Cohen\'s f=.15), and family attitudes (n2=.054, Cohen\'s f=.24), and moderate according to their GPA\'s (n2=.068, Cohen\'s f=.27), (p<.001). Also, it was determined that the individual values differed moderately according to family attitude (n2=.080, Cohen\'s f=.29) and GPA (n2=.086, Cohen\'s f=.31), and slightly according to gender (p<.001). On the other hand, significant relationships were found between individual values and self-efficacy, and self-efficacy was found to predict individual values positively (p<.001). The implications for psychological guidance were discussed and the importance of these results to the benefit of society was emphasized. In the 3rd model, self-efficacy (?=-. 386), social self-efficacy (?= .274) and gender (?=-. 064) significantly predicted individual values in high level (R=.53, R2=.28).

Abstract: Abstract. Emotional Intelligence (EQ) has been one of the paradigms influencing the education-training approaches since the beginning of the two thousand. Emotional intelligence can be defined as the ability to use emotions in the right place, at the right time and to use personal and professional aims in a balanced manner. It can be argued that the efficient use of emotional intelligence qualifications is a required process in classroom management and school environment, where teachers achieve their professional aims as a profession in which emotional intensity is experienced. This study aims at determining the emotional intelligence qualifications of teachers who work in secondary schools. In order to attain this aim, an emotional intelligence scale comprising of four subdimensions as sociability, emotionality, self-control, subjective well-being was used. The population of the study comprised of a total of 554 teachers, 472 were from 22 public schools and 82 were from 6 private schools located in Bursa, in the 2017-2018 academic year. According to the statistical analyses of the emotional intelligence scale and its subdimensions the population does not have a normal distribution. The frequency, percentage, arithmetic mean, Mann-Whitney U test, and Kruskal Wallis analyses are conducted. It is found that the emotional intelligence scale, and sociability and subjective-well-being scores are higher in private school teachers compared to public school teachers. A statistically significant difference is found between the groups in the self-control and subjective well-being subdimensions of the emotional intelligence scale with regard to seniority variable. The highest subjective well-being scores are observed in teachers with less seniority. Self-control, on the other hand, is higher in teachers with more seniority.

Abstract: Abstract: Tax burden, i.e. the ratio of the tax revenues and the aggregate taxable income, is an important macroeconomic variable and economic policy instrument which account for the tax burden and the revenue structure in the economy. The macroeconomic regulation function in the context of taxation comes to its own mainly over the value added tax (VAT). The effectiveness fiscal policy in general as well as tax policy in particular depends mainly on the VAT-level in the economy. In the framework of this paper we focus on the performance three post-Soviet Republics, Russian Federation, Azerbaijan and Kazakhstan in terms of the VAT-policy and its efficiency. Due to the completely new emergence of the tax system in all three mentioned states, the paper in hand is a kind of assessment of the different economic policy approaches in these three country cases. From this point of view, a comparative analysis of the present situation of the tax system of these countries is an interesting area. We estimate the optimal levels of the tax burden on VAT on the basis of econometric models and the Laffer points of the types I and II were determined for each case study. It should be noted that the Laffer point of the type I is the level of tax burden at which the volume of total output reaches its maximum, and at the Laffer point of the type II, the amount of tax revenue reaches its maximum.

Hide Abstract | PDF Version

Abstract: Working capital management is an important aspect of financial management. Working capital refers to that part of the firmï¿½s capital which is required for financing short term or current assets such as cash, marketable securities, debtors and inventories. It is also known as revolving or circulating capital. Working capital functions in the business as the heart functions in human body. Just like the heart circulates blood in the body, similarly, in working capital, funds are generated and then circulated in the business. When this circulation does not function, the business will be lifeless. Thus, prudent management of working capital is necessary for the success of a business. The main objective of this study was to examine and evaluate the impact of working capital management on profitability of selected manufacturing firms. The quantitative data from financial statements covering a period of 2012-2017 were collected for ten sole proprietorship manufacturing firms which have been selected by purposive sampling method. The research design was explanatory research and profitability was measured in terms of net operating profit (NOP). The study used descriptive statistics, and balanced fixed effect panel regression to analyze the data. The final findings of the study showed that average payment period has significant positive relationship with profitability while sales growth and size of the firm influence significantly in opposite direction on firms profitability.\r\nKeywords: Manufacturing firm, working capital management, liquidity, profitability.

Hide Abstract | PDF Version

Abstract: Civil drones emerged as a means of entertainment, currently carrying cameras, sensors, microphones and other technologies that allows them collect large amounts of information from the air and in inaccessible places, including the capture of private data that can dismantle and disclose the intimate life of the people. In this paper analyzes 3 aspects behind the use of civilian drones: a) personal privacy risks, b) private data included in the information captured, and c) regulations and methods of privacy protection existing. The results reveal that risks to privacy derive from the violation of privacy principles and occur in all spaces where people perform their professional, recreational, personal, family and intimate activities, the collection of information covers all types of visible personal data and exist deficiencies in the regulations and methods of privacy current. The benefits, growth and potential impact of civil drones on society and the economy, make it essential to develop legal frameworks that integrate and regulate, on the one hand, the incursion of drones into the air space and on the other hand, the collection of information, likewise balance and protect the interests and rights of all involved.

CRYPTOPERIOD COUNTER (CC) AND DERIVED KEY PER ACCESS FOR REAL TIME (DEKART)

Volume 75, May 2019
doi: 10.21506/j.ponte.2019.5.6

Hide Abstract | PDF Version

Abstract: Cryptographic algorithms perform encryption operations using an encryption key to protect information, and process decryption is performed only upon authorization to determine the information. However, when there is vulnerability during the key distribution process, a key life cycle with a certain cryptoperiod can provide a basis for an attack target point. Accordingly, this paper proposes a method to have a different cryptoperiod every time the key is created, making it difficult to determine the key distribution time easily. The cryptoperiod in this study has the nonce property and is defined by the maximum key use count instead of time period, which is generally used. In addition, this study proposes a method that prevents side-channel attack using DErived Key per Access for Real Time (DEKART) derived using a cryptoperiod counter (CC) during communication security that employs a symmetric key. This method, which performs encryption and decryption by generating DEKART whenever it approaches the key, can obtain the same effect of using a new key in every encryption and decryption operation. Thus, it is more secure than the masking technique, which is widely used in side-channel attack prevention in general. In addition, it ensures that the cryptoperiods of the originator and recipient are not different and the DEKART value is not mismatched through the synchronization process of the secured CC value. Furthermore, this study verified that the security performance was improved when DEKART was used compared with the experiment that measured the minimum number of plaintexts required during the chosen-plaintext attack (CPA). Moreover, the comparison results after implementing encryption and decryption operations using a secret key and DEKART showed that if the data size was 10 MB, the operation was slower by 72Î¼s on average in encryption and by 414Î¼s on average in the decryption when using DEKART than when using a secret key, which verified that there was no significant difference in the operation speed between them.
