Published: June 2021

Çalışmada, ideolojik bağlam ve konut planlaması ilişkisi 1920'lerde Sovyetler Birliği'ndeki konut mimarisinin ideolojiyi desteklemesi üzerinden ele alınmaktadır. Ekim Devrimi ve I. Dünya Savaşı sonrasında yaşanan ekonomik zorlukların yanı sıra teknolojik eksiklikler, kadınların işgücüne katılımının sağlanması konut mimarisi kapsamında birçok mimarın ele aldığı çözümleri etkilemiştir. Bu sorunlara çözüm önermek için 1926'da mimari tasarım yarışması düzenlenmiştir. Bu tasarımların çoğunda anaokulları, kütüphaneler, ortak mutfaklar, ortak yeme- içme mekânları gibi ortak alanlar vurgulanmıştır. Narkomfin Komünal Konutu, 1928 yılında Moskova'da Finans Bakanlığı bürokratları için tasarlanmıştır. Narkomfin Komünal Konutu kullanıcıları günlük yaşamlarında yemek yemek, kitap okumak, egzersiz yapmak vb. için ortak alanlara yönlendirilmiştir. Narkomfin Komünal Konutu’nda F tipi konut birimleri komünal hayata geçiş birimi olarak düşünülmüştür. Ancak, zaman içinde F tipi konut birimlerine olan talebin artacağı ve K tipi konut birimlerinin azalacağı varsayımı gerçekleşmemiştir. Bu çalışmada, ideolojik bağlamın konut planlamasına getirdiği yeni tanım örnekler üzerinden irdelenmektedir.
Estimation of Large Household Appliances Stock in the Residential Sector and Forecasting of Stock Electricity Consumption: Ex-Post and Ex-Ante Analyses

Published: June 2021

Energy efficiency offers a wide variety of opportunities that will provide efficient resource utilization, alleviate the pressure of energy costs on the economy and reduce foreign energy dependency, and support in combating the harmful effects of climate change. This paper aims to develop necessary data sets to guide policymakers in their decision-making process to identify energy efficiency policy options through an ex-post analysis. One of the targets of this paper is to determine the large household appliances stock and its electricity consumption, which constitutes an important share in residential electricity consumption over the period of 2005-2019. In light of the findings from the ex-post analysis, electricity consumption scenarios for large household appliances were developed from 2020 to 2030. According to the results, the total stock consumption of the refrigerator and washing machine appliances has reached a plateau, leaving behind an increasing trend due to the improvements in efficiency despite the growth in the stock amounts. Besides, the electricity consumption of freezer, tumble dryer, and dishwasher stock has increased significantly due to the increase in the household ownership rates. The analyses also showed that the total electricity consumption of the large household appliances’ stock increased from 17,973 GWh in 2005 to 23,067 GWh in 2019. In addition, the ex-ante analysis revealed that the electricity consumption of refrigerator stock would show most likely a downward trend until 2030, while deep freezers, tumble dryers, dishwashers, and electric ovens stocks would demand more electricity with the increase in ownership rates. However, the analysis showed an uncertain pathway for the electricity consumption of washing machine stock since annual sales during the projection period would show in which direction their consumption would evolve.
Investigation of the Standard Deviation of Ornstein - Uhlenbeck Noise in the DDPG Algorithm
Authors: BİNGOL Mustafa Can
Published: June 2021

Reinforcement learning is a learning method that many creatures often unwittingly use to gain abilities such as eating and walking. Inspired by this learning method, machine learning researchers have reduced this learning method to subheadings as value learning and policy learning. In this study, the noise standard deviation of the deep deterministic policy gradient (DDPG) method, which is one of the policy learning algorithms, was examined to solve inverse kinematics of a 2 degrees-of-freedom planar robot. For this examination, 8 different functions were determined depending on the maximum value of the output of the action artificial neural network. Created artificial neural networks were trained by using these functions in 1000 iterations with 200 steps in each iteration. After the training, the statistical difference between the groups was examined and it was found that there was no statistical difference between the three best groups. For this reason, the best three groups were retrained 2500 iterations and 200 steps and tested for 100 different test scenarios after the training. After testing, the inverse kinematic equation of the 2 degrees-of-freedom planar robot with minimal errors was obtained with the help of artificial neural networks. In the light of the results, the importance of the choice of the standard deviation of noise and the correct range of selection was presented for researchers who will work in this field.

Authors: SEYİTOGLU Sertaç Samed , AVCIOĞLU Emir
Published: June 2021

One of the most important current issues is obtaining and efficiently using energy, a basic necessity of life. With the continuous development of technology and increase in the world population, energy demands keep increasing. In general, the global energy production needs are met with fossil-sourced fuels. However, due to the fact that fossil fuels will be exhausted over time, together with the damage that is inflicted on the environment, people have sought different resources. Biogas energy is a type of renewable energy source that attracts the attention of researchers. In this study, the potential of biogas that can be obtained from animal wastes within the province of Çorum and its surrounding districts was investigated. The amount of biogas that can be produced in the province and per district has been determined. The quantities of biogas that can be generated from the wastes of bovine (cattle, buffalo), ovine (goat, sheep) and poultry (chicken, goose, duck) was calculated. The calorific value of biogas that can be produced and the amount of electricity that can be generated have also been determined. The evaluations in this study have revealed that the total amount of electricity that can be produced from biogas is 80748.8 MWh per year from cattle waste, 3506.7 MWh from ovine animals waste and 16064.4 MWh from poultry waste. In total, the amount of electricity that can be produced for Çorum province has been determined to be 100319.9 MWh per year. It has been found that CO2 emissions from biogas-generated electricity will be 2608.06 tons. When compared to alternatively sourced electricity, it was found that when the same amount of electricity is obtained from natural gas, CO2 emission will be approximately 20 times higher, and when the electricity is obtained from imported coal, the CO2 emission will be 34 times that produced when using biogas.

Published: June 2021

In this study, hard turning tests were carried out under dry cutting conditions on hardened DIN 1.2367 (55 HRC) steel material. The effect of the cutting parameter (three different cutting speeds, three feed rates and three cutting depths) on the power consumption and sound level values was investigated. A mathematical model has been created to estimate the power consumption and sound intensity. In this study, characterization study has also been carried out for DIN 1.2367 steel material and detailed information about the mechanical properties of the material has been obtained. According to the experimental results, as the feed rate, depth of cut and cutting speed increase; sound level and instantaneous current value are increasing. The increase in the cutting parameters increases the instantaneous current value, but the total processing time is reduced, thus reducing the total power consumption.

Published: June 2021

In this study, an analog control circuit design and implementation are performed by using the K-factor design method for a novel isolated Z-source dc-dc converter with high voltage gain. The closed loop system created by the control circuit ensures a constant output voltage at the converter output although there is a step change in input voltage and load within certain limits. The K-factor design method used to design the control circuit allows obtaining the design of the feedback circuit with a certain flow of mathematical equations. The mathematical method used to calculate the control circuit elements increases the reliability of the closed loop system. In this study, firstly, theoretical study of a closed loop control of a novel Z-source dc-dc converter topology is completed with K-factor design method. Secondly, the theoretical study results are analyzed by implementing a simulation study in PLECS. Lastly, by conducting an experimental study, simulation results and experimental results are compared. As a result, the verification of the experimental study that results in 1% error margin of the simulation study has formed the basis of a reliable control method for a new generation dc-dc converter.

Authors: ŞEREMET TUĞALAY Çiğdem , BAYRAKTAR Özer Hakan , GENÇ Nilüfer
Published: June 2021

Objective: In this study, the effects of early (≤21. d) environmental enrichment and acute heat stress on oxidative stress were investigated and the ability of broilers to cope with later heat stress and adrenocorticotropic hormone (ACTH) treatments were determined.
Material and Methods: Six hundred day-old chicks were randomly assigned to 3 experimental groups as a control (C), environmental enrichment (EE) and environmental enrichment plus heat stress (EE+HS). At 21 d of age, broilers in EE+HS group were exposed to acute heat stress at 38±1 ˚C for 3 h. On the day 42nd, C and EE groups were divided into 2 subgroups as well Control, Control+ACTH, EE, EE+ACTH. While 50 IU ACTH/kg body weight was injected to Control+ACTH and EE+ACTH groups intramuscularly, broilers in C, EE and EE+HS groups were exposed to heat stress and oxidative stress responses of birds were evaluated.
Results: Environmental enrichment did not affect blood corticosterone (CORT), malondialdehyde (MDA) and liver superoxide dismutase (SOD) levels of broilers at 21 d of age. ACTH treatment caused a significant decrease in CORT and MDA concentrations in EE broilers compared to the control group. Exposing birds to heat stress (42nd day) significantly increased CORT, MDA and decreased liver SOD levels in control as compared to EE and EE+HS groups. No significant differences were found in the SOD serum levels between groups. ACTH treatment caused more stress reactions than heat stress.
Conclusion: The results obtained from this study show that exposure of broilers to acute heat stress or treatment of experimental adrenocorticotropic hormone causes preferable reactions in oxidative metabolism. It was concluded that rearing in an enrichment environment beginning from early ages can be recommended as a useful method for adaptation to stress.

Metode penelitian yang digunakan adalah metode penelitian kualitatif. Penelitian ini berlokasi di Negeri Lafa Kecamatan Teluti Kabupaten Maluku Tengah.Hasil penelitian menunjukkan bahwa keberadaan lembaga-lembaga adat dalam kehidupan masyarakat adat dapat menjadi sarana untuk mengawasi dan mengatur pola-pola perilaku seluruh anggota masyarakat adat. Namun, realitas yang tampak terjadi saat ini bahwa keberadaan lembaga-lembaga adat dalam kehidupan masyarakat adat belum mampu melaksanakan tugas dan perannya dengan baik sehingga telah menyebabkan munculnya berbagai masalah adat seperti, diantaranya masalah batas-batas tanah petuanan dan masalah pemilihan raja. Guna mengatasi dan meminimalkan berbagai masalah adat yang muncul maka perlu adanya peningkatan peran lembaga-lembaga adat dan kesadaran seluruh anggota masyarakat adat untuk lebih mengenal serta memaknai nilai-nilai yang terkandung dalam adat-istiadat yang dimiliki. Hal ini penting dilakukan supaya pola-pola perilaku seluruh anggota masyarakat adat dapat mencerminkan dan memperkokoh eksistensi masyarakat adat. Masih kurangnya peran lembaga adat dimaksud sebagaimana yang tampak pada Negeri Lafa sebagai salah satu negeri adat yang terdapat di Pulau Seram. Lembaga adat di Negeri Lafa, seperti lembaga saniri hingga saat ini belum mampu melaksanakan perannya dengan baik. Hal ini disebabkan oleh masih kurang terjalin interaksi antara anggota saniri yang terdiri dari para orang tua dan anak muda sehingga menghambat peran lembaga saniri tersebut.

AbstraCtSquatter settlement is increasingly spreading in various urban corners of Indonesia, including in Semarang Metropolitan City. The reality of existing squatter settlements invaded vacant land, unpreserved and lacked (no) supervision from landowners, eventually forming slum enclaves, one of which was on the railway line in Semarang City. Railways should not be allowed to be used as residential areas. The squatter settlement is inhabited by people on low incomes (economically incapable). Research methods are conducted in a qualitative scriptive way, through empirical observation, interactively, with inductive methods. The approach of the room system is carried out to interpret circum citizen activity related to the request or zoning.Meanwhile, theoretical studies were conducted to help identify and analyze in this study. This research illustrates that squatter settlement occurs in addition to the retardation and poverty experienced by citizens, also due to the inability of the government and its apparatus in terms of supervision (Uncontrolled). Therefore, space arrangement is required (including planning, coaching, implementation, supervision and control).Keywords: squatter settlement, railway AbstrakSquatter settlement makin merebak di berbagai sudut perkotaan di Indonesia, termasuk di Kota Semarang Metropolitan.

The increasing movement causes traffic jams. One of the congestion occurred on Jalan Raya Kaligawe, Semarang. Jalan Raya Kaligawe is a road located close to the coast. So that when the sea water experiences high tide, the road will be inundated by tidal floods. This condition results in very high traffic jams every year. To deal with congestion and overcome the problem of sea water flooding, the government plans to build the Semarang - Demak Toll Road. With the existence of this Toll Road, it is hoped that congestion on the Kaligawe Road will be reduced. But the reduction in congestion needs research. So the researchers conducted a study on the effect of the construction of the Semarang - Demak Toll Road on the performance of the Kaligawe Highway. The purpose of this study, among others, is to determine the level of service, prediction of the diversion of traffic loads and predictions of increasing work on Jalan Raya Kaligawe. This study uses three stages in the research method, namely the identification stage, the data collection and processing stage, and the analysis and conclusion stages. The analysis technique used in this research is the formulation of traffic loading around the location due to development, both at the time and post, added with base traffic to get a real loading on the area of influence with the construction of the Semarang - Demak toll road.

n the development of the existing statistical theory of antennas, new analytical relations are obtained for estimating the average radiation pattern of a digital antenna array. These ratios take into account the variance of rounding errors of the weight coefficients, errors in the amplitude and phase calibration of the antenna, jitter noise and rounding errors of the signal at the output of the analog-to-digital converter. It is shown that most of the factors affect the average level of the side lobes, as in analog antenna arrays. However, the variances of the phase calibration errors and the jitter noise determine the contribution of the new term, which has symmetry in the angular coordinate and has an extremums in the direction of the main beam of the antenna array and in the direction that is mirrored relative to the main beam. It is established that the variances of rounding errors depend on the signal-to-noise ratio and, when performing numerical studies, should be estimated based on the results of experimental studies. It is shown that digital processing in a sliding window reduces the average level of the side lobes by separating the spectral components of the signal and noise.

This study is taken to describe the relationship between the levels of debt, dividend policy and the performance of firms listed in Vietnamese stock market. The dividend policy is proxied by the dividend yield while firm’s performance is measured by ROE, ROA, and P/E. The total number of observations is 552, collecting from 92 listed companies on Hochiminh Stock Exchange during 2012 and 2019. The analysis results from generalized least squares (GLS) models report that the choice of firm’s performance proxy affects the relationship between firm’s performance and leverage as well as dividend policy. While leverage has positive impact on ROE and ROA, it has negative impact on P/E. In contrast, dividend yield ratio is negatively correlated with ROA and P/E but positively correlated with ROE. However, the impact of debt levels on firm’s performance is independent with the choice of leverage proxy. The findings of this research are expected to provide better understanding about the connection between debt, dividend and performance of the firm that can support the managers to make relevant decisions.

Published: June 2021

This study estimates the effects of human capital underutilization on economic growth and productivity. This paper investigated the relationship between underutilization of human capital and economic growth using a variety of econometric tests like the Augmented Dickey Fuller test, the Johansen Integration test, and the ARDL model. The results indicate that, there is a negative relationship between human capital underutilization and economic growth. The results indicate that underutilization of human capital has a greater long-term impact on economic growth than it does in the short run. Reforms to education and training systems are required in order to maximise human capital utilisation and thus increase productivity and economic growth.
Overeducation Among Saudi Graduates in the Labour Market: Incidence and Determinants Across Two Self-Assessment Measures
Authors:   King Abdulaziz University, Saudi Arabia, Alzubaidi Mohammed
Published: June 2021

Education expansion has prompted an extensive body of literature on the issue of overeducation, particularly in developed countries. However, as is the case for many developing countries, little, if any, empirical evidence from Saudi Arabia has emerged on this topic. Using cross-sectional survey data, this study examined the prevalence and possible determinants of overeducation among Saudi graduates in the labour market on the basis of two different self-assessment measures. Results indicated that nearly 50% of Saudi graduates in the study were considered overeducated based on each measure, while about 41% were consistently considered overeducated based on both measures. Using logistic regression models, several individual and job characteristics were deemed as major determinants of the probability of being overeducated across both measures. Furthermore, the two measures largely overlapped and yielded somewhat similar conclusions in terms of both the estimates and determinants of overeducation among graduates. The plausible implications of the results for education and labour market policies are discussed.

The interplay between culture and technology is dynamic. Since ancient times, science has had a major impact on people, and people have determined the general direction of science progress. In this way, there is mutual influence between society and science. Socioscientific issues have emerged as a result of the interaction process between science and society. In this context, it was aimed to examine eighth grade students' attitudes towards socioscientific issues. The study was conducted with 136 eighth grade students studying in a city in the Central Anatolia region of Turkey in the 2018-2019 academic year. Quantitative data collection and analysis methods were used in this study, which aimed to examine the secondary school students’ attitudes towards socioscientific issues. “The Attitudes towards Socioscientific Issues Scale (ATSIS) " was used as data collection tool in the study. According to the findings of the factorial ANOVA test; it was determined that eighth grade students' showed positive attitude on socioscientific issues. While students had positive attitudes related to interest and usefulness of SSI, they also had neither positive nor negative attitudes related to interest and usefulness of SSI. In addition, it was observed that the general attitude levels about socioscientific issues and the mean scores of interest and usefulness, liking and anxiety sub-dimensions did not differentiate according to gender. Based on the findings, the importance of socioscientific issues was emphasized and recommendations were made to program makers, researchers and practitioners on teaching.

Published: June 2021

21st century skills emerge is one of the most crucial competencies that need to be considered in teacher education. With this in mind, the fundamental objectives of this study is to analyze the pre-service teachers’ competencies and perceptions of 21st century skills that are effectively present in today’s world. Explanatory mixed method was applied in this study. The aim of the study is to reveal the adequacy of the undergraduate elementary teaching program in the acquisition of 21st century skills from the perspective of pre-service teachers. In the study, quantitative data was collected through descriptive screening method, and qualitative data was collected through phenomenological analysis. 21st century skills scale was utilized to collect quantitative data, and semi-structured interview form was used to collect qualitative data. The sample of the study consists of 411 pre-service elementary teachers studying at a state university. According to the findings obtained, pre-service teachers perceived themselves quite sufficient in terms of “21st century skills”. Given the qualitative findings, pre-service teachers reported that the learning-teaching processes were ineffective in the context of achieving 21st century competencies. As a matter of fact, 21st century skills are defined as skills that should be acquired within the scope of the elementary teaching undergraduate program. Failure to teach these skills emerges as the most significant limitation of the program. In particular, these skills and evaluations should be incorporated into the curricula content of faculties of education.
