Authors: Agustin Wirta , Muharmi Yulya
Published: October 2019

Homeless and beggars are one of the problems in urban areas because they can interfere public order, security, stability and urban development. The efforts conducted are still focused on how to manage homeless and beggars, but not for the prevention. One method that can be done to solve this problem is by determining the age pattern of homeless and beggars by implementing Algoritma Apriori. Apriori Algorithm is an Association Rule method in data mining to determine frequent item set that serves to help in finding patterns in a data (frequent pattern mining). The manual calculation through Apriori Algorithm obtaines combination pattern of 11 rules with a minimum support value of 25% and the highest confidence value of 100%. The evaluation of the Apriori Algorithm implementation is using the RapidMiner. RapidMiner application is one of the data mining processing software, including text analysis, extracting patterns from data sets and combining them with statistical methods, artificial intelligence, and databases to obtain high quality information from processed data. The test results showed a comparison of the age patterns of homeless and beggars who had the potential to become homeless and beggars from of testing with the RapidMiner application and manual calculations using the Apriori Algorithm.

Authors: Astriningsih Nurhapsari , Mbato Concilianus Laos
Published: October 2019

The importance of having a mastery of the English language has motivated language students to learn, not only in class, but also through other informal extra-curricular activities. One of these activities is gathering together in communities of interest. Motivation has been proven to have an impact on the success of learners in organizing their language-learning activities. Via Likert-scale questionnaires and semi-structured interviews, this study has examined motivation towards the study of English amongst members of a community of interest in Yogyakarta, Indonesia. The participants in this study were 85 English language club members, studying across a number of fields in several Yogyakarta universities. Six participants were then chosen for interview. On the basis of quantitative and qualitative analysis, these learners showed a high level of motivation in all aspects, with slight dominance for intrinsic and instrumental motivation. The research offered implications for further study.

Published: October 2019

Ostracism occurs in the real world but causal investigation of the effect of ostracism on antisocial behavior (i.e., aggression) is typically limited by ethical consideration. This lab-based study (N = 131 Indonesian undergraduates) replicated and extended Chester and DeWall’s (2016) work by: (1) measuring the impact of ostracism on direct physical aggression rather than symbolic form of aggression; (2) investigating the role of trait mindfulness as a potential emotion regulation mechanism to replace the mood-improving qualities in aggression; and (3) employing a non-Western sample. We found that after being involved in the CRTT, ostracized participants mood had recovered at least in terms of negative affect. Aggression might have been seen as justifiable once it was followed by an act of restoring control of to not damage the ostracizer’s reputation afterwards. Moreover, we found that trait mindfulness could buffer negative reactions to ostracism by reducing aggressiveness once the negative affect was higher. As a whole, this study may provide a useful framework on whether and when the mechanism of mood improvement as well as individual differences in mindfulness could be incorporated into the intervention strategies for preventing ostracism-related aggression before escalating to violence.

Authors: Parviz M. , Aminnejad B. , Fiouz A.R.
Published: October 2019

In this Paper, a parametric study on pipes buried in soil was performed illustrating the results of blast loading. Effects of various parameters such as the physical properties of water, oil, gas, air, soil, pipes, and TNT have been investigated. The arbitrary Lagrangian-Eulerian (ALE) method was employed using LS-DYNA software. The maximum pressure in a buried pipe explosive was observed at an angle of about 0° to 45° and the minimum pressure occurred at an angle of about 45° to 90°. Therefore, all figures in this study illustrate that fluid pressure levels in buried pipes can help in their stabilization. In generally, by increasing the 1.23 times of liquid density under the explosion, the pressure levels in the soil decreased by 1.3 percent. The gas pressure has been increasing more than oil and water pipes 39.73 and 40.52 percent, respectively.
Indirect Tensile Test as a Simple Method for Rut Resistance Evaluation of Asphalt Concrete
Authors: Zieliński P.
Published: October 2019

The paper presents the dependence of ITS results at the elevated temperature (40°C) on rutting parameters, i.e. proportional rut depth (PRDAIR) and wheel tracking speed (WTSAIR), obtained at the temperature of 60°C. The asphalt mixture samples were prepared in the gyratory compactor, but ITS tests were conducted with typical Marshall press, at a loading rate of 50 mm/min. Correlation analyses show a strong relationships between ITS results and rutting parameters, whereby the correlation coefficients obtained are higher for the PRDAIR parameter (r = −0.88) than WTSAIR (r = −0.81). Using the obtained regression functions, the prediction limits as well as confidence limits were calculated, which allowed to develop criteria for assessing resistance to rutting on the basis of ITS test, and taking into account the technical requirements in Poland.
The Method of Planning the Implementation of Railway Investments Including Risk
Authors: Kowalski J. , Poloński M.
Published: October 2019

Almost every construction investment should contain elements of risk forecasting, whose validity depends, among other things, on the correct assessment of potential threats. These risks were defined by the Authors as risk factors that were characterized and then grouped on the basis of performed research in the scope of their identification. Due to lack of method of scheduling railway investments on the construction market, including risk assessment, a research effort was undertaken [14-17], the result of which is the proposed method. The article presents the main assumptions of the original method of rail investment planning, which on the one hand, will take into account the impact of potential threats identified previously by the Authors, and, on the other, will allow project managers to refer to the conditions in which the implementation of a specific facility is planned. The assumption was made that the method, relatively easy to implement, supported by an appropriate computational program, will encourage teams planning the implementation of railway undertakings to its application and will improve the reliability of the schedules they develop.

Published: October 2019

Jalan merupakan infrastruktur penting untuk pergerakan manusia, barang  dan meningkatkan perekonomian nasional, namun sebagian besar jalan berperkerasan lentur mengalami kerusakan akibat kualitas dari materialnya yaitu aspal dan agregat. Aspal adalah bahan yang tidak terbarukan sehingga akan habis akibat dari penggunaan secara terus menerus. Sehingga diperlukan bahan alternatif sebagai pengganti aspal untuk melapisi agregat yang berfungsi untuk mengurangi erosi. Salah satu bahan alternatif yang bisa digunakan untuk menutupi permukaan agregat adalah limbah plastik Low Density Polyethylene (LDPE). Limbah plastik LDPE  yang digunakan sebanyak 1% - 6% dari berat keseluruhan agregat di dalam campuran. Limbah plastik LDPE dibuat dalam bentuk potongan kecil plastik dengan ukuran  benda uji dibuat  berdiameter 4 " dan tinggi 2,7" dalam bentuk silinder. Pengujian Marshall dilakukan pada semua benda uji. Penambahan limbah plastik LDPE dapat meningkatkan stabilitas hingga 66,70% dan menurunkan kadar aspal hingga 2,5% dibandingkan campuran aspal beton tanpa campuran limbah plastik. Roads are important infrastructure for the movement of people, goods and improving the national economy, but most flexible pavement roads suffer damage due to the quality of their material, namely asphalt and aggregate. Asphalt is a non-renewable material that will run out as a result of continuous use. So we need an alternative material as a substitute for asphalt to coat the aggregate which serves to reduce erosion. One alternative material that can be used to cover aggregate surfaces is Low Density Polyethylene (LDPE) plastic waste. The LDPE plastic waste used is 1% - 6% of the total weight of the aggregate in the mixture. LDPE plastic waste is made in the form of small pieces of plastic with the size of the test specimen made in diameter 4 "and height 2.7" in cylindrical form. Marshall testing is carried out on all test specimens. The addition of LDPE plastic waste can increase stability up to 66.70% and reduce asphalt content up to 2.5% compared to concrete asphalt mixture without plastic waste mixture.
Targets in the use of biologics for asthma

Asthma is a heterogeneous illness. Despite a vast array of treatment options, a significant proportion of patients with asthma continues to lack control of their illness. We now have a new class of asthma therapy in our armamentarium: biologic agents. Presently, the current pricing
for all of the biologic agents exceeds measures of cost-effectiveness. Optimal patient selection, through phenotypic indices, is the only likely way to allow these agents to be cost effective. This review examined the literature regarding biologic agents, which stressed attempts at optimizing
choice.

A DIFICULDADE NA PROMOÇÃO DE MEDIDAS PREVENTIVAS CONTRA O ABUSO SEXUAL INFANTIL NAS ESCOLAS.
Authors: Lessa Camila Bahia , Mayor Andréa Soutto
Published: October 2019

No período de 2011 a 2017, foram notificados 141.105 casos de violência sexual contra crianças e adolescentes (BRASIL, 2018). Apesar das estatísticas alarmantes, a oferta de educação sexual efetiva nas instituições de ensino ainda enfrenta diversas resistências, dificultando o acesso de crianças e adolescentes às informações sobre o abuso sexual infantil (ASI). Segundo diversos autores, a escola se configura como um ambiente privilegiado para a detecção precoce do abuso (SPAZIANI E MAIA, 2015), o que demanda que os profissionais que atuam nela estejam capacitados para exercer as medidas protetivas e preventivas necessárias. Em vista disso, o presente artigo objetivou compreender se na perspectiva de alunos de licenciatura e profissionais da área da educação existe capacitação, durante sua formação, para lidar com possíveis casos de ASI defrontados no ambiente escolar. Foram entrevistadas 3 alunas do curso de Licenciatura em Geografia da Universidade Federal Fluminense (UFF) no município de Campos dos Goytacazes. Foi identificada a predominância da concepção de despreparo profissional para lidar com alunos vítimas de abuso sexual. A defasagem no ensino e na formação dos professores foi apontada como uma das principais causas dessa desqualificação. Conclui-se que a formação acadêmica em licenciatura não tem sensibilizado e preparado seus professores para identificar sinais indicativos de ASI e nem mesmo quanto aos procedimentos para denúncias de possíveis casos nos órgãos competentes. Dessa forma, cria-se uma dinâmica de omissão das instituições de ensino frente aos casos de ASI, possibilitando a perpetuação dos abusos e a dificuldade de implementação de medidas preventivas contra estes.

Diyaspora
teorilerine göre, örf, gelenek toplumsal ağ, değer sistemi ve psikolojik
özellik gibi diyaspora topluluklarının asli kültürel unsurları, yerli toplumda
hâkim olandan çok farklı ve egzotik bir kültür oluşturabilir. Diyaspora
kültürlerinin oluşumunun nedenselliği, muhtevası, yerli toplumlarla etkileşimi
ve üzerindeki etkileri vb. diyaspora araştırmalarının odaklandıkları
konulardır. Çinli Müslümanların psikolojik özelliği üzerine yürütülen
araştırmalar bu hususlar arasında yer alabilir. Çinli Müslümanlar Çin tarihinde
dayanışma bilinciyle tanınmıştır. Bu ruhu tasvir eden “Gökyüzü altındaki Huiler
bir ailedir”, Müslümanlar ve gayrimüslimler arasında yaygın olarak kullanılan bir
Çin atasözüdür.Bu
makalede Çin İslamının tarihsel bağlamında Çinli Müslümanların dayanışma
bilicinin ortaya çıkışı ve gelişmeleri, dini inanç ve sosyolojik teoriler
ışığında tartışılacaktır. Dini inanç ve diyaspora ortamının bu bilincin
gelişimine katkıda bulunabileceği ifade edilecektir. Bunun yanısıra makalenin
son kısmında modern Çin’in politikası ve modernleşme sürecinin, bu dayanışma
bilincini zayıflatıp zayıflatmayacağı tartışılacaktır. Sonuç olarak, bu hususu
daha iyi cevaplamak için, Çinli Müslümanların dayanışma bilinci üzerinde
birbirleriyle etkileşimde bulunan çeşitli unsurların aynı zamanda göz önünde
bulundurulması gerektiğine işaret edilecektir.

1901 yılında basılmış olan Kâmûs-ı Türkî yaşayan ve
konuşulan Türkçeyi esas alması açısından o dönemde yazılmış diğer sözlüklerden
ayrılır. Bu çalışmanın amacı basımından 117 yıl sonra Kâmûs-ı Türkî’de yer alan
deyimleri Türkiye Türkçesindeki biçimleriyle karşılaştırmak, meydana gelen
anlam değişimlerinin boyutlarını tespit etmek ve sınıflandırmaktır. Çalışmanın
birinci bölümünde anlam değişmesi kavramı ve dil bilimciler tarafından yapılan
anlam değişmesi sınıflandırılmaları ele alınmıştır. İkinci bölümde Cruse (2006)
tarafından yapılan anlam değişmesi ölçütlerine uygun olarak deyimler
sınıflandırılmıştır. Son bölümde bulgular değerlendirilmiştir. Çalışmada en çok
tespit edilen anlam değişmesinin anlam kayması olurken anlam iyileşmesi ve
anlam kötüleşmesi en az görülen değişmeler olarak ortaya çıkmıştır.
Development of an Albanian Version of the Questionnaire on Teacher-Student Interaction
Authors: Berisha Kida Edona , Karaj Theodhori
Published: October 2019

A questionnaire for studying teacher-student interaction in Albanian contexts was developed with extensive coverage in the field of educational psychology. The purpose was to adapt and develop an Albanian version of the widely used tool, the Questionnaire on Teacher-Student Interaction. The teacher-student relationship has been found to be very significant in many studies. Students’ academic achievements, emotional and social development, classroom group dynamics, and school dropouts are just some of the issues to be influenced by the nature of the established teacher-student relationship. To better measure students’ perceptions of teachers, clinical scientific data on personality interactions have been adapted and transferred to the contexts of education. With a sample of 300 subjects, the Questionnaire on Teacher-Student Interaction underwent necessary procedures and statistical analyses. Consequently, the original American version of 64 items resulted in 54 items in the Albanian version. Results confirm the reliability and validity of the questionnaire in the Albanian language and reconfirm its general usage for diverse cultures and contexts. Finally, through this study, the dimensions of teacher-student interactions were also measured and documented in the Kosovo context.

Significance of Pelleting The Seed with Phosphate and Lime on The Cultivation of Soybean in Acid Soils in Sitiung, West Sumatera
Authors: Waluyo Setiyo Hadi
Published: October 2019

Several experiments containing 2 field, 2 pot and I rhizotron were conducted to develop a low input agricultural practice(pelleting seed) for production of soybean plant (cv. Tidar) on heavily acid soils of Sitiung, West Sumatra. The field and polexperiments were conducted in Sitiung and in the greenhouse at the Agriculture Division, Center for the Application ofIsotopes and Radiation Technology, National Nuclear Energy Agency, Jakarta, respectively, in 1990 - 1992. The rhizotronexperiment was conducted in 1994 at the Laboratory of Microbiology, Department of Agrotechnology and Food Sciences.Wageningen University. Wageningen, The Netherlands. Lime-pel/eting seeds with the equivalent of 50 kg lime ha·1 increased nodulation, growth and yield both in unlimed and limed soils. Considerable increases in nodulatio, growth and yield were obtained when a small amount of P fertiliser (J 0 kg TSP ha·l ) was incorporated in the lime-pellet. The beneficial effects of both lime-pelleting and [lime+TSPj-pelleting were more pronounced on nodulation than on growth and yield. and greater in umimed soils than in limed soils. Large effects were obtained in nodulation, growth and yield of soybean in field experi1ltl!nts by pelleting seeds with lime or with lime + TSP. However, the pel/eted soybean plants grown in unlimed soils remained small and yields were negligible. To sustain growth and production of soybean in these acid soils, adequate quantities of lime and of P fertiliser would be necessary. In the present study, a combination of broadcast lime at 2.0 t ha-I with [lime+TSPj-pelleting of inoculated seeds was found superior to the application of 7.0 t ha-I of lime with inoculated seeds only. A I toxicity and P deficiency were the main problems in these acid soils. For the low-input production of soybeans considerations shOllld be directed to the correction of these factors.
