Published: December 2018

Kooperatifler ortakları
tarafından yönetilen örgütlerdir. Kooperatif yönetimi, kaynaklarını etkin ve
hakkaniyetli bir şekilde dağıtmaya çalışmaktadır. Kooperatiflerin etkin
yönetimi, ortakların yönetime katılımına bağlıdır. Dolayısıyla başarılı
kooperatif uygulamaları için ortakların yönetime aktif katılımı oldukça
önemlidir. Bu çalışmanın ana amacı ortakların kooperatif yönetimine katılım
düzeylerinin belirlenmesidir. Ayrıca, kooperatif yönetiminde daha önce hiç
görev almamış ortakların, görev alma eğilimleri ve toplantılara katılımı
etkileyen faktörlerin belirlenmesi amaçlanmaktadır. Bu amaçla veriler İzmir
ilinde 142 kooperatif ortağı ile yüz yüze yapılan anketler ile elde edilmiştir.
Buna göre, elde edilen sonuçlar tablo ve grafikler halinde özetlenmiştir.
Ortakların yönetime katılım durumları non-parametrik testlerle ortaya
konulmuştur. Ortakların yönetime katılım durumlarını etkileyen faktörler ise
Lojistik regresyon analizi ile test edilmiştir. Elde edilen sonuçlara göre;
genel olarak ortakların yönetime katılım düzeyleri düşüktür. Fakat, ortaklar
ileride yönetimde görev almada istekli olduklarını belirtmişlerdir. Yönetimde
görev alma istekliliği yaş arttıkça azalmakta, eğitim seviyesi arttıkça ise
artmaktadır.

Authors: KOÇ Gökçe , UZMAY Ayşe
Published: December 2018

Türkiye’de kalkınma ve tarım
politikalarının öncelikli hedeflerinden biri tarımsal üretimde örgütlenmenin
arttırılmasıdır, ancak, kooperatif bilinci, kültürü ve güçlü bir
kooperatifçilik yapılanması henüz oluşturulamamıştır. Tarımın en önemli alt
sektörlerinden biri olan süt ve süt ürünleri sektöründe de kooperatiflerin
payının son derece düşük olduğu dikkati çekmektedir. Kooperatifleşmenin
arttırılması, hayvancılığın ve özellikle süt sığırcılığının karşı karşıya
kaldığı sorunların çözümünde etkili bir yöntem ve önemli bir politika aracıdır.
Bu kapsamda, bu araştırmanın temel amaçları süt üretiminde stratejik öneme
sahip olan Trakya Bölgesi’nde küçük ve orta boy süt sığırcılığı işletmelerinde örgütlenmenin
durumunu ortaya koymak, üreticilerin sütlerini kooperatif aracılığıyla
pazarlama olasılığını etkileyen faktörleri belirlemek ve bölgede örgütlenmenin
geliştirilmesi için politika önerileri sunmaktır. Araştırmanın ana materyalini
bölgenin üç ilinde (Kırklareli, Tekirdağ ve Edirne) 108 üretici ile
gerçekleştirilen yüz yüze görüşmeler oluşturmaktadır. Üreticilerin sütlerini
kooperatif aracılığıyla pazarlama olasılığını etkileyen faktörlerin analizinde
lojistik regresyon modelinden yararlanılmıştır. Görüşülen üreticilerin %60.2’si
sütlerini kooperatif aracılığıyla pazarlamaktadır. Model sonuçlarına göre,
üreticinin eğitim seviyesi, çocukların süt sığırcılığında çalışması, üretimden
vazgeçme isteği ve satış fiyatı sütün kooperatif aracılığıyla pazarlanma
olasılığını etkilemektedir. Araştırma sonucunda, kooperatiflerin rekabet
gücünün arttırılması ve işleme tesislerini kurarak piyasada etkinliğinin sağlanmasının
gerekliliği vurgulanmıştır. Bu destekler, bölge üreticilerinin refahının
artması, katma değer ve istihdam yaratılması, ayrıca bölgede sektörün  ülke 
ekonomisi ve ihracatına katkısının arttırılması açısından önemlidir.

Authors: Irsadanar Rafyoga Jehan Pratama , Warsito Tulus
Published: December 2018

This article analyzes Japanâ€™s interest in revoking its self-imposed military export ban in 2014 despite of its decades-long lucrative pacifism. The pacifism implementations includes partial and total military export ban, consecutively in 1967 and 1976. To puzzle out the question, this journal article utilized â€œBalance of Powerâ€ Concept by Morgenthau. This article found out that Shinzo Abe grand vision to transfer and export weaponries is balancing Peopleâ€™s Republic of China assertiveness in East China Sea by (1) reinforcing military alliances and (2) enhancing internal armaments. The alliances were strengthened by distributing weaponries to states in tension with Peopleâ€™s Republic of China and fortifying military industry cooperation with United States. The domestic military buildup was expected to escalate as arm export stimulated their domestic defense industry development. That includes the economic growth stimulus under Abenomics, in which also aimed to increase the military budget that leads to more robust defense.

Convergence or Divergence in Text and Context? Reflections on Constitutional Preambles in the Constitution-making Exercises of Post-independence Cameroon and Post-apartheid South Africa
Authors: Wanki Justin Ngambu
Published: December 2018

In this article, I attempt to establish the need for the convergence of the spirit of the lawâ€”the Preambleâ€”and the letter of the lawâ€”the provisions of the Constitution of Cameroon contained in its articles. First, I adduce prototypes or archetypes of â€˜Jacobin constitutionalismâ€™ and Anglo-Saxon-style constitutionalism as benchmarks through which I evaluate the extent to which the spirit and letter of the law of the Constitution of Cameroon have been converged. Having established the incongruence of the Preamble with these prototypes, I have referred to the Constitution of post-apartheid South Africa as a fitting paradigm that entrenches modern constitutionalism against which the Preamble to the Cameroon Constitution can be compared, revisited and revised. South Africa has been selected based on the view that, as another African country, it would serve as a more appropriate benchmark for reviewing the Preamble to the Cameroon Constitution than those of the United States, France or other Western nations, which might result instead in a skewed logic. Also, both countries have similar legal systems and historical experiences. A juxtaposition of the two constitutional preambles vividly exposes the lapses in the Cameroon example. As a result, I have suggested that the Cameroon Constitution be amended for the purposes of reviewing its Preamble to bring it into line with the conventional requirements of democratic preambles and to transform the formal demands of the Preamble as tangible demands placed on a government through entrenched provisions. Reasons have been advanced in support of the necessity for including preambulatory clauses in a constitution without which the intent of the constitution per se would be deferred.

Published: December 2018

Selection of personnel in organizations is usually a difficult task. The process gets even more complicated when the selection takes place in complex organizations where different areas can work towards multiple objectives. As many areas might be involved in the selection, the process can become complex and hard to manage. Therefore, it is desirable to use decision-making tools to make the process easier. In this article, we propose new methodology for personnel selection based on Multi-criteria Decision Analysis and the integration of qualitative and quantitative data. We demonstrate the selection process on the case of the Mexican football team selection for the 2018 World Cup in Russia. For the purpose of the article, experts’ opinions are used to evaluate the crucial parameters for the selection.

Published: December 2018

Water supply management effectively becomes challenging due to the human population and their needs have been growing rapidly. The aim of this research is to propose hybrid methods based on Singular Spectrum Analysis (SSA) decomposition, Time Series Regression (TSR), and Automatic Autoregressive Integrated Moving Average (ARIMA), known as hybrid SSA-TSR-ARIMA, for water demand forecasting. Monthly water demand data frequently contain trend and seasonal patterns. In this research, two groups of different hybrid methods were developed and proposed, i.e. hybrid methods for individual SSA components and for aggregate SSA components. TSR was used for modeling aggregate trend component and Automatic ARIMA for modeling aggregate seasonal and noise components separately. Firstly, simulation study was conducted for evaluating the performance of the proposed methods. Then, the best hybrid method was applied to real data sample. The simulation showed that hybrid SSA-TSR-ARIMA for aggregate components yielded more accurate forecast than other hybrid methods. Moreover, the comparison of forecast accuracy in real data also showed that hybrid SSA-TSR-ARIMA for aggregate components could improve the forecast accuracy of ARIMA model and yielded better forecast than other hybrid methods. In general, it could be concluded that the hybrid model tends to give more accurate forecast than the individual methods. Thus, this research in line with the third result of the M3 competition that stated the accuracy of hybrid method outperformed, on average, the individual methods being combined and did very well in comparison to other methods.

Published: December 2018

This paper presents the failure analysis of aircraft antenna which is a sub-assembly of Traffic Collision Avoidance System (TCAS) used with Air Traffic Control (ATC) transponder. The base of the damaged antenna (metallic part) is made from Al-based alloy. The micrographs exhibit the typical solidification microstructure consisting of Al-rich matrix along with Si- and Mg-Si-Fe- rich phases. The antenna is coated with the paint consisting of three layers. First and third layers display the presence of Ti and C while second layer consists of Si, Cr and C elements. The small amount of oxygen is also present in all the three layers. The cracks are appeared in the central region of the fin due to impact of external objects (appears to be blankings and particles). Three types of foreign object damage particles are observed on the damaged / hit area. The antenna appears to be damaged during gale as a result of hitting of the large particles lying in aircraft parking area and aircraft engine blankings.

Authors: Alazemi Saud F. E. M. D. , Hilmy Irfan , Adesta Erry Y. T.
Published: December 2018

Rotary hammer forging process is getting popular since it has many advantages comparing to the conventional forging process. The mechanism of the movement in term of orbital motion of the conical upper die become concern of this research. This article present the three stages of the modelling of the rotary hammer forging. The first stage is the development of the orbital motion of the conical upper die. Three-dimensional CAD model of the conical upper die was developed to determine the orbital motion as a function of the four parameters: Nutation, Precession, Spin and Rocking-Die mechanism. A reasonably accurate design of the conical upper die and the workpiece had been developed based on motion because of interaction of conical upper die and upper part of workpiece geometries. The behaviour of orbital motion with any active combination of those four parameters was observed. The second stage was the development of the conical upper die with the specific feature in order to generate a product with an unsymmetrical shape of upper part of the product. The sequence and mechanism of the formation of the upper part of product were generated. The third stage was the analysis of the stress strain state during the formation of the upper part of the workpiece. An elastic-plastic, dynamic analysis of 3D rotary hammer forging mechanism with the concern at the workpiece and their interaction with a model of dies have been performed. Verification of the indentation mechanism of the rotary hammer forging had been done by validating the result with the existing experimental results.

Published: December 2018

Due to superior mechanical and metallurgical performance, Nickel-base Alloys 617 and 276 have been considered as structural material for used in complex and stochastic applications. Surface irregularities such as cracks in the material may be vulnerable to the structural integrity of an engineering component. Void growth behavior is however analyzed using crystal plasticity theory in nickel-based super alloys. Elastic-plastic fracture mechanics base single compact tension specimen has been used to determine the J1C value as a function of temperature of austenitic Alloy 617 and 276 for ductile crack growth behavior. Crack formation is appropriately explained through crack nucleation based on the microstructural heterogeneity properties of the alloys. Alloy 617 showed a fair increased resistance to fracture as temperature increased from ambient to 5000C for duplicate testing, satisfying the EPFM criteria. Whereas the J1C values of Alloy 276 increased gradually with temperature up to 300° C and due to enhanced plasticity in the vicinity of 4000 C this alloy shows inconsistent value. Two-dimensional simulation of J-integral model of these nickel base super alloys at temperature range 1000C to 5000 C has been proposed. Particular focus is given on the load line displacement where crack propagation occurs during the loading phase only. Path independency of J-integral has been clearly demonstrated for both the alloys up to 3000 C employing finite element analysis meshing with 1922 quadrilateral 2D solid elements in ANSYS. Cracks are typically initiated in relation to the level of strain range. A higher strain range initiates cracks due to precipitate shearing, whereas a low strain range initiates cracks with oxidation reactions and carbide diffusion. The values of K1C and crack tip opening displacement for these alloys have been calculated based on the experimental data. Moreover, fracture morphology in the loading and unloading sequences near the crack tip has been analyzed by SEM.

Authors: Abbas Abdalla Abbas Said , Abou-El-Hossein Khaled
Published: December 2018

Bone drilling operations are carried out in hospitals in different surgical operations worldwide (e.g. orthopedic surgeries and fixing bone breakages). It is considered one of the most sensitive processes in biomedical engineering field. During drilling, the most critical problem is the rise in the temperature of the bone above the allowable limit. A Study showed that the allowable limit that must not be exceeded is 50oC. Moreover, if this limit is exceeded, the bone may sustain serious damage, namely, thermal necrosis (cell death in bone tissue). The research in this paper focuses on reducing the temperature rise during bone drilling. A study was conducted to observe the effect of the drill rotational speed, feed rate and drilling depth on the drill bit temperature during drilling of goat and cow bone. Experimental methods were engaged to optimise the drilling parameters in order to achieve an accepted level of drill bit temperature.

Published: December 2018

Problem related with indoor air quality (IAQ), is rapidly becoming a major health issue as people spend almost 90% of their time indoors. Museums were established in Malaysia more than hundred years ago. Since the year 2005, Malaysia has been moving away from constructing new buildings in favour of refurbishing historic and old ones. A healthy environment at the museum building has been identified as one of the important element that must been considered, but it is not sure either IAQ in the museum building provide a good air quality or not. The purpose of this study is to determine the actual indoor environment of the museum building in Melaka. In this study, the IAQ measurement were conduct for six days at the Melaka Sultanate Palace Museum and at the History and Ethnography Museum. During the measurement, IAQ parameters of gaseous pollutant of nitrogen dioxide, sulfur dioxide and carbon dioxide, and particulate matter of fine particles were recorded by using specific IAQ equipment. The finding of this study indicates that the distance of buildings from roadways appears to have an impact on indoor environmental levels, especially for nitrogen dioxide, sulfur dioxide and particulate matter. Based on the results, only gaseous pollutant of sulfur dioxide had not exceeding the acceptable TLV compared to the other IAQ pollutants.

The type of concrete that adopt is self-compact concrete with high compressive strength. The new and alternative method is were used to strengthen the steel rolled columns at low cost by strengthening the weak axis to preventing or minimize buckling of the columns by using high strength concrete self-compacted without main reinforcements with steel section columns reinforced by lacing as single and double so that it work as full composite structural element and there are connections between concrete block and steel column. There are five specimens with the same height of 1450 mm that was classified as the control specimen and the others with different parameters such as lacing configurations, presence of longitudinal dowels and presence of concrete subject to concentric load. All specimens except the control filled with self-compacted high strength concrete. The result showed that as increase in strength in presence of concrete as compared with the control specimen. Control specimen gave strength capacity compared with the others composite specimens; the increased are 50% composite column, 62.50% composite column with single lacing and 75.00% composite column with double lacing respectively. Specimen (CL1CDL2R) increased in strength capacity as compared with the control specimen 87.50% and 7.14% compared with specimen (CL1CDL) because of presence dowels along the specimen height that increase the stiffness of the composite column. Presence of single and double lacing reduced the buckling value because of reduced the effective columns height. Specimen (CC1L1) gave maximum buckling 32.00 mm compared with the others specimens such as CL1C), (CL1CSL), (CL1CDL) and (CL1CDL2R) respectively, there is significant difference in buckling that reduced by 17.19%, 28.13%, 45.31% and 55.63% respectively.

In this paper, regarding the high availability of rice husk ash (RHA) in Guilan province, also, to decrease the geo-environmental issues caused by dumping RHA in the environment, different clay-sand mixtures are stabilized using the combination of cement and RHA. Polypropylene (PP) fibers are also used to decrease the growth of tensile cracks and increase the overall strength of samples. As the main scope, effect of sand content (in different conditions: with and without presence of RHA) on the compressive strength of stabilized and reinforced samples is investigated. In this regard, 28 day cured clay-sand samples are prepared and unconfined compressive strength (UCS) tests are conducted and the results are compared. It is obtained that with addition of 20% sand to the clay samples, their UCS increases in both cases of non-RHA and RHA-stabilized samples. Moreover, such behavior has been observed with the length of studied PP fibers. As the second scope, based on the conducted UCS tests on the 7-, 28- and 90- day cured clay samples, compressive strength of non-RHA samples are almost completely achieved in a 28-day curing period, while samples containing RHA continue to strengthening after such a period toward a 90-day curing period. Next, a simple relationship for the prediction of UCS of cement-RHA stabilized and PP reinforced clay is presented based on the evolutionary polynomial regression (EPR) technique. This relationship can be efficiently applied by construction engineers to obtain the appropriate mixture design for the stabilization of clay with cement, RHA and PP fibers.

La mayoría de las investigaciones en poscosecha de los frutos de Persea americana Mill. están enfocadas en retardar su maduración. En este trabajo se estudió el efecto de la aplicación de extractos no polares obtenidos de ramas, pedúnculo y hojas de aguacate variedad ‘Hass’ sobre el retraso de la maduración del fruto con y sin pedúnculo.  Además, se evaluó la maduración de frutos de P. americana colectados con sus ramas de tamaño original con hojas (ROH) y sin hojas (ROSH), y ramas a la mitad de su tamaño original con hojas (RMH) y sin hojas (RMSH). Las variables medidas en frutos tratados con extractos no polares fueron firmeza, respiración, diámetro ecuatorial y color. En los frutos con ramas se determinó firmeza, diámetro ecuatorial, longitud y color. La firmeza fue determinada con escala hedónica de 5 a 1, la velocidad de respiración (mL CO2 kg-1h-1) con un medidor de CO2, las variables de color (L,a,b) con la aplicación para android ‘Color Grab’, el diámetro ecuatorial y longitud, se midieron con un vernier digital. De acuerdo con los resultados, la presencia del pedúnculo en frutos tratados con extractos hexánicos atrasó su maduración; con una firmeza promedio de 4.3 y coloración verde a los 10 d poscosecha. Los extractos de pedúnculo a 100 y 200 ppm tuvieron un efecto significativo en mantener la coloración verde de los frutos hasta 10 d después de cosecha. La evaluación de madurez en frutos colectados con ramas, demostró que la presencia de hojas retarda su maduración.

In silico molecular docking studies of some phytochemicals against peroxisome-proliferator activated receptor gamma (PPAR-γ)
Authors: Ahmed H. A. , Alkali I. Y.
Published: December 2018

Peroxisome Proliferator-Activated Receptor-γ (PPAR-γ) is a ligand-activated transcription factor and a member of the nuclear receptor superfamily that regulate the gene expression of proteins involved in glucose, lipid metabolism, adipocyte proliferation and differentiation and insulin sensitivity. Thiazolidinediones (TZDs) are one important class of synthetic agonists of PPAR-γ. TZDs are antidiabetic agents that target adipose tissue and improve insulin sensitivity, and they are currently being used in the treatment of type 2 diabetes. The study was carried out in order to discover new phytochemicals that have the ability to stimulate the PPAR-γ using molecular docking studies. AutoDock vina was used as molecular-docking tool in order to carry out the docking simulations. Nine phytochemicals namely plumbagin, quercetin, isovitexin, mangiferin, syringin, lupe-20-ene-3-one, purine 2, 6-dione, diosmetin and β sitosterol and pioglitazone a standard drug were docked against PPAR-γ using AutoDock vina and the results were analyzed using binding affinity. The results revealed that the compounds have significant binding affinity towards the PPAR-γ comparable to pioglitazone the standard drug. Based on the findings of this study these phytochemicals can serve as source of antidiabetic drugs via the mechanism of inhibition of PPAR-γ.

The aim of this study is to investigate the multiple and rapid production of Pogostemon erectus (Dalzell) Kuntze by tissue culture techniques. The shoot tip and nodal explants of P. erectus were isolated and then cultured in Murashige and Skoog (1962) (MS) nutrient media containing thidiazuron (TDZ) and 2,4-Dichlorophenoxyacetic acid (2,4-D) in different combinations. The first shoot formation on the explants was observed on day 15. The number of shoots per explant ranged from 2.85 to 29.39 in the shoot tip explants and from 2.72 to 32.24 in the nodal explants. The maximum number of shoots per explant was obtained in the MS medium containing 0.20 mg/L TDZ + 0.10 mg/L 2,4-D for shoot tip explant (29.39) and in the MS medium containing 0.10 mg/L TDZ + 0.10 mg/L 2,4-D for nodal explant (32.24). The longest shoots in the shoot tip (1.76 cm) and nodal (1.64 cm) explants were determined in MS medium supplemented with 0.10 mg/L TDZ + 0.10 mg/L 2,4-D. Regenerated shoots were rooted in MS medium supplemented with 0.25 mg/L indol-3yl acetic acid (IAA), and then acclimatized to aquarium conditions.
