Çınar, Recai; Çubukçu, İhsan
Basic aim of this study is to appraise consumption understanding of consumer covered by either organizations or mass media tools by the increasing importance of globalization within the terms of “consumption society” and “consumption culture”. There are two parts in the study. In the fist part, the factors affecting consumer’s purchasing behaviours and factors affecting creation of consumer society and consumer culture are considered. In the application part of the study, consumption understandings of consumers, the level of sensitiveness of consumers to the factors that increase consumption and the factors affecting formation of consumption cultere are examined by comparing two seperate studies carried in 1998 and 2008. At he end of the study, we concluded that, consumers of today make up of consumption soceity that depends on consumption objects.

Taskesenlioglu, M. Yasin
Ottoman Empire officially developed scouting into which it fit a paramilitary structure according to its necessities, it aimed ottoman ( Turkish) youth to be grown up as robust people with healthy bodies. Empire's existence in a state of war during a long time, shrinking of its borders constantly and the army's need of soldiers created the necessity of making the youth to be ready for military service. This need made itself felt thoroughly and was on its peek during the World War I. As a matter of fact, Turkish scouting organization born and as a procedure of pre-draft because of the need for soldiers. This practice stood out first as Ottoman Power Associations and then Ottoman Youth Associations. The associations as mentioned before, were influenced the English scouting experience at first, and then, the German one due to state policies. In particular, Ottoman Youth Associations that were active in most part of the country during the World War I were tried to be reestablished during the Republican Era though they had lost their influence totally in 1920. The paramilitary development of Turkish scouting not only hindered the general and private initiatives but also provided basis for later periods. Scouting in the period starting in 1914 which is the official date of foundation in Turkey, has been revived officially in 1923 after War of Indepedence in spite of the negative effects during the World War I.

Aksarayli, Mehmet; Altuntas, Serkan
Enterprises have to make suitable location planning to decrease their product cost and to increase their productivity in our time. The aim of this study is to compare the basic layout types used in arranging inside facility layout with each other by using simulation. Especially in this study, material handling times between machines and ratio of these times in total times were interested. First of all a new production system is designed to the basic layout types used in arranging inside facility layout. And then in the designed production system, machines are arranged for each machine layout types. Machine layout types are transferred to PROMODEL simulation software. Then with the results of analysis, material handling times of different machine layout types and ratio of material handling times in total production time were compared and the results obtained from this analysis were given after commented on this study.

Tasgin, Esen; Nadaroglu, Hayrunnisa; Demir, Yasar; Demir, Nazan
In this work, the carbonic anhydrase was purified from bovine bone marrow and investigated its kinetic properties. Carbonic anhydrase was purified from bovine bone marrow using affinity chromatography by sepharose 4B-L-tyrosine sulphanilamide. During purification steps, the activity of enzyme was measured using p-nitrophenyl acetate at pH: 7.4. Optimum pH and optimum temperature values for bovine bone marrow carbonic anhydrase were determined and then K m and Vmax values for the same substrate were obtained by means of Linewearver-Burk graphics. The purification degree for bovine bone marrow was calculated. The Vmax, and Km values at optimum pH and at 20 °C for the substrate (p-nitrophenyl acetate) were 120.418 uμmol/L min and 2.409 x 103 mM, respectively. The K1 and I50 values for sulfanilamide, KSCN, NaN3 and acetazolamide were determined in bovine bone marrow carbonic anhydrase.

İncele - MakaleYalnız künye2009Scopus SJRQ2First year Turkish science undergraduates' understandings and misconceptions of light
Yalcin, Mehmet; Altun, Sema; Turgut, Umit; Aggül, Fatma
The present study aims to identify first year Turkish Science undergraduates' understandings and misconceptions of the concept of light and its propagation. For this purpose, an instrument composed of four open-ended questions was developed by the researchers. The diagnostic test was piloted with twenty students and modifications were made prior to the final administration of the test. The content validity of the test questions was assessed by two physics researchers and one lecturer. These questions were administered to a hundred first year undergraduates (aged 16-18) enrolled in the Science Teacher Training Department in Ataturk University in Turkey. In addition, the semi-structured interviews of 30-40 min were conducted with the four students whose responses involved common misunderstanding. All interview records were transcribed and analysed. The findings showed that undergraduates' understanding of light is poor and also they have important and prevalent misconceptions. Identified misconceptions, some of which have been reported in the literature, are discussed qualitatively. The misunderstandings identified were compared with those in the literature. The results have some implications for teaching light, suggesting that a substantial revision of teaching strategies is needed.

Kose, Esra Ozay; Pekel, Osman; Hasenekoglu, Ismet
Textbooks have a specific importance since they are used as the main instruction material. It is important to know that whether commonly used textbooks are adequate in terms of content and presentation. This study was performed to examine whether chapters on "photosynthesis" and "respiration" in the Biology-3 textbooks, that are used in secondary schools in Turkey are sufficient in terms of scientific content or not. We provide examples of the identified misconceptions along with their more acceptable alternatives. As a result, it was determined that biology-3 textbooks are insufficient in respect of scientific content. We recommend that biology-3 textbooks must be improved by correcting the scientific content.

Mollamahmutoglu, M.; Yilmaz, Y.
Nowadays, many soil improvement methods have evolved with different materials used. In this study, a series of laboratory tests are carried out to investigate the effect of a polypropylene fiber material on the shear strength and California Bearing Capacity (CBR) characteristics of high plasticity Ankara clay. First, geotechnical properties of Ankara clay are presented. Then, results of unconfined compressive strength, triaxial strength (CU type) and CBR tests conducted on the various polypropylene fiber/clay mixtures (0.1%, 0.2%, 0.3% and 0.4% by dry weight) are given. Samples were compacted at optimum moisture contents and maximum dry unit weights obtained from the standard Proctor compaction effort. Standard Proctor compaction tests and CBR tests revealed that percentage of 19 mm length F type polypropylene fiber did not influence much the optimum moisture content, maximum dry unit weight and CBR values. Unconfined compression tests showed that inclusion of fiber content increased the axial strain at failure. Moreover, consolidated-undrained (CU) triaxial test results exhibited that due to inclusion of 19 mm length F type polypropylene fiber, the cohesion intercept decreased slightly but the internal angle of friction increased considerably.
