Impact of flexible and non-flexible classroom environments on learning of undergraduate students
The physical factors, which were studied less often than the other factors affecting students' learning, were considered in this study. The present study investigated the effect of the flexibility and non-flexibity of the physical classroom setting on undergraduate students' learning. The study adopted a mixed-method research design. The quantitative phase of the study employed the quasi-experimental method of research utilizing the pretest-posttest non-equivalent groups design. T Test and the Repeated Measures ANOVA test was used to compare the group means. In the qualitative phase of the study, the students received a questionnaire with open-ended questions to gather their opinions, and the data were analysed in NVIVO 11. There was no significant difference between the experimental and control groups in terms of learning; however, the achievement scores of both groups were found to be high. Furthermore, the views received from both groups indicated that the physical environment influenced learning in terms of motivation and enthusiasm. © 2019 The Author(s).* This study has been supported by Mus Alparslan University Scientific Research Coordination Unit.

Hand-held spectrophotometer design for textile fabrics
In this study, a hand-held spectrophotometer was designed by taking advantage of the developments in modern optoelectronic technology. Spectrophotometer devices are used to determine the color information from the optic properties of the materials. As an alternative to a desktop spectrophotometer device we have implemented, it is the first prototype, low cost and portable. The prototype model designed for the textile industry can detect the color tone of any fabric. The prototype model consists of optic sensor, processor, display floors. According to the color applied on the optic sensor, it produces special frequency information on its output at that color value. In Arduino type processor, the frequency information is evaluated by the program we have written and the color tone information between 0-255 ton is decided and displayed on the screen

The Contradictions of Free Market System and The Impacts of FDI and Foreign Trade on Economy
This paper examines the effects of the FDI and foreign trade (Exports and Imports) as well as their importance in international economic activities. A central subject the study is to examine the impact of FDI and foreign trade on the growth and prosperity status of countries. Whereby the paper examines the role of international business on the developing progress of countries. The economic growth of a country depends on the quantity and productivity of the economic factors. For that reason FDI and Import-Export are most significant economic activities, which have substantial effects on the quantity as well as quality of economic factors in any country. On the other side, customs union, quotas and regional trade pacts deactivate partly or in some cases even completely the projected effects of Smith’s absolute and Ricardo’s comparative advantages theories in the international production cooperation. The study examines this situation from a modern economic point of view

2) While there isn't a significant difference between the pre-test points of the groups, a significant difference has been seen between their final test points in favour of experiment group. It has been seen that the activities that has been prepared according to the Multiple Intelligences Theory has effected the students' success positively.
3) It the has been determined that there is a significant difference between the final test and the permanence test points of the control group but there isn't a significant difference between the final test and permanence test points of the experiment group. It has been seen that the knowledge that have been learned by the activities according to the Multiple Intelligences Theory are more permanant than the ones that have been learned according to the traditional methods.
At the end of the research, there are some suggestions that are made by researcher according to the data
Effect of parathyroidectomy timing in kidney transplant recipients on graft function
Objectives: Persistent hyperparathyroidism can have a deleterious effect on graft function in kidney transplant recipients, although serum calcium, phosphorus, and parathyroid hormone levels tend to normalize after successful transplant. Parathyroidectomy can result in sustained amelioration of persistent hyperparathyroidism despite graft failure risk and unfavorable graft outcomes. Data on this issue are limited and conflicting. Here, we evaluated the effects of parathyroidectomy on graft function in kidney transplant recipients.Materials and Methods: This retrospective study included 249 adult kidney transplant recipients (121 deceased-donor/128 living-donor; 142 males/107 females; mean age of 39.3 +/- 11.6 y; mean follow-up of 46.5 +/- 23.5 mo). Participants were grouped as those without (n = 222), those with pretransplant (n = 12), and those with posttransplant (n = 15) parathyroidectomy. Graft outcomes and serum calcium, phosphorus, and parathyroid hormone levels were studied.Results: Serum calcium levels at baseline and at 1, 3, 6, and 12 months and parathyroid hormone levels at baseline and at 6 and 12 months were higher and serum phosphorus levels at 3, 6, and 12 months were lower in the posttransplant parathyroidectomy group versus the other groups (P .05).Conclusions: Parathyroidectomy resulted in sustained decreased levels of serum calcium and parathyroid hormone. We observed no graft failure risk associated with parathyroidectomy in our study. Parathyroidectomy before transplant is advantageous with better graft function
Weight gain in kidney transplant recipients: Risks, cardiovascular outcome and management
Kidney transplantation (KT), which is by far the most frequently carried out transplantation globally, is generally accepted as the best treatment both for quality of life and cost effectiveness in end stage renal disease patients although other renal replacement therapies are present. In spite of considerable progress in immunosuppressive and supportive treatments, a number of factors still interfere with the complete success of KT. Cardiovascular (CV) disease is the leading cause of death in renal transplant recipients (RTR). They are at an increased CV risk because of advanced age and adverse effects such as weight gain, hypertension, glucose intolerance, diabetes and dyslipidemia. The determinants that lead to atherosclerosis in RTRs are similar to those in the general population. Excessive weight gain that leads to obesity is quite common after KT. This is often attributed to corticosteroids and other immunosuppressive drugs. Average weight gain in 1year posttransplant period have been reported to be 8-14 kgs. Risk factors for weight gain are feeling of well-being, unrestricted diet, increased appetite, ethnicity, age at the time of transplant, sex, pre-existing obesity, dialysis modality, socioeconomic status and donor type. Obesity has long been associated with an increased risk for coronary heart disease. The risk is compounded by the common coexistence of other risk factors associated with obesity. It is uncertain how much of the risk is due to obesity alone. Furthermore, the mechanisms by which obesity, particularly abdominal obesity, cause or accelerate coronary atherogenesis are also uncertain. Abdominal fat is a strong predictor of mortality after adjustment for total-body fat, and waist circumference correlates highly with abdominal fat. Body mass index (BMI) apart, anthropometric measures of abdominal obesity and body fat distribution like waist circumference and waist/hip ratio appear directly, rather than inversely, associated with all-cause and CV mortality in the general population. In a recent study of RTRs, waist-to-hip ratio but not BMI correlated with CV risk factors, suggesting that central adiposity has a major role in determining CV risk. This shows the importance of identifying ideal measures of adiposity in the evaluation of RTRs because most centers rely solely on BMI. Using only BMI as a cut off value for transplant might not be ideal. In the general population, obesity is widely recognized as a major risk factor for the development of kidney disease. Glomerular hyperfiltration and hypertrophy have long been proposed as possible pathogenic mechanisms in obesity related kidney disease. Many important risk factors for chronic allograft nephropathy, shortened graft function and lower recipient life expectancy have a higher incidence in obese patients, including hypertension, dyslipidemia and type 2 diabetes, although there are conflicting reports in the literature. In addition, posttransplant complications, especially new-onset transplant diabetes mellitus, wound complications and weight gain, are more common in obese RTRs (BMI ≥35kg/m2) in early period. The management of obesity is an important factor necessary to ensure long-term patient and graft survival. Nutritional counseling and exercise should be available immediately after KT for all RTRs. In this article, we review the impact of increased BMI on patient and graft survival, risk factors for the development of post-transplant obesity and available intervention options. © 2012 by Nova Science Publishers, Inc.

A path analysis of the role of communication in developing trust and its effects on employee involvement
Güven, örgütsel performansı etkileyen önemli bir değişken olarak karşımıza çıkmaktadır. İletişim güven geliştirmede oldukça önemli bir role sahiptir. Örgüt içinde güven ortamının oluşabilmesi de çalışanlar arasındaki iletişimle ilişkilidir. Bu nedenle birçok araştırma güven ile iletişim arasındaki ilişkiyi incelemiştir. Ancak bu çalışma, diğerlerinden daha kapsamlı olarak, bilginin niceliğinin, bilginin niteliğinin ve iletişimde açıklığın, güven ile ilişkisinde çalışkan katılımı çıktısıyla birlikte bütüncül bir ilişkisel modelde incelemeyi amaçlamaktadır. Araştırma modeli 176 hastane çalışanı üzerinde yol analiziyle test edilmiştir. İletişim, güven, iletişimde açıklık ve çalışan katılımı ilişkisini konu alan araştırma modeli doğrulanmıştır. Çarpıcı bir sonuç olarak paylaşılan bilginin niceliğinin güven geliştirmede bilginin niteliğinden daha fazla etkiye sahip olduğu tespit edilmiştir.Trust is an important concept in social science research as a key factor in organizational success Communication plays an important role in the development of trust within an organization. Number of researchers have been studied the relationship between trust and communication. This study tests the specific linkages among quality of information, quantity of information, openness, trust, and outcomes such as employee involvement in 176 employees of a hospital. Using path analysis, the research model about the relationship between trust, openness, communication (sharing information) and employee involvement was confirmed in Turkey. We also found that in developing trust the role of quality of information has more effect than the role of quantity of information
