One of the reasons behind the success in the business world is the optimal pricing for products and parts. As a matter of fact, it is known that the best price has a very strong effect on income, profitability and growth factors of businesses. Businesses aim to define the best price for the products or the parts taking the quality, performance, and cost triangle into consideration. Knowing the supplier’s price and lead time is strategically important for competitive advantage in enterprises due to its cost-reducing effect. Defining a price for the buyers based on the performance of the product can sometimes be a rather complicated and time-consuming process. Procurement cost is a Key Performance Indicator (KPI) that is vital to supply chain management. The purpose of procurement savings is to reduce procurement costs, improve supplier conditions and reduce product prices. This article focuses on material procurement (supply) cost using regression-based linear performance pricing (LPP), a tool developed for pricing processes to reduce the unit cost of parts in a large automotive original equipment manufacturer (OEM). Although the method is widely used in the automotive industry in the US and Europe, there is a gap in the literature due to the lack of discussion about the applicability of the LPP method. In this context, it is aimed to contribute to the literature with a detailed example to popularize and disseminate the use of the LPP technique in purchasing and pricing processes. However, it was also aimed to show that pricing problems can be addressed with intelligent approaches as an alternative to classical mathematical models in these processes. Since the data in the study are suitable for the fuzzy logic method, the accuracy of the savings obtained from LPP, in the problem was checked with Fuzzy Logic.

This study is based on thermal performance analysis and evaluation of the National Observatory guesthouse with the software SUNCODE-PC. The study is unique owing to its high-altitude site ( 2465 m ) in a remote area, harsh climate (with almost no data available), and functional restrictions of astronomical facilities. The design is thermally evaluated through different modes of application of insulation, materials, types of glazing, window/wall ratios, Trombe walls, winter night insulation, summer ventilation and shading.

Turkish Abstract: Calismamizda, makroekonomik degiskenlerin ulkemizdeki konut kredisi hacmi uzerindeki dinamik etkileri (2005:01)-(2011:09) donemi icin analiz edilmektedir. Degiskenler arasindaki uzun/kisa donemli iliskilerin arastirilmasinda, esbutunlesme testi/vektor hata duzeltme modeli kullanilmistir. Ayrica vektor-otoregresyon, Granger nedensellik testleri, varyans ayristirmasi, etki-tepki analizleri uygulanmistir. Inceleme sonucunda, konut kredisi hacminin uzun donem denge denkleminde, konut kredisi reel faiz orani ile ters yonlu, para politikalari (arzi)/finansal servet (M2), yapi kullanma izin belgelerine gore bina yuz olcumu ve kisi basina reel GSYIH ile dogrusal yonlu iliskili oldugu belirlenmistir. Etki-tepki ve varyans ayristirmasi analizlerinde, konut kredisi hacminde ortaya cikan degisimlerin aciklanmasinda, konut kredisi disindaki en etkili degiskenler, sirasiyla yapi kullanma izin belgeleri, konut kredisi reel faiz orani, kisi basina reel GSYIH ve M2 olarak belirlenmistir. Soz konusu bulgular ulkemizdeki ipotekli konut finansmani sisteminin gelisme kosullarinin konut talebi, piyasadaki faaliyet duzeyi, kredi maliyetleri ve finansal istikrar gibi klasik kosullarin yani sira, bolusum sorunlarinin cozulmesi gibi karmasik sosyo-ekonomik/politik sureclerle de iliskili olabilecegini ortaya koymaktadir.English Abstract: This paper aims to define conditions of mortgage market development in Turkey in a period of (2005:01)-(2011:09) by defining dynamic causal relationships between volume of housing credit and macroeconomic indicators. We employ VAR, cointegration analysis, VECM, Granger causality tests, impulse-response functions and variance decomposition models. In the long term equation, real interest rate variable is negatively and residential buildings floor area according to occupancy permits, real GDP per person and monetary aggregate/financial wealth (M2) variables are positively cointegrated with housing credit. According to impulse-response/variance decomposition findings, the most effective variables on housing credit are consecutively defined as occupancy permits, real interest rate, real GDP per person and M2. Outcome of models also implies that development of mortgage market may be also related to complex socio-economic/politic processes such as solving income inequalities besides conventional conditions involving financial stability, mortgage costs, housing demand and housing market activity level.

The study aims to develop energy conscious dwellings in climatic conditions of Ankara. Since the computer program SUNCODE-PC is used for thermal performance analysis, an hourly climatic data set for an average year has been prepared. Two design proposals are developed and compared: one of them is designed with conventional features and the other is designed energy consciously. Improvement studies are conducted on the energy conscious design.

A patient with a pyogenic granuloma which occurred in an unusual location and at an earlier age is presented. Pyogenic granuloma is not an uncommon entity which may occur on oral mucosa, face and fingers. The most frequent location encountered for oral cavity pyogenic granuloma is the gingiva and the tongue is a rare location for its occurrence. These lesions are usually seen between 11 and 40 years age. Surgical excision and removal of etiological factors are needed for treatment.

Nuclear magnetic resonance and dynamic nuclear polarization (DNP) of the Overhauser effect type in weak magnetic fields have been used to study two types of asphalt cements in a few typical solvents. In this technique the nuclei on diffusing solvent molecules and the free electron present on a small portion of the asphaltene fraction interact magnetically. The main DNP parameters are listed and interpreted by a comprehensive theory for DNP in viscous liquids, colloids, and two-phase systems.
