This study intended to verify the feasibility of laser-arc hybrid welding to dissimilar materials joints between high strength steel (AH32) and stainless steel (STS304L). For this, hybrid welding process for dissimilar materials was optimized by varying four parameters (welding speed, welding current, wire feeding rate, welding voltage) through Grey-based Taguchi analysis. A Grey relational analysis of the ultimate tensile strength (UTS), welding depth to width ratio (D/W) and absorbed energy (AE) attained from the Taguchi method can optimize the multiple-performance characteristics of the Grey relational grade. Moreover, hardness values and fatigue strength of welded joints fabricated under welding condition optimized by Grey-based Taguchi analysis were investigated. From the results, it was found that the initial visual test of the welds could be classified as very stringent (Quality B') in quality levels for weld imperfections based on EN ISO 13919-1. In the tensile test of welded joints, the damaged part was in BM of STS304L side. Tensile strength of welded joints in dissimilar materials was comparable to that of STS304L base material. Hardness values at distances of 3mm and 12mm over the bottom surface of welded joints were in the order of WM > HAZ > BM. The hardness of welded joints exhibits within the acceptable range (the maximum value 340Hv~360Hv). Dissimilar materials hybrid welded joints exhibited almost same fatigue strength for similar material STS304L SAW welded joints and lied well above the design curve(level D) for JSSC.

Poka yoke is a very powerful set of technique that either keeps defects from occurring or indicating immediately when a defect occurs. It relies on creativity and common sense to create low cost, effective inspection devices. Like many quality tools, mistake-proofing is not a solution for every kind of defect or quality problem. The poka yoke aims to reduce the rejection, increase the production and avoid fatigue of worker. The beauty of this lies in that anyone, from manager to line supervisor to line employee can bring this concept into service. These devices are used either to prevent the special causes that result in defects, or to inexpensively inspect each item that is produced to determine whether it is acceptable or defective. The paper contains poka yoke fundamentals to improve the production of lever cam follower and to achieve the target of zero defects over the whole process machining.

A simple and reliable square wave anodic stripping (SWAS) voltammetric method at carbon paste electrode (CPE) of Mebeverin hydrochloride (MEB) in pharmaceutical dosage forms (tablet) and in biological fluids (spiked and real urine samples) has been developed and evaluated. Different parameters such as medium, supporting electrolyte, pH, accumulation potential, scan rate and accumulation time, were tested to optimize the conditions for the determination of MEB. The adsorbed form is oxidized irreversibly under optimal conditions, viz., 0.1 M Phosphate buffer (pH~8), 0.1M KCl, a linear concentration ranges from 0.233 to 42.406 µg/mL of MEB, at accumulation times 60, 150 s, can be determined successfully. The standard addition method was used to determine the MEB in pure solutions, tablets and in biological fluids with satisfactory results. The data obtained are compared with the standard official method.

Problem solving method is a student-centered learning model which develops active learning and creative thinking. Using this method has very importance to the discipline of mathematics and it is the nature of mathematical thinking. The purpose of this research is the study of effectiveness of using problem solving method on improving mathematics achievement and creativity of 5th grade primary school students. The sample of the research was consisted of 60 5th grade female primary school students in shahr-Rey, Iran. These students were selected using simple random assignment. In this study quasi-experimental design was implemented which had pre-test/post-test and control group. Experimental group (30 students) was taught problem solving method but control group (30 students) was instructed same science content as traditional teaching methods for same length of time. The Torrance's test of creative thinking (TTCT) and mathematical achievement test were administered to both groups before and after the instruction as a pre and post test. Results of the study reveal that experimental group students have higher mean scores than control group students in post achievement test and post TTCT test while there is no significant difference between experimental and control groups students’ pre achievement test and pre TTCT test scores.

This study was conducted with the aim of analyzing the effect of teaching problem solving skills and Locus of Control on the academic achievement of mathematics students. The research method was quasi-experimental with a pre-test and post-test control group design. The study’s population comprised of students studying in the third year of Guidance school during the academic year of 89-90 in the town of Lordegan from which 30 students were selected via multi-stage cluster sampling. The subjects were then randomly divided into the experimental group who were taught problem solving skills and locus of control and the control group. To measure the reliabilities of the academic achievement tests and the open- trial test the researchers used Cranach Alpha which showed reliability coefficient .88 and .84, respectively. The data were analyzed through covariance analysis. The results showed that the teaching of problem solving skills and Locus of Control had significantly affected the academic performance of the mathematics students (p<0/001). The results of Turkey's post-hoc test revealed that there was no significant difference between the effects of teaching problem solving skills and the teaching of Locus of Control on the academic performance of the experimental group’s students (p>0/001).

In order to investigate the relationship between job satisfaction and its relation with organizational commitment of the staffs of the youth and sport office in Charmahal & Bakhtiari, 150 staffs in this office were selected as the samples. To collect data, there were used the job satisfaction questionnaires (Brown and Pierson, 1993) and the organizational commitment questionnaires (Allen and Mayer, 1991) by a descriptive- correlation survey. To analyze data, there were used descriptive- deduction statistics of the factor analysis(Pierson correlation coefficient). Due to survey results, all components of the job satisfaction such as supervision 0.774, work 0.896, salary 0.753, upgrades 0.826and general satisfaction 0.848 affect on the organizational commitment. There is some meaningful and direct relation between job satisfaction and its aspects with the organizational commitment. These results of this study, as other surveys, showed thatthe lack of the job satisfaction in every office causes forming non commitment toward the organization. The managers should be ensured about the job satisfaction among staffs in order to prevent some internal problems in the organizations.

The objective of this study was to analyze the country-specific attributes that either motivate or determines foreign direct investment (FDI) in a nation. A review of the literature on foreign direct investment revealed specific location attributes that tend to motivate direct investment in a particular location. In order to measure the impact of each of these attributes on foreign direct investment I created a database including each key attribute as a variable and measuring it across countries over a period of five years (2009-2013). The database contains all countries; the primary regions include USA, INDIA as well as a group of “Other” developed and developing nations. Analysis of the countries and variables and their affect on FDI flows. Unfortunately, I found GDP to be the only significant pull factor for U.S. foreign direct investment which indicates that large market size is a major investment determinant for multinational corporations. Other research on an industry-specific basis is necessary to gain a more in-depth analysis of specific variables. Foreign direct investment (FDI) in all over the world in general and in India in particular after the opening up of our market with the adoption of the policies namely globalization, privatization and liberalization has no doubt emerged as one of the most significant source and contributor of external inflow of resources and is one of the most crucial contributors to the capital formation despite their share in the world arena still catching up. When we talk about the term FDI we are talking about a bundle of resources that usually flow into a country including besides capital, production technology, global managerial skills, innovative marketing strategies and access to new markets. A cumulative and an exhaustive study of the overall scenario of FDI in India, FDI in USA in perspective of India investments of FDI in the country, share of top investing countries, sectors attracting highest FDI flows, sector wise technology transfer and approvals. We will also look at the determinants for attracting FDI in the country and also the causes for low flow of FDI and the mechanisms that can be undertaken to make our country attractive enough for investors and vice versa (for USA). This study entirely relies on secondary data collected after a thorough and exhaustive study of various websites, text books, journals, newspapers, magazines and great inputs form various professors and professionals specializing in this area.
