The effects happiness has in the work environment for increasing the effectiveness and efficiency of the employees necessitate the studying and investigating of the concept of happiness in various organizations. Therefore, the current study tries to propose and explain a happiness model in the organization based on national culture. This study has been carried out using a combinatory method and in two sections; namely, the qualitative and the quantitative parts. In the qualitative section, we interviewed experts and university specialists, selected using targeted sampling method, to carry out the identification and classification. In the quantitative section of the study, we utilized the descriptive-survey method and the data gathering tool made by the researcher to elicit the views and opinions of 383 employees of Tehran Municipality, which had been selected using simple random sampling method. Then, we used Pearson’s correlation coefficient and confirmatory factor analysis to analyze the obtained data. The findings show that physical, psychological, spiritual, and social components are among the personal aspects of happiness based on national culture and components such as coherence and sociability are among the organizational aspects of happiness based on national culture.

Paytoop neighborhood in Bojnurd in among those neighborhoods that are confronted with worn-out area problem, while have a potential capability to attract people. In spite of the implemented renovation plans, and having a long history and great capabilities, this neighborhood couldn&rsquot have any progress in constant spatial development, and we are still witnessing a horizontal expansion in the city. The objective of this paper is to analyze the renovation and rehabilitation plan in Paytoop neighborhood, and to prioritize the worn-out area zones in order to implement the Armaghan plan using AHP method and present some strategies to use these spaces optimally, while preserving their identity. In this research, AHP hierarchical method is used to determine the intervention area in the worn-out area. In order to measure and analyze the information we used interview, observation, questionnaire, and library study.

The electronic industry suffers a rapid changing and highly rival environment. Thus, firms have an essential need to strive for acquiring the competitive advantage. Strategy Organizational Agility (SOA) is a tool which enables to assist firms to attain the competitive advantage. Therefore, this study benchmarks the core competencies from a case study within the supply chain network and establishes a set of attributes for augmenting SOA. A novel multi-criteria decision-making structure is proposed to deal with the complex interrelationships among the aspects and attributes. Radial basis function (RBF) neural network can use linear learning algorithm to complete the work formerly handled by nonlinear learning algorithm, and maintain the high precision of the nonlinear algorithm. However, the results of RBF would be slightly unsatisfactory when dealing with small sample which has higher feature dimension and fewer numbers. Higher feature dimension will influence the design of neural network, and fewer numbers of samples will cause network training incomplete or over-fitted, both of which restrict the recognition precision of the neural network. The competence and accountability indicators can the continuously increasing level of agility to be effective. According to the analysis chart production and product design performance indicators alone cannot level a considerable amount of agility to change. But reducing the level of the index level of agility is reduced. Flexibility indices speed and agility level changes can also affect the organization. But with increased levels of these two indicators increased agility rate change indicators will be more flexibility. The results showed that customer knowledge management impact on organizational agility and organizational effectiveness and customer knowledge management through organizational agility has significant positive impact on organizational effectiveness. Finally, some practical suggestions, future research suggestions and research limitations are presented.
