The purpose of this paper is to develop a model for selecting the best contractor in the Gaza Strip using the Artificial Neural Network (ANN). The contractor's selection methods and criteria were identified using a field survey. Fifty four engineers were asked to fill a questionnaire that covers factors related to the selection criteria of contractors practiced in Gaza Strip. The results shows that the dominant part of respondents (91%) confirmed that the current awarding method "the lowest bid price" is considered one of the major problems of the construction sector, "award the bid to the highest weight after combination of the technical and financial scores" represented 50% of the respondents. The criteria weights were determined based on Relative Importance Index (RII. Ninety-one tenders(13 projects) were used to train and test the ANN model after re-evaluating the contractors depend on the weights of factors to select the best contractor who achieves the highest score. Neurosolution software was used to train the models. The results of the trained models indicated that neural network reasonably succeeded in selection the best contractor with 95.96% accuracy. The performed sensitivity analysis showed that the profitability and capital of company are the most influential parameters in selection contractors. This model gives chance to the owner to be more accurate in selecting the most appropriate contractor.

Professionalizing the teaching workforce has been recognized as one of the primary factors to reforming public education. In response to this challenge, it has been emphasized that an educational leader's role is to support professional learning communities more effectively. Although the academia of educational administration has increasingly drawn the significance of a teacher's professional development, understanding of an educational leader's role and contribution to this effort is quite limited and unclear. This article examines what factors and barriers affect teachers' participation in professional learning communities from the voices and experiences of teachers. The analysis found 1) identification, 2) autonomous will, 3) practical solution for factors to participation and 1) lack of theoretical foundation, 2) financial burden, 3) insufficient time for barriers to participation. In conclusion, the author suggests the strategies for an educational leader who has an important role in developing a teacher's professionalism: 1) create a strong network of university professors and other experts for career advice, 2) make an institutional effort to stimulate teachers' motivation to learn; 3) decrease the teachers' workload, 4) build a synthesized and consolidated system to establish communities.

The purpose of this study is to develop a farm management diagnostic checklist form, which can be applied to any crops. First, upper indexes and subordinate indexes were identified through survey with expert, and weighted values for each subordinate index were calculated through AHP analysis. Second, as a reuslt of Analytic Hierarchy Process (AHP) analysis, marketing management (0.276) was found to be the most important index of all upper indexes. In the case of subordinate indexes, reflecting management evaluation (0.252) of management consciousness, quality enhancement efforts (0.332) of production management, locating new sales outlets (0.323) of marketing management, agriculture accounting (0.300) of finance management, and adjusting shipping dates (0.274) of risk management were found to be the highest. Third, the interval division using weight of farm receiving prices was higher discrimination in comparison to equal interval division of weighted values for each index. The newly developed farm management diagnostic checklist can be applied to any crops, as it utilizes indexes such as management consciousness, production management, marketing management, financial management, risk management, etc. based on professional opinions. In addition, it allows an objective evaluation of farm management situations by utilizing the weighted value of farm receiving prices.

To establish a new creative economy, the worldwide efforts have been made to wriggle out the old economic paradigm after the financial crisis of 2008. When it comes to the limitation of the viability. the start up companies have a high risk of failure. Therefore business incubator (BI) should carry out the role to improve their viability. As for the maximization of the effect on the business incubating services as move in companies, it is important for BI to increase the level of business incubating services by the systemic and scientific measurement. This study showed that the quality of the BI center services was measured by Kano analysis and the previous research as follows. First, BI quality attribute by Timko's customer satisfaction came out into the attractive qualities on the 14 items that amount to the 70% of 20 business incubating services items. It is desirable to perform the strategy for the satisfaction. Secondly, basic business incubating services were interpreted as the one-dimensional quality like incubating spaces, parking facilities, security facilities, industry technology development funds, and incubating managers. Finally, training and educational service was recognized as indifferent quality. Futhermore, the improvement and the limitation of this study as well as the interpretation of analysis results are also provided.

This research constructs a data set regarding competition policy through a comprehensive review of previous studies, and performs a meta-analysis to quantitatively assess the price effects of deregulation. A structural econometric model is used to eliminate possible biases from heterogeneity of the studies,such as in publication types and measurement methods. Four types of regulations that deter competition are characterized and three groups of industries are made for drawing practical implications. We fnd that deregulation to promote competition reduces prices by 0.23% and that these estimated price effects are more stable when we control for the publication types and measurement ways. Easing regulations that restrict consumers' choice is shown to be most effcient in promoting competition, lowering prices by 0.7%. This is followed by eliminating the limitation in the number of frms in the industry, with 0.2% price reduction. Overall, the network and service industries are shown to be more responsive to deregulation than the R&D industry. These results could shed light on policy implementation when a pro-competition policy is called for due to restrictive regulations in the corresponding industries.

I have outlined the history of Korean Fisheries Co - coperatives and its economic and noneconomic contribution to Korean Fisheries. But in order to overcome new economic world trend that is emerging now with the beginning of the WTO Korean Fisheries Co - operatives should change itself. It can be summarlized as follows. (1) The early Korean Fisheries Co - operatives was monopolized by Japanese under the Japanese colonial rule. (2) The modern Korean Fisheries Co - operatives was organized in 1962. 4. 1 by Korean government. (3) Korean Fisheries Co - operatives was weak in democratic management because of socioeconomic bad condition. (4) In spite of the dependence on the government financial aid Korean Fisheries Co - operatives has contributed to the fisheries development. (5) At the aid of the credit undertaking economic project was enlarged greatly, (6) With the close of the UR talks we cannot but open out fisheries market. So we are in condition that must enforce out fisheries compatability. especially, \circled1 Improvement of fisheries structure to enlarge management scale \circled2 Increase of productivity in fishing ground \circled3 The continuous endeavour to positive marine resourses making (7) Reorganization of fisheries, for example fisheries system or fisheries structure (8) Reexamination of the organization and operation of Korean Fisheries Co - operatives. And taking a proper step to improve their weak points. (9) The strengthening of the activity of investigation and study in centural Fisheries Co - operatives (10) It needs a special study to establish a few target or object in the management of Fisheries Co - operatives. When we could solve these ones mentioned above our fisheries will develop again.

Purpose Real estate usually takes charge of the highest proportion of physical properties which individual, organizations, and government hold and instability of real estate market affects the economic condition seriously for each economic subject. Consequently, practices for predicting the real estate market have attention for various reasons, such as financial investment, administrative convenience, and wealth management. Additionally, development of machine learning algorithms and computing hardware enhances the expectation for more precise and useful prediction models in real estate market. Design/methodology/approach In response to the demand, this paper aims to provide a framework for forecasting the real estate market with machine learning algorithms. The framework consists of demonstrating the prediction efficiency of each machine learning algorithm, interpreting the interior feature effects of prediction model with a state-of-art algorithm, LIME(Local Interpretable Model-agnostic Explanation), and comparing the results in different cities. Findings This research could not only enhance the academic base for information system and real estate fields, but also resolve information asymmetry on real estate market among economic subjects. This research revealed that macroeconomic indicators, real estate-related indicators, and Google Trends search indexes can predict real-estate prices quite well.

The purpose of this study is to look into the question-What kind of factors, among various influencing factors of temple architecture, change the development of villages with their its relationships to the temple. For the study, the villages located around a temple site with special geographic characteristics were chosen. It was analyzed and generalized what kind of social factors were chosen and applied to the design of residential buildings in those villages. The characteristics of the buildings in the villages that have relationships with the temple appeared to be as follows; Financial factor of the temple, rather than religious influences of it, appeared to influence strongly over the forms of building and the spaces of village. The village which formed along a new entrance axis to the temple were transformed to have a spatial organization along with added sightseeing and commercial functions. The villages have different spatial structures depending on their land uses. In short, the form of entrance axis to the temple has changed the economical dependence of villages on the temple, and becomes the major factor of transforming the spatial organization of the villages.

This paper provides an overview of the experiences of the people's housing process (PHP) in South Africa. The discussion is done against the backdrop of the different outcomes of the government public housing provision initiative, commonly known as the Reconstruction and Development Programme (RDP) that directly produced more than three million subsidized housing to formerly segregated and disadvantaged populations. Notwithstanding the huge success in providing the much needed accommodation to such previously marginalized communities, the over-reliance on direct provision has the PHP ostensibly less impactful in housing delivery. Against the backdrop of the soaring housing backlogs, concerns with housing quality and the financial difficulties as well as the shrinking fiscal space; the article recommends improved support of the PHP. This can be achieved by the adoption of innovations that make land and minimal infrastructure and services available to the urban poor and to support their initiatives of self-building.
