The contract is essential for the employment, the labor contracts standardize the right and duty for the employment, but the psychological contract is another type of contract. A psychological contract is an employee's belief about the mutual obligations, and it balances the relationship between the employee and his/her organization. In order to promote the corporation's competition, the corporation carries out the restructuring and downsizing strategies, but these strategies are contrary to the critical role that people play in successful organization. Under this condition, the employee's belief and loyalty become more important to maintain the balance of relationship between employee and his organization. When the psychological contract was violated, it may lead to reduce the employee's belief, loyalty, job satisfaction and performance, citizenship behavior, even the employees will turn- over. However, the react may be affected by the individual's discrepancy and external circumstances. The case study is based on the employees in Yueng Foong Yu Paper MFG. CO., LTD. so as to prove if the psychologial contract violation will reduce the employee's performance, and some factors deal with how to affect the violation of psychological contract and work performance. The result is shown as the following: 1. In different SEU(Strategic Entrepreneurial Units¡^, the performance of the employees in the general management office is better than the Fine Paper and Board SEU. 2. In the sexual difference, the task performance of the female employees is better than that of the male ones. 3. In the workage, the employees whose contextual performance are from 11 to 15 years are better than the ones whose workage are over 25 years. 4. The difference between psychological contract violation and work performance is insignificant. 5. When the employees whose orgnizational commitment is higher feel more satified with the organizational benefits, his/her task performance becomes worse. 6. The difference between employability, personal characteristics and work performance is significant. 7.The differecne between relationship of employers and employees and contextual performance is significant.

This article explains the particular conformation and dynamic of the integrativeelements of the relationship between the tangible and intangible aspects in the processof local development  of San Juan  Nuevo  de Parangaricutiro (Michoacán, México). On one hand, the historical characteristics and their connection to the way thecommunity faces natural adversity; on the other, the creation of a participative and democratic leading style and the role of selection in the constitution of social capital and the local endogenous nucleus. In the same way, the decisive role played by the intangible aspects, in specific, the role of the meta local forces, in this dynamic is emphasized. The author supports the idea that local development is the result of a dynamic of feedback and mutual  growth among the tangible and intangible aspects, in a sequence that starts with the maturation and accumulation of one of these aspects in the community, widening the possibilities of development. In this dynamic, the role played by the meta local forces operating in the backings of the collective memory, long term linking the different moments of the process and serving as factors of re­ impulse within the feedback, is decisive. The author also explores the importance of the public policies in the successive moments of the dynamic between tangibles and intangibles in the local development and the concept of reversibility in the construction of this dynamic. / El artículo explica la particular conformación y dinámica de los elementos constitu­tivos de la relación entre los aspectos tangibles e intangibles en el proceso de desarrollo local de San Juan Nuevo de Parangaricutiro (Michoacán, México). Por un lado, los aglutinantes históricos y su vinculación con la forma en que la comunidad encara las adversidades naturales; por otro, la generación de un liderazgo de participación incipientemente democrático, así como el papel de la selección en la constitución de capital social y del núcleo endógeno local. Asimismo, se subraya el papel decisivo jugado por los aspectos intangibles y, especialmente, por lasfuerzas meta locales den­ tro de esta dinámica. Se sostiene que el desarrollo local es el resultado de una dinámi­ ca de retroalimentación y escalamiento mutuo entre los aspectos tangibles e intangibles, en una secuencia que se inicia con la maduración y acumulación de alguno de estos dos aspectos en la localidad, lo que abre las posibilidades de desarrollo. En esta diná­ mica, es decisivo el papel cumplido por las fuerzas meta locales que operan en el trasfondo de la memoria colectiva vinculando a largo plazo los distintos momentos del proceso y sirviendo de factores de reimpulso dentro de la retroalimentación. Se plantea también la importancia de las políticas públicas en los sucesivos momentos de la dinámica entre tangibles e intangibles en el desarrollo local, así como el concep­to de reversibilidad en la construcción de esta dinámica.
