Today's competitive global market makes most enterprise endeavor to specialize their business areas, and co-operate with trading partners in supply chain by the forms of collaboration, information and business process sharing. However, even the supply chain plan generated by co-operation often fails to be executed successfully, because it was generated without capacities of suppliers and more over nested suppliers. To overcome this limitation, the supply chain plan of an enterprise should be generated truly integrated way. In this paper, we classify business patterns based on scenarios about quotation processing and supply chain planning in self-integrated environment. And we present business process models about four business patterns and describe them, which are classified by whether request for quotation includes information about price, required time periods, and quantity for each required time period and whether it is received from customer or sent to supplier. In addition, we describe the types of supply chain planning problem.

High-utility itemset mining (HIUM) has emerged as a key data-mining paradigm for object-of-interest identification and recommendation systems that serve as frequent itemset identification tools, product or service recommendation systems, etc. Recently, it has gained widespread attention owing to its increasing role in business intelligence, top-N recommendation, and other enterprise solutions. Despite the increasing significance and the inability to provide swift and more accurate predictions, most at-hand solutions, including frequent itemset mining, HUIM, and high average- and fast high-utility itemset mining, are limited to coping with real-time enterprise demands. Moreover, complex computations and high memory exhaustion limit their scalability as enterprise solutions. To address these limitations, this study proposes a model to extract high-utility frequent closed itemsets based on an improved cumulative summary list structure (CSLFC-HUIM) to reduce an optimal set of candidate items in the search space. Moreover, it employs the lift score as the minimum threshold, called the cumulative utility threshold, to prune the search space optimal set of itemsets in a nested-list structure that improves computational time, costs, and memory exhaustion. Simulations over different datasets revealed that the proposed CSLFC-HUIM model outperforms other existing methods, such as closed- and frequent closed-HUIM variants, in terms of execution time and memory consumption, making it suitable for different mined items and allied intelligence of business goals.

The relationship of the local unit village organizations and the commons has a very complicated character. In the rural areas of Korea, there are still many village organizations that were made during the period of Japanese colonial rule (1910-1945) and the era of the Park Chung-hee's military government rule (the early 1960s). First of all, there is a development committee which were made at the time of Park's military administration. The committee has several subordinate organizations, such as senior citizens association, youth association, women's association which are involved in the decision making structure of the community. Those organizations are related indirectly with commons, so they exercise their influence over the management and disposal of commons of the community. In each village, there are some organizations to manage commons like union of ranches, forest GYE (*It's like 'association'), fishing village GYE. In many cases, those members were matched up with the committee's and were organized at the colonial period and the period of the military regime. However, organizations linked to commons have been keeping rules and norms of resource management and have been gaining a relative autonomy for a long time before organizing them in the top-down ways. The relationship between local unit village organizations and the commons has been defined by the development paradigm. The development committees, and senior citizens association and youth association have accepted the idea of modernizing rural areas. The modernized time, they have sold the village's land to external capital. But they also took the part of a role to preserve the village's commons through the managing the asset owned by the village at times. So in some villages, the organizations play a leading role to sell a asset of the village, and in another villages, the organizations take a core role not to sell it. The purpose of this report is to explain the complex activities for the using and managing the commons of local unit villages in Jeju island which is called 'Commons Island' due to hold many commons in South Korea. Through this research, we expect to be able to provide more rich discussion on how the village's internal cultural and organizational characteristics work with commons recognition and practice triggered by changes in external conditions.
