This study attempted to examine the profitability and marketing costs of seed potato under contract farming system of BADC (Bangladesh Agricultural Development Corporation) with the help of primary and secondary data. Total 45 contract farmers were randomly selected. Attempts were made to calculate costs, returns and profitability of seed potato production under contract farming system, and to identify marketing channels of seed potato. The field level data were collected by a farm survey during the months of April 2005 through direct interviews with contract farmers and registered dealers using a structure survey questionnaire. The results showed that the gross return per hectare was Tk. 252,464 for all categories of farms. Cost of seeds, fertilizers, pesticides, irrigation and human labor were critical inputs for profitability of seed potato. Cobb-Douglas production function analysis was used to determine the effects of the key variables to seed potato production under contract farming system. The elasticity of seed potato production was at 0.727 for all categories of farms. The findings exhibited that the summation of elasticity of different inputs for seed potato production was less than one, implying that the production function exhibited decreasing returns to scale. Registered dealers and Upazila Sales Centers were involved in seed potato marketing formed a straightforward marketing channel. The total marketing costs of registered dealers were Tk. 759.49 per ton of seed potato. The net marketing margin of registered dealers was estimated at Tk. 465.51 per ton of seed potato. The selected contract farmers and registered dealers faced a number of problems and some of recommendations were suggested.

The object of International License Contract is technology. Technology is means to produce visible goods, which are human's intellectual creations such as Intellectual Property Right - patent, design, trademark- and Know-how. Unlike visible goods which decrease as being used, these technologies are possible to be produced expansively and develop additionally. Therefore, the way to make a contract of goods is a sales contract which transfers ownership while technology follows license contract which gives approval of use for a certain period. International license contract means that licensor has right to possess, allows licensee to use licensed technology for a fixed period and takes royalty. So there are various matters such as selection of the duration of a contract, confirmation of technology range, competition limitation, technique guidance and support, calculation of royalty, withholding tax between parties. This study examines licensor's grant of license and competition limitation. Intellectual property rights fundamentally give exclusive rights to the creator so the licensor use or dispose of his or her intellectual property rights at will. Technology transfer is possible through license contract because of this right. But licensor must exercise his or her intellectual property rights within a reasonable limit. It means, when licensor makes an unreasonable demand abusing his or her position, it is regarded as competition limitation clause and the deal itself may become null. Therefore, restraint on competition needs to be examined in detail as it influences on contract validity. Each country has their own competition laws for establishing a fair market order and inspection guide and guideline for judging whether there is any unfair act related to intellectual property rights. Judgment on intellectual property rights is subject the technology-introduced country's domestic laws and thus, contracting parties each need to precede opposite nation's domestic laws system.

The Purpose of this paper is to compare workfare system in UK with in Australia from the view point of social contract theory. There are two kinds of social contract theory - Hobbesian and Kantian theory. In view of these two types, this paper makes a comparative study of New Deal in UK and Mutual Obligation in Australia. The results of analysis can be summarized as follows. Firstly, in this respect of compulsive program formation background, Mutual Obligation and New Deal is all similar with Hobbesian social contract theory. Secondly, With regard to concern for the disadvantaged, Mutual Obligation is among Hobbesian social contract but New Deal is among Kantian social contract. Lastly, concerning orientation of compulsion, Mutual Obligation is close to Hobbesian social contract but New Deal is close to Kantian social contract.

By committing to a long-term replenishment contract, suppliers can mitigate the pressure to find new customers and afford to charge a discounted price to buyers seeking to lower their purchasing costs. In this paper, we develop an analytical model from buyer's perspective for the contracting process to investigate the buyer-supplier interactions. Based on the developed model, we propose an algorithm to derive optimal strategy for the contract. We consider a system with a single buyer and a supplier in a situation where the buyer's inventory is controlled by (R, S) policy under VMI setting. According to the contract, the supplier should replenish the buyer's inventory up to a fixed level every R times during a specified period. The buyer purchases any deficient amount from a spot market at a higher price. We show by computational experiment that our proposed algorithm finds the global optimum solution.

User satisfaction is the most critical criteria in measuring information systems success or failure. In this study, Contract Foodservice Information Systems were evaluated with user satisfaction instrument based on previous work. A total of 70 Contract Foodservice Information Systems users was surveyed. The status of building area of Contract Foodservice Information Systems was more in foodservice management (M=3.74), but less in producing (M=2.53) and pruchasing (M=3.02) management. The users recognized .accuracy of information (M=4.27), lasting educational services on systems (M=4.34) and increasing work productivity (M=4.42) as the most important factors and they also recognized it was important factors to build systems such area database management, menu management, purchasing and producing management and foodservice management (p<.01.).

The material analysis of an offshore structure is generally conducted in the contract design phase for the price quotation of a new offshore project. This analysis is conducted manually by an engineer, which is time-consuming and can lead to inaccurate results, because the data size from previous projects is too large, and there are so many materials to consider. In this study, the piping materials in an offshore structure are analyzed for contract design using a big data framework. The big data technologies used include HDFS (Hadoop Distributed File System) for data saving, Hive and HBase for the database to handle the saved data, Spark and Kylin for data processing, and Zeppelin for user interface and visualization. The analyzed results show that the proposed big data framework can reduce the efforts put toward contract design in the estimation of the piping material cost.

As e-business being rapidly developed the importance of security is on the rise in network. Intrusion detection systems which are a core security system detect the network intrusion trial. As intrusions become more sophisticated, it is beyond the scope of any one IDS to deal with them. Thus we placed multiple IDS agents in the network and the information helpful for detecting the intrusions is shared among these agents to cope effectively with attackers. Each agent cooperates through the BBA (Black Board Architecture) and CNP (Contract Net Protocol) for detecting intrusions. In this paper, we propose the effective method comparing the blackboard architecture to contract net protocol.

This paper deals with $\ulcorner$Requirement Decision Model for Repair Parts supplied by the Government$\lrcorner$ which is to reduce Aircraft Contract Maintenance Cost. It aims to find solutions to the fundamental problems of the Aircraft Contract Maintenance System. Under the current Aircraft Contract Maintenance System, it is hard to forecast the exact demand of repair parts, so support rate of Repair Parts supplied by the Government is restricted under 50 percent. It is inevitable to purchase Repair Parts from the firm with much higher price than those of Government source. However, absence of fixed demand pattern makes it difficult to improve accuracy of demand forecast. As a solution to these problems, this model prevents a cost increase due to the unit price difference between Repair Parts supplied by the Government and Repair Parts purchased by the Firm. It also reflects demand characteristics of each repair part, and prevents continual stock increase by setting an upper limit on the amount of Repair Parts supplied by the Government. The effectiveness of this model is verified by empirical analysis using the latest raw data. By applying this model to real situation, we expect to reduce about 4 billion won every year.

The purpose of this study is to improve regulations such as law and standard contract forms related to defects liability in Korea. Defects liability has been one of the major causes of construction contract disputes in Korea in recent years. It is important to avoid or resolve disputes regarding defects liability through regulations containing clear criteria and to specify the standard regarding the mitigation and remission of the contractor's defects liability. This study was carried out through document research and analysis of judicial precedents. The following are the courses of improvement regarding the mitigation and remission of defects liability in Korea. First, laws and standard contract forms must contain more detailed clauses regarding exemption of a contractor's defects liability, which clearly set out the scope of the defects liability of the contractor. Second, the current system for defects liability favors the owner rather than the contractor - it is necessary to change the defects liability system in order to give the owner and the contractor an equal standing. Third, strict liability is taken on by the contractor even when the term of guarantee for defects lasts longer than the legally set period of liability for defects. Hence, it is necessary to improve the system by alleviating the liability of the contractor through applying negligence liability as opposed to strict liability during the term of guarantee.
