In supply chain management, the supply contract can induce collaboration and coordination among the supply chain members in order to optimize supply chain performance. Numerous supply contracts have been examined; however, some difficulties related to the application of these contracts still occur. One of the solutions is to apply the composite supply contract which can assist in the supply chain coordination. This research examines the composite contract of the revenue sharing and quantity flexibility contracts in a two-stage supply chain, which comprises a retailer and a supplier. In this research, a mathematical model of the composite contract is developed; then, the applicability of the proposed composite contract is examined by investigating its capability in terms of supply chain coordination and profit allocation. In the numerical experiments, the composite revenue sharing-quantity flexibility contract showed that it is superior to both component contracts in terms of supply chain coordination and profit allocation among supply chain members.

This study primarily concerns the Model Contract for International Sale of Manufactured Goods recently published by International Chamber of Commerce in 2020. To this end, this study examines the importance of the ICC model contract and its main characteristics, and considers in what form the contract is composed of and the scope of its application by classifying it according to the object of the contract, the subject and type of the transaction. In addition, this study divides the main contents of the ICC model contract into special conditions and general conditions, and attempts to scrutinize details of each condition in connection with the United Nations Convention on Contracts for International Sale of Goods(1980) as a governing law taken by the ICC model contract. Furthermore, this study puts forward, on the basis of the detailed examination of main conditions of ICC Model Contract, practical implications on what the parties to the contract should be aware of when using the ICC model contract.

This study examined the effects of employers' breach of safety obligation and violation of psychological contract on the workers' safety behaviors and turnover intention. Especially, this study examined a mediating effect of violation of psychological contract on the relationship between employer's breach of safety obligation and workers' safety behavior and turnover. 198 workers were asked to respond to the questionnaires that measured various demographic variables, employers' breach of safety obligation, violation of psychological contract, safety behavior, turnover intention. A hierarchical regression was conducted to identify variables that had significant relationships between employers' breach of safety obligation and employees' safety behavior and turnover intention, and to examine the mediating effect of violation of psychological contract. Results indicated that the employers' breach of safety obligation significantly predicted both workers' safety behaviors and turnover intention. It was also found that the violation of psychological contract was a significant predictor for both workers' safety behavior and turnover intention. In addition, violation of psychological contract was found as mediating effect on the relationship between employers' breach of safety obligation and workers' safety behavior and turnover intention. Based on these results, the implications of this study and suggestions for future research were discussed.

Smart contract, one of the applications of blockchain, is expected to be used in various industries. However, there is risks of damages caused by attacks on vulnerabilities in smart contract codes. Tool support is essential to detect vulnerabilities, and as new vulnerabilities emerge and smart contract implementation languages increase, the tools must have extensibility for them. We propose a design model for extensible architecture of smart contract vulnerability detection tools that detect vulnerabilities in smart contract source codes. The proposed model is composed of design pattern-based structures that provides extensibility to easily support extension of detecting modules for new vulnerabilities and other implementation languages of smart contract. In the model, detecting modules are composed of independent module, so modifying or adding of module do not affect other modules and the system structure.

This research investigates the supply chain contract between a distributor and a supplier in which the selling period is relatively short in comparison with long production lead time. At the first stage, supplier who is a Stackelberg leader offers the distributor a contract with a set of parameters, and subjected to those parameters, the distributor places the number of initial orders as well as options. In order to purchase the option, the distributor pays non-linear option premium price with respect to the number of purchased options. At the second stage, based on realized demand, the distributor has the right to exercise option as either put or call which is limited up to the number of purchased options. The wholesale price contract is used as a benchmarking contract. This research has confirmed that the supply chain contract with a non-linear option premium price can help to coordinate the supply chain.

Purpose - This study examines the factors that influence the performance of contract farming by agricultural cooperatives from the agency theory and resource-based view of the firm. Design/methodology/approach - This study collected 1,090 data related to a sample of contract information between agricultural cooperatives and producers from national agricultural cooperatives federation. In order to examine the performance of contract farming, we use the multiple regression analysis. Findings - Incentives may reduce agency problems by increasing producers' motivation and discouraging their opportunistic behavior. Total asset size and education expenses function like resources that lessen the risks coming from environment uncertainty, and also facilitate the contract farming between producers and agricultural cooperatives. Research implications or Originality - By analyzing the factors that influence on the performance of contract farming between producers and agricultural cooperatives, we propose that incentives, and resources may improve the performance of contract farming between agricultural cooperatives and producers. Overall, the contract farming can co-create the economic efficiency and effectiveness while minimizing risks and uncertainty.
