This study aimed to explore the over-efficacy in problem solving and overconfidence of knowledge of students performing assessments in two different test formats: multiple-choice and supply-type. Two hundred and four female middle school students participated in this study. Multiple-choice and supply-type formats of tests on photosynthesis were used, and each item contained scales indicating one's self-efficacy on problem-solving and confidence of knowledge. The results showed that the correlation coefficients of performance between the two different assessment formats were less than 0.5 and the correlation coefficients between efficacy/confidence and actual performance were less than 0.45. Moreover, students tended to exhibit more over-efficacy and overconfidence in multiple-choice formats. The percentage of over-efficacy and overconfidence was higher in the group that completed the multiple-choice test first followed by the supply-type assessment than in the group that started with the supply-type followed by the multiple-choice assessment. From this study, it can be suggested that more use of supply-type assessment is required in science education. If test administrators require the combination of both multiple-choice and supply-type in an assessment, the supply-type assessment format should come first so that students can maintain the appropriate level of efficacy and confidence. In addition, science educators need to develop new learning programs to enhance students' self-monitoring skills of their problem-solving ability and knowledge.

As the supply and demand of pork has become a significant concern in Korea, controlling it has become a critical challenge for the industry. However, compared to the demand for pork, which has relatively stable consumption, it is not easy to maintain a stable supply. As the preparation of measures for a supply-demand crisis response and supply control in the pig industry has emerged as an important task, it has become necessary to establish a stable supply model and create an appropriate manual. In this study, a pork supply prediction model is constructed using reported data from the pig traceability system. Based on the derived results, a method for determining the supply-demand crisis stage using a statistical approach was proposed. From the results of the analysis, working days, African swine fever, heat wave, and Covid-19 were shown to affect the number of pigs graded in the market. A test of the performance of the model showed that both in-sample error rate and out-sample error rate were between 0.3 - 7.6%, indicating a high level of predictive power. Applying the forecast, the distribution of the confidence interval of the predicted value was established, and the supply crisis stage was identified, evaluating supply-demand conditions.

There are various presentation methods of apparel products on the internet shopping mall. The objective of this study was (a) to identify the effect of information supply about the criteria to evaluate a garment according to presentation methods and (b) to investigate the relation between the consumer's evaluation of presentation methods and confidence in purchase decision. For this experiment. 4 presentation methods of jean were selected from internet shopping mall. They were rotating appearance on the body, enlarged product picture, apparel items coordination method and just picture of wearing appearance. Each presentation method was evaluated by panels using questionnaire. Consumer's evaluation of presentation methods were developed 5 point likert scale. The major findings drawn from this study were as follows : 1. There were significant differences in degree of information supply about product criteria according to presentation methods. Enlarged product picture introduction was good for confirmation of sewing state, fabric and detail. Apparel items coordination method was good for judgement of styling and current fashion suitability. 2. Dimension of information evaluation was composed of providing pleasure, utility of information, reliability & attractiveness, negative emotions. All of these factors affect confidence in purchase decision and intention of revisiting the site. The most important factor for confidence in purchase decision making was reliability & attractiveness. as compared to this, intention of revisiting the site was more influenced by providing pleasure.

This paper dealt with FMEA, which is a method of the analysis to secure safety and confidence coming up to customers'expectation in consideration of the environment of the corporation, the industrial environment, and the functional improvement. And by using FMEA, We showed the example analyzed the confidence of the Air Supply System. It was proved by the result of the analysis that the rate of the breakdown which is usually regarded as the first important point to reform can't satisfy the selecting basis to improve. Also the result said that it is not right to depend on only the rate of the failure in making the list of the reform. Through the analysis of the breakdown, FMEA can present the important factors of the reform to improve the confidence of the system. In this study would show the important factors of the improvement in order to product the goods guaranteed confidence through the method of FMEA.

The purpose of this paper is to discuss the impact of the New Container Security Initiatives of U.S., CSI(Container Security Initiative) and C-TPAT(Customs-Trade Partnership against Terrorism). The CSI which aims to pre-screen high-risk containers in ports of loading. It is a unilateral effort that seeks to develop bi-lateral agreements between the United States and foreign countries with significant container trade volumes into the U.S. C-TPAT is a voluntary initiative to develop cooperative security relationships between the U.S. government and U.S. firms in the global supply chain. Government and Industry have already responded with proposals to create more confidence in supply chain security. These proposals call for heightened inspection and scrutiny of the goods flowing through a supply chain, increased information exchange among participants of supply chain. While government and the private sector are working together to launch new initiative to create more secure and reliable supply chains, industry is rapidly exploring the potential of new technologies such as RFID. The security recommendations will eventually become the requirements to be complied with by importers and their supplier extending to the carriers. It is needed that Korean shippers involved in US importer's supply chain should pay attention to the requirements and start implementing the security measures.

Companies are required to have adequate understanding and awareness of a partner company within the supply chain, together with the understanding of the imbalance consequent on power types. Therefore, this study intends to look into the power types and make clear their influence on confidence & commitment and causal relationship that is linked to SCM user satisfaction. The concrete research results are as follows. First, the result showed that none of the behavioral coercive, high-handed reward, and relative legitimacy in terms of Mediated power had a significant influence on confidence and commitment. Like this, the result explains that there is a limit to forcibleness power in forming a continuous, long-term relationship. Second, business expertise, professional information and value reference in terms of Non-Mediated power were all found to have a significant influence on confidence and commitment. This could be judged as having an intention of aggressively accepting a partner company's expertise, information strength and imitable culture, etc. Third, both confidence and commitment was found to have a significant influence on SCM user satisfaction.
