Purpose - This paper is to examine the work of a third party in the process of import and export management. In other words, the purpose of this paper is investigate the status and functional role of a third party in relation to each terms of the trade contract. Research design, data, methodology - This study consists of 5 chapters through literature survey. It will examine the involvement of the third party through each terms. Chapter 1 introduction, Chapter 2 deals with trade contracts, Chapter 3 investigates the shipping terms, payment terms, and insurance terms, and Chapter 4 reviews with commercial arbitration. And in Chapter 5, it looks at the conclusion and implications. Results - The relevant party in the import and export management process may be a third party through outsourcing, not the principal. At this time, in fulfilling each condition of trade, it can be seen that the implementation of tasks through the participation of a third party with high expertise can more smoothly and productively implement the overall import and export management. Therefore, it can be seen that the implementation of the trade business in which the third party participated can be interpreted in terms of derivative effects and at the same time can be a way to improve the principal's competitiveness procedurally. Conclusions -Through this study, in the import and export management, the performance of the work through the agent makes the entire process more smooth and efficient. Outsourcing of roles using the expertise of a third party, a subcontractor rather than a principal, is desirable and important.

As the Jordanian government is in the process of implementing accrual-based IPSAS, this study aims to provide academics' perspectives on the effective implementation of accrual-based IPSAS in Jordan to authorities and regulators. The findings of a survey of 124 accounting professors at Jordanian institutions reveal that adopting accrual-based IPSAS will aid in presenting the realistic financial status of governmental bodies, with various advantages to adopting accrual-based IPSAS (e.g., enhance assets and liabilities management, decision-making process, transparency, expenditures management). On the other side, we discovered that change is met with reluctance because the majority of public-sector accountants are untrained and unqualified to apply the accrual-based IPSAS. Another main challenge is the cost of implementing the accrual-based IPSAS in the Jordanian public sector is very high. To address these issues, employees should be motivated by providing suitable training programs, reward systems, and top management support and commitment to a successful transition. Finally, we suggested that Jordanian governments commit to using IPSAS in the public sector to increase residents' socioeconomic advantages. Public sectors should implement IPSASs for improved management, transparency in financial reporting, accountability, and regulatory and supervisory agencies.

This study aims to propose the implementation of innovative payment models in Korea in order to promote the financial sustainability of the national health insurance system by reviewing the current status of the payment system in Korea and examining other countries' experiences with various innovative payment models. Korea primarily uses a fee-for-service payment system and additionally uses various payment systems such as case payment, per diem, and pay-for-performance. However, each payment system has its limitations. Many OECD (Organization for Economic Cooperation and Development) countries have pointed out the limitations of existing payment systems and have been attempting various innovative payment models (e.g., add-on payment, bundled payment, and population-based payment). Therefore, it is essential for Korea to consider innovative payment models, such as a mixed payment model that takes into account the strengths and weaknesses of each payment system, and to design and pilot these models. This process requires stakeholders to work together to build a social consensus on the implementation of innovative payment systems and to refine legal and systematic aspects, develop an integrated health information system, and establish dedicated organizations and committees. These efforts towards innovative payment models will contribute to developing a sustainable health insurance system that ensures the public's health and well-being in Korea.

소규모 상점은 상품 관리를 대부분 수기에 의존하고 있다. 이러한 수기 관리는 다양한 제품의 입출고 현황을 관리하는데 제한적이며 실시간 상품현황 관리는 별도의 통계 시스템을 이용해야 한다. 이러한 문제점을 해결하기 위해 개발된 기존의 POS 시스템은 고가의 비용 및 공간의 제약으로 중대형 및 특수매장 위주로 운용되고 있다. 이 때문에 소규모 상점의 수기에 의한 상품관리 대신 비용부담이 적지만 자동화된 새로운 상품관리 시스템이 필요하다. 본 논문에서는 NFC 기능을 탑재한 스마트폰을 활용하여 소규모 상점에서 판매되는 상품을 실시간으로 관리할 수 있는 시스템을 개발하였다.

The purposes of this study were to investigate the perception of nutrition labeling on restaurant menus, and to analyze the differences among subject's characteristics, eating-out behaviors, and dietary attitudes. Information concerning general characteristics, health status, eating-out behaviors and dietary attitudes of subjects was collected by a structured questionnaire. From January 5th to February 27th in 2009, 406 questionnaires were completed by 157 males and 249 females. Statistical analyses were performed using by SPSS 14.0 package program. The perception of the importance of nutrition labeling was 3.89, while knowledge of whether restaurants provided sufficient nutrition information scored 2.26 indicating that being highly conscious of nutrition labeling, respondents did not view the supplied information as sufficient. Nutritional perception was greater in females and varied in both genders with age and health status. Significant differences concerning the perceptions of nutrition labeling were evident, based on eating-out behaviors and dietary attitudes. The results imply that nutrition labeling on restaurant menus should be based on consumer characteristics. Relevant nutrition labeling might help improve health by encouraging proper dietary habits and providing valuable nutritional information. Recognition of the importance of nutrition labeling and strategic implementation of labeling in menus would be prudent strategies for restaurant managers.

Line scan camera has been widely used in the area of inspection of glass, film, fabric, iron, PCB and etc. due to the high resolution and the high speed. We developed the line scan based vision system to inspect tangled and cut-off status of yarn in the manufacturing process. The original image is binarized with a proper threshold, and the gap distances in the yarn are measured in real time, so finally the status of the process is decided by the maximum value of the gap distance. All procedures are executed in real time by realization of multi-processed threads. By implementation of this system, the error of the yarn in manufacturing process can be precedently monitored and the loss of the yarn is decreased efficiently.
